OBJECTIVE: The role of B-cells and the subgroup of IL-10 producing B-cells, known to have a regulatory function, in patients following a haematopoetic stem cell transplant (alloSCT) has not been clearly understood to date. METHODS: We prospectively recruited 95 patients following an alloSCT and studied the B-cell reconstitution on days 30, 90 and 150. Regulatory B10-cells could be analysed in 22 consecutively recruited patients on day 30 post transplant. RESULTS: The total B-cell percentages in transplant recipients (median 0...

The management of chronic myeloid leukaemia (CML) has changed extensively over the past 15 years. Prior to the development of targeted therapies and in the absence of allogeneic haematopoetic stem-cell transplantation (HSCT), the median survival was 5-7 years. HSCT was quickly established as the standard of care for eligible patients through the 1980s and 1990s, when considerable advances were made in the optimization of conditioning regimens and supportive care. Exploiting a deeper understanding of the molecular basis of CML, the development of tyrosine kinase inhibitors (TKIs) in the late 1990s revolutionized the management of the disease...

BACKGROUND: X-linked adrenoleukodystrophy (X-ALD) is a peroxisomal metabolic disorder. Male patients develop adrenocortical insufficiency (80 % before 18 years), a chronic myelopathy (adrenomyeloneuropathy (AMN); all in adulthood), or progressive cerebral demyelination (cerebral ALD; 40 % before 18 years). Cerebral ALD is treated with haematopoetic cell transplantation (HCT). It is unknown if AMN still develops in patients with X-ALD that underwent HCT for cerebral ALD in childhood. PATIENTS AND METHODS: A retrospective observational study was performed by selecting all adult patients with X-ALD in our cohort that underwent HCT in childhood...

High-dose chemotherapy followed by autologous haematopoetic stem cell transplantation (ASCT) is a standard frontline therapy for multiple myeloma (MM). Unfortunately, there are no randomized clinical studies examining the role of a second ASCT in patients who relapse after the initial autotransplant. Analysing all available retrospective studies, it seems that salvage ASCT can safely be performed in most patients with an overall treatment-related mortality rate <5%. Approximately 65% of patients will achieve an objective response and progression-free and overall survival will be around 12 months and 32 months, respectively...

BACKGROUND: There is lack of consensus regarding whether both upper and lower endoscopic examinations are required for diagnosis of gastrointestinal acute graft versus host disease (GI-AGVHD). AIM: To evaluate the impact of endoscopic procedures on the diagnosis of GI-AGVHD. METHODS: We performed a retrospective case-control study of recipients of allogeneic haematopoetic cell transplant (HCT) from 2000 to 2011, who presented with GI symptoms between 20 and 125 days post-HCT...

Ex vivo expansion of haematopoetic cells by application of specific cytokines is one approach to overcome boundaries in cord blood transplantation due to limited numbers of haematopoetic stem cells. While many protocols describe an effective increase of total cell numbers and the amount of CD34-positive cells, it still remains unclear if and how the procedure actually affects the cells' properties. In the presented publications, CD34-positive cells were isolated from cord blood and expanded for up to 7 days in media supplemented with stem cell factor (SCF), thrombopoietin (THPO), interleukin 6 (IL-6), and fms-related tyrosine kinase 3 ligand (FLT3lg)...

Interleukin-1 (IL-1) is a key regulator of inflammation and ischaemic brain injury, but the contribution of central and peripheral sources of IL-1 to brain injury is not well understood. Here we show that haematopoietic-derived IL-1 is a key driver of ischaemic brain injury. Wild type (WT) mice transplanted with IL-1αβ-deficient bone marrow displayed a significant (40%) reduction in brain injury induced by focal cerebral ischaemia compared with WT mice transplanted with WT bone marrow. This was paralleled by improved neurological outcome and the almost complete absence of splenic-derived, but not liver-derived, IL-1α after stroke in WT mice lacking haematopoietic-derived IL-1...

Uraemia causes inflammation and reduces immune system function as evidenced by an increased risk of viral-associated cancers, increased susceptibility to infections and decreased vaccination responses in patients with end-stage renal disease (ESRD). The substantially increased risk of atherosclerosis in these patients is also probably related to uraemia-associated inflammation. Uraemia is associated with a reduction in the number and function of lymphoid cells, whereas numbers of myeloid cells in uraemic patients are normal or increased with increased production of inflammatory cytokines and reactive oxygen species...

Rheumatoid arthritis (RA) is a chronic destructive autoimmune disease characterised by periods of flare and remission. Today's treatment is based on continuous immunosuppression irrespective of the patient's inflammatory status. When the disease is in remission the therapy is withdrawn but withdrawal attempts often results in inflammatory flares, and re-start of the therapy is commenced when the inflammation again is prominent which leads both to suffering and increased risk of tissue destruction. An attractive alternative treatment would provide a disease-regulated therapy that offers increased anti-inflammatory effect during flares and is inactive during periods of remission...

Mitochondrial neurogastrointestinal encephalomyopathy is a rare multisystemic autosomic recessive disorder characterized by: onset typically before the age of 30 years; ptosis; progressive external ophthalmoplegia; gastrointestinal dysmotility; cachexia; peripheral neuropathy; and leucoencephalopathy. The disease is caused by mutations in the TYMP gene encoding thymidine phosphorylasethymine phosphorylase. Anecdotal reports suggest that allogeneic haematopoetic stem cell transplantation may be beneficial for mitochondrial neurogastrointestinal encephalomyopathy, but is associated with a high mortality...

The myelodisplastic syndrome is a heterogeneous group of diseases, characterised by ineffective and dysplastic haematopoesis and pancytopenia in the peripheral blood, followed by progressive disturbance of differentiation of the haematopoetic stem cell, resulting in evolution of the disease towards acute leukaemia. According to the latest WHO classification, the term myelodisplastic syndrome includes diseases with an indolent course, as well as diseases with a fast evolution towards acute leukaemia. Because of this diversity, haematologists base their therapeutic decisions on prognostic scoring systems which incorporate all the significant factors with an influence on survival in this group of patients with myelodisplastic syndrome...

BK virus (BKV)-associated hemorrhagic cystitis (HC), varying from mild hematuria with or without dysuria to life-threating bleeding and clots that may cause urinary obstruction and renal failure, causes significant morbidity and mortality in haematopoetic stem cell transplanted (HSCT) patients. Unfortunately, its development is difficult to predict since BK viruria is very common after HSCT and can be present in patients with and without HC. There is therefore the need to identify risk factors that may increase the risk of developing HC after HSCT...

The therapeutic success of haematopoetic stem and progenitor cell (HSPC) transplantation is critically dependent on HSPC engraftment in the bone marrow. Gradients of stromal cell-derived factor 1 (SDF1) direct HSPC homing, both in vitro and in vivo. Potentially, regulating the delivery levels of exogenous SDF1 applied to the bone marrow could augment HSPC engraftment. Thus, the aim of the present study was to revise the ability of biocompatible hydrogels to direct HSPC migration in vitro. The delivery system of choice is based on heparin cross-linked with collagen1...

Killer cell immunoglobulin-like receptors (KIRs) influence the outcome of haematopoetic stem cell transplantation by modulating the cytotoxic ability of natural killer (NK) cells and a subset of T cells. KIRs are also highly polymorphic and could therefore be good population genetic markers, much like their human leukocyte antigen (HLA) ligands. This study represents the first report on distribution of 16 KIR genes in 162 unrelated healthy Saudi individuals. All the 16 KIR genes were observed in the studied population and the four framework genes (KIR2DL4, 3DL2, 3DL3 and 3DP1) were present in all individuals...

Haematopoietic stem cell transplant (HSCT) recipients lose immune memory of exposure to infectious agents and vaccines accumulated throughout their lifetime and therefore need to be revaccinated. We aimed to evaluate the influence of different factors on hepatitis A virus (HAV) immunity in both child and adult HSCT recipients living in an intermediate endemic region, Turkey. Eighty patients (age range 2·5-57 years) who had HAV serology prior to HSCT were evaluated. The prevalence of HAV seropositivity was 85% (n=68) before HSCT...

Cytomegalovirus (CMV) is an important factor for morbidity and long-term outcome after allogeneic haematopoetic stem cell transplantation (allo-SCT). Cases of proven and probable CMV infection and disease among 97 allo-SCT recipients in Gothenburg, Sweden, 1997-2001, were analysed. CMV DNAemia was detected in 60 patients at a median of 30 days after SCT. Four patients (4%) had CMV disease; 2 had proven and 2 had probable CMV disease. Of these 4 patients, 1 died of CMV disease. In 1 additional patient, CMV was considered to have contributed to the patient's death...
