Alteration in Liver Enzymes in Aluminum Phosphide Poisoning, A Retrospective Study

Abstract

Background: Aluminum phosphide (ALP) or rice tablet is a common agent used as pesticides. It is cheap, widely available and highly toxic and responsible for many cases of poisoning in the agricultural communities. There is limited evidence about change of liver enzymes in patients with ALP poisoning in this region. Therefore, we decided to evaluate alteration of liver enzymes in ALP poisoning in Rasht. Methods: In this retrospective cross-sectional study, all documents of patients with ALP poisoning admitted to Razi hospital of Rasht in 2008-2009 were assessed. Inclusion criteria were diagnostic clinical manifestation such as hypotension or metabolic acidosis, history of exposure to ALP during the past 24 hours and progressive signs and symptoms despite treatment (administration of sodium bicarbonate and vasopressor). Patients with past history of hepatic disease were excluded. Collected data were analyzed with SPSS software. Results: Of 104 patients with ALP poisoning, 66 patients (63.5%) were men. The mean age was 33.8±14.69 years, and the mean time of hospitalization was 14.94±18.28 hours. Ninety-five patients (91.3%) needed ventilation and 93 patients (89.4%) died. Statistical analysis demonstrated that elevated liver enzymes were not significantly related with gender, age, time of admission, time of hospitalization, the need for ventilation and mortality. Conclusion: It seems that liver enzymes changes is not seen widely in ALP poisoning and had lower importance than other complications. Because of limited studies in liver enzyme alterations in these patients, it is suggested that more studies with largee sample size is performed to investigate the ALP liver side effects
