Obeagu EI, Obeagu GU. Exploring the intersection: Peptic ulcers and hemolysis-Unraveling the complex relationship. Medicine (Baltimore) 2024; 103:e37565. [PMID: 38489683 PMCID: PMC10939687 DOI: 10.1097/md.0000000000037565] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Revised: 01/22/2024] [Accepted: 02/20/2024] [Indexed: 03/17/2024] Open
Abstract
This paper investigates the intriguing relationship between peptic ulcers and hemolysis, 2 seemingly distinct medical conditions, aiming to unravel their potential interconnections and clinical implications. While traditionally studied in isolation, recent evidence has surfaced suggesting possible links and shared mechanisms between these conditions. This paper explores the underlying pathophysiological associations, shared risk factors, diagnostic challenges, management strategies, and implications for clinical practice and health policy. The interplay between peptic ulcers and hemolysis stems from shared inflammatory pathways, notably attributed to Helicobacter pylori infection in peptic ulcers, which might trigger systemic inflammatory responses contributing to hemolysis. Common risk factors including genetic predispositions, autoimmune disorders, and medication use (such as nonsteroidal anti-inflammatory drugs) are implicated in the development of both peptic ulcers and hemolytic conditions, suggesting a potential convergence of these disorders in affected individuals. Diagnostic considerations pose challenges, as overlapping symptoms and laboratory findings may complicate accurate differentiation between peptic ulcers and hemolysis. Recognizing the potential interplay between peptic ulcers and hemolysis holds significant implications for clinical practice and health policy. Streamlining diagnostic algorithms, fostering interdisciplinary collaborations, and developing tailored guidelines are pivotal in optimizing patient care. Continued research efforts, collaborative clinical approaches, and informed health policies are essential in advancing our understanding and enhancing patient care for individuals navigating the intersection of peptic ulcers and hemolysis.

Abstract
The protein composition of human milk plays a crucial role in infant formula milk powder formulation. Notably, significant differences exist between bovine casein and human milk casein. Previous studies have shown that casein hydrolysates could enhance immune function; however, gastrointestinal dyspepsia in infants affects the type and function of peptides. Therefore, the present study used peptidomics to sequence and analyze hydrolyzed peptides from different casein fractions. Additionally, animal experiments were conducted to assess the functionality of these casein fractions and elucidate their differences. The results revealed variations in peptide composition among the different casein fractions of formula milk powder. Interestingly, milk powder formulated with both β- and κ-casein (BK) exhibited significant enrichment of peptides related to the immune system. Moreover, the BK group significantly alleviated immune organ damage in cyclophosphamide-treated mice and regulated serum levels of pro-inflammatory and anti-inflammatory factors. Furthermore, feeding different casein fractions influenced the intestinal microflora of cyclophosphamide-treated mice, with the BK group mitigating the changes caused by cyclophosphamide. In conclusion, the findings suggest that BK formula in milk powder has the potential to positively enhance immunity. This study provides a robust theoretical basis for human-emulsified formula milk powder development.

Abstract
Interferon-induced tetrapeptide repeat (IFIT) family proteins are an important component of the antiviral immune response. There are four known members of the human IFIT family, namely IFIT1, IFIT2, IFIT3 and IFIT5. More and more evidence shows that IFIT family members are involved in a variety of pathophysiological processes in vivo, regulate the homeostasis and differentiation of a variety of cells including immune cells, and are closely related to a variety of autoimmune diseases, which is expected to become a new therapeutic target. This review reviews the biological roles of different IFIT proteins in various autoimmune diseases, and highlights the potential use of these molecules as biomarkers and prognostic factors in autoimmune diseases, with a view to providing ideas for exploring the diagnosis and treatment of autoimmune diseases.

Abstract
Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease of undefined etiology, with persistent synovial inflammation and destruction of articular cartilage and bone. Current clinical drugs for RA mainly include non-steroidal anti-inflammatory drugs (NSAIDs), glucocorticoids, disease modifying anti-rheumatic drugs (DMARDs) and so on, which can relieve patients' joint symptoms. If we want to have a complete cure for RA, there are still some limitations of these drugs. Therefore, we need to explore new mechanisms of RA to prevent and treat RA radically. Pyroptosis is a newly discovered programmed cell death (PCD) in recent years, which is characterized by the appearance of holes in cell membranes, cell swelling and rupture, and the release of intracellular pro-inflammatory factors into the extracellular space, resulting in a strong inflammatory response. The nature of pyroptosis is pro-inflammatory, and whether it is participating in the development of RA has attracted a wide interest among scholars. This review describes the discovery and mechanism of pyroptosis, the main therapeutic strategies for RA, and the role of pyroptosis in the mechanism of RA development. From the perspective of pyroptosis, the study of new mechanisms of RA may provide a potential target for the treatment of RA and the development of new drugs in the clinics.

Abstract
Rheumatoid arthritis (RA) is an incurable systemic autoimmune disease. Disease progression leads to joint deformity and associated loss of function, which significantly impacts the quality of life for sufferers and adds to losses in the labor force. In the past few decades, RA has attracted increased attention from researchers, the abnormal signaling pathways in RA are a very important research field in the diagnosis and treatment of RA, which provides important evidence for understanding this complex disease and developing novel RA-linked intervention targets. The current review intends to provide a comprehensive overview of RA, including a general introduction to the disease, historical events, epidemiology, risk factors, and pathological process, highlight the primary research progress of the disease and various signaling pathways and molecular mechanisms, including genetic factors, epigenetic factors, summarize the most recent developments in identifying novel signaling pathways in RA and new inhibitors for treating RA. therapeutic interventions including approved drugs, clinical drugs, pre-clinical drugs, and cutting-edge therapeutic technologies. These developments will hopefully drive progress in new strategically targeted therapies and hope to provide novel ideas for RA treatment options in the future.

Abstract
Genomic incorporation of viruses as human endogenous retroviruses (HERVs) are components of our genome that possibly originated by incorporating ancestral of exogenous viruses. Their roles in the evolution of the human genome, gene expression, and the pathogenesis of autoimmune diseases (ADs) and neoplastic phenomena are the subject of intense research. This review analyzes the evolutionary and virological aspects of HERVs and other viruses that incorporate their genome into the human genome and have known role in the genesis of ADs. These insights are helpful to understand further the possible role in autoimmunity genesis of HERVs, other ancestral viruses no HERVs and modern viruses with the ability to incorporate into the human genome or interact with HERVs.
