Introduction
The prevalence of chronic kidney disease (CKD) stages 3 to 5, defined as eGFR <60 ml/min/1.73 m2 for more than three months, in the United Kingdom (UK) is 8%. We investigated the incidence of low eGFR and proteinuria in patients attending our large tertiary referral lipid clinic in 2008.
Methods
In 2008, 1,283 patients were seen, of which 1,029 had complete serum lipid and renal profiles. Estimated glomerular filtration rate (eGFR) was calculated for these patients using the 4-variable MDRD formula. The prevalence of low eGFR (eGFR < 60 ml/min/1.73 m2) and proteinuria (albumin/creatinine ratio >2.4 mg/mmol or urinary protein excretion >0.06 g/l) was calculated.
Results
The prevalence of low eGFR and proteinuria was 11.2 and 19.4%, respectively. The percentage of patients with serum lipid levels within the target range suggested by international guidelines was lower among those with low eGFR and proteinuria than in the entire study population, despite similar proportions being treated with statins across all groups.
Conclusions
The prevalences of low eGFR and proteinuria in a group of 1,029 dyslipidaemic patients attending a large tertiary referral lipid clinic were 11.18 and 19.42%, respectively. These levels are much higher than in the general UK population.
