“…1. explained how chronic and persistent bleeding (hemorrhage) right at the site of its attachment made possible and resulted in an iron-deficiency anemia that happened chronically [10], accompanied with serum and gastrointestinal protein loss [11], and even induced unnoticed minimal intestinal inflammation that somehow promotes their own survival, by creating certain local immunoregulatory milieu thanks to their excretory/secretory products [12], but on the other hand, paradoxically also benefits the host by protecting against the onset of many inflammatory diseases [13].…”

Aims: To differentiate morphologically and functionality of chitin bodies belong to Necator americanus (old world hook worm) vs. 2 pair of teeth belong to Ancylostoma duodenale (new world hook worm) Discussion: Anemia due to hookworms caused by persistent blood loss. Those micro-bleeding occurs due to the attachment to the villi of the host’s small intestine in order to facilitate feed on their host’s blood. Hookworms use their two pairs of teeth (A. duodenale) or cutting plates called chitin bodies (N. americanus) to fasten their attachment onto the mucosa and submucosa, where at the same time they secrete a series of biochemically active polypeptides that prevent blood from clotting and supress the host inflammatory response. Differences in the shape of teeth or similar apparatus in the two species of hookworms that infect humans play a role in the occurrence of persistent minor bleeding that causes anemia and this also depend on the number of hookworms invaded the host. Conclusion: chitin bodies of N. americanus causes less bleeding than two pairs of teeth belongs to A. duodenale

Las infecciones por uncinarias pueden producir anemia por deficiencia de hierro y en raras ocasiones producen anemia grave que amenaza la vida. Se presenta el caso de un paciente masculino de 38 años que consultó por presentar deposiciones melénicas, astenia, adinamia, vértigo, visión borrosa, dolor precordial y disnea de pequeños esfuerzos. En la evaluación se consideró que el paciente presentaba anemia grave por deficiencia de hierro con inestabilidad hemodinámica; la endoscopia de vías digestivas altas y la colonoscopia fueron normales. La cápsula endoscópica reveló múltiples uncinarias en el yeyuno que fueron la causa del sangrado intestinal crónico. El paciente fue tratado con albendazol por 5 días, y repitió una dosis a los 21 días. El presente caso evidencia que las uncinarias deben ser consideradas en el diagnóstico diferencial de pacientes con hemorragia digestiva oscura procedentes de zonas rurales.
