Clinical and Demographic Features of Pediatric-Onset Behçet's Disease and Evaluation of Optical Coherence Tomography Findings.

PURPOSE: To evaluate the clinical characteristics, including spectral domain optical coherence tomography (SD-OCT) findings, of pediatric-onset Behçet's disease (PBD) patients. METHODS: Medical records of 23 PBD (15 males and 8 females) and 24 (15 males and 9 females) healthy subjects were evaluated retrospectively. The main outcomes were compared between PBD patients, with and without ocular involvement, and healthy subjects. RESULTS: The mean age at onset was 12.00 ± 2.10 years. Mean follow-up period was 25.17 ± 15.36 months (range 6-48). Retinal vasculitis was the most common ocular finding (7 patients). Most of the complications of systemic treatment were associated with long term corticosteroid therapy. There was no significant difference between the mean retinal thickness of the PBD patients and healthy controls (p > 0.05). The mean choroidal thickness was significantly increased in all measured segments of PBD patients with ocular involvement (p < 0.01). CONCLUSION: Choroidal thickness of PBD patients with ocular involvement was significantly thicker compared to the PBD patients without ocular involvement and to healthy control subjects.

Serum Cortistatin Levels in Patients with Ocular Active and Ocular Inactive Behçet Disease.

PURPOSE: To evaluate serum cortistatin (CST) levels in patients with ocular active and ocular inactive Behçet disease (BD) and its relationship with disease activity. METHODS: 24 BD patients with ocular active, 24 BD patients with ocular inactive patients and 24 healthy control subjects were included in the study. RESULTS: In ocular active and ocular inactive BD patients and healthy control subjects, the mean serum CST levels were 4.38 ± 1.63ng/ml, 5.46 ± 1.81ng/ml and 7.56 ± 1.73ng/ml, respectively. ESR, serum CRP, CST levels and NLR were significantly different between the groups (p < 0.001 for all). The CST levels were similar between ocular active and inactive BD patient groups (p = 0.197). ESR, CRP and NLR were significantly higher in ocular active BD patients compared to ocular inactive BD patients and healthy control subjects (p < 0.05 for all). CONCLUSION: Serum CST level was significantly lower in BD patients. CST may be a neuropeptide that plays a role in the pathogenesis of BD.
