New onset or exacerbation of pre-existing psoriasis after therapeutic TNF-α inhibition is a well-described phenomenon. Over the last two decades, similar cases of paradoxical psoriasis have been reported following the administration of other biologic agents. We aimed to review all published cases of induced or exacerbated psoriasis after biologic therapy other than anti-TNF-α agents in order to further elucidate the pathophysiology of this phenomenon. A systematic literature review in the Medline database regarding any relevant case series or case reports on new onset or exacerbation of psoriasis after the administration of biologic agents targeting B cells, T cell co-stimulation, interleukin-1, interleukin-6, interleukin-17 and interleukin-12/23 was performed using appropriate key words. The literature search revealed nine articles (nine cases) of paradoxical psoriasis after ustekinumab and eight articles (nine cases) after secukinumab administration, both of which are approved therapies for psoriasis Moreover, 15 articles (23 cases) for rituximab, nine articles (12 cases) for abatacept, eight articles (nine cases) for tocilizumab, and one case report for anakinra have been published. In the majority of cases, patients had no prior history of psoriasis while 18 patients presented with exacerbation of pre-existing psoriatic lesions. Paradoxical psoriasis is not a specific adverse event of TNF-α inhibitors but is a possible side effect of any biologic agent interfering with the immune system. Awareness among physicians regarding early recognition is mandatory. Further clinical and experimental data are needed in order to unravel the pathophysiology of this unexpected phenomenon.

We read with great interest the article of Meara et al1 in your journal describing a case of chilblain-like lesions after vaccination against SARS-CoV-2. Since the start of the coronavirus disease 2019 (COVID-19) pandemic, millions of vaccine doses have been administered and their safety has been generally confirmed.

To assess non-compliance and potential changes in seasonal flu vaccination coverage before and during the Covid-19 pandemic in patients with autoimmune rheumatic diseases (ARDs). Consecutive patients with ARDs followed-up in 2 tertiary hospitals were telephone-interviewed (December 12–30, 2020) regarding seasonal flu vaccination during the 2019/20 and 2020/21 time periods. Self-reported disease flares that occurred after flu vaccination, as well as reasons for non-vaccination were recorded. One thousand fifteen patients were included. The rate of flu vaccination increased from 76% before to 83% during the COVID-19 pandemic (p = 0.0001). The rate of self-reported disease flares was

Objectives:\ud Longitudinal studies using validated tools to evaluate depression and anxiety in psoriatic arthritis (PsA) are lacking. We aimed to estimate their course in PsA and to examine possible associations with disease-related parameters and patient-reported outcomes (PROs).\ud Methods:\ud PsA patients attending two outpatient rheumatology clinics were consecutively enrolled (January 2019-June 2021, n=128). The hospital anxiety and depression scale (HADS) was used at two sequential visits (mean±SD: 10±6 months) to prospectively assess depression (HADS-Depression) and anxiety (HADS-Anxiety) (cut-off scores ≥11). Associations with demographic, clinical, laboratory features and PROs for quality of life (QoL) (EQ-5D), functional status (HAQ-DI) and nocebo-behaviour (Q-No) were examined. ‘Change’ was the difference between values at the first and second visit.\ud Results:\ud Prevalence of depression and anxiety at the first visit was 19.5% and 21.1%, respectively. Depression was associated with EQ-5D [OR (95% CI): 1.70 (1.02-2.59), p=0.019] and anxiety with EQ-5D [1.81 (1.20 to 2.72), p=0.005], nocebo-behaviour [1.19 (1.01-1.40), p=0.04] and current corticosteroid use [6.95 (1.75-27.59), p=0.006]. At the second visit, HADS-Depression and HADS-Anxiety scores were improved in 40.9% and 41.9% of patients, respectively. While no associations were found for HADS-Anxiety score change, changes in HADS-Depression score correlated with changes in subjective (tender joint count, r= 0.204, p=0.049; PtG, r= 0.236, p=0.023; patient pain assessment, r= 0.266, p=0.01) but not objective (swollen joint count, ESR, CRP) parameters of disease activity.\ud Conclusions:\ud In PsA, depression and anxiety are associated with worse PROs, including QoL. Subjective parameters of disease activity parallel course of depression.

Objectives: Data on COVID-19 in patients with interstitial lung disease are scarce and whether SARS-CoV-2 may trigger interstitial lung disease progression remains unknown. We aimed to analyze outcomes of COVID-19 in patients with systemic sclerosis–associated interstitial lung disease, including possible thoracic radiographic progression. Patients and Methods: All 43 patients with systemic sclerosis–associated interstitial lung disease followed in our center (mean ± SD, 55.2 ± 11.6 years, 36 female) with confirmed SARS-CoV2 infection up to 1 September 2022 were analyzed. Individual interstitial lung disease extent on high resolution CT (HRCT) performed before (up to 3 months) and after COVID-19 (2–5 months) was compared. Results: At SARS-CoV-2 infection, 9/43 patients were unvaccinated, whereas 5, 26, and 3 had received 2, 3, or 4 doses of an mRNA vaccine, respectively. Thirty-one patients were either on monotherapy with immunosuppressives (mycophenolate, n = 7; cyclophosphamide, n = 2; methotrexate, n = 10; tocilizumab, n = 7; rituximab, n = 1; etanercept, n = 1), or their combinations ( n = 3). Eight patients (20%), of whom four unvaccinated, required hospitalization for pneumonia and three (7%) died of acute respiratory failure ( n = 2, both unvaccinated) or cardiac arrest. Lack of vaccination was the only independent predictor for hospitalization (OR = 7.98, 95% CI: 1.25–51.09) and marginally for death (OR = 32.7, 95% CI: 0.97–1110.98), regardless of the presence of diffuse systemic sclerosis, interstitial lung disease extent greater than 20% or immunosuppressive treatment. In 22 patients with available HRCT pairs (vaccinated = 20), the interstitial lung disease extent before COVID-19 (20.4%± 17.8%) remained unchanged (22.4% ± 18.5%) in all but one patient. Conclusion: SARS-CoV-2 vaccination is of outmost importance for every systemic sclerosis patient with interstitial lung disease. COVID-19 does not seem to promote progression of systemic sclerosis–associated interstitial lung disease in vaccinated patients, but further studies are warranted.

ObjectiveΤo report outcomes of breakthrough COVID-19 in comparison with COVID-19 in unvaccinated patients with systemic rheumatic diseases (SRDs).MethodsPatients with SRD with COVID-19 (vaccinated and unvaccinated) were included by their rheumatologists in a registry operated by the Greek Rheumatology Society in a voluntarily basis. Type, date and doses of SARS-CoV-2 vaccines were recorded, and demographics, type of SRD, concurrent treatment, comorbidities and COVID-19 outcomes (hospitalisation, need for oxygen supplementation and death) were compared between vaccinated and unvaccinated patients.ResultsBetween 1 March 2020 and 31 August 2021, 195 patients with SRD with COVID-19 were included; 147 unvaccinated and 48 vaccinated with at least one dose of a SARS-CoV-2 vaccine (Pfizer n=38 or AstraZeneca n=10). Among vaccinated patients, 29 developed breakthrough COVID-19 >14 days after the second vaccine dose (fully vaccinated), while 19 between the first and ConclusionsVaccinated patients with SRD with breakthrough COVID-19 have better outcomes compared with unvaccinated counterparts with similar disease/treatment characteristics.

Objective To describe the rate and type of adverse effects (AEs) and the frequency of disease flares after COVID-19 vaccination and to assess the reasons for vaccination hesitancy (non-vaccination) in SRD patients. Methods Telephone interviews were conducted of SRD patients consecutively enrolled (15/06/2021-1/7/2021). Participants were asked about the type of AEs and disease flare after vaccination. Reasons for vaccination hesitancy were recorded. Univariate and mutivariable analyses examined associations of demographic, clinical and other features, with occurrence of AEs, disease flare and non-vaccination. For the latter, association with negative vaccination behaviour (not influenza vaccinated for the last 2 years) and nocebo-prone behaviour (denoting AEs attributed to negative expectations [Q-No questionnaire]) was also tested. Results 561 out of 580 contacted patients were included in the study. 441/561 (78.6%) patients were vaccinated [90% (Pfizer, Moderna), 10% (Astra-Zeneca)]. AEs were reported by 148/441 (33.6%), with rates being comparable between the three vaccines. AEs were more common in females and those with chronic obstructive pulmonary disease [OR, 95% CI; females: 2.23 (1.30-3.83); COPD: 3.31 (1.24-8.83)]. Disease flare was reported in 9/441 (2%) patients. For those unvaccinated, fear that the vaccine would be harmful (53.3%), could cause disease flare (24.2%) and/or could cause thrombosis (21.7%) were the main reasons to do so. Multivariable analysis identified as independent variables for non-vaccination: nocebo-prone behaviour (OR; 95% CI, 3.88; 1.76-8.55), negative vaccination behaviour (6.56; 3.21-13.42) and previous COVID-19 infection (2.83; 1.13-7.05). Higher educational status was protective (0.49; 0.26-0.92). Conclusion No new safety signals for COVID-19 vaccination were observed. Vaccination campaign should target SRD patients with nocebo-prone and negative influenza vaccination behaviour.

To assess the possible impact conferred by co-existing variants in MEditerranean FeVer (MEFV) and other genes on systemic autoinflammatory disease (SAID) phenotype.Consecutive patients (n = 42) who underwent screening for SAIDs by next generation sequencing (NGS) targeting 26 genes, and carried at least one MEFV gene variant, were retrospectively studied. A total of 63 MEFV gene variants mainly located in exon 10 (n = 29) and exon 2 (n = 19) were identified in 21 patients with juvenile- and 21 with adult-onset disease.The candidate clinical diagnosis was Familial Mediterranean Fever (FMF) in 11, polygenic SAIDs (PFAPA, Still's disease, atypical SAPHO and inflammatory bowel disease) in 9, whereas the disease could not be clinically defined in 22 patients. Notably, 33 out of the 42 patients (79%) had at least one co-existing variants in 19 genes other than MEFV. NGS confirmed all clinical diagnoses and helped defining diagnosis in 59% of the remaining cases. Patients with undefined SAIDs (n = 9) or atypical FMF phenotype (n = 12) carried significantly more disease-causing variants in genes other than MEFV compared to patients with typical FMF (n = 9). More than one variants in these genes were significantly associated with adult-onset disease, while disease-causing variants in the same genes were also associated with an overall more severe SAID phenotype.Co-existing variants in SAID-related genes may explain the phenotypic variability of these diseases. Further studies should validate combined molecular and clinical data in order to better understand the cumulative gene dosage effect and improve the classification of these patients.

Background The COVID-19 pandemic is associated with emotional distress and significant disruptions in health-care services. These are key players in the development of nocebo phenomena. We aimed to investigate nocebo-prone behaviour in patients with autoimmune rheumatic diseases (ARD) amid the COVID-19 pandemic-associated lockdown. Methods Consecutive patients were telephone-interviewed during the COVID-19 pandemic in Greece. Clinical and socioeconomic characteristics (eg, level of education) were recorded. For nocebo behaviour, a four-item validated questionnaire (Q-No, cut-off score>15), was used. Results were compared with pre-COVID-19 Q-No scores collected from patients followed-up in our department. Results Nocebo behaviour was detected in 51/500 (10.2%) individuals. In patients with nocebo behaviour, use of anti-hypertensives was less common (17.6% vs 31.8%, p=0.04), but a higher level of education was more common (58.8% vs 35.9%, p=0.002), compared with patients with Q-No score ≤15; the latter retained statistical significance in multivariate regression analysis (p=0.009, OR [95%CI]: 2.29, [1.23-4.25]). Total Q-No scores were higher in the COVID-19-period compared to the pre-COVID-19 era [median (range); 12 (4-20) vs 11 (4-20), p=0.02]. Among 78 patients with available Q-No questionnaires in the pre-COVID-19 era, 11 (14.1%) displayed nocebo behaviour, which increased to 16 (20.5%) amid the COVID-19 pandemic. Interim development of nocebo behaviour was also associated with higher educational level (p=0.049, OR: 3.65, 95%CI: 1.005-13.268). Conclusion A considerable proportion of ARD patients manifested nocebo-prone behaviour during the COVID-19 pandemic, which was more common among those with high educational level.

We read with great interest the preliminary German Society of Rheumatology recommendations for the management of patients with autoimmune inflammatory rheumatic diseases (AIRD) during the COVID-19 pandemic.1 As other regulatory bodies suggest2 3 patients should not discontinue their anti-rheumatic treatment because of fear.1 Herein, we investigated to which extent patients with AIRD altered their treatment during COVID-19 pandemic and whether there are any factors that affected their decision. We telephone-interviewed (14 April 2020–22 April 2020), 500 consecutive AIRD-patients followed-up in our centre and recorded the following parameters: age, sex, cohabitation, region of residence (urban, semiurban, rural), level of education (first, second, third), employment status, disease duration, current treatment and presence of co-morbidities (hypertension, hyperlipidemia, coronary heart disease, diabetes mellitus, chronic obstructive pulmonary disease (COPD), depression, anxiety). Specific questions referred to the COVID-19 pandemic period in Greece, starting on 26 February 2020, with predefined answer-options, were asked: discontinuation of any medication received for AIRDs, possible reasons that led to drug discontinuation (including fear of immunosuppresion and lack of resources/drug shortage), whether advise was received from a clinician or other sources, symptomatology compatible with COVID-19 infection, subjective assessment (on …
