title: Antithrombin III in mesangial IgA nephritis.
abstract: Plasma Antithrombin III (A T III) was measured in 97 patients with IgA nephritis, 30 patients with non IgA idiopathic mesangial proliferative glomerulonephritis and 40 healthy subjects. The mean plasma A T III levels in the patients with IgA nephritis (105 +/- 10%) was significantly higher than those of normal controls (96 +/- 5%) (p less than 0.0005). The mean plasma A T III levels in the patients with non IgA nephritis (101 +/- 10%) was not different from those of the normal controls or the patients with IgA nephritis. A T III levels were significantly correlated with proteinuria (p less than 0.0001), segmental sclerosis (p less than 0.001), crescents (p less than 0.01), medial hypertrophy (p less than 0.001) and intensity of IgA staining on IMF (p less than 0.02). Patients with IgA nephritis with raised A T III levels had significantly more proteinuria (p less than 0.003), more segmental sclerosis (p less than 0.007) as well as a greater intensity of IgA staining on IMF (p less than 0.02) when compared to patients with normal A T III levels. The data suggest that raised plasma A T III levels may serve as a prognostic marker in IgA nephritis.
