Fisherman feared dead; search operation called off

Chithradurga, Mar 25: COVID-19-positive cases in Karnataka jumped to 42 from 33 on Tuesday, with nine cases added to the list overnight. The daughter of G M Siddeshwara, Davanagere MP, is the latest case.

Sources from the Siddeshwara family said that the MP’s daughter, along with her two children, who started from Guyana, first landed at New York airport and from there, she took a flight to New Delhi.

From Delhi, she flew to Bengaluru. And then, she and her children travelled with her father in a chaffeur-driven car on March 21 to their house in Bheemasamudra.


Siddeshwara said that protocol for COVID-19 had been followed and all who returned were under self-quarantine at his house. However, the administration was not informed of her travel history till the samples were given for test, Chitradurga Deputy Commissioner Vinoth Priya R told TNIE. The DC said the test results of the MP’s daughter were collected by district health authorities and sent to Shivamogga Institute of Medical Sciences on March 22.

The test turned out to be positive for COVID-19 and she was shifted to the isolation ward at Chigateri district hospital in Davanagere. This is the first positive case in Chitradurga.The patient, who is the wife of an Indian Diplomat in Guyana, complained of flu-like symptoms and remained self-quarantined at her house at Bheemasamudra. Her condition was informed to the health department, which collected her samples and forwarded it to the SIMS for tests, results of which arrived on Tuesday evening.

The DC said that samples of family members including the two children, and those working at the MP’s house would be collected and sent for testing to ensure proper protocol is followed. The administration has declared a ‘red zone of a 5km radius around Siddeshwara’s house at Bheemasamudra. DHO Dr Palaksha said that the patient is not suffering any serious problems and is normal. However, we have put her in the isolation ward of Chigateri District Hospital in Davangere, he said.

Bengaluru, Jun 22: Areas having three to four COVID-19 cases being termed as clusters will be totally sealed and maximum testing will be conducted there, moreover only critical cases will be shifted to COVID hospitals in Bengaluru, said Karnataka Home Minister Basavaraj Bommai.

Speaking to media persons, Karnataka Home Minister Basavaraj Bommai said, "It has been decided that clusters (areas having 3-4 #COVID19 cases) will be totally sealed and maximum testing will be done there. Only critical cases will be shifted to Covid hospitals. I demanded that police personnel are tested on priority."

"A lot of issues were discussed about the spike in COVID-19 cases. As far as hospitals are concerned there are two types of patients, asymptomatic and symptomatic, moderate and critical. Moderate and normal cases can be shifted to COVID centres," he added.

Bommai further added that beds in hospitals need to be reserved for corona warriors as well.

"There has to be a coordination between BBPM who brings the patient and the hospital, the moment a positive case is reported to avoid the waiting period. Even in hospitals, some beds have to be reserved for corona warriors. Community transmission is not yet there but we have to be prepared," he added.

Earlier today, Karnataka Chief Minister BS Yediyurappa had called an emergency meeting of concerned officials and departments to discuss measures to control rising COVID19 cases in Bengaluru.

As the numbers of COVID-19 cases are increasing in Bengaluru at an alarming rate, the Chief Minister opined that this can be contained only if preventive measures were implemented strictly.

He directed the officials to implement lockdown strictly in the clusters, which reported more number of cases, especially KR Market and surrounding areas such as Siddapura, VV Puram, Kalasipalya. It was decided to seal the adjoining streets, where the cases are reported.

He said that stringent action would be taken against those who violate quarantine and FIR would be filed if necessary.

Officers were directed to fix rates for treatment of COVID patients in private hospitals to make coronavirus treatment accessible to all.

Yediyurappa further instructed officials to set up fever clinics in all wards and maintain hygiene and provide other basic amenities to the people who were quarantined in social welfare hostels and other government institutions.

"COVID-19 should be contained without affecting the economic activities in Bengaluru, which resumed recently," he said.

"COVID War Room shall have real-time information on the availability of beds in various COVID hospitals and shall facilitate the infected person to avail treatment without losing any time," added Yediyurappa.

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.
