New Delhi: Women who have conceived or have given birth to a child cannot donate their plasma because they may have developed a certain type of antibody during pregnancy and in some cases, they may have acquired plasma recipients. Can be harmful, Doctors have given this information?
Delhi’s Chief Minister Arvind Kejriwal inaugurated India’s first plasma bank at the Institute of Liver and Biliary Sciences on Thursday.
Currently, strict guidelines have been issued regarding who can donate their plasma and who does not. According to the guidelines issued in relation to eligible donors, those aged 18–60 who have fully recovered from coronavirus infection and who have no symptoms of infection for 14 days can donate plasma.
People whose weight is less than 50 kg, women who have conceived, people suffering from cancer and people suffering from kidney, heart, lung or liver disease cannot donate plasma.
Asked why pregnant women could not donate plasma, a senior ILBS physician said that women may have human leukocyte antigens when they come into contact with the baby’s blood during pregnancy and giving birth. (HLA) antibodies have been formed, which are directed against antigens on white blood cells (surfaces). The doctor said, ‘This happens because the fetus also has genetic components of the father, then mother’s disease against this foreign element. The immune system produces antibodies.
According to experts, the presence of HLA antibodies in the blood of a healthy person does not cause any health problems, but in rare cases when plasma with HLA antibodies is plated, it can cause TRALI reaction in that person.
Experts say that TRALI (lung injury associated with transfusion) is a complication that can cause problems like severe breathing, fever and low blood pressure.
