AI Article Synopsis

  • * Sixty CCHF patients were studied, showing significantly higher levels of ET-1, Ang-2, and Tie-2 compared to a control group, indicating a biological response to the severe illness.
  • * The findings suggest that elevated ET-1 and Tie-2 levels are linked to more severe outcomes in CCHF, while Ang-2 levels inversely correlate with disease severity, highlighting their potential as prognostic markers for treatment

Article Abstract

Background/aim: Crimean-Congo hemorrhagic fever (CCHF) is a serious illness characterized by fever and hemorrhage. Endothelin-1 (ET-1), angiopoietin-2 (Ang-2), and endothelial cell-specific receptor tyrosine kinase (Tie-2) are believed to be important markers of the pathogenesis, clinical course, and prognosis of the disease. The aim of this study was to determine ET-1, Ang-2, and Tie-2 levels in adults with CCHF and investigate the associations between these markers and pathogenesis and disease course.

Materials And Methods: Sixty CCHF patients were included in the study. The patients were classified according to disease severity criteria and Ang-2, Tie-2, and ET-1 levels were compared.

Results: Mean serum ET-1 level was 36.62 ± 27.99 pg/mL in the patient group and 3.70 ± 4.71 pg/mL in the control group (P = 0.001). Mean serum Ang-2 levels were 2511.18 ± 1018.64 pg/mL in the patient group and 3570.76 ± 209.52 pg/mL in the control group (P = 0.001). Mean serum Tie-2 levels were 7.35 ± 7.75 ng/mL in the patient group and 0.67 ± 1.26 ng/mL in the control group (P = 0.001).

Conclusion: Elevated ET-1 and Tie-2 levels were associated with more severe disease course, while Ang-2 level was negatively correlated with severity in adult CCHF patients. ET-1, Tie-2, and Ang-2 levels are important prognostic parameters in CCHF and may contribute significantly to treatment and follow-up.

Circulating biomarkers associated with pediatric sickle cell disease.

Article Synopsis
  • Sickle cell disease (SCD) is a genetic disorder caused by a mutation in the HBB gene, resulting in abnormal hemoglobin S that deforms red blood cells, leading to severe health complications such as pain, anemia, and organ damage.
  • The disease is prevalent, especially in sub-Saharan Africa, where over 7.5 million people are affected, often facing underdiagnosis and poor management, particularly in children.
  • This study in Ghana aims to identify specific circulating biomarkers in pediatric SCD patients that could help predict disease outcomes and improve patient care by assessing various serum markers associated with inflammation and neuronal injury.

Background: The Tie2/Ang pathway was found to be involved in forming tumor blood vessels in various tumors. The goal of this study was to evaluate the value of Tie2/Ang pathway as a novel biomarkers for the early detection of chronic hepatitis C virus (CHC)-related hepatocellular carcinoma (HCC). And the possibility of their future application in HCC treatment.

Microglial cell proliferation is regulated, in part, by reactive astrocyte ETB signaling after ischemic stroke.

Reciprocal communication between reactive astrocytes and microglial cells provides local, coordinated control over critical processes such as neuroinflammation, neuroprotection, and scar formation after CNS injury, but is poorly understood. The vasoactive peptide hormone endothelin (ET) is released and/or secreted by endothelial cells, microglial cells and astrocytes early after ischemic stroke and other forms of brain injury. To better understand glial cell communication after stroke, we sought to identify paracrine effectors produced and secreted downstream of astroglial endothelin receptor B (ETB) signaling.

Exploring Angiopoietin-2: Clinical Insights and Experimental Perspectives in Kidney Diseases.

Kidney Int Rep

December 2024

Graduate Institute of Physiology, College of Medicine, National Taiwan University, Taipei, Taiwan.

Angiopoietin-2, an important contributor to angiogenesis and vascular remodeling, is increasingly recognized in kidney research. This review explores clinical insights and experimental perspectives on angiopoietin-2 in kidney diseases. Traditionally seen as an antagonist of the Tie-2, which is a receptor tyrosine kinase of endothelial cells and some hematopoietic stem cells, angiopoietin-2 exerts both proangiogenic and antiangiogenic effects, making it a versatile and context-dependent player in kidney pathophysiology.
