C-reactive protein and erythrocyte sedimentation rate in women with acute pelvic pain

We have measured the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level in 134 consecutive patients with acute pelvic pain. There were statistically significant differences (P < 0.001) in both values between the groups of patients with inflammatory (n = 42) and non-inflammatory (n = 92) causes of pelvic pain. No significant difference was observed between the subgroups within the two groups. Acute pelvic infection caused the highest elevations of ESR and CRP, with pelvic endometriosis provoking less elevations.
