Abstract
Chronic granulomatous disease (CGD) is caused by an impaired respiratory burst reaction in phagocytes. CGD is an X-linked (XL) (caused by pathogenic variants in CYBB) or autosomal recessive inborn error of immunity (caused by pathogenic variants in CYBA, NCF1, NCF2, or CYBC1). Female carriers of XL-CGD and unfavorable lyonization may present with the partial or full picture of CGD. Patients with CGD are at increased risk for invasive bacterial and fungal infections of potentially any organ, but especially the lymph nodes, liver, and lungs. Pathogens most frequently isolated are S. aureus and Aspergillus spp. Autoinflammation is difficult to control with immunosuppression, and patients frequently remain dependent on steroids. To diagnose CGD, reactive oxygen intermediates (O2 - or H2O2) generated by the NADPH oxidase in peripheral blood phagocytes are measured upon in vitro activation with either phorbol-12-myristate-13-acetate (PMA) and/or TLR4 ligands (E. coli or LPS). Conservative treatment requires strict hygienic conduct and adherence to antibiotic prophylaxis against bacteria and fungi, comprising cotrimoxazole and triazoles. The prognosis of patients treated conservatively is impaired: for the majority of patients, recurrent and/or persistent infections, autoinflammation, and failure to thrive remain lifelong challenges. In contrast, cellular therapies (allogeneic stem cell transplantation or gene therapy) can cure CGD. Optimal outcomes in cellular therapies are observed in individuals without ongoing infections or inflammation. Yet cellular therapies are the only curative option for patients with persistent fungal infections or autoinflammation.

Abstract
Since their description by Metchnikoff in 1905, phagocytes have been increasingly recognized to be the entities that traffic to sites of infection and inflammation, engulf and kill infecting organisms, and clear out apoptotic debris all the while making antigens available and accessible to the lymphoid organs for future use. Therefore, phagocytes provide the gateway and the first check in host protection and immune response. Disorders in killing and chemotaxis lead not only to infection susceptibility, but also to autoimmunity. We aim to describe chronic granulomatous disease and the leukocyte adhesion deficiencies as well as myeloperoxidase deficiency and G6PD deficiency as paradigms of critical pathways.

Abstract
Fungi are opportunists: They particularly require a defect of immunity to cause severe or disseminated disease. While often secondary to an apparent iatrogenic cause, fungal diseases do occur in the absence of one, albeit infrequently. These rare cases may be due to an underlying genetic immunodeficiency that can present variably in age of onset, severity, or other infections, and in the absence of a family history of disease. They may also be due to anti-cytokine autoantibodies. This review provides a background on how human genetics or autoantibodies underlie cases of susceptibility to severe or disseminated fungal disease. Subsequently, the lessons learned from these inborn errors of immunity marked by fungal disease (IEI-FD) provide a framework to begin to mechanistically decipher fungal syndromes, potentially paving the way for precision therapy of the mycoses.

Abstract
The Inonotuslinteus complex, predominantly reported from East Asia, Mesoamerica and Caribbean countries, was circumscribed into Tropicoporus as one of the new genera, based on morphological and phylogenetic data. The present paper describes four new species of Tropicoporus from India. Morphological characteristics and phylogenetic analyses, based on ITS and nLSU data, delimited the new species, which are named T.cleistanthicola, T.indicus, T.pseudoindicus and T.tamilnaduensis. The pairwise homoplasy index (PHI) test was done to confirm the distinctive nature of the new species. The traits of Indian species remain distinct from one another, except for the pileate basidiome with the mono-dimitic hyphal system, cystidioles and broadly ellipsoid basidiospores. Descriptions, illustrations, PHI test results and a phylogenetic tree to show the position of the new species are provided. In addition, an identification key to Tropicoporus in Asia and an African species is given.

Abstract
Chronic Granulomatosis Disease (CGD) is an inherited immune deficiency due to a mutation in the genes coding for the subunits of the NADPH oxidase enzyme that affects the oxidative capacity of phagocytic cells. It is characterized by increased susceptibility to bacterial and fungal infections, particularly Aspergillus, as well as complications associated with hyperinflammation and granulomatous tissue infiltration. There exist two types of frequently encountered pulmonary manifestations: (1) due to their being initially pauci-symptomatic, possibly life-threatening infectious complications are often discovered at a late stage. Though their incidence has decreased through systematic anti-bacterial and anti-fungal prophylaxis, they remain a major cause of morbidity and mortality; (2) inflammatory complications consist in persistent granulomatous mass or interstitial pneumoniae, eventually requiring immunosuppressive treatment. Pulmonary complications recurring since infancy generate parenchymal and bronchial sequelae that impact functional prognosis. Hematopoietic stem cell allograft is a curative treatment; it is arguably life-sustaining and may limit the morbidity of the disease. As a result of improved pediatric management, life expectancy has increased dramatically. That said, new challenges have appeared with regard to adults: difficulties of compliance, increased inflammatory manifestations, acquired resistance to anti-infectious therapies. These different developments underscore the importance of the transition period and the need for multidisciplinary management.

Abstract
Chronic granulomatous disease (CGD) is a primary immunodeficiency caused by a defect in the phagocytic function of the innate immune system owing to mutations in genes encoding the five subunits of the nicotinamide adenine dinucleotide phosphatase (NADPH) oxidase enzyme complex. This review aimed to provide a comprehensive approach to the pathogens associated with chronic granulomatous disease (CGD) and its management. Patients with CGD, often children, have recurrent life-threatening infections and may develop infectious or inflammatory complications. The most common microorganisms observed in the patients with CGD are Staphylococcus aureus, Aspergillus spp., Candida spp., Nocardia spp., Burkholderia spp., Serratia spp., and Salmonella spp. Antibacterial prophylaxis with trimethoprim-sulfamethoxazole, antifungal prophylaxis usually with itraconazole, and interferon gamma immunotherapy have been successfully used in reducing infection in CGD. Haematopoietic stem cell transplantation (HCT) have been successfully proven to be the treatment of choice in patients with CGD.

Abstract
Filamentous basidiomycetes are an emerging cause of human infection in tropical and subtropical regions. We report a case of subcutaneous infection caused by the shelf fungus, Megasporoporia setulosa, in an immunocompetent male. This is also the first report of human infection caused by this filamentous basidiomycete. Identification of the fungus could only be achieved by sequencing the ITS and LSU regions of rDNA. The patient recovered following surgery and treatment with amphotericin B and oral itraconazole. This report underscores the cross-kingdom pathogenicity of plant fungi and the importance of molecular tools for definitive identification of nonsporulating fungal species.

Abstract
In medical mycology, the main context of disease is iatrogenic-based disease. However, historically, and occasionally, even today, fungal diseases affect humans with no obvious risk factors, sometimes in a spectacular fashion. The field of “inborn errors of immunity” (IEI) has deduced at least some of these previously enigmatic cases; accordingly, the discovery of single-gene disorders with penetrant clinical effects and their immunologic dissection have provided a framework with which to understand some of the key pathways mediating human susceptibility to mycoses. By extension, they have also enabled the identification of naturally occurring auto-antibodies to cytokines that phenocopy such susceptibility. This review provides a comprehensive update of IEI and autoantibodies that inherently predispose humans to various fungal diseases.

Abstract
Purpose Chronic granulomatous disease (CGD) is an uncommon, inborn error of immunity. We updated our large, single-center US experience with CGD and describe some newly recognized features. Methods We retrospectively reviewed 26 patients seen from November 2013 to December 2019. Serious infections required intravenous antibiotics or hospitalization. Results There were 21 males and 5 females. The most frequent infectious agents at presentation were aspergillus (4), serratia (4), burkholderia (2), Staphylococcus aureus (2), and klebsiella (2). The most common serious infections at presentation were pneumonia (6), lymphadenitis (6), and skin abscess (3). Our serious infection rate was 0.2 per patient-year from December 2013 through November 2019, down from 0.62 per patient-year from the previous study period (March 1985–November 2013). In the last 6 years, four patients were evaluated for human stem cell transplantation, two were successfully transplanted, and we had no deaths. Several patients had unusual infections or autoimmune manifestations of disease, such as pneumocystis pneumonia, basidiomycete/phellinus fungal pneumonia, and retinitis pigmentosa. We included one carrier female with unfavorable Lyonization in our cohort. Conclusion We update of a large US single-center experience with CGD and describe some recently identified features of the illness.

Abstract
Background Chronic granulomatous disease (CGD) is a rare inherited primary immunodeficiency syndrome, manifested as recurrent infections and inflammatory complications. Although prophylactic treatment with antibiotics and antifungals improved the outcome of CGD patients, infections remain the major cause of mortality. Case presentation A boy aged 3 years and 8 months was admitted to hospital complaining of lip swelling with fever for half a month and neck abscess for 11 days. After a thorough examination, severe pneumonia, respiratory failure, oral and maxillofacial space infection, and perianal abscess were confirmed. However, his condition didn’t improve after initial comprehensive therapy. Subsequently, overlapping infections of Nocardia farcinica and Aspergillus fumigatus were identified by metagenomic next-generation sequencing. He was treated with imipenem, linezolid, and voriconazole intravenously, plus taking oral compound sulfamethoxazole. Later, his condition improved. Through whole-exome sequencing, the child was ultimately diagnosed as X-linked chronic granulomatous disease (X-CGD) caused by CYBB gene mutation. Allogeneic hematopoietic stem cell transplantation was the potential sanative approach but there were no available human leukocyte antigen compatible donors for the child. The family requested to transfer to a superior hospital for further treatment. Two months later, we followed up the child’s family. Unfortunately, the child had expired due to severe infection. Conclusion To our knowledge, this is the first case of overlapping infection of Nocardia farcinica and Aspergillus fumigatus identified by metagenomic next-generation sequencing in a child with X-CGD from China. For infectious pathogens that are hard to diagnosis by traditional detection methods, metagenomic next-generation sequencing is recommended as an adminicle or indispensable approach for microbial identification. Patients with X-CGD have poor prognosis, early diagnosis and intervention of X-CGD may reduce the mortality.

Abstract
Tropicoporus tropicalis is an environmental basidiomycete that has been implicated in nine cases of cutaneous (n = 7) and pulmonary (n = 2) human infections predominantly in chronic granulomatous disease patients. We report here the first case of keratitis caused by Tropicoporus tropicalis in a 40-year-old immunocompetent patient, who presented with sudden diminution of vision in right eye. Corneal scrapings revealed hyaline, septate hyphae in microscopy and culture showed growth of white non-sporulating mycelial growth which was confirmed as Tropicoporus tropicalis by sequencing of ITS region of 28S rDNA. The patient was initiated on topical voriconazole along with natamycin, gatifloxacin and atropine drops. However, despite treatment, corneal ulcer perforated, for which penetrating keratoplasty was performed. Thereafter, he was prescribed amphotericin B (AMB) drops sixteen times a day and ketoconazole 200 mg twice a day with no recurrence reported over one year of follow up. The case represents the first case of infection by this fungus from India and also is the first case to be reported in an immunocompetent host.

Abstract
PURPOSE OF REVIEW Fungal infections have steadily increased in incidence, emerging as a significant cause of morbidity and mortality in patients with iatrogenic immunosuppression. Simultaneously, we have witnessed a growing population of newly described inherited immune disorders that have enhanced our understanding of the human immune response against fungi. In the present review, we provide an overview and diagnostic roadmap to inherited disorders which confer susceptibility to superficial and invasive fungal infections. RECENT FINDINGS Inborn errors of fungal immunity encompass a heterogeneous group of disorders, some of which confer fungal infection-specific susceptibility, whereas others also feature broader infection vulnerability and/or noninfectious manifestations. Infections by Candida, Aspergillus, endemic dimorphic fungi, Pneumocystis, and dermatophytes along with their organ-specific presentations provide clinicians with important clues in the assessment of patients with suspected immune defects. SUMMARY The absence of iatrogenic risk factors should raise suspicion for inborn errors of immunity in children and young adults with recurrent or severe fungal diseases. Expeditious diagnosis and prompt initiation of antifungal therapy and management of complications are paramount to achieve remission of fungal disease in the setting of primary immunodeficiency disorders.

Abstract
PURPOSE OF REVIEW Invasive fungal infections (IFIs) most often occur secondary to acquired immunodeficiency states such as transplantation, AIDS or immune-modulatory treatment for neoplastic and autoimmune disorders. Apart from these acquired conditions, several primary immunodeficiency disorders (PIDs) can present with IFIs in the absence of iatrogenic immunosuppression. This review highlights recent advances in our understanding of PIDs that cause IFIs, which may help clinicians in the diagnosis and management of such infections. RECENT FINDINGS A growing number of PIDs that cause varying combinations of invasive infections by commensal Candida, inhaled molds (primarily Aspergillus), Cryptococcus, Pneumocystis, endemic dimorphic fungi, dermatophytes, and/or agents of phaeohyphomycosis has uncovered the organ- and fungus-specific requirements for effective antifungal host defense in humans. Employing certain diagnostic algorithms tailored to the infecting fungus can facilitate the genetic diagnosis of the underlying PID, which has implications for the optimal management of affected patients. SUMMARY Heightened clinical suspicion is required for the diagnosis of underlying genetic defects in patients who develop IFIs in the absence of acquired immunodeficiency. Early initiation of antifungal therapy followed by long-term secondary prophylaxis is typically needed to achieve remission, but hematopoietic stem-cell transplantation may sometimes be necessary to promote immune restoration and infection control.

Abstract
Chronic granulomatous disease (CGD) is a rare but serious primary immunodeficiency with varying prevalence and rates of X-linked and autosomal recessive disease worldwide. Functional defects in the phagocyte nicotinamide adenine dinucleotide phosphate oxidase complex predispose patients to a relatively narrow spectrum of bacterial and fungal infections that are sometimes fastidious and often difficult to identify. When evaluating and treating patients with CGD, it is important to consider their native country of birth, climate, and living situation, which may predispose them to types of infections that are atypical to your routine practice. In addition to recurrent and often severe infections, patients with CGD and X-linked female carriers are also susceptible to developing many non-infectious complications including tissue granuloma formation and autoimmunity. The DHR-123 oxidation assay is the gold standard for making the diagnosis and it along with genetic testing can help predict the severity and prognosis in patients with CGD. Disease management focuses on prophylaxis with antibacterial, antifungal, and immunomodulatory medications, prompt identification and treatment of acute infections, and prevention of secondary granulomatous complications. While hematopoietic stem-cell transplantation is the only widely available curative treatment for patients with CGD, recent advances in gene therapy may provide a safer, more direct alternative.

Abstract
Chronic granulomatous disease (CGD) is a primary immunodeficiency of phagocyte function due to defective NADPH oxidase (phox). Compared with the common types of CYBB/gp91phox, NCF1/p47phox, and CYBA/p22phox deficiency, NCF4/p40phox deficiency is a mild and atypical form of CGD without invasive bacterial or fungal infections. It can be diagnosed using serum-opsonized E.coli as a stimulus in dihydrorhodamine (DHR) assay. Patients with CYBC1/Eros deficiency, a new and rare form of CGD, present as loss of respiratory burst and gp91phox expression in phagocytes. Neutrophils from patients with CGD are deficient in neutrophil extracellular traps (NETosis), autophagy, and apoptosis. The hyper-activation of NF-ĸB and inflammasome in CGD phagocytes also lead to long-lasting production of pro-inflammatory cytokines and inflammatory manifestations, such as granuloma formation and inflammatory bowel disease-like colitis. Patients with CGD and X-linked female carriers also have a higher incidence of autoimmune diseases. The implementation of antimicrobial, anti-fungal, and interferon-γ prophylaxis has greatly improved overall survival. Residual NADPH oxidase activity is significantly associated with disease severity and the chance of survival of the patient. New therapeutic approaches using immunomodulators for CGD-related inflammatory manifestations are under investigation, including pioglitazone, tamoxifen, and rapamycin. Hematopoietic stem cell transplantation (HSCT) is the curative treatment. Outcomes of HSCT have improved substantially over the last decade with overall survival more than 84-90%, but there are debates about designing optimal conditioning protocols using myeloablative or reduced-intensity regimens. The gene therapy for X-linked CGD using hematopoietic stem and progenitor cells transduced ex vivo by lentiviral vector encoding the human gp91phox gene demonstrated persistence of adequate oxidase-positive neutrophils in a small number of patients. Gene therapy using genome-editing technology such as CRISPR/Cas9 nucleases is a promising approach for patients with CGD in the future.

Abstract
A 3-years-old male golden retriever was presented for decreased activity (lethargy), anorexia, and titubation. Superficial lymph nodes were enlarged, and arrhythmia and tachycardia were auscultated. Fungal hyphae-like structures were detected in the biopsy samples from an enlarged lymph node and spleen. Nucleotide sequence of the internal transcribed spacer region of the fungi amplified by PCR was highly homologous to that of Inonotus pachyphloeus. The dog was treated with antifungal agents such as itraconazole, fluconazole, and voriconazole. Clinical signs resolved for 325 days but the dog died suddenly, possibly because of arrhythmia. Postmortem examination revealed the presence of a disseminated fungal infection. This report describes the case of canine systemic Inonotus sp. infection treated by an antifungal agent.

Abstract
Chronic granulomatous disease (CGD) is a heterogeneous condition due to defects in NADPH oxidase characterized by granuloma formation and increased susceptibility to invasive infections, in particular moulds. The use of broad-spectrum, mould-active antifungal prophylaxis has improved mortality. However rare resistant moulds have emerged as important pathogens. Diagnosis of these rare fungi requires molecular techniques, and treatment data are limited. Herein, we present a case of with disseminated Rasamsonia infection involving the heart.

Abstract
PURPOSE OF REVIEW Chronic granulomatous disease (CGD) is a primary immunodeficiency, with a defect of phagocytes in killing specific pathogens. CGD is characterized by severe recurrent bacterial and fungal infections and dysregulated inflammatory response. Since its first description as fatal disease about 60 years ago, a significant improvement in outcome has been achieved in the last 20 years. The purpose of this review is to framework recent advances in CGD immunopathogenesis, management of disease manifestation and cure of CGD patients. RECENT FINDINGS For years, CGD is a known cause of life-threatening infections and excessive inflammation. The cause and the management of inflammatory reactions, however, have not been clarified, and the range of clinical presentation is growing with corresponding novel therapeutic interventions. Recent work focuses on the best outcome of hematopoietic stem cell transplantation (HSCT) and gene therapy for the cure of CGD patients, more specifically, those with X-linked and p47 mutations. SUMMARY The genetics and phenotype of CGD is well characterized; however, the underlying mechanisms, the treatment of its inflammatory manifestations and the cure of CGD is under further investigation.

Abstract
The immune system is a complex system able to recognize a wide variety of host agents, through different biological processes. For example, controlled changes in the redox state are able to start different pathways in immune cells and are involved in the killing of microbes. The generation and release of ROS in the form of an “oxidative burst” represent the pivotal mechanism by which phagocytic cells are able to destroy pathogens. On the other hand, impaired oxidative balance is also implicated in the pathogenesis of inflammatory complications, which may affect the function of many body systems. NADPH oxidase (NOX) plays a pivotal role in the production of ROS, and the defect of its different subunits leads to the development of chronic granulomatous disease (CGD). The defect of the different NOX subunits in CGD affects different organs. In this context, this review will be focused on the description of the effect of NOX2 deficiency in different body systems. Moreover, we will also focus our attention on the novel insight in the pathogenesis of immunodeficiency and inflammation-related manifestations and on the protective role of NOX2 deficiency against the development of atherosclerosis.

Abstract
Chronic granulomatous disease (CGD) is a primary immunodeficiency caused by defects in any of the five subunits of the NADPH oxidase complex responsible for the respiratory burst in phagocytic leukocytes. Patients with CGD are at increased risk of life-threatening infections with catalase-positive bacteria and fungi and inflammatory complications such as CGD colitis. The implementation of routine antimicrobial prophylaxis and the advent of azole antifungals has considerably improved overall survival. Nevertheless, life expectancy remains decreased compared to the general population. Inflammatory complications are a significant contributor to morbidity in CGD, and they are often refractory to standard therapies. At present, hematopoietic stem cell transplantation (HCT) is the only curative treatment, and transplantation outcomes have improved over the last few decades with overall survival rates now > 90% in children less than 14 years of age. However, there remains debate as to the optimal conditioning regimen, and there is question as to how to manage adolescent and adult patients. The current evidence suggests that myeloablative conditioning results is more durable myeloid engraftment but with increased toxicity and high rates of graft-versus-host disease. In recent years, gene therapy has been proposed as an alternative to HCT for patients without an HLA-matched donor. However, results to date have not been encouraging. with negligible long-term engraftment of gene-corrected hematopoietic stem cells and reports of myelodysplastic syndrome due to insertional mutagenesis. Multicenter trials are currently underway in the United States and Europe using a SIN-lentiviral vector under the control of a myeloid-specific promoter, and, should the trials be successful, gene therapy may be a viable option for patients with CGD in the future.

Abstract
The global burden of fungal diseases has been increasing, as a result of the expanding number of susceptible individuals including people living with human immunodeficiency virus (HIV), hematopoietic stem cell or organ transplant recipients, patients with malignancies or immunological conditions receiving immunosuppressive treatment, premature neonates, and the elderly. Opportunistic fungal pathogens such as Aspergillus, Candida, Cryptococcus, Rhizopus, and Pneumocystis jiroveci are distributed worldwide and constitute the majority of invasive fungal infections (IFIs). Dimorphic fungi such as Histoplasma capsulatum, Coccidioides spp., Paracoccidioides spp., Blastomyces dermatiditis, Sporothrix schenckii, Talaromyces (Penicillium) marneffei, and Emmonsia spp. are geographically restricted to their respective habitats and cause endemic mycoses. Disseminated histoplasmosis, coccidioidomycosis, and T. marneffei infection are recognized as acquired immunodeficiency syndrome (AIDS)-defining conditions, while the rest also cause high rate of morbidities and mortalities in patients with HIV infection and other immunocompromised conditions. In the past decade, a growing number of monogenic immunodeficiency disorders causing increased susceptibility to fungal infections have been discovered. In particular, defects of the IL-12/IFN-γ pathway and T-helper 17-mediated response are associated with increased susceptibility to endemic mycoses. In this review, we put together the various forms of endemic mycoses on the map and take a journey around the world to examine how cellular and molecular defects of the immune system predispose to invasive endemic fungal infections, including primary immunodeficiencies, individuals with autoantibodies against interferon-γ, and those receiving biologic response modifiers. Though rare, these conditions provide importance insights to host defense mechanisms against endemic fungi, which can only be appreciated in unique climatic and geographical regions.
