Obstetric and gynecologic dysfunction in the Ehlers-Danlos syndrome.

Women members of the newly formed Ehlers-Danlos National Foundation (EDNF) were surveyed with a very detailed questionnaire with 50 questions concerning family history and inheritance, past medical history, and obstetric and gynecologic problems. They entailed the largest extant database on Ehlers-Danlos Syndrome (EDS) patients. The mean age of the 68 women who responded to the survey was 42 years; most had EDS types I, III, IV and unknown. Forty-three women had 138 pregnancies; 13 women never married. The stillbirth rate was 3.15% (3/95); the preterm delivery rate was 23.1% (22/95), and the spontaneous abortion rate was 28.9% (40/138). There was a cesarean delivery rate of 8.4%, with 14.7% having perinatal bleeding problems. One woman (EDS type IV) had congestive heart failure. Common gynecologic problems were recurrent anovulation (41.3%), recurrent vaginal infections (53%), abnormal cytologic smears (19%), sexual dysfunction (61%), irregular menses (28%), endometriosis (15.8%), vaginal dryness (25%) and a need for hysterectomy (19.1%). In this largest series of pregnancies with EDS, we found relatively high rates of abortion, preterm delivery, pregnancy-related bleeding and stillbirth. Women with EDS also seem to have high frequency of anovulation, vaginal infections, abnormal cytologic smears and dyspareunia.
