Neutrophil-to-Lymphocyte Ratio as a Biomarker for Clinical Response After Autologous Hematopoietic Stem Cell Transplantation in Systemic Sclerosis.

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).

Outcomes in progressive systemic sclerosis treated with autologous hematopoietic stem cell transplantation compared with combination therapy.

Objectives: Autologous hematopoietic stem cell transplantation (AHSCT) has been shown to improve long-term survival for early diffuse progressive SSc compared with CYC. 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: State of the Art in Diagnosis, Monitoring, and Treatment.

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.

Nailfold video capillaroscopy as a useful diagnostic tool in systemic vasculitis.

Background: Nailfold video capillaroscopy (NVC) enables us a direct view of the microvasculature. Only several capillaroscopy studies in adult patients with vasculitis have been reported.

Aim: To characterize NVC changes in vasculitis.

The association between elevated serum interleukin-22 and the clinical diagnosis of axial spondyloarthritis: A retrospective study.

Objective: There is an unmet need for a reliable biomarker for the differentiation of axial spondyloarthritis (AxSpA) from its mimickers. Serum levels of interleukin-22 (IL-22) have previously been found to be significantly elevated in patients with AxSpA compared with healthy individuals or persons with osteoarthritis.

Methods: Consecutive patients with established or suspected AxSpA were enrolled.

Crowned dens syndrome, yet another rheumatic disease imposter.

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.

Ulcerative Colitis and Familial Mediterranean Fever: Can Anakinra Treat Both?

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.

Infliximab for the treatment of refractory polyarteritis nodosa.

Polyarteritis nodosa (PAN) is a necrotizing vasculitis predominantly affecting medium and small size arteries. 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.

Lysyl oxidase-a possible role in systemic sclerosis-associated pulmonary hypertension: a multicentre study.

Objective: Lysyl oxidase (LOX) is an extracellular enzyme that cross-links collagen fibrils. 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.

Ankylosing Spondylitis and Neck Pain: MRI Evidence for Joint and Entheses Inflammation at the Craniocervial Junction.

Background: Magnetic resonance imaging (MRI), which has recently become the leading imaging modality in the study of ankylosing spondylitis (AS), has not been evaluated in the assessment of disease-specific changes at the craniocervical junction (CCJ) in patients with AS.

Objectives: To describe the spectrum of active inflammatory lesions at the CCJ using MRI in a cohort of patients with AS and neck pain.

Methods: The study included 18 patients with AS presenting with neck pain and a control group of 9 fibromyalgia patients matched for age and levels of neck pain.

[THE ROLE OF SEMAPHORIN 7A IN SYSTEMIC SCLEROSIS].

Introduction: Semaphorins are a large group of membrane bound and secreted proteins. 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".

Autoinflammatory associated vasculitis.

Autoinflammatory 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.
