    Childhood Psoriasis: A Clinical Review of 1262 Cases

    PEDIATRIC DERMATOLOGY, Issue 3 2001
    Anne Morris M.B., B.S.
    A total of 1262 patients seen consecutively in the dermatology department of the Royal Alexandra Hospital for Children, Sydney, Australia, between 1981 and 1995 are described and classified according to the pattern of psoriasis at the time of presentation. Additional information recorded included family history, facial involvement, and history of a psoriatic type of diaper rash in infancy. The ages of the children ranged from 1 month to 15 years. There was an equal gender distribution and a high rate of positive family history at 71%. Twenty-six percent of children had a history of a psoriatic diaper rash and facial involvement occurred in 38% of children. Plaque psoriasis was the most common type overall, affecting 430 patients (34%). Three hundred forty-five children were less than 2 years of age, and this is the largest series of children with psoriasis in this age group presented to date. An entity defined by us as psoriatic diaper rash with dissemination was the most common type of psoriasis in the less than 2-year age group, affecting 155 (45%) patients. This large series offers information on the manifestations of psoriasis in childhood, but is particularly useful in examining the previously less well-described infant age group. The classification used is proposed as a practical way to describe psoriasis in children, particularly with respect to future descriptive studies. [source]


    Adalimumab for treatment of moderate to severe psoriasis and psoriatic arthritis

    DERMATOLOGIC THERAPY, Issue 2008
    M. R. Bongiorno
    ABSTRACT: Psoriasis and psoriatic arthritis are common diseases associated with considerable morbidity and disability. Their pathophysiology comprises similar processes leading to inflammation of skin, entheses, and joints. Although traditional systemic agents can be effective, their use may be limited by lack of efficacy and concerns regarding adverse effects. The objective of this study was to assess the efficacy and safety of adalimumab, a fully human antitumor necrosis factor (anti-TNF) monoclonal antibody, over 16 weeks. The present authors report their personal experience in 15 patients with severe plaque psoriasis and psoriatic arthritis, refractory to other treatments, in which a decisive regression of joint/skin involvement was obtained. Psoriasis and psoriatic arthritis are chronic inflammatory disorders resulting from a combination of genetic and environmental factors. [source]


    Common polymorphisms in the interleukin-22 gene are not associated with chronic plaque psoriasis

    EXPERIMENTAL DERMATOLOGY, Issue 9 2009
    Wolfgang Weger
    Abstract Background:, Psoriasis is a chronic inflammatory skin disease. Among other cytokines, interleukin 22 (IL-22) has been implicated in the pathogenesis of chronic plaque psoriasis. The purpose of this study was to investigate a hypothesized association between common IL-22 gene polymorphisms and chronic plaque psoriasis. Methods:, Genotypes of 10 common polymorphisms of the IL-22 gene were determined by fluorogenic 5, exonuclease assays (TaqMan) in 475 patients with chronic plaque psoriasis and 252 controls. Results:, Two blocks of high linkage disequilibrium, formed by eight polymorphisms upstream of exon 5 (rs2227485, rs2227491, rs2046068, rs1179251, rs1012356, rs2227501, rs2227503, rs976748) and two polymorphisms in the 3, near gene region (rs1182844, rs1179246), were observed within the IL-22 gene. Neither single polymorphisms nor haplotypes were significantly associated with the presence or clinical features of chronic plaque psoriasis (P > 0.05). Conclusions:, Our data suggest that the investigated IL-22 gene polymorphisms are unlikely major risk factors for chronic plaque psoriasis. [source]


    A comparison between BSA, PASI, PLASI and SAPASI as measures of disease severity and improvement by therapy in patients with psoriasis

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 10 2008
    Tilo Henseler PhD
    Background, This study investigates four measures of disease severity in patients with psoriasis, both before and after therapy. Methods, Data records were analyzed from 33 patients with moderate-to-severe chronic plaque psoriasis who were treated with efalizumab, 1 mg/kg/week subcutaneously, for 12 weeks. Four measures of disease severity were used: body surface area (BSA), psoriasis area and severity index (PASI), psoriasis log-based area and severity index (PLASI) and self-administered PASI (SAPASI). Results, At the end of the 12-week therapy, the mean percent improvement shown by each measure varied considerably, ranging from 48.6% (PASI) to 70.6% (SAPASI). PASI and PLASI were the most comparable (67.3% and 66.5%). These differences were smaller when a dermatologist's opinion about the improvement was taken into account, for example "very good improvement" ranged from mean percent improvement of 63.8% (BSA) to 83.8% (PASI). The correlation between all measures revealed a high level of significance (P, 10,5). Conclusions, Comparing the slopes and intercepts of the regression lines revealed PLASI as the most reliable measure for the severity and therapeutic improvement in patients with moderate-to-severe chronic plaque psoriasis. PLASI proved to be a marginally more accurate than PASI, and much more accurate than SAPASI and BSA. The superiority of PLASI may be a result of the logarithmic scale of the affected skin surface.

    Safety of efalizumab in adults with chronic moderate to severe plaque psoriasis: A phase IIIb, randomized, controlled trial

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 5 2006
    Kim A. Papp MD
    Background, To provide safety data for efalizumab, a recombinant humanized monoclonal IgG1 antibody, in adults with chronic plaque psoriasis. Methods, A 12-week, Phase IIIb, randomized, double-blind, parallel-group, placebo-controlled trial. At 58 study sites in the USA and Canada, 686 patients with moderate to severe chronic plaque psoriasis received an initial conditioning dose of efalizumab 0.7 mg/kg subcutaneously (SC) followed by either 11 weekly doses of efalizumab 1 mg/kg SC or matching placebo. Main outcome measures were safety and tolerability outcomes (primary) and efficacy outcomes (secondary). Results, During 12 weeks of therapy with efalizumab or placebo, the incidence of clinical adverse events was 82.2% and 72.9%, respectively; the incidence of serious adverse events was 1.8% and 3.4%, respectively; and the incidence of nonserious adverse events leading to withdrawal was 1.8% and 1.7%, respectively. In the efalizumab group, there were no clinically significant changes in vital signs or laboratory parameters and no evidence of end-organ toxicities. A significantly higher proportion of patients receiving efalizumab than those receiving placebo achieved , 75% improvement in the Psoriasis Area and Severity Index (PASI) (P < 0.001), , 50% improvement in PASI (P < 0.001), and a static Physician's Global Assessment rating of Minimal or Clear (P < 0.001). The mean improvement in the Psoriasis Symptom Assessment was significantly greater in the efalizumab group (P < 0.001). Conclusions, Efalizumab treatment SC for 12 weeks was safe, well tolerated, and effective in patients with moderate to severe chronic plaque psoriasis. [source]


    Effectiveness of kukui nut oil as a topical treatment for psoriasis

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 8 2005
    Amy C. Brown PhD
    Background, No cure for psoriasis exists for the 1,3% of the American population who suffer from it; however, anecdotal reports from patients with psoriasis visiting Hawaii who purchased kukui nut oil, claim it helped reduce the severity of their lesions. Objective, This pilot study was a double-blind, placebo-controlled clinical trial to determine the effectiveness of kukui nut oil as a topical treatment for psoriasis. Methods, Thirty adult subjects (18,78 year) were recruited from the community for a 12-week randomized, double-blind, placebo-controlled pilot study. Subjects were previously diagnosed with mild, stable plaque psoriasis (less than 15% of total body surface area [TBSA]) and agreed to abstain from other treatments during the course of the study. Following a 4-week washout period the subjects were randomized into a treatment group (15 subjects applying kukui nut oil) or a control group (15 applying the mineral oil placebo). Patients were seen every 2 weeks (seven visits at 0, 2, 4, 6, 8, 10, and 12 weeks) by a dermatological nurse practitioner under the general supervision of a board certified dermatologist. Measurable outcomes included evaluation of one targeted lesion and of the overall severity of their psoriasis using clinical evaluation, Psoriasis Area and Sensitivity Index (PASI), Global Severity of Psoriasis Scale, and photographs. Each patient also evaluated their own lesions daily using the Global Severity of Psoriasis Scale, and noted any side-effects or other treatments used. Results, Although both groups improved, we found no significant difference between the treatment (kukui nut oil) and the placebo (mineral oil) among the 24 out of 30 subjects (80%) who completed the study. No side-effects or adverse events were reported. Conclusion, Kukui nut oil did not significantly reduce symptoms of psoriasis; however, this was a small pilot study, and the use of this oil cannot be dismissed without using a larger study population of patients with psoriasis.

    Pilot trial: Pioglitazone versus placebo in patients with plaque psoriasis (the P6)

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 4 2005
    Nusrat Shafiq MD
    Background, Disordered differentiation and hyperproliferation of keratinocytes with inflammation are the hallmarks of psoriasis. Ligand activation of peroxisome proliferator receptor-, (a class of nuclear receptors) by thiazolidinediones can normalize the histologic features of psoriasis. Method, In a 10-week, double-blind, randomized, placebo-controlled, parallel-group study, 70 patients with moderate to severe psoriasis received one of the following treatments: pioglitazone 15 mg, pioglitazone 30 mg or placebo. Efficacy was evaluated by observing the change in the psoriasis area and severity index (PASI) after 10 weeks of treatment. Results, There was a dose-dependent improvement in psoriasis. Median PASI scores at the end of 10 weeks were significantly reduced in the pioglitazone treatment groups as compared to the placebo-treated group. The psoriasis lesions cleared in more than 40% of patients treated with pioglitazone as compared to 12.5% of those with placebo. The percentage reduction in mean PASI scores was 21.6%, 41.1% and 47.5% in the placebo, pioglitazone 15 mg, and 30 mg groups, respectively. No serious adverse events were detected. Conclusion, This is the first report from a controlled trial demonstrating that pioglitazone could be considered as an efficacious and safe agent for the treatment of plaque psoriasis. The optimum dose and duration of pioglitazone therapy remain to be determined. [source]


    Rapid response to infliximab in severe pustular psoriasis, von Zumbusch type

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 7 2002
    Meggan R. Newland MD
    Tumor necrosis factor-alpha (TNF-,) is a chemokine secreted by T cells which is thought to play a critical role in the pathophysiology of psoriasis. The monoclonal antibody, infliximab, complexes with TNF-,, rendering it inactive. A recent clinical trial has reported the clinical benefit and safety of infliximab in moderate to severe plaque psoriasis. We report a case of rapid response and clinical benefit using infliximab in severe pustular psoriasis of von Zumbusch. [source]


    Cost-effectiveness of psoriasis therapy with etanercept in Germany

    JOURNAL DER DEUTSCHEN DERMATOLOGISCHEN GESELLSCHAFT, Issue 9 2007
    Tatjana Heinen-Kammerer
    Summary Background: We estimated the cost-effectiveness of intermittent therapy with etanercept in patients with moderate-to-severe plaque-type psoriasis in comparison to non-systemic therapy in Germany. Patients and Methods: We performed a cost-utility analysis using the endpoint costs per quality-adjusted life year gained (costs/QALY). For this purpose, we adapted a UK-based Markov model by means of resource use data that we derived from a German cost study. Efficacy data, information on frequency of adverse events and changes in quality of life were derived from three pooled clinical trials. We extrapolated the further course of the disease and its treatment over a 10 year course. Results: For patients with an initial Psoriasis Area and Severity Index (PASI) > 10 and a Dermatology Life Quality Index (DLQI) > 10 the incremental cost-effectiveness ratio (ICER) for etanercept compared to non-systemic therapy was 45,491 ,/QALY. For patients with PASI and DLQI > 15 costs/QALY were 32,058 , and among patients with severe plaque psoriasis (DLQI and PASI > 20) 18,154 , . Conclusions: According to internationally accepted levels of cost-effectiveness thresholds, the intermittent treatment of (moderate to) severe plaque-type psoriasis with etanercept is a cost-effective measure within the German healthcare system.

    Anti,tumour necrosis factor-, therapy increases body weight in patients with chronic plaque psoriasis: a retrospective cohort study

    JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 3 2008
    P Gisondi
    Abstract Background, Chronic plaque psoriasis is associated with overweight or obesity. Anti,tumour necrosis factor-, (anti-TNF-,) treatments are now frequently used in psoriasis management. TNF-, is deeply involved in body weight homeostasis, which may be affected by TNF-,,targeted therapy. Objective, To investigate whether anti-TNF-, treatments is associated with changes in body weight in patients with chronic plaque psoriasis. Methods, We performed a retrospective controlled analysis comparing the variations in body weight and body mass index (BMI) in three closed cohorts of psoriatic patients during a 6-month treatment with etanercept (N = 58), infliximab (N = 40) or methotrexate (N = 43). Results, We observed a body weight increment of 1.5 ± 2.7 kg (mean ± SD; P = 0.0002) and 2.5 ± 3.3 kg (P = 0.004) in patients treated with etanercept and infliximab, respectively. In contrast, a non-significant change (0.6 ± 1.4 kg; P = 0.4) was measured in patients treated with methotrexate. The BMI increased with 0.5 ± 0.5 (P = 0.01) and 0.8 ± 1 (P = 0.003) points in patients treated with etanercept and infliximab, respectively, whereas it did not change (< 0.2 ± 0.5; P = 0.06) in patients treated with methotrexate. About one fourth of patients experienced a 4- to 10-kg weight gain. Differences in body weight variations among patients treated with anti-TNF-, therapies and methotrexate were statistically significant (P = 0.0005). We could not identify clinical parameters predicting this phenomenon. Conclusions, Patients with psoriasis treated with long-term anti-TNF-, therapies may manifest a body weight gain. This effect should be taken into account in the global approach to patients with psoriasis. [source]

    Methotrexate in psoriasis: 26 years' experience with low-dose long-term treatment

    JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 5 2000
    U-F. Haustein
    Abstract Objective,To evaluate the efficacy, safety and side-effects of methotrexate (MTX) in psoriasis. Design,A 26-year retrospective study. Setting,Department of Dermatology, Leipzig University, Leipzig, Germany. Patients,One hundred and fifty-seven patients with extensive plaque psoriasis, erythrodermic, pustular and arthropathic forms, were treated with low-dose methotrexate (15,20 mg maximum weekly dosage [Weinstein schedule]), the majority for long-term periods. The mean cumulative dose was 3394 mg, the mean duration 237 weeks. Results,The effect of MTX treatment was good in 76%, moderate in 18% and poor in 6% of subjects; 61% experienced side-effects, most frequently due to liver function abnormalities, bone marrow suppression, nausea, gastric complaints and hair loss. In 20% of cases the subjects were forced to discontinue therapy; 9% refused therapy due to physical and psychological discomfort, 2% wanted to become pregnant, 16% were lost to follow-up, 6% died from multimorbidity and old age. Three subjects (2%) developed cancer of the lung, breast or cervix uteri, possibly in relation to long-term MTX treatment. Altogether there were no deaths or life-threatening side-effects attributable to MTX treatment, and no cases of progressive liver cirrhosis apart from two extensive skin necroses due to overdosage (misunderstanding, suicidal attempt) that were treated successfully with citrovorum factor. Conclusion,Low-dose MTX (<15,20 mg/week) is an effective therapy for extensive and severe forms of psoriasis if patients are selected carefully and monitored regularly, particularly with respect to liver and bone marrow toxicity. This helps to reduce severe side-effects even during long-term treatment. Drug interactions must be avoided. MTX therapy according to the guidelines is relatively safe and still has a place in the systemic treatment of psoriasis with 40 years of experience and an acceptable safety record. [source]


    Vitamin D production in psoriasis patients increases less with narrowband than with broadband ultraviolet B phototherapy

    PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE, Issue 3 2009
    Amra Osmancevic
    Background: Phototherapy of psoriasis is an effective treatment. In addition to standard broadband ultraviolet radiation B (UVB), (280,320 nm), narrowband phototherapy (NBUVB) (monochromatic UV between 311 and 312 nm) has become an important treatment for psoriasis. The same wavelength range of UVB (290,315 nm) induces synthesis of vitamin D. The aim was to compare the effect of broadband with NBUVB therapy on vitamin D synthesis in patients with psoriasis. Methods: Sixty-eight Caucasian patients (17 women and 51 men) mean age 54.1 ± 16.0 years, with active plaque psoriasis, were treated with broadband UVB (n=26) or NBUVB (n=42) two to three times/week for 8,12 weeks. The serum concentrations of 25-hydroxyvitamin D (25(OH)D3), 1,25-dihydroxyvitamin D (1,25(OH)2D3), intact parathyroid hormone (PTH), calcium and creatinine were measured before the first exposure and after the last dose of radiation. Results: In broadband UVB treated patients, 25(OH)D3 increased from 37.9 ± 16.9 to 69.4 ± 19.7 ng/ml (P<0.0001) and in patients treated with NBUVB from 34.8 ± 11.9 to 55.3 ± 17.6 ng/ml (P<0.0001) and P=0.008 between the treatment groups. PTH decreased on broadband UVB (P<0.05). The serum concentrations of 1,25(OH)2D3, calcium or creatinine remained unaltered. Conclusion: Serum 25(OH)D3 in psoriasis patients increased less with NBUVB than with broadband UVB phototherapy. Psoriasis improved on both regimens. [source]

    Osteoporosis guideline A new guideline on the management of osteoporosis in men over 50 and post-menopausal women has been published by the National Osteoporosis Guideline Group (www.shef.ac.uk/NOGG), a group of organisations representing health professionals and patients, with funding from several pharmaceutical companies. The guideline recommends using the FRAX tool (www.shef.ac.uk/FRAX) to assess the 10-year fracture risk in individuals with risk factors to facilitate targeting DXA scans to measure bone mineral density. Patients who have already sustained a fragility fracture should be treated without risk assessment. Treatment recommendations are similar to those published in draft NICE guidance on primary and secondary prevention, selecting alendronate as the drug of first choice for most patients. Efalizumab efficacy A multicentred postapproval trial has demonstrated long-term efficacy and a favourable safety profile for efalizumab (Raptiva) in moderate to severe chronic plaque psoriasis. The CONTROL II study, presented in September at the 17th EADV congress in Paris, was conducted at 170 sites in 18 European countries and involved 1255 patients who had failed to respond to traditional systemic therapies. In this non-blinded study, 68 per cent of participants achieved the primary efficacy end-point and showed improvement within the first 12 weeks; control was maintained in responding patients who continued treatment. Adverse effects were graded as mild or moderate and similar to those reported in earlier studies. There was no evidence of an increase in malignancies or infections. New oral anticoagulant Rivaroxaban (Xarelto), an oral factor Xa inhibitor, has been introduced for the prevention of venous thrombo-embolism in patients undergoing elective hip or knee replacement surgery. Compared with the low molecular weight heparin enoxaparin (Clexane), rivaroxaban has been shown to reduce the risk of venous thrombosis by 70 per cent after hip replacement and by 49 per cent after knee replacement; the risk of bleeding was similar. At the recommended dose of 10mg once daily, prophylaxis after hip surgery lasts five weeks and costs £157; prophylaxis after knee surgery lasts two weeks and costs £63. New products UCB Pharma has introduced lacosamide (Vimpat) as adjunctive treatment of partial-onset epilepsy with or without secondary generalisation in patients aged 16 and over. A month's treatment at the recommended maintenance dose of 100-200mg twice daily costs approximately £73-£140. A new non-nucleoside reverse transcriptase inhibitor (NNRI) is available for the treatment of HIV-1 infection in combination with a boosted protease inhibitor (PI) and other antiretrovirals in treatment-experienced adults. Etravirine (Intelence) costs approximately £320 for one month's treatment at the recommended dose of 200mg twice daily. Voltarol Pain-Eze (diclofenac) 12.5mg tablets are now available without prescription; a pack of 18 tablets costs £5.99. Atypicals and EPS risk Atypical antipsychotics are not associated with a significantly lower risk of extra-pyramidal symptoms than first-generation agents such as perphenazine (Fentazin), a new analysis of the CATIE study has shown (Br J Psychiatry 2008;193:279,88). CATIE was a large trial comparing the efficacy and safety of antipsychotics in the treatment of schizophrenia in which perphenazine was a representative first-generation agent (Am J Psychiatry 2006;163:611,22). This analysis found no differences in the risk of parkinsonism, dystonia, akathisia or tardive dyskinesia between perphenazine and the newer antipsychotics; use of antiparkinsonian medication was higher with risperidone and lower with quetiapine (Seroquel). Mental health website A new website offering information about mental illnesses and drug treatment has been launched by the United Kingdom Psychiatric Pharmacy Group (UKPPG), the College of Mental Health Pharmacists (CMHP), the Pharmaceutical Schizo-phrenia Initiative (PSI) and the National Institute for Mental Health in England (NIMHE). www.choiceandmedication.org.uk includes information about 17 mental illnesses and a large number of drug treatments. It offers links to other sites offering information and downloadable leaflets, help to identify the local mental health trust and downloadable charts comparing treatments for each indication.

    Higher risk of CV events in aspirin resistance More than one in four patients may have aspirin resistance, a new metaanalysis shows, and they face a four-to sixfold increased risk of a major cardiovascular event or death compared with aspirin-sensitive patients taking low-dose aspirin (BMJ online: 17 Jan 2008; doi:10. 1136/bmj.39430.529549.BE). The analysis included 20 studies involving a total of 2930 patients with cardiovascular disease. Of these, 28 per cent were defined as having aspirin resistance (according to the various definitions in each study). Compared with aspirin-sensitive patients, the odds ratio of any cardiovascular event or acute coronary syndrome was about 4 and the odds ratio of death was 6. Aspirin-resistant patients did not benefit from other antiplatelet treatment. ADOPT: rosiglitazone fracture risk in women A new analysis of the ADOPT trial (N Engl J Med 2006;355: 2427-43) has found that the risk of fractures during treatment with rosiglitazone (Avandia) is approximately twice as high as with metformin or glibenclamide, but mainly in women (Diabetes Care online: 25 Jan 2008; doi: 10.2337/dc07-2270). The study found a significant difference in risk between the drugs only for women, with a cumulative incidence of 15.1 per cent with rosiglitazone, 7.3 per cent with metformin and 7.7 per cent with glibenclamide after five years. No risk factors were identified although the incidence of fractures was higher among postmenopausal than premenopausal women. New from NICE Infliximab for the treatment of adults with psoriasis. Technology Appraisal Guidance No. 134, Jan 2008 Infliximab (Remicade), a monoclonal antibody against TNF-alpha, should be an option for treating very severe plaque psoriasis in adults, NICE recommends. Using its fast-track single technology appraisal procedure, NICE concluded that infliximab should be considered when standard therapies,methotrexate or ciclosporin (Neoral), or PUVA , have failed or are unsuitable. The criteria for disease severity are defined by the Psoriasis Area Severity Index (PASI) score (,20) and the Dermatology Life Quality Index (DLQI) score (>18). Treatment response is also defined by these measures and infliximab should be continued for longer than 10 weeks only when predefined thresholds are met. Infliximab costs an average of £11 750 annually. In 2006, NICE recommended etanercept (Enbrel) and efalizumab (Raptiva) for patients with severe psoriasis (PASI ,10 and DLQI >10). Commons committee wants tougher targets Most GPs get full QOF points for medicines management even though there is inexplicably large variation in good prescribing practice between PCTs, the Public Accounts Select Committee points out in its latest report, Prescribing Costs in Primary Care. The Committee wants to see tougher QOF targets among several initiatives to reduce prescribing costs. Although most publicity centred on its endorsement of the National Audit Office claim that GPs could save £200 million by prescribing lower-cost drugs, the report contains some more far-reaching proposals. GPs should prescribe generic alternatives within a therapeutic category, so when a brand is not available generically, eg Lipitor, a different drug that is, eg simvastatin, should be used when clinically appropriate. Further, this form of substitution should be rewarded via QOF targets. There should be greater uniformity in the appearance, labelling and packaging of generic and branded equivalents. The Department of Health should consider raising awareness of the value of medicines by printing the cost on packaging, and to reduce the £100 million wasted annually in dumped medicines, it should investigate which drugs aren't used and why patients won't take them. Strategic health authorities should work with the National Prescribing Centre to develop more prescribing indicators with which to measure PCT performance and support PCTs to promulgate best practice. They should also collaborate on promoting joint primary-secondary care formularies and increase the consistency of prescribing, not only between hospital specialists and GPs but also between PCTs. To monitor the influence of the pharmaceutical industry, PCTs should keep a record of gifts and hospitality and publish a register. Questions to ask about mental health treatment The Department of Health has published a booklet designed to raise awareness of medicines management issues affecting people using mental health services and their carers, and professionals in the health and social services. Although one aim of Medicines Management: Everybody's Business is to empower people with mental health problems to ask about their medication, its formal style is better suited to staff who need to improve their person-centred approach to care. It covers what information people should expect and what questions to ask when drug treatment is being considered, what to expect at review and issues to consider when contemplating stopping treatment. Copies can be downloaded at www.dh.gov.uk. Consider statins for all patients with diabetes Treatment with a statin should be considered for all patients with diabetes unless their risk is low, say the authors of a new study (Lancet 2008;371:117-25). Their meta-analysis of 14 randomised trials involving 18 686 people with diabetes and an average follow-up of 4.3 years found that statins reduced vascular events and vascular mortality as much as in nondiabetic populations. The overall benefit was 42 fewer major events per 1000 people treated for five years. This was independent of a history of vascular disease or other baseline characteristics. No evidence for OTC cough medicines There is no evidence that over-the-counter cough medicines for adults and children are effective in relieving acute cough, a new Cochrane review has concluded (Cochrane Database of Systematic Reviews 2008, Issue 1). The review of 17 randomised trials involving 2876 adults and eight involving 616 children reported conflicting findings of uncertain clinical relevance. The trials were heterogeneous and of low quality. Copyright © 2008 Wiley Interface Ltd [source]


    Adalimumab in Japanese patients with moderate to severe chronic plaque psoriasis: Efficacy and safety results from a Phase II/III randomized controlled study

    THE JOURNAL OF DERMATOLOGY, Issue 4 2010
    Akihiko ASAHINA
    Abstract Incidence of psoriasis vulgaris in Asians is estimated at 0.05,0.3%. Studies in North America and Europe demonstrated that adalimumab, a fully human, recombinant, immunoglobulin G1 monoclonal antibody, was efficacious and well-tolerated in patients with chronic plaque psoriasis. This 24-week, placebo-controlled study evaluated the efficacy and safety of three different dosing regimens of adalimumab in Japanese patients with moderate to severe chronic plaque psoriasis (n = 169). Patients were randomized to receive adalimumab 40 mg every other week (eow), adalimumab 80-mg loading dose at week 0 followed by adalimumab 40 mg eow starting at week 2, adalimumab 80 mg eow, or placebo eow given as s.c. injections. The primary efficacy endpoint was the percentage of patients achieving a 75% or greater improvement in Psoriasis Area and Severity Index (PASI 75) score at week 16. At week 16, PASI 75 response rates were significantly greater for all three adalimumab groups (40 mg eow: 57.9%, P < 0.001; 40 mg eow plus loading dose: 62.8%, P < 0.001; 80 mg eow: 81.0%, P < 0.001) versus placebo (4.3%). As early as week 4, the 40-mg eow plus loading dose and 80-mg eow groups achieved significantly greater PASI 75 response rates compared with placebo. Injection-site reactions and hepatic events occurred in greater percentages of adalimumab-treated patients compared with placebo. Adalimumab therapy demonstrated efficacy and safety at all three dosage regimens. Rapid response rate in patients receiving 40 mg eow plus loading dose supports using an 80-mg loading dose in the treatment of psoriasis. [source]


    Psoriasis and the eye: Prevalence of eye disease in Singaporean Asian patients with psoriasis

    THE JOURNAL OF DERMATOLOGY, Issue 12 2007
    Nisha S. CHANDRAN
    ABSTRACT There is little published data on the incidence of eye disease in Asian patients with psoriasis. We determined the frequency of ocular complications in Singaporean Asian patients with chronic plaque psoriasis and related these to extent and severity of psoriasis, family history, treatment and presence of arthritis. A cross-sectional prevalence investigation was carried out in 100 patients who received a comprehensive eye examination. Psoriasis extent and severity was graded by the Lattice System Physician's Global Assessment (LS-PGA). Two patients (four eyes) had uveitis, one of whom had psoriatic arthritis (2% incidence). Presence or absence of uveitis correlated with mean LS-PGA scores. Sixty-three patients had cataract unrelated to previous steroid or phototherapy treatment; in younger (<50 years) patients they were commoner than in those with higher (>5) LS-PGA scores. Three eyes in two patients (2% prevalence) had glaucomatous optic neuropathy unrelated to previous treatment, and comparable with expected population frequency. These findings, although limited by lack of data from a comparable control population, suggest that eye complications are common in Asian patients with psoriasis and eye symptoms should be elicited during history taking. Besides signs and symptoms of eye disease, an LS-PGA score of more than 5 should prompt referral for ophthalmological examination. [source]

    Short-term resolution of psoriasis after total thyroidectomy for euthyroid multinodular goitre

    AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 3 2002
    Johanna Kuchel
    SUMMARY A 36-year-old Chinese female with an 8-year history of chronic, generalized plaque psoriasis demonstrated a marked improvement of the disease after removal of an intercurrent euthyroid multinodular goitre. Thyroxine was commenced immediately postoperatively. No thyroid antibodies were detected and thyroid function and calcium levels remained within normal limits both pre- and postoperatively. Four weeks following surgery, narrow-band ultraviolet B (nbUVB) therapy was recommenced for recurrent psoriasis. The manifestations of psoriasis at this stage were less severe than before thyroidectomy and responded well to treatment, whereas before surgery the response to therapy had been poor. One year following total thyroidectomy, the patient received very effective psoriasis control with nbUVB therapy. The possible role of surgery and thyroid hormones in altering the pathogenesis of psoriasis in the acute setting is clearly of interest and warrants further research consideration. [source]


    Interleukin-20 plays a critical role in maintenance and development of psoriasis in the human xenograft transplantation model

    BRITISH JOURNAL OF DERMATOLOGY, Issue 2 2009
    K. Stenderup
    Summary Background, Interleukin (IL)-20 is a recently discovered cytokine displaying increased levels in psoriatic lesions. Interestingly, IL-20 levels decrease with antipsoriatic treatment, correlating with clinical improvement. However, the role of IL-20 in the aetiology of psoriasis is unknown. Objectives, In this study, we investigate the effects both of blocking IL-20 signalling in psoriatic plaques and of adding IL-20 to nonlesional psoriasis skin. Methods, We employed the human skin xenograft transplantation model in which psoriatic plaques and nonlesional keratome skin biopsies obtained from donors with moderate to severe plaque psoriasis were transplanted on to immuno-deficient mice. The transplanted mice were treated with anti-IL-20 antibodies or recombinant human IL-20. Results, We demonstrate that blocking IL-20 signalling with anti-IL-20 antibodies induces psoriasis resolution and inhibits psoriasis induction. We also demonstrate that continuous IL-20 infusion, together with injection of additional nonactivated leucocytes, promotes induction of psoriasis in nonlesional skin from patients with psoriasis. Conclusions, The results suggest that IL-20 plays a critical role in the induction and maintenance of psoriasis, and IL-20 is suggested as a new possible specific target in psoriasis treatment.

    Effects of etanercept on C-reactive protein levels in psoriasis and psoriatic arthritis

    BRITISH JOURNAL OF DERMATOLOGY, Issue 2 2008
    B. Strober
    Summary Background, C-reactive protein (CRP), an inflammation biomarker, indicates cardiovascular risk and is elevated in psoriasis. The effect of etanercept on CRP in psoriasis has not been previously examined. Objectives, The primary objective was to examine the effect of etanercept on CRP levels from baseline to week 12 compared with placebo. Secondary objectives included assessment of baseline CRP and relationships between CRP and body mass index (BMI), statin drug use, and Psoriasis Area and Severity Index (PASI) scores. Methods, A retrospective analysis was conducted of CRP levels from patients with psoriasis who participated in a randomized, double-blind, placebo-controlled, U.S. registrational study. Data were analysed separately if patients self-reported psoriatic arthritis. Results, Baseline CRP levels were elevated in patients with psoriasis with and without psoriatic arthritis. CRP was significantly reduced in both groups after 12 weeks of etanercept treatment. Patients with psoriasis with psoriatic arthritis and patients with higher BMIs had higher median baseline CRP values and greater reduction of CRP values compared with those without psoriatic arthritis and those with lower BMIs. Etanercept lowered CRP levels in statin users and nonusers. Regression analyses revealed an association between baseline PASI score and baseline CRP independent of BMI in patients with psoriasis. Conclusions, Patients with moderate to severe plaque psoriasis, with or without psoriatic arthritis, have increased systemic inflammation demonstrated by elevated CRP levels. In psoriasis without psoriatic arthritis, skin disease activity is associated significantly with CRP elevation, independent of BMI, age and sex. Etanercept reduced CRP levels in all but the normal weight psoriasis group without psoriatic arthritis. [source]


    A study examining inter-rater and intrarater reliability of a novel instrument for assessment of psoriasis: the Copenhagen Psoriasis Severity Index

    BRITISH JOURNAL OF DERMATOLOGY, Issue 2 2008
    J. Berth-Jones
    Summary Background, There is a perceived need for a better method for clinical assessment of the severity of psoriasis vulgaris. The most frequently used system is the Psoriasis Area and Severity Index (PASI), which has significant disadvantages, including the requirement for assessment of the percentage of skin affected, an inability to separate milder cases, and a lack of linearity. The Copenhagen Psoriasis Severity Index (CoPSI) is a novel approach which comprises assessment of three signs: erythema, plaque thickness and scaling, each on a four-point scale (0, none; 1, mild; 2, moderate; 3, severe), at each of 10 sites: face, scalp, upper limbs (excluding hands and wrists), hands and wrists, chest and abdomen, back, buttocks and sacral area, genitalia, lower limbs (excluding feet and ankles), feet and ankles. Objectives, To evaluate the inter-rater and intrarater reliability of the CoPSI and to provide comparative data from the PASI and a Physician's Global Assessment (PGA) used in recent clinical trials on psoriasis vulgaris. Methods, On the day before the study, 14 dermatologists (raters) with an interest in psoriasis participated in a detailed training session and discussion (2·5 h) on use of the scales. On the study day, each rater evaluated 16 adults with chronic plaque psoriasis in the morning and again in the afternoon. Raters were randomly assigned to assess subjects using the scales in a specific sequence, either PGA, CoPSI, PASI or PGA, PASI, CoPSI. Each rater used one sequence in the morning and the other in the afternoon. The primary endpoint was the inter-rater and intrarater reliability as determined by intraclass correlation coefficients (ICCs). Results, All three scales demonstrated ,substantial' (a priori defined as ICC > 80%) intrarater reliability. The inter-rater reliability for each of the CoPSI and PASI was also ,substantial' and for the PGA was ,moderate' (ICC 61%). The CoPSI was better at distinguishing between milder cases. Conclusions, The CoPSI and the PASI both provided reproducible psoriasis severity assessments. In terms of both intrarater and inter-rater reliability values, the CoPSI and the PASI are superior to the PGA. The CoPSI may overcome several of the problems associated with the PASI. In particular, the CoPSI avoids the need to estimate a percentage of skin involved, is able to separate milder cases where the PASI lacks sensitivity, and is also more linear and simpler. The CoPSI also incorporates more meaningful weighting of different anatomical areas. [source]


    Impact of adalimumab treatment on health-related quality of life and other patient-reported outcomes: results from a 16-week randomized controlled trial in patients with moderate to severe plaque psoriasis

    BRITISH JOURNAL OF DERMATOLOGY, Issue 3 2008
    D. Revicki
    Summary Background, Health-related quality of life (HRQOL) and other patient-reported outcomes (PROs) are important in evaluating the impact of psoriasis and its treatment. Objectives, To assess the impact of adalimumab treatment on HRQOL and other PROs in patients with moderate to severe psoriasis. Methods, A 16-week, double-blind, double-dummy, randomized controlled trial evaluated the efficacy and safety of adalimumab in 271 adults with moderate to severe chronic plaque psoriasis. Patients were randomized in a 2 : 2 : 1 ratio to adalimumab, methotrexate (MTX) or placebo. PROs were evaluated throughout the study and included the Dermatology Life Quality Index (DLQI), Patient's Global Assessment of disease severity, plaque psoriasis and psoriatic arthritis pain visual analogue scale (VAS), Psoriasis-Related Pruritus Assessment and EuroQOL 5D (EQ-5D). Results, Statistically significant differences were observed between the adalimumab- and placebo-treated and the MTX-treated groups on mean DLQI total scores during the 16-week double-blind study (both P < 0·001). Significant differences, favouring adalimumab compared with placebo, were also observed on the Patient's Global Assessment of disease severity (P < 0·001), VAS for pain (P < 0·001), Psoriasis-Related Pruritus Assessment (P < 0·001), EQ-5D VAS (P < 0·001) and EQ-5D index score (P < 0·01). Compared with MTX, adalimumab resulted in statistically significantly greater improvements in the Patient's Global Assessment of disease severity (P < 0·001), the VAS for pain (P < 0·01) and the Psoriasis-Related Pruritus Assessment (P < 0·001). Conclusions, Adalimumab was efficacious in improving dermatology-specific HRQOL, disease control and symptom outcomes in patients with moderate to severe psoriasis. [source]


    Efficacy and safety results from the randomized controlled comparative study of adalimumab vs. methotrexate vs. placebo in patients with psoriasis (CHAMPION)

    BRITISH JOURNAL OF DERMATOLOGY, Issue 3 2008
    J.-H. Saurat
    Summary Background, Biologic therapies such as adalimumab, a tumour necrosis factor antagonist, are safe and effective in the treatment of moderate to severe chronic plaque psoriasis. Objectives, To compare a biologic agent with methotrexate, a traditional systemic agent, to define clearly the role of biologics in psoriasis. Methods, Patients with moderate to severe plaque psoriasis were randomized to adalimumab (80 mg subcutaneously at week 0, then 40 mg every other week, n = 108), methotrexate (7·5 mg orally, increased as needed and as tolerated to 25 mg weekly; n = 110) or placebo (n = 53) for 16 weeks. The primary efficacy endpoint was the proportion of patients achieving at least a 75% improvement in the Psoriasis Area and Severity Index (PASI 75) after 16 weeks. Safety was assessed at all visits through week 16. Results, After 16 weeks, 79·6% of adalimumab-treated patients achieved PASI 75, compared with 35·5% for methotrexate (P < 0·001 vs. adalimumab) and 18·9% for placebo (P < 0·001 vs. adalimumab). Statistically significantly more adalimumab-treated patients (16·7%) than methotrexate-treated patients (7·3%) or placebo-treated patients (1·9%) achieved complete clearance of disease. The response to adalimumab was rapid, with a 57% improvement in mean PASI observed at week 4. Adverse events were similar across treatment groups. Adverse events leading to study discontinuation were greatest in the methotrexate group, primarily because of hepatic-related adverse events. Conclusions, After 16 weeks, adalimumab demonstrated significantly superior efficacy and more rapid improvements in psoriasis compared with either methotrexate or placebo. [source]


    Oral retinoic acid metabolism blocking agent RambazoleTM for plaque psoriasis: an immunohistochemical study

    BRITISH JOURNAL OF DERMATOLOGY, Issue 2 2007
    H.J. Bovenschen
    Summary Background, The novel systemic all- trans retinoic acid metabolism blocking agent (RAMBA) R115866 (RambazoleTM; Barrier Therapeutics, Geel, Belgium; further referred to as rambazole) increases intracellular levels of endogenous all- trans retinoic acid (RA). Well-known effects of RA are normalization of aberrant epithelial growth and differentiation. Hence, rambazole might be beneficial in the treatment of plaque psoriasis. Objectives, The dynamics of epidermal proliferation, keratinization, lesional T-cell subsets and cells expressing natural killer (NK)-receptors in plaque psoriasis were assessed during treatment with rambazole, as part of a phase IIa open-label clinical trial. Methods, Six patients were treated with rambazole, 1 mg, once daily, for 8 weeks. At weeks 0, 2 and 8, psoriatic plaque severity scores (SUM) and biopsies from a target lesion were assessed. Epidermal proliferation (Ki67), keratinization markers (K10, K13, K19), T-cell subsets (CD3, CD4+, CD8+, CD45RO+, CD45RA+, CD2+, CD25+, GITR+) and cells expressing NK-receptors (CD94, CD161) were immunohistochemically stained and quantified with image analysis. Results, At week 2 the mean SUM-score was virtually equal to baseline, which was accompanied immunohistochemically by equal epidermal hyperproliferation, a nonsignificant decrease in K10 positive epidermis and, overall, a nonsignificant increase in immunocyte subsets. At week 8, in contrast, plaque severity was reduced by 34% from baseline (P < 0·05). Improvements were also detected for epidermal proliferation (,63%; P < 0·01) and K10 expression (+29%; P < 0·01), compared with baseline. No induction of retinoid-specific keratinization (K13, K19) was observed. A nonsignificant reduction of all pathogenic T-cell subsets and cells expressing NK-receptors was observed at week 8 of treatment (P > 0·05). Conclusions, Clinical efficacy of rambazole is primarily the result of restoring proliferation (Ki67) and differentiation (K10) of epidermal keratinocytes. Secondly, relevant T-cell subsets and cells expressing NK-receptors showed nonsignificant reductions after 8 weeks of treatment with rambazole. [source]


    Plasma homocysteine and folate levels in patients with chronic plaque psoriasis

    BRITISH JOURNAL OF DERMATOLOGY, Issue 6 2006
    M. Malerba
    Summary Background, Hyperhomocysteinaemia is a well-known risk factor for cardiovascular diseases. Patients with severe chronic plaque psoriasis have a higher risk of death due to arterial and/or venous thrombosis. Objectives, To investigate the relationship among plasma homocysteine and folate levels and severity of chronic plaque psoriasis in a selected cohort of patients with psoriasis without known risk factors for acquired hyperhomocysteinaemia. Methods, We performed a case,control study in 40 patients with chronic plaque psoriasis and 30 age- and sex-matched healthy controls. Cases and controls were selected excluding individuals with conditions or diseases associated with acquired hyperhomocysteinaemia, and were also asked to stop alcohol and coffee consumption for 1 week before blood sampling. The plasma levels of homocysteine and folic acid were measured and were correlated with the severity of psoriasis (Psoriasis Area and Severity Index, PASI). Results, Patients with psoriasis had plasma homocysteine levels higher than controls (mean ± SD 16·0 ± 5·6 vs. 10·4 ± 4·7 ,mol L,1; P < 0·001). Conversely, folic acid levels were lower in patients with psoriasis compared with controls (mean ± SD 3·6 ± 1·7 vs. 6·5 ± 1·7 nmol L,1; P < 0·001). Plasma homocysteine levels in patients with psoriasis correlated directly with disease severity (PASI) and inversely with folic acid levels. Plasma folic acid levels were inversely correlated with the PASI. No abnormalities of plasma vitamin B6 and B12 were found. Conclusions, Patients with psoriasis may have a tendency to hyperhomocysteinaemia, which may predispose to higher cardiovascular risk. Dietary modification of this risk factor appears relevant to the global management of patients with moderate to severe psoriasis. [source]


    A study examining inter- and intrarater reliability of three scales for measuring severity of psoriasis: Psoriasis Area and Severity Index, Physician's Global Assessment and Lattice System Physician's Global Assessment

    BRITISH JOURNAL OF DERMATOLOGY, Issue 4 2006
    J. Berth-Jones
    Summary Background, There is a lack of consensus as to the best way of monitoring psoriasis severity in clinical trials. The Psoriasis Area and Severity Index (PASI) is the most frequently used system and the Physician's Global Assessment (PGA) is also often used. However, both instruments have some drawbacks and neither has been fully evaluated in terms of ,validity' and ,reliability' as a psoriasis rating scale. The Lattice System Physician's Global Assessment (LS-PGA) scale has recently been developed to address some disadvantages of the PASI and PGA. Objectives, To evaluate the inter-rater and intrarater reliability of the PASI, PGA and LS-PGA. Methods, On the day before the study, 14 dermatologists (raters), with varied experience of assessing psoriasis, received detailed training (2·5 h) on use of the scales. On the study day, each rater evaluated 16 adults with chronic plaque psoriasis in the morning and again in the afternoon. Raters were randomly assigned to assess subjects using the scales in a specific sequence, either PGA, LS-PGA, PASI or PGA, PASI, LS-PGA. Each rater used one sequence in the morning and the other in the afternoon. The primary endpoint was the inter-rater and intrarater reliability as determined by intraclass correlation coefficients (ICCs). Results, All three scales demonstrated ,substantial' (a priori defined as ICC > 80%) intrarater reliability. The inter-rater reliability for each of the PASI and LS-PGA was also ,substantial' and for the PGA was ,moderate' (ICC 75%). Conclusions, Each one of the three scales provided reproducible psoriasis severity assessments. In terms of both intrarater and inter-rater reliability values, the three scales can be ranked from highest to lowest as follows: PASI, LS-PGA and PGA. [source]
