This non-comparative study evaluated the efficacy, safety, and tolerability of the GnRH analogue buserelin in 52 patients with various stages of endometriosis treated intranasally at 900 mcg/day for 6 months. Disease severity was assessed before and after therapy using pelviscopy and biopsy, with implant regression reported in 88% and mean AFS score decreasing from 17.4 ± 12.9 to 7.2 ± 8.2. Endometriosis-related complaints improved during treatment, but hypoestrogenism effects occurred (e.g., hot flushes in 60%) and bleeding in the first month (40%) decreased over time; laboratory measures remained within normal ranges. The paper’s key limitation is the lack of a comparator group, and it concludes with a follow-up pregnancy rate of 41% among 34 infertile patients. This paper is centrally about endometriosis — it tests buserelin-induced ovarian suppression and reports clinical, biochemical, and pelviscopic outcomes in endometriosis patients.

Abstract

To evaluate the efficacy, safety and tolerance of the GnRH-analogue Buserelin in the treatment of endometriosis, we started a non-comparative study of 52 patients with various stages of endometriosis. The dosage of 900 mcg/d was administered 3 times daily intranasally for 6 months. The degree of the disease was evaluated before and at the end of treatment by pelviscopy and biopsy. A regression of the implant score was found in 88% of patients. The mean AFS score was reduced from 17.4 +/- 1.9 before medication to 7.2 +/- 8.2 after therapy. Endometriosis related complaints were significantly improved during treatment. After 6 months 75% of the patients were without lower abdominal pain, 98% without dysmenorrhoea, and 85% without dyspareunia. As a result of the induced low level of oestrogen, 60% of the patients claimed hot flushes, 12% sweating, reduced libido, and dry vagina. Bleeding (spotting, break-through bleeding, menstruation) occurred in 40% during the first month, and was continuously reduced during the following period. Before, during and after therapy, venous blood samples were drawn to check laboratory tests for blood count, clotting parameters, clinical chemistry, serum electrolytes, as well as liver and lipid metabolism. All values stayed within the normal range without significant changes. In the follow-up period of at least 12 months, we achieved an uncorrected pregnancy rate of 41% in the group of 34 women with primary or secondary infertility.

Der Schweregrad der Erkrankung wurde vor und nach der Behandlung durch Pelviskopie und Biopsie beurteilt. Ein Rückgang der Endometriose-Implantate fand sich bei 88 % der Frauen. Die mittlere Punktzahl des AFS-Score sank von 17,4 ± 12,9 prätherapeutisch auf 7,2 ± 8,2 nach 6monatiger Buserelin-Therapie. Die typischen Endometriose-Beschwerden besserten sich unter der Therapie deutlich. Nach Abschluß der Behandlung waren 75 % der Patientinnen ohne Unterbauchschmerzen, 98 % ohne Dysmenorrhö und 85 % ohne Dyspareunie. Als Folge des Hypoöstrogenismus traten Hitzewallungen bei 60 % der Patientinnen unter der Therapie auf, während 12 % über vermehrtes Schwitzen, Libidoverlust und eine trockene Vagina klagten. Vaginale Blutungen wurden von 40 % der Patientinnen im 1. Behandlungsmonat angegeben, im Laufe der Behandlung nahmen sie jedoch kontinuierlich ab. Vor, während und nach der Therapie wurden Laboruntersuchungen bezüglich des Blutbildes, der Gerinnung, der klinischen Chemie, der Elektrolyte und des Leber- und Fettstoffwechsels durchgeführt. Alle Werte blieben im Normbereich. In der Nachbeobachtungsphase von mindestens 12 Monaten wurde bei den insgesamt 34 Sterilitätspatientinnen eine Schwangerschaftsrate von 41 % erreicht.
