An IgM monoclonal antibody (MAb) against a carbohydrate epitope present in Trypanosoma cruzi trypomastigote excretory-secretory antigens and expressed by different developmental stages of the parasite (epimastigote, trypomastigote and intracellular amastigote) was linked to a solid phase matrix and used as an antigen-capture antibody. Human serum complexes containing the epitope were then detected by using specific secondary antibodies against human immunoglobulin isotypes. Results of detection of IgM, IgG, and IgA serum complexes (SC) containing a T. cruzi polypeptide epitope showed that SC could be detected in 69% of the 13 Chagasic acute phase sera studied with IgG, in 84% with IgM, and in 75% with IgA. Only 16% (IgG-SC), 8% (IgM-SC), and 10% (IgA-SC) of chronic sera from 50 patients were positive. No patients with toxoplasmosis or rheumatoid factor were positive. Of the 11 leishmaniasis sera studied, four had IgG-SC, two had IgA-SC, and five had IgM-SC. Of the eight Yanomamo Indians infected by Onchocerca volvulus, three were found to have IgG-SC, two had IgM-SC, and two had IgA-SC. Thirteen sera from healthy individuals living in an endemic area were also studied. One subject had IgG IgM and IgA-SC. The results presented in this study show for the first time, the specific detection of IgM, IgG, and IgA immune complexes using a MAb against T. cruzi. The presence of the epitope in association with IgM antibodies in sera from patients with the acute phase of the disease suggests that this antigen(s) carrying the epitope that reacts with the MAb could be a marker(s) of active infection. In addition, the specificity of the serum complex capture assay allowed the detection of Chagas' disease in two different endemic areas (Argentina and Venezuela).

Levamisole is a drug of choice for treatment of ascariasis. With recommended dosages, it is virtually free of side effects. Single doses of 50 to 150mg will eliminate all parasites in 90 to 100% of ascariasis patients irrespective of worm burden. Activity against hookworms has been demonstrated for levamisole but the most effective treatment regimen has not been determined. Further drug trials are needed for better assessment of efficacy. Levamisole has little or no curative action on infections with whipworms and pinworms. It may have some activity against strongyloides but confirmatory studies are needed. It has been shown that levamisole has significant activity against microfilariae of Wuchereria bancrofti and Brugia malayi. It is not, however, as effective as diethylcarbamazine ('Hetrazan'), and side reactions are greater. In tolerated doses, levamisole does not have significant action on adult forms or microfilariae of Onchoceea volvulus. The drug applied topically, however, may find a place in treatment of ocular onchocerciasis. Limited trials with levamisole for toxoplasmosis and chronic cutaneous leishmaniasis have given promising results, and further studies are indicated.

Intestinal parasites are Giardia lamblia, Cryptosporidium parvum, Entamoeba histolytica, hookworms, ascaris, tape worms and others. As to organ parasites, their life-threatening courses are pointed out: amebiasis in the intestine, liver, lung and brain, toxoplasmosis in the brain, lung and heart muscle, including the danger for the child of a pregnant woman with an acute infection, West African sleeping sickness with encephalitis, the East African form with polyserositis, South American Chagas' disease with intestinal and myocardial involvement, visceral leishmaniasis Kala Azar, the filariasis Onchocerca volvulus with threatening blindness, the dog tapeworm with cysts and Echinococcus multilocularis with carcinoma-like infiltration of the liver and other organs, cysticercosis of the brain, eye and muscle tissue; partly generalizing parasitoses in immuno-suppressed including AIDS patients, finally skin parasites as causes of disease (e.g. scabies), and as potential carriers of pathogens.
