During the perioperative period of cardiac disease, as many risk factors exist, such as primary cardiac diseases, the use of vasopressors, ischemia-reperfusion injury during cardiopulmonary bypass (CPB), and surgical stress, the gut suffered from ischemia, anoxia and oxidative stress, which would lead to the enterocyte injury. The aim of this study was to explore whether serum intestinal fatty acid-binding protein (IFABP), which is excreted specifically from damaged intestinal enterocytes, as a predictor of prognosis in postoperative cardiac surgery patients...

Graft-versus-host disease (GVHD) in the gastrointestinal (GI) tract remains the major cause of morbidity and non-relapse mortality after bone marrow transplantation (BMT). The Paneth cell protein, regenerating islet-derived 3-alpha (REG3α), is a biomarker specific for GI GVHD. REG3α serum levels rose in the systematic circulation as GVHD progressively destroyed Paneth cells and reduced GI epithelial barrier function. Paradoxically, GVHD suppressed intestinal REG3γ (the mouse homologue of human REG3α), and the absence of REG3γ in BMT recipients intensified GVHD but did not change the composition of the microbiome...

Immunoglobulin A vasculitis (IgAV) is an immune complex, small vessel vasculitis with dominant IgA deposits in vessel walls, predominantly affecting the pediatric population. However, adults frequently have more severe gastrointestinal tract (GIT) and renal involvements as compared to children. Our aim was to study serological and cellular biomarkers to support clinicians in their diagnosis and the course of IgAV in adult patients. This cross-sectional study included 62 adult IgAV patients and 53 healthy blood donors (HBDs)...

Monkeys demonstrate gastrointestinal barrier dysfunction (leaky gut) as evidenced by higher biomarkers of microbial translocation (MT) and inflammation with ageing despite equivalent health status, and lifelong diet and environmental conditions. We evaluated colonic structural, microbiomic and functional changes in old female vervet monkeys (Chlorocebus aethiops sabeus) and how age-related leaky gut alters responses to Western diet. We additionally assessed serum bovine immunoglobulin therapy to lower MT burden...

Altered extracellular matrix (ECM) remodeling is an important part of the pathology of gastrointestinal (GI) disorders. In the intestine, type XVI collagen (col-16) plays a role in pathogenesis by affecting ECM architecture and induce cell invasion. Measuring col-16 in serum may therefore have biomarker potential in GI disorders such as colorectal cancer (CRC) and ulcerative colitis (UC). The aim of this study was to determine whether col-16 can serve as a biomarker for altered ECM remodeling in patients with CRC and UC...

The tumor necrosis factor⁻related weak inducer of apoptosis (TWEAK) belongs to the tumor necrosis factor ligand superfamily, which was shown to play an important role in inflammatory and malignant gastrointestinal diseases, including colitis or colorectal cancer. However, in contrast to other members of the TNF ligand superfamily, its role as a biomarker in pancreatic cancer is currently unknown. We analyzed serum levels of A proliferation-inducing ligand (APRIL) and TWEAK in 134 patients with pancreatic cancer...

OBJECTIVES: The presence of serological markers associated with inflammatory bowel disease (IBD) has been studied in spondyloarthritis with conflicting results. The anti-glycan antibodies: anti-laminaribioside, anti-chitobioside, and anti-mannobioside carbohydrate antibodies (ALCA, ACCA, and AMCA) are serological markers previously associated with IBD. We aim to investigate the prevalence of these antibodies in spondyloarthritis in comparison with rheumatoid arthritis (RA) patients. METHODS: Serum samples were obtained from consecutive patients with spondyloarthritis and were compared to RA and healthy controls...

Ongoing inflammation in the gastrointestinal tract and loss of the mucosal barrier are key components of Crohn's disease. Current treatment paradigms, including treat-to-target, are based on improvement of both clinical and endoscopic symptoms. Endoscopy is an essential tool for the evaluation of mucosal healing, but patients may be reluctant to undergo repeated procedures. Surrogate markers of inflammation, such as C-reactive protein and fecal calprotectin, are being used, yet they have several limitations in the assessment of mucosal healing...

Gastric and esophageal cancers are as main cancers of the gastrointestinal (GI) tract, which are associated with poor diagnosis and survival. Several efforts were made in the past few decades to finding effective therapeutic approaches, but these approaches had several problems. Finding new biomarkers is a critical step in finding new approaches for the treatment of these cancers. Finding new biomarkers that cover various aspects of the diseases could provide a choice of suitable therapies and better monitoring of patients with these cancers...

Background: Major abdominal surgery (MAS) is high-risk intervention usually accompanied by tissue injury leading to a release of signaling danger molecules called alarmins. This study evaluates the surgical injury caused by two fundamental types of gastrointestinal surgical procedures (open surgery and laparoscopy) in relation to the inflammation elicited by alarmins. Patients and methods: Patients undergoing MAS were divided into a mixed laparoscopy group (LPS) and an open surgery group (LPT)...

BACKGROUND: Crohn's disease (CD) is a chronic, relapsing and remitting disease of the gastrointestinal tract that can cause significant morbidity and disability. Current treatment guidelines recommend early intervention with immunosuppressant or biological therapy in high-risk patients with a severe disease phenotype at presentation. The feasibility of therapeutic de-escalation once remission is achieved is a commonly encountered question in clinical practice, driven by patient and clinician concerns regarding safety, adverse events, cost and national regulations...

Telomere length dysfunction is involved in the generation of genomic rearrangements that drive progression to malignancy. A set of serological markers for telomere dysfunction, namely chitinase and N-acetylglucosaminidase (NAG), DNA damage, and tissue alteration of p53 have been identified. The probability that genomic damage, accumulation of reactive oxygen species, and shorter telomeres may be related to the onset and advancement of gastrointestinal (GI) tumors. A total of 40 patients with GI tumors and 20 healthy controls with matched age and sex were included...

The dysregulation of inflammatory response to surgical injury affects outcomes. Alarmins, the earliest bioactive substances from damaged cells, play a crucial role in initiating the inflammation. We analyzed serum levels of alarmins (S100A8, S100A12, high mobility group box, and heat shock protein 70) after major abdominal surgery (MAS) in surgical (S) (n = 82) and nonsurgical (NS) groups (n = 35). The main objective was determining a role of selected alarmins in host response to MAS. The secondary objectives were (i) evaluation of the relationship among alarmins and selected biomarkers (C-reactive protein, interleukin-6), (ii) influence of the place of gastrointestinal resection, and (iii) role of alarmins in MAS for cancer...

Background: Dysbiosis, especially a reduced Clostridium subcluster XIVa (XIVa), has been reported in several gastrointestinal diseases. Since XIVa is thought to be the main bacterial cluster that metabolizes bile acids (BAs) in the human intestine, we hypothesized that the BA profile in feces, and possibly in serum, could be a convenient biomarker for intestinal XIVa activity. Methods: First, blood and feces were collected from 26 healthy controls and 20 patients with gastrointestinal diseases, and the relationships among fecal microbiomes and fecal and serum BA compositions were studied...

Autofluorescence emission of liver tissue depends on the presence of endogenous biomolecules able to fluoresce under suitable light excitation. Overall autofluorescence emission contains much information of diagnostic value because it is the sum of individual autofluorescence contributions from fluorophores involved in metabolism, for example, NAD(P)H, flavins, lipofuscins, retinoids, porphyrins, bilirubin and lipids, or in structural architecture, for example, fibrous proteins, in close relationship with normal, altered or diseased conditions of the liver...
