Osteoporosis in primary biliary cirrhosis: effects of 25-hydroxyvitamin D3 treatment.
|
| Abstract |
Bone histology, bone mineral content, and calcium absorption were evaluated in 10 patients with primary biliary cirrhosis and osteopenia, before and after 1 yr of treatment with oral 25-hydroxycholecalciferol. Before treatment, quantitative histomorphometric analysis of full-thickness iliac crest bone biopsy specimens with double-tetracycline labeling demonstrated that 9 of 10 patients had osteoporosis. None had osteomalacia. Fasting intestinal calcium absorption correlated well with trabecular bone volume (r = 0.85). Bone mineral content measured by 125I-photon absorption was low in 6 of 10 patients, and it correlated poorly with iliac crest trabecular bone volume. After 1 yr of treatment with oral 25-hydroxyvitamin D3, bone mineral content fell in all 8 patients who were restudied. Iliac crest trabecular bone volume increased in 3 patients, 2 of whom had the greatest pretreatment impairment in calcium absorption, but fell in 5. Bone fractures continued to occur in 3 of 5 patients who were alive after 1 yr and developed for the first time in a sixth patient. We conclude that 25-hydroxyvitamin D3 is ineffective in reversing the bone thinning in the majority of primary biliary cirrhosis patients, but it may be helpful in a few selected patients.
