BACKGROUND: Fanconi anaemia (FA) is an inherited disease with bone marrow failure, variable congenital and developmental abnormalities, and cancer predisposition. With improved survival, non-haematological manifestations of FA become increasingly important for long-term management. While renal abnormalities are recognized, detailed data on patterns and frequency and implications for long-term management are sparse. METHODS: We reviewed clinical course and imaging findings of FA patients with respect to renal complications in our centre over a 25-year period to formulate some practical suggestions for guidelines for management of renal problems associated with FA...

Epidemiological data on late noninfectious pulmonary complications (LONIPCs) following allogeneic haematopoietic stem cell transplantation (HSCT) are derived exclusively from retrospective studies and conflicting. We aimed to evaluate prospectively their incidence, risk factors and outcomes.All consecutive patients scheduled to receive allogeneic HSCT between 2006 and 2008, at the university-teaching Saint Louis Hospital (Paris, France) were screened for inclusion. Eligible patients were those surviving at day 100...

PURPOSE: In patients with follicular lymphoma, secondary transformation to aggressive lymphoma (tFL) implies a poor prognosis. In principle, allogeneic haematopoietic cell transplantation (allo-HCT) offers a chance of cure for tFL but is rarely practiced. Aim of this retrospective multicenter study was to define the actual significance of allo-HCT in treatment of tFL. METHODS: The database of the German Registry for Stem Cell Transplantation (DRST) was screened for patients who underwent allo-HCT for tFL 1998-2008...

BACKGROUND: The highly plastic nature of adrenal cortex suggests the presence of adrenocortical stem cells (ACSC) but the exact in vivo identity of ACSC remains elusive. A few studies have demonstrated the differentiation of adipose or bone marrow-derived mesenchymal stem cells (MSC) into steroid-producing cells. We therefore investigated the isolation of multipotent MSC from human adrenal cortex. METHODS: Human adrenals were obtained as discarded surgical material...

Natural killer (NK) cells are cytotoxic members of type I innate lymphocytes (ILC1) with a prominent role in anti-tumor and anti-viral immune responses. Despite the increasing insight into NK cell biology, the steps and stages leading to mature circulating NK cells require further investigation. Natural killer cell development and functional maturation are complex and multi-stage processes that occur predominantly in the bone marrow (BM) and originate from haematopoietic stem cells CD34+ (HSC). Within the BM, NK cell precursor (NKP) and NK cell development intermediates reside in specialized niches that are characterized by particular cellular components that provide signals required for their maturation...

Tandem stem cell transplantation (SCT) is an option for high-risk relapsed/refractory Hodgkin Lymphoma (HL) patients. We evaluated the tolerance/efficacy of double autologous or autologous SCT (ASCT) followed by allogenic SCT (alloSCT) in 120 HL patients prospectively registered on a French nationwide database. Median age was 26 (14-56) years. Complete remission rate was 60%, including 33% after a single line, and another 27% after two or more salvage regimens. Partial response rate was 32%, and 8% suffered treatment failure...

Granulocyte colony-stimulating factor (G-CSF) has been widely used in the field of allogeneic haematopoietic stem cell transplantation (allo-HSCT) for priming donor stem cells from the bone marrow (BM) to peripheral blood (PB) to collect stem cells more conveniently. Donor-derived natural killer (NK) cells have important antitumour functions and immune regulatory roles post-allo-HSCT. The aim of this study was to evaluate the effect of G-CSF on donors' NK cells in BM and PB. The percentage of NK cells among nuclear cells and lymphocyte was significantly decreased and led to increased ratio of T and NK cells in BM and PB post-G-CSF in vivo application...

Paediatric therapy-related acute myeloid leukaemia (t-AML) is rare and the outcome is poor. While allogeneic haematopoietic stem cell transplantation (HSCT) is generally the accepted modality of treatment, data regarding salvage chemotherapy, remission induction, conditioning regimens, transplant-related mortality and outcome is scarce. Between 2000 and2016, 36 children with t-AML were treated in seven UK paediatric HSCT centres. The most common salvage protocol for remission induction was FLAG with or without idarubicin and 28 patients were in complete morphological remission prior to BMT...

Sickle cell disease (SCD) is a group of inherited disorders caused by mutations in HBB, which encodes haemoglobin subunit β. The incidence is estimated to be between 300,000 and 400,000 neonates globally each year, the majority in sub-Saharan Africa. Haemoglobin molecules that include mutant sickle β-globin subunits can polymerize; erythrocytes that contain mostly haemoglobin polymers assume a sickled form and are prone to haemolysis. Other pathophysiological mechanisms that contribute to the SCD phenotype are vaso-occlusion and activation of the immune system...

Ageing of haematopoietic stem cells (HSCs) contributes to deficits in the aged haematopoietic system. HSC decline is driven in part by DNA damage accumulation; yet, how ageing impacts the acute DNA damage response (DDR) of HSCs is poorly understood. We show that old HSCs exhibit diminished ATM activity and attenuated DDR, leading to elevated clonal survival in response to a range of genotoxins that was underwritten by diminished apoptotic priming. Distinct HSC subsets exhibited ageing-dependent and subtype-dependent differences in apoptotic priming and survival in response to DNA damage...

INTRODUCTION: While myeloma is an incurable malignancy, developments in disease management have led to increased life expectancy in recent years. Treatment typically involves stem-cell transplantation. Increased survival rates equate to more patients living with the burden of both the disease and its treatment for increasing number of years, rendering myeloma a long-term condition.Evidence exists to demonstrate the benefits of exercise for patients recovering from stem-cell transplantation, and prehabilitation-exercise before treatment-has been shown to be effective in other disease areas...

Secondary malignancy post haematopoietic stem cell transplantation (HSCT) for malignant disorders is well recognized. There are very few published reports on malignancy post HSCT for Primary Immunodeficiency (PID). We report 12 cases of 944 patients, who developed non-PTLD malignancy post-HSCT for PID.

The inherited form of Severe Chronic Neutropenia called Severe Congenital Neutropenia (SCN) is an intrinsic defect of neutrophils maturation. SCN affected patients are at risk to develop lethal in-fections and to transform into myelodisplasia (MDS) and/or acute laeukemia(AL). Use of Granulocyte-Colony-Stimulating Factor (G-CSF) has significantly improved the prognosis of affected patients, but the only definitive cure for the disease is Haematopoietic Stem Cell Trans-plantation (HSCT). Overall Survival of SCN patients has been assessed at around 85% after 3 years from transplantation ...

Naive T cells have long been regarded as a developmentally synchronized and fairly homogeneous and quiescent cell population, the size of which depends on age, thymic output and prior infections. However, there is increasing evidence that naive T cells are heterogeneous in phenotype, function, dynamics and differentiation status. Current strategies to identify naive T cells should be adjusted to take this heterogeneity into account. Here, we provide an integrated, revised view of the naive T cell compartment and discuss its implications for healthy ageing, neonatal immunity and T cell reconstitution following haematopoietic stem cell transplantation...
