Amebiasis: Diagnosis and Treatment • Diagnosis: – Stool O+P unable to differentiate from E. dispar (nonpathogenic) – Stool antigen detection + serum antibody testing – Imaging • Single lesion in R lobe, nonspecific • Treatment – Asymptomatic colonization: paromomycin X 7 days – Colitis: metronidazole X 7‐10 days followed by luminal agent (paromomycin) – Liver Abscess: medications as above • If >5cm, not responding to medication in 5‐7d drain
Case 7 (continued) As you recognize that stool O+P cannot often differentiate E. dispar from E. histolytica, you send stool antigen testing for E. histolytica. All of your patients are negative. You astutely decide not to treat them for the carriage of these non‐pathogenic amebas and they continue to do well.
