RESUMO
Immunotherapy (IT) is a major therapeutic strategy for lymphoma, significantly improving patient prognosis. IT remains ineffective for a significant number of patients, however, and exposes them to specific toxicities. The identification predictive factors around efficacy and toxicity would allow better targeting of patients with a higher ratio of benefit to risk. PRONOSTIM is a multicenter and retrospective study using the Clinical Data Warehouse (CDW) of the Greater Paris University Hospitals network. Adult patients with Hodgkin lymphoma or diffuse large-cell B lymphoma treated with immune checkpoint inhibitors or CAR T (Chimeric antigen receptor T) cells between 2017 and 2022 were included. Analysis of covariates influencing progression-free survival (PFS) or the occurrence of grade ≥3 toxicity was performed. In total, 249 patients were included. From this study, already known predictors for response or toxicity of CAR T cells such as age, elevated lactate dehydrogenase, and elevated C-Reactive Protein at the time of infusion were confirmed. In addition, male gender, low hemoglobin, and hypo- or hyperkalemia were demonstrated to be potential predictive factors for progression after CAR T cell therapy. These findings prove the attractiveness of CDW in generating real-world data, and show its essential contribution to identifying new predictors for decision support before starting IT.
RESUMO
BACKGROUND: Patients with hematological malignancies are at greater risk of severe COVID-19 and have been prioritized for COVID-19 vaccination. A significant proportion of them have an impaired vaccine response, both due to the underlying disease and to the treatments. METHODS: We conducted a prospective observational study to identify the specific risks of the outpatient population with hematological diseases. RESULT: Between 22 December 2021 to 12 February 2022, we followed 338 patients of which 16.9% (n = 57) developed SARS-CoV-2 infection despite previous vaccination (94.7%). COVID-19 patients were more likely to have received immunotherapy (85.5% vs. 41%, p < 10-4), and particularly anti-CD20 monoclonal antibodies (40% vs. 14.9%, p < 10-4) and Bruton's tyrosine kinase inhibitors (BTKi) (7.3% vs. 0.7%, p < 10-2). There was no significant difference in demographic characteristics or hematological malignancies between COVID-19-positive and non-positive patients. Patients hospitalized for COVID-19 had more frequently received immunotherapy than patients with asymptomatic or benign forms (100% vs. 77.3%, p < 0.05). Hospitalized COVID-19 patients had a higher proportion of negative or weakly positive serologies than non-hospitalized patients (92.3% vs. 61%, p < 0.05). Patients who received tixagevimab/cilgavimab prophylaxis (n = 102) were less likely to be COVID-19-positive (4.9 vs. 22%, p < 0.05) without significant difference in hospitalization rates. CONCLUSION: In the immunocompromised population of patients with hematological malignancies, the underlying treatment of blood cancer by immunotherapy appears to be a risk factor for SARS-CoV-2 infection and for developing a severe form.

BACKGROUND: Given the rapidly evolving pandemic of COVID-19 in 2020, authorities focused on the repurposing of available drugs to develop timely and cost-effective therapeutic strategies. Evidence suggested the potential utility of remdesivir in the framework of an early access program. REMDECO-19 is a multicenter national cohort study assessing the ability of remdesivir to improve the outcome of patients hospitalized with COVID-19. METHODS: We conducted a retrospective real-life study that included all patients from the early access program of remdesivir in France. The primary endpoint was the clinical course evolution of critically ill and hospitalized COVID-19 patients treated with remdesivir. Secondary endpoints were the SOFA score evolution within 29 days following the admission and mortality at 29 and 90 days. RESULTS: Eighty-five patients were enrolled in 22 sites from January to April 2020. The median WHO and SOFA scores were respectively reduced by two and six points between days 1 and 29. Improvement in the WHO-CPS and the SOFA score were observed in 83.5% and 79.3% of patients, respectively, from day 10. However, there was no effect of remdesivir on the 90-day survival based on the control cohort for hospitalized COVID-19 patients with invasive ventilation. CONCLUSIONS: SOFA score appeared to be an attractive approach to assess remdesivir efficacy and stratify its utilization or not in critically ill patients with COVID-19. This study brings a new clinical benchmark for therapeutic decision making and supports the use of remdesivir for some hospitalized COVID-19 patients.
RESUMO
OBJECTIVE: The clinical benefit of pharmaceutical cares in improving the quality-of-care outcomes is well demonstrated. Clinical pharmacy services are not systematically deployed in cancer units in the absence of economic data. The aim of this prospective, observational 1-year study was to evaluate the clinical, economic and organisational impacts of pharmaceutical care into a multidisciplinary day hospital for patients treated with oral cancer drugs. METHODS: All pharmacists' interventions (PI) were documented and their impact and the probability of adverse drug events were assessed using the clinical, economic and organisational tool. RESULTS: Among 360 admissions, an average of 1.81 PI per admission was accepted. Among 452 PI leading to a clinical benefit on the patient, 16.9% had a major impact, and 1.9% had an impact on survival. The large majority of PIs (87%) increased the quality-of-care organisation. The budget impact model showed a total cost savings and cost avoidance of 539,047 per year and a cost-benefit ratio of 7.07:1. The direct cost-benefit was 201,741, and the cost avoidance was 337,306. CONCLUSION: Multidisciplinary care and pharmaceutical care are key elements to improve cancer patients' outcomes and avoid evitable healthcare costs.
