Prevention of Cardiorenal Complications with Sodium-Glucose Cotransporter Type 2 Inhibitors: A Narrative Review.

Heart failure (HF) and chronic kidney disease (CKD) are the most frequent first cardiorenal conditions in patients with type 2 diabetes (T2D), which can be exacerbated by other comorbidities, such as hypertension, dyslipidemia, and obesity. To improve their clinical outcomes, patients with T2D need to achieve and maintain glycemic targets, as well as prevent cardiorenal disease onset and progression. Several clinical trials evaluating the sodium-glucose cotransporter type 2 inhibitors (SGLT2i) dapagliflozin, empagliflozin, canagliflozin, and ertugliflozin have shown consistent risk reduction in major adverse cardiovascular events and/or hospitalization for HF, together with lower risk of kidney disease progression. The benefits associated with SGLT2i in T2D are distinct from other antihyperglycemic drugs since they have been proposed to exert pleiotropic metabolic and direct effects on the kidney and the heart. In this review, we summarize and discuss the evidence regarding the mechanisms of action, the efficacy and safety profiles, and the clinical guidelines on the use of the therapeutic class of SGLT2i, highlighting their role in cardiorenal prevention beyond glycemic control.

Prevalence of Malnutrition and Nutritional Characteristics of Patients With Inflammatory Bowel Disease.

BACKGROUND AND AIMS: This study sought to determine the prevalence of malnutrition in patients with inflammatory bowel disease, to analyse the dietary beliefs and behaviours of these patients, to study their body composition, to evaluate their muscular strength and to identify the factors associated with malnutrition in these patients. METHODS: This was a prospective, multicentre study. Crohn's disease and ulcerative colitis patients from 30 Spanish centres, from the outpatient clinics, were included. A questionnaire of 11 items was applied to obtain data from patients' dietary behaviour and beliefs. Patients who accepted were evaluated to assess their nutritional status using Subjective Global Assessment and body mass index. Body composition was evaluated through bioelectrical impedance. RESULTS: A total of 1271 patients were included [51% women, median age 45 years, 60% Crohn's disease]. Of these, 333 patients underwent the nutritional evaluation. A total of 77% of patients declared that they avoided some foods to prevent disease relapse. Eighty-six per cent of patients avoided some foods when they had disease activity because of fear of worsening the flare. Sixty-seven per cent of patients modified their dietary habits after disease diagnosis. The prevalence of malnutrition was 16% [95% confidence interval = 12-20%]. In the multivariate analysis, history of abdominal surgery, active disease and avoidance of some foods during flares were associated with higher risk of malnutrition. CONCLUSIONS: The prevalence of malnutrition in inflammatory bowel disease patients was high. We identified some predictive factors of malnutrition. Most of the patients had self-imposed food restrictions, based on their beliefs.

Safety and efficacy of repaglinide in combination with metformin and bedtime NPH insulin as an insulin treatment regimen in type 2 diabetes.

OBJECTIVE: To evaluate the efficacy and safety of the association of repaglinide, metformin and bedtime NPH insulin compared to two classic regimens: metformin plus NPH and two doses of NPH in patients with poorly controlled type 2 diabetes despite two or more oral antidiabetic drugs (OADs). PATIENTS AND METHODS: Random, parallel and open study of 24 weeks with 37 patients randomized into three therapeutic groups: group A (n=12) (repaglinide/metformin/NPH), group B (n=12) (metformin/NPH) and group C (n=13) (NPH/NPH). The insulin was adjusted in the visits to obtain a basal blood glucose <110 mg/dl. The endpoint criteria included HbA1c, blood glucose profile, hypoglycemias and body weight. RESULTS: At the end of the study, group A presented HbA1c (mean+/-standard deviation) 7.2+/-0.7%, which was significantly less than B (8.8+/-0.1%) and C (8.4+/-1.2%). In terms of absolute reduction, there were only differences (p=0.01) between group A (-2.4+/-1.1%) and B (-0.7+/-1.2%). Group A presented lower postprandial blood glucose values (p<0.01). Nor were there any significant differences in weight gain and incidence of hypoglycemia. CONCLUSIONS: The combination of repaglinide, metformin and bedtime NPH is safe and effective and it provides better postprandial blood glucose control. The association of metformin and a dose of NPH does not obtain suitable control in patients with a long evolution who have already received two or more OADs.
