A 65-year-old male with stable congestive heart failure presents to the clinic. He is currently taking furosemide 80 mg once daily, digoxin 125 mcg once daily, enalapril 20 mg once daily, and ibuprofen 600 mg three times daily (taken for the last month). During his last visit three months ago, his renal function was normal, and his furosemide dose was increased from 40 mg to 80 mg per day. His baseline blood pressure is 125/75, and his current blood pressure is measured at 120/70 mmHg. Upon investigation, his serum sodium is 132 mmol/L (137-144), serum potassium is 5.4 mmol/L (3.5-4.9), serum urea is 18 mmol/L (2.5-7.5), and serum creatinine is 270 µmol/L (60-110). What is the most likely cause of the deterioration in his renal function?

MRCP2-4041

An 80-year-old man presented to his GP complaining of gradual bilateral lower limb swelling over the past month. He also reported experiencing back pain and widespread joint pains. Upon examination, the patient was found to have macroglossia, a pulse of 90 beats per minute, and a blood pressure of 160/95 mmHg. Urinalysis revealed 4+ protein and 1+ blood. Blood tests showed abnormal levels of Hb, creatinine, bicarbonate, and albumin, among others. The patient was referred to a nephrologist who conducted a renal biopsy, which revealed nodular glomerulosclerosis with amorphous hyaline deposits in the glomeruli. Congo red stain was positive. What is the most likely underlying disorder?

MRCP2-4035

A 67-year-old man visits the nephrology outpatient department for his yearly review appointment. He has a medical history of stage IIIb chronic kidney disease and hypertension. He takes amlodipine, ramipril, and doxazosin. He is a non-smoker and non-drinker who lives alone and works as a non-executive director for a multinational company.

During his visit, his vital signs are heart rate 84 beats per minute, blood pressure 156/88 mmHg, respiratory rate 16/minute, oxygen saturation 98% on room air, and temperature 36.7ºC. Physical examination reveals a well-looking man who is clinically euvolemic. Cardio-respiratory and abdominal examinations are unremarkable.

The consultant reviews his recent blood tests, which show Hb 124 g/L, platelets 189* 109/L, WBC 9.2 * 109/L, Na+ 137 mmol/L, K+ 4.2 mmol/L, urea 8.9 mmol/L, creatinine 184 µmol/L, CRP 4 mg/L, adjusted calcium 2.01 mmol/L, phosphate 1.81 mmol/L, albumin 38 g/L, ALP 145 IU/L, and parathyroid hormone 7.6 pg/L.
