152 Lander et al., Lupus. 2002 Data from a retrospective, open-labeled, cohort study in 50 systemic lupus erythematosus patients seen by a community based rheumatologist and a MedLine search (using MeSH headings) of all articles pretaining to the use of NSAIDs in patients with systemic lupus erythematosus since 1996. To evaluate the safety and efficacy of Celecoxib in systemic lupus erythematosus patients both with and without a self-reported sulfa drug allergy and to review the literature on the use of NSAIDs in SLE patients. 154 Devillier P., Presse Med. 2001 Citing and reviewing results from published literature. To give an overview of the pharmacology of NSAIDs and ear nose and throat (ENT) pathology. 164 Deray G., Presse Med. 2001 Data from different studies. To review the renal effects of NSAIDs. • Treatment periods were 1 – 9 months. • In the cohort of Celecoxib-treated SLE patients the majority of patients demonstrated some improvement and little toxicity. • SLE patients with self-reported sulfa allergies were not more likely to have adverse reactions than non-sulfa allergic patients. • This literature review reveals that structural dissimilarities between Celecoxib and sulfonamide antimicrobials may make true cross-allergenicity less likely to be a clinical problem. → Results suggest that patients with SLE can be safely and effectively treated with Celecoxib. → Since several hundred thousand lupus patients take NSAIDs regularly, and since drug toxicity is a major concern in SLE patients, creation of evidence-based guidelines for the use of these agents, including COX-2 inhibitors, should be undertaken. • No indication for anti-inflammatory action in the ENT conditions, neither for NSAIDs nor COX-2 inhibitors. • Official indication guideline in France concerning ENT disease in children and adults without risk factor are that there is no need to institue NSAID treatment at an antiinflammatory dose in combination with general antibiotic therapy, except when there is an important inflammatory component. • NSAIDs are not indicated in nasal polyposis and contraindicated in case of intolerance to NSAID, observed in ≈ 15-20% of patients with nasal polyposis. • High doses, age over 60 years and history of severe GI complications are factors increasing the risk of severe GI AEs of NSAIDs. Minor AEs and severe AEs are significantly reduced with COX-2 inhibtors. • In patients with asthma triggered by classical NSAIDs, COX-2 inhibitor do not trigger acute asthma. • COX-2 inhibitors are currently not indicated for children and not for ENT. • Renal effects of NSAIDs in decreasing order: Electrolyte imbalance (hyperkaliemia, edema, hypertension), acute renal failure, nephrotic syndrome associated with interstitial nephropathy, papillary necrosis. • Electrolyte disorders and acute renal failure are observed more frequently in patients with risk factors. • Some studies examining the renal effects of COX-2 inhibitors (Rofecoxib and Celecoxib) precised the long-term effect on BP, edema, kaliemia and renal function. All these studies, except CLASS point to the strictly identical renal effects of COX-2 inhibitors and nonselective NSAIDs. → Detection and avoidance of the risk factors allow a well tolerated treatment with selective and non-selective NSAIDs. The use of COX-2 inhibitors does not optimize the order of these risk factors. 182
