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

EULAR recommendations for the non-pharmacological management of systemic lupus erythematosus and systemic sclerosis

OBJECTIVE

To develop evidence-based recommendations for the non-pharmacological management of systemic lupus erythematosus (SLE) and systemic sclerosis (SSc).

METHODS

A task force comprising 7 rheumatologists, 15 other healthcare professionals and 3 patients was established. Following a systematic literature review performed to inform the recommendations, statements were formulated, discussed during online meetings and graded based on risk of bias assessment, level of evidence (LoE) and strength of recommendation (SoR; scale A-D, A comprising consistent LoE 1 studies, D comprising LoE 4 or inconsistent studies), following the European Alliance of Associations for Rheumatology standard operating procedure. Level of agreement (LoA; scale 0-10, 0 denoting complete disagreement, 10 denoting complete agreement) was determined for each statement through online voting.

RESULTS

Four overarching principles and 12 recommendations were developed. These concerned common and disease-specific aspects of non-pharmacological management. SoR ranged from A to D. The mean LoA with the overarching principles and recommendations ranged from 8.4 to 9.7. Briefly, non-pharmacological management of SLE and SSc should be tailored, person-centred and participatory. It is not intended to preclude but rather complement pharmacotherapy. Patients should be offered education and support for physical exercise, smoking cessation and avoidance of cold exposure. Photoprotection and psychosocial interventions are important for SLE patients, while mouth and hand exercises are important in SSc.

CONCLUSIONS

The recommendations will guide healthcare professionals and patients towards a holistic and personalised management of SLE and SSc. Research and educational agendas were developed to address needs towards a higher evidence level, enhancement of clinician-patient communication and improved outcomes.

Increased Confidence and Deeper Understanding of Fatigue Following Participation in Fatigue Education and Management Education in Systemic Sclerosis: A Mixed Methods Evaluation of a Virtual Intervention

OBJECTIVE

No fatigue-specific programs exist for people with systemic sclerosis (SSc) despite the burden of fatigue and negative impact on daily activities. This study used a convergent parallel mixed methods design to evaluate the impact of an adapted virtual intervention, Fatigue and Activity Management Education in Systemic Sclerosis (FAME-iSS), in the United States.

METHODS

Eighteen people with SSc participated in three separate six-week FAME-iSS programs. Participants completed the modified Fatigue Impact Scale (m-FIS), the Self-Efficacy for Performing Energy Conservation Strategies Assessment (SEPESCA), the Patient-Reported Outcomes Measurement Information System (PROMIS) Self-Efficacy for Managing Symptoms, and the Hospital Anxiety and Depression Scale (HADS) before, immediately after, and three months post intervention. Data were analyzed using descriptive and nonparametric inferential statistics. Participants' perceptions of the program and their use of fatigue management strategies were qualitatively analyzed using content analysis.

RESULTS

Eighty-nine percent of participants were women with a mean ± SD age of 52.0 ± 11.6 years and a mean ± SD disease duration of 13.7 ± 14.5 years, and more than 70% had a college degree. Significant improvements were observed for self-efficacy on the PROMIS Self-Efficacy for Managing Symptoms (P = 0.002) and SEPESCA (P = 0.016) immediately post intervention, which continued to significantly improve up to the three-month follow-up (P = 0.006 and 0.035, respectively). Significant improvements were also observed for the m-FIS between baseline and the three-month follow-up (P = 0.029). Participants reported a deeper understanding of fatigue and that they liked sharing strategies and experiences with each other along with the facilitator, citing that "there was a power in our group because we had a common condition."

CONCLUSION

FAME-iSS resulted in improvements in the impact of fatigue and self-efficacy for managing symptoms and performing energy conservation strategies. Feedback was positive, and the virtual format allowed for greater accessibility and sharing of strategies.

Recommendations for physical activity and exercise in persons living with Systemic Lupus Erythematosus (SLE): consensus by an international task force

OBJECTIVE

This international task force aimed to provide healthcare professionals and persons living with systemic lupus erythematosus (SLE) with consensus-based recommendations for physical activity and exercise in SLE.

METHODS

Based on evidence from a systematic literature review and expert opinion, 3 overarching principles and 15 recommendations were agreed on by Delphi consensus.

RESULTS

The overarching principles highlight the importance of shared decision-making and the need to explain the benefits of physical activity to persons living with SLE and other healthcare providers. The 15 specific recommendations state that physical activity is generally recommended for all people with SLE, but in some instances, a medical evaluation may be needed to rule out contraindications. Pertaining to outdoor activity, photoprotection is necessary. Both aerobic and resistance training programmes are recommended, with a gradual increase in frequency and intensity, which should be adapted for each individual, and ideally supervised by qualified professionals.

CONCLUSION

In summary, the consensus reached by the international task force provides a valuable framework for the integration of physical activity and exercise into the management of SLE, offering a tailored evidence-based and eminence-based approach to enhance the well-being of individuals living with this challenging autoimmune condition.

Systemic pharmacological treatment of digital ulcers in systemic sclerosis: a systematic literature review

OBJECTIVE

To evaluate the evidence concerning systemic pharmacological treatments for SSc digital ulcers (DUs) to inform the development of evidence-based treatment guidelines.

METHODS

A systematic literature review of seven databases was performed to identify all original research studies of adult patients with SSc DUs. Randomized controlled trials (RCTs) and prospective longitudinal observational studies (OBSs) were eligible for inclusion. Data were extracted, applying the patient, intervention, comparison, outcome framework, and risk of bias (RoB) was assessed. Due to study heterogeneity, narrative summaries were used to present data.

RESULTS

Forty-seven studies that evaluated the treatment efficacy or safety of pharmacological therapies were identified among 4250 references. Data from 18 RCTs of 1927 patients and 29 OBSs of 661 patients, at various RoB (total 2588 patients) showed that i.v. iloprost, phosphodiesterase-5 inhibitors and atorvastatin are effective for the treatment of active DUs. Bosentan reduced the rate of future DUs in two RCTs (moderate RoB) and eight OBSs at low to high RoB. Two small studies (moderate RoB) indicate that Janus kinase inhibitors may be effective for the treatment of active DUs, otherwise there are no data to support the use of immunosuppression or anti-platelet agents in the management of DUs.

CONCLUSION

There are several systemic treatments, across four medication classes, that are effective therapies for the management of SSc DUs. However, a lack of robust data means it is not possible to define the optimal treatment regimen for SSc DUs. The relatively low quality of evidence available has highlighted further areas of research need.

Living with Systemic Sclerosis: A Patient and Physician Perspective

The fears associated with being diagnosed with a disease unfamiliar to many, systemic sclerosis, is described by a patient living with systemic sclerosis. The patient, a coauthor, also describes the challenges of being a young person diagnosed with a chronic and, at times, debilitating disease. Despite initially being told that she had 6 months to live, she has embraced life and has become a fierce advocate for others living with systemic sclerosis. The physician perspective is provided by two rheumatologists who specialize in systemic sclerosis and work at a scleroderma center of excellence. This section details the current challenges in diagnosing systemic sclerosis early and the dangers of a delayed diagnosis. It also reviews the importance of multi-disciplinary specialty centers in the care of patients with systemic sclerosis as well as empowering patients through education.

The effect of silver fibre gloves on Raynaud's phenomenon in patients with systemic sclerosis: a double-blind randomized crossover trial

OBJECTIVES

Silver fibre gloves transport heat from the palm to the fingers, possibly reducing the burden of RP in SSc patients. We aim to evaluate the clinical efficiency of this intervention.

METHODS

A multicentre, double-blind, randomized trial was performed, accounting for interindividual differences and external factors using a crossover design. Patients were randomized in two groups: group 1 wore 8% silver fibre gloves in period 1 and normal gloves in period 2 and group 2 vice versa. Each period lasted 6 weeks. The primary outcome was the Raynaud Condition Score (RCS) over time (minimal clinical important difference 1.4), assessed three times per week using an online questionnaire. Secondary outcomes included vascular complications and Scleroderma-Health Assessment Questionnaire (SHAQ). Outcomes were evaluated before unblinding using linear mixed models.

RESULTS

A total of 85 SSc patients were included, with 76 completing the study. The mean RCS during 2 weeks before the study (i.e. without gloves) was 6.4 (s.d. 1.6). Both with silver fibre gloves and normal gloves the mean RCS decreased to 3.9 (s.d. 2.3) with a similar course over time. There was no difference in mean RCS over time between the type of gloves [β = 0.067 (95% CI -0.006, 0.19)]. Of secondary outcomes, total SHAQ [β = 0.036 (95% CI 0.026, 0.046)] was slightly higher with silver fibre gloves, which is clinically irrelevant. Three patients developed new digital ulcers with normal gloves vs one patient with silver fibre gloves [odds ratio 3.2 (95% CI 0.32, 31.1)].

CONCLUSIONS

Wearing gloves in SSc patients clearly decreases the RP burden. Our results do not support the hypothesis that increased heat transport of 8% silver fibre gloves is associated with less disease burden as measured in this study by the RCS compared with normal gloves.

Advances in the Treatment of Systemic Sclerosis

Although systemic sclerosis (SSc) is currently incurable, there have been recent advances in treatment. This review article begins by providing a brief background to SSc in terms of disease subtyping and autoantibodies, because both predict disease trajectory and help clinicians to select appropriate monitoring and treatment protocols. Broad principles of management are then described: ‘disease-modifying’ therapies and therapies directed at reducing disease burden and/or progression of SSc-related digital vascular disease and of internal organ involvement. Next, advances in the management of digital vasculopathy, pulmonary arterial hypertension (PAH), interstitial lung disease (ILD) and early diffuse cutaneous SSc are discussed in turn, for example: (a) increased use of phosphodiesterase inhibitors and endothelin receptor antagonists for digital vasculopathy; (b) early recognition and treatment of PAH, including with combination therapies; (c) increased use of mycophenolate mofetil and of nintedanib in ILD; and (d) immunosuppression now as standard practice in early diffuse cutaneous SSc, and autologous haematopoietic stem cell transplantation for highly selected patients with progressive diffuse disease. Finally, future challenges are discussed, including ensuring that all patients with SSc are monitored and treated according to best practice guidelines, and whenever possible giving patients the opportunity to participate in clinical trials.
