Analysis of Gremlin 1 Levels Following Sleeve Gastrectomy.

Area of Science:

• Endocrinology
• Metabolic Surgery
• Obesity Research

Background:

• Gremlin 1 is an adipokine with known metabolic effects.
• Understanding its role post-bariatric surgery is crucial for metabolic health.
• Sleeve gastrectomy is a common bariatric procedure impacting metabolic parameters.

Purpose of the Study:

• To assess Gremlin 1 levels after sleeve gastrectomy.
• To investigate the association between Gremlin 1 and glycemic/lipid profiles post-surgery.

Main Methods:

• Enzyme-linked immunosorbent assay (ELISA) measured plasma Gremlin 1.
• Evaluated 31 obese males (25-50 years) pre- and post-sleeve gastrectomy (6-12 months).
• Assessed body mass index, insulin, glucose, and lipid profiles.

Main Results:

• Plasma Gremlin 1 levels significantly increased post-surgery (148.19±17.43 to 193.29±19.82 ng/mL).
• Body mass index, insulin, and HOMA-IR significantly decreased.
• Total cholesterol increased, while Gremlin 1 showed no significant post-surgery correlation with insulin.

Conclusions:

• Circulating Gremlin 1 levels are elevated after sleeve gastrectomy.
• Improvements in insulin sensitivity appear independent of Gremlin 1's effects post-surgery.
