PURPOSE: The primary cause of Cushing's disease is adrenocorticotropic hormone (ACTH)-producing pituitary adenomas. EGFR signaling induces POMC mRNA-transcript levels and ACTH secretion from corticotroph tumors. The Jak-STAT pathway is located downstream of EGFR signaling; therefore, a Jak2 inhibitor could be an effective therapy for EGFR-related tumors. In this study, we determined the effect of a potent and selective Jak2 inhibitor, SD1029, on ACTH production and proliferation in mouse AtT20 corticotroph tumor cells...

Takayasu arteritis, fibromuscular dysplasia (FMD), spontaneous arterial dissection, Raynaud's phenomenon, and chilblains are vascular conditions that are associated with an increased predisposition in women and are often underdiagnosed. Takayasu arteritis has an incidence rate of 2.6 cases per million individuals per year in the USA and predominantly affects women of childbearing age. HLA-B5 genetic locus is linked with Takayasu arteritis susceptibility. Methods to determine active disease are limiting; currently utilized clinical and imaging findings and laboratory tests are of limited value for this purpose...

Introduction-patients: Takayasu arteritis may involve various parts of the aorta and its major branches. It leads to occlusive or aneurysmal disease of the vessel. It can be treated either with surgery or percutaneous intervention. We report a successful endovascular treatment of stenosis of the descending thoracic and abdominal aorta in a 19-year-old female. Methods-results-conclusions: Self-expandable nitinol stent was deployed and adequate opening of the aorta was obtained in this patient. Long-term durability of endovascular approach is a matter of debate...

INTRODUCTION: Takayasu arteritis (TA) is a rare systemic vasculitis that affects large vessels often resistant to treatment and associated with high morbidity and mortality. Treatment is defied by the relapsing nature of the disease and frequent adverse effects of corticosteroids and immunosuppressors, rendering failure of treatment in a significant portion of patients. Considering the low quantity and quality of published studies focusing on treatment of TA, synthesis and critical assessment of the available evidence is fundamental to establish recommendations for clinical practice...

Despite the progress in the last years on the field of vasculitides, there are several unmet needs regarding classification, disease activity assessment, predictors of flares and complications, and type of treatment for the different forms. The 1990 American College of Rheumatology (ACR) classification criteria currently used to define giant cell arteritis and Takayasu arteritis were designed to discriminate between different types of vasculitides but not to differentiate vasculitis from other disorders. Recently, efforts have been made to overcome the shortcomings of the ACR criteria...

Interstitial lung disease (ILD) is a serious and potentially fatal adverse event in lung cancer therapy. Nanoparticle albumin-bound paclitaxel (nab-PTX) is a novel, solvent-free formulation of paclitaxel (PTX). Although the incidence of nab-PTX-induced ILD is not clear, it is generally considered that this formulation presents a similar risk of developing ILD as PTX. Here, we report 3 patients who developed severe ILD following treatment with nab-PTX. We draw attention to the risk of developing drug-induced ILD following nab-PTX treatment, and highlight that this novel formulation might therefore not be as safe as PTX with respect to the development of ILD...

Takayasu's arteritis is a rare systemic vasculitis mainly affecting the aorta and its major branches. Previous studies have suggested that almost half of the Asian Takayasu's patients have renal artery involvement. However, due to the rarity of the disease, little is known about renal artery involvement in Chinese Takayasu's arteritis patients. Here, we retrospectively reviewed and analyzed 411 patients diagnosed with Takayasu's arteritis in our center to explore the clinical features of renal artery involvement in this group of patients...

BACKGROUND: Aortitis is a rare condition with inflammatory or infectious etiology that can be difficult to diagnose due to the highly variable clinical presentation and nonspecific symptoms. However, current literature on the diagnosis, management, and prognosis of aortitis is extremely scarce. METHODS: We retrospectively reviewed all patients' charts who were diagnosed with giant cell arteritis, Takayasu arteritis, or noninfectious aortitis presenting at a single center between January 1, 2009, and April 17, 2015...

OBJECTIVE: Detection of epidermal growth factor receptor (EGFR) gene mutations is essential in deciding therapeutic strategy in non-small cell lung cancer (NSCLC) patients at initial diagnosis. Moreover, in EGFR mutation-positive (EGFRm) NSCLC patients, re-biopsy at disease progression to clarify resistance mechanisms is also important. However, collecting histology samples is often difficult because of inaccessibility and invasiveness. In some cases, only cytology samples can be collected, and studies have reported that cytology samples are appropriate for EGFR gene mutation testing...

Gitelman syndrome (GS) is an autosomal recessive, salt-losing renal tubulopathy caused by mutations in the SLC12A3 gene; however, it can also be acquired in patients with autoimmune disease, especially in those with Sjögren's syndrome. Differentiating between the inherited and acquired forms of GS is clinically difficult. We report a case of inherited, not acquired, GS in a patient with Sjögren's syndrome. A 41-year-old woman, who had been diagnosed with Sjögren's syndrome at 27-years-old, had shown chronic hypokalemia (2...

BACKGROUND: Several biomarkers have emerged as potential prognostic and predictive markers for non-small-cell lung cancer (NSCLC). Successful inhibition of angiogenesis with the antivascular endothelial growth factor antibody, bevacizumab, has improved the efficacy seen with standard cytotoxic therapy of NSCLC. However, despite such enhanced treatment strategies, the prognosis for patients with advanced NSCLC remains poor. PATIENTS AND METHODS: We assessed potential biomarkers in 161 NSCLC patients and 42 control patients...

Takayasu arteritis (TAK) is a vasculitis of the large arteries. The arterial wall, target of the immune reaction, is composed of vascular dendritic cells, endothelial cells, vascular smooth muscle cells and fibroblasts, which engage in an interaction with T cells and macrophages to, ultimately, cause luminal stenosis or aneurysmal wall damage of the vessel. A multitude of cytokines have been identified to increase in case of TAK and to be linked to disease activity. A better understanding of the physiopathological pathways and mechanisms involved, might enable a more tailored therapeutic approach in TAK...
