Thyroid disorders among dialysis patients

Area of Science:

• Nephrology
• Endocrinology
• Internal Medicine

Background:

• Thyroid hormones (TH) are crucial for maintaining human homeostasis, influencing fluid and electrolyte balance.
• The kidney is a primary target for TH actions, with effects ranging from pre-renal influences to direct renal impacts.
• Chronic kidney disease (CKD) significantly alters the delicate balance of TH, particularly in advanced stages.

Purpose of the Study:

• To outline the common thyroid abnormalities observed in patients with chronic kidney disease (CKD).
• To explore the relationship between thyroid dysfunction and the progression of kidney disease.
• To highlight the clinical significance of thyroid alterations in the context of CKD management.

Main Methods:

• Review of existing literature on thyroid function in CKD patients.
• Analysis of reported thyroid abnormalities in patients undergoing dialysis.
• Correlation of thyroid status with clinical parameters in CKD.

Main Results:

• CKD is associated with a high prevalence of subclinical hypothyroidism and low free triiodothyronine (FT3) syndrome.
• Thyroid dysfunction in CKD is linked to systemic complications including micro-inflammation, endothelial damage, and cardiac issues.
• Specific thyroid abnormalities are frequently reported in CKD patients, particularly those on dialysis.

Conclusions:

• Alterations in thyroid hormone levels and metabolism are common in CKD patients.
• These thyroid changes contribute to the pathophysiology and adverse outcomes in CKD, including increased mortality.
• Understanding and addressing thyroid abnormalities is essential for comprehensive CKD care.
