Vitamin D Deficiency in End-Stage Renal Disease Patients on Maintenance Hemodialysis

Objective: To determine the frequency of vitamin D deficiency in end stage renal disease patients on maintenance hemodialysis. Study Design: Descriptive Cross-Sectional study. Place and Duration of Study: Department of Nephrology, JPMC, Karachi, from 12th October, 2019 to 11th April 2020. Methodology: One hundred and thirty three patients were enrolled. Venous blood sample of each patient was taken and sent to the laboratory for measuring the vitamin D levels. Serum vitamin D levels <20 ng/ml was taken as vitamin D deficiency. Results: Eighty six (64.7%) were males while 47 (35.3%) were females with mean age was 54.1 +/- 7.8 years, mean duration of ESRD was 11.6 +/- 4.8 months. Vitamin D deficiency was found in 48 (36.1%) patients. Conclusion: The findings of this study support the idea that deficiency of vitamin D is fairly common in end stage renal disease patients on maintenance hemodialysis.
