Recomendações sobre diagnóstico e tratamento da artrite psoriásica

Brazilian Society of Rheumatology 2020 guidelines for psoriatic arthritis

Psoriatic arthritis (PsA) is a chronic and systemic immune disease characterized by inflammation of peripheral and/or axial joints and entheses in patients with psoriasis (PsO). Extra-articular and extracutaneous manifestations and numerous comorbidities can also be present. These recommendations replace the previous version published in May 2013. A systematic review of the literature retrieved 191 articles that were used to formulate 12 recommendations in response to 12 clinical questions, divided into 4 sections: diagnosis, non-pharmacological treatment, conventional drug therapy and biologic therapy. These guidelines provide evidence-based information on the clinical management for PsA patients. For each recommendation, the level of evidence (highest available), degree of strength (Oxford) and degree of expert agreement (interrater reliability) are reported.

Health-Related Quality of Life in Psoriatic Arthritis: Findings and Implications

OBJECTIVES

To assess the quality of life (QOL) and its associated factors in patients with psoriatic arthritis (PsA) who would start treatment with biologic drugs at the Brazilian Unified Health System.

METHODS

A cross-sectional study was performed at a single center pharmacy in Belo Horizonte, State of Minas Gerais, Brazil. EQ-5D was used to assess the patients' QOL. The functional status was assessed using the Health Assessment Questionnaire-Disability Index, whereas disease activity was evaluated through the Bath Ankylosing Spondylitis Disease Activity Index and the Clinical Disease Activity Index. Simple and multiple linear regression analyses were performed to assess the factors associated with QOL.

RESULTS

A total of 212 patients with PsA were included, of which 185 (87.3%) reported having some pain/discomfort, and 148 (69.8%) presented some level of anxiety/depression. Patients with PsA had a mean QOL score of 0.651 (SD 0.12) with a significant reduction in female patients, concomitant use of nonsteroidal anti-inflammatory drugs, comorbidity, and worse clinical and functional status. Poor QOL was associated with worse functional status by the Health Assessment Questionnaire-Disability Index, disease activity by the Bath Ankylosing Spondylitis Disease Activity Index, and with diagnoses of osteoporosis, hypothyroidism, and depression.

CONCLUSION

PsA and its associated comorbidities negatively affect the QOL, evidencing the need for a comprehensive and effective clinical approach.

Biologics recommendations for patients with psoriasis: a critical appraisal of clinical practice guidelines for psoriasis

PURPOSE

This review article serves to assess the consistency of recommendations from guidelines on biologic agents for psoriasis, based on the quality evaluation of psoriasis Clinical Practice Guidelines (CPGs).

METHODS

We conducted a systematic literature search to identify CPGs that provide recommendations on diagnosis and treatment for psoriasis. Four reviewers performed a quality assessment of the included CPGs with the Appraisal of Guidelines Research and Evaluation II (AGREE II) Instrument.

RESULTS

A total of 51 sets of CPGs from 22 medical societies or separate working groups fulfilled the inclusion criteria. The overall quality of the eligible sets of guidelines was moderate to high, with an overall average score of 55%The highest domain scores were Score and Purpose (70%) and Clarity of Presentation (68%). A total of 95 biologic agent recommendations were extracted from the 18 recommended CPGs.Three biologic agents (Etanercept, Adalimumab, Ustekinumab) were recommended for pediatric patients. Three biologic agents (Adalimumab, Ustekinumab, Secukinumab) were recommended as first-line biologic agents for adults with psoriasis.

CONCLUSION

The overall methodological quality of CPGs for psoriasis is medium to high. More attention should be paid to applicability in guideline development. The recommendations and the basis for them among various sets guidelines were almost consistent.

Long-term effectiveness and safety of infliximab, golimumab and ustekinumab in patients with psoriatic arthritis from a Canadian prospective observational registry

OBJECTIVES

The objectives of this study were to describe the demographic profile and baseline disease characteristics of patients with psoriatic arthritis (PsA) treated with either infliximab (IFX), subcutaneous golimumab (GLM) or ustekinumab (UST) treatment in Canadian routine care setting along with assessing long-term effectiveness and safety.

METHODS

Patients with PsA were enrolled into the Biologic Treatment Registry Across Canada registry (ClinicalTrials.gov Identifier: NCT00741793) from 2005 to 2017. The study visits occurred at study enrolment (baseline) and every 6 months thereafter. Effectiveness was assessed by changes in disease parameters (joint counts, Psoriasis Area Severity Index (PASI), Health Assessment Questionnaire, patient/physician global, minimal disease activity, enthesitis, dactylitis, erythrocyte sedimentation rate, C reactive protein). Improvements from baseline were explored with the paired t-test and the McNemar's test. Safety was evaluated by assessing the incidence of adverse events (AEs) and drug survival rates.

RESULTS

A total of 111 IFX-treated, 281 GLM-treated and 70 UST-treated patients were enrolled. Most baseline disease parameters remained similar over time in all three cohorts. UST-treated patients had lower mean baseline Disease Activity Score in 28 joints CRP, swollen joint based on 28 joints and higher PASI compared with patients treated with GLM. Treatment with IFX, GLM and UST was associated with significant improvements in all disease parameters over time (p<0.001) from baseline up to 84, 84 and 40 months, respectively.AEs were reported for 74.8%, 69.8% and 52.9% (138, 114 and 115 events/100 patient-years (PYs)) covering 325, 567 and 87 years of exposure for IFX-treated, GLM-treated and UST-treated patients, respectively. Severe AEs were reported in 19.8%, 8.5% and 5.7% (8.8, 7.2 and 8.0 events/100 PYs) in IFX-treated, GLM-treated and UST-treated patients, respectively. The proportion of patients who discontinued treatment were 63.1%, 50.9% and 50.0%, respectively.

CONCLUSIONS

IFX, GLM and UST treatment significantly reduced disease activity and improved functionality in patients with PsA followed by routine clinical practice and had a safety profile similar to that previously reported in the literature.

Baseline Characteristics of Patients with Ankylosing Spondylitis and Psoriatic Arthritis Treated with Secukinumab in the Real-World Setting: AQUILA, a Non-Interventional Study

Objective:

AQUILA is an ongoing, multicenter, prospective, Non-Interventional Study (NIS) with secukinumab, designed to evaluate real-world evidence for different aspects of treatment in patients with Ankylosing Spondylitis (AS) and psoriatic arthritis (PsA) in Germany. Here we report the study design and baseline characteristics including comorbidities and prior medication of patients as well as insights into medical care in Germany.

Methods:

Patients (age ≥18 years) with active AS or PsA, who were under secukinumab treatment or just about initiating secukinumab therapy based on medical therapeutic need, are enrolled. Each patient is observed for 52 weeks.

Results:

A total of 572 patients (AS, n = 187; PsA, n = 385) have been recruited in this ongoing study. Mean age, weight, and BMI were similar between the subgroups. About 66.4% of patients had previously received biologics other than secukinumab. Depression was the most common comorbidity (AS, 9.1%; PsA, 15.6%). Plaque psoriasis was also frequently reported (AS, 9.6%; PsA, 62.3%).

Conclusion:

The Non-Interventional Study (NIS) baseline characteristics indicate that the demographics were similar to populations of previous secukinumab trials of AS and PsA patients except to comorbidities and exposure to biologics. A majority of the patients who received secukinumab in this setting had previously received biologics. Comorbidities relating to obesity and cardiovascular disease were particularly evident in PsA patients whereas the elevated depression prevalence was equally distributed.

Medication persistence for psoriatic arthritis in a Brazilian real-world setting

Aim:

To evaluate the persistence of biological (TNF inhibitor [anti-TNF]) and synthetic (conventional synthetic disease-modifying antirheumatic drugs [csDMARDs]) antirheumatic agents for psoriatic arthritis and their associated factors.

Methods:

A historical cohort was developed. Persistence and associated factors were evaluated at 6 and 12 months.

Results:

A total of 161 patients were included. The anti-TNF treatment presented higher persistence as compared with csDMARDs at 6 (83.4 vs 50.8%; p < 0.05) and 12 months (66.4 vs 35.6%; p < 0.05). From anti-TNFs, adalimumab and etanercept presented similar persistence, along with leflunomide and methotrexate among the csDMARDs. The factors associated with non-persistence with regard to anti-TNF agents were female sex and use of infliximab.

Conclusion:

Anti-TNF agents are important therapeutic alternatives and present lower rates of discontinuation as compared with csDMARDs.

Conventional synthetic disease-modifying antirheumatic drugs (csDMARD) and anti-TNF agents were included in the Brazilian National Health System in 2009, yet were not previously the target of evaluations in a Brazilian context. Persistence, that is the time between starting and discontinuing the drug, is a proxy of effectiveness and safety for antirheumatic agents. This study evaluated medication persistence and relevant factors associated with it. Patients using infliximab showed a lower medication persistence when compared with adalimumab and etanercept. The medication persistence with anti-TNF agents was higher when compared with csDMARDs. Female sex and infliximab were predictors of medication non-persistence.

Advances in rheumatology practice in Brazil

Despite resilient inequities, Brazil has seen progressive improvement in health care in the last 25 years. Infectious diseases rendered place to chronic non-communicable diseases as a major cause of death. Existence of traditional schools of medicine and training services in rheumatology helped form a reasonable number of specialists, though irregular distribution due to the economic issues favoring their clustering in major cities. The Brazilian Society of Rheumatology provides continued medical education, helps training rheumatologists, family physicians and other health professionals and has worked to publish national recommendations for the diagnosis and treatment of major rheumatic diseases. Access to medications and health care facilities is provided for most patients, free of direct charge, including biologics. Specialized services for autoimmune and rare diseases, including pediatric rheumatology and autoinflammatory diseases, have improved, particularly in developed centers of the southern best developed parts of the country. A major unmet need is the lack of access to non-pharmacological treatment modalities. In this article, we will summarize some of the strengths and points that need improvement to enhance access to the rheumatological health care in Brazil.

Effectiveness and safety of anti-TNF in psoriatic arthritis patients in Brazil: a post-incorporation analysis

AIM

Psoriatic arthritis is a chronic disease that can result in disability and decreased quality of life.

MATERIALS & METHODS

A prospective cohort was conducted in Brazil. Disease activity was measured by the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Clinical Disease Activity Index (CDAI), functionality by the Health Assessment Questionnaire Disability Index (HAQ-DI) and the quality of life by the EuroQol 5D (EQ-5D).

RESULTS

In total, 122 patients were included. After 6 months, a median reduction of 2.03 in the BASDAI, 7.80 in the CDAI, 0.63 in the HAQ-DI and increase of 0.12 in the EQ-5D was observed. A good clinical response was observed in 45.5% of the patients by BASDAI and 54.5% by CDAI. Higher education and better quality of life were identified as predictors of effectiveness. The most common side effects were the infections.

CONCLUSION

Anti-TNF-α drugs were effective and safe. The incorporation of them into the Brazilian Public Health System has provided therapeutic alternatives to the treatment of psoriatic arthritis.

Efficacy and safety of secukinumab administration by autoinjector in patients with psoriatic arthritis: results from a randomized, placebo-controlled trial (FUTURE 3)

BACKGROUND

The study aimed to assess 52-week efficacy and safety of secukinumab self-administration by autoinjector in patients with active psoriatic arthritis (PsA) in the FUTURE 3 study ( ClinicalTrials.gov NCT01989468).

METHODS

Patients (≥ 18 years of age; N = 414) with active PsA were randomized 1:1:1 to subcutaneous (s.c.) secukinumab 300 mg, 150 mg, or placebo at baseline, weeks 1, 2, 3, and 4, and every 4 weeks thereafter. Per clinical response, placebo-treated patients were re-randomized to s.c. secukinumab 300 or 150 mg at week 16 (nonresponders) or week 24 (responders) and stratified at randomization by prior anti-tumor necrosis factor (TNF) therapy (anti-TNF-naïve, 68.1%; intolerant/inadequate response (anti-TNF-IR), 31.9%). The primary endpoint was the proportion of patients achieving at least 20% improvement in American College of Rheumatology response criteria (ACR20) at week 24. Autoinjector usability was evaluated by Self-Injection Assessment Questionnaire (SIAQ).

RESULTS

Overall, 92.1% (300 mg), 91.3% (150 mg), and 93.4% (placebo) of patients completed 24 weeks, and 84.9% (300 mg) and 79.7% (150 mg) completed 52 weeks. In the overall population (combined anti-TNF-naïve and anti-TNF-IR), ACR20 response rate at week 24 was significantly higher in secukinumab groups (300 mg, 48.2% (p < 0.0001); 150 mg, 42% (p < 0.0001); placebo, 16.1%) and was sustained through 52 weeks. SIAQ results showed that more than 93% of patients were satisfied/very satisfied with autoinjector usage. Secukinumab was well tolerated with no new or unexpected safety signals reported.

CONCLUSIONS

Secukinumab provided sustained improvements in signs and symptoms in active PsA patients through 52 weeks. High acceptability of autoinjector was observed. The safety profile was consistent with that reported previously.

Secukinumab sustains improvement in signs and symptoms of psoriatic arthritis: 2 year results from the phase 3 FUTURE 2 study

Objectives

To assess long-term efficacy, safety and tolerability of secukinumab up to 104 weeks in patients with active PsA.

Methods

Patients with PsA (n = 397) were randomized to s.c. secukinumab 300, 150 or 75 mg or placebo at baseline, weeks 1, 2, 3 and 4 and every 4 weeks thereafter. Placebo-treated patients were re-randomized to receive secukinumab 300 or 150 mg s.c. from week 16 (placebo non-responders) or week 24 (placebo responders). Exploratory endpoints at week 104 included 20, 50 and 70% improvement in ACR criteria (ACR20, 50, 70); 75 and 90% improvement in the Psoriasis Area Severity Index, 28-joint DAS with CRP, presence of dactylitis and enthesitis and other patient-reported outcomes. For binary variables, missing values were imputed; continuous variables were analysed by a mixed-effects model for repeated measures.

Results

A total of 86/100 (86%), 76/100 (76%) and 65/99 (66%) patients in the secukinumab 300, 150 and 75 mg groups, respectively, completed 104 weeks. At week 104, ACR20 response rates after multiple imputation in the 300, 150 and 75 mg groups were 69.4, 64.4 and 50.3%, respectively. Sustained clinical improvements were observed through week 104 with secukinumab across other clinically important domains of PsA. Responses were sustained through week 104 regardless of prior anti-TNF-α use. Over the entire treatment period the incidence, type and severity of adverse events were consistent with those reported previously.

Conclusion

Secukinumab provided sustained improvements in signs and symptoms and multiple clinical domains in patients of active PsA through 2 years of therapy. Secukinumab was well tolerated, with a safety profile consistent with that reported previously.
