Fatal acute graft-versus-host disease in Sézary Syndrome treated with Mogamulizumab and hematopoietic cell transplantation.

Sézary syndrome (SS) is a rare and aggressive T-cell lymphoma with a poor prognosis in advanced stages. Allogeneic hematopoietic cell transplantation (allo-HCT) offers a potential cure, but complications such as graft-versus-host disease (GvHD) remain a clinical challenge. Mogamulizumab, a humanized anti-CC chemokine receptor 4 (CCR4) antibody, is sometimes used as a bridge to transplantation, but its potential interactions with allo-HCT are unclear.

Overlapping features of hepatic complications after hematopoietic cell transplantation in a rare T-cell lymphoma: A clinical challenge.

We present the case of a young adult, who developed several hepatic post-HCT complications, which made differential diagnosis extremely difficult.

Use of Measurable Residual Disease to Evolve Transplant Policy in Acute Myeloid Leukemia: A 20-Year Monocentric Observation.

Measurable residual disease (MRD) is increasingly employed as a biomarker of quality of complete remission (CR) in intensively treated acute myeloid leukemia (AML) patients. We evaluated if a MRD-driven transplant policy improved outcome as compared to a policy solely relying on a familiar donor availability. High-risk patients (adverse karyotype, FLT3-ITD) received allogeneic hematopoietic cell transplant (alloHCT) whereas for intermediate and low risk ones (CBF-AML and NPM1-mutated), alloHCT or autologous SCT was delivered depending on the post-consolidation measurable residual disease (MRD) status, as assessed by flow cytometry.

Matched-Pair Analysis of Transplant from Haploidentical, Unmanipulated Bone Marrow Donor versus HLA Identical Sibling for Patients with Hematologic Malignancies.

A matched-pair analysis of transplant-related outcomes was carried out in 116 of 255 consecutive patients who received transplants from an HLA identical sibling (n = 58) or haploidentical related donor (n = 58). The 2 patient series were matched with 9 variables: period of transplant, patient and donor age, sex, diagnosis, disease phase, conditioning regimen, donor-recipient sex, and cytomegalovirus (CMV) status combinations. As graft-versus-host disease (GVHD) prophylaxis, all patients received the standard cyclosporine and methotrexate association with the addition of anti-thymocyte globulins, mycophenolate mofetil, and basiliximab in haploidentical, unmanipulated bone marrow recipients.

Clinical significance of occult central nervous system disease in adult acute lymphoblastic leukemia. A multicenter report from the Campus ALL Network.

In acute lymphoblastic leukemia, flow cytometry detects more accurately leukemic cells in patients' cerebrospinal fluid compared to conventional cytology. However, the clinical significance of flow cytometry positivity with a negative cytology - occult central nervous system disease - is not clear. In the framework of the national Campus ALL program, we retrospectively evaluated the incidence of occult central nervous system disease and its impact on outcome in 240 adult patients with newly diagnosed acute lymphoblastic leukemia.

Involvement of central nervous system in adult patients with acute myeloid leukemia: Incidence and impact on outcome.

Incidence and effect on outcome of central nervous system (CNS) involvement in adult patients with acute myeloid leukemia (AML) is not clearly defined. To address this issue, 103 consecutive adult patients with newly diagnosed AML, regardless of neurologic symptoms, were submitted to a routine explorative lumbar puncture. Cerebrospinal fluid (CSF) samples were collected from 65 males and 38 females.

The Rome Transplant Network model compared to the Italian Bone Marrow Donor Registry activity for unrelated donor search process and transplant efficiency for hematologic malignancy.

Background: From 2011 to 2014, a total of 71% of the 3834 patients with hematologic malignancies successfully identified a matched unrelated donor (MUD) through the Italian Bone Marrow Donor Registry (IBMDR), corresponding to a transplant efficiency of 62%.

Study Design And Methods: From 2006, the Rome Transplant Network (RTN) followed a hierarchical selection strategy for the alternative donor search: first MUD, second cord blood, and third haploidentical donor. Using a low-resolution HLA, a preliminary query (PQ) was performed in all cases with assignment of good or poor score if more or less than 10 MUDs were identified in Bone Marrow Donors Worldwide.

Ponatinib Induces a Persistent Molecular Response and Graft-versus-Host Disease/Graft-versus-Leukemia Effect in a Patient with Philadelphia-Positive Acute Lymphoblastic Leukemia with a T315I Mutation following Early Relapse after Allogeneic Transplant.

We describe the case of a patient with a Philadelphia-positive (Ph+) acute lymphoblastic leukemia (ALL) treated with dasatinib plus steroids as the first-line therapy who achieved a molecular complete remission and then underwent a matched, unrelated donor allogeneic transplant. Five months after the transplant, he experienced a disease relapse with an T315I mutation, which was resistant to salvage chemotherapy. Once the details of the T315I mutation were acquired, we initiated ponatinib treatment at a standard dosage and observed a rapid decrease of minimal residual disease (MRD) at molecular assessment.

Minimal residual disease as biomarker for optimal biologic dosing of ARA-C in patients with acute myeloid leukemia.

We assessed by flow cytometry minimal residual disease (MRD) in patients with acute myeloid leukemia (AML) given standard-dose (SDAC) and high-dose ARA-C (HDAC) regimens. Of 163 patients enrolled, 130 (median age, 45 years; range, 18-59 years) qualified for analysis, all achieving complete remission after treatment with SDAC (n = 78) or HDAC (n = 52) plus etoposide and daunorubicin. Consolidation consisted of intermediate-dose ARA-C and daunorubicin.

Fibrin glue therapy for severe hemorrhagic cystitis after allogeneic hematopoietic stem cell transplantation.

Hemorrhagic cystitis (HC) occurring after allogeneic transplantation significantly affects quality of life and, in some cases, becomes intractable, increasing the risk of death. To date, its therapy is not established. We used the hemostatic agent fibrin glue (FG) to treat 35 patients with refractory post-transplantation HC.

High sensitivity of flow cytometry improves detection of occult leptomeningeal disease in acute lymphoblastic leukemia and lymphoblastic lymphoma.

Conventional cytology (CC) of cerebrospinal fluid (CSF) fails to demonstrate malignant cells in up to 45 % of patients with acute lymphoblastic leukemia or lymphoblastic lymphoma (ALL/LL) in whom occult leptomeningeal disease is present. Flow cytometry (FCM) is considered more sensitive than CC, but clinical implications of CC negativity/CC positivity are not yet established. CSF samples from 38 adult patients with newly diagnosed ALL/LL were examined.

Tumor necrosis factor is elevated in progressive multiple sclerosis and causes excitotoxic neurodegeneration.

Background: Chronic inflammation leads to gray matter damage in progressive multiple sclerosis (MS), but the mechanism linking inflammation and neurodegeneration is unclear.

Objective: The objective of this paper is to investigate the synaptic mechanism of inflammatory neurodegeneration in progressive forms of MS.

Methods: Cytokine and neurofilament-light were determined in cerebrospinal fluid (CSF) of MS patients.

Bowel ultrasonography as an aid for diagnosis of intestinal acute graft-versus-host-disease after allogeneic haematopoietic stem cell transplantation.

Objective: Aim of our prospective study was to investigate accuracy of bowel ultrasonography in detecting gastrointestinal acute graft versus host disease (GVHD), when using clinical assessment as gold standard. In a subgroup of patients, bowel ultrasonography was compared with colonoscopy and histology in diagnosing of gastrointestinal acute GVHD.

Methods: Fifty-two patients underwent allogeneic hematopoietic stem cell transplantation and developed gastrointestinal symptoms.

Haploidentical, unmanipulated, G-CSF-primed bone marrow transplantation for patients with high-risk hematologic malignancies.

Unlabelled: Eighty patients with high-risk hematologic malignancies underwent unmanipulated, G-CSF–primed BM transplantation from an haploidentical family donor. Patients were transplanted in first or second complete remission (CR, standard-risk: n =45) or in > second CR or active disease (high-risk: n =35). The same regimen for GVHD prophylaxis was used in all cases.

Granulocyte-mobilized bone marrow.

Purpose Of Review: In the last few years, mobilized peripheral blood has overcome bone marrow as a graft source, but, despite the evidence of a more rapid engraftment, the incidence of chronic graft-versus-host disease is significantly higher with, consequently, more transplant-related mortality on the long follow-up. Overall, the posttransplant outcome of mobilized peripheral blood recipients is similar to that of patients who are bone marrow grafted. More recently, the use of bone marrow after granulocyte colony-stimulating factor (G-CSF) donor priming has been introduced in the transplant practice.

Spontaneous bilateral kidney rupture during autologous stem cell transplantation in a patient affected by amyloidosis.

Kidney spontaneous rupture is not a recognized complication neither for amyloidosis nor of autologous stem cell transplantation (ASCT). A 46-year-old white woman, affected by nephrotic syndrome, was diagnosed as AL amyloidosis by renal biopsy. We report the singular case of a bilateral spontaneous kidney rupture during ASCT for AL with renal rescue.

Platelet gel for treatment of mucocutaneous lesions related to graft-versus-host disease after allogeneic hematopoietic stem cell transplant.

Background: Platelet (PLT) gel has been successfully used in tissue regeneration of diabetic/surgical wounds through the releasing of growth factors such as basic fibroblast growth factor and PLT-derived growth factor. Therefore, the PLT gel could represent a therapeutic tool in treating the deep and painful wounds sometimes occurring during graft-versus-host disease (GVHD).

Study Design And Methods: The aim of this study was to verify the efficacy and safety of PLT gel for treating GVHD ulcers.
