Experience on loading dose--quinine therapy in cerebral malaria.
Twelve cases of cerebral malaria due to plasmodium falciparum, treated with loading dose of quinine (20 mg/kg salt in 500 ml of 5% glucose infused IV in 4 hrs) are compared with eleven age and sex matched cases treated with conventional dose of 10 mg/kg. The parasite clearance rate was significantly faster in loading dose group. There was no difference in recovery time: the interval between the initiation of treatment to full recovery of consciousness in both groups. One patient had pretreatment hypoglycaemia and two cases in the conventional dose group developed hypoglycaemia during therapy. One patient died in conventional dose group due to multi-organ failure. Two litres blood exchange transfusion was also tried for this case. Mild cinchonism occurred in two cases after loading dose while this was observed only in one case in conventional dose group. There was no significant hypotension or ECG changes in any patient. Loading dose of quinine seems to be well tolerated and may clear parasitaemia faster in case of malaria due to Plasmodium falciparum (PF).
