Background:Axial Involvement in psoriatic arthritis (PsA) is quite common [1]. Predictors of axial involvement at early-stage of disease haven’t been sufficiently studied.Objectives:To identify predictors of axial involvement in PsA patients (pts) at early-stage of disease.Methods:95 patients (pts) (M/F–47/48) with early PsA fulfilling the CASPAR criteria were included. All pts had peripheral arthritis for≤2 years; no inflammatory back pain (IBP) pts were specifically selected. Mean (Me) age 36.5±10.7 yrs, disease duration 12.2±10.3 mo. Pts underwent standard clinical examination of PsA activity. Me disease activity indexes DAS=4.0±1.4, DAS28=4.2±1.1, BASDAI=4.5±1.6; Me pts global disease activity VAS 56.9±17.1. All patients were evaluated for the presence of IBP by ASAS criteria, underwent sacroiliac joints (SIJs) X-ray (pelvic radiographs) and HLA B27 antigen status study. MRI of SIJs was performed in 79 pts, regardless of IBP presence, on Signa Ovation 0.35T. Radiographic sacroiliitis (R-SI) was identified according to New York criteria (unilateral grade≥3 or bilateral grade≥2). Bone marrow edema/ osteitis on MRI (STIR) was considered active MRI sacroiliitis (MRI-SI). X-ray and MRI results were evaluated by an independent reader. IBP was observed in 63 (66.3%) cases, MRI-SI in 28 of 79 (35.4%) examined cases, R-SI in 29 (30.5%) cases. Skin lesion severity was evaluated as body surface area (BSA) affected: minor at <3%, mild at 3-10%, severe at >10%. Pts were split into 2 groups (gr.): those with axial involvement (axPsA), that is with IBP and/or R-SI and/or MRI-SI; and those without axial involvement (having only peripheral PsA [pPsA]).The axPsA gr. included 65 (68.4%) cases, the pPsA gr. 30 (31.6%) cases. Multi-dimensional step-by-step discriminant analysis was used to identify a group of features that are more typical for the axPsA patients.Results:The following features proved to be the most informative: male sex (р = 0.300), presence of HLA B27 (р = 0.107), mild or high DAS (р = 0.098), skin lesion severity BSA>3% (р = 0.118), and CRP > 5 mg/L (0.038).Sensitivity of model 79.0%, specificity of model 57.7%. Area under ROC curve 0.756; 95% CI (0.642-0.869).Conclusion:It is a combination of features – male sex, HLA-B27 positivity, mild or high activity of peripheral arthritis according to DAS, CRP > 5 mg/L, and BSA> 3% – that constitutes a clinical predictor for the development of axial involvement in early psoriatic arthritis.References:[1]V.

Axial Involvement

Reported data of axial involvement in psoriatic arthritis (PsA) are variable (25–70%). This variability is mainly linked to different ways of defining this feature. Gladman1 established that the prevalence of axial involvement in PsA was close to 50% and that it is associated with HLA-B27. Likewise, psoriasis (PsO) spondylitis, unlike ankylosing spondylitis (AS), is characterized by not having a greater preponderance of the male sex, greater skin involvement, and a less severe course.2

Objective: to determine a set of signs that are prognostically significant for identifying a high-risk axial skeletal lesion in early psoriatic arthritis (ePsA).Patients and methods. Examinations were made in 95 patients (47 men and 48 women) with peripheral arthritis lasting for ≤2 years, who met the 2006 Classification Criteria for Psoriatic Arthritis (CASPAR). The clinical characteristics of the patients were presented in our previously published work. In all the patients, a standard examination was made and the signs of inflammatory back pain (IBP) were identified according to the Assessment of SpondyloArthritis International Society (ASAS) criteria, the presence of human leukocyte antigen B27 (HLA-B27) was determined, and pelvic bone X-ray was done; regardless of whether they had IBP, 79 patients underwent magnetic resonance imaging (MRI) of the sacroiliac joints using a low-field Signa Ovation 0.35 T. Sacroiliitis (SI) diagnosed based on radiography (rSI) was considered reliable if there were bilateral changes corresponding to at least Stage II or unilateral changes corresponding to at least Stage III according to the Kellgren system. SI diagnosed based on MRI (MRI-SI) was regarded as active when osteitis was detected in the STIR mode in the bones adjacent to the joint on at least two slices or in the presence of two signals in a slice. X-ray and MRI results were assessed by an independent radiologist. The extent of a skin lesion was determined from the body surface area (BSA): the extent was regarded insignificant, moderate, and significant with involvements of <3%, 3–10%, and >10%, respectively.The patients were divided into two groups. Group 1 included 65 (68.4%) patients with the manifestations of axial PsA (axPSA): IBP, and/or rSI, and/or MRI-SI; Group 2 consisted of 30 (31.6%) patients without axial manifestations, only with peripheral PsA (pPsA). Multivariate stepwise discriminant analysis was used to identify a group of signs that were most characteristic of axPsA.Results and discussion. Comparative analysis of the two groups showed that there were more males among patients with axPsA than among those with pPsA (39 (60%) and 8 (26.7%), respectively) (p=0.003). HLA-B27 positivity was also more often detected in patients with axPSA than in those with pPsA (30 (46.6%) and 7 (23.3%) patients, respectively) (p=0.02). In the axPSA group, there were significantly more individuals with moderate and high DAS, high CRP levels, and a more severe skin lesion (BSA >3%).The investigators obtained the following discriminant classification rule associated with axPSA: 1.566 (if CRP is >5 mg/L) + 0.957 (if HLA-B27 is positive) + 0.986 (if BSA is >3%) + 1.845 (if DAS is moderate or high) + 0.6 (if the sex is male) >3.751 (p=0.0025). The sensitivity and specificity of the model were 68% and 73%, respectively.Conclusion. The combination of signs, such as male sex, HLA-B27 positivity, high or moderate DAS, CRP >5 mg/L, the extent of skin lesions according to BSA >3%, is prognostically significant for identifying high-risk axial skeletal lesion in ePSA. The proposed mathematical model can be used to screen patients for the early diagnosis of an axial lesion in ePSA.

Background:Evidence on the efficacy of biologics in the treatment of psoriatic arthritis (PsA) patients with axial manifestations affecting 30-70% of PsA patients is limited. Secukinumab (SEC) has provided significant and sustained improvement in the signs and symptoms of active PsA and ankylosing spondylitis.Objectives:This study aims to analyze the experience of using SEC for PsA patients with axial involvement in real-world setting.Methods:Multicentric observational, longitudinal, retrospective study conducted in a tertiary hospital between January 2016 and December 2019. Patients with PsA (CASPAR criteria) and clinical and/or image diagnosis of axial involvement receiving at least one dose of SEC were included. Patients with non-pathological sacroiliacs x-ray and MRI had to have spinal pain VAS ≥4/10 after failure to NSAIDs, prior to the onset of SEC, to be included. Medical records were reviewed to collect demographic and clinical data, features of PsA (manifestations, treatments and activity assessment). Descriptive statistics and then a comparative analysis with the Studentt-test to analyze the effectiveness of SEC were performed.Results:Of 98 PsA patients treated with SEC, 58 (59.2%) had axial involvement, of which 41 (71%) female. Mean age was 54 y.o (SD 10) and average duration of the disease was 10 years (SD 8). All 58 patients had peripheral disease (33% joint erosions), 55 (95%) had psoriasis, 20 (34%) showed dactilitis and 39 (67%) had enthesitis. Sacroiliacs x-ray was damaged in 38 (66%) patients (grade I-IV) and 23 (40%) pathological MRI, with HLAB27+ at 8 (14%) patients. Average BMI was 29 (SD 8), with an obesity rate of 33% (19 pt). Observed comorbidities were hypertension (27 pt, 47%), diabetes mellitus (6 pt, 10%), dyslipidemia (23 pt, 40%), active smoking (18 pt, 31%) and malignancy (6 pt, 10%). Regarding previous treatments, 90% had received cDMARDs, particularly methotrexate (86%) and 40 (69%) had been exposed to at least one bDMARD (15 pt to one, 9 to two, 6 to three and 10 to four or more). 7 patients were on 300 mg dose and 51 patients on 150 mg dose (dose escalation to 300 mg was performed in 16 patients and 44% respond and maintain SEC). Average drug survival time was 1.4 (SD 1) years. At 6 months of SEC therapy, tender and swollen joint count, spinal pain VAS, CRP, ASDAS-CRP and DAPSA had significantly decreased (Table 1). 29 (50%) patients suspended SEC during follow-up due to primary ineffectiveness (8), secondary ineffectiveness (16), adverse events (3), latex allergy (1) and remission (1). Adverse events do not differ from those reported in clinical trials.Table 1.Disease activity assessment at 6 months of secukinumab therapy.Baseline6 months after SECMean differenceP valueSJC4,8±5,41,9±3,1-2,8 (IC95% -3,9 a -1,7)p<0,0001TJC7,7±5,83,9±4,1-3,8 (IC95% -5,1 a -2,4)p<0,0001Spinal pVAS6,1±3,24,2±2,9-1,9 (IC95% -2,4 a -1,4)p<0,0001CRP (mg/L)7,7±9,94,9±5,9-2,9 (IC95% -4,5 a -1,2)p=0,0009ASDAS-CRP2,5±1,91,8±1,3-0,7 (IC95% -0,9 a -0,4)p<0,0001DAPSA27,7±12,116,7±10,4-11 (IC95% -15,3 a -6,8)p<0,0001SJC: swollen joint count, TJC: tender joint count, Spinal pVAS: spinal pain visual analog scale, CRP: C-reactive protein, SEC: secukinumab.Conclusion:Secukinumab in real-world setting provided improvements in the axial and peripheral manifestations of PsA, using both the 150 mg and 300 mg doses.Disclosure of Interests:MARIA MARTIN LOPEZ: None declared, Beatriz Joven-Ibáñez Speakers bureau: Abbvie, Celgene, Janssen, Merck Sharp & Dohme, Novartis, Pfizer, José Luis Pablos: None declared

Axial Involvement

Background:Psoriatic arthritis (PsA) covers a wide spectrum of disease manifestations, including arthritis, enthesitis, dactylitis and axial spondylitis. This range of symptoms presents a challenge to the treating physician. Biologic disease-modifying antirheumatic drugs (bDMARDs) have proven effective through randomized clinical trials; and most international PsA guides include them as main option upon first-line treatment failure. However, studies regarding drug efficacy after bDMARD switching are scarce, lower response rates and drug survival on consecutive lines has been explored in previous research.Objectives:To assess bDMARDs survival after first-line failure in PsA patients treated in a third-level hospital and to determine baseline clinical and laboratory parameters associated with drug survival.Methods:We conducted a retrospective, single-centre study. 47 patients who received a second-line bDMARD were included, with diagnosis of PsA according to the criteria of an expert rheumatologist. All patients were studied according to a standard protocol. Data regarding bDMARD prescribed, baseline characteristics, axial or peripheral involvement and immunological profile (included both HLA-B27 and HLA-Cw6) were extracted. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) at bDMARD start were included, as well. Kaplan-Meier, log-rank analyses and Cox regression models were applied.Results:Of 47 patients receiving a second bDMARD, 55,3% (26) were female and mean (S.D.) age was 40,6 (12,52) years. Median (interquartile range) disease duration was 10,1 (3,7-14,8) years. Prescribed drugs were Adalimumab (ADL) (36,2%, 17), Etanercept (ETN) (27,6%, 13), Infliximab (IFX) (6,4%, 3), Golimumab (GOL) (10,6%, 5), Certolizumab (CTZ) (4,3%, 2), Secukinumab (SCK) (8,5%, 4) and Apremilast (APR) (6,4%, 3). 42,3% cases suffered from axial involvement, rest of the sample (57,6%) presented a pure peripherical form of PsA. HLA-B27 and -Cw6 were assessed in 80,9% (38) and 68,1% (32), respectively; of whom, HLA-B27 carriers were 10,5% and HLA-Cw6 positive, 46,9%. Mean CRP level was 10,25 mg/L and mean ESR was 23,17 mm. Patients showed mean and median global drug retention of 44,57 (29,8-59,3) and 23 months. At 12-month visit, drug survival was 70%, 47% at 24 months, and 33% at 4 years from onset. Mean drug persistence by bDMARD prescribed was: ADL, 62,1 months; ETN, 51,9 months; IFX, 39 months; GOL, 22,8 months; CTZ, 9,5 months; SCK, 13,5 months; and APR, 16,3 months. Through log-rank analyses, differences in drug retention were investigated by several variables. Female sex (30,35m, 16,5-44,2 m.) was identified as statistically significant different than male patients (62,5m, 35,6-89,4m, p=0,021). Although not significant, other differences were remarkable: non-axial involvement, HLA-Cw6 negativity, HLA-B27 positivity and CRP level over 5 mg/L. No differences were found between altered and normal ESR patients.Conclusion:Second-line bDMARD survival is lower in female PsA patients, according to our data and previous bibliography. Despite our reduced sample and possible bias, non-axial involvement, absence of HLA-Cw6, presence of HLA-B27 and higher levels of CRP at biologic onset might be predictors of better drug persistence. Further investigations are required on this field.References:[1]Glintborg B et al.

Axial Involvement

Background:Limited data are available on retention rates of biologic therapy in psoriatic arthritis (PsA) patients (pts) with axial involvement. It has been shown that in the subset of pts with prevalent axial involvement (AS versus PsA and AxSpA versus PsA) a longer duration of anti-TNF-α-therapy was observed as compared to peripheral arthritis [1].Objectives:To compare retention rates of biologic therapy in PsA pts with and without axial involvement in routine clinical practice.Methods:731 pts with PsA according to CASPAR criteria were included in the study. Data were collected from 43 rheumatology clinics over various regions of the Russian Federation. Among the pts, 243 (33.0%) (M/F 132/111) were given biologic therapy. Pts’ age 45.9±12.8 years (yrs), disease duration 8.6±6.5 yrs. Pts underwent standard clinical examination of PsA activity and were split into two groups (gr.), with and without axial PsA (axPsA): axPsA(+) and axPsA(-). Pts in the axPsA(+) gr. had inflammatory back pain by ASAS criteria and/or radiographic sacroiliitis (SI) (unilateral grade≥3 or bilateral grade≥2) and/or active MRI SI and/or typical of axPsA changes of the cervical and/or lumbar spine (marginal/paramarginal syndesmophytes, ankylosis of the facet joints). Pts in the axPsA(-) gr. had only peripheral arthritis. The axPsA(+) gr. included 143 (58.8%) pts, the axPsA(-) gr. 100 (41.2%) pts. 163 (67.1%) pts were treated with TNF inhibitors (TNF-i), 80 (32.9%) pts with interleukin inhibitors (IL-i): 55 pts with Ustekinumab, 25 pts with Secukinumab. During the TNF-i treatment courses Infliximab was given to 34 pts, Adalimumab to 53 pts, Etanercept to 36 pts, Golimumab to 27 pts and Certolizumab Pegol to 8 pts. The observation period lasted 12 months. Treatment retention rates were analyzed using Kaplan-Meier curves and the log-rank test.Results:Analysis of the treatment retention rates revealed statistically significant differences between the axPsA(+) and the axPsA(-) grs. After 12 months of observation, 72.9% of pts in the axPsA(-) gr. continued receiving biologic therapy, while in the axPsA(+) gr. only 53.1% of pts (р=0.0027) received it. The same kind of differences in anti-TNF therapy were found between the axPsA(-) gr. and the axPsA(+) gr.: 82.2% and 62.3% pts respectively (р=0.011) continued receiving TNF-i after 12 months. However no statistically significant differences were found between the two grs. in the treatment retention rates of IL-i therapy: after 12 months of observation 55.5% of axPsA(-) pts and 37% of axPsA(+) pts (р=0.086) continued receiving IL-i.Conclusion:In routine clinical practice, retention rates of biologic therapy were found to be worse in PsA pts with axial involvement. In clinical practice, TNF-i are prescribed twice as often than IL-i. However, considering the need of personalized therapy, in case of axPsA the use of IL-i is preferable because their treatment retention rates don’t depend on axial involvement.References:[1]M. Fabbroni et al. Mediators of Inflammation, 2014.Retention rates of biologic therapy. Differences between axPsA(+) and axPsA(-) pts are statistically significant (р=0.00265, log rank test).Disclosure of Interests:None declared.
