The strongyloidiasis is a parasitic disease that poses as a serious public health problem, mainly in tropical and subtropical countries. Over the years, some conditions, such as advances in corticosteroid treatment and immunosuppressive diseases, have improved not only the increase in cases of strongyloidiasis, but also the emergence of severe forms of the disease and / or deaths. For these reasons, the objective of this study is to make a critical analysis of the occurrence of strongyloidiasis in patients with comorbidities, describing clinical and epidemiological characteristics associated with these diseases that can highlight the importance of monitoring this parasitosis in most susceptible groups...

Strongyloidiasis is a parasitic neglected disease caused by the nematode Strongyloides stercoralis affecting 30 to 100 million people worldwide. Complications, strongly associated with alcoholism, organ transplants, and HTLV-1 virus, often arise due to late diagnosis, frequently leading to patient death. Lack of preemptive diagnosis is not the only difficulty when dealing with this parasite, since there are no gold standard diagnostic techniques, and the ones used have problems associated with sensitivity, resulting in false negatives...

BACKGROUND: Chronic parasitic infections are associated with active immunomodulation which may include by-stander effects on unrelated antigens. It has been suggested that pre-natal exposure to parasitic infections in the mother impacts immunological development in the fetus and hence the offspring's response to vaccines, and that control of parasitic infection among pregnant women will therefore be beneficial. METHODOLOGY/PRINCIPAL FINDINGS: We used new data from the Entebbe Mother and Baby Study, a trial of anthelminthic treatment during pregnancy conducted in Uganda, to further investigate this hypothesis...

Strongyloidiasis is one of the neglected tropical diseases caused by infection with the nematode Strongyloides genus and distributed worldwide. Strongyloidiasis can be fatal in immunosuppressed patients induced hyperinfection or disseminated strongyloidiasis. Unfortunately, until now, due to the unspecific clinical symptom in infected individuals and the low sensitivity diagnosis of strongyloidiasis, many patients were misdiagnosed every year. Furthermore, the larvae of the Strongyloides stercoralis (S. stercoralis) is similar to other nematodes such as hookworm, Trichostrongylus increased the difficulty of diagnosis...

Intestinal parasites are a common pathology in the pediatric practice, constituting a major public health problem. Currently their epidemiology, especially in countries like Ecuador where there are populations and communities where health services are scarce or difficult to access. We report the case of a child with chronic grade 3 malnutrition, from Sarayacu province of Pastaza, Ecuador an endemic area in several parasitosis. The clinical features were lower gastrointestinal bleeding added to chronic anemia and eosinophilia...

Strongyloidiasis is an infection caused by the parasite Strongyloides stercoralis, which can be asymptomatic and means a high morbidity and mortality in immunocompromised hosts, severe malnutrition and coinfection with HTLV-1 virus. The parasite has the potential to produce and multiply internal autoinfection in humans, thus an hyperinfection can be developed. A case of pulmonary infection by this parasite is presented in this study, infection which advanced into a respiratory failure and required mechanical ventilation and hemodynamic support in an intensive care unit...

Strongyloidiasis is usually an asymptomatic disease in immunocompetent patients, caused by Strongyloides stercoralis. However, in immunocompromised patients it can produce a severe clinical profile. Therefore, a correct diagnosis is necessary in these cases and in those chronic asymptomatic patients. The low sensitivity of classical parasitological techniques requires the analysis of multiple serial stool samples. Molecular diagnostic techniques represent an improvement in the detection of the parasite. The objective of this study was to evaluate the minimum number of samples necessary to achieve maximum sensitivity by real-time polymerase chain reaction (PCR)...

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...
