The present multicentric study aimed to identify prevalence and determinants of severity of UP among Egyptian patients. Performed investigations included serum urea, creatinine, calcium, phosphorus, parathormone, ferritin and liver enzymes. Pruritus was evaluated using the visual analog scale. The study included 295 patients on maintenance HD. They comprised 151 patients (51.2%) with UP. Independent predictors of UP included associated hypertension (OR: 0.48, 95% CI 0.28 to 0.83, p=0.008), higher calcium levels (OR: 1.29, 95% CI 1.02 to 1.62, p=0.032), higher phosphorus levels (OR: 1.18, 95% CI 1.02 to 1.37, p=0.03) and higher high-sensitivity C-reactive protein (hsCRP) levels (OR: 1.0, 95% CI 1.0 to 1.01, p=0.049). Independent predictors of significant UP included longer HD duration (OR: 1.23, 95% CI 1.1 to 1.38, p<0.001), lack of vitamin D supplementation (OR: 3.71, 95% CI 1.03 to 13.4, p=0.045), lower albumin levels (OR: 0.32, 95% CI 0.14 to 0.74, p=0.008) and higher hsCRP levels (OR (CRP): 1.02 (1.0–1.03), p=0.011). In conclusion, UP is fairly common among Egyptian HD patients. Independent predictors of UP severity include longer HD duration, lack of vitamin D supplementation, lower albumin levels and higher hsCRP levels.Data are available upon reasonable request.
