This study found that leuprolide acetate suppressed estradiol and FSH levels in Thai women with endometriotic cysts, leading to amenorrhea and increased vasomotor symptoms in some.

This study investigated serum estradiol (E2) and follicle-stimulating hormone (FSH) levels and vasomotor symptoms in 60 Thai women (ages 15–44) with endometriotic cysts treated with leuprolide acetate 3.75 mg intramuscularly every month for 3 months prior to laparoscopic enucleation. Serum E2 and FSH were measured at baseline and at 1, 2, and 3 months, and vasomotor symptoms were assessed using the Thai version of the Greene climacteric score; the main limitation noted from the abstract is that follow-up was limited to the 3-month treatment window. E2 levels decreased significantly by 1 month, and FSH decreased significantly at 1–3 months; by 3 months, most women had amenorrhea (93.3%) with relatively low use of sedative medication (8.3%) despite higher mean vasomotor symptom scores at 2 and 3 months. This paper is centrally about endometriosis — it studies GnRH analogue–induced suppression of ovarian hormones and resulting vasomotor symptoms in women with endometriotic cysts undergoing preoperative treatment.

Abstract

Background : GnRH analogue can suppress serum estradiol (E2) and follicle stimulating hormone (FSH) to menopause level before laparoscopic enucleation of endometriotic cysts. Objective : To study the levels of E2 and FSH, and vasomotor symptoms after GnRH analogue treatment in Thai women with endometriotic cysts. Materials and Methods : During January, 2006 - December, 2007. Sixty women diagnosed as having endometriotic cysts, aged 15 - 44 years, were recruited into the study. Leuprolide acetate 3.75 mg was given intramuscularly at one month interval for 3 months. Serum levels of E2 and FSH were tested at 0, 1, 2 and 3 months after GnRH analogue treatments. Thai version of Greene climacteric score was recorded at 0, 1, 2 and 3 months. Results : The median (25th percentile, 75th percentile) of serum E2 level decreased significantly from the baseline (0 months: 232.3 (82.0,446.2) pmol/L vs. 1 months : 18.4(0,44.9) pmol/L, 2 months: 31.7(0,58.6) pmol/L, 3 months: 0(0,54.2) pmol/L). The median (25th percentile, 75th percentile) of serum FSH level decreased significantly from the baseline at 1,2 and 3 months. (0 months: 4.8(3.1,7.0) IU/L vs. 1 months: 2.2(1.3,3.5) IU/L, 2 months 2.8 (1.8,5.2) ,3 months 3.0(2.8,4.9) IU/L). Only 8.3% of women required sedative medication for vasomotor symptoms relief. The mean vasomotor symptoms scores were significantly higher than the baseline at 2 and 3 months period (0 months: 14.5 vs. 2 months: 20.0 and 3 months: 20.2). Most women had amenorrhea at 3 months period (93.3%). Conclusion : Leuprolide acetate can suppress ovarian function after the first month of injection. Most women can stand the vasomotor symptoms. Amenorrhea was the most common menstrual patterns at 3 months after injection.
