ObjectiveAnalysis prophylactic anti-epileptic drugs (AEDs) therapy in patients with brain tumor-related epilepsy (BTE) to observe whether seizures occurance, frequency will decrease, and the adverse reactions risk assessment of the patient's after using AEDs in 3 months and 12 month. MethodsRetrospective analysis of the cases and follow-up data of patients with the diagnosis of brain tumors in the Second Affiliated Hospital of Chongqing Medical University in June 2011 to February 2015. Through the strict inclusion criteria and exclusion criteria review, the sixty-eight standard patients were divided into two groups:treatment group (44 cases) and control group (24 cases), and compared in the incidence of epilepsy and seizure frequency two groups of patients, and observe the adverse reactions after using AEDs. And analyzed the outcome of patients with brain tumors at 3 months and 2 months. ResultsThrough at least 1 year follow up, compared the data of patients in the two groups with seizure incidence at 3 months and with seizures frequency≥3 times at 12 months, the difference was statistically significant (P < 0.05).In the treatment group, however, 7 patients experienced mild adverse reactions, such as dizziness, fatigue, nausea and vomiting, mild white blood cell reduction, mild liver damage, menstrual cycle changes, mental and behavioral abnormalities, etc.A patient discontinued due to mental disorder, and a patient change AEDs due to menstrual cycle change. All patients had no serious adverse reactions. Conclusions①prophylactic use of AEDs can significantly reduce the incidence of seizures at 3 months; ②Although prophylactic use of AEDs did not reduce the incidence of seizures at 12 months, but can reduce the frequency of seizures; ③The risk of adverse reactions of prophylactic use of AEDs in patients with BTE is relatively low.
ObjectiveTo summarize the occurrence rules of adverse reactions/events of voriconazole, analyze the reasons of adverse reactions/events, and provide reference for clinical medication. MethodsUse China National Knowledge Infrastructure, Vip Journal Integration Platform and Wanfang Data Knowledge Service Platform to search the literatures published in 2015 and before with "voriconazole" "adverse reaction" and "adverse event", classify the adverse reactions/events according to gender, age, system-organs, drug combination, occurrence time, and outcome, and analyze the occurrence regularity and reasons of adverse reactions/events. ResultsA total of 29 literatures were searched, including 44 cases. In all the adverse reactions/events, elderly patients were the most (18 cases with the age of 61-80 years old, occupying 40.9%; 13 cases with >80 years old, occupying 29.5%). Adverse reactions/events mainly involved central nervous system (45 cases, 59.2%). Proton pump inhibitors (5 cases) were the more common drug combination in the 7 drug combination cases. Most adverse reactions/events occurred in 1-7 days after medication (35 cases, 79.5%). The outcome of adverse reactions/events included 39 improvement/recovery, 1 death, and 4 unknown. ConclusionUsing voriconazole should consider the drug characteristics. Choose the drug according to the specific condition of patients, at the same time pay attention to drug interactions, contraindications, and so on. If necessary, genetic testing and therapeutic drug monitoring can be done in order to reduce the occurrence of adverse drug reactions/events.
Objective To investigate the effects of antiepileptic drugs (AEDs) with warfarin functions and blood coagulation system, to provide the reference for clinicians of the selection of AEDs under the combination therapy with warfarin. Methods Analyse the clinical data of the patient with symptomatic epilepsy from the Second Clinical Medical College of Guiyang University of Chinese Medicine on April 1, 2017, whom taking AEDs and warfarin at the same time, clear the drug adverse reactions, and analysed related literature. Results After the treatment with valproate, abnormal blood coagulation, a danger and emergency data appeared, so we stopped using warfarin immediately, and reduce the dosage of valproate gradually, insteadly, we used levetiracetam as antiepileptic therapy. Monitoring blood coagulation function, when it returned to normal, restart warfarin anticoagulant therapy. Conclusions When start antiepileptic treatment in relevant basic diseases of symptomatic epilepsy, for a variety of combination reactions, AEDs can affect the anticoagulant effect of warfarin, so we need to consider the interaction between drugs and avoid adverse reactions.
ObjectiveIn order to evaluate the efficacy, safety and tolerability of adjunctive perampanel in children with refractory epilepsy. MethodsThis study collected medical records of 34 children with refractory epilepsy, who were admitted to Children’s Hospital of Soochow University from January 2020 to January 2021. By comparing the baseline status with the status at 4, 8, 12, 24, 36, and 48 weeks of follow-up, the efficacy and adverse reactions of perampanel were evaluated. ResultsThe mean age of the patients treated with perampanel was 8.1±4.1 years. The male-to-female ratio was 1: 1. After the addition of perampanel, the average responder rate at the 4th, 8th, 12th, 24th, 36th, 48th weeks were 37.5%, 46.7%, 50.0%, 47.4%, 53.8%, 42.9%. The adverse events were reported by 32.4%, and the retention rate was 88.2%. ConclusionsPerampanel has good efficacy, safety and tolerability in the treatment of refractory epilepsy. Moreover, personalized treatment and better baseline seizure control may increase the effectiveness and retention rate of perampanel.
Objective To study the efficacy and adverse events of adjunctive perampanel in children with refractory epilepsy. Methods A prospective study was carried out in 45 children with refractory epilepsy, who were treated in our hospital from January 2020 to February 2021 using perampanel as an add-on treatment, with a criteria for enrollment and the starting dose of perampanel. Follow-up would be taken at once a month. Afte 3 months would check blood routine, liver function, kidney function and humoral immunity. The EEG was reviewed after 6 months. The initial dose of perampanel was 0.04 mg/(kg·d) (the maximum didn't exceed 2 mg/d), increasing by 0.04 mg/(kg·d) every two weeks, and the maximum maintenance dose didn't exceed 6 mg/d. The efficacy and adverse reactions of perampanel were evaluated by comparing the seizure frequency and EEG results before and after a 6-month add-on therapy.ResultsAmong the 45 children,complete seizure control was achieved in 7 cases after the therapy, and the seizure attacks were reduced in 26 cases, showing a total response rate of 73.3%. After the treatment, the epileptiform discharge of 28 children was reduced, and the effective rate was 62.22%. During the observation period, all the blood routine, liver function, kidney function,and humoral immunity of the children were normal.10 cases of adverse reactions occurred after the additional treatment of perampanel, and the adverse reaction rate was 22.22%. Conclusions Perampanel has good efficacy and safety in the add-on treatment of refractory epilepsy.
Objective To explore the clinical efficacy of levetiracetam (LEV) in preventing recurrence of complex febrile seizures. Methods 100 children with complex febrile seizures who visited Wuxi Children's Hospital from January 2017 to January 2020 were randomly divided into two groups, observation group (n=50, treated with oral LEV), including 28 males and 22 females, with an average age of (1.57±0.42) years; control group (n=50, treated with oral diazepam), including 26 males and 24 females, with an average age of (1.58±0.39) years. The incidence of adverse reactions, the recurrence rate, EEG changes and neural development after the treatment in both groups were observed. Results After treatment, the incidence of adverse reactions in the observation group was 4.00%, which was significantly lower (P<0.05) than that in the control group (18%). The recurrence rate of the observation group was 2.00%, which was significantly lower (P<0.05) than that in the control group (14%). The incidence of abnormal EEG in the two groups after treatment was lower than that before treatment (P<0.05), but there was no significant difference between the two groups (P>0.05). The results of neurodevelopmental assessment in both two groups were in the normal range before and after treatment, and there was no significant change (P>0.05). Conclusions LEV is effective in the treatment and prevention of complex febrile seizures recurrence, with high safety, less adverse reactions and improved prognosis.
Valproic acid can reduce the frequency of seizures through various mechanisms and is widely used in clinical practice as a monotherapy or adjunctive treatment for various types of epilepsy and epileptic syndromes. In addition, valproic acid has significant therapeutic effects on comorbidities associated with epilepsy, such as migraines and psychiatric disorders. It can also be effective in terminating status epilepticus and is commonly used as a broad-spectrum antieseizure medication in clinical settings. However, valproic acid has side effects such as teratogenicity, infertility, and menstrual disorders. Additionally, when used in combination with other drugs, the interactions between medications should be carefully considered. Therefore, in clinical practice, it is necessary to strictly adhere to the indications and dosage regimens for the use of valproic acid. This article provides a comprehensive review of the use of valproic acid in different types of seizures, epileptic syndromes, comorbidities associated with epilepsy, post-craniotomy cases, status epilepticus, and special populations. It also summarizes the combination therapy of valproic acid with other drugs, providing a basis for the rational use of valproic acid and individualized drug treatment selection for epilepsy patients.
