Insights

Children with HIV-1 infection experience more severe diarrhea, often with dehydration and fatality. Maternal AIDS and malnutrition also contribute to increased diarrhea risk in infants.

Area of Science:

  • Pediatric Infectious Diseases
  • Global Health
  • Virology

Background:

  • Diarrhea and weight loss are common in pediatric Human Immunodeficiency Virus type 1 (HIV-1) infection, especially in developing nations.
  • Understanding the impact of HIV-1 on diarrheal disease in infants is crucial for public health interventions.

Purpose of the Study:

  • To investigate the characteristics and risk factors of diarrheal episodes in infants with perinatal HIV-1 infection.
  • To compare the severity and outcomes of diarrhea in HIV-1-infected versus uninfected children.

Main Methods:

  • Prospective longitudinal study of 559 children (10-15 months) in Kinshasa, Zaire.
  • Analysis of diarrheal episodes, clinical presentation, dehydration severity, and causative pathogens.
  • Logistic regression to identify associations between diarrhea and HIV-1 status, malnutrition, and maternal health.

Main Results:

  • HIV-1-infected children had more frequent, severe, persistent, and fatal diarrhea episodes.
  • Enteroadherence factor-positive Escherichia coli was associated with HIV-1 infection (P=0.04).
  • Diarrhea was significantly linked to child's HIV-1 status, maternal malnutrition, and maternal Acquired Immunodeficiency Syndrome (AIDS).

Conclusions:

  • Diarrhea in perinatally HIV-1-infected children in Zaire is more severe than in uninfected children.
  • Maternal malnutrition and advanced maternal disease are significant risk factors for severe diarrhea in these infants.
  • Findings highlight the need for integrated care addressing both child's HIV status and maternal health.

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...
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
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...
Cryptococcal Meningitis01:27

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,...
Giardiasis01:12

Giardiasis

Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
