title: The influence of long term hydrochlorothiazide administration on the relationship between renin-angiotensin-aldosterone system activity and plasma glucose in patients with hypertension.
abstract: OBJECTIVE
  To observe the relationship between changes in renin-angiotensin-aldosterone system (RAAS) activity and blood plasma glucose after administration of hydrochlorothiazide (HCTZ) for one year in patients with hypertension.
  
  
  METHODS
  108 hypertensive patients were given 12.5 mg HCTZ per day for one year. RAAS activity, plasma glucose levels, and other biochemical parameters, as well as plasma oxidized low density lipoprotein (oxLDL) levels, were measured and analyzed at baseline, six weeks, and one year after treatment.
  
  
  RESULTS
  After one year of treatment, the reduction in plasma glucose observed between the elevated plasma renin activity (PRA) group (-0.26 ± 0.26 mmol/L) and the nonelevated PRA group (-1.36 ± 0.23 mmol/L) was statistically significant (P < 0.05). The decrease of plasma glucose in the elevated Ang II group (-0.17 ± 0.18 mmol/L) compared to the nonelevated Ang II group (-1.07 ± 0.21 mmol/L) was statistically significant (P < 0.05). The proportion of patients with elevated plasma glucose in the elevated Ang II group (40.5%) was significantly higher than those in the nonelevated Ang II group (16.3%) (P < 0.05). The relative oxLDL level was not affected by the treatment.
  
  
  CONCLUSIONS
  Changes in RAAS activity were correlated with changes in plasma glucose levels after one year of HCTZ therapy.
