Sensitivity and Specificity of Composite Indices of Remission in Male and Female Patients With Psoriatic Arthritis: A Multicenter Cross-Sectional Study of Longitudinal Cohorts.

OBJECTIVE: The aim was to evaluate the sex differences in sensitivity, specificity, positive and negative predictive values, and likelihood ratio of the outcome indices minimal disease activity (MDA), Disease Activity Score for Psoriatic Arthritis (DAPSA), and Psoriatic Arthritis Impact of Disease (PsAID) with respect to clinical remission, evaluated from both the physician and patient perspective, in a multicenter cohort of patients with PsA. METHODS: In this cross-sectional analysis of 2 longitudinal cohorts, all patients with PsA consecutively attending our rheumatology units were considered potentially eligible for the study. In all patients, a complete clinical examination was carried out. The DAPSA was calculated for each patient (DAPSA values ≤ 4 were considered as remission) and MDA was also evaluated. Patient and physician global assessment values ≤ 1 were considered as a surrogate of remission from the patient and physician perspective, respectively. RESULTS: Two hundred seventy-two patients with PsA were enrolled (mean age 55.7 [SD 12.4]; 141 male, 131 female). In both sexes, MDA had good sensitivity and specificity toward remission as assessed by the rheumatologist. Remission according to DAPSA had excellent values of specificity but lacks sensitivity in both sexes. PsAID ≤ 4 had excellent values of sensitivity but lacked specificity in both sexes. Remission defined by DAPSA values was found to be more sensitive and specific in female patients (45.4% and 100%, respectively) than in male patients (33.3% and 84.2%, respectively) with respect to physician-judged remission. CONCLUSION: The results of this study demonstrate for the first time, to our knowledge, that some differences between the 2 sexes on the different outcome indices are possible. This could be important in the clinical management of patients with PsA.

The assessment of the drug retention rate of secukinumab in patients with psoriatic arthritis in a real-life multicentre cohort.

OBJECTIVES: We aimed to evaluate the drug retention rate (DRR) of secukinumab, an anti-IL-17A monoclonal antibody, in patients with psoriatic arthritis (PsA) in a real-life cohort, and to assess the impact of comorbidities and patient clinical characteristics on the DRR of secukinumab. METHODS: A retrospective study of prospective followed-up patients was performed to evaluate the DRR of secukinumab on patients with PsA attending the recruiting centres between January 2016 and June 2022. RESULTS: In 207 patients with PsA, a 60-month DRR of secukinumab of 57.0% was estimated (mean time of administration of 21.5±17.1 months). Male gender, age ≥65 years, disease duration ≥5 years and ≥10 years did not influence the DRR of secukinumab. The presence of comorbidities, considering any concomitant disorder, did not affect the DRR of secukinumab. In patients with cardiometabolic multimorbidity, a trend toward a better DRR of secukinumab was recorded. In fact, patients with high blood pressure, dyslipidaemia, and type 2 diabetes showed a trend toward an improved DRR of secukinumab. Furthermore, the presence of obesity did not influence the DRR of secukinumab. Different dosages, previous bDMARDs, and concomitant therapy with csDMARDs did not influence the DRR of secukinumab. CONCLUSIONS: A cumulative 60-month DRR of secukinumab of 57.0% in patients with PsA was retrieved. The presence of cardiometabolic multimorbidity could be associated with an improved DRR of secukinumab, whereas obesity did not affect this feature in our cohort. Previous bDMARDs, concomitant csDMARDs, and different drug dosages could not influence the DRR of secukinumab over time.

Male Fertility in Spondyloarthritis: from Clinical Issues to Cytokines Milieu. A Narrative Review.

PURPOSEOF REVIEW: Male fertility is an emergent issue that should be considered in clinical practice, when dealing with chronic inflammatory diseases in young men. As it is known, the chronic inflammation is the main pathophysiologic mechanism in some rheumatological conditions such as spondyloarthritis (SpA), Ankylosing Spondylitis (AS) and Psoriatic Arthritis (PsA). Therefore, it is paramount to be aware if these diseases could impair male fertility, both due to the inflammation or to the treatments needed: we reviewed the literature on the most relevant and recent evidence on male fertility in patients affected by SpA, AS and PsA. RECENT FINDINGS: Rheumatological inflammatory diseases (included SpA, AS and PsA) could impair the family planning in man life, especially when diagnosed at young age. Moreover, focusing on sperm quality, it seems that a link between sperm quality impairment and a higher disease activity exist. Focusing on therapies, Tumor Necrosis Factor inhibitors showed a safety profile on human male fertility in clinical studies. Recently, a prospective study and two double-blind placebo-controlled trials assessed the impact of methotrexate and Filgotinib on semen parameters, respectively, showing a safety profile of these drugs on human semen quality. However, there are no clinical data on the impact of Interleukin (IL)17 inhibitors(i), IL12-23i and IL23i. Concerning male fertility in SpA, AS and PsA, an unmet clinical need is still present and new studies are needed to understand the association between these diseases and male fertility, and the implication of the therapies used for these diseases. This narrative review provides an overview of the available data on male fertility in patients affected by SpA, AS and PsA.

Cardiovascular comorbidities in psoriatic arthritis: epidemiology and risk factors in two different European populations.

OBJECTIVES: Psoriatic arthritis (PsA) is a chronic inflammatory disease, frequently associated with cardiovascular (CV) comorbidities. Our aim was to compare the prevalence of CV comorbidities between two groups of PsA patients from different European countries: Belgium and Italy. METHODS: This is a cross-sectional analysis of two longitudinal cohorts in which 803 PsA patients were enrolled (463 from Belgium and 340 from Italy). All enrolled patients were ≥18 years old and fulfilled the ClASsification criteria for Psoriatic Arthritis (CASPAR criteria). For each patient, demographics, clinical assessments, smoking habits, the presence of arterial hypertension (AH), obesity (BMI ≥30), type 2 diabetes (T2D), CV diseases (acute myocardial infarction, stroke or transient ischaemic attack), dyslipidaemia (Italy only) and hypercholesterolaemia (Belgium only) were collected. RESULTS: The most prevalent comorbidities among Italian patients with PsA were: AH (45.1%), dyslipidaemia (38.6%) and obesity (30.8%), and among Belgian patients were: hypercholesterolaemia (30.9%), obesity (27%) and AH (26.4%). Moreover, the prevalence of T2D and CV diseases was respectively 14.2% and 7.1% among Italian patients and 7.6% and 3.5% among Belgian patients. When comparing the two groups, AH, T2D and CV diseases were significantly more prevalent in Italian PsA patients. After controlling for different confounders, Italian patients, regardless of age, sex, smoking habits, PsA duration, other CV comorbidities, therapy, disease activity and function, had a higher risk to be hypertensive (OR 2.00, p=0.007). Instead of the country in which patients lived was not a predictor for the risk of T2D and CV diseases. Obesity prevalence was not different between the two groups. The lipid profile was unfavourable in both populations (even if not comparable between the two groups, due to the different way of collection), as is often the case in PsA. CONCLUSIONS: The prevalence of AH, T2D and CV diseases were higher in Italian patients rather than Belgians. Moreover, among patients with PsA, the risk of AH was higher in the Italian cohort compared to the Belgian cohort. These results suggest that further research is needed to evaluate potential extrinsic factors (geography and sociocultural aspects) that may contribute to CV risk.

Impact of Physical Activity on Disability Risk in Elderly Patients Hospitalized for Mild Acute Diverticulitis and Diverticular Bleeding Undergone Conservative Management.

Background and Objectives: The role of physical activity (PA) in elderly patients admitted to surgical units for mild acute diverticulitis in the development of disability has not been clarified so far. Our aim is to demonstrate the relationship between physical activity and better post-discharge outcomes on disability in elderly population affected by diverticular disease. Materials and Methods: We retrospectively reviewed data of 56 patients (32 Males-24 females) collected from October 2018 and March 2020 at Cardarelli Hospital in Campobasso. We included patients older than 65 yrs admitted for acute bleeding and acute diverticulitis stage ≤II, characterized by a good independence status, without cognitive impairment and low risk of immobilization, as evaluated by activity of daily living (ADL) and the instrumental activity of daily living (IADL) and Exton-Smith Scale. "Physical Activity Scale for the Elderly" (PASE) Score evaluated PA prior to admission and at first check up visit. Results: 30.4% of patients presented a good PA, 46.4% showed moderate PA and 23.2% a low PA score. A progressive reduction in ADL and IADL score was associated with lower physical activity (p value = 0.0038 and 0.0017). We consider cognitive performance reduction with a cut off of loss of more than 5 points in Short Port of ADL and IADL and a loss of more than 15 points on Exton-Smith Scale, (p-value 0.017 and 0.010). In the logistic regression analysis, which evaluated the independent role of PASE in disability development, statistical significance was not reached, showing an Odds Ratio of 0.51 95% CI 0.25-1.03 p value 0.062. Discussion: Reduced physical activity in everyday life in elderly is associated with increased post-hospitalization disability regarding independence, cognitive performance and immobilization. Conclusions: Poor physical performance diagnosis may allow to perform a standardized multidimensional protocol to improve PA to reduce disability incidence.

Assessment of bone morphogenic protein 2 and interleukin-17A in patients with axial spondyloarthritis and their potential role in the new bone formation: a cross-sectional study.

OBJECTIVES: Several molecules are involved in the pathogenesis of new bone formation in axial spondyloarthritis (axSpA). The aim of this study was to evaluate the serum levels of BMP-2 and IL-17A in patients with axSpA and their possible correlations with radiographic damage, disease activity, and function. METHODS: AxSpA patients fulfilled the ASAS criteria and with at least New York grade 2 bilateral sacroiliitis and healthy matched controls were enrolled for this study. BASDAI, ASDAS-CRP, BASMI, BASFI and CRP were evaluated as measures of disease activity and function. Spinal damage was assessed using the mSASSS on radiographs performed within 3 months from baseline. Serum concentrations of BMP-2 and IL-17A were assessed using ELISA kit. RESULTS: Sixty patients and 30 healthy subjects satisfying the inclusion criteria were enrolled. In our axSpA group, serum BMP-2 levels [median (25th-75th percentile) of 589.2 (430.24-1017.1) pg/ml] did not statistically differ from controls [518.34 (450.2-1028.2) pg/ml]. However, significant correlations were found between serum BMP-2 levels and radiographic damage assessed by mSASSS, and BMP-2 levels were found to be higher in patients with grade 4 sacroiliitis when compared to patients with lower grade of sacroiliitis. Of note, serum BMP-2 levels significantly inversely correlate with IL-17A levels and CRP, and were found to be lower in patients with higher disease activity. CONCLUSIONS: The results of our study may confirm a possible role of BMP-2 in the pathogenesis of new bone formation in axSpA patients. Furthermore, a link between inflammation and BMP-2 was found.

Validation of the Italian version of proposed GRAPPA flare questionnaire for patients with psoriatic arthritis.

OBJECTIVES: The aim of the present study was to validate an Italian version of the GRAPPA flare instrument to identify patients with psoriatic arthritis (PsA) with a possible disease flare. METHODS: This was a cross-sectional study enrolling consecutively PsA patients classified with CASPAR criteria. Inclusion criteria were: age ≥18 years and stable treatment (at least six months of follow-up) with conventional synthetic or biological DMARDs. The flare questionnaire was administered at baseline and within a two-week interval. Internal consistency of the questionnaire was evaluated with Cronbach's alpha coefficient. Construct validity of flare questionnaire was assessed using the correlation between flare score and disease activity indices, HAQ and serum C-reactive protein. Cohen's κ was performed to assess the agreement level between the patient's perception of flare and the score of the questionnaire. Finally, test-retest was performed to assess the reliability of the instrument. RESULTS: 46 PsA patients were enrolled in this study. Of these, 30.4% reported a status of flare of their disease. The questionnaire was internally consistent (alpha=0.81). Moreover, the questionnaire score correlated with the main disease activity indices (Spearman Rho ranging from 0.30 to 0.66; p<0.01). The score of flare questionnaire showed a moderate agreement with the perception of flare from the patients (Cohen's κ=0.54). Test-retest reliability showed a good intra-class correlation. CONCLUSIONS: This initial validation of the Italian version of the GRAPPA flare instrument was favourable. Our results confirm the utility of this questionnaire in the assessment of flare in PsA.

Assessment of semaphorin 3A and its role in bone remodelling in a group of ankylosing spondylitis patients.

OBJECTIVES: Several molecules are involved in the pathogenesis of new bone formation in ankylosing spondylitis (AS). The aim of the present study was to evaluate serum levels of semaphoring 3A in AS and to investigate any correlations with radiographic damage, disease activity, function and treatment. METHODS: AS patients who fulfilled the modified New York criteria were enrolled for this study. Healthy subjects were also enrolled as control group. BASDAI, ASDAS-CRP, BASMI, BASFI, patients and physician VAS, C-reactive protein and erythrocyte sedimentation rate were evaluated at baseline visit. Radiographs of the spine and pelvis performed within six months from the enrolment in the study were collected in all patients. Spinal damage was assessed using the mSASSS. Serum concentrations of semaphorin3A were assessed at baseline and after four months of therapy in patients who started an anti-TNF. RESULTS: Twenty healthy subjects and forty AS patients were enrolled in the study. Of these patients, 15 started anti-TNF therapy the day of baseline visit. Semaphorin3A serum concentrations [median (25th-75th)] were similar in AS patients [0.26 (0.20-0.31) ng/ml] and controls [0.28 (0.26-0.3) ng/ml; p=ns). No significant correlation was found between semaphorin 3A serum levels and radiographic damage index. Semaphorin 3A serum levels positively correlated with ESR values (rho=0.37, p=0.049) and with disease activity assessed by the physician VAS (rho=0.47, p<0.01). No differences were found in the semaphorin3A serum levels after 4 months, compared to baseline values. CONCLUSIONS: The results of the present study could contribute to the intriguing topic of bone remodelling in AS.

An ultrasonographic study of enthesis in early psoriatic arthritis patients naive to traditional and biologic DMARDs treatment.

The aim of this study was to evaluate the rate of power Doppler ultrasound (PDUS) abnormalities at entheseal sites in patients with early psoriatic arthritis (PsA) naïve to traditional and biologic DMARDs and to compare the PDUS findings with clinical examination. PsA patients with early disease and naïve to traditional and biologic DMARDs were consecutively enrolled in this study. Patients underwent PDUS examination of the following bilateral entheseal sites: common extensor tendon at its insertion at the lateral humeral epicondyle; quadriceps tendon at its insertion at the superior pole of the patella; patellar tendon at its insertion at the tibial tuberosity; medial collateral ligament at its proximal insertion and Achilles tendon at its insertion at the calcaneus. The Leeds enthesitis index (LEI) was used to assess clinical entheseal involvement. Twenty-one early PsA patients completed the clinical and PDUS examinations. Clinical entheseal involvement was found in 9 (42.9 %) and PDUS abnormalities in 20 (95.5 %) of the 21 early PsA patients. Achilles tendon insertion was the site with the major entheseal abnormalities. Active (power Doppler positive) entheseal lesions were found in 4.7, 9.5, 14.3 and 14.3 % of patients at the lateral humeral epicondyle; quadriceps tendon, patellar tendon insertions, and Achilles tendon insertions, respectively. Concordance between clinical (LEI) and PDUS was poor. The present study confirms that PDUS allows detecting structural and inflammatory abnormalities of enthesis in early PsA patients. Our study shows that, in early disease, active abnormalities seem to have a low prevalence.

An overview of low disease activity and remission in psoriatic arthritis.

Psoriatic arthritis (PsA) is a complex, multisystem and potentially disabling disease with musculoskeletal and skin manifestations. In PsA, as well as in the other chronic rheumatic conditions, a state of low disease activity or remission should be the target of treatment but to reach this objective, in the assessment of PsA patients, is still an unmet need due to the heterogeneity of disease manifestations. With the introduction of anti-TNF treatment, low disease activity or remission become an achievable and suitable state that could be reached by 50%-60% of PsA patients. The aim of this paper is to briefly summarise the concept of low disease activity and remission in PsA, with particular focus on anti-TNF therapy.

Clinical Characteristics of "Severe" Peripheral Psoriatic Arthritis: A Retrospective Analysis of a Longitudinal Cohort.

INTRODUCTION: The concept of severity in a multidomain disease such as psoriatic arthritis (PsA) is still not well defined. The aim of this study was to identify the clinical characteristics of patients with severe peripheral PsA. METHODS: Retrospective analysis of a longitudinal cohort. Demographic and clinical characteristics of patients with PsA were collected at baseline and at last follow-up. We defined the severe population using the modified Composite Psoriatic Disease Activity Index (mCPDAI); which excludes ankylosing spondylitis quality of life scale). Hence, patients with a score of 3 in at least one domain were defined as having severe PsA. Clinical characteristics of patients fulfilling the definition of severe PsA were compared to those non-severe. RESULTS: We evaluated 177 patients with peripheral PsA (M/F: 98/76). Of these, 64 (36.1%) were identified as severe according to the mCPDAI criteria, at baseline. Eighteen patients (10.1%) at last follow-up still met the definition of severe PsA. At last follow-up visit, severe patients with PsA were only males (18/18, P < 0.01) and have worse outcomes in terms of disease activity, pain, function, and impact of disease. Male sex and the severity of skin involvement at baseline were factors associated with the presence of severe PsA. The agreement between the presence of severe PsA and the absence of minimal disease activity was slight [Cohen's k: 0.174 (0.084-0.264)]. CONCLUSIONS: Our study showed that severe patients with PsA had more disease activity, pain, and impact of disease than non-severe patients. Furthermore, we demonstrated that severity and disease activity are not interchangeable concepts.

Assessment of Patient-Physician Interactions in Psoriatic Arthritis: National Results of the ASSIST Study.

INTRODUCTION: An overarching principle for the management of psoriatic arthritis (PsA) is a shared decision-making process between physicians and patients. The aim of this study is to assess the patient-physician relationship in a group of patients with PsA, by using the Perceived Efficacy in Patient-Physician Interactions (PEPPI) and CollaboRATE instruments. METHODS: This is a cross-sectional multicenter study where consecutive patients with PsA were enrolled. For each patient, the main demographic, comorbid conditions, and clinical data were collected, including the assessment of disease activity, function, quality of life, and impact of disease. PEPPI and CollaboRATE questionnaires were used, respectively, to evaluate the patient's perception of the patient-physician relationship and the shared decision-making process. RESULTS: A total of 81 patients with PsA were enrolled at four centers in Italy. Overall, our patients showed a high level of confidence in obtaining needed health care, with relatively high median (IQR) values of PEPPI (20; 16-23), and a good shared decision-making process, with high median (IQR) values of CollaboRATE questionnaire (7; 6-9). PEPPI and CollaboRATE scores showed a statistically significant inverse correlation with different clinical variables such as disease duration, Leeds Enthesitis Index, PsA impact of Disease, Health Assessment Questionnaire, pain, patient's global assessment of disease activity and clinical disease activity for PsA. The presence of comorbidities did not appear to be associated with lower values of PEPPI and CollaboRATE. CONCLUSIONS: In this study, few patients with PsA were at risk of suboptimal communication with their physician. This phenomenon appeared to be primarily related to higher disease activity and burden.

Remission in ankylosing spondylitis treated with anti-TNF-α drugs: a national multicentre study.

OBJECTIVE: The primary objective of this retrospective study was to investigate the possibility of achieving partial remission (PR) in AS patients treated with anti-TNF-α antagonists, such as adalimumab (ADA), etanercept (ETA) and infliximab (INF), in a real clinical practice setting. Predictors of PR were also evaluated. METHODS: A retrospective study was conducted in patients with AS treated with ADA, ETA and INF from 2000 to 2012. Kaplan-Meier survival curves were plotted to determine the rates of PR during the treatment with anti-TNF-α drugs. RESULTS: A total of 283 patients with AS were treated with ADA (18.7%), ETA (26.8%) and INF (54.4%) as first anti-TNF-α drugs, with a PR rate of 57.6%. The probability of obtaining PR with ADA, ETA or INF was not significantly different among all anti-TNF-α patients. AS patients treated with a second anti-TNF-α drug had a PR rate of 40.5%, but after switching for lack of response, the probability of obtaining PR with a second anti-TNF-α drug was significantly lower from that of the first anti-TNF-α drug (P = 0.0039). The probability of obtaining PR in patients with enthesitis (P = 0.04) or psoriasis (P = 0.0016) or low levels of CRP (P = 0.0225) was significantly lower compared with that of patients without these manifestations at baseline. CONCLUSION: Our real-life study on PR confirmed the effectiveness of ADA, ETA or INF as first or second anti-TNF-α drugs. The presence at baseline of enthesitis or psoriasis or low CRP values yielded a lower probability of obtaining PR.

Difficult to Treat and Refractory to Treatment in Psoriatic Arthritis.

Psoriatic arthritis (PsA) is a complex and chronic inflammatory condition in which the achievement of the best possible disease control has been proposed as the treatment target, which includes the possibility of reaching remission in all disease domains. However, due to the complexity of this multidomain disease, some patients may still have high disease activity in one or more domain and a high burden of disease, potentially leading to various treatment changes and to difficulty with the overall management. In this paper, we overview the concept of patients with difficult-to-treat PsA and the concept of patients with refractory-to-treatment PsA by providing a distinction between these two concepts and the possible implication for the management of patients with PsA.

Ultrasonographic Evaluation of Entheseal Fibrocartilage in Patients with Psoriatic Arthritis, Athletes and Healthy Controls: A Comparison Study.

The aims of this study were as follows: (1) To evaluate the entheseal fibrocartilage (EF) during Achilles tendon insertion in patients with Psoriatic Arthritis (PsA) by using power Doppler ultrasound (PDUS), (2) to assess the intra and inter-reader reliability of the evaluation of EF thickness, (3) to compare the EF thickness of PsA patients, athletes and healthy controls (HCs), and (4) to evaluate the correlations between EF abnormalities, disease activity and functional indices in PsA. METHODS: Consecutive PsA patients attending our unit were asked to participate. HCs and agonist athletes were enrolled as a control group. A bilateral PDUS evaluation of Achilles tendons was performed in order to evaluate the EF in all patients and controls. RESULTS: In total, 30 PsA patients, 40 athletes and 20 HCs were enrolled. The median (IQR) EF thickness among the PsA patients, athletes and HCs was 0.035 cm (0.028-0.04) cm, 0.036 (0.025-0.043) cm and 0.030 (0.020-0.038) cm, respectively (p = 0.05 between PsA patients and HCs). The intra-reader reliability was excellent [ICC (95% CI) of 0.91 (0.88-0.95)] and the inter-reader reliability was good (0.80 (0.71-0.86). The assessment of EF was feasible, with a mean time of 2 min. No correlations were found with disease activity indices in PsA patients. CONCLUSION: The assessment of EF is a feasible and reproducible test and may be explored as a potential imaging biomarker.

Psoriatic Arthritis in Males and Females: Differences and Similarities.

OBJECTIVE: To assess any differences and similarities in psoriatic arthritis (PsA) between sexes. Any possible differences of psoriasis and its potential impact on disease burden between sexes with PsA were also evaluated. METHODS: Cross-sectional analysis of two longitudinal PsA cohorts. The impact of psoriasis on the PtGA was evaluated. Patients were stratified in four groups based on BSA. The median PtGA was then compared between the four groups. Moreover, a multivariate linear regression analysis was performed in order to evaluate associations between PtGA and skin involvement, split by sexes. RESULTS: We enrolled 141 males and 131 females: PtGA, PtPnV, tender, swollen joint count, DAPSA, HAQ-DI, PsAID-12 were statistically significant higher in females (p ≤ 0.05). PASS "yes" was deemed more in males than in females and BSA was higher in males. MDA was present more in males than females. When the patients were stratified on BSA, median PtGA was not different between males and females with BSA = 0. Instead, in females with BSA > 0, a higher PtGA was observed compared to males with BSA > 0. There was not a statistically significant association between skin involvement and PtGA at linear regression analysis, even if a trend seems to be present in female. CONCLUSIONS: Psoriasis is more present in males, but it seems to be related to a worse impact in females. In particular, a possible role of psoriasis as an influencing factor the PtGA was found. Moreover, female PsA patients tended to have more disease activity, worse function, and higher disease burden.

Triple jump for the optimal management of psoriatic arthritis: diet, sleep and exercise - a review.

Psoriatic arthritis (PsA) is a complex, multiform and chronic inflammatory disease characterised by the association of arthritis and psoriasis combined with other related conditions and comorbidities. Treatment of PsA has rapidly evolved by the introduction of new biological drugs and small molecules which allow to achieve disease remission or low disease activity in most of the patients. However, unmet treatment needs still persist for those patients with persistent disease activity or symptoms, impaired function, reduced quality of life or comorbidities. In this context, non-pharmacological approaches, including diet modifications, an adequate sleep quality and physical activity could provide additional benefits. In recent years, diet modifications, improvement of sleep quality and physical activity became an area of interest for researchers and some studies showed how a holistic non-pharmacological approach may ameliorate the quality of life of patients with PsA.The aim of this manuscript was to review the current evidence on the intriguing link and potential effects of diet, sleep and exercise in PsA patients. In particular, we reviewed the literature focusing on the possible benefits of a holistic approach to PsA patients considering lifestyle modifications.

Identification of the Minimal Disease Activity Domains Achieved Based on Different Treatments in Psoriatic Arthritis.

INTRODUCTION: The aim of this work is to characterize which Minimal Disease Activity (MDA) domains are mainly achieved, based on different treatments, in psoriatic arthritis (PsA) patients. Moreover, the association between MDA achievement and the different treatment groups was assessed. METHODS: We conducted a cross-sectional analysis of two longitudinal PsA groups. Inclusion criteria were: age ≥ 18 years, PsA diagnosis, stable treatment for at least 6 months. Patients were grouped depending on the therapy: group 1: Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)/cyclooxygenase 2 inhibitors (COX2i)/steroids, group 2: conventional synthetic Disease-Modifying Anti-Rheumatic Drugs (csDMARDs), group 3: Tumor Necrosis Factor α  inhibitors (TNFi), group 4: interleukin inhibitors (IL)12-23i or IL-23i, group 5: IL-17i, group 6: phosphodiesterase 4 inhibitors (PD4i). For each group, the achieved domains based on therapy were assessed. Multivariate logistic regression analysis was performed to assess the association between the treatment groups and the MDA achievement. RESULTS: A total of 220 patients were enrolled, and MDA was achieved in 45.8% of them. In all treatment groups, the first MDA domains achieved were: body surface area ≤ 3, swollen joint count ≤ 1 and Leeds Enthesitis Index ≤ 1, while MDA domains less frequently achieved were Patient Global Assessment (PtgA) ≤ 2 cm and pain on visual analogue scale ≤ 1.5 cm. The logistic regression analysis showed higher odds ratios for the achievement of the MDA in those patients in groups 3 and 4. CONCLUSIONS: In each treatment group, MDA domains less frequently achieved were PtGA and pain, suggesting that "patient-driven domains" are still an unmet need. Due to the study design and the low number of patients in some groups, it is not possible to clearly define which MDA domain was achieved or not based on treatment; however, it seems that some differences could be present. If larger and prospective studies confirm our preliminary results, we could move toward a personalized/domain treatment approach in PsA.
