Type 2 diabetes mellitus is a pathology of heterogeneous etiology characterized by hyperglycemia resulting from lack of insulin action, insulin secretion, or both, and the population with diabetes mellitus is predicted to be about 439 million worldwide by 2030. Prolong diabetes has been related with microvascular complications especially diabetic nephropathy. DN is the most common complication of type 2 diabetes mellitus, and it is the leading cause of end-stage renal disease worldwide. It is crucial to diagnose patients who are more sensible to develop DN for better control of the process of disease. Several factors and mechanisms contribute to the development and outcome of diabetic nephropathy. Microalbuminuria is an early marker of DN and use it as a routine for screening, but the renal damages may be happening even without microalbuminuria. There are several significant kidney damage and disease biomarkers which helps in early detection of DN. An early biomarker may allow earlier diagnosis, treatment reduces DN prevalence and slows DN progression. Therefore, this review focuses on laboratory biomarkers that are earlier, more validation of an early and specific biomarker could potentially make it possible for early diagnosis, treatment, and retardation of progression of diabetic nephropathy.
Introduction In recent decades, the prevalence and incidence of type 2 diabetes mellitus (T2DM) have increased rapidly and represent a significant public health problem worldwide. Long-term T2DM is associated with microvascular complications such as retinopathy, nephropathy, and neuropathy. Prediabetes is a state of hyperglycemia with blood glucose levels higher than normal but lower than the diabetes threshold. Several studies have demonstrated the effectiveness of lifestyle interventions that resulted in a 40% to 70% reduction in diabetes mellitus in adults with prediabetes. These interventions focused on increased physical activity and dietary changes that were able to prevent or delay the onset of T2DM in prediabetes. However, most review studies focused on interventions to prevent T2DM in high-risk groups such as obesity. There was a limitation of reports related to prediabetes. Nevertheless, it remains a high-risk condition for the development of T2DM with a conversion rate of 5% to 10% per year. Therefore, the aim of this study was to review the current evidence on intervention studies aimed at reducing the incidence of type 2 diabetes in prediabetes. Method The researcher conducted a literature search of common online databases such as Medline, Google Scholar, and Cochrane Library between January 2011 and December 2021. Result The intervention for the prevention of T2DM in prediabetes consisted of a lifestyle intervention, a nutritional supplementation intervention, and a pharmacological intervention Conclusion Several studies suggest that T2DM in prediabetes can be prevented by lifestyle modification and pharmacological interventions, or a combined intervention. However, further interventions may be needed to confirm this.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
