Objectives of this study were to determine the prevalence of microalbuminuria and the level of glycaemic control obtained in a young Italian population-based cohort of subjects with short duration of insulin-dependent diabetes mellitus (IDDM). Out of 298 subjects with onset of IDDM in the period 1984-88, 211 were examined (71%) in 1991-92 (duration of disease 3-9 years). Microalbuminuria was defined as albumin excretion rate (AER) 20-200 micrograms min-1 in an overnight urine collection or alb/creat > 2.5 mg mmol-1 in men and > 4.5 mg mmol-1 in women in one first morning urine sample. Twelve subjects had AER 20-200 micrograms min-1 and 4 had elevated alb/creat ratio. Prevalence of microalbuminuria was 7% (95% Cl 4.0-11.1) in subjects with duration of IDDM 3-9 years and 4% (0.3-7.7) in subjects with duration 3-5 years. Only 1 microalbuminuric subject was found out of 52 aged < or = 14 years. Duration of IDDM was significantly higher (6.9 +/- 1.9 years vs 5.7 +/- 1.6, p = 0.007) and HDL-cholesterol lower (1.22 +/- 0.21 mM vs 1.42 +/- 0.34, p = 0.025) in micro- than in normoalbuminuric subjects, even after adjustment for age, systolic and diastolic blood pressure, BMI, and HbA1c. In almost 50% of the cohort, HbA1c levels were over 9%, whereas only in 10.9% HbA1c levels were lower than 6.6% (mean +3 SD). In conclusion, this Italian population-based study showed low prevalence of microalbuminuria in young subjects with short duration of IDDM, even if the glycaemic control obtained was far from ideal.

Abstract

Objectives of this study were to determine the prevalence of microalbuminuria and the level of glycaemic control obtained in a young Italian population-based cohort of subjects with short duration of insulin-dependent diabetes mellitus (IDDM). Out of 298 subjects with onset of IDDM in the period 1984-88, 211 were examined (71%) in 1991-92 (duration of disease 3-9 years). Microalbuminuria was defined as albumin excretion rate (AER) 20-200 micrograms min-1 in an overnight urine collection or alb/creat > 2.5 mg mmol-1 in men and > 4.5 mg mmol-1 in women in one first morning urine sample. Twelve subjects had AER 20-200 micrograms min-1 and 4 had elevated alb/creat ratio. Prevalence of microalbuminuria was 7% (95% Cl 4.0-11.1) in subjects with duration of IDDM 3-9 years and 4% (0.3-7.7) in subjects with duration 3-5 years. Only 1 microalbuminuric subject was found out of 52 aged < or = 14 years. Duration of IDDM was significantly higher (6.9 +/- 1.9 years vs 5.7 +/- 1.6, p = 0.007) and HDL-cholesterol lower (1.22 +/- 0.21 mM vs 1.42 +/- 0.34, p = 0.025) in micro- than in normoalbuminuric subjects, even after adjustment for age, systolic and diastolic blood pressure, BMI, and HbA1c. In almost 50% of the cohort, HbA1c levels were over 9%, whereas only in 10.9% HbA1c levels were lower than 6.6% (mean +3 SD). In conclusion, this Italian population-based study showed low prevalence of microalbuminuria in young subjects with short duration of IDDM, even if the glycaemic control obtained was far from ideal.
