Filter by:Posttransplantation diabetes mellitus after kidney transplantation mediated by tacrolimus is mainly dependent on dose and peak plasma concentration. To substantiate the potential benefits on glucose metabolism and lipid profile of LCP-tacrolimus compared to standard twice-daily tacrolimus after kidney transplantation, a prospective randomized intraindividual cross-over conversion trial with a comprehensive assessment of glucose metabolism and lipid profile is performed. Primary endpoint is the difference in insulin secretion between treatments, as the principal parameter affected by tacrolimus peak concentrations. Aim of the study is, to assess glucose metabolism under different tacrolimus formulations (LCP-tacrolimus and twice-daily tacrolimus).
RELEVANCE: Up to 50% of patients without previously known disorders of glucose metabolism develop posttransplantation diabetes mellitus (PTDM) after renal transplantation, which is associated with cardiovascular events. Although PTDM is triggered by immunosuppressive agents (calcineurin inhibitors, glucocorticoids), there is consensus against switching patients from potent tacrolimus to the less diabetogenic cyclosporin. Full-blown PTDM must therefore be treated aggressively. Empagliflozin inhibits sodium-glucose cotransporter 2 in the proximal tubule of the kidney and dramatically reduced cardiovascular risk in type 2 diabetics in a recent randomized trial. Especially in diabetics with impaired renal function, empagliflozin was safe, well tolerated, and effective against hyperglycemia and against high blood pressure. Data on SGLT2 inhibition after transplantation are completely lacking. Therefore, the potential antidiabetic of choice is currently withheld from the vulnerable PTDM population. METHODS, STUDY DESIGN: Prospective, single-center, non-inferiority study. Inclusion criteria: PTDM (antidiabetic therapy ≥6 months, based on prior 2-h BG ≥200 mg/dL, fasting BG ≥125 mg/dL (2 times) or HbA1c ≥6.5%); stable renal allograft function >6 months; eGFR ≥30 mL/min/1.73m2. Most important exclusion criteria: type 1 and 2 diabetes; insulin demand >40 IU/day; HbA1c >8.5%. After study inclusion, patients will record 4 weeks of 4-times daily BG measurements before undergoing an OGTT, lab work and urine analysis (including ketones, urinary culture). Empagliflozin (10 mg) will be started and insulin discontinued within 3 days. Patients will be asked to perform urinary dipstick tests at home (i.e. ketones), and to continue recording BG. Study visits at 2 and 4 weeks (second OGTT + lab work (as above)). If control over hyperglycemia is insufficient, insulin therapy will be added back, otherwise study patients remain on empagliflozin monotherapy for 1 year. Statistics will include the paired t-test.
The purpose of this study is to determine whether sitagliptin is effective in preventing the development of new-onset diabetes after kidney transplant (NODAT). Up to one-third of previously non-diabetic patients develop NODAT after a kidney transplant. Corticosteroids and calcineurin inhibitors are two commonly utilized anti-rejection medications that contribute to diabetes development through multiple mechanisms; including decreased insulin production by the pancreas. Sitagliptin is an oral medication that results in increased insulin secretion. We hypothesize that administration of sitagliptin to transplant recipients identified to be at risk for diabetes development will reduce the incidence and severity of NODAT.
The objective of the present study is to evaluate both the efficacy and safet of nateglinide in renal transplanta recipients with posttransplant diabetes mellitus or impaired glucose tolerance. Primarily will the change in glucose tolerance and acute insuline responce be addressed.
