Assessment of Depression Prevalence and Its Relation With Interleukin 18 One Year After Renal Transplantation

摘要

Renal transplantation is the treatment of choice for many patients with end-stage renal disease. Because there is little information about depression after kidney transplantation, we investigated frequency and determinant factors of depression and also its association with interleukin (IL)-18. Kidney transplant recipients were investigated between January 2011 and February 2013. Depression was assessed using the Beck Depression Inventory (BDI, BDI-II). We investigated the relationship between 1-year posttransplantation depression and all-cause mortality, acute kidney injury, and serum creatinine 1, 3, and 12 months after transplantation. Furthermore, the association of depression with IL-18 biomarker was recorded 1 year after transplantation. A total of 74 patients (age: 37.06 +/- 16.2 years; 59.5% male) were enrolled in this study 1 year after transplantation. Nineteen (25.6%), 2 (2.7%), and 1 (1.3%) of them experienced mild, moderate, and severe depression, respectively. IL-18 biomarker (independent variable) was significantly associated with depression 1 year after transplantation. Our data suggested that IL-18 level increased significantly in renal transplant patients with depression.
