Strongyloides stercoralis is a soil-transmitted helminth (STH) widespread in various part of the world. A 78-yr-old peasant diabetic female from Mazandaran Province northern Iran, was admitted to Infection Department of the Razi Hospital in city of Qaemshahr, north of Iran complaining about abdominal skin rash, pruritus, itching, anorexia, nausea, vomiting, dysuria and cough. This patient had cutaneous migration effects of S. stercoralis larvae in her abdominal skin (larva currents and urticaria). Lung CT without contrast demonstrate s bilateral diffuse ground glass opacity draws attention...

Neglected tropical diseases (NTDs) are a diverse group of acute and chronic conditions with distinct characteristics that thrive mainly among the poorest populations, almost exclusively in tropical countries. To evaluate the relevance and impact of NTDs in a temperate area, the number and features of patients diagnosed with NTDs at the Infectious and Tropical Diseases Unit (ITDU), Azienda Ospedaliero-Universitaria Careggi, Florence, Italy between 2000 and 2015 were retrospectively reviewed. Overall 289 NTD cases were diagnosed in 283 subjects accounting for 2...

Strongyloides stercoralis is an intestinal nematode with a complicated lifecycle and auto-infection. In healthy individuals, this parasite usually does not cause any symptoms. But in immunocompromised patients, the symptoms vary from abdominal pain and discomfort to sepsis and death.Gastric infection and involvement by this nematode are rare and uncommon. Here we report 2 cases of Strongyloides stercoralis hyperinfection that were discovered in gastric biopsies in 2 immunocompromised patients. A gastric biopsy was taken for each patient and both showed cross sections of adult worms, eggs, and rhabditiform larvae of S...

Eosinophilia is a common laboratory finding in helminth infections but whether it is suggestive of neurocysticercosis (NCC) is controversial and inadequately studied. We determined the presence of eosinophilia (≥ 500 eosinophils/mm(3)) at clinical presentation in 72 patients with a proven or probable diagnosis of NCC and who had not received corticosteroids within 2 weeks of evaluation and complete blood count. Only two persons whose last possible endemic exposures to NCC were 7 and 6 years earlier had eosinophilia of 500 eosinophils/mm(3) and both had a positive antibody serology to strongyloidiasis...

Strongyloides venezuelensis is a parasitic nematode of rodents that is frequently used to obtain heterologous antigens for immunological diagnosis of human strongyloidiasis. The aim of this study was to identify antigens from filariform larvae of S. venezuelensis for immunodiagnosis of human strongyloidiasis. Soluble and membrane fractions from filariform larvae of S. venezuelensis were obtained in phosphate saline (SS and SM) and in Tris-HCl buffer (TS and TM), and were analysed by Western blotting. Different antigenic components were recognized by IgG antibodies from the sera of strongyloidiasis patients...

Radiologists seldom encounter parasitic diseases in their daily practice in most of Europe, although the incidence of these diseases is increasing due to migration and tourism from/to endemic areas. Moreover, some parasitic diseases are still endemic in certain European regions, and immunocompromised individuals also pose a higher risk of developing these conditions. This article reviews and summarises the imaging findings of some of the most important and frequent human parasitic diseases, including information about the parasite's life cycle, pathophysiology, clinical findings, diagnosis, and treatment...

The primary causative agent of eosinophilic meningoencephalitis (EoM) in endemic regions is the nematode Angiostrongylus cantonensis. The occurrence of EoM was previously restricted to countries in Southeast Asia and the Pacific Islands; however, more recently, it has been reported from other regions, including Brazil. The commonly used diagnosis is detection of specific antibody reactivity to the 31 kDa antigen, which is derived from female worm somatic extracts. Here we report the occurrence of cross-reactivity to this antigen in sera from other parasitic infections, especially those that may cause EoM, such as gnathostomiasis, toxocariasis, hydatidosis and strongyloidiasis...

Strongyloides stercoralis has the potential to cause accelerated autoinfection in immunocompromised hosts. Screening tests for strongyloidiasis may be falsely negative in the setting of immunosuppression. We report a case of Strongyloides hyperinfection syndrome in a patient with human T-lymphotropic virus type 1-associated T-cell leukemia early after hematopoietic stem cell transplant. The diagnosis was made by stool ova and parasite examination, despite a negative screening enzyme-linked immunosorbent assay...

Epidemiological study on strongyloidiasis in humans is currently lacking in Malaysia. Thus, a cross-sectional study was carried out to determine the prevalence of Strongyloides stercoralis infection among the inhabitants of longhouse indigenous communities in Sarawak. A single stool and blood sample were collected from each participant and subjected to microscopy, serological and molecular techniques. Five species of intestinal parasites were identified by stool microscopy. None of the stool samples were positive for S...

Pulmonary strongyloidiasis is an uncommon presentation of Strongyloides infection, usually seen in immunocompromised hosts. The manifestations are similar to that of acute exacerbation of chronic obstructive pulmonary disease (COPD). Therefore, the diagnosis of pulmonary strongyloidiasis could be challenging in a COPD patient, unless a high index of suspicion is maintained. Here, we present a case of Strongyloides hyperinfection in a COPD patient mimicking acute exacerbation, who was on chronic steroid therapy...

We review the most characteristic clinical and histopathologic findings of the cutaneous manifestations of the occlusive nonvasculitic vasculopathic disorders. Clinically, most of these conditions are characterized by retiform purpura. Histopathologic findings consist of occlusion of the vessel lumina with no vasculitis. Different disorders may produce nonvasculitic occlusive vasculopathy in cutaneous blood and lymphatic vessels, including embolization due to cholesterol and oxalate emboli, cutaneous intravascular metastasis from visceral malignancies, atrial myxomas, intravascular angiosarcoma, intralymphatic histiocytosis, intravascular lymphomas, endocarditis, crystal globulin vasculopathy, hypereosinophilic syndrome, and foreign material...

INTRODUCTION: Strongyloides stercoralis infection is more prevalent in tropical regions but autochthonous cases have been reported in Spain, mainly in La Safor (Valencia). The objective is to describe the strongyloidiasis cases registered in a regional hospital of Alicante province (Spain) and to determine if they were autochthonous cases. METHODS: Retrospective study of all diagnosed cases of strongyloidiasis in Vega Baja Hospital (Orihuela, Alicante) between January 1999 and March 2016...

BACKGROUND: Donor-derived Strongyloides stercoralis infection in solid organ transplant (SOT) recipients is uncommon. Immunosuppressed SOT recipients are at risk of developing severe forms of strongyloidiasis infection through transmission from an infected donor allograft. METHODS: PubMed was searched for English-written articles published up to April 2015. Articles that reported cases of donor-derived strongyloidiasis infection in SOT recipients were reviewed for a pooled analysis...

Helminthic infection and HIV have been reported to coexist, particularly in sub-Saharan African patients living with HIV. Strongyloidiasis is one of the most common helminths, usually leading to cutaneous and gastrointestinal (GI) symptoms. In the immunocompromised host, this infection can lead to strongyloidiasis hyperinfection syndrome (SHS), not common in HIV-infected patients. Immune reconstitution inflammatory syndrome (IRIS) can follow the initiation of antiretroviral therapy (ART), with a variety of presentations...
