[Evaluation of osteodystrophy parameters in a pre-dialysis unit]

Area of Science:

• Nephrology
• Endocrinology
• Biochemistry

Background:

• Advanced Chronic Kidney Disease (ACKD) management is crucial for pre-dialysis patients.
• Osteodystrophy is a common complication in patients with declining renal function.
• Early detection of metabolic bone disease can inform treatment strategies.

Purpose of the Study:

• To analyze osteodystrophy parameters in first-time pre-dialysis patients.
• To investigate correlations between osteodystrophy markers, renal function, and comorbidities.
• To assess the role of ACKD units in early detection of elevated iPTH.

Main Methods:

• Cross-sectional study of 100 pre-dialysis patients.
• Evaluation of age, gender, renal function, serum osteodystrophy parameters (including iPTH, calcium, phosphorous, alkaline phosphatase, CO2), comorbidity index (ICED), and patient origin.
• Statistical analysis to establish correlations between parameters.

Main Results:

• Mean iPTH levels were elevated across all patient origins and significantly higher in men.
• Men exhibited poorer renal function and higher comorbidity scores compared to women.
• Standard serum parameters (calcium, phosphorous, alkaline phosphatase, CO2) did not fully explain the elevated iPTH; nutritional markers (NPNA, albumin) remained adequate.

Conclusions:

• Elevated iPTH can occur in early stages of End-Stage Renal Disease (ESRD) before dialysis initiation.
• Men with ACKD present with higher iPTH, worse renal function, and greater comorbidity.
• ACKD units are vital for the early identification and management of elevated iPTH and related osteodystrophy.
