Accepted 27 June, 2016 Glucagon-like peptide-1 (GLP-1) based therapy improves glycemic control through multiple mechanisms with a low risk of hypoglycemia. Dulaglutide is administered once weekly via subcutaneous injection. Two dialysis patients has used super-rapid insulin (3 shots/day) and one patient has done insulin aspart/aspart protamine 30/70 (2 shots/day). We switched injection regimen from multiple daily insulin injections to dulaglutide, and had glycemic control improved without hypoglycemia. The choice of injection regimen should consider the preferences, and resources of the individual and the family for adapting treatment of the patient needs. Dulaglutide minimizes the risk of hypoglycemia and injection burden. Key words: GLP-1 receptor agonist, dulaglutide, dialysis patients. INTRODUCTION The American Diabetes Association (ADA) recommends On September 18, 2014, dulaglutide (Trulicity; Eli Lilly), metformin as the initial for type 2 diabetes; if another a once-weekly subcutaneous injection, was approved by treatment or a combination therapy is needed, available the US Food and Drug Administration (FDA) as an agents include sulfonylureas, thiazolidinediones, adjunct to diet and exercise to reduce fasting and dipeptidyl peptidase (DPP)-4 inhibitors, glucagon-like postprandial glucose after a single dose (Indianapolis, peptide (GLP)-1 receptor agonists, insulin, and other 2014). agents (Insucchi et al., 201). The development of the Liraglutide is an analog of human GLP-1 produced by GLP-1 receptor agonist and the DPP-4 inhibitor classes, recombinant DNA technology. It was approved for clinical both of which target the incretin system, represents an use in Europe in 2009 and in USA in 2010 and has been important advancement in the management of type 2 available in India since 2010. We used liraglutide for 3 diabetes (2). The long-acting GLP-1 receptor agonists dialysis patients with type 2 diabetes. improve glycemic control and help to promote weight loss. Furthermore, based on their glucose-dependent mechanism of action, the GLP-1 receptor agonists have Case reports low risk for hypoglycemia (Garber, 2011). The most common adverse effect was mild to moderate Super-rapid insulin has a short duration of action and nausea and vomiting which decreased with time reduces blood glucose in a highly targeted fashion.

The incidence of Premixed insulin regimens are designed to maximize hypoglycemia was low when not given alongside patient convenience and reduce the number of daily concomitant sulfonylurea or insulin therapy (Princeton injections required by providing both rapid-acting and and Bristol-Myers, 2014). GLP-1 based therapies have intermediate-acting components in one formulation. We become integral in many treatment guidelines, such as had three dialysis patients with type 2 diabetes.

We measured human GLP-1 (Rigato and Fadini, 2014). There is no blood glucose levels under hemodiafiltration therapy and structural modification to render it resistant to DPP-4, but showed their results (Table 2). the slow absorption from the site after subcutaneous administration can be attributed to self-association RESULTS leading to the formation of heptamers at the injection site (Rigato and Fadini, 2014).

Liraglutide should be initiated with the dose of 0.6 mg for a week (Rigato and Fadini, 2014; Bagsvaerd, 2013).

In 6 clinical studies which included a total of 3342 patients with type 2 diabetes, treatment with dulaglutide resulted in greater reductions from baseline in HbA1c levels compared with placebo, with no overall differences in glycemic reductions across age, sex, race/ethnicity, or duration of disease (Loretta, 2015). With the recent FDA approval of dulaglutide, a new, once-weekly subcutaneous injection became available as an adjunct to diet and exercise for adult patients with type 2 diabetes. Dulaglutide, a GLP-1 receptor agonist, provides a once-weekly treatment option that can be used as monotherapy or as an add-on therapy to existing treatment regimens. The once-weekly therapy may provide another therapeutic alternative when oral antihyperglycemic medications are unable to provide adequate glycemic control. A once-weekly treatment may provide an attractive option for dialysis patients with type 2 diabetes. Conclusion The GLP-1 receptor agonist improves glycemic control through multiple mechanisms with a low risk of hypoglycemia. Dulaglutide is being recognized as an important therapy in management of dialysis patients with type 2 diabetes. REFERENCES Insucchi SE, Bergenstal RM, Buse JB (2012).
