Item Open Access Coronavirus Disease 2019-Associated Invasive Fungal Infection.(Open forum infectious diseases, 2021-12) Baddley, John W; Thompson, George R; Chen, Sharon C-A; White, P Lewis; Johnson, Melissa D; Nguyen, M Hong; Schwartz, Ilan S; Spec, Andrej; Ostrosky-Zeichner, Luis; Jackson, Brendan R; Patterson, Thomas F; Pappas, Peter GCoronavirus disease 2019 (COVID-19) can become complicated by secondary invasive fungal infections (IFIs), stemming primarily from severe lung damage and immunologic deficits associated with the virus or immunomodulatory therapy. Other risk factors include poorly controlled diabetes, structural lung disease and/or other comorbidities, and fungal colonization. Opportunistic IFI following severe respiratory viral illness has been increasingly recognized, most notably with severe influenza. There have been many reports of fungal infections associated with COVID-19, initially predominated by pulmonary aspergillosis, but with recent emergence of mucormycosis, candidiasis, and endemic mycoses. These infections can be challenging to diagnose and are associated with poor outcomes. The reported incidence of IFI has varied, often related to heterogeneity in patient populations, surveillance protocols, and definitions used for classification of fungal infections. Herein, we review IFI complicating COVID-19 and address knowledge gaps related to epidemiology, diagnosis, and management of COVID-19-associated fungal infections.Item Open Access Global guideline for the diagnosis and management of the endemic mycoses: an initiative of the European Confederation of Medical Mycology in cooperation with the International Society for Human and Animal Mycology.(The Lancet. Infectious diseases, 2021-12) Thompson, George R; Le, Thuy; Chindamporn, Ariya; Kauffman, Carol A; Alastruey-Izquierdo, Ana; Ampel, Neil M; Andes, David R; Armstrong-James, Darius; Ayanlowo, Olusola; Baddley, John W; Barker, Bridget M; Lopes Bezerra, Leila; Buitrago, Maria J; Chamani-Tabriz, Leili; Chan, Jasper FW; Chayakulkeeree, Methee; Cornely, Oliver A; Cunwei, Cao; Gangneux, Jean-Pierre; Govender, Nelesh P; Hagen, Ferry; Hedayati, Mohammad T; Hohl, Tobias M; Jouvion, Grégory; Kenyon, Chris; Kibbler, Christopher C; Klimko, Nikolai; Kong, David CM; Krause, Robert; Lee Lee, Low; Meintjes, Graeme; Miceli, Marisa H; Rath, Peter-Michael; Spec, Andrej; Queiroz-Telles, Flavio; Variava, Ebrahim; Verweij, Paul E; Schwartz, Ilan S; Pasqualotto, Alessandro CThe global burden of the endemic mycoses (blastomycosis, coccidioidomycosis, emergomycosis, histoplasmosis, paracoccidioidomycosis, sporotrichosis, and talaromycosis) continues to rise yearly and these infectious diseases remain a leading cause of patient morbidity and mortality worldwide. Management of the associated pathogens requires a thorough understanding of the epidemiology, risk factors, diagnostic methods and performance characteristics in different patient populations, and treatment options unique to each infection. Guidance on the management of these infections has the potential to improve prognosis. The recommendations outlined in this Review are part of the "One World, One Guideline" initiative of the European Confederation of Medical Mycology. Experts from 23 countries contributed to the development of these guidelines. The aim of this Review is to provide an up-to-date consensus and practical guidance in clinical decision making, by engaging physicians and scientists involved in various aspects of clinical management.Item Open Access The Antifungal Pipeline: Fosmanogepix, Ibrexafungerp, Olorofim, Opelconazole, and Rezafungin.(Drugs, 2021-10) Hoenigl, Martin; Sprute, Rosanne; Egger, Matthias; Arastehfar, Amir; Cornely, Oliver A; Krause, Robert; Lass-Flörl, Cornelia; Prattes, Juergen; Spec, Andrej; Thompson, George R; Wiederhold, Nathan; Jenks, Jeffrey DThe epidemiology of invasive fungal infections is changing, with new populations at risk and the emergence of resistance caused by the selective pressure from increased usage of antifungal agents in prophylaxis, empiric therapy, and agriculture. Limited antifungal therapeutic options are further challenged by drug-drug interactions, toxicity, and constraints in administration routes. Despite the need for more antifungal drug options, no new classes of antifungal drugs have become available over the last 2 decades, and only one single new agent from a known antifungal class has been approved in the last decade. Nevertheless, there is hope on the horizon, with a number of new antifungal classes in late-stage clinical development. In this review, we describe the mechanisms of drug resistance employed by fungi and extensively discuss the most promising drugs in development, including fosmanogepix (a novel Gwt1 enzyme inhibitor), ibrexafungerp (a first-in-class triterpenoid), olorofim (a novel dihyroorotate dehydrogenase enzyme inhibitor), opelconazole (a novel triazole optimized for inhalation), and rezafungin (an echinocandin designed to be dosed once weekly). We focus on the mechanism of action and pharmacokinetics, as well as the spectrum of activity and stages of clinical development. We also highlight the potential future role of these drugs and unmet needs.
