Should we hang Modi now, asks K'taka Cong leader

Udupi, June 2: The number of positive cases may continue to be more in Udupi district since the results of more than 3,000 samples are pending with Labs.

The district total cases to 260. The figure had seemed far-fetched on May 15, when the number of cases stood at just three. The latest spike has been attributed to the return of migrants from other States as well as from abroad. These samples are from people who returned to the district in the last two weeks.

This delay is because the laboratories testing samples from Udupi are burdened with a high case-load after more than 8,500 people returned to the district, particularly from the neighbouring state of Maharashtra.

"Samples have piled up after the influx of people returning from other states and from abroad," says Dr Prashant Bhat, nodal officer for COVID-19 in Udupi. This delay has caused returnees in institutional quarantine to stay on for as long as 18 days.

The designated laboratory for coronavirus testing in Udupi is Wenlock District Hospital in Mangaluru. The district administration also sends samples to laboratories at the Kasturba Hospital in Manipal, Yenepoya Medical College, Mangaluru, KS Hegde Medical Academy, Mangaluru, and Viral Diagnostic Laboratory in Shivamogga. Apart from Udupi, the laboratory in Manipal is also testing samples from Uttara Kannada district. The laboratory in Shivamogga is also testing samples from Shivamogga and Bijapur districts. The laboratories in Mangaluru, similarly, have samples from Dakshina Kannada district.

Dr Avinash Shetty, Medical Superintendent of Kasturba Hospital in Manipal, one of the private laboratories being used by the Udupi district administration, said that they are testing samples in batches. "We received around 600 samples today and we will be testing them now. The backlog of samples should be cleared in the next few days," Dr Avinash said.

All 73 cases reported in Udupi on Monday were patients with travel history of returning from Maharashtra or patients with travel history of returning from abroad.

In cases of some patients who tested coronavirus positive in the past week, people were released from institutional quarantine after a stipulated period only to be tracked down again and admitted in hospitals after their results returned positive.

While two such cases emerged in Belapu and Belman in the district, the administration is now following up with others who were released from institutional quarantine to ensure they remain in home quarantine till their test results are confirmed.

The spike in cases among returning migrants in Udupi also comes at a time the Karnataka government reduced restrictions on interstate travel.

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.
