    This study found that higher factor concentrate use in hemophilia patients correlated with impaired cell-mediated immunity, indicated by lower helper-suppressor ratios and increased splenomegaly. Immune function did not significantly change over time with continued concentrate use.

    Area of Science:

    • Immunology
    • Hematology

    Background:

    • Hemophilia management involves factor concentrate infusions.
    • Cell-mediated immunity can be affected in chronic diseases.

    Purpose of the Study:

    • To investigate the association between factor concentrate use and cell-mediated immunity in hemophilia patients.
    • To assess changes in immune status over time.

    Main Methods:

    • Cross-sectional study of 35 hemophilia patients.
    • Analysis of T-cell subsets, helper-suppressor ratio, and clinical signs (splenomegaly, lymphadenopathy).
    • Correlation with factor concentrate use over different time intervals (1 year, 5 years, lifetime).

    Main Results:

    • Significant negative correlation between helper-suppressor ratio and concentrate use.

  • Splenomegaly significantly associated with concentrate use.
  • High prevalence of hypergammaglobulinemia, anergy, and lymphadenopathy.
  • No significant changes in T-cell subsets or clinical condition during follow-up related to concentrate use.

    • Conclusions:

    • Factor concentrate use in hemophilia is associated with markers of impaired cell-mediated immunity.
    • While initial associations exist, prolonged concentrate use did not lead to significant changes in T-cell subsets or clinical status during the study period.
