RESUMEN

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.

RESUMEN

The hydrographic basin of the Atoya river, located in the Department of Chinandega, one of the main cotton producing regions in Nicaragua, is intensively contaminated by pesticides. Samples of river waters and sediments, as well as strategically selected wells have been analyzed to study variations in the concentrations of organochlorine and organophosphorus pesticide residues between the dry season (November-April) and the rainy season (May-June). Generally, higher concentrations of pesticides have been detected in the river waters and sediments in the dry season. DDT, DDD, DDE compounds and toxaphene are the most frequent organochlorine residues found in the water and sediment samples, while endrin, aldrin, dieldrin and lindane are mainly found in the waters of rivers and wells. Organophosphorus compounds were rarely detected. However, residues of ethion, methyl-parathion and ethyl-parathion were found in high concentrations in some river and well water samples. Generally, organochlorine compounds tend to accumulate in the fine grain-size fractions, rich in organic matter, except DDE, which concentrates basically in the coarse grain-size fractions.
