Associations Between Widespread Pain and Sleep Quality in People With HIV

Examining biopsychosocial predictors of risk for cognitive impairment among a racially diverse sample of men who have sex with men living with HIV

Background

Cognitive decline among people living with HIV (PLWH) is growing concern as world populations become increasing older including higher proportions of PLWH. It is vitally important to understand psychosocial predictors of age-related cognitive decline men who have sex with men (MSM) living with HIV.

Objectives

The current study seeks to examine psychosocial risk factors the contribute to the risk of age-related cognitive impairment as measured by Cardiovascular Risk Factors, Aging, and Incidence of Dementia (CAIDE) score in a racially diverse sample of MSM living with HIV.

Design

The present analysis utilizes data from the baseline (n = 196) and 6-month follow-up (n = 135) time points of a longitudinal cohort study of PLWH.

Methods

Using a self-report survey, we examine the associations between psychosocial predictors (e.g. trauma, mental health, chronic pain, sleep disturbance, etc.) and risk of dementia using the CAIDE risk score. Analyses include linear and logistic regression.

Results

In adjusted model stress, chronic pain, Black racial identity, and having a sexual identity that is bisexual or another category are all positively associated with CAIDE scores. Childhood sexual abuse history was negatively associated with CAIDE scores indicating a protective effect. Sleep disorder has a positive association with CAIDE scores after adjusting for the baseline CAIDE scores.

Conclusion

These results indicate modifiable correlates of cognitive risk (stress and chronic pain). Interventions should seek to address these comorbid factors including the consideration of minority stress and stigma. Interventions should seek to reach Black and bisexual men living with HIV, including possible cultural tailoring to interventions and messaging. Lastly, future research should examine the impact of variation within childhood sexual abuse histories to better understand their association with cognitive impairment later in life. This may include considering the nature, severity, and potential treatment of trauma symptoms.

Sleep deficiency among people living with human immunodeficiency virus: A growing challenge

PURPOSE OF REVIEW

The purpose of this narrative review is to consolidate and summarize the existing literature on sleep deficiency among people living with human immunodeficiency virus (HIV; PLWH), to discuss the potential impact of antiretroviral therapy on sleep deficiency and to identify priorities for future research in this area.

RECENT FINDINGS

Three important domains of sleep deficiency include alterations in sleep quality (including sleep disorders), duration and timing. The existing HIV and sleep deficiency literature, which is robust for sleep quality but sparser for sleep duration or sleep timing, has identified epidemiological correlates and outcomes associated with sleep deficiency including sociodemographic factors, HIV-specific factors, aspects of physical and mental health and cognition.

SUMMARY

Sleep deficiency is a common problem among PLWH and is likely underdiagnosed, although more high-quality research is needed in this area. Sleep quality has received the most attention in the literature via methodologies that assess subjective/self-reported sleep quality, objective sleep quality or both. There is significantly less research on sleep duration and minimal research on sleep timing. Use of certain antiretroviral therapy drugs may be associated with sleep deficiency for some individuals. Future research should utilize larger, longitudinal studies with consistent, comprehensive and validated methods to assess both subjective and objective measures of sleep deficiency to better understand the prevalence, correlates and clinical implications of sleep deficiency in PLWH.

Defining multimorbidity in people with HIV - what matters most?

PURPOSE OF REVIEW

Although multimorbidity (defined as the coexistence of multiple conditions) presents significant health challenges to people with HIV, there is currently no consensus on how it should be defined among this population. This review aimed to examine the definition of multimorbidity in existing studies among people with HIV ( n  = 22).

RECENT FINDINGS

Variation in the definition of multimorbidity (in terms of the number and nature of conditions included) across studies among people with HIV was observed, with less than half (45%) reporting a selection criteria for conditions. The number of conditions considered ranged from 4 to 65. Certain conditions (e.g. stroke, myocardial infarction and chronic kidney disease) and risk factors (e.g. hypertension) were more frequently included, while other symptoms (e.g. joint pain, peripheral neuropathy and sleeping problems) and mental health conditions (e.g. anxiety and panic attacks) were rarely included in the definition of multimorbidity.

SUMMARY

The definition of multimorbidity among people with HIV is highly variable, with certain conditions overlooked. We propose recommendations that researchers should consider when defining multimorbidity among this population to not only enable comparisons between studies/settings but also to ensure studies consider a person-centred approach that can accurately capture multimorbidity among people with HIV.

Do sleep disturbances contribute to comorbidities in HIV?

PURPOSE OF REVIEW

To highlight recent publications about sleep disorders and sleep health in adult persons with HIV (PWH), with a focus on how sleep relates to comorbidities in PWH.

RECENT FINDINGS

Sleep disorders are more common in PWH than in seronegative controls, especially insomnia, with four different recent studies estimating insomnia prevalence in PWH at 21-35%. Sleep apnea prevalence estimates in PWH have varied widely. Most studies suggest PWH do not have higher sleep apnea prevalence compared with controls, though definitions of sleep apnea may affect these analyses. Comorbidities recently associated with sleep in PWH include myocardial infraction (insomnia), depressive symptoms (insomnia and restless legs syndrome), and pain (insomnia). Cognition associations with sleep were inconsistent and may depend on data collection and analytic methods. Sleep health dimensions are uncommonly reported, but PWH appear to report worse sleep health dimensions and these demonstrated mixed associations with cognition and depressive symptoms in recent studies.

SUMMARY

Sleep disorders and poor sleep health are common in PWH and are related to comorbidities. More data from longitudinal studies and clinical trials are needed. Clinical trials of insomnia interventions in PWH are especially warranted.

Myelin regulatory factor is a target of individual and interactive effects of HIV-1 Tat and morphine in the striatum and pre-frontal cortex

HIV-associated neurocognitive disorders (HAND) remain pervasive even with increased efficacy/use of antiretroviral therapies. Opioid use/abuse among HIV + individuals is documented to exacerbate CNS deficits. White matter (WM) alterations, including myelin pallor, and volume/structural alterations detected by diffusion tensor imaging are common observations in HIV + individuals, and studies in non-human primates suggest that WM may harbor virus. Using transgenic mice that express the HIV-1 Tat protein, we examined in vivo effects of 2-6 weeks of Tat and morphine exposure on WM using genomic and biochemical methods. RNA sequencing of striatal tissue at 2 weeks revealed robust changes in mRNAs associated with oligodendrocyte precursor populations and myelin integrity, including those for transferrin, the atypical oligodendrocyte marker N-myc downstream regulated 1 (Ndrg1), and myelin regulatory factor (Myrf/Mrf), an oligodendrocyte-specific transcription factor with a significant role in oligodendrocyte differentiation/maturation. Western blots conducted after 6-weeks exposure in 3 brain regions (striatum, corpus callosum, pre-frontal cortex) revealed regional differences in the effect of Tat and morphine on Myrf levels, and on levels of myelin basic protein (MBP), whose transcription is regulated by Myrf. Responses included individual and interactive effects. Although baseline and post-treatment levels of Myrf and MBP differed between brain regions, post-treatment MBP levels in striatum and pre-frontal cortex were compatible with changes in Myrf activity. Additionally, the Myrf regulatory ubiquitin ligase Fbxw7 was identified as a novel target in our model. These results suggest that Myrf and Fbxw7 contribute to altered myelin gene regulation in HIV.

Problems undermining the health-related quality of life of people living with HIV in Spain: a qualitative study to inform the development of a novel clinic screening tool

Background

In settings with high antiretroviral therapy coverage, numerous health-related issues continue to undermine the health and health-related quality of life (HRQoL) of people living with HIV (PLHIV). As part of a larger study to develop and validate a new patient-reported outcome measure for use in HIV clinical care in Spain, we sought to identify the most burdensome health-related issues experienced by PLHIV in order to determine which issues should be addressed in the new instrument.

Methods

We conducted a literature review and a qualitative study based on four focus group discussions (FGDs) with key informants in Spain. Participants were selected via purposive sampling. Two FGDs convened 16 expert HIV service providers, and two convened 15 PLHIV with diverse epidemiological profiles. FGDs followed semi-structured interview scripts and incorporated an exercise to prioritise the most critical health-related issues among those named in the discussions. Content analysis was conducted using MAXQDA 12.

Results

The analysis of FGD data identified several broad categories of issues that were perceived to negatively affect PLHIV. The most frequently named issues fell within the categories of social problems; physical symptoms; psychological problems; and sexuality-related problems. Regarding social problems, stigma/discrimination was by far the issue raised the most frequently. In the prioritisation exercise, stigma/discrimination was also ranked as the most burdensome issue by both service providers and PLHIV. Within the physical symptoms category, the issues named most frequently were sleep-related problems, fatigue, physical pain and body fat changes. Regarding psychological problems, FGD participants most commonly spoke of emotional distress in general terms, and also called attention to depression and anxiety. In the prioritisation exercise, both service providers and PLHIV ranked psychological well-being as the second-most important issue following stigma. Sexuality-related problems that were reported included sexually transmitted infections, hormonal problems, lack of libido, and general sexual dissatisfaction.

Conclusions

PLHIV are negatively affected by a wide range of health-related issues. HIV-related stigma and psychological well-being remain major challenges. Identifying and addressing these and other issues in routine clinical care supports healthy aging and may ultimately contribute to better health and HRQoL outcomes in this population.

Sleep Disturbance in the Context of HIV: A Concept Analysis

Due to the differing definitions of the concept of sleep disturbance among people living with human immunodeficiency virus (HIV), reviewers in this area have not reached any firm conclusions. The study aimed to clarify and provide a stronger foundation for the definition of sleep disturbance in the context of HIV to enhance the concept’s development. Following Beth Rodgers’ concept analysis guidelines, two leading databases were searched, and 73 articles were used for this concept analysis. The attributes, surrogate terms, antecedents, and consequences of sleep disturbance have been identified using thematic analysis. In this analysis, two main attributes of sleep disturbance in the context of HIV were identified: a) subjective measures, including reduced total sleep time, difficulty falling asleep, nighttime and early morning awakenings, feeling sleepy and poorly rested after a night’s sleep, frequent arousals, and irritability, and b) objective measures, including changes in sleep architecture and sleep continuity. Five antecedents of sleep disturbance in the context of HIV were identified.

Meanwhile, the consequences of sleep disturbance in HIV are listed based on the frequency the points occur within the reviewed articles. The list is as follows: fatigue and pain; reduced neurocognitive functions; reduced health outcome and quality of life; poor anti-retroviral (ARV) therapy adherence; daytime sleepiness; depression, anxiety, and maladaptive coping; increased disease progression and cardiovascular mortality; and social phobia, living arrangement and sexual dysfunction. An improved understanding of sleep disturbance in the context of HIV will be beneficial in directing analysts to develop research plans. At the same time, the knowledge gaps identified in the analysis provided a solid basis for further study intending to fill in these gaps.

The Interplay Between Neuroinfections, the Immune System and Neurological Disorders: A Focus on Africa

Neurological disorders related to neuroinfections are highly prevalent in Sub-Saharan Africa (SSA), constituting a major cause of disability and economic burden for patients and society. These include epilepsy, dementia, motor neuron diseases, headache disorders, sleep disorders, and peripheral neuropathy. The highest prevalence of human immunodeficiency virus (HIV) is in SSA. Consequently, there is a high prevalence of neurological disorders associated with HIV infection such as HIV-associated neurocognitive disorders, motor disorders, chronic headaches, and peripheral neuropathy in the region. The pathogenesis of these neurological disorders involves the direct role of the virus, some antiretroviral treatments, and the dysregulated immune system. Furthermore, the high prevalence of epilepsy in SSA (mainly due to perinatal causes) is exacerbated by infections such as toxoplasmosis, neurocysticercosis, onchocerciasis, malaria, bacterial meningitis, tuberculosis, and the immune reactions they elicit. Sleep disorders are another common problem in the region and have been associated with infectious diseases such as human African trypanosomiasis and HIV and involve the activation of the immune system. While most headache disorders are due to benign primary headaches, some secondary headaches are caused by infections (meningitis, encephalitis, brain abscess). HIV and neurosyphilis, both common in SSA, can trigger long-standing immune activation in the central nervous system (CNS) potentially resulting in dementia. Despite the progress achieved in preventing diseases from the poliovirus and retroviruses, these microbes may cause motor neuron diseases in SSA. The immune mechanisms involved in these neurological disorders include increased cytokine levels, immune cells infiltration into the CNS, and autoantibodies. This review focuses on the major neurological disorders relevant to Africa and neuroinfections highly prevalent in SSA, describes the interplay between neuroinfections, immune system, neuroinflammation, and neurological disorders, and how understanding this can be exploited for the development of novel diagnostics and therapeutics for improved patient care.

Consensus statement on the role of health systems in advancing the long-term well-being of people living with HIV

Health systems have improved their abilities to identify, diagnose, treat and, increasingly, achieve viral suppression among people living with HIV (PLHIV). Despite these advances, a higher burden of multimorbidity and poorer health-related quality of life are reported by many PLHIV in comparison to people without HIV. Stigma and discrimination further exacerbate these poor outcomes. A global multidisciplinary group of HIV experts developed a consensus statement identifying key issues that health systems must address in order to move beyond the HIV field's longtime emphasis on viral suppression to instead deliver integrated, person-centered healthcare for PLHIV throughout their lives.

Development of a Clinic Screening Tool to Identify Burdensome Health-Related Issues Affecting People Living With HIV in Spain

BACKGROUND

Numerous health-related issues continue to undermine the health and health-related quality of life (HRQoL) of people living with HIV (PLHIV). We developed a clinic screening tool (CST-HIV) for the purpose of identifying these issues in routine specialist clinical care in Spain.

METHODS

We used the following established instrument development procedures: (1) a literature review; (2) four focus group discussions (FGDs), two that convened 16 expert HIV care providers, and two that convened 15 PLHIV; (3) prioritisation, selection and definition of constructs (health-related issues) to include in the CST-HIV and drafting of initial item pool; and (4) a pilot study to analyse psychometric properties and validity of items and to determine which to retain in the final CST-HIV. The FGD interview scripts incorporated an exercise to prioritise the health-related issues perceived to have the greatest negative effect on HRQoL. The online questionnaire used for the pilot study included the pool of CST-HIV items and validated measures of each construct.

RESULTS

We identified 68 articles that reported on factors associated with the HRQoL of PLHIV. The most burdensome health-related issues identified in the FGDs related to stigma, socioeconomic vulnerability, sleep/fatigue, pain, body changes, emotional distress, and sexuality. Based on the literature review and FGD findings, we selected and defined the following constructs to include in the initial CST-HIV: anticipated stigma, emotional distress, sexuality, social support, material deprivation, sleep/fatigue, cognitive problems, and physical symptoms. Two researchers wrote six to eight items for each construct. Next, 18 experts rated 47 items based on their clarity, relevance, and representativeness. Pilot testing was carried out with 226 PLHIV in Spain. We retained 24 items based on empirical criteria that showed adequate psychometric properties. Confirmatory factor analysis confirmed the eight-factor structure with a good fit to the data (RMSEA = 0.035, AGFI = 0.97, CFI = 0.99). We found strong positive correlations between the instrument's eight dimensions and validated measures of the same constructs. Likewise, we found negative associations between the dimensions of the CST-HIV and HRQoL.

CONCLUSION

The CST-HIV is a promising tool for use in routine clinical care to efficiently identify and address health-related issues undermining the HRQoL of PLHIV.

Agreement between self-reported and objective measures of sleep in people with HIV and lifestyle-similar HIV-negative individuals

OBJECTIVES

The aim of this study was to evaluate the agreement between self-reported sleep measures and insomnia with objectively measured sleep parameters in people with HIV (PWH) and HIV-negative individuals.

DESIGN

A cross-sectional analysis of PWH and lifestyle-similar HIV-negative individuals.

METHODS

Self-reported measures included time spent in bed, sleep onset latency and a validated insomnia questionnaire. Objective measures were assessed via 7-days/nights of actigraphy data to determine average and intra-individual variability of several sleep measures (including time spent in bed and onset latency). Spearman's correlation coefficient and Cohen's κ were used to assess the agreement between self-reported and actigraphy-assessed measures. Associations between insomnia and actigraphy-assessed sleep parameters were evaluated using partial least-square discriminant analysis (PLS-DA).

RESULTS

We found fair correlation between self-reported and actigraphy-assessed time spent in bed in 342 PWH (rs = 0.46) and 119 HIV-negative individuals (rs = 0.48). Among PWH, the correlation did not differ by age, education, depressive symptoms and self-reported insomnia (all P > 0.05), but was stronger in men (P = 0.05) and in those with a BMI of at least 25 kg/m2 (P < 0.001). Agreement between self-reported and actigraphy-assessed sleep onset latency was poor in both PWH (κ = 0.002, P = 0.49) and HIV-negative individuals (κ = 0.009, P = 0.65). According to PLS-DA, self-reported insomnia most strongly correlated with intra-individual variability of sleep duration, movement index and efficiency.

CONCLUSION

We report poor-to-fair agreement between self-reported and actigraphy-assessed sleep measures in PWH. Insomnia symptoms correlated with regularity of sleep duration, quality and efficiency. These findings highlight the importance of both patient-reported and objective measures of daily sleep variation, for better understanding sleep disorders in PWH.

Insomnia severity and depressive symptoms in people living with HIV and chronic pain: associations with opioid use

Chronic pain commonly occurs in people living with HIV (PLWH). Many PLWH in the United States obtain opioids for chronic pain management. Whether insomnia severity and depressive symptoms are exacerbated by chronic pain and opioid use in PLWH remains to be determined. This study examined insomnia severity and depressive symptoms in 85 PLWH with chronic pain and 35 PLWH without chronic pain. Among PLWH with chronic pain, reported opioid use was examined in relation to insomnia severity and depressive symptoms. PLWH with chronic pain reported significantly greater insomnia severity (p = .033) and depressive symptoms (p = .025) than PLWH without chronic pain. Among PLWH with chronic pain who reported opioid use (n = 36), insomnia severity was greater compared to those who denied opioid use (n = 49), even after controlling for pain severity and number of comorbidities (p = .026). Greater pain severity was significantly associated with greater insomnia severity (p < .001) and depressive symptoms (p = .048) among PLWH with chronic pain who reported opioid use. These associations were not significant among those PLWH with chronic pain who denied opioid use. Findings suggest that PLWH with chronic pain are likely to experience poor sleep and depressed mood. Furthermore, poor sleep was associated with opioid use among PLWH with chronic pain.

Prevalence of pain in women living with HIV aged 45-60: associated factors and impact on patient-reported outcomes

As the population of women with HIV ages, an increasing proportion are experiencing the menopause, with potential associated pain. Among 844 participants in the Positive Transitions Through the Menopause (PRIME) study (72.3% black African; median age 49 (interquartile-range 47-53) years; 20.9%, 44.0% and 35.1% pre-, peri- and post-menopausal), 376 (44.6%) and 73 (8.7%) reported moderate or extreme pain. Women had been diagnosed with HIV for 14 (9-18) years, 97.7% were receiving antiretroviral therapy and 88.4% had a suppressed viral load. In adjusted ordinal logistic regression, peri-menopausal status (adjusted odds ratio (1.80) [95% confidence interval 1.22-2.67]), current smoking (1.85 [1.11-3.09]), number of comorbid conditions (1.95 [1.64-2.33] /condition) and longer duration of HIV (1.12 [1.00-1.24]/5 years) were independently associated with increased reported pain, whereas being in full-time work (0.61 [0.45-0.83]) and having enough money for basic needs (0.47 [0.34-0.64]) were associated with decreased pain reporting. Increasing pain was independently related to insomnia symptoms (moderate: 2.76 [1.96-3.90]; extreme: 8.09 [4.03-16.24]) and severe depressive symptoms (PHQ4 ≥ 6; moderate: 3.96 [2.50-6.28]; extreme: 9.13 [4.45-18.72]). Whilst our analyses cannot determine the direction of any associations, our findings point to the importance of eliciting a history of pain and addressing symptoms in order to improve wellbeing.

Sleep Disorders in Human Immunodeficiency Virus: A Substudy of the Pharmacokinetics and Clinical Observations in People Over Fifty (POPPY) Study

Background

Self-reported sleep quality is poor in persons with human immunodeficiency virus (PWH), but prior studies commonly used nonspecific questionnaires, investigated only single sleep disorders, or lacked human immunodeficiency virus (HIV)-negative controls. We addressed these limitations in the Pharmacokinetics and Clinical Observations in People Over Fifty (POPPY) Sleep Substudy by assessing PWH and HIV-negative controls for insomnia, restless legs syndrome (RLS), and sleep apnea (SA).

Methods

Previously enrolled POPPY participants coenrolled in this substudy without regard to sleep symptoms. Participants completed validated sleep assessments including the Insomnia Severity Index questionnaire, International Restless Legs Syndrome Study Group questionnaire, and in-home, wrist-worn overnight oximetry. They also completed health-related quality of life questionnaires including 36-item Short Form (SF-36) and Patient-Reported Outcomes Measurement Information System (PROMIS) sleep questionnaires.

Results

We enrolled 357 PWH (246 >50 years of age; 111 between 18 and 50 years) and 126 HIV-negative controls >50 years of age. Among PWH, criteria were met by 21% for insomnia, 13% for RLS, and 6% for SA. Compared with HIV-negative controls, PWH had a higher risk of insomnia (adjusted odds ratio, 5.3; 95% confidence interval, 2.2-12.9) but not RLS or SA. Compared with PWH without insomnia, those with insomnia reported significantly worse scores on all SF-36 and PROMIS components; fewer than 30% reported previous diagnosis or treatment for insomnia.

Conclusions

Insomnia was more common in PWH, associated with worse health-related quality of life, and frequently undiagnosed. Further research should focus on the pathogenesis of insomnia in PWH and the development of effective screening and intervention strategies for this unique population.

A supervised exercise intervention fails to improve subjective and objective sleep measures among older adults with and without HIV

BACKGROUND

Chronic sleep disruption can have significant negative health effects and prior studies suggest that people with HIV (PWH) have disproportionately higher rates of sleep problems.

METHODS

We evaluated baseline sleep of sedentary, older adults (50-75 years) with (n = 28) and without HIV (n = 29) recruited into a 24-week exercise study. Subjective sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI); objective sleep parameters were assessed using wrist-worn actigraphy. Regression models were used to investigate changes in outcomes.

RESULTS

Fifty-seven participants completed the intervention. At baseline, PWH had significantly lower sleep efficiency (88.7 [95% CI 86, 91]%) compared to controls (91.8 [95% CI 91, 93]%; p = 0.02); other sleep measures indicated poorer sleep among PWH but did not reach statistical significance (p ≥ 0.12). Overall, sleep outcomes did not significantly change with the exercise intervention (all p > 0.05). In adjusted analyses, PWH demonstrated a decrease in total sleep time (-22.1 [-43.7, -0.05] p = 0.045) and sleep efficiency (-1.3 [-2.5, -.01], p = 0.03) during the 24 weeks of exercise; these differences were attenuated and no longer significant after adjusting for exercise intensity. At the completion of the intervention, compared to controls, PWH had significantly poorer sleep by PSQI score (2.2 [0.6, 3.8]; p = 0.006) and sleep efficiency (-2.8 [-5.4,-0.2]%; p = 0.04).

CONCLUSIONS

In this study, sleep disturbance was more prevalent in sedentary older PWH compared to uninfected controls. An exercise intervention had minimal effect on sleep impairments among PWH nor controls. Among older adults, interventions beyond cardiovascular and resistance exercise may be needed to significantly alter subjective and objective sleep outcomes.
