ObjectivesTherapeutic plasma exchange is used to treat neurologic, hematological, renal, and autoimmune diseases with a known or suspected etiopathogenesis. However, there is incomplete understanding of the use of therapeutic plasma exchange in pediatric cases of intoxication. This study investigated 5 years of experience with therapeutic plasma exchange to treat intoxication cases.DesignA retrospective, case series, single-center study.SettingPICU of Baskent University, Dr. Turgut Noyan Teaching, and Medical Research Center Hospital in Adana, Turkey.PatientsFourteen patients diagnosed with intoxication who underwent therapeutic plasma exchange between January 2013 and January 2018.InterventionsNone.Measurements And Main ResultsData pertaining to 14 patients, including their medical history (exposure to drugs/toxicants), demographics, initial presentation, and severity of clinical symptoms (requirement of mechanical ventilation, Glasgow Coma Scale score, and the pediatric severity of illness score [Pediatric Logistic Organ Dysfunction] were retrospectively reviewed. The most common indication for therapeutic plasma exchange was multiple drug intoxication, followed by amitriptyline, Amanita phalloides mushroom, carbamazepine, mercury, verapamil, and botulism. All patients underwent therapeutic plasma exchange and two patients underwent hemodialysis before therapeutic plasma exchange. There was no mortality or complications related to the therapeutic plasma exchange procedure. Clinical improvement was observed after therapeutic plasma exchange in 13 of the 14 patients; one patient with verapamil intoxication died.ConclusionsTherapeutic plasma exchange appears to be safe and effective for treating pediatric cases of intoxication, including multidrug and amitriptyline intoxication, and is associated with significant recovery in the majority of severely affected patients. Treatment of intoxication with therapeutic plasma exchange should be guided primarily by the properties of the causative toxic substances/drugs, and consideration of patient age, the severity of clinical symptoms, Pediatric Logistic Organ Dysfunction score and response to initial supportive and antidotal treatment.
