Introduction: Psoriatic Arthritis (PsA) is a chronic inflammatory arthritis and occurs in association with psoriasis, a chronic recurring and disfiguring skin disease. There is increasing recognition that both conditions are associated with multitude of co-morbidities.Objective: To delineate the clinical characteristics and co-morbidities in PsA patients attending a rheumatology clinic in Kathmandu valley.Material and Methods: Patients with already developed psoriasis who were seeking medical attention for arthritis during the period between January 2013 to December 2015 were prospectively enrolled. Patients were evaluated both by a dermatologist and a rheumatologist. A structured format was used to record relevant clinical information on psoriasis, PsA, and co-morbidities.Results: Among 55 patients with PsA, all were found to have plaque psoriasis mainly affecting extensor surfaces (64%), multiple areas (16%), and scalp (11%). Nail involvement was observed in 22% of patients. Symmetric polyarthritis was the most frequent (26%) form, followed by oligoarthrtis (18%), distal interphalangeal (DIP) joint arthritis (16%),spondyloarthritis (13%), and enthesitis-dactylitis (7%). Two thirds of patients were either overweight or obese. Almost half (47%) were current or past smokers. Diabetes or pre-diabetes was observed in 7% of cases. Hypertension, hyperlipidemia and ischemic heart disease (IHD) were present in 20%, 16%, and 5% respectively. Fatty liver disease was observed in 13% of the tested patients and 15% of patients were on some psychotropic drugs.Conclusion: Psoriasis with PsA was associated with both cardiovascular and non-cardiovascular co-morbidities. Doctors treating patients with these disorders should consider associated co-morbidities for better patient outcome.

Abstract Objectives Our aim is to understand clinical characteristics, real-life treatment strategies, outcomes of early PsA patients and determine the differences between the inception and established PsA cohorts. Methods PsArt-ID (Psoriatic Arthritis- International Database) is a multicentre registry. From that registry, patients with a diagnosis of PsA up to 6 months were classified as the inception cohort (n==388). Two periods were identified for the established cohort: Patients with PsA diagnosis within 5–10 years (n = 328), ≥10 years (n = 326). Demographic, clinical characteristics, treatment strategies, outcomes were determined for the inception cohort and compared with the established cohorts. Results The mean (s.d.) age of the inception cohort was 44.7 (13.3) and 167/388 (43.0%) of the patients were male. Polyarticular and mono-oligoarticular presentations were comparable in the inception and established cohorts. Axial involvement rate was higher in the cohort of patients with PsA ≥10 years compared with the inception cohort (34.8% vs 27.7%). As well as dactylitis and nail involvement (P = 0.004, P = 0.001 respectively). Both enthesitis, deformity rates were lower in the inception cohort. Overall, 13% of patients in the inception group had a deformity. MTX was the most commonly prescribed treatment for all cohorts with 10.7% of the early PsA patients were given anti-TNF agents after 16 months. Conclusion The real-life experience in PsA patients showed no significant differences in the disease pattern rates except for the axial involvement. The dactylitis, nail involvement rates had increased significantly after 10 years from the diagnosis and the enthesitis, deformity had an increasing trend over time.

Psoriatic arthritis is an inflammatory arthritis, most commonly occurring several years after the onset of psoriasis. Psoriatic arthritis is associated with many comorbidities, including diabetes mellitus, nonalcoholic fatty liver disease, fibromyalgia, and cardiovascular disease. Dermatomyositis is an inflammatory myopathy primarily affecting the skin and muscles. As per literature review, cases of psoriasis and dermatomyositis have been reported. In most published cases, the courses of these diseases develop independently. This is the case of a 45-year-old woman initially diagnosed with psoriatic arthritis who developed concurrent dermatomyositis. The methods used were PubMed search and UpToDate search.

Chapter 33 discusses psoriatic arthritis, which is a seronegative spondyloarthropathy (SpA) affecting the peripheral and axial skeleton that may precede skin manifestations. Psoriatic arthritis is a challenging diagnosis because it often initially presents without psoriasis, lacks specific serologic markers, and resembles osteoarthritis and other inflammatory arthropathies. It is associated with joint erosions, destruction, and ankylosis often involving the distal interphalangeal (DIP) joints. Radiography is the primary imaging modality for initial diagnosis and monitoring disease progression and treatment efficacy. Skin and nail involvement and characteristic imaging findings are key criteria for diagnosis. MRI and US of symptomatic joints and/or MRI of the sacroiliac (SI) joints may be useful in clinically challenging cases.

The treatment of psoriatic arthritis (PsA) makes use of many agents. Most of them are used for the treatment of other forms of inflammatory arthritis or the management of cutaneous manifestations of psoriasis. Although a number of medications are effective in the treatment of both rheumatoid arthritis (RA) and PsA, trials involving some classes of biologic agents indicate that patients with RA and PsA may show different responses to certain drug classes. Treatment of the different elements of PsA includes coordinated interventions to address the major domains of the disease, including peripheral and axial arthritis, enthesitis, dactylitis, and skin and nail involvement.

Nonalcoholic Fatty Liver

Background & Aims: Mild iron overload is frequently reported in patients with nonalcoholic fatty liver disease (NAFLD). Hepcidin is the master iron-regulatory peptide and hemojuvelin (HJV) is the key regulator of iron-dependent secretion of hepcidin. The aims of this study were to evaluate serum HJV and hepcidin levels in patients with biopsy-proven NAFLD with and without hepatic iron overload, and to identify potential associations of HJV and hepcidin with the clinical characteristics of the patients enrolled. Methods: Serum levels of HJV and hepcidin were measured in 66 NAFLD patients with (n=12) and without (n=54) iron overload, and controls (n=35) by enzyme-linked immunosorbent assay. Hemojuvelin and hepcidin levels were assessed in relation to clinical characteristics and liver histologic evaluation of the participants. Results: Significantly lower serum HJV (281.1 [239.2-353.6] vs. 584.8 [440.3-661] ng/ml, p<0.001) and similar serum hepcidin levels (60.5±31.1 vs. 55.8±11.9 ng/ml, p=0.285) were found in NAFLD patients when compared to controls. İron-overloaded NAFLD patients had significantly lower HJV (249.9 [187.6-296.3] vs. 292.9 [243-435] ng/ml, p=0.032) and significantly higher hepcidin (78.4±35.5 vs. 56.5±28.9ng/ml, p=0.027) levels than NAFLD patients without iron overload. Fibrosis stage was significantly higher in iron overloaded NAFLD group (p<0.001). Ferritin levels correlated significantly both with HOMA-IR (r=0.368, p=0.002) and fibrosis stage (r=0.571, p<0.001). Conclusions: Our findings suggest that HJV levels are low in NAFLD and even lower in iron overloaded NAFLD, while hepcidin levels are higher in NAFLD with iron overload. The gradually decreased HJV and increased hepcidin concentrations in our patients most likely reflect the physiological response to iron accumulation in the liver.

Background:Gender differences in prevalence and disease course are known in various rheumatic diseases; however, investigations of gender difference concerning therapeutical response have yielded variable results.Objectives:The aim of this retrospective study was to investigate, whether a gender difference in response rate to biological disease-modifying antirheumatic drugs (bDMARDs) and apremilast in bDMARD-naïve patients could be observed across the three most prevalent inflammatory arthritis diseases: rheumatoid arthritis (RA), spondylarthritis (SpA) and psoriatic arthritis (PsA). Additionally, a response to individual TNF blockers was investigated in this respect.Methods:Data from bDMARD-naïve RA-, SpA- and PsA-patients from Bioreg, the Austrian registry for biological DMARDs in rheumatic diseases, were used. Patients with a baseline (Visit 1=V1) and follow-up visits at 6 months (Visit 2=V2) and 12 months (Visit 3=V3) were included and response to therapy with TNF-inhibitors (TNFi), furthermore to therapy with rituximab, tocilizumab and apremilast was analyzed according to gender. The remaining bDMARDs were not analyzed due to small numbers. Key response-parameter for RA was disease activity score (DAS28), whereas for PsoA the Stockerau Activity Score for Psoriatic Arthritis (SASPA) and for SpA the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were employed; in addition, the Health assessment Questionnaire (HAQ) was used. Data were analyzed in R Statistic stratified by gender using Kruskal-Wallis and Wilcoxon tests.Results:354 women and 123 men with RA (n=477), 81 women and 69 men with PsA (n=150), 121 women and 191 men with SpA (n=312) were included. No significant differences in biometrics was seen between female and male patients at baseline in all diseases.In RA patients overall DAS28 decreased from baseline (V1) to V2 and V3 (DAS28: V1: male: 4.38 [3.66, 5.11], female: 4.30 [3.68, 5.03], p(m/f) = 0.905; V2: male: 2.66 [1.73, 3.63], female: 3.10 [2.17, 3.98], p(m/f) = 0.015; V3: male: 2.25 [1.39, 3.36], female: 3.01 [1.87, 3.87], p(m/f) = 0.002). For TNF inhibitors (n=311), there was a significant difference between genders at V2 (Fig.1a). Patients receiving Rituximab (n=41) displayed a significantly higher DAS28 at baseline in females, which diminished in the follow up: V1: (p(m/f) p=0.002; V2: p=0.019; V3: p=0.13); response to tocilizumab (n=63) did not show any gender differences.In PsA patients overall SASPA decreased from baseline (V1) to V2 and V3 (SASPA: V1: male: 4.00 [2.80, 5.20], female: 4.40 [2.80, 5.80], p(m/f) = 0.399; V2: male: 2.20 [1.20, 3.50], female: 3.40 [2.00, 5.00], p(m/f) = 0.071; V3: male: 1.80 [0.80, 2.70], female: 3.01 [2.35, 4.80], p(m/f) = 0.001). For TNF inhibitors (n=79), there was a significant difference between genders at V3 (Fig 1a). For Apremilast (n=39), there was a significant difference between genders at V2 (Fig.1c).In SpA patients overall BASDAI decreased from baseline (V1) to V2 and V3 (BASDAI: V1: male: 4.70 [2.88, 6.18], female: 4.80 [3.30, 6.20], p(m/f) = 0.463; V2: male: 3.05 [2.00, 4.60], female: 3.64 [2.62, 5.41], p(m/f) = 0.039; V3: male: 3.02 [1.67, 4.20], female: 3.65 [2.18, 5.47], p(m/f) = 0.016). In V3 a differential BASDAI in response to TNFi (n=299) was observed (Fig.1a).Possible differences of response to individual TNFi (etanercept, infliximab, other TNFi) measured by HAQ were investigated in all diseases together. The difference between male and females was significant at baseline for all 3 TNFi; whereas with the use of ETA the significant difference was carried through to V2 and V3, it was lost with the use of IFX and was variable with the other TNFi (Fig.1b)Figure 1.Conclusion:Female patients showed a statistically lower response to TNFi in all three disease entities (RA, SpA and PsoA) to a variable degree in our homogenous central european population. Interestingly, the difference was not uniform across individual TNFi when measured by HAQ. Gender differences were also seen in response to Apremilast.Disclosure of Interests:Elisabeth Loibner: None declared, Valentin Ritschl: None declared, Burkhard Leeb Speakers bureau: AbbVie, Roche, MSD, Pfizer, Actiopharm, Boehringer-Ingelheim, Kwizda, Celgene, Sandoz, Grünenthal, Eli-Lilly, Grant/research support from: TRB, Roche, Consultancies: AbbVie, Amgen, Roche, MSD, Pfizer, Celgene, Grünenthal, Kwizda, Eli-Lilly, Novartis, Sandoz;, Peter Spellitz: None declared, Gabriela Eichbauer-Sturm: None declared, Jochen Zwerina: None declared, Manfred Herold: None declared, Miriam Stetter: None declared, Rudolf Puchner Speakers bureau: AbbVie, BMS, Janssen, Kwizda, MSD, Pfizer, Celgene, Grünenthal, Eli-Lilly, Consultant of: AbbVie, Amgen, Pfizer, Celgene, Grünenthal, Eli-Lilly, Franz Singer: None declared, Ruth Fritsch-Stork: None declared

Background:Cardiovascular (CVS) diseases are the leading cause of death worldwide and patients with rheumatic diseases have an increased CVS risk including stroke and myocardial infarction (MI) (1-3). CVS risk factors and CVS events are common in SpA (4). Delineating the CVS risk and the association with medications in patients with SpA would be useful.Objectives:The objective of this study was to delineate the CVS risk and the association with medications in patients with SpA.Methods:Patients with SpA and patients with non-specific back pain (NSBP) were identified in rheumatology and orthopedics clinics respectively. Clinical information and CVS events were retrieved. Incidence rates were calculated. Association analysis was performed to determine the CVS risk of SpA and other modifiable risk factors.Results:A total of 5046 patients (SpA 2616 and NSBP 2430) were included from eight centers. Over 56 484 person-years of follow-up, 160 strokes, 84 MI and 262 major adverse cardiovascular events (MACE) were identified. Hypercholesterolemia was more prevalent in SpA (SpA 34.2%, NSBP 28.7%, P<0.01). Crude incidence rates of stroke and MI were higher in SpA patients. SpA was associated with a higher risk of MACE (HR 1.66, 95%CI 1.22-2.27, P<0.01) and cerebrovascular events (HR 1.42, 95%CI 1.01-2.00, p=0.04). The use of anti-tumor necrosis factor (TNF) drugs was associated with a reduced risk of MACE (HR 0.37, 95%CI 0.17-0.80, P=0.01) and cerebrovascular events (HR 0.21, 95%CI 0.06-0.78, P=0.02).Conclusion:SpA is an independent CVS risk factor. Anti-TNF drugs were associated with a reduced CVS risk in these patients.References:[1]Crowson CS, Liao KP, Davis JM, 3rd, Solomon DH, Matteson EL, Knutson KL, et al.

Background:Recent studies have demonstrated an increasing burden of musculoskeletal (MSK) diseases worldwide.1The importance of patient education (PE) is often overlooked in the management of long term inflammatory conditions. The European League Against Rheumatism recommends that PE should be integral to standard of care in inflammatory arthritis.2PE increases patients’ knowledge, skills and confidence in managing their condition and improves patient activation (PA). Evidence shows that improved PA results in better outcomes and improved experiences of care. We previously reported on improved knowledge and confidence amongst a small patient group with psoriatic arthritis (PsA) who had attended a pilot education session.3This education session was delivered to a wider group of patients with PsA over a 12 month period; we report on the evaluation received from this service.Objectives:To provide a PE programme to a wider group of patients with PsA, using a multi-disciplinary team (MDT) approach and to evaluate whether this improved patients’ knowledge, skills and confidence in managing their PsA.Methods:Adult patients with PsA attending their rheumatology clinic appointments were invited to a 2.5 hour MDT education session which covered: 1) a general overview of PsA; 2) medications used in PsA; 3) the role of physiotherapy and occupational therapy; 4) flares and self- management. These were interactive sessions, held in a small group setting to allow for informal discussion and questions to the MDT. Written materials including several booklets and online resources were also provided. Patients evaluated their knowledge or understanding before and after each topic covered, on the same day, using an evaluation tool with1-10 Likert scale items. Changes in ratings were analysed using student’s t-tests. Patients were also asked: which aspects they found particularly helpful; if there was anything they would like to have added/ have more of in the session; whether they found the session helpful; whether they would recommend it to other patients; whether they would be interested in developing a PsA patient support group.Results:Four sessions were held over a 12 month period. A total of 32 patients attended; 10 males and 22 females, across a range of age categories. Disease duration varied from less than1 year to over 10 years. There were statistically significant improvements in all topics covered: mean improvement of 91% in how well informed patients felt about PsA overall (p<0.0001); mean improvement of 74% in confidence in accessing help from the MDT (p<0.0001); mean improvement of 122% in how well informed patients were about medications used in PsA (p<0.0001); mean improvement of 99% in patients’ confidence in self-managing a flare (p<0.0001). Aspects that patients found particularly helpful included “The whole session”, “Asking questions to all different professionals”, “Meeting other sufferers”, “Management of flares”, “Fatigue information” and “Online resources”. Overall, 97% of patients (31 out of 32) found the session helpful and would recommend it to others. Over 40% of patients expressed interest in developing a local PsA support group.Conclusion:Following a 2.5 hour education session, improved knowledge, skills and confidence in managing their PsA was reported by 97% of patients, including patients with disease duration of > 10 years. This supports our previous finding that an interactive, group PsA education programme is a feasible and important adjunct to patient care.References:[1]Sebbag E, Felten R, Sagez F, et al.

Background:Entheseal involvement is a frequent and distinctive feature of psoriatic arthritis (PsA), often under diagnosed. It is especially associated with nail involvement. Because clinical examination is not sensitive enough for the detection of early signs of this involvement, US may be considered as an alternative imaging technique in the diagnosis of enthesopathy.Objectives:The aim of the present study is to evaluate US entheses abnormalities in PsA and their correlation with clinical characteristicsMethods:The study included patients diagnosed with PsA according to the CASPAR criteria. They underwent a thorough clinical examination with special regard to the presence of enthesitis using the Spondyloarthritis Research Consortium of Canada (SPARCC) Enthesitis Index.The US study bilaterally explored entheses at six sites: proximal plantar fascia, distal Achilles tendon, distal and proximal patellar tendon insertion, distal quadriceps tendon and distal brachial triceps tendon. We evaluated the following elemental lesions of enthesis at each site: thickness and structure of the tendon, calcifications, bursae, erosions, power Doppler signal in bursa or enthesis full tendon.Results:Of the 33 patients, 39.4 % were male. The mean age was 51.2±12.5 years. The mean disease duration was 13.5±10.2 years.The mean DAPSA was 22.8± 19.7 [0.1-84.5]: remission(n=9), low activity (n=5),moderate activity (n=11),high activity(n=8).At inclusion, 11 patients (33.4%) patients presented with psoriatic onychopathy (45 fingernails) with a mean mNAPSI of 14.1±16. Out of the 528 entheseal sites, 92 were tender at the palpation (17,4%) with a mean SPARCC at 2.87.A total of 396 entheseal sites were examined by US. In 140 of them (35.35%), US found at least 1 sign indicative of enthesopathy. The most affected tendon was the distal Achilles tendon (42/396), followed by proximal plantar fascia (32/396), distal patellar tendon (20/396), quadriceps tendon (20/396), distal brachial triceps tendon(14/396) and finally proximal patellar tendon (12/396).The most common elemental lesions were enthsophytes (176), erosions (114) and calcifications (50).We found a positive correlation between age and both calcification (r=0,4, p=0.021) and enthesophytes (r=0.479, p=0.005).We found a positive correlation between enthesophyte and the tender and swollen joints count (r= 0.352, p=0.045, r=0.378, p=0.03) and the SPARCC score (r=0.397, p=0.022).Patients with higher BASDAI had thicker tendons (r=0.355, p=0.05).Patients with nail dystrophy had more bursitis and erosions.US scores did not correlate with sexe, disease duration and disease activity measures (ASDAS, DAPSA, DAS28 and PASI). Patients with subclinical entheseal involvement didn’t have higher inflammatory biomarkers (ESR, CRP).Conclusion:US subclinical enthesopthy are not rare in psoriatic arthritis, in particular in patients with active disease.Clinical nail involvement was associated with bursitis and erosions. New studies including larger study groups are required to verify the findings of the present studyDisclosure of Interests:None declared
