The immunosuppressive activity of leflunomide is expressed after conversion to its pharmacologically active metabolite A77 1726. Leflunomide is a potent immunosuppressant that inhibits both T-cell and B-cell activity. To date, no pharmacokinetic data have been reported on leflunomide or A77 1726, primarily because of lack of a suitable method for its analysis. We describe here the development and evaluation of a reverse-phase high-performance liquid chromatographic (HPLC) method for the analysis of A77 1726 in whole blood or plasma from humans or rabbits. In human blood, the method exhibited good analytic recoveries from 78 +/- 13.5% to 108 +/- 4.8% (mean +/- SD) for drug concentrations ranging from 400 to 100,000 micrograms/L. When using a sample volume of 0.25 ml the sensitivity of the method was found to be 400 micrograms/L, with a working standard range of up to 200,000 micrograms/L. The sensitivity of the method can be increased to 40 micrograms/L when 1.0 ml of sample is used. Between-run coefficients of variation of 12.2 and 14.7% at A77 1726 mean concentrations of 1,006 and 8,146 micrograms/L were found for this method. No significant differences in recovery of drug were noted when either human or rabbit plasma or whole blood was used as the medium of analysis. In whole-blood specimens, A77 1726 was found to be stable for up to 10 days at -20 or -70 degrees C.

Leflunomide is a new immunosuppressive medicine that has been effectively used in the therapy of rheumatoid arthritis and subsequently used with success in animal models and patients with systemic lupus erythematosus (SLE). However, its use has also been associated with significant and serious adverse reactions involving hematological, hepatic, immune, dermatological and respiratory systems. In the current review, we attempt to describe the two sides of this drug in the treatment of SLE.

Angiomyomatous hamartoma (AMH) is a rare disease with predisposition for inguinal and femoral lymph nodes. Histologically, it is characterized by replacement of lymph nodal parenchyma with irregularly distributed thick walled blood vessels, haphazardly arranged smooth muscle cells, variable amount of fat and fibrous tissue in a sclerotic lymphatic stroma. Few cases have also been reported in popliteal and sub - mandibular location. The exact pathogenesis is still not known. Although this entity is very rare, its recognition is important in discriminating it from other benign and malignant vascular lesions of lymph nodes.

62 patients with a mean age of 54 were included. 89% were female and had positive rheumatoid factor and 83% had radiological erosions. Eighty eight percent were in doses of 15 mg MTX, 4.9% with 10 mg and 25 mg at the beginning of LF treatment. Twenty four percent suffered from adverse events and 33% left the medication by 6 months. Among adverse events, 6 patients had diarrhea, 5 increased hepatic enzymes, 3 alopecia, 3 weight loss, and 2 had anemia and leucopenia. Eight patients stopped the medication in 6 months, but only 5 did because of adverse events. There was not significant statistical difference in adverse events between patients with different dose or routes of administration of MTX.

We selected from the ESPOIR cohort 370 patients receiving MTX or leflunomide (LEF) for ≥3 months within the first year of follow-up. Patients were assessed clinically every 6 months, and structural damage progression seen on radiography was measured by the van der Heijde-modified Sharp score (vSHS) at 1 year. RRP was defined as an increase in the vSHS≥5 points during the first year.

Treatment continuation after 12 months was similar for etanercept (68.6% (95% confidence interval, 62% to 75%)) and infliximab (65.4% (58% to 73%)) but lower for anakinra (59% (41% to 77%)). Treatment continuation was more likely for patients on combinations of biological agents and DMARDs than for those on infliximab or etanercept alone. Patients treated with biological agents were more severely ill than those in the control group and had more previous DMARD failures. After adjustment for baseline differences, the continuation rates were higher in patients treated with biological agents than in comparable control patients treated with leflunomide or leflunomide/methotrexate.

ABCG2 protein expression was stable for at least 4 weeks when CEM/SSZ cells were grown in the absence of SSZ, but gradually declined, along with SSZ resistance levels, to non-detectable levels after withdrawal of SSZ for 6 months. Rechallenging with SSZ led to a rapid (<2.5 weeks) resumption of SSZ resistance and ABCG2 expression as in the original CEM/SSZ cells. CEM/SSZ cells displayed diminished sensitivity to the DMARDs leflunomide (5.1-fold) and methotrexate (1.8-fold), were moderately more sensitive (1.6-2.0 fold) to cyclosporin A and chloroquine, and markedly more sensitive (13-fold) to the glucocorticoid dexamethasone as compared with parental CEM cells.

No single therapeutic agent has been found to be universally effective for rheumatoid arthritis, so regimens using combinations of drugs have become the rule. Recently, several new agents with unique mechanisms of action have been introduced and found to produce various degrees of clinical benefit. Among these agents are folate and purine antagonists, alkylating agents, and antipyrimidines. Chimeric (mouse/ human) monoclonal antibody to tumor necrosis factor-alpha and human recombinant interleukin-1 receptor antagonist await approval for general use but have undergone considerable study.

A multidisciplinary panel of experts in RA was convened. Important questions, pertinent to the use of leflunomide in the treatment of RA, were defined by consensus at an initial meeting. Each question was allocated to subgroups of two or three members, who worked separately to prepare a balanced opinion, based on published literature, data from individual patients taking part in phase II and phase III clinical trials provided by Aventis, and data from a USA-based medical claims database (AETNA). The full group then reconvened to agree on an overall consensus statement. Recommendations concerning efficacy and tolerability versus comparator drugs and placebo were derived from two new meta-analyses.

Twenty two studies (1674 patients) were included. Plasma exchange as adjunctive therapy significantly reduces the risk of end-stage kidney disease at 12 months (five studies: RR 0.47, CI 0.30 to 0.75). Four studies compared the use of pulse and continuous administration of cyclophosphamide. Remission rates were equivalent but pulse treatment causes an increased risk of relapse (4 studies: RR 1.79, CI 1.11 to 2.87) compared with continuous cyclophosphamide. Azathioprine has equivalent efficacy as a maintenance agent to cyclophosphamide with fewer episodes of leukopenia. Mycophenolate mofetil may be equivalent to cyclophosphamide as an induction agent but resulted in a higher relapse rate when tested against Azathioprine in remission maintenance. Rituximab is an effective remission induction agent. Methotrexate or Leflunomide are potential choices in remission maintenance therapy. Oral co-trimoxazole did not reduce relapses significantly in Wegener's granulomatosis.

OBJECTIVES: Drugs used for the treatment of rheumatoid arthritis (RA) have the potential to affect cardiovascular risk factors. There is concern that corticosteroids, non-steroidal anti-inflammatory drugs (NSAIDs) and COX-2 inhibitors could affect cardiovascular risk adversely, while drugs such as the antimalarial, hydroxychloroquine, may have beneficial effects. However, there is limited information about cardiovascular risk factors in patients with RA receiving different drugs. METHODS: We measured cardiovascular risk factors including systolic and diastolic blood pressure, serum HDL and LDL cholesterol, glucose and homocysteine concentrations and urinary F(2)-isoprostane excretion in 169 patients with RA. Risk factors were compared according to current use of corticosteroids, methotrexate, antimalarials, NSAIDs, COX-2 inhibitors, leflunomide and TNF-alpha blockers. Comparisons were adjusted for age, sex, race, disease activity (DAS28 score), current hypertension, diabetes, smoking status and statin use. RESULTS: No cardiovascular risk factor differed significantly among current users and non-users of NSAIDs, COX-2 inhibitors, methotrexate and TNF-alpha blockers. Serum HDL cholesterol concentrations were significantly higher in patients currently receiving corticosteroids (42.2 +/- 10.5 vs. 50.2 +/- 15.3 mg/dL, adjusted P < 0.001). Diastolic blood pressure (75.9 +/- 11.2 vs. 72.0 +/- 9.1 mm Hg, adjusted P = 0.02), serum LDL cholesterol (115.6 +/- 34.7 vs. 103.7 +/- 27.8 mg/dL, adjusted P = 0.03) and triglyceride concentrations (157.7 +/- 202.6 vs. 105.5 +/- 50.5 mg/dL, adjusted P = 0.03) were significantly lower in patients taking antimalarial drugs. Plasma glucose was significantly lower in current lefunomide users (93.0 +/- 19.2 vs. 83.6 +/- 13.4 mg/dL, adjusted P = 0.006). CONCLUSIONS: In a cross-sectional setting drugs used to treat RA did not have major adverse effects on cardiovascular risk factors and use of antimalarials was associated with beneficial lipid profiles.

In summary, 1.7 years after transplantation, bortezomib rescue has been durably effective in salvaging our patient with refractory antibody mediated rejection. The only price has been persistently high levels of BK viruria. The presence of ongoing and even recurrent donor specific antibody has made it difficult to reduce immunosuppression further, and the concern that the high levels of BK viruria will eventually progress to viremia and nephropathy necessitates continued therapy with very low dose cidofovir and leflunomide. The absence of C1q binding DSA with stable renal function may provide some reserved optimism that the DSA that is detectable by convention Luminex assay may have reduced pathological implications. However, more data and prolonged follow-up are needed to determine whether or not non-complement binding DSA has an adverse pathological role.

116 were included (mean age = 55 years, 70% women). Almost 21.7% stopped treatment for lack of efficacy (after a mean delay of 3.6 months), 16% for secondary loss of efficacy (median = 7 months), and 32% for the occurrence of an adverse event (half within 4 months). Over a similar time frame in clinical trials, in patients of about the same age and sex but with less severe disease, the corresponding figures were 7-17% for lack or loss of efficacy, and 14-22% for adverse effects. At one year of follow-up, the discontinuation rate was 70% in the cohort compared to 28-47% in clinical trials.

In vitro, all combinations with 1,25(OH)2D3 were synergistic. The strongest synergism was seen with the inhibitors of interleukin 2 secretion, cyclosporine and FK506 (indexes 0.16 and 0.27, respectively). The weakest synergism was observed in combinations using A802715, a second-signal inhibitor (index 0.52), or the nucleotide synthesis inhibitor mycophenolate mofetil (index 0.43). In vivo, analogs of 1,25(OH)2D3 share the in vitro-observed synergism with 1,25(OH)2D3. Moreover, the differences in synergism with different immunomodulators were also present in vivo, where the best synergism was again seen in combination with cyclosporine (up to 100% paralysis protection).

The main objectives of medical therapy in ankylosing spondylitis (AS) are to relieve pain, stiffness and fatigue and to prevent structural damage. The Assessment in Ankylosing Spondylitis Working Group has proposed different domains with specific instruments to assess the efficacy of therapeutic agents classified as symptom-modifying and disease-controlling antirheumatic drugs. Non-steroidal antiinflammatory drugs (NSAIDs) are still the first-line treatment in the management of AS, and they are effective in controlling buy arava symptoms such as pain and stiffness and maintaining mobility in many patients. A recent randomized trial suggested that the progression of radiological damage occurs less on continuous use of celecoxib compared with on-demand use. If such findings were confirmed by other studies, the therapeutic value of NSAIDs in AS may extend beyond symptom control. However, for each individual patient, the expected advantages of treatment with NSAIDs should be weighted against any possible gastrointestinal and cardiovascular disadvantages. Disease-modifying antirheumatic drugs (DMARDs) are widely used for second-line therapy in AS, but the evidence for their efficacy is poor. The term 'DMARD' has been borrowed from rheumatoid arthritis, and none of the DMARDs have been shown to prevent or significantly decrease the rate of progression of structural damage which is required to be qualified as a disease-controlling antirheumatic drug for AS. Sulphasalazine is the most extensively studied DMARD and studies suggest some degree of clinical benefit confined to peripheral joint involvement, but no evidence of benefit in axial disease. Methotrexate, which is the gold standard DMARD in rheumatoid arthritis, does not seem to have a substantial therapeutic effect in AS on axial or peripheral joint involvement. Leflunomide appears to exert little beneficial effect, if any, even on peripheral joint involvement. There is also good evidence that local therapy with corticosteroids is effective and may be used in selected patients. Oral corticosteroids may be somewhat effective in relieving the symptoms of AS, but this has not been formally studied. Small studies have reported favourable results with intravenous methylprednisolone pulse therapy, but the effect is temporary. Pamidronate and thalidomide have been used in some preliminary trials but need further studies to assess their potential role in treating AS patients resistant or intolerant to other forms of treatment. Treatment with tumour necrosis factor blockers is not discussed in this review.

The effect of leflunomide (Lef) donor pretreatment (DPT) on rat cardiac allograft survival was investigated. In untreated Lewis recipients of untreated DA hearts, median graft survival was 5 days. DPT (Lef 5 or 10 mg/kg per day for 30 days) reduced median graft survival to 4.0 buy arava and 4.5 days, respectively. In immunosuppressed (Lef 5 mg/kg for 10 or 30 days) Lewis recipients of untreated DA hearts, median graft survival was 21 and 33 days, respectively. DPT with Lef 5 mg/kg per day for 5 days or 30 days reduced median graft survival to 12 and 23.5 days, respectively (p < 0.05). DPT with Lef resulted in earlier graft rejection but the histological appearance at the time of rejection was the same as in untreated controls. DPT with Lef resulted in a 40% reduction in MHC class II-positive cells in the heart. Histological examination of rejecting hearts showed no obvious difference in the nature of the rejection process between DPT and untreated control hearts. The paradox between class II reduction but earlier rejection indicates that DPT is exerting a deleterious effect through some unrecognized property of the graft.

FK778 (Fujisawa Healthcare Inc.) is an immunosuppressant structurally similar to A771726, the active metabolite of leflunomide (Aventis Pharmaceuticals), but with a clinically relevant shorter serum half-life. Leflunomide, a tolerated and efficacious immunosuppressive agent in patients receiving allograft transplantations, was reported to be active against HCMV and HSV-1. Here we report that FK778 is a potent and effective inhibitor of HCMV, and that its mode of antiviral action appears to mirror the biochemical mechanisms elsewhere described to be responsible for its immunosuppressive properties: inhibition of protein tyrosine phosphorylation and inhibition of cellular de novo pyrimidine biosynthesis. Initial HCMV-mediated activation of the EGF receptor/phosphatidylinositol 3-kinase (PI3-K) pathways and Sp1 and NF-kappaB were partially inhibited by FK778. The second tier (phase) of PI3-K, Sp1, and NF-kappaB induction by HCMV was more sensitive to FK778. Treatment of HCMV-infected cells with FK778 prevented the appearance of HCMV proteins some 12-24h post infection, buy arava and inhibited viral DNA synthesis. In our assays, leflunomide also reduced HCMV DNA levels. The antiviral activity of FK778 was reversed in cell culture by treatment with uridine, consistent with specific inhibition of dihydroorotate dehydrogenase (DHODH), a required enzyme in the de novo biosynthesis of pyrimidines. This report substantiates the clinical possibility of a single drug treatment to achieve immunosuppression and inhibit opportunistic herpesvirus infections. Our results differ from descriptions of leflunomide acting as an inhibitor of HCMV cytoplasmic capsid formation. Additionally, this study indicates that DHODH may be an effective cellular antiviral target.

In contrast to rheumatoid arthritis, in psoriatic arthritis (PsA), the efficacy of disease-modifying antirheumatic drugs (DMARDs) combination has not been documented. We conducted a retrospective study to evaluate the effectiveness of leflunomide (LEF) addition in 11 PsA patients with articular manifestations that failed to respond to methotrexate (MTX) monotherapy [disease activity score in 28 joints (DAS28) > 3.2)]. Eight of them, all with moderate disease activity (DAS28 < 5.1) at baseline, tolerated the combination. A buy arava statistically significant improvement of the mean DAS28, based on erythrocyte sedimentation rate (ESR), and its variables, and C-reactive protein (CRP) at 12-16 weeks after LEF addition was observed. Mean change of DAS28 in patients with polyarticular disease did not differ compared with those with oligoarticular. Based on the European League Against Rheumatism (EULAR) response criteria, none of our patients achieved a good response, seven had a moderate response, and one was a non-responder. The two patients with the lower DAS28 at baseline attained low disease activity (LDA, DAS28 ≤ 3.2), while none reached remission (DAS28 ≤ 2.6). Achievement of clinical remission or at least LDA has been recently proposed as the goal of treatment in PsA. Our results imply that LEF addition may serve as an alternative therapeutic modality for patients with moderately active PsA and, as lower as possible, residual disease activity after the initial therapy with MTX alone.

Pulmonary alveolar proteinosis is an uncommon disorder marked by the abnormal accumulation of surfactant within the alveoli. Secondary pulmonary alveolar proteinosis develops in patients who are immunosuppressed, usually with corticosteroids. We present a case of biopsy-proven pulmonary alveolar proteinosis in a patient undergoing therapy with the disease-modifying antirheumatoid arthritis drug leflunomide (Arava; Aventis Pharmaceuticals, Bridgewater, NJ). He was treated with whole lung lavage and discontinuation of leflunomide with good results. This buy arava is the first reported association of secondary pulmonary alveolar proteinosis with leflunomide therapy. Pulmonary alveolar proteinosis should be considered in patients with diffuse lung disease that develops while on disease-modifying antirheumatoid arthritis drug therapy.

The isoxazole derivative Leflunomide (HWA 486) is a novel immunoregulatory and anti-inflammatory drug. Affinity chromatography was used to purify and identify Leflunomide binding proteins, which might play a role as potential cellular targets in the molecular mode of action. The Leflunomide derivative A 0273 was covalently coupled to a Fractogel(R) matrix. This column was used to separate a cytosolic protein extract of the macrophage cell line RAW 264.7 by several selected and specific gradient elution steps. Proteins that were specifically eluted through the active metabolite of Leflunomide, A 1726, were identified by subsequent protein sequence analysis. This allowed us to specify 10 cytosolic proteins, which bind with high affinity to this matrix. Three of them, glyceraldehyde 3-phosphate dehydrogenase, pyruvate kinase and phosphoglycerate mutase belong to the second part of the glycolytic pathway. The binding specificity of these protein/drug interactions was further evaluated using BIAcore(R) analysis. Kd values of glyceraldehyde 3-phosphate dehydrogenase, pyruvate kinase and lactic dehydrogenase were similar to the Kd value of a known Leflunomide target protein, dihydroorotate dehydrogenase. In order to elucidate the features as well as the overall relevance of these results, cytosolic fractions of three additional cell lines MOLT-4, A20.2J, HeLa were compared using the same chromatographic protocol. The elution profiles as buy arava well as subsequent Western blot analyses confirmed the data obtained previously for the macrophage cell line RAW 264.7.

Leflunomide and its active metabolite, A771726, are structurally unrelated to immunosuppressive agents currently under investigation. Previous in vitro studies have revealed that leflunomide primarily inhibits interleukin-2-stimulated T cell proliferation. In the current study, we have extended our previous work and demonstrate that leflunomide prevents T cell progression induced by phytohemagglutinin into the S phase of the cell cycle. To discriminate further the action on T cells of leflunomide from other immunosuppressive agents, we performed kinetic studies where leflunomide was added either after the initiation of mixed lymphocyte cultures (MLC) or after interleukin-2 stimulation of CTLL-4 cell proliferation. These studies revealed that leflunomide acted comparably to rapamycin, but was distinct from brequinar sodium in the MLC, and from cyclosporine and mycophenolic acid in both MLC and CTLL-4. Although previous Sinequan Generic Name biochemical studies indicated that leflunomide can inhibit src-family tyrosine kinase activity, more recent studies have suggested that leflunomide can also inhibit pyrimidine synthesis. Our data demonstrate that the ability of leflunomide (25-100 microM) to inhibit MLC and CTLL-4 cell proliferation is partially antagonized by uridine (25-100 microM), and support the hypothesis that leflunomide inhibits pyrimidine synthesis in T cells. Unique molecular mechanisms of immunosuppression suggest that drug combinations may result in synergistic immunosuppression. Our in vitro studies revealed synergistic inhibition of T cell proliferation with the combinations of leflunomide with cyclosporine or with rapamycin. We have extended those studies to quantitate inhibition of MLC by the combinations of leflunomide and brequinar sodium or mycophenolic acid.

The inability to provide an adequate supply of human organs for clinical transplantation has created a strong interest in the use of nonhuman, especially nonprimate, organs. The first biological obstacle confronting such discordant transplantations is a series of violent reactions that result in hyperacute rejection of the xenograft. Significant advances in controlling hyperacute rejection have been achieved recently through the generation of transgenic pig donors bearing human complement regulatory proteins. However, when hyperacute rejection is averted, the xenografts are rejected in 2-70 days in spite of high- Tofranil Pm Dosage dose immunosuppression, by a process collectively termed delayed xenograft rejection. Delayed xenograft rejection is characterized by a refractoriness to conventional immunosuppression, extensive xenoreactive antibody deposition, and cellular infiltration that is dominated by macrophages. We have examined the features of extended host and graft response in the concordant hamster-to-rat xenotransplant model, where such features have historically been obscured by early graft destruction. Hamster hearts transplanted into rats do not encounter hyperacute rejection but are rejected within 3-4 days when xenoreactive antibody titers rise exponentially to levels that elicit a classical antibody- and complement-mediated acute xenograft rejection. We have successfully blocked acute xenograft rejection by a combination of immunosuppressive agents, leflunomide, and cyclosporine. Stopping the immunosuppression resulted in graft rejection that is histologically characterized by extensive xenoreactive antibody deposition and cellular infiltration that is predominantly composed of macrophages. We have noted the similarities between the histopathology of rejection of long-surviving concordant xenografts and that described for discordant xenografts and refer to the process of rejection of concordant grafts that have escaped acute xenograft rejection, delayed xenograft rejection.
