%X <B>BACKGROUND: </B>No meta-analysis has holistically analysed and summarized the effect of prolactin excess due to prolactinomas on bone mineral metabolism. We undertook this meta-analysis to address this knowledge-gap.<BR><B>METHODS: </B>Electronic databases were searched for studies having patients with hyperprolactinemia due to prolactinoma and the other being a matched control group. The primary outcome was to evaluate the differences in BMD Z-scores at different sites. The secondary outcomes of this study were to evaluate the alterations in bone mineral density, bone mineral content and the occurrence of fragility fractures.<BR><B>RESULTS: </B>Data from 4 studies involving 437 individuals was analysed to find out the impact of prolactinoma on bone mineral metabolism. Individuals with prolactinoma had significantly lower Z scores at the lumbar spine [MD -1.08 (95 % CI: -1.57 - -0.59); P < 0.0001; I2 = 54 % (moderate heterogeneity)] but not at the femur neck [MD -1.31 (95 % CI: -3.07 - 0.45); P = 0.15; I2 = 98 % (high heterogeneity)] as compared to controls. Trabecular thickness of the radius [MD -0.01 (95 % CI: -0.02 - -0.00); P = 0.0006], tibia [MD -0.01 (95 % CI: -0.02 - -0.00); P=0.03] and cortical thickness of the radius [MD -0.01 (95 % CI: -0.19 - -0.00); P = 0.04] was significantly lower in patients with prolactinoma as compared to controls. The occurrence of fractures was significantly higher in patients with prolactinoma as compared to controls [OR 3.21 (95 % CI: 1.64 - 6.26); P = 0.0006] Conclusion: Bone mass is adversely affected in patients with hyperprolactinemia due to prolactinoma with predominant effects on the trabecular bone.
