ABSTRACT
Tattoo-associated sarcoidosis is characterized by granulomas in tattoos with or without the involvement of other organ systems such as the lungs and eyes. 18F-fluorodeoxyglucose (18F-FDG PET is a nuclear medicine imaging study that can differentiate between metabolically over-active areas and normal tissue. Thus, this review finds that 18F-FDG-PET/CT imaging can be used to image inflammatory activity in tattoos and in case of papulonodular tattoo reaction be used to investigate possible systemic sarcoidosis.

AIMS: In May 2020, a nationwide, web-based system for remote entry of patient-reported outcomes (PROs) in inflammatory rheumatic diseases was launched and implemented in routine care (DANBIO-from-home). After 1.5 years of use, we explored clinical characteristics of patients who did versus did not use the system, and the time to first entry of PROs. METHODS: All patients followed in DANBIO were informed about DANBIO-from-home by electronic invitations or when attending their clinic. Characteristics of patients who did/did not use DANBIO-from-home in the period after implementation were explored by multivariable logistic regression analyses including demographic and clinical variables (gender, age group, diagnosis, disease duration, use of biological disease-modifying agent (bDMARD), Health Assessment Questionnaire (HAQ), Patient Acceptable Symptom Scale (PASS)). Time from launch to first entry was presented as cumulative incidence curves by age group (<40/40-60/61-80/>80 years). RESULTS: Of 33 776 patients, 68% entered PROs using DANBIO-from-home at least once. Median (IQR) time to first entry was 27 (11-152) days. Factors associated with data entry in multivariate analyses (OR (95% CI)) were: female gender (1.19 (1.12 to 1.27)), bDMARD treatment (1.41 (1.33 to 1.50)), age 40-60 years (1.79 (1.63 to 1.97)), 61-80 years (1.87 (1.70 to 2.07), or age >80 years (0.57 (0.50 to 0.65)) (reference: age <40 years), lower HAQ (0.68 (0.65 to 0.71)) and PASS 'no' (1.09 (1.02 to 1.17). Diagnosis was not associated. Time to first entry of PROs was longest in patients <40 years of age (119 (24-184) days) and shortest in the 61-80 years age group (25 (8-139) days). CONCLUSION: A nationwide online platform for PRO in rheumatology achieved widespread use. Higher age, male gender, conventional treatment and disability were associated with no use.

OBJECTIVE: Successful uptake of biosimilars in rheumatology is limited by lack of real-world evidence regarding effectiveness of biosimilar-to-biosimilar switching. We investigated infliximab biosimilars CT-P13-to-GP1111 switching among patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (AxSpA). METHODS: Observational cohort study from the DANBIO registry. Patients were classified as originator-naïve or originator-experienced. Retention rates of 1-year GP1111 treatment were explored (Kaplan-Meier). We identified baseline factors (at the time of switch) associated with withdrawal of GP1111 (multivariable Cox-regression analyses with HRs including originator treatment history). Changes in subjective and objective measures of disease activity 4 months before and after the switch were assessed in individual patients. RESULTS: Of 1605 patients (685 RA, 314 PsA and 606 AxSpA, median disease duration was 9 years, 37% in Clinical Disease Activity Index/Ankylosing Spondylitis Disease Activity Score remission), 1171 were originator-naïve. Retention rates at 1-year were 83% (95% CI: 81% to 85%) and 92% (95% CI: 90% to 95%) for the originator-naïve and originator-experienced, respectively. GP1111 retention rates were higher in originator-experienced compared to originator-naïve with RA (HR=0.4 (95% CI: 0.2 to 0.7)) and PsA (HR=0.2 (95% CI: 0.1 to 0.8)), but not significantly for AxSpA: HR=0.6 (95% CI: 0.3 to 1.2). Lower disease activity was associated with higher retention. Changes in disease activity preswitch and postswitch were close to zero. CONCLUSION: This real-world observational study of more than 1600 patients with inflammatory arthritis showed high 1-year retention following a nationwide infliximab biosimilar-to-biosimilar switch. Retention was higher in originator-experienced and in patients with low disease activity, suggesting outcomes to be affected by patient-related rather than drug-related factors.

OBJECTIVE: To explore anxiety and self-isolation in patients with inflammatory rheumatic disease (IRD)15 months into the coronavirus disease 2019 (COVID-19) pandemic, including attitudes toward and effects of SARS-CoV-2 vaccination. METHODS: A nationwide online survey was conducted at 3 timepoints: May 2020, November 2020, and May 2021. Patients with IRD followed in the Danish Rheumatology Quality Registry (DANBIO) were asked about the effects of the pandemic, including SARS-CoV-2 infection and their behavior, anxiety, and concerns. The May 2021 survey included attitudes toward SARS-CoV-2 and influenza vaccination. Characteristics associated with self-isolation in May 2021 were explored with adjusted logistic regression analyses that included patient characteristics and SARS-CoV-2 vaccination status. RESULTS: Respondents to surveys 1, 2, and 3 included 12,789; 14,755; and 13,921 patients, respectively; 64% had rheumatoid arthritis and 63% were female. Anxiety and concerns were highest in May 2020 and decreased to stable levels in November 2020 and May 2021; 86%, 50%, and 52% of respondents reported self-isolation, respectively. In May 2021, 4% of respondents self-reported previous SARS-CoV-2 infection. The SARS-CoV-2 vaccine acceptance rate was 86%, and the proportion of patients vaccinated against influenza had increased from 50% in winter 2019-2020 to 64% in winter 2020-2021. The proportion of patients with anxiety appeared similar among those vaccinated and unvaccinated against SARS-CoV-2. In multivariable analyses, being unvaccinated, female gender, receiving biologic drugs, and poor quality of life were independently associated with self-isolation. CONCLUSION: Levels of anxiety and self-isolation decreased after the initial lockdown period in patients with IRD. Half of the patients reported self-isolation in May 2021, a phase that included widespread reopening of society and large-scale vaccination. The lack of prepandemic data prevented a full understanding of the long-term effects of the pandemic on anxiety and self-isolation in patients with IRD.

OBJECTIVES: To explore the impact of the COVID-19 pandemic on treat-to-target strategies (disease activity, remission rates) and access to physical consultations in patients with inflammatory rheumatic disease, as well as to explore characteristics of patients with/without physical consultations in the clinic and the impact of early vs established disease. METHODS: Patients with RA, PsA or axial SpA (axSpA) prospectively followed in the nationwide DANBIO registry answered online questionnaires and reported patient-reported outcomes (PROs) in June and November 2020. Patient characteristics, disease activity and physical consultations in the clinic before and during the pandemic were identified in DANBIO [all patients and subgroups with early disease (disease duration ≤2 years)]. In individual patients, changes in PROs before and during the pandemic were calculated. Characteristics of patients with/without physical consultations were described (age, gender, education level, comorbidities, disease duration, treatment). RESULTS: We included 7836 patients (22% of eligible patients), 12% of which had early disease. PROs were stable before and during the pandemic, with median changes approximating zero, as well as in patients with early disease. Remission rates were stable. The relative decrease in the number of patients with physical consultations was 21-72%, which was highest in axSpA. Characteristics of patients with/without physical consultations were similar. Self-reported satisfaction with treatment options and access was >70%; the preferred contact form was physical consultation (66%). CONCLUSION: In this nationwide study performed during the first 8 months of the pandemic, patient satisfaction was high and the PROs and remission rates remained stable despite the remarkable reduction in physical consultations, as well as in patients with early disease. Characteristics of patients with/without physical consultations appeared similar.

OBJECTIVES: In 2018, a nationwide mandatory switch from originator to biosimilar adalimumab was conducted in Denmark. The available biosimilar was GP2017 (Hyrimoz) in Eastern regions and SB5 (Imraldi) in Western regions. We aimed to assess the comparative effectiveness of GP2017 versus SB5 in patients with rheumatoid arthritis (RA)/psoriatic arthritis (PsA)/axial spondyloarthritis (AxSpA). METHODS: Observational cohort study based on the DANBIO registry with geographical cluster pseudo-randomisation, analysed by emulating a randomised clinical trial. Main outcome was adjusted 1-year treatment retention (Cox regression). Furthermore, 6 months' remission rates (logistic regression), reasons for withdrawal and back-switching to originator were investigated (overall and stratified by indication). RESULTS: Overall, of 1570 eligible patients, 1318 switched and were included (467 RA/321 PsA/530 AxSpA); 623 (47%) switched to GP2017, 695 (53%) to SB5. Baseline characteristics of the two clusters were largely similar, but some differences in registration practice were observed. The combined 1-year retention rate for the two biosimilars was 89.5%. Compared with SB5, estimated risk of withdrawal for GP2017 was lower (HR 0.60; 95% CI 0.42 to 0.86) and 6 months' remission rate was higher (OR 1.72; 95% CI 1.25 to 2.37). Stratified analyses gave similar results (statistically significant for RA). During 1 year, 8.5% and 12.9% withdrew GP2017 and SB5, respectively (primarily lack of effect and adverse events), of whom 48 patients (3.6%) back-switched. CONCLUSION: This head-to-head comparison of GP2017 versus SB5 following a mandatory switch from the originator indicated differences in effectiveness in routine care. This may reflect a true difference, but other explanations, for example, differences in excipients, differences between clusters and residual confounding cannot be ruled out.

AIMS: In Danish patients with inflammatory rheumatic diseases to explore self-protection strategies and health behaviour including adherence to disease-modifying antirheumatic treatment (DMARD) during the initial phase of the COVID-19 pandemic and again after the reopening of the society started. Furthermore, to identify characteristics of patients with high levels of anxiety and self-isolation. METHODS: Patients in routine care followed prospectively in the nationwide DANBIO registry were invited to answer an online questionnaire regarding disease activity and COVID-19 infection, behaviour in March and June 2020. Responses were linked to patient data in DANBIO. Characteristics potentially associated with anxiety, self-isolation and medication adherence (gender/age/diagnosis/education/work status/comorbidity/DMARD/smoking/EQ-5D/disease activity) were explored with multivariable logistic regression analyses. RESULTS: We included 12 789 patients (8168 rheumatoid arthritis/2068 psoriatic arthritis/1758 axial spondyloarthritis/795 other) of whom 65% were women and 36% treated with biological DMARD. Self-reported COVID-19 prevalence was 0.3%. Patients reported that they were worried to get COVID-19 infection (March/June: 70%/45%) and self-isolated more than others of the same age (48%/38%). The fraction of patients who changed medication due to fear of COVID-19 were 4.1%/0.6%. Female gender, comorbidities, not working, lower education, biological treatment and poor European Quality of life, 5 dimensions were associated with both anxiety and self-isolation. CONCLUSION: In >12 000 patients with inflammatory arthritis, we found widespread anxiety and self-isolation, but high medication adherence, in the initial phase of the COVID-19 pandemic. This persisted during the gradual opening of society during the following months. Attention to patients' anxiety and self-isolation is important during this and potential future epidemics.

OBJECTIVES: Real-world evidence on effectiveness of switching to biosimila r etanercept is scarce. In Denmark, a nationwide guideline of mandatory switch from 50 mg originator (ETA) to biosimilar (SB4) etanercept was issued for patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (AxSpA) in 2016. Clinical characteristics and treatment outcomes were studied in ETA-treated patients, who switched to SB4 (switchers) or maintained ETA (non-switchers). Retention rates were compared with that of a historic cohort of ETA-treated patients. Switchers who resumed ETA treatment (back-switchers) were characterised. METHODS: Observational cohort study based on the DANBIO registry. Treatment retention was explored by Kaplan-Meier plots and Cox regression (crude, adjusted). RESULTS: 1621 (79%) of 2061 ETA-treated patients switched to SB4. Disease activity was unchanged 3 months' preswitch/postswitch. Non-switchers often received 25 mg ETA (ETA 25 mg pens/syringes and powder solution were still available). One-year adjusted retention rates were: non-switchers: 77% (95% CI: 72% to 82%)/switchers: 83% (79% to 87%)/historic cohort: 90% (88% to 92%). Patients not in remission had lower retention rates than patients in remission, both in switchers (crude HR 1.7 (1.3 to 2.2)) and non-switchers (2.4 (1.7 to 3.6)). During follow-up, 120 patients (7% of switchers) back-switched to ETA. Back-switchers' clinical characteristics were similar to switchers, and reasons for SB4 withdrawal were mainly subjective. CONCLUSION: Seventy-nine per cent of patients switched from ETA to SB4. After 1 year, adjusted treatment retention rates were lower in switchers versus the historic ETA cohort, but higher than in non-switchers. Withdrawal was more common in patients not in remission. The results suggest that switch outcomes in routine care are affected by patient-related factors and non-specific drug effects.

OBJECTIVE: To examine determinants of thymus size at age 6 months and investigate whether thymus size at this age is a determinant of subsequent mortality. STUDY DESIGN: Thymus size was measured by transsternal sonography in 923 6-month-old children participating in a measles vaccination trial in Guinea-Bissau. RESULTS: Thymus size was strongly associated with anthropometric measurements. Boys had larger thymuses than girls, controlling for anthropometry. Crying during sonography made the thymus appear smaller. Children who were not vaccinated with Bacille Calmette-Guérin (BCG) or were vaccinated with BCG in the preceding 4 weeks before inclusion into the study had larger thymuses. Children who had malaria or had been treated with chloroquine or Quinimax in the previous week before inclusion had smaller thymuses. Controlled for background factors associated with thymus size and mortality, small thymus size remained a strong and independent risk factor for mortality (hazard ratio = 0.31; 95% confidence interval = 0.18 to 0.52). CONCLUSIONS: Small thymus size at age 6 months is a strong risk factor for mortality. To prevent unnecessary deaths, it is important to identify preventable factors predisposing to small thymus size.
