Insights

Microsporidia is a common intestinal parasite in HIV-positive children, especially those with diarrhea. Early detection and treatment of this microsporidiosis are crucial for patient benefit.

Area of Science:

  • Medical Microbiology
  • Infectious Diseases
  • Pediatrics

Background:

  • Human Immunodeficiency Virus (HIV) infection compromises the immune system, increasing susceptibility to opportunistic infections.
  • Intestinal parasitic infections are a significant cause of morbidity in immunocompromised individuals, particularly children.

Purpose of the Study:

  • To investigate the prevalence of intestinal microsporidiosis in hospitalized HIV-positive children in Bangkok, Thailand.
  • To determine the association between intestinal microsporidiosis and diarrhea in this population.

Main Methods:

  • A prospective study involving hospitalized HIV-positive children with and without diarrhea.
  • Identification of microsporidial spores using calcofluor fluorescent and gram-chromotrope stains.
  • Confirmation of Microsporidia by electron microscopy.

Main Results:

  • Microsporidia was identified as a common protozoan pathogen, with a prevalence of 7.1%, similar to Cryptosporidium parvum.
  • Microsporidiosis was significantly more prevalent in HIV-positive children experiencing diarrhea.
  • The infection was observed in children with both acute and chronic diarrhea.

Conclusions:

  • Microsporidia is an important intestinal pathogen in HIV-infected children.
  • Early diagnosis of intestinal microsporidiosis is beneficial due to its treatable nature.
  • Routine screening for Microsporidia should be considered in HIV-positive children presenting with gastrointestinal symptoms.

Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents

Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

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,...
Toxoplasmosis01:28

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
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...
