ORTIZ-PEREZ, David Fernando et al. Severe Anemia Secondary to Trichuris trichiura Hyperinfestation: The Critical Role of Endoscopic Evaluation. Rev. colomb. Gastroenterol. [online]. 2026, vol.41, n.1, pp.83-88.  Epub 28-Abr-2026. ISSN 0120-9957.  https://doi.org/10.22516/25007440.1352.

Intestinal parasitic infection caused by Trichuris trichiura represents a significant public health concern in socioeconomically disadvantaged regions, where inadequate sanitation infrastructure and limited health education facilitate transmission. A case is presented involving a 35-year-old woman with severe hypochromic microcytic anemia (hemoglobin 6.2 g/dL), associated with gastrointestinal symptoms and signs of hemodynamic instability. Stool examination revealed T. trichiura ova, and colonoscopy demonstrated multiple filiform structures causing mucosal erosions throughout the colon, extending from the rectum to the distal ileum. Treatment consisted of albendazole 400 mg daily for three days, red blood cell transfusions, and iron supplementation, resulting in clinical improvement and hemodynamic stabilization. This case underscores the importance of considering T. trichiura infection in the differential diagnosis of anemia and highlights the relevance of multidisciplinary approaches integrating nutritional interventions, health education, and community-based control measures to interrupt transmission cycles and reduce associated morbidity.
