Familial Mediterranean fever associated with optic neuritis, successfully treated with anti-interleukin 1 agents.

Familial Mediterranean fever (FMF) is an inherited periodic auto-inflammatory disease characterized by recurrent attacks of fever, synovitis and serositis. Ophthalmological manifestations of FMF are extremely rare. Here we described a boy who has been followed-up for FMF and attended with a loss of vision during the course of the disease. He was diagnosed with optic neuritis. As the other etiologies were excluded his optic neuritis was attributed to the underlying auto inflammatory process. After pulse steroid therapy, his symptoms improved and a complete remission occurred. Afterwards he had two more optic neuritis attacks. Thereafter anti-interleukin 1 (IL-1) drugs were introduced and he did not develop further attacks of both optic neuritis and FMF. This case presentation highlights the possible association between FMF and optic nerve involvement.

Clinical characteristics of paediatric neuro-Behçet's disease: a single tertiary centre experience.

OBJECTIVES: To investigate the demographic and neurological features and treatment modalities of neuro-Behçet's disease (NBD) in children, to share our experiences and to summarise the literature. METHODS: We retrospectively reviewed the medical records of Behçet's disease (BD) patients who attended our paediatric rheumatology department between December 2005 and October 2013. Five patients had the diagnosis of NBD. Initial neurological presentation, clinical BD presentation, magnetic resonance imaging pictures of those five patients was recorded. RESULTS: A total of 18 patients were diagnosed with BD. Among BD patients five of them were identified with NBD (27.8%). The mean age of NBD patients at the time of diagnosis was 12.4 years (range 5.5-15 years). The mean follow-up time after the neurological involvement was 5.2 years (range 0.5-14). In two cases neurological involvement occurred at the same time with the onset of other clinical findings of BD (40%). Both of these patients had parenchymal involvement. Three patients were admitted with headache as the initial neurological symptom. They revealed benign intracranial hypertension. One of them had cerebral venous sinus thrombosis (CVST). The other two had normal cranial magnetic resonance imagines. All patients received colchicine and steroid, two of them who had parenchymal involvement received also cytotoxic drugs. CONCLUSIONS: This study has shown that neurological symptoms can be the first manifestations of BD in children. Clinicians should be aware of this possibility and when a patient presents with neurological manifestations, it would be valuable to query the patient for the clinical features of Behçet's disease.
