Abad CLR, Razonable RR. A review of endemic mycoses after hematopoietic stem cell transplantation. Transpl Infect Dis 2023; 25:e14155.

Abstract
BACKGROUND Endemic mycoses after hematopoietic stem cell transplantation (HSCT) are rarely reported. We aimed to comprehensively review the clinical presentation and outcomes of endemic mycoses in this immunocompromised population. METHODS Multiple databases were reviewed from inception through May 31, 2023 using endemic fungi as keywords (e.g., coccidioides, histoplasma, blastomyces, talaromyces, and paracoccidioides). Only hematopoietic transplants were included. RESULTS There were 16 publications on endemic mycoses after HSCT that reported nine unique cases of histoplasmosis, seven coccidioidomycosis, and two talaromycosis. No cases of paracoccidioides and blastomycoses were identified. Fifteen cases were allogeneic hematopoietic transplant recipients and three were autologous. Many were male (14/18, 77.8%) and overall median age was 50 (range 21-75) years. Among the 16 patients with coccidiodomycosis or histoplasmosis, fever, cytopenias and disseminated disease were the most common clinical presentations, with median onset of 8 or 12 months after HSCT, respectively. Likewise, the two HSCT patients with talaromycosis presented with disseminated disease at 12 and 48 months after transplantation. The vast majority were not on effective azole prophylaxis at the time of presentation, and many had recent intensification of immunosuppression. Nine of 18 patients died (50%), and all deaths occurred among patients with disseminated endemic mycoses. CONCLUSION Endemic mycoses among HSCT are uncommon. Onset was late, after discontinuation of azole prophylaxis, or was associated with intensification of immunosuppression. Disseminated disease was a common presentation, manifested by fever and cytopenias. Attributable mortality was high, and emphasizes the need for a high index of clinical suspicion so that prompt diagnosis and treatment is provided.

Abstract
Histoplasma capsulatum is an opportunistic pathogen which can lead to a wide variety of clinical presentations in the immunocompromised host. Post-transplant histoplasmosis in hematopoietic cell transplant recipients is exceedingly rare, with an incidence of <1%. We present a case of acute caecal perforation resulting from disseminated histoplasmosis in a patient who had undergone autologous bone marrow transplant for plasma cell dyscrasia. This is a 71-year-old patient who initially presented due to progressive weakness associated with shortness of breath.

Histoplasma capsulatum Infection in an Allogeneic Hematopoietic Stem Cell Transplant Patient Receiving Voriconazole Prophylaxis. Case Rep Hematol 2020; 2020:8124137.

Abstract
Histoplasma capsulatum infection is a rare complication in the allogeneic stem cell transplant patients. Minimal guidance exists on how to appropriately manage histoplasmosis in these patients. We report a patient who developed Histoplasma pneumonia while receiving voriconazole prophylaxis at a therapeutic trough level. The patient experienced significant clinical improvement after initiation of itraconazole pharmacotherapy. We recommend a lower threshold for evaluation for histoplasmosis in allogeneic hematopoietic stem cell transplant recipients who live in endemic regions, regardless of their antifungal prophylactic regimen.

Abstract
Histoplasma capsulatum is a dimorphic fungus that most often causes asymptomatic infection in the immunocompetent population. In immunocompromised patients, including solid organ transplant (SOT) and hematopoietic cell transplant (HCT) recipients, however, it is likely to cause severe life-threatening infection. Post-transplant histoplasmosis (PTH) in SOT is uncommon with an incidence of ≤1% and is even rarer in HCT patients. The majority of PTH in SOT is diagnosed in the first 2 years following transplantation. Histoplasmosis may result from endogenous reactivation of latent infection, de novo post-transplant acquisition, and donor-derived infection. Disseminated infection is common. Fever is the most common symptom and clinical features are often nonspecific, but patients with disseminated infection may present with a septic picture. Other features, including pancytopenia and hepatosplenomegaly, may not be prominent early in the course of illness. Contemporary histoplasma antigen assays are the most sensitive tests but cross-reactivity with antigens of other fungi, including with Aspergillus galactomannan, is not uncommon. Treatment should be continued for at least a year. Histoplasma antigen levels have prognostic value and can be used to monitor the response to therapy. The attributable mortality is approximately 10%. Routine screening of donors and recipients is not currently recommended.

Infections in Hematopoietic Cell Transplant Recipients: Results From the Organ Transplant Infection Project, a Multicenter, Prospective, Cohort Study. Open Forum Infect Dis 2017; 4:ofx050. [PMID: 28491889 PMCID: PMC5419070 DOI: 10.1093/ofid/ofx050] [Citation(s) in RCA: 76] [Impact Index Per Article: 10.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2016] [Accepted: 03/16/2017] [Indexed: 12/12/2022] Open
Abstract
Background Infection is a major cause of morbidity and mortality after allogeneic hematopoietic cell transplantation (HCT). Our object was to better define the epidemiology and outcomes of infections after HCT. Methods This was a prospective, multicenter cohort study of HCT recipients and conducted from 2006 to 2011. The study included 4 US transplant centers and 444 HCT recipients. Data were prospectively collected for up to 30 months after HCT using a standardized data collection tool. Results The median age was 53 years, and median follow up was 413 (range, 5–980) days. The most common reason for HCT was hematologic malignancy (87%). The overall crude mortality was 52%. Death was due to underlying disease in 44% cases and infection in 21%. Bacteremia occurred in 231 (52%) cases and occurred early posttransplant (median day 48). Gram-negative bloodstream infections were less frequent than Gram-positive, but it was associated with higher mortality (45% vs 13%, P = .02). Clostridium difficile infection developed in 148 patients (33%) at a median of 27 days post-HCT. There were 53 invasive fungal infections (IFIs) among 48 patients (11%). The median time to IFI was 142 days. Of 155 patients with cytomegalovirus (CMV) infection, 4% had CMV organ involvement. Varicella zoster infection (VZV) occurred in 13 (4%) cases and was disseminated in 2. Infection with respiratory viruses was seen in 49 patients. Pneumocystis jirovecii pneumonia was rare (1%), and there were no documented cases of nocardiosis, toxoplasmosis, endemic mycoses, or mycobacterial infection. This study lacked standardized antifungal and antiviral prophylactic strategies. Conclusions Infection remains a significant cause of morbidity and mortality after HCT. Bacteremias and C difficile infection are frequent, particularly in the early posttransplant period. The rate of IFI is approximately 10%. Organ involvement with CMV is infrequent, as are serious infections with VZV and herpes simplex virus, likely reflecting improved prevention strategies.

Abstract
Histoplasmosis causes a wide spectrum of clinical illness, including disseminated infection in the immunocompromised. We report a case of pulmonary histoplasmosis in an allogeneic stem cell transplant recipient and review the literature on this topic. Histoplasmosis in this patient population is uncommon, but it is associated with poor outcome.
