Question 1

In the immediate post-kidney transplant period (0–4 weeks), which nutritional concern is the HIGHEST priority due to high-dose corticosteroid immunosuppression?

Accepted Answer

High protein catabolism from corticosteroids requiring protein intake of 1.3–2.0 g/kg IBW/day

Answer

High-dose corticosteroids (prednisolone, methylprednisolone) in the early post-transplant period cause significant muscle protein catabolism. KDOQI recommends 1.3–2.0 g/kg IBW/day protein to prevent steroid-induced muscle wasting during this acute period.

Question 2

Post-kidney transplant patients on calcineurin inhibitors (tacrolimus, cyclosporine) must avoid which specific food/drink due to potentially dangerous drug interactions?

Accepted Answer

Grapefruit and grapefruit juice

Answer

Grapefruit and grapefruit juice contain furanocoumarins that inhibit intestinal CYP3A4 enzyme, which metabolizes calcineurin inhibitors. Inhibiting CYP3A4 increases drug bioavailability and blood levels, risking nephrotoxicity and immunosuppression toxicity.

Question 3

Post-transplant weight gain and new-onset diabetes mellitus after transplantation (NODAT) are common nutritional complications. Which dietary pattern is MOST recommended to address both complications?

Accepted Answer

Moderate-calorie diet emphasizing low glycemic index foods, lean proteins, complex carbohydrates, and healthy fats — similar to Mediterranean or DASH pattern — combined with physical activity

Answer

A balanced diet with low glycemic index carbohydrates, lean protein, and healthy fats (Mediterranean/DASH-like) effectively manages both post-transplant weight gain and NODAT by minimizing glycemic excursions, reducing cardiovascular risk, and maintaining lean body mass.

Question 4

A kidney transplant patient develops new-onset hypertension and hyperlipidemia at 6 months post-transplant. Aside from antihypertensive medications, which dietary intervention has evidence for improving both conditions?

Accepted Answer

Mediterranean-style diet with olive oil, fish, legumes, vegetables, and reduced sodium (< 2.3 g/day)

Answer

The Mediterranean diet reduces blood pressure (via sodium/potassium balance, anti-inflammatory polyphenols) and improves lipid profiles (olive oil reduces LDL, increases HDL; omega-3 from fish reduces triglycerides) — both validated benefits in transplant patients.

Question 5

Long-term kidney transplant recipients (>5 years) who have declining graft function (GFR 30–45 mL/min) should be managed nutritionally how?

Accepted Answer

Transition back toward CKD Stage 3b nutrition guidelines: moderate protein restriction (0.6–0.8 g/kg/day), phosphorus and potassium management, sodium restriction, and preparation for potential return to dialysis

Answer

Declining transplant graft function recapitulates CKD pathophysiology. At GFR 30–45 mL/min (CKD Stage 3b), renal dietitian guidelines parallel native CKD Stage 3b: protein moderation (0.6–0.8 g/kg/day), electrolyte monitoring, and preparation for potential renal replacement therapy.
