This study found low frequencies of anticardiolipin and antinuclear antibodies in stroke patients. Routine screening for these autoantibodies in stroke populations may not be clinically valuable.

Area of Science:

  • Neurology
  • Immunology
  • Clinical Medicine

Background:

  • Stroke is a significant cause of morbidity and mortality.
  • Autoantibodies, such as anticardiolipin and antinuclear antibodies, have been implicated in some stroke cases.
  • Understanding the prevalence and significance of these antibodies in stroke is crucial for diagnosis and management.

Purpose of the Study:

  • To determine the frequency of anticardiolipin and antinuclear antibodies in a diverse stroke patient cohort.
  • To evaluate the clinical significance and diagnostic utility of these autoantibodies in stroke.

Main Methods:

  • Prospective, multicenter study involving 481 consecutive ischemic or hemorrhagic stroke patients.
  • Plasma samples analyzed for IgM and IgG anticardiolipin antibodies using standardized enzyme-linked immunosorbent assay.

  • Sera screened for antinuclear antibodies via indirect immunofluorescence on mouse liver and kidney sections.

    • Main Results:

    • Anticardiolipin antibodies detected in 1.04% of patients (5/481); antinuclear antibodies in 7.2% (35/481).
    • No anti-DNA antibodies were found in any patient.
    • The observed frequencies were potentially lower than previously reported.

    Conclusions:

    • The prevalence of anticardiolipin antibodies in this stroke population appears low.
    • Routine screening for anticardiolipin and antinuclear antibodies in unselected stroke patients has questionable clinical value.
    • Further research may be needed to clarify the role of specific autoantibodies in certain stroke subtypes.
