ABSTRACT: Background
Long-term change in CRP is not well characterized in the context of RYGB.Objective
To report C-reactive protein (CRP) after Roux-en-Y gastric bypass surgery (RYGB).Setting
Between 2006 and 2009 1770 adults enrolled in a prospective cohort study underwent Roux-en-Y gastric bypass (RYGB) at 1 of 10 U.S. hospitals.Methods
Research assessments were conducted before surgery and annually postoperatively for up to 7 years. This study included those with high-sensitivity CRP assessed before surgery and 1 or more follow-up assessments (n = 1180).Results
Before surgery, participants' median age was 46 years, and the median body mass index (BMI) was 46 kg/m2; 80% were female. Before surgery, mean (95% confidence interval [CI]) CRP was the highest of all time points (1.01 [.95-1.08] mg/L); it then decreased to a nadir of .18 (.15-.22) mg/L at 2 years postoperatively (P < .001). CRP was higher at 7 years (.26 [.22, .29] mg/L) than at 2 years postoperatively (P < .001) but remained lower at 7 years than preoperatively (P < .001). Additionally, only 3.2% (95% CI: 1.6%-4.8%) of participants had elevated CRP (>1 mg/dL) 7 years postoperatively versus 32.9% (95% CI: 30.2%-35.3%) preoperatively (P < .001). Several preoperative factors were associated with following a less favorable CRP trajectory over time, including higher preoperative CRP level, higher BMI, current smoking, and diabetes.Conclusion
The vast majority of adults who underwent RYGB experienced a sustained improvement in CRP throughout 7 years of follow-up with nonelevated values. However, those with higher preoperative CRP and BMI levels and diabetes and who smoke may benefit from additional testing and monitoring to ensure nonelevated inflammation after surgery.
