Abstract:Objective To study the effects of peritoneal dialysis and hemodialysis on microinflammation and gout attack in patients with uremia complicated with hyperuricemia. Methods Totally 98 patients with uremia complicated with hyperuricemia were enrolled, including 51 patients undergoing hemodialysis (HD group) and 47 patients receiving peritoneal dialysis (PD group). All patients were followed up for 6 months. According to whether the patient had acute gouty arthritis, patients were divided into seizure group (group A) and non-seizure group (NA group); according to the number of occurrences, it is divided into four levels: 0 time, 1 to 2 times, 3 to 4 times, ≥5 times. The levels of microinflammatory factors were compared between HD group and PD group, A group and NA group; and the number of patients with acute gouty arthritis in HD group and PD group were compared. Results After 6 months of follow-up, the level of microinflammation factor in PD was significantly lower than that in HD group (P?0.05). The average level of microinflammation factor in group A was higher than that in group NA (P?< 0.05). The incidence of acute gouty arthritis in PD group was lower than that in HD group, and the difference was statistically significant (P?0.05). Conclusion Peritoneal dialysis can reduce the risk of acute gout in patients with uremia complicated with hyperuricemia compared with hemodialysis. The possible mechanism is that the level of microinflammation in peritoneal dialysis patients is much lower than that in hemodialysis patients.
