The aim of this study was to identify Candida species isolated from women diagnosed with recurrent vulvovaginal candidiasis (RVVC) and their partners; and to evaluate the fluconazole (FLZ) susceptibility of the isolates. In a period of six years, among 172 patients diagnosed with vulvovaginal candidiasis, 13 women that presented RVVC and their partners were selected for this investigation. The isolates were obtained using Chromagar Candida medium, the species identification was performed by phenotypic and molecular methods and FLZ susceptibility was evaluated by E-test. Among 26 strains we identified 14 Candida albicans, six Candida duobushaemulonii, four Candida glabrata, and two Candida tropicalis. Agreement of the isolated species occurred in 100% of the couples. FLZ low susceptibility was observed for all isolates of C. duobushaemulonii (minimal inhibitory concentration values from 8-> 64 µg/mL), two C. glabrata isolates were FLZ-resistant and all C. albicans and C. tropicalis isolates were FLZ-susceptible. This report emphasises the importance of accurate identification of the fungal agents by a reliable molecular technique in RVVC episodes besides the lower antifungal susceptibility profile of this rare pathogen C. duobushaemulonii to FLZ.

OBJETIVO: Identificar as espécies predominantes e o papel dos parceiros sexuais na manutenção das vulvovaginites recorrentes por Candida spp. MÉTODOS: Entre agosto de 2007 e março de 2012, foi efetuado estudo prospectivo de 830 pacientes com idades variáveis entre 18 e 65 anos e vaginites fúngicas. Foram excluídos pacientes com diabetes mellitus, síndrome da imunodeficiência adquirida (AIDS), em uso de corticoterapia, antibioticoterapia, hormonoterapia, imunossupressão, duchas vaginais, dispositivos intrauterinos (DIUs) ou espermicidas. A identificação das espécies de Candida foi feita por métodos fenotípicos e genotípicos. O teste do χ2 foi usado para correlacionar a Candida spp. nos parceiros masculinos e a recorrência nas vaginites. RESULTADOS: O agente fúngico foi isolado em um total de 40 mulheres, sendo 24 com vaginites recorrentes, e em 15 dos seus parceiros sexuais, dos quais 10 eram assintomáticos, e 5, sintomáticos. Houve concordância das espécies encontradas no casal em 100% das recorrências. C. albicans (62,4 e 60%), C. glabrata (29,1 e 33,3%) e C. guilliermondii foram as espécies identificadas. Candida tropicalis (4,1%) foi isolada de apenas uma paciente. Nas 16 mulheres restantes que tinham vaginites não complicadas, C. albicans foi isolada em todas. C. glabrata foi isolada em apenas dois de seus parceiros assintomáticos. CONCLUSÃO: Houve predominância de C. albicans; parceiros sintomáticos ou assintomáticos podem ter papel importante como reservatório e fonte de transmissão de leveduras, principalmente nos quadros de vulvovaginites recorrentes.

PURPOSE: To identify the predominant species and the role of sexual partners in the maintenance of recurrent vulvovaginitis by Candida spp. METHODS: A prospective study of 830 patients aged 18 to 65 years with yeast vaginitis was performed between August 2007 and March 2012. Patients with diabetes mellitus, AIDS or taking corticosteroids, antibiotics or hormone therapy and immunosuppressed patients, patients using vaginal douches, spermicides or intrauterine devices were excluded from the study. Candida species were identified by phenotypic and genotypic methods. The chi-square test was used to correlate the presence of Candida spp. in male partners with the recurrence of vaginitis. RESULTS: The fungal agent was isolated from a total of 40 women, 24 with recurrent vaginitis and from 15 of their sexual partners, 10 of whom were asymptomatic while 5 were symptomatic. There was agreement of the species found in the couple in 100% of recurrences. C. albicans (62.4 and 60%), C. glabrata (29.1 and 33.3%) and C. guilliermondii species were identified. Candida tropicalis (4.1%) was isolated from only one patient. Candida albicans was isolated from the remaining 16 women who had uncomplicated vaginitis. C. glabrata was isolated from only two of the asymptomatic partners. CONCLUSION: There was a predominance of C. albicans and symptomatic or asymptomatic partners can play an important role as a reservoir and source of transmission of yeast, especially in cases of recurrent vulvovaginitis.

OBJETIVO: relacionar as leveduras identificadas aos sinais e sintomas clínicos das pacientes com candidíase vulvovaginal e investigar a importância dos parceiros sexuais na reincidência da infecção. MÉTODOS: foi desenvolvido estudo prospectivo de julho de 2001 a julho de 2003 com uma amostra de mulheres residentes na Grande São Paulo. Foram avaliadas 179 pacientes com suspeita clínica de vaginite fúngica, com idade entre 18 e 65 anos. Os critérios para exclusão foram: gravidez, comprometimento imunológico intrínseco e extrínseco, incluindo AIDS, diabetes, imunossupressão, pacientes em terapia com corticosteróides, antibióticos ou hormônios, em pós-menopausa, em uso de dispositivo intra-uterino e duchas vaginais ou espermicidas. Amostras de secreções vaginais ou da glande dos parceiros sexuais de pacientes com vaginite de repetição foram coletadas para microscopia e cultura de fungos. Colônias fúngicas isoladas em CHROMagar Candida foram identificadas por provas clássicas. O teste exato de Fisher foi usado para correlacionar o quadro clínico com as leveduras isoladas das pacientes. RESULTADOS: os sinais e sintomas clínicos mais relevantes na candidíase vulvovaginal foram prurido e corrimento, seguidos por eritema e edema, estatisticamente independente do agente etiológico. Leveduras foram diagnosticadas por microscopia direta em 77 pacientes com vulvovaginites, sendo obtidos 40 cultivos de Candida spp. Candida albicans (70%), C. glabrata (20%), C. tropicalis (7,5%) e C. guilliermondii (2,5%) foram identificadas. As leveduras prevalentes nos parceiros foram C. albicans e C. glabrata. As mesmas espécies foram detectadas nas companheiras e parceiros em 87% dos casos. CONCLUSÕES: as vulvovaginites fúngicas foram mais freqüentes em mulheres entre 18 e 34 anos de idade. Não foi observada correlação entre as espécies de leveduras detectadas e a sintomatologia clínica. Os parceiros sexuais podem ser importantes reservatórios de Candida spp e estar relacionados à manutenção da candidíase vulvovaginal.

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.
