Question 3

A 30-year-old woman who underwent a live related renal transplant for end-stage renal failure secondary to chronic pyelonephritis 4 months ago, now attends the clinic for routine follow up. She is taking tacrolimus and mycophenolate mofetil (MMF). Her urea and electrolytes are: Na+ 136 mmol/L, K+ 3.7 mmol/L, Urea 7.2 mmol/L, Creatinine 146 μmol/L. She was last seen in clinic 2 weeks previously when her urea was 4.2 mmol/l and creatinine 98 μmol/l. She is clinically well and asymptomatic. On examination she was apyrexial and normotensive. Her transplant site was non-tender with no swelling and there were no other signs to be found. Which initial investigations should be performed first?
Your Answer: Doppler ultrasound scan of the transplant site
Correct Answer: Urine and blood cultures
Explanation:After renal transplant, asymptomatic patients can still have graft dysfunction as an early complication, with rising serum creatinine; therefore, urine and blood cultures should be ordered first. This should be followed by measuring the Tacrolimus levels, as this drug can be directly nephrotoxic. Next, a Doppler ultrasound of the transplant site should be ordered, to check for any obstructions or occlusions.

A 65-year-old gentleman with a history of chronic renal failure due to diabetes comes to the clinic for review. He has reported increasing bone and muscle aches over the past few weeks. Medications include ramipril, amlodipine and indapamide for blood pressure control, atorvastatin for lipid management, and insulin for control of his blood sugar. On examination his BP is 148/80 mmHg, his pulse is 79 and regular. His BMI is 28. Investigations show: Haemoglobin 10.7 g/dl (13.5-17.7) White cell count 8.2 x 10(9)/l (4-11) Platelets 202 x 10(9)/l (150-400) Serum sodium 140 mmol/l (135-146) Serum potassium 5.0 mmol/l (3.5-5) Creatinine 192 μmol/l (79-118) Calcium 2.18 mmol/l (2.2-2.67) Phosphate 1.9 mmol/l (0.7-1.5) He has tried following a low phosphate diet. Which of the following would be the next most appropriate step in controlling his phosphate levels?
Your Answer:
Correct Answer: Sevelamer
Explanation:Sevelamer is a phosphate-binding drug that can lower raised serum phosphate levels in chronic kidney disease. Because of its aluminium-related side-effects, aluminium hydroxide is no longer the drug of choice.
The other options are calcium-containing salts that may increase risks of tissue calcification. -

What is the most likely composition of his renal stones?
Your Answer:
Correct Answer: Uric acid stones
Explanation:Uric acid stones will most likely be found in this case because of the patient’s long history of gout. Additionally, studies have shown that ileostomy patients have an increased risk for the development of uric acid stones.

Question 9

A 25-year-old gentleman presents to the hospital feeling unwell and breathless. History reveals that he has chronic renal failure, for which he receives haemodialysis three times per week. Since one week prior to consultation, he has been on vacation and has missed two dialysis sessions. Examination reveals pulmonary oedema. His ECG shows no P waves, broad QRS complexes and peaked T waves. What should you do?
Your Answer:
Correct Answer: Give 10 ml of 10% calcium gluconate intravenously
Explanation:The patient is most likely complaining of the effects of hyperkalaemia, due to missing his dialysis sessions. Additionally, because the patient presents with a risk of cardiac arrest (based on pulmonary oedema and ECG findings), the best intervention is to give calcium gluconate that will address the hyperkalaemia as well as improve the cardiac condition.

A 63-year-old woman visits the diabetes clinic for review. She has had type-2 diabetes for 9 years and is now on insulin therapy. She has diabetic nephropathy, as exemplified by hypertension and proteinuria (urinary PCR 155); a recent creatinine level was 205 μmol/l and eGFR 24 ml/min. Which of the following options best fits her prognosis or management?
Your Answer:
Correct Answer: Treatment with ARB or ACE-I may slow further deterioration in renal function
Explanation:Treatment with ARB or ACE-I may slow further deterioration in renal function in this patient, as studies have shown that blocking of the RAS in type 2 diabetic patients improve renal function.
