PURPOSE: To quantify the number of defense cells and immunoglobulin E (IgE) levels in peripheral blood sampled from women with recurrent vulvovaginal candidiasis. METHODS: A cross-sectional study was conducted on 60 women, 40 with vulvovaginal candidiasis and 20 controls. The defense cells were identified using an impedance system combined with flow cytometry and total and specific IgE was measured by chemiluminescence. The Mann-Whitney test was used for nominal variables and the Spearman test was used to determine the correlation of IgE concentration and eosinophils in peripheral blood. RESULTS: The number of eosinophils in peripheral blood from patients with recurrent vulvovaginal candidiasis, 302.60 (±253.07), was significantly higher compared to control, 175.75 (±109.24) (p=0.037). Serum levels of total and specific IgE were similar in the groups of women with and without recurrent vulvovaginal candidiasis (p=0.361). However, there was a moderate positive correlation between eosinophils and total serum IgE in the candidiasis group (r=0.25). CONCLUSION: Women with recurrent vulvovaginal candidiasis are more likely to have eosinophils in peripheral blood.

PURPOSE: to study vulvovaginal candidiasis from the vaginal fluid of women with and without clinical suspicion, identifying the frequency of Candida spp., and associating it with intrinsic and extrinsic risk factors. METHODS: a total of 286 samples from patients attended in private practices and public health units from August 2005 to August 2007 were collected, being 121 women under clinical suspicion and 165, without. The samples were collected with sterile swabs, taken to the laboratory in 0.85% physiological solution, and then seeded in CHROMagar Candida and in 4% agar Sabourad with chloramphenicol. Classical identification procedures were carried out: macro and micromorphology, zymogram and auxanogram. Data obtained were analyzed by frequency tests and contingency tables (χ2). RESULTS: a total of 47.9% of the women under clinical suspicion got confirmation of candidiasis by the laboratorial tests. Among the patients without clinical suspicion (Control Group), 78.2% were vulvovaginal candidiasis negative according to the laboratorial tests. Candida albicans was the prevalent strain in 74.5% of the cases. There were significant differences among the positive cases, according to the patients from the two cities evaluated (p<0.05). Clothing was one differential aspect found among the two populations studied. CONCLUSIONS: the presence of predisposing factors does not necessarily define vulvovaginal candidiasis. Geographical localization has shown to be a relevant factor in the distribution of events. The type of clothing may be one of the reasons for it. Culture of samples from the vaginal contents, followed by microorganisms' identification, can be important.

PURPOSE: to characterize, phenotypically, yeasts isolated from the vaginal content of 223 symptomatic (S) and asymptomatic (A) adult women with vulvovaginitis, and to determine the clinical indicators which may lead to the appearance of signs and symptoms related to the mucosa involvement by this pathology. METHODS: a questionnaire with open and closed questions on epidemiological clinical data was applied initially. Then, mycological diagnosis with sowing in Chrom Agar Candida was done, followed by micro-morphological and biochemical identification. Specific methods for the detection of the virulence factors, proteinase and phospholipase were employed. Statistical analysis was performed through χ2 and Pearson's χ2 tests. RESULTS: the most prevalent species found was Candida albicans (87%, S and 67%, A) followed by Candida glabrata (4%, S e 17% A). The number of women reporting the use of contraceptives was higher among the symptomatic, 77%. In the two groups studied, about 87% of the women presented regular menstrual cycles and 57% were married with ages between 30 to 40 years old. Concerning the sexual practices, there has been concomitance among anal, oral and vaginal habits from the patients. Only Candida albicans produced the virulence factor phospholipase in 37.5% of them. Proteinase has been detected in Candida albicans, Candida glabrata and Candida parapsilosis. This latter virulence factor was mainly associated to isolates from symptomatic patients. CONCLUSIONS: it is a fact that the vaginal mucosa can be colonized and infected by yeasts, with several Candida species present. Nevertheless, Candida albicans is the most prevalent in the vaginal mucosa of adult women. It is evident the emergence of non-albicans Candida species, some of them with intrinsic resistance to azolics, such as Candida glabrata, Candida parapsilosis, Candida tropicalis, and Candida guillermondii, which can be explained by the inadequate use of medicines and empirical treatment.

PURPOSE: to relate yeasts identified by laboratory tests to clinical signs and symptoms in patients with vulvovaginal candidiasis, and to investigate the importance of the sexual partners in the recurrence of the infection. METHODS: from July 2001 to July 2003, a sample of 179 patients aged from 18 to 65 years old, with clinical suspicion of fungal vaginitis were analyzed in a prospective study in Great São Paulo. Exclusion criteria included: pregnancy, impaired intrinsic or extrinsic immune response (including Aids), diabetes or immunosuppression; patients undergoing corticosteroid, antibiotic or hormone therapy, in post menopause, with intrauterine device (IUD) or making use of vaginal douches or spemicides. Samples of vaginal and penis secretions from partners of patients with relapse of vaginitis episodes were collected for microscopy and fungal culture. Fungal colonies isolated in CHROMagar Candida were identified by classical methods. Fisher's exact t-test was used to correlate the clinical picture with the yeasts isolated from patients. RESULTS: the most relevant clinical signs and symptoms were pruritus and vaginal discharge followed by erythema and edema, statistically independent from the etiological agent. Direct microscopy revealed yeasts in 77 patients with vulvovaginitis, and 40 Candida spp cultures were obtained. Candida albicans (70%), C. glabrata (20%), C. tropicalis (7,5%) and C. guilliermondii (2,5%) were identified. The yeasts prevalent in partners were C. albicans and C. glabrata. The same species were detected in female and male sex partners in 87% of the cases. CONCLUSIONS: fungal vulvovaginitis was more frequent in women between 18 and 34 years old. No correlation was observed between the species of yeast detected and clinical symptomatology. Sexual partners are important Candida spp reservoirs and may be related to the maintenance of the vulvovaginal candidiasis.

PURPOSE: to analyze patients with vulvovaginal candidiasis with respect to risk factors, symptomatology and results of anal culture, to identify the frequency of species of Candida albicans and non-C. albicans, and to correlate anal and vaginal colonization. METHODS: a total of 99 patients were included with suspected vulvovaginal candidiasis, from Natal, Brazil, between May 2003 and May 2005, totalling 294 collections. The clinical material, obtained by vaginal and anal swabs, was seeded on CHROMagar Candida®. The yeasts were identified using the classic method, in addition to the growth test at 42º and 45ºC and the Hypertonic Saboraud broth test. Symptomatology, risk factors and anal colonization were assessed according to positive or negative culture for Candida spp. The cultures positive for C. albicans at the two sites were compared with other results encountered. Yates’ chi2 test and Fisher’s exact test were used for statistical analysis. RESULTS: the most frequent was C. albicans in 69% of the cases. Wearing tight and/or synthetic underclothing, the presence of allergic diseases, the occurrence of itching, leukorrhea and hyperemia showed a significant association with positive culture for Candida spp in the vagina. The chance of a patient with positive anal colonization to present with concomitant positive vaginal colonization was 2.8 and 4.9 times greater for Candida spp and C. albicans, respectively. The risk of a patient with anal culture positive for C. albicans to present with positive vaginal colonization was 3.7 times greater when compared to non-C. albicans species. CONCLUSIONS: the most common species was C. albicans, and a relevant association between vaginal cultures positive for Candida spp and the use of tight and/or synthetic underclothing, allergic diseases, the occurrence of pruritus, leukorrhea and erythema was observed (p<0.05). Positive anal colonization concomitant with vaginal colonization was significant, suggesting possible vaginal contamination from the anus.
