Title: Living with
Thalassemia
For many years, people assumed that the iron overload is
seen in beta thalassemia patients is due to the frequent blood transfusion therapy
(can give rise excess amount of iron-containing hemoglobin in the body) alone.
However, recent studies have shown that patients with beta-thalassemia
intermedia who has not undergo blood transfusion therapy have
“higher-than-average” iron stores. For example the rate of iron uptake in the
gut were 3 to 4 times higher than normal.
Besides the health problem that iron overload can
cause, it can also affect the development of both male and female sex organ
which in turn can affect the reproductive capabilities of a person with
thalassemia. The article which we have choose to research on is based on the
experiences and stories of individuals that has undergo careful interview by a
panel of experts but has not been published in a medical journal.
Individuals
with thalassemia may experience delayed puberty, due to the deficiency of
hormones (testosterone and estrogen) necessary for sexual maturation cause by
iron overload. Although many eventually would enter puberty, some do not reach
sexual maturity and thus has a complication called “hypogonadism”. For females,
those who never begin menses are said to have primary amenorrhea, while those
who transiently have menses are said to have secondary amenorrhea. Delayed
puberty, hypogonadism and amenorrhea are signs of hormone deficiency and hence
may likely cause fertility problem. For
example, most affected males are not able to produce adequate amount of sperms
and affected females do not ovulate.
Hi!
ReplyDeleteFirst off, good job with the blog! It's really interesting. :)
Anyway, I understand from your post that both patients with beta thalassemia who undergoes frequent blood transfusions and those who do not were found to have higher than average iron stores. By any chance do you know if there is a difference in the level of iron between both groups? (I'm also assuming that the high amount of iron is due to autoimmunity. Correct me if I'm wrong?)
Hello!
DeleteYes, there is a difference in the level of iron storage between both groups. All affected individuals have an increase in iron level. However, those who undergoes frequent blood transfusion will have a even higher level of iron., develops iron-overload and iron-induced oxidative stress.
Yes, iron overload can also be due to autoimmunity. Autoimmunity cause destruction of Red Blood cells, therefore, the body will produce more Red Blood cells due to homeostasis.
Thank you!
