Ultrastructural Characterization of Human Bronchial Epithelial Cells during SARS-CoV-2 Infection: Morphological Comparison of Wild-Type and CFTR-Modified Cells.

SARS-CoV-2 replicates in host cell cytoplasm. People with cystic fibrosis, considered at risk of developing severe symptoms of COVID-19, instead, tend to show mild symptoms. We, thus, analyzed at the ultrastructural level the morphological effects of SARS-CoV-2 infection on wild-type (WT) and F508del (ΔF) CFTR-expressing CFBE41o- cells at early and late time points post infection.

CFTR Modulation Reduces SARS-CoV-2 Infection in Human Bronchial Epithelial Cells.

People with cystic fibrosis should be considered at increased risk of developing severe symptoms of COVID-19. Strikingly, a broad array of evidence shows reduced spread of SARS-CoV-2 in these subjects, suggesting a potential role for CFTR in the regulation of SARS-CoV-2 infection/replication. Here, we analyzed SARS-CoV-2 replication in wild-type and CFTR-modified human bronchial epithelial cell lines and primary cells to investigate SARS-CoV-2 infection in people with cystic fibrosis.

Prevalence of and Short-term Changes in Conjunctival Manifestations Among Patients With SARS-CoV-2 Infection.

This cohort study assesses the prevalence of SARS-CoV-2–related conjunctival manifestations and conjunctival swab positivity on hospital admission and 3 days thereafter for patients not receiving anti-inflammatory treatment.

Assessment of SARS-CoV-2 IgG and IgM antibody detection with a lateral flow immunoassay test.

The dramatic impact of SARS-CoV-2 infection on the worldwide public health has elicited the rapid assessment of molecular and serological diagnostic methods. Notwithstanding the diagnosis of SARS-CoV-2 infection is based on molecular biology approaches including multiplex or singleplex real time RT-PCR, there is a real need for affordable and rapid serological methods to support diagnostics, and surveillance of infection spreading. In this study, we performed a diagnostic accuracy analysis of COVID-19 IgG/IgM rapid test cassette lateral flow immunoassay test (LFIA) assay.

Concomitant Infection of and Intestinal Parasites in Adults Attending a Referral Centre for Parasitic Infections in North Eastern Italy.

Background: and intestinal parasites are estimated to infect with high burden worldwide. However, their concomitant infections are poorly determined in industrialized countries, such as Italy. In this study we aim at describing the presence of as well as the proportion of coinfections with intestinal parasites among subjects who attended a referral center for tropical diseases in Northern Italy.
