Circulating CD19+CD24hiCD38hi regulatory B cells as biomarkers of response to methotrexate in early rheumatoid arthritis.

Objective: The protagonism of regulatory B cells seems to vary along the course of the disease in murine models of inflammatory conditions. Decreased numbers of circulating regulatory CD19+CD24hiCD38hi transitional (cTr) B cells have been described in patients with long-standing RA, thus our objective was to examine the frequency and evolution of cTr B cells in the peripheral blood of early RA (ERA) patients.

Methods: Freshly isolated peripheral blood mononuclear cells from 48 steroid- and DMARD-naïve ERA patients with a disease duration of <24 weeks and 48 healthy controls (HCs) were examined by flow cytometry.

Reducing or Maintaining the Dose of Subcutaneous Tocilizumab in Patients With Rheumatoid Arthritis in Clinical Remission: A Randomized, Open-Label Trial.

Objective: To evaluate the efficacy and safety of increasing the dose interval of subcutaneous tocilizumab (TCZ-SC) in patients with rheumatoid arthritis (RA) who are in clinical remission.

Methods: RA patients with active disease and an inadequate response to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) or to a biologic agent were entered into a single-arm treatment phase with 162 mg of TCZ-SC administered once weekly (TCZ-SC 162 mg qw) as monotherapy or in combination with a csDMARD for 24 weeks. Patients who achieved clinical remission at weeks 20 and 24 were randomized to continue with the same regimen or to switch to 162 mg TCZ-SC administered every 2 weeks (TCZ-SC 162 mg q2w) for 24 weeks (open-label).

Efficacy of tocilizumab monotherapy after response to combined tocilizumab and methotrexate in patients with rheumatoid arthritis: the randomised JUST-ACT study.

Objectives: The aim of the JUST-ACT study was to assess whether the add-on effect of tocilizumab (TCZ) to background methotrexate (MTX) observed in MTX-inadequate responders with active rheumatoid arthritis (RA), would be sustained when MTX is withdrawn.

Methods: A double-blind, parallel-group, phase 3 study in biologic-naïve RA patients with a disease activity score 28 (DAS28)>3.2 despite MTX which were treated with TCZ+MTX for an initial 16-week period.

Induction of sustained remission in early inflammatory arthritis with the combination of infliximab plus methotrexate: the DINORA trial.

Background: In the present study, we explored the effects of immediate induction therapy with the anti-tumour necrosis factor (TNF)α antibody infliximab (IFX) plus methotrexate (MTX) compared with MTX alone and with placebo (PL) in patients with very early inflammatory arthritis.

Methods: In an investigator-initiated, double-blind, randomised, placebo-controlled, multi-centre trial (ISRCTN21272423, http://www.isrctn.
