Circulating immune complexes are present in sickle cell anaemia patients even when asymptomatic. Elevated proteins, IgM C3, and factor B were found in a specific serum fraction, indicating immune activity during the steady state.

Area of Science:

  • Hematology
  • Immunology
  • Clinical Medicine

Background:

  • Sickle cell anaemia is a complex genetic blood disorder.
  • Immune system dysregulation is implicated in sickle cell anaemia pathogenesis.
  • The presence of immune complexes in sickle cell anaemia requires further investigation.

Purpose of the Study:

  • To investigate the presence and composition of immune complexes in sickle cell anaemia patients.
  • To analyze serum fractions for specific immune markers during the steady state.
  • To determine if immune complexes are detectable in asymptomatic sickle cell anaemia.

Main Methods:

  • Studied a polyethylene-glycol insoluble serum fraction.
  • Analyzed patients with sickle cell anaemia during the disease's steady state.

  • Measured levels of C1q-precipitins, total proteins, IgM C3, and factor B.

    • Main Results:

    • C1q-precipitin levels were normal in the studied patients.
    • Increased amounts of total proteins, IgM C3, and factor B were detected.
    • These components were found in the immune complex-enriched serum fraction.

    Conclusions:

    • Circulating immune complexes can be detected in sickle cell anaemia patients.
    • Immune complex presence is evident even during the asymptomatic steady state.
    • Findings suggest ongoing immune activity in sickle cell anaemia patients.
