Diabetes mellitus: new challenges and innovative therapies
EPMA Journal, 2010
Diabetes mellitus is a widespread disease prevalence and incidence of which increases worldwide. The introduction of insulin therapy represented a major breakthrough in type 1 diabetes; however, frequent hyper-and hypoglycemia seriously affects the quality of life of these patients. New therapeutic approaches, such as whole pancreas transplant or pancreatic islet transplant, stem cell, gene therapy and islets encapsulation are discussed in this review. Regarding type 2 diabetes, therapy has been based on drugs that stimulate insulin secretion (sulphonylureas and rapid-acting secretagogues), reduce hepatic glucose production (biguanides), delay digestion and absorption of intestinal carbohydrate (alpha-glucosidase inhibitors) or improve insulin action (thiazolidinediones). This review is also focused on the newer therapeutically approaches such as incretin-based therapies, bariatric surgery, stem cells and other emerging therapies that promise to further extend the options available. Gene-based therapies are among the most promising emerging alternatives to conventional treatments. Some of these therapies rely on genetic modification of non-differentiated cells to express pancreatic endocrine developmental factors, promoting differentiation of nonendocrine cells into β-cells, enabling synthesis and secretion of insulin in a glucose-regulated manner. Alternative therapies based on gene silencing using vector systems to deliver interference RNA to cells (i.e. against VEGF in diabetic retinopathy) are also a promising therapeutic option for the treatment of several diabetic complications. In conclusion, treatment of diabetes faces now a new era that is characterized by a variety of innovative therapeutic approaches that will improve quality-life and allow personalized therapyplanning in the near future.
Diabetes Mellitus (DM) stands as a prominent metabolic disorder characterized by impaired insulin activity and/or secretion, leading to various pathological complications such as nephropathy, retinopathy, and cardiovascular issues. This review delves into the intricacies of Diabetes Mellitus (DM), exploring its sub-types, conventional treatment modalities, and the emerging role of nanotechnology in revolutionizing drug delivery for improved therapeutic outcomes. Pathophysiology of Diabetes Mellitus manifests through aberrations in insulin dynamics, leading to hyperglycemia and subsequent tissue damage. Understanding the underlying pathophysiological mechanisms is crucial for devising effective therapeutic strategies. Classification of Diabetes Mellitus is broadly categorized into Type 1 and Type 2, each with distinct etiological factors and treatment approaches. Type 1 DM necessitates insulin replacement therapy, whereas Type 2 DM is primarily managed through oral hypoglycemic agents. Insulin replacement therapy is the cornerstone of treatment for Type 1 DM. It involves administering exogenous insulin to mimic the physiological insulin secretion that is deficient in individuals with T1DM. This aims to maintain blood glucose levels within a normal range to prevent acute as well as long-term complications. Drug therapy for Type 2 Diabetes Mellitus : The pharmacological armamentarium for Type 2 DM includes Insulin Secretagogues, Biguanides, Insulin Sensitizers, α-Glucosidase Inhibitors, Incretin Mimetics, Amylin Antagonists, and SGLT2 Inhibitors. The Complex pathophysiology of DM demands innovatives therapeutic approaches to enhance drug efficacy and patient adherence. Nanotechology offers promising solutions by enabling targeted drug delivery, improved bioavailability, and reduced dosing frequency. Clinical Implications and Future Perspectives Nanotechnology holds immense potential in revolutionizing diabetes management by addressing the limitations of conventional therapies and enhancing therapeutic efficacy. Future research endeavors should focus on translational studies to validate the clinical utility of nanotechnology-based drug delivery systems. In Conclusion, the integration of nanotechnology into Diabetes management offers a paradigm shift in therapeutic approaches, promising targeted drug delivery, improved bioavailability, and enhanced patient outcomes. Continued research and development in this field are imperative to realize the full potential of nanotechnology in combating the global burden of Diabetes Mellitus. In this article, we endeavor to delve into the pathophysiolgy of Diabetes Mellitus (DM), traditional treatment methods for both Type 1 (T1DM) and Type 2 (T2DM) diabetes, alongside innovative drug delivery strategies for managing Diabetes Mellitus.
The role of nanotechnology in diabetes treatment: current and future perspectives
International Journal of Nanotechnology, 2011
Diabetes is a chronic disease that currently affects approximately 8% of the US population, and that number is expected to increase significantly by the year 2030. It is imperative that effective monitoring and treatment options be available to patients. Nanotechnology is a focal point in diabetes research, where nanoparticles in particular are showing great promise in improving the treatment and management of the disease. Due to their ability to potentially enhance drug delivery to areas where there are barriers or unfavourable environments for macromolecules, nanoparticles are being explored as vehicles for improved oral insulin formulations. The use of nanotechnology in the development of glucose sensors is also a prominent focus in non-invasive glucose monitoring systems. Finally, compelling but relatively unexplored applications of nanotechnology, such as the development of an artificial pancreas, are discussed. Overall, nanotechnology has the potential to significantly impact several areas of current and future diabetes research.

Customary techniques for diabetes management require steady and tedious glucose monitoring (GM) and insulin infusions, affecting quality of life. The worldwide diabetic population is required to increment to 439 million, with roughly US$490 billion in medical services consumptions by 2030, forcing a huge trouble on medical care systems around the world. Ongoing advances in nanotechnology have arisen as promising elective methodologies for the management of diabetes. For instance, implantable nano sensors are being created for nonstop GM, new nanoparticle (NP)- based imaging approaches that evaluate subtle changes in β cell mass can encourage early diagnosis, and nano technology-based insulin delivery strategies are being investigated as novel treatments. Here, we give an all-encompassing rundown of this quickly propelling field gathering all viewpoints relating to the management of diabetes.
Applications of nanotechnology in diabetes
Digest Journal of …, 2008
Nanotechnology offers sensing technologies that provide more accurate and timely medical information for diagnosing disease, and miniature devices that can administer treatment automatically if required. Some tests such as diabetes blood sugar levels require patients to administer the test themselves to avoid the risk of their blood glucose falling to dangerous levels. Certain users such as children and the elderly may not be able to perform the test properly, timely or without considerable pain. Nanotechnology can now offers new implantable and/or wearable sensing technologies that provide continuous and extremely accurate medical information.The purpose of this review is to throw more light on the recent advances and impact of nanotechnology on biomedical sciences to cure diabetes.
