  • Title: Bacterial vaginosis.
    Author: Weaver CH, Mengel MB.
    Journal: J Fam Pract; 1988 Aug; 27(2):207-15. PubMed ID: 3042906.
    Abstract:
    Bacterial vaginosis (nonspecific vaginitis) is a polymicrobial, superficial vaginal infection caused by an increase in anaerobic organisms and a concomitant decrease in lactobacilli. Gardnerella vaginalis, once thought to be the sole etiologic agent, is probably one of several endogenous members of the vaginal flora that overgrow in women with bacterial vaginosis. Whether the growth of anaerobes or a primary decrease in lactobacilli is the initial pathogenic event remains unclear. Epidemiological studies have revealed that current or previous infections caused by Trichomonas organisms, increased sexual activity, and intrauterine device use are risk factors for this condition. Studies have indicated that bacterial vaginosis, previously thought to be a benign illness, is associated with some morbidity in pregnant women. Symptoms remain unreliable in the diagnosis of bacterial vaginosis. Diagnostic efficacy is best achieved by utilizing clinical signs. Assessment of cure is best accomplished by Gram stain, not clinical criteria. Metronidazole, 500 mg orally for seven days, remains the treatment of choice; however, a 2-g single dose of metronidazole represents a reasonable alternative if cost and compliance issues predominate in a clinical situation. Although a recent study supports the contention that treatment of the male sexual partner of women with bacterial vaginosis is effective, a general recommendation cannot be made with confidence on the issue of sexual partner treatment until other supporting work is done.
