ABSTRACT

Background: Migraine is a most common and highly prevalent neurologic disorder characterized by recurrent moderate-to-severe headaches often in association with a number of autonomic nervous system symptoms. Sodium valproate and topiramate are the two newer antiepileptic agents which are commonly prescribed for the migraine prophylaxis in India. Aims and Objectives: The aims of the study were as follows: (1) To compare the efficacy of sodium valproate 15–30 mg/kg/day and topiramate 2–3 mg/kg/day as prophylactic therapy for migraine in adults and (2) to study cost-effectiveness and safety profile of sodium valproate and topiramate. Materials and Methods: It is an open-label comparative study; 100 migraine patients of age group between 20 years and 50 years of both sexes were enrolled in the present study according to the inclusion criteria. Patients were diagnosed as migraine as per the International Criteria For Headache Disorders-3. Before starting treatment and after diagnosis, investigations have done, that is, complete blood picture, liver function test, renal function test, random blood sugar, and thyroid profile. Randomization was done by choosing every alternate patient and study drugs were prescribed. One hundred patients were divided into two groups, Group-A: 50 patients administered Tab. sodium valproate 500 mg twice daily orally and Group-B: 50 patients administered Tab. topiramate 150 mg once daily orally for a period of 6 months. Results: In Group-A, the severity of pain value before starting treatment was 6.440 ± 2.130 which is reduced to 1.820 ± 1.024 at the end of the treatment which was statistically significant (P < 0.0001) and the frequency of headache value before starting treatment was 4.220 ± 1.298 which is reduced to 1.320 ± 0.7407 at the end of the treatment, P < 0.0001 which was statistically significant. In Group-B, the severity of pain value before starting treatment was 6.200 ± 2.119 which is reduced to 1.840 ± 0.9765 after starting treatment which was statistically significant (P < 0.0001) and the frequency of headache value before starting treatment was 4.300 ± 1.199 which is reduced to 1.340 ± 0.6884 after starting treatment, P < 0.0001 which was statistically significant. In between the two groups severity of migraine pain and headache frequencies the P value was statistically significant. Conclusion: The results of the present study demonstrated that both sodium valproate and topiramate were well tolerated, having similar efficacy in reducing the severity of the pain, headache frequencies, and improving the quality of life. Sodium valproate is preferred because of cost-effectiveness.

ABSTRACT

OBJECTIVES@#To study the effect of early use of sodium valproate on neuroinflammation after traumatic brain injury (TBI).@*METHODS@#A total of 45 children who visited in Xuzhou Children's Hospital Affiliated to Xuzhou Medical University from August 2021 to August 2022 were enrolled in this prospective study, among whom 15 healthy children served as the healthy control group, and 30 children with TBI were divided into a sodium valproate treatment group and a conventional treatment group using a random number table (n=15 each). The children in the sodium valproate treatment group were given sodium valproate in addition to conventional treatment, and those in the conventional group were given an equal volume of 5% glucose solution in addition to conventional treatment. The serum concentrations of nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3), high-mobility group box 1 (HMGB1), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) were measured in the healthy control group on the day of physical examination and in the children with TBI on days 1, 3, and 5 after admission. Glasgow Outcome Scale-Extended (GOS-E) score was evaluated for the children with TBI 2 months after discharge.@*RESULTS@#Compared with the healthy control group, the children with TBI had significantly higher serum concentrations of NLRP3, HMGB1, TNF-α, and IL-1β on day 1 after admission (P<0.017). The concentration of NLRP3 on day 5 after admission was significantly higher than that on days 1 and 3 after admission in the children with TBI (P<0.017). On days 3 and 5 after admission, the sodium valproate treatment group had a significantly lower concentration of NLRP3 than the conventional treatment group (P<0.05). For the conventional treatment group, there was no significant difference in the concentration of HMGB1 on days 1, 3, and 5 after admission (P>0.017), while for the sodium valproate treatment group, the concentration of HMGB1 on day 5 after admission was significantly lower than that on days 1 and 3 after admission (P<0.017). On day 5 after admission, the sodium valproate treatment group had a significantly lower concentration of HMGB1 than the conventional treatment group (P<0.05). For the children with TBI, the concentration of TNF-α on day 1 after admission was significantly lower than that on days 3 and 5 after admission (P<0.017). On days 3 and 5 after admission, the sodium valproate treatment group had a significantly lower concentration of TNF-α than the conventional treatment group (P<0.05). The concentration of IL-1β on day 3 after admission was significantly lower than that on days 1 and 5 after admission (P<0.017) in the children with TBI. On days 3 and 5 after admission, the sodium valproate treatment group had a significantly lower concentration of IL-1β than the conventional treatment group (P<0.05). The GOS-E score was significantly higher in the sodium valproate treatment group than that in the conventional treatment group 2 months after discharge (P<0.05).@*CONCLUSIONS@#Early use of sodium valproate can reduce the release of neuroinflammatory factors and improve the prognosis of children with TBI.

ABSTRACT

Objective:To investigate the role and mechanism of sodium valproate (VPA) in cardiac and cerebral injuries after cardiopulmonary resuscitation (CPR) in pigs.Methods:Twenty-five healthy male domestic pigs, weighing (37±3) kg, were randomly divided into the sham group ( n=6), CPR group ( n=10), and CPR+VPA group ( n=9). Cardiac arrest was induced by alternating current delivered via a pacing catheter in the right ventricle and untreated for 9 min, and then CPR was performed for 6 min, in which this procedure was used to establish the animal model of cardiac arrest and CPR. At 5 min after resuscitation, a dose of 150 mg/kg of VPA was infused with a pump via the femoral vein in 1 h in the CPR+VAP group. At 1 h, 2 h, 4 h and 24 h after resuscitation, blood samples were drawn from the femoral vein, and then used to measure the serum concentrations of cardiac troponin I (cTnI), creatine kinase MB (CKMB), neuron specific enolase (NSE), and S100B protein (S100B) by ELISA. At 24 h after resuscitation, the animals were euthanized, and then tissue specimens in the left myocardium and brain cortex were rapidly harvested to detect the expression levels of C/EBP homologous protein (CHOP), caspase 12, and caspase 3 by Western blot, and the rate of apoptotic cells was detected by TUNEL. Continuous variables were compared with one way analysis of variance among the three groups. Results:(1) After resuscitation, cardiac and cerebral injury biomarkers including cTnI, CKMB, NSE, and S100B in serum were significantly increased in the CPR and CPR+VPA groups compared with the Sham group (all P<0.05). The serum concentrations of cTnI and NSE starting 1 h after resuscitation and the serum concentrations of CKMB and S100B starting 2 h after resuscitation were significantly decreased in the CPR+VPA group compared to the CPR group (all P<0.05). (2) Those proteins related to cell apoptosis mediated by endoplasmic reticulum stress, including CHOP, caspase 12, and caspase 3, were significantly increased, and meanwhile apoptosis index was markedly elevated after resuscitation in the CPR and CPR+VPA groups compared with the Sham group (all P<0.05). Nevertheless, the expression levels of CHOP, caspase 12, and caspase 3 were significantly decreased, and cell apoptosis was markedly reduced in the heart and brain after resuscitation in the CPR+VPA group compared to the CPR group (all P<0.05). Conclusions:VPA can alleviate cardiac and cerebral injuries after CPR in pigs, and its mechanism may be possibly related to the inhibition of cell apoptosis mediated by endoplasmic reticulum stress.

ABSTRACT

The rational use of medicine is fundamental to ensure effective and safe patient medicine treatment, and hence, should be monitored. Undisputable evidence exists for the teratogenic risk factors associated with sodium valproate. Consequently, the Western Cape Department of Health introduced a policy (2019) recommending alternatives for valproate in women of childbearing age, including lamotrigine or levetiracetam as alternatives for patients on antiretrovirals. This study aimed to describe the change in the consumption of valproate, lamotrigine and levetiracetam after a policy implementation in public sector health facilities of the Western Cape, South Africa. Methods: This observational study followed a quasi-experimental design. Consumption data from the Cape Medical Depot over the period 01 April 2018 to 31 March 2020 were analysed retrospectively. Consumption was presented as a defined daily dose (DDD) per 1000 population per quarter for sodium valproate, levetiracetam and lamotrigine for the Western Cape province, urban and rural areas. Consumption 12 months before was compared with consumption 12 months after policy implementation. Results: Post-policy implementation, valproate consumption remained unchanged provincially (3.3%; p = 0.255), in urban (7.8%; p = 0.255) and rural (1.5%; p = 0.701) areas. Lamotrigine consumption increased significantly provincially (30.7%; p = 0.020) and in urban areas (54.5%; p = 0.002); however, rural (26.1%; p = 0.108) areas did not show significant change. Provincially, valproate consumption remained substantially higher (209 DDDs/1000 population per quarter) compared with lamotrigine consumption (32.22 DDDs/1000 population per quarter). Conclusion: In the Western Cape public sector, the consumption of sodium valproate remained unchanged 12 months after policy implementation. Although there were significant increases in lamotrigine and levetiracetam consumption, the consumption was considerably less compared with sodium valproate consumption.

ABSTRACT

Objective To establish a high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method for simultaneous determination of sodium valproate and vancomycin in human serum. Methods Valproic acid-d6 and kanamycin B were used as the internal standard of sodium valproate and vancomycin, the serum samples were treated by acetonitrile precipitation protein method. The mobile phase was 0.1% formic acid aqueous solution-acetonitrile for gradient elution. The flow rate was 0.5 ml/min, with column temperature at 25 ℃. The sample volume was 4 μl and total analysis time was 12 min. The positive and negative ion mode was monitored by electrospray ion source and the multiple reaction monitoring mode was used for quantitative analysis. The specificity, standard curve, lower limit of quantification, precision, recovery, matrix effect, and stability of the method were examined. Results Sodium valproate and vancomycin had good linear relationships in the range of 1 - 200 μg/ml and 0.5 - 100 μg/ml, respectively. The quantitative lower limits were 1 μg/ml and 0.5 μg/ml, respectively. The extraction recoveries were above 70%. The inter- and intra-batch precision RSD values were less than 10%. The stability was good and there was no obvious matrix effect. Conclusion This method is simple, quick, sensitive, specific and accurate, which could be used to simultaneously determine the concentration of sodium valproate and vancomycin in human serum.

ABSTRACT

OBJECTIVE To study the protective effects o f valproic acid on cardiac and cerebral injury in rats subjected to severe scalding combined with seawater immersion injury with delayed fluid replacement. METHODS The rats were divided into scalding+delayed fluid replacement group (group S ),scalding+seawater immersion+delayed fluid replacement group (group SS ), scalding+seawater immersion+valproic acid+delayed fluid replacement group (group SSV )according to random number table ,with 60 rats in each group. All groups were subjected to 35%total body surface area third-degree full-thickness scalding with boiled water. Group SS and group SSV were immersed in artificial ;seawater(30 min)immediately after scalding ,and group SSV was subcutaneously injected with valproic acid 300 mg/kg immediately after out of water. Sodium lactate Ringer ’s 0314-2279277。E-mail:125467374@qq.com injection was injected intravenously within 30 minutes according to 1/2 Parkland formula at 2 h after scalding in each group for delayed fluid replacement. The death time of rats was recorded ,and the average survival time and 24 h survival rate of rats in each group were calculat ed. Mean arterial pressure (MAP),heart rate (HR),respiration rate (RR),rectal temperature (RT),arterial blood pH ,arterial partial pressure of oxygen (PaO2),arterial blood partial pressure of carbon dioxide (PaCO2),HCO3-,creatine kinase MB isoenzyme (CK-MB)and neuron specific enolase (NSE)were detected before scalding ,at 0,2,5 h after scalding. The pathological changes of cardiac and cerebral tissue were observed. RESULTS The 24 h survival rate of group SS (55%)was significantly lower than that of group S (90%), while that of group SSV (75%)was increased significantly ,compared with group SS (P<0.05). Compared with group S ,the levels of MAP ,RT,HR,pH,PaO2 and HCO 3- in group SS were significantly lowered ,while the levels of CK-MB and NSE were increased significantly at 0,2,5 h after scalding ;the levels of PaCO 2 were increased significantly at 2,5 h after scalding , while the levels of RR were decreased significantly at 0,2 h after scalding (P<0.05). Compared with group SS ,the levels of MAP,RT,HR,pH,PaO2 and HCO 3- in group SSV were significantly increased ,while the levels of PaCO 2,CK-MB and NSE were decreased significantly at 2,5 h after scalding ;the level of RR was increased significantly at 2 h after scalding (P<0.05). At 2,5 h after scalding ,cardiac and cerebral injury of rats in group SS were aggravated significantly than that in group S ;cardiac and cerebral injury of rats in group SSV were relieved significantly than that in group SS.

ABSTRACT

Pediatric epilepsy comprises chronic neurological disorders characterized by recurrent seizures. Sodium valproate is one of the common antiseizure medications used for treatment. Glucuronide conjugation is the major metabolic pathway of sodium valproate, carried out by the enzyme uridine 5′-diphosphate (UDP) glucuronosyl transferase (UGT) whose gene polymorphisms may alter the clinical outcome. The objective of this study was to assess the association between UGT1A6 genetic polymorphism and clinical outcome in terms of efficacy and tolerability in pediatric epileptic patients on sodium valproate monotherapy. Pediatric epileptic patients (n=65) aged 2-18 years receiving sodium valproate monotherapy for the past one month were included. Genetic polymorphism patterns of UGT1A6 (T19G, A541G, A552C) were evaluated by PCR-RFLP. Clinical outcome was seizure control during the 6 months observation period. Tolerability was measured by estimating the hepatic, renal, and other lab parameters. Out of 65 patients, TT (40%), TG (57%), and GG (3%) patterns were observed in UGT1A6 (T19G) gene, AA (51%), AG (40%), and GG (9%) in (A541G) gene, and AA (43%), AC (43%), and CC (14%) in (A552C) gene. No statistical difference in clinical outcome was found for different UGT1A6 genetic polymorphism patterns. We concluded that different patterns of UGT1A6 genetic polymorphism were not associated with the clinical outcome of sodium valproate in terms of efficacy and tolerability. Sodium valproate was well-tolerated among pediatric patients with epilepsy and can be used as an effective antiseizure medication.

ABSTRACT

Objective: Sodium valproate granules (VPA granules) are extremely hygroscopic, deliquesce slowly in the air, and aggregate depending on temperature and humidity conditions. Although pharmacists are required to maintain drug storage conditions until the time of dispensing, they cannot keep track of the actual storage conditions maintained by the patients thereafter. Therefore, we investigated the actual temperature and humidity of the storage conditions maintained by the patients after delivery of the VPA granules.Methods: We conducted a prospective observational study at Kameda Medical Center on pediatric outpatients who were prescribed VPA granules from July 5, 2018 to February 20, 2019. A portable data logger capable of measuring temperature and humidity for 24 h was delivered at the time of dispensation. At the following visit, the data logger was collected, and data about temperature and humidity were obtained. We defined the suitable temperature as 1.0-30.0℃ and suitable humidity as 75.0% or less.Results: In this study, 13 patients were included. In total, 18 data loggers were distributed, and the return rate was 100.0%. The storage temperature was outside the suitable range in 0.8% of the total observation time whereas the humidity exceeded 75.0% in 1.7% of the total observation time.Conclusion: Storage of medications after dispensation was evaluated, and certain temperature and humidity deviations were observed. As storing a drug in an inappropriate environment changes the nature of the drug, affecting its efficacy and safety, it is necessary to educate patients on the proper methods to store oral medications.

ABSTRACT

Objective To explore the role of clinical pharmacists in the treatment of drug poisoning by analyzing the clinical pharmacist's participation in the treatment of a patient with sodium valproate poisoning. Methods Clinical pharmacists measured the plasma concentration of sodium valproate to inform the doctor to diagnose illnesses. At the initial stage when the concentration is high, to eliminate the free drug by continuous venous-venous hemodialysis-filtration (CVVHDF). Then, the combined drug was cleared by hemoperfusion (HP). Results The blood concentration dropped by half at the first CVVHDF and decreased obviously after two HPs. After stable observation in five days’ course of disease, the blood concentration was maintained at a low level and the patient was cured and discharged. Conclusion The implementation of the blood purification program under the monitoring of the blood drug concentration with the participation of pharmacists is helpful for the rescue of drug overdose and is worthy of promotion.

ABSTRACT

Background: Presently available antiepileptic drugs are effective in controlling seizures in more than half of patients of all epilepsy but use is often limited by adverse effects. H1 receptor antagonists, have a controversial status in patients of epilepsy. Both pro and antiepileptic effect has been documented in various animal studies. Hence, this study was designed to see the effect of promethazine, an H1 antihistaminic drug and its interactions with antiepileptic drugs lorazepam and sodium valproate in rats.Methods: The effect of promethazine (10 mg/kg) and its interactions with antiepileptic drugs lorazepam and sodium valproate was assessed by using maximal electroshock seizures (MES) and chemoshock pentylenetetrazol (PTZ) method.Results: Promethazine along with lorazepam and sodium valproate in subtherapeutic doses exerted significant protection against MES induced seizures whereas no such protection was observed with PTZ method rather the seizure threshold was reduced.Conclusions: Subtherapeutic doses of promethazine alone and in combination with lorazepam and sodium valproate showed protection against seizures in MES method. However, proconvulsant effect was seen with PTZ method. This shows dual behavior of promethazine on MES and PTZ induced seizures.

ABSTRACT

OBJECTIVE: To compare all published sodium valproate population pharmacokinetic models of epileptic children in China and assess them by external validation to determine their predictive performance. METHODS: The published population pharmacokinetic model of sodium valproate in children with epilepsy in China was collected by database retrieval. By retrospectively collecting patients' information, we performed an external validation to evaluate the power of prediction. RESULTS: Four sodium valproate models were published before. The external validation of 101 samples showed that the MPE, MAE, RMSE of the four model were similar. All of them showed good adequacy between predicted concentrations and observed concentrations. Comparing with other models, the model established by Ding has better prediction error coincidence rate in most interval, which is more targeted for the prediction of individualized dosage regimen for epileptic children in our hospital. However, the overall prediction accuracy of the four models is not significantly different. CONCLUSION: By the evaluation of four published population pharmacokinetic models of sodium valproate model B performs better than others, while the overall accuracy of the four models did not differ much. Racial difference may be an important factor affecting the accuracy of the model, which needs to be further explored in subsequent studies.

ABSTRACT

OBJECTIVE:To reference for the rational use of sodium va lproate in clinic. METHODS :By retrospective analysis,blood concentration monitoring results of sodium valproate and medical record data in 856 patients were collected from the Affiliated Tianyou Hospital of Wuhan University of Science and Technology during Jan. 2016-Dec. 2018. The dosage form of sodium valproate ,monitoring times of therapeutic drugs ,monitoring results of steady-state blood concentration of sodium valproate up to the standard ,dosage adjustment and the combination with carbamazepin ,fluconazol and carbapenem drugs were analyzed. Fisher exact test was used to analyze the factors influencing the steady-state blood concentration of sodium valproate up to the standard. RESULTS :A total of 1 270 cases of sodium valproate were monitored in 856 patients,involving 407 males and 449 females,with age of (38.2±13.8)years and body mass of (52.3±10.0)kg. Among 1 270 cases of monitoring ,steady-state blood concentration of sodium valproate in 554 cases were in the range of 50-100 µg/mL,and 43.6% of which reached the standard. The rate of reaching the standard in patients with multiple monitoring was higher than patients with single monitoring ;the dosage of patients with last monitoring reaching the standard was higher than that of patients with the first monitoring reaching the standard. The rate of reaching the standard in Sodium valproate sustained-release tablet group was higher than general Sodium valproate tablet group;the carbamazepin/fluconazol free group was higher than the carbamazepin combination group and fluconazol combination group;the carbapenem free group was higher than the carbapenem combination group (all P<0.05). CONCLUSIONS :Clinical pharmacists should pay attention to the monitoring of sodium valproate treatment drugs , strengthen the publicity and 3551851542@qq.com education of patients and their families ,and try to use Sodium valproate sustained-release tablets. When patients additionally receive carbapenem drugs like carbamazepin or fluconazol , the standard level of sodium valproate will be reduced ,then the dosage of sodium valproate should be adjusted.

ABSTRACT

Background: Generic substitution is preferred to reduce healthcare costs and improve patient adherence. The review of literature showed that physicians all around the world were not comfortable in prescribing generic medications due to the lack of evidence on their safety and efficacy.Methods: A prospective study was conducted over a period of one year in Pune. The patients were categorized on their age and were assessed for the clinical effectiveness data (no. of breakthrough seizures and seizure free days) and safety data (no. of ADR episodes). The mean number of patients controlled and the frequency of adverse events at the 3rd and 6th month were calculated.Results: Authors assessed 150 newly diagnosed pediatric epileptic patients who received anti-epileptic drug monotherapy for at least 6 months, out of which 46 (30.66%) received Oxcarbazepine and 104 (69.33%) received Sodium Valproate. At the end of 3 months of therapy 140 (93.33%) patients were seizure free and 145 (96.66%) patients were seizure free at the end of 6 months. Adverse effects were observed in 14 (30.43) patients on oxcarbazepine and 26 (25%) patients on sodium valproate. The most common adverse effect was weight gain in 34 (22.66%) patients with both the AEDs.Conclusions: Seizure control was achieved in majority of the patients. In addition to the seizure control, the frequency of adverse effects was few and tolerable by the patients when prescribed with low cost branded generics.

ABSTRACT

Background: Epilepsy is a disorder characterised by recurrent seizures of cerebral origin with episodes of sensory, motor phenomenon with or without loss of consciousness. The present study was taken up to evaluate the anticonvulsant effect of aqueous extract of leaves of Adhatoda vasica in rats. Objectives of this study is to evaluate the effect of aqueous extract of Adhatoda vasica leaves on Pentylenetetrazol induced seizures in albino rats and to compare the effect of aqueous extract of Adhatoda vasica leaves with standard dose of sodium valproate on Pentylenetetrazol induced seizures in albino rats.Methods: Anticonvulsant activity of aqueous extract of Adhatoda vasica was analysed using PTZ (Pentylenetetrazol) model. Groups used were distilled water as control group, Sodium valproate as standard for Pentylenetetrazol and two doses of aqueous extract of Adhatoda vasica (100mg/kg and 200 mg/kg) for this screening model. Parameters observed for PTZ models were abolition of clonic seizures and time duration between injection of PTZ and onset of seizures.Results: In PTZ model, test group at 200 mg/kg showed 33.33% protection for abolition of clonic seizures, though not comparable to standard group. There was significant increase in the duration of onset of clonic seizures after PTZ injection in both test groups (at 100 mg/kg and 200 mg/kg) when compared to control group.Conclusions: Aqueous extract of leaves of Adhatoda vasica has shown significant anticonvulsant action in PTZ model.

ABSTRACT

Introduction: Sodium valproate is an anticonvulsantwidely prescribed as a mood stabilizer for treating bipolardisorders. It’s role in treating schizoaffective disorders iswell documented. There are controversies regarding sodiumvalproate efficacy in schizophrenia. Although, some studieshave reported that it is effective in the management of positivesymptoms in acute psychosis, others have not found such anassociation. Study aimed at assessment the effect of adjunctivesodium valproate in acute stage of schizophrenia.Material and Methods: A total of 60 schizophrenic patients(age 18-45 years) were taken. They were randomly allocatedinto two groups, A and B. Patients in group A receivedatypical antipsychotic with placebo and in group B atypicalantipsychotic with adjunctive sodium valproate. Olanzapinewas taken as atypical antipsychotic in both groups.A diagnosis of schizophrenia was established based on ICD10 DCR criteria. All patients were assessed by PANSS andCGI-S at baseline and at 6 weeks. The collected data wereanalyzed by Student and Paired t-tests through SPSS.Results: Comparison of mean PANSS scores showedstatistically significant improvement in positive symptoms(p<0.014), general psychopathology (p<0.036) and total score(p<0.018) in group B patients as compared to group A. CGI-Sscores were also statistically significantly less in (p<0.011)group B patients as compared to group A after 6 weeks.Conclusion: Our study shows that if used as an adjunctive toantipsychotic in the management of acute psychosis, sodiumvalproate will speed up the recovery of positive symptoms

ABSTRACT

Objective Few studies are reported on the protective effect of valproic acid (VPA) against traumatic brain injury (TBI) by down-regulating the protein expressions of matrix metalloproteinase-9 (MMP-9) and aquaporin-4 (AQP-4) in the brain tissue. This study aimed to investigate the neuroprotective effects of different doses of VPA against TBI in experimental rats. Methods We randomly divided 100 adult male rats into five groups of equal number, sham operation, TBI model, and low- (30 mg), medium- (150 mg) and high-dose (300 mg) VPA treatment. At 1, 3, 7 and 14 days after modeling by controlled cortex impact, we obtained the modified Neurological Severity Scores (mNSS), measured the VPA concentration in the venous blood, and then killed the rats and harvested the brain tissue for determination of the water content using the dry-wet method and the expressions of MMP-9 and AQP-4 by Western blot and immunohistochemistry. Results At 1, 3, 7 and 14 days after modeling, the mNSSs in the high-dose VPA group were 4.6 ± 1.3, 3.8 ± 1.3, 3.0 ± 0.7 and 1.8 ± 0.8, respectively, significantly lower than 8.4 ± 0.9, 7.0 ± 0.7, 5.8 ± 1.0 and 4.5 ± 1.3 in the TBI group (P < 0.05), decreasing in a time-dependent manner, with statistically significant difference between any two dose groups (P < 0.05). At 1, 3 and 7 days, the water contents in the brain tissue were (76.2 ± 0.7)%, (76.9 ± 1.7)% and (73.9 ± 1.3)% in the high-dose VPA group, significantly lower than (79.6 ± 0.8)%, (82.6 ± 0.8)% and (78.6 ± 0.7)% in the TBI group (P < 0.05), also decreasing in a time-dependent manner, with statistically significant difference between any two dose groups (P < 0.05). At 1 and 3 days, the expressions of MMP-9 and AQP-4 in the brain tissue were markedly down-regulated in the VPA groups in a dose-dependent manner as compared with those in the TBI group (P < 0.05), with statistically significant difference between any two dose groups (P < 0.05), and meanwhile immunohistochemistry showed large numbers of cells with positive expressions of MMP-9 and AQP-4, which were reduced with the increased dose of VPA. Conclusion VPA has a neuroprotective effect against TBI in rats by inhibiting the expressions of MMP-9 and AQP-4 proteins in the brain tissue and alleviating brain edema. Within the range of the doses studied, higher-dose VPA produces a better effect.

ABSTRACT

Objective To explore and compare the clinical efficacy of levetiracetam tablets and compound sodium valproate sustained release tablets in the treatment of children and adolescents with epilepsy.Methods From April 2017 to April 2018,80 children and adolescents with epilepsy treated in Chaonan Minsheng Hospital of Shantou were selected as study objects,and they were randomly divided into two groups by drawing lots,with 40 cases in each group.The observation group was given levetiracetam tablets,and the control group was treated with valproate.The improvement of EEG after therapy,the total effective rate,and the incidence of adverse reactions were observed and evaluated.Results The EEG improvement rates after treatment for 6 months in the observation group and control group were 41.17%,45.71%,respectively,the difference was not statistically significant(x2 =0.508,P >0.05).The EEG improvement rates after treatment for 9 months in the observation group and control group were 70.58%,74.28%,respectively,the difference was not statistically significant (x2 =0.225,P > 0.05).The total effective rate in the observation group was 92.50%,which was 95.00% in the control group,the difference was not statistically significant between the two groups (x2 =0.354,P > 0.05).However,the incidence rate of adverse reactions of the observation group(22.50%) was significantly lower than that of the control group(45.00%)(x2 =6.864,P < 0.05).Conclusion Both levetiracetam tablets and compound sodium valproate sustained release tablets have appreciable efficacy and safety in the treatment of epilepsy in children and adolescents,but levetiracetam therapy has less adverse reactions,which deserves further promotion in monotherapy of epilepsy in children and adolescents.

ABSTRACT

Background: Sodium valproate is an anti-seizure drug used for prophylactic use of migraine headaches. Despite the efficacy of this drug due to complications that cause some patients to not tolerate the drug. The purpose of this study was to Comparison of levotiracetam and Sodium valproate in migraine prophylaxis.Methods: This is a clinical trials study. 100 migraineurs who referred to the Alavi neurology clinic and indicated the onset of prophylaxis of migraine were studied in two groups of 50, one of which was a group of levetiracetam and another group of sodium valproate Received. Patients received daily 500mg of drug for 3 months and the effect of the drug on the number of attacks, severity of attacks, and MIDAS score was measured. Collected data analyzed by statistical methods in SPSS version 19. P<0.05 was considered as significant.Results: In both cases, significant improvement was observed in the number of attacks, severity and MIDAS score. In all of the criteria, levetiracetam and sodium valproate were almost identical, except for reducing the number of headache attacks that had a significantly in levothyramine group less than sodium valporoste group (P = 0.0001).Conclusions: This study showed that levothyramineacetamin can be used as a good alternative in those who do not tolerate sodium valproate.

ABSTRACT

Background: Many antiepileptic drugs were introduced for the treatment of epilepsy. Ideal antiepileptic drug should not only prevent but also correct the underlying pathophysiology without altering the normal neurotransmission. Calcium channel blockers may form such group because initiation of seizure is associated intrinsic burst firing which is triggered by large inward calcium current, so this study was done to evaluate the anticonvulsant effect of amlodipine in albino rats.Methods: A total of 42 adult albino rats were included in the study and divided into 7 groups, each containing 6 rats. Group 1 received distilled water, group 2,3 received sodium valproate 50mg/kg and 100mg/kg, group 4-6 received amlodipine 1, 2, 4mg/kg and group 7 received combination of Amlodipine 1 mg/kg and sodium valproate 50mg/kg. Pentylenetetrazole induced seizures model was done and onset of myoclonic jerks, onset of clonic convulsions and duration of clonic convulsions was studied.Results: There was a significant anticonvulsant effect in Amlodipine doses 2, 4mg/kg (p <0.001). The combination of Amlodipine (1mg/kg) and Sodium valproate (50mg/kg) also had significant anticonvulsant effect.Conclusions: Amlodipine, a calcium channel blocker has anticonvulsant effect and also potentiated the anticonvulsant effect of low dose sodium valproate.

ABSTRACT

Objective: To investigate the effects of sodium valproate (VPA) on the expression of FAK and FAK-pY397 in hippo-campus of rats with seizure induced by pentylenetetrazole (PTZ). Methods: A total of 75 rats were randomly divided into 5 groups:the normal control group, the epilepsy model group (PTZ group) and the VPA groups(150,300 and 600 mg·kg-1·d-1)with 15 ones in each group. The model rats were continuously given PTZ (32 mg·kg-1·d-1) by intraperitoneal injection for 4 weeks and paid close attention to the behavioral changes, and then VPA was administrated orally for 2 weeks. The pathological changes of hippo-campus tissue were observed by HE staining. The expressions and distributions of FAK, FAK-pY397 and integrin in serum and hippo-campus were evaluated by immunohistochemical assay and enzyme-linked immunosorbent assay (ELISA). Results: Compared with the model group, the symptoms of epilepsy in VPA groups were significantly relieved and cell apoptosis was improved. Immunohistochemis-try showed that the expression of FAK-pY397 decreased significantly in VPA groups with the increase of sodium valproate dose, and there was no significant difference in the expression of ITGα3. The VPA groups significantly reduced the expression of FAK, FAK-pY397 and ITGβ1(P<0. 05), the expression of FAK and ITGβ1 protein in peripheral serum decreased significantly (P<0. 05), but the expression of FAK-pY397 did not change significantly. Conclusion: VPA can effectively participate in or affect the process of epi-lepsy by inhibiting the expressions of FAK-pY397 and ITGβ1 in hippocampal tissue of epileptic rats.
