[Dyspareunia and Sjögren's syndrome].

BACKGROUND

Dyspareunia is frequently associated with a psychiatric origin, particularly in patients with no obvious vulvovaginal or pelvic disease. The aim of this study was to assess the frequency of dry syndrome in patients with dyspareunia and to evaluate the main clinical and biological features and follow-up data for women with dyspareunia and dry syndrome.

PATIENTS AND METHODS

Twenty-two patients presenting chronic idiopathic dyspareunia (without clear vulvovaginal dermatosis or infection) were included in this retrospective study. All patients underwent history-taking, gynecological examination, a Schirmer tear test, a sugar test, labial salivary gland biopsy assessment and immunological examination. A diagnosis of Sjögren's syndrome was considered where histological examination of the salivary glands showed a lymphocyte infiltration corresponding to stage 3 or 4 in the Chisholm classification. Diagnosis of dry syndrome without Sjögren's syndrome was made in patients with xerostomia and/or xerophthalmia without a specific histological picture of Sjögren's syndrome or immunological abnormalities at salivary gland biopsy.

RESULTS

Based on our criteria, 10 patients (45%) had dry syndrome, including 4 with Sjögren's syndrome and 6 with dry syndrome without Sjögren's syndrome. 9 of these 10 patients presented either xerostomia (7 cases) and/or xerophthalmia (7 cases). Vaginal dryness was reported by 3 of the 10 women with dry syndrome but also by 4 of 12 women without dry syndrome. Examination of the vulva showed no particular clinical features and treatment with an emollient was not effective in all cases.

DISCUSSION

This study showed a high frequency of dry syndrome in patients with chronic "idiopathic" dyspareunia. The incidence of the condition was even greater in women with functional conditions evocative of dry syndrome. Women presenting dyspareunia with no clearly related clinical causes should thus be carefully assessed for dry syndrome.
