RESUMO
BackgroundEpilepsy is a common and devastating neurological disease. Its treatment, especially when using phenobarbital, causes liver complications, and it is therefore essential to identify a way to reduce liver complications. This study aimed to investigate the protective effect of ursodeoxycholic acid on liver function in pediatric patients with seizure treated with phenobarbital. Materials and methods:Materials and methods: The present study was conducted on 80 patients (40 in the placebo group and 40 in the ursodeoxycholic acid group). To assess the effect of intervention, liver enzyme levels after five weeks of treatment were recorded. Independent t-test and ANOVA repeated measures were used to compare the means. Conclusions:The study results showed that the administration of ursodeoxycholic acid had a relative effect in improving liver function in patients with liver injury caused by phenobarbital.
RESUMO
INTRODUCTION: Metastatic or recurrent colorectal cancer (MRCRC) has a poor prognosis. The aim of the present meta-analysis was to assess the prevalence of different subtypes of KRAS mutation and BRAF mutation in metastatic CRC patients, and evaluate the relationship between the tumor sidedness and prevalence of KRAS and BRAF mutation. METHODS: We searched MEDLINE/PubMed, the Cochrane Library, and ClinicalTrials.gov from January 2010 to July 2020. The data were extracted independently according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The statistical analysis was done using STATA and Meta-Disk 1.4 applications. RESULTS: Overall, 6699 colorectal cancer patients were included. KRAS and BRAF mutation was reported in 28% and 6% of patients, respectively. The overall prevalence of right primary and left primary metastatic CRC patients with mutated KRAS was 40% and 60%. However, the prevalence BRAF mutated right primary and left primary metastatic CRC patients was 37% and 63%. The overall HR was 2.38 for patients with metastatic CRC who had a mutated type of KRAS. Our study showed a mean overall survival of 35.4 month for KRAS mutant and a 10.12 month survival for BRAF mutant patients with metastatic colorectal cancer patients. CONCLUSION: The prevalence of KRAS and BRAF mutations varied significantly according to the location of the tumor. BRAF mutations are more commonly found in metastatic colorectal cancers on the right side. Liver was the most common site of metastases in patients with mutant KRAS and the mortality of patients with mutant KRAS was 2.3 times higher than the patients with wild types. These results help to better describe the population of mCRC patients and can have implications for improving and organizing anti-EGFR therapies. Further research is needed to assess differences in survival through mutation status and primary tumor location.
