Brief Summary:

The study includes 2 sub-projects.

Sub-project 1: The aim is to evaluate the expression of receptors and activating proteases mediating SARS-CoV-2 entry and spreading in the local population of Ticino.

Sub-project 2: The aim is to investigate the association between the HSD3B1 gene variations and outcome of COVID-19 in the local population of Ticino.


Condition or disease Intervention/treatment
Covid19 Genetic: Expression of receptors and activating proteases Genetic: Polymorphism of the HSD3B1

Detailed Description:

Sub-project 1:

This is an observational retrospective study that aims to evaluate the expression of receptors and activating proteases mediating SARS-CoV-2 entry and spreading in the local population of Ticino. The level of expression of these factors will be compared between infected and non-infected subjects. The sub-project will examine RNA samples from nasopharyngeal swabs taken from subjects tested for COVID-19.

Sub-project 2:

This is a haplotype- and diplotype-based case-control retrospective study that aims to investigate the association between the HSD3B1 gene variations and outcome of COVID-19 in the local population of Ticino. The gene status of HSD3B1 will be defined and compared between two groups of patients: the patients who experienced a severe SARS-CoV-2 infection (severe pulmonary insufficiency, ICU admission, eventually death) and the group with a mild-moderate COVID-19 disease without pulmonary insufficiency and oxygen need.

Group/Cohort Intervention/treatment
Patients tested for COVID-19
The nasopharyngeal swabs taken from patients tested for Covid-19 who resulted infected and non-infected will be analyzed to evaluate the expression of receptors and activating proteases mediating SARS-CoV-2.
Genetic: Expression of receptors and activating proteases
Level of expression of the mRNA of the genes encoding ACE2, TMPRSS2, TMPRSS4 and AR along with reference genes (beta-actin and EPCAM) in nasopharyngeal swabs taken from patients tested for COVID-19

Patients with mild-moderate and severe SARS-CoV-2 infection
Formalin-fixed paraffin will be analysed to determine the association between polymorphism of the HSD3B1 gene and outcomes in COVID-19 affected patients
Genetic: Polymorphism of the HSD3B1
Formalin-fixed paraffin embedded tissue blocks will be amplified using polymerase chain reaction (PCR) based experiments followed by direct sequencing (Sanger sequencing)




Primary Outcome Measures :
  1. Expression of receptors and activating proteases [ Time Frame: 1 year ]
    Determination of the level of expression of the mRNA genes

  2. Prevalencen of olymorphisms of the HSD3B1 [ Time Frame: 1 year ]
    Determination of the prevalence of polymorphisms of the HSD3B1 patients with severe and mild-moderate SARS-CoV-2 infection

  3. Association of polymorphisms of the HSD3B1 [ Time Frame: 1 year ]
    Evaluation of the association of polymorphisms of the HSD3B1 with clinico-pathological parameters


Biospecimen Retention:   Samples With DNA

Sub-project 1: nasopharyngeal swabs

Sub-project 2: tissue samples
