Article Synopsis
  • The study aimed to assess how well the Systemic Lupus Erythematosus Risk Probability Index (SLERPI) performs in diagnosing systemic lupus erythematosus (SLE) among Colombian patients, comparing it with established diagnostic criteria.
  • Researchers collected data from 435 SLE patients and 430 control subjects with other autoimmune diseases, finding that SLE patients had significantly higher SLERPI scores, with key influential factors including immunological disorders and specific skin symptoms.
  • SLERPI showed high sensitivity in identifying SLE, particularly for hematological and renal forms, but had lower specificity compared to traditional criteria, indicating it might be more effective in ruling out SLE rather than confirming it.

Article Synopsis
  • The study aimed to examine the prevalence of polyautoimmunity in patients with type 1 diabetes (T1D) through a systematic review and meta-analysis, following established research guidelines.
  • A total of 158 articles were analyzed, with findings showing an overt polyautoimmunity prevalence of 8.50%, especially higher in North America (14.50%), and a latent polyautoimmunity prevalence of 14.45%, most commonly found in Asia and Oceania.
  • Key characteristics of the latent polyautoimmunity included a variety of autoantibodies and a significant correlation between the duration of T1D and the occurrence of both latent and overt forms of polyautoimmunity.

Article Synopsis
  • Antimicrobial peptides (AMPs) offer a promising solution to combat antibiotic resistance, and a computational approach was used to identify and modify peptide sequences from various organisms to enhance their antimicrobial properties.
  • Out of 150,450 analyzed proteins from multiple sources, 18 modified peptides were tested, resulting in 14 demonstrating antimicrobial effects against several bacterial species and yeast, with some also showing activity against cancer cell lines.
  • Key findings indicate that the most effective AMPs damage bacterial cell membranes, and the study highlights the success of integrating bioinformatics and rational modifications to uncover powerful AMPs hidden in proteins.

Systemic sclerosis (SSc) is a chronic autoimmune disease, marked by an unpredictable course, high morbidity, and increased mortality risk that occurs especially in the diffuse and rapidly progressive forms of the disease, characterized by fibrosis of the skin and internal organs and endothelial dysfunction. Recent studies suggest that the identification of altered metabolic pathways may play a key role in understanding the pathophysiology of the disease. Therefore, metabolomics might be pivotal in a better understanding of these pathogenic mechanisms.

Autoimmunity has emerged as a characteristic of the post-COVID syndrome (PCS), which may be related to sex. In order to further investigate the relationship between SARS-CoV-2 and autoimmunity in PCS, a clinical and serological assessment on 100 patients was done. Serum antibody profiles against self-antigens and infectious agents were evaluated by an antigen array chip for 116 IgG and 104 IgM antibodies.

Background: The immunopathological pathways enabling post-coronavirus disease 2019 (COVID-19) syndrome (PCS) development are not entirely known. We underwent a longitudinal analysis of patients with COVID-19 who developed PCS aiming to evaluate the autoimmune and immunological status associated with this condition.

Methods: Thirty-three patients were included for longitudinal clinical and autoantibody analyses, 12 of whom were assessed for cytokines and lymphocyte populations.

Objective: The clinical coexistence of two or more autoimmune diseases (ADs) fulfilling classification criteria is termed "overt polyautoimmunity" (PolyA), whereas the presence of autoantibodies unrelated to an index AD, without clinical criteria fulfillment, is known as "latent PolyA". We aimed to explore a new taxonomy of ADs based on PolyA.

Methods: In a cross-sectional study of 292 subjects, we evaluated the presence of PolyA in 146, 45, 29, 17, and 17 patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Sjögren's syndrome (SS), autoimmune thyroid disease (AITD) and systemic sclerosis (SSc), respectively, and 38 healthy controls.

Autoimmune responses mediated by autoantibodies have been observed in SARS-CoV-2 infection. Herein, we evaluate the presence of rheumatic, thyroid and phospholipid autoantibodies in sera samples from 120 adult hospitalized patients with COVID-19 in comparison to pre-pandemic samples from 100 healthy individuals. In addition, to estimate the frequency of these autoantibodies in COVID-19, a meta-analysis of selected articles was conducted.

The target organ of neurological autoimmune diseases (NADs) is the central or peripheral nervous system. Multiple sclerosis (MS) is the most common NAD, whereas Guillain-Barré syndrome (GBS), myasthenia gravis (MG), and neuromyelitis optica (NMO) are less common NADs, but the incidence of these diseases has increased exponentially in the last few years. The identification of a specific culprit in NADs is challenging since a myriad of triggering factors interplay with each other to cause an autoimmune response.
