Treatment of malaria in Vietnam with oral artemisinin.

In this study, 638 patients with either Plasmodium falciparum or P. vivax malaria were treated with artemisinin (qinghaosu) that was isolated and formulated into tablets and capsules in Vietnam. In all cases, artemisinin treatment resulted in a rapid clearance of parasitemia and fever. Recrudescence rates were highest in those groups receiving treatment for five or less days (50%), but were between 10% and 23% for those groups receiving the drug for 5-10 days. A low recrudescent rate (9.5%) was also found when patients were treated with a combination of artemisinin for three days and tetracycline for five days. Thus, artemisinin represents a useful and economically feasible component of the malaria control program in Vietnam.

Efficacy and effectiveness of five day treatment of uncomplicated falciparum with artemisinin or artesunate in Vietnam.

A study on efficacy and effectiveness of artemisinin (total dose of 60 mg/kg) and artesunate (total dose of 12 mg/kg over five days) in treatment of uncomplicated malaria was conducted in highly malaria transmitted areas in Vietnam. 126 uncomplicated malaria cases finished 14 day follow-up. 100% cure rate achieved at day 14 in patients of the efficacy groups received either artemisinin or artesunate, while it was 83% and 93% in patients treated respectively with artemisinin and artesunate of the effectiveness groups. Compliance of the treatment regimens was discussed.

[The effectiveness of tilmicosin in respiratory diseases of swine]. / Zur Wirksamkeit von Tilmicosin bei respiratorischen Erkrankungen des Schweines.

Within the scope of the clinical evaluation of Tilmicosin in Enzootic Pneumonia of pigs, nasal swabs from 78 animals were taken, before and after oral medication of different doses (0, 100, 200, 300 mg Tilmicosin/kg dry food), and examined bacteriologically for Pasteurella multocida, Bordetella bronchiseptica und Haemophilus parasuis. The bacteria aforementioned were isolated from the nasal secretions of 83% of the pigs, 14 days after crowding without any prophylactic regime. It could be demonstrated, that pigs with clinical symptoms of Enzootic Pneumonia had a 50% higher prevalence-rate of multi-colonization with pneumotropic bacteria than healthy animals. Feeding 300 mg Tilmicosin/kg food for 9 and 14 days respectively, resulted in elimination of Pasteurella spp. and Haemophilus spp. The rate of newly Bordetella bronchiseptica infected pigs was lower than in the placebo-group. Parallel to these bacteriological results improvement of clinical signs and increased daily weight gain were observed.
