Abstract
Serum paraoxonase (PON1) is an esterase that is involved in the detoxification of organophosphate insecticides. Emerging lines of evidence have shown that functional polymorphisms in the PON1 gene might play a critical role in increasing susceptibility to organophosphate toxicity, but individually published studies showed inconclusive results. This meta-analysis aimed to derive a more precise estimation of the associations between the PON1 polymorphisms and organophosphate toxicity risk. Nine case-control studies were assessed with a total 1,042 patients with organophosphate toxicity and 1014 healthy controls. The meta-analysis results showed that the PON1 192Q and 55L polymorphisms may increase the risk of organophosphate toxicity. Further subgroup analyses by ethnicity showed significant associations of the PON1 192Q and 55L polymorphisms with increased risk of organophosphate toxicity among the Caucasian populations. However, similar associations were not observed among the Asian populations. In conclusion, the current meta-analysis indicates that the PON1 192Q and 55LM polymorphisms may increase the risk of organophosphate toxicity, especially among the Caucasian populations.
