It is well established that inhibition of dipeptidyl peptidase (DPP)-IV reduces glucose levels and preserves pancreatic beta cell function in patients with type 2 diabetes. DPP-IV inhibitors stimulate insulin secretion as well as insulin biosynthesis and inhibit glucagon secretion from pancreas by increasing incretin (GLP-1) levels. Recent studies reported that combination therapy with DPP-IV inhibitors and other oral antidiabetic medication have additive or synergistic effects in lowering glycose level, preserving beta-cell mass and function as well as enhancing insulin sensitivity. However, there have been few studies about the glucose lowering effect of DPP-IV inhibitors in patients with type 2 diabetes on insulin treatment.
The researchers hypothesized that DPP-IV inhibitor add-on therapy to insulin treatment may have favorable effects on glucose control and endogenous insulin secretory function in type 2 diabetic patients. The researchers plan to compare between sitagliptin (DPP-IV inhibitor) add-on therapy and insulin dose increase therapy in uncontrolled type 2 diabetes on insulin treatment.

Dipeptidyl-peptidase-4 (DPP-4) inhibitors, as the most recent available anti-diabetic agents, were generally used in clinical treatment of type 2 diabetes (T2DM). In addition to anti-diabetic effects,...
In Asia, patients with type 2 diabetes mellitus (T2DM) often have suboptimal glycemic control for many years prior to initiating basal insulin. Active titration of basal insulin is also required to im...
To assess the efficacy and safety profile of the dipeptidyl-peptidase-4 inhibitor sitagliptin in a population of self-identified Hispanic/Latino patients with type 2 diabetes.
A pharmaceutical preparation of sitagliptin phosphate and metformin hydrochloride that is used in the treatment of TYPE 2 DIABETES.
A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.
A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).
Diabetes mellitus induced by PREGNANCY but resolved at the end of pregnancy. It does not include previously diagnosed diabetics who become pregnant (PREGNANCY IN DIABETICS). Gestational diabetes usually develops in late pregnancy when insulin antagonistic hormones peaks leading to INSULIN RESISTANCE; GLUCOSE INTOLERANCE; and HYPERGLYCEMIA.
A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.
Pancreatitis Acute pancreatitis is inflammation of the pancreas caused by the release of activated pancreatic enzymes. Common triggers are biliary tract disease and chronic heavy alcohol intake. Diagnosis is based on clinical presentation...
