Electrolyte and Acid-Base Abnormalities After Kidney Transplantation

Area of Science:

• Nephrology
• Transplantation Medicine
• Internal Medicine

Background:

• Kidney transplantation is the preferred treatment for end-stage kidney disease, with over 25,500 procedures in the US in 2022.
• Post-transplant patients experience distinct electrolyte and acid-base disturbances compared to those with chronic kidney disease.
• Factors influencing these abnormalities include allograft function, immunosuppressive drugs, and metabolic shifts.

Purpose of the Study:

• To comprehensively review common electrolyte and acid-base disorders after kidney transplantation.
• To highlight the differences between pre- and post-transplant electrolyte profiles.
• To discuss the contributing factors to these post-transplant complications.

Main Methods:

• Literature review of post-transplant electrolyte and acid-base abnormalities.
• Analysis of factors influencing electrolyte balance in kidney transplant recipients.
• Synthesis of current understanding of common post-transplant complications.

Main Results:

• Common abnormalities include hypomagnesemia, hyperkalemia, metabolic acidosis, hypercalcemia, and hypophosphatemia.
• Allograft function significantly impacts electrolyte homeostasis.
• Immunosuppressive medications play a key role in causing these imbalances.

Conclusions:

• Electrolyte and acid-base abnormalities are frequent and distinct in kidney transplant recipients.
• Management requires careful consideration of allograft function and immunosuppressive regimens.
• Further research into optimizing electrolyte balance post-transplant is warranted.
