University of the Ryukyus, Nishihara, Japan.

A 74-year-old woman carrying the human T-lymphotropic virus type-1 (HTLV-1) presented with abdominal pain and vomiting. Computed tomography and microscopic analysis of the gastroduodenal drainage fluid made a diagnosis of paralytic ileus due to hyperinfection with underlying HTLV-1 infection. Strongyloidiasis should be included in the differential diagnosis for paralytic ileus in patients who have lived in or migrated from the endemic regions. Read More

Department of Clinical Sciences, Faculty of Veterinary Medicine, Utrecht University, Yalelaan 108, 3584 CM, Utrecht, The Netherlands.

Background: The adult worms of Angiostrongylus vasorum reside in the pulmonary artery of dogs and can lead to cardiac, respiratory, and central neurologic signs. Due to luminal obstruction and perivascular inflammation of the pulmonary artery branches, pulmonary hypertension can arise. Pulmonary hypertension, in turn, can lead to severe damage of the right-sided cardiac structures, leading to right ventricular remodeling and tricuspid valve regurgitation. Read More

Fatal outcome in a patient under immunosuppressant therapy infected with human T-lymphotropic virus type 1 (HTLV-1), cytomegalovirus (CMV) and Strongyloides stercoralis: a case report.

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.

Pulmonary angiitis is a small vessel vasculitis commonly reported in granulomatosis with polyangiitis (GPA) but is rarely attributed to angiostrongyliasis. We report a case of a patient with well-controlled rheumatoid arthritis, who was treated for GPA based on lung biopsy results with glucocorticoids (GC). Upon re-review of the initial pathology, along with peripheral eosinophilia and history of recent travel, the patient was eventually diagnosed with angiostrongylus-like nematode infection. Read More
