Genetic variations in glucocorticoid receptor genes cause hypersensitivity or resistance in some individuals. This explains varied responses to glucocorticosteroid therapy and guides personalized dosing for patients.

Area of Science:

  • Pharmacogenomics
  • Endocrinology
  • Immunology

Background:

  • Glucocorticosteroids are widely used but exhibit variable patient responses.
  • Individual sensitivity to glucocorticoids differs due to genetic factors.
  • Adverse effects and therapeutic resistance are common clinical challenges.

Purpose of the Study:

  • To investigate the prevalence of hereditary glucocorticoid receptor gene abnormalities.
  • To explain the heterogeneity in patient response to glucocorticosteroid therapy.
  • To differentiate between hereditary and acquired glucocorticoid resistance.

Main Methods:

  • Analysis of genetic variations in the glucocorticoid receptor gene.
  • Review of clinical data on patient responses to glucocorticosteroid treatment.

  • Examination of cytokine profiles at inflammation sites.

    • Main Results:

    • Hereditary gene abnormalities affect 6.6% (hypersensitive) and 2.3% (resistant) of the population.
    • Genetic variations explain differing side effect profiles and therapeutic efficacy.
    • Acquired resistance at inflammation sites, driven by cytokines, is common in rheumatoid arthritis and asthma.

    Conclusions:

    • Genetic screening may predict safe glucocorticosteroid doses.
    • Acquired, localized resistance necessitates alternative immunosuppressive therapies.
    • Understanding glucocorticoid sensitivity is crucial for effective treatment strategies.
