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.

In this open study of patients with active AS only those with peripheral arthritis improved significantly with leflunomide treatment. Axial symptoms did not improve.
The year-2 cohort, comprising patients continuing into the second year of treatment with > or = 1 dose of study medication and > or = 1 followup visit after week 52, consisted of 235 patients (LEF n = 98; placebo n = 36; MTX n = 101). The mean (+/- SD) maintenance dose of LEF was 19.6 +/- 1.99 mg/day in year 2 and that of MTX was 12.6 +/- 4.69 mg/week. Statistical analyses used an intent-to-treat (ITT) approach. Statistical comparisons of the active treatments only were prospectively defined in the protocol.

Leflunomide (Arava) was approved for the treatment of rheumatoid arthritis by the regulatory authorities in the US and Europe in 1998. This approval was based on three pivotal randomised clinical trials conducted in the US and Europe. This report will focus on the use of leflunomide in rheumatoid arthritis based on the data from these trials as well information on the efficacy and safety learned from post release clinical experience.
For patients with moderate to severe psoriasis, there is a large range of variably effective and safe oral, systemic medications. With appropriate monitoring, these therapies may be used as either monotherapy or in combination with other therapies. Newer drugs in the research pipeline hold significant promise.

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).
