Primary IgA nephropathy: a preliminary report.

ABSTRACT

A total of 106 renal biopsies were examined. Each biopsy was processed for routine paraffin sectioning and frozen sectioning. Direct immunofluorescence was done by the conventional method. The immunofluorescence patterns were correlated with histopathological changes and clinical presentation. Fourteen biopsies revealed weak to strong IgA staining and out of these, 11 seemed to fulfil the criteria of primary IgA nephropathy. These cases were diagnosed in a brief period of eleven months and there had not been any earlier published series from India.
