Nutritional profile of lung transplant candidates.

OBJECTIVE

To determine the nutritional profile of lung transplant candidates.

METHODS

A retrospective cross-sectional study involving lung transplant candidates at a public hospital in the city of São Paulo, Brazil. Data related to gender, age and underlying lung disease were compiled for the participants. For the assessment of the nutritional profile of the patients, body mass index (BMI), mid-arm muscle circumference (MAMC), waist circumference and triceps skinfold thickness (TST) were determined during the first outpatient visit.

RESULTS

We included 117 patients, 69 of which (59%) were male. The mean age of the participants was 42.5 +/- 15.2 years. The most prevalent underlying disease, seen in 29 patients (24.8%), was pulmonary emphysema. The nutritional profile was considered normal in 48.3% of the patients with pulmonary emphysema, 55% of those with cystic fibrosis, 56% of those with bronchiectasis and 50% of those with other lung diseases. The majority (51.7%) of the patients with pulmonary fibrosis were classified as overweight. The TSTs indicated that the risk of depletion was highest (64.7%) among the patients with cystic fibrosis, followed by those with bronchiectasis (52.6%).

CONCLUSIONS

Patients with pulmonary fibrosis presented the highest BMIs, although the corresponding TSTs and MAMCs were normal. Patients with cystic fibrosis and bronchiectasis presented the highest prevalence of nutritional depletion, based on TST and MAMC.
