Insights

Cytomegalovirus (CMV) disease is common in Chilean children with human immunodeficiency virus type 1 (HIV-1), causing significant mortality. Prompt diagnosis and ganciclovir treatment are crucial for better outcomes in these vulnerable patients.

Area of Science:

  • Pediatric Infectious Diseases
  • Virology
  • Immunocompromised Hosts

Context:

  • Cytomegalovirus (CMV) is a significant opportunistic infection in children with human immunodeficiency virus type 1 (HIV-1).
  • CMV infection contributes to substantial morbidity and mortality in this population.
  • Chilean HIV-1 infected children represent a cohort with potential vulnerability to CMV disease.

Purpose:

  • To investigate the frequency of Cytomegalovirus (CMV) disease in a prospective cohort of HIV-1 infected children in Chile.
  • To assess the clinical impact and outcomes of CMV disease in this specific pediatric population.
  • To evaluate diagnostic methods and treatment efficacy for CMV disease in HIV-1 infected children.

Summary:

  • Cytomegalovirus (CMV) disease was diagnosed in 12.6% (28/222) of HIV-1 infected children.
  • The majority of cases were severe (CDC Category C and Stage 3), with lung disease being the most frequent manifestation.
  • Shell vial assay was the primary diagnostic tool; all patients received intravenous ganciclovir, with two deaths during the CMV episode.

Impact:

  • CMV disease is a frequent and potentially fatal complication in HIV-1 infected Chilean children.
  • Early detection and prompt treatment with ganciclovir are critical for improving survival rates.
  • This study highlights the importance of vigilant CMV monitoring in pediatric HIV cohorts.

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...
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...
Respiratory Syncytial Virus Disease01:29

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...

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
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,...
