Oral iptacopan monotherapy in paroxysmal nocturnal haemoglobinuria: final 48-week results from the open-label, randomised, phase 3 APPLY-PNH trial in anti-C5-treated patients and the open-label, single-arm, phase 3 APPOINT-PNH trial in patients previously untreated with complement inhibitors.

Background: The factor B inhibitor iptacopan improved 24-week outcomes in adult patients with paroxysmal nocturnal haemoglobinuria in the phase 3 APPLY-PNH and APPOINT-PNH trials; the trial extension periods assessed clinical activity and safety up to 48 weeks. Here, we report the final 48-week data from APPLY-PNH and APPOINT-PNH.

Methods: In both APPLY-PNH and APPOINT-PNH trials, patients were aged 18 years or older, with paroxysmal nocturnal haemoglobinuria (red and white blood cell population sizes ≥10%) and without laboratory evidence of bone marrow failure.

Demographics, clinical characteristics, and real-world treatment patterns among patients with beta-thalassemia: a retrospective medical record abstraction study.

Background: Beta-thalassemias (BTs) are characterized by deficient or absent synthesis of the beta-globin subunit, leading to anemia. Patient characteristics and treatment patterns in these patients may vary.

Objective: This retrospective study evaluated demographics, clinical characteristics, and treatment patterns in patients with transfusion-dependent BT (TDT) and non-transfusion-dependent BT (NTDT).

[Transition in sickle cell disease - recommendations of the transition initiative sickle cell disease].

Sickle cell disease is a rare, but complex multi-systemic disorder with high need of interdisciplinary and specialized care and new structural requirements. Besides care of those chronically sick patients, transition process is a vulnerable phase which highly influences further treatment. To make matters worse, patients often have migration background with subsequent communication problems.

Long-term outcomes of patients with paroxysmal nocturnal hemoglobinuria treated with eculizumab in a real-world setting.

Objective: Describe the real-world clinical profile of eculizumab-treated patients by characterizing their short- and long-term clinical and laboratory outcomes.

Methods: This retrospective study used preexisting medical records of eculizumab-treated patients with paroxysmal nocturnal hemoglobinuria (PNH) at the University Hospital Essen. Hematologic response, breakthrough hemolysis, transfusion dependence, and other outcomes were assessed.

Luspatercept, a two-edged sword in beta-thalassemia-associated paravertebral extramedullary hematopoietic masses (EHMs).

Paravertebral extramedullary hematopoietic masses (EHMs) account for up to 15% of extramedullary pseudotumors in beta-thalassemia (BT) and are most likely related to compensatory hematopoiesis. In most cases, pseudotumors are incidentally detected, as the majority of patients are asymptomatic. Since June 2020, luspatercept is approved for the treatment of patients with BT who require regular red blood cell transfusions.

Transition in Sickle Cell Disease (SCD): A German Consensus Recommendation.

Sickle cell disease (SCD) is considered a rare disease in Germany. Due to the increasing prevalence, the acute and chronic morbidities associated with the disease and the sharp increase in the mortality rate of young adults, a need-based transition structure for patients with SCD in Germany is explicitly required. This is the first multicenter German consensus statement addressing the importance of implementing a standardized transition guideline that allows adolescents and young adults to safely transition from pediatric to adult care.

Early report on the severity of COVID-19 in hematologic patients infected with the SARS-CoV2 omicron variant.

Introduction: Patients with hematologic disease are at high risk of morbidity and mortality from COVID-19 due to disease-inherent and therapy-related immunodeficiency. Whether infection with the SARS-CoV2 omicron variant leads to attenuated disease severity in these patients is currently unknown.

Methods: We assessed clinical and laboratory parameters in 61 patients with underlying hematologic conditions with a SARS-CoV2 omicron variant infection confirmed by nucleic acid amplification testing.

Screening and diagnosis of hemoglobinopathies in Germany: Current state and future perspectives.

This monocentric study conducted at the Pediatric and Adult Hemoglobinopathy Outpatient Units of the University Hospital of Essen summarizes the results of hemoglobinopathies diagnosed between August 2018 and September 2021, prior to the introduction of a general newborn screening (NBS) for SCD in Germany (October 2021). In total, 339 patients (pts.), 182 pediatric [50.

Acquired aplastic anemia following SARS-CoV-2 vaccination.

COVID-19 is a potential life-threatening viral disease caused by SARS-CoV-2 and was declared a pandemic by the WHO in March 2020. mRNA-based SARS-CoV-2 vaccines are routinely recommended in immune-compromised patients, including patients with AA, as these patients are at increased risk of contracting COVID-19 and developing a more severe course of disease. Between March 2021 and November 2021 relapse of AA occurred in four (age [median]: 53 years, range 30-84 years) out of 135 patients currently registered at our department and two de novo cases of AA in temporal context to vaccination against SARS-CoV-2, were documented.

Impact of CMV reactivation on relapse of acute myeloid leukemia after HCT is dependent on disease stage and ATG.

Cytomegalovirus (CMV) reactivation is a frequent complication after allogeneic hematopoietic cell transplantation (HCT), whose impact on clinical outcome, in particular on leukemic relapse, is controversial. We retrospectively analyzed 687 HCT recipients with acute myeloid leukemia (AML) and ciclosporin-based immunosuppression to better understand the differential impact of CMV on transplant outcomes depending on AML disease stage and in vivo T cell depletion with antithymocyte globulin (ATG). Without ATG, CMV reactivation associated with significantly reduced relapse, yet its effect was more pronounced for advanced disease AML (P = .

Pregnancies and Neonatal Outcomes in Patients with Sickle Cell Disease (SCD): Still a (High-)Risk Constellation?

Background: This monocentric study conducted at the University Hospital of Essen aims to describe maternal and fetal/neonatal outcomes in sickle cell disease (SCD) documented between 1996 to 2021 (N = 53), reflecting the largest monocentric analysis carried out in Germany.

Methods/results: 46 pregnancies in 22 patients were followed. None of the patients died.

Pregnancy in Classical Paroxysmal Nocturnal Hemoglobinuria and Aplastic Anemia-Paroxysmal Nocturnal Hemoglobinuria: A High-Risk Constellation.

Pregnancies in paroxysmal nocturnal hemoglobinuria (PNH) are associated with increased morbidity and mortality. Retrospective studies suggest that outcome has improved with the advent of the complement inhibitor eculizumab. To substantiate this assumption we analyzed the data from patients treated in our department since 2009.

Veno-Venous Extracorporeal Membrane Oxygenation in Adult Patients with Sickle Cell Disease and Acute Chest Syndrome: a Single-Center Experience.

Acute chest syndrome (ACS) in adult patients with sickle cell disease represents a leading cause of death. It is characterized by a new density on chest X-ray accompanied by fever and/or respiratory symptoms. Currently, 49 adult patients with sickle cell disease are registered at our department.

No evidence for hypogammaglobulinemia in patients with paroxysmal nocturnal hemoglobinuria (PNH) chronically treated with ravulizumab.

Introduction: Ravulizumab (ALXN1210) is a long-lasting recycling IgG monoclonal antibody with an increased affinity for the neonatal Fc receptor (FcRn). The FcRn is essential for regulating IgG homeostasis. Saturation of the FcRn pathway is seen under high IgG doses as they compete with endogenous IgG to bind the FcRn by their Fc regions, resulting in enhanced IgG clearance.

Improved survival in metastatic breast cancer: results from a 20-year study involving 1033 women treated at a single comprehensive cancer center.

Purpose: Diagnosis and treatment of breast cancer have changed profoundly over the past 25 years. The outcome improved dramatically and was well quantified for early stage breast cancer (EBC). However, progress in the treatment of metastatic disease has been less convincingly demonstrated.

Baseline and interim PET-based outcome prediction in peripheral T-cell lymphoma: A subgroup analysis of the PETAL trial.

The prospective randomized Positron Emission Tomography (PET)-Guided Therapy of Aggressive Non-Hodgkin Lymphomas (PETAL) trial was designed to test the ability of interim PET (iPET) to direct therapy. As reported previously, outcome remained unaffected by iPET-based treatment changes. In this subgroup analysis, we studied the prognostic value of baseline total metabolic tumor volume (TMTV) and iPET response in 76 patients with T-cell lymphoma.

Serologic response to meningococcal vaccination in patients with cold agglutinin disease (CAD) in the novel era of complement inhibition.

Cold agglutinin disease (CAD) is a rare, potentially life-threatening acquired autoimmune hemolytic anemia characterized by hemagglutination and hemolysis due to immunoglobulin-mediated (usually IgMκ) classic complement pathway activation. Complement inhibition (CI) represents a novel treatment option to control hemolysis. Due to CI patients (pts) are susceptible to encapsulated bacteria e.

Immunosuppressive therapy (IST) in adult patients with acquired aplastic anemia (AA): A single-center experience over the past 15 years.

Objective: Immunosuppressive therapy (IST) with horse anti-thymocyte globulin (hATG) and cyclosporine (CsA) is considered one of the first-line therapies in patients (pts) with acquired aplastic anemia (AA).

Methods: In our single-center, retrospective analysis response rates (RRs) to ATG/CsA at a minimum of 6 mo were evaluated in 67 treatment-naïve (TN) AA pts (52.2% (35/67) females; median age 45 y (range 18-89 y)) being treated at the West German Cancer Center at the Department of Hematology at the University Hospital of Essen between April 2000 and December 2015.

Six versus eight doses of rituximab in patients with aggressive B cell lymphoma receiving six cycles of CHOP: results from the "Positron Emission Tomography-Guided Therapy of Aggressive Non-Hodgkin Lymphomas" (PETAL) trial.

Standard first-line treatment of aggressive B cell lymphoma comprises six or eight cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) plus eight doses of rituximab (R). Whether adding two doses of rituximab to six cycles of R-CHOP is of therapeutic benefit has not been systematically investigated. The Positron Emission Tomography-Guided Therapy of Aggressive Non-Hodgkin Lymphomas (PETAL) trial investigated the ability of [F]-fluorodesoxyglucose PET scanning to guide treatment in aggressive non-Hodgkin lymphomas.

Correction to: Platelet number and graft function predict intensive care survival in allogeneic stem cell transplantation patients.

The author name Philipp Wohlfarth was incorrectly spelled as Philipp Wohlfahrth in the original version of this article.

Platelet number and graft function predict intensive care survival in allogeneic stem cell transplantation patients.

Despite significant advances in the treatment of complications requiring intensive care unit (ICU) admission, ICU mortality remains high for patients after allogeneic stem cell transplantation. We evaluated the role of thrombocytopenia and poor graft function in allogeneic stem cell recipients receiving ICU treatments along with established prognostic ICU markers in order to identify patients at risk for severe complications. At ICU admission, clinical and laboratory data of 108 allogeneic stem cell transplanted ICU patients were collected and retrospectively analyzed.

The Role of Whole-Body Magnetic Resonance Imaging (WB-MRI) in Patients with Paroxysmal Nocturnal Hemoglobinuria (PNH).

In PNH thromboembolic events (TEs) represent the leading cause of morbidity and mortality. Between Dec 2013 and Jan 2016 37 PNH patients (pts) (23 PNH, 14 AA/PNH; 51% (19/37) females; median age 44 years, median D-dimer levels 0.22 mg/l) were examined with a whole-body magnetic resonance imaging (WB-MRI) scan at 1.

Persisting hyperbilirubinemia in patients with paroxysmal nocturnal hemoglobinuria (PNH) chronically treated with eculizumab: The role of hepatocanalicular transporter variants.

Background: Eculizumab-treated paroxysmal nocturnal hemoglobinuria (PNH) patients (pts) show a dramatic decrease in serum lactate dehydrogenase (LDH) activities and bilirubin concentrations. However, some pts remain hyperbilirubinemic, possibly indicating an inadequate response due to extravascular hemolysis.

Methods: Mutation analyses of hepatocanalicular transporter/nuclear receptor variants (ABCB4, ABCB11, ATP8B1, NR1H4) were performed in eight (five of eight males; mean age 38 years [range 26-68 years]) out of the 174 pts with PNH/-clone at our department due to a persistent increase in total bilirubin concentrations (median 3.
