Antibody tests in detecting SARS-CoV-2 infection: A meta-analysis
(2020)The emergence of Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 made imperative the need for diagnostic tests that can identify the infection. Although Nucleic Acid Test (NAT) is considered to be the gold standard, ... -
A comprehensive analysis of antigen-specific antibody responses against human cytomegalovirus in patients with systemic sclerosis
(2019)Anti-human cytomegalovirus (HCMV) antibodies are considered triggers of systemic sclerosis (SSc), but such a hypothesis has been assessed in limited sub-dominant epitopes. Our aim was to systematically assess the potential ... -
Evaluation of a Direct Immunofluorescent Assay and/or Conjunctival Cytology for Detection of Canine Distemper Virus Antigen
(2018)Canine distemper is a common and potentially lethal multisystemic disease caused by the Canine distemper virus (CDV). We evaluated the diagnostic performance of direct immunofluorescent assay (FA) and cytology to detect ... -
Human cytomegalovirus (HCMV) UL44 and UL57 specific antibody responses in anti-HCMV-positive patients with systemic sclerosis
(2017)The role of human cytomegalovirus (HCMV) has been postulated as a trigger of systemic sclerosis (SSc). The aim of the study was to assess the prevalence of antibodies against HCMV UL44 and UL57 antigens not tested in the ... -
Occult hepatitis B virus infection in Greek patients with chronic hepatitis C and in patients with diverse nonviral hepatic diseases
(2004)Occult hepatitis B virus (HBV) infection has been reported in patients with chronic hepatitis C who are negative for HBV surface antigen (HBsAg). However, the significance of 'silent' HBV in hepatitis C virus (HCV) infection ... -
A prospective epidemiological, clinical, and clinicopathologic study of feline leukemia virus and feline immunodeficiency virus infection in 435 cats from Greece
(2021)Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) are retroviruses causing significant morbidity and mortality in cats. The aim of this study was to describe the epidemiological, clinical and clinicopathologic ... -
Rapid test ag 2019-nCoV (PROGNOSIS, BIOTECH, Larissa, Greece); performance evaluation in hospital setting with real time RT-PCR
(2021)Introduction: Rapid antigen tests (RATs) are convenient for SARS-CoV-2 detection be-cause they are simpler and faster than nucleic acid amplification tests (NAATs). This study aimed to assess the accuracy of a locally ... -
Repeated antigen-based rapid diagnostic testing for estimating the coronavirus disease 2019 prevalence from the perspective of the workers’ vulnerability before and during the lockdown
(2021)Background: No previous study has investigated the SARS-CoV-2 prevalence and the changes in the proportion of positive results due to lockdown measures from the angle of workers’ vulnerability to coronavirus in Greece. Two ... -
Temporal Associations of the SARS-CoV-2 NP Antigen and Anti-Spike Total Ig Levels with Laboratory Parameters in a Greek Cohort of Hospitalized COVID-19 Patients
(2021)Background. The direct effect of SARS-CoV-2 on the lungs results in increased hospitalization rates of patients with pneumonia. Severe COVID-19 patients often develop ARDS which is associated with poor prognosis. Assessing ... -
Understanding covid-19 epidemiology and implications for control: The experience from a greek semi-closed community
(2021)Background: We aimed to estimate the SARS-CoV-2 antigen and antibody seroprevalence in one of the worst-affected by the pandemic semi-closed communities in Greece, Deskati, and evaluate the sociodemographic and clinical ...
