Dark-purple rice extract modulates gut microbiota composition in acetic acid– and indomethacin-induced inflammatory bowel disease in rats / El extracto de arroz púrpura oscuro modula la composición de la microbiota intestinal en la enfermedad inflamatoria intestinal inducida por ácido acético e indometacina en ratas

Ulcerative colitis (UC) and Crohn’s disease (CD) are two major forms of inflammatory bowel disease (IBD). The disease has been linked with gut microbiota dysbiosis in which the balance of commensal communities is disrupted. Accumulating evidence demonstrates that treatment with biologically active compounds can modulate gut microbiota composition in animal models. Our previous work has also shown the beneficial effect of Luem Pua (LP) rice extract, which is rich in anthocyanins, on inflammation. However, its effect on gut microbiota is yet to be explored. In this study, we profiled fecal microbiota of acetic acid (AA)–induced UC and indomethacin (ID)–induced CD rat models with and without pretreatment with LP rice extract by 16S rRNA gene sequencing. The results showed that gut microbiota communities of rats were altered by both AA-induced UC and ID-induced CD. The relative abundances of beneficial bacteria, especially the Lachnospiraceae NK4A136 group and Lactobacillus, were decreased in the AA-induced UC model, while some opportunistic pathogens (Bacteroides, Escherichia/Shigella, Fusobacterium, and Veillonella) were raised by ID-induced CD. Interestingly, pretreatment with LP rice extract before AA-inducing UC in rats increased the proportion of the butyrate-producing bacteria (Lachnospiraceae NK4A136 group). The abundances of these beneficial bacteria and other SCFA-producing bacteria were unaffected by the indomethacin treatment with LP. Overall, our study revealed different impacts of AA-induced UC and ID-induced CD on changes in community composition and hinted at how LP may protect against UC by modifying the gut microbiota.(AU)

Efficacy of Generic Atorvastatin in a Real-World Setting.

BACKGROUND: The ability of statins to reduce LDL-c plays an important role in both primary and secondary prevention of atherosclerotic cardiovascular diseases. Such treatment can often be costly, but using generic atorvastatin may reduce cost by up to US$2635. In addition, a previous 8-week study found that it exhibited comparable efficacy to the brand-name medication. This study aimed to evaluate the efficacy of generic atorvastatin over a longer period of six months in a real-world setting. METHODS: This was a retrospective cohort study in adult patients who had received brand-name atorvastatin for at least three months and then had switched to generic atorvastatin for at least six months. Lipid and safety profiles were evaluated at six months after switching. Adjusted analyses for age, sex, co-morbid disease, dosage, and indications for statin therapy were also performed. RESULTS: During the study period, there were 488 patients who met the study criteria. The mean (SD) age of the patients was 60.97 (12.26) years, and 48.36% were male (236 patients). At six months, average total cholesterol, HDL-c, and LDL-c were all lower, from 174.43 to 166.15 mg/dL, from 51.64 to 49.51 mg/dL, and from 110.08 to 100.78 mg/dL (p < 0.001), respectively. There were no significant differences in terms of any other laboratory test results. LDL-c exhibited the highest significant reduction at 9.30 mg/dL. Stratified analyses by age, sex, co-morbid disease, dose, and indications for statin therapy revealed similar decreases in HDL-c and LDL-c as in the study population as a whole. CONCLUSION: Generic atorvastatin resulted in significantly lower LDL-c than name-brand atorvastatin but less of an increase in HDL-c.

Comparative pharmacodynamic effects of two clopidogrel formulations under steady-state conditions in healthy Thai volunteers
.

OBJECTIVE: Clopidogrel is a commonly used antiplatelet aggregation agent. Compared with the reference clopidogrel product, most commercially available generic clopidogrel products contain different crystalline forms of clopidogrel. This study was aimed to compare the pharmacodynamics of a commonly used generic clopidogrel product in Thailand with the reference clopidogrel product under steady state conditions. METHODS: A multiple-dose, randomized 2-way crossover study was conducted in 32 healthy male Thai volunteers. The subjects were assigned to receive 75 mg once daily of the test or the reference product for 7 days with a 2-week wash out period. Blood samples were collected on days 1, 5, 6, and 7 prior to drug administration and at 1, 2, 3, 4, 8, 12, and 24 hours after the last dose administered. The antiplatelet aggregation effects of clopidogrel were determined by using two different ex-vivo platelet aggregation tests including the whole blood impedance assay (WBA) and the VerifyNow® P2Y12 assay. Both pharmacodynamic parameters, the maximal antiplatelet effect (Emax) and the areas under the antiplatelet effect-time curve (AUEC0-24h), were calculated. RESULTS: Neither the mean values of Emax (90.70 ± 15.15 vs. 89.50 ± 10.71% inhibition) nor of AUEC0-24h (1,892.84 ± 657.22 vs. 1,853.58 ± 673.95% inhibition × h) under steady-state conditions obtained using the WBA method of these two clopidogrel products were significantly different. The results obtained using the VerifyNow® P2Y12 assay were consistent with those of the WBA assay. CONCLUSION: This study clearly demonstrated that ex-vivo antiplatelet aggregation effect under steady-state conditions of the test product was not significantly different from the reference product.

Effect of Andrographis paniculata Extract on Triglyceride Levels of the Patients with Hypertriglyceridemia: A Randomized Controlled Trial.

BACKGROUND: Hypertriglyceridemia is one of the risk factors for cardiovascular disease, and reduction oftriglyceride (TG) level is recommended in clinical practice guidelines for the treatment. Recently, andrographolide, a main active compound of Andrographispaniculata has been shown to possess hypolipidemic effects in animals. OBJECTIVE: To investigate the TG-lowering effects of A. paniculata extract (APE) in patients with hypertriglyceridemia (TG ≥ 150 mg/dL) using gemfibrozil treatment as the reference. MATERIAL AND METHOD: A randomized controlled clinical trial was carried out in sixty subjects with hypertriglyceridemia. They were divided into three groups and treated with low dose of APE (APE-L, andrographolide 71.64-72.36 mg/day), high dose of APE (APE-H, andrographolide 119.64-120.36 mg/day), and gemfibrozil 300 mg/day. The treatments were conducted for 8 weeks. Guidance on lifestyle modifications was provided. RESULTS: The primary endpoint was the mean difference ± SD (95% CI) in TG levels (baseline from the end of treatment), which were -3 ± 125.6 (-59.1, 58.5), 41.6 ± 86.3 (1.2, 82), and 57.1 ± 94.9 (12.7, 101.6) in the APE-L, APE-H, and gemfibrozil groups, respectively. APE-H 120 mg/day and gemfibrozil 300 mg/day caused a significant reduction of TG level (P = 0.0442 and 0.0145, respectively) when compared to the baseline. There was no notable difference in the safety or tolerability among the treatment groups. CONCLUSION: In patients with modest hypertriglyceridemia with lifestyle intervention, APE-H reduced the TG level comparable to the effect of gemfibrozil 300 mg/day. APE treatment was as tolerable as gemfibrozil treatment. Hence, Andrographis paniculata might be used as an alternative medicine in treating hypertriglyceridemic patients.

Predictive risk factors of seizure-related injury in persons with epilepsy.

OBJECTIVE: The clinical risk factors for seizure-related injuries (SRI) in adult persons with epilepsy (PWE) were studied and analyzed to develop a predictive model. METHODS: We enrolled 300 consecutive cases from three epilepsy clinics in Northeast, Thailand. Subjects were eligible if reported to have at least one seizure attack during the past 12 months. Face-to-face questionnaire was used to evaluate SRI, baseline characteristics and other seizure-related variables. RESULTS: There were 247 and 91 PWE who met a criterion and had SRI, respectively. By multivariate logistic regression method, GTC seizure type, having history of seizure attacks at least 12 times/year, and daytime seizure were significant risk factors of having SRI with odds ratio of 2.376, 2.460, and 3.562, respectively. We developed the predictive model for having SRI in PWE and it gave 90.3% sensitivity and 46.7% specificity on the occurrence of SRI. The estimated probability of SRI can be found online at http://sribykku.webs.com/. CONCLUSIONS: The significant predictive factors for SRI in PWE were the occurrence of GTCs, seizures at least 12 times/year or daytime seizures. Clinicians or PWE can easily evaluate the risk of having SRI in individuals by the online predictive model.

Very high dose phenobarbital for refractory status epilepticus.

BACKGROUND: Refractory status epilepticus (RSE), defined as status epilepticus that fails to respond to first, second and third-line therapy. The RSE is associated with high morbidity and mortality. Treatment guidelines of RSE give a spectrum of options, such as, continuous intravenous (i.v.) midazolam (MDL), or continuous i.v. propofol (PRO) as alternatives to phenobarbital (PB) or continuous i.v. pentobarbital (PTB). OBJECTIVE: To study the efficacy of very-high-dose phenobarbital (VHDPB) for treatment RSE. STUDY DESIGN: Retrospective study MATERIAL AND METHOD: The authors collected and analyzed data from adult patients who were diagnosed with RSE. RESULTS: The authors present 10 patients with RSE who were treated with VHDPB. All of them were generalized convulsive status epilepticus (GCSE). Ages ranged from 16-86 years old (mean.: 43 years). PB dosage ranged 40-140 mg/kg/day (mean: 70 mg/kg/day). The duration of status epilepticus (SE) varied widely, ranged 1-44 days (mean: 7 days). PB level ranged 35.29-218.34 ug/mL (mean 88.1 ug/mL). RSE was controlled by VHDPB 70%, 30% were not controlled. CONCLUSION: VHDPB were considered as alternative treatment for RSE.

Basic knowledge of epilepsy among medical students.

BACKGROUND: The medical students' knowledge about basic medical neuroscience in the preclinical level may be fragmented and incomplete. OBJECTIVE: Evaluate the knowledge of students prior to a lecture on epilepsy in clinical level. MATERIAL AND METHOD: One hundred ten fourth-year medical students' knowledge was accessed by a self-administered questionnaire. RESULTS: The presented results revealed that 91.8% of respondents knew that epilepsy arose from a transient dysfunction in the brain. Generalized tonic-clonic seizures (GTCs) were the most common type (91.5%) they knew and absence seizures were the least common type (33.6%) they knew. All of them knew that eating pork and punishment of gods did not cause epilepsy. However 50% thought that genetics was a cause and 80.3% did not know that stroke and sleep deprivation (92.7%) cause epilepsy. About treatment and prognosis, only 28.2% of respondents thought epilepsy can be cured and patients should take antiepileptic drugs (AEDs) for seizure free 2-5 years (48.2%), life long (33.6%). They knew that the patients should be prohibited from driving (80%), working on machinery (74.5%), and (27.3%) avoid drinking. However, they knew that the patients could marry (100%), get pregnant (98.2%), and lactate (91.9%). Regarding the first aid management, 50.9% of them recommended that placing a piece of wood between the teeth during a seizure and perform chest compressions (20.0%). Means knowledge scores is about 60%, the highest score is the definition of epilepsy (90.2%) and the lowest is type of seizure (43%). CONCLUSION: The findings indicated that lecturers should review aspects ofpathophysiology and emphasize on type of seizure, cause, consequences, and prognosis including first-aid management.

Knowledge of epilepsy among teachers in Khon Kaen Province, Thailand.

INTRODUCTION: Epileptic patients face social stigmatization due to negative attitudes and incorrect knowledge on epilepsy. OBJECTIVES: To evaluate knowledge of epilepsy among teachers in Khon Kaen province. MATERIAL AND METHOD: A self-administered questionnaire distributed to 102 teachers who attended the training lectures on epilepsy. The number of correct responses for each item were collected. The statistical analysis included the percentage of correct response and the means of the total scores. RESULTS: Most (78.4%) respondents understood that a seizure is an abnormal electrical discharge in the brain, while 54.9% thought it included a form of abnormal movement and 1% demonic possession. The generalized tonic-clonic seizure (GTCs) was the type of seizure with which most respondents were familiar (90.2%), while 23.5% had knowledge of absence seizures. The respondents identified the following as causes for epilepsy: 1) head injury (84%); 2) genetic disease (74.5%); 3) high fever (68%); and, 4) brain tumor (57%). A small minority associated epilepsy with eating pork (11%) and even fewer (2%) with a non-organic/non-physical cause. Only 16% of respondents thought epilepsy was incurable, and a quarter (27%) of the teachers thought epileptics required anti-epileptic drugs (AEDs) life long, while 20 and 9 percent believed patients would take AEDs for 3-6 months and only for episodes, respectively. About 57% of the teachers thought epileptics needed AEDs for 2-5 years. Most (77-79%) respondents thought epileptics were prohibited from using machinery or driving, and 63% thought alcohol would be prohibited. Almost two-thirds of the teachers (64%) thought they should try to place an object between the teeth of a person having an episode in order to prevent a biting injury to the tongue and 27% would restrain the person and perform chest compressions (CPR). The average total score for correct answers on the questionnaire was about 60% (29.26/50). Respondents generally understood that epilepsy is controllable (82%) and were able to identify a seizure (78.4%). The lowest scores were found in the section on identifying the types of seizures (37.8%). CONCLUSION: Teachers' knowledge of epilepsy was incomplete; thus, an epilepsy education campaign is needed and should emphasize the types of seizures, the causes of epilepsy, and management.
