Treatment of bone loss in patients with chronic liver disease awaiting liver transplantation

In a retrospective study, we investigated the effect of pre-treatment with oral monthly ibandronate (150 mg), vitamin D3 (800 IU/day) and calcium (1 g/day) for osteopenia and osteoporosis caused by end-stage liver disease in patients before and after liver transplantation (LT).The bone mineral density (BMD) of the lumbar spine (LS) and the femoral neck was measured prospectively pre- and post-LT in 31 patients with existing pre-transplant osteopenia. Patients had osteopenia of the LS prior to LT (T-score ？1.8？±？1.5) so that the treatment medication was initiated immediately after the diagnosis.The study group showed a permanently increased BMD with significant differences (g/cm2) from baseline up to 12 months post LT at the lumbar spine (LS: pre-LT 0.80？±？0.11 g/cm2, three months: 0.90？±？0.08 (P？<0.005); six months: 0.95？±？0.11 (P？<？0.008); 12 months: 1.00？±？0.09 -0.85 (P？<0.012).The combined pre- and post-operative treatment with oral ibandronate had significantly improved bone mineral density of the lumbar spine at 3, 6 and 12 months post LT. The immediate post-operative bone loss after LT can be significantly avoided by pre-treatment of liver transplant candidates affected by osteopenia.
