The immunosuppressant, cyclosporin A (CsA), is neuroprotective following brain injury. Previous studies suggest that CsA treatment ameliorates seizure severity during status epilepticus (SE) or cell death following SE. The antiepileptic effects of CsA on recurrent seizures, however, have not been investigated. In the present study, the effects of CsA on spontaneous recurrent seizures (SRSs) in a kainate (KA)-induced mouse model of mesial temporal lobe epilepsy (TLE) were examined. Moreover, the effects of CsA on epileptiform activity in a 4-aminopyridine (4-AP)-induced in vitro seizure model were investigated. A mesial TLE mouse model was generated with a unilateral intrahippocampal injection of KA. SRSs were determined in the ipsilateral hippocampal CA1 region with a long-term video-EEG. CsA was systemically administrated to the epileptic mice exhibiting a stable occurrence of SRSs. A 1-mg/kg dose of CsA did not have any effect on SRSs in the epileptic mice. However, a 5-mg/kg dose of CsA significantly reduced the number of SRSs and decreased the severity of the seizures in the epileptic mice. Additionally, CsA treatment inhibited spontaneous burst discharges in 4-AP-treated hippocampal slices. The results of the present study demonstrate that CsA inhibits recurrent seizures in a mouse model of mesial TLE and suggest that CsA may afford both neuroprotection against SE and antiepileptic effects during the chronic period of epilepsy.

A 1-year-old boy was admitted because of febrile status epilepticus (FSE). A secondary cluster of seizures was seen on day 5 after onset, and the patient eventually displayed developmental delay. Conventional magnetic resonance imaging (MRI) showed no abnormal findings on day 1 after onset, but showed reduced diffusion in the subcortical regions of bilateral frontal lobes on day 5 after onset. Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) was diagnosed. Arterial spin labeling (ASL) revealed reduced cerebral blood flow (CBF) in bilateral frontal lobes on day 1 after onset and showed increased CBF in the corresponding region in the subacute phase. Outcomes after prolonged febrile seizures are usually good, but mental deficit and/or epilepsy often remain in AESD. Discriminating between these syndromes is difficult, because no useful biomarkers have been identified. Reduced CBF in bilateral frontal lobes was observed on ASL on day 1 of FSE in the present case, and this finding may be predictive of developing AESD.
