Kidney Transplant Nutrition Flashcards

What is the MOST common cause of death in long-term kidney transplant recipients (beyond 1 year post-transplant)?

Answer: Cardiovascular disease (myocardial infarction, stroke)

Cardiovascular disease (MI, stroke, congestive heart failure) is the leading cause of death in kidney transplant recipients beyond 1 year, accounting for 30–40% of deaths. Pre-existing CVD risk, post-transplant hypertension, dyslipidemia, NODAT, and obesity compound this risk.

A transplant patient asks about eating sushi and raw seafood. How should the transplant dietitian respond based on food safety guidelines for immunocompromised individuals?

Answer: Raw or undercooked seafood should be avoided due to elevated risk of serious foodborne illness (Vibrio, Listeria, Salmonella) in immunocompromised patients; fully cooked fish and seafood are safe

Immunosuppression (calcineurin inhibitors, mycophenolate) significantly impairs innate and adaptive immunity, making foodborne pathogens life-threatening. Raw/undercooked seafood carries Vibrio, Listeria, Salmonella, and hepatitis A risks — all should be avoided permanently while on immunosuppression.

A kidney transplant recipient develops hyperuricemia and gout 2 years post-transplant while on cyclosporine. What dietary modification is MOST helpful for managing this condition?

Answer: Limit high-purine foods (organ meats, shellfish, red meat), avoid alcohol (especially beer/spirits), increase hydration, and limit high-fructose corn syrup — particularly while cyclosporine causes renal uric acid retention

Cyclosporine reduces renal uric acid excretion, causing hyperuricemia and gout in 50–80% of cyclosporine-treated transplant recipients. Dietary management targets high-purine foods (organ meats, shellfish), alcohol (elevates urate and reduces excretion), and high-fructose corn syrup (promotes endogenous uric acid production).

A kidney transplant recipient is found to have BK virus nephropathy 18 months post-transplant. To fight the infection, immunosuppression is reduced. How does this affect nutritional management?

Answer: Maintain or increase protein intake (1.0–1.3 g/kg/day) to support immune function and potential rejection risk; monitor for recurrence of CKD-related dietary restrictions if GFR declines

BK virus nephropathy requires reduction of immunosuppression to allow immune clearance of the virus, but this increases rejection risk. Nutritional support targets immune function recovery (adequate protein, zinc, vitamins) while monitoring graft function (GFR trends) for dietary adjustments.

In a pre-transplant evaluation, a patient with morbid obesity (BMI 42 kg/m²) is being assessed for kidney transplant candidacy. What is the typical BMI threshold above which many transplant centers require weight loss before listing?

Answer: BMI > 35–40 kg/m², with most centers requiring BMI < 35–40 as a transplant criterion

Most transplant centers use BMI > 35–40 kg/m² as a threshold for requiring weight loss before transplant listing because obesity significantly increases perioperative complications (wound infections, delayed graft function, thrombosis) and post-transplant NODAT, cardiovascular risk, and mortality.

Which micronutrient deficiency is MOST commonly found in kidney transplant recipients and is important for wound healing, immune function, and prevention of transplant-related malignancies?

Answer: Vitamin D (25-hydroxyvitamin D)

Vitamin D deficiency is highly prevalent in kidney transplant recipients (50–90%), caused by persistent impaired hydroxylation post-transplant, sun avoidance (skin cancer risk with immunosuppression), and pre-existing CKD-related deficiency. It affects immune function, bone health, and may influence transplant outcomes and malignancy risk.
