Today (June 14) is World Blood Donor Day.

Donate blood. Save lives. Get healthier.

Blood and blood products obtained by blood donation can help save the lives of millions of people. Blood is required for medical problems like-

– Anaemia
– Trauma
– Complications during pregnancy and delivery
– Surgical emergencies
– Medical conditions like Thalassaemia, Sickle cell disease, Clotting factor deficiency (Hemophilia)
– Blood cancers
– Cancer patients on chemotherapy

Blood cannot be synthetically manufactured. Blood donated by donors is the ONLY source!

Blood donation not only helps those in need but it also has certain health benefits for the blood donors.

It decreases blood viscosity (thickness of blood) and enables a better flow of blood in the body. This also prevents damage to the arteries and maintains a healthy heart and blood vessels.
It regulates iron levels in the blood. Presence of excess iron in the blood can be damaging to blood vessels due to oxidative stress.

It regulates blood regeneration. Replacement of the red cells takes 48 hours and complete replacement takes 1-2 months.
Lowers the risk of certain cancers (liver lung colon, stomach, throat).

Evaluations done before blood donation enable donors to get regular check-ups and monitor their health.

It provides a sense of fulfillment and optimism as you know you have done a good deed.

Severity of Diarrhoea is Affected by the Blood Types

Enterotoxigenic E. coli are responsible for millions of cases of diarrhoea and hundreds of thousands of deaths every year, mainly of young children.

A bacteria associated with travellers’ diarrhoea and children in underdeveloped areas of the world causes more severe disease in people with blood type A but not blood type O or B, finds a study.

Enterotoxigenic E. coli are responsible for millions of cases of diarrhoea and hundreds of thousands of deaths every year, mainly of young children.

The bacteria release a protein that latches onto intestinal cells in people with blood type A, but not blood type O or B.

A vaccine targeting that protein could potentially protect people with type A blood against the deadliest effects of enterotoxigenic E. coli (Escherichia coli) infection.

“We think this protein is responsible for this blood-group difference in disease severity,” said James Fleckenstein, Associate Professor at the Washington University in St. Louis.

“A vaccine targeting this protein would potentially protect the individuals at highest risk for severe disease.”

For the study, published in The Journal of Clinical Investigation, the team gave healthy volunteers a dose of an E. coli strain originally isolated from a person in Bangladesh with severe, cholera-like diarrhoea.

They observed the volunteers for five days and obtained data and blood samples from over 100 people and found that people with blood type A got sick sooner and more seriously than those of other blood types.

More than eight of 10 (81 per cent) blood group A people developed diarrhoea that required treatment, as compared with about half of people with blood group B or O.

The researchers also found that the bacteria produce a specific protein that sticks to A-type sugars – but not B or O-type sugars – on intestinal cells.

Since the protein also sticks to E. coli, it effectively fastens the bacteria to the intestinal wall, making it easy for them to deliver diarrhoea-causing toxins to intestinal cells.

The effect of blood group in people infected with this strain of E. coli was striking and significant, but it doesn’t mean people should change their behaviour based on blood type, the researchers said. IANS.
