Fifty-two of 142 (37%) American ex-prisoners of war that worked on the Burma-Thailand Railroad during World War II were found to have previously unrecognized symptomatic Strongyloides stercoralis infections. A characteristic urticarial creeping skin eruption on the abdomen, buttocks and thighs occurred in 92%. Infection was also associated with pruritus ani, abdominal pain, indigestion, heartburn, and diarrhea. Demonstration of larvae in ether-formalin stool concentrates in these chronic low density infections required 5 hours of microscopy per case to detect 90% of positive cases. Therapy with thiabendazole resulted in a clinical cure in 93% and a microscopic cure in 100%; but was associated with frequent side effects. Chronic strongyloidiasis should be considered in veterans of Far East conflicts and in others with intimate soil contact in rural Strongyloides stercoralis-endemic areas who present with recurrent creeping skin eruption, abdominal pain, and eosinophilia.

One hundred and sixty ex-servicemen who had been prisoners of war in south-east Asia during 1942-5 were investigated for infection with Strongyloides stercoralis. Larvae were found in 44 (27.5%) of the men, who had therefore been infected for 34-37 years. Direct microscopy of the faeces was the most successful diagnostic method, giving a positive result in 37 cases (84%); multiple examinations were often necessary. Faecal culture was positive in 30 cases (68%), but examination of duodenal fluid obtained with the string test gave a positive result in only 17 (39%). The mean blood eosinophil count and mean serum IgE concentration were higher in the infected men, though normal values were often found in individual cases. Clinical manifestations of isolated strongyloides infection were analysed by comparing the infected men with control groups of ex-prisoners in south-east Asia without proved strongyloidiasis and ex-prisoners in Europe. Twenty-nine infected men (66%) complained of non-specific urticaria, and 13 (30%) had pathognomonic larva currens. Gastrointestinal symptoms significantly more common in the infected group were diarrhoea, indigestion, lower abdominal pain, pruritus ani, and weight loss (p <0.05-p <0.0005).The study group was thought to be reasonably representative of Allied ex-servicemen imprisoned in south-east Asia during the second world war. Probably there are many thousands of infected persons in several countries. The worm has an unusual ability to multiply, and larvae may spread throughout the body in immunosuppressed subjects.

Treatment of strongyloidiasis has been traditionally based on thiabendazole, despite its frequent gastrointestinal side effects and failure to achieve eradication of the parasite from faeces in approximately 30% of cases. Ivermectin has been shown to be more effective for treating chronic uncomplicated strongyloidiasis. The efficacy and tolerability of these drugs in a series of patients treated from 1999 to 2002 at the Oliva Health Centre, Valencia, Spain, are reported. A total of 88 patients diagnosed of strongyloidiasis were treated using the following regimens: thiabendazole 25 mg/kg/12 h for 3 consecutive days in 31 patients; ivermectin 200 mug/kg as a single dose in 22 patients; and ivermectin 200 mug/kg for 2 consecutive days in 35 patients. The efficacy and side effects were recorded. A total of 65 patients were male, and 23 female. The mean age was 64 +/- 12 years. Of the patients, 44 had worked barefoot in rice fields. Among the 31 patients treated with thiabendazole, 25 (78%) met the criteria for cure (the absence of parasite in faeces after examination of three samples collected on alternate days), and 5 (16%) experienced side effects (asthenia, epigastralgia and disorientation). Of the 22 patients treated with ivermectin on a single day, 17 (77%) met the criteria for cure, and 2 (9%) reported side effects (dizziness, dyspepsia). Among the 35 patients treated with ivermectin on 2 consecutive days, 100% met the criteria for cure, and 0% experienced side effects. In chronic uncomplicated strongyloidiasis, a treatment regimen consisting of ivermectin 200 mug/kg for 2 consecutive days provided the best results with regard to efficacy and tolerability. When the eosinophilia continued after treatment, we observed a high percentage of not-cure rate (7 of 9 patients, 77%).

Strongyloides stercoralis affects 30 to 100 million people worldwide and is a common cause of abdominal pain and diarrhea. Strongyloidiasis is a chronic and limited disease; however, in immunocompromised patients, hyperinfection syndrome can occur. Diagnosing strongyloidiasis early is important, as almost all deaths due to helminths in the United States are due to S stercoralis hyperinfection. Patients infected with human immunodeficiency virus (HIV) do not appear to be at an increased risk for S stercoralis hyperinfection. We report a case of an HIV-infected Hispanic woman presenting with dyspepsia, emesis, abdominal pain, and diarrhea diagnosed with S stercoralis on an esophagogastroduodenoscopy biopsy of the duodenum. The diagnostic workup had been inconclusive and deciding to biopsy the small bowel based on the nonerythematous boggy appearance of the duodenal folds was the key step in making the correct diagnosis. Early diagnosis and treatment thwarted the developing hyperinfection syndrome and likely prevented further morbidity and probably saved her life.

We report a case of strongyloidiasis in a patient born in Hong Kong and was possibly infected via her prior occupation in conservancy services. She presented with chronic diarrhoea, anorexia, and extensive scratch marks over the lower extremities. Further assessment yielded eosinophilia, intermittent dyspepsia, and an episode of unexplained Clostridium perfringens bacteraemia. She was treated with a course of albendazole. Subsequently, the eosinophilia and diarrhoea subsided.

Here, we report the case of a 57-year-old Peruvian man on long-term corticosteroid therapy for a drug allergy and proton pump inhibitors for chronic dyspepsia symptoms. Upper gastrointestinal endoscopy showed multiple white granular lesions and widespread erosions in the stomach. Our findings indicate that gastric strongyloidiasis should be carefully considered in high-risk patients even if endoscopic findings are nonspecific.
