In order to elucidate the biochemical anti-inflammatory properties of naproxen, the effects of this compound on activities of mucopolysaccharase [beta-glucuronidase (beta-Gase) and lysozyme (LZ)], acid protease (APase) and collagenolytic enzyme (CL) in inflamed tissues were investigated by means of a proliferative inflammatory model in filter-paper-implanted rats. In the preventive test, naproxen strongly inhibited granuloma formation and exudate accumulation as did indomethacin and prednisolone. Although the inhibitory effects of naproxen on all these enzymes were quite evident, indomethacin failed to inhibit APase activity. Prednisolone did not significantly inhibit LZ and APase activities in granuloma. In the curative test, prednisolone caused a marked decrease in the weight of the granuloma already formed and in the volume of the exudate, but with naproxen and indomethacin there was only a slight decrease. Naproxen and indomethacin induced slight but significant inhibition of LZ and CL activities, while prednisolone showing a weak inhibition of CL activity only. From these results, it may be concluded that anti-inflammatory and anti-rheumatic effects of naproxen are partly attributable to its inhibitory actions on these lysosomal enzymes.

An immunological study was carried out of 51 patients with pulmonary sarcoidosis. Two groups of patients were singled out: receiving and not receiving glucocorticoid treatment (prednisolone: 0.3 mg/kg of body weight). It was found that patients with pulmonary sarcoidosis revealed changes of the functional state of neutrophils and monocytes of the peripheral blood manifested in a reduction of their absorptive capacity, number of rosette-forming cells, adhesiveness of neutrophils, increase of oxygen-dependent metabolism, production of lysozyme by neutrophils. Prednisolone treatment effected the state of neutrophils manifested in a reduced acid phosphatase activity; the production of lysozyme increased, the absorptive capacity normalized.

A 65-year-old man was diagnosed with systemic sclerosis on the basis of skin thickening and positivity of anti-Scl-70 antibodies. Because myogenic enzymes, such as creatinine phosphokinase and aldorase, were also elevated, myopathy or myositis associated with systemic sclerosis was considered. Muscle magnetic resonance imaging and gallium scintigraphy did not show abnormalities. Findings of muscle biopsy demonstrated presence of noncaseating granulomas with multinucleated giant cells. In addition, serum angiotensin-converting enzyme and lysozyme were elevated, and therefore a diagnosis of sarcoid myopathy was made. Further, renal sarcoidosis was revealed with renal biopsy. Prednisolone (40 mg/day) improved both the myopathy and nephritis. Sarcoid myopathy is a rare condition, but it should be considered when myogenic enzymes are elevated in the patient with systemic sclerosis. Further, muscle biopsy may be essential to make an accurate diagnosis in such condition.
