RESUMO

OBJETIVO:

Relatar quatro casos de bronquiolite decorrente de exposição a aroma artificial de manteiga em uma fábrica de biscoitos no Brasil.

MÉTODOS:

Descrevemos os achados clínicos, espirométricos e tomográficos nos quatro pacientes, assim como achados de biópsia pulmonar em um dos pacientes.

RESULTADOS:

Os quatro pacientes eram homens jovens, não fumantes, e desenvolveram obstrução persistente ao fluxo aéreo (relação VEF1/CVF reduzida e VEF1 de 25-44% do previsto) após 1-3 anos de exposição a diacetil, sem a utilização de equipamentos de proteção individual, em uma fábrica de biscoitos. A TCAR mostrou achados indicativos de bronquiolite. Em um paciente, a biópsia pulmonar cirúrgica mostrou bronquiolite obliterante associada a células gigantes.

CONCLUSÕES:

A bronquiolite decorrente de exposição a flavorizantes artificiais deve ser considerada em trabalhadores com obstrução ao fluxo aéreo no Brasil.
ABSTRACT

OBJECTIVE:

To report the cases of four patients with bronchiolitis caused by exposure to artificial butter flavoring at a cookie factory in Brazil.

METHODS:

We described the clinical, tomographic, and spirometric findings in the four patients, as well as the lung biopsy findings in one of the patients.

RESULTS:

All four patients were young male nonsmokers and developed persistent airflow obstruction (reduced FEV1/FVC ratio and FEV1 at 25-44% of predicted) after 1-3 years of exposure to diacetyl, without the use of personal protective equipment, at a cookie factory. The HRCT findings were indicative of bronchiolitis. In one patient, the surgical lung biopsy revealed bronchiolitis obliterans accompanied by giant cells.

CONCLUSIONS:

Bronchiolitis resulting from exposure to artificial flavoring agents should be included in the differential diagnosis of airflow obstruction in workers in Brazil.
