Effectiveness and safety profile of tofacitinib and baricitinib in rheumatoid arthritis patients: results from a 24-month real-life prospective study in Southern-Italy

The primary objectives of the study were to evaluate the efficacy and safety of tofacitinib and baricitinib up to 24 months of follow-up in patients with rheumatoid arthritis (RA) treated in Southern Italy. Patients' data, activity index, and clinimetric scores were collected at baseline (T0), six (T6), twelve (T12), and twenty-four (T24) months following treatment initiation. At six, twelve, and twenty-four months, adverse events and treatment cessation were also recorded. Sixty-eight patients (mean age: 62.2±10.9 years; mean RA duration: 15±9.6 years) were enrolled over a period of 12 weeks. At baseline, twenty-four patients (35.3%) were treated with tofacitinib, and forty-four patients (64.7%) were treated with baricitinib. The baseline mean disease activity was moderate as measured by DAS28- ESR (5.0±1.0), DAS 28 CRP (4.69±0.94), and SDAI (26.87±10.73) score. Before beginning JAKinhibs therapy, thirty-two patients (61.8%) were taking bDMARDs, while the remaining thirty-six (38.2%) were bDMARDs-naïve. The 24-month retention rate for JAKinhibs was 91.1%. Six months after beginning treatment with JAKinhibs, a statistically significant improvement was observed in all evaluated activity indices and clinimetric scores. Improvement was confirmed during the 12- and 24-month follow-up evaluations. The positive correlation between baseline-T6 SDAI delta and discontinuation of JAKinhibs (p=0.02) suggests that RA worsening in the first six months may be a predictor of therapy withdrawal. Patients with RA responded favorably to tofacitinib and baricitinib in this prospective, real-world study from a single center in Southern Italy. Efficacy was observed despite an underlying persistent and treatment-resistant disease.

POS1267 LONG-TERM SURVEY STUDY OF THE IMPACT OF COVID-19 ON SYSTEMIC AUTOIMMUNE DISEASES. LOW DEATH RATE DESPITE THE INCREASED PREVALENCE OF SYMPTOMATIC INFECTION. ROLE OF PRE-EXISTING INTERSTITIAL LUNG DISEASE AND ONGOING TREATMENTS

Background

Patients with autoimmune systemic diseases (ASDs) can be counted among frail populations as regards the predisposition to COVID-19 due to the frequent visceral organ involvement and comorbidities, as well as the ongoing immunomodulating treatments.

Objectives

Our long-term multicenter telephone survey prospectively investigated the prevalence, prognostic factors, and outcomes of COVID-19 in Italian ASD patients during the first 3 pandemic waves.

Methods

A large series of 3,918 ASD patients (815 M, 3103 F; mean age 59±12SD years) was consecutively recruited at the 36 referral centers of COVID-19 & ASD Italian Study Group. In particular, ASD series encompassed the following conditions: rheumatoid arthritis (n: 981), psoriatic arthritis (n: 471), ankylosing spondylitis (n: 159), systemic sclerosis (n: 1,738), systemic lupus (172), systemic vasculitis (n: 219), and a miscellany of other ASDs (n: 178). The development of COVID-19 was recorded by means of telephone survey using standardized symptom-assessment questionnaire (1).

Results

A significantly increased prevalence of COVID-19 (8.37% vs 6.49%; p<0.0001) was observed in our ASD patients, while the cumulative death rate revealed statistically comparable to the Italian general population (3.65% vs 2.95%; p: ns). In particular, among the 328 ASD patients complicated by COVID-19, 57 (17%) needed hospitalization, while mild-moderate manifestations were observed in the large majority of individuals (83%). In addition, 12/57 hospitalized patients died due to severe interstitial pneumonia and/or cardiovascular manifestations.

Interestingly, a significantly higher COVID-19-related death rate was observed in systemic sclerosis patients compared to the Italian general population (6.29% vs 2.95%; p=0.018). Other adverse prognostic factors to develop COVID-19 were the patients’ older age, male gender, pre-existing ASD-related interstitial lung involvement, and chronic steroid treatment. Conversely, patients treated with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) showed a significantly lower prevalence of COVID-19 compared to those without (3.58% vs 46.99%; p=0.000), as well as the chronic administration of low dose aspirin in a subgroup of SSc patients (with 5.57% vs without 27.84%; p=0.000).

Conclusion

The cumulative impact of COVID-19 on ASD patients after the first 3 pandemic waves revealed less severe than that observed during the first phase of pandemic (1), especially with regards to the death rate that was comparable to the Italian general population in spite of the increased prevalence of complicating COVID-19 in the same ASD series.

Ongoing long-term treatments, mainly csDMARDs, might usefully contribute to generally positive outcomes of in this frail patients’ population.

Of note, a significantly increased COVID-19-related mortality was recorded in only SSc patients’ subgroup, possibly favored by pre-existing lung fibrosis. Among different ASD, SSc deserves special attention, since it shares the main pathological alterations with COVID-19, namely the interstitial lung involvement and the endothelial injury responsible for diffuse microangiopathy.

Besides SSc, the patients’ subgroups characterized by older age, chronic steroid treatment, pre-existing interstitial lung disease, and/or impaired COVID-19 vaccine response (1-3), may deserve well-designed prevention and management strategies.

POS1337 ADULT-ONSET STILL’S DISEASE WITH ELDERLY ONSET, RESULTS FROM A MULTICENTRE STUDY AND ASSESSMENT OF AGE INFLUENCE ON CLINICAL FEATURES AND DISEASE OUTCOMES

Background

Aging is a physiological, multidimensional, and irreversible process, occurring in humans over time. Interestingly, multiple lines of evidence have recently suggested that some diseases, generally affecting young adults, are nowadays described in the elderly, although possibly associated with different symptoms or complications. In this context, a possible occurrence of adult onset Still’s disease (AOSD) in elderly has been suggested. This is a rare inflammatory disorder of unknown origin usually observed in young adults [1-3].

Objectives

In this study, we aimed at describing the clinical characteristics, life-threatening complications occurrence, and mortality of AOSD patients with an elderly onset. The manifestations of these patients were also compared with those with a younger onset. Furthermore, the predictive role of age was evaluated on clinical features and disease outcomes. Finally, in these patients, an assessment of associated comorbidities was also performed.

Methods

A retrospective assessment of prospectively followed patients, from January 2001 to April 2021, was provided to analyse clinical features, life-threatening complications occurrence, and mortality in AOSD patients with onset in elderly. AOSD patients, who were included in multicentre Gruppo Italiano di Ricerca in Reumatologia Clinica e Sperimentale (GIRRCS) cohort, were evaluated.

Results

Out of 221 assessed patients, 37 (16.7%) had an onset of the disease aged over than 60 years. When compared with younger patients, these were characterised by a higher prevalence of pericarditis (p=0.008), comorbidities (p<0.0001), and mortality (p=0.023).

Additionally, our analysis showed that pleuritis and pericarditis positively correlated with age (coefficient=0.227, p=0.001; coefficient=0.213, p=0.001, respectively). Furthermore, the occurrence of parenchymal lung disease was significantly related with age (coefficient=0.168, p=0.012). The presence of comorbidities positively correlated with age (coefficient=0.443, p<0.0001). Moreover, age was negatively related to the polycyclic pattern (coefficient=-0.209, p=0.002). A correlation between mortality and age was also retrieved (coefficient=0.158, p=0.019).

Age predicted the presence of serositis in both univariate (HR: 1.02, 95%CI: 1.01-1.03, p=0.007) and multivariate analyses (HR: 1.02, 95%CI: 1.01-1.04, p=0.007). Age was also a significant predictor of parenchymal lung disease in both univariate (HR: 1.03, 95%CI: 1.01-1.05, p=0.017) and multivariate analyses (HR: 1.03, 95%CI: 1.00-1.05, p=0.048). No significant results were observed assessing the predictive role of age on occurrence of macrophage activation syndrome. Furthermore, age resulted to be a negative predictor of polycyclic pattern only in univariate analysis (HR: 0.99, 95%CI: 0.97-1.00, p=0.048). Finally, age significantly predicted the mortality in both univariate (HR: 1.03, 95%CI: 1.00-1.06, p=0.034) and multivariate analyses (HR: 1.05, 95%CI: 1.01-1.08, p=0.012).

Conclusion

Clinical features of AOSD patients with elderly onset were described in our multicentre cohort. Although the main clinical characteristics were similar comparing older and younger patients, patients aged over 60 years at disease onset were characterised by an increased prevalence of serositis, comorbidities, mostly cardiometabolic, and a higher mortality rate. Age predicted the presence of parenchymal lung disease and mortality, and it could be considered a further negative prognostic factor in AOSD.

Micronutrients deficiencies in patients with spondylarthritis: the potential immunometabolic crosstalk in disease phenotype

OBJECTIVE

Micronutrient deficiencies (MNDs) are common among patients with certain chronic inflammatory diseases. They are associated with a pro-inflammatory status and co-morbidities. However, no studies have specifically investigated MNDs in Spondyloarthritis (SpA). This paper aimed at analyzing the occurrence of anemia and deficiencies of ferritin (Fe), vitamin D [25(OH)D], vitamin B12 (B12), and folic acid (FA) in SpA patients. The interplay of MNDs with age, gender, and metabolic abnormalities was also explored.

PATIENTS AND METHODS

MNDs were evaluated in 220 SpA outpatients (137 females and 83 age-matched males) with psoriatic arthritis (PsA, n=110) and non-psoriatic SpA (n=110). Metabolic parameters were analyzed. Disease activity was assessed by either Disease Activity in PSoriatic Arthritis (DAPSA) or Ankylosing Spondylitis Disease Activity Score with C-Reactive Protein (ASDAS-CRP) as appropriate, while the functional status was evaluated using Health Assessment Questionnaire modified for SpA (HAQ-S).

RESULTS

Anemia occurred in 13.6% of subjects of the study cohort and almost wholly in females (p=0.004). Females showed higher Fe deficiency (p=0.04) and lower Fe levels (p=0.0003) than males. Hemoglobin (Hb) resulted inversely related to age and CRP (p=0.01 and p=0.008) in male group. The 25(OH)D deficiency (≤20 ng/ml) was present in 23.2% of the cohort with a higher prevalence in males than females (p=0.02): moreover, 25(OH)D inversely correlated with disease duration (p=0.02) in males. The B12 deficiency (≤200 pmol/l) was rare (13.2%), while FA ≤4 ng/ml was frequent (22%) and associated with B12 deficiency in 31% of cases. SpA patients in moderate/high disease activity had higher Body Mass Index (BMI) (p=0.04) and HAQ-S (p<0.0001), as well as lower Hb (p=0.02), and Fe (p=0.03) than patients in remission/low disease activity (LDA). In patients with extra-articular manifestations, female sex was prevalent (F:M=2) and B12 levels were lower than in patients without (p=0.005). Interestingly, 25(OH)D was lower (p=0.04) and both BMI and HAQ-S (p=0.036 and p=0.01) were higher in patients without extra-articular involvement than patients with.

CONCLUSIONS

Our findings documented a relevant prevalence of MNDs in SpA patients, and its strict interplay with gender and metabolic abnormalities by highlighting the role of MNDs in inflammatory-dependent dysmetabolism in SpA.

AB0515 MICRONUTRIENT DEFICIENCIES IN PATIENTS WITH SPONDYLOARTHRITIS: AGE AND GENDER IMPLICATIONS

Background:

Micronutrient deficiencies (MNDs) are common among patients with chronic inflammatory diseases. These are associated with a pro-inflammatory status and co-morbidities, and influenced by several factors, such as age and gender.

Objectives:

No any study has investigated MNDs and their correlation with gender in Spondyloarthritis (SpA). With this purpose, this study analyzed the occurrence of anemia and the status of ferritin (Fe), vitamin D [25(OH)D], vitamin B12 (B12), and folic acid (FA) in a cohort of patients with SpA.

Methods:

Levels of Hb, Fe, 25(OH)D, B12, FA, were evaluated in 220 SpA outpatients (137 females and 83 age-matched males) with Psoriatic arthritis (PsA, n=110) and SpA (n=110). Disease activity was assessed by DAPSA or ASDAS-CRP as appropriate and functional status was evaluated with HAQ score. Body Mass Index (BMI) was selected as a metabolic clinic parameter.

Results:

Male and female patients were similar for disease duration and severity as well as the distribution of diagnosis and treatments (Table 1). In males, BMI was higher than in females (P=0.03) and positively correlated with the age (P=0.01). In female patients, BMI directly correlated with HAQ (P=0.03). The prevalence of anemia (Hb<12) was 13.6% of the study cohort; half of anemic patients had PsA, the others had enteropathic SpA (ESpA). Anemia resulted almost wholly in female patients (99%). In the male group, Hb resulted inversely related to age (P=0.01) and CRP levels (P=0.008). Ferritin was lower in females than in males (P=0.0003). 25(OH)D deficiency (≤20 ng/ml) was present in 23.2% of the cohort: males had lower 25(OH)D than females (P=0.02). Among male patients, disease duration correlated positively with ferritin (P<0.001) and inversely with 25(OH)D (P=0.02). Low levels of serum B12 (≤200 pmol/l) were rare (13.2%), while deficiency in FA (≤4 ng/ml) was frequent (22%) and associated with B12 defect in 31% of cases, with almost similar occurrence in males and females. A diagnosis of ESpA occurred in 55% of cases with B12 deficiency and 62.5% of FA defect, without gender difference. Mean levels of ferritin, 25(OH)D, B12, and FA did not differ significantly between PsA and SpA patients.

POS1246 COVID-19 IN ITALIAN PATIENTS WITH RHEUMATIC AUTOIMMUNE SYSTEMIC DISEASES: RESULTS OF A NATIONWIDE SURVEY STUDY

Background:

SARS-CoV-2 infection poses a serious challenge for patients with rheumatic autoimmune systemic diseases (ASD), characterized by marked immune-system dysregulation and frequent visceral organ involvement.

Objectives:

To evaluate the impact of Covid-19 pandemic in a large series of Italian patients with ASD.

Methods:

Our multicenter telephone survey (8-week period, March-April 2020) included a large series of 2,994 patients (584 M, 2,410 F, mean age 58.9±13.4SD years) with ASD followed at 34 tertiary referral centers of 14 regions of northern, central, and southern Italian macro areas, characterized by different prevalence of SARS-CoV-2 infection. According to currently used criteria, Covid-19 was classified as definite Covid-19 (signs or symptoms of Covid-19 confirmed by positive oral/nasopharyngeal swabs at PCR testing) or highly suspected Covid-19 (signs or symptoms highly suggestive of Covid-19, but not confirmed by PCR testing due to limited availability of virological tests in that period). The results were analyzed performing the Odds Ratio by Java-Stat 2-way Contingency Table Analysis.

Results:

The main findings of the survey study revealed a significantly increased prevalence of Covid-19 in:

a.the whole series of ASD patients (definite Covid-19: 22/2994, 0.73%; p=0.0007;

definite Covid-19 plus highly suspected Covid-19: 74/2,994, 2.47%; p<0.0001) when compared to Italian general population of Covid-19 infected individuals (349/100000 = 0.34%; data from Italian Superior Institute of Health;

https://www.epicentro.iss.it/en/coronavirus/sars-cov-2-national-surveillance-system).

b.the subgroup of patients with connective tissue diseases or systemic vasculitis (n = 1,901) compared to the subgroup of inflammatory arthritis (n = 1,093), namely rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis (definite Covid-19: 19/1,901, 0.99%, vs 3/1,093, 0.27%; p=0.036; definite Covid-19 plus highly suspected Covid-19: 69/1,901, 3.6%, vs 5/1,093, 0.45%; p<0.0001)

c.the subgroup of patients with pre-existing interstitial lung involvement (n = 526) compared to those without (n = 2,468) (definite Covid-19: 10/526, 1.90%, vs 12/2,468, 0.48%; p=0.0015; definite Covid-19 plus highly suspected Covid-19: 33/526, 6.27%, vs 41/2,468, 1.66%; p<0.0001).

Of interest, the prevalence of Covid-19 did not correlate with presence/absence of different comorbidities, mainly diabetes, cardio-vascular and/or renal disorders, as well as of ongoing treatments with biological DMARDs; while patients treated with conventional DMARDs showed a significantly lower prevalence of Covid-19 compared to those without. Covid-19 was more frequently observed in the patients’ populations from northern and central compared to southern Italian macro area with lower diffusion of pandemic. Clinical manifestations of Covid-19, observed in 74 patients, were generally mild or moderate; 4/9 individuals requiring hospital admission died for severe pneumonia.

Conclusion:

The prevalence of Covid-19 observed in ASD patients during the first wave of pandemic was significantly higher than that observed in Italian general population; moreover, the actual prevalence of Covid-19 might be underestimated due to the high number of mild variants as well as the possible clinical overlapping between these two conditions. Patients with ASD should be invariably regarded as ‘frail patients’ during the pandemic course, considering the risk of worse outcome in the acute phase of Covid-19, as well as the potential long-term effects of viral infection.

The statistically significant association of Covid-19 with connective tissue diseases/systemic vasculitis, as well as with pre-existing interstitial lung involvement, suggests the presence of distinct clinico-pathological ASD subsets, characterized by markedly different patients’ vulnerability to SARS-CoV-2 infection.

POS1349 THE JOINT INVOLVEMENT IN ADULT ONSET STILL’S DISEASE IS CHARACTERISED BY A PECULIAR MAGNETIC RESONANCE IMAGING AND A SPECIFIC TRANSCRIPTOMIC PROFILE

Background:

Adult onset Still’s disease (AOSD) is a rare systemic autoinflammatory disease and joint involvement is one of its clinical manifestations [1]. Arthritis, either oligoarthritis or bilateral symmetrical rheumatoid arthritis-like polyarthritis, is another common clinical feature of AOSD, with a migrating pattern at the beginning and becoming stable over the time [1].

Objectives:

The aims of the study were to assess joint involvement in AOSD by using magnetic resonance imaging (MRI), to describe main patterns of involvement, and associated clinical characteristics, and to evaluate the global transcriptomic profile of synovial tissues in AOSD to elucidate possible pathogenic pathways involved with.

Methods:

AOSD patients, who underwent to magnetic resonance imaging (MRI) exam on joints, were assessed to describe patterns of joint involvement and associated clinical characteristics. Some synovial tissues were collected for RNA-sequencing purposes.

Results:

In this study, 31 patients with AOSD (mean age 42.3 ± 15.2 years, 54.8% male gender), who underwent to at least one MRI exam on joints, were assessed. The most common MRI finding was the presence of synovitis on 60.5%, mainly in peripheral affected joints. MRI revealed a mild to moderate proliferative synovitis, as thickening of the synovial membrane, with low to intermediate signal intensity on T1-weighted images and intermediate to high signal intensity on T2-fat saturated weighted and STIR images, suggesting the presence of a hyperplastic than of a hypertrophied synovial tissue. Bone oedema and bone erosions were reported on 34.9% and 25.6% MRI exams, respectively. In all patients but one, bone erosions were synchronous with bone oedema, overlapping completely the locations. Assessing clinical characteristics in patients with MRI-erosions, a higher prevalence of splenomegaly, a more frequent chronic disease course, lower levels of erythrocyte sedimentation rate and ferritin was observed.

Assessing the synovial tissues of some AOSD patients, a moderate perivascular mononuclear infiltrate in the sub-lining stroma of hip synovial tissues was observed, whereas the lining cells were relatively unremarkable. In addition, interleukin (IL)-1β, IL-6, TNF, and heavy ferritin subunit (FeH) were found on AOSD synovial tissues.

An RNA-sequencing analysis assessed the global transcriptomic profile of synovial tissues on AOSD patients and matched-controls. Assessing IL-1 pathway, we found an increased expression of il1a, il1b, il1rap, il1r1, il18r1, and Il18bp on AOSD tissues when compared with controls. In IL-6 pathway, we found an increased expression of il6 and il6st/gp130 on AOSD synovial tissues whereas an increased expression of il6r was shown on the controls. Among genes involved in TNF pathway, tnf, traf1, traf2, tnfaip3 and tnfrsf1a resulted to be more expressed in AOSD synovial tissues than in controls. Finally, fth1 and ftl were more expressed in AOSD patients than controls, when we explored the iron uptake and transport pathway.

Conclusion:

A peculiar MRI pattern of joint involvement in AOSD was reported; the most common finding was the presence of synovitis, characterised by intermediate to high signal intensity on T2-fat-saturated weighted and STIR images. Bone erosions and bone oedema were also observed. This MRI pattern was associated with a hyper-activation of IL-1, IL-6, and TNF pathways together with a hyper-expression of ferritin genes on AOSD synovial tissues.

SAT0435 SECUKINUMAB EFFICACY In PsA PATIENTS IS DEPENDENT ON PATIENTS’ BODY MASS INDEX

Background:

Psoriatic arthritis (PsA) is a chronic inflammatory arthritis burdened by a series of metabolic comorbidities. Among them, obesity is very common in PsA, with a prevalence of 27%, as confirmed by a recent Spanish work (1). Obesity in PsA has been associated with higher disease activity and a worse effectiveness of biologic treatment in PsA. This has been certainly proven for anti-TNF-α as demonstrated by different studies reporting, in obese patients, a reduced treatment response and adherence. In particular, results coming from DAN-BIO and ICE-BIO registries, (2) point out that obesity is a risk factor for anti-TNF withdrawal due to poor response. Although a recent multi-centric, retrospective study in Spain has shown that obese subjects with psoriasis have a poor therapeutic response to secukinumab, (3) no data are currently available for secukinumab in PsA obese patients.

Objectives:

Our studies focused on the relationship between BMI and clinical response to secukinumab in PsA.

Methods:

We, retrospectively, analysed clinical data of 100 patients with PsA (57% female, median age 53 (49.2-55 years)) satisfying CASPAR criteria (4) for PsA, afferent to our clinic, who were treated with secukinumab. Patients were divided into 2 groups based on BMI (BMI<25 normal weight and BMI≥25 overweight/obese).

Results:

In the normal weight group 75% were female, median age was 50.5 (41-54.6), median BMI was 22 (20.2-23.3) and median DAPSA was 19.19 (15.6-24.2). The features of the overweight/obese patients were similar to the normal weight group (48% were female, median age 54 (50-59), median BMI 29 (27.4-30.1) and median DAPSA 21.2 (19-24.4)). Clinical response to therapy, evaluated as the achievement of low disease activity or remission according to DAPSA, was recorded 6 months after starting treatment. After 6 months of treatment, the variation of the DAPSA was inversely related to BMI: overweight/obese patients had in fact a better response to secukinumab compared to normal weight patients. By using a correlation coefficient (SPSS), to analyze the degree of association between BMI and DAPSA, we observed that BMI and DAPSA are inversely related in our PsA patients (p=0.05). Interestingly, analysis of serum levels of IL-17 in 20 obese patients compared to 20 non-obese patients, showed significantly higher serum levels of IL-17 in the former (Figure 1), indicating IL-17 as a key cytokine driving inflammation in PsA obese patients.

Conclusion:

These are the first data about clinical response to secukinumab in obese PsA patients. Our results support the relevance of IL-17 in driving systemic inflammation in obese PsA patients, also providing evidence that obese patients may have a better response to secukinumab compared to non-obese patients. Interestingly, this effect was not

FRI0284 EFFECTIVENESS AND SAFETY OF SECUKINUMAB IN NAÏVE OR TNF-INHIBITORS FAILURE PSORIATIC ARTHRITIS PATIENTS IN REAL LIFE: A 24-MONTHS PROSPECTIVE MULTICENTER STUDY

Background:

Secukinumab (SEC) is a novel treatment for psoriatic arthritis (PsA),but data from real life are still missing.

Objectives:

1)to evaluate the effectiveness and safety of a wide cohort of PsA patients on SEC followed in 7 Italian rheumatologic centers for 24 months;2)to compare the features and disease activity indices of SEC-treated PsA patients subdivided in naïve biological drugs (group A) and in TNF-inhibitors (TNFi) failure patients (group B).

Methods:

Consecutive patients with moderate-severe PsA,who begun SEC treatment were evaluated prospectively.Data on disease characteristics,previous and ongoing treatments,comorbidities and duration of follow-up were collected.Disease activity,functional and clinimetric scores and biochemical values were recorded at baseline (t0),at 6 (t6),12 (t12),and 24 (t24) months.Anova (Kruskal Wallis) and generalized linear models were used to compare variables over time.Infections and adverse events were also collected.

Results:

PsA345patients [38.84% men;mean age 52.9 (11.27) years] were enrolled;mean treatment duration was 18.53 (9.97) years.SEC was prescribed as first line biologic treatment in 133 (38.55%) patients and as second or more line biological treatment in 212 (61.45%) patients. Enthesitis was present as a prominent manifestation in 61.44% of patients (Figure 1).In all population significant decrease in tender/swollen joints;Visual Analogue Scale of pain (VASp) and general health (VASgh);Psoriasis Area Severity Index (PASI);Leeds Enthesitis Index (LEI);number of dactylitis;Health Assessment Questionnaire modified for spondyloarthritis (HAQ-S);Bath Ankylosing Spondylitis Disease Activity Index (BASDAI);Bath Ankylosing Spondylitis Functional Index (BASFI);C-reactive protein (CRP) was achieved.Effectiveness of all PsA patients was associated to an improvement in Ankylosing Spondylitis disease activity score (ASDAS) [t0=3.45 (0.69) vs t24=1.48 (0.23);p<0.01] and in Disease Activity in PsA (DAPSA) [t0=29.52 (12.56) vs t24=11.41 (7.63);p<0.001].At t0group Bhad a more erosive (p=0.04) and polyarticular pattern (p=0.04),a longer disease duration (p=0.001),a greater prevalence (p=0.04) of psoriasis and dactylitis (p=0.01),a higher PASI score (p=0.01),while no significant difference was observed for uveitis,inflammatory bowel diseases,enthesitis.At t24group Ashowed better physical functioning and lower disease activity compared togroup B[HAQs A vs B=0.03 (0.16) vs 0.69 (0.73);BASDAI A vs B=2.37 (0.66) vs 4.27 (2.33);ASDAS A vs B=1.4 (0.62) vs 1.99 (0.86);CRP A vs B=2.03 (1.94) vs 3.11 (1.55) mg/L;DAPSA A vs B=7.03 (3.57) vs 12.41 (8.05)].After t24 of treatment 74.6% ofGroup Aand 72.8% ofGroup Barticular had an inactive\low disease activity (MDA),accordingly to ASDAS and DAPSA respectively.Forty-three patients (12.46%) stopped the treatment during the follow-up mainly because of primary or secondary loss of efficacy (29 and 24, respectively).Only 14 patients suspended SEC because of adverse events (of which 9 for reactions at site of injection).A low number of episodes of mild infections (16) occurred;SEC was instead permanently discontinued in 7 cases for:oral refractory mucositis (3);recurrent aphthosis (2);diverticulitis (2).The retention rate at t24 was good in the whole population.Interestingly no differences were found betweenGroup AandB(p=0.815).

Conclusion:

In a real life clinical setting,SEC was safe and effective in PsA. as shown by a significant decrease of DAPSA and ASDAS over a 24-months follow up.

AB0640 LONG-TERM EFFECTIVENESS AND DRUG SURVIVAL OF GOLIMUMAB IN PATIENTS AFFECTED BY PSORIATIC ARTHRITIS WITH CUTANEOUS INVOLVEMENT

Background:

Psoriatic arthritis (PsA) is a chronic immune-mediated disease associated with psoriasis (PsO). Overexpression of inflammatory cytokines such as tumor necrosis factor (TNF)-α plays a key role in the pathogenic mechanisms. Golimumab (GLM) is a fully human monoclonal antibody IgG1k neutralizing TNF-α approved for PsA and PsO, but effectiveness evaluation in real life remains a crucial issue.

Objectives:

In a real-life setting, to determine the survival rate of GLM (drug survival) at 48 months in the global population, in different clinical settings, and the effectiveness of GLM in improving joint symptoms and cutaneous manifestations in patients affected by moderate to severe PsA with cutaneous involvement.

Methods:

We collected retrospectively from 1 January 2014 to 31 December 2019 data from 105 patients affected by PsA, according to the Classification for Psoriatic Arthritis (CASPAR) criteria, who started treatment with GLM. Inclusion criteria were age > 18 years and had a diagnosis of PsA > 6 months, the presence of peripheral arthritis (at least one active joint) and active PsO. Relevant anamnestic, clinical, biochemical data and biological treatment line were collected at baseline (T0) and after 6 (T6), 12 (T12), 24 (T24) and 48 (T48) months of GLM treatment. Comparisons between baseline and 48 months continuous variables were performed using a paired t-test or a Wilcoxon signed-rank test for paired samples. The drug survival rates were analyzed using Kaplan-Meier estimates. Drug survival rates were read from the Kaplan-Meier survival curves. Differences in drug survival between groups were analyzed using a log-rank (Mantel-Cox) test, by stratifying for sex, BMI, smoking habit and line of treatment. A p-value <0.05 was considered as statistically significant.

Results:

Peripheral arthritis was present in 67 (63.8%) cases, axial disease in 37 (35.3%), enthesitis and PsO as prominent manifestations in 82 (78%) and 84 (80%) patients respectively. Erosive disease was present in 38 (36.2%) of patients at baseline. The most frequent comorbidities were MetS described in 20 (19%) patients and cardiovascular disease described in 33 (31.4%) patients, probably due to the high incidence of smokers (33 (31.4%) of patients) and to the elevate BMI score (27.1±6.0). At 48 months, the 42% (44 of 105) (figure 1A) of the patients have discontinued therapy; the most frequent reason was insufficient response/loss of efficacy (30 patients (28.6%) out of 105). Unexpectedly, no statistical significant difference emerged according to gender (p=0.652), BMI (p=0.655), smoking habit (p=0.466) and line of treatment (p=0.208) (figure 1B-E). Finally, the effectiveness of GLM in improving joint symptoms and cutaneous manifestations was confirmed once again, with a statistical significant improvement at 48 months in clinical (BASDAI p<0.0001; PASI p<0.01; DAPSA p<0.0001) and biochemical (CRP<0.05) data.

Conclusion:

This multicentric study revealed a high drug persistence of GLM in real-life patients, although the presence of comorbidities. Unlike what is known in literature, our study population presented no differences in terms of clinical response and efficacy between male and female, smokers and no-smokers, obese and health-weight patients, different line of treatment. On the other hand, efficacy and safety of GLM has been demonstrated once again also in real-life treatments.

Evidence-based algorithm for diagnosis and assessment in psoriatic arthritis: results by Italian DElphi in psoriatic Arthritis (IDEA)

Psoriatic arthritis (PsA) is a chronic inflammatory disease involving skin, peripheral joints, entheses, and axial skeleton. The disease is frequently associated with extrarticular manifestations (EAMs) and comorbidities. In order to create a protocol for PsA diagnosis and global assessment of patients with an algorithm based on anamnestic, clinical, laboratory and imaging procedures, we established a DElphi study on a national scale, named Italian DElphi in psoriatic Arthritis (IDEA). After a literature search, a Delphi poll, involving 52 rheumatologists, was performed. On the basis of the literature search, 202 potential items were identified. The steering committee planned at least two Delphi rounds. In the first Delphi round, the experts judged each of the 202 items using a score ranging from 1 to 9 based on its increasing clinical relevance. The questions posed to experts were How relevant is this procedure/observation/sign/symptom for assessment of a psoriatic arthritis patient? Proposals of additional items, not included in the questionnaire, were also encouraged. The results of the poll were discussed by the Steering Committee, which evaluated the necessity for removing selected procedures or adding additional ones, according to criteria of clinical appropriateness and sustainability. A total of 43 recommended diagnosis and assessment procedures, recognized as items, were derived by combination of the Delphi survey and two National Expert Meetings, and grouped in different areas. Favourable opinion was reached in 100% of cases for several aspects covering the following areas: medical (familial and personal) history, physical evaluation, imaging tool, second level laboratory tests, disease activity measurement and extrarticular manifestations. After performing PsA diagnosis, identification of specific disease activity scores and clinimetric approaches were suggested for assessing the different clinical subsets. Further, results showed the need for investigation on the presence of several EAMs and risk factors. In the context of any area, a rank was assigned for each item by Expert Committee members, in order to create the logical sequence of the algorithm. The final list of recommended diagnosis and assessment procedures, by the Delphi survey and the two National Expert Meetings, was also reported as an algorithm. This study shows results obtained by the combination of a DElphi survey of a group of Italian rheumatologists and two National Expert Meetings, created with the aim of establishing a clinical procedure and algorithm for the diagnosis and the assessment of PsA patients. In order to find accurate and practical diagnostic and assessment items in clinical practice, we have focused our attention on evaluating the different PsA domains. Hence, we conceived the IDEA algorithm in order to address PsA diagnosis and assessment in the context of daily clinical practice. The IDEA algorithm might eventually lead to a multidimensional approach and could represent a useful and practical tool for addressing diagnosis and for assessing the disease appropriately. However, the elaborated algorithm needs to be further investigated in daily practice, for evidencing and proving its eventual efficacy in detecting and staging PsA and its heterogeneous spectrum appropriately.

Accelerated bone turnover identifies hemiplegic patients at higher risk of demineralization

Immobilization osteoporosis represents a severe complication in hemiplegic patients (HPs), causing fragility fractures, which may occur during rehabilitation reducing functional recovery and survival. The aim of the study was to investigate determinants of bone loss, independent from length of immobilization, which may be useful in early identification of HPs at higher risk of demineralization. Forty-eight HPs of both sexes underwent anthropometric measurements, evaluation of scores of spasticity and of lower limb motory capacity. Laboratory tests were performed. On serum: calcium; phosphorus; creatinine; ALP; iPTH; 25(OH) vitamin-D; sex hormones; Δ4-androstenedione; DHEA-S; insulin; IGF-1; FT3; FT4; TSH; c-AMP. On urine: c-AMP and calcium/creatinine ratio. Two bone turnover markers were measured: serum osteocalcin (BGP) and urinary deoxypyridinoline (DPD). Bone mineral density was determined at both femoral necks, defining a percentage difference in bone loss between paretic and non-paretic limb, thus controlling for the complex cofactors involved. Only bone turnover markers significantly and directly correlated with the entity of demineralization, controlling for age, sex and length of immobilization in the multivariate analysis (BGP coefficient estimate=0.008; SE=0.003; p=0.020; DPD coefficient estimate=0.005; SE=0.002; p=0.036). BGP and DPD are not dependent on anthropometric and endocrine-metabolic parameters, disability patterns and duration of immobilization, thus represent independent determinants of the degree of demineralization. A cutoff was defined for BGP and DPD above which subjects show significantly greater risk of demineralization. The immobilization event generates more severe bone loss when it occurs in subjects with higher bone turnover. BGP and DPD measurements may be of primary importance for early identification of HPs at risk, with relevant preventive implications.

PHYSIOPATHOLOGY OF OSTEOPOROSIS: FROM RISK FACTORS ANALYSIS TO TREATMENT

Osteoporosis represents a relevant health issue, being the first cause of bone fractures in the elderly with subsequent implications in terms of survival and social costs. The improved knowledge about the physiopathology of this disease has led to a new definition of Osteoporosis, which shifts the attention from the “"decrease in bone mass"” to several elements related to what has globally been defined as bone quality. In fact, it has been shown that clinical risk factors affecting bone homeostasis coincide with osteoporosis risk factors. The evaluation of such clinical risk factors is an important element in the assessment of the global fracture risk. The availability of instruments for the assessment of the global fracture risk also suggests a change in the clinical perspective and raises new questions as yet unanswered.

From primary progressive aphasia to corticobasal syndrome: two clinical and rCBF functional reports

We describe two cases, both presenting with a 2-year history of isolated language disorders, one compatible with logopenic variant and the other with non-fluent variant of primary progressive aphasia (PPA). Afterwards, each developed a corticobasal syndrome (CBS) with alien limb phenomenon and a multi-domain cognitive impairment. Regional cerebral perfusion (rCBF) study using 99mTc-ECD single photon emission computed tomography (SPECT) revealed hypoperfusion patterns consistent with these aphasia types and with the presence of limb apraxia. We report two cases of PPA variants associated with CBS and we suggest that SPECT rCBF correlates can be useful in making a differential diagnosis within the PPA spectrum.

[Methotrexate in the treatment of peripheral arthritis in ulcerative colitis]

OBJECTIVE

To evaluate efficacy of methotrexate treatment in peripheral arthritis of ulcerative colitis.

METHODS

We studied 18 patients (10/8 M/F; mean age: 38.90 yrs; range: 21-65 yrs), with peripheral arthritis (14 with polyarticular, 4 with oligoarticular subset) associate ulcerative colitis. Methotrexate 20 mg/week was administered in our patients, who were already receiving mesalazina for inflammatory bowel disease. At baseline, after 3 (T1), 6 (T2) and 12 months (T3) serological parameters (ESR and CRP), functional status (HAQ) and disease activity (VAS, GH, Ritchie articular index) were evaluated.

RESULTS

During the therapy a significant improvement was observed in disease activity, functional status and serological parameters since T1. ESR and CRP did not change at T2 and T3. Instead VAS, GH, Ritchie articular index and HAQ had a significant and gradual improvement from T1 to T3.

CONCLUSION

Methotrexate treatment was efficacious in the treatment of peripheral arthritis associate ulcerative colitis. This drug induced improvement in disease activity, functional status and serological parameters after 3 months of therapy.

[AEL: a rare variant of blood group A]

We have studied an eight-member family. Three of them presented discrepancies between red blood cell and serum tests. The red blood cells fail to react with anti-A, anti-B or anti-AB of any origin. On the other hand, serum grouping tests strongly react with group B cells and fail to react with A1 and A2 cells. Then we performed saliva and adsorption/elution studies in order to demonstrate A or H substances in saliva of secretors. We conclude that the blood belonged to an A weak group named Ael.
