Insights

Cytomegalovirus and human herpesvirus 6B (HHV-6B) are common causes of fever in children with cancer. These viruses should be considered in the differential diagnosis for febrile illnesses in this population.

Area of Science:

  • Infectious Diseases
  • Pediatric Oncology
  • Virology

Background:

  • Febrile illnesses in pediatric oncology patients can have various etiologies.
  • Beta-herpesviruses, including cytomegalovirus (CMV) and human herpesvirus 6B (HHV-6B), are known opportunistic pathogens.

Purpose of the Study:

  • To investigate the prevalence of beta-herpesviruses in febrile pediatric oncology patients.
  • To compare the incidence of these viral infections with a reference group of febrile pediatric solid-organ transplant recipients.

Main Methods:

  • A cross-sectional study was conducted.
  • Polymerase chain reaction (PCR) was used to detect viral DNA.
  • Patients were categorized into two groups: pediatric oncology patients and pediatric solid-organ transplant recipients.

Main Results:

  • Cytomegalovirus (CMV) was detected in 3.3% of cancer patients and 33% of transplant recipients.
  • Human herpesvirus 6B (HHV-6B) DNAemia was found in 13% of cancer patients and 33% of transplant recipients.
  • HHV-6B was more prevalent within 6 months of initiating immunosuppression in cancer patients (p=0.050).
  • HHV-6A and HHV-7 were not detected.

Conclusions:

  • CMV and HHV-6B are significant causes of febrile disease in pediatric oncology patients.
  • These viruses should be included in the differential diagnosis for fever in immunocompromised children.
  • Early detection and consideration of these viral infections are crucial for appropriate management.

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...

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...
Herpes01:28

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...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...
