Acute toxic kidney injury

Area of Science:

• Nephrology
• Toxicology
• Internal Medicine

Background:

• The kidney's unique physiology makes it susceptible to injury from a wide array of nephrotoxic agents.
• Acute kidney injury (AKI) from toxic substances is a significant global health challenge, with varied epidemiology.
• Understanding the diverse sources and mechanisms of nephrotoxicity is crucial for effective management.

Purpose of the Study:

• To review the spectrum of nephrotoxic insults encountered in clinical practice.
• To consolidate information on diverse nephrotoxic agents, including medications, natural toxins, and environmental chemicals.
• To provide an overview of the diagnosis, clinical presentation, and management of poisoning-induced AKI.

Main Methods:

• Comprehensive literature review focusing on nephrotoxic substances and their impact on kidney function.
• Categorization of nephrotoxic agents by source: medications, plants, animal venoms, environmental chemicals, and illicit drugs.
• Synthesis of information on pathophysiological pathways, clinical manifestations, and therapeutic interventions.

Main Results:

• A wide range of substances, including common medications, plant-derived toxins, animal venoms, agricultural chemicals, and illicit drugs, can induce AKI.
• Nephrotoxicity occurs via diverse mechanisms, often exacerbated by drug interactions and individual patient factors.
• Toxic AKI presents with varied clinical signs and often involves dysfunction of other organs.

Conclusions:

• Nephrotoxic AKI is a complex clinical problem requiring a broad understanding of potential causative agents.
• Early diagnosis and prompt management are essential for improving outcomes in patients with toxic AKI.
• Further research into the mechanisms and treatment of toxic AKI is warranted to mitigate its impact.
