Experimental Use of Convalescent Plasma for Passive Immunization in Current COVID-19 Pandemic in Pakistan in 2020

September 28, 2020 updated by: Hilton Pharma

Experimental Use of Convalescent Plasma of Passive Immunisation In Current COVID-19 Pandemic in Pakistan in 2020 Rationale & Objective: This study would help to gather real-life setting clinical data in local population, ultimately leading to increased evidence based management of the disease condition in the said population.

Eligibility:

  1. informed consent must have been obtained
  2. confirmed COVID-19 cases confirmed by RT-PCR laboratory tests
  3. moderately severe or severe life-threatening COVID-19 related features: a) Moderately Severe disease as defined by the following features: i) Shortness of breath, ii) respiratory rate ≥ 30/min, iii) arterial blood oxygen saturation ≤ 92%, iv) and/or lung infiltrates > 25% within 24 to 48 hours 67 b) Severe Life-threatening disease as defined by: i) respiratory failure, ii) shock, and/or § multiple organ dysfunction

    Exclusion Criteria:

    Allergy history of plasma, sodium citrate and methylene blue; 2. For patients with history of autoimmune system diseases or selective IgA deficiency, 3. the application of convalescent plasma should be evaluated cautiously by clinicians.

  4. Patients having evidence of uncontrolled cytokine release syndrome leading to end-stage multiorgan failure.

Methodology:

Total sample size is n=2000. A case report form (CRF) will have to be generated for each corona virus patient at baseline and the completion of study endpoint (at the time of discharge and at 4 weeks after experimental treatment modality using convalescent plasma.

  • A unique identification number will be issued for each patient in this protocol.
  • This data will be recorded in the national database. Data sources & Analysis: Patient data originating from patient medical record and assessments (mentioned in table below) will be recorded in the study CRF. Safety data (AEs and SAEs) from any time point during the study will be recorded in the study CRF. All analyses will be performed by third party statistician on SPSS. For continuous variables, summary statistics included n (number of observations), mean, standard deviation, median, minimum and maximum values, as well as frequencies and percentages for categorical variables will be presented.

Detailed Description

Passive immunization involves the administration of antibodies against a given agent to a susceptible individual for the purpose of preventing or treating an infectious disease due to that agent. A general principle of passive antibody therapy is that it is more effective when used for prophylaxis than for treatment of disease. When used for therapy, antibody is most effective when administered shortly after the onset of symptoms. The reason for temporal variation in efficacy is not well understood but could reflect that passive antibody works by neutralizing the initial inoculums, which is likely to be much smaller than that of established disease. As an example, passive antibody therapy for pneumococcal pneumonia was most effective when administered shortly after the onset of symptoms, and there was no benefit if antibody administration was delayed past the third day of disease.

The therapeutic benefits of convalescent plasma were formally studied in animal models in early 20th century. It efficacy was first determined in 1916, when 26 poliomyelitis patients were treated with convalescent plasma from polio survivors. Subsequently, therapeutic and prophylactic significance was explored in influenza and measles. Transfusion of immune plasma is a standard treatment modality for various viral hemorrhagic fevers. Its efficacy in treating Ebola Virus Disease is also well established. Studies have reported reduction viral load in patients with H1N1 influenza. Of special attention is the meta-analysis, carried out by Mair-Jenkinset al, concluding effectiveness of passive immunization as a treatment option for severe viral acute respiratory infections caused by SARS corona virus, influenza A (H1N1), avian influenza A (H5N1) and Spanish influenza A. Efficacy of convalescent plasma has been anecdotally reported in SARS-CoV-2 infections.
