A comparison between metabolic syndrome post-hematopoietic stem cell transplantation and spontaneously occurring metabolic syndrome.

Background: Hematopoietic stem cell transplantation (HSCT) is used in the treatment of several hematological and non-hematological disorders. An increasing number of long-term survivors recover from their primary disease, but they are at risk of adverse late effects, including metabolic syndrome (MS), which seems to be common in long-term survivors of HSCT.

Aim: To compare common metabolic parameters and adipohormone profiles in post-transplant and spontaneously occurring or "classic" MS patients.

Second malignancies in essential thrombocythemia (ET): a retrospective analysis of 331 patients with long-term follow-up from a single institution.

Essential thrombocythemia (ET) is a myeloproliferative disorder characterized by an indolent clinical course, with a median survival exceeding 20 years. A minority of patients undergo thrombohemorrhagic complications, which might be prevented by cytoreductive treatment in high risk categories. Alkylating agents (ALK) have been demonstrated to increase the risk of acute leukemia and myelodysplastic syndromes in patients with myeloproliferative disorders, whereas the potential oncogenicity of hydroxyurea (HU) remains a matter of debate.

Prevalence of metabolic syndrome in long-term survivors of hematopoietic stem cell transplantation.

Our purpose was to determine the prevalence and features of metabolic syndrome (MS) in a series of long-term hematopoietic stem cell transplantation (HSCT) survivors. We assessed the clinical, metabolic and endocrinological data, and plasma TNF, leptin, resistin and adiponectin levels relating to 85 HSCT recipients. MS was diagnosed on the basis of the National Cholesterol Education Program-Adult Treatment Panel III criteria.

Autologous haematopoietic stem cell transplantation without CD34+ cell selection in refractory Crohn's disease.

Objectives: Autologous haematopoietic stem cell transplantation (HSCT) with CD34(+) cell selection has recently been used in the treatment of refractory Crohn's disease, showing good safety and promising efficacy. We investigated the safety and efficacy of HSCT with unselected peripheral blood stem cells (PBSCs) in moderate-severe refractory Crohn's disease.

Patients: Four patients (three male, one female; age range 26-45 years) with active moderate-severe Crohn's disease (median Crohn's Disease Activity Index (CDAI) 319, range 272-345), refractory or intolerant to multiple drugs including infliximab, were enrolled.
