 DRDO (Defense Research and Development Organization) has developed 2-DG (2 Deoxy-D-Glucose) for Covid19 and the first batch of this Anti-Covid19 drug was released by Defense and Health Ministers of India on 17/5/2021. 2-DG has got emergency approval as an adjunct drug in moderate to severe cases of Covid19 in India.

Mechanism of Action and Role in Cancer treatment:

Glucose is metabolized through 2 pathway in human body. Aerobic (Oxidative phosphorylation) and Anaerobic (Glycolysis). 2-DG was earlier used as an adjuvant therapy in some Cancers. 2-DG blocks Glycolysis (anaerobic metabolism of Glucose). 2.DG forms a dead end in Glycolysis at the Isomerase enzyme level. Cancer cells which largely depend on Glucose for their energy, have a lot of Glucose transporters on their cells, thereby taking in large amounts of 2-DG (which mimics Glucose). Cancer cells utilize Glycolysis to metabolize Glucose- This was demonstrated by Nobel Laurette Otto Warburg. But 2-DG can not be metabolized through Glycolysis, thereby cancer cells starve and die slowly. Therefore it acts as a Glucose analogue that inhibits Glucose metabolism. Click here.

Role in Covid19:

2-DG enters all cells in the body-including the viral cells/particles. Just like in Cancer cells, 2-DG blocks Glycolysis and deprives nutrition of the virus. When used along with other standard treatment for Covid19, it has shown good improvement in moderate to severe cases in a clinical trial done in India. But experts are not sure about its efficacy no large scale studies have been done yet. But based on the early studies, government and doctors are optimistic that 2-DG can help Covid19 patients recover faster and decrease oxygen dependency in these patients. As the virus is denied nutrition and energy, it stops replicating and lungs clear faster.

Role in Cytokine Storm in Covid19 patients:

The intense and disproportionate immune reaction seen in response to Covid19 viral infection in some patients, is termed as Cytokine storm. Cytokine storm has been thought as one of the major reasons for death in Covid19 patients. Studies have shown that 2-DG along with low dose radiation can help quell Cytokine Storm. 

2-DG is an oral drug and will be available in sachets. It is to be mixed with water and taken.

FDA is infamous for 'approving' deadly drugs: Pfizer's Covid19 vaccine is one of them.

By Dr. Ahmed
FDA approved does not mean safe. The FDA in recent years has been approving some deadly medicines that kill people, only to later 'recall' them from the market. By the time the pharmaceutical company (makers of the deadly drug) make huge profits and FDA people get their cut through legalized quid pro quo. Making money out of people's health is nothing new for those sitting in high positions of the 'health industry'. Infact it has reached a sadistic proportions where these people enjoy it. Because now the Big Pharma is involved in eugenics and depopulation agenda.  Still in Clinical Trails but 'Approved'. Forget about the 'rare' drugs or drugs used in rare diseases, a common, over the counter heart burn medicine such as Ranitidine (Rantac/Zantac) was pulled off the market by the FDA because it had a carcinogenic substance called NDMA in it. It has been known to cause heart attacks, liver failure, triggering porphyria attacks and pneumonia . Imagin...

Acne

By Dr. Ahmed
Acne Vulgaris : Acne vulgaris is a self limiting disorder of teenagers and young adults.But 10-20% of adults may continue to experience this disorder. In adolescence, there is increased secretion of sebum from sebaceous glands. The glands get blocked with the retained sebum and kerotinous debris. Small cysts called Comedons are formed due to blockage of hair follicles. Proprionobacterium acnes is the cyst and caused production of fatty acids within the cysts. Thus causing infection of the cyst and bursting of the cyst wall. The extrusion of oily, keratinous debris triggers a foreign body reaction develops. Comedones : These are of two types- Closed comedones = White heads. Opened comedones = Black heads. The closed comedones are mostly associated with inflammatory lesions like papules , cysts and nodules. These are seen as small white heads with the naked eye or sometimes are not visible to the naked eye. The Open comedones are seen as Black heads. These are more st...

Pathology- Cardiac Tumors

By Dr. Ahmed
Cardiac Myxoma: It is derived from the Mesenchyme and usually arise within the left atrium near the fossa ovalis. It restrict the blood flow to left ventricle. Shows constitutional signs of fever, weight loss and anemia. Microscopic picture- Stellate shaped cells in the myxoid background. Complications- Embolism (mostly in the brain), Ball valve obstruction of valves. Cardiac Rhabdomyomas: Benign tumour arising from myocardium.. Associated with Tuberous sclerosis . Metastatic Disease: Most commonly from Lungs. This is more common than primary cardiac tumors.
