脊髓灰质炎后综合征的概念及病理生理机制

摘要

脊髓灰质炎后综合征(PPS)是患者急性感染脊髓灰质炎病毒,经过后遗症期后新发生的综合征.PPS发病率高,老年患者越来越多.PPS患者有累及肌肉的慢性神经源性损害,导致疲劳、疼痛、呼吸和睡眠障碍以及跌倒风险等,严重时影响健康状况和生活质量.PPS的发病机制有运动神经元过度负荷学说、脊髓灰质炎病毒持续存在学说等.PPS是一种相对稳定、缓慢进展的神经肌肉疾病.%Post-polio syndrome (PPS) is a syndrome after acute infection of poliovirus and sequelae of polio. The incidence of PPS is high, and more in old patients. The pathological features of PPS include chronic nerve damage affected muscles, result in fatigue, pain, breathing and sleep disorders, fall risk, and so on, which impair their health and quality of life. The hypotheses of pathogenesis of PPS in-clude over load of motor neurons, and the continuous existence of the poliovirus, etc. PPS is a stable neuromuscular disease progressing slowly.
