MRCP2-3869

A 25-year-old obese man presents with mild ankle swelling and a urinalysis that shows +++ protein but no blood.

He also has high blood pressure with a reading of 145/90 mmHg. A renal biopsy is scheduled for the following week, and a protein selectivity index of 15% is found in his urine analysis. He is started on prednisolone 60 mg daily as a precaution. Prior to the biopsy, his 24-hour urine collection is repeated and shows a decrease in urine protein output to 1.5 g/24 hours. What is the most likely diagnosis?
