title: Circadian blood pressure variation and antihypertensive medication adjustment in normoalbuminuric type 2 diabetes patients.
abstract: OBJECTIVE
  The aim of the study was to assess the effect of an antihypertensive treatment adjustment on 24-hour blood pressure variation in type 2 diabetes patients.
  
  
  METHODS
  The study group included 59 hypertensive type 2 diabetes patients subjected to a single one-step antihypertensive agent dose adjustment (increase or decrease). Ambulatory blood pressure monitoring was performed at baseline and 4-6 weeks after the treatment modification. Controls were 41 matched patients, in whom antihypertensive treatment remained unchanged.
  
  
  RESULTS
  At baseline, 45 (76%) study group patients and 29 (71%) controls were 'non-dippers'; a similar number of patients in both groups converted to 'dipping' or vice versa: 11 (19%) from the study group and 7 (17%) controls. 'Converters' from the study group were significantly younger (47.5 +/- 3.9 vs. 56.4 +/- 12.2 years; p < 0.05) and had lower 24-hour systolic blood pressure than 'non-converters': 113.7 +/- 7.2 vs. 127.7 +/- 20.3 mm Hg (p < 0.01).
  
  
  CONCLUSIONS
  A single one-step antihypertensive medication adjustment does not affect 'dipping' status in type 2 diabetes patients. However, the assessment of blood pressure variation should be made with greater caution in younger type 2 diabetes subjects with low systolic blood pressure.
