C-reactive protein as a predictor of infectious morbidity with premature rupture of membranes.
The management of patients with premature rupture of membranes (PROM) poses one of the most serious dilemmas in obstetrics since PROM significantly increases the likelihood of prematurity and serious perinatal infection. Early infection is not reliably predicted nor detected by standard laboratory parameters. Serum C-reactive protein (CRP) levels were assayed along with white blood cell count, differential, and temperature course in patients with PROM and controls. Elevated CRP very accurately divided patients with evidence of infectious morbidity from those without such evidence (p < 0.001). In 109 patients there were 11 false negatives and no false positives. In 14 of 20 patients followed with serial comparisons who developed morbidity, CRP became elevated at least 12 hours prior to any other parameter measured. Changes in the other six patients were concurrent. The results suggest that CRP may be a reliable, early predictor of infectious morbidity and thus may be of benefit in the selective management of patients with PROM.
