The new 2010 ACR/EULAR criteria as predictor of clinical and radiographic response in patients with early arthritis

EULAR points to consider for the management of difficult-to-treat rheumatoid arthritis

OBJECTIVE

To develop evidence-based European Alliance of Associations for Rheumatology (EULAR) points to consider (PtCs) for the management of difficult-to-treat rheumatoid arthritis (D2T RA).

METHODS

An EULAR Task Force was established comprising 34 individuals: 26 rheumatologists, patient partners and rheumatology experienced health professionals. Two systematic literature reviews addressed clinical questions around diagnostic challenges, and pharmacological and non-pharmacological therapeutic strategies in D2T RA. PtCs were formulated based on the identified evidence and expert opinion. Strength of recommendations (SoR, scale A-D: A typically consistent level 1 studies and D level 5 evidence or inconsistent studies) and level of agreement (LoA, scale 0-10: 0 completely disagree and 10 completely agree) of the PtCs were determined by the Task Force members.

RESULTS

Two overarching principles and 11 PtCs were defined concerning diagnostic confirmation of RA, evaluation of inflammatory disease activity, pharmacological and non-pharmacological interventions, treatment adherence, functional disability, pain, fatigue, goal setting and self-efficacy and the impact of comorbidities. The SoR varied from level C to level D. The mean LoA with the overarching principles and PtCs was generally high (8.4-9.6).

CONCLUSIONS

These PtCs for D2T RA can serve as a clinical roadmap to support healthcare professionals and patients to deliver holistic management and more personalised pharmacological and non-pharmacological therapeutic strategies. High-quality evidence was scarce. A research agenda was created to guide future research.

Foot Involvement as the First Manifestation in Rheumatoid Arthritis Patients in Lahore

Objective

The objective of this study was to determine the involvement of the foot as the first manifestation in rheumatoid arthritis (RA).

Methods

This study was conducted on 100 patients who presented to the outpatient department of the Rheumatology Department at Fatima Memorial Hospital and College of Medicine and Dentistry in Lahore, Pakistan. The period of this cross-sectional study was three months - from October 2017 to December 2017. One hundred patients aged more than 16 years, who were diagnosed as cases of RA with foot involvement, and with a disease duration of less than two years (to minimize recall bias), were enrolled for the study.

Results

Out of the 100 patients, 20% were male and 80% were female. The mean age of the study population was 41.16 ± 12.343 years. Foot Involvement as the first manifestation was noted in 29 (29%) of the cases. The pattern of foot involvement shows a 59% forefoot involvement, 27% hindfoot involvement, and 14% midfoot involvement. Walking difficulty was most common in forefoot involvement (71.42% of cases), followed by hindfoot involvement (20% of cases), and least common in midfoot involvement (8.57% of cases) (p=0.0001).

Conclusion

Foot involvement as the first manifestation is quite common in RA and should not be ignored, especially in patients with large joint involvement sparing the hands.

The Pathogenesis of secondary forms of Autoimmune Inner Ear Disease (AIED): advancing beyond the audiogram data

INTRODUCTION

Autoimmune Inner Ear Disease (AIED) can be of a primary or secondary type. To date, a clear pathogenesis of the disease is still not available. Focusing on the secondary forms of AIED, the aim of this review is to (i) assess and describe the hearing involvement in patients affected by autoimmune diseases, (ii) describe the possible association between clinical features (among serological/laboratory data and disease activity/duration) and hearing impairment, (iii) show evidence connecting the AIED types with various etiopathogenetic mechanisms.

AREAS COVERED

A PRISMA-compliant systematic review was performed. Medline, Cochrane, Embase, and Cinahl were searched from 1 January 2015 through to 5 August 2020. Overall, 16 studies (involving 1043 participants) were included in the review. The data in the literature suggested that bilateral mild-to-moderate sensorineural hearing loss is a commonly reported clinical symptom of AIED.

EXPERT OPINION

Patients with systemic autoimmune disorders present a cochlear injury which might be associated with the humoral and/or cellular immune response against the inner ear. To date, AIED pathogenesis remains an open issue, due to the rarity of these clinical entities and due to the difficulties in investigating the inner ear immunology, considering the inner ear inaccessibility for tissue sampling.

Recurrent Pregnancy Loss in Women with Hashimoto's Thyroiditis with Concurrent Non-Endocrine Autoimmune Disorders

Background: An increased rate of recurrent miscarriage has been described in patients with autoimmune thyroid disease. However, there is a lack of studies that assess the rate of recurrent pregnancy loss (RPL) in patients with Hashimoto's thyroiditis (HT) isolated or with concurrent non-endocrine autoimmune disorders (NEAD). The objective of the study was to assess the rate of RPL in patients with HT isolated or accompanied with non-endocrine autoimmune diseases. Methods: This is a retrospective observational cohort study with a systematic review of the NEAD with concurrent HT in an outpatient Endocrinology Unit at a University Hospital. Among the 3480 consecutively examined women with HT, 87 patients met the criteria of RPL and represented the study group. Sixty-five of them had isolated HT and 22 women had HT+NEAD. Results: The rate of RPL in women with HT was 2.1% versus 5.64% observed in women with HT+NEAD (odds ratio = 2.78 [95% confidence interval 1.70-4.57]; p < 0.0001). On subdivision, this difference was still evident in euthyroid patients (p < 0.0001), while it disappeared in hypothyroid women (p = 0.21). The RPL did not correlate with the autoantibody concentrations nor in women with isolated HT nor in those with HT+NEAD. The presence of antiphospholipid syndrome (APS) explained RPL in 3 out of 22 (14%) patients with HT+NEAD, the remaining being related to different autoimmune disorders. Interestingly, even subtracting the patients with APS, RPL was more frequent in patients with poly-autoimmunity than in patients with isolated HT (p = 0.0013). Conclusions: The co-presence of NEAD is correlated with a higher risk of RPL in women with HT. The association with APS may explain only a fraction of RPL rate in patients with poly-autoimmunity.

The clinical phenotype of Graves' disease occurring as an isolated condition or in association with other autoimmune diseases

PURPOSE

Graves' disease (GD) can present as an isolated disease (iGD) or in association with other autoimmune diseases (aGD). The aim of this study, performed in two Endocrine referral centers settled in different geographical areas of Italy, was to compare the anthropometric, clinical, and biochemical phenotype of iGD patients with that of the aGD ones.

METHODS

Clinical history, physical examination data, serum levels of TSH, FT4, FT3, thyroglobulin (TgAb), thyroid-peroxidase (TPOAb) and TSH-receptor (TRAb) antibody, presence of Graves' orbitopathy (GO), and thyroid ultrasound examination at disease diagnosis were recorded.

RESULTS

68 aGD and 136 iGD patients were consecutively recruited. At diagnosis, aGD and iGD patients did not differ for F/M ratio, age at presentation, thyroid function parameters, serum levels of TRAb, TgAb, TPOAb, presence of GO, and thyroid volume. The serum levels of TRAb were strongly correlated with the circulating concentrations of both FT3 (ρ = 0.667; p < 0.0001) and FT4 (ρ = 0.628; p < 0.001) in iGD patient, but not in the aGD ones (FT3: ρ = 0.231; p = 0.058; FT4: ρ = 0.096; p = 0.435). Compared with iGD patients, the aGD ones displayed a higher rate of transition from the previous hypothyroidism to hyperthyroidism (χ² = 6.375; p = 0.012).

CONCLUSION

Despite similar anthropometric, clinical, and biochemical features at diagnosis, aGD patients display a higher rate of transition from a thyroid functional status to the other as compared with iGD patients.

EULAR recommendations for the management of rheumatoid arthritis with synthetic and biological disease-modifying antirheumatic drugs: 2019 update

OBJECTIVES

To provide an update of the European League Against Rheumatism (EULAR) rheumatoid arthritis (RA) management recommendations to account for the most recent developments in the field.

METHODS

An international task force considered new evidence supporting or contradicting previous recommendations and novel therapies and strategic insights based on two systematic literature searches on efficacy and safety of disease-modifying antirheumatic drugs (DMARDs) since the last update (2016) until 2019. A predefined voting process was applied, current levels of evidence and strengths of recommendation were assigned and participants ultimately voted independently on their level of agreement with each of the items.

RESULTS

The task force agreed on 5 overarching principles and 12 recommendations concerning use of conventional synthetic (cs) DMARDs (methotrexate (MTX), leflunomide, sulfasalazine); glucocorticoids (GCs); biological (b) DMARDs (tumour necrosis factor inhibitors (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab), abatacept, rituximab, tocilizumab, sarilumab and biosimilar (bs) DMARDs) and targeted synthetic (ts) DMARDs (the Janus kinase (JAK) inhibitors tofacitinib, baricitinib, filgotinib, upadacitinib). Guidance on monotherapy, combination therapy, treatment strategies (treat-to-target) and tapering on sustained clinical remission is provided. Cost and sequencing of b/tsDMARDs are addressed. Initially, MTX plus GCs and upon insufficient response to this therapy within 3 to 6 months, stratification according to risk factors is recommended. With poor prognostic factors (presence of autoantibodies, high disease activity, early erosions or failure of two csDMARDs), any bDMARD or JAK inhibitor should be added to the csDMARD. If this fails, any other bDMARD (from another or the same class) or tsDMARD is recommended. On sustained remission, DMARDs may be tapered, but not be stopped. Levels of evidence and levels of agreement were mostly high.

CONCLUSIONS

These updated EULAR recommendations provide consensus on the management of RA with respect to benefit, safety, preferences and cost.

Clinical and radiographic course of early undifferentiated arthritis under treatment is not dependent on the number of joints with erosions at diagnosis: results from the Swiss prospective observational cohort

Objective

To analyse whether early arthritis patients who do not fulfil the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) 2010 classification criteria for rheumatoid arthritis (RA) have a different course of the disease dependent on whether they can or cannot be classified as RA because of radiographic disease (EULAR task force) at diagnosis.

Methods

For this observational study within the Swiss RA cohort SCQM, we included patients with early undifferentiated arthritis (disease duration ≤1 year), who had not received any previous disease-modifying antirheumatic drugs (DMARDs). 2010 ACR/EULAR criteria negative patients were separated into two groups (radiographic vs non-radiographic arthritis) depending on whether or not they had radiographic changes defined as erosive disease by a EULAR task force (≥3 joints with erosions). The primary outcome measure was the radiographic progression detected employing the Ratingen erosion score. Health Assessment Questionnaire (HAQ) and DAS-28 were used as secondary outcome measures. The average observation period was 4 years.

Results

A total of 592 patients were analysed. 240 were not classifiable as RA by application of the 2010 ACR/EULAR criteria at baseline. In 57 patients, radiographs at the first visit were not available. 133 patients had radiographic arthritis and 50 non-radiographic arthritis. Treatment was initiated in all patients with DMARDs, mostly methotrexate. No differences in DAS-28 and HAQ scores were found during follow-up. The average erosion scores were higher among patients with initially radiographic arthritis throughout the study. The progression of erosion scores over time, however, was higher in patients with initially non-radiographic arthritis with less subsequent radiological progression (3.3 erosions/year vs 0.4, respectively, p<0.0001).

Conclusions

The clinical and radiographic course of early undifferentiated arthritis under treatment was not dependent on the presence of erosions in three or more joints (ie, the definition of radiographic disease by the EULAR task force) at diagnosis in our cohort.

Hearing status in patients with rheumatoid arthritis

Objective:

Rheumatoid arthritis is thought to induce conductive hearing loss and/or sensorineural hearing loss. This study evaluated the function of the middle ear and cochlea, and the related factors.

Methods:

Pure tone audiometry, speech reception thresholds, speech discrimination scores, tympanometry, acoustic reflexes, and distortion product otoacoustic emissions were assessed in rheumatoid arthritis patients and healthy volunteers.

Results:

Pure tone audiometry results revealed a higher bone conduction threshold in the rheumatoid arthritis group, but there was no significant difference when evaluated according to the sensorineural hearing loss definition. Distortion product otoacoustic emissions related prevalence of conductive or mixed hearing loss, tympanometry values, acoustic reflexes, and speech discrimination scores were not significantly different between the two groups. Sensorineural hearing loss was significantly more prevalent in patients who used azathioprine, cyclosporine and etanercept.

Conclusion:

Higher bone conduction thresholds in some frequencies were detected in rheumatoid arthritis patients that were not clinically significant. Sensorineural hearing loss is significantly more prevalent in refractory rheumatoid arthritis patients.

Does addition of glucocorticoids to the initial therapy influence the later course of the disease in patients with early RA? Results from the Swiss prospective observational registry (SCQM)

The main goal of this study was to analyse whether initial addition of glucocorticoid to DMARD therapy influences the long-term course of the disease in patients with early rheumatoid arthritis. All patients from the Swiss RA cohort SCQM with recent-onset arthritis (disease duration ≤1 year) were analysed. The exposure of interest was the use of glucocorticoids (GCs) at baseline. As primary outcome, we considered clinical and radiographic disease progression, assessed by the disease activity (disease activity score, DAS-28), function (health assessment questionnaire disability index, HAQ-DI) and structural joint damage (Ratingen erosion score). The baseline disease characteristics were compared using standard descriptive statistics. The effects of initial GC use on disease progression during follow-up were estimated using linear mixed models with random slope and random intercept, adjusted for potential confounders. In total, 592 patients with early disease were available, with 4.3 years of follow-up (average). Of these, 363 were initially treated with glucocorticoids (GC patients) and 228 were not (no-GC patients). DAS-28 (4.6 vs. 4.3, p = 0.01) and the HAQ-DI (0.94 vs. 0.82, p = 0.01) were higher at baseline in GC patients, while other prognostic factors were balanced at baseline. Neither the change of DAS-28, of HAQ-DI nor of the development of joint erosions differed between the two groups during follow-up. Escalation of treatment employing biologics was documented in 18.0% of the no-GC patients and 27.3% of the GC patients (p < 0.01). In this cohort, patients with early RA initially treated with GCs had higher measures of disease activity at baseline in comparison to no-GC patients. Despite a similar course of the disease in GC versus non-GC patients, the higher escalation rate to biologic agents in GC patients may reflect a disease less responsive to therapy in these patients. These data suggest that GC use as part of the initial therapeutic strategy in early RA may prevent a more severe course of the disease in patients with higher clinical disease measures at the start of therapy.

Rheumatoid arthritis treatment: the earlier the better to prevent joint damage

The management of rheumatoid arthritis has undergone major advances in recent years, both in terms of the drugs armamentarium and therapeutic strategy. Treating disease to target, aiming at remission, through a tight control protocol is regarded as the standard of care. Reaching clinical and radiographic disease remission has therefore become an achievable goal. Increasing evidence has demonstrated that early diagnosis, prompt treatment initiation and early achievement of remission are the major predictors of long-term clinical, functional and radiographic outcomes. Concentrating efforts in controlling disease activity in a very early window of opportunity offers unique sustained benefits. In this short review, we analysed the available evidence supporting the value of treating rheumatoid arthritis early and the impact on disease outcomes, with particular focus on radiographic progression.
