Risk Prediction Modeling in MDA5 Dermatomyositis
Patients with Melanoma differentiation-associated gene 5 (MDA5) positive dermatomyositis (DM) are complicated and prone to interstitial lung disease, poor prognosis, and a high mortality. A new study suggests a risk prediction… https://t.co/v20ZCVZUQE https://t.co/GmWWQDpWUU

SLE subphenotypes predisposed by distinct genetic risk loci. Multicenter 10 yr genotyping study on 1462 SLE pts (56% w/ lupus nephritis & 43% not LN) found significantly higher polygenic risk scores (PRS); significant LN variants included HLA, TNFAIP3, BLK, & STAT4.… https://t.co/5igpgtdE1U https://t.co/5KOXRThzlk

Severe thrombocytopenia (TP) is rare but linked to major organ involvement and poor prognosis in #SLE. Data from the RISE registry shows TP in 9.3% of SLE patients, with higher prevalence in males, African-Americans+ those with multiple comorbidities.

Study on #SLE and ESRD using machine learning:
Developed model to identify patients with SLE and ESRD
Used NIH 'All of Us' dataset
XGBoost outperformed Random Forest
SDOH data improved model precision #ACR24 @rheumnow #MachineLearning abst#1876 https://t.co/PQ7u4Pj5OH

Abstract 1873: The impact of urbanization on lupus nephritis mortality is complex.
Race/ethnicity + income modify the effects
- Income ≥$50k + living in suburbs associated with lower odds of mortality due to LN in racial/ethnic minorities

Now we have GWAS, we are getting polygenic risk scores for RA, and we can see what disease risks cluster with RA risk.
RA genetic risk clusters with risk for:
type 1 diabetes
thyroiditis
multiple sclerosis
What draws these diseases together?

#1689: race-neutral 🫁 function equations in SSc improve equity:
🔹 Race-specific equations underestimate disease severity in Black patients.
🔹 Switching to race-neutral reclassified 45% of Black patients to more severe, 16% of White patients to less severe

What is my risk of developing SLE?
Abstract 0843 highlights a predictive model that accurately classifies SLE risk using genetics, lifestyle, and environmental factors. Model 3 (genetics + environment + lifestyle) performed the best compared to models 1 and 2.
