A major new study has identified two distinct disease patterns in young people diagnosed with Sjögren disease during childhood. The findings suggest doctors must adopt more personalized treatment strategies. Researchers from University College London tracked 30 young people, mostly female, who received their Sjögren diagnosis in childhood. The participants were followed into young adulthood. This longitudinal analysis provides crucial insights into how the autoimmune condition progresses over time.
Childhood-onset Sjögren disease (CSjD) showed two clear paths. Patients exhibited either consistently high or low disease activity. They also demonstrated either a high or low symptom burden. Crucially, these two factors did not always align. A patient with low disease activity could still suffer from a high number of reported symptoms. Conversely, some with high disease activity might report lower symptom severity. This decoupling highlights the disease’s complex nature. It also stresses the need to consider patient-reported distress alongside clinical scores.
The study utilized established scoring systems for assessment. Researchers tracked disease activity, symptom severity, and accumulated damage. This comprehensive approach allowed them to map the disease’s course precisely. The mean age of onset was approximately 12.7 years for the cohort. Participants were followed for an average of 10 years after diagnosis.
At the initial diagnosis, patients most commonly suffered from fatigue and joint pain (arthralgia). Half of the group experienced swelling in the parotid and submandibular glands. Dryness of the eyes and mouth was also a frequent complaint. Researchers noted a significant diagnostic delay for some patients. Those whose diagnosis took more than three years from symptom onset reported a much higher prevalence of dryness. This delay suggests that earlier diagnosis could potentially mitigate the severity of certain persistent symptoms.
The long-term outcomes also revealed significant concerns. More than half of the participants had accumulated measurable organ damage by the final assessment. Worse, a notable portion of the group developed lymphoma. This finding underscores the serious, systemic risks associated with the condition. It also highlights the urgent need for better diagnostic tools and effective early interventions.

The researchers strongly emphasized the disease’s high heterogeneity. Their work clearly demonstrates that Sjögren disease in children is not a single, uniform condition. The authors suggest that one-size-fits-all treatment plans are insufficient. Doctors should instead utilize tailored management approaches. These strategies must address both the clinical control of the disease and the substantial impact of symptoms on the patient’s quality of life. The study offers rheumatologists and other specialists a clearer framework for predicting long-term risks and improving care for this vulnerable patient group.
