Osteoporosis is a prevalent finding in patients with solid organ failure awaiting transplantation - a population based study.
Post-transplant bone disease is common in solid organ recipients; however, there is limited information on their pre-transplant bone status. We aimed to compare bone mineral density (BMD) in different categories of patients with end-stage organ failure awaiting transplantation (Tx) in Norway. Overall 291 adult patients were enrolled, including 60, 84, 81 and 66 patients with end-stage lung, liver, kidney and heart failure, respectively. Mean age was 51 ± 12 yr with no significant differences between the groups. We measured BMD in lumbar spine, femur, proximal one third and ultra-distal radius by dual energy X-ray absorptiometry. Differences in T- and Z-scores between the groups were compared by ANOVA. Low bone mass was found in all four groups of patients. Both T- and Z-scores differed (p < 0.05) at all measured sites between the groups. Patients with lung failure had the highest prevalence of osteoporosis (67%) and lowest Z-scores, followed by patients with liver (31%), kidney (24%), and heart (23%) failure. Osteoporosis is prevalent in all groups of organ transplant candidates, and poor bone health is remarkably pronounced in patients with chronic lung disease. General practitioners and specialists who care for these patients before they are referred for transplantation should consider measures to prevent osteoporosis at an earlier stage.
