A comparative evaluation of health related quality of life and depression in patients with fibromyalgia syndrome and rheumatoid arthritis

Examining the Role of Structural and Functional Social Network Characteristics in the Context of Chronic Pain: An Ego-centered Network Design

The well-being and functioning of individuals with chronic pain (CP) vary significantly. Social factors, such as social integration, may help explain this differential impact. Specifically, structural (network size, density) as well as functional (perceived social support, conflict) social network characteristics may play a role. However, it is not yet clear whether and how these variables are associated with each other. Objectives were to examine 1) both social network characteristics in individuals with primary and secondary CP, 2) the association between structural network characteristics and mental distress and functioning/participation in daily life, and 3) whether the network's functionality mediated the association between structural network characteristics and mental distress, respectively, functioning/participation in daily life. Using an online ego-centered social network tool, cross-sectional data were collected from 303 individuals with CP (81.85% women). No significant differences between individuals with fibromyalgia versus secondary CP were found regarding network size and density. In contrast, ANCOVA models showed lower levels of perceived social support and higher levels of conflict in primary (vs secondary) CP. Structural equation models showed that 1) larger network size indirectly predicted lower mental distress via lower levels of conflict; 2) higher network density increased mental distress via the increase of conflict levels. Network size or density did not (in)directly predict functioning/participation in daily life. The findings highlight that the role of conflict, in addition to support, should not be underestimated as a mediator for mental well-being. Research on explanatory mechanisms for associations between the network's structure, functionality, and well-being is warranted. PERSPECTIVE: This paper presents results on associations between structural (network size, density) and functional (social support, conflict) social network characteristics and well-being in the context of CP by making use of an ego-centered network design. Results suggest an indirect association between structural network characteristics and individuals with CP their mental well-being.

Perceived Injustice and Anger in Fibromyalgia With and Without Comorbid Mental Health Conditions: A Hebrew Validation of the Injustice Experience Questionnaire

OBJECTIVES

Perceived injustice (PI), assessed by the Injustice Experience Questionnaire (IEQ), is an important trigger of anger. Both PI and anger are associated with adverse chronic pain outcomes, and with comorbid mental health severity. We aimed examined the roles of PI and anger in mediating pain across Fibromyalgia patients, with and without comorbid anxiety/depression (FM+A/D, FM-A/D, respectively), as well as rheumatoid arthritis (RA), and pain-free controls (PFC). We hypothesized the highest levels of PI, anger, and pain in FM+A/D patients, followed by FM-A/D, RA, and PFC, thus also validating a Hebrew version of the IEQ.

METHODS

We translated the IEQ using the forward-backward method and collected data online. Based on self-reported anxiety/depression, the sample comprised 66 FM+A/D patients, 64 FM-A/D, 34 RA, and 32 PFCs. Assessments included the IEQ, state and trait anger, pain intensity, anxiety, depression, and pain catastrophizing. The structure and reliability of the Hebrew IEQ were examined using factor analysis and Cronbach alpha. Bootstrapped-based modeling was used to test the roles of state and trait anger in mediating and moderating the relationship between PI and pain intensity.

RESULTS

We confirmed a one-factor structure of the IEQ, with excellent reliability. FM+A/D patients demonstrated the highest scores in all measures. Within this group, trait anger moderated the mediating effect of state anger in the relationship between PI and pain intensity.

DISCUSSION

Our findings validate a Hebrew IEQ and highlight the importance of PI and state and trait anger in the differential manifestation of mental health comorbidity in FM.

[Cross-sectional study on quality of life and disease activity of rheumatoid arthritis patients]

OBJECTIVE

To analyze health related quality of life (HR-QoL) and physical function of outpatient department patients with rheumatoid arthritis (RA), and to analyze disease activity influence in HR-QoL and functional capacity as well as the divergences between different disease activity standards.

METHODS

The demographic and clinical data of 207 RA cases from Department of Rheumatology and Immunology, Peking University Third Hospital from Jan 2021 to Jul 2021 were collected. RA-specific quality of life (RA-QoL) and the medical outcome 36-item short form health survey (SF-36)were collected to estimate the quality of life. The t test was used for the quantitative data in accordance with normal distribution.

RESULTS

A total of 207 cases were included, with RA-QoL score of 7.8±7.1, physical component summary (PCS) score of 63.8±23.8, and mental component summary (MCS) score of 71.7±21.0. According to disease activity score 28-erythrocyte sedimentation rate (DAS28-ESR), there were 119 patients (59.5%) with remission and low disease activity, and 125 patients (62.5%) with simplified disease activity index (SDAI). The HR-QoL of the patients with remission or low disease activity was significantly better than that of the patients with moderate or high disease activity. The physical function (76.7±17.2 vs. 86.4±15.0, t=2.855, P < 0.01), bodily pain (67.8±8.5 vs. 77.7±15.6, t=4.277, P < 0.01) and health transition (52.8±22.3 vs. 63.9±24.1, t=2.134, P < 0.05) in the low disease activity (LDA) group were lower than those in the complete remission (REM) group according to DAS28-ESR. Other domains of SF-36 and RA-QoL had no differences between these two groups. PCS in the LDA group was lower than that in the REM group (68.3±15.2 vs. 77.3±15.2, t=2.716, P < 0.01), but MCS was not different between the two groups. Determined by SDAI, the RA-QoL score in the LDA group was significantly higher than that in the REM group (9.4±7.1 vs. 6.0±4.8, t=-2.260, P < 0.05), the various dimensions of physical function in the SF-36 score and the PCS score (69.9±16.4 vs. 81.4±15.1, t=3.879, P < 0.05) were lower than that in the REM group, and the MCS score was lower than that in the REM group (67.9±19.3 vs. 74.5±18.8, t=2.721, P < 0.01).

CONCLUSION

The RA-QoL and SF-36 scores of RA patients in outpatient clinics were better, and the MCS was higher than the PCS. Treat-to-target is essential to improve HR-QoL. SDAI can better indicate the HR-QoL of each domain in REM and LDA RA patients.

Quality of life in patients with fibromyalgia: Contributions of disease symptoms, lifestyle and multi-medication

Fibromyalgia (FM) is a disease characterized by the presence of chronic and widespread musculoskeletal pain, which causes a high negative impact on the quality of life (QoL). Although there are many studies about the QoL of patients with FM, it is unknown which variables have a main influence on it. Therefore, in the present study, we aimed to determine which FM symptoms predict a worse QoL and also to establish whether lifestyle and multi-medication are associated to QoL. We assessed a sample of 134 women with FM using a semi-structured clinical interview to explore lifestyle (diet, exercise, smoking) and medication use, and questionnaires to cover the main symptoms of this disease and QoL (SF-36). We found that the patients with FM had a poor QoL, being “physical pain” and “vitality” the most affected domains. A linear regression analysis showed that depression and anxiety assessed by HADS were the FM symptoms which most significantly predicted QoL, explaining 49% of the variance. Concerning lifestyle/medication influences, we found that multiple drug treatment and smoking also predicted a worse QoL (14%). Moreover, patients who practiced exercise regularly showed better QoL than patients who did not (regardless of the severity of FM). Thus, our results suggest that treatment strategies to improve QoL in FM should be focused on improving psychological distress, promoting regular exercise and reducing smoking and multi-medication. The data highlights the role of positive self-management practices to improve QoL in FM.

Life among Chinese fibromyalgia patients: a cross-sectional study

OBJECTIVE

This study is to examine the impact of age on the clinical characteristics, fibromyalgia-related symptom severity and quality of life (QOL) among Chinese fibromyalgia patients.

METHODS

A packet of questionnaires on demographics, medical history, and severity of six major symptoms of fibromyalgia (i.e., pain, fatigue, sleep quality, depression, stress, and QOL) was completed by 124 Chinese patients. The patients were stratified into three groups by age (32 (25.8%) "young" patients, ≤ 39 years; 73 (58.9%) "middle-age" patients, 40-59 years; and 19 (15.3%) "older" patients, ≥ 60 years). Analysis of covariance was conducted and adjusted for body mass index and symptom fibromyalgia duration.

RESULTS

The majority of patients in this study were women (107, 86.3%), and the mean age was 49.4 years (SD 10.8 years). Pairwise comparisons among the three age groups found that the young and middle-aged patients were significantly more troubled than the older patients by their symptoms in several categories: morning tiredness (P ≤ 0.012), depression (P ≤ 0.002), anxiety (P ≤ 0.004), mental health index (P ≤ 0.002), and mental component summary score (P ≤ 0.017). The middle-aged patients reported more trouble than the older patients with regard to social functioning (P = 0.008), emotional roles (P = 0.012), depression (P = 0.012), and sleep quality (P = 0.017). The young patients exhibited the highest levels of current experienced stress (young vs. old, P = 0.013).

CONCLUSION

This study has identified that middle-aged Chinese fibromyalgia patients exhibited less compromise of their QOL than did their older peers. This discrepancy begs a logical explanation and deserves further study. Key Points • This is the first clinical study to show the potential effect of age on fibromyalgia patients in China. • Characteristics, symptom severity, and QOL differ in different age groups. • The younger patients are, the worse their quality of life.

Exploring the Relationship between Fibromyalgia-Related Fatigue, Physical Activity, and Quality of Life

The symptoms of fibromyalgia are varied, including general muscle pain and pain at specific points (also called tender points), excessive fatigue, anxiety, depression, and some psychological problems that can have a negative impact on quality of life. Physical activity is a widely used option by health professionals to alleviate the effects of this syndrome. However, there is no clear information on the possible mediating role of physical activity in the relationship between fibromyalgia-related fatigue and quality of life. Therefore, this study aims to evaluate the relationship between fibromyalgia-related fatigue and quality of life, and to investigate the mediating role of physical activity in patients with this syndrome. Methods: In a cross-sectional study, 237 Portuguese women aged 28 to 75 years (M = 49.12; SD ± 8.87) and 117 Brazilian women aged 20 to 69 years (M = 46.72; SD ± 8.38) were recruited to participate in this study. These patients completed three valid and reliable questionnaires related to the assessment of fibromyalgia-related fatigue (MDF-Fibro-17), physical activity (IPAQ), and quality of life (SF-36). Results: Both samples had scores above the midpoint for all dimensions of fibromyalgia-related fatigue and scores below the midpoint for quality of life. Physical activity had no mediating effect in either sample, as the total indirect effect was not significant. Conclusions: Physical activity does not mediate the relationship between fatigue and quality of life. However, the results also show that the fatigue dimensions associated with fibromyalgia had a negative and significant association with physical and mental health indicators in both samples. Thus, patients with FM with higher scores on fatigue-related symptoms might suffer more from physical and mental health, both of which are related to quality of life.

Predictors of Quality of Life in Patients With Rheumatoid Arthritis in Pakistan: A Cross-Sectional Study

Introduction Rheumatoid arthritis (RA) is a chronic, progressive inflammatory illness that primarily affects peripheral joints and belongs to systemic connective tissue diseases. Rheumatoid arthritis can cause varied and significant impacts on patients' health, including mental and physical wellbeing. The aim of this study is to analyze the factors affecting the quality of life of rheumatoid arthritis patients. Methodology A cross-sectional study was conducted in the outpatient orthopedics department of Indus Hospital and Health Network. The survey questionnaire was used to collect data from participants. The study's 36-item short-form survey (SF-36) questionnaire was used to assess the quality of life (QoL) among RA patients. Linear regression was used to assess the factors associated with the mental and physical components of QoL. Results A total of 154 patients were interviewed in this study. The mean age of participants was 48.96 (±51.35). Factors that contributed to the physical component of QoL included severity of disease, income, age, comorbidity, and anxiety while factors affecting the mental component of QoL included quality of sleep, anxiety, education, comorbidity, and disease severity. Conclusion Healthcare professionals need to work closely with patients to increase their capabilities of being more independent and controlling all the factors that can affect their QoL.

Multiple Factors Affecting Health-Related Quality of Life in Women With Chronic Multisite Musculoskeletal Pain: A Cross-Sectional Study in Ankara, Turkey

Although chronic multi-site musculoskeletal pain is known to cause decreased physical function and impair work and social life, there is insufficient research about its impact on health-related quality of life (HRQoL) in women. The aim of this study was to investigate multiple factors affecting HRQoL in women with chronic multi-site musculoskeletal pain. This study included 227 women with two or more musculoskeletal areas which were painful during the last 3 months. The HRQoL and musculoskeletal system symptoms were evaluated with the Nottingham Health Profile (NHP) and the Nordic Musculoskeletal Questionnaire (NMQ), respectively. Physical activity level, social functionality and depressive symptoms were assessed with the International Physical Activity Questionnaire-Short Form (IPAQ- SF), Social Functioning Scale (SFS) and Beck Depression Inventory (BDI), respectively. Significant predictors for the total score on the NHP were found to be the number of children (p < 0.001), social engagement/withdrawal scale (p:0.094), the number of regions with musculoskeletal pain during the last year (p:0.002) and last 7 days (p:0.036), depressive symptoms (p < 0.001), current employment status (p:0.084), and the presence of chronic disease (p < 0.001). The results of this study demonstrated that both sociodemographic characteristics, and social and psychological factors may affect the HRQoL in women with chronic multi-site musculoskeletal pain.

Well-being and Perceived Stigma in Individuals With Rheumatoid Arthritis and Fibromyalgia: A Daily Diary Study

INTRODUCTION

The presence or absence of clearly defined symptoms and underlying pathophysiology may be a crucial variable related to variability in well-being and stigmatization in individuals with chronic pain (ICPs). In the context of pain, absence of clearly defined symptoms and pathophysiology deviates from the widely endorsed biomedical model and as such, may lead to stigmatization, which in turn could be related to ICPs' well-being.

OBJECTIVES

The present study compared physical, psychological, social well-being, and perceived stigmatization in individuals with clearly defined symptoms and underlying pathophysiology (rheumatoid arthritis, RA) and individuals with less well understood symptoms and pathophysiology (fibromyalgia, FM) using daily diaries. Furthermore, the association between daily perceived stigmatization and daily well-being was examined.

MATERIALS AND METHODS

Seventy-nine participants with FM, 86 participants with RA, and 33 participants with both diagnoses completed a diary for 14 consecutive days.

RESULTS

Compared to individuals with RA, individuals with FM and individuals with both diagnoses reported worse daily well-being. After controlling for age, pain duration, and daily pain, differences between FM and RA remained significant for social well-being and completion of plans. Differences between RA and the dual diagnosis group remained significant for completion of plans, negative affect, and isolation. Furthermore, results suggested more stigmatization in individuals with FM than in individuals with RA. Individuals with both diagnoses reported equal stigmatization as individuals with FM, but more stigmatization than individuals with RA. Finally, increased levels of perceived stigma were associated with lower well-being.

DISCUSSION

Findings highlight that the absence of clearly defined symptoms and pathophysiology could be contributing to greater feelings of stigmatization, which may be detrimental for ICPs' well-being.

Depressive Symptoms and Quality of Life in a Sample of Italian Women with a Diagnosis of Fibromyalgia: The Role of Attachment Styles

BACKGROUND

Women with fibromyalgia (FM) commonly suffer from depression, pervasive fatigue, and pain. The attachment style has been hypothesized to be an important factor for understanding the experience of these symptoms. Therefore, the present cross-sectional study is aimed at investigating the effect of attachment styles in women with a diagnosis of FM on depressive symptoms and quality of life.

METHOD

Participants were 453 Italian women with a physician's diagnosis of FM with a mean age of 47 years (SD = 10.9). To assess attachment styles, quality of life, and depressive symptoms, women responded, respectively, to the Relationship Questionnaire, the World Health Organization Quality of Life Questionnaire, and the Beck Depression Inventory II.

RESULTS

Our results showed that the incidence of depressive symptoms was elevated, with 59% of women reporting moderate to severe symptoms. Also, the statistical analyses showed that both preoccupied and avoidant/dismissing attachments were related with depression symptoms and low perception of QoL.

CONCLUSIONS

Our study demonstrates that, when evaluating the impact of FM on the QoL of women, it is important to consider the complexity of the variables that are at play. Insecure attachment styles and depressive symptoms seem to increase the likelihood of the psycho-social-somatic malaise in FM women.

The Clinical Use of Curcumin for the Treatment of Rheumatoid Arthritis: A Systematic Review of Clinical Trials

Rheumatoid arthritis (RA) is a chronic inflammatory disease of the joints, which is prevalent in about 0.5-1.0% of the world population. Newer therapies for RA have only minimal efficacy in some cases and some adverse effects. Curcumin with anti-antioxidant, anti-inflammatory, and immunomodulatory properties might have beneficial effects on RA. We have carried out a systematic review with the main aim of estimating the effect of curcumin supplementation on RA. A systematic search of the medical databases, PubMed, Scopus, ISI, and Google Scholar was performed up to March 21, 2020 to identify clinical trials assessing the effect of turmeric or curcumin on RA. Six studies, comprising 259 patients with RA of 6-12 weeks duration, were included. Disease activity was assessed using 28 joints (DAS-28), visual analog scale (VAS), and American College of Rheumatology (ACR-20) scores. Treatment with curcumin significantly reduced DAS-28 scores in four out of five studies and VAS scores for pain in all three studies and significantly increased ACR-20 scores in all three studies in which it was measured. Erythrocyte sedimentation rate (ESR) and circulating C-reactive protein (CRP) were assessed in six and five studies, respectively, out of which four studies reported significant reductions in these parameters in response to curcumin treatment. Rheumatoid factor (RF) was significantly reduced after consumption of curcumin in all three relevant studies. None of the studies reported serious adverse effects with curcumin consumption. The present systematic review suggests that curcumin could be used as a safe agent to treat RA. Thus, further validation is justified.

Clinical, psychological and quality of life differences in fibromyalgia patients from secondary and tertiary healthcare

BACKGROUND

The 'funnel effect' of Fibromyalgia (FM) assumes that as patients access healthcare services, they present greater severity and a more complex clinical situation than individuals with FM from the general population, but the studies comparing patients treated in different levels of healthcare are scarce. The aim of this study was to analyse the 'funnel effect' hypothesis by comparing patients from secondary and tertiary healthcare services.

METHODS

A cross-sectional sample of female patients was selected in secondary (rheumatology practices - RP) and in tertiary healthcare (chronic pain clinics - CPC). Information about sociodemographic, clinical and psychological characteristics was collected and health related quality of life (HRQL) was assessed.

RESULTS

In total, 55 patients from RP and 60 patients from CPC were included in the comparison. Patients from CPC revealed a worst clinical status (higher number of tender points, medical visits and comorbidity), more somatic symptoms (pain and daytime dysfunction levels) and worst emotional status (more anxiety) than patients from RP. Patients attending CPC also revealed a worst HRQL than RP patients although this difference was mediated by the differences in clinical and psychological variables.

CONCLUSIONS

Our study supports the 'funnel effect' hypothesis among patients of different healthcare levels, with patients from tertiary healthcare services revealing worst clinical status, more somatic and psychological symptoms, and worst HRQL than patients from secondary healthcare services.

SIGNIFICANCE

The worst clinical and psychological status and poorer quality of life in the patients from tertiary healthcare (chronic pain clinics) in relation to the patients from secondary healthcare (rheumatology practices) must be taken into account to design studies that assess any of these aspects, to a proper analysis and interpretation of the data, and to define the scope of its generalization, as data from different clinical settings are not directly comparable.

The Co-Morbidity between Bipolar and Panic Disorder in Fibromyalgia Syndrome

About half of the patients with fibromyalgia (FM) had a lifetime major depression episode and one third had a panic disorder (PD). Because the co-morbidity between bipolar disorder (BD) and PD marks a specific subtype of BD we aimed to investigate if co-morbid BD/PD (comBD/PD) occurs more frequently than the single disorder in FM patients and evaluate the clinical significance and timing of this co-morbidity. Further, we explored the role of co-morbid subthreshold BD and PD. In 118 patients with FM, lifetime threshold and sub-threshold mood disorders and PD were diagnosed with Diagnostic and Statistical Manual of Mental Disorders-IV-Text Revision (DSM-IV-TR) Clinical Interview. Demographic and clinical variables were compared in co-morbid BD/PD (comBD/PD) and not co-morbid BD/PD (nocomBD/PD) subgroups. The co-morbidity BD/PD was seen in 46.6% of FM patients and in 68.6% when patients with minor bipolar (MinBD) and sub-threshold panic were included. These rates are higher than those of the general population and BD outpatients. There were no statistically significant differences between threshold and sub-threshold comBD/PD and nocom-BD/PD subgroups in demographic and clinical parameters. In the majority of patients (78.2%), the onset of comBD/PD preceded or was contemporary with FM. These findings support the hypothesis that comBD/PD is related to the development of FM in a subgroup of patients.

Educational needs of patients with rheumatic and musculoskeletal diseases attending a large health facility in Austria

INTRODUCTION

Patient education is an important part of the management of rheumatic and musculoskeletal diseases. Given that patients with diverse diseases do not have the same needs, it is crucial to assess the educational requirements of targeted groups to provide tailored educational interventions. The aim of our study was to assess educational needs of a large cohort of patients with different rheumatic and musculoskeletal diseases attending a health facility in Austria.

METHODS

We assessed educational needs, via an online survey of patients with fibromyalgia (FMS), rheumatoid arthritis (RA), and ankylosing spondylitis (AS) recruited from an Austrian health-care facility, using the Austrian version of the Educational Needs Assessment Tool (OENAT).

RESULTS

For our sample of 603 patients, AS (62%), RA (15%), and FMS (24%), there were no educational need differences for the domains of movements, disease process, and self-help measures. Patients with FMS had less need for pain management education and greater need for education about feelings, than other disease groups. Patients with RA had a greater need for education related to treatments than other groups, and patients with AS had a greater need for treatment education than patients with FMS. Patients with AS reported greater need for support system education than other patient groups.

CONCLUSION

Educational needs vary by disease groups, suggesting that health-care professionals should assess disease-specific needs for education to provide optimal assistance in disease management for patients.

Adult attachment styles, self-esteem, and quality of life in women with fibromyalgia

Recently, the research on pain-related disability has increasingly paid attention to the psychological and social factors that may influence the biological condition. In the current study, we aimed to explore attachment styles, self-esteem, and quality of life in individuals with a diagnosis of fibromyalgia. Participants were 371 diagnosed women, with a mean age of 42.7 years (standard deviation = 10.6). The average number of years since diagnosis was 7.4 years (standard deviation = 2.4) years. To assess attachment, quality of life, and self-esteem, women responded, respectively, to the Relationship Questionnaire, the World Health Organization Quality of Life Questionnaire, and the Rosenberg Self-Esteem Inventory. Our results showed that secure attachment relationships and high self-esteem represent protective factors for quality of life of women with fibromyalgia, while the contrary emerged for insecure attachments and low self-esteem. The understanding of the psychological components that contribute to fibromyalgia may improve the effectiveness of interventions.

High Levels of Physical Fitness Are Associated With Better Health-Related Quality of Life in Women With Fibromyalgia: The al-Ándalus Project

BACKGROUND

Physical fitness is a marker of health and is associated with health-related quality of life (HRQoL). Identifying which components of physical fitness are associated with HRQoL in people with fibromyalgia may contribute to the development of more specific therapeutic strategies.

OBJECTIVE

The 2 aims of this study were to examine the association of different components of physical fitness (ie, flexibility, muscle strength, speed and agility, and cardiorespiratory fitness) with HRQoL and to determine the extent to which any association between the components of physical fitness and HRQoL were of clinical relevance to women with fibromyalgia.

DESIGN

A cross-sectional design was used.

METHODS

This study included 466 women with fibromyalgia from southern Spain (Andalusia). The Senior Fitness Test battery and the handgrip test were used to assess physical fitness, and the 36-Item Short-Form Health Survey (SF-36) was used to assess HRQoL. Tender points, cognitive impairment, anthropometric measurements, and medication usage were also measured. First, multivariate linear regression was used to assess the individual relationship of each physical fitness test with the 8 dimensions of the SF-36. Second, a standardized composite score was computed for each component of physical fitness (flexibility, muscle strength, speed and agility, and cardiorespiratory fitness). A 1-way analysis of covariance to assess the differences in each of the 8 dimensions of the SF-36 across each physical fitness composite score was conducted. Forward stepwise regression was performed to analyze which components of physical fitness were independently associated with the SF-36 physical and mental component scales.

RESULTS

Overall, higher levels of physical fitness were associated with higher levels of HRQoL (regardless of the SF-36 subscale evaluated). The effect sizes for HRQoL between participants with the lowest and the highest physical fitness levels ranged from moderate to large (Cohen d = 0.53-0.90). The muscle strength composite score was independently associated with the SF-36 physical component scale, whereas the flexibility composite score and cardiorespiratory fitness were independently associated with the SF-36 mental component scale.

LIMITATIONS

A limitation was that the cross-sectional design precluded the establishment of causality. Additionally, only women were included in the study, because fibromyalgia predominantly affects women.

CONCLUSIONS

High levels of physical fitness were consistently associated with better HRQoL in women with fibromyalgia; clinically relevant differences were demonstrated between those at extreme physical fitness levels. Muscle strength, flexibility, and cardiorespiratory fitness were independent indicators of HRQoL. These results warrant further prospective research on the potential of fitness to predict HRQoL in this population.

A Comparative Study of Fibromyalgia, Rheumatoid Arthritis, Spondyloarthritis, and Sjögren’s Syndrome; Impact of the Disease on Quality of Life, Psychological Adjustment, and Use of Coping Strategies

Background

Fibromyalgia, rheumatoid arthritis, spondyloarthritis, and Sjögren’s syndrome are chronic rheumatic diseases with very different clinical characteristics, but which share symptoms such as pain and fatigue. The aim of the study was to examine the impact of the disease on psychological adaptation in fibromyalgia compared with other rheumatic diseases (rheumatoid arthritis, spondyloarthritis, and Sjögren’s syndrome).

Methods

In a multicenter study, 165 women with rheumatic diseases (48 with fibromyalgia, 47 with rheumatoid arthritis, 47 with spondyloarthritis, 23 with Sjögren’s syndrome) completed the General Health Questionnaire–28 (emotional distress), Fatigue Severity Scale (fatigue), Fibromyalgia Impact Questionnaire (impact of the disease), Coping Strategies Questionnaire (coping), and Mini International Neuropsychiatric Interview (comorbidity with DSM IV axis-I disorders). We used the Kruskal-Wallis test, Mann-Whitney U test, and chi2 test to compare comorbid anxiety and depressive disorders and to compare the impact of the disease on patients’ mental well-being and daily life and adjustment (coping strategies).

Results

Anxiety and depressive disorders were more common in fibromyalgia patients; they had higher scores on impact of the disease, physical symptoms, pain, and fatigue than rheumatoid arthritis patients and reported more fatigue than patients with spondyloarthritis. Overall, they used more maladaptive coping strategies (less use of distancing from pain than patients with rheumatoid arthritis and spondyloarthritis, less use of ignoring pain sensations, and more use of catastrophizing than those with rheumatoid arthritis). No differences were found between fibromyalgia and Sjögren’s syndrome on impact and adjustment.

Conclusions

Compared with other rheumatic diseases, fibromyalgia has a greater impact on daily life; patients have more difficulty adjusting to the disease and generally use poorer strategies to cope with pain.

The mediating and moderating effects of meaning in life on the relationship between depression and quality of life in patients with dysphagia

AIMS AND OBJECTIVES

To identify whether meaning in life has moderating and mediating effects on the relationship between depression and quality of life in patients with dysphagia.

BACKGROUND

Dysphagic patients typically have multidimensional problems, such as depression, which can negatively influence their quality of life. Meaning in life, therefore, can be used as a psychological resource that may enhance quality of life for these patients.

DESIGN

A descriptive cross-sectional research design was used.

METHODS

Ninety patients with dysphagia were recruited for a survey from eight general and rehabilitation hospitals in Korea. The questionnaires, which included the Korean version of the Swallowing Quality of Life scale developed by Cha, the Center for Epidemiological Studies-Depression Scale developed by Radloff, and the Purpose in Life test developed by Crumbaugh and Maholick, were used for data collection. Descriptive statistics, Hayes' PROCESS macro and Cronbach's alpha were used for data analyses.

RESULTS

Meaning in life was found to mediate the relationship between depression and quality of life in patients with dysphagia. However, the index of moderation was not statistically significant, which mean that meaning in life did not moderate the relationship between the patients' depression and quality of life.

CONCLUSIONS

Meaning in life had a mediating effect on the relationship between depression and quality of life in patients with dysphagia. Thus, to improve the quality of life of patients with dysphagia, nurses should apply interventions to help them find meaning in life.

RELEVANCE TO CLINICAL PRACTICE

Meaning in life can be used as a nursing intervention strategy to improve the quality of life for patients living with dysphagia and depression.

Effect of Baseline Characteristics on the Pain Response to Pregabalin in Fibromyalgia Patients with Comorbid Depression

Objective

To evaluate the effect of baseline characteristics on the treatment response to pregabalin in fibromyalgia (FM) patients with depression.

Design

Post hoc analysis from a randomized, double-blind, placebo-controlled, two-way crossover study of pregabalin (300 or 450 mg/day, twice daily).

Subjects

A total of 193 FM patients taking an antidepressant for comorbid depression.

Methods

The effect of patient baseline characteristics on the treatment response to pregabalin vs placebo was assessed for the primary efficacy end point (mean pain score on an 11-point numeric rating scale). Variables were analyzed using a linear mixed effects model with sequence, period, and treatment as fixed factors, and subject within sequence and within subject error as random factors.

Results

Pregabalin significantly improved mean pain scores vs placebo irrespective of age, duration of FM, number of prior FM medications, depression diagnosis, shorter-term depression (<10 years), prior or no prior opioid use, pain severity, anxiety severity, and sleep disruption severity (all P < 0.05). Compared with placebo, pregabalin did not significantly affect mean pain scores in patients with comorbid insomnia, irritable bowel syndrome, or gastroesophageal reflux disease; severe FM; a diagnosis of depression before FM, longer-term depression (≥ 10 years), more severe depression, or who were taking a high dose of antidepressant.

Conclusions

Pregabalin significantly improved mean pain scores when compared with placebo for the majority of baseline characteristics assessed in FM patients taking an antidepressant for comorbid depression.

Is arthritis associated with suicidal ideation and quality of life?

Arthritis is not only a chronic disease but also causes physical inactivity. We investigated the association between arthritis and quality of life and psychological problems, as measured by suicidal ideation. We used data from the 2013 Community Health Survey, and 162,598 persons aged 40 years and older were included as study subjects. Our main focus was to investigate association of arthritis with suicidal ideation and quality of life. Multivariate survey logistic regression analysis was used to estimate the odds ratio for suicidal ideation, and multivariate survey linear regression analysis used to identify associations between variables and scores on the EuroQol Visual Analogue Scale(EQ-VAS). 8.30% of male and 13.90% of female experienced suicidal ideation, and 16.17% of and 21.23% of female suffered from arthritis. Individuals with arthritis were more likely to report suicidal ideation and have lower health-related quality of life (HRQOL) scores. Furthermore, higher rates of suicidal ideation and lower HRQOLs were also associated with older age, low income and less education. Arthritis was associated with higher rates of suicidal ideation and lower HRQOL scores. These results should contribute to the development and implementation of polices and management strategies to alleviate suicidal ideation and increase HRQOL scores among arthritis patients.

Influencing Factors on Health-Related Quality of Life in Middle-Aged Adults With Hypertension

This article aims to examine the influencing factors on health-related quality of life (HRQOL) in middle-aged adults with hypertension. HRQOL was assessed using EQ-5D from 263 middle-aged adults (40-60 years) with hypertension who participated in the 6th Korean National Health and Nutrition Examination Survey (2014). There were statistically significant differences in health-related quality of life according to income, education, subjective health status, experience of discomfort, activity limitation, stress, and aerobic physical activity. Factors influencing on health-related quality of life in middle-aged adults with hypertension were subjective health status, experience of discomfort, activity limitation, depression, and stress, which explained about 50% of total variance. These factors should be included in the nursing intervention, and psychological aspects such as depression should be emphasized.

Diagnosing fibromyalgia in rheumatoid arthritis: The importance of assessing disease activity

Objectives

This study aims to evaluate fibromyalgia syndrome (FMS) incidence based on 2010 American College of Rheumatology (ACR) criteria in rheumatoid arthritis (RA) patients and the association between FMS with disease activity, functional status and quality of life (QoL).

Patients and methods

The study included 151 RA patients (32 males, 119 females; mean age 52.4±12.7 years; range 21 to 82 years) and 77 controls (13 males, 64 females; mean age 53.7±10.2 years; range 33 to 73 years). Individuals were classified into four groups based on presence of RA and FMS. Group 1 included patients with both RA and FMS (n=53), group 2 included patients with RA and without FMS (n=98), group 3 included controls with FMS (n=15), and group 4 included controls without FMS (n=62). Demographic characteristics, morning stiffness (MS), pain, Disease Activity Score 28 (DAS28), functional and QoL scores were compared among the groups.

Results

No significant differences were found between the four groups as regards the mean age and gender distribution (p>0.05). Higher pain, MS, DAS28, and QoL scores in the groups with FMS drew attention. While FMS was found in 8.1% of RA patients with remission, it was found in 53.9% of patients with active RA, and in 19.5% of controls.

Conclusion

Although FMS incidence in patients with RA was higher compared to controls without inflammatory disease, FMS evaluated with 2010 ACR diagnostic criteria was found to be common in the general population. DAS28 and inflammatory markers were higher in RA patients with FMS; thus, it has been concluded that sleep disorder and widespread pain caused by active disease may facilitate the diagnosis of FMS.

Effects of whole body vibration therapy in pain, function and depression of the patients with fibromyalgia

AIM

Aim of the study is to search the effects of whole body vibration (WBV) in fibromyalgia patients.

MATERIALS AND METHODS

In this single blind study 20 fibromyalgia patients were diagnosed according to 2010 American College of Rheumatology criteria whom participated in the study with the mean age of 57 ± 7 (years). Participants were randomized into 2 equal groups. In the intervention group (n = 10), 6 different types of exercises were combined with 30 hz frequency, 2 mm amplitude WBV for 4 weeks, The control group (n = 10) performed the same exercises on the same platform without vibration. The patients were assessed at baseline, at the 3rd and 6th months by Visual Analogue Scale (VAS), Fibromyalgia Impact Questionnaire (FIQ) and Beck Depression Inventory (BDI).

RESULTS

Only FIQ score was significantly better in the treatment group at the 6th month evaluation (p = 0.043).

CONCLUSION

WBV is found to be effective in reducing symptoms of fibromyalgia.

Determinants of quality of life in patients with fibromyalgia: A structural equation modeling approach

Objective

Health-related quality of life (HRQOL) in patients with fibromyalgia (FM) is lower than in patients with other chronic diseases and the general population. Although various factors affect HRQOL, no study has examined a structural equation model of HRQOL as an outcome variable in FM patients. The present study assessed relationships among physical function, social factors, psychological factors, and HRQOL, and the effects of these variables on HRQOL in a hypothesized model using structural equation modeling (SEM).

Methods

HRQOL was measured using SF-36, and the Fibromyalgia Impact Questionnaire (FIQ) was used to assess physical dysfunction. Social and psychological statuses were assessed using the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), the Arthritis Self-Efficacy Scale (ASES), and the Social Support Scale. SEM analysis was used to test the structural relationships of the model using the AMOS software.

Results

Of the 336 patients, 301 (89.6%) were women with an average age of 47.9±10.9 years. The SEM results supported the hypothesized structural model (χ² = 2.336, df = 3, p = 0.506). The final model showed that Physical Component Summary (PCS) was directly related to self-efficacy and inversely related to FIQ, and that Mental Component Summary (MCS) was inversely related to FIQ, BDI, and STAI.

Conclusions

In our model of FM patients, HRQOL was affected by physical, social, and psychological variables. In these patients, higher levels of physical function and self-efficacy can improve the PCS of HRQOL, while physical function, depression, and anxiety negatively affect the MCS of HRQOL.

[Effect and Path Analysis of Laughter Therapy on Serotonin, Depression and Quality of Life in Middle-aged Women]

PURPOSE

This study was done to examine how laughter therapy impacts serotonin levels, QOL and depression in middle-aged women and to perform a path analysis for verification of the effects.

METHODS

A quasi-experimental study employing a nonequivalent control group and pre-post design was conducted. Participants were 64 middle-aged women (control=14 and experimental=50 in 3 groups according to level of depression). The intervention was conducted five times a week for a period of 2 weeks and the data analysis was conducted using repeated measures ANOVA, ANCOVA and LISREL.

RESULTS

Results showed that pre serotonin and QOL in women with severe depression were the lowest. Serotonin in the experimental groups increased after the 10th intervention (p=.006) and the rise was the highest in the group with severe depression (p=.001). Depression in all groups decreased after the 5th intervention (p=.022) and the biggest decline was observed in group with severe depression (p=.007). QOL of the moderate and severe groups increased after the 10th intervention (p=.049), and the increase rate was highest in group with severe depression (p<.006). Path analysis revealed that laughter therapy did not directly affect depression, but its effect was indirectly meditated through serotonin variation (p<.001).

CONCLUSION

Results indicate that serotonin activation through laughter therapy can help middle-aged women by lessening depression and providing important grounds for depression control.

Humanistic and economic burden of fibromyalgia in Japan

Purpose

The aim of this study was to examine the health and economic burden associated with fibromyalgia among adults in Japan.

Materials and methods

Data from the 2011–2014 Japan National Health and Wellness Survey (n=115,271), a nationally representative survey of adults, were analyzed. The greedy matching algorithm was used to match the respondents who self-reported a diagnosis of fibromyalgia with those not having fibromyalgia (n=256). Generalized linear models, controlling for covariates (eg, age and sex), examined whether the respondents with fibromyalgia differed from matched controls based on health status (health utilities; Mental and Physical Component Summary scores from Medical Outcomes Study: 12-item Version 2 and 36-item Version 2 Short Form Survey), sleep quality (ie, sleep difficulty symptoms), work productivity (Work Productivity and Activity Impairment Questionnaire – General Health Version 2.0), health care resource use, and estimated annual indirect and direct costs (based on published annual wages and resource use events) in Japanese yen (¥).

Results

After adjustment for covariates, respondents with fibromyalgia relative to matched controls scored significantly lower on health utilities (adjusted means =0.547 vs 0.732), Mental Component Summary score (33.15 vs 45.88), and Physical Component Summary score (39.22 vs 50.81), all with P<0.001; these differences exceeded the clinically meaningful levels. In addition, those with fibromyalgia reported significantly poorer sleep quality than those without fibromyalgia. Respondents with fibromyalgia compared with those without fibromyalgia experienced significantly more loss in work productivity and health care resource use, resulting in those with fibromyalgia incurring indirect costs that were more than twice as high (adjusted means =¥2,826,395 vs ¥1,201,547) and direct costs that were nearly six times as high (¥1,941,118 vs ¥335,140), both with P<0.001.

Conclusion

Japanese adults with fibromyalgia experienced significantly poorer health-related quality of life and greater loss in work productivity and health care use than those without fibromyalgia, resulting in significantly higher costs. Improving the rates of diagnosis and treatment for this chronic pain condition may be helpful in addressing this considerable humanistic and economic burden.

Evaluation of coping strategies in established rheumatoid arthritis patients: emergence of concealment in an Asian cohort

AIM

To evaluate coping strategies of Asian RA patients and their associations with health-related quality of life (HRQoL).

METHODS

A cross-sectional sample of patients with established RA was evaluated using measures of coping (Coping in Rheumatoid Arthritis Questionnaire [C-RAQ]; appraisal of coping effectiveness and helplessness), HRQoL (Mental and Physical Components [MCS/PCS] of the Short Form 12v2; Rheumatoid Arthritis Impact of Disease score [RAID]) and clinical/laboratory assessments. Principal component analysis was conducted to identify coping strategies. Multiple linear regression analyses were performed to evaluate the associations between coping strategies and HRQoL outcomes.

RESULTS

The study sample comprised 101 patients, 81% female, 72.3% Chinese, mean age 54.2 ± 12.6 years. Five coping strategies were identified: Active problem solving (E = 5.36), Distancing (E = 2.30), Concealment (E = 1.89), Cognitive reframing (E = 1.55) and Emotional expression (E = 1.26). Concealment was consistently associated with PCS (r_s = -0.23, P = 0.049), MCS (r_s = -0.24, P = 0.04) and RAID (r_s = 0.39, P < 0.001), and was significant in the multivariate model to explain lower disease-specific HRQoL (RAID) even after adjusting for disease activity, coping effectiveness and helplessness (β = 0.20, P = 0.04). Emotional expression was associated with poorer physical HRQoL (PCS), after adjusting for disease severity, body mass index, coping effectiveness, helplessness and Concealment (β = -0.39, P < 0.001). Perceived coping-related helplessness was significant in multivariate correlates for PCS (β = -0.25, P = 0.036), MCS (β = -0.29, P = 0.02) and RAID (β = 0.53, P < 0.001), after adjusting for covariates.

CONCLUSION

Concealment and Emotional expression are associated with lower disease-specific HRQoL and physical HRQoL respectively, with the former coping strategy likely to be culture-specific. Interventions should tailor psychosocial support needs to address not only coping strategies, but patients' perception of their coping.

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.

Effectiveness of Three Types of Interventions in Patients with Fibromyalgia in a Region of Southern Catalonia

Several pharmacological and nonpharmacological treatments can be used to alleviate the symptoms of fibromyalgia, although none of them are completely effective at present. In this study, we analyzed the effectiveness of different therapies in three groups of people diagnosed with fibromyalgia. The sample for this randomized controlled trial was made up of 66 people diagnosed with fibromyalgia in southern Catalonia. In turn, this sample was divided into three groups of 22 participants each, who were treated with: i) cervical infiltration with botulinum toxin, ii) group problem-solving therapy, or iii) both therapies. The variables recorded were quality of life, suicidal thoughts, perception of pain, quality of sleep, and satisfaction. Female patients composed 96.9% (n = 64) of the study sample. Satisfaction with the infiltration was 5.1 ± 2.7 points, while in group problem-solving therapy it was 6.6 ± 3.2. Self-perceived health in the infiltration group (p = .016) and the therapy group (p = .001) improved after the intervention took place. The risk of suicide decreased in the both treatments/groups (p = .049). Pain was reduced by 31.8% with infiltration, 13.6% with therapy, and 22.7% with both treatments. Anxiety/depression decreased by 45% with therapy, 36.3% with infiltration, and 36.3% with both treatments. The results also showed that the use of both treatments significantly reduces suicidal thoughts (p = .049). In conclusion, this study showed the complexity of reducing chronic pain and increasing the quality of life of people with fibromyalgia.

[Characterization of the pain, sleep and alexithymia patterns of patients with fibromyalgia treated in a Brazilian tertiary center]

OBJECTIVES

Fibromyalgia (FM) is a complex syndrome that is characterized by lasting and diffuse chronic musculoskeletal pain, derived from non-inflammatory causes and classically associated with the presence of specific tender points. However, studies have highlighted other important symptoms associated with a lower quality of life (QOL) in FM, such as sleep disturbances and alexithymia. This study aimed to investigate the pain, sleep and alexithymia patterns of FM patients treated in a Brazilian tertiary center.

METHODS

20 patients with FM who were followed-up in the Rheumatology outpatient clinic of a Brazilian tertiary center (Faculdade de Medicina de São José do Rio Preto - FAMERP, São Paulo, Brazil) and 20 patients without FM from other outpatient services of the FAMERP completed a clinical and socio-demographic questionnaire, the Fibromyalgia Impact Questionnaire (FIQ), the Pittsburgh Sleep Quality Index (PSQI), the Toronto Alexithymia Scale (TAS-20) and the SF-36 (WHOQOL).

RESULTS

The patients with FM presented worse performances in all QOL dimensions of the SF-36 and higher scores on the PSQI (p=0.01), and the TAS-20 (p=0.02). Patients with FM also scored significantly higher in all specific domains of PSQI and TAS-20.

DISCUSSION

The present data were in accordance with literature, disclosing a worse performance of patients with FM on pain impact, sleep complains and more presence of alexithymia.

CONCLUSION

Studies have disclosed the presence of important and frequently underdiagnosed symptoms beyond pain complaints in FM, such as sleep complaints and alexithymia, and a better knowledge of such disturbances might improve FM patients' approach and treatment.

Living with the unexplained: coping, distress, and depression among women with chronic fatigue syndrome and/or fibromyalgia compared to an autoimmune disorder

Chronic fatigue syndrome (CFS) and fibromyalgia are disabling conditions without objective diagnostic tests, clear-cut treatments, or established etiologies. Those with the disorders are viewed suspiciously, and claims of malingering are common, thus promoting further distress. It was hypothesized in the current study that levels of unsupportive social interactions and the coping styles used among those with CFS/fibromyalgia would be associated with perceived distress and depressive symptoms. Women with CFS/fibromyalgia (n=39), in fact, reported higher depression scores, greater perceived distress and more frequent unsupportive relationships than healthy women (n=55), whereas those with a chronic, but medically accepted illness comprising an autoimmune disorder (lupus erythematosus, multiple sclerosis, rheumatoid arthritis; n=28), displayed intermediate scores. High problem-focused coping was associated with low levels of depression and perceived distress in those with an autoimmune condition. In contrast, although CFS/fibromyalgia was also accompanied by higher depression scores and higher perceived distress, this occurred irrespective of problem-focused coping. It is suggested that because the veracity of ambiguous illnesses is often questioned, this might represent a potent stressor in women with such illnesses, and even coping methods typically thought to be useful in other conditions, are not associated with diminished distress among those with CFS/fibromyalgia.

Relation of age with symptom severity and quality of life in patients with fibromyalgia

OBJECTIVE

To examine the relation of age with symptom severity and quality of life (QOL) in patients with fibromyalgia, and to compare physical and mental health of our female patients with those of the US female general population.

PATIENTS AND METHODS

We studied 978 patients with fibromyalgia from May 1, 2001 through April 30, 2004, and divided them into age groups of young (≤39 years), middle-aged (40-59 years), and older (≥60 years). They completed the Fibromyalgia Impact Questionnaire and the Short Form-36 Health Status Questionnaire (SF-36). Standardized SF-36 physical and mental health summary scores were compared with those of the US female general population of similar age. One-way analysis of variance and post hoc paired t test analyses were performed to detect differences across age groups.

RESULTS

Pairwise comparison found young and middle-aged patients having worse fibromyalgia symptoms in all subscales except the anxiety subscale compared with older patients (P≤.01). Similarly, these young and middle-aged patients had worse QOL in the SF-36 mental component summary, as well as SF-36 general health perceptions, vitality, social functioning, and mental health index, compared with older patients (all P<.001). When the QOL of our female patients was compared with that of the US female general population of similar age with standardized SF-36 scores, all age groups had lower QOL in physical, as well as mental, health, with more reduction in physical health, particularly in young patients.

CONCLUSION

Our study shows that symptom severity and QOL differ across age groups in patients with fibromyalgia, with young and middle-aged patients having poorer QOL and worse fibromyalgia symptoms than do older patients. QOL in physical health was reduced more than in mental health, particularly in young patients, compared with the general population.

Contributions of a group-based exercise program for coping with fibromyalgia: a qualitative study giving voice to female patients

Numerous quantitative studies have illustrated the potential usefulness of exercise programs for women with fibromyalgia. However, a deeper understanding of the physical and especially psychosocial benefits of exercise therapy from the subjective perspective of this population is still needed. This study was conducted with 25 women who had fibromyalgia and were participating in a nine-month, group-based exercise program. The aim was to provide an in-depth description and analysis of the perceived physical and psychosocial benefits of participation. Qualitative data were collected through observation, interviews, and focus groups. The exercise program not only alleviated the physical symptoms of fibromyalgia, but social interactions within the group helped to counteract the isolation, frustration, and depression often associated with this chronic condition. The data from this study may contribute to a deeper understanding of the benefits of exercise for women with fibromyalgia and might be useful for the improvement of future exercise programs for this population.

Validation and psychometric properties of the Spanish version of the Quality of Life Scale (QOLS) in patients with fibromyalgia

Fibromyalgia (FM) is a chronic disease associated with high disability levels, which in turn lead to low quality of life (QOL). The objectives of this study were to translate the Quality of Life Scale (QOLS) into Spanish and to assess its reliability and validity for its use in patients with FM. A total of 140 women are suffering from FM (52.87 ± 9.35 years old). All belonged to an association of FM patients (AFIXA, Jaén, Spain). The Spanish versions of the FM impact questionnaire (FIQ), the SF-36, and Beck's Depression Inventory were used to assess them. The construct's validity was checked by means of exploratory factorial analysis (varimax with Kaiser normalization). Test-retest reliability was assessed through intraclass correlation coefficient (ICC), and convergent validity through Spearman's correlation. Results show that Cronbach's alpha was 0.887, which revealed high internal consistency. The value of ICC for the QOLS total was 0.765 (95 % CI 0.649-0.843, p < 0.001). QOLS presented a significant Spearman's correlation (p < 0.01) with Beck's Inventory, with the physical and mental subtotals of SF-36 and with FIQ. The main component analysis and the varimax rotation revealed the convergence on three factors that account for 54.05 % of variance. Taking into account the severity of the disorder, significant differences (p < 0.05) appeared in QOLS, with moderately afflicted patients getting higher scores than the most severe cases. In conclusion, our study shows that the Spanish version of the QOLS is a reliable instrument, with a good convergent and discriminant construct validity, for measuring the QOL of Spanish FM patients.

Depression treatment patterns among individuals with osteoarthritis: a cross sectional study

BACKGROUND

Arthritis and depression often co-occur; however, studies that describe patterns of depression treatment among individuals with arthritis are scant. The purpose of the study was to examine depression treatment patterns among individuals with osteoarthritis (OA) by predisposing, enabling, need factors, personal health practices and external health environment.

METHODS

Retrospective cross-sectional design was used. Data were obtained from 2008 and 2010 Medical Expenditure Panel Survey (MEPS). The sample consisted of 647adults aged over 21 years with depression and OA. Depression treatment was categorized as: 1) No treatment;2) antidepressant use only and 3) both antidepressants and psychotherapy (combination therapy). Chi- square tests and multinomial logistic regressions were used to describe patterns of depression treatment. All analysis was performed using Statistical Analysis Software (SAS) version 9.3.

RESULTS

Overall, 13.0% of the study sample reported no depression treatment, 67.8% used antidepressants only and 19.2% used combination therapy. Among individuals with OA significant subgroup differences in depression treatment were observed. For example, African Americans were less likely to report depression treatment compared to whites [antidepressants: AOR=0.33, 95% CI=0.21,0.51; combination therapy: AOR=0.39, 95% CI=0.23, 0.65]. Elderly adults were more likely to receive antidepressants and less likely to receive psychotherapy as compared to younger adults [AOR=0.53, 95% CI= 0.28,0.98]. Adults with anxiety were more likely to report depression treatment compared to those without anxiety [antidepressants: AOR=1.53, 95% CI=1.06, 2.22; combination therapy: AOR=3.52, 95% CI=2.40, 5.15].

CONCLUSION

Future research needs to examine the reason for low rates of combination therapy as well as subgroup differences in combination therapy among individuals with OA.

Predictors and effective factors on quality of life among Iranian patients with rheumatoid arthritis

INTRODUCTION

Rheumatoid arthritis is a chronic autoimmune disorder that leads to joint swelling, stiffness, pain and progressive joint destruction. It is a common disease with prevalence of 1% worldwide that affecting all aspects of patients' lives. Therefore, this study was conducted to summarize and provide a clear view of quality of life among the patients in Iran through a literature review.

METHODS

This study was conducted as a literature review over article published between 2000 to 2013, by using data bases comprise of Google scholar, Science Direct, Pubmed, IRANDOC, SID, Medlib, Magiran and by key words: "quality of life", "rheumatoid arthritis", "Iran" and their Persian equivalents. Finally 2065 articles assessed and according to the aim of the study are 11 studies synthesized. Extracted results first were summarized in Extraction Table, and then analyzed manually.

RESULTS

In reviewed articles rheumatoid arthritis patients' quality of life was measured by using five different tools, the most important one of them was SF36 questionnaire. Among eight dimensions of SF36 questionnaire, the highest mean according included articles result was social functioning with average score of 63.4 and the lowest for physical limitation (physical role functioning) with score of 43. Overall, mean of eight dimensions was 52.47. The most important factors affecting quality of life were disease severity and pain, depression, income, educational, occupational status, married status, sign of disease, fatigue, anxiety and disease activity scores.

CONCLUSION

The results of the study showed relatively low quality of life of rheumatoid arthritis patients in Iran. Empowering patients by participating them in service delivery process and decision making can improves quality of life and in this regard health care provider must be focused on patient self-care abilities and reinforcing this factor by training them.

[Health-related quality of life in Korean patients with rheumatoid arthritis: association with pain, disease activity, disability in activities of daily living and depression]

PURPOSE

The purpose of this predictive study was to identify factors affecting health related quality of life (HRQoL) in patients with rheumatoid arthritis (RA).

METHODS

The participants in this study were 131 patients with RA who were recruited from the outpatient clinic of a university hospital in Seoul. Disease activity in rheumatoid arthritis was evaluated by calculating the Disease Activity Score 28. Disability in activities of daily living (ADL) was assessed with the Korean Health Assessment Questionnaire, and depression with The Center for Epidemiologic Studies Depression Scale. HRQoL was evaluated using The Short Form 36 Health Survey. Data were analyzed using descriptive statistics, correlation, and hierarchical multiple regression.

RESULTS

Pain, disability in ADL, disease activity, and depression correlated negatively with physical and mental dimensions of HRQoL. But hierachical multiple regression analysis revealed that disability in ADL and depression were the only variables negatively influencing physical and mental QoL after adjustment for influences of sociodemographic variables.

CONCLUSION

Results of this study suggest that disability in ADL and depression, rather than disease activity and pain have profound effects on HRQoL in patients with RA. Further studies are needed to assess the predictive ability of disease activity and pain on HRQoL in this population.

Comparing common reasons for inpatient and outpatient visits between commercially-insured duloxetine or pregabalin initiators with fibromyalgia

Background

The purpose of this study was to examine the main reasons for inpatient or outpatient visits after initiating duloxetine or pregabalin.

Methods

Commercially insured patients with fibromyalgia and aged 18–64 years who initiated duloxetine or pregabalin in 2006 with 12-month continuous enrollment before and after initiation were identified. Duloxetine and pregabalin cohorts with similar demographics, pre-index clinical and economic characteristics, and pre-index treatment patterns were constructed via propensity scoring stratification. Reasons for inpatient admissions, physician office visits, outpatient hospital visits, emergency room visits, and primary or specialty care visits over the 12 months post-index period were examined and compared. Logistic regression was used to assess the contribution of duloxetine versus pregabalin initiation to the most common reasons for visits, controlling for cross-cohort differences.

Results

Per the study design, the duloxetine (n = 3711) and pregabalin (n = 4111) cohorts had similar demographics (mean age 51 years, 83% female) and health care costs over the 12-month pre-index period. Total health care costs during the 12-month post-index period were significantly lower for duloxetine patients than for pregabalin patients ($19,378 versus $27,045, P < 0.05). Eight of the 10 most common reasons for inpatient admissions and outpatient hospital (physician office, emergency room, primary or specialty care) visits were the same for both groups. Controlling for cross-cohort differences, duloxetine patients were less likely to be hospitalized due to an intervertebral disc disorder or major depressive disorder, to have a physician office visit due to nonspecific backache/other back/neck pain (NB/OB/NP) disorder, or to go to specialty care due to a soft tissue, NB/OP/NP, or intervertebral disc disorder. However, duloxetine patients were more likely to have a primary care visit due to a soft tissue disorder, essential hypertension, or other general symptoms.

Conclusion

Among similar commercially insured patients with fibromyalgia who initiated duloxetine or pregabalin, duloxetine patients had significantly lower health care costs over the 12-month post-index period. The leading reasons for inpatient or outpatient visits were also somewhat different.
