Introduction: Impaired high-density lipoprotein (HDL) levels and antioxidant functionality of HDL, mainly attributed to a decreased paraoxonase-1 (PON1) functionality, have been described in autoimmune conditions. In this setting, a role for humoral response in cardiovascular disease is emerging. This study evaluates the role of immunoglobulin G (IgG) antibodies against HDL and disease-related autoantibodies on HDL dysfunction in immune-driven diseases. Methods: Serum IgG anti-HDL antibodies, PON1 activity, and total antioxidant capacity (TAC) were quantified in 381 patients with different immune-driven diseases [18 mixed connective tissue disease (MCTD), 35 primary Sjögren syndrome (pSS), 38 systemic sclerosis (SSc), 33 ANCA-associated vasculitis (AAV), 60 diabetes mellitus 1, 29 autoimmune B12 deficiency/pernicious anemia, 29 primary biliary cirrhosis, 46 IBD/Crohn, 54 IBD/UC, and 39 celiac disease (CD)] and 138 healthy controls...

Previous studies have demonstrated that early surgery in Crohn disease (CD) can result in a better clinical course than late surgery. The aim of this study was to compare the clinical course of CD following bowel resection performed at the time of diagnosis (early surgery) and during the course of the disease (late surgery).We reviewed medical records from a hospital-based cohort database that includes Korean CD patients diagnosed before 2009. Patients who underwent bowel resection were included. Age, sex, disease phenotype, time of surgery, medication history including use of corticosteroids, immunomodulators, and biologics, and further surgical history were assessed...

The human intestinal microbiota has a close relationship with health control and causes of diseases, and a vast number of scientific papers on this topic have been published recently. Some progress has been made in identifying the causes or species of related microbiota, and successful results of data mining are reviewed here. Humans who are targets of a disease have their own individual characteristics, including various types of noise because of their individual life style and history. The quantitatively dominant bacterial species are not always deeply connected with a target disease...

The human body is colonized by millions of microorganisms named microbiota that interact with our tissues in a cooperative and non-pathogenic manner. These microorganisms are present in the skin, gut, nasal, oral cavities, and genital tract. In fact, it has been described that the microbiota contributes to balancing the immune system to maintain host homeostasis. The gut is a vital organ where microbiota can influence and determine the function of cells of the immune system and contributes to preserve the wellbeing of the individual...

Patients with Crohn's disease (CD) are shown to have abnormal changes in brain structures. This study aimed to further investigate whether these patients have abnormal brain activities and network connectivity. Sixty patients with CD and 40 healthy controls (HCs) underwent resting-state functional magnetic resonance imaging (fMRI) scans. Amplitude of low-frequency fluctuation (ALFF) and seed-based functional connectivity (FC) were used to assess differences in spontaneous regional brain activity and functional connectivity...

BACKGROUND AND OBJECTIVES: Crohn's disease is a multifactorial inflammatory disease affecting mainly the gastrointestinal tract. The genetic factors that are involved in the disease include mainly three mutations of the gene NOD2/CARD15 (R702W, G908R, 3020insC). The aim of this study was to determine the relationship between the presence of these variants and disease phenotype. MATERIAL AND METHODS: 70 patients with Crohn's disease were examined for the presence of the above-mentioned mutations...

Irritable Bowel Syndrome (IBS) shares overlapping symptoms and some features of pathogenesis with Inflammatory Bowel Diseases (IBD: Crohn's disease [CD], and Ulcerative Colitis [UC]). Geographic markers such as latitude/sunshine and more recently lactase population distributions are found to be correlated with IBD. As a result of clinical and pathogenic similarities between the 2 conditions, some authorities questioned whether a connection exists between them. We compare IBS directly with IBD, and indirectly with geographic markers associated with IBD, in order to evaluate possible evolutionary links between IBS and IBD...

Crohn's disease (CD) has been reported to relate with the functional and structural alterations in several local brain regions. However, it remains unknown whether the possible abnormalities of information transmission and integration between brain regions are associated with CD. The purpose of this study was to investigate the topological alterations of brain functional networks and the potential relationships between the neuroimaging findings and CD clinical characteristics. 43 remissive CD patients and 37 matched healthy controls (HCs) were recruited to obtain their resting-state functional magnetic resonance imaging (fMRI) data...

Intestinal fibrosis, a common complication of inflammatory bowel diseases, becomes clinically apparent in ~ 40% of patients with Crohn's disease and ~ 5% of those with ulcerative colitis. Fibrosis, a consequence of local chronic inflammation, is characterized by excessive deposition of extracellular matrix (ECM) proteins by activated myofibroblasts, which are modulated by pro-fibrotic and anti-fibrotic factors. Fibrosis depends on the balance between production and degradation of ECM proteins. Although the transforming growth factor (TGF)-β1/Smad pathway is the major driving force of fibrosis, several pro-fibrogenic and anti-fibrogenic endogenous factors appear to interact directly with this pathway such as reactive oxygen species (ROS) and nuclear factor-erythroid 2-related factor 2 (Nrf2), which are connected with TGF-β1 during fibrosis development in several organs, including the intestine...

COMMENT
Naohiro Inohara
In a recent study published in Science, Atarashi et al. (2017) showed that Klebsiella strains isolated from the saliva of Crohn's disease patients can induce Th1 cell responses to promote colitis. Their findings highlight the importance of the oral cavity as a potential reservoir for bacteria that can promote intestinal disease.

Acupuncture and moxibustion have been shown to be effective in treating Crohn's disease (CD), but their therapeutic mechanisms remain unclear. Here we compared brain responses to either electro-acupuncture or moxibustion treatment in CD patients experiencing remission. A total of 65 patients were randomly divided into an electro-acupuncture group ( n = 32) or a moxibustion group ( n = 33), and treated for 12 weeks. Eighteen patients in the electro-acupuncture group and 20 patients in the moxibustion group underwent resting-state functional magnetic resonance imaging at baseline and after treatment...

Paneth cells, specialized secretory epithelial cells of the small intestine, play a pivotal role in host defense and regulation of microbiota by producing antimicrobial peptides especially-but not only-the human α-defensin 5 (HD5) and HD6. In small intestinal Crohn's disease (CD) which is an entity of inflammatory bowel diseases, the expression of HD5 and HD6 is specifically compromised leading to a disturbed barrier and change in the microbial community. Different genetically driven but also non-genetic defects associated with small intestinal CD affect different lines of antimicrobial Paneth cell functions...

Johne's disease is a chronic granulomatous enteritis caused by Mycobacterium avium subsp. paratubercolosis (MAP) which affects ruminants worldwide and has a significant economic impact. MAP has also been associated with human Crohn's disease, although this connection is not well established. MAP is highly adapted for survival within host macrophages and prevents macrophage activation, blocks phagosome acidification and maturation, and attenuates presentation of antigens to the immune system. The consequence is a very long silent infection before clinical signs are observed...

Psychological factors and comorbidities play an important role in inflammatory bowel diseases. Such comorbidity could be associated with a specific neural phenotype. Brain regions associated with emotion regulation and self-referential processing, including areas assigned to the "default mode network" (DMN), could be promising candidates in this regard. We investigated the functional integrity of multiple intrinsic neural networks in remitted patients with Crohn's disease (CD) and sought to establish relationships between neural network connectivity and psychiatric symptoms...

It is becoming increasingly clear that the connections between our immune system and the microbiota colonizing us have a tremendous impact on human health. A number of innate molecular defence mechanisms cooperate to selectively target unwanted microorganisms at the mucosal surfaces. Amongst others these include the complement system, IgA and the SALSA molecule. The salivary scavenger and agglutinin (SALSA), also known as deleted in malignant brain tumors 1 (DMBT1), salivary agglutinin (SAG) or gp340 is a multifunctional molecule with important functions in innate immunity, inflammation and epithelial homeostasis...

In East Asian traditional medicine, Pulsatillae Radix (PR) is widely used to treat amoebic dysentery and renowned for its anti-inflammatory effects. This study aimed to confirm evidence regarding the potential therapeutic effect of PR on Crohn's disease using a system network level based in silico approach. Study results showed that the compounds in PR are highly connected to Crohn's disease related pathways, biological processes, and organs, and these findings were confirmed by compound-target network, target-pathway network, and gene ontology analysis...
