Nandrolone Decanoate in the Treatment of Telomeropathies

Summary

Decrease in blood cell counts due to deficient bone marrow function, called bone marrow failure, as well as some lung diseases, called idiopathic pulmonary fibrosis, can be caused by genetic defects in telomere biology genes, eventually causing telomere erosion. These disorders are collectively termed "telomeropathies". There is evidence that male hormones may improve blood cell counts in marrow failure, and these hormones are able to stimulate telomerase function in hematopoietic cells in vitro. We propose this study to the use of male hormone in patients with aplastic anemia and pulmonary fibrosis associated with defects in telomeres.
