Filter by:This study aims to investigate the effect of EBV reactivation or EBV reactivation added with dexamethasone(DXM) in patients with adverse drug reactions(CDR) , through evaluating the levels on monocyte, macrophage M2/M1 and cytokines. To investigate whether expression of EBV receptors EphA2 could specifically influence on EBV activation in CDRs. We performed a prospective longitudinal study on the frequencies of Monocyte, Macrophage, M2/M1 and cytokines included IL-4,IL-13,TNF-α,IFN-γ,IFN-β, CXCL9 and CXCL10 after onset of MPE ,SJS/TEN and control groups. PBMCs collected from peripheral blood were cocultured with EBV or EBV with DXM. We next examined whether EBV or EBV with DXM could have a strong impact on the MOs, Mac, M2/M1 and cytokines and which cytokines could be crucial for the interaction between M2/M1 and EBV, by in vitro cocultures. Finally, EphA2 were detected to evaluate reactivation of EBV.
Voriconazole is a drug used to treat invasive fungal infections. The amount of voriconazole in a person's blood helps to determine how effectively it treats an infection, and how safe it is. Patients respond differently when receiving the same dose - some clearly benefit, other patients experience side effects, and others see limited improvement in their infection. Voriconazole is broken down in the liver mainly by an enzyme called CYP2C19, before being excreted from the body. The activity of CY2C19 differs between people because of variation in the DNA that encodes the body's instructions to make CYP2C19. If CYP2C19 activity is very high, voriconazole blood levels may remain below the target range when a patient receives a standard dose of voriconazole, which may be insufficient to treat their infection. Besides, children tend to have faster voriconazole metabolism regardless of the genetic makeup, mainly because of higher liver mass/body proportion. That's why, younger patients needs higher doses and it is harder for them to reach target range. Having a high CYP2C19 activity and being young combined may cause to consider choosing an alternative drug. By contrast, decreased CYP2C19 activity due to genetic variation may result in excessively high voriconazole blood levels, predisposing to serious side effects. Therefore, knowing a patient's CYP2C19 genetic makeup is very important for predicting their response to voriconazole. Thus, we aim to determine the influence of genetic variation in CYP2C19 on the frequency and severity of side effects related to voriconazole, and on the effectiveness of voriconazole for treating serious fungal infections. The findings from this study will contribute to determining the optimal dose of voriconazole that patients with different genetic variants in CYP2C19 should be started on, and will take us one step closer to both understanding the genetic structure of CYP2C19 in the Turkish population, and to 'personalised medicine'.

Ofloxacin is a gold standard antibiotic for the treatment of bone and joint infections due to sensible staphylococcus strains. However, in the elderly, inter-individual variability of the pharmacokinetics may reduce the efficacy or increase toxicity. The occurrence of ofloxacin side effects is likely to be increased in case of higher exposition. However, the serum concentration-toxicity relationship has not yet been determined. The purpose of this project is to assess the association between the residual serum concentration of ofloxacin at day 3 and the occurrence of at least one adverse effect attributable to ofloxacin, and determine a threshold toxicity concentration if this association exists.
This registry aims to monitor the safety of Qizhi Tongluo Capsules and to identify the potential risk factors for its adverse drug reactions.
CAR-T cells and cellular therapies may lead to various adverse reactions. This study investigates reports of different toxicities for cellular therapies in the World Health Organization's (WHO) global database of individual safety case reports (VigiBase).
Adverse drug reactions are an important public health consern that affects physician prescriptions and practice. The responsibilities of healthcare professionals in monitoring, prevention, treatment and reporting of drug hypersensitivity reactions and drug allergies are essential for patient safety. Providing drug safety must be one of the main goals to be achieved for every member of our society. In our study, we planned to evaluate the knowledge, attitudes, and behaviors of healthcare workers in our country about drug hypersensitivity reactions in pediatric patients and to determine the risk factors that may affect them.
This registry aims to monitor the safety of Xueshuantong Injection and to identify the potential risk factors for the adverse drug reactions.
Patients meeting eligibility criteria will be randomized into two groups, one receiving pharmacogenetic testing and the other not receiving pharmacogenetic testing. In this open-label trial, a pharmacist will make medication therapy recommendations using YouScript® Personalized Prescribing System for patients who receive genetic testing and standard drug information resources per usual for patients who do not undergo pharmacogenetic testing.
This registry aims to monitor the safety of Compound Kuh-seng Injection and to identify the potential risk factors for the adverse drug reactions. Compound Kuh-seng Injection is a kind of natural compound injection extracted from herbs Kuh-seng (Radix Sophorae Flavescentis) and Rhizoma Heterosmilacis Japonicae.
