| Popis: | Cardio- and neurotoxicity of amphetamines play an important role in worsening morbidity, making the initial evaluation of the patient's status a potentially lifesaving action. The current study hypothesized that the S-100β serum level could predict the severity of acute amphetamine toxicity and the in-hospital outcome. The current study is a prospective cohort study conducted on 77 patients diagnosed with acute amphetamine exposure and referred to Aseer Poison Control Center, Saudi Arabia. The patients admitted to ICU showed significantly higher serum levels of S-100β in comparison to those not admitted (p 0.05). Moreover, the S-100β level was significantly elevated among patients with prolonged QTc intervals. Receiver-operating characteristic curve of S-100β serum level as an in-hospital outcome predictor showed that at a cutoff value 0.430 ug/L, the sensitivity of S-100β serum level as severity predictor was 100%, and the specificity was 74.1%. In conclusion, the current study revealed that the S-100β serum level could be used as an outcome predictor in hospital admission cases due to toxic amphetamine exposure and offers an idea about the cardiac and neuronal involvement. This can help select patients who will benefit most from ICU admission and early management and assess the severity of cases in settings where GC-MS is not available. |
