Electrolytes disturbances after kidney transplantation

Area of Science:

• Nephrology
• Transplantation Medicine
• Clinical Chemistry

Background:

• Water and electrolyte disturbances are common complications in renal transplant recipients.
• These abnormalities can arise from various factors, including rejection and immunosuppressive medications.

Purpose of the Study:

• To describe the pathophysiology of prevalent electrolyte and water abnormalities in kidney transplant recipients.
• To outline the treatment strategies for these common post-transplant complications.

Main Methods:

• A literature search was conducted on PubMed using keywords related to kidney transplantation and electrolyte/acid-base disturbances.
• The search combined terms such as 'kidney transplantation' with 'electrolytes', 'sodium', 'potassium', 'phosphate', 'calcium', 'acid-base', and 'disturbances' or 'abnormalities'.

Main Results:

• Tubular dysfunction, caused by rejection or calcineurin inhibitors (CNIs), leads to abnormalities in major electrolytes.
• Common findings include renal tubular acidosis, hyperkalemia (5-40% with CNIs), hypomagnesemia (frequent), phosphate decline post-transplant, and hypercalcemia (often due to hyperparathyroidism).
• Severe magnesium depletion can manifest with neurological and muscular symptoms.

Conclusions:

• Kidney transplant patients exhibit electrolyte abnormalities more often than non-transplant patients with similar renal function.
• A thorough understanding of the pathophysiology and management of these electrolyte imbalances is essential for optimal patient care.
