The health-related quality of life of people living with HIV/AIDS

The factor structure of the Hopkins Symptom Checklist 25 among persons seeking HIV testing

Rates of anxiety and depression are high among individuals living with HIV. The Hopkins Symptom Checklist (HSCL) is a screening tool to identify symptoms of depression and anxiety. The objective of this study was to determine the factor structure of the 25-item HSCL in a population-based sample of individuals seeking HIV testing in the Western Cape in South Africa. Participants volunteered for HIV testing at two non-medical HIV testing sites in the Western Cape. We used convenience sampling to administer the scale prior to their undergoing HIV testing. Data were analysed using exploratory factor analysis, using an extraction method of principal components with Promax (oblique) rotation. The Cronbach's alpha reliability indices were calculated for each of the independent factors to determine internal consistency. Factor analysis revealed a three-factor structure that explained 56.86% of the total variance. These factors included depression (14 items), anxiety (7 items) and somatic symptoms (4 items). Alpha levels ranged from 0.67 to 0.94. We found that the HSCL is a reliable measure for depression and anxiety, and consists of 3 distinguishable factors depression, anxiety, and somatic symptoms.

Empirical Development of a Behavioral Intervention for African American/Black and Latino Persons with Unsuppressed HIV Viral Load Levels: An Application of the Multiphase Optimization Strategy (MOST) Using Cost-Effectiveness as an Optimization Objective

We used results from an optimization randomized controlled trial which tested five behavioral intervention components to support HIV antiretroviral adherence/HIV viral suppression, grounded in the multiphase optimization strategy and using a fractional factorial design to identify intervention components with cost-effectiveness sufficiently favorable for scalability. Results were incorporated into a validated HIV computer simulation to simulate longer-term effects of combinations of components on health and costs. We simulated the 32 corresponding long-term trajectories for viral load suppression, health related quality of life (HRQoL), and costs. The components were designed to be culturally and structurally salient. They were: motivational interviewing counseling sessions (MI), pre-adherence skill building (SB), peer mentorship (PM), focused support groups (SG), and patient navigation (short version [NS], long version [NL]. All participants also received health education on HIV treatment. We examined four scenarios: one-time intervention with and without discounting and continuous interventions with and without discounting. In all four scenarios, interventions that comprise or include SB and NL (and including health education) were cost effective (< $100,000/quality-adjusted life year). Further, with consideration of HRQoL impact, maximal intervention became cost-effective enough to be scalable. Thus, a fractional factorial experiment coupled with cost-effectiveness analysis is a promising approach to optimize multi-component interventions for scalability. The present study can guide service planning efforts for HIV care settings and health departments.

Preference-based measures of health-related quality of life in Indigenous people: a systematic review

PURPOSE

In many countries, there are calls to address health inequalities experienced by Indigenous people. Preference-based measures (PBMs) provide a measurement of health-related quality of life and can support resource allocation decisions. This review aimed to identify, summarize, and appraise the literature reporting the use and performance of PBMs with Indigenous people.

METHODS

Eleven major databases were searched from inception to August 31, 2022. Records in English that (1) assessed any measurement property of PBMs, (2) directly elicited health preferences, (3) reported the development or translation of PBMs for Indigenous people, or (4) measured health-related quality of life (HRQL) using PBMs were included. Ethically engaged research with Indigenous people was considered as an element of methodological quality. Data was synthesized descriptively (PROSPERO ID: CRD42020205239).

RESULTS

Of 3139 records identified, 81 were eligible, describing psychometric evaluation (n = 4), preference elicitation (n = 4), development (n = 4), translation (n = 2), and HRQL measurement (n = 71). 31 reported ethically engaged research. Reports originated primarily from Australia (n = 38), New Zealand (n = 20), USA (n = 9) and Canada (n = 6). Nearly all (n = 73) reported indirect, multi-attribute PBMs, the most common of which was the EQ-5D (n = 50).

CONCLUSION

A large number of recent publications from diverse disciplines report the use of PBMs with Indigenous people, despite little evidence on measurement properties in these populations. Understanding the measurement properties of PBMs with Indigenous people is important to better understand how these measures might, or might not, be used in policy and resource decisions affecting Indigenous people.

Validity of the patient health questionnaires (phq-2 and phq-9) for screening depression among human immunodeficiency virus patients in Lahore, Pakistan

BACKGROUND

Many human immunodeficiency virus (HIV) infected patients suffer from depr-ession, but a little focus is given to detecting and treating depression in primary health care. Detection of depression can be improved by introducing short, reliable, and valid screening instruments.

AIM

To determine the psychometric properties of the patient health questionnaire-2 (PHQ-2) and patient health questionnaire-9 (PHQ-9) for depression screening and diagnosis, and the sensitivity and specificity of the PHQ-2 in HIV infected patients.

METHODS

A cross-sectional study was conducted on 158 HIV-infected patients aged 18 years and above in Lahore, Pakistan. PHQ-2 was implemented to screen depression. PHQ-9 was implemented to diagnose major depressive disorder as a reference standard. Reliability, Validity tests and receiver operating characteristic curve were computed.

RESULTS

The Cronbach's alpha of PHQ-2 and PHQ-9 were 0.732 and 0.759, respectively. The study results showed that the score of 2 on PHQ-2 indicates the highest Youden's index of 0.924, with both sensitivity and specificity of 0.96, and the area under the curve for PHQ-2 was 0.98 (95%CI: 0.953-0.998).

CONCLUSION

Good psychometric properties for the PHQ-2 and PHQ-9 indicated their significant potential as tools for depression screening and diagnosis in the HIV-infected population.

Improving health-related quality of life instrument translation into South African languages

Background

Most health-related quality of life (HRQoL) instruments have been created in English, which can influence their reliability and validity in non-English speaking populations. This study assessed the translation methodology of HRQoL instruments that have been used and translated into South African languages and which could be applied in cost-utility analyses (CUAs).

Methods

A 2019 systematic review was updated with searches conducted in Medline, the Web of Science^TM (WoS^TM) Core Collection and the South African SciELO collection via the WoS^TM Platform. Additional searches in Sabinet’s African Journals database and on instrument developers’ webpages were performed. Only HRQoL instruments suitable for CUAs were included. Articles reporting at least one element of the translation methods were included. Established good practice principles were used to evaluate the translation methodology.

Results

Within the 39 publications identified, a dozen translated instruments have been used in South Africa. All instruments used were translated from English and none had originally been created in South Africa. Instrument developers’ translations were used more than study investigators’ translations. Almost all instrument developer versions met the full translation criteria. No investigator translated instrument met the full translation criteria primarily because recommendations on forward and back translations were not followed. However, this analysis was hampered by a lack of methodological reporting details. The most used instruments, which also had the most translated versions available, were the EQ-5D-3L, SF-36 version 2 and EORTC QLQ-C30.

Conclusion

Instrument developers’ translations more often met recommended translation methodology compared with investigators’ versions. The EQ-5D-3L may be best suited for South African economic evaluations and for use in clinical practice, but further work may be needed.

"Pain Special Issue" "Stakeholders' perspectives and requirements on pain self-management for adolescents living with HIV/AIDS in Malawi: a cross-sectional qualitative study"

Malawi has one of the highest HIV prevalence rates (8.9%), and data suggest 27% pain prevalence among adolescents living with HIV (ALHIV) in Malawi. Pain among ALHIV is often under-reported and pain management is suboptimal. We aimed to explore stakeholders' perspectives and experiences on pain self-management for ALHIV and chronic pain in Malawi. We conducted cross-sectional in-depth qualitative interviews with adolescents/caregiver dyads and healthcare professionals working in HIV clinics. Data were audio-recorded, transcribed verbatim and translated (where applicable) then imported into NVivo version 12 software for framework analysis. We identified three main themes: (1) Experiencing "total pain": adolescents experienced physical, psychosocial, and spiritual pain which impacted their daily life activities. (2) Current self-management approaches: participants prefer group-based self-management approaches facilitated by healthcare professionals or peers at the clinic focussing on self-management of physical, psychosocial, and spiritual pain. (3) Current pain strategies: participants used prescribed drugs, traditional medicine, and non-pharmacological interventions, such as exercises to manage pain. A person-centred care approach to self-management of chronic pain among ALHIV is needed to mitigate the impact of pain on their daily activities. There is a need to integrate self-management approaches within the existing structures such as teen clubs in primary care.

Managing pain in HIV/AIDS: a therapeutic relationship is as effective as an exercise and education intervention for rural amaXhosa women in South Africa

Background

Pain is one of the most prevalent symptoms in people living with HIV/AIDS and is largely undermanaged. Both a peer-led exercise and education Positive Living programme (PL programme) and the PL programme workbook alone were previously found to be effective in reducing pain in urban amaXhosa Women Living With HIV/AIDS (WLWHA). A therapeutic relationship was hypothesised to have contributed to the efficacy of both interventions. The aim of the study was to determine the effectiveness of the PL programme and a therapeutic relationship, compared to a therapeutic relationship alone in managing pain amongst rural amaXhosa WLWHA on pain severity and pain interference, and secondary outcomes, symptoms of depression, health-related quality of life (HRQoL) and self-efficacy.

Methods

In this two-group, single-blind, pragmatic clinical trial with stratified convenience sampling, the PL programme and therapeutic relationship, was compared to a therapeutic relationship alone in rural amaXhosa WLWHA. The PL programme was a 6-week, peer-led intervention comprising education on living well with HIV, exercise and goal setting. The therapeutic relationship comprised follow-up appointments with a caring research assistant. Outcome measures included pain severity and interference (Brief Pain Inventory), depressive symptoms (Beck Depression Inventory), HRQoL (EuroQol 5-Dimensional outcome questionnaire) and self-efficacy (Self-efficacy for Managing Chronic Disease 6-Item Scale). Follow-up was conducted at 4, 8, 12, 24, and 48 weeks. Mixed model regression was used to test the effects of group, time, and group and time interactions of the interventions on outcome measures.

Results

Forty-nine rural amaXhosa WLWHA participated in the study: PL group n = 26; TR group n = 23. Both intervention groups were similarly effective in significantly reducing pain severity and interference and depressive symptoms, and increasing self-efficacy and HRQoL over the 48 weeks. A clinically important reduction in pain severity of 3.31 points occurred for the sample over the 48 weeks of the study. All of these clinical improvements were obtained despite low and suboptimal attendance for both interventions.

Conclusions

Providing a therapeutic relationship alone is sufficient for effective pain management amongst rural amaXhosa WLWHA. These findings support greater emphasis on demonstrating care and developing skills to enhance the therapeutic relationship in healthcare professionals working with rural amaXhosa WLWHA.

Assessment of Health-Related Quality of Life Among Patients Infected With HIV Receiving Care in a Nigerian Tertiary Hospital

OBJECTIVES

Globally, an appropriate estimate of the health-related quality of life (HRQoL) of people living with HIV/AIDS (PLWHA) is essential for the economic evaluation of antiretroviral therapy (ART) programs to ensure optimal value for money. Therefore, this article aimed to evaluate the HRQoL of PLWHA on ART and to explore its predictors.

METHODS

A cross-sectional study was conducted among PLWHA in an ART clinic of a Nigerian tertiary hospital. The participants were selected through a computer-based simple random sampling technique. The study instrument used for data collection was the English-language version of the European Quality of Life (EQ-5D-5L). The participants completed the questionnaire in the waiting room of the clinic, and the patients' clinical data were retrieved from their medical records. Descriptive statistics and multivariate linear regression were used for data analysis. P<.05 was considered statistically significant.

RESULTS

Out of the 352 participants, the majority were female (66.5%), and more than half (56.2%) had a CD4 count fewer than 500 cells/mm³. The EQ-5D index and utility score of the study population were 0.72 ± 4.18 and 73.05 ± 10.36, respectively. The significant predictors of EQ-5D index were the number of children (β = -0.215, P=.026), CD4 count (β = 0.171, P=.030), and duration on ART (β = -0.144, P=.011).

CONCLUSIONS

Our findings suggest that PLWHA receiving ART in Nigeria had good HRQoL. However, concerted efforts targeted at improving CD4 cell count and reducing the family burden of PLWHA would enhance their HRQoL.

Pain in Clients Attending a South African Voluntary Counseling and Testing Center Was Frequent and Extensive But Did Not Depend on HIV Status

BACKGROUND

The frequency of pain is reported to be high in people living with HIV, but valid comparisons between people living with HIV and HIV-negative cohorts are rare. We investigated whether HIV infection influenced frequency and characteristics of pain in adults undergoing voluntary testing for HIV.

SETTING

Participants were recruited from an HIV voluntary counseling and testing center at the Chris Hani Baragwanath Academic Hospital, Soweto, South Africa.

METHODS

Pain was assessed using the Wisconsin Brief Pain Questionnaire. Depressive and anxiety symptomatology was determined using the Hopkins Symptom checklist-25. We then stratified by HIV status.

RESULTS

Data from 535 black South Africans were analyzed: HIV-infected n = 70, HIV-uninfected n = 465. Overall, frequency of any current pain was high with 59% [95% confidence interval (CI): 55 to 63, n: 316/535] of participants reporting pain, with no difference related to HIV status: HIV-infected 50% (95% CI: 37 to 61, n: 35/70), HIV-uninfected 60% (95% CI: 56 to 65, n: 281/465). Pain intensity and number of pain sites were similar between the groups as were symptoms of anxiety and depression: mean Hopkins Symptom Checklist-25 1.72 (95% CI: 1.57 to 1.87) HIV-infected participants and 1.68 (95% CI: 1.63 to 1.73) HIV-uninfected participants. Univariate analysis showed female sex and greater depressive and anxiety symptomatology associated with pain. In a multivariable modeling, only depressive and anxiety symptomatology was retained in the model.

CONCLUSION

The high frequency of pain found in both HIV-infected and HIV-uninfected individuals presenting at a voluntary counseling and testing center was more likely to be associated with depression and anxiety, than with the presence or absence of HIV.

Functional outcome of stroke inpatients according to human immunodeficiency virus status: A feasibility study

Background

Stroke in human immunodeficiency virus positive (HIV+) individuals is becoming an increasing concern. Being significantly younger than typical stroke patients, the impact of functional challenges on quality of life and burden on society becomes more eminent.

Objectives

This feasibility study aims to determine the requirements for a large descriptive cohort, to adequately describe the functional outcome of stroke patients with varying HIV status.

Method

All stroke patients meeting the inclusion criteria were recruited over a 6-month period at a South African inpatient rehabilitation centre. Data were collected on admission and discharge using outcome measures including the Barthel Index (BI), Berg Balance Scale (BBS) and the use of assistive devices used to describe independence with activities of daily living (ADL), mobility and safety post-stroke. Statistical analysis was performed using Stata version 14.2.

Results

The feasibility study identified appropriate procedures and barriers to a successful study in addition to describing preliminary data on participant demographics, relevant medical history and functional outcomes post-stroke. Limitations that affected feasibility included minimal recruitment sites, length of data collection period, timely communication of participant discharge plans and dates, and confirmation of participant HIV status. An appropriate comparison between sub-groups could not be made because of disproportionate group sizes, median age differences and no assessor blinding.

Conclusion

To increase generalisability and the understanding of the unique HIV+ stroke profile, multiple recruitment sites, longer data collection periods, assessor blinding and age-matched groups with HIV status confirmation are recommended.

Common impairments and functional limitations of HIV sequelae that require physiotherapy rehabilitation in the medical wards at Queen Elizabeth Central Hospital, Malawi: A cross sectional study

Introduction

The progression of human immunodeficiency virus (HIV) to acquired immune deficiency syndrome (AIDS) and the use of anti-retroviral therapy (ART) have resulted in a range of complications, which affect different body systems and result in functional limitations and disabling impairments.

Objective

To investigate HIV-related impairments and functional limitations that require physiotherapy rehabilitation in patients admitted to the medical wards at Queen Elizabeth Central Hospital in Blantyre, Malawi.

Methods

This was a descriptive quantitative cross-sectional study involving the participation of 32 female (59.3%) and 22 male (40.7%) adults living with HIV and admitted to the medical wards at Queen Elizabeth Central Hospital. We collected data using a questionnaire that consisted of the World Health Organization Disability Assessment Schedule 2 (WHODAS2.0) and some demographic questions. Results were analysed using the Statistical Package for the Social Sciences (SPSS).

Results

Participation in society was the most frequently reported functional complication; the least common limitation was getting along with people (70.3%, n = 38 participants) and interaction with others (24%; n=13). Shortness of breath (55%; n=30), muscle weakness (44.4%; n=24) and joint and muscle pain (37%; n=20) were the most commonly reported impairments. Participation restriction in the society affected both males (77.3%) and females (70.7%). The least common limitation that required physiotherapy for both males and females was getting along with people (26.6% and 25%, respectively). On average, male and female participants had a disability severity score of 48.5±4.6 and 42.2±22.8, respectively.

Conclusion

Our data showed that there is a clear need for early intervention to halt or delay the progression of complications to avoid severe disability; this is not only good for the patient but also for the socioeconomic state of the nation. Timely and full functional assessment, as well as referral of people living with HIV/AIDS for rehabilitation, is an important step forwards.

Classification and description of chronic pain among HIV positive patients in Uganda

INTRODUCTION

Chronic pain classification in HIV positive patients is essential for diagnosis and treatment. However, this is rarely done despite association with poor outcomes.

METHODS

A cross-sectional survey of 345 consented patients at a specialized HIV care center in Uganda was conducted. Chronic pain was defined as pain of more than two weeks duration. Data was collected using a socio-demographic questionnaire, the IASP classification of chronic pain; the StEP; Mini Mental Status Examination, Patient Health Questionnaire, Mini International Neuropsychiatric Interview and the World Health Organization quality of life instrument brief version. Chi-square, Fisher's exact, t-test and logistic regression analyses were carried out to determine factors associated with chronic pain.

RESULTS

Description of pain aetiology was difficult. Chronic pain was reported in 21.5% of the participants. Non-neuropathic (92.0%) was more common than neuropathic pain (8.0%). Chronic pain was found to be associated with feeling ill [OR=6.57 (3.48 - 12.39)], and worse scores in the quality of life domain for physical health [OR=0.71 (0.60 - 0.83)].

CONCLUSION

People living with HIV/AIDS commonly have chronic pain that is associated with poor quality of life. More sensitive tools are needed to accurately describe chronic pain in resource limited settings.

Is symptom prevalence and burden associated with HIV treatment status and disease stage among adult HIV outpatients in Kenya? A cross-sectional self-report study

People with HIV experience a high prevalence and burden of physical and psychological symptoms throughout their disease trajectory. These have important public and clinical health implications. We aimed to measure: the seven-day period prevalence of symptoms, the most burdensome symptoms, and determine if self-reported symptom burden is associated with treatment status, clinical stage and physical performance. We conducted a cross-sectional study among adult (aged at least 18 years) patients with HIV, attending HIV outpatient care in Kenya. Data was gathered through self-report using the Memorial Symptom Assessment Scale-Short Form (MSAS-SF), file extraction (sociodemographic data, treatment status, CD4 count, clinical stage) and through observation using the Karnofsky Performance Scale (KPS). Multivariable ordinal logistic regression assessed the association of symptom burden (MSAS-SF) controlling for demographic and clinical variables. Of the 475 participants approached, 400 (84.2%) participated. Ordinal logistic regression showed that being on HIV treatment was associated lower global distress index (in quartiles) (odds ratio .45, 95% CI .23 to .88; p = 0.019). Pain and symptom burden still persist in the era of antiretroviral therapy. Routine clinical practice should incorporate assessment and management of pain and symptoms irrespective of disease stage and treatment status in order to achieve the proposed fourth ^"90" in the UNAIDS 90-90-90 targets (that is good quality of life).

Improvements in health-related quality of life and function in middle-aged women with chronic diseases of lifestyle after participating in a non-pharmacological intervention programme: A pragmatic randomised controlled trial

Background

Musculoskeletal diseases consume a large amount of health and social resources and are a major cause of disability in both low- and high-income countries. In addition, patients frequently present with co-morbid chronic diseases of lifestyle. The area of musculoskeletal disease is restricted by a lack of epidemiological knowledge, particularly in low- and middle-income countries.

Objectives

This pragmatic randomised controlled trial assessed the benefits of a 6-week physiotherapy intervention for middle-aged women with musculoskeletal conditions compared to usual care.

Method

A weekly 2-h educational programme utilising a workbook, discussion group and exercise class was presented for the intervention group, while the control group received usual care. The primary outcome was health-related quality of life. Parametric and non-parametric data were used to determine the equivalence between the groups.

Results

Twenty-two participants were randomised to the intervention and 20 to the control group. The control group demonstrated no within-group improvement in health-related quality of life items, compared to significant improvements in two items in the intervention group. The change in median utility score within the intervention group was twice as large as the change in the control group. With regard to self-efficacy, the intervention group demonstrated significant within-group changes in perceived management of fatigue and discomfort.

Conclusion

The positive impact of the intervention on the participants suggests that the programme should continue at the clinic in question, but should be presented at a more convenient time for participants who work, as recruitment to the study was less than anticipated. Primary health care systems in South Africa urgently need to put structures in place for effective management of the functional impact of chronic diseases of lifestyle and musculoskeletal conditions. It is time for physiotherapists and possibly other health care professionals to participate in the development of appropriate community level interventions to address the functioning and quality of life of individuals living with the diseases.

Health-related quality of life in peritoneal dialysis patients: A narrative review

Health-related quality of life (HRQOL) is an important aspect of patients´ health that should be an integral part of the evaluation of patient-centered outcomes, not least because HRQOL associates with patients´ morbidity and mortality. This applies also to chronic kidney disease patients, including those dependent on renal replacement therapies, the type of which may influence patients´ perception of HRQOL. Several studies have addressed HRQOL in chronic kidney disease patients undergoing renal replacement therapies, especially transplanted patients and hemodialysis patients, while publications concerning peritoneal dialysis (PD) patients are scarcer. This review describes some of the methods used to assess HRQOL, factors influencing HRQOL in PD patients, HRQOL in PD vs hemodialysis, and the relation between HRQOL and patient outcomes. We conclude that assessment of HRQOL-often neglected at present-should be included as a standard measure of patient-centered outcomes and when monitoring the quality and effectiveness of renal care including PD treatment.

Common mental disorders and psychological adjustment among individuals seeking HIV testing: a study protocol to explore implications for mental health care systems

Background

In an effort to promote greater access to voluntary counseling and testing for HIV, it has become practice in many countries, including South Africa, to establish non-medical testing sites and to de-couple HIV testing from other medical and mental health care services. While it is well established that HIV infection is associated with a range of psychopathology, much of the literature has assumed that it is receipt of an HIV positive diagnosis that causes people to become depressed, traumatized, or develop other psychiatric symptoms. Empirical data about the baseline psychiatric condition and mental health care needs of persons seeking HIV testing is scarce. Understanding the psychological health of persons seeking HIV testing and documenting how psychiatric symptoms develop over time following receipt of an HIV positive diagnosis, has important implications for mental health care systems.

Methods

We describe a study protocol to investigate: (1) the level of psychological distress and the prevalence of common mental disorders among persons seeking HIV testing; (2) the longitudinal development of psychiatric symptoms among persons diagnosed with HIV; and (3) the recommendations that can be made for mental health care systems to support persons seeking HIV testing and those newly diagnosed with HIV. In this longitudinal study quantitative and qualitative data are collected to document participants’ psychiatric symptoms, to determine whether they meet diagnostic criteria for a common mental disorder, and to explore the lived experiences of persons receiving an HIV positive test result. Data are collected at three time points; before HIV testing, and then again at 6 and 12 months post-testing.

Discussion

Documenting the prevalence of common mental disorders among persons seeking HIV testing, and tracking the psychosocial support needs, psychological adjustment and psychosocial experiences of persons newly diagnosed with HIV, has important implications for the delivery of mental health care services and the design of integrated mental health care systems.

Gender differences in health-related quality of life at the time of a positive HIV test - a cross-sectional study in a resource-poor, high prevalence setting in Nairobi, Kenya

Few studies have examined gender differences in sub-Saharan Africa, where HIV disproportionately affects women. Objectives of this cross-sectional study were to determine gender differences in HRQoL at the time of a positive HIV test, and whether factors associated with HRQoL differed between men and women. Adults testing HIV-positive were recruited from two clinics located in informal settlements. HRQoL was measured with the SF-12. Multiple linear regression was used to test whether there were gender differences in physical (PCS) and mental composite summary (MCS) scores. Separate models were built for men and women to examine factors associated with HRQoL. Between April 2013 and June 2015, 775 individuals from were recruited. The mean PCS score was higher in women (adjusted mean difference 2.49, 95% CI 0.54 to 4.44, p = 0.012). There was no significant gender difference in MCS scores. Similar factors were associated with better physical HRQoL in men and women: secondary education, younger age, higher CD4, and employment. Employment was the only factor associated with MCS in men, while less social support and low CD4 were associated with poorer MCS scores in women. Gender differences in factors related to HRQoL should be considered in broader policy and interventions to improve the HRQoL in those diagnosed with HIV.

Differences in health-related quality of life between HIV-positive and HIV-negative people in Zambia and South Africa: a cross-sectional baseline survey of the HPTN 071 (PopART) trial

BACKGROUND

The life expectancy of HIV-positive individuals receiving antiretroviral therapy (ART) is approaching that of HIV-negative people. However, little is known about how these populations compare in terms of health-related quality of life (HRQoL). We aimed to compare HRQoL between HIV-positive and HIV-negative people in Zambia and South Africa.

METHODS

As part of the HPTN 071 (PopART) study, data from adults aged 18-44 years were gathered between Nov 28, 2013, and March 31, 2015, in large cross-sectional surveys of random samples of the general population in 21 communities in Zambia and South Africa. HRQoL data were collected with a standardised generic measure of health across five domains. We used β-distributed multivariable models to analyse differences in HRQoL scores between HIV-negative and HIV-positive individuals who were unaware of their status; aware, but not in HIV care; in HIV care, but who had not initiated ART; on ART for less than 5 years; and on ART for 5 years or more. We included controls for sociodemographic variables, herpes simplex virus type-2 status, and recreational drug use.

FINDINGS

We obtained data for 19 750 respondents in Zambia and 18 941 respondents in South Africa. Laboratory-confirmed HIV status was available for 19 330 respondents in Zambia and 18 004 respondents in South Africa; 4128 (21%) of these 19 330 respondents in Zambia and 4012 (22%) of 18 004 respondents in South Africa had laboratory-confirmed HIV. We obtained complete HRQoL information for 19 637 respondents in Zambia and 18 429 respondents in South Africa. HRQoL scores did not differ significantly between individuals who had initiated ART more than 5 years previously and HIV-negative individuals, neither in Zambia (change in mean score -0·002, 95% CI -0·01 to 0·001; p=0·219) nor in South Africa (0·000, -0·002 to 0·003; p=0·939). However, scores did differ between HIV-positive individuals who had initiated ART less than 5 years previously and HIV-negative individuals in Zambia (-0·006, 95% CI -0·008 to -0·003; p<0·0001). A large proportion of people with clinically confirmed HIV were unaware of being HIV-positive (1768 [43%] of 4128 people in Zambia and 2026 [50%] of 4012 people in South Africa) and reported good HRQoL, with no significant differences from that of HIV-negative people (change in mean HRQoL score -0·001, 95% CI -0·003 to 0·001, p=0·216; and 0·001, -0·001 to 0·001, p=0·997, respectively). In South Africa, HRQoL scores were lower in HIV-positive individuals who were aware of their status but not enrolled in HIV care (change in mean HRQoL -0·004, 95% CI -0·01 to -0·001; p=0·010) and those in HIV care but not on ART (-0·008, -0·01 to -0·004; p=0·001) than in HIV-negative people, but the magnitudes of difference were small.

INTERPRETATION

ART is successful in helping to reduce inequalities in HRQoL between HIV-positive and HIV-negative individuals in this general population sample. These findings highlight the importance of improving awareness of HIV status and expanding ART to prevent losses in HRQoL that occur with untreated HIV progression. The gains in HRQoL after individuals initiate ART could be substantial when scaled up to the population level.

The REVAMP trial to evaluate HIV resistance testing in sub-Saharan Africa: a case study in clinical trial design in resource limited settings to optimize effectiveness and cost effectiveness estimates

BACKGROUND

In sub-Saharan Africa, rates of sustained HIV virologic suppression remain below international goals. HIV resistance testing, while common in resource-rich settings, has not gained traction due to concerns about cost and sustainability.

OBJECTIVE

We designed a randomized clinical trial to determine the feasibility, effectiveness, and cost-effectiveness of routine HIV resistance testing in sub-Saharan Africa.

APPROACH

We describe challenges common to intervention studies in resource-limited settings, and strategies used to address them, including: (1) optimizing generalizability and cost-effectiveness estimates to promote transition from study results to policy; (2) minimizing bias due to patient attrition; and (3) addressing ethical issues related to enrollment of pregnant women.

METHODS

The study randomizes people in Uganda and South Africa with virologic failure on first-line therapy to standard of care virologic monitoring or immediate resistance testing. To strengthen external validity, study procedures are conducted within publicly supported laboratory and clinical facilities using local staff. To optimize cost estimates, we collect primary data on quality of life and medical resource utilization. To minimize losses from observation, we collect locally relevant contact information, including Whatsapp account details, for field-based tracking of missing participants. Finally, pregnant women are followed with an adapted protocol which includes an increased visit frequency to minimize risk to them and their fetuses.

CONCLUSIONS

REVAMP is a pragammatic randomized clinical trial designed to test the effectiveness and cost-effectiveness of HIV resistance testing versus standard of care in sub-Saharan Africa. We anticipate the results will directly inform HIV policy in sub-Saharan Africa to optimize care for HIV-infected patients.

Depression and Engagement in Care Among Newly Diagnosed HIV-Infected Adults in Johannesburg, South Africa

Delayed engagement in HIV care threatens the success of HIV treatment programs in sub-Saharan Africa and may be influenced by depression. We examined the relationship between depression prior to HIV diagnosis and engagement in HIV care at a primary care clinic in Johannesburg, South Africa. We screened 1683 patients for depression prior to HIV testing using the Patient Health Questionnaire-9. Among patients who tested positive for HIV we assessed linkage to HIV care, defined as obtaining a CD4 count within 3 months. Among those who linked to care and were eligible for ART, we assessed ART initiation within 3 months. Multivariable Poisson regression with a robust variance estimator was used to assess the association between depression and linkage to care or ART initiation. The prevalence of HIV was 26 % (n = 340). Among HIV-infected participants, the prevalence of depression was 30 %. The proportion of linkage to care was 80 % among depressed patients and 73 % among patients who were not depressed (risk ratio 1.08; 95 % confidence interval 0.96, 1.23). Of the participants who linked to care, 81 % initiated ART within 3 months in both depressed and not depressed groups (risk ratio 0.99; 95 % confidence interval 0.86, 1.15). Depression was not associated with engagement in HIV care in this South African primary care setting. Our unexpected findings suggest that some depressed HIV-infected patients might be more likely to engage in care than their counterparts without depression, and highlight the complex relationship between depression and HIV infection. These findings have led us to propose a new framework relating HIV infection, depression, and the population under study.

The Prevalence of Common Mental Disorders Among South Africans Seeking HIV Testing

We administered the Structured Clinical Interview for the DSM to 485 persons seeking HIV testing at five community testing centres in South Africa to determine the prevalence of common mental disorders among this population. The prevalence estimates for the various disorders were as follows: major depressive disorder: 14.2 % (95 % CI [11.1, 17.3]); generalised anxiety disorder 5.0 % (95 % CI [3.07, 6.93]); posttraumatic stress disorder 4.9 % (95 % CI [2.98, 6.82]); and alcohol use disorder 19.8 % (95 % CI [16.26, 23.34]). Our findings imply the need to research the integration of screening and referral trajectories in the context of voluntary HIV counselling and testing.

Depression with pain co morbidity effect on quality of life among HIV positive patients in Uganda: a cross sectional study

Background

Depression with pain comorbidity (DPC) has not been clearly defined among HIV positive patients in sub-Saharan Africa. It still remains a challenge despite many studies in Africa documenting a high prevalence of pain and depression among people living with HIV/AIDS. Both are associated with a grave impact on the health related outcomes in this pandemic. This study aimed at determining the prevalence, factors associated and effect on quality of life of DPC among HIV positive patients.

Methods

In a cross-sectional survey, 345 HIV positive patients were enrolled into the study. Using a pre-tested standardised questionnaire the presence of DPC was assessed after a written informed consent. The associations between DPC, quality of life, depression history, severity, and cognition were determined. A p-value of <0.05 was considered to be significant.

Results

Among people living with HIV/AIDS (PLWHA), the prevalence of DPC was about 5 %. PLWHA with DPC were more likely to perceive their overall quality of life as poor and scored poorly in all the domains on the WHOQOL-BREF. They were also more likely to have more severe forms of depression and recurrent episodes of depression.

Conclusions

DPC is common, under diagnosed and undertreated in PLWHA in Uganda. Depression and pain screening as well as appropriate access to care for DPC have potential to improve quality of life and health outcomes. This calls for the integration and training of mental health services into HIV/AIDS care and future efforts by policy makers and HIV caregivers to address this treatment gap to advance the care of people living with HIV in Uganda.

Psychiatric disorders and adherence to antiretroviral therapy among a population of HIV-infected adults in Nigeria

Psychiatric disorders are common among people living with HIV in Nigeria. Adherence is necessary to optimise the outcome of antiretroviral therapy. In this study, we aimed to identify associations between antiretroviral adherence, measured by one-week and one-month self-reported missed doses, and psychiatric illness in a cohort previously assessed for psychiatric disorders using the Composite International Diagnostic Interview. The study participants comprised 151 adults with major depression, anxiety or suicidal symptoms, and 302 matched-control participants. Two controls were randomly selected for each case within the same gender and education level. We compared participants with psychiatric disorders (WPDs) and no psychiatric disorders (NPDs) on selected demographic and clinical variables, in addition to adherence. Participants with one or more missed doses in the preceding month had twice the odds of having a major depressive episode as those with no missed doses during this period (OR 2.22, 95% CI 1.03, 4.79). This association remained significant after adjusting for selected risk factors. There was no statistically significant difference between WPD and NPD groups on either one-week or one-month adherence, or on age, marital status, occupational class, HIV viral load at enrolment or current CD4 cell count. Among Nigerian adults with HIV, suboptimal antiretroviral adherence is associated with, and could be a sign of, depression. Routine self-report adherence assessments may potentially be utilised in identifying individuals at risk among this population.

Improving Health-Related Quality of Life among People Living with HIV: Results from an Impact Evaluation of a Food Assistance Program in Uganda

Introduction

Widespread food insecurity in Africa continues to compromise an effective response to the AIDS epidemic. Health-related quality of life (HRQoL) is a comprehensive indicator of physical, mental, and social well-being that is associated with food insecurity and increasingly used to assess the well-being of people living with HIV/AIDS (PLHIV). We examined the impact of a food assistance intervention, previously shown to have reduced household food insecurity and improved nutritional status, on HRQoL of PLHIV.

Methods

We capitalized on an existing intervention targeting antiretroviral therapy (ART)- naïve PLHIV in Uganda, and conducted a prospective impact evaluation including a treatment and a comparison group. Data analyzed included 640 participants from two districts (318 in the intervention district) interviewed in both clinic and household settings at baseline and again approximately one year later. The main outcomes considered were physical and mental health dimensions of HRQoL, and other outcomes included self- and healthcare provider-reported symptoms. We utilized difference-in-difference propensity score matching methodologies to infer causality and examine program impacts.

Results

Over 12 months, food assistance significantly increased physical health scores (PHS) by 2.85 (P < .01) or approximately 0.35 SD, and reduced substantially the number of self- and healthcare provider-reported HIV-related symptoms by 3.83 and 2.68, respectively (P < .01). There was no significant impact, however, on mental health scores (MHS).

Conclusions

This study demonstrates the potential importance for HRQoL of including food assistance programming as part of the standard of care for PLHIV in areas of widespread food insecurity.

An Educational Intervention to Reduce Pain and Improve Pain Management for Malawian People Living With HIV/AIDS and Their Family Carers: A Randomized Controlled Trial

CONTEXT

Advances being made in improving access to HIV drugs in resource-poor countries mean HIV patients are living longer, and, therefore, experiencing pain over a longer period of time. There is a need to provide effective interventions for alleviating and managing pain.

OBJECTIVES

To assess whether a pain educational intervention compared with usual care reduces pain severity and improves pain management in patients with HIV/AIDS and their family carers.

METHODS

This was a randomized, parallel group, superiority trial conducted at HIV and palliative care clinics of two public hospitals in Malawi. A total of 182 adults with HIV/AIDS (Stage III or IV) and their family carers participated; carer participants were those individuals most involved in the patient's unpaid care. The educational intervention comprised a 30 minute face-to-face meeting, a leaflet, and a follow-up telephone call at two weeks. The content of the educational intervention covered definition, causes, and characteristics of pain in HIV/AIDS; beliefs and myths about pain and pain medication; assessment of pain; and pharmacological and nonpharmacological management. The primary outcome was average pain severity measured by the Brief Pain Inventory-Pain Severity subscale. Assessments were recorded at baseline before randomization and at eight weeks after randomization.

RESULTS

Of the 182 patient/carer dyads randomly allocated, 157 patient/carer dyads completed the trial. Patients in the intervention group experienced a greater decrease in pain severity (mean difference = 21.09 points, 95% confidence interval = 16.56-25.63; P < 0.001).

CONCLUSION

A short pain education intervention is effective in reducing pain and improving pain management for Malawian people living with HIV/AIDS and their family carers.

The need for a Rehabilitation Model to address the disparities of public healthcare for people living with HIV in South Africa

Rehabilitation in the context of HIV management in Africa is still a neglected field which holds great promise for the improvement of the quality of life as well as integration of people living with HIV back into their communities and homes. However, rehabilitation has not been incorporated into HIV care despite the fact that a large number of people living with HIV experience disability. The dearth of literature and lack of models of care to roll out rehabilitation for people living with HIV in Africa are astounding. Well-resourced countries have emerging approaches on the management of disability in the context of HIV. However, epidemic countries are still lacking such an approach neglecting the devastating effects of disability on individual livelihoods and antiretroviral treatment adherence. Thus, rehabilitation needs to be integrated into the response to HIV. This article advocates for the development and implementation of a model of care to guide rehabilitation of people living with HIV in South Africa.

Social support as a protective factor for depression among women caring for children in HIV-endemic South Africa

Social support has been shown to be a protective resource for mental health among chronically ill adults and caregiver populations. However, to date no known studies have quantitatively explored the relationship between social support and depression among women caring for children in HIV-endemic Southern Africa, although they represent a high risk population for mental health conditions. Using data from a household survey with 2,199 adult female caregivers of children, living in two resource-deprived high HIV-prevalence South African communities, we conducted hierarchical logistic regression analysis with interaction terms to assess whether social support had a main effect or stress-buffering effect on depression. Findings provide evidence of stress-buffering of non-HIV-related chronic illness, but not HIV-related illness. Results reinforce the importance of social support for the mental health of chronically ill caregivers, and suggest that factors related to the specific nature of HIV/AIDS may be hindering the potential stress-buffering effects of social support among people living with the disease. Implications for future research and interventions are discussed.

Longitudinal and cross sectional assessments of health utility in adults with HIV/AIDS: a systematic review and meta-analysis

Background

Utility estimates are important health outcomes for economic evaluation of care and treatment interventions for patients with HIV/AIDS. We conducted a systematic review and meta-analysis of utility measurements to examine the performance of preference-based instruments, estimate health utility of patients with HIV/AIDS by disease stages, and investigate changes in their health utility over the course of antiretroviral treatment.

Methods

We searched PubMed/Medline, Cochrane Database of Systematic Review, NHS Economic Evaluation Database and Web of Science for English-language peer-reviewed papers published during 2000–2013. We selected 49 studies that used 3 direct and 6 indirect preference based instruments to make a total of 218 utility measurements. Random effect models with robust estimation of standard errors and multivariate fractional polynomial regression were used to obtain the pooled estimates of utility and model their trends.

Results

Reliability of direct-preference measures tended to be lower than other types of measures. Utility elicited by two of the indirect preference measures - SF-6D (0.171) and EQ-5D (0.114), and that of Time-Trade off (TTO) (0.151) was significantly different than utility elicited by Standard Gamble (SG). Compared to asymptomatic HIV patients, symptomatic and AIDS patients reported a decrement of 0.025 (p&#×2009;=&#×2009;0.40) and 0.176 (p&#×2009;=&#×2009;0.001) in utility scores, adjusting for method of assessment. In longitudinal studies, the pooled health utility of HIV/AIDS patients significantly decreased in the first 3 months of treatment, and rapidly increased afterwards. Magnitude of change varied depending on the method of assessment and length of antiretroviral treatment.

Conclusion

The study provides an accumulation of evidence on measurement properties of health utility estimates that can help inform the selection of instruments for future studies. The pooled estimates of health utilities and their trends are useful in economic evaluation and policy modelling of HIV/AIDS treatment strategies.

The importance of family and community support for the health of HIV-affected populations in Southern Africa: what do we know and where to from here?

PURPOSE

Informal family and community support deriving from social relations can play an important role in protecting mental and physical health in resource-scarce contexts and may help facilitate health service access and uptake. Yet, to date, there has been surprisingly little empirical research investigating the role of social support as a resource for health in HIV-affected Southern African communities, despite the known importance of social connectedness, high rates of physical and mental health conditions, and existing 'treatment gaps'.

METHODS

This paper brings together and discusses findings of multiple linked analyses, from the first large-scale explanatory sequential mixed methods research investigating the relationship between social support and health with caregiver populations in HIV-endemic South Africa.

RESULTS

Overall, findings highlight the protective role of social support for caregiver mental health, the multiple perceived psychological and behavioural mechanisms possibly explaining the relationship between social support and both mental and physical health, and gender differences in the provision, effects, and availability of support.

CONCLUSIONS

Drawing from these findings and the broader literature, four potential foci for future research in Southern Africa are identified and discussed, as are implications for research design and methodologies. These involve achieving a better understanding of the following: The pathways and processes explaining common and differential effects of social support across different population groups; the potential protective role of social support for physical health; and the role of factors such as gender and social and cultural norms in shaping the relationship between social support and health. Statement of contribution What is already known on this subject? Mental and physical health are closely related. HIV increases the risk of mental health conditions. Studies mainly from high-income countries have shown social relations and support to be protective of health. What does this study add? First mixed methods research of this dimension on social support and health in Southern Africa. Highlights importance of social support for mental health among caregivers of children in HIV-endemic South Africa. Points to biological and psychological pathways explaining the support-health relationship in this sample.

Development of a Model of Care for Rehabilitation of People Living With HIV in a Semirural Setting in South Africa

Background

Human immunodeficiency virus continues to challenge health care professionals even after the rollout of antiretroviral therapy. South Africa, among the worst affected countries in the world by the pandemic, has seen the effect of people living longer but facing disabling effects of both the virus and the associated impairments of the antiretroviral therapy. Rehabilitation within the evolving context of the disease has changed its focus from the impairment of the individual to the participation restriction within a person’s daily life. Offering a continuum of coordinated, multilevel, multidiscipline, evidence-based rehabilitation within health care will promote its prominence in health care structures.

Objective

This study aims to develop a model of care within a health care structure using a semi-rural African setting as an example.

Methods

The study will employ mixed methods using a Learning in Action Approach into the rehabilitation of people living with HIV (PLHIV) at the study setting. The Delphi technique, a multistage consensus method, will be used to obtain feedback from a number of local experts relevant for the field of rehabilitation of people living with HIV. The study will also involve various stakeholders such as the multidisciplinary health care team (doctors, physiotherapists, occupational therapists, dieticians, speech and language therapists, social workers, midlevel workers, community health care workers); department of health representative(s); site affiliated nongovernmental organization representative(s); and service users at the study setting.

Results

Once a proposed model of care is derived, the model will be assessed for rigour and piloted at the study setting.

Conclusions

The development of a model of care in rehabilitation for PLHIV in a health care setting is aimed to provide an example of a continuum of coordinated service throughout the disease trajectory. The assumption is that the burden on the health care system will be curbed and the projected benefit for all stakeholders will promote a sort after service delivery in rehabilitation of people living with HIV.

Health-related quality of life of patients six months poststroke living in the Western Cape, South Africa

Background

The majority of individuals report a decline in health-related quality of life following a stroke. Quality of life and factors predicting quality of life could differ in individuals from lower income countries. The aim of this study was therefore to determine the quality of life and factors influencing quality of life of community-dwelling stroke patients living in low-income, peri-urban areas in the Western Cape, South Africa.

Method

An observational, longitudinal study was used to collect data from a conveniently selected sample of first-ever stroke patients. The Rivermead Motor Assessment Scale and the Barthel Index were used to determine functional outcome and the EQ-5D was used to collect information relating to quality of life at two months and six months poststroke. Descriptive and inferential statistics were used to analyse the data.

Results

The total sample of 100 participants consisted of 50% men and 50% women with a mean age of 61 and a standard deviation of 10.55 years. Six-month quality of life data was analysed for 73 of the 100 participants. Of the 27 who were lost to follow-up, nine participants died, four withdrew from the study after baseline data was collected and eleven could not be followed up as they had either moved or no follow-up telephone numbers were available. A further three participants were excluded from the analysis of the EQ-5D as they were aphasic. Of these, approximately 35% had problems with mobility and self-care, whilst 42% had severe problems with everyday activities and 37.8% expressed having anxiety and depression. Quality of life at two months (p = 0.010) and urinary incontinence (p = 0.002) were significant predictors of quality of life at six months.

Conclusion

Health-related quality of life was decreased in the South African stroke sample. Functional ability and urinary incontinence were the factors affecting quality of life in the sample. These factors should be considered in the rehabilitation of stroke patients in these settings.

A comparison of quality of life between HIV positive and negative diamond miners in South Africa

Objective

To analyse the health-related quality of life (HR-QOL) in two groups of diamond miners (HIV negative and positive) in South Africa using three instruments. Two hypotheses were to be tested. One, was that the HR-QOL of HIV positive miners would be lower than that of HIV negative miners; and two, the selected instruments would behave consistently and thus all would confirm hypothesis one.

Methods

In our study, workers were recruited during a voluntary counselling and testing programme for HIV. HR-QOL were estimated using the Assessment of Quality of Life (AQOL) Mark 2, EQ-5D (EuroQOL), and Health Utilities Index 3 (HUI3) instruments. The data were analysed for utility values and for correlations between variables of interest (in particular HIV status). Goodness of fit, Pearson's r coefficient and t-tests were the statistical tests applied to the data.

Results

Just over 1100 respondents were included in the analysis. HIV positive workers scored significantly lower on quality of life on the HUI3 as compared to HIV negative workers but this relationship did not (surprisingly) hold for the AQOL or EQ-5D. There was a significant positive correlation between all three instruments.

Conclusion

There was inconsistency among the instruments in measuring quality of life differences according to HIV status. The HUI3 confirmed the a priori expectation that the HR-QOL of HIV positive miners would be lower than HIV negative miners. There was no statistical difference for the AQOL and a confounding result was found for the EQ5D.

The impact of comorbid clinical depression on the health-related quality of life of adults on highly active antiretroviral therapy in maiduguri, northeastern Nigeria

BACKGROUND

Globally, depression compromises the quality of life (QOL) of people suffering from it. We assessed the impact of comorbid depression on the health-related quality of life (HRQOL) of adults on highly active antiretroviral therapy (HAART) in northeastern Nigeria in this study.

MATERIALS AND METHODS

Three hundred and three adults on HAART were recruited for this study from the ART clinic of the University of Maiduguri Teaching Hospital in northeastern Nigeria. The depressive disorder module of the Composite international diagnostic interview (CIDI version 3.0) and the WHO quality of life instrument (WHOQOL-BREF) were used for the evaluation of depression and quality of life respectively.

RESULTS

The prevalence of depression in this study was 19.8%. The depressed respondents rated their HRQOL poorer than their nondepressed counterparts on the physical, psychological, social relationships and environmental domains as well as the global outcome, as shown by these statistically significant findings (T = 9.739, P = <0.001), (T = 8.972, P = <0.001), (T = 6.533, P = <0.001), (T = 8.913, P = <0.001), and (T = 10.018, P = <0.001), respectively. Female gender, CD4 counts <200/mm(3) and diagnosis of depression were significant predictors poor QOL.

CONCLUSION

Depression has a negative impact on the QOL of the respondents. We therefore recommend incorporation of the routine screening of this important psychiatric comorbidity into the care of this vulnerable group in order to optimize patient care.

Validity of the Patient Health Questionnaire-9 to screen for depression in a high-HIV burden primary healthcare clinic in Johannesburg, South Africa

BACKGROUND

Integration of depression screening into primary care may increase access to mental health services in sub-Saharan Africa, but this approach requires validated screening instruments. We sought to validate the Patient Health Questionnaire-9 (PHQ-9) as a depression screening tool at a high HIV-burden primary care clinic in Johannesburg, South Africa.

METHODS

We conducted a validation study of an interviewer-administered PHQ-9 among 397 patients. Sensitivity and specificity of the PHQ-9 were calculated with the Mini International Neuropsychiatric Interview (MINI) as the reference standard; receiver operating characteristic (ROC) curve analyses were performed.

RESULTS

The prevalence of depression was 11.8%. One-third of participants tested positive for HIV. HIV-infected patients were more likely to be depressed (15%) than uninfected patients (9%; p=0.08). Using the standard cutoff score of ≥10, the PHQ-9 had a sensitivity of 78.7% (95% CI: 64.3-89.3) and specificity of 83.4% (95% CI: 79.1-87.2). The area under the ROC curve was 0.88 (95% CI: 0.83-0.92). Test performance did not vary by HIV status or language. In sensitivity analyses, reference test bias associated with the MINI appeared unlikely.

LIMITATIONS

We were unable to conduct qualitative work to adapt the PHQ-9 to this cultural context.

CONCLUSION

This is the first validation study of the PHQ-9 in a primary care clinic in sub-Saharan Africa. It highlights the potential for using primary care as an access point for identifying depressive symptoms during routine HIV testing. The PHQ-9 showed reasonable accuracy in classifying cases of depression, was easily implemented by lay health workers, and is a useful screening tool in this setting.

Mental health of carers of children affected by HIV attending community-based programmes in South Africa and Malawi

There is strong evidence that both adults and children infected with and affected by HIV have high levels of mental health burden. Yet there have been few studies investigating carer mental health outcomes in the context of HIV in Malawi and South Africa. The objective of this study was to assess the mental health of carers of children affected by HIV as a part of the Child Community Care study, which aims to generate evidence on the effectiveness of community-based organisation (CBO) services to improve child outcomes. In a cross-sectional study, we interviewed 952 carers of children (aged 4-13 years) attending 28 randomly selected CBOs funded by 11 major donors in South Africa and Malawi. Psychological morbidity was measured using the Shona Symptom Questionnaire and suicidal ideation was measured using an item from the Patient Health Questionnaire. Carers were asked about care-seeking for emotional problems. Overall, 28% of carers scored above the clinical cut-off for current psychological morbidity and 12.2% reported suicidal ideation. We used logistic regression models to test factors associated with poor outcomes. Household unemployment, living with a sick family member and perceived lack of support from the community were associated with both psychological morbidity and suicidal ideation in carers. Reported child food insecurity was also associated with psychological morbidity. In addition, carers living in South Africa were more likely to present with psychological morbidity and suicidal ideation than carers in Malawi. Rates of help-seeking for mental health problems were low. Carers of children affected by HIV are at risk for mental health problems as a result of HIV, socio-economic, care-giving and community factors. We call for increased recognition of the potential role of CBOs in providing mental health care and support for families as a means to improve equity in mental health care. Specifically, we highlight the need for increased training and supervision of staff at CBOs for children affected by HIV, and the inclusion of CBOs in broader efforts to improve population mental health outcomes.

Pain in people living with HIV/AIDS: a systematic review

INTRODUCTION

Pain is one of the most commonly reported symptoms in people living with HIV/AIDS (PLWHA). However, wide ranges of pain prevalence have been reported, making it difficult to determine the relative impact of pain in PLWHA. A systematic review of the literature was conducted to establish the prevalence and characteristics of pain and to explore pain management in PLWHA.

METHODS

Studies that included cross-sectional data were included in the search, which was conducted in April 2012. Databases searched using a time limit of March 1982 to March 2012 included PubMed, Scopus, Africa-wide: NIPAD, CINAHL, PsychARTICLES, PSYCINFO, PSYCHIATRYONLINE, ScienceDirect and Web of Science. Search terms selected were "pain" and "HIV" or "acquired immune deficiency syndrome." Two reviewers independently screened all citation abstracts for inclusion. Methodological quality was evaluated using a standardized 11-item critical appraisal tool.

RESULTS

After full text review, 61 studies fulfilled the inclusion criteria. Prevalence of pain ranged from a point prevalence of 54% (95%CI 51.14-56.09) to 83% (95%CI 76-88) using a three-month recall period. The reported pain was of moderate-to-severe intensity, and pain was reported in one to two and a half different anatomical sites. Moderate levels of pain interference with function were reported. All nine studies reporting on the adequacy of pain management recorded marked under-treatment of pain.

DISCUSSION

The studies reviewed reported that pain commonly presents at multiple pain sites with a range of severity suggesting that there are several differing pathological processes contributing to pain at one time. The interplay of variables associated with pain suggests that the biopsychosocial model of pain is an appropriate paradigm from which to view pain in PLWHA and from which to approach the problem, explore causes and establish effective treatment.

CONCLUSIONS

The results highlight that pain is common in PLWHA at all stages of the disease. The prevalence rates for pain in PLWHA do not appear to have diminished over the 30 years spanning the studies reviewed. The body of work available in the literature thus far, while emphasizing the problem of pain, has not had an impact on its management.

Quality of life amongst young adults with stroke living in Kenya

BACKGROUND

The world has been experiencing an increase of stroke among young adults. Occurrence of stroke in young adults dramatically affects the quality of life of the individuals.

OBJECTIVES

To investigate the quality of life amongst young adults who experienced a stroke living in Kenya.

METHODS

A cross-sectional study was carried out on a conveniently selected sample of 161 young adults with stroke drawn from three tertiary hospitals in Kenya. The Short-Form 36-item second version (SF-36v2) was used to collect the data. Descriptive and association statistical analysis using Mann-Whitney U, and Kruskal Wallis tests were calculated on the data using SPSS.

RESULTS

In relation to a total score of 100, when expressed as a percentage the mean quality of life scores, ranged from 30% to 48% for each of the SF-36v2 domains. The results showed that males scored higher than females in all the domains except in physical functioning and that the scores decline with advance in age in most domains.

CONCLUSION

The quality of life scores for this group were low meaning that that they were experiencing more challenges with physical functioning, psychological and emotional functioning and fulfilling previous roles.

An educational intervention to reduce pain and improve pain management for Malawian people living with HIV/AIDS and their family carers: study protocol for a randomised controlled trial

Background

Many HIV/AIDS patients experience pain often due to advanced HIV/AIDS infection and side effects of treatment. In sub-Saharan Africa, pain management for people with HIV/AIDS is suboptimal. With survival extended as a direct consequence of improved access to antiretroviral therapy, the prevalence of HIV/AIDS related pain is increasing. As most care is provided at home, the management of pain requires patient and family involvement. Pain education is an important aspect in the management of pain in HIV/AIDS patients. Studies of the effectiveness of pain education interventions for people with HIV/AIDS have been conducted almost exclusively in western countries.

Methods/design

A randomised controlled trial is being conducted at the HIV and palliative care clinics of two public hospitals in Malawi. To be eligible, patient participants must have a diagnosis of HIV/AIDS (stage III or IV). Carer participants must be the individual most involved in the patient’s unpaid care. Eligible participants are randomised to either: (1) a 30-minute face-to-face educational intervention covering pain assessment and management, augmented by a leaflet and follow-up telephone call at two weeks; or (2) usual care. Those allocated to the usual care group receive the educational intervention after follow-up assessments have been conducted (wait-list control group). The primary outcome is pain severity measured by the Brief Pain Inventory. Secondary outcomes are pain interference, patient knowledge of pain management, patient quality of life, carer knowledge of pain management, caregiver motivation and carer quality of life. Follow-up assessments are conducted eight weeks after randomisation by palliative care nurses blind to allocation.

Discussion

This randomised controlled trial conducted in sub-Saharan Africa among people living with HIV/AIDS and their carers will assess whether a pain education intervention is effective in reducing pain and improving pain management, quality of life and carer motivation.

Comparison of the health-related quality of life, CD4 count and viral load of AIDS patients and people with HIV who have been on treatment for 12 months in rural South Africa

This study compared the level of CD4 count, viral load and health-related quality of life (HRQOL) between treatment-naïve AIDS patients and a cohort of people living with HIV who have been on treatment for 12 months. This study is based on a secondary data analysis of the records of 642 people with HIV consisting of 311 treatment-naïve AIDS patients and 331 people with HIV who have been on treatment for 12 months. The study findings are mostly presented in tables and analysed using the t-test to compare HRQOL scores, CD4 count and viral load in the two groups. The study generally noted poor financial capacity and low activity tolerance among the participants. Significant changes were noted in all the domains of HRQOL compared between the treatment-naïve patients and the 12 months treatment cohort. In the same manner, the median CD4 cell count and viral load differed significantly between both groups. The treatment-naïve and the 12 months treatment cohorts consistently reported much lower quality of life scores in the level of dependence domain which includes the measures of mobility, activity of daily living, dependence on medication and work capacity. There were little or no associations between the biomedical markers (CD4 count and viral load) and HRQOL indicators. However, the quality of life tended to increase with increase in the CD4 cell count. The poor to no association between the biomedical markers and HRQOL indicators show that these cannot be direct proxies of each other and that the CD4 cell count and viral load alone may be inadequate eligibility criteria for social support.

Food access and diet quality are associated with quality of life outcomes among HIV-infected individuals in Uganda

Background

Food insecurity is associated with poor nutritional and clinical outcomes among people living with HIV/AIDS. Few studies investigate the link between food insecurity, dietary diversity and health-related quality of life among people living with HIV/AIDS.

Objective

We investigated whether household food access and individual dietary diversity are associated with health-related quality of life among people living with HIV/AIDS in Uganda.

Methods

We surveyed 902 people living with HIV/AIDS and their households from two clinics in Northern Uganda. Health-related quality of life outcomes were assessed using the Medical Outcomes Study (MOS)-HIV Survey. We performed multivariate regressions to investigate the relationship between health-related quality of life, household food insecurity and individual dietary diversity.

Results

People living with HIV/AIDS from severe food insecurity households have mean mental health status scores that are 1.7 points lower (p<.001) and physical health status scores that are 1.5 points lower (p<.01). Individuals with high dietary diversity have mean mental health status scores that were 3.6 points higher (p<.001) and physical health status scores that were 2.8 points higher (p<.05).

Conclusions

Food access and diet quality are associated with health-related quality of life and may be considered as part of comprehensive interventions designed to mitigate psychosocial consequences of HIV.

Health-related quality of life 'well-being' in HIV distal neuropathic pain is more strongly associated with depression severity than with pain intensity

BACKGROUND

Despite modern antiretroviral treatment, HIV-associated distal neuropathic pain (DNP) remains one of the most prevalent and debilitating complications of HIV disease. Neuropathic pain is often accompanied by depressed mood, and both pain and depression have been associated with decreased health-related quality of life (HRQOL) well-being. The relative contribution of depression and pain to worse life quality has not been addressed, however, even though a better understanding might sharpen intervention strategies.

METHODS

We used the Medical Outcomes Study HIV (MOS-HIV) Health Survey and the Beck depression inventory-II and linear regression models to investigate HRQOL well-being in HIV-infected patients with DNP (n = 397) participating in an observational cohort study at six U.S. sites (CNS HIV Antiretroviral Treatment Effects Research Study, CHARTER).

RESULTS

For this sample of patients with HIV DNP, severity of depressed mood was more highly correlated with HRQOL well-being than was pain intensity.

CONCLUSIONS

These results suggest that interventions to improve HRQOL well-being in individuals with HIV-associated DNP may need to address not only pain intensity but mood state as well.

Pain in ambulatory HIV-positive South Africans

We investigated the prevalence and intensity of pain, factors associated with having pain, and analgesic medications employed in a population consisting predominantly of Black African and female human immunodeficiency virus (HIV)-positive individuals attending outpatient clinics in a rural (n = 125; 79% female; 100% Black African) and a metropolitan (n = 396; 75% female; 94% Black African) area of South Africa. Pain intensity, interference and treatment were assessed using the Wisconsin Brief Pain Questionnaire. Seventy-two percent of rural participants and 56% of metropolitan participants had pain at the time of the interview, and this pain was moderate to severe in intensity in 60% of rural participants and 59% of metropolitan participants. Forty-six percent of rural participants and 61% of metropolitan participants had multiple pain sites. The most common pain sites in rural participants were the abdomen (30%), chest (26%), head (19%) and genitals (15%), while in the metropolitan cohort the head (39%), feet (33%), chest (30%) and abdomen (20%) were the most common sites. In the rural cohort, antiretroviral therapy was independently associated with reduced risk of pain, while in the metropolitan cohort increasing age was weakly, but independently associated with having pain. Pharmacological management of pain was poor, with 29% of rural participants and 55% of metropolitan participants with pain not receiving any treatment. Of those receiving treatment, no participants were receiving strong opioids, and only 3% of metropolitan participants were receiving a weak opioid. Thus, HIV-related pain is common and is poorly treated in both the rural and metropolitan setting in South Africa.

Quality of life and its determinants in people living with human immunodeficiency virus infection in puducherry, India

CONTEXT

With anti-retroviral therapy (ART) for human immunodeficiency virus infection (HIV) coming into picture, quality of life (QOL) has gained importance. Knowledge on the factors affecting QOL would be helpful in making important policy decisions and health care interventions.

AIMS

The aim of this study is to assess the quality of life of people living with HIV (PLWH) and to identify the factors influencing their QOL.

MATERIALS AND METHODS

The study was done among 200 PLWH attending a tertiary care hospital, and three Non Governmental Organizations at Puducherry, India, from November 2005 to May 2007. QOL was assessed using HIV specific World Health Organization Quality Of Life scale (WHOQOL-HIV) - BREF questionnaire which has six domains (physical, psychological, level of independence, social relationships, environment and spirituality/religiousness/personal belief). Social support and stigma were measured using "Multidimensional Scale of Perceived Social Support" and "HIV Stigma Scale," respectively, using Likert Scale. Factors influencing QOL were identified using backward stepwise multiple linear regression with the six domain scores as the dependent variables.

RESULTS

MALE: Female ratio was 1:1 and 58% were in early stage of the disease (stage I/II). Psychological and SRPB (Spirituality Religiousness and Personal Beliefs) domains were the most affected domains. All the regression models were statistically significant (P<0.05). The determination coefficient was highest for the social relationship domain (57%) followed by the psychological domain (51%). Disease stage and perceived social support significantly influenced all the domains of WHOQOL. Younger age, female gender, rural background, shorter duration of HIV, non-intake of ART and greater HIV related stigma were the high risk factors of poor QOL.

CONCLUSION

Interventions such as ART, family, vocational and peer counseling would address these modifiable factors influencing QOL, thereby improving the QOL of PLWH.

Current perspectives on HIV-related pain and its management: insights from sub-Saharan Africa

SUMMARY Sub-Saharan Africa is the region worst affected by the HIV epidemic and we estimate that at least 10 million HIV-positive individuals in sub-Saharan Africa live with significant pain related to their disease. Until recently there was a lack of studies specifically addressing pain related to HIV infection in sub-Saharan Africa, which limited our understanding of the scope of the problem. Here we describe the current nature of the epidemic of HIV-related pain in sub-Saharan Africa, including the systematic under-recognition and undertreatment of the pain.

Safety considerations in drug treatment of depression in HIV-positive patients: an updated review

Major depressive disorder (MDD) is one of the most prevalent illnesses associated with HIV infection, and negatively affects medication adherence, disease progression and mortality in HIV disease. Co-morbid treatment of major depression in HIV disease is the optimal therapeutic approach, but discriminating MDD from normal fluctuations in mood state, personality or physiology is difficult. Definitive diagnosis of MDD is critical for drug safety and for avoiding unnecessary exposure to psychotropic medications. HIV patients respond to antidepressant treatment like the general population, and medication adverse effects and patient adherence are the best predictors of treatment outcome. This review attempts to assist the medical provider with the diagnosis and treatment of MDD in HIV patients. We outline the initial steps in screening and psychiatric referral, the antidepressants that are particularly useful in HIV-infected patients, and the adverse effects and pharmacological strategies for overcoming potential barriers to medication adherence. Potential interactions between the various classes of antidepressants and HIV/antiretroviral therapy, as well as management of HIV medication-related psychiatric adverse effects, are also discussed.
