Small molecule tyrosine kinase inhibitors (TKIs) are developed to block intracellular signaling pathways in tumor cells, leading to deregulation of key cell functions such as proliferation and differentiation. Over 25 years ago, tyrosine kinases were found to function as oncogenes in animal carcinogenesis; however, only recently TKIs were introduced as anti cancer drugs in human cancer treatment. Tyrosine kinase inhibitors have numerous good qualities. First, in many tumor types they tend to stabilize tumor progression and may create a chronic disease state which is no longer immediately life threatening. Second, side effects are minimal when compared to conventional chemotherapeutic agents. Third, synergistic effects are seen in vitro when TKIs are combined with radiotherapy and/or conventional chemotherapeutic agents. In this article, we will give an update of the tyrosine kinase inhibitors that are currently registered for use or in an advanced stage of development, and we will discuss the future role of TKIs in the treatment of solid tumors. The following TKIs are reviewed: Imatinib (Gleevec/Glivec), Gefitinib (Iressa), Erlotinib (OSI-774, Tarceva), Lapatinib (GW-572016, Tykerb), Canertinib (CI-1033), Sunitinib (SU 11248, Sutent), Zactima (ZD6474), Vatalanib (PTK787/ZK 222584), Sorafenib (Bay 43-9006, Nexavar), and Leflunomide (SU101, Arava).

A total of 214 patients (mean age 57 years) were treated with leflunomide for >2 years; 74.8% of the patients were female. The mean disease duration was 4.1 years (range 0.1-26.6 years), and in 44% of patients, RA was first diagnosed within 2 years of entry into the phase III studies. The mean duration of leflunomide treatment was 4.6 years (range 2.8-5.8 years), and 32% of patients had received no previous treatment with disease-modifying antirheumatic drugs. ACR20, ACR50, and ACR70 response rates and HAQ scores at 1 year were maintained through year 4 or until the end point. No new types of adverse events were observed, and liver function was normal at baseline and at the end point in the majority of patients.

Between February and September 2009, 97 consecutive patients followed up at the University Hospital of the Universidade Federal de Santa Catarina, Brazil, were enrolled. RA patients on MTX alone or using the LEF and MTX combination had their medical records systematically reviewed. The alanine/aspartate aminotransferase enzymes were retrospectively analyzed since the beginning of treatment with MTX or MTX plus LEF. Hepatotoxicity was defined as an increase of at least two-fold the upper limits of normal of the liver enzymes.

Long-term allograft survival poses a major problem in pediatric renal transplantation, with allograft nephropathy being the principal cause of graft failure after the first post-transplant year. The mechanisms of nephron loss resulting in graft dysfunction are multiple, comprising both immunologic factors such as acute and chronic antibody- or T-cell-mediated rejection and non-immunologic components. The latter include peri-transplant injuries and renovascular lesions (renal artery stenosis, thrombosis) as well as cardiovascular risk factors such as arterial hypertension and hyperlipidemia. Another relevant issue leading to progressive nephron loss and declining kidney transplant function is acute and chronic nephrotoxicity induced by the calcineurin inhibitors (CNIs) ciclosporin (cyclosporine microemulsion) and tacrolimus. Furthermore, the presence of an abnormal lower urinary tract as well as bacterial (recurrent pyelonephritis) and viral (cytomegalovirus [CMV], polyomavirus [BK virus; BKV]) infections are crucial factors involved in the incidence of chronic allograft dysfunction and graft failure. Renovascular lesions and lower urinary tract obstruction are typical indicators for surgical intervention. The aim of treatment in pediatric patients with renal failure secondary to a dysfunctional lower urinary tract is to create a sterile, continent, and nonrefluxive reservoir. Surgical techniques such as bladder augmentation and the introduction of intermittent catheterization and anticholinergic therapy have significantly improved graft outcome. Arterial hypertension, another factor responsible for graft function deterioration in pediatric renal transplant recipients, is controlled preferably by the use of angiotensin converting enzyme (ACE) inhibitors or angiotensin II receptor antagonists, which are known to possess nephroprotective properties in addition to their potent antihypertensive effects. Although treatment of subclinical rejection with augmented immunosuppression has been associated with better graft survival, an increase of the immunosuppressive level to avoid subclinical rejection should be weighed against the risk of infection. The majority of viral infections affecting kidney allografts are caused by CMV and BKV. Antiviral CMV prophylaxis or pre-emptive therapy with ganciclovir has been shown to have beneficial effects in the pediatric renal transplant population. Treatment of BKV-induced nephropathy is based on reduction of the immunosuppressant therapy, although specific antiviral agents such as cidofovir and leflunomide are known to inhibit BKV. However, cidofovir itself is nephrotoxic and should therefore be administered cautiously to pediatric renal transplant patients. Since CNIs are likewise known for their nephrotoxic effects, especially with long-term use, alteration of the immunosuppressant regimen is necessary in case of deteriorating graft function due to CNI-induced histopathologic changes. Complete CNI avoidance seems inappropriate because, in this situation in pediatric renal transplant recipients, other relatively potent immunosuppressant agents such as lymphocyte-depleting antibodies, which are frequently accompanied by a higher incidence of infections, are needed for rejection prophylaxis. CNI withdrawal and switching of the immunosuppressant regimen from CNI therapy to sirolimus may be an option for some pediatric renal transplant patients with less advanced graft function deterioration. Nevertheless, potential adverse events such as aggravation of proteinuria, hyperlipidemia, myelosuppression, and hypergonadotropic hypogonadism have to be considered, and controlled studies are lacking. At present, an immunosuppressant maintenance therapy composed of low-dose tacrolimus or ciclosporin (CNI minimization) and mycophenolate mofetil with low-dose corticosteroids appears to be the most promising strategy to adopt in pediatric renal transplant recipients at low or normal immunologic risk.

The active metabolite of the novel immunosuppressive agent leflunomide has been shown to inhibit the enzyme dihydroorotate dehydrogenase (DHODH). This enzyme catalyzes the fourth step in de novo pyrimidine biosynthesis. Self-organizing molecular field analysis (SOMFA), a simple three-dimensional quantitative structure-activity relationship (3D-QSAR) method is used to study the correlation between the molecular properties and the biological activities of a series of analogues of the active metabolite. The statistical results, cross-validated r(CV) (2) (0.664) and non cross-validated r(2) (0.687), show a good predictive ability. The final SOMFA model provides a better understanding of DHODH inhibitor-enzyme interactions, and may be useful for further modification and improvement of inhibitors of this important enzyme.

The literature search identified 32 articles for MTX, 12 for LEF (resulting in 34 case reports), 3 for gold, 1 for AZA, 4 for SSZ, 27 for TNFi (resulting in 31 case reports), 3 for RTX, 5 for TCZ (resulting in 8 case reports), and 1 for ABA. No case was found for HCQ or anakinra. Common points are noted between LEF- and TNFi-related ILD in RA: ILD is a rare severe adverse event, mostly occurs within the first 20 weeks after initiation of therapy, causes dyspnea mostly in older patients, and can be fatal. Although no definitive causative relationship can be drawn from case reports and observational studies, these data argue for a pulmonary follow-up in RA patients with pre-existing ILD, while receiving biologic therapy or nbDMARDs.

Since 2003, a new viral disease of eggplant (Solanum melongena L.) has been spreading in fields in the Jordan and Arava Valleys, Israel. The symptoms of this disease include mild leaf mottling and varying degrees of fruit distortion. This disease can be transmitted by mechanical sap inoculation, as well as by the whitefly Bemisia tabaci (Homoptera, Aleyrodidae) and has been tentatively named eggplant mild leaf mottle virus (EMLMV). Our study aimed to determine the complete sequence and genome organization of EMLMV. The extracted viral RNA was subjected to SOLiD next-generation sequence analysis and used as a template for reverse transcription synthesis, which was followed by ds-cDNA synthesis or PCR amplification. The ssRNA genome of EMLMV includes 9,280 nucleotides, excluding a 3' terminal poly-adenylated tail. The genome includes a putative single, large open reading frame (ORF) that encodes a polyprotein of 3,011 amino acids, a short overlapping ORF of PIPO protein comprised of 71 amino acids and 5' and 3' non-coding regions of 108 and 136 nucleotides, respectively. The deduced amino acid sequence of the EMLMV polyprotein is relatively close to that of sweet potato mild mottle virus (SPMMV), with 37% shared sequence identity. Among the four ipomoviruses, only SPMMV and the putative genus member EMLMV contain a helper component-proteinase (HC-Pro) gene. Like SPMMV-HC-Pro, EMLMV-HC-Pro also contains the highly conserved PTK domain that is thought to be involved in the aphid-assisted transmission of potyviruses.

Rheumatoid arthritis (RA) is a chronic immune-mediated disease characterised by chronic synovitis, which leads to cartilage damage and joint destruction. It is generally a progressive disease with radiographic evidence of joint damage, functional status decline and premature mortality. Proinflammatory cytokines, such as interleukin 1 and tumour necrosis factor alpha, play an important role in maintaining the chronicity of RA and mediating tissue damage. New approaches in the therapy of RA with anticytokine biological agents, which neutralise or block cytokines or their receptors, are now the first generation antirheumatic drugs in clinical practice. A better understanding of the signal transduction systems and gene regulation by transcription factors involved in cytokine production has opened the way for the discovery of novel therapeutic compounds useful in treating patients with RA. Overactivation of selective kinases or aberrant function of downstream transcription factors could help convert a normal immune response to a chronic disease state. This provides a unique opportunity for novel therapeutic interventions, since specific signal transduction or transcription factor targets might interrupt the perpetuation mechanisms in RA. The availability of potent and selective p38 mitogen activated protein kinase inhibitors provide a means in further dissecting the pathways implicated in cytokine production, which in turn maintain the chronicity of RA. Many studies conclude that these compounds are very useful in the treatment of chronic synovitis and therefore are very promising for RA treatment.

Bruton's tyrosine kinase (BTK) is a member of the Src-related Tec family of protein tyrosine kinases. Mutations in the btk gene have been linked to severe developmental blocks in human B-cell ontogeny leading to X-linked agammaglobulinemia. Here, we provide unique biochemical and genetic evidence that BTK is an inhibitor of the Fas/APO-1 death-inducing signaling complex in B-lineage lymphoid cells. The Src homology 2, pleckstrin homology (PH), and kinase domains of BTK are all individually important and apparently indispensable, but not sufficient, for its function as a negative regulator of Fas-mediated apoptosis. BTK associates with Fas via its kinase and PH domains and prevents the FAS-FADD interaction, which is essential for the recruitment and activation of FLICE by Fas during the apoptotic signal. Fas-resistant DT-40 lymphoma B-cells rendered BTK-deficient through targeted disruption of the btk gene by homologous recombination knockout underwent apoptosis after Fas ligation, but wild-type DT-40 cells or BTK-deficient DT-40 cells reconstituted with wild-type human btk gene did not. Introduction of an Src homology 2 domain, a PH domain, or a kinase domain mutant human btk gene into BTK-deficient cells did not restore the resistance to Fas-mediated apoptosis. Introduction of wild-type BTK protein by electroporation rendered BTK-deficient DT-40 cells resistant to the apoptotic effects of Fas ligation. BTK-deficient RAMOS-1 human Burkitt's leukemia cells underwent apoptosis after Fas ligation, whereas BTK-positive NALM-6-UM1 human B-cell precursor leukemia cells expressing similar levels of Fas did not. Treatment of the anti-Fas-resistant NALM-6-UM1 cells with the leflunomide metabolite analog alpha-cyano-beta-methyl-beta-hydroxy-N-(2, 5-dibromophenyl)propenamide, a potent inhibitor of BTK, abrogated the BTK-Fas association without affecting the expression levels of BTK or Fas and rendered them sensitive to Fas-mediated apoptosis. The ability of BTK to inhibit the pro-apoptotic effects of Fas ligation prompts the hypothesis that apoptosis of developing B-cell precursors during normal B-cell ontogeny may be reciprocally regulated by Fas and BTK.

Beginning in 1998, a surge of new agents has expanded treatment options for rheumatoid arthritis (RA) patients. Although the disease modifying potential of these agents is encouraging, their use must be weighed against an evolving array of new safety concerns. Because of the popularity of these agents with patients and rheumatologists alike, clinicians must be prepared to discuss the potential risks associated with novel disease-modifying antirheumatic drugs and biologic therapies as they begin to appear with greater frequency in practice. This article discusses the safety issues arising from clinical trial and postmarketing experience with several new and commonly used agents, with specific emphasis on adalimumab, etanercept, infliximab, anakinra, and leflunomide.

The primary goal in the treatment of rheumatoid arthritis (RA) is to maintain good quality of life by preventing joint destruction and avoiding disability. For this purpose, all patients with the diagnosis of RA should be treated by disease-modifying antirheumatic drugs (DMARDs) including biologic DMARDs and non-biologic DMARDs. All DMARDs are expected to prevent the progression of bone and cartilage destruction of RA patients from the results of in vitro research, and prevention of joint destruction is confirmed in vivo in all biologic DMARDs, but not in all non-biologic DMARDs. In this chapter, we would like to review the results of basic researches and clinical studies to demonstrate the prevention of joint destruction by non-biologic DMARDs that have been frequently used I daily practice.

Oral administration of leflunomide was a safe and effective alternative to oral administration of corticosteroids for treatment of IMPA in dogs. On the basis of findings in this study, a starting dosage for leflunomide of 3 to 4 mg/kg (1.4 to 1.8 mg/lb) PO once daily for at least 6 weeks before making dose adjustments is recommended. Dose adjustments should be based on cytologic evaluation of synovial fluid and clinical signs of IMPA. Hematologic variables, serum biochemical analysis results, and clinical signs of IMPA should be monitored for evidence of adverse effects to treatment with leflunomide.

The renal toxicity of DMARDs varies widely. Cyclosporine, gold, and D-penicillamine all have a serious potential for renal side effects, particularly in the elderly or in patients with compromised renal function. Concomitant use of nonsteroidal anti-inflammatory drugs (NSAIDs) increases the potential for renal damage. In contrast, methotrexate, azathioprine, antimalarials, sulfasalazine, leflunomide, etanercept, and infliximab have relatively little renal toxicity.

Patients (n = 179) with relapsing-remitting MS (n = 157) or secondary progressive MS with relapses (n = 22) were randomized to receive placebo, teriflunomide 7 mg/day, or teriflunomide 14 mg/day for 36 weeks. MRI brain scans were performed every 6 weeks. The primary endpoint was the number of combined unique active lesions per MRI scan. Secondary endpoints included MRI-defined disease burden, relapse frequency, and disability increase.

The considerable progress in the treatment of RA over the past 20 years is due in large part to a better understanding of how to use DMARDs optimally and the introduction of biologic agents. In addition to their ability to suppress inflammation, and thereby reduce symptoms of pain and stiffness, these drugs also have the potential to alter the course of RA by slowing disease progression and reducing joint damage.

Significantly higher A77 buy arava 1726 concentrations were seen in patients with less swollen joints and with higher SF-36 mental summary scores than in those with measures indicating more active disease (P < 0.05); concentration-effect trends were seen with five other disease activity measures. Statistical analysis of all disease activity measures showed that mean A77 1726 concentrations in groups with greater control of disease activity were significantly higher than those in whom the measures indicated less desirable control (P < 0.05). There was large between subject variability in the dose-concentration relationship. A steady-state infusion model best described the pharmacokinetic data. Inclusion of age as a covariate decreased interindividual variability (P < 0.01), but this would not be clinically important in terms of dosage changes.

A case of fatal pulmonary Mycobacterium abscessus infection in a 56-year-old man is reported. The patient had a longstanding history of seropositive, nodular rheumatoid arthritis with severe joint manifestations that had been treated with a regimen of prednisone, leflunomide, and etanercept. He buy arava presented to our facility with complaint of productive cough, persistent fevers, pleuritic chest discomfort, and dyspnea at rest. The patient was admitted to hospital, placed in isolation, a left-sided chest tube was inserted (left pneumothorax identified), and sputum acid-fast bacteria stains and cultures were obtained. Fluorochrome stains demonstrated numerous acid-fast bacteria, and M. abscessus was recovered from the culture media. He was treated with a regimen of amikacin, cefoxitin, and clarithromycin. He initially responded well, and was discharged home with this regimen. He remained afebrile with decreased cough and sputum production until 15 days after discharge when he was again admitted to hospital, with acute onset dyspnea and right-sided chest discomfort (right pneumothorax identified). He ultimately expired, due to overwhelming pulmonary infection, 20 days after readmission to hospital. Autopsy revealed acid fast bacilli in the setting of numerous, bilateral, necrotic, granulomatous, cavitary pulmonary lesions. Based on its mechanism of action, we propose an association between the use of etanercept, a tumor necrosis factor alpha (TNF-alpha) inhibitor, and this case of fatal pulmonary mycobacterial infection. We recommend that physicians exercise cautious clinical judgment when initiating etanercept therapy in persons with underlying lung disease, especially in communities in which mycobacterial organisms are highly prevalent. We also advise physicians to maintain a high level of vigilance for late onset granulomatous infection in persons using etanercept.

Leflunomide (Arava) has recently been approved by the Food and Drug Administration for the treatment of rheumatoid arthritis (RA). The drug, due to its protective effects on structural joint damage, has been classified as a disease modifying anti-rheumatic drug (DMARD). Leflunomide is structurally dissimilar from other drugs currently used to treat RA and exhibits a different mechanism of action. It has shown to be protective in a variety buy arava of animal models of arthritis and autoimmunity based on its immunomodulatory activity. Leflunomide is rapidly converted in vivo to its pharmacologically active metabolite A77 1726. This metabolite is a potent non-cytotoxic inhibitor of the enzyme dihydroorotate dehydrogenase (DHODH), a key enzyme in the de novo synthesis of uridine monophosphate (UMP). Activated lymphocytes depend on the pyrimidine de novo syntheses to fulfill their metabolic needs for clonal expansion and terminal differentiation into effector cells. De novo synthesis of pyrimidines is not only essential to provide precursors for new RNA and DNA synthesis, but also for phospholipid synthesis and the pyrimidine sugars necessary for protein glycosylation, which support the massive expansion in membrane biosynthesis to form daughter cells. This mechanism likely contributes to leflunomide's action as a DMARD in RA and other autoimmune diseases. This review is a summary of current in vivo and in vitro data, focussing primarily on the mechanism of action of leflunomide in RA.

Heart transplants were performed in rats (Brown Norway [BN] to Lewis) and treated with varying doses of FK778 or leflunomide for 28 days. At 28 days, at the time of rejection or at the death of the animal, the allograft and other vital organs were obtained for study by light microscopy and Diflucan 100 Mg immunohistochemistry. In separate experiments, Lewis rats were given sublethal irradiation, inoculated with rat CMV (Maastricht strain), and treated with varying doses of FK778 and leflunomide. In both the transplant and CMV studies, IP uridine was given at 250 mg/kg to cohorts or animals receiving FK778 and leflunomide.

We treated twenty-six patients with biopsy proven NK virus nephropathy (BKN) with either leflunomide alone (n=17) or leflunomide plus a course of cidofovir (n=9) and followed them for six to forty months. Leflunomide was dosed to a targeted blood level Ceftin Oral Suspension of active metabolite, A77 1726, of 50 microg/ml to 100 microg/ml (150 microM to 300 microM). Response to treatment was gauged by serial determinations of viral load in blood and urine (PCR), serum creatinine, and repeat allograft biopsy.

BK virus nephropathy was reported in 25 (4.6%) of 542 patients at a median onset of 10.1 mo after transplantation. The median age was 11 yr. All patients who were tested reported BK viruria, and 19 (91%) of 21 who had plasma tested reported BK viremia. Treatment of BK virus nephropathy included reduction of immunosuppression (84%), cidofovir (24%), leflunomide (8%), and intravenous Ig (20%). Simultaneous rejection treatment was reported in four (16%). The median creatinine Bactrim Dosing Obesity was 2.0 mg/dl at a mean follow-up of 24 mo. There were six (24%) graft failures in the patients with BK virus nephropathy at a mean of 24 mo after diagnosis. Rejection occurred in eight (32%) after diagnosis. Multivariate analysis showed that use of polyclonal induction therapy and zero HLA DR mismatch were associated with the development of BK virus nephropathy.

The recommendations were based on evidence from the literature. First, a scientific committee used a Delphi procedure to select five focal points of interest. Then, a literature task force looked for relevant publications in the following: Cochrane, Pubmed, and Ovid databases and abstracts from the French Society for Rheumatology, European League against Rheumatism and American College of Rheumatology. Based on the data from these publications, recommendations were drafted and then validated by a group of 68 experts. The strength of each recommendation was determined, as well as the extent of agreement among the experts.

Relatively elevated concentrations of naturally occurring radium isotopes ((226)Ra, (228)Ra and (224)Ra) are found in two main aquifers in the arid southern part of Israel, in activity concentrations frequently exceeding the limits set in the drinking water quality regulations. We aimed to explore the environmental implications of using water containing Ra for irrigation. Several crops (cucumbers, melons, radish, lettuce, alfalfa and wheat), grown in weighing lysimeters were irrigated at 3 levels of (226)Ra activity concentration: Low Radium Water (LRW)<0.04 Bq L(-1); High Radium Water (HRW) at 1.8 Bq L(-1) and (3) Radium Enriched Water (REW) at 50 times the concentration in HRW. The HYDRUS 1-D software package was used to simulate the long-term (226)Ra distribution in a soil irrigated with HRW for 15 years. Radium uptake by plants was found to be controlled by its activity in the irrigation water and in the soil solution, the physical properties of the soil and the potential evapotranspiration. The (226)Ra apeared to accumulate mainly in the leaves of crops following the evapotranspiration current, while its accumulation in the edible parts (fruits and roots) was minimal. The simulation of 15 years of crop irrigation by HYDERUS 1-D, showed a low Ra activity concentration in the soil solution of the root zone and a limited downward mobility. It was therefore concluded that the crops investigated in this study can be irrigated with the natural occurring activity concentration of (226)Ra of 0.6-1.6 Bq L(-1). This should be accompanied by a continuous monitoring of radium in the edible parts of the crops.
