Endometrial histology, microvascular density and caliber, and matrix metalloproteinase-3 in users of the Nestorone-releasing contraceptive implant with and without endometrial breakthrough bleeding.

June 2006
Objective: This descriptive study evaluated endometrial histology, microvascular density and caliber, and quantification of matrix metalloproteinase (MMP-3) expression in long-term users of the Nestorone (NES)-releasing implant who presented or not endometrial breakthrough bleeding (BTB).
Methods: Endometrial biopsies were obtained from 32 healthy women with unpredictable BTB. The quantitative analysis was performed only in 20 samples.
Objective: The objective was to assess endometrial chemokines in users of the levonorgestrel-releasing intrauterine system (LNG-IUS) and correlate them with leucocyte populations, uterine natural killer cells (uNK) and mast cells (MCs).
Materials And Methods: Endometrium was obtained from two groups of women who had been using LNG-IUS for 3 years or more: 11 amenorrhoeic women formed the non-bleeding group and 15 women who maintained some form of cyclic bleeding comprised the bleeding group. Specific antibodies were used for the assessment of neutrophils, uNK cells and MCs.
Correlation between endometrial histology, microvascular density and calibre, matrix metalloproteinase-3 and bleeding pattern in women using a levonorgestrel-releasing intrauterine system.

Background: The main reason for discontinuation of the levonorgestrel-releasing intrauterine system (LNG-IUS) is unpredictable bleeding pattern.
Methods: The objective of the study was to evaluate the endometrial histology, microvascular density and calibre, and the quantification of matrix metalloproteinase (MMP-3) in long-term users of LNG-IUS, with and without bleeding. Endometrial biopsies were obtained from 58 healthy women, 29 who maintained some degree of endometrial bleeding and 29 who were amenorrhoeic.
