RESUMEN
OBJECTIVE: To present the characteristics of patients with potential difficult-to-treat (D2T) psoriatic arthritis (PsA). METHODS: We used data from the Greek multicentre registry of PsA patients. D2T-PsA was defined as follows: patients with at least 6-months disease duration, who have failed to at least 1 csDMARD and at least 2 bDMARDs/tsDMARDs with a different mechanism of action and have either at least moderate disease activity (MODA) defined as DAPSA > 14, and/or are not at minimal disease activity (MDA). Demographic and clinical characteristics were compared between D2T and non-D2T PsA patients. In two sensitivity analyses, patients classified as D2T solely according to the MODA or MDA criterion were examined separately. RESULTS: Among 467 patients included, 77 (16.5%) were considered D2T and 390 non-D2T PsA. Compared with non-D2T, patients with D2T PsA presented more commonly with extensive psoriasis (p< 0.0001) and were more likely to have higher BMI (p= 0.023) and a history of inflammatory bowel disease (p= 0.026). In the MODA and MDA sensitivity analyses, 7.5% and 12.5% of patients were considered D2T, respectively. In both sensitivity analyses, extensive psoriasis was again identified as an independent variable for D2T PsA (p= 0.001 and p= 0.008, respectively). Moreover, female gender (p= 0.034) in the MODA analysis and axial disease (p= 0.040) in the MDA analysis were independent variables for D2T PsA. CONCLUSION: Despite the availability of therapies, D2T PsA is common in real-life cohorts of patients with PsA and extensive psoriasis. High BMI, female gender, axial-disease, and history of IBD were also associated with D2T PsA.
RESUMEN
Background: Psoriatic arthritis (PsA) is a heterogenous chronic inflammatory disease affecting skin, joints, entheses, and spine with various extra-musculoskeletal manifestations and comorbidities. The reported patient, disease and treatment characteristics in the modern therapeutic era are limited. Methods: In this cross-sectional, multi-centre, nationwide study, we recorded the demographic, clinical, and therapeutic characteristics as well as the comorbidities of patients with PsA seen for 1 year (1/1/2022-31/12/2022). Results: 923 patients (55% females) with a median (IQR) age of 57 (48-65) years and a mean disease duration of 9.5 years were enrolled. Family history of psoriasis and PsA was noted in 28.3% and 6.3%, respectively. Most patients had limited psoriasis (BSA<3: 83%) while enthesitis, dactylitis, nail and axial involvement reported in 48.3%, 33.2%, 43% and 25.9% of patients, respectively. Regarding comorbidities, approximately half of patients had dyslipidaemia (42%) or hypertension (45.4%), 36.8% were obese and 17% had diabetes while 22.7% had a depressive disorder. Overall, 60.1% received biologics and among them more patients treated with anti-IL-17 or -12/23 agents were on monotherapy (64.2%) compared to those on TNFi monotherapy (49.4%, p=0.0001). The median PsA activity as assessed by the DAPSA score was 6 (IQR: 2.3 - 13.1) with 46% of patients reaching minimal disease activity status (MDA). Conclusion: In this large, real life, modern cohort of patients with PsA with frequent comorbidities who were treated mainly with biologics, almost half achieved minimal disease activity. These results show the value of existing therapeutic approaches while at the same time highlight the existing unmet needs.
RESUMEN
AIM OF THE STUDY: To evaluate the current disease characteristics, treatment and comorbidities of rheumatoid arthritis (RA) in Greece. METHODS: Multicenter, cross-sectional study with a 9-month recruitment period between 2015 and 2016. Demographics, disease characteristics, treatment and comorbidities were collected via a web-based platform. RESULTS: 2.491 RA patients were recruited: 96% from tertiary referral centers, 79% were females with a mean age of 63.1 years and disease duration of 9.9 years. Fifty-two percent were rheumatoid factor and/or anti-CCP positive, while 41% had erosive disease. Regarding treatment, 82% were on conventional synthetic disease modifying anti-rheumatic drugs (csDMARDs), 42% on biologic DMARDs (TNFi: 22%, non-TNFi: 20%) and 40% on corticosteroids (mean daily dose: 5.2 mg). Despite therapy, 36% of patients had moderate and 12% high disease activity. The most frequent comorbidities were hypertension (42%), hyperlipidemia (33%), osteoporosis (29%), diabetes mellitus (15%) and depression (12%). Latent tuberculosis infection (positive tuberculin skin test or interferon gamma release assay) was diagnosed in 13 and 15.3% of patients, respectively. Regarding chronic viral infections, 6.2% had history of herpes zoster while 2% and 0.7% had chronic hepatitis B and C virus infection, respectively. A history of serious infection was documented in 9.6%. Only 36% and 52% of the participants had ever been vaccinated against pneumococcus and influenza virus, respectively. CONCLUSION: This is one of the largest epidemiologic studies providing valuable data regarding the current RA characteristics in Greece. Half of patients were seropositive but despite therapy, half displayed residual disease activity, while preventive vaccination was limited.
RESUMEN
Rheumatoid arthritis is a common autoimmune disease leading often to joint destruction and reduced quality of life. We report a case of a young woman with rheumatoid arthritis with fever and rapid, destructive joint involvement verified with magnetic resonance imaging. She had failed therapy with methotrexate and leflunomide, anti-TNF, IL-6 inhibitor, B cell depletion and IL-1RA. Her laboratory results remained insignificant despite the aggressiveness of her disease. In this case, the patient only partly responded to anakinra but developed side effects, and therefore was switched to Canakinumab that led to sustained remission. There are no clear biomarkers or other clues in order to separate early in the beginning of the disease course if a polyarticular inflammatory spectrum can be IL-1ß driven. The young age of the patient at onset of disease, its aggressive course, inflammatory fever without significant laboratory inflammatory markers but with polyarthritis affecting small joints, may raise the suspicion of an IL-1ß-driven disease and alert the treating rheumatologist to the use of IL-1ß inhibitors early in the disease course.
