Filter by:The goal of this study is to compare the impact of metabolic surgery and a class of anti-diabetes medications (Glucagon-like peptide-1 receptor agonists,GLP-1 RAs) on occurrence of diseases involving small and large vessels such as heart disease, kidney disease, and disease of the retina (a part of the eye), as well as deaths.
Renal progenitors are a subset of parietal epithelial cells (PECs) localized at the urinary pole of Bowman's capsule. Experimental models of podocyte damage showed that PECs can potentially regenerate lost podocytes by migrating from Bowman's capsule to the glomerular tuft, acquiring the morphological and functional features of mature podocytes. Podocyte loss and damage, as well as the inability of PECs to replace lost podocytes, lead to glomerular scarring and chronic kidney disease (CKD) progression. In addition, the investigators of the present study and others have recently demonstrated the existence of a specific subpopulation of tubular cells in the human kidney with a high potential for regeneration and resistance to death, thus acting as tubular progenitors. These cells are involved in tubular response to damage during acute kidney injury (AKI) trough endoreplication (polyploidization). Kidney biopsy is the cornerstone of diagnosis in many kidney diseases leading to CKD and AKI, allowing unambiguous diagnosis in some cases and presumptive diagnosis of ongoing disease in others. Very recently, super resolution imaging techniques proved to maintain current diagnostic standards while allowing to study morphological features of pathophysiological mechanisms of glomerular and tubular diseases. The rationale of this project is to study the role of renal progenitors (PECs and tubular progenitors) in the pathogenesis of CKD and AKI trough super resolution imaging applied to human renal biopsies, to the aim of identifying relevant connections with clinical data and markers of damage and/or disease progression.
The primary purpose of this study is to evaluate the effect of mitapivat on albumin creatinine ratio (ACR) response in participants with sickle cell disease (SCD) and nephropathy.
Background: Sodium-glucose-cotransporter (SGLT) inhibition has been observed to reduce risk of cardiovascular events and kidney failure in persons with type 2 diabetes. People with type 1 diabetes also have increased risk of cardiovascular and kidney disease, and may benefit from SGLT-inhibition. The exact mechanism of how SGLT-inhibition benefits the kidneys are yet unknown. Change in renal hypoxia may be a factor. Objective: The primary aim of this study is to assess the effects of 12 weeks SGLT-1 and 2 inhibition on renal oxygenation in persons with type 1 diabetes and chronic kidney disease. Further aims are to study if renal oxygen consumption and response to SGLT-inhibition differs between people of African-Caribbean or Northern European decent. Additionally effects on left ventricular ejection fraction, kidney function and biomarkers in blood and urine will be explored. Method: 12 weeks treatment with oral sotagliflozin or matching placebo as intervention. Kidney oxygenation and perfusion parameters and left ventricular ejection fraction will be assessed by functional magnetic resonance imaging. Kidney function and biomarkers will be assessed according to local hospital laboratory guidelines. Design: Randomized, double-blinded, placebo-controlled, cross over intervention study. Study population: 69 persons with type 1 diabetes and diabetic kidney disease with albuminuria will be included, 39 at Steno Diabetes Center Copenhagen, 30 at King's College London. Endpoints: Primary end-point: Change from 0 to 12 weeks in dynamic R2*-weighted signal after treatment with sotagliflozin compared to placebo. Secondary endpoints: Change from 0 to 12 weeks with sotagliflozin compared with placebo on renal perfusion, renal artery flow, renal oxygen consumption, renal parenchymal triglyceride fraction, renal fibrosis, left ventricular ejection fraction, urinary albumin-creatinin ratio, ketone bodies, erythropoietin, pro brain natriuretic peptide, and plasma- and urine inflammation- and fibrosis biomarkers as well as difference after 12 weeks treatment in glomerular filtration rate. Timeframe: Inclusion of patients from february 2024. Last visit september 2025. Presentation spring 2026, publication fall 2026.
The goal of this real-world observational study is to evaluate the effectiveness and safety of the Chinese herbal-derived therapeutic Danshen injection following immunosuppressive therapy and prophylactic anticoagulation with low molecular heparin for acute kidney injury in primary nephrotic syndrome. The main questions to answer are: Whether or not Danshen injection is beneficial for acute kidney injury patients in primary nephrotic syndrome patients. Whether or not Danshen injection will increase the bleeding risk in primary nephrotic syndrome patients receiving low molecular heparin. Participants' information will be retrieved from hospital files stored in medical records and the electronic patient data registry. Participants received Danshen injection will be compared with control group to evaluate the recovery of renal function and side effects.
<Development of synthetic medical data generation technology to predict postoperative complications> In order to develop a model for predicting the occurrence of complications after surgery, it is necessary to establish a cohort along with statistical indicators related to the occurrence of complications. This study aims to combine synthetic medical data based on actual clinical data and develop a predictive model based on synthetic medical data. This will allow researchers to conduct research only with synthetic data without dealing with actual medical data, allowing them to use and process data without legal constraints, and to create as much data as they want based on various preprocessed, standardized, and labeled raw data. Patients from three hospitals in Korea (Seoul National University Hospital, Seoul National University Bundang Hospital, Seoul Metropolitan City-Boramae Medical Center) were enrolled for the study. Medical data (both clinical and laboratory) from 410,000 patients who were conducted surgery between 2005 and 2020 were collected to evaluate the performance of the prediction model using AKI-based prediction model development and external verification. Based on the collected patient data, synthetic medical data were combined using the machine learning algorithm, and the anonymity and re-identification of the synthesized medical data were evaluated. Also, the development of AI-based prediction model using synthetic medical data and the actual medical data model were compared.

Lung cancer is the leading cause of death worldwide, with non-small-cell lung cancer (NSCLC) being the most common histotype according to the global cancer observatory 2022. A variety of therapeutic options for advanced/metastatic non-oncogene-addicted NSCLC have recently been approved based on their impact on patient outcomes in terms of survival and safety profile. Current guidelines advocate for personalized treatment options based on molecular and immunologic characteristics, which drives the physician's decision toward tailored oncology. In the last two to three decades, hundreds of cancer biological prognostic markers for non-small cell lung cancer have been proposed. Although they have shown a potential in this field, validation studies are still required and, to date, there is in sufficient evidence to recommend the routine clinical use of any of these putative biomarkers. Therefore, the discovery of robust prognostic and/or predictive biomarkers in patients with non-small cell lung cancer is imperative for advancing treatment strategies for the disease and improving patient care.
Recent breakthroughs in medical genetics have discovered that a portion of kidney failure affecting the Black community is mediated by coding variants in a gene called apolipoprotein L1 (APOL1) - and that genetic variants, not race - account for increased risk. For APOL1 genetic testing to be applied in a manner that improves patient care and outcomes, more information is needed regarding associations of genotype with clinical parameters related to kidney health. Further, understanding patient perceptions about knowledge of the results of APOL1 genetic testing, and how that impacts patient engagement with management of hypertension and other renal risk factors, is urgently needed. - In a Phase 1 pilot study, we offered APOL1 genetic testing to Black patients seen in our Hypertension and Nephrology clinics at Saint Louis University, an academic medical center that serves the local urban community, and surveyed patients on attitudes and concerns about APOL1 genetic testing. 144 participants were enrolled in Phase 1. - In the Phase 2 study, we will advance this important work in our community by offering participation to a broader patient base, including patients seen in Internal and Family Medicine clinics, SLU Hospital, as well as to first-degree relatives and spouses of SLUCare participants. This expansion seeks to advance understanding of environment-gene interactions, improve risk prediction, and target management of potentially modifiable risk factors.
The current protocol plans to enroll participants with youth-onset Type 2 Diabetes (T2D) as well as obese and lean controls from the Renal-HEIR - Renal Hemodynamics, Energetics and Insulin Resistance in Youth Onset Type 2 Diabetes Study (n=100) [COMIRB #16-1752] in a prospective investigation that seeks to 1) define the changes in kidney function by gold standard techniques and energetics by functional Magnetic Resonance Imaging (MRI) in adolescents with and without T2D as they transition to young adulthood; 2) quantify kidney oxidative metabolism by 11C-acetate Positron Emission Tomography (PET) in a subset of participants who are ≥18 years of age with youth-onset T2D and/or obesity; 3) determine peripheral arterial stiffness by SphygmoCor. Mechanistic insight will be provided by transcriptomic analyses of repeat biopsies 3-years after their initial biopsy for eligible participants with youth-onset T2D, as well as molecular analysis of tissue obtained from J-wire endovascular biopsies. This study will also leverage this well-characterized cohort of youths to define youth-onset T2D-related changes in brain morphology and function by structural MRI and resting-state functional MRI and through the assessment of cognitive function (fluid and crystallized intelligence) using the NIH Toolbox Cognitive Battery (NIHTB-CB), as an exploratory objective. All enrollees in Renal-HEIR have consented to be contacted for future research opportunities.
