Effect of butyl alcohol extract of Baitouweng Decoction on vaginal mucosal neutrophil chemotaxis in vulvovaginal candidiasis mice / 中国中药杂志

To investigate the effects of butyl alcohol extract of Baitouweng Decoction(BAEB) on neutrophil chemotaxis in vaginal mucosa of mice with vulvovaginal candidiasis(VVC). Seventy-two SPF female Kunming mice were randomly divided into normal control group, model group, fluconazole group, BAEB low-dose group, middle-dose group and high-dose group. Subcutaneous injection of estradiol benzoate was conducted to induce pseudo-estrus, and then 2×10~6 CFU·mL~(-1)of Candida albicans was inoculated into vaginal lumen, followed by drug treatment for 7 days. Gram staining was used to observe the morphological changes of C. albicans in vagina; vaginal fungal load was detected on agar plate. Histological changes of vaginal tissues in mice were observed by HE staining. Lactate dehydrogenase(LDH), interleukin-6(IL-6) and tumor necrosis factor(TNF-α) levels in mouse lavage fluid were detected by enzyme-linked immunosorbent assay(ELISA). Neutrophils in vaginal lavage fluid was observed and counted by using Pap smear. The levels of IL-8 and MIP-2 in vaginal mucosa were detected by ELISA. IL-8 and MIP-2 mRNA levels in vaginal mucosa of mice were detected by qRT-PCR. The results showed that as compared with the normal group, VVC model group had a large number of hyphae and a high level of fungal loadinvagina. The vaginal mucosa was completely destroyed, the number of neutrophils increased, and the protein and mRNA levels of IL-8 and MIP-2 were up-regulated. After BAEB treatment, the hyphae of the treatment group was decreased, the fungal load was decreased, the impaired mucosa showed different degrees of improvement, the inflammatory factors were decreased to varying degrees, and the protein and mRNA levels of chemokine IL-8 and MIP-2 were down-regulated. In conclusion, BAEB may be used to treat VVC by inhibiting vulvovaginal candidiasis via blocking neutrophils recruitment into vagina.

Prevalence of vulvovaginal candidiasis in females in the reproductive age group

Background: Vulvovaginal candidiasis (VVC) is a common infection among reproductive age group females. The objective of present study is to determine the prevalence of vulvovaginal candidiasis, its distribution and association of risk factors among reproductive age group females, attending the outpatient department of obstetrics and gynaecology of our Prime Medical Centre, Sharjah attached with Prime Hospital, Dubai, United Arab Emirates (UAE).Methods: It was cross-sectional descriptive study over a period of six months. Patients who came to our outpatient department with complains of vaginal discharge and itching in reproductive age group were included in this study. Patients characteristics i.e. age, parity, risk factors like diabetes, pregnancy, use of oral contraceptive pills (OCPills) and intrauterine contraceptive device (IUCD) were noted. High vaginal swabs (HVS) were collected and sent for culture. Candida positive cases were noted, and results were analyzed.Results: A total of 224 high vaginal swabs were collected. Prevalence of vulvovaginal candidiasis was found to be 31.6%. It was found more in 26-30 years age group and multiparous women. Previous history of candidiasis and diabetes were the commonest risk factors. Frequency of C. albicans was more (76.05%) than non-albicans candida (23.94%).Conclusions: Present study concluded that vulvovaginal candidiasis is more prevalent in reproductive age group females, therefore a routine high vaginal swab culture must be performed in every woman presenting with vaginal discharge and itching for correct diagnosis. Women should be educated on clinical symptoms.
