ABSTRACT
Objective: To analyze and compare the effects of different clinical characteristics on the negative conversion time of nucleic acid detection after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant infection, and to provide a scientific basis for the isolation and treatment of coronavirus disease 2019 (COVID-19). Methods: The epidemiological and clinical data of 228 mild SARS-CoV-2 Omicron variant infected patients diagnosed in Shanghai were retrospectively collected from April 27, 2022 to June 8, 2022 in Wujiaochang designated Hospital, Yangpu District, Shanghai. The negative conversion time of nucleic acid detection was used as the outcome variable, and the patients were divided into A (18 days) and B (>18 days). Univariate and multivariate logistic regression analysis were used to analyze the influencing factors of the negative conversion time of nucleic acid detection. Results: The mean nucleic acid conversion time of 228 patients was (18.7+or-12.1) d, with the median time of 18 (2-46) d. Among them, 120 patients in group A had an average nucleic acid conversion time of (13.2+or-2.0) d, and 108 cases in group B had an average nucleic acid conversion time of (20.8+or-1.3) d. Univariate analysis showed that there were no statistically significant differences in the effects of hypertension, coronary heart disease, diabetes, hypokalemia, malignant tumors, neuropsychiatric diseases, chronic digestive diseases on the negative nucleic acid conversion time (P > 0.05);however, there were significant differences in the effects of combined cerebrovascular disease, leukopenia, chronic respiratory system diseases and vaccination on the negative nucleic acid conversion time (P < 0.05). Further multivariate logistic regression analysis revealed that the combination of chronic respiratory diseases and non-vaccination were significant risk factors for prolongation of negative nucleic acid conversion time (P < 0.05). Conclusions: The results of this study show that gender, age and whether hypertension, coronary heart disease, diabetes mellitus, hypokalemia, malignant tumor, neuropsychiatric disease and chronic digestive disease have no significant effect on the nucleic acid conversion time, whereas chronic respiratory disease and no vaccination are significantly correlated with the prolongation of nucleic acid conversion time in SARS-CoV-2 Omicron-infected patients.
ABSTRACT
Background and purpose: Multisystem Inflammatory Syndrome in Children (MIS-C) occurs after having COVID-19. The severity and outcomes of COVID-19 with gastrointestinal symptoms are higher. The aim of this study was to investigate gastrointestinal manifestations in MIS-C patients in selected referral hospitals in Iran to obtain comprehensive information about the treatment and prevention of MIS-C. Materials and methods: In this cross-sectional study, all MIS-C patients <21 years in Dec 2019 to Oct 2021 were included. The patients were identified by the Centers for Disease Control and Prevention (CDC) checklist and data were analyzed applying t-test and Chi-square in STATA11. Results: There were 225 patients with a median age of 55 months (26-96 months), including 59.56% boys and all had fever on admission. At least one gastrointestinal symptom was seen in 200 patients and the most common symptoms were vomiting (60.9%) and abdominal pain (45.77%). Almost 60% of the patients had positive RT-PCR results. Among the patients with and without gastrointestinal symptoms 85.5% and 48% were admitted to intensive care unit (ICU), respectively. There were significant differences between the two groups in respiratory symptoms, ALT, AST, NT-pro BNP, ESR, and PLT (P < 0.05). All patients without gastrointestinal symptoms were discharged but nine patients in the group with gastrointestinal symptoms deceased. Conclusion: According to the current study, gastrointestinal symptoms are common in MIS-C patients and are associated with higher rates of death and intensive care unit admission. Therefore, in providing services to COVID-19 patients, all typical and atypical signs and symptoms should be considered to prevent unnecessary interventions.
ABSTRACT
COVID-19 is mainly a respiratory illness caused by the SARS-CoV-2 but can also lead to GI symptoms. The primary host receptor which mediates the mechanism as SARS-CoV-2 enters the cell is the ACE2 receptor. Therefore, GI symptoms can be common in COVID-19, and in some cases, they are the first manifestation even before fever and respiratory symptoms. In addition, the liver function tests alteration often is related to a worse prognosis. The exact incidence of GI symptoms is a matter of debate. Moreover, wide variation concerning GI symptoms frequency exists, but the predominant ones seem to be diarrhea, anorexia, nausea, vomiting, and abdominal pain or discomfort.This review summarizes the most relevant findings of COVID-19 on the digestive system, including the liver, biliary tract, pancreas, the most common GI symptoms, and the atypical clinical GI manifestations.Copyright © 2022 Sociedad Medica del Hospital General de Mexico.

ABSTRACT
Objectives: Due to large sample sizes, electronic medical records (EMR) databases have the potential to provide pivotal insights into patients diagnosed with rare, orphan, or emerging diseases. This study aimed to explore the patient profile of African and American trypanosomiasis, both vector-borne parasitic diseases, pre-and post the COVID-19 pandemic using the TriNetX Network. Method(s): From Jan 1, 2018 - Nov 30, 2019 (pre-COVID) and Jan 1, 2020 - Nov 30, 2021 (post-COVID) patients were queried from the TriNetX Global health research network, inclusive of 88 million patients from the United States (US), Europe, the Middle East, Africa, Latin America, and Asia Pacific. Eligible patients with an ICD-10 diagnosis code of African trypanosomiasis or American trypanosomiasis were identified (2280 patients on 22-Dec-2022) and analyzed separately, pre- and post-COVID. Result(s): We identified 340 patients pre- and 960 patients post-COVID with African trypanosomiasis and 960 patients pre- and 190 patients post-COVID with American trypanosomiasis. Most patients resided in the US. Pre-COVID African trypanosomiasis patients had a mean age of 38 and were 59% female while post-COVID patients had a mean age of 34 and were 57% female. Pre-COVID American trypanosomiasis patients had a mean age of 49 and were 57% female while post-COVID patients had a mean age of 49 and were 53% female. Top co-diagnoses included diseases of the respiratory (85%, 84%) and nervous systems (82%, 79%) for patients with African trypanosomiasis and diseases of the digestive (69%, 54%) and circulatory systems (68%, 61%) for patients with American trypanosomiasis in both the pre- and post-COVID cohorts, respectively. Conclusion(s): Using real-world EMR data we were able to obtain patient profiles for a rare disease (African trypanosomiasis) and a common, emerging disease (American trypanosomiasis). This informationsupportsutilizing EMR data for describing patient populations in rare, orphan, or emerging diseases, which may aid drug development for these indications.Copyright © 2023
ABSTRACT
Objectives: To assess the characteristics of FDA renal toxicity boxed warnings (formerly called Black Box Warning) included in the labels of drugs approved by the FDA and marked in the US. Method(s): We extracted the labels of human prescription drugs with renal toxicity boxed warnings from the "FDA Label: Full-Text Search of Drug Product Labeling" database, FDA regulatory information from drugs@FDA as of September 1, 2022. We extracted the therapeutic classification from the WHO ATC system. We conducted a descriptive analysis of the data. Result(s): The FDA listed 86 drugs including 72 active ingredients and 14 combinations with a boxed warning mentioning renal toxicity. Three drugs had emergency use authorizations for COVID-19, and all combinations included metformin. There were 8 (8.7%) drugs with renal toxicity boxed warnings approved before 1970, 6 (6.5%) in the 1970s, 14 (15.2%) in the 1980s, 34 (37.0%) in the 1990s, 17 (18.5%) in the 2000s, 9 (9.8%) in the 2010s, and 4 (4.3%) in 2020-Sep 2022. The therapeutic classes with the largest number of renal toxicity boxed warning included anti-infectives for systemic use 24 (26.1%), antineoplastic and immunomodulating agents 22 (23.9%), and alimentary tract and metabolism 17 (18.5%). The most common boxed warnings included renal impairment (n=21, 22.8%), nephrotoxicity (10, 10.9%), and nephrogenic systemic fibrosis (7, 7.6%). Additionally, 9 (9.8%) boxed warnings referred to the potential problems for patients with kidney transplants. Conclusion(s): Most drugs with a boxed warning were approved in the 1990s and 2000s. The therapeutic classes with the highest number of renal toxicity warnings were anti-infective for systemic use, antineoplastic and immunomodulating agents, and alimentary tract and metabolism. The most common warnings were renal impairment, nephrotoxicity, nephrogenic systemic fibrosis, and issues for patients with kidney transplants. Future research could expand the analysis to renal toxicity warnings, interactions, and precautions.Copyright © 2023
ABSTRACT
Introduction : Acute gastroenteritis is a typical disorder that accounts for 8-12% of pediatric outpatient visits. Campylobacter and Salmonella infections account for about 8.4% and 11% of global diarrhea cases. Due to the importance of these bacteria in pediatric diseases, the aim of this study was to determine the infectious rate of Salmonella and Campylobacter species and also the frequency of the gene encoding Cytholethal distending toxin in children with community-acquired diarrhea. Materials and Methods: Stool samples of children under 5 years of age with diarrhea were collected. The samples were related to children referred to hospitals in Hamadan, Ardabil, Bandar Abbas and two hospitals in Tehran. DNA was extracted from the samples using a DNA extraction kit from stool. The presence of Campylobacter in the studied samples was detected by polymerase chain reaction using specific primers. A control stool sample was spiked with 10-fold dilution of C. jejuni suspension for LOD (detection limit determination) measurement. Results: In this study, PCR results showed a LOD of 100 CFU per gram in the spiked feces sample. Accordingly, out of 144 fecal samples of children with acute diarrhea, one case was positive for Campylobacter jejuni;this sample was also positive for the presence of cdtB gene. Presence of Salmonella was confirmed in two samples of the patients (1.4%). Conclusion: Low prevalence of Campylobacter and Salmonella was detected in symptomatic children under 5 years of age during the Covid-19 pandemic. Examination of these samples for viruses and other microbial agents can clarify the etiology of diarrhea in children referred to the hospitals.
ABSTRACT
INTRODUCTION: Coronavirus disease 2019 (COVID-19) mainly involves the respiratory system but can also affect the digestive system and cause several gastrointestinal manifestations. Acute pancreatitis has been reported as one of the rare presentations of COVID-19. This study aimed to systematically review case reports on COVID-19-associated acute pancreatitis. METHODS: Publications were retrieved through a comprehensive search in four databases on October 1, 2021. Eligible ones that demonstrated the potential association of acute pancreatitis and COVID-19 were included for data extraction. RESULTS: After screening 855 citations, 82 articles containing 95 cases were included, and their data were extracted. The most common presentation was abdominal pain (88/95, 92.6%), followed by nausea/vomiting (61/95, 64.2%). Mortality was reported in 10.5% of cases. The initial presentation was acute pancreatitis, COVID-19, and concomitant in 32.6% (31/95), 48.4% (46/95), and 18.9% (18/95) of cases, respectively. Among the included cases, acute pancreatitis severity was associated with ICU admission, COVID-19 severity, and the outcome. Also, the initial presentation was associated with COVID-19 severity (P values Ë0.05). CONCLUSIONS: Current evidence indicates that acute pancreatitis can present before, after, or concomitant with COVID-19. Appropriate investigations should be performed in cases with suspicious clinical presentations. Longitudinal studies should address whether or not, there is a causative relationship between COVID-19 and acute pancreatitis.

Introduction: The transmission of the etiologic virus of COVID-19 (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) is thought to occur mainly via respiratory droplets even though limited evidence has shown the virus can be found in feces and involve the gastrointestinal (GI) tract. The aim of this study was to assess if patients with COVID-19 present with fecal shedding of SARS-CoV-2, intestinal inflammation or changes in their microbiota. Method(s): This was a prospective cohort study that included outpatients that presented with symptoms of COVID-19 and were tested using a nasopharyngeal PCR test (NPT). Two cohorts were selected: one with a (1) NPT and a control group with a (-) NPT. Stool and a clinical data were collected at baseline and then, days 14, 28 and 42. SARS-CoV-2 viral loads were measured in stool using PCR and stool microbiome was analyzed using 16S rRNA gene sequencing (V3/V4 region). Fecal calprotectin levels were also measured on each sample and used as a surrogate marker of intestinal inflammation. Result(s): 101 patients were recruited (410 total samples). Of those, 55 had a (1) COVID-19 NPT. Most patients with a (1) COVID-19 NPT PCR had a detectable fecal viral load (71%). Among these patients, 23 (55%) had detectable viral stool loads only at baseline, 12 through day 14, 6 through day 28 and 1 through day 42. One patient had a (-) NPT but detectable SARS-CoV-2 in the baseline stool sample. Subjects with (1) NPT presented more commonly with myalgias (p=0.02), dysgeusia (p=0.019) and anosmia (p=0.03) when compared to those with (-) NPT but there were no differences in any other symptoms including GI manifestations.Within the group with a (1) NPT, those patient with detectable SARS-CoV-2 in the stool were younger but no differences were seen in demographic, symptoms, or fecal calprotectin levels (Table). There was no correlation between fecal SARS-CoV-2 loads and fecal calprotectin levels (rho: 0.007 [p=0.95]). Patients with a (1) NPT PCR had higher evenness when compared to those that tested (-) for a NPT PCR. However, no differences were seen in other alpha or beta diversity (Figures 1A and 1B, respectively). Conclusion(s): Even though intestinal viral shedding of SARS-CoV-2 in patients with COVID-19 is common, these patients do not present with evidence of inflammation of the GI tract, a significantly disrupted gut microbiome or a higher incidence of GI symptoms when compared to patients with respiratory symptoms and no COVID-19.
ABSTRACT
Acute respiratory viral infections (ARVI) play an important role in morbidity formation among children. At the same time, studies about the ARVI etiological structure are not enough. The article presents the results of structure analyses of ARVI in children with severe and moderate degrees of disease hospitalized in the children's clinical hospital of Novosibirsk for the period 2015-2018. This research aimed to analyze the morbidity of acute respiratory viral infections with the estimation of a causal virus in children admitted to the hospital for the period 2015-2018. Material and methods. In this study, 1137 children aged between 0 and 15 years were examined. In order to determine the etiological factor in children with damage of the upper or lower respiratory tract, by using the method of RT-PCR (AmpliSensARVI-screen-FL test systems (InterLabService, Russia), mucus from the nose and throat was examined for the presence of genetic material of viruses that cause ARVI (influenza A and B viruses, parainfluenza viruses of types 1-4, respiratory syncytial virus, metapneumovirus, four types of human coronavirus, rhinovirus, adenovirus, and bocavirus). Results. The research found that the most frequently detected pathogens are respiratory syncytial virus (23.52%), influenza A and B viruses (19.73%) and rhinovirus (19.21%). Observe the dynamics some fluctuations in the detection of mentioned viral agents and increasing of mixed infections were detected. In addition, the importance of respiratory and gastrointestinal tract combined lesions, particularly for infants and preschool - age children has been noted. Conclusion. The distribution of respiratory viruses in children with severe ARVI who required hospitalization was assessed. It was shown the significance of the respiratory syncytial infection virus, influenza virus and rhinovirus in the etiological structure of hospitalized children of different ages that damage not only the respiratory tract, but also to the gastrointestinal tract. This is an important factor in optimizing the diagnosis, treatment and prevention of viral infections in children.Copyright © Infectious Diseases: News, Opinions, Training 2021.
ABSTRACT
Coinfection caused by bacteria, parasites, or viruses complicates almost all feline panleukopenia virus (FPV) infections. Pathogens that colonize the gastrointestinal tract, Clostridium perfingens, Clostridium piliforme, Cryptosporidium spp, Giardia spp, Tritrichomonas fetus, canine parvovirus type 2,Salmonella sp., feline coronavirus, feline bocavirus, and feline astrovirus were isolated in the presence of FPV infection. Complex mechanisms between viruses, bacteria, protozoa, and hosts contribute to the pathogenesis and severity of coinfection. Prompt and accurate diagnosis, vaccination precautions, and appropriate treatment play important roles in reducing morbidity and mortality. This article outlines the etiology, pathogenesis, diagnosis, prevention, and treatment that can help veterinarians and pet owners improve their knowledge of managing the diseases.
ABSTRACT
Since the late 2019 months' pandemic of Corona Virus Disease-2019 (COVID-19), it has spread globally and claimed abundant lives due to its expeditious interpersonal transmission and high mortality rate. Early studies showed that the upper aerodigestive tract procedures had the highest rates of nosocomial spread due to high viral load in upper respiratory and pharyngeal secretions. Between March 10 and April 10, 2020, a total of 28 rigid endoscopies were performed under general anesthesia for the removal of esophageal foreign bodies at our center. All the patients were screened on admission for symptoms of COVID-19 and a chest CT scan was performed and they were later followed up for further investigations. No patient had symptoms of COVID-19 (fever, cough, and dyspnea) on admission, and only one patient (3.57 %) had a suspicious CT scan for COVID-19. The mean age of 27 asymptomatic cases, including 14 men and 13 women, was 45.2 years old. Their average hospital stay was 0.8 days. all patients were later interviewed, inspected, and closely observed for any upcoming symptoms which would raise suspicion for COVID-19 during isolation. Of the 27 patients who cooperated, none showed COVID-19 symptoms. What makes this experiment prominent is that with suitable plans in a careful and precautionary manner, we can provide first-rate care for patients and meanwhile protect physicians during this pandemic promptly.Copyright © 2023 Tehran University of Medical Sciences.
ABSTRACT
Coronaviruses are a large family of single-stranded ARN viruses that infect a wide variety of animals, including humans. The SARS-CoV-2 virus, which is responsible for the disease called COVID-19, has infected 27,249,308 people and caused 890,971 deaths worldwide until September 7, 2020. Considering the genetic similarities between SARS-CoV-2 and the epidemic coronaviruses SARS-CoV and MERS, presumably they share tropisms for specific cell lines and systemic conditions. The clinical and paraclinical characteristics of this new virus have been described in detail at the pulmonary level, although there is increasing evidence that it is a multisystemic agent. In the present work, we describe the extrapulmonary manifestations of COVID-19 reported to date, including hematological, cardiovascular, neurological, renal, muscular, ophthalmological, endocrine-metabolic, gastrointestinal, hepatobiliary, cutaneous and in special populations: pediatric (including multisystemic inflammatory syndrome) and pregnant women. It is essential to know the systemic complications of SARS-CoV-2 infection when managing these patients, given the potential risk to life of the most serious manifestations. Therefore, it is advisable to consider them in a targeted manner and provide timely treatment as far as possible.Copyright © 2022 Comunicaciones Cientificas Mexicanas S.A. de C.V..

ABSTRACT
Introduction: Cystic Fibrosis (CF) centers globally increased the number of telehealth clinics during the Covid-19 pandemic and developed processes utilizing telemedicine to replace a standard clinic visit. Whether these new approaches provide an opportunity to improve patients' clinical condition need further investigations. Aims and objectives: To assess the short-term clinical impact of using the NuvoAir Home platform to monitor children and adolescents with CF at home for six months as part of a virtual model of care. Method(s): The NuvoAir Home platform consists of a smartphone application, Bluetooth spirometer and clinician portal. Patients and/or parents were trained to use the platform and asked to do home spirometry monthly. Cystic Fibrosis Questionnaire-Revised (CFQ-R) was collected at the time of study entry and after six months. We calculated the percentage of change between "pre" and "post" conditions of the variables. Result(s): Sixteen children and adolescent CF patients from Federico II Hospital, Naples, Italy (9 females;mean age 16.3+/-0.9;5 homozygous for delta F508;FEV1 79.5+/-26.2 % predicted;FVC 91.6+/-23.6 % predicted;BMI 21.5+/-3.8) were recruited from June 2021. All patients had completed six months follow-up. CFQ-R revealed higher scores indicating a higher patient-reported quality of life with regard to "health perception" + 3%, "social limitations" + 11%, "digestive symptoms" + 6%. We observed a 2 % improvement from baseline in FEV1 % predicted. There was no difference in pulmonary exacerbation versus the previous year. No changes of medical treatment were reported during that time. Conclusion(s): Digital technology for home monitoring in children and adolescents with cystic fibrosis led to improved quality of life and lung function.
ABSTRACT
Introduction: The relationship between the severity of SARS COV 2 infections and chronic respiratory diseases remains controversial Aim: To identify the characteristics of SARS COV 2 infection in patients suffering from chronic respiratory diseases Method: a retrospective, and descriptive study including 1190 patients that were hospitalized for COVID19, from March 2020 to March 2021. Result(s): Among 1190 patients, one hundred and nineteen (10%) had chronic respiratory disease. Male gender was dominant. Asthma and COPD were the most identified conditions (N=64) and (N=47) respectively. Other comorbidities were identified like hypertension (37,8%) and diabetes (12,6%). The most described symptoms were dyspnea (69.8%), cough (52.9%), and digestive symptoms (20.16%). The most common chest CT findings were ground-glass opacities (68.65%) with moderate (31%) to severe (28,5%) scores. More severe CT scores were identified among asthmatics (P = 0.009). Death occurred in 19.6% of cases and 17% of patients needed intensive care transfer, non-invasive ventilation and they suffered from COPD in 70% of cases. However, we notice that asthma was related to severe radiological scores compared to COPD, probably due to bacterial infection because of inhaled corticosteroid use but with a better prognosis. Hypercapnia in COPD and OHS may worsen the scene. Conclusion(s): Many studies proved that asthmatics are less prone to have severe clinical forms of COVID19. It is probably thanks to corticosteroid use. More studies are needed to explain the lack of these protective effect in other inhaled corticosteroid users.
ABSTRACT
The advent of the COVID-19, specialists are increasingly encountering previously unknown pathological conditions in their practice. For some time, we have believed, that COVID-19 in children is most often mild and asymptomatic. However, with the passage of time and. the accumulation, of the experience, it became obvious that the new infectious disease it will be quite severe in children. Differential diagnosis of multiple organ disorders in children during the COVID-19 pandemic should, be primary carried out with the Multisystem. Inflammatory Syndrome in Children, associated, with COVID-19 (MIS-C), as well as Long-COVID-19. According to published, data, the manifestations of these conditions are due to frequent lesions of the gastrointestinal tract (60-100%), cardiovascular (80%), nervous (29-58%) and respiratory (21-65%) systems. At present, there is no exact idea of these pathological conditions, the criteria for their diagnosis and. the tactics of managing children, not only at the stage of diagnosis, but also at the stage of observation. The authors present a diagnostically complex clinical case describing the development of multiple organ damage in a 7-year-old. child, after contact with a mother who was sick with COVID-19. The data on the course features, the results of the examination and. the difficulties of differential diagnosis of this case with other diseases with a similar clinic are summarized.Copyright © 2022 Authors.

ABSTRACT
Livestock products supply about 13 percent of energy and 28 percent of protein in diets consumed worldwide. Diarrhea is a leading cause of sickness and death of beef and dairy calves in their first month of life and also affecting adult cattle, resulting in large economic losses and a negative impact on animal welfare. Despite the usual multifactorial origin, viruses are generally involved, being among the most important causes of diarrhea. There are several viruses that have been confirmed as etiological agents (i.e., rotavirus and coronavirus), and some viruses that are not yet confirmed as etiological agents. This review summarizes the viruses that have been detected in the enteric tract of cattle and tries to deepen and gather knowledge about them.Copyright © 2021 by the authors.

ABSTRACT
Background: Various digestive symptoms caused by COVID-19 are frequently reported. This study aims to describe the most frequent digestive signs in patients with COVID-19, the relationship between the severity of digestive symptoms and some serological markers associated with liver manifestation, the detection of SARS-CoV-2 in a stool sample, and the mortality rate of those patients. Material(s) and Method(s): A descriptive cross-sectional study on 100 confirmed COVID-19 cases with digestive and hepatic manifestation in one center (Fallujah Teaching Hospital), Anbar governorate, Iraq, during a period of study. Questioner's data were formed for all patients regarding age, sex, and comorbidities such as diabetes and hypertension. Liver function enzymes such as alanine aminotransferase (ALT), aspartate aminotransferase, alkaline phosphatase, total bilirubin (TBIL), and direct bilirubin and haematological parameters such as ferritin D-dimer, C-reactive protein (CRP), albumin, amylase, leukocyte count, and prothrombin time were used. SARS-CoV-2 prevalence in stool is determined using reverse transcription polymerase chain reaction according to manufacturer's instructions. The mortality rate of patients with COVID-19 was also determined. Data were followed up until April 22, 2022. Result(s): Patients with digestive symptoms who had COVID-19 had an average age of 45.03 (SD 20.078), 52 (52%) were men, and 48 (48%) were women. No statistically significant variances were observed in the severity of digestive symptoms among age groups. The three digestive symptoms that patients with COVID-19 experienced most frequently were fatigue, fever, and abdominal colic. SARS-CoV-2 was detected in the stool of 11% of the patients with COVID-19 with digestive signs. The COVID-19 mortality rate was 9%. Statistically, significant variance was observed in ALT (P value 0.01) and TBIL (P value 0.0027) levels between mild, moderate, and severe gastrointestinal (GI) diseases. The levels of CRP varied considerably among those with mild, moderate, and severe GI conditions (P value 0.0182, according to the findings). In mild, moderate, and severe GI disorders, ferritin levels differed considerably (P value 0.05). Conclusion(s): The faecal sample with a nasopharyngeal swab is needed to confirm COVID-19 diagnosis;hepatic manifestations are connected with increased COVID-19 mortality in individuals with digestive symptoms.Copyright © 2022 Wahab, Khalil, Majeed, licensee HBKU Press.
