High paraoxonase activity is associated with a significantly reduced risk of MACE and non-NMSC malignancies in white/European RA patients. The PON1 Q192R RR genotype had a significantly greater association with paraoxonase versus the QQ genotype, but had no significant association with MACE or non-NMSC malignancies.

This systematic review identified DMARDs evaluated for axSpA and PsA, distinguishing between csDMARDs, tsDMARDs, and bDMARDs. The review pinpointed twenty-six distinct targeted therapies currently in clinical development; 18 therapies for axSpA and 15 therapies for PsA.

This study concluded that, in r-axSpA, vertebral corner inflammation may lead to syndesmophyte formation but in a minority of cases via visible fat deposition. Here, investigators aimed to determine how much of the effect of vertebral corner inflammation on the development of syndesmophytes is explained by vertebral corner fat deposition.

This review by Taylor, et al. reviews the long-term safety and efficacy data for baricitinib. Results from several studies showed that baricitinib has greater efficacy and survival compared to TNF inhibitors, and that the rate of CDAI <10 for baricitinib-treated RA patients increased over the course of seven years. Data also showed that remission rates were higher in real-world evidence than in RCTs.

Phase 3 trial of baricitinib demonstrates efficacy with acceptable safety profile in polyarticular and extended oligoarticular juvenile idiopathic arthritis, juvenile psoriatic arthritis and enthesitis-related arthritis.

Data from this open-label extension showed the efficacy of upadacitinib observed at 56 weeks was maintained through to 152 weeks in the treatment of patients with PsA. No cumulative adverse effects were observed, and no new safety signals were identified.

Cicirello, et al. present results showing that baricitinib is comparable in treatment persistence with TNF inhibitors. However, treatment persistence up to 24 months was significantly longer for baricitinib, but the effect size of one month is not clinically meaningful.

Mirikizumab as induction and maintenance therapy for ulcerative colitis

N Engl J Med 2023;388(26):2444–2455 doi: 10.1056/NEJMoa2207940

Mirikizumab was more effective than placebo in inducing and maintaining clinical remission in patients with moderately to severely active ulcerative colitis. D’Haens, et al. also noted that opportunistic infections and cancer developed in a small number of mirikizumab-treated patients.

This single-centre study by Khan, et al. suggests that high-dose methotrexate (25 mg/week, subcutaneously) may be as efficacious as tofacitinib in patients with established RA who are DMARD naïve or have not received a therapeutic dose of DMARDs.

This real-world study showed that sustained BASDAI <3 may be a valid and feasible target for a treat-to-target strategy in AxSpA, having function as treatment goal.
