[Long-term treatment of glomerulonephritis with indomethacin with special regard to quantity and selectivity of proteinuria].

In 53 patients (19 women, 34 men), of them 41 patients with an intracapillary proliferative glomerulonephritis, 9 with membranous proliferative and 3 with a membranous glomerulonephritis under an indometacin therapy examinations concerning proteinuria were carried out, partly with determination of the index of selectivity and representation of the protein clearance. In patients with a moderate proteinuria of less than 3 g a day this treatment achieved a smaller antiproteinurie effect than in patients with a large proteinuria. When a large activity of the inflammatory process was present a therapeutic success was less frequently to be proved. An unequivocal correlation between the histological course of the disease and the change of the proteinuria could not be recognized. After cautious estimation of the findings the selectivity of the proteinuria may be regarded as a certain indicator for the application of indometacin. The protein clearance, however, proved less suitable for the judgment of the treatment performed.
