Inception SLE study of 674 pts (without LN), mean age 34 yrs - 154 (23%) developed new proteinuria (LN) after median of 3.6 yr. Cumulative antimalarial exposure did NOT lower risk of LN (HR 0.98; 0.94-1.02); same for those w/ serologically active SLE (HR 0.97) https://t.co/8OU3yJAvhN

Italian Systemic sclerosis (SPRING-SIR) registry - 1157/1538 (75%) SSc pts were in menopause, 632 (50%) had pre-menop SSc onset, 130 (14.4%) had early menopause. Post-menop. had more CREST, centromere Abs, ILD & GI Sxs. Pre-menop. had more diffuse Dz & peripheral vasculopathy. https://t.co/Jz2v5CkH0Y

MUC5 mutations not in SSc-ILD. Study of 2363 SSc-ILD, 3526 SSc w/o ILD & 15076 controls. They found no assoc w/ MUC5B promoter variant & SSc-ILD. (Suggesting ILD pathogenic mechanisms differ between RA and SSc) https://t.co/bBq52X0Mwq https://t.co/eu1IpaXGL8
