Popis: BackgroundAn attenuated humoral response to SARS-CoV-2 vaccination has been observed in some patients with rheumatic and musculoskeletal diseases (RMD) (1). We sought to identify clinical factors associated with poor humoral response following primary (two-dose mRNA or single adenoviral vector dose) SARS-COV-2 vaccination in patients with RMD on immunosuppression.ObjectivesTo identify clinical predictors of an attenuated antibody response to primary SARS-CoV-2 vaccination in RMD patients on immunosuppression.MethodsWe included patients ≥18 years old with RMD on immunosuppression who received either two-dose mRNA or single dose Janssen/Johnson and Johnson (J&J) vaccination. Demographics, diagnoses, and therapeutic regimens were collected via participant report; those with prior COVID-19 infection were excluded. One month after vaccination, participants underwent SARS-CoV-2 antibody testing on the semi-quantitative Roche Elecsys anti-SARS-CoV-2 S enzyme immunoassay, which measures antibody to the SARS-CoV-2 S-receptor binding domain (RBD) protein (ceiling >250U/mL later expanded to >2500U/mL). Associations were evaluated using Fisher’s exact and Wilcoxon rank sum tests. Logistic regression analyses were performed to evaluate for clinical factors associated with antibody response. We adapted survival methods to address right-truncation of titers; this methodology was used to calculate medians. Participants provided informed consent electronically and the study was approved by the local Institutional Review Board.ResultsWe studied 1138 RMD participants on immunosuppression; most were female (93%) and white (91%) (Table 1). One-hundred and fifteen (10%) had anti-RBD response in the negative range at a median (IQR) of 29 days (28-34) following completion of vaccine series. A greater proportion of participants with negative response were non-white, received J&J vaccine, reported use of mycophenolate, rituximab, or glucocorticoids. Antibody response differed by immunosuppressive regimen, with those receiving rituximab having poorest response (Figure 1). Use of mycophenolate (aOR 9.92, p=0.001), rituximab (aOR 56.99, p=0.001), glucocorticoids (aOR 2.99, p=0.001) or receipt of J&J (aOR 3.13, p=0.039) were associated with negative antibody response.Table 1.Clinical characteristics stratified by anti-SARS-CoV-2 RBD responseNegative (n=115)*Positive (n=1023)*p-value†Age,median(IQR)49(42, 58)47(37, 58)0.07Female sex,no.(%)108(94%)952(93%)0.78Non-white,no.(%)16(13.9%)83(8.1%)0.04Diagnosis,no.(%)Inflammatory arthritis22(19.1%)469(45.8%)SLE27(23.5%)193(18.9%)0.27Sjὅgren’s syndrome5(4.3%)46(4.5%)0.53Myositis13(11.3%)49(4.8%)Systemic sclerosis2(1.7%)9(0.9%)0.55Vasculitis12(10.4%)16(1.6%)Overlap connective tissue disease¶34(29.5%)24(23.6%)0.65 Vaccine,no.(%) Pfizer/BioNTech66(57.4%)548(53.6%)0.01Moderna38(33.0%)438(42.8%)J&J11(9.6%)37(3.6%)Non-biologic in regimen89(77.4%)725(70.9%)0.52Biologic in regimen84(73.0%)570(55.7%)0.01 Mycophenolate**56(48.7%)120(11.7%) Rituximab54(47.0%)29(2.8%) Glucocorticoid**61(53.0%)284(27.8%)Withheld immunosuppression18(21.2%)260(39.6%)* Negative defined as anti-RBD titer † Comparisons between negative and positive groups.¶ Denotes a combination of two or more of the above conditions** Mycophenolate: mycophenolic acid and mycophenolate mofetil.
