RESUMO
The association of neuromyelitis optica concurrently with two other autoimmune diseases is rare. Neuromyelitis optica should be taken into consideration when evaluating the symptoms of the patient as a differential diagnostic aspect.
RESUMO
BACKGROUND: Intravenous thrombolysis (IVT) improves acute ischemic stroke (AIS) outcomes, but with limited success. In addition, ethanol potentiates the effect of r-tPA in ischemia models. METHODS: The effect of acute alcohol consumption on IVT outcomes was investigated in a retrospective cohort study. AIS patients with detectable blood alcohol concentration (BAC) during IVT were included (alcohol group; n = 60). For each case, 3 control subjects who underwent IVT but denied alcohol consumption were matched in terms of age, sex, affected brain area, and stroke severity. Outcomes were determined using the NIHSS at 7 days and the modified Rankin scale (mRS) at 90 days. RESULTS: Patients were younger and had a less severe stroke than in a standard stroke study. Favorable long-term outcomes (mRS 0-2) occurred significantly more frequently in the alcohol group compared to controls (90% vs. 63%, p < 0.001). However, the rates of hemorrhagic transformation were similar. Multiple logistic regression models identified elevated BAC as a significant protective factor against unfavorable short-term (OR: 0.091, 95% CI: 0.036-0.227, p < 0.001) and long-term outcomes (OR: 0.187, 95% CI: 0.066-0.535, p = 0.002). In patients with BAC > 0.2%, significantly lower NIHSS was observed at 3 and 7 days after IVT vs. in those with 0.01-0.2% ethanol levels. CONCLUSION: Elevated BAC is associated with improved outcomes in IVT-treated AIS without affecting safety.
