[Complicated malaria tropica: specific and supportive therapy in the imported diseases].

Eleven of 43 nonimmune patients with falciparum malaria had one or several organ complications: cerebral malaria, acute respiratory failure, acute renal failure, secondary infection, autoimmune haemolysis, spontaneous spleen rupture, and acute pancreatitis. Parasitaemia was 0.1 to 60%. Initial antiparasitic therapy with quinine given parenterally resulted in rapid regression of parasitaemia. An additional schizonticide agent was given depending on parasitic resistance. Supportive therapy comprised intensive-care monitoring including fluid and electrolyte balance and, if necessary, early haemodialysis and (or) endotracheal intubation with PEEP breathing. In one patient with excessive parasitaemia exchange transfusion was performed. Heparin was given only in proven disseminated intravascular coagulation, corticosteroids only in persistent autoimmune haemolysis. All patients survived without suffering permanent defects. Retrospective analysis shows that, apart from rapid specific therapy, supportive treatment of the individual organ complications determines course and prognosis of complicated falciparum malaria.

Evaluation of antigens for the serodiagnosis of kala-azar and oriental sores by means of the indirect immunofluorescence antibody test (IFAT).

Antigens and corresponding sera were collected from travellers with leishmaniasis returning to Germany from different endemic areas of the old world. The antigenicity of these Leishmania strains, which were maintained in Syrian hamsters, was compared by indirect immunofluorescence (IFAT). Antigenicity was demonstrated by antibody titres in 18 sera from 11 patients. The amastigotic stages of nine strains of Leishmania donovani and four strains of Leishmania tropica were compared with each other and with the culture forms of insect flagellates (Strigomonas oncopelti and Leptomonas ctenocephali). Eighteen sera from 11 patients were available for antibody determination with these antigens. The maximal antibody titres in a single serum varied considerably depending on which antigen was used for the test. High antibody levels could only be maintained when Leishmania donovani was employed as the antigen, but considerable differences also occurred between the different strains of this species. The other antigens were weaker. No differences in antigenicity between amastigotes and promastigotes of the same strain were observed. It is important to select suitable antigens. Low titres may be of doubtful specificity and are a poor baseline for the fall in titre which is an essential index of effective treatment.

Praziquantel in clonorchiasis and opisthorchiasis.

A single stool examination revealed pathogenic intestinal parasites in 462 (58%) of 796 vietnamese and cambodian refugees. 56 (7.0%) were infected with Clonorchis sinensis and/or Opisthorchis viverrini. These patients received Praziquantel in a dosage of 20 mg/kg bwt. p.day on 3 consecutive days. Parasitological controls were completed after 12 months. No further excretion of eggs could be detected in 88% of the patients. Concurrent infections with other trematodes and cestodes were also cured. Nematode infections remained uninfluenced. No change of haematological and biochemical parameters could be observed during therapy. Diarrhea and epigastric pain were common side effects, which are probably not effects of the drug itself. They rather seem to be due to the release of parasitic antigens. This is also indicated by a further increase of circulating Ig E after therapy.

[The diagnosis of visceral leishmaniasis (carried in) (author's transl)].

Five cases of Kala-Azar carried in from the Mediterranean area between May 1977 and March 1979 suggest that in this age of mass tourism these diseases, considered by us as rarities until now, may become more common. In all cases considerable difficulties in diagnosis were first encountered. Serology was always indicative, the indirect fluorescence antibody test (IFAT) being found very reliable. In 4 of the 5 cases the identity of the pathogen was previously established by different methods.
