Functional disability and health-related quality of life in South Africans with rheumatoid arthritis and systemic lupus erythematosus

Psychiatric manifestations of systemic lupus erythematosus: A brief review with two case-reports

Neuropsychiatric systemic lupus erythematosus is a severe neurological and psychiatric manifestation following systemic lupus erythematosus. Neuropsychiatric systemic lupus erythematosus is a global concern with limited data on its impact on quality of life in Africa. Furthermore, there is a lack of published research on neuropsychiatric systemic lupus erythematosus in Ethiopia. In this article, we present two case reports of Ethiopian patients with systemic lupus erythematosus and neuropsychiatric systemic lupus erythematosus, highlighting the challenges of diagnosing neuropsychiatric systemic lupus erythematosus worldwide. Although the patients were treated with alternative pharmacological agents based on available medications, interdisciplinary collaboration between psychologists, psychiatrists, neurologists, and internists is necessary to decrease the burden of systemic lupus erythematosus patients with neuropsychiatric manifestations. Overall, symptomatic therapy for neuropsychiatric systemic lupus erythematosus in developing countries is a good approach until future evidence-based pharmacotherapy is developed.

Health-related quality of life in Chinese SLE patients: evidence from 1568 SLE patients and 2610 healthy controls

OBJECTIVE

To investigate the effects of systemic lupus erythematosus (SLE) on health-related quality of life (HRQOL), the relationship between disease activity and HRQOL, and potential factors affecting HRQOL in Chinese SLE patients.

METHODS

This study recruited 1568 patients and 2610 controls to explore the effects of SLE on HRQOL. The association between disease activity and HRQOL, and the influencing factors of HRQOL were determined in 1568 patients. Then, we prospectively followed 1096 patients to explore the association between reduced disease activity and improved HRQOL, and the influencing factors of improved HRQOL. The Short-Form 36 (SF-36) and SLE disease activity index (SLEDAI) were used to evaluate HRQOL and disease activity.

RESULTS

Chinese SLE patients had lower HRQOL than controls in all domains (P < 0.001), especially in role-physical (RP) and role-emotional (RE). Compared with SLE patients from outside China, the HRQOL of Chinese patients appeared to be higher in mental component summary (MCS) but lower in RP and RE. SLEDAI was negatively correlated with HRQOL, which was validated using the results of a follow-up study, where SLEDAI reduction was positively associated with HRQOL improvements (P < 0.05). Furthermore, personality, life nervous and experiences of adverse life events may influence HRQOL and HRQOL improvements.

CONCLUSION

SLE significantly affected the HRQOL of Chinese patients, especially in RP and RE. Disease activity was negatively correlated with HRQOL. We also found for the first time some factors affecting HRQOL, which can be regarded as the basis for improving the HRQOL of SLE patients.

Severe flares are associated with a poorer health-related quality of life (HRQoL) in patients with SLE: data from the Almenara Lupus Cohort

BACKGROUND

Flares in patients with SLE, regardless of their severity, have been associated with damage accrual. However, their impact on health-related quality of life (HRQoL) has not been fully evaluated. In fact, disease activity is only minimally associated with HRQoL.

OBJECTIVE

To determine the association between flares and HRQoL.

METHODS

Patients from the Almenara Lupus Cohort were included. Visits occurring between December 2015 and February 2020 were evaluated. Flares were defined as an increase on the SLE Disease Activity Index 2000 (SLEDAI-2K) of at least 4 points; severe flares were those with a final SLEDAI-2K ≥12 and mild-moderate flares all the others. HRQoL was measured using the LupusQoL. Univariable and multivariable generalised estimating regression equations were performed, adjusting for possible confounders. Confounders were determined at one visit, whereas the outcome was determined on the subsequent visit; flares were determined based on the variation of the SLEDAI-2K between these visits.

RESULTS

Two hundred and seventy-seven patients were included; 256 (92.4%) were female, mean age at diagnosis was 36.0 (SD: 13.3) years and mean disease duration at baseline was 9.1 (SD: 7.1) years. Patients had mean of 4.8 (SD: 1.9) visits and a mean follow-up of 2.7 (1.1) years. Out of 1098 visits, 115 (10.5%) flares were defined, 17 were severe and 98 mild-moderate. After adjustment for possible confounders, only severe flares were associated with a poorer HRQoL in planning, pain, emotional health and fatigue.

CONCLUSIONS

Severe flares, but not mild-moderate, flares are associated with poorer HRQoL.

Prevalence of depressive symptoms in patients with rheumatoid arthritis at a regional hospital in KwaZulu-Natal, South Africa

Background

Depression affects 14.8% – 38.8% of patients with rheumatoid arthritis (RA) in developed countries. The prevalence and risk factors for depression in patients with RA in sub-Saharan Africa is not well established.

Aim

To determine the prevalence of depressive symptoms in patients with RA.

Setting

Public sector regional hospital in South Africa.

Methods

A cross-sectional descriptive study was undertaken with 110 adult RA patients. A structured socio-demographic and clinical questionnaire, the modified health assessment questionnaire (mHAQ), the simplified disease activity index (SDAI) for RA, the patient health questionnaire (PHQ-9), and the Household Food Insecurity Access scale (HFIAS) for nutritional status, were used. Correlates of depressive symptomatology in participants with RA were identified using t-tests and regression analyses.

Results

Most of the participants were women (90.9%), 67% had moderate to severe RA disease on the SDAI score, 92.7% reported functional disability (HAQ score of ≥ 1), and 87.2% reported mild to severe depressive symptoms. Unemployment (p < 0.01), severe food insecurity (p < 0.01) and functional disability (p = 0.02), were significantly associated with the depressive symptoms, but not with disease activity (p = 0.8) or inflammatory markers (p = 0.63). Unemployment (adjusted β = −5.07, p < 0.01) and severe food insecurity (adjusted β = −4.47, p < 0.01) were significantly associated with depressive symptoms, based on the adjusted regression model.

Conclusion

As RA effects functional status, with the impact of the resulting unemployment and food insecurity being associated with depression, affected people should be screened for depression and managed using a multidisciplinary approach, especially considering the role of social determinants in RA patients with depression.

Ability to Participate in Social Activities of Rheumatoid Arthritis Patients Compared with Other Rheumatic Diseases: A Cross-Sectional Observational Study

OBJECTIVES

To compare the ability to participate in social activities among rheumatoid arthritis patients with other rheumatic disease patients and identify potentially implicated factors.

PATIENTS AND METHODS

Between June and November 2019, we consecutively selected patients aged ≥18 years with RA (defined according to ACR/EULAR 2010), SpA (ASAS/EULAR 2010), and SLE (ACR 1997).

MAIN OUTCOME MEASURES

Ability to participate in social roles and activities evaluated using the PROMIS score v2.0 short-form 8a (PROMIS-APS).

SECONDARY OUTCOMES

Participation in social activities according to a series of variables (mobility, depression, satisfaction with social relationships, social isolation, company, emotional support, instrumental support, and support via information). We evaluated the association between the ability to participate in social activities and associated variables using multivariable linear regression analysis.

RESULTS

The study population comprised 50 patients with RA (33.1%), 51 patients (33.8%) with SpA, and 50 patients (33.1%) with SLE. The mean PROMIS-APS scores were similar in the three groups. The multivariable analysis for the whole sample showed that the ability to participate in social activities was inversely associated with depression and directly with social satisfaction, mobility, company, and age. The stratified analysis revealed an inverse association between inflammatory activity and ability to participate in social activities in patients with RA and SpA, but not in those with SLE.

CONCLUSION

All patients with RA, SpA, and SLE had a similar ability to participate in social activities. This was associated with other psychosocial factors (social satisfaction, mobility, company, depression) and clinical factors (age and inflammatory activity).

Relationship between disease activity, organ damage and health-related quality of life in patients with systemic lupus erythematosus: A systemic review and meta-analysis

OBJECTIVES

Systemic lupus erythematosus (SLE) is a common systemic autoimmune disease that may lead to considerable physical, psychological, and socioeconomical burden. In previous studies, inconsistent results were reported for the association of disease activity and organ damage with health-related quality of life (HRQoL). This paper aimed to explore the relationship between disease activity, organ damage, and HRQoL measured by SF-36, EQ-5D, LupusQoL, and LupusPRO and investigate whether the correlation is region-specific.

METHODS

We systematically searched for studies reporting the association between SLE disease activity, organ damage, and HRQoL in MEDLINE, EMBASE, PsycINFO, World of Science, the Cochrane Library, and CINAHL from inception to December 2019. A meta-analysis and region subgroup analysis were performed with a random-effects model to estimate pooled correlation coefficients and heterogeneity.

RESULTS

Forty articles were included representing of 6079 adult SLE patients. The meta-analysis of SF-36 and LupusPRO studies revealed mild to moderate negative correlations between disease activity and domains of these HRQoL measurements (correlation coefficient r ranging from -0.27 to -0.07). Likewise, negative correlations were found between organ damage and domains of SF-36 and LupusPRO (r ranging from -0.25 to -0.08). The pooled correlation coefficient is relatively higher in physical functioning related domains than mental health. In the region subgroup analysis, disease activity had strong negative correlations with SF-36 domains in African and European SLE patients, while organ damage had the strongest negative correlation with SF-36 domains in Asian SLE patients (p < 0.010).

CONCLUSION

This study provides the first comprehensive assessment of the relationship between disease activity, organ damage, and four popular HRQoL instruments, which provides useful insight into the target therapy in SLE management.

The impact of SLE on health-related quality of life assessed with SF-36: a systemic review and meta-analysis

OBJECTIVE

To evaluate the impact of systemic lupus erythematosus (SLE) on health-related quality of life (HRQoL) assessed with SF-36 and explore factors associated with HRQoL in SLE patients.

METHODS

A random-effect meta-analysis was performed to calculate extracted data. Sensitivity and subgroup analyses were performed to distinguish sources of heterogeneity.

RESULTS

A total of 36 articles were finally included in this meta-analysis, including 6510 patients. The pooled mean scores of SF-36 physical component summary and mental component summary were 46.10 (95% confidence interval (CI): 43.09-49.10) and 50.37 (95% CI: 47.78-52.87), respectively. Spearman's correlation analysis found that mean age, proportion of female participants, and publication decades were negatively associated with some of the SF-36 domains. Sample size and SLEDAI were positively associated with some of the SF-36 domains. Patients with SLE have lower HRQoL in comparison to the general population.

CONCLUSIONS

SLE has a significant impact on HRQoL, which proves that the necessity of improving HRQoL in SLE patients cannot be ignored. Measuring HRQoL should be considered as an indispensable part of the overall evaluation of health conditions of SLE patients.

Living with systemic lupus erythematosus in South Africa: a bitter pill to swallow

Background

Systemic lupus erythematosus (SLE) often has a profound negative impact on health-related quality of life (HRQoL). In the absence of any qualitative studies in sub-Saharan Africa, we undertook a study to explore living experiences, perceptions and unmet needs of South African patients with SLE.

Methods

Twenty-five women with SLE consented to participate in the study. They underwent individual in-depth interviews exploring their physical concerns, emotional health, sexual well-being and fertility. NVivo software was used for analysis.

Results

Participants were either of black ancestry or mixed racial ancestry, mainly indigent with only a quarter gainfully employed. Living with pain was the most common complaint, negatively impacting on activities of daily living (ADL), family expectations, social life, sleep and intimacy. Most participants expressed challenges of living with fatigue, and many felt their fatigue was misconstrued as being ‘simply lazy’. This pernicious fatigue had negative consequences on many facets of ADL, including caring for dependants, job sustainability and sexual well-being. All participants experienced low emotional states, often associated with suicidal ideations. Many experienced difficulties with fertility and childbearing and these were exacerbated in many instances by the pessimism of health care providers, resulting in confusion and depression. Physical disfigurements resulting from lupus-associated alopecia and rashes and corticosteroid-induced weight fluctuations were a major concern. These changes often affected self-image and libido, leading to strained personal relationships. Coping mechanisms that participants adopted included intense spiritual beliefs, ‘pushing through the difficult times’ and use of alternative therapies to relief symptoms was common. A poor understanding of SLE on the part of participant’s family and the community, coupled with the unpredictable course of the disease, exacerbated frustration and social exclusion. For most, limited income, lack of basic services, family dependencies, and comorbid diseases, such as human immune deficiency virus (HIV), exacerbated the daily negative SLE experiences.

Conclusion

In this study of mainly indigent South African women, SLE is associated with complex, chronic and challenging life experiences. The chronic relapsing and unpredictable nature of the disease, poor understanding and acceptance of SLE, compounded by a background of poverty, inadequate social support structures, negatively impact on a range of personal, social and vocational daily life experiences. Improved access to psychosocial services and SLE education might result in better outcomes.

Disability and health-related quality of life in Chinese patients with rheumatoid arthritis: A cross-sectional study

AIM

The objective of this study was to evaluate the impact of rheumatoid arthritis (RA) on physical function and health-related quality of life (HRQoL) in China.

METHOD

A cross-section survey was conducted in 21 general hospitals in China. Eight hundred and seven patients were recruited. Data on demographics, clinical data, physical function (Stanford Health Assessment Questionnaire Disability Index, HAQ-DI) and HRQoL (Study Short Form 36 Health Survey, SF-36) were collected on site.

RESULTS

In our cohort, physical function was impaired in 77.6% of patients (HAQ-DI >0). The median (interquartile range, IQR) of HAQ-DI was 0.750 (0.125, 1.500). Rated by HAQ-DI 0-1, >1-2, and >2-3, percentage of patients with mild, moderate and severe disability was 61.0%, 25.4%, and 13.6%, respectively. Older age, long disease duration, presence of extra-articular manifestations, tender joint count (TJC), overall status (assessed by patient Global Visual Analogue Scale [G-VAS] and physician G-VAS) and lacking disease-modifying anti-rheumatic drugs were identified as predictive factors for worse physical function (P < .05). The composite scores of SF-36 in the observed patients were: physical component summary 40.4 (IQR 27.4, 60.3), and mental component summary 49.0 (IQR 33.6, 70.9). Impaired physical health may be predicted by low income, presence of extra-articular manifestations, TJC, patient G-VAS and high HAQ-DI. Predictors for suboptimal mental health were low income, physical labor, married status, increased swollen joint count (SJC), physician G-VAS and high HAQ-DI.

CONCLUSION

Rheumatoid arthritis has profound effects on physical function and HRQoL in Chinese patients. Patients with identified predictive factors for poor outcome should be closely monitored.

Assessment of Quality of Life (QoL) in Systemic Lupus Erythematosus Patients at a Tertiary Care Hospital in Egypt

Systemic Lupus Erythematosus (SLE) has a profound impact on quality of life.

OBJECTIVE

The objective of this study was to explore the quality of life among Egyptian SLE patients and to assess its relationships with demographic and clinical features.

METHODS

One hundred sixty-four SLE patients were recruited for this study. Demographic information; clinical parameters; disease activity, as evaluated by the systemic lupus erythematosus Disease Activity Index; and organ damage, as assessed by the systemic lupus international Collaborative Clinics/American College of Rheumatology Damage Index, were reported. Quality of life was assessed with a quality of life questionnaire specifically designed for patients with systemic lupus erythematosus; the questions are grouped in the following six domains: physical function, sociooccupational activities, symptoms, treatment, mood, and self-image. Higher values indicate poorer quality of life.

RESULTS

Of the 164 Egyptian SLE patients who completed the survey, 142 (86.6%) were women. The mean age of the participants was 31± 8 years, the mean systemic lupus erythematosus disease activity index score was 17 ± 11, the mean systemic lupus international collaborative clinics/ American College of Rheumatology Damage Index score was 0.9 ± 1.2, and the mean quality of life score was 18.23± 6.89. Strong correlations were found between the total quality of life score and the scores for each domain of the questionnaire separately and disease activity, neurological manifestations, renal manifestations and musculoskeletal manifestations (p<0.0001); moreover, there was a significant positive correlation between the Systemic Lupus International Collaborative Clinics/American College of Rheumatology Damage Index score and the total quality of life score (p=0.005).

CONCLUSION

Poor quality of life among Egyptian SLE patients and disease activity are strongly related to impaired lifestyles in these patients.

External Validation of the Lupus Impact Tracker in a Southeastern US Longitudinal Cohort With Systemic Lupus Erythematosus

OBJECTIVE

To examine the external validity of the Lupus Impact Tracker (LIT), a systemic lupus erythematosus (SLE)-specific, health-related quality of life (HRQoL) tool in a population-based cohort of patients with SLE in Atlanta, Georgia. We modeled the association of LIT scores with patient-reported measures of SLE activity (Systemic Lupus Activity Questionnaire [SLAQ]) and organ damage (self-administered Brief Index of Lupus Damage [SA-BILD]). We investigated the association of LIT scores with general HRQoL using the Short Form 12 (SF-12).

METHODS

Correlation, multivariable regression, and longitudinal analyses using general linear modeling with fixed effects were performed to investigate the association between the LIT and patient-reported disease activity (SLAQ); patient-reported disease damage (SA-BILD); mental health (mental component summary [MCS] of the SF-12); and physical health (physical component summary [PCS] of the SF-12). Demographic trends related to the LIT were also assessed using cross-sectional analysis.

RESULTS

The LIT was significantly associated with disease activity (SLAQ), organ damage (SA-BILD), MCS scores, and PCS scores in both adjusted and unadjusted regression analysis (P < 0.0001). Longitudinal analysis demonstrated a significant association between the LIT and disease activity (SLAQ), MCS scores, and PCS scores (P < 0.0001), but not organ damage (SA-BILD).

CONCLUSION

The LIT is a simple, patient-centered tool that can be used to assess HRQoL in patients with SLE. This study provides external validity of the LIT in a population-based cohort with a large number of African American patients with a relatively high disease burden.

Health-related quality of life and utility: comparison of ankylosing spondylitis, rheumatoid arthritis, and systemic lupus erythematosus patients in Taiwan

The purpose of this study was to evaluate the health-related quality of life among patients with ankylosing spondylitis (AS), rheumatoid arthritis (RA), or systemic lupus erythematosus (SLE). This prospective, cross-sectional survey was conducted from September 1, 2008 to August 31, 2009. Patients answered questions with regard to demographics and disease characteristics and also completed generic (SF-36) and preference-based utility (SF-6D and EQ-5D) instruments. Multivariate analysis assessed the relationship of RA and SLE to AS with respect to the outcomes of the different health-related quality of life instruments. In general, baseline and disease characteristics differed across the three disease groups. Compared to SLE patients, RA patients scored worse on the higher-order summary scores of physical (PCS) and mental components (MCS) of SF-36 (P ≤ 0.002) and total SF-36 (P ≤ 0.005). RA also had worse PCS than AS (P ≤ 0.001). SLE patients scored higher on the utility score of SF-6D compared with RA patients and higher than both AS and RA patients for the utility score of EQ-5D. Multivariate analysis found that compared with AS patients, RA had significantly lower SF-36 total score and PCS, and SLE patients had greater PCS and a greater EQ-5D utility score. Multivariate analysis found no difference across the patient groups with respect to MCS or SF-6D utility score. These findings suggest that among the three rheumatic diseases studied, RA patients have the worse health-related quality of life, and AS patients have similar or poorer health-related quality of life as SLE patient.

The African Lupus Genetics Network (ALUGEN) registry: standardized, prospective follow-up studies in African patients with systemic lupus erythematosus

Background

The prevalence and severity of systemic lupus erythematosus (SLE) differs between ethnic groups and geographical regions. Although initially reported as rare, there is growing evidence that SLE is prevalent and runs a severe course in Africa. There is a paucity of prospective studies on African SLE patients.

Objective

The African Lupus Genetics Network (ALUGEN) is a multicentred framework seeking to prospectively assess outcomes in SLE patients in Africa. Outcomes measured will be death, hospital admission, disease activity flares, and SLE-related damage. We will explore predictors for these outcomes including clinical, serological, socio-demographic, therapeutic and genetic factors. Further, we will investigate comorbidities and health-related quality of life amongst these patients.

Methods

Data of patients recently (≤5 yrs) diagnosed with SLE will be collected at baseline and annual follow-up visits, and captured electronically. The ALUGEN project will facilitate standardized data capture for SLE cases in Africa, allowing participating centres to develop their own SLE registries, and enabling collaboration to enrich our understanding of inter-ethnic and regional variations in disease expression.

Conclusion

Comprehensive, high-quality multi-ethnic data on African SLE patients will expand knowledge of the disease and inform clinical practice, in addition to augmenting research capacity and networking links and providing a platform for future biomarker and interventional studies.

Quality of life and acquired organ damage are intimately related to activity limitations in patients with systemic lupus erythematosus

Background

Systemic lupus erythematosus (SLE) is an autoimmune multi-organ disease, characterized by episodes of disease flares and remissions over time, which may restrain affected patients’ ability to perform daily activities. The purpose of the present study was to characterize variation in activity limitations among well-defined SLE patients, and to describe disease phenotypes, acquired organ damage and their relations to activity limitation and self-reported health, respectively.

Methods

The disease phenotypes were organized into 4 different clinical groups and logistic regression analyses were used to identify how an elevated health assessment questionnaire (HAQ) score was related to disease variables such as phenotypes, disease activity and damage accrual. Correlation and multiple linear regression analyses were used to examine the association between each group of variables – background variables, disease variables and self-reported measurements – and the degree of elevated HAQ.

Results

We found a higher proportion of activity limitation in patients with skin and joint involvement compared to others. The presence of activity limitation, as detected by the HAQ instrument, was significantly associated with quality of life (EuroQol–5D) and accrual of organ damage using the Systemic Lupus International Collaborative Clinics/ACR damage index.

Conclusions

The findings highlight the differing requirements of the multi-professional rehabilitation interventions for the various SLE phenotypes in order to optimize the clinical care of the patients.

Patient-reported outcome measures for systemic lupus erythematosus clinical trials: a review of content validity, face validity and psychometric performance

Background

Despite overall progress in treatment of autoimmune diseases, patients with systemic lupus erythematosus (SLE) experience many inflammatory symptoms representing an unmet medical need. This study aimed to create a conceptual model of the humanistic and economic burden of SLE, and review the patient-reported outcomes (PROs) used to measure such concepts in SLE clinical trials.

Methods

A conceptual model for SLE was developed from structured review of published articles from 2007 to August 2013 identified from literature databases (MEDLINE, EMBASE, PsycINFO, EconLit) plus other sources (PROLabels, FDA/EMA websites, Clinicaltrials.gov). PROs targeting key symptoms/impacts were identified from the literature. They were reviewed in the context of available guidance and assessed for face and content validity and psychometric properties to determine appropriateness for use in SLE trials.

Results

The conceptual model identified fatigue, pain, cognition, daily activities, emotional well-being, physical/social functioning and work productivity as key SLE concepts. Of the 68 articles reviewed, 38 reported PRO data. From these and the other sources, 15 PROs were selected for review, including SLE-specific health-related quality of life (HRQoL) measures (n = 5), work productivity (n = 1), and generic measures of fatigue (n = 3), pain (n = 2), depression (n = 2) and HRQoL (n = 2). The Functional Assessment of Chronic Illness Therapy - Fatigue Scale (FACIT-Fatigue), Brief Pain Inventory (BPI-SF) and LupusQoL demonstrated the strongest face validity, conceptual coverage and psychometric properties measuring key concepts in the conceptual model. All PROs reviewed, except for three Lupus-specific measures, lacked qualitative SLE patient involvement during development. The Hospital Anxiety and Depression Scale (HADS), Short Form [36 item] Health Survey version 2 (SF-36v2), EuroQoL 5-dimensions (EQ-5D-3L and EQ-5D-5L) and Work Productivity and Activity Impairment Questionnaire: Lupus (WPAI:Lupus) showed suitability for SLE economic models.

Conclusions

Based on the identification of key symptoms and impacts of SLE using a scientifically sound conceptual model, we conclude that SLE is a condition associated with high unmet need and considerable burden to patients. This review highlights the availability and need for disease-specific and generic patient-reported measures of relevant domains of disease signs and symptoms, HRQoL and work productivity, providing useful insight for SLE clinical trial design.

Mental health status of women with rheumatoid arthritis in iran

Background:

Chronic diseases are usually accompanied by psychological abnormalities. Anxiety and depression occur in a significant number of patients with rheumatoid arthritis (RA). These psychological problems are likely, to be the results of chronic physical symptoms such as pain and disability.

Objectives:

The aim of this study was the evaluation of mental health in patients with rheumatoid arthritis in Iran.

Patients and Methods:

One hundred women with definite diagnosis of RA were evaluated in the outpatient clinic of the Tabriz University of Medical Sciences during one year period. Activity of RA disease was determined according to the Disease Activity Score-28 (DAS-28) scaling system and mental health was evaluated using the General Health Questionnaire-28 (GHQ-28). Based on the cut of point score of 22, prevalence of psychological problems was determined and a comparison was made the between two groups (with and without psychological problems).

Results:

GHQ28 screening test showed that psychological problems were seen in 49% of studied patients. There were significant difference between duration of disease and DAS-28 score between the two groups (P = 0.001 and P = 0.001, respectively). Somatic symptoms were more frequent in patients with psychological problems (P = 0.001). Somatic symptoms in patient with high disease activity was also more frequent than the other group (P = 0.002). There was a significant positive correlation between the scores of DAS-28 and GHQ-28 (r = 0.329, P = 0.001).

Conclusions:

This study showed that a considerable portion of patients with RA may have mental problems. The probability of these problems increased with more severe and more prolonged disease.

Challenges and opportunities in the early diagnosis and optimal management of rheumatoid arthritis in Africa and the Middle East

Early diagnosis and early initiation of disease-modifying antirheumatic drug (DMARD) therapy slow the progression of joint damage and decrease the morbidity and mortality associated with rheumatoid arthritis (RA). According to the European League Against Rheumatism (EULAR) guidelines, treatment should be initiated with methotrexate and addition of biological DMARDs such as tumour necrosis factor (TNF) inhibitors should be considered for RA patients who respond insufficiently to methotrexate and/or other synthetic DMARDs and have poor prognostic factors. Africa and the Middle East is a large geographical region with varying treatment practices and standards of care in RA. Existing data show that patients with RA in the region are often diagnosed late, present with active disease and often do not receive DMARDs early in the course of the disease. In this review, we discuss the value of early diagnosis and remission-targeted treatment for limiting joint damage and improving disease outcomes in RA, and the challenges in adopting these strategies in Africa and the Middle East. In addition, we propose an action plan to improve the overall long-term outlook for RA patients in the region.

Lupus in Africa: can we dispel the myths and face the challenges?

The epidemiology of systemic lupus erythematosus (SLE) in Africa is largely undetermined, and the perception persists that the incidence of SLE on the continent is very low. Recent studies as well as our own experience, however, suggest that this is not the case. We have conducted a survey amongst medical practitioners in Africa to determine their experiences of diagnosing and treating SLE patients, and the results suggest that significant numbers of African patients are presenting with SLE. The apparent low incidence rate in Africa may be the result of underdiagnosis due to poor access to health care, low disease recognition within primary health care settings, limited access to diagnostic tools and inadequate numbers of specialist physicians. Treatment of SLE in Africa is also restricted by availability and affordability of immunosuppressive drugs. We have established the African Lupus Genetics Network (ALUGEN), an informal network of clinicians and researchers in Africa who have an interest in SLE, in order to facilitate combined clinical and research efforts towards improved outcomes for African SLE patients.

Patterns and predictors of joint damage as assessed by the rheumatoid arthritis articular damage (RAAD) score in South Africans with established rheumatoid arthritis

This study aimed to determine the pattern and predictors of joint damage measured by the rheumatoid arthritis articular damage (RAAD) score and to describe its relationship to functional disability in patients with established rheumatoid arthritis (RA). One hundred Black patients with RA of disease duration ≥5 years were studied cross-sectionally. Data collected included socio-demographics, disease duration, smoking, body mass index (BMI), extraarticular features, rheumatoid factor (RF), haemoglobin (Hb), disease activity (DAS28), delay in disease-modifying antirheumatic drug initiation (DMARD lag) and treatment history. As outcome measures, the RAAD score and modified Health Assessment Questionnaire (mHAQ-DI) were used to assess joint damage and disability, respectively. Data were analysed by univariate and multivariate analyses. The mean RAAD score was 28.2 ± 12.8 for a mean disease duration of 17.5 ± 8.5 years. The majority of patients still had active disease (mean DAS28 4.4) and severe disability (mean mHAQ-DI 1.9), reflected in part by a long mean DMARD lag (9 years). Wrist and ankle joints were commonly involved. Multivariate analysis revealed that longer disease duration, higher RF titres and lower BMI were significant independent predictors of a higher RAAD score. The mHAQ-DI was significantly associated with DAS28, RAAD, education and Hb. Our results provide support for aspects of validity of the RAAD score and for its use in under-resourced settings. Further longitudinal studies are needed to evaluate its sensitivity to change in monitoring joint damage. Patterns of joint involvement and the inverse relationship between BMI and joint damage also merit further investigation in Black RA patients.

Predictors of self-reported health-related quality of life in systemic lupus erythematosus

OBJECTIVE

The Medical Outcomes Short Form-36 Survey (SF-36) has been widely used as a measure of health-related quality of life (HRQOL) in different populations. SLE patients have consistently reported lower scores compared with the general population. The objective of our study was to identify predictors of HRQOL using SF-36 among patients with SLE enrolled in a 2-year randomized controlled trial (RCT).

METHODS

We analysed 200 SLE patients enrolled in the Lupus Atherosclerosis Prevention Study (LAPS), an RCT of atorvastatin vs placebo, who completed SF-36 at qualifying, 12- and 24-month (final) visits.

RESULTS

At baseline, mean SF-36 domain scores were lower than those of age- and gender-matched population norms. There was no statistical difference reported between Physical Component Summary (PCS), Mental Component Summary and eight domain scores in the atorvastatin vs placebo group at 2 years. In multiple regression analyses, African American patients reported significantly lower scores in Physical Functioning compared with Caucasians. The presence of FM was significantly associated with lower scores in physical functioning, role physical, bodily pain, general health, vitality, social functioning and lower overall mean PCS scores. The Physician's Global Assessment of disease activity was associated with multiple SF-36 domains in univariate analysis.

CONCLUSION

This longitudinal study confirmed lower scores reported across all SF-36 domains. No one explanatory variable was independently associated with all domain scores. FM was independently associated with poorer HRQOL in most domains, underscoring the need for effective treatments for FM in SLE.

The need to address the burden of musculoskeletal conditions

Musculoskeletal conditions are common in men and women of all ages across all socio-demographic strata of society. They are the most common cause of severe long-term pain and physical disability and affect hundreds of millions of people around the world. They impact on all aspects of life through pain and by limiting activities of daily living typically by affecting dexterity and mobility. They affect one in four adults across Europe [1]. Musculoskeletal conditions have an enormous economic impact on society through both direct health expenditure related to treating the sequelae of the conditions and indirectly through loss of productivity. The prevalence of many of these conditions increases markedly with age, and many are affected by lifestyle factors, such as obesity and lack of physical activity. The burden of these conditions is therefore predicted to increase, in particular in developing countries. The impact on individuals and society of the major musculoskeletal conditions is reviewed and effective prevention, treatment and rehabilitation considered. The need to recognise musculoskeletal conditions as a global public health priority is discussed.

[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.

Functional disability and health-related quality of life in South Africans with early rheumatoid arthritis

BACKGROUND

The severity and predictors of functional disability and health-related quality of life (HRQoL) in a cohort of South Africans with early rheumatoid arthritis (RA) were investigated.

METHODS

Changes in the Health Assessment Questionnaire Disability Index (HAQ) and the 36-Item Short Form Health Survey (SF-36) following 12 months of traditional disease-modifying anti-rheumatic drugs (DMARDs) were studied in previously DMARD-naïve adults with disease duration ≤ 2 years.

RESULTS

The majority of the 171 patients were female (82%), Black Africans (89%) with a mean (SD) symptom duration of 11.6 (7.0) months. In the 134 patients seen at 12 months, there were significant improvements in the HAQ and all domains of the SF-36 but 92 (69%) still had substantial functional disability (HAQ > 0.5) and 89 (66%) had suboptimal mental health [SF-36 mental composite score (MCS) < 66.6]. Multivariate analysis showed that female sex (p = 0.05) and high baseline HAQ score (p < 0.01) predicted substantial functional disability at 12 months. Unemployment (p = 0.03), high baseline pain (p = 0.02), and HAQ score (p = 0.04) predicted suboptimal mental health, with a trend towards a low level of schooling being significant (p = 0.08).

CONCLUSIONS

Early RA has a broad impact on HRQoL in indigent South Africans, with a large proportion of patients still showing substantial functional disability and suboptimal mental health despite 12 months of DMARD therapy. Further research is needed to establish the role of interventions including psychosocial support, rehabilitation programmes, and biological therapy to improve physical function and HRQoL in this population.

An investigation of factors associated with the health and well-being of HIV-infected or HIV-affected older people in rural South Africa

Background

Despite the severe impact of HIV in sub-Saharan Africa, the health of older people aged 50+ is often overlooked owing to the dearth of data on the direct and indirect effects of HIV on older people’s health status and well-being. The aim of this study was to examine correlates of health and well-being of HIV-infected older people relative to HIV-affected people in rural South Africa, defined as participants with an HIV-infected or death of an adult child due to HIV-related cause.

Methods

Data were collected within the Africa Centre surveillance area using instruments adapted from the World Health Organization (WHO) Study on global AGEing and adult health (SAGE). A stratified random sample of 422 people aged 50+ participated. We compared the health correlates of HIV-infected to HIV-affected participants using ordered logistic regressions. Health status was measured using three instruments: disability index, quality of life and composite health score.

Results

Median age of the sample was 60 years (range 50–94). Women HIV-infected (aOR 0.15, 95% confidence interval (CI) 0.08–0.29) and HIV-affected (aOR 0.20, 95% CI 0.08–0.50), were significantly less likely than men to be in good functional ability. Women’s adjusted odds of being in good overall health state were similarly lower than men’s; while income and household wealth status were stronger correlates of quality of life. HIV-infected participants reported better functional ability, quality of life and overall health state than HIV-affected participants.

Discussion and conclusions

The enhanced healthcare received as part of anti-retroviral treatment as well as the considerable resources devoted to HIV care appear to benefit the overall well-being of HIV-infected older people; whereas similar resources have not been devoted to the general health needs of HIV uninfected older people. Given increasing numbers of older people, policy and programme interventions are urgently needed to holistically meet the health and well-being needs of older people beyond the HIV-related care system.

Health of adults caring for orphaned children in an HIV-endemic community in South Africa

In South Africa, an estimated 2.5 million children have been orphaned by AIDS and other causes of adult mortality. Although there is a growing body of research on the well-being of South African orphaned children, few research studies have examined the health of adult individuals caring for children in HIV-endemic communities. The cross-sectional survey assessed prevalence of general health and functioning (based on Short-Form 36 version 2 scale), depression (based on Center for Epidemiologic Studies-Depression scale), anxiety (using Kessler-10 scale), and post-traumatic stress (using the Harvard Trauma Questionnaire) among a representative community sample of adults caring for children in Umlazi Township, an HIV-endemic community in South Africa. Of 1599 respondents, 33% (n=530) were carers of orphaned children. Results showed that, overall, carers reported poor general health and functioning and elevated levels of depression, anxiety, and post-traumatic stress. Carers of orphaned children reported significantly poorer general health and functioning and higher rates of depression and post-traumatic stress compared with carers of non-orphaned children. In multivariate analyses, orphan carer and non-orphan carer differences in general health were accounted for by age, gender, education, economic assets, and source of income, but differences in depression were independent of these cofactors. Interventions are needed to address physical and mental health of carers in general. Greater health problems among orphan carers appeared to be fully explained by socioeconomic characteristics, which offer opportunities for targeting of programs. More research is needed to understand determinants of mental health disparities among orphan carers, which were not explained by socioeconomic characteristics.

Quality-of-life measurements versus disease activity in systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a chronic disease affecting the physical, social, and psychological well-being of patients. Different instruments have been developed to measure health-related quality of life, some of which are SLE-specific. Contributors to poor quality of life in patients with SLE include fatigue, fibromyalgia, depression, and cognitive dysfunction. Health-related quality of life is not strongly associated with disease activity or organ damage. The Medical Outcomes Survey Short Form 36 is the most common instrument used to measure quality of life in SLE.

Quality of life and satisfaction with life in SLE patients-the importance of clinical manifestations

To assess the correlation between quality of life (QoL) and satisfaction with life (SL) in SLE patients and correlate both with clinical symptoms of the disease. The study was performed in 83 patients. QoL was assessed by Short Form 36, and SL was assessed by the Satisfaction with Life Scale. Clinical manifestations presented at the time of examination were taken into consideration. SLE patients assessed their QoL and SL as rather low. Those with photosensitivity as well as neurological symptoms presented lower QoL in particular domains, while those with renal manifestation of SLE assessed their QoL as higher. Similar observations were made for SL only in relation to neurological symptoms. Moreover, our findings show that although SL is a part of QoL, both these parameters should be distinguished in order to fully assess the state of the patient.

Health-related quality of life, employment and disability in patients with Sjogren's syndrome

OBJECTIVE

To compare health-related quality of life (HR-QOL), employment and disability of primary and secondary SS (pSS and sSS, respectively) patients with the general Dutch population.

METHODS

HR-QOL, employment and disability were assessed in SS patients regularly attending the University Medical Center Groningen (n = 235). HR-QOL, employment and disability were evaluated with the Short Form-36 questionnaire (SF-36) and an employment and disability questionnaire. Results were compared with Dutch population data (matched for sex and age). Demographical and clinical data associated with HR-QOL, employment and disability were assessed.

RESULTS

Response rate was 83%. SS patients scored lower on HR-QOL than the general Dutch population. sSS patients scored lower on physical functioning, bodily pain and general health than pSS patients. Predictors for reduced HR-QOL were fatigue, tendomyalgia, articular involvement, use of artificial saliva, use of anti-depressants, comorbidity, male sex and eligibility for disability compensation (DC). Employment was lower and DC rates were higher in SS patients compared with the Dutch population.

CONCLUSION

SS has a large impact on HR-QOL, employment and disability.

The influence of treatment on quality of life in systemic lupus erythematosus patients

OBJECTIVE

Systemic lupus erythematosus is an autoimmune disease with uncertain prognosis as to the course. The patients need pharmacotherapy all their life. The main aim of this study was to determinate the impact of therapeutic schedules on patients' quality of life.

METHODS

The study was performed on 83 patients who were divided into five groups according to methods of treatment used. Quality of life was measured using MOS SF-36.

RESULTS

Obtained results revealed that therapeutic schedules have the highest influence on patients' social functioning. The more medicaments the patients use, the lower their quality of life.

CONCLUSIONS

The type of medicaments and therapeutic schemes adopted affect the patients' quality of life. Nevertheless, quality of life and the patients' attitude to it are very subjective and are also influenced by the clinical state of the patients as well as many other factors such as socioeconomic and demographic.

The prevalence and associations of sleep disturbances in patients with systemic lupus erythematosus

The aim of this study was to analyze sleep complaints in patients with systemic lupus erythematosus (SLE) and to determine its prevalence and associations. Fifty outpatients with SLE and an equal number of age- and sex-matched controls were included in the study. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) in both cases and controls. Depressed mood, functional disability and pain severity were assessed in patients using standardized questionnaires. Disease severity, cumulative damage and presence of fibromyalgia were determined by clinical examination. Bivariate associations between sleep quality and disease-related variables as well as demographic variables were calculated. A series of hierarchical regression analyses were computed to determine the independent determinant of sleep quality. PSQI scores were significantly higher in patients with SLE. Prevalence of sleep disturbance was 62%. Functional disability, disease activity and depressed mood correlated positively with sleep disturbances. 36% of the patients satisfied ACR criteria for fibromyalgia. In multiple regression analyses disease activity was found to be an independent determinant of sleep quality. The prevalence of poor sleep quality in patients with SLE was higher than it is generally perceived to be. Functional disability, disease activity and depressed mood contributed significantly to sleep disturbances in SLE.

Factors associated with functional disability in patients with rheumatoid arthritis

To determine factors associated with functional disability in patients with rheumatoid arthritis (RA). A total of 100 RA patients were reviewed retrospectively. Multiple regression analysis was used to investigate associations between the dependent variable (health assessment questionnaire) and independent variables (age, disease duration, hand grip strength values, VAS and DAS-28 scores). Main factors associated with functional disability were disease activity score as reflected in a high score on the DAS-28 (r=0.68, p<0.001) and disease duration (r=0.23, p<0.05). Increased age, decreased grip strength and high pain level were associated with lower functional ability, but none of these was a predictor of disability in the regression model. The results indicate that age, disease duration, disease activity, pain intensity and hand grip strength are related to physical disability in patients with RA. However, only disease activity has an impact on physical function. Thus, treatment of RA patients should focus on early inhibition of disease activity in order to achieve a good functional outcome.

Social aspects of living with rheumatoid arthritis: a qualitative descriptive study in Soweto, South Africa - a low resource context

Background

Rheumatoid Arthritis (RA) is a chronic illness with important functional, social and employment consequences. We therefore undertook a cross-sectional study, using the International Classification of Functioning, Disability and Health framework, to investigate the personal and social consequences of RA in women, living under largely impoverished conditions.

Methods

A qualitative case study design was used with a convenience sample of 60 women with RA living in Soweto, South Africa. Semi-structured in-depth interviews were conducted to cover a range of experiences including onset of disease, treatment, environmental barriers and facilitators, employment, and social inclusion in family and community life. The outcomes are described according the International Classification of Functioning, Health and Disability framework at the body, person and societal levels and looking at both personal and environmental factors.

Results

The main features of living with RA were pain, muscle stiffness at the body level, difficulties in doing various activities such as mobility, washing, dressing, domestic activities, using transport and obtaining and maintaining employment at the person level. At the societal level the participants described difficulties moving around, interacting socially and taking part in community activities, fulfilling social roles and earning a living. Environmental facilitators such as assistive devices and health care services improved functioning. Barriers such as physical environments, lack of transport and basic services, such as electricity, and attitudes of others lead to social exclusion, loss of a sense of self and independence. Low income, lack of sufficient public transport, and sparse basic services were poverty features that exacerbated negative experiences.

Conclusion

The experiences of living with RA in a low resource context are similar to those in mid- and high resource contexts, but are exacerbated by poverty and the lack of basic services. Pain and social exclusion are some of the key experiences of women with RA living in Soweto. The ICF provides a useful framework for describing and understanding the complexity of these experiences.

Concepts important to persons with systemic lupus erythematosus and their coverage by standard measures of disease activity and health status

OBJECTIVE

To explore the array of concepts important to patients with chronic systemic lupus erythematosus (SLE) and to compare these with instruments assessing disease activity, damage, and health status.

METHODS

We conducted a qualitative focus-group study of patients with SLE concerning their problems in daily functioning. The group sessions were tape recorded, transcribed, and divided into meaning units. The concepts contained in these meaning units were extracted and linked to the International Classification of Functioning, Disability and Health (ICF). We then compared the concepts from the focus groups with those concepts covered by SLE activity scores, the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI), and the Short Form 36 Health Survey (SF-36).

RESULTS

A total of 92 concepts emerged from 5 focus groups; of these, 28 related to body functions and structures, 24 to activities and participation, and 25 to environmental factors. Two concepts were linked to the health condition itself and 6 to personal factors. Seven were not covered by the ICF. Of the 28 concepts regarding body functions and structures, 24 (86%) were covered by the combination of activity scores and the SDI. The SF-36 also addressed 3 of these concepts and contained 9 (38%) of 24 concepts in activities and participation.

CONCLUSION

Although the combination of SLE activity scores, SDI, and SF-36, as suggested for SLE studies, well covers body functions and structures and includes a significant portion of problems regarding activities and participation, neither environmental nor personal factors are covered at all.

Using the Short Form 6D, as an overall measure of health, to predict damage accrual and mortality in patients with systemic lupus erythematosus: XLVII, results from a multiethnic US cohort

OBJECTIVE

To determine if overall health status as assessed by the Short Form 6D (SF-6D) index, a preference-based generic measure of health, is associated with the occurrence of damage accrual and mortality in patients with systemic lupus erythematosus (SLE).

METHODS

We studied SLE patients (American College of Rheumatology criteria) from the LUpus in MInorities, NAture versus nurture cohort (LUMINA), a longitudinal multiethnic cohort. The contribution of the SF-6D as assessed at enrollment to damage accrual at the last visit and mortality was examined. All variables previously shown to be determinants of damage accrual and mortality and corroborated by univariable analyses were adjusted for in multivariable models (Poisson and Cox proportional hazards regressions, respectively). Damage accrual and mortality were the dependent variables. Similar analyses were performed examining the associations of the Short Form 36 summary measures (physical component summary [PCS], mental component summary [MCS]) with these outcomes.

RESULTS

In 552 patients, the SF-6D was negatively associated with damage accrual and mortality in the univariable analyses; the association with damage was confirmed in the multivariable analyses (chi(2) = 9.020, P = 0.002) but the association with mortality was not confirmed (hazard ratio 0.495, 95% confidence interval 0.041-6.038). When the PCS and MCS were evaluated, the PCS, but not the MCS, was found to be associated with damage but not with mortality.

CONCLUSION

The SF-6D (and the PCS) as measured early in the disease course were found to independently predict damage accrual at the last visit, but not mortality. Although the SF-6D was originally conceived as a utility measure, it may be used to accurately assess overall health status in patients with SLE.
