Abstract

Objective: To evaluate putative risk factors for the development of incipient diabetic nephropathy (persistent microalbuminuria) and overt diabetic nephropathy (persistent macroalbuminuria) in patients with non-insulin dependent diabetes. Design: Prospective, observational study of a cohort of white, non-insulin dependent diabetic patients followed for a median period of 5.8 years. Setting: Outpatient clinic in tertiary referral centre. Subjects: 191 patients aged under 66 years with non-insulin dependent diabetes and normoalbuminuria (urinary albumin excretion rate<30 mg/24 h) who attended the clinic during 1987. Main outcome measures: Incipient and overt diabetic nephropathy. Results: Fifteen patients were lost to follow up. Thirty six of the 176 remaining developed persistent microalbuminuria (30-299 mg/24 h in two out of three consecutive 24 hour urine collections) and five developed persistent macroalbuminuria (≥300 mg/24 h in two out of three consecutive collections) during follow up. The five year cumulative incidence of incipient diabetic nephropathy was 23% (95% confidence interval 17% to 30%). Cox's multiple stepwise regression analysis revealed the following risk factors for the development of incipient or overt diabetic nephropathy: increased baseline log urinary albumin excretion rate (relative risk 11.1 (3.4 to 35.9); P<0.0001); male sex (2.6 (1.2 to 5.4); P<0.02); presence of retinopathy (2.4 (1.3 to 4.7); P<0.01); increased serum cholesterol concentration (1.4 (1.1 to 1.7); P<0.01); haemoglobin A 1c concentration (1.2 (1.0 to 1.4); P<0.05); and age (1.07 (1.02 to 1.12); P<0.01). Known duration of diabetes, body mass index, arterial blood pressure, serum creatinine concentration, pre-existing coronary heart disease, and history of smoking were not risk factors. Conclusion: Several potentially modifiable risk factors predict the development of incipient and overt diabetic nephropathy in normoalbuminuric patients with non-insulin dependent diabetes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
