Abstract
BACKGROUND Early diagnosis and effective antiretroviral therapy (ART) lead to similar life expectancy in people living with HIV (PLWH) compared to the general population. This population faces problems such as decreased bone mineral density (BMD) and increased fracture risk. The aim of this study was to determine the prevalence of osteoporosis in men aged 50 years and over who were PLWH and to determine risk factors and changes in bone metabolism with bone turnover markers. METHODS 79 male PLWH aged 50 years and over were followed up in our outpatient clinic between May 2021 and October 2021. The patients' demographic, clinical, laboratory, and DEXA data were analyzed. Serum levels of bone turnover markers were measured. RESULTS The prevalence of osteopenia, osteoporosis, and normal BMD was found to be 55.7%, 13.9%, and 30.4%, respectively. A correlation was found between low BMD and low body mass index, elapsed time since diagnosis of HIV infection, high rate of use of ART, and long usage time of tenofovir disoproxil fumarate + protease inhibitor. A one-year increase in HIV infection duration was associated with an increased risk of low BMD by 1.246. CONCLUSION Compared to studies conducted on the general population, the prevalence of osteoporosis in male PLWH aged 50 years and older was two times higher. The limited effect of the duration of ART use on low BMD may be due to the patients' histories of replacement therapy. Therefore, to eliminate the negative effects of ART on BMD, it may be beneficial to start replacement therapy when necessary.

Abstract
BACKGROUND Data on low bone mineral density (BMD) in people living with HIV (PLWH) are mainly derived from younger adults; little is known about how antiretroviral therapy (ART) and alterations in the renal-bone axis relate to BMD in older PLWH. METHODS Cross-sectional study of men > 50 years and post-menopausal women with HIV. Antiretroviral therapy exposure was stratified into four groups based on use of tenofovir disoproxil fumarate (TDF) and protease inhibitors (PI): non-TDF/non-PI, non-TDF/PI, TDF/non-PI, and TDF/PI. Bone mineral density was measured by dual X-ray absorptiometry (DXA). Bone turnover/regulatory markers and renal tubular function were analysed in stored plasma and urine samples. The association of ART exposure and bone/renal biomarkers on BMD was explored using logistic regression models. RESULTS 247 individuals (median [IQR] age 57 [53, 65] years; 47% female; 13% of Black ethnicity; CD4 count 643 [473, 811] cells/mm3; and 98% with HIV RNA < 200 copies/mL) were included. Bone turnover and renal tubular function differed significantly by ART exposure. In analyses adjusted for demographic and traditional renal/bone risk factors, exposure to TDF and PI was associated with a fourfold greater risk of low BMD at the femoral neck and exposure to TDF and/or PI with a threefold greater risk of low BMD at the lumbar spine. The relationship between ART and low BMD was not altered by further adjustment for bone turnover or renal tubular function markers. CONCLUSIONS The associations between low BMD and ART exposure (TDF vs. non-TDF and boosted vs. unboosted third agents) were minimally affected by adjustments for bone and kidney biomarkers.

Abstract
BACKGROUND The study objectives were to measure disability prevalence and severity, and examine disability risk factors, among adults living with HIV in London, United Kingdom (UK). METHODS Self-reported questionnaires were administered: World Health Organization Disability Assessment Schedule 2.0 (WHODAS), HIV Disability Questionnaire (HDQ), Equality Act disability definition (EADD), and demographic questionnaire. We calculated proportion (95% Confidence Interval; CI) of "severe" and "moderate" disability measured using EADD and WHODAS scores ≥2 respectively. We measured disability severity with HDQ domain severity scores. We used demographic questionnaire responses to assess risk factors of "severe" and "moderate" disability using logistic regression analysis, and HDQ severity domain scores using linear regression analysis. RESULTS Of 201 participants, 176 (87.6%) identified as men, median age 47 years, and 194 (96.5%) virologically suppressed. Severe disability prevalence was 39.5% (n = 79/201), 95% CI [32.5%, 46.4%]. Moderate disability prevalence was 70.5% (n = 141/200), 95% CI [64.2%, 76.8%]. Uncertainty was the most severe HDQ disability domain. Late HIV diagnosis was a risk factor for severe disability [Odds Ratio (OR) 2.71; CI 1.25, 5.87]. Social determinants of health, economic inactivity [OR 2.79; CI 1.08, 7.21] and receiving benefits [OR 2.87; CI 1.05, 7.83], were risk factors for "severe" disability. Economic inactivity [OR 3.14; CI 1.00, 9.98] was a risk factor for "moderate" disability. Economic inactivity, receiving benefits, and having no fixed abode were risk factors (P≤0.05) for higher HDQ severity scores in physical, mental and emotional, difficulty with day-to-day activities, and challenges to social participation domains. Personal factors, identifying as a woman and being aged <50 years, were risk factors (P≤0.05) for higher HDQ severity scores in mental and emotional, uncertainty, and challenges with social participation domains. CONCLUSIONS People living with well-controlled HIV in London UK experienced multi-dimensional and episodic disability. Results help to better understand the prevalence, severity, and risk factors of disability experienced by adults living with HIV, identify areas to target interventions, and optimise health and functioning.

Abstract
Background Studies have reported that low bone mineral density (BMD) is prevalent in human immunodeficiency virus (HIV)-infected patients; however, the factors that contribute to HIV-related BMD changes are yet to be fully understood. Due to the application of dual X-ray absorptiometry (DXA) among a select group of hospitals only, the prevalence and risk factors of low BMD in HIV-infected populations have not been intensively investigated in China. Thus, the aim of our study was to investigate the prevalence of and risk factors associated with BMD changes among antiretroviral therapy (ART)-naive HIV-positive patients in China. Methods The assessment of the prevalence of and risk factors associated with BMD changes was conducted among 156 ART-naive HIV-infected patients. Demographic and clinical data, as well as results of fasting blood tests were obtained from patients. Further, all patients underwent DXA scans to determine BMD, which was then used to classify patients with osteopenia/osteoporosis. The risk factors of reduced BMD were then evaluated using binary logistic regression. Results Among the 156 ART-naive HIV-infected participants, osteopenia and osteoporosis were diagnosed in 48.7% (76/156) and 4.5% (7/156) of patients, respectively. The lumbar spine was most likely to have reduced BMD (49.4% [77/156]), and the proportion of osteopenia in the left hip (32.7% [51/156]) was higher than in the right hip (24.4% [38/156]). In the lumbar spine, bone loss rate in the L1 section (60.9% [95/156]) was the most significant (L2, 53.2% [83/156]; L3, 45.5% [71/156]; L4, 52.6% [82/156]). Further analysis showed that, compared with the neck (26.9% [42/156] in the left, 18.6% [29/156] in the right) and the interior (15.4% [24/156] in the left, 13.5% [21/156] in the right), the trochanter had the greatest probability of reduced BMD (46.2% [72/156] in the left, 28.8% [45/156] in the right). In the risk factor analysis, low body mass index (BMI: <18.5 kg/m2) was positively associated with reduced BMD (Exp (B) = 39.743, 95% confidence interval: 3.234–488.399, P = 0.004), and was specifically positively correlated with BMD values at three sites (r = 0.335 at right hip, r = 0.327 at left hip, r = 0.311 at lumbar spine). Conclusion Reduced BMD was found in the majority of ART-naive HIV-infected patients and BMI was identified as an additional risk factor for reduced BMD. Our results show that BMD reduction was simultaneously present in the left hip, right hip, and lumbar spine among nearly one fifth of patients. Our work highlights the importance of closely monitoring BMD in ART-naive patients and provides a foundation for the clinical intervention of bone demineralization in them.

Abstract
Background Almost half of people living with HIV (PLWH) in the USA are over 50 years of age; this is expected to increase to 70% by 2020. Yet, few interventions exist for older PLWH that address psychological and physical symptoms combined, both prevalent in this population. There is a need to find innovative and accessible interventions that can help older PLWH to manage their symptoms. Mind-body interventions, like tai chi/qigong (TCQ), improve both physical and psychological health. TCQ is a series of slow, low-impact meditative movements that integrates breathwork, meditation, and stances. Methods The present study is an exploratory clinical trial that will evaluate the acceptability and feasibility of a 12-week, small group TCQ intervention (n = 24), a sham qigong control condition (n = 24), and a standard of care control condition (n = 24) for older people living with HIV/AIDS. It will also explore any preliminary associations between the TCQ intervention and symptom alleviation. Participants will be recruited from community-based health and social services organizations in Miami, FL, and randomized to one of the 3 conditions. Discussion We will assess feasibility and acceptability through questionnaires and adherence to TCQ. We will assess preliminary associations with symptoms such as depression, anxiety, social support, chronic HIV-related fatigue, and clinical outcomes. These will be described through proportions, means, and changes over time through graphing techniques. Outcomes will be assessed at baseline, at post-intervention, and at 3 months follow-up. These preliminary analyses also will provide information necessary to estimate effect size and power needed for a larger clinical trial. Trial registration ClinicalTrials.gov NCT03840525.

Jingui Shenqi Pills Regulate Bone-Fat Balance in Murine Ovariectomy-Induced Osteoporosis with Kidney Yang Deficiency. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:1517596. [PMID: 32963560 PMCID: PMC7492893 DOI: 10.1155/2020/1517596] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/24/2020] [Revised: 08/16/2020] [Accepted: 08/27/2020] [Indexed: 11/23/2022]
Abstract
Jingui Shenqi Pills (JGSQP) have been a staple of traditional Chinese medicine for thousands of years, used primarily as a treatment for kidney yang deficiency (KYD). In vitro analyses of JGSQP revealed strong induction of osteogenic differentiation and inhibition of adipogenic differentiation in bone-marrow-derived mesenchymal stem/stromal cells. However, the mechanisms by which JGSQP regulate the bone-fat balance in murine ovariectomy-induced osteoporosis with KYD have not been reported. Materials and Methods. Two-month-old female C57BL/6 mice were divided randomly into three groups: those receiving a sham operation (Sham); those undergoing bilateral ovariectomy and selection of KYD syndrome (Model); and those subjected to both bilateral ovariectomy and KYD syndrome selection for 8 weeks, followed by JGSQP treatment for 4 weeks (JGSQP). In the Sham and Model groups, mice were given the same dose of distilled water orally for 4 weeks. Animals from all three groups were euthanised at the 12th week. Vertebral microarchitecture and histomorphology were examined by micro-CT and H&E staining, respectively. In addition, we examined the mRNA expression of Akt, Wnt10b, Osterix (Osx), Fndc5, PPARγ, and Fabp4, as well as the protein of AKT, phosphorylation-AKT (p-AKT), BMP2, COL1A1, and FNDC5. Results. JGSQP treatment improved bone microarchitecture and mitigated histomorphological damage relative to the Model group. The osteoblast number (Ob.N/BS) and area (Ob.S/BS) were increased, whereas adipocyte number (adipocyte/tissue area) and area (adipocyte area/tissue area) were decreased in the JGSQP group. JGSQP treatment reduced the mRNA expression of Akt and adipogenesis-related genes (Fndc5, PPARγ, and Fabp4) while promoting osteogenesis-related genes (Wnt10b and Osx) mRNA expression. Additionally, the expression of p-AKT, BMP2, and COL1A1 proteins was increased and FNDC5 protein expression was decreased after JGSQP treatment. Conclusions. JGSQP treatment reversed murine ovariectomy-induced osteoporosis with KYD by controlling bone-fat balance via AKT pathway.

Abstract
OBJECTIVE To evaluate the psychometric properties of the HIV Disability Questionnaire (HDQ) among people living with HIV (PLHIV) in London, United Kingdom (UK). METHODS This is a cross-sectional measurement study. We recruited and administered the self-reported HDQ, seven criterion measures, and a demographic questionnaire with adults living with HIV accessing HIV care. We determined median and interquartile ranges (IQR) for disability presence, severity and episodic scores (range 0-100). We calculated Cronbach's alpha (α) Kuder-Richardson-20 (KR-20) statistics for disability and episodic scores respectively (internal consistency reliability), smallest detectable change (SDC) for each HDQ severity item and domain (precision), and tested 36 a priori hypotheses assessing correlations between HDQ and criterion scores (construct validity). RESULTS Of N = 243 participants, all were male, median age 40 years, 94% currently taking antiretroviral therapy, and 22% living with ≥2 concurrent health conditions. Median HDQ domain scores ranged from 0 (IQR: 0,7) (difficulties with day-to-day activities domain) to 27 (IQR: 14, 41) (uncertainty domain). Cronbach's alpha for the HDQ severity scale ranged from 0.85 (95% Confidence Interval (CI): 0.80-0.90) in the cognitive domain to 0.93 (95%CI: 0.91-0.94) in the mental-emotional domain. The KR-20 statistic for the HDQ episodic scale ranged from 0.74 (95%CI: 0.66-0.83) in the cognitive domain to 0.91 (95%CI: 0.89-0.94) in the uncertainty domain. SDC ranged from 7.3-15.0 points on the HDQ severity scale for difficulties with day-to-day activities and cognitive symptoms domains, respectively. The majority of the construct validity hypotheses (n = 30/36, 83%) were confirmed. CONCLUSIONS The HDQ possesses internal consistency reliability and construct validity with varied precision when administered to males living with HIV in London, UK. Clinicians and researchers may use the HDQ to measure the nature and extent of disability experienced by PLHIV in the UK, and to inform HIV service provision to address the health-related challenges among PLHIV.

Abstract
Introduction: Besides the well-known increased risk of developing HIV-related infectious comorbidities; compared with the general population, people living with HIV (PLHIV) may also have an increased risk of developing noninfectious comorbidities (NICMs). This is the first study intended to determine the NICMs rates affecting PLHIV who were under cART regimen in Ecuador. Methods: A total of 503 HIV-positive patients were evaluated during the period June 2015-November 2016 and included in a multicenter retrospective, cross-sectional study conducted in seven main government and nongovernment community-based hospitals in Ecuador. Results: The average age of the participants was 39.2±11.9 years old and the majority of them were male (67.2%). The average age at HIV diagnosis was 34.1 years old and cART in average was started 15.9 months after HIV-diagnosis. Recruited patients were receiving cART for an average of 59.2±40.2 months. Only 9.9% (n=50) of the patients did not show any NICMs. Diabetes and pre-diabetes was found in 6% (n=30) and 16.3% (n=82) patients, respectively; however, dyslipidemia and overweight/obesity was frequent, as they affected 41.4% (n=208) and 36.4% (n=183) patients, respectively. Sixty patients (11.9%) were diagnosed with depression and 28.2% (n=142) of the studied subjects were found to have other NICMs. Conclusion: Prevalence of NICMs among subjects under cART was greater than that reported among the Ecuadorian general population, therefore specific public health actions are required to make patients aware of and prevent NICMs among PLHIV in Ecuador.

Abstract
Life expectancy in people living with HIV has increased in the past decades, since the introduction of highly active antiretroviral treatment. Increased survival comes along with new challenges for the HIV physician, as these patients will present comorbidities inherent to ageing that can appear more frequently and at younger age than the general population. The older HIV patient poses a unique challenge, as management should take into account different factors, some related to global ageing such as geriatric syndromes, traditional risk factors, social vulnerability, and age-related diseases, and others related to HIV infection like ART toxicity, drug-drug interactions, immune dysregulation and chronic inflammation. All the above can amount to great polypharmacy and multimorbidity that physician have to be aware of. Little is known about the best screening, management and treatment strategies to improve long-term health outcomes in this ageing population. The following article briefly reviews the main comorbidities that can affect the ageing HIV patient.

Abstract
Context In HIV+ patients, several factors related to patient and antiretroviral therapy (ART) could determine early onset of bone mineral density (BMD) disturbances. Objective Evaluation of bone quality according to gender in patients from the HIV Romanian cohort. Design A cross-sectional study in "Prof. Dr. Matei Balş" National Institute for Infectious Diseases, Bucharest between 2016-2018. Subject and Methods We collected data regarding HIV infection, ART history, viral hepatitis co-infections and we calculated patients body mass index (BMI). CD4 cell count, HIV viral load (VL), vitamin-D levels were determined. Dual-energy X-ray absorptiometry (DXA) scans were used to evaluate BMD. Results We enrolled 97 patients with the median age of 26 years. According to the DXA T-scores, 10 males and 8 females had osteopenia and 4 males and 4 females had osteoporosis. According to Z-scores 2 males and 1 female had osteoporosis. Hip DXA T-scores revealed osteopenia in 6 males and 9 females, whereas T and Z-scores showed osteoporosis in 2 males and 3 females. Lumbar spine (LS) T-score diagnosed osteopenia in 9 males and 6 females, while T and Z-scores revealed osteoporosis in 3 males and females. In males, low T-scores were associated with decreased BMI; low LS DXA Z-scores with low vitamin-D levels; low T and Z-scores and LS-BMD with high VL. Conclusions Evaluating bone quality in patients with a long history of HIV infection, multiple factors should be taken into account.

Abstract
OBJECTIVE Although low bone mineral density (BMD) is prevalent in HIV, changes in BMD over time remain unclear. We aimed to compare rates of, and factors associated with, BMD change between HIV-positive and HIV-negative patients. METHODS In a prospective, 3-year cohort, HIV-positive and HIV-negative patients provided annual demographic and clinical data, fasting bloods, and dual x-ray absorptiometry. Using longitudinal mixed models we compared and determined predictors of rate of change in BMD. RESULTS Of 384 study participants (45.8% HIV positive), 120 contributed two and 264 contributed three BMD measurements. Those with HIV were younger [median interquartile range 39 (34-46) vs. 43 (35-50) years; P = 0.04], more often men (61 vs. 46%; P = 0.003), and less likely Caucasian (61 vs. 82%; P < 0.001). Although BMD was lower in those with HIV, BMD declined in both groups, with nonsignificant between-group difference in rate of BMD change over time. Within the HIV group, starting antiretroviral therapy (ART) within 3 months of enrolment was associated with greater BMD decline at all anatomical sites (all P < 0.001). Age more than 30 years, Caucasian ethnicity, and not being on ART during follow-up were associated with greater decline and higher parathyroid hormone associated with a smaller decline in BMD at the femoral neck. We found no association between BMD change and exposure to tenofovir disoproxil fumarate or protease inhibitors. CONCLUSION We observed no difference in rate of BMD decline regardless of HIV status and in HIV-positive patient, having started ART within the previous 3 months was the only factor associated with greater BMD decline at all three sites.

Abstract
Abstract: Objective Osteoimmunology investigates interactions between skeleton and immune system. In the light of recent discoveries in this field, a new reading register of osteoporosis is actually emerging, in which bone and immune cells are strictly interconnected. Osteoporosis could therefore be considered a chronic immune mediated disease which shares with other age related disorders a common inflammatory background. Here, we highlight these recent discoveries and the new landscape that is emerging. Method Extensive literature search in PubMed central. Results While the inflammatory nature of osteoporosis has been clearly recognized, other interesting aspects of osteoimmunology are currently emerging. In addition, mounting evidence indicates that the immunoskeletal interface is involved in the regulation of important body functions beyond bone remodeling. Bone cells take part with cells of the immune system in various immunological functions, configuring a real expanded immune system, and are therefore variously involved not only as target but also as main actors in various pathological conditions affecting primarily the immune system, such as autoimmunity and immune deficiencies, as well as in aging, menopause and other diseases sharing an inflammatory background. Conclusion The review highlights the complexity of interwoven pathways and shared mechanisms of the crosstalk between the immune and bone systems. More interestingly, the interdisciplinary field of osteoimmunology is now expanding beyond bone and immune cells, defining new homeostatic networks in which other organs and systems are functionally interconnected. Therefore, the correct skeletal integrity maintenance may be also relevant to other functions outside its involvement in bone mineral homeostasis, hemopoiesis and immunity.

Abstract
INTRODUCTION Our aim was to evaluate a community-based exercise (CBE) intervention with the goal of reducing disability and enhancing health for community-dwelling people living with HIV (PLWH). METHODS AND ANALYSIS We will use a mixed-methods implementation science study design, including a prospective longitudinal interrupted time series study, to evaluate a CBE intervention with PLWH in Toronto, Canada. We will recruit PLWH who consider themselves medically stable and safe to participate in exercise. In the baseline phase (0-8 months), participants will be monitored bimonthly. In the intervention phase (8-14 months), participants will take part in a 24-week CBE intervention that includes aerobic, resistance, balance and flexibility exercise at the YMCA 3 times per week, with weekly supervision by a fitness instructor, and monthly educational sessions. In the follow-up phase (14-22 months), participants will be encouraged to continue to engage in unsupervised exercise 3 times per week. Quantitative assessment: We will assess cardiopulmonary fitness, strength, weight, body composition and flexibility outcomes followed by the administration of self-reported questionnaires to assess disability and contextual factor outcomes (coping, mastery, stigma, social support) bimonthly. We will use time series regression analysis to determine the level and trend of outcomes across each phase in relation to the intervention. Qualitative assessment: We will conduct a series of face-to-face interviews with a subsample of participants and recreation providers at initiation, midpoint and completion of the 24-week CBE intervention. We will explore experiences and anticipated benefits with exercise, perceived impact of CBE for PLWH and the strengths and challenges of implementing a CBE intervention. Interviews will be audio recorded and analysed thematically. ETHICS AND DISSEMINATION Protocol approved by the University of Toronto HIV/AIDS Research Ethics Board. Knowledge translation will occur with stakeholders in the form of presentations and publications in open access peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT02794415; Pre-results.

Abstract
OBJECTIVES HIV-infected individuals are at increased risk of incident fractures. Evaluation of trabecular bone micro-architecture is an important tool to assess bone strength, but its use has not yet been reported in middle-aged HIV-infected male individuals. The aim of the study was to compare bone micro-architecture between HIV-infected and HIV-uninfected men. METHODS In this cross-sectional study, 53 HIV-infected male individuals with a mean (± standard deviation) age of 49 ± 9 years who had been receiving antiretroviral therapy including tenofovir disoproxil fumarate (DF) for at least 60 months were compared with 50 HIV-uninfected male controls, matched for age and ethnic origin. We studied the volumetric bone density and micro-architecture of the radius and tibia using high-resolution peripheral quantitative computed tomography (HR-p QCT). RESULTS Volumetric trabecular bone density was 17% lower in the tibia (P < 10(-4) ) and 16% lower in the radius (P < 10(-3) ) in HIV-infected patients compared with controls. By contrast, the cortical bone density was normal at both sites. The tibial trabecular micro-architecture differed markedly between patients and controls: bone volume/total volume (BV/TV) and trabecular number were each 13% lower (P < 10(-4) for both). Trabecular separation and inhomogeneity of the network were 18% and 24% higher in HIV-infected patients than in controls, respectively. The radial BV/TV and trabecular thickness were each 13% lower (P < 10(-3) and 10(-2) , respectively). Cortical thickness was not different between the two groups. CONCLUSIONS The findings of lower volumetric trabecular bone density and disrupted trabecular micro-architectural parameters in middle-aged male HIV-infected treated patients help to explain bone frailty in these patients.

Abstract
With the advent of antiretroviral therapy that can control virus replication below the detection levels of conventional assays, a new clinical landscape of AIDS emerged, in which non-AIDS complications prevail over AIDS-defining conditions. These comorbidities are diverse and affect multiple organs, thus resulting in cardiovascular, kidney, neurocognitive and liver disease, osteopenia/osteoporosis, and cancers. A common feature of these conditions is that they are generally associated with accelerated aging. The mechanism behind these comorbidities is chronic excessive inflammation induced by HIV infection, which persists under antiretroviral therapy. Progressive simian immunodeficiency virus (SIV) infection of nonhuman primates (NHPs) closely reproduces these comorbidities and offers a simplified system in which most of the traditional human risk factors for comorbidities (i.e., smoking, hyperlipidemia) are absent. Additionally, experimental conditions can be properly controlled during a shorter course of disease for SIV infection. As such, NHPs can be employed to characterize new paradigms of AIDS pathogenesis and to test the efficacy of interventions aimed at alleviating non-AIDS-related comorbidities.

Abstract
Since the advent of anti-retroviral therapy, patients with HIV are living longer, and in the year 2015, over half of those infected with the virus will be older than age 50. Moreover, as the general aging population continues to grow, more elderly individuals will become newly infected with HIV. Older patients with HIV contribute to high numbers of initial and rehospitalizations, have longer lengths of hospital day stays, and are at increased risk of death compared to younger patients with HIV and those without HIV. Age-related comorbidities can be exaggerated in HIV-positive patients on and off therapy. Furthermore, signs and symptoms of HIV and AIDS may mimic features seen in the normal aging process of older adults. Internists caring for patients in inpatient settings will be expected to care for and diagnose increasing numbers of older patients with HIV. This will be critical for improving quality of patient care, reducing morbidity and mortality, and managing newly diagnosed patients earlier in the disease course while reducing spread of the virus. Internists should be central leaders in the development of targeted and non-targeted HIV screening efforts in inpatient general medicine wards.

Bone mineral density and inflammatory and bone biomarkers after darunavir-ritonavir combined with either raltegravir or tenofovir-emtricitabine in antiretroviral-naive adults with HIV-1: a substudy of the NEAT001/ANRS143 randomised trial. Lancet HIV 2015; 2:e464-73. [PMID: 26520926 DOI: 10.1016/s2352-3018(15)00181-2] [Citation(s) in RCA: 62] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2015] [Revised: 08/25/2015] [Accepted: 08/25/2015] [Indexed: 02/04/2023]
Abstract
BACKGROUND Osteopenia, osteoporosis, and low bone mineral density are frequent in patients with HIV. We assessed the 96 week loss of bone mineral density associated with a nucleoside or nucleotide reverse transcriptase inhibitor (NtRTI)-sparing regimen. METHODS Antiretroviral-naive adults with HIV were enrolled in 78 clinical sites in 15 European countries into a randomised (1:1), open-label, non-inferiority trial (NEAT001/ANRS143) assessing the efficacy and safety of darunavir (800 mg once per day) and ritonavir (100 mg once per day) plus either raltegravir (400 mg twice per day; NtRTI-sparing regimen) or tenofovir (245 mg once per day) and emtricitabine (200 mg once per day; standard regimen). For this bone-health substudy, 20 of the original sites in six countries participated, and any patient enrolled at one of these sites who met the following criteria was eligible: plasma viral loads greater than 1000 HIV RNA copies per mL and CD4 cell counts of fewer than 500 cells per μL, except in those with symptomatic HIV infection. Exclusion criteria included treatment for malignant disease, testing positive for hepatitis B virus surface antigen, pregnancy, creatinine clearance less than 60 mL per min, treatment for osteoporosis, systemic steroids, or oestrogen-replacement therapy. The two primary endpoints were the mean percentage changes in lumbar spine and total hip bone mineral density at week 48, assessed by dual energy x-ray absorptiometry (DXA) scans. We did the analysis with an intention-to-treat-exposed approach with antiretroviral modifications ignored. The parent trial is registered with ClinicalTrials.gov, number NCT01066962, and is closed to new participants. FINDINGS Between Aug 2, 2010, and April 18, 2011, we recruited 146 patients to the substudy, 70 assigned to the NtRTI-sparing regimen and 76 to the standard regimen. DXA data were available for 129, 121 and 107 patients at baseline, 48 and 96 weeks respectively. At week 48, the mean percentage loss in bone mineral density in the lumbar spine was greater in the standard group than in the NtRTI-sparing group (mean percentage change -2.49% vs -1.00%, mean percentage difference -1.49, 95% CI -2.94 to -0.04; p=0.046). Total hip bone mineral density loss was similarly greater at week 48 in the standard group than in the NtRTI-sparing group (mean percentage change -3.30% vs -0.73%; mean percentage difference -2.57, 95% CI -3.75 to -1.35; p<0.0001). Seven new fractures occurred during the trial (two in the NtRTI-sparing group and five in the standard group). INTERPRETATION A raltegravir-based regimen was associated with significantly less loss of bone mineral density than a standard regimen containing tenofovir disoproxil fumarate, and might be a treatment option for patients at high risk of osteopenia or osteoporosis who are not suitable for NtRTIs such as abacavir or tenofovir alafenamide.

PURPOSE HIV infection has been associated with increased risk of osteoporosis and fragility fractures. Dual-energy X-ray absorptiometry (DXA) is the reference standard to assess bone mineral density (BMD); however, it is not easily accessible in several settings. Heel Quantitative ultrasound (QUS) is a radiation-free, easy-to-perform technique, which may help reducing the need for DXA. METHODS In this cross-sectional study, we used heel QUS (Hologic Sahara(®)) to assess bone status in a cohort of HIV-infected patients. A QUS stiffness index (QUI) threshold >83 was used to identify patients with a low likelihood of osteoporosis. Moreover, we compared QUS results with those of 36 sex- and age-matched HIV-negative controls. RESULTS 244 HIV-positive patients were enrolled. Median heel QUI value was 83 (73-96) vs. 93 (IQR 84-104) in the control group (p = 0.04). 110 patients (45 %) had a QUI value ≤83. Risk factors for low QUI values were age (OR 1.04 per year, 95 % CI 1.01-1.07, p = 0.004), current use of protease inhibitors (OR 1.85, CI 1.03-3.35, p = 0.039), current use of tenofovir (OR 2.28, CI 1.22-4.27, p = 0.009) and the number of risk factors for secondary osteoporosis (OR 1.46, CI 1.09-1.95, p = 0.01). Of note, QUI values were significantly correlated with FRAX score (r = -0.22, p = 0.004). According to EACS guidelines, 45 % of patients had risk factors for osteoporosis which make them eligible for DXA. By using QUS, we may avoid DXA in around half of them. CONCLUSIONS As HIV-positive patients are living longer, the prevalence of osteoporosis is expected to increase over time. Appropriate screening, prevention and treatment are crucial to preserve bone health in this population. The use of screening techniques, such as heel QUS, may help reducing the need for DXA. Further studies are needed to define the diagnostic accuracy of this promising technique in the setting of HIV.

O'Brien KK, Solomon P, Bergin C, O'Dea S, Stratford P, Iku N, Bayoumi AM. Reliability and validity of a new HIV-specific questionnaire with adults living with HIV in Canada and Ireland: the HIV Disability Questionnaire (HDQ). Health Qual Life Outcomes 2015; 13:124. [PMID: 26263898 PMCID: PMC4542093 DOI: 10.1186/s12955-015-0310-9] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2014] [Accepted: 07/20/2015] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND Our aim was to assess internal consistency reliability, construct validity, and test-retest reliability of the HDQ with adults living with HIV in Canada and Ireland. METHODS We recruited adults 18 years of age or older living with HIV from hospital clinics and AIDS service organizations in Canada and Ireland. We administered the HDQ paired with reference measures (World Health Organization Disability Assessment Schedule, SF-36 Questionnaire, Medical Outcomes Study Social Support Survey), and a demographic questionnaire. We calculated HDQ disability presence, severity and episodic scores (scored from 0-100). We calculated Cronbach's alpha and Intraclass Correlation Coefficients (ICC) (Canada only) for the disability severity and episodic scores and considered coefficients >0.80 and >0.70 as acceptable, respectively. To assess construct validity, we tested 40 a priori hypotheses of correlations between scores on the HDQ and reference measures and two known group hypotheses comparing HDQ presence and severity scores based on age and comorbidity. We considered acceptance of at least 75% of hypotheses as demonstrating support for construct validity. RESULTS Of the 235 participants (139 Canada; 96 Ireland), the majority were men (74% Ireland; 82% Canada) and were taking antiretroviral therapy (88% Ireland; 91% Canada). Compared with Irish participants, Canadian participants were older (median age: 48 versus 41 years) and reported living with a higher median number of comorbidities (4 versus 1). Cronbach's alpha for Irish and Canadian participants were 0.97 (95% confidence interval (CI): 0.97-0.98) and 0.96 (95 % CI: 0.95-0.98), respectively, for the severity scale and 0.98 (95 % CI: 0.97-0.98) and 0.96 (95 % CI: 0.95-0.98), respectively, for the episodic scale. Of the 40 construct validity correlation hypotheses, 32 (80%) and 22 (55%) were supported among the Canadian and Irish samples respectively; both (100%) known group hypotheses were also supported. ICC values for Canadian participants ranged from 0.80 (95 % CI: 0.71, 0.86) in the cognitive domain to 0.89 (95 % CI: 0.83, 0.92) in the social inclusion domain. CONCLUSIONS The HDQ demonstrates internal consistency reliability and a variable degree of construct validity when administered to adults living with HIV in Canada and Ireland. The HDQ demonstrates test-retest reliability when administered to adults with HIV in Canada. Further validation of the HDQ outside of Canada is needed.

Abstract
The 2014 International Symposium on HIV and Emerging Infectious Diseases (ISHEID) provided a forum for investigators to hear the latest research developments in the clinical management of HIV and HCV infections as well as HIV cure research. Combined anti-retroviral therapy (c-ART) has had a profound impact on the disease prognosis and transformed this infection into a chronic disease. However, HIV is able to persist within the infected host and the pandemic is still growing. The main 2014 ISHEID theme was, hence "Together for a world without HIV and AIDS". In this report we not only give details on this main topic but also summarize what has been discussed in the areas of HCV coinfection and present a short summary on currently emerging viral diseases.
