RESUMO
Background: There is scarce evidence on the rate of adverse events and the consequences on disease activity after vaccination against covid19 Objectives: To evaluate adverse events to vaccination and disease fares after vaccination in patients with axial spondyloarthritis (axSpA), peripheral spondy-loarthritis (pSpA) and psoriatic arthritis (PsA) and to evaluate factors associated with adverse event. Methods: Cross-sectional, observational, descriptive study. Consecutive patients with diagnosis of ankylosing spondylitis (AS) and non-radiographic axial spondy-loarthritis (nr-axSpA) according to ASAS 2009 criteria;pSpA according to ASAS 2011 criteria and PsA according to CASPAR criteria were included. Demographic data, disease clinimetry, treatments, vaccination received and post-vaccination adverse events were recorded. We evaluated, according to medical criteria, whether the patient presented a fare disease after vaccination and whether it was mild, moderate or severe. We also evaluated the factors associated with the presence of at least one mild adverse event. Statistical analysis: descriptive statistics were performed, qualitative variables were expressed as frequency and percentage (%), numerical variables as mean and standard deviation (SD) or median and percentile25-75. Binary logistic regression was performed using the presence of at least one mild adverse event to vaccination as the dependent variable. Results: 210 patients were included with a mean age of 45 (SD 15) years. The diagnoses were: AS 50 (23.8%), nr-axSpA 10 (4.8), pSpA 9 (4.3%), PsA 141 (67%) and time of disease evolution in months 109 (SD 96). Regarding comorbidities, the following frequencies were reported: arterial hypertension 60 (30%), diabetes mellitus 25 (12%), heart failure 4 (2%), asthma/EPOC 15 (7%), infammatory bowel disease 2 (1%), acute anterior uveitis 20 (9.5%), psoriasis 128 (61%). Sixteen percent (n=33) of the patients had SARS-CoV-2 infection prior to vaccination. Regarding treatments, those used were: antiTNF 88 (42%), Tofacitinib 6 (2.9%), Ustekinumab 2 (1%), Secukinumab 35 (17%), Ixekizumab 2 (1%), methotrexate 98 (47%), lefunomide 7 (3. 3), sulfasalazine 7 (3.3), apremilast 1 (0.5%), continuous NSAIDs 26 (12.4%) and NSAIDs on demand 103 (49%). Vaccines received were: Sputnik V 109 (51.9%), Oxford Vaccine, AstraZeneca 63 (30%), Janssen 1 (0.5%), BioNTech Vaccine, Pfzer 1 (0.5%), Sinopharm 33 (15.7%), Moderna 0%, Novavax 0% and others;3 (1.4%). Thirty-eight percent (n=80) of patients reported having mild post-vaccination symptoms, of which 3.75% did not resolve, 41% resolved with medication and 39% resolved ad integrum without medication. The presence of mild adverse event to the vaccine was associated with lower use of methotrexate (31% vs 56 %, p<0.001), and lower age (54 (SD 14) vs 47 (SD 12), p<0.001), and lower BMI (25 (24-30.5) vs 28 (25-31), p<0.001);while no association was found with sex, diagnosis, comorbidities, treatments, desease activity or vaccines. In the logistic regression analysis all the variables remained independently associated with a lower probability of presenting a mild adverse event: methotrexate: OR: 0.30, 95%CI 0.15-0.58, p<0.001, age: OR: 0.97, 95%CI 0.95-0.99, p: 0.03, BMI: OR: 0.92, 95%CI 0.95-0.99, p: 0.02. Sixty-one percent (n=129) of patients received the 2nd dose of vaccination, which 27% (n=35) presented mild adverse event and only 1 (0.8%) patient suffered post vaccination disease fare. Conclusion: Vaccination against COVID19 appears to be safe in this population, with only mild adverse events and low frequency of fare disease. Mild adverse events were associated with less use of methotrexate, younger age and lower BMI.
RESUMO
Background: In Argentina we have witnessed two COVID 19 waves between 2020 and 2021. The frst wave occurred during the spring of 2020 and it was related to the wild type of the virus, the second occurred during the fall/winter of 2021 when the gamma variant showed a clear predominance. During the frst wave, patient with rheumatic diseases showed a higher frequency of hospitaliza-tion and mortality (4% vs 0.26%) when compared to the general population1;at that time, however, vaccination was not yet available. Objectives: To compare sociodemographic and disease characteristics, course and outcomes of SARS-CoV-2 infection in patients with immune-mediated/auto-infammatory diseases (IMADs) during the frst and second waves in Argentina. Methods: SAR-COVID is a national, multicenter, longitudinal and observational registry, in which patients ≥18 years of age, with a diagnosis of a rheumatic disease who had confrmed SARS-CoV-2 infection (RT-PCR or positive serol-ogy) were consecutively included since August 2020. For the purpose of this report, only patients with IMADs who had SARS-CoV-2 infection during the frst wave (defned as cases occurred between March 2020 and March 2021) and the second wave (cases occurred between April and August 2021) were examined. Sociodemographic characteristics, disease diagnosis and activity, comorbidities, immunosuppressive treatment and COVID 19 clinical characteristics, complications and outcomes: hospitalization, intensive care unit (ICU) admission, use of mechanical ventilation and death were compared among groups. Descriptive statistical analysis was performed. Variables were compared with Chi squared test and Student T test or Mann Whitney test. Multivariable logistic regression models with forward and backward selection method, using hospitalization, ICU admission and death as dependent variables were carried out. Results: A total of 1777 patients were included, 1342 from the frst wave and 435 of the second one. Patients had a mean (SD) age of 50.7 (14.2) years and 81% were female. Both groups of patients were similar in terms of socio-de-mographic features, disease diagnosis, disease activity, the use of glucocorti-coids ≥ 10 mg/day and the immunosuppressive drugs (Table 1 below). Patients infected during the frst wave have higher frequency of comorbidities (49% vs 41%;p= 0.004). Hospitalizations due to COVID 19 (31% vs 20%;p <0.001) and ICU admissions (9% vs 5%;p= 0.009) were higher during the frst wave. No differences in the use of mechanical ventilation (16% vs 16%;p= 0.97) nor in the mortality rate (5% vs 4%;p= 0.41) were observed. In the multivariable analysis, after adjusting for demographics, clinical features and immunosup-pressive treatment, patients infected during the second wave were 40% less likely to be hospitalized (OR= 0.6, IC95% 0.4-0.8) and to be admitted to the ICU (OR= 0.6, IC95% 0.3-0.9). Conclusion: The impact of COVID 19 in Argentina, in terms of mortality in patients with IMADs was still higher compared to the general population during the second wave. However, the frequency of hospitalizations and ICU admissions was lower. These fndings could be explained by the introduction of the SARS COV 2 vaccination and, probably, by the cumulative knowledge and management improvement of this infection among physicians.
RESUMO
Background: Comorbidities, particularly cardio-metabolic disorders, are highly prevalent in patients with psoriatic arthritis (PsA) and they were associated with an increased risk of atherosclerotic cardiovascular disease, which have been associated with higher morbidity and mortality. Whether PsA enhances the risk of SARS-CoV-2 infection or affects the disease outcome remains to be ascertained. Objectives: To describe the sociodemographic, clinical and treatment characteristics of patients with PsA with confrmed SARS-CoV-2 infection from the SAR-COVID registry and to identify the variables associated with poor COVID-19 outcomes, comparing them with those with rheumatoid arthritis (RA). Methods: Cross-sectional observational study including patients ≥18 years old, with diagnosis of PsA (CASPAR criteria) and RA (ACR/EULAR 2010 criteria), who had confrmed SARS-CoV-2 infection (RT-PCR or serology) from the SAR-COVID registry. Recruitment period was between August 13, 2020 and July 31, 2021. Sociodemographic variables, comorbidities, and treatments were analyzed. To assess the severity of the infection, the ordinal scale of the National Institute of Allergy and Infectious Diseases (NIAID)1 was used, and it was considered that a patient met the primary outcome, if they presented criteria of categories 5 or higher on the severity scale. For this analysis, Chi2 test, Fisher's test, Student's test or Wilcoxon test, and binomial logistic regression using NIAID>=5 as dependent variable were performed. Results: A total of 129 PsA patients and 808 with RA were included. Clinical characteristics are shown in Table 1. Regarding PsA treatment, 12.4% of PsA were receiving IL-17 inhibitors, 5.4% IL12-23 inhibitors, one patient apremilast and one abatacept. The frequency of NIAID≥5 was comparable between groups (PsA 19.5% vs RA 20.1%;p=0.976). (Figure 1). PsA patients with NIAID≥5 in comparison with NIAID<5 were older (58.6±11.4 vs 50±12.5;p=0.002), had more frequently hypertension (52.2% vs 23%;p=0.011) and dyslipidemia (39.1% vs 15%;p=0.017). In the multivariate analysis, age (OR 1.06;95% CI 1.02-1.11) was associated with a worse outcome of the COVID-19 (NIAID≥5) in patients with PsA, while those who received methotrexate (OR 0.34;95% CI 0.11-0.92) and biological DMARDs (OR 0.28;95% CI 0.09-0.78) had a better outcome. Conclusion: Although PsA patients have a higher frequency of cardiovascular and metabolic comorbidities than those with RA, the COVID-19 severity was similar. Most of the patients had mild SARS-CoV-2 infection and a low death rate.
