Fascinating: tDR-1, a microbial sRNA, appears protective for RA in at risk ACPA+ pts:
- tDR-1 higher = less develop RA
- can predict seropos RA development
- in vitro type 1 IFN mapping checks out
Useful in itself, but importantly: why does it happen?

tRNA-derived RNA (tDR-1), circulating microbial RNA
Associated w/ reduction in risk of RA conversion in asymptomatic CCP+ individuals (60 vs. 120+ ctrls),
‼️ tDR-1 alone over performs prediction model w/ smoking shared episode and RF w/ AUC 0.86
What is the mechanism? tDR-1 https://t.co/fuyk4NeOyA

What can we learn from longitudinal peripheral blood multi-omic profiling in at-risk individuals?
50 RA converters vs. non converters from StopRA study

#0774
Multi-omic profiling of anti-CCP3+ “at-risk” individuals reveals Tph & cytotoxic CD8+ expansions, altered gene/chromatin profiles and predictive model (AUC 0.77) for RA conversion
PTPN22 locus accessibility & Tph ≥ 2.45% identify highest risk. @RheumNow #ACR25 https://t.co/JDSMkdmoGv

A new marker for stratification of ILD in dermatomyositis: Anti MDA5 antibodies!
Japanese study
MDA5 (201-300) positivity associated w/
Lower 6-month progression-free survival (43% vs. 74%)
Lower 5-year survival rates (34% vs. 66%)
Validation in other populations awaited https://t.co/IBiYyATer4

Clinical and Genetic Effects of Neuropsychiatric Lupus
The clinical features and genetic abnormalities of neuropsychiatric systemic lupus erythematosus shows that NPSLE often means more severe lupus and more organ involvement beyond the central nervous system. https://t.co/7Ujo6Kaf1N

Sequencing DNA to find new lupus treatments
MUSC geneticist Betty Tsao, Ph.D., will lead a five-year project to identify rare mutations associated with childhood-onset SLE, or lupus, with more than $3.5 million in funding from the National Institute of Arthritis and https://t.co/1vfQ4fK6FX

HLA-B27: still the most important genetic factor in axSpA susceptibility, but has lower frequency African American, South American & Middle Eastern pop. B27 discerns clinical subsets of SpA and PsA, particularly acute anterior uveitis or axSpA with psoriasis, https://t.co/S4s0NvuwNY

Inception SLE study of 674 pts (without LN), mean age 34 yrs - 154 (23%) developed new proteinuria (LN) after median of 3.6 yr. Cumulative antimalarial exposure did NOT lower risk of LN (HR 0.98; 0.94-1.02); same for those w/ serologically active SLE (HR 0.97) https://t.co/8OU3yJAvhN

Juvenile Lupus: some new mechanistic data
Circulating Treg population are expanded in SLE and in particular in Lupus Nephritis compared to HC
Naive Treg display specific molecular features in particular over expression of FCRL3 and TLR5 showing new pathways to explore in https://t.co/RuMtWRkpYB

Italian Systemic sclerosis (SPRING-SIR) registry - 1157/1538 (75%) SSc pts were in menopause, 632 (50%) had pre-menop SSc onset, 130 (14.4%) had early menopause. Post-menop. had more CREST, centromere Abs, ILD & GI Sxs. Pre-menop. had more diffuse Dz & peripheral vasculopathy. https://t.co/Jz2v5CkH0Y

Interesting data shared by Dr. Sandhya Pulukool on Asian pts with SjD vs. Caucasians:
- Younger age of onset except in Japan
- Higher female to male ratio

Peter Taylor on Pre-RA:
If Pre-RA is too late for interception, shall we start screening general population?
We have to remember RA is a RARE disease
Pre-test of RA per year per person would be 0.00025% for primary prevention:
A needle in a haystack?

Prof Takeuchi on DMARDs treatment and regional disparities
For similar dose, serum concentration of the polyglutamate (active) form of MTX is much higher in Japanese than US patients
And also high levels achieved much quicker in Japanese than US patients
This is strong https://t.co/ikp63wWifj

MUC5 mutations not in SSc-ILD. Study of 2363 SSc-ILD, 3526 SSc w/o ILD & 15076 controls. They found no assoc w/ MUC5B promoter variant & SSc-ILD. (Suggesting ILD pathogenic mechanisms differ between RA and SSc) https://t.co/bBq52X0Mwq https://t.co/eu1IpaXGL8
