Regarding this new class of drugs, represented by dapaglifozin, canaglifozin and empaglifozin, it is important to highlight the benefits brought by these medications to combat hyperglycemia with insulin-independent mechanisms that are beyond glucose reduction, such as cardiovascular events prevention, reduction in HbA1c, weight loss and blood pressure lowering. Recently, a relevant study (Empa-Reg) brought hope and set the spotlight on the prevention of cardiac events among diabetic patients, which is the main cause of mortality within this group. However, despite coming out as a good treatment option, SGLT2 inhibitors are under constant clinical research and, as a new drug, it should be carefully carried out regarding the long-term effects of glycosuria and other possible side effects, such as the observed increase in the incidence of bladder, breast cancer and bone fractures, which require further studies. Therefore, these compounds might represent a landmark approach for the treatment of diabetes.展开更多

This case report presents two unusual cases of patients with schizophrenia who experienced substantial weight loss while on long-term clozapine therapy. The first case involves a 35-year-old male who lost 21.3% of his initial body weight, and the second case describes a 54-year-old female who lost 30.2% of her initial weight, despite having comorbid hypothyroidism. Both patients showed improvement in psychiatric symptoms concurrent with the weight loss. Comprehensive investigations did not reveal other clear etiologies for the weight reduction. These cases challenge the conventional understanding of clozapine’s metabolic effects and highlight the potential for atypical responses in some individuals. The report discusses possible mechanisms for this unusual phenomenon, including genetic factors and altered pharmacokinetics. It also emphasizes the need for individualized monitoring and management strategies in clozapine therapy. These findings contribute to the growing body of evidence suggesting that metabolic responses to clozapine may be more complex and varied than previously thought, underscoring the importance of personalized approaches in schizophrenia treatment.展开更多

The glucagon-like-peptide-1 (GLP-1) is a glucose dependent hormone produced by intestinal cells, which is involved in insulin secretion and glucagon suppression. This hormone controls glucose plasma levels and reduces food intake. Additional effects were reported in slowing gastric emptying and in inducing satiety. In clinical practice, theGLP-1 receptor agonists are associated with significant reductions in glycosylated hemoglobin (HbA1c) and weight loss, despite showing a low risk of hypoglycemia. Beneficial effects have also been observed on blood pressure and lipid profile. The most common side effects associated with GLP-1 receptor agonists are gastro-intestinal motility disorders, such as nausea, vomiting and diarrhea, which are not associated with long-term health risks. Therefore, GLP-1 receptor agonists represent a relevant medication for type 2 diabetes, whose benefits may go far beyond glycemic control.展开更多
