Introduction: Systemic sclerosis is a complex disease that affects various target organs, making it difficult to assess response and determine remission or relapse. A baseline Neutrophil-to-Lymphocyte Ratio (NLR) >2.95 is associated with severe progressive skin and lung disease and decreased 5-year survival in systemic sclerosis (SSc).

CYC, however, does not provide a long-term benefit in SSc. The combination of MMF and rituximab is a potent alternative regimen.

Giant cell arteritis (GCA) is the most prevalent subtype of vasculitis in adults. In recent years, there has been substantial improvement in the diagnosis and treatment of GCA, mainly attributed to the introduction of highly sensitive diagnostic tools, incorporation of modern imaging modalities for diagnosis and monitoring of large-vessel vasculitis, and introduction of highly effective novel biological therapies that have revolutionized the field of GCA. This article reviews state-of-the-art approaches for the diagnosis, monitoring, and treatment options of GCA.

Aim: To characterize NVC changes in vasculitis.
Background: Autologous hematological stem cell transplantation (HSCT) is a novel therapy for systemic sclerosis (SSc) that has been validated in three randomized controlled trials.
Objectives: To report the first Israeli experience with HSCT for progressive SSc and review the current literature.
Methods: Five SSc patients who were evaluated in our department and were treated by HSCT were included.
Objective: Crowned dens syndrome (CDS) is defined as acute cervical or occipital pain due to a local inflammatory reaction related to calcifications in the ligaments surrounding the odontoid process. Virtually, all previous descriptions of CDS have related to calcium pyrophosphate dehydrate (CPPD) arthropathy.
Methods: We prospectively identified a total of twenty-four consecutive inpatients with Crowned dens syndrome from January 2016 to December 2017 in our institution.
Anakinra is a biological drug used in rheumatoid arthritis and several autoinflammatory diseases. Its main side effects are injection site reactions and increased infection rate. We present a 28-year-old man with familial Mediterranean fever, whose disease went into remission on anakinra, with concomitant flare of his ulcerative colitis.

Cyclophosphamide, a drug with narrow therapeutic range and poor safety profile, constitutes the treatment of choice for PAN vasculitis with major organ involvement. To describe our clinical experience in treating refractory PAN with infliximab (a TNF inhibitor), a drug with good tolerability and better safety profile than cyclophosphamide.

LOX was found to be increased in serum of SSc patients and was suggested to be related to skin fibrosis, yet a vascular source of LOX has been demonstrated in idiopathic pulmonary arterial hypertension (iPAH). We aimed to validate elevated LOX serum levels in SSc and to study its correlation with clinical characteristics and investigate its main source at the tissue level.

The semaphorins were first recognized for their important role in neurodevelopment and specifically their repulsive axonal growth guidance during embryonic development. Recently, semaphorins have also been found to have an important role in the regulation of the immune system, thus denoted as "immune semaphorins".

However, limited data in the literature suggests that rituximab may have the same efficacy profile whether used in combination with MTX or as monotherapy. The aim of our study is to compare the sustainability of rituximab as monotherapy to combined therapy with MTX or LEF in Israeli patients with RA.

Sacroiliitis, inflammation of the sacroiliac joint (SIJ), is the hallmark of ankylosing spondylitis and spondyloarthritis (SpA) in general. The arsenal of recommended diagnostic modalities for imaging of the SIJ is scanty and, in practice, includes only conventional X-rays and magnetic resonance imaging (MRI). This review suggests that bone scintigraphy, particularly single-photon emission computed tomography (SPECT) with calculation of indices, or SPECT in combination with low-dose computed tomography (CT) can be a sensitive and specific tool for the diagnosis of sacroiliitis and can be used as part of the individualized approach to the diagnosis of axial SpA.

Methods: 17 FMF patients during attack and then in remission, 8 FMF patients with smoldering disease and 12 healthy controls were enrolled.

Q fever is a zoonotic bacterial disease caused by Coxiella burnetii. Tumor necrosis factor-alpha (TNF-α) plays a pivotal role in the defense against infection with this Gram-negative coccobacillus. Theoretically, patients who are treated with anti-TNF-α medications are at risk for developing chronic Q fever.
View Article and Find Full Text PDFAutoinflammatory diseases are characterized by recurrent episodes of fever and localized or systemic inflammation and are caused by monogenic defects of innate immunity. The skin is commonly involved with various manifestations including erysipelas like rash and urticaria. Although vasculitis has been described in many autoinflammatory diseases, it has not been recognized as a characteristic feature of these diseases and autoinflammatory diseases are not listed as an etiology for vasculitis associated with a systemic disease in the 2012 Revised International Chapel Hill Consensus Conference Nomenclature of Vasculitides.

Case Report: We present a case of a 48-year-old male, diagnosed with chronic Lyme arthritis, refractory to recurrent and prolonged courses of doxycycline, ceftriaxone, as well as hydroxychloroquine and methotrexate. The patient responded partially to tumor necrosis factor (TNF)-alpha blockade by etanercept and, finally, entered long-term remission after his treatment was switched to tocilizumab.
Introduction: Thromboangiitis obliterans is an inflammatory occlusive vascular disease of young smokers that commonly involves the small and medium sized arteries and veins of the extremities. An important differential diagnosis of thromboangiitis obliterans is atherosclerotic arterial disease. An atypical presentation of thromboangiitis obliterans by involvement of mesenteric arteries has been described sporadically.

A Pubmed search utilizing the indexing term "acute sacroiliitis" was conducted and the data pertinent to the aim of the review was extracted and organized in accordance with the preplanned structure of the manuscript. The diagnosis of acute sacroiliitis is often challenging because of both the relative rarity of this presentation and diverse character of acute sacroiliac pain, frequently mimicking other, more prevalent disorders.
