Abstract
Objective This study was conducted to determine whether longer lifespans in African Americans with amyotrophic lateral sclerosis (ALS), compared to white non-Hispanics, are secondary to higher rates of tracheostomy and invasive ventilation (TIV) in African Americans.
Methods A retrospective case-control study was conducted with 49 African Americans with ALS matched by age, gender, and site of onset to 137 white persons with ALS.
Results African Americans had longer survival than whites when the outcome was death (p = 0.016), but this was no longer significant when the outcome was death or TIV (p = 0.100). African Americans also had a lower rate of noninvasive ventilation use compared to whites (27 [55%] vs 96 [70%], p = 0.015) and a higher rate of TIV (8 [16%] vs 7 [5%], p = 0.016), but after controlling for baseline severity, only the noninvasive ventilation difference (p = 0.036), and not the TIV difference (p = 0.115), remained significant.
Conclusion African Americans with ALS live longer than white persons with ALS, and this may be secondary to higher rates of TIV use among African Americans.
