Effect of transplanted cells with CD184 and CD26 expressions and reconstitution of CD3+ lymphocyte population on long-term survival after autologous hematopoietic stem cell transplantation for multiple myeloma.

Autologous hematopoietic stem cell transplantation (auto-SCT) is the recommended treatment for responding patients with multiple myeloma (MM). However, we do not know the risk factors influencing long-term survival without progression after auto-SCT. Therefore, this prospective study aimed to investigate the influence of transplanted cells with cluster of differentiation (CD)184+ expression, CD26+ lymphocytes and monocytes, and reconstitution of CD3+ lymphocytes on overall survival (OS) and progression-free survival (PFS) after auto-SCT in MM.

The importance of the number of transplanted cells with dipeptidyl peptidase-4 expression on the haematopoietic recovery and lymphocyte reconstitution in patients with multiple myeloma after autologous haematopoietic stem-cell transplantation.

Autologous haematopoietic stem cell transplantation (AHSCT) remains recommended treatment in the first remission in multiple myeloma (MM). In earlier research it has been suggested that there is an influence of the expression of dipeptidyl peptidase-4 (CD26) on both the homing and lymphocyte reconstitution after AHSCT. The aim of the study is to investigate the influence of transplanted cells CD26+ on the haematopoietic recovery and lymphocyte reconstitution after AHSCT in MM.

Characteristics and clinical outcome of patients with hypereosinophilia of undetermined significance.

The term "hypereosinophilia of undetermined significance" (HEus) previously known as idiopathic, benign eosinophilia relates to patients who have a long-lasting, unexplained and asymptomatic blood HE. These patients have not been studied so far in terms of demographic characteristics and clinical outcome. The aim of this study was to present the clinical characteristics and outcome of HEus patients.

Diversity of clinical manifestations and response to corticosteroids for idiopathic hypereosinophilic syndrome: retrospective study in 33 patients.

Idiopathic hypereosinophilic syndrome (IHES) is characterized by blood hypereosinophilia with no underlying cause and eosinophilia-associated organ dysfunction. Thirty-three patients, 20 female (61%) and 13 male (29%), with a median age of 56 years at diagnosis (range 16-77 years) were included in the study. The median blood eosinophilia at diagnosis was 7.

T-cell abnormalities are present at high frequencies in patients with hypereosinophilic syndrome.

Background: A T-cell clone, thought to be the source of eosinophilopoietic cytokines, identified by clonal rearrangement of the T-cell receptor and by the presence of aberrant T-cell immunophenotype in peripheral blood defines lymphocytic variant of hypereosinophilic syndrome (L-HES).

Design And Methods: Peripheral blood samples from 42 patients who satisfied the diagnostic criteria for HES were studied for T-cell receptor clonal rearrangement by polymerase chain reaction according to BIOMED-2. The T-cell immunophenotype population was assessed in peripheral blood by flow cytometry.
