Ten-year fracture risk in Japanese patients with myasthenia gravis: A comprehensive assessment using the fracture risk assessment tool

BACKGROUND

Myasthenia gravis (MG) is an immune disorder that causes muscle weakness with an increasing prevalence, particularly among the elderly in Japan. Glucocorticoid treatment for MG is problematic for bone health because of reduced bone density and increased fracture risk. The fracture risk assessment tool (FRAX®) can estimate fracture risk, but its applicability in patients with MG remains uncertain.

METHODS

A prospective cohort study was conducted on 54 patients with MG between April and July 2012. Bone mineral density (BMD) was measured, and FRAX® scores were calculated with and without BMD. We also adjusted FRAX® scores based on glucocorticoid dosage. Patients were monitored for major osteoporotic fractures (MOF) until June 2022. Statistical analyses included Kaplan-Meier curves and Cox proportional hazards models.

RESULTS

The study group included 12 men and 42 women with a mean age of 62 years. Higher FRAX® scores correlated with increased fracture risk, particularly in the hip and lumbar regions. The 10-year fracture-free rate was significantly lower in the high-FRAX® score group. The FRAX® score using BMD is a significant predictor of MOF risk. The hazard ratio for FRAX® scores was 1.17 (95% CI 1.10-1.26).

CONCLUSION

We demonstrated the effectiveness of the FRAX® tool in assessing fracture risk among patients with MG. High FRAX® scores correlated with increased fracture risk, emphasizing its importance. These findings support the incorporation of FRAX® assessment into clinical management to enhance patient care and outcomes. However, the small sample size and observational nature suggest a need for further research.

Bisphosphonate alternative regimens for the prevention of osteoporotic fragility fractures: BLAST-OFF, a mixed-methods study

Background

Bisphosphonates are a class of medication commonly used to treat osteoporosis. Alendronate is recommended as the first-line treatment; however, long-term adherence (both treatment compliance and persistence) is poor. Alternative bisphosphonates are available, which can be given intravenously and have been shown to improve long-term adherence. However, the most clinically effective and cost-effective alternative bisphosphonate regimen remains unclear. What is the most cost-effective bisphosphonate in clinical trials may not be the most cost-effective or acceptable to patients in everyday clinical practice.

Objectives

1. Explore patient, clinician and stakeholder views, experiences and preferences of alendronate compared to alternative bisphosphonates. 2. Update and refine the 2016 systematic review and cost-effectiveness analysis of bisphosphonates, and estimate the value of further research into their benefits. 3. Undertake stakeholder/consensus engagement to identify important research questions and further rank research priorities.

Methods

The study was conducted in two stages, stages 1A and 1B in parallel, followed by stage 2: • Stage 1A - we elicited patient and healthcare experiences to understand their preferences of bisphosphonates for the treatment of osteoporosis. This was undertaken by performing a systematic review and framework synthesis of qualitative studies, followed by semistructured qualitative interviews with participants. • Stage 1B - we updated and expanded the existing Health Technology Assessment systematic review and clinical and cost-effectiveness model, incorporating a more comprehensive review of treatment efficacy, safety, side effects, compliance and long-term persistence. • Stage 2 - we identified and ranked further research questions that need to be answered about the effectiveness and acceptability of bisphosphonates.

Results

Patients and healthcare professionals identified a number of challenges in adhering to bisphosphonate medication, balancing the potential for long-term risk reduction against the work involved in adhering to oral alendronate. Intravenous zoledronate treatment was generally more acceptable, with such regimens perceived to be more straightforward to engage in, although a portion of patients taking alendronate were satisfied with their current treatment. Intravenous zoledronate was found to be the most effective, with higher adherence rates compared to the other bisphosphonates, for reducing the risk of fragility fracture. However, oral bisphosphonates are more cost-effective than intravenous zoledronate due to the high cost of zoledronate administration in hospital. The importance of including patients and healthcare professionals when setting research priorities is recognised. Important areas for research were related to patient factors influencing treatment selection and effectiveness, how to optimise long-term care and the cost-effectiveness of delivering zoledronate in an alternative, non-hospital setting.

Conclusions

Intravenous zoledronate treatment was generally more acceptable to patients and found to be the most effective bisphosphonate and with greater adherence; however, the cost-effectiveness relative to oral alendronate is limited by its higher zoledronate hospital administration costs.

Future work

Further research is needed to support people to make decisions influencing treatment selection, effectiveness and optimal long-term care, together with the clinical and cost-effectiveness of intravenous zoledronate administered in a non-hospital (community) setting.

Limitations

Lack of clarity and limitations in the many studies included in the systematic review may have under-interpreted some of the findings relating to effects of bisphosphonates.

Risk factors for cervical instability in rheumatoid arthritis: a meta-analysis

Introduction

The aim of the study was to evaluate the risk factors for cervical instability in rheumatoid arthritis (RA).

Material and methods

Computer searches were conducted in PubMed, Embase, Cochrane Library, the China National Knowledge Infrastructure (CNKI) database, the Wan Fang database, the Chinese Scientific Journal Databases (VIP) database, and the Chinese Biomedical Literature database (CBM) from their establishment until November 2022.

Results

A total of 8 articles were included in this study, including 1 cross-sectional study, 5 case-control studies, and 2 cohort study, including 3078 patients with RA. Meta-analysis results showed that: male sex (OR = 1.70, 95% CI: 1.19-2.42), course of disease (OR = 1.72, 95% CI: 1.29-2.28), long-term glucocorticosteroid use (OR = 2.84, 95% CI: 1.97-2.40), Steinbrocker staging (OR = 2.30, 95% CI: 1.61-3.28), disability at baseline (OR = 24.57, 95% CI: 5.51-109.60), peripheral joint destruction (OR = 2.24, 95% CI: 1.56-3.21), Steinbrocker stage I-IV progression to disability (OR = 20.08, 95% CI: 4.18-96.53), and previous joint surgery (OR = 1.54, 95% CI: 1.06-2.26) are the main risk factors for cervical instability in RA.

Conclusions

There are many risk factors for cervical instability in RA. In clinical practice, special attention should be paid to patients who are male, have a longer course of disease, have long-term glucocorticosteroid use, have previous joint surgery, have peripheral joint damage, and develop disability in Steinbrocker stage I-IV. Attention should be paid to the high-risk groups mentioned above, and effective measures such as early screening and full monitoring should be taken to prevent the occurrence of cervical instability in RA.

Multidisciplinary Development and Initial Validation of a Clinical Knowledge Base on Chronic Respiratory Diseases for mHealth Decision Support Systems

Most mobile health (mHealth) decision support systems currently available for chronic obstructive respiratory diseases (CORDs) are not supported by clinical evidence or lack clinical validation. The development of the knowledge base that will feed the clinical decision support system is a crucial step that involves the collection and systematization of clinical knowledge from relevant scientific sources and its representation in a human-understandable and computer-interpretable way. This work describes the development and initial validation of a clinical knowledge base that can be integrated into mHealth decision support systems developed for patients with CORDs. A multidisciplinary team of health care professionals with clinical experience in respiratory diseases, together with data science and IT professionals, defined a new framework that can be used in other evidence-based systems. The knowledge base development began with a thorough review of the relevant scientific sources (eg, disease guidelines) to identify the recommendations to be implemented in the decision support system based on a consensus process. Recommendations were selected according to predefined inclusion criteria: (1) applicable to individuals with CORDs or to prevent CORDs, (2) directed toward patient self-management, (3) targeting adults, and (4) within the scope of the knowledge domains and subdomains defined. Then, the selected recommendations were prioritized according to (1) a harmonized level of evidence (reconciled from different sources); (2) the scope of the source document (international was preferred); (3) the entity that issued the source document; (4) the operability of the recommendation; and (5) health care professionals' perceptions of the relevance, potential impact, and reach of the recommendation. A total of 358 recommendations were selected. Next, the variables required to trigger those recommendations were defined (n=116) and operationalized into logical rules using Boolean logical operators (n=405). Finally, the knowledge base was implemented in an intelligent individualized coaching component and pretested with an asthma use case. Initial validation of the knowledge base was conducted internally using data from a population-based observational study of individuals with or without asthma or rhinitis. External validation of the appropriateness of the recommendations with the highest priority level was conducted independently by 4 physicians. In addition, a strategy for knowledge base updates, including an easy-to-use rules editor, was defined. Using this process, based on consensus and iterative improvement, we developed and conducted preliminary validation of a clinical knowledge base for CORDs that translates disease guidelines into personalized patient recommendations. The knowledge base can be used as part of mHealth decision support systems. This process could be replicated in other clinical areas.

2022 American College of Rheumatology Guideline for the Prevention and Treatment of Glucocorticoid-Induced Osteoporosis

OBJECTIVE

The objective is to update recommendations for prevention and treatment of glucocorticoid-induced osteoporosis (GIOP) for patients with rheumatic or nonrheumatic conditions receiving >3 months treatment with glucocorticoids (GCs) ≥2.5 mg daily.

METHODS

An updated systematic literature review was performed for clinical questions on nonpharmacologic, pharmacologic treatments, discontinuation of medications, and sequential therapy. Grading of Recommendations Assessment, Development and Evaluation approach was used to rate the certainty of evidence. A Voting Panel achieved ≥70% consensus on the direction (for or against) and strength (strong or conditional) of recommendations.

RESULTS

For adults beginning or continuing >3 months of GC treatment, we strongly recommend as soon as possible after initiation of GCs, initial assessment of fracture risks with clinical fracture assessment, bone mineral density with vertebral fracture assessment or spinal x-ray, and Fracture Risk Assessment Tool if ≥40 years old. For adults at medium, high, or very high fracture risk, we strongly recommend pharmacologic treatment. Choice of oral or intravenous bisphosphonates, denosumab, or parathyroid hormone analogs should be made by shared decision-making. Anabolic agents are conditionally recommended as initial therapy for those with high and very high fracture risk. Recommendations are made for special populations, including children, people with organ transplants, people who may become pregnant, and people receiving very high-dose GC treatment. New recommendations for both discontinuation of osteoporosis therapy and sequential therapies are included.

CONCLUSION

This guideline provides direction for clinicians and patients making treatment decisions for management of GIOP. These recommendations should not be used to limit or deny access to therapies.

Research priorities regarding the use of bisphosphonates for osteoporosis: a UK priority setting exercise

PURPOSE

Worldwide, many people who would benefit from osteoporosis drugs are not offered or receiving them, resulting in an osteoporosis care gap. Adherence with bisphosphonates is particularly low. This study aimed to identify stakeholder research priorities relating to bisphosphonate treatment regimens for prevention of osteoporotic fractures.

METHODS

A three-step approach based on the James Lind Alliance methodology for identification and prioritisation of research questions was used. Research uncertainties were gathered from a large programme of related research studies about bisphosphonate regimens and from recent published international clinical guidelines. Clinical and public stakeholders refined the list of uncertainties into research questions. The third step prioritised the questions using a modified nominal group technique.

RESULTS

In total, 34 draft uncertainties were finalised into 33 research questions by stakeholders. The top 10 includes questions relating to which people should be offered intravenous bisphosphonates first line (1); optimal duration of treatment (2); the role of bone turnover markers in treatment breaks (3); support patient need for medicine optimisation (4); support primary care practitioner need regarding bisphosphonates (5); comparing zoledronate given in community vs hospital settings (6); ensuring quality standards are met (7); the long-term model of care (8); best bisphosphonate for people aged under 50 (9); and supporting patient decision-making about bisphosphonates (10).

CONCLUSION

This study reports, for the first time, topics of importance to stakeholders in the research of bisphosphonate osteoporosis treatment regimens. These findings have implications for research into implementation to address the care gap and education of healthcare professionals. Using James Lind Alliance methodology, this study reports prioritised topics of importance to stakeholders in the research of bisphosphonate treatment in osteoporosis. The priorities address how to better implement guidelines to address the care gap, understanding patient factors influencing treatment selection and effectiveness, and how to optimise long-term care.

Time Trends in Glucocorticoid Use in Rheumatoid Arthritis During the Biologics Era: 1999-2018

OBJECTIVES

To examine time trends in glucocorticoid (GC) use among patients diagnosed with rheumatoid arthritis (RA) during the biologic era.

METHODS

A population-based inception cohort of RA patients diagnosed during 1999 - 2018 was followed longitudinally through their medical records until death, migration or 12/31/2020. All patients fulfilled 1987 American College of Rheumatology classification criteria for RA. GC start and stop dates were collected along with dosages in prednisone equivalents. The cumulative incidence of GC initiation and discontinuation adjusted for the competing risk of death was estimated. Cox models adjusted for age and sex were used to compare trends between time periods.

RESULTS

The study population included 399 patients (71% female) diagnosed in 1999 - 2008 and 430 patients (67% female) diagnosed in 2009 - 2018. GC use was initiated within 6 months of meeting RA criteria in 67% of patients in 1999-2008 and 71% of patients in 2009-2018, corresponding to a 29% increase in hazard for initiation of GC in 2009-2018 (adjusted hazard ratio [HR]: 1.29; 95% confidence interval [CI]: 1.09-1.53). Among GC users, similar rates of GC discontinuation within 6 months after GC initiation were observed in patients with RA incidence in 1999 - 2008 and 2009 - 2018 (39.1% versus 42.9%, respectively), with no significant association in adjusted Cox models (HR: 1.11; 95% CI: 0.93-1.31).

CONCLUSION

More patients are initiating GCs early in their disease course now compared to previously. The rates of GC discontinuation were similar, despite the availability of biologics.

Management of Adrenal Cortical Adenomas: Assessment of Bone Status in Patients with (Non-Functioning) Adrenal Incidentalomas

Our aim is to analyse the bone profile in adults with (non-functioning) adrenal incidentalomas (AIs), specifically addressing the impact of autonomous cortisol secretion (ACS). This narrative review, based on a PubMed search from inception to February 2023 (case reports, non-ACS, and other secondary causes of osteoporosis were excluded), included 40 original studies, a total of 3046 patients with female prevalence (female:male ratio of 1921:1125), aged between 20.5 and 95.5 years old. This three decade-based analysis showed that 37 studies provided dual-energy X-ray absorptiometry (DXA) information; another five studies reports results on bone micro-architecture, including trabecular bone score (TBS), spinal deformity index, and high-resolution peripheral quantitative computed tomography; 20 cohorts included data on bone turnover markers (BTMs), while four longitudinal studies followed subjects between 1 and 10.5 years old (surgical versus non-adrenalectomy arms). Post-dexamethasone suppression test (DST) cortisol was inversely associated with bone mineral density (BMD). TBS predicted incidental vertebral fractures (VFx) regardless of BMD, being associated with post-DST cortisol independently of age and BMD. Low BTMs were identified in ACS, but not all studies agreed. An increased prevalence of ACS-related osteoporosis was confirmed in most studies (highest prevalence of 87.5%), as well as of VFx, including in pre-menopause (42.5%), post-menopause (78.6%), and male patients (72.7%) depending on the study, with a 10-fold increased incidental VFx risk up to a 12-fold increased risk after a 2-year follow-up. No specific medication against osteoporosis is indicated in ACS, but adrenalectomy (according to four studies) should be part of the long-term strategy. This bone profile case sample-based study (to our knowledge, one of the largest of its kind) showed that AIs, including the subgroup designated as having ACS, embraces a large panel of osseous complications. The level of evidence remains far from generous; there are still no homogenous results defining ACS and identifying skeletal involvement, which might be a consequence of different investigation clusters underling adrenal and bone assessments over time. However, bone status evaluations and associated therapy decisions remain an essential element of the management of adults with AIs-ACS.

Threshold based on bone mineral density for therapeutic decision-making in postmenopausal women and men over 50 years old under glucocorticoid therapy

INTRODUCTION AND AIM

T-score bone mineral density (BMD) thresholds may influence guidance for treatment in patients under glucocorticoid (GC) therapy. Different BMD thresholds have been described but there is no international consensus. The aim of this study was to find a threshold to help in treatment decision-making in the population under GC therapy.

METHODS

A working group representing three scientific societies from Argentina was convened. The first team was formed by specialists with expertise in glucocorticoid-induced osteoporosis (GIO) who voted according to summary of evidence. The second team was constituted by a methodology group who coordinated and supervised each stage. We conducted two systematic reviews to synthesize the evidence. The first included trials of drugs used in GIO to analyze the BMD cut-off used as inclusion criteria. In the second, we analyzed the evidence regarding the densitometric thresholds to discriminate between fractured and non-fractured patients under GC treatment.

RESULTS

In the first review, 31 articles were included for qualitative synthesis and more than 90% of the trials included patients regardless of their densitometric T-score or range of osteopenia. In the second review, 4 articles were included and more than 80% of the T-scores were in the range -1.6 to -2.0. The summary of findings was analyzed and put to a vote.

CONCLUSIONS

With more than 80% agreement of the voting expert panel, a T-score≤-1.7 was considered the most appropriate for treatment in postmenopausal women and men over 50 years of age under GC therapy. This study could help in treatment decision-making in patients under GC therapy without fractures but other fracture risk factors should certainly be considered.

Vitamin D-induced hypercalcaemia and acute kidney injury in sarcoidosis

Vitamin D deficiency is relatively common, and its management in patients with sarcoidosis is challenging due to the risk of hypercalcaemia. Our patient had an autologous stem cell transplant for multiple sclerosis and was given high-dose vitamin D concurrently with immunosuppressive therapy. The patient subsequently presented with symptomatic hypercalcaemia and an acute kidney injury. A clinical and biochemical recovery was reached by withdrawing vitamin D and administering intravenous fluids. Interestingly, new evidence suggests that activated vitamin D can actually dampen the inflammatory process in sarcoidosis, and this was reflected in a reduction of our patient's serological markers of sarcoidosis activity. One large study found no significant risk of hypercalcaemia when low doses of vitamin D were used in sarcoidosis. Where indicated, and until clear guidelines are established, we suggest using low doses of vitamin D with cautious monitoring of calcium and renal function.

A Critical Look at Race-Based Practices in Rheumatology Guidelines

OBJECTIVE

To assess how race has been incorporated into rheumatology practice guidelines, including how race is defined and used in diagnostic and treatment recommendations.

METHODS

We searched race and ethnicity terms in all clinical practice guidelines from the American College of Rheumatology (ACR) and European Alliance of Associations for Rheumatology (EULAR) that were published between 2010 and 2020 and publicly available on professional society websites. Findings were summarized and assessed through standardized data abstraction forms. Key themes were identified through a thematic analysis approach.

RESULTS

A total of 23 ACR clinical practice guidelines and 42 EULAR recommendations were reviewed. In total, 16 of 65 (25%) of the guidelines used race terms in their text. No guideline clearly defined race, and race was often conflated with ethnicity and/or genetic ancestry. Reported racial categories varied substantially by guideline and often used classifications that oversimplified and excluded non-White races. Research with insufficient racial diversity was used to make race-based recommendations for Black patients that may not be generalizable. Additionally, recommendations using research on predominantly White populations reinforced data of White populations as normative and perpetuated race-based stereotypes, especially for rare diseases. Structural causes of identified racial disparities were not discussed in clinical guidelines.

CONCLUSION

There is an urgent need for standardized race reporting in rheumatology. Recommendations are provided to enhance consistency and accuracy of race and ethnicity terms, mitigate conflation of race with ethnicity or genetic ancestry, encourage a critical reanalysis of race-based diagnostic tools and treatment options, and better address the structural causes of racial disparities.

Consensus statements for pharmacological management, monitoring of therapies, and comorbidity management of psoriatic arthritis in the United Arab Emirates

OBJECTIVE

Psoriatic arthritis (PsA), a chronic inflammatory disease characterized by heterogeneous clinical manifestations, substantially impacts the quality of life of affected individuals. This article aims at developing consensus recommendations for the management of PsA and associated comorbidities and screening and monitoring requirements of PsA therapies in the United Arab Emirates (UAE) population.

METHODS

An extensive review of present international and regional guidelines and publications on the pharmacological management, monitoring of therapies in the context of PsA was performed. Key findings from guidelines and literature were reviewed by a panel of experts from the UAE at several meetings to align with current clinical practices. Consensus statements were formulated based on collective agreement of the experts and members of Emirates Society for Rheumatology.

RESULTS

The consensus recommendations were developed to aid practitioners in clinical decision-making with respect to dosage recommendations for pharmacological therapies for PsA, including conventional drugs, non-biologic, and biologic therapies. Consensus recommendations for therapeutic options for the treatment of PsA domains, including peripheral arthritis, axial disease, enthesitis, dactylitis, psoriasis, and nail disease, were developed. The panel emphasized the importance of monitoring PsA therapies and arrived at a consensus on monitoring requirements for PsA therapies. The expert panel proposed recommendations for the management of common comorbidities associated with PsA.

CONCLUSION

These consensus recommendations can guide physicians and healthcare professionals in the UAE in making proper treatment decisions, as well as efficiently managing comorbidities and monitoring therapies in patients with PsA.

Sarcoidosis in the older person: diagnostic challenges and treatment consideration

BACKGROUND

Sarcoidosis is a multi-system disorder with an increasing propensity to present in older patients. Diagnostic uncertainty is common and understandable given the higher prevalence of co-morbidities in older patients and broad differential for multi-system clinical presentations. Excluding malignancy and infection with a high degree of certainty is challenging and may require repeated confirmatory investigation where the diagnosis remains in doubt.

SUMMARY OF MAIN FINDINGS

There are a paucity of studies examining late-onset sarcoidosis. Female predominance, pulmonary, ocular, skin and systemic symptoms are common, while more classical presentations such as Lofgren's syndrome are uncommon. Positivity rates of biopsies vary between studies; however, targeted biopsies of accessible sites with organ involvement are the most successful. Therapeutic management is directed at reducing inflammation, and thereby reducing symptom burden, improving quality of life and avoiding progression of organ damage. While most older patients will require corticosteroid therapy, they are also more prone to developing adverse effects. Most older patients will experience a clinical remission; however, the risk of developing chronic sarcoidosis and organ damage is higher compared with younger counterparts. Patients with evidence of pulmonary fibrosis and pulmonary hypertension are at particular risk.

IMPACT ON CLINICAL PRACTICE

Health care providers who care for older adults should be aware of the increasing prevalence of late-onset sarcoidosis and consider the diagnosis in those who present with otherwise unexplained systemic symptoms, thoracic abnormalities on imaging and/or evidence of other organ involvement. Earlier diagnosis and therapeutic intervention to halt the development of pulmonary fibrosis and pulmonary hypertension and monitoring for treatment-related adverse effects will confer a mortality benefit.

Updated S2 K guidelines for the management of bullous pemphigoid initiated by the European Academy of Dermatology and Venereology (EADV)

BACKGROUND

Bullous pemphigoid (BP) is the most common autoimmune subepidermal blistering disease of the skin and mucous membranes. This disease typically affects the elderly and presents with itch and localized or, most frequently, generalized bullous lesions. A subset of patients only develops excoriations, prurigo-like lesions, and eczematous and/or urticarial erythematous lesions. The disease, which is significantly associated with neurological disorders, has high morbidity and severely impacts the quality of life.

OBJECTIVES AND METHODOLOGY

The Autoimmune blistering diseases Task Force of the European Academy of Dermatology and Venereology sought to update the guidelines for the management of BP based on new clinical information, and new evidence on diagnostic tools and interventions. The recommendations are either evidence-based or rely on expert opinion. The degree of consent among all task force members was included.

RESULTS

Treatment depends on the severity of BP and patients' comorbidities. High-potency topical corticosteroids are recommended as the mainstay of treatment whenever possible. Oral prednisone at a dose of 0.5 mg/kg/day is a recommended alternative. In case of contraindications or resistance to corticosteroids, immunosuppressive therapies, such as methotrexate, azathioprine, mycophenolate mofetil or mycophenolate acid, may be recommended. The use of doxycycline and dapsone is controversial. They may be recommended, in particular, in patients with contraindications to oral corticosteroids. B-cell-depleting therapy and intravenous immunoglobulins may be considered in treatment-resistant cases. Omalizumab and dupilumab have recently shown promising results. The final version of the guideline was consented to by several patient organizations.

CONCLUSIONS

The guidelines for the management of BP were updated. They summarize evidence- and expert-based recommendations useful in clinical practice.

A prediction study of IL-18 and IFN-γ in glucocorticoid treatment response in infants and young children with severe Mycoplasma pneumoniae pneumonia

BACKGROUND

In infants and young children, the clinical decision to apply glucocorticoids to severe Mycoplasma pneumoniae pneumonia (SMPP) is more an empirical choice with reference to clinical symptoms, but the effect is not satisfying. We aimed to explore and identify early predictive indicators of ideal response to glucocorticoids treatment in SMPP in infants and young children.

METHODS

We retrospectively reviewed the data of 59 patients, which met the age range and diagnostic criteria, admitted to Department of Pediatrics, the Sixth People's Hospital Affiliated to Shanghai Jiaotong University, from January to December 2017. Patients were divided into a glucocorticoid treatment group and a normal treatment group according to whether glucocorticoid treatment was used, and the difference in therapeutic effectiveness was compared between two groups. The glucocorticoid treatment group was further subdivided into effective versus ineffective treatment groups dependent on the difference of glucocorticoid treatment effect in main clinical symptoms improvement. We obtained the test value of biomarkers by ELISA, and identified several specific indicators with significantly different expressions in the early stage by independent sample t-tests and calculated their cut-off values by ROC curve.

RESULTS

Thirty-one SMPP patients who received glucocorticoid treatment were divided into effective and ineffective treatment groups according to the clinical improvements shown on different days of glucocorticoid use. The expression of two markers, interleukin-18 (IL-18) and interferon-γ (IFN-γ), were significantly different in cases showing improvement in the early stage of SMPP (P<0.05), and the cut-off values for IL-18 (218.19 pg/mL, AUC =0.581, sensitivity =0.909, 1-specificity =0.786) and IFN-γ (11.24 pg/mL, AUC =0.566, sensitivity =0.905, 1-specificity =0.795) were identified.

CONCLUSIONS

The expressions of IL-18 and IFN-γ in the early stage of SMPP might suggest their predictive effect of early application of glucocorticoid for effective treatment of SMPP in infants and young children. Further study with larger sample size will be carried on in the future.

Omalizumab: An Optimal Choice for Patients with Severe Allergic Asthma

Omalizumab is the first monoclonal antibody that was globally approved as a personalized treatment option for patients with moderate-to-severe allergic asthma. This review summarizes the knowledge of almost two decades of use of omalizumab to answer some important everyday clinical practice questions, concerning its efficacy and safety and its association with other asthma-related and drug-related parameters. Evidence suggests that omalizumab improves asthma control and reduces the incidence and frequency of exacerbations in patients with severe allergic asthma. Omalizumab is also effective in those patients in reducing corticosteroid use and healthcare utilization, while it also seems to improve lung function. Several biomarkers have been recognized in predicting its efficacy in its target group of patients, while the optimal duration for evaluating its efficacy is between 16 and 32 weeks.

A bibliometric and visualization analysis of glucocorticoid-induced osteoporosis research from 2012 to 2021

INTRODUCTION

Glucocorticoid-induced osteoporosis (GIOP) is the most common cause of secondary osteoporosis. Although many studies related to GIOP have been published, there was no bibliometric analysis in this field. This study aimed to investigate the research trends on GIOP by using bibliometric analysis.

MATERIALS AND METHODS

All data were collected from the Web of Science Core Collection (WoSCC). All original research articles regarding GIOP from 2012 to 2021 were retrieved. CiteSpace was used to analyze the distribution of countries, institutions, journals, authors, and keywords. We revealed hotspots and trends in the field by drawing co-occurrence keyword maps and identifying burst keywords.

RESULTS

From 2012 to 2021, 685 relevant articles were published, with a peak in 2018 in the annual number of publications. China and McMaster University were the leading country and institution in this field with 208 and 12 publications, respectively. Osteoporosis International was the journal with the most studies, while Journal of Bone and Mineral Research was the most cited journal. "Bone mineral density", "fracture", "postmenopausal women", "prevention" and "therapy" were the most high-frequency keywords, while "bone mineral density", "bisphosphonate" and "metabolism" were the top high-centrality keywords.

CONCLUSION

The results from this bibliometric study provided insight into the status and research trends in GIOP of the past decade, which could help researchers quickly determine the current hotspots and frontier trends in this field.

Rheumatoid Arthritis is a Risk Factor for Refracture in Patients with Fragility Fractures

OBJECTIVES

To determine whether patients with rheumatoid arthritis (RA) who have had fragility fractures are at an increased risk of refractures.

METHODS

Patients with fragility fractures who were treated surgically at ten hospitals from 2008 to 2017 and who underwent follow-up for more than 24 months were either categorized into a group comprising patients with RA or a group comprising patients without RA (controls). The groups were matched 1:1 by propensity score matching. Accordingly, 240 matched participants were included in this study. The primary outcome was the refracture rate in patients with RA as compared to in the controls. Multivariable analyses were also conducted on patients with RA to evaluate the odds ratios (ORs) for the refracture rates.

RESULTS

Patients with RA were significantly associated with increased rates of refractures during the first 24 months (OR: 2.714, 95% confidence interval [95% CI]: 1.015-7.255; P = 0.040). Multivariable analyses revealed a significant association between increased refracture rates and long-term RA (OR: 6.308, 95% CI: 1.195-33.292; P=0.030).

CONCLUSIONS

Patients with RA who have experienced fragility fractures are at an increased risk of refractures. Long-term RA is a substantial risk factor for refractures.

Epidemiology of glucocorticoid-induced osteoporosis and management of associated fracture risk in Japan

INTRODUCTION

Glucocorticoid-induced osteoporosis (GIOP) is associated with a high fracture risk. Practice guidelines by the Japanese Society for Bone and Mineral Research in 2014 recommend bone densitometry and appropriate treatment to reduce this risk. The study objectives were to describe characteristics of GIOP patients in Japan and to evaluate their management in a subgroup of patients without comorbid cancer.

MATERIALS AND METHODS

This retrospective cohort study was performed using the Medical Data Vision (MDV) database from Japan. Adult patients initiating oral glucocorticoid treatment with a total GIOP risk score ≥ 3, based on the 2014 practice guideline, identified between 2009 and 2019 were eligible. A subgroup of patients without any cancer diagnosis was also identified. Data were extracted on demographics, concurrent medical conditions, use of bone densitometry, and osteoporosis treatment.

RESULTS

25,569 patients were eligible, of whom 12,227 had a confirmed cancer diagnosis. Mean age was 68.5 years and 12,356 patients (48.3%) were women. Concurrent medical conditions of interest were documented in 14,887 patients, most frequently rheumatoid arthritis (n = 4185) and asthma (n = 3085). Yearly bone densitometry was performed in 6.5% (n = 865) of the cancer-free subgroup; 51.8% (n = 6905) were prescribed an osteoporosis treatment, most frequently bisphosphonates (n = 5132; 74.3%). Between 2011 and 2018, rates of densitometry were stable, whereas prescription rates increased from 40.0 to 51.8%.

CONCLUSION

In spite of publication of guidelines for GIOP management, there is an important treatment gap in their application in everyday practice. For this reason, public health measures to increase physician awareness of GIOP are needed.

Vitamin D Supplementation in Sarcoidosis: A Double-Edged Sword

Sarcoidosis is complicated by disordered vitamin D and calcium metabolism, which has important implications on disease activity and bone health. Although the majority of the patients with sarcoidosis are typically deficient in 25-hydroxyvitamin D, repletion of vitamin D is controversial in light of the hypercalcemia risk. Presently, there are no clear guidelines regarding vitamin D supplementation as a part of osteoporosis prevention in patients with vitamin D deficiency and sarcoidosis. We report a patient with sarcoidosis who presented with severe hypercalcemia following vitamin D supplementation and review the debated role of vitamin D supplementation in vitamin D-deficient sarcoid patients.

Vitamin D and Lupus: Are we doing enough?

The aim of this study is to identify rheumatology practice care gaps in evaluating for vitamin D deficiency in systemic lupus erythematosus (SLE), as well as adherence to vitamin D replacement in SLE patients currently on corticosteroid therapy. Data for this study were collected from the Southern California Lupus Registry in addition to data extraction from medical health records. Evaluation of serum vitamin D level within 6 months of patient encounter, current or prior use of systemic corticosteroids, and vitamin D replacement in patients receiving corticosteroid therapy were noted. Vitamin D deficiency was defined as serum 25(OH)D₃ less than 30 ng/ml. Of 182 patients in the cohort, data were available for 176. Evaluation of vitamin D deficiency was noted in 49 patients (28%), 27 (55%) of whom had abnormal values. Current corticosteroid use was noted in 56 (32%) patients and prior use in 73 (41%). Vitamin D replacement was prescribed to 30 (54%) patients with current corticosteroid use. In an academic rheumatology clinic, we have identified underevaluation for vitamin D deficiency in SLE patients despite increasing awareness of its contribution to disease activity. Further, routine supplementation of vitamin D is particularly lacking in individuals receiving systemic corticosteroids. This presents a practical opportunity for improvement in SLE clinical care.

Fracture risk in systemic lupus erythematosus patients over 28 years

OBJECTIVES

Chronic glucocorticoid use is complicated by osteoporosis and increases the risk of fragility fractures. EULAR guidelines on SLE management recommend reducing chronic glucocorticoid dosage to ≤7.5 mg/day to minimize this risk. We examined the relationship of glucocorticoid dose to fragility fracture risk in a cohort of SLE patients.

METHODS

Retrospective analysis of SLE patients attending University College Hospital over 28 years was undertaken. Collected data included consecutive steroid dose, dual-energy X-ray absorptiometry scans and fragility fractures.

RESULTS

We collected data on 250 patients with a median of 17 years' follow-up. Fragility fractures were diagnosed in 28 (11.2%) patients and the mean ± s.d. age of first fracture was 51 ± 16 years. A total of 94% received glucocorticoids, the average dose being 6.20 mg/day. Patients with fragility fractures had a lower average daily dose (5.36 vs 6.23 mg/day) but a higher median cumulative dose (25.19 vs 20.96 g). These differences were not significant (P = 0.127 and 0.229, respectively). Some 93% of patients received vitamin D, and 85% received calcium. Cox regression analysis showed older age at SLE diagnosis, osteoporosis and secondary hyperparathyroidism were associated with fragility fractures. Glucocorticoid dose was not significantly associated with the occurrence of fragility fractures. Twenty-two patients with fractures were treated with bisphosphonates, two with denosumab and two with teriparatide.

CONCLUSIONS

We found no significant association between glucocorticoid treatment and fragility fractures in our group of patients; however, a prospective study including more patients not treated with CS would be necessary to confirm these results.

[Osteoporosis in pneumological diseases : Joint guideline of the Austrian Society for Bone and Mineral Research (ÖGKM) and the Austrian Society for Pneumology (ÖGP)]

Chronic inflammation induces proinflammatory cytokine cascades. In addition to systemic inflammation, hypoxemia, hypercapnia, a catabolic metabolism, gonadal or thyroid dysfunction, musculoskeletal dysfunction and inactivity as well as vitamin D deficiency contribute to an increased risk of fragility fractures. Iatrogenic causes of osteoporosis are long-term use of inhaled or systemic glucocorticoids (GC). Inhalative GC application in asthma is often indicated in childhood and adolescence, but interstitial lung diseases such as chronic organizing pneumonia, COPD, sarcoid or rheumatic diseases with lung involvement are also treated with inhalative or oral GC. In patients with cystic fibrosis, malabsorption in the context of pancreatic insufficiency, hypogonadism and chronic inflammation with increased bone resorption lead to a decrease in bone structure. After lung transplantation, immunosuppression with GC is a risk factor.The underlying pneumological diseases lead to a change in the trabecular and cortical bone microarchitecture and to a reduction in osteological formation and resorption markers. Hypercapnia, acidosis and vitamin D deficiency can accelerate this process and thus increase the individual risk of osteoporotic fragility fractures.A bone mineral density measurement with a T‑Score < -2.5 is a threshold value for the diagnosis of osteoporosis; in contrast the vast majority of all osteoporotic fractures occur with a T‑Score > -2.5. A history of low-trauma fracture indicates osteological therapy.All antiresorptive or anabolic drugs approved in Austria for the treatment of osteoporosis are also indicated for pneumological patients with an increased fragility fracture risk of bone fractures in accordance with the national reimbursement criteria.

Guidelines for the prevention and treatment of glucocorticoid-induced osteoporosis: an update of Brazilian Society of Rheumatology (2020)

The Brazilian guidelines for prevention and treatment of glucocorticoid-induced osteoporosis were updated and important topics were included such as assessment of risk fracture using FRAX Brazil, use of denosumab, and also recommendations for the use of glucocorticoid pulse therapy and inhaled glucocortiocoid.

INTRODUCTION

Glucocorticoids (GCs) are used in almost all medical specialties and the incidences of vertebral/nonvertebral fractures range from 30 to 50% in individuals treated with GCs for over 3 months. Thus, osteoporosis and frailty fractures should be prevented and treated in patients initiating treatment or already being treated with GCs. The Committee for Osteoporosis and Bone Metabolic Disorders of the Brazilian Society of Rheumatology (BSR) established in 2012 the Brazilian Guidelines for glucocorticoid-induced osteoporosis (GIO). Herein, we provide a comprehensive update of the original guidelines based on improved available scientific evidence and/or expert experience.

METHODS

From March to June 2020, the Osteoporosis Committee of the BRS had meetings to update the questions presented in the first consensus (2012). Thus, twenty-six questions considered essential for the preparation of the recommendations were selected. A systematic literature review based on real-life scenarios was undertaken to answer the proposed questions. The MEDLINE, EMBASE, and SCOPUS databases were searched using specific search keywords.

RESULTS

Based on the review and expert opinion, the recommendations were updated for each of the 26 questions. We included 48 new bibliographic references that became available after the date of the publication of the first version of the consensus.

CONCLUSION

We updated the Brazilian guidelines for the prevention/treatment of GIO. New topics were added in this update, such as the assessment of risk fracture using FRAX Brazil, the use of denosumab, and approaches for the treatment of children and adolescents. Furthermore, we included recommendations for the use of inhaled GCs and GC pulse therapy in clinical settings.

Fracture Risk in Patients with Myasthenia Gravis: A Population-Based Cohort Study

BACKGROUND

Prednisone is a common treatment for myasthenia gravis (MG), and osteoporosis is a known potential risk of chronic prednisone therapy.

OBJECTIVE

Our aim was to evaluate the risk of serious fractures in a population-based cohort of MG patients.

METHODS

An inception cohort of patients with MG was identified from administrative health data in Ontario, Canada between April 1, 2002 and December 31, 2015. For each MG patient, we matched 4 general population comparators based on age, sex, and region of residence. Fractures were identified through emergency department and hospitalization data. Crude overall rates and sex-specific rates of fractures were calculated for the MG and comparator groups, as well as rates of specific fractures. Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox regression.

RESULTS

Among 3,823 incident MG patients (followed for a mean of 5 years), 188 (4.9%) experienced a fracture compared with 741 (4.8%) fractures amongst 15,292 matched comparators. Crude fracture rates were not different between the MG cohort and matched comparators (8.71 vs. 7.98 per 1000 patient years), overall and in men and women separately. After controlling for multiple covariates, MG patients had a significantly lower risk of fracture than comparators (HR 0.74, 95% CI 0.63-0.88).

CONCLUSIONS

In this large, population-based cohort of incident MG patients, MG patients were at lower risk of a major fracture than comparators. The reasons for this finding are unclear but may highlight the importance osteoporosis prevention.

Treatment of multiple myeloma-related bone disease: recommendations from the Bone Working Group of the International Myeloma Working Group

In this Policy Review, the Bone Working Group of the International Myeloma Working Group updates its clinical practice recommendations for the management of multiple myeloma-related bone disease. After assessing the available literature and grading recommendations using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) method, experts from the working group recommend zoledronic acid as the preferred bone-targeted agent for patients with newly diagnosed multiple myeloma, with or without multiple myeloma-related bone disease. Once patients achieve a very good partial response or better, after receiving monthly zoledronic acid for at least 12 months, the treating physician can consider decreasing the frequency of or discontinuing zoledronic acid treatment. Denosumab can also be considered for the treatment of multiple myeloma-related bone disease, particularly in patients with renal impairment. Denosumab might prolong progression-free survival in patients with newly diagnosed multiple myeloma who have multiple myeloma-related bone disease and who are eligible for autologous stem-cell transplantation. Denosumab discontinuation is challenging due to the rebound effect. The Bone Working Group of the International Myeloma Working Group also found cement augmentation to be effective for painful vertebral compression fractures. Radiotherapy is recommended for uncontrolled pain, impeding or symptomatic spinal cord compression, or pathological fractures. Surgery should be used for the prevention and restoration of long-bone pathological fractures, vertebral column instability, and spinal cord compression with bone fragments within the spinal route.

Paraneoplastic neurological syndromes: clinical presentations and management

We provide an overview of the varied presentations of paraneoplastic neurological syndromes. We also review the onconeural antibodies and their particular oncological and neurological associations. Recognition of these syndromes and their oncological associations is crucial, as early diagnosis and management has been associated with better patient outcomes. Specific management strategies and prognosis vary widely depending on the underlying etiology. An understanding of the relevant clinical details, imaging findings, and other diagnostic information can help tailor treatment approaches. We provide an outline of the diagnostic evaluation and treatment of various paraneoplastic neurological disorders, presenting with central and/or peripheral nervous system involvement. We briefly discuss neurologic immune checkpoint inhibitor-related adverse events, which can occasionally present with paraneoplastic neurological syndrome phenotypes.

Intervention Thresholds for Treatment in Patients with Glucocorticoid-Induced Osteoporosis: Systematic Review of Guidelines

Background

In this study, we aimed to evaluate and compare the treatment indication for patients with glucocorticoid-induced osteoporosis (GIOP) in various clinical practice guidelines.

Methods

We searched for potentially relevant studies conducted from January 2000 to March 2020 using online databases, including PubMed, Ovid-EMBASE, Guidelines International Network, National Institute for Health and Clinical Excellence, KoreaMed, KMbase, and KoMGI. We reviewed and analyzed the guidelines that included recommendations on GIOP and fulfilled the inclusion criteria.

Results

A total of 94 articles were selected based on review of the title and abstract; 14 guidelines were assessed upon reviewing the full text. The bone mineral density score for therapeutic intervention of GIOP in postmenopausal women was presented in 7 guidelines, among which 3 guidelines set a T-score of −2.5 or lower and the other 4 guidelines proposed a less stringent cut-off point of −1.5 or lower. Among the 10 guidelines published since 2012 after the emergence of the fracture risk assessment tool (FRAX), 6 guidelines included FRAX in their criteria for defining intervention thresholds. However, they were further divided into fixed-probability (n=3) and age-dependent (n=3) thresholds based on the country.

Conclusions

Recently developed guidelines use FRAX as the criterion for establishing the treatment of patients with GIOP. However, these intervention thresholds need to be adapted for each country.

Effect of Teriparatide on Bone Remodeling and Density in Premenopausal Idiopathic Osteoporosis: A Phase II Trial

CONTEXT

Premenopausal women with idiopathic osteoporosis (IOP) have abnormal skeletal microarchitecture and variable tissue-level bone formation rate (BFR).

OBJECTIVES

Compare 6 months (M) of teriparatide versus placebo on areal bone mineral density (aBMD) by dual-energy x-ray absorptiometry (DXA), bone turnover markers (BTMs) and BFR at 3M by quadruple-labeled transiliac biopsy. Characterize 12M and 24M effects of teriparatide on aBMD and whether BTMs and BFR predict response.

DESIGN

6M phase 2 randomized controlled trial (RCT) followed by open extension.

SETTING

Tertiary referral centers.

PATIENTS

Premenopausal women with IOP.

INTERVENTIONS

A total of 41 women were randomized to either teriparatide 20 mcg (n = 28) or placebo (n = 13). After 6M, those on placebo switched to teriparatide for 24M; those on teriparatide continued for 18M.

MAIN OUTCOME MEASURES

6M RCT: Between-group differences in lumbar spine (LS) aBMD (percent change from baseline), 3M BFR, and hypercalcemia. Open-label extension: Within-group change in LS aBMD over 12M and 24M. Secondary outcomes included aBMD change at other sites and relationship between BTMs, BFR, and changes in aBMD.

FINDINGS

Over 6M, LS aBMD increased by 5.5% (95% CI: 3.83, 7.19) in teriparatide and 1.5% (95% CI: -0.73, 3.83) in placebo (P = 0.007). There were increases in 3M BTMs, and BFR (cancellous and endocortical BFR: between-groups P = 0.004). Over 24M, teriparatide increased LS aBMD by 13.2% (95% CI: 10.3, 16.2), total hip by 5.2% (95% CI: 3.7, 6.7) and femoral neck by 5.0% (95% CI: 3.2, 6.7; all P ≤ 0.001). Serum N-terminal propeptides of procollagen type 1 (P1NP) and 3M endocortical BFR were moderately associated with LS aBMD response. Teriparatide was well-tolerated.

CONCLUSIONS

Teriparatide increased BFR and formation markers and was associated with marked aBMD improvements in most premenopausal women (82%) with IOP.

Balancing Altered Calcium Metabolism with Bone Health in Sarcoidosis

Abnormal calcium metabolism in sarcoidosis patients can lead to hypercalcemia, hypercalciuria, and kidney stones. Hypercalcemia in sarcoidosis is usually due to increased activity of 1α-hydroxylase in macrophages of pulmonary granulomata, resulting in low levels of 25-hydroxyvitamin D and high levels of calcitriol. Vitamin D supplementation may be dangerous for some sarcoidosis patients and is recommended only for those with decreased 25-hydroxyvitamin D and reduced or normal calcitriol level. Diagnosis, treatment of osteoporosis, and maintenance of bone health are complex issues for sarcoidosis patients. An approach to diagnosis and treatment of bone fragility is presented.

Effects of glucocorticoids on osteoporosis in rheumatoid arthritis: a systematic review and meta-analysis

We evaluated the effects of glucocorticoids on bone mineral density (BMD), and prevalence of osteoporosis and fracture in rheumatoid arthritis (RA) by meta-analysis. Until June 26, 2019, we conducted a systematic literature search in EMBASE, Web of science, PubMed, and Cochrane Library to obtain BMD and the prevalence of osteoporosis and fracture in glucocorticoid-treated subjects with RA. The BMD of the treatment and control groups were analyzed by meta-analysis (Stata. version 15), and the 95% confidence interval (CI) was calculated. We identified 15 observational studies, including 46,711 RA subjects and 857 healthy controls. The BMD of the lumbar spine (- 0.038 g/cm²; CI, - 0.052, - 0.024) and femoral neck (- 0.017 g/cm²; - 0.030, - 0.003) in RA treated with glucocorticoids were significantly lower than those in RA controls. Compared with healthy control group, the BMD of the lumbar spine (- 0.094 g/cm²; - 0.126, - 0.061) and femoral neck (- 0.097 g/cm², - 0.109, - 0.085) of RA treated with glucocorticoids decreased more significantly. The prevalence of osteoporosis in whole body, spine, and femur was 38.6% (0.305, 0.466), 32.9% (0.277, 0.381), and 21.7% (0.106, 0.328), respectively. And the prevalence of vertebral fracture was 13.0% (0.058, 0.203). Glucocorticoids may lead to a decline in skeletal health in subjects with RA, especially in vertebral and femoral BMD, compared with normal people or RA without glucocorticoid therapy. Meanwhile, osteoporosis and fractures were also common. Therapeutic measures should be targeted at individuals, which needs further study. Through meta-analysis, we found that glucocorticoids have some negative effects on the bone health of subjects with rheumatoid arthritis. Therefore, when using glucocorticoids to treat rheumatoid arthritis, we should take strategic measures to prevent the decline of bone quality.

Investigation and Management of Bone Mineral Density Following Hematopoietic Cell Transplantation: A Survey of Current Practice by the Transplant Complications Working Party of the European Society for Blood and Marrow Transplantation

Reduced bone mineral density (BMD) is a well-recognized complication of hematopoietic cell transplantation (HCT), with significant drops in BMD occurring within the first 12 months after HCT. Guidance on identifying and managing this complication is available in several published guidelines. In this study, we investigated current practices in the investigation and management of low BMD in centers registered with the European Society for Blood and Marrow Transplantation (EBMT). A questionnaire about bone health was sent to all registered centers, and responses were received from 99 centers in 25 countries (52%) currently registered with the EBMT. Our data highlight considerable heterogeneity in practices across European centers in relation to investigations, management, and use of guidelines. Our data demonstrate the need for better dissemination and implementation of existing guidelines and also for the development of multidisciplinary guidelines with input from all relevant stakeholders.

[Vitamin D metabolism in hypercorticism and acromegaly]

Due to the high prevalence of low vitamin D levels in the overwhelming majority of regions of the world and discovery of extra-skeletal effects of vitamin D, the issue of maintaining adequate levels of vitamin D in the blood remains extremely relevant, especially in people with high risk of severe deficiency. To date, few studies have been performed on the features of vitamin D metabolism in disorders such as hypercorticism and acromegaly. However, vitamin D deficiency in such patients, according to available literature, may be more widespread and more pronounced than in general population. It is now recommended to use standard prophylactic and therapeutic doses of vitamin D for the treatment of these diseases, which may not satisfy the therapeutic goals specific to each disease. This review provides information on normal vitamin D metabolism, as well as literature data on the possible relationship and mutual influence between these endocrinopathies and vitamin D metabolism.

An Electronic Clinical Decision Support System for the Management of Low Back Pain in Community Pharmacy: Development and Mixed Methods Feasibility Study

Background

People with low back pain (LBP) in the community often do not receive evidence-based advice and management. Community pharmacists can play an important role in supporting people with LBP as pharmacists are easily accessible to provide first-line care. However, previous research suggests that pharmacists may not consistently deliver advice that is concordant with guideline recommendations and may demonstrate difficulty determining which patients require prompt medical review. A clinical decision support system (CDSS) may enhance first-line care of LBP, but none exists to support the community pharmacist–client consultation.

Objective

This study aimed to develop a CDSS to guide first-line care of LBP in the community pharmacy setting and to evaluate the pharmacist-reported usability and acceptance of the prototype system.

Methods

A cross-platform Web app for the Apple iPad was developed in conjunction with academic and clinical experts using an iterative user-centered design process during interface design, clinical reasoning, program development, and evaluation. The CDSS was evaluated via one-to-one user-testing with 5 community pharmacists (5 case vignettes each). Data were collected via video recording, screen capture, survey instrument (system usability scale), and direct observation.

Results

Pharmacists’ agreement with CDSS-generated self-care recommendations was 90% (18/20), with medicines recommendations was 100% (25/25), and with referral advice was 88% (22/25; total 70 recommendations). Pharmacists expressed uncertainty when screening for serious pathology in 40% (10/25) of cases. Pharmacists requested more direction from the CDSS in relation to automated prompts for user input and page navigation. Overall system usability was rated as excellent (mean score 92/100, SD 6.5; 90th percentile compared with similar systems), with acceptance rated as good to excellent.

Conclusions

A novel CDSS (high-fidelity prototype) to enhance pharmacist care of LBP was developed, underpinned by clinical practice guidelines and informed by a multidisciplinary team of experts. User-testing revealed a high level of usability and acceptance of the prototype system, with suggestions to improve interface prompts and information delivery. The small study sample limits the generalizability of the findings but offers important insights to inform the next stage of system development.

How Do Glucocorticoids Used in Rheumatic Disease Affect Body Weight? A Narrative Review of the Evidence

Glucocorticoids (GCs) are widely used to effectively treat inflammatory disease, but GCs have a number of recognized side effects. Patients and clinicians view these side effects differently, with clinicians most concerned with serious side effects such as osteoporosis and diabetes mellitus. Consequently, these side effects are well researched with clinical guidelines and recommendations. A side effect of particular concern to patients is weight gain, but this topic has not been well researched, and consequently clinicians find it difficult to provide patients with accurate information about the potential of weight gain. The aim of this review is to provide an overview of GC use specifically in rheumatic disease, patient views on GC therapy, and GC-induced weight gain. We will discuss the evidence, including the extent and the impact of weight gain on the patient, and highlight areas that warrant further investigation.

Comorbidities associated with psoriatic arthritis: Review and update

Psoriatic arthritis is an inflammatory arthropathy frequently associated with psoriasis and several other comorbidities. The goal of this review is to summarize the available evidence on the epidemiology, clinical implications, pathological mechanisms proposed, and screening and management recommendations for the comorbidities related with PsA. Reported comorbidities include cardiovascular disease, metabolic syndrome, obesity, diabetes mellitus, dyslipidemia, inflammatory bowel disease, fatty liver disease, uveitis, kidney disease, infections, osteoporosis, depression, central sensitization syndrome, and gout. Given that these comorbidities may affect both clinical outcomes and the management for these patients, their recognition and monitoring by all health-care providers caring for patients with psoriatic arthritis is of utmost importance.

2020 Brazilian Thoracic Association recommendations for the management of asthma

The pharmacological management of asthma has changed considerably in recent decades, as it has come to be understood that it is a complex, heterogeneous disease with different phenotypes and endotypes. It is now clear that the goal of asthma treatment should be to achieve and maintain control of the disease, as well as to minimize the risks (of exacerbations, disease instability, accelerated loss of lung function, and adverse treatment effects). That requires an approach that is personalized in terms of the pharmacological treatment, patient education, written action plan, training in correct inhaler use, and review of the inhaler technique at each office visit. A panel of 22 pulmonologists was invited to perform a critical review of recent evidence of pharmacological treatment of asthma and to prepare this set of recommendations, a treatment guide tailored to use in Brazil. The topics or questions related to the most significant changes in concepts, and consequently in the management of asthma in clinical practice, were chosen by a panel of experts. To formulate these recommendations, we asked each expert to perform a critical review of a topic or to respond to a question, on the basis of evidence in the literature. In a second phase, three experts discussed and structured all texts submitted by the others. That was followed by a third phase, in which all of the experts reviewed and discussed each recommendation. These recommendations, which are intended for physicians involved in the treatment of asthma, apply to asthma patients of all ages.

Estimation of Long-Term Efficacy of Denosumab Treatment in Postmenopausal Women With Osteoporosis: A FRAX- and Virtual Twin-Based Post Hoc Analysis From the FREEDOM and FREEDOM Extension Trials

The 3-year placebo-controlled FREEDOM (Fracture REduction Evaluation of Denosumab in Osteoporosis Every 6 Months) trial established the antifracture efficacy of denosumab in postmenopausal women with osteoporosis. The 7-year open-label extension demonstrated that denosumab treatment for up to 10 years was associated with low rates of adverse events and low fracture incidence. The extension lacked a long-term control group, thus limiting the ability to fully evaluate long-term efficacy. This analysis provides a quantitative estimate of the long-term antifracture efficacy of denosumab based on two approaches: comparison with FRAX®- (Fracture Risk Assessment Tool-) and virtual twin-estimated 10-year fracture rates. Subjects who were randomized to denosumab in the FREEDOM trial, continued into the Extension study, completed the 10-year visit, and missed ≤1 dose in the FREEDOM trial and ≤1 dose in the Extension (n = 1278) were included in the analysis. The 10-year observed cumulative incidence of major osteoporotic fracture (MOF) and hip fractures was compared with the 10-year fracture probability predicted at baseline by FRAX, a computer-based fracture risk algorithm, and with that estimated for a hypothetical cohort of 10-year placebo controls (virtual twins). The observed 10-year fracture incidence was lower than the 10-year probability predicted by FRAX for both MOF (10.75% [95% CI, 9.05 to 12.46] versus 15.63% [95% CI, 15.08 to 16.18], respectively), and hip fractures (1.17% [95% CI, 0.58 to 1.76] versus 5.62% [95% CI, 5.28 to 5.97], respectively). The observed fracture incidence was also lower than the fracture rate estimated in a hypothetical cohort of 10-year placebo controls for MOF (23.13% [95% CI, 17.76 to 28.87]; relative risk 0.49 [95% CI, 0.36 to 0.64]). These data support the long-term efficacy of denosumab in reducing MOF and hip fractures in postmenopausal women with osteoporosis. © 2020 The Authors.

[Woman's asthma throughout life: Towards a personalized management?]

In a woman's life, asthma can affect her in a variety of ways, with the onset of premenstrual asthma currently under-diagnosed. It is estimated that about 20% of women with asthma have premenstrual asthma, which is more common in patients with severe asthma. Women with asthma are at high risk of exacerbations and of severe asthma. Asthma is the most common chronic disease during pregnancy with potential maternal and foetal complications. Asthma medications are safe for the foetus and it is essential to continue pre-existing treatment and adapt it to the progress of asthma during the pregnancy. Sex steroids modulate the structure and function of bronchial and immune cells. Understanding their role in asthma pathogenesis is complicated by the ambivalent effects of bronchodilating and pro-inflammatory oestrogens as well as the diversity of response to their association with progesterone. Menopausal asthma is a clinical entity and is part of one of the phenotypes of severe non-allergic and low steroid-sensitive asthma. Targeted assessment of the domestic and professional environment allows optimization of asthma management.

Vitamin D and bisphosphonate therapy in systemic lupus erythematosus patients who receive glucocorticoids: are we offering the best care?

OBJECTIVE

This study aimed to evaluate management practices for glucocorticoid (GC)-induced osteoporosis (GIOP) in systemic lupus erythematosus (SLE) patients using 2017 American College of Rheumatology guidelines as a gold standard.

METHODS

We conducted a retrospective cohort study using a clinical database from the years 2011 to 2016. SLE cases with >90 days continuous prednisone use at doses of ≥7.51 mg daily were identified. Osteoporosis risk factors were assessed via chart review. The Fracture Risk Assessment (FRAX) score was estimated for patients > 40 years of age. Vitamin D, bisphosphonate prescriptions, and osteoporotic (OP) fractures were ascertained through chart review. A classification tree was used to identify the key patient-related predictors of bisphosphonate prescription.

RESULTS

A total of 203 SLE patients met the inclusion criteria. The recommended dose of vitamin D supplement was prescribed to 58.9% of patients < 40 years of age and 61.5% of patients ≥ 40 years of age. Among patients aged ≥ 40 years, 25% were prescribed bisphosphonates compared to 36% who met indications for bisphosphonates per the ACR guidelines. Another 10% were prescribed a bisphosphonate, despite not having indication per the ACR guidelines, which was considered as overtreatment. Among patients aged ≥ 40 years, older age and a higher FRAX score for major OP fracture and hip fracture predicted bisphosphonate prescription. In a classification tree analysis, patients with FRAX scores (for major OP fracture) of ≥ 23.5% predicted bisphosphonate prescription in this SLE population. Among patients who had OP fractures in the follow-up period, nine (6.50%) were inpatients receiving appropriate GIOP care versus 12 (13.6%) who were inpatients not receiving ACR-appropriate care (p = 0.098).

CONCLUSIONS

In clinical practice, fewer SLE patients with or at risk for GIOP are prescribed vitamin D and bisphosphonates than recommended by the 2017 ACR guidelines. Also, in this study, another 10% were prescribed a bisphosphonate, despite not having an indication per the ACR guidelines. Patients were most likely to receive a bisphosphonate prescription if they had a major OP FRAX score of > 23.5%.

Impact of Rheumatoid Arthritis and Its Management on Falls, Fracture and Bone Mineral Density in UK Biobank

Objectives: Rheumatoid arthritis (RA) is a systemic chronic inflammatory disease which presents with polyarthritis in addition to extra-articular manifestations. Historically, studies have shown a link between RA and adverse musculoskeletal outcomes but these studies were reported before the widespread use of biologic therapies. The aim of this study was therefore to investigate associations between RA, RA medications and bone mineral density, falls and fractures, using UK Biobank data. Methods: Diagnosis of RA was made using Hospital Episode Statistics (HES) ICD-10 coding. We assessed RA relationships with estimated bone mineral density (eBMD) from heel quantitative ultrasound measurements, self-reported falls (in last year) and HES recorded fracture, adjusted for age, ethnicity, BMI, smoking status, and physical activity. Results: Of 502,543 participants, 3849 (1.4%) of women and 1643 (0.7%) of men had a diagnosis of RA. Median age of the participants was 57 years (IQR 50-63) in women and 58 (IQR 50-64) in men. RA was associated with lower eBMD (men: β -0.244, 95% CI -0.378, -0.110 p < 0.001; women: β -0.217, 95% CI -0.297, -0.138 p < 0.001) a reported fall in the last year (men: OR 1.54, 95% CI 1.26, 1.87 p < 0.001; women: OR 1.36, 95% CI 1.19, 1.56 p < 0.001) and fracture in women (OR 1.76, 95% CI 1.43, 2.16 p < 0.001). Corticosteroid therapy in men (β -0.934, 95% CI -1.565, -0.304 p = 0.004) and disease modifying anti-rheumatic drug (DMARD) use in both sexes (men: β -0.437, 95% CI -0.761, -0.112 p = 0.008; women: β -0.243, 95% CI -0.421, -0.065 p = 0.007), but not biologic therapy, were associated with a lower eBMD with RA. Conclusions: RA was associated with lower eBMD, increased falls and fracture. Corticosteroid and DMARD therapy, but not biologic therapy, were associated with lower eBMD.

Results of the standard set for pulmonary sarcoidosis: feasibility and multicentre outcomes

Our study presents findings on a previously developed standard set of clinical outcome data for pulmonary sarcoidosis patients. We aimed to assess whether changes in outcome varied between the different centres and to evaluate the feasibility of collecting the standard set retrospectively.

This retrospective observational comparative benchmark study included six interstitial lung disease expert centres based in the Netherlands, Belgium, the UK and the USA. The standard set of outcome measures included 1) mortality, 2) changes in pulmonary function (forced vital capacity (FVC), forced expiratory volume in 1 s, diffusing capacity of the lung for carbon monoxide), 3) soluble interleukin-2 receptor (sIL-2R) change, 4) weight changes, 5) quality-of-life (QoL) measures, 6) osteoporosis and 7) clinical outcome status (COS). Data collection was considered feasible if the data were collected in ≥80% of all patients.

509 patients were included in the retrospective cohort. In total six patients died, with a mean survival of 38±23.4 months after the diagnosis. Centres varied in mean baseline FVC, ranging from 110 (95% CI 92–124)% predicted to 99 (95% CI 97–123)% pred. Mean baseline body mass index (BMI) of patients in the different centres varied between 27 (95% CI 23.6–29.4) kg·m⁻² and 31.8 (95% CI 28.1–35.6) kg·m⁻². 310 (60.9%) patients were still on systemic therapy 2 years after the diagnosis. It was feasible to measure mortality, changes in pulmonary function, weight changes and COS. It is not (yet) feasible to retrospectively collect sIL-2R, osteoporosis and QoL data internationally.

This study shows that data collection for the standard set of outcome measures for pulmonary sarcoidosis was feasible for four out of seven outcome measures. Trends in pulmonary function and BMI were similar for different hospitals when comparing different practices.

Clinical outcome data have been used to compare outcomes in pulmonary sarcoidosis patients and improve care delivery. Data collection for the standard set of outcome measures for pulmonary sarcoidosis was feasible for four out of seven outcome measures.http://bit.ly/2F8bQ6s

Effect of vitamin D on serum markers of bone turnover in SLE in a randomised controlled trial

Objective

Bone health in SLE is adversely affected by vitamin D deficiency, inflammatory cytokines and glucocorticoid use. We hypothesised that vitamin D supplementation would increase markers of bone formation and decrease markers of bone resorption in SLE subjects.

Methods

We studied 43 vitamin D-deficient SLE subjects who participated in a 12-week randomised controlled trial of 2000–4000 IU/day vitamin D supplementation versus placebo. Subjects had inactive SLE (SLE Disease Activity Index ≤4) and were taking <20 mg prednisone daily at baseline. We assayed baseline and week 12 serum 25-hydroxyvitamin D, N-terminal propeptide of type 1 collagen (P1NP) and C-telopeptide (CTX). We tested the effect of vitamin D versus placebo on change (Δ) in P1NP and ΔCTX in an intention-to-treat analysis. Secondary analyses evaluated whether vitamin D affected bone turnover among subjects achieving vitamin D repletion (≥30 ng/mL) or currently taking glucocorticoids.

Results

28 subjects were randomised to vitamin D and 15 to placebo. Mean age was 39 years and 40% were using glucocorticoids at enrolment. Repletion was achieved by 46% in the vitamin D group versus none in the placebo group. Changes in bone turnover markers were not significantly different in the vitamin D group versus placebo group (median ΔP1NP −0.2 vitamin D group vs −1.1 placebo group (p=0.83); median ΔCTX +3.5 vitamin D group vs −37.0 placebo group (p=0.50)). The effect of vitamin D did not differ based on achieving vitamin D repletion or baseline glucocorticoid use.

Conclusion

Vitamin D supplementation did not affect the 12-week change in bone turnover markers among SLE subjects in this trial.

Improving bone mineral density screening in patients with inflammatory bowel disease: a quality improvement report

The prevalence of osteopenia and osteoporosis in patients with inflammatory bowel disease (IBD) is estimated between 17% and 41%, partly due to repeat courses of glucocorticoids which enhance the risk for bone disease. Multiple gastroenterological and endocrine societies have established guidelines for bone mineral density (BMD) screening in patients with IBD, with estimates suggesting providers vary in their adherence. We aimed to improve the rate of BMD screening in patients with IBD in a large academic outpatient practice. Using the Plan-Do-Study-Act (PDSA) model, we first conducted a retrospective review and determined that only 10.8% of patients with IBD in our practice were adequately undergoing BMD screening. Over the course of five PDSA cycles, we conducted three interventions focusing on education and provider reminders. Through an informative lecture, a flyer and an electronic medical record-based prompt, we were able to increase our rate of BMD screening to 81.8%. Current rates of BMD screening in patients with IBD are not adequate. We demonstrate a simple quality improvement initiative that successfully improved our adherence to standards of practice.
