Clinical analysis of 48 patients with acute mushroom poisoning / 中华危重病急救医学

ABSTRACT

Objective To analyze the clinical manifestation and therapeutic method in patients with acute mushroom poisoning. Methods A retrospective study was conducted. The clinical data of 48 patients with acute mushroom poisoning admitted to Department of Poisoning Treatment of the 307th Hospital of PLA from January 2016 to May 2017 were analyzed. The clinical data including gender, age, clinical symptoms, onset season, initial symptoms, incubation time, the length of hospital stay, treatment, and prognosis. In addition to the conventional treatment, the patients with severe liver damage were treated with continuous blood purification (CBP). The changes in routine blood test, biochemical parameters, blood ammonia and coagulation function before and 1, 3 and 7 days after CBP were observed. Results There were 29 of male (60.4%) and 19 of female (39.6%) in 48 patients with acute mushroom poisoning, with an average age of (48.10±13.14) years. There were 9 patients suffering from gastroenteritis type, 26 suffering from liver damage type, 8 suffering from neuro-psychosis type, 2 suffering from hemolytic type, and 3 suffering from renal damage type. All of the poisoned patients had evident seasonal characteristic, mainly concentrated in the autumn, especially in August, according for 66.7% (32/48). The initial symptoms of poisoning patients were mainly manifested as nausea and vomiting (50.0%). In five kinds of poisoned patients, the incubation time [(1.44±1.15) hours] and the length of hospital stay [(3.50±2.33) days] of neuro-psychosis type was the shortest, and the incubation time of liver-damaged type [(10.63±3.50) hours] and the length of hospital stay of renal damage type [(20.67±0.58) days] was the longest. Patients received symptomatic treatment according to different types, among whom 12 patients with severe liver damage received additional treatment for CBP. After the treatment, alanine aminotransferase (ALT), aspartate aminotransferase (AST), MB isoenzyme of creatine kinase (CK-MB), lactate dehydrogenase (LDH), and prothrombin activity (PTA) were significantly improved as compared with those before CBP treatment, with significant differences between 7 days after CBP and before CBP [ALT (U/L) 213.08±127.30 vs. 2 766.83±1 909.66, AST (U/L) 50.00 (41.00, 85.00) vs. 2 142.00 (1 225.00, 3 126.00), CK-MB (U/L) 24.09±8.87 vs. 44.75±22.09, LDH (μmol·s-1·L-1)3.70±1.46 vs. 13.03±12.77, PTA (79.08±24.29)% vs. (35.25±19.85)%, all P < 0.01]. Among 48 patients, 47 were cured and discharged, and 1 patient with liver failure died due to aggravation of liver dysfunction, abnormal coagulation and bleeding, and massive hemorrhage of gastrointestinal tract. Conclusions Acute mushroom poisoning patients demonstrated obvious seasonal characteristics, mostly liver-damaged type, and its initial symptoms were mainly presented as nausea, vomiting and other gastrointestinal manifestations. Early clarification of diagnosis, timely treatment, as well as providence with CBP treatment in severe patients should be carried out as soon as possible. In such a way the curative effect can be enhanced, the mortality can be reduced, and the prognosis of the patients could be improved.
