        There are few data devoted to the combined assessment of the nutritional and respiratory status of subjects with neuromuscular diseases. The objective was to establish correlations between compartmental nutritional variables and respiratory variables to identify respiratory muscle weakness determinants of patients with amyotrophic lateral sclerosis (ALS) and Duchenne muscular dystrophy (DMD). Cross-sectional study with ALS and DMD patients included in an Institutional Registry of Neuromuscular diseases. Nutritional status was assessed through body mass index (BMI), expected weight for zero muscle mass (ZMM%) and creatinine-height index (CHI%). Respiratory indices evaluated were spirometry, maximal static inspiratory and expiratory pressures at the mouth (MIP and MEP), and peak cough flow (PCF). A total of 36 ALS and 34 DMD patients were included. Both groups showed a decrease in the body muscle mass and an excess in body fat (p < 0.001). Only in the ALS group was there a weak uphill relationship between body mass index (BMI) and the respiratory variables. In both groups, the ZMM% index did not correlate with any respiratory variable. The CHI% showed the strongest (r > 0.700) positive linear relationship with FVC%, MIP%, MEP%, and PCF% in both ALS and DMD patients (p < 0.001).In this study our patients, BMI did not accurately reflect body composition and underestimated excess fat. This study puts into perspective the relevance of compartmental evaluation to assess respiratory muscle function and establishes that body muscle mass is the most relevant nutritional parameter in relation to respiratory muscle strength.
        Hay pocos datos relativos a la evaluación combinada del estado nutricional y respiratorio de sujetos con enfermedades neuromusculares. El objetivo fue establecer correlaciones entre las variables nutricionales compartimentales y las variables respiratorias para identificar los determinantes de la debilidad de los músculos respiratorios de los pacientes con esclerosis lateral amiotrófica (ELA) y distrofia muscular de Duchenne (DMD). Estudio transversal con pacientes con ELA y DMD incluidos en el Registro Institucional de Enfermedades Neuromusculares. El estado nutricional se evaluó mediante el índice de masa corporal (IMC), el peso esperado para masa muscular cero (ZMM%) y el índice de creatinina-talla (CHI%). Los índices respiratorios evaluados fueron espirometría, presiones inspiratorias y espiratorias estáticas máximas en la boca (MIP y MEP) y flujo espiratorio pico tosido (PCF). Se incluyeron un total de 36 pacientes con ELA y 34 con DMD. Ambos grupos mostraron una disminución de la masa muscular corporal y un exceso de grasa corporal (p <0.001). Solo en el grupo ELA hubo una débil correlación positiva entre el IMC y las variables respiratorias. En ambos grupos, el índice ZMM% no se correlacionó con ninguna variable respiratoria. El CHI% mostró la relación lineal positiva más fuerte (r > 0.700) con FVC%, MIP%, MEP% y PCF% tanto en pacientes con ELA como con DMD (p < 0.001). El IMC no reflejó con precisión la composición corporal y subestimó el exceso de grasa. Este estudio pone en perspectiva la relevancia de la evaluación compartimental para evaluar la función de la musculatura respiratoria y establece que la masa muscular corporal es el parámetro nutricional más relevante en relación a la fuerza de la musculatura respiratoria.
