ABSTRACT

Conventional synthetic (cs) and targeted synthetic (ts) disease-modifying antirheumatic drugs (DMARD) have potential interactions with a multitude of drugs. Furthermore, they sometimes have a lower therapeutic index, particularly in cases of limited organ functions. The aim of this work was to establish evidence-based recommendations on the therapeutic use of DMARDs in the context of drug interactions and dosage recommendations. A systematic literature search was carried out on the issue of drug interactions and dosages in cases of patients with limited kidney function and higher age and suffering from rheumatoid arthritis. A total of 2756 scientific publications were screened and 154 selected of which 68 were scrutinized in detail. Furthermore, the respective product information was also analyzed. A multitude of possible interactions of synthetic DMARDs with different drugs were detected, which were then assessed with respect to the clinical significance and consequences. A consensus process led to making recommendations with which the interactions were classified: A: dangerous combination, B: avoid combination (if possible, pausing DMARD treatment), C: possible combination requiring increased monitoring and potential adjustments in dosage and D: pharmacological interaction without relevance in DMARD standard doses. Apart from that dosage recommendations were established for each csDMARD and tsDMARD depending on kidney function and age. There are 3 primary recommendations and 11 core recommendations on interactions and dosages of csDMARDs and tsDMARDs meant as a practical help for therapeutic decision making and to improve safety in the treatment of rheumatoid arthritis.

ABSTRACT

BACKGROUND: Antimalarial medication (AM) plays an important role in the treatment of rheumatic diseases. OBJECTIVE: Updated evidence-based recommendations on the safety management of rheumatological treatment with AM are presented. METHODS: A systematic literature search in the databases Medline (PubMed) and Cochrane identified 1160 studies on the safety of treatment with AM in rheumatology. In addition, a manual search was carried out and 67 publications considered to be particularly relevant by the authors were analyzed in more detail. These publications served as a basis for consensus-based recommendations. RESULTS: Treatment with AM in rheumatology should be carried out with hydroxychloroquine (HCQ) with a dosage not exceeding 5 mg/kg body weight/day. Patients should undergo a basic ophthalmological examination within the first 6 months of AM treatment. Pre-existing maculopathy, renal insufficiency (glomerular filtration rate, GFR <60 ml/min), tamoxifen comedication, a daily dose of >5 mg/kg HCQ or treatment with chloroquine (CQ) show an increased risk for AM-induced retinopathy. These patients should undergo an annual ophthalmological check from the beginning of the treatment, whereas patients with no risk factors are recommended to start this only after 5 years of taking the medication. The ophthalmological examination should comprise at least both an appropriate subjective and an objective method and these are usually an automated visual field test and optical coherence tomography (OCT). A visual field test revealing a parafoveal sensitivity loss and an OCT showing a parafoveal circumscribed loss of the photoreceptor layer or focal interruptions of the structural line of the outer segment are signs of a possible AM retinopathy. Determination of creatine kinase (CK) and lactate dehydrogenase (LDH) in blood is appropriate to screen for cardiomyopathy and myopathy and should be checked before starting the treatment and then ca. every 3 months. The use of cardiac biomarkers, such as brain natriuretic peptide (BNP) or troponin in serum, electrocardiograph (ECG) or cardiac imaging should be considered depending on the situation. An intake of HCQ is safe during pregnancy and breastfeeding according to the current state of knowledge and is protective for mother and child in patients with systemic lupus erythematosus. CONCLUSION: The updated recommendations on AM treatment in rheumatology in particular include a more rigorous measuring of doses, risk stratification in monitoring and defined ophthalmological examination methods to detect a possible retinopathy.

ABSTRACT

BACKGROUND: Familial Mediterranean fever (FMF) is a genetic disease of childhood and adulthood which is relatively rare in Germany. It is characterized by recurrent febrile attacks, peritonitis, pleuritis and arthritis. The established treatment with colchicine is effective and well-tolerated by most patients; however, some patients do not adequately respond or do not tolerate this treatment. Biologics can be considered for some of these patients. The Society for Pediatric and Adolescent Rheumatology (GKJR) and the German Society for Rheumatology (DGRh) have agreed to develop joint recommendations for this specific clinical situation. AIM: Implementation of a systematic literature search (SLR) on the basis of the EULAR recommendations published in 2016 as the foundation for the development of evidence-based treatment recommendations for FMF patients with insufficient response or intolerance to colchicine. METHODS: The SLR was performed using references from various databases as an update of the SLR carried out by EULAR up to 2014, whereby all articles must have been published between 1 January 2015 and 31 December 2017. The Rayyan abstract tool for the preselection and the classification of the Oxford Centre for Evidence Based Medicine 2009 were used for the preparation of the evidence tables. RESULTS: The search yielded 360 hits and after duplicate matching 263. A total of 88 publications were included (34%) and 102 excluded (39%), a review of the full publication was necessary for a further 73 (28%) and 43 were discussed more intensively. Finally, 64 publications (24%) remained. A total of 4 case-control studies, 31 cohort studies, 8 case series, 7 controlled studies (including 5 abstracts), 10 reviews, 4 meta-analyses and systematic reviews were accepted. DISCUSSION: The SLR was carried out in a scientifically accurate and transparent manner according to international standards. The SLR proved to be a good basis for a consensus on the 5 overarching principles and the 10 recommendations, so that the joint activity of the GKJR and DGRh was successfully and even promptly concluded. The recommendations are a solid basis for treating patients of all ages with FMF. The explanations on the problem of colchicine resistance play an important role here.

ABSTRACT

BACKGROUND: Familial Mediterranean fever (FMF) in Germany is a rare, genetically linked disease of childhood and adolescence, which is characterized by recurrent febrile episodes and clinical signs of peritonitis, pleuritis and arthritis. Treatment with colchicine is effective and well-tolerated in the majority of patients; however, some patients do not sufficiently respond to this treatment or are intolerant to colchicine. For these patients first-line treatment with biologics which block interleukin-1 can be used. OBJECTIVE: The aim was to formulate evidence-based treatment recommendations for patients with an insufficient response and intolerance to colchicine treatment. METHODS: Based on a literature search and the European League Against Rheumatism (EULAR) recommendations on FMF from 2016 the appointed members of the Society for Pediatric and Adolescent Rheumatology (GKJR) and the German Society for Rheumatology (DGRh) convened to work out and form a consensus in a joint statement on evidence-based treatment recommendations on FMF. RESULTS: After intensive discussions all decisions were in concordance. A total of 5 superordinate principles and 10 recommendations were agreed upon. DISCUSSION: The joint activities of the GKJR and the DGRh were successfully concluded in a timely manner. The recommendations form a good basis for optimal treatment of all age groups of patients with FMF.

ABSTRACT

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.

ABSTRACT

Polymyalgia rheumatica (PMR) occurs almost exclusively in persons aged 50 years or older and it is the second most common inflammatory rheumatic disease in older people after rheumatoid arthritis. Since there are no specific tests for PMR, the exclusion of clinically similar differential diagnoses is essential to ascertain the diagnosis. These recommendations for the management of PMR assume an already established diagnosis of PMR. It is recommended to initiate treatment with glucocorticoids immediately after diagnosis and to provide appropriate patient information and education about the impact of the disease and its treatment. Methotrexate should be considered in patients at high risk for relapse and/or glucocorticoid-related adverse events. These guidelines have been elaborated because there is significant heterogeneity in the management of PMR in clinical practice in Germany (but also Europe and worldwide), despite the large number of patients with this disease. These guidelines are primarily based on the 2015 EULAR-ACR recommendations for the management of PMR, which were updated by the guideline committee and adapted to the German speaking countries.
