Repeat Exposure to Mesh-Glue Dressing Is Associated With Allergic Contact Dermatitis: A Prospective Cohort Study

Area of Science:

• Orthopedic Surgery
• Dermatology
• Allergic Contact Dermatitis Research

Background:

• Allergic contact dermatitis (ACD) is a known complication associated with certain postoperative dressings.
• ACD presents as a localized eczematous reaction around surgical incisions.
• The specific self-adhesive polyester mesh and 2-octyl cyanoacrylate liquid adhesive dressing is under scrutiny.

Purpose of the Study:

• To compare the incidence of ACD in patients undergoing arthroplasty with prior exposure versus those naive to a specific mesh-glue dressing.
• To identify if previous exposure to the self-adhesive polyester mesh and 2-octyl cyanoacrylate liquid adhesive increases ACD risk.

Main Methods:

• Prospective evaluation of 222 patients (245 procedures) undergoing arthroplasty.
• Patients categorized as 'exposed' or 'naïve' to the specific mesh-glue dressing.
• ACD incidence assessed on postoperative days 7 and 14; multivariable logistic regression used for analysis.

Main Results:

• ACD occurred more frequently in previously exposed patients (8.1%) compared to naïve patients (1.9%).
• Previous exposure to the dressing was an independent risk factor for ACD (OR: 6.48, P = 0.003).
• No significant differences in baseline demographics or comorbidities between exposed and naïve groups.

Conclusions:

• Prior exposure to the mesh-glue dressing increases the risk of developing ACD by approximately 6-fold.
• This reaction is likely a type-IV delayed hypersensitivity.
• Clinicians should carefully consider the risk of ACD recurrence with repeat use of this dressing.
