Background: Kidney transplant recipients are known to have bone disease, specifically osteoporosis. In this descriptive clinical study we aimed to evaluate the incidence of osteoporosis and to determine the risk factors among our transplant recipients.
Methods: A total of 109 patients (82 males and 27 females) aged from 19 to 70 years, who had undergone kidney transplantation 12 to 69 months previously, were included in the study. Bone mineral densitometry was performed using dual-energy X-ray absorptiometry. The correlation between femur and lumbar spine T-scores with age, gender, posttransplantation duration, serum 25 hydroxy vitamin D, parathyroid hormone, calcium, phosphorus, creatinine, and hemoglobin values were investigated.
Results: The incidence of osteoporosis was 22% (24 of 109 patients). The most common sites of osteoporosis were the femur (osteoporotic in 17 patients [15.5%] and osteopenic in 57 [52.2%]) and the lumbar spine (osteoporotic in 24 patients [22%] and osteopenic in 50 [45.8%]). Osteoporosis was found to have no relationship with age and gender. There was a significant negative correlation between serum parathyroid hormone levels with both femur and lumbar spine T-scores (P = .013 and .033, respectively). However, serum phosphorus levels were negatively correlated with only femur T-scores (P = .037). A positive correlation of hemoglobin with lumbar T-scores and a negative correlation with posttransplantation duration (P = .038 and .012, respectively) were also observed.
Conclusion: Bone disease after transplantation is a frequent complication, which may decrease the quality of life, so we believe it is important to reduce the morbidity; it is required to detect and correct the risk factors of this complex pathophysiological situation.
