Stress and resilience in rheumatic diseases: a review and glimpse into the future

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.

Systemic Sclerosis Patients Experiencing Mindfulness-Based Stress Reduction Program: The Beneficial Effect on Their Psychological Status and Quality of Life

Psychological concerns in Systemic Sclerosis (SSc) patients represent an important issue and should be addressed through non-pharmacological treatments. Thus, the aim of the present study was to assess the effects of the Mindfulness-Based Stress Reduction (MBSR) program on psychological variables and the perspectives and experiences of patients with an SSc diagnosis. Notably, 32 SSc patients were enrolled and assigned to either the intervention (MBSR) group or the waitlist group. Inclusion criteria were (i) age ≥ 18 years, SSc diagnosis according to EULAR/ACR diagnostic criteria and informed consent. Exclusion criteria were previous participation in any Mind-Body Therapy or psychiatric diagnosis. Quantitative and qualitative outcomes were investigated through clinometric questionnaires and individual interviews. MBSR did not significantly impact outcomes such as physical functionality, anxiety, hopelessness, depression, physical health status, perceived stress, mindfulness and mental health status. For the anger evaluation, statistically significant differences are found for both controlling and expressing anger, indicating that the MBSR program had a favorable impact. As for qualitative results, more awareness of daily activities, stress reduction in terms of recognizing the causes and implementing self-strategies to prevent them, adherence to therapy, and recognition of the effect of medication on their bodies were reported. In conclusion, it is important to highlight the absence of negative or side effects of the MBSR program and the positive impact on patients' experience and perspective; thus, we suggest this approach should be taken into account for SSc patients.

Age-related mechanisms in the context of rheumatic disease

Ageing is characterized by a progressive loss of cellular function that leads to a decline in tissue homeostasis, increased vulnerability and adverse health outcomes. Important advances in ageing research have now identified a set of nine candidate hallmarks that are generally considered to contribute to the ageing process and that together determine the ageing phenotype, which is the clinical manifestation of age-related dysfunction in chronic diseases. Although most rheumatic diseases are not yet considered to be age related, available evidence increasingly emphasizes the prevalence of ageing hallmarks in these chronic diseases. On the basis of the current evidence relating to the molecular and cellular ageing pathways involved in rheumatic diseases, we propose that these diseases share a number of features that are observed in ageing, and that they can therefore be considered to be diseases of premature or accelerated ageing. Although more data are needed to clarify whether accelerated ageing drives the development of rheumatic diseases or whether it results from the chronic inflammatory environment, central components of age-related pathways are currently being targeted in clinical trials and may provide a new avenue of therapeutic intervention for patients with rheumatic diseases.

Impact of resilience on disease severity and psychiatric comorbidities in patients with fibromyalgia

Background

Resilience is the process of adjusting successfully in the face of adversity, trauma, threats, or severe stress, such as serious health problems. It is one of the factors that affect recovery from psychiatric disorders. It was suggested that fibromyalgia patients have low resilience. This study aimed to assess the impact of resilience on disease severity and psychiatric comorbidities in patients with fibromyalgia.

Results

We found that patients with fibromyalgia had a significantly lower resilience and higher prevalence of psychiatric comorbidities than the control group (P < 0.05). Also, fibromyalgia patients with high disease severity had a significantly lower resilience and a higher percentage of psychiatric problems than those with a better disease state (P = 0.0001). Also, there was a significant negative correlation of resilience with disease severity (as assessed by the FIQ score), visual analog scale (VAS) of anxiety, and VAS of depression (P = 0.0001).

Conclusion

Resilience significantly impacts the severity and psychiatric comorbidities in patients with fibromyalgia. So, enhancing and improving resilience must be considered in the management protocols of fibromyalgia patients.

Acute stress induces an inflammation dominated by innate immunity represented by neutrophils in mice

It is well known that psychological stress could affect the immune system and then regulate the disease process. Previous studies mostly focused on the effects of chronic stress on diseases and immune cells. How acute stress affects the immune system remains poorly understood. In this study, after 6 hours of restraint stress or no stress, RNA was extracted from mouse peripheral blood followed by sequencing. Through bioinformatics analysis, we found that when compared with the control group, differentially expressed genes in the stress group mainly displayed up-regulated expression. Gene set enrichment analysis results showed that the enriched gene terms were mainly related to inflammatory response, defense response, wounding response, wound healing, complement activation and pro-inflammatory cytokine production. In terms of cell activation, differentiation and chemotaxis, the enriched gene terms were related to a variety of immune cells, among which neutrophils seemed more active in stress response. The results of gene set variation analysis showed that under acute stress, the inflammatory reaction dominated by innate immunity was forming. Additionally, the concentration of serum IL-1β and IL-6 increased significantly after acute stress, indicating that the body was in an inflammatory state. Importantly, we found that acute stress led to a significant increase in the number of neutrophils in peripheral blood, while the number of T cells and B cells decreased significantly through flow cytometric analysis. Through protein-protein interaction network analysis, we screened 10 hub genes, which mainly related to inflammation and neutrophils. We also found acute stress led to an up-regulation of Ccr1, Ccr2, Xcr1 and Cxcr2 genes, which were involved in cell migration and chemotaxis. Our data suggested that immune cells were ready to infiltrate into tissues in emergency through blood vessels under acute stress. This hypothesis was supported in LPS-induced acute inflammatory models. After 48 hours of LPS treatment, flow cytometric analysis showed that the lungs of mice with acute stress were characterized by increased neutrophil infiltration, decreased T cell and B cell infiltration. Immunohistochemical analysis also showed that acute stress led to more severe lung inflammation. If mice received repeat acute stress and LPS stimulation, the survival rate was significantly lower than that of mice only stimulated by LPS. Altogether, acute stress led to rapid mobilization of the immune system, and the body presented an inflammatory state dominated by innate immune response represented by neutrophils.

Combining transplant professional's psychosocial donor evaluation and donor self-report measures to optimise the prediction of HRQoL after kidney donation: an observational prospective multicentre study

OBJECTIVES

Living donor kidney transplantation is currently the preferred treatment for patients with end-stage renal disease. The psychosocial evaluation of kidney donor candidates relies mostly on the clinical viewpoint of transplant professionals because evidence-based guidelines for psychosocial donor eligibility are currently lacking. However, the accuracy of these clinical risk judgements and the potential added value of a systematic self-reported screening procedure are as yet unknown. The current study examined the effectiveness of the psychosocial evaluation by transplant professionals and the potential value of donor self-report measures in optimising the donor evaluation. Based on the stress-vulnerability model, the predictive value of predonation, intradonation and postdonation factors to impaired longer term health-related quality of life (HRQoL) of kidney donors was studied.

DESIGN

An observational prospective multicentre study.

SETTING

Seven Dutch transplantation centres.

PARTICIPANTS

588 potential donors participated, of whom 361 donated. Complete prospective data of 230 donors were available. Also, 1048 risk estimation questionnaires were completed by healthcare professionals.

METHODS

Transplant professionals (nephrologists, coordinating nurses, social workers and psychologists) filled in risk estimation questionnaires on kidney donor candidates. Furthermore, 230 kidney donors completed questionnaires (eg, on HRQoL) before and 6 and 12 months after donation.

PRIMARY AND SECONDARY OUTCOME MEASURES

HRQoL, demographic and preoperative, intraoperative and postoperative health characteristics, perceived support, donor cognitions, recipient functioning and professionals risk estimation questionnaires.

RESULTS

On top of other predictors, such as the transplant professionals' risk assessments, donor self-report measures significantly predicted impaired longer term HRQoL after donation, particularly by poorer predonation physical (17%-28% explained variance) and psychological functioning (23%).

CONCLUSIONS

The current study endorses the effectiveness of the psychosocial donor evaluation by professionals and the additional value of donor self-report measures in optimising the psychosocial evaluation. Consequently, systematic screening of donors based on the most prominent risk factors provide ground for tailored interventions for donors at risk.

Resilience: A Protective Factor from Depression and Anxiety in Mexican Dialysis Patients

Depression and anxiety are highly prevalent psychological disorders in end-stage renal disease (ESRD) that have a negative clinical impact. The purpose of our study was to identify factors associated with the presence of depression and anxiety, in a sample of ESRD patients treated with hemodialysis. We included 187 patients from two dialysis facilities, age 18-65 years. Beck's depression and anxiety inventories, KDQOL36 questionnaire, the cognitive distortion scale and the Mexican scale of resilience were used. Socio-demographic and clinical information was obtained from medical records. Depression was present in 143 (76.4%) patients. Patient with depression were older (33 (26-52) years vs. 30 (24.43) years, p = 0.025), had a lower education level (36% vs. 9%, p = 0.001), used more medications (67% vs. 36%, p = 0.001), had a comorbidity (75% vs. 41%, p = 0.001), and a higher proportion were waiting for a kidney transplant. Anxiety was present in 112 (59.8%) cases. By multivariate analysis, depression was independently associated with lower education, absence of previous kidney transplant, anxiety, higher cognitive distortion, lower psychological resilience, and lower quality of life scores. In conclusion, lower psychological resilience, lower education level, and higher cognitive distortions are factors associated with depression and anxiety in ESRD patients.

Experiences of self-care during the COVID-19 pandemic among individuals with rheumatoid arthritis: A qualitative study

Objectives

This study aimed to explore the impact of the coronavirus disease 2019 (COVID‐19) pandemic on self‐care of individuals living with rheumatoid arthritis (RA).

Methods

Guided by a constructivist, qualitative design, we conducted one‐to‐one in‐depth telephone interviews between March and October 2020 with participants with RA purposively sampled for maximum variation in age, sex and education, who were participating in one of two ongoing randomized‐controlled trials. An inductive, reflexive thematic analysis approach was used.

Results

Twenty‐six participants (aged 27–73 years; 23 females) in British Columbia, Canada were interviewed. We identified three themes: (1) Adapting to maintain self‐care describes how participants took measures to continue self‐care activities while preventing virus transmissions. While spending more time at home, some participants reported improved self‐care. (2) Managing emotions describes resilience‐building strategies such as keeping perspective, positive reframing and avoiding negative thoughts. Participants described both letting go and maintaining a sense of control to accommodate difficulties and emotional responses. (3) Changing communication with health professionals outlined positive experiences of remote consultations with health professionals, particularly if good relationships had been established prepandemic.

Conclusion

The insights gained may inform clinicians and researchers on ways to support the self‐care strategies of individuals with RA and other chronic illnesses during and after the COVID‐19 pandemic. The findings reveal opportunities to further examine remote consultations to optimize patient engagement and care.

Patient or Public Contribution

This project is jointly designed and conducted with patient partners in British Columbia, Canada. Patient partners across the United Kingdom also played in a key role in providing interpretations of themes during data analysis.

Guided internet-based cognitive-behavioral therapy for patients with rheumatic conditions: A systematic review

CONTEXT

Rheumatic conditions have a large impact on both patients and society. Many patients experience adjustment problems, such as symptoms of anxiety and depression and sleep problems, contributing to high healthcare costs. Internet-based cognitive-behavioral therapy (iCBT) has shown to support patients with somatic conditions in coping with their disease, with therapist-guided iCBT usually showing larger effects than unguided iCBT. However, the specific relevance of guided iCBT for rheumatic conditions has not been reviewed yet, which could have important implications for implementation.

OBJECTIVES

The objective of our review was to give an overview of evaluations of guided iCBT for rheumatic conditions, including physical, psychological, and impact on daily life outcomes.

METHODS

This review is registered with PROSPERO with registration number CRD42020154911. The review followed PRISMA guidelines and included an assessment of risk of bias. PubMed, PsycINFO, Embase, Cochrane Library, Web of Science, and Emcare were searched until 5 October 2020. Inclusion criteria were: patients ≥18 years old with a rheumatic condition, randomized controlled trial, accessible full-text English article, original data, inclusion of psychological, and/or physical and/or impact outcomes, and therapist-guided iCBT. Study and sample characteristics, as well as clinical variables were extracted.

RESULTS

A systematic search identified 6089 studies, of which 8 trials were included, comprising of 1707 participants in total. Significant medium to large between-group effects were found for psychological outcomes (depression, anxiety, catastrophizing, self-efficacy) and impact on daily life outcomes (impact on daily life, quality of life), whilst results for physical outcomes (pain intensity, fatigue) were mixed.

CONCLUSION

Whilst more research is warranted, for instance regarding physical outcomes, cost-effectiveness, safety of the intervention, and moderators of iCBT success, our results show that guided iCBT could be an important addition to medical treatment for rheumatic conditions. Guided iCBT can improve psychological and impact on daily life outcomes in patients with rheumatic conditions, which is promising for iCBT implementation in clinical practice.

Mental health and quality of life for people with rheumatoid arthritis or ankylosing spondylitis in Aotearoa New Zealand following the COVID-19 national lockdown

The aim of this study was to investigate the effects of lockdown on the mental health (anxiety and depression) and quality of life (QOL) of people with rheumatoid arthritis (RA) and ankylosing spondylitis (AS) in the context of the COVID-19 pandemic and public health measures instituted at a national level by the New Zealand Government. The present cohort was 104 individuals with RA (73.1%) and AS (26.9%) who had previously completed surveys for the Patient Opinion Real-Time Anonymous Liaison (PORTAL) project in 2018. Participants completed an online survey between July and September 2020 assessing their experiences over the first national COVID-19 lockdown in New Zealand (March–May, 2020). Fear of SARS-CoV-2 infection, baseline anxiety, and being younger in age were all predictors of participants’ current anxiety levels. Current QOL scores were significantly lower than prior to lockdown and were predicted by baseline QOL and current depression. No variables predicted current depression other than baseline levels. The COVID-19 pandemic appears to have had an impact on QOL and anxiety levels, but not depression for people with RA and AS in New Zealand. These novel findings imply that appropriate screening of mental health issues should be included in planning within the ongoing COVID-19 pandemic and for future pandemics to optimise the wellbeing of people with RA and AS.

Effect of childhood trauma on disease severity in patients with fibromyalgia: The mediating role of psychological resilience

Objectives

This study aims to investigate the effect of childhood traumas on the disease severity in fibromyalgia and evaluate the mediating role of psychological resilience in this effect.

Patients and methods

Between June 2017 and January 2018, this study included a total of 80 female patients (mean age: 31.9±4.0 years; range, 20 to 40 years) with fibromyalgia according to the 2010 American College of Rheumatology fibromyalgia diagnostic criteria. All patients were evaluated using the sociodemographic data form, Resilience Scale for Adults (RSA), Childhood Trauma Questionnaire (CTQ), and Fibromyalgia Impact Questionnaire (FIQ).

Results

A positive correlation was observed between the FIQ and CTQ total scores, emotional abuse, physical abuse, and physical neglect scores. The FIQ was negatively correlated with the RSA scores. Path analysis conducted to evaluate mediating effect of psychological resilience revealed that psychological resilience had a mediator role in the correlation between FIQ and emotional abuse, physical abuse, and physical neglect scores.

Conclusion

The main finding of this study is the protective effect of psychological resilience -improvable capacity to cope with early life traumas- on fibromyalgia symptoms that leads to negative functioning of several aspects.

Management of Fatigue in Rheumatoid Arthritis

Fatigue in rheumatoid arthritis is highly prevalent. It is correlated only weakly with disease activity but more so with pain, mood, personality features, poor sleep, obesity and comorbidities. Fatigue can be measured by many standardised questionnaires and more easily with a Visual Analogue Scale or numeric rating scale. Most patients with RA have some fatigue, and at least one in six have severe fatigue. Chronic pain and depressed mood are also common in RA patients with significant fatigue. It affects function and quality of life and is worse on average in women. Evidence-based treatment for fatigue includes treatment of underlying disease activity (with on average modest improvement of fatigue), exercise programmes and supervised self-management programmes with cognitive-behavioural therapy, mindfulness and reinforcement (such as reminders). The specific programmes for exercise and behavioural interventions are not standardised. Some medications cause fatigue such as methotrexate. More research is needed to understand fatigue and how to treat this common complex symptom in RA that can be the worst symptom for some patients.

Mental health consequences of infections by coronaviruses including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)

BACKGROUND

Anxiety and stress like mental illnesses are the common outcomes of viral epidemics and pandemics. Novel coronavirus disease 2019 (COVID-19) outbreak caused by the severe acute respiratory syndrome coronavirus virus 2 (SARS-CoV-2) was first reported in Wuhan, China, and then spread all over the world in a short time.

OBJECTIVES

To highlight and discuss the impact of COVID-19 pandemic on mental or psychological health.

METHOD

Literature search and collection of the information were performed using PubMed, the reports from the World health organization, and the Center for disease control and prevention.

RESULTS

COVID-19 infection has already been declared as a global pandemic, which in association with infodemic has increased the risk of psychiatric/psychological disorders. A large population of the world is prone to develop anxiety, depressive disorders, and other mental abnormalities. Therefore, timely psychological interventions and preventive strategies are required. Moreover, the infection has been reported to be linked with cerebrovascular conditions; therefore, patients with underlying cerebrovascular diseases should be given attention.

CONCLUSION

COVID-19-mediated mental health complications and cerebrovascular conditions may cause a huge burden on healthcare communities in the future. Therefore, timely intervention and the development or application of preventive strategies are required to decrease the risk of neurological consequences.

Psychosocial and clinical effects of the COVID-19 pandemic in patients with childhood rheumatic diseases and their parents

This study aimed to evaluate the psychological symptoms of children and adolescents with rheumatological diseases (RD) and their parents during the outbreak. A web-based questionnaire survey was conducted in a cross-sectional design in RD patients and healthy controls. The Hospital Anxiety and Depression Scale was used to evaluate parental psychiatric status; while the State-Trait Anxiety Inventory for Child was used for children. Four hundred and fifty-nine patients with RD and their parents completed the present study, as well as 336 healthy peers. The age and gender of the children were similar across groups. Under 12 years of age, the trait anxiety of the children and the psychological symptoms of parents were similar across groups; while over 13 years of age, anxiety and depression scores of the parents, as well as trait anxiety of the children were higher than the control groups’ (7.3 ± 3.4 vs 6.3 ± 3.8, p = 0.006 for parental anxiety; 6.6 ± 3.8 vs. 5.3 ± 3.9, p < 0.001 for parental depression; 36.1 ± 8.7 vs. 33.3 ± 7.9, p = 0.002 for child trait anxiety). In patient group, there were no differences in scale scores according to variables such as rheumatological disease diagnosis, the consulting of doctor for treatment, thinking that RD increases the risk of COVID-19, the history of rheumatic disease attack during the pandemic process, and the use of biological agents. The children’s trait anxiety was positively correlated with their parents’ anxiety (r = 0.414, p < 0.001) and depression (r = 0.300, p < 0.001) scores. These findings suggest that clinicians should pay attention to the psychiatric symptoms of both children with RD and their parents during the pandemic.

Psychological contributors to the frail phenotype: The association between resilience and frailty in patients with cirrhosis

We examined whether a key psychological trait-resilience, defined as one's ability to recover quickly from difficulties-contributes to the frail phenotype in patients with cirrhosis. Included were 300 adult patients with cirrhosis who underwent outpatient physical frailty testing using the Liver Frailty Index and resilience testing using the Connor-Davidson Resilience Scale (CD-RISC). The Liver Frailty Index was categorized as robust, prefrail-robust, prefrail-frail, and frail; CD-RISC was categorized using population norms as: least, less, more, and most resilient. Linear regression was used to assess factors associated with frailty (by the Liver Frailty Index per 0.1 unit change). Among the most resilient, only 10% were frail; among the least resilient, 29% were frail. In univariable analysis, resilience was strongly associated with the Liver Frailty Index (coef = -0.13 per point increase; 95% confidence interval [CI], -0.20 to -0.60; P < .001) and remained significantly associated with frailty in multivariable adjustment (coef = -0.13, 95% CI -0.19 to -0.07; P < .001). Low resilience is strongly associated with the frail phenotype in patients with cirrhosis. Given that resilience is modifiable, our data suggest that effective interventions to mitigate frailty should include strategies to build resilience in patients with low baseline resilience.

Development of Resilience Among Rheumatoid Arthritis Patients: A Qualitative Study

OBJECTIVE

Resilience, the ability to recover from and adapt successfully to stressful situations, is a valuable resource for patients who live with chronic conditions. This qualitative study examines the development of resilience among rheumatoid arthritis (RA) patients. We aimed to describe the resilience development process and to describe strategies used by patients to cultivate resilience.

METHODS

Our approach combined ethnographic data collection and narrative analysis methods. Semistructured interviews were conducted with adult RA patients in the US. Interviewees were asked to discuss their experiences with diagnosis, living with RA, coping with challenges, treatment, and health care providers. The interviews were audiorecorded, transcribed, and analyzed to describe the stages of resilience development and to identify patients' strategies for building/maintaining resilience.

RESULTS

Eighteen patients were interviewed, ages 27-80 years and with RA duration of 5-41 years. Patient responses to challenging situations were grouped into 3 stages: 1) lacking capacity to handle the situation, 2) struggling but growing in capacity to handle the situation, and 3) attaining mastery. Patients used 10 strategies to cultivate resilience: perseverance, exchanging social support, pursuing valued activities, flexibility, positive reframing, acceptance, humor, avoiding threatening thoughts, equanimity, and maintaining a sense of control.

CONCLUSION

RA patients acquire resilience in a dynamic process of learning in response to new challenges. Patients use a combination of behavioral and emotion management strategies to cultivate resilience. Awareness of these strategies may benefit patients, health care providers, and researchers developing behavioral interventions and social support programs in the context of RA and other chronic diseases.

Living with arthritis: a "training camp" for coping with stressful events? A survey on resilience of arthritis patients following the COVID-19 pandemic

Resilience is defined as “the capacity of individuals to cope successfully with significant change or adversity”. The challenge posed by the COVID-19 pandemic may potentially represent an overwhelmingly stressful event for patients with chronic diseases. Aim of our study was to investigate the levels of resilience in individuals with inflammatory arthritis living in Emilia Romagna, the third hardest-hit Italian region during the ongoing COVID-19 pandemic. To this purpose, we developed a survey consisting of four different sections assessing demographic characteristics, the 14-item resilience scale (RS14) and questionnaires evaluating depression and anxiety. Consecutive patients with inflammatory arthritis were recruited over a short time frame immediately after the end of national lockdown and compared with control individuals from the general population. One hundred twenty-two patients and 173 controls were included. Levels of resilience, as measured by RS14 score, were significantly higher in patients with inflammatory arthritis (82.6 ± 14.0 vs 79.0 ± 12.8, p = 0.018). After stratification for gender, the difference in RS14 score was maintained in women (p = 0.045), but not in men (p = 0.252). High resilience, defined as having a RS14 score > 90, was significantly more prevalent in patients than in controls (30% vs 16%, p = 0.009). In arthritis patients, no significant differences in RS14 were observed after stratification for specific diagnosis, age, or disease duration and activity. Our findings suggest that patients with inflammatory arthritis may be more resilient than the general population towards unexpected stressful events such as the ongoing COVID-19 pandemic.

Key Points • Living with inflammatory arthritis may foster resilience. • After COVID-19, patients with inflammatory arthritis were more resilient than the general population.

Towards a Transversal Definition of Psychological Resilience: A Literature Review

Background and objectives: This paper addresses psychological resilience, a multidisciplinary theoretical construct with important practical implications for health sciences. Although many definitions have been proposed in several contexts, an essential understanding of the concept is still lacking up to now. This negatively affects comparisons among research results and makes objective measurement difficult. The aim of this review is to identify shared elements in defining the construct of resilience across the literature examined in order to move toward a conceptual unification of the term. Materials and methods: A literature review was performed using the electronic databases ‘PubMed’ and ‘PsycINFO’. Scientific studies written in English between 2002 and May 2019 were included according to the following key terms: ‘Psychological’, ‘resilience’, and ‘definition’. Results: The review identifies five macro-categories that summarize what has been reported in the recent literature concerning the resilience phenomenon. They serve as a preliminary and necessary step toward a conceptual clarification of the construct. Conclusions: We propose a definition of psychological resilience as the ability to maintain the persistence of one’s orientation towards existential purposes. It constitutes a transversal attitude that can be understood as the ability to overcome the difficulties experienced in the different areas of one’s life with perseverance, as well as good awareness of oneself and one’s own internal coherence by activating a personal growth project. The conceptual clarification proposed will contribute to improving the accuracy of research on this topic by suggesting future paths of investigation aimed at deeply exploring the issues surrounding the promotion of resilience resources.

A goal management intervention for patients with polyarthritis and elevated levels of depressive symptoms: a quasiexperimental study

Purpose: Goal was to establish whether an intervention that aims to increase goal management competencies is effective in decreasing elevated levels of depressive symptoms and increasing well-being in patients with polyarthritis.Materials and methods: Eighty-five persons with polyarthritis and elevated levels of depressive symptoms participated in the goal management intervention consisting of six group-based meetings. A quasiexperimental design with baseline measurement, follow-up at 6 months and a reference group of 151 patients from an observational study was applied. Primary outcome was depression; secondary outcomes were anxiety, purpose in life, positive affect, satisfaction with participation, goal management strategies, and arthritis self-efficacy. A linear mixed model procedure was applied to evaluate changes in outcomes.Results: No improvement was found for depressive symptoms and no changes were found for the secondary outcomes, except for positive affect that improved in the intervention group. This increase was mediated by an increase in goal adjustment. Furthermore, goal maintenance decreased and self-efficacy for other symptoms increased in the intervention group.Conclusion: This study indicates that interventions designed to aid patients with arthritis with goal management skills are potentially helpful for increasing positive affect, although further studies are needed.Implications for rehabilitationPeople with polyarthritis have to manage their disease in combination with possibly conflicting roles and personal goals, resulting in an ongoing process of finding equilibrium in a constantly changing situation.Based on a person-focused view, the program Right on Target focused on coping with threatened activities and life goals due to arthritis.The program consisted of six group-based meetings led by a trained nurse and a personal trajectory wherein participants were stimulated to try out various behavioral options related to an own threatened activity in concordance with their personal goals.The program seemed effective in increasing flexible goal adjustment and self-efficacy and participants experienced more positive affect directly after the program and at 6-month follow-up.

Tailored, Therapist-Guided Internet-Based Cognitive Behavioral Therapy Compared to Care as Usual for Patients With Rheumatoid Arthritis: Economic Evaluation of a Randomized Controlled Trial

Background

Internet-based cognitive behavioral therapy can aid patients with rheumatoid arthritis with elevated levels of distress to enhance their quality of life. However, implementation is currently lacking and there is little evidence available on the (cost-) effectiveness of different treatment strategies.

Objective

Cost-benefit ratios are necessary for informing stakeholders and motivating them to implement effective treatment strategies for improving health-related quality of life (HRQoL) of patients with rheumatoid arthritis. A cost-effectiveness study from a societal perspective was conducted alongside a randomized controlled trial on a tailored, therapist-guided internet-based cognitive behavioral therapy (ICBT) intervention for patients with rheumatoid arthritis with elevated levels of distress as an addition to care as usual (CAU).

Methods

Data were collected at baseline or preintervention, 6 months or postintervention, and every 3 months thereafter during the 1-year follow-up. Effects were measured in terms of quality-adjusted life years (QALYs) and costs from a societal perspective, including health care sector costs (health care use, medication, and intervention costs), patient travel costs for health care use, and costs associated with loss of labor.

Results

The intervention improved the quality of life compared with only CAU (Δ QALYs=0.059), but at a higher cost (Δ=€4211). However, this increased cost substantially reduced when medication costs were left out of the equation (Δ=€1863). Of all, 93% (930/1000) of the simulated incremental cost-effectiveness ratios were in the north-east quadrant, indicating a high probability that the intervention was effective in improving HRQoL, but at a greater monetary cost for society compared with only CAU.

Conclusions

A tailored and guided ICBT intervention as an addition to CAU for patients with rheumatoid arthritis with elevated levels of distress was effective in improving quality of life. Consequently, implementation of ICBT into standard health care for patients with rheumatoid arthritis is recommended. However, further studies on cost reductions in this population are warranted.

The role of stress in the mosaic of autoimmunity: An overlooked association

Stress is defined as the pscyophysiological reaction in which the steady state is disturbed or threatened. Stress is not always perceived as a negative response. Stress results when environmental demands exceed an individuals' adaptive capacities. Autoimmune diseases are heterogeneous group of chronic diseases which occur secondary to loss of self antigen tolerance. The etiopathogenesis of autoimmune disease is uncertain. Genetic factors as well as environmental factors appear to interplay, leading to a cascade of events resulting in disease onset. Stress has been postulated to play a role in disease onset in the genetically susceptible patients. During the stress response, catecholamines and glucocorticoids are released from locus coeruleus and adrenal gland. These biomolecules exert control over various immune cells in the innate and adaptive arms of the immune system, thereby altering the cytokine profile released. The increase of IL-4 promotes T-helper 2 (T_h2) cell differentiation, while the decrease in IL-12 and the increased IL-10 production reduce the number of T-helper 1 (T_h1) cells. The relationship between stress and autoimmune diseases is intricate. Stress has been shown to be associated with disease onset, and disease exacerbations in rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease, multiple sclerosis, Graves' disease as well as other autoimmune conditions. In certain conditions such as psoriasis, stress has been implicated in delaying lesion clearance upon the application of standard treatment regimes. Finally, psychological therapy and cognitive behavioral therapy aimed to reduce stress levels was shown to be effective in influencing better outcomes in many autoimmune diseases. The purpose of this paper is to closer inspect the clinical evidence regarding the role of stress on influencing the various aspects of disease entities.

Does psychological stress in patients with clinically suspect arthralgia associate with subclinical inflammation and progression to inflammatory arthritis?

Background

Within established rheumatoid arthritis (RA), stress can have pro-inflammatory effects by activating the immune system via the hypothalamic-pituitary-adrenal axis and the autonomic nervous system. It is unknown if stress levels also promote inflammation during RA development. We studied whether the psychological stress response was increased in clinically suspect arthralgia (CSA) and if this associated with inflammation at presentation with arthralgia and with progression to clinical arthritis.

Methods

In 241 CSA patients, psychological stress was measured by the Mental Health Inventory (MHI-5) and the Perceived Stress Scale (PSS-10) at first presentation and during follow-up. Systemic inflammation was measured by C-reactive protein (CRP) and joint inflammation by 1.5 T-MRI of wrist, MCP, and MTP joints.

Results

At baseline, 12% (24/197) of CSA patients had a high psychological stress response according to the MHI-5. This was not different for patients presenting with or without an elevated CRP, with or without subclinical MRI-detected inflammation and for patients who did or did not develop arthritis. Similar findings were obtained with the PSS-10. When developing clinical arthritis, the percentage of patients with ‘high psychological stress’ increased to 31% (p = 0.025); during the first year of treatment this decreased to 8% (p = 0.020). ‘High psychological stress’ in non-progressors remained infrequent over time (range 7–13%). Stress was associated with fatigue (p = 0.003) and wellbeing (p < 0.001).

Conclusions

Psychological stress was not increased in the phase of arthralgia, raised at the time of diagnoses and decreased thereafter. The lack of an association with inflammation in arthralgia and this temporal relationship, argue against psychological stress having a significant contribution to progression from CSA to inflammatory arthritis.

Resilience in women with autoimmune rheumatic diseases

OBJECTIVE

To evaluate the relationship between resilience and clinical outcomes in patients with autoimmune rheumatic diseases.

METHODS

Focus groups, individual interviews, and chart reviews were done to collect data on 188 women with autoimmune rheumatic diseases, namely rheumatoid arthritis (n=51), systemic lupus erythematosus (n=70), systemic sclerosis (n=35), and Sjögren's syndrome (n=32). Demographic, clinical, and laboratory variables were assessed including disease activity by patient reported outcomes. Resilience was evaluated by using the Brief Resilience Scale. Bivariate, multiple linear regression, and classification and regression trees were used to analyse data.

RESULTS

Resilience was influenced by age, duration of disease, and socioeconomic status. Lower resilience scores were observed in younger patients (<48years) with systemic lupus erythematosus, rheumatoid arthritis, and systemic sclerosis who had low socioeconomic status, whereas older patients (>50years) had higher resilience scores regardless of socioeconomic status. There was no influence of disease activity on resilience. A particular behaviour was observed in systemic sclerosis in which patients with high socioeconomic status and regular physical activity had higher resilience scores.

CONCLUSION

Resilience in patients with autoimmune rheumatic diseases is a continuum process influenced by age and socioeconomic status. The ways in which these variables along with exercise influence resilience deserve further investigation.

The Key Role of Pain Catastrophizing in the Disability of Patients with Acute Back Pain

PURPOSE

This study investigated the role of anxiety sensitivity, resilience, pain catastrophizing, depression, pain fear-avoidance beliefs, and pain intensity in patients with acute back pain-related disability.

METHOD

Two hundred and thirty-two patients with acute back pain completed questionnaires on anxiety sensitivity, resilience, pain catastrophizing, fear-avoidance beliefs, depression, pain intensity, and disability.

RESULTS

A structural equation modelling analysis revealed that anxiety sensitivity was associated with pain catastrophizing, and resilience was associated with lower levels of depression. Pain catastrophizing was positively associated with fear-avoidance beliefs and pain intensity. Depression was associated with fear-avoidance beliefs, but was not associated with pain intensity. Finally, catastrophizing, fear-avoidance beliefs, and pain intensity were positively and significantly associated with acute back pain-related disability.

CONCLUSION

Although fear-avoidance beliefs and pain intensity were associated with disability, the results showed that pain catastrophizing was a central variable in the pain experience and had significant direct associations with disability when pain was acute. Anxiety sensitivity appeared to be an important antecedent of catastrophizing, whereas the influence of resilience on the acute back pain experience was limited to its relationship with depression.

Stress and Disease Onset in Antineutrophil Cytoplasmic Antibody-Associated Vasculitis

OBJECTIVE

To explore the potential contribution of stress as a trigger for disease onset in patients with antineutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV).

METHODS

53 AAV and 85 rheumatoid arthritis (RA) patients as well as 53 healthy controls (HC) were thoroughly asked for the number and impact of stressful life events, coping strategies, and available social support 12 months prior to disease onset. Anxiety, depression, personality dimensions, insomnia, and fatigue were also determined.

RESULTS

AAV patients reported higher scoring of the impact of stressful life events compared to the RA and HC group prior to disease onset (2.8 ± 3.1 vs 1.8 ± 2.1 vs 1.7 ± 2.3, p-values: 0.047 and 0.053, respectively). While the number of reported stressful events was found to be significantly higher in AAV vs RA patients but not HC, certain coping strategies and social support features were more commonly implemented by AAV patients compared to HC, but not RA patients. As far as personality and other psychosocial characteristics, AAV patients displayed significantly higher psychoticism traits compared to RA, with no other differences being detected between AAV patients and both RA and HC. After adjusting for potential cofounders, scoring of the impact of stressful life events >3 was independently associated with AAV development compared to both RA and HC [ORs (95% CI): 4.6 (1.6-13.4) and 4.4 (1.0-19.0), respectively].

CONCLUSION

The perceived impact of stressful life events prior to disease onset emerged as a contributing factor for AAV development.

The role of psychological factors in inflammatory rheumatic diseases: From burden to tailored treatment

Inflammatory rheumatic diseases have a long-lasting effect on patients' physical and psychological functioning, for instance, due to disabling symptoms and unpredictable disease course. Consequently, many patients show adjustment problems such as depressed mood, which in turn can negatively influence their disease outcome. Specific biopsychosocial factors have shown to affect this outcome. For example, daily stress, cognitive-behavioral risk factors such as pain catastrophizing and avoidance, and resilience factors such as optimism and social support influence the quality of life, physical symptoms of pain and fatigue, and inflammatory markers. Psychological interventions tackling these factors can have beneficial effects on physical and psychological functioning. Recent advances in screening for patients at risk, tailored treatment, and eHealth further broaden the efficiency and scope of these interventions while simultaneously optimizing patient empowerment. This chapter describes the biopsychosocial risk and resilience factors related to disease outcome and the possible benefits of psychological treatment strategies in inflammatory rheumatic diseases.

Resilience and hope during advanced disease: a pilot study with metastatic colorectal cancer patients

Background

The balance between hope-hopelessness plays an important role in the way terminally ill patients report quality of life, and personal resilience may be related to hope at the end of life. The objective of this study was to explore associations between personal resilience, hope, and other possible predictors of hope in advanced cancer patients.

Methods

A cross-sectional pilot study was carried out with metastatic colorectal cancer patients in a tertiary hospital. The patients answered the Connor-Davidson Resilience Scale, Herth Hope Index, Barthel Index, an instrument addressing family and social support, visual-numeric scales for pain and suffering, a two-item screening for depression, socio-demographic and socio-economic information about the family.

Results

Forty-four patients were interviewed (mean age 56 years; range 29-86). A strong correlation was noted between resilience and hope (0.63; p < 0.05). No correlation was found between hope and independence for activities of daily living, support from family and community, and pain and suffering levels. Of the 44 patients, 20 presented with depressive symptoms. These depressive patients had lower resilience (p = 0.005) and hope (p = 0.003), and higher scores of suffering (p < 0.001). The association between resilience and hope kept stable after adjusting for age, gender, and presence of depression (p < 0.001).

Conclusion

Given that resilience is a dynamic, changeable path that can improve hope, resilience-fostering interventions should be most valued in palliative care settings and should be commenced as soon as possible with cancer patients. Patients with advanced stages of non-malignant conditions would also probably benefit from such interventions.

Affective disturbance in rheumatoid arthritis: psychological and disease-related pathways

In addition to recurrent pain, fatigue, and increased rates of physical disability, individuals with rheumatoid arthritis (RA) have an increased prevalence of some mental health disorders, particularly those involving affective or mood disturbances. This narrative Review provides an overview of mental health comorbidities in RA, and discusses how these comorbidities interact with disease processes, including dysregulation of inflammatory responses, prolonged difficulties with pain and fatigue, and the development of cognitive and behavioural responses that could exacerbate the physical and psychological difficulties associated with RA. This article describes how the social context of individuals with RA affects both their coping strategies and their psychological responses to the disease, and can also impair responses to treatment through disruption of patient-physician relationships and treatment adherence. Evidence from the literature on chronic pain suggests that the resulting alterations in neural pathways of reward processing could yield new insights into the connections between disease processes in RA and psychological distress. Finally, the role of psychological interventions in the effective and comprehensive treatment of RA is discussed.

A qualitative study of patients' perspectives on collaboration to support self-management in routine rheumatology consultations

BACKGROUND

Self-management of inflammatory arthritis (IA) requires patients to address the impact of symptoms, treatment, and the psychosocial consequences of a long term condition. There are several possible mechanisms for facilitating self-management, including patient-clinician interactions in routine consultations. This requires patients to collaborate in their healthcare, and clinicians to specifically encourage and help patients to do so. To design training that enables clinicians to support patients to be actively involved and self-manage requires understanding both patients' and clinicians' perspectives about what is important and feasible. Previous research explored the perspectives of clinicians who had undertaken brief training which they were putting into practice in their routine consultations. This study explored the perspectives of patients attending those routine consultations to identify aspects of the interaction that influenced collaboration and self-management.

METHODS

Nineteen patients with IA who had attended a routine consultation with a rheumatology clinician at one of four hospitals in England took part in semi-structured interviews. Interviews were transcribed, anonymised and analysed using inductive thematic analysis.

RESULTS

Three themes encompass participants' thoughts about interactions that facilitated collaboration in consultations and their ability to self-manage their IA: first, patients and clinicians viewing care as a shared endeavour, including patients responding actively to their IA and clinicians exploring and negotiating with patients; second, the need for clinicians to understand the challenges faced by patients, appreciate the impact of IA and focus on patients' priorities; and third, clinicians using an open communication style, including the use of non-didactic, patient-centred approaches. A fourth theme was perceived benefits of actively engaging in consultations, including increased confidence to deal with the impact of IA and greater acceptance of a long term condition.

CONCLUSIONS

Patients perceive that self-management can be facilitated when clinicians and patients view healthcare as a shared responsibility, underpinned by clinicians as experts in the disease and patients as experts in living with it. Clinicians can support patients' self-management by using non-didactic communication skills to identify patients' priorities, and to prompt patients to problem-solve and share in setting the consultation agenda. This should inform skills-training for rheumatology clinicians.

Dispositional Affect in Unique Subgroups of Patients with Rheumatoid Arthritis

Background. Patients with rheumatoid arthritis may experience increased negative outcomes if they exhibit specific patterns of dispositional affect. Objective. To identify subgroups of patients with rheumatoid arthritis based on dispositional affect. The secondary objective was to compare mood, pain catastrophizing, fear of pain, disability, and quality of life between subgroups. Methods. Outpatients from a rheumatology clinic were categorized into subgroups by a cluster analysis based on dispositional affect. Differences in outcomes were compared between clusters through multivariate analysis of covariance. Results. 227 patients were divided into two subgroups. Cluster 1 (n = 85) included patients reporting significantly higher scores on all dispositional variables (experiential avoidance, anxiety sensitivity, worry, fear of pain, and perfectionism; all p < 0.001) compared to patients in Cluster 2 (n = 142). Patients in Cluster 1 also reported significantly greater mood impairment, pain anxiety sensitivity, and pain catastrophizing (all p < 0.001). Clusters did not differ on quality of life or disability. Conclusions. The present study identifies a subgroup of rheumatoid arthritis patients who score significantly higher on dispositional affect and report increased mood impairment, pain anxiety sensitivity, and pain catastrophizing. Considering dispositional affect within subgroups of patients with RA may help health professionals tailor interventions for the specific stressors that these patients experience.

Psychological Resilience, Affective Mechanisms, and Symptom Burden in a Tertiary Care Sample of Patients with Fibromyalgia

Research demonstrates that patients with fibromyalgia who have higher positive and lower negative affect have lower symptom burden. Affect has been shown to be associated with resilience. This study examined the relationship between affect, resilience and fibromyalgia symptom burden in a clinical sample of patients with fibromyalgia. We hypothesized that (a) positive and negative affect would be associated with fibromyalgia symptom burden; (b) resilience would be associated with positive and negative affect; (c) resilience would be associated with fibromyalgia symptom burden; and (d) the connection between resilience and fibromyalgia symptom burden would be mediated by both positive and negative affect. A sample of 858 patients with fibromyalgia completed questionnaires. Mediation modelling revealed statistically significant direct effects of resilience on fibromyalgia symptom burden (β = -0.10, P < 0.001) and statistically significant indirect effects of resilience on fibromyalgia symptom burden through affect (β = -0.36, P < 0.001), suggesting that both resilience and affect influence fibromyalgia symptom burden. Our results suggest that improving affect through resiliency training could be studied as a modality for improving fibromyalgia symptom burden.

Personality change associated with chronic diseases: pooled analysis of four prospective cohort studies

BACKGROUND

Common chronic conditions, such as heart disease and cancer, are associated with increased psychological distress, functional limitations and shortened life expectancy, but whether these diseases alter aspects of personality remains unclear.

METHOD

To examine whether the onset of heart disease, stroke, diabetes, cancer, hypertension, arthritis and respiratory disease is associated with subsequent changes in personality traits of the five-factor model, we pooled data from the Health and Retirement Study, the Midlife in the United States Survey, and the graduate and sibling samples of the Wisconsin Longitudinal Study for an individual-participant meta-analysis (total n=17,493; mean age at baseline 55.8 years).

RESULTS

After adjustment for age, we observed consistent decreases in extraversion [-0.25 T-scores per one disease; 95% confidence interval (CI) -0.40 to -0.10], emotional stability (-0.40, 95% CI -0.61 to -0.19), conscientiousness (-0.44, 95% CI -0.57 to -0.30) and openness to experience (-0.25, 95% CI -0.37 to -0.13) but not in agreeableness (-0.05, 95% CI -0.19 to 0.08) after the onset of chronic diseases. The onset of each additional chronic disease accelerated the average age-related personality change by 2.5 years in decreasing extraversion, 5.5 years in decreasing conscientiousness, and 1.6 years in decreasing openness to experience, and attenuated the increasing levels of emotional stability by 1.9 years. Co-morbid conditions were associated with larger changes than single diseases, suggesting a dose-response association between morbidity and personality change.

CONCLUSIONS

These results support the hypothesis that chronic diseases influence personality development in adulthood.

Change of psychological distress and physical disability in patients with rheumatoid arthritis over the last two decades

OBJECTIVE

During the past decades, a more cautious approach with respect to prescribing medication and physical exercise progressed toward evidence-based guidelines regarding the management of rheumatoid arthritis (RA). Currently, physical activity and other means to improve well-being and functioning are encouraged, and the disease is targeted earlier with more intensive and aggressive pharmacologic treatment. The current study examined whether psychological distress and physical disability in patients with RA reduced over the last 2 decades and whether this is explained by a reduction of disease activity.

METHODS

From 1990-2011, consecutive patients with RA (n = 1,151, age range 17-86 years, 68% female, 62% rheumatoid factor positive) were monitored at diagnosis and after 3-5 years of treatment (followup). Depressed mood, anxiety, and physical disability were predicted in multiple linear regression analyses by year of assessment, disease activity, and patient demographics.

RESULTS

Over the decades, depressed mood (P = 0.01), anxiety (P = 0.001), and physical disability (P = 0.02) reduced at diagnosis and within-treatment improvement of anxiety (P = 0.04) and physical disability (P < 0.001) increased. Percentages of patients with depressed mood, anxiety, and physical disability at followup changed from 25%, 23%, and 53%, respectively, 2 decades ago to 14%, 12%, and 31%, respectively, currently. After taking account of reduction in disease activity, the decrease in physical disability remained significant (P < 0.001).

CONCLUSION

Over the last 2 decades, psychological distress and physical disability decreased. This favorable trend might partly be due to reduced disease activity. The results indicate that patients with RA have a better opportunity to live a valued life currently than 20 years ago.

Rheumatology clinicians' experiences of brief training and implementation of skills to support patient self-management

BACKGROUND

Self-management of arthritis requires informed, activated patients to manage its physical and psychosocial consequences. Patient activation and self-management can be enhanced through the use of cognitive-behavioural approaches, which have a strong evidence base and provide insight into the variation in outcome of patients with ostensibly the same degree of disease activity. However, training for rheumatology health professionals in theory and skills underpinning the facilitation of self-management is not widely available. To develop such training, this study explored rheumatology clinicians' experiences of a variety of brief skills training courses to understand which aspects were helpful or unhelpful, and to identify the barriers and facilitators of applying the skills in clinical practice.

METHODS

16 clinicians who had previously attended communication and self-management skills training participated in semi-structured interviews: 3 physicians, 3 physiotherapists, 4 nurses, 6 occupational therapists. Transcripts were analysed (ED) using a hybrid inductive and deductive thematic approach, with a subset independently analysed (SH, RG-H, RJ).

RESULTS

3 overarching themes captured views about training undertaken and subsequent use of approaches to facilitate self-management. In 'putting theory into practice', clinicians felt that generic training was not as relevant as rheumatology-specific training. They wanted a balance between theory and skills practice, and identified the importance of access to ongoing support. In 'challenging professional identity', models of care and working cultures influenced learning and implementation. Training often challenged a tendency to problem-solve on behalf of patients and broadened clinicians' remit from a primary focus on physical symptoms to the mind and body interaction. In 'enhanced practice', clinicians viewed consultations as enhanced after training. Focus had shifted from clinicians' agendas to those of patients, and clinicians reported eliciting patients' priorities and the use of theoretically-driven strategies such as goal-setting.

CONCLUSIONS

To varying extents, clinicians were able to learn and implement new approaches to support patient self-management after brief training. They believed that cognitive behavioural and communication skills to facilitate self-management enhanced their practice. To optimise self-management support in routine care brief, skills-based, rheumatology-specific training needs to be developed, alongside ongoing clinical supervision. Further research should examine patients' perspectives of care based on these approaches.

Validity and reliability of the Spanish version of the 10-item CD-RISC in patients with fibromyalgia

Background

No resilience scale has been validated in Spanish patients with fibromyalgia. The aim of this study was to evaluate the validity and reliability of the 10-item CD-RISC in a sample of Spanish patients with fibromyalgia.

Methods

Design: Observational prospective multicenter study. Sample: Patients with diagnoses of fibromyalgia recruited from primary care settings (N = 208). Instruments: In addition to sociodemographic data, the following questionnaires were administered: Pain Visual Analogue Scale (PVAS), the 10-item Connor-Davidson Resilience scale (10-item CD-RISC), the Fibromyalgia Impact Questionnaire (FIQ), the Hospital Anxiety and Depression Scale (HADS), the Pain Catastrophizing Scale (PCS), the Chronic Pain Acceptance Questionnaire (CPAQ), and the Mindful Attention Awareness Scale (MAAS).

Results

Regarding construct validity, the factor solution in the Principal Component Analysis (PCA) was considered adequate, so the KMO test had a value of 0.91, and the Barlett’s test of sphericity was significant (χ2 = 852.8; gl = 45; p < 0.001). Only one factor showed an eigenvalue greater than 1, and it explained 50.4% of the variance. PCA and Confirmatory Factor Analysis (CFA) results did not show significant differences between groups. The 10-item CD-RISC scale demonstrated good internal consistency (Cronbach’s alpha = 0.88) and test-retest reliability (r = 0.89 for a six-week interval). The 10-item CD-RISC score was significantly correlated with all of the other psychometric instruments in the expected direction, except for the PVAS (−0.115; p = 0.113).

Conclusions

Our study confirms that the Spanish version of the 10-item CD-RISC shows, in patients with fibromyalgia, acceptable psychometric properties, with a high level of reliability and validity.

The association of sleep and pain: an update and a path forward

Ample evidence suggests that sleep and pain are related. However, many questions remain about the direction of causality in their association, as well as mechanisms that may account for their association. The prevailing view has generally been that they are reciprocally related. The present review critically examines the recent prospective and experimental literature (2005-present) in an attempt to update the field on emergent themes pertaining to the directionality and mechanisms of the association of sleep and pain. A key trend emerging from population-based longitudinal studies is that sleep impairments reliably predict new incidents and exacerbations of chronic pain. Microlongitudinal studies employing deep subjective and objective assessments of pain and sleep support the notion that sleep impairments are a stronger, more reliable predictor of pain than pain is of sleep impairments. Recent experimental studies suggest that sleep disturbance may impair key processes that contribute to the development and maintenance of chronic pain, including endogenous pain inhibition and joint pain. Several biopsychosocial targets for future mechanistic research on sleep and pain are discussed, including dopamine and opioid systems, positive and negative affect, and sociodemographic factors.

PERSPECTIVE

This critical review examines the recent prospective and experimental research (2005-present) on the association of sleep and pain in an attempt to identify trends suggestive of directionality and potential mechanisms. An update on this literature is needed to guide future clinical efforts to develop and augment treatments for chronic sleep disturbance and chronic pain.

Disposition and adjustment to chronic pain

Several empirical studies have shown that personal characteristics act as differential variables, which determine how pain is experienced and how the chronic pain patient adjusts to pain. The main aim of the present research is to review the relationships between some dispositional characteristics and pain adjustment. Taking into account the empirical literature, 6 personality traits that are relevant to the pain experience have been selected: neuroticism, anxiety sensitivity, and experiential avoidance as risk factors that increase the probability of patients experiencing a disability; and extraversion, optimism, and resilience as personal resources that increase their capacity to manage pain effectively. The results suggest that it would be useful to include an assessment of normal personality structure during the multi-dimensional evaluation of a person with chronic pain. Understanding these individual personality characteristics will aid in designing pain intervention programs and help predict possible treatment outcomes.

Role of neuroendocrine and neuroimmune mechanisms in chronic inflammatory rheumatic diseases--the 10-year update

BACKGROUND

Neuroendocrine immunology in musculoskeletal diseases is an emerging scientific field. It deals with the aspects of efferent neuronal and neurohormonal bearing on the peripheral immune and musculoskeletal systems. This review aims to add new information that appeared since 2001.

SEARCH STRATEGY

The following PubMed search sentence was used to find a total of 15,462 references between 2001 and March 2013: "(rheum* OR SLE OR vasculitis) AND (nerve OR hormone OR neurotransmitter OR neuropeptide OR steroid)." In a continuous process, year by year, this search strategy yielded relevant papers that were screened and collected in a database, which build the platform of this review.

RESULTS

The main findings are the anti-inflammatory role of androgens, the loss of androgens (androgen drain), the bimodal role of estrogens (support B cells and inhibit macrophages and T cells), increased conversion of androgens to estrogens in inflammation (androgen drain), disturbances of the gonadal axis, inadequate amount of HPA axis hormones relative to inflammation (disproportion principle), biologics partly improve neuroendocrine axes, anti-corticotropin-releasing hormone therapies improve inflammation (antalarmin), bimodal role of the sympathetic nervous system (proinflammatory early, anti-inflammatory late-most probably due to catecholamine-producing local cells), anti-inflammatory role of alpha melanocyte-stimulating hormone, vasoactive intestinal peptide, and the Vagus nerve via α7 nicotinergic receptors. Circadian rhythms of hypothalamic origin are responsible for circadian rhythms of symptoms (neuroimmune link revealed). Important new pain-sensitizing immunological pathways were found in the last decade.

CONCLUSIONS

The last decade brought much new information that gave birth to the first therapies of chronic inflammatory diseases on the basis of neuroendocrine immune targets. In addition, a new theory linked evolutionary medicine, neuroendocrine regulation of distribution of energy-rich fuels, and volume regulation that can explain many disease sequelae in patients with chronic inflammatory diseases.
