Objective: To compare the incidence of gastroduodenal ulcers in patients with osteoarthritis (OA) treated with therapeutic doses of the novel COX-2 selective inhibitor, lumiracoxib (COX189, Prexige), and the standard nonsteroidal antiinflammatory drug (NSAID) ibuprofen. The COX-2 selective inhibitor celecoxib was included as an active control., Methods: In this randomized, multicenter, double-blind, parallel-group study, eligible patients were randomized to receive lumiracoxib 200 mg (n = 264) or 400 mg (n = 260) once daily (qd), ibuprofen 800 mg (n = 260) 3 times daily (tid), or celecoxib 200 mg qd (n = 258) for 13 weeks. The incidence of gastroduodenal ulcers and erosions was determined by endoscopy prior to randomization, and after 4 weeks and 13 weeks of treatment (end of study). Frequencies of adverse events were also recorded., Results: The cumulative incidence of gastroduodenal ulcers >/= 3 mm in diameter was significantly lower in the lumiracoxib groups (200 mg: 4.3%; 400 mg: 4.0%) than in the ibuprofen group (15.7%; p < 0.001) and similar to the celecoxib group (3.2%). In the ibuprofen group, a significantly greater number of patients (6.0%) had > 10 gastroduodenal erosions compared with lumiracoxib 200 mg (1.2%; p < 0.01), lumiracoxib 400 mg (1.6%; p < 0.05), and celecoxib (2.4%; p < 0.05). A greater number of patients in the ibuprofen group discontinued treatment due to an adverse event compared with both lumiracoxib groups and the celecoxib group., Conclusion: In patients with OA, lumiracoxib 200 mg or 400 mg qd was associated with a significantly lower risk of gastroduodenal ulceration than ibuprofen 800 mg tid, and was similar to celecoxib 200 mg qd.

An attempt was made to study the incidence of gout and hyperuricemia among the workers of the Moscow meat-packing plant exposed to high food purine loads. Using extensive clinical material (535 men and 1121 women) the authors established that gout was diagnosed 33 times more often in men of this plant than in the muscular population of other towns of the country. Moderate hyperuricemia was revealed in every second of the examinees. Marked hyperuricemia was noted 1.8 times more often, it being 3.4 times more often in men working at this plant as compared to the whole muscular population of the country. There was a direct dependence of the level of hyperuricemia in men working in this industry on their service record. The levels of moderate hyperuricemia in all groups of men and in some groups of women directly depended on the amount of daily purine loads. Marked hyperuricemia among the examined men is a factor of risk in the development of load and among the examined women an indicator of risk (i. e. warning) of possible metabolic changes which require an adequate dietetic and therapeutic correction.

The authors studied the arthroscopic picture of the knee joint in 50 male patients, 40 of whom had a genuine gout and 10 a doubtful one. A high diagnostic significance of arthroscopy was emphasized, it rose with the use of a morphological analysis of samples of synovial membrane and villi obtained by means of target biopsy, microscopy and chemical identification of urate.
