title: Treatment of hypertension in chronic kidney disease patients under specialized care: one-center cross-sectional analyses.
abstract: OBJECTIVE
  The study analyzed hypertension management and control rates among non-dialysis, non-transplanted hypertensive chronic kidney disease (CKD) patients under specialized care in Gdansk nephrology center in 1996-2011.
  
  
  METHODS
  It was a retrospective, cross-sectional study analyzing data from medical records of 190, 490, 1799 and 1696 subjects with CKD, who received outpatient care in 1996, 2001, 2006 and 2011, and were included in four independent surveys, respectively.
  
  
  RESULTS
  The average number of antihypertensive drugs per patient increased significantly (p < 0.01) as follows 1.74 ± 0.9 (1996), 2.08 ± 1.01 (2011), 2.5 ± 1.19 (2006) and 2.65 ± 1.18 (2011). The percentage of patients receiving diuretics, beta-blockers and drugs inhibiting renin-angiotensin-aldosterone increased significantly in subsequent years, while a frequency of therapy with calcium channel blockers decreased (p < 0.001). 16%, 30%, 42% and 54% of subjects had causal BP values < 140/90 mmHg (p < 0.001). When specific thresholds for CKD patients according to JNC recommendations were used, the control rate was worse but also showed significant improvement in the second, third and final surveys, i.e. 9%, 12%, 14% and 24% (p < 0.001). The subgroup analysis revealed that a better control rate was observed in following groups: < 65 years old; I-II stage of CKD; primary glomerulonephritis; without cardiovascular complications or diabetes.
  
  
  CONCLUSIONS
  The study may show an improvement in the effectiveness of antihypertensive treatment in CKD patients under specialized care in Gdansk Nephrology Centre in 1996-2011.
