EULAR recommendations for the management and vaccination of people with rheumatic and musculoskeletal diseases in the context of SARS-CoV-2: the November 2021 update

The first EULAR provisional recommendations on the management of rheumatic and musculoskeletal diseases (RMDs) in the context of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), largely based on expert opinion, were published in June 2020. Since then, an unprecedented number of clinical studies have accrued in the literature. Several SARS-CoV-2 vaccines have been approved for population-wide vaccination programmes in EULAR-affiliated countries. Studies regarding vaccination of patients with (inflammatory) RMDs have released their first results or are underway.EULAR found it opportune to carefully review to what extent the initially consensus expert recommendations stood the test of time, by challenging them with the recently accumulated body of scientific evidence, and by incorporating evidence-based advice on SARS-CoV-2 vaccination. EULAR started a formal (first) update in January 2021, performed a systematic literature review according to EULAR's standard operating procedures and completed a set of updated overarching principles and recommendations in July 2021. Two points to consider were added in November 2021, because of recent developments pertaining to additional vaccination doses.

Anti-SSA/Ro positivity and congenital heart block: obstetric and foetal outcome in a cohort of anti-SSA/Ro positive pregnant patients with and without autoimmune diseases

OBJECTIVES

Neonatal lupus (NL) is an acquired disease caused by the transplacental passage of anti-SSA/Ro antibodies. The rate of congenital heart block (CHB), its most serious manifestation, ranges from 1 to 5%. The aim of this study was to retrospectively assess the prevalence of CHB in anti-SSA/Ro positive pregnant women with or without systemic autoimmune diseases from 2010 to 2020.

METHODS

Patients underwent monthly visit and a shared follow-up programme of weekly (16th-24th week) foetal heart rate assessment by obstetric ultrasound.

RESULTS

322 pregnancies in 258 anti-SSA/Ro patients were included; 314 were followed from the beginning of pregnancy because of the known presence of anti-SSA/Ro autoantibodies and 1 case of CHB occurred in an anti-SSA/Ro+ asymptomatic subject (0.3%). In the same period, 8 additional patients were referred to our clinics after in utero CHB diagnosis and subsequent discovery of anti-SSA/Ro without a disease diagnosis. Globally, 9 cases of congenital CHB (2.8%) occurred: 7 complete, 1 II-III degree and 1 rst degree CHB. Anti-SSB/La positivity was associated with a higher risk of CHB (7.8% vs. 1.2%; p=0.0071). No differences in maternal or foetal outcomes were found in comparison with a large cohort of unselected pregnancies except for caesarian section. Hydroxychloroquine (HCQ) was used in 58.3% pregnancies, with a different prevalence according with maternal diagnosis.

CONCLUSIONS

Our data suggest that anti-SSA/Ro positive patents with a de ned systemic autoimmune disease undergoing a strict follow-up since positive pregnancy test display a low risk of pregnancy complications, including but not limited to NL.

The Italian Society of Rheumatology clinical practice guidelines for the management of large vessel vasculitis

Objective: Since of the last publication of last recommendations on primary large-vessel vasculitis (LVV) endorsed by the Italian Society of Rheumatology (SIR) in 2012, new evidence emerged regarding the diagnosis and the treatment with conventional and biologic immunosuppressive drugs. The associated potential change of clinical care supported the need to update the original recommendations. Methods: Using the grading of recommendations assessment, development and evaluation (GRADE)-ADOLOPMENT framework, a systematic literature review was performed to update the evidence supporting the European Alliance of Associations for Rheumatology (EULAR) guidelines on LVV as reference. A multidisciplinary panel of 12 expert clinicians, a trained nurse, and a patients’ representative discussed the recommendation in cooperation with an Evidence Review Team. Sixty-one stakeholders were consulted to externally review and rate the recommendations. Results: Twelve recommendations were formulated. A suspected diagnosis of LVV should be confirmed by imaging or histology. In active GCA or TAK, the prompt commencement of high dose of oral glucocorticoids (40-60 mg prednisone-equivalent per day) is strongly recommended to induce clinical remission. In selected patients with GCA (e.g., refractory or relapsing disease or patients at risk of glucocorticoid related adverse effects) the use of an adjunctive therapy (tocilizumab or methotrexate) is recommended. In all patients diagnosed with TAK, adjunctive therapies, such as conventional synthetic or biological immunosuppressants, should be given in combination with glucocorticoids. Conclusions: The new set of SIR recommendations was formulated in order to provide a guidance on both diagnosis and treatment of patients suspected of or with a definite diagnosis of LVV.

Low frequency of disease flare in patients with rheumatic musculoskeletal diseases who received SARS-CoV-2 mRNA vaccine

BACKGROUND

Little is known about the safety of SARS-CoV-2 vaccination in patients with rheumatic musculoskeletal disease (RMD). We evaluated the occurrence of adverse events following immunization (AEFI) in RMD patients and heathy subjects who received anti-SARS-CoV-2 mRNA vaccine.

METHODS

We performed a telephone interview collecting any adverse event (AE) following immunization (AEFI) that occurred in RMD patients and healthy controls after the two doses of mRNA vaccine including common local reactogenicity and systemic events (for example, fever, fatigue/malaise, joint and muscle pain). We also investigated the onset of new signs or symptoms of the RMD after the vaccination.

RESULTS

We evaluated 126 patients with RMDs [105 females and 19 males, median age 51(IQR 17)] and 85 controls [62 females and 23 males, (median age 49 (20)]. Seventy patients (55.6%) were taking immunosuppressants, conventional synthetic (n=31, 43.3%) and/or biological [TNF inhibitors (n=49, 68.6%)], and 30 (23.8%) were taking hydroxychloroquine; treatment remained unchanged in 77% of patients. Eleven out of 126 patients and none of the 85 controls previously contracted COVID-19. The median follow-up from the completion of vaccination was 15 (3) weeks both in patients and controls. We reviewed 5 suspected cases confirming mild articular flares in 3 women (2.8) with inflammatory arthritis (2 psoriatic arthritis and 1 rheumatoid arthritis) while no disease reactivation was recorded in patients with connective tissue diseases; the incidence rate of RMD reactivation was 0.007 person/month. Multivariable logistic regression analysis showed similar frequencies of local and systemic AEFI in patients and controls with no effect of therapies or previous COVID-19. Local reaction-pain in the injection site-was the most frequently reported AEFI both in RMD and controls (71% and 75% of all the AEFI, respectively) after the first dose. Overall, up to 66% of patients experienced at least one AEFI at the second dose and up to 62% in the control group. Most of AEFI occurred within 2 days of vaccine administration. Two RMD patients developed pauci-symptomatic COVID-19 after the first dose of vaccine.

CONCLUSION

The low incidence rate of disease reactivation and the similar AEFI occurrence compared to controls should reassure on mRNA vaccine safety in RMD patients.

A novel mutation in collagen gene COL1A2 associated with transient regional osteoporosis

A young man was diagnosed with transient regional osteoporosis (TRO). The genetic analysis revealed a novel de novo likely pathogenic variant in COL1A2 gene. Our hypothesis is that TRO may be a possible clinical manifestation of osteogenesis imperfecta due to a reduced bone mass and an impaired trabecular mechanical competence.

INTRODUCTION

Transient regional osteoporosis (TRO) is a disease characterized by episodes of pain in the lower limbs involving the hip, knee, ankle or foot. Here, we present a clinical case of a Caucasian 25-year-old man exhibiting TRO. Based on few mild clinical findings suggestive of osteogenesis imperfecta (OI), but without a history of fragility fractures, we performed a genetic assessment to investigate this hypothesis.

METHODS

Medical history was obtained from the patient and family members, including biochemical, RMI and DXA assessments. Next-generation sequencing of COL1A1, COL1A2, COL2A1, CASR, CYP19A1, CUL7, CRTAP, KAL1, LEPRE1, LRP5, PPIB and SLC9A3R1, genes involved in juvenile osteoporosis, was performed.

RESULTS

We identified a novel de novo heterozygous missense variant, c.488G > A, in exon 11 of the COL1A2 gene (NM_000089.3), resulting in the putative p.Gly163Asp substitution in the N-terminal part of the helical domain of type I collagen. The variant was predicted to be damaging by the in silico prediction tools and the mutation was therefore classified as likely pathogenic. This mutation can affect skeletal health impairing bone mass and trabecular mechanical competence, inducing a disease whose features strictly evoke a TRO.

CONCLUSION

The present study describes a novel de novo heterozygous missense variant in COL1A2 gene, possibly inducing a propensity to trabecular microfractures. The recurrent symptomatic bone marrow oedema episodes could be the clinical picture consistent with the hypothesis of an inherited connective tissue disorder giving bone fragility.

Patient Perception of Depressive Symptoms in Rheumatic Diseases: A Cross-sectional Survey

OBJECTIVES

The presented study aimed to explore the presence and the self-identification of depressive symptoms among patients with rheumatic musculoskeletal diseases (RMDs) through the use of the Patient Health Questionnaire (PHQ-9).

METHODS

Between June and October 2019, patients from the regional association for people with RMDs in Lombardy, Italy (ALOMAR), were invited to participate in a cross-sectional online survey. Participants completed PHQ-9 along with a survey about their perception of depressive symptoms. Patients were stratified according to PHQ-9 score as follows: not depressed (<4), subclinical or mild depression (5-9), moderate depression (10-14), moderately severe depression (10-14), and severe depression (20-27). Descriptive statistics and analyses of variance were used to explore data.

RESULTS

Of the 192 RMD patients who completed PHQ-9, 35 (18.2%) were not depressed, 68 (35.4%) had subclinical or mild depression, 42 (21.9%) had moderate depression, 30 (15.6%) had moderately severe depression, and 17 (8.9%) had severe depression. Contrary to the above findings, only 16 respondents (8.3%) reported that they experienced depressive symptoms, and only 7 of the 16 were being followed by a psychiatrist. Respondents with higher PHQ-9 scores tended to have concomitant fibromyalgia, to be younger, and to be overweight.

CONCLUSIONS

The current results indicate the overall burden of depressive symptoms in RMD patients. While clinical depression (PHQ-9 >10) was detected in 41.2% of respondents, only 8.3% reported that they experience depressive symptoms. Routine screening of RMD patients for depression is therefore critical.

Determinants of Diagnostic Delay in Complex Regional Pain Syndrome Type 1: An Observational Study of 180 Consecutive New Cases

BACKGROUND/OBJECTIVE

Complex regional pain syndrome type 1 (CRPS-1) is a disabling painful disease, with variable outcomes in terms of chronic pain and disability. A long time between onset and diagnosis seems predictive for late recovery and progression toward a chronic disease. This study aims to investigate demographic and clinical variables associated with delayed CRPS-1 diagnosis.

METHODS

From March 2013 to January 2018, consecutive patients newly diagnosed according to International Association for the Study of Pain diagnostic criteria for CRPS-1 were recruited. Demographic and clinical variables were collected at diagnosis. Student t test and Mann-Whitney U test were used for comparisons; Cox proportional hazards model was applied to evaluate the variables associated with delayed CRPS-1 diagnosis.

RESULTS

One hundred eighty patients entered the study. At diagnosis, women were older, and foot was more often involved than hand. The triggering event was more commonly a trauma without fracture for foot disease and a fracture for hand localization. No differences between hand and foot disease were found by the International Association for the Study of Pain diagnostic categories (clinical vs research) or pain measures. Variables significantly associated with a longer time between disease onset and diagnosis were foot localization, general practitioner referral, higher number of visits before CRPS diagnosis, and prior physiotherapy prescribed for symptoms later diagnosed as CRPS. An overt clinical manifestation (research CRPS-1) predicted a shorter delay.

CONCLUSIONS

Foot localization, prior physiotherapy prescribed for symptoms later diagnosed as CRPS, and a disease without overt clinical manifestations were independent predictive factors for a delayed diagnosis. Clinicians should pay attention to these issues to ensure a timely diagnosis and possibly avoid progression toward a chronic disease.

Myocardial involvement in anti-phospholipid syndrome: Beyond acute myocardial infarction

Anti-phospholipid antibodies (aPL) are the serological biomarkers of anti-phospholipid syndrome (APS), an autoimmune disorder characterized by vascular events and/or pregnancy morbidity. APS is a unique condition as thrombosis might occur in arterial, venous or capillary circulations. The heart provides a frequent target for circulating aPL, leading to a wide variety of clinical manifestations. The most common cardiac presentation in APS, valvular involvement, acknowledges a dual etiology comprising both microthrombotic and inflammatory mechanisms. We describe the cases of 4 patients with primary APS who presented a clinically manifest myocardiopathy without epicardial macrovascular distribution. We propose that microthrombotic/inflammatory myocardiopathy might be an overlooked complication of high-risk APS. As extensively hereby reviewed, the literature provides support to this hypothesis in terms of anecdotal case-reports, in some cases with myocardial bioptic specimens. In aPL-positive subjects, microthrombotic/inflammatory myocardial involvement might also clinically manifest as dilated cardiomyopathy, a clinical entity characterized by ventricular dilation and reduced cardiac output. Furthermore, microthrombotic/inflammatory myocardial involvement might be subclinical, presenting as diastolic dysfunction. Currently, there is no single clinical or imaging finding to firmly confirm the diagnosis; an integrated approach including clinical history, clinical assessment, laboratory tests and cardiac magnetic resonance should be pursued in patients with suggestive clinical presentation.

Tumor induced osteomalacia: A single center experience on 17 patients

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome due to a phosphaturic tumor, which overproduces Fibroblast Growth Factor 23 (FGF-23), causing hyperphosphaturia, hypophosphatemia, low 1,25(OH)₂D and osteomalacia. Tumor localization is critical, diagnostic delay ranges from 2.5 to 28 years and to date surgical removal is considered effective treatment. We retrospectively evaluated patients with definite diagnosis of TIO referred to a tertiary Rheumatology Center between September 2000 and May 2020, investigating clinical management and disease outcome. We included 17 patients: 10 (58.8%) were females, mean age at diagnosis was 55.3 ± 13.9 years (mean ± standard deviation), with a diagnostic delay from symptoms onset to tumor detection of 6.6 ± 6.25 years. Biochemical data were: serum phosphorus 1.3 ± 0.4 mg/dL (Reference Range: 2.5-4.6), serum 1,25(OH)₂D 31.8 ± 22.9 ng/mL (RR: 25-86), intact FGF-23, 358.9 ± 677 pg/mL (RR: 25-45); 24 h-Urine Phosphorus was increased in only 2 patients, while tubular reabsorption of phosphate (TRP) was decreased in all patients confirming a renal phosphate wasting. In 2013 ⁶⁸Ga- DOTA-based PET/CT was introduced in routinely practice and diagnostic delay was consistently reduced (from 8.6 ± 7.9 to 4.3 ± 2.4 years). Thirteen patients underwent surgery, one patient underwent radiofrequency ablation; 3 patients, not eligible for surgery, were treated only with supplements of phosphorus and calcitriol. One was started on Burosumab after several unsuccessful surgical attempts. After surgery or ablation, 8 patients had complete remission, 3 TIO persistence, and 3 had overtime relapse. Relapses were observed only in patients who previously underwent closed biopsy. To our knowledge, this is the widest European cohort of TIO patients in the last two decades. We confirm a usual diagnostic delay and recommend a stepwise diagnostic approach. Tumor biopsy is not recommended due to the potential cell spilling. Surgery is generally considered a definitive treatment, even though other approaches have been successful in curing TIO. Active surveillance on possible recurrence is always needed. Burosumab appears a promising therapy.

Predictors, Risk Factors, and Incidence Rates of Psoriatic Arthritis Development in Psoriasis Patients: A Systematic Literature Review and Meta-Analysis

Background

Agreement on how to identify psoriasis (PsO) patients at risk of developing psoriatic arthritis (PsA) is lacking.

Objective

To identify predictors, risk factors and incidence rate (IR) of PsA development in PsO patients through a systematic literature review (SLR) and meta-analyses (MA).

Methods

MEDLINE, Embase, and Cochrane databases were searched. Cohort studies were used to assess the predictors, while case–control studies for PsA risk factor determination.

Results

We screened 4698 articles for eligibility, and 110 underwent a full reading and 26 were finally included. Among skin and nail phenotypes, PsO severity and nail pitting were selected as predictors of PsA development. Furthermore, PsO patients with arthralgia (pooled RR 2.15 [1.16; 3.99]) and/or with imaging-MSK inflammation (pooled RR 3.72 [2.12; 6.51]) were at high risk of PsA. Higher categories of BMI and a family history of PsA were other predictors. In outpatient-based cohort studies, the IR of PsA per 100 patient-years varied from 1.34 to 17.4.

Limitations

Despite the strength of the overall results, the heterogeneity and the number of the cohort studies could be considered a limitation.

Conclusions

This study provides a tentative profile of the PsO patient at risk of PsA and will help the design of PsA prevention trials.

The role of extracellular vesicles in rheumatoid arthritis: a systematic review

Rheumatoid arthritis (RA) is a chronic inflammatory disease that carries high social and economic costs and can lead to permanent disability. RA pathogenesis has not been completely elucidated yet. Extracellular vesicles (EVs) are membrane-contained vesicles released by cells playing a role in cell-to-cell communication and they could be involved in different diseases. Evidence on the involvement of EVs in RA is currently inconclusive. Therefore, a systematic review on the role of EVs in RA was performed in order to explore this relationship. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The research was conducted on PubMed, Scopus, and Embase up to March 5, 2020: 41 studies were analyzed out of 674 screened. The total plasmatic and synovial fluid (SF) EV number seems increased in RA as compared with healthy controls. Both RA plasma and SF contained EVs subpopulations of heterogenous origin, especially derived from platelets and immune system cells. No univocal evidence emerged on miRNA expression and EV content profile within RA patients. EVs showed to enhance pro-inflammatory pathways, such as cytokines and chemokine release and TNF blockade seemed to revert this effect. Our work highlights the requirement to standardize study methodologies in order to make results comparable and draw conclusions that remain, at present, unclear.

Decreasing severity of Paget's disease of bone in northern Italy over the last two decades: results of a monocentric study on 391 patients

Patients with Paget's disease of bone recruited over the last 20 years by a single centre were evaluated to find possible clinical changes. All markers of severity showed consistent downward trends. A reduced disease incidence could seemingly refer to lower sensitivity of the diagnostic tools owing to lower severity.

INTRODUCTION

This study aimed to evaluate if the severity of Paget's disease of bone (PDB) is decreasing and whether a milder phenotype can have affected the results of studies on disease prevalence.

METHODS

From August 2007 to August 2019, 167 patients with PDB were referred to our centre. Demographic and clinical characteristics were collected and compared with those of a sample of 224 patients enrolled in the same setting between January 2000 and July 2007. Multivariate analyses on 391 patients as a whole were performed assuming the year of presentation as explanatory variable.

RESULTS

Patients of newer sample were diagnosed at a significantly older age (64.0 ± 11.3 vs 61.1 ± 11.6; p = 0.01). By comparing clinical features acknowledged as markers of disease severity, the mean number of involved bones, the proportion of skeletal involvement, and pre-treatment serum alkaline phosphatase (SAP) values all showed significant decreases (p < 0.001) in the more recent sample. Multivariate analyses confirmed these results for the latter two indices. Further markers of disease severity such as the prevalence of monostotic disease and normal SAP at diagnosis showed the same trend. The sensitivity of tools allowing incidental diagnosis in asymptomatic patients showed a reduced sensitivity: -11% for radiological assessments and -33% for SAP.

CONCLUSIONS

Allowing for referral differences, our study provides information on reduced severity of PDB over the last two decades. A milder phenotype affects the age at onset and impairs the sensitivity of the diagnostic tools contributing to reduce the prevalence of PDB patients incidentally discovered.

Treatment journey in rheumatoid arthritis with biosimilars: from better access to good disease control through cost savings and prevention of nocebo effects

Early diagnosis and treatment of rheumatoid arthritis (RA) are of critical importance to halt the progression of the disease. Optimal use of advanced imaging techniques or biomarkers may facilitate early diagnosis of RA. Even though many disease-modifying anti-rheumatic drugs (DMARDs) are available for RA treatment, biological DMARDs (bDMARDs) offer expanding therapeutic options and good outcomes in patients with RA who do not have a sufficient response to conventional synthetic DMARDs. However, high costs of bDMARDs have limited patient access to optimised disease management and increased the cost burden for healthcare systems. The advent of biosimilars led to significant cost savings driven by price competition among the reference products, which could be beneficial for healthcare systems. Healthcare provider (HCP)–patient communication and informed shared decision-making are crucial to prevent the occurrence of a nocebo effect, which results from negative perceptions that patients may have and could lead to less effective outcomes. Research has demonstrated that effective communication between HCPs and patients utilising positive framing can improve acceptance by patients to be initiated on or switched to a biosimilar and can help to integrate biosimilars into routine clinical practice to maximise benefits for patients with RA.

The Crucial Questions on Synovial Biopsy: When, Why, Who, What, Where, and How?

In the majority of joint diseases, changes in the organization of the synovial architecture appear early. Synovial tissue analysis might provide useful information for the diagnosis, especially in atypical and rare joint disorders, and might have a value in case of undifferentiated inflammatory arthritis, by improving disease classification. After patient selection, it is crucial to address the dialogue between the clinician and the pathologist for adequately handling the sample, allowing identifying histological patterns depending on the clinical suspicion. Moreover, synovial tissue analysis gives insight into disease progression helping patient stratification, by working as an actionable and mechanistic biomarker. Finally, it contributes to an understanding of joint disease pathogenesis holding promise for identifying new synovial biomarkers and developing new therapeutic strategies. All of the indications mentioned above are not so far from being investigated in everyday clinical practice in tertiary referral hospitals, thanks to the great feasibility and safety of old and more recent techniques such as ultrasound-guided needle biopsy and needle arthroscopy. Thus, even in rheumatology clinical practice, pathobiology might be a key component in the management and treatment decision-making process. This review aims to examine some essential and crucial points regarding why, when, where, and how to perform a synovial biopsy in clinical practice and research settings and what information you might expect after a proper patient selection.

Clinical and peculiar immunological manifestations of SARS-CoV-2 infection in systemic lupus erythematosus patients

Objectives

The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in patients with systemic lupus erythematosus (SLE) remains unclear and data on clinical manifestations after infection are lacking. The aim of this multicentre study is to describe the effect of SARS-CoV-2 in SLE patients.

Methods

SLE patients referring to 4 Italian centres were monitored between February 2020 and March 2021. All patients with SARS-CoV-2 infection were included. Disease characteristics, treatment, disease activity, and SARS-CoV-2 related symptoms were recorded before and after the infection.

Results

Fifty-one (6.14%) SLE patients were included among 830 regularly followed-up. Nine (17.6%) had an asymptomatic infection. Five (9.8%), out of 42 (82.6%) symptomatic, developed interstitial pneumonia (no identified risk factor). The presence of SLE major organ involvement (particularly renal involvement) was associated with asymptomatic SARS-CoV-2 infection (p-value = 0.02). Chronic corticosteroid therapy was found to be associated with asymptomatic infection (p-value = 0.018). Three SLE flares (5.9%) were developed after SARS-CoV-2 infection: one of them was characterized by MPO-ANCA positive pauci-immune crescentic necrotizing glomerulonephritis and granulomatous pneumonia.

Conclusions

SARS-CoV-2 infection determined autoimmune flares in a small number of our patients. Our data seem to confirm that there was not an increased risk of SARS-CoV-2 in SLE. Patients with asymptomatic SARS-CoV-2 infections were those having major SLE organ involvement. This may be explained by the high doses of corticosteroids and immunosuppressive agents used for SLE treatment.

COVID-19 related poor mental health and sleep disorders in rheumatic patients: a citizen science project

BACKGROUND

Patients with chronic rheumatic diseases (RDs) are more vulnerable and the containment measures related to the COVID-19 pandemic might have severe psychological consequences. We investigated the presence of and risk factors associated with poor mental health, sleep disorders among RDs during the pandemic.

METHODS

This cross-sectional Italian citizen science project evaluated the psychological impact of the COVID-19 pandemic in patients with RDs. Between May and September 2020, eleven RD patients' associations sent the survey by using their mailing list and the related webpage and social network. 507 RD patients completed an ad-hoc anonymous online survey including the Perceived Stress Scale (PSS) and Impact Event Scale-Revised (IES-R).

RESULTS

The mean scores on the PSS-10 and the IES-R were 18.1 and 29.7, respectively. Higher PSS scores were associated with younger age (p <  0.01), female gender (p <  0.01), overweight/obesity (p = 0.01), psychiatric pharmacotherapy (p <  0.01), and anxiety for loss of income (p <  0.01). Higher IES-R scores were associated with female gender (p <  0.01), intestinal diseases (p = 0.03), anxiety (p <  0.01), and health concern (p <  0.01). Among 375 patients with inflammatory arthritis, 246 (65.6%) had trouble staying asleep, 238 (63.5%) falling asleep, and 112 (29.9%) had dreams about the pandemic. Older age (OR = 1.038, CI 1.002-1.076), psychiatric pharmacotherapy (OR = 25.819, CI 11.465-58.143), and COVID infection (OR = 2.783, CI 1.215-6.372) were predictive of insomnia during the pandemic.

CONCLUSIONS

A considerable COVID-19 related psychosocial burden has been detected in RDs. Different factors were predictive of poor mental health and sleep disorders in these patients. Focused supportive strategies should be implemented to improve the psychological well-being of fragile patients during pandemics.

Tofacitinib: Real-World Data and Treatment Persistence in Rheumatoid Arthritis

Tofacitinib is an oral Janus kinase (JAK) inhibitor indicated for the treatment of rheumatoid arthritis (RA). The efficacy and safety/tolerability of tofacitinib have been extensively evaluated as monotherapy and combination therapy in multiple, randomised, multicentre studies in patients with RA. Tofacitinib as monotherapy (as first- and second-line treatment) or as combination with methotrexate (MTX) or other csDMARDs as second- and third-line treatment is effective and generally well tolerated in patients with RA. This article focuses on recent real-world evidence investigating the effectiveness, treatment persistence and safety/tolerability of tofacitinib in patients with RA. With this purpose, a literature review was conducted from April 2018 up to October 2020 for the effectiveness, persistence and safety of tofacitinib for the treatment of RA, primarily focusing on real-world studies. These retrospective and prospective and observational studies demonstrate the effectiveness of tofacitinib, thus supporting pivotal data from the clinical trial programme. Treatment persistence was generally comparable to that of biologic disease-modifying anti-rheumatic drugs. Safety findings in these observational studies were consistent with the known safety profile of the approved dose of 5 mg twice daily.

A case report of monoarthritis in a COVID-19 patient and literature review: Simple actions for complex times

RATIONALE

COVID-19 presentation is multifaceted and up to 44% of patients affected by COVID-19 experience musculoskeletal complaints, mostly in the form of diffuse aspecific arthromyalgias. Nevertheless, only a few cases of arthritis following SARS-CoV2 infection are reported.

PATIENT CONCERNS

A 27-year-old man affected by nail psoriasis presented with monoarthritis 2 weeks after being diagnosed with COVID-19.

DIAGNOSES

Diagnostic work-up and differential diagnosis were made difficult by patient isolation, absence of lab tests, and his visit via telemedicine, even though signs of first metacarpophalangeal joint involvement were clear.

INTERVENTIONS

Due to the inefficacy of acetaminophen and nonsteroidal anti-inflammatory drugs, the patient was prescribed oral steroids with a rapid benefit.

OUTCOMES

The patient's response to oral steroid was prompt and maintained even after therapy tapering. Even so, a formal diagnosis was not possible due to a difficult diagnostic work-up and lack of a long-term follow-up.

LESSONS

Like many other viral diseases, SARS-CoV2 can play as a causative agent or as a trigger for inflammatory arthritis development in predisposed individuals.

Does methotrexate influence COVID-19 infection? Case series and mechanistic data

Background

To investigate whether methotrexate treatment may affect the susceptibility to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Methods

Clinical assessment of symptoms, SARS-CoV-2 RNA, and anti-SARS-CoV-2 IgG in an initial case series of four families and confirmatory case series of seven families, within which one family member developed coronavirus disease 19 (COVID-19) and exposed another family member receiving methotrexate treatment; experimental part with methotrexate treatment of mice and organoids followed by the assessment of mRNA and protein expression of the SARS-CoV-2 receptor angiotensin-converting enzyme (ACE)-2.

Results

In the initial case series, three of four women on a joint ski trip developed COVID-19, while the fourth woman, under treatment with methotrexate, remained virus-free. Two of the three diseased women infected their husbands, while the third husband treated with methotrexate remained virus-free. In addition, 7 other families were identified in a follow-up case series, in which one member developed COVID-19, while the other, receiving methotrexate, remained healthy. Experimentally, when mice were treated with methotrexate, ACE2 expression significantly decreased in the lung, in the intestinal epithelium, and in intestinal organoids.

Conclusion

These clinical and experimental data indicate that methotrexate has certain protective effects on SARS-CoV-2 infection via downregulating ACE2.

POS1178 THE ROLE OF VIRTUAL TELEPHONE VISITS IN THE TIGHT CONTROL OF RHEUMATOID ARTHRITIS PATIENTS TREATED WITH TARGETED THERAPIES DURING THE COVID-19 PANDEMIC

Background:

Rheumatic patients’ follow-up in terms of treatment adherence, disease control achieved with treat-to-target (T2T) and tight-control strategy have been deeply influenced by nationwide mitigation strategies such as quarantine, travel restrictions, and inadequate access to routine visits, laboratory and imaging investigations. These restrictions could be potentially detrimental for patients’ care, but to what extent these measures affected the T2T and tight-control approach in rheumatoid arthritis (RA) is unknown.

Objectives:

This study investigated whether the adoption of telephone virtual care imposed by COVID-19 pandemic has been effective in maintaining remission in RA treated with targeted therapies and to identify factors associated with its maintenance.

Methods:

This observational retrospective real-life study was conducted from November 2019 through September 2020. Clinical Disease Activity Index (CDAI) of RA patients treated with targeted therapies was analysed retrospectively before, during and after the national lockdown (LD). During LD period, rheumatologists provided virtual care by telephone to assess the clinical status to guarantee the absence of current contraindications to therapy. Then, patients could choose whether to receive home drug delivery or to maintain their face-to-face consultations. Logistic mixed effects regression models were fitted, with CDAI remission as response variable. A multivariate analysis and a parsimonious model were finally obtained by stepwise selection procedure using AIC.

Results:

Data were extracted from a longitudinal observational registry, and at baseline, 502 RA patients were eligible for this study. 52 patients failed to complete their follow-up, 450 patients were included in the final analysis. During LD, 359 patients chose in-person visit, 91 patients home drug delivery and virtual visit. Our cohort did not show a statistically significant decrease in the number of patients fulfilling CDAI remission criteria all along the three periods. Among the 450 patients evaluated, the CDAI remission rate was 40.22% (N=181) and 43.78% (N=197) during pre-LD and post-LD, respectively. As for the 359 patients who choose in-person visits during LD, 43.18% (N=155) were in remission according to CDAI. The final model (step-wise selection) applied to the multivariate analysis of factors that potentially could interfere with disease control in patients with CDAI remission showed that the probability to maintain remission was associated with Caucasian ethnicity, male gender and absence of fibromyalgia (Table 1 below).

Conclusion:

Telephone-based tight control strategy ensured satisfactory management of RA treated with targeted therapies during the first wave of COVID-19 pandemic. All along the three periods, we observed that the probability to be in CDAI remission was significantly associated with Caucasian ethnicity, male gender, and absence of fibromyalgia. This temporary approach has been a feasible compensation for face-to-face visits, thus reassuring for future months before the end of pandemic.

POS0145 PREDICTORS OF PSORIATIC ARTHRITIS DEVELOPMENT IN PSORIASIS PATIENTS: A SYSTEMATIC LITERATURE REVIEW AND META-ANALYSIS

Background:

Up to 30% of Psoriasis (PsO) patients are prone to develop Psoriatic Arthritis (PsA). Agreement on how to identify PsO patients at risk of developing PsA is still lacking (1).

Objectives:

To identify predictors of PsA development in PsO patients through a systematic literature review (SLR) and meta-analyses (MA).

Methods:

MEDLINE, EMBASE and COCHRANE databases were searched (up to February 22nd, 2020). The PICO framework (population = PsO patients; intervention = clinical, environmental, imaging and genetic features; comparator = not applicable; outcome = PsA development) was used to design searches and define the eligibility of studies for inclusion. The MA focuses on 3 major features as possible predictors: i) PsO skin and nail involvement; ii) musculoskeletal (MSK) complaints; iii) inflammation and structural damage detected by imaging (Table 1). The sample estimates of the relative risk were pooled only when the studies were homogeneous in terms of cohort of patients, follow-up, study design and metrics.

Results:

4698 articles were screened for eligibility, 110 underwent a full reading and 29 were finally included. Figure 1 shows the study flow-chart for article selection. Though pooling was judge not appropriate, 5/7 prospective studies significantly support a predictive value of PsA development in patients with severe PsO (n=174635). While the predictive value of nail involvement is not well defined (n=2202), the pooled estimate from two cohort studies (n=474) supports nail pitting as predictor of PsA (RR=2.14 [1.32; 3.46]). Moving to the MSK complaints, the risk of developing PsA is about two times greater in PsO with than without arthralgia (pooled RR: 2.15 [1.16, 3.99]) within 2 years. Lastly, PsO patients with inflammation or structural damage detected by imaging are nearly four times more likely to develop PsA within 1-2 years (pooled RR from 4 cohort studies (n=247): 3.72 [2.12; 6.51]) (Table 1). The incidence rate of PsA varies from 1.34 to 5.9/100 p-ys in PsO and from 10.9 to 12.5/100 p-ys in PsOAr.

Conclusion:

Arthralgia and inflammation and/or structural damage detected by imaging are predictive features, likely prodromal, of PsA development. PsO severity and nail pitting are clinical manifestations related to PsA development.
