AIM To identify early predictive markers of poor outcomes in patients with acute liver injury from wild mushroom intoxication.METHODS This observational, retrospective record review involved adults aged ≥ 18 years admitted to emergency department with mushroom intoxication from January 2005 to December 2015. The diagnosis of mushroom intoxication was based on the following:(1) a positive history of recent wild mushroom intake(either raw or cooked);(2) the onset of gastrointestinal symptoms, such as watery diarrhea, vomiting, and/or abdominal pain, after ingestion; and(3) the exclusion of other possible causes of acute liver injury. Acute liver injury was defined by a > 5-fold elevation of liver enzymes or moderate coagulopathy [international normalized ratio(INR) > 2.0]. Clinical and laboratory findings were compared in survivors and non-survivors.RESULTS Of 93 patients with mushroom intoxication, 23, 11 men(47.8%) and 12 women(52.2%), of median age 61 years, developed acute liver injury. The overall inhospital mortality rate was 43.5%(10/23). Among thelaboratory variables, mean serum alkaline phosphatase(73.38 ± 10.89 mg/dL vs 180.40 ± 65.39 mg/dL, P < 0.01), total bilirubin(2.312 ± 1.16 mg/dL vs 7.16 ± 2.94 mg/d L, P < 0.01) concentrations and indirect/direct bilirubin(2.45 ± 1.39 mg/dL vs 0.99 ± 0.45 mg/dL, P < 0.01) ratio as well as prothrombin time(1.88 ± 0.83 mg/dL vs 10.43 ± 4.81 mg/dL, P < 0.01), and activated partial thromboplastin time(a PTT; 32.48 ± 7.64 s vs 72.58 ± 41.29 s, P = 0.01), were significantly higher in non-survivors than in survivors. Logistic regression analysis showed that total bilirubin concentration(OR = 3.58, 95%CI: 1.25-10.22), indirect/direct bilirubin ratio(OR = 0.14, 95%CI: 0.02-0.94) and aP TT(OR = 1.30, 95%CI: 1.04-1.63) were significantly associated with mortality. All patients with total bilirubin > 5 mg/dL or aP TT > 50 s on day 3 died.CONCLUSION Monitoring of bilirubin concentrations and a PTT may help in predicting clinical outcomes in patients with acute liver injury from wild mushroom intoxication.
