“…Most studies conducted to date are heterogeneous, incomplete, and of a retrospective nature, reporting wideranging prevalences from 0.6% to 40%, with the disease being regarded as endemic in all of them. [12][13][14][15][16][17][18][19] In 1992, the first study of the prevalence of intestinal parasites based on a representative sample of immigrant migrant workers on farms in North Carolina was published. Larvae of S. stercoralis were detected in 4% based on the microscopic examination of stools.…”

Abstract. Strongyloidiasis is a parasitosis characterized by persistent infection before dissemination and the development of potentially fatal disease. Since diagnosis is difficult, knowledge of the prevalence and geographic distribution of the disease is of practical importance. A study was made of Strongyloides stercoralis infection in a random and representative sample of farm workers in a tourist region in Spain based on the detection of larvae of triple stool samples. The prevalence of infection was 12.4% (95% confidence interval [CI] ‫ס‬ 8.4−16.4). None of the 26 clinical or epidemiologic variables analyzed were found to be predictive of infection. Only eosinophilia (> 400 eosinophils/mm 3 ) was significantly greater among the infected individuals (odds ratio ‫ס‬ 73.4, 95% CI ‫ס‬ 16.3−327.0), with a sensitivity of 93.5% and a specificity of 93.1%. A screening program is proposed to detect eosinophilia, to provide treatment without stool examinations, and thus afford a cost-effective policy for preventing the development of severe forms of the disease among specific risk groups where the prevalence of other parasitoses is low.

Diagnosis and treatment of Strongyloides stercoralis infection can be difficult, and a high degree of clinical suspicion in patients who have visited an endemic area is required. We describe the epidemiology and clinical features of 152 prospectively identified cases of strongyloidiasis in an European region, and identify risk factors for the development of severe forms of the disease. This was a prospective study of all patients admitted to a single institution over an 8-year period. Patients (n=152) were mainly elderly male farmers (79%) who had acquired the disease by working barefoot in contact with soil and ingesting non-drinking water. Eosinophilia was a sensitive marker for the infection (82%). Twenty patients (13%) developed severe forms of the illness and six patients (4%) died. A significant association was found between severe forms of strongyloidiasis and steroid usage (OR 9.0, 95%CI 2.1-37.6), immunodebilitating illness (OR 10.1, 95%CI 3.2-32.3) and other immunosuppressive therapy (OR 13.7, 95%CI 2.9-58.7), but by logistic regression analysis, only immunodebilitating disease was as a risk factor (OR 2.1, 95%CI 1.78-2.43). S. stercolaris infection is endemic in the Spanish Mediterranean coast. The frequent development of severe forms of the disease, with a high mortality, makes early recognition and treatment essential.
