TY - JOUR PY - 2011// TI - Laboratory investigations in acute olanzapine poisonings JO - Przeglad Lekarski A1 - Ciszowski, Krzysztof A1 - Sein Anand, Jacek A1 - Wilimowska, Jolanta A1 - Jawień, Wojciech SP - 417 EP - 421 VL - 68 IS - 8 N2 - BACKGROUND: Olanzapine is an atypical antipsychotic with multireceptor affinity and different pharmacological effects, which can result with abnormalities in laboratory investigations. AIM OF THE STUDY: To assess the nature and frequency of laboratory tests abnormalities in patients with an acute olanzapine poisoning. Material: 26 adult cases (mean age 37.7 +/- 15.3 years) of an acute olanzapine poisoning (serum level above 100 ng/mL). Group consisted of 11 men and 13 women, but 1 man and 1 woman were poisoned twice. METHODS: Prospective analysis of the following laboratory parameters: complete blood count (CBC), coagulation tests (APTT, INR), serum concentration of sodium, potassium, chlorides, glucose, BUN, creatinine and bilirubin, serum activity of AST, ALT, GGTP and CPK, urinalysis. RESULTS: The most common laboratory abnormalities in the study group were: hyperglycaemia (96%), hyper-prolactinaemia (83%), elevated CPK (80%), hypokalaemia (75%), hyperbilirubinaemia (60%), leukocytosis (55%). Less frequent parameters were: elevated AST (20%), hyponatraemia (15%), elevated ALT(10%) and thrombocytopenia (5%). The onset of some parameters was as follows: 1st day of hospitalization hyperglycaemia, leukocytosis and hypokalaemia, 2nd - hyperbilirubinaemia and elevated CPK, and 3rd - hyperprolactinaemia. CONCLUSIONS: In acute olanzapine poisonings: (1) muscle and liver injury, serum glucose and electrolytes abnormalities, and changes in CBC can be present; (2) the valuable parameters for the monitoring of the course of poisonings are: serum activity of CPK and transaminases (AST, ALT), serum level of bilirubin, glucose, potassium and sodium, and CBC; (3) hyperprolactinaemia probably lacks of practical importance, but the further investigations are needed in this area.
