Stimulating immune responses in early stages may hold key to effective treatment of COVID-19

Bengaluru, Mar 28: Sun Tsu, in 'The Art of War' speaks of a skilful general who can subdue his enemy without any fighting. This constitutes the ultimate triumph which is referred to as stratagem. Today, we would need one such when we are faced with the '21-day corona challenge' for India.
Nearly four weeks back, Dr Jyothsna Rao, Dr Gururaj Rao and I sat across the OPD in the afternoon at HCG Bengaluru discussing our ongoing cancer immunology research. While on this topic, we drifted into the discussion on the coronavirus. During this engaging discussion, we wondered the similarity of the enigma between the virus and cancer. I paused to ask Dr Jyothsna and Dr Guru - how we wish we could do something against this virus.
Dr Jyothsna is a PhD from NCBS and had worked under Dr Ralph Steinman, physician and researcher from Rockefeller University, who won the Nobel Prize for his discovery of the dendritic cell and its role in adaptive immunity in 2011. Dr Gururaj is a molecular and cell biologist who did his PhD at the Chapel Hill, University of North Carolina and is the Director of iCrest.
Jyothsna while hearing our perplexing conversation on the covid intervened, "Yes, surely. I think we should take a break from cancer and focus on the innate and adaptive immunity role in COVID-19."
Thus began this sincere attempt to relook the human immune system from the eyes of the COVID-19.
We have 10 types of immune cells at the least which are widely dispersed in millions across the body. When our body is invaded by a foreign organism (bacteria, fungi or virus), these cells work with each other to destroy the invader.
Now, the question is - how do the immune cells talk to each other? They use small-molecule substances called cytokines (cyto means cells; kine means movement). There are many cytokines that are involved in work on the immune system. The most relevant for viruses are interferons.
Interferons (IFN) as the name reflects have an ability to interfere with the viral activity and stop their multiplication. These specialised signal proteins are released by our cells in response to a viral attack to forewarn other cells. They help build the antiviral proteins within the cells to kill the virus as it tries to invade the new cells.
Historically, interferons are a group of cytokines known to be potent antiviral agents against viruses and a hallmark cytokine induced by the host upon viral infections. Interferons possess unique immunoregulatory activities and are signature cytokines released by (TH1) T immune cells, which are crucial in viral infections.
As the outbreak of COVID-19 grapples us, an urgent need for finding strategies to combat the virus is growing. Coronaviruses (CoVs) are a group of RNA viruses. In patients infected with coronavirus, it was indicated that the activation of the IFN does not occur until 48 hours post-infection. Thus the delayed IFN-related antiviral response by the healthy cells leads to coronavirus evade the immune response.
Numerous studies have presented the success in defeating CoVs by the direct administration of IFNs. In a combination as a concoction, it was shown to synergistically inhibit the virus replication in vitro.
Moreover, it is understood that the earlier induction of IFNs in children although they have a less developed immune system could be the reason behind the children being least affected.
The key to success in reducing the disease fatality might be the stimulation of the immune responses to trigger IFN production at the very early stages of the disease, which might be done through the administration of IFN. Despite the evidence for the efficacy of IFNs in treating CoV-induced infections, the proper dosing and ideal timing for such interventions needs to be verified in clinical trials.
For the later stages of the diseases in advance stages where patients are on ventilator and have developed respiratory distress, we propose to utilise the mesenchymal cells derived from donor bone marrow that have been known to treat acute respiratory syndrome. Mesenchymal cells are known to possess anti-inflammatory activity and thus used often in autoimmune diseases.
With this scientific background, we have activated T cells from healthy donors, in a cGMP facility at iCrest - HCG hospital with an enriched cocktail of cytokines rich in Interferons. Injections of this cocktail we believe will result in a surge of cytokines in the body of the infected person and will boost his ability to fight the virus in the early phases. We are in the initial phases of this study and hope to be ready in the coming weeks with meaningful data on its potential utility.
Currently, it awaits government approvals (Union and state) and we have applied to central drugs authority for their initial evaluation and further directions.
As my Guru often expounded the philosophy of 'Seva' - the goal of education is knowledge, the end goal of knowledge is service. In this attempt to serve our fellow humans at this brink of unprecedented crisis, medical fraternity stands with you and promises to do our best for your safety.
We assure to exhaust every bit of our spirit in this fight against coronavirus. We have lost the sight of shores and travelled thus far, but that is the mandatory first step to cross the ocean. Are we going to succeed in this battle, is something only time will answer.

Bengaluru, Jun 28: Former Chief Minister and senior Congress leader Siddaramaiah asked the Karnataka government to release White Paper over the state of healthcare system and the government's preparedness to address COVID-19 pandemic.

He said that the State Government to come clean on the charges of misappropriation of large sums of funds in the name of fighting the COVID-19 pandemic in the state.

"People are extremely worried about the state of our healthcare system and the government's preparedness to address pandemic. It is the responsibility of Karnataka Chief Minister to clear the doubts and reduce the panic among people. I urge the government to #ReleaseWhitePaper about the same," the Congress leader tweeted.

Siddaramaiah said that the Chief Minister should let people know about the amount of money already spent to improve healthcare facilities, the number of beds and ventilators increased and about the supply of PPE kits to COVID-19 warriors.

"Karnataka Chief Minister should also reveal the contribution of PMO India to our state. Has Karnataka Chief Minister BS Yediyurappa demanded anything from Narendra Modi? How much of PM CARES Fund is spent for Karnataka's healthcare?" he asked in another tweet.

He went on to say that PMO India and Chief Minister of Karnataka "wasted crucial time during lockdown."

"The purpose of lockdown was to fill the gaps in health care system. But they just widened it by frequently changing the protocols and by not doing adequate tests," he said.

"Karnataka Chief Minister and other departments have failed to answer my multiple queries regarding the actions taken. As a leader of opposition, it is my right to question the government on behalf of people. Deliberate act of denying information is a breach of privilege. Government hospitals have reached its capacity and private hospitals are not ready to treat patients at capped prices," he wrote.

Siddaramaiah said that the Karnataka Chief Minister should either convince private players or take action against them, and added, "Not doing both is like pushing people off the cliff."

He tweeted, "The testing rates per day have come down in last 15 days even when the cases are rising. What is stopping the government from increasing the testing? The government is putting people at risk by not testing adequately."

Further attacking the state government, he wrote, "Our state needs 9000 ventilators, but we have only 1500, PMO India has sent 90 to us. Is this a joke to Karnataka Chief Minister and PMO India? #ReleaseWhitePaper about the ways that they plan to increase ventilators."

Bengaluru, May 27: Congress leader Siddaramaiah on Wednesday hit out at Chief Minister BS Yediyurappa-led Karnataka government for allegedly "betraying" the people by not fulfilling its Rs 1,610 crore COVID-19 package promise.

Taking a dig at Yediyurappa over the matter, the Congress leader tweeted, "Chief Minister of Karnataka BS Yediyurappa has betrayed people by not fulfilling his Rs 1,610 crore package promise. He seems to be following his @BJP4India leader @PMOIndia @narendramodi."

"Crisis and vulnerability should not be misused for political gains and BJP for India is insensitive towards the same," the former Karnataka Chief Minister said.

On May 6, Yediyurappa had urged migrant workers to stay back as construction activities have resumed and announced a Rs 1,610 crores COVID-19 financial package for the state.

"A package of Rs 1,610 crores will be released as COVID-19 financial relief. One time compensation of Rs 5,000 will be given to 2,30,000 barbers and 7,75,000 drivers," the Chief Minister said.

Referring to media reports, Siddarmiah cornered the state government for asking the licence to release funds for unorganised sector workers.

"How can we expect washermen and other unorganised sector workers to have licence for their work?" he asked.

It looks like Karnataka Chief Minister is very far from reality, he added.

The minister announced that Karnataka Secondary Education Examination Board (KSEEB) will conduct SSLC examination between June 25 to July 4 and the PUC exam for English paper will be held on June, 18, 2020.

"Examinations for Secondary School Leaving Certificate (SSLC) will be conducted between June 25 and July 4 in Karnataka. Exams for English paper of Pre-University Course (PUC) will he held on June 18: Karnataka Education Minister S Suresh Kumar," ANI tweeted.

The minister for primary and secondary education had held a meeting with the department officials to discuss the feasibility of conducting the exam.

Modalities of conducting the examination in the current situation of the COVID 19 pandemic while taking care of interests of students is of paramount importance, S Suresh Kumar said adding these issues have been kept in mind while finalising the schedule.

With inter-state and inter-district mobility a major issue with public transport not available and also due to 14-day institutional quarantine norms, the minister had told TOI that an idea has been introduced to allow students appear for the examination in the district where they presently are than at their designated examination centre.
