Cost benefit of patch testing with textile finish resins

Area of Science:

• Dermatology
• Allergology
• Occupational Health

Background:

• Textile dermatitis is a common concern for patients with suspected skin allergies.
• Identifying specific allergens in textile finishes is crucial for effective diagnosis and management.

Purpose of the Study:

• To evaluate the diagnostic utility of textile finish resin patch testing in patients with suspected textile dermatitis.
• To determine the prevalence of allergic textile dermatitis and identify common causative agents.

Main Methods:

• Retrospective analysis of 11 years of patch testing data from 428 patients.
• Patch testing with a limited series of textile finishes, including formaldehyde.
• Correlation of patch test results with clinical diagnosis of allergic textile dermatitis.

Main Results:

• Fifteen cases of allergic textile dermatitis were identified among 428 patients.
• Ten patients had positive patch tests to textile finishes; all 15 were formaldehyde sensitive.
• No novel or unexpected positive reactions to textile finishes were observed.

Conclusions:

• Formaldehyde sensitivity is a key factor in allergic textile dermatitis.
• A negative formaldehyde patch test can effectively rule out allergic contact dermatitis from textile finishes.
• The study validates the use of a limited textile finish series for patch testing.
