Cerebral aspergillosis

Mucormycosis in human immunodeficiency virus (HIV) infection is uncommon; notably, many cases have additional predisposing factors. Whether mucormycosis differs in HIV-affected individuals with and without additional risk factors (e.g., neutropenia, diabetes mellitus, and transplantation) remains unclear. In this systematic review, we identified 94 cases of HIV and mucormycosis classifiable into three groups: (1) HIV with additional risk factors (n = 50), (2) intravenous drug users (IVDU, n = 24), and (3) no other risk factor (n = 19) for mucormycosis...

PURPOSE: Macrophage activation syndrome (MAS) is a rare illness, especially in critically ill adults. The diagnosis of MAS is challenging, requiring the expertise of multiple specialists, and treatments for MAS can be associated with catastrophic complications. CLINICAL FEATURES: We describe the case of a 31-yr-old Vietnamese student who was diagnosed with cutaneous systemic lupus erythematosus (SLE) in November 2020 and was initiated on treatment with low-dose corticosteroids and hydroxychloroquine as an outpatient...

PURPOSE: Invasive cerebral aspergillosis (ICA) is a rare but fatal infection affecting neutropenic immunocompromised patients. Recently cases have been reported in non-neutropenic settings also. We hereby present a series of ICA cases in non-neutropenic patients diagnosed at our tertiary care centre in Western India between March to October 2021. METHODS: All patients with clinico-radiological suspicion of CNS infections were analysed. Data regarding Clinico-radiological features, diagnosis, treatment and outcome were collected...

We report the case of a 32-year-old man receiving chemotherapeutics for an acute B-lymphoblastic leukemia who developed proven cerebral and pulmonary aspergillosis with Aspergillus flavus . Because of progressive fungal disease with neurological deterioration despite adequate systemic antifungal therapy and surgical debridement, intracerebral administration of liposomal amphotericin B was initiated at 5 mg twice weekly. This led to improvement of the cerebral infection. Surgical debridement of a pleural Aspergillus empyema was necessary, and pleural trough level of isavuconazole was found to be subtherapeutic despite adequate blood trough levels, which led us to increase the dose of isavuconazole...

Over 95,000 renal transplantation procedures were completed in 2021. Invasive aspergillosis (IA) affects about 1 in 250 to 1 in 43 renal transplant recipients. About 50% of cases occur in the first 6 months after transplantation; the median time of onset is nearly 3 years. Major risk factors for IA include old age, diabetes mellitus (especially if prior diabetic nephropathy), delayed graft function, acute graft rejection, chronic obstructive pulmonary disease, cytomegalovirus disease, and neutropenia. Hospital construction, demolition activities, and residential refurbishments also increase the risk...

BACKGROUND: The authors present a case of a 67-year-old woman with primary biliary cirrhosis (Child-Pugh class B) who was treated with isavuconazole for invasive pulmonary and cerebral aspergillosis. Isavuconazole treatment was initiated with the standard maintenance dose of 200 mg daily. Therapeutic drug monitoring (TDM) was performed to target trough concentrations within the desired range of 1.0-5.13 mg/L. METHODS: Real-time TDM and pharmacokinetic analyses were used to determine the dose adjustments...

Mucormycosis (MCR) is a rare but aggressive fungal disease. Rhino-orbito-cerebral mucormycosis is the most common clinical form of MCR infection, and sinonasal inoculation is the primary site of infection. The morbidity and mortality rates associated with MCR remain high. In this case report, we describe the successful use of amphotericin B in a 40-year-old male with hemorrhagic fever with renal syndrome (HFRS) complicated by rhinomucormycosis. This case report provides evidence for the successful treatment of HFRS...

Aspergillus is a fungal genus found worldwide, which causes infection most commonly in the respiratory system and in other systems, including the central nervous system. Fungal species, such as Aspergillus fumigatus or flavus, are more common in immunocompromised patient populations, such as those taking immunosuppressants post-transplantation, those on long-term corticosteroids, or those with immunodeficiencies such as AIDS. In this paper, we describe a rare case of aspergillosis that occurred due to a history of taking corticosteroids to treat arthritis pain in a patient with type 2 diabetes...

Invasive aspergillosis is a major cause of infectious disease in immunocompromised patients; however, cardiac involvement in pulmonary aspergillosis is not well-known. Two paediatric patients undergoing chemotherapy were diagnosed with cardiac aspergilloma, accompanied by pulmonary aspergillosis. In both patients, antibiotic and antifungal treatments were initiated immediately after the pneumonia was diagnosed; however, both died of multiple cerebral thromboembolisms.

Acute invasive fungal rhinosinusitis is a rare infection primarily affecting patients with co-morbidities like immunosuppression and poorly controlled diabetes. Mucormycosis is increasingly being reported in patients with SARS-CoV-2 (COVID-19). However, reports of coinfection of aspergillosis and mucormycosis involving nose, paranasal sinuses, orbit, and brain are rare in literature. We aimed to evaluate the patient demographics, clinical presentation, and management of cases presenting with mixed infection...

Exposure of immunosuppressed individuals to the opportunistic fungal pathogen Aspergillus fumigatus may result in invasive pulmonary aspergillosis (IPA), which can lead to the development of cerebral aspergillosis (CA), a highly lethal infection localized in the central nervous system (CNS). There are no experimental models of CA that effectively mimic human disease, resulting in a considerable knowledge gap regarding mechanisms of neurological pathogenicity and neuroimmune responses during infection. In this report, immunosuppressed mice (via acute, high-dose corticosteroid administration) challenged with A...

There has been a noted increase in the incidence of intracranial aspergillosis; this is often attributed to the wider use of antibiotics, corticosteroids, and immunosuppressants. Fungal cerebral aneurysms due to aspergillosis after neurosurgery remain extremely rare; in fact, only seven cases have been reported in the literature. In this study, we present a patient with an Aspergillus aneurysm that elicited subarachnoid hemorrhage after endoscopic endonasal surgery (EES) for craniopharyngioma. A 70-year-old woman with recurrent craniopharyngioma and steroid treatment underwent uneventful EES...

Radiological presentation of central nervous system (CNS) aspergillosis is variable and depends on the immune status of the patients. Typical features of meningoencephalitis, infarction, abscess, and mycotic aneurysms commonly occur in immunocompromised patients. A rare mass-like or tumoral form of cerebral aspergillosis has been described mostly in immunocompetent patients which results in a diagnostic dilemma, thus potentially causing a delay in the management. We present a case of a large CNS aspergilloma mimicking an infiltrative callosal neoplasm in a young immunocompetent patient...

Disseminated disease following invasive pulmonary aspergillosis (IPA) remains a significant contributor to mortality amongst patients with hematologic malignancies (HMs). At the highest risk of mortality are those with disseminated disease to the central nervous system, known as cerebral aspergillosis (CA). However, little is known about the risk factors contributing to disease amongst HM patients. A systematic review using PRISMA guidelines was undertaken to define HM patient subgroups, preventative measures, therapeutic interventions, and outcomes of patients with disseminated CA following IPA...

OBJECTIVE: Pediatric invasive fungal rhinosinusitis (IFS) is a devastating infection that manifests almost exclusively in immunocompromised children. The goal of this work was to determine which clinical features carry prognostic value for survival. METHODS: A retrospective review of children with a histopathological diagnosis of IFS was performed at an academic tertiary care institution from 1990 to 2021. Clinical variables were collected to generate survival and life-table estimators at 6-months and 1-year...

Introduction and importance: Although some immunocompetent patients have developed invasive aspergillosis, the vast majority of cases are seen in immunocompromised patients. COVID-19 infection has been proposed to cause immune dysfunction or suppression, which predisposes patients to fungal co-infections such as mucormycosis and aspergillosis. Case presentation: A 58-year-old woman was admitted to the hospital with confusion, dysarthria, and loss of consciousness...

Invasive fungal diseases (IFD) still cause substantial morbidity and mortality, and new therapeutic approaches are urgently needed. Recent data suggest a benefit of checkpoint inhibitors (ICI). We report the case of a diabetic patient with refractory IFD following a SARSCoV-2 infection treated by ICI and interferon-gamma associated with antifungal treatment.
