title: [Trichinosis: new epidemic outbreak caused by the ingestion of wild-boar sausage].
abstract: After the evaluation of 129 serum samples of persons who had ingested boar sausage infested by Trichinella spiralis, 48 individuals (40 adults and 8 children) with a mean age of 38.8 years were diagnosed of trichinosis. The incubation time was 17 days (range 2 to 44 days). The following clinical features were outstanding: facial and eyelid edema (50%), diffuse limb myalgia (43%), fever (37%), conjunctivitis (25%), headache (16%), and abdominal pain (16%). Remarkably, 33% of the diagnosed patients were asymptomatic. The diagnosis was made by an indirect immunofluorescence technique (IIF), which was considered as positive when the titer was higher than 1/20 after considering seroconversion at the beginning of the disease and after 4-6 weeks. Among laboratory abnormalities there was leukocytosis in 15 patients and eosinophilia in 37. The GOT, GPT and CPK enzymes were only slightly increased in a small proportion of patients (8, 10, and 31%, respectively). Forty patients were treated with thiabendazole, associated or not to corticosteroids, which was well tolerated. Eight patients were not treated. One year after the diagnosis a new laboratory control was undertaken in 43 patients (all asymptomatic). Eosinophilia was still present in 12, and the titers against Trichinella were high in all. However, the percentage of the titer was smaller than at the beginning of the outbreak.
