Caspases as prognostic markers and mortality predictors in acute organophosphorus poisoning

Abstract

Organophosphorus (OP) compounds have been widely available for decades in agriculture for crop protection and as cheap pest controllers, which increases the rate of exposure and poisoning cases. Using serum cholinesterase as prognostic markers for the acute OP toxicity is controversial; therefore, we aim to find out prognostic biomarkers that best correlate with mortality and outcomes of patients with acute OP toxicity. Levels of serum oxidative stress biomarkers (malondialdehyde (MDA) and total antioxidant capacity (TAC)) and activity of the apoptotic biomarkers (caspase 3 and caspase 9) and pseudo-cholinesterase (p.ChE) were performed. Also, we evaluated the apoptotic capacity through determining the genotoxic effects and chromosomal abnormalities among OP intoxicated patients.
