Disease-modifying antirheumatic drugs (DMARDs) have become essential treatments in the management of patients with inflammatory rheumatic diseases. Their use has resulted in a marked improvement of disease control and a limitation of joint damage, although some patients still require subsequent corrective or joint replacement surgery. Due to their immunosuppressive effects, some DMARDs are associated with an increased risk of infection. The aim of this review is to discuss the available literature on the management of DMARDs during the perioperative period, particularly in the case of orthopaedic surgery...

Data concerning the use of leflunomide -a drug approved for rheumatoid arthritis with in vitro anti-cytomegalovirus (CMV) activity- in lung transplant (LT) recipients are scarce. We performed a single center retrospective study including LT recipients who received leflunomide for CMV infection or as secondary prophylaxis after viremia clearance. We also conducted a full systematic PubMed search until June 30, 2017. We identified 5 LT recipients in our center, plus 7 patients reported in the literature. All patients had previously received ganciclovir (GCV) and foscarnet, with drug-induced adverse effects described in 6 recipients (50%)...

PURPOSE: The various antiviral treatment options in the management of BK virus (BKV) viremia and BKV-associated nephropathy (BKVAN) are reviewed. SUMMARY: Review of the PubMed database from 1990 to 2016 for all English language case series, cohort studies, and randomized controlled trials detailing antiviral treatment of BKV viremia or BKVAN in kidney transplant recipients returned only 16 published reports. The majority of these reports were based on small case series or protocol-based cohort studies, with no prospective head-to-head data and only modest benefit reported for cidofovir, leflunomide, i...

OBJECTIVES: Leflunomide is known to be embryotoxic and teratogenic in rodents. However, there is less evidence in humans. We quantified the risk of major congenital malformation (MCM), prematurity, low birth weight (LBW) and spontaneous abortion associated with leflunomide exposure during pregnancy in humans. METHODS: From a cohort of 289 688 pregnancies in Montreal, Quebec, Canada, from 1998 to 2015, first-trimester leflunomide exposure and other antirheumatic drug exposures were studied for their association with MCM and spontaneous abortions...

- Polymyalgia rheumatica (PMR) is an inflammatory rheumatic disorder in which inflammation markers, both erythrocyte sedimentation rate (ESR) and CRP values, are often elevated. However, a non-abnormal ESR or CRP value does not preclude the diagnosis.- PMR is an arbitrary diagnosis and presents both diagnostic and therapeutic challenges.- Imaging diagnostics, such as echography, MRI or FDG-PET/CT, may potentially be applied more frequently as a second-line investigation when there is doubt concerning the diagnosis...

Astilbin, a flavonoid compound, was isolated from the rhizome of Smilax glabra Roxb. (with red cross-section) grown in Guizhou Province, China. We accessed its effect and potential mechanism on attenuation of the inflammatory response in CFA-induced AA rats. Our results showed that daily oral administration of astilbin at 5.3 mg/kg reduced joint damage in the hind paw of AA rats. Accordingly, astilbin exhibited remarkable inhibitory effects on TNF-α, IL-1β, and IL-6 mRNA expression. Significant decrease of serum cytokine levels of TNF-α, IL-1β, and IL-6 was also observed in astilbin-treated AA rats compared to the vehicle-treated AA rats...

Teriflunomide is an oral therapy approved for relapsing forms of multiple sclerosis which has been shown to reduce relapse rate and disability progression. We report the case of a 54-year -old black woman with multiple sclerosis who developed follicular lymphoma after about 8 months of exposure to teriflunomide. Importantly, apart from age, the patient had none of the established risk factors for follicular lymphoma. Moreover, although this is the first published case of a lymphoma on teriflunomide, it is not the first confirmed case...

Lung cancer causes more than 150000 deaths annually in the United States alone, of which non-small cell lung cancer (NSCLC) accounts for 80%. Our studies demonstrated that NSCLC cells were sensitive to leflunomide and its metabolite teriflunomide, a FDA approved drug, which was a well-known immunomodulatory drug for relapsing multiple sclerosis (MS). In the present studies, we found first time that they displayed anti-tumor activity of NSCLC in vitro and in vivo. Potent anti-cancer effects in NSCLC in vitro, including inhibiting NSCLC cells viability, arresting cell cycle at the G0/G1 phase, inducing cell apoptosis, delaying and suppressing NSCLC cells colony-forming ability and cell motility, could be achieved with this agent...

Previous studies showed that downregulation of pyrimidine salvage underlies resistance against 5-azacytidine (AZA), indicating an important role for de novo pyrimidine synthesis in AZA resistance. Because de novo pyrimidine synthesis is inhibited by the immunomodulator teriflunomide and its pro-drug leflunomide, we examined the effect of combined treatment with AZA and teriflunomide on AZA resistance to develop a novel strategy to cancel and prevent AZA resistance. Teriflunomide markedly inhibited the growth of AZA-resistant human leukemia cell lines (R-U937 and R-HL-60) in comparison with their AZA-sensitive counterparts (U937 and HL-60)...

Leflunomide, an immunosuppressive drug approved for the treatment of patients with rheumatoid arthritis, exhibits many mechanisms which may affect the nociceptive processing. Therefore, the present study aimed to evaluate the effect induced by leflunomide on the mechanical allodynia in models of inflammatory and neuropathic pain in mice and investigate mechanisms mediating such effects. Per os (p.o.) administration of leflunomide (25, 50 or 100mg/kg) inhibited the inflammatory edema and mechanical allodynia induced by intraplantar carrageenan...

Oral squamous cell carcinoma (OSCC) is the most prevalent pathological cancer occurring in the head and neck area. Progress has previously been made regarding treatment strategies of OSCC, however the 5‑year survival rate of these patients is only 50%. The present study examined if leflunomide (LEF), a drug primarily used for the treatment of rheumatoid arthritis, exhibited antitumor effects in OSCC. The results demonstrated that LEF inhibited cell proliferation and blocked the cell cycle at the S phase in OSCC cells, with upregulation of cyclin A protein expression...

The store-operated calcium entry (SOCE) pathway is an important route for generating cytosolic Ca(2+) signals that regulate a diverse array of biological processes. Abnormal SOCE seem to underlie several diseases that notably include allergy, inflammation and cancer. Therefore, any modulator of this pathway is likely to have significant impact in cell biology under both normal and abnormal conditions. In this study, we screened the FDA-approved drug library for agents that share significant similarity in 3D shape and surface electrostatics with few, hitherto best known inhibitors of SOCE...

The introduction of biologic disease-modifying anti-rheumatic drugs (bDMARDs) has dramatically changed the management of rheumatoid arthritis (RA). However, in a real-life setting about 30-40% of bDMARD treated patients experience drug discontinuation because of either inefficacy or adverse events. According to international recommendations, to date the best strategy for managing first-line bDMARD failures has not been defined yet and available data (especially on TNF inhibitors [TNFis]) seem to drive toward a personalized approach for the individual patient...
