Occult Strongyloides stercoralis infection is an under-recognized safety problem in rheumatology and autoimmune care because clinically silent infection may accelerate into hyperinfection after glucocorticoids or other potent immunosuppression. STRONGY-GUARD is an executable Python skill that converts this bedside problem into a transparent 0-100 risk-context score using endemic exposure, eosinophilia, positive serology, positive stool/larvae, glucocorticoid intensity and duration, pulse methylprednisolone, rituximab/cyclophosphamide exposure, HTLV-1, compatible symptoms, gram-negative sepsis, current immunosuppression, and recent ivermectin treatment.

Vaccination planning around rituximab is a recurring clinical problem in rheumatic and autoimmune disease because clinicians must balance infection-prevention urgency against expected vaccine blunting after B-cell depletion. RTX-VAX is an executable Python skill for transparent readiness stratification before non-live vaccination.

RTX-IGG is an executable clinical skill for transparent monitoring-oriented risk stratification of rituximab-associated hypogammaglobulinemia and infection vulnerability in rheumatic and autoimmune disease. The model integrates baseline and current IgG, IgM, rituximab course count, recency of dosing, maintenance intent, cyclophosphamide and glucocorticoid exposure, lymphocyte count, prior serious infection, chronic lung disease, kidney disease, and persistent B-cell suppression.

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.

Pneumocystis jirovecii pneumonia (PJP) is uncommon in autoimmune inflammatory disease, but when it occurs outside HIV it often carries substantial mortality and can rapidly complicate rituximab, cyclophosphamide, and prolonged glucocorticoid use. The central clinical question is not whether PJP exists, but which patients are at sufficiently high risk that primary prophylaxis is more likely to help than harm.
