Acute kidney injury

Area of Science:

• Nephrology
• Critical Care Medicine
• Regenerative Medicine

Background:

• Acute kidney injury (AKI) is a common and severe complication in hospitalized patients, with persistent high mortality rates over two decades.
• AKI often stems from transient renal hypoperfusion or ischemia, leading to tubular damage, inflammation, and microvasculopathy, which perpetuate kidney injury.
• Clinical effects include impaired excretion of fluids, electrolytes, and waste products, alongside risks of cardiovascular complications and uremia.

Purpose of the Study:

• To review the current understanding of acute kidney injury (AKI) pathophysiology, diagnosis, and treatment.
• To highlight the limitations of current therapeutic strategies and the urgent need for novel treatments.
• To explore the potential of stem cell-based therapies for improving AKI outcomes.

Main Methods:

• Review of existing literature on acute kidney injury (AKI).
• Analysis of diagnostic approaches, including the role of renal biopsy.
• Evaluation of current treatment strategies and their efficacy.
• Exploration of emerging therapeutic avenues, particularly stem cell therapies.

Main Results:

• Current therapies for AKI primarily focus on preventing further damage and managing complications, with limited success in improving prognosis.
• Pharmacological interventions have largely failed to demonstrate significant benefits.
• Renal replacement therapies, including intermittent and continuous methods, are equally effective when dialysis is required.

Conclusions:

• There is an urgent need for innovative therapies to improve both short- and long-term outcomes in acute kidney injury (AKI).
• Stem cell-based regimens represent a promising future direction for AKI treatment.
• Further research into regenerative medicine approaches is warranted to address the unmet needs in AKI management.
