Arava users was lower than the comparison groups there was one death in the Arvaa group, 9 in the methotrexate group, and 82 in the DMARD group these rates, however, were not statistically different. These results are shown in the following table, and the rates shown are reported per 100 patient years except for mortality, where the rates are per 100, 000 persons ; . This table also captures the total patient years for each DMARD or DMARD combination.
In controlled studies, the following adverse events were reported, regardless of causality. Differences between ARAVA and placebo were observed for diarrhoea, elevated liver enzymes ALT and AST ; , hair loss and rash and evista.
Response, known as an ACR 20 Responder.66 An ACR 20 Responder must have at least 20 percent improvement demonstrated in 5 of core set measures of disease activity, including both tender and swollen joint counts.67 Using these criteria, Aventis applied a stringent primary analysis -- the ACR 20 Responder-at-Endpoint rate - to the phase IIl clinical trial data.68In both placebo-controlled trials, AravaB monotherapy was statistically significantly superior to placebo in reducing the signs and symptoms of RA after 6 months in MN301 ACR Responder-atEndpoint: Afava -49% vs. placebo-29% ; , G" and after 12 months in US301 41% vs. 19% ; , and statistically equivalent to the active comparator agents methotrexate and sulfasalazine ; .70 HRG cites only the 12-month efficacy data from the MN302 study, where a difference in ACR 20 Responder-at-Endpoint rate was observed in favor of methotrexate 57% ; over leflunomide 43% ; , although, as previously noted, the differences in the components were small and not meaningfully different from a clinical standpoint. However, HRG fails to reference the 12-month results of US301, in which there was no statistically significant difference in the ACR 20 Responder-at-Endpoint rate between AravaB 41% ; and methotrexate 35% ; .71 Indeed, the efficacy of Arava was consistent across all trials, whereas the efficacy of methotrexate varied substantially between trials.72 In addition to the efficacy demonstrated by ACR Response rates.

SHARED-CARE ; DMARD PRESCRIBING AND MONITORING INFORMATION Based on BSR's 2000 "Guidelines for Second Line Drug Monitoring", and on "Prescribing and Monitoring of DMARDs for Inflammatory Arthritis", in ARCs publication, Rheumatic Disease: In Practice, 2002, Number 8. LEFLUNOMIDE Arava ; Leflunomide: Suppresses the activated lymphocytes involved in inflammatory arthritis. Active metabolites have half-lives of up to 4 weeks, thus an initial loading dose may be given to rapidly reach therapeutic levels. Pre-treatment assessment: FBC, LFTs, U&Es and blood pressure. Administration: Oral, the tablets being swallowed whole with plenty of water. Absorption not affected by food. Typical dose regimen: 10-20 mg daily. A loading dose of 100 mg day for 3 days is recommended by some, but not all, rheumatologists, so be guided on loading by local consultant rheumatologists' instructions, then 10-20 mg daily. Precautions: Leflunomide may inhibit the metabolism of warfarin, phenytoin and tolbutamide. It has an extremely long halflife, so interactions with these and other drugs may occur long after leflunomide discontinued. Male female patients should not procreate within two years of discontinuing leflunomide. If procreation is being considered within 2 years of drug discontinuation, blood levels should be measured. If a severe side-effect occurs, or for any other reason rapid removal of its active metabolites is required, a washout procedure with cholestyramine 8gm three times a day or activated charcoal 50gm five times a day, each for 11 days, is available. Leflunomide increases susceptibility to infections, which should thus be treated promptly. Live vaccines are contraindicated. Leflunomide is contraindicated in patients with liver impairment or moderate to severe renal failure, serious infections, severe immunodeficiency states including AIDS, and severe hypoproteinaemia, including that due to nephrotic syndrome. Time to response: Begins after 4-6 weeks, but improvements may continue for 4-6 months. Monitoring requirements: FBC two-weekly for the first 6 months, then two-monthly. LFTs and blood pressure monthly for the first 6 months, then two-monthly. Action to be taken if monitoring shows abnormalities: WBC 4.0x109 l Withhold until discussed with hospital rheumatology service Neutrophilis 2x109 l Platelets 150x109 l 2-fold rise in ALT or AST from upper limit of reference range ; Rash, itch or mouth ulcers Withhold until discussed with hospital rheumatology service Withhold until discussed with hospital rheumatology service Withhold until discussed with hospital rheumatology service Withhold until discussed with hospital rheumatology service.
A S S Rheumatoid arthritis RA ; remains one of the most challenging diseases treated by physicians in the Rheumatology Division. RA is a chronic multisystemic inflammatory disease with autoimmine features associated with characteristic joint deformities and increased mortality rate. This disease affects about one percent of the population worldwide, most commonly middle-aged women. John A. Hurley, M.D. Current treatments with first and second line drugs are inadequate in that they only partially control established disease. They also have side effects that limit their use early in the disease process and interfere with prolonged administration. Thus, despite optimal use of current antirheumatic therapy, the outcome for many patients with RA consists of pain, severe functional decline and work disability. The gloomy recent data regarding the prognosis of RA with the use of therapeutic regimens suggests a need for new approaches to the treatment of this disease and better understanding of its pathogenesis. Fortunately our understanding of the mechanisms involved has recently increased dramatically. This has opened up the opportunity for new therapies directed toward specific cell interactions and toward the mediators that they produce. Over the last several years, two new nonsteroidal anti-inflammatory drugs and three new disease-modifying drugs have been introduced. Celecoxib Celebrex ; and Refecoxib Vioxx ; are the first anti-inflammatory drugs available in the United States that selectively block COX-2. Of importance, the efficacy of these COX-2 inhibitors does not differ substantially from that of conventional anti-inflammatory drugs. Their advantage is principally because of a reduced rate of adverse events, especially upper GI bleeding. The three new disease-modifying drugs are Exanercept Enbrel ; , Infliximab Remicade ; and Leflunomide Arava ; . Etanercept and Infliximab are tumor necrosis factor TNF ; antagonists that have powerful anti-inflammatory effects in patients with RA. TNF is a potent inflammatory cytokine expressed in increased amounts in the serum and synovial fluid of patients with RA. It promotes the release of other inflammatory cytokines and is crucial in recruitment of inflammatory cells into synovial tissues. As a result, TNF is a prime therapeutic target in patients with RA. Etanercept is a TNF receptor fused with human immunoglobin. Its purpose is to bind to soluble TNF thereby rendering it biologically , inactive. About 70 percent of patients receiving subcutaneous Etanercept at dosages of 25 mg twice a week have substantial improvement in the extent of joint inflammation, often within one to two weeks after initiation of therapy. This improvement can be enhanced by combination with methotrexate.weeks after initiation of therapy. This improvement can be enhanced by combination with methotrexate. Infliximab is a monoclonal antibody directed against TNF. It is given intravenously once every eight weeks after an initial "loading" dose. Potential long-term risks of these TNF antagonists have not been established. However, physicians have to be vigilant in assessing patients for increased risk of infection, malignancy or autoimmune disease. The cost of these drugs is considerable and in general they should be considered in patients with recalcitrant disease not well-controlled by methotrexate. Leflunomide Arava ; is a pyrimidine synthesis inhibitor, which is taken orally in a dose of 10 or mg per day. This follows an initial loading dose of 100 mg a day for the first three days. Its efficacy is generally equivalent to that seen with methotrexate. The Rheumatology Division is under the direction of John Hurley, M.D. and Jay Kenik, M.D., Associate Professor of Medicine. Both Dr. Hurley and Dr. Kenik received their medical degrees and completed their Internal Medicine residency training at Creighton University. Dr. Kenik completed a rheumatology fellowship at the University of Michigan in Ann Arbor. Dr. Hurley completed his rheumatology fellowship at the University of Toronto in Canada. Both doctors returned to Creighton in 1980 and have been on the faculty since that time. The Rheumatology Division has been quite active. In addition to seeing patients at Saint Joseph Hospital, Alegent Health Bergan Mercy Medical Center, and the Omaha VA Hospital, Creighton Rheumatology has expanded to multiple outreach areas. Patients are seen in Albion, Bellevue, Columbus, and Norfolk in Nebraska, as well as Denison, Harlan, Missouri Valley, Onawa, and Red Oak in Iowa and rocaltrol. Ments table 1 ; .

Affinity for ER protein Table 1 ; , which is interesting in the light of the high expression of ER mRNA in the secretory epithelial cells of the prostate, and the prostate cancer protective properties that have been associated with these compounds 30 ; . Zearalanols are fungal metabolites or derivatives thereof that have been associated with estrogenizing syndromes in cattle fed with mold-infected grain 8 ; . Despite the fact that zearalanols are structurally very different to known steroidal and nonsteroidal estrogens, they interact with the rat uterus cytosolic ER 31 ; . Also, in our competition assays -zearalanol interacted with both ER subtypes with a similar affinity Table 1 ; , as was reported previously for the rat uterus ER protein 31 ; . Abnormal sexual development in reptiles as well as the increasing incidence of certain human reproductive tract abnormalities such as hypospadias ; has been associated with increased exposure to and body burdens of so-called estrogenic environmental chemicals 32, 33 ; . These effects from estrogenic chemicals as, for instance, the pesticide methoxychlor and the plastics ingredient bisphenol A, are postulated to be mediated via the ER because these compounds have estrogenic effects increase of uterine weight ; in female rats 8, 32, 33 ; . Bisphenol A and methoxychlor both inhibited the binding of [125I]-E2 by the ER and ER protein, and the inhibition seemed to be stronger for the ER protein Table 1 ; . However, it was clearly a very low affinity interaction, and the fact cannot be excluded that it involved different sites on the ER than those involved in the binding of E2.
