Abstract
Omeprazole, a drug of choice for the management of gastric hyperacidity, influences serotonergic neurotransmission in brain regions and its long-term use is known to cause stress-related behavioral deficits including anxiety. Aim of the current study was to explore the effects of omeprazole treatment on immobilization-induced anxiety in rats, specifically on the role of serotonin (5-HT). In view of the role of serotonin-1A (5-HT1A) autoreceptor in the availability of 5-HT in brain regions, mRNA expression of this autoreceptor was performed in raphe nuclei. Similarly, because of the role of hippocampal 5-HT neurotransmission in anxiety-like disorders, expression of the 5-HT1A heteroreceptors was determined in this region. We found that the treatment with omeprazole reduces anxiety-like behavior in rats, increases the expression of 5-HT1A autoreceptor in the raphe and decreases the hippocampal expression of 5-HT1A heteroreceptor. This suggests a role of 5-HT1A receptor types in omeprazole-induced behavioral changes. It also indicates a potential role of omeprazole in the management of serotonergic disorders.

Abstract
AIMS Gastrointestinal disease is a leading cause of morbidity in bottlenose dolphins (Tursiops truncatus) under managed care. Fecal microbiota transplantation (FMT) holds promise as a therapeutic tool to restore gut microbiota without antibiotic use. This prospective clinical study aimed to develop a screening protocol for FMT donors to ensure safety, determine an effective FMT administration protocol for managed dolphins, and evaluate the efficacy of FMTs in four recipient dolphins. METHODS AND RESULTS Comprehensive health monitoring was performed on donor and recipient dolphins. Fecal samples were collected before, during, and after FMT therapy. Screening of donor and recipient fecal samples was accomplished by in-house and reference lab diagnostic tests. Shotgun metagenomics was used for sequencing. Following FMT treatment, all four recipient communities experienced engraftment of novel microbial species from donor communities. Engraftment coincided with resolution of clinical signs and a sustained increase in alpha diversity. CONCLUSION The donor screening protocol proved to be safe in this study and no adverse effects were observed in four recipient dolphins. Treatment coincided with improvement in clinical signs.

Alterations of gut microbiome following gastrointestinal surgical procedures and their potential complications. Front Cell Infect Microbiol 2023; 13:1191126. [PMID: 37333847 PMCID: PMC10272562 DOI: 10.3389/fcimb.2023.1191126] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Accepted: 05/23/2023] [Indexed: 06/20/2023] Open
Abstract
Intestinal microorganisms play a crucial role in shaping the host immunity and maintaining homeostasis. Nevertheless, alterations in gut bacterial composition may occur and these alterations have been linked with the pathogenesis of several diseases. In surgical practice, studies revealed that the microbiome of patients undergoing surgery changes and several post-operative complications seem to be associated with the gut microbiota composition. In this review, we aim to provide an overview of gut microbiota (GM) in surgical disease. We refer to several studies which describe alterations of GM in patients undergoing different types of surgery, we focus on the impacts of peri-operative interventions on GM and the role of GM in development of post-operative complications, such as anastomotic leak. The review aims to enhance comprehension regarding the correlation between GM and surgical procedures based in the current knowledge. However, preoperative and postoperative synthesis of GM needs to be further examined in future studies, so that GM-targeted measures could be assessed and the different surgery complications could be reduced.

Metagenomic profiling reveals dominance of gram-positive bacteria in the gut microbiome shifts associated with immunoglobulin A vasculitis (Henoch-Schönlein Purpura). Clin Transl Immunology 2021; 10:e1342.

Abstract
Objectives Immunoglobulin A vasculitis (IgAV), previously known as Henoch-Schönlein purpura, is the most common vasculitis that has a classical skin manifestation of palpable purpuric rash. Factors pertinent to IgAV remain inadequately understood. Here, we aimed to examine the gut microbiome shifts associated with IgAV and its recovery. Methods Stool samples were collected from 10 children with IgAV (6-14 years old) before and after a multi-drug therapy, along with 9 age-matched healthy children. The samples were subjected to metagenomic analyses to investigate the taxonomic and functional shifts of the gut microbiome. Results The analyses revealed that compared with healthy controls, treatment-naïve patients exhibited substantial taxonomic and functional alterations of gut microbiota, including 104 IgAV-depleted species and 7 IgAV-elevated species (FDR < 0.05). After treatment, the IgAV patients displayed a partial restoration of the microbiota shifts, as the relative abundances of some biomarkers (e.g. 9 genera and 22 species) became comparable (FDR > 0.1) between the patients and healthy controls. The treatment-responsive features included Weissella, Faecalibacterium prausnitzii and Bifidobacterium pseudocatenulatum and three components of a putative glutamine transport system. Importantly, gram-positive bacteria accounted for over 85% of the numbers and total relative abundance of the species that were associated with IgAV and responsive to the treatment. In addition, of the 122 IgAV-depleted bacterial genes, 82 were mainly contributed by gram-positive bacteria and 12 by gram-negative bacteria. Conclusions Gram-positive bacteria are the main drivers underlying the gut microbiome shifts of IgAV, which may assist rational management of the disease.

Drug Metab Pharmacokinet 2020; 35:534-538. [PMID: 33028492 DOI: 10.1016/j.dmpk.2020.08.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 08/03/2020] [Accepted: 08/16/2020] [Indexed: 10/23/2022]
Abstract
Erlotinib shows pH-dependent solubility and its absorption is decreased in patients receiving gastric acid suppression therapy. Here, we examined whether administration of erlotinib in acidic solutions would improve its solubility and absorption characteristics. In vitro, the solubility of erlotinib in HCl solution increased with decreasing pH, and was far higher than that in tap water. The solubility in apple juice (pH 3.7) was higher than that in HCl solution of the same pH. In vivo, the absorption of erlotinib administered in tap water was decreased in omeprazole-treated (OP) rats, used as a model of gastric acid suppression, compared to control rats. In the OP rats, the plasma concentrations in the groups given erlotinib in apple juice and in HCl (pH 3.7) were significantly higher than in the tap water group in the initial phase of absorption. AUC in OP rats given erlotinib in apple juice was 1.69-fold larger than that of control rats given erlotinib in tap water, and 2.49-fold larger than that of OP rats given erlotinib in tap water. Thus, administration of erlotinib in an acidic beverage to patients receiving gastric acid suppression therapy might be effective to increase solubility and absorption.

Abstract
Research in the past decade has shown that variations in the gut microbiome may influence behavior, and vice versa. As such, interest in the role of the gut microbiome in psychiatric conditions has drawn immense interest. This is evidenced by the recent surge in published studies examining microbial dysbiosis in clinical psychiatric populations, particularly autism spectrum disorder and depression. However, critical examination of these studies reveals methodological flaws in design and execution, suggesting that they may not be held to the same standards as other bodies of clinical research. Given the complex nature of the gut microbiome, this narrative review attempts to clarify concepts critical to effectively examine its potential role in psychopathology to appropriately inform mental health researchers. More specifically, the numerous variables known to affect the gut microbiome are discussed, including inflammation, diet, weight, and medications. A comprehensive review of the extant microbiome literature in clinical psychiatric populations is also provided, in addition to clinical implications and suggestions for future directions of research. Although there is a clear need for additional studies to elucidate the gut microbiome's role in psychiatric disorders, there is an even greater need for well-designed, appropriately controlled studies to truly impact the field.
