Objectives: The objective of this study was to investigate the presence of oral lesions in human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients in a descriptive cross-sectional study, and to establish their presence according to levels of CD4+ cells (including the CD4+/CD8+ cell ratio). Materials and Methods: A total of 75 patients infected with HIV were included. Oral lesions were observed and classified using World Health Organization classification guidelines...

ETHNOPHARMACOLOGICAL RELEVANCE: The stem bark of Stryphnodendron adstringens (Mart.) Coville is popularly used as anti-inflammatory, astringent and in the treatment of wounds and vaginal infections. Several pharmacological activities have been scientifically proven by "in vitro" and "in vivo" experimental assays for antibacterial, antiviral, antiprotozoan, anti-inflammatory and antioxidant. AIM OF THE STUDY: We investigated whether proanthocyanidin polymeric tannins from the Stryphnodendron adstringens steam bark with antifungal activity against Candida albicans in vitro are also active against planktonic and biofilm cells of Candida non-albicans (CNA, including fluconazole-resistant isolates) and are capable of controlling Candida vaginitis in vivo...

Oral keratinocytes provide the first line of host defense against oral candidiasis. We speculated that interactions of fungal cell wall components with oral keratinocytes regulate stress response against Candida infection, and examined the expression of genes induced by heat-killed Candida albicans in oral immortalized keratinocytes using a cDNA microarray technique. Of 24,000 genes revealed by that analysis, we focused on HO-1, a stress-inducible gene, as its expression was increased by both heat-killed as well as live C...

Invasive candidiasis (IC) is a major cause of morbidity and mortality despite antifungal treatment. Azoles and echinocandins are used as first-line therapies in IC. However, their efficacy is limited by yeast tolerance and the emergence of acquired resistance. Tolerance is a reversible stage due to the yeast's capacity to counter the antifungal drug exposure, leading to persistent growth. In C. albicans, multiple stress signaling pathways have been shown to contribute to this adaptation. Among those, the Rim pH-responsive pathway, through its transcription factor Rim101p, was shown to mediate azole and echinocandin tolerance...

Candida glabrata, the second most frequent cause of candidiasis after Candida albicans, is an emerging human fungal pathogen that is intrinsically drug tolerant. Currently, studies of C. glabrata genes involved in drug tolerance are limited. Ada2, a component serving as a transcription adaptor of the Spt-Ada-Gcn5 acetyltransferase (SAGA) complex, is required for antifungal drug tolerance and virulence in C. albicans However, its roles in C. glabrata remain elusive. In this study, we found that ada2 mutants demonstrated severe growth defects at 40°C but only mild defects at 37°C or 25°C...

BACKGROUND: Opportunistic infections due to Candida species occur frequently in cancer patients because of their inherent immunosuppression. The aim of the present study was to investigate the epidemiology of yeast species from the oral cavity of patients during treatment for oncological and haematological malignancies. METHODS: MALDI-TOF was performed to identify yeasts isolated from the oral cavity of 350 cancer patients. Moreover, antifungal susceptibility testing was performed in according to CLSI guidelines (M27-A3)...

Background: Short-term medical missions (STMMs) have increased and are viewed as a way to extend care in low- and middle-income countries (LMICs). Although benefits may exist, visiting teams may lack insight into using medications safely and effectively. The primary objective was to assess prescribing differences between US-based and Dominican Republic (DR) healthcare providers on STMMs in the DR. Methods: A retrospective database review between January 2013 and 2015 was conducted...

Invasive fungal infections (IFIs) are a major threat to patients undergoing solid organ transplantation (SOT). Owing to improvements in surgical techniques, immunosuppression therapy and antifungal prophylaxis, the incidence of IFIs has been decreasing in recent years. However, IFI-associated morbidity and mortality remain significant. Invasive candidiasis (IC) and aspergillosis (IA) are the main IFIs after SOT. Risk factors for IC and IA continue to evolve, and thus strategies for their prevention should be constantly updated and targeted to both individual patient risk factors and local epidemiology...

In the past, most antifungal therapy dosing recommendations for invasive candidiasis followed a 'one-size fits all' approach with recommendations for lowering maintenance dosages for some antifungals in the setting of renal or hepatic impairment. A growing body of pharmacokinetic/pharmacodynamic research, however now points to a widespread 'silent epidemic' of antifungal underdosing for invasive candidiasis, especially among critically ill patients or special populations who have altered volume of distribution, protein binding and drug clearance...

The treatment of invasive candidiasis has changed greatly in the past decade and must continue to evolve if we are to improve outcomes in this serious infection. A review of recent history may provide insights for the future. The morbidity and mortality of invasive candidiasis remain difficult to measure despite an obvious clinical burden. Current treatment guidelines now recommend echinocandins as first-line empirical treatment, with fluconazole as an acceptable alternative for selected patients, reflecting the efficacy demonstrated by echinocandins and increasing resistance observed with fluconazole...

The epidemiology of invasive candidiasis has evolved in recent years, warranting a review of the changes and the implications for current and future diagnosis and treatment. The overall burden of invasive candidiasis remains high, particularly in the expanding populations of patients at risk of opportunistic infection, such as the elderly or immunosuppressed. Progressive shifts from Candida albicans to non-albicans Candida spp. have been observed globally. The recent emergence of novel, multiresistant species, such as Candida auris, amplifies the call for vigilance in detection and advances in treatment...

PURPOSE: To report 2 cases with late postoperative Candida albicans interface keratitis and endophthalmitis after Descemet stripping automated endothelial keratoplasty (DSAEK) with corneal grafts originating from a single donor with a history of presumed pulmonary candidiasis. METHODS: Two patients underwent uncomplicated DSAEK by 2 corneal surgeons at different surgery centers but with tissue from the same donor and were referred to the Bascom Palmer Eye Institute with multifocal infiltrates at the graft-host cornea interface 6 to 8 weeks later, and anterior chamber cultures that were positive for the same genetic strain of C...

AIMS: Guidelines on treating invasive candidiasis recommend initial treatment with a broad-spectrum echinocandin (e.g., micafungin); then switching to fluconazole if isolates prove sensitive (de-escalation strategy). This study aimed to evaluate the cost-effectiveness of de-escalation from micafungin versus escalation from fluconazole from a Chinese public payers perspective. MATERIALS AND METHODS: Cost-effectiveness was estimated using a decision analytic model, in which patients begin treatment with fluconazole 400 mg/day (escalation) or micafungin 100 mg/day (de-escalation)...

Background and Purpose: Treatment of life-threatening fungal infections caused by Candida species has become a major problem. Candida spp. are the most important causative agents of candidiasis. Allium tripedale is a medicinal plant that has been traditionally used to treat infections. In the present study, we aimed to determine the chemical compounds and antimicrobial activity of hydroalcoholic extract of A. tripedale against different species of Candida. Materials and Methods: Phytochemical analysis was performed to identify the possible bioactive components of this extract by using gas chromatography and mass spectroscopy (GC-MS)...
