Immunomodulatory effects of unselected haematopoietic stem cells autotransplantation in refractory Crohn's disease.

Background: Autologous haematopoietic stem cells transplantation (HSCT) has been shown to be effective in refractory Crohn's disease.

Aim: We analysed the effects of HSCT on the immune response of patients treated for moderate-severe Crohn's disease, refractory or intolerant to multiple drugs.

Methods: Unselected peripheral blood stem cells were collected after mobilisation with cyclophosphamide (CTX) and G-CSF.

Risk factors and severe outcome in thrombotic microangiopathy after allogeneic hematopoietic stem cell transplantation.

Background: Thrombotic microangiopathy (TMA) has been described as severe complication after hematopoietic stem cell transplantation (HSCT). The principal aim of this study was to focus the incidence and the outcome of TMA in the era of more complex HSCTs.

Methods: We analyzed the role of some predicting factors for the incidence and the outcome of TMA after HSCT.

A long-term follow-up analysis in adult acute myeloid leukemia patients after hematopoietic stem cell transplantation.

Aims And Background: Over the last 17 years, 119 adult acute myeloid leukemia patients have undergone hematopoietic stem cell transplantation at our Center.

Study Design: Seventy patients in first complete remission received hematopoietic stem cell transplantation (28 allogeneic and 42 autologous HSCT) as late intensification after conventional chemotherapy; 38 patients received allogeneic hematopoietic stem cell transplantation in a more advanced phase. A reference group was built up by collecting 40 acute myeloid leukemia patients who received high-dose cytosine arabinoside as late intensification and whose complete remission lasted more than 10 months.

Hematopoietic stem cell transplantation in adult acute lymphoblastic leukemia: a single-centre analysis.

The role of autologous or allogeneic hematopoietic stem cell transplantation (HSCT) in ALL is controversial because of its adverse risk/benefit ratio, and the main policy is to reserve it for high-risk patients. In our Institution, between 1984 and 2002, 40 patients received an allogeneic HSCT and 39 underwent autografting. The conditioning regimen included HD-Ara-C, HD-CTX and 10 Gy fractionated TBI.

Harvesting of autologous blood stem cells after a mobilising regimen with low-dose cyclophosphamide.

Although high-dose cyclophosphamide (HD-CTX) is commonly used as a mobilising regimen for autologous peripheral blood stem cell (PBSC) collection, significant morbidity and insufficient harvesting may complicate the procedure. Alternative regimens and lower doses of cyclophosphamide (CTX) have been investigated as possible ways of overcoming these difficulties. Low-dose CTX (1.

Lethal pulmonary complications significantly correlate with individually assessed mean lung dose in patients with hematologic malignancies treated with total body irradiation.

Purpose: To assess the impact of lung dose on lethal pulmonary complications (LPCs) in a single-center group of patients with hematologic malignancies treated with total body irradiation (TBI) in the conditioning regimen for bone marrow transplantation (BMT).

Methods: The mean lung dose of 101 TBI-conditioned patients was assessed by a thorough (1 SD around 2%) in vivo transit dosimetry technique. Fractionated TBI (10 Gy, 3.
