Analysis of factors influencing vascular calcification in peritoneal dialysis patients and their impact on long-term...

Area of Science:

• Nephrology
• Cardiovascular Research
• Clinical Medicine

Background:

• Vascular calcification is a common complication in patients undergoing peritoneal dialysis (PD).
• Identifying factors contributing to vascular calcification and its impact on prognosis is crucial for patient management.

Purpose of the Study:

• To investigate the influencing factors of vascular calcification in PD patients.
• To explore the relationship between vascular calcification and long-term prognosis in PD patients.

Main Methods:

• Retrospective cohort study of 91 chronic kidney disease patients on PD.
• Collected demographic and clinical data, including serum sclerostin (SOST), calcium, phosphate, albumin, and intact parathyroid hormone.
• Assessed abdominal aortic calcification (AAC) via X-ray, dividing patients into AAC and Non-AAC groups.

Main Results:

• Vascular calcification risk factors identified: longer dialysis time, diabetes, hypertension, and SOST.
• Patients with AAC were older and had longer dialysis times.
• AAC group showed significantly higher all-cause mortality (P < 0.001).

Conclusions:

• Longer dialysis time, diabetes, hypertension, and SOST are significant risk factors for vascular calcification in PD patients.
• Abdominal aortic calcification, prolonged dialysis, and diabetes are associated with increased mortality risk in PD patients.
