Intestinal nematode infection

Last edited: 4/16/2026

Overview

Intestinal nematode infections, commonly known as helminth infections, involve parasitic worms residing in the gastrointestinal tract, often leading to significant morbidity, particularly anemia, especially in resource-limited settings 1.

Diagnosis

  • Stool microscopy for eggs or larvae remains the gold standard 1.
  • Hemoglobin levels to assess for anemia 1.
  • Clinical symptoms such as abdominal pain, diarrhea, and weight loss can guide suspicion 1.

    • Management

  • First-line treatment: Deworming with anthelmintic drugs (specific drugs and doses not detailed in abstract) 1.
  • Adjunctive therapy: Iron supplementation to address anemia concurrently 1.

    • Special Populations

  • Pregnancy: Deworming and iron supplementation are recommended but require careful monitoring 1.
  • Pediatrics: Early intervention with deworming and iron is crucial for growth and development 1.

    • Key Recommendations

  • Implement routine deworming programs with anthelmintic drugs in endemic areas to reduce morbidity (Evidence: Strong 1).
  • Concurrent iron supplementation should be provided to patients with evidence of anemia to combat nutritional deficiencies (Evidence: Strong 1).
  • Tailor management strategies in pregnant women and children to ensure safety and efficacy, emphasizing regular monitoring (Evidence: Moderate 1).
