Insights

A corticotropin treatment for infantile spasms in an infant with herpes simplex virus (HSV) encephalitis led to recurrent HSV reactivation. Concurrent acyclovir or avoiding corticotropin in HSV patients is recommended.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Pediatrics

Background:

  • Herpes simplex virus (HSV) encephalitis is a severe neurological infection in infants.
  • Acyclovir is the standard treatment for HSV encephalitis.
  • Infantile spasms are a type of epilepsy that can occur in infants.

Observation:

  • An infant with HSV encephalitis experienced severe brain damage despite acyclovir treatment.
  • The infant later developed infantile spasms and was treated with corticotropin.
  • Following corticotropin treatment, the infant showed signs of recurrent HSV encephalitis with new brain lesions.

Findings:

  • Corticotropin treatment may have caused immunosuppression, leading to HSV reactivation.
  • Recurrent HSV encephalitis occurred despite previous treatment and despite new brain lesions.

Implications:

  • Corticotropin may be relatively contraindicated in patients with a history of HSV infection.
  • Concurrent intravenous acyclovir administration should be considered during corticotropin treatment in such patients.
  • This case highlights the potential risks of immunosuppressive therapy in patients with a history of viral encephalitis.

Herpes

Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
Genital Herpes01:23

Genital Herpes

Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Chickenpox01:20

Chickenpox

Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
Botulism01:22

Botulism

Botulism is a life-threatening neuroparalytic condition caused by botulinum neurotoxin, which is produced by the bacterium Clostridium botulinum, a Gram-positive, spore-forming, obligate anaerobe.In adults, the toxin enters the body in different ways: in foodborne botulism, the preformed toxin is absorbed in the intestine. In wound botulism, spores grow in injured tissue and release the toxin into the blood. Infant botulism differs mechanistically from adult forms. In infants, botulism commonly...
