Psychosocial contributors to mental and physical health in patients with systemic lupus erythematosus

Positive psychosocial factors may protect against perceived stress in people with systemic lupus erythematosus with and without trauma history

OBJECTIVE

Trauma history is associated with SLE onset and worse patient-reported outcomes; perceived stress is associated with greater SLE disease activity. Stress perceptions vary in response to life events and may be influenced by psychosocial factors. In an SLE cohort, we examined whether stressful events associated with perceived stress, whether psychosocial factors affected perceived stress, and whether these relationships varied by prior trauma exposure.

METHODS

This is a cross-sectional analysis of data from the California Lupus Epidemiology Study, an adult SLE cohort. Multivariable linear regression analyses controlling for age, gender, educational attainment, income, SLE damage, comorbid conditions, glucocorticoids ≥7.5 mg/day and depression examined associations of recent stressful events (Life Events Inventory) and positive (resilience, self-efficacy, emotional support) and negative (social isolation) psychosocial factors with perceived stress. Analyses were stratified by lifetime trauma history (Brief Trauma Questionnaire (BTQ)) and by adverse childhood experiences (ACEs) in a subset.

RESULTS

Among 242 individuals with SLE, a greater number of recent stressful events was associated with greater perceived stress (beta (95% CI)=0.20 (0.07 to 0.33), p=0.003). Positive psychosocial factor score representing resilience, self-efficacy and emotional support was associated with lower perceived stress when accounting for number of stressful events (-0.67 (-0.94 to -0.40), p<0.0001); social isolation was associated with higher stress (0.20 (0.14 to 0.25), p<0.0001). In analyses stratified by BTQ trauma and ACEs, associations of psychosocial factors and perceived stress were similar between groups. However, the number of recent stressful events was significantly associated with perceived stress only for people with BTQ trauma (0.17 (0.05 to 0.29), p=0.0077) and ACEs (0.37 (0.15 to 0.58), p=0.0011).

CONCLUSION

Enhancing positive and lessening negative psychosocial factors may mitigate deleterious perceived stress, which may improve outcomes in SLE, even among individuals with a history of prior trauma who may be more vulnerable to recent stressful events.

Perceived Stress and Prediction of Worse Disease Activity and Symptoms in a Multiracial, Multiethnic Systemic Lupus Erythematosus Cohort

OBJECTIVE

Studies have suggested a potential link between traumatic experiences, psychological stress, and autoimmunity, but the impact of stress on disease activity and symptom severity in systemic lupus erythematosus (SLE) remains unclear. The present study was undertaken to examine whether increases in perceived stress independently associate with worse SLE disease outcomes over 3 years of follow-up.

METHODS

Participants were drawn from the California Lupus Epidemiology Study (CLUES). Stress was measured annually using the 4-item Perceived Stress Scale (PSS). Participants with increases of ≥0.5 SD in PSS score were defined as having an increase in stress. Four outcomes were measured at the year 3 follow-up visit: physician-assessed disease activity (Systemic Lupus Erythematosus Disease Activity Index); patient-reported disease activity (Systemic Lupus Activity Questionnaire); pain (Patient-Reported Outcomes Measurement Information System [PROMIS] pain interference scale); and fatigue (PROMIS fatigue scale). Multivariable linear regression evaluated longitudinal associations of increase in stress with all 4 outcomes while controlling for potential confounders.

RESULTS

The sample (n = 260) was 91% female, 36% Asian, 30% White, 22% Hispanic, and 11% African American; the mean ± SD age was 46 ± 14 years. In adjusted longitudinal analyses, increase in stress was independently associated with greater physician-assessed disease activity (P = 0.015), greater self-reported disease activity (P < 0.001), more pain (P = 0.019), and more fatigue (P < 0.001).

CONCLUSION

In a racially diverse sample of individuals with SLE, those who experienced an increase in stress had significantly worse disease activity and greater symptom burden at follow-up compared to those with stress levels that remained stable or declined. Findings underscore the need for interventions to bolster stress resilience and support effective coping strategies among individuals living with lupus.

Impact of demographic, clinical, and treatment compliance characteristics on quality of life of Venezuelan patients with systemic lupus erythematosus

BACKGROUND

We have here assessed the impact of demographic, clinical, and treatment compliance characteristics on health-related quality of life (HRQoL) of Venezuelan patients with systemic lupus erythematosus (SLE). We have used a disease-specific questionnaire, the Lupus Quality of Life (LupusQoL), validated in our patient population, to measure HRQoL.

METHODS

A cross-sectional study was conducted among 100 patients with SLE from outpatient clinics. Patients completed a form with demographic, clinical, and treatment compliance data, and the LupusQoL questionnaire. HRQoL was classified as better or worse according to previously established cut-off points for this patient population. Spearman's r test was used to determine the correlations between age, years of education, disease duration, SLEDAI, and SLICC-DI with the eight domains of the LupusQoL. Mann-Whitney U test was used to compare the HRQoL between the two groups of patients according to treatment compliance. Binomial logistic regression using the backward stepwise selection method was performed to identify the risk factors associated with each of the eight domains of the LupusQoL among patients with inactive (SLEDAI < 4) and active (SLEDAI ≥ 4) SLE.

RESULTS

HRQoL of our patients was classified as better in all domains of the LupusQoL. Age correlated negatively with all domains of the LupusQoL, except with "burden to others", and disease activity correlated negatively with all domains of the LupusQoL, except with "intimate relationships" and "burden to others" (p < 0.05). Patients who fully complied with indicated treatment had higher scores in "physical health" domain compared to patients who did not comply with at least one of the prescribed medications (p < 0.05). In patients with active SLE, a risk factor associated with worse "planning" and "intimate relationships" was advanced age, while having had SLE flare-ups in the previous six months was a risk factor associated with worse "physical health" (p < 0.05).

CONCLUSION

Age and disease activity were negatively correlated with almost all domains of the LupusQoL, and treatment compliance was associated with higher score in the "physical health" domain. Disease control and treatment compliance should be the main goals for a better HRQoL in our patients with SLE.

Effects of Exercise Intervention on Health-Related Quality of Life in Patients with Systemic Lupus Erythematosus: A Systematic Review and Meta-Analysis of Controlled Trials

Exercise and physical activity have been deemed as potentially beneficial for patients with systemic lupus erythematosus (SLE). This study aimed to evaluate the effects of exercise interventions on health-related quality of life in patients with SLE using a systematic review and meta-analysis. Randomized and non-randomized controlled trials published up to July 2021 were examined using the PubMed and Embase databases. Of the 1158 articles retrieved, nine were included for systematic review. Five of them were randomized controlled trials and these were assessed using meta-analysis. Hedges’ g effect size was 0.47; 95% (confidence interval 0.21–0.73; p < 0.001) for the physical health and function aspect of health-related quality of life. None of the other seven domains of the SF-36 showed a significant effect size. However, the latter finding was limited by the small number of available trials. In conclusion, this systematic review and meta-analysis supported that exercise intervention compared to usual care might be able to improve the physical functioning domain of health-related quality of life in patients with SLE. Future high-quality randomized controlled trials that incorporate disease-specific health-related quality of life measures are needed to elucidate the role of exercise on health-related quality of life in patients with SLE.

Personality in Autism Spectrum Disorder: Associations With Face Memory Deficit and Theory of Mind

OBJECTIVE

To examine the personality profiles of adults with autism spectrum disorder (ASD) using a standard personality assessment and to investigate the association between personality, ASD-related face memory deficit (FMD), and theory of mind (ToM). In a broader context, to examine whether there are distinct clinical phenotypes in the ASD population that have implications for personality development and treatment.

METHOD

Fifty-five adults with ASD and 22 neurotypical (NT) adults underwent a battery of neuropsychological tests, including measures of personality, face memory, and ToM. We compared ASD and NT groups in terms of their Personality Assessment Inventory (PAI) profiles. Additional analyses focused on the association between specific PAI scales and FMD. Performance on the Eyes Test was compared across groups and was examined in relation to FMD.

RESULTS

Adults with ASD demonstrated significant elevations on several PAI scales compared with NT adults. The presence of FMD was associated with differing PAI profiles among the ASD adults. The ASD adults with FMD scored significantly higher on scales that are sensitive to positive impression management and treatment rejection and significantly lower on scales that are sensitive to borderline personality, anxiety, depression, schizophrenia, and stress. There was a significant association between performance on the Eyes Test and FMD in the ASD group.

CONCLUSION

Adults with ASD have a unique personality profile. Further, ASD adults with FMD have reduced insight into their difficulties with emotional processing and may not be as sensitive as ASD adults without FMD to the emotions of others.

A scoping Review of tools used to assess patient Complexity in rheumatic disease

OBJECTIVE

Patients with rheumatic diseases often have multiple comorbidities which may impact well-being leading to high psychosocial complexity. This scoping review was undertaken to identify complexity measures/tools used in rheumatology that could help in planning and coordinating care.

METHODS

MEDLINE, EMBASE and CINAHL were searched from database inception to 14 December 2019 using keywords and Medical Subject Headings for "care coordination", "complexity" and selected rheumatic diseases and known complexity measures/tools. Articles describing the development or use of complexity measures/tools in patients with adult rheumatologic diagnoses were included regardless of study design. Included articles were evaluated for risk of bias where applicable.

RESULTS

The search yielded 407 articles, 37 underwent full-text review and 2 were identified during a hand search with 9 included articles. Only 2 complexity tools used in populations of adult patients with rheumatic disease were identified: the SLENQ and the INTERMED. The SLENQ is a 97-item patient needs questionnaire developed for patients with systemic lupus (n = 1 study describing tool development) and applied in 5 cross-sectional studies. Three studies (a practice article, trial and a cross-sectional study) applied the INTERMED, a clinical interview to ascertain complexity and support coordinated care, in patients with rheumatologic diagnoses.

CONCLUSIONS

There is limited information on the use of patient complexity measures/tools in rheumatology. Such tools could be applied to coordinate multidisciplinary care and improve patient experience and outcomes.

PATIENT CONTRIBUTION

This scoping review will be presented to patient research partners involved in co-designing a future study on patient complexity in rheumatic disease.

Racism-related stress and psychological distress: Black Women's Experiences Living with Lupus study

Disparate health consequences in African American women with systemic lupus erythematosus include greater severity of physical and psychological distress. Racism-related stress is also related to psychological distress correlates in this population. This study examined the relationships between racism-related experiences, psychological distress, and systemic lupus erythematosus activity in 430 African American women from the Black Women's Experiences Living with Lupus study. The structural equation model suggests that psychological distress mediates the relationship between racism-related stress and systemic lupus erythematosus disease activity. The impact of racism-related stress on systemic lupus erythematosus disease activity may occur primarily through their impact on psychological health variables. Implications for clinical care and future directions are explored.

"…Not Having the Real Support That We Need": Patients' Experiences with Ambiguity of Systemic Lupus Erythematosus and Erosion of Social Support

Objective

The patient‐specific experience of living with systemic lupus erythematosus (SLE) is underreported, particularly when studying factors associated with health‐related quality of life (HRQOL). Recent work has suggested that biomedical interventions are only partially predictive of HRQOL measures. A qualitative analysis of patient‐specific experiences can uncover additional root causes of impaired HRQOL in populations with SLE beyond the scope of quantitative questionnaires.

Methods

Consented adult patients with SLE classified by the American College of Rheumatology or Systemic Lupus International Collaborating Clinics were recruited. Ten semistructured interviews were conducted across six participants. Interviews were audio recorded, transcribed, and analyzed using an iterative process. Findings were presented to an interactive public forum with patients with SLE, family members and friends of patients, and health care professionals to assess accuracy.

Results

Four themes emerged from the interviews: 1) ambiguity, inconsistency, and lack of symptom predictability due to SLE disease courses; 2) poor communication with family, friends, and/or partners and poor bidirectional communication between health care providers and patients (informational support); 3) lack of validation for patients’ experiences (appraisal support); and 4) problematic aspects of social support, including negative support and patients’ inability to reciprocate support because of role changes. Data also indicate a reciprocal association between appraisal and informational sources of support.

Conclusion

Findings indicate that inadequate appraisal and informational support from informal and formal sources are salient factors influencing HRQOL among patients with SLE. Findings also point to the necessity of integrating community organizations, physicians, and friends and family of patients with SLE into capacity‐building interventions aimed at enhancing these sources of social support.

Psychological Factors that Link Socioeconomic Status to Depression/Anxiety in Patients with Systemic Lupus Erythematosus

Our analyses examined whether reserve capacity factors would explain the relationship between socioeconomic status (SES) and symptoms of depression/anxiety in patients with systemic lupus erythematosus (SLE). We assessed disease activity, depression/anxiety symptoms, and intrapersonal and interpersonal reserve capacity measures in 128 patients with SLE. Multiple meditational analyses revealed that intrapersonal and interpersonal psychosocial aspects of reserve capacity fully mediated the relationship between SES and depression/anxiety. Lower SES was indirectly associated with higher symptoms of depression and anxiety through the effects of psychosocial resilience. Interventions aimed at improving modifiable reserve capacity variables, such as self-esteem and optimism, may improve anxious/depressive symptomatology in patients with SLE.

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.

Cultural and quality-of-life considerations when administering corticosteroids as a therapeutic strategy for African American women living with systemic lupus erythematosus

OBJECTIVE

This study investigated the association among corticosteroids, emotional health, physical health, and work/regular activities of daily living in an ethnically diverse sample of women with systemic lupus erythematosus.

METHODS

A secondary analysis of data from the Medical University of South Carolina Lupus Database was conducted between confirmed cases of lupus (n = 224) and controls (n = 60). The sample comprised 57 Caucasian Americans, 141 Gullah African Americans (a subpopulation of African Americans from the Sea Islands of South Carolina and Georgia), and 86 non-Gullah African Americans.

RESULTS

Emotional health outcomes were better for women with systemic lupus erythematosus compared with controls. High emotional health scores may be influenced by cultural factors such as masking emotion, disease-coping mechanisms, religion, and strong familial and social support. Although a significant association was not detected between emotional health and work/regular activities of daily living, relationships were significant after adjusting for corticosteroid use.

CONCLUSION

These findings suggest corticosteroid use does influence the strength of the association between emotional health and work/regular activities of daily living.

Effective Self-Management Interventions for Patients With Lupus: Potential Impact of Peer Mentoring

Systemic lupus erythematosus (SLE) is associated with significant mortality, morbidity and cost for the individual patient and society. In the United States, African Americans (AAs) have 3-4 times greater prevalence of lupus, risk of developing lupus at an earlier age and lupus-related disease activity, organ damage and mortality compared with whites. Evidence-based self-management interventions that incorporate both social support and health education have reduced pain, improved function and delayed disability among patients with lupus. However, AAs and women are still disproportionately affected by lupus. This article presents the argument that peer mentoring may be an especially effective intervention approach for AA women with SLE. SLE peers with a track record of success in lupus management and have a personal perspective that clinicians often lack. This commonality and credibility can establish trust, increase communication and, in turn, decrease disparities in healthcare outcomes.

Intervention to Improve Quality of life for African-AmericaN lupus patients (IQAN): study protocol for a randomized controlled trial of a unique a la carte intervention approach to self-management of lupus in African Americans

BACKGROUND

Systemic Lupus Erythematosus (lupus) is a chronic autoimmune disease that can impact any organ system and result in life-threatening complications. African-Americans are at increased risk for morbidity and mortality from lupus. Self-management programs have demonstrated significant improvements in health distress, self-reported global health, and activity limitation among people with lupus. Despite benefits, arthritis self-management education has reached only a limited number of people. Self-selection of program could improve such trends. The aim of the current study is to test a novel intervention to improve quality of life, decrease indicators of depression, and reduce perceived and biological indicators of stress in African-American lupus patients in South Carolina.

METHODS/DESIGN

In a three armed randomized, wait list controlled trial, we will evaluate the effectiveness of a patient-centered 'a-la-carte' approach that offers subjects a variety of modes of interaction from which they can choose as many or few as they wish, compared to a 'set menu' approach and usual care. This unique 'a-la-carte' self-management program will be offered to 50 African-American lupus patients participating in a longitudinal observational web-based SLE Database at the Medical University of South Carolina. Each individualized intervention plan will include 1-4 options, including a mail-delivered arthritis kit, addition and access to an online message board, participation in a support group, and enrollment in a local self-management program. A 'set menu' control group of 50 lupus patients will be offered a standardized chronic disease self-management program only, and a control group of 50 lupus patients will receive usual care. Outcomes will include changes in (a) health behaviors, (b) health status, (c) health care utilization, and (d) biological markers (urinary catecholamines).

DISCUSSION

Such a culturally sensitive educational intervention which includes self-selection of program components has the potential to improve disparate trends in quality of life, disease activity, depression, and stress among African-American lupus patients, as better outcomes have been documented when participants are able to choose/dictate the content and/or pace of the respective treatment/intervention program. Since there is currently no "gold standard" self-management program specifically for lupus, this project may have a considerable impact on future research and policy decisions.

Insomnia symptoms, perceived stress and coping strategies in patients with systemic lupus erythematosus

Objective

The aim of this study is to evaluate perceived stress and coping strategies in individuals with systemic lupus erythematosus (SLE) according to the presence of insomnia symptoms, using a set of variables that include anxiety and depressive symptoms evaluation.

Methods

Ninety SLE women were evaluated in a cross-sectional study using the Perceived Stress Scale (PSS), Brief COPE, Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Beck Depression Inventory (BDI) and Self-rating Anxiety Scale (SAS).

Results

Individuals with insomnia symptoms ( n = 57, 66%) presented higher PSS ( p < 0.001), PSQI ( p < 0.0001), BDI, ( p < 0.0001) scores and showed less-effective coping strategies such as the use of behavioral disengagement ( p = 0.04), self-blame ( p = 0.02) and emotional-focused coping ( p = 0.001). In a multi-regression model ISI was the independent determinant of high PSS and of behavioral disengagement; PSQI was the only determinant of self-blame ( p = 0.02) and emotional-focused coping.

Conclusions

SLE individuals with insomnia symptoms show high levels of perceived stress and more frequent use of disengaging and emotional-focused coping strategies. This body of evidence suggests that individuals with SLE and comorbid insomnia symptoms may therefore require additional interventions for insomnia.

A review of health related quality of life in systemic lupus erythematosus

Health-related quality of life (HRQoL) is an important outcome measure in patients with systemic lupus erythematosus (SLE). A review was undertaken of the literature relating to HRQoL in SLE. MEDLINE, EMBASE, CINAHL, Allied and Complimentary Medicine were searched to locate full papers in the English language reporting on HRQoL in adult SLE patients published between 1990 and 2005. In total 53 papers were included and the review was subdivided into: 1) description of HRQoL in SLE patients; 2) HRQoL and disease activity and/or damage; 3) the impact of other variables on HRQoL; and 4) HRQoL measures used in clinical trials in SLE patients. The findings were as follows: HRQoL is reduced in SLE patients; HRQoL is not correlated to disease activity or damage; age appears to have a negative impact on HRQoL especially physical health but the effect of disease duration is unclear; other potentially modifiable variables such as fatigue and psychosocial factors impact on HRQoL in a complex manner; and HRQoL measures which are sensitive to change should be an essential outcome measure in all clinical trials on SLE patients.

Psychosocial research on systemic lupus erythematosus: a literature review

This article is the first to review published research on psychosocial factors and behavioral interventions related to systemic lupus erythematosus (SLE). The first section presents descriptive studies, followed by studies that investigate psychosocial factors as predictor and outcome variables. These studies demonstrate that the consideration of psychosocial factors is critical to understanding the disease experience of persons with SLE. Next, studies of behavioral interventions are presented, leading to the conclusion that randomized controlled trials are essential yet rare. The final section highlights limitations of the extant literature and suggests directions for future research and recommendations for clinicians.

The illness experience of youth with lupus/mixed connective tissue disease: a mixed methods analysis of patient and parent perspectives

OBJECTIVE

We aimed to develop a model of the illness experience for youth with systemic lupus erythematosus (SLE)/mixed connective tissue disease (MCTD).

METHODS

We conducted 32 semi-structured interviews with 16 outpatient youth with SLE/MCTD, age 11 to 22 years, and their parents. We qualitatively defined key features of illness for families and distinguished profiles of youth adapting well vs poorly to SLE/MCTD. We then related these profiles to features of illness, patient-level attributes and outcomes.

RESULTS

Experiences with SLE/MCTD grouped into five themes: managing disease, limitations, stigma, illness uncertainty and psychological coping. Youth adapting well experienced minimal challenges in these areas. Youth adapting poorly (4/16) experienced significant challenges in >1 thematic area, and were older with lower socioeconomic status, quality of life and psychosocial functioning, and increased disease-related morbidity. They also described suboptimal treatment adherence, healthcare utilization and transition to adult care. These findings support a dynamic model in which illness adaptation and outcomes are shaped by patient characteristics and five central illness-related challenges.

CONCLUSION

Further testing of our model of illness experience may help guide comprehensive and personalized care of youth with SLE/MCTD, with targeted supports for youth at risk for negative adaptation to illness and poor outcomes.

Initial evidence for the link between activities and health: Associations between a balance of activities, functioning and serum levels of cytokines and C-reactive protein

Growing evidence shows interrelations of psychological factors, neurological and immunological processes. Therefore, constructs like a balance of activities, the so called "occupational balance", could also have biological correlates. The aim of this study was to investigate potential associations between occupational balance, functioning, cytokines and C-reactive protein (CRP) in patients suffering from a chronic inflammatory disease like rheumatoid arthritis (RA) and healthy people. Moreover, we wanted to explore potential differences in gender and employment status. A descriptive study in patients with RA and healthy people was conducted using the Occupational Balance-Questionnaire (OB-Quest) and the Short-Form 36 Health Survey (SF-36). Serum levels of cytokines, such as interleukin 6 (IL-6) and 8 (IL-8), interferon alpha (INFα), tumour necrosis factor alpha (TNFα), rheumatoid factor (RF) and of CRP were measured. Descriptive statistics, as well as Mann-Whitney U tests and Spearmen's rank correlation coefficients (rs) were calculated. One-hundred-thirty-two patients with RA and 76 healthy people participated. Occupational balance was associated with functioning, cytokines and CRP. The strongest associations were identified in the unemployed healthy-people sample with cytokines and CRP being within the normal range. For example, the OB-Quest item challenging activities was associated with IL-8 (rs=-0.63, p=0.04) and the SF-36 sub-scale bodily pain was associated with IFNα (rs=-0.69, p=0.02). The items rest and sleep (rs=-0.71, p=0.01) and variety of different activities (rs=-0.74, p<0.01) correlated with the SF-36 sub-scale social functioning. Employed and unemployed people differed in their age and CRP levels. Additionally, gender differences were found in two OB-Quest items in that fewer women were able to adapt their activities to changing living conditions and fewer men were overstressed. In conclusion, we found preliminary biological evidence for the link between occupation and health in that the concepts encompassed in the construct of occupational balance were associated with functioning, cytokines and CRP.

Social Support and Self-Reported Stress Levels in a Predominantly African American Sample of Women with Systemic Lupus Erythematosus

Lupus patients should avoid stress because physical or emotional stress can affect overall physical health. It has been suggested that social support has a positive influence on health status, but there is a lack of information in the literature on the association between the two among lupus patients. The current study investigated the association between social support and self-reported stress and coping status among African American women with lupus using data collected from two linked cross-sectional surveys. No social support differences in groups of high and low stress/coping were revealed; a duplicate study with a larger sample size is required.

Social capital: a novel platform for understanding social determinants of health in systemic lupus erythematosus

OBJECTIVE

The objective of this paper is to introduce the concept of social capital as a unique and distinct entity from the traditional psychosocial factors of social support, depressive symptoms, and self-efficacy in systemic lupus erythematosus (SLE) patients, and to evaluate how social capital varies in an SLE sample according to demographic, clinical, and psychosocial variables.

METHODS

In a cross-sectional study, SLE patients completed the Adapted Social Capital Assessment Tool (A-SCAT), which measures cognitive and structural social capital. Patients also completed measures of social support, depressive symptoms, and SLE self-efficacy. Correlations were evaluated between social capital scores and demographic, clinical, and psychosocial variables.

RESULTS

We recruited 89 patients (mean age: 39 ± 15 years old, 83 (93): female; mean SLEDAI: 4; mean SLICC 1). The mean A-SCAT score was 34 ± 15 (normal: 0-71); higher scores were associated with female sex, older age, higher education, Caucasian race, and non-Medicaid insurance (p ≤ 0.03 for all); associations were attributable to structural social capital. Social capital was not associated with depressive symptoms, self-efficacy, or affectionate and interaction social support, but was associated with informational and tangible social support (r = 0.39, r = 0.26, respectively, p ≤ 0.02). There were no associations between SLEDAI and SLICC and social capital, social support, and depressive symptoms.

CONCLUSIONS

Social capital is a novel construct that, like other traditional psychosocial measures, addresses aspects of SLE not reflected by markers of disease activity. Social capital, however, is distinct from traditional psychosocial measures and offers a new platform on which ideas of social connectedness can broaden our understanding of health and chronic illness.

Social Determinants of Health, the Chronic Care Model, and Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is a chronic inflammatory rheumatic disease that disproportionately affects African Americans and other minorities in the USA. Public health attention to SLE has been predominantly epidemiological. To better understand the effects of this cumulative disadvantage and ultimately improve the delivery of care, specifically in the context of SLE, we propose that more research attention to the social determinants of SLE is warranted and more transdisciplinary approaches are necessary to appropriately address identified social determinants of SLE. Further, we suggest drawing from the chronic care model (CCM) for an understanding of how community-level factors may exacerbate disparities explored within social determinant frameworks or facilitate better delivery of care for SLE patients. Grounded in social determinants of health (SDH) frameworks and the CCM, this paper presents issues relative to accessibility to suggest that more transdisciplinary research focused on the role of place could improve care for SLE patients, particularly the most vulnerable patients. It is our hope that this paper will serve as a springboard for future studies to more effectively connect social determinants of health with the chronic care model and thus more comprehensively address adverse health trajectories in SLE and other chronic conditions.

Problematic social support from patients' perspective: the case of systemic lupus erythematosus

Several studies demonstrated the importance of psychosocial factors, like social support, for understanding the experience of people with Systemic Lupus Erythematosus (SLE). Less information is available on "problematic support"; that is, instances of support that are perceived as non-supportive, even though the provider's actions may be well intended. Aim of this qualitative study was to explore the experiences of problematic support from SLE patients' perspective. Nine women with SLE were interviewed and transcripts were analyzed through qualitative content analysis. Three main types of problematic social support were indentified. Oppressive support describes social support offers characterized by excessive worries and unwanted advices. Support denying the illness is characterized by a neglect of the disease or of its consequences. Support based on divergent illness representations is perceived as not punctual and not in line with patients' actual clinical condition. This study confirms the complexity of providing useful support to SLE patients and suggest that also people living close to patients should represent a target of interventions.

Photodermatoses: environmentally induced conditions with high psychological impact

Photodermatoses are a group of skin disorders caused or exacerbated by ultraviolet and/or visible radiation, which collectively affect a high proportion of the population and substantially affect quality of life (QoL). Our objective was to assess the psychological impact of these conditions. Patients with a range of photodermatoses diagnosed at a specialist investigation centre in the UK completed questionnaires evaluating (i) anxiety and (ii) depression, using the Hospital Anxiety and Depression Scale (HADS), (iii) social anxiety, using the Fear of Negative Evaluation measure (FNE), (iv) coping strategies (brief COPE) and (v) QoL, using the Dermatology Life Quality Index (DLQI). Questionnaires were returned by 185 of 260 patients (71.1% response rate). Mean age was 50.2 years (SD 14.5, range 20-85), 80.3% female. Polymorphic light eruption was the most common diagnosis, followed by photoaggravated eczema, other photoaggravated dermatological conditions and solar urticaria. Across the sample, high percentages, i.e. 23% and 7.9% of individuals, showed scores indicating clinical levels of anxiety and depression, respectively. Facial involvement was a strong indicator for depression (t = 2.7, p < 0.01). In regression analyses psychological factors (particularly depression and adaptive coping) were the principle predictors of QoL, accounting for 17.7% of the variance (F = 7.61, p < 0.01), while clinical variables accounted for an additional 10.1% (F = 8.96, p < 0.01), with number of months/year affected exerting a significant effect (p < 0.01). This study demonstrates the high psychological comorbidity of these conditions; more awareness of this is required, with adoption of a biopsychosocial approach to their management.

The health education for lupus study: a randomized controlled cognitive-behavioral intervention targeting psychosocial adjustment and quality of life in adolescent females with systemic lupus erythematosus

INTRODUCTION

To examine in a randomize controlled feasibility clinical trial the efficacy of a cognitive-behavioral intervention designed to manage pain, enhance disease adjustment and adaptation and improve quality of life among female adolescents with systemic lupus erythematosus.

METHODS

Female adolescents (n = 53) ranging in age from 12 to 18 years were randomly assigned to 1 of 3 groups including a cognitive-behavioral intervention, an education-only arm and a no-contact control group. Participants were assessed at baseline, postintervention and at 3- and 6-month intervals after completion of the intervention.

RESULTS

No significant differences were revealed among the 3 treatment arms for any of the dependent measures at any of the assessment points. For the mediator variables, a posthoc secondary analysis did reveal increases in coping skills from baseline to postintervention among the participants in the cognitive-behavioral intervention group compared with both the no-contact control group and the education-only group.

CONCLUSION

Although no differences were detected in the primary outcome, a possible effect on coping of female adolescents with systemic lupus erythematosus was detected in this feasibility study. Whether the impact of training in the area of coping was of sufficient magnitude to generalize to other areas of functioning, such as adjustment and adaptation, is unclear. Future phase III randomized trials will be needed to assess additional coping models and to evaluate the dose of training and its influence on pain management, adjustment and health-related quality of life.

Listening to lupus patients and families: fine tuning the assessment

Given the chronicity and uncertainty of lupus, patients and their family members will face physical, financial, social, and emotional challenges that can be overwhelming. This article records the experiences of three different families affected by lupus. Although these patients and families are very different, their perspectives identify common emotional challenges. Understanding these experiences from their perspectives can help facilitate an assessment that is highly attuned to the potential psychosocial impact of lupus on the patient and the family.

Locus of control and lupus: patients' beliefs, perspectives, and disease activity

Patients with lupus often experience a high degree of psychological symptoms such as anxiety, depression, and mood disorders that can influence their beliefs and perceptions of their illness. The purpose of the study was to examine how a patient's self-reported psychosocial needs (depression and anxiety) and beliefs about how much control they have over their health (health locus of control) influences their perception of disease chronicity and acuity. The study findings were based on a survey of 378 patients self-diagnosed with lupus.

The relationship between alexithymia and psychological factors in systemic lupus erythematosus

BACKGROUND

Alexithymia has been described as an important dimension in several medical diseases. Systemic lupus erythematosus (SLE) is a chronic condition characterized by unpredictable clinical manifestations. Our aim is to reveal which factors (psychological factors and quality of life dimensions) are associated with alexithymia in SLE patients.

METHODS

Fifty-three sequential SLE patients (ACR criteria) and 41 asthma patients were studied by means of validated scales for alexithymia (Toronto Alexithymia Scale), psychopathology (Brief Symptom Inventory, Hospital Anxiety and Depression Scale), personality dimensions (NEO-FFI), and quality of life (Short Form-36 Health Survey). Systemic lupus erythematosus patient's clinical and laboratorial evaluation was performed by indicators of activity (Systemic Lupus Erythematosus Disease Activity Index) of accumulated damage (Systemic Lupus International Collaborating Clinics/ACR Damage Index), length of disease, and therapy.

RESULTS

An association between alexithymia and psychopathological symptoms, and personality and quality of life dimensions was found. By means of multiple regression analysis, openness and depression were the 2 predictors for alexithymia in SLE patients. We found a high prevalence rate of alexithymia in SLE patients; however, when controlling for depression symptoms (Hospital Anxiety and Depression Scale-Depression, <7), we found a lower percentage of alexithymic traits than that of the total sample of SLE.

CONCLUSION

Alexithymia was associated with psychological distress and with quality of life impairment. Understanding the role of psychological factors in SLE patients may contribute to a more comprehensive perspective of the disease, its impact on patient's daily routine, and how patients adapt emotionally to a chronic disease.

Quality of life in patients with systemic lupus erythematosus (SLE) compared with related controls within a unique African American population

The patient's perspective of how their health affects their function is health-related quality of life (HRQOL). HRQOL is poorer in patients with systemic lupus erythematosus (SLE). Few HRQOL studies in SLE patients have focused on African Americans despite an increased disease burden compared with Caucasians. The African American Gullah population of South Carolina has a homogeneous genetic and environmental background and a high prevalence of multi-patient families with SLE. Demographics, medical history, and Short-Form 36 (SF-36) were measured within a cohort of Gullah SLE cases and related controls. Compared with related controls (n = 37), cases (n = 89) had a lower Physical Component Summary (PCS, 41.8 vs. 52.3, p < 0.01), but not Mental Component Summary (MCS, 55.0 vs. 56.0, p = 0.70). The difference in PCS was no longer significant upon adjustment for working status, disability, and medical conditions. None of the 11 SLE American College of Rheumatology criteria, disease duration, or Systemic Lupus International Collaborating Clinics Damage Index were associated with either PCS or MCS. Cases and controls had similar MCS scores. We hypothesize that this lack of effect of SLE on MCS may be due to disease-coping mechanisms interplaying with cultural factors unique to the Gullah.

Social support and health in patients with systemic lupus erythematosus: A literature review

In the last decades, with the improvement of life expectancies for systemic lupus erythematosus (SLE) patients, the relationship between social support and health in this population has received a considerable amount of attention in behavioural medicine and health psychology. This paper is the first to review research studies which specifically investigated perceived social support in relation to SLE patients’ health outcomes (quality of life, disease activity and damage). Starting with a descriptive approach to social support perceived by patients with SLE, the research evidence on the impact of social support on health is presented. These studies demonstrate that the consideration of social support is critical in predicting disease activity, damage and quality of life (both physical and psychological components) although the precise ways in which social support contributes to health are not yet completely understood. Discussing the results, the authors offer some suggestions which could guide further research in this field. Finally, clinical and non-clinical implications of the findings are discussed.

Psychosocial dimensions of SLE: implications for the health care team

Background:

The purpose of this exploratory study was threefold, ie, to clarify the unique psychosocial challenges facing those living with systemic lupus erythematosus (SLE), to distinguish which sociodemographic variables impact the lives of SLE patients, and generate knowledge regarding the way patients perceive SLE medication regimens.

Methods:

This was a cross-sectional exploratory study in 378 patients diagnosed with SLE and receiving services from the SLE Lupus Foundation in New York City. In addition to sociodemographic variables, the instrument used consisted of two scales, ie, the Systemic Lupus Erythematosus Needs Questionnaire (SLENQ) and the Multidimensional Health Locus of Control Scale, as well as questions regarding subjective perceptions of side effects from SLE medication.

Results:

The highest general cause of self-reported depressive and anxious feelings was changes in appearance due to SLE, and limitations in physical abilities due to SLE (primarily from muscle and joint pain). The higher the sense of control over SLE, the less likely respondents were to report feeling depressed and anxious. African-American and Hispanic SLE patients reported a higher level of unmet psychological needs due to SLE than did their other ethnic counterparts. Weight gain and hair loss were the most likely medication side effects and also the most likely causes of SLE-related depression and anxiety.

Conclusion:

Those living with SLE are at risk for feelings of depression and anxiety. African-American and Hispanic women are at higher risk for these emotional states. Comprehensive assessment across the disciplines should screen this group of patients for depression and anxiety, and be prepared to refer them to patient education and social work counseling as indicated.

Prevalence of depression and depressive symptoms in patients with systemic lupus erythematosus: Iranian experience

Psychiatric disorders including depression represent clinical manifestation of systemic lupus erythematosus (SLE). Recognition of depression in SLE patients is of utmost importance since it is treatable and can be of fatal consequences if unrecognized. This study was conducted to determine the prevalence of depression and depressive symptoms in SLE patients in terms of age, gender, disease duration and severity, and duration of steroid treatment in SLE patients. Eighty-five SLE patients (77 women, 8 men) with verified SLE diagnosis completed Beck's depression inventory, a self-reported measure of depression. Clinical data on disease and treatment were obtained from patient files. In total, 60% of patients achieved scores indicating depression. The most common depressive symptoms in participants were fatigue and weakness (88.2%), irritability (82.3%), sadness (77.6%), and somatic preoccupation (76.4%), while the least common symptoms were weight loss (34.1%), low level of energy (28.2%), and suicide ideation (10.5%). There was a significant difference between the disease activity and the severity of depression (P = 0.0001). Our findings show higher prevalence of depression in our sample in comparison with previous studies, suggesting that the prevalence of depression varies across different populations. Severity of depression increases with more severe disease course.

The role and effect of complementary and alternative medicine in systemic lupus erythematosus

The use of complementary and alternative medicine (CAM) is common among patients with systemic lupus erythematosus (SLE), especially those with active disease who often have poorer quality of life and significant unmet needs. It is important for the rheumatologist to be aware of these therapies and to ask the patient with SLE about their active use or future interest in CAM. Future studies on the effectiveness of the aforementioned therapies will be crucial to find better ways for the rheumatologist to integrate their use into the care of the patient with SLE.

Factors influencing the health related quality of life in patients with systemic lupus erythematosus: long-term results (2001—2005) of patients in the German Lupus Erythematosus Self-Help Organization (LULA Study)

The aim of this longitudinal study was to determine disease-specific and individual factors associated with health-related quality of life (HRQOL) in a cohort of patients with systemic lupus erythematosus (SLE) organized in the German Lupus Erythematosus Self-Help Organization. Three hundred and seventeen patients aged between 11 and 77 years participated annually in five surveys carried out between 2001 and 2005. Regression analyses were carried out for physical and mental HRQOL as dependent variables. Factors influencing HRQOL were the respective HRQOL scores of the previous year, SLE activity as measured by the Systemic Lupus Activity Questionnaire (SLAQ), and impairments in everyday life. Social support indicated by living in marriage or in a marriage-like partnership had a positive influence on both mental and physical HRQOL, whereas individual factors such as education seemed to be of minor importance.

The LupusQoL and Associations with Demographics and Clinical Measurements in Patients with Systemic Lupus Erythematosus

Objective.

Having developed and validated a disease-specific health-related quality of life (HRQOL) measure for patients with systemic lupus erythematosus (SLE), the LupusQoL, we determined its relationship to demographic and clinical measurements in a group of patients with SLE.

Methods.

A group of 322 outpatients completed the LupusQoL. Demographic (age, sex, marital status, ethnicity) and clinical variables (disease duration, disease activity, damage) were recorded. Associations between the 8 LupusQoL domains and age, disease duration, disease activity, and damage were explored using Spearman’s correlation coefficients. Differences in LupusQoL scores were examined for sex and marital status using the Mann-Whitney U test. Ethnic groups were compared using ANOVA.

Results.

All domains of LupusQoL were impaired, with fatigue (56.3) being the worst affected and body image (80.0) the least. The correlations between the LupusQoL domain scores and age (r = −0.01 to −0.22) and disease duration (r = 0 to 0.16) were absent or weak. Similarly, there were no significant differences in the LupusQoL scores regarding sex, marital status, or the 3 main ethnic groups (Black-Caribbean, Asian, White). Although there were statistically significant correlations between the scores of the LupusQoL domains and some scores of the British Isles Lupus Assessment Group index (r = −0.22 to 0.09) and the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (r = −0.29 to 0.21), these were weak.

Conclusion.

HRQOL was impaired in this cohort of outpatients with SLE as assessed by the validated lupus-specific LupusQoL. There were no clinically important associations between the 8 domains of the LupusQoL and clinical or demographic variables in this group of patients. Thus, the LupusQoL is a relatively independent outcome measure in patients with SLE.

Comparison of a self-report and performance-based test of disability in people with systemic lupus erythematosus

PURPOSE

The purpose of this study was to examine functional ability in people with SLE by comparing a self-report and a performance-based test.

METHOD

Fifteen women with SLE and 15 healthy controls participated in this study. Participants completed a self report of daily living skills, the Health Assessment Questionnaire (HAQ). Actual performance during activities of daily living was evaluated with the Assessment of Motor and Process Skills (AMPS). Measures of cognition and disease activity were also collected.

RESULTS

HAQ scores of the participants with SLE indicated only very mild disability while scores on the AMPS indicated ineffective skill performance and potential safety risks. In the participants with SLE, cognitive status correlated significantly with the processing component (r(s) = 0.62, p < 0.05) and disease severity correlated with the motor component of the AMPS (r(s) = 0.84, p < 0.001). The HAQ did not correlate with the AMPS.

CONCLUSIONS

This study suggests that cognitive deficits were more related to scores on the performance-based test of functional ability rather than the self-report. The performance-based test appeared to provide information that was not gained through self-report and measures of disease activity and gross cognition.

Psychological stress increases expression of IL-10 and its homolog IL-19 via beta-adrenoceptor activation: reversal by the anxiolytic chlordiazepoxide

Recent studies from our laboratory indicate that psychological stress is a potent inducer of the anti-inflammatory cytokine interleukin (IL)-10, raising the possibility that the IL-10 family of cytokines may be key mediators of stress-induced immunosuppression. In this study we examined the impact of psychological stress (restraint stress) on expression of IL-10, and the novel IL-10 family members IL-19, IL-20 and IL-24 in mouse spleen following an in vivo challenge with lipopolysaccharide (LPS). We found that stressor exposure significantly augmented LPS-induced IL-10 expression. Similarly, IL-19 expression was induced by LPS, and this was significantly enhanced by restraint stress. In contrast, expression of IL-24 was not significantly altered by LPS or stress, and expression of IL-20 was largely not detectable in vivo in either saline or LPS-treated animals. Consistent with a role for sympathetic nervous system (SNS) activation in stress-induced immune regulation, the sympathetic neurotransmitter noradrenaline increased LPS-induced IL-10 and IL-19 expression in splenocytes and dendritic cells, and the ability of noradrenaline to induce expression of these cytokines was blocked by pre-treatment with the beta-adrenoceptor antagonist propranolol. Similarly, pre-treatment of mice with the peripherally acting beta-adrenoceptor antagonist nadolol completely blocked the stress-induced increase in IL-10 and IL-19 mRNA expression. Finally, pre-treatment with the benzodiazepine anxiolytic chlordiazepoxide prevented the stress-induced increase in IL-10 and IL-19 expression. Taken together, these data demonstrate that psychological stress induces expression of the IL-10 and its homolog IL-19 via activation of beta-adrenoceptors, and the ability of stress to induce these cytokines is prevented by treatment with the anxiolytic chlordiazepoxide. The findings suggest that stress enhances the production of immunosuppressive cytokines, which may impact on stress-related disease processes.

The influence of positive experiences on depression and quality of life in persons with multiple sclerosis

PURPOSE

This correlational study determined the extent to which positive, rather than negative, experiences influence depressive symptoms and quality of life in persons with multiple sclerosis (MS).

METHOD

Data collected during the 7th year of an ongoing longitudinal study of quality of life in community-dwelling persons with MS were used for this analysis.

FINDINGS

Higher number of positive experiences was associated with fewer depressive symptoms, less functional limitations, and better quality of life. Using hierarchical multiple regression, age, education, functional limitations, and positive experiences accounted for 21.7% of the variance in depressive symptoms, and functional limitations, positive experiences, and depressive symptoms explained 58% of the variance in quality of life.

CONCLUSIONS

Higher number of positive experiences predicted lower levels of depressive symptoms, even while taking disease-related functional limitations into account. Incorporating positive experiences into daily life may improve quality of life, even when battling depression and substantial limitations in functioning.

A multiethnic, multicenter cohort of patients with systemic lupus erythematosus (SLE) as a model for the study of ethnic disparities in SLE

OBJECTIVE

To examine health disparities as a function of ethnicity using data from LUpus in MInorities, NAture versus nurture (LUMINA), a longitudinal study of patients with systemic lupus erythematosus (SLE); to build an explanatory model of how ethnic disparities occur in this setting; and to suggest appropriate interventions.

METHODS

LUMINA patients (meeting American College of Rheumatology criteria for SLE) ages >/=16 years of African American, Hispanic (from Texas), Hispanic (from Puerto Rico), or Caucasian ethnicity were studied. In addition to examining the basic features of the cohort, we examined, by univariable and multivariable analyses, the factors associated with disease activity, damage accrual, lupus nephritis, and mortality. An empiric model based on the data presented (and the literature reviewed) was derived to explain the disparities observed.

RESULTS

There were substantial differences in the socioeconomic/demographic, clinical, and genetic features among patients from the different ethnic groups, with Texan Hispanic and African American patients exhibiting overall a lower socioeconomic status, different genetic associations, more serious disease at a younger age, and worse intermediate and final outcomes than the Caucasian and Puerto Rican Hispanic patients. A model of disease outcome as a function of the disparities observed was created.

CONCLUSION

Ethnic disparities occur in SLE. Environmental, socioeconomic/demographic, psychosocial, genetic, and clinical factors play an important role as determinants of the ethnic differences observed. Measures aimed at eliminating these disparities are suggested while further research is conducted to elucidate the basis of these disparities and their changes at the societal level and to eliminate the gap between the rich and the poor.

Major depressive disorder and disease activity in systemic lupus erythematosus

The association between psychosocial factors and systemic lupus erythematosus (SLE) is still a matter of discussion. Mood disorders may represent neuropsychiatric manifestations of SLE disease activity or may be a consequence of the stress of having a chronic major disease. We examined the hypothesis that SLE disease activity is related to the presence and severity of major depression in patients with SLE. Seventy-one patients with SLE were evaluated for the presence and intensity of major depressive disorder, psychosocial stressors, functional disability, SLE disease activity, and cumulative damage. Patients with major depression presented a trend toward having greater severity of SLE disease activity compared with those without major depression (P = .056). Major depression was also associated with life events (P = .017) and hassles (P < .001). Reinforcing these findings, depression severity was directly correlated with disease activity (r = 0.26, P = .026) and with functional disability (r = 0.46, P < .001). Moreover, multiple linear regression analysis, controlling for stressful life events and previous major depressive episodes, demonstrated that SLE disease activity still was associated with depression severity (P = .014). In conclusion, these results support the hypothesis that SLE disease activity is a potential risk factor for the presence and severity of major depression in patients with SLE. Whether major depression in active SLE is a central nervous system manifestation of the disease that is mediated by an autoimmune mechanism deserves further research.

Fluctuation in self-perceived stress and increased risk of flare in patients with lupus nephritis carrying the serotonin receptor 1A -1019 G allele

OBJECTIVE

Stress is believed to be a risk factor for systemic lupus erythematosus (SLE) flare. Two serotonin-related gene polymorphisms, the serotonin receptor 1A (5-HT1A) polymorphism at -1019C>G and the serotonin transporter LS polymorphism, have been reported to affect stress-related behaviors. The purpose of this study was to assess the relationship between self-perceived stress (SPS), variability in SPS, and the 2 serotonin-related gene polymorphisms as risk factors for SLE flare.

METHODS

Seventy-seven SLE patients (50 with lupus nephritis) were evaluated every 2 months (mean +/- SD total followup 18.5 +/- 8.5 months), and patients recorded their daily SPS levels (0-10 scale). Values for mean SPS and coefficient of variation (CV) for SPS were calculated from the 60-day block of daily measurements between study visits. Serotonin-related gene polymorphism genotypes were determined by polymerase chain reaction-based methods.

RESULTS

Of the 77 patients, 53 experienced 80 flares of SLE (32 renal flares) based on prespecified criteria. Multivariate analysis revealed that whereas neither the serotonin-related gene polymorphisms nor the mean SPS was predictive of an SLE flare, an increased CV for SPS was predictive (P = 0.0031). Interaction between the CV for SPS and the 5-HT1A -1019C>G polymorphism was also found to be a predictor of SLE flare (P = 0.0039). Subset analysis revealed that only in lupus nephritis patients were increasing CVs for SPS (P = 0.0002) and the interaction between CVs for SPS and 5-HT1A (P < 0.0001) predictive of a flare. Odds ratio curves demonstrated that the predictive effect of increasing CVs for SPS required the presence of the 5-HT1A -1019 G allele, but appeared to be independent of the G allele number.

CONCLUSION

Fluctuation in the level of SPS is a risk factor for the onset of flare in SLE patients with major renal manifestations when it occurs on the background of a stress-related susceptibility gene (the 5-HT1A -1019 G allele).

Stress and coping strategies in systemic lupus erythematosus: a review

Systemic lupus erythematosus (SLE), a chronic and unpredictable disease accompanied by functional disability and a possible involvement of the central nervous system, leads to considerable psychological distress. A review of studies on stress and/or coping strategies in SLE since 1990 is presented. Many studies have investigated the place of major and minor stress and coping strategies in SLE morbidity (disease activity, organ damage, and physical and mental components of quality of life). Stress as a causal factor is not proved, but it seems to act as an exacerbating factor in disease activity and to have an impact on the quality of life. Coping strategies are more consistently associated with quality of life than with disease activity. Organ damage appears to be less associated with psychosocial factors than disease activity or quality of life. Despite the limitations of these studies, therapeutic interventions should be proposed to reduce psychological distress, to improve the quality of life and possibly to moderate the evolution of the disease.

Major life stress, coping styles, and social support in relation to psychological distress in patients with systemic lupus erythematosus

The objective of this study was to examine psychological processes in systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) patients in relation to measures of life stress, coping styles, social support and cognitive ability. Fifty-two SLE patients without overt neuropsychiatric symptoms, 29 RA patients and 27 healthy controls completed measures of depression, mood, disease activity, perceived health, stressful life events, coping, and social support. Variables entered into the multiple regression analysis following principal component analysis were: group, major difficult event, major life threatening event, disengaging coping, emotional coping, social support, and cognitive impairment. Depressive symptoms were associated with SLE group status (P < 0.001), major life-threatening events (P < 0.01), disengage coping (P < 0.001) and emotional coping (P < 0.05). SLE group status (P < 0.05), disengage coping (P < 0.05) and emotional coping (P < 0.05) were associated with current distressed mood. SLE patients without overt, major neuropsychiatric symptoms had greater psychological distress compared to RA and control subjects. Increased depressive symptoms and distressed mood state in SLE patients were related to use of disengaging and emotional coping styles. These findings are limited to SLE patients with no overt neuropsychiatric illness and low disease activity, suggesting the need for future studies with a greater variety of SLE patients. Interventions aimed at improving active coping and minimizing emotional response to stress may lower psychological distress in SLE patients with mild disease.

Relationship of quality of life and physical function measures with disease activity in children with systemic lupus erythematosus

The objective of this study is to assess relationship of systemic lupus erythematosus (SLE) activity with quality of life (QOL) and physical function and determine which is more closely correlated with SLE activity in children; and identify factors critical to children's QOL. In this cross-sectional study, children with SLE and parents completed corresponding versions of physical function (Childhood Health Assessment Questionnaire CHAQ), and QOL (Pediatric Quality of Life Inventory-PedsQL Generic/Rheumatology modules) questionnaires. SLE Disease Activity Index (SLEDAI), Systemic Lupus International Collaborating Clinics/ACR Damage Index (SDI), severity, self-concept and socioeconomic status (SES) were measured. For 24 children, CHAQ scores significantly correlated with SLEDAI (rho = 0.4, p = 0.04), SDI (rho = 0.6, p = 0.004), and associated with severity (p = 0.03). PedsQL scores did not significantly correlate with above parameters. Higher self-concept/SES correlated (p < 0.05) with better physical function and QOL. For 19 parents, the only significant correlation was between SLEDAI and Worry domain-Rheumatology module (rho = 0.5, p = 0.01). Lack of strong correlation of disease activity with QOL and physical function suggests that they are different constructs with partial overlap, and should be considered collectively while evaluating the impact of SLE on children/families. Self-concept and SES should be assessed while measuring QOL in children. Larger sample is required to confirm results.

Social support and physical health: the importance of belonging

Social support is a multifaceted construct recognized as a significant predictor of physical health. In this study, the authors examined several support domains simultaneously in a sample of 247 college students to determine their unique prediction of physical health perceptions and physical symptoms. They also examined gender differences across social support and physical health. Their findings indicated that belonging predicted better health perceptions for women and fewer physical symptoms for men, suggesting that a sense of connection to a group of others is a key support component for the physical health of college students.
