Venous diethylene glycol poisoning in patients with preexisting severe liver disease:a clinical analysis / 中华传染病杂志

ABSTRACT

Objective To describe the clinical features of venous diethylene glycol poisoning and to identify factors correlating with such kind of poisoning.Methods Retrospective chart review was performed to analyze the epidemiology,clinical presentation,hepatorenal functions,bemodynam- ics and pathological characteristics of 64 patients with severe liver diseases who received intravenous diethylene glycol.Comparative analyses of correlating factors and causes of poisoning were based on the presence or absence of poisoning.Results Fifteen cases of poisoning were reported.After a 5 day incubation period,all poisoned patients displayed acute renal failure and 11 cases with digestive tract symptoms and(or) symptom exacerbations were noted.Neurological system impairment was observed in 10 cases after 2 weeks.Metabolic acidosis developed in 13 cases.Poisoned patients exhibited signif- icantly lower red blood celI(RBC)[(2.32?0.76)?10~(12)/L],hemoglobin(Hb) [(79.5?23.6)g/L] value and higher white blood cell(WBC)[(9.78?3.75)?10~9/L] count.Renal biopsy of poisoned patients revealed acute tubular necrosis and interstitial nephritis.Twelve poisoned patients died.Sig nifieant differences were found between groups regarding preexisting severe hepatitis,ascites,renal disease and diuretic therapy.Prior to diethylene glycol injections,mean values of neutrophil,blood urea nitrogen(BUN),creatinine(Cr) and calcium and phosphorousions differed significantly between groups.Conclusions Features of venous diethylene glycol poisoning include oliguric acute renal fail- ure,metabolic acidosis,digestive symptoms,nervous system impairment and a high probability of anemia and WBC proliferation.Mortality is high.Correlative factors include preexisting severe liver disease,renal disease and infection.
