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.
Abstract:
A prospective study of intestinal microsporidiosis in HIV-positive children was conducted at the Queen Sirikit National Institute of Child Health and Phramongkutklao Hospital, Bangkok, Thailand. Hospitalized HIV-positive children with and without diarrhea were enrolled in this study. Microsporidial spores identified by calcofluor fluorescent and gram-chromotrope stain were confirmed by electron microscopy. As well as Cryptosporidium parvum, Microsporidia was the most common protozoa found in the present study, each was 7.1%. Microsporidia was significantly more common in those who had diarrhea. Intestinal microsporidiosis was found in HIV-positive children with both acute and chronic diarrhea. This study emphasizes the importance of Microsporidia in HIV-infected children. Early detection of microsporidia could be of benefit for the patients, since the infection is treatable.
