Background: Organophosphorus (OP) are substances that are originally produced by the reaction of alcohols and phosphoric acid. These OP compounds are the main components of herbicides, pesticides, and insecticides. These are easily available in developing country like India; there is lack of awareness about these chemicals which results in high morbidity and mortality. Aims and Objectives: To estimate levels of amylase, lipase, plasma cholinesterase in acute OP poisoning. To assess severity of OP poisoning by using plasma cholinesterase levels and correlating it with other two markers. Predicting the severity of acute OP poisoning by using these biochemical markers. Materials and Methods: A hospital-based observational study was conducted on 100 subjects who were clinically diagnosed of acute OP poisoning. Subjects of either gender of all age-groups were included in the study. On admission, plasma cholinesterase, serum amylase, and serum lipase were measured. Based on plasma cholinesterase activity at the time of admission, subjects were divided into three groups. Group I-having 20-50% of plasma cholinesterase activity; Group II-10-20% of plasma cholinesterase activity; and Group III <10% of plasma cholinesterase activity. Results: Among 100 patients it was seen that serum amylase and serum lipase were negatively correlated with plasma cholinesterase levels and it was statistically significant. It was seen that serum amylase had the highest diagnostic accuracy for assessing severity of poisoning, 10 deaths were there in which 6 had <10% of plasma cholinesterase activity, 8 out of these 10 patients had elevated amylase level. Conclusion: OP poisoning is associated with elevated amylase level. Serum amylase, lipase can be used as an additional prognostic indicator along with plasma cholinesterase levels. Serum amylase could be considered as a better predictor of severity than lipase.
