Background: Several studies have shown that high-density lipoprotein (HDL) cholesterol provides protection against bacterial infections. Our aim was to investigate the influence of HDL cholesterol levels on the risk of developing in-hospital infectious complications after an acute ischemic stroke (IS) as well as the possible effect of prestroke statin treatment on this association. Methods and Results: Observational study that included consecutive IS patients during a 5-year period (2006-2010). We analyzed vascular risk factors, prestroke treatments (including statins), laboratory data (including HDL cholesterol levels), stroke severity, and the development of infectious complications (pneumonia, urinary tract infection and sepsis). A multivariate analysis that included HDL cholesterol levels, prior statin treatment and the interaction between both variables was performed to identify those factors associated with the presence of infectious complications. A total of 1,385 patients were included, 130 of whom (9.4%) developed in-hospital infections. The receiver operating characteristic curve showed the predictive value of HDL cholesterol with an area under the curve of 0.597 (95% CI, 0.526-0.668; p = 0.006) and pointed to 38.5 mg/dl of HDL cholesterol (65.5% sensitivity and 53.4% specificity) as the optimal cutoff level for developing infectious complications during hospitalization. An HDL cholesterol level ≥38.5 mg/dl was an independent predictive factor for lower risk of infection (OR 0.308; 95% CI 0.119-0.795), whereas prestroke statin treatment was not associated with the development of infection. Conclusions: An HDL cholesterol level ≥38.5 mg/dl was independently associated with lower risk for developing infectious complications in acute IS patients. Statins do not influence this association.
In young stroke patients with APS, serum levels of IgM aCL within 48 h are correlated with stroke severity and levels of IgG anti-β2GPI within 48 h are correlated with three-month outcomes.
The benefit of intravenous thrombolysis (IVT) has been questioned for patients with diabetes mellitus (DM) in cases of acute ischemic stroke (IS). Our objective was to analyze the differences in outcome according to prior diagnosis of DM and the use or not of IVT. Observational study with inclusion of consecutive IS patients admitted to an stroke unit. Demographic data, vascular risk factors, comorbidity, stroke severity and 3-month follow-up outcome (modified Rankin Scale) were compared according to prior diagnosis of DM and the use or not of IVT. A total of 1,139 IS patients were admitted; 283 (24.8%) patients had a diagnosis of DM, and 261 were IVT treated (23.2% of the group without DM and 21.9% of the DM group). The IVT-treated patients with DM were older, had more comorbidities and had higher glucose levels on admission than those without DM and than IVT-treated patients. No significant differences in stroke severity, hemorrhagic transformation, in-hospital mortality or outcome at 3 months were found. The logistic regression analysis showed that stroke severity was associated with a higher risk of a poor outcome in IVT-treated patients, with no significant effect from DM after adjustment for confounders. Moreover, IVT was independently associated with a lower risk of poor outcome in DM patients (OR 0.49; 95% CI 0.31-0.76; P = .002). DM patients should not be excluded from IVT, because DM is not associated with a poor outcome after IVT and this treatment is clearly beneficial for DM patients as compared with DM patients not treated with IVT.
The effect of intravenous thrombolysis (IVT) according to etiology and stroke severity in young patients with ischemic stroke (IS) has not been described previously. To analyze the effect of IVT in young patients with IS according to etiological subtype and stroke severity. Observational study with inclusion of IS patients under 55 years of age (2007-2012). Two groups were compared according to IVT treatment. Favorable outcomes were defined as 3 months modified Rankin Scale ≤2. Multivariate analyses were performed to determine those factors independently associated with favorable outcomes, and subgroup analyses were conducted to assess the effect of IVT according to etiological stroke subtype and severity on admission, adjusted for other prognostic variables. We evaluated 262 patients. 63 (24%) received IVT. The mean age and the sex distribution were similar in the IVT treated and the non-treated groups. Multivariate analyses showed that IVT was associated with a higher probability of favorable outcome (OR, 95% CI: 4.652, 1.294-16.722) whereas artery dissection (OR, 95% CI: 0.191, 0.056-0.654) and NIHSS (OR, 95% CI: 0.727, 0.664-0.797) were associated with a lower probability of a favorable outcome. The subgroup analysis showed that the beneficial effect of IVT on outcomes was significant in moderate-severe strokes (NIHSS ≥8) (OR, 95% CI: 3.782, 1.095-13.069) and in cardioembolism (OR, 95% CI: 41.887, 1.001-1751.596). In IS patients under 55 years of age, those with moderate-severe strokes benefit more from IVT than those with mild strokes. Cardioembolic infarctions may benefit more from IV tPA than other etiologies.
Blepharospasm (BPS) is one of the most frequent types of facial dystonia and, at the same time, one of the most disabling, being able to trigger functional blindness if not treated. Our aim with this work was to evaluate the efficacy and safety of long-term onabotulinum A toxin (BAT) treatment in a cohort of patients with BPS. The retrospective study was conducted on consecutive patients with BPS treated with subcutaneous BAT. The selection of muscles and dose was made based on each patient's needs. The clinical and demographic characteristics, number of sessions, dose, duration and effectiveness of treatment, and adverse events were analysed. 130 patients were included in the study. The median (95% confidence interval) length of follow-up was 14 (13-15.6) years with an average of 20.5 sessions (range from 10 to 57). Regarding the efficacy of the treatment, 114 (87.7%) experienced satisfactory results with functional and aesthetics recovery. Patient evaluation of global response suggested a clear improvement without adverse events in 72 (55.4%) patients. Adverse events developed at least once during the treatment in 39% of patients, with transient ptosis and haematoma the most common reported both by physician and patient. The results of our study suggest that botulin toxin A is a safe and effective long-term treatment for blepharospasm with mild, transient and well-tolerated side effects when they appear.
