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, Apr 29: Janata Dal-Secular leader and former Karnataka chief minister HD Kumaraswamy on Tuesday accused the central government of writing off loans of those who are facing charges of fraud.

In a series of tweets, Kumaraswamy slammed the central government.

"Really? At a time when the whole world is worried about unprecedented economic emergency, writing off Rs 68,000 crore loans of willful big fish defaulters became the best antidote to the economic crisis? And how is 50k cr package to mutual funds going to help the common man?" he tweeted.

In another tweet, Kumaraswamy said that "Billionaire scamsters like Vijay Mallya, Mehul Choksy, Sanjay Junjunwala seem to be very dear to this government".

"Na khaunga, na khane dunga" is yet another jumla unraveled. Billionaire scamsters like Vijay Malya, Mehul Choksy, Sanjay Junjunwala seem to be very dear to this government. The poor are dying by the roadside, farmers are desperate, the middle class is faced with economic doom.

The government has done little to help. But it writes off loans of those who are facing charges of fraud! What patriotism! What nationalism!" he tweeted.

New Delhi, Mar 30: Congress MP Rajmohan Unnithan on Monday approached the Supreme Court seeking directions to open the Karnataka-Kerala border to allow movement of ambulances and other emergency vehicles for the transport of essential items to Kerala.

Unnithan, who is an MP From Kerala's Kasaragod constituency, filed a plea seeking direction to Karnataka to open the borders with Kerala and in particular Kasargod-Mangalore border at Talappadi.

The petition sought directions to Karnataka to allow the movement of ambulances, emergency vehicles, trucks and other vehicles carrying essential and non-essential items to Kerala. It also sought to stay the blockade imposed by Karnataka with its border states.

The plea also sought directions to Karnataka to register an FIR and constitute a special investigation team (SIT) under the supervision of this court to enquire against the concerned authorities including the police officials whose action led to the death of two citizens.

It said that the imposition of such a blockade at a time when the supply of commodities is itself hit hard and when a medical emergency has plagued the entire country is a clear violation of Articles 21 and 19(d) of the Constitution.

"This blockade has also resulted in cutting off the essential lifeline of National Highways and State Highways and major District Roads leading to the State of Kerala which has resulted in the shortage of supply of essential and non-essential items to the State of Kerala leading to shortage supply of food and medical supplies," the plea said.

"This ill-planned and dangerous blockade has claimed the life of a 70-year-old woman who was denied entry into Karnataka even for the purpose of urgent medical treatment which was only available in the medical hub of Mangalore. This is a clear case of violation of the right to life with dignity by the state as citizens are made to die on the roads because of the action of the state which is in total disregard to Article 21," it added.

This comes as the country is under a 21-day lockdown to prevent the spread of coronavirus, which according to the Ministry of Health and Family Affairs has claimed the lives of 29 people and infected a total of 1071 people as on Monday morning.
