BACKGROUND/OBJECTIVE: Takayasu arteritis (TA) is characterized by extensive aortic, large and midsize arterial wall inflammation. The aim of this study was to assess the morphological and elastic properties of the aorta and large arteries and the impact on left ventricular (LV) mechanics in children with TA. METHODS: Seven pediatric TA patients (6 female patients, 13.8 ± 3.2 years) were assessed with magnetic resonance imaging, vascular ultrasound, applanation tonometry, and echocardiography from February 2015 until July 2017 and compared with 7 age- and sex-matched controls...

Selective plasma exchange has been shown to be effective in various diseases, but no studies have assessed the benefits of daily treatment. We aimed to investigate the removal dynamics of immunoglobulins, fibrinogen, and factor XIII on three consecutive days in three patients. For mean processed plasma volumes of 1.06 × plasma volume, reductions of 79.6%, 49.3%, and 8.6% were seen for immunoglobulins G, A, and M, respectively. The reductions for fibrinogen and factor XIII were 18.4% and 13.0%, respectively...

Antimalarials have been an effective and safe treatment for autoimmune rheumatic diseases such as systemic lupus erythematosus for more than a hundred years. There are surprisingly few reports of hydroxychloroquine use in the systemic vasculitides. Hydroxychloroquine has antithrombotic, cardiovascular, antimicrobial and antineoplastic effects, making it a potentially valuable treatment for patients with systemic vasculitis who are at risk of infections, malignancy and thrombotic events. We report the successful use of hydroxychloroquine in patients with ANCA vasculitis, Henoch Schonlein purpura/IgA vasculitis, Takayasu's arteritis and polyarteritis nodosa...

Introduction: Accumulating evidence suggests that a large hospital volume (HV) is associated with favorable outcomes in various diseases or surgical procedures. The aim of this study is to clarify the correlation of HV and dialysis case volume (DCV) with in-hospital death in patients on maintenance dialysis. Methods: The study cohort was derived from the Diagnosis Procedure Combination database, a national inpatient database in Japan, from 2012 to 2014. We included 382,689 admissions of maintenance dialysis patients over the age of 20 years in the analysis...

The diagnosis of longus colli tendinitis (LCT) is sometimes challenging, especially when laboratory data show marked inflammation and neuroimaging studies do not indicate calcification within the tendon of the longus colli muscles. We herein report a case of LCT that presented with elevated inflammation parameters without calcification on imaging. Findings characteristic of LCT, such as prevertebral hyperintensity areas on T2-weighted images and no signs of purulent diseases, informed our diagnosis of LCT. Enhanced computed tomography and magnetic resonance imaging are useful procedures when diagnosing LCT after ruling out other critical purulent diseases...

INTRODUCTION: Takayasu aortitis is a well known yet rare form of large vessel vasculitis. Also known as pulseless disease, occlusive thromboaortopathy, and Martorell syndrome, is a chronic inflammatory aortitis. Vessel inflammation leads to wall thickening, fibrosis, stenosis, and thrombus formation. METHODS: A 64-year-old woman was referred to emergency for lack of pulse in the upper and lower limbs and changes in heart rate. AngioRMN revealed dissection of the ascending aorta while in PET, intense uptake of FDG-F18 involving ascending, crossa, descending thoracic and abdominal segments of the aorta, was evident urgent surgical correction occurred...

Isolated arteritis of the lower limb vessels is an extremely rare condition. The use of modern vascular imaging techniques substantially facilitates and accelerates the diagnostics. In the isolated lower limb arteritis, it is always necessary to exclude Takayasu's and giant-cell arteritis. We present the case of a female patient with an isolated lower extremity arteritis without any other symptoms of systemic vascular damage or systemic autoimmune disease. Immunosuppressive therapy is obligatory in this case...

Background First-line therapy for advanced non-small-cell lung cancer (NSCLC) that lacks targetable mutations is platinum-based chemotherapy. Among patients with a tumor proportion score for programmed death ligand 1 (PD-L1) of 50% or greater, pembrolizumab has replaced cytotoxic chemotherapy as the first-line treatment of choice. The addition of pembrolizumab to chemotherapy resulted in significantly higher rates of response and longer progression-free survival than chemotherapy alone in a phase 2 trial. Methods In this double-blind, phase 3 trial, we randomly assigned (in a 2:1 ratio) 616 patients with metastatic nonsquamous NSCLC without sensitizing EGFR or ALK mutations who had received no previous treatment for metastatic disease to receive pemetrexed and a platinum-based drug plus either 200 mg of pembrolizumab or placebo every 3 weeks for 4 cycles, followed by pembrolizumab or placebo for up to a total of 35 cycles plus pemetrexed maintenance therapy...

Rare autoimmune diseases are difficult to conduct researches in spite of present era with advanced scientific progress. Research using genetic approach is a promising way since genetic findings implicate causality of diseases. Still, there are multiple obstacles preventing genetic studies of rare diseases. Here, we list up the problems and propose solutions for them with detailed examples. The biggest problem is that it is difficult to collect a substantial number of DNA samples from patients with rare diseases...

Primary sclerosing cholangitis (PSC) is a liver disease known for its frequent concurrence with inflammatory bowel disease. Dysbiosis of the gut microbiota in PSC was reported in several studies, but the microbiological features of the salivary microbiota in PSC have not been established. Here we compared the salivary microbial communities of 24 pediatric-onset PSC patients, 16 age-matched ulcerative colitis (UC) patients, and 24 healthy controls (HCs) by analyzing the bacterial 16S rRNA gene sequence data...

Background: The results of recent trials have brought some confusion to the treatment strategy for renal artery stenosis (RAS). To evaluate the applicability of percutaneous transluminal renal angioplasty (PTRA) for RAS, we extracted the factors that may affect the effectiveness of PTRA from cases experienced at a hypertension center. Methods and Results: We retrospectively assessed the blood pressure (BP) lowering effects and renoprotective effects in 50 consecutive patients that had hemodynamically significant RAS and had undergone PTRA and stenting during 2001-2005...
