BACKGROUND/AIMS: We previously found increased urinary protein excretion, glomerular filtration rate (GFR) and blood pressure in a retrospective analysis of patients with previous nephropathia epidemica (NE). Here, we evaluated the long-term outcome after NE in a prospectively recruited patient group. METHODS: Proteinuria, GFR and ambulatory 24-hour blood pressure were assessed 4-7 years (mean 6) after acute NE in 37 patients, and these values were compared to those from 38 seronegative controls. RESULTS: Six years after NE, the prevalence of elevated urinary alpha(1)-microglobulin excretion was higher in the patients than controls (9/35 vs. 1/38; p = 0.005). The patients also had higher urinary protein excretion (0.17 +/- 0.05 vs. 0.14 +/- 0.04 g/day; p = 0.006), GFR (119 +/- 19 vs. 109 +/- 14 ml/min/1.73 m(2); p = 0.016) and mean systolic (123 +/- 11 vs. 117 +/- 9 mm Hg; p = 0.012), nighttime systolic (109 +/- 11 vs. 100 +/- 9 mm Hg; p = 0.001) and nighttime diastolic blood pressure (70 +/- 7 vs. 66 +/- 7 mm Hg; p = 0.035) than the controls. CONCLUSIONS: These results confirm our previous findings of a higher prevalence of tubular proteinuria and increased urinary protein excretion, GFR and systolic blood pressure 6 years after acute NE.
