Occult hepatitis B virus (HBV) infection is diagnosed when HBc antibodies (HBcAb) and HBV DNA are detectable in serum while hepatitis B surface antigen (HBsAg) is not. This situation has been frequently described in patients with chronic hepatitis C virus (HCV) infection. The objective of this study was to evaluate the prevalence of occult hepatitis B in HIV-HCV-coinfected patients and its clinical relevance in liver histology and viral response after interferon therapy for HCV. A total of 238 HIV-HCV-infected patients,negative for HBsAg, were included. Serum samples were analyzed for the presence of HBV DNA and HBcAb.HBV DNA quantification was determined with the Cobas TaqMan HBV Test (detection limit 6 IU/ml). Data from liver biopsy and laboratory tests were also analyzed. HBcAb resulted in 142 (60%) patients, being the independent associated factors: male gender, previous history of intravenous drug use, age, CD4 count,and HAV antibody presence. Among 90 HBcAb patients that we could analyze, HBV DNA was positive in 15 (16.7% of occult hepatitis B infection in this group, and 6.3% in the whole HIV-HCV cohort studied). No baseline factors, liver histology, or HCV therapy response were related to the presence of HBV DNA. We found that occult hepatitis B is a frequent condition present in at least 6.3% of our HCV-HIV patients and in more than 16% of those with HBcAb. Despite the high prevalence, this phenomenon does not seem to affect the clinical evolution of chronic hepatitis C or modify the viral response to interferon-based HCV therapies

Background: Stavudine (d4T)-containing regimens are associated with a potential for lipoatrophy and dyslipidaemia. We assessed the safety and efficacy of reducing the dose of stavudine compared with switching to tenofovir or maintaining the standard dose of d4T., Methods: Clinically stable HIV-infected patients receiving antiretroviral therapy containing stavudine 40 mg twice daily with a plasma HIV RNA < 200 copies/ml for at least 6 months were randomized to maintain stavudine 40 mg twice daily (d4T40 arm), to reduce to 30 mg twice daily (d4T30 arm), or to switch from d4T to tenofovir (TDF arm)., Results: Fifty-eight (93% male) patients were included: 22 in the d4T40 arm, 19 in the d4T30 arm and 17 in TDF arm. At baseline, median time on d4T was 6 years (interquartile range [IQR] 2.6-7.1), median age 43 years (IQR 36-51) and median CD4+ T-cell count was 587/mm3 (IQR 329-892). At week 24, median limb fat changes (g) were as follows: d4T40 = -182 (95% CI: -469- -5); d4T30 = 527 (95% CI: -343-694); and TDF = 402 (95% CI: 130-835; d4T40 versus TDF, P = 0.0003). Significant differences between median values of laboratory parameters were detected: triglycerides (mg/dl): d4T40 = 19; d4T30 = -23 and TDF = -79 (d4T40 versus TDF, P = 0.03); and total cholesterol (mg/dl): d4t40 = 22, d4T30 = -4, and TDF = -28 (d4T40 versus TDF, P = 0.04). No significant difference was observed in mitochondrial function assessed in peripheral blood mononuclear cells., Conclusions: Although both strategies were associated with a trend toward a decrease in plasma lipids and an increase in body fat, the only significant changes were observed among those who switched to tenofovir.

Contemporary evidence is needed to assess whether the prevalence of depression remains high among people living with HIV in the United Kingdom despite recent efforts to improve patients' mental health, and if depression is negatively associated with individuals' adherence to antiretroviral therapy. In a secondary analysis of a cross-sectional clinic-based survey of alcohol consumption and associated health behaviour among people living with HIV in London, of the 221 respondents, 106 (48%) had poor self-reported adherence to antiretroviral therapy (CASE Index) and 69 (31%) screened positive for depression (PHQ-9). Poor self-reported adherence to ART was 72% higher among participants who screened positive for depression in comparison with participants who screened negative. Respondents who were younger, unemployed, and reported problematic drug use were more likely to screen positive for depression. Screening and management of depression as a part of routine HIV care may support adherence to antiretroviral therapy. [ABSTRACT FROM AUTHOR]

Objectives To develop consensus data statements and clinical recommendations to provide guidance for improving cardiometabolic health outcomes in people with HIV based on the knowledge and experience of an international panel of experts. Methods A targeted literature review including 281 conference presentations, peer-reviewed articles, and background references on cardiometabolic health in adults with HIV published between January 2016 and April 2022 was conducted and used to develop draft consensus data statements. Using a modified Delphi method, an international panel of 16 experts convened in workshops and completed surveys to refine consensus data statements and generate clinical recommendations. Results Overall, 10 data statements, five data gaps and 14 clinical recommendations achieved consensus. In the data statements, the panel describes increased risk of cardiometabolic health concerns in people with HIV compared with the general population, known risk factors, and the potential impact of antiretroviral therapy. The panel also identified data gaps to inform future research in people with HIV. Finally, in the clinical recommendations, the panel emphasizes the need for a holistic approach to comprehensive care that includes regular assessment of cardiometabolic health, access to cardiometabolic health services, counselling on potential changes in weight after initiating or switching antiretroviral therapy and encouraging a healthy lifestyle to lower cardiometabolic health risk. Conclusions On the basis of available data and expert consensus, an international panel developed clinical recommendations to address the increased risk of cardiometabolic disorders in people with HIV to ensure appropriate cardiometabolic health management for this population.

Background: Human genetic contribution to HIV progression remains inadequately explained. The type 1 interferon (IFN) pathway is important for host control of HIV and variation in type 1 IFN genes may contribute to disease progression. This study assessed the impact of variations at the gene and pathway level of type 1 IFN on HIV-1 viral load (VL). Methods: Two cohorts of antiretroviral (ART) naïve participants living with HIV (PLWH) with either early (START) or advanced infection (FIRST) were analysed separately. Type 1 IFN genes (n = 17) and receptor subunits (IFNAR1, IFNAR2) were examined for both cumulated type 1 IFN pathway analysis and individual gene analysis. SKAT-O was applied to detect associations between the genotype and HIV-1 study entry viral load (log10 transformed) as a proxy for set point VL; P-values were corrected using Bonferroni (P < 0.0025). Results: The analyses among those with early infection included 2429 individuals from five continents. The median study entry HIV VL was 14,623 (IQR 3460–45100) copies/mL. Across 673 SNPs within 19 type 1 IFN genes, no significant association with study entry VL was detected. Conversely, examining individual genes in START showed a borderline significant association between IFNW1, and study entry VL (P = 0.0025). This significance remained after separate adjustments for age, CD4+ T-cell count, CD4+/CD8+ T-cell ratio and recent infection. When controlling for population structure using linear mixed effects models (LME), in addition to principal components used in the main model, this was no longer significant (p = 0.0244). In subgroup analyses stratified by geographical region, the association between IFNW1 and study entry VL was only observed among African participants, although, the association was not significant when controlling for population structure using LME. Of the 17 SNPs within the IFNW1 region, only rs79876898 (A > G) was associated with study entry VL (p = 0.0020, beta = 0.32; G associated with higher study entry VL than A) in single SNP association analyses. The findings were not reproduced in FIRST participants. Conclusion: Across 19 type 1 IFN genes, only IFNW1 was associated with HIV-1 study entry VL in a cohort of ART-naïve individuals in early stages of their infection, however, this was no longer significant in sensitivity analyses that controlled for population structures using LME.

Background: Hepatic steatosis is a major cause of chronic liver disease associated with several negative health outcomes. We compared the prevalence of and factors associated with steatosis in people living with and without HIV. Methods: Older (>50 years) and younger (<50 years) people with HIV and older HIV‐negative controls (>50 years) underwent liver transient elastography examination with controlled attenuation parameter (steatosis ≥238 dB/m, moderate/severe steatosis ≥280 dB/m, liver fibrosis ≥7.1 kPa). We compared groups using logistic regression/Chi‐squared/Fisher's exact/Kruskal–Wallis tests. Results: In total, 317 participants (109 older people with HIV; 101 younger people with HIV; 107 HIV‐negative controls) were predominantly white (86%) and male (76%), and 21% were living with obesity (body mass index ≥30 kg/m2). Most (97%) people with HIV had undetectable HIV RNA. The prevalence of fibrosis was 8.4%, 3.0%, and 6.5% in the three groups, respectively (p = 0.26). Fibrosis was predominately (>65%) mild. The prevalence of steatosis was the same in older people with HIV (66.4%) and controls (66.4%) but lower in younger people with HIV (37.4%; p < 0.001). After adjustment, younger people with HIV were less likely to have steatosis (odds ratio [OR] 0.26; 95% confidence interval [CI] 0.14–0.52) than controls, but male sex (OR 2.45; 95% CI 1.20–4.50) and high waist‐to‐hip ratio (OR 3.04; 95% CI 1.74–5.33) were associated with an increased odds of steatosis. We found no association between steatosis and HIV‐related variables. Conclusions: The prevalence of hepatic steatosis and fibrosis was similar between older participants regardless of HIV status. Age, sex, and abdominal obesity, but not HIV‐related variables, were associated with steatosis. Interventions for controlling obesity should be integrated into routine HIV care.

Objectives: Although direct‐acting antivirals (DAAs) can clear HCV in nearly all HIV/HCV‐coinfected individuals, high rates of reinfection may hamper efforts to eliminate HCV in this population. We investigated reinfection after sustained virological response (SVR) in HIV/HCV‐coinfected individuals in Europe. Methods: Factors associated with odds of reinfection by 2 years after SVR in EuroSIDA participants with one or more HCV‐RNA test and 2 years follow‐up were assessed using logistic regression. Results: Overall, 1022 individuals were included. The median age was 50 (interquartile range: 43–54 years), and most were male (78%), injection drug users (52%), and received interferon (IFN)‐free DAAs (62%). By 24 months, 75 [7.3%, 95% confidence interval (CI): 5.7–8.9%] individuals were reinfected. Among individuals treated prior to 2014, 16.1% were reinfected compared with 4.2% and 8.3%, respectively, among those treated during or after 2014 with IFN‐free and IFN‐based therapy. After adjustment, individuals who had started treatment during or after 2014 with IFN‐free or IFN‐based therapy had significantly lower odds of reinfection (adjusted odds ratio = 0.21, 95% CI: 0.11–0.38; 0.43, 95% CI: 0.22–0.83) compared with those who had received therapy before 2014. There were no significant differences in odds of reinfection according to age, gender, European region, HIV transmission risk group or liver fibrosis. Conclusions: Among HIV/HCV‐coinfected individuals in Europe, 7.3% were reinfected with HCV within 24 months of achieving SVR, with evidence suggesting that this is decreasing over time and with use of newer HCV regimens. Harm reduction to reduce reinfection and surveillance to detect early reinfection with an offer of treatment are essential to eliminate HCV. [ABSTRACT FROM AUTHOR]

Successful management of HIV infection as a chronic condition has resulted in a demographic shift where the proportion of people living with HIV (PLWH) older than 50 years is steadily increasing. A dedicated clinic to PLWH older than 50 years was established at Chelsea and Westminster Hospital in January 2009 and then extended to HIV services across the directorate. We report the results of a service evaluation reviewing 10 years of activities of this clinic between January 2009 and 2019. We aimed to estimate the prevalence of major noninfectious comorbidities, polypharmacy (≥5 medications), and multimorbidity (≥2 non-HIV-related comorbidities) and describe algorithms devised for use in HIV outpatient clinics across the directorate. A cohort of 744 PLWH older than 50 years attending this service were analyzed (93% male; mean age of 56 ± 5.5 years; 84% white ethnicity); 97.7% were on antiretroviral treatment and 95.9% had undetectable HIV-RNA at the time of evaluation. The most common comorbidities diagnosed were dyslipidemia (50.1%), hypertension (21.5%), mental health disorders (depression and/or anxiety disorders, 15.7%), osteoporosis (12.2%), obesity (11.9%), chronic kidney disease (7.5%), and diabetes (5.8%). Low vitamin D levels were found in 62% of patients [43% with vitamin D deficiency (<40 mmol/liter) and 57% with vitamin D insufficiency (40–70 mmol/liter)]. The overall prevalence of polypharmacy and multimorbidity was 46.6% and 69.3%, respectively. This study showed significant rates of non-HIV-related comorbidities and polypharmacy in PLWH older than 50 years, leading on to the implementation of clinical care pathways and new joint HIV/specialty clinics (cardiology, nephrology, neurology, metabolic, menopause, and geriatric) to improve prevention, diagnosis, and management of major comorbidities in people aging with HIV.

Cardiovascular disease (CVD) is an important cause of morbidity in people living with HIV (PLWH). We compared the predictive value of HIV-related and traditional CVD risk factors to assess which factors best predict the presence of subclinical coronary atherosclerosis in PLWH. This is a cross-sectional study in PLWH over 50 years of age who performed computed tomography coronary artery calcium (CAC) scoring between 2009 and 2019 at Chelsea and Westminster Hospital. The following outcomes were analyzed: CAC = 0 (no calcification), CAC >0 (any calcification), CAC >100 (moderate calcification), and CAC >400 (severe calcification). Univariate and multivariate logistic regression analyses were performed to assess predictors of coronary calcification. A total of 744 patients were included (mean age 56 ± 5.7 years, 94.8% male, 84% white). A CAC >0 was found in 392 (52.7%), CAC >100 in 90 (12.1%), and CAC >400 in 42 (5.6%) subjects. CAC >100 was strongly associated with hypertension [odds ratio, OR: 2.91, (95% confidence interval: 1.93–4.36), p < .001], dyslipidemia [2.71 (1.81–4.06), p < .001], and diabetes [2.53 (1.29–4.96), p = .01]. Regarding HIV-specific factors, a significant association was found with exposure (>6 years) to protease inhibitors [1.67 (1.06–2.61), p = .05], whereas exposure to tenofovir (>8 years) was negatively associated with CAC >100 [0.54 (0.30–0.98), p = .05]. Despite the high prevalence of hypertension (45.4%) only 21.5% were on antihypertensives, whereas only 29.2% of eligible candidates were receiving lipid-lowering drugs for primary prevention of CVD. Traditional cardiometabolic risk factors remain the strongest predictors of coronary atherosclerosis in PLWH as in the general population. These results underscore the importance of optimizing treatment of hypertension and promoting primary prevention strategies that may be underused in PLWH. [ABSTRACT FROM AUTHOR]

Objectives: Current British HIV Association (BHIVA) guidelines recommend the use of FRAX for the routine assessment of bone fracture risk in people living with HIV over 50 years of age every 3 years. Bone mineral density measurement with dual‐energy X‐ray absorptiometry (DXA) scan is recommended for those with increased fracture risk (FRAX major > 10%). Our objectives were to estimate the prevalence of and risk factors for osteoporosis in a population of PLWH aged > 50 years and assess the utility of FRAX in predicting the presence of DXA‐proven osteoporosis in this cohort. Methods: This was a cross‐sectional study of a cohort of PLWH aged > 50 years attending the Chelsea and Westminster Hospital and who had a DXA scan between January 2009 and December 2018. FRAX scores were calculated using the Sheffield algorithm. Multiple regression models and Cohen's kappa values were used to assess risk factors for osteoporosis and agreement between FRAX and DXA scan results, respectively. Results: In all, 744 patients were included (92.9% male, mean age 56 ± 5 years). The prevalence rates of osteoporosis (at DXA scans) and osteopenia were 12.2% and 63.7%, respectively. FRAX major was > 10% in only two patients, while 90/91 (98.9%) patients with osteoporosis had a normal FRAX score. The presence of osteoporosis was significantly associated with low body mass index and estimated glomerular filtration rate (p < 0.05). Conclusion: Our results indicate that FRAX scores did not predict the presence of osteoporosis in our population of PLWH over 50 years of age and therefore FRAX scores may not be the appropriate tool to define eligibility to perform DXA scans in PLWH.

Objectives: Tenofovir DF (TDF) remains one of the preferred backbone agents for naïve HIV patients starting antiretroviral treatment (ART). The impact of TDF on renal function and metabolic parameters may vary by anchor agent. We investigated the impact of TDF in combination with 3 different integrase inhibitors on tubular and glomerular function, and metabolic parameters in ART-naïve patients. Methods: Sixty patients with normal renal function were randomised (20 per arm) to TDF/emtricitabine (FTC) plus either raltegravir (RAL) (400 mg b.d.), dolutegravir (DTG) or elvitegravir/cobicistat (EVG/c) for 48 weeks. Results: 57 patients completed the study. Significant increases in RBP/creatinine ratio at week 24 were seen in all arms [RAL +4.7 μg/mmol (CI 0.43 to 8.98, p = 0.032); DTG +4.96 μg/mmol (CI 0.77 to 9.15, p = 0.021); EVG/c +6.95 μg/mmol (CI 2.53 to 11.36, p = 0.002)], although this was not sustained to week 48 in the RAL arm. Similar changes across the arms were observed for urinary α1microglobulin (RAL +6.20 mg/L, p = 0.030; DTG +6.30 mg/L, p = 0.025; EVG/c +8.15 mg/L, p = 0.003). Urinary β2microglobulin significantly increased at week 24 with DTG and EVG/c but remained unchanged in the RAL arm. Glomerular filtration measured with CKD-EPI creatinine-cystatin C increased significantly in the RAL arm at week 24 through 48 but declined modestly in other two arms. Total and LDL cholesterol decreased in the RAL arm, but increased in the EVG/c arm, with no significant changes in the DTG arm. Weight increased significantly from baseline with DTG but not RAL or EVG/c. Conclusion: INSTIs in combination with TDF/FTC impact differently on tubular microproteinuria, eGFR, metabolic markers and weight. Use of TDF/FTC with RAL had the least tubular effects and the most favorable metabolic profile. [ABSTRACT FROM AUTHOR]

Objectives: Treatment with bisphosphonates and discontinuation of tenofovir disoproxil fumarate (TDF) are recommended strategies for managing osteoporosis in people living with HIV (PLHIV). This study aimed to compare the effects on bone mineral density (BMD) of TDF discontinuation with and without bisphosphonate therapy in osteoporotic PLHIV. Methods: The present study is a retrospective cohort analysis of dual‐energy X‐ray absorptiometry scan results of PLHIV attending Chelsea and Westminster Hospital HIV clinic between 2009 and 2020. Osteoporotic (T‐score < −2.5) patients with ≥ 6 months' TDF exposure were included. Changes in BMD and T‐scores at the lumbar spine (LS) and femoral neck (FN) were assessed. Results: A total of 84 participants were included, of whom 43 discontinued TDF only (TS) and 41 switched from TDF and received bisphosphonates (TS+): 86.9% were male; 77.4% were white; median (interquartile range, IQR) age was 54.8 (51.0–58.5) years; and median (IQR) TDF exposure was 6.5 (3.5–10.4) years. At a median follow‐up of 2 years after TDF‐discontinuation, mean spine BMD increased significantly in both groups, but bisphosphonate recipients had greater improvements (4.83% vs. 7.79%; P < 0.019); LS T‐scores improved significantly but changes were comparable between groups (TS, 0.5 vs. TS+, 0.6; P = 0.270). At the FN, no significant increases in BMD were observed (TS, 3.05% vs. TS+, 2.71%; P = 0.205); T‐scores significantly improved in bisphosphonate recipients only (+0.2; P = 0.003). A greater proportion recovered from osteoporosis in the TS+ group (34.9% vs. 43.9%), although differences between groups were not significant (P = 0.503). Conclusions: Our real‐world data indicate that although TDF discontinuation significantly improved bone health in osteoporotic PLHIV, combining bisphosphonates with TDF discontinuation resulted in greater improvements in BMD.

Studies conducted in people living with HIV (PLHIV) report high rates of sleep disturbance, without a clear explanation as to cause or effect. Therefore, we proposed use of multiple validated questionnaires that would allow a more comprehensive evaluation of sleep quality in PLHIV. We administered eight validated sleep and wellbeing questionnaires, recording different aspects of sleep in order to provide a comprehensive description of sleep quality, quantity, daytime functioning, wakefulness, and general wellbeing. Associations with demographics and clinical data were analyzed by univariable/multivariable analyses. Of 254 subjects 99% were male (98% men who have sex with men), 88% white, mean age 41 (SD ± 9.9) years, HIV duration eight years (SD ± 6.3), 94% were on antiretroviral therapy, mean CD4 cell count was 724 cells/mm3, 81% had HIV RNA<40 copies/ml, 72% were university educated, and 60% used 'chemsex' drugs. Almost half (45%) reported poor sleep quality, 22% insomnia, 21% daytime sleepiness, and 33% fatigue. As individual factors, HIV duration ≥10 years, anxiety, depression, and recreational drug use were associated with poor quality sleep, fatigue, and poorer functional outcomes (p ≤ 0.05). The prevalence of sleep disturbance was high in our cohort of PLHIV. Sleep disturbance was associated with longer duration of HIV infection, depression, anxiety, and recreational drug use.

We evaluated associations between history of syphilis infection and both cognitive function and depressive symptoms in people living with HIV (PLHIV) and comparable HIV-negative controls. Syphilis serological tests, cognitive function and depression were assessed in PLHIV and controls participating in the Pharmacokinetic and Clinical Observations in People Over Fifty study. Cognitive test scores were converted to demographically adjusted T-scores (mean = 50, SD = 10) and then averaged to obtain a global T-score. Severity of depressive symptoms was assessed via the Patient Health Questionnaire-9. Associations of syphilis with global T-scores and depression were assessed using median regression. The 623 PLHIV and 246 HIV-negative controls were predominantly male (89.3% and 66.5%) with median age (interquartile range [IQR]) of 57 (53-63) and 58 (53-63) years, respectively. PLHIV had lower global cognitive T-scores (median [IQR] 48.7 [45.1, 52.1] versus 50.5 [47.0, 53.9], p < 0.001), more severe depressive symptoms (median [IQR] 4 [1, 10] versus 1 [0, 3], p < 0.001) and were more likely to report history of syphilis infection (22.0% versus 8.1%) than controls. There was no significant association between history of syphilis and global cognitive function in either PLHIV (p = 0.69) or controls (p = 0.10). Participants with a history of syphilis had more severe depressive symptoms (median [IQR] 4 [1, 9] versus 2 [0, 8], p = 0.03); however, the association became non-significant (p = 0.62) after adjusting for HIV status and potential confounders. Despite the higher prevalence of syphilis infection in PLHIV, there was no evidence of an association between history of syphilis infection and impaired cognitive function nor depressive symptoms after accounting for potential confounders.

Objectives: Post-exposure prophylaxis (PEP) for HIV is often poorly tolerated and not completed. Alternative PEP regimens may improve adherence and completion, aiding HIV prevention. We conducted a randomized controlled trial of a maraviroc-based PEP regimen compared with a standard-of-care regimen using ritonavir-boosted lopinavir.Methods: Patients meeting criteria for PEP were randomized to tenofovir disoproxil/emtricitabine (200/245 mg) once daily plus ritonavir-boosted lopinavir (Kaletra ® 400/100 mg) or maraviroc 300 mg twice daily. The composite primary endpoint was completion of 28 days of the allocated PEP regimen without grade 3 or 4 clinical or laboratory adverse events (AEs) related to the PEP medication.Results: Two hundred and thirteen individuals were randomized (107 to maraviroc; 106 to Kaletra ® arm). Follow-up rates were high in both groups. There was no difference in the primary endpoint; 70 (71%) in the maraviroc and 64 (65%) in the Kaletra ® arm ( P  =   0.36) completed PEP without grade 3 or 4 AEs. Discontinuation of PEP was the same (18%) in both groups. There were no grade 3 or 4 clinical AEs in either arm, but more grade 1 or 2 clinical AEs in the Kaletra ® arm (91% versus 70%; P  < 0.001). Antidiarrhoeal medication use was higher in the Kaletra ® arm (67% versus 25%; P  < 0.001). There were no HIV seroconversions in the study period.Conclusions: The completion rate in the absence of grade 3 or 4 AEs was similar with both regimens. Maraviroc-based PEP was better tolerated, supporting its use as an option for non-occupational PEP. [ABSTRACT FROM AUTHOR]

Background: Antiretroviral therapy has changed the natural history of human immunodeficiency virus (HIV) infection in developed countries, where it has become a chronic disease. This clinical scenario requires a new approach to simplify follow-up appointments and facilitate access to healthcare professionals. Methodology: We developed a new internet-based home care model covering the entire management of chronic HIV-infected patients. This was called Virtual Hospital. We report the results of a prospective randomised study performed over two years, comparing standard care received by HIV-infected patients with Virtual Hospital care. HIV-infected patients with access to a computer and broadband were randomised to be monitored either through Virtual Hospital (Arm I) or through standard care at the day hospital (Arm II). After one year of follow up, patients switched their care to the other arm. Virtual Hospital offered four main services: Virtual Consultations, Telepharmacy, Virtual Library and Virtual Community. A technical and clinical evaluation of Virtual Hospital was carried out. Findings: Of the 83 randomised patients, 42 were monitored during the first year through Virtual Hospital (Arm I) and 41 through standard care (Arm II). Baseline characteristics of patients were similar in the two arms. The level of technical satisfaction with the virtual system was high: 85% of patients considered that Virtual Hospital improved their access to clinical data and they felt comfortable with the videoconference system. Neither clinical parameters [level of CD4+ T lymphocytes, proportion of patients with an undetectable level of viral load (p = 0.21) and compliance levels >90% (p = 0.58)] nor the evaluation of quality of life or psychological questionnaires changed significantly between the two types of care. Conclusions: Virtual Hospital is a feasible and safe tool for the multidisciplinary home care of chronic HIV patients. Telemedicine should be considered as an appropriate support service for the management of chronic HIV infection. Trial Registration: Clinical-Trials.gov: NCT01117675. [ABSTRACT FROM AUTHOR]

A standardized questionnaire was used to assess the impact of lipodystrophy (LD) on quality of life (QoL). Eighty-four consecutive asymptomatic human immunodeficiency virus type 1 (HIV-1)-infected outpatients with clinical LD completed a modified version of the Dermatology Life Quality Index (DLQI) survey to measure the impact of body fat changes on their QoL. Body changes influenced dressing for 55 patients (65%), produced feelings of shame for 41 (49%), and disrupted sexual life for 23 (27%). There was a greater impact on the DLQI due to body changes among women, injection drug users, patients with abdominal or breast lipoaccumulation, and patients with a high number of non-LD side effects. Multivariate proportional odds model analysis showed that the severity of non-LD-associated side effects and the presence of breast lipoaccumulation were associated with impaired psychosocial functioning. Specific characteristics of patients, antiretroviral-based side effects, and breast lipoaccumulation exert a greater impact on QoL in HIV-1- infected patients with LD. [ABSTRACT FROM AUTHOR]

Background: Cardiovascular disease (CVD) risk assessment remains a critical step in guiding decisions to initiate primary prevention interventions in people living with HIV (PLWH). Setting: We investigated whether coronary artery calcium (CAC) scoring allowed a more accurate selection of patients who may benefit from statin therapy, compared with current risk assessment tools alone. Methods: Cross-sectional analysis of PLWH over 50 years old who underwent CAC scoring between 2009 and 2019. Framingham Risk score (FRS), QRISK2 and D:A:D scores were calculated for each participant at the time of CAC scoring and statin eligibility determined based on current European guidelines on the prevention of CVD in PLWH. Results: A total of 739 patients were included (mean age 56 ± 5, 92.8% male, 84% white). Among 417 (56.4%) candidates for statin therapy based on FRS ≥10%, 174 (23.5%) had no detectable calcification (CAC = 0). Conversely, 145 (19.6%) patients with detectable calcification (CAC = 0) were identified as low-risk (FRS < 10%). When compared with FRS, CAC scoring reclassified CVD risk in 43.1% of patients, 145 (19.6%) to a higher risk group that could benefit from statin therapy and 174 (23.5%) statin candidates to a lower risk group. QRISK2 and D:A:D scores performed similarly to FRS, underestimating the presence of significant coronary calcification in 21.1% and 24.9% respectively and overestimating risk in 16.9% and 18.8% patients with CAC = 0. Conclusions: Establishing a decision-model based on the combination of conventional risk tools and CAC scoring improves risk assessment and the selection of PLWH who would benefit from statin therapy.

The article presents a study which evaluates the mitochondrial replication, transcription and translation of HIV patients who developed highly active antiretroviral therapy (HAART)-related hyperlactatemia. In this study, mitochondrial parameters in HIV patients were assessed using the quantitative real-time polymerase chain reaction, western blot and spectrophotometry. Results show that mitochondrial parameters in HIV patients decreases on the onset hypelactatemia and improves during recovery.
