          Abstract

          OBJECTIVE: To determine the recurrence of bacterial vaginosis (BV) after the use of a lactic acid plus lactoserum liquid soap starting immediately after the treatment with oral metronidazole and the quality of life of the participants. METHODS: A total of 123 women with diagnosis of BV with at least three of the following criteria: 1) homogeneous vaginal discharge without inflammation of the vagina or vulva; 2) vaginal pH ≥ 4.5; 3) positive Whiff test; and 4) "clue cells" in more than 20% of the epithelial cells in the vagina. A Nugent score ≥ 4 in the vaginal bacterioscopy was also used. After BV diagnosis, metronidazole 500 mg was administered orally bid during 7 days. Patients cured of BV were then instructed to use 7.5 to 10 mL of a lactic acid plus lactoserum liquid soap once-a-day for hygiene of the external genital region. Three subsequent control visits after starting the hygiene treatment (30, 60, and 90 days; ± 5 days) were scheduled. A questionnaire was applied in the form of visual analogue scale (VAS) in all the visits regarding: 1) level of comfort at the genital region; 2) malodorous external genitalia; 3) comfort in sexual intercourse; 4) satisfaction with intimate hygiene; and 5) self-esteem. RESULTS: Ninety two (74.8%) women initiated the use of a lactic acid plus lactoserum liquid soap at visit 1. At visit 2, 3, and 4 there were 84, 62 and 42 women available for evaluation, respectively. The rate of recurrence of BV was 19.0%, 24.2% and 7.1%, respectively in the three visits and vaginal candidiasis was observed in five treated women. Quality of life was evaluated in the 42 women who completed the four visits schedule and there were significant improvement in the five domains assessed. CONCLUSION: A lactic acid plus lactoserum liquid soap for external intimate hygiene may be an option for the prevention of BV recurrence after treatment and cure with oral metronidazole

          OBJETIVO: Determinar a ocorrência de vaginose bacteriana (VB) após o uso de acido láctico com lactoserum em sabonete líquido iniciado imediatamente após o tratamento com metronidazol oral e qualidade de vida das participantes. MÉTODOS: Um total de 123 mulheres com dianóstico de VB com ao menos três dos seguintes critérios: 1) leucorreia vaginal homogênea sem inflamação de vagina ou vulva; 2) pH vaginal ≥ 4,5; 3) teste positivo de Whiff; e 4) "clue cells" em mais de 20% das células epiteliais na vagina. O escore de Nugent ≥ 4 na bacterioscopia vaginal também foi usado. Após o diagnóstico de VB, metronidazol 500 mg oral foi ministrado durante 7 dias. Pacientes curados da VB foram instruídos a usar 7,5 a 10 mL de acido láctico com lactoserum em sabonete líquido uma vez ao dia para higiene da genitália externa. Três visitas de controle foram agendadas (30, 60 e 90 dias; ± 5 dias). Um questionário foi aplicado na forma de escala visual análoga (EVA) em todas as visitas sobre: 1) nível de conforto na região genital; 2) mau odor na genitália; 3) conforto na relação sexual; 4) satisfação com higiene íntima; e 5) autoestima. RESULTADOS: Noventa e duas (74,8%) mulheres iniciaram o uso de ácido láctico com lactoserum líquido na visita 1. Na visita 2, 3 e 4 foram 84, 62 e 42 mulheres para avaliação, respectivamente. A taxa de recorrência da VB foi 19,0%, 24,2% e 7,1%, respectivamente nas três visitas e candidíase vaginal foi observada em cinco mulheres. Qualidade de vida foi avaliada em 42 mulheres que completaram as quatro visitas agendadas e houve uma melhora significativa nos cinco domínios avaliados. CONCLUSÃO: O uso de acido láctico com lactoserum em sabonete líquido para higiene externa intima pode ser uma opção para a prevenção da recorrência de VB após tratamento e cura com metronidazol oral

          Reliability of diagnosing bacterial vaginosis is improved by a standardized method of gram stain interpretation.

          The purpose of the study was to examine intercenter variability in the interpretation of Gram-stained vaginal smears from pregnant women. The intercenter reliability of individual morphotypes identified on the vaginal smear was evaluated by comparing them with those obtained at a standard center. A new scoring system that uses the most reliable morphotypes from the vaginal smear was proposed for diagnosing bacterial vaginosis. This scoring system was compared with the Spiegel criteria for diagnosing bacterial vaginosis. The scoring system (0 to 10) was described as a weighted combination of the following morphotypes: lactobacilli, Gardnerella vaginalis or bacteroides (small gram-variable rods or gram-negative rods), and curved gram-variable rods. By using the Spearman rank correlation to determine intercenter variability, gram-positive cocci had poor agreement (0.23); lactobacilli (0.65), G. vaginalis (0.69), and bacteroides (0.57) had moderate agreement; and small (0.74) and curved (0.85) gram-variable rods had good agreement. The reliability of the 0 to 10 scoring system was maximized by not using gram-positive cocci, combining G. vaginalis and bacteroides morphotypes, and weighting more heavily curved gram-variable rods. For comparison with the Spiegel criteria, a score of 7 or higher was considered indicative of bacterial vaginosis. The standardized score had improved intercenter reliability (r = 0.82) compared with the Spiegel criteria (r = 0.61). The standardized score also facilitates future research concerning bacterial vaginosis because it provides gradations of the disturbance of vaginal flora which may be associated with different levels of risk for pregnancy complications.

            Vaginal lactobacilli, microbial flora, and risk of human immunodeficiency virus type 1 and sexually transmitted disease acquisition.

            A prospective cohort study was conducted to examine the relationship between vaginal colonization with lactobacilli, bacterial vaginosis (BV), and acquisition of human immunodeficiency virus type 1 (HIV-1) and sexually transmitted diseases in a population of sex workers in Mombasa, Kenya. In total, 657 HIV-1-seronegative women were enrolled and followed at monthly intervals. At baseline, only 26% of women were colonized with Lactobacillus species. During follow-up, absence of vaginal lactobacilli on culture was associated with an increased risk of acquiring HIV-1 infection (hazard ratio [HR], 2.0; 95% confidence interval [CI], 1.2-3.5) and gonorrhea (HR, 1.7; 95% CI, 1.1-2.6), after controlling for other identified risk factors in separate multivariate models. Presence of abnormal vaginal flora on Gram's stain was associated with increased risk of both HIV-1 acquisition (HR, 1.9; 95% CI, 1.1-3.1) and Trichomonas infection (HR, 1.8; 95% CI, 1.3-2.4). Treatment of BV and promotion of vaginal colonization with lactobacilli should be evaluated as potential interventions to reduce a woman's risk of acquiring HIV-1, gonorrhea, and trichomoniasis.

              High recurrence rates of bacterial vaginosis over the course of 12 months after oral metronidazole therapy and factors associated with recurrence.

              We wished to determine recurrences of bacterial vaginosis (BV) after treatment over the course of 12 months and to establish factors associated with recurrence. Women with symptomatic BV (a Nugent score [NS] of 7-10 or of 4-6 with >or=3 Amsel criteria) were enrolled. BV was treated with 400 mg of oral metronidazole twice a day for 7 days. Participants completed a questionnaire and vaginal swabs were collected at 1, 3, 6, and 12 months; the study end point was an NS of 7-10. A total of 121 (87%) women with an NS of 7-10 and 18 (13%) with an NS of 4-6 and >or=3 Amsel criteria were enrolled; 130 (94%) returned >or=1 vaginal samples. Sixty-eight women (58% [95% confidence interval {CI}, 49%-66%]) had a recurrence of BV (NS 7-10), and 84 (69% [95% CI, 61%-77%]) had a recurrence of abnormal vaginal flora (NS 4-10) by 12 months. A past history of BV, a regular sex partner throughout the study, and female sex partners were significantly associated with recurrence of BV and abnormal vaginal flora by multivariate analysis; the use of hormonal contraception had a negative association with recurrence. Current recommended treatment is not preventing the recurrence of BV or abnormal vaginal flora in the majority of women; factors associated with recurrence support a possible role for sexual transmission in the pathogenesis of recurrent BV.
