Rhabdomyolysis: What Is It?

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Rhabdomyolysis is a serious condition that can lead to significant morbidity and mortality, primarily due to its potential to cause acute kidney injury. Understanding the underlying mechanisms and identifying effective treatment strategies are crucial for improving patient outcomes. Ongoing research continues to explore new therapeutic options to mitigate the effects of this condition and enhance recovery.

Rhabdomyolysis is a clinical syndrome characterized by the breakdown of skeletal muscle fibers, leading to the release of muscle cell contents into the bloodstream. This condition can result from various causes, including physical trauma, infections, and certain medications. The release of intracellular components, particularly myoglobin, can lead to severe complications such as acute kidney injury (AKI).

Causes of Rhabdomyolysis

Rhabdomyolysis can be triggered by multiple factors:

• Infections: Both viral and bacterial infections can induce rhabdomyolysis. Streptococcus pneumoniae and Staphylococcus aureus are common gram-positive bacteria associated with this condition, while gram-negative bacteria have also been implicated in sepsis-induced rhabdomyolysis1.
• Physical Exertion: Exertional rhabdomyolysis occurs after intense physical activity, especially activities involving strenuous eccentric exercises, such as those found in extreme conditioning programs like CrossFit®7.
• Medications and Toxins: Certain drugs and toxins can cause muscle damage leading to rhabdomyolysis. For instance, toxic rhabdomyolysis can be complicated by AKI, necessitating extracorporeal detoxification methods3.

Pathophysiology

The primary pathological event in rhabdomyolysis is the destruction of muscle cells, which releases intracellular contents such as myoglobin, creatine kinase, and electrolytes into the circulation. Myoglobin, in particular, is nephrotoxic and can cause AKI by obstructing renal tubules and inducing oxidative stress and inflammation2 4 5.

Complications

One of the most severe complications of rhabdomyolysis is acute kidney injury (AKI). The mechanisms leading to AKI include:

• Direct Toxic Effects: Myoglobin and its breakdown products can have direct toxic effects on renal tubules1.
• Renal Ischemia: The release of vasoconstrictive mediators can reduce renal blood flow, contributing to ischemia1.
• Oxidative Stress and Inflammation: Increased oxidative stress and inflammatory responses further exacerbate renal damage8 9.
