Renal toxicity was defined as toxicity directly associated with the intake of Celecoxib or non-selective NSAIDs, including acute tubular necrosis, acute tubulointerstitial nephritis, glomerulonephritis, renal papillary necrosis, chronic renal failure or salt and water retention. Comparisons were done between the Celecoxib users and non-selective NSAID users within

the main groups, as well as within the sub-groups as mentioned above, in relation to the demographic parameters and toxicities. Chi-square test was used to locate any significant differences between the groups. A total of 5850 patients’ charts were reviewed, of which 3121 patients had taken non-selective NSAIDs or Celecoxib continuously, at least for 3 months. From this group, 1881 patients were this website being followed up in the Department of Clinical Immunology and Rheumatology. Based on the exclusion criteria, 494 patients

were excluded and finally 1387 patients’ charts were included in the study. The number of patients within each sub-group, with their demographic data and diagnostic categories, are given in Table 1. There was a female preponderance in all the groups, as expected in systemic autoimmune connective tissue diseases. Age group and duration of disease were comparable in all the groups. Rheumatoid arthritis (RA) patients constituted more than half the number in all groups. This was followed by spondyloarthritis, psoriatic arthritis, other connective tissue disorders, osteoarthritis and crystal arthritis. No thrombo-embolic event was recorded www.selleckchem.com/products/Lapatinib-Ditosylate.html in any of the included patients in the adverse effect profile (Table 2). Major side effects documented were new onset hypertension, GI toxicities leading to discontinuation of the medication and renal failure. Minor side effects included edema and headache. The Celecoxib group (Group I) had significantly higher incidence of new onset hypertension (Table 3) as compared to the non-selective NSAID group (Group II) (P = 0.04).

This difference was not seen when continuous Celecoxib users were compared with those Celecoxib users who switched over to non-selective NSAIDs (Groups Ia and Ib) (P = 0.993). There was no difference between those who used Celecoxib continuously (Group Ia) and those patients who switched over to non-selective NSAIDs after a minimum PLEK2 of 3 months use of Celecoxib (Group Ib) in terms of any side effects (P = 0.553). Non-selective NSAID users (Group II), on the other hand, had significantly higher GI toxicity when compared to all Celecoxib users (Group I) (P = 0.001) and those who continued only on Celecoxib throughout the study period (Group Ia) (P < 0.001). 32/915 (3.49%) vs. 19/472 (4.02%) P = 0.6 28/915 (3.06%) vs. 6/472 (1.27%) P = 0.04 3/915 (0.327%) vs. 12/472 (2.54%) P = 0.001 1/915 (0.109%) vs. 1/472 (0.21%) P = 1.00 25/751 (3.32%) vs. 19/472 (4/02%) P = 0.03 23/751 (3.
