Aging adults generally maintain spleen function. A study of healthy elderly individuals found only a slight age-related decline, with most participants showing normal splenic function, not disease-related hypofunction.

Area of Science:

  • Gerontology
  • Immunology
  • Hematology

Background:

  • Hyposplenism (reduced spleen function) is reported in the elderly.
  • Previous studies couldn't distinguish age-related changes from disease effects.
  • Hyposplenism increases risks of infection, autoimmune issues, and thrombosis.

Purpose of the Study:

  • To assess splenic function in healthy elderly individuals.
  • To determine if age itself, not disease, affects spleen function.
  • To clarify the clinical significance of age-related splenic alterations.

Main Methods:

  • Assessed splenic function by counting pitted red blood cells.
  • Studied 65 healthy, free-living subjects aged 50-108 years.
  • Excluded participants with underlying health conditions.

Main Results:

  • A higher percentage of pitted red cells was observed in subjects over 70 compared to younger ones.
  • Only one subject exhibited a red cell count indicative of definite splenic hypofunction.
  • A weak positive correlation (rs = 0.273, p = 0.029) was found between age and pitted red cells.

Conclusions:

  • Splenic function is largely maintained in elderly individuals.
  • A slight reduction in splenic function may occur with advanced age.
  • Age-related splenic changes in healthy individuals are minimal and unlikely to cause significant hypofunction.
