Filter by:Changes in the metabolic ability of cytochrome P-450 during child development can affect both bioavailability and elimination depending on the involvement of intestinal and hepatic metabolic processes. The age-related variability of cytochrome P-450 isoenzymes in children has been described since 2010. The variability in the development of the activity of specific cytochrome P-450 isoenzymes illustrates why the pharmacogenetic features of the medicine use at different age periods should be studied for individual drugs. This will provide an understanding of the mechanisms for preventing adverse events appearing in pediatric intensive care units while more common antimicrobial pharmacotherapy is administered. Improved knowledge of the pharmacogenetic characteristics of cytochrome P-450 and the unintended consequences of modulation of its isoenzymes could provide an understanding of the susceptibility to adverse events in children in critical conditions staying at Intensive Care unit (ICU).
The goal of this pilot study is to establish the feasibility and initial efficacy of the combination of phentermine and topiramate for adolescents and young adults who require additional risk reduction after bariatric surgery. This study will use a randomized, placebo-controlled, double-blinded design to evaluate an adjunctive 12-week intervention of phentermine + topiramate + standard of care vs. placebos + standard of care 6 months after bariatric surgery, among 12 to 24 year olds who don't achieve expected weight loss or who remain severely obese (n=10 total).
Closed loop technology has been shown to reduce both hypoglycemia and hyperglycemia, as well as reduce glycemic variability. Sensor augmented pump (SAP) therapy means the addition of alerts according to high or low glucose values as well as trend arrows showing actual glucose trends to pump therapy. This Hybrid closed loop (HCL) system provides several additional effects compared to SAP therapy: according to actual and predicted sensor glucose values, the insulin therapy can be adopted automatically by pump: in case of high values (or predicted) more insulin will be administered, in case of low values (or predicted) the insulin infusion will be decreased a suspended and resumed again. So the HCL provides a lot more automatic functions to keep glucose in target compared to SAP. The aim of the current trial is to compare the SAP-therapy with the hybrid closed loop glucose management in patients with type 1 diabetes at home.
Preclinical models of urogenital carcinoma have been emerging as a way to pre-determine drug resistance before therapy is targeted. The implantation of tumor specimens in the chorioallantoic membrane (CAM) of the chicken embryo results in a high-efficiency graft, thus allowing large-scale studies of "tumor avatar". The aim of the study is to develop a tumor culture platform for treatment evaluation. Biopsies will be collected from primary tumors of patients and grafted onto the chorioallantoic membrane of chicken embryos. After tumor implantation at the CAM, tumor growth will be accompanied by imaging that will quantify tumor vascularization, tumor volume, and tumor blood flow. Following tumor growth, "avatars" will be divided into different treatments. Using the "tumor avatar" model together with patient tumors, the investigators will be able to observe the individualized tumor response for each patient in a treatment context, as well as determine the potential drug to be used in each case. These results may support a phenotype-based reading within 7-10 days.
To evaluate the efficacy and safety of neoadjuvant FOLFOXIRI chemotherapy (irinotecan, oxaliplatin and fluorouracil) in the patients with resectable liver metastasis of colorectal cancer
To evaluate the efficacy and safety of totally neoadjuvant FOLFOXIRI chemotherapy (irinotecan, oxaliplatin and fluorouracil) followed by short-course radiation therapy and XELOX chemotherapy in the patients with locally advanced rectal cancer.
To evaluate the efficacy and safety of neoadjuvant FOLFOXIRI chemotherapy (irinotecan, oxaliplatin and fluorouracil) in the patients with locally advanced colon cancer.
In last few years, most researches about hepatic complication after chemotherapy focused on hepatitis B virus (HBV). With adequate prophylaxis and monitor, HBV-related hepatitis flares can be prevented. In contrast, cancer patients with hepatitis C virus (HCV) infection are traditionally considered as relative safe to receive chemotherapy. However, two large retrospective studies recently showed that severe hepatitis could develop in 14-27% lymphoma patients with chronic HCV infection, including 3-4% hepatic failure. The risk factors to predict severe hepatitis are pre-treatment elevated ALT level and liver cirrhosis. Due to the lack of prospective studies, the dynamic changes of serum HCV RNA levels and the association of hepatitis are still unclear. Some epidemiologic studies demonstrated an association between HCV infection and B-cell lymphoma. Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma and several reports showed higher prevalence of HCV infection among DLBCL patients than the controls. HCV infected DLBCL patients are reported to have distinct clinical characteristics, such as older, more with elevated LDH levels, and more with extra-nodal involvement. Regarding the impact of HCV infection on prognosis, the results are conflicting. Taiwan is an endemic area of HCV but there are limited reports addressing the clinical characteristics and prognosis in this unique population. Therefore, the investigators initiate a prospective, multi-center observational study to clarify the dynamic association between serum HCV RNA levels and hepatitis in HCV-infected lymphoma patients treated with chemotherapy.
The investigators want to research whether genetic polymorphisms of drug-metabolizing enzymes can be used to predict chemotherapeutic outcomes in patients with metastatic breast cancer.
Objective: the objective of this study in china is to clarify, whether the overall survival is different between previously untreated stage IIIB/IV lung adenocarcinoma with EGFR mutations receiving first-line erlotinib plus second-line docetaxel/cisplatin and those receiving first-line docetaxel/cisplatin plus second-line erlotinib .
