We retrospectively studied 343 consecutive patients treated between 1979 and 1992. Ninety patients whose stool was not examined were excluded. Fifty-three patients with strongyloidiasis were compared with 200 controls with regard to outcomes and the following characteristics: age, sex, underlying disease, use of corticosteroids, abdominal pain, diarrhea, fever, pulmonary symptoms, and eosinophilia. Patients with strongyloidiasis more commonly had eosinophilia (P = .01) and fever (P = .03). There was a single but fatal case of the disseminated disease syndrome (1.9% of patients with strongyloidiasis). In multiple logistic regression analysis, the factors predictive for strongyloidiasis were schistosomiasis (odds ratio [OR], 6.58), ascariasis (OR, 2.78), and the use of steroids (OR, 2.29). Strongyloidiasis was highly prevalent among patients with hematologic malignancies in Brazil. Occurrence of the disseminated disease syndrome seems to be unusual.

Human strongyloidiasis is an important health problem in the southeast region of Peruvian Amazon, due to its prevalence and long term morbidity. An epidemiological study was conducted in the Peruvian Amazon area of Puerto Maldonado to determine the prevalence of strongyloidiasis in the population. Stool samples were collected from 1,133 patients at the outpatient department of our clinic. Strongyloidiasis affected 221 examined patients (20%). Prevalence was highest in males, mostly in children and elderly men. People living in urban and marginal urban areas, those coming from outside the region, and Andean people, showed the highest prevalences. Pre-school children were more likely to be parasitized than older children. The most common symptoms were diarrhea (55%), abdominal pain (32%) and cough (53%). One in 7 (13%) affected patients presented with moderate or severe symptoms, including life-threatening complications. Other intestinal parasites were found frequently in patients diagnosed with strongyloidiasis. Improved human waste disposal services are considered to be the main requirement to reduce the high prevalence of this disease.

The diagnosis and management of strongyloidiasis present a continuous challenge in developing countries including Taiwan. In this study, the clinical characteristics and microbiological findings of 27 patients with Strongyloides stercoralis infection were retrospectively analyzed. Intestinal infection was identified in 17 patients and hyperinfection syndrome or disseminated disease in 10 (including 2 autopsy cases). The most frequent clinical findings were diarrhea (74%), fever (70%), abdominal pain (59%), cough (37%), dyspnea (33%), and constipation (26%). The common initial laboratory abnormalities were leukocytosis (81%), anemia (67%), liver function impairment (52%), and eosinophilia (44%). Most of the 27 patients had comorbid conditions, including malnutrition in 20 (74%), corticosteroid dependence in 15 (55%), chronic obstructive pulmonary disease in 9 (33%), chronic liver disease or cirrhosis in 8 (30%), and peptic ulcer disease in 7 (26%). There was no difference in the time interval from symptom onset to diagnosis between the intestinal infection group and the hyperinfection/disseminated group (22 +/- 15 vs 17 +/- 9 days). Larvae of S. stercoralis were identified in the stool of 24 patients, in the sputum smear of 5, in the gastric biopsy of one, and on histology of autopsy specimens in 2. Twenty-six patients received antiparasitic drug therapy of variable duration (mebendazole in 24, albendazole in 2, combined therapy in one). The overall cure rate was 52% (14/27). Relapse occurred in 4 patients. The overall mortality was 26% (7/27). There was a high mortality (up to 50%) in the hyperinfection/disseminated disease group. In conclusion, diagnosis of strongyloidiasis is often delayed and overlooked because of nonspecific symptoms. Physicians in endemic regions should include strongyloidiasis in the differential diagnosis when patients present with gastrointestinal and/or pulmonary symptoms with peripheral eosinophilia.

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 degrees 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.

Strongyloides stercoralis is the only parasite which can produce a chronic illness in humans, being through autoinfection. This nematode can also provoke death when patient's immunologic state deteriorates producing a massive hyper infection. The first patient with strongyloidiasis who has always lived in the Galician South area is described. The clinical picture consisted of unspecific cutaneous lesions and abdominal pain with severe peripheral eosinophilia (> 20,000/ml. The diagnosis was carried out observing the larvae in the fecal examination and was confirmed with a culture. Treatment with albendazole failed and the healing was reached with ivermectin. We must consider the possibility of strongyloidiasis because misdiagnosing these patients as eosinophilic gastroenteritis there would be a higher risk of hyperinfection if they are treated with corticosteroids.

A retrospective study was carried out to evaluate the clinical course and outcome of disseminated strongyloidiasis treated in a regional hospital in Hong Kong over a 10-year period. Seven cases were identified, and the case history of each patient was analysed. The most common presenting symptom was fever (100%). Five (71%) patients had gastrointestinal symptoms, the most common being abdominal pain and diarrhoea. Three (42%) patients had a significant drop in haemoglobin. Six (85%) patients had bronchoalveolar infiltrates on chest radiographs. Most patients were immunosuppressed by means of steroid treatment for their underlying primary disease. One patient was diabetic, and another had lymphoma and was receiving chemotherapy. Strongyloides larvae were identified in stool specimens in two patients, in sputum smears in two patients, and in gastric biopsies in three patients. Five (71%) of the patients with lung involvement progressed to respiratory failure and died. Two (29%) cases were complicated by gram-negative bacterial infection. No patient had eosinophilia on presentation. All patients received antihelminthic treatment of variable duration. The case fatality rate in the cohort was 71% despite aggressive supportive therapy. Pulmonary and bowel symptoms were prominent in our series. In conclusion, the diagnosis of disseminated strongyloidiasis is often delayed because of nonspecific presenting symptoms. Early diagnosis relies on a high index of clinical suspicion, especially in immunocompromised hosts. Screening for Strongyloides infection before the initiation of immunosuppressive therapy should be considered, especially in endemic areas.

We report an immunodeficient patient with a rare gastrointestinal manifestation. A 26-year-old male with common variable immunodeficiency (CVID) and bronchiolitis obliterans, who was on intravenous gamma-globulin and prednisone, presented diffuse abdominal pain, nausea, vomiting and constipation of 3 days' duration. He reported 5 years of recurrent respiratory infections and diarrhea with negative stool tests, including tests for Strongyloides stercoralis. A physical exam revealed a poor general condition, anemia, dehydration and a distended painful abdomen with guarding, without abdominal sounds. The radiological study showed marked dilation of the small bowel that was edematous. Resection of the affected loop was performed and the histopathologic study showed transmural infection with S. stercoralis and hemorrhagic necrosis of the muscular layer, without mucosal destruction. The patient developed malabsorption syndrome and septic shock; he was treated with antibiotics and thiabendazole and was finally discharged in a good general condition. CVID is a rare disease and its association with systemic strongyloidiasis is very uncommon, but it has been reported in patients on corticosteroids. Hemorrhagic necrosis of the muscular layer without mucosal destruction was not found in the literature studied.

Mesenteric lymph node involvement in Strongyloides stercoralis hyperinfective states, described as an autopsy finding, remains a relatively poorly recognized and possibly underreported, antemortem phenomenon. Furthermore, the occurrence of S stercoralis mesenteric lymphadenopathy as a tocsin of bowel strongyloidiasis and the clue to the cause of intestinal pseudo-obstruction are undescribed. We report S stercoralis mesenteric lymphadenopathy and intestinal pseudo-obstruction in 5 HIV seropositive male patients, 21 to 42 years, who presented with abdominal pain and variable vomiting, diarrhea, and constipation. All were pale, pyrexial, and emaciated with abdominal distension. The preoperative diagnosis was intestinal obstruction. Poor clinical response on conservative therapy necessitated laparotomy. Dilated small bowel loops, ascites, and mesenteric lymphadenopathy were consistently noted; a diagnosis of pseudo-obstruction due to underlying tuberculosis or lymphoma was made. The mesenteric lymph nodes were biopsied. The pertinent nodal features were a dense infiltrate of eosinophils, eosinophil microabscesses and degranulation, a focal Splendore-Hoeppli phenomenon, and randomly disposed, but elusive, S stercoralis filariform larvae. Clinical deterioration confirmed intestinal complications at repeat laparotomy. Intestinal resections were performed in 4 patients; histopathologic appraisal confirmed intestinal strongyloidiasis. All patients died within 3 to 7 days after surgery. Heightened awareness of S stercoralis mesenteric lymphadenopathy as a sentinel of intestinal strongyloidiasis and etiopathogenetic clue of intestinal pseudo-obstruction may allow timely diagnosis and medical treatment and avoidance of further surgery, potentially reducing the long-term morbidity associated with S stercoralis hyperinfection.

Strongyloidiasis, caused by Strongyloides stercoralis, is diagnosis considered as a challenge to clinician and laboratory technician. Because the auto-infective larvae are difficult to eradicate, one regimen dose may be in-sufficient and re-treatment of patients on two occasions, at 1 and 2 months after the initial treatment dose was recommended. This re-treatment regimen has yet to be proven in clinical trials. This study was performed on 24 patients who completed the study and having Strongyloides larvae in their stool obtained from Mansoura University Hospitals. Each stool sample was examined by direct saline smear, the formalin-ether sedimentation technique and agar plate culture. Patients were treated with Mirazid double course for a month to be followed up by stool examination by traditional method and agar plate culture for three consecutive months. In this study five cases out of 24 were asymptomatic (20.8%). Symptoms include abdominal manifestations as nausea and vomiting (16.7%), epi-gastric pain and nausea (12.5%), generalized abdominal pain (12.5%), chronic diarrhea (16.7%), irregular bowel habit (8.3%), and urticaria with abdominal pain (4.2%). Agar plate culture gave 100% positivity, even in cases were negative by coprological methods either direct smear and/or sedimenttation technique. All cases were cured by Mirazid given for one month except three resistant cases. Only one case responded to repeated course of Mirazid, while the other two cases still had larvae in their stool by agar culture plate. On combined therapy of both Mirazid and Mebendazole, larvae could be eliminated from their stool as approved by agar plate culture.
