Dyslipidemia Associated With Type II Diabetes Mellitus

Statins are the cornerstone of cardiovascular disease (CVD) prevention through the lowering of low-density lipoprotein cholesterol (LDL-C). While the benefits of intensive LDL-C lowering are well-established for secondary prevention, evidence remains insufficient for primary prevention in the elderly-specifically for individuals aged 70 years or older with type 2 diabetes who have no prior history of atherosclerotic cardiovascular events. Current guidelines generally recommend moderate-intensity statins for this population based on extrapolated data. However, there is a significant evidence gap regarding whether these older adults, who have not yet experienced a cardiovascular event, derive the same risk-benefit ratio from pharmacological intervention as younger or secondary prevention groups. Furthermore, while ezetimibe (alone or in combination) is an effective alternative for patients with established disease, its efficacy as a primary prevention strategy in older diabetic patients has not been rigorously confirmed through randomized controlled trials (RCTs). Therefore, this study specifically focuses on the primary prevention setting, aiming to determine whether individualized LDL-C target-based therapy is non-inferior to standard moderate-intensity statin therapy in preventing first-time cardiovascular events among older patients with type 2 diabetes.

The purpose of this study is to evaluate the efficacy and safety of Berlim 25/20 association in the treatment of type 2 diabetes mellitus and dyslipidemia.

In this project, the investigators will perform a multicenter randomised controlled trial to determine whether advice to consume a moderate, whole food-based low-carbohydrate high-fat (LCHF) ad libitum diet (CarbCount program) can produce and maintain equal remission rates of type 2 diabetes (T2D) as a nutritionally complete very-low-calorie formula diet followed by a energy-restrictive (i.e., calorie counting) diet (DiRECT principles). Within the principles of each approach, the dietary goals and change will be adjusted according to individual needs/capabilities conducive to long-term adherence. Furthermore, the investigators aim to determine whether the rate of diet-induced remission is reflected in/can be predicted by baseline or diet-induced changes in glucose variability (e.g., time-in-range measured by continuous glucose monitoring) and other factors such as anthropometric changes and genetic susceptibility. Each center will also conduct locally-lead standalone mechanistic research, including analyses of intra-abdominal/hepatic fat accumulation, adipose tissue biopsies and/or measurements of energy metabolism. Additionally, changes in medication use, nutritional status, cardiovascular disease risk, as well as adverse events, will be monitored.
