Castleman disease patients report mild COVID-19 symptoms and mount a humoral response to SARS-CoV-2 vaccination.

ABSTRACT: The coronavirus disease of 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has resulted in increased morbidity and mortality in patients with impaired immunity, hematologic malignancies, and immunosuppressive regimens. COVID-19 can cause a cytokine storm with some patients benefiting from blockade of the pro-inflammatory cytokine, interleukin 6 (IL6). As Castleman disease (CD) is an atypical lymphoproliferative disorder that can involve a cytokine storm and often requires immunosuppressive therapies, including IL6 inhibition, we sought to evaluate outcomes following COVID-19 and SARS-CoV-2 vaccination in CD patients. We administered a survey in April 2021 to characterize experiences with COVID-19 and SARS-CoV-2 vaccination among 300 CD patients enrolled in ACCELERATE, a natural history registry of CD patients. Among 128 respondents, the prevalence of SARS-CoV-2 infection (16/95, 17%), severe disease (1/16, 6%), vaccination rates (112/128, 88%), and vaccine adverse effects after dose one (62/112, 55%) were comparable to the general U.S. population. While there were two cases of CD flares occurring shortly after SARS-CoV-2 infection (N=1) and vaccination (N=1), over 100 patients in this study that were infected and/or vaccinated did not experience CD flares. The median anti-spike titer six months after the second dose among CD patients was comparable to individuals with other immune-related diseases and healthy populations. Data from this small cohort suggest that, despite being on immunosuppressive therapies, CD patients do not appear to be at increased risk of poor COVID-19 outcomes and can mount a humoral response to SARS-CoV-2 vaccination. This study was registered on clinicaltrials.gov (#NCT02817997).

Project description:BackgroundThe humoral immune response after primary immunisation with a SARS-CoV-2 vector vaccine (AstraZeneca AZD1222, ChAdOx1 nCoV-19, Vaxzevria) followed by an mRNA vaccine boost (Pfizer/BioNTech, BNT162b2; Moderna, m-1273) was examined and compared with the antibody response after homologous vaccination schemes (AZD1222/AZD1222 or BNT162b2/BNT162b2).MethodsSera from 59 vaccinees were tested for anti-SARS-CoV-2 immunoglobulin G (IgG) and virus-neutralising antibodies (VNA) with three IgG assays based on (parts of) the SARS-CoV-2 spike (S)-protein as antigen, an IgG immunoblot (additionally contains the SARS-CoV-2 nucleoprotein (NP) as an antigen), a surrogate neutralisation test (sVNT), and a Vero-cell-based virus-neutralisation test (cVNT) with the B.1.1.7 variant of concern (VOC; alpha) as antigen. Investigation was done before and after heterologous (n = 30 and 42) or homologous booster vaccination (AZD1222/AZD1222, n = 8/9; BNT162b2/BNT162b2, n = 8/8). After the second immunisation, a subgroup of 26 age- and gender-matched sera (AZD1222/mRNA, n = 9; AZD1222/AZD1222, n = 9; BNT162b2/BNT162b2, n = 8) was also tested for VNA against VOC B.1.617.2 (delta) in the cVNT. The strength of IgG binding to separate SARS-CoV-2 antigens was measured by avidity.ResultsAfter the first vaccination, the prevalence of IgG directed against the (trimeric) SARS-CoV-2 S-protein and its receptor binding domain (RBD) varied from 55-95% (AZD1222) to 100% (BNT162b2), depending on the vaccine regimen and the SARS-CoV-2 antigen used. The booster vaccination resulted in 100% seroconversion and the occurrence of highly avid IgG, which is directed against the S-protein subunit 1 and the RBD, as well as VNA against VOC B.1.1.7, while anti-NP IgGs were not detected. The results of the three anti-SARS-CoV-2 IgG tests showed an excellent correlation to the VNA titres against this VOC. The agreement of cVNT and sVNT results was good. However, the sVNT seems to overestimate non- and weak B.1.1.7-neutralising titres. The anti-SARS-CoV-2 IgG concentrations and the B.1.1.7-neutralising titres were significantly higher after heterologous vaccination compared to the homologous AZD1222 scheme. If VOC B.1.617.2 was used as antigen, significantly lower VNA titres were measured in the cVNT, and three (33.3%) vector vaccine recipients had a VNA titre < 1:10.ConclusionsHeterologous SARS-CoV-2 vaccination leads to a strong antibody response with anti-SARS-CoV-2 IgG concentrations and VNA titres at a level comparable to that of a homologous BNT162b2 vaccination scheme. Irrespective of the chosen immunisation regime, highly avid IgG antibodies can be detected just 2 weeks after the second vaccine dose indicating the development of a robust humoral immunity. The reduction in the VNA titre against VOC B.1.617.2 observed in the subgroup of 26 individuals is remarkable and confirms the immune escape of the delta variant.
