Primary | eGFR | Kidney function | 3 months | |
Secondary | eGFR | Kidney function | 12 months | |
Secondary | Urinary biomarkers | NGAL, NAG, KIM-1, TIMP-2, IGFBP7, IL-6, IL-18 and MCP-1 are the biomarkers that the investigators plan to analyze | at inclusion and after3 and 12 months | |
Secondary | Pathology | Re-evaluation of renal biospies performed at time of inclusion. This evaluation includes the use of routine and special staining for inflammation, fibrosis and tubular damage. The analysis includes an estimation of predictive value of histological scoring on treatment response and prognosis | At inclusion | |
Secondary | Need for renal replacement therapy | Dialysis need | 3 and 12 months | |
Secondary | Plasma glucose or hemoglobin A1C | Development of diabetes (safety) | 3 and 12 months | |
Secondary | Treatment delay | In the prednisolone group the importance of "treatment delay" is analyzed. Treatment delay is defined as follows:
Days form first symptoms to inclusion in this project Days from first contact to the Danish health care system to inclusion in this project Days from first contact to a nephrology department to inclusion in this project |
