Nutritional Assessment in Non-tuberculous Mycobacteria Pulmonary Disease

Overview

Non-tuberculous mycobacterial (NTM) pulmonary disease (PD) is an emerging condition with heterogeneous manifestations from both the microbiological and the clinical point of view. Diagnostic and therapeutic guidelines are available but there are still unmet patients' and physicians' needs, including the exams to perform in the nutritional evaluation and intervention to improve health-related QoL and to control gastrointestinal side-effects during antimicrobial therapy, particularly in those with low body mass index and history of weight loss.

The aim of the study is to evaluate the nutritional status in patients with non-tuberculous mycobacterial pulmonary disease (NTM-PD) and to provide an initial assessment of the potential impact of the introduction of targeted antibiotic therapy on the nutritional status itself. Specifically, the primary objective is the assessment of the proportion of underweight subjects, i.e. with Body Mass Index (BMI) \<18.5 kg/m2, to confirm that it is significantly higher than that of the general Italian population. Study Design: Multicenter Cohort Pilot Observational Study Participation in the study consists of two pneumological visits, as per normal clinical practice, (at the beginning of the study, T1, after 6 months, T3, and at the end of the antimicobacterial antibiotic therapy, T5) in which the collection of past medical history, measurement of oxygen saturation, pulmonary functional tests and 6-minute walking tests will be performed. In addition, nutritional assessments (T2, T4, T6) will be carried out at the same time as the pulmonary visits. Nutritional assessments will include anthropometric measurements, questionnaires on nutritional status and physical activity, performing blood chemistry tests, bioimpedance, dynamometry and gait speed 4 meters, to evaluate body composition and physical performance.
