Vulvovaginal candidiasis is a common mucosal infection affecting a large proportion of women with some of them affected by recurrent often intractable forms of the disease. Thus, there is an increasing interest in understanding the pathogenesis of this disease. The aim of our work was to characterize, in animal models of vaginal candidiasis, the components of the host-fungus interaction at the mucosal level.The evidence of an immune response in the vaginal compartment was very encouraging to identify the proper targets for new strategies for vaccination or immunotherapy of vaginal candidiasis...

Background: Vulvodynia is an idiopathic vulvovaginal pain condition that has significant sexual and relational consequences. Most women with vulvodynia continue to have intercourse, possibly because of a desire to approach positive outcomes (e.g., intimacy) and avoid negative outcomes (e.g., partner disappointment). Purpose: This study examined daily associations between approach and avoidance sexual goals and women's pain during intercourse and couples' sexual and relational well-being, as well as the mediating role of sexual cues...

BACKGROUND: Lanosterol demethylase (CYP51), is an enzyme essential for fungal growth, and catalyzes an early step in the biosynthetic pathway of ergosterol, a sterol required for fungal cell membrane formation and integrity. CYP51 is the molecular target of the class of drugs referred to as 'azole antifungals.' VT-1161 is a novel, oral, selective inhibitor of fungal CYP51, and is being developed for the treatment of recurrent vulvovaginal candidiasis. OBJECTIVE: We evaluated the efficacy and safety of 4 dosing regimens of oral VT-1161 compared to placebo in women with recurrent vulvovaginal candidiasis, defined as at least 3 symptomatic episodes of acute vulvovaginal candidiasis within a 12-month period...

Streptococcus agalactiae and Candida albicans often co-colonize the female genital tract, and under certain conditions induce mucosal inflammation. The role of the interaction between the two organisms in candidal vaginitis is not known. In this study, we found that co-infection with S. agalactiae significantly attenuated the hyphal development of C. albicans , and that EFG1 -Hwp1 signal pathway of C. albicans was involved in this process. In a mouse model of vulvovaginal candidiasis (VVC), the fungal burden and the levels of pro-inflammatory cytokines, IL-1β, IL-6 and TNF-α showed a increase on co-infection with S...

BACKGROUND: Spontaneous abortions are the most common complication of pregnancy. Clotrimazole and miconazole are widely used vaginal-anti-mycotic agents used for the treatment of vulvovaginal candidiasis. A previous study has suggested an increased risk of miscarriage associated with these azoles, which may lead health professionals to refrain from their use even if clinically indicated. The aim of the current study was to assess the risk for spontaneous abortions following first trimester exposure to vaginal-anti-mycotics...

Amphotericin B (AmB) is one of the most used drugs for the treatment of systemic fungal infections; however, the treatment causes several toxic manifestations, including nephrotoxicity and hemolytic anemia. Chitosan-coated poly(lactide-co-glycolide) (PLGA) nanoparticles containing AmB were developed with the aim to decrease AmB toxicity and propose the oral route for AmB delivery. In this work, the antifungal efficacy of chitosan-coated PLGA nanoparticles containing AmB was evaluated in 20 strains of fungus isolates from patients with vulvovaginal candidiasis (01 Candida glabrata and 03 Candida albicans), bloodstream infections (04 C...

Candida bracarensis is an emerging cryptic species within the Candida glabrata clade. To date, little is known about its epidemiology, virulence, and antifungal susceptibility. This study documents the occurrence of C. bracarensis for the first time in Mexico and focuses on its in vitro production of hydrolytic enzymes, as well as antifungal susceptibility to echinocandins. This strain was isolated from a vaginal swab of a female with vulvovaginal candidosis; exhibited a very strong activity of aspartyl proteinase, phospholipase, and hemolysin; and was susceptible to caspofungin, anidulafungin, and micafungin (MIC = 0...

The management of puerperal hematomas after normal delivery has always been challenging for obstetricians. Vulvar, vulvovaginal, or paravaginal hematomas are common. On the other hand, retroperitoneal hematomas are uncommon and can be life-threatening. The diagnosis of vascular injury is rarely made preoperatively as atonic or traumatic postpartum hemorrhage (PPH), uterine rupture and amniotic fluid embolism are more common differential diagnoses. Injury to internal pudendal and uterine vessels is extremely rare in cases of vaginal delivery and, therefore, the literature on this topic is very scarce...

The female genital system infections have high-incidence among various gynecological diseases. The role of endogenous peptides in female reproductive tract secretion has been rarely investigated regarding gynecological infections. To identify gynecological infections associated endogenous peptides, a comparative peptidomic profiling of vaginal secretion from sexually mature and perimenopause women was conducted in this study using nanoflow liquid chromatography-tandem mass spectrometer. A total of 3096 peptide fragments originating from 1364 precursor proteins were identified, 102 of which were discrepantly expressed, which included 60 over-expressed peptides and 42 under-expressed peptides in the sexually mature group compared with the perimenopause group...
