Decrease in Bone Mass in Women After Liver Transplantation: Associated Factors

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Background. In the future, an increasing number of female liver transplant recipients will reach the climacteric with osteoporosis as a common complication. We evaluated the factors associated with decreased bone mass among women after liver transplantation. Methods. A prospective, cross-sectional study of 23 outpatient transplant recipients followed from February 2009 to March 2010 included women of age years after liver transplantations year prior. We recorded patient histories, liver enzyme levels, as well as bone mineral densities measured at the lumbar spine and femur. Statistical analysis used Fisher's exact test, simple odds ratio (OR), and Spearman's rank correlation coefficient. Results. The mean patient age was 52.5 +/- 11 years with 30.4% premenopausal, and 69.6% perimenopausal or postmenopausal. Approximately 21% showed osteoporosis and 35%, a low bone mass. Postmenopausal women: OR 69.0 (95% CI 2.89-1647.18; P = 49 years: OR 13.33 (95% CI 1.78-100.15; P = .0123) and receiving a transplant after 44 years of age: OR 49.50 (95% CI 3.84-638.43; P < .0001) were associated with a lower bone mass. Having undergone transplantation for more than 5.8 years lowered the risk of bone mass change: OR 0.11 (95% CI 0.02-0.78; P = .0361). Clinical and laboratory variables, including corticosteroid use, were not associated with decreased bone mass. Conclusion. Understanding the prevalence and factors associated with osteoporosis among female liver transplant recipients is important to enhance the strategies to diagnose and treat these women, seeking to improve their quality of life.43413511356Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP
