Filter by:The PSK study is preliminary to the study of drug metabolism in space flight conditions. The investigators propose to use simplified blood sampling methods that can be applied in microgravity. This method is based on the use of capillary blood, obtained using an automatic lancet for diabetics, the blood droplet then being deposited on specific blotting paper, and then studied in the laboratory. In 2022, the investigators validated the transfer of artificial blood in parabolic flight conditions, as well as the validity of cardiovascular drug dosage. The objective of the 2023 study is to validate the collection and transfer of capillary blood, on themselves, by healthy volunteers with little training, for the blood dosage of caffeine after intake of standard doses of alimentary caffeine. The primary objective is a feasibility of 90% of sampling in microgravity, compared with 95% on ground. Secondary objectives are the pharmacokinetic of different forms of caffeine, according to genetic background and other modifiers of CYP1A2.
Proof of concept: Pilot Study A Pilot, proof of concept, observational study with a long-term goal to develop a minimally invasive wearable Remote Medication Monitor (RMM) that provides continuous, real-time data on methadone levels in interstitial fluid (ISF). An RMM could be used as a medication adherence monitor and would allow for the physician, counselor, patient, or family member to remotely verify that a physician-prescribed dose has been taken.
Tacrolimus (TAC) is characterized by a narrow therapeutic window, as well as high inter- and intra-individual variability in pharmacokinetics. Both under- and overexposure may lead to severe adverse effects. Therapeutic drug monitoring (TDM) is an essential element of post-transplant patient care. Most transplantation centers use C0 to adjust TAC dosage. Some controversies remain about relationship between C0 and clinical outcome. It is generally accepted that only protein-unbound drug molecules can cross cellular membranes, which imply that TDM of free tacrolimus fraction may be of paramount importance and improve clinical management of organ recipients. Whole blood TAC concentrations and dose requirements are strongly associated with CYP3A5 polymorphism. Routine CYP3A5 genotyping on the waiting lists might be useful to guide tacrolimus dosing. This interdisciplinary project tackles the research problem from three angles - biochemistry, genetics and clinical observation. The primary goal of the study is to evaluate clinical usefulness of different TDM protocols in patients after kidney and liver transplantation.
The purpose of this study is to determine the proportion of children presenting to a pediatric emergency department with an acute mental health/behavioral crisis or clinical drug toxicity who have a "match" or "mismatch" between the genes for drug metabolizing enzymes and their current or recent drug therapy. The investigators will utilize a readily available and FDA-approved cheek swab DNA test --GeneSight®--in these children that categorizes patients into 3 different type of groups - RED, YELLOW, and GREEN based on individuals' abilities to metabolize psychotropic drugs . Specific objectives include: - The relationship of genomic mismatch to serum drug concentrations, either low or high - The proportion of children with a genomic mismatch who present to PED with intentional self-injury. - The relationship between match versus mismatch and self- and caregiver-reported outcomes of functioning, drug efficacy, and drug tolerability. - Examine the proportion of children/adolescents who present to PED with an adverse drug reaction to one or more psychotropic with a genomic mismatch. - Quantify the specific adverse reactions related to a mismatch of genotypes.
