Studying Risk Factors Association with Osteoporosis in Post Kidney Transplantation Patients

Osteoporosis that associate with kidney transplantation is an important cause of ‎morbidity to ‎the patients that warranted extensive study about possible causes of ‎osteoporosis in order to ‎implement several steps to reduce this risk. The current work aimed to investigate possible association between post kidney ‎transplant ‎immunosuppression therapy type and developing the ‎osteoporosis and evaluate the bone mass by using dual X-ray absorptiometry (DXA) post-renalal transplant. A case-control, conducted in kidney transplant center – medical city complex for ‎one year period (‎from October ‎‏2018‏‎ till April 2019), Seventy - five kidney ‎transplant patients were participated in the present study ‎including (21 females & ‎‎54 males). All ‎patients were examined for their bone density using DEXA scan (T – score) and ‎those with cut – point ≤- 2.5 were diagnosed as having osteoporosis (lumber and ‎hip bones were examined). The prevalence of osteoporosis and osteopenia was significantly higher in ‎transplant patients compared to control for bone lumber and hip bone (for ‎lumber bones: 33.3% vs 2.7%l for hip bones: 60% vs. 14.7%). T score was ‎significantly lower in the transplant patients compared to control for both lumber ‎‎(-1.9‎±0.8 vs. -1.1‎±0.7) and hip bones (-2.3‎±0.9 vs -1.3‎±0.8).‎ In logistic regression analysis; only gender and BMI were the predictors of ‎osteoporosis for spinal bone, while; the BMI and calcium were the predictors ‎of osteoporosis for hip bones. In ‏conclusion, Osteoporosis in post-renal transplant patients have a high rate of ‎osteoporosis compared to the general population, post-renal transplant drugs (Cyclosporine, MMF, etc.) did not increase the ‎risk of osteoporosis, and body mass index and female gender were risk factors for osteoporosis
