Not your typical hookworm infection—a case report from the Peruvian Amazon and review of the literature

Human hookworm infection is caused by the nematodes <i>Necator americanus</i>, <i>Ancylostoma duodenale</i>, and <i>Ancylostoma ceylanicum</i>. Iron deficiency anemia is the hallmark of chronic, moderate-to-heavy-intensity infections, promoting a vicious poverty cycle. Overt severe and acute life-threatening lower gastrointestinal hemorrhage is an extremely rare manifestation of hookworm infection, as well as finding multiple nematodes attached to the colonic mucosae. This rare hookworm presentation with hematochezia from the colon in a patient living with human immunodeficiency virus highlights the importance of physicians' awareness of this neglected tropical disease responsible for high morbidity and burden in healthcare systems of endemic regions.

Abstract

Human hookworm infection is caused by the nematodes <i>Necator americanus</i>, <i>Ancylostoma duodenale</i>, and <i>Ancylostoma ceylanicum</i>. Iron deficiency anemia is the hallmark of chronic, moderate-to-heavy-intensity infections, promoting a vicious poverty cycle. Overt severe and acute life-threatening lower gastrointestinal hemorrhage is an extremely rare manifestation of hookworm infection, as well as finding multiple nematodes attached to the colonic mucosae. This rare hookworm presentation with hematochezia from the colon in a patient living with human immunodeficiency virus highlights the importance of physicians' awareness of this neglected tropical disease responsible for high morbidity and burden in healthcare systems of endemic regions.
