Coronavirus disease 2019 (COVID-19)-associated invasive fungal infections are an important complication in a substantial number of critically ill, hospitalized patients with COVID-19. Three groups of fungal pathogens cause co-infections in COVID-19: Aspergillus, Mucorales and Candida species, including Candida auris. Here we review the incidence of COVID-19-associated invasive fungal infections caused by these fungi in low-, middle- and high-income countries. By evaluating the epidemiology,...

Background Antifungal stewardship (AFS) has emerged as an important component of quality in managing invasive fungal infections (IFIs), and cost-benefit calculations suggest regular training in AFS is well worth the effort. Methods This review will discuss the most common IFIs in solid organ transplantation (SOT)-recipients, how to diagnose them, and current recommendations for antifungal treatment and prophylaxis before demonstrating key takeaway points of AFS in this high-risk population....

Background The incidence and impact of de novo fungal airway colonization and infection in lung transplant recipients (LTRs) with known chronic lung allograft dysfunction (CLAD) has not been established. We aimed to determine the 1-year cumulative incidence and risk factors of de novo fungal colonization or infection in LTRs with CLAD and assess the impact of colonization or infection on post-CLAD survival. Methods Prospectively collected Toronto Lung Transplant Program database and chart...

Background Dematiaceous fungi cause a number of infectious syndromes referred to as phaeohyphomycosis among both immunocompetent and immunocompromised hosts. We performed a systematic review to characterize these infections in solid organ transplant recipients (SOTR). Methods We searched PubMed database (last searched 1/6/2022) for English-language reports on dematiaceous fungal infections in SOTR. Included reports needed individualized demographic, treatment, and outcome data; pediatric...

Background: Pneumocystis jirovecii pneumonia (PCP) is an opportunistic infection commonly affecting immunocompromised people. Diagnosis usually requires invasive techniques to obtain respiratory specimens. Minimally invasive detection tests have been proposed, but their operating characteristics are poorly described. Objectives: To systematically review and meta-analyse the performance of minimally invasive PCP detection tests to inform diagnostic algorithms. Data sources: Medline, Embase,...

Background Pulmonary mucormycosis has been associated with high mortality (reported up to 100%) in renal transplant recipients. Methods This was a retrospective analysis of renal transplant patients with pulmonary mucormycosis between April 2014 and March 2020, who underwent surgical resection of the affected lung along with liposomal amphotericin therapy. Patients with lower respiratory illness features underwent chest X-ray, high-resolution computed tomography of the chest, and those with...

In the era of prophylaxis, Pneumocystis pneumonia (PCP) has become a late-onset opportunistic infection requiring indications for prolonged prophylaxis to be defined. The primary objective of our study was therefore to evaluate risk factors associated with late-onset PCP. The secondary objective was to assess the impact of this infection on graft and patient survival.We conducted a French case-control study in Bordeaux and Toulouse center by matching 1 case to 1–2 controls from the same...

Export Background.  There is no consensus guidance on when to reinitiate Pneumocystis jirovecii pneumonia (PJP) prophylaxis in solid organ transplant (SOT) recipients at increased risk. The 2019 American Society of Transplantation Infectious Diseases Community of Practice (AST IDCOP) guidelines suggested to continue or reinstitute PJP prophylaxis in those receiving intensified immunosuppression for graft rejection, cytomegalovirus (CMV) infection, higher dose of...

Abstract Background Invasive candidiasis is the most common invasive fungal disease in children and adolescents, but there are limited pediatric-specific antifungal effectiveness data. We compared the effectiveness of echinocandins to triazoles or amphotericin B formulations (triazole/amphotericin B) as initial directed therapy for invasive candidiasis. Methods This multinational observational...

BACKGROUND: Cirrhosis is an end-stage liver disease and is reported as an independent risk factor for cryptococcosis. Information about cryptococcosis in patients with cirrhosis remains sparse. METHODS: Human immunodeficiency virus-uninfected patients with cryptococcosis and cirrhosis admitted to Huashan Hospital from July 2005 to June 2020 were reviewed. Efficacy and safety of antifungal treatments, clinical outcome, and prognostic factors of mortality were evaluated. RESULTS: A total of 49...

BACKGROUND: Solid organ transplant (SOT) recipients are at risk of Pneumocystis pneumonia (PCP). PCP is associated with significant morbidity and mortality. The effect of acute T cell-mediated rejection (TCMR) on post-transplant PCP has not been determined yet. METHODS: In this case-control study, we estimated the risk of PCP following acute TCMR during a lookback period of 180 days. We also determined the effects of contributing factors such as CMV infection. RESULTS: We compared 15 SOT (8...

SUMMARY Infections due to Aspergillus species are an acute threat to human health; members of the Aspergillus section Fumigati are the most frequently occurring agents, but depending on the local epidemiology, representatives of section Terrei or section Flavi are the second or third most important. Aspergillus terreus species complex is of great interest, as it is usually amphotericin B resistant and displays notable differences in immune interactions in comparison to Aspergillus fumigatus....

Invasive fungal infections (IFIs) are one of the most feared complications associated with liver transplantation, with high rates of morbidity and mortality. We discuss the most common invasive fungal infections in the setting of liver transplant, including Candida, Aspergillus, and Cryptococcal infections, and some less frequent but devastating mold infections. Further, we evaluate the use of prophylaxis to prevent invasive fungal infection in this population as a promising mechanism to...

The quest for new antifungal and antitubercular drugs is a need of the hour because of morbid co-pathogenesis and an increase in immunocompromised patients. One of the ways forward is to explore and repurpose the established pharmacophores for the desired application. Oxazolidinones are well-known antibacterial agents, with few investigations reported to exploit their antifungal properties. Herein, we report the design and synthesis of a series of linezolid-based oxazolidinones as potent...

<p>Invasive fungal infections threaten lung transplant outcomes with high associated morbidity and mortality. Pharmacologic prophylaxis may be key to prevent posttransplant invasive fungal infections, but cost, adverse effects, and absorption issues are barriers to effective prophylaxis. Trends in fungal infection diagnostic strategies utilize molecular diagnostic methodologies to complement traditional histopathology and culture techniques. While lung transplant recipients are susceptible...

Cryptococcus species can cause serious life-threatening infection in solid organ transplant recipients by reactivation of prior infection, post-transplant de novo infection, or donor transmission from the transplanted organ. Although previously reported in the literature, the extent of donor-derived cryptococcosis in the United States has not been documented. We analyzed potential donor-derived Cryptococcus transmission events reported to the Organ Procurement and Transplantation Network...

BACKGROUND: Aspergillus spp. of section Usti (A. ustus) represent a rare cause of invasive aspergillosis (IA). This multicenter study describes the epidemiology and outcome of A. ustus infections. METHODS: Patients with A. ustus isolated from any clinical specimen were retrospectively identified in 22 hospitals from 8 countries. When available, isolates were sent for species identification (BenA/CaM sequencing) and antifungal susceptibility testing. Additional cases were identified by review...
