Characterizing autoimmune uveitis to systemic diseases: a retrospective study from a Syrian tertiary reference center.

BACKGROUND

Uveitis, a notable cause of severe visual impairment, is frequently characterized as infectious or noninfectious autoimmune uveitis (AU), the latter of which is commonly associated with younger individuals and systemic diseases. Despite the condition's widespread impact, there are substantial gaps in the comprehension of its pathogenesis, clinical presentation, and therapeutic response, particularly concerning systemic disease-associated uveitis.

AIM OF THE STUDY

The current study aims to bridge these gaps through an extensive examination of demographic and clinical features in AU patients, thereby informing future research, and therapeutic strategies, and improving patient outcomes.

METHODS

This retrospective observational study analyzed 261 patients with systemic disease-associated uveitis from January 2018 to December 2022 in Damascus, Syria. With diagnoses made using the Standardization of Uveitis Nomenclature Working Group Criteria, the study evaluated tailored treatment efficacy at the 24-month post-treatment mark, alongside comprehensive ophthalmic examinations, laboratory evaluations, and radiographic assessments.

RESULTS

In our study, included 87 patients with Systemic Disease-Associated Autoimmune Uveitis (SDA-AU). Women represented 64.36% of this group, and the mean age at diagnosis was 39.8±17.9 years (range 7-71) for men and 43.8±15.4 years (range 11-69). The most reported symptom was a painful red eye (52.87%). The onset of symptoms was sudden for 32.18% of patients, while 67.81% reported gradual development. Complications occurred in 33.33% of patients, including cataracts (41.37% of those with complications) and glaucoma (17.24%). Laboratory evaluations showed elevated inflammation markers in 66.66% of patients. Upon the 24-month assessment, 48.27% of patients achieved complete remission, 37.93% showed significant improvement, while disease worsened in 13.79% of cases.

CONCLUSION

Our findings demonstrated that the presentation of AU in this cohort frequently precedes the diagnosis of systemic diseases, affirming the vital role of an early and accurate diagnosis of uveitis for the detection of underlying systemic conditions. In conclusion, our study underlines the significance of a comprehensive and multidisciplinary approach in the management of SD-AU, leading to improved prognosis and quality of life for patients.
