Immunofluorescence (IF) was applied to quantify the expression and localization of barrier function proteins: Claudin-1 (CLDN-1), Claudin-4 (CLDN-4), Zonulin-1 (ZO-1), E-Cadherin and Mucin-1 (MUC1). Barrier functionality was measured by TEER.</p><p><strong>Results: </strong>In the acidic microenvironment, TEER measurement has shown some limitations and results were not applicable, whereas the evaluation of protein localization and quantification provided clear and robust evidence of the damage which occurred to the epithelium barrier structure. CLDN-4 expression significantly decreased after exposure to acid. ZO-1 protein appeared upregulated immediately after exposure to HCl and was mainly localized in the cytoplasm and not on the cell membrane. This different localization was also observed for CLND-1.

This review summarizes the literature on adherence and patient preference to 5-ASA in patients with UC. We begin by highlighting key studies that measure real-world adherence rates, as well as some of the pitfalls associated with certain techniques. We examine the data on the consequences of non-adherence, which range from decreased quality of life and higher risk of colorectal cancer at the individual level to increased costs to the overall healthcare system. We then turn to the reasons and risk factors for non-adherence and summarize the current understanding of the barriers towards adherence. Afterwards, we describe the research on patient preferences between 5-ASA formulations and dosing regimen. Finally, we summarize the evidence regarding interventions to improve 5-ASA adherence.

We want to express our gratitude to the authors for publishing such a thorough review study and would like to make some suggestions. The paper discussed a variety of multisystem illnesses and their pathophysiological links to disorders of gut brain interface (DGBI) and gastrointestinal motor dysfunction, presenting gastroenterologists with a foundation for differential diagnosis. Although the article mentioned most of the systemic disorders, we noticed the lack of the overlap of GI symptoms and autism spectrum disorder (ASD) core symptoms. Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder which manifests as variable phenotypes with different subendo-phenotypes that may represent GI abnormalities. A meta-analysis carried out in 2014 by McElhanon et al, showed that children with ASD, unlike the comparison groups, expressed significantly more general GI symptoms: diarrhea, abdominal pain, and constipation. Recent studies have shown the shared pathogenic factors and pathophysiological mechanisms revealing the possible link between GI and ASD disturbances, including inflammation of intestine with or without autoimmunity, visceral hypersensitivity with functional abdominal pain and autonomic dysfunction with GI reflux and dysmotility. Absent or slow acquirement of bowel training secondary to trouble with sensory processing and motor problems may lead to altered GI motility and defecation physiology. Research carried out by Afzal et al concluded moderate-to-severe constipation in 36% of children with ASD compared to 9% in a control population. The diagnosis of GI disorders in patients with ASD can be very challenging due to the behavioral expressions, thus, doctors recommend using less invasive methods of investigation before hospitalization. In his research, Wasilewska et al concluded that GI disorders in children with ASD may vary greatly in their nature and localization. Due to the phenotypical representation as comorbidity of ASD and GI disorders, we suggest treating this situation as an “overlap syndrome”. Children with ASD who have GI disease and are experiencing unexplained anxiety, self-injury, sleep deprivation, aggression, and agitation will benefit from this concept.
