Central Nervous System Histoplasmosis After Acute COVID-19 in An Adolescent
Abstract:
Central nervous system histoplasmosis is a serious complication of a common endemic mycosis, but it is rare in immunocompetent hosts. SARS-CoV-2 has introduced significant challenges into the healthcare setting with overlapping clinical presentations that may delay the diagnosis of alternative conditions. Additionally, it may lead to immune dysregulation and increase the risk for secondary infections, including invasive fungal diseases. Limited reports have described disseminated histoplasmosis in adults associated with COVID-19, but none have described central nervous system infection or complications in pediatric patients. We report a case of disseminated histoplasmosis involving the central nervous system in a previously healthy 13-year-old male with SARS-CoV-2 infection. An extensive immunological evaluation did not identify an underlying immunodeficiency. We highlight the potential of COVID-19 immune dys-regulation to contribute to the development or progression of invasive fungal disease. [Pediatr Ann. 2024;53(8):e305-e309.].
Insights
Central nervous system histoplasmosis is a rare but serious fungal infection. This case highlights a previously healthy child with COVID-19 who developed this severe condition, suggesting a link between SARS-CoV-2 and invasive fungal disease.
Area of Science:
- Infectious Diseases
- Mycology
- Pediatric Neurology
Background:
- Central nervous system (CNS) histoplasmosis is a severe complication of Histoplasma capsulatum infection, typically seen in immunocompromised individuals.
- The COVID-19 pandemic has presented diagnostic challenges due to overlapping symptoms and potential immune dysregulation, increasing the risk of secondary infections.
- While disseminated histoplasmosis has been reported in adults with COVID-19, CNS involvement in pediatric cases remains undescribed.
Observation:
- A previously healthy 13-year-old male presented with disseminated histoplasmosis involving the CNS.
- The patient had a concurrent SARS-CoV-2 infection.
- Comprehensive immunological assessment revealed no underlying immunodeficiency.
Findings:
- This case represents the first reported instance of central nervous system histoplasmosis in a pediatric patient with COVID-19.
- The absence of a known immunodeficiency suggests that SARS-CoV-2-induced immune dysregulation may play a role in the pathogenesis of invasive fungal infections.
- Disseminated histoplasmosis can occur in immunocompetent hosts during SARS-CoV-2 infection.
Implications:
- Highlights the potential for COVID-19 to precipitate invasive fungal infections, even in previously healthy children.
- Underscores the importance of considering opportunistic infections in pediatric patients with SARS-CoV-2, particularly those with neurological symptoms.
- Suggests a need for further research into the immunomodulatory effects of SARS-CoV-2 and their impact on susceptibility to fungal pathogens.
