Summary

Systemic capillary leak syndrome (SCLS) is a rare disorder causing severe fluid shifts. Early diagnosis and albumin treatment can improve outcomes for patients experiencing SCLS episodes.

Background:

Systemic capillary leak syndrome (SCLS) is a rare disorder characterized by episodic, unexplained capillary hyperpermeability.
SCLS can lead to severe hypovolemic shock, anasarca, hemoconcentration, and hypoalbuminemia.
The prognosis for SCLS is generally poor, with limited treatment options.

Observation:

A 40-year-old woman presented with severe hypovolemic shock and anasarca, indicating significant fluid imbalance.
Laboratory results revealed marked hemoconcentration and decreased total serum protein, with the presence of monoclonal IgG-lambda.
The patient had a history of a similar episode of generalized edema two years prior, suggesting a recurrent condition.

Findings:

The patient was diagnosed with typical systemic capillary leak syndrome (SCLS) based on clinical presentation and laboratory findings.

Treatment with albumin-containing fluid infusion led to gradual improvement in the patient's condition.

The presence of monoclonal IgG-lambda may be associated with SCLS, warranting further investigation into potential links.

Implications:

This case highlights the importance of recognizing SCLS, a rare but potentially fatal condition.
Prompt diagnosis and supportive care, including albumin administration, can improve outcomes in SCLS patients.
Further research into the etiology and pathogenesis of SCLS is necessary to develop more targeted and effective therapies.
