ABSTRACT
Bone disease and an high risk of fractures are major problems in transplantation. Among
diabetic patients undergoing simultaneous kidney–pancreas (SKP) transplantation, there
are few studies assessing long-term effects on bone mass. The aim of this study was to
evaluate bone mineral density (BMD) over 4 years follow-up after SKP transplantation.
Fifty-seven patients had 22.8 5.3 years of prior diabetes, 65% were female, and the
overall mean age was 24.3 5.93 years. At the time of transplantation, the lumbar spine
and femoral neck T-scores were 1.75 1.05 and 1.95 0.73, respectively; 28% of
subjects had evidence of osteoporosis. One year after transplantation, 77.6% of patients
displayed improved lumbar T-scores to 1.33 0.94 (.044) with stable femoral neck
T-scores. Bone densitometry enhanced gradually through the 4 years follow-up: lumbar
T-score to 1.04 0.67 (.004) and femoral neck T-score to 1.69 0.49 (.12).
At year 4, no osteoporosis cases were detected but 86.7% of patients did not receive
steroids in the immunosuppressive regimen. The graft function remained stable (serum
creatinine, 1.2 mg/dL; fasting glucose, 87.7 mg/dL). During the follow-up, BMD improved
more significantly at cortical sites. Our study reports a reduced prevalence of fractures
(8.7%) compared with the literature, which could be related to a steroid-sparing protocol
and/or aggressively treatment of osteoporosis.
