Gout flares, serum urate and seasonality: a descriptive cohort study

SU measurement in the year following a gout flare is not indicative of the peak (pre-flare) SU levels that an individual may have experienced. Clinicians should consider this when considering SU measurements in the diagnosis of gout. Patients may find it helpful to be informed of the seasonality of gout flares and advised to take extra caution to reduce the risk of flares during summer months. Keypoints • Serum urate (SU) levels drop precipitously during gout flares and remain low for several months. • Correlations exist between flare rate and summer months, and with seasonal variation in SU levels. • Clinicians should be aware of how gout flares affect SU when interpreting SU levels.
