The Critical Role of Multidisciplinary Teams in the Management of Rare Systemic Rheumatic Diseases with Renal Involvement

Abstract Rare systemic rheumatic diseases (RISD) with renal involvement, such as anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis and systemic lupus erythematosus, require complex, coordinated care. These conditions often involve renal complications requiring specialized and timely intervention. Traditional care models, typically fragmented across specialties, are insufficient to meet the nuanced needs of these patients. This article highlights the essential role of structured multidisciplinary teams (MDT)-including nephrologists, rheumatologists, pulmonologists, internal medicine specialists, and other specialists-in improving diagnosis, treatment, and outcomes. Evidence shows that MDT reduces hospitalizations, infections, and mortality while enhancing patient satisfaction and access to innovative therapies. In Portugal, broader implementation of MDT clinics is needed to ensure timely, integrated care. MDT should become the standard for managing these rare, high-risk conditions.
