Clinical analysis of 156 cases of multiple organ failure caused by fish bile

OBJECTIVE: To analyze the clinical features and prognosis of patients suffering from fish bile poisoning. METHODS: A total of 156 multiple organ failure (MOF) patients caused by fish bile poisoning were hospitalized in our department over the past 28 years. The patients’ symptoms, examination results, treatment and outcomes were collected and analyzed. RESULTS: All patients’ first symptom was gastrointestinal discomfort, including unbearable nausea and intractable vomiting. The symptoms that followed were oliguria or anuria, edema, headache, fatigue, jaundice, palpitation, alimentary tract hemorrhage, gross hematuria, dyspnea, shock, tachycardia, bradycardia, arrhythmia, coma, and cardiac arrest. The symptom severity and cohort were different among different patients. Twenty-one cases received gastroscopy, which exhibited diffuse gastric mucosal bleeding. Twelve patients received renal biopsy, which exhibited focal necrosis of tubular epithelial cells. One patient received a liver biopsy, which exhibited extensive hepatocyte necrosis. All patients received blood purification therapy. Of the four patients who died, 4 out of 5 organs had failed. The general mortality rate was 2.6%. CONCLUSIONS: Compared with the MOF caused by trauma and sepsis, the fish bile poisoning MOF has a much lower morality rate. However, patients with higher age, more underlying diseases, and more organ failure tended to have a worse prognosis.
