ABSTRACT
Background: Patients with lymphoproliferatie diseases (LPD) appear particularly ulnerable to SARS-CoV-2 infection, partly because of the effects of the anti-neoplastic regimens (chemotherapy, signaling pathway inhibitors, and monoclonal antibodies) on the immune system. The real impact of COVID-19 on the life expectancy of patients with different subtypes of lymphoma and targeted treatment is still unknown. Aims: The aim of this study is to describe and analyse the outcome of COVID-19 patients with underlying LPD treated with targeted drugs such as monoclonal antibodies (obinutuzumab, ofatumumab, brentuximab, niolumab or pembrolizumab), BTK inhibitors (ibrutinib, acalabrutinib), PI3K inhibitors (idelalisib), BCL2 inhibitors (enetoclax) and IMIDs, (lenalidomide). Methods: The surey was supported by EPICOVIDEHA registry. Adult patients with baseline CLL or non-Hodgkin Lymphoma (NHL) treated with targeted drugs and laboratory-confirmed COVID-19 diagnosed between January 2020 and January 2022 were selected. Results: The study included 368 patients (CLL n=205, 55.7%;NHL n=163, 44.3%) treated with targeted drugs (Table 1). Median follow-up was 70.5 days (range 19-159). Most used targeted drugs were ITKs (51.1%), anti-CD20 other than rituximab (16%), BCL2 inhibitors (7.3%) and lenalidomide (7.9%). Of note, only 16.0% of the patients were accinated with 2 or more doses of accine at the onset of COVID-19. Pulmonary symptoms were present at diagnosis in 244 patients (66.2%). Seere COVID-19 was obsered in 47.8 % patients while 21.7% were admitted to to intensie care unit (ICU), being 55 (26.8%) CLL patients and 25 (15.3%) NHL patients. More comorbidities were reported in patients with seere-critical COVID-19 compared to those with mild- asymptomatic infection (p=0.002). This difference was releant in patients with chronic heart diseases (p=0.005). Oerall, 134 patients (36.4%) died. Primary cause of death was COVID-19 in 92 patients (68.7%), LPD in 14 patients (10.4%), and a combination of both in 28 patients (20.9%).Mortality was 24.2% (89/368) at day 30 and 34.5%(127/368) at day 200. After a Cox multiariable regression age >75 years (p<0.001, HR 1.030), actie malignancy (p=0.011, HR 1.574) and admission to ICU (p<0.00, HR 4.624) were obsered as risk factors. Surial in patients admitted to ICU was 33.7% (LLC 38.1%, NHL 24%). Mortality rate decreased depending on accination status, being 34.2% in not accinated patients, 15.9-18% with one or two doses, decreasing to 9.7% in patients with booster dose (p<0.001). There was no difference in OS in NLH s CLL patients (p=0.344), nor in ITKs s no ITKs treated patients (p=0.987). Additionally, mortality rate dropped from the first semester 2020 (41.3%) to last semester 2021 (25%). Summary/Conclusion: - Our results confirm that patients with B--mallignancies treatted with targeted drugs hae a high risk off seere infection (47.8%) and mortality (36.4%) from COVID-19. - Pressence of comorbidities,, especially heart disease,, is a risk factor for seere COVIID--19 infection in ourr series. - Age >75 years,, actie mallignancy att COVIID--19 onset and ICU admission were mortality risk factors. - COVIID--19 acination was a protectie factor for mortality,, een iin this popullation wiitth humorall immunity impairment. - The learning cure in the management of the infection throughout the pandemiic and the deelopmentt off COVIID--19 treatments showed benefit in this partticullarlly ullnerablle popullation?

ABSTRACT
BACKGROUND: The COVID-19 pandemic has created enormous challenges for the clinical management of patients with hematological malignancies (HMs), raising questions about the optimal care of this patient group. METHODS: This consensus manuscript aims at discussing clinical evidence and providing expert advice on statements related to the management of HMs in the COVID-19 pandemic. For this purpose, an international consortium was established including a steering committee, which prepared six working packages addressing significant clinical questions from the COVID-19 diagnosis, treatment, and mitigation strategies to specific HMs management in the pandemic. During a virtual consensus meeting, including global experts and lead by the European Society for Medical Oncology and the European Hematology Association, statements were discussed and voted upon. When a consensus could not be reached, the panel revised statements to develop consensual clinical guidance. RESULTS AND CONCLUSION: The expert panel agreed on 33 statements, reflecting a consensus, which will guide clinical decision making for patients with hematological neoplasms during the COVID-19 pandemic.

Introduction: Patients with lymphoma and chronic lymphocytic leukemia (CLL) share immune-deficiencies due to the biological features of these diseases per se and to their treatments. They are at risk to develop severe and/or prolonged forms of Covid-19. The efficacy of vaccination against COVID in lymphoma/CLL patients also raises specific concerns: Antibody response to mRNA COVID-19 vaccine was shown to be negatively affected by CLL stage and its treatments, especially in case of previous administration of anti-CD20 antibodies (Herishanu et al). Therefore, the addition of a third dose of vaccine in immunosuppressed patients is currently recommended in France. Methods: To analyse the determinants of the antibody response after anti-SARS-Cov2 mRNA vaccines (Pfizer or Moderna), we conducted a retrospective monocentric study among adults with a past or current lymphoma/CLL who underwent serology 2 weeks or more after 2 or 3 previous injections. The decision of a third dose was at the discretion of each physician. Data were extracted from the patients' medical charts on their demographics, lymphoma history and detailed treatments, vaccinations and biological parameters (immunoglobulin (Ig) G dosage, lymphocytic, B-cell and T-cell counts) and serology (Elecsys ® Anti-SARS-CoV-2 S). Statistical tests were two-tailed and p-values < 0.05 were considered significant. Multivariable analysis was conducted using independent variables having univariate significance below 0.1. This study was conducted in accordance with the Declaration of Helsinki, and approved by the ethics committee of our institution. Results: Ninety-one patients with non-Hodgkin's lymphomas (NHL) (n=48), CLL (32) or Hodgkin's lymphoma (11) were enrolled. With a median interval since last dose of 47 days (range 15-125), 48 patients (53%) had a negative serology (Table). Gender and age were not associated with antibody response. The proportion of seronegativity was 57% among patients with B-cell NHL, and 41% among those with CLL. Among the biological variables reflecting immune deficiency, lymphocytopenia (<1.5G/L), low B-cell counts (<0.2G/L) and IgG levels (<6g/L) were significantly associated with a higher risk of seronegativity with odds-ratios (OR, [95% confidence interval]) of 5.1 [1.8-15.3], p<7x10 -4, 15.0 [3.0-147.9], p<7x10 -5, and 15.3 [3.7-93.0], p<9x10 ⁻6 respectively). Patients under watch and wait attitude and those who did not have a lymphoma/CLL treatment since at least 12 months before vaccination had a much lower risk of negative serology (OR: 0.08 [<0.01;0.4], p< 2.10 -4). Among lymphoma/CLL therapies, chemotherapy overall or targeted therapy with BTK inhibitors or Venetoclax were not significantly associated with a lower risk of negative serology. In contrast, the administration of anti-CD20 therapy during the year before first dose of vaccine was associated with a higher risk of negative serology (OR: 4.5 [1.7;12.1], p<8.10 -4). Of note, this treatment was also significantly associated with both lymphocytopenia and low B-cell counts. There was no association between the number of vaccine doses and the risk of negative serology, 59% of the patients who received 3 doses remained seronegative.A multivariable analysis associating IgG level and treatment history showed that negative serology is significantly associated with a low level of IgG (OR: 25.74 [5.58;201.14], p < 10 -3) and anti-CD20 treatment (OR: 28.70 [4.14, 382.60], p = 3x10 -3). Conclusion: Overall, previous anti-CD20 therapy and low IgG levels are the main independent factors associated with a lack of serological response after anti-SARS-Cov2 mRNA vaccine. Administration of a third vaccine does not overcome their pejorative impact. This should contribute to the elaboration of guidelines for the management of lymphoma/CLL patients during the Covid-19 era. In particular, in all non-critical clinical situation, SARS-CoV-2 vaccination should be proposed before the onset of lymphoma/CLL therapy. Meanwhile, individuals with CLL/lymphoma should receive the Covid-19 vaccine, be in ormed that they are unlikely to be protected and continue social distancing and adhere to other proven mitigation strategies. Systematic vaccination of their proxies and hospital workers should also benefit directly to patients.

ABSTRACT
With regard to the hospital drug supply chain, the safest system is the individual automated drug dispensing one provided by the pharmacy. For several years we have been trying to convince hospital decision-makers to set it up. In the meantime, to mitigate the risks of medication errors incurred by patients and caregivers, we have set up several work teams within the care units. These teams, made up of one pharmacist and one or two hospital pharmacy technicians, who notably manage the medicine cabinets in care units. The close collaboration with doctors and nurses developed over the years was a determining factor when it became necessary to provide the newly created additional intensive care units with drugs and medical devices (MDs) in order to cope with the crisis triggered by the SARS-CoV-2 epidemic. Daily monitoring of the drugs consumed by each patient, particularly neuromuscular blocking agents and MDs was a key element in managing stocks and anticipating changes of drugs, packaging and/or devices references. These facts give weight to the Claris report published in France which recognizes that the interactions of pharmacy technicians and pharmacists in the care units have positive effects in terms of quality and safety of patient care. They highlight the dangers to which patients and caregivers are exposed on Saturdays, Sundays and holidays when the pharmacy is closed. They legitimize the question of extending the opening of the pharmacy with a full team 365 days a year.
