Psoriasis as a Systemic Disease.

BACKGROUND: Psoriasis was long regarded as an inflammatory disease limited to the skin. Data from dermatologic, rheumatologic and cardiologic research now show it to be a systemic disease, for which the term psoriatic disease is used. METHODS: This paper is based on a selective literature search with special attention to the findings of clinical trials and other current publications, as well as the recommendations of international guidelines. RESULTS: Immunologically mediated inflammation of the skin, arteries, bones, and joints is a central feature of psoriatic disease. Other diseases that are known to be associated with psoriatic disease include hypertension, metabolic syndrome, and depression. The main risk factor for the development of psoriatic disease is obesity, which also increases the likelihood of psoriatic arthritis. The main known trigger factors are stress, infection, and, less commonly, medication. Psoriatic disease is characterized by complex genetics and by a characteristic pattern of inflammation that involves elements of both innate and acquired immunity and, in particular, the cytokines interleukin 17 and 23. The inflammatory processes underlying psoriatic disease can now be targeted with modern biologic and other therapies. CONCLUSION: In view of the complexity of psoriatic disease, structured management is now recommended so that physicians and patients can work together to determine the optimal treatment strategy.

Impact of daily physical therapy over 2 weeks on spinal mobility including objective electronic measurements and function in patients with axial spondyloarthritis.

Background: Patients with axial spondyloarthritis (axSpA) are often compromised by impaired function and mobility. The standardized 2-week inpatient program 'multimodal rheumatologic complex treatment' (MRCT) was designed for patients with axSpA. The Epionics SPINE (ES) is an objective tool validated to assess mobility. Objective: To investigate the impact of MRCT on physical function and mobility including range of motion (RoM) and kinematics (RoK). Design: Single-center interventional, observational trial. Methods: Patients with axSpA presenting with high disease activity and impaired physical function were consecutively recruited to undergo MRCT. Assessments performed before (V1) and after (V2) the intervention included Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis functional index (BASFI), Bath Ankylosing Spondylitis Metrology Index (BASMI), the ankylosing spondylitis physical performance index (ASPI), the Short Physical Performance Battery (SPPB), and ES measurements. Results: At baseline, the 80 patients included had: BASDAI 5.5 ± 1.5, BASFI 5.6 ± 2.0, BASMI 4.2 ± 1.8, SPPB 13.8 ± 1.8, and ASPI 37.3 ± 18.1 s. Clinically relevant improvements between V1 versus V2 were noted for BASFI, BASMI, and all other assessments (p < 0.001), and also for ES measures of RoK (all p < 0.003) and RoM (all p < 0.04), while a positive trend was seen for flexion and extension (RoM). There was no significant effect of changes in medication (all p > 0.05). Conclusion: The 2-weeks MRCT was associated with definite improvements of function and mobility. Importantly, the effect of this extensive physical activity was confirmed by using the ES as an objective tool to assess spinal mobility. The ES demonstrated for the first time that the RoK of spinal mobility can significantly improve related to an exercise intervention. Trial registration: Ethical Committee: Ruhr-Universität (reference-number: 19-6735-BR).

Clinically relevant differences in spinal mobility related to daytime performance in patients with axial spondyloarthritis.

OBJECTIVE: Patients with axial spondyloarthritis (axSpA) suffer from clinical symptoms like morning stiffness and back pain. Mobility of patients with axSpA is often impaired. The aim of this study is to compare the performance of patients with axSpA regarding mobility measures including performance-based tests and objective electronic assessments with the Epionics SPINE device (ES) at different times of the day compared with healthy controls (HC). METHODS: Observational trial, consecutive inpatients with axSpA (n=100) and 20 HCs were examined in the morning (V1: before 10:00 am) and in the afternoon (V2: after 02:00 pm) by the Bath Ankylosing Spondylitis Metrology Index (BASMI), the AS physical performance index (ASPI), the Short Physical Performance Battery (SPPB) and ES measurements, including range of motion (RoM) and range of kinematics (RoK). RESULTS: The assessments of patients with axSpA performed in the morning clearly differed from those in the afternoon, especially regarding performance-based tests. Significant improvements were seen for BASMI (4.0±3.8 to 3.8±1.9; p<0.001), ASPI (36.2±18.3 to 28.8±11.9 s; p<0.001), SPPB (10.1±1.5 to 10.7±1.4 points; p<0.001) and for ES measures of speed (RoK; p<0.018) but not for RoM, except for lateral flexion (13.3±7.4 to 14.7±8.2°; p=0.002). This time of assessment-related variability was not observed in HC. CONCLUSION: The spinal mobility of patients with axSpA was worse in the morning but significantly improved in the afternoon. This was captured best by performance-based measures and was not seen in HC. The diurnal variation of mobility has implications for clinical studies, suggesting that the time of assessments needs to be standardised.

Population-based incidence of psoriasis vulgaris in Germany: analysis of national statutory insurance data from 65 million population.

Information on the population-based incidence of psoriasis vulgaris was limited. This study was to provide a comprehensive understanding of the age-specific and sex-specific incidence of psoriasis vulgaris in Germany. The data were obtained in the context of a morbidity-based risk adjustment by statutory health insurance companies in Germany, comprising information regarding 65 million population. Psoriasis vulgaris diagnoses were made and coded according to the 10th edition of the International Statistical Classification of Diseases and Related Health Problems. Age-specific and sex-specific incidences were calculated using data from 2009 to 2011. There was a rise in the age- and sex-specific incidences of psoriasis vulgaris through midlife, reaching a peak at the age of 60 and subsequently declining for both genders. The peak incidence for men, at 130 cases per 100,000 person-years, slightly exceeded the peak incidence for women of 117 per 100,000 person-years. An increase in the overall incidence rate can also be observed over the course of the three-year period covered by the data. Considerable variations in the age- and sex-specific incidences of psoriasis vulgaris can be seen across the lifespan. Nevertheless, the overall age-standardized incidence for the German population was low compared to other European countries.

High Frequency of Osteophytes Detected by High-Resolution Ultrasound at the Finger Joints of Asymptomatic Factory Workers.

Hand Osteoarthritis (HOA) is a frequently occurring musculoskeletal disease that impacts health. Diagnostic criteria often incorporate osteophytes documented through imaging procedures. Radiographic imaging is considered the gold standard; however, more sensitive and safer methods like ultrasound imaging are becoming increasingly important. We conducted a population-based cross-sectional study to examine the prevalence, grade, and pattern of osteophytes using high-resolution ultrasound investigation. Factory workers were recruited on-site for the study. Each participant had 26 finger joints examined using ultrasonography to grade the occurrence of osteophytes on a semi-quantitative scale ranging from 0-3, where higher scores indicate larger osteophytes. A total of 427 participants (mean age 53.5 years, range 20-79 years) were included, resulting in 11,000 joints scored. At least one osteophyte was found in 4546 out of 11,000 (41.3%) joints or in 426 out of 427 (99.8%) participants, but only 5.0% (553) of the joints showed grade 2 or 3 osteophytes. The total osteophyte sum score increased by 0.18 per year as age increased (p < 0.001). The distal interphalangeal joints were the most commonly affected, with 61%, followed by the proximal interphalangeal joints with 48%, carpometacarpal joint 1 with 39%, and metacarpophalangeal joints with 16%. There was no observed impact of gender or workload. In conclusion, ultrasound imaging proves to be a practical screening tool for osteophytes and HOA. Grade 1 osteophytes are often detected in the working population through ultrasound assessments and their incidence increases with age. The occurrence of grade 2 or 3 osteophytes is less frequent and indicates the clinical presence of HOA. Subsequent evaluations are imperative to ascertain the predictive significance of early osteophytes.

A population-based projection of psoriatic arthritis in Germany until 2050: analysis of national statutory health insurance data of 65 million German population.

The population-based prevalence of psoriatic arthritis (PsA) is still unclear and not well described globally. The aim of this study was to conduct a population-based prevalence projection and provide long-term future estimations of PsA patients in Germany until 2050, using the illness-death model and based on historical data. We analyzed the national statutory health insurance data of 65 million population in the German Institute for Medical Documentation and Information between January 2009 and December 2012. We constructed an estimation of the PsA burden among the German population using the relevant epidemiological parameters to project the numbers of patients with PsA in Germany until 2050 under five possible scenarios by varying the incidence and mortality. The overall conservatively estimated prevalence of PsA in Germany in 2019 was 0.31% (95% CI 0.28-0.36%). Women contribute a higher prevalence than men in all five scenarios. In the assumed scenarios with increased incidence, the prevalence of PsA at 60 years of age could rise from 1% in 2019 to more than 3% in 2050 for both genders, with the increase particularly pronounced for women, reaching around 3.5%. However, in the assumed scenarios with decreasing incidence, the prevalence curve may flatten and begin a decreasing trend from 2035 to 2050 for both genders, achieving a prevalence of less than 1% in 2050. Our research is to generate assumed population-based data on PsA in Germany that can serve as a reference for public health stakeholders to prepare an optional intervention. We would expect worryingly high numbers in the coming decades if preventive strategies are not implemented. In the long term, it will be necessary to implement preventive strategies to identify predictors and treat psoriasis symptoms early in order to delay or even prevent the transition of psoriasis to PsA.

'Status Quo' on Different Aspects of Gender Distribution in Rheumatology in Germany-Results from a Nationwide Online Survey among Physicians.

OBJECTIVES: Despite the increasing number of female medical students and fellows in Europe, women are still under-represented in higher academic careers and positions in medicine. The aim of this survey was to assess the 'status quo' on gender distribution among rheumatologists in Germany. METHODS: A web-based anonymous survey (21 questions with multiple answers and free text) using QuestionPro® was distributed among rheumatologists in Germany via newsletters, social media and personal contact, including questions regarding hierarchical positions and work characteristics. RESULTS: Among the total of 170 respondents (72% women, 28% men, 1% diverse), 48% were rheumatologists in training, 35% were trained rheumatologists and 7% were heads of rheumatology departments. Regarding the gender ratio at different hierarchical levels, 74% of respondents reported more men than women in leadership positions. Part-time work was possible in the departments of 86% of respondents, with more women working part-time (56%) compared to men (29%). Most respondents stated their impression that employees working part-time did not have the same career chances as full-time workers in their departments. In total, 66% agreed that activities to improve gender equity are necessary. The highest need was seen in reconciling work and family through, e.g., part-time models, flexible childcare options at work and a higher acceptance of part-time work in leadership positions. CONCLUSIONS: According to our results, a gender imbalance is prevalent among rheumatologists in Germany, with lower numbers of women evident at higher hierarchical levels. Traditional role assignments are still represented by a higher proportion of part-time work in women. The establishment of structural changes to achieve better gender equity is needed.

Addressing the spread of health-related misinformation on social networks: an opinion article.

This article deals with the spread of misinformation in a general context and specifically in the health sector. It presents a theoretical view of the problem and analyzes its characteristics with a focus on medicine and mainly rheumatology. Finally, conclusions from the previous analysis are formulated as well as suggestions for reducing the dimensions of the problem in the health sector.

Patients' awareness towards physical activity in the treatment of axial spondyloarthritis.

INTRODUCTION: The course of axial spondyloarthritis (axSpA) is often characterized by impairments in physical function and mobility. Regular physical activity (PA) is a cornerstone of axSpA management. Recent European League Against Rheumatism (EULAR) recommendations for PA have stressed the importance of their implementation. OBJECTIVE: Cohort study to investigate the awareness on and individual implementation of axSpA patients towards PA. METHODS: Patients with axSpA and impaired physical function (Bath AS Functional Index [BASFI] score≥2.0) were recruited consecutively. All patients underwent a clinical examination including assessments of disease activity, physical function, mobility and global functioning. Patients also had to fill out structured questionnaires on knowledge, awareness and individual attitudes to PA. RESULTS: Out of a total of 100 patients enrolled, 96 were included. Most respondents (n=82, 85.4%) were aware that PA has significant health benefits for patients with axSpA. Even though less than half of the patients (n=44, 42.7%) were aware that actual EULAR recommendations do exist, 45 patients (46.9%) did already fulfill these in terms of frequency/week. The majority of patients (n=61, 67.7%) had been informed about the benefits of PA by their physician, and physiotherapy had often been prescribed (n=61, 63.3%). Many patients (n=51, 53.1%) reported to perform individual exercise programs, and some (n=22, 22.9) supervised PA. CONCLUSION: Even though the majority of axSpA patients are not aware of the recent EULAR recommendations for PA, many understand and agree that PA is beneficial for their health status. Health care providers should concentrate on the patients who are not active and do not know about the benefits of PA.

Proof-of-Concept Double-Blind Placebo-Controlled Trial Measuring Cartilage Composition in Early Rheumatoid Arthritis under TNF-α-Inhibitor Therapy.

Low levels of delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) values are indicative of cartilage degeneration. Patients with early rheumatoid arthritis are known to have low dGEMRIC values due to inflammatory activity. The additional effect of biological disease-modifying antirheumatic drug (bDMARD) and conventional synthetic disease-modifying antirheumatic drug (csDMARD) treatment on cartilage status is still unclear. In this prospective, double-blinded, randomized proof-of-concept clinical trial, patients with early rheumatoid arthritis (disease duration less than 12 months from symptoms onset) were treated with methotrexate + adalimumab (10 patients: 6/4 (f/m)). A control group with methotrexate alone (four patients: 2/2 (f/m)) was used. Cartilage integrity in the metacarpophalangeal joints was compared using dGEMRIC at baseline, 12, and 24 weeks after treatment initiation. A statistically significant increase in dGEMRIC levels was found in the adalimumab group considering the results after 12 and 24 weeks of therapy (p < 0.05) but not in the control group (p: non-significant). After 24 weeks, a tendency towards increased dGEMRIC values under combination therapy was observed, whereas methotrexate alone showed a slight decrease without meeting the criteria of significance (dGEMRIC mean change: +85.8 ms [-156.2-+346.5 ms] vs. 30.75 ms [-273.0-+131.0 ms]; p: non-significant). After 24 weeks of treatment with a combination of methotrexate and adalimumab, a trend indicating improvement in cartilage composition is seen in patients with early rheumatoid arthritis. However, treatment with methotrexate alone showed no change in cartilage composition, as observed in dGEMRIC sequences of metacarpophalangeal joints.

[Practicable diagnostics of Sjögren's syndrome in interstitial lung disease-A discussion article]. / Praktikable Sjögren-Diagnostik bei interstitieller Lungenerkrankung ­ ein Diskussionsbeitrag.

Sjögren's syndrome (SjS) is a possible autoimmune cause of interstitial lung disease. The diagnostic pathway for SjS, however, is largely undefined in comparison to other systemic autoimmune diseases. Subjective sicca symptoms, anti-SS-A/Ro antibodies and even ANA as screening tests all have relevant limitations in sensitivity and/or specificity. Against this background, in an interdisciplinary discussion we have developed a consensus for the clarification of SjS, which is presented here for broader discussion. In addition to ANA and anti-SS-A/Ro antibodies, antibodies against alpha-fodrin should be included. Objective measures of dryness, such a Schirmer and Saxon tests are important, as is a salivary gland biopsy in the absence of typical autoantibodies.

[Acceptance of video consultation among patients with inflammatory rheumatic diseases depends on gender and location-Results of an online survey among patients and physicians]. / Akzeptanz der Videosprechstunde unter Patienten/innen mit entzündlich rheumatischen Erkrankungen ist geschlechts- und ortsabhängig ­ Ergebnisse einer Online-Umfrage unter Patienten/innen und Ärzten/innen.

INTRODUCTION: In order to successfully integrate telemedicine into the daily routine of rheumatology, both the patient's and the physician's perspective are important. For this purpose, a detailed study by means of a web-based survey was conducted by the Working Group Young Rheumatology (AGJR) of the German Society for Rheumatology (DGRh) and the German Rheumatism League National Association. By means of subgroup analysis of the data regarding video consultation, the aim was now to find out which requirements and wishes patients and physicians have for video consultations. METHODS: The prospective survey was distributed via social media, QR code and email. Descriptive statistics and regression analysis related to video consultation were performed and correlations were shown. RESULTS: The data indicated positive attitudes toward video consultation on the part of both patients (n = 299) and rheumatologists (n = 129). A correlation between age and positive opinion of the video consultation was found among the patients (r = 0.161, p = 0.006), especially among female patients a positive approval of the video consultation was found with increasing age (r = 0.244, p < 0.001 to male patients: r = -0.190, p = 0.145). Regarding the travelling time to the treating rheumatologist, male patients found the video consultation more attractive with increasing travelling time (r = 0.229, p = 0.078). With respect to the wishes of patients and physicians, video consultation should be used primarily for follow-up or emergency appointments. Video consultation for initial appointments, on the other hand, was very rarely mentioned. CONCLUSION: During the COVID 19 pandemic, video consultation was increasingly popular among rheumatology patients as well as among rheumatologists.

Management of Dactylitis in Patients With Psoriatic Arthritis: An Updated Literature Review Informing the 2021 GRAPPA Treatment Recommendations.

OBJECTIVE: This literature review aimed to identify the most efficacious current interventions for dactylitis and provide up-to-date scientific evidence to support the 2021 Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) recommendations on the management of psoriatic arthritis. METHODS: Original articles published from 2013 to 2020, registered in MEDLINE, Embase, and Cochrane Library, describing interventional trials and reporting dactylitis-related outcomes were included. The 20 members of the GRAPPA dactylitis group were divided into 9 subgroups according to treatment, and members of each group independently extracted data from articles/abstracts corresponding to their group by using a standardized data extraction form. RESULTS: Forty-nine publications were analyzed, representing 40 randomized clinical trials (RCTs) and including 16,752 patients. Dactylitis was assessed as a secondary outcome in 97.5% of these trials and more than 40% of RCTs did not employ a specific dactylitis measure or instrument. CONCLUSION: The emergence of agents with novel mechanisms of action in recent years, such as interleukin 17 (IL-17), IL-12/23, IL-23, and Janus kinase inhibitors, has significantly expanded the available treatment options for dactylitis. This article points out the lack of consensus regarding dactylitis assessment and the paucity of data concerning the effect of local steroid injections, nonsteroidal antiinflammatory drugs, and conventional disease-modifying antirheumatic drugs. Clinical trials evaluating the effect of these traditional and low-cost medications used to treat dactylitis should be encouraged.

Perioperative management of patients with inflammatory rheumatic diseases : Updated recommendations of the German Society for Rheumatology.

BACKGROUND: Prior to surgical interventions physicians and patients with inflammatory rheumatic diseases remain concerned about interrupting or continuing anti-inflammatory medication. For this reason, the German Society for Rheumatology has updated its recommendations from 2014. METHODS: After a systematic literature search including publications up to 31 August 2021, the recommendations on the use of of glucocorticoids, conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and biologics (bDMARDs) were revised and recommendations on newer drugs and targeted synthetic (ts)DMARDs were added. RESULTS: The glucocorticoid dose should be reduced to as low as possible 2-3 months before elective surgery (in any case <10 mg/day) but should be kept stable 1-2 weeks before and on the day of surgery. In many cases csDMARDs can be continued, exceptions being a reduction of high methotrexate doses to ≤15 mg/week and wash-out of leflunomide if there is a high risk of infection. Azathioprine, mycophenolate and ciclosporin should be paused 1-2 days prior to surgery. Under bDMARDs surgery can be scheduled for the end of each treatment interval. For major interventions Janus kinase (JAK) inhibitors should be paused for 3-4 days. Apremilast can be continued. If interruption is necessary, treatment should be restarted as soon as possible for all substances, depending on wound healing. CONCLUSION: Whether bDMARDs increase the perioperative risk of infection and the benefits and risks of discontinuation remain unclear based on the currently available evidence. To minimize the risk of a disease relapse under longer treatment pauses, in the updated recommendations the perioperative interruption of bDMARDs was reduced from at least two half-lives to one treatment interval.

Evaluation of Sodium Relaxation Times and Concentrations in the Achilles Tendon Using MRI.

Sodium magnetic resonance imaging (MRI) can be used to evaluate the change in the proteoglycan content in Achilles tendons (ATs) of patients with different AT pathologies by measuring the 23Na signal-to-noise ratio (SNR). As 23Na SNR alone is difficult to compare between different studies, because of the high influence of hardware configurations and sequence settings on the SNR, we further set out to measure the apparent tissue sodium content (aTSC) in the AT as a better comparable parameter. Ten healthy controls and one patient with tendinopathy in the AT were examined using a clinical 3 Tesla (T) MRI scanner in conjunction with a dual tuned 1H/23Na surface coil to measure 23Na SNR and aTSC in their ATs. 23Na T1 and T2* of the AT were also measured for three controls to correct for different relaxation behavior. The results were as follows: 23Na SNR = 11.7 ± 2.2, aTSC = 82.2 ± 13.9 mM, 23Na T1 = 20.4 ± 2.4 ms, 23Na T2s* = 1.4 ± 0.4 ms, and 23Na T2l* = 13.9 ± 0.8 ms for the whole AT of healthy controls with significant regional differences. These are the first reported aTSCs and 23Na relaxation times for the AT using sodium MRI and may serve for future comparability in different studies regarding examinations of diseased ATs with sodium MRI.

To Contrast or Not to Contrast? On the Role of Contrast Enhancement in Hand MRI Studies of Patients with Rheumatoid Arthritis.

Currently, clinical indications for the application of gadolinium-based contrast agents (GBCA) in magnetic resonance imaging (MRI) are increasingly being questioned. Consequently, this study aimed to evaluate the additional diagnostic value of contrast enhancement in MRI of the hand in patients with rheumatoid arthritis (RA). Thirty-one patients with RA (mean age, 50 ± 14 years (range, 18-72 years)) underwent morphologic MRI scans on a clinical 3 T scanner. MRI studies were analyzed based on (1) the Rheumatoid Arthritis Magnetic Resonance Imaging Score (RAMRIS) and (2) the GBCA-free RAMRIS version, termed RAMRIS Sine-Gadolinium-For-Experts (RAMRIS-SAFE), in which synovitis and tenosynovitis were assessed using the short-tau inversion-recovery sequence instead of the post-contrast T1-weighted sequence. The synovitis subscores in terms of Spearman's ρ, as based on RAMRIS and RAMRIS-SAFE, were almost perfect (ρ = 0.937; p < 0.001), while the tenosynovitis subscores were less strongly correlated (ρ = 0.380 p = 0.035). Correlation between the total RAMRIS and RAMRIS-SAFE was also almost perfect (ρ = 0.976; p < 0.001). Inter-rater reliability in terms of Cohen's κ was high (0.963 ≤ κ ≤ 0.925). In conclusion, RAMRIS-SAFE as the GBCA-free version of the well-established RAMRIS is a patient-friendly and resource-efficient alternative for assessing disease-related joint changes in RA. As patients with RA are subject to repetitive GBCA applications, non-contrast imaging protocols should be considered.
