RESUMEN
Renal insufficiency is a risk factor for osteoporosis and can increase risk of fracture. It may be a result of an age-related decline in renal function or chronic kidney disease. In patients with CKD, accurate diagnosis of osteoporosis or CKD-MBD is important for determining the most appropriate treatment. This was a cross sectional study was done at Institute of nuclear medicine and Allied Sciences, BSMMU, Dhaka from 1st January 2014 to 31st December 2014. Study population was total 69 postmenopausal women age over 50 years. Women with Bilateral hip replacement or bilateral hip pins or screws, metallic rods in spine, Carrying out BMD scan within the week after other radiological investigation using contrast media e.g. Barium meals or enema, IVPs were excluded from study. Clinical variables were- age (years), height (cm), weight (kg), BMI. Laboratory variables were- serum creatinine and BMD (Dexa). Estimated GFR was determined by using the serum Creatinine by MDRD formula. Renal function test and Bone mineral density (BMD) were done in all of these patients. Majority (43.4%) of the patients were in 6th decade. The mean weight was found 57.4±11.2kg. Majority 41(59.4%) patients belonged to T score at hip (-1 to -2.5) and their mean T score at hip was found (-1.1±1.1). Osteopenia and osteoporosis were found in 59.4% and 4.3% respectively according to BMD. High serum creatinine level was found in 10.1% cases. Renal function impairment was found in 79.6% of patient. Majority (50.7%) patients had mild decrease of eGFR (60-89 ml/min/1.73m²), There was Pearson's correlation (r=0.156; p=0.200) but not significant was found between age with T score at hip of the patients. Positive Pearson's correlation (r=0.112; p=0.361) was found but not significant between age and serum creatinine level. A significant negative Pearson's correlation (r= -0.274; p=0.023) was found between T score at hip and serum creatinine level of the patients. A significant negative Spearman correlation (r=-0.278; p=0.021) was found between BMD and serum creatinine of the patients. A significant positive Spearman correlation (r=0.580; p=0.001) was found between BMD and estimated GFR of the patients. This study was undertaken to evaluate the relationship between renal function and bone mineral density in postmenopausal women. Majority of the postmenopausal women were in 6th decade and most of them were overweight and obese. Renal function impairment was found in 79.6% of patient. Osteoporosis was found in 04.3% and 20.3% cases according to T score at hip and T score at lumber spine respectively. Significant negative Pearson's correlation was found between T score at hip and serum creatinine level of the patients. Significant negative Spearman correlation was found between BMD and serum creatinine of the patients. Significant positive Spearman correlation was found between BMD and estimated GFR of the patients.
