Summary
Ankylosing spondylitis (AS) may be underdiagnosed in women. Early detection using clinical clues, HLA-B27 testing, and radioisotope scanning is crucial for timely treatment.
Area of Science:
- Rheumatology
- Immunogenetics
Background:
- Ankylosing spondylitis (AS) is often considered rare in women, potentially leading to underdiagnosis.
- Characteristic clinical features in women may be overlooked, delaying diagnosis and appropriate management.
Purpose of the Study:
- To highlight the underestimation of ankylosing spondylitis incidence in women.
- To identify key clinical features suggestive of AS in female patients.
- To emphasize the utility of diagnostic tools for early AS detection.
Main Methods:
- Case study analysis of 12 women diagnosed with ankylosing spondylitis.
- Clinical feature assessment including age of onset, pain characteristics, and physical examination findings.
- Diagnostic testing including HLA-B27 antigen testing and radioisotope (RI) scanning of sacroiliac (SI) joints.
Main Results:
- All 12 patients presented with decreased spine mobility, onset before age 30, night pain, and morning stiffness.
- Sacroiliac (SI) and circumthoracic tenderness were common.
- HLA-B27 antigen was present in 10 of 11 tested patients.
- RI scanning detected SI joint inflammation missed by standard roentgenograms in 3 cases.
Conclusions:
- Ankylosing spondylitis incidence in women may be underestimated.
- Specific clinical clues, HLA-B27 testing, and RI scanning are vital for early and accurate diagnosis.
- Prompt diagnosis prevents mislabeling patients and inappropriate treatment.
