Show Notes:

- TB Infection or reactivation is Psoriasis or Psoriatic Arthritis pts taking IL-23 inhibitors is rare, rare. Literature review showed 34 studies of IL-23i in PsO had no new TB, but 1 case of LTBI reactivation. In 8 IL-23i PsA studies there were NO new TB or LTBI reactivations https://t.co/NFIap7DSOr  

- BE BOLD: Bimekizumab Beats Risankizumab (LB0001) –H2H trial bimekizumab vs risankizumab in PsA for 24 weeks. At week 16; BKZ better than RZB,  p=0.0058). This advantage was maintained out to week 24 (55% vs 44%; p 0.0001).

- RA-BRIDGE and RA-BRANCH: FDA mandated study of the risk of venous thromboembolic events (VTE) taking baricitinib (BARI) or TNF inhibitors. The incidence rate was 0.79/100 PY for BARI combined versus 0.51/100 PY for TNFi. The hazard ratio was 1.606 (95% CI 0.969–2.660), with the upper CI exceeding the pre-specified NI margin of 1.8.  Baricitinib (neither dose) was associated with a higher risk of MACE (HR 1.06), all-cause mortality (HR 0.97), arterial thromboembolism (HR 1.27), or opportunistic infections (HR 1.25).  

- Probiotics in Psoriatic Arthritis. (POS0290)    66 PsA patients randomized to receive either placebo or probiotic containing lactobacillus and bifidobacterium strains for 12 weeks.  This trial proves no significant effect with oral probiotic supplementation in PsA. 

- CLE and smoking. Smoking reduces efficacy of antimalarials & worsens dz activity & damage. Advocate for smoking cessation! @Rheumnow #EULAR2026 https://t.co/pEWLJAkBAJ

- Risk of Psoriasis is increased 19% by long-term exposure to Particulate Matter (PM2.5 & PM10; adjHR 1.19), while short-term exposure increases risk of psoriasis exacerbation (adjusted OR 1.03). Stronger in younger, urban, lower SES, ever-smokers, & comorbid allergies https://t.co/pd6S13RG1B
