Insights

Acute kidney injury (AKI) is a growing concern. Targeting inflammation with adenosine 2A receptor (A(2A)R) agonists like ATL146e shows promise for new AKI treatments.

Area of Science:

  • Nephrology
  • Immunology
  • Pharmacology

Background:

  • Acute kidney injury (AKI) presents significant morbidity and mortality, with increasing incidence.
  • Current clinical trials for AKI have limited success, highlighting the need for better understanding of its pathogenesis.
  • Inflammation is recognized as an early event in AKI pathogenesis, making it a potential therapeutic target.

Purpose of the Study:

  • To review recent advancements in understanding inflammation's role in AKI.
  • To explore therapeutic strategies targeting inflammation via adenosine 2A receptors (A(2A)Rs).

Main Methods:

  • Review of current literature on AKI pathogenesis and inflammation.
  • Focus on compounds stimulating adenosine 2A receptors (A(2A)Rs) for anti-inflammatory effects.
  • Examination of the A(2A)R agonist ATL146e, currently in Phase III clinical trials.

Main Results:

  • Adenosine 2A receptors (A(2A)Rs) broadly inactivate inflammatory cascades.
  • ATL146e, an A(2A)R agonist, is being evaluated in Phase III clinical trials for cardiac perfusion imaging.
  • Preclinical data supports the potential of ATL146e in AKI treatment.

Conclusions:

  • Targeting inflammation through A(2A)R stimulation is a promising therapeutic avenue for AKI.
  • ATL146e's ongoing clinical evaluation may pave the way for its use in human AKI trials.

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Acute Kidney Injury II: Pathophysiology

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...
Acute Kidney Injury I: Introduction01:22

Acute Kidney Injury I: Introduction

Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...
Heart Failure Drugs: Inhibitors of Renin-Angiotensin System01:26

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...
Antihypertensive Drugs: Direct Renin Inhibitors01:25

Antihypertensive Drugs: Direct Renin Inhibitors

The renin-angiotensin-aldosterone system (RAAS) is an intricate physiological pathway involving numerous enzymes and hormones, including renin, angiotensin-converting enzyme (ACE), angiotensin I and II, and aldosterone. Imbalances within this system increase the production of angiotensin II and aldosterone. Increased angiotensin II levels promote vasoconstriction and blood pressure elevation. Concurrently, higher aldosterone levels stimulate sodium and water reabsorption in the kidneys,...
