BACKGROUND AND PURPOSE: To evaluate changes in cortical excitability induced by zonisamide (ZNS) in focal epilepsy patients. METHODS: Twenty-four drug-nasmall yi, Ukrainianve focal epilepsy patients (15 males; overall mean age 29.8 years) were enrolled. The transcranial magnetic stimulation parameters obtained using two Magstim 200 stimulators were the resting motor threshold, amplitude of the motor-evoked potential (MEP), cortical silent period, short intracortical inhibition, and intracortical facilitation. These five transcranial magnetic stimulation parameters were measured before and after ZNS, and the findings were compared. RESULTS: All 24 patients were treated with ZNS monotherapy (200-300 mg/day) for 8-12 weeks. After ZNS, MEP amplitudes decreased (-36.9%) significantly in epileptic hemispheres (paired t-test with Bonferroni's correction for multiple comparisons, p<0.05), whereas the mean resting motor threshold, cortical silent period, short intracortical inhibition, and intracortical facilitation were unchanged (p>0.05). ZNS did not affect cortical excitability in nonepileptic hemispheres. CONCLUSIONS: These findings suggest that ZNS decreases cortical excitability only in the epileptic hemispheres of focal epilepsy patients. MEP amplitudes may be useful for evaluating ZNS-induced changes in cortical excitability.

5.Valproate-induced Hyperammonemic Encephalopathy: A Case Report.
Brain & Neurorehabilitation 2013;6(2):86-89
Valproate is widely used because of broad spectrum of action, but it can produce an encephalopathy resulting from hyperammonemia even at the therapeutic range of valproate and is called as valproate-induced encephalopathy (VHE). Delay in recognition of VHE can result in the development of potentially life-threatening complications. Fortunately, it is reversible with discontinuing valproate. A 65-year-old man became progressively lethargic with impaired gait and poor cognitive function while taking valproate as alternative to zonisamide. Routine investigations of admission profiles were performed but revealed no abnormalities. Next, we checked serum ammonia level to identify other possible causes and detected hyperammonemia despite the therapeutic range of valproate in the absence of any abnormalities in liver enzymes. On cessation of valproate, he has achieved dramatic clinical improvement including the reversal of hyperammonemia. We confirmed the diagnosis of VHE. This emphasizes the importance of rapid diagnosis and proper management of VHE in order to prevent the neurological damage and minimize complications.

Zonisamide (ZNS) has been proven as a safe, effective, and well-tolerated antiepileptic drug. We report an epilepsy patient who had a severe, dose-dependent, memory deficit after ZNS administration. A 65-year-old man visited our epilepsy clinic due to the occurrence of nocturnal convulsions. Despite the absence of seizures, he developed a severe impairment of verbal and visual memory functions after the increment of ZNS dosage from 200 mg/day to 300 mg/day. We substituted 1,000 mg/day valproic acid for ZNS. His cognitive performances were returned to original levels.

The objective of the study is to monitor on a wide population base the safety and efficacy of zonisamide in patients with partial, generalized, and combined seizures. This is an open label, descriptive, post-marketing surveillance preliminary report that includes the data obtained from October 2008 to May 2010 of a four-year study. The study included 516 patients allocated to either zonisamide monotherapy or zonisamide add-on therapy, with efficacy and safety assessed monthly for three months. For adult patients, a maximum oral dose of 600 mg per day was allowed while a maximum dose of 12 mg/kg/day of zonisamide was allowed for pediatric patients. Efficacy measures were the proportion of responders and percentage change in seizure frequency from baseline. 321 of the 516 patients were included in the efficacy analysis. The responder rates were 53.27%, 80.37%, and 92.52% after the 1st month, 2nd month, and 3rd month of treatment respectively. The use of zonisamide led to seizure-reduction rates of 45.74%, 68.43%, & 82.85% during the 1st, 2nd, & 3rd month of use respectively. Safety analysis was done on all the 516 subjects. Adverse events were mostly mild and observed in 6.78% of patients. No serious adverse events were encountered. 7 subjects (1.4%) discontinued taking zonisamide because of increased seizure frequency in 4 patients, and 1 patient each due to absence of effect on seizure-control, rashes, and thrombocytopenia. All the rest continued taking zonisamide.

OBJECTIVES: We investigated the tolerability, safety, and treatment response to flexible-dose paliperidone ER in patients with non-acute schizophrenia in whom previous antipsychotic drugs were ineffective. METHODS: This 24-week interim analysis of the 48-week multicenter, prospective, open-label study assessed effectiveness using the Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression-Schizophrenia-Severity (CGI-SCH-S) Scale, Personal and Social Performance (PSP) and Drug Attitude Inventory (DAI). Safety and tolerability were assessed using the Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS) and Liverpool University Neuroleptic Side Effect Rating Scale (LUNSERS). RESULTS: Effectiveness was assessed in 169 patients. Significant improvement in the PANSS total score was observed by week-1 and continued until week-24. The response rate was 33%. The CGI-SCH-S and PSP total scores significantly improved during 24 weeks ; however, no change occurred in the total DAI. Fifty-nine percent of patients reported adverse events, of which extrapyramidal symptoms were the most frequent (19.0%). The DIEPSS and LUNSERS scores were improved after 24 week. CONCLUSIONS: Switching to the flexible-dose paliperidone ER from an ineffective antipsychotic drug was safe, tolerable, and showed a good treatment response in Korean patients with schizophrenia.

OBJECTIVE: The aim of this study was to examine how many Korean rheumatoid arthritis (RA) patients fulfilling the 2008 American College of Rheumatology (ACR) recommendation, 2007 British Society for Rheumatology (BSR) guideline and 2010 Japan College of Rheumatology (JCR) guideline for TNF-alpha blocker, meet the Korean National Health Insurance reimbursement criteria and to evaluate the reasons for failing the Korean National Health Insurance reimbursement criteria. METHODS: Data were obtained from a registry of RA patients who visited rheumatology clinics of Hallym university affiliated hospitals. Patients who were previously prescribed with methotrexate or leflunomide for more than 3 months and had at least one DAS28 examination were included in the present study. RESULTS: Of 642 patients included, 118 episodes meeting ACR guideline for using TNF-alpha blocker were identified in 88 patients (13.7%). In addition, 19 episodes meeting BSR guideline in 17 patients (2.6%) and 21 episodes meeting JCR guideline in 21 patients (6.2%) were identified. Four episodes (4.8%) meeting ACR recommendation, 0 episodes meeting BSR criteria and 5 episodes (12%) meeting JCR criteria, respectively, were eligible for TNF-alpha blocker according to the Korean National Health Insurance reimbursement guideline. The most common reason for failing the Korean National Health Insurance reimbursement criteria was the number of active joint counts (92.6%). CONCLUSION: Our results show that the majority of RA patients satisfying the ACR guideline, BSR and JCR guideline for use of the TNF-alpha blocker did not meet the Korean National Health Insurance reimbursement criteria. Patients most often failed due to active joint count criteria.

OBJECTIVE: The aim of this study was to demonstrate changes of subjective medication satisfaction and clinical benefit after once-daily paliperidone extended release (ER) in treatment of schizophrenia. METHODS: In an open-label, observational, and multicenter study, 374 patients with schizophrenia who switched to paliperidone ER due to any reason were recruited. Medication Satisfaction Questionnaire (MSQ), Clinical Global Impression-Severity (CGI-S), Clinical Global Impression-Improvement and visual analogue scale for sleep (VAS) were assessed at baseline, 4 weeks and 8 weeks after treatment. We also examined the type, frequency, and severity of adverse events newly formed. RESULTS: Among 374 patients, 320 patients (76.5%) were included in the intent-to-treat analysis set. The mean dose of paliperidone ER was 5.33+/-2.31 mg/day at the initiation. At the endpoint, the mean dose of paliperidone ER was 6.68+/-3.13 mg/day. The percentages of patients satisfied with medication were changed from 40.9% at baseline to 67.8% at endpoint (p<0.001). Both CGI-S scores and VAS for daytime drowsiness were significantly decreased after 8 weeks (both p<0.0001) and mean scores of MSQ and VAS for sleep quality were improved after 8 weeks (both p<0.0001). CONCLUSION: After switching to paliperidone ER, 67.8% of patients with schizophrenia who had any reason to switch medication showed subjective satisfaction for medication and clinical improvement without significant adverse events. Regarding that medication satisfaction was associated with changes of clinical states, medication satisfaction can be used for measures for clinical scales in the treatment of schizophrenia.
