Insights
Emerging intestinal coccidia, Cryptosporidium and Cyclospora cayetanensis, were significantly associated with childhood diarrhea in Havana. Infections correlated with prolonged diarrhea and abdominal pain, indicating their pathogenic role.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Pediatrics
Background:
- Intestinal parasitic infections are a significant cause of childhood morbidity globally.
- The role of emerging coccidia, such as Cryptosporidium and Cyclospora, in pediatric diarrhea requires further investigation in diverse geographical settings.
Purpose of the Study:
- To investigate the association between specific intestinal parasite species and diarrhea in hospitalized children in Havana, Cuba.
- To determine the clinical manifestations associated with infections by Cryptosporidium and Cyclospora cayetanensis in pediatric patients.
Main Methods:
- A case-control study was conducted involving 401 pediatric patients (113 with diarrhea, 288 without).
- Stool samples were analyzed using three parasitological techniques to identify intestinal parasites.
- Statistical analysis was performed to compare parasite frequencies and clinical symptoms between groups.
Main Results:
- Cryptosporidium spp. and Cyclospora cayetanensis were exclusively found in children with diarrhea (P < 0.01).
- Infections with Cryptosporidium were linked to prolonged diarrhea duration (P < 0.01).
- Cyclospora infections were associated with increased incidence of abdominal cramps/pain and acute diarrhea (P < 0.01).
Conclusions:
- Emerging intestinal coccidia, Cryptosporidium and Cyclospora cayetanensis, are significant pathogens in pediatric diarrhea in this Cuban population.
- These findings highlight the importance of identifying these specific parasites in children presenting with diarrheal illness.
- Further research on the epidemiology and clinical impact of coccidial infections in children is warranted.
Abstract:
From May to August 1999, we evaluated 401 patients from a pediatric hospital of Havana City. One group was composed of 113 patients with diarrhea admitted to the Gastroenterology ward and a second consisted of 288 patients without diarrhea, admitted for other reasons, and hospitalized within the same time period. Three stool samples were collected from each child and were examined using three parasitological techniques. When we compared the frequency of parasite species between both groups, we found Cryptosporidium spp. and Cyclospora cayetanensis, only in the group of children with diarrhea (P < 0.01). However, no significant differences were found in the occurrence of the other intestinal parasites (P > 0.05). In addition, in those children infected with Cryptosporidium, the diarrhea had a more prolonged duration (P < 0.01), while those infected with Cyclospora, the abdominal cramps or pain, and acute diarrhea were more frequently detected (P < 0.01). Our results showed that emerging intestinal coccidia are pathogens strongly associated in this group of children with diarrhea.
