OBJECTIVE: To record the effect of pyrazinamide on uric acid in patients of tuberculosis. DESIGN: Descriptive and observational study. PLACE AND DURATION OF STUDY: Chandka Medical College Hospital, Larkana from February 2000 to January 2003. PATIENTS AND METHODS: All patients receiving anti-tuberculosis drugs with pyrazinamide were included. Serum uric acid levels were monitored at weeks 0, 2, 8 and 12 of therapy. Serum creatinine was done at weeks 0, 8 and 12. RESULTS: Results were reported on 216 patients. Mean uric acid and creatinine levels at the start of therapy, i.e., week '0' were 5.07 -/+ 0.57 mg/dl and 0.87 -/+ 0.11 mg/dl respectively. The results show significant increase in uric acid levels from week '0' to week '2', at the end of week '8', the levels remained elevated and there was no statistical significant difference from that at week '2'. The uric acid levels reduced at week '12' after pyrazinamide was stopped and the difference was significant. Despite that renal function steadily improved with the treatment of tuberculosis to the extent that comparable pre-treatment values were obtained at the end of treatment. CONCLUSION: Anti-tuberculous therapy with pyrazinamide affects the uric acid levels early. This change is reversible after the withdrawal of the agent.
