Prompt diagnosis of parasitic diarrhea in children is crucial. Stool examinations for Giardia and Cryptosporidium are key, with specific isolation protocols for Giardia and Cryptosporidium to prevent transmission.
Area of Science:
- Pediatric Gastroenterology
- Infectious Diseases
- Public Health
Background:
- Parasitic infections are a significant cause of diarrhea in pediatric populations.
- Accurate diagnosis and management are essential for public health and patient well-being.
- Common culprits in the US include Giardia and Cryptosporidium species.
Purpose of the Study:
- To outline diagnostic strategies for parasitic causes of pediatric diarrhea.
- To emphasize the importance of timely and accurate diagnosis in clinical practice.
- To provide guidance on treatment and transmission interruption for specific parasitic infections.
Main Methods:
- Stool examination for ova and parasites, performed three times on alternate days, is the gold standard for diagnosis.
- Serology and stool examination are recommended for amebiasis in travelers from endemic areas.
- Mucosal scrapings are indicated for suspected amebiasis in patients considered for corticosteroid therapy.
Main Results:
- Giardia and Cryptosporidium are the most prevalent parasitic causes of diarrhea in the United States.
- Amebiasis requires specific testing in at-risk populations, especially with bloody diarrhea.
- Immunocompromised children, including those with acquired immunodeficiency syndrome (AIDS), may have multiple parasitic infections.
Conclusions:
- Vigorous diagnostic pursuit in appropriate clinical settings is vital for pediatric parasitic diarrhea.
- Interrupting transmission, particularly in daycare settings, is critical for Giardia and Cryptosporidium.
- Aggressive diagnostic approaches are necessary for immunocompromised children with diarrhea.
Abstract:
Parasitic causes of diarrhea are common in pediatric patients and have important public health implications. Therefore, diagnosis should be pursued vigorously in the appropriate clinical setting. Giardia and Cryptosporidium infections are the most common causes of disease in the United States, and stool examination for ova and parasites is the best way to make the diagnosis. This should be performed three times, on alternate days, in order to rule out parasitic disease with confidence. In treatment of Giardia, it is important to interrupt transmission, particularly in the day-care setting. Because of the potential for major outbreaks, patients with cryptosporidiosis should be kept out of day care until their symptoms resolve. Although amebiasis is not a common problem in the United States, all patients with bloody diarrhea who have traveled to, or are from, endemic areas should be tested for amebiasis by serology and stool examination. If patients with suspected inflammatory bowel disease are being considered for therapy with corticosteroids, mucosal scrapings of colonic lesions should be examined for amoebae, because corticosteroid therapy can lead to more invasive amoebic disease. Acquired immunodeficiency syndrome patients with diarrhea can be infected with a number of pathogens and a specific diagnosis should be pursued aggressively. These patients are often infected with one or more of the parasites described in this article. The approach to diarrhea in these children is described in a separate article of this issue (Deveikis A. 'Gastrointestinal Disease in Immunocompromised Children," pages 562-569).
