CD28 Signaling Controls Metabolic Fitness of Pathogenic T Cells in Medium and Large Vessel Vasculitis.

J Am Coll Cardiol 2019 Apr;73(14):1811-1823

Department of Medicine, Division of Immunology and Rheumatology, Stanford University School of Medicine, Stanford, California. Electronic address:

Background: In giant cell arteritis, vessel-wall infiltrating CD4 T cells and macrophages form tissue-destructive granulomatous infiltrates, and the artery responds with a maladaptive response to injury, leading to intramural neoangiogenesis, intimal hyperplasia, and luminal occlusion. Lesion-residing T cells receive local signals, which represent potential therapeutic targets.

Objectives: The authors examined how CD28 signaling affects vasculitis induction and maintenance, and which pathogenic processes rely on CD28-mediated T-cell activation. Read More

Identification of an activated neutrophil phenotype in polymyalgia rheumatica during steroid treatment: a potential involvement of immune cell cross-talk.

Clin Sci (Lond) 2019 Apr 4;133(7):839-851. Epub 2019 Apr 4.

Department of Biochemical Pharmacology, William Harvey Research Institute, Barts and the London School of Medicine, Queen Mary University of London, U.K.

We have reported the existence of a distinct neutrophil phenotype in giant cell arteritis (GCA) patients arising at week 24 of steroid treatment. In the present study, we investigated whether longitudinal analysis of neutrophil phenotype in patients with polymyalgia rheumatica (PMR) could reveal a novel association with disease status and immune cell cross-talk. Thus, we monitored PMR patient neutrophil phenotype and plasma microvesicle (MV) profiles in blood aliquots collected pre-steroid, and then at weeks 1, 4, 12 and 24 post-steroid treatment. Read More

Is it required to routinely check fibrinogen level in patients with rheumatic diseases on tocilizumab? Case-based review.

Rheumatol Int 2019 Apr 14;39(4):743-750. Epub 2019 Mar 14.

Division of Rheumatology, Department of Internal Medicine, Eskişehir Osmangazi University, Eskisehir, Turkey.

Tocilizumab (TCZ) may rarely cause hematological side effects including neutropenia and thrombocytopenia. TCZ is essentially expected to lower the fibrinogen levels to stay within the normal range, but TCZ-induced hypofibrinogenemia has been rarely reported in literature. Although it may remain asymptomatic, hypofibrinogenemia has clinical significance owing to the tendency of the condition to result in bleeding. Read More

BMJ Case Rep 2019 Mar 6;12(3). Epub 2019 Mar 6.

Vasculitis, Cambridge University Hospitals NHS Foundation Trust, Cambridge, UK.

Giant cell arteritis (GCA) is the most common vasculitis in adults and blindness is a common complication if left untreated. Oral glucocorticoids are the mainstay of treatment and if started promptly, loss of vision can usually be prevented. We present the case of a 77-year-old man who developed irreversible bilateral blindness after a confirmed diagnosis of GCA and oral steroid treatment. Read More

Varicella Zoster Virus Alters Expression of Cell Adhesion Proteins in Human Perineurial Cells Via Interleukin 6.

J Infect Dis 2019 Mar 5. Epub 2019 Mar 5.

Department of Neurology, University of Colorado School of Medicine, Aurora.

Background: In temporal arteries (TAs) from giant cell arteritis patients, varicella zoster virus (VZV) is seen in perineurial cells that surround adventitial nerve bundles and form the peripheral nerve-extrafascicular tissue barrier (perineurium). We hypothesized that during VZV reactivation from ganglia, virus travels transaxonally and disrupts the perineurium to infect surrounding cells.

Methods: Mock- and VZV-infected primary human perineurial cells (HPNCs) were examined for alterations in claudin-1, E-cadherin and N-cadherin. Read More

Nuclear Medicine Unit, Oncology and Advanced Technologies Department, Azienda Unità Sanitaria Locale-IRCCS di Reggio Emilia, 42123, Reggio Emilia, Italy.

MiRNAs are single stranded RNAs of 18-22 nucleotides. They are promising diagnostic and prognostic markers for several pathologies including tumors, neurodegenerative, cardiovascular and autoimmune diseases. In the present work the development and characterization of anti-miRNA radiolabeled probes based on peptide nucleic acids (PNAs) for potential non-invasive molecular imaging in vivo of giant cell arteritis are described.

[Effectiveness of a Low-dose Corticosteroid in a Patient with Polymyalgia Rheumatica Associated with Nivolumab Treatment].

Yakugaku Zasshi 2019 ;139(3):491-495

Department of Hospital Pharmacy, Kansai Medical University.

Nivolumab, an anti-programmed cell death 1 antibody, has been approved for the treatment of unresectable advanced non-small-cell lung cancer (NSCLC). Although immune-related adverse events (irAEs) such as dermatologic, digestive, endocrine, hepatic, and pulmonary toxicities are known to occur upon administration of immune checkpoint inhibitors, case reports of polymyalgia rheumatica (PMR) associated with nivolumab use are rare. We report a case of an NSCLC patient who developed PMR during treatment with nivolumab and received corticosteroids. Read More

Giant Cell Arteritis (GCA): Pathogenesis, Clinical Aspects and Treatment Approaches.

Curr Rheumatol Rev 2019 Feb 27. Epub 2019 Feb 27.

Otorhinolaryngology Department, Sapienza University of Rome, Policlinico Umberto I, Viale del Policlinico,151 - 00161, Rome, . Italy.

Giant Cell Arteritis (GCA), or Horton's Arteritis, is a chronic form of vasculitis of the large and medium vessels, especially involving the extracranial branches of the carotid arteries, in particular, the temporal artery, with the involvement of the axillary, femoral and iliac arteries too. Arterial wall inflammation leads to luminal occlusion and tissue ischemia, which is responsible for the clinical manifestations of the disease. A substantial number of patients affected by GCA present head and neck symptoms, including ocular, neurological and otorhinolaryngological manifestations. Read More

Picturing Giant Cell Arteritis: Projecting Into the Future.

Arthritis Rheumatol 2019 Mar 2. Epub 2019 Mar 2.

Brigham and Women's Hospital, Boston, Massachusetts, United States.

Imaging now plays an important role in the evaluation of giant cell arteritis (GCA). A growing body of literature supports the use of ultrasound, CT, MRI and PET to assist with diagnosis. EULAR recently recommended ultrasound or high-resolution MRI as diagnostic tests for GCA involving the superficial cranial arteries; ultrasound, MRI, CT, and PET are recommended for evaluating large arteries, with the caveat that ultrasound has limited value for detecting aortitis.

Reviewing the Pathophysiology Behind the Advances in the Management of Giant Cell Arteritis.

Ophthalmol Ther 2019 Mar 1. Epub 2019 Mar 1.

Birmingham Neuro-Ophthalmology, Queen Elizabeth Hospital, University Hospitals Birmingham, Birmingham, B15 2WB, UK.

Improving understanding of the underlying pathophysiology of giant cell arteritis (GCA) is transforming clinical management by identifying novel avenues for targeted therapies. One key area of concern for both clinicians and patients with GCA is glucocorticoid (GC) morbidity. The first randomised controlled trials of targeted treatment to reduce cumulative GC use in GCA have been published, with tocilizumab, an interleukin (IL)-6 receptor inhibitor, now the first ever licensed treatment for GCA.

The Platelet-to-Lymphocyte Ratio as an Inflammatory Marker in Rheumatic Diseases.

Ann Lab Med 2019 Jul;39(4):345-357

Departments of Rheumatology and Research and Development, Dudley Group NHS Foundation Trust (Teaching Trust of the University of Birmingham, UK), Russells Hall Hospital, Dudley, West Midlands, UK.

The platelet-to-lymphocyte ratio (PLR) has emerged as an informative marker revealing shifts in platelet and lymphocyte counts due to acute inflammatory and prothrombotic states. PLR has been extensively examined in neoplastic diseases accompanied by immune suppression and thrombosis, which can be predicted by combined blood cell counts and their ratios. Several large observational studies have demonstrated the value of shifts in PLR in evaluating the severity of systemic inflammation and predicting infections and other comorbidities, in inflammatory rheumatic diseases.
