Paediatric Behçet's disease with sinus venous thrombosis: experience from three centres in Turkey.

OBJECTIVES

To report our experiences of the juvenile Behçet's disease (BD) patients with cerebral venous sinus thrombosis (CVST) and to review previous studies reporting the clinical characteristics and outcomes of juvenile BD with CVST.

METHODS

Clinical characteristics and outcomes of paediatric patients with CVST who met the Paediatric Behçet's Disease (PEDBD) classification criteria for juvenile BD from 3 referral centres in Turkey were reviewed retrospectively. A systematic review of literature of all published data was conducted.

RESULTS

The study group consisted of 12 juvenile BD patients with CVST. At the time of CVST diagnosis, the most common symptom was headache (100%), followed by vomiting (25%), blurred vision (16.7%), and disturbances in eye movements (16.7%). Six (50%) patients presented with CVST. Transverse sinus was the most frequently affected sinus (9/12, 75%) followed by superior sagittal sinus. The mean (±2SD) BDCAF at the CVST diagnosis was 6 (±3.8). Four children (33.3%) had another venous thrombosis apart from CVST. All patients received pulse methylprednisolone for three consecutive days continued with oral prednisolone. Steroid treatment was tapered and discontinued minimum in six months. Eleven patients received azathioprine concomitant to steroid treatment at the time of CVST. All the patients received anticoagulant therapy concomitantly. Only one patient who did not receive azathioprine relapsed. Median follow-up period was 4 years (IQR: 2-5.4). In the literature review, we identified nine articles, describing 35 pediatric CVST patients associated with BD. Thirty patients achieved remission, while five patients had residual neurologic deficit.

CONCLUSIONS

Neuroimaging is very important in the diagnosis of NBD. We suggest that treatment with immunosuppressants and steroid treatment is essential to decrease the adverse events of corticosteroids in the pediatric population and decrease relapses. Further multicenter studies with prospective follow-up may guide us in better management of these patients.
