Measurement of Cumulative Drug Exposure from Clinical Data Warehouse.

Polypharmacy (PP) and hyperpolypharmacy (HPP), are prevalent among cancer patients and are associated with an increased risk of drug-drug interactions (DDI) and potentially inappropriate medications (PIM). This study aimed to characterize PP, HPP, DDI, and PIM in patients with hematological malignancies hospitalized for hematopoietic stem cell transplantation (HSCT) by introducing a novel metric: cumulative drug exposure. Clinical data warehouse (CDW) records were employed to develop algorithms that quantified patients' cumulative exposure to these prescribing determinants during hospitalization.

Systematic review of mobile health applications in transplant patients.

Context: Poor medication management can lead to adverse outcomes for transplant patients, including acute rejection and graft loss. In recent years, mobile applications have been proposed as innovative tools to improve patient treatment management.

Objective: This review aimed to systematically evaluate the available research evidence on the relationship between mobile applications and treatment management in transplant patients.

Study of therapeutic patient education practices in French renal transplantation centres.

Objectives: Therapeutic patient education (TPE) plays a critical role in the management of kidney transplant recipients. However, discrepancies exist in the guidance provided regarding the usage of immunosuppressants across different kidney transplant centres in France.

Methods: To assess the current landscape of TPE practices in this patient population, an online questionnaire consisting of 51 questions was distributed to 32 French renal transplantation centres.

Bisphenol A and chlorinated derivatives of bisphenol A assessment in end stage renal disease patients: Impact of dialysis therapy.

Patients with end stage kidney disease treated by dialysis (ESKDD) process dialysis sessions to remove molecules usually excreted by kidneys. However, dialysis therapy could also contribute to endocrine disruptors (ED) burden. Indeed, materials like dialyzer filters, ultrapure dialysate and replacement fluid could exposed ESKDD patients to Bisphenol A (BPA) and chlorinated derivatives of BPA (ClxBPAs).

Spice-drug interactions: a case report on the use of turmeric, curry and ginger in a renal transplant patient on tacrolimus.

Tacrolimus is a widely used immunosuppressant for the prevention of rejection after transplantation. In vitro studies suggest that interactions exist between spices and tacrolimus. We present the case of a renal transplant patient aged around 70 years who was treated with prednisone, mycophenolate-mofetil and tacrolimus.

Leveraging Clinical Data Warehouses to Measure Impact of Update Prescription Guidelines of Polyvalent Immunoglobulins in 2018 in France.

In France and in other countries, we observed a significant growth in human polyvalent immunoglobulins (PvIg) usage. PvIg is manufactured from plasma collected from numeral donors, and its production is complex. Supply tensions have been observed for several years, and it is necessary to limit their consumption.

Assessing health literacy in transplant patients to better tailor the content of their therapeutic education: an observational study.

Objectives: Evaluate health literacy in transplant patients to better tailor the content of their continuing therapeutic education.

Methods: A 20-item questionnaire divided into five themes (sport/recreation, dietary measures, hygiene measures, recognition of the signs of graft rejection and medication management) was sent to transplant patient associations. Participants' responses (a score out of 20 points), were analysed according to demographic characteristics, transplanted organ (kidney, liver or heart), type of donor (living or deceased), participation in a therapeutic patient education (TPE) programme, management of end-stage renal disease (with or without dialysis) and the date of transplant.

A pharmacist-led intervention to improve kidney transplant recipient outcomes and identify patients at risk of highly variable trough tacrolimus levels: a cohort study.

Objectives: Given the positive impact of appropriate medication management on graft outcome and therefore of patient survival and graft function, the pharmacist's role in the kidney transplantation team has evolved over recent decades. The primary objective of this study was to determine whether pharmacist-led intervention after kidney transplantation is associated with a lower graft rejection rate and intra-patient variation in tacrolimus trough concentrations (C). The study's secondary objective was to develop a questionnaire to identify patients at risk for highly variable C.

Long-term lithium therapy and risk of chronic kidney disease, hyperparathyroidism and hypercalcemia: a cohort study.

Background: Lithium is well recognized as the first-line maintenance treatment for bipolar disorder (BD). However, besides therapeutic benefits attributed to lithium therapy, the associated side effects including endocrinological and renal disorders constitute important parameters in prescribing patterns and patient adherence. The objectives of this study is to (i) determine whether long-term lithium therapy is associated with a decrease in renal function, hyperparathyroidism and hypercalcemia and (ii) identify risk factors for lithium-induced chronic kidney disease (CKD).

Involvement of Transporters in Intestinal Drug-Drug Interactions of Oral Targeted Anticancer Drugs Assessed by Changes in Drug Absorption Time.

(1) Background: Oral targeted anticancer drugs are victims of presystemic pharmacokinetic drug−drug interactions (DDI). Identification of the nature of these DDIs, i.e.

Hepatotropic Peptides Grafted onto Maleimide-Decorated Nanoparticles: Preparation, Characterization and Uptake by Human HepaRG Hepatoma Cells.

We recently demonstrated the strong tropism of George Baker (GB) Virus A (GBVA10-9) and protein (CPB) derived synthetic peptides towards hepatoma cells. In a first approach, these peptides were covalently bound to poly(benzyl malate) (PMLABe) and poly(ethylene glycol)--PMLABe (PEG--PMLABe) (co)polymers, and corresponding peptide-decorated nanoparticles (NPs) were prepared by nanoprecipitation. We showed that peptide enhanced NPs internalization by hepatoma cells.

Circumsporozoite Protein of - and George Baker Virus A-Derived Peptides Trigger Efficient Cell Internalization of Bioconjugates and Functionalized Poly(ethylene glycol)--poly(benzyl malate)-Based Nanoparticles in Human Hepatoma Cells.

In order to identify the peptides, selected from the literature, that exhibit the strongest tropism towards human hepatoma cells, cell uptake assays were performed using biotinylated synthetic peptides bound to fluorescent streptavidin or engrafted onto nanoparticles (NPs), prepared from biotin-poly(ethylene glycol)--poly(benzyl malate) (Biot-PEG--PMLABe) via streptavidin bridging. Two peptides, derived from the circumsporozoite protein of - (CPB) and George Baker (GB) Virus A (GBVA10-9), strongly enhanced the endocytosis of both streptavidin conjugates and NPs in hepatoma cells, compared to primary human hepatocytes and non-hepatic cells. Unexpectedly, the uptake of CPB- and GBVA10-9 functionalized PEG--PMLABe-based NPs by hepatoma cells involved, at least in part, the peptide binding to apolipoproteins, which would promote NP's interactions with cell membrane receptors of HDL particles.

Association of Amlodipine with the Risk of In-Hospital Death in Patients with COVID-19 and Hypertension: A Reanalysis on 184 COVID-19 Patients with Hypertension.

Association between calcium channel blockers (CCBs) or functional inhibitors of acid sphingomyelinase (FIASMAs) use and decreased mortality in people with COVID-19 has been reported in recent studies. Since amlodipine is both a CCB and a FIASMA, the aim of this study was to investigate the association between chronic amlodipine use and the survival of people with hypertension infected with COVID-19. This retrospective cohort study used data extracted from the medical records of adult inpatients with hypertension and laboratory-confirmed COVID-19 between 1 March 2020 and 31 August 2020 with definite outcomes (discharged from hospital or deceased) from Erasme Hospital (Brussels, Belgium).

Difficulty in Repurposing Selective Serotonin Reuptake Inhibitors and Other Antidepressants with Functional Inhibition of Acid Sphingomyelinase in COVID-19 Infection.

The rapid spread of COVID-19 has become a health emergency causing an urgent need for drug treatments to control the outbreak, especially in more vulnerable individuals. This is reinforced by the fact that prophylactic vaccines and neutralizing monoclonal antibodies may not be fully effective against emerging variants. Despite all efforts made by the scientific community, efficient therapeutic options currently remain scarce, either in the initial, as well as in the advanced forms of the disease.

Molecular Networking for Drug Toxicities Studies: The Case of Hydroxychloroquine in COVID-19 Patients.

Using drugs to treat COVID-19 symptoms may induce adverse effects and modify patient outcomes. These adverse events may be further aggravated in obese patients, who often present different illnesses such as metabolic-associated fatty liver disease. In Rennes University Hospital, several drug such as hydroxychloroquine (HCQ) have been used in the clinical trial HARMONICOV to treat COVID-19 patients, including obese patients.

Leveraging National Claims and Hospital Big Data: Cohort Study on a Statin-Drug Interaction Use Case.

Background: Linking different sources of medical data is a promising approach to analyze care trajectories. The aim of the INSHARE (Integrating and Sharing Health Big Data for Research) project was to provide the blueprint for a technological platform that facilitates integration, sharing, and reuse of data from 2 sources: the clinical data warehouse (CDW) of the Rennes academic hospital, called eHOP (entrepôt Hôpital), and a data set extracted from the French national claim data warehouse (Système National des Données de Santé [SNDS]).

Objective: This study aims to demonstrate how the INSHARE platform can support big data analytic tasks in the health field using a pharmacovigilance use case based on statin consumption and statin-drug interactions.

Update on Functional Inhibitors of Acid Sphingomyelinase (FIASMAs) in SARS-CoV-2 Infection.

The SARS-CoV-2 outbreak is characterized by the need of the search for curative drugs for treatment. In this paper, we present an the interest of the functional inhibitors of acid sphingomyelinase (FIASMAs) in SARS-CoV-2 infection. Forty-nine FIASMAs have been suggested in the treatment of SARS-CoV-2 infection using in silico, in vitro or in vivo studies.

Unexpected overdose of oral cyclosporine in a kidney transplant patient: a case report.

Cyclosporine is a widely used immunosuppressive agent to prevent rejection of solid organ transplant. Here, we describe the case of a 71-year-old man who received the prescribed dose of cyclosporine 10 times 6 days after a kidney transplantation because of a concentration miscalculation involving two galenic forms. The patient presented gastrointestinal and neurological disorders.

Synthesis of Poly(Malic Acid) Derivatives End-Functionalized with Peptides and Preparation of Biocompatible Nanoparticles to Target Hepatoma Cells.

Recently, short synthetic peptides have gained interest as targeting agents in the design of site-specific nanomedicines. In this context, our work aimed at developing new tools for the diagnosis and/or therapy of hepatocellular carcinoma (HCC) by grafting the hepatotropic George Baker (GB) virus A (GBVA10-9) and protein (CPB)-derived peptides to the biocompatible poly(benzyl malate), PMLABe. We successfully synthesized PMLABe derivatives end-functionalized with peptides GBVA10-9, CPB, and their corresponding scrambled peptides through a thiol/maleimide reaction.
