In healthy hands and feet, Doppler signal was rare at any age, but grey-scale findings were not
An OMERACT study of 802 healthy adults sets age- and joint-specific normal ranges for small-joint ultrasound. Plus autoimmunity in Klinefelter syndrome, and who gets cytokine release after CAR-T.
The edition in brief
An international OMERACT study scanned the hands, wrists and feet of 802 healthy adults aged 18 to 80. Doppler signal was minimal in every joint and age group, so Doppler in these joints is likely to be abnormal at any age; grey-scale findings were common, especially in the first and second metatarsophalangeal joints (45% and 39% had some finding), and normal thresholds for synovial hypertrophy and effusion varied by joint and age. A meta-analysis of 2,289 men with Klinefelter syndrome found very high odds of clinically manifest autoimmune disease (OR 48), mostly lupus, Sjögren's, systemic sclerosis, thyroid disease and type 1 diabetes, from a small, heterogeneous evidence base. In 108 patients given CAR-T for autoimmune disease, 80% had cytokine release syndrome, nearly all grade 1–2; higher baseline B-cell counts and IL-6 were associated with it. The pearl covers when to think of lupus in a man.
Men with Klinefelter syndrome had markedly higher odds of autoimmune disease
Think of autoimmunity in men with Klinefelter syndrome, and of Klinefelter in men with lupus-spectrum disease.
After CAR-T for autoimmune disease, most had mild cytokine release, predicted by B cells and IL-6
Expect mild cytokine release after CAR-T for autoimmune disease, and flag high B-cell counts and IL-6 at work-up.
When to think of lupus in a man
Check ANA and urine early in men with unexplained serositis, cytopenias or proteinuria.
Doppler in small joints was rare in healthy people at any age; grey-scale findings were common
Read Doppler in small joints as abnormal at any age, but judge grey-scale findings against joint- and age-specific norms.
