BACKGROUND: Large, multicenter studies comparing commonly used reduced-intensity conditioning (RIC) approaches in follicular lymphoma (FL) have not been performed. Using the CIBMTR database, we report the outcomes of two most commonly used RIC approaches, fludarabine and busulfan (Flu/Bu) vs. fludarabine, cyclophosphamide and rituximab (FCR) in FL patients. METHODS: We evaluated 200 FL patients undergoing allogeneic hematopoietic cell transplantation (allo-HCT) who received RIC with either Flu/Bu (n=98) or FCR (n=102) during 2008-2014...

BACKGROUND: Reduced intensity conditioning regimens (RIC) for hematopoietic stem cell transplantation (HCT) can reduce morbidity and mortality, but patients with advanced disease may require alternate approaches. In an initial report of RIC (Fludarabine (FLU) and Melphalan (MEL)) with total-marrow-lymphoid irradiation (TMLI) in HCT for advanced hematological malignancies in 33 patients, we found the addition of TMLI to RIC was feasible and safe. Here we report long-term outcomes for these patients...

Moussab Damlaj, Mrinal M Patnaik
The advent of reduced intensity conditioning (RIC) in the 1990's has expanded accessibility to transplant thereby permitting previously ineligible patients to receive such therapy. Consensus guidelines defining dose intensity were subsequently developed (1, 2). Fludarabine combined with intermediate dose busulfan (FB) or intermediate dose melphalan (FM) are the most commonly used RIC regimens. Although these protocols are considered equivalent in terms of myelosuppressive and immunosuppressive properties, there is no prospective comparative data to further guide their use...

Background: Oligodendrocyte cell death is among the important features of spinal cord injury, which appears within 15 min and occurs intensely for 4 h after injury, in the rat spinal contusion model. Accordingly, the number of oligodendrocytes is progressively reduced within 24 h after injury. Administration of oligodendrocyte-like cells (OLCs) into the lesion area is one of the approaches to counterbalance this condition. Methods: Bone marrow stromal cells were transdifferentiated into neurospheres and then into neural stem cells and later were differentiated into OLCs using triiodothyronine and transplanted into the spinal cord contusion rats...

OBJECTIVES: Weaning from mechanical ventilation after liver transplant can be demanding. In selected cases, tracheostomy is helpful. The optimal timing for tracheostomy in ventilator-dependent liver transplant recipients is not well known. MATERIALS AND METHODS: We retrospectively analyzed data of 447 patients who had undergone liver transplant in our hospital. Thirty-nine patients who had high risk of prolonged mechanical ventilation according to the Respiratory Risk Score were identified from 95 patients who received tracheostomy after liver transplant...

PURPOSE: To assess the effect of dry eye disease (DED) in graft donors on dendritic cell (DC) maturation, host T-cell sensitization, and corneal allograft rejection. METHODS: Corneas of control (healthy donor) and DED mice (C57BL/6) were transplanted onto fully allogeneic naive BALB/c recipients (n = 10 mice/group). Long-term allograft survival was evaluated for 8 weeks. Corneas and draining lymph nodes (dLNs) were harvested at posttransplantation day 14 (n = 5 mice/group)...

INTRODUCTION: Orthotopic liver transplantation (OLT) has emerged as the mainstay of treatment for end-stage liver disease. In an attempt to improve the availability of donor allografts and reduce waiting list mortality, graft acceptance criteria were extended increasingly over the decades. The use of extended criteria donor (ECD) allografts is associated with a higher incidence of primary graft non-function and/or delayed graft function. As such, several strategies have been developed aiming at reconditioning poor quality ECD liver allografts...

Different conditioning regimens have been evaluated in matched-related donor allogeneic hematopoietic stem cell transplantation (allo-HSCT) for acquired severe aplastic anemia (SAA) with varying results. In this manuscript, we report our experience with fludarabine (120mg/m(2)), very low dose cyclophosphamide (1200mg/m(2)) and antithymocyte globulin (7.5mg/kg). Low dose total body irradiation (2Gy) was added to the conditioning regimen for patients older than 15 years. Nineteen patients (median age 23years) underwent transplant between 2008 and 2015...

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is incurable with conventional therapies. Limited retrospective data have shown durable remissions after haematopoietic cell transplantation (HCT) [allogeneic (allo) or autologous (auto)]. We conducted a multicentre retrospective study in BPDCN patients treated with allo-HCT and auto-HCT at 8 centres in the United States and Canada. Primary endpoint was overall survival (OS). The population consisted of 45 consecutive patients who received an allo-HCT (n = 37) or an auto-HCT (n = 8) regardless of age, pre-transplant therapies, or remission status at transplantation...

Although Hodgkin lymphoma is a disease with a low incidence rate, there is a significant social resources perspective associated with this disease to ensure that adolescents and young adults are adequately treated and receive social reintegration. Consequently, Hodgkin lymphoma is considered an important disease in the field of oncology. Combined modality therapy, which combines chemotherapy and radiotherapy, has resulted in cure rates of more than 80% in patients with early stages of this disease, although long-term sequelae remain a problem...

RATIONALE AND AIM: Little is known about persistent pain after lung transplantation. Therefore, the aim was to present a multidimensional assessment of self-reported pain 1-5 years after lung transplantation and its relationship with fatigue and transplant-specific well-being. METHODS: This nationwide, cross-sectional cohort study is part of the self-management after thoracic transplantation study. A total of 117 lung recipients, all White, who were due for their annual follow-up at one (n = 35), two (n = 28), three (n = 23), four (n = 20) and 5 years (n = 11) after lung transplantation were included...

Deficiency of adenosine deaminase 2 (DADA2) is caused by biallelic deleterious mutations in CECR1 DADA2 results in variable autoinflammation and vasculopathy (recurrent fevers, livedo reticularis, polyarteritis nodosa, lacunar ischemic strokes and intracranial hemorrhages), immunodeficiency and bone marrow failure. TNF-α blockade is the treatment of choice for the autoinflammation and vascular manifestations. Hematopoietic stem cell transplantation (HSCT) represents a potential definitive treatment. We present a cohort of 14 patients from 6 countries who received HSCT for DADA2...

Stem cell transplantation is indicated in hematological malignancies as well as some solid tumors and congenital abnormalities. Autologous transplantation allows the administration of high dose chemotherapy without prolonged bone marrow aplasia. Allogeneic transplantation allows us to give the patient a new immune system that can locate and destroy remaining tumor cells. First attempts in patients began in 1939. Improved outcomes occurred after discovering the human leukocyte antigen system which allowed for matching the donor to the patient...

Dyskeratosis congenita is a rare congenital telomeropathy characterized by cutaneous and nail dystrophy, oral leukoplakia, and bone marrow failure. Pulmonary fibrosis and cancers are late manifestations. Allogeneic hematopoietic stem cell transplant represents the only cure for those with bone marrow failure with this disease, but outcomes reported are overall poor, with organ toxicities, graft failure, and graft-versus-host disease as main issues. Although reduced intensity conditioning regimens seem to be related to better outcomes, a standard regimen for dyskeratosis congenita has never been defined...

Ex vivo CD 34+ selection prior to allogeneic hematopoietic stem Cell transplantation (allo-HCT) reduces GVHD without increasing relapse, but usually requires myeloablative conditioning. We aimed to identify toxicity patterns in older patients & the association with overall survival (OS) & non-relapse mortality (NRM). We conducted a retrospective analysis of 200 pts who underwent CD34+ selection allo-HCT using the ClinicMACS® system between 2006-2012. All grade 3-5 toxicities by CTCAE v4.0 were collected. Eighty patients ≥ 60yrs with a median age of 64 (range 60-73) were compared to 120 pts <60yrs...

Investigations based on mesenchymal stem cells (MSCs) for osteoporosis have been obtained intensive attention recently. MSCs can derive from various tissues, such as bone marrow, adipose, umbilical cord, placenta, dental pulp, etc. Among them, dental pulp derived MSCs (DPSCs) and hepatocyte growth factor (HGF)-modified DPSCs (DPSCs-HGF) highly expressed osteogenic related genes and have stronger osteogenic differentiation capacities. DPSCs have more benefits in treating osteoporosis. The purpose of this study is to investigate the roles of HGF gene modified DPSCs in bone regeneration using a mouse model of ovariectomy (OVX)-induced bone loss...

Allogeneic stem cell transplantation with HLA-matched donors is increasingly used for older patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). It remains unclear if haploidentical stem cell transplantation (haploSCT) is a suitable option for older patients with this disease. We analyzed 43 patients with AML/MDS (median age, 61 years) who underwent a haploSCT at our institution. All patients received a fludarabine-melphalan-based reduced-intensity conditioning regimen and post-transplant cyclophosphamide-based graft-versus-host disease (GVHD) prophylaxis...
