BACKGROUND Hypoglycaemia is an independent risk factor for death in severe malaria and a recognized adverse treatment effect of parenteral quinine. In 2006 our hospital changed quinine treatment policy from 15 mg/kg loading (plus 10 mg/kg 12-hourly) to 20 mg/kg loading (plus 10 mg/kg 8-hourly) to comply with new WHO guidelines. This presented us with the opportunity to examine whether there was...
THE following case history demonstrated several interestingpoints and for that reason is worth recording. The patient, Mrs. L., was a leading Wren aged 27 years, and was stationed at a Royal Naval Establishment on the east coast of C-eylon. She was married in June, 1944, and went up country for her honeymoon. Towards the end of this period, July 2, she developed general symptoms of malaise, fro...
The sensation of bitter substances can alert an animal that a specific type of food is harmful and should not be consumed. However, not all bitter compounds are equally toxic and some may even be beneficial in certain contexts. Thus, taste systems in general may have a broader range of functions than just in alerting the animal. In this study we investigate bitter sensing and processing in Dros...
BACKGROUND The mechanism of Plasmodium falciparum resistance to quinine is not known. In vitro quantitative trait loci mapping suggests involvement of a predicted P. falciparum sodium-hydrogen exchanger (pfnhe-1) on chromosome 13. METHODS We conducted prospective quinine efficacy studies in 2 villages, Kollé and Faladié, Mali. Cases of clinical malaria requiring intravenous therapy were treat...
1 mM caffeine, which produces only twitch potentiation and not contracture in frog sartorius muscle, increases both the uptake and release of (45)Ca in this muscle by about 50 %, thus acting like higher, contracture-producing concentrations but less intensely. Quinine increases the rate of release of (45)Ca from frog sartorius but not from the Achilles tendon. The thresholds for the quinine eff...
OBJECTIVES To monitor the sensitivity of Plasmodium falciparum to the drugs used to treat severe malaria and to prevent malaria in Comoros and Madagascar. DESIGN We used the in vitro isotopic method to test the sensitivity of P. falciparum to quinine, mefloquine and cycloguanil. RESULTS We tested fresh isolates of P. falciparum, collected from patients living in urban, suburban and rural ar...
Background: The capacity of human HbAA erythrocytes of non-malarious blood to withstand osmotic stress in the presence of five antimalarial drugs, Chloroquine phosphate, Quinine, FansidarTM, CoartemTM and HalfanTM was studied in vitro. Materials and Methods: Aqueous solutions of four increasing concentrations of the drugs used in this investigation were in the order: 0.2%, 0.4%, 0.6% and 0.8% (...
To determine if quinine has a metabolic effect during treatment of severe or complicated malaria, we studied its effects on plasma glucose and plasma insulin levels in 150 pregnant women with malaria referred to Madani maternity teaching hospital, Gezira state and 50 healthy pregnant controls. Levels were determined at baseline (day 0) before the start of quinine treatment, after 2 days of trea...
