[Observation on efficacy of artemether compound against vivax malaria].

AIM
To observe the efficacy of artemether compound against vivax malaria.


METHODS
Each artemether compound tablet contains 120 mg benflumetolum and 20 mg artemether. 132 patients with vivax malaria were divided into 3 groups. Group A, 36 patients received 8 tablets as an initial dose, followed by 4 tablets daily for 2 days; group B, 41 patients received 8 tablets as an initial dose, followed by 3 tablets daily for 4 days; group C, 55 patients receiving chloroguine-primaquine served as control. Two patients of group A were voluntarily to be bitten by Anopheles dirus before and after medication to observe the influence of artemether compound on the sporogony.


RESULTS
The average defervescence times for groups A, B and C were 22.3 h, 23.2 h and 25.0 h (P > 0.05), respectively, the average parasite clearance times were 33.5 h, 30.5 h and 44.9 h, respectively, the average parasite clearance times of groups A and B were all significantly shorter than that of group C (P < 0.01). The replase rates of groups A, B and C were 84.9%, 78.8% and 22.9%, respectively, followed-up at nine months, the relapse rates of groups A and B were higher than that of group C(P < 0.01).


CONCLUSION
Two regimens of artemether compound have the advantage of high efficacy against vivax malaria.
