Biomarker Panels for Discriminating Risk of CKD Progression in Children.

J Am Soc Nephrol

January 2025

Department of Pediatrics, Division of Nephrology, The Children's Hospital of Philadelphia, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, PA.

Background: We have previously studied biomarkers of tubular health (EGF), injury (KIM-1), dysfunction (alpha-1 microglobulin), and inflammation (TNFR-1, TNFR-2, MCP-1, YKL-40, suPAR), and demonstrated that plasma KIM-1, TNFR-1, TNFR-2 and urine KIM-1, EGF, MCP-1, urine alpha-1 microglobulin are each independently associated with CKD progression in children. In this study, we used bootstrapped survival trees to identify a combination of biomarkers to predict CKD progression in children.

Methods: The CKiD Cohort Study prospectively enrolled children 6 months to 16 years old with an eGFR of 30-90 ml/min/1.

CRISPR-based gene therapy for the induction of fetal hemoglobin in sickle cell disease.

Expert Rev Hematol

December 2024

Department of Medicine, Division of Hematology and Medical Oncology, Center of Excellence for Sickle Cell Disease, Boston University School of Medicine and Boston Medical Center, Boston, MA, USA.

Introduction: Sickle cell disease is ameliorated and perhaps can be 'cured' if enough fetal hemoglobin is present in most erythrocytes. Hydroxyurea, which increases fetal hemoglobin levels, is widely available and effective, especially in children. Nevertheless, only cell-based gene therapy can achieve a 'curative' fetal hemoglobin threshold.

Glycolytic lactate in diabetic kidney disease.

JCI Insight

June 2024

Center for Precision Medicine, Division of Nephrology, Department of Medicine, University of Texas Health San Antonio, San Antonio, Texas, USA.

Article Synopsis
  • Lactate is a key indicator of mitochondrial dysfunction, and recent studies are exploring its significance in diabetic kidney disease (DKD), particularly in individuals with type 2 diabetes (T2D) and type 1 diabetes (T1D).
  • In cohorts of T2D patients (HUNT3, SMART2D, CRIC), higher urine lactate levels were linked to worse kidney function and faster declines in glomerular filtration rate; additionally, increased lactate levels were observed in T1D patients during glucose challenges.
  • The study suggests that elevated lactate, particularly in diabetic conditions, may inhibit important mitochondrial processes and contribute to the pathology of DKD, potentially through mechanisms
