Hyperparathyroidism is common in long-term transplant recipients, findings suggest.
Researchers at the University of Nebraska Medical Center in Omaha reported data on 28 kidney transplant recipients (mean age 54 years) screened so far in an ongoing study. At the time of screening, the patients had their allografts for a mean of about five years.
Hyperparathyroidism was present in 71% of patients, according to investigators. Their mean parathyroid hormone concentration was 104.3 pg/mL. Vitamin D deficiency (defined as a 25-hydroxyvitamin D level below a target value of 30 ng/mL) was observed in 68% of participants, and was the most common cause of hyperparathyroidism identified.
