Abstract
Sheehan’s syndrome (SS) is an important cause of pan-hypopituitarism in women. There is scanty information on bone mineral density (BMD) in this condition. We determined BMD and the changes in BMD after oestrogen (E2) replacement and nutritional supplementation in women with SS. In a cross-sectional study, BMD was measured by DEXA in 83 patients [age (mean ± SD) 42 ± 9.2 years] and compared with an equal number of matched controls. In a sub-set of 19 patients, we conducted an open-label, prospective study to determine changes in BMD after 1 year of replacement of E2, and calcium and vitamin D3 supplementation. All patients had low serum IGF-1 and E2, while 98% had ≥ 3 pituitary hormone deficiencies. Compared with Indian reference standards, 47% had decreased bone mass (Z-score ≤ − 2.0). BMD Z-scores were decreased at all sites, being most marked in the lumbar spine and femoral neck. At the lumbar spine, BMD was lowest among the age group 21–30 years. Women with SS also had significantly lower BMD Z-scores at all three sites on comparison with ethnic controls. On multivariate analysis, BMD Z-score was associated with weight, daily calcium intake and age (lumbar spine). In the prospective study, 1 year of therapy improved BMD Z-score at lumbar spine (− 1.4 ± 1.2 vs. − 1.1 ± 1.1, p = 0.02), but not at hip or femoral neck. In conclusion, patients with SS had significantly lower BMD compared to controls at all three sites. Replacement of E2 and supplementation with calcium/vitamin D3 lead to significant improvement in lumbar spine BMD.
