Year in Review in 2017

Inhibitors of β-nerve growth factor (NGF) have impressive effects in reducing musculoskeletal pain, but have also been associated with adverse events of unclear aetiology. Several studies in the past year have sought to clarify the relative benefits and risks of anti-NGF treatment.

In 2016, there have been several major scientific achievements related to myositis, including the discovery of a novel autoantibody and the relationship between autoantibodies and distinct clinical phenotypes. Advances in the way clinical trials are conducted have also led to breakthroughs in treatment strategies.

Several strands of new research indicate that skin-specific adipocyte progenitor cells regulate myofibroblasts and skin fibrosis in scleroderma.

Rheumatoid arthritis is associated with an expansion of certain gut commensals, although the underlying mechanism remains unknown. In 2016, studies using experimental models of arthritis have begun to unravel the links between the gut microbiota, T follicular helper cells and arthritis.

Gene expression profiling has been used for the first time to stratify patients with systemic lupus erythematosus (SLE) into potentially useful clinical groups, and also to further understand differences in the cell-specificity and nature of the interferon signature typical of SLE and other autoimmune diseases.

Regenerative medicine can be viewed as 'tissue engineering V2.0'. Discoveries and novel applications of technology advanced the field considerably in 2016, with the use of new biomaterials, stem cells and biologically active molecules.
