Author reported a case of human infestation with Strongyloides stercoralis in a female patient, 65 years old, living in Hung Yen province, treated at Central Military Hospital 108 on August, 23rd, 2003. The clinical symptoms were prolonged diarrhea and anaemia. The examination of feces and duodenal juice finds out larvae of Strongyloides stercoralis. Sample blood presents an increase of eosinophilis. This patient was treated with thiabendazole (Mintezol) 25 mg/kg/day in 4 days and got good results. In a patient with prolonged unclear diarrhea, increased eosinophilis, living in epidemic area, it's considered infestation with Strongyloides stercoralis so that patient can be examined and tested appropriately. Early diagnosis will help patients receive specific treatment. Thiabendazol (Mitezol) and albendazol (Zentel) are effective drugs

A case of strongyloides stercoralis gastrointestinalis infection on a 88 years old of age women was admitted in Hospital No108 in the year 2003. The main symptoms were diarrhoea, anemia and abdominal pain. Fecal examination, gastroduodenal fluid and duodenal biopsy were performed. Strongyloides stercoralis and their larva were detected. Thiabendazole was defined was a treatment of choice

A case of Strongyloides stercoralis infection wss experienced in a 73-year old Korean female patient, was hospitalized with relapse of cholecystitis. The patient developed cough and dyspnea 17 days after the admission. On the 27th hospitalized day, diarrhoea, nausea, vomiting and abdominal pain started. A number of parasitic larvae were incubated at 25 C for 2 days. Typical fork tailed filariform larvae of S. stercoralis (Bavay, 1876) Stiles and Hassall, 1902, were identified after cultivation. There was no improvement of diarrhoea after the medication with mebendazole. After the administration of thiabendazole, however, diarrhoea was stopped. On the 6th day of medication, S. stercoralis larvae were no more detected, and thereafter no larva was observed by repeated stool examinations upto 2 months after chemotherapy. The patient had the history of administration of steroid for articular rheumatism. Therefore this case seems to be a hyperinfection of S. stercoralis due to an autoinfection and to be the first report on the hyperinfected strongyloidiasis in Korea. Related literature was briefly reviewed.

This survey examined the prevalence and intensity of Strongyloides fuelleborni kellyi and other intestinal helminths in children 5 years of age or under living near Kanabea, Papua New Guinea. Of 179 samples, 27% of the children tested positive for Strongyloides, with 81% of these children being a year or less in age. Overall, 68% of the children had one or more infections including Ascaris lumbricoides and hookworm (Necator americanus) as well as Strongyloides. Egg counts in the stools ranged from 100 to 98,300 eggs/ml for Strongyloides, 100 to 59,200 eggs/ml for Ascaris and 100 to 3400 eggs/ml for hookworm. There were significant associations between Strongyloides intensity and weight for age and weight for height such that children with higher intensities had, on average, lower z-scores. Relationships between the prevalence of helminth infections and socioeconomic factors were also observed. Logistic regression models showed that children living farther away from Kanabea (more than 2 hours' walking distance), in smaller households (5 or less people) and with uneducated mothers best predict children with Strongyloides. Two of these variables also predicted the presence of hookworm: maternal education and household size. However, in contrast to Strongyloides, a larger household size (6 or more people) was significantly associated with the presence of hookworm. House type was associated with the prevalence of Ascaris, with children living in houses with tin roofs being less likely to have Ascaris than those living in traditional houses. In addition, maternal education was associated with Ascaris intensity in those children with infection, such that the mean intensities were greater in children of uneducated mothers.

Strongyloides stercoralis is an intestinal nematode which infects a large portion of the world's population especially in tropical areas and other hot, humid regions. Because of an opportunistic nature of the parasite, the infection is confined to the intestinal tract in immunocompetent hosts. But, in individuals having immunocompromised state, the parasite is augmented by autoinfection, resulting in hyperinfection and/or systemic dissemination. In Korea, several cases of strongyloides hyperinfection were reported since 1959, especially who had corticosteroid therapy and other immunosuppressive medications. We experienced a case of strongyloides hyperinfection, accompanied with terminal stage of stomach cancer. The patient responded to treatment with albendazole. After one month later, repeated follow-up stool exam revealed clearance of the larvae from the patient' feces. So, we report this case with the literature.

Strongyloides stercoralis hyperinfection syndrome is a rare complication of strongyloidiasis that frequently occurs in immunosuppressed patients. The parasite ordinarily localizes in the small intestines, especially in the duodenal and jejunal part. Reports of gastric involvement are rare. We report a case of an immunosuppressed patient who had severe S. stercoralis infection of the stomach in association with purulent meningitis.

A 73-year-old Korean male was admitted to Jeil hospital with clinical complaints of backache, cough, sputum, vomiting and diarrhea. He had a history of long term administration of prednisolone. At admission he was comatose and showed generalized pitting edema and anasarca. Laboratory data revealed leukocytosis, hyperproteinemia with hypoalbuminemia, sepsis, anemia and brown-colored urine. Stool examination revealed rhabditiform nematode larvae. By fecal cultivation, filariform larvae of Strogyloides were obtained and the patient was diagnosed as hyperinfection syndrome due to S. stercoralis infection. On the 3rd day of hospitalization, albendazole treatment was started and continued for 4 days. On the 7th dsy of hospitalization, sputum revealed filariform larvae. Total 619 parasitic adult females, expelled by chemotherapy, were collected from the diarrheal stool. However, the patient was discharged hopelessly and died at home.

Strongyloides stercoralis is an intestinal nematode with a complex life cycle, including a free living cycle, a parasitic cycle, and an auto-infection cycle. S. stercolaris infection may occur in both immunocompetent and immunocompromised individuals. It is usually asymptomatic and undetectable for decades in a healthy host. In immunocompromised patient, however, it may cause life threatening hyperinfection involving multiple organs. In Korea, several cases of Strongyloides hyperinfection have been reported since 1959. However, reports with gastric involvement and peritoneal invasion are rare. This is a report of gastric strongyloidiasis hyperinfection identified at ascites in an elderly patient who had subtotal gastrectomy due to stomach cancer.

Strongyloides stercoralis is a nematode that may involve any segment of the Gl tract or virtually every human organ because of its autoinfection cycle and hyperinfection. It may occur in either immunocompetent or immunocompromised individuals. A 72-year-old woman who had no notable medical history presented with chronic diarrhea and generalized edema and she revealed protein losing eneteropathy. She was diagnosed with Strongyloidiasis infection through EGD and a colonoscopic biopsy specimen at a time when there were rhabditiform larvae present. The patient was treated with albendazole 400 mg/day for three days. At the follow-up three months later, the endoscopic biopsy specimens revealed no evidence of Strongyloidiasis infection and her clinical symptoms had progressively improved. The present case represents a rare report of Strongyloidiasis in a immunocompetent patient diagnosed through EGD and the colonoscopic biopsy specimen concurrently. So, we report on this case along with a review of the relevant literature.
