PREVALENCE OF VITAMIN D DEFICIENCY INPRE-DIALYTIC CHRONIC KIDNEY DISEASE PATIENTS ATTENDING A TERTIARY CENTRE IN NORTH-EAST INDIA

Introduction: Vitamin D deficiency has not only been associated with bone and muscular complications but also with cancer, cardiovascular diseases, infection, maternal and neonatal complications. There are many causes of vitamin D deficiency including socio-demographic factors, the timing of sun exposure, along with drugs, skin, liver, and kidney diseases. India is closer to the equator so is considered to have a lower risk of Vitamin D deficiency but it is not so, with many studies implicating deficiency even in the general population. There are no studies done on the north-eastern Indian population document on vitamin D levels in Chronic Kidney Disease (CKD) patients. Aim: To study the prevalence of Vitamin D deficiency in the pre-dialytic chronic kidney disease. Material and Methods:Observational study was done. 120 CKD patients were included in the study and staging was done according to the MDRD formula. Total 25-OH Vitamin D was measured by the Enzyme Immuno Assay method. Results: 43.33% of the patients in the group were found to have vitamin D deficiency and 26.66% of patients had vitamin D insufficiency. There was a significant association between vitamin D deficiency and stages 4 and 5 CKD. There was not any significant correlation between vitamin D levels with age, sex, body mass index, serum calcium, or albumin. Conclusion:High levels of vitamin D deficiency were seen in the CKD patients of the northeast Indian population. There were statistically significant changes in vitamin D levels and stages 4 and 5 of CKD.
