Perceived HIV-related physical fatigue, sociodemographic characteristics and physical activity: A cross-sectional study.

AIMS AND OBJECTIVES: To get a deeper understanding of correlates of perceived HIV-related fatigue by exploring its associations with sociodemographic characteristics and physical activity level of HIV-infected people. BACKGROUND: Previous studies on HIV-related fatigue have mainly focused on physiological and psychological characteristics, but few have considered its associations with sociodemographic variables. In addition, while physical activity has been found to reduce acute fatigue among HIV-infected people, its links with chronic HIV-related fatigue remain to be explored. DESIGN: The study employed an observational and cross-sectional survey design. The manuscript was organised according to STROBE guidelines. METHOD: A total of 560 people living with HIV in France completed a measure of perceived physical fatigue using the Fatigue Intensity Scale. The predictors targeted sociodemographic characteristics and two measures of individuals' reported level of physical activity. Data were analysed by a stepwise multiple regression model. RESULTS: The results showed that lower age, higher physical activity level and socio-economic status were significantly associated with reduced perceived physical fatigue, explaining 25% of the variance. CONCLUSIONS: The results highlighted the importance of considering sociodemographic and lifestyle characteristics to better characterise HIV-related fatigue, in particular in an era where HIV as a chronic illness challenges questions of quality of life throughout increasingly longer lifespans. RELEVANCE TO CLINICAL PRACTICE: The results of this study have implications for HIV care professionals in terms of improving strategies for managing chronic fatigue or promoting physical activity according to more specific profiles of HIV-infected people.

Exercise stereotypes and health-related outcomes in French people living with HIV: development and validation of an HIV Exercise Stereotypes Scale (HIVESS).

BACKGROUND: The main objective of the current study was to develop and validate a French exercise stereotype scale for people living with HIV (PLHIV) in order to gain visibility to the possible barriers and facilitators for exercise in PLHIV and thus enhance their quality of life. METHODS: A series of four complementary studies was carried out with a total sample of 524 participants to: (a) develop a preliminary version of the HIV Exercise Stereotype Scale (HIVESS) (Stage 1), (b) confirm the factorial structure of the instrument (Stage 2), (c) evaluate the stability of the instrument (Stage 3), and (d) examine the construct and divergent validity of the scale (Stage 4). RESULTS: Results provided support for a 14-item scale with three sub-scales reporting stereotypes related to exercise benefits, exercise risks and lack of capacity for exercise with Cronbach's alphas of .77, .69 and .76 respectively. Results showed good factorial structure, strong reliability and indicators of convergent validity relating to self-efficacy, exercise and quality of life. CONCLUSION: The HIVESS presented satisfactory psychometric properties, constitutes a reliable and valid instrument to measure exercise stereotypes among PLHIV and has applications for future research and clinical practice.

Chemsex in HIV pre-exposure prophylaxis users: Assessment of mood disorders and addictive behavior.

The assessment of mood disorders and addiction linked to the practice of chemsex is of interest given the psychoactive substances used. The aim of this study was to assess risky sexual and addictive behavior to chemsex and related anxiety/depression symptoms in individuals receiving HIV pre-exposure prophylaxis (PrEP). In this cross-sectional study, all adults presenting for PrEP renewal at French sexual health centers were enrolled from January 2018 to March 2019. Participants completed a questionnaire on chemsex (i.e., the use of psychoactive substances before/during sex), including adapted Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) to chemsex addiction (questions of ASSIST were modified to focus on chemsex). Anxiety/depression was assessed with the Hospital Anxiety and Depression Scale. In the last 3 months before enrollment, 39.8% (94/236) of participants reported chemsex. The main psychoactive substances consumed during chemsex were cathinones (74.6%), gamma-hydroxybutyrate (66.3%), and other psychostimulants (60%). The median score of the chemsex-focused ASSIST was 8 [IQR25-75 : 3-15]; 72.2% of participants had a score justifying at least a brief intervention (>4). In multivariate analyses, anxiety and cathinones consumption were associated with an ASSIST score >4: OR 13.65 (95% CI 1.68-662.7), P = 0.0062, and OR 8.468 (95% CI 2.066-43.059), P = 0.0014, respectively. The level of addiction to the practice of chemsex can be difficult to estimate for the user, and the ASSIST makes it possible to evaluate this addiction and to direct the subjects toward specialized consultations of addictology, sexual health, or PrEP renewals. The implementation of the modified ASSIST in these consultations can allow early systematic screening and counseling.

Subclinical cardiac abnormalities in human immunodeficiency virus-infected men receiving antiretroviral therapy.

Although cardiotoxic effects of highly active antiretroviral therapy (HAART) are a growing concern, there is a lack of prospective studies of subclinical involvement of the heart in human immunodeficiency virus (HIV)-infected patients. This study evaluated noninvasively cardiac morphologic characteristics and function in HIV-positive (HIV(+)) men receiving HAART for > or =2 years with no clinical evidence of cardiovascular disease. Echocardiography at rest, including tissue Doppler imaging and exercise testing, were performed in 30 HIV(+) men (age 42.1 +/- 4.7 years, duration of HIV infection 10.4 +/- 4.7 years, duration of HAART 5.3 +/- 2.1 years) and 26 age-matched healthy controls. At rest, HIV(+) patients had similar left ventricular (LV) mass indexed to height(2.7) (40.6 +/- 9.5 vs 37.5 +/- 9.3 g/m; p >0.05), but a higher prevalence of LV diastolic dysfunction (abnormal relaxation or pseudonormal filling pattern in 64% of patients vs 12% of controls; p <0.001). LV systolic function indexes were significantly lower (ejection fraction 60.4 +/- 8.7% vs 66.9 +/- 6.9%; p <0.01, and tissue Doppler imaging peak systolic velocity 11.4 +/- 1.6 vs 13.5 +/- 2.2 cm/s; p <0.001). Pulmonary artery pressure was higher in patients compared with controls (32.1 +/- 5.4 vs 26.1 +/- 6.5 mm Hg; p <0.001). Exercise testing showed decreased exercise tolerance in HIV(+) patients, with no case of myocardial ischemia. In conclusion, subclinical cardiac abnormalities are frequently observed in HIV(+) patients on HAART. The usefulness of systematic noninvasive screening in this population should be considered.

Exercise stereotypes and fatigue in people living with HIV: does self-efficacy play a mediating or a moderating role?

BACKGROUND: Recent research suggests that exercise stereotypes may influence physical activity through ego depletion and internalization mechanisms. The objective of this study was to better understand exercise stereotypes mechanisms among people living with HIV (PLHIV) by further examining the role of exercise self-efficacy and perceived physical fatigue in the relationship between exercise stereotypes and physical activity. METHODS: Three hundred five people living with HIV were recruited to provide data on their stereotypes related to exercise, exercise self-efficacy, perceived physical fatigue as well as their level of physical activity (PA). RESULTS: From the different models tested, the serial mediation model with exercise self-efficacy and perceived physical fatigue as mediators of the relationship between exercise stereotypes and PA, as well as the moderated mediation model with exercise selfefficacy as a moderator of exercise stereotypes and perceived physical fatigue a mediator, provided good fits to the data. However, the moderated mediation model (with indirect associations between negative exercise stereotypes and PA via perceived physical fatigue being moderated by exercise self-efficacy) explained the most variance in PA (R2 = .27). CONCLUSION: The moderated mediation model suggests that exercise stereotypes might influence PA through ego depletion mechanisms and be tempered by exercise self-efficacy.

Early-developed hand osteoarthritis in treated HIV-positive patients: Four cases.

We describe four cases of hand osteoarthritis in patients with HIV infection under antiretroviral treatment. A 36-year-old HIV-infected man came for consultation in 2007 with hand osteoarthritis. He was diagnosed HIV positive by sexual transmission in 1997. A 52-year-old HIV-infected woman came for consultation with hand osteoarthritis started in 2006. She was diagnosed HIV positive in 1986 by sexual transmission. A 57-year-old man presented hand osteoarthritis. This former IV drug user was diagnosed HIV positive in 1989. A 61-year-old HIV-infected man presented with hand osteoarthritis started in 2010. He had been contaminated with HIV in 1990 by sexual transmission. For all patients, there were neither clinical nor biological manifestations suggesting inflammatory arthritis. X-rays showed signs of hand osteoarthritis. CD4 cell count was over 500/mm(3) and the viral load was below 20 copies/mL under treatments. These four cases show osteoarthritis in HIV-infected patients. Hand osteoarthritis did not seem to be linked to aging or to an antiretroviral treatment's side effect, but rather to the HIV infection itself, and it may pass through a metabolic syndrome. We described a possible association between early-developed hand osteoarthritis and HIV-infected patients. Clinicians should consider osteoarthritis when they are confronted with HIV-infected patients with chronic hand pain.

Acute clinical hepatitis by immune restoration in a human immunodeficiency virus/hepatitis B virus co-infected patient receiving antiretroviral therapy.

We describe a human immunodeficiency virus (HIV)-infected patient with chronic active hepatitis B. The patient presented with acute clinical hepatitis during highly active antiretroviral therapy concomitant with immunovirological improvement of HIV infection. The hepatitis resolved within a few weeks despite the pursuit of antiretroviral drugs. Hepatitis B tests, which remained unchanged after two cycles of interferon alfa therapy and continuous administration of lamivudine, were improved with the clearance of hepatitis B virus (HBV) early antigen (HBeAg), the detection of antibody to HBV early antigen (HBeAb) and the undetectability of serum HBV DNA. Several months after this episode, HBV and HIV tests are still controlled.

Long-term monitoring of visceral leishmaniasis in patients with AIDS: relapse risk factors, value of polymerase chain reaction, and potential impact on secondary prophylaxis.

BACKGROUND: Molecular methods have become essential in the diagnosis of visceral leishmaniasis (VL) in patients who have AIDS. The present study aimed at (1) identifying relapse risk factors for VL and (2) assessing the value of long-range routine polymerase chain reaction (PCR) monitoring in such patients, (3) with a view to proposing decision-making elements for discontinuing specific secondary prophylaxis. METHODS: A cohort of 27 HIV-positive patients was prospectively followed up during a period of 5 months to 9 years (median = 51 months) after a first episode of VL. The clinical and biologic follow-up protocol included routine Leishmania detection using peripheral blood and a previously validated PCR method. Quantitative and qualitative variables were statistically analyzed. RESULTS: Sixteen patients relapsed, for a total of 38 relapses. CD4 counts <100 cells/microL and absence of highly active antiretroviral therapy at primary diagnosis and CD4 counts <100 cells/microL during follow-up were the major predictive factors for relapse. No relapse occurred when CD4 counts were >200 cells/microL. The Leishmania PCR assay was positive in all clinical relapses, and its negative predictive value was 100%. CONCLUSIONS: The PCR assay used here proved extremely useful for routine follow-up of VL in patients who had AIDS. Considering CD4 cell counts and Leishmania PCR assays, these results allow defining proposals for discontinuing secondary prophylaxis, and thus optimizing the clinical care of VL in these patients.

Silent cardiac dysfunction and exercise intolerance in HIV+ men receiving combined antiretroviral therapies.

Resting and exercise cardiac function, skeletal muscle oxygenation and whole-body aerobic exercise capacities were evaluated prospectively in cardiac symptom-free HIV men receiving antiretroviral therapies and in healthy controls matched for age, physical activity, smoking and body surface area. HIV patients showed resting cardiac dysfunction, altered cardiac responses to exercise and depressed exercise tolerance. Exercise stroke volume kinetics and muscle oxygenation were impaired in HIV patients, especially in those with resting diastolic dysfunction.

Renal tubular dysfunction associated with tenofovir therapy: report of 7 cases.

We describe 7 cases of renal tubular injury in HIV-infected patients receiving an antiretroviral regimen containing tenofovir. Our patients (5 women and 2 men) developed renal tubular dysfunction, with hypophosphatemia, normoglycemic glycosuria, proteinuria, and decrease of creatinine clearance. The first biologic signs of renal toxicity were observed after duration of tenofovir treatment from 5 weeks to 16 months, and they resolved less than 4 months after discontinuation of tenofovir. Six patients had a low body weight (<60 kg). Five patients received low doses of ritonavir, and 1 received didanosine. In 5 patients, the signs resolved with the discontinuation of only the tenofovir. A renal biopsy performed in 1 patient was consistent with tubulointerstitial injury. Proximal tubulopathy appears to be a rare adverse effect of long-term tenofovir therapy. In patients with low weight or mild preexisting renal impairment, regular monitoring of tubulopathy markers could lead to early detection of this dysfunction.
