Moderately increased albuminuria unmasked hypertension.

The normal rate of albumin excretion is less than 30 mg/day (20 µg/min); persistent albumin excretion between 30 and 300 mg/day (20-200 µg/min) is called moderately increased albuminuria (formerly called microalbuminuria). In addition to being associated with diabetic nephropathy, moderately increased albuminuria has also been associated with cardiovascular disease in patients with as well as without diabetes. We present a case report of a man with moderately increased albuminuria who developed hypertension only detected by an ambulatory blood pressure monitoring procedure.
