Skeletal Radiol 2024; 53:455-463. [PMID: 37594519 DOI: 10.1007/s00256-023-04425-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 08/04/2023] [Accepted: 08/04/2023] [Indexed: 08/19/2023]
Abstract
OBJECTIVE To establish the scanning protocol for 2-dimensional shear wave elastography (SWE) on normal entheses by investigating the possible confounding factors that may increase the variability of measured elasticity. MATERIAL AND METHODS 30 normal quadriceps entheses were scanned using SWE to compare the stiffness and coefficient variation by changing the ultrasonic coupling gel thickness, knee position, region of interest size, and scanning plane. RESULTS No significant difference in median shear wave velocity (SWV) was observed in different coupling gel thicknesses. The median SWV was higher in the knee flexion position than in the extended position (p < 0.001). Increased knee flexion led to stiffer quadriceps enthesis and higher SWV (ρ = 0.8, p < 0.001). The median SWV was higher when the diameter region of interest was 4.0 mm than 2.0 mm (p = 0.001). The median SWV was higher in the transverse plane than in the longitudinal plane (p < 0.001). Strong correlation was found between SWV and the degree of the shear wave to muscle fiber direction (ρ = 0.8, p < 0.001). The coefficient variation was lower in a gel thickness of 2.5 cm, with an extended knee, a region of interest of 2.0 mm, and a longitudinal plane (p > 0.05). For interobserver reliability for the proposed protocol, the intraclass correlation coefficients was 0.763. CONCLUSION In this study, we determined supine position with the knee extended; using 2.0 mm diameter region of interest and image acquisition at the longitudinal plane with thicker layer coupling gel seems most appropriate to reliably image healthy quadriceps entheses with SWE.

Evaluation of the agreement between the ACR 1990 fibromyalgia tender points and an enthesitis score in patients with axial spondyloarthritis. Rheumatology (Oxford) 2023; 62:2757-2764. [PMID: 36573318 DOI: 10.1093/rheumatology/keac683] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2022] [Accepted: 11/24/2022] [Indexed: 08/03/2023] Open
Abstract
OBJECTIVES Coexistence of FM represents a challenge in the evaluation of enthesitis in patients with axial spondyloarthritis (axSpA) due to a possible overlap between the tender points (TP) due to enthesitis and those of FM. The objective was to assess the agreement between the MASES enthesitis score and the tender points of the ACR 1990 criteria in patients with axSpA. METHODS This was a cross-sectional ancillary analysis of the Predict-SpA study (NCT03039088). Patients had a diagnosis of axSpA according to their rheumatologist and an indication to start a TNFα blocker. All patients were screened for FM according to the FiRST questionnaire. A physician was asked to assess 31 anatomically described sites in a random order without knowing to which instrument the site belonged (i.e. the 18 ACR 1990 TP and the 13 MASES sites). Agreement between the MASES and the ACR 1990 TPs by the intraclass correlation coefficient (ICC), also stratified by the presence/absence of concomitant FM according to the FiRST. RESULTS Among the 526 patients, 53% were men and 202 (38%) had FM. Radiographic sacroiliitis and MRI sacroiliitis were present in 56% and 68% patients, respectively. Patients were mostly men (53.4%) with radiographic and MRI sacroiliitis in 56% and 68% patients, respectively. Mean number of ACR 1990 TP was 5.4 (s.d. 4.6) and mean MASES was 4.2 (s.d. 3.6). ICC between both scores was 0.7 [95% CI (0.6, 0.8)]. ICC between both scores was 0.6 [95% CI (0.3, 0.8)] and 0.7 [95% CI (0.6, 0.7)] for patients with and without FM, respectively. CONCLUSION These results suggest a significant overlap between both scores in patients with axSpA, including in those without concomitant FM.

Abstract
Diagnostic imaging in rheumatology has evolved over the centuries, and novel imaging modalities, including musculoskeletal ultrasonography (MSUS) and magnetic resonance imaging (MRI), are being widely used in the 21st century. With the increase in availability of molecular target-specific therapies, including biologic agents and Janus kinase (JAK) inhibitors, the therapeutic outcome of inflammatory arthritis has changed, and early and accurate diagnosis of inflammatory rheumatic diseases has become more important. Given this situation, MSUS, which is a portable, convenient, noninvasive, and cost-effective imaging technique, plays an important role in the diagnosis of rheumatic diseases. MSUS can be used to detect subclinical inflammation and to accurately determine the distribution of joint involvement and inflammation sites in each joint. Definitive diagnosis for patients with early arthritis should be made after noting their history and performing clinical examination, laboratory testing, and additional procedures. However, MSUS is an extension of physical examination and it can provide a further opportunity and motivation to consider differential diagnoses rather than a conclusive diagnosis. This review aims to describe the usefulness of MSUS in differential diagnoses of the phenotype of early inflammatory arthritis.

Magnetic resonance imaging characteristics in patients with spondyloarthritis and clinical diagnosis of heel enthesitis: post hoc analysis from the phase 3 ACHILLES trial. Arthritis Res Ther 2022; 24:111. [PMID: 35578245 PMCID: PMC9109380 DOI: 10.1186/s13075-022-02797-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Accepted: 05/03/2022] [Indexed: 11/10/2022] Open
Abstract
Objective To investigate the imaging characteristics and clinically assess heel enthesitis in spondyloarthritis (SpA) by applying in a post hoc analysis the Heel Enthesitis Magnetic Resonance Imaging Scoring system (HEMRIS) in blinded and centrally-read MRI data from the ACHILLES trial (NCT02771210). Methods ACHILLES included patients (≥18 years) with active psoriatic arthritis or axial SpA with clinical and MRI-positive heel enthesitis refractory to standard treatment. Patients were randomized to receive subcutaneous secukinumab 150/300 mg or placebo. At week 24, patients on placebo were switched to secukinumab treatment. MRI-positive heel enthesitis was confirmed in all patients by local investigators. MRIs were performed at 3 timepoints: screening and weeks 24 and 52. In the present analysis, all MRIs were re-evaluated by 2 blinded central readers in a consensus read fashion for a priori defined MRI parameters based on HEMRIS. Results At screening, 171/204 (83.8%) of patients presented with entheseal inflammation and/or structural damage, considering both the Achilles tendon and plantar fascia. Pathologies were more evident in the Achilles tendon area compared to the plantar aponeurosis. The most frequent pathologies were intra-tendon hypersignal and retrocalcaneal bursitis. The mean total entheseal inflammation score at screening in the Achilles tendon area was 2.99 (N=204) and the mean change (standard deviation [SD]) from screening to weeks 24 and 52 was − 0.91 (1.99) and − 0.83 (2.12) in the secukinumab group vs − 0.48 (1.86) and − 0.80 (1.98) in the placebo-secukinumab group, respectively. The mean total structural damage score at screening was 1.36 (N=204) and the mean change (SD) from screening to weeks 24 and 52 was 0.00 (0.65) and − 0.06 (0.56) in the secukinumab group vs 0.08 (0.48) and 0.04 (0.75) in the placebo-secukinumab group, respectively. Conclusions Based on the newly developed HEMRIS, entheseal inflammation and/or structural damage was confirmed in 83.3% of ACHILLES patients. Pathologies were more evident in the Achilles tendon area compared to plantar fascia, with the inflammatory parameters being more responsive with secukinumab treatment compared to placebo. The present analysis, with detailed information on individual MRI parameters, contributes to the scientific debate on heel enthesitis. Trial registration ClinicalTrials.gov NCT02771210.

Activity, Functional Status and Enthesitis Index in Patients with Axial
Spondyloarthritis. AKTUEL RHEUMATOL 2022. [DOI: 10.1055/a-1749-4695] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/18/2022]
Abstract
Abstract
Background Sonoelastography (SE) is a new ultrasound (US)-based technique
able to assess tissue elasticity. Using conventional US, it is sometimes
difficult or even impossible to distinguish pathologic tissue because it often
presents with the same echogenicity as the surrounding healthy tissue. This
study aimed to evaluate SE findings in Achilles tendons of patients with axial
spondyloarthritis (axSpA) and to assess how these findings are associated with
disease-related parameters.
Material and Methods Sixty-four consecutive patients (37 men, 27 women;
mean age 39.7 years; range 20–65 years) with axSpA and 30 sex and
age-matched healthy controls were enrolled in the study. Disease activity was
evaluated using the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI),
whereas functional capacity was evaluated using the Bath Ankylosing Spondylitis
Functional Index (BASFI). Erythrocyte sedimentation rate (ESR), C-reactive
protein (CRP) and the Spondyloarthritis Research Consortium of Canada (SPARCC)
enthesitis index were recorded. All participants underwent an SE examination of
the Achilles tendon and measurement of the strain index (SI).
Results The mean right and left SI were significantly higher in axSpA
patients than in controls (2.96±0.94 vs. 1.90±0.45;
p<0.001; 2.95±0.95 vs. 1.92±0.48, p<0.001,
respectively). In axSpA patients, both right and left SI were significantly
correlated with the BASDAI, BASFI and SPARCC enthesitis indices, but not with
ESR or CRP.
Conclusion AxSpA patients had an increased SI compared with healthy
subjects and these values were associated with disease activity, functional
capacity and the enthesitis index. SE may be a useful tool for the evaluation of
Achilles tendons in patients with axSpA.

Abstract
Spondyloarthritis (SpA) is a chronic inflammatory condition that can have a predominately peripheral or axial presentation. Axial SpA (axSpA) affects the axial skeleton with either radiographic (r-axSpA) or nonradiographic (nr-axSpA) changes. Radiographic changes are a late disease feature and earlier disease stages can be identified by incorporating other imaging methods. The diagnosis of axSpA is a clinical diagnosis and classification criteria are not aimed to be diagnostic tools. The split between r-axSpA and nr-axSpA is artificial and we should move toward the unifying concept of axSpA. Our understanding of genetics, biomarkers, and immunopathophenotypes will drive further refinement of classification criteria.

Abstract
Nail psoriasis is a refractory disease that affects 50-79% skin psoriasis patients and up to 80% of patients with psoriatic arthritis (PsA). The pathogenesis of nail psoriasis is still not fully illuminated, although some peculiar inflammatory cytokines and chemokines seems to be the same as described in psoriatic skin lesions. Psoriatic nail involving matrix can cause pitting, leukonychia, red spots in lunula, and nail plate crumbling, while nail bed involvement can result in onycholysis, oil-drop discoloration, nail bed hyperkeratosis, and splinter hemorrhages. The common assessment methods of evaluating nail psoriasis includes Nail Psoriasis Severity Index (NAPSI), Nail Assessment in Psoriasis and Psoriatic Arthritis (NAPPA), Nail Psoriasis Quality of life 10 (NPQ10), and so on. Treatment of nail psoriasis should be individualized according to the number of involving nail, the affected site of nail and presence of skin and/or joint involvement. Generally, topical therapies are used for mild nail psoriasis, while biologic agents such as etanercept are considered for severe nail disease and refractory nail psoriasis. Even though the current literature has shown some support for the pathogenesis, clinical presentation, or therapies of nail psoriasis, systemic review of this multifaceted disease is still rare to date. We elaborate recent developments in nail psoriasis epidemiology, pathogenesis, anatomy, clinical manifestation, diagnosis, differential diagnosis, and therapies to raise better awareness of the complexity of nail psoriasis and the need for early diagnosis or intervention.

Abstract
PURPOSE OF REVIEW Despite immunology and translational therapeutics advances in inflammatory arthritis over the past two decades, the enthesis, which is the epicentric of the spondyloarthritis family pathological process, retains many mysteries because of tissue inaccessibility that hampers direct immune study. As entheses are subject to almost continuous mechanical stress and spondyloarthritis is linked to microdamage or injury and joint stress, it is cardinal to understand the physiological changes occurring within the entheses not only to be able to differentiate disease from health but also to understand the transition normal physiology break down and its merges into spondyloarthritis-related disease. RECENT FINDINGS Imaging has played a major role in understanding the enthesis in human. Remarkable insights from enthesis functioning and microdamage in normal and with ageing including those linked to body mass index is emerging. The impact of mechanical stress and degenerative conditions on the development of the secondary entheseal vascular changes is not understood. Of note, ultrasound studies in psoriasis have shown higher power Doppler changes compared to controls pointing towards a role for vascular changes in the development of enthesitis in psoriatic arthritis. SUMMARY The literature pertaining to normal entheses changes with age, microdamage and vascular changes in health is providing a roadmap for understanding of the enthesis and its potential role in evolution of spondyloarthritis including psoriatic arthritis.

Abstract
Psoriatic arthritis (PsA) is an inflammatory potentially destructive disease that requires early diagnosis and therapeutic approach. Its main pathogenic event and the condition's hallmark is considered to be enthesitis. Clinical examination of the enthesis can be a challenge in the clinical practice; thus, ultrasonography (US) has emerged as an indispensable imaging tool for evaluating both structural and inflammatory changes of this structure. In the present study, we aimed to analyze the type and frequency of entheseal involvement in PsA patients by US examination, performing a retrospective study on 41 patients diagnosed with PsA. Ultrasonographically confirmed enthesitis, identified according to Outcome Measures in Rheumatology group (OMERACT, initially Outcome Measures in Rheumatoid Arthritis Clinical Trials) definitions, was present in 26 of the included patients, Achilles enthesis being the most common site involved. The prevalence of tendon structure abnormalities and the presence of entesophytes underlines the importance of chronic inflammation on entheseal sites. US examination has proven to be a reliable imaging method, with significant and continuous improvement, which is clearly a requisite part for current understanding and diagnosis of enthesitis and more than this, for the patient follow-up algorithm.

Abstract
OBJECTIVE To review the evidence surrounding the pathophysiology of enthesitis in axial spondyloarthritis (axSpA), its prevalence and contribution to the overall disease burden, and response to treatment at axial and peripheral sites. METHODS Literature searches of the Cochrane Library, PubMed, and Embase / Medline using the terms "enthesitis", "enthesopathy", "spondyloarthritis", "axial spondyloarthritis", and "ankylosing spondylitis" were conducted. Publications mentioning enthesitis or enthesopathy in the context of pathophysiology, diagnosis, or treatment were included. RESULTS Enthesitis is a common symptom of axSpA, occurring with high prevalence at axial and several peripheral sites. Inflammation at the site of enthesis is an early key manifestation of axSpA. Clinically evaluable enthesitis contributes significantly to the burden of disease, correlating with worse symptomatology and downstream structural damage. Despite its importance in driving axSpA disease processes, enthesitis is somewhat neglected in current approaches to disease assessment and management. Enthesitis is excluded from some commonly used disease activity measures, is not routinely assessed in clinical practice, and many methods of clinical assessment omit key accessible axial sites, such as the spinous processes. CONCLUSION Enthesitis plays a central role in driving the pathophysiology of axSpA. There is a need for a renewed focus on the early detection, measurement and treatment of enthesitis.

Consensus terminology for preclinical phases of psoriatic arthritis for use in research studies: results from a Delphi consensus study. Nat Rev Rheumatol 2021; 17:238-243.

Abstract
The concept of psoriatic arthritis (PsA) prevention is gaining increased interest owing to the physical limitation, poor quality of life and low remission rates that are achieved with current therapies for PsA. The psoriasis-to-PsA transition offers a unique opportunity to identify individuals at increased risk of developing PsA and to implement preventive strategies. However, identifying individuals at increased risk of developing PsA is challenging as there is no consensus on how this population should be defined. This Consensus Statement puts forward recommended terminology from the Psoriasis and Psoriatic Arthritis Clinics Multicenter Advancement Network (PPACMAN) for defining specific subgroups of individuals during the preclinical and early clinical phases of PsA to be used in research studies. Following a three-round Delphi process, consensus was reached for three terms and definitions: 'increased risk for PsA', 'psoriasis with asymptomatic synovio-entheseal imaging abnormalities' and 'psoriasis with musculoskeletal symptoms not explained by other diagnosis'. These terms and their definitions will enable improved identification and standardization of study populations in clinical research. In the future, as increasing evidence emerges regarding the molecular and clinical features of the psoriasis-to-PsA continuum, these terms and definitions will be further refined and updated.

Abstract
Juvenile idiopathic arthritis (JIA) is a heterogeneous group of chronic inflammatory arthritides that if inadequately treated, may be associated with chronic disability and deformity. Early diagnosis and treatment initiation is essential in the management of patients with JIA. Conventional means of evaluation of disease presence, disease activity and response to therapy including physical exam, labs and x-rays are at times limited and may be insufficient in making an accurate assessment. Musculoskeletal ultrasound (MSUS) is a well-established modality that is patient and family-friendly, non-invasive, does not require sedation and can be performed at the bedside in real-time. MSUS offers information that cannot be attained by standard outcome measures, and may help to advance both diagnosis and treatment of patients with JIA ultimately improving patient outcomes. This review explores the background of MSUS and the current evidence to support its potential role as a diagnostic, disease activity monitoring and interventional tool.

Abstract
Early differentiation between different types of inflammatory arthritis and subsequent initiation of modern treatments can improve patient outcomes by reducing disease activity and preventing joint damage. Routine clinical evaluation, laboratory testing, and radiographs are typically sufficient for differentiating between inflammatory and predominantly degenerative arthritis (e.g., osteoarthritis). However, in some patients with inflammatory arthritis, these techniques fail to accurately identify the type of early-stage disease. Further evaluation by ultrasound imaging can delineate the inflammatory arthritis phenotype present. Ultrasound is a noninvasive, cost-effective method that enables the evaluation of several joints at the same time, including functional assessments. Further, ultrasound can visualize pathophysiological changes such as synovitis, tenosynovitis, enthesitis, bone erosions, and crystal deposits at a subclinical level, which makes it an effective technique to identify and differentiate most common types of inflammatory arthritis. Limitations associated with ultrasound imaging should be considered for its use in the differentiation and diagnosis of inflammatory arthritides.

Abstract
OBJECTIVE This study aimed to determine the prevalence of subclinical enthesopathy in patients with psoriasis using power Doppler ultrasonography (PDUS) and its association with other disease parameters. MATERIAL AND METHODS A total of 50 patients with psoriasis (31 females) aged 19-70 years underwent a thorough clinical examination that included assessment of body mass index (BMI) and psoriasis area and severity index (PASI) score. Measurements of inflammatory markers, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), serum uric acid, and plain radiography of the heels, knees, and sacroiliac joints were performed for all patients. Patients without clinical evidence of arthritis or enthesitis underwent an ultrasonographic (US) examination. According to the US examination, patients were classified into group I (patients with enthesitis) and group II (patients without enthesitis). RESULTS In group I, Achilles enthesis was the most common site of US enthesitis (33.3%), followed by distal patellar enthesis (22.2%), proximal patellar enthesis (16.7%), quadriceps enthesis (16.7%), and plantar aponeurosis enthesis (11.1%). There was a statistically significant positive correlation between the occurrence of enthesitis and the patient's age, disease duration, PASI score, BMI, and hyperuricemia (p<0.05 for each). In contrast, there was no significant correlation between enthesitis and sex or radiographic sacroiliitis (p>0.05 for each). CONCLUSION In addition to the importance of PDUS as a complimentary tool for examining enthesis in patients with psoriasis, the presence of high PASI score, increased BMI and hyperuricemia, and a long disease duration can be considered as predictive parameters for the presence of psoriatic enthesitis.

Abstract
Background The impact of physical exercise on joints and tendons is still a matter of debate. The aim of this study was to investigate with ultrasound the acute effects of extreme physical exercise on knee and ankle joints and their surrounding structures in trained athletes. Methods Participants of the Munich marathon were examined by arthrosonography before and after long distance running. Ultrasound assessment included grey scale and power Doppler examination of the knee and talocrural joints with surrounding tendons. Findings consistent with joint effusion, tendon and/or entheseal pathologies were documented. In addition to the ultrasound evaluation, information on training habits and past or present arthralgia or joint swelling was gathered. Results One Hundred Five runners completed both the pre- and post-excercise ultrasound assessments (baseline and follow-up), resulting in the sonographic evaluation of 420 knee and talocrural joints. At baseline, 105 knee (50) and 38 talocrural joints (18.1) showed effusions, compared to 100 knee (47.6) and 33 talocrural joints (15.7 %) at follow-up. The differences were not significant (p > 0.05 each). Effusion size did not correlate with the timepoint of ultrasound assessment and was independent of covariates such as gender, age or running distance. Hypervascularity of the patellar tendon was detected in 21 cases (10.0 %) at follow-up in contrast to one at baseline (p < 0.001). This observation was more frequent in male than in female participants (p < 0.05). Conclusions Acute physical stress is significantly associated with hypervascularity of the patellar tendon. No significant changes of synovial effusion were detected in knee and talocrural joints.

Abstract
The objective of this study is to review the data on entheseal involvement in systemic disorders. A Pubmed search utilizing the indexing terms "enthesis" and "enthesitis" was conducted and the data pertinent to the aim of the review was extracted and organized in accordance with the preplanned structure of the manuscript. A number of cadaver-based studies, as well as studies using ultrasonography and magnetic resonance imaging, have detailed new distinct aspects of enthesis physiology and pathology in a variety of rheumatic and non-rheumatic systemic disorders. Major progress has been done in characterization of separate components of the enthesis organ, imaging of entheses, elaboration of the role and features of entheseal disease in spondyloarthropathies, juvenile idiopathic arthritis, osteoarthritis, familial Mediterranean fever, hyperuricemia, and other systemic conditions. The knowledge acquired and summarized herein shows that entheses can be affected in various ways in variety of medical disorders with different pathogenesis. Better understanding of the risk factors, mechanisms and natural history of enthesopathies is warranted. The current progress in the understanding of entheseal involvement in systemic disorders represents just the first step in resolving the entheses-related enigmas.

Abstract
BACKGROUND Enthesitis is considered a characteristic presentation of the second most common group of rheumatoid disorders, i.e. spondyloarthropathies (SpAs), particularly peripheral spondyloarthropathies. At the initial stages, enthesitis may be the only symptom of SpA, particularly in patients lacking the HLA-B27 receptor. MATERIAL/METHODS In light of diagnostic difficulties with detecting enthesitis in clinical examinations and laboratory investigations, many studies point out the high specificity of imaging studies, and particularly ultrasonography. RESULTS A total of 20% Achilles tendon entheses, 45% plantar aponeurosis entheses and 89.5% of flexor digiti brevis tendon entheses were unremarkable. In the remaining cases, the presentation of pathological lesions was not specific to enthesitis and might more likely correspond to degeneration or microinjuries of the entheses, beside the most obvious cases of achillobursitis or Kager's fat pad inflammation. CONCLUSIONS The studies demonstrated that ultrasound scans rarely confirm the clinical diagnosis of enthesitis.

Abstract
Spondyloarthritis (SpA) encompasses a group of disorders linked by overlapping clinical manifestations and genetic predisposition. Newer classification systems developed for adults with SpA focus on identifying individuals with axial or predominantly peripheral involvement. All forms of SpA can begin during childhood, and can be considered on a continuum with adult disease. Nevertheless, there are important differences in presentation and outcome that depend on age at onset. This article highlights these differences, what has been learned about genetics and pathogenesis of SpA, and important unmet needs for future studies.

Abstract
Interfaces between different tissues play an essential role in the biomechanics of native tissues and their recapitulation is now recognized as critical to function. As a consequence, imaging the hard/soft tissue interface has become increasingly important in the area of tissue engineering. Particularly as several biotechnology based products have made it onto the market or are close to human trials and an understanding of their function and development is essential. A range of imaging modalities have been developed that allow a wealth of information on the morphological and physical properties of samples to be obtained non-destructively in vivo or via destructive means. This review summarizes the use of a selection of imaging modalities on interfaces to date considering the strengths and weaknesses of each. We will also consider techniques which have not yet been utilized to their full potential or are likely to play a role in future work in the area.

Abstract
Psoriasis arthritis (PsA) encompasses many diverse clinical symptoms. Epidemiological data about the prevalence in general, predisposed age groups, prevalence of joint, spine, enthesis, and extra-articular manifestations are very heterogeneous. Even for the PsA specialist the clinical picture is not always easy to differentiate from other overlapping or clinically similar disease entities. This paper tries to give some guidance on how to screen for and how to detect PsA early in the population of psoriasis patients on the basis of the Mainz PsA screening and early diagnosis algorithm.
