Patient perspectives on the pathway to psoriatic arthritis diagnosis: results from a web-based survey of patients in the United States

Diagnostic delay in psoriatic arthritis: insights from a nationwide multicenter study

This study aimed to investigate the duration of diagnostic delay in patients with psoriatic arthritis (PsA) and identify potential contributing factors using a comprehensive, population-based approach. Data were obtained from the Turkish League Against Rheumatism (TLAR)-Network, involving patients who met the CASPAR criteria. Diagnostic delay was defined as time interval from symptom onset to PsA diagnosis, categorized as ≤ 2 years and > 2 years. Temporal trends were assessed by grouping patients based on the year of diagnosis. Various factors including demographics, clinical characteristics, disease activity, quality of life, physical function, disability, fatigue, and well-being were examined. Logistic regression models were used to identify factors associated with diagnostic delay. Among 1,134 PsA patients, mean diagnostic delay was 35.1 months (median: 12). Approximately 39.15% were diagnosed within 3 months, and 67.02% were diagnosed within 24 months. Patients experiencing longer delays had higher scores in Psoriatic Arthritis Quality of Life Questionnaire (PsAQoL), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), patient's global assessment (PtGA) and physician's global assessment (PhGA). Diagnostic delay has decreased over time, with median delay falling from 60 to 24 months throughout pre-2010 and 2015-2019 terms. Several factors were identified as significant contributors to delayed diagnosis, including lower levels of education (OR = 2.63), arthritis symptoms preceding skin manifestations (OR = 1.72), low back pain at first visit (OR = 1.60), symptom onset age (OR = 0.96), and psoriasis subtype (OR = 0.25). Timely diagnosis of PsA is crucial for effective management and improved outcomes. Despite recent improvements, about one-third of PsA patients still experience delays exceeding 2 years. By identifying influential factors such as education level, arthritis symptoms preceding skin manifestations, initial visit symptoms, age of symptom onset, and psoriasis subtype, healthcare practitioners may create specific techniques to help in early detection and intervention.

Window of opportunity in psoriatic arthritis: the earlier the better?

OBJECTIVES

To investigate whether there is a window of opportunity for psoriatic arthritis (PsA) patients and to assess which patient characteristics are associated with a longer diagnostic delay.

METHODS

All newly diagnosed, disease-modifying antirheumatic drug-naïve PsA patients who participated in the Dutch southwest Early PsA cohoRt and had ≥3 years of follow-up were studied. First, total delay was calculated as the time period between symptom onset and PsA diagnosis made by a rheumatologist and then split into patient and physician delays. The total delay was categorised into short (<12 weeks), intermediate (12 weeks to 1 year) or long (>1 year). These groups were compared on clinical (Minimal Disease Activity (MDA) and Disease Activity index for PSoriatic Arthritis (DAPSA) remission) and patient-reported outcomes during 3 years follow-up.

RESULTS

708 PsA patients were studied of whom 136 (19%), 237 (33%) and 335 (47%) had a short, intermediate and long total delay, respectively. Patient delay was 1.0 month and physician delay was 4.5 months. Patients with a short delay were more likely to achieve MDA (OR 2.55, p=0.003) and DAPSA remission (OR 2.35,p=0.004) compared with PsA patients with a long delay. Patient-reported outcomes showed numerical but non-significant differences between the short and long delay groups. Female patients and those presenting with enthesitis, chronic back pain or normal C-reactive protein (CRP) had a longer delay.

CONCLUSIONS

In PsA, referral and diagnosis within 1 year is associated with better clinical outcomes, suggesting the presence of a window of opportunity. The most gain in referral could be obtained in physician delay and in females, patients with enthesitis, chronic back pain or normal CRP.

Prevalence of Musculoskeletal Symptoms in Patients with Psoriasis and Predictors Associated with the Development of Psoriatic Arthritis: Retrospective Analysis of a US Claims Database

INTRODUCTION

Psoriasis (PsO) is associated with the development of psoriatic arthritis (PsA). Patients with PsO often experience pre-PsA musculoskeletal (MSK) symptoms, leading to potential structural damage and substantial disease burden with impact on function. The objective of this study is to describe prevalence rates and evidence of MSK symptoms, including incidence of comorbid PsA diagnosis, in patients newly diagnosed with PsO and identify factors associated with PsA diagnosis.

METHODS

This retrospective analysis included administrative claims from the Optum Research Database for adult patients with a new PsO diagnosis between January 2008 and February 2019. Eligible patients had ≥ 2 claims for PsO on unique dates, were aged ≥ 18 years at the date of the first claim with a diagnosis of PsO (index date), and had continuous enrollment with medical and pharmacy coverage for 12 months before (baseline period) and ≥ 12 months following the index date. Primary outcomes were incidence of comorbid PsA diagnosis, prevalence of MSK symptoms other than PsA, and evidence of MSK symptoms collected at baseline and assessed in 12-month intervals through 60 months.

RESULTS

Of the 116,203 patients with newly diagnosed PsO, 110,118 were without baseline comorbid PsA. High prevalence rates of MSK symptoms among patients with only PsO were seen at baseline (47.1%), 12 months (48.2%), and 60 months (82.1%). Patient age, baseline MSK symptoms, and baseline MSK symptom-related healthcare utilization were associated with increased hazard of a PsA diagnosis.

CONCLUSION

Increased prevalence rates of MSK symptoms and burden are experienced by patients newly diagnosed with PsO through 60 months of follow-up. Several baseline factors were associated with increased risk of PsA diagnosis.

Fluorescence-optical imaging as a promising easy-to-use imaging biomarker to increase early psoriatic arthritis detection in patients with psoriasis: a cross-sectional cohort study with follow-up

OBJECTIVES

To evaluate the ability of fluorescence-optical imaging (FOI) to detect preclinical musculoskeletal inflammatory signs in patients with skin psoriasis at risk of developing psoriatic arthritis (PsA).

METHODS

This investigator-initiated prospective exploratory study evaluated adult patients with psoriasis with musculoskeletal complaints and/or nail psoriasis within the last 6 months. Patients underwent a comprehensive rheumatological clinical examination (CE) along with musculoskeletal ultrasound (MSUS) and FOI of both hands at a single visit. Patients with CE-/MSUS-/FOI+ findings had MRI performed on the symptomatic or dominant hand within 7 days. If MRI was negative, the patients were followed over 2 years for the onset of clinically manifest PsA.

RESULTS

A total of 389 patients were referred from dermatology centres and evaluated at 14 rheumatology sites in Germany. Seventy-seven (20%) patients with CE-/US-/FOI- were considered to have psoriasis only. PsA was diagnosed in 140/389 patients (36%) based on CE alone and in another 55 patients (14%) by additional MSUS; overall, 50% of the patient cohort was diagnosed with PsA. One hundred sixteen patients (30%) were FOI+ (CE-) of which 40 (37%) were FOI+/MRI+. In the 2-year follow-up of the FOI+/CE- patients, clinical PsA was confirmed in another 12%.

CONCLUSION

FOI is a promising method for the detection of signs of musculoskeletal inflammation in hands that may serve as an early imaging biomarker for transitions from psoriasis to PsA. This imaging technique has the potential to detect PsA in at-risk patients with psoriasis, reduce time to PsA diagnosis and improve patient outcomes.

Body surface area affected by psoriasis and the risk for psoriatic arthritis: a prospective population-based cohort study

OBJECTIVE

Increasing psoriasis severity has been associated with comorbidities including cardiovascular disease. The objective of this study was to examine the association of psoriasis severity with the development of PsA.

METHODS

A prospective population-based cohort study was performed within The Health Improvement Network, a UK medical record database. Patients aged 25-60 years with a code for psoriasis were randomly selected between 2008 and 2011. Questionnaires were sent to their general practitioners to confirm the diagnosis of psoriasis and provide the patient's approximate body surface area (BSA). Incidence of PsA was calculated by BSA, and Cox proportional hazard ratios were used to examine the risk of developing PsA by BSA category after adjusting for other covariates.

RESULTS

Among 10 474 questionnaires sent, 9987 (95%) were returned, 9069 (91%) had confirmed psoriasis, and BSA was provided for 8881 patients: 52% had mild psoriasis, 36% moderate psoriasis and 12% severe psoriasis. The mean age was 46, and 49% were female. Mean follow-up time was 4.2 years (s.d. 2.1); the incidence of PsA was 5.4 cases per 1000 person-years. After adjusting for age and sex, BSA >10% [hazard ratio (HR) 2.01, 95% CI: 1.29, 3.13], BSA 3-10% (HR 1.44, 95% CI: 1.02, 2.03), obesity (HR 1.64, 95% CI: 1.19, 2.26) and depression (HR 1.68, 95% CI: 1.21, 2.33) were associated with incident PsA.

CONCLUSIONS

In this large prospective cohort study, BSA assessed by general practitioners was a strong predictor of developing PsA, and obesity and depression were additive risk factors.

Incidence and prevalence of psoriatic arthritis in patients with psoriasis stratified by psoriasis disease severity: Retrospective analysis of an electronic health records database in the United States

BACKGROUND

Among patients in the United States with psoriasis (PsO), limited data exist on the incidence and prevalence of psoriatic arthritis (PsA) based on disease severity.

OBJECTIVE

To assess the incidence, prevalence, and predictors of PsA among patients with PsO stratified by PsO severity using treatment type.

METHODS

Incidence of PsA per 100 PsO patient-years (PY) and prevalence were assessed using the Optum electronic health records database. Incidence was assessed from PsO diagnosis and 1 year after PsO diagnosis overall and stratified by mutually exclusive treatment classes as a severity surrogate.

RESULTS

The overall incidence of PsA was 2.9 (95% CI, 2.9-3.0) events per 100 PY. The incidence (95% CI) by severity surrogate was 2.1 (2.1-2.1), 9.9 (9.5-10.4), and 17.6 (16.9-18.3) events per 100 PY for patients with mild, moderate, and severe PsO as determined by receiving nonsystemics, nonbiologic systemic therapy, and biologics, respectively. When excluding patients diagnosed with PsA 1 year after PsO diagnosis, overall incidence was lower (1.7 [95% CI, 1.6-1.7] events per 100 PY), with similar trends for treatment-severity surrogates.

LIMITATIONS

Results may not be generalizable to a wider population.

CONCLUSION

The risk of developing PsA increased with disease severity and was highest in patients with the most severe PsO.

Current Medication Practices and Preferences Among Patients With Psoriatic Arthritis

OBJECTIVE

The aim of this study was to evaluate real-world psoriatic arthritis (PsA) medication use and patient medication preferences.

METHODS

This is a cross-sectional survey of Classification for Psoriatic Arthritis criteria defined PsA patients recruited from a single-center PsA registry from June to September 2020. Preferences were ranked on a 5-point Likert scale ranging from "not at all important" to "extremely important."

RESULTS

One hundred thirty-seven patients (29%) responded. The median duration (years) of PsA skin and joint symptoms was 19 (interquartile range, 10-34) and 12 (interquartile range, 8-21), respectively. The most common initial immunomodulatory medications were anti-tumor necrosis factor α (35%), methotrexate (19%), and anti-phosphodiesterase 4 (anti-PDE4) (12.4%). At survey administration, the most common immunomodulatory therapies were anti-tumor necrosis factor α (30%), anti-interleukin 17 (IL-17) (20.4%), and methotrexate (10.2%). After 2018, when updated guidelines from the American College of Rheumatology/National Psoriasis Foundation were published, a significantly higher percentage of patients' first medication was an anti-IL-17 compared with 2018 or earlier (30% vs 3.5%, p < 0.001), a pattern also seen with anti-PDE4 (40% vs 11.5%, p < 0.012). Medication preferences most ranked as "extremely" important were prevention of joint damage (80%), ability to perform daily activities (71%), prevention of pain (70.1%), rheumatologist recommendation (63%), and medication adverse effects (62%).

CONCLUSIONS

The significant increase of anti-IL-17 and anti-PDE4 medications as initial treatment after 2018 may reflect their inclusion as potential initial therapy in updated guidelines, along with the importance placed by patients on medication adverse effects. Given the expanding armamentarium of PsA medications, it is increasingly important to align patient preferences and therapeutic options to ensure durable use of effective therapy.

Longitudinal analysis of the patient pathways to diagnosis of psoriatic arthritis

Background

The occurrence of health events preceding a psoriatic arthritis (PsA) diagnosis may serve as predictors of diagnosis. We sought to assess patients’ real-world experiences in obtaining a PsA diagnosis.

Methods

This retrospective cohort study analyzed MarketScan claims data from January 2006 to April 2019. Included were adult patients with ≥ 2 PsA diagnoses (ICD-9-CM/ICD-10-CM) ≥ 30 days apart with ≥ 6 years of continuous enrolment before PsA diagnosis. Controls were matched 2:1 to patients with PsA. Health events (diagnoses and provider types) were analyzed before PsA diagnosis and additionally stratified by presence of psoriasis.

Results

Of 13,661 patients, those with PsA had an increased history of coding for arthritis and dermatologic issues (osteoarthritis [48% vs 22%], rheumatoid arthritis [18% vs 2%], and psoriasis [61% vs 2%]) vs those without PsA. Diagnoses of arthritis, axial symptoms, and tendonitis/enthesitis increased over time preceding PsA diagnosis; notably, a sharp rise in psoriasis diagnoses was observed 6 months before PsA diagnosis. Rheumatology consults were more common immediately preceding a PsA diagnosis. Dermatologists were unlikely to code for arthritis and musculoskeletal issues, while rheumatologists were unlikely to code for psoriasis; general practitioners focused on axial and musculoskeletal symptoms. PsA was most commonly diagnosed by rheumatologists (40%), general practitioners (22%), and dermatologists (7%).

Conclusions

Rheumatologists, general practitioners, and dermatologists diagnosed two thirds of patients with PsA. Musculoskeletal symptoms were common preceding a PsA diagnosis. Greater awareness of patterns of health events may alert healthcare providers to suspect a diagnosis of PsA.

Differentiating Psoriatic Arthritis from Osteoarthritis and Rheumatoid Arthritis: A Narrative Review and Guide for Advanced Practice Providers

Psoriatic arthritis (PsA) is a chronic inflammatory disease that affects multiple organ systems and is characterized by skin and joint manifestations. PsA is frequently undiagnosed and/or misdiagnosed, especially because of the similarities in clinical presentation shared with other arthritic diseases, including rheumatoid arthritis (RA) and osteoarthritis (OA). An accurate and timely diagnosis of PsA is crucial to prevent delays in optimal treatment, which can lead to irreversible joint damage and increased functional disability. Patients are usually seen by a number of different healthcare providers on their path to a diagnosis of PsA, including advanced practice providers (APPs). This review provides a comprehensive overview of the characteristic features that can be used to facilitate the differentiation of PsA from RA and OA. Detailed information on clinical manifestations, biomarkers, radiologic features, and therapeutic recommendations for PsA included here can be applied in routine clinical settings to provide APPs with the confidence and knowledge to recognize and refer patients more accurately to rheumatologists for management of patients with PsA.

A clinical perspective on risk factors and signs of subclinical and early psoriatic arthritis among patients with psoriasis

Psoriasis is a chronic, immune-mediated disease that includes a broad spectrum of systemic manifestations, complications, and comorbidities. Approximately 20%-30% of patients with psoriasis eventually develop psoriatic arthritis, and up to half of those without psoriatic arthritis experience subclinical musculoskeletal abnormalities. Recognition of early musculoskeletal inflammatory signs in patients with psoriasis is important to understand the extent and severity of this systemic disease, assess the risk of structural joint damage, and ensure timely and effective treatment of the complete spectrum of psoriatic disease. Delayed or ineffective treatment can lead to decreased quality of life, irreversible musculoskeletal damage, and loss of function. In this review, we highlight features of subclinical or early psoriatic arthritis among patients with psoriasis of which dermatologists should be aware. Recent knowledge of features of preclinical psoriatic arthritis in patients with psoriasis is presented. We briefly discuss important risk factors, clinical features, and other characteristics of patients likely to progress from psoriasis to psoriatic arthritis that should be known by dermatologists. Screening tools commonly used in the dermatology clinic to detect psoriatic arthritis are also critically reviewed. Finally, we provide expert commentary for dermatologists concerning the treatment of patients with psoriasis and subclinical signs of early psoriatic arthritis.

Risk of Osteoarthritis in an Incident Cohort of People With Psoriatic Arthritis: A Population-based Cohort Study

OBJECTIVE

To determine the risk of a diagnosis of osteoarthritis (OA) in patients with psoriatic arthritis (PsA) compared to patients with psoriasis and a general population cohort.

METHODS

Incident PsA patients aged 18-89 years at diagnosis were identified from the United Kingdom Clinical Practice Research Datalink between 1998 and 2014. All patients with PsA were matched to 2 cohorts of patients, both at a 1:4 ratio. The first cohort included patients with psoriasis (and no PsA) and the second was a general population cohort (with no psoriasis or PsA). The baseline prevalence of OA was calculated for each study cohort. The incidence of OA was calculated, and adjusted relative risks (RRadj) were calculated using conditional Poisson regression.

RESULTS

We identified 6783 incident PsA patients. The baseline prevalence of OA ranged from 22.1% (95% CI 21.1-23.1) in the PsA cohort to 12.6% (95% CI 12.2-13.0) and 11.0% (95% CI 10.6-11.3) in the psoriasis and general population cohorts, respectively. The incidence of OA was significantly higher in the PsA cohort compared to the psoriasis and general population cohorts after adjusting for BMI (RRadj 1.68, 95% CI 1.46-1.93, and RRadj 1.86, 95% CI 1.62-2.14, respectively).

CONCLUSION

An increased risk of OA was observed in patients with PsA compared to patients with psoriasis alone and those in the general population. Further work is needed to determine whether this reflects a true increase in OA risk or misdiagnosed PsA, and the extent to which it can be explained by differences in the opportunity for OA diagnosis between cohorts.

Irisin enhances osteogenic differentiation of mouse MC3T3-E1 cells via upregulating osteogenic genes

Osteoporosis affects millions of individuals and remains a clinical challenge in terms of prevention and treatment. The present study aimed to investigate the effect of irisin on osteogenic differentiation by exposing MC3T3-E1 cells to different concentrations of irisin. Treated cells were assayed for osteoblast proliferation and osteogenic differentiation by measuring alkaline phosphatase (ALP) activity, calcium deposition, formation of mineralized nodules and the expression of osteogenic genes using reverse transcription-quantitative PCR. The proliferation of MC3T3-E1 cells was unaffected by irisin at the concentrations tested of up to 100 ng/ml (P>0.05). ALP activity and mineralized nodule formation were significantly enhanced by irisin in a dose- and time-dependent manner, indicating that irisin promotes osteoblast differentiation of MC3T3-E1 cells. The expression of osteogenic genes, including ALP, collagen I, runt-related transcription factor 2, osterix, osteopontin, osteocalcin, osteoprotegerin and estrogen receptor α, increased significantly after irisin treatment. The present study demonstrated that irisin promoted the osteogenic differentiation of MC3T3-E1 cells, possibly by upregulating the expression of osteogenic genes and markers. Therefore, irisin may be worthy of further investigation as a potential therapeutic agent for osteoporosis.

Diagnostic Delay in Psoriatic Arthritis: A Population-based Study

OBJECTIVE

To examine demographic and clinical characteristics associated with diagnostic delay in psoriatic arthritis (PsA).

METHODS

We characterized a retrospective, population-based cohort of incident adult (≥ 18 yrs) patients with PsA from Olmsted County, Minnesota, from 2000-2017. All patients met the classification criteria. Diagnostic delay was defined as the time from any patient-reported PsA-related joint symptom to a physician diagnosis of PsA. Factors associated with delay in PsA diagnosis were identified through logistic regression models.

RESULTS

Of the 164 incident PsA cases from 2000 to 2017, 162 had a physician or rheumatologist diagnosis. Mean (SD) age was 41.5 (12.6) years and 46% were female. Median time from symptom onset to physician diagnosis was 2.5 years (IQR 0.5-7.3). By 6 months, 38 (23%) received a diagnosis of PsA, 56 (35%) by 1 year, and 73 (45%) by 2 years after symptom onset. No significant trend in diagnostic delay was observed over calendar time. Earlier age at onset of PsA symptoms, higher BMI, and enthesitis were associated with a diagnostic delay of > 2 years, whereas sebopsoriasis was associated with a lower likelihood of delay.

CONCLUSION

In our study, more than half of PsA patients had a diagnostic delay of > 2 years, and no significant improvement in time to diagnosis was noted between 2000 and 2017. Patients with younger age at PsA symptom onset, higher BMI, or enthesitis before diagnosis were more likely to have a diagnostic delay of > 2 years, whereas patients with sebopsoriasis were less likely to have a diagnostic delay.

Gaps in moderate plaque psoriasis management: A survey of Saudi dermatologists

Background:

There are many barriers that usually lead to under-treatment of moderate psoriasis patients, with subsequent unsatisfactory results and clinical outcomes.

Objective:

Given this lack of consistent guidelines on treating moderate plaque psoriasis patients, the aim of the current study is to define how Saudi dermatologists define and treat such cases in the real-world clinical setting.

Methods:

We conducted an online cross-sectional survey from May 2020 to October 2020, involving all eligible dermatologists working at different academic, governmental, and private sectors in Saudi Arabia.

Results:

Finally, a total of 260 dermatologists were included in the final analysis; out of them, 140 (53.8%) were males and 120 (46.2%) were females. Regarding the tools used by participating dermatologists for diagnosis of moderate psoriasis, most of the participants (86.5%) used Body Surface Area (BSA), 7.3% used Physician Global Assessment (PGA), and 6.2% used Dermatology Life Quality Index (DLQI). Cutoff scores for defining moderate psoriasis varied widely among surveyed dermatologists. The surveyed dermatologists reported that 46% of their patients with moderate plaque psoriasis were receiving biologics as their primary therapy, while 24.1% were receiving prescription topical treatment, 20.3% were receiving an oral systemic therapy, 4.9% were using over-the-counter topical treatment, and 4.7% were receiving phototherapy.

Conclusion:

There is a pervasive lack of consensus regarding the definition of moderate psoriasis, with reported wide ranges among the commonly used severity tools in psoriasis patients.

Trends in psoriatic arthritis epidemiology in Poland

Psoriatic arthritis (PsA) is a heterogeneous inflammatory arthritis, usually seronegative and associated with psoriasis (Ps). The prevalence and incidence of psoriatic arthritis show strong ethnic and geographic variations. The aim of the study was to assess the epidemiological trends in psoriatic arthritis in Poland. The National Health Fund (NHF) database for the period 2008-2018 was analyzed. PsA was defined as ICD-10 codes L40.5, M07, M07.0, M07.1, M07.2 and M07.3, while psoriasis as ICD-10 codes L40 and L40.X (L40.0 to L40.9). A steady increase in the number of PsA patients (from 16,790 to 32,644) and in PsA recorded prevalence (from 38.47 per 100,000 in 2008 to 73.11 per 100,000 in 2018) was observed between 2008 and 2018. The PsA/Ps ratio increased to a similar extent (from 8.3 to 17.5%). The percentage of PsA patients receiving rehabilitation services remained constant throughout the observation period (mean: 17.35%; range 16.7-18.9%). The study showed a steady and continuous increase in PsA recorded prevalence. A simultaneous increase in the PsA/Ps ratio suggests that the main reason for the observed trend is greater disease detection .

Defining Pre-Clinical Psoriatic Arthritis in an Integrated Dermato-Rheumatology Environment

In excess of three quarters of patients with psoriatic arthritis (PsA) have preceding psoriasis (PsO), which offers a clinical biomarker for the recognition of early PsA. Numerous surveys have shown a remarkably high frequency of clinically occult musculoskeletal symptoms in psoriasis patients. Imaging studies, particularly ultrasound, show a high prevalence of subclinical enthesitis and other inflammatory changes in psoriasis subjects. Since a serum biomarker, such as the case of anti-citrullinated protein antibodies (ACPA) in rheumatoid arthritis, neither exists nor seems biologically plausible at this point, this article explores how integration of rheumatological and dermatological assessment can be facilitated for the early recognition of potential PsA. Given that scalp disease is a PsA predictor, but may be managed in the community, then a particular need to access this group is needed. An integrated approach between rheumatology and dermatology can involve joint clinics, parallel clinics with discussion of relevant cases or virtual contact between specialties. Early therapy evaluation and integrated strategies have considerable implications for minimizing suffering and joint damage in PsA.

Patient-Centered Care in Psoriatic Arthritis-A Perspective on Inflammation, Disease Activity, and Psychosocial Factors

Psoriatic arthritis (PsA) is a seronegative spondyloarthropathy characterized by skin lesions, dactylitis, and enthesitis. Patients with PsA suffer from a variety of psychosocial difficulties and nonspecific symptoms early on in the disease course and continue to experience progressive disease due to delays in diagnosis and treatment. Symptoms initially viewed as somatization could lead to undertreatment and promote psychological distress, poor coping, and negative patient-provider relationships. Pain and fatigue are important complaints that affect the patient's perception and may need to be addressed with a multidisciplinary approach. Maladaptive cognitive responses can lead to a negative illness perception and impact patient beliefs and concerns over treatment, as well as nonadherence. An underlying inflammatory component in affective disorders has been examined, though whether and how it may interact mechanistically in PsA warrants interest. Cognitive behavioral therapy represents a nonpharmacological treatment modality that can be combined with cytokine-targeted therapy to address both somatic and psychological complaints. Future directions for research include: (1) Elucidating nonspecific manifestations (e.g., subclinical stage, differential with functional syndromes) of PsA and how they impact diagnosis and management; (2) characterizing immune-mediated components of mood disorders in PsA; and (3) whether a bidirectional approach with abrogating inflammation and psychotherapeutic support leads to improved outcomes.

The effect of Qigong Wuqinxi for osteopenia and primary osteoporosis: A protocol for systematic review and meta analysis

INTRODUCTION

Osteoporosis (OP) and related fragility fractures are a significant public health problem which leads to pain, disability, loss function of independence, considerable complications and increased mortality. Exercise training is the only alternative strategy to improve multiple skeletal and fall risk factors simultaneously. Wuqinxi is 1 of the Chinese mind-body exercises using to improve physical and mental health and fight against diseases for thousands of years. Our study aims to systematically review the existing literature to further explore the efficacy and safety of Wuqinxi in the prevention and treatment of osteopenia and OP.

METHODS AND ANALYSIS

The following electronic databases (PubMed, Science Citation Index, Embase (Ovid) database, the Cochrane Library, the China National Knowledge Infrastructure, the China Biology Medicine disc, the China Science and Technology Journal Database, the Wan fang Database, ClinicalTrials.gov and the Chinese Clinical Trial Registry Platform) will be searched from the beginning to 1 June 2020. Only randomized controlled trials will be enrolled, in which the intervention group must include a form of Wuqinxi, while the control group can involve other conventional treatment or no intervention. The potential outcome measures will include bone mineral density values, bone turnover markers, fragility fractures, quality of life, pain scores, and adverse events. The Cochrane risk of bias assessment tool will be used to assess the risk of bias in each study.

RESULTS

The current study is a protocol for systematic review and meta-analysis without results, and data analysis will be carried out after the protocol. We will share our findings in the third quarter of 2021.

CONCLUSION

This review aims to evaluate up-to-date evidence of Wuqinxi for bone health in English or Chinese language studies, and explore whether Wuqinxi can be used as an adjuvant treatment for osteoporosis and osteopenia.

ETHICS AND DISSEMINATION

Ethical approval is not required as the review is a secondary study based on published literature. The results of the study will be published in peer-reviewed publications and disseminated electronically or in print.
