[Influence of smoking, nutrition and other modifiable environmental factors on rheumatoid arthritis]. / Einfluss von Rauchen, Ernährung und anderen modifizierbaren Umweltfaktoren auf die rheumatoide Arthritis.

Numerous reports in recent years have focused on the influence of environmental factors on rheumatoid arthritis. This article provides an overview of the current study situation on the influence of modifiable environmental factors on the development and course of rheumatoid arthritis. Lifestyle factors, such as cigarette smoking, diet, exercise and body weight can be individually influenced. Factors such as air pollution and socioeconomic status can be influenced by environmental and sociopolitical measures at a public level. Epidemiological studies have identified nicotine abuse, an unhealthy diet and obesity as well as a low level of education and social status as risk factors for the development of rheumatoid arthritis. Numerous factors are also associated with a poorer response to treatment and a worse prognosis. As randomized interventional studies on most environmental factors are hardly feasible, the causal relationship of the individual factors to the incidence and progression of rheumatoid arthritis is difficult to quantify. Nevertheless, the current evidence already enables the provision of appropriate counselling to patients with rheumatoid arthritis with respect to a healthy lifestyle including abstaining from cigarette smoking, maintaining a healthy diet, physical activity and avoiding obesity.

[Procedures of complementary medicine in rheumatology]. / Komplementärmedizinische Verfahren in der Rheumatologie.

Patients with diseases of the musculoskeletal system are confronted with a large quantity of treatment offers based on methods of complementary medicine. Despite a considerable number of publications on this topic, the scientific evidence is still poor. This article focuses on Ayurvedic medicine (AM), traditional Chinese medicine (TCM), mind-body medicine and homeopathy. These procedures have a longstanding tradition of practice and each claims to have its own theoretical concept; however, the application in the field of rheumatology can only be recommended either for specific entities or, in the case of homeopathy, not at all. In addition, this article summarizes the evidence for dietary recommendations, nutritional supplements and herbal medicine in rheumatology. The latter topics are frequently discussed in the popular press and are a much-debated issue between physicians and patients; however, clear-cut recommendations for the application on a scientific basis are the exception and mainly consist of the endorsement to adhere to the principles of a Mediterranean diet.

[What is the potential of ChatGPT for qualified patient information? : Attempt of a structured analysis on the basis of a survey regarding complementary and alternative medicine (CAM) in rheumatology]. / Welches Potential hat ChatGPT 3.5 für eine qualifizierte Patienteninformation? : Versuch einer systematischen Analyse anhand einer Befragung zu komplementärmedizinischen Verfahren in der Rheumatologie.

INTRODUCTION: The chatbot ChatGPT represents a milestone in the interaction between humans and large databases that are accessible via the internet. It facilitates the answering of complex questions by enabling a communication in everyday language. Therefore, it is a potential source of information for those who are affected by rheumatic diseases. The aim of our investigation was to find out whether ChatGPT (version 3.5) is capable of giving qualified answers regarding the application of specific methods of complementary and alternative medicine (CAM) in three rheumatic diseases: rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and granulomatosis with polyangiitis (GPA). In addition, it was investigated how the answers of the chatbot were influenced by the wording of the question. METHODS: The questioning of ChatGPT was performed in three parts. Part A consisted of an open question regarding the best way of treatment of the respective disease. In part B, the questions were directed towards possible indications for the application of CAM in general in one of the three disorders. In part C, the chatbot was asked for specific recommendations regarding one of three CAM methods: homeopathy, ayurvedic medicine and herbal medicine. Questions in parts B and C were expressed in two modifications: firstly, it was asked whether the specific CAM was applicable at all in certain rheumatic diseases. The second question asked which procedure of the respective CAM method worked best in the specific disease. The validity of the answers was checked by using the ChatGPT reliability score, a Likert scale ranging from 1 (lowest validity) to 7 (highest validity). RESULTS: The answers to the open questions of part A had the highest validity. In parts B and C, ChatGPT suggested a variety of CAM applications that lacked scientific evidence. The validity of the answers depended on the wording of the questions. If the question suggested the inclination to apply a certain CAM, the answers often lacked the information of missing evidence and were graded with lower score values. CONCLUSION: The answers of ChatGPT (version 3.5) regarding the applicability of CAM in selected rheumatic diseases are not convincingly based on scientific evidence. In addition, the wording of the questions affects the validity of the information. Currently, an uncritical application of ChatGPT as an instrument for patient information cannot be recommended.

[Interdisciplinary centers for autoimmune diseases in Germany]. / Interdisziplinäre Zentren für Autoimmunerkrankungen in Deutschland.

BACKGROUND: Interdisciplinary medical treatment is required to care for patients with complex autoimmune diseases. Although there are an increasing number of interdisciplinary centers for autoimmune diseases in Germany, they are not yet available throughout the country and the focuses and interdisciplinary structures are not organized according to a generally agreed standard. Furthermore, they are not regularly reflected in the general care structure. THE AIM OF THE WORK: To analyze the care structure using as an example an established center and a clinical case to demonstrate the usefulness of in-house standardized procedures. MATERIAL AND METHODS: In order to determine the status quo regarding interdisciplinary centers for autoimmune diseases in Germany, a university hospital is exemplarily presented for a structural analysis and a case presentation from another center to demonstrate the importance of an interdisciplinary patient care. RESULTS: At the selected center for autoimmune diseases of the university hospital, patients with autoimmune diseases receive interdisciplinary care from experts from various disciplines. The structures are anchored in an organizational chart. The case report demonstrates a standardized diagnostic and therapeutic pathway (standardized operating procedures, SOP) in a patient with systemic sclerosis and lung involvement. DISCUSSION: The article discusses which measures are necessary across disciplines for comprehensive diagnostics and treatment of certain autoimmune diseases, which challenges arise during implementation and which advantages can arise compared to guidelines because, among other things, they can be immediately adapted. The establishment of a national consensus for the structure, necessary settings and implementation into patient care within an interdisciplinary center for autoimmune diseases is desirable.

Survey on the working, training, and research conditions of resident physicians in internistic and rheumatological continuing education-BEWUSST.

BACKGROUND: Data on the training and continuing education situation of residents in the field of internal medicine and rheumatology are not available for Germany. For this reason, the Commission for Education and Training of the German Society of Rheumatology (DGRh) initiated the BEWUSST survey on the working, training and research conditions of residents in rheumatology. METHODS: A total of 102 questions on the topics of working conditions in everyday professional life, continuing medical education and training, compatibility of career and family, compatibility of work and research, perspectives as a rheumatologist and practical activities were included in an online questionnaire. RESULTS: A total of 102 participants took part in the survey. Of the respondents 48.1% were satisfied with their professional situation, 40.2% of the participants were supervised by a specialist mentor and 54.9% were working as scientists during their work as a physician. A compatibility of family and career was possible for 34.7%. After completion of the residency 52.9% of the respondents aspired to a combined clinical and outpatient activity. CONCLUSION: Half of the trainee rheumatologists are satisfied with their professional activities, although mentoring of the assistants in training should be further improved. With respect to the desired combined clinical and outpatient activity, the existing options should be expanded or new professional fields of activity should be established, so that the specialty remains attractive for the upcoming generations.

Anti-acid therapy in SSc-associated interstitial lung disease: long-term outcomes from the German Network for Systemic Sclerosis.

OBJECTIVES: Gastroesophageal reflux disease (GERD) occurs frequently in patients with SSc. We investigated whether the presence of GERD and/or the use of anti-acid therapy, specifically proton-pump inhibitors (PPIs), are associated with long-term outcomes, especially in SSc-associated interstitial lung disease (SSc-ILD). METHODS: We retrospectively analysed patients with SSc and SSc-ILD from the German Network for Systemic Sclerosis (DNSS) database (2003 onwards). Kaplan-Meier analysis compared overall survival (OS) and progression-free survival (PFS) in patients with GERD vs without GERD (SSc and SSc-ILD), and PPI vs no PPI use (SSc-ILD only). Progression was defined as a decrease in either percentage predicted forced vital capacity of ≥10% or single-breath diffusing capacity for carbon monoxide of ≥15%, or death. RESULTS: It was found that 2693/4306 (63%) registered patients with SSc and 1204/1931 (62%) with SSc-ILD had GERD. GERD was not associated with decreased OS or decreased PFS in patients in either cohort. In SSc-ILD, PPI use was associated with improved OS vs no PPI use after 1 year [98.4% (95% CI: 97.6, 99.3); n = 760 vs 90.8% (87.9-93.8); n = 290] and after 5 years [91.4% (89.2-93.8); n = 357 vs 70.9% (65.2-77.1); n = 106; P < 0.0001]. PPI use was also associated with improved PFS vs no PPI use after 1 year [95.9% (94.6-97.3); n = 745 vs 86.4% (82.9-90.1); n = 278] and after 5 years [66.8% (63.0-70.8); n = 286 vs 45.9% (39.6-53.2); n = 69; P < 0.0001]. CONCLUSION: GERD had no effect on survival in SSc or SSc-ILD. PPIs improved survival in patients with SSc-ILD. Controlled, prospective trials are needed to confirm this finding.

[Recommendations of the committee on complementary medicine and nutrition in ayurvedic medicine, homeopathy, nutrition and Mediterranean diet]. / Empfehlungen der Kommission Komplementäre Heilverfahren und Ernährung zu ayurvedischer Medizin, Homöopathie, Ernährung und mediterraner Kost.

Methods of complementary and alternative medicine (CAM) are appealing for many patients with rheumatic diseases. The scientific data are currently characterized by a large number of publications that stand in contrast to a remarkable shortage of valid clinical studies. The applications of CAM procedures are situated in an area of conflict between efforts for an evidence-based medicine and high-quality therapeutic concepts on the one hand and ill-founded or even dubious offers on the other hand. In 2021 the German Society of Rheumatology (DGRh) launched a committee for CAM and nutrition, which aims to collect and to evaluate the current evidence for CAM applications and nutritional medical interventions in rheumatology, in order to elaborate recommendations for the clinical practice. The current article presents recommendations for nutritional interventions in the rheumatological routine for four areas: nutrition, Mediterranean diet, ayurvedic medicine and homeopathy.

[Survey on the working, training, and research conditions of resident physicians in internistic and rheumatological continuing education-BEWUSST]. / Befragung zu den Arbeits-, Weiterbildungs- und Forschungsbedingungen von Assistenzärztinnen und -ärzten in der internistisch-rheumatologischen Weiterbildung ­ BEWUSST.

BACKGROUND: Data on the training and continuing education situation of residents in the field of internal medicine and rheumatology are not available for Germany. For this reason, the Commission for Education and Training of the German Society of Rheumatology (DGRh) initiated the BEWUSST survey on the working, training and research conditions of residents in rheumatology.

[Rheumatology training positions in Germany]. / Rheumatologische Weiterbildungsstellen in Deutschland.

BACKGROUND: In the next few years many general practitioners and specialists will retire. As in other disciplines the question arises in rheumatology whether sufficient training positions are available to maintain or expand the supply of care according to demand. Therefore, the German Society of Rheumatology (DGRh) has assigned its committee for education and training to review the currently available training opportunities in Germany. The aim of this work is the quantitative survey of the training capacity to become a specialist in internal medicine and rheumatology. METHODS: Within the framework of this study, a survey was conducted via the homepages of the 17 state medical associations to determine the postgraduate medical officers, their place of work and the duration of their postgraduate training capabilities. Based on the data, a nationwide survey of training positions was conducted. RESULTS: Specialized rheumatology training is established at 229 training centers in Germany, whereby data from 187 training sites were available for analysis. The training locations are distributed as followed: 52.4% clinical sector and 47.6% outpatient sector. In total, 478.4 training positions are available in Germany (clinical sector: 391.4 and outpatient sector: 87) and 17.2% of the positions (clinical sector: 11.4% and outpatient sector: 43.1%) are not occupied. CONCLUSION: Based on this study, it can be shown that most of the continuing education positions are available in the clinical sector. In contrast, half of the training positions in the outpatient area are not filled. In order to improve the training situation, it is essential to integrate outpatient colleagues into the training program. This presupposes that further training is supported or financed by the healthcare system. In this context, optimal rheumatological care must be permanently guaranteed throughout Germany in order to provide sufficient care for the approximately 2 million patients with inflammatory rheumatic diseases.

[Safety aspects of the treatment with glucocorticoids for rheumatoid arthritis]. / Sicherheitsaspekte der Therapie mit Glukokortikoiden bei rheumatoider Arthritis.

Glucocorticoids (GC) are still the recommended initial treatment for rheumatoid arthritis, although the treatment should be temporary and confined to the administration of low doses. The complex mechanism of action is accompanied by side effects that particularly occur in long-term treatment exceeding 5 mg prednisolone per day. In this dosage range they promote osteoporosis, diabetes and hyperglycemia as well as cardiovascular events and infections, thereby contributing to an excess mortality. The risks of GC treatment are dependent on patient-related parameters, such as age, comorbidity and additional medication. A negative influence of very low steroid doses on overall survival is possibly due to high cumulative steroid doses; however, the data in this respect are contradictory. Recently, a validated index was developed to monitor GC-related toxicity. In the future, this index should help to describe the advantages of steroid-sparing treatment strategies. In the future, more selectively acting substances could achieve an uncoupling of desired and adverse effects.

Vasculitis and the ear: a literature review.

PURPOSE OF REVIEW: Systemic vasculitides as a group of inflammatory disorders of blood vessels may show clinical manifestations in the ear. This article reviews the recent literature about vasculitis of the ear or the cochleovestibular system, focusing on giant-cell arteritis, Takayasu's arteritis, polyarteritis nodosa, Kawasaki disease, microscopic polyangiitis, granulomatosis with polyangiitis (GPA), eosinophilic GPA, systemic lupus erythematosus, Cogan's syndrome and Behçet's disease. RECENT FINDINGS: In patients with vasculitis, hearing impairment is a frequent problem, followed by tinnitus and vertigo. The severity of sensorineural hearing loss can range from mild impairment to deafness. Autoimmune diseases can induce a conductive hearing loss as a result of effusions of the middle ear, the inflammation of the mucosa of the Eustachian tube, or the involvement of the ossicular chain. Vertigo may be caused by the temporary or permanent occlusion of the labyrinthine or the anterior vestibular artery. Middle ear inflammation is frequent in GPA and eosinophilic GPA. SUMMARY: The progressive sensorineural hearing loss in polyarteritis nodosa or Cogan's syndrome patients may be treated by cochlear implantation.

Is periodontitis a prognostic factor in order to indicate antibodies against citrullinated peptides in patients with rheumatoid arthritis?

OBJECTIVES: In this cross-sectional study we investigated antibody titres against cyclic citrullinated peptides derived from filaggrin (anti-CCP) and citrullinated α-enolase (anti-CEP-1) among patients with RA as a function of periodontal findings. METHODS: 107 patients with RA (median age 56 years, 75% females) were included. For periodontal diagnoses missing teeth, periodontal epithelial surface area, periodontal inflamed surface area and periodontal diagnosis according to the working group's guidelines of the Center for Disease Control and Prevention were determined. Subgingival bacterial DNA of five periodontopathic bacteria was assessed by PCR with sequence-specific oligonucleotides. Anti-CCP and anti-CEP-1 antibodies in plasma samples were investigated using enzyme-linked immunosorbent assays. Low resolution human leukocyte antigen (HLA) typing was carried out using PCR with sequence-specific primers. RESULTS: PESA was found associated with a low adjusted odds ratio for anti-CCP positivity (OR=1.002, p=0.040). All patients who were infected with Aggregatibacter actinomycetemcomitans were simultaneously anti-CCP positive (p=0.043). HLA-DRB1*13 lowered the adjusted odds ratio for anti-CCP (OR=0.073, p=0.002) and anti-CEP-1 (OR=0.068, p=0.018) positivity whereas HLA-DRB1*07 indicated a lower risk only for demonstrable anti-CCP antibodies (OR=0.079, p=0.004). HLA-DRB1*04 was associated with increased adjusted odds ratio for anti-CEP-1 positivity (OR=4.154, p=0.005) and the simultaneous proof of both investigated autoantibodies (OR=3.725, p=0.011). CONCLUSIONS: Among patients with RA periodontitis may be a minor risk factor for anti-CCP positivity. Our data first provide evidence that an infection with A. actinomycetemcomitans is associated with an increased formation of anti-CCP. HLA phenotype proved to be a significant risk indicator for both investigated antibodies.

[Mesenchymal stem cell treatment in autoimmune diseases]. / Mesenchymale Stammzelltherapie bei Autoimmunerkrankungen.

Mesenchymal stromal or stem cells (MSC) possess strong immunomodulatory properties. Due to their impressive potential to differentiate into various cell types they are capable of inducing mechanisms of tissue repair. Experimental data have demonstrated impaired MSC function in several rheumatic diseases in vitro; however, the relevance of these phenomena for the pathogenesis of rheumatic disorders has not been convincingly demonstrated. Nevertheless, allogeneic MSC transplantation (MSCT), and possibly autologous MSCT as well, could prove to be an interesting instrument for the treatment of autoimmune rheumatic diseases. The first clinical trials have demonstrated positive effects in systemic lupus erythematosus, systemic sclerosis and Sjogren's syndrome; however, questions regarding the long-term benefits and safety as well as the best source, the optimal cultivation technique and the most effective way of application of MSC are still unanswered.

[Epidemiology and outcome of patients with rheumatic diseases in the intensive care unit]. / Epidemiologie und Outcome von Rheumapatienten auf der Intensivstation.

Patients with rheumatic diseases have an increased risk for admission to an intensive care unit (ICU) compared with individuals without these diseases. Besides cardiovascular events, infection complications are frequently the reason for ICU treatment. For autoimmune systemic diseases, such as systemic lupus erythematosus (SLE) and granulomatosis with polyangiitis (GPA), it is not uncommon for the disease to be first diagnosed during intensive medical care. In addition, flares of these diseases can necessitate ICU admission of the patients. The mortality of patients with rheumatic diseases on the ICU is increased compared with control collectives, especially in patients suffering from life-threatening infections. Treatment with corticosteroids is associated with an increased risk for ICU admission as well as a poorer survival rate. In contrast, patients treated with conventional and biologic disease-modifying anti-rheumatic drugs (DMARD) are less likely to need ICU treatment, compared with rheumatism patients without these medications. Among the established scoring systems applied to estimate the prognosis of ICU patients, the APACHE II score is the best investigated system in patients suffering from rheumatic diseases. This score probably reflects the condition of these patients better than other scoring systems.

[Survey of rheumatologists in Saxony, Saxony-Anhalt and Thuringia regarding the occupational situation and activities in further education: no way out of the undersupply of rheumatological care]. / Befragung von Rheumatologen in Sachsen, Sachsen-Anhalt und Thüringen zu Weiterbildungstätigkeit und beruflicher Situation: Kein Ausweg aus der rheumatologischen Unterversorgung.

INTRODUCTION: Many regions in the middle of Germany have a deficit in specialized rheumatological care. A survey was undertaken to investigate whether the regional capacities for rheumatological advanced training are sufficient to provide an adequate number of rheumatologists in the future. METHODS: All 91 rheumatologists registered in Saxony, Saxony-Anhalt and Thuringia received a questionnaire that was sent back by 66% of the recipients (23 responses from Saxony, 19 from Saxony-Anhalt, 18 from Thuringia). Of the rheumatologists 41 were in private practice, 19 worked in an inpatient department and the mean duration of professional activity was 18 years. RESULTS: Over the last decade the number of patients treated by rheumatologists in private practices increased from 1200 to 1500 per quarter year (p < 0.001), whereas the number of first consultations rose from 100 to 130 per quarter year (p = 0.06). The waiting time for a first consultation rose from 8 to 11 weeks (p = 0.01), 32% of the responders indicated that the conditions for outpatient treatment had either improved or had remained constant during the last 10 years, whereas 60% reported a mild or marked deterioration and 48% stated that the number of rheumatologists had decreased within the same time frame. Only 20% indicated that they had a definite successor in the practice after retirement. All inpatient departments also had an outpatient office. During the last 10 years, the number of consultations per quarter year decreased from 1100 to 700 (not significant), while the waiting time doubled from 6 to 12 weeks (rounded mean). Of the rheumatologists in private practice eight are currently entitled to provide advanced education in rheumatology, with a median training period of 18 months; however, none of the responding physicians had actually brought assistant doctors to the final examination during the last decade and only one prospective rheumatologist was currently completing training in a private practice setting. Only 6 out of 12 inpatient rheumatological facilities are entitled to educate rheumatologists over the whole training period, 5 facilities were not involved in training at all and 7 indicated that they lacked applications for rheumatology training. During the last 10 years, 37 rheumatologists completed the training of which 18 went into private practice, 8 worked as general practitioners and 29 remained in the region of their initial training. CONCLUSION: Given the increase in the number of outpatients served, the volume of training activities in rheumatology is hardly sufficient to improve the deficit of rheumatological care in the middle of Germany.

An online, two-day educational seminar had no impact on disease-specific knowledge in patients with systemic sclerosis.

Systemic sclerosis (SSc) is a multifaceted disease, and its diagnosis triggers substantial anxiety and uncertainty for those affected. Currently, there are no valid data describing the impact of disease-specific patient education on the disease knowledge available. We created a two-day, online educational seminar to provide SSc patients with disease-specific information. The primary objective of the study was to observe the change in the disease-specific knowledge of the patients. A total of 118 patients were randomized into an intervention group and a waiting list control group. The change in knowledge was assessed using a multiple-choice test. The intervention group completed the questionnaire before, directly after, and 3 months after the seminar, while the waiting list control group also took the test 3 months before the seminar to rule out nonspecific learning. The primary outcome measure was the score difference between baseline and 3 months after baseline. The study was registered in the German Clinical Trials Register (protocol code DRKS00024915). The educational seminar resulted in a small, but measurable, increase in knowledge. While the two tests in the waiting list control group prior to the seminar did not show a nonspecific increase in disease knowledge, the intervention led to a numerical increase in knowledge (mean ± sd score difference 0.34 ± 1.31, 95% CI (- 0.23; 0.86), p = 0.26) that did not reach statistical significance. Multiple linear regression analysis showed that being a member of a self-help group (ß = 1.12; p = 0.03) is a positive predictor of a higher disease knowledge. Although highly appreciated by participants, a two-day online seminar may not be the most appropriate format to generate measurable disease-specific knowledge. Self-help group membership was a positive predictor of a higher level of disease-specific knowledge prior to the educational seminar and should be recommended to every affected person.
