Hilltribe Blood Not Incompatible Says Maharaj Hospital Director After Misunderstanding

by CityNews

 

 

CityNews – The director of Maharaj Hospital has issued a statement denying any fact in the claims that donated blood from hill tribe people cannot be used for people in the lowlands. He confirmed that the hospital welcomes all blood donors, especially during this time as the hospital is suffering a blood shortage.

 

A press conference was held on June 27 following controversial claims that the hospital was not accepting blood donations from hill tribe people as it cannot be used with the main population.

Pure nonsense.

Hill tribe blood could be used for "lowlanders" if  meets the requirements.

It would of course have to tested as would any blood to show it is disease free.

The same requirements would be true of English blood. or any other westerners blood.

That is why you have to check the donors carefully wherever they come from.

In Malaria areas you have to be especially careful not to  use blood f from  Malaria suffers unless it was found to be free of malaria.

Absolutely....it's stupid and ridiculous to claim quality of blood based on ethnical, social or racial issues...really, human nature and it's stupidity gets overwhelming...

 

Nevertheless, the hygiene of the blood quality, it's testing and screening by laboratories, must be close to antisceptic!!...

There is some truth in this matter. Whilst the subtle differences in blood types between various ethnic groups is largely unimportant in some instances importance looms large.  For example it is important for suffers of Sickle Cell Anemia to receive blood donated from within their own ethnic group. Sadly for the Sickle Cell sufferers members of their ethnic group are reluctant donors.

You have this wrong.  Blood transfusions for sickle cell patients simply need to be phenotypically matched (checked for compatibility with O A AB and other antigen systems) and this does not require ethnic group matching!

 

See here:

 

"Standard bank blood is appropriate for the patient with sickle cell disease. The "age" of the blood (time since collection) is usually not important as long as it is within limits set by the transfusion service. Exchange transfusion with blood less than 5 days old (less than 3 days old in the small infant) helps in acute situations requiring immediate correction of the oxygen-carrying capacity. All blood should be screened for the presence of sickle hemoglobin and confirmed to be negative. A solubility test is adequate for screening in this situation. This procedure eliminates blood with sickle cell trait, which will confuse later measurements of the proportion of sickle cells or hemoglobin S. The antigenic phenotype of the red cells (at least ABO, Rh, Kell, Duffy, Kidd, Lewis, Lutheran, P, and MNS groups) should be determined in all patients older than 6 months of age."

Thanks for attempting to pass on your clear lack of knowledge about this problem. I guess you believe securing a good phenotype match is a  simple matter if so you could not be more wrong.

 

 

You forgot to copy/past this very important information.

 

"The high prevalence of alloimmunization in patients with sickle cell disease likely has several causes. Lack of phenotypic compatibility between the donor and recipient doubtless is a major factor   Do try, partington, to understand the significance of this---- It means haematologist's experience great difficulty in securing a good match --- the result of using (of necessity) poorly matched, non ethnic, blood in the past. Some phenotype's are only found within certain ethnic groups but you would likely deny this to be true.

 

My colleagues in the UK blood transfusion service are obviously, according to you, wasting their time in attempting  to expand their ethnic minority donor base. 

 

"More blood donors from Black, Asian and minority ethnic communities are needed to help patients like ******  and to meet the needs of hospitals and patients. 

Certain conditions, such as sickle cell and thalassaemia, are more prevalent within these communities. And, some rare types are also only found within these communities. Patients who require regular blood transfusions benefit from receiving blood from donors with a similar ethnic background." * 

 

*Extract from the NHS B&T Service's attempt to increase the pool of ethnic minority donors.

 

Trying to be clever by using Mr. Google as a cover for a lack of knowledge is very  unwise Mr P .........

Yo have confused two separate things.

 

The fact that some phenotypes are more common than others in certain ethnic groups does not mean blood needs to be matched by ethnic group,  it simply means that  a rare phenotype that you need is more likely to be found in this population.

 

 This is not the same thing at all.

 

As an example: "2% of the regular blood donors in England have the Ro subtype.

The Ro subtype is more than 10 times as common in individuals from Black African or Black Caribbean ethnic backgrounds, than in individuals from White ethnic backgrounds,"  [https://www.blood.co.uk/why-give-blood/the-need-for-blood/] so if you need Ro blood you are more likely to find it in your blood bank if there are a lot of Black African donors.

 

 

This does NOT mean what you actually said:

"it is important for suffers of Sickle Cell Anemia to receive blood donated from within their own ethnic group"

 

They do NOT need to receive blood donated from within their own ethnic group: if they have a very rare phenotype, e.g Ro, it is simply more likely to be found in their own ethnic group. The same phenotype donated from ANY ethnic group including Caucasians would be fine for the transfusion.

 

Alloimmunity only happens if the transfused blood has not been matched for all relevant antigens, and it is  important that this is done, as quoted in my first post.

"The antigenic phenotype of the red cells (at least ABO, Rh, Kell, Duffy, Kidd, Lewis, Lutheran, P, and MNS groups) should be determined in all patients older than 6 months of age."

Please!  

 

I have confused nothing and neither did I say that blood MUST come from matching ethnic groups. You need to learn that certain phenotypes are principally ( and practically) only found in certain groups.

If you read and understand it you will be nearer to understanding why it is important to encourage ethnic minority donation which in turn enables the creation of rare donor  groups.  

 

I have a colleague who has spent over 40 years practicing immunohaematology/transfusion medicine and she set up one of the first rare donor panels comprising mostly ethnic minority people.

OK, I understand now that when you said "it is important for suffers of Sickle Cell Anemia to receive blood donated from within their own ethnic group"

 

that you didn't actually mean all the time, or exclusively, or all sufferers, but only some selected sufferers, and only sometimes , if they are people who have a very rare blood  antigen phenotype only  ever found in that ethnic group alone.

 

I accept that if there is a rare blood antigen phenotype that is only ever found in a single ethnic group then the only way to get a complete match would be from a donor  from the same ethnic group-so let's leave it at that!

It took some time but you finally got there !

 

You got fixated by a comment of mine which was intended for general consumption and which also carried  a 'UK' caveat. In the UK these phenotype difficulties are very much related to a limited number of ethnic minorities.

Whatever the origin of the mistake, Dr Wichai did the right thing by 1) clarifying the matter, and 2) accepting responsibility for the miscommunication.
