Enzyme that triggers muscle wasting could be key to REVERSING signs of ageing

Posted on by MaryO

The effects can be devastating for patients who can develop features such as muscle wasting and weakness, weight gain, thinning of the bones, diabetes, high blood pressure and heart disease.

Dr Hassan-Smith said: ‘Looking at this particular enzyme seemed like an intriguing way forward.

‘We knew how it works in relation to Cushing’s Syndrome, which is characterised by similar symptoms, and thought it would be worthwhile applying what we knew to the ageing population.’

Abstract

OBJECTIVE:

The aim of this study was to assess CAD risk among obese young men without metabolic risk factors.

DESIGN:

longitudinal study in a historical cohort Methods: Incident CAD during a median follow-up of 6.1 years was assessed among 31,684 young men (mean age 31.2±5.7 years) of the Metabolic, Lifestyle and Nutrition Assessment in Young Adults (MELANY) cohort. Participants were categorized by BMI and the number of metabolic abnormalities (based on the Adult Treatment Panel-III). Metabolically healthy (MH) obesity was defined as BMI≥30 kg/m2 in the presence of normal blood pressure and normal levels of fasting glucose, triglyceride and HDL-cholesterol levels (n=599; 1.9%). Cox proportional hazard models were applied.

RESULTS:

There were 198 new cases of CAD that were diagnosed during 209,971 person-years of follow-up, of which 6 cases occurred among MH obese. The incidence of CAD among MH lean, overweight and obese participates was 0.23, 0.45 and 1.0 per 1,000 person-years, respectively. In a multivariable model adjusted for clinical and biochemical CAD risk factors, a higher CAD risk was observed among MH-obese (HR=3.08; 95%CI=1.10-8.68, p=0.033), compared to MH-normal weight subjects. This risk persisted when BMI was treated as a time-dependent variable, or when fasting glucose, HDL-cholesterol, triglycerides or blood pressure were added to the model. Similar results were also obtained when a more permissive definition of metabolic health was used.

CONCLUSIONS:

Obesity may continue to contribute to increased risk for incident CAD in young men even in the presence of a healthy metabolic profile.
