Obesity Surgery / Reduction of Premature Aging Markers After Gastric Bypass Surgery in Morbidly Obese Patients
Background
Obesity is considered to be a major comorbidity. Obese patients suffer from an increased proinflammatory state associated with a premature aging phenotype including increased secretion of senescence-associated secretory proteins (SASP) and reduced telomere length. Micro-ribonucleic acids (miRNAs) are non-coding RNA molecules that could modify the post-transcriptional process. Several studies have reported associations between miRNAs and metabolic unhealthy conditions.
Aim
To determine if bariatric surgery and the resulting weight loss could reverse the premature aging phenotype.
Methods
We enrolled 58 morbidly obese patients undergoing bariatric surgery. Markers of premature aging including the SASP IL-6, CRP and PAI-1, 7 miRNAs, as well as telomere length and telomere oxidation in mononuclear cells were evaluated.
Results
Patients showed a significant drop of body mass index (BMI; 43.98 3.5 versus 28.02 4.1, p < 0.001). We observed a significant reduction in SASP including a reduction of 55% of plasma IL-6 levels (p =(VLID)359165
