RESUMO
A woman in her 60s with a history of adult-onset Still's disease (AOSD) in remission for 14 years received the ChAdOx1-S vaccine as a booster to her initial vaccination schedule (two doses of CoronaVac vaccine 6 months apart). Two weeks later, she consulted for symptoms suggestive of AOSD reactivation. This was confirmed during hospitalisation, where renal and cardiac involvement were also observed. Despite using high-dose corticosteroids, troponin T and N-terminal pro hormone B-type natriuretic peptide (NT-proBNP) were persistently elevated. Tocilizumab was used, with which the patient achieved complete remission of her symptoms and normalised her laboratory tests.

OBJECTIVE: Our main objective was to assess the relationship between body composition (BC) and response to tumor necrosis factor-α (TNF-α) blocker treatment in patients with ankylosing spondylitis (AS). Our secondary objective was to evaluate the change of BC after treatment, accounting for sex and age. METHODS: All included patients fulfilled the modified New York criteria for AS and were naive to TNF-α blocker. They were followed for at least 6 months after the start of etanercept or adalimumab. The Ankylosing Spondylitis Disease Activity Score containing C-reactive protein (ASDAS-CRP) and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were reported. BC was assessed by whole body dual-energy X-ray absorptiometry. Body fat percentage (BF%), fat mass index (FMI), and fat free mass index (FFMI) were reported as absolute values and as percentiles. RESULTS: Forty-one patients were included (61% men). The median followup was 14.3 months (interquartile range 8.4-19.4). After multivariate regression analysis, more fat at baseline (BF%, FMI, or FMI percentile) was significantly related with a lower chance of achieving a clinically important improvement of the ASDAS-CRP or BASDAI after treatment. The body composition did not change significantly after treatment, but there was a trend toward muscle recovery in men (FFMI change from 34.0th to 37.4th percentile). CONCLUSION: Higher body fat content at baseline was independently associated with a worse response to treatment with TNF-α blockers, measured by ASDAS-CRP and BASDAI change, and might contribute to the lower response rates in female patients. Also, there is a trend toward muscle mass recovery in male patients after treatment.
