UNLABELLED: Although endocrine abnormalities are recognized in opiate users, very little is known about the range of hormones affected, their pathophysiology and their clinical relevance. various endocrine abnormalities have been reported in these patients including, increased prolactin levels and abnormalities in sexual hormone. Path physiological mechanism postulated does explain these findings including direct action of heroin or methadone at the hypothalamic pituitary level. The aim of this study was to explore the effects of heroin and methadone maintenance treatment on the plasma prolactin levels and sexual function. MATERIAL AND METHODS: We evaluated 20 male narcotic addicts maintained of methadone more than 3 years on oral high dose methadone 60-120 mgr/day. Patients taking neuroleptic therapy were excluded from the study because neuroleptic-included hyperprolactinemia. We also evaluated group of twenty male heroin addicts on the street heroin .The prolactin plasma levels were assayed using the chemiluminescent immunometric essay (CLIA)--high sensitive methods. The normal range of prolactin levels was 1,5-17 ng/ml (53-360 nmol/l) for men and 1,90-25,0 ng/ml for women. The sexual function was assessed using a Questionnaire: International Index of Erectile Function (IIEF) with 15 items in four levels of sexual function. The differences between two examination groups were determined by a students t test. The results show that street heroin addicts (55% of them have high level of prolactin) have significantly higher plasma prolactin levels (p = 0.006) then the group of methadone maintenance patients (only 15% of them have high prolactin level). In our study, when we compared sexual dysfunction in examination groups in some domains, we did not find statistical significant results (sexual desire p = 0.52 and overall satisfaction p = 0.087). But in domains of erectile function p = 0.011 and orgasm function p = 0.033 we got statistical significant results.
