The value of serum albumin in pretreatment assessment and monitoring of therapy in HIV/AIDS patients

HIV MEDICINE, Issue 6 2006
HO Olawumi
Objectives We sought to examine the utility of serum albumin measurement in staging AIDS and monitoring patients' response to therapy. Methods The possible importance of serum albumin measurement in assessing AIDS stage and in monitoring the response to highly active antiretroviral therapy using CD4 cell count and body weight as parameters was examined in 185 consecutive HIV-infected, therapy-naïve individuals who were recruited for antiretroviral therapy at the university of Ilorin Teaching Hospital. The regimen included lamivudine, stavudine and nevirapine. The diagnosis of AIDS was established through a combination of clinical features and HIV seropositivity using two different enzyme-linked immunosorbent assay techniques. Serum albumin level was determined by the Bromocresol green method, while the CD4 lymphocyte count was obtained using the Dynal T4 count method. Body weight was measured in kilograms with light clothes on. Results There were significant positive correlations between pretreatment albumin and both pretreatment CD4 cell count and pretreatment weight, and between post-treatment albumin and both post-treatment weight and post-treatment CD4 cell count up to a count of 700 cells/,L. There were also significant positive correlations between increase in serum albumin and both increase in body weight and duration of treatment. Conclusions We conclude that, in developing countries where many patients may not be able to afford to pay for CD4 cell counts and viral load tests, which are the traditional markers for HIV disease, serum albumin would be a very useful surrogate test for predicting severity of HIV infection and for clinical monitoring of response to antiretroviral therapy.

Serum albumin level predicts initial intravenous immunoglobulin treatment failure in Kawasaki disease

ACTA PAEDIATRICA, Issue 10 2010
Ho-Chang Kuo
Abstract Objectives:, Kawasaki disease (KD) is a systemic vasculitis primarily affecting children who are <5 years old. Intravenous immunoglobulin (IVIG) is the standard therapy for KD. However, many patients with KD still show poor response to initial IVIG treatment. This study was conducted to investigate the risk factors for initial IVIG treatment failure in KD. Methods:, Children who met KD diagnosis criteria and were admitted for IVIG treatment were retrospectively enrolled for analysis. Patients were divided into IVIG-responsive and IVIG-resistant groups. Initial laboratory data before IVIG treatment were collected for analysis. Results:, A total of 131 patients were enrolled during the study period. At 48 h after completion of initial IVIG treatment, 20 patients (15.3%) had an elevated body temperature. Univariate analysis showed that patients who had initial findings of high neutrophil count, abnormal liver function, low serum albumin level (,2.9 g/dL) and pericardial effusion were at risk for IVIG treatment failure. Multivariate analysis with a logistic regression procedure showed that serum albumin level was considered the independent predicting factor of IVIG resistance in patients with KD (p = 0.006, OR = 40, 95% CI: 52.8,562). There was no significant correlation between age, gender, fever duration before IVIG treatment, haemoglobin level, total leucocyte and platelet counts, C-reactive protein level, or sterile pyuria and initial IVIG treatment failure. The specificity and sensitivity for prediction of IVIG treatment failure in this study were 96% and 34%, respectively. Conclusion:, Pre-IVIG treatment serum albumin levels are a useful predictor of IVIG resistance in patients with KD. [source]

Cardiac troponins T and I in patients with end-stage renal disease: The relation with left ventricular mass and their prognostic value

CLINICAL CARDIOLOGY, Issue 12 2004
Adnan Abaci M.D. FESC
Abstract Background:Cardiac troponins are frequently elevated in patients with end-stage renal disease (ESRD) in the absence of acute myocardial ischemia. The cause and prognostic value of cardiac troponin elevations in such patients are controversial. Hypothesis:The aims of this study were (1) to define the incidence of cTnT and cTnI elevations in patients with ESRD, (2) to evaluate the relationship between troponin elevations and leftventricularmass index (LVMI), and (3) to evaluate the prognostic value of elevations in cTnT and cTnI prospectively. Methods:We included 129 patients with ESRD (71 men, age 44 ± 16 years) with no clinical evidence of coronary artery disease. All patients underwent cardiac examinations, including medical history, physical examination, electrocardiogram, andtransthoracic echocardiography. Left ventricular mass index was calculated and all patients were followed for 2 years. Results:The cTnT concentration was > 0.03,0.1 ng/ml in 27 (20.9%) and > 0.1 ng/ml in 27 (20.9%) of the 129 patients. The cTnI concentration was > 0.5 ng/ml in 31 (24%) of 129 patients. Multiple logistic regression analysis identified LVMI (p < 0.001), diabetes (p = 0.001), and serum albumin level (p= 0.009) as a significant independent predictor for elevated cTnT. Left ventricular mass index was the only significant independent predictor for elevated cTnI (p = 0.002). There were 25 (19.4%) deaths during follow-up. Multivariable analysis showed that elevation of cTnT and cTnI did not emerge as an independent predictor for death. Serum albumin level (p < 0.001) was the strongest predictor of mortality, followed by age (p = 0.002) and LVMI (p = 0.005). Conclusions:Cardiac troponin T and I related significantly to the LVMI. The increased serum concentration of cardiac troponins probably originates from the heart; however, they are not independent predictors for prognosis. [source]

Body composition and time course changes in regional distribution of fat and lean tissue in unselected cancer patients on palliative care,Correlations with food intake, metabolism, exercise capacity, and hormones

CANCER, Issue 10 2005
Marita Fouladiun M.D.
Abstract BACKGROUND Several investigations that yielded different results in terms of net changes in body composition of weight-losing cancer patients have been reported that employed a variety of methods based on fundamentally different technology. Most of those reports were cross-sectional, whereas to the authors' knowledge there is sparse information available on longitudinal follow-up measurements in relation to other independent methods for the assessment of metabolism and performance. METHODS For the current report, the authors evaluated time course changes in body composition (dual-energy X-ray absorptiometry) with measurements of whole body and regional distribution of fat and lean tissue in relation to food and dietary intake, host metabolism (indirect calorimetry), maximum exercise capacity (walking test), and circulating hormones in cancer patients who were receiving palliative care during 4,62 months of follow-up. The entire cohort comprised 311 patients, ages 68 years ± 3 years who were diagnosed with solid gastrointestinal tumors (84 colorectal tumors, 74 pancreatic tumors, 73 upper gastrointestinal tumors, 51 liver-biliary tumors, 3 breast tumors, 5 melanomas, and 21 other tumor types). RESULTS Decreased body weight was explained by loss of body fat, preferentially from the trunk, followed by leg tissue and arm tissue, respectively. Lean tissue (fat-free mass) was lost from arm tissue, whereas trunk and leg tissue compartments increased, all concomitant with declines in serum albumin, increased systemic inflammation (C-reactive protein, erythrocyte sedimentation rate), increased serum insulin, and elevated daily caloric intake; whereas serum insulin-like growth factor 1 (IGF-1), resting energy expenditure, and maximum exercise capacity remained unchanged in the same patients. Serum albumin levels (P < 0.001), whole body fat (P < 0.02), and caloric intake (P < 0.001) predicted survival, whereas lean tissue mass did not. Daily intake of fat and carbohydrate was more important for predicting survival than protein intake. Survival also was predicted by serum IGF-1, insulin, leptin, and ghrelin levels (P < 0.02 , P < 0.001). Serum insulin, leptin, and ghrelin (total) levels predicted body fat (P < 0.001), whereas IGF-1 and thyroid hormone levels (T3, free T3) predicted lean tissue mass (P < 0.01). Systemic inflammation primarily explained variation in lean tissue and secondarily explained loss in body fat. Depletion of lean arm tissue was related most to short survival compared with the depletion of lean leg and trunk tissue. CONCLUSIONS The current results demonstrated that body fat was lost more rapidly than lean tissue in progressive cancer cachexia, a phenomenon that was related highly to alterations in the levels of circulating classic hormones and food intake, including both caloric amount and diet composition. The results showed importance in the planning of efficient palliative treatment for cancer patients. Cancer 2005. © 2005 American Cancer Society. [source]

A randomized controlled trial of transcatheter arterial chemoembolization with lipiodol, doxorubicin and cisplatin versus intravenous doxorubicin for patients with unresectable hepatocellular carcinoma

EUROPEAN JOURNAL OF CANCER CARE, Issue 5 2009
M. MABED md, professor
Hepatocellular carcinoma (HCC) is a major and often therapeutically frustrating oncological problem. A total of 100 patients with unresectable HCC were recruited and randomized to be treated with either transcatheter arterial chemoembolization (TACE) or systemic chemotherapy. Fifty patients were treated with TACE using lipiodol, doxorubicin and cisplatin, while 50 patients were treated with systemic doxorubicin alone. Patients treated with TACE achieved a significantly higher response rate, with partial response achieved in 16 patients (32%) versus five patients (10%) in the chemotherapy arm (P = 0.007). A significantly more favourable tumour response to chemoembolization was found in patients with single lesions (P = 0.02), Child class A (P = 0.007), Okuda stage 1 (P = 0.005) and ,-feto protein less than 400 ng/mL (P < 0.001). The probability of tumour progression was significantly lower in cases treated with TACE where the median progression free survival was 32 weeks (range, 16,70 weeks) versus 26 weeks (range, 14,54 weeks) for patients treated with systemic chemotherapy (P = 0.03). However, the median overall survival did not differ significantly in cases treated with TACE (38 weeks) compared with those treated with chemotherapy (32 weeks) (P = 0.08), except for patients with serum albumin >3.3 g/dL (60 vs. 36 weeks; P = 0.003). Multivariate Cox regression analysis showed that a rise of serum albumin by 1 g/dL is associated with a decrease in the risk of death by 33% (95% confidence interval: 0.12,0.94, P = 0.038). Mortality in the chemoembolization arm was due to tumour progression in 18 patients (53%), liver failure in 11 patients (32%) and gastro intestinal tract (GIT) bleeding in 5 patients (15%). Mortality in the chemotherapy arm was due to tumour progression in 23 patients (64%), liver failure in 9 patients (25%) and GIT bleeding in 4 patients (11%). Treatment-related mortality was 4% in the TACE arm versus 0% in the chemotherapy arm. In conclusion, the overall survival benefits of TACE and systemic doxorubicin are similar for patients with unresectable HCC amenable to either treatment. It is crucial to optimize the benefit,risk ratio of TACE. In this setting, serum albumin level is a candidate marker for selection of cases who may benefit from this procedure. [source]

Restoration of innate host defense responses by oral supplementation of branched-chain amino acids in decompensated cirrhotic patients

HEPATOLOGY RESEARCH, Issue 12 2007
Ikuo Nakamura
Aim:, It has been reported that host defense responses, such as phagocytic function of neutrophils and natural killer (NK) cell activity of lymphocytes, are impaired in cirrhotic patients. The aim of the present study was to examine the effects of oral supplementation of branched-chain amino acids (BCAA) on host defense mechanisms in peripheral blood of patients with decompensated cirrhosis. Methods:, Ten patients with decompensated cirrhosis received 12 g BCAA daily for 3 months. Phagocytic function of neutrophils and NK activity of lymphocytes as well as serum albumin levels and Fisher's ratios were determined before and at 1 and 3 months of BCAA supplementation. For quantification of phagocytic function, fluorescent intensities of cells in the neutrophil region in the cytogram were determined by flow cytometry after incubation of whole blood with fluorescent microspheres. NK activity was estimated by 51Cr release assay using K-562 cell line as target cells. Results:, Phagocytic function of neutrophils was significantly improved by 3-month BCAA supplementation (P < 0.01). Thechanges of NK activity were also significant at 3 months of supplementation compared with before supplementation (P < 0.01). Fisher's ratios were significantly increased at 3 months of BCAA supplementation compared with those before oral supplementation (P < 0.05), although the changes of serum albumin level were not statistically significant. Conclusions:, BCAA oral supplementation improved phagocytic function of neutrophils and NK activity of lymphocytes in cirrhotic patients. BCAA supplementation may reduce the risk of bacterial and viral infection in patients with decompensated cirrhosis. [source]

Should we give thromboprophylaxis to patients with liver cirrhosis and coagulopathy?

HPB, Issue 6 2009
Marco Senzolo
Abstract Patients with liver cirrhosis are characterized by decreased synthesis of both pro- and anticoagulant factors, and recently there has been evidence of normal generation of thrombin resulting in a near normal haemostatic balance. Although it is generally recognized that bleeding is the most common clinical manifestation as a result of decreased platelet function and number, diminished clotting factors and excessive fibrinolysis, hypercoagulability may play an under recognized but important role in many aspects of chronic liver disease. In fact, they can encounter thrombotic complications such as portal vein thrombosis, occlusion of small intrahepatic vein branches and deep vein thrombosis (DVT). In particular, patients with cirrhosis appear to have a higher incidence of unprovoked DVT and pulmonary embolism (PE) compared with the general population. In dedicated studies, the incidence of DVT/PE ranges from 0.5% to 1.9%, similar to patients without comorbidities, but lower than patients with other chronic diseases (i.e, renal or heart disease). Surprisingly, standard coagulation laboratory parameters are not associated with a risk of developing DVT/PE; however, with multivariate analysis, serum albumin level was independently associated with the occurrence of thrombosis. Moreover, patients with chronic liver disease share the same risk factors as the general population for DVT/PE, and specifically, liver resection can unbalance the haemostatic equilibrium towards a hypercoagulable state. Current guidelines on antithrombotic prophylaxis do not specifically comment on the cirrhotic population as a result of the perceived risk of bleeding complications but the cirrhotic patient should not be considered as an auto-anticoagulated patient. Therefore, thromboprophylaxis should be recommended in patients with liver cirrhosis at least when exposed to high-risk conditions for thrombotic complications. Low molecular weight heparins (LWMHs) seem to be relatively safe in this group of patients; however, when important risk factors for bleeding are present, graduated compression stockings or intermittent pneumatic compression should be considered.

High Oxidative Stress Is Correlated with Frailty in Elderly Chinese

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 9 2009
I-Chien Wu MD
OBJECTIVES: To evaluate the relationship between oxidative stress and frailty in elderly people. DESIGN: Cross-sectional study. SETTING: Community and hospital-based outpatient clinic. PARTICIPANTS: Ninety participants aged 65 and older. MEASUREMENTS: Frailty status was determined according to the presence of weak handgrip strength, weight loss, slow walking speed, exhaustion, and low activity level and was classified as frail (,3 criteria), prefrail (1 or 2 criteria), or robust (0 criteria). An oxidative stress marker (serum 8-hydroxy-2,-deoxyguanosine, 8-OHdG), metabolic markers (body mass index, waist,hip ratio, serum lipids, glucose, and albumin), an inflammatory marker (serum high-sensitivity C-reactive protein, hs-CRP), demographic information, and comorbidities (diabetes mellitus, hypertension, congestive heart failure, osteoarthritis, overweight or obesity, impaired fasting plasma glucose, renal insufficiency, and depression) were assessed. RESULTS: Of the 90 participants, 21 (23.3%) were frail, 56 (62.2%) were prefrail, and 13 (14.4%) were robust. Frail subjects had higher median (range) serum 8-OHdG (2.5 ng/mL (1.5,6.2 ng/mL) vs 2.3 ng/mL (0.5,8.1 ng/mL) and 1.0 ng/mL (0.5,5.3 ng/mL)) and serum hs-CRP (2.5 mg/L (0.3,32.1 mg/L) vs 1.8 mg/L (0.3,50.5 mg/L) and 1.7 mg/L (0.3,4.0 mg/L)) levels, lower mean±standard deviation serum albumin levels (4.1±0.4 g/dL vs 4.4±0.4 g/dL and 4.6±0.2 g/dL) and higher mean waist,hip ratios (0.96±0.11 vs 0.91±0.07 and 0.89±0.05)) than prefrail and robust subjects, respectively (P<.05 for all). In multivariable regression analysis, high serum 8-OHdG level was still significantly associated with frailty after adjusting for age, smoking status, comorbidities, waist,hip ratio, serum albumin level, and hs-CRP level. CONCLUSION: High oxidative stress, characterized by high serum 8-OHdG level, was independently associated with frailty in the selected sample of elderly Chinese. [source]

Cognitive Impairment and Mortality in Older Primary Care Patients

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 7 2001
Timothy E. Stump MA
OBJECTIVE: To assess the impact of cognitive impairment on mortality in older primary care patients after controlling for confounding effects of demographic and comorbid chronic conditions. DESIGN: Prospective cohort study. SETTING: Academic primary care group practice. PARTICIPANTS: Three thousand nine hundred and fifty-seven patients age 60 and older who completed the Short Portable Mental Status Questionnaire (SPMSQ) during routine office visits. MEASUREMENTS: Cognitive impairment measured at baseline using the SPMSQ, demographics, problem drinking, history of smoking, clinical data (including weight, cholesterol level, and serum albumin), and comorbid chronic conditions collected at baseline; survival time measured during the 5 to 7 years after baseline. RESULTS: Eight hundred and eighty-six patients (22.4%) died during the 5 to 7 years of follow-up. Cognitive impairment was categorized as having no impairment (84.3%), mild impairment (10.5%), and moderate-to-severe impairment (5.2%) based on SPMSQ score. Chi-square tests revealed that patients with moderate-to-severe impairment were significantly more likely to die compared with patients with mild impairment (40.8% vs 21.5%) and those with no impairment (40.8% vs 21.4%). No significant difference in crude mortality was found between patients with no impairment and those with mild impairment. After analyzing time to death using the Kaplan-Meier method, patients with moderate-to-severe cognitive impairment were at increased risk of death compared with those with no or mild impairment (Log-rank ,2 = 55.5; P < .0001). Even in multivariable analyses using Cox proportional hazards to control for confounding factors, compared with those with no impairment, moderately-to-severely impaired patients had an increased risk of death, with a hazard ratio (HR) of 1.70. Increased risk of death was also associated with older age (HR = 1.03 for each year), a history of smoking (HR = 1.48), having a serum albumin level <3.5 g/L (HR = 1.29), and weighing less than 90% of the ideal body weight (HR = 1.98). Outpatient diagnoses associated with increased mortality risk were diabetes mellitus, coronary artery disease, congestive heart failure, cerebrovascular disease, cancer, anemia, and chronic obstructive pulmonary disease (HR range 1.36,1.67). Factors protective of mortality risk included female gender (HR = 0.67) and black race (HR = 0.73). CONCLUSIONS: Moderate-to-severe cognitive impairment is associated with an increased risk of mortality, even after controlling for confounding effects of demographic and clinical characteristics. Mild cognitive impairment is not associated with mortality risk, but a longer follow-up period may be necessary to identify this risk if it exists. [source]

Comparison of outcomes between patients with alcoholic cirrhosis and those with hepatitis C virus-related cirrhosis

JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 7 2009
Nobuyuki Toshikuni
Abstract Background and Aim:, The natural history of alcoholic cirrhosis, especially in Asian countries, has not been completely understood thus far. Methods:, We retrospectively compared the outcomes of compensated cirrhosis between Japanese alcoholic and hepatitis C virus (HCV)-infected patients. Results:, A total of 227 patients (75 alcoholic and 152 HCV-infected patients) with compensated cirrhosis were enrolled. The median follow-up period was 4.9 years. The cumulative rates of hepatocellular carcinoma (HCC) development were significantly lower in the alcoholic patients than in the HCV-infected patients (6.8% vs 50.3% at 10 years, P = 0.0003), while the cumulative rates of hepatic decompensation (37.4% vs 51.7% at 10 years) and survival (53.8% vs 47.4% at 10 years) did not significantly differ between the two groups (Kaplan-Meir analysis). The main causes of death were hepatic failure and non-hepatic diseases in the alcoholic patients and HCC and hepatic failure in the HCV-infected patients. Multivariate analyses using the Cox proportional hazard model revealed that the risk of HCC was lower in alcoholic cirrhosis than in HCV-related cirrhosis (hazard ratio (HR), 0.46), while the risk of hepatic decompensation and mortality was the same. Predictors of decreased survival were non-abstinence (HR, 2.53) in the alcoholic patients and low serum albumin level (1.58) in the HCV-infected patients. Conclusions:, Survival of patients with alcoholic cirrhosis was similar to that of patients with HCV-related cirrhosis. The risk of HCC development was lower in alcoholic cirrhosis than in HCV-related cirrhosis. Abstinence from alcohol was important for improving the survival of patients with alcoholic cirrhosis.

Prognostic factors in patients with small hepatocellular carcinoma treated by percutaneous ethanol injection

JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 11 2002
Hitoshi Kuriyama
Abstract Background: Percutaneous ethanol injection (PEI) has been widely performed and is now accepted as a viable alternative to hepatic resection in patients with small hepatocellular carcinomas (HCC). However, only a few extensive investigations have been conducted regarding the prognostic factors for HCC patients treated with PEI. Methods: We investigated the prognostic factors in 100 patients with small HCC who had undergone PEI. Univariate analysis and multivariate analysis with Cox's proportional hazards model were used to determine the factors potentially related to survival. For clinical application, a prognostic index was calculated based on the regression coefficients of the independent variables identified from the multivariate analysis. Results: Median survival time and 1, 3 and 5 year survival rates were 71 months and 100, 84 and 62%, respectively. Among the 15 potential prognostic variables investigated, only three variables, namely a serum albumin level ,,3.5 g/dL, the presence of tumor stain and a serum glutamic oxaloacetic transaminase level>,66 IU/L, were identified as factors independently associated with a shorter survival. A prognostic index based on the regression coefficients of these three factors was proposed to classify patients into three groups, those with a good (5 year survival rate 91%), intermediate (64%) and poor prognosis (22%). Conclusions: The results of the present study may be useful in predicting the survival of HCC patients treated with PEI and in the design and analysis of future clinical trials of PEI for HCC. © 2002 Blackwell Publishing Asia Pty Ltd [source]

Effects of hepatic blood inflow occlusion on liver regeneration following partial hepatectomy in an experimental model of cirrhosis

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 11 2000
X. -Y.
Background Hepatic blood inflow occlusion during hepatectomy may influence postoperative liver regeneration. The aim of this study was to investigate the influence of hepatic blood inflow occlusion on liver regeneration following partial hepatectomy in thioacetamide-induced cirrhotic rats. Methods Forty-three cirrhotic Wistar,Furth rats were randomly assigned to three groups. Rats in group 1 underwent 64 per cent hepatectomy alone, those in group 2 were subjected to 15 min hepatic blood inflow occlusion followed by 64 per cent hepatectomy, and animals in group 3 were subjected to 30 min inflow occlusion followed by 64 per cent hepatectomy. Liver function, 5-bromo-2,-deoxyuridine (BrdU) labelling index and percentage of initial liver weight on days 1, 2 and 7 posthepatectomy were assessed. Results Rats in groups 1 and 2 had a significantly higher serum albumin level and a markedly lower alanine aminotransferase level than animals in group 3 on day 1 posthepatectomy (P < 0·05). There was no significant difference in the serum level of total bilirubin of the three groups on days 1, 2 and 7. The BrdU labelling index was significantly higher in groups 1 and 2 than in group 3 animals on day 1 posthepatectomy (P < 0·01 and P < 0·05 respectively). Percentages of initial liver weight were similar in groups 1, 2 and 3 on days 1, 2 and 7 after hepatectomy. Conclusion Hepatic blood inflow occlusion for up to 30 min suppressed DNA synthesis and hepatocyte proliferation at an early posthepatectomy stage and consequently delayed recovery of liver function in cirrhotic rats. However, it did not affect restoration of liver mass or survival after 64 per cent hepatectomy. © 2000 British Journal of Surgery Society Ltd [source]

Treatment recommendations for chronic hepatitis B: An evaluation of current guidelines based on a natural history study in the United States,

HEPATOLOGY, Issue 4 2008
Myron John Tong
Current guidelines for treatment of chronic hepatitis B include hepatitis B e antigen (HBeAg) status, levels of hepatitis B virus (HBV) DNA, and serum alanine aminotransferase (ALT) values in the setting of either chronic hepatitis or cirrhosis. Based on findings from a prospective study of hepatitis B surface antigen (HBsAg)-positive patients, we determined whether these guidelines included patients who developed hepatocellular carcinoma (HCC) and who died of non-HCC liver-related complications. The criteria for treatment from four published guidelines were matched to a cohort of 369 HBsAg-positive patients enrolled in the study. During a mean follow-up of 84 months, 30 patients developed HCC and 37 died of non-HCC liver-related deaths. Using criteria for antiviral therapy as stated by the four guidelines, only 20%-60% of the patients who developed HCC, and 27%-70% of patients who died of non-HCC liver-related deaths would have been identified for antiviral therapy according to current treatment recommendations. If baseline serum albumin levels of 3.5 mg/dL or less or platelet counts of 130,000 mm3 or less were added to criteria from the four treatment guidelines, then 89%-100% of patients who died of non-HCC liver-related complications, and 96%-100% of patients who developed HCC would have been identified for antiviral therapy. In addition, if basal core promoter T1762/A1764 mutants and precore A1896 mutants also were included, then 100% of patients who developed HCC would have been identified for treatment. Conclusion: This retrospective analysis showed that the current treatment guidelines for chronic hepatitis B excluded patients who developed serious liver-related complications. (HEPATOLOGY 2008.)

Quality of life in chronic kidney disease: effects of treatment modality, depression, malnutrition and inflammation

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 4 2007
B. Kalender
Summary In the present study, our aim is to investigate the effects of the treatment modality, depression, malnutrition and inflammation on quality of life (QoL) in chronic kidney disease (CKD). Twenty-six patients with CKD on conservative management, 68 patients on haemodialysis (HD), 47 patients on continuous ambulatory peritoneal dialysis (CAPD) and 66 healthy controls were enrolled in the study. QoL was measured by means of the Short Form-36 (SF-36) and subscale scores were calculated. All patients were evaluated for the presence of depression using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I Disorders , Clinician Version. The severity of depression was evaluated by means of the Beck Depression Inventory (BDI). Serum C-reactive protein (CRP), ferritin, albumin, haemoglobin and haematocrit (Hct) levels were measured. All the SF-36 subscale scores were lower in the patient groups compared with control group. The SF-36 scores were higher and BDI scores were lower in the CAPD group than CKD and HD groups. In patients with depression, all SF-36 subscale scores were lower than that of the patients without depression. There was a significant negative correlation between all the SF-36 subscale scores and the BDI scores. There was a significant positive correlation between the SF-36 physical and total summary scores and the Hct value and serum albumin levels, but an inverse correlation between the SF-36 physical, mental and total summary scores and the serum CRP level in the HD patients. The authors suggest that the treatment modality, depression, malnutrition and inflammation have an important role on QoL in CKD. [source]

Gallbladder wall thickening in mononucleosis syndromes

JOURNAL OF CLINICAL ULTRASOUND, Issue 6 2001
Kaoru Yamada MD
Abstract Purpose We used sonography to measure gallbladder wall thickness in patients with mononucleosis syndromes and then evaluated laboratory data, spleen size, and clinical evolution to assess any relationship between gallbladder wall thickening (GBWT) and the severity of disease. Methods We retrospectively reviewed the medical records, sonograms, and sonographic reports of 39 patients who were diagnosed with mononucleosis syndromes on the basis of fever, tonsillopharyngitis, cervical adenopathy, hepatosplenomegaly, and lymphocytosis with atypical lymphocytes. All 39 were included in the study. The gallbladder wall thickness in each patient was sonographically determined. GBWT was defined as a wall thickness exceeding 3 mm. We assessed the laboratory data and clinical evolution in each patient, and the differences between patients with and without GBWT were statistically analyzed. Results Six patients (15%) had GBWT. The mean atypical lymphocyte count ± standard deviation (SD) in the patients with GBWT (1,830/,l ± 1,000/,l) was significantly higher than that in patients without GBWT (1,140/,l ± 660/,l; p < 0.05). The mean total serum protein and serum albumin levels in the patients with GBWT (6.6 mg/dl ± 0.7 mg/dl and 3.7 mg/dl ± 0.5 mg/dl, respectively) were significantly lower than those in patients without GBWT (7.3 mg/dl ± 0.4 mg/dl and 4.1 mg/dl ± 0.3 mg/dl, respectively; p < 0.05). The duration of hospitalization in the patients with GBWT (14 ± 8.5 days) was significantly higher than that in patients without GBWT (8 ± 3.5 days; p < 0.05). Conclusions GBWT in mononucleosis syndromes may be a sign of the severity of the illness and when present indicates the need to carefully monitor the clinical course. © 2001 John Wiley & Sons, Inc.

Outcome Analysis of Patients with Squamous Cell Carcinoma of the Head and Neck and Hepatitis C Virus,

THE LARYNGOSCOPE, Issue 10 2005
Jason Hunt MD
Abstract Objective/Hypothesis: Infection with the hepatitis C virus (HCV) is a global problem with over 170 million people infected. Recently, we have noticed that a large number of patients diagnosed with squamous cell carcinoma of the head and neck (SCCHN) have also been diagnosed with HCV. A review of the literature reveals little information concerning this patient population. The objective of this study was to compare the outcome of SCCHN patients who have been exposed to HCV with naïve SCCHN patients. Study Design: Retrospective chart review. Methods: A retrospective chart review from June 1991 through December 2002 was performed to identify patients diagnosed with SCCHN who were screened for HCV. Patients were stratified into two groups (HCV positive and HCV negative). Data were recorded on patients for status of disease at last clinic visit, pretreatment serum albumin and hematocrit levels, and RNA quantities of HCV. Statistical analysis was performed using paired t test to compare serum albumin and hematocrit levels. Kaplan-Meier survival curves were used to compare outcomes. The log-rank test was used to determine significance. Cox regression was used to examine the association of prognostic predictor variables with overall survival and disease-free survival. Results: There was no difference noted in 5 year survival between hepatitis C positive and hepatitis C negative groups in overall outcomes (66.7% vs. 67.9%, P = 1.000) or 5 year disease-free survival (90.5% vs. 80.8%, P = .514). The two groups, HCV positive versus HCV negative, also had similar serum albumin levels (3.62 g/dL vs. 3.72 g/dL, P = .37) as well as serum hematocrit levels (42.9% vs. 41.0%, P = .12). Serum levels of hepatitis C RNA were obtained in seven patients, with only one being undetectable. The only prognostic predictor variable that was significantly associated with overall survival was age. None of the predictor variables were significantly associated with disease-free survival. Conclusion: Co-infection with HCV, although prevalent in the Veterans Administration Hospital population, did not affect patient outcome as defined by disease-free survival. Patients who were seropositive for HCV had comparable serum albumin levels as well as serum hematocrit when compared with HCV negative patients. [source]

Clinical evaluation of plasma free phenytoin measurement and factors influencing its protein binding

Abstract The relationship between free phenytoin concentrations and clinical responses, and the factors influencing protein binding of phenytoin were investigated. A total of 119 plasma samples from 70 patients treated orally with phenytoin were analysed. The mean free phenytoin concentration was significantly higher in the patients who received phenytoin monotherapy and were classified as having a complete response (1.25 ± 1.09 µg/ml) than that in the partial response group (0.59 ± 0.07 µg/ml), whereas the mean total concentrations were not significantly different between the two groups. Samples were divided into three groups based on the free fraction of phenytoin, i.e. low, <5%; medium, 5%,10%; high, >10%. The mean age (55.3 ± 10.9 years) was significantly higher in the high group than in the low (42.7 ± 21.2 years) and medium (42.8 ± 16.0 years) groups. The mean creatinine clearance (CLcr) (55.3 ± 10.9 ml/min) and serum albumin concentration (3.30 ± 1.25 g/dl) were significantly lower in the high group than the low (88.3 ± 29.0 ml/min and 4.08 ± 0.50 g/dl, respectively) and medium (95.0 ± 32.8 ml/min and 3.95 ± 0.92 g/dl, respectively) groups. These results suggest that the free phenytoin concentration, rather than the total concentration, is more useful for monitoring antiepileptic effects in patients receiving phenytoin monotherapy. It was also found that the free phenytoin fraction was significantly influenced by aging, CLcr and serum albumin levels. Copyright © 2005 John Wiley & Sons, Ltd. [source]
