RESUMO

BACKGROUND: A persistently low CD4/CD8 ratio has been reported to inversely correlate with the risk of non-AIDS defining cancer in people living with human immunodeficiency virus (HIV; PLWH) efficiently treated by combination antiretroviral therapy (cART). We evaluated the impact of the CD4/CD8 ratio on the risk of Kaposi sarcoma (KS) or non-Hodgkin lymphoma (NHL), still among the most frequent cancers in treated PLWH. METHODS: PLWH from the Collaboration of Observational HIV Epidemiological Research Europe (COHERE) were included if they achieved virological control (viral load ≤ 500 copies/mL) within 9 months following cART and without previous KS/LNH diagnosis. Cox models were used to identify factors associated with KS or NHL risk, in all participants and those with CD4 ≥ 500/mm3 at virological control. We analyzed the CD4/CD8 ratio, CD4 count and CD8 count as time-dependent variables, using spline transformations. RESULTS: We included 56 708 PLWH, enrolled between 2000 and 2014. At virological control, the median (interquartile range [IQR]) CD4 count, CD8 count, and CD4/CD8 ratio were 414 (296-552)/mm3, 936 (670-1304)/mm3, and 0.43 (0.28-0.65), respectively. Overall, 221 KS and 187 NHL were diagnosed 9 (2-37) and 18 (7-42) months after virological control. Low CD4/CD8 ratios were associated with KS risk (hazard ratio [HR] = 2.02 [95% confidence interval {CI } = 1.23-3.31]) when comparing CD4/CD8 = 0.3 to CD4/CD8 = 1) but not with NHL risk. High CD8 counts were associated with higher NHL risk (HR = 3.14 [95% CI = 1.58-6.22]) when comparing CD8 = 3000/mm3 to CD8 = 1000/mm3). Similar results with increased associations were found in PLWH with CD4 ≥ 500/mm3 at virological control (HR = 3.27 [95% CI = 1.60-6.56] for KS; HR = 5.28 [95% CI = 2.17-12.83] for NHL). CONCLUSIONS: Low CD4/CD8 ratios and high CD8 counts despite effective cART were associated with increased KS/NHL risks respectively, especially when CD4 ≥ 500/mm3.

RESUMO

BACKGROUND: Severe bacterial infections are the first cause of morbidity in people with human immunodeficiency virus (PWH). We aimed to assess their incidence and to analyze their determinants. METHODS: We studied human immunodeficiency virus (HIV)-1-infected individuals aged at least 15 years and prospectively followed between 2006 and 2015 in the French Hospital Database on HIV. The Andersen and Gill model was used to calculate the adjusted hazard ratios (HRs), focusing on heavy alcohol use and neutrophil function-altering comorbidities. RESULTS: Of 25 795 participants, 1414 developed 1883 severe bacterial infections. Between 2006 and 2009 and 2013 and 2015, the incidence fell from 13.2 (95% confidence interval [CI], 12.3-14.1) to 7.1 (95% CI, 6.3-7.8) per 1000 person-years. Heavy alcohol use was associated with an increased risk of severe bacterial infection (HR = 1.3, 95% CI = 1.1-1.7 for 40-80 g/day and HR = 1.6, 95% CI = 1.2-2.1 for >80 g/day), as were diabetes, chronic kidney disease, and end-stage liver disease (HR = 1.2, 95% CI = 1.0-1.4 when 1 comorbidity; HR = 2.3, 95% CI = 1.6-3.4 when more than 1 comorbidity), and nonacquired immune deficiency syndrome-defining malignancy (HR = 2.0; 95% CI, 1.6-2.4). CONCLUSIONS: Heavy alcohol use was associated with an increased risk of severe bacterial infection, as were neutrophil function-altering comorbidities. Controlled-drinking approaches should be promoted and comorbidity management should be strengthened in PWH.

RESUMO

We compared access to a kidney transplantation (KT) waiting list (WL) and to KT between people living with HIV (PLHIV) and HIV-uninfected controls. Using the REIN (the national Renal Epidemiology and Information Network registry), we included all PLHIV initiating dialysis in France throughout 2006-2010 and HIV-uninfected controls matched for age, sex, year of dialysis initiation, and the existence of a diabetic nephropathy. Patients were prospectively followed until December 2015. We used a competitive risk approach to assess the cumulative incidence of enrollment on WL and of KT, with death as a competing event (subdistribution hazard ratio adjusted on comorbidities, asdHR). There were 255 PLHIV in the REIN (median age 47 years) of whom 180 (71%) were also found in the French Hospital Database on HIV (FHDH-ANRS CO4) including 126 (70%) known to be on antiretroviral therapy with HIV viral suppression (VS). Five years after dialysis initiation, 65%, and 76%, of treated PLHIV with VS, and of HIV-uninfected controls were enrolled on a WL (asdHR 0.68; 95% CI 0.50-0.91). Access to KT was also less frequent and delayed for treated PLHIV with VS (asdHR 0.75, 95% CI, 0.52-1.10). PLHIV continue to face difficulties to access KT.

RESUMO

Barriers to achieve sustained HIV virological suppression on antiretroviral therapy (ART) jeopardize the success of the 90:90:90 UNAIDS initiative which aims to end the HIV/AIDS epidemic. In France, where access to ART is free and universally available, we analyze the way in which social determinants of health (i.e. cultural, environmental) and economic factors might influence virological outcomes. A cross-sectional study was performed in two hospitals located in Paris area. All consecutive people living with HIV (PLHIV) on ART for at least 6 months attending the outpatient clinics between 01/05/2013 and 31/10/2014 answered an individual score of deprivation, EPICES, retrieving information on health insurance status, economic status, family support and leisure activity. This score varies from 0 to 100 with deprivation state defined above 30.17. Factors associated with HIV viral load >50 copies/ml were assessed by logistic regression modeling with a backward stepwise selection to select the final multivariable model. Sensitivity analyses were performed using two other thresholds for virological non-suppression (100 or 200 copies/ml). Overall, 475 PLHIV were included (53% male, median age 47 years, 66% not born in France mainly in a sub-Saharan African country). Half of French natives and 85% of migrants were classified as deprived. Median duration on ART was 9.7 years with virological suppression in 95.2% of non-deprived participants and in 83.5% of deprived ones (p = 0.001). The final multivariable model retained ART tiredness, younger age, a previous AIDS event and social deprivation (adjusted Odds Ratio, 2.9; 95%CI, 1.2-7.0) as determinants of virological non-suppression but not migration in itself. When using separate components of EPICES score, reporting economic difficulties and non-homeownership were associated with virological non-suppression. In addition to interventions focusing on cultural aspects of migration, social interventions are needed to help people with social vulnerability to obtain sustained responses on ART.

RESUMO

In France, around 25% of the estimated number of people living with HIV are migrants, of whom three quarters are from sub-Saharan Africa (SSA). Our objective was to determine factors associated with virological rebound (VR) at the occasion of a transient stay to the country of origin. HIV-positive migrants from SSA participating to the ANRS-VIHVO adherence study between 2006 and 2009, on effective ART with controlled pre-travel HIV-1 plasma viral load (VL), were included. Outcome was VR, defined as VL ≥ 50 copies/ml at the post-travel visit during the week following the return to France. Among 237 persons (61.6% female, median age 41 years (IQR, 35-47), median time on ART 4.2 years (IQR, 2.2-7.1), 27 (11.4%) experienced VR. The main purpose of the travel was to visit family and median time spent abroad was 5.3 weeks (IQR, 4.1-8.8). The travel was extended longer than anticipated by at least 1 week in 42 individuals (17.7%). In multivariable logistic model, risk factors for VR were male sex [adjusted OR (aOR) 5.1; 95% CI 1.6-16.2)], no employment in France (aOR 2.0; 1.2-3.5), self-reported non-adherence during the trip (aOR 14.9; 4.9-45.9) and PI-containing regimen (aOR 4.6; 1.2-17.6). In another analysis not including self-reported adherence, traveling during Ramadan while respecting the fast (aOR 3.3; 1.2-9.6) and extension of the stay (aOR 3.0; 1.1-7.8) were associated with VR. Virological rebound was partly explained by structural barriers to adherence such as extension of the travel and inadequate management of Ramadan fasting. Individuals' journeys should be carefully planned with health care providers.

RESUMO

Importance: Idiopathic inflammatory myopathies are heterogeneous in their pathophysiologic features and prognosis. The emergence of myositis-specific autoantibodies suggests that subgroups of patients exist. Objective: To develop a new classification scheme for idiopathic inflammatory myopathies based on phenotypic, biological, and immunologic criteria. Design, Setting, and Participants: An observational, retrospective cohort study was performed using a database of the French myositis network. Patients identified from referral centers for neuromuscular diseases were included from January 1, 2003, to February 1, 2016. Of 445 initial patients, 185 patients were excluded and 260 adult patients with myositis who had complete data and defined historical classifications for polymyositis, dermatomyositis, and inclusion body myositis were enrolled. All patients were tested for anti-histidyl-ARN-t- synthetase (Jo1), anti-threonine-ARN-t-synthetase (PL7), anti-alanine-ARN-t-synthetase (PL12), anti-complex nucleosome remodeling histone deacetylase (Mi2), anti-Ku, anti-polymyositis/systemic scleroderma (PMScl), anti-topoisomerase 1 (Scl70), and anti-signal recognition particle (SRP) antibodies. A total of 708 variables were collected per patient (eg, cancer, lung involvement, and myositis-specific antibodies). Main Outcomes and Measures: Unsupervised multiple correspondence analysis and hierarchical clustering analysis to aggregate patients in subgroups. Results: Among 260 participants (163 [62.7%] women; mean age, 59.7 years; median age [range], 61.5 years [48-71 years]), 4 clusters of patients emerged. Cluster 1 (n = 77) included patients who were male, white, and older than 60 years and had finger flexor and quadriceps weakness and findings of vacuolated fibers and mitochondrial abnormalities. Cluster 1 regrouped patients who had inclusion body myositis (72 of 77 patients [93.5%]; 95% CI, 85.5%-97.8%; P < .001). Cluster 2 (n = 91) regrouped patients who were women and had high creatine phosphokinase levels, necrosis without inflammation, and anti-SRP or anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) antibodies corresponding to immune-mediated necrotizing myopathy (53 of 91 [58.2%]; 95% CI, 47.4%-68.5%; P < .001). Cluster 3 (n = 52) regrouped patients who had dermatomyositis rash and anti-Mi2, anti-melanoma differentiation-associated protein 5 (MDA5), or anti-transcription intermediary factor-1γ (TIF1γ) antibodies, mainly corresponding with patients who had dermatomyositis (43 of 52 [82.7%]; 95% CI, 69.7%-91.8%; P < .001). Cluster 4 (n = 40) was defined by the presence of anti-Jo1 or anti-PL7 antibodies corresponding to antisynthetase syndrome (36 of 40 [90.0%]; 95% CI, 76.3%-97.2%; P < .001). The classification of an independent cohort (n = 50) confirmed the 4 clusters (Cohen κ light, 0.8; 95% CI, 0.6-0.9). Conclusions and Relevance: These findings suggest a classification of idiopathic inflammatory myopathies with 4 subgroups: dermatomyositis, inclusion body myositis, immune-mediated necrotizing myopathy, and antisynthetase syndrome. This classification system suggests that a targeted clinical-serologic approach for identifying idiopathic inflammatory myopathies may be warranted.

RESUMO

BACKGROUND: Several retrospective case series have suggested rituximab (RTX) might improve patients with refractory Myasthenia Gravis (MG). OBJECTIVE: In this study, we aimed to evaluate prospectively the efficacy of RTX on muscle function in refractory generalized anti-acetylcholine receptor (AChR) MG patients. METHODS: Enrolled patients received 1 g of RTX at day 0, day 14, and 6-month follow-up (M6). The primary endpoint was improvement of muscle function at 12-month (M12) based on myasthenic muscle score (MMS). Secondary endpoints were an improvement of the MG Foundation of America Postintervention Status (MGFA-PIS), respiratory forced vital capacity, occurrences of acute MG exacerbation and requirement of associated immunosuppressants and immunomodulatory agents. RESULTS: Twelve patients were enrolled, and 11 completed the study. Only a single patient presented an improvement of at least 20 points on MMS at M12, although 2 patients displayed an increase of at least 18 points at M12. MGFA-PIS had improved in 55% of patients by M12. The clinical improvement was not associated with a reduction of immunosuppressant burden. CONCLUSIONS: These results provide data on the effect of RTX in patients with severe, refractory anti-AChR Abs generalized MG. Even though primary outcome was only reached in a single patient at M12, a beneficial effect of RTX on muscle function was seen in half of the patients at M12 and persisted in a third of patients at M18.

RESUMO

Objectives: Inhibition of the organic cation transporter-2 renal tubule transporter by dolutegravir leads to serum creatinine increase. Serum cystatin C is a non-organic cation transporter-2-dependent marker, possibly enabling glomerular filtration rate (GFR) estimation under dolutegravir. Our goal was to evaluate the changes in creatinine- and cystatin C-based estimated GFR values before and after dolutegravir initiation. Methods: Creatinine and cystatin measurements were carried out on frozen plasma samples from HIV-1-infected patients, before and after dolutegravir initiation, between October 2016 and March 2017 at Pitié-Salpêtrière Hospital. CKD-EPI equations were used to estimate mean GFR from creatinine and cystatin C values. Variations were analysed by paired t-test. Results: Forty-four patients were included [median age = 48 years (IQR 36-58) and median CD4 count = 592 cells/mm3 (IQR 388-728)], including 6 ART-naive patients and 38 on switch strategies [72% with viral load <50 copies/mL and median ART duration = 13 years (IQR 5-20)]. Before dolutegravir initiation (median time = 41 days), 19 patients (43%) had creatinine-based estimated GFR <90 mL/min/1.73 m2 and 11 (25%) had cystatin C-based estimated GFR <90 mL/min/1.73 m2. After dolutegravir initiation, serum creatinine values significantly increased (+8.6 µmol/L, 95% CI +5.8; +11.4, P < 0.001) and associated estimated GFR significantly decreased (-7.7 mL/min/1.73 m2, 95% CI -10.4; -5.1, P < 0.001). In contrast, there was no significant change in cystatin C value variation and associated estimated GFR. The same results were observed regardless of renal function at baseline. Conclusions: Creatinine values increased after dolutegravir initiation, whereas no change was observed for cystatin C values. Use of cystatin C may enable better understanding of plasma creatinine fluctuations after dolutegravir initiation, particularly in high-risk renal patients.

RESUMO

Background: Risk factors for progressive multifocal leukoencephalopathy (PML) in individuals with human immunodeficiency virus (HIV) infection are poorly documented in the era of combination antiretroviral therapy (cART). Methods: We studied HIV-1-infected individuals aged ≥15 years who had no history of PML and were prospectively followed up between 1997 and 2011 in the French Hospital Database on HIV (FHDH-ANRS CO4) cohort. Cox models were used to calculate adjusted hazard ratios (HRs), focusing on sub-Saharan origin, suggested to be protective, and recent cART initiation, potentially associated with an increased risk of PML. Results: PML developed in 555 individuals, in 57 during the first 6 months of cART. From 1997-2000 to 2009-2011, the incidence fell from 1.15 (95% confidence interval [CI], .98-1.31) to 0.49 (.37-.61) per 1000 person-years. Sub-Saharan African origin had no clear influence (HR, 0.80; 95% CI, .58-1.11). Compared with men who have sex with men, injection drug users (IDUs) were at higher risk (HR, 1.80 [95% CI, 1.32-2.45] for male and 1.68 [1.13-2.48] for female IDUs). When IDUs were excluded, hepatitis C virus seropositivity was associated with an increased risk (HR, 1.40; 95% CI, 1.02-1.93). Compared with no cART initiation, initiation <6 months previously was associated with PML onset (HR, 4.91; 95% CI, 2.42-9.95). Conclusions: Recent cART initiation is associated with an increased risk of PML, as are injection drug use and hepatitis C virus seropositivity. Sub-Saharan African origin had no protective effect.

RESUMO

BACKGROUND: Viral coinfections might contribute to the increased immune activation and inflammation that persist in antiretroviral treatment (ART)-treated HIV-1 patients. We investigated whether the hepatitis C virus (HCV) coinfection contributes to such alterations by impairing the plasmacytoid dendritic cell (pDC) IFNα/TLR7 pathway in a highly homogeneous group of ART-treated HIV-1-HCV-coinfected patients. METHODS: Twenty-nine HIV-1-infected patients with fully suppressive ART were included, 15 of whom being HCV-coinfected with mild-to-moderate fibrosis and matched for their HIV-1 disease, and 13 control healthy donors. Cellular activation, plasma levels of inflammatory cytokines and pDC transcriptome associated with IFNα/TLR7 pathway were characterized. RESULTS: Higher plasma levels of type-I interferon (IFN)-associated cytokines [interferon gamma-induced protein 10 (IP-10), MIP-1ß, IL-8 and IFN-inducible T-cell alpha chemoattractant) were observed in HIV-1-HCV-coinfected than in HIV-1-monoinfected patients (P = 0.0007, 0.028, 0.028 and 0.035, respectively). The pDCs and T cells displayed a more exhausted (LAG-3+ and CD57+, respectively) phenotype. The pDC IFNα pathway (defined by phosphorylated STAT1 expression) was constitutively activated in all patients, irrespective of HCV coinfection. Expression of interferon-stimulated genes (ISGs) EI2AK2, ISG15, Mx1 and IFI44 was increased in pDCs from HIV-1-HCV-coinfected individuals and was correlated with fibrosis score (Fibroscan, www.echosens.com, Paris, France and aspartate-aminotransferase/platelet-ratio index score, P = 0.026 and 0.019, respectively). Plasma levels of IP-10, STAT1 expression in pDCs and Mx1 mRNA levels in pDCs decreased after interferon-free anti-HCV treatment. CONCLUSION: HCV replication appears to drive increases in type-I IFN-associated inflammation and ISGs expression in pDCs, in association with fibrosis severity in ART-treated HIV-1-infected patients with mild-to-moderate fibrosis. Preliminary results indicate reduction of these alterations with earlier interferon-free anti-HCV treatment in those patients.

RESUMO

BACKGROUND: Hepatitis C virus (HCV) infection is often asymptomatic, and the date of infection is almost impossible to determine. Furthermore, spontaneous clearance (SC) may occur, but little is known about its time of occurrence. METHODS: Data on human immunodeficiency virus (HIV)-HCV coinfected individuals were used to inform a stochastic simulation model of HCV viral load kinetics, alanine aminotransferase (ALT), and HCV antibodies during acute hepatitis C. The dates of diagnosis and potential SC were estimated through a Bayesian approach. Hepatitis C virus diagnosis was assumed to be based on an elevated ALT level detected during a control visit for HIV-infected individuals, which occurred every 3 months (scenario A) or every 6 months (scenario B). RESULTS: We found that HCV diagnosis occurred after a median of 115 days and 170 days of infection in scenarios A and B, respectively. Among spontaneous clearers, SC occurred after a median time of 184 days after infection. Seven percent (scenario B) to 10% (scenario A) of SCs appeared more than 6 months after diagnosis, and 3% (both scenarios) of SCs appeared more than 1 year after diagnosis. CONCLUSIONS: Acute hepatitis C diagnosis occurs late in HIV-HCV coinfected individuals. Screening for HCV in HIV-infected individuals should be performed frequently to reduce delays. Our findings about late occurrence of SC support "wait and see" strategies for treatment initiation from an individual basis. However, early treatment initiation may reduce HCV transmission.

RESUMO

OBJECTIVE: Side effects of antiretroviral therapy (ART) can have a negative impact on health-related quality of life threatening long-term retention in HIV care and adherence to ART. The aim of the French community-based survey EVE was to document personal experiences with side effects, the related physician-patient communication, and solutions found to deal with them. DESIGN: Cross-sectional study of women between September 2013 to September 2014. METHODS: An anonymous online questionnaire included the HIV Symptom Distress Module, which explores 20 symptoms. RESULTS: In all, 301 women on ART participated in the study (median age: 49 years; median duration of ART: 14 years). They reported having experienced a median of 12 symptoms (Q1-Q3: 9-15) during the previous 12 months. Overall, 56% of them reported having found at least a partial solution to dealing with their symptoms. Women reporting financial difficulties were twice less likely to have found solutions to coping with their side effects (AOR: 0.5; 95% CI: 0.3-0.8). Feeling supported by the health-care provider (AOR: 2.1; 95% CI: 1.1-3.9) and being in contact with HIV/AIDS organisations (AOR: 1.9; 95% CI: 1.2-3.2) were positively associated with coping. Seventeen percent reported having modified their ART regimen to improve tolerance, with only 2 in 3 informing their physician afterwards. Reporting financial difficulties and living with more bothersome symptoms increased the risk of ART regimen modification without health-care provider consultation. CONCLUSION: The EVE study has called attention to the large number of side effects experienced by WLWHIV, only half of whom have found self-care strategies to manage their symptoms. Modification of ART regimen by the women themselves was not uncommon.

RESUMO

The aging population of people living with human immunodeficiency virus (HIV) (PLWH) is exposed to a widening spectrum of non-AIDS-defining diseases. Thus, our objective was to compare the health care offered to PLWH according to age. We conducted a multicenter cross-sectional study on PLWH who consulted at one of 59 French HIV reference centers from 15th to 19th October 2012. Using our survey questionnaires, PLWH self-reported the medical care they received, whether or not tied to HIV infection monitoring, during the previous year. A total of 650 PLWH participated in the survey (median age 48 years, Interquartile range (IQR) 40-54), of which 95 were aged 60 years or over (14.5%). Compared to younger PLWH, 60-and-over PLWH were more often under complementary health insurance cover and less socially deprived based on the French EPICES (Evaluation of Precarity and Inequalities in Health Examination Centers) score. The elderly PLWH presented more comorbidities and less coinfections with hepatitis viruses. During health care, therapeutic education was less often offered to older PLWH (14% vs. 26%, p = .01), but this difference was mainly explained by sociodemographic factors and clinical status. Over the previous 6 months, 74% of PLWH who were followed up in hospital had also consulted another doctor, with a mean of 3.75 consultations (±4.18) without difference between age groups. After adjustment for sociodemographic factors and comorbidities, PLWH over 60 years were more likely to have consulted medical specialists as outpatients in the last 6 months (odds ratio [OR] = 2.63 [1.11-6.20]). Whatever their age, 13% of PLWH had been refused care on disclosure of their HIV status, and 27% of PLWH still did not disclose their HIV status to some caregivers. Coordinated health care throughout patients' lives is crucial, as health-care pathways evolve toward outpatient care as the patients get older.

RESUMO

Knowledge about lipid interventions in secondary prevention in HIV-infected individuals is limited; studies are sparse. METHODS: A prospective observational multicenter study enrolled 282 patients on statin 1 month after first acute coronary syndrome (ACS) (95 HIV-infected individuals, 187 HIV-uninfected). Data on fasting lipids (total cholesterol [TC], low-density lipoprotein cholesterol, high-density lipoprotein cholesterol [HDL-C], non-HDL-C, triglycerides, TC/HDL-C ratio) were collected over 3 years. The evolution of lipid concentrations was analyzed using mixed-effects models. Achievement of National Cholesterol Education Program Adult Treatment Panel III lipid goals and prescribed statin intensity was assessed. RESULTS: Mean age of patients was 49.0 years, and 94% were men. Baseline lipids were similar in the 2 groups. Six months after first ACS, less low-density lipoprotein cholesterol reduction was observed in the HIV-infected GROUP (adjusted mean change -10.13; 95% CI -20.63 to 0.37; P=.06) than in the HIV-uninfected group (Adjusted mean change -38.51; 95% CI -46.00 to -31.04; P<.0001) Similar trends were observed for TC and non-HDL-C. After ACS, initial statin prescription for HIV-infected compared with HIV-uninfected individuals was more frequently a moderate-intensity statin (66% vs 45%) and less frequently a high-intensity statin (15% vs 45%). Over 3 years of follow-up, the proportion of HIV-infected patients receiving high-intensity statin remained persistently lower than the proportion observed in the HIV-uninfected group. CONCLUSIONS: In this observational study, HIV-infected individuals after first ACS exhibited worse lipid profiles than controls particularly during the first 6 months while receiving less potent statins. Appropriate statin intensity should be prescribed in HIV-infected individuals with awareness of potential drug-drug interactions.

RESUMO

BACKGROUND: The preferred regimen for HIV post-exposure prophylaxis (PEP) is based mainly on safety and tolerability because it is given to immunocompetent people without HIV infection for a limited time (28 days). The frequency of adverse events (AEs) may be > 60%. Although AEs are generally not severe, they can lead to lack of adherence and failure to complete the regimen. We evaluated the co-formulation elvitegravir, cobicistat, emtricitabine, and tenofovir disoproxil fumarate (Stribild®) prescribed as one pill taken once daily for HIV PEP in terms of tolerability and adherence. METHODS: This was a prospective cohort study conducted in one hospital in Paris (April to December 2015. Each participant receiving the PEP treatment (FTC-150 mg/TDF-245 mg/elvitegravir-200 mg/cobicistat 150 mg once daily) at the pharmacy of the hospital were recruited consecutively. A clinical visit was planned at 8 weeks after sexual exposure. Reminders were sent to participants who missed the appointment. A standardized questionnaire was administered to evaluate completeness and tolerability at week 8. RESULTS: Overall, 284 participants (86% men; 80% MSM; median age 30 years) were prescribed Stribild®; 50 stopped after reassessment of risk. Among 234 participants who effectively received PEP, 215 (92%) completed 28 days of PEP with only three who switched from Stribild® to another PEP because of side effects. More than 60% of participants reported at least one AE, which were mild to moderate. Fatigue, central neurological and abdominal side effects were the most frequently reported. CONCLUSIONS: Stribild® seems to be a good option for HIV PEP due to the easiness of use, the side effects profile and the high completion rate.

RESUMO

BACKGROUND: A low CD4/CD8 ratio in human immunodeficiency virus (HIV)-infected individuals despite effective antiretroviral therapy (ART) reflects ongoing immune activation and has been linked to a higher risk of non-AIDS morbidity and mortality. Our aim was to describe the proportion of individuals with a persistent CD4/CD8 ratio <1 despite long-term viral suppression and to determine associated risk factors. METHODS: This cross-sectional study was conducted in 2012 in a single clinical center. HIV type 1 (HIV-1)-infected individuals were eligible if they had a plasma HIV-1 RNA level <50 copies/mL for at least 2 years on a stable ART regimen. Logistic regression was used to identify risk factors for a persistent CD4/CD8 ratio <1. RESULTS: We enrolled 719 individuals with a median CD4/CD8 ratio of 0.8 (interquartile range [IQR], 0.6-1.1), CD4 and CD8 T-cell counts of 565 (IQR, 435-742) cells/µL and 727 (IQR, 530-991) cells/µL respectively, and viral suppression for 5.4 (IQR, 3.3-9.1) years. Cytomegalovirus (CMV) serology was positive in 564 of 645 individuals (87%). Persistent CD4/CD8 ratio <1 was observed in 471 patients (66%). The following factors were independently associated with a CD4/CD8 ratio <1: CMV seropositivity (odds ratio [OR], 1.9 [95% confidence interval {CI}, 1.1-3.1]), ART initiation before 1997 (OR, 1.9 [95% CI, 1.2-3.0] compared with 2002 or later), a lower CD4 T-cell nadir (OR, 0.7 [95% CI, .7-.8] per log2 increment), and shorter duration of viral suppression (OR, 0.6 [95% CI, .5-.8] per 5 years). CONCLUSIONS: Most HIV-infected individuals with long-term viral suppression still had a CD4/CD8 ratio <1. Early initiation and long-term effective ART appear to improve this ratio. CMV coinfection, which represents a potential target for therapeutic intervention, was strongly associated with a persistently suboptimal CD4/CD8 ratio.

RESUMO

PURPOSE: With DAAs still only being licensed for chronic HCV infection, the ongoing epidemic of acute hepatitis C (AHC) infection among MSM highlights the need to identify factors allowing for optimal HCV treatment outcome. METHODS: 303 HIV-infected patients from 4 European countries with diagnosed acute HCV infection were treated early with pegylated interferon (pegIFN) and ribavirin (RBV) (n = 273) or pegylated interferon alone (n = 30). RESULTS: All patients were male, median age was 39 years. Main routes of transmission were MSM (95%) and IVDU (3%). 69% of patients were infected with HCV GT 1, 4.3% with GT 2, 10.6% with GT 3, 16.1% with GT 4. Overall SVR rate was 69.3% (210/303). RVR (p ≤ 0.001), 48-w treatment duration (p ≤ 0.001) and GT 2/3 (p = 0.024) were significantly associated with SVR. SVR rates were significantly higher in HCV GT 2/3 receiving pegIFN and RBV (33/35) when compared with pegIFN mono-therapy (6/10) (94% vs. 60 % respectively; p = 0.016). In multivariate analysis, pegIFN/RBV combination therapy (p = 0.017) and rapid virological response (RVR) (p = 0.022) were significantly associated with SVR in HCV GT 2/3. In HCV GT 1/4, RVR (p ≤ 0.001) and 48-w treatment duration (p ≤ 0.001) were significantly associated with SVR. CONCLUSIONS: Treatment of AHC GT 2 and 3 infections with pegIFN/RBV is associated with higher SVR rates suggesting different cure rates depending on HCV genotype similar to the genotype effects seen previously in chronic HCV under pegIFN/RBV. With pegIFN/RBV still being the gold standard of AHC treatment and in light of cost issues around DAAs and very limited licensed interferon-free DAA treatment options for chronic HCV GT 3 infection AHC GT 3 patients might benefit most from early interferon-containing treatment.

RESUMO

OBJECTIVE: Anti-synthetase syndrome (anti-SS) is frequently associated with myositis and interstitial lung disease (ILD). We evaluated prospectively, in a multicenter, open-label, phase II study, the efficacy of rituximab on muscle and lung outcomes. METHODS: Patients were enrolled if they were refractory to conventional treatments (prednisone and at least 2 immunosuppressants). They received 1 g of rituximab at D0, D15, and M6. The primary endpoint was muscular improvement based on manual muscular testing (MMT10, Kendall score in 10 muscles) at M12. Secondary endpoints were normalization of creatine kinase (CK) level, ILD improvement based on forced vital capacity and/or diffuse capacity for carbon monoxide, and number and/or doses of associated immunosuppressants. RESULTS: Twelve patients were enrolled, and 10 completed the study. Only 2 patients presented an improvement of at least 4 points on at least two muscle groups (primary end-point). Overall, seven patients had an increase of at least 4 points on MMT10. CK level decreased from 399 IU/L (range, 48-11,718) to 74.5 IU/L (range, 40-47,857). Corticosteroid doses decreased from 52.5 mg/d (range, 10-70) to 9 mg/d (range, 7-65) and six patients had a decrease in the burden of their associated immunosuppressants. At baseline, all 10 patients presented with ILD. At M12, improvement of ILD was observed in 5 out of the 10 patients, stabilization in 4, and worsening in 1. CONCLUSIONS: This pilot study of rituximab treatment in patients with refractory anti-SS provided data on evolution of muscular and pulmonary parameters. Rituximab should now be evaluated in a larger, controlled study for this homogenous group of patients. TRIAL REGISTRATION: Clinicaltrials.gov NCT00774462.

RESUMO

OBJECTIVE: The objective of this study is to study factors associated with HIV-DNA levels in chronically infected patients on long-term suppressive antiretroviral therapy (ART). DESIGN: A cross-sectional, multicentre study of patients receiving ART for more than 3 years, HIV-RNA less than 50 copies/ml for more than 2 years and CD4 cell count more than 350 cells/µl. METHOD: Factors associated with low (<150) or high (>1000), compared with intermediate (150-1000 copies/10 PBMCs) levels of HIV-DNA were investigated using multinomial logistic regression. RESULTS: Five hundred and twenty-two patients who initiated ART during the chronic phase were included (71% male; median peak HIV-RNA: 4.88 log10 copies/ml, CD4 cell count nadir: 222 cells/µl). Median ART duration was 13 years [interquartile range (IQR) 7-17], viral suppression was 5.7 years (IQR 3.9-8.5) and 66% of the patients never experienced ART failure. Median HIV-DNA was 323 copies/10 PBMCs (IQR, 129-717) with low, intermediate and high levels observed in 28.3, 55.4 and 16.3%, respectively. In multivariable analysis, women were more likely to achieve a low level of HIV-DNA. Each additional year with suppressed HIV-RNA increased the likelihood of low level and decreased the likelihood of high level of HIV-DNA. Peak HIV-RNA higher than 5log10 was always associated with a decreased risk of low and an increased risk of high HIV-DNA. For patients with peak HIV-RNA lower than 5log10, past ART failure was associated with high level of HIV-DNA. CONCLUSION: Chronically HIV-infected patients with long-term suppressive ART can achieve low total HIV-DNA but one over six still presented HIV-DNA above 1000 copies/10 PBMCs despite long-term viral suppression.

RESUMO

OBJECTIVE: We aimed at assessing in persons living with HIV with a smoking history an association between lung cancer risk and protease inhibitors exposure, especially ritonavir. DESIGN: A nested case-control study was conducted within the ANRS CO4 FHDH, CO3 Aquitaine and Tenon's Hospital Cohorts. METHODS: Cases and controls were eligible if they were ex-smokers or current smokers at the index date, and had a CD4 cell count reported in the year preceding the index date. Cases were incident cases of lung cancer diagnosed between 1 January 2000 and 31 December 2011. All cancer cases were validated and histological types identified when available. Three controls were randomly selected by incidence density sampling using calendar time as the time axis, with individual matching on cohort, age (± 5 years), route of HIV acquisition, sex and hospital. Analyses were performed using conditional logistic regression adjusted for nadir CD4 cell count and smoking status. Ritonavir and protease inhibitors exposures were represented in separate models using categorical variables (never exposed, ever exposed). Several sensitivity analyses were performed. RESULTS: This study performed in 1447 persons living with HIV with a smoking history (383 lung cancer cases and 1064 control patients) did not evidence any association between lung cancer risk and protease inhibitors exposure including ritonavir. CONCLUSION: These results suggest that the risk of lung cancer is not influenced by pharmacologically induced P450 cytochrome protease inhibitors inhibition among smokers or ex-smokers.
