Title: The prevalence of micro-albuminuria and glomerular hyperfiltration in young patients with IDDM
Abstract: We have assessed the prevalence of two risk factors for diabetic nephropathy, i.e., micro-albuminuria and a raised glomerular filtration rate (GFR), in 127 insulin-dependent diabetic patients aged 13–36 years. Micro-albuminuria (albumin excretion rate (AER) 20–200 μg/min) was found in 46 subjects (36%) and GFR was elevated (>135 ml/min/1.73 m2) in 43 (34%). The prevalence of supranormal GFR declined and that of micro-albuminuria rose progressively with the increasing duration of diabetes. While age and sex distribution were similar in subjects with and without raised AER, duration of diabetes was significantly longer, blood pressure (BP) was significantly greater and age of onset was lower in the microalbuminuric group. Blood pressure was significantly elevated only in the patients with AFR of 70–200 μg/min; there was a linear trend for BP to rise as AER increased. Stepwise logistic regression analysis indicated that duration of diabetes (P < 0.0001), age of onset of diabetes (P < 0.005) and current glycaemic control. (HbA1) (P < 0.01) were risk factors for micro-albuminuria. The association with a rising blood pressure appears to be secondary to the renal involvement. In this cross-sectional study an association of micro-albuminuria with a raised GFR could not be demonstrated.
