Behaviour change interventions for the management of Raynaud's phenomenon: a systematic literature review

Psychological factors in symptom severity and quality of life in Raynaud's phenomenon

BACKGROUND

Despite emotional stress being recognised as a key trigger for Raynaud's phenomenon episodes, research in the area is still in its infancy.

AIMS

This study investigated the role of psychological factors relating to symptom severity and quality of life, and differences between Raynaud's types (primary and secondary) to further inform the development of intervention in this field.

METHOD

A cross-sectional design was used. Two hundred and ten adults with Raynaud's completed an online questionnaire measuring stress, anxiety, depression, anxiety sensitivity, beliefs about emotions, symptom severity and quality of life.

RESULTS

Primary and secondary Raynaud's groups differed in anxiety (p < .004), symptom severity (p < .001) and quality of life (p < .001). Stepwise multiple regressions indicated anxiety and Raynaud's type explained 23% variance in hand symptom severity (p < .001); anxiety, Raynaud's type and anxiety sensitivity explained 29% variance in symptom severity (global impact, p < .001); depression, Raynaud's type and anxiety sensitivity explained 32% variance in quality of life (p < .001).

CONCLUSIONS

Results highlight the importance of psychological factors in Raynaud's phenomenon, indicating possible targets for treatment. Interventions such as cognitive behavioural therapy, which target both physical and psychological wellbeing, bear some promise as an adjuvant therapy for this group.

Efficacy analysis of minimally invasive surgery for Raynaud's syndrome

BACKGROUND

Raynaud's syndrome (RS), also referred to as Raynaud's phenomenon, is a vasospastic disorder causing episodic color changes in extremities upon exposure to cold or stress. These manifestations, either primary Raynaud's phenomenon (PRP) or associated with connective tissue diseases like systemic sclerosis (SSc) as secondary Raynaud's phenomenon (SRP), affect the quality of life. Current treatments range from calcium channel blockers to innovative surgical interventions, with evolving efficacy and safety profiles.

METHODS

In this retrospective study, patients diagnosed with RS were selected based on complete medical records, ensuring homogeneity between groups. Surgeries involved microscopic excision of sympathetic nerve fibers and stripping of the digital artery's adventitia. Postoperative care included antibiotics, analgesia, oral nifedipine, and heat therapies. Evaluation metrics such as the VAS pain score and RCS score were collected bi-weekly. Data analysis was conducted using SPSS 26.0, with significance set at p < 0.05.

RESULTS

In total, 15 patients formed the experimental group, with five presenting fingertip soft tissue necrosis and ten showing RS symptoms. Comparative analysis of demographic data between experimental and control groups, both containing 15 participants, demonstrated no significant age and gender difference. However, the "Mean Duration of RP attack" in the experimental group was notably shorter (9.47 min ± 0.31) than the control group (19.33 min ± 1.79). The RS Severity Score also indicated milder severity for the experimental cohort (score: 8.55) compared to the control (score: 11.23). Postoperative assessments at 2, 4, and 6 weeks revealed improved VAS pain scores, RCS scores, and other measures for the experimental group, showing significant differences (p < 0.05). One distinctive case showcased a variation in the common digital nerve and artery course in an RS patient.

CONCLUSION

Our retrospective analysis on RS patients indicates that microsurgical techniques are safe and effective in the short term. As surgical practices lean towards minimally invasive methods, our data supports this shift. However, extensive, prospective studies are essential for conclusive insights.

Raynaud Phenomenon and Other Vasospastic Disorders

Vasospastic disorders are prevalent in the general population and can affect individuals of any age. Primary (or idiopathic) vasospastic disorders often have a benign course; treatment focuses on the control of symptoms. Secondary vasospastic disorders occur owing to an underlying condition and have an increased risk of complications, including tissue loss and digital ulcerations; treatment should focus on the underlying condition. In this review, we discuss the pathophysiology, clinical presentation, diagnosis, and management of vasospastic disorders, including Raynaud syndrome, acrocyanosis, livedo reticularis, and pernio.

Factors influencing patient decision-making concerning treatment escalation in Raynaud's phenomenon secondary to systemic sclerosis

OBJECTIVE

To explore patient priorities and ranking of factors influencing patient decision-making concerning treatment escalation in the management of Raynaud's phenomenon (RP) secondary to systemic sclerosis (SSc).

METHODS

SSc patients were invited to participate in an online survey disseminated through patient-led organisations and social media platforms.

RESULTS

Responses from 747 people with self-reported SSc-RP were evaluable with broad international representation. The mean age (54.7years, SD 12.1), clinical phenotype and disease subsets distribution (limited [402/747, 53.8%], diffuse [260/747, 34.8%] and overlap disease, 85/747 [11.4%]) were consistent with expected demographics. Around half (56.3%) of patients reported their SSc-RP symptoms were adequately controlled. The 5 highest-ranked (out of 13) factors that would prompt treatment escalation for SSc-RP were; 1) inability to use the fingers properly 2) emergence of new digital ulcer (DU) on one or more fingers, 3) worsening pain or discomfort of Raynaud's, 4) more severe attacks, and 5) if it may help with internal problems. Despite symptoms not being adequately controlled, 47.1% were concerned about potential treatment side effects and were more likely to accept 'mild' (~20-40%) vs. 'severe' (2%) side effects. Patients were open to different management strategies for uncontrolled Raynaud's that included adding new treatment in combination to existing (52.8%), drug substitution (40.9%), increasing the current dose (28.8%), or focussing on non-pharmacological approaches (29.7%).

CONCLUSION

We have identified the relative importance of different factors influencing patient-preferences for treatment decision-making for SSc-RP. Side-effects profiles influence acceptability of drug treatments and many patients report a preference for non-pharmacological management of SSc-RP.

Richter J. Raynaud's Phenomenon: A Vascular Acrosyndrome That Requires Long-Term Care

BACKGROUND

Some 5-10% of the German population are affected by Raynaud's phenomenon (RP). In around 10-20% of cases RP arises from an underlying disease, most commonly a connective tissue disease. This review encompasses the diagnosis and differential diagnosis of RP and examines the efficacy of the currently available pharmaceutical and non-pharmaceutical treatment options.

METHODS

We conducted a selective literature search in PubMed using the search terms "Raynaud's phenomenon", "Raynaud's syndrome," "vasospasm," "vascular acrosyndrome," and "systemic sclerosis," together with a search of the Cochrane Database of Systematic Reviews up to April 2020.

RESULTS

Raynaud's phenomenon mainly affects the fingers or toes and is typically triggered by cold or emotional stressors. The most important diagnostic steps are demonstration of a tendency towards digital vasospasm, exclusion of occlusions in the afferent arteries and acral vessels, nail-fold capillaroscopy, and determination of autoantibody status. Tumor screening should be arranged in the presence of B symptoms or first manifestation of RP in old age. The onset of RP in childhood is a rare occurrence and points to a secondary origin. The principal options for treatment are protection against cold and administration of calcium antagonists, which reduces the occurrence of RP by around 20-40 %. The treatment of RP in patients with systemic sclerosis is described in the recommendations of the European League Against Rheumatism (EULAR).

CONCLUSION

At onset or after years of latency, patients with Raynaud phenomenon may have an underlying disease (most commonly a connective tissue disease). Long-term specialist care is necessary for asymptomatic patients with risk factors and for those with clinically manifest symptoms of an underlying condition alike.

Raynaud's phenomenon-an update on diagnosis, classification and management

Raynaud's phenomenon (RP) is used to describe a symptom complex caused by digital vascular compromise. RP is a clinical diagnosis. The typically episodic nature of RP has resulted in a reliance upon patient self-report for diagnosis. The term 'primary RP' is generally applied when no underlying pathology can be demonstrated. Whilst 'primary RP' is currently considered a distinct disorder, there is evidence that the term may comprise several entities that include a functional vasospastic disorder, a physiologically appropriate thermoregulatory response, subclinical atherosclerosis and 'cold intolerance'. Optimal management may differ depending on cause. The term 'secondary RP' encompasses a broad range of rheumatological, haematological, endocrinological and vascular pathology. RP can range from relatively benign but intrusive vasospasm, to the progressive obliterative microangiopathy of systemic sclerosis (SSc), in which severe digital ischaemia can threaten tissue viability. SSc has formed the focus of much of the research into RP but, consistent with most medical symptom complexes, the aetiopathogenesis of RP varies greatly dependent on cause. Vasospasm within the digital macro- and microvasculature occurs in SSc, but digital ischaemia is further compounded by a progressive obliterative microangiopathy. Recent work exploring the patient experience of SSc-RP is challenging the 'episodic' paradigm of 'Raynaud's', with important implications for clinical trials utilising diary-based patient-reported outcome instruments for assessing Raynaud's symptoms. This review shall examine the causes, pathogenesis, clinical features, classification and management of RP. A practical approach to the evaluation and management of RP is outlined, highlighting important knowledge gaps and unmet research needs where applicable. Key Points • Raynaud's phenomenon is a symptom complex related to digital vascular compromise secondary to broad-ranging pathology. • Raynaud's phenomenon, as currently classified, likely encompasses a number of aetiopathogenic processes. • Raynaud's phenomenon causes significant disease-related morbidity in autoimmune rheumatic diseases such as systemic sclerosis.
