title: Microalbuminuria in relation to metabolic control and blood pressure in adolescents with type 1 diabetes.
abstract: BACKGROUND
  The objective of this study was to assess the frequency of microalbuminuria and the relationship with other risk factors for the development of diabetic nephropathy.
  
  
  METHODS
  Our cross-section study involved a group of 60 adolescence of both sexes, mean age 15.3 ±2.43 years with mean duration of diabetes 7.74 ±3.44 years. Albumin excretion rate was measured on 2-3 samples of the first morning urine in the period below 6 months and persistent microalbuminuria was defined if its increased in two out of three urine specimens. Ambulatory blood pressure was monitored (ABPM, SpaceLabs 90207).
  
  
  RESULTS
  Microalbuminuria developed in 13.3% of adolescents with mostly completed sexual development, statistically significantly poorer metabolic control (9.79% vs. 8.7%) and higher BMI (23.59 kg/m(2) vs. 20.85 kg/m(2)) than in the patients with normoalbuminuria. The mean night-time systolic blood pressure (SBP) was statistically significantly higher in microalbuminuric patients than in normoalbuminurics. The nocturnal dip was reduced in 41.7% of our patients; 38.5% of nondippers were in normoalbuminuric and 62.5% in microalbuminuric patients.
  
  
  CONCLUSIONS
  Diabetic adolescents require particular attention in order to minimize the factors such as high HbA(1c), elevated body mass index and night-time SBP in the development of incipient nephropathy.
