Abstract

The aim of this study was to evaluate the circadian blood pressure variations in subjects with or without microalbuminuria (Urinary Albumin Excretion (UAE) between 30 and 300 mg/24 h. Forty-nine non-insulin dependent diabetic subjects with essential arterial hypertension and without proteinuria (UAE < 300 mg/24 h) were consecutively recruited. Systolic (SBP) and Diastolic Blood Pressure (DBP) have been measured using a SpaceLabs 90207 ambulatory blood pressure monitor, every 15 minutes during daytime (7:00 a.m. to 22:00 p.m.) and every 30 minutes during nighttime (22:00 p.m. 7:00 a.m.). UAE has been measured by nephelometry on three 24 h urine collections. The group with microalbuminuria (n = 16) was not different from the group with normoalbuminuria (n = 33) for age, sex ratio, body mass index, known diabetes duration, proportion of anti-hypertensive treatment, serum creatinine and HbA1c. Daytime blood pressures (SBP/DBP: 144 +/- 15/83 +/- 8 vs 137 +/- 13/84 +/- 9 mmHg) and nighttime DBP (75 +/- 7 vs 74 +/- 9 mmHg) were comparable between both groups. In contrast, the nighttime SBP was higher in subjects with microalbuminuria than in those without (139 +/- 17 vs 129 +/- 17 mmHg; p = 0.016). If dippers are the subjects with a n...Continue Reading

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.
