Systemic Capillary Leak Syndrome (SCLS) is a rare, life-threatening disorder characterized by recurrent episodes of severe hypotension (low blood pressure) and hypoalbuminemia (low albumin levels in the blood). It is caused by a leak of fluid from the capillaries into the surrounding tissues, resulting in a decrease in the amount of fluid in the bloodstream. Symptoms of SCLS include fatigue, dizziness, nausea, abdominal pain, and shortness of breath. Treatment typically involves medications to reduce the leak of fluid from the capillaries and to increase blood pressure.

The main symptom of Systemic Capillary Leak Syndrome (SCLS) is recurrent episodes of severe hypotension (low blood pressure) and fluid leakage from the capillaries into the surrounding tissues. Other symptoms may include:

-Fatigue

-Nausea

-Vomiting

-Diarrhea

-Abdominal pain

-Muscle weakness

-Difficulty breathing

-Confusion

-Lightheadedness

-Fainting

-Rapid heart rate

-Low urine output

-Swelling of the extremities

-Skin rash

-Joint pain

-Weight gain

-Decreased appetite

-Decreased urine output

-Decreased blood pressure

-Decreased blood oxygen levels

The exact cause of Systemic Capillary Leak Syndrome (SCLS) is unknown. However, it is believed to be an autoimmune disorder, meaning that the body’s immune system mistakenly attacks healthy cells and tissues. Other possible causes include genetic mutations, viral infections, and certain medications.

The treatments for Systemic Capillary Leak Syndrome (SCLS) vary depending on the severity of the condition. Generally, treatments focus on managing symptoms and preventing further episodes. These may include:

1. Corticosteroids: These medications help reduce inflammation and can be used to treat SCLS episodes.

2. Immunosuppressants: These medications help reduce the body’s immune response and can be used to prevent further episodes.

3. Plasma Exchange: This procedure involves removing and replacing the patient’s plasma with donor plasma. This can help reduce the severity of SCLS episodes.

4. Intravenous Immunoglobulin (IVIG): This is a treatment that involves infusing the patient with antibodies from healthy donors. This can help reduce the severity of SCLS episodes.

1. Certain medications, such as interferon alpha, interleukin-2, and cyclosporine
2. Autoimmune diseases, such as lupus, rheumatoid arthritis, and Sjogren's syndrome
3. Infections, such as HIV, hepatitis C, and cytomegalovirus
4. Cancer, such as lymphoma and leukemia
5. Radiation therapy
6. Allergic reactions
7. Genetic predisposition

At this time, there is no known cure for Systemic Capillary Leak Syndrome (SCLS). Treatment is focused on managing symptoms and preventing complications. Medications used to treat SCLS include diuretics, corticosteroids, and immunosuppressants. Other treatments may include intravenous fluids, plasma exchange, and supportive care.
