Misuse of laboratory testing may lead to misdiagnoses and mismanagement; this is particulary prevalent when clinicians consider the use of the diagnostic use of serological autoimmune markers.
Article
A Lancet Rheumatology systematic review shows the prevalence of hyperuricaemia has risen markedly over the past two decades in both men and women, owing to population growth, aging, and increasing age-specific rates

Prospective multinational cohort of 1180 lupus pts, followed ~2.7 yrs. 37% had renal biopsies (Class III/IV 56%). They achieved mCRR 46%, mPERR 53%, LLDAS 60%, & REMission 46% at least once. renal response highest @ 2 yrs. New organ damage 11% @ 1yr; 33% by 5yr. https://t.co/ugh60M08Xf

Urinary biomarkers improve w/ anifrolumab in TULIP-LN (lupus nephritis) trial; 112 pts, 197 uriniary proteins assessed. Urinary CD163 and MCP-1 signif improved as early as wk 12. Anifrolumab reduced the proteomic inflammatory signature, regardless of responder status https://t.co/n6fIJVDCN1

Cross-sectional study of 180 PMR pts compared dz activity by PMR-AS to Systemic Immune-Inflammation Index (SII = Plts × PMNs/Lymphs) using CBC.48% had mod-hi dz (PMR-AS >=7). SII had moderate correlation with PMR-AS (r = 0.47), possibly useful in monitoring PMR https://t.co/vG1alSdVRU

Metanalysis of calcineurin inhib. in RA - 11 RCTs, 1793 RA pts. Cyclosporin (CSA( (RR 1.6 & Tacrolimus (TAC (RR 2.1) signif improved ACR20 responses. CSA was dose dependent, less so w/ TAC. Both require serum Creat. monitoring consistent increase in s-Cr https://t.co/OxNGYbupnt https://t.co/F08vDCMYtr

US Epidemiologic survey data from NHANES gout prevalence is incr. in RA pts vs controls (10.3% vs. 4.8%, P < 0.001), increasing trend over time. RA is as an independent risk factor for gout (OR: 2.67), strongest in SNRA. Evidence for the converse may not be as strong. https://t.co/hhRT9NCzVG

Metanalysis of 8 articles, 2655 gout pts shows that ELEVATED neutrophil-to-lymphocyte ratio (NLR; SMD: 0.75; 95% CI: 0.48–1.03) and platelet-lymphocyte ratio (PLR; SMD: 0.52; 95% CI: 0.24–0.79) showed significant value in predicting acute gout attacks https://t.co/RaArPdoc2s https://t.co/Qi2WDSPlde
