Advances in cutaneous vasculitis research and clinical care.

Ann Transl Med 2021 Mar;9(5):439

Departments of Dermatology and Medicine, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, USA.

Vasculitis is characterized by inflammation and destruction of blood vessels, resulting in downstream ischemic tissue damage. Diagnosis of vasculitis is a careful exercise in clinical-pathologic correlation, depending upon the clinical manifestations, organs involved, the size of affected blood vessels, imaging, and laboratory findings. While some vasculitis subtypes may be confined to the skin, serious internal organ involvement or underlying disease states may also occur. Read More

Systemic sclerosis (scleroderma): remaining challenges.

Ann Transl Med 2021 Mar;9(5):438

Department of Dermatology, University of California, San Francisco, San Francisco, CA 94115, USA.

Despite progress in treating internal organ involvement in systemic sclerosis (scleroderma) (SSc), such as pulmonary disease, effective treatments for the hallmark of the disease, cutaneous fibrosis, remain elusive. None of the disease-modifying antirheumatic drugs (DMARDS) have shown proven efficacy for SSc skin fibrosis, and there remain no FDA-approved medications, all of which are off-label, for cutaneous fibrosis in SSc. This review article will briefly summarize conventional therapies, biologics and hematopoietic stem cell transplants and select ongoing clinical trials in SSc. Read More

Polishing the crystal ball: mining multi-omics data in dermatomyositis.

Ann Transl Med 2021 Mar;9(5):435

Ronald O. Perelman Department of Dermatology, NYU Grossman School of Medicine, New York, NY, USA.

Precision medicine, which recognizes and upholds the uniqueness of each individual patient and the importance of discerning these inter-individual differences on a molecular scale in order to provide truly personalized medical care, is a revolutionary approach that relies on the discovery of clinically-relevant biomarkers derived from the massive amounts of data generated by epigenomic, genomic, transcriptomic, proteomic, microbiomic, and metabolomic studies, collectively known as multi-omics. If harnessed and mined appropriately with the help of ever-evolving computational and analytic methods, the collective data from omics studies has the potential to accelerate delivery of targeted medical treatment that maximizes benefit, minimizes harm, and eliminates the "fortune-telling" inextricably linked to the prevailing trial-and-error approach. For a disease such as dermatomyositis (DM), which is characterized by remarkable phenotypic heterogeneity and varying degrees of multi-organ involvement, an individualized approach that incorporates big data derived from multi-omics studies with the results of currently available serologic, histopathologic, radiologic, and electrophysiologic tests, and, most importantly, with clinical findings obtained from a thorough history and physical examination, has immense diagnostic, therapeutic, and prognostic value.

Thrombotic microangiopathies assessment: mind the complement.

Clin Kidney J 2021 Apr 6;14(4):1055-1066. Epub 2020 Nov 6.

Josep Carreras Leukaemia Research Institute, Hospital Clinic/University of Barcelona Campus, Barcelona, Spain.

When faced with microangiopathic haemolytic anaemia, thrombocytopenia and organ dysfunction, clinicians should suspect thrombotic microangiopathy (TMA). The endothelial damage that leads to this histological lesion can be triggered by several conditions or diseases, hindering an early diagnosis and aetiological treatment. However, due to systemic involvement in TMA and its low incidence, an accurate early diagnosis is often troublesome. Read More

FoxO1 as a Regulator of Aquaporin 5 Expression in the Salivary Gland.

J Dent Res 2021 Apr 10:220345211003490. Epub 2021 Apr 10.

Department of Pharmacology, School of Dentistry, Kyungpook National University, Daegu, Republic of Korea.

Forkhead box O1 (FoxO1) is a multifunctional initiator, mediator, and repressor of autoimmune diseases in an organ- or disease-specific manner. However, the role of FoxO1 in the salivary gland has not yet been elucidated. In this study, we discovered that FoxO1 and aquaporin 5 (AQP5) are both significantly downregulated in the patients with primary Sjögren syndrome, an autoimmune disease accompanying salivary gland dysfunction.

Animal Models of COVID-19. I. Comparative Virology and Disease Pathogenesis.

ILAR J 2021 Apr 9. Epub 2021 Apr 9.

Department of Comparative Medicine, John Hopkins School of Medicine, Baltimore, Maryland, USA.

The Coronavirus Disease 2019 (COVID-19) pandemic has fueled unprecedented development of animal models to understand disease pathogenesis, test therapeutics, and support vaccine development. Models previously developed to study severe acute respiratory syndrome coronavirus (SARS-CoV) have been rapidly deployed to study SARS-CoV-2. However, it has become clear that despite the common use of ACE2 as a receptor for both viruses, the host range of the 2 viruses does not entirely overlap. Read More

Clinical profile and evolution of patients with juvenile-onset Behçet's syndrome over a 25-year period: insights from the AIDA network.

Intern Emerg Med 2021 Apr 9. Epub 2021 Apr 9.

Research Center of Systemic Auto Inflammatory Diseases, Behçet's Disease and Rheumatology-Ophthalmology Collaborative Uveitis Center, Rheumatology Unit, Policlinico "Le Scotte", Department of Medical Sciences, Surgery and Neurosciences, University of Siena, Viale Bracci 16, 53100, Siena, Italy.

Atypical presentation of immunoglobulin G4-related disease as subglottic stenosis: a case-based review.

Rheumatol Int 2021 Apr 8. Epub 2021 Apr 8.

Division of Rheumatology, Hospital Universitario Marqués de Valdecilla, Avda. Valdecilla s/n, 39008, Santander, Spain.

Background: Immunoglobulin G4-related disease (IgG4-RD) is a recently recognized fibro-inflammatory pathology that has been reported to affect principally the retroperitoneum, hepatobiliary system, salivary glands, orbital structures or lymph nodes. However, IgG4-RD with laryngeal involvement is a very rare entity. Our aims were to describe a case of subglottic stenosis as first and only manifestation of IgG4-RD and review the literature.
