Persistent and Unusual Respiratory Findings after Prolonged Glutaraldehyde Exposure

Area of Science:

• Occupational Medicine
• Pulmonology
• Toxicology

Background:

• Glutaraldehyde is a widely used disinfectant in healthcare settings, particularly for endoscopic instruments.
• Occupational exposure to glutaraldehyde poses risks for healthcare workers, including irritant-induced and sensitizer-induced asthma.

Observation:

• A healthcare worker with prolonged glutaraldehyde exposure developed chronic respiratory symptoms affecting both upper and lower airways.
• Pulmonary function tests in this patient showed inconsistent results, including restrictive and obstructive patterns with varying responses to bronchodilators.

Findings:

• The case demonstrates that glutaraldehyde-induced occupational asthma can present with diverse clinical and spirometric findings in a single individual.
• Variable inflammation and bronchial hyperresponsiveness contribute to the complexity of diagnosing glutaraldehyde-induced asthma.

Implications:

• Diagnosing occupational asthma, especially from glutaraldehyde exposure, can be challenging due to fluctuating symptoms and pulmonary function test results.
• Repeated pulmonary function testing may be necessary to accurately characterize the airway disease in patients with suspected glutaraldehyde-induced occupational asthma.
