Celecoxib, a highly selective COX-2 inhibitor, is safe in aspirin-induced asthma patients.

BACKGROUND: In 5-10% of adult patients with asthma, aspirin and most other nonsteroidal anti-inflammatory drugs (NSAIDs) precipitate acute asthmatic attacks. Therefore, choosing an alternative anti-inflammatory agent for patients who have suffered adverse reactions to a nonsteroidal anti-inflammatory agent is a common problem in clinical practice. The discoveries that cyclooxygenase COX-2 is an inducible form of COX involved in inflammation and COX-1 is the major isoform responsible for the production of prostaglandins have provided a reasonable basis for the development of specific COX-2 inhibitors as a new class of anti-inflammatory agents. OBJECTIVE: The purpose of this study is to demonstrate that celecoxib, a specific inhibitor of COX-2, does not cause asthmatic attacks in patients with aspirin and/or other nonsteroidal anti-inflammatory drug-induced asthma. METHODS: We studied 33 patients, all of whom suffered from asthma induced by at least two different NSAID drugs. They were challenged in a single-blind manner with different doses of celecoxib on three different days, until either the therapeutic dose of 200 mg or intolerance was reached. Each patient was rechallenged with 200 mg celecoxib seven days later if no evidence of intolerance was previously observed. RESULTS: Celecoxib 200 mg was proven to be well tolerated in all 30 three aspirin- and NSAID-induced asthma patients. CONCLUSION: Our study appears to demonstrate that celecoxib is a suitable NSAID in aspirin-induced and/or nonsteroidal anti-inflammatory drug-induced asthma patients.

[Nitrates in canned spinach. Effects of technological treatments].

During the last twenty years, the nitrate content of spinach has regularly increased along with the use of nitragenous fertilizers. A study made in the center of Britain (France) shows that along with this growing nitrate content, the quantity of raw harvested spinach has practically doubled in twenty years. But for the same quantity of raw harvested spinach, the yield of canned spinach has noticeably lowered. In a cannery trials made to lower the nitrate levels (preheating, blanching, renewing water blanching) led to a loss of about 45% of nitrate (on a dry matter basis). However nitrate levels stay about the same in one kg of raw spinach and in one kg of processed spinach coming from the same batch. The only answer seems to be able and come from better agricultural practices.
