Abstract

BACKGROUND: Genital endometriosis is one of the most pressing problems of modern gynecology. Melatonin is a promising drug with a potentially curative effect on endometriosis.

AIM: The aim of this study was to conduct a comparative analysis of the genetic polymorphism of some genes encoding enzymes involved in melatonin metabolism.

MATERIALS AND METHODS: The genetic polymorphism in the NAT2 and CYP1B1 genes encoding enzymes involved in melatonin metabolism in patients with different tolerance to this drug was analyzed by PCR-RFLP analysis.

RESULTS: In patients with genital endometriosis, the presence of a wild-type allele (N) of the NAT2 gene was associated with poor tolerance of melatonin. The NAT2 (N / N) rapid acetylator phenotype combined with the low catalytic activity of CYP1B1 (C / C) occurred more frequently in endometriosis patients having poor melatonin tolerability compared to the group of patients who tolerated the therapy well.

CONCLUSIONS: For patients with genital endometriosis with the wild-type (N) allele of the NAT2 gene, melatonin administration is inappropriate due to numerous side effects during the drug use.
