INTRODUCTION: The manifestations of anisakiasis are essentially digestive pain, nausea or transit disorders. When it is initially asymptomatic, it is later revealed by a major complication, which is occlusion on an eosinophilic granuloma of the ileum. Over the past 5 years, the international literature has reported allergic manifestations related to this helminthozoonose, such as urticaria, angioedema, bronchospasm and occasionally anaphylactic shock. OBSERVATION: A 60 year-old man presented with an anaphylactic shock and diarrhea. One month later, he exhibited persisting asthenia, cough and intermittant pruriginous rashes. Blood hypereosinophilia was borderline and total IgE was clearly increased. The initial event was retrospectively labeled "histaminic shock following ingestion of tuna fish". The discovery of highly positive anisakiasis serology, conducted simultaneously in 2 different laboratories, corrected the diagnosis. The patient was treated with albendazole (10 mg/kg/day for 7 days) with excellent results on the clinical and biological symptomatology. CONCLUSION: With the occurrence of an allergic reaction, whether major or minor, a notion of ingestion of fresh fish must be searched for and, if positive, an immunodiagnosis of anisakiasis must be requested. Any seriological positivity should be controled by gastro-duodenal endoscopy. If the search for larvae is negative, we recommend anthelminthic treatment as a precaution.
Cysticercosis is a zoonotic disease of humans produced by the larval stage of swine parasite, Taenia solium. Chemotherapy of infected pigs is a possible strategy for avoiding disease transmission and improving health programs in endemic areas of cysticercosis. In this preliminary study, seven naturally infected pigs from 6 to 12 months of age were allotted to treated (n = 4) and control groups (n = 3). The treated animals received a subcutaneous injection in their forelegs and thighs of 15 mg/kg per body weight of albendazole sulphoxide (ABZSO; Pisa, Mexico) once per day for 8 days. At the same time, the control group received a subcutaneous injection of saline solution (9% NaCl). After 12 weeks, all the animals were slaughtered and at least 200 metacestodes were isolated from the muscles and brain of each animal. Using histology and the metacestode viability criteria described in this study, treated animals had no viable cysts in their muscle (0/200), while 7 of 17 (41.1%) viable cysts were observed in those isolated from their brains. In the control group, 183/200 (91.5%) muscle metacestodes were viable and from brain, 22/29 (75.8%) metacestodes were viable. The 15 mg/kg per body weight dosage of ABZSO was 100% effective against muscular cysticercosis as shown by the lack of viable cysts and the micro-calcifications in meat from the treated pigs.
Compounds 1-18 have been synthesized and tested in vitro against the protozoa Giardia lamblia, Entamoeba histolytica and the helminth Trichinella spiralis. Inhibition of rat brain tubulin polymerization was also measured and compared for each compound. Results indicate that most of the compounds tested were more active as antiprotozoal agents than Metronidazole and Albendazole. None of the compounds was as active as Albendazole against T. spiralis. Although only compounds 3, 9 and 15 (2-methoxycarbonylamino derivatives) inhibited tubulin polymerization, these were not the most potent antiparasitic compounds.
