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.

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...

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 Microsporidia01:28

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...

Drugs for Treatment of Diarrhea-Predominant IBS

Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

American Trypanosomiasis

Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
