Summary: This review provides a summary of key findings from 27 systematic reviews of 51 articles first published or indexed during 2015, focusing on the treatment of psoriasis and on precision medicine in psoriasis. The evidence supports weight‐loss interventions by dieting and exercise for improvement in disease severity in overweight and obese patients with psoriasis. No significant increased risk of serious infections was reported for the biologic therapies adalimumab, etanercept and ustekinumab compared with appropriate comparators. Evidence could not provide reliable estimates of rare adverse events, emphasizing the need for large prospective registries. Polymorphisms in the tumour necrosis factor (TNF)‐α gene may confer improved responses to TNF inhibitor (TNFI) therapy, but the studies to date lack power to detect a true association. From the limited available evidence, multidisciplinary management is both more effective and more satisfactory for patients with psoriasis and psoriatic arthritis than conventional consultations. This summary of reviews provides a succinct guide for clinicians and patients wishing to remain up to date with high‐quality evidence for the treatment of psoriasis. [ABSTRACT FROM AUTHOR]

An evaluation of dermatology patients shielding during the COVID-19 outbreak Retrospective analysis of patient records/pharmacy lists revealed 1071 patients that met the British Association of Dermatologists' criteria for shielding.4 Printed letters were posted to these patients, advising them accordingly. In conclusion, the majority of our highly vulnerable dermatology patients shielded, continued to take their immunosuppressive medication and denied any symptoms of COVID-19.

Summary [ABSTRACT FROM AUTHOR]

This review summarizes the clinical importance of 18 systematic reviews and guidelines on psoriasis published or indexed between November 2008 and October 2009. The topics covered include guidance on the use of topical, systemic and biological therapies for the treatment of psoriasis; comorbidities associated with psoriasis; and complementary therapies for psoriasis. A similar and more detailed review to this appeared in the 2009 Annual Evidence Update on Psoriasis from NHS Evidence – Skin Disorders in November 2009. [ABSTRACT FROM AUTHOR]

This review summarizes the clinical importance of six systematic reviews on psoriasis published between January 2007 and October 2008. A meta-analysis demonstrated that several traditional nonbiological systemic therapies have equal or superior efficacy to some biological therapies used in the treatment of psoriasis. Two further meta-analyses comparing biological therapies for psoriasis (excluding adalimumab) have established a hierarchy of efficacy for short-term treatment (10–16 weeks): infliximab > etanercept 50 mg twice weekly > etanercept 25 mg twice weekly > efalizumab > alefacept. Excluding adalimumab, rates of adverse events are significantly higher for biological therapies than for placebo, except for etanercept at both 25 and 50 mg twice weekly. Further, head to head trials of biological therapies for psoriasis and longer-term safety data on their use are required. Psoriasis can be induced by and/or exacerbated during antitumour necrosis factor (TNF) therapy. It is recommended to initially switch anti-TNF agent in this situation and only discontinue therapy if psoriasis is extensive and/or intolerable, allowing the primary disease to remain under control. Most screening and monitoring tests carried out during treatment of psoriasis with biological therapies are neither supported nor refuted by current evidence and the clinician must assess each case individually. Studies designed specifically to assess appropriate use of these tests are required. Further research is needed to evaluate the effectiveness of existing psychological interventions in psoriasis. The effectiveness of support groups has not been adequately proven, although there are limited data supporting the use of cognitive behavioural therapy. [ABSTRACT FROM AUTHOR]

Methotrexate’s traditional role as a first line agent for moderate to severe psoriasis is being challenged by the rapid and growing use of biological therapies. A recent study comparing adalimumab with methotrexate showed significantly superior efficacy of adalimumab over methotrexate over 16 weeks. Although it is inexpensive, the future use of methotrexate may be compromised by its unpredictable response and toxicity, and by the introduction of newer, more effective biological therapies. However, recent advances in the screening of liver fibrosis by monitoring serum levels of the aminoterminal peptide fragment of type III procollagen have reduced the need for liver biopsy. Furthermore, the potential for personalized methotrexate use by application of modern pharmacogenetics and pharmacokinetics may ensure its place as a first-line agent for the treatment of psoriasis for the foreseeable future.

A letter to the editor is presented which discusses the effectiveness of combining infliximab and methotrexat to obtain a long-term control of recalcitrant psoriasis.
