Abstract

Highlights: We disclosed for the first time that the need of feeding support is significantly associated with assisted ventilation. Chinese MND patients may be more inclined to require respiratory support. Simultaneous degeneration of the bulbar and diaphragmatic muscles are often encountered in the late stages of Asian ALS patients. Abstract: Background : Motor neuron disease (MND) is a devastating degenerative disorder. Amyotrophic Lateral Sclerosis (ALS) is the most common and severe form of MND. Respiratory failure arising from ventilator musculature atrophy is the most common cause of death for ALS patients. Exploring the factors correlated with respiratory failure can contribute to disease management. Purpose : To characterize the clinical features of MND and determine the factors that may affect respiratory failure of MND patients. Methods : The case records of all MND patients seen in Singapore General Hospital (SGH) between January 2004 and December 2014 were examined. Demographic, clinical information were collected by reviewing case records. Mortality data, if not available from records, were obtained via phone call interview of family members. Demographic data and clinical treatments were compared between Respiratory support group and Non-respiratory support group. Results : There were 73 patients included in our study. 49 (67.1%) patients died during follow-up. The mean age of onset was 58 ± 11.1 years. With regard to treatment, 63% needed feeding support, and 42.5% required ventilation aid. The median overall survival was 36 months from symptom onset. Chi-square tests showed there was significantly higher percentage of respiratory support needed in Chinese than in other races ( P = 0.016). Compared with non-feeding support patients, patients with feeding support were more likely to require assisted ventilation ( P = 0.001). Conclusions : We report for the first time that the need of feeding support is significantly associated with assisted ventilation. Chinese MND patients may be more inclined to require respiratory support.
