Longitudinal Changes in Selected Gut Microorganisms During Gluten-Free Diet in Pediatric Coeliac Disease

Aleksandra Zieba, Kamil Drożdż, Agnieszka Krawczyk

Abstract Alterations in gut microbiota have been reported in coeliac disease (CeD). However, longitudinal evidence distinguishing disease-related effects from diet-driven changes after gluten-free diet initiation remains scarce, particularly in pediatric cohorts. The present study aimed to evaluate time-dependent changes in selected intestinal …

Gut bacterial and fungal signatures in relation to human leukocyte antigen-DQ2/DQ8 in children with celiac disease and siblings

Dominika Salamon, Agnieszka Krawczyk, Barbara Zapała, Mariusz Duplaga et autres

BACKGROUND The presence of human leukocyte antigen (HLA)-DQ2 and/or HLA-DQ8 alleles is necessary but not sufficient for the development of celiac disease (CeD). This suggests that additional environmental and biological factors, including bacteria and, above all, the still rarely studied fungal gut …

Clinical Associations and Coexistence of Polyomavirus DNAemia with EBV and CMV in Pediatric Hematology/Oncology Patients, Including HCT Recipients—A Pilot Study

Tomasz Bogiel, Mateusz Rzepka, Dagmara Depka, Patrycja Zalas‐Więcek et autres

Polyomaviruses (BKPyV and JCPyV) and herpesviruses (EBV, CMV) usually infect people during childhood, and may be associated, in some clinical states, with immunocompromised individuals. The aim of this study was to investigate the occurrence and coexistence of polyomavirus (BKPyV and JCPyV) and …

Effects of fecal microbiota transplantation on the abundance and diversity of selected fungal and archaeal species in the gut microbiota in the rat model of schizophrenia

Agnieszka Krawczyk, Tomasz Kasperski, Tomasz Gosiewski, Agnieszka Nikiforuk et autres

BACKGROUND: The gut microbiome has been increasingly recognized for its potential role in schizophrenia through gut-brain interactions involving immune, neural, and metabolic pathways. This pilot study evaluated the impact of fecal microbiota transplantation (FMT) on the abundance and variability of selected fungal …

Prevalence and Variability of Helicobacter pylori Clarithromycin Resistance Mutations in Pediatric Patients in Poland: A Genotypic Analysis Using the Bosphore Genotyping Kit

Tomasz Bogiel, Anna Szaflarska‐Popławska, Agnieszka Krawczyk

Background: Helicobacter pylori is a Gram-negative bacterium responsible for various gastrointestinal diseases, including peptic ulcers and gastric cancer. Despite available antibiotic therapies, increasing resistance to clarithromycin—a key antibiotic in eradication regimens—poses a significant challenge. This resistance is primarily linked to point mutations …

An alternative method for SARS-CoV-2 detection with use modified fluorescent in situ hybridization

Agnieszka Sroka-Oleksiak, Agnieszka Krawczyk, Katarzyna Talaga-Ćwiertnia, Dominika Salamon et autres

The real-time reverse-transcriptase polymerase-chain-reaction (rRT-PCR) tests are the gold standard in detecting SARS-CoV-2 virus infection. However, despite high sensitivity and specificity, they have limitations that in some cases may result in false negative results. Therefore, it is reasonable to search for additional …

Are there new biomarkers of the gastroduodenal microbiota useful in the diagnosis of coeliac disease in children? A pilot study

Dominika Salamon, Kinga Kowalska‐Duplaga, Agnieszka Krawczyk, Mariusz Duplaga et autres

The changing of microbiome could precede the development of coeliac disease (CeD). We compared the bacterial profile of microbiota of tissues collected simultaneously from the stomach and duodenum in newly diagnosed patients with CeD. Biopsies were collected from 60 children and adolescents …
