RESUMEN

Background: Amyotrophic lateral sclerosis (ALS) is a severe neurodegenerative disease. Given the inflammatory nature of ALS and the high number of ALS-related clinical circumstances (eg, prolonged immobilization and infections), patients with ALS may have a high risk of venous thromboembolism (VTE). Objectives: To determine the annual incidence rate of VTE and the predictors of VTE in patients with ALS. Methods: We analyzed a prospective cohort of patients with ALS diagnosed between 2009 and 2019 followed in the Brest University Hospital ALS Centre. Results: Among 227 patients with ALS, VTE occurred in 19 patients during a median follow-up period of 717 days (IQR, 488-1308), yielding an annual incidence rate of 2.93% (95% CI, 1.88%-4.53%). Predictors for VTE were a family history of VTE (hazard ratio [HR], 15.24; 95% CI, 1.72-134.84; P = .01), the presence of noninvasive ventilation at ALS diagnosis (HR, 6.98; 95% CI, 1.09-44.59; P = .04) and a short time (ie, <213 days) between first symptoms and ALS diagnosis (HR, 5.48; 95% CI, 1.57-19.11; P = .01). Recurrent VTE occurred within 3 months after stopping anticoagulation in 5 patients (26.3%). Conclusion: The annual incidence of VTE in patients with ALS is high. Predictive factors of VTE were a VTE history, noninvasive ventilation, and a short time between first symptoms of ALS and ALS diagnosis.

RESUMEN

BACKGROUND: Arterial puncture is often painful for patients. The aim of this study was to compare use of local anesthesia as a eutectic mixture of 2 local anesthetics, lidocaine and prilocaine, versus placebo. METHODS: We conducted a double-blind, randomized controlled trial. Subjects were eligible if arterial puncture was indicated. The primary outcome was an experienced pain > 2 on a numerical pain rating scale. As having had a previous experience of arterial puncture was expected to be predictive of the current response, we planned 3 comparisons between use of local anesthesia and placebo: in the whole sample, among subjects with a painful previous experience, and among subjects with a painless previous experience. Multiple testing was analyzed using the Bonferroni correction for the primary outcome. The secondary outcome was the numerical pain rating scale score itself. All analyses were performed on an intention-to-treat basis. RESULTS: A total of 136 subjects were included in this study. The primary outcome occurred in 20.9% in the active arm versus 37.7% in the placebo arm in the whole sample (relative risk 0.55; 95% CI when adjusting for multiple testing ranged was 0.28-1.09, P = .10; 95% CI without adjustment was 0.32-0.97, P = .038). No significant heterogeneity in the study treatment effect was found when considering previous painful or painless arterial puncture (P = .70). The numerical pain rating scale score was 1.55 ± 2.03 in active group versus 2.09 ± 2.15 in the placebo group (P = .13). CONCLUSIONS: We found that application of a eutectic mixture reduced the number of painful arterial punctures by 50% compared with placebo. However, this result was not statistically significant.
