ABSTRACT

Background: The interaction between checkpoint inhibitors (CPI) and Sars-COV-2 vaccines has been understudied. One potential complication in pts receiving CPI is immune-mediated adverse events (irAEs) resulting from overactivation of the immune system. It is unknown whether concurrent CPI and Sars-COV-2 vaccine administration increases the risk of irAEs. This retrospective study examined the incidence of severe irAEs in cancer patients receiving CPI therapy at the time of vaccination against Sars CoV-2. Method(s): Following IRB approval, pts with solid tumors who received any approved CPI since FDA authorization of the COVID-19 vaccine in December 2020 were identified via institutional electronic health record. Pts who received one or more doses of an authorized vaccine within 60 days of CPI treatment were included. The primary endpoint was to evaluate the incidence of severe irAE (one or more of the following: grade 3 AE or above, multi-system involvement, need for hospitalization). Secondary endpoints included time between CPI and vaccination, need for immunosuppressive therapy, and rate of discontinuation of CPI due to irAE. Data was analyzed using descriptive statistics. Result(s): 290 pts with bladder, head/neck, liver, skin (melanoma, SCC), renal, and gynecologic cancer were included in analysis. The median age was 67 years (IQR: 59.0-74.0) and 66% pts were male. At the time of vaccination, 201 pts (69.3%) received CPI monotherapy, 53 pts (18.3%) received combination (combo) CPI therapy, and 36 pts (12.4%) received other therapies (chemo, TKIs, etc.) with CPI. The vaccine manufacturer was Pfizer Bio-N-Tech in 162 pts (55.9%), Moderna in 122 pts (42.1%), and Johnson and Johnson in 6 pts (2.1%). The number of vaccinations received was >/= 3 in 214 pts, 2 in 64 pts, and 1 in 11 pts. 30 pts (11.5%) experienced severe irAEs following vaccination. The rate of severe irAEs was 10.3% (30/290) in the total population [6% (12/201) with CPI monotherapy, 19% (10/53) with combo CPI, and 22% (8/36) in the combo CPI-other group]. Severe irAEs occurred after the first vaccine dose in 5 pts (16.7%), second dose in 16 pts (53.3%), and third dose in 9 pts (30%) pts. The median time between CPI treatment and vaccination in pts who experienced irAE was15.5 days (IQR: 10.2-23.0). Hospitalization was required for 19 patients (63.3%). 24 pts (80.0%) required immunosuppressive therapy with a median therapy duration of 98.5 days (IQR 40.2-173.0). 16 pts (53.5%) discontinued CPI therapy following severe irAEs Conclusion(s): In this retrospective study, we observed a 10.3% rate of severe irAE in cancer pts receiving CPI concurrently with COVID-19 vaccines. Further investigation in pts with additional cancer types is warranted to help determine best practice guidelines for COVID-19 vaccination in cancer patients receiving CPI.

ABSTRACT

Background: COVID-19 vaccination recommendations for cancer patients (pts) are similar to the general population. The interaction between checkpoint inhibitors (CPI) and Sars-COV-2 vaccines has been understudied. One potential complication in pts receiving CPI is the occurrence of immune-mediated adverse events (irAEs) resulting from overactivation of the immune system. This retrospective study examined the incidence of severe irAEs in pts with bladder urothelial cancer (UC) treated with CPI therapy who received concurrent vaccinations against Sars-CoV-2. Method(s): Following IRB approval, UC pts who received any approved CPI treatment since FDA authorization of the first COVID-19 vaccine in December 2020 were identified via institutional electronic health record. Pts who received 1 or more doses of an authorized vaccine within 60 days of CPI treatment were included. The primary endpoint was to evaluate the incidence of severe irAE (defined as one or more of the following: grade 3 AE or above, multi-system involvement, need for hospitalization). Secondary endpoints included time between CPI and vaccination, need for immunosuppressive therapy, and rate of discontinuation. Data was analyzed using descriptive statistics. Result(s): Forty pts were included in our analysis with a median age of 72.5 years (IQR: 66.0-79.2);82% pts were male. At the time of vaccination, 37 pts (92.5%) received CPI monotherapy, 2 pts (5.0%) received combination (combo) CPI therapy, and 1 pt (2.5%) received combo platinum-based chemotherapy and CPI. The vaccine manufacturer was Pfizer Bio-NTech in 22 pts (55.0%), Moderna in 17 pts (42.5%), and Johnson and Johnson in 1 pt (2.5%). Number of vaccinations received was>/= 3 in 27 pts, 2 in 11 pts, and 1 in 2 pts. Six pts (15.0%) experienced severe irAEs following vaccination, including nephritis, colitis, pneumonitis, DKA, and infusion-related reaction. Rates of severe irAEs were 16.2% (6/37) with CPI monotherapy, no severe irAEs occurred in the combo CPI and combo CPI-chemo groups. Severe irAEs occurred after the first vaccine dose in 1 pt (16.7%), second dose in 3 pts (50.0%), and third dose in 2 pts (33.3%) pts. The median time between CPI treatment and vaccination in this group was 22.0 days (IQR: 15.8-36.5. Hospitalization was required for all 6 patients (100%). Three pts (50.0%) required immunosuppressive therapy with a median therapy duration of 64.0 days (IQR 47.0-83.5). Five pts (83.3%) discontinued CPI therapy following severe irAEs. Conclusion(s): In this retrospective study, we observed a 15% rate severe irAE in UC pts receiving CPI concurrently with COVID-19 vaccines. Further investigation in pts with additional cancer types is warranted to help determine best practice guidelines for COVID-19 vaccination in cancer patients receiving CPI.

ABSTRACT

Background: Immune-mediated adverse events (irAEs) can be seen in patients (pts) receiving checkpoint inhibitors (CPI). It is unknown whether the immune response to vaccines against Sars-CoV-2 interacts with the immune activation from CPI therapy. In this retrospective study, we examined the incidence of severe irAEs in pts with renal cell carcinoma (RCC) who received vaccines against Sars-CoV-2 during the course of their CPI therapy. Methods: Following IRB approval, RCC pts who received any CPI treatment since FDA authorization of the first COVID-19 vaccine in March 2021 were identified via institutional electronic health record. Pts who received one or more doses of an authorized vaccine within 60 days of CPI treatment were included. The primary endpoint was to evaluate the incidence of severe irAE (defined as one or more of the following: grade 3 AE or above, multi-system involvement, need for hospitalization). Secondary endpoints included time between CPI and vaccination, need for immunosuppressive therapy, and rate of discontinuation. Data was analyzed using descriptive statistics. Results: Sixty-five pts were included in our analysis with a median age of 66 years (IQR: 58.0, 73.0);80% pts were male. At the time of vaccination, 26 pts (40.0%) received CPI monotherapy, 12 pts (18.4%) received combination (combo) CPI therapy, and 27 pts (41.6%) received combo therapy with a tyrosine kinase inhibitor (TKI) and CPI. The type of vaccine received was Pfizer Bio-NTech in 30 pts (46.2%), Moderna in 33 pts (50.7%), and Johnson and Johnson in 2 pts (3.1%). Six pts received only one vaccination (9.2%), 18 pts received two vaccinations (27.7%), and 40 pts received 3 or more vaccinations (61.5%). Eleven pts (16.9%) experienced severe irAEs following vaccination. Rates of severe irAEs was 3.8% (1/26) with CPI monotherapy, 25% (3/12) with combo CPI, and 25.9% (7/27) with combo CPI and TKI. Severe irAEs occurred after the first vaccine dose in 4 pts (36.4%), second dose in 3 pts (27.3%), and third dose in 4 pts (36.4%) pts. The median time between CPI treatment and vaccination in this group was 11.0 days (IQR: 7.5-15.5). Hospitalization was required for 6 patients (54.5%). Ten pts (90.9%) required immunosuppressive therapy with a median steroid duration of 85.5 days (IQR 36.8, 176.0). Six pts (54.5%) discontinued CPI therapy following severe irAEs. Conclusions: In this retrospective study, the observed rate of severe irAEs in RCC patients who received CPI and COVID-19 vaccine concomitantly was similar to historical controls, suggesting that there is no definite increase in the incidence of severe irAEs in pts undergoing CPI therapy and receiving COVID-19 vaccination. Future confirmatory studies are warranted.

ABSTRACT

Purpose: This research studies the influence of the COVID-19 pandemic on the operation management of Hong Kong academic libraries for understanding the difficulties and challenges for librarians to adapt to the special arrangements during the pandemic. Design/methodology/approach: Qualitative semi-structured interviews were conducted with librarians in major universities and higher education institutions of Hong Kong. Participants were interviewed either in the face-to-face format or text-based format. Findings: Participants provided a broad scope about the actual library management and operation changes during the COVID-19. According to the respondents, the most challenging problem for librarians during COVID-19 was to strike a balance between concerns of library staff and users. While they described how these arrangements and changes affected the service quality of academic libraries from different perspectives, the pandemic situation also brought some opportunities, such as pushing the digitalization of all collections and using online resources for future development. A hybrid model for library service would be more common in the future with more demands toward online resources and digital collection, in which academic libraries should be prepared after the pandemic. Originality/value: This paper provided broad insights into library management and the future development of academic libraries for the post-COVID-19 period. There are scant studies of this topic, especially in an Asian metropolis context with dense population, small campus and limited library physical spaces. © 2022, Emerald Publishing Limited.
