Effectiveness of Nonpharmacologic Interventions in Systemic Sclerosis: A Systematic Review

Systematic literature review informing the EULAR recommendations for the non-pharmacological management of systemic lupus erythematosus and systemic sclerosis

Through this systematic literature review, we assembled evidence to inform the EULAR recommendations for the non-pharmacological management of systemic lupus erythematosus (SLE) and systemic sclerosis (SSc). We screened articles published between January 2000 and June 2021. Studies selected for data extraction (118 for SLE and 92 for SSc) were thematically categorised by the character of their intervention. Of 208 articles included, 51 were classified as robust in critical appraisal. Physical activity was the most studied management strategy and was found to be efficacious in both diseases. Patient education and self-management also constituted widely studied topics. Many studies on SLE found psychological interventions to improve quality of life. Studies on SSc found phototherapy and laser treatment to improve cutaneous disease manifestations. In summary, non-pharmacological management of SLE and SSc encompasses a wide range of interventions, which can be combined and provided either with or without adjunct pharmacological treatment but should not aim to substitute the latter when this is deemed required. While some management strategies i.e., physical exercise and patient education, are already established in current clinical practice in several centres, others e.g., phototherapy and laser treatment, show both feasibility and efficacy, yet require testing in more rigorous trials than those hitherto conducted.

Physical Therapy in Systemic Sclerosis: The Patient Perspective

OBJECTIVE

To assess the use, satisfaction, needs, and preferences regarding physical therapy (PT) in patients with systemic sclerosis (SSc).

METHODS

A total of 405 SSc patients, treated in the Leiden University Medical Center multidisciplinary care program and fulfilling American College of Rheumatology (ACR)/European Alliance of Associations for Rheumatology (EULAR) 2013 SSc criteria, received a questionnaire containing 37 questions on use and satisfaction regarding PT over a 2-year period, and their needs and preferences for future PT.

RESULTS

A total of 204 SSc patients (median age 63 years, 81% female) completed the questionnaire. One hundred twenty-eight patients (63%) had used or were using PT in a primary care setting. For 39% of patients not using PT, lack of referral or lack of knowledge was the reason for not using it. The most frequently reported active treatments were muscle-strengthening (n = 92 [72%]), range of motion (n = 77 [60%]), and aerobic exercises (n = 72 [56%]). Specific SSc hand- and mouth-opening exercises were reported by 20 (15%) and 7 (6%) patients, respectively. Manual treatment (massage or passive mobilization) was reported by 83 patients (65%). The mean ± SD satisfaction score (range 0-10) was 8.2 ± 1.6. Regarding patients' needs, 96 patients (47%) of the total group wanted to receive more information concerning PT, and 128 (63%) wanted to continue, start, or restart PT in the near future, with 56 of the 128 patients (44%) favoring individual treatment on a continuous basis.

CONCLUSION

We observed a significant variation in the use and content of PT for SSc patients in a primary care setting. Our results suggest potential underuse of PT care, in particular for hand and oral dysfunction, and underpin the need for initiatives to improve the quality and accessibility of PT care for SSc patients.

Randomized controlled trial of an internet-based self-guided hand exercise program to improve hand function in people with systemic sclerosis: the Scleroderma Patient-centered Intervention Network Hand Exercise Program (SPIN-HAND) trial

BACKGROUND

Systemic sclerosis (scleroderma; SSc) is a rare autoimmune connective tissue disease. Functional impairment of hands is common. The Scleroderma Patient-centered Intervention Network (SPIN)-HAND trial compared effects of offering access to an online self-guided hand exercise program to usual care on hand function (primary) and functional health outcomes (secondary) in people with SSc with at least mild hand function limitations.

METHODS

The pragmatic, two-arm, parallel-group cohort multiple randomized controlled trial was embedded in the SPIN Cohort. Cohort participants with Cochin Hand Function Scale (CHFS) scores ≥ 3 and who indicated interest in using the SPIN-HAND Program were randomized (3:2 ratio) to an offer of program access or to usual care (targeted N = 586). The SPIN-HAND program consists of 4 modules that address (1) thumb flexibility and strength; (2) finger bending; (3) finger extension; and (4) wrist flexibility and strength. The primary outcome analysis compared CHFS scores 3 months post-randomization between participants offered versus not offered the program. Secondary outcomes were CHFS scores 6 months post-randomization and functional health outcomes (Patient-Reported Outcomes Measurement Information System profile version 2.0 domain scores) 3 and 6 months post-randomization.

RESULTS

In total, 466 participants were randomized to intervention offer (N = 280) or usual care (N = 186). Of 280 participants offered the intervention, 170 (61%) consented to access the program. Of these, 117 (69%) viewed at least one hand exercise instruction video and 77 (45%) logged into the program website at least 3 times. In intent-to-treat analyses, CHFS scores were 1.2 points lower (95% CI - 2.8 to 0.3) for intervention compared to usual care 3 months post-randomization and 0.1 points lower (95% CI - 1.8 to 1.6 points) 6 months post-randomization. There were no statistically significant differences in other outcomes.

CONCLUSION

The offer to use the SPIN-HAND Program did not improve hand function. Low offer uptake, program access, and minimal usage among those who accessed the program limited our ability to determine if using the program would improve function. To improve engagement, the program could be tested in a group format or as a resource to support care provided by a physical or occupational therapist.

Exploring the effects of a combined exercise programme on pain and fatigue outcomes in people with systemic sclerosis: study protocol for a large European multi-centre randomised controlled trial

Background

Pain, related to Raynaud’s phenomenon or digital ulceration, has been identified as very prevalent and debilitating symptoms of systemic sclerosis (SSc), both significantly affecting patients’ quality of life (QoL). Pharmacological therapeutic strategies were found not to be sufficiently effective in the management of SSc-induced pain and fatigue, and evidence for exercise is scarce. As yet, the effects of a long-term, tailored exercise programme on pain and fatigue in patients with SSc have not been explored. In addition to pain and fatigue, this study aims to evaluate the effects of exercise on QoL, physical fitness, functional capacity, and vascular structure in people with SSc (PwSSc).

Methods

This will be a multicentre (n = 6) randomised controlled clinical trial to assess the effect of a previously established, supervised 12-week combined exercise programme on pain and fatigue as compared to no exercise in PwSSc. The study will recruit 180 patients with SSc that will be allocated randomly to two groups. Group A will perform the exercise programme parallel to standard usual care and group B will receive usual care alone. Patients in the exercise group will undertake two, 45-min sessions each week consisting of 30-min high-intensity interval training (HIIT) (30-s 100% peak power output/30-s passive recovery) on an arm crank ergometer and 15 min of upper body circuit resistance training. Patients will be assessed before as well as at 3 and 6 months following randomisation. Primary outcomes of the study will be pain and fatigue assessed via questionnaires. Secondary outcomes include quality of life, structure of digital microvasculature, body composition, physical fitness, and functional capacity.

Discussion

Data from this multi-centre research clinical trial will primarily be used to establish the effectiveness of a combined exercise protocol to improve pain and fatigue in SSc. In parallel, this study will be the first to explore the effects of long-term exercise on potential microvascular alterations assessed via NVC. Overall, this study will provide sufficient data to inform current clinical practice guidelines and may lead to an improvement of QoL for patients with SSc.

Body image as a multidimensional concept: A systematic review of body image facets in eating disorders and muscle dysmorphia

Body image disturbance is core to the psychopathology of eating disorders (EDs), and related disorders such as muscle dysmorphia (MD). Global measures of body image fail to quantify specific aspects of body image disturbance that characterizes EDs, and may be differentially associated to outcomes. The aim of this systematic review was to provide an overview of specific body image facets and synthesize findings from controlled studies that compared clinical ED/MD and control-comparison groups in body image disturbance. One-hundred sixty-seven studies met inclusion criteria, and reported on comparisons among 30,584 individuals in 28 body image facets, which were more broadly grouped into evaluative, perceptual, cognitive-affective and motivational categories for the purpose of the present review. Effect sizes were calculated as Cohen's d for every comparison between ED and control groups. Body dissatisfaction (evaluative category) was the most prevalent facet assessed across studies (62 %), and differences between clinical and control groups were the largest in this category, especially for bulimia nervosa (d = 1.37). Scarcity of studies with male and MD clinical samples, and use of single-item and non-validated measures, should encourage development of instruments for body image facets pertinent to EDs and MD that can be validly applied across gender.

How do different interventions impact stair climbing? A systematic review and meta-analysis

OBJECTIVES

This study aimed to analyze the effect of interventions to increase stair use.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

An online search was conducted in January 2021 in five databases (Web of Science, SPORTDiscus, MedLine/PubMed, PsycINFO, and CINAHL). Experimental studies (randomized and non-randomized) conducted in adults, which provided stair use measures with pre- and post-intervention periods were included. A random-effect meta-analysis, as well as subgroup analyses were conducted to evaluate the quantitative effect of interventions on stair use.

RESULTS

Overall, 34 studies were included in qualitative analyses, and 15 in the meta-analysis. Most of the studies were conducted in Europe and private settings (e.g., office buildings). Overall, interventions increased stair use in adults (odds ratio (OR) 1.48; 95% confidence intervals (CI) 1.38-1.58; I2 = 99.6%). Subgroup analyses showed that interventions increased stair use regardless of the continent and observer type (manual or electronic). However, different settings (shopping malls and office buildings), as well as studies (time of intervention) and intervention characteristics (sign size and location, message characters) were associated with increased stair use.

CONCLUSIONS

Different interventions can increase stair use in several continents and settings. Sign and message characteristics should be considered when designing interventions or policies to promote physical activity by increasing stair use.

Rehabilitation Interventions in Systemic Sclerosis: A Systematic Review and Future Directions

OBJECTIVE

To systematically review evidence of rehabilitation interventions for improving outcomes in systemic sclerosis (SSc) and to evaluate evidence quality.

METHODS

Several electronic databases were searched to identify studies in which rehabilitation professionals delivered, supervised, or participated in interventions for individuals with SSc. Randomized controlled trials (RCTs) or non-randomized trials, one-arm trials, and prospective quasi-experimental studies with interventions were included if they had ≥10 participants. Quality appraisal was conducted by 2 independent raters using the Physiotherapy Evidence Database (PEDro) Scale.

RESULTS

A total of 16 good or excellent quality studies (15 RCTs, 1 prospective quasi-experimental study) were included. Most rehabilitation interventions focused on hands/upper extremities, followed by multicomponent, orofacial, and directed self-management. Sample sizes varied between 20-267 participants (median 38). In 50% of studies, participants in intervention groups significantly improved compared to controls. Most studies demonstrated within-group improvements in intervention groups. Interventions varied in content, delivery, length, and dose and outcome measures collected.

CONCLUSION

Existing evidence provides some support for rehabilitation in SSc, such as interventions that focus on hand and upper extremity outcomes or are multicomponent, although there is high study heterogeneity. The evidence base would benefit from interventions testing similar replicable components, use of common outcome measures, and incorporation of delivery modes that enable larger sample sizes. There are challenges in recruiting participants due to the rarity of SSc and high disease burden, as participants' involvement in rehabilitation studies requires active participation over time. Intervention studies designed to reduce participation barriers may facilitate translation of effective interventions into practice.

Non-operatively managed blunt and penetrating renal trauma: Does early follow up CT scan change management? A systematic review

BACKGROUND

Renal injury accounts for 1-5% of all traumatic injuries. Non-operative management (NOM) of renal trauma has demonstrated higher renal salvage rates and reduced morbidity.

AIMS

The aim of this review is to clarify the indications of early follow up CT scan for adult patients, with NOM, renal trauma, with a view to avoiding unnecessary CT scanning and radiation exposure in this cohort of patients.

METHODS

A systematic search was conducted using PubMed (MEDLINE), Web of Science, Embase, and Cochrane library, with references from relevant articles also evaluated. Inclusion criteria were defined as studies reporting outcomes of patients ≥12 years of age, with NOM, renal trauma and early CT re-imaging. The outcomes of interest were renal complications requiring intervention, specifically collecting system and vascular complications.

RESULTS

Five studies met the inclusion criteria. In total, 542 patients were included in this analysis; study sizes ranged from 48 to 207 patients. Early re-imaging was performed for 510 patients, including 489 CTs and 31 Ultrasounds (US). Mean time to re-imaging ranged from 1 - 35.9 days. Twenty three patients required intervention following re-imaging, all of which were for injuries grade ≥ 3 and presented with clinical deterioration prior to re-imaging, had a collecting system injury identified on initial CT scan or both. The number needed to re-image, in order to change the management of one patient, was 22.

CONCLUSIONS

Although the findings of this review are based on retrospective data, they suggest routine early re-imaging can be safely omitted for all NOM, renal injuries which remain asymptomatic, with no collecting system injury diagnosed on initial CT, provided appropriate delayed phase imaging is available. Future prospective studies are required to further clarify the indications of early re-imaging, specifically for NOM penetrating injuries, and the appropriate modality and timing of early re-imaging for all NOM renal trauma.

Joint mobilization and therapeutic exercises in the hands of patients with systemic sclerosis: A preliminary randomized controlled trial

OBJECTIVE

To investigate the effectiveness of Maitland's joint mobilization and therapeutic exercises on the functionality of the hands in patients with systemic sclerosis.

DESIGN

Randomized controlled trial.

SETTING

Tertiary university hospital.

SUBJECTS

Twenty-four patients diagnosed with systemic sclerosis according to ACR/EULAR 2013 criteria; age ⩾18 years and Cochin Hand Functional Scale (COCHIN) score ⩾10. They were randomized to physical therapy group (n = 12) or control group (n = 12).

INTERVENTIONS

The physical therapy group received joint mobilization and undertook therapeutic exercises, twice a week, for 12 weeks, and received a booklet with information about the disease. The control group only received the booklet about the disease.

MAIN MEASURES

The primary outcome measure was functionality of the hands (COCHIN). The secondary outcomes measures were disability (SHAQ), pain (visual analogic scale), range of motion (HAMIS and Delta finger-to-palm), grip strength (JAMAR dynamometer), and quality of life (SF12).

RESULTS

Twenty-two patients were female, with a mean age of 47.4 ± 11.1 years and 18 had limited cutaneous form. The physical therapy group showed a decrease of 11.33 points in the COCHIN in comparison with the control group (P = 0.09). There was a significant increase in range of motion by HAMIS (3.00 ± 1.48 vs 5.42 ± 2.64, P = 0.008), reduction in pain VAS (3.42 ± 2.78 vs 7.75 ± 2.53, P < 0.001), and increase in the physical component of SF12 (38.51 ± 9.60 vs 32.65 ± 9.10, P = 0.038).

CONCLUSION

Maitland's joint mobilization and therapeutic exercises improved the functionality of the hands, reduced pain in the hands and wrists, increased range of motion, and improved quality of life in patients with systemic sclerosis.

French recommendations for the management of systemic sclerosis

Systemic sclerosis (SSc) is a generalized disease of the connective tissue, arterioles, and microvessels, characterized by the appearance of fibrosis and vascular obliteration. There are two main phenotypical forms of SSc: a diffuse cutaneous form that extends towards the proximal region of the limbs and/or torso, and a limited cutaneous form where the cutaneous sclerosis only affects the extremities of the limbs (without passing beyond the elbows and knees). There also exists in less than 10% of cases forms that never involve the skin. This is called SSc sine scleroderma. The prognosis depends essentially on the occurrence of visceral damage and more particularly interstitial lung disease (which is sometimes severe), pulmonary arterial hypertension, or primary cardiac damage, which represent the three commonest causes of mortality in SSc. Another type of involvement with poor prognosis, scleroderma renal crisis, is rare (less than 5% of cases). Cutaneous extension is also an important parameter, with the diffuse cutaneous forms having less favorable prognosis.

Role and effectiveness of complex and supervised rehabilitation on overall and hand function in systemic sclerosis patients-one-year follow-up study

The aim of this study was to estimate the long-term results of complex and supervised rehabilitation of the hands in systemic sclerosis (SSc) patients. Fifty-one patients were enrolled in this study: 27 patients (study group) were treated with a 4-week complex, supervised rehabilitation protocol. The control group of 24 patients was prescribed a home exercise program alone. Both groups were evaluated at baseline and after 1-, 3-, 6-, and 12-months of follow-up with the Disability of the Arm, Shoulder and Hand Questionnaire (DAHS) as the primary outcome, pain (VAS—visual analog scale), Cochin Hand Function Scale (CHFS), Health Assessment Questionnaire Disability Index (HAQ-DI), Scleroderma-HAQ (SHAQ), range of motion (d-FTP—delta finger to palm, Kapandji finger opposition test) and hand grip and pinch as the secondary outcomes. Only the study group showed significant improvements in the DASH, VAS, CHFS and SHAQ after 1, 3 and 6 months of follow-up (P = 0.0001). Additionally, moderate correlations between the DASH, CHFS and SHAQ (R = 0.7203; R = 0.6788; P = 0.0001) were found. Complex, supervised rehabilitation improves hand and overall function in SSc patients up to 6 months after the treatment but not in the long term. The regular repetition of this rehabilitation program should be recommended every 3–6 months to maintain better hand and overall function.

Effects of supervised exercise program and home exercise program in patients with systemic sclerosis: A randomized controlled trial

AIM

To compare the effects of supervised exercise and home exercise program in patients with systemic sclerosis (SSc).

METHODS

Thirty-seven SSc patients were included. Patients with SSc were allocated into 2 groups as supervised and home exercise. Breathing, aerobic and resistance exercises were performed with a physiotherapist for 12 weeks in the supervised exercise group. Breathing, posture and aerobic exercises were given to the home exercise group as a home program for 12 weeks. All patients were assessed at baseline and 12 weeks later in terms of functional capacity, pulmonary functions, respiratory-peripheral muscle strength, dyspnea severity, health-related quality of life (HRQoL) and fatigue level.

RESULTS

Significant improvements were observed in the functional capacity, measured by 6 minute walking test in the supervised exercise group (before = 376.21 ± 65.50, after = 518.78 ± 75.84 m) and home exercise group (before = 384.44 ± 68.14, after = 432.7 ± 70.8 m; (P < .05). Respiratory-peripheral muscle strength (with the exception of inspiratory muscle strength and upper limb strength in the home exercise group) and HRQoL were significantly increased and fatigue level was significantly decreased in the supervised exercise and home exercise groups (P < .05). However, pulmonary functions and dyspnea severity were significantly improved only in the supervised exercise group (P < .05). The supervised exercise program was found superior to the home exercise program for change in all parameters (P < .05).

CONCLUSION

This study suggests that exercise interventions should be applied in addition to the medical treatments of patients with SSc as supervised and home exercise programs play an important role in the functionality and health status of these patients.

Evidence and consensus-based recommendations for non-pharmacological treatment of fatigue, hand function loss, Raynaud's phenomenon, and digital ulcers in patients with systemic sclerosis

OBJECTIVE

Systemic sclerosis is a complex connective tissue disease affecting mental and physical health. Fatigue, hand function loss, and Raynaud's phenomenon are the most prevalent disease-specific symptoms of systemic sclerosis. This study aimed to develop consensus and evidence-based recommendations for non-pharmacological treatment of these symptoms.

METHODS

A multidisciplinary task force was installed comprising 20 Dutch experts. After agreeing on the method for formulating the recommendations, clinically relevant questions about patient education and treatments were inventoried. During a face-to-face task force meeting, draft recommendations were generated through a systematically structured discussion, following the nominal group technique. To support the recommendations, an extensive literature search was conducted in MEDLINE and six other databases until September 2020, and 20 key systematic reviews, randomized controlled trials, and published recommendations were selected. Moreover, 13 Dutch medical specialists were consulted on non-pharmacological advice regarding Raynaud's phenomenon and digital ulcers. For each recommendation the level of evidence and the level of agreement was determined.

RESULTS

Forty-one evidence and consensus-based recommendations were developed, and 34, concerning treatments and patient education of fatigue (12), hand function loss (8), and Raynaud's phenomenon/digital ulcers-related problems (14), were approved by the task force.

CONCLUSIONS

These 34 recommendations provide guidance on non-pharmacological treatment of three of the most frequently described symptoms in patients with systemic sclerosis. The proposed recommendations can guide referrals to health professionals, inform the content of non-pharmacological interventions, and can be used in the development of national and international postgraduate educational offerings.

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.

Intensive and App-Delivered Occupational Therapy to Improve Upper Extremity Function in Early Diffuse Cutaneous Systemic Sclerosis: A Pilot Two-Arm Trial

OBJECTIVE

Systemic sclerosis (SSc) reduces upper extremity function and performance of everyday activities; however, there are few evidence-based rehabilitation interventions. This study examined short and longer-term effects of two occupational therapy interventions on hand disability.

METHODS

Participants with diffuse cutaneous SSc were randomized to one of two 18-week interventions: Intensive group, receiving 8-weekly in-person occupational therapy sessions with App-delivered home exercises, or App alone group. The primary outcome was QuickDASH hand disability; secondary outcomes were physical function (PROMIS scale), and total active hand motion. Linear mixed models were used to examine treatment effects.

RESULTS

Most participants were female (72%); the mean age was 52 years ± 13.4 (n = 32). There were no significant between-group effects on QuickDASH (p = 1.0; mean change -6.4 on 0-100 scale in both groups at 18 weeks). Left lateral pinch, an exploratory outcome, improved in App alone compared to Intensive from baseline to 18 weeks. Within groups, the intensive group had the largest improvements after 8 weeks (-8.5 on QuickDASH; p = 0.03), but then lost gains from 8 to 18 weeks while the App alone group had modest improvements from baseline to 8 weeks, but then continued to improve. Of completers, 50% had clinically meaningful improvement on QuickDASH in the Intensive group and 64% had improvement in App alone.

CONCLUSION

Both interventions showed beneficial effects on hand disability. Participants in the App alone group improved equally to the Intensive group at 18 weeks. Our findings provide support for further study into telehealth rehabilitation approaches.

Self-management interventions in systemic sclerosis: A systematic review

Systemic sclerosis is a rare and incurable autoimmune disease in which patients are challenged with self-managing their disease. Systematic evaluation of the essential self-management intervention components and self-management outcomes is necessary to assess the state of the science of self-management for patients with systemic sclerosis. As such, the purpose of this systematic review was to identify and describe self-management interventions and their impact on self-management outcomes in adults with systemic sclerosis. Studies were included if they contained a self-management intervention, incorporated at least one self-management outcome identified as a common data element by the National Institute of Nursing Research (i.e., patient activation, self-efficacy, self-regulation, global health), and were conducted in adults with systemic sclerosis. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, PubMed, Cumulative Index of Nursing and Allied Health Literature, and Embase were searched from the inception of each database to March 2020, yielding a total of 215 studies. Of these reports, 16 met the inclusion criteria for this review. There was notable variability in the types of self-management interventions and their effects on key self-management outcomes. Self-management interventions focused on improving physical function through rehabilitation programs were the most common interventions (n = 7). The poor methodological quality of the studies included in this systematic review, however, limited the synthesis of and recommendations for self-management interventions in adults with systemic sclerosis. Future research in systemic sclerosis should include key self-management outcomes in larger, more rigorously designed studies to allow for comparisons across studies and to advance the science of self-management.

Effect of a tailored home-based exercise program in patients with systemic sclerosis: A randomized controlled trial

OBJECTIVE

The aim was to evaluate the effect of a home-based exercise program on functional capacity, health-related quality of life (HRQoL), and disability, in patients with systemic sclerosis (SSc).

METHODS

A 6-month randomized controlled trial was conducted on SSc patients by comparing a home-based minimally supervised exercise program (exercise on a stationary cycle and strengthening of upper limbs; stretching of the hands) with usual care. At baseline and after 3 and 6 months, the patients underwent: 6 minutes walking test; hand mobility in scleroderma test; maximal exercise test on an ergocycle; strength measures (handgrip, quadriceps, and biceps). HRQoL (short-form 36 [SF-36]) and disability (health assessment questionnaire disability index [HAQ-DI]) were measured at the same time.

RESULTS

Forty-four patients participated in the study. Twenty-two were randomly assigned to the intervention group (IG, mean age 63.60 ± 10.40 years) and 22 to the control group (CG, 61.80 ± 14.40 years). At 6 months, the distance walked in 6 minutes increased by 46 m (baseline 486, 95% CI 458-513 m; 6 months 532, 95% CI 504-561 m) in IG, whereas it decreased by 5 m (baseline 464, 95% CI 431-497 m; 6 months 459, 95% CI 427-490 m) in CG with a significantly different temporal trend at the between-groups comparison (P < .001). An improvement was also observed for strength measures (handgrip, P = .003; quadriceps, P < .001; biceps, P < .001), for the SF-36 physical component score (P < .001) and for the HAQ-DI (P = .011).

CONCLUSIONS

This study indicates that in SSc patients, a minimally supervised home-based exercise program improves physical performance, quality of life, and disability in comparison with usual care.

Room for improvement in non-pharmacological systemic sclerosis care? - a cross-sectional online survey of 650 patients

BACKGROUND/ OBJECTIVE

To gain insight in the use of current systemic sclerosis (SSc) care provided by health professionals from the patient perspective. We focused on referral reasons, treatment goals, the alignment with unmet care needs, and outcome satisfaction.

METHODS

Dutch SSc patients from 13 participating rheumatology departments were invited to complete an online survey. Descriptive statistics were used to describe current use of non-pharmacological care and outcome satisfaction. Reasons for referral and treatment goals were encoded in International Classification of Function and Disability (ICF) terms.

RESULTS

We included 650 patients (mean (standard deviation [SD]) age, 59.4 (11.4) years. 50% had contact with a health professional in the past year; 76.3% since disease onset. Physiotherapists were the most frequently visited in the past year (40.0%), followed by dental hygienists (11.4%) and podiatrists (9.2%). The three most common referral reasons were pain, joint mobility and cardiovascular functions. Fatigue, Raynaud's phenomenon, physical limitations, reduced hand function and joint problems were mentioned by more than 25% of all respondents as unmet needs. The proportion of patients treated in the past year by a health professional who were satisfied with knowledge and expertise of their health professionals was 74.4%; 73% reported improved daily activities and better coping with complaints. However, 48.9% perceived that the collaboration between rheumatologist and health professional was never or only sometimes sufficient.

CONCLUSION

Despite the high outcome satisfaction and good accessibility of health professionals, there are obstacles in the access to non-pharmacological care and communication barriers between health professionals and rheumatologists.

Lymphology and translational medicine

Lymphology is evolving in search of a better management of lymphedema patients, both as to the diagnostic pathway and as to the therapeutic options. Similarly, lymphatic system is involved in a wide spectrum of pathophysiologic processes of most chronic degenerative diseases. Translational medicine integrates the interdisciplinary scientific knowledge to improve diagnostic and therapeutic options in the biomedical field. Inflammation and lymphatic function are regarded as the connecting biochemical factors in most diseases. This review focuses on the scientific publications regarding lymphatic system in connection to psycho-neuroendocrine immunology, hormesis, epigenetics and more generally nutrition and lifestyle. The interaction between lymphology and translational medicine may play a relevant role to improve management of lymphedema on the one hand, and of chronic degenerative diseases on the other.

Psychological and Psychopathological Aspects of Kidney Transplantation: A Systematic Review

Kidney transplantation is a serious event that involves profound psychological, relational and social changes both for the patient and his family context. Assessment of personality profile, awareness of disease, family and social support of the patient candidate for kidney transplantation are necessary because factors not adequately considered, can influence the success of the transplant and alter the psychological stability of the patient. The present study aims to provide a systematic review of the literature of the last twelve years (2006-2018), focusing in particular on patient's readiness level and illness management and on possible psychopathology. Sixty-two studies were examined. Based on the Downs and Black checklist, most studies (n = 32) were of high quality; 15 of which related to lifestyle, health education, and therapeutic adherence in post-renal transplantation, 17 studies concerned the possible existence of psychopathology and cognitive impairment of renal deceased transplanted subjects. The literature used has shown that the population of kidney transplant patients is exposed to a high risk of psychiatric disorders with repercussions on the quality of life and the risk of rejection. Therefore, an adequate pre-transplant psychosocial assessment is necessary, which allows a more in-depth knowledge of the candidate to plan coping strategies and possible post-transplant psychotherapy.

Effectiveness of rehabilitation interventions to improve paretic propulsion in individuals with stroke - A systematic review

BACKGROUND

Stroke survivors often show reduced walking velocity and gait asymmetry. These gait abnormalities are associated with reduced propulsion of the paretic leg. This review aimed to provide an overview of the potential effectiveness of post-stroke rehabilitation interventions to improve paretic propulsion, ankle kinetics and walking velocity.

METHODS

A systematic search was performed in Pubmed, Web of Science, Embase, and Pedro. Studies were eligible if they reported changes in propulsion measures (impulse, peak value and symmetry ratios) or ankle kinetics (moment and power) following intervention in stroke survivors (group size ≥10). Study selection, data extraction and quality assessment were performed independently by two authors.

FINDINGS

A total of 28 studies were included, of which 25 studies applied exercise interventions, two studies focused on surgical interventions, and one on non-invasive brain stimulation. The number of high-quality trials was limited (N = 6; score Downs and Black scale ≥19). Propulsion measures were the primary outcome in eight studies. In general, mixed results were reported with 14 interventions yielding improvements in propulsion and ankle kinetics. In contrast, gains in walking velocity were observed in the vast majority of studies (N = 20 out of 23).

INTERPRETATION

Interventions that yielded gains in propulsion appeared to have in common that they challenged and/or enabled the utilization of latent propulsive capacity of the paretic leg during walking. Walking speed generally increased, regardless of the observed change in propulsion, suggesting the use of compensatory mechanisms. Findings should, however, be interpreted with some caution, as the evidence base for this emerging focus of rehabilitation is limited.

The effect and safety of exercise therapy in patients with systemic sclerosis: a systematic review

Given the shortcomings of previous literature reviews evaluating the effect and safety of exercise therapy in SSc, we aimed to carry out a systematic review of the literature specifically on this topic. A structured search strategy was performed in Medline (via PubMed) and other electronic databases from 1990 to 3 September 2019. Randomized controlled trials, observational designs, conference abstracts and trial registrations were included if they concerned SSc patients ≥18 years of age, exercise therapy and reported outcomes related to physical functioning. Nine articles were included. Four randomized controlled trials compared (a) hand exercises, (b) orofacial exercises, (c) aerobic exercises or (d) aerobic exercises plus resistance training with no exercise, demonstrating effects on hand function (a), maximum mouth opening (b), peak oxygen uptake (c + d) and quality of life. All five observational studies concerning hand, orofacial, aerobic and/or strengthening exercises reported improvements of hand function, mouth opening, aerobic capacity and/or muscle strength. In conclusion, the evidence on the effect and safety of exercise therapy in SSc is scanty.

Current and future perspectives on management of systemic sclerosis-associated interstitial lung disease

Introduction: Systemic sclerosis (SSc) is a rare and complex connective tissue disease characterized by fibrosis of the skin and internal organs. Interstitial lung disease (ILD) is a common complication of SSc and the leading cause of SSc-related death. No drugs are licensed for the treatment of SSc-ILD. Areas covered: This review provides an overview of the current treatment of SSc-ILD and a perspective on investigational therapies, focusing on those studied in randomized controlled trials. Expert opinion: There is substantial room for improvement in the treatment of SSc-ILD. Current treatment focuses on immunosuppressant therapies, particularly cyclophosphamide and mycophenolate. Hematopoietic stem cell transplantation has been shown to improve long-term outcomes, but the risk of treatment-related mortality restricts its use to select patients at specialized centers. Modifying the course of disease to improve outcomes remains the goal for new therapies. Several drugs are under investigation as potential therapies for SSc-ILD, providing hope that the limited treatment armamentarium for SSc-ILD will be expanded and improved in the near future. Expert consensus is needed on how to screen for and monitor SSc-ILD and on when to initiate and escalate therapy.

Developing a rare disease chronic care model: Management of systemic sclerosis (MANOSS) study protocol

AIM

The aim of the management of systemic sclerosis (MANOSS) study described in this protocol is to develop a chronic care model, based on a contextual analysis and stakeholder involvement, for patients living with the rare disease systemic sclerosis (SSc) in Switzerland.

DESIGN

Applying an implementation science approach, this study starts with an explanatory sequential mixed method study for contextual analysis, followed by broad stakeholder involvement for model development and a Delphi study to reach consensus.

METHODS

First, a quantitative cross-sectional survey with patients and healthcare professionals (HPs) will be conducted to identify current practice patterns of chronic illness management and technology readiness. Second, qualitative interviews with patients, family members and HPs will be performed to gain a deeper understanding of care needs identified in the quantitative survey. Third, a model of care will be co-created with input from patients, HPs and other experts. The eHealth enhanced Chronic Care Model will serve as a guiding framework. The new model and corresponding outcome parameters will be refined using a Delphi-study approach to reach consensus on a testable model of care for persons living with SSc. The protocol has received research ethics committee approval in September 2018 by the Swiss Ethics Committee.

DISCUSSION

The MANOSS study's participatory approach is essential for contextual fit of the model for patients with SSc in this setting. Subsequent feasibility testing and implementation are planned to evaluate the model's value in relation to health disparities faced by this patient population.

IMPACT

Patients living with this rare disease lack access to coordinated, specialized care and self-management support from qualified HPs. Reengineering of current care, with consideration for technological opportunities, is warranted to meet patients' and families' needs.

Occupational Therapy Treatment to Improve Upper Extremity Function in Individuals with Early Systemic Sclerosis: A Pilot Study

OBJECTIVE

To determine the feasibility and preliminary effects of occupational therapy to improve upper extremity function in patients with early systemic sclerosis (SSc; scleroderma) who have upper extremity contractures.

METHODS

A single-group pilot clinical rehabilitation trial was conducted at the University of Michigan Scleroderma Center. Patients with SSc and ≥1 upper extremity contracture (n = 21) participated in a total of 8 weekly in-person occupational therapy sessions. The therapy consisted of thermal modalities, tissue mobilization, and upper extremity mobility exercises. The participants were instructed to perform upper extremity exercises at home between sessions. Feasibility was measured by the percent enrollment as well as session attendance and session duration. The primary outcome measure was the Shortened Disabilities of the Arm, Shoulder and Hand measure (QuickDASH); secondary and exploratory outcomes included the Patient-Reported Outcomes Measurement Information System (PROMIS) physical function measures; objective measures of upper extremity mobility, strength, and coordination; and skin thickening. Linear mixed models were used to determine the effects of treatment on the primary and secondary outcomes.

RESULTS

Fifty percent of potentially eligible subjects (24 of 48) were interested in participating. Twenty-one (88%) of the 24 subjects were enrolled, and 19 (91%) of these 21 subjects completed all sessions. The mean ± SD age of the participants was 47.9 ± 16.1 years; 100% had diffuse SSc, and the mean disease duration was 3.1 years. At 8 weeks, participants had statistically significant improvement in the QuickDASH and PROMIS physical function measure (P = 0.0012 and P = 0.004, respectively). Approximately one-half of participants in the sample achieved improvement in the QuickDASH and PROMIS measure that exceeded minimally important differences.

CONCLUSION

In-person treatment sessions were feasible in the patients with SSc and resulted in statistically significant and clinically meaningful improvements in upper extremity and physical function. In future studies, the effects of SSc should be compared with those in a control condition, and the durability of treatment effects should be examined.

What is the role of smartphones on physical activity promotion? A systematic review and meta-analysis

OBJECTIVES

To identify and evaluate the effect of interventions that used cell phones as a means to promote physical activity (PA).

METHODS

The databases searched were MedLine/PubMed, Scopus, SPORTDiscus, PsycINFO, Science Direct, Lilacs, and SciELO. After removing duplicates, applying exclusion criteria, and checking the reference lists, 45 studies were reviewed. The Downs and Black (D&B) scale measured methodological quality, and a random effect model was used to compute the meta-analysis of PA by the reported unit (minutes per day or steps per day), delivery agent (application (APP), SMS, or other), and PA measurement (questionnaire, accelerometer, pedometer).

RESULTS

Mobile phone-based PA interventions were efficient in increasing both minutes [10.49; CI (3.37-17.60); p = 0.004] and steps per day [735.17; CI (227.72-1242.61); p = 0.005] in adults when compared to baseline. Furthermore, APP-based interventions were able to increase the number of steps (p = 0.04) and minutes per day of PA (p = 0.04) in adults. Also, 85% of included manuscripts were classified as moderate- to high-quality articles.

CONCLUSIONS

Mobile phone-based PA interventions, inclusive those delivery by APP, were effective to increase minutes and steps per day in adults.

Measuring and managing appearance anxiety in patients with systemic sclerosis

INTRODUCTION

Systemic sclerosis (SSc, scleroderma) is a progressive, autoimmune, connective tissue disease of unknown etiology that can cause changes in appearance in socially important areas of the body (e.g. face and hands). Social concerns related to changes in appearance can contribute to anxiety specific to situations where one's appearance will be evaluated, or appearance anxiety. Appearance anxiety is a relevant but underexplored construct in SSc. Areas covered: We review the current knowledge on appearance anxiety in SSc, including assessment of the construct and interventions. Relevant references in the field were obtained through a literature search in MEDLINE/PubMed and PsycINFO for articles published through September 2018. Expert commentary: There is a dearth of research in the SSc literature examining the construct of appearance anxiety. A growing interest in appearance anxiety in SSc has led to several relevant measures being validated in this population, including the Social Appearance Anxiety Scale. Important areas for future research are the development of interventions to address appearance anxiety and the use of randomized controlled trials to evaluate these interventions.

Interstitial lung disease associated with systemic sclerosis (SSc-ILD)

Background

Systemic sclerosis (SSc) is a rare connective tissue disease with a heterogeneous clinical course. Interstitial lung disease (ILD) is a common manifestation of SSc and a leading cause of death.

Main body

All patients newly diagnosed with SSc should receive a comprehensive clinical evaluation, including assessment of respiratory symptoms, a high-resolution computed tomography (HRCT) scan of the chest, and pulmonary function tests. ILD can develop in any patient with SSc, including those with pulmonary hypertension, but the risk is increased in those with diffuse (rather than limited) cutaneous SSc, those with anti-Scl-70/anti-topoisomerase I antibody, and in the absence of anti-centromere antibody. While it can occur at any time, the risk of developing ILD is greatest early in the course of SSc, so patients should be monitored closely in the first few years after diagnosis. An increased extent of lung fibrosis on HRCT and a low forced vital capacity (FVC) are predictors of early mortality. While not all patients will require treatment, current approaches to the treatment of progressive SSc-ILD focus on immunosuppressant therapies, including cyclophosphamide and mycophenolate mofetil. In patients with severe and/or rapidly progressive disease, both haematopoietic stem cell transplantation (HSCT) and lung transplantation have been successfully used. A number of medications, including the two drugs approved for the treatment of idiopathic pulmonary fibrosis (IPF), are under active investigation as potential new therapies for SSc-ILD.

Conclusions

Physicians managing patients with SSc should maintain a high level of suspicion and regularly monitor for ILD, particularly in the first few years after diagnosis.

What moves the rheumatologist? Unravelling decision making in the referral of systemic sclerosis patients to health professionals: a qualitative study

OBJECTIVES

Well-coordinated multidisciplinary non-pharmacological care is considered to be a cornerstone in the management of patients with systemic sclerosis. However, it has been discovered that unmet information and health care needs are common in patients with SSc. In addition, referrals by rheumatologists do not always correspond with potential treatment goals as identified by health professionals. The aim of this study was to gain insight into the current referral routine of rheumatologists in SSc patients and to identify and explore factors influencing rheumatologists' decisions about referral of SSc patients to health professionals.

METHODS

Qualitative semi-structured interviews were held with 13 rheumatologists specializing in SSc management from different hospitals in The Netherlands.

RESULTS

Our study identified rheumatologists' beliefs and local policy as influencing factors for referral to health professionals and a clear need for a better referral policy. Furthermore, a lack of knowledge about and low confidence in the competence of other disciplines were identified as barriers for referral to health professionals, which may possibly lead to undertreatment.

CONCLUSION

In the opinion of the majority of rheumatologists, adequate referral to health professionals requires an active role for the patient and increased visibility from health professionals.

Manual lymphatic drainage and quality of life in patients with lymphoedema and mixed oedema: a systematic review of randomised controlled trials

Purpose

To assess the impact of manual lymphatic drainage (MLD) on the health-related quality of life (HRQoL) of adults with lymphoedema or mixed oedema, through a systematic review of randomised controlled trials (RCTs).

Methods

MEDLINE, EMBASE, PsycINFO, CENTRAL, the Cochrane Database of Systematic Reviews and ClinicalTrials.gov were searched to identify RCTs evaluating HRQoL after a MLD intervention compared to non-MLD interventions (PROSPERO 2016:CRD42016042255). We extracted the effect of the interventions on the HRQoL (primary outcome) as well as data on volume and functional changes, and adverse events when available (secondary outcomes).

Results

Eight studies were eligible. The studies were heterogeneous in the aetiology of oedema, schemes of MLD applied, additional treatments offered with MLD, length of follow-up, instruments used to assess HRQoL and interventions offered to the control group. Five studies included patients with breast cancer-related arm lymphoedema; one study reported increased HRQoL among patients randomised to the MLD group. The two RCTs that involved patients with leg mixed oedema due to chronic venous insufficiency did not find between-group differences in the overall HRQoL. One trial included patients with hand oedema from systemic sclerosis and showed higher HRQoL in the group that received MLD. No studies reported reductions in HRQoL, or severe adverse events after MLD. The small numbers of patients analysed in all studies may have resulted in lack of power to detect between-group differences in HRQoL.

Conclusions

The effect of MLD on the HRQoL of patients with chronic oedema is unclear.

Orofacial consequences of systemic sclerosis: A systematic review

Orofacial involvement is common and often understated in the treatment clinical guidelines of systemic sclerosis. It impairs daily life by having repercussions on comfort, nutrition, aesthetics and self-confidence. This review aimed at describing exhaustively the different orofacial consequences of systemic sclerosis. A systematic search was conducted using four databases (PubMed, Cochrane Library, Dentistry & Oral Sciences Source and SCOPUS) up to December 2016 according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses. Grey literature and hand search were also included. To be eligible for the inclusion, studies needed to meet the following criteria: randomised controlled trials, cross-sectional studies, case-control studies, pilot studies or cohort studies and full text available in English or French, with abstract. The studies had to concern at least 30 patients suffering from systemic sclerosis and having clinical and radiological oropharyngeal examination. The diagnosis of systemic sclerosis had to be determined according to precise recommendations; the retrieved oropharyngeal manifestations had to affect hard or soft tissues of the mouth and/or pharynx and needed to be evaluated with clinical measures. Study selection, risk bias assessment (Newcastle-Ottawa scale) and data extraction were performed by two independent reviewers. The retrieved features were microstomia and xerostomia associated with real hyposialia, temporomandibular joint symptoms, high caries experience, periodontal diseases as well as an increased risk of oral cavity and pharynx cancer. Early diagnosis enabling early management, prevention and oral hygiene is the key to avoid complicated and invasive procedures. Studies with higher level of evidence remain necessary to create standardised protocols.

Scleroderma skin ulcers definition, classification and treatment strategies our experience and review of the literature

BACKGROUND

Skin ulcers (SU) are one of the most frequent manifestations of systemic sclerosis (SSc). SSc-SU are very painful, often persistent and recurrent; they may lead to marked impairment of patient's activities and quality of life. Despite their severe impact on the whole SSc patient's management, the proposed definition, classification criteria, and therapeutic strategies of SSc-SU are still controversial.

OBJECTIVE

The present study aimed to elaborate a comprehensive proposal of definition, classification, and therapeutic strategy of SSc-SU on the basis of our long-term single center experience along with a careful revision of the world literature on the same topic.

METHODS

A series of 282 SSc patients (254 females and 28 males; 84% with limited and 16% diffuse cutaneous SSc; mean age of 51.5±13.9SD at SSc onset; mean follow-up 5.8±4.6SDyears) enrolled during the last decade at our Rheumatology Unit were retrospectively evaluated with specific attention to SSc-SU. The SSc-SU were classified in 5 subtypes according to prominent pathogenetic mechanism(s) and localization, namely 1. digital ulcers (DU) of the hands or feet, 2. SU on bony prominence, 3. SU on calcinosis, 4. SU of lower limbs, and 5. DU presenting with gangrene. This latter is a very harmful evolution of both DU of the hands and feet needing a differential diagnosis with critical limb ischemia.

RESULTS

During the follow up period, one or more episodes of SSc-SU were recorded in over half patients (156/282, 55%); skin lesions were often recurrent and difficult-to-heal because of local complications, mainly infections (67.3%), in some cases associated to osteomyelitis (19.2%), gangrene (16%), and/or amputation (11.5%). SSc-SU were significantly associated with lower patients' mean age at the disease onset (p=0.024), male gender (p=0.03), diffuse cutaneous subset (p=0.015), calcinosis (p=0.002), telangiectasia (p=0.008), melanodermia (p<0.001), abnormal PAPs (p=0.036), and/or altered inflammation reactant (CRP, p=0.001). Therapeutic strategy of SSc-SU included both systemic and local pharmacological treatments with particular attention to complicating infections and chronic/procedural pain, as well as a number of non-pharmacological measures. Integrated local treatments were often decisive for the SSc-SU healing; they were mainly based on the wound bed preparation principles that are summarized in the acronym TIME (necrotic Tissue, Infection/Inflammation, Moisture balance, and Epithelization). The updated review of the literature focusing on this challenging issue was analyzed in comparison with our experience.

CONCLUSIONS

The recent advancement of knowledge and management strategies of SSc-SU achieved during the last years lead to the clear-cut improvement of patients' quality of life and reduced long-term disability.

Aerobic and resistance exercise in systemic sclerosis: State of the art

INTRODUCTION

Patients with systemic sclerosis (SSc) experience reduced exercise capacity and muscle strength compared with healthy subjects. There are also indications of reduced levels of physical activity.

OBJECTIVE

To present the current knowledge of physical exercise in SSc.

RESULTS

Most studies presently available [three case studies, one single subject experimental design, one study comparing patients with healthy controls, one quasi experimental design (pre-post), two clinical trials and two random controlled trials] have included small samples of patients, mostly composed of patients with and without pulmonary involvement. It seems that patients with SSc without pulmonary involvement are able to perform and benefit from aerobic exercises of at least moderate intensity. Exercise tolerance, aerobic capacity, walking distance, muscle strength and muscle function as well as health-related quality of life (HRQL) have been found to be improved after participation in programmes including aerobic exercise and aerobic exercise combined with resistance exercises. Improvements seem to be only partially retained at follow up. Patients with pulmonary involvement may also experience improved muscle strength, physical and aerobic capacity, as well as HRQL following exercise.

CONCLUSIONS

Patients with SSc without pulmonary involvement can be recommended to be as physically active as the general population. Patients with mild pulmonary involvement can be recommended to be physically active by engaging in exercises of moderate intensity and to participate in moderate-load resistance exercises. Health professionals should inform patients with SSc about the importance of physical activity and avoidance of a sedentary lifestyle.

Long-term improvement in activities of daily living in women with systemic sclerosis attending occupational therapy

Introduction

Systemic sclerosis often affects hand function, leading to severe disability in many subjects. There is little data available on the effects of occupational therapy in systemic sclerosis in current literature. The aim of our study was therefore to evaluate the effects of a cycle of occupational therapy on performing activities of daily living in a group of women with systemic sclerosis.

Method

Twenty women with systemic sclerosis were included in the study: 10 followed a cycle of occupational therapy; 10 were enrolled as controls. An occupational therapy cycle consisted of six meetings of 90 minutes each over a 3-week period. All women were evaluated by the Health Assessment Questionnaire and Evaluation of Daily Activity Questionnaire at baseline and after 24 weeks. The use of devices and alternative strategies was also assessed.

Results

We observed a significant reduction in the Health Assessment Questionnaire and Evaluation of Daily Activity Questionnaire scores in occupational therapy subjects after 6 months compared to controls. There was also evidence of significant improvement in four dimensions of the Evaluation of Daily Activity Questionnaire: eating; indoor mobility; outdoor mobility; and communication. The number of devices in the occupational therapy group increased significantly.

Conclusion

Our findings suggest a relevant role for occupational therapy in improving activities of daily living in women with systemic sclerosis. The use of strategies learned during occupational therapy sessions allows for long-lasting beneficial effects.

Systemic sclerosis: Association between physical function, handgrip strength and pulmonary function

BACKGROUND

Systemic sclerosis (SSc) is a multisystem disease affecting the skin, respiratory system and skeletal muscles. In SSc patients, hand function disability is the major factor limiting daily activities.

AIM

To evaluate the association of physical function with handgrip strength and pulmonary function in SSc patients. A further aim was to assess the relationship between handgrip strength and pulmonary function in patients with SSc.

METHOD

A cross-sectional study in which 28 patients with SSc underwent isometric handgrip strength (IHGS) measurement and pulmonary function tests and completed the Health Assessment Questionnaire Disability Index (HAQ-DI) to measure physical function.

RESULTS

The HAQ-DI scores were associated with the IHGS (r_s = -0.599, P = 0.001) and pulmonary function parameters, particularly the diffusion capacity for carbon monoxide (DLco; r_s = -0.642, P = 0.0004).

CONCLUSION

In patients with SSc, the degree of physical disability is associated with both hand grip strength and pulmonary function. However, there is no relationship between handgrip strength and pulmonary function in these patients.

Stretching Reduces Skin Thickness and Improves Subcutaneous Tissue Mobility in a Murine Model of Systemic Sclerosis

Objective

Although physical therapy can help preserve mobility in patients with systemic sclerosis (SSc), stretching has not been used systematically as a treatment to prevent or reverse the disease process. We previously showed in rodent models that stretching promotes the resolution of connective tissue inflammation and reduces new collagen formation after injury. Here, we tested the hypothesis that stretching would impact scleroderma development using a mouse sclerodermatous graft-versus-host disease (sclGvHD) model.

Methods

The model consists in the adoptive transfer (allogeneic) of splenocytes from B10.D2 mice (graft) into Rag2^−/− BALB/c hosts (sclGvHD), resulting in skin inflammation followed by fibrosis over 4 weeks. SclGvHD mice and controls were randomized to stretching in vivo for 10 min daily versus no stretching.

Results

Weekly ultrasound measurements of skin thickness and subcutaneous tissue mobility in the back (relative tissue displacement during passive trunk motion) successfully captured the different phases of the sclGvHD model. Stretching reduced skin thickness and increased subcutaneous tissue mobility compared to no stretching at week 3. Stretching also reduced the expression of CCL2 and ADAM8 in the skin at week 4, which are two genes known to be upregulated in both murine sclGvHD and the inflammatory subset of human SSc. However, there was no evidence that stretching attenuated inflammation at week 2.

Conclusion

Daily stretching for 10 min can improve skin thickness and mobility in the absence of any other treatment in the sclGvHD murine model. These pre-clinical results suggest that a systematic investigation of stretching as a therapeutic modality is warranted in patients with SSc.

Musculoskeletal Involvement in Systemic Sclerosis: An Unexplored Aspect of the Disease

Musculoskeletal (MSK) symptoms in patients with systemic sclerosis (SSc) include articular involvement (arthralgia, synovitis, contractures), which is often an early phenomenon and significantly contributes to the disability. Predominantly the hands are affected. Consensus in outcome measures of articular involvement is missing. Health Assessment Questionnaire Disability Index (HAQ-DI), Cochin Hand Function Scale (CHFS), Hand Mobility Index in Scleroderma (HAMIS), and Disease Activity Score of 28 Joints (DAS28) may be used for the assessment of different aspects of joint involvement. There is an unmet need for therapies confirmed by randomized controlled clinical trials (RCTs) to treat both synovitis and non-inflammatory joint involvement. The few rehabilitation studies that have been conducted have shown some promising efficacy.

Muscle involvement may be an early symptom. The presence of clinically meaningful muscle involvement often heralds an unfavourable prognosis. The histology of muscle biopsy shows a variable picture including inflammation and necrosis. Besides, signs of acute neurogenic atrophy have been recently described as a previously underestimated contributor to muscle weakness. Similar to articular involvement, the lack of classification criteria on inflammatory and non-inflammatory SSc-associated myopathies, and the lack of validated core set of outcome measures makes it difficult to perform RCTs.

The SSc-specific fibrinous tenosynovitis (tendon-friction rubs /TFRs/) is a frequent finding in SSc. Patients with TFR are at increased risk of developing renal, vascular, cardiac and gastrointestinal involvement and have reduced survival rates. Changes of fibrinous tenosynovitis can be objectively detected by ultrasound and may be used as an outcome measure in the treatment of MSK involvement.

Therapeutic and diagnostic outcomes of a standardised, comprehensive care pathway for patients with systemic sclerosis

Objectives

To determine the outcomes, including number of medical interventions and initiation of immunosuppressive treatment of a standardised, comprehensive, diagnostic care pathway for patients with systemic sclerosis (SSc). Patient characteristics associated with need for medical interventions and with need for immunosuppressive treatment were determined.

Methods

Data were routinely gathered in connection with a 2-day care pathway combining multidisciplinary care and complete diagnostic work-up of organ involvement in SSc. The number of patients in whom the pathway resulted in medical interventions, and/or initiation of immunosuppressives was recorded. Patient characteristics and diagnostic tests results were compared between patients with and without medical interventions, and patients with and without initiation of immunosuppressives by means of multivariable logistic regression analyses.

Results

During a period of 44 months, 226 patients with SSc were referred to the care pathway. They included 186 (82%) women with mean age of 54 (SD 14.5) years, and median disease duration of 4 years (range 1–11); 73 (32%) of them had diffuse cutaneous SSc. Medical interventions were initiated in 191 (85%) patients, including initiation of immunosuppressive treatment in n=49 (22%). Presence of telangiectasias and higher erythrocyte sedimentation rate were associated with any medical intervention. Of commonly available variables, lower age, higher skin score and absence of anticentromere antibody were associated with initiation of immunosuppressives.

Conclusions

A standardised comprehensive 2-day care pathway for patients with SSc resulted in additional diagnostic or therapeutic interventions in 85% of the patients, regardless of SSc subtype and disease duration. In 22% of the patients, immunosuppressive treatment was initiated.

The educational needs of people with systemic sclerosis: a cross-sectional study using the Dutch version of the Educational Needs Assessment Tool (D-ENAT)

The Dutch Educational Needs Assessment Tool (D-ENAT) systematically assesses educational needs of patients with rheumatic diseases. The present study aims to describe the educational needs of Dutch patients with systemic sclerosis (SSc). The D-ENAT was sent to 155 SSc patients registered at the outpatient clinic of a university hospital. The D-ENAT consists of 39 items in seven domains. “Each domain has different number of items therefore we normalized each domain score: (domain score/maximum) × 100) and expressed in percentage to enable comparisons between domains.” A total D-ENAT score (0–156) is calculated by summing all 39 items. In addition, age, disease duration, gender, educational level, present information need (yes/no) and information need (1–4; wanting to know nothing–everything) were recorded. Univariate regression analysis was used to examine factors associated with the D-ENAT scores. The response rate was 103 out of 155 (66 %). The mean % of educational needs scores (0–100 %; lowest–highest) were 49 % for “D-ENAT total score,” 46 % for “Managing pain,” 41 % for “Movement,” 43 % for “Feelings,” 59 % for “Disease process,” 44 % for “Treatments from health professionals,” 61 % for “Self-help measures” and 51 % for “Support systems.” No associations between the D-ENAT total score and age, disease duration, gender and educational level were found. The D-ENAT demonstrated its ability to identify educational needs of Dutch SSc patients. SSc patients demonstrated substantial educational needs, especially in the domains: “Disease process” and “Self-help measures.” The validity and practical applicability of the D-ENAT to make an inventory of SSc patients’ educational needs require further investigation.
