[Comparative evaluation of a latex agglutination test, two Elisa tests and a Western blot test for the serodiagnosis of human trichinellosis].

Serology is a helpful test for the diagnosis of human trichinellosis because clinical signs of this disease (fever and myalgias) are non specific. A lot of techniques have been studied but very few are commercialized and have been comparatively evaluated. We report here the performances of 4 commercially available kits: two Elisa tests, one western blot test & one latex agglutination test. The specificity and sensitivity of the different tests were assayed on 60 sera from patients with a proven trichinellosis and on 70 controls. The four tests had a 100% sensitivity. The specificity was of 98.6% for the western blot, of 93% for the latex agglutination test and of 87 & 77% for the two Elisa tests. Cross reactions are mainly observed in patients with other helminthic infections.

[Schistosoma mansoni and haematobium antisera tested by homologous and heterologous antigens. Comparison of the results obtained by indirect immunofluorescence technic].

The study of anti Schistosoma mansoni and anti Schistosoma haematobium sera by homologous and heterologous antigen shows that Schistosoma haematobium has an immunogenic strength as good as that of Schistosoma mansoni. The joint use of the two antigens can be useful in epidemiologic investigations in Africa so as to track down seats of Schistosoma mansoni and Schistosoma haematobium and the prevalence of the infection.

[Comparative study of the value of Schistosoma mansoni and Schistosoma haematobium antigens in the indirect immunofluorescent reaction applied to the diagnosis of rectal S. intercalatum bilharziasis].

A comparative study of the value of antigenic sections of S. mansoni and S. haematobium in indirect immunofluorescence applied to the diagnosis of S. intercalatum rectal bilharziosis (in 66 cases) shows that far better results are obtained with S. haematobium antigen (83,3 0/0 positive reactions with higher titers dilution) than with S. mansoni (33,3 0/0 positive reactions).

[Wuchereria bancrofti and asthmatic pulmonary signs in Upper Egypt].

A biological and clinical survey was conducted in 25 patients with bancroftian filariasis, consulting the El Nikhela Health Centre, Assiout Governorate, Upper Egypt. Eleven patients showed asthmatic bronchitis. According to parasitological and serological data (specific antibodies level, total IgE), those clinical manifestations cannot be considered as a part of the "eosinophilic lung" syndrome. In this area, where Wuchereria bancrofti has been recently introduced and where there is an increasing degree of infection, bancroftian filariasis seems to predispose to allergic manifestations.

[Drug resistance of Plasmodium falciparum and Plasmodium vivax strains in Cambodia (Cardamone Massif). Morphological characteristics of Plasmodium vivax].

The authors report some failures of chemoprophylaxis and curative treatment of Plasmodium falciparum and Plasmodium vivax malaria. These infections were contracted in the area of the cambodian-thaï border by 8 Europeans treated by various regimens and 34 Cambodians treated by quinine. In the latter group, the quinine failure rate in Plasmodium falciparum infections was about 47% (RII or RIII?) and 17,5% in Plasmodium vivax. Total cure of vivax malaria with usual doses of Primaquine among the Europeans, failed in 3 out of the 6 treated patients. Morphological particularities (abnormal pigment, lack of Schüffner dots) were noticed in these Primaquine resistant vivax strains. A possible relation is considered between Primaquine resistance and these morphological particularities.

[Epidemiologic study of 2 foci of Schistosoma mansoni bilharziasis in Togo (Lama Kara and Kpalimé). Comparative efficacy of oltipraz (RP 35972)].

The authors note a very high prevalence of schistosomiasis mansoni in the two foci studied in Togo (Lama Kara in the North and Kpalimé in the South-West); however, the prevalence is significantly higher in Lama Kara (79.5%) than in Klonou (54.7%); this was calculated on both coprological and serological basis. The parasite burden is identical in the two foci; but, the GMRT is higher in Lama Kara than in Klonou (31.7 and 8) which might be explained by a different immunogenicity of the two strains. It is noticed schistosomiasis mansoni might be responsible for hepatosplenomegaly found in the two foci, especially in Lama Kara, which might be explained by a higher virulence in this location. The treatment by oltipraz (RP 35972) had a 91.9% success rate in Klonou (similar to our results in Paris). However, in Lama Kara, even though the drug was taken with some food--increasing its biodisponibility--, the treatment was less effective at day 180 (76.5%). The authors wonder whether the difference of oltipraz efficiency between the two foci is based on a difference of biology between the two strains of Schistosoma mansoni in Lama Kara and in Klonou.
