Clinical Features, Diagnosis and Treatment of Amoebiasis

This topic focuses on the clinical management of amoebiasis, covering symptomatology, diagnostic approaches, and therapeutic strategies for Zambian tertiary health students. Learners will differentiate between asymptomatic cyst passage, intestinal amoebiasis (presenting with dysentery, abdominal pain, and tenesmus), and extra-intestinal amoebiasis (notably amoebic liver abscess with fever, hepatomegaly, and right upper quadrant pain). The module details laboratory diagnosis, emphasizing the microscopic identification of motile trophozoites with ingested red blood cells in fresh dysenteric stool and cysts in formed stool. Treatment protocols are explored, including the use of metronidazole for invasive disease and luminal agents like iodoquinol or paromomycin for eradicating cyst carriers. This comprehensive knowledge is essential for clinical decision-making, accurate laboratory reporting, and effective patient care in Zambian healthcare settings where amoebiasis remains a relevant public health concern.
