Background: Investigation of the inflammatory response of immune cells is a current focus of research on autoimmune disorders. The aim of this study was to evaluate the inflammatory status of monocytes/macrophages in systemic sclerosis (SSc).

Methods: The study included 35 SSc and 25 healthy participants.

[Clinical and laboratory features of rheumatoid arthritis in men depending on testosterone levels].

Background:  It has been suggested that the presence of chronic immunoinflammatory rheumatic disease (CIRD) may be a factor that increases the likelihood of developing hypogonadism syndrome, and conversely, the presence of uncompensated testosterone deficiency may predispose to a greater risk of developing or more severe course of ICRD.

Aim:  To study the incidence of hypogonadism in men with rheumatoid arthritis (RA) and evaluate its impact on the course of RA and concomitant diseases.

Materials And Methods:  A one-time continuous study included 170 men with RA who were undergoing inpatient treatment at the Federal State Budgetary Institution NIIR named after.

Combination of Sjögren's syndrome and anti-Ku syndrome complicated by the development of mucosa-associated lymphoid tissue lymphoma: case review and systematic review of the literature.

The frequency of antibodies to Ku varies in various autoimmune diseases. In 2019, Spielmann et al. identified two types of anti-Ku syndrome based on a hierarchical clustering analysis.

Long-term efficacy and safety of subcutaneous tocilizumab in clinical trials of polyarticular or systemic juvenile idiopathic arthritis.

Objective: To investigate the safety and efficacy of subcutaneous tocilizumab (SC-TCZ) treatment in a long-term extension (LTE) of clinical trials in polyarticular or systemic juvenile idiopathic arthritis (pJIA or sJIA).

Methods: Patients with pJIA or sJIA from two open-label, 52-week phase 1b core trials of SC-TCZ who had adequate response per investigator assessment entered the LTE and continued SC-TCZ treatment according to body weight-based dosing regimens until commercial availability or up to 5 years. Pharmacokinetics, pharmacodynamics, and efficacy were assessed for up to 3 years, and safety for up to 5 years in the LTE.

Gut Microbiota and Biomarkers of Intestinal Barrier Damage in Cirrhosis.

Gut dysbiosis and subclinical intestinal damage are common in cirrhosis. The aim of this study was to examine the association of intestinal damage biomarkers (diamine oxidase [DAO], claudin 3, and intestinal fatty acid binding protein [I-FABP; FABP2]) with the state of the gut microbiota in cirrhosis. The blood levels of DAO were inversely correlated with blood levels of claudin 3, lipopolysaccharide (LPS), presepsin, TNF-α, and the severity of cirrhosis according to Child-Pugh scores.

Genetically engineered CD80-pMHC-harboring extracellular vesicles for antigen-specific CD4 T-cell engagement.

The identification of low-frequency antigen-specific CD4 T cells is crucial for effective immunomonitoring across various diseases. However, this task still encounters experimental challenges necessitating the implementation of enrichment procedures. While existing antigen-specific expansion technologies predominantly concentrate on the enrichment of CD8 T cells, advancements in methods targeting CD4 T cells have been limited.

Systemic Sclerosis and Atherosclerosis: Potential Cellular Biomarkers and Mechanisms.

Systemic sclerosis (SSc) is a rare systemic autoimmune disease of unknown etiology, which is characterized by endothelial dysfunction, pathologic vasculopathy, and increased tissue fibrosis. Traditionally, SSc has been regarded as a prototypical fibrotic disease in the family of systemic autoimmune diseases. Traditionally, emphasis has been placed on the three components of the pathogenesis of SSc: vascular, immune, and mesenchymal.

Investigation of the variability of the pterygomandibular space from the point of view of the target point of the inferior alveolar nerve block.

Introduction: A thorough knowledge of the anatomy and variability of the pterygomandibular space (PMS) is essential to the success of local anesthesia. This study is aimed at determining the volume of the PMS depending on the shape of the skull, face and mandible using the computed tomography (CT).

Materials And Methods: anonymized computed tomograms of 48 adult patients were analyzed, the indicators of the cranial index (CI), facial index (FI) according to Yzard, the high lengthy index of the mandible (HLI), the latitudinal-altitude index of the mandible (LAI), the longitudinal latitude index of the mandible (LLI) were calculated.

[Clinical features, diagnostics and treatment of FGF23 secreting tumors: series of 40 clinical cases].

Introduction: Tumor-induced osteomalacia is an acquired rare disease manifested by hypophosphatemic osteomalacia due to excessive secretion of fibroblast growth factor 23 (FGF23). FGF 23 is a non-classical hormone secreted by bone tissue (osteocytes) and regulates phosphorus metabolism.The aim of this work is to present clinical experience in the diagnosis, treatment and rehabilitation of patients with tumor-induced osteomalacia.

A New Way to Model Periodontitis in Laboratory Animals.

Unlabelled: The prevalence of periodontal diseases is increasing, tends to increase with age and is considered as one of the main causes of tooth loss. To assess the effectiveness of new methods of treatment of periodontal diseases, studies on laboratory animals can be promising.

The Aim Of The Study: to develop a new method of accelerated modeling of experimental periodontitis on laboratory animals.

[Impact of surgical treatment of morbid obesity on joint diseases].

The prevalence of obesity in the modern world is increasing. Obesity is an independent risk factor for some rheumatic diseases and also worsens their course. The presence of chronic joint disease can make it difficult for obesity to reduce activity, creating a vicious circle where joint pain makes exercise difficult and being overweight exacerbates joint pain.

The Role of Neutrophil Extracellular Traps (NETs) in the Pathogenesis of Systemic Lupus Erythematosus and Antiphospholipid Syndrome.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease of unknown aetiology [...

Successful experience of tofacitinib treatment in patients with Fibrodysplasia Ossificans Progressiva.

Fibrodysplasia ossificans progressive (FOP) is an ultra-rare genetic disorder that is caused by a mutation in the ACVR1 gene and provokes severe heterotopic ossification. Since flares of the disease are associated with inflammation, it is assumed that JAK inhibitors can control active FOP due to blocking multiple signaling pathways.

What is the best instrument to measure disease activity in SLE? - SLE-DAS vs Easy BILAG.

Systemic lupus erythematosus (SLE) is a heterogeneous condition making assessment of disease activity challenging. However, thorough assessment is essential to evaluate patients longitudinally, to guide therapeutic decisions, and for clinical trials. Currently, the most popular disease activity index in clinical practice and trials is SLEDAI-2K.

Musculoskeletal manifestations of systemic lupus erythematosus.

MSK is the most common and impactful symptom of lupus at a population level. It has a variety of different presentations, but joint swelling is often not present despite imaging-proven synovitis. Imaging with US and MRI has been shown to improve detection of inflammation and identify treatment-responsive patients.

Effect of Heliogeophysical and Atmospheric Factors on the Degree of Synchronization of Ultradian Rhythms of Body Temperature in Mice.

In a long-term (8 months) study, we examined the degree of synchronization of ultradian body temperature oscillations of two isolated groups of mice kept under constant dim illumination. In most cases, the periods of increased activity accompanied by rapid elevation of body temperature coincided in these groups of mice, but in some days, no significant synchronization between the examined parameters was observed. Analysis of the effects of environmental factors on the degree of synchronization of ultradian rhythms in mice revealed association of this parameter with the dynamics of atmospheric pressure (AtmP) and to a lesser extent with the vertical component of interplanetary magnetic field Bz.

Predictors of Pulmonary Hypertension and Right Ventricular Dysfunction in Patients with Hypersensitivity Pneumonitis.

Background: Hypersensitivity pneumonitis (HP) is an interstitial lung disease (ILD) that occurs in susceptible individuals in response to various inhaled antigens. The fibrotic phenotype of HP is characterized by disease progression and can lead to pulmonary hypertension (PH). The aim of this study was to estimate the prevalence of PH and to identify predictors of PH in patients with chronic HP.
