Hookworm infections are rare causes of acute gastrointestinal bleeding. We report a middle aged man with primary nephrotic syndrome and pulmonary embolism. During the treatment with steroids and anticoagulants, the patient presented acute massive hemorrhage of the gastrointestinal tract. The results of gastroscopy showed red worms in the duodenum. Colonoscopy and CT angiogram of abdomen were unremarkable. Capsule endoscopy revealed fresh blood and multiple hookworms in the jejunum and ileum. Hookworms caused the acute intestinal bleeding. The patient responded well to albendazole. Hematochezia was markedly ameliorated after eliminating the parasites. Hence, hookworm infection should be considered in the differential diagnosis of a patient with obscure gastrointestinal bleeding. Capsule endoscopy may offer a better means of diagnosis for intestinal hookworm infections.

To identify potential sources of hookworm infections in a Ghanaian community of endemicity that could be targeted to interrupt transmission, we tracked the movements of infected and noninfected persons to their most frequented locations. Fifty-nine participants (29 hookworm positives and 30 negatives) wore GPS trackers for 10 consecutive days. Their movement data were captured in real time and overlaid on a community grid map.

Background: Treatments for soil-transmitted helminthiases face challenges, especially in addressing Trichuris trichiura. Combination regimens, particularly of ivermectin and albendazole, are promising. We aimed to assess the safety, efficacy, and palatability of a combination tablet for the treatment of T trichiura, hookworm, and Strongyloides stercoralis infections among school-aged children in Ethiopia, Kenya, and Mozambique.

Hookworm infection represents a major global disease burden, in terms of both morbidity and economic impact, and there has been a resurgence of hookworms in developed nations where these parasites were once thought to be eradicated. Hookworms can infest humans or other mammals as their primary hosts depending on the species. The 2 most common species that seek human hosts-Necator americanus and Ancylostoma duodenale-enter the body through the epidermis, and hookworm infection may manifest as a pruritic and papular inflammatory reaction know as ground itch.

This study explores potential small animal models for the dog hookworm, , a parasitic nematode which has repeatedly exhibited the ability to develop resistance to a range of anthelmintics. Immunomodulated hamsters, gerbils, rats, and mice were infected with Despite varying degrees of immunosuppression, and in some cases, total adaptive immunodeficiency, no adult worms were recovered, and larval arrest (L3 stage) occurred in muscle tissue of mice and hamsters. This highlights the strict host specificity of and emphasizes the challenges of developing rodent models usable for anthelmintic testing with a strict specialist parasite.

Background: Recombinant Necator americanus Glutathione-S-Transferase-1 (Na-GST-1) formulated on Alhydrogel (Na-GST-1/Alhydrogel) is being developed to prevent anemia and other complications of N. americanus infection. Antibodies induced by vaccination with recombinant Na-GST-1 are hypothesized to interfere with the blood digestion pathway of adult hookworms in the host.
