#1
Gokhan Keser, Kenan Aksu
Management of Takayasu arteritis (TAK) is challenging mostly due to difficulties in assessing actual disease activity. The rational of medical treatment is to suppress both vascular and systemic inflammation with appropriate systemic immunosuppression, including corticosteroids and conventional immunosuppressive (IS) agents. In case of refractory disease activity, biologic agents such as TNF inhibitors and tocilizumab may be tried. In selected cases, endovascular interventions and surgical procedures may be indicated and should be performed during inactive disease...

Malignant melanoma (MM) is one of the most malignant tumors and has a very poor prognosis. However, there are no effective drugs to treat this disease. As a kind of iron flavin dependent enzyme, dihydroorotate dehydrogenase (DHODH, EC 1.3.3.1) is the fourth and a key enzyme in the de novo biosynthesis of pyrimidines. Herein, we found that DHODH inactivation/deficiency inhibited melanoma cell proliferation, induced cell cycle arrest at S phase and lead to autophagy in human melanoma cells. Meanwhile, leflunomide treatment induced cell apoptosis and deficiency of DHODH sensitized cells to drug-induced apoptosis in BCL-2 deficient melanoma cells, while not in BCL-2 abundant melanoma cells...

BACKGROUND: Delayed xenograft rejection (DXR) is an insurmountable barrier for xenotransplantation. Previous studies reported that hamster hearts transplanted into rats undergo DXR and stop functioning after the cessation of immunosuppression. Herein, we investigated the effects of resveratrol on preventing DXR in a hamster-to-rat vascularized cardiac xenograft model. METHODS: Hamster hearts were engrafted into Lewis rat recipients. Recipient rats received a graft acceptance-inducing treatment of leflunomide and FK506 for 2 weeks to prevent acute xenograft rejection (AXR)...

BACKGROUND: The standard dose of rituximab used in rheumatoid arthritis (RA) is 1000 mg but recent studies have shown that low dose (500 mg) is also effective. Efficacy of low dose rituximab in rheumatoid arthritis (RA) refractory to first-line non-biologic Disease Modifying Anti Rheumatic Drugs (DMARDs), compared to leflunomide is unknown. In a tertiary care referral setting, we conducted a randomized, double blind controlled clinical trial comparing the efficacy and safety of low-dose rituximab-methotrexate combination with leflunomide-methotrexate combination...

BK viras is a human polyoma viras. It is acquired in early childhood and remains life-long latent in the genitourinary system. BK virus replication is more common in receiving immunosuppressive therapy receiving patients and transplant patients. BK virus could cause hemorrhagic cystitis in patients with allogeneic stem cell transplantation. Hemorrhagic cystitis is a serious complication of hematopoietic stem cell transplantation. Hemorrhagic cystitis could cause morbidity and long stay in the hospital. Diagnosis is more frequently determined by the presence of BK virus DNA detected with quantitative or real-time PCR testing in serum or plasma and less often in urine...

Ganciclovir-resistant cytomegalovirus (GR-CMV) is emerging as a significant infection in the abdominal transplant population. GR-CMV is difficult to manage, and treatment options are limited. We report a descriptive case series of 15 patients who had documented GR-CMV at our center and review the literature on treatment of GR-CMV. The first case in this series was detected in 2012; the majority of cases occurred after January 1, 2014, with approximately 50% occurring in 2015. UL97 and UL54 viral genome mutations were present in 100% and 40% of CMV-infected patients, respectively...

Human metabolomics has great potential in disease mechanism understanding, early diagnosis, and therapy. Existing metabolomics studies are often based on profiling patient biofluids and tissue samples and are difficult owing to the challenges of sample collection and data processing. Here, we report an alternative approach and developed a computation-based prediction system, MetabolitePredict, for disease metabolomics biomarker prediction. We applied MetabolitePredict to identify metabolite biomarkers and metabolite targeting therapies for rheumatoid arthritis (RA), a last-lasting complex disease with multiple genetic and environmental factors involved...

EBV infection causes mononucleosis and is associated with specific subsets of B cell lymphomas. Immunosuppressed patients such as organ transplant recipients are particularly susceptible to EBV-induced lymphoproliferative disease (LPD), which can be fatal. Leflunomide (a drug used to treat rheumatoid arthritis) and its active metabolite teriflunomide (used to treat multiple sclerosis) inhibit de novo pyrimidine synthesis by targeting the cellular dihydroorotate dehydrogenase, thereby decreasing T cell proliferation...

Leflunomide is indicated for the treatment of adults with rheumatoid arthritis, yet is underutilized. Given the cost of biologic therapy, understanding real-life effectiveness, safety, and sustainability of leflunomide, particularly in patients who have failed methotrexate, would be of value. The primary objective was to assess the proportion of patients achieving clinically meaningful benefit following an adequate trial of leflunomide. A retrospective analysis of a cohort supplemented with patient self-reported data using a standardized questionnaire...

We present the case of a 12-year-old-girl who developed lichenoid dermatitis approximately 1 year after starting leflunomide for juvenile idiopathic arthritis. The eruption resolved promptly with discontinuation of the suspected culprit agent, supportive of a lichenoid drug eruption, but she subsequently developed markedly dystrophic nails with lichen planus-like features. A biopsy of her cutaneous findings at the time of initial presentation demonstrated lichenoid dermatitis, and a nail matrix biopsy was deferred given clinical correlation...
