Intermedia has always been a somewhat arbitrary classification, with its definition changing, depending on who you ask. Probably the most commonly accepted definition was that if the patient doesn't transfuse regularly as a child, and has two beta gene mutations, the classification is intermedia. Because of the many different mutations and multiple possible combinations of these genes, any classification will cover a broad range of conditions.
Unfortunately, we are not yet quite to the point where we can say intermedia or major by the combination of mutations present. Right now we mainly have these few classifications of thal to work with, but in the near future, as more people have DNA tests and their genes are cataloged, we will see computer programs that will predict the type and severity of the thalassemia and also be used to design specific treatments for patients from birth. How low the Hb will drop will be predicted by the combination of genes involved, including any other modifying genes. The computer program to catalog these mutations and predict accordingly already exists. What is needed now is a major effort to catalog all the different gene variations involved in the group of blood disorders all lumped together under the name, thalassemia.
Quality of life is big concern for thals ,
as all of us know - it would be best if gene therapy gets success , but what till then?
we can work for-
reducing iron overload,
reducing amount of blood getting transfuse,
reducing Endocrine related disturbances,
reducing osteoporosis,
retardation of ageing,
reducing secondary infections,
protecting liver , spleen, heart , kidney , lungs, ears, vision, joints etc.
increasing time between two consecutive blood transfusions.
we all can gets these by simply Yoga , Ayurveda , and Naturopathy.
