Inclusion criteria

Inclusion criteria: Adult patients 18 years and older Hyperuricemia with serum uric acid level = 7 mg/dL Having written informed consent to participate in the study Previously untreated patients or those currently receiving stable doses of allopurinol or febuxostat prior to enrollment

Design outcomes

Primary

MeasureTime frame
Time to reach target uric acid level of less than 6 mg/dL. Timepoint: At the beginning of the study (before the intervention) and 2 months after the intervention. Method of measurement: Serum uric acid levels were measured from venous blood samples after at least 8 hours of fasting.

Secondary

MeasureTime frame
Frequency and severity of gout flare-ups. Timepoint: Before and 3 months after the intervention. Method of measurement: The frequency of gout flares was recorded based on the number of acute attacks reported by the patient during the follow-up period. The severity of each attack was measured using a numerical pain scale (VAS from 0 to 10) and clinical assessment of joint inflammatory symptoms by the attending physician.
