Abstract How frequently autoantibodies against angiotensin‐converting enzyme 2 (ACE2) occur in patients infected by SARS‐CoV‐2 is understudied and limited to investigations on a small sample size. The presence of these antibodies may contribute the long‐lasting effects COVID‐19 observed some individuals, particularly if IgG‐class would emerge patients. This study assessed prevalence IgG ACE2 1139 with examined their relationship severity, demographic characteristics, status vaccination...

Respiratory Syncytial Virus (RSV) is a prevalent pathogen of the respiratory tract, posing significant threat to individuals with compromised immune systems, particularly elderly and neonates in hospital settings. The primary objective this study was identify specific period within epidemic season during which healthcare providers can anticipate an increased incidence RSV infections characterize Poland. Molecular biology techniques were employed diagnose samples at Sanitary Stations National...

The aim of the study was to determine level anti-hemagglutinin antibodies in serum patients during 2021/2022 epidemic season Poland. A total 700 sera samples were tested, divided according age into 7 groups: 0-4 years age, 5-9 10-14 15-25 26-44 45-64 and ≥65 100 collected from each group. Anti-hemagglutinin antibody levels determined using haemagglutination inhibition assay (OZHA). results obtained confirm presence for antigens A/Victoria/2570/2019 (H1N1) pdm09, A/Cambodia/e0826360/2020...

There is evidence that vaccination against seasonal influenza can improve innate immune responses to COVID-19 and decrease disease severity. However, less known about whether it could also impact the humoral immunity in SARS-CoV-2 infected patients. The present study aimed compare specific (IgG antibodies nucleocapsid; anti-N, receptor binding domain; anti-RBD, subunit S2; anti-S2, envelope protein; anti-E) between non-hospitalized, unvaccinated, mild convalescent patients who were not...

The present study assesses the seroprevalence of antibodies against seasonal human alphacoronaviruses 229E and NL63 among adult patients infected with SARS-CoV-2, its association humoral response to SARS-CoV-2 infection severity, influenza vaccination. A serosurvey was conducted quantify presence IgG nucleocapsid (anti-229E-N) (anti-NL63-N), anti-SARS-CoV-2 (against nucleocapsid, receptor-binding domain, S2 envelope, papain-like protease) for 1313 Polish patients. anti-229E-N anti-NL63 in...

The effects of immunization with subunit inactivated quadrivalent influenza vaccine (QIV) are not generally well assessed in the elderly Polish population. Therefore, this study evaluated vaccine-induced antibody response and its determinants.Consecutive patients ≥ 55 years old, attending a Primary Care Clinic Gryfino, Poland, received QIV (A/Michigan/ 45/2015(H1N1)pdm09, A/Singapore/INFIMH-16-0019/2016 (H3N2), B/Colorado/06/2017, B/Phuket/ 3073/2013) between October-December 2018....
