Anti-Inflammatory Agents, Non-Steroidal
Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions.They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.

Manganese Poisoning
Manganese poisoning is associated with chronic inhalation of manganese particles by individuals who work with manganese ore. Clinical features include CONFUSION; HALLUCINATIONS; and an extrapyramidal syndrome (PARKINSON DISEASE, SECONDARY) that includes rigidity; DYSTONIA; retropulsion; and TREMOR. (Adams, Principles of Neurology, 6th ed, p1213)
Antitubercular Agents
Drugs used in the treatment of tuberculosis. They are divided into two main classes: "first-line" agents, those with the greatest efficacy and acceptable degrees of toxicity used successfully in the great majority of cases; and "second-line" drugs used in drug-resistant cases or those in which some other patient-related condition has compromised the effectiveness of primary therapy.

The systemic load and efficient delivery of active 5-aminosalicylic acid in patients with ulcerative colitis on treatment with olsalazine or mesalazine. (1/215)
BACKGROUND: There have been reports of nephrotoxic reactions in patients with ulcerative colitis treated with 5-aminosalicylic acid (5-ASA) preparations. AIM: To compare the efficacy in delivery of active 5-ASA to the colon and the systemic load as the basis for potential long-term toxicity during treatment with olsalazine or mesalazine in patients with ulcerative colitis in remission. PATIENTS AND METHODS: Fifteen patients with ulcerative colitis were treated with olsalazine or mesalazine, each for 7 days in an open, randomized, crossover design study. 5-ASA and acetyl-5-ASA (Ac-5-ASA) in plasma and urine were measured by high performance liquid chromatography. RESULTS: The plasma concentration of 5-ASA was 1.2 +/- 0.1 micromol/L (mean +/- S.E.M.) for olsalazine and 8.0 +/- 1.9 micromol/L for mesalazine, while the plasma concentration of Ac-5-ASA was 2.8 +/- 0.2 micromol/L for olsalazine and 10.8 +/- 1.6 micromol/L for mesalazine. The amount of 5-ASA excreted in the urine was 68 +/- 30 micromol/24 h for olsalazine and 593 +/- 164 micromol/24 h for mesalazine. The amount of Ac-5-ASA in the urine was 1260 +/- 102 micromol/24 h for olsalazine and 3223 +/- 229 micromol/24 h for mesalazine. The urinary recovery of total 5-ASA plus Ac-5-ASA (as a percentage of the given dose) was 23 +/- 2.1% for olsalazine and 39 +/- 3.6% for mesalazine. The ratio between the plasma concentrations of mesalazine and olsalazine differed significantly both for 5-ASA (5.1) and Ac-5-ASA (3.6); for 5-ASA (9. 9) and Ac-5-ASA (2.6) in urine, and for the urinary recovery of total 5-ASA plus Ac-5-ASA (1.7). Moreover, in the mesalazine group there was a large variation in the individual plasma concentrations of 5-ASA and Ac-5-ASA, with maximal values 5-6-fold higher than that in the olsalazine group. CONCLUSION: The systemic load of active 5-ASA is significantly higher for mesalazine than for olsalazine, when based on the dosages given and when calculated on an equimolar basis. Some of the patients in the mesalazine group showed unexpected high levels of plasma and urinary 5-ASA concentrations, a finding which may have long-term safety implications. (+info)Antioxidant effects of aminosalicylates and potential new drugs for inflammatory bowel disease: assessment in cell-free systems and inflamed human colorectal biopsies. (2/215)
BACKGROUND: The therapeutic efficacy of 5-aminosalicylic acid in inflammatory bowel disease may be related to its antioxidant properties. AIM: To compare in vitro the antioxidant effects of conventional drugs (5-aminosalicylic acid, corticosteroids, metronidazole), with new aminosalicylates (4-aminosalicylic acid, balsalazide) and other potential therapies (ascorbate, N-acetylcysteine, glutathione, verapamil). METHODS: Compounds were assessed for efficacy in reducing the in vitro production of reactive oxygen species by cell-free systems (using xanthine/xanthine oxidase, with or without myeloperoxidase) and by colorectal biopsies from patients with ulcerative colitis using luminol-amplified chemiluminescence. RESULTS: 5-aminosalicylic acid and balsalazide were more potent antioxidants than 4-aminosalicylic acid or N-acetyl-5-aminosalicylic acid in cell-free systems. 5-aminosalicylic acid (20 mM) and balsalazide (20 mM) inhibited rectal biopsy chemiluminescence by 93% and 100%, respectively, compared with only 59% inhibition by 4-aminosalicylic acid (20 mM). Hydrocortisone, metronidazole and verapamil had no significant effect on chemiluminescence in any system. Ascorbate (20 mM) inhibited chemiluminescence by 100% in cell-free systems and by 60% in rectal biopsies. N-acetyl cysteine (10 mM), and both oxidized and reduced glutathione (10 mM), completely inhibited chemiluminescence in cell-free systems, but not with rectal biopsies. CONCLUSIONS: The antioxidant effects of compounds varies between cell-free systems and inflamed colorectal biopsies. The effect of drugs on the chemiluminescence produced by these two assay systems is useful for screening potentially new antioxidant treatments for inflammatory bowel disease. Ascorbate seems worth further study as a novel therapy. (+info)Review article: the efficacy of infliximab in Crohn's disease--healing of fistulae. (3/215)
In the management of fistulae, the current therapeutic approach is the use of a combination of antibiotics and/or a combination of immunomodulatory agents. However, clinicians treating patients with fistulae, particularly those with fistulizing Crohn's disease, have little data from controlled clinical trials of these pharmacologic agents or regimens to substantiate their use in treating this complication. Therapy with the anti-tumour necrosis factor-alpha antibody, infliximab, has shown promise in treating patients with Crohn's disease and those with the disease complicated by fistulae. A recent clinical trial was designed specifically to evaluate infliximab in the treatment of fistulizing Crohn's disease. Study results demonstrated infliximab to be the first therapeutic agent to show statistical efficacy in fistulae closure in a placebo-controlled trial. Therapy with the chimeric monoclonal antibody was characterized by a rapid onset of closure and a lasting benefit of action. Two patient cases from the clinical trial are presented to exemplify the dramatic effectiveness of this novel therapeutic approach in modulating the immune response of patients with this debilitating complication of Crohn's disease. (+info)Intestinal anti-inflammatory activity of UR-12746, a novel 5-ASA conjugate, on acute and chronic experimental colitis in the rat. (4/215)
The present study was undertaken to investigate the intestinal anti-inflammatory effects of UR-12746 on the acute and chronic stages of a trinitrobenzene sulphonic acid (TNBS) experimental model of inflammatory bowel disease (IBD) in the rat. UR-12746 is a novel, locally-acting compound which combines, through an azo bond, 5-aminosalicylic (5-ASA) and UR-12715, a potent platelet activating factor (PAF)-antagonist. UR-12746 oral pretreatment of colitic rats (50 and 100 mg kg(-1)) reduced acute colonic damage when evaluated 2 days after colonic insult. Postreatment for 4 weeks with UR-12746 (50 and 100 mg kg(-1)) resulted in a faster recovery of the damaged colonic mucosa, which was macroscopically significant from the third week. The intestinal anti-inflammatory effect of UR-12746 was associated with a decrease in leukocyte infiltration in the colonic mucosa, which was evidenced both biochemically, by a reduction in myeloperoxidase activity, and histologically, by a lower leukocyte count after morphometric analysis. This effect was higher than that seen with sulphasalazine, when assayed at the same doses and in the same experimental conditions. Several mechanisms can be involved in the beneficial effects showed by UR-12746: inhibition of leukotriene B(4) synthesis in the inflamed colon, improvement of the altered colonic oxidative status, and reduction of colonic interleukin-1beta production. The results suggest that the intestinal anti-inflammatory activity of UR-12746 can be attributed to the additive effects exerted by 5-ASA and UR-12715, the PAF antagonist compound, that are released in the colonic lumen after reduction of the azo bond by the intestinal bacteria. (+info)Minimal renal dysfunction in inflammatory bowel disease is related to disease activity but not to 5-ASA use. (5/215)
BACKGROUND: Conflicting data exist about proteinuria in inflammatory bowel diseases. It is still unclear whether the occurrence of proteinuria in inflammatory bowel disease patients is an extra-intestinal manifestation of disease or the result of adverse effects to medication, especially to aminosalicylates (ASA). METHODS: A total of 95 patients (51 with Crohn's disease and 44 with ulcerative colitis) were enrolled in the study. Disease activity was assessed by Crohn's Disease Activity Index (CDAI) or the Truelove index, respectively. Urine was collected over 24 h and protein excretion of specific marker proteins for tubular (alpha 1-microglobulin-alpha 1-MG) and glomerular (albumin-Alb, Immunoglobulin G-IgG) dysfunction was measured using a highly sensitive immunoluminometric assay. RESULTS: Out of 51 Crohn's disease patients, 20 showed elevated urinary alpha 1-MG. The amount of alpha 1-MGuria was strongly correlated to the CDAI (r=0.6, P < 0.001). Only four Crohn's disease patients showed slightly elevated values for glomerular proteins in urine. Similar results were obtained for ulcerative colitis: whereas only two ulcerative colitis patients showed albuminuria, tubular proteinuria was detected in 28 out of 44 ulcerative colitis patients. Proteinuria was strongly dependent on disease activity (P < 0.01) but was not related to ASA treatment. CONCLUSIONS: Proteinuria of tubular marker proteins occurs in the majority of inflammatory bowel disease patients and is related to disease activity rather than to ASA treatment. Tubular proteinuria seems to reflect a renal extra-intestinal manifestation of inflammatory bowel disease and may serve as a new relevant marker of disease activity. (+info)NO-mesalamine protects colonic epithelial cells against apoptotic damage induced by proinflammatory cytokines. (6/215)
The activation of a self-amplifying cascade of caspases, of which caspase-8 is the apical protease, mediates Fas-, tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL)-, and TNF-alpha-induced apoptosis in colon cell lines. Nitric oxide (NO) protects from apoptosis induced by Fas and TNF-alpha. We examined whether NCX-456, an NO-releasing derivative of mesalamine, protects colon epithelial cells from cytokine-induced apoptosis. Caco-2 and HT-29 cell lines express death factor receptors and are driven to apoptosis in response to incubation with Fas-agonistic antibody, TNF-alpha/interferon-gamma, and TRAIL. The two novel observations reported here are that 1) cotreatment of cells with NCX-456, but not mesalamine, resulted in concentration-dependent protection against death factor-induced apoptosis and inhibition of caspase activity, and 2) exposure to dithiothreitol, an agent that effectively removes NO from thiol groups, resulted in a 70% recovery of caspase activity, which is consistent with S-nitrosation as a major mechanism for caspase inactivation. These data suggest that caspase S-nitrosation represents a mechanism for protection of colonic mucosal epithelial cells from death factor-induced death. (+info)Olsalazine is not superior to placebo in maintaining remission of inactive Crohn's colitis and ileocolitis: a double blind, parallel, randomised, multicentre study. (7/215)
BACKGROUND AND AIMS: The benefit of 5-aminosalicylic acid therapy for maintenance of remission in Crohn's disease is controversial. The primary aim of this study was to evaluate the prophylactic properties of olsalazine in comparison with placebo for maintenance of remission in quiescent Crohn's colitis and/or ileocolitis. METHODS: In this randomised, double blind, parallel group study of olsalazine versus placebo, 328 patients with quiescent Crohn's colitis and/or ileocolitis were recruited. Treatment consisted of olsalazine 2.0 g daily or placebo for 52 weeks. The primary end point of efficacy was relapse, as defined by the Crohn's disease activity index (CDAI) and by clinical relapse. Laboratory and clinical disease activity indicators were also measured. Safety analysis consisted of documentation of adverse events and laboratory values. RESULTS: No differences in the frequency of termination due to relapse or time to termination due to relapse were noted between the two treatment groups (olsalazine 48.5% v placebo 45%) for either colitis or ileocolitis. The failure rate, defined as not completing the study, was significantly higher in olsalazine treated patients compared with placebo treated patients for the overall population (colitis and/or ileocolitis: olsalazine 65.4% v 53.9%; p=0.038). Similar failure rates were seen for patients with colitis. A significantly higher percentage of olsalazine treated patients experienced adverse gastrointestinal events. Drug attributed adverse events were reported more frequently in the olsalazine treated group with gastrointestinal symptoms being causally related to olsalazine treatment (olsalazine 40.7% v placebo 26.9%; p=0.010). Back pain was reported significantly more often by the placebo treated group. However, serious medical events did not differ between the two groups. Adverse events led to more early withdrawals in the olsalazine treated group than in the placebo treated group; thus average time in the study for patients in the olsalazine treatment group was significantly shorter than that of patients in the placebo group. CONCLUSIONS: Patients treated with olsalazine were more likely to terminate their participation in the trial than those taking placebo. This difference was not related to relapse of disease, as measured by CDAI and clinical measures, but rather was due to the development of intolerable adverse medical events of a non-serious nature related to the gastrointestinal tract. The gastrointestinal related events in the olsalazine treated group may be due to the difference in gastrointestinal status at baseline which favoured the placebo treatment group.

Balsalazide is a 5-aminosalicylic acid (mesalazine) pro-drug which has an inert carrier molecule instead of the sulfapyridine moiety of sulfasalazine. It is designed to deliver 5-aminosalicylic acid to the colonic mucosa without the sulfapyridine-associated side-effects encountered with sulfasalazine. Several studies have confirmed the efficacy and patient tolerance of balsalazide. When compared to mesalazine at equivalent doses, it induced symptomatic and complete remission of acute ulcerative colitis in a greater proportion of patients. In particular, patients with resistant left-sided disease were shown to have a higher probability of achieving remission. Balsalazide was beneficial in patients with troublesome nocturnal symptoms. It has a similar efficacy in maintaining remission when compared to sulfasalazine and mesalazine. The advantage of balsalazide over other 5-aminosalicylic acid compounds is its superior patient tolerability with minimal side-effects. (+info)
