A 15-year-old boy with a 10-year history of type 1 diabetes mellitus was referred to the adolescent diabetes clinic from the paediatric clinic. Diabetes control had always been satisfactory and his recent haemoglobin A1c concentration was 67 mmol/mol (20-42). He felt generally well, although on a growth chart his weight had fallen steadily from the 50th centile 18 months previously to the 10th centile, and his height had fallen from the 50th centile to the 25th centile.

Investigations:
serum sodium142 mmol/L (137-144)
serum potassium2.7 mmol/L (3.5-4.9)
serum urea4.6 mmol/L (2.5-7.0)
serum creatinine102 umol/L (60-110)
estimated glomerular filtration rate (MDRD)>60 mL/min/1.73 m2 (>60)
plasma renin activity (after 30 min supine)1.0 pmol/mL/h (1.1-2.7)
plasma aldosterone (after 30 min supine)125 pmol/L (135-400)
serum cortisol (09.00 h)190 nmol/L (200-700)

A 64-year-old man was referred to the foot clinic. He had tripped over his cat 1 week previously and had complained of an ache in his left foot since then. He had a 12-year history of type 2 diabetes mellitus and hypertension. He was taking metformin, gliclazide, pioglitazone, bendroflumethiazide, ramipril, simvastatin and aspirin.
On examination, his blood pressure was 154/88 mmHg. Foot examination showed absent vibration perception to his ankle. The dorsalis pedis and posterior tibial pulses were easily palpable on both feet.
Investigations:
serum urea12.6 mmol/L (2.5-7.0) serum creatinine166 umol/L (60-110) haemoglobin A1c79 mmol/mol (20-42)
urinary albumin:creatinine ratio8.7 mg/mmol (<2.5)
