Trauma, stressful life events and depression predict HIV-related fatigue

Depression during the COVID-19 pandemic among people living with HIV: Are low HIV/AIDS stigma and high perceived emotional support protective resources?

This study has two objectives: first, to examine changes in depressive symptoms among people living with HIV (PLWH) during the COVID-19 pandemic and, second, to verify the role of HIV/AIDS stigma and perceived emotional support (PES) in the heterogeneity of these changes. The participants were 392 people with a medical diagnosis of HIV who have undergone antiretroviral therapy. Depression was measured at three time points with 6-month intervals using the Centre for Epidemiological Studies Depression Scale (CES-D). PES was evaluated with the Berlin Social Support Scales, and HIV/AIDS-related stigma was assessed with the Berger HIV Stigma Scale. Latent growth class modelling identified four trajectories of depression over the study period: three stable (very high, high, and very low) and one increasing. Both the very high and high stable trajectories had baseline values above the CES-D cut-off point for depression, suggesting that 57.6% of the sample was likely to be diagnosed with depression. After controlling for sociodemographic and clinical variables, stigma and PES were found to be significant covariates of the obtained trajectories; however, they did not protect against an increase in depression symptoms. There was no overall increase in depression symptoms among the PLWH participants during the pandemic, but this change in depression symptoms was heterogeneous. We observed the potential development of depression in initially well-functioning individuals despite their personal resources differing only slightly from those who remained resilient.

Stressful Life Events and Chronic Fatigue Among Chinese Government Employees: A Population-Based Cohort Study

Background

Currently, evidence on the role of stressful life events in fatigue among the Chinese working adults is lacking. This study aimed at exploring the prospective associations between stressful life events and chronic fatigue among Chinese government employees.

Methods

From January 2018 to December 2019, a total of 16206 government employees were included at baseline and they were followed-up until May 2021. A digital self-reported questionnaire platform was established to collect information on participants' health and covariates. Life events were assessed by the Life Events Scale (LES), fatigue was assessed by using a single item, measuring the frequency of its occurrence. Binary logistic regression analysis was used for the data analysis.

Results

Of the included 16206 Chinese government employees at baseline, 60.45% reported that they experienced negative stressful life events and 43.87% reported that they experienced positive stressful life events over the past year. Fatigue was reported by 7.74% of the sample at baseline and 8.19% at follow-up. Cumulative number of life events at baseline, and cumulative life events severity score at baseline were positively associated with self-reported fatigue at follow up, respectively. After adjusting sociodemographic factors, occupational factors and health behavior related factors, negative life events at baseline (OR: 2.06, 95% CI: 1.69–2.51) were significantly associated with self-reported fatigue at follow-up. Some specific life events including events related to work and events related to economic problems were significantly associated with self-reported fatigue. Specifically, work stress (OR = 1.76, 95%CI: 1.45–2.13), as well as not satisfied with the current job (OR = 1.95, 95%CI: 1.58–2.40), in debt (OR = 1.75, 95%CI: 1.40–2.17) were significantly associated with self-reported fatigue. The economic situation has improved significantly (OR = 0.62, 95%CI: 0.46–0.85) at baseline was significantly associated with lower incidence of self-reported fatigue.

Conclusion

Negative stressful life events were associated with fatigue among Chinese government employees. Effective interventions should be provided to employees who have experienced negative stressful life events.

Prevalence of stressful life events and associations with symptoms of depression, anxiety, and post-traumatic stress disorder among people entering care for HIV in Cameroon

BACKGROUND

Exposure to stressors increases the risk of mental health disorders. People living with HIV (PLWH) are particularly affected by poor mental health which can contribute to adverse HIV treatment outcomes.

METHODS

We estimated the prevalence of recent stressful life events (modified Life Events Survey) among a cohort of PLWH entering HIV care at three public health care facilities in Cameroon and quantified the association of seven types of stressful life events with symptoms of depression (Patient Health Questionnaire-9 scores>9), anxiety (General Anxiety Disorder-7 scores>9), and PTSD (PTSD Checklist for DSM-5 scores>30) using separate log-binomial regression models.

RESULTS

Of 426 PLWH enrolling in care, a majority were women (59%), in relationships (58%), and aged 21 to 39 years (58%). Recent death of a family member (39%) and severe illness of a family member (34%) were the most commonly reported stressful life events. In multivariable analyses, more stressful life event types, a negative relationship change, death or illness of a friend/family member, experience of violence, work-related difficulties, and feeling unsafe in one's neighborhood were independently associated with at least one of the mental health outcomes assessed. The greatest magnitude of association was observed between work-related difficulties and PTSD (adjusted prevalence ratio: 3.1; 95% confidence interval: 2.0-4.8).

LIMITATIONS

Given the design of our study, findings are subject to recall and social desirability bias.

CONCLUSIONS

Stressful life events were common among this population of PLWH entering care in Cameroon. Evidence-based interventions that improve coping, stress management, and mental health are needed.

Association between hair cortisol, hair cortisone, and fatigue in people living with HIV

Cumulative evidence to date largely supports an association between dysregulation of the activity of the hypothalamic-pituitary-adrenal (HPA) axis and fatigue. People living with HIV (PLHIV), in particular, are vulnerable to both HPA axis dysregulation and fatigue. Few investigations have examined the possible role of HPA-axis dysfunction in the occurrence of fatigue in PLHIV. This cross-sectional study aimed to investigate the association between glucocorticoids in hair, retrospective indicators of long-term HPA axis activity and biomarkers of chronic stress, and fatigue in PLHIV. A total of 446 PLHIV from Guangxi China provided hair samples for cortisol and cortisone assay and provided information on fatigue levels, sociodemographic, lifestyle, and HIV-related characteristics. Results showed that before and after controlling sociodemographic, lifestyle, and HIV-related characteristics, hair cortisone levels, but not hair cortisol levels, were associated with fatigue levels in PLHIV. In conclusion, we found that higher cortisone levels are associated with greater fatigue levels in a large cohort of Chinese PLHIV.LAY SUMMARYWe found that hair cortisone levels were significantly associated with fatigue levels in a large cohort of Chinese PLHIV. Hair cortisol levels were, however, not associated with fatigue levels in the PLHIV studied. We thus show that Chinese PLHIV who have higher cortisone levels are associated with higher fatigue levels.

A Biopsychosocial Approach to HIV Fatigue: A Cross-Sectional and Prospective Analysis to Identify Key Modifiable Factors

This study aimed to identify the prevalence and predictors of current fatigue and fatigue at 1-year follow-up, in people with HIV. Participants were recruited from HIV outpatient clinics in London, England. We explored a range of bio-psychosocial factors associated with current fatigue severity, identifying the most salient factors in a multifactorial model. A prospective study explored the predictive value of specific psychological and behavioral factors in predicting fatigue severity at one year. Sixty-four of 131 (49%) participants met the criteria for clinically significant fatigue at baseline. Psychological and behavioral variables, but not immune-virologic markers or antiretroviral treatment, were associated with current fatigue severity. In the multifactorial model, catastrophizing and distress independently predicted current fatigue severity. Higher levels of fatigue at 1 year was predicted by baseline catastrophizing, symptom focusing, distress and sleep quality, when controlling for baseline fatigue, clinical and demographic variables. These findings suggest psychological and behavioral factors are important in the maintenance of fatigue in people with HIV and identify potential opportunities for treatment. Future interventions for fatigue in HIV should not only address anxiety, depression and distress but could be optimized by targeting psychological processes such as catastrophic thinking styles and symptom focusing.

"I just keep quiet about it and act as if everything is alright" - The cascade from trauma to disengagement among adolescents living with HIV in western Kenya

INTRODUCTION

There are approximately 1.7 million adolescents living with HIV (ALHIV, ages 10 to 19) globally, including 110,000 in Kenya. While ALHIV experience poor retention in care, limited data exist on factors underlying disengagement. We investigated the burden of trauma among disengaged ALHIV in western Kenya, and its potential role in HIV care disengagement.

METHODS

We performed in-depth qualitative interviews with ALHIV who had disengaged from care at two sites, their caregivers and healthcare workers (HCW) at 10 sites, from 2018 to 2020. Disengagement was defined as not attending clinic ≥60 days past a missed scheduled visit. ALHIV and their caregivers were traced through phone calls and home visits. Interviews ascertained barriers and facilitators to adolescent retention in HIV care. Dedicated questions elicited narratives surrounding traumatic experiences, and the ways in which these did or did not impact retention in care. Through thematic analysis, a conceptual model emerged for a cascade from adolescent experience of trauma to disengagement from HIV care.

RESULTS

Interviews were conducted with 42 disengaged ALHIV, 34 caregivers and 28 HCW. ALHIV experienced a high burden of trauma from a range of stressors, including experiences at HIV disclosure or diagnosis, the loss of parents, enacted stigma and physical or sexual violence. A confluence of factors - trauma, stigma and isolation, and lack of social support - led to hopelessness and depression. These factors compounded each other, and resulted in complex mental health burdens, poor antiretroviral adherence and care disengagement. HCW approaches aligned with the factors in this model, suggesting that these areas represent targets for intervention and provision of trauma-informed care.

CONCLUSIONS

Trauma is a major factor underlying disengagement from HIV care among Kenyan adolescents. We describe a cascade of factors representing areas for intervention to support mental health and retention in HIV care. These include not only the provision of mental healthcare, but also preventing or addressing violence, trauma and stigma, and reinforcing social and familial support surrounding vulnerable adolescents. In this conceptualization, supporting retention in HIV care requires a trauma-informed approach, both in the individualized care of ALHIV and in the development of strategies and policies to support adolescent health outcomes.

Unmet needs of symptom management and associated factors among the HIV-positive population in Shanghai, China: A cross-sectional study

BACKGROUND

People living with HIV/AIDS (PLWHA) are a vulnerable group who experience multiple physiological and psychological symptoms. A better understanding of unmet symptom management needs will allow researchers to design interventions that are more reflective of deficits in care and more effective at improving patient care. Few studies have focused on unmet needs for symptom management in PLWHA particularly in China. Factors influencing Chinese PLWHA symptom management needs are rarely discussed.

AIM

The purpose of this study was to investigate the unmet needs for symptom management of PLWHA and how their symptom burden, HIV perceived stigma, and self-management capacity contributes to HIV-related self-management practices in Shanghai, China.

DESIGN

Study participants were recruited from the outpatient and inpatient HIV/AIDS wards in an infectious hospital in Shanghai, China. Self-administered questionnaires were implemented and medical charts were reviewed.

RESULTS

A total of 367 participants was recruited from April to September 2017. The results show that 53.1% (195 of 367) of participants presented at least one unmet symptom management need and that symptom burden, as well as perceived stigma, reduced self-management capacity, and no employment significantly affected unmet symptom management needs.

CONCLUSION

The findings indicate that there is room for improvement in symptom management for Chinese PLWHA. Culturally appropriate interventions focusing on improving symptom burden, decreasing HIV perceived stigma, and enhancing self-management capacity can enhance symptom management in this population.

Metabolomics of sleep disorders in HIV: a narrative review

PURPOSE

Sleep disturbances are prevalent among patients with human immunodeficiency virus (HIV), even those who are being treated on antiretroviral therapy. It is important to understand the metabolomic mechanisms underlying sleep disturbances among people living with HIV (PLWH).

METHODS

A review of recent literature was performed to explore the use of metabolomics in understanding sleep among PLWH.

RESULTS

We found only two studies that used metabolomics to explore sleep health among PLWH.

CONCLUSION

This paper reviews common sleep disorders in HIV, the existing metabolomic studies that may explain the relationship, and implications for future research. The use of metabolomics in exploring sleep disorders among PLWH will help to elucidate mechanistic links to improve patient outcomes.

A Feasibility Study to Develop and Test a Cognitive Behavioral Stress Management Mobile Health Application for HIV-Related Fatigue

CONTEXT

Exacerbated by life stressors, fatigue is the most common symptom for people living with HIV.

OBJECTIVE

To adapt, develop, and assess the feasibility of a Cognitive Behavioral Stress Management Mobile Health (CBSM mHealth) application (app) for HIV-related fatigue.

METHODS

This study had two phases: app development with key informants (N = 5) and a randomized controlled trial (N = 30). Patients randomized to the intervention group completed 10 weekly CBSM modules; those in the control group received a generic healthy lifestyle app. Measures included HIV-related fatigue, depression, anxiety, stressful life events, CD4 count, HIV viral load, credibility and acceptability of the intervention, and barriers to treatment participation.

RESULTS

We were able to recruit participants for this study, and they were able to complete the required measures. They found the intervention to be credible and acceptable and reported few barriers to treatment participation. The direction of change in the primary outcome, a decrease in fatigue, is in the expected direction and provides evidence of the promise of the intervention, which still needs to be tested in an adequately powered trial. For completers (randomized to the intervention group and completed at least 80% of the modules), there were significant changes (95% CI; lower scores indicate improvement) in fatigue intensity (from 64.2 to 59.7) and overall fatigue-related functioning (from 6.6 to 4.2).

CONCLUSION

We have proof of concept as to the feasibility, acceptability, and initial signals of efficacy for an mHealth intervention to help people with HIV-related fatigue better cope with stress and reduce their fatigue.

Blunted Expansion of Regulatory T Lymphocytes Is Associated With Increased Bacterial Translocation in Patients With Major Depressive Disorder

Background: Major Depressive Disorder (MDD) is associated with both proinflammatory and adaptive immune response abnormalities. Regulatory T lymphocytes (Tregs), a subtype of CD4+ T cells, are relevant for maintaining immune-inflammatory system homeostasis and control of inflammation such as the kind potentially induced by the interactions between the intestinal microbiome and gut mucosa. We investigated the Treg population and its distribution along their stages of differentiation/activation, as well as its function in MDD patients without concomitant diseases. We also studied the potential association between Treg alterations, intestinal barrier damage, and bacterial translocation. Methods: 30 MDD patients and 20 healthy controls were studied. The levels of circulating CD25FoxP3⁺ Tregs and their distribution on the naïve (T_N), effector (T_E), central (T_CM), and effector memory(T_EM) differentiation/activation stages were analyzed using polychromatic flow cytometry. Chemokine receptors (CCR) 2, 5, and 6, and the intracytoplasmic IL-10 expression by the Tregs were also analyzed. The serum IL-10 was measured using Luminex. The serum levels of zonulin and the intestinal fatty acid-binding protein (I-FABP), both markers of gut barrier function, and the LPS-binding protein (LBP), a marker of bacterial translocation, were measured using an enzyme-linked immunosorbent assay. Results: MDD patients had increased number of circulating Tregs cells with enhanced number of Tregs at the T_N, T_E, T_CM, and T_EM stages. The percentage of Tregs cells at T_N stage was significantly higher in MDD patients. The percentage of Tregs that expressed CCR2 and CCR6 was increased as well as those expressing IL-10. MDD patients had significantly increased levels of circulating I-FABP and LBP. MDD patients with high LBP levels had a significant reduction in the number of circulating Tregs compared to normal-LBP MDD patients. Conclusions: MDD patients showed an expansion of circulating Tregs and their CD25^highFoxP3⁺ and CD25^lowFoxP3⁺ subsets throughout the different stages of CD4+ T lymphocyte differentiation/activation. Tregs also showed an increased frequency of cells expressing CCR6 and CCR2. IL-10 Treg production was also enhanced in MDD patients that concurrently had increased serum IL-10 levels. However, this Treg expansion was blunted in MDD patients with gut barrier damage and increased bacterial translocation.

Transgender women and HIV-related health disparities: falling off the HIV treatment cascade

Background Transgender women living with HIV infection experience poorer health outcomes across the HIV continuum of care. While disparities are well established, their underlying mechanisms are not well understood. This study examined the HIV continuum of care (also known as the HIV treatment cascade), including linkage and engagement in care and health status among transgender women and cisgender women and cisgender men living with HIV.

METHOD

Case-control matching was applied to a cohort of 1101 people living with HIV; 70 transgender women living with HIV were matched on years since testing HIV positive with cisgender women and cisgender men. Participants provided measures indicative of the HIV treatment cascade that included linkage and engagement in care, receiving and adhering to antiretroviral therapy (ART), and HIV viral suppression. Common correlates of HIV-related health status: depression symptoms, HIV-related stress, alcohol and drug use, healthcare conspiracy beliefs, medical mistrust, emotional social support and tangible social support, were also assessed.

RESULTS

Transgender women were significantly less likely to receive ART, were less adherent to ART and had poorer HIV viral suppression than cisgender persons. Multivariable models demonstrated that health disparities were predicted by transgender women having poorer tangible social support over and above the other correlates of health outcomes.

CONCLUSION

Tangible support is amenable by interventions such as building and strengthening supportive networks and paraprofessional services. Socially supportive interventions should be considered critical in efforts to decrease HIV health disparities among transgender women.

Mental Health Diagnoses, Symptoms, and Service Utilization in US Youth with Perinatal HIV Infection or HIV Exposure

Youth perinatally HIV infected (PHIV) or HIV exposed, but uninfected (PHEU), are aging into adolescence and adulthood with multiple complex risk factors for mental health (MH) problems and poor MH treatment utilization. Our aims were to estimate prevalence of MH diagnoses, clinically significant symptoms, and MH treatment utilization among youth with PHIV and among PHEU youth, 10-22 years old. We also aimed to identify correlates of diagnoses and treatment utilization. Analyses of data from standardized interviews, behavioral assessments, and chart review of 551 youth revealed that 36% had a previous or current MH diagnosis, with no significant HIV status group differences. Prevalence of clinically significant symptoms was 15% for both groups, of whom a third had no diagnosis, and half were not receiving treatment. Among youth with a current MH diagnosis, those with PHIV had greater utilization of services than PHEU youth (67% vs. 51%; p = 0.04). Factors associated with MH diagnoses and/or treatment utilization included caregiver characteristics, age and sex of child, HIV status, and stressful life events. Prevalence of MH diagnoses was higher than in the general population, but lower than in similar perinatally HIV-exposed cohorts, with some unmet service needs, particularly in PHEU youth. Family characteristics warrant careful consideration in early diagnosis and treatment of MH problems among youth affected by HIV.

Psychometric properties of the Korean version of the medical outcomes study HIV health survey: results from a multicenter survey in Korea

Background

Precise assessment of health-related quality of life (HRQOL) with a reliable and valid measure is a prerequisite to the enhancement of HRQOL. This study examined the psychometric properties of the Korean version of the Medical Outcomes Study HIV Health Survey (K-MOS-HIV).

Methods

The reliability and validity of the K-MOS-HIV were examined in a multicenter survey involving 201 outpatients with human immunodeficiency virus (HIV)/ acquired immunodeficiency syndrome (AIDS) from four teaching hospitals throughout Korea.

Results

Ceiling effects were observed in six subscales scores, particularly, for the role functioning (71.1%), social functioning (63.2%), and pain (48.8%) scores. The Cronbach’s α for the physical health summary and mental health summary were 0.90 and 0.94, respectively, and it ranged from 0.78 to 0.95 for the subscales. The results of the exploratory structural equation modeling supported the two-factor structure of the K-MOS-HIV (physical health summary and mental health summary). An examination of the mean square statistics values from the Rasch analysis showed that the information-weighted fit and outlier-sensitive fit statistics were within the acceptable ranges of 0.6–1.4 except for two items in the mental health summary. The convergent validity of the K-MOS-HIV was supported by its significant positive correlations with the World Health Organization Quality of Life-HIV-BREF subscale scores. Its known-group validity was proven with its ability to detect significant differences in several K-MOS-HIV subscale scores among participants with different sociodemographic and clinical characteristics.

Conclusions

The K-MOS-HIV health survey appears to be a reliable and valid measure of HRQOL.

Major depression disorder trajectories and HIV disease progression: results from a 6-year outpatient clinic cohort

Contradictory evidence exists on the role of Major depression disorder (MDD) as a predictor of human immunodeficiency virus (HIV) disease progression, particularly regarding the effect of MDD presence versus pattern of illness. The objective of this study was to examine whether MDD status and pattern of illness differentially predict HIV disease progression. Retrospective cohort data from a six-year follow-up of HIV patients at an outpatient clinic were analyzed. MDD trajectories were identified by latent class growth analysis and generalized linear mixed models were used to examine their relation to low CD4+ T-lymphocyte counts (<200 cells/μL) during follow-up. Among 1,494 HIV patients, four MDD trajectory groups were identified: Low-Chronic, Moderate-Ascending, High-Episodic, and High-Chronic. Trajectory group membership was predicted by male sex (P = .04), minority race (P < .01), older age (P < .01) and low baseline CD4 count (P = .04). The High-Chronic group had lower odds of having a low CD4 count than the Low-Chronic group (adjusted Odds Ratio [aOR]: 0.63; 95%CI: 0.49-0.81) while the Moderate-Ascending group had higher odds (aOR: 1.53; 95%CI: 1.08-2.19). The odds of having a low CD4 count were higher among male (aOR: 1.25; 95%CI: 1.03-1.52), minority races (American Indian [aOR: 1.85; 95%CI: 1.38-2.49] and African Americans [aOR: 1.58; 95%CI: 1.33-1.87]), Hispanic (aOR: 1.52; 95%CI: 1.06-2.18), and divorced/separated patients (aOR: 1.62; 95%CI: 1.16-2.28) but decreased over time (P < .01) across trajectory groups. In this study, because MDD trajectories and CD4 counts were determined based on secondary data abstracted from electronic medical records, the results should be interpreted cautiously due to the potential for selection and misclassification bias. Overall, study findings suggest the pattern of MDD illness among HIV patients can be classified into clinically meaningful trajectory groups that appear to be programmed by known risk factors, and are useful for predicting HIV disease progression. Targeted interventions among at-risk patients may be critical to altering MDD illness patterns and curtailing HIV disease progression.

Factors Associated with Sexual Risk of HIV Transmission Among HIV-Positive Latino Men Who have Sex with Men on the U.S.-México Border

We present results from a cross-sectional, clinic-based survey of border-region Latino men who have sex with men (MSM) and who also are living with HIV in the El Paso-Ciudad Juárez area. Among the 66 participants who reported serodiscordant anal or vaginal intercourse, we examined levels of psychological distress and substance use and the association of these variables with condomless sex. Bivariate analyses indicated that MSM who reported condomless sex with a serodiscordant partner were more likely to report higher scores on measures of anxiety, depression, and trauma. These men were also more likely to report more days of alcohol use to the point of intoxication. In multivariate logistic regression, no variables were independently associated with sexual risk behavior, but symptoms of anxiety trended toward statistical significance. Our study is one of few reports aimed at understanding the HIV epidemic among Latino MSM living with HIV in the El Paso-Ciudad Juárez border region. Although we found no evidence of a relation between our measures of psychological distress and substance use and sexual risk behavior in multivariate analyses, psychological distress and problematic alcohol use were common in the sample and are important targets for intervention in their own right.

Alcohol Use and Human Immunodeficiency Virus (HIV) Infection: Current Knowledge, Implications, and Future Directions

Alcohol use is common among people living with human immunodeficiency virus (HIV). In this narrative review, we describe literature regarding alcohol's impact on transmission, care, coinfections, and comorbidities that are common among people living with HIV (PLWH), as well as literature regarding interventions to address alcohol use and its influences among PLWH. This narrative review identifies alcohol use as a risk factor for HIV transmission, as well as a factor impacting the clinical manifestations and management of HIV. Alcohol use appears to have additive and potentially synergistic effects on common HIV-related comorbidities. We find that interventions to modify drinking and improve HIV-related risks and outcomes have had limited success to date, and we recommend research in several areas. Consistent with Office of AIDS Research/National Institutes of Health priorities, we suggest research to better understand how and at what levels alcohol influences comorbid conditions among PLWH, to elucidate the mechanisms by which alcohol use is impacting comorbidities, and to understand whether decreases in alcohol use improve HIV-relevant outcomes. This should include studies regarding whether state-of-the-art medications used to treat common coinfections are safe for PLWH who drink alcohol. We recommend that future research among PLWH include validated self-report measures of alcohol use and/or biological measurements, ideally both. Additionally, subgroup variation in associations should be identified to ensure that the risks of particularly vulnerable populations are understood. This body of research should serve as a foundation for a next generation of intervention studies to address alcohol use from transmission to treatment of HIV. Intervention studies should inform implementation efforts to improve provision of alcohol-related interventions and treatments for PLWH in healthcare settings. By making further progress on understanding how alcohol use affects PLWH in the era of HIV as a chronic condition, this research should inform how we can mitigate transmission, achieve viral suppression, and avoid exacerbating common comorbidities of HIV and alcohol use and make progress toward the 90-90-90 goals for engagement in the HIV treatment cascade.

Childhood sexual abuse and depression in Latino men who have sex with men: Does resilience protect against nonadherence to antiretroviral therapy?

This study tested depression as a mediator between childhood sexual abuse and adherence to antiretroviral therapy, an effect moderated by resilience. In total, 149 HIV+ Latino men who have sex with men were recruited for this study. Using a regression-based bootstrap approach, depression mediated the relationship between childhood sexual abuse and antiretroviral therapy adherence, with worse adherence for participants at lowest percentiles of the resilience index. The prevalence of childhood sexual abuse and depression in HIV+ men who have sex with men is high and must be addressed to better prevent disease progression and reduce transmission, especially in expanding Latino populations.

A horse in zebra stripes: a peculiar case of undetected end-stage AIDS

OBJECTIVE

Late HIV diagnosis occurs in up to 45% of new HIV cases in the developed world and is linked to worse health outcomes, including more hospitalizations, higher health care resource utilization and less robust responses to highly active antiretroviral therapy.

METHOD

Case report

RESULTS

A 70-year-old woman with an obscure constellation of medical and psychiatric complaints ultimately proved to have end-stage acquired immunodeficiency syndrome discovered much too late. Curiously, she had no obvious risk factors for HIV infection.

CONCLUSION

This tragic case underscores the importance of keeping HIV infection in the differential for a patient with diverse vague complaints. Let this story caution its readers: when you hear hoof beats, do not look for zebras - even when you are least expecting a horse.

Fatigue in HIV-Infected People: A Three-Year Observational Study

CONTEXT

HIV-related fatigue remains the most frequent complaint of seropositive patients.

OBJECTIVES

To describe the natural course of fatigue in HIV infection, in a sample (n=128) followed for a three-year period.

METHODS

A longitudinal prospective design was used to determine what factors influenced changes in fatigue intensity and fatigue-related impairment of functioning in a community-dwelling sample of HIV-infected individuals. Participants were followed every six months for a three-year period. At each study visit, we collected data on a large number of physiological and psychosocial markers that have been shown to be related to fatigue in HIV-infected people. At three month intervals between study visits, we collected data on fatigue via mailed questionnaires.

RESULTS

Fatigue in HIV infection is largely a result of stressful life events, and is closely tied to the anxiety and depression that accompany such events. Fatigue did not remit spontaneously over the course of the study, indicating the need for interventions to ameliorate this debilitating symptom.

CONCLUSION

Intervening to help people who are suffering from HIV-related fatigue to deal with stressful life events may help to ameliorate this debilitating symptom.

The role of neuroplasticity and cognitive reserve in aging with HIV: recommendations for cognitive protection and rehabilitation

By and large, the immune systems of people infected with HIV are being protected and maintained by advances in highly active antiretroviral therapy; as such, this is extending the lives of people into old age. Unfortunately, for many living with this disease, HIV is associated with neuroinflammation, co-morbidities, and accelerated aging which can compromise brain function, resulting in cognitive deficits. The purpose of this article is to highlight how to interpret these deficits within the framework of neuroplasticity and cognitive reserve for this clinical population. We suggest several recommendations for cognitive rehabilitation and mitigation such as addressing lifestyle factors, psychostimulants, cognitive remediation therapy, and treatment of depression and anxiety. Implications for nursing research and practice are posited.

Substantial symptom changes in naturalistic recovery from aversive events

OBJECTIVE

Researchers have recommended examining trajectories of recovery from aversive events, including sudden gains and spikes. We examined rates, attributions for, and outcomes associated with substantial symptom improvements and brief exacerbations after aversive events.

METHOD

Sixty-three women completed questionnaire measures of mood, depression, and posttraumatic stress disorder symptoms. They used a Life History Calendar (LHC) to draw the trajectory of symptom levels from the event to the present, and were interviewed regarding the course of their symptoms. Based on the LHC and interview, we coded whether each participant experienced substantial improvements and/or brief exacerbations and reasons for them.

RESULTS

Participants frequently experienced substantial improvements and brief exacerbations, most of which they attributed to external events. Substantial improvements-but not substantial brief exacerbations-were associated with significantly lower symptom levels.

CONCLUSION

Substantial improvements are similar to sudden gains in therapy samples. Substantial improvements in avoidance and mood have positive, bidirectional effects on each other.

Cognitive Consequences of Aging with HIV: Implications for Neuroplasticity and Rehabilitation

Combination active antiretroviral therapy prevents HIV from replicating and ravaging the immune system, thus allowing people to age with this disease. Unfortunately, the synergistic effects of HIV and aging can predispose many to become more at-risk of developing cognitive deficits which can interfere with medical management, everyday functioning, and quality of life. The purpose of this article is to describe the role of cognitive reserve and neuroplasticity on cognitive functioning in those aging with this disease. Specifically, the role of environment and the health of these individuals can compromise cognitive functioning. Fortunately, some cognitive interventions such as prevention and management of co-morbidities, cognitive remediation therapy, and neurotropic medications may be of value in preventing and rehabilitating the cognitive consequences of aging with HIV. Novel approaches such as cognitive prescriptions, transcranial direct stimulation, and binaural beat therapy may also be considered as possible techniques for cognitive rehabilitation.

Factors associated with fatigue in acquired immunodeficiency syndrome patients with antiretroviral drug adverse reactions: a retrospective study

OBJECTIVE

To retrospectively study the prevalence of fatigue and factors associated with fatigue among acquired immunodeficiency syndrome (AIDS) patients with antiretroviral drug adverse reactions.

METHODS

Data were collected from case report forms (CRFs) for a project funded by the 11th National 5-year Special Science and Technology Program on Major Infectious Diseases. Fatigue was defined by patient self-report. The outcomes were the prevalence of fatigue and the potential risk factors of fatigue. Univariate and multivariate logistic regression analyses were conducted to identify the factors associated with fatigue.

RESULTS

Among the 228 subjects, the prevalence of fatigue was 86.8%. In univariate analysis, the significant differences in demographic characteristics between patients with and without fatigue were: gender [OR = 2.29; 95% CI (1.05-4.98)], education level [OR = 0.40; 95% CI (0.18-0.85)], anemia [OR = 3.80; 95% CI (1.27-11.31)], time of HIV diagnosis [OR = 0.29; 95% CI (0.13-0.65)], and route of infection [OR = 0.14; 95% CI (0.06-0.32)]. Abnormal taste and rapid pulse were more commonly seen in patients with fatigue (P < 0.05), while abdominal distension and lumbar soreness were encountered less often in patients with fatigue (P < 0.05). Multivariate analysis showed that the four main factors associated with fatigue were anemia [OR = 3.50; 95% CI (1.01-12.15)], route of infection [OR = 3.40; 95% CI (1.21-9.58); P = 0.02 < 0.05], lumbar soreness [OR = 0.06; 95% CI (0.02-0.18); P = 0.000 < 0.05], and rapid pulse [OR = 10.58; 95% CI (2.16-51.75); P = 0.004 < 0.05].

CONCLUSION

This study demonstrated that fatigue is common (86.8% prevalence) in AIDS patients with antiretroviral drug adverse reactions, and that anemia, route of infection (i.e., non-commercial blood donation) and rapid pulse were risk factors, while lumbar soreness was a protective factor related to fatigue. More attention should be paid to fatigue and more efforts should be made to find ways to prevent, control and eliminate this symptom in AIDS patients with antiretroviral drug adverse reactions.

Intensity, chronicity, circumstances, and consequences of HIV-related fatigue: a longitudinal study

HIV-related fatigue remains the most troubling complaint of seropositive people. Researchers often use tools to measure fatigue that were developed for other patient populations; thus, the measurement of fatigue specific to HIV is needed. This article describes results from the HIV-Related Fatigue Scale (HRFS) including: (a) the variability in intensity and chronicity of HIV-related fatigue, (b) the circumstances surrounding changes in fatigue, (c) the impact of fatigue on activities of daily living (ADLs), and (d) the consequences of HIV-related fatigue. We collected data every 3 months over a 3-year period from 128 people. HIV-related fatigue was chronic and did not appear to remit spontaneously; those who were the most fatigued at the beginning of the study remained the most fatigued over 3 years. Fatigue interfered more with instrumental activities of daily living than basic ADLs; it also interfered with work, family, and social life. Stress and depression increased fatigue.

Fatigue and Sleep Disturbance Related to Perceived Stress in Chinese HIV-Positive Individuals: A Mixed Methods Study

BACKGROUND

Few studies of HIV+ individuals in China have examined the associations between HIV-related stress with sleep disturbance and fatigue, which are common complaints among people living with HIV/AIDS (PLWHA). We carried out this study to examine the relationships among perceived stress, sleep disturbance, and fatigue in PLWHA in China.

METHODS

A mixed methods study design was used during data collection in Shanghai, China, from December 2009 to March 2010. Qualitative in-depth interviews were conducted with 19 HIV+ females. Additionally, cross-sectional audio computer-assisted self-interviews (ACASI) were conducted to collect quantitative data from a convenience sample of 107 HIV+ patients (84% were male) including the following scales: 1) Perceived Stress Scale for PLWHA, 2) General Sleep Disturbance Scale, and 3) Fatigue Scale.

RESULTS

The major themes that emerged from the in-depth interviews were around life stress with HIV, sleep disturbance, and fatigue. Participants presented varying amounts of stress around worrying about whether to disclose their diagnosis and whether they might transmit the disease to their family. In addition, in the cross-sectional data, 40% of the participants reported clinically significant sleep disturbances (GSDS > 3) with an average of 3 nights of disturbed sleep in the past week (M=2.87, SD=1.21) and moderate fatigue severity (M=5.24, SD=2.27). In mediation analyses, the data suggests that the relationship between perceived stress and fatigue was largely (53%) mediated through sleep disturbance.

CONCLUSIONS

Chinese PLWHA described how stress had caused them to become sleepless and fatigued. The quantitative data also demonstrated significant levels of sleep disturbance and fatigue, where were due to perceived stress with HIV disease. A systematic self-management intervention to decrease perceived stress should be designed and implemented in mental health resource-limited settings such as China in order to reduce sleep disturbance and fatigue.

Assessing and treating forgetfulness and cognitive problems in adults with HIV

In addition to the immune system, HIV affects the nervous system and the brain, producing neurological sequelae, often resulting in forgetfulness and cognitive problems. These problems can compromise medication adherence, interfere with instrumental activities of daily living such as driving and managing finances, increase dependency, and decrease quality of life. Cognitive problems emerge due to a variety of reasons; likewise, several evidence-based methods to mitigate causes and compensate for cognitive problems can be used alone or in combination. This article focuses on nonpathological, nondementia forgetfulness and cognitive problems. However, dementia must be considered and assessed as measured by marked cognitive decline over time. Methods for assessing and measuring forgetfulness and cognitive problems are provided. In addition, methods of treating nonpathological cognitive problems are provided, ranging from Recommended for Practice to Not Recommended for Practice. A case study is presented to demonstrate how to implement recommended treatment options.

Predictors of late presentation for HIV diagnosis: a literature review and suggested way forward

Early commencement of antiretroviral treatment can be beneficial and economical in the long run. Despite global advances in access to care, a significant proportion of adults presenting at HIV/AIDS care facilities present with advanced HIV disease. Understanding factors associated with late presentation for HIV/AIDS services is critical to the development of effective programs and treatment strategies. Literature on factors associated with late presentation for an HIV diagnosis is reviewed. Highlighted is the current emphasis on socio-demographic factors, the limited exploration of psychosocial correlates, and inconsistencies in the definition of late presentation that make it difficult to compare findings across different studies. Perspectives based on experiences from resource limited settings are underreported. Greater exploration of psychosocial predictors of late HIV diagnosis is advocated for, to guide future intervention research and to inform public policy and practice targeted at 'difficult to reach' populations.

Fatigue and sleep disturbance in HIV-positive women: a qualitative and biomedical approach

AIMS AND OBJECTIVES

This study explores how sleep and energy levels were affected in Chinese women diagnosed with HIV in China employing the Actiwatch actigraphy system to collect data on the women's sleep characteristics.

BACKGROUND

The worldwide AIDS pandemic, a major impetus behind the recent focus on global aspects of health, is one area in which the behavioural and biomedical expertise of nursing science is sorely needed. In particular, few studies of HIV+ women have examined the association of HIV-related stress with sleep disturbance and fatigue. Especially, fatigue and sleep disturbances are a common complaint among people with HIV.

DESIGN

A qualitative study with actigraphy device used.

METHODS

In-depth interviews were conducted with 19 HIV+ women in Shanghai, China, from December 2009-March 2010 and within this group, nine of the women agreed to wear an Actiwatch actigraphy device for 72 hours.

RESULTS

Two major themes emerged from the in-depth interviews are as follows: sleep disturbance and fatigue. Participants presented varying amounts of sleeplessness, and fatigue resulting from nightmares, worrying about whether to disclose their diagnosis, and whether they might transmit the disease to their partners or children. Among the nine Actiwatch study participants, data shown that those who experienced fragmented sleep also slept more during the daytime.

CONCLUSIONS

In this study, Chinese HIV+ women described how stress had caused them to become sleepless. The objective data collected via Actiwatch showed that these women required longer nap times, which indicates they did not have refreshing nocturnal sleep. Designing a culturally acceptable stress management intervention for these women is urgently needed.

RELEVANCE TO CLINICAL PRACTICE

Sleep and fatigue level should be evaluated in each visit with HIV care. Nurses need to be trained in evaluating the HIV+ patients' sleep and fatigue status and refer them to psychologist and/or relaxation technique accordingly. Self-management intervention for HIV+ individuals should also include the sleep hygiene into consideration.

The relationship between positive psychological attributes and psychological well-being in persons with HIV/AIDS

The relationship between personal psychological attributes and psychological well-being was assessed among adults with HIV/AIDS. The predictive power of sense of coherence, dispositional optimism and perceived competence (PC) on positive affect (PA), negative affect (NA) and relative mood (PA-NA) were assessed using hierarchical linear regression analysis of two data collections, 2 months apart, from 124 HIV-infected participants. In cross-sectional models all of the baseline psychological attributes accounted for a significant amount of variance in the well-being measures. In longitudinal analyses, changes in PA were predicted by PC and dispositional optimism but not by sense of coherence. The positive psychological attributes did not predict changes in NA. Sense of coherence, dispositional optimism and PC, individually and in composite form, significantly correlate with psychological well-being among HIV infected persons. However, change in psychological well-being might be best predicted by PC.

Association between stigma, depression and quality of life of people living with HIV/AIDS (PLHA) in South India - a community based cross sectional study

Background

India has around 2.27 million adults living with HIV/AIDS who face several challenges in the medical management of their disease. Stigma, discrimination and psychosocial issues are prevalent. The objective of the study was to determine the prevalence of severe stigma and to study the association between this, depression and the quality of life (QOL) of people living with HIV/AIDS (PLHA) in Tamil Nadu.

Methods

This was a community based cross sectional study carried out in seven districts of Tamil Nadu, India, among 400 PLHA in the year 2009. The following scales were used for stigma, depression and quality of life, Berger scale, Major Depression Inventory (MDI) scale and the WHO BREF scale. Both Stigma and QOL were classified as none, moderate or severe/poor based on the tertile cut off values of the scale scores. Depression was classified as none, mild, moderate and severe. Logistic regression analyses were performed to study the risk factors.

Results

Twenty seven per cent of PLHA had experienced severe forms of stigma. These were severe forms of personalized stigma (28.8%), negative self-image (30.3%), perceived public attitude (18.2%) and disclosure concerns (26%). PLHA experiencing severe depression were 12% and those experiencing poor quality of life were 34%. Poor QOL reported in the physical, psychological, social and environmental domains was 42.5%, 40%, 51.2% and 34% respectively. PLHA who had severe personalized stigma and negative self-image had 3.4 (1.6-7.0) and 2.1 (1.0-4.1) times higher risk of severe depression respectively (p < .001). PLHA who had severe depression had experienced 2.7(1.1-7.7) times significantly poorer QOL.

Conclusions

Severe forms of stigma were equivalently prevalent among all the categories of PLHA. However, PLHA who had experienced severe depression had only developed poor QOL. A high level of social support was associated with a high level of QOL.

Predicting fatigue in patients using home parenteral nutrition: a longitudinal study

Background

Home parenteral nutrition (HPN) is a life-saving therapy for patients with diseases that preclude adequate oral or enteral food intake. HPN has a large impact on daily life. Many patients suffer from fatigue and depression, and they experience limits in social activities. This all contributes to a lower quality of life.

Purpose

Fatigue is the most frequently mentioned problem in Dutch HPN patients. Therefore, we studied the prevalence, course and predictors of fatigue in these patients.

Methods

Patients completed questionnaires at baseline and follow-up (12 months later). Measurements included fatigue, depression, functional impairment, social support, self-efficacy, coping, anxiety and acceptance. Laboratory measures, including total bilirubin, creatinine, albumin and haemoglobin levels, were obtained from the medical records. Descriptive statistics, correlations and linear regression analysis were performed.

Results

The response rate was 71% (n = 75). Sixty-five per cent of the patients were severely fatigued (n = 49). Eighty-nine per cent experienced persistent fatigue. Baseline fatigue predicted 57% of the variance of fatigue at follow-up, and avoidance was responsible for 3% of the variance. No significant correlations between fatigue and laboratory measures were found. A cross-sectional analysis showed that 46% of the variance of fatigue was explained by functional impairment, self-efficacy and depression.

Conclusion

Severe fatigue is a persistent problem for HPN patients. Baseline fatigue was the strongest predictor of fatigue at follow-up. Functional impairment, self-efficacy and depression are strongly related to fatigue. Early recognition and treatment of fatigue are important.

Patterns of morning and evening fatigue among adults with HIV/AIDS

AIMS AND OBJECTIVES

Describe patterns of morning and evening fatigue in adults with HIV and examine their relationship to demographic and clinical factors and other symptoms.

BACKGROUND

Most studies of HIV-related fatigue assess average levels of fatigue and do not address its diurnal fluctuations. Patterns of fatigue over the course of the day may have important implications for assessment and treatment.

DESIGN

A cross-sectional, correlational design was used with six repeated measures over 72 hours.

METHOD

A convenience sample of 318 HIV-infected adults was recruited in San Francisco. Socio-demographic, clinical and symptom data were collected with questionnaires. CD4+ T-cell count and viral load were obtained from medical records. Participants completed a four-item version of the Lee Fatigue Scale each morning and evening for three consecutive days. Participants were grouped based on their diurnal pattern of fatigue (high evening only, high morning only, high morning and evening and low morning and evening). Group comparisons and logistic regression were used to determine the unique predictors of each fatigue pattern.

RESULTS

The high evening fatigue pattern was associated with anxiety and the high morning pattern was associated with anxiety and depression. The morning fatigue pattern showed very little fluctuation between morning and evening, the evening pattern showed the largest fluctuation. The high morning and evening pattern was associated with anxiety, depression and sleep disturbance and this group reported the most fatigue-related distress and interference in functioning.

CONCLUSIONS

These results provide initial evidence for the importance of assessing the patient's daily pattern of fatigue fluctuation, as different patterns were associated with different symptom experiences and perhaps different aetiologies.

RELEVANCE TO CLINICAL PRACTICE

Different fatigue patterns may benefit from tailored intervention strategies. Management of depressive symptoms could be tested in patients who experience high levels of morning fatigue.

Modafinil and armodafinil treatment for fatigue for HIV-positive patients with and without chronic hepatitis C

Fatigue is prevalent among patients with hepatitis C virus (HCV) and with HIV/AIDS but there are no established fatigue treatments for either condition or their combination. We analysed data from three trials of modafinil or armodafinil for HIV-positive patients with fatigue, including 36 co-infected with HCV, to compare treatment response and safety parameters related to HCV status. One hundred and twenty patients received active drug and 70 were randomized to placebo. Fatigue response rate to modafinil/armodafinil was 100% for patients with HCV (18/18) and 73% (74/102) for patients without HCV. Placebo response rate was 28% (5/18) and 29% (15/52), respectively. Depressive symptoms improved only when energy improved. Viral load declined from baseline after 12 and 26 weeks of active medication. CD4 cell count did not change, nor did alanine transaminase and aspartate aminotransferase for patients with HCV. Patients with haematocrit below the reference range responded, as well as patients whose values were within the reference range. Modafinil and armodafinil appear effective and well tolerated for treating fatigue among both HCV-positive and HCV-negative patients with HIV/AIDS, suggesting that they may hold promise for HIV-positive patients considering alpha interferon/ribavirin treatment for HCV. Further investigation in a focused trial is warranted.

Physiological and psychosocial factors that predict HIV-related fatigue

Fatigue is one of the most common and debilitating symptoms experienced by HIV-infected people. We report the results of our longitudinal analysis of physiological and psychosocial factors that were thought to predict changes in HIV-related fatigue in 128 participants over a 1-year period, in an effort to sort out the complex interplay among a comprehensive set of physiological and psychosocial variables. Physiological measures included hepatic function (aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transpeptidase, alkaline phosphatase, total bilirubin, hepatitis C status), thyroid function (thyroid stimulating hormone, thyroxine), HIV viral load, immunologic function (CD4, CD8, CD4/CD8 ratio, CD16, CD8CD38), gonadal function (testosterone, dehydroepiandrosterone), hematologic function (hemoglobin, hematocrit, serum erythropoietin), and cellular injury (lactic acid). Psychosocial measures included childhood and adult trauma, anxiety, depression, social support, stressful life events, and post-traumatic stress disorder (PTSD). Unemployment, not being on antiretroviral therapy, having fewer years since HIV diagnosis, more childhood trauma, more stressful life events, less social support, and more psychological distress (e.g., PTSD, anxiety and depression) put HIV-infected persons at risk for greater fatigue intensity and fatigue-related impairment in functioning during 1-year follow-up. Physiological variables did not predict greater fatigue. Stressful life events had both direct and indirect effects on fatigue.

Predictors and treatment strategies of HIV-related fatigue in the combined antiretroviral therapy era

OBJECTIVE

To assess predictors and reported treatment strategies of HIV-related fatigue in the combined antiretroviral (cART) era.

METHOD

Five databases were searched and reference lists of pertinent articles were checked. Studies published since 1996 on predictors or therapy of HIV-related fatigue measured by a validated instrument were selected.

RESULTS

A total of 42 studies met the inclusion criteria. The reported HIV-related fatigue prevalence in the selected studies varied from 33 to 88%. The strongest predictors for sociodemographic variables were unemployment and inadequate income. Concerning HIV-associated factors, the use of cART was the strongest predictor. Comorbidity and sleeping difficulties were important factors when assessing physiological influences. Laboratory parameters were not predictive of fatigue. The strongest and most uniform associations were observed between fatigue and psychological factors such as depression and anxiety. Reported therapeutic interventions for HIV-related fatigue include testosterone, psycho-stimulants (dextroamphetamine, methylphenidate hydrochloride, pemoline, modafinil), dehydroepiandrosterone, fluoxetine and cognitive behavioural or relaxation therapy.

CONCLUSION

HIV-related fatigue has a high prevalence and is strongly associated with psychological factors such as depression and anxiety. A validated instrument should be used to measure intensity and consequences of fatigue in HIV-infected individuals. In the case of fatigue, clinicians should not only search for physical mechanisms, but should question depression and anxiety in detail. There is a need for intervention studies comparing the effect of medication (antidepressants, anxiolytics) and behavioural interventions (cognitive-behavioural therapy, relaxation therapy, graded exercise therapy) to direct the best treatment strategy. Treatment of HIV-related fatigue is important in the care for HIV-infected patients and requires a multidisciplinary approach.

Modafinil treatment for fatigue in HIV/AIDS: a randomized placebo-controlled study

OBJECTIVE

To evaluate the efficacy and safety of modafinil in the treatment of fatigue in patients with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and to assess effect on depressive symptoms.

METHOD

Patients who were HIV+ and had clinically significant fatigue (according to the Fatigue Severity Scale [FSS]) were included in a 4-week randomized, placebo-controlled, double-blind trial. This was followed by an additional 8 weeks of open-label treatment for modafinil responders and 12 weeks for placebo nonresponders. The primary outcome measure for fatigue and depression was the Clinical Global Impressions-Improvement scale, supplemented by the FSS, Hamilton Depression Rating Scale, and Beck Depression Inventory. Safety was assessed with assays of CD4 cell count and HIV ribonucleic acid (RNA) viral load. Visits were weekly for 4 weeks, then biweekly, with a follow-up visit at 6 months. Maximum trial dose of modafinil was 200 mg/d. Data for this study were collected between December 2004 and December 2008.

RESULTS

115 patients were randomly assigned. In intention-to-treat analyses, fatigue response rate to modafinil was 73% and to placebo, 28%. Attrition was 9%. Modafinil did not have an effect on mood alone in the absence of improved energy. At week 4, CD4 cell counts did not change significantly; HIV RNA viral load showed a trend decline for patients taking modafinil but not for those taking placebo. At 6 months, those still taking modafinil had more energy and fewer depressive symptoms than patients who were not taking modafinil, and only those still taking modafinil showed a significant decline from baseline in their HIV RNA viral load.

CONCLUSIONS

Modafinil appears to be effective and well tolerated in treating fatigue in HIV+ patients. Consideration of its use is warranted considering the high prevalence of fatigue in the HIV community, its minimal side effects, and overall patient acceptance.

Symptom experience in HIV-infected adults: a function of demographic and clinical characteristics

Personal characteristics that interact with both HIV diagnosis and its medical management can influence symptom experience. Little is known about how symptoms in populations with chronic illness vary by age, sex, or socioeconomic factors. As part of an ongoing prospective longitudinal study, this report describes symptoms experienced by 317 men and women living with HIV/AIDS. Participants were recruited at HIV clinics and community sites in the San Francisco Bay Area. Measures included the most recent CD4 cell count and viral load from the medical record, demographic and treatment variables, and the 32-item Memorial Symptom Assessment Scale to estimate prevalence, severity, and distress of each symptom and global symptom burden. The median number of symptoms was nine, and symptoms experienced by more than half the sample population included lack of energy (65%), drowsiness (57%), difficulty sleeping (56%), and pain (55%). Global symptom burden was unrelated to age or CD4 cell count. Those with an AIDS diagnosis had significantly higher symptom burden scores, as did those currently receiving antiretroviral therapy. African Americans reported fewer symptoms than Caucasians or Mixed/Other race, and women reported more symptom burden after controlling for AIDS diagnosis and race. Because high symptom burden is more likely to precipitate self-care strategies that may potentially be ineffective, strategies for symptom management would be better guided by tailored interventions from health care providers.

Modafinil effects on cognitive function in HIV+ patients treated for fatigue: a placebo controlled study

Both mild cognitive impairment and fatigue are common among people with HIV/AIDS. This study examined the efficacy of modafinil for HIV+ patients who sought treatment for fatigue in a placebo-controlled double-blind 4-week trial. A battery of standard neuropsychological tests was administered at study entry and Week 4, and change in performance was compared for 59 patients receiving modafinil versus 44 patients receiving placebo. A significant effect on fatigue was observed. In addition, cognitive performance, as measured by a global change score, improved more in the modafinil than in the placebo group although the effect was not specific to any cognitive domain.

Chronicity and remission of fatigue in patients with established HIV infection

Fatigue is one of the most common and debilitating complaints of HIV-positive individuals, potentially leading to important functional limitations. We recruited 128 HIV-positive individuals (fatigued and nonfatigued) between March 2005 and May 2006; 66% were male, 66% were African American, 45% had greater than a high school education, 67% were unemployed, and ages ranged from 26-66 (median, 44). Every 3 months for 15 months, participants completed a 56-item self-report fatigue scale developed and validated by the authors. Participants were classified as fatigued or not fatigued at each assessment and received scores for fatigue intensity and impact of fatigue on functioning. We used linear mixed-effects models to assess longitudinal variation in fatigue scores and generalized estimating equations for binary outcomes to model predictors of fatigue remission among those fatigued at baseline. At baseline, 88% of the sample was fatigued. Fatigue measures were highly correlated across time points (rho 0.63-0.85 [intensity], 0.63-0.80 [functioning]) and showed no evidence of overall improvement, deterioration, or convergence over time. Predictors of lower fatigue scores included higher income, employment, longer time since HIV diagnosis, and antiretroviral therapy use. Those employed at baseline were likely to show improvements in fatigue while those unemployed were not. Of those fatigued at baseline, 11% experienced remission during follow-up; remission was associated with Caucasian race and employment. In summary, fatigue intensity and related functional limitations were persistent, stable, and unlikely to remit over 15 months of follow-up in this sample of patients with established HIV infection.

Daytime sleepiness, nighttime sleep quality, stressful life events, and HIV-related fatigue

In this report, the authors describe the relationships between daytime sleepiness, nighttime sleep quality, stressful life events, and HIV-related fatigue in a sample of 128 individuals; they report the baseline results of a longitudinal observational study. They examined sleep using the Pittsburgh Sleep Quality Index (a measure of the quality of nighttime sleep), and the Epworth Sleepiness Scale, (a measure of daytime sleepiness). Recent stressful life events were measured via a methodology developed in a previous 9-year HIV study. Poor nighttime sleep was significantly correlated with fatigue intensity (r = .46, p < .05), as was daytime sleepiness (r = .20, p < .05). However, in multiple regression models, the association between stress and fatigue intensity was not explained by daytime sleepiness and was only partially explained by nighttime sleep quality. Further research is needed to better elucidate these relationships.
