Aspectos diferenciales de la nutrición en los pacientes ancianos con diabetes

[Differential characteristics of type 2 diabetes in the elderly. Role of dipeptidyl peptidase 4 inhibitors]

The prevalence of type 2 diabetes mellitus increases with age, reaching rates around 30% in those over 75 years. The type 2 diabetes mellitus in the elderly has different pathophysiological and clinical characteristics from those of the younger diabetic patient. Some differential aspects in this population are the lower life expectancy and the frequent comorbidity, frailty and associated disability. Avoiding hypoglycemia is a therapeutic priority, given their increased risk of severe hypoglycemia. It is a situation in which the benefits of intensive glycemic control are virtually non-existent, thus prevention of side effects of treatments becomes a priority. Therefore, the goals of glycemic control should be less stringent than in the general population (glycated hemoglobin>7%), and the drugs of choice should be those with a low risk of side effects (especially hypoglycemia) and well tolerated. Dipeptidyl peptidase 4 inhibitors (iDPP4) are particularly useful in this age group, either as a second drug added to metformin monotherapy, or as first line when metformin is contraindicated or not tolerated. In this article the evidence available on the efficacy and tolerance of different pharmacological options available in population over 70 years is reviewed.

[Treatment of type 2 diabetes in the elderly]

Treatment of type 2 diabetes in the elderly represents a major challenge both in terms of clinical management and public health. Aging is causing a marked increase in the pandemic of diabetes in elderly people. However, scientific evidence to support the most appropriate treatment for diabetes in the elderly is scarce. Given the heterogeneity of the elderly population, which includes subjects with very different functional and cognitive capacities, co-morbidities, and life expectancy, it is critical to make a comprehensive assessment from a biopsychosocial perspective, to address the vascular risk factors integrally, and to establish individually tailored targets for glycemic control. In frail elderly or individuals with a short life expectancy, it may be reasonable to maintain HbA1c between 7.6%-8.5%. The therapeutic strategy for elderly patients with type 2 diabetes should be individualized and agreed with the patient and their caregivers, according to the objective. Improving quality of life, assuring patient safety and avoiding the adverse effects of antidiabetic treatment should be prioritized. Given the increased susceptibility of the elderly to severe hypoglycemia and its consequences, antidiabetic therapies that minimize the risk of hypoglycemic events should be selected.
