Thyroid Function Trends in Dialysis: Unveiling Peritoneal and Hemodialysis Disparities

Area of Science:

• Nephrology
• Endocrinology
• Internal Medicine

Background:

• The relationship between dialysis methods, residual kidney function (RKF), and thyroid function is not well-established.
• Limited prospective research exists comparing thyroid function in peritoneal dialysis (PD) versus hemodialysis (HD) patients.

Purpose of the Study:

• To prospectively assess and compare thyroid function in PD patients versus HD patients over 24 months.
• To investigate the association between thyroid hormone levels and residual kidney function in PD patients.

Main Methods:

• A prospective single-center study involving 18 PD patients and 24 HD patients over 24 months.
• Thyroid function tests (TSH, T3, T4, FT3, FT4) were monitored.
• Comparison of thyroid function parameters between PD and HD groups.

Main Results:

• PD patients exhibited higher baseline T4 and FT3 levels compared to HD patients.
• PD patients showed significantly higher FT4 levels at 12 and 24 months.
• A positive association was found between T4 levels and 24-hour diuresis in PD patients after 12 months.

Conclusions:

• PD patients demonstrate distinct thyroid hormone profiles compared to HD patients.
• Thyroid function evaluation is essential for optimizing care in dialysis patients.
• Further research is needed to understand the implications for RKF and cardiovascular health.
