Brief Summary

This retrospective multicentre study aims to provide real-world evidence of the effectiveness of Resource® Diabet Plus as supplementation tool for T2DM patients with malnutrition or at risk of malnutrition, under conditions of routine clinical practice in Spain.

Detailed Description

Disease-related malnutrition (DRM) is a nutritional imbalance caused by a nutrient deficiency resulting from one or more underlying pathologies. It is the main cause of malnutrition in developed countries, with a prevalence of around 30 million people in Europe in 2020. In Spain, it is estimated that around 20-50% of hospitalized patients suffer from DRM, both in acute and chronic conditions. One of the chronic diseases where malnutrition is associated with higher mortality and increased hospital admissions is Type 2 Diabetes Mellitus (T2DM), particularly in the elderly. T2DM is currently one of the most prevalent chronic diseases worldwide, affecting about 10% of the adult population in 2021. Approximately 90% of diagnosed cases of diabetes are type 2, which is not autoimmune-mediated, unlike type 1 (T1DM). T2DM typically develops over time due to factors such as obesity, sedentary lifestyle, high-calorie diets, and aging. Additionally, malnutrition risk is increased in patients with T2DM, which leads to a poorer prognosis.

For the treatment of DRM in diabetic patients, as in other chronic conditions, clinical guidelines recommend a personalized nutritional plan tailored to the patient's needs and characteristics, primarily focused on increasing dietary calorie intake. If this is insufficient, oral nutritional supplements may be necessary. From a clinical perspective, oral nutritional supplements address malnutrition while offering clinical and functional benefits. In diabetic and malnourished patients, it is crucial to maintain good metabolic and glycemic control, which requires diabetes-specific formulas (DSFs).

Unlike standard formulas, which are typically high in carbohydrates, low in lipids, and lack dietary fiber, DSFs contain carbohydrates with low glycemic indices and also include fiber. The purpose of these formulas is to improve the nutritional status of patients without negatively affecting their glycemic profile, aiming for adequate glycated hemoglobin (HbA1c) levels - values under 7% are generally recommended for this population.

Prospective observational studies in malnourished T2DM patients have shown that supplementation with a DSF for at least 12 weeks improves patients' functional and nutritional status, enhances biochemical markers, and does not increase postprandial glucose levels. Additionally, the use of these formulas benefits glycemic and metabolic control in the short and medium term, potentially improving diabetes management and its associated comorbidities, while reducing long-term complications and mortality.

A retrospective study conducted in 2015 in the Spanish diabetic population suggested that this type of DSF may reduce HbA1c in the medium term, facilitating glycemic control and reducing the negative effects of glycemic fluctuations. This could result in a reduced need for insulin as an antidiabetic treatment.

The existing evidence supports the benefits of DSFs in diabetic patients by helping to maintain metabolic control and improving nutritional, functional, and clinical outcomes. These improvements are associated with fewer hospital visits and admissions. However, more studies are needed to confirm the advantages of using these nutritional formulas specifically designed for diabetic and malnourished patients. Although they are somewhat more expensive than standard supplements, they help patients achieve better metabolic control, which can ultimately lead to lower healthcare costs.

Few retrospective studies have been conducted in the field of nutrition for diabetic and malnourished patients. Most available data come from prospective studies or literature reviews. However, the nature of retrospective real-world studies allows for the assessment of DSF use in a specific population over a relatively short time period, reflecting how malnourished diabetic patients are managed in clinical practice.

This retrospective study aims to provide real-world evidence on the effectiveness of Resource® Diabet Plus supplementation as a DSF in diabetic patients with malnutrition or at risk, under routine clinical practice conditions in Spain.

OBJECTIVES OF THE STUDY

Primary Objective:

• To assess the effects of Resource® Diabet Plus on glycemic control in patients with T2DM who are malnourished or at risk, 12 and 24 weeks after initiation of nutritional therapy.

Secondary Objectives:

• To assess the effects of Resource® Diabet Plus on metabolic control in malnourished or at-risk T2DM patients at 12 and 24 weeks after treatment initiation.
• To describe the evolution of nutritional and functional status in T2DM patients who are malnourished or at risk, 12 and 24 weeks after starting Resource® Diabet Plus.
• To describe the presence of gastrointestinal symptoms in patients treated with Resource® Diabet Plus.
• To analyze healthcare resource utilization and associated costs after 24 weeks of treatment with Resource® Diabet Plus.

METHODOLOGY

Study Design and Scope:

This is a retrospective, multicenter, single-arm observational study including data from patients at risk of malnutrition identified through validated screening tools or with DRM diagnosed using GLIM criteria, who were prescribed a specific hypercaloric and high-protein formula for diabetic patients: Resource® Diabet Plus. The study will be conducted in the Endocrinology and Nutrition Departments of four Spanish hospitals.

Resource® Diabet Plus must have been prescribed between two years and 24 weeks prior to the study start date. Clinical history data will be collected at the time of prescription (index date, V0), and follow-up data will be collected at 12 weeks (V1) and 24 weeks (V2), allowing a two-week window to adapt to each center's clinical practice. Investigators will have a 3-month window for patient identification and data collection.

Study Product: Resource® Diabet Plus

The study product, Resource® Diabet Plus, is a high-protein and hypercaloric (1.6 kcal/mL) oral nutritional formula with fiber, made from milk protein and 100% soluble fiber. It is suitable for patients with type 1 diabetes, T2DM, or hyperglycemia with increased energy and protein requirements and conditions involving nutritional risk or malnutrition.

Resource® Diabet Plus is presented in 200 mL bottles, each containing:

• 18 g of protein
• 5 g of soluble fiber
• 7.2 g of monounsaturated fatty acids from vegetable oils

Additionally, Resource® Diabet Plus contains slowly absorbed carbohydrates with a glycemic index below 55, making it appropriate for achieving metabolic targets while maintaining glycemic control.
