The study is designed as a single-center, prospective, observational research. A total of 50 stable-course chronic hemodialysis patients over 18 years of age and treated for at least 3 months will be included in the study and the study period will be planned for 12 months. 25 of the 50 chronic hemodialysis patients planned to be included in the study will use MCO-membrane and the other 25 will use high-flux membrane. The distribution of patients to the high-flux membrane and MCO membrane groups will be done randomly (sequentially single-pair number method). Then, the standard 12-hour (3x4 hours/week) hemodialysis treatment will continue. At the beginning of the study (0.), at the end of the third (3.) month and at the end of the sixth (6.) month;
Monthly laboratory tests routinely performed on hemodialysis patients (tests routinely performed in hemodialysis patient follow-up) 5 ml blood samples will be taken from the hemodialysis set to determine the levels of medium-large molecule-weight toxins-wastes and inflammatory parameters before and after dialysis, and the sera will be separated and stored at -80oC for use at the end of the study.
Automatic blood pressure measurement will be performed before and after hemodialysis to evaluate arterial stiffness.
The Malnutrition Inflammation Score will be applied to evaluate the nutritional status (the MIS form is given in the appendix) Visual Analog Scale will be used for appetite Visual Analog Scale will be used for uremic pruritus Depression scale screening (Beck's scale)
