RESUMEN

OBJECTIVE: To evaluate the current perspectives of patients and health professionals regarding the efficacy and safety of low-dose glucocorticoids (GCs) in RA. METHODS: Two online surveys were disseminated to patients and health professionals, in their native language, through national patient organizations and national rheumatology medical societies, respectively. SurveyMonkey®, MediGuard.org and the Glucocorticoid Low-dose Outcome in RA Study (GLORIA) website were used to offer and deliver these surveys. RESULTS: A total of 1221 RA patients with exposure to GCs, and 414 rheumatologists completed the surveys. Patients and rheumatologists reported high levels of agreement regarding the efficacy of low-dose GCs: at least 70% considered that they are very rapid and effective in the control of signs and symptoms of RA. However, half of the patients also reported having suffered serious adverse events with GCs, and 83% described concerns about safety. The majority of rheumatologists estimated that endocrine, ophthalmologic and cutaneous adverse events affect >4% of all patients treated with low-dose GCs for 2 years, based on a heat map. CONCLUSIONS: RA patients with self-reported exposure to GCs express high levels of satisfaction with low-dose GCs efficacy, as do rheumatologists. However, both expressed excessive concerns regarding the safety of GCs (greatly exceeding the published evidence data), which may compromise the optimal use of this medication. This study indicates that there is an unmet need for appropriately designed prospective trials that shed light on the real risk associated with low-dose GCs, as well as a need for renovated educational programs on the real benefits and harms of low-dose GCs, for both patients and physicians.

RESUMEN

Glucocorticoids (GC) have been proven drug substances in rheumatology for more than 70 years. They act very rapidly in high doses through membrane stabilizing effects. Genomic therapeutic effects of GC even in very low doses are mainly due to inhibition of the functions of the transcription factor nuclear factor kappa B (NFkB), which promotes the synthesis of proinflammatory mediators, adhesion molecules and other regulatory proteins. Indications for the use of GC in high doses in rheumatology are always given when a life-threatening, dangerous or treatment-resistant situation is involved. Lower doses of GC, usually administered orally, are particularly used in rheumatoid arthritis, vasculitis and collagenosis. In clinical practice the general principle is to use the smallest possible effective dose of GC for the shortest possible time in order to achieve the therapeutic effect of GC without running the risk of unacceptably severe side effects.

RESUMEN

BACKGROUND: Infections are one of the most common clinical problems in patients with rheumatic diseases who need to be treated with glucocorticoids in an intensive care unit. To date, there are no recommendations for the standardized control of glucocorticoid treatment in such situations. OBJECTIVE: Based on a literature search this paper provides an overview of evidence-based and eminence-based recommendations for the control of glucocorticoid treatment under intensive care conditions using the example of systemic lupus erythematosus. METHODS: A systematic literature search was carried out using a MeSH term search in the PubMed database. RESULTS: Infections are one of the most common causes for the treatment of patients with rheumatic diseases in intensive care units. In the case of systemic lupus erythematosus it is particularly challenging to distinguish the infection from increased disease activity or to treat the parallel occurrence. Patients in an intensive care unit are exposed to an increased level of physical stress due to the severity of the disease, which is why special attention should be paid to symptoms of adrenocortical insufficiency. Evidence-based recommendations for prophylaxis of an adrenal crisis only exist in relation to perioperative procedures and not for the situation of severe infections. CONCLUSION: The use of glucocorticoids in systemic lupus erythematosus is often chronic and there is an increased risk of infections. In the case of infections (or simultaneous disease flare) adequate anti-infective treatment should be administered, the treatment with glucocorticoids should be adjusted accordingly and symptoms of adrenocortical insufficiency should simultaneously be looked for.

RESUMEN

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.

RESUMEN

Polymyalgia rheumatica (PMR) is the most common autoimmune inflammatory disease in older persons with an average age of onset of 73 years. Typical symptoms include acute or subacute bilateral shoulder pain with severe stiffness and often neck and bilateral hip pain. Giant cell arteritis (GCA) occurs in approximately 20 % of cases and up to two thirds of patients with GCA have symptoms of PMR. There are many disease which mimic PMR, elderly onset rheumatoid arthritis is frequently misdiagnosed as PMR. Although there are no specific laboratory tests, C­reactive protein and erythrocyte sedimentation rates are elevated in over 90 % of patients. The diagnosis may be aided by imaging, especially ultrasonography and magnetic resonance imaging (MRI). Treatment currently consists of glucocorticoids at an initial dose of 12.5-25 mg prednisone equivalent daily. Treatment duration is typically 2­3 years but may be longer. Under certain conditions low-dose methotrexate can be used as adjuvant therapy.

RESUMEN

Glucocorticoids have been successfully used for a long time to treat a wide range of chronic inflammatory diseases. Despite the well-accepted efficacy, possible adverse effects still provoke discussions among patients and physicians. In particular, the long-term use of glucocorticoids at higher dosages may cause unwanted adverse effects; therefore, the question arises if conditions for a safe long-term treatment regimen with these drugs can be defined. Studies specifically and comprehensively addressing this question are missing; therefore, a multidisciplinary task force comprised of medical experts and patients was formed to analyze and discuss the existing literature in order to identify conditions where long-term glucocorticoid treatment has an acceptably low level of harm. The group agreed that the actual level of harm of long-term glucocorticoid therapy depends on both drug (dose and duration) and patient-specific characteristics. The patient-specific parameters (some of which can be modified by patients and/or physicians) should always be monitored before and during treatment with glucocorticoids and optimized if necessary. A positive benefit-risk ratio can be achieved when current knowledge and existing recommendations are kept in mind and implemented in clinical practice.

RESUMEN

OBJECTIVE: To assess morning stiffness in rheumatoid arthritis (RA) patients switched from immediate-release (IR) to delayed-release (DR) prednisone. METHOD: Circadian Administration of Prednisone in Rheumatoid Arthritis-1 (CAPRA-1) is a 12-week, randomized, multicentre, active-controlled study of morning stiffness that consisted of a double-blind phase and a 9-month open-label extension. Patients receiving IR prednisone with no significant improvement after the double-blind study were switched to DR prednisone. Morning stiffness duration and median absolute and relative changes in pain and global assessment were evaluated (3, 6, and 9 months). RESULTS: In patients switched from IR to DR prednisone (n=110), statistically significant reductions in morning stiffness occurred over 3 months and were sustained for 9 months. Absolute reduction of morning stiffness was ~50 min with >40% relative reduction at each visit. Interleukin (IL)-6 levels were reduced by the same amount. Statistically significant and clinically meaningful mean reductions in morning stiffness were maintained at >67 min at each visit along with significant improvements in pain and patient global assessment. There was no evidence of tachyphylaxis seen over the 9-month study. CONCLUSIONS: Patients receiving disease-modifying anti-rheumatic drugs (DMARDs) and IR prednisone who had not had significant reductions in morning stiffness demonstrated statistically significant and clinically meaningful improvements when switched to DR prednisone.

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

To develop recommendations for the management of medium to high-dose (ie, >7.5 mg but ≤100 mg prednisone equivalent daily) systemic glucocorticoid (GC) therapy in rheumatic diseases. A multidisciplinary EULAR task force was formed, including rheumatic patients. After discussing the results of a general initial search on risks of GC therapy, each participant contributed 10 propositions on key clinical topics concerning the safe use of medium to high-dose GCs. The final recommendations were selected via a Delphi consensus approach. A systematic literature search of PubMed, EMBASE and Cochrane Library was used to identify evidence concerning each of the propositions. The strength of recommendation was given according to research evidence, clinical expertise and patient preference. The 10 propositions regarded patient education and informing general practitioners, preventive measures for osteoporosis, optimal GC starting dosages, risk-benefit ratio of GC treatment, GC sparing therapy, screening for comorbidity, and monitoring for adverse effects. In general, evidence supporting the recommendations proved to be surprisingly weak. One of the recommendations was rejected, because of conflicting literature data. Nine final recommendations for the management of medium to high-dose systemic GC therapy in rheumatic diseases were selected and evaluated with their strengths of recommendations. Robust evidence was often lacking; a research agenda was created.

RESUMEN

UNLABELLED: The bone mineral density (BMD) measurement of the hand in rheumatoid arthritis (RA) patients is no standard measurement method as yet. The aim was to contribute to the standardization of the hand BMD measurement, especially of periarticular regions. As results, we found best precision values for the wrist and a significant correlation between hand and spine/femur BMD depending on disease activity and disease duration. INTRODUCTION: This study was conducted to investigate (i) the precision of periarticular hand BMD measuring, (ii) the periarticular demineralization of the hand, (iii) the correlation between periarticular hand BMD and spine/femur BMD, and (iv) the correlation of hand BMD to hand synovitis. METHODS: A number of 52 RA patients were examined by BMD measurement of the femoral neck, spine, whole hand, metacarpophalangeal (MCP) joints II-V, personal identity profile (PIP) joints II-V, and wrist using dual-energy X-ray absorptiometry (DXA). Synovitis of the hand was examined by ultrasonography and magnetic resonance imaging (MRI). Three subgroups were further analyzed: early RA, established RA with moderate and with high disease activity. Early RA and established RA patients with high disease activity were Followed up after 12 months. RESULTS: We found (1) best precision of BMD measurement for the wrist, (2) BMD in RA significantly reduced if compared to normal controls, (3) a highly significant positive correlation between hand and spine/femur BMD and the power of correlation to depend on disease activity and disease duration (high correlation in RA with moderate disease activity and early RA, very high correlation in RA with high disease activity), (4) a negative correlation between hand BMD and hand synovitis in RA with high disease activity, and (5) a significant reduction of synovitis but no change in hand BMD after 12 months, respectively. CONCLUSIONS: This study shows a highly significant correlation between hand BMD and spine/femur BMD in RA patients depending on disease activity and disease duration. We conclude to measure BMD at different sites including hands in order to quantify bone loss in RA patients most properly.

RESUMEN

Chronic inflammatory diseases are characterized by hypoxia and subsequent cellular adaptation via hypoxia-inducible factor (HIF). Modulation of these adaptation mechanisms provides the basis for ideas on how to improve the effects of known drugs and for the development of novel therapeutic approaches.

RESUMEN

BACKGROUND: The GLORIA placebo-controlled trial found a favorable balance of benefit and harm for two years of prednisolone (5 mg/day) as add-on treatment for rheumatoid arthritis (RA) patients aged 65+. This study evaluated the cost-effectiveness of low-dose prednisolone in the treatment of RA. METHODS: The economic evaluation had a societal perspective with a time horizon of two years. Cost data were collected with questionnaires and from recorded events, and valued with standard Dutch unit prices of 2017. The primary effectiveness outcome was the disease activity score in 28 joints (DAS28). For cost-utility, quality-adjusted life years (QALYs) were estimated from the EuroQol-5 Dimension (EQ-5D) questionnaire. Bootstrapping assessed the uncertainty around the average differences in costs and health outcomes. RESULTS: In total, 444 of 451 randomized patients were included in the modified intention-to-treat analysis. Patients had median four active comorbidities at baseline. Mean total costs over two years were k€10.8 in the prednisolone group, k€0.5 (95% CI -4.0; 1.8) lower than in the placebo group. Total direct medical costs were k€0.5 (95% CI -4.0; 1.5) lower in the prednisolone group. The mean number of QALYs was similar in both groups (difference 0.02 [-0.03; 0.06] in favor of prednisolone). The DAS28 was 0.38 lower in the prednisolone group than in the placebo group (0.19; 0.56). CONCLUSION: With greater effectiveness (DAS28) at non-significantly lower costs, low-dose, add-on prednisolone is cost-effective for RA compared to placebo over two years. QALYs were equal in both groups, most likely due to the impact of multiple comorbidities.

RESUMEN

e assumption that mesenchymal stromal cell (MSC)-based-therapies are capable of augmenting physiological regeneration processes has fostered intensive basic and clinical research activities. However, to achieve sustained therapeutic success in vivo, not only the biological, but also the mechanical microenvironment of MSCs during these regeneration processes needs to be taken into account. This is especially important for e.g., bone fracture repair, since MSCs present at the fracture site undergo significant biomechanical stimulation. This study has therefore investigated cellular characteristics and the functional behaviour of MSCs in response to mechanical loading. Our results demonstrated a reduced expression of MSC surface markers CD73 (ecto-5'-nucleotidase) and CD29 (integrin ß1) after loading. On the functional level, loading led to a reduced migration of MSCs. Both effects persisted for a week after the removal of the loading stimulus. Specific inhibition of CD73/CD29 demonstrated their substrate dependent involvement in MSC migration after loading. These results were supported by scanning electron microscopy images and phalloidin staining of actin filaments displaying less cell spreading, lamellipodia formation and actin accumulations. Moreover, focal adhesion kinase and Src-family kinases were identified as candidate downstream targets of CD73/CD29 that might contribute to the mechanically induced decrease in MSC migration. These results suggest that MSC migration is controlled by CD73/CD29, which in turn are regulated by mechanical stimulation of cells. We therefore speculate that MSCs migrate into the fracture site, become mechanically entrapped, and thereby accumulate to fulfil their regenerative functions.

RESUMEN

The central nervous biological CLOCK system (highly conserved and sophisticated molecular 'clock'), under the influence of light/dark alterations, 'creates' the internal circadian rhythms. The organisms 'feel' these rhythmic external changes to synchronise their physical activities, including energy metabolism, sleep, and immune function. A number of immunological functions are dependent on influence of sleep on circadian rhythms, including the type and magnitude of immune responses following antigenic challenge. Loss of sleep, in turn, prevents these immunosupportive actions and alters the production of glucocorticoids during the night. Major life events lead to an intense release of stress response system mediators (mainly norepinephrine and cortisol), whereas in minor life events, only short-lived surges of these neurotransmitters and hormones are expected. The immune system reactivity follows circadian rhythms imposed by the CLOCK and sleep synchronisation, and is particularly altered in presence of chronic stress. As a consequence of the altered CNS-endocrine control, low-dose long-term glucocorticoid therapy in chronic rheumatic diseases is today considered as a 'hormonal replacement therapy' to supplement the peripheral insufficiency of endogenous glucocorticoids in modulating the immune/inflammatory reaction.

RESUMEN

The investigation of the hypothalamicpituitary-adrenal (HPA) axis in chronic inflammation has demonstrated: 1) an anti-inflammatory influence of the HPA axis; 2) low serum levels of adrenal androgen; 3) equivocal results with respect to levels of adrenocorticotropic hormone and cortisol; 4) inadequately low secretion of adrenal hormones in relation to inflammation (the disproportion principle); 5) modulating role of TNF and IL-6 on the HPA axis; 6) disturbed cooperativity of HPA axis and sympathetic nervous system (uncoupling); 7) observable glucocorticoid resistance; 8) the circadian rhythmicity explains morning symptoms; 9) new medications based on malfunction of the HPA axis (e.g. adapted to the circadian rhythm of hormones and cytokines); and 10) the newly described role of the HPA axis in the context of misguided energy regulation in chronic inflammatory diseases. This review discusses items 1-6 and 10, while the other items are presented elsewhere in this Supplement. Evidence is presented that the basis for many alterations is in an adaptive program positively selected for short-lived inflammatory responses (energy appeal reaction), which becomes a disease-inherent pathogenetic factor, if it continues too long, that can drive systemic disease sequelae of chronic inflammatory diseases such as the metabolic syndrome.
