Possible central role of nitric oxide in conditions clinically similar to cerebral malaria
The changes in mental status during cerebral malaria, heat stroke, and recovery from major surgery are clinically similar, and are associated with high circulating concentrations of cytokines that can induce nitric oxide generation in vascular walls. This vascular nitric oxide could diffuse across t...

| description | The changes in mental status during cerebral malaria, heat stroke, and recovery from major surgery are clinically similar, and are associated with high circulating concentrations of cytokines that can induce nitric oxide generation in vascular walls. This vascular nitric oxide could diffuse across the bloodbrain barrier, causing functional changes that include inhibition of glutamate-induced calcium entry, reduced activity of the calcium-dependent nitric oxide synthase, and thus reduced nitric oxide formation, in post-synaptic neurons. Certain general anaesthetics and ethanol reduce glutamate-induced calcium entry into post-synaptic cells, and so would also reduce the rate of formation of neuronal nitric oxide. In view of the apparent importance of glutamate-induced nitric oxide in excitatory neurotransmission, a reduction in neuronal nitric oxide could help explain why these otherwise unrelated influences alter central nervous system function in a similar manner. In particular, this reduction could rationalise why heat stroke, ethanol excess, morphine poisoning, and conditions with high blood ammonia concentrations are easily confused clinically with cerebral malaria. |
