RESUMO
OBJECTIVE: Our objective was to test the hypothesis, in a double-blind, placebo-controlled study that vipoglanstat, an inhibitor of microsomal prostaglandin E synthase-1 (mPGES-1) which decreases prostaglandin E2 (PGE2) and increases prostacyclin biosynthesis, improves RP. METHODS: Patients with systemic sclerosis (SSc) and ≥7 RP attacks during the last screening week prior to a baseline visit were randomised to four weeks treatment with vipoglanstat 120 mg or placebo. A daily electronic diary captured RP attacks (duration and pain) and Raynaud's Condition Score, with change in RP attacks/week as primary end point. Cold challenge assessments were performed at baseline and end of treatment. Exploratory endpoints included patients' and physicians' global impression of change, Assessment of Scleroderma-associated Raynaud's Phenomenon questionnaire, mPGES-1 activity, and urinary excretion of arachidonic acid metabolites. RESULTS: Sixty-nine subjects received vipoglanstat (n = 33) or placebo (n = 36). Mean weekly number of RP attacks (baseline; vipoglanstat 14.4[SD 6.7], placebo 18.2[12.6]) decreased by 3.4[95% CI -5.8;-1.0] and 4.2[-6.5;-2.0] attacks per week (p= 0.628) respectively. All patient reported outcomes improved, with no difference between the groups. Mean change in recovery of peripheral blood flow after cold challenge did not differ between the study groups. Vipoglanstat fully inhibited mPGES-1, resulting in 57% reduction of PGE2 and 50% increase of prostacyclin metabolites in urine. Vipoglanstat was safe and well tolerated. CONCLUSION: Although vipoglanstat was safe, and well tolerated in a dose achieving full inhibition of mPGES-1, it was ineffective in SSc-related RP. Further development and evaluation of vipoglanstat will therefore be in other diseases where mPGES-1 plays a pathogenetic role.
RESUMO
Pain is a crucial factor in rheumatic disorders, and reducing it is a primary goal of successful treatment. Adaptive pain-coping strategies can enhance this improvement, but maladaptive approaches such as pain catastrophizing may worsen overall patient well-being. This narrative review aims to provide a concise overview of the existing knowledge on pain catastrophizing in the most prevalent specific rheumatic disorders. The objective of this study was to improve understanding of this phenomenon and its implications, as well as to pinpoint potential directions for future research. We conducted searches in the MEDLINE/PubMed, SCOPUS, and DOAJ bibliography databases to identify articles related to pain catastrophizing in rheumatoid arthritis, psoriatic arthritis, axial spondylarthritis, systemic sclerosis, systemic lupus erythematosus, Sjögren's syndrome, juvenile idiopathic arthritis, and osteoarthritis (non-surgical treatment). Data extraction was performed on November 1, 2023. The investigators screened the identified articles to determine their relevance and whether they met the inclusion criteria. Following a bibliography search, which was further expanded by screening of citations and references, we included 156 records in the current review. The full-text analysis centred on pain catastrophizing, encompassing its prevalence, pathogenesis, and impact. The review established the role of catastrophizing in amplifying pain and diminishing various aspects of general well-being. Also, potential treatment approaches were discussed and summarised across the examined disorders. Pain catastrophizing is as a significant factor in rheumatic disorders. Its impact warrants further exploration through prospective controlled trials to enhance global patient outcomes.

OBJECTIVE: Randomized controlled trials are considered the gold standard in study methodology. However, due to their study design and inclusion criteria, these studies may not capture the heterogeneity of real-world patient populations. In contrast, the lack of randomization and the presence of both measured and unmeasured confounding factors could bias the estimated treatment effect when using observational data. While causal inference methods allow for the estimation of treatment effects, their mathematical complexity may hinder their application in clinical research. METHODS: We present a practical, nontechnical guide using a common statistical package (Stata) and a motivational simulated dataset that mirrors real-world observational data from patients with rheumatic diseases. We demonstrate regression analysis, regression adjustment, inverse-probability weighting, propensity score (PS) matching and two robust estimation methods. RESULTS: Although the methods applied to control for confounding factors produced similar results, the commonly used one-to-one PS matching method could yield biased results if not thoroughly assessed. CONCLUSION: The guide we propose aims to facilitate the use of readily available methods in a common statistical package. It may contribute to robust and transparent epidemiological and statistical methods, thereby enhancing effectiveness research using observational data in rheumatology.

Diagnosis and effective treatment of axial spondyloarthritis (AxSpA) are often delayed due to inadequate awareness and poor patient-physician communication. Some AxSpA patients fail to maintain an active lifestyle by exercising regularly, further worsening their disease management. The evolving concept of patient-centred care necessitates better understanding of patient awareness and their needs. We aimed to survey AxSpA patients to reflect on healthcare planning and management perspectives. Our self-administered questionnaire focused on perceptions of AxSpA diagnosis and management, particularly exploring issues of physical activity and active lifestyle. Satisfaction with AxSpA medical care and its accessibility, diagnostic delays, patient-physician communication, and support for disease management were also explored. This offline survey was arranged at the Department of Rheumatology, Immunology, and Internal Medicine of Jagiellonian University Medical College and Krakow University Hospital. We surveyed patients with AxSpA attending outpatient clinics between December 1st, 2023 and April 22nd, 2024. The questionnaire included questions on types of physical activities, barriers to exercising, satisfaction with medical care, patient-physician interactions, diagnostic delays, and use of teleconsultations. A total of 117 patients with AxSpA were enrolled (mean age 41.62 years). The majority (n = 93, 79.5%) were employed. There was a male predominance (69, 59%). The average diagnostic delay was 5.5 years. Notably, 104 (88.9%) responders perceived physical activity as a factor influencing their disease course. However, only 32 (27.35%) managed to exercise regularly (≥ 30 min, 2-3 times a week). The majority (70, 59.83%) were irregularly engaged in some form of physical activity, with 15 (12.8%) not exercising at all, and nearly half (48%) reported at least one barrier to maintaining a physically active lifestyle. Pain (32, 27.35%), fatigue (27, 23.08%), lack of motivation (17, 14.53%), and lack of time (12, 10.26%) were noted as barriers to exercising. The respondents preferred to exercise at home. The survey identified critical areas where patient dissatisfaction or uncertainty were notably prevalent: 38 (32.5%) were uncertain and 35 (30%) were dissatisfied with rehabilitation access. For spa therapy, 63 (53.85%) reported uncertainty and 23 (19.7%) expressed dissatisfaction. Only 48 (41%) were treated by a rehabilitation specialist last year. Only 23% of AxSpA patients took part in teleconsultations last year, and 65% preferred in-person visits. While AxSpA patients recognize the importance of physical activity, significant barriers exist to engaging them regularly in exercising. Addressing these barriers through personalized, motivational, and educational strategies could improve patient outcomes. Improving patient satisfaction with healthcare services, particularly in areas of rehabilitation and physician-patient communication, is crucial for improving the overall care of AxSpA patients.

Axial spondyloarthritis (axSpA) is a chronic condition predominantly affecting the spine and sacroiliac joints. This article provides an in-depth overview of the current approaches to diagnosing, monitoring, and managing axSpA, including insights into developing terminology and diagnostic difficulties. A substantial portion of the debate focuses on the challenging diagnostic procedure, noting the difficulty of detecting axSpA early, particularly before the appearance of radiologic structural changes. Despite normal laboratory parameters, more than half of axSpA patients experience symptoms. X-ray and magnetic resonance imaging (MRI) are essential for evaluating structural damage and inflammation. MRI can be beneficial when there is no visible structural damage on X-ray as it can help unravel bone marrow edema (BME) as a sign of ongoing inflammation. The management covers both non-pharmacological and pharmacological approaches. Lifestyle modifications, physical activity, and patient education are essential components of the management. Pharmacological therapy, including nonsteroidal anti-inflammatory drugs (NSAIDs) and biologic disease-modifying anti-rheumatic drugs (bDMARDs), are explored, emphasizing individualized treatment. To effectively manage axSpA, a comprehensive and well-coordinated approach is necessary, emphasizing the significance of a multidisciplinary team. Telehealth applications play a growing role in axSpA management, notably in reducing diagnostic delays and facilitating remote monitoring. In conclusion, this article underlines diagnostic complexities and emphasizes the changing strategy of axSpA treatment. The nuanced understanding offered here is designed to guide clinicians, researchers, and healthcare providers toward a more comprehensive approach to axSpA diagnosis and care.

Psoriatic arthritis (PsA) carries a severe disease burden, often leading to deterioration of health-related quality of life (HRQoL). Different comorbidities that are relatively prevalent in PsA are also responsible for compromised HRQoL. To assess real-world data of a 5-year follow-up cohort of PsA patients, focusing on changes in general HRQoL, skin HRQoL, and comorbidities. In this prospective observational study, 114 outpatients diagnosed with PsA were examined at baseline and after 5 years. Data collection included demographics, clinical disease activity measures, and patient-reported outcome measures (PROMs). General HRQoL was assessed with a 15D instrument, and skin HRQoL was assessed with the Dermatology Life Quality Index (DLQI). During the 5-year follow-up, no significant deterioration in HRQoL assessed by 15D (23.53 vs. 23.08, p = 0.85) and DLQI (3.48 vs. 2.68, p = 0.07) was observed. There was no observed decline in other PROMs. The mean total number of comorbidities increased (1.13 vs. 1.39, p < 0.01). A significant improvement in disease activity measures, including 66/68 swollen/tender joint count, Disease Activity Index for Psoriatic Arthritis (all p < 0.01), and Psoriatic Arthritis Severity Index (p = 0.04) was seen. A higher proportion of patients at 5 years were treated with b/tsDMARDs (37.7% vs. 46.5%, p = 0.03). Despite an increased number of comorbidities over 5 years, our PsA cohort showed no decline in HRQoL. This can be attributed to the widespread adoption of modern treatments, leading to improved disease control and the preservation of baseline HRQoL.

Endothelial dysfunction (ED) is defined as an impairment in the vasodilatory, anti-thrombotic, and anti-inflammatory properties of the cells that make up the lining of blood vessels. ED is considered a key step in the development of atherosclerotic cardiovascular disease. The association between ED and systemic inflammatory diseases is well established. However, the prevalence and clinical significance of ED in psoriatic arthritis (PsA) have been investigated to a lesser extent. This review aims to explore the link between ED and PsA, including ED in macro- and microcirculation, as well as risk factors for its occurrence in PsA and its relationship with atherosclerosis in PsA. Furthermore, the ED in PsA was compared with that of rheumatoid arthritis (RA). Regarding ED in the microcirculation, the coronary flow reserve was found to be significantly reduced in individuals with PsA. The relationship between PsA and macrovascular ED is more pronounced, along with more advanced atherosclerosis detected in patients with PsA. These results are consistent with those obtained in RA studies. On the other hand, arterial stiffness and signs of vascular remodeling were found more frequently in RA than in PsA, with the potential role of efficient anti-TNF treatment in patients with PsA and psoriasis explaining this finding. The impact of ED on cardiovascular diseases and the burden of this risk caused independently by PsA have not yet been precisely established, however, this group of patients requires special attention with regard to cardiovascular events.
RESUMO
Spondyloarthritis (SpA) is a group of inflammatory disorders, including axial SpA (axSpA), characterized by inflammation in the spine and sacroiliac joints. Healthcare professionals have a crucial role in diagnosing and managing axSpA. Assessing their knowledge, perceptions, and practices is essential to enhance patient care. The objective of this study is to evaluate these factors by conducting an online survey. This online survey was performed using SurveyMonkey.com to assess healthcare professionals' knowledge, perceptions, and practices related to axSpA diagnosis, management, and monitoring. The questionnaire included questions about definitions, management strategies, monitoring approaches, treatment options, and barriers to care. Convenience sampling was used, and the data were analyzed descriptively by Microsoft Excel. One hundred sixty-four healthcare professionals participated; most respondents were rheumatologists from various geographic locations (27 countries). Most participants were familiar with axSpA definitions and diagnostic criteria, demonstrating high expertise. Variations were seen in follow-up intervals and diagnostic preferences, reflecting clinical heterogeneity. Seventy-two (43.9%) individuals had a multidisciplinary team, frequently including rheumatologists, physiotherapists, and radiologists. Of the participants, 73 (44.5%) had online/telephone follow-up sessions. The pharmacological and non-pharmacological treatment approaches varied, pointing to the importance of personalized care. Glucocorticoid use varied among countries. Recognizing inflammatory back pain, interpreting radiographs, and diagnosing early was essential to medical education. This study provides beneficial data on healthcare professionals' knowledge, perceptions, and practices regarding axSpA. While diagnostic familiarity and multidisciplinary approach are positives, there is a potential to standardize management, improve telemedicine services, remove barriers to physical activity, and optimize treatment options.

BACKGROUND: Comorbidities are frequent in psoriatic arthritis (PsA) and may contribute to worse health-related outcomes. Patient-reported outcomes (PROs) are used to evaluate the burden of the assessed disease. The aim of this study is to evaluate the impact of comorbidities on selected PROs in PsA. METHODS: Adult patients, diagnosed with PsA, based on CASPAR criteria, were included in this cross-sectional, observational study. Collected data encompassed the comorbidities and PROs (Health Assessment Questionnaire [HAQ], Multi-Dimensional Health Assessment Questionnaire [MDHAQ], 36-Item Short Form Health Survey [SF-36]). Standard statistic methods were performed for data assessment. RESULTS: There were 267 participants included in the study (54.7% females). The most prevalent comorbidities were cardiovascular diseases (CVD) (29.2 %). Multimorbidity was observed in 50.2% cases and was associated with poorer results of SF-36 questionnaire, regarding bodily pain (34.7 [30.1, 39.3] vs. 47.5 [43.1, 52.0]; p<0.01), physical functioning (52.1 [47.3, 56.9] vs. 63.1 [58.9, 67.4]; p<0.01) and role physical (28.5 [21.2, 35.9] vs. 42.8 [35.2, 50.4]; p<0.01). CVD were associated with poorer MDHAQFn score (ß=0.17, p<0.01), while mental disorders negatively influenced mental health (ß= -0.35, p<0.01), vitality (ß= -0.22, p<0.01), general health (ß= -0.19, p<0.01), social functioning (ß= -0.15, p=0.04) and role emotional (ß= -0.30, p<0.01) dimensions of SF-36. CONCLUSIONS: Multimorbidity exerts significant impact on physical aspects of quality of life (QoL) in PsA. CVD and mental disorders adversely influence functional capacity as well as mental and social dimensions of QoL, respectively. The impact of comorbidities should be taken into account by clinicians and researchers assessing PROs.

Available data shows associations between chronotype, circadian rhythms, sleep quality and fibromyalgia (FM) presentation. However, no studies have explored links between the chronobiological variables and effectiveness of pharmacotherapy. We aimed to assess the chronotypes, circadian rhythms, sleep-wake cycle and sleep quality in FM and their links to treatment response to serotonin and noradrenalin reuptake inhibitors (SNRI). 60 FM patients: 30 responsive to SNRI (FM T[+]), 30 non-responsive to SNRI (FM T[-]) and 30 healthy controls participated. Subjects were assessed by physician and with questionnaire tools: Composite Scale of Morningness, Biological Rhythms Interview of Assessment in Neuropsychiatry, Sleep-Wake Pattern Assessment Questionnaire, Pittsburgh Sleep Quality Index and Fibromyalgia Impact Questionnaire. ANOVA analysis and simple logistic regressions were used to examine the relationships between chronological variables and response to SNRI. FM T[-] vs. FM T[+] presented lower morning affect (11.50[95%CI 9.96-13.04] vs. 14.00[95%CI 12.42-15.57];p=0.04), anytime wakeability (2.27[95%CI 1.4-3.13] vs. 4.03[95%CI 2.99-5.08];p=0.013) worse overall (11.40[95%CI 9.92-12.88] vs. 7.97[95%CI 6.75-9.19];p=0.002) and subjective (1.70[95%CI 1.30-2.01] vs. 1.17[95%CI 0.94-1.39];p=0.008) sleep quality, higher circadian rhythm disruptions (55.47[95%CI 52.32-58.62] vs. 44.97[95%CI 41.31-48.62];p<0.001), sleep disturbances (1.63[95%CI 1.38-1.68] vs. 1.30[95%CI 1.1-1.5];p=0.04), sleeping-medication use (1.80[95%CI 1.27-2.32] vs. 0.70[95%CI 0.28-1.12];p=0.003). Levels of morningness (AIC=82.91,OR=0.93,p=0.05), morning affect (AIC=81.901,OR=0.86,p=0.03) diurnal dysrhythmia (AIC=69.566,OR=1.14,p<0.001), anytime wakeability (AIC=80.307,OR=0.76,p=0.015), overall sleep quality (AIC=74.665, OR=1.31,p=0.002) subjective sleep quality (AIC=79.353, OR=2.832,p=0.01) and disturbances (AIC=82.669,OR=2.54,p=0.043), sleep medication use (AIC=77.017, OR=1.9,p=0.003) and daytime disfunction (AIC=82.908, OR=1.971,p=0.049) were predictors of non-response to SNRI. Chronobiological variables vary between FM T[+] and FM T[-] and are predictors of non-response to SNRI.
RESUMO
OBJECTIVE: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a variable clinical manifestation, potentially leading to death. Importantly, patients with SLE have an increased risk of neoplastic disorders. Thus, this study aimed to comprehensively evaluate the clinical and laboratory characteristics of patients with SLE and with or without malignancy. METHODS: We conducted a retrospective analysis of medical records of 932 adult Caucasian patients with SLE treated at the University Hospital in Kraków, Poland, from 2012 to 2022. We collected demographic, clinical, and laboratory characteristics, but also treatment modalities with disease outcomes. RESULTS: Among 932 patients with SLE, malignancy was documented in 92 (9.87%), with 7 (7.61%) patients experiencing more than one such complication. Non-hematologic malignancies were more prevalent (n = 77, 83.7%) than hematologic malignancies (n = 15, 16.3%). Patients with SLE and malignancy had a higher mean age of SLE onset and a longer mean disease duration than patients without malignancy (p < 0.001 and p = 0.027, respectively). The former group also presented more frequently with weight loss (odds ratio [OR] = 2.62, 95% confidence interval [CI] 1.61-4.23, p < 0.001), fatigue/weakness (OR = 2.10, 95% CI 1.22-3.77, p = 0.005), and fever (OR = 1.68, 95% CI 1.06-2.69, p = 0.024). In the malignancy-associated group, we noticed a higher prevalence of some clinical manifestations, such as pulmonary hypertension (OR = 3.47, 95% CI 1.30-8.42, p = 0.007), lung involvement (OR = 2.64, 95% CI 1.35-4.92, p = 0.003) with pleural effusion (OR = 2.39, 95% CI 1.43-3.94, p < 0.001), and anemia (OR = 2.24, 95% CI 1.29-4.38, p = 0.006). Moreover, the patients with SLE and malignancy more frequently had internal comorbidities, including peripheral arterial obliterans disease (OR = 3.89, 95% CI 1.86-7.75, p < 0.001), myocardial infarction (OR = 3.08, 95% CI 1.41-6.30, p = 0.003), heart failure (OR = 2.94, 95% CI 1.30-6.17, p = 0.005), diabetes mellitus (OR = 2.15, 95% CI 1.14-3.91, p = 0.011), hypothyroidism (OR = 2.08, 95% CI 1.29-3.34, p = 0.002), arterial hypertension (OR = 1.97, 95% CI 1.23-3.23, p = 0.003), and hypercholesterolemia (OR = 1.87, 95% CI 1.18-3.00, p = 0.006). Patients with SLE and malignancy were treated more often with aggressive immunosuppressive therapies, including cyclophosphamide (OR = 2.07, 95% CI 1.30-3.28, p = 0.002), however median cumulative cyclophosphamide dose in malignancy-associated SLE subgroup was 0 g (0-2 g). Interestingly, over a median follow-up period of 14 years (ranges: 8-22 years) a total of 47 patients with SLE died, with 16 cases (5.28%) in the malignancy-associated SLE group and 31 cases (5.73%) in the non-malignancy SLE group (p = 0.76). The most common causes of death were infections (21.28%) and SLE exacerbation (8.51%). CONCLUSION: The study highlights the relatively frequent presence of malignancies in patients with SLE, a phenomenon that demands oncological vigilance, especially in patients with a severe clinical course and comorbidities, to improve long-term outcomes in these patients.
RESUMO
BACKGROUND: Lupus nephritis (LN) manifests systemic lupus erythematosus (SLE) and is characterized by various clinical and laboratory features. This study aimed to comprehensively evaluate the characteristics of LN patients according to the time of LN diagnosis: early-onset (LN diagnosed within one year from SLE diagnosis) vs. delayed-onset (LN diagnosed more than one year after SLE diagnosis). METHODS: We conducted a retrospective analysis of medical records from all SLE patients treated at the University Hospital in Kraków, Poland, from 2012 to 2022. We collected data on demographic, clinical, and laboratory characteristics, including histological findings, treatment modalities, and disease outcomes. Statistical analyses were performed to identify factors impacting LN development and prognosis. RESULTS: Among 331 LN patients, early-onset was diagnosed in 207 (62.54%) and delayed-onset was documented in 122 cases (36.86%). In 2 (0.6%) LN cases, the time of first kidney manifestation in the SLE course was unknown. Delayed-onset LN had a higher female-to-male ratio and younger age at SLE diagnosis. This group was associated with more severe clinical manifestations. In turn, studied subgroups did not differ in internist comorbidities, kidney histopathology, and family history regarding autoimmune diseases. Delayed-onset LN exhibited a higher frequency of anti-dsDNA, anti-Smith, anti-Ro, anti-RNP, and anti-cardiolipin IgG autoantibodies. During a 14-year follow-up period, 16 patients died. Mortality rate and causes of death were comparable in both analyzed subgroups. CONCLUSIONS: More severe clinical manifestations in delayed-onset LN prompt strict monitoring of non-LN SLE patients to diagnose and treat kidney involvement early. Also, recognizing the higher frequency of autoantibodies such as anti-dsDNA or anti-Smith in delayed-onset LN underscores the potential value of autoantibody profiling as a diagnostic and prognostic tool.

Recent reports have demonstrated that endothelial injury is critical in the pathogenesis of systemic sclerosis (SSc) and is associated with increased levels of circulating inflammatory biomarkers. This study aims to analyze the serum concentrations of selected cytokines and evaluate their relationship with SSc clinics and the long-term course of the disease. This study included 43 SSc patients and 24 matched healthy controls. In both groups, we measured serum levels of inflammatory cytokines related to the inflammatory response, such as tumor necrosis factor (TNF)α, interferon (IFN)γ, interleukin (IL)-4, IL-6, IL-10, and IL-17, and fibroblast activation protein (FAP). Additionally, in SSc patients, we evaluated the presence of four single nucleotide polymorphisms (SNPs) located in the promotor region of the TNFA gene, namely rs361525, rs1800629, rs1799964, and rs1799724, which might be related to increased TNFα concentrations. The main aim consisted of associating inflammatory cytokines with (1) clinical disease characteristics and (2) longitudinal observation of survival and cancer prevalence. SSc patients were characterized by a 17% increase in serum TNFα. There was no other difference in serum cytokines between the studied groups and diffuse vs. limited SSc patients. As expected, evaluated serum cytokines correlated with inflammatory biomarkers (e.g., IL-6 and C-reactive protein). Interestingly, patients with higher IL-17 had decreased left ventricle ejection fraction. During the median 5-year follow-up, we recorded four cases of neoplastic diseases (lung cancer in two cases, squamous cell carcinoma of unknown origin, and breast cancer with concomitant multiple myeloma) and nine deaths. The causes of death included lung cancer (n = 2), renal crisis (n = 1), multiple-organ failure (n = 1), and unknown reasons in five cases. Surprisingly, higher TNFα was associated with an increased cancer prevalence, while elevated IL-17 with death risk in the follow-up. Furthermore, the AG rs361525 genotype referred to higher TNFα levels than GG carriers. Both AG rs361525 and CT rs1799964 genotypes were associated with increased cancer risk. Higher serum concentrations of TNFα characterize the SSc patients, with the highest values associated with cancer. On the other hand, increased IL-17 in peripheral blood might predict poor SSc prognosis. Further research is needed to validate these findings.

Psoriatic arthritis (PsA) is a chronic inflammatory disease, characterised by the pathological occurrence of two opposite phenomena-osteoresorption and osteogenesis. Dickkopf-related protein 1 (DKK1) which inhibits the Wingless protein (Wnt) signalling pathway has been shown to be a master regulator of bone remodeling in inflammatory rheumatic diseases. However, the exact relationship between DKK1 serum level and bone remodelling is not clear. The goal of this study is to review state-of-the-art knowledge on the association of serum DKK1 with a bone remodelling in PsA. The MEDLINE-PubMed, EMBASE, Scopus, Web of Science and DOAJ databases were searched for appropriate papers. The English terms: 'DKK1', 'Dickkopf-1' 'Dickkopf related protein 1', 'psoriatic arthritis' and 'PsA' were used for search purposes. Eight original articles and two reviews were identified up to August 2023. In four out of 8 discussed studies DKK1 serum level was higher in PsA patients than in healthy controls [Dalbeth, p < 0.01; Diani, p < 0.001; Chung, p < 0.01; Abd el Hamid, p < 0.001)], it was comparable in another (Daousiss, p = 0.430) and was lower in two (Fassio2017, p < 0.05; Fassio2019, p < 0.05). In one study, the comparative groups included patients with axial spondyloarthritis, where DKK1 serum levels were lower in PsA groups [Jadon, peripheral PsA, p = 0.01]. The true relative serum concentration of DKK1 in PsA, as well as its influence on osteogenesis and osteoresorption, is still equivocal. Further studies on this matter with consistent and stringent methodology are warranted.
RESUMO
Pain catastrophizing is a maladaptive mechanism associated with the exaggerated experience of pain, increased rumination and feelings of helplessness. The main objective of this study was to explore whether increased pain catastrophizing is independently associated with a lower proportion of low disease activity (LDA) in rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondylarthritis (axSpA). Demographics, comorbidities, treatment, disease activity measures and patient-reported outcome data were recorded in RA, PsA and axSpA patients. Pain catastrophizing score (PCS) was assessed using a standardised questionnaire. For each diagnosis, composite disease activity scores with distinct cut-off values for LDA, i.e. DAS28-CRP (RA), DAPSA (PsA) and ASDAS-CRP (axSpA) were calculated and used as the dependent variable in logistic regression reflecting LDA achieved. A total of one thousand two hundred and twenty nine patients were included: 580 with RA, 394 with PsA and 255 with axSpA. In the multivariable analysis, pain catastrophizing was independently associated with LDA rates in axSpA (OR 0.33, 95% CI [0.12, 0.88]) amongst tested groups. In RA (OR 0.90, 95% CI [0.64, 1.28]) and PsA (OR 0.77, 95% CI [0.55, 1.07]), a statistically significant association was not observed. Higher PCS was independently associated with not achieving LDA in axSpA. Our data, however, indicate that pain catastrophizing, which also reflects a patient's personality traits and coping abilities, plays a less important role for the patient than general pain perception.

Randomized controlled trials showed high comparability of biosimilar rituximab (bs-RTX) GP2013 to biologic originator RTX (bo-RTX). Data on effectiveness of switching from bo-RTX to bs-RTX, starting therapy with bs-RTX, and bs-RTX drug survival in real-world setting are sparse. To explore long-term drug effectiveness and survival of bs-RTX GP2013 in rheumatoid arthritis (RA) patients both naïve to and mandatory switched from bo-RTX, and to clarify reasons for treatment cessation. Retrospective observational cohort study including RA outpatient clinic patients treated with bs-RTX between 2018 and 2021 in Norway. Patients were examined and monitored using recommended measures for disease activity and patient-reported outcomes (PROs). For description of population medians and interquartile range were used. Difference between observation times was assessed with Signed-Rank test, drug survival with Kaplan-Meier survival analysis. Reasons for discontinuation were ascertained. Among 110 patients, at baseline, 88 were mandatory switched from bo-RTX and 22 were RTX-naïve. During 2-year follow-up, disease activity and PROs measures remained stable in switchers subgroup and improved in subgroup starting bs-RTX for the first time. Overall drug survival was 80.0% after 1 year and 57.7% after 2 years and was significantly higher in bs-RTX-switched than in bs-RTX-naïve patients (p = 0.036). Two most frequently reported reasons for drug discontinuation were remission (38.6%) and doctor's decision (27.1%). RA patients treated with bs-RTX had satisfactory treatment response and drug retention rates which supports equivalence of bs-RTX GP2013 to bo-RTX, both in patients naïve to and mandatory switched from bo-RTX.

Rheumatoid arthritis (RA) and ankylosing spondylitis (AS) are severe chronic inflammatory joint diseases with different immune-mediated mechanisms playing a role in their pathogenesis. Rheumatoid arthritis is an erosive arthritis of peripheral joints and AS is a spondyloarthropathy affecting mainly sacroiliac and spinal joints leading to excessive bone formation and ankylosis. The coexistence of RA and AS in the same patient is rare. Presented here is a 52-year-old patient with long-standing AS with bilateral ankylosis of sacroiliac joints who developed peripheral symmetric polyarthritis while being treated with the interleukin 17 inhibitor secukinumab introduced due to secondary inefficacy of the tumor necrosis a inhibitor etanercept. He was finally diagnosed with seropositive RA coexisting with AS and treatment was changed to the Janus kinase inhibitor tofacitinib. Eventually, remission was sustained with use of the interleukin 6 inhibitor tocilizumab. This is the first case of RA developing during anti-interleukin 17 therapy. Although tocilizumab lacks efficaciousness in AS, in this case therapy was succesful as the RA-driving cytokine mechanism possibly prevailed.
RESUMO
Pain catastrophizing (PC), defined as tendency to describe pain in more exaggerated terms, to ruminate more or to feel helpless about it. Main objective was to illuminate PC in rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA), revealing its prevalence and associations from a biopsychosocial perspective, including its association with health-related quality of life (HRQoL). Measures reflecting the biological, social and psychological perspective were recorded in RA, PsA and axSpA outpatients. Biological variables including demographics, disease activity and patient reported outcomes (PROs) along with variables reflecting psychological and social domains were collected. RAND12 questionnaire was used to explore HRQoL and standardized questionnaire was used to reveal pain catastrophizing score (PCS). 1229 patients were recruited (RA 580, PsA 394, axSpA 255). Mean (SD) PCS were for RA 1.88 (1.39), PsA 2.06 (1.45) and axSpA 2.27 (1.37). Proportion of pain catastrophizers (score ≥ 4) was not statistically different between RA (10.5%), PsA (12.7%) and axSpA (15.3%). Across all diagnoses, variables reflecting biological subjective domain explained more PCS variability (adjusted R2 35.3-49.9%) than psychological (28.4-33.6%), social (22.4-28.4%) and biological objective (4.3-9.9%) domains. HRQoL was significantly lower in pain catastrophizers across all diagnoses. No substantial differences in proportion of pain catastrophizers between RA, PsA and axSpA patients were found. Higher PCS (score ≥ 4) was best explained by biological subjective measures and corresponded with inferior HRQoL in all diseases. Several biological objectives, psychological and social measures were also associated with higher PCS.

Hypereosinophilic syndrome (HES) is a group of a rare diseases characterized by marked eosinophilia in blood or tissue and eosinophil-related clinical manifestations. Benralizumab is a humanized, monoclonal antibody against interleukin 5 (IL-5) receptor α, which is expressed on human eosinophils. Here, we present the case of a patient with severe HES in whom treatment with benralizumab, an anti-IL-5 receptor monoclonal antibody, was initiated 6 months ago. Prior to benralizumab administration, the patient was treated with glucocorticoids (GS) and mepolizumab. However, instead of the applied treatment and normal level of peripheral eosinophils the patient presented with fluctuating lower respiratory tract symptoms and recurrent exacerbations of HES. Treatment with benralizumab (30 mg s.c. every 4-6 weeks) was started, resulting in significant improvement of respiratory signs and symptoms, normalization of eosinophil count and significant reduction of the methylprednisolone dose (after 5 doses of benralizumab administration). No substantial side effects have been noted during treatment and 6-month follow-up. We argue that in the severe and relapsing course of HES, rescue treatment with benralizumab should be taken into account, particularly in cases of relative inefficacy of GS and mepolizumab.
RESUMO
Ankylosing spondylitis (AS) is associated with accelerated atherosclerosis and enhanced cardiovascular morbidity and mortality compared to the general population. The mechanisms and mediators of this phenomenon have not been fully explained, but an expanding body of evidence demonstrates that increased cardiovascular risk in AS is heralded by endothelial dysfunction. We performed a literature review using the PubMed database from the year 2006 up to 2018. In this article we review the epidemiology, current evidence for impaired endothelial function, potential mechanisms and markers controlling this dysfunction, and finally we summarize the data regarding the efficacy of pharmacotherapy in reducing endothelial dysfunction in patients suffering from AS.
