Autoimmunity and hernia mesh: fact or fiction?

Area of Science:

• Medical research
• Immunology
• Surgical materials science

Background:

• Increasing patient reports suggest autoimmune or allergic reactions to surgical mesh post-hernia repair.
• Hypersensitivity or autoimmunity caused by surgical mesh has not been scientifically proven.
• Distinguishing foreign body reactions from true autoimmunity is crucial.

Conclusions:

• Limited evidence supports polypropylene mesh causing autoimmunity.
• Multiple autoimmunity triggers and genetic predisposition complicate establishing a direct cause-and-effect relationship.
• A chronic foreign body reaction to biomaterials is distinct from autoimmunity.
