What is surfactant protein C deficiency?
Surfactant Protein C Associated Disease This condition has a highly variable presentation, from acute respiratory distress to a more slow-onset and chronic lung disease. It can affect infants, children, and adults. The diagnosis is made by genetic testing for a mutation in SFTPC in the child and both parents.
What does surfactant do in the lungs?
Function. The main functions of surfactant are as follows: (1) lowering surface tension at the air–liquid interface and thus preventing alveolar collapse at end-expiration, (2) interacting with and subsequent killing of pathogens or preventing their dissemination, and (3) modulating immune responses.
Is protein C deficiency curable?
Blood thinner medications, also known as anticoagulants, can treat protein C deficiency. These medications cut your risk for blood clot formation by preventing blood from clotting in blood vessels.
How common is protein C deficiency?
The prevalence of the milder form is about 1 in 200-500 people in the general population. Prevalence is the number of people in a population that have a disorder at a given time. The prevalence of severe protein C deficiency is about 1 in 500,000-750,000 people in the general population.
Why does lack of surfactant cause respiratory distress?
Surfactant enables the lungs to expand more easily. Without surfactant, the air sacs in the lungs, also called alveoli, collapse very easily. This collapse leads to decreased amounts of air in the lungs. The lack of surfactant combined with alveolar collapse makes it very difficult for the infant to breathe.
Does RDS go away?
The earlier a baby is born, the more likely they are to have RDS that cannot be prevented. Nearly all babies born before 28 weeks of pregnancy will have RDS. With treatment, many newborns that are diagnosed with RDS will recover.
Which pressure keeps the lungs from collapsing?
intrapulmonary pressure
intrapulmonary pressure is what keeps the lungs from collapsing (atalectasis) due to their natural elasticity. causes lung collapse. oblique and transverse abdominus muscles, internal intercostals, and the latissimus dorsi. Valsalva’s maneuver-Forced expiration against closed glottis .
Why is surfactant important to the respiratory system?
Pulmonary surfactant is essential for life as it lines the alveoli to lower surface tension, thereby preventing atelectasis during breathing. Surfactant is enriched with a relatively unique phospholipid, termed dipalmitoylphosphatidylcholine, and four surfactant-associated proteins, SP-A, SP-B, SP-C, and SP-D.
Is protein C deficiency an autoimmune disease?
However, two recent reports have linked a large number of autoimmune disorders/immune-mediated disease to an increased risk of PE and VTE [34,35]….Table 1.
| Inherited risk factors | Acquired risk factors |
|---|---|
| Protein C deficiency (PROC) | Infections |
| Protein S deficiency (PROS1) | Inflammatory disease |
Can protein deficiency fatal?
Without treatment, purpura fulminans can be fatal. People with the milder form of protein C deficiency may not show any symptoms (asymptomatic) until they reach adulthood. Others may remain asymptomatic. The most common symptom is deep vein thrombosis.
How long can you live with one collapsed lung?
Doctors call the surgery to remove a lung a pneumonectomy. Once you’ve recovered from the operation, you can live a pretty normal life with one lung. You’ll still be able to do normal, everyday tasks without a problem. The surgery doesn’t seem to cause any issues for the remaining lung.
How long can respiratory distress syndrome last?
Many people with ARDS recover most of their lung function within several months to two years, but others may have breathing problems for the rest of their lives. Even people who do well usually have shortness of breath and fatigue and may need supplemental oxygen at home for a few months.
How long does it take for a collapsed lung to heal?
Follow-up after a collapsed lung consists of an outpatient physical examination by your doctor and repeat X-rays in the short term. Recovery from a collapsed lung generally takes about one to two weeks.
Can a collapsed lung heal?
Most people who have a collapsed lung generally heal without major treatment. If you’ve had a collapsed lung, you have a higher chance of having it again.
Can respiratory distress syndrome be cured?
There is no cure for ARDS at this time. Treatment focuses on supporting the patient while the lungs heal. The goal of supportive care is getting enough oxygen into the blood and delivered to your body to prevent damage and removing the injury that caused ARDS to develop.
What is deficiency of surfactant protein C?

What is the prognosis of surfactant protein deficiency?
The diagnosis of a surfactant protein deficiency is made through genetic testing of the child and both parents. The prognosis of the lung disease is variable, depending on the severity of the disease.
Is SP-C critical for surfactant function?
In summary, SP-C is a hydrophobic protein that inserts into the surfactant monolayer but does not appear to be critical for surfactant function. However, mutations in this protein and total absence can result in interstitial lung disease.
How is surfactant protein deficiency diagnosed in children?
Surfactant Deficiency. The diagnosis of a surfactant protein deficiency is made through genetic testing of the child and both parents. Treatment The prognosis of the lung disease is variable, depending on the severity of the disease. Some children require lung transplantation while others do not.
