Objectives Vaccination against COVID-19 emerges as an effective strategy for combating the pandemic. While many of our patients with rheumatic diseases (RD) wonder whether it is safe to get the vaccine, vaccine hesitancy is rising among the general population. We assessed the willingness to get vaccination and its probable predictors among patients with RD compared to healthcare workers and a sample from the general population. Methods We conducted a web-based questionnaire survey in a cross-sectional design in 3 groups of participants just before the mass vaccination program in Istanbul, Turkey. The questionnaire sought socio-demographic variables, COVID-19 related risk factors, willingness to get vaccination, and concerns and thoughts about vaccine. COVID-19 anxiety scale (CAS) was also evaluated. Results We studied in total 732 patients with RD (Group 1), 763 individuals representing general population (Group 2) and 320 hospital workers (Group 3). Dysfunctional anxiety related to COVID-19 was found in 4.9%, 3.8% and 4.1%, in Group 1, 2 and 3, respectively. Of the patients with RD, 29.2% were willing to be vaccinated, 19.0% were unwilling and 51.8% were undecided. These were somewhat similar among the general population (yes: 34.6%, no: 23.3% and unsure: 42.1%), with significantly less undecided individuals (p < 0.001). On the other hand, hospital workers were significantly more willing (yes: 52.5%, no: 20.9% and unsure: 26.6%) ( p < 0.001). Main concerns were probable side effects, unknown scientific results and having no trust. Being male, older age, working in a hospital, not having contracted COVID-19 and high scores on CAS were found to be independently associated with willingness. Conclusions The low rate of vaccine acceptance among patients with RD, as well as general population sampling is worrying. Healthcare policies should aim to implement communication, promote confidence and increase demand for COVID-19 vaccine.

Most of the published data relate to classical forms of rheumatic diseases (RD) and information on rare inflammatory disorders such as Behçet’s syndrome (BS) and familial Mediterranean fever (FMF) is limited. We studied the frequency of side effects and disease flares after COVID-19 vaccination with either Pfizer/BioNTech or Sinovac/CoronaVac in 256 patients with BS, 247 with FMF, and 601 with RD. Telephone interviews were conducted using a questionnaire survey in a cross-sectional design in patients with BS, FMF, and RD followed by a single university hospital. Study participants were vaccinated either with CoronaVac (BS:109, FMF: 90, and RD: 343,) or BioNTech (BS: 147, FMF: 157 and RD: 258). The majority have received double dose (BS: 94.9%, FMF 92.3% and RD: 86.2%). BioNTech ensured a significantly better efficacy than CoronaVac against COVID-19 in all patient groups (BS: 1.4% vs 10.1%; FMF: 3.2% vs 12.2%, RD:2.7% vs 6.4%). Those with at least one adverse event (AE) were significantly more frequent among those vaccinated with BioNTech than those with CoronaVac (BS: 86.4% vs 45%; FMF: 83.4% vs 53.3%; and RD: 83.3% vs 45.5%). The majority of AEs were mild to moderate and transient and this was true for either vaccine. There were also AEs that required medical attention in all study groups following CoronaVac (BS: 5.5%, FMF: 3.3%, and RD:2.9%) or BioNTech (BS: 5.4%, FMF: 1.9%, and RD: 4.7%). The main causes for medical assistance were disease flare and cardiovascular events. Patients with BS (16.0%) and FMF (17.4%) were found to flare significantly more frequently when compared to those with RD (6.0%) ( p < 0.001). This was true for either vaccine. BS patients reported mainly skin-mucosa lesions; there were however, 11 (4.3%) who developed major organ attack such as uveitis, thrombosis or stroke. Flare in FMF patients were associated mainly with acute serositis with or without fever. Arthralgia/arthritis or inflammatory back pain were observed mainly in the RD group. Our study demonstrates that BS and FMF patients vaccinated with either CoronaVac or BioNTech demonstrated similar AE profile and frequency compared to RD patients. AEs that required physician consultation or hospitalization occurred in all study groups after either CoronaVac or BioNTech. Increased frequency of flares in BS and FMF compared to that seen in RD might reflect defects in innate immunity and deserves further investigation. Caution should be required when monitoring these patients after vaccination.

Secukinumab is a human monoclonal antibody against IL-17A that has been shown to be effective in psoriasis, psoriatic arthritis and ankylosing spondylitis (AS). On the other hand, in randomized controlled trials among patients with Crohn’s disease (CD) and uveitis due to Behçet’s syndrome (BS) treated with secukinumab, primary end points were not met and the drug caused more exacerbations compared to placebo. The drug fact sheet states that secukinumab should be used with caution in patients with CD; however, there are no warnings for those with BS. Here, we present two patients with AS treated with secukinumab; we observed exacerbation of BS in one and emergence of de novo BS in another. Although IL-17A is thought to contribute to the pathogenesis of BS, our observations suggest that it might have a protective role. Finally, we suggest caution is required with the inhibition of IL-17 in BS.

BackgroundThe course of novel coronavirus disease 2019 (COVID-19) has been of special concern in patients with inflammatory rheumatic diseases (IRDs) due to the immune dysregulation that may be associated with these diseases and the medications used for IRDs, that may affect innate immune responses.ObjectiveIn this cohort study, we aimed to report the disease characteristics and variables associated with COVID-19 outcome among Turkish patients with IRDs.MethodsBetween April and June, 2020, 167 adult IRD patients with COVID-19 were registered from 31 centers in 14 cities in Turkey. Disease outcome was classified in 4 categories; (i) outpatient management, (ii) hospitalization without oxygen requirement, (iii) hospitalization with oxygen requirement, and (iv) intensive care unit (ICU) admission or death. Multivariable ordinal logistic regression analysis was conducted to determine variables associated with a worse outcome.Results165 patients (mean age: 50 ± 15.6 years, 58.2% female) were included. Twenty-four patients (14.5%) recovered under outpatient management, 141 (85.5%) were hospitalized, 49 (30%) required inpatient oxygen support, 22 (13%) were treated in the ICU (17 received invasive mechanic ventilation) and 16 (10%) died. Glucocorticoid use (OR: 4.53, 95%CI 1.65-12.76), chronic kidney disease (OR: 12.8, 95%CI 2.25-103.5), pulmonary disease (OR: 2.66, 95%CI 1.08-6.61) and obesity (OR: 3.7, 95%CI 1.01-13.87) were associated with a worse outcome. Biologic disease-modifying antirheumatic drugs (DMARDs) do not seem to affect COVID-19 outcome while conventional synthetic DMARDs may have a protective effect (OR: 0.36, 95%CI 0.17-0.75). Estimates for the associations between IRD diagnoses and outcome were inconclusive.ConclusionsAmong IRD patients with COVID-19, comorbidities and glucocorticoid use were associated with a worse outcome, while biologic DMARDs do not seem to be associated with a worse outcome.
