Quinine is widely used for the treatment of severe and complicated malaria, although resistant strains of Plasmodium falciparum may occur. The drug has been incriminated as a cause of hypoglycaemia in some malaria patients. To determine if quinine has untoward metabolic effects during treatment of severe and complicated malaria we have studied the effects of quinine on blood glucose and intermediary metabolites, serum insulin, C-peptide, plasma glucagon and non-esterified fatty acids in 97 children with severe malaria in Dar es Salaam. All patients responded clinically. No patient developed hypoglycaemia while on quinine therapy given as 10 mg/kg in 10 ml/kg of 5% dextrose infused over 4 h every 8 h. Endogenous insulin secretion, as reflected by C-peptide levels, increased after 4 h but insulin levels did not change significantly. Blood lactate, 3-hydroxybutyrate, plasma non-esterified fatty acids and plasma glucagon all fell appropriately during treatment. We conclude that quinine, when administered at the recommended dose and rate, does not disrupt blood glucose homeostasis, and is still the drug of choice for severe and complicated malaria in children.

In an attempt to lower the mortality rate of neonatal tetanus a study was undertaken to determine whether intrathecal serotherapy influences mortality from this disease. Sixty-six babies with tetanus neonatorum were studied. The mortality rate among babies who received intrathecal anti-tetanus serum (ATS) was 45% compared with 82% in the control group given intramuscular ATS (P congruent to 0.002). Infants who received intrathecal ATS also had fewer complications than controls (P less than 0.001) and the duration of hospital stay for the survivors was 19.3 days compared with 28.7 days for the control group (P less than 0.05). It is concluded that intrathecal ATS is superior to intramuscular ATS in the treatment of neonatal tetanus.
