Abstract
Visceral mycoses (VM) are a deadly common infection in patients with acute leukemia and myelodysplastic syndrome (MDS). We retrospectively analyzed the data from the centralized "Annual Report of Autopsy Cases in Japan" that archives the national autopsy cases since 1989. Among the total of 175,615 archived autopsy cases, 7183 cases (4.1%) were acute leukemia and MDS patients. While VM was only found in 7756 cases (4.4% in total cases), we found VM had a disproportionally high prevalence among acute leukemia and MDS patients: 1562 VM cases (21.7%) and nearly sixfold higher in prevalence. Aspergillus spp. was the most predominant causative agent (45.0%), and Candida spp. was the second (22.7%) among confirmed single pathogen involved cases. The prevalence of Candida spp. infection decreased about 50% due to the widely use of fluconazole prophylaxis, which may skew toward doubling of the Mucormycetes incidence compared to 30 years ago. Complicated fungal infection (> one pathogen) was 11.0% in acute leukemia and MDS in 2015. It was 14.7 times higher than in other populations. Among 937 patients who received allogeneic hematopoietic cell transplantation (HCT), the prevalence of VM was 28.3% and 23.3% with GVHD. Aspergillus spp. was less prevalent, but Candida spp. was more associated with GVHD. Its prevalence remains stable. Although Aspergillus spp. was the primary causative agent, non-albicans Candida spp. was increasing as a breakthrough infection especially in GVHD cases. Complicated pathogen cases were more common in acute leukemia and MDS.

Echinocandins versus non-echinocandins for empirical antifungal therapy in patients with hematological disease with febrile neutropenia: A systematic review and meta-analysis. J Infect Chemother 2020; 26:596-603. [PMID: 32171659 DOI: 10.1016/j.jiac.2020.01.015] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2019] [Revised: 01/16/2020] [Accepted: 01/28/2020] [Indexed: 01/05/2023]
Abstract
Empirical antifungal therapy is recommended in high-risk patients who have persistent febrile neutropenia (FN) despite broad-spectrum antibiotic therapy. Based on high-quality evidence, most guidelines recommend caspofungin. The aim of this study was to clarify whether echinocandins, including micafungin, are associated with improved clinical outcomes in patients with persistent FN. We conducted a meta-analysis of randomized controlled trials (RCTs) of empirical therapy with echinocandins and non-echinocandins for FN in patients with hematological disease. The primary outcome was all-cause mortality within 7 days after completion of therapy. Secondary outcomes included treatment success, and discontinuation of therapy because of adverse events. For subgroup analysis, we compared RCTs of echinocandins with liposomal amphotericin B. Six RCTs (four that evaluated caspofungin and two that evaluated micafungin) were included in the meta-analysis. Mortality and adverse events in echinocandin-treated patients were significantly lower than in those treated with non-echinocandins [risk ratio (RR) 0.70, 95% confidence interval (CI) 0.49-0.99; RR 0.48, 95% CI 0.33-0.71, respectively]. There was no significant difference in treatment success (RR 1.09, 95% CI 0.87-1.36). Mortality and adverse events in echinocandin-treated patients were significantly lower than in those treated with liposomal amphotericin B (RR 0.68, 95% CI 0.46-0.99; RR 0.53, 95% CI 0.37-0.74, respectively). In conclusion, patients with persistent FN treated with echinocandins had decreased risk of death and adverse events. Both caspofungin and micafungin may be recommended as first-line empirical antifungal therapy in these patients. However, the small number of enrolled patients and the lack of RCTs involving pediatric patients should be considered when using micafungin.

Galactomannan and PCR in the Central Nervous System to Detect Invasive Mold Disease - A Retrospective Analysis in Immunocompromised Children. Sci Rep 2019; 9:12950. [PMID: 31506548 PMCID: PMC6736859 DOI: 10.1038/s41598-019-49426-0] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2019] [Accepted: 08/23/2019] [Indexed: 01/01/2023] Open
Abstract
Invasive mold disease (IMD) of the central nervous system (CNS) is a severe infectious complication in immunocompromised patients, but early microbiological diagnosis is difficult. As data on the value of biomarkers in the CNS are scarce, in particular in children, we retrospectively analyzed the performance of galactomannan (GM) and PCR assays in CNS samples of 15 children with proven and probable CNS IMD and of 32 immunocompromised children without fungal infection. Galactomannan in the cerebrospinal fluid (CSF) was assessed in nine of the 15 pediatric patients and was positive in five of them. Polymerase chain reaction (PCR) was performed in eight of the 15 patients and detected nucleic acids from molds in six patients. Galactomannan and PCR in CNS samples were the only positive microbiologic parameter in the CNS in three and two patients, respectively. In four patients, PCR specified the pathogen detected in microscopy. Galactomannan and PCR results remained negative in the CSF of all immunocompromised children without evidence for CNS IMD. Our data suggest that GM and PCR in CNS specimens are valuable additional tools in diagnosing CNS IMD and should be included in the work up of all pediatric patients with suspected mold disease of the CNS.
