BMC Infect Dis 2020 Jul 2;20(1):470. Epub 2020 Jul 2.

Department of Hematology and Rheumatology, Kindai University School of Medicine, 377-2 Oonohigashi, Osaka-Sayama, Osaka, 589-0014, Japan.

Background: Strongyloidiasis is a gastrointestinal parasitic infection caused by percutaneous infection with Strongyloides stercoralis. Digestive symptoms such as diarrhea and abdominal pain are the main manifestation, but serious infections such as septicemia, purulent meningitis, and bacterial pneumonia may occur in individuals harboring human T-lymphotropic virus type 1 (HTLV-1) or who are immunocompromised. Although coinfection with Strongyloides stercoralis and HTLV-1 can lead to chronic strongyloidiasis and a disseminated form of the disease, there is a high rate of response to the anthelmintic ivermectin.

Background: The prevalence of helminth infections exhibits an inverse association with the prevalence of Type 2 diabetes mellitus (T2DM), and helminths are postulated to mediate a protective effect against T2DM. However, the biological mechanism behind this effect is not known.

Aims/methods: We postulated that helminth infections act by modulating the pro-inflammatory cytokine and chemokine milieu that is characteristic of T2DM. Read More

Regulatory T cell expansion resolves after effective strongyloidiasis treatment in subjects with HTLV-1 co-infection.

Parasitol Int 2020 Jun 29;76:102092. Epub 2020 Feb 29.

Instituto de Medicina Tropical Alexander von Humboldt, Universidad Peruana Cayetano Heredia, Lima, Peru; Infectious Disease Division, Department of Internal Medicine, University of Texas Medical Branch, Galveston, TX 77555-0435, USA. Electronic address:

Background: Regulatory T-cells (Tregs) are increased in patients with HTLV-1/Strongyloides stercoralis co-infection, and they may modify otherwise protective antigen-specific cytokine production. We hypothesized that effective anti-helminthic treatment would decrease Tregs and restore antigen-specific cytokine responses.

Methods/results: We enrolled 19 patients with Strongyloides larvae in their stool by Baerman's test. Read More

Strongyloides Hyperinfection Presenting as a Gastric Outlet Obstruction.

Cureus 2020 Jan 8;12(1):e6603. Epub 2020 Jan 8.

Gastroenterology, Gastroenterology Associates of Brooklyn, Brooklyn, USA.

Strongyloides is a unique nematode in its ability to cause a secondary hyperinfection and disseminated disease several years following initial contact. The prevalence of Strongyloides infection has been rising; it is currently considered a global disease, which presents with a broad spectrum of clinical signs and symptoms among patients. This case report focuses on a 67-year-old Caribbean female presenting with severe weight loss, vomiting, early satiety, and mild anemia who was subsequently diagnosed with strongyloidiasis on the basis of a duodenal biopsy pathology report obtained via esophagogastroduodenoscopy (EGD).

Pathogens 2020 Feb 6;9(2). Epub 2020 Feb 6.

Hospital for Tropical Diseases, University College London Hospitals, London WC1E 6JB, UK.

Gastrointestinal (GI) symptoms are a frequent reason for primary care consultation, and common amongst patients with strongyloidiasis. We conducted a prospective cohort and nested case control study in East London to examine the predictive value of a raised eosinophil count or of GI symptoms, for infection in South Asian migrants. We included 503 patients in the final analyses and all underwent a standardised GI symptom questionnaire, eosinophil count and serology testing. Read More
