They demonstrated that in many patients, serum C-reactive protein remains elevated up to 6 weeks despite successful treatment of episodes of peritonitis (mean serum C-reactive protein at baseline 8.8 mg/l and at 6 weeks 40.9 mg/l).[74] Individuals with serum C-reactive protein > 3.0 mg/l at 6 weeks after an episode of peritonitis had a greater risk for death. This evidence concerns the gene CRP and peritonitis.
