The diagnosis and management of systemic autoimmune rheumatic disease-related interstitial lung disease: British Society for Rheumatology guideline scope.

Interstitial lung disease (ILD) is a significant complication of many systemic autoimmune rheumatic diseases (SARDs), although the clinical presentation, severity and outlook may vary widely between individuals. Despite the prevalence, there are no specific guidelines addressing the issue of screening, diagnosis and management of ILD across this diverse group. Guidelines from the ACR and EULAR are expected, but there is a need for UK-specific guidelines that consider the framework of the UK National Health Service, local licensing and funding strategies. This article outlines the intended scope for the British Society for Rheumatology guideline on the diagnosis and management of SARD-ILD developed by the guideline working group. It specifically identifies the SARDs for consideration, alongside the overarching principles for which systematic review will be conducted. Expert consensus will be produced based on the most up-to-date available evidence for inclusion within the final guideline. Key issues to be addressed include recommendations for screening of ILD, identifying the methodology and frequency of monitoring and pharmacological and non-pharmacological management. The guideline will be developed according to methods and processes outlined in Creating Clinical Guidelines: British Society for Rheumatology Protocol version 5.1.

Should All Patients Trial Subcutaneous Methotrexate Prior to Commencing Biologic Therapy? A Real World Study.

Introduction: Methotrexate (MTX) is the bed rock of inflammatory arthritis management. However, intolerance is a limiting factor for drug optimisation and retention. There is data to suggest subcutaneous (SC) MTX is better tolerated. It is less clear whether this strategy is effective in those where the oral preparation is inefficacious and its potential to avoid escalation to biologic therapy. Objectives: To analyse the reasons for switching to SC MTX in a real-world setting, clinical outcomes achieved and proportion requiring biologic prescription. Materials and Methods: A retrospective survey of patients prescribed SC MTX in a university teaching hospital identified 352 patients. 298 switched from oral to SC MTX- 164 stopped oral MTX due to side effects, 134 stopped due to inefficacy, and 54 started SC MTX as first line therapy. 103 patients progressed to biologic therapy. Rheumatoid arthritis (RA): DAS-28 improved from a mean of 4.06 (0.63-8.06) to 2.83 (0.14-7.32) following the switch (p<0.0001). Psoriatic arthritis (PsA): total joint count improved from a mean of 7 (0-42) to 2 (0-25) (p<0.0001). Swollen joint count improved from a mean of 2 (0-26) to 1 (0-6) (p=0.09). Discussion: SC MTX is an effective solution for RA and PsA, irrespective of whether oral MTX is inefficacious or intolerable. Where oral MTX was ineffective, a switch to SC achieved low disease activity despite multi-morbidity, long disease course and protracted oral MTX exposure. This intervention prevented over two-thirds of patients requiring biologics. SC MTX is a durable strategy with excellent disease outcomes and substantial economic benefits.

Approaches to optimising access to NICE-approved biologic anti-TNFs for patients with rheumatoid arthritis with moderately active disease.

BACKGROUND: Rheumatoid arthritis (RA) is a chronic inflammatory disease that is associated with joint pain and stiffness. Biologics represent some of the most effective treatments for RA, but previous guidance from the National Institute for Health and Care Excellence (NICE) has limited their use to patients with severely active disease. This has meant patients with moderately active RA have been treated as if they have an acceptable disease state, despite many cases where the inflammation has a major impact on joint damage, mobility, pain and quality of life. However, recent guideline changes (NICE TA715) have approved the use of three biologics - adalimumab, etanercept and infliximab - for the treatment of moderately active RA. MAIN BODY: In response to these changes, we have held discussions with medical teams from across the UK to consider the main implications for implementation of these new recommendations, as well as any differences in approach that may exist at a local level. Several key challenges were identified. These included establishing methods of educating both physicians and patients concerning the new availability of the biologic treatments, with suggestions of various organisations that could be approached to circulate informative material. Identifying which patients with moderately active RA stand to benefit was another discussion topic. Relying solely on scoring systems like Disease Activity Score in 28 Joints (DAS28) was acknowledged to have limitations, and alternative complementary approaches such as ultrasound, as well as assessing a patient's co-morbidities, could also be useful tools in determining those who could benefit from biologics. An additional challenge for the process of patient identification has been the increase in the use of telemedicine consultations in response to the coronavirus disease 2019 (COVID-19) pandemic. More use of patient-reported outcomes was raised as one possible solution, and the importance of maintaining up-to-date databases on patient disease scores and treatment history was also stressed. CONCLUSION: While challenges exist in education and identifying patients who may benefit from the use of biologics, the NICE TA715 recommendations hold great potential in addressing an unmet need for the treatment of moderate RA.

Biomarkers Predict In-Hospital Major Adverse Cardiac Events in COVID-19 Patients: A Multicenter International Study.

BACKGROUND: The COVID-19 pandemic carries a high burden of morbidity and mortality worldwide. We aimed to identify possible predictors of in-hospital major cardiovascular (CV) events in COVID-19. METHODS: We retrospectively included patients hospitalized for COVID-19 from 10 centers. Clinical, biochemical, electrocardiographic, and imaging data at admission and medications were collected. Primary endpoint was a composite of in-hospital CV death, acute heart failure (AHF), acute myocarditis, arrhythmias, acute coronary syndromes (ACS), cardiocirculatory arrest, and pulmonary embolism (PE). RESULTS: Of the 748 patients included, 141(19%) reached the set endpoint: 49 (7%) CV death, 15 (2%) acute myocarditis, 32 (4%) sustained-supraventricular or ventricular arrhythmias, 14 (2%) cardiocirculatory arrest, 8 (1%) ACS, 41 (5%) AHF, and 39 (5%) PE. Patients with CV events had higher age, body temperature, creatinine, high-sensitivity troponin, white blood cells, and platelet counts at admission and were more likely to have systemic hypertension, renal failure (creatinine ≥ 1.25 mg/dL), chronic obstructive pulmonary disease, atrial fibrillation, and cardiomyopathy. On univariate and multivariate analysis, troponin and renal failure were associated with the composite endpoint. Kaplan-Meier analysis showed a clear divergence of in-hospital composite event-free survival stratified according to median troponin value and the presence of renal failure (Log rank p < 0.001). CONCLUSIONS: Our findings, derived from a multicenter data collection study, suggest the routine use of biomarkers, such as cardiac troponin and serum creatinine, for in-hospital prediction of CV events in patients with COVID-19.

Does biologic survival depend on co-prescribed methotrexate dose in established rheumatoid arthritis? A real-world study.

OBJECTIVE: Several seminal studies have suggested that a combination therapy of biologics with conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) improve disease outcomes in rheumatoid arthritis (RA). Hence, most guidelines reflect this practice. It has also been shown that methotrexate (MTX) at a dose of 8-10 mg/week is perhaps sufficient to achieve better outcomes in early RA. However, it is not clear whether this strategy enhances biologic retention in the patients with established RA. We present a real-world retrospective study to investigate whether csDMARD co-prescription improves biologic retention and the optimal dose to preserve such response. MATERIALS AND METHODS: All patients prescribed biologic therapy for RA at our center between 2003 and 2017 were identified through the departmental database. They were split into five groups based on a weekly MTX dose (≤7.5 mg, 10-17.5 mg, ≥20 mg), other csDMARD prescription, or biologic monotherapy. The one-way analysis of variance model for independent values was utilized to ascertain the significance of data. The Mann-Whitney two-tailed U test was employed to determine the significance of relationship between the monotherapy group and other arms. The significance level was predefined at 0.05. RESULTS: A total of 168 patients with 198 biologic events were included. The mean age was 59.4 years (range, 24-90 years). 78% were women. The mean disease duration was 155.6 months (range, 15-491). There was a statistically significant difference (p=0.03) in biologic retention among the five arms. Compared to monotherapy, the data remained significant for ≥20 mg MTX and csDMARD groups; however, the biologic retention in the other two MTX arms was not significant. There was no significant relationship among groups for DAS28 improvement (p=0.24). CONCLUSION: Our results suggest that to improve biologic retention, the MTX dose should be increased to 20 mg a week or more, and, in people with MTX intolerance, csDMARDs co-presciption can be an alternative strategy. Maintenance with a low-to-moderate MTX dose can lead to poorer retention rates.

Giant Cell Hepatitis - A Rare Association with Connective Tissue Disease.

A 68-year-old gentleman presented to hepatology department with asymptomatic year-long history of stably deranged liver function tests. His peak alkaline phosphatase (ALP), was 828 with alanine transaminase (ALT) of 141. Full liver workup was negative; hence, a liver biopsy was organised, which confirmed giant cell hepatitis (GCH). A computed tomography (CT) scan revealed non-specific interstitial pneumonitis (NSIP) pattern interstitial lung disease supported by lung function tests. Antibody testing showed strongly positive antinuclear antibody (ANA) with anti-polymyositis/scleroderma (anti-PM-SCL) antibody. Clinical picture was in keeping with likely undifferentiated connective tissue disease (UCTD) with polyarthralgia, early morning stiffness, Raynaud's and nailfold infarcts with capillaritis on nail bed examination. Further testing confirmed triple-positive antiphospholipid antibodies twice 12 weeks apart (immunoglobulin M [IgM] anti beta-2 glycoprotein antibodies, lupus anticoagulant and IgM anticardiolipin antibody). He was treated with mycophenolate and hydroxychloroquine with resolution of symptoms. Giant cell hepatitis is uncommon, with only 100 cases reported worldwide. To our knowledge, this is the only report of GCH in the context of UCTD, highlighting the significance of careful evaluation of liver disease overlap and the successful role of mycophenolate mofetil (MMF) in this setting.

Crystallising the role of adrenocorticotrophic hormone in the management of acute gout: a review.

OBJECTIVES: Acute gout is traditionally treated with NSAIDs, corticosteroids, and colchicine. However, the presence of comorbid conditions and advancing age, often seen in hospitalised patients, may prevent their use. We reviewed the published data on the use of ACTH in the treatment of acute gouty arthritis. METHODS: A search was performed up to June 2017. We included clinical trials or case studies/series where ACTH had been administered in human subjects as a treatment for acute gout or pseudogout. RESULTS: Data consistently demonstrated ACTH to be fast-acting, typically relieving the painful symptoms of acute gout within 24 h of treatment. Furthermore, the average number of days needed to achieve 100% resolution of gout symptoms in patients treated with ACTH was similar to those of the corticosteroid triamcinolone. Retrospective data confirm the efficacy of ACTH or the synthetic analogue Synacthen in the treatment of acute gout in patients with comorbidities such as cardiovascular disease, chronic kidney disease, and hypertension, including those who were hospitalised, with all patients responding after 1-3 doses. ACTH appears to be well-tolerated with side effects being minor and transient in nature. Importantly, ACTH/Synacthen has no clinically significant effect on glucose and potassium levels or blood pressure. Clinical evidence from available case studies supports these findings. CONCLUSIONS: ACTH is a fast acting, efficacious and well-tolerated option for patients with acute gout when traditional therapies have failed or are contraindicated. However, large, carefully designed, randomised controlled trials are required to confirm these findings.

Adherence to biologic therapy - Does it vary with ethnicity?

BackgroundPoor adherence to therapy remains a significant barrier to improving clinical outcomes in rheumatic diseases and carries a major financial burden. It has been linked to medication related patient beliefs, which were reported to differ between ethnic groups. Little is known about these variations in biologic therapies cohorts. The purpose of this study was to identify potential determinants of adherence to biologic drugs including an assessment of the influence of beliefs about medicines and compare determinants of adherence between patients of Caucasian versus other ethnicities (OE). Relationship of adherence to disease outcome was further explored. MethodsA prospective survey was undertaken of patients with inflammatory arthritis prescribed self-administered subcutaneous biologic therapies at our centre. Data were collected using a) self reported adherence b) five item compliance questionnaire for Rheumatology (CQR5) and c) Beliefs about Medications questionnaire (BMQ) specific-five items each for necessity and concern scales. The replies were assessed against the disease activity score measured on the day of recruitment to the survey. Results80 patients contributed to the survey. 90% were prescribed TNF inhibitors. 40 patients were of Caucasian origin and 40 belonged to OE-predominantly of South Asian descent (85%). Disease activity score (DAS) was significantly higher in OE patients with 3.7 (standard deviation (SD) 1.3) compared to Caucasian patients with a DAS of 2.9 (1.6) (p = 0.031). Negative beliefs (i.e. higher concern scale scores) about therapy were significantly more prevalent (24/40) (60%) in the OE group compared to the Caucasian cohort (14/40 (35%) (p = 0.043). 17/40 (42.5%) of OE patients were poorly adherent to biologic therapy compared to 12/40 (30%) of Caucasian participants (p = 0.308). Most respondents (68/80, 85%) agreed that their biologic therapies were necessary for their health. Amongst 12/80 (15%) who disagreed, only two were in the non-adherent group. ConclusionTo our knowledge, this is the first study to demonstrate ethnic differences in disease activity score and related negative beliefs regarding subcutaneous biologic therapies in people with rheumatic diseases.

Cupping (Hijama) Treatment: Benign or Sinister?

Cupping treatment is on the rise in the Western world as an alternative medicine modality.We present a hitherto unreported complication of bilateral subdural hemorrhage associated with this therapy, highlighting the need for vigilance in patients presenting with headache because they may get misdiagnosed unless history for such therapies is explored.

Biologic therapy for inflammatory arthritis and latent tuberculosis: real world experience from a high prevalence area in the United Kingdom.

Biologic therapies have resulted in a sea change in the management of inflammatory arthritis; however, a higher risk of opportunistic infection, particularly tuberculosis (TB), is well recognised. This has led to the development of TB screening guidelines. The aim of this study was to investigate the prevalence of latent TB in patients prescribed biologic therapy in an endemic area (prevalence of TB 50/100,000) and to assess the risk of subsequent reactivation. Retrospective case note review of all patients with inflammatory arthritis ever prescribed biologic therapy between 1998 and 2014 at our centre. Two hundred ninety-nine patients (109 men, 190 women) who had ever been prescribed biologic therapy over a 16-year period were included. Mean age upon commencing the biologic therapy was 51 years. Two hundred eighteen (73 %) patients were Caucasian with remaining from ethnic minorities. Two hundred thirty-nine (80 %) prescriptions were for TNF inhibitors. Median duration of biologic therapy was 4.2 years for those who remained on treatment prior to stopping or switching therapies. During 1998-2007, 112 patients underwent clinical assessment, chest X-ray and check for BCG scar. One patient of Asian origin developed extrapulmonary TB within 6 weeks of adalimumab initiation. Following a year of anti-TB treatment, he restarted the biologic therapy with no ill effects. One hundred eighty-seven participants (who started on biologic therapy between 2008 and 2014) underwent additional interferon gamma release assays (IGRA) testing as part of a new TB screening protocol (T-spot test). Eighteen (10 %) had positive test with normal chest X-rays. Six patients were white, nine of Asian origin and three others. Three Caucasian patients had a borderline result. All had 3 months of isoniazid and rifampicin with simultaneous prescription of biologic agent (13 had TNF antagonist, 5 rituximab and 3 tocilizumab). No cases of active TB infection were observed. Overall prevalence of latent TB in patients with inflammatory arthritis prescribed biologic therapy in an endemic area is 10 %. The risk warrants careful screening and monitoring in all patients. Adherence to strict screening protocol reduces the risk of active TB infection irrespective of the biologic therapy employed.

Pulmonary complications of biological therapies in children and adults with rheumatic diseases.

The management of rheumatic conditions, including those occurring in children, has improved dramatically over the last decade following the introduction of biologic disease-modifying anti-rheumatic drugs (bDMARDS) into the therapeutic arsenal. The benefits have been realised in multiple aspects of disease including signs and symptoms, bone and cartilage destruction, disability and quality of life. Overall, bDMARDS have an acceptable safety profile in the short to medium term in adults and children, however, that following longer term use remains unclear. As these drugs target key signalling molecules and cells of the immune system, adverse events are not unanticipated. In this review we will discuss pulmonary complications of biologic therapies used in the management of rheumatic diseases in both children and adults.

What do we know about juvenile idiopathic arthritis and vitamin D? A systematic literature review and meta-analysis of current evidence.

Over the last decade vitamin D (Vit D) has been the focus of considerable interest as a potential immunomodulator in a variety of conditions including autoimmune disease. Its influence in juvenile idiopathic arthritis (JIA) however is unclear. We therefore wished to clarify a possible link with the currently available evidence. A systematic literature review was undertaken using Embase, Cochrane and Medline for manuscripts up to May 2011. Search results were then assessed by two independent reviewers and relevant articles were further screened by full text review. Only those specifically reporting Vit D levels or its supplementation in JIA (ages between 0 and 18 years) were selected. Meta-analysis was performed where possible with those papers reporting similar data and analysis techniques. In total, 19 papers (n = 745) were included in the review. Fourteen papers quoted 25(OH)D levels within their study groups with a mean of 24.56 ng/ml (range, 11.5-56.4 ng/ml) in a total of 529 children. Eleven papers quoted 1,25(OH)2D levels with a mean of 31.09 pg/ml (range 6.1-65.0 pg/mol) in a total of 518 children. Three studies reporting the prevalence of Vit D deficiency in their cohorts found that up to 82 % of children had insufficient levels. Five papers reported Vit D levels by JIA subtype and showed lower levels of both 25(OH)D [mean 15.35, range 8.5-24.5 ng/ml] and 1,25(OH)2D [ mean 22.89, range 5.6-50 pg/ml] in systemic JIA. Four papers reported Vit D supplementation in JIA however the treatment effect was unclear. At present no clear evidence exists to support a link between Vit D level and JIA. Furthermore, the role of Vit D supplementation in the management of JIA is lacking. Despite Vit D levels appearing to be lower in JIA, interpretation is problematic as no agreed definition of Vit D deficiency exists in this population. A need remains therefore to standardise Vit D levels in the paediatric population and in JIA.

Same-day or historical ESR for disease activity score measurement: does it matter?

Several guidelines recommended routine use of Disease Activity Score-28 (DAS28) to monitor disease and the response to treatment for rheumatoid arthritis (RA). In practice, it may be appropriate to use historical erythrocyte sedimentation rate (ESR) values in place of same-day ESR, thereby preventing unnecessary delay in adjusting intervention. We asked whether ESR blood samples taken up to 3 months prior to the clinic appointment were adequate to accurately assess RA disease activity using the DAS28. RA patients (N = 66) who met the inclusion criteria were assessed at baseline and ESR obtained on the day of review to calculate the DAS28 and compared with the DAS28 derived from the latest previous ESR (mean interval, 38.6 days; range, 6-99 days). Limits of agreement (LoA) were used to assess the agreement between the DAS28 pairs. The mean age of the participants was 61.5 years (range, 20-83 years), with mean disease duration of 11.0 years (range, 0.1-40 years). Comparing the DAS28 using same-day ESR versus pre-recorded historical ESR showed a small statistical difference (mean, -0.09; 95 %CI, -0.1602 to -0.017) in the DAS28 score. The calculated LoA (-0.66 and 0.48) demonstrated acceptable agreement between DAS28 pairs, with 7.6 % of patients residing outside the LoA, all of whom had a significant treatment change. Disease misclassification occurred in 9.1 % of patients who were close to disease activity boundaries. Our results indicate that differences in the DAS28 due to a previous or same-day ESR are unlikely to be clinically significant for RA patients with established disease. A decision to adjust treatment therefore may be confidently made for most patients using the most recent ESR for calculating the DAS28, provided there was no major change in treatment since the last ESR measurement.
