An Outbreak of Synthetic Cannabinoid-Associated Coagulopathy in Illinois.
In March and April 2018, more than 150 patients presented to hospitals in Illinois with coagulopathy and bleeding diathesis. Area physicians and public health organizations identified an association between coagulopathy and synthetic cannabinoid use. Preliminary tests of patient serum samples and drug samples revealed that brodifacoum, an anticoagulant, was the likely adulterant.. We reviewed physician-reported data from patients admitted to Saint Francis Medical Center in Peoria, Illinois, between March 28 and April 21, 2018, and included in a case series adult patients who met the criteria used to diagnose synthetic cannabinoid-associated coagulopathy. A confirmatory anticoagulant poisoning panel was ordered at the discretion of the treating physician.. A total of 34 patients were identified as having synthetic cannabinoid-associated coagulopathy during 45 hospitalizations. Confirmatory anticoagulant testing was performed in 15 of the 34 patients, and superwarfarin poisoning was confirmed in the 15 patients tested. Anticoagulant tests were positive for brodifacoum in 15 patients (100%), difenacoum in 5 (33%), bromadiolone in 2 (13%), and warfarin in 1 (7%). Common symptoms at presentation included gross hematuria in 19 patients (56%) and abdominal pain in 16 (47%). Computed tomography was performed to evaluate abdominal pain and revealed renal abnormalities in 12 patients. Vitamin K. Our data indicate that superwarfarin adulterants of synthetic cannabinoids can lead to clinically significant coagulopathy. In our series, in most of the cases in which the patient presented with bleeding diathesis, symptoms were controlled with the use of vitamin K Topics: 4-Hydroxycoumarins; Abdominal Pain; Adult; Anticoagulants; Blood Coagulation Disorders; Blood Transfusion; Cannabinoids; Female; Hematuria; Hemorrhage; Humans; Illinois; International Normalized Ratio; Male; Middle Aged; Patient Readmission; Vitamin K; Warfarin | 2018 |
Superwarfarin poisoning and its management.
Difenacoum is a long-acting superwarfarin-type anticoagulant that exerts its effect through inhibiting vitamin K 2,3-epoxide reductase. Inhibition of this enzyme leads to reduced bioavailability of the metabolically active form of vitamin K resulting in decreased production of vitamin K-dependent proteins including coagulation factors II, VII, IX and X. A 45-year-old woman with psychiatric illness presented with haematuria. Laboratory test results indicated she had been exposed to a vitamin K antagonist which was subsequently identified as difenacoum. She was initially treated with phytomenadione, red cell suspension and octaplex. She was discharged on 30 mg phytomenadione daily but monitoring of vitamin K markers indicated that compliance was poor, and 152 days post-admission she presented with haemoptysis. Difenacoum and other superwarfarin rodenticides are freely available for purchase by the public. Cases such as this continue to raise issues about their availability and regulation.

Difenacoum poisoning as a cause of haematuria.
A man presented with frank haematuria and a grossly prolonged prothrombin time. He was later found to have taken an overdose of difenacoum--a 'superwarfarin' rodenticide. The diagnosis was confirmed by a serum concentration of difenacoum of 0.6 micrograms ml-1. Overdosage with superwarfarins is discussed and the need for prolonged treatment with vitamin K1 highlighted.
