In the present pilot study, a possible relation between the implantation of PP mesh for inguinal hernia, vaginal prolapse and SUI repair and subsequent systemic auto-immune complaints is investigated by testing immunologic and allergic responses in fifty patients with suspected ASIA syndrome. Additional value of MAT is investigated and effectiveness of (partial) PP mesh removal for these complaints is assessed. If so, a profound insight in diagnostics and treatment for systematic complaints will be attained that may provide opportunities for future diagnostics.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Positive diagnostic tests | Rate of positive diagnostic tests of either blood draws or MAT as an indication for presence of an autoimmune disease. | At inclusion. There is no need to repeat this test after first result. | |
Secondary | Autoimmune complaints and objective findings in immunologic blood test | Association between subjective outcomes of autoimmune/inflammatory symptoms and objective findings in blood tests that indicate presence of inflammation or autoimmunity. | At inclusion, questionnaires repeated after 6 and 12 months. Blood tests will not be repeated after tests at inclusion. | |
Secondary | Autoimmune complaints and objective findings in mesh allergy test (MAT) | Association between subjective outcomes of autoimmune/inflammatory symptoms and objective findings of the mesh allergy test (MAT) that either indicate presence of intolerance to mesh, or indicate no dermal/allergic reaction to the material of the mesh. | At inclusion, questionnaires repeated after 6 and 12 months. MAT will not be repeated after test at inclusion due to either a positive test (and therefore emergence of immune memory cells) or negative test (and therefore no immune response to mesh at t0) | |
Secondary | Mesh removal and subjective complaints | Success rate of mesh removal for the resolution of subjective complaints using Tissue Connective Disease Screening Questionnaire (CSQ) and Patient Global Impression of Improvement (PGI-I) questionnaire and ASIA symptoms. | Follow-up 1 year after surgery. At inclusion, questionnaires repeated after 6 and 12 months. | |
Secondary | Mesh histopathology | All explanted meshes will be examined histopathologically to check for granulomatous inflammatory or acute inflammatory reactions surrounding the explant. | Directly after surgery if surgical mesh removal is deemed safe by the surgeon and preferred by the patient. As attempts will be made to completely remove the mesh, mesh histopathology will only be performed once. | |
Secondary | Patient demographics | Baseline patient demographics will be collected for all included patients, as well as for patients undergoing surgical mesh removal. Descriptive analysis will be performed. | At the start of the inclusion period demographics will be recorded. Demographics will also be recorded for the population undergoing surgery, in combination with Outcome measure 3 of subjective complaints. |
