Electrocardiographic abnormalities with quinine and artesunate combinations in comparison to quinine or artesunate alone in severe falciparum malaria

Anjali Tarai, Kali Prasad Pattnaik, Kumar Haraprasad Mishra

Abstract


Background: In Multi drug resistant falciparum malaria anti-malarial combinations are frequently used i.e. Quinine and IV Artesunate. Quinine is associated with electrocardiographic disturbances. Artesunate in high dose produce QTC prolongation in animal models, so the electrocardiogram (ECG) is thoroughly studied.

Methods: Severe falciparum malaria cases 15 to 60 years were randomly allocated into 3 treatment regimens i.e. Artesunate, Quinine alone and their combination. Electrocardiographic recordings were taken periodically in 3 groups and compared statistically.

Results: The mean QTC interval is significantly prolonged in combination treatment group from 0.40+0.02 to 0.49+0.09 (P<0.05) ECG disturbance (44%). QTC prolongation was commonest (i.e. 27%) with electrolyte imbalance could produce life threatening cardiac arrhythmia (Polymorphic VT with Sr K+ 2.9). Artesunate alone was list prone (i.e. only 6%) Quinine though has comparatively more (i.e. 25%) but there is no life-threatening cardiac arrhythmia in artesunate and Quinine.
