    Abstract:
    Tenascin is a component of the extracellular matrix that responds rapidly to inflammation or injury. The activity index and chronicity index of immunoglobulin A nephropathy are mainly used to decide whether or not steroid therapy is indicated, but are sometimes difficult to evaluate histologically. We investigated whether tenascin staining of the glomeruli was an indicator of the activity or chronicity indices in patients with immunoglobulin A nephropathy. Tenascin staining was evaluated immunohistochemically in 38 renal specimens, including 32 from patients with immunoglobulin A nephropathy and six from control kidneys, and the extent of staining was scored. Tenascin staining was correlated with the chronicity index (r = 0.643, P < 0.0003) but not with the activity index.
