Serum cholinesterase activity in patients with malaria infection.

ABSTRACT

Serum cholinesterase activities were determined in 87 patients of both sexes with P. falciparum malaria in comparison to those of 80 blood donors. Patients with acute P. falciparum malaria had significantly lower serum cholinesterase activity than those of the control group. After treatment, their serum cholinesterase levels returned to the normal level. Serum albumin concentration also showed the same pattern and had a direct relationship to those of serum cholinesterase levels. These findings indicated that malarial parasites had some effect on the liver cells which resulted in impaired hepatic synthesis of serum cholinesterase and albumin concentrations. This result therefore add new information that there was a disturbance of enzyme cholinesterase among many liver enzymes that have been shown to be altered during an acute malarial attack.
