Objectives. We evaluated platelet counts in end-stage renal disease and chronic viral hepatitis. Materials and Methods. We studied 70 patients with end-stage renal disease and chronic viral hepatitis and compared them to a control group of 45 patients without hepatitis. Results. The presence of viral hepatitis was associated with a higher prevalence of thrombocytopenia. Correlations between age, C-reactive protein, liver stiffness measurement, and platelet count were observed. C-reactive protein levels > 10 mg/dl were associated with a lower risk of thrombocytopenia in patients with end-stage renal disease and chronic viral hepatitis, yet age > 60 years, dialysis vintage > 10 years, aspartate and alanine aminotransferase levels > 20 IU/L, albumin levels < 3.5 g/dl, and fibrosis stage ≥ 3 were not related. Conclusions. Chronic viral hepatitis leads to a higher prevalence of thrombocytopenia. Platelet counts in these patients begin to decrease significantly once liver fibrosis reaches stage III. Keywords thrombocytopenia, end-stage renal disease, chronic viral hepatitis Highlights ✓ Thrombocytopenia is a common occurrence in patients with end-stage renal disease undergoing hemodialysis; ✓ Chronic viral hepatitis B or C in end-stage renal disease patients does not impact platelet counts, suggesting that the natural course of liver disease is slowed in subjects undergoing hemodialysis
