Applications to augment patient care for Internal Medicine specialists: a position paper from the EFIM working group on telemedicine, innovative technologies & digital health.

Telemedicine applications present virtually limitless prospects for innovating and enhancing established and new models of patient care in the field of Internal Medicine. Although there is a wide range of innovative technological solutions in Europe, there are overarching elements associated with such technologies when applied to the practices of Internal Medicine specialists. The European Federation of Internal Medicine (EFIM) strongly advocates for active leadership and influence from the Internal Medicine societies and specialist physicians across Europe in the development and application of telemedicine and digital technologies in healthcare. This position paper's conclusions were drawn via Delphi method, which was developed collaboratively from July 2021 to December 2023. The panel, consisting of experts in clinical medicine, public health, health economics and statistics, assessed various aspects related to telemedicine. Participants assigned scores on a Likert scale reflecting perceived value and potential risks. The findings were consolidated in a comprehensive checklist aligning with relevant literature and a SWOT analysis. Specifically, key issues that need to be addressed include promoting the professional development of e-health competencies in the healthcare and medical workforce, using educational campaigns to promote digital literacy among patients and caregivers, designing and implementing telemedicine applications tailored to local conditions and needs and considering the ethical and legal contexts under which these applications are employed. Importantly, there is currently no consensus on care models or standardized protocols among European Internal Medicine specialists regarding the utilization of telemedicine. This position paper aims to outline the opportunities and challenges associated with the application of telemedicine in Internal Medical practice in Europe.

Induction of cross-reactive, mucosal anti-SARS-CoV-2 antibody responses in rheumatoid arthritis patients after 3rd dose of COVID-19 vaccination.

Systemic vaccination against SARS-CoV-2 elicited high titers of specific antibodies in the blood and in the oral cavity. Preexisting autoimmune diseases, such as rheumatoid arthritis, and biological treatments, like B cell depletion, are known to exhibit higher risk of severe COVID-19 manifestation and increased frequency of breakthrough infections after vaccination. We hypothesized that such increased risk is associated with an aberrant induction of secreted antibodies in the oral cavity. Here we evaluated the levels of secreted antibodies in the oral cavity against the SARS-CoV-2 Spike protein during the course of vaccination in RA patients with or without B cell depletion. We found that total salivary IgG levels were correlated with number of B cells in the blood. Anti-Spike IgG responses 7 days after second vaccination were induced in the oral cavity of all healthy individuals, while only 6 out 23 RA patients exhibited anti-Spike IgG in their saliva regardless of B cell depleting therapy. Importantly, both salivary and serologic anti-Spike IgG and IgA responses towards WT and omicron Spike variants were efficiently induced by third vaccination in RA patients with or without B cell depletion to the levels that were similar to healthy individuals. Altogether, these data advocate for the necessity of three dose vaccination for RA patients to mount anti-Spike antibody responses at the mucosal surfaces and annotate the reduction of secreted salivary IgG by B cell depletion.

[Development of quality standards for patients with axial spondyloarthritis for use in Germany]. / Entwicklung von Qualitätsstandards für Patient*innen mit axialer Spondyloarthritis zum Einsatz in Deutschland.

Quality standards (QS) are measurable constructs designed to quantify gaps in care and subsequently to improve quality of care. The Assessment of SpondyloArthritis International Society (ASAS) recently generated and published international QS for the management of patients with axial spondyloarthritis (axSpA) for the first time. The German Society of Rheumatology (DGRh) then decided to translate, review and possibly adopt these standards by a group of experts from different care settings. Against this background, national QS for the management of patients with axSpA for Germany were developed for the first time. The main focus was on feasibility and practical relevance. Ultimately, nine QS were defined with which the quality of care in Germany can and should be measured and improved.

[Current state, goals and quality standards of outpatient care in rheumatology: position paper of the Professional Association of German Rheumatologists (BDRh)]. / Aktueller Stand, Ziele und Qualitätsstandards der ambulanten Versorgung in der Rheumatologie: Positionspapier des Berufsverbandes der deutschen Rheumatologen (BDRh).

Even in the era of modern guidelines, the treatment of rheumatic diseases is only as good as the framework of rheumatological care within which the treatment is carried out. The access to high-quality medical treatment for all patients is therefore essentially decisive for the prognosis of the patients. This article describes the current state of outpatient treatment in rheumatology and demonstrates which quality projects, such as treatment contracts, outpatient specialized medical treatment (ASV), digitalization and training as specialized rheumatological assistant (RFA), have been created in order to ensure the treatment of our patients. Furthermore, standards are defined that can guarantee a contemporary and guideline-conform treatment in outpatient rheumatological units. As an example it is an affirmation of the Professional Association of German Rheumatologists (BDRh) for ensuring optimal care for all rheumatology patients through early or emergency rheumatology clinics, treat to target, appropriate delegation of medical duties and diversification of treatment, thus an assurance of the quality and comprehensive treatment in rheumatology. The important topic of safeguarding the next generation of rheumatologists, which is indispensable for this, is also discussed.

[Which patients with rheumatoid arthritis do not receive DMARD treatment? Analysis of data from the German Collaborative Arthritis Centers]. / Welche Patienten mit rheumatoider Arthritis erhalten keine DMARD-Therapie? Eine Analyse von Daten der Kerndokumentation.

BACKGROUND: The vast majority of patients with rheumatoid arthritis (RA) included in the national database of the German Collaborative Arthritis Centers are treated with disease-modifying antirheumatic drugs (DMARD). The clinical and patient-related characteristics of patients who did not have DMARD treatment in the longer term were investigated. METHODOLOGY: Between 2012 and 2016 a total of 10,289 patients with RA were documented. Patient characteristics, disease activity and severity, comorbidities and concomitant treatment were descriptively evaluated. Patients who were without DMARDs for more than 1 year and not in remission (disease activity score 28, simple disease activity index or Boolean remission) were analyzed separately. Logistic regression was used to investigate which variables were associated with DMARD treatment. RESULTS: A total of 426 patients were ≤1 year without DMARDs, 1090 > 1 year without DMARDs and 8773 (85%) currently had DMARD treatment. Of the patients who were without DMARDs for more than 1 year, 51% were in remission. Even if no remission criteria were met, the rheumatologists nevertheless found the strived for RA situation in the majority of patients. Of the patients who were without DMARDs for more than 1 year, 13% received glucocorticoid treatment >5 mg/day. In patients with a high degree of severity (odds ratio, OR severe vs. asymptomatic/mild 2.33, 95% confidence interval, CI 1.80;3.02) or positive rheumatoid factor (OR 2.24, CI 1.96;2.56) the chance of receiving DMARD treatment was twice as high. Existing comorbidities did not reduce the chance of receiving DMARD treatment. CONCLUSION: The RA patients in the national database who had no DMARDs for more than 1 year were mostly in remission or with low disease activity. Signs of inadequate disease control were found in only 11% of all patients without DMARD treatment.

[Outpatient specialist medical treatment (ASV)-a new treatment level in rheumatology]. / Ambulante spezialfachärztliche Versorgung (ASV) ­ eine neue Versorgungsebene in der Rheumatologie.

Since April 2018, the new third level care model of outpatient specialist care (ASV) according to §116b of the Social Code Book V (SGBV) has been available for patients with chronic inflammatory rheumatic diseases in Germany. Not only is a multiprofessional cooperation between the disciplines involved in treating rheumatic diseases promoted but also the cooperation between specialized rheumatologists and other specialists in private practice and in hospitals is encouraged. As budget capping limiting services and number of cases do not apply in ASV, a significant improvement of patient care in rheumatology is expected due to an increase in provider capacity. At the end of May 2019, 72 rheumatologists in the first 9 newly approved ASV teams had qualified for this new care concept. Bureaucratic obstacles have so far delayed the implementation of ASV. Difficulties arose in building a team with different specialties, in the process of registration of the teams and the assessment of the registration by certain regional boards responsible for access control. The national associations of rheumatologists, the Professional Association of German Rheumatologists (BDRh), the VRA (Verband der Rheumatologischen Akutkliniken e. V.) and the German Society of Rheumatology (DGRh) campaign for an easier admission of providers to the ASV and for adequate financing of all specialties involved in the ASV. The aim is to realize the chance of the ASV for better rheumatological care nationwide with shorter waiting times for a medical appointment and a better cooperation between specialists.

[Treat-to-target (T2T) recommendation for patients with spondyloarthritis - translation into German]. / "Treat-to-target (T2T)" Empfehlungen für die Behandlung von Patienten mit Spondyloarthritis ­ Übersetzung ins Deutsche.

The management of patients with spondyloarthritis (SpA) has experienced a paradigm shift in recent years. This is true for the treatment of axial as well as peripheral manifestations. International treat to target (T2T) recommendations for SpA based on the T2T strategy have now also been published, which contain 5 higher level principles (A-E) in addition to the 15 recommendations. In order to make the recommendations known and to promote national distribution, German experts have now issued a translation of the T2T recommendations for SpA into German.

[Strategies for improved healthcare of people with the endemic disease rheumatism exemplified by rheumatoid arthritis]. / Strategien zur verbesserten Versorgung von Menschen mit der Volkskrankheit "Rheuma" am Beispiel der rheumatoiden Arthritis.

New therapeutic principles and considerable diagnostic advances have made it possible to define different rheumatic diseases and especially rheumatoid arthritis (RA) at an early stage and by starting an early and aggressive medication a considerable proportion of patients with RA will reach the status of low disease activity or even remission. With the additional development of composite measures to estimate the disease activity of RA, it was the goal of an international working group consisting of rheumatologists and patients to develop recommendations for treating rheumatoid arthritis in a similar way as for patients with hypertension or diabetes, with the aim to achieve remission as often as possible. This treat-to-target initiative has taken off in quite a number of different countries including Germany leading to discussions on how this initiative can be integrated into the specific national healthcare systems and what possibilities would exist for its implementation. To develop strategies for an improved healthcare of people suffering from rheumatic diseases and using RA as an example, action elements and postulates were developed which will be discussed in more detail in the present manuscript.

[Treat-to-target from the perspective of office-based rheumatology]. / "Treat-To-Target" aus der Sicht der niedergelassenen Rheumatologie.

The development of evidence-based treat-to-target (T2T) recommendations alleviates decision-making for the rheumatologist and simultaneously promises substantial improvement of outcome for rheumatoid arthritis (RA) patients. For the office-based rheumatologist in Germany, however, implementation of T2T recommendations contains several difficulties. Limitations arise as a result of an insufficient number of rheumatologists as well as a lack of adequate remuneration both resulting in a lack of time for the individual RA patient. Furthermore budget limitations hinder the appropriate use of antirheumatic drugs and insofar counteract treating to the target of remission. Establishment of selective contracts for rheumatologists by health insurance funds might reduce many of these problems in future for the office-based rheumatologist in Germany.

IgG1 and IgG4 are the predominant subclasses among auto-antibodies against two citrullinated antigens in RA.

OBJECTIVE: Antibody subclasses reflect specific immunological processes and may be indicative of the underlying pathological pattern in an autoimmune disease like RA. We therefore quantified anti-cyclic citrullinated peptides (CCP) and anti- citrullinated vimentin (MCV) IgG subclass titres in RA patients and compared them with the respective titres of antibodies directed against the varicella zoster virus (VZV) and to total serum titres. METHODS: Sera of 77 patients fulfilling the ACR criteria for RA were collected. An IgG subclass-specific ELISA system was then established and combined with commercially available MCV, CCP and VZV pre-coated microtitre plates. RESULTS: Even though IgG1 is the predominant subclass among antibodies against CCP and MCV in RA patients, IgG4 is second with respect to titres and frequencies. This increase in IgG4 among RA-specific antibodies is independent of disease duration and does not reflect a general skewing of the immune response in these patients as overall serum titres and antibodies directed against VZV show a normal distribution of IgG1, IgG2, IgG3 and IgG4. CONCLUSION: Elevated IgG4 titres are specific for auto-antibodies against citrullinated antigens in RA and are indicative of a Th2-biased environment during the generation of auto-reactive plasma cells. We discuss here an indirect role for IgG4 auto-antibodies in hindering the elimination of auto-reactive B and plasma cells and thus driving the autoimmune process.

Four genes are required for the system II cytochrome c biogenesis pathway in Bordetella pertussis, a unique bacterial model.

Unlike other cytochromes, c-type cytochromes have two covalent bonds formed between the two vinyl groups of haem and two cysteines of the protein. This haem ligation requires specific assembly proteins in prokaryotes or eukaryotic mitochondria and chloroplasts. Here, it is shown that Bordetella pertussis is an excellent bacterial model for the widespread system II cytochrome c synthesis pathway. Mutations in four different genes (ccsA, ccsB, ccsX and dipZ) result in B. pertussis strains unable to synthesize any of at least seven c-type cytochromes. Using a cytochrome c4:alkaline phosphatase fusion protein as a bifunctional reporter, it was demonstrated that the B. pertussis wild-type and mutant strains secrete an active alkaline phosphatase fusion protein. However, unlike the wild type, all four mutants are unable to attach haem covalently, resulting in a degraded N-terminal apocytochrome c4 component. Thus, apocytochrome c secretion is normal in each of the four mutants, but all are defective in a periplasmic assembly step (or export of haem). CcsX is related to thioredoxins, which possess a conserved CysXxxXxxCys motif. Using phoA gene fusions as reporters, CcsX was proven to be a periplasmic thioredoxin-like protein. Both the B. pertussis dipZ (i. e. dsbD) and ccsX mutants are corrected for their assembly defects by the thiol-reducing compounds, dithiothreitol and 2-mercaptoethanesulphonic acid. These results indicate that DipZ and CcsX are required for the periplasmic reduction of the cysteines of apocytochromes c before ligation. In contrast, the ccsA and ccsB mutants are not corrected by exogenous reducing agents, suggesting that CcsA and CcsB are required for the haem ligation step itself in the periplasm (or export of haem to the periplasm). Related to this suggestion, the topology of CcsB was determined experimentally, demonstrating that CcsB has four transmembrane domains and a large 435-amino-acid periplasmic region.
