Diabetes mellitus is a serious pathologic condition that is responsible for major healthcare problems worldwide and costing billions of dollars annually. Insulin replacement therapy has been used in the clinical management of diabetes mellitus for more than 84 years. The present mode of insulin administration is by the subcutaneous route through which insulin is presented to the body in a non-physiological manner having many challenges. Hence novel approaches for insulin delivery are being explored. Challenges to oral route of insulin administration are: rapid enzymatic degradation in the stomach, inactivation and digestion by proteolytic enzymes in the intestinal lumen and poor permeability across intestinal epithelium because of its high molecular weight and lack of lipophilicity. Liposomes, microemulsions, nanocubicles, and so forth have been prepared for the oral delivery of insulin. Chitosan-coated microparticles protected insulin from the gastric environment of the body and released intestinal pH. Limitations to the delivery of insulin have not resulted in fruitful results to date and there is still a need to prepare newer delivery systems, which can produce dose-dependent and reproducible effects, in addition to increased bioavailability.

Treatment Of Diabetes

Diabetes mellitus is characterized by a condition known as hyperglycemia which may be controlled through medication and insulin. Current insulin therapy for diabetes mellitus involves frequent dosing of subcutaneous injections, causing local discomfort, patient incompliance, hypoglycemia, and hyperinsulinemia, among others, one of the approaches to overcoming these issues is to administer insulin through oral route. An oral form of insulin has been the elusive goal for many investigators since the protein initial discovery by Banting and Best in 1922. Oral delivery of insulin is one of the promising and anticipated areas in the treatment of diabetes, primarily because it may significantly improve the quality of life of patients who receives insulin regularly. However, there are several challenges in developing an oral route for insulin delivery; include low bioavailability due to rapid enzyme degradation in the stomach, inactivation, and digestion by proteolytic enzymes in the intestinal lumen, poor permeability, and poor stability. Several companies have developed technology platforms that protect polypeptides and proteins from enzymatic hydrolysis, enable their transport across the epithelial lining, and promote their absorption from the GI tract. Most notably, the use of permeation enhancers, protease inhibitors, enteric coatings, and polymer microsphere formulation will be covered, including commentary on which methods hold more promise towards the successful development of oral insulin. This review, considers the current literature on the advances, methods, needs, and challenges in the development of oral insulin.

The advancement of the oral route for macromolecules has gained a lot of attention due to its noninvasive nature, safe and challenging in active research but with limited success. Oral administration poses challenges due to poor solubility, short half-life, quick elimination and the physical, chemical and biological barriers of the gastrointestinal tract. Approaches of past for improving oral absorption, such as enhancers, mucoadhesive delivery and enzyme inhibitors have been taken over by novel approaches like advanced liposomes, self-nanoemulsifying drug delivery system, nanoparticles and targeted delivery. Eudratech™ Pep, Peptelligence, Rani Pill and Pharm Film are the emerging technologies for delivering oral proteins and peptide. Calcitonin, semaglutide and octreotide are the peptides available in the market for oral delivery as outcomes of these technologies.

Apoptosis (programmed cell death) is a natural process that helps in removing potentially harmful cells from the body and replacing it with normal ones. Like any other process, it is also subjected to lots of deregulations and can lead to diseases like cancer, neurodegenerative conditions, multiple sclerosis, Parkinson’s disease, autoimmune disorders and inappropriate death of cells after liver failure, stroke and myocardial infarction. The knowledge of the molecular mechanisms involved in apoptosis has been progressed tremendously. Thus, therapeutics targeting apoptosis have been emerged as a novel approach for treating various disease conditions. Current approaches induce or inhibit apoptosis by targeting the key regulators of apoptosis such as Bcl2 family of proteins, TRAIL, caspases, MDM2, IAPs and p53. While many apoptotic drugs proved its efficacy in preclinical studies, some are already approved and entered the clinical setting. Numerous novel approaches such as antisense therapy, gene therapy, recombinant biologics and combinatorial chemistry are being employed to target these regulators. This review focused on the pathways of apoptosis, various therapeutic targets in apoptosis and the drugs modulating these targets.

Background: In recent times much is talked about of serum ferritin, an acute phase reactant a marker of iron stores in the body and its association with diabetes mellitus. Studies implicate that increased body iron stores and subclinical hemochromatosis has been associated with the development of glucose intolerance, type 2 diabetes and its micro as well as macrovascular complications. Material & Methods: This study was carried out to examine and to observe for any relationship between serum ferritin with Type 2 diabetes mellitus. Our study populations were included 163. Among them 81 type 2 diabetes patients as a case (M=49,F=32, mean 44.68 age in years)and 82 normal healthy individual as a control ( M=35, F=47 , mean 34.71 in years). Results: Majority were healthy outpatients who had come for regular checkup and were matched with controls. Serum ferritin and FBS were estimated and other investigations. Results showed that although Serum ferritin was in the normal range value it was increased in type 2 diabetes patients than in controls and was statistically significant, we did get a positive correlation with duration of diabetes. It can be concluded that there were positive associations between serum ferritin and FBG, age, sex among study groups. Conclusion: In conclusion our study shows that there is significant correlation between increased serum ferritin in diabetes compared to individuals with normal blood sugars in this part and hyper ferritinemia may be one of the causes for development of insulin resistance before overt diabetes.

The main purpose of this study is to investigate the role of citrus leaf extract in carbon tetrachloride-induced hepatic injury and its potential molecular mechanism. Carbon tetrachloride was used to construct hepatic injury animal model. To this end, rats were randomly divided into 4 groups: control, carbon tetrachloride-treated, and two carbon tetrachloride + citrus leaf extract-treated groups. The results show that citrus leaf extract treatment significantly reversed the effects of carbon tetrachloride on the body weight changes and liver index. Besides, treatment with citrus leaf extract also reduced the levels of serum liver enzymes and oxidative stress in a dose-dependent manner. H&E staining and western blotting suggested that citrus leaf extract could repair liver histological damage by regulating AMPK and Nrf-2.

Abstract: Diabetes mellitus (DM) is a chronic disease, and the complications may be life-threatening; however, with proper treatment and control measures, it can be very well-managed. Self-management training and education of diabetes are critical in diabetes care and management. It is essential that patients with diabetes must have a comprehensive understanding of the nature of the disease, risk factors, complications, and possible treatment modalities to attenuate the complications. Over the last few years, DM in Saudi Arabia has been rapidly growing at an alarming rate. It has affected around one-fifth of the adult population, and by 2030, the numbers are predicted to rise further and exceed more than double the present number. An estimated tenfold increase has been reported over the past three decades in Saudi Arabia. However, there has not been much research focusing on understanding the knowledge and awareness of DM in Saudi Arabia as compared to developed nations. This review aims to present an overview of the current knowledge and awareness level of DM among the population of Saudi Arabia through an extensive review of the currently available literature. The review findings could be of immense assistance to the government, healthcare systems, educational institutions, and researchers to develop evidence-based programs, policies, and guidelines towards increasing the knowledge and awareness about diabetes and its management, so that early detection and management can be ensured to control the escalating burden of diabetes, in Saudi Arabia.
