Methods: The present study was performed on 11 patients with stable proteinuria who were diagnosed as AA amyloidosis secondary to rheumatological diseases confirmed by renal biopsies. The study had three consecutive stages (celecoxib 200 mg/day; indomethacin 100 mg/day; rofecoxib 25 mg/day.) Each was given for 4 weeks and a wash-out phase of 3 weeks was allowed between consecutive stages. Results: Although the decrease of proteinuria in the celecoxib period was higher than in the rofecoxib and indomethacin periods, the difference was not statistically significant. No statistically significant differences were found between serum urea, creatinine, creatinine clearance and urinary sodium excretion. Conclusion: In this study, no differences were found between indomethacin and the two selective COX-2 inhibitors in respect to proteinuria and renal functions in 11 patients with renal amyloidosis secondary to rheumatological diseases with varying degrees of proteinuria. Routine doses of NSAIDs brought no additional benefit to the ACE inhibitor use in terms of proteinuria and renal functions. The use of selective COX-2 inhibitors should be limited to their anti-inflammatory and analgesic effects in this population.eninfo:eu-repo/semantics/closedAccessUrology & nephrologyRofecoxibProteinuriaNon-steroidal anti-inflammatory drugsCyclooxygenase-2CelecoxibAmyloidosisRiskNaproxenCelecoxibResolutionRofecoxibCox-2 inhibitorsNephrotic syndromeRheumatoid-arthritisCardiovascular eventsGastrointestinal toxicityProteinuriaMaleKidney diseasesKidneyIndomethacinHumansFemaleDrug therapy, combinationCyclooxygenase 2 InhibitorsAmyloidosisAdultArticle0002378129000122-s2.0-3374483004523223711316756637Urology & nephrologyRofecoxib; Nonsteroid Antiinflammatory Agent; Cyclooxygenase 2 InhibitorsUreaSodiumRofecoxibNonsteroid antiinflammatory agentIndometacinCyclooxygenase 2 inhibitorCreatinineCelecoxibWeight gainUrea blood levelStatistical significanceSodium urine levelSide effectRheumatic diseaseProteinuriaPriority journalMaleKidney functionKidney biopsyKidney amyloidosisHuman tissueHumanFemaleEdemaCyspneaCrug tolerabilityCrug effectCreatinine blood levelClinical articleArticleAdult
