Abstract
OBJECTIVE
To demonstrate the underlying pathogenesis of osteoporosis occurring in patients with lipodystrophy.

METHODS
MEDLINE was searched using the following key terms: lipodystrophy, osteoporosis and reduced bone mineral density. Additional studies were obtained from the bibliographies of reports and reviews above by manual search.

RESULTS
Lipodystrophy is a very rare disease characterized by pathologic alterations in the distribution of adipose tissues in association with a diverse range of metabolic derangements such as hypertriglyceridemia, insulin resistance, diabetes and abnormal bone formation. Reduced bone mineral density has been assessed extensively in HIV-infected patients with lipodystrophy, but far less is known in other lipodystrophy types. This is the first review to discuss the mechanisms of osteoporosis occurrence in various types of lipodystrophy. We herein focus on the cross-regulation of fat and bone and propose that marrow fat accumulation, and reduced serum leptin and adiponectin levels may play an important role in the pathophysiologic process of osteoporosis in patients with lipodystrophy.

CONCLUSION
Osteoporosis is an emerging threat to patients with lipodystrophy. When evaluating the clinical course of a patient with lipodystrophy, osteoporosis should also be considered.
