Meta Analysis
Genome-wide association study meta-analysis of chronic widespread pain: evidence for involvement of the 5p15.2 region.
Chronic widespread pain (CWP) is a common disorder affecting ∼10% of the general population and has an estimated heritability of 48-52%. In the first large-scale genome-wide association study (GWAS) meta-analysis, we aimed to identify common genetic variants associated with CWP. ⋯ We identified a common genetic variant on chromosome 5p15.2 associated with joint-specific CWP in humans. This work suggests that CCT5 and FAM173B are promising targets in the regulation of pain.

The Xq28 region containing IRAK1 and MECP2 has been identified as a risk locus for systemic lupus erythematosus (SLE) in previous genetic association studies. However, due to the strong linkage disequilibrium between IRAK1 and MECP2, it remains unclear which gene is affected by the underlying causal variant(s) conferring risk of SLE. ⋯ These data suggest contributions of both IRAK1 and MECP2 to SLE susceptibility.

A high percentage of patients with systemic sclerosis (SSc) develop interstitial lung disease (ILD) during the course of the disease. Promising data have recently shown that lung ultrasound (LUS) is able to detect ILD by the evaluation of B-lines (previously called ultrasound lung comets), the sonographic marker of pulmonary interstitial syndrome. ⋯ ILD may be detected in patients with very early SSc. The presence of B-lines at LUS examination correlates with ILD at HRCT. LUS is very sensitive for detecting ILD even in patients with a diagnosis of very early SSc. The use of LUS as a screening tool for ILD may be feasible to guide further investigation with HRCT.

Randomized Controlled Trial Multicenter Study
Efficacy and safety of strontium ranelate in the treatment of knee osteoarthritis: results of a double-blind, randomised placebo-controlled trial.
Strontium ranelate is currently used for osteoporosis. The international, double-blind, randomised, placebo-controlled Strontium ranelate Efficacy in Knee OsteoarthrItis triAl evaluated its effect on radiological progression of knee osteoarthritis. ⋯ Treatment with strontium ranelate 1 and 2 g/day is associated with a significant effect on structure in patients with knee osteoarthritis, and a beneficial effect on symptoms for strontium ranelate 2 g/day.

Randomized Controlled Trial Multicenter Study
Clinical, functional and radiographic consequences of achieving stable low disease activity and remission with adalimumab plus methotrexate or methotrexate alone in early rheumatoid arthritis: 26-week results from the randomised, controlled OPTIMA study.
To assess the efficacy and safety of adalimumab plus methotrexate (ADA+MTX) compared with methotrexate monotherapy in achieving stable low disease activity (LDA; disease activity score (DAS28(CRP)) <3.2 at weeks 22 and 26) and clinical, radiographic and functional outcomes in methotrexate-naive patients with early rheumatoid arthritis (RA). ⋯ Treatment with ADA+MTX was significantly superior to methotrexate alone with respect to clinical, radiographic and functional outcomes in patients with early active RA. Before initiating treatment with adalimumab, individual patient evaluation of the benefit/risk ratio should be carefully considered.
