Psychologic factors in scleroderma

Protocol for the development of a tool to map systemic sclerosis pain sources, patterns, and management experiences: a Scleroderma Patient-centered Intervention Network patient-researcher partnership

INTRODUCTION

Systemic sclerosis (SSc) is a rare, complex autoimmune rheumatic disease with multiple factors that contribute to pain. People with SSc emphasize the effect pain has on their quality of life, but no studies have systematically examined the frequency and relative importance of different SSc pain sources, patterns of pain from different sources, and pain management experiences. Our objectives are to (1) develop a tool, jointly with researchers, health care providers, and patients, to map sources of pain in SSc, determine patterns of pain from different sources, and understand pain management experiences; and (2) administer the final tool version to participants in the large multinational Scleroderma Patient-centered Intervention Network (SPIN) Cohort.

METHODS

First, we will use validated pain assessment tools as templates to develop an initial version of our pain assessment tool, and we will obtain input from patient advisors to adapt it for SSc. The tool will include questions on pain sources, pain patterns, pain intensity, pain management techniques, and barriers to pain management in SSc. Second, we will conduct nominal group technique sessions with people living with SSc and health care providers who care for people with SSc to further refine the tool. Third, we will conduct individual usability testing sessions with SPIN Cohort participants. Once the tool has been finalized, we will administer it to individuals in the multinational SPIN Cohort, which currently includes over 1,300 active participants from 54 sites in 7 countries. We will perform unsupervised clustering using the KAy-Means for MIxed LArge data (KAMILA) method to identify participant subgroups with similar profiles of pain sources (present or absent) and to evaluate predictors of subgroup membership. We will use latent profile analysis to identify subgroups of participants with similar profiles based on pain intensity scores for each pain source and evaluate predictors.

DISCUSSION

Once completed, our pain assessment tool will allow our team and other researchers to map sources of pain in SSc and to understand pain management experiences of people living with SSc. This knowledge will provide avenues for studies on the pathophysiology of pain in SSc and studies of interventions to improve pain management.

An online, two-day educational seminar had no impact on disease-specific knowledge in patients with systemic sclerosis

Systemic sclerosis (SSc) is a multifaceted disease, and its diagnosis triggers substantial anxiety and uncertainty for those affected. Currently, there are no valid data describing the impact of disease-specific patient education on the disease knowledge available. We created a two-day, online educational seminar to provide SSc patients with disease-specific information. The primary objective of the study was to observe the change in the disease-specific knowledge of the patients. A total of 118 patients were randomized into an intervention group and a waiting list control group. The change in knowledge was assessed using a multiple-choice test. The intervention group completed the questionnaire before, directly after, and 3 months after the seminar, while the waiting list control group also took the test 3 months before the seminar to rule out nonspecific learning. The primary outcome measure was the score difference between baseline and 3 months after baseline. The study was registered in the German Clinical Trials Register (protocol code DRKS00024915). The educational seminar resulted in a small, but measurable, increase in knowledge. While the two tests in the waiting list control group prior to the seminar did not show a nonspecific increase in disease knowledge, the intervention led to a numerical increase in knowledge (mean ± sd score difference 0.34 ± 1.31, 95% CI (- 0.23; 0.86), p = 0.26) that did not reach statistical significance. Multiple linear regression analysis showed that being a member of a self-help group (β = 1.12; p = 0.03) is a positive predictor of a higher disease knowledge. Although highly appreciated by participants, a two-day online seminar may not be the most appropriate format to generate measurable disease-specific knowledge. Self-help group membership was a positive predictor of a higher level of disease-specific knowledge prior to the educational seminar and should be recommended to every affected person.

Pain and Self-Efficacy Among Patients With Systemic Sclerosis: A Scleroderma Patient-Centered Intervention Network Cohort Study

BACKGROUND

Pain is one of the most common symptoms affecting patients with systemic sclerosis; however, little is known about the relationship between self-efficacy and pain and changes in pain over time.

OBJECTIVES

The purpose of this study was to describe the relationships between self-efficacy and pain in patients with systemic sclerosis, as well as determine whether changes in self-efficacy mediate changes in pain.

METHODS

A prospective longitudinal study was conducted using data from the Scleroderma Patient-Centered Intervention Network Cohort. The baseline sample included 1,903 adults, with a trajectory subsample of 427 who completed 3-month assessments across 3 years. Hierarchical (sequential) forward multivariable regression, covarying for participant characteristics, was conducted to determine the association between self-efficacy and patient characteristics on pain outcomes. Trajectory models, covarying for participant characteristics, were used to examine changes in self-efficacy and pain outcomes across time and whether self-efficacy mediated the pain trajectories.

RESULTS

Mean time since diagnosis was 9.5 years, with 39.2% diagnosed with diffuse cutaneous systemic sclerosis. Greater self-efficacy was associated with less pain interference and intensity. Increasing age, female gender, finger ulcers, and small joint contractures were related to greater pain interference and intensity. Esophageal gastrointestinal symptoms were associated with more pain interference. Self-efficacy and pain trajectories remained stable across time, and self-efficacy did not mediate the pain trajectories.

DISCUSSION

This study identified self-efficacy, age, gender, finger ulcers, small joint contractures, and esophageal gastrointestinal symptoms as important correlates associated with pain in patients with systemic sclerosis. In addition, this study found that self-efficacy and pain outcomes remained stable over time, providing important insights into the longitudinal pain experiences of patients with systemic sclerosis.

Effects of non-pharmacological and non-surgical interventions on health outcomes in systemic sclerosis: protocol for a living systematic review

INTRODUCTION

Systemic sclerosis (SSc; scleroderma) is a rare, chronic, autoimmune disease with a high level of burden, a significant impact on the ability to carry out daily activities, and a considerable negative impact on health-related quality of life. Non-pharmacological interventions could be provided to potentially improve mental and physical health outcomes. However, the effectiveness of non-pharmacological interventions on health and well-being among individuals with SSc has not been well established. The proposed living systematic review aims to identify and evaluate randomised controlled trial (RCT) evidence on the effectiveness of non-pharmacological and non-surgical interventions on mental and physical health outcomes and on the delivery of such services in SSc.

METHODS AND ANALYSIS

Eligible studies will be RCTs that examine non-pharmacological and non-surgical interventions aimed at improving health outcomes among individuals with SSc or the delivery of services intended to improve healthcare or support of people with SSc (eg, support groups). All RCTs included in a previous systematic review that sought studies published between 1990 and March 2014 will be evaluated for inclusion. Additional trials will be sought from January 2014 onwards using a similar, augmented search strategy developed by a health sciences librarian. We will search the MEDLINE, Embase, CINAHL, PsycINFO, Cochrane Library and Web of Science databases and will not restrict by language. Two independent reviewers will determine the eligibility of identified RCTs and will extract data using a prespecified standardised form in DistillerSR. Meta-analyses will be considered if ≥2 eligible RCTs report similar non-pharmacological interventions and comparable health outcomes. We will conduct a qualitative synthesis for interventions that cannot be synthesised via meta-analysis.

ETHICS AND DISSEMINATION

We will post initial and ongoing results via a website, publish results periodically via peer-reviewed journal publication, and present results at patient-oriented events.

Protocol for a partially nested randomized controlled trial to evaluate the effectiveness of the Scleroderma Patient-centered Intervention Network Support Group Leader EDucation (SPIN-SSLED) Program

BACKGROUND

Some people with rare diseases rely on peer-led support groups for disease-specific education and emotional and practical support. Systemic sclerosis (SSc), or scleroderma, is a rare autoimmune connective tissue disease. Many people with SSc cannot access support groups, and, when support groups exist, they may not be sustained due to challenges that could be addressed via leader training. The Scleroderma Patient-centered Intervention Network (SPIN), along with SSc patient organization partners, developed a training program for SSc patient support group leaders, the Scleroderma Support group Leader EDucation (SPIN-SSLED) Program. We recently completed a feasibility trial in which we successfully delivered the program to two groups of support group leaders who reported a high level of satisfaction with the program and its delivery. The primary objective of the full-scale SPIN-SSLED trial is to evaluate the effect of the program on support group leaders' self-efficacy for carrying out their leadership role. Secondary objectives include evaluating effects on leader burnout, leader satisfaction (participation efficacy), and emotional distress.

METHODS/DESIGN

The SPIN-SSLED trial is a pragmatic randomized controlled trial (RCT) in which 180 support group leaders will be randomly allocated to training groups of 6 participants each or to a waitlist control. We will use a partially nested RCT design to reflect dependence between individuals in training groups, but not in the waitlist control. Participants allocated to the training program will receive the 13-module SPIN-SSLED Program, delivered via webinar over the course of 3 months in weekly 60-90-min sessions. The primary outcome is leader self-efficacy, measured by the Scleroderma Support Group Leader Self-efficacy Scale post-intervention. Secondary outcomes are leader self-efficacy at 3 months post-intervention, and leader burnout, volunteer job satisfaction (participation efficacy), and emotional distress post-intervention and at 3 months post-intervention.

DISCUSSION

The SPIN-SSLED trial will test whether a training program for SSc patient support group leaders increases the self-efficacy of group leaders to carry out leadership tasks. The program has the potential to significantly improve the effectiveness and sustainability of existing SSc support groups, to increase the number of available support groups, and to be adapted for other chronic diseases.

Malnutrition, associated clinical factors, and depression in systemic sclerosis: a cross-sectional study

INTRODUCTION

The aim of this study was to evaluate the associations between malnutrition and the clinical features of the disease and depression in patients with systemic sclerosis (SSc).

METHOD

Patients with SSc who were followed up in our clinic were enrolled in the study. Malnutrition risk was assessed using the Malnutrition Universal Screening Tool (MUST). Skin involvement was assessed using the modified Rodnan skin score (mRSS) and interincisal distance (ID) measurements were used to assess the maximal mouth opening capacity. The Beck Depression Inventory (BDI) was used for measuring the severity of depression.

RESULTS

Ninety-eight patients with SSc (84.7% women; mean age 52.67 ± 11.26 years) were included in the study. According to the MUST scores, 61.2%, 15.3%, and 23.5% of patients had low, medium, and high risk for malnutrition, respectively. The mRSS was significantly higher in the group with high malnutrition risk compared with low-risk group (p = 0.014). Malnutrition risk was associated with interstitial lung disease and bowel involvement (p = 0.044 and p = 0.021, respectively). Interincisal distance was lower in the group with high malnutrition risk compared with the low-risk group (p = 0.003). Malnutrition risk was higher in patients who had mild-to-severe depressive symptoms than in those without (p = 0.012). Interincisal distance and bowel involvement were the most relevant factors for malnutrition.

CONCLUSIONS

The risk of malnutrition is increased in patients with SSc. In our study, microstomia and bowel involvement were the most relevantly associated factors with malnutrition.

KEY POINTS

• The risk of malnutrition is increased in patients with systemic sclerosis (SSc). • Microstomia and bowel involvement are found to be the most important factors associated with malnutrition. • Depressive symptoms are seen frequently among patients with SSc, and depression seems to be one of the etiologic factors or the result of malnourishment in SSc. • Assessment of nutritional status and the presence of depression should be a part of routine clinical visits of patients with SSc.

Support Groups in Scleroderma

PURPOSE OF REVIEW

This review presents evidence on support group effectiveness in common diseases, research on support groups in systemic sclerosis (SSc), and work underway by the Scleroderma Patient-centered Intervention Network in collaboration with patient organizations to train SSc support group leaders in order to improve support group access and the experiences of support groups for members and leaders.

RECENT FINDINGS

Giving and receiving emotional and practical support from others with SSc is an important reason that individuals with SSc attend support groups, but many patients cannot access support groups. SSc support group leaders report confidence in their ability to facilitate groups, but are less confident in tasks such as managing group dynamics and sustaining the group. The Scleroderma Support group Leader EDucation (SPIN-SSLED) Program was developed to provide training to support group leaders and was recently tested through a feasibility trial. A full-scale trial will commence in 2019.

The burden of depression in systemic sclerosis patients: a nationwide population-based study

BACKGROUND

Systemic sclerosis (SSc) can clinically present with psychological symptoms, including pain, depression, and distress about disfigurement, physical and social functioning. The existing small studies have reported a prevalence of depression ranging from 36% to 65% among SSc patients, likely reflecting the disease impact on the patient's self-image and function.

AIM OF THE STUDY

To investigate the association between SSc and depression using big data analysis methods.

METHODS

We designed a nation-wide epidemiological survey relying on a large database of 2500 SSc patients and explored the relationship between SSc and depression, but also the impact of depression on the survival of SSc patients. Chi-squared and t-tests were used for univariate analysis and a logistic regression model was used for multivariate analysis.

RESULTS

The proportion rate of depression among SSc patients was significantly higher than controls (16.2% vs 10.9%), and this proportion was even higher in female SSc patients and of low socioeconomic status. At the multivariate logistic regression, SSc was found to be an independent risk factor for depression with an OR of 1.55 (95%CI 1.29-1.88, p < 0.0001). No significant association was found between SSc-specific autoantibodies (anti-centromere, anti-Scl-70, anti-RNA polymerase III and anti-RNP) status and the risk of depression. Depression was not found to have a significant impact on the survival of SSc patients with an HR of 1.06 (0.80-1.42).

CONCLUSIONS

This study provides further support for the high prevalence of depression in SSc patients and therefore, SSc patients may benefit from a screening approach and a broad supportive care program.

Functioning in the emotional sphere and ways of coping with chronic connective tissue disease

Chronic illness is a strong stressor, and its occurrence in human life forces the individual to make adaptive changes. The aim of the study was to evaluate the reactions, behaviors, and emotional states of a person in the face of systemic connective tissue disease and ways of coping with this difficult situation. The method of choice was an individual case study. The subject was a 41-year-old patient, diagnosed with diffuse systemic sclerosis (dSSc) 8 years previously. The patient was characterized by lowered self-esteem, the presence of depressive symptoms, low level of hope for success, a reduced sense of competence, a tendency to use stress coping strategies focused on emotions and dominance of anxiety and tension. Emotional stress coping strategies, low level of hope for success, and non-acceptance attitude predispose the person suffering from systemic sclerosis (SSc) to exhibit depressive symptoms.

Performance of the Patient-Reported Outcomes Measurement Information System-29 in scleroderma: a Scleroderma Patient-centered Intervention Network Cohort Study

Objective

The Patient-Reported Outcomes Measurement Information System (PROMIS)-29 assesses seven health-related quality of life domains plus pain intensity. The objective was to examine PROMIS-29v2 validity and explore clinical associations in patients with SSc.

Methods

English-speaking SSc patients in the Scleroderma Patient-centered Intervention Network Cohort from 26 sites in Canada, the USA and the UK completed the PROMIS-29v2 between July 2014 and November 2015. Enrolling physicians provided medical data. To examine convergent validity, hypotheses on the direction and magnitude of correlations with legacy measures were tested. For clinical associations, t -tests were conducted for dichotomous variables and PROMIS-29v2 domain scores. Effect sizes (ESs) were labelled as small (<0.25), small to moderate (0.25-0.45), moderate (0.46-0.55), moderate to large (0.56-0.75) and large (>0.75).

Results

There were 696 patients (87% female), mean ( s . d .) disease duration 11.6 (8.7) years, 57% with limited cutaneous subtype. Validity indices were consistent with seven of nine hypotheses (| r | =0.51-0.87, P < 0.001), with minor divergence for two hypotheses. Gastrointestinal involvement was associated with significantly worse outcomes for all eight PROMIS-29v2 domains (moderate or moderate to large ES in six of eight). Presence of joint contractures was associated with significant decrements in seven domains (small or small to moderate ESs). Skin thickening, diffuse cutaneous subtype and presence of overlap syndromes were significantly associated (small or small to moderate ESs) with five or six domains.

Conclusion

This study further establishes the validity of the PROMIS-29v2 in SSc and underlines the importance of gastrointestinal symptoms and joint contractures in reduced health-related quality of life.

Biopsychosocial typologies of pain in a cohort of patients with systemic sclerosis

OBJECTIVE

Despite being a common problem in systemic sclerosis (SSc; scleroderma), the extant literature on pain has primarily focused on biomedical correlates, or bivariate relationships with a few psychological characteristics. There is a need to investigate the more heuristic biopsychosocial model, which incorporates the simultaneous contributions of medical, psychological, and social variables in understanding pain.

METHODS

Patients with SSc (n = 333) received clinical examinations and completed self-report surveys at enrollment in the Genetics versus Environment in Scleroderma Outcome Study. Latent profile analysis was used to derive biopsychosocial profiles of patients using skin thickening, percent predicted forced vital lung capacity, perceived physical health, health worry, mental health, and social support. The profiles were examined in relation to pain and pain medication usage.

RESULTS

A 3-profile solution provided the best fit to the data. Based on the biopsychosocial indicators, the profiles were characterized as managing (n = 217), resilient (n = 86), and distressed (n = 30). Between-group differences for pain emerged, with the distressed group, whose disease was less severe than the resilient group, reporting the highest pain and the greatest utilization of pain medication.

CONCLUSION

Clinicians should consider biopsychosocial characteristics as contributing factors to the experience of pain in patients with SSc. Patients who are similar to those in the distressed profile may be at an increased risk for pain and would likely benefit from a referral to a behavioral health or other ancillary service provider for pain management, rather than relying solely on pharmacologic therapies.

The short-term effect of gloving in combination with Traditional Thai Massage, heat, and stretching exercise to improve hand mobility in scleroderma patients

BACKGROUND

Systemic sclerosis (SSc) is a chronic, multisystem connective tissue disorder characterized by autoimmune activation, microvascular endothelium damage, and excessive collagen proliferation. The most affected hand presents claw hand deformity and microvascular disease. Deformed hands can cause functional disability and decrease the quality of life. A daily home program can improve mobility of scleroderma patients.

OBJECTIVE

We sought to determine the effect of a daily home exercise program on hand mobility among scleroderma patients.

MATERIALS AND METHODS

This was a randomized control trial. Twenty-eight participants were divided into two groups, both of which received the same daily home treatment: Group 1 with gloves (n = 14) and Group 2 without gloves (n = 14). The 2-week daily home program combined traditional Thai massage (TTM) with stretching exercises and heat. Hand mobility was assessed using hand mobility in scleroderma (HAMIS). The study was conducted in patients who were already on vasodilator drugs.

RESULTS

Both groups showed a significant improvement in hand mobility after 2 weeks of daily home exercise program (P < 0.05). Wearing the glove, however, resulted in better thumb mobility.

CONCLUSIONS

A daily home exercise program improved hand mobility among patients with scleroderma and wearing gloves may improve thumb mobility.

Clinical, functional and health-related quality of life correlates of clinically significant symptoms of anxiety and depression in patients with systemic sclerosis: a cross-sectional survey

Objectives

To identify clinical, functional and health-related quality of life (HRQoL) correlates of clinically significant symptoms of anxiety and depression in patients with systemic sclerosis (SSc).

Methods

Three-hundred-and-eighty-one patients fulfilling the American College of Rheumatology and/or the Leroy and Medsger criteria for SSc were assessed for visceral involvement, disability and HRQoL (assessed by SF-36). Clinically significant symptoms of anxiety and depression were evaluated with the Hospital Anxiety Depression Scale (HAD) (defined cut-off≥8).

Results

9.2% the patients had limited SSc, 50.5% limited cutaneous SSc (lcSSc), and 40.3% diffuse cutaneous SSc (dcSSc). Overall, 40.4% and 58.8% of the patients had clinically significant symptoms of depression and anxiety, respectively. Compared to patients without clinically significant symptoms of depression, patients with clinically significant symptoms of depression had poorer health status, HRQoL mental and physical component, and greater global disability, hand disability and aesthetic impairment. Compared to patients without clinically significant symptoms of anxiety, patients with clinically significant symptoms of anxiety had poorer SF-36 mental and physical component scores. On multivariable analysis, excluding mental component score of SF-36, variables independently associated with clinically significant symptoms of depression and anxiety were global disability and physical component of SF-36, plus female gender for clinically significant symptoms of anxiety only. Remarkably, patients with and without clinically significant psychiatric symptoms were comparable for all disease-related clinical features assessed.

Conclusion

High levels of clinically significant symptoms of anxiety and depression are observed among SSc patients. Clinically significant psychiatric symptoms are rather associated with increased disability and altered HRQoL, than with disease-specific organ manifestations.

Sexual Function in Italian Women with Systemic Sclerosis Is Affected by Disease-related and Psychological Concerns

Objective.

In patients with systemic sclerosis (SSc), sexual function is somewhat impaired. Our aim was to evaluate sexual function in women with SSc in comparison to controls, and to investigate the association with sociodemographic and disease characteristics, and physical and psychological variables.

Methods.

Forty-six women with SSc and 46 healthy women were assessed for sociodemographic characteristics and gynecological development and administered the Female Sexual Function Index (FSFI), Medical Outcomes Study Short Form-36 (SF-36), Health Assessment Questionnaire (HAQ), Hospital Anxiety and Depression Scale (HADS), Rosenberg Self-Esteem Scale, Coping Orientation to Problems Experienced-New Italian Version, and Functional Assessment of Chronic Illness Therapy-Fatigue Scale. Patients were also assessed for disease duration and subset, Female Sexual Function in SSc, Hand Mobility in Scleroderma test (HAMIS), Cochin Hand Functional Disability Scale, Mouth Handicap in Systemic Sclerosis Scale (MHISS), Disability Sexual and Body Esteem Scale (PDSBE); and fist closure, hand opening, and mouth opening.

Results.

In patients with SSc, only FSFI desire subscale score was significantly lower (p = 0.035) versus controls. Total FSFI score, similar to controls, was related with Medical Outcomes Study Short Form-36 mental component, HAQ (p = 0.022), MHISS (p = 0.038), and HAMIS (p = 0.037). In SSc, the main factors independently associated with sexual functioning were vaginal dryness [regression coefficient (B) = −0.72; p < 0.001], PDSBE (B = 0.42; p = 0.001), and HADS depression scale (B = −0.23; p = 0.035). Together, these variables explained 70% of the variance in the FSFI total score.

Conclusion.

In SSc, sexual function, although not different from controls, is influenced by specific disease-related and psychological concerns. Thus it should be included in patient evaluations and assessed in daily clinical practice.

The Scleroderma Patient-centered Intervention Network (SPIN) Cohort: protocol for a cohort multiple randomised controlled trial (cmRCT) design to support trials of psychosocial and rehabilitation interventions in a rare disease context

INTRODUCTION

Psychosocial and rehabilitation interventions are increasingly used to attenuate disability and improve health-related quality of life (HRQL) in chronic diseases, but are typically not available for patients with rare diseases. Conducting rigorous, adequately powered trials of these interventions for patients with rare diseases is difficult. The Scleroderma Patient-centered Intervention Network (SPIN) is an international collaboration of patient organisations, clinicians and researchers. The aim of SPIN is to develop a research infrastructure to test accessible, low-cost self-guided online interventions to reduce disability and improve HRQL for people living with the rare disease systemic sclerosis (SSc or scleroderma). Once tested, effective interventions will be made accessible through patient organisations partnering with SPIN.

METHODS AND ANALYSIS

SPIN will employ the cohort multiple randomised controlled trial (cmRCT) design, in which patients consent to participate in a cohort for ongoing data collection. The aim is to recruit 1500-2000 patients from centres across the world within a period of 5 years (2013-2018). Eligible participants are persons ≥18 years of age with a diagnosis of SSc. In addition to baseline medical data, participants will complete patient-reported outcome measures every 3 months. Upon enrolment in the cohort, patients will consent to be contacted in the future to participate in intervention research and to allow their data to be used for comparison purposes for interventions tested with other cohort participants. Once interventions are developed, patients from the cohort will be randomly selected and offered interventions as part of pragmatic RCTs. Outcomes from patients offered interventions will be compared with outcomes from trial-eligible patients who are not offered the interventions.

ETHICS AND DISSEMINATION

The use of the cmRCT design, the development of self-guided online interventions and partnerships with patient organisations will allow SPIN to develop, rigourously test and effectively disseminate psychosocial and rehabilitation interventions for people with SSc.

In systemic sclerosis, anxiety and depression assessed by hospital anxiety depression scale are independently associated with disability and psychological factors

Background. Anxious and depressive symptoms are frequent in Systemic Sclerosis (SSc). Our objective is to assess their prevalence and association with district and global disability and psychological variables. Methods. 119 SSc patients were assessed by Hospital Anxiety Depression Scale (HADS). Clinical depression and anxiety were defined for HADS score cutoff ≥8. Patients were assessed for psychological symptoms (RSES, COPE-NIV), hand (HAMIS, CHFDS, fist closure, and hand opening) and face disability (MHISS, mouth opening), global disability, and fatigue (HAQ, FACIT). Results. Both depression and anxiety in SSc are 36%. Depressive patients with comorbid anxiety have higher HADS-D score than patients with depression only (P = 0.001). HADS-A and -D are positively correlated with global disability, hands and mouth disability, fatigue, self-esteem and avoidance coping strategy, and, only HADS-A, also with social support (P < 0.05). By multiple regression, HADS-D is independently associated with FACIT-F (P < 0.001), RSES (P < 0.001), and MHISS total score (P = 0.016), together explaining 50% of variance. HADS-A is independently associated with RSES (P = 0.006), COPE-NIV SA (P = 0.003), COPE-NIV SS (P = 0.008), FACIT-F (P = 0.022), and MHISS mouth opening (P = 0.029), explaining 41% of variance. Conclusions. In SSc depression and anxiety correlate to local and global disabilities and psychological characteristics. Depressive patients with comorbid anxiety have higher level of depressive symptoms.

Use of the Patient-generated Index in systemic sclerosis to assess patient-centered outcomes

OBJECTIVE

To evaluate the content and construct validity of an individualized patient-reported instrument, the Patient-generated Index (PGI), in patients with systemic sclerosis (SSc), and to compare its performance to that of other instruments and to the Patient-reported Outcomes Measurement Information System (PROMIS) framework.

METHODS

Patients identified the 5 most important life areas affected by SSc, which we categorized into domains of the PROMIS framework (mental, physical, and social). Correlations were obtained between PGI and the Health Assessment Questionnaire (HAQ), the Medical Outcomes Study Short Form-36 (SF-36), and the Symptom Burden Index (SBI) scores.

RESULTS

Sixty-two patients with SSc completed the PGI: 87% women, 69% white, mean age 53 years, mean disease duration 8 years, and 63% with diffuse disease. A total of 258 individual life area responses were recorded: 54% in social health (social function and relationship subcomponents); 28% in physical health (physical function, symptoms, general physical health); and 19% in mental health (consisting largely of the affect subcomponent). Patient PGI responses were categorized into 6 of the 7 subcomponents of the PROMIS framework; substance use/alcohol was not identified. Statistically significant correlations ranging in absolute value from 0.26 to 0.50 were observed between the PGI and the HAQ, SF-36 summary component scores, and the large majority of SF-36 subscales and SBI components.

CONCLUSION

The PGI is a personalized instrument that adequately assessed a wide range of health-related quality of life outcomes within the PROMIS framework. The PGI captured additional constructs not yet defined within the framework that are important for patients with SSc.

My approach to the treatment of scleroderma

Systemic sclerosis (scleroderma) is unique among the rheumatic diseases because it presents the challenge of managing a chronic multisystem autoimmune disease with a widespread obliterative vasculopathy of small arteries that is associated with varying degrees of tissue fibrosis. The hallmark of scleroderma is clinical heterogeneity with subsets that vary in the degree of disease expression, organ involvement, and ultimate prognosis. Thus, the term scleroderma is used to describe patients who have common manifestations that link them together, whereas a highly variable clinical course exists that spans from mild and subtle findings to aggressive, life-threatening multisystem disease. The physician needs to carefully characterize each patient to understand the specific manifestations and level of disease activity to decide appropriate treatment. This is particularly important in treating a patient with scleroderma because there is no treatment that has been proven to modify the overall disease course, although therapy that targets specific organ involvement early before irreversible damage occurs improves both quality of life and survival. This review describes our approach as defined by evidence, expert opinion, and our experience treating patients. Scleroderma is a multisystem disease with variable expression; thus, any treatment plan must be holistic, yet at the same time focus on the dominant organ disease. The goal of therapy is to improve quality of life by minimizing specific organ involvement and subsequent life-threatening disease. At the same time the many factors that alter daily function need to be addressed, including nutrition, pain, deconditioning, musculoskeletal disuse, comorbid conditions, and the emotional aspects of the disease, such as fear, depression, and the social withdrawal caused by disfigurement.

Sociodemographic and disease correlates of body image distress among patients with systemic sclerosis

Background

Body image concerns are infrequently studied in systemic sclerosis (SSc), even though significant visible disfigurement is common. The objective of this study was to identify sociodemographic and disease-related correlates of dissatisfaction with appearance and social discomfort among people with SSc.

Methods

SSc patients came from the 15-center Canadian Scleroderma Research Group Registry. Sociodemographic information was based on patient self-report. Disease characteristics were obtained via physician examinations. The Brief-SWAP was used to assess dissatisfaction with appearance and social discomfort. Structural equation models were conducted with MPlus to determine the relationship of dissatisfaction with appearance and social discomfort with age, sex, education, marital status, race/ethnicity, disease duration, skin involvement, telangiectasias, skin pigmentation changes, and hand contractures.

Results

A total of 489 SSc patients (432 female, 57 male) were included. Extent of skin involvement was significantly associated with both dissatisfaction with appearance and social discomfort (standardized regression coefficients = 0.02, p = 0.001; 0.02, p = 0.020, respectively), as was skin involvement in the face (0.18, p = 0.016; 0.23, p = 0.006, respectively). Greater social discomfort was robustly associated with younger age (−0.017, p<0.001) and upper-body telangiectasias (0.32, p = 0.021). Dissatisfaction with appearance was associated with hand contractures (0.07, p = 0.036).

Conclusion

This study found that dissatisfaction with appearance and social discomfort were associated with numerous disfiguring characteristics of SSc, in addition to age. These results underline that there are multiple factors contributing to body image distress in SSc, as well as the need to attend to both disease and social contexts in understanding the impact of disfigurement among patients.

Feasibility and construct validity of PROMIS and "legacy" instruments in an academic scleroderma clinic

OBJECTIVE

The National Institutes of Health Patient-Reported Outcomes Measurement Information System (PROMIS) roadmap initiative is a cooperative group program of research designed to develop, evaluate, and standardize item banks to measure patient-reported outcomes relevant across medical conditions. The objective of the current study was to assess feasibility and evaluation of the construct validity of PROMIS item banks versus legacy measures in an observational study in systemic sclerosis (SSc). We hypothesized that the PROMIS item banks can be administered in a clinical setting if there is adequate staff support without disrupting the flow of clinic.

METHODS

Patients with SSc in a single academic center completed computerized adaptive test (CAT) administered PROMIS item banks during the clinic visit and legacy measures (using paper and pencil). The construct validity of PROMIS items was evaluated by examining correlations with corresponding legacy measures using multitrait-multimethod analysis.

RESULTS

Participants consisted of 143 SSc patients with an average age of 51.5 years; 71% were female and 68% were white. The average number of items completed for each CAT-administered item bank ranged from 5 to 8 (69 CAT items per patient), and the average time to complete each CAT-administered item bank ranged from 48 seconds to 1.9 minutes per patient (average time = 11.9 minutes/per patient for 11 banks). All correlations between PROMIS domains and respective legacy measures were large and in the hypothesized direction (ranged from 0.61 to 0.82).

CONCLUSION

Our study supports the construct validity of the CAT-administered PROMIS item banks and shows that they can be administered successfully in a clinic with support staff. Future studies should assess the feasibility of PROMIS item banks in a busy clinical practice.

The association of illness perceptions with physical and mental health in systemic sclerosis patients: an exploratory study

OBJECTIVE

The aim of the present study was to evaluate the association between illness perceptions and the ability to cope with physical and mental health problems in a large cohort of systemic sclerosis (SSc) patients.

METHODS

This was a cross-sectional study in 217 systemic sclerosis patients from the Belgian Systemic Sclerosis Cohort. Illness perception and coping were measured by the Revised Illness Perception Questionnaire and a coping questionnaire--the Coping Orientation of Problem Experience inventory (COPE). Physical and mental health-related quality of life was measured by the 36-item short-form health survey (SF-36), as were disease activity and several severity parameters. The relationship between illness perceptions and the ability to cope with physical/mental health problems was examined using multiple linear regression analysis.

RESULTS

According to LeRoy's classification, 49 patients had limited SSc (lSSc), 129 had limited cutaneous SSc (lcSSc) and 39 had diffuse cutaneous SSc (dcSSc). Median disease duration was five years and the modified Rodnan skin score was 4. Good physical health was significantly associated with the lcSSc subtype and low disease activity (p < 0.01 and p < 0.05, respectively). The perception of 'serious consequences' and strong 'illness identity' correlated with poor physical health (p < 0.001). Good mental health was associated with low illness identity scores and low 'emotional response' scores (p < 0.001). Coping variables were less significantly correlated with physical and mental health compared with the illness perception items.

CONCLUSION

Illness representations contribute more than classical disease characteristics to physical and mental health.

The psychological impact of facial changes in scleroderma

The physical disabilities associated with scleroderma are well known but the psychological impact of the condition has received less attention. Few studies have examined appearance related issues, most notably of the face. The aim of this study is to evaluate the psychological impact of facial, aesthetic and functional changes in scleroderma. One hundred seventy-one patients with a clinical diagnosis of scleroderma were recruited into the study. Digital photographs were objectively graded into groups based on severity of disfigurement as judged by an observer. Facial movement was recorded using a modified House-Brackmann Grading Scale. Psychological evaluation comprised the Derriford Appearance Scale short-form (DAS), the Noticeability and Worry score and the Hospital Anxiety and Depression Scale (HADS). Severity of disfigurement predicted decreased mouth opening, the extent to which participants judged their appearance as noticeable to others, and the level of appearance-related concern as measured by the DAS24. There was an inverse relationship with age. Facial changes were ranked as the most worrying aspect of the condition. This study shows facial disfigurement impacts on patient with scleroderma independent of functional changes related to systemic disease. The major difficulty is with the perceived noticeably of the condition to other people and the resulting self-consciousness in social encounters.

Association of gender with clinical expression, quality of life, disability, and depression and anxiety in patients with systemic sclerosis

OBJECTIVES

To assess the association of gender with clinical expression, health-related quality of life (HRQoL), disability, and self-reported symptoms of depression and anxiety in patients with systemic sclerosis (SSc).

METHODS

SSc patients fulfilling the American College of Rheumatology and/or the Leroy and Medsger criteria were assessed for clinical symptoms, disability, HRQoL, self-reported symptoms of depression and anxiety by specific measurement scales.

RESULTS

Overall, 381 SSc patients (62 males) were included. Mean age and disease duration at the time of evaluation were 55.9 (13.3) and 9.5 (7.8) years, respectively. One-hundred-and-forty-nine (40.4%) patients had diffuse cutaneous SSc (dcSSc). On bivariate analysis, differences were observed between males and females for clinical symptoms and self-reported symptoms of depression and anxiety, however without reaching statistical significance. Indeed, a trend was found for higher body mass index (BMI) (25.0 [4.1] vs 23.0 [4.5], p = 0.013), more frequent dcSSc, echocardiography systolic pulmonary artery pressure >35 mmHg and interstitial lung disease in males than females (54.8% vs 37.2%, p = 0.010; 24.2% vs 10.5%, p = 0.003; and 54.8% vs 41.2%, p = 0.048, respectively), whereas calcinosis and self-reported anxiety symptoms tended to be more frequent in females than males (36.0% vs 21.4%, p = 0.036, and 62.3% vs 43.5%, p = 0.006, respectively). On multivariate analysis, BMI, echocardiography PAP>35 mmHg, and anxiety were the variables most closely associated with gender.

CONCLUSIONS

In SSc patients, male gender tends to be associated with diffuse disease and female gender with calcinosis and self-reported symptoms of anxiety. Disease-associated disability and HRQoL were similar in both groups.

The association of body image dissatisfaction and pain with reduced sexual function in women with systemic sclerosis

OBJECTIVE

Pain and body image distress are common among women with SSc, but their relative associations with reduced sexual function have not been assessed. The objective of this study was to assess the independent associations of pain and body image distress with reduced sexual function in women with SSc.

METHODS

Female SSc patients completed measures of sexual function (sexual relationships subscale of the Psychosocial Adjustment to Illness Scale-Self-Report), body image dissatisfaction (Satisfaction with Appearance Scale) and pain (visual analogue scale). Multiple regression analysis was used to assess the associations of body image dissatisfaction and pain with reduced sexual function, controlling for sociodemographic and disease variables.

RESULTS

The sample included 117 female SSc patients [33 (28.2%) diffuse; mean age 51.4 (11.9) years; mean time since diagnosis 9.1 (8.5) years]. Unadjusted analyses found that reduced sexual function was associated with pain (r = 0.44, P < 0.001), body image dissatisfaction (r = 0.35, P < 0.001) and being married (r = 0.34, P < 0.001). In multivariate linear regression, disease duration (β = 0.17, P = 0.046), pain (β = 0.29, P = 0.001) and unmarried status (β = -0.23, P = 0.006) were independently associated with reduced sexual function. Dissatisfaction with appearance was not significantly associated with reduced sexual function (β = 0.16, P = 0.067).

CONCLUSION

Pain is an important indicator of sexual function among women with SSc. Body image dissatisfaction was not independently associated with sexual impairment and appears to be less important factor than pain in determining sexual function. Future research should focus on isolating specific sources of pain that may be amenable to intervention in order to improve sexual function.

Mood and anxiety disorders in systemic sclerosis patients

OBJECTIVE

To assess the prevalence of mood and anxiety disorders in systemic sclerosis (SSc) patients and the association of these disorders with clinical features.

METHODS

Between May 2002 and May 2004, 100 SSc patients fulfilling the American Rheumatism Association and/or Leroy & Medsger criteria were recruited: 51 were from a SSc patient association meeting, and 49 were hospitalized in an internal medicine department and recruited consecutively. Mood and anxiety disorders were assessed by use of a structured clinical interview [the Mini International Neuropsychiatric Interview (MINI)] performed by a psychiatrist and a self-reporting questionnaire [the Hospital Anxiety and Depression Scale (HADS)]. On the same day, psychiatric treatment and clinical features were recorded by a physician.

RESULTS

As assessed by the MINI, 19% [95% confidence interval 12-28%] of all SSc patients were currently experiencing a major depressive episode (MDE), 56% [46-65%] had a lifetime history of MDE and 14% [8-22%] had current dysthymia. Current MDE was more prevalent among hospitalized patients than among other patients (28% versus 10%, p=0.02). Specific anxiety disorders were diagnosed in 37 [28-47] patients. Less than 50% of the patients with mood disorders received psychiatric treatment. Patients with or without current depression did not differ in clinical symptoms of SSc, except for digestive symptoms.

CONCLUSION

The current and lifetime prevalence of major depression and anxiety disorders is high in SSc patients, especially during hospitalization. However, only half of such patients receive adequate psychiatric treatment. Therefore, a better assessment of psychiatric disorders in SSc patients is needed.

Assessment of depressive symptoms during post-transplant follow-up care performed via telehealth

Telehealth provides a successful medium for the treatment of depression and other mental health illnesses. Often, inadequate treatment for this condition is found in patients with chronic co-morbid conditions such as those presented by the transplant recipient, a population at risk for depression. One concern of healthcare providers is the inability to adequately screen for symptoms of depression. This secondary analysis describes depression screening of 138 transplant recipients receiving follow-up care via telehealth (TH) and standard care (SC) as part of a larger National Institute of Nursing Research-funded randomized clinical trial. Of subjects who consented, 70 (51%) were randomized to the TH portion of the study. Depressive symptoms were measured by the Center for Epidemiologic Studies-Depression (CES-D) survey at study entry and at 6 and 12 months postconsent into the study. Univariate and subgroup analyses using SAS found no differences between the TH (n = 70) and SC (n = 68) group for demographic and social characteristics. No differences in CES-D scores were found between TH and SC groups. The concern in adding distance in the care of this medically fragile population was not substantiated in this study.

Systemic sclerosis as a model of chronic rejection in facial composite tissue transplantation

INTRODUCTION

Chronic rejection remains a potential significant long-term problem of facial allograft transplantation. Scleroderma parallels chronic rejection in terms of its immunological pathophysiology and its histopathological processes. Through the analysis of facial changes in scleroderma we demonstrate how chronic facial allograft rejection may present and progress.

METHODS

129 consecutive patients with a clinical diagnosis of scleroderma were recruited into the study. Static facial disease assessment was carried out through the analysis of digital photographs. Facial motion dysfunction was assessed using a modified House-Brackmann Grading Scale and an established maximal static response assay. Psychological evaluation comprised the Derriford Appearance Scale short-form (DAS), the Noticeability and Worry score and the Hospital Anxiety and Depression Scale (HADS).

RESULTS

Static disease severity as measured using an observer-rated disfigurement scale revealed all grades of disease in the scleroderma cohort - from mild through to severe. Significant positive correlations were seen between observer rated disfigurement and DAS24, Noticeability and Worry scores. No significant relationship could be seen between the indices of facial motion impairment and psychological scores.

CONCLUSIONS

Progressive facial deterioration seen over time in scleroderma provides a comprehensive spectrum of static and dynamic facial changes which may be encountered in chronic facial graft rejection. This study provides valuable insight into the potentially significant long-term sequelae of allogenic reconstructive transplantation.

(Not) talking about sex: a systematic comparison of sexual impairment in women with systemic sclerosis and other chronic disease samples

OBJECTIVE

Sexual impairment in women with SSc has received little attention. The objective of this study was to compare levels of sexual impairment in women with SSc with samples of women with medical illnesses for which sexual impairment has been researched more extensively.

METHODS

SSc patients completed the Sexual Relationships subscale of the Psychosocial Adjustment to Illness Scale-Self-Report (PAIS-SR). A systematic review was conducted to select comparison samples. Sexual Relationships subscale scores from SSc patients were compared with scores from comparison samples (breast or gynaecological cancer and HIV) using t-tests and Hedges's g to calculate effect sizes.

RESULTS

Samples from 138 female SSc patients were analysed (28.3% diffuse; mean age 52.1 +/- 12.3 years; mean time since diagnosis 9.0 +/- 8.3 years). Women with dcSSc (6.1 +/- 4.2) reported significantly greater sexual impairment (P < 0.05) than those with lcSSc (4.4 +/- 4.2), three breast cancer samples (1.8 +/- 0.1, 3.4 +/- 3.9, 1.6 +/- 0.6) and two samples of HIV-positive female patients (4.4 +/- 3.8, 4.5 +/- 3.9). Scores in dcSSc were similar to one sample of HIV-positive women (5.8 +/- 4.1) and gynaecological cancer patients (7.3 +/- 4.3). Scores in lcSSc were significantly higher than two breast cancer samples, similar to one breast cancer sample and two HIV-positive samples, and significantly lower (P < 0.05) than in one HIV sample and gynaecological cancer.

CONCLUSION

Women with SSc, particularly those with dcSSc, have high levels of sexual impairment compared with women with other chronic diseases, where sexual function has received greater attention. Further research is needed on sexual function among women with SSc.

Cerebral Vasculopathy Is Associated with Severe Vascular Manifestations in Systemic Sclerosis

Objective.

To investigate brain involvement in patients with systemic sclerosis (SSc).

Methods.

Sixty-three patients with SSc fulfilling the American College of Rheumatology and/or Leroy and Medsger criteria were retrospectively studied, including 30 (47.6%) with limited cutaneous and 27 (42.9%) with diffuse cutaneous SSc. Forty-one patients underwent computed tomography (CT) scan and magnetic resonance imaging (MRI) of the brain, 11 patients only CT scan, and the remaining 11 patients only MRI. Cerebral vasculopathy on MRI and CT scan was defined as absent or mild (score < 1), moderate (1 ≤ score < 2), or severe (score ≥ 2) on a 4-point scale (0 to 3).

Results.

Cerebral vasculopathy was identified on CT scan in 22 patients (moderate in 12 and severe in 10) and on MRI in 38 patients (moderate in 28 and severe in 10). Patients with severe cerebral vasculopathy seen on MRI were more likely to have pulmonary arterial hypertension (PAH; p = 0.003) and showed a tendency to have scleroderma renal crisis (SRC; p = 0.25, test for trend p = 0.097). A similar association was found between severe cerebral vasculopathy seen on CT scan and PAH (p = 0.026) or SRC (p = 0.04). After adjusting for age and hypertension, severe cerebral vasculopathy was still associated with increased risk of severe vascular manifestations [odds ratio (OR) 32, 95% confidence interval (CI) 3.45–297, p = 0.002 for CT scan; OR 26, 95% CI 1.71–394, p = 0.019 for MRI].

Conclusion.

Severe cerebral vasculopathy is associated with severe vascular manifestations in SSc patients. SSc patients with severe vascular complications should undergo neuroradiological imaging assessment of brain involvement.

Fatigue: an overlooked determinant of physical function in scleroderma

OBJECTIVES

To examine the frequency and correlates of fatigue and its impact on physical and social functioning in patients with scleroderma, and to investigate whether fatigue mediates an association between pain and physical function.

METHODS

One hundred and seven scleroderma patients attending an academic scleroderma specialty centre completed measures of fatigue, sleep, pain, depressive symptoms, and physical and social functioning. Patients had received a comprehensive clinical assessment with a diagnosis of limited or diffuse scleroderma from their attending rheumatologist.

RESULTS

In this sample of scleroderma patients, 76% reported experiencing fatigue and 61% of these patients reported fatigue as one of their three most distressing symptoms. Patients endorsing greater pain had higher levels of self-reported fatigue, as did those reporting greater depression and poorer functioning. Multiple regression analyses indicated that global fatigue was a significant cross-sectional correlate of physical, but not social, functioning after controlling for depressive symptoms, level of education, poor sleep quality and disease subtype. However, global fatigue did not predict physical function when pain was included in the analyses.

CONCLUSIONS

Our findings indicate that fatigue is common in scleroderma and that pain and fatigue are significant determinants of physical functioning for patients with limited and diffuse disease subtypes. Future research should investigate whether effective pain treatments reduce symptoms of fatigue, as well as identify other possible causes of fatigue in order to improve quality of life for scleroderma patients.

Reliability and validity of the center for epidemiologic studies depression scale in patients with systemic sclerosis

OBJECTIVE

Reported rates of depressive symptoms in patients with systemic sclerosis (SSc) are high. No depression assessment tools, however, have been validated for patients with SSc. Our objective was to assess the internal consistency reliability, convergent validity, and structural/construct validity of the Center for Epidemiologic Studies Depression Scale (CES-D) in patients with SSc.

METHODS

We conducted a cross-sectional, multicenter study of 470 SSc patients. Internal consistency reliability was assessed with Cronbach's alpha and structural/construct validity with confirmatory factor analysis.

RESULTS

Internal consistency reliability was good for the overall CES-D scale (alpha = 0.88) and for its 4 factors (alpha = 0.67-0.88). Correlations of the CES-D total score were -0.73 with mental health, -0.36 with physical health, 0.41 with disability, and 0.44 with pain. The 4-factor model originally found in the general population and validated for patients with rheumatoid arthritis (depressed affect, somatic/vegetative, [lack of] positive affect, and interpersonal factors) fit the data well, as did a second-order version of the same model with an overarching depression factor that loaded onto each of the 4 first-order factors. The 4-factor model fit the SSc data better than alternative models.

CONCLUSION

Internal consistency reliability and convergent validity were good, the 4-factor structure reported in the general population was replicated, and a second-order model with an overarching depression factor fit well. These findings indicate that the CES-D is a valid and reliable measure of depressive symptoms for patients with SSc.

Become your own advocate: advice from women living with scleroderma

PURPOSE

Systemic sclerosis (SSC) affects 300,000 people in the USA and has a significant effect on an individual's functional ability. The purpose of this study was to outline the key components of living with the illness and to identify the information that those who are newly diagnosed would need to initiate a successful course of disease self-management. The results will provide the groundwork for development and testing of a self-paced education program for patients with SSC.

METHOD

Focus groups were conducted with 11 women diagnosed with SSC.

RESULTS

Analysis of the transcripts yielded three themes, Secure Effective Medical Management, Live Your Life, and Learn Everything You Can. The thread Become Your Own Advocate wove these three themes together and illustrated that taking control of SSC is ultimately a function of self-advocacy.

CONCLUSION

For patients with SSC, taking control of their illness was a necessary component of maintaining the highest quality of life possible. A positive attitude, a strong support system, a commitment to moving forward with life, and access to high-quality, timely information all provided the participants with the tools to develop and implement a strategy of self-advocacy in disease management.
