Summary

Women with polymyalgia rheumatica (PMR) and temporal arteritis (TA) exhibit more severe inflammatory responses and distinct disease presentations. These factors may contribute to the longer treatment durations observed in female patients with PMR and TA.

Area of Science:

  • Rheumatology
  • Immunology
  • Internal Medicine

Background:

  • Sex-specific differences in treatment outcomes for polymyalgia rheumatica (PMR) and temporal arteritis (TA) are documented, with women experiencing longer treatment courses.
  • Understanding the underlying reasons for these disparities is crucial for optimizing patient care.

Purpose of the Study:

  • To investigate whether sex differences in disease presentation and inflammatory response severity contribute to observed treatment outcome variations in PMR and TA.
  • To compare clinical and laboratory features between male and female patients diagnosed with PMR and/or TA.

Main Methods:

  • Retrospective review of 163 patient records diagnosed with PMR and/or TA over a 15-year period.
  • Comparative analysis of clinical manifestations and laboratory markers between male and female patient cohorts.

Main Results:

  • No significant differences in classic disease manifestations were noted between sexes.
  • Women with TA and PMR more frequently presented with constitutional symptoms (malaise, anorexia, weight loss) and fever.
  • Female patients exhibited more pronounced laboratory abnormalities indicative of inflammation, including higher erythrocyte sedimentation rates and lower hemoglobin levels.

Conclusions:

  • Modest sex-specific differences in disease expression exist for TA and PMR.
  • Evidence suggests a more severe inflammatory response in women with these conditions.
  • The heightened inflammatory response in women may account for the longer treatment durations previously reported.
