Lung involvement is a well-recognized extra-articular manifestation of ankylosing spondylitis (AS). Anecdotal reports suggest that the use of anti-TNF drugs may be related to lung disease and pulmonary fibrosis. To examine the association between anti-TNF drugs and the development of lung disease in patients with AS or psoriatic arthritis (PsA) we conducted a systematic review. Of the 670 papers identified by means of key word and hand search, only one full-text paper was considered potentially relevant but had to be discarded as it did not meet the eligibility criteria. Although no conclusion was reached, this is the first systematic review to examine this problem which is becoming increasingly important as these drugs are widely prescribed in patients with spondyloarthritis.

Chikungunya fever (CHIK-F) has been increasingly documented among Western travelers returning from areas with chikungunya virus transmission, which are also popular tourist sites. We present three Israeli travelers who developed fever, maculopapular rash and long-standing arthralgias while visiting northern Indian states not known to be involved in the chikungunya fever epidemic. We also present an epidemiological review of the chikungunya epidemic over the past decades. Rare systemic manifestations of this disorder, like catastrophic antiphospholipid syndrome (CAPS) and adult onset still’s syndrome, are discussed. The present era of international travel poses a novel diagnostic and epidemiologic challenge and we must increase our awareness to the possibility of an exotic tropical infectious disease.

Psoriatic arthritis (PsA) is a chronic inflammatory condition associated with skin psoriasis and manifests a wide clinical phenotype, with proposed differences between sexes. Current treatments are based on traditional disease-modifying anti-rheumatic drugs (DMARD), and biologic agents and studies have reported different clinical response patterns depending on sex factors. We aimed to identify sex differences in drug retention rate in patients with PsA and performed a systematic research on MEDLINE, EMBASE and Cochrane databases (1979 to June 2015) for studies regarding effectiveness (measured as drug retention rate) in PsA in both traditional DMARDs and biologics. Demographic data as well as retention rates between sexes were extracted. From a total 709 retrieved references, we included 9 articles for the final analysis. Only one study reported data regarding DMARDs, while eight studies reported retention rate for anti-tumor necrosis factor (TNF) biologics, mainly infliximab, adalimumab and etanercept. No differences were reported in retention rates between sexes for methotrexate, while women manifested lower retention rates compared to men with regard to anti-TNF. We highlight the need to include sex differences in the management flow chart of patients with PsA.

Background: Balneotherapy is one of the most commonly used non-pharmacological approaches for osteoarthritis (OA). Recent data indicate that some biomarkers could be useful to predict OA progression and to assess therapeutic response.
Objectives: To evaluate the effects of mud-bath therapy on serum biomarkers in patients with knee OA.
Methods: The study group comprised 103 patients with primary symptomatic bilateral knee OA who were randomly assigned to receive a cycle of mud-bath therapy over a period of 2 weeks or to continue their standard therapy alone. Clinical and biochemical parameters were assessed at baseline and after 2 weeks. Clinical assessments included global pain score on a Visual Analogue Scale (VAS) and the Western Ontario and McMaster Universities Index (WOMAC) subscores for knee OA. Cartilage oligomeric matrix protein (COMP), C-terminal cross-linked telopeptide type II collagen (CTX-II), myeloperoxidase (MPO) and high sensitivity C-reactive protein (hsCRP) serum levels were assessed by ELISA.
Results: At the end of mud-bath therapy we observed a statistically significant improvement in VAS and WOMAC subscores. Serum levels of COMP, MPO and hsCRP did not show any significant modification in both groups, while a significant increase (P < 0.001) in CTX-II serum levels was observed in the mud-bath group after the treatment.
Conclusions: A cycle of mud-bath therapy added to usual treatment had a beneficial effect on pain and function in patients with knee OA. The evaluation of serum biomarkers showed only a significant increase of CTX-II, perhaps due to an increase of cartilage turnover induced by thermal stress.
