Aim: The aim of this study is to determine the frequency of celiac disease (CD) in a group of children with juvenile rheumatoid arthritis (JRA) and determine the correlation between the presence of the serologic markers and the histological diagnosis of CD.
Patients And Methods: Forty-two children (24 females) with JRA, aged between 5-15 years underwent study of serologic markers for CD (gliadin-IgA, gliadin-IgG, reticulin and endomysium-IgA antibodies). Endoscopic intestinal biopsy was performed in patients who had positive serologic markers for CD. The diagnosis of CD was based on the classic finding of villous atrophy and crypt hypertrophy.
Results: Eighteen patients (42.8%) had serologic markers for CD; ten of them with a systemic form, five with a polyarticular form and three with a pauciarticular form of JRA. Levels of AGA -IgG were high in 14 patients (77.8%), four patients (22.2%) had high levels of AGA-IgA and seven patients (38.9%) had anti-endomysium antibodies (AEA). One patient had anti-reticulin antibodies (ARA) 5.5%. Sixteen patients underwent intestinal biopsy; in only one patient with AEA antibodies (2.38%), biopsy revealed typical finding of CD. The patient with CD showed improvement in both growth parameter as well as articular symptoms after starting gluten-free diet
Conclusion: Our study shows that the screening for silent CD among children with JRA may be useful. Those patients with AEA need further follow up since these antibodies are quite sensitive and specific for CD.

: ACE (angiotensin-converting enzyme) is considered a serological marker of sarcoidosis as elevated levels have been reported in 30-80% of patients. However, elevated ACE levels are also encountered in other medical conditions, and the clinical correlation between ACE levels and disease activity in sarcoidosis is disputable as well. To determine the significance of elevated ACE levels in the diagnosis and follow-up of sarcoidosis patients.

Background: The longitudinal study was conducted over the initial 2 years of the COVID-19 pandemic, spanning from June 2020 to December 2022, in healthcare workers (HCWs) of the Thomayer University Hospital. A total of 3892 blood samples were collected and analyzed for total nucleocapsid (N) antibodies. The aim of the study was to evaluate the dynamics of N antibodies, their relationship to the PCR test, spike (S) antibodies, interferon-gamma, and prediction of reinfection with SARS-CoV-2.

Introduction: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients are severely immunocompromised and susceptible to bacterial, viral, and fungal infections. Despite improved anti-microbial prophylaxis and preemptive strategies, bacterial bloodstream infections (BSIs) occur frequently in allo-HSCT recipients and are associated with increased morbidity and mortality. Cytomegalovirus (CMV) and Epstein Barr virus (EBV) are the most relevant viruses following allo-HSCT and remain major concerns.

Refractory invasive fungal disease is a significant clinical problem, with high morbidity, mortality and costs. The complex causes of refractory infection include breakthrough infection due to antifungal resistance (both innate and acquired), suboptimal therapy and impaired immune responses in critically ill or immunocompromised patients. This case series details three reports on the identification and management of refractory fungal infections, two cases of azole resistance and one case of resistant candidiasis, highlighting the importance of accurate diagnosis, monitoring, implementation of biomarkers (serological markers, PCR), antifungal susceptibility testing and antifungal stewardship to optimise management and minimise risks of emergence of drug resistance.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent inflammation of the synovial joints, leading to cartilage and bone destruction. This study aimed to evaluate the diagnostic utility of specific microRNAs (miRNAs) as potential biomarkers for RA. The study was conducted on 60 patients with RA disease along with 20 control participants.
