To evaluate the effects of therapeutic exercise on pain, stiffness, quality of life, physical function, disease activity, health-related fitness and cardiovascular risk factors in adults with spondyloarthritis (SpA). Electronic databases (Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE/PubMed, PEDro, AMED, CINAHL) were systematically searched from inception to October 2013 using medical subject headings and keywords. This was supplemented by searching conference abstracts and a hand search of reference lists of included studies. ⋯ The addition of aerobic components to flexibility programmes improves cardiorespiratory outcomes, but not cardiovascular risk factors. The most effective exercise protocol remains unclear. Current evidence suggests that therapeutic exercises are beneficial for adults with ankylosing spondylitis; effects on other SpA subtypes are unknown.

Fibromyalgia (FM) is recognized as a common condition, characterized by widespread pain and associated with sleep disturbances and poor-quality sleep. The Pittsburgh Sleep Questionnaire Index (PSQI) is one of the most recommended instruments to measure sleep quality and sleep disorders. The purpose of our study was to translate the questionnaire into Spanish and to assess the psychometric properties of the Spanish version of the PSQI. ⋯ A two-factor structure was generated by exploratory factor analysis, with a Cronbach's alpha of 0.866 for factor 1 and of 0.712 for factor 2. In convergent validity analysis, the PSQI total score showed a significant correlation (p < 0.01) with the FIQ total score and with the mental and physical health summaries scores of the SF-36. Our results show that the Spanish version of the PSQI provides a reliable instrument, with a good convergent validity for measuring sleep quality among Spanish FM patients.

Ultrasound evaluation of greater trochanter pain syndrome in patients with spondyloarthritis: are there any specific features?
Although greater trochanter pain syndrome (GTPS) is a prevalent cause of musculoskeletal pain in the general population, there is lack of imaging studies searching for differential features of inflammatory enthesitis in GTPS. We analyzed the features of GTPS using sonography and magnetic resonance imaging (MRI) to identify useful differential signs between spondyloarthritis (SpA) and other inflammatory or non-inflammatory musculoskeletal diseases. All patients with unilateral GTPS attended by our Arthritis Unit between February 2011 and March 2012 were included. ⋯ MRI confirmed the changes detected by ultrasound in all 40 patients evaluated. GTPS in patients with SpA has similar sonographic findings to those observed in patients with RA and patients without musculoskeletal inflammatory disease. Neither sonography nor MRI was clinically useful in classifying GTPS as a manifestation of SpA.

Hip and knee osteoarthritis (OA) is a common cause of disability, with great quality of life and economic impact, hence the need for effective treatment. Patient satisfaction with treatment is a measure of therapeutic effectiveness and may be used to assess treatment switch in OA patients. A 3-month multicenter, prospective, epidemiologic, non-interventional study was conducted in patients with hip and/or knee OA to assess therapeutic efficacy in patients requiring treatment switch due to lack of effectiveness and/or tolerability in primary care settings. ⋯ At 3 months, the standardized (0-100) overall ARTS score increased from 57.7 to 71.6 (p < 0.0001), while disease severity decreased. There was a significant (p < 0.0001) negative association between the ARTS, and the WOMAC and VAS scores. Treatment switching from acetaminophen to NSAIDs as a consequence of poor effectiveness and/or tolerability resulted in increased patient satisfaction with treatment and lower OA severity.

We aimed, first, to investigate the minor allele frequencies (MAFs) of single nucleotide polymorphisms (SNPs) associated with serum uric acid (SUA) level in the Korean population and compare these with data from other ethnic groups and, second, to investigate whether the SNPs are associated with altered SUA levels. We examined the frequencies of risk alleles, investigated the MAFs of 40 previously described SNPs associated with SUA level in the Korean population (a total of 1,957 subjects), and compared results with data for other ethnic groups. We also analyzed associations with SUA concentrations based on data from genome-wide association studies in the Korean population (a total of 402 rheumatoid arthritis subjects) and tested whether polymorphism of any of the 40 SNPs associated with SUA identified previously was associated with SUA levels. ⋯ We also analyzed 13 SNPs shown previously by meta-analysis to be associated with SUA, and SNP rs3741414 (INHBC) was found to have probable association with SUA level observed in the present study (P_trend = 0.01). The pattern of variants controlling SUA levels in the Korean population is not similar to that in European population. SNP rs12734001 (PPP1R12B) is significantly associated with SUA level among Koreans.
