Pulmonary valve infections without the involvement of other valves account for only 1.5- 2% of all infective endocarditis cases. Isolated pulmonary valve endocarditis due to fungus is extremely rare. The case is presented of a 36-year-old male who was found to have isolated pulmonary valve endocarditis caused by a very rare organism, Candida parapsilosis, and that was solely managed with medical therapy. The patient was evaluated for three weeks of lowgrade fever, generalized rash and fatigue, and found to have C...

The in vitro anti-fungal activity of aspirin against cryptococcal cells has been reported. However, its undesired effects may limit its clinical application. Conceivably, a derivative of aspirin could overcome this challenge. Toward this end, this paper considered the usage of an aspirinate-metal complex viz. copper acyl salicylate (CAS) as an anti- Cryptococcus anti-fungal agent. Additionally, the paper examined the influence of this compound on macrophage function. The in vitro susceptibility results revealed that cryptococcal cells were vulnerable (in a dose-dependent manner) to CAS, which may have effected growth inhibition by damaging cryptococcal cell membranes...

Natural Killer (NK) cells are involved in the host immune response against infections due to viral, bacterial and fungal pathogens, all of which are a significant cause of morbidity and mortality in immunocompromised patients. Since the recovery of the immune system has a major impact on the outcome of an infectious complication, there is major interest in strengthening the host response in immunocompromised patients, either by using cytokines or growth factors or by adoptive cellular therapies transfusing immune cells such as granulocytes or pathogen-specific T-cells...

Candidemia is a bloodstream fungal infection caused by Candida species and is most commonly observed in hospitalized patients. Even with proper antifungal drug treatment, mortality rates remain high at 40-50%. Therefore, prophylactic or preemptive antifungal medications are currently recommended in order to prevent infections in high-risk patients. Moreover, the majority of women experience at least one episode of vulvovaginal candidiasis (VVC) throughout their lifetime and many of them suffer from recurrent VVC (RVVC) with frequent relapses for the rest of their lives...

β-glucan, the most abundant fungal cell wall polysaccharide, has gained much attention from the scientific community in the last few decades for its fascinating but not yet fully understood immunobiology. Study of this molecule has been motivated by its importance as a pathogen-associated molecular pattern upon fungal infection as well as by its promising clinical utility as biological response modifier for the treatment of cancer and infectious diseases. Its immune effect is attributed to the ability to bind to different receptors expressed on the cell surface of phagocytic and cytotoxic innate immune cells, including monocytes, macrophages, neutrophils, and natural killer cells...

BACKGROUND: Infection is still a leading cause of death during the first year after lung transplantation. We performed a multicenter study among teaching hospitals to assess monitoring of early humoral immunity as a means of identifying lung recipients at risk of serious infections. METHODS: We prospectively analyzed 82 adult lung recipients at 5 centers in Spain. Data were collected before transplantation and at 7 and 30 days after transplantation. Biomarkers included IgG, IgM, IgA, complement factors C3 and C4, titers of antibodies to pneumococcal polysaccharide antigens (IgG, IgA, IgM) and antibodies to cytomegalovirus (IgG), and serum B-cell activating factor (BAFF) levels...

Spores and fungal fragments found in indoor and outdoor environments originate from opportunistic fungi and they can contribute to inflammatory responses, causing a broad range of symptoms. Papers were selected and reviewed with an emphasis on the molecular mechanisms involved in the effect of fungi on immune cells, especially mast cells (MCs). Fungi can bind to antibodies and complement them, allowing them to be recognized by cells of the innate immune system, including macrophages, dendritic cells, and MCs, which are then stimulated via Toll-like receptor signaling...

Systemic bacterial infections are prone to secondary Candida albicans superinfection. However, the molecular mechanisms involved remain poorly understood. In this study, a model comprising sub-lethal cecal ligation and puncture (CLP) plus C. albicans intravenous injection (i.v.) was applied to mimic the situation in superinfection. Compared with mice without systemic bacterial infection, mice with systemic bacterial infection had lower anti-fungal gene expression (including Il1b, Tnf, Il6, Ifnb, Ifng, Cxcl1, and Ccr2) in monocytes, and less inflammatory monocytes and neutrophils infiltrating into the kidney when challenged with C...

To further enhance the anti-Aspergillus efficacy of our previously discovered antifungal lead compound 1, a series of benzoheterocycle analogues were designed, synthesized and evaluated for their in vitro antifungal activity. The most promising compounds 13s and 14a exhibited excellent antifungal activity against C. albicans, C. neoformans, A. fumigatus and fluconazole-resistant C. albicans strains, that was superior or comparable to those of the reference drugs fluconazole and voriconazole. GC-MS analyses suggested that the novel compound 13s might have a similar mechanism to fluconazole by inhibiting fungal lanosterol 14α-demethylase (CYP51)...
