Contactin associated protein-like 2 (CASPR2) and leucine-rich glioma-inactivated protein 1 (LGI1) voltage gated potassium channel (VGKC) proteins are found in both the central and peripheral nervous systems [1]. Antibodies against these proteins are associated with encephalopathy, seizures, peripheral nerve hyper-excitability, autonomic dysfunction, hyponatremia, pain, and insomnia in varying severity and combination [1].

Morvan syndrome, first described in 1890, combines symptoms of peripheral nervous system (PNS), central nervous system (CNS), and autonomic nervous system dysfunction. It was later found to be associated with VGKC-complex antibodies, mainly against CASPR2 or LGI1 or both.

Our patient had a history of anti-LGI1 positive limbic encephalitis, which presented years later with anti-CASPR2 positive Morvan syndrome.

Behçet's disease (BD) is a multi-systemic disorder of unknown etiology characterized by relapsing oral-genital ulcers, uveitis, and involvement of the articular, gastrointestinal, neurologic, and vascular systems. The choice of treatment is based on the severity of systemic involvement, clinical presentation and the site affected, and includes corticosteroids, azathioprine, interferon, cyclophosphamide, methotrexate or tumor necrosis factor-alpha and interleukin-1 blockers. We present a case series of four refractory BD patients successfully treated with intravenous immunoglobulins (IVIG). All patients fulfilled International Study Group criteria. The patients’ mean age was 38.75 ± 12.09 years and mean disease duration 10.25 ± 8.5 years. Human leukocyte antigen B51 was positive in two of four patients. In addition to oral aphthosis, all patients suffered from genital ulcers and cutaneous BD-related manifestations; central nervous system involvement and arthralgia were found in two patients. Peripheral nervous system, gastrointestinal and eye involvement occurred in 25% of cases. In all patients, previously treated according to EULAR recommendations without reaching satisfactory results, IVIG induced immediate and sustained response over time without incurring any side effects. We propose IVIG administration as an additional effective and safe treatment option in patients with severe and resistant BD.
