Sexual history reveals that he has sex with men and women and uses protection most of the time. He is febrile with all other vital signs within normal limits. Physical exam demonstrates tenderness to palpation of the right upper quadrant. Subsequent ultrasound shows a uniform cyst in the liver. In addition to draining the potential abscess and sending it for culture, appropriate medical therapy would involve which of the following?? A: Amphotericin, B: Nifurtimox, C: Supportive therapy, D: Sulfadiazine and pyrimethamine, E: Metronidazole and iodoquinol,  <response>: This is a clinical vignette about a 27-year-old man with bloody diarrhea, abdominal pain, fever, and liver abscess. Key details in the history include:- Previously healthy - Has sex with men and women, uses protection inconsistently- Physical exam shows RUQ tenderness- Ultrasound shows liver abscessThe question asks about appropriate medical therapy for this patient after draining the abscess and sending it for culture. Based on the history of inconsistent condom use and the liver abscess, the leading diagnosis is amebic liver abscess caused by Entamoeba histolytica. This is treated with metronidazole to kill the parasite, plus a luminal agent like iodoquinol to eradicate any intestinal parasites.Amphotericin is used for fungal infections rather than parasites. Nifurtimox is used for Chagas disease. Supportive therapy alone would not treat the underlying infection. Sulfadiazine and pyrimethamine are used for toxoplasmosis.E: Metronidazole and iodoquinol
