[Frequency of chronic kidney disease among ambulatory patients with type 2 diabetes]

Type 2 diabetes mellitus is the main cause of chronic kidney disease in developed countries.

To study the prevalence of chronic kidney disease among adults with diabetes mellitus attended at a public primary health care clinic in southern Chile.

One hundred patients with type 2 diabetes mellitus, aged more than 15 years participated in this cross sectional study. Chronic kidney disease was defined as the presence of a urine albumin/creatinine ratio over 30 mg/g or an estimated glomerular filtration rate of less than 60 mL/min/1,73 m², detected in at least two opportunities, separated at least by three months.

Thirty four percent of participants had chronic kidney disease (17% stage 1 or 2 and 17% stage 3). Thirty percent of participants had an abnormal urinary albumin/creatinine ratio. Halfof the patients with an estimated glomerular filtration rate below 60 mL/min/1,73 m², had a normal urinary albumin/creatinine ratio.

The rates of chronic kidney disease in this group of diabetic patients are very similar to those reported elsewhere.
