OBJECTIVE: To assess post-COVID-19 vaccination gout flare risk with differing baseline flare burden.
METHODS: We prospectively studied gout patients with infrequent or frequent flares, defined as ≤1 flare/year or ≥2 flares/year, respectively. COVID-19 vaccine-naive patients managed with urate-lowering therapy between February and June 2021 were included and voluntarily decided on vaccination. Participants were followed for 12 weeks after enrollment or first vaccine dose. Gout flares and risk factors were compared between groups.
RESULTS: Of 530 participants, 308 (58.1%) had infrequent flares and 222 (41.9%) had frequent flares at baseline, with 248 (142 infrequent and 106 frequent) receiving two-dose COVID-19 vaccination. Vaccination increased cumulative flare incidence at 12 weeks in the infrequent but not the frequent flare group (26.1% vs 10.8%, P = 0.001, compared with 60.4% vs 65.5%, P = 0.428). Flare incidence in the final 4 weeks of observation decreased significantly only in the vaccinated infrequent flare group (4.3% vs 12.0%, P = 0.017). Multivariable analyses showed that vaccination (odds ratio [OR] 2.82, 95% confidence interval [95% CI] 1.50-5.30, P = 0.001), flare in the preceding year (OR 1.95, 95% CI 1.03-3.71, P = 0.04), and body mass index (OR 1.09, 95% CI 1.01-1.19, P = 0.03) were independently associated with increased flare risk in the infrequent flare group. Baseline serum urate (mg/dl) was an independent risk factor in the frequent flare group (OR 1.23, 95% CI 1.05-1.45, P = 0.012).
CONCLUSION: COVID-19 vaccination was associated with increased early gout flares only in patients with previously infrequent flares.
