E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
The only indication for pancreas-transplantation (PTx) is advanced and/or badly controlled diabetes mellitus. Patients who have developed renal insufficiency due do diabetic nephropathy may be candidates for combined kidney- and pancreas-transplantation (SPK). While patients with "brittle diabetes" (without kidney failure), involving severe hypoglycemic episodes and "unawareness", may be candidates for solitary PTx. Anyway, high-levelled immunosuppression will be needed after PTx/SPK. |
Den eneste indikasjonen for pancreas-transplantasjon (PTx) er langtkommen/dårlig regulert diabetes mellitus. Pasienter som har utviklet diabetisk nyresvikt kan være kandidater for kombinert nyre- og pancreas-Tx (SPK). Mens "skjøre" diabetes-pasienter, uten nyresvikt, men med alvorlige hypoglykemiske episoder, kan tilbys solitær PTx. Uansett vil høygradig immunsuppresjon være nødvendig etter PTx/SPK. |

E.1.1.1 | Medical condition in easily understood language |
Patients with advanced or badly controlled diabetes may be candidates for pancreas transplantation (Tx). If complicated with renal insufficiency, combined kidney and pancreas-Tx may be offered. |
Pasienter med alvorlig eller lanktkommen sukkersyke kan tilbys bukspyttkjertel-transplantasjon (Tx). Ved kompliserende nyresvikt kan det være aktuelt med kombinert nyre- og bukspyttkjertel-Tx.

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Several studies have shown acceptable results after Pancreas transplantation (PTx) by substituting ATG with basiliximab, which is considered to convey a considerably lower number of adverse events. However, the issue of ATG vs basiliximab in PTx has not yet been solved. The potential advantages of reducing the overall cortiocosteroid (CS) load is obvious, as CS is a well-known pro-diabetic agent and causes severe long term adverse effects. On this background, we intend to investigate a PTx low-grade immunosuppressive protocol, with Basiliximab and low-dose CS versus the conventional protocol with ATG and high-dose CS. The primary aim will be to monitor the incidence of rejections, with particular attention to the low-immunosppressive arm. Furtehermore, we will look for a potential benefit regarding the rate of surgical complications in the low-immunosppressive arm. |
Høygradig immunsuppresjon (IS) ved PTx er antatt å være medvirkende til den høye raten av kirurgiske komplikasjoner/reoperasjoner (ca. 30% av pasientene). Høygradig IS er åpenbart relatert til de realtivt betydelige infeksiøse komplikasjonene ved PTx. Forbedret overvåkning av rejeksjoner, ved hjelp av endoskopiske, transduodenale biopsier av pancreas-transplantatet (EUSBP), vil kunne legge grunnlaget for en mer lavgradig IS protokoll/arm. Ny kirurgisk PTx-teknikk med enteroanastomose mot nativ duodenum har muliggjort disse biopsiene. Det vil tas protokoll-biopsier etter 3 uker, 6 uker og 1 år, samt indikasjonsbiopsier ved mistanke om rejeksjon. Studien vil bidra til å belyse spørsmålet om IS induksjonsbehandling ved PTx: ATG vs Basiliximab. De primære målene vil således være å overvåke rejeksjonsraten, særlig mhp forsøksarmen, og se etter mulig effekt på komplikasjonsraten

E.2.2 | Secondary objectives of the trial |
• Compare the number and severity of rejection episodes in the pancreas allograft to the ones occurring in the kidney allograft (SPK), and the ones diagnosed by the duodenal segment biopsies. • Compare pancreas graft survival between the study groups. • Monitor kidney (and pancreas) graft survival in SPK. • Compare patient survival between the study groups. • Compare the incidence of non-surgical complications (infections, cardial complications, pulmonary complications and neurological complications). • Analyse possibly useful non-invasive markers of rejection (amylase, C-peptide etc). |
• Sammenligne rejeksjoner (antall/grad) i simultane biopsier av pancreas, duodenal- segment og nyre fra samme pasient. • Sammenligne pankreas graft survival mellom gruppene. • Sammenligne nyre- og pancreas graft survival ved SPK. • Sammenligne pasient survival mellom gruppene. • Sammenligne incidensen av ikke-kirurgiske komplikasjoner (infeksjoner, cardiale komplikasjoner, pulmonale komplikasjoner og neurologiske komplikasjoner). • Studere potensielt anvendbare non-invasive rejeksjonsmarkører (amylase, C-peptide etc) |
