Abstract

Abstract

Objective: To assess the frequency of Vitamin D Deficiency and its association with serum Parathormone (PTH) levels in End stage renal disease patients in our tertiary setup.

Methods: This cross sectional study was conducted in the Department of Nephrology, Liaquat National Hospital from January to December 2016 and comprised of End stage renal disease on maintenance hemodialysis. Sample size of 113 at 8% prevalence was calculated inflated to 150. Participants were selected through purposive sampling technique. Numerical variables were expressed as mean +/- SD (standard deviation) while categorical variables were expressed as frequency and percentages. To determine association between Vitamin D and serum Parathormone (PTH) levels chi-square test was applied. Association of serum alkaline phosphatase levels with both Vitamin D levels and PTH levels was analyzed using chi-square test. SPSS 20 was used for data analysis. P-value <0.05 was taken as significant.

Results: Of the 150 participants, 33 were drop outs, 63(53.8%) were males and 54(46.2%) were females. The overall mean age was 52.47+15.21. Of all, hypertension as a comorbidity was present in 64(54.7%), Diabetes mellitus was present in 8(6.8%) and cardiovascular disease in 7(6%). Among the biochemical markers, mean serum vitamin D levels were 18.6+13.6ng/ml, mean Serum PTH levels were 253.8+227.2pg/ml, mean serum alkaline phosphatase levels were 143.7+125.4µg/L, mean serum phosphorus levels were 4.81+3.46mg/dl and mean serum calcium levels were 21.41+114.4mg/dl. Among the study participants, 67(57.3%) were found to be Vitamin D deficient.
