RESUMEN

Objective: Pregnancy may influence the course of inflammatory rheumatic diseases and, conversely, rheumatic and musculoskeletal diseases (RMDs) can affect the outcome of pregnancy. This study aimed to retrospectively analyse the outcome of pregnancy and disease in women with RMDs.Method: Subjects were patients with high-risk pregnancy and connective tissue diseases (CTDs) or inflammatory joint diseases (IJDs) managed at a specialized rheumatology outpatient clinic from 2007 to 2014. Data from conception to 6 months postpartum were collected from medical records and a questionnaire, and analysed regarding clinical symptoms, medications, pregnancy complications, birth outcomes, and infant development. Generalized estimating equations were used to compare the groups (CTD vs IJD).Results: The eligible 66 pregnancies in 57 RMD patients were divided into two groups by RMD type: CTD (n = 48) or IJD (n = 18). The live birth rate was 97% overall. Pregnancy complications (excluding two twin pregnancies) were incurred in 39.1%: miscarriage (n = 2), premature delivery (n = 12), small-for-gestational-age infants (n = 5), and/or pregnancy-related diseases (n = 14). Three children born to women with CTDs had affected development (autism spectrum disorder, congenital heart disease, bronchopulmonary dysplasia). CTD infants had a significantly lower mean gestational age (in weeks) (p = 0.042), weight (p = 0.009), and length (p = 0.016) at birth than IJD infants.Conclusion: Although the live birth rate was high, complications occurred in 39.1% of pregnancies in this cohort. Therefore, interdisciplinary management of pregnant women with RMDs at specialized clinics is strongly recommended.

RESUMEN

In the current SARS-CoV-2 pandemic there are many questions regarding the safe treatment of patients with inflammatory rheumatic diseases. Many of these questions cannot yet be answered on an evidence-based basis and this does not make patient care easy. The German Society for Rheumatology (DGRh) hopes that these initial recommendations will provide support for specific issues in the care of patients with inflammatory rheumatic diseases in view of the current threat posed by SARS-CoV-2. In order to take advantage of the dynamic worldwide gain in knowledge for our patients, the recommendations will be updated regularly. The updated versions of the recommendations are deposited on the homepage of the DGRh.

RESUMEN

The prognosis of rheumatoid arthritis (RA) has been significantly improved in recent decades. This is mainly due to earlier detection, better diagnostics and new treatment options, such as the optimized use of classical disease-modifying antirheumatic drugs (DMARD) and biologicals. Other factors involved were earlier intervention, improved availability of information and analyses and certainly also standardization of care (e.g. guidelines). An additional important component is close monitoring of disease activity in order to be able to adapt the treatment in a timely manner and thus prevent damage. The demand for tight control is the subject of this article.

RESUMEN

BACKGROUND: Many studies and registry data confirm that depression, often associated with anxiety disorders is very often found in patients with rheumatoid arthritis (RA). To what extent these psychiatric disorders are already relevant at a very early stage of the disease, has currently not been adequately investigated. METHODS: In this study 176 patients with early joint symptoms (<1 year) were surveyed in an early arthritis consultation (EAC). The hospital anxiety and depression scale (HADS) was completed by the patients to examine the prevalence of depressive and anxiety symptoms. The results were compared to normative data of the general German population and between the diagnosis groups. RESULTS: With 47.7% the prevalence of global distress for EA patients was almost twice as high compared to the corresponding group from the general population. This was also confirmed for depressive and anxiety symptoms. The EA patients without confirmed evidence of musculoskeletal inflammatory rheumatic disease (RD) showed nearly the same point prevalence as patients with confirmed RD. In multiple logistic regression the health assessment questionnaire (HAQ) was positively associated with global distress (odds ratio, OR 3.63) while the visual analogue scale (VAS) for global disease activity was positively associated with symptoms of depression (OR 1.03). Female EA patients (OR 5.45) appear to have a higher probability for experiencing corresponding symptoms, whereas patients over 60 years old appear to have less anxiety than younger patients (OR 0.11). CONCLUSION: The high prevalence of symptoms of depression and anxiety in EA patients compared to the general population is a challenge for rheumatologists, orthopedists and general practitioners, particularly with respect to the differentiation of possible psychosomatic components in noninflammatory joint complaints. The results suggest that screening for psychiatric problems in patients with rheumatism should be evaluated as soon as possible as these can have a great impact on the perception of pain and physical functional status from the very beginning.

RESUMEN

When it comes to legal aspects and doctors have to go to court, most likely they will serve as an expert or regular witness or as a defendant in a civil litigation in case of recourse claims and only rarely as defendants in a criminal case. With the exception of expert testimonies by seasoned physicians, this is not usually an easy situation. This article addresses important aspects of the preparation for a trial and its procedures. If appropriately prepared, and if necessary represented by a good attorney, these sometimes emotionally stressful situations can be mastered quite well.

RESUMEN

Rheumatic diseases are among the most common chronic inflammatory disorders. Besides severe pain and progressive destruction of the joints, rheumatoid arthritis (RA), spondyloarthritides (SpA) and psoriatic arthritis (PsA) impair working ability, reduce quality of life and if treated insufficiently may enhance mortality. With the introduction of biologics to treat these diseases, the demand for biomarkers of early diagnosis and therapeutic stratification has been growing continuously. The main goal of the consortium ArthroMark is to identify new biomarkers and to apply modern imaging technologies for diagnosis, follow-up assessment and stratification of patients with RA, SpA and PsA. With the development of new biomarkers for these diseases, the ArthroMark project contributes to research in chronic diseases of the musculoskeletal system. The cooperation between different national centers will utilize site-specific resources, such as biobanks and clinical studies for sharing and gainful networking of individual core areas in biomarker analysis. Joint data management and harmonization of data assessment as well as best practice characterization of patients with new imaging technologies will optimize quality of marker validation.

RESUMEN

BACKGROUND: The German Registry of Autoimmune Diseases 2 (GRAID2) is a retrospective, non-interventional, multicenter registry study collecting data from patients with inflammatory, mainly rheumatic diseases refractory to standard of care therapy and treated with an off-label biologic therapy. The retrospective documentation comprised case history, diagnosis, course of disease (including safety and global efficacy). The objective was to evaluate the global clinical outcome and safety of off-label biologic therapy in clinical practice. RESULTS: Data from 311 patients with an overall observation period of 338.5 patient-years were collected. The mean patients age was 47.8 years with 56.9% females. The most frequently documented diagnoses comprised rejection prophylaxis/therapy after renal transplantation (NTX, 18.3%), ANCA-vasculitides (17.4%), systemic lupus erythematosus (SLE, 10.3%), autoinflammatory fever syndromes (8.4%), autoimmune myositis (7.4%) and pemphigus (5.8%). Documented biologic therapies included rituximab (RTX, 70.1%), tocilizumab (TCZ, 9.3%), infliximab (IFX, 7.1%), anakinra (ANK, 5.5%), adalimumab (ADA, 3.5%), etanercept (ETA, 2.3%) and certolizumab (CTZ, 0.6%). After initiation of off-label biologic treatment, tolerability was assessed by the physicians as "very good"/"good" in 95.5%. Altogether, 275 adverse events were documented and of these, 104 were classified as serious adverse events and occurred in 62 patients. In 19 of these patients severe infections (30.6%) were documented, resulting in a rate of 5.6 severe infections per 100 patient years. A total of six deaths were documented, while five of these cases were rated as not related to the biologics treatment. Notably, the use of RTX in patients with small vessel vasculitides and of TCZ in patients with large vessel vasculitides prior to their approval support their relevance in clinical management of patients with severe diseases. CONCLUSION: The results of this registry together with data of GRAID1 provide evidence that use of off-label biologic therapies in patients with inflammatory rheumatic diseases refractory to conventional treatment did not result in any new safety signal already known for these compounds or subsequently shown by clinical trials in certain entities.

RESUMEN

BACKGROUND: Medication-based strategies to treat rheumatoid arthritis are crucial in terms of outcome. They aim at preventing joint destruction, loss of function and disability by early and consistent inhibition of inflammatory processes. OBJECTIVE: Achieving consensus about evidence-based recommendations for the treatment of rheumatoid arthritis with disease-modifying anti-rheumatic drugs in Germany. METHODS: Following a systematic literature research, a structured process among expert rheumatologists was used to reach consensus. RESULTS: The results of the consensus process can be summed up in 6 overarching principles and 10 recommendations. There are several new issues compared to the version of 2012, such as differentiated adjustments to the therapeutic regime according to time point and extent of treatment response, the therapeutic goal of achieving remission as assessed by means of the simplified disease activity index (SDAI) as well as the potential use of targeted synthetic DMARDs (JAK inhibitors) and suggestions for a deescalating in case of achieving a sustained remission. Methotrexate still plays the central role at the beginning of the treatment and as a combination partner in the further treatment course. When treatment response to methotrexate is inadequate, either switching to or combining with another conventional synthetic DMARD is an option in the absence of unfavourable prognostic factors. Otherwise biologic or targeted synthetic DMARDs are recommended according to the algorithm. Rules for deescalating treatment with glucocorticoids and-where applicable-DMARDs give support for the management of patients who have reached a sustained remission. DISCUSSION: The new guidelines set up recommendations for RA treatment in accordance with the treat-to-target principle. Modern disease-modifying drugs, now including also JAK inhibitors, are available in an algorithm.

RESUMEN

OBJECTIVES: To assess the efficacy and safety of certolizumab pegol (CZP)+dose-optimised methotrexate (MTX) versus placebo (PBO)+dose-optimised MTX in inducing and sustaining clinical remission in DMARD-naïve patients with moderate-to-severe, active, progressive rheumatoid arthritis (RA), with poor prognostic factors over 52 weeks. METHODS: DMARD-naïve patients with ≤1 year of active RA were randomised (3:1) in a double-blind manner to CZP (400 mg Weeks 0, 2, 4, then 200 mg Q2W to Week 52)+MTX or PBO+MTX (the mean optimised-MTX dose=21 and 22 mg/week, respectively). Sustained remission (sREM) and sustained low disease activity (sLDA; DAS28(ESR)<2.6 and DAS28(ESR)≤3.2, respectively, at both Weeks 40 and 52) were the primary and secondary endpoints. RESULTS: Patients were randomised to CZP+MTX (n=660) and PBO+MTX (n=219). At Week 52, significantly more patients assigned to CZP+MTX compared with PBO+MTX achieved sREM (28.9% vs 15.0%, p<0.001) and sLDA (43.8% vs 28.6%, p<0.001). Inhibition of radiographic progression and improvements in physical functioning were significantly greater for CZP+MTX versus PBO+MTX (van der Heijde modified total Sharp score (mTSS) mean absolute change from baseline (CFB): 0.2 vs 1.8, p<0.001, rate of mTSS non-progressors: 70.3% vs 49.7%, p<0.001; least squares (LS) mean CFB in Health Assessment Questionnaire-Disability Index (HAQ-DI): -1.00 vs -0.82, p<0.001). Incidence of adverse events (AEs) and serious AEs was similar between treatment groups. Infection was the most frequent AE, with higher incidence for CZP+MTX (71.8/100 patient-years (PY)) versus PBO+MTX (52.7/100 PY); the rate of serious infection was similar between CZP+MTX (3.3/100 PY) and PBO+MTX (3.7/100 PY). CONCLUSIONS: CZP+dose-optimised MTX treatment of DMARD-naïve early RA resulted in significantly more patients achieving sREM and sLDA, improved physical function and inhibited structural damage compared with PBO+dose-optimised MTX. TRIAL REGISTRATION NUMBER: NCT01519791.

RESUMEN

BACKGROUND: In rheumatoid arthritis (RA), hand synovitis appears especially in wrist, metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints. In hand osteoarthritis (OA), potential inflammatory changes are mainly present in PIP and distal interphalangeal (DIP) joints. Joint inflammation can be visualised by fluorescence optical imaging (FOI) and musculoskeletal ultrasound (US). OBJECTIVE: Comparison of the amount and distribution of inflammatory signs in wrist and finger joints of the clinically dominant hand in patients with OA and RA by FOI and gray-scale (GSUS) and power Doppler US (PDUS). METHODS: FOI and GSUS/PDUS were performed in 1.170 joints (wrists, MCP, PIP, DIP) in 90 patients (67 RA, 23 OA). Joint inflammation was graded by a semiquantitative score (0-3) for each imaging method. RESULTS: GSUS/PDUS showed wrist and MCP joints mostly affected in RA. DIP joints were graded higher in OA. In FOI, RA and OA featured inflammatory changes in the respective joint groups depending on the phase of fluorescence dye flooding. CONCLUSIONS: US and FOI detected inflammation in both RA and OA highlighting the inflammatory component in the course of OA. The different inflammatory patterns and various shapes of fluorescence enhancement in FOI may offer opportunities to distinguish and determine the inflammatory status in both diseases.

RESUMEN

BACKGROUND: Since the publication of the European League Against Rheumatism recommendations for the pharmacological treatment of psoriatic arthritis (PsA) in 2012, new evidence and new therapeutic agents have emerged. The objective was to update these recommendations. METHODS: A systematic literature review was performed regarding pharmacological treatment in PsA. Subsequently, recommendations were formulated based on the evidence and the expert opinion of the 34 Task Force members. Levels of evidence and strengths of recommendations were allocated. RESULTS: The updated recommendations comprise 5 overarching principles and 10 recommendations, covering pharmacological therapies for PsA from non-steroidal anti-inflammatory drugs (NSAIDs), to conventional synthetic (csDMARD) and biological (bDMARD) disease-modifying antirheumatic drugs, whatever their mode of action, taking articular and extra-articular manifestations of PsA into account, but focusing on musculoskeletal involvement. The overarching principles address the need for shared decision-making and treatment objectives. The recommendations address csDMARDs as an initial therapy after failure of NSAIDs and local therapy for active disease, followed, if necessary, by a bDMARD or a targeted synthetic DMARD (tsDMARD). The first bDMARD would usually be a tumour necrosis factor (TNF) inhibitor. bDMARDs targeting interleukin (IL)12/23 (ustekinumab) or IL-17 pathways (secukinumab) may be used in patients for whom TNF inhibitors are inappropriate and a tsDMARD such as a phosphodiesterase 4-inhibitor (apremilast) if bDMARDs are inappropriate. If the first bDMARD strategy fails, any other bDMARD or tsDMARD may be used. CONCLUSIONS: These recommendations provide stakeholders with an updated consensus on the pharmacological treatment of PsA and strategies to reach optimal outcomes in PsA, based on a combination of evidence and expert opinion.

RESUMEN

Issues of fertility and pregnancy require special attention in the long-term care of patients with autoimmune diseases (AD), who are candidates for haematopoietic stem cell transplantation (HSCT). In this single-centre observational study, we report fertility status and pregnancy outcomes in 15 patients (11 female and 4 male) after immunoablation with cyclophosphamide, antithymocyte globulin and autologous CD34+-selected HSCT for severe, refractory AD. The median follow-up after HSCT was 12 years (range 2-16 years). Impaired fertility was observed in six patients (five females and one male) before HSCT based on sexual hormone measurements. Higher age and cumulative cyclophosphamide dosage before HSCT correlated with fertility impairment. Median serum level of follicle-stimulating hormone (FSH) was significantly higher in female patients at 1 year after HSCT compared to baseline values, but premature ovarian failure developed in only one patient. Four women had five pregnancies and six healthy offsprings during follow-up, and no miscarriages were observed. The mothers were in treatment-free remissions during conception. No peripartal flare of their AD occurred. Although AD patients undergoing HSCT are at risk of developing infertility, pre-HSCT treatment and patients' age seem to have higher impact on long-term fertility status than HSCT itself. HSCT offers the opportunity to conceive during treatment-free remissions with favourable pregnancy outcomes.

RESUMEN

In a joint initiative by the boards of the German Society for Rheumatology (DGRh) and the Association of Rheumatology Clinics (VRA) the European "standards of care" for rheumatoid arthritis, recently suggested by the European Musculoskeletal Conditions Surveillance and Information Network (eumusc.net) and supported by the European League Against Rheumatism (EULAR), were translated and annotated. The recommendations include aspects of the management of the disease, actual medical care, and access to information - this includes all types of support people with RA need, and, last but not least communication of the necessary knowledge. Furthermore, health care structures such as the availability of medical staff with relevant expertise are also important.

RESUMEN

This article presents a particularly severe case of adult onset Still's disease aggravated by small vessel vasculitis. A satisfactory therapy was concluded 1.5 years after onset of the disease. The small vessel vasculitis was difficult to treat: methotrexate (MTX), cyclophosphamide and rituximab were not sufficiently effective. Tocilizumab in combination with intravenous immunoglobulin (IVIG) induced remission and maintenance therapy was carried out with tocilizumab.

RESUMEN

OBJECTIVE: CD22 is a surface molecule exclusively expressed on B cells that regulates adhesion and B cell receptor (BCR) signaling as an inhibitory coreceptor of the BCR. Central downstream signaling molecules that are activated upon BCR engagement include spleen tyrosine kinase (Syk) and, subsequently, phospholipase Cγ2 (PLCγ2), which results in calcium (Ca(2+)) mobilization. The humanized anti-CD22 monoclonal antibody epratuzumab is currently being tested in clinical trials. This study was undertaken to determine the potential mechanism by which this drug regulates B cell activation. METHODS: Purified B cells were preincubated with epratuzumab, and the colocalization of CD22 and CD79α, without BCR engagement, was assessed by confocal microscopy. The phosphorylation of Syk (Y348, Y352) and PLCγ2 (Y759) as well as the Ca(2+) flux in the cells were analyzed by flow cytometry upon stimulation of the BCR and/or Toll-like receptor 9 (TLR-9). The influence of CD22 ligation on BCR signaling was assessed by pretreating the cells with epratuzumab or F(ab')(2) fragment of epratuzumab, in comparison with control cells (medium alone or isotype-matched IgG1). RESULTS: Epratuzumab induced colocalization of CD22 and components of the BCR independent of BCR engagement, and also reduced intracellular Ca(2+) mobilization and diminished the phosphorylation of Syk and PLCγ2 after BCR stimulation in vitro. Inhibition of kinase phosphorylation was demonstrated in both CD27- and CD27+ B cells, and this appeared to be independent of Fc receptor signaling. Preactivation of the cells via the stimulation of TLR-9 did not circumvent the inhibitory effect of epratuzumab on BCR signaling. CONCLUSION: These findings are consistent with the concept of targeting CD22 to raise the threshold of BCR activation, which could offer therapeutic benefit in patients with autoimmune diseases.

RESUMEN

The working profile of university hospitals includes medical education, research and implementation of medical innovations as well as large volume patient care. University hospitals offer inpatient, day care and outpatient care which are of essential value for many patients. Besides their primary role in treating rare and orphan diseases and complex cases, they increasingly support general patient care. There are different kinds of outpatient access and treatment options available. The funding of university hospitals and clinics is based on general university funding, income from third party funds for research, income from patient care and funding from the federal states for investments. In recent years these institutions have suffered more and more from economic deficits, a lack of investment and inadequate funding whereby high performance medicine cannot be sufficiently supported. Professors are developing into scientific managers and are frequently assessed by economic outcome and competitiveness. At the same time they are embedded in the structures of the university and are not in the position to make decisions on their own, in contrast to doctors in private practices. Therefore, processes, necessary investments and restructuring are significantly delayed. There is a need to develop strategies for long-term funding and providing university hospitals and clinics with the means to deliver the necessary services.

RESUMEN

BACKGROUND: In contrast to the restrictive nature of randomised controlled trials (RCT), non-interventional studies (NIS) investigate the features of a therapy in daily clinical practice. The observational plan of NIS does not dictate a treatment strategy, but is based on the product label. Unlike RCT, NIS therefore have no actual inclusion and exclusion criteria, allowing the study of broad heterogeneous patient populations. METHODS: NIS carried out in Germany with support from the pharmaceutical industry and investigating the use of biologics for the treatment of rheumatoid arthritis were identified and their findings were compared with those from the RCT of the respective biologic. RESULTS: Analysis of the identified NIS revealed the following: (1) populations in NIS were on average more than twice as large as in RCT, (2) patient characteristics in NIS and RCT were different, (3) the effectiveness of biologics in NIS was comparable to the efficacy observed in RCT, and (4) NIS collected supplementary data, e.g. on usage and dosing in clinical practice. CONCLUSION: NIS represent an important tool for the assessment of daily clinical practice. Despite methodological drawbacks, NIS provide valuable data that contribute to a more complete picture of the value of treatment with biologics.
