α-klotho and anemia in patients with chronic kidney disease patients: A new perspective

Area of Science:

• Nephrology
• Hematology
• Endocrinology

Background:

• Anemia is a frequent complication of chronic kidney disease (CKD), leading to adverse cardiovascular outcomes.
• Symptoms like left ventricular hypertrophy and heart failure in CKD patients are often linked to anemia, not solely the kidney disease itself.
• The α-klotho (KL) protein, primarily found in kidneys, is implicated in the development of anemia in CKD.

Purpose of the Study:

• To review current evidence on the potential role of α-klotho (KL) in the context of renal anemia.
• To explore the relationship between KL expression levels and anemia in patients with CKD.
• To identify potential therapeutic implications of understanding KL’s function in renal anemia.

Main Methods:

• Literature review of existing studies on α-klotho (KL) and renal anemia.
• Analysis of evidence linking KL expression to anemia occurrence in chronic kidney disease (CKD).
• Synthesis of findings regarding KL’s hypothesized compensatory role in CKD-related anemia.

Main Results:

• Low expression of α-klotho (KL) appears to be associated with improved anemia in patients with chronic kidney disease (CKD).
• This observation suggests that reduced KL expression might be a compensatory mechanism against anemia's effects in CKD.
• The review consolidates evidence pointing towards KL’s significant involvement in renal anemia.

Conclusions:

• Understanding the role of α-klotho (KL) in renal anemia is crucial for managing chronic kidney disease (CKD).
• Further research into KL’s function may unveil novel therapeutic targets for treating anemia in CKD patients.
• Targeting KL pathways could represent a future strategy for improving outcomes in CKD with anemia.
