Role of Vaginal Mucosa, Host Immunity and Microbiota in Vulvovaginal Candidiasis.

Pathogens 2022 May 25;11(6). Epub 2022 May 25.

Department of Medical Microbiology, Faculty of Medicine and Health Sciences, University Putra Malaysia, Serdang 43300, Selangor, Malaysia.

Vulvovaginal candidiasis (VVC) is a prevalent gynaecological disease characterised by vaginal wall inflammation that is caused by species. VVC impacts almost three-quarters of all women throughout their reproductive years. As the vaginal mucosa is the first point of contact with microbes, vaginal epithelial cells are the first line of defence against opportunistic infection by providing a physical barrier and mounting immunological responses.

Efficacy of Cochleated Amphotericin B in Mouse and Human Mucocutaneous Candidiasis.

Antimicrob Agents Chemother 2022 Jun 14:e0030822. Epub 2022 Jun 14.

Laboratory of Clinical Immunology & Microbiology, National Institute of Allergy & Infectious Diseases (NIAID), National Institutes of Health (NIH), Bethesda, MD, USA.

Candida albicans causes debilitating, often azole-resistant, infections in patients with chronic mucocutaneous candidiasis (CMC). Amphotericin B (AMB) resistance is rare, but AMB use is limited by parenteral administration and nephrotoxicity. In this study, we evaluated cochleated AMB (CAMB), a new oral AMB formulation, in mouse models of oropharyngeal candidiasis (OPC) and vulvovaginal candidiasis (VVC) and in patients with azole-resistant CMC.

Bimekizumab for psoriasis.

Drugs Today (Barc) 2022 Jun;58(6):273-282

Department of Dermatology, Centro Hospitalar do Porto, Porto, Portugal.

Psoriasis is a chronic, immune-mediated, inflammatory skin disease, affecting 1% to 3% of the population in Western countries. Due to advances in the understanding of psoriasis pathogenesis, in particular, the role of the interleukin-23 (IL-23)/T-helper 17 (Th17) immune axis, highly effective, targeted biologic therapies have been developed, shifting the psoriasis treatment paradigm. However, some patients do not respond or lose response to these novel therapies. Read More

Immunological effects of anti-IL-17/12/23 therapy in patients with psoriasis complicated by Candida infections.

J Invest Dermatol 2022 Jun 2. Epub 2022 Jun 2.

Department of Internal Medicine, Radboud University Medical Center, Nijmegen, the Netherlands; Radboud Center for Infectious Disease (RCI), Radboud University Medical Center, Nijmegen, the Netherlands; Department of Immunology and Metabolism, Life and Medical Sciences Institute (LIMES), University of Bonn, Bonn, Germany.

Biologics that block the T-helper-17 pathway are very effective in the treatment of psoriasis and other inflammatory diseases. However, interleukin-17 is also crucial for antifungal host defense, and clinical trial data suggest an increase in the incidence of Candida infections during IL-17 inhibitor (IL-17i) therapy. We investigated the innate and adaptive immune responses of psoriasis patients with a history of skin and/or mucosal candidiasis during IL-17i or IL-12/23i therapy, comparing those responses to healthy controls.

Radiation Exposure Perturbs IL-17RA-Mediated Immunity Leading to Changes in Neutrophil Responses That Increase Susceptibility to Oropharyngeal Candidiasis.

J Fungi (Basel) 2022 May 10;8(5). Epub 2022 May 10.

Department of Biological Sciences, University of Toledo, Toledo, OH 43606, USA.

Fungal infections caused by are a serious problem for immunocompromised individuals, including those undergoing radiotherapy for head and neck cancers. Targeted irradiation causes inflammatory dysregulation and damage to the oral mucosa that can be exacerbated by candidiasis. Post-irradiation the cytokine interleukin-17 (IL-17) protects the oral mucosae by promoting oral epithelial regeneration and balancing the oral immune cell populations, which leads to the eventual healing of the tissue.

Candida albicans commensalism in the oral mucosa is favoured by limited virulence and metabolic adaptation.

PLoS Pathog 2022 04 11;18(4):e1010012. Epub 2022 Apr 11.

Section of Immunology, Vetsuisse Faculty, University of Zürich, Zürich, Switzerland.

As part of the human microbiota, the fungus Candida albicans colonizes the oral cavity and other mucosal surfaces of the human body. Commensalism is tightly controlled by complex interactions of the fungus and the host to preclude fungal elimination but also fungal overgrowth and invasion, which can result in disease. As such, defects in antifungal T cell immunity render individuals susceptible to oral thrush due to interrupted immunosurveillance of the oral mucosa. Read More
