Abstract:
Hemodialysis adequately controls serum uric acid (UA) levels, making UA-lowering drugs unnecessary; scant data are available for peritoneal dialysis (PD). We analyzed blood, 24 h urine and dialysis fluid from twenty patients under PD, to assess UA levels and clearances, and factors associated with better performance and maintenance of target levels (<6mg/dL). Median serum UA was 5.4 mg/dL (p25-75 4.4-5.8), mainly achieved through peritoneal clearance (3.0 mL/min/1.73m2, 71.2% of total UA clearance); 75% of participants was on UA targets. Continuous cycling peritoneal dialysis showed highest UA clearance and target achievements. These findings may be of interest for end-stage renal patients with gout.

One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
