ABSTRACT
Interleukin-10 (IL-10) is an important cytokine in the down-regulation of inflammatory responses, and it has been reported that a low plasma concentration of IL-10 is associated with severe anemia and cerebral malaria in Plasmodium falciparum infections. The IL-10 gene is located on chromosome 1q31-32, and a promoter polymorphism (-1082G/A) is known to affect IL-10 protein production. In order to examine the possible association of the -1082G/A polymorphism with the severity of malaria, we studied 203 mild malaria, 164 non-cerebral severe malaria, and 109 cerebral malaria patients living in northwest Thailand. The genotyping was performed by a fluorescence resonance energy transfer (FRET) method. The frequencies of a major allele -1082A in mild malaria, in non-cerebral severe malaria, and in cerebral malaria patients were 92.6%, 92.1%, and 92.7% respectively. Our results showed no significant association of the -1082G/A polymorphism with the severity of malaria.
