    Abstract:
    From June 1989 to September 1990, 255 women with recurrent vaginitis, were evaluated, at the "Service of Precocious Diagnosis and Therapy of Gynecological Tumor" of the 1st Department of Obstetrics and Gynecology. They were compared with a control group of 255 women selected in the same time. All patients between the ages of 18-40 years, with normal sexual behaviour, had a negative colposcopy for HPV and HSV2 infections. The cervical smear with Papanicolaou technique and direct immunofluorescence (DIF) was performed in all patients. The specimens were examined with a fluorescence microscope (Leitz). Positive determinations were confined by examination a tha magnification of 600 X. Slides were scored as positive if at least 5 distinct apple-green fluorescence-stained elementary body per field was observed. The two groups were entirely comparable in age, parity, method of contraception, and number of sexual contacts over the preceding three months. Our data confirmed a higher incidence of Chlamydial infections in women with recurrent vaginitis (34.1%) than in control group (8.23%). In symptomatic women, more cases of metaplastic cells with cytoplasmic vacuolation, less inflammatory alteration and a lack of specific agents like CA and TV, were found than in the control group. The DIF positivity, in both groups, was connected with a cytological findings of metaplastic cells with cytoplasmic vacuolation in 72.3% and 50% respectively.
