Abstract
BACKGROUND: Albuminuria is an early marker of kidney disease in patients with diabetes and/or hypertension undetected or untreated albuminuria is a leading cause of chronic kidney disease and cardiovascular events, The purpose of the present survey was to assess the prevalence of albuminuria in patients with diabetes and hypertension, treated with a combinations of renin angiotensin aldosterone system inhibitors and dihydropyridine calcium channel blockers. METHODS: The survey was performed in 105 Primary Care Units in Turkey and involved outpatients, routinely visited by either a specialist or a non-specialist physician. Albuminuria was evaluated in a spot morning urine sample, as albumin-creatinine ratio, using the Multistic-Clinitek-device analyzer (Siemens), that has a strong correlation with 24-h urinary albumin excretion. Microalbuminuria was defined as a loss of 3.4-33.9mg albumin/mmol creatinine and macroalbuminuria as a loss of >33.9mg albumin/mmol creatinine. Diabetes was assessed through documented blood glucose concentration or use antidiabetic drugs, whereas hypertension through blood pressure measurement and current antihypertensive treatment. RESULTS: The survey enrolled 1708 subjects with a prevalence of type 2 diabetes (87.6%). Albuminuria was detected in 52.0% of patients. Blood pressure was controlled in 37.0% and diabetes in 56.7%. The risk of albuminuria was significantly high in patients with uncontrolled diabetes (p<0.001) and blood pressure (p=0.009). CONCLUSIONS: In a large cohort of treated hypertensive patients with diabetes, albuminuria was present in about 50% and was correlated with poor diabetes and blood pressure control. Systematic screening of albuminuria, particularly in Primary Care, is an important tool for the early diagnosis of nephropathy.
