title: Ambulatory blood pressure in type I diabetes mellitus. Comparison to presence of incipient nephropathy in adolescents and young adults.
abstract: AMBP measurements were obtained at 20-min intervals during the day and at 60-min intervals during the night in 38 adolescents and young adults (12-25 yr old) with type I diabetes, and in 36 healthy, nondiabetic control subjects of comparable age. The group of patients with elevated AER (greater than 15 micrograms/min) had higher mean 24-h sBP, dBP, and BPB (defined as the prevalence of systolic readings greater than 130 mm Hg or diastolic readings greater than 85 mm Hg) compared with both the group of patients with type I diabetes and AER less than 15, and the control group. The normal diurnal variation in BP and BPB was observed in the control group and the group with type I diabetes and AER less than 15, whereas the nocturnal decrease observed in the group with type I diabetes and AER greater than 15 was not statistically significant. Elevations in AMBP of the patient group with AER greater than 15 were reflected in random BP measurements. Even though the mean random BP measurements of all groups were within the normal range for age, the mean random sBP and dBP of the type I diabetes patients with AER greater than 15 was higher than both the control group and the group with type I diabetes and AER less than 15. The GFR, determined by the clearance of 99Tc-DTPA, was associated negatively with measures of AMBP and AER in the group with AER greater than 15.(ABSTRACT TRUNCATED AT 250 WORDS)
