Maciejewski, M.D., Ph.D., and Satu Mustjoki, M.D., Ph.D.: Somatic STAT3 Mutations in Large Granular Lymphocytic Leukemia T-cell large granular lymphocytic leukemia was initially referred to as a clonal disorder of large granular lymphocytes involving blood, bone marrow, spleen, and liver.1 This disorder is seen as a the presence of abnormal CD3+CD8+CD57+ lymphocytes corresponding to activated effector cytotoxic T lymphocytes .2,3 Huge granular lymphocytic leukemia is generally accompanied by autoimmune processes such as arthritis rheumatoid and immune-mediated cytopenias.4 Many cases are indolent, and distinguishing large granular lymphocytic leukemia from reactive processes involving large granular lymphocytosis could be difficult, since both conditions can be associated with a skewed CTL antigen-receptor repertoire and will be linked to viral attacks and autoimmune conditions.9 Thus, large granular lymphocytic leukemia may symbolize an extreme pole in the spectrum of CTL responses to antigen.
Because of ethical, logistical, and monetary constraints, no randomized trial provides been conducted to clarify the indications for operation and the timing of it that could connected with favorable outcomes.4 The Early Medical operation versus Conventional Treatment in Infective Endocarditis trial was made to compare the clinical outcomes of early surgical procedure with those of a conventional-treatment technique that is founded on current recommendations for patients with left-sided infective endocarditis and a higher threat of embolism. The major hypothesis of this trial was that early operation would decrease the death rate or embolic events, in comparison with conventional treatment. Methods Study Design We conducted this prospective, randomized trial involving individuals with infective endocarditis who were applicants for both early surgery and conventional treatment in two medical centers in Korea.
