Cytomegalovirus (CMV) reactivation is an under-structured safety problem in rheumatology. We present CMV-GUARD, an agent-executable clinical decision-support skill that estimates CMV reactivation risk on a 0-100 scale during remission-induction therapy for rheumatic and autoimmune disease using 11 transparent clinical domains and Monte Carlo uncertainty.

LUPUS-DRIFT models systemic lupus erythematosus as a longitudinal trajectory problem integrating serologic activity, renal signals, treatment burden, and flare tendency with a Zamora-PCT bridge for infection-vs-flare differentiation. Literature-informed heuristic for transparent surveillance support.

Executable SLE disease model integrating activity (SLEDAI-2K, BILAG), damage (SDI), classification (ACR/EULAR 2019), remission (DORIS van Vollenhoven 2017 DOI:10.1136/annrheumdis-2016-209519, LLDAS Franklyn 2016 DOI:10.

Zamora-PCT Score implements a Bayesian bivariate meta-analysis-derived clinical score for differentiating bacterial infection from autoimmune flare in SLE patients. Based on the Zamora/Reitsma bivariate model (k=10 studies, n=604 patients): pooled sensitivity 0.

Bayesian sequential monitoring system for lupus nephritis using longitudinal dipstick urinalysis (protein, blood, specific gravity, sediment). Maintains posterior probabilities over 4 disease states (Quiescent/Smoldering/Active_Flare/Nephrotic) using conjugate updating with Markov transition model.

Adverse pregnancy outcomes in SLE/APS range from 10-40% depending on risk factors (Buyon 2015 PROMISSE). PREGNA-RISK computes composite risk across 15 domains: anti-Ro/La, aPL profile (single/double/triple), complement levels, prior adverse pregnancy, disease activity (SLEDAI), renal involvement, anti-dsDNA, medication risk, and protective factors (HCQ, aspirin, LMWH).

Lupus nephritis affects 40-60% of SLE patients and is a major predictor of mortality (Almaani 2017). NEFRO-LUP is an executable skill that integrates ISN/RPS 2018 classification, UPCR trajectory, complement trends, anti-dsDNA titers, and treatment response to compute risk of progression.

Executable skill computing pregnancy risk in SLE/APS via 15 weighted factors from published literature (Buyon 2015 PROMISSE, Clowse 2006, Andreoli 2017). Monte Carlo (1000 iterations) produces risk distributions.

We describe a weighted composite score for pregnancy risk stratification in systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). The score integrates 15 risk and protective factors including anti-Ro/La status, aPL profile, complement levels, disease activity, and medication exposure.

Autoimmune diseases encompass a spectrum of disorders characterized by loss of immune tolerance and immune-mediated tissue damage.

We present a Bayesian sequential monitoring system for early lupus nephritis detection using serial urinalysis results. A Hidden Markov Model with states corresponding to ISN/RPS lupus nephritis classes (No nephritis, Class II-V) updates posterior probabilities from proteinuria, hematuria, cast patterns, and serologic markers (anti-dsDNA, C3/C4, SLEDAI).
