Background: Multimodal rheumatologic complex treatment (MRCT, operation and procedures classification system, OPS code 8‑983) is a specific concept of acute inpatient care (DRG I97Z) for treatment of patients with rheumatic diseases, degenerative diseases and/or chronic pain syndromes suffering from exacerbated pain and functional impairment., Objective: A monocentric retrospective analysis of the effects of MRCT on pain and functional status in patients with rheumatoid arthritis (RA) was conducted., Methods: A total of 103 treatment episodes in 75 patients with proven RA who received MRCT between 2014 and 2017 were included in the analysis. The changes in pain intensity were evaluated using a numerical rating scale (NRS), the functional limitations as assessed by the Hanover function questionnaire (FFbH) and the health assessment questionnaire (HAQ) and the disease activity (disease activity score of 28 joints, DAS28) before and after MRCT episodes. In addition, the patient characteristics and the course of the disease were documented and a univariate analysis of the influence of these factors on the parameters activity and function was performed., Results: In patients with RA, the MRCT resulted in a significant amelioration of pain (p < 0.0001), a significant improvement of functional capacity (FFbH p = 0.0013, HAQ p = 0.1396) and a significant reduction of disease activity (DAS28 p < 0.0001). Different aspects of the disease and its previous course (e. g. disease duration, type and number of previous anti-rheumatic drugs, current medication) did not have a significant effect on the response., Conclusion: This retrospective monocentric analysis proved the efficacy of MRCT with respect to the inpatient treatment period in a large cohort of RA patients. This treatment concept not only improved pain and function (FFbH) but also significantly reduced the disease activity.

The term modern disease-modifying antirheumatic drugs (DMARD) includes not only the constantly growing family of DMARDs for chronic inflammatory rheumatic diseases but also the repositioning of established drugs in updated and novel algorithms of the different entities. The usual precursor for these developments is rheumatoid arthritis for which completely revised and updated guidelines have been published not only in Germany but also on the European level. In addition, label extensions to existing drugs have been granted for connective tissue diseases and vasculitides, e.g. anti-CD20 antibodies for antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitides and belimumab for systemic lupus erythematosus. Moreover, several novel drugs, especially of the biologics class, have been either introduced in clinical rheumatology or are close to being licensed and include ustekinumab for psoriatic arthritis, granulocyte growth inhibitors and janus kinase inhibitors for rheumatoid arthritis and atacicept for systemic lupus erythematosus. With the termination of the patent for several biologics, a new momentum also took place: the approval of the so-called biosimilars which has already initiated intensive discussions not only with respect to "similar" effects and side effects but also with respect to their potential impact on economical aspects.

Introduction: Peripheral arthritis is the most common presenting complaint in clinical rheumatology. Unequivocal identification of the underlying entity can be difficult, particularly at an early stage. Such cases are commonly referred to as undifferentiated peripheral inflammatory arthritis (UPIA). Since evidence-based recommendations for the clinical management of UPIA are lacking, this international 3e initiative convened 697 rheumatologists from 17 countries to develop appropriate recommendations., Methods: Based on a systematic literature research in Medline, EMBASE, Cochrane Library, and the ACR/EULAR abstracts of 2007/2008, 10 multinational recommendations were developed by 3 rounds of a Delphi process. In Germany, a national group of experts worked on 3 additional recommendations using the same method. The recommendations were discussed among the members of the 3e initiative and the degree of consensus was analyzed as well as the potential impact of the recommendations on clinical practice., Results: A total of 39,756 references were identified, of which 250 were systematically reviewed for the development of 10 multinational recommendations concerning differential diagnosis, diagnostic and prognostic value of clinical assessments, laboratory tests and imaging techniques, and monitoring of UPIA. In addition, 3 national recommendations on the diagnostic and prognostic value of a response to anti-inflammatory therapy on the analysis of synovial fluid and on enthesitis were developed by the German experts based on 35 out of 5542 references., Conclusions: The article translates the 2011 published original paper of the international 3e initiative (Machado et al., Ann Rheum Dis 70:15-24, 2011) and reports the methods and results of the national vote and the additional 3 national recommendations.

Rheumatic disease can affect and severely damage vital organs and thus cause acute emergencies and life-threatening complications. As systemic diseases they can cause any presenting complaint commonly encountered in emergency medicine. Because of their relative rarity in general practice, a high level of vigilance is required in order to recognize an emergency caused by an underlying rheumatic disease in individual cases. The most important rheumatological emergencies comprise septic arthritis, gout, atlantoaxial subluxation, renal crisis and digital ulcers in systemic sclerosis, amaurosis fugax in giant cell arteritis, the catastrophic anti-phospholipid antibody syndrome and the pulmonary-renal syndrome. This article provides an overview over these rheumatological emergencies in order to aid recognition of these entities in individual cases and to thus facilitate immediate and adequate treatment, which is of vital importance for affected patients., (Georg Thieme Verlag KG Stuttgart, New York.)

Autoantigen-specific T cells have tissue-specific homing properties, suggesting that these cells may be ideal vehicles for the local delivery of immunoregulatory molecules. We tested this hypothesis by using type II collagen-specific (CII-specific) CD4(+) T hybridomas or primary CD4(+) T cells after gene transfer, as vehicles to deliver an immunoregulatory protein for the treatment of collagen-induced arthritis (CIA), a mouse model of rheumatoid arthritis (RA). CII-specific T cells or hybridomas were transduced using retroviral vectors to constitutively express the IL-12 antagonist, IL-12 p40. Transfer of engineered CD4(+) T cells after immunization significantly inhibited the development of CIA, while cells transduced with vector control had no effect. The beneficial effect on CIA of IL-12 p40-transduced T cells required TCR specificity against CII, since transfer of T cells specific for another antigen producing equivalent amounts of IL-12 p40 had no effect. In vivo cell detection using bioluminescent labels and RT-PCR showed that transferred CII-reactive T-cell hybridomas accumulated in inflamed joints in mice with CIA. These results indicate that the local delivery of IL-12 p40 by T cells inhibited CIA by suppressing autoimmune responses at the site of inflammation. Modifying antigen-specific T cells by retroviral transduction for local expression of immunoregulatory proteins thus offers a promising strategy for treating RA.
