RESUMO
INTRODUCTION: Since the advent of HIV pre-exposure prophylaxis (PrEP), stigma has been shown to be a major barrier to its uptake and adherence. It is therefore essential to define the proportion of users who consider that PrEP can negatively impact their image and the factors associated with this perception. METHOD: We performed a multivariable logistic regression on data from the 2567 participants in the ANRS-PREVENIR study who answered the outcome question. RESULTS: Almost one-third of the sample (comprising mostly cisgender men who have sex with men [94.3%]) considered that taking PrEP could give others a negative image of them. Younger participants (adjusted odds ratio [aOR] 0.98; 95% confidence interval [CI] 0.97-0.99) and more psychologically vulnerable participants (i.e., lower self-esteem score [aOR 0.98; 95% CI 0.96-0.99] and higher depression score [aOR 1.02; 95% CI 1.00-1.03]) were also more likely to have this perception. In contrast, participants encouraged to take PrEP by their main partner (aOR 0.67; 95% CI 0.51-0.88) and friends (aOR 0.79; 95% CI 0.66-0.95), and those who protected themselves more because they had knowledge of their most recent sexual partner's HIV status (aOR 0.83; 95% CI 0.69-0.99) and systematic use of PrEP and/or condoms during intercourse in the previous 3 months (aOR 0.80; 95% CI 0.67-0.96) were less likely to have this perception. DISCUSSION: Given the strong interrelation between stigmatization (real or perceived), risky behaviours and adherence, our results emphasize the need for HIV prevention campaigns to promote a positive image of PrEP users. They also show that stigmatization and its effects need to be fully considered to improve HIV prevention offers to current and potential PrEP users who are most likely to be psychologically vulnerable.

BACKGROUND: The FACE-BD cohort is an observational cohort of individuals with bipolar disorders (BD) who benefited from a systematic evaluation with evidence-based treatment recommendations and who were followed-up every year for 3 years in France. The objectives were to describe the lifetime course of BD, associated psychiatric and somatic comorbidities, and cognition profile. This cohort aims to identify clinical/biological signatures of outcomes, trajectories of functioning and transition between clinical stages. This article summarizes 10 years of findings of the FACE-BD cohort. METHOD & RESULTS: We included 4422 individuals, all having a baseline assessment, among which 61.2% had at least one follow-up visit at either one, two or three years. A subsample of 1200 individuals had at least one biological sample (serum, plasma, DNA). Assessments include family history of psychiatric disorders, psychiatric diagnosis, current mood symptoms, functioning, hospitalizations, suicidal attempts, physical health, routine blood tests, treatment history, psychological dimensions, medico-economic data and a cognitive assessment. Studies from this cohort illustrate that individuals with BD display multiple coexistent psychiatric associated conditions including sleep disturbances, anxiety disorders, substance use disorders and suicide attempts as well as a high prevalence of metabolic syndrome. During follow-up, we observed a 55% reduction of the number of days of hospitalization and a significant improvement in functioning. CONCLUSIONS: The FACE-BD cohort provides a strong research infrastructure for clinical research in BD and has a unique position among international cohorts because of its comprehensive clinical assessment and sustainable funding from the French Ministry of Health.

OBJECTIVE: The aim of this study was to compare clinical characteristics and adipose/liver tissue histology analysis in HIV-infected and HIV-uninfected subjects undergoing bariatric surgery. DESIGN: This was a cross-sectional study of HIV-infected subjects undergoing single-port sleeve gastrectomy with prospective enrolment and frequency age (±5 years), sex, and body mass index (BMI, ± 5 kg/m2) matched on HIV-uninfected subjects. METHODS: This study was conducted at a single clinical site at Pitié-Salpêtrière hospital-Paris-France comprising 19 HIV-uninfected and 21 HIV-infected subjects with plasma VL < 20 copies/mL, all with a BMI > 40 kg/m2 or >35 kg/m2 with comorbidities. Histology of subcutaneous and visceral abdominal adipose tissue (SCAT/VAT) and liver biopsies was collected during single-port sleeve gastrectomy. Outcomes included anthropometric characteristics, comorbidities, cardiovascular parameters, adipose tissue, and liver histology. RESULTS: The age of HIV-infected participants was (median, interquartile range IQR) 48 y (42-51), with 76.2% females, a BMI of 41.4 kg/m2 (37.3-44.4), an antiretroviral duration of 16 y (8-21), current integrase strand transfer inhibitor (INSTI)-based regimen in 15 participants and non-INSTI regimen in 6 participants, and a CD4 count of 864/mm3 (560-1066). The age of controls was 43 y (37-51), with 78.9% females and a BMI of 39.2 kg/m2 (36.3-42.6). Anthropometric characteristics, comorbidities, and cardiovascular parameters did not differ according to HIV status and INSTI treatment. The number of macrophage crown-like structures in SCAT was lower in INSTI-treated participants than in HIV-uninfected participants (P = 0.02) and non-INSTI-treated HIV-infected subjects (P = 0.07). Hepatic steatosis and liver disease severity global score were lower in INSTI-treated participants than in non-INSTI-treated HIV-infected participants (P = 0.05 and P = 0.04, respectively). CONCLUSIONS: HIV-infected and HIV-uninfected subjects undergoing bariatric surgery presented a similar profile regarding anthropometric measures, cardiovascular parameters, and comorbidities. However, INSTI-treated participants presented milder SCAT and liver alterations than non-INSTI-treated participants.

The ANRS-PREVENIR (2017-2020) prospective cohort study aims to reduce the number of new HIV infections in the "Ile-de-France" region in France, by enrolling individuals at high risk of HIV infection and proposing daily and on-demand pre-exposure prophylaxis (PrEP). The qualitative component of the ANRS-PREVENIR study aimed to investigate social and relational evolutions associated with PrEP use in men who have sex with men (MSM). In 2018, 12 focus groups with MSM (n = 68) were conducted by a social sciences researcher in Paris. A thematic analysis was performed. Results showed that stigma concerning PrEP use is a complex issue, with various kinds of stigmatization being practiced, sometimes even by the wider MSM population and PrEP users themselves. All types of stigma identified were expressed in forms of verbal abuse which made PrEP use taboo. Inside the wider MSM population a PrEP-user "community" was identified which shared a certain complicity in terms of values and a positive attitude towards PrEP. The emergence of new intragroup and intergroup social norms should be taken into account by policy makers to promote a more positive image of PrEP users.

OBJECTIVES: In most lung screening programmes, only subjects ≥ 55 years old and smoking ≥ 30 pack-years are eligible to undergo chest low-dose computed tomography. Whether the same criteria should apply to people living with HIV (PLHIV) is uncertain, given the increased lung cancer risks associated with immunodeficiency and high rates of smoking. We assessed different outcomes obtained from simulating one round of lung cancer screening in PLHIV using different age and smoking thresholds for eligibility. METHODS: Data from the French Agence Nationale de Recherche sur le SIDA et les Hépatites Virales (ANRS)-CO4 French Hospital Database on HIV (FHDH) cohort of PLHIV and a national representative survey of PLHIV in care in 2011 (the ANRS-VESPA2 [enquête sur les personnes atteintes] study) were used to estimate the maximum proportion of incident lung cancers occurring between 2012 and 2016 that would have potentially been detected by screening in 2011. Secondary outcomes were numbers of eligible subjects in the cohort and numbers of subjects needed to screen (NNS) to detect one lung cancer. RESULTS: Among 77819 PLHIV in 2011 (median age 46 years; 66% men), 285 subjects subsequently developed lung cancer. Adoption of the US Preventive Services Task Force (USPSTF) recommendations (55-80 years; ≥ 30 pack-years) would have detected 31% of lung cancers at most. Lowering the minimum age to 50 and 45 years would have detected 49% and 60% of cancers, respectively, but would have greatly increased the number of eligible subjects and the NNS to detect one case of lung cancer. CONCLUSIONS: Use of the USPSTF criteria would have detected only a minority of lung cancers in a large French cohort of PLHIV in 2011. Screening PLHIV at younger ages (45 or 50 years) and/or the use of lower smoking thresholds (20 pack-years) may be beneficial, despite the consequently higher numbers of eligible subjects and NNS to detect one case of lung cancer, and should be evaluated in future studies.

OBJECTIVES: Given the effectiveness of treatment of HIV, hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, there are considerable benefits associated with determining HIV/HBV/HCV status. We evaluated the feasibility and acceptability of systematic screening and subsequent care in an oral and maxillofacial surgery department. METHODS: The anaesthesiologists proposed screening for HIV, HBV and HCV to all individuals of unknown infection status undergoing surgery between 19 April 2016 and 19 April 2017. The endpoints were the rates of test offer, acceptance/refusal and new diagnoses. Seropositive individuals were referred to infectious disease specialists. Associations between age, sex or surgery type and test offer (eligible individuals) or acceptance/refusal (those offered testing) were investigated. RESULTS: Of the 1407 individuals attending the department, 1322 were eligible for inclusion in the study. Testing was proposed to 899 individuals [68%; 95% confidence interval (CI) 65-71%], 831 of whom accepted the offer (92.4%; 95% CI 90.5-94.1%). Results were obtained for 787 individuals (41 samples were uncollected and three were invalid). Age was the only factor associated with test offer in multivariable analysis [odds ratio (OR) 0.90; 95% CI 0.84-0.97, per additional 10 years], and no factor was associated with acceptance. Of the five, three and eight individuals testing positive for HIV, HBV and HCV, four, two and one patient, respectively, reported prior knowledge of seropositivity. The new diagnosis rate was 0.13% (95% CI 0-0.7%) for HIV and HBV, and 0.89% (95% CI 0.36-1.82%) for HCV [three positive polymerase chain reaction (PCR) tests]. All individuals newly diagnosed with HIV or HCV infection received specific antiviral treatment. CONCLUSIONS: Rates of screening offer and acceptance were high. Substantial screening resources are required to decrease the impact of the hidden epidemics of HIV, HBV and HCV infections.

OBJECTIVES: We examined trends in the incidence rates of invasive cervical cancer (ICC) and in the rate of survival after ICC among women living with HIV (WLHIV) in France and compared them to those of the general population. METHODS: Histologically validated incident cases of ICC in the period 1992-2009 from the French Hospital Database on HIV (FHDH-ANRS CO4) were included in the study. Age-standardized incidence rates were estimated for FHDH and the general population in France for 1992-1996 [pre-combination antiretroviral therapy (cART) period], 1997-2000 (early cART period), 2001-2004 (intermediate cART period), and 2005-2009 (late cART period). Age-standardized incidence ratios (SIRs) were calculated. Five-year survival was compared with that of the general population for ICC diagnosed in 2005-2009 after standardization for age. RESULTS: Among 28 977 WLHIV, 60 incident ICCs were histologically validated. There was a nonsignificant decreasing trend for the incidence across the cART periods (P = 0.07), from 60 to 36/100 000 person-years. The risk of ICC was consistently significantly higher in WLHIV than in the general population; the SIR was 5.4 [95% confidence interval (CI) 3.0-8.9] during the pre-cART period and 3.3 (95% CI 2.2-4.7) in 2005-2009. Survival after ICC did not improve across periods (log-rank P = 0.14), with overall estimated 5-year survival of 78% (95% CI 0.67-0.89%). Five-year survival was similar for WLHIV and the general population for women diagnosed with ICC in 2005-2009, after standardization (P = 0.45). CONCLUSIONS: ICC risk is still more than three times higher in WLHIV than in the general population. Survival after ICC did not improve over time and was similar to that of the general population during the most recent period. Such results call for promotion of the uptake of screening in WLHIV.

OBJECTIVES: High rates of clinical acute rejection after kidney transplantation have been reported in people living with HIV (PLHIV), probably as a consequence of drug interactions. We therefore investigated the incidence of acute rejection within 6 months of transplantation in HIV-infected recipients treated with a protease-inhibitor-free raltegravir-based regimen. METHODS: The Agence Nationale de Recherche sur le Sida et les Hépatites Virales (ANRS) 153 TREVE (NCT01453192) study was a prospective multicentre single-arm trial in adult PLHIV awaiting kidney transplantation, with viral load < 50 HIV-1 RNA copies/mL, CD4 T-cell count > 200 cells/µL, and HIV-1 strains sensitive to raltegravir, aiming to demonstrate 6-month clinical acute rejection rates < 30%. Time to transplantation was compared with that for uninfected subjects matched for age, sex and registration date. RESULTS: In total, 61 participants were enrolled in the study, and 26 underwent kidney transplantation. Two participants experienced clinical acute rejection, corresponding to an estimated clinical acute rejection rate of 8% [95% confidence interval (CI) 2-24%] at 6 and 12 months post-transplantation. HIV infection remained under control in all but one participant, who temporarily stopped antiretroviral treatment. Median time to transplantation was longer in PLHIV than in controls (4.3 versus 2.8 years, respectively; P = 0.002) and was not influenced by blood group. CONCLUSIONS: Acute rejection rates were low after kidney transplantation in PLHIV treated with a raltegravir-based regimen. However, PLHIV have poorer access to transplantation than HIV-uninfected individuals after registration on the waiting list.

OBJECTIVES: Risk factors for loss to follow-up (LTFU) were assessed for people living with HIV (PLHIV) at various reference out-patient clinics (expertise level II) and hospitals (expertise level III) in Mali. METHODS: HIV-1-positive adults starting antiretroviral therapy (ART) in 2006-2013 were eligible for inclusion. Risk factors for LTFU, defined as no visit in the 6 months preceding the last database update, were assessed with the Cox model, taking into account the competing risks of transfer and death. Potential risk factors at the start of ART were demographic and socioeconomic variables, World Health Organization (WHO) stage, CD4 count, period of ART initiation, type of ART, region of care, expertise level and distance from home. RESULTS: We included 9821 PLHIV, 33% of whom were male, starting ART at nine out-patient clinics and seven hospitals [five and two in the capital Bamako and four and five in the 'regions' (i.e. districts outside the capital), respectively] with a median (interquartile range) CD4 count of 153 (56-270) cells/µL. Five-year cumulative incidences of LTFU, transfer and death were 35.2, 9.7 and 6.7%, respectively. People followed at Bamako hospitals > 5 km from home, at regional hospitals or at regional out-patient clinics < 5 km from home were at higher risk of LTFU than people followed at Bamako out-patient clinics, whereas people followed at regional out-patient clinics 5-50 km away from home were at lower risk for LTFU. Deaths were less frequent at hospitals, whether in Bamako or in the regions, than at Bamako out-patient clinics, and more frequent at regional out-patient clinics. CONCLUSIONS: Expertise level and distance to care were associated with LTFU. Stigmatization may play a role for PLHIV living close to the centres in the regions.

BACKGROUND: Individuals presenting for care with severe immunosuppression typically have high plasma HIV viral load (pVL) and may transmit HIV before and after initiation of combination antiretroviral therapies (cART). PATIENTS AND METHODS: Using risk equations and data collected in the IMEA 040 DATA trial on sexual behaviour and pVL level of 84 HIV-infected patients (23 women), we estimated monthly rates of HIV transmission for each virologically unsuppressed participant (pVL >50 copies/mL) who reported sex with HIV-negative or unknown serostatus (HNUS) partners at cART initiation, 24 weeks (W24) and W48 after; rates were considered negligible for other participants. RESULTS: At cART initiation, median pVL was 5.4 log10 copies/mL. The percentage of virologically unsuppressed patients decreased, from 100% at cART initiation to 27% (95% CI 16%-43%) for heterosexuals and 8% (95% CI 2%-22%) for MSM at W48 (P < 0.001). The percentage of patients reporting sex with HNUS partners increased between cART initiation and W48, from 23% (95% CI 10%-42%) to 42% (95% CI 25%-61%) for heterosexuals (P = 0.042) and from 41% (95% CI 21%-64%) to 73% (95% CI 52%-88%) for MSM (P = 0.004). Median monthly HIV transmission rates were 0.0540 (IQR 0.0339-0.0742) for MSM and 0.0018 (IQR 0.0014-0.0191) for heterosexuals at cART initiation, and were reduced by 95% (95% CI 87%-100%) for heterosexuals and 98% (95% CI 95%-100%) for MSM as early as W24. CONCLUSIONS: Risk of onward transmission for severely immunosuppressed individuals is high before and within the first weeks of cART, and persists, at a substantially reduced level, beyond 24 weeks of cART for some individuals. Earlier cART and protecting HIV-negative partners until full viral suppression is achieved could reduce HIV transmission.

Metabolic syndrome (MetS) is highly prevalent in schizophrenia. However very little is known about the time course of MetS and its components. The few longitudinal studies that have been carried out had small sample sizes and a short follow-up. The aim of our study was to evaluate the prevalence of MetS and its components, at baseline and one year later, and to investigate predictors of weight gain (WG) in a cohort of individuals with schizophrenia. We followed 167 schizophrenia patients from the FACE-SZ cohort for one year. The Structured Clinical Interview for DSM-IV (SCID) was used to confirm the diagnosis of schizophrenia. Data on socio-demographic and clinical characteristics, antipsychotic treatment, and comorbidities were collected, and a blood sample was drawn. We found that the prevalence of MetS increased from 21.0% to 26.6% after one year. Patients with baseline depressive symptoms had a 4.5-fold higher risk of WG at the one-year follow-up (p = 0.02) than those without depressive symptoms, after adjusting for confounding variables. WG also correlated with high levels of metabolic parameters and peripheral inflammation. These findings highlight the need to systematically diagnose depression in Schizophrenia. Future studies should determine whether specific pharmacological and non-pharmacological interventions for depression in SZ subjects are effective in preventing rapid high weight gain.

OBJECTIVES: The aim of the study was to determine the time to, and risk factors for, triple-class virological failure (TCVF) across age groups for children and adolescents with perinatally acquired HIV infection and older adolescents and adults with heterosexually acquired HIV infection. METHODS: We analysed individual patient data from cohorts in the Collaboration of Observational HIV Epidemiological Research Europe (COHERE). A total of 5972 participants starting antiretroviral therapy (ART) from 1998, aged < 20 years at the start of ART for those with perinatal infection and 15-29 years for those with heterosexual infection, with ART containing at least two nucleoside reverse transcriptase inhibitors (NRTIs) and a nonnucleoside reverse transcriptase inhibitor (NNRTI) or a boosted protease inhibitor (bPI), were followed from ART initiation until the most recent viral load (VL) measurement. Virological failure of a drug was defined as VL > 500 HIV-1 RNA copies/mL despite ≥ 4 months of use. TCVF was defined as cumulative failure of two NRTIs, an NNRTI and a bPI. RESULTS: The median number of weeks between diagnosis and the start of ART was higher in participants with perinatal HIV infection compared with participants with heterosexually acquired HIV infection overall [17 (interquartile range (IQR) 4-111) vs. 8 (IQR 2-38) weeks, respectively], and highest in perinatally infected participants aged 10-14 years [49 (IQR 9-267) weeks]. The cumulative proportion with TCVF 5 years after starting ART was 9.6% [95% confidence interval (CI) 7.0-12.3%] in participants with perinatally acquired infection and 4.7% (95% CI 3.9-5.5%) in participants with heterosexually acquired infection, and highest in perinatally infected participants aged 10-14 years when starting ART (27.7%; 95% CI 13.2-42.1%). Across all participants, significant predictors of TCVF were those with perinatal HIV aged 10-14 years, African origin, pre-ART AIDS, NNRTI-based initial regimens, higher pre-ART viral load and lower pre-ART CD4. CONCLUSIONS: The results suggest a beneficial effect of starting ART before adolescence, and starting young people on boosted PIs, to maximize treatment response during this transitional stage of development.

Malignancies represent a major cause of morbidity and mortality in human immunodeficiency virus (HIV)-infected patients. The introduction of combined antiretroviral therapy has modified the spectrum of malignancies in HIV infection with a decreased incidence of acquired immunodeficiency syndrome (AIDS) malignancies such as Kaposi's sarcoma and non-Hodgkin's lymphoma due to partial immune recovery and an increase in non-AIDS-defining malignancies due to prolonged survival. Management of HIV-infected patients with cancer requires a multidisciplinary approach, involving both oncologists and HIV physicians to optimally manage both diseases and drug interactions between anticancer and anti-HIV drugs. The French CANCERVIH group presents here a review and an experience of managing non-AIDS malignancies in HIV-infected individuals.

Due to the large production and growing use of titanium dioxide nanoparticles (n-TiO2), their release in the marine environment and their potential interaction with existing toxic contaminants represent a growing concern for biota. Different end-points of genotoxicity were investigated in the European sea bass Dicentrarchus labrax exposed to n-TiO2 (1mgL(-1)) either alone and combined with CdCl2 (0.1mgL(-1)) for 7 days. DNA primary damage (comet assay), apoptotic cells (diffusion assay), occurrence of micronuclei and nuclear abnormalities (cytome assay) were assessed in peripheral erythrocytes and genomic stability (random amplified polymorphism DNA-PCR, RAPD assay) in muscle tissue. Results showed that genome template stability was reduced after CdCl2 and n-TiO2 exposure. Exposure to n-TiO2 alone was responsible for chromosomal alteration but ineffective in terms of DNA damage; while the opposite was observed in CdCl2 exposed specimens. Co-exposure apparently prevents the chromosomal damage and leads to a partial recovery of the genome template stability.

Titanium dioxide nanoparticles (TiO2-NPs) continuously released into waters, may cause harmful effects to marine organisms and their potential interaction with conventional toxic contaminants represents a growing concern for biota. We investigated the genotoxic potential of nanosized titanium dioxide (n-TiO2) (100 µg L(-1)) alone and in combination with CdCl2 (100 µg L(-1)) in Mytilus galloprovincialis after 4 days of in vivo exposure. RAPD-PCR technique and Micronucleus test were used to study genotoxicity. The results showed genome template stability (GTS) being markedly reduced after single exposure to n-TiO2 and CdCl2. Otherwise, co-exposure resulted in a milder reduction of GTS. Exposure to n-TiO2 was responsible for a significant increase of micronucleated cell frequency in gill tissue, while no chromosomal damage was observed after CdCl2 exposure as well as after combined exposure to both substances.

OBJECTIVES: The aim of the study was to assess the impact of rapid and sustained viral control produced by combination antiretroviral therapy (cART) on HIV-associated immune activation and inflammation. METHODS: In this longitudinal observational study, we examined changes in interleukin-6 (IL-6), interferon-γ-inducible protein-10 (IP-10), monokine induced by interferon-γ (MIG) and soluble CD14 (sCD14) levels during 2 years of effective first-line cART. Biomarker levels before and after cART were compared with those observed in healthy subjects, using the Wilcoxon signed rank test. Elevated biomarker levels were defined with respect to values for healthy subject (mean + 2 standard deviations). Factors associated with persistently elevated biomarker levels after 2 years of cART were identified by logistic regression. RESULTS: We included in the study 139 patients with a median HIV-1 RNA level of 4.8 log10 HIV-1 RNA copies/mL and a median CD4 cell count of 294 cells/µL at cART initiation [day 0 (D0)]. At D0, all biomarker levels were higher than in healthy subjects (P < 0.05). After 2 years of cART, IL-6, IP-10 and MIG levels fell significantly, by a median of 0.54, 420 and 1107 pg/mL, respectively (all P < 0.001), and were no longer elevated in > 75% of patients. In contrast, sCD14 levels did not change significantly (0.18 × 10(6) pg/mL; P = 0.102) and remained elevated. Older age was associated with elevated levels of IP-10 [odds ratio (OR) 1.60 per 10 years older; P = 0.047] and MIG (OR 1.92 per 10 years older; P = 0.007) after 2 years of cART. CONCLUSIONS: The rapid and sustained viral suppression produced by first-line cART reduced IL-6, IP-10 and MIG to normal levels, while sCD14, a marker of monocyte activation, remained elevated. High levels of IP-10 and MIG tended to persist in older patients.

Increasing rate of obesity was reported in HIV-infected patients in USA. In France, no data are available to date. Bariatric surgery is the best option for morbid obesity in general population but few data exist in HIV-infected patients. We describe the prevalence of obesity in France in HIV-infected patients. The prevalence of obesity is 15.1% in women and 5.3% in men. Moreover, we described our experience and point of view in the management of HIV infected patients with morbid obesity. Prospective studies are needed for an optimal management of HIV-infected patients with morbid obesity.

OBJECTIVES: The aim of this study was to describe the proportion of liver-related diseases (LRDs) as a cause of death in HIV-infected patients in France and to compare the results with data from our five previous surveys. METHODS: In 2010, 24 clinical wards prospectively recorded all deaths occurring in around 26 000 HIV-infected patients who were regularly followed up. Results were compared with those of previous cross-sectional surveys conducted since 1995 using the same design. RESULTS: Among 230 reported deaths, 46 (20%) were related to AIDS and 30 (13%) to chronic liver diseases. Eighty per cent of patients who died from LRDs had chronic hepatitis C, 16.7% of them being coinfected with hepatitis B virus (HBV). Among patients who died from an LRD, excessive alcohol consumption was reported in 41%. At death, 80% of patients had undetectable HIV viral load and the median CD4 cell count was 349 cells/µL. The proportion of deaths and the mortality rate attributable to LRDs significantly increased between 1995 and 2005 from 1.5% to 16.7% and from 1.2 to 2.0, respectively, whereas they tended to decrease in 2010 to 13% and 1.1, respectively. Among liver-related causes of death, the proportion represented by hepatocellular carcinoma (HCC) dramatically increased from 5% in 1995 to 40% in 2010 (p = 0.019). CONCLUSIONS: The proportion of LRDs among causes of death in HIV-infected patients seems recently to have reached a plateau after a rapid increase during the decade 1995-2005. LRDs remain a leading cause of death in this population, mainly as a result of hepatitis C virus (HCV) coinfection, HCC representing almost half of liver-related causes of death.

OBJECTIVES: Our objectives were to determine the reproducibility of cytological specimen interpretation between two pathologists in human immunodeficiency virus (HIV)-infected women (from the VIHGY, ANRS CO17 study of human papillomavirus genital pathology among HIV-positive women) and to analyse the improvement, if any, between conventional and liquid-based cytology (LBC) interpretations. MATERIALS AND METHODS: A sample of all abnormal and 40% of randomly selected normal Papanicolaou (Pap) tests was randomly ordered and read blindly by a second pathologist using the revised Bethesda terminology 2001. For both conventional and liquid-based preparations, unweighted and Cicchetti-Allison-weighted kappa and their 95% confidence intervals (CIs) were calculated. Kappa values were then compared using the Altman rule to classify the reproducibility of cytological specimen interpretation. RESULTS: Two hundred and seventy-seven conventional Pap tests were reviewed, including 79 abnormal and 10 unsatisfactory results. Overall agreement between the two observers was 78%, with an estimated Cicchetti-Allison-weighted kappa of 0.69 (95%CI, 0.61-0.77). The corresponding values for the 268 LBCs, including 123 abnormal and two unsatisfactory results, were 84% and 0.82 (95%CI, 0.76-0.87), respectively. The reproducibility of LBC interpretations was significantly higher than that of conventional preparations (P = 0.009) and, for both laboratories, the percentages of unsatisfactory results were significantly lower for LBC. CONCLUSION: In HIV-infected women in the combination antiretroviral therapy era, the strength of agreement was better for LBCs than for conventional preparations, with a lower percentage of unsatisfactory results. When available, LBC should be preferred because of its higher reproducibility.

OBJECTIVES: To evaluate whether a dual nucleoside reverse transcriptase inhibitor (NRTI) strategy can control HIV replication in antiviral therapy (ART)-naive HIV-infected patients with a high CD4 cell count and a low viral load (VL). METHODS: This observational study included all HIV-infected treatment-naive patients with a CD4 cell count >300 cells/mm(3), a plasma HIV RNA between 1000 copies/mL and 30,000 copies/mL and wild-type virus who initiated dual NRTI ART between January 2008 and December 2012. HIV RNA and CD4 cell count were assessed at Day 0, Week (W) 4, W12, W24 and W48. The primary endpoint was the proportion of patients with a plasma VL (pVL) <50 copies/mL at W24. RESULTS: Twenty patients were included. The median (IQR) baseline characteristics were: time since HIV diagnosis, 25 months (8-66 months); CD4 cell count, 592 cells/mm(3) (405-798 cells/mm(3)); HIV RNA, 10,395 copies/mL (4106-16,566 copies/mL); and HIV DNA, 464 copies/10(6) peripheral blood mononuclear cells (195-1168 copies/10(6) PBMC). Nineteen patients received tenofovir/emtricitabine and one patient received abacavir/lamivudine. At W12, 88% of the patients with available data (n = 16/18, 95% CI 0.65-0.99) had a pVL <50 copies/mL. Overall, the proportion of patients with a pVL <50 copies/mL was 100% (n = 20/20, 95% CI 0.83-1.0) at W24 and 95% (n = 18/19, 95% CI 0.74-0.99) at W48 (with one patient lost to follow-up and one patient with poor treatment compliance). The median increase in CD4 cells was 83 cells/mm(3) (40-310 cells/mm(3)). There was no discontinuation of antiretroviral therapy for any reason such as lack of efficacy or toxicity. CONCLUSIONS: This pilot study suggests that, in patients with a high CD4 cell count and a low VL, a dual NRTI strategy may represent a potentially effective treatment strategy to control HIV replication. This needs to be confirmed in larger controlled clinical studies.
