Bronchial asthma due to sensitization to chloramine T
Summary
Occupational asthma can be caused by Chloramine T, a food industry disinfectant. This case study highlights a dairy worker
Area of Science:
- Occupational health
- Immunology
- Allergology
Background:
- Chloramine T is a potent bactericidal disinfectant used in the food industry.
- It was first identified as an occupational sensitizer in 1945.
- It can induce IgE-mediated asthma, fever, and leukocytosis.
Observation:
- A male dairy worker developed rhinitis and asthma after four years of exposure.
- Skin tests for Chloramine T were positive at 10 mg/ml.
- Other tested allergens yielded negative results.
Findings:
- Specific IgE antibodies for Chloramine T were detected (12 PRU).
- Bronchial provocation tests confirmed immediate and late bronchoconstriction.
- The patient's symptoms were consistent with Chloramine T sensitization.
Implications:
- This case underscores the risk of Chloramine T as an occupational sensitizer.
- Highlights the importance of recognizing and diagnosing Chloramine T-induced occupational asthma.
- Suggests the need for preventative measures in food industry settings with Chloramine T exposure.
