Cryptochrome-1 expression: a new prognostic marker in B-cell chronic lymphocytic leukemia
Chronic lymphocytic leukemia is an adult-onset leukemia with a heterogeneous clinical behavior. When chronic lymphocytic leukemia cases were divided on the basis of IgVH mutational status, widely differing clinical courses were revealed. Since IgVH sequencing is difficult to perform in a routine diagnostic laboratory, finding a surrogate for IgVH mutational status seems an important priority. In the present study, we proposed the use of Cryptochrome- 1 as a new prognostic marker in early-stage chronic lymphocytic leukemia. Seventy patients (Binet stage A, without treatment) were included in the study. We correlated Cryptochrome-1 mRNA with well established prognostic markers such as IgVH mu…
Deficit of interleukin 7 in septic patients.
We recently demonstrated an overall decrease of all αβ and specially γδ T cell subsets in patients with sepsis compared with healthy subjects. IL-7 is a crucial factor for development of γδ T cells and survival in sepsis but its association with sepsis severity, evolution of organ failure and death still has not been investigated. Sera from 78 patients who met criteria for sepsis were analyzed vs control group. Septic patients showed the lowest levels of IL-7. Patients with severe sepsis reached levels of IL-7 higher than those observed in the groups of uncomplicated sepsis and septic shock. The frequency of γδ T cells at admission was lower in septic patients vs control group. At the time …
