Outcome of COVID-19 Cases Based on Tuberculin Test: Can Previous BCG Alter the Prognosis?

There isn’t any proof that the Bacille Calmette-Guérin vaccine (BCG) protects folks towards an infection with COVID-19 virus. Two medical trials addressing this query are underway, and WHO will consider the proof when it’s obtainable. In the absence of proof, WHO doesn’t advocate BCG vaccination for the prevention of COVID-19. WHO continues to advocate neonatal BCG vaccination in nations or settings with a excessive incidence of tuberculosis.

Outcome of COVID-19 Cases Based on Tuberculin Test: Can Previous BCG Alter the Prognosis?

There is experimental proof from each animal and human research that the BCG vaccine has non-specific results on the immune system. These results haven’t been nicely characterised and their medical relevance is unknown.

Since December of 2019 COVID-19 is a quickly spreading virus presently infecting over 1,000,000 people worldwide, over 250,000, and over 6,000 deaths in the United States as of 03/31/2020.1

Presently there are not any FDA accepted remedies or immunizations towards COVID-19; nonetheless, the FDA has granted an EUA for the therapy of hospitalized sufferers with hydroxycholorquine.2

Depending on case sequence the anticipated case fatality fee for COVID-19 with out therapy is between 0.5-10% with the most definitely vary between 1-3% which is>>10x the anticipated case fatality fee of seasonal influenza.

Several research have reported anecdotal and promising preliminary knowledge on the therapy of Coronavirus. Based on the restricted proof from these research, pre-exposure prophylaxis, or post-exposure prophylaxis could also be useful.3-21

Due to the nature of the work in the Pentagon a number of important people are unable to apply efficient social distancing measures with a view to guarantee their mission important jobs for continuity of authorities and nationwide protection.

Any treatment, therapy protocol, or epidemiological management measure which seems protected preliminarily and could be carried out have to be examined and put into apply instantly with a view to defend senior leaders and different mission important personnel.

The main purpose of this research is to find out whether or not pre-exposure prophylaxis decreases the incidence of COVID-19 infections amongst personnel, and the secondary purpose is to find out whether or not post-exposure prophylaxis decreases the severity of sickness and speeds the return to work of personnel.

The Pentagon Medical Facilities consist of 2 separate medical clinics and a pair of separate dental clinics that collaborate on each day actions. Operational personnel with particular medical necessities similar to aviators and Personnel Reliability Program (PRP) personnel are sometimes seen in the Pentagon Flight Medicine Clinic whereas different personnel are seen in the DiLorenzo Tricare Health Clinic Pentagon.

Based on the EUAs for hydroxychloroquine & chloroquine, that are in important nationwide scarcity, and inpatient therapy protocols, hydroxychloroquine and chloroquine present potential for therapy of sufferers hospitalized for COVID-19. We suspect that therapy of early or asymptomatic uncovered sufferers with chloroquine could lower an infection charges or restrict an infection severity if pre-treated or handled early

Informed and appropriately witnessed consent* as required might be obtained by the PI or every other AI added in subsequent modifications to the protocol. Due to telemedicine and social distancing with the ongoing disaster this might be by distance mechanisms together with digital versus moist signature as clinically indicated based mostly on the state of affairs to attenuate affected person and supplier dangers.

Patients might be assigned sequential affected person identifier numbers throughout their consent course of for monitoring functions.

Initial procedures for security monitoring together with CBC, CMP, UA, G6PD testing (if prior information unavailable), and EKG (if prior information unavailable) might be obtained after consent.

Medication retrieval:

The affected person will then current to the DTHC pharmacy with their envelope and duplicate of their enrollment consent to retrieve their medicines. The pharmacist will open their envelope and hand them treatment 1, 2, or Three as acceptable, and document their research quantity and group quantity on a working spreadsheet maintained with out PII in the pharmacy.

Patients will present their research quantity to the pharmacy for any refills throughout the period of the research.

If a person is on pre-exposure prophylaxis and develops COVID-19 they are going to proceed on therapy by means of the post-exposure prophylaxis window of 7 days on the dose they have been assigned at randomization.

Records assortment:

Patient information might be queried in 5 methods: 1. At research enrollment 2. During consent affected person’s might be requested to tell research personnel in the event that they develop into sick or uncovered to COVID-19; sufferers will current with issues 3. Monthly information critiques might be carried out to find out if sufferers have develop into optimistic or are displaying indicators of COVID-19 4. When the research personnel are knowledgeable by public well being officers of a optimistic COVID-19 affected person assigned to the Pentagon 5. When the declared public well being emergency is over or the research ends (at its 1 yr anniversary if the public well being emergency has not ended).

Results might be retrieved from AHTLA, CHCS, request to treating civilian suppliers for care exterior the MHS, Essentris, and MHS imaging techniques similar to Impax.

Records assortment will embody as acceptable:

1. Date of publicity – to find out optimum timing of post-exposure prophylaxis throughout knowledge evaluation.

2. Date of optimistic check – to find out optimum timing of post-exposure prophylaxis on knowledge evaluation.

3. Medical comorbidities as they’re identified or develop into identified together with HTN, DM, Male Gender, Age, Pulmonary Disease, Health Care Worker / First Responder, and/or identified cardiac illness. – to manage and check for cofounding circumstances in addition to danger stratify
