Taking AI Out of AutoImmunity: Predicting disease before it develops

Akhil Sood, MD Nov 18, 2024

the predictive value of a positive ANA test—especially in the absence of other clinical symptoms—remains a challenge. A positive test often leads to further testing, yet it does not necessarily indicate whether a patient truly has an underlying autoimmune disease. The development of AI and machine learning algorithms presents an opportunity to interpret autoantibody tests and predict autoimmune diseases. Here are three studies looking at this issue.

Dr. @karen_kc123 discusses the results of the VITAL study. - Long term use of Vit D3 2000IU was safe and decreased the incidence of all autoimmune dses by 22%. - It took a while to work but the effect dissipates once discontinued. @RheumNow #ACR24 @rheumarhyme https://t.co/mnwRsdZ06N

A call for ANA stewardship? Abstract 1931: Educating clinicians on wise ANA ordering via EMR Alert plus removing the comprehensive ANA panel --> - ↓ ANA testing (outpatient 15.9%→7.4%, inpatient 25.5%→6.4%) ↓ costs ($440k→$130k) #ACR24 @RheumNow

Study of 25K+ patients using TrinetX on immune checkpoint inhibitors shows no significant mortality difference between those with pre-existing autoimmune disease (AID) and those without. Mortality rates: AID: 39.8% Non-AID: 40.2% Large-scale evidence supports ICIs in AID… https://t.co/BI5jK9jsoM

Mental health, sex, and comorbidities are key factors in determining recalcitrant psoriatic arthritis (PsA). Key findings: - 21.7% of patients required ≥4 biologic/targeted synthetic DMARDs. - Female patients and those with depression were more likely to be recalcitrant. - No… https://t.co/I9YYoRnLwh https://t.co/VtnPceVLOZ
