ABSTRACT

BackgroundMyeloma patients frequently respond poorly to bacterial and viral vaccination. A few studies have reported poor humoral immune responses in myeloma patients to COVID-19 vaccination. MethodsUsing a prospective study of myeloma patients in UK Rudy Study cohort, we assessed humoral and Interferon gamma release assay (IGRA) cellular immune responses to COVID-19 vaccination post second COVID-19 vaccine administration. FindingsWe report data from 214 adults with myeloma (n=204) or smouldering myeloma (n=10) who provided blood samples at least 3 weeks after second vaccine dose. Positive Anti-Spike antibody levels (> 50 IU/ml) were detected in 189/203 (92.7%), positive IGRA responses were seen in 97/158 (61.4%) myeloma patients. Only 10/158 (6.3%) patients were identified to have both a negative IGRA and negative Anti-Spike protein antibody response. 95/158 (60.1%) patients produced positive results for both anti-Spike protein serology and IGRA. After adjusting for disease severity and myeloma therapy, poor humoral immune response was predicted by male gender. Predictors of poor IGRA included anti-CD38/ anti-BCMA therapy and Pfizer-BioNTech (PB) vaccination. InterpretationSignificant majority of myeloma patients elicit Anti-Spike protein antibody responses to COVID-19 vaccine with 60% of myeloma patients showing both humoral and T cell response. Predictors of a poor immune response included male gender, myeloma therapy regimen and administration of Pfizer-BioNTech vaccination. Further work is required to understand the clinical significance of divergent cellular response to vaccination. FundingFunding for this study has been received from Blood Cancer Vaccine Consortium and Janssen UK. RUDY platform has been funded by NIHR.

ABSTRACT

ObjectiveMultiple myeloma (MM)-related morbidity has a profound effect on quality of life (QoL), and immune function, but few studies have prospectively examined the impact of COVID-19 pandemic and attendant vaccination on both immunity and QoL of patients with MM. We aimed to characterise these effects in a prospective cohort study. DesignWe initiated a prospective national cohort study of patients with MM from start of the second wave of SARS CoV-2 infections in December 2020 and resultant COVID lockdown in the United Kingdom. We assessed current myeloma status, history of COVID19 symptoms, testing and vaccination including response using the rudystudy.org platform. In addition, healthcare resource use, mental and social well being and loneliness (Lubben scale) from the start of the COVID-19 pandemic were assessed. ParticipantsWe report data from the first one hundred and nine adults with MM who completed the questionnaires and the first round of blood testing in the cohort. ResultsFive patients (4.5%) had COVID-19 infection confirmed by history and/or testing (Nucleocapsid antibody). Up to 98% of patients shielded completely or partially during both waves of the pandemic, with 18% of patients consequently changing antimyeloma therapy in the shielding period. Using the Lubben scale, 21/99 (21.2 %) reported social isolation. Using HADS scale 23.1% of patients reported symptoms of mild to moderate anxiety or mild to moderate depression during this period. Humoral immune response (spike ab) tested 3 weeks after first vaccination was detected in 17/28 (60%) patients. ConclusionMyeloma patients shielded during waves of the pandemic with significant change to therapy, low level natural COVID-19 infection (4%) and social isolation. Humoral response following the first dose of COVID-19 vaccine is lower than that reported in non-myeloma cohorts. What is already known on this topicLimited published data exist on the effect of the COVID-19 pandemic on myeloma patients. Post first vaccine response in myeloma patients has been reported in a small number of patients from two studies ranging from 25 % to 56%. What this study addsThis study reports myeloma patients shielded during waves of the pandemic and demonstrates consequent significant social isolation and changes to therapy. Low level natural COVID-19 infection (4%) was noted in the study and humoral response following first dose of COVID-19 vaccine was lower than that reported in non-myeloma cohorts.

ABSTRACT

BackgroundThere has been great concern amongst clinicians and patients that immunomodulatory treatments for IBD may increase risk of SARS-CoV-2 susceptibility or progression to severe disease. MethodsSera from 640 patients attending for maintenance infliximab or vedolizumab infusions between April and June 2020 at the John Radcliffe Hospital (Oxford, UK) and Royal London Hospital (London, UK) were tested using the Abbott SARS-CoV-2 IgG assay. Demographic and clinical data were collated from electronic patient records and research databases. ResultsSeropositivity rates of 3.0% (12/404), 7.2% (13/180), and 12.5% (7/56) were found in the Oxford and London adult IBD cohorts and London paediatric IBD cohorts respectively. Seroprevalence rates in the Oxford adult IBD cohort were lower than that seen in non-patient facing health-care workers within the same hospital (7.2%). Seroprevalence rates of the London paediatric IBD cohort were comparable to a contemporary healthy cohort collected at the same hospital (54/396, 13.6%). ConclusionsSARS-CoV-2 seropositivity rates are not elevated in patients with IBD receiving maintenance infliximab or vedolizumab infusions. There is no rationale based on these data for elective interruption of maintenance therapy, and we recommend continuation of maintenance therapy. These data do not address the efficacy of vaccination in these patients.
