    Clinical trial: once-daily mesalamine granules for maintenance of remission of ulcerative colitis , a 6-month placebo-controlled trial

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 8 2010
    G. R. Lichtenstein
    Aliment Pharmacol Ther 2010; 32: 990,999 Summary Background, Ulcerative colitis (UC) is a chronic relapsing and remitting idiopathic inflammatory bowel disorder. Aim, To evaluate once-daily mesalamine (mesalazine) granules (MG) for maintenance of remission of UC. Methods, Randomized, double-blind, placebo-controlled trial of patients (n = 209 MG, n = 96 placebo) with UC in remission [revised Sutherland Disease Activity Index (SDAI) rectal bleeding = 0, mucosal appearance <2] who took MG 1.5 g or placebo once-daily for up to 6 months. Primary efficacy endpoint: the percentage of patients who remained relapse-free at month 6/end of treatment. Relapse was defined as SDAI rectal bleeding score ,1 and a mucosal appearance score ,2, a UC flare, or initiation of medication to treat a UC flare. Results, The percentage of relapse-free patients at month 6/end of treatment was higher with MG than placebo (78.9% vs. 58.3%, P < 0.001) in the intent-to-treat analysis. Significant differences (P , 0.025) favouring MG were observed for most secondary endpoints including improvement in rectal bleeding, physician's disease activity rating, stool frequency, the SDAI at month 6/end of treatment, patients classified as a treatment success and relapse-free duration. The incidence of adverse events was similar between groups. Conclusions, Once-daily mesalamine (mesalazine) was effective in maintaining remission of UC for 6 months. [source]


    Pilot study: the use of sulfasalazine for the treatment of acute pouchitis

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 2 2010
    A. BELLUZZI
    Summary Background, Acute pouchitis, an idiopathic inflammatory condition of the ileal pouch anal anastomosis, is the most frequent complication after proctocolectomy for ulcerative colitis. Aim, To test the hypothesis that sulfasalazine (SASP) might have a synergistic beneficial effect in acute pouchitis, by combining the anti-inflammatory activity of 5-aminosalicylic Acid and the bacteriostatic effect of sulphapyridine. Methods, Twenty two patients were investigated for acute pouchitis; the Pouchitis Disease Activity Index (PDAI) was calculated and 11 patients with acute pouchitis (PDAI >7) were included in an open study, after obtaining their informed consent. Patients were treated with SASP 500 mg tablets, two tablets three times per day (3000 mg daily), for 2 months. Pouch endoscopy with biopsies was performed at the entry and at the end of the study. Results, According to the PDAI score, 8/11 patients (73%) improved their clinical condition and 7/11 (63%) were in remission at the end of the treatment. At 8 weeks, the median PDAI index decreased from 11.2 ± 2.3 to 6.6 ± 4.7 P < 0.01. No adverse events or toxicity were reported and all patients completed the study. Conclusions, Despite the limitations of the current study, sulfasalazine seems to be a potential treatment for acute pouchitis. Aliment Pharmacol Ther,31, 228,232 [source]


    Prospective assessment of the effect on quality of life of anti-tumour necrosis factor therapy for perineal Crohn's fistulas

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 7 2009
    S. C. NG
    Summary Background, Anti-tumour necrosis factor (TNF) therapy effectively treats Crohn's perineal fistulas (CPF); the effect on health-related quality of life (HRQoL) remains unknown. Aims, To evaluate the effect of anti-TNF therapy on the HRQoL of patients with CPF in daily clinical practice. Methods, Prospective evaluation of clinical and magnetic resonance imaging (MRI) responses, disease activity (Perianal Disease Activity Index , PDAI), and HRQoL assessment [Inflammatory Bowel Disease Questionnaire (IBDQ)] in patients receiving anti-TNF therapy for CPF treated up to 12 months. Results, In all, 26 patients with CPF were treated (mean age 39 years; 19 infliximab, 7 adalimumab). At baseline, 85% patients had impaired IBDQ scores (mean 137; ,normal' >170). At 12 months, mean increases in IBDQ score for infliximab and adalimumab treated patients were 40 and 41 points respectively (P < 0.05). There were significant improvements in all IBDQ subscores (bowel, emotional, systemic, social) at 12 months (all P , 0.003). Fourteen patients (74%) on infliximab and six on adalimumab (86%) achieved IBDQ score ,170. Mean increase in IBDQ score was 50, 34 and 16 points in patients with clinical fistula closure (P < 0.001), clinical response (P = 0.002) and no response (n = 1) respectively. IBDQ score increased for patients with MRI healing (P < 0.001) and MRI improvement (P = 0.016), but not for those with no MRI change (n = 2). IBDQ correlated significantly with PDAI at baseline and at 12 months. Conclusion, Anti-TNF therapy improves HRQoL in patients with CPF at 12 months and this improvement is most pronounced in patients with clinical and MRI healing. [source]


    Evaluation of the meaningfulness of health-related quality of life improvements as assessed by the SF-36 and the EQ-5D VAS in patients with active Crohn's disease

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 9 2009
    G. COTEUR
    Summary Background, Crohn's disease (CD) is a chronic inflammatory illness characterized by episodic abdominal pain, diarrhoea, fever, bleeding and obstruction. While the Crohn's Disease Activity Index (CDAI) remains the most commonly accepted measure for assessing the disease status in clinical trials, patient-reported outcome (PRO) instruments are being utilized more frequently to provide information about health-related quality of life (HRQOL). To facilitate interpretation of results, it is common to identify a meaningful unit of PRO score change, such as a minimal clinically important difference (MCID). Aim, To define and apply MCID estimates for the SF-36 and EuroQol-5D visual analogue scale (EQ-5D VAS) for use in CD treatment evaluation. Methods, Data from two phase III randomized controlled trials of certolizumab pegol were utilized. MCID estimates were computed from one trial using anchor-based and distribution-based methods. These estimates were applied to data from the other trial. Results, SF-36 PCS and MCS MCID estimates ranged from 1.6 to 7.0 and 2.3 to 8.7 respectively, depending on approach. EQ-5D VAS MCID estimates ranged from 4.2 to 14.8. Conclusions, For the first time, the MCID values provided interpretation guidelines for PRO results in CD. This research demonstrates that patients treated with certolizumab pegol benefit from meaningful and sustained HRQOL improvements. [source]


    A Clinical Index for Disease Activity in Cats with Chronic Enteropathy

    JOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 5 2010
    A.E. Jergens
    Background: There is a need for a clinically useful, quantitative index for measurement of disease activity in cats with chronic enteropathy (CE). Objective: To develop a numerical activity index that is of practical value to clinicians treating CE in cats. Animals: Eighty-two cats with CE. Methods: Retrospective case review of 59 cats diagnosed with inflammatory bowel disease (IBD). Prospective validation study of 23 cats having either IBD or food-responsive enteropathy (FRE). Multivariate regression analysis was used to identify which combination of clinical and laboratory variables were best associated with intestinal inflammation of IBD. This combination of variables was expressed in a score that was used as an activity index for the prospective assessment of disease activity and of the effect of treatment in cats with IBD or FRE. Results: The combination of gastrointestinal signs, endoscopic abnormalities, serum total protein, serum alanine transaminase/alkaline phosphatase activity, and serum phosphorous concentration had the best correlation with histopathologic inflammation and comprise the feline chronic enteropathy activity index (FCEAI). Positive treatment responses in cats with CE were accompanied by significant (P < .05) reductions in FCEAI scores after treatment. Conclusions and Clinical Importance: The FCEAI is a simple numerical measure of inflammatory activity in cats with CE. The scoring index can be reliably used in the initial assessment of disease severity for both IBD and FRE and as a measure of clinical response to treatment for these disorders. [source]

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 5 2009
    B. SHEN
    Summary Background, Crohn's disease (CD) of the pouch can develop in patients with ileal pouch-anal anastomosis (IPAA). Scant data are available on the treatment of this disease entity. Aim, To evaluate efficacy and safety of adalimumab in treating CD of the ileal pouch. Methods, From June 2007 to June 2008, 17 IPAA patients with inflammatory (n = 10), fibrostenotic (n = 2) or fistulizing (n = 5) CD of the pouch treated with adalimumab were evaluated. Inclusion criteria were CD of the pouch who failed medical therapy and were otherwise qualified for permanent pouch diversion or excision. All qualified patients received the standard dosing regimen of subcutaneous injection adalimumab (160 mg at week 0, 80 mg at week 1, and 40 mg every other week thereafter). Complete clinical response was defined as resolution of symptoms. Partial clinical response was defined as improvement in symptoms. Endoscopic inflammation before and after therapy was recorded, using the Pouchitis Disease Activity Index (PDAI) endoscopy subscores. Results, The median age was 36 years with 12 patients (70.6%) being male. At 4 weeks, seven patients (41.2%) had a complete symptom response and 6 (35.3%) had a partial response. There was also a significant improvement in the PDAI endoscopy subscores at week 4 (P < 0.05). At the last follow-up (median of 8 weeks), eight patients (47.1%) had a complete symptom response and 4 (23.5%) had a partial response. Four patients (23.6%) developed adverse effects. Three patients (17.7%) eventually had pouch failure after failing to respond to adalimumab therapy. Conclusion, Adalimumab appeared to be well-tolerated and efficacious in treating CD of the pouch in this open-labelled induction study. [source]


    Oral, colonic-release low-molecular-weight heparin: an initial open study of Parnaparin-MMX for the treatment of mild-to-moderate left-sided ulcerative colitis

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 5 2008
    L. PASTORELLI
    Summary Background, Efficacy of heparin and low-molecular-weight heparins (LMWHs) in inflammatory bowel disease (IBD) treatment has been suggested. The multimatrix oral formulation MMX releases active drugs in the colon, avoiding systemic absorption. Parnaparin sodium is the LMWH chosen to be carried in the MMX formulation. Aim, To assess the safety of three different oral dosages (70, 140 and 210 mg once daily) of Parnaparin-MMX (CB-01-05) in left-sided ulcerative colitis (UC). Methods, Left-sided UC patients, with a mild-to-moderate relapse were enrolled. All patients received Parnaparin-MMX for 8 weeks. Clinical Activity Index (CAI), Disease Activity Index (DAI), Endoscopic Activity Index and IBD-QoL were assessed throughout the study. A strict clinical and laboratory follow-up, including assessment of anti-factor Xa activity, was performed. Clinical remission was defined as CAI <4. Results, Ten UC patients were enrolled. One patient retired for clinical deterioration. No relevant side effects, including either interference with haemostasis parameters or increased bleeding, were observed. At the end of the treatment, seven patients (70%) were in clinical remission, only one achieving endoscopic healing. Mean final CAI, DAI and IBD-QoL scores were significantly improved from baseline. Conclusions, Parnaparin-MMX appears to be a safe treatment option in mild-to-moderate UC. Controlled studies are warranted. [source]


    Infliximab regulates lamina propria T lymphocytes in patients with Crohn's disease

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 2006
    O. WATANABE
    Summary Background and Aims The immune system is a major determinant of the pathophysiological inflammation, which may lead to gastrointestinal mucosal injury in patients with Crohn's disease. Cytokines such as tumour necrosis factor-alpha are well-known mediators of the immune system, and treatment with a chimeric anti-tumour necrosis factor-alpha antibody (infliximab) has been shown to be highly effective in patients with Crohn's disease. Recent evidence indicates that infliximab induces apoptosis in lamina propria T lymphocytes in these patients. To better understand the mechanisms of infliximab's effect on gastrointestinal inflammation, we investigated changes in the serum level of cytokines after treatment in these patients, and the effect of infliximab in inducing the apoptosis of T lymphocytes. Methods Thirteen patients with Crohn's disease were treated with infliximab at a dosage of 5-mg/kg body weight. Clinical response was evaluated using the Crohn's Disease Activity Index, and serum soluble interleukin-2 receptor, interleukin-6, tumour necrosis factor-alpha levels were analysed by enzyme-linked immunosorbent assay at 0 and 2 weeks after treatment. Apoptosis of peripheral and lamina propria T lymphocytes after culture with infliximab was detected by flow cytometry. Results Crohn's Disease Activity Index decreased in 12 of 13 patients, and serum soluble interleukin-2 receptor, interleukin-6 and tumour necrosis factor-alpha levels decreased in most patients after treatment with infliximab. Tumour necrosis factor-alpha level before treatment in the six patients in whom Crohn's Disease Activity Index decreased by more than 70 was <5 ng/mL. Infliximab induced the apoptosis of lamina propria but not of peripheral T lymphocytes. Conclusion These findings suggest that a low level of serum tumour necrosis factor-alpha is an indicator for infliximab treatment. The induction of apoptosis of lamina propria T lymphocytes by infliximab may be an important mechanism of its anti-inflammatory effect in patients with Crohn's disease. [source]


    Cyclophosphamide pulse therapy followed by azathioprine or methotrexate induces long-term remission in patients with steroid-refractory Crohn's disease

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 2 2006
    C. SCHMIDT
    Summary Background In patients with steroid-refractory Crohn's disease, the therapeutic goal is to achieve both rapid remission and maintenance of clinical response. Aim To evaluate the long-term benefit in patients treated with cyclophosphamide pulse therapy and azathioprine or methotrexate, a combination shown to be effective in a recent pilot study. Methods Sixteen patients with acute steroid-refractory Crohn's disease participated in a prospective open-labelled uncontrolled pilot study between December 1998 and June 2003. All had a median number of 4 monthly pulses of intravenous cyclophosphamide (750 mg) and were followed until relapse of the disease. Results Thirteen of 16 patients (81%) achieved remission within 8 weeks after two pulses of cyclophosphamide in combination with azathioprine or methotrexate, with a Crohn's Disease Activity Index decrease from 294 to 111 (median). Remission sustained for 19 months (median, range: 1,45). Moreover, eight patients with pyoderma gangrenosum and erythema nodosum who responded to cyclophosphamide have maintained their remission for up to 30 months. Conclusions In steroid refractory patients with Crohn's disease, cyclophosphamide is highly effective to induce remission. This uncontrolled study indicates that cyclophosphamide-induced remission is long-lasting under standard immunosuppressive therapy. [source]


    Trial of trefoil factor 3 enemas, in combination with oral 5-aminosalicylic acid, for the treatment of mild-to-moderate left-sided ulcerative colitis

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 11 2005
    A. Mahmood
    Background :,Current treatment of ulcerative colitis is imperfect. Trefoil peptides are known to stimulate repair in many models of injury, including animal models of colitis. Aim :,To assess the efficacy of trefoil factor family-3 enema treatment in a clinical trial. Methods :,A total of 16 patients with mild-to-moderate left sided ulcerative colitis were recruited into a double-blind randomized placebo-controlled study. Patients taking steroids or with proctitis only were excluded. Patients received 75 mL enemas containing either human recombinant trefoil factor family-3 (10 mg/mL) or saline alone once a day for 14 days. All patients also received an oral dose-increment of 1.2 g of mesalazine daily above their normal usage. Patients were assessed at 0, 2, 4 and 12 weeks. Remission was defined as Ulcerative Colitis Disease Activity Index of 0 or 1 with no blood in stool. Individual clinical improvement was defined as a Ulcerative Colitis Disease Activity Index reduction of >3. Data was analysed using chi-square test and anova. Results :,Median Ulcerative Colitis Disease Activity Index at entry were 8.5 (trefoil factor family-3 group) and 8 (placebo group). Analysed on an intention-to-treat basis, only one patient went into remission (in trefoil factor family-3 group at day 28). Clinical improvement was seen in two trefoil factor family-3 and three placebo patients on day 14 and two patients in each group on day 28. Conclusion :,Increasing the dose of 5-aminosalicylic acid was moderately effective in reducing the Ulcerative Colitis Disease Activity Index but was insufficient to induce remission. Trefoil factor family-3 enemas were well-tolerated but did not provide additional benefit above that of adding additional 5-aminosalicylic acid alone. [source]


    An open-labelled study of granulocyte colony-stimulating factor in the treatment of active Crohn's disease

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 4 2005
    J. R. Korzenik
    Summary Background :,Immunodeficiency syndromes associated with a Crohn's-like illness suggest innate immune defects may lead to Crohn's disease. Anecdotal cases using haemopoietic colony-stimulating factors report improvement in intestinal disease associated with these syndromes. Aim :,To test the safety and efficacy of recombinant human granulocyte colony-stimulating factor in active Crohn's disease. Methods :,In an open-labelled 12-week trial, patients with a Crohn's Disease Activity Index between 220 and 450 were treated with recombinant human granulocyte colony-stimulating factor (filgrastim, Neupogen). Concomitant immunosuppressants were prohibited except prednisone ,20 mg/day. Patient's received recombinant human granulocyte colony-stimulating factor 300 mcg daily subcutaneously adjusted to achieve an absolute neutrophil count between 25 and 35 × 109/L. Results :,Twenty patients were enrolled with a mean initial Crohn's Disease Activity Index of 307 (range: 234,428). Fifteen patients (75%) completed 8 weeks; 13 patients (65%) completed 12 weeks with the mean Crohn's Disease Activity Index for patients continuing through those times of 196 (range: 36,343) and 162 (range: 20,308), respectively. At week 12, 11 patients (55%) demonstrated a decrease of at least 70 points; five (25%) achieved a sustained remission. The mean decrease was statistically significant at each assessment time-point. Three of four patients with fistulae had a positive response. Adverse effects included bone pain, mostly mild resolving with continued treatment. One patient was hospitalized with a viral-like syndrome but it is uncertain if this was treatment related. Conclusion :,Recombinant human granulocyte colony-stimulating factor is safe and potentially effective therapy for active Crohn's disease. [source]


    Minimal renal dysfunction in inflammatory bowel disease is related to disease activity but not to 5-ASA use

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 3 2001
    K. R. Herrlinger
    Background: Conflicting data exist about proteinuria in inflammatory bowel diseases. It is still unclear whether the occurrence of proteinuria in inflammatory bowel disease patients is an extra-intestinal manifestation of disease or the result of adverse effects to medication, especially to aminosalicylates (ASA). Methods: A total of 95 patients (51 with Crohn's disease and 44 with ulcerative colitis) were enrolled in the study. Disease activity was assessed by Crohn's Disease Activity Index (CDAI) or the Truelove index, respectively. Urine was collected over 24 h and protein excretion of specific marker proteins for tubular (,1-microglobulin-,1-MG) and glomerular (albumin-Alb, Immunoglobulin G-IgG) dysfunction was measured using a highly sensitive immunoluminometric assay. Results: Out of 51 Crohn's disease patients, 20 showed elevated urinary ,1-MG. The amount of ,1-MGuria was strongly correlated to the CDAI (r=0.6, P < 0.001). Only four Crohn's disease patients showed slightly elevated values for glomerular proteins in urine. Similar results were obtained for ulcerative colitis: whereas only two ulcerative colitis patients showed albuminuria, tubular proteinuria was detected in 28 out of 44 ulcerative colitis patients. Proteinuria was strongly dependent on disease activity (P < 0.01) but was not related to ASA treatment. Conclusions: Proteinuria of tubular marker proteins occurs in the majority of inflammatory bowel disease patients and is related to disease activity rather than to ASA treatment. Tubular proteinuria seems to reflect a renal extra-intestinal manifestation of inflammatory bowel disease and may serve as a new relevant marker of disease activity. [source]


    The good initial response to therapy with a combination of traditional disease-modifying antirheumatic drugs is sustained over time: The eleven-year results of the Finnish rheumatoid arthritis combination therapy trial

    ARTHRITIS & RHEUMATISM, Issue 5 2009
    Vappu Rantalaiho
    Objective To evaluate the evolution of functional and clinical outcomes over 11 years in patients with early rheumatoid arthritis (RA) initially treated with a combination of 3 disease-modifying antirheumatic drugs (DMARDs) or with a single DMARD. Methods A cohort of 199 patients with early active RA were initially randomized to receive treatment with a combination of methotrexate, sulfasalazine, and hydroxychloroquine with prednisolone or treatment with a single DMARD (initially, sulfasalazine) with or without prednisolone. After 2 years, the drug treatment strategy became unrestricted, but still targeted remission. At 11 years, function was assessed with the Health Assessment Questionnaire (HAQ), and clinical outcomes were assessed with the modified Minimal Disease Activity (MDA) measure and the American College of Rheumatology (ACR) criteria for remission. Results At 11 years, 138 patients were assessed (68 in the combination-DMARD group and 70 in the single-DMARD group). The mean ± SD HAQ scores were 0.34 ± 0.54 in the combination-DMARD group and 0.38 ± 0.58 in the single-DMARD group (P = 0.88). Modified MDA was achieved by 63% (95% confidence interval [95% CI] 51, 77) and by 43% (95% CI 32, 55) (P = 0.016) of the combination-DMARD group and the single-DMARD group, respectively, and ACR remission by 37% (95% CI 26, 49) and by 19% (95% CI 11, 29) (P = 0.017), respectively. Conclusion Initial therapy with a combination of DMARDs in early RA results in higher rates of patients achieving modified MDA and strict ACR remission even over the long term than initial single-DMARD therapy. Targeting remission with tight clinical controls results in good functional and clinical outcomes in most RA patients. [source]


    Does primary sclerosing cholangitis impact quality of life in patients with inflammatory bowel disease?

    INFLAMMATORY BOWEL DISEASES, Issue 3 2010
    Ashwin N. Ananthakrishnan MD
    Abstract Background: Impairment of health-related quality of life (HRQoL) is an important concern in inflammatory bowel disease (IBD; ulcerative colitis [UC], Crohn's disease [CD]). Between 2%,10% of patients with IBD have primary sclerosing cholangitis (PSC). There has been limited examination of the disease-specific HRQoL in this population compared to non-PSC IBD controls. Methods: This was a retrospective, case,control study performed at a tertiary referral center. Cases comprised 26 patients with a known diagnosis of PSC and IBD (17 UC, 9 CD). Three random controls were selected for each case after matching for IBD type, gender, age, and duration of disease. Disease-specific HRQoL was measured using the Short Inflammatory Bowel Disease Questionnaire (SIBDQ). Disease activity for CD was measured using the Harvey,Bradshaw index (HB) and using the UC activity index for UC. Independent predictors of HRQoL were identified. Results: There was no significant difference in the age, gender distribution, or disease duration between PSC-IBD and controls. There was no difference in use of immunomodulators or biologics between the 2 groups. Mean SIBDQ score was comparable between PSC-IBD patients (54.5) and controls (54.1), both for UC and CD. Likewise, the disease activity scores were also similar (2.8 versus 3.1, P = 0.35). On multivariate analysis, higher disease activity score (,1.33, 95% confidence interval [CI] 95% CI ,1.85 to ,0.82) and shorter disease duration were predictive of lower HRQoL. Coexisting PSC did not influence IBD-related HRQoL. There was a higher proportion of permanent work disability in PSC-IBD (7.7%) compared to controls (0%). Conclusions: PSC does not seem to influence disease-specific HRQoL in our patients with IBD but is associated with a higher rate of work disability. (Inflamm Bowel Dis 2010) [source]


    Does nicotine influence cytokine profile and subsequent cell cycling/apoptotic responses in inflammatory bowel disease?

    INFLAMMATORY BOWEL DISEASES, Issue 11 2008
    Marian C. Aldhous PhD
    Abstract Background: Smoking differentially influences susceptibility to the inflammatory bowel diseases (IBDs) Crohn's disease (CD) and ulcerative colitis (UC). We investigated the effects of nicotine on cytokine, cell cycle, and apoptotic responses in peripheral blood mononuclear cells (PBMCs) from IBD patients and healthy controls (HCs). Methods: PBMCs from IBD patients and HC were stimulated with lipopolysaccharide (LPS; 1 ,g/mL) or phytohemagglutinin (PHA, 5 or 0.5 ,g/mL), ± nicotine (1, 10, 100 ,g/mL). Cytokines (IL1,, IL2, IL10, IL12/IL23p40, TGF,, TNF,) were measured in supernatants at 24 hours. After 72 hours cells were analyzed by flow cytometry for cell cycle and apoptosis. Statistical modeling was used to identify interactions between cytokines and cell cycle / apoptosis and minimize confounding effects. Results: Stimulation by LPS and PHA (5 ,g/mL) increased IL12/IL23p40 production from CD and UC versus HC (P < 0.05); PHA (0.5 ,g/mL) increased IL1, in UC and decreased TGF, from CD and UC (P < 0.01). In all groups, nicotine reduced LPS- and PHA (0.5 ,g/mL)-stimulated production of IL1,, IL10, TGF,, and TNF, (P < 0.001). Cell cycle analysis showed that PHA, but not LPS, induced proliferation and decreased G0/G1 resting cells in CD and UC versus HC (P < 0.001). Nicotine decreased PHA-stimulated S-phase proliferation and increased G0/G1 resting cells (P < 0.01). Modeling showed independent associations between IL12/IL23p40 and apoptosis (P = 0.01), IL1, and resting cells (P = 0.006), TNF, and proliferating cells (P < 0.001). Disease activity and smoking habit had no effect. Conclusions: Dysregulated cytokine profiles in UC and CD are associated with specific alterations in cell cycle responses; these effects may be modified by nicotine, and potentially by anticytokine therapies.

    Fecal calprotectin is useful in predicting disease relapse in pediatric inflammatory bowel disease

    INFLAMMATORY BOWEL DISEASES, Issue 5 2008
    Dorota Walkiewicz MD
    Abstract Background: Fecal calprotectin (FC) has been proposed as a noninvasive surrogate marker to determine the degree of intestinal inflammation and predicting relapse in patients with inflammatory bowel disease (IBD). The aim was to compare FC levels in IBD and healthy controls, to correlate FC levels with clinical disease activity, and to assess whether FC levels can be used to predict clinical relapse in children with IBD. Methods: Enzyme-linked immunosorbent assay (ELISA) determined levels of FC were measured in more than 1 stool samples (n) from 32 IBD patients (n = 97) and from 34 healthy controls (n = 37). Disease activity was assessed by the Harvey,Bradshaw index in Crohn's disease (CD) and by Physician's Global Assessment (PGA) in both CD and ulcerative colitis (UC). Clinical events were recorded up to 9 months following stool collection in CD patients. Wilcoxon rank sum test and Fisher's exact tests were used to compare FC levels in IBD patients and in control. Kaplan,Meyer analysis was used to determine a risk of clinical relapse in relation to FC levels. Results: The IBD group had higher FC levels (range 17,7500 g/g) compared with control (16,750 g/g, P < 0.0001). FC levels were higher during relapse (CD, 3214 ± 2186; UC, 2819 ± 1610) compared to remission (CD, 1373 ± 1630; UC, 764 ± 869; P < 0.0001). Among those with clinical relapse, 90% had FC levels more than 400 ,g/g in CD. Eighty-nine percent of CD encounters with FC levels less than 400 ,g/g remained in clinical remission. Conclusions: FC levels differentiate active IBD from controls. Among children with CD and in remission, FC levels may be useful in predicting impending clinical relapse.

    Assessing health-related quality of life in patients with inflammatory bowel disease in Zhejiang, China

    JOURNAL OF CLINICAL NURSING, Issue 1-2 2010
    Yunxian Zhou
    Aims., The aim of this study was to assess health-related quality of life in patients with inflammatory bowel disease in Zhejiang, Mainland China. Background., The incidence of inflammatory bowel disease in China is believed to be low but has been increasing in the past decade. The quality of life of Chinese patients with inflammatory bowel disease is unknown. Design., A cross-sectional study. Methods., The study was conducted in 92 patients with inflammatory bowel disease in Zhejiang, China, 52 with ulcerative colitis and 40 with Crohn's disease. Health-related quality of life was measured by the Chinese version of the Inflammatory Bowel Disease Questionnaire and Short Form-36, respectively. Disease activity was assessed by the Walmsley and Harvey,Bradshaw simple indices for ulcerative colitis and Crohn's disease, respectively. Demographic and clinical variables were also recorded. Short Form-36 data from the study sample were compared with a reference population of 1688 Chinese people residing in Hangzhou, Zhejiang, China. Results., No significant health-related quality of life differences were found between patients with ulcerative colitis and Crohn's disease (p > 0·05). Pooled data showed that inflammatory bowel disease patients with active disease had significantly lower scores for all eight dimensions of Short Form-36 compared to those in remission (p < 0·01); those with active disease scored significantly lower than population norms in all dimensions of Short Form-36 except mental health (p < 0·05); whereas those in remission scored significantly lower than population norms in role physical (p < 0·01) and general health dimensions (p < 0·05). The regression analyses identified only disease activity index and employment status to explain variations in health-related quality of life (p < 0·01). Conclusions., Inflammatory bowel disease similarly impairs health-related quality of life in patients with both ulcerative colitis and Crohn's disease. Relevance to clinical practice., The results suggest that any interventions that produce a stable clinical remission, whether medical or surgical, allowing patients to return to their usual work position can decrease the disease impact on their daily lives.

    Infliximab improves inflammation and anthropometric measures in pediatric Crohn's disease

    JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 4 2010
    Daniel M Sinitsky
    Abstract Background and Aim:, Infliximab (IFX) is a monoclonal antibody licensed to treat medically refractory Crohn's disease (CD). Our aim was to elucidate the effects of IFX therapy on clinical, growth and serum parameters in children with CD in a single pediatric center in Sydney, Australia. Methods:, A retrospective case series review of children treated with IFX for CD at Sydney Children's Hospital, Australia was undertaken, with a review of outcomes after starting IFX. Main outcome measures were response and remission (as measured according to improvements in Pediatric Crohn's Disease Activity Index scores and Physician Global Assessment), laboratory markers (C-reactive protein, erythrocyte sedimentation rate, hemoglobin, white cell count, lymphocytes, neutrophils, platelets, albumin) and growth (Z scores). Results:, The 16 patients included had a mean age at first infusion of 13.0 years (1.25,17.5 years). Six of 12 patients (with adequate data available) were in remission at 2 weeks following the first infusion. At 1 year, 10 of 12 patients (83%) were in remission. Mean C-reactive protein and erythrocyte sedimentation rate had fallen significantly (P < 0.05) at 2 weeks (from 29 to 7 mg/L and 40 to 19 mm/h, respectively). Positive trends were observed for all other parameters, excluding lymphocytes and white cell count. At 1 year, mean Z score for body mass index improved significantly from ,0.9 to ,0.1 (P < 0.01). Conclusions:, Disease activity subsides in most children treated with IFX for CD. IFX therapy also improves some growth parameters. The pattern of improvement requires further elucidation, as the results in the present study suggest differing dosing frequency of infusion may achieve better efficacy. [source]


    Fecal lactoferrin, myeloperoxidase and serum C-reactive are effective biomarkers in the assessment of disease activity and severity in patients with idiopathic ulcerative colitis

    JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 11 2009

    Abstract Background and Aim:, Disease activity and severity of ulcerative colitis (UC) is assessed using colonoscopy, which is invasive, costly and has poor patient acceptability. The role of non-invasive biomarkers of intestinal inflammation in the evaluation of patients with UC is not known. The aim of the study was to examine the role of serum C-reactive protein (SCRP), fecal myeloperoxidase (FMPO) and fecal lactoferrin (FLF) in assessing disease severity, activity and response to therapy. Methods:, Consecutive patients with idiopathic UC (IUC) attending our hospital from July 2005 to September 2006 were studied. All underwent clinical, endoscopic and histological assessment for disease activity, extent, severity and estimation of SCRP, FMPO and FLF levels at baseline and follow up (FU). An equal number of healthy age-matched controls were studied for biomarker levels. Results:, A total of 37 patients (mean age 37 ± 12 years) were studied. All three biomarkers were elevated more often in the cases than in the controls (all P = 0.000). Cases with severe IUC had higher CRP, MPO and FLF titers than those without severe IUC. At FU, a significant fall in biomarker levels paralleled the reduction in Mayo's scores. All three biomarkers showed a high degree of correlation with each other. The areas under the curve for FLF, MPO and CRP were 1.00, 0.867 and 0.622, respectively. The sensitivity and specificity of markers were: FLF (94%, 100%), FMPO (89%, 51%) and SCRP (24%, 100%). Conclusion:, Biomarkers are useful in assessing disease activity, severity and response to therapy in patients with UC. They showed a high degree of correlation with each other. [source]


    Faecal lactoferrin , a novel test to differentiate between the irritable and inflamed bowel?

    Aliment Pharmacol Ther,31, 1365,1370 Summary Background, Distinguishing between inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS) can be challenging. Aims, To investigate the utility of faecal lactoferrin as a marker of inflammation in patients with IBD, IBS and controls. Methods, Disease activity in IBD patients was assessed using the modified Harvey,Bradshaw Activity Index. Stool samples were analysed using an ELISA assay. Results, We recruited 137 patients with IBS, 126 with ulcerative colitis (UC) and 104 with Crohn's disease (CD), and 98 healthy volunteers. The median ± IQ lactoferrin concentration (,g/g faecal weight) was 0 ± 1.4 for IBS patients, 6.6 ± 42 for UC patients, 4 ± 12.7 for CD patients and 0.5 ± 2 for healthy controls. Lactoferrin levels were significantly higher in IBD patients compared with IBS/healthy controls (P < 0.001). The median lactoferrin concentrations were significantly higher in active UC & CD patients compared with inactive patients (P < 0.001 and P = 0.002 respectively). The sensitivity, specificity, positive and negative predictive values of lactoferrin in distinguishing active IBD from IBS/healthy controls were 67% and 96%, 87% and 86.8% respectively. Conclusions, Lactoferrin is useful to differentiate between IBD and IBS, and can be used as an adjunct to blood parameters to determine IBD patients who have ongoing inflammation. [source]


    Early changes in rectal nitric oxide and mucosal inflammatory mediators in Crohn's colitis in response to infliximab treatment

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 8 2007
    T. LJUNG
    SUMMARY Background Treatment with tumor necrosis factor-, monoclonal antibody (infliximab) reduces clinical activity and intestinal inflammation in Crohn's disease. Aim To study the time-course of the effects of infliximab with reference to mucosal cytokine and inducible nitric oxide synthase expression. Methods Thirty-two patients with Crohn's disease were treated with single dose infliximab (5 mg/kg). Disease activity was assessed days 1, 3, 7 and 28 using Harvey,Bradshaw index. Rectal nitric oxide levels were determined and rectal biopsies collected before treatment, 1 h after infusion and on days 3, 7 and 28. Immunohistochemical staining against inducible nitric oxide synthase, tumor necrosis factor-,, interleukin-1, and interferon-, were performed. Results Clinical response was seen in 14 patients with down-regulation of global immunohistochemistry expression, reaching nadir day 3. Rectal nitric oxide was increased at baseline (3578 ± 1199 parts per billion, ppb) compared with controls (89 ± 13 ppb) (P < 0.001). In patients with clinical response, rectal nitric oxide decreased from 3926 ± 1687 ppb to 1050 ± 428 ppb day 28 (P < 0.05). Conclusions Down-regulation of mucosal inflammatory mediators occurs after infliximab. Rectal nitric oxide levels parallel down-regulation of inducible nitric oxide synthase, tumor necrosis factor-,, interleukin-1, and interferon-, and may serve as a quantitative biomarker of intestinal inflammation.

    Efficacy of Lactobacillus GG in maintaining remission of ulcerative colitis

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 11 2006
    M. A. ZOCCO
    Summary Background Aminosalicylates are the mainstay of therapy to prevent relapse of quiescent ulcerative colitis. The rationale for using probiotics is based on the evidence implicating intestinal bacteria in the pathogenesis of this disorder. Aim To evaluate the efficacy of Lactobacillus GG alone or in combination with mesalazine vs. mesalazine as maintenance treatment in ulcerative colitis. Patients and methods 187 ulcerative colitis patients with quiescent disease were randomized to receive Lactobacillus GG 18 × 109 viable bacteria/day (65 patients), mesalazine 2400 mg/day (60 patients) or Lactobacillus GG + mesalazine (62 patients). Disease activity index, endoscopic and histological scores were determined at 0, 6 and 12 months and in case of relapse. The primary end point was to evaluate sustained remission. Results Overall analysis showed no difference in relapse rate at 6 (P = 0.44) and 12 months (P = 0.77) among the three treatment groups. However, the treatment with Lactobacillus GG seems to be more effective than standard treatment with mesalazine in prolonging the relapse-free time (P < 0.05). Conclusions Lactobacillus GG seems to be effective and safe for maintaining remission in patients with ulcerative colitis, and it could represent a good therapeutic option for preventing relapse in this group of patients.

    Summary Background : Bovine colostrum is a rich source of nutrients, antibodies and growth factors. Aim : To examine the efficacy of colostrum enemas in the treatment of distal colitis using a randomized, double-blind, controlled protocol. Methods : Fourteen patients (eight female), with a mean age of 45 years (range, 16,75 years) and mild to moderately severe distal colitis (Powell-Tuck scoring system), received colostrum enema (100 mL of 10% solution) or placebo (albumin solution) b.d. for 4 weeks. Both groups also received mesalazine (1.6 g/day) or, if already taking it, had a dose increment of 1.6 g/day. Disease activity was documented at 0, 2 and 4 weeks. Results : After 4 weeks, the colostrum group showed a mean reduction in symptom score of ,,2.9 (95% confidence interval (CI), ,,5.4 to ,,0.3), whereas the placebo group showed a mean response of +,0.5 (95% CI, ,,2.4 to +3.4). The histological score improved in five of the eight patients in the colostrum group (mean response, ,,0.9; 95% CI, ,,1.69 to ,,0.03), whereas the histological scores only improved in two of the six patients in the placebo group (mean response, 0.2; 95% CI, ,,2.4 to +2.6). Conclusions : Bovine colostrum enema shows potential as a novel therapy for left-sided colitis with additional benefits over using mesalazine alone. Further studies appear to be warranted. [source]


    Minimal renal dysfunction in inflammatory bowel disease is related to disease activity but not to 5-ASA use

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 3 2001
    K. R. Herrlinger
    Background: Conflicting data exist about proteinuria in inflammatory bowel diseases. It is still unclear whether the occurrence of proteinuria in inflammatory bowel disease patients is an extra-intestinal manifestation of disease or the result of adverse effects to medication, especially to aminosalicylates (ASA). Methods: A total of 95 patients (51 with Crohn's disease and 44 with ulcerative colitis) were enrolled in the study. Disease activity was assessed by Crohn's Disease Activity Index (CDAI) or the Truelove index, respectively. Urine was collected over 24 h and protein excretion of specific marker proteins for tubular (,1-microglobulin-,1-MG) and glomerular (albumin-Alb, Immunoglobulin G-IgG) dysfunction was measured using a highly sensitive immunoluminometric assay. Results: Out of 51 Crohn's disease patients, 20 showed elevated urinary ,1-MG. The amount of ,1-MGuria was strongly correlated to the CDAI (r=0.6, P < 0.001). Only four Crohn's disease patients showed slightly elevated values for glomerular proteins in urine. Similar results were obtained for ulcerative colitis: whereas only two ulcerative colitis patients showed albuminuria, tubular proteinuria was detected in 28 out of 44 ulcerative colitis patients. Proteinuria was strongly dependent on disease activity (P < 0.01) but was not related to ASA treatment. Conclusions: Proteinuria of tubular marker proteins occurs in the majority of inflammatory bowel disease patients and is related to disease activity rather than to ASA treatment. Tubular proteinuria seems to reflect a renal extra-intestinal manifestation of inflammatory bowel disease and may serve as a new relevant marker of disease activity. [source]


    Erythrocyte C3d and C4d for monitoring disease activity in systemic lupus erythematosus

    ARTHRITIS & RHEUMATISM, Issue 3 2010
    Amy H. Kao
    Objective Disease activity in systemic lupus erythematosus (SLE) is typically monitored by measuring serum C3 and C4. However, these proteins have limited utility as lupus biomarkers, because they are substrates rather than products of complement activation. The aim of this study was to evaluate the utility of measuring the erythrocyte-bound complement activation products, erythrocyte-bound C3d (E-C3d) and E-C4d, compared with that of serum C3 and C4 for monitoring disease activity in patients with SLE. Methods The levels of E-C3d and E-C4d were measured by flow cytometry in 157 patients with SLE, 290 patients with other diseases, and 256 healthy individuals. The patients with SLE were followed up longitudinally. Disease activity was measured at each visit, using the validated Systemic Lupus Activity Measure (SLAM) and the Safety of Estrogens in Lupus Erythematosus: National Assessment (SELENA) version of the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Results At baseline, patients with SLE had higher median levels of E-C3d and E-C4d (P < 0.0001) in addition to higher within-patient and between-patient variability in both E-C3d and E-C4d when compared with the 2 non-SLE groups. In a longitudinal analysis of patients with SLE, E-C3d, E-C4d, serum C3, and anti,double-stranded DNA (anti-dsDNA) antibodies were each significantly associated with the SLAM and SELENA,SLEDAI. In a multivariable analysis, E-C4d remained significantly associated with these SLE activity measures after adjusting for serum C3, C4, and anti-dsDNA antibodies; however, E-C3d was associated with the SLAM but not with the SELENA,SLEDAI. Conclusion Determining the levels of the erythrocyte-bound complement activation products, especially E-C4d, is an informative measure of SLE disease activity as compared with assessing serum C4 levels and should be considered for monitoring disease activity in patients with SLE.

    Methotrexate polyglutamate concentrations are not associated with disease control in rheumatoid arthritis patients receiving long-term methotrexate therapy,

    ARTHRITIS & RHEUMATISM, Issue 2 2010
    Lisa K. Stamp
    Objective There are limited data suggesting that methotrexate polyglutamate (MTXGlu) concentrations can guide MTX dosing in patients with rheumatoid arthritis (RA). The aim of this study was to define a therapeutic range of red blood cell (RBC) MTXGlun concentrations (where n refers to the number of glutamate groups), including threshold values for efficacy and adverse effects in patients receiving long-term oral MTX treatment. Methods A cross-sectional study of 192 patients receiving oral MTX was undertaken. Disease activity was assessed by the swollen and tender joint counts, the C-reactive protein level, and the Disease Activity Score in 28 joints (DAS28). High disease activity was defined as a DAS28 of >3.2. A standardized questionnaire regarding common MTX adverse effects was completed. Results The MTX dosage was significantly higher in patients in whom the swollen joint count and DAS28 were higher. The MTXGlu4, MTXGlu5, MTXGlu3,5, and MTXGlu1,5 concentrations were significantly higher in patients with high disease activity. After correction for age, the estimated glomerular filtration rate, and the MTX dosage, the association remained significant for MTXGlu5. RBC folate concentrations were significantly higher in the group with high disease activity. There was no association between any MTXGlun concentration and adverse effects. Conclusion In contrast to other studies, the results of the present study did not show a relationship between the MTXGlun concentration and reduced disease activity in patients with RA who were receiving long-term MTX therapy. However, disease activity was influenced by the RBC folate level, which may be a more important factor than MTXGlun concentrations for disease control. In accordance with the findings of previous studies, we were unable to show a relationship between MTXGlun concentrations and adverse effects. Prospective studies will be important to determine whether there is a role for measuring MTXGlun concentrations in patients receiving long-term treatment with MTX. [source]


    Tocilizumab in systemic lupus erythematosus: Data on safety, preliminary efficacy, and impact on circulating plasma cells from an open-label phase I dosage-escalation study,

    ARTHRITIS & RHEUMATISM, Issue 2 2010
    Gabor G. Illei
    Objective To assess the safety of interleukin-6 receptor inhibition and to collect preliminary data on the clinical and immunologic efficacy of tocilizumab in patients with systemic lupus erythematosus (SLE). Methods In an open-label phase I dosage-escalation study, 16 patients with mild-to-moderate disease activity were assigned to receive 1 of 3 doses of tocilizumab given intravenously every other week for 12 weeks (total of 7 infusions): 2 mg/kg in 4 patients, 4 mg/kg in 6 patients, or 8 mg/kg in 6 patients. Patients were then monitored for an additional 8 weeks. Results The infusions were well tolerated. Tocilizumab treatment led to dosage-related decreases in the absolute neutrophil count, with a median decrease of 38% in the 4 mg/kg dosage group and 56% in the 8 mg/kg dosage group. Neutrophil counts returned to normal after cessation of treatment. One patient was withdrawn from the study because of neutropenia. Infections occurred in 11 patients; none was associated with neutropenia. Disease activity showed significant improvement, with a decrease of ,4 points in the modified Safety of Estrogens in Lupus Erythematosus National Assessment version of the Systemic Lupus Erythematosus Disease Activity Index score in 8 of the 15 evaluable patients. Arthritis improved in all 7 patients who had arthritis at baseline and resolved in 4 of them. Levels of anti,double-stranded DNA antibodies decreased by a median of 47% in patients in the 4 mg/kg and 8 mg/kg dosage groups, with a 7.8% decrease in their IgG levels. These changes, together with a significant decrease in the frequency of circulating plasma cells, suggest a specific effect of tocilizumab on autoantibody-producing cells. Conclusion Although neutropenia may limit the maximum dosage of tocilizumab in patients with SLE, the observed clinical and serologic responses are promising and warrant further studies to establish the optimal dosing regimen and efficacy.

    Rituximab is effective in the treatment of refractory ophthalmic Wegener's granulomatosis

    ARTHRITIS & RHEUMATISM, Issue 5 2009
    Simon R. J. Taylor
    Objective To investigate the efficacy of rituximab in patients with refractory ophthalmic Wegener's granulomatosis (WG). Methods Data from 10 consecutive patients with refractory ophthalmic WG treated with rituximab were retrospectively reviewed. In all patients, the ophthalmic disease was driving treatment decisions, and disease activity had persisted despite standard immunosuppressive treatment. Patients had refractory scleritis (n = 3), orbital granulomas causing optic nerve compromise (n = 4), or a combination of both conditions (n = 3). All patients had been treated with at least 3 different immunosuppressive agents, and 5 patients had previously been treated with tumor necrosis factor , blockade. Rituximab was administered intravenously in 2 doses, 2 weeks apart, in combination with standard treatment. Disease activity was monitored clinically by an interdisciplinary approach, including disease activity scoring, immunodiagnostics, and magnetic resonance imaging, as well as by corresponding reductions in the required dose of conventional medication. Results A beneficial response to treatment with rituximab was seen in all 10 patients, including induction of clinical remission. In all patients, the peripheral blood B cell count fell to zero during treatment with rituximab. Titers of classic antineutrophil cytoplasmic antibodies fell in association with B cell counts, and this reduction was correlated with improved clinical findings. Conclusion In contrast to previous observations, this study showed that treatment with rituximab was associated with clinical improvement in patients with refractory ophthalmic WG. [source]


    Disconnect between inflammation and joint destruction after treatment with etanercept plus methotrexate: Results from the trial of etanercept and methotrexate with radiographic and patient outcomes

    ARTHRITIS & RHEUMATISM, Issue 10 2006
    Robert Landewé
    Objective To determine the relationship between disease activity and radiographic progression of joint destruction in patients with rheumatoid arthritis (RA) treated with methotrexate (MTX), those treated with etanercept, and those treated with the combination of MTX plus etanercept. Methods Baseline, 12-month, and 24-month data from the Trial of Etanercept and Methotrexate with Radiographic and Patient Outcomes database were analyzed. The dependent variable was the 1-year change in the modified Sharp/van der Heijde score (Sharp score); therefore, 2 interval changes per patient were available. Interval change in the Sharp score was modeled by time (years), treatment, disease activity, and the interaction (disease activity × treatment). Disease activity was reflected by the time-averaged Disease Activity Score (taDAS) and the time-averaged C-reactive protein (taCRP) level, which were calculated per 1-year interval. Generalized mixed linear modeling (GMLM) was used to adjust for within-patient correlation. Results GMLM confirmed a significant interaction between treatment and the taCRP level and taDAS with respect to the change in Sharp score (P = 0.012 and P = 0.03, respectively). In patients treated with MTX alone, radiographic progression increased with an increasing taCRP level or taDAS, although progression rates were low in patients whose disease was in remission and in those with low-to-moderate disease activity. This relationship was less clear in patients treated with etanercept and was absent in those who received combination therapy. Conclusion Combination therapy with MTX plus etanercept uncouples the classic relationship between disease activity and radiographic progression in patients with RA. [source]


    Systemic lupus erythematosus in a multiethnic US cohort: Clinical features, course, and outcome in patients with late-onset disease

    ARTHRITIS & RHEUMATISM, Issue 5 2006
    Ana M. Bertoli
    Objective To examine the clinical differences and the type and extent of organ damage in late- versus early-onset systemic lupus erythematosus (SLE). Methods A nested case,control study was performed in the context of LUMINA (LUpus in MInorities, NAture versus nurture), a large, longitudinal, multiethnic cohort. Patients who developed SLE at or after the age of 50 years were considered cases. Two controls (patients who developed SLE at age ,49 years) per case, matched for sex and disease duration, were randomly chosen. Selected baseline socioeconomic/demographic, behavioral, and psychological features, self-reported quality of life, and cumulative clinical data (clinical manifestations, laboratory data, disease activity, damage, and mortality) were compared between cases and controls. Multivariable analyses with late-onset lupus, damage accrual, and mortality as dependent variables were then performed. Results Two hundred seventeen patients were studied. Of them, 73 were cases. Cases were more likely to have neurologic involvement, arterial thrombotic events, osteoporosis, and hypertriglyceridemia, while renal involvement and anti-Sm antibodies were less frequent. Disease activity at baseline was lower among cases. Cases also exhibited more cardiovascular and ocular damage. Late-onset lupus was an independent predictor of damage accrual (t -test = 2.23, P = 0.028), any damage at last visit (odds ratio [OR] 23.32, 95% confidence interval [95% CI] 3.98,141.56) (P < 0.001), and mortality (OR 10.74, 95% CI 3.07,37.56) (P < 0.001). Conclusion Patients with late-onset lupus exhibit distinct clinical features. Although disease activity tends to be lower in these patients, they tend to accrue more damage and experience higher mortality than patients with early-onset lupus. These findings probably reflect the contribution exerted by other comorbid conditions in the overall impact of lupus in these patients. [source]
