Question: What is the level of immunity against meningococcal infections in patients with systemic lupus erythematosus (SLE) under the age of 19, and is vaccination against meningococcus necessary for these patients, given their susceptibility to infections due to immunosuppressive treatments and disease characteristics?
Finding: Although some of our study patients exhibited serum bactericidal activity against meningococci, most remained seronegative.
Meaning: These findings suggest that patients with SLE who are at risk of meningococcal infection receive appropriate vaccinations.
