Despite vaccination programs, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection remains a public health problem. Identifying key prognostic determinants of severity of the disease may help better focus health resources. The negative prognostic role for metabolic and hepatic alterations is established; however, the interplay among different metabolic comorbidities and their interconnections with the liver have never been explored.The objective of this study is to evaluate the impact of liver alterations in addition to metabolic comorbidities as a predictor of SARS-CoV-2 severity. 382 SARS-CoV-2 patients were enrolled. Severe SARS-CoV-2 was diagnosed according to international consensus. Transaminases > 2 times the upper limit of normality (2ULN), hepatic steatosis (by ultrasound and/or computed tomography in 133 patients), and FIB-4 defined liver alterations. All data were collected on admission. The results are severe SARS-CoV-2 infection in 156 (41%) patients (mean age 65 ± 17; 60%males). Prevalence of obesity was 25%; diabetes, 17%; hypertension, 44%; dyslipidaemia, 29%; with 13% of the cohort with ≥ 3 metabolic alterations. Seventy patients (18%) had transaminases > 2ULN, 82 (62%) steatosis; 199 (54%) had FIB-4 < 1.45 and 45 (12%) > 3.25. At multivariable analysis, ≥ 3 metabolic comorbidities (OR 4.1, CI 95% 1.8-9.1) and transaminases > 2ULN (OR 2.6, CI 95% 1.3-6.7) were independently associated with severe SARS-CoV-2. FIB-4 < 1.45 was a protective factor (OR 0.42, CI 95% 0.23-0.76). Hepatic steatosis had no impact on disease course. The presence of metabolic alterations is associated with severe SARS-CoV-2 infection, and the higher the number of coexisting comorbidities, the higher the risk of severe disease. Normal FIB-4 values are inversely associated with advanced SARS-CoV-2 regardless of metabolic comorbidities, speculating on use of these values to stratify the risk of severe infection.

Introduction: Rheumatoid arthritis (RA) is a chronic autoimmune disease associated with significant comorbidities, including cardiovascular and respiratory complications, leading to increased hospitalization rates in Intensive Care Units (ICUs) and Cardiac Intensive Care Units (CICUs). This study examines factors related to ICU/CICU admissions among Polish RA patients from 2011 to 2021.
Objectives: The study aims to analyze trends in ICU/CICU admissions, identify key factors influencing outcomes, and assess the impact of comorbidities on RA patient ICU/CICU mortality in critical care settings.

Introduction: Despite progress in systemic lupus erythematosus (SLE) treatment, challenges persist in medication adherence due to side effects and costs. Precision nutrition, particularly adjusting fatty acid intake, offers a cost-effective strategy for enhancing SLE management. Prior research, including our own, indicates that increased consumption of omega-3 polyunsaturated fatty acids (PUFAs) correlates with improved outcomes in SLE patients.

Autoimmune inner ear disease (AIED) is a rare condition characterized by immune-mediated damage to the inner ear, leading to progressive sensorineural hearing loss (SNHL) and vestibular symptoms such as vertigo and tinnitus. This study investigates the pathogenesis and therapeutic strategies for AIED through the analysis of three cases with different underlying autoimmune disorders: rheumatoid arthritis, relapsing polychondritis, and IgG4-related disease. The etiology of AIED involves complex immunopathological mechanisms, including molecular mimicry and the "bystander effect," with specific autoantibodies, such as those against heat shock protein 70 (HSP70), playing a potential role in cochlear damage.

Heart failure with preserved ejection fraction (HFpEF) accounts for approximately 50% of heart failure cases globally, and this incidence is increasing due to extended lifespans and accumulating comorbidities. Emerging evidence suggests that Wnt signaling plays a role in cardiomyocyte hypertrophy and cardiac fibrosis, which are key features of HFpEF. Furthermore, Porcupine (PORCN) inhibitors, which negatively regulate Wnt signaling, have shown promising results in improving cardiac function and reducing cardiac hypertrophy and/or fibrosis.
