Abad CLR, Razonable RR. Clinical Characteristics and Outcomes of Endemic Mycoses After Solid Organ Transplantation: A Comprehensive Review. Open Forum Infect Dis 2024; 11:ofae036. [PMID: 38444820 PMCID: PMC10913849 DOI: 10.1093/ofid/ofae036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Accepted: 01/18/2024] [Indexed: 03/07/2024] Open
Abstract
Background Geographically endemic fungi can cause significant disease among solid organ transplant (SOT) recipients. We provide an update on the epidemiology, clinical presentation, and outcomes of 5 endemic mycoses in SOT recipients. Methods Multiple databases were reviewed from inception through May 2023 using key words for endemic fungi (eg, coccidioidomycosis or Coccidioides, histoplasmosis or Histoplasma, etc). We included adult SOT recipients and publications in English or with English translation. Results Among 16 cohort studies that reported on blastomycosis (n = 3), coccidioidomycosis (n = 5), histoplasmosis (n = 4), and various endemic mycoses (n = 4), the incidence rates varied, as follows: coccidioidomycosis, 1.2%-5.8%; blastomycosis, 0.14%-0.99%; and histoplasmosis, 0.4%-1.1%. There were 204 reports describing 268 unique cases of endemic mycoses, including 172 histoplasmosis, 31 blastomycosis, 34 coccidioidomycosis, 6 paracoccidioidomycosis, and 25 talaromycosis cases. The majority of patients were male (176 of 261 [67.4%]). Transplanted allografts were mostly kidney (192 of 268 [71.6%]), followed by liver (n = 39 [14.6%]), heart (n = 18 [6.7%]), lung (n = 13 [4.9%]), and combined kidney-liver and kidney-pancreas (n = 6 [2.7%]). In all 5 endemic mycoses, most patients presented with fever (162 of 232 [69.8%]) and disseminated disease (179 of 268 [66.8%]). Cytopenias were frequently reported for histoplasmosis (71 of 91 [78.0%]), coccidioidomycosis (8 of 11 [72.7%]) and talaromycosis (7 of 8 [87.5%]). Graft loss was reported in 12 of 136 patients (8.8%). Death from all-causes was reported in 71 of 267 (26.6%); half of the deaths (n = 34 [50%]) were related to the underlying mycoses. Conclusions Endemic mycoses commonly present with fever, cytopenias and disseminated disease in SOT recipients. There is a relatively high all-cause mortality rate, including many deaths that were attributed to endemic mycoses.

Abstract
Osteoarticular mycoses are chronic debilitating infections that require extended courses of antifungal therapy and may warrant expert surgical intervention. As there has been no comprehensive review of these diseases, the International Consortium for Osteoarticular Mycoses prepared a definitive treatise for this important class of infections. Among the etiologies of osteoarticular mycoses are Candida spp., Aspergillus spp., Mucorales, dematiaceous fungi, non-Aspergillus hyaline molds, and endemic mycoses, including those caused by Histoplasma capsulatum, Blastomyces dermatitidis, and Coccidioides species. This review analyzes the history, epidemiology, pathogenesis, clinical manifestations, diagnostic approaches, inflammatory biomarkers, diagnostic imaging modalities, treatments, and outcomes of osteomyelitis and septic arthritis caused by these organisms. Candida osteomyelitis and Candida arthritis are associated with greater events of hematogenous dissemination than those of most other osteoarticular mycoses. Traumatic inoculation is more commonly associated with osteoarticular mycoses caused by Aspergillus and non-Aspergillus molds. Synovial fluid cultures are highly sensitive in the detection of Candida and Aspergillus arthritis. Relapsed infection, particularly in Candida arthritis, may develop in relation to an inadequate duration of therapy. Overall mortality reflects survival from disseminated infection and underlying host factors.

Infect Drug Resist 2022; 15:2879-2890. [PMID: 35686193 PMCID: PMC9172725 DOI: 10.2147/idr.s363362] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2022] [Accepted: 05/12/2022] [Indexed: 01/15/2023] Open
Abstract
Purpose To summarize the clinical characteristics, treatment and outcomes of transplant recipients infected with Talaromyces marneffei (TM). Materials and Methods A retrospective analysis was performed on 2 patients with Talaromycosis marneffei (TSM) and transplants at the First Affiliated Hospital of Guangxi Medical University, and a systematic literature review was conducted simultaneously. Results This article reported two patients after kidney transplantation who developed fever, cough within 3-4 months. Their haemoglobin was decreased. Their chest computed tomography (CT) showed nodules. TM was detected in their blood or bronchoalveolar lavage fluid samples by next-generation sequencing (NGS). After antifungal treatment with voriconazole (VOR), one patient worsened, the other patient died. A total of 21 patients with TSM after transplants were reported in the literature review. Fourteen underwent kidney transplantation, 4 underwent liver transplantation, 2 underwent lung transplantation, and 1 underwent bone marrow transplantation. The median time from initiating the postoperative immunosuppressive therapy to the onset of symptoms or disease changes was 18 (0.5-140) months. Among them, 9 patients developed fever, 7 patients developed cough or expectoration and 4 patients developed dyspnoea. Haemoglobin was decreased in 10 patients. Pulmonary nodules were found in 7 patients. Among the 21 patients, 7 were diagnosed by positive culture, 6 by biopsy, 5 by culture and biopsy. Of the 21 patients, 13 patients improved by antifungal therapy, 8 patients worsened or died. Seven patients who received amphotericin B followed by itraconazole (ITR) therapy all improved. Regarding the use of immunosuppressants in 12 patients, 9 patients had to discontinue or reduce their medications (6 patients improved, 3 patients worsened or died). Conclusion Patients with TSM after transplant often have disseminated infections, involving the respiratory, hematopoietic and so on. Fever, cough, decreased haemoglobin and pulmonary nodules often occur approximately 18 months after surgery. The combined applications of culture, biopsy, NGS are helpful for an early diagnosis. Antifungal therapy with amphotericin B followed by itraconazole is recommended, and the dosage of the immunosuppressant should be adjusted timely.

J Mycol Med 2021; 32:101214. [PMID: 34763148 DOI: 10.1016/j.mycmed.2021.101214] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Revised: 10/18/2021] [Accepted: 10/19/2021] [Indexed: 11/25/2022]
Abstract
Talaromyces (Penicillium) marneffei (T. marneffei) is an important pathogenic thermally dimorphic fungus in Southeast Asia that leads to a life-threatening systemic mycosis in immunodeficient hosts, especially in AIDS patients. With the increasing AIDS epidemic, the number of patients with T. marneffei infections in mainland China has increased rapidly in recent years. The infection can be life-threatening in people with immunodeficiencies, such as HIV, organ transplantations, autoimmune diseases, and malignant tumors. Here, we present a disseminated T. marneffei infection case in a renal transplant recipient successfully treated with voriconazole followed by itraconazole. We describe the patient's clinical progression from onset symptoms to recovery and review the additional 14 published cases with T. marneffei infections in renal transplant recipients. In addition, we discuss the route of infection and treatment strategies of T. marneffei. Our data suggest that patients with kidney transplantations in T. marneffei infection-endemic areas should presume the possibility of infection and initiate appropriate antifungal treatment.

Abstract
Talaromyces marneffei is one of the endemic mycoses prevalent in South-East Asian region. The infection, which was once considered to be opportunistic infection in HIV-positive patients, is establishing foothold in transplant and immunocompetent population. We report a case of a 41-year-old post-renal transplant female with a travel history to Assam two years back presenting with a subcutaneous lesion on right side of scalp associated with pain and blurring of vision in right eye. Fine-needle aspiration from the scalp lesion showed yeast cells with transverse septation in cytological examination and culture grew Talaromyces marneffei, which was confirmed by sequencing of ITS region. Patient was successfully managed with oral itraconazole 200 mg twice daily for ten months without subsequent recurrence. To our knowledge, this is the first case of subcutaneous infection by T. marneffei in a renal transplant recipient from India.

Abstract
Background Talaromyces marneffei infection is an important opportunistic infection associated with acquired immune deficiency syndrome (AIDS). However, it is unusual in patients with non-AIDS and other non-immunosuppressed conditions. We report a case of delayed diagnosis of disseminated T. marneffei infection in non-AIDS, non-immunosuppressive and non-endemic conditions. Case presentation We describe a previously healthy 24-year-old man who complained of a 3-month history of intermittent diarrhea and a recent week of uncontrollable high fever. The HIV antibody test was negative. Enhanced abdominal computed tomography (CT) and integrated 18F-2-deoxy-2-fluoro-D-glucose position emission tomography/computed tomography (FDG PET/CT) both suspected malignant lymphoma. However, a large number of yeast-like cells were found in macrophages in cervical lymph node samples by hematoxylin and eosin stain and silver hexamine stain. Subsequent blood culture suggested T. marneffei infection. Metagenomic Next Generation Sequencing (mNGS) results suggested T. marneffei as the dominant pathogen. Unfortunately, the patient continued to develop acute liver failure and died due to adverse events associated with amphotericin B. Conclusions Early diagnosis in HIV-negative patients who are otherwise not immunosuppressed and endemic poses a serious challenge. T. marneffei infection is an FDG-avid nonmalignant condition that may lead to false-positive FDG PET/CT scans. Nevertheless, integrated FDG PET/CT is necessary in patients with fever of unknown origin in the early period to perform earlier biopsy for histopathology and culture in highly avid sites and to avoid delays in diagnosis and treatment.

Abstract
These updated AST-IDCOP guidelines review the epidemiology, diagnosis, and management of emerging fungi after organ transplantation. Infections due to numerous generally innocuous fungi are increasingly recognized in solid organ transplant (SOT) recipients, comprising about 7%-10% of fungal infections in this setting. Such infections are collectively referred to as emerging fungal infections and include Mucormycetes, Fusarium, Scedosporium, and dematiaceous fungi among others. The causative organisms are diverse in their pathophysiology, uncommon in the clinical setting, have evolving nomenclature, and are often resistant to multiple commonly used antifungal agents. In recent years significant advances have been made in understanding of the epidemiology of these emerging fungal infections, with improved diagnosis and expanded treatment options. Still, treatment guidelines are generally informed by and limited to experience from cohorts of patients with hematological malignancies and/or solid and stem cell transplants. While multicenter randomized controlled trials are not feasible for these uncommon infections in SOT recipients, collaborative prospective studies can be valuable in providing information on the epidemiology, clinical manifestations, treatment strategies, and outcomes associated with the more commonly encountered infections.

Abstract
Talaromyces (Penicillium) marneffei is an important opportunistic fungal pathogen. It causes disseminated infection in immunocompromised patients especially in Southeast Asian countries. The pathogenicity of T. marneffei depends on the ability of the fungus to survive the killing process and replicate inside the macrophage. Major stresses inside the phagosome of macrophages are heat, oxidative substances and nutrient deprivation. The coping strategies of this pathogen with these stresses are under investigation. This paper summarizes factors relating to the stress responses that contribute to the intracellular survival of T. marneffei. These include molecules in the MAP signal transduction cascade, heat shock proteins, antioxidant enzymes and enzymes responsible in nutrient retrieval. There is speculation that the ability of T. marneffei to withstand these defenses plays an important role in its pathogenicity.

Talaromyces marneffei is an emerging opportunistic infection among immunocompromised patients. We observe the first native case of disseminated T. marneffei involving the kidney in a renal transplant recipient in mainland China. We describe the comprehensive clinical course, and ultrasound imaging of renal transplant biopsy, pathologic images, and electron microscopy observation of the biopsy specimen, highlighting the relevance of biopsy findings and the blood culture. We also focus on the treatment and good outcome of the patient. Then we review the literature and show the additional 10 reported cases of T. marneffei in renal transplant recipients. In addition, we discuss the new methods of rapid diagnosis of T. marneffei. In brief, timely diagnosis and proper treatment of T. marneffei infection is important in renal transplant recipients.

Abstract
Talaromyces (Penicillium) marneffei is an important pathogenic thermally dimorphic fungus causing systemic mycosis in Southeast Asia. The clinical significance of T. marneffei became evident when the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome epidemic arrived in Southeast Asia in 1988. Subsequently, a decline in the incidence of T. marneffei infection among HIV-infected patients was seen in regions with access to highly active antiretroviral therapy and other control measures for HIV. Since the 1990s, an increasing number of T. marneffei infections have been reported among non-HIV-infected patients with impaired cell-mediated immunity. Their comorbidities included primary adult-onset immunodeficiency due to anti-interferon-gamma autoantibodies and secondary immunosuppressive conditions including other autoimmune diseases, solid organ and hematopoietic stem cell transplantations, T-lymphocyte-depleting immunsuppressive drugs and novel anti-cancer targeted therapies such as anti-CD20 monoclonal antibodies and kinase inhibitors. Moreover, improved immunological diagnostics identified more primary immunodeficiency syndromes associated with T. marneffei infection in children. The higher case-fatality rate of T. marneffei infection in non-HIV-infected than HIV-infected patients might be related to delayed diagnosis due to the lack of clinical suspicion. Correction of the underlying immune defects and early use of antifungals are important treatment strategies. Clinicians should be familiar with the changing epidemiology and clinical management of T. marneffei infection among non-HIV-infected patients.

Abstract
Penicillium marneffei is a thermally dimorphic fungus that can cause severe opportunistic infections in endemic regions of Southeast Asia, particularly in individuals infected with human immunodeficiency virus-1, but has rarely been reported in solid organ transplant recipients. Herein, we report the first case, to our knowledge, of P. marneffei infection in a lung transplant recipient, occurring in a 41-year-old woman 28 months post lung transplantation, after recent travel to Vietnam. We have reviewed the literature to derive some management principles for this rare infection in this clinical context. The number of P. marneffei infections in transplant recipients may increase, as a result of increasing rates of transplantation and travel to endemic areas.

Abstract
Acquired immunodeficiency due to autoantibody against gamma interferon has recently been associated with opportunistic nontuberculous mycobacteriosis, especially among Southeast Asians. We report another 8 cases, all except one apparently immunocompetent hosts who suffered from concomitant or sequential infections by other intracellular pathogens causing penicilliosis, extraintestinal nontyphoidal salmonellosis, and burkholderiosis. The only case with an underlying immunodeficiency syndrome had systemic lupus erythematosus that was quiescent throughout the multiple infective episodes. Eight out of 10 (80.0%) patients with serological evidence of penicilliosis, 5 out of 7 (71.4%) with culture-positive extraintestinal nontyphoidal salmonellosis, 5 out of 28 (17.9%) with serological evidence of melioidosis, and 7 out of 13 (53.8%) with culture-positive nontuberculous mycobacteriosis possessed autoantibody against gamma interferon, whereas only 1 out of 100 patients with systemic lupus erythematosus did. Our study represents the first and largest case series linking this emerging immunodeficiency syndrome with these atypical infections in apparently immunocompetent hosts. Thus, we advocate that any patient with unexplained recurrent or polymicrobial infections due to these intracellular pathogens should be screened for acquired immunodeficiency due to autoantibody against gamma interferon.

Abstract
BACKGROUND/PURPOSE Penicillium marneffei is an emerging opportunistic pathogen. The goal of this study was to study its clinical and radiographic presentation, and the diagnostic value of a cytological study of penicilliosis. METHODS A total of 24 patients with penicilliosis were found by culture in an 8-year period. Thirteen patients had cytological examination, which were retrospectively reviewed to analyze the morphological characteristics of P. marneffei and diagnostic yields of different cytological specimens. RESULTS Twenty (83%) of the 24 patients (20 males) had human immunodeficiency virus (HIV) infection. In eight (40%) patients, penicilliosis was the initial manifestation of HIV infection. Penicilliosis was diagnosed in all patients antemortem from culture of blood or other body sites. One (4%) died. Six of 13 patients who had cytological study had intra- or extracellular yeast-like organisms with transverse septum found in fine needle aspirate, imprint or sputum cytology studies. The cytological diagnostic yields for P. marneffei from lung biopsy imprint smears, lung aspirates, neck lymph node aspirates and sputum were 2/2, 2/4, 2/2 and 2/4, respectively. The cytological diagnosis could be made immediately after aspiration, much quicker than diagnosis from cultures. CONCLUSION P. marneffei causes disseminated infection, and can be the initial manifestation in HIV-infected patients in Taiwan. Penicilliosis can be diagnosed rapidly with cytological study of lung biopsy imprint smears, lung aspirates, neck lymph node aspirates or sputum.

Abstract
PURPOSE OF REVIEW Since the start of the HIV pandemic, systemic infection with Penicillium marneffei has developed from a very rare diagnosis to the third most common opportunistic infection in HIV co-infected patients in South East Asia. HIV patients who have travelled to or lived in Asia may present with this infection in nonendemic countries, and it has therefore become important for all those working in the field of HIV to recognize, understand and treat this emerging disease. RECENT FINDINGS The clinical features, diagnosis and treatment of this infection are reviewed. Recent data exploring antigen-based serodiagnostics, the role of newer antifungals such as voriconazole, and the possibility of discontinuation of secondary prophylaxis after immune restoration from highly active antiretrovirals are discussed. SUMMARY Large series from endemic areas and case reports from nonendemic regions have been published and provide insights into clinical features and presentation. Novel diagnostics are evolving, with galactomannan and other assays looking promising. Present therapy is largely based on noncontrolled studies, and further research into optimal therapy and the potential to discontinue secondary itraconazole prophylaxis is required.

Abstract
Although species of Aspergillus and Candida account for most deeply invasive and life-threatening fungal infections, the past decades have seen a rise in the immunocompromised population. With this increase, additional fungi have emerged as important agents of morbidity and mortality. These opportunistic fungi are characterized by their ubiquitous presence in the environment, their ability to cause disease in immunosuppressed patients, and their diminished susceptibility to the currently available antifungal agents. Pneumonia, one aspect of a myriad of clinical manifestations caused by these fungal pathogens, is discussed in this article.

Abstract
The clinical spectrum of AIDS and changes of morbidity and mortality associated with HIV infection following initiation of highly active antiretroviral therapy (HAART) are rarely described in the less developed countries in the Asia-Pacific region. We prospectively observed on a follow-up basis 309 HIV-infected patients (82.8% with AIDS) at National Taiwan University Hospital in Taiwan, where highly active antiretroviral therapy (HAART) has been provided to all patients at no charge at any stage of HIV infection since April 1, 1997, to describe the spectrum of HIV-associated opportunistic diseases and evaluate changes of morbidity and mortality from June 24, 1994 through June 23, 1999. Of the patients, 59.3% at study entry had a CD4+ lymphocyte count of <50 cells/microliter. The five leading HIV-associated opportunistic infections included oroesophageal candidiasis (195 patients), Pneumocystis carinii pneumonia (93), tuberculosis (77), mucocutaneous herpes simplex infection (74), and cytomegalovirus diseases (73). The incidence rates of seven major AIDS-defining opportunistic diseases were declining though the changes of the relative proportions varied. The median duration of hospitalization decreased from 36 days in 1995 to 12 days in 1999 (p =.0001). Overestimated mortality rate declined from 148.4 per 100 patient-years in 1995 to 7.4 per 100 patient-years in 1999 (p =.0001) whereas the underestimated mortality rate declined from 110.5 to 5.39 per 100 patient-years (p =.0001). Risk ratio (RR) for mortality in patients who received HAART compared with those who did not was 0.410 (95% confidence interval [CI], 0.249-0.674; p =.0004) and the RR was 0.250 (95% CI, 0.127-0.492; p =.0001) when the analysis was limited to patients with an initial CD4+ lymphocyte count <100 cells/microliter and follow-up duration >30 days after adjusting for their age, gender, type of risk behavior, and CD4+ lymphocyte count. Morbidity and mortality were declining with each study year even in a population consisting mainly of patients at the advanced stage of HIV infection in Taiwan. Earlier diagnosis, accumulation of clinical experience, and use of HAART were associated with lower mortality rates.

Abstract
Most species of Penicillium are considered relatively benign with respect to causing human disease. However, one species, P. marneffei, has emerged as a significant pathogen particularly among individuals who live in Southeast Asia and are concurrently infected with the human immunodeficiency virus. While environmental and epidemiological studies have yet to resolve the reason for the heightened virulence of P. marneffi, one characteristic does distinguish this fungus from other Penicillium species. Whereas the latter grow as monomorphic moulds bearing typical asexual propagules (conidia), P. marneffei is thermally dimorphic. At room temperature, P. marneffei exhibits the morphology characteristic of the genus. In contrast to other Penicillia, though, P. marneffei grows as a yeast-like entity (arthroconidium) when found in diseased tissue or cultivated at 37 degrees C. Studies in our laboratory have focused on the differential gene expression between the mould and arthroconidial phases. Many of the genes whose expression differs during mould-to-arthrocondium transition are related to energy metabolism. A better understanding of gene expression during morphogenesis in P. marneffei may help detect unique target sites or cellular processes that can be exploited in the development of antifungal agents or immunomodulation therapies.

Abstract
Penicilliosis marneffei, a common mycosis among AIDS patients living in Southeast Asia, has been recently suggested for inclusion in the AIDS surveillance case definition. Infections with Penicillium marneffei were rare in the past, but infections with this dimorphic fungus have increased with the endemic of AIDS in the region. The reservoir of P. marneffei in nature is still unknown, although it seems likely that inhalation may be the route of entry of the organism leading to infection in humans. P. marneffei can cause two clinical types of the disease; focal and fatal progressive, disseminated infections, characterized by a variety of symptoms which can mimic those of other diseases. Oral P. marneffei lesions usually occur in patients with disseminated infections, presenting as shiny papules, as erosions or as shallow ulcers covered with whitish yellow, necrotic slough which may be found on the palate, gingiva, labial mucosa, tongue and oropharynx. Biopsy and culture provide definitive diagnoses, while serologic tests for both antibody and antigen are useful in rapid presumptive diagnoses as well as in surveillance studies of the prevalence and latency of the infection. Penicilliosis marneffei is a treatable disease, but late diagnosis and treatment may be fatal. Itraconazole and ketoconazole are the drugs of first choice for mild to moderately severe forms of the disease, whereas parenteral therapy with amphotericin B may be required for seriously ill patients. Recurrence of the disease is common, therefore maintenance is recommended. As reported, prophylaxis generating resistant strains are likely to develop.
