title: Longitudinal evaluation of serum estradiol and estrone in male patients infected with the human immunodeficiency virus.
abstract: In patients with human immunodeficiency virus (HIV) infection alteration of various endocrine functions have been described. However, there is limited information available on estrogens and their function in these patients. The aim of this study was to evaluate the pituitary and testicular endocrine markers: 14 HIV-positive men were included into the longitudinal study with a follow up to of 18 month period. None of the patients had a history or clinical evidence of endocrine dysfunction. Follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin, estrone, estradiol, and testosterone were measured in serum by commercially available radioimmunoassays. Prolactin levels were not affected in the patients. LH and FSH remained within normal range, but at the end of the study period we observed a significant increase of LH (p < 0.05). In addition, testosterone levels were normal with a slight reduction at the end of the 18-month observation period (p <0.05). Both estrone and estradiol were significantly increased with a further rise at the end of the study (p <0.05). In summary, the elevation of the serum estrone and estradiol in HIV-afflicted patients correlated with the progress of the HIV-disease, being paralleled by a decrease in testosterone. The altered relation of estrogens and testosterone may in a part be responsible for the complaints of decreased libido and increased impotence often observed in HIV-infected men.
