Capillary leak syndrome causes protein-rich fluid loss, leading to edema and organ failure. This review details non-sepsis causes, pathophysiology, and treatment of this critical condition.
Area of Science:
- Medicine
- Pathophysiology
- Clinical Science
Background:
- Increased capillary permeability to proteins causes fluid shifts, leading to edema and organ dysfunction.
- Sepsis is a common cause, but many other conditions manifest as a "sepsis-like" syndrome.
- Capillary leak syndrome (CLS) describes this complex of symptoms associated with heightened protein permeability.
Purpose of the Study:
- To explore diseases beyond sepsis that induce capillary leak.
- To review the shared pathophysiology of these diverse conditions.
- To discuss current treatment strategies for capillary leak syndrome.
Main Methods:
- Literature review of non-sepsis causes of capillary leak.
- Analysis of collective pathophysiological mechanisms.
- Synthesis of treatment approaches for capillary leak syndrome.
Main Results:
- CLS presents with edema, effusions, pulmonary edema, hypotension, and potential organ failure.
- Diverse conditions including Clarkson's disease, engraftment syndrome, and drug reactions can cause CLS.
- Acute kidney injury is a common complication, influenced by cytokines and hypotension.
Conclusions:
- Capillary leak syndrome encompasses a range of diseases with a common mechanism of increased vascular permeability.
- Effective fluid management is crucial but challenging due to ongoing leakage.
- Understanding non-sepsis causes is vital for timely diagnosis and appropriate management.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
