Sjogren's syndrome: Everything you always wanted to know about genetic and epigenetic factors.

Primary Sjögren's syndrome (pSS) is a chronic, systemic autoimmune disease characterized by a wide spectrum of glandular and extra-glandular features. Genetic and epigenetic factors play an important role in the disease susceptibility and phenotype. There are a multitude of genes that have been identified as implicated in the pathogenesis of pSS, both in HLA and extra-HLA regions with a strong contribution given by genes in interferon signalling pathways.

Sudden improvement of alopecia universalis and psoriatic arthritis while receiving upadacitinib: a case-based review.

Alopecia universalis (AU), an advanced form of alopecia areata (AA), is a condition characterized by the complete loss of hair over the entire skin surface. Recent progress has significantly enhanced our understanding of the pathogenesis of AU. In particular, interferon-γ (IFN-γ) and interleukin (IL)-15 seem to play a pivotal role in the pathogenesis of the disease.

Rational approach to the prescription of anti-rheumatic drugs in rheumatoid arthritis: a product leaflet-based strategy in Italy.

The treatment of patients with rheumatoid arthritis (RA) has dramatically changed in the past 30 years. Currently, numerous conventional, biologic, and targeted synthetic DMARDs have been licensed and used following recommendations provided by international and national scientific societies. However, the availability of biosimilars and the increasing necessity of savings impacted on the local/national prescription of these drugs.

Salivary gland biopsy as a prognostic tool in Sjögren's syndrome.

Introduction: Primary Sjögren's syndrome (pSS) is an autoimmune disorder primarily affecting salivary and lacrimal glands, although about 40% of patients experience systemic complications. In this setting, the identification of patient phenotypes characterized by increased risk of extra-glandular involvement still represents an unmet need.

Areas Covered: The aim of this paper is to review the scientific evidence on the utility of salivary gland biopsies in pSS, emphasizing their role in defining prognosis.

Microbiota and arthritis: cause or consequence?

The relationship between intestinal microbiota and arthritis has garnered significant attention, with emerging evidence suggesting a potential association between dysbiosis and various forms of inflammatory arthropathies. While observational studies have provided valuable insights into microbiota alterations in patients with arthritis, establishing causality remains challenging. Observational data, influenced by multiple confounders such as environmental factors, medication effects, and dietary habits, are insufficient to conclusively determine whether microbiota changes are somehow causally linked to arthritis.

Primary Sjögren's syndrome in Italy: Real-world evidence of a rare disease through administrative healthcare data.

Objectives: Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease with significant impact on morbidity, mortality, and quality of life. This study aimed to evaluate epidemiology, healthcare needs and related costs of pSS patients from the Italian National Health Service perspective.

Methods: From the Fondazione Ricerca e Salute's database (∼5 million inhabitants/year), pSS prevalence in 2018 was calculated.

Impact of gender and age at onset on Sjögren's syndrome presentation and outcome: state of the art.

Sjögren's syndrome (SS) is a complex and heterogeneous disease that typically affects middle-aged women. However, while it is rare, the disease may occur in male patients and in females during their childhood/adolescence or in the elderly. Contrasting data have been reported on these three subgroups clinical features and long-term outcomes.

Exploring the Link between Plasma Levels of PCSK9, Immune Dysregulation and Atherosclerosis in Patients with Primary Sjögren's Syndrome.

Proprotein convertase subtilisin/kexin type 9 (PCSK9) regulates lipid metabolism contributing to cardiovascular (CV) risk in the general population. The relationship between PCSK9 and CV risk in systemic autoimmune diseases has been poorly explored. We investigated the association between plasma PCSK9, measures of immune-inflammatory status and markers of atherosclerosis in 52 consecutive patients with primary Sjögren's syndrome (pSS) in comparison to healthy controls (HCs).

Vasculitis associated with adenosine deaminase 2 deficiency: at the crossroads between Behçet's disease and autoinflammation. A viewpoint.

Adenosine deaminase 2 deficiency (DADA2) is a rare monogenic vasculopathy caused by loss-of-function homozygous or compound heterozygous mutations in ADA2, formerly CECR1 (cat eye syndrome chromosome region 1) gene. The DADA2 phenotype is widely heterogeneous, and patients may present with fever, weight loss, livedo reticularis/racemosa, digital ischemia, cutaneous ulceration, peripheral neuropathy, abdominal pain, bowel perforation, and portal or nephrogenic hypertension. More specific manifestations include early-onset ischemic or hemorrhagic stroke, mild immunodeficiency and hypogammaglobinemia, cytopenia, and vision disturbances.

Organ damage in Systemic Lupus Erythematosus patients: A multifactorial phenomenon.

The prevention of chronic damage, especially in early disease phases, remains an unmet need in the management of Systemic Lupus Erythematous (SLE) patients, despite the application of a so-called treat-to-target strategy. The high proportion of SLE patients developing chronic damage suggests a multifactorial aetiology. Thus, besides disease activity, other factors may contribute to the development of damage.

Predictors of complete 24-month remission and flare in patients with polymyalgia rheumatica.

To date, few papers investigated the predictive factors of sustained 24-month remission and of flare in patients with polymyalgia rheumatica (PMR). We retrospectively evaluated clinical charts from PMR patients. Patients were evaluated at baseline, at 1 month, 3 months and subsequently at 6, 12 and 24 months.

Sjögren's syndrome: one year in review 2022.

Primary Sjögren's syndrome (pSS) is a complex disabling systemic autoimmune disorder. The hallmark of pSS is the T-cell-mediated hyperactivation of B-cells, evolving from asymptomatic conditions to systemic complications and lymphoma development. On tissue level, the typical feature is the lymphocytic infiltration of the salivary gland by B-, T- and antigen presenting cells, as mirrored by the diagnostic cornerstone role of minor salivary gland (MSG) biopsy.

Identification of a miRNA-based non-invasive predictive biomarker of response to target therapy in BRAF-mutant melanoma.

Metastatic melanoma is the most aggressive and dangerous form of skin cancer. The introduction of immunotherapy with Immune checkpoint Inhibitors (ICI) and of targeted therapy with BRAF and MEK inhibitors for BRAF mutated melanoma, has greatly improved the clinical outcome of these patients. Nevertheless, response to therapy remains highly variable and the development of drug resistance continues to be a daunting challenge.

Oncosuppressive miRNAs loaded in lipid nanoparticles potentiate targeted therapies in BRAF-mutant melanoma by inhibiting core escape pathways of resistance.

BRAF-mutated melanoma relapsing after targeted therapies is an aggressive disease with unmet clinical need. Hence the need to identify novel combination therapies able to overcome drug resistance. miRNAs have emerged as orchestrators of non-genetic mechanisms adopted by melanoma cells to challenge therapies.

Methotrexate improves endothelial function in early rheumatoid arthritis patients after 3 months of treatment.

Background: Endothelial dysfunction contributes to increased cardiovascular (CV) disease in rheumatoid arthritis (RA). Angiogenic T cells (Tang) are a key regulator of vascular function via their interaction with endothelial progenitor cells (EPCs). Methotrexate (MTX) has been associated to reduced CV disease risk, but its effects on endothelial homeostasis have been poorly explored.

Ultrasound scoring systems affect the distribution of sialadenitis scores in Sjögren's syndrome: an inter-system reproducibility study.

Objectives: Salivary gland ultrasonography (SGUS) is commonly employed in the diagnosis and follow-up of patients with Sjögren's syndrome (SS) and multiple scoring systems have been developed to quantify the grade of sialadenitis of major salivary glands (SG). Their diagnostic performance seems overall comparable, however, the parameters evaluated by the various systems are different. The objective of this study was to compare how four different scoring systems affect the distribution of sialadenitis grades.

C-reactive protein and 10-year cardiovascular risk in rheumatoid arthritis.

Objectives: To evaluate the association between C-reactive protein (CRP) and 10-year risk of cardiovascular (CV) events using the Expanded Cardiovascular Risk Prediction Score for Rheumatoid Arthritis (ERS-RA), based on conventional and RA-specific risk factors but not CRP, in RA patients without previous cardiovascular events.

Methods: ERS-RA was calculated in 1,251 "Cardiovascular Obesity and Rheumatic Disease Study (CORDIS)" database patients [(age 60.4(9.

Cardiovascular Involvement in Sjögren's Syndrome.

Sjögren Syndrome (SS) seems to be associated with a greater "overall risk" of cardiovascular (CV) and cerebrovascular events. Although not conventionally considered a feature of the disease, CV events represent a major burden in SS patients. CV risk is the consequence of a complex combination of multiple factors, including traditional risk factors and disease-related mechanisms.

Unattended compared to traditional blood pressure measurement in patients with rheumatoid arthritis: a randomised cross-over study.

Background: Hypertension is characterised by a high prevalence, low awareness and poor control among rheumatoid arthritis (RA) patients. Correct blood pressure (BP) measurement is highly important in these subjects. The "unattended" BP measurement aims to reduce the "white-coat effect," a phenomenon associated with cardiovascular risk.
