Defining the physician global assessment threshold equivalent to remission in patients with systemic lupus erythematosus.

OBJECTIVES: The optimal threshold of the physician global assessment (PGA) for remission in SLE has never been evaluated systematically. The aim of this study was to assess the ideal PGA threshold associated with physician remission and to investigate its impact on remission rates in our Lupus cohort. METHODS: In this monocentric cross-sectional study, patients with SLE were evaluated for physician remission by asking the treating physicians if they considered their patient in remission regardless of objective remission criteria. Further, two objective remission definitions were applied: 1) DORIS remission using a PGA of < 2 (0-10) (corresponding to < 0.5 on a VAS 0-3 used in DORIS); 2) DORIS remission with omission of PGA (modDORIS). A receiver operating characteristic analysis and regression analyses were performed to assess the ideal PGA threshold and factors influencing PGA. RESULTS: Of the 233 patients included, 126 patients (54.0%) were in physician remission, 42.5% in DORIS remission and 67.0% in modDORIS remission. A PGA of < 2 NRS 0-10) had the highest sensitivity (79%) and specificity (81%) for physician remission and modDORIS (AUC 0.85 and 0.69). PGA of patients fulfilling any of the remission definitions was associated with pain and hypocomplementemia. Damage was numerically higher in patients in modDORIS only; no association between PGA and damage was found in regression analysis. CONCLUSION: Using a PGA threshold of < 2 (0-10), corresponding to < 0.6 (0-3) resulted in best prediction of physician remission. PGA levels seem to be influenced by pain and complement levels but not disease damage.

Beneficial effects associated to a healthy lifestyle in systemic lupus erythematosus: A cross-sectional study.

OBJECTIVE: To assess whether a healthy lifestyle is associated to beneficial effects on various systemic lupus erythematosus (SLE) health domains. METHODS: In a cross-sectional study, Mediterranean Diet Adherence Score (MEDAS), physical activity energy expenditure (PAEE), and smoking status were assessed by questionnaires, along with clinical parameters and various health domains including Systemic Lupus Disease Activity Score (SLEDAI), Depression Scale (CES-D), Fatigue Severity (FSS), functional status (FFbH), physical and mental quality of life (PCS, MCS). Lifestyle choices were assessed with respect to health domains by linear regression modeling. Additionally, SLE patients with a healthy lifestyle (MEDAS ≥ 4, ≥ 1 h sport per week, no smoking) were compared to those without by Wilcoxon's signed-rank test. RESULTS: 49 of 145 SLE patients (44.3 ± 31.7 years, 87.6% female) followed a healthy lifestyle and showed a higher physical quality of life (ß = 4.5 (95%-CI 1.5-7.9) p = 0.01), lower depression (ß = -5.0 (-8.2 to -0.2) p = 0.02) and lower fatigue (ß = -0.8 (-1.5 to -0.2) p = 0.01) independently of SLE disease activity. Furthermore, dsDNA-antibodies were lower (146 ± 540 vs 266 ± 146 U/mL, p = 0.049). In a more detailed analysis, physical activity had the highest impact on the various health domains when compared to smoking or diet adherence, which was consistent even after adjusting for multiple potential confounders. Each 1,000 kcal of weekly PAEE was associated to a 1.8 (0.9-2.6) point increase in the PCS (p = 0.0001), a 0.2 (0.03-0.4) point decrease in the CES-D (p = 0.01) and a 2.8 (1.2-4.4) point increase in the FFbH (p = 0.0006). CONCLUSION: A healthy lifestyle, especially physical activity is associated with beneficial effects including quality of life, depression and fatigue in SLE.

Time interval between the onset of connective tissue disease symptoms and first contact with a rheumatologist: results from the German National Database of collaborative arthritis centers.

The long-term outcome of connective tissue diseases is associated with the time from symptom onset to diagnosis. To understand gaps in care, we determine whether the length of time between symptom onset and first presentation to a rheumatologist has changed in Germany in recent decades. We analyzed data on patients diagnosed with connective tissue diseases (n = 19,662) collected from the German National Database of the Regional Cooperative Rheumatology Centers. We reviewed the onset of relevant symptoms listed at first presentations from 1993 to 2018 and performed a quantitative analysis of the intervals until first presentation to a rheumatologist. We compared time intervals and performed a linear mixed regression model with random effects to identify associated factors. Although the interval between the onset of symptoms and first presentation to a rheumatologist has diminished since 1980 for all connective tissue diseases, there has been no relevant improvement during the past 2 decades. The interval between symptoms and presentation increases with patients age for all connective tissue diseases (e.g., Systemic sclerosis; for each 10-year-increment of patients age: ß 0.41, CI 0.38; 0.44). Among those diagnosed with systemic sclerosis, the mean interval was 1.5 years (95% CI 1.1; 1.8) for male patients and 2.6 years (95% CI 2.4; 2.8) for females. Patients presenting with different degrees of disease severity on their first visits and with different educational levels had similar mean intervals between symptoms and first presentation regardless of their final diagnoses. Over the past 2 decades, the time to first consultation with a rheumatologist has not continued to improve in Germany, but has stagnated at the same level. Selected patient subgroups, such as older patients with suspected connective tissue diseases and female patients with suspected systemic sclerosis, are at risk to present late and may in particular benefit from an earlier referral to a rheumatologist.

Digitalization and disruptive change in rheumatology.

INTRODUCTION: Recently, many sectors have seen disruptive changes due to the rapid progress in information and communication technology (ICT). The aim of this systematic literature review was to develop a first understanding of what is known about new ICTs in rheumatology and their disruptive potential. METHODS: PubMed, LIVIVO, and EBSCO Discovery Service (EDS) databases were searched for relevant literature. Use of new ICTs was identified, categorized, and disruptive potential was discussed. Articles from 2008 to 2021 in German and English were considered. RESULTS: A total of 3539 articles were identified. After application of inclusion/exclusion criteria, 55 articles were included in the analyses. The majority of articles (48) used a non-experimental design or detailed expert opinion. The new ICTs mentioned in these articles could be allocated to four main categories: technologies that prepare for the development of new knowledge by data collection (n = 32); technologies that develop new knowledge by evaluation of data (e.g., by inventing better treatment; n = 11); technologies that improve communication of existing knowledge (n = 32); and technologies that improve the care process (n = 29). Further assessment classified the ICTs into different functional subcategories. Based on these categories it is possible to estimate the disruptive potential of new ICTs. CONCLUSION: ICTs are becoming increasingly important in rheumatology and may impact patients' lives and professional conduct. The properties and disruptive potential of technologies identified in the articles differ widely. When looking into ICTs, doctors have focused on new diagnostic and therapeutic procedures but rarely on their disruptive potential. We recommend putting more effort into investigation of whether ICTs change the way rheumatology is performed and who is in control of it. Especially technologies that potentially replace physicians with machines, take control over the definition of quality in medicine, and/or create proprietary knowledge that is not accessible for doctors need more research.

Off-label use of mycophenolate mofetil in the treatment of rare and complex rheumatic connective tissue diseases.

OBJECTIVES: We aimed to investigate the clinical off-label use of mycophenolate mofetil (MMF), including its safety and efficacy in patients with rare and complex rheumatic connective tissue diseases (rCTDs). METHODS: A survey was distributed across experts from ERN-ReCONNET reference centres in order to assess the experience with MMF off-label use. Patient-level data of patients with rCTDs under treatment with MMF was also collected for analysis of safety and efficacy. RESULTS: Twelve experts from eleven centres distributed throughout Europe (7 countries) answered the survey. The experience was concordant in that, despite of its off-label use, experts reported opting frequently for this therapeutic alternative with robust confidence on its efficacy and safety. The analysis of 108 patients with rCTDs under MMF revealed a good safety profile, as well as good clinical outcomes, especially for systemic lupus erythematosus and idiopathic inflammatory myopathies. The presence of interstitial lung disease was, as expected, associated with a worse clinical outcome despite use of MMF. CONCLUSIONS: MMF is widely used in reference centres for rCTDs. Its safety profile and efficacy seem to be recognised by experts and demonstrated with patient-level analysis. While selected rCTDs will likely remain an off-label indication for MMF, robust data seem to support this therapy as an appropriate alternative for safely and effectively treating many manifestations of rCTDs.

Remission in SLE-do DORIS criteria match the treating physician's judgment? A cross-sectional study to assess reasons for discordance.

OBJECTIVES: The definition of an accurate target for a treat-to-target approach in SLE has been challenging over past years, and recently the DORIS definitions of remission were presented by the international DORIS task force. It was our aim to assess the frequency of DORIS remission and LLDAS in our SLE cohort and their agreement with the treating physician's (DORIS-) independent remission judgement. Patient characteristics leading to lack of agreement and incoherence ought to be identified. METHODS: In this monocentric cross-sectional study, patients with SLE were enrolled and assessed between September 2016 and December 2017. DORIS remission definitions were applied and after the clinical consultation, the treating physicians gave his/her opinion on whether the patient was in remission. Regression analyses were performed to identify parameters influencing physician remission. RESULTS: A total of 233 patients were included (87.6% female); 99 (42.5%) patients fulfilled any of the four DORIS remission definitions, while 126 patients were in remission according to their physician's judgement. We observed discordance in the assessment of remission in 53 patients (22.7%). Physician remission was influenced by disease activity [odds ratio (OR) 0.76, 95% CI: 0.63, 0.90], disease and/or treatment-related damage (OR 0.78, 95% CI: 0.62, 0.98) and the presence of ds-DNA antibodies (OR 2.47, 95% CI: 1.06, 6.04). CONCLUSIONS: DORIS remission proved an achievable target in our outpatient clinic. Still we found discordance regarding DORIS remission and the treating physician's judgement with a greater number of patients considered in remission by their physicians.

Factors detrimental to work productivity and daily activities in systemic lupus erythematosus patients - Analysis of the German LuLa study.

OBJECTIVE: The aim of this study was to identify factors associated with impaired work productivity and impaired daily activities in patients with systemic lupus erythematosus (SLE). METHODS: The LuLa study is a longitudinal patient-reported study. Beyond sociodemographic data, work productivity, daily activities and fatigue, several other clinical outcome parameters (e.g. mental health-related quality of life and physical functioning, disease activity, damage and pain) were surveyed with validated questionnaires. The effects of confounders on work productivity (WPAI 2) and daily activity domains (WPAI 4) were studied by multivariate regression analysis. RESULTS: A total of 585 patients completed the questionnaire of whom 259 were employed and analysed. The median impairment in work productivity (WPAI 2) was 20% (Q1-3 0-40), and the median impairment in daily activities (WPAI 4) was 30% (Q1-3 10-50%). Multivariate regression analysis revealed that fatigue, pain, disease activity and health-related quality of life affected WPAI 2 and 4. Furthermore, we observed distinct synergistic effects of fatigue, disease activity and pain on both work productivity and daily activities: a higher impact of fatigue was associated with the reported extent of pain or disease activity. CONCLUSION: In employed patients with SLE, impaired work productivity and impaired daily activities were frequently reported. Fatigue, pain, disease activity and health-related quality of life demonstrated a detrimental impact, with a synergistic effect of fatigue, disease activity and pain. Hence, both optimized pain management and targeted immunomodulatory therapy are important for preserving active participation in life among patients with fatigue.

Delayed diagnosis adversely affects outcome in systemic lupus erythematosus: Cross sectional analysis of the LuLa cohort.

OBJECTIVE: Despite increased physician's awareness and improved diagnostic and serological testing in the recent years, the interval between the initial symptoms and the diagnosis of Systemic lupus erythematosus (SLE) is still very long. Our aim was to study this delay and its association to the outcome of the disease. METHODS: Information on demographics, onset of first symptoms, first physicians visit and time of diagnosis was assessed by self-reported questionnaires among SLE patients in Germany (LuLa cohort, n = 585) in the year 2012. Disease activity (Systemic Lupus Activity Questionnaire; SLAQ), disease related damage (Brief Index of Lupus Damage; BILD), health related quality of life (Short Form 12) and fatigue (FSS) were chosen as proxies for outcome. Linear regression analysis was used to analyze the association of the delay in diagnosis to the outcome, adjusted for age, disease duration and sex. RESULTS: Mean duration between the onset of symptoms and the diagnosis of SLE was 47 months (SD 73). The longer the time to diagnosis, the higher the disease activity (ß = 0.199, p < 0.0001), the disease-related damage (ß = 0.137, p = 0.002) and fatigue (ß 0.145, p = 0.003) and the lower the health-related quality of life (physical ß = -0.136, p = 0.004, mental ß = -0.143, p = 0.004). CONCLUSION: In systemic lupus erythematosus, longer time to diagnosis was associated with worse outcome. Concepts in care with the intention to shorten the time to diagnosis are needed to improve the long-term outcome of the disease.

Associations of site-specific CD4+-T-cell hypomethylation within CD40-ligand promotor and enhancer regions with disease activity of women with systemic lupus erythematosus.

OBJECTIVE: To comprehensively assess associations of site-specific CD4+-T-cell hypomethylation of the CD40-Ligand gene (CD40L) with disease activity of women with systemic lupus erythematosus (SLE). METHODS: CpG-sites within the DNA of the promotor and two enhancer regions (n = 22) of CD40L were identified and numbered consecutively. The rate of methylated DNA in isolated CD4+-T-cells of women with SLE were quantified for each methylation site by MALDI-TOF. Disease activity was assessed by SLE Disease Activity Index (SLEDAI). Associations of site-specific methylation rates with the SLEDAI scores were assessed by linear regression modelling. P values were adjusted according to Bonferroni-Holm as indicated. RESULTS: 60 female SLE patients participated in the study (age 45.7 ± 11.1 years, disease duration 17.0 ± 8.3 years). Significant associations to the SLEDAI were noted for CpG22 hypomethylation of the promotor (ß = -40.1, p = 0.017, adjusted p = 0.027), trends were noted for CpG17 hypomethylation of the promotor (ß = -30.5, p = 0.032, adjusted p = 0.6), and for CpG11 hypermethylation of the second enhancer (ß = 15.0, p = 0.046, adjusted p = 0.8). CONCLUSION: Site-specific hypomethylation of the CD40L promotor in CD4+-T-cells show associations with disease activity in female SLE patients.

Methyl donor micronutrients, CD40-ligand methylation and disease activity in systemic lupus erythematosus: A cross-sectional association study.

OBJECTIVE: Hypomethylation of CD40-ligand (CD40L) in T-cells is associated with increased disease activity in systemic lupus erythematosus (SLE). We therefore investigated possible associations of dietary methyl donors and products with CD40L methylation status in SLE. METHODS: Food frequency questionnaires were employed to calculate methyl donor micronutrients in 61 female SLE patients (age 45.7 ± 12.0 years, disease duration 16.2 ± 8.4 years) and compared to methylation levels of previously identified key DNA methylation sites (CpG17 and CpG22) within CD40L promotor of T-cells using quantitative DNA methylation analysis on the EpiTYPER mass spectrometry platform. Disease activity was assessed by SLE Disease Activity Index (SLEDAI). Linear regression modelling was used. P values were adjusted according to Benjamini & Hochberg. RESULTS: Amongst the micronutrients assessed (g per day), methionine and cysteine were associated with methylation of CpG17 (ß = 5.0 (95%CI: 0.6-9.4), p = 0.04; and ß = 2.4 (0.6-4.1), p = 0.02, respectively). Methionine, choline, and cysteine were additionally associated with the mean methylation of the entire CD40L (ß = 9.5 (1.0-18.0), p = 0.04; ß = 1.6 (0.4-3.0), p = 0.04; and ß = 4.3 (0.9-7.7), p = 0.02, respectively). Associations of the SLEDAI with hypomethylation were confirmed for CpG17 (ß=-32.6 (-60.6 to -4.6), p = 0.04) and CpG22 (ß=-38.3 (-61.2 to -15.4), p = 0.004), but not the mean methylation of CD40L. Dietary products with the highest impact on methylation included meat, ice cream, white bread, and cooked potatoes. CONCLUSIONS: Dietary methyl donors may influence DNA methylation levels and thereby disease activity in SLE.

[Annual meeting of the German Society for Rheumatology going virtual-successfully defying the pandemic]. / Deutscher Rheumatologiekongress virtuell ­ erfolgreich tagen trotz Pandemie.

BACKGROUND: In 2020 the COVID-19 pandemic led to the annual meeting of the German Society for Rheumatology (DGRh) being conducted as the virtual German Rheumatology Congress. AIM: How is the virtual German Rheumatology Congress accepted and what are the possibilities of optimization for the future? MATERIAL AND METHOD: The registered participants were asked to take part in an online congress evaluation. RESULTS: Of 2566 congress attendees, 721 participated in the evaluation. The majority (80.2%) were (very) satisfied with the event overall. Compared to the traditional format collegial exchange was perceived as worse using the virtual approach. The technology platform was predominantly described as easy to use and easily accessible. The selected topics of the congress met the expectations of 89% of the participants. The presented contents were estimated to be relevant for their professional activities by 85.2% of the participants. The majority of participants (85.3%) would welcome the congress contents to be permanently available on demand. DISCUSSION: Overall, the participants appreciated the virtual format of the German Rheumatology Congress. Optimization aspects could be shown and these could be considered in the implementation of further (digital) congresses. The results of this work provide suggestions for improvement on how the DGRh can meet and exceed the needs of participants in organizing a virtual or hybrid conference in the future.

The patient's perspective: are quality of life and disease burden a possible treatment target in systemic lupus erythematosus?

A few decades ago, the therapy goal of patients with systemic lupus erythematosus (SLE) was survival and the prevention of organ failure. Today, clinical remission and low disease activity are believed to be the optimal therapeutic targets. These aims are difficult to reach for many patients, but they still do not address the health-related quality of life (QoL) that is significantly impaired in SLE patients. Even in the state of remission, QoL and fatigue are insufficient controlled. Thus, patient-oriented research is essential to design new strategies for the management of lupus patients. The INTEGRATE project analyses the patients' and physicians' perspectives to pave the way to design an innovative therapeutic strategy for lupus and focuses on the multifaceted dimensions of the disease burden. Shared decision making (SDM) could include the patient's perspective of SLE to treatment strategy and consider QoL and the burden of lupus into the process of therapy decision.

Vaccination coverage in systemic lupus erythematosus-a cross-sectional analysis of the German long-term study (LuLa cohort).

OBJECTIVES: Vaccinations are an important measure to prevent infections in immunocompromised patients. The knowledge of vaccination coverage and reasons for non-vaccination in patients with SLE is scarce. The aim of this study was to assess coverage rates of selected vaccinations in a representative sample of SLE patients and to identify predictors for non-vaccination. METHODS: In 2013, information on selected vaccinations (coverage, application and reservations) and on demographics, clinical parameters and health beliefs was assessed by means of a self-reported questionnaire among a representative sample of SLE patients in Germany (LuLa cohort). RESULTS: Five hundred and seventy-nine patients participated. Vaccination status was primarily checked by their general practitioner (57.3%). Of all the patients, 24.9% did not get their vaccination status checked at all, 16.1% had generally been advised against the use of vaccinations by a physician, and 37.5% stated that they had rejected vaccinations themselves. Their main reasons were fears of developing a lupus flare (21.8%) or adverse events (13.5%). A greater belief by patients in the doctor controlling one's health and the general benefit of medication prevented the rejection of vaccines. Vaccination coverage was low for all recorded vaccinations (tetanus 65.8%, influenza 45.2%, pneumococcus 32.2% and meningococcus 6.1%). Older age was predictive of receiving influenza and pneumococcal vaccination. The same applies for CSs >7.5 mg for receiving influenza vaccination. CONCLUSION: Vaccination coverage in SLE patients is poor and reflects insufficient implementation of national and international recommendations. Rheumatologists need to recognize patients' reservations against vaccinations, to communicate their importance and safety and to give individual recommendations to patients and their health-care providers.

Electronic health records in rheumatology: emphasis on automated scoring and additional use.

Electronic health records are increasingly used and frequently required from various regulatory authorities. Apart from their day-to-day use by health care professionals for routine clinical practice and/or the improvement of quality of care processes, patients with chronic inflammatory disease may become increasingly involved in the data retrieval process by self-monitoring and providing patient-reported (outcome) data. Among key features of electronic health records are automated scoring, visualisation of validated measures, and long-term systematic patient-centered data collection in a structured and standardised manner. Data derived from electronic health records are increasingly incorporated into patient-centered research, registries, and other secondary uses. Thus, electronic health records offer opportunities to improve knowledge and to create new process flows in rheumatology health care. The article summarises some of these opportunities in patient care, as well as an overview of secondary use scenarios. In addition, the article focuses on patients' active involvement in the disease management process via health information applications, reports on patients' perspectives, as well as some legal and regulatory matters concerning electronic health records.
