Contributing Causes
Cases have been reported of PML being caused by pharmacological agents, although this could be due in part to the existing impaired immune response or 'drug combination therapies' rather than individual drugs. These include efalizumab, belatacept, rituximab, natalizumab, infliximab chemotherapy, corticosteroids, and various transplant drugs such as tacrolimus.

Famous quotes containing the word contributing:
“But then in what way are things called good? They do not seem to be like the things that only chance to have the same name. Are goods one then by being derived from one good or by all contributing to one good, or are they rather one by analogy? Certainly as sight is in the body, so is reason in the soul, and so on in other cases.”
—Aristotle (384–322 B.C.)
“[Girls] study under the paralyzing idea that their acquirements cannot be brought into practical use. They may subserve the purposes of promoting individual domestic pleasure and social enjoyment in conversation, but what are they in comparison with the grand stimulation of independence and self- reliance, of the capability of contributing to the comfort and happiness of those whom they love as their own souls?”
—Sarah M. Grimke (1792–1873)
