Safety of low dose glucocorticoid treatment in rheumatoid arthritis: published evidence and prospective trial data

Adverse effects of glucocorticoids have been abundantly reported. Published reports on low dose glucocorticoid treatment show that few of the commonly held beliefs about their incidence, prevalence, and impact are supported by clear scientific evidence. Safety data from recent randomised controlled clinical trials of low dose glucocorticoid treatment in RA suggest that adverse effects associated with this drug are modest, and often not statistically different from those of placebo

“Come and live with my feet and you’ll understand”–a qualitative study exploring the experiences of retail footwear in women with rheumatoid arthritis

Background: Foot pain and deformity are common in people with rheumatoid arthritis (RA). Previous research has identified that women with RA seek retail footwear to alleviate their foot problems. The specific footwear features that women with RA require, and what would help them to find shoes that meet these requirements, are unknown. This study aimed to determine the factors that influence the choice of appropriate retail footwear by women with RA. Method: An overarching qualitative approach was taken, using reflexive thematic analysis of conversational style interviews. The interviews explored experiences and use of retail footwear in 20 women with RA. The interviews were digitally recorded transcribed verbatim and analysed using a reflexive thematic framework. Results: Women with RA sought retail footwear which had adequate cushioning, width, a flexible sole, lightweight, were made from breathable materials and were easy to put on and take off. However, this choice was driven by the need for comfort, cost and usability, with aesthetics being less of a priority. Despite having opinions on what criteria they felt that they needed, these women did not feel empowered to make good choices about purchasing retail footwear for symptomatic relief. Furthermore, they did not receive the necessary support from podiatrists and shoe shop staff. Conclusion: Women with RA have clear ideas about what features a retail shoe should have to achieve comfort. There is a constant compromise between achieving comfort and their feelings about their appearance and how they feel others perceive them. Women with RA describe negative experiences with shoe shop assistants and podiatrists leading to poor footwear choices. Both retail staff and podiatrists need increased understanding about the particular problems that women with RA experience. Keywords: Footwear, Rheumatoid arthritis, Thematic analysi

A pilot study of IL-1 inhibition by anakinra in acute gout

Monosodium urate crystals stimulate monocytes and macrophages to release IL-1β through the NALP3 component of the inflammasome. The effectiveness of IL-1 inhibition in hereditary autoinflammatory syndromes with mutations in the NALP3 protein suggested that IL-1 inhibition might also be effective in relieving the inflammatory manifestations of acute gout. The effectiveness of IL-1 inhibition was first evaluated in a mouse model of monosodium urate crystal-induced inflammation. IL-1 inhibition prevented peritoneal neutrophil accumulation but TNF blockade had no effect. Based on these findings, we performed a pilot, open-labeled study (trial registration number ISRCTN10862635) in 10 patients with gout who could not tolerate or had failed standard antiinflammatory therapies. All patients received 100 mg anakinra daily for 3 days. All 10 patients with acute gout responded rapidly to anakinra. No adverse effects were observed. IL-1 blockade appears to be an effective therapy for acute gouty arthritis. The clinical findings need to be confirmed in a controlled study

Current and emerging treatment of osteoporosis

The goal of treating a patient with recent fragility fracture should not only be to treat the patient in the acute phase but also to prevent further fractures. Interventions to increase bone mass to preventing further fragility fractures can be classified as non-pharmacological and pharmacological. All European and international guidelines base the need for treatment, not on the diagnosis of osteoporosis (based on the T-score), but on the risk of fracture, which is strongly influenced by the presence of a fragility fracture, especially vertebral or femoral fractures. Before treatment, it is important to make a differential diagnosis between primary and secondary osteoporosis because anti-osteoporotic drug treatment would be useless if the primary illness causing osteoporosis is not treated too. Some studies show that anti-osteoporotic drugs are frequently interrupted within 1 month of their prescription; this happens not so much due to the occurrence of adverse events but mostly because patients have not been sufficiently informed about the importance of taking the drug and because are not receiving personalised treatment. All data confirm that, in older people, vitamin D deficiency is highly prevalent and calcium intake is often not adequate. So, osteoporosis guidelines recommend calcium and vitamin D for all patients in association with antiosteoporotic therapy. We have many drugs for the treatment of patients at high risk of fracture, but we should use drugs based on evidence of their efficacy and safety in older-age subgroups, provided by targeted studies or extrapolated data. In this chapter, we describe efficacy, route of administration, adverse events and recent technical remarks of current antiresorptive and anabolic osteoporosis therapies. Furthermore, we describe emerging therapies, such as Abaloparatide and Romosozumab

Advances in Glucocorticoid-Induced Osteoporosis

Glucocorticoid-induced osteoporosis (GIOP) is one of the most important side effects of glucocorticoid use, as it leads to an increased risk of fractures. Recently, many published studies have focused on the cellular and molecular mechanisms of bone metabolism, the pathophysiology of GIOP, and the intervention options to prevent GIOP. In this review, recent advances in GIOP are summarized, particularly recent progress in our understanding of the mechanisms of GIOP resulting in improved insight that might result in the development of new treatment options in the near future

Pharmacokinetics of Teriparatide (rhPTH[1–34]) and Calcium Pharmacodynamics in Postmenopausal Women with Osteoporosis

Teriparatide (rhPTH[1–34]) affects calcium metabolism in a pattern consistent with the known actions of endogenous parathyroid hormone (PTH). This report describes the pharmacokinetics and resulting serum calcium response to teriparatide in postmenopausal women with osteoporosis. Pharmacokinetic samples for this analysis were obtained from 360 women who participated in the Fracture Prevention Trial. Postmenopausal women with osteoporosis received daily subcutaneous injections of either teriparatide 20 μg (4.86 μmol) or placebo, median 21 months’ treatment. Serum teriparatide and calcium concentrations were measured throughout the study. An indirect-response model was developed to describe the pharmacokinetic–pharmacodynamic relationship between teriparatide concentrations and serum calcium response. The pharmacokinetics of teriparatide were characterized by rapid absorption (maximum concentration achieved within 30 min) and rapid elimination (half-life of 1 h), resulting in a total duration of exposure to the peptide of approximately 4 h. Teriparatide transiently increased serum calcium, with the maximum effect observed at approximately 4.25 h (median increase 0.4 mg/dl [0.1 mmol/l]). Calcium concentrations returned to predose levels by 16–24 h after each dose. Persistent hypercalcemia was not observed; one teriparatide 20 μg-treated patient had a predose serum calcium value above the normal range but <11.0 mg/dl (2.75 mmol/l). Following once-daily subcutaneous administration, teriparatide produces a modest but transient increase in serum calcium, consistent with the known effects of endogenous PTH on mineral metabolism. The excursion in serum calcium is brief, due to the short length of time that teriparatide concentrations are elevated

“Clinical features of women with gout arthritis.” A systematic review

Clinically, gout is generally considered as a preferential male disease. However, it definitely does not occur exclusively in males. Our aim was to assess differences in the clinical features of gout arthritis between female and male patients. Five electronic databases were searched to identify relevant original studies published between 1977 and 2007. The included studies had to focus on adult patients with primary gout arthritis and on sex differences in clinical features. Two reviewers independently assessed eligibility and quality of the studies. Out of 355 articles, 14 were selected. Nine fulfilled the quality and score criteria. We identified the following sex differences in the clinical features of gout in women compared to men: the onset of gout occurs at a higher age, more comorbidity with hypertension or renal insufficiency, more often use of diuretics, less likely to drink alcohol, less often podagra but more often involvement of other joints, less frequent recurrent attacks. We found interesting sex differences regarding the clinical features of patients with gout arthritis. To diagnose gout in women, knowledge of these differences is essential, and more research is needed to understand and explain the differences , especially in the general population

Non-operative management of posterior tibialis tendon dysfunction: design of a randomized clinical trial [NCT00279630]

BACKGROUND: Posterior tibialis tendon dysfunction (PTTD) is a common cause of foot pain and dysfunction in adults. Clinical observations strongly suggest that the condition is progressive. There are currently no controlled studies evaluating the effectiveness of exercise, orthoses, or orthoses and exercise on Stage I or IIA PTTD. Our study will explore the effectiveness of an eccentric versus concentric strengthening intervention to results obtained with the use of orthoses alone. Findings from this study will guide the development of more efficacious PTTD intervention programs and contribute to enhanced function and quality of life in persons with posterior tibialis tendon dysfunction. METHODS/DESIGN: This paper presents the rationale and design for a randomized clinical trial evaluating the effectiveness of a treatment regime for the non-operative management of Stage I or IIA PTTD. DISCUSSION: We have presented the rationale and design for an RCT evaluating the effectiveness of a treatment regimen for the non-operative management of Stage I or IIA PTTD. The results of this trial will be presented as soon as they are available
