Dr. Sara McCoy, a dedicated rheumatologist and Sjögren's specialist, delves into the complexities of Sjögren’s Disease, which intricately impacts multiple organs beyond dry eyes and mouth. She discusses how patients' antibody profiles can reveal disease severity, and the potential of advanced diagnostics like salivary gland ultrasounds. Excitingly, she highlights pioneering uses of mesenchymal stromal cells that may transform treatment options. The importance of structured diagnosis and support networks for patients is also emphasized, shedding light on the future of Sjögren's research.
Sjögren's disease is now recognized for its systemic effects, impacting multiple organs like the lungs and kidneys, highlighting its complexity beyond common symptoms.
Research into innovative therapies, including stromal cells and personalized treatment approaches, aims to improve symptom management and patient quality of life.

Understanding Sjogren's Disease
Sjogren's disease is recognized as a complex autoimmune condition that goes beyond common symptoms like dry eyes and mouth. The name change from 'Sjogren's syndrome' to 'Sjogren's disease' reflects a growing understanding of its systemic nature, which can affect multiple organs, including the lungs and kidneys. This shift aims to emphasize the disease's intricacies rather than define it by a set of vague symptoms. Addressing Sjogren's requires comprehensive diagnostic techniques, including a labial salivary gland biopsy and antibody testing to assess severity and tailor treatments.
Diagnostic Challenges and Techniques
Diagnosing Sjogren's involves addressing the pervasive symptoms of dryness and determining whether they stem from the disease or other causes. Utilizing clinically validated questionnaires and tests such as the Schirmer's test and unstimulated salivary flow can help differentiate Sjogren's from other conditions. The conversation also touches on the challenges of identifying seronegative patients, who often lack detectable antibodies like SSA, yet may still suffer from the disease. Therefore, labial salivary gland biopsies are essential for those without positive antibody tests to confirm a diagnosis.
Innovative Treatment Approaches
Current treatments for Sjogren's primarily focus on relieving symptoms through supportive measures, but there's promising research into new therapeutic options. Traditional medications like hydroxychloroquine may not work for everyone, and the need for individualized treatment pathways is growing. Researchers are exploring the potential role of stromal cells in therapy, which may offer a novel way to address the autoimmune aspects of the disease. Ongoing clinical trials aim to assess the effectiveness of these innovative therapies in improving symptoms and overall quality of life for patients.
Monitoring and Future Directions
Effective monitoring of Sjogren's disease is crucial due to its heterogeneous nature and potential progression over time. Regular assessments can help identify complications, including the risk of lymphoma and other autoimmune conditions. A thorough understanding of patient symptoms and appropriate laboratory tests, such as CBC with DIF and salivary gland ultrasounds, is fundamental for tailored management. With the potential for new drugs becoming available, a focus on endotyping patients based on their unique symptoms and disease activity could lead to substantial improvements in treatment outcomes.
Dr. Sara McCoy, rheumatologist and Sjögren’s specialist, a “Sjögrensologist”, joins us this week for an in-depth look at Sjögren’s Disease. We address how the systemic nature of this disease can affect everything from the lungs to the kidneys, why traditional treatments may not always work, why a patient’s antibody profile may hold the key to their disease severity, the use of new biomarkers, the role of advanced diagnostics and ground-breaking developments in the use of stromal cells in treatment and so much more!
