Clinical Presentation & Protocol
Patient Usually Complains Of
Patient presents with chronic gastrointestinal distress, including intermittent abdominal pain, nausea, and diarrhea. History is significant for potential fecal-oral exposure. Symptoms are consistent with Hymenolepis nana autoinfection, characterized by persistent or worsening symptoms due to the internal life cycle of the parasite. No history of recent travel to endemic areas, suggesting possible household or institutional transmission.
Clinical Examination Findings
General physical examination reveals mild epigastric tenderness on deep palpation. No evidence of rebound tenderness or guarding. Bowel sounds are hyperactive. Patient is afebrile; mucous membranes are moist. Stool examination (O&P) confirms presence of H. nana eggs. Peripheral blood smear may show mild eosinophilia.
Treatment Protocol
Initiate Praziquantel 25 mg/kg as a single oral dose. Due to the autoinfection cycle of H. nana, a repeat dose is required after 10-14 days to eliminate newly matured worms. Monitor for resolution of gastrointestinal symptoms. Advise strict hand hygiene and sanitation to prevent reinfection.
