Brief Summary

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in developed countries affecting approximately 30 % of the general adult population. It represents an important pathogenic factor in the development of type 2-diabetes and is associated with a high risk of cardiovascular disease. Previous studies of patients with chronic kidney disease (CKD) have demonstrated an increased risk for NAFLD and the presence of both CKD and NAFLD is likely to increase the risk for cardiovascular disease. The present protocol describes a study of the prevalence and etiology of NAFLD among patients scheduled for kidney transplantation and the possible effect of kidney transplantation on NAFLD. The project is a prospective cohort study. The effect of kidney transplantation in patients with prediabetes or normal glucose tolerance compared to healthy controls will be examined regarding development and progression of fat accumulation in the liver. Fat accumulation in the liver will be determined by magnetic resonance (MR) spectroscopy and the prevalence of NAFLD in the two groups will be investigated. A continuous glucose monitoring (CGM) for four days, Dual Energy X-ray Absorptiometry (DEXA) scanning, fibro scanning of the liver, bile acid analysis, metabolomic and lipidomic analysis will also be performed. An oral glucose tolerance test (OGTT) and an intra venous glucose infusion (IIGI) will be performed.

Outcome Measures

Primary Outcomes (1)

  • Changes in relative lipid signal measured by MR spectroscopy in the liver before kidney transplantation compared with three and twelve months after kidney transplantation

    Liver signal is measured by MR spectroscopy (the non-invasive method for determination of NAFLD)

    Kidney transplanted patients: 3 visits á 1 hour (baseline (before transplantation), three months and twelve months after transplantation), Control group: One hour

Secondary Outcomes (14)

  • Prevalence of fibrosis in the liver before and after kidney transplantation measured by fibroscan.

    Kidney transplanted patients: 3 visits x 15 minutes (baseline (before transplantation), three months and twelve months after transplantation), Control group: 15 minutes

  • Prevalence of fibrosis in the liver before and after kidney transplantation measured in clinical index (NAFLD fibrosis score).

    Kidney transplanted patients: 3 visits á one day (baseline (before transplantation), three months and twelve months after transplantation), Control group: One day

  • Prevalence of fibrosis in the liver before and after kidney transplantation measured by clinical index (FIB-4 score).

    Kidney transplanted patients: 3 visits á one day (baseline (before transplantation), three months and twelve months after transplantation), Control group: One day

  • Glycemic variability associated with NAFLD, as measured by MR spectroscopy, before and after kidney transplantation

    Kidney transplanted patients: 4 days x3 visits (baseline (before transplantation), three months and twelve months after transplantation), Control group: 4 days

  • Mean glucose associated with NAFLD, as measured by MR spectroscopy, before and after kidney transplantation

    Kidney transplanted patients: 4 days x3 visits (baseline (before transplantation), three months and twelve months after transplantation), Control group: 4 days

  • +9 more secondary outcomes

Study Arms (2)

Kidney transplanted patients

Number of patients: 16 Patients on the waiting list for kidney transplantation with a living donor. The patients are screened with an OGTT before participation in the study, thereby excluding patients with diabetes mellitus. Patients in this group are examined three times (baseline (before transplantation) and after three and twelve months after transplantation). Same interventions as in the control Group. Including/ Exclusion criteria are listed under the section "Eligibility"

Diagnostic Test: MR spectroscopy of the liverDiagnostic Test: Fibroscan of the liverDevice: Continuous glucose monitoring (CGM) for four days.Diagnostic Test: Oral glucose tolerance test (OGTT)Diagnostic Test: Intra venous glucose infusion (IIGI)Radiation: Dual Energy X-ray Absorptiometry (DEXA) scanBiological: Blood samplesOther: Clinical and demographic data

Control group

Number of patients: 16 Participants in this group are matched on age and BMI according to the kidney transplanted patients. Participants are screened with an OGTT before participation since only persons with normal glucose tolerance may be included in the study. Furthermore, participants have to have normal kidney function. Participants in this group are only examined once. Same interventions as in the kidney transplanted patient group

Diagnostic Test: MR spectroscopy of the liverDiagnostic Test: Fibroscan of the liverDevice: Continuous glucose monitoring (CGM) for four days.Diagnostic Test: Oral glucose tolerance test (OGTT)Diagnostic Test: Intra venous glucose infusion (IIGI)Radiation: Dual Energy X-ray Absorptiometry (DEXA) scanBiological: Blood samplesOther: Clinical and demographic data

Control groupKidney transplanted patients

CGM is attached to the abdominal skin for four days. Afterwards data is converted and analysed in a computer program.
