Though some degree of development towards a better understanding of PC competencies and the "early integration" approach could be demonstrated, the adoption of the WHO recommendation alone did not suffice to integrate PC into routine cancer care early in the course of the illness. Therefore, the development of disease specific guidelines is advocated by our working group.
Surrogate measures (symptom burden, performance status) indicate that PC was integrated earlier in the course of the disease after a 1-year phase of "getting started" with EI. Yet, the WHO recommendation alone was too vague to successfully trigger EI of PC. Therefore, the authors advocate the provision of disease specific guidelines to institutionalize EI of PC. Such guidelines have been developed for 19 different malignancies and are presented separately.
Background: To comply with the World Health Organization (WHO) recommendations, our institution’s administrative directives were adopted to advocate the provision of palliative care (PC) early in the disease trajectory of breast cancer (BC). To assess the outcome of this recommendation, this study evaluated the effects of this approach. Methods: A retrospective systematic chart analysis of a 2year period was performed. The first PC consultation of patients was analyzed according to (a) physical condition, (b) symptom burden of the patients, and (c) reasons for PC consultation. Results: Many patients were already in a reduced physical state and experienced burdening symptoms when first counselled by PC. After a 1year experience with PC consultations, the number of burdening symptoms identified at first PC consultation decreased and senologists increasingly requested PC support also for nonsomatic issues. Conclusions: A development towards a better understanding of PC competencies after a 1year initiation period could be demonstrated, but BC patients continued to be in late stages of the disease at the time of first PC contact. Diseasespecific guidelines may facilitate and optimize the integration of PC into breast cancer therapy.
Objectives
Patients with inflammatory rheumatic diseases (IRD) treated with the monoclonal anti-CD20 antibody rituximab (RTX) have been identified as high-risk for severe COVID-19 outcomes. Additionally, there is increased risk due to reduced humoral immune response, induced by therapeutic B cell depletion. This study sought to quantify humoral response after vaccination against SARS-CoV-2 in patients with IRD treated with RTX. It also sought to elucidate the influence of timeframe between the last RTX dose and the first vaccination or the status of B cell depletion on antibody titre.
Methods
In this case-control study patients with IRDs previously treated with RTX were examined for humoral immune response after completing the first series of vaccinations with approved vaccines (BNT162b2 (Biontech/Pfizer), RNA-1273 (Moderna), (AstraZeneca/Oxford), Ad26.COV2.S (Janssen/Johnson & Johnson). Antibody levels were quantified using the Euroimmun Anti-SARS-CoV-2 QuantiVac ELISA [EI-S1-IgG-quant]. Blood samples were taken just before the next infusion with RTX after the vaccination. The interval between the last RTX infusion and the first vaccination against SARS-CoV-2 and other possible influencing factors on the antibody levels were evaluated.
Results
102 patients were included. 65 (64%) showed a negative antibody level (<24IE/ml) after the vaccination. The comparative univariate analysis of the antibody levels achieved a significant result (p= 0.0008) for the time between last RTX infusion and first vaccination against SARS-CoV-2. No CD19+ peripheral B-cells could be measured in 73 of the patients (72%).
Conclusion
The study confirms the negative impact of RTX on antibody level after vaccination against SARS-CoV-2. A clear relationship exists between antibody titre and interval of the last infusion to the first vaccination, number of peripheral B-cells and immunoglobulin quantity. These parameters help improve synchronization of vaccination and RTX therapy regimen.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
