Associations between Pre-Bariatric High-Sensitivity C-Reactive Protein and Post-Surgery Outcomes

Area of Science:

• Metabolic Surgery
• Bariatric Surgery Outcomes
• Obesity Medicine

Background:

• Obesity is a chronic inflammatory condition linked to elevated C-reactive protein (CRP).
• Bariatric surgery shows promise in improving inflammatory markers and liver health.
• Investigating the predictive role of pre-surgery hs-CRP in post-bariatric surgery outcomes is crucial.

Purpose of the Study:

• To examine the relationship between pre-surgery high sensitivity-C-reactive protein (hs-CRP) and post-Roux-en-Y gastric bypass outcomes.
• To assess the impact of bariatric surgery on weight loss, liver steatosis, and fibrosis.
• To determine if baseline hs-CRP predicts surgical success and liver status post-procedure.

Main Methods:

• Prospective observational study involving 90 morbidly obese patients undergoing gastric bypass.
• Evaluation of anthropometric data, laboratory markers (including hs-CRP), liver stiffness, and steatosis at baseline and 6 months post-surgery.
• Statistical analysis including correlation and regression to assess relationships between hs-CRP and outcomes.

Main Results:

• Significant reductions in weight, liver stiffness, liver enzymes, nonalcoholic fatty liver disease fibrosis score (NFS), and steatosis grade were observed post-surgery.
• Serum hs-CRP levels decreased significantly from 9.26 ± 8.45 to 3.29 ± 4.41 mg/L (p < 0.001).
• No significant correlations were found between baseline hs-CRP and liver fibrosis, steatosis, NFS, or surgery success rate.

Conclusions:

• Bariatric surgery effectively reduces hs-CRP levels, liver stiffness, and steatosis in morbidly obese patients.
• Pre-surgery hs-CRP levels are not predictive of weight loss success or post-operative liver status.
• These findings highlight the benefits of bariatric surgery on inflammatory markers and liver health, independent of baseline hs-CRP levels.
