Ten patients, mean age 51.50 +/- 3.03 years, with degenerative rheumatism on NSAID treatment without any sign of renal disease, and 11 control subjects, mean age 43.50 +/- 1.51 years, were studied. NSAID treatment was of 11.30 +/- 5.60 weeks duration in average, with ibuprofen, naproxen, or indomethacin. Urinary excretion of three specific renal tubular enzymes--AAP: alanine-amino-peptidase, GGT: gamma-glutamyl-transpeptidase, and beta-NAG: beta-N-acetyl-glucosaminidase, were determined in 8-h overnight urine samples, as well as GFR creatinine clearance/1.73 m2, urinary volume/8 h, specific gravity of the urine, proteinuria and glucosuria. In the group treated with NSAIDs, urinary excretion of the enzymes was significantly higher than in the control group--AAP: 1414.20 +/- 317.60, 864.20 +/- 94.42, p < 0.00001; GGT: 8034.6 +/- 1378.55, 5095.64 +/- 614.40, p < 0.00001, and beta-NAG: 1644.60 +/- 299.97, 964.82 +/- 142.00, p < 0.00001. Patients on NSAID treatment showed abnormal urinary excretion of AAP in 7/10 cases, of GGT in 6/10, and of beta-NAG in 7/10 cases. Duration of the treatment did not correlate with the urinary excretion of the enzymes. Age was in correlation with the urinary excretion of the enzymes only in the control group, r = 0.52, p < 0.005 for AAP, r = -0.43, p < 0.02 for GGT, and r = -0.23, p < 0.05 for beta-NAG.(ABSTRACT TRUNCATED AT 250 WORDS)

D010003 Osteoarthritis A progressive, degenerative joint disease, the most common form of arthritis, especially in older persons. The disease is thought to result not from the aging process but from biochemical changes and biomechanical stresses affecting articular cartilage. In the foreign literature it is often called osteoarthrosis deformans.

D000894 Anti-Inflammatory Agents, Non-Steroidal Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.
