Complement Deficiency: Follow-up
Updated: May 6, 2009
Follow-up
Deterrence/Prevention
- Prevention of infections and immediate treatment are important aspects of treatment in patients with complement deficiency. Treat acute infections with appropriate antibiotics and prevent with vaccination.
- All routine vaccines are recommended. Meningococcal, pneumococcal, and haemophilus vaccinations are recommended for patients and those who are in close contact with them.
Prognosis
- Properdin deficiency is associated with a high mortality rate.
Miscellaneous
Medicolegal Pitfalls
- Approximately 5-15% of patients with sporadic cases of meningococcal infections are deficient in C6, C7, C8, or C9. Screening for complement deficiencies is justified in all cases of systemic meningococcal disease.
- Screening for complement deficiencies is prudent in patients who present with recurrent infections, especially with encapsulated organisms, particularly patients with normal immunoglobulin (Ig) levels and antibody titers against vaccine antigens.
