Identification of gene expression biomarkers to predict clinical response to methotrexate in patients with rheumatoid arthritis.

Objectives: To identify biomarkers at the gene expression level to predict response to methotrexate (MTX) in patients with rheumatoid arthritis (RA).

Methods: MTX-naïve patients with RA were started on MTX and followed up over three months. The disease activity score 28 (DAS28) was used to classify patients into responders and non-responders.

The impact of C-reactive protein levels on the effectiveness of upadacitinib in patients with rheumatoid arthritis: a 12-month prospective, non-interventional German study.

Objectives: We investigated whether the effectiveness of upadacitinib in rheumatoid arthritis (RA) treatment is affected by baseline CRP levels in a real-world setting.

Methods: UPwArds was a prospective, non-interventional study. Patients had moderate-to-severe RA and an inadequate response or intolerance to ≥1 disease-modifying anti-rheumatic drug (DMARD).

Posttraumatic stress disorder in fibromyalgia syndrome: prevalence, temporal relationship between posttraumatic stress and fibromyalgia symptoms, and impact on clinical outcome.

A link between fibromyalgia syndrome (FMS) and posttraumatic stress disorder (PTSD) has been suggested because both conditions share some similar symptoms. The temporal relationships between traumatic experiences and the onset of PTSD and FMS symptoms have not been studied until now. All consecutive FMS patients in 8 study centres of different specialties were assessed from February 1 to July 31, 2012.
