The lymphoproliferative disorders (LD) are a heterogeneous group of at least 70 conditions that result from the clonal proliferation of B, T and NK cells. IBD-associated lymphomas are typically B-cell LD, while T-cell or Hodgkin's lymphomas are rare. In IBD patients not on immunosuppression, the risk of LD seems to be similar or slightly higher than the background population risk. Thiopurine therapy is associated with an increased risk: the relative risk is increased 4-6 fold and the absolute risk varies between 1 in 4,000-5,000 for those aged 20-29 to 1 in 300-400 in those over 70. It is difficult to quantify the risk of anti-TNF therapy alone, however it appears to be less than for thiopurines alone. There is particular concern regarding: the development of post-transplant-like LD in those with latent EBV infection exposed to immunosuppressives; the occurrence of hepatosplenic T cell lymphoma in patients treated with combination anti-TNF and thiopurine therapy; and the development of hemophagocytic lymphohistiocytosis in those who acquire a primary EBV or other infection whilst on immunosuppressive medication. There are currently no guidelines for monitoring EBV (or other virus) status in patients on immunosuppression, although it could be used to monitor those who have a prior history of lymphoma and are about to start a thiopurine or anti-TNF agent. In discussing the risks of lymphoproliferative disorders associated with agents used for the treatment of IBD, patients can often be reassured that the benefits of such therapy still outweigh the small, but real, risks.
Am old enough to understand the difference between the Bay of Pigs - and roasting a pig at a epicurian feast. Been thru the hippy, yippie and yuppie years - always remaining who I am.
Very much believe in "Sing your own song - weave your own tapestry"
Am young enough to still know the thrill of new discoveries, the beauty of the evening, to celebrate the joy of another tommorow.
Survived these many decades with a severe medical problems. Sorting out the maze of now having two lymphomas and all their nasty little companions, but I continue.
Besides, being a simple iconoclastic eclectic, have been called many things. An incurable romanticist - with a strong touch of reality. Thinker, intellectual (God, how I hate that term) - been told I am a lion with the heart of the poet.
Know how to wage war and conquer my foes - but would rather be known as one who brings hope and life. To bring hope into anothers life is the ultimate of joys.
Life should be about bringing hope, peace, vision... a sense of purpose beyond yourself.
