Abstract
Zinc is vital for cellular functions, but kidney failure increases zinc deficiency risk. We compared zinc levels in hemodialysis (HD) and peritoneal dialysis (PD) patients in Isfahan, Iran. A retrospective study included 150 patients (75 PD and 75 HD). Serum zinc levels were assessed through photometry. Statistical analysis employed Chi-square, independent t-test, and correlation. Serum zinc was below normal in both groups (P < 0.01). HD patients had lower zinc levels (70.85 ± 7.68 mg/dL) compared to PD (75.04 ± 13.55 mg/dL, P = 0.021), remaining significant after adjusting for confounders (P = 0.011). Zinc levels in PD and HD patients are lower than in the general population, with HD patients having lower levels than PD patients.
