Abstract
Henoch-Schönlein purpura (HSP) is a common form of IgA1-mediated blood vessel inflammation affecting mainly children. Intercellular adhesion molecule-1 (ICAM-1) gene polymorphisms have been shown to be associated with HSP in different populations; in this study, we investigated its potential association and influence on the development of severe complications in Iranian HSP patients. Twenty-three patients diagnosed with IgAV/HSP according to the criteria of the American College of Rheumatology (ACR) with 53 age- and sex-matched control subjects were referred to us. Cases and controls were genotyped using Sanger sequencing. Based on our research data, we found an association between codon 469 K/E of the ICAM1 gene and risk of HSP. Our results revealed that KK genotype and allele K are more common in control than in the HSP group, therefore the subjects with KK genotype are protected against HSP. Our data also suggested that the genotype EE is associated with higher risk of HSP progression compared to KK genotype.

Int J Mol Sci 2024; 25:4383. [PMID: 38673968 PMCID: PMC11050592 DOI: 10.3390/ijms25084383] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 04/11/2024] [Accepted: 04/13/2024] [Indexed: 04/28/2024] Open
Abstract
The pathogenesis of IgAV, the most common systemic vasculitis in childhood, appears to be complex and requires further elucidation. We aimed to investigate the potential role of galactose-deficient immunoglobulin A1 (Gd-IgA1), high-mobility group box 1 (HMGB1), receptor for advanced glycation end products (RAGE) and protocadherin 1 (PCDH1) in the pathogenesis of IgAV. Our prospective study enrolled 86 patients with IgAV and 70 controls. HMGB1, RAGE, Gd-IgA1 and PCDH1 in serum and urine were determined by the enzyme-linked immunosorbent assay (ELISA) method at the onset of the disease and after a six-month interval in patients and once in the control group. Serum concentrations of HMGB1, RAGE and PCDH1 and urinary concentrations of HMGB1, RAGE, Gd-IgA1 and PCDH1 were significantly higher in patients with IgAV than in the control group (p < 0.001). Concentrations of HMGB1 (5573 pg/mL vs. 3477 pg/mL vs. 1088 pg/mL, p < 0.001) and RAGE (309 pg/mL vs. 302.4 pg/mL vs. 201.3 pg/mL, p = 0.012) in the serum of patients remained significantly elevated when the disease onset was compared with the six-month follow-up interval, and thus could be a potential marker of disease activity. Urinary concentration of HMGB1 measured in the follow-up period was higher in patients with nephritis compared to IgAV without nephritis (270.9 (146.7-542.7) ng/mmol vs. 133.2 (85.9-318.6) ng/mmol, p = 0.049) and significantly positively correlated with the urine albumine to creatinine ratio (τ = 0.184, p < 0.05), the number of erythrocytes in urine samples (τ = 0.193, p < 0.05) and with the outcome of nephritis (τ = 0.287, p < 0.05); therefore, HMGB1 could be a potential tool for monitoring patients with IgAV who develop nephritis. Taken together, our results imply a possible interplay of Gd-IgA1, HMGB1, RAGE and PCDH1 in the development of IgAV. The identification of sensitive biomarkers in IgAV may provide disease prevention and future therapeutics.

Abstract
BACKGROUND Malnutrition and cachexia are common syndromes in patients with gastric cancer (GC) and are associated with poor quality of life and poor disease prognosis. However, there is still a lack of molecular factors that can predict malnutrition or cachexia in cancer. Studies have shown that among the potential contributors to the development of cancer cachexia, the level of the inflammatory response to P-selectin is regulated by single nucleotide polymorphisms (SNPs) located in the promoter region of the SELP gene. The aim of this study was to evaluate the association between the single nucleotide polymorphism (SNP)-2028 A/G of the SELP gene and malnutrition in patients receiving chemotherapy for gastric cancer (GC). METHODS The study group consisted of 220 GC patients treated with chemotherapy at Jinhua Municipal Central Hospital. DNA was extracted from peripheral leukocytes of whole blood samples using an animal DNA extraction kit. DNA was amplified using a 1.1 × T3 Super PCR mix, and loci corresponding to the peaks were genotyped using SNP1 software. RESULTS Patients carrying the A allele had a reduced risk of developing malnutrition compared to patients with the GG genotype (P < 0.001; OR = 3.411; 95% CI = 1.785-6.516). In addition, multivariate analysis indicated that the AA genotype significantly (more than 16-fold) reduced the risk of developing malnutrition (P < 0.001; OR = 0.062; 95% CI = 0.015-0.255). CONCLUSION SELP -2028A/G SNP may be a useful marker for assessing the risk of malnutrition in GC patients.

Abstract
We aimed to investigate the changes in p-selectin (p-sel), thrombus precursor protein, and D-dimer (D-D) in patients with cirrhosis after portal hypertensive splenectomy and explore its values on the prediction of postoperative portal vein thrombosis (PVT) formation. A total of 144 patients with cirrhosis with portal hypertension who underwent portal hypertensive splenectomy from January 2009 to December 2016 were enrolled in this study and divided into the thrombus and nonthrombus groups. The levels of p-sel, thrombus precursor protein (TpP), and D-D were measured by flow cytometry, enzyme-linked immunosorbent assay, and immunoturbidimetry, respectively. Sensitivity, specificity, and other values for p-sel, TpP, and D-D were calculated. The linear discriminant, logistic regression, and decision tree methods were used to analyze the p-sel value on the prediction of PVT formation. Seventy-nine patients were confirmed having postoperative PVT, with the incidence rate of 54.86%. No significant differences were observed in the p-sel, TpP, and D-D between the thrombus and nonthrombus groups before surgery, but these 3 indexes were obviously elevated in the thrombus group after operation (P < .01). P-selectin level on first day showed the highest positive predictive value (91.0%) and diagnostic coincidence rate (83.3%), while negative expected value (76.6%) was lower than those of TpP and D-D. Multiple analyses showed the prediction accuracy of PVT was 61.1% (P = .023), 97.2% (P < .001), and 97.2% (P < .001), respectively. P-selectin has a significant value in predicting PVT. P-selectin level on first and third day is valuable and feasible for the early prediction of PVT.

Abstract
Helicobacter pylori (H. pylori) is the most common infection in humans, with a marked disparity between developed and developing countries. Although H. pylori infections are asymptomatic in most infected individuals, they are intimately related to malignant gastric conditions such as gastric cancer and gastric mucosa-associated lymphoid tissue (MALT) lymphoma and to benign diseases such as gastritis and duodenal and gastric peptic ulcers. Since it was learned that bacteria could colonize the gastric mucosa, there have been reports in the medical literature of over 50 extragastric manifestations involving a variety medical areas of specialization. These areas include cardiology, dermatology, endocrinology, gynecology and obstetrics, hematology, pneumology, odontology, ophthalmology, otorhinolaryngology and pediatrics, and they encompass conditions with a range of clear evidence between the H. pylori infection and development of the disease. This literature review covers extragastric manifestations of H. pylori infection in the hematology field. It focuses on conditions that are included in international consensus and management guides for H. pylori infection, specifically iron deficiency, vitamin B12 (cobalamin) deficiency, immune thrombocytopenia, and MALT lymphoma. In addition, there is discussion of other conditions that are not included in international consensus and management guides on H. pylori, including auto-immune neutropenia, antiphospholipid syndrome, plasma cell dyscrasias, and other hematologic diseases.

Abstract
Henoch-Schönlein purpura (HSP) is a leukocytoclastic vasculitis classically characterized by palpable purpura, arthritis, abdominal pain and renal disease. In this article, we summarize our current understanding of the pathogenesis of HSP and the implications for improving its diagnosis. Although the pathogenesis of HSP is not fully understood yet, exciting new information has emerged in recent years, leading to a better understanding of its pathogenesis. Here, we discuss genetic predisposition, immunoglobulins with a particular emphasis on IgA1, activated complements, cytokines and chemokines, abnormal coagulation and autoantibodies in the underlying pathogenic mechanisms. Finally, diagnostic criteria for HSP developed by institutions such as the American College of Rheumatology and the European League against Rheumatism/Paediatric Rheumatology European Society were proposed to improve early detection and diagnosis.

Abstract
Helper T (Th) cells comprising Th1, Th2, Th17, and Treg are involved in the pathogenesis of various vascular inflammations, and information about Th cells in Henoch-Schonlein purpura (HSP) is still controversial. The aim of our study was to investigate the changes in CD4(+) T cell subsets and their roles in the pathogenesis of HSP. Thirty children with diagnosis of HSP and thirty age-matched healthy controls were enrolled in this study. Real-time PCR was used to evaluate the mRNA expression levels of transcriptional factors and cytokines of CD4(+) T cells. Proportions of Th1, Th2, Th17, and Treg cells in peripheral blood were detected by flow cytometry. Plasma cytokine concentrations were measured by ELISA. The proportions of Th2 and Th17 cells increased significantly in children with acute HSP (P < 0.05), while there were no significant differences between HSP and healthy controls regarding the proportions of Treg cells and Th1 cells (P > 0.05). mRNA levels of transcriptional factors and cytokines of Th2 and Th17 cells were significantly up-regulated (P < 0.05), while the differences were not significant as to those of Th1 and Treg cells (P > 0.05). Plasma concentrations of IL-17A, IL-4, and IL-6 in patients with HSP were found to be much higher than those of the control group (P < 0.05), and no differences between IFN-γ, IL-12, and TGF-β were detected between the two groups (P > 0.05). Presence of higher proportions of Th2 and Th17 cells in patients with HSP could be closely correlated with aberrant creation of antibody and development of vessel vasculitis. The changes in cytokine milieu in peripheral blood may play an important role in the derangement of CD4(+) T cell subset.

Abstract
Henoch-Schonlein purpura (HSP) is the most common systemic vasculitis in childhood. The etiology and pathogenesis of HSP are still not very clear. The diagnostic criteria for HSP include palpable purpura with at least one other manifestation-abdominal pain, IgA deposition, arthritis or arthralgia, or renal involvement. Bacterial and viral infections are the most common triggers for HSP involving the gastrointestinal (GI) tract. The clinical manifestations of HSP include purpura, colicky abdominal pain and bloody stools. Some HSP patients have severe complications. Ultrasound is usually the first choice because it permits prompt detection of the involved gut and complications. Endoscopy permits direct observation of the mucous and biopsy of affected areas to detect abnormal IgA deposition or leukocytoclastic vasculitis (LCV). There are two types of diseases that should be differentiated from HSP involving the GI: diseases demonstrating purpura and those demonstrating thickened bowel wall. The majority of children with HSP improve spontaneously, and few patients need medications. Surgical intervention is usually not recommended.

Abstract
PURPOSE OF REVIEW To examine recent advances in the pathophysiology and therapy of pediatric vasculitis. RECENT FINDINGS The past 2 years have been marked by significant progress in extending novel techniques to the investigation of the two most common pediatric vasculitis syndromes, Henoch-Schonlein purpura and Kawasaki disease. Study of other vasculitides, such as Wegener granulomatosis, Churg-Strauss syndrome, and microscopic polyangiitis, is impeded by the small number of pediatric patients. Nonetheless, national and international registries are beginning to provide the foundation for generation of testable hypotheses regarding pathogenesis and optimal treatment. Thus, recent data from the study of children suggest that disorders in the control of inflammation, such as those that underlie familial Mediterranean fever and other autoinflammatory diseases, may predispose to vasculitis. Improved knowledge of mechanisms of disease, in turn, should pave the way for more targeted, effective, and tolerable therapies for children with systemic vasculitis. SUMMARY International collaboration to study rare disorders such as pediatric vasculitis are demonstrating disorders of inflammatory regulation that predispose to these diseases and may point toward new treatment approaches.
