Article Synopsis
  • The COVID-19 pandemic has severely affected individuals with hematological malignancies due to their weakened immune systems, resulting in higher mortality rates and severe outcomes.
  • Data from the EPICOVIDEHA registry, which compiles COVID-19 cases from these patients worldwide, was collected from 2020 to 2022, including 8,767 cases from 152 centers across 41 countries.
  • Findings show a significant drop in critical infections and overall mortality rates, but hospitalization (especially in ICU) remains a serious risk factor; vaccination is linked to better survival outcomes, highlighting the need for ongoing monitoring and support for these patients.

Chronic myeloid leukemia is a myeloproliferative neoplasm characterized by the presence of the Philadelphia chromosome and the consequent BCR::ABL1 oncoprotein. In the era before the introduction of tyrosine kinase inhibitors (TKIs), the only potentially curative treatment was allogeneic hematopoietic stem cell transplantation (HSCT). Here, we present the case of a patient affected by CML who experienced a relapse 20 years after allogeneic HSCT.

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.

Since the beginning of the COVID-19 pandemic, there has been an overall improvement in patient mortality. However, haematological malignancy patients continue to experience significant impacts from COVID-19, including high rates of hospitalization, intensive care unit (ICU) admissions, and mortality. In comparison to other haematological malignancy patients, individuals with chronic myeloid leukemia (CML) generally have better prognosis.

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.

Article Synopsis
  • The study investigates the risk of disease progression to accelerated/blast phase (AP/BP) in patients with chronic myeloid leukemia (CML) after stopping treatment, addressing concerns raised by recent case reports.
  • A total of 870 patients were analyzed, with 505 in the treatment discontinuation (TD) cohort and 365 in a reference cohort, and the primary focus was on the time-adjusted rate (TAR) of progression and molecular relapse.
  • Findings showed that progression to AP/BP was extremely rare in the TD cohort, with no significant difference in TAR between the cohorts, suggesting that the risk of disease progression after stopping treatment should not be a major concern.

Introduction: COVID-19 pandemic had a considerable impact among haematological patients. On the other hand, the effect of this disease on patients (pts) affected by Chronic Myeloid Leukemia (CML) is not clearly defined.

Objectives: The primary objective of this study was to evaluate mortality-hospitalization rates and possible protective factors for hospitalization in CML pts affected by COVID.

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.

Article Synopsis
  • * 326 patients were analyzed, showing that COVID-19 severity ranged from mild to critical, with 21% of patients experiencing mild cases and an overall mortality rate of 21%.
  • * Key risk factors for higher mortality included being over 50 years old, having multiple comorbidities, active hematologic disease, and experiencing COVID-19 within a year of transplantation.

Background: The outcome of patients with simultaneous diagnosis of haematological malignancies (HM) and COVID-19 is unknown and there are no specific treatment guidelines. Methods: We describe the clinical features and outcome of a cohort of 450 patients with simultaneous diagnosis of HM and COVID-19 registered in the EPICOVIDEHA registry between March 2020 to February 2022. Results: Acute leukaemia and lymphoma were the most frequent HM (35.

Article Synopsis
  • * The study noted that only 16.2% of the patients were vaccinated with two or more doses prior to COVID-19 diagnosis, and vaccination status was linked to lower mortality rates.
  • * Key risk factors for increased mortality included older age, active malignancy, severe COVID-19 symptoms, and ICU admission, with additional findings showing no significant difference in survival rates between NHL and CLL patients.

Introduction: The Coronavirus disease 2019 (COVID-19) pandemic and the resulting social distancing, determined a reduction in access to care and limitations of individual freedom, with a consequent strong impact on quality of life (QoL), anxiety levels and medical management of onco-hematological people. In particular, in the case of patients with chronic myeloproliferative neoplasm (MPN), concern about SARS-CoV-2 infection added to the burden of symptoms (BS) which already weights on the QoL of these patients. We designed a cross-sectional survey in order to investigate the impact of the COVID-19 pandemic on status of anxiety, BS and QoL in MPN patients.
