Autoantibodies (AAbs) against interleukin-21 correlate with disease activity in patients with rheumatoid arthritis (RA). The levels of AAbs against IL-21 correlate with disease activity, which suggests that anti–IL-21 AAbs may play a role in the pathogenesis of RA. PubMed, Clin Rheumatol, 10/10/2017.

Serum serotonin levels and bone in rheumatoid arthritis (RA) patients. Our data reinforce a role, despite weak, for circulating serotonin in regulating bone mass in RA patients, with some differences in terms of gender and anatomical sites.

Incidence and predictors of osteoporotic fractures in patients with Barrett's oesophagus (BO): a population–based nested case–control study. The incidence of osteoporotic fractures was not increased in BO patients compared to the general population and proton pump inhibitors use was not associated with increased fracture risk.

Metabolic and cardiovascular benefits of hydroxychloroquine (HCQ) in patients with rheumatoid arthritis (RA) : a systematic review and meta–analysis. HCQ may benefit the metabolic profile and to a lesser extent cardiovascular events in patients with RA, which suggests its usefulness combined with other conventional synthetic disease–modifying antirheumatic drugs.

Bidirectional association between fibromyalgia (FM) and gastroesophageal reflux disease (GERD): two population–based retrospective cohort analysis. The present study suggests a bidirectional relationship between FM and GERD and there is a greater risk of developing GERD for patients with FM than developing FM for patients with GERD.

Targeted proteomics reveals promising biomarkers of disease activity and organ involvement in antineutrophil cytoplasmic antibody–associated vasculitis (AAV). Promising biomarkers of disease activity, disease severity, and organ involvement in AAV with a targeted proteomics approach using serum samples have been obtained.

Residual disease activity and treatment adjustments in psoriatic arthritis (PsA) in current clinical practice. Remaining disease activity is present in almost two thirds of patients with PsA when scored by the treating rheumatologist, but triggers treatment adjustment in only a minority.

Activating and inhibitory receptors on natural killer cells in patients with systemic lupus erythematosis (SLE)–regulation with interleukin-15. Natural killer (NK) cells may play an important role in the pathogenesis of SLE. PubMed, PLoS One, 2017 Oct 12;12(10):e0186223. (Also see Causes of Lupus and Natural Killer Cells)
Association between anti–citrullinated fibrinogen antibodies and coronary artery disease (CAD) in rheumatoid arthritis (RA). Anti–cit–fibrinogen antibodies as a group were associated with CAD outcomes in our RA cohort, with the strongest signal for association arising from a subset of the autoantibodies. PubMed, Arthritis Care Res (Hoboken), 10/08/2017. (Also see Diagnosis of Rheumatoid Arthritis)
Association of interleukin 13 gene polymorphisms and plasma IL 13 level with risk of systemic lupus erythematosus (SLE). The concentration of IL-13 was significantly elevated in rs20541 CT/TT genotypes compared with CC genotype which suggests that rs20541 CT/TT genotypes may be a risk factor for SLE. PubMed, Cytokine, 10/07/2017. (Also see Causes of Lupus and Interleukins)
