Immunoglobulin G Antibody Immune Response Profile Following Infection With SARS-CoV-2 in COVID-19 Egyptian Patients

Immunoglobulin G Antibody Immune Response Profile Following Infection With SARS-CoV-2 in COVID-19 Egyptian Patients

Recruiting
16-90 years
All
Phase N/A

Overview

The objective of this study is to detect the evidence on the immune response following acute SARS-CoV-2 infections. the study will report the profile of IgG specific antibodies levels to SARS-CoV-2 infection found in recovered coronavirus disease (COVID-19) patients after infection for both symptomatic and asymptomatic patients.

Description

A total of 30 COVID-19 patients for the study will be enrolled. All the patients enrolled were confirmed to be infected with SARS-CoV-2 by RT-PCR assay for nasal and pharyngeal swab specimens.

For the study, serum samples of the 30 patients will be collected and will be investigated for the detection rate for immunoglobulin G (IgG). The first sample will be collected 2 weeks after the second negative RT-PCR assay for nasal and pharyngeal swab specimens and 6 samples will be collected after that for 6 months later; one serum sample tested every month for 6 months after.

The following questions will be addressed:-

  1. What proportion of confirmed cases develops specific IgG antibodies to SARS-CoV-2?
  2. How long is the duration of detection of serum IgG antibodies and antibody titres over time following infection with SARS-CoV-2?

Eligibility

Inclusion Criteria:

  • patients with recent COVID- 19 infection(2 weeks after the second negative RT-PCR assay)

Exclusion Criteria:

  • patients on immune-suppressive therapy
  • patients with immunological disease

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
