RESUMO
BACKGROUND: Macroglossia is one of the clinical signs that emerges in patients with amyotrophic lateral sclerosis (ALS) who are undergoing invasive ventilation. OBJECTIVE: We aimed to investigate the relationship between the progression of macroglossia and the clinical characteristics during the advanced stages of ALS. METHODS: Forty-one patients with ALS using invasive ventilation with tracheostomy were prospectively followed over a 3-year period. We evaluated the prevalence of macroglossia, motor disabilities including oral function, communication ability (communication stage I to V) as a marker of disease progression, and nutritional factors. We analyzed the potential factors affecting the progression of macroglossia using a multivariate logistic analysis. RESULTS: The number of patients with macroglossia was increased during the follow-up (from 24.4 to 53.7%), while the communication stage progressed from 2.6 in average (SD 1.7) to 3.5 (1.4). During the study, body weight increased, while energy intake decreased, suggesting progressive hypometabolism. Eight patients had newly developed macroglossia during the study and showed greater progression of communication impairment than those without macroglossia. Multivariate logistic regression analysis showed that communication impairment was a factor associated with macroglossia. CONCLUSION: Macroglossia in advanced ALS with invasive ventilation is associated with disease progression.

Patients with amyotrophic lateral sclerosis (ALS) often suffer from salivation problems such as drooling and dry mouth. We examined resting salivation rate cross-sectionally in 66 advanced ALS patients with tracheostomy invasive ventilation using a cotton roll method, and investigated clinical factors associated with salivation rate. Resting salivation rate in the patients was well preserved (median value 0.6â g/min), and was significantly more increased in patients with impairment of jaw movement (P = 0.007) or mouth opening (P = 0.003) than in patients with less impairment, and in patients with the mouth being constantly open ≥ 10â mm in rostrocaudal length than in patients with < 10â mm. These data indicate that salivation rate was increased with progression of dysfunction of voluntary jaw movement. Appropriate oral care is required in advanced ALS patients to maintain their oral hygiene and to avoid penetration of saliva into the airway.

INTRODUCTION: An enlarged tongue (macroglossia) has been reported in advanced-stage patients with amyotrophic lateral sclerosis (ALS). METHODS: In this study we examined the prevalence of macroglossia and analyzed clinical correlations in 65 ALS patients on tracheostomy-invasive ventilation (TIV). RESULTS: Macroglossia was found in 22 patients (33.8%). Compared with those without macroglossia, patients with macroglossia had a younger age of onset, longer duration of disease and TIV use, lower ALS Functional Rating Scale score, higher body mass index, lower energy intake, more severe communication impairment, and lower oral function. Logistic multivariate analysis showed that body mass index (BMI; P = 0.007) and communication impairment (P = 0.029) were significantly correlated with macroglossia. The duration of TIV use was at the cut-off level of significance (P = 0.05). CONCLUSIONS: Macroglossia may be the result of overfeeding and replacement by fat during long-term TIV use in patients with advanced ALS. Muscle Nerve, 2016 Muscle Nerve 54: 386-390, 2016.
