This mass screening identified 21 men with low hemolytic complement activity (hypocomplementemia). Early detection of complement deficiencies and associated diseases like hepatitis and glomerulonephritis was possible.

Area of Science:

  • Immunology
  • Clinical Chemistry

Context:

  • Mass screening programs offer opportunities to assess population health.
  • Complement system activity (CH50) is a key indicator of immune function.

Purpose:

  • To investigate the distribution of hemolytic complement activity (CH50).
  • To determine the prevalence of hypocomplementemia and associated disorders in a male Japanese population undergoing mass screening.

Summary:

  • A mass screening of 1340 Japanese men measured CH50 levels.
  • Twenty-one individuals exhibited hypocomplementemia, with identified cases of complement component deficiencies (C5, C9), cold activation, hepatitis B/C, glomerulonephritis, and possible SLE.

Impact:

  • Highlights the utility of CH50 measurement in mass screenings for identifying immune deficiencies.
