“…6,7 Since the Hospital of Gandia (in Valencia on the Mediterranean coast of Spain) opened in 1984, relatively frequent cases of strongyloidiasis have been documented among patients hospitalized for other reasons. 8,9 A prospective clinical study was made over an eight-year period involved 152 infected patients (almost all farm workers). In this study, 13% presented with severe forms of the disease, and the mortality rate was 30%.…”

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.

Effect of parasitosis on allergic sensitization in rats sensitized with ovalbumin: Interaction between parasitosis and allergic sensitization

et al. 2007

Some helminthic infections, especially nematode infections, may behave as allergens and induce allergic sensitization. In this study, the investigators explored whether infections with Syphacia muris and Aspiculuris tetraptera have any effect on the development of allergen-induced cytokine responses and serum total immunoglobulin E (IgE) levels in ovalbumin (OVA)-sensitized rats. Four groups of male Wistar rats were studied. OVA sensitization was generated in 2 groups of rats; the rats in 1 group were infected and those in the other group were not. On day 21 after sensitization, tumor necrosis factor-alpha, interleukin-10, and total IgE levels in serum samples of rats were measured by enzyme-linked immunosorbent assay. The results showed that average concentrations of tumor necrosis factor-a and interleukin-10 were significantly greater in the group of rats infected with parasites and sensitized to OVA compared with the group uninfected with parasites and sensitized to OVA (P=.043 and P=.046, respectively). Upon comparison of total IgE concentrations, the group of rats infected with parasites and given saline solution showed higher levels compared with the group uninfected with parasites and given saline (P=.004). In conclusion, the investigators were unable to show a protective effect of an existing parasitic infection against the development of allergic sensitization upon exposure to OVA.
