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

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

BACKGROUND: Long-term treatment with glucocorticoids (GCs) plays an important role in the management of arthritis patients, although the efficacy/safety balance is unfavorable. Alternatives with less (severe) adverse effects but with good efficacy are needed. Selective GC receptor modulators (SGRMs) are designed to engage the GC receptor with dissociative characteristics: transactivation of genes, which is mainly responsible for unwanted effects, is less strong while trans-repression of genes, reducing inflammation, is maintained. It is expected that SGRMs thus have a better efficacy/safety balance than GCs. A systematic review providing an overview of the evidence in arthritis is lacking. OBJECTIVE: To systematically review the current literature on efficacy and safety of oral SGRMs in comparison to GCs in arthritis. METHODS: A search was performed in Medline, Embase and the Cochrane Library, from inception dates of databases until May 2017. Experimental studies involving animal arthritis models or human material of arthritis patients, as well as clinical studies in arthritis patients were included, provided they reported original data. All types of arthritis were included. Data was extracted on the SGRM studied and on the GC used as reference standard; the design or setting of the study was extracted as well as the efficacy and safety results. RESULTS: A total of 207 articles was retrieved of which 17 articles were eligible for our analysis. Two studies concerned randomized controlled trials (RCT), five studies were pre-clinical studies using human material, and 10 studies involved pre-clinical animal models (acute and/or chronic arthritis induced in mice or rats). PF-04171327, the only compound investigated in a clinical trial setting, had a better efficacy/safety balance compared to GCs: better clinical anti-inflammatory efficacy and similar safety. CONCLUSION: Studies assessing both efficacy and safety of SGRMs are scarce. There is limited evidence for dissociation of anti-inflammatory and metabolic effects of the SGRMs studied. Development of many SGRMs is haltered in a preclinical phase. One SGRM showed a better clinical efficacy/safety balance.

RESUMEN

A new strategy to improve osseointegration of implants is to stimulate adhesion of bone cells, bone matrix formation, and mineralization at the implant surface by modifying surface coating on the nanoscale level. Plant-derived pectins have been proposed as potential candidates for surface nanocoating of orthopedic and dental titanium implants due to 1) their osteogenic stimulation of osteoblasts to mineralize and 2) their ability to control pectin structural changes. The aim of this study was to evaluate in vitro the impact of the nanoscale plant-derived pectin Rhamnogalacturonan-I (RG-I) from potato on the osteogenic response of murine osteoblasts. RG-I from potato pulps was isolated, structurally modified, or left unmodified. Tissue culture plates were either coated with modified RG-I or unmodified RG-I or - as a control - left uncoated. The effect of nanocoating on mice osteoblast-like cells MC3T3-E1 and primary murine osteoblast with regard to proliferation, osteogenic response in terms of mineralization, and gene expression of Runt-related transcription factor 2 (Runx2), alkaline phosphate (Alpl), osteocalcin (Bglap), α-1 type I collagen (Col1a1), and receptor activator of NF-κB ligand (Rankl) were analyzed after 3, 7, 14, and 21 days, respectively. Nanocoating with pectin RG-Is increased proliferation and mineralization of MC3T3-E1 and primary osteoblast as compared to osteoblasts cultured without nanocoating. Moreover, osteogenic transcriptional response of osteoblasts was induced by nanocoating in terms of gene induction of Runx2, Alpl, Bglap, and Col1a1 in a time-dependent manner - of note - to the highest extent under the PA-coating condition. In contrast, Rankl expression was initially reduced by nanocoating in MC3T3-E1 or remained unaltered in primary osteoblast as compared to the uncoated controls. Our results showed that nanocoating of implants with modified RG-I beneficially 1) supports osteogenesis, 2) has the capacity to improve osseointegration of implants, and is therefore 3) a potential candidate for nanocoating of bone implants.

RESUMEN

The initial inflammatory phase of fracture healing is of great importance for the clinical outcome. We aimed to develop a detailed time-dependent analysis of the initial fracture hematoma. We analyzed the composition of immune cell subpopulations by flow cytometry and the concentration of cytokines and chemokines by bioplex in 42 samples from human fractures of long bones <72 h post-trauma. The early human fracture hematoma is characterized by maturation of granulocytes and migration of monocytes/macrophages and hematopoietic stem cells. Both T helper cells and cytotoxic T cells proliferate within the fracture hematoma and/or migrate to the fracture site. Humoral immunity characteristics comprise high concentration of pro-inflammatory cytokines such as IL-6, IL-8, IFNγ and TNFα, but also elevated concentration of anti-inflammatory cytokines, e.g., IL-1 receptor antagonist and IL-10. Furthermore, we found that cells of the fracture hematoma represent a source for key chemokines. Even under the bioenergetically restricted conditions that exist in the initial fracture hematoma, immune cells are not only present, but also survive, mature, function and migrate. They secrete a cytokine/chemokine cocktail that contributes to the onset of regeneration. We hypothesize that this specific microenvironment of the initial fracture hematoma is among the crucial factors that determine fracture healing.

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

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: 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

Glucocorticoids have potent anti-inflammatory and immunomodulatory effects and are widely use in the management of rheumatoid arthritis in combination with other synthetic and with biological disease-modifying anti-rheumatic drugs. Concerns about the risk of adverse effects of glucocorticoids, especially if they are given at higher dosages and for a longer time, hamper their use despite the clear symptomatic and disease modifying benefits. However, the evidence base for these concerns for low dose glucocorticoid therapy is quite limited due to the scarcity of quality literature on its safety in rheumatoid arthritis. This review discusses the current understanding about their disease-modifying effects, toxicity data from recent trials and observational studies, recommendations for their management and the current efforts to improve the therapeutic ratio of glucocorticoid through the development of new formulations, such as modified-release prednisone.

RESUMEN

OBJECTIVE: Little is known about the relationship between morning symptoms of rheumatoid arthritis (RA) and measures of disease activity currently used to assess RA. Information available from the Circadian Administration of Prednisone in Rheumatoid Arthritis (CAPRA-2) study was used to investigate these relationships. METHODS: CAPRA-2 included 350 patients with RA who were symptomatic despite treatment with disease-modifying antirheumatic drugs, randomized 2:1 to additional treatment with a 5-mg daily dose of delayed-release prednisone or placebo. Pearson's correlations were used to evaluate the relationships between change from baseline in symptoms (duration of morning stiffness, severity of morning stiffness, and intensity of pain on waking) and measures of disease activity (the American College of Rheumatology 20% improvement criteria [ACR20], the Disease Activity Score in 28 joints [DAS28], and the Health Assessment Questionnaire disability index). Correlations were defined as weak (<0.3), moderate (0.3-0.7), or strong (>0.7). RESULTS: There was a strong correlation between the severity of morning stiffness and the intensity of morning pain (Pearson's correlation 0.91, P < 0.001). There was a weak correlation between the duration of morning stiffness and measures of disease activity (0.24-0.28), with moderate correlations between the severity of morning stiffness or intensity of pain on waking and DAS28 or ACR20 scores (0.44-0.48). Severity of morning stiffness showed less variability and a greater effect size than did duration of morning stiffness. CONCLUSION: Morning symptoms and measures of disease activity show weak to moderate correlations. Severity of morning stiffness showed less variability and greater effect size than did duration of morning stiffness. These findings suggest that severity is the preferred construct to measure the impact of morning stiffness in patients with RA, information that is not fully captured in the RA core set.
