Diseases of the digestive organs and covid-19

TL;DR: Therapy for patients with COVID-19 should include therapeutic approaches aimed at correcting disorders of the intestinal microbiota, intestinal barrier permeability, and relief of gastroenterological manifestations.
Abstract: With a new coronavirus infection (COVID-19), gastroenterological symptoms are often detected, which is due to both the damage to the digestive organs by the SARS-CoV-2 coronavirus and the exacerbation of chronic diseases, as well as aggressive multicomponent therapy. The severity of gastroenterological manifestations, primarily impaired liver function, is associated with a more severe and complicated course of COVID-19 infection. Numerous mechanisms of damage to the digestive organs in COVID-19 have been identified: direct damage by the virus due to resuscitation and multicomponent therapy, impaired central and peripheral nervous regulation, immunothrombotic syndrome, virus persistence in the gastrointestinal tract, induction of autoimmune reactions by the virus, humoral disorders (changes in serotonin levels, bradykinin, activation of mast cells). Violation of the microbial-tissue complex of the intestine and the permeability of the intestinal barrier, induced by the SARS-CoV-2 virus, ensures the formation and progression of chronic systemic inflammation, cytokine aggression, insulin resistance, endothelial dysfunction, which affect the severity of the infection. Therapy for patients with COVID-19 should include therapeutic approaches aimed at correcting disorders of the intestinal microbiota, intestinal barrier permeability, and relief of gastroenterological manifestations

TL;DR: In this paper , a review of the etiology, pathogenesis and clinical presentation of Irritable Bowel Syndrome (IBS) is presented, focusing on the role of psycho-emotional disorders, changes localized at the level of the intestinal wall; and a new coronavirus infection COVID-19 in the development of IBS.
Abstract: Among functional gastrointestinal disorders, Irritable bowel syndrome (IBS) rightfully continues to maintain its leading position. IBS is a kind of standard for understanding the pathogenetic essence of functional diseases of the digestive system, since it is the most common, studied and studied pathology. So, for the query "Irritable Bowel Syndrome" in the electronic database PubMed as of July 30, 2022, 16 599 sources were found, and for the query "Irritable Bowel Syndrome" in the scientific electronic library eLIBRARY.RU 6316. The first part of the review deals with topical aspects of the etiology, pathogenesis and clinical presentation of IBS. The urgency of the problem of IBS is associated with a significant decrease in the quality of life of patients. The review focuses on the role of psycho-emotional disorders, changes localized at the level of the intestinal wall; and a new coronavirus infection COVID-19 in the development of IBS. Abdominal pain as the leading manifestation of IBS is associated primarily with spasm. In this context, antispasmodic drugs can be considered not only as symptomatic agents, but also as pathogenetic therapy for IBS. In the second part of the review, the possibilities of one of the myotropic antispasmodics, mebeverine hydrochloride, in the treatment of IBS are considered in detail.

TL;DR: In this article , the authors analyzed changes in mortality rates and the structure of causes of death in the Irkutsk Region before the pandemic of the novel coronavirus disease and after its onset.
Abstract: Introduction: The COVID-19 pandemic has significantly affected mortality from many causes. In recent years, mortality rates in the Irkutsk Region have exceeded the Russian national averages. Objective: To analyze changes in mortality rates and the structure of causes of death in the Irkutsk Region before the pandemic of the novel coronavirus disease and after its onset. Materials and methods: We compared the Irkutsk regional mortality rates and causes of death with those registered in the population of the Siberian Federal District and the Russian Federation in 2010–2019, prior to the pandemic, and in the year 2020. Results: In 2010–2019, the all-cause mortality rate in the Irkutsk Region decreased by 8.6 %, while those from diseases of the respiratory system and injury and poisonings dropped by 45.1 % and 33.6 %, respectively. In 2020, COVID-19 ranked fourth in the causes of death structure while death rates from all causes, diseases of the respiratory, digestive, endocrine, and nervous systems demonstrated a statistical increase. In total, the regional mortality rate from infectious diseases and COVID-19 in 2020 was 162.9 per 100,000 population ranking third in the structure of causes of death and inferior only to diseases of the circulatory system and neoplasms. Conclusion: We have traced the impact of the COVID-19 pandemic on all-cause mortality in the general population and on deaths from specific causes, directly or indirectly related to the novel coronavirus disease. In 2020, the regional trend towards an increase in life expectancy was interrupted.

TL;DR: In the patients with a history of COVID-19, along with respiratory syndromes, gastrointestinal symptoms are seen, with their types being variable at various period of the coronavirus infection.
Abstract: Aim: To analyze prevalence and type of symptomatic gastrointestinal involvement during symptomatic COVID-19 (up to 412 weeks after the disease) and post-COVID-19 syndrome (more than 12 weeks from the disease onset). Materials and methods: We retrospectively analyzed the data from 785 in-patients with the diagnosis of COVID-19, who were treated in the infectious disease hospital from May to December 2020. At the first phase of the study we analyzed how frequently they were referred for out-patient care by a gastroenterology specialist after they were discharged from the hospital (all 785 patient medical files). At the 2nd study phase we performed phone calls to 247 patients, that were discharged from the infectious disease hospital, during which a specially designed questionnaire was filled with items on their comorbidities, general and specific complaints, as well as the standardized Gastrointestinal Symptom Rating Scale (GSRS). Results: Within 2 years after their discharge from the infectious disease hospital, 88 patients asked for specialized gastroenterological care on an out-patient basis. The most common diagnoses were pancreatic diseases (33%), gastric disorders (31%), intestinal disorders (25%), liver and biliary disorders (11%). At referral, the most common complaints were dyspeptic: nausea, bitter taste in the mouth, heartburn, bloating (25%), abdominal pains of various location (17%) and stool abnormalities, such as diarrhea and constipation (11%). Among patients who participated in the phone survey (N = 247), symptomatic COVID-19 was observed in 90 (11.46%) cases, with predominant complaints being loss of taste, loss of smell, and fever. Post-COVID-19 syndrome was identified in 157 (20%) cases, with their main complaints being weakness, shortness of breath and joint pain. Stool abnormalities and abdominal pain occurred during symptomatic COVID-19 and in the post-COVID-19 period with the same frequency (9% and 10%, respectively). According to the GSRS results, the post-COVID-19 dyspeptic syndrome was characterized by prevailing complaints of heartburn (24%), upper abdominal pain and discomfort (20%), and bloating (15%). Conclusion: In the patients with a history of COVID-19, along with respiratory syndromes, gastrointestinal symptoms are seen, with their types being variable at various period of the coronavirus infection. In the early COVID-19, these are stool abnormalities and abdominal pain, and during the post-COVID-19 syndrome, nausea, bitter taste in the mouth, heartburn and bloating are more common.

TL;DR: A new analysis on gene expression data from cells in bronchoalveolar lavage fluid from COVID-19 patients that were used to sequence the virus identifies a critical imbalance in RAS represented by decreased expression of ACE in combination with increases in ACE2, renin, angiotensin, key RAS receptors, kinogen and many kallikrein enzymes that activate it, and both bradykinin receptors.
Abstract: Neither the disease mechanism nor treatments for COVID-19 are currently known. Here, we present a novel molecular mechanism for COVID-19 that provides therapeutic intervention points that can be addressed with existing FDA-approved pharmaceuticals. The entry point for the virus is ACE2, which is a component of the counteracting hypotensive axis of RAS. Bradykinin is a potent part of the vasopressor system that induces hypotension and vasodilation and is degraded by ACE and enhanced by the angiotensin1-9 produced by ACE2. Here, we perform a new analysis on gene expression data from cells in bronchoalveolar lavage fluid (BALF) from COVID-19 patients that were used to sequence the virus. Comparison with BALF from controls identifies a critical imbalance in RAS represented by decreased expression of ACE in combination with increases in ACE2, renin, angiotensin, key RAS receptors, kinogen and many kallikrein enzymes that activate it, and both bradykinin receptors. This very atypical pattern of the RAS is predicted to elevate bradykinin levels in multiple tissues and systems that will likely cause increases in vascular dilation, vascular permeability and hypotension. These bradykinin-driven outcomes explain many of the symptoms being observed in COVID-19.

TL;DR: In this paper, a systematic review and meta-analysis aimed to identify studies assessing long-term effects of COVID-19 and estimates the prevalence of each symptom, sign, or laboratory parameter of patients at a post-COVID19 stage.
Abstract: COVID-19, caused by SARS-CoV-2, can involve sequelae and other medical complications that last weeks to months after initial recovery, which has come to be called Long-COVID or COVID long-haulers. This systematic review and meta-analysis aims to identify studies assessing long-term effects of COVID-19 and estimates the prevalence of each symptom, sign, or laboratory parameter of patients at a post-COVID-19 stage. LitCOVID (PubMed and Medline) and Embase were searched by two independent researchers. All articles with original data for detecting long-term COVID-19 published before 1st of January 2021 and with a minimum of 100 patients were included. For effects reported in two or more studies, meta-analyses using a random-effects model were performed using the MetaXL software to estimate the pooled prevalence with 95% CI. Heterogeneity was assessed using I2 statistics. The Preferred Reporting Items for Systematic Reviewers and Meta-analysis (PRISMA) reporting guideline was followed. A total of 18,251 publications were identified, of which 15 met the inclusion criteria. The prevalence of 55 long-term effects was estimated, 21 meta-analyses were performed, and 47,910 patients were included. The follow-up time ranged from 15 to 110 days post-viral infection. The age of the study participants ranged between 17 and 87 years. It was estimated that 80% (95% CI 65-92) of the patients that were infected with SARS-CoV-2 developed one or more long-term symptoms. The five most common symptoms were fatigue (58%), headache (44%), attention disorder (27%), hair loss (25%), and dyspnea (24%). All meta-analyses showed medium (n=2) to high heterogeneity (n=13). In order to have a better understanding, future studies need to stratify by sex, age, previous comorbidities, severity of COVID-19 (ranging from asymptomatic to severe), and duration of each symptom. From the clinical perspective, multi-disciplinary teams are crucial to developing preventive measures, rehabilitation techniques, and clinical management strategies with whole-patient perspectives designed to address long COVID-19 care.
