Harold L Atkins, Mark S Freedman
Multiple sclerosis (MS) is thought to be an autoimmune disease targeting the central nervous system leading to demyelination, and axonal and neuronal damage, resulting in progressive disability. More intensive therapies such as immunodepletion with hematopoietic stem-cell rescue are being used at a time prior to patients becoming irreversibly disabled. Over the last 15 years, there has been a shift away from using autologous hematopoietic stem-cell transplants (aHSCT) to treat patients with progressive MS, towards treating those with active inflammation and relapses...

Despite recent advances in lymphoma treatment, mantle cell lymphoma (MCL) remains incurable and we are still unable to identify patients who will not benefit from the current standard-of-care. Here, we explore the prognostic value of recurrent genetic aberrations in diagnostic bone marrow (BM) specimens from 183 younger MCL patients from the Nordic MCL2 and MCL3 trials, which represent current standard-of-care regimens. In the univariate model, mutations of TP53 (11%) and NOTCH1 (4%), and deletions of TP53 (16%) and CDKN2A (20%) were significantly associated with inferior outcomes (together with MIPI, MIPI-c, Blastoid morphology and Ki67>30%); however, in multivariate analyses only TP53 mutations (HR=6...

BACKGROUND: Nephroblastoma and neuroblastoma belong to the most common abdominal malignancies in childhood. Similarities in the initial presentation may provide difficulties in distinguishing between these two entities, especially if unusual variations to prevalent patterns of disease manifestation occur. Because of the risk of tumor rupture, European protocols do not require biopsy for diagnosis, which leads to misdiagnosis in some cases. CASE PRESENTATION: We report on a 4½-year-old girl with a renal tumor displaying radiological and laboratory characteristics supporting the diagnosis of nephroblastoma...

Previous studies have found a connection between psychiatric problems and post-hematopoietic stem-cell transplantation (HSCT) complications. We sought to evaluate the effect of sertraline on engraftment time, hospitalization period, mortality, and post-transplantation complications in HSCT recipients with depression and/or anxiety. We recruited adults aged 18-60, who were candidates for autologous or allogeneic HSCT with major depression and/or anxiety disorder. They were administered 50 mg of sertraline or placebo daily for the first week, and then 100 mg for the following seven weeks...

Bone marrow-derived mesenchymal stem cells (BM-MSC) has been applied as the most valuable source of autologous cell transplantation for various diseases including diabetic complications. However, hyperglycemia may cause abnormalities in intrinsic BM-MSC which might lose sufficient therapeutic effects in diabetic patients. We demonstrated the functional abnormalities in BM-MSC derived from both type 1 and type 2 diabetes models in vitro, which resulted in loss of therapeutic effects in vivo in diabetic nephropathy (DN)...

REVIEW
Bita Fakhri, Brad Kahl
Mantle cell lymphoma (MCL) is a B-cell non-Hodgkin lymphoma with typically aggressive behavior. The genetic signature is the chromosomal translocation t(11;14)(q13;q32) resulting in overexpression of cyclin D1. Asymptomatic newly diagnosed MCL patients with low tumor burden can be closely observed, deferring therapy to the time of disease progression. Although MCL classically responds to upfront chemotherapy, it remains incurable with standard approaches. For patients in need of frontline therapy, the initial decision is whether to proceed with an intensive treatment strategy or a non-intensive treatment strategy...

Mucormycosis is a life threatening fungal infection and remains an important cause of morbidity and mortality in immunocompromised patients after hematopoietic stem cell transplant. We report here a case of hepatosplenic mucormycosis in a patient after autologous stem cell transplant. A young man with anaplastic large cell lymphoma underwent autologous hematopoietic stem cell transplant after achieving complete remission with standard chemotherapy and consolidative radiotherapy. He was found to have incidental hepatosplenic hypodensities on follow up imaging, that were proved to be mucormycosis on histopathology after getting CT-guided biopsy of splenic lesions...

Autologous fat transplantation has been applied widely in clinic. However, the low survival rate is still a problem to be solved. Studies shows that the human adipose-derived stem cells (ADSCs) transfected by vascular endothelial growth factor (VEGF) can improve the survival rate of autologous fat transplantation. Our study is to evaluate the effects of the conditioned medium of VEGF-transfected human adipose-derived stem cells (VEGF-ADSCs-CM) on fat transplantation. ADSCs were isolated and transfected with MOI = 40...

Among patients with immunoglobulin light chain (AL) amyloidosis, there is little consensus on when reinstitution of chemotherapy should occur. We conducted a retrospective study to evaluate the patterns of relapse or progression (R/P) and the timing of re-initiating therapy among 235 patients initially treated with ASCT at Mayo Clinic. The median time from ASCT to second-line therapy was 24.3 months. At the time of restarting therapy, median dFLC was 9.9 mg/dL (42% of diagnosis value); 32% had a dFLC< 5mg/dL; and 63% met criteria for organ R/P...

Background Multiple myeloma is a haematological blood cancer of the bone marrow and is classified by the World Health Organisation (WHO) as a plasma cell neoplasm. In multiple myeloma, normal plasma cells transform into malignant myeloma cells and produce large quantities of an abnormal immunoglobulin called monoclonal protein or M protein. This ultimately causes multiple myeloma symptoms such as bone damage or kidney problems. The annual worldwide incidence of multiple myeloma is estimated to be 6 - 7/100,000 and accounts for 1% of all cancer...

PURPOSE OF REVIEW: Since the discovery two decades ago that programmable endonucleases can be engineered to modify human cells at single nucleotide resolution, the concept of genome editing was born. Now these technologies are being applied to therapeutically relevant cell types, including hematopoietic stem cells (HSC), which possess the power to repopulate an entire blood and immune system. The purpose of this review is to discuss the changing landscape of genome editing in hematopoietic stem cells (GE-HSC) from the discovery stage to the preclinical stage, with the imminent goal of clinical translation for the treatment of serious genetic diseases of the blood and immune system...

Patients with multiple myeloma (MM) who undergo autologous stem cell transplantation (ASCT) are susceptible to severe infections. Low levels of circulating mannan-binding lectin (MBL) are associated with increased risk of infection. In this prospective study, we evaluated 100 patients who underwent ASCT regarding the effect of MBL on the incidence and severity of febrile episodes. Seventeen patients had MBL levels <500 ng/mL (11 received antibiotic prophylaxis and 6 did not). Although there was no statistical difference regarding the development of febrile episodes between patients with low and normal MBL, among 17 patients with low MBL levels, six out of eleven patients who received antibiotic prophylaxis developed a febrile episode compared with six out of six patients who did not receive antibiotic prophylaxis and developed a febrile episode...

Transplantation of small cord blood (CB) units, or of autologous ex vivo-genetically modified adult hematopoietic stem cells (HSC), face the common challenge of suboptimal HSC doses for infusion and impaired engraftment of the transplanted cells. Ex vivo expansion of HSCs, using either cell-based coculture approaches or especially small molecules have been successfully tested mainly in CB and in prolonged cultures. Here, we explored whether innovative combinations of small molecules can sufficiently, after short culture, expand adult HSCs while retaining their functionality in vivo...

Previous Fanconi anemia (FA) gene therapy studies have failed to demonstrate engraftment of gene corrected hematopoietic stem and progenitor cells (HSPC) from FA patients, either after autologous transplantation or infusion into immunodeficient mice. In this study we demonstrate that a validated short transduction protocol of G-CSF plus plerixafor-mobilized CD34(+) cells from FA-A patients with a therapeutic FANCA-lentiviral vector corrects the phenotype of in vitro cultured hematopoietic progenitor cells. Transplantation of transduced FA CD34(+) cells into immunodeficient mice resulted in reproducible engraftment of myeloid, lymphoid and CD34(+) cells...

Autologous hematopoietic stem cell transplantation (Auto- HSCT) improves survival in multiple myeloma (MM) and Non-Hodgkin lymphoma (NHL). Traditionally, filgrastim (Neupogen® - recombinant G-CSF) has been used in as a single agent or in combination with plerixafor for stem cell mobilization for auto-HSCT. In Europe, recombinant G-CSF biosimilar (Tevagrastim®) is approved for various indications similar to reference filgrastim, including stem cell mobilization for auto-HSCT; However, tbo- Filgrastim (Granix®) is registered under original biologic application and is not approved for stem cell mobilization in the USA...

Lenalidomide (Revlimid(®)) is an immunomodulatory drug with multiple mechanisms of action against multiple myeloma. It is a thalidomide analogue, with improved potency and reduced toxicity compared with thalidomide. In the EU and USA, lenalidomide monotherapy is indicated for the maintenance treatment of patients with newly diagnosed multiple myeloma who have undergone autologous stem-cell transplantation (ASCT). In the pivotal, phase 3 IFM 2005-02 and CALGB 100104 trials, lenalidomide maintenance therapy after ASCT administered until disease progression significantly prolonged progression-free survival (PFS; primary endpoint) relative to placebo in patients with newly diagnosed multiple myeloma...

The diagnostic criteria for follicular lymphoma (FL) transformation vary among the largest series, which commonly exclude histologically-documented transformation (HT) mandatorily. The aims of this retrospective observational multicentre study by the Spanish Grupo Español de Linfoma y Transplante Autólogo de Médula Ósea, which recruited 1734 patients (800 males/934 females; median age 59 years), diagnosed with FL grades 1-3A, were, (i) the cumulative incidence of HT (CI-HT); (ii) risk factors associated with HT; and (iii) the role of treatment and response on survival following transformation (SFT)...
