The aim of the project is to assess the effect of functioning AVF in renal transplant patients on fibrosis, inflammation and LVH indicators. Clinical and laboratory parameters will be compared in a group of 150 patients, 75 patients with a functioning fistula and 75 patients with inactive vascular access. We will assess the impact of functional AVF and the levels of biomarkers on the survival of patients and transplanted kidneys.
Patients after kidney transplantation during a routine visit will be asked to participate to the study. In eligible a number of studies will be conducted: * detailed clinical examination * routine laboratory tests * lung ultrasound * muscle strength with a dynamometer * ultrasound assessment of upper limb vessels with assessment of fistula function (in the case of active fistula) and for the possibility of future vascular access * blood collection and protection (10-15 ml) for biomarkers * survey EQ-5D-5L and LVD-36 * functional strength test. The obtained clinical data and test results will be subject to statistical analysis after anonymization. The impact of individual parameters on long-term prognosis will be assessed.

RECRUITINGQuality of life with EQ-5D-5L
The survey results will be compared between the study and control groups to see if the presence of the arteriovenous fistula affects quality of life.
Time frame: Baseline visit up to 12 months
Prognostic value of biomarkers (NT-proBNP, Il-6, sST2, galectin-3, GDF-15, MMP7, TIMP1)
The levels of biomarkers will be measured and the results will be compared between the study and control groups. A prognostic value of the biomarkers will be estimated.
Time frame: Baseline visit and up to 12 months
Hospitalization-free survival
Hospital-free survival will be reported as the number of patients living 12 months after the initial visit without the need for hospitalization.
Time frame: Up to 12 months from baseline visit
