A novel experience with remission of severe, recalcitrant fontan-associated protein-losing enteropathy: a case report.

Protein-losing enteropathy associated with failing Fontan circulation remains a significant challenge in long-term, single-ventricle circulation management. Evidence is very limited regarding medical therapies associated with a reduction in disease severity and morbidity outside of cardiac transplantation. We report a novel experience with remission of recalcitrant protein-losing enteropathy after treatment of Cryptosporidium gastroenteritis with a combination of antimicrobials including nitazoxanide, paromomycin, and azithromycin.
