Polymyalgia rheumatica and giant cell arteritis following COVID-19 vaccination: Results from a nationwide survey.

We conducted a national in-depth analysis including pharmacovigilance reports and clinical study to assess the reporting rate (RR) and to determine the clinical profile of polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) in COVID-19-vaccinated individuals. First, based on the French pharmacovigilance database, we estimated the RR of PMR and GCA cases in individuals aged over 50 who developed their initial symptoms within one month of receiving the BNT162b2 mRNA, mRNA-1273, ChAdOx1 nCoV-19, and Ad26.COV2.

Molecular B-cell clonality assay in minor salivary glands as a useful tool for the lymphoma risk assessment in Sjögren's syndrome.

Objectives: Non-Hodgkin's lymphoma (NHL) risk assessment is crucial in Sjögren's syndrome (SS). We studied the prevalence of clonal immunoglobulin gene rearrangements in minor salivary glands (MSG) and their correlations with lymphoma occurrence and with previously established NHL predictors.

Methods: Molecular B-cell expansion was studied in fresh-frozen MSG of 207 patients with either suspected SS or with suspected lymphoma during SS, using a standardised multiplex PCR assay combined with heteroduplex analysis by microcapillary electrophoresis.

Life-threatening toxicities upon Pembrolizumab intake: could pharmacokinetics be the bad guy?

Purpose: We report the case of an adult patient diagnosed with Hodgkin's lymphoma who was scheduled for Pembrolizumab after failure of standard therapy. After three well-tolerated courses of Pembrolizumab, a PET scan showed a favorable outcome and a fourth course of Pembrolizumab was started. Unexpectedly, extremely severe toxicities (i.

Peripheral blood haploidentical hematopoietic cell transplantation for patients aged 70 years and over with acute myeloid leukemia or high-risk myelodysplastic syndrome.

Haploidentical stem cell transplantation (Haplo-SCT) using non-myeloablative conditioning regimen (NMAC) has extended the feasibility of allogeneic transplantation, notably in older patients. However, there is few data specifically focusing on patients aged 70 years and over with AML and MDS. Thus the benefit of transplantation in this population is still debated.

Allogeneic stem cell transplantation in poor prognosis peripheral T-cell lymphoma: the impact of different donor type on outcome.

We report the outcome of 68 patients with advanced peripheral T-cell lymphoma receiving transplantation from haploidentical or from conventional donors. The 4-year OS, PFS, 2-year cumulative incidence of relapse and 2-year GRFS was 75%, 70%, 21%, and 51%, respectively. Survival was not affected by donor type.

Checkpoint inhibition before haploidentical transplantation with posttransplant cyclophosphamide in Hodgkin lymphoma.

We report on 59 Hodgkin lymphoma patients undergoing haploidentical stem cell transplantation (SCT; haplo-SCT) with posttransplant cyclophosphamide (PTCy) as graft-versus-host disease (GVHD) prophylaxis, comparing outcomes based on pretransplant exposure to checkpoint inhibitors (CPIs). Considering pretransplant characteristics, the 2 cohorts (CPI = 29 patients vs no-CPI = 30 patients) were similar, except for the number of prior lines of therapy (6 vs 4; P < .001).

Posttransplantation cyclophosphamide vs. antithymocyte globulin as GVHD prophylaxis for mismatched unrelated hematopoietic stem cell transplantation.

Posttransplant cyclophosphamide (PT-Cy) is an efficient GVHD prophylaxis but has not been extensively evaluated in mismatched unrelated donor (MMUD) allo-HSCT, for which antithymocyte globulin (ATG) is still considered as a standard. Thus, we evaluated the outcome of MMUD allo-HSCT with PT-Cy (n = 22) and performed a historical comparison with a control group receiving ATG (n = 40) in a single center experience. Compared with the ATG group, the risk of grade 2-4 acute GVHD was significantly lower in the PT-Cy group (HR = 0.

Thiotepa, Fludarabine, and Busulfan Conditioning Regimen before T Cell-Replete Haploidentical Transplantation with Post-Transplant Cyclophosphamide for Acute Myeloid Leukemia: A Bicentric Experience of 100 Patients.

Haploidentical stem cell transplantation (haplo-SCT) with post-transplant cyclophosphamide (PT-Cy) is an alternative treatment for acute myeloid leukemia (AML) patients who lack HLA-matched donors. Relapse after haplo-SCT remains a major concern, especially after nonmyeloablative conditioning regimens. Promising results were reported for TBF-based conditioning regimens (thiotepa, busulfan, and fludarabine) in patients transplanted from different categories of donors and for various disease types but not specifically in PT-Cy haplo-SCT for AML.

Peripheral blood stem cell for haploidentical transplantation with post-transplant high dose cyclophosphamide: detailed analysis of 181 consecutive patients.

While bone marrow (BM) grafts were initially used for T-replete HLA-haploidentical related donors transplantation (Haplo-SCT) with post-transplantation cyclophosphamide (PT-Cy), the use of peripheral blood stem cell (PBSC) remains debated. We thus conducted a detailed analysis evaluating the incidence, risk factors, and prevalence of GVHD after PBSC Haplo-SCT with PT-Cy. One hundred and eighty-one patients with hematological diseases were included.

The new refined minnesota risk score for acute graft-versus-host disease predicts overall survival and non-relapse mortality after T cell-replete haploidentical stem cell transplant with post-transplant cyclophosphamide.

We propose to test whether the new refined Minnesota risk score, which represents a new tool for acute Graft-versus-Host-Disease (aGVHD) grading, may be useful to predict the final outcome of patients with aGVHD after haploidentical stem cell transplantation (Haplo-SCT) with post-transplant cyclophosphamide (PT-Cy). Hundred consecutive patients with grade 2-4 aGVHD were included. Twenty-two percent of the patients had high-risk (HR) aGVHD and had a lower chance to respond at day 28: 41% of non-responders (NR) were in the HR vs 13% in the standard-risk (SR) group (p = 0.

Post-transplantation cyclophosphamide-based haploidentical versus Atg-based unrelated donor allogeneic stem cell transplantation for patients younger than 60 years with hematological malignancies: a single-center experience of 209 patients.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is limited by availability of HLA-matched sibling donors (MSDs). The alternative use of unrelated donors (UDs) is currently challenged by haploidentical-related donors (HRDs). We retrospectively analyzed 209 consecutive patients younger than 60 years undergoing allo-HSCT from UDs (n = 128) or HRDs (n = 81).

HLA-Matched Sibling versus Unrelated versus Haploidentical Related Donor Allogeneic Hematopoietic Stem Cell Transplantation for Patients Aged Over 60 Years with Acute Myeloid Leukemia: A Single-Center Donor Comparison.

Haploidentical related donor (HRD) allogeneic hematopoietic stem cell transplantation (allo-HSCT) was developed as a valid option for the treatment of acute myeloid leukemia (AML) in the absence of a matched donor. However, many investigators are reluctant to consider the use of this alternative in elderly patients, anticipating high morbidity. Here, we report a single-center comparison of HRD versus matched sibling donor (MSD) and unrelated donor (UD) allo-HSCT for patients with AML aged ≥60 years.

Killer Cell Immunoglobulin-Like Receptor-Ligand Mismatch in Donor versus Recipient Direction Provides Better Graft-versus-Tumor Effect in Patients with Hematologic Malignancies Undergoing Allogeneic T Cell-Replete Haploidentical Transplantation Followed by Post-Transplant Cyclophosphamide.

We evaluated the impact of unidirectional donor versus recipient killer cell immunoglobulin-like receptor (KIR)-ligand mismatch (KIR-Lmm) on the outcomes of T cell-replete haploidentical stem cell transplantation (Haplo-SCT) with post-transplant cyclophosphamide (PT-Cy) in a cohort of 144 patients treated for various hematologi diseases. We separately analyzed 81 patients in complete remission (CR group) and 63 with active disease (no CR group) at the time of Haplo-SCT. One-third of patients in each group had KIR-Lmm.

Increased serum levels of fractalkine and mobilisation of CD34CD45 endothelial progenitor cells in systemic sclerosis.

Background: The disruption of endothelial homeostasis is a major determinant in the pathogenesis of systemic sclerosis (SSc) and is reflected by soluble and cellular markers of activation, injury and repair. We aimed to provide a combined assessment of endothelial markers to delineate specific profiles associated with SSc disease and its severity.

Methods: We conducted an observational, single-centre study comprising 45 patients with SSc and 41 healthy control subjects.

The efficacy and safety of a new reduced-toxicity conditioning with 4 days of once-daily 100 mg/m(2) intravenous busulfan associated with fludarabine and antithymocyte globulins prior to allogeneic stem cell transplantation in patients with high-risk myelodysplastic syndrome or acute leukemia.

The optimal intensity of myeloablation associated with a reduced-toxicity conditioning (RTC) regimen in order to decrease the relapse rate without increasing non-relapse mortality (NRM), is not well established yet. This retrospective analysis was done on 30 patients with hematological malignancies. The aim was to assess the safety of a RTC regimen based on the busulfan at a dose of 100 mg/m(2)/d intravenously for 4 d, fludarabine at a dose of 30 mg/m(2)/d for 5 d, and anti-thymoglobulins at a dose of 2.

Haploidentical T Cell-Replete Transplantation with Post-Transplantation Cyclophosphamide for Patients in or above the Sixth Decade of Age Compared with Allogeneic Hematopoietic Stem Cell Transplantation from an Human Leukocyte Antigen-Matched Related or Unrelated Donor.

It has recently been shown that a T cell-replete allogeneic (allo) hematopoietic stem cell transplantation (HSCT) from a haploidentical donor (haplo-ID) could be a valid treatment for hematological malignancies. However, little data exist concerning older populations. We provided transplantation to 31 patients over the age of 55 years from a haplo-ID and compared their outcomes with patients of the same ages who underwent transplantation from a matched related (MRD) or an unrelated donor (UD).
