Comparison Between Behçet's Uveitis Patients with Immunologically Positive and Immunologically Negative Tuberculosis...

Area of Science:

• Ophthalmology
• Immunology
• Infectious Diseases

Background:

• Behçet's disease is a multisystem inflammatory disorder.
• Ocular involvement, particularly uveitis, is a common and potentially vision-threatening manifestation of Behçet's disease.
• The role of latent tuberculosis infection (LTBI) in modulating the clinical presentation of Behçet's uveitis requires further elucidation.

Purpose of the Study:

• To investigate the clinical characteristics of Behçet's uveitis patients with and without latent tuberculosis infection (LTBI).
• To compare the incidence of specific ocular and systemic manifestations between these two groups.

Main Methods:

• A retrospective comparative study was conducted on 40 Behçet's disease patients attending a Uveitis subspecialty clinic.
• Patients were divided into two groups: 20 with positive tuberculosis immunology (Group 1) and 20 with negative tuberculosis immunology (Group 2).
• Clinical features, treatment responses, and laboratory findings were analyzed.

Main Results:

• Macular edema was more frequent in patients with negative TB immunology (Group 2) (p=0.013), who also received more systemic corticosteroids (p=0.011).
• Vascular occlusion was more prevalent in patients with positive TB immunology (Group 1) (p=0.044).
• Significant differences in laboratory findings, including anemia, elevated ESR, C-reactive protein, and HbA1c, were noted between the groups (p<0.001).

Conclusions:

• Behçet's uveitis patients with negative TB immunology are at higher risk for macular edema.
• Patients with positive TB immunology show an increased likelihood of vascular occlusion and elevated inflammatory markers (ESR, CRP).
• These findings suggest LTBI influences the clinical phenotype of Behçet's uveitis, impacting treatment strategies and patient outcomes.
