title: [Microalbuminuria in diabetic and hypertensive patients: a study of 979 patients].
abstract: OBJECTIVE
  Microalbuminuria is a known complication of diabetes mellitus but it is also a cardiovascular risk factor commonly present among hypertensive (non diabetic) population. The prevalence of microalbuminuria is variable and it has been never estimated in our region. The aim of this study has been to determine the prevalence of microalbuminuria in hypertensive (non diabetic) and diabetic population in Extremadura (Spain).
  
  
  METHODS
  The study included diabetic patients and non-diabetic hypertensive ones randomly selected. Microalbuminuria was measured in every patient using albumin/creatinin reactive stick in fasting first morning urine. Whenever possible microalbuminuria was confirmed in laboratory by microalbuminuria/creatinina coefficient in first morning urine samples.
  
  
  RESULTS
  A total of 979 patients (mean age [SD], 67.9 [10.8] years; 409 men and 570 women, 505 diabetics) were studied. The presence of microalbuminuria was found in 12.4% of hypertensive patients and in 21.4% of diabetic patients (p < 0.001). Hypertensives and normotensive diabetics showed a similar prevalence of microalbuminuria (13.3%, not significant), but it tripled in hypertensive diabetics (33.8; p < 0.01). Glicemic control was not different for microalbuminuric diabetic patients and non microalbuminuric ones. The patients receiving rennin-angiotensin axis blocking drugs do not showed less prevalence of microalbuminuria (hypertensives 10.5%, diabetics 23.5%). Microalbuminuria was confirmed in 65.4% of patients.
  
  
  CONCLUSIONS
  The prevalence of microalbuminuria in Extremadura seems to be high either in diabetics or non diabetic hypertensive patients. The finding of microalbuminuria in diabetics patients correlates with hypertension but do not with glicemic control. The prevalence of microalbuminuria is high in spite of using rennin-angiotensin axis blocking drugs.
