Blood Donor of Bombay Blood Group Saves Pregnant Woman

Aditya Hegde, a recipient of the rare Bombay blood group traveled to Chennai just to save a pregnant woman.

The 34-year-old quickly booked himself a ticket to Chennai. He went to the Government Hospital for Women and Children in Egmore, where the woman was admitted and donated a unit of blood for the woman. Since 2000, he has donated blood 55 times and not just in Bengaluru – his recipients have hailed from Delhi, Hubli, Shivamogga, Pakistan, Malaysia and Sri Lanka.

Bombay Blood Group
Bombay blood group is a rare blood type in which the people have an H antigen deficiency. They can receive or donate blood only with other individuals with the same blood group.

‘Aditya was born with a very rare blood type – HH negative, also known as the Bombay phenotype – which is found in one in 10,000 people in India and in one in a million people in Europe.’

“Most of the time, I do not even get to know who is the recipient of the blood I donate, especially if it’s in another city. Usually, the blood is taken here in Bengaluru itself. It has a shelf life of 35 days and is couriered in an ice box to the particular hospital and recipient,” Aditya explains.

He has donated blood to tumor patients, cancer patients, and pregnant women. He is in touch with Sankalp India Foundation, an NGO which connects those in need of blood to donors.

The Chennai woman, it appears, had been told after her first delivery two years ago that she may require a blood transfusion the second time around. The hospital had advised her to come a fortnight prior to her delivery date so they could withdraw her blood and preserve it in case she needed it later. But the woman did not do so, which created the emergency requirement.

Blood Groups
The blood group of a person is determined by the presence or absence of certain inherited antigenic substances and certain acquired antibodies in blood.

“The woman was able to deliver a healthy baby girl and is out of danger. Srijit Narayanan told me,” Aditya smiles happily. Srijit, a Times of India employee, had reached out to Aditya about the emergency blood requirement.

As happy as Aditya is that he was able to save her life, sometimes, he feels scared too. “This is such a rare blood group. I wonder what would happen if I am in a situation where I need blood,” he confesses.

Blood Group Diet
What is right diet for you may be the wrong one for another. The diet that suits you will depend on your blood type. This diet is called the blood group diet.

But he laughs it off quickly. “When I started donating blood 17 years ago, I didn’t know I had the Bombay blood group. It was only in 2004 that I discovered that it was HH negative. I never saw donating blood as a duty because of my blood type. It was just something I wanted to do and intend to continue doing as long as I can.”

Heart Attack Risk Found to be Higher Among Non-O Blood Groups
People with non-O blood groups are at a higher risk of heart attack and cardiovascular mortality, reveals study.

First discovered in Bombay (now Mumbai) in 1952, this is an extremely rare blood group. Red blood cells (RBCs), white blood cells and the plasma come together to form blood groups.

On their surface, RBCs carry markers, with which the plasma interacts. While RBCs have antigens, the plasma has antibodies.

The antigens can be A or B or both. If the RBCs have antigen A, the plasma will be the B antibody or the other way round. These determine if the blood type will be A, B or AB. If the RBCs have neither antigen A nor B, the plasma has antibodies of both, and the blood type then is O.

There is another variable called the Rh factor which determines the ‘positive’ or ‘negative’ marker in the blood type. If the RBCs have Rh factor on their surface, the blood type would be positive. If the Rh factor is absent, the blood type would be negative.

It is the interaction between the RBCs and the plasma which sets apart a blood type and is important for a robust immune system.

There’s a master antigen H, which is present in all blood groups. This antigen is needed to generate A, B, AB and O antigens. But when the antigen H is absent from the cell and only its antibody is present in the plasma, it leads to the occurrence of the rare HH blood group.

The HH blood type is a result of extensive inbreeding in close-community marriages which limit the gene pool. It is, therefore, possible that people with the Bombay blood group have common ancestral roots.
