Pruritogenic molecules in the skin of patients with dermatomyositis.

Introduction: Pruritus is a common excruciating symptom in systemic autoimmune diseases such as dermatomyositis (DM) but the pathogenesis is not fully understood. We intended to investigate the targeted expression analysis of candidate molecules involved in the development of pruritus in lesional vs. non-lesional skin samples of patients affected with active DM.

Incidence, features, and outcome of disease relapse after COVID-19 vaccination in patients with idiopathic inflammatory myopathies.

Introduction/aims: Vaccination against coronavirus disease 2019 (COVID-19) is relatively safe in patients with idiopathic inflammatory myopathies (IIM); however, myositis flares following vaccination have been poorly studied. We aimed to evaluate the frequency, features, and outcomes of disease relapses in patients with IIM following COVID-19 vaccination.

Methods: A cohort of 176 IIM patients were interviewed after the third wave of the COVID-19 pandemic and followed prospectively.

The effect of COVID-19 pandemic on idiopathic inflammatory myositis patients: a single centre experience.

Objectives: Pandemic caused by coronavirus disease (COVID-19) determines the life of clinicians and patients since 2 years. We have a lot of information about disease course, treatment and protection against virus, but less on the prognosis of infection in patients with idiopathic inflammatory myopathies (IIM). Also few data are available on triggered humoral response and side effects after vaccination.

Clinical, Serological, and Genetic Characteristics of a Hungarian Myositis-Scleroderma Overlap Cohort.

Overlap myositis is a distinct subgroup of idiopathic inflammatory myositis (IIM) with various clinical phenotypes. The aim of this study was to determine the clinical, serological, and genetic features of systemic sclerosis (SSc)-IIM overlap patients. It was a retrospective study using clinical database of 39 patients, fulfilling both the criteria of SSc and IIM.

Bone Health in Idiopathic Inflammatory Myopathies: Diagnosis and Management.

Purpose Of Review: This article provides an update on the most recent advances in epidemiology, pathogenesis, diagnostic procedures, and therapeutic approaches for myositis-associated bone diseases, such as osteoporosis and bone fractures.

Recent Findings: In the recent years, several studies showed that osteoporosis and consequent fractures are a common and frequently underestimated complication in patients with idiopathic inflammatory myopathies (IIM). In younger patients, asymptomatic fractures might present in the early phase of the disease which could increase the risk of development of further fractures.

The risk of fracture and prevalence of osteoporosis is elevated in patients with idiopathic inflammatory myopathies: cross-sectional study from a single Hungarian center.

Background: The prevalence of osteoporosis and risk of fractures is elevated in rheumatoid arthritis (RA), but we have limited information about the bone mineral density (BMD) and fracture risk in patients with inflammatory myopathies. We intended to ascertain and compare fracture risk, bone mineral density and the prevalence of vertebral fractures in patients with inflammatory myositis and rheumatoid arthritis and to assess the effect of prevalent fractures on the quality of life and functional capacity.

Methods: Fifty-two patients with myositis and 43 patients with rheumatoid arthritis were included in the study.

Effect of Genetic and Laboratory Findings on Clinical Course of Antisynthetase Syndrome in a Hungarian Cohort.

The aim of this study was to determine the clinical, serological, and genetic features of anti-Jo-1 positive antisynthetase patients followed by a Hungarian single centre to identify prognostic markers, which can predict disease phenotypes and disease progression. It was a retrospective study using clinical database of 49 anti-Jo-1 positive patients. 100% of patients exhibited myositis, 73% interstitial lung disease, 88% arthritis, 65% Raynaud's phenomenon, 43% fever, 33% mechanic's hand, and 12% dysphagia.
