P0911TO STUDY CHANGES IN BONE MINERAL DENSITY POST RENAL TRANSPLANTATION

Abstract Background and Aims Chronic kidney disease patients get affected by mineral bone disease in view of changes in various biochemical parameters. After transplantation there are changes in these parameters with additional effect of immunosuppression on bone mineral density. My study was to observe changes in biochemical parameters like calcium, phosphorus, vitamin D, parathyroid hormone, alkaline phosphatase and compare bone mineral density with the help of DEXA scan post renal transplantation after 3 and 6 months. It was a prospective observational comparative study. Aim of my study is to evaluate changes in Bone Mineral Density post renal transplantation Method Study was conducted at Apollo Tertiary care Hospital, Hyderabad which caters to rural as well as urban population in southern parts of India. This study was carried out form June 2017 to Dec 2018. Total 40 patients were included in study and they were followed up for the period of 6 months and underwent sets of investigations to assess their bone mineral density. Biochemical variables consist of calcium, phosphorus, alkaline phosphatase, vitamin D level and iPTH. Biochemical variables were classified into hypo, normal or hyper based on their lab values. iPTH values were considered high if value was nine times the upper limit of normal or low if value was less than two times the upper limit of normal. DEXA scan results were classified into normal, osteopenia and osteoporosis based on their t value. Results Study showed that patients who got admitted for transplant belong to age group of 31 – 50 yrs (39.8 +/- 12.8 yrs) predominantly male patients 30 (75%). In 25% patients (10) we were unable to find out native kidney disease shown as CKD (u). Other common causes were DM, ADPKD, CGN or CIN. Most patients were undergoing dialysis for more than 1 year, 47.5% (19) had significant loss of BMD as compared to patients whose dialysis was
