Filter by:Integrity of the corneal epithelium is the function of intact limbal stem cells. The reduction in the population of LSCs and their dysfunction result in abnormal corneal epithelialization and invasion of the corneal surface by the conjunctival epithelium with or without corneal neovascularization that is, limbal stem cell deficiency (LSCD). Different techniques have been developed to treat cases of limbal stem cell deficiency due to traumatic or congenital cases. Recent innovations developed to predict the early stages of stem cell deficiency. One of these methods is measurement of the central epithelial thickness as it was found that limbal stem cell deficiency causes reduction of the central epithelial thickness. The aim of this study is to study changes in the corneal epithelial thickness at different quadrants of the cornea to observe the exact time of epithelial stability following stem cell transplantation.
Numerous publications call for innovation based on integrated care principles, investment in self-management and use of eHealth to improve outcomes for allogeneic Stem Cell Transplant (alloSCT). While eHealth supported integrated care models are effective, real-world implementation remain elusive. The newly developed SMILe-Integrated Care Model (ICM) is the first theory-based eHealth supported integrated care model for alloSCT patients. SMILe-ICM includes four self-management modules (i.e., monitoring & follow-up, medication adherence, infection prevention, physical activity) and combines a human role, i.e., a Care Coordinator (CC), with a technological component (i.e., the SMILeApp). Patients monitor and transfer symptoms and health behaviours to their CC, who supports them in self-management and dealing with complications. Embedded in implementation science methodology, we aim to implement and test the SMILe-ICM at the University Hospital Basel (USB) in the first year post-alloSCT by evaluating effectiveness, implementation outcomes and implementation pathway. A hybrid 1 effectiveness-implementation randomized controlled trial will include 80 adult alloSCT patients who are transplanted and followed up at USB, have basic German proficiency and provide written informed consent. Patients with physical or mental conditions limiting the use of the SMILeApp will be excluded. About ten days before alloSCT, a stratified randomization based on participants' clinical risk scores will assign patients 1:1 to the control (CG) or intervention group (IG). The CG will receive usual care; the IG will receive the SMILe-ICM over one year with 12 CC visits and continuous use of the SMILeApp. Re-hospitalization rate (primary outcome), total healthcare utilization costs, acute and chronic GvHD episodes and survival will be assessed using medical records. Medication adherence will be assessed via the BAASIS© scale, treatment burden via the PETS©, health-related quality of life via the EQ-5D-5L©. Implementation outcomes will be assessed via questionnaires and the implementation pathway via qualitative focus groups, each from patient and CC perspectives. Patients will be followed up 3 months after the intervention ended. Intention-to-treat and per-protocol analyses will be conducted using the rate ratio by unconditional maximum likelihood estimation (Wald) for the primary outcome. Qualitative data will be analysed using mind-mapping techniques and thematic analysis.
This study is a Phase 2 multicenter study with a Safety Lead-in evaluating safety and efficacy of MT-401 administration to patients with AML, who have received their first allogeneic HSCT. The dose administered is 50 x 10^6 cells (flat dosing).
Introduction. Chronic graft-versus-host-disease (GVHD) is the main late noninfectious complication after allogeneic hematopoietic stem cell transplantation (HSCT) that can affect several organs. Bronchiolitis obliterans syndrome (BOS) is recognized as pulmonary chronic GVHD. A diagnosis of a lower respiratory tract infection in the first 100 days following transplant has been associated to the development of BOS. One hypothesis is that the first stage driving to BOS is a previous aggression of bronchial epithelial cells by various factors such as chemotherapy and radiotherapy. Thereafter, data suggest that viral infections, in particular Parainfluenza viruses could be a trigger for BOS. The alloimmune reaction activated by the respiratory virus could lead to the fibrosis process. Our hypothesis is that the bronchial epithelium of allogeneic HSCT recipients has phenotypic specificities that are associated with a specific response to the viral respiratory infections (in particular paramyxovirus) leading to the development of BOS. Main objective. To characterize and compare the inflammatory response after infection with Parainfluenza 3 virus in an ex-vivo model of bronchial epithelial cells obtained from allogeneic HSCT recipients and controls. Objective secondary. To characterize the phenotypic specificities of allogeneic HSCT recipients' bronchial epithelium. Methodology, and experimental plan. Prospective, monocentric research. Bronchial biopsies obtained from patients, will be completely differentiated after 21 days of culture. Epithelial cells will be infected by the virus strain Parainfluenza 3. Transcriptome of the cells from both allogeneic HSCT patients and controls, infected and non-infected will be analyzed 48 hours after infection.
