Misdiagnosis of Still's Disease

Jack Cush, MD

High fever, strange rashes, scary labs often lead to a consideration of Still's disease (AOSD or systemic JIA). Yet the dramatic onset of a systemic disorder may overlap with another, and possibly as rare, systemic disorder that should not be misdiagnosed or mistreated. A current case review by Zhu et al. presents six cases initially diagnosed as systemic JIA, teaching several important lessons.

JAK Safety Debate Continues: Stronger VTE signal, less clear cancer signal

Mrinalini Dey, MBBChir, MA(Hons) Cantab., MRCP, FHEA

Few topics in rheumatology have reshaped prescribing behaviour as dramatically as the safety concerns surrounding JAK inhibitors following ORAL Surveillance and the subsequent FDA and EMA warnings.

Large French nationwide cohort (n=56,591 SpA patients) showed that >6 months/year of targeted therapy exposure was associated with reduced overall cancer risk (wHR 0.86), especially for haematological malignancies (wHR 0.65). Reassuring long-term safety signal. Abstr OP0238

#OP0238: French SNDS cohort found longer exposure to targeted therapies in SpA (>6months) was assoc with a lower overall cancer risk vs shorter exposure, esp for haematologic malignancies. Data add to long-term safety evidence for targeted therapies in SpA. #EULAR2026 @RheumNow

#OP0225 at #EULAR2026: In this nationwide French cohort, patients with IMIDs had nearly 2x risk of HPV-related cancers or severe dysplasia versus matched controls. Risk was particularly increased in SLE, reinforcing the importance of HPV vaccination and screening. @RheumNow

#OP090 at #EULAR2026: In this nationwide Danish study, RA patients with lung cancer had similar survival outcomes to patients without RA. Importantly, immune checkpoint inhibitor treatment did not appear to worsen outcomes in patients with pre-existing RA. @RheumNow

#OP087 explored cancer polygenic risk scores (PRS) in RA. RA was assoc with lower risks of breast and colorectal cancer across all PRS categories, while high prostate cancer PRS may identify RA patients with increased early prostate cancer diagnoses. @RheumNow #EULAR2026 https://t.co/WMqqSFADlW

Cancer risk with JAK inhibitors remains a major focus at #EULAR2026. In #OP086, analysis from 14 international RA registries and >60000 treatment courses found no statistically significant increase in overall or subtype-specific malignancy risk with JAKi versus TNFi. @RheumNow https://t.co/JeOmTufYwo
