Graft thrombosis is the most common non-immunological cause of early graft failure.
A simplified nomenclature for primary vasculitic conditions, each one defined by their most common clinical, histological and immunological characteristics, was proposed by an ad hoc expert committee in 1994 [ 1].
To date, the induction of an EBV antigen-specific T-cell response (primarily CD8+ T cells) in patients with vaccines and adoptive T-cell therapy are the two most common strategies for the immunological treatment of EBV-associated cancers.
A normal result excluded X-linked lymphoproliferative disease, the most common inborn cause of abnormal immunological reaction to EBV infection.
An interesting feature of T-LGL leukemia is its strong association with a number of autoimmune disorders and immunological abnormalities, most common in patients with rheumatoid arthritis (RA) (30% of patients), which usually precedes or develops concurrently with the hematological process [ 8- 10].
This treatment effect remained when the SRI was modified not to include SELENA SLEDAI score contributions from any one of the three most common organ domains (mucocutaneous, musculoskeletal and immunological), and from both the mucocutaneous and musculoskeletal organ domains (data not shown).
Similarly neutropenia is still the most common pre-disposing factor, it is often superimposed on other immunological deficits (e.g. impaired cellular or humoral immunity) each of which is associated with a specific spectrum of infection.
Osteoarthritis (OA) is the most common arthritic condition and, like rheumatoid arthritis (RA), presents an inflammatory environment with immunological involvement and this has been an enduring obstacle that can potentially limit the use of cartilage tissue engineering.
Bison and cattle share several innate immunological features, some of which may actually help this animal combat shared diseases, most common of which are brucellosis, tuberculosis, anthrax, and malignant catarrhal fever [ 5- 9].
