Mannose-binding lectin gene polymorphism, vulvovaginal candidiasis, and bacterial vaginosis.

OBJECTIVE: To evaluate associations between polymorphisms in the gene coding for mannose-binding lectin (MBL) and the diagnosis of acute or recurrent vulvovaginal candidiasis and bacterial vaginosis METHODS: Women at two outpatient clinics in Brazil filled out a questionnaire and were examined for the presence of vulvovaginal candidiasis or bacterial vaginosis. A buccal swab was blindly tested for codons 54 and 57 MBL2 gene polymorphisms by polymerase chain reaction and endonuclease digestion. RESULTS: A total of 177 women were enrolled. Vulvovaginal candidiasis was identified in 78 (44.1%) women, 33 (18.6%) had bacterial vaginosis, and 66 (37.3%) were normal controls. Recurrent vulvovaginal candidiasis was present in 50 (64.1%) of the women with vulvovaginal candidiasis; 20 (60.6%) of the bacterial vaginosis patients had recurrent disease. Vulvovaginal candidiasis was associated with white race (P=.007), bacterial vaginosis was associated with nonwhite race (P=.05), and both were associated with a history of allergy (P≤.02) and having sexual intercourse at least three times a week (P<.001). Carriage of the variant MBL2 codon 54 allele B was more frequent in women with recurrent vulvovaginal candidiasis (25.0%) than in the women with acute vulvovaginal candidiasis (17.9%) or controls (10.6%) (P=.004). Allele B was also more prevalent in women with recurrent bacterial vaginosis (22.5%) than in those with acute bacterial vaginosis (0%) (P=.009). The MBL2 codon 57 polymorphism was infrequent and not associated with vulvovaginal candidiasis or bacterial vaginosis. CONCLUSION: The incidence of vulvovaginal candidiasis and bacterial vaginosis differs by ethnicity in Brazilian women. The MBL2 codon 54 gene polymorphism is associated with both recurrent vulvovaginal candidiasis and recurrent bacterial vaginosis. LEVEL OF EVIDENCE: III

The prevalence of urogenital infections in pregnant women experiencing preterm and full-term labor.

Urogenital infections are extremely prevalent during pregnancy and are an important cause of premature labor. However, the prevalence of urogenital infections during childbirth is not well known. Objective. Identify urogenital infections present at the beginning of labor in both full-term and preterm pregnancies. Study Design. Ninety-four women were admitted to the inpatient maternity clinic of the Federal University of Rio Grande do Norte (UFRN). In total, 49 women in preterm labor and 45 women in full-term labor were included in the study, and samples of urinary, vaginal, and perianal material were collected for microbiological analysis. Results. The prevalences of general infections in the preterm labor group and the full-term labor group were 49.0% and 53.3% (P = 0.8300), respectively. Urogenital infections in the preterm and full-term labor groups included urinary tract infection in 36.7% and 22.2% of women, vaginal candidiasis in 20.4% and 28.9% of women, bacterial vaginosis in 34.7% and 28.9% of women, and group B streptococcus in 6.1% and 15.6% of women, respectively. Conclusions. Urogenital infections were prevalent in women in preterm labor and full-term labor; however, significant differences between the groups were not observed.

Influência dos sintomas climatéricos sobre a função sexual de mulheres de meia-idade

PURPOSE: To evaluate the influence of climacteric symptoms on the sexual function in middle-aged women. METHODS: A cross-sectional population study was conducted on a sample of 370 middle-aged women, aged 40 to 65 years-old, cared for at the Basic Health Units in Natal, in the state of Rio Grande do Norte, Brazil. We used a questionnaire containing questions on sociodemographic, clinical, and behavioral characteristics. Sexual function was evaluated by the Female Sexual Function Index (FSFI), while the menopause symptoms by the Menopause Rating Scale (MRS). RESULTS: In the studied group, 67% of the women reported risk for sexual dysfunction (FSFI≤26.5). All FSFI domains (desire, arousal, lubrication, orgasm, satisfaction, and pain) were lower in women with risk for sexual dysfunction (p<0.001). The arousal, orgasm, and pain domains were most likely to contribute to lower FSFI scores. All somatovegetative, urogenital, and psychological MRS symptoms were more elevated in women with risk for sexual dysfunction, being significant for all comparisons (p<0.001). Logistic regression analysis revealed that the likelihood of women with risks of sexual dysfunction to present hot flushes, depression, sexual problems, and vaginal dryness was, respectively, 2.1 (95%CI 1.2–3.5); 2.4 (95%CI 1.5–4.1); 2.3 (95%CI 1.4–3.8), and 2.2 (95%CI 1.3–3.6) times higher, respectively, compared to those without any risk. CONCLUSION: Climacteric symptoms seem to influence the sexual function inPURPOSE To evaluate the influence of climacteric symptoms on the sexual function in middle-aged women.

Evaluation of hygienic douching on the vaginal microflora of female sex workers

To determine the frequency of abnormal vaginal flora and bacterial vaginosis (BV) in female sex workers (FSW) and the association between douching and vaginal microflora imbalance, a cross-sectional study enrolled 94 users and 61 non-users of vaginal douching. The social-demographic and sexual profile of these women was obtained and their abnormal vaginal flora, BV, vaginal candidiasis, trichomoniasis and cytolitic vaginosis on blinded samples were identified by Gram stain. A stepwise multivariate regression determined the risk of development of vaginal microflora imbalance. Prevalence of abnormal flora, BV, candidiasis, trichomoniasis and cytolytic vaginosis in the entire FSW was 75.5%, 51.0%, 5.1%, 0.64% and 1.9%, respectively. There were no significant differences in these findings between users and non-users of vaginal douching. Regression analysis did not identify any increased risk for altered vaginal flora or BV in vaginal douche users. In conclusion, vaginal douching did not increase the rate of these alterations in FSW.

Evaluation of Sexual Function in Brazilian Women with Recurrent Vulvovaginal Candidiasis and Localized Provoked Vulvodynia

INTRODUCTION Recurrent vulvovaginitis is an important trigger for inflammatory processes that in many cases may result in vulvovaginal pain. Vulvodynia, a vulvar disorder, can also cause a lot of pain in the female genitals. The sexual function in women with vulvodynia or recurrent vulvovaginitis will possibly be negatively affected and therefore should be evaluated. AIM To assess sexual function in women with recurrent vulvovaginal candidiasis (RVVC) and localized provoked vulvodynia (LPV) in comparison with women without lower genital tract dysfunction. METHODS A 1-year cross-sectional study evaluated sexual function in 58 women (11 with RVVC, 18 with LPV, and 29 controls) seen at a university outpatient clinic. Sexual function was assessed by taking into account the results obtained from the application of the Female Sexual Function Index (FSFI) questionnaire. Kruskal-Wallis, Mann-Whitney, chi-square, and Fishers tests were used for statistical analysis. MAIN OUTCOME MEASURE FSFI, a validated questionnaire in Portuguese. RESULTS There were no significant differences in the three groups with respect to age, marital status, schooling, race, body mass index, contraceptive method, and parity. The FSFI questionnaire total score found was 25.51 (±5.12), 21.17 (±5.15), and 29.56 (±3.87) for the RVVC, LPV, and control groups, respectively. The scores were significantly statistically lower in the study groups compared with the control group (P<0.05). Women with RVVC and LPV also had lower total scores compared with 26.55 values, considered a cutoff score for sexual dysfunction in literature. The LPV group showed a significant difference and scored worse in the domains of arousal, lubrication, orgasm, satisfaction, and pain but not in the domain of sexual desire. The same occurred with the RVVC group but only for the domains of orgasm and satisfaction. CONCLUSION Women with RVVC and LPV had significantly more symptoms of sexual dysfunction than women without lower genital tract diseases.

Influência da freqüência de coitos vaginais e da prática de duchas higiênicas sobre o equilíbrio da microbiota vaginal

PURPOSE: to verify if the high frequency of vaginal intercourses and the use of doushing interferes with vaginal microbiota. METHODS: ninety-seven women were examined at a health center located in the prostitution area of the city of Campinas, and evaluated in a prospective cross-sectional study. Anamnesis determined the frequency of vaginal intercourse and the use of douching in the 44 sex professionals and 53 non-professionals studied. The vaginal content was collected with a sterile Dacron swab, from the right vaginal wall, and placed on to two glass laminas. The vaginal microbiota smear stained by the Gram technique was studied with light microcopy using immersion lens and the data were analyzed. The sex professionals and non-professionals presented mean age of 24.9±6.4 and 31.5±9.7, habit of smoking in 52.2 and 24.5%, the use of vaginal lubricants in 56.8 and 0%, and the use of condoms in 100 and 41.5% of the cases, respectively. RESULTS: only 1.8% of the women in the control group had seven or more sexual intercourses per week, contrasting evidently with the sex professionals (97.7%). There were no significant differences regarding race, educational level and number of pregnancies. Bacterial vaginosis and abnormal vaginal flora were more observed in sex professionals (p=0.02 and 0.001) and were associated with the high frequency (seven times or more) of weekly vaginal intercourses (p=0.04 and 0.001). Cytolytic vaginosis was more related to non-professionals (p=0.04) and to a lower frequency of sexual intercourses (p=0.04). The use of doushing was more common in the sex professionals (p=0.002). However, this practice was not associated either with the vaginal microbiota problems or with the presence of vulvovaginitis. CONCLUSIONS: sex professionals with seven or more sexual intercourses per week presented a higher frequency of bacterial vaginosis and abnormal vaginal flora. The doushing habit did not interfere with the vaginal environment ecosystem of the studied women.

Genital ulcers in women: clinical, microbiologic and histopathologic characteristics.

Female genital ulcer is a disease that affects a large number of women, and its etiologic diagnosis can be difficult. The disease may increase the risk of acquiring HIV. Genital ulcer may be present in sexually transmitted diseases (STD)--syphilis, chancroid, genital herpes, donovanosis, lymphogranuloma venereum; and other non-STD disorders (NSTD)--Behçets syndrome, pemphigus, Crohns disease, erosive lichen planus and others. This study evaluated the clinical-histopathologic-microbiologic characteristics of female genital ulcers. A cross-sectional descriptive prospective study was conducted during a six-month period to investigate the first 53 women without a definitive diagnosis, seeking medical care for genital ulcers at a genital infections outpatient facility in a university hospital. A detailed and specific history was taken, followed by a dermatologic and gynecologic examination. In addition to collecting material from the lesions for microbiologic study, a biopsy of the ulcer was performed for histopathologic investigation. The average age of the patients was 32.7 years, 56.6% had junior high school education and higher education. The most frequent etiology was herpetic lesion, followed by auto-immune ulcers. At the time of their first consultation, around 60% of the women were using inadequate medication that was inconsistent with the final diagnosis. Histologic diagnosis was conclusive in only 26.4% of the patients (14/53). Cure was obtained in 99% of the cases after proper therapy. The female genital ulcers studied were equally distributed between sexually transmitted and non-sexually transmitted causes. Herpes was the most frequent type of genital ulcer, affecting women indiscriminately, mostly between the ages of 20 and 40 years. The etiologic diagnosis of herpetic ulcers is difficult to make even when various diagnostic methods are applied. It is imperative that NSTD should be included in the differential diagnoses of female genital ulcers. The histopathologic exam is not a diagnostic tool in the majority of cases and should not be considered the gold standard test, being of little value in cases of NSTD and STD ulcers.

The effect of "breathable" panty liners on the female lower genital tract.

To evaluate whether the use of “breathable” panty liners (BPLs) alters the normal vaginal flora, increases the incidence of bacterial vaginosis and/or vaginal candidiasis, or causes vulvar irritation.

Altered CD16 expression on vaginal neutrophils from women with vaginitis.

OBJECTIVE Reduced CD16 expression is associated with neutrophil apoptosis. This study aimed to compare CD16 expression on neutrophils in the vagina from women with normal bacterial flora and with vaginitis. STUDY DESIGN Vaginal lavages were sampled from volunteers diagnosed with bacterial vaginosis (BV, n=34), vulvovaginal candidiasis (VC, n=43), BV plus VC (BV+VC, n=14), and normal flora (NF, n=51). Neutrophils were identified by expression of CD15, CD16 and CD24 surface markers as assessed by flow cytometry. RESULTS CD16 expression was elevated in neutrophils from women with vaginitis (BV p<0.0001; VC p=0.01; BV+VC p=0.0027) as compared to women with NF. CONCLUSION The reduction in CD16 down-regulation is consistent with prolonged neutrophil viability and activity in the vagina of women with vaginitis. This may contribute to greater microbial clearance and, conversely, with inflammation-associated pathology.
