Central Nervous System Fungal Infections in Children With Leukemia and Undergoing Hematopoietic Stem Cell Transplantation: A Retrospective Multicenter Study. J Pediatr Hematol Oncol 2022; 44:e1039-e1045.

Abstract
BACKGROUND Central nervous system fungal infections (CNSFI) are seen in patients with hematologic malignancies and have high morbidity and mortality. Because of their rarity, there is limited data on CNSFI in children with no established treatment protocols or guidelines. MATERIALS AND METHODS In this multicenter retrospective study, 51 pediatric patients with leukemia, 6 of whom had undergone bone marrow transplantation, with proven or probable CNSFI were evaluated. Fungal infections were defined as proven or probable based on European Organisation for Research and Treatment of Cancer criteria. Proven CNSFI was diagnosed by appropriate central nervous system (CNS) imaging or tissue sample findings in combination with positive microbiological results of cerebrospinal fluid. A positive culture, microscopic evidence of hyphae, a positive result of the galactomannan assays are defined as positive microbiological evidence. Probable CNSFI was defined as appropriate CNS imaging findings together with proven or probable invasive fungal infections at another focus without CNS when there is no other explanatory condition. Data was collected by using the questionnaire form (Supplemental Digital Content 1, http://links.lww.com/JPHO/A541 ). RESULTS Seventeen patients had proven, 34 patients had probable CNSFI. Headaches and seizures were the most common clinical findings. The median time between the onset of fever and diagnosis was 5 days. The most common fungal agent identified was Aspergillus . Sixteen patients received single-agent, 35 received combination antifungal therapy. Surgery was performed in 23 patients. Twenty-two patients (43%) died, 29 of the CNSFI episodes recovered with a 20% neurological sequelae. CONCLUSION CNSFIs should be considered in the differential diagnosis in patients with leukemia and refractory/recurrent fever, headache, neurologicalocular symptoms, and a radiologic-serological evaluation should be performed immediately. Early diagnosis and prompt management, both medical and surgical, are essential for improving clinical outcomes.

Abstract
Fungal infections of the central nervous system are fatal and rare clinical
entities observable in immunosuppressed patients from varying causes. They carry
higher risks of morbidities and mortality as compared to viral, bacterial or
parasitic central nervous system infections. This study describes
clinicopathological description of the central nervous system fungal infections
with antemortem diagnostic challenges. This is a 9-year retrospective study of
six cases composed of three females and three males with a mean age of
29.3 years. All six decedents presented with signs of meningeal irritation. They
all suffered from immunodeficiency of varying causes. The gross and microscopic
features revealed cryptococcosis, candidiasis and mucormycosis as the cause of
the central nervous system infection. Early diagnosis and appropriate medical
treatment are of paramount importance in improving the overall survival of
patients with central nervous system mycosis. A few autopsy cases with fungal
infection of the central nervous system have been described; therefore, more
autopsies studies are needed to re-enforce on the existing epidemiology of these
fatal infections. Moreover, this will assist in further elucidating the varying
gross features and tissue reaction patterns associated with them.

Abstract
Although uncommon in children, fungal infections of the central nervous system can be devastating and difficult to treat. A better understanding of basic mycologic, immunologic, and pharmacologic processes has led to important advances in the diagnosis and management of these diseases, but their mortality rates remain unacceptably high. In this focused review, we examine the epidemiology and clinical features of the most common fungal pathogens of the central nervous system in children and explore recent advances in diagnosis and antifungal therapy.

Abstract
BACKGROUND There are few published studies on the spectrum and outcome of central nervous system (CNS) infection in the neurology intensive care unit (NICU). We report the spectrum of CNS infections in the NICU and the predictors of outcome. METHODS During 2011 to 2012, 235 critically ill neurological patients were admitted to a 12-bed NICU in a tertiary-care teaching hospital in Lucknow, northern India; 76 (32.3%) of them had CNS infections and were included in the present study. The patients' demographic and clinical details were noted, together with the underlying aetiology, Glasgow Coma Scale (GCS) score, Acute Physiology and Chronic Health Evaluation (APACHE II) score, systemic inflammatory response syndrome (SIRS) and complications during mechanical ventilation. Deaths were recorded, and 3-month functional outcome in the surviving patients assessed by the modified Rankin Scale (mRS). RESULTS The median age of the patients was 37.5 (4-75) years and 31 were females; 36/76 (47%) patients had tuberculous meningitis, 28/76 (37%) viral encephalitis, 8/76 (11%) pyogenic meningitis and 4/76 (5%) fungal meningitis. Seven of these patients had AIDS. The median duration of mechanical ventilation was 8 (1-121) days and 39/76 patients (51.3%) died. Duration of hospital stay (OR 1.2, 95% CI 1.05-1.37, p=0.006) and duration of mechanical ventilation (OR 0.81, 95% CI 0.68-0.95, p=0.01) were independent predictors of death. At 3-month follow-up, 23/37 patients (62%) had recovered well, 10/37 (27%) were severely disabled and 4/37 (11%) had died. CONCLUSION Of patients admitted to the NICU during the study period, one-third had a CNS infection. Half of those with a CNS infection survived, and predictors of death were prolonged mechanical ventilation and prolonged hospital stay.

Abstract
An invasive fungal infection is a rare disease that can occur in otherwise healthy individuals. Fungi themselves are universal, and they are overall harmless organisms that cause at most a self-limiting disease in the general population. Immunocompromised individuals, whether iatrogenically, genetically, or acquired, present a group who are especially susceptible to a life-threatening disease from a normally innocuous pathogen. Fungi are normally inhaled and are cleared by pulmonary defense mechanisms in immunocompetent hosts. Invasion begins when these mechanisms fail in depressed immunity. Through bypassing of the pulmonary immune system, fungi can spread hematogenously. Fungal infections of the central nervous system are the most common extrapulmonary manifestation after fungal inhalation. Other risk factors of fungemia include prolonged indwelling catheters, maxillofacial infections, uncontrolled diabetes mellitus, systemic antibiotics, implanted neurosurgical devices, and intravenous drug abuse. Thus, other than direct inoculation via surgical complications or open trauma, central nervous system fungal infections are almost never primary.

Abstract
Neurologists may be confronted with patients who present with inflammatory brain lesions where the diagnosis cannot be made through history and physical examination alone. Molecular testing for bacterial infections, tuberculosis, and fungal infections may aid in the diagnosis. Since the treatments for these disorders are different and delays can result in permanent neurologic disability and death, rapid and accurate diagnoses are critical. This review provides the neurologist with testing options and recommends ways to enhance sensitivity and specificity.
