ANNEX 8. Treatment of severe Plasmodium falciparum malaria



           a8.1  Question:
                 Is artesunate superior to quinine in treating severe malaria?




           Background
           Artesunate was recommended as an alternative to quinine for treating severe malaria in
           the first edition of the WHO guidelines for the treatment of malaria.

           GraDE approach

           Artesunate was compared to quinine using meta-analyses of head-to-head RCTs (search
           date: January 2007).
           1.  Is artesunate superior to quinine in treating severe malaria? (See GRADE Table
             A8.1.)



           When assessing this evidence the WHO GRADE panel considered the following factors
           to be important:
           •  all six studies included in the review were conducted in Asia;
           •  one large trial enrolling both adults and children provides most of the data but
             outcomes were not reported separately for children;
           •  most deaths from severe malaria occur in African children;
           •  children present with a different picture of severe malaria compared to adults;

           •  five trials used intravenous artesunate and one trial used intramuscular artesunate.

           Other considerations
           In contrast to quinine, administration of artesunate does not require cardiac monitoring
           and, therefore, may be a more practical option in resource-poor settings.
                                                                                       A8
            Decision

            On the basis of these tables, the WHO GRADE panel made a strong recommendation
            that artesunate should be used in preference to quinine for the treatment of severe
            malaria in Asia.
