Respiratory Viruses in Patients With Hematological Malignancy in Boreal Autumn/Winter 2023-2024: EPICOVIDEHA-EPIFLUEHA Report.

Community-acquired respiratory viral infections (CARV) significantly impact patients with hematological malignancies (HM), leading to high morbidity and mortality. However, large-scale, real-world data on CARV in these patients is limited. This study analyzed data from the EPICOVIDEHA-EPIFLUEHA registry, focusing on patients with HM diagnosed with CARV during the 2023-2024 autumn-winter season.

Disseminated cerebral cryptococcosis after silent West Nile virus infection in a patient with polycythemia vera: A case report and review of the literature.

Although disseminated cryptococcosis can occur occasionally, it is most commonly seen in immunodeficient patients. In 2005, a 43-year-old man was diagnosed with polycythemia vera. Following in 2018, he experienced an unknown-cause fever and headache.

Survival in multiple myeloma and SARS-COV-2 infection through the COVID-19 pandemic: Results from the EPICOVIDEHA registry.

Patients affected by multiple myeloma (MM) have an increased risk of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infection and subsequent coronavirus (20)19 disease (COVID-19)-related death. The changing epidemiological and therapeutic scenarios suggest that there has been an improvement in severity and survival of COVID-19 during the different waves of the pandemic in the general population, but this has not been investigated yet in MM patients. Here we analyzed a large cohort of 1221 patients with MM and confirmed SARS-CoV-2 infection observed between February 2020, and August 2022, in the EPICOVIDEHA registry from 132 centers around the world.

Age, successive waves, immunization, and mortality in elderly COVID-19 hematological patients: EPICOVIDEHA findings.

Objectives: Elderly patients with hematologic malignancies face the highest risk of severe COVID-19 outcomes. The infection's impact on different age groups remains unstudied in detail.

Methods: We analyzed elderly patients (age groups: 65-70, 71-75, 76-80, and >80 years old) with hematologic malignancies included in the EPICOVIDEHA registry between January 2020 and July 2022.

Molnupiravir compared to nirmatrelvir/ritonavir for COVID-19 in high-risk patients with haematological malignancy in Europe. A matched-paired analysis from the EPICOVIDEHA registry.

Introduction: Molnupiravir and nirmatrelvir/ritonavir are antivirals used to prevent progression to severe SARS-CoV-2 infections and decrease hospitalisation and mortality rates. Nirmatrelvir/ritonavir was authorised in Europe in December 2021, whereas molnupiravir is not yet licensed in Europe as of February 2022. Molnupiravir may be an alternative to nirmatrelvir/ritonavir because it is associated with fewer drug-drug interactions and contraindications.

Nirmatrelvir/ritonavir in COVID-19 patients with haematological malignancies: a report from the EPICOVIDEHA registry.

Background: Nirmatrelvir/ritonavir treatment decreases the hospitalisation rate in immunocompetent patients with COVID-19, but data on efficacy in patients with haematological malignancy are scarce. Here, we describe the outcome of nirmatrelvir/ritonavir treatment in a large cohort of the latter patients.

Methods: This is a retrospective cohort study from the multicentre EPICOVIDEHA registry (NCT04733729) on patients with haematological malignancy, who were diagnosed with COVID-19 between January and September 2022.

Outcomes of SARS-CoV-2 infection in Ph-neg chronic myeloproliferative neoplasms: results from the EPICOVIDEHA registry.

Background: Patients with Philadelphia-negative chronic myeloproliferative neoplasms (MPN) typically incur high rates of infections and both drugs and comorbidities may modulate infection risk.

Objectives: The present study aims to assess the effect of immunosuppressive agents on clinical outcomes of MPN patients affected by the coronavirus disease 2019 (COVID-19).

Design: This is an observational study.

COVID-19 infection in adult patients with hematological malignancies: a European Hematology Association Survey (EPICOVIDEHA).

Background: Patients with hematological malignancies (HM) are at high risk of mortality from SARS-CoV-2 disease 2019 (COVID-19). A better understanding of risk factors for adverse outcomes may improve clinical management in these patients. We therefore studied baseline characteristics of HM patients developing COVID-19 and analyzed predictors of mortality.

Clinical Characteristics and Treatment Outcome of Hypocellular Acute Myeloid Leukemia Based on WHO Classification.

The hypocellular acute leukemia is very rare atypical leukemia with frequency of 5-7% among patients with acute leukemias. It mainly occurs in older patients and usually has a myeloid phenotype. It is still unclear whether the outcome of hypocellular acute myeloid leukemia is less favorable than adult acute myeloid leukemia with normal cellularity.

Investigation of a healthcare-associated Candida tropicalis candidiasis cluster in a haematology unit and a systematic review of nosocomial outbreaks.

Background: Non-albicans Candida spp. are an emerging cause of hospital-acquired bloodstream infections, associated with high mortality due to the challenges in diagnosis and delayed treatment.

Objectives: We aimed to investigate a cluster of healthcare-associated invasive candidiasis caused by C tropicalis and review the literature of healthcare-associated outbreaks or clusters caused by C tropicalis.

CD56-Positive Acute Myeloid Leukemia Following Treatment of Hairy Cell Leukemia with Cladribine - Report of 2 Cases and Review of the Literature.

Treatment of hairy cell leukemia (HCL) with alfa-interferon and purine analogs significantly prolongs survival in these patients. However, with life prolongation, an increased risk of secondary malignancies has been reported. Acute myeloid leukemia (AML), as a second malignancy after HCL treatment is extremely rare and has been reported in only 12 cases so far.

Association of Expression and Ratio with Clinical and Molecular Prognostic Markers in Chronic Lymphocytic Leukemia.

Background: In chronic lymphocytic leukemia (CLL), apoptotic resistance of malignant B lymphocytes results, in part, from the intrinsic defects of their apoptotic machinery. These include genetic alterations and aberrant expression of many apoptosis regulators, among which the family members play a central role.

Aim: The aim of this study was to investigate the association of pro-apoptotic gene expression and ratio with the clinical features of CLL patients as well as with molecular prognostic markers, namely the mutational status of rearranged immunoglobulin heavy variable (IGHV) genes and lipoprotein lipase () gene expression.

Predictive parameters for imatinib failure in patients with chronic myeloid leukemia.

Objective: Until recently, imatinib was the standard first-line treatment in chronic myeloid leukemia (CML). The inclusion of nilotinib and dasatinib as first-line options in CML raised a debate on treatment selection. The aim of our study was to analyze predictive parameters for imatinib response as the first-line treatment of CML patients.

Somatic mutations of isocitrate dehydrogenases 1 and 2 are prognostic and follow-up markers in patients with acute myeloid leukaemia with normal karyotype.

Background: Mutations in the isocitrate dehydrogenase 1 and 2 ( and ) genes are frequent molecular lesions in acute myeloid leukaemia with normal karyotype (AML-NK). The effects of mutations on clinical features and treatment outcome in AML-NK have been widely investigated, but only a few studies monitored these mutations during follow-up.

Patients And Methods: In our study samples from 110 adult AML-NK were studied for the presence of and mutations, their associations with other prognostic markers and disease outcome.

Mucormycosis of the paranasal sinuses in a patient with acute myeloid leukemia.

Introduction: Invasive fungal infection is among the leading causes of morbidity, mortality, and economic burden for patients with acute leukemia after induction of chemotherapy. In the past few decades, the incidence of invasive fungal infection has increased dramatically. Its management has been further complicated by the increasing frequency of infection by non-Aspergillus molds (e.

[Treatment by bloodletting in the past and present].

Introduction: Therapeutic bloodletting has been practiced at least 3000 years as one of the most frequent methods of treatment in general, whose value was not questioned until the 19th century, when it was gradually abandoned in Western medicine, while it is still practiced in Arabic and traditional Chinese medicine.

Content: In modern medicine bloodletting is practiced for very few indications. Its concept was modeled on the process of menstrual bleeding, for which it was believed to"purge women of bad humours.

Hypercalcemia with multiple osteolytic lesions and increased circulating tumor necrosis factor in an adult patient with B-cell acute lymphoblastic leukemia.

Introduction: Acute lymphoblastic leukemia (ALL) is very rarely presented with diffuse osteolytic lesions and hypercalcemia.

Case Outline: We report a 28-year-old male with the B-cell ALL who presented with extensive osteolytic lesions, bone pain, hepatosplenomegaly, and pancytopenia without circulating blasts in peripheral blood. An increased serum level of tumor necrosis factor (TNF-α) was registered while the levels of IL-1α and IL-1β were normal.

Peripartum cardiomyopathy in a patient treated for acute myeloid leukemia.

Introduction: Peripartum cardiomyopathy usually presents with systolic heart failure during the last months of pregnancy and up to five months postpartum. The disease is rare and can be fatal.

Case Outline: We report a 30-year-old female who was diagnosed with acute myeloid leukemia, with maturation and cytogenetic finding of t(8;21)(q22;q22),del(9)(q22) in January 2004.

Decreased CD161 activating and increased CD158a inhibitory receptor expression on NK cells underlies impaired NK cell cytotoxicity in patients with multiple myeloma.

Aim: As innate immune cells natural killer (NK), NK-like T and CTLγδ are important in antitumour response in multiple myeloma (MM), the aim of this study was to investigate some functional and phenotypical characteristics of these cells in MM.

Methods: 29 patients with MM prior to therapy, in clinical stage I-III and 15 healthy controls (HCs) were investigated. Percent of immune cells in peripheral blood, NK cell activity, expression of activating (CD161) and inhibitory (CD158a, CD158b) NK cell receptors on CD3CD16 NK cells were evaluated using 51-chromium-release assay and by flow cytometry.
