Detailed Description
-----------------
The current COVID19 pandemic poses a huge challenge on health authorities and infrastructure due to rapid progression of infection with an estimated rate of severe disease that needs hospitalization and medical intervention. It is also noteworthy that health care workers are at high risk of contracting COVID19 when dealing with cases. Previous experience with Corona SARS demonstrated a therapeutic benefit of using convalescent plasma for patients with Corona SARS in Hong Kong. Passive immunization using hyper immunoglobulin preparations against measles as well as early treatment was proven effective when compared to no intervention conservative approach . A recent publication encourages the use of COVID19 convalescent serum for the preparation of hyper immunoglobulins to be used for passive immunization as well as treatment of early disease before the development of lower respiratory tract disease; pneumonia. Provision of Convalescent COVID19 hyper immunoglobulin: This can be achieved through one of the following three approaches: Fist approach: Convalescent COVID19 immunoglobulins can be obtained by transfusion of 1 - 4 units of COVID19 FFP for passive immunization or treatment of early disease. The advantages of this approach is that it is easy to prepare such units of FFP through regular blood banks. Disadvantages include variability of existence and levels of neutralizing COVID19 immunoglobulins in individual plasma units. This may result in variability of effectiveness for such an approach for prevention and treatment. Risk of transfusion transmitted infections as well as immunological adverse events due to infusion of large volume of FFP are among other disadvantages of using individual FFP units. Second approach: Classical industrial COVID19 hyper immunoglobulins from convalescent donors. This approach provides more consistent small volumes of concentrated hyperimmunoglobulin preparations due to pooling of plasma donations from large number of convalescent donors which bypasses the variability of neutralizing immunoglobulins in individual plasma donations. The preparation of hyper immunoglobulins includes steps for virus inactivation which results in safer products compared to non-virally inactivated FFP. Production of COVID19 convalescent hyper immunoglobulins under current situation is practically not feasible due to limited source COVID19 convalescent plasma, regulatory hurdles and the large volume of production batches (minimum of 100s of liters of convalescent plasma). Third approach: Recently a Swiss company developed medical device to prepare Intravenous Immunoglobulin (IVIG) preparations from only 4 liters of plasma (20 units of FFP) which is sufficient to produce 20 grams of IVIG. The technology involves the concentration of immunoglobulins from 20 plasma donations into IVIG preparations as well as virus inactivation of lipid enveloped viruses (HBV, HCV, HIV & Corona VS2) . Safety of Mini-Pool IVIG was proven in a previous clinical trial conducted in ITP pediatric population. The yield of one batch of this Mini-Pool IVIG is about 20 gms which can be sufficient for prophylaxis and/or treatment of 6 - 10 individuals.

Selected population can be both male and female with age range 21 - 50 years b. 20 high risk persons (HCPs) who are nasopharyngeal swab SARS-CoV-2 PCR negative and seronegative for SARS-CoV-2 IgM/IgG antibodies as control group. Selected population can be both male and female with age range 21 - 50 years Patient group (group B): a. 30 patients with COVID19 disease and nasopharyngeal swab or sputum SARSCoV-2 positive PCR to receive anti-SARS-CoV-2 in addition to applied clinical management protocol. Selected test group can be male or female with age >20 years b. 30 patients with COVID-19 disease and nasopharyngeal swab or sputum SARS-CoV-2 PCR positive managed according to applied clinical management protocols of COVID-19 disease as control group. Selected test group can be male or female with age >30 years Exclusion Criteria: Passive immunization group (Group A): Age less than 21 or above 50 years . Nasopharyngeal swab SARS-CoV-2 positive PCR . Presence of anti-SARS-CoV-2 IgM, IgG Presence of comorbidities such as hypertension, diabetes, chronic renal disease, previous thrombotic events or states of allergy such as urticaria or bronchial asthma as well as previous adverse events due to infusion of IVIG Patient group (group B): Age less than 20 years . SARS-CoV-2 PCR negative . COVID-19 patients who may suffer from co morbidities such as hypertension, diabetes, chronic renal disease, thrombotic tendency or history of adverse events to IVIG as well as old age will be excluded to reduce the possibility of development of serious adverse events related to infusion of IVIG unless it will be for compassionate use in advanced stages of COVID-19 patients and after obtaining informed consent
