Input: Two trials with 49 participants were included. One trial had low risk of bias. The other trial had high risk of bias. Hormone replacement had no effect on all-cause mortality (RD 0.00; 95% CI -0.11 to 0.11, I² = 0%) and fractures (RD -0.08; 95% CI -0.24 to 0.07, I² = 0%). Hormone replacement significantly increased adverse events and number of patients having hormone replacement withdrawn due to adverse events (RR 5.26; 95% CI 1.26 to 22.04, I² = 0%). Hormone replacement had no significant effect on lumbar spine bone mineral density (MD 1.25 g/cm² yearֿ¹; 95% CI -0.91 to 3.42, I² = 0%). On the other hand, a significant increase in proximal femur bone mineral density was observed in the control group (MD 2.24 g/cm² yearֿ¹; 95% CI 0.74 to 3.74, I² = 0%). Hormone replacement had no significant effect on liver-related mortality, liver transplantation, or liver-related morbidity. Hormone replacement had no significant effect on serum bilirubin concentration (MD 4.60 µmol/L; 95% CI -3.42 to 12.62, I² = 0%). We did not find evidence to support the use of hormone replacement for women with primary biliary cirrhosis. It seems that hormone replacement is connected with a significant increase in the occurrence of adverse events.
Output:

This review assessed the effect of hormone replacement on treatment of osteoporosis in women with primary biliary cirrhosis. We found no evidence of effect of hormone replacement on mortality and fractures in women with primary biliary cirrhosis. It seems that hormone replacement given to women with primary biliary cirrhosis is connected with a significant increase in the occurrence of adverse events compared with placebo or no intervention. Hormone replacement appears to have no effect on the lumbar bone mineral density compared with placebo or no intervention. Hormone replacement may decrease bone mineral density measured at the proximal femur. We did not find evidence to support the use of hormone replacement for osteoporosis in women with primary biliary cirrhosis.
