Transdisciplinarity in the approach to amyloidosis.

The increasing complexity in the approach to diseases challenges the development of a new paradigm of care that crosses disciplinary limits, where professionals from different disciplines approach a problem applying their expertise, respecting the knowledge of the other and contributing to the global view of the problem. Amyloidoses are rare diseases. The diagnosis is based on the biopsy of those organs in which amyloid infiltration is suspected. There is an increased risk of bleeding associated with these procedures. Therefore, the availability of obtaining samples from certain sites with less invasive accesses, such as the minor salivary glands (GSM), represent an alternative. Objectives: Describe the experiences of GSM biopsies as a diagnostic tool in the detection of amyloidosis and its intra and postoperative complications. - Estimate the diagnostic performance. The design is a cross-sectional cohort. All patients with a suspected diagnosis of amyloidosis were consecutively included, between August 2018-September 2020. Results: 23 biopsies were performed with minimally invasive procedures. 60.86% were male and the average age was 66 years. The prevalence of amyloidosis was 33%. The sensitivity was 55% and the specificity 100%. One patient had more bleeding than usual during the procedure and none had postoperative complications. Conclusions: GSM biopsy experiences were described as a diagnostic tool for amyloidosis, reporting a slight intraoperative complication and no postoperative complication. The test achieved a sensitivity of 55% and a specificity of 100%.
