Current insight into enteropathogens in flare-up ulcerative colitis. An observational study.

OBJECTIVE: Incidence of ulcerative colitis is globally increased. Enteric infections and their role in ulcerative colitis flares present a common health problem and a unique clinical challenge. We aimed to identify enteropathogens in flared ulcerative colitis patients and their antimicrobial susceptibilities and relation with the disease activity. METHODS: Stool samples were collected from 95 patients with ulcerative colitis (17 inactive cases and 78 active cases) according to the Mayo score assessment of ulcerative colitis severity. Enteropathogens were examined using an automated VITEK2 system and FilmArray gastrointestinal pathogen panel. RESULTS: Enteric infections were found in 81 patients (85.3%) with a significantly higher percentage in active ulcerative colitis (96.2% vs. 35.3%, P  < 0.001). In 78 symptomatic patients, (78.7%) of bacteria as enteroaggregative and enteropathogenic E. coli , (11.5%) parasitic as Cryptosporidium and (7.7%) viral as Norovirus were the most detected microbial pathogens. Mixed, multidrug-resistant organisms (MDROs) and opportunistic infections were reported in 70.7%, 52.9% and 46.7% respectively. Raoultella ornithinolytica was reported for the first time as an enteropathogen in ulcerative colitis flare. Multiple organisms, MDROs, extended-spectrum beta-lactamases-producing and AmpC-resistant bacteria were significantly associated with disease severity. CONCLUSION: Identifying enteropathogens especially opportunistic and MDR organisms as a cause of ulcerative colitis flare-ups is a matter of worry increasing their diagnostic and therapeutic burden. Periodic studies evaluating changes in microbial profiles and their antimicrobial susceptibilities are needed to achieve antibiotic stewardship and improve management.

Does herpes simplex virus have a role in the pathogenesis of systemic lupus erythematosus in Egyptians?

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by immune mediated tissue damage affecting a wide range of organs. The pathogenesis of SLE is complex. Infectious agents, including viruses, can act as environmental triggers, inducing or promoting onset and exacerbations of autoimmune disease in genetically predisposed individuals. Viral infections may be involved in the pathogenesis of SLE. To date, there is no published data about role of herpes simplex virus (HSV) in pathogenesis of SLE in Egyptian population. This study was designed to investigate a possible role of HSV in pathogenesis of SLE and its relation to disease activity. This study included 90 SLE female patients and 83 apparently healthy age-matched female subjects. SLE disease activity was assessed using SLEDAI-2K score. Qualitative assessment of anti-HSV antibodies (HSV1/2 IgM and IgG) was performed using ELISA kits. There was no statistically significant difference in frequency of HSV1/2 IgG positive test between SLE patients (97.6%) and control subjects (94.4%). There was a statistically significant increase in frequency of HSV1/2 IgM positive test in SLE patients compared to control subjects (P < 0.001). There was no difference in the frequency of HSV1/2 IgM and HSV1/2 IgG positive test results between SLE patients with higher disease activity score (60% and 95.6%, respectively) and those with lower disease activity score (60% and 93.3%, respectively). High prevalence of HSV1/2 IgG antibodies was observed among Egyptians. The lack of significant difference in frequency of HSV1/2 IgG between SLE patients and control subjects may indicate that HSV is not involved in SLE pathogenesis. Also, HSV infection may have no role in SLE disease exacerbation due to the absence of significant difference in the frequency of HSV1/2 IgM and HSV1/2 IgG antibodies in SLE patients with higher disease activity compared to those with lower disease activity.

Whole-genome sequencing of Egyptian multidrug-resistant Klebsiella pneumoniae isolates: a multi-center pilot study.

Multidrug-resistant (MDR) Klebsiella pneumoniae is a common infectious pathogen. We performed whole-genome sequencing (WGS) of 39 randomly selected, geographically diverse MDR K. pneumoniae from nine Egyptian hospitals. Clinical sources, phenotypic antibiotic resistance, and hyper-mucoviscosity were documented. WGS data were epidemiologically interpreted and tested for the presence of antibiotic resistance and virulence genes. Based on WGS data, we identified 18 classical multi-locus sequence types (MLST), the most common type being ST101 (23.1%) followed by ST147 (17.9%). Phylogenetic analyses identified small numbers of closely related isolates in a few of the centers, so we mostly documented independent nosocomial acquisition or import from public sources. The most common acquired resistance gene found was blaCTX-M-15, detected in 27 isolates (69.2%). Carbapenemase genes encountered were blaNDM-1 (n = 13), blaNDM-5 (n = 1), blaOXA-48 (n = 12), blaOXA-181 (n = 2), and blaKPC2 (n = 1). Seven strains (18%) contained more than a single carbapenemase gene. While searching for virulence-associated genes, sixteen wzi alleles were identified with wzi137, wzi64, and wzi50 most commonly found in ST101, ST147, and ST16, respectively. Yersiniabactin was the most common virulence factor (69.2%). Hyper-mucoviscosity was documented for 6 out of 39 isolates.This is the first genomic study of MDR K. pneumoniae from Egypt. The study revealed a clear spread of well-known international clones and their associated antimicrobial resistance and (hyper)virulence traits. The clinical situation in Egypt seems to reflect the scenario documented in many other countries and requires close attention.

Determinants of Obtaining COVID-19 Vaccination among Health Care Workers with Access to Free COVID-19 Vaccination: A Cross-Sectional Study.

INTRODUCTION: Despite global efforts to contain the illness, COVID-19 continues to have severe health, life, and economic repercussions; thus, maintaining vaccine development is mandatory. Different directions concerning COVID-19 vaccines have emerged as a result of the vaccine's unpredictability. AIMS: To study the determinants of the attitudes of healthcare workers (HCWs) to receiving or refusing to receive the vaccine. METHODS: The current study adopted an interviewed questionnaire between June and August 2021. A total of 341 HCWs currently working at Assiut University hospitals offered to receive the vaccine were included. RESULTS: Only half of the HCWs (42%) accepted the COVID-19 vaccine. The most common reason that motivated the HCWs was being more susceptible than others to infection (71.8%). On other hand, the common reasons for refusing included: previously contracted the virus (64.8%); did not have time (58.8%); warned by a doctor not to take it (53.8%). Nearly one-third of nonaccepting HCWs depended on television, the Internet, and friends who refused the vaccine for information (p < 0.05). In the final multivariate regression model, there were six significant predictors: sex, job category, chronic disease, being vaccinated for influenza, and using Assiut University hospital staff and the Ministry of Health as sources of information (p < 0.05). CONCLUSION: Misinformation and negative conceptions are still barriers against achieving the desired rate of vaccination, especially for vulnerable groups such as HCWs.
