RESUMEN

BackgroundSome migrant men who have sex with men (MSM) acquire HIV in France.AimsWe investigated, in migrant MSM receiving HIV care in France, the (i) rate of post-migration-HIV acquisition in France, (ii) delay between arrival and HIV acquisition and (iii) factors affecting HIV acquisition within 1 year after migration.MethodsThis cross-sectional study focused on ≥ 18-year-old MSM born outside France, receiving HIV care in the Paris region. Information on migration history, socioeconomic condition, sexual activity, and health was collected in May 2021-June 2022 through self-administered questionnaires and medical records. Post-migration-HIV-acquisition rate and delay between arrival in France and HIV acquisition were estimated from biographical data and CD4+ T-cell counts. Predictors of HIV acquisition within 1 year after migration were determined using logistic regression.ResultsOverall post-migration HIV-acquisition rate was 61.7% (715/1,159; 95%CI: 61.2-62.2), ranging from 40.5% (95%CI: 39.6-41.6) to 85.4% (95%CI: 83.9-86.0) in participants from Latin America and North Africa. Among post-migration-HIV acquisitions, those within 1 year after migration represented 13.1% overall (95%CI: 11.6-14.6), being highest in participants from sub-Saharan Africa (25%; 95%CI: 21.5-28.3). Participants ≥ 15-years old at migration, with post-migration-acquired HIV, had a 7.5-year median interval from arrival in France to HIV acquisition (interquartile range (IQR): 3.50-14.75). Older age at arrival, region of origin (sub-Saharan Africa and Asia), degree of social disadvantage and numbers of sexual partners were independently associated with acquiring HIV within 1 year in France.ConclusionOur findings may guide HIV prevention policies for most vulnerable migrants to Europe.

RESUMEN

BACKGROUND: A previous study showed an association between CD4 T-cell count decline in people with human immunodeficiency virus infection (PWH) with viral suppression and an increased risk of severe morbid conditions. We aimed to assess the risk of CD4 T-cell count decline (hereafter, CD4 decline), determine associated factors, and evaluate the association of this decline with the risk of severe morbid conditions (cardiovascular disease and cancer) or death. METHODS: From the Agence Nationale de Recherches sur le SIDA et les hépatites virales (ANRS) CO4 French Hospital Database on HIV cohort, we selected PWH >18 years old who had been followed up for ≥2 years after viral suppression following the initiation of combination antiretroviral therapy (cART) between 2006 and 2018. CD4 decline was defined as 2 consecutive relative differences ≥15%. Among participants with such decline, we modeled CD4, CD8, and total lymphocyte counts before and after CD4 decline, using spline regression. The remaining objectives were assessed using Poisson regression, with the association between CD4 decline and the risk of severe morbid conditions or death evaluated during or after 6 months of decline. RESULTS: Among 15 714 participants (75 417 person-years), 181 presented with CD4 decline (incidence rate, 2.4/1000 person-years (95% confidence interval, 2.1-2.8). CD8 and total lymphocyte counts also showed a similar decline. Older current age and lower viral load at treatment initiation were associated with the risk of CD4 decline. The risk of severe morbid conditions or death was 11-fold higher during the first 6 months for participants who presented with CD4 decline versus those who did not (incidence rate ratio, 10.8 [95% confidence interval, 5.1-22.8]), with no significant difference after 6 months. CONCLUSIONS: In PWH with viral suppression, CD4 decline was rare and related to global lymphopenia. It was associated with a higher risk of severe morbid conditions or death during the first 6 months.

RESUMEN

BACKGROUND: Many studies have reported weight gain in ART-naive people living with HIV (PWH) initiating an integrase strand-transfer inhibitor-based regimen. We studied the impact of early or advanced presentation and that of individual drugs in PWH initiating combined ART (cART) between 2012 and 2018. METHODS: From the French Hospital Database HIV cohort, we assessed factors associated with a weight gain  ≥10%, weight change after cART initiation or BMI increase  ≥5 kg/m2 up to 30 months. The analyses were conducted overall, and among PWH with early (primary infection or CD4 >350/mm3 and viral load  <100 000 copies/mL, without AIDS) and advanced presentation (AIDS or CD4 <200/mm3, not during primary infection). RESULTS: At 30 months, 34.5% (95% CI: 33.5-35.6) of the 12 773 PWH had a weight gain ≥10%, with 20.9% (95% CI: 19.6-22.2) among the 5794 with early presentation and 63.1% (95% CI: 60.9-65.3) among the 3106 with advanced presentation. Weight gain was 2.8 kg (95% CI: 2.0-3.7) for those with early presentation and 9.7 kg (95% CI: 8.4-11.1) for those with advanced presentation. Most weight gain occurred in the first 12 months. Underweight and obese PWH were at significantly higher risk of a BMI increase  ≥5 kg/m2 than normal-weight PWH. Results differed within classes and by outcome. Raltegravir and dolutegravir were consistently associated with greater weight gain than the other third agents. Tenofovir alafenamide was also associated with higher weight gain than tenofovir disoproxil or abacavir. CONCLUSIONS: After initiating cART, PWH with early presentation exhibited a small weight gain, whereas it was large among those with advanced presentation. The choice of ART should account for the risk of weight gain, especially for PWH who present with advanced disease and/or are obese.

RESUMEN

Among persons with HIV (PWH), higher alcohol use and having hepatitis C virus (HCV) are separately associated with increased morbidity and mortality. We investigated whether the association between alcohol use and mortality among PWH is modified by HCV. Data were combined from European and North American cohorts of adult PWH who started antiretroviral therapy (ART). Self-reported alcohol use data, collected in diverse ways between cohorts, were converted to grams/day. Eligible PWH started ART during 2001-2017 and were followed from ART initiation for mortality. Interactions between the associations of baseline alcohol use (0, 0.1-20.0, >20.0 g/day) and HCV status were assessed using multivariable Cox models. Of 58,769 PWH, 29,711 (51%), 23,974 (41%) and 5084 (9%) self-reported alcohol use of 0 g/day, 0.1-20.0 g/day, and > 20.0 g/day, respectively, and 4799 (8%) had HCV at baseline. There were 844 deaths in 37,729 person-years and 2755 deaths in 443,121 person-years among those with and without HCV, respectively. Among PWH without HCV, adjusted hazard ratios (aHRs) for mortality were 1.18 (95% CI: 1.08-1.29) for 0.0 g/day and 1.84 (1.62-2.09) for >20.0 g/day compared with 0.1-20.0 g/day. This J-shaped pattern was absent among those with HCV: aHRs were 1.00 (0.86-1.17) for 0.0 g/day and 1.64 (1.33-2.02) for >20.0 g/day compared with 0.1-20.0 g/day (interaction p < .001). Among PWH without HCV, mortality was higher in both non-drinkers and heavy drinkers compared with moderate alcohol drinkers. Among those with HCV, mortality was higher in heavy drinkers but not non-drinkers, potentially due to differing reasons for not drinking (e.g. illness) between those with and without HCV.

RESUMEN

INTRODUCTION: In recent years, HIV testing frequency has increased, resulting in more people being diagnosed during seroconversion with a temporarily low CD4 count. Using the current consensus definition of late HIV presentation ('presenting for care with a CD4 count < 350 cells/µL or an AIDS-defining event, regardless of CD4 count') these individuals would be incorrectly assigned as being diagnosed late. METHODS: In spring 2022, a European expert group convened to revise the current late HIV presentation consensus definition. A survey on data availability to apply this revised definition was sent to nominated European focal points responsible for HIV surveillance (n = 53). RESULTS: Experts agreed that the updated definition should refer to late HIV diagnosis rather than presentation and include the following addition: People with evidence of recent infection should be reclassified as 'not late', with evidence of recent infection considered hierarchically. The individual must have: (i) laboratory evidence of recent infection; (ii) a last negative HIV test within 12 months of diagnosis; or (iii) clinical evidence of acute infection. People with evidence of being previously diagnosed abroad should be excluded. A total of 18 countries responded to the survey; 83% reported capturing CD4 count and/or AIDS at diagnosis through national surveillance, 67% captured last negative test and/or previous HIV diagnosis, 61% captured seroconversion illness at diagnosis and 28% captured incident antibody results. CONCLUSIONS: Accurate data on late diagnosis are important to describe the effects of testing programmes. Reclassification of individuals with recent infection will help to better identify populations most at risk of poor HIV outcomes and areas for intervention.

RESUMEN

OBJECTIVES: Biliary brushings and biopsies obtained during endoscopic retrograde cholangiopancreatography (ERCP) have a low sensitivity for the diagnosis of malignant biliary strictures. While cholangioscopic analysis is useful, visual criteria have not yet been defined. The aim of this study was to identify visual criteria for the diagnosis of indeterminate biliary strictures (IDBS). METHODS: A multicenter study was conducted based on the analysis of cholangioscopic recordings of IBDS. Diagnostic criteria were identified in a study group and verified in a validation group. RESULTS: Four criteria were identified to be associated with malignancy, one negatively ("endobiliary material," odds ratio [OR] 0.62, 95% confidence interval [CI] 0.41-0.92) and three positively ("vascularized villous projections," OR 1.52, 95% CI 1.03-2.24; "twisted or dilated vessels," OR 2.18, 95% CI 1.47-3.24; and "dark color of the mucosa," OR 1.82, 95% CI 1.23-2.70). Between two playbacks, the mean (95% CI) sensitivity of the observer's visual diagnosis increased from 66.1% (60-72) to 73.8% (69-78) (P = 0.004); in the second playback, the kappa value for interobserver agreement ranged between 0.36 (color) and 0.56 (endobiliary material), with a significant improvement (P = 0.0031-0.0001) between the first and second playbacks. Blind assessment by endoscopists not involved in this study had a diagnostic accuracy of 73% (71.4-74.5). CONCLUSION: The four identified cholangioscopic features are easy to implement in clinical practice and have the potential to increase the level of diagnostic confidence during the workup of IDBS.

RESUMEN

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.

RESUMEN

BackgroundDespite the availability of highly effective direct-acting antivirals (DAAs) and the expected treatment as prevention (TasP) effect, transmission of hepatitis C virus (HCV) persists in men who have sex with men (MSM) who engage in high-risk sexual behaviours.AimWe aimed to estimate the incidence of primary HCV infection among MSM living with HIV in France when DAA was readily available.MethodsWe used data from a large French hospital cohort of persons living with HIV (ANRS CO4-FHDH) prospectively collected between 2014 and 2017. HCV incidence rates were calculated using person-time methods for HCV-negative MSM at inclusion who had serological follow-up from 1 January 2014 to 31 December 2017. Sensitivity analyses were performed by varying the main assumptions to assess their impact on the results.ResultsOf 14,273 MSM living with HIV who were initially HCV-seronegative, 330 acquired HCV during follow-up over 45,866 person-years (py), resulting in an overall estimated incidence rate of 0.72/100 py (95% CI: 0.65-0.80). HCV incidence significantly decreased from 0.98/100 py (95% CI: 0.81-1.19) in 2014 to 0.45/100 py (95% CI: 0.35-0.59) in 2017 (54% decrease; 95% CI: 36-67). This trend was confirmed by most of the sensitivity analyses.ConclusionThe primary incidence of HCV was halved for MSM living with HIV between 2014 and 2017. This decrease may be related to unrestricted DAA availability in France for individuals living with HIV. Further interventions, including risk reduction, are needed to reach HCV micro-elimination in MSM living with HIV.

RESUMEN

BACKGROUND: The Data Collection on Adverse Events of Anti-HIV Drugs (DAD) study has reported an increased risk of cardiovascular diseases in people with human immunodeficiency virus who were exposed to darunavir (DRV) but not to atazanavir (ATV). Our objective was to evaluate associations between ATV or DRV exposures and the risk of myocardial infarction (MI) in a nested case-control study within ANRS-CO4 French Hospital Database on HIV (FHDH). METHODS: Cases were individuals who had a first validated MI between 2006 and 2012. Up to 5 controls were selected at random with replacement among individuals with no history of MI, followed at the time of MI diagnosis, and matched for age and sex. Conditional logistic regression models were used to adjust for potential confounders (MI risk factors and HIV-related parameters) and for cumulative exposure to each antiretroviral drug (ARV). RESULTS: Overall, 408 MI cases and 1250 controls were included: 109 (27%) cases and 288 (23%) controls had been exposed to ATV, and 41 (10%) cases and 107 (9%) controls had been exposed to DRV. There was no significant association between exposure to ATV (adjusted odds ratio [OR] = 1.54; 95% confidence interval [CI], .87-2.73) or DRV (adjusted OR = 0.51; 95% CI, .11-2.32) and the risk of MI. CONCLUSIONS: In FHDH, exposures to ATV or to DRV were not significantly associated with the risk of MI, adjusting for complete ARV history, contrary to the analysis in DAD.

RESUMEN

People living with HIV (PLHIV) are more likely than the general population to develop AIDS-defining malignancies (ADMs) and several non-ADMs (NADMs). Information is lacking on survival outcomes and cause-specific mortality after cancer diagnosis among PLHIV. We investigated causes of death within 5 years of cancer diagnosis in PLHIV enrolled in European and North American HIV cohorts starting antiretroviral therapy (ART) 1996-2015, aged ≥16 years, and subsequently diagnosed with cancer. Cancers were grouped: ADMs, viral NADMs and nonviral NADMs. We calculated cause-specific mortality rates (MR) after diagnosis of specific cancers and compared 5-year survival with the UK and France general populations. Among 83,856 PLHIV there were 4,436 cancer diagnoses. Of 603 deaths after ADM diagnosis, 292 (48%) were due to an ADM. There were 467/847 (55%) and 74/189 (39%) deaths that were due to an NADM after nonviral and viral NADM diagnoses, respectively. MR were higher for diagnoses between 1996 and 2005 versus 2006-2015: ADMs 102 (95% CI 92-113) per 1,000 years versus 88 (78-100), viral NADMs 134 (106-169) versus 111 (93-133) and nonviral NADMs 264 (232-300) versus 226 (206-248). Estimated 5-year survival for PLHIV diagnosed with liver (29% [19-39%]), lung (18% [13-23%]) and cervical (75% [63-84%]) cancer was similar to general populations. Survival after Hodgkin's lymphoma diagnosis was lower in PLHIV (75% [67-81%]). Among ART-treated PLHIV diagnosed with cancer, MR and causes of death varied by cancer type, with mortality highest for liver and lung cancers. Deaths within 5 years of NADM diagnoses were more likely to be from cancer than AIDS.

RESUMEN

We compared invasive cervical cancer (ICC) incidence rates in Europe, South Africa, Latin and North America among women living with HIV who initiated antiretroviral therapy (ART) between 1996 and 2014. We analyzed cohort data from the International Epidemiology Databases to Evaluate AIDS (IeDEA) and the Collaboration of Observational HIV Epidemiological Research in Europe (COHERE) in EuroCoord. We used flexible parametric survival models to determine regional ICC rates and risk factors for incident ICC. We included 64,231 women from 45 countries. During 320,141 person-years (pys), 356 incident ICC cases were diagnosed (Europe 164, South Africa 156, North America 19 and Latin America 17). Raw ICC incidence rates per 100,000 pys were 447 in South Africa (95% confidence interval [CI]: 382-523), 136 in Latin America (95% CI: 85-219), 76 in North America (95% CI: 48-119) and 66 in Europe (95% CI: 57-77). Compared to European women ICC rates at 5 years after ART initiation were more than double in Latin America (adjusted hazard ratio [aHR]: 2.43, 95% CI: 1.27-4.68) and 11 times higher in South Africa (aHR: 10.66, 95% CI: 6.73-16.88), but similar in North America (aHR: 0.79, 95% CI: 0.37-1.71). Overall, ICC rates increased with age (>50 years vs. 16-30 years, aHR: 1.57, 95% CI: 1.03-2.40) and lower CD4 cell counts at ART initiation (per 100 cell/µl decrease, aHR: 1.25, 95% CI: 1.15-1.36). Improving access to early ART initiation and effective cervical cancer screening in women living with HIV should be key parts of global efforts to reduce cancer-related health inequities.

RESUMEN

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.

RESUMEN

BACKGROUND: There is no consensus on screening strategy of high-grade intraepithelial neoplasia (HGAIN). Guidelines range from clinical examination with digital anorectal examination followed by standard anoscopy (SA), to anal cytology (Pap)+/- HPV genotyping. We compared screening strategy yields based on Pap, SA, and HPV-16 genotyping alone or in combination in HIV-MSM. METHODS: Pap, SA, and HPV-16 genotyping were performed in all HIV-MSM attending a first anal cancer screening consultation in Paris, France. High-resolution anoscopy, the gold standard to detect HGAIN, was performed in the case of HPV-16 positivity or abnormal cytology. Yield was defined as the number of patients with HGAIN relative to the total number of patients screened. RESULTS: On 212 patients, the complete strategy (SA + Pap + HPV genotyping) yield (12.7%) was significantly higher than that of SA (3.3%, p < 0.001) and HPV-16 alone (6.6%, p < 0.05). Although none of the other strategies were significantly different from the complete strategy, Pap + HPV-16 and Pap + SA had closer yields (about 11%), with OR = 0.83 (95% CI [0.44;1.57]) and 0.87 (95% CI [0.46;1.64]), respectively. CONCLUSIONS: Pap combined with HPV-16 genotyping or SA tended towards higher yields compared to Pap alone, and closer to that of the complete strategy.

RESUMEN

Short and long sleep durations have been associated with inflammation and chronic diseases. To study the association between sleep duration/quality and HIV disease severity, a cross-sectional study was conducted in patients living with HIV (PLWHs) using self-administered questionnaires assessing total sleep time, insomnia (ICSD-3 criteria), and poor sleep quality (PSQI > 5). Multivariable logistic regression identified the factors associated with sleep disorders and with HIV features. 640 Parisian ambulatory PLWHs were included. The prevalence of insomnia was 50 and 68% of patients had a PSQI > 5. Patients with CD4 count < 500 cells/mm3 were more likely to be long sleepers (> 8 h/day) (OR 1.49; 95% CI [1.10-1.99]: p < 0.01), and less likely to be short sleepers (< 6 h/day) (OR 0.69; 95% CI[0.50-0.96]; p = 0.04) or to experience insomnia (OR 0.59; 95% CI[0.40-0.86]; p < 0.01). HIV features were not associated with a PSQI > 5. Thus, insomnia and impaired sleep quality were highly prevalent in well-controlled PLWHs and the severity of HIV infection was associated with long sleep times.

RESUMEN

BACKGROUND: The Marginal Structural Cox Model (Cox-MSM), an alternative approach to handle time-dependent confounder, was introduced for survival analysis and applied to estimate the joint causal effect of two time-dependent nonrandomized treatments on survival among HIV-positive subjects. Nevertheless, Cox-MSM performance in the case of multiple treatments has not been fully explored under different degree of time-dependent confounding for treatments or in case of interaction between treatments. We aimed to evaluate and compare the performance of the marginal structural Cox model (Cox-MSM) to the standard Cox model in estimating the treatment effect in the case of multiple treatments under different scenarios of time-dependent confounding and when an interaction between treatment effects is present. METHODS: We specified a Cox-MSM with two treatments including an interaction term for situations where an adverse event might be caused by two treatments taken simultaneously but not by each treatment taken alone. We simulated longitudinal data with two treatments and a time-dependent confounder affected by one or the two treatments. To fit the Cox-MSM, we used the inverse probability weighting method. We illustrated the method to evaluate the specific effect of protease inhibitors combined (or not) to other antiretroviral medications on the anal cancer risk in HIV-infected individuals, with CD4 cell count as time-dependent confounder. RESULTS: Overall, Cox-MSM performed better than the standard Cox model. Furthermore, we showed that estimates were unbiased when an interaction term was included in the model. CONCLUSION: Cox-MSM may be used for accurately estimating causal individual and joined treatment effects from a combination therapy in presence of time-dependent confounding provided that an interaction term is estimated.

RESUMEN

BACKGROUND: Hospital-based Palliative Care Consultation Teams (PCCTs) have a consulting role to specialist services at their request. Referral of patients is often late. Early palliative care in oncology has shown its effectiveness in improving quality of life, thereby questioning the "on request" model of PCCTs. Whether this evidence changed practice is unknown. This multicentre prospective cohort study aims to describe the activity and integration of PCCTs at the patient level. METHODS: For consecutive patients newly referred to participating PCCTs, the team collected the following data: circumstances of first referral, problems identified, number of interventions, patient's survival after first evaluation and place of death. RESULTS: Seventeen PCCTs based in university hospitals in Paris area, recruited 744 newly referred adult patients, aged 72 ± 15 years, 52% males, and 504(68%) with cancer as primary diagnosis. After 6 months, 548(74%) had died. At first evaluation, 12% patients were outpatients, 88% were inpatients. Symptoms represented the main reasons for referral and problems identified; 79% of patients had altered performance status; 24% encountered the PCCT only once. Median survival (1st-3rd quartile) after first evaluation by the PCCT was 22 (5-82) days for overall patients, and respectively 31 (8-107) days and 9 (3-34) days for cancer versus noncancer patients (p < 0.0001). Place of death was acute care hospital for 51.7% patients, and home or Palliative Care Unit for 35%. Patients referred earlier died more often in PCU. CONCLUSION: The study provides original data showing a still late referral to the PCCTs in France. Cancer patients represent their predominant activity. The integrated palliative care model seems to emerge besides the "on request" model which originally characterised their missions.

RESUMEN

BACKGROUND: The burden of Kaposi sarcoma (KS) in human immunodeficiency virus (HIV)-infected children and adolescents on combination antiretroviral therapy (cART) has not been compared globally. METHODS: We analyzed cohort data from the International Epidemiologic Databases to Evaluate AIDS and the Collaboration of Observational HIV Epidemiological Research in Europe. We included HIV-infected children aged <16 years at cART initiation from 1996 onward. We used Cox models to calculate hazard ratios (HRs), adjusted for region and origin, sex, cART start year, age, and HIV/AIDS stage at cART initiation. RESULTS: We included 24 991 children from eastern Africa, southern Africa, Europe and Asia; 26 developed KS after starting cART. Incidence rates per 100 000 person-years (PYs) were 86 in eastern Africa (95% confidence interval [CI], 55-133), 11 in southern Africa (95% CI, 4-35), and 81 (95% CI, 26-252) in children of sub-Saharan African (SSA) origin in Europe. The KS incidence rates were 0/100 000 PYs in children of non-SSA origin in Europe (95% CI, 0-50) and in Asia (95% CI, 0-27). KS risk was lower in girls than in boys (adjusted HR [aHR], 0.3; 95% CI, .1-.9) and increased with age (10-15 vs 0-4 years; aHR, 3.4; 95% CI, 1.2-10.1) and advanced HIV/AIDS stage (CDC stage C vs A/B; aHR, 2.4; 95% CI, .8-7.3) at cART initiation. CONCLUSIONS: HIV-infected children from SSA but not those from other regions, have a high risk of developing KS after cART initiation. Early cART initiation in these children might reduce KS risk.

RESUMEN

OBJECTIVES: To measure azygos, portal and aortic flow by two-dimensional cine phase-contrast magnetic resonance imaging (2D-cine PC MRI), and to compare the MRI values to hepatic venous pressure gradient (HVPG) measurements, in patients with cirrhosis. METHODS: Sixty-nine patients with cirrhosis were prospectively included. All patients underwent HVPG measurements, upper gastrointestinal endoscopy and 2D-cine PC MRI measurements of azygos, portal and aortic blood flow. Univariate and multivariate regression analyses were used to evaluate the correlation between the blood flow and HVPG. The performance of 2D-cine PC MRI to diagnose severe portal hypertension (HVPG ≥ 16 mmHg) was determined by receiver operating characteristic curve (ROC) analysis, and area under the curves (AUC) were compared. RESULTS: Azygos and aortic flow values were associated with HVPG in univariate linear regression model. Azygos flow (p < 10(-3)), aortic flow (p = 0.001), age (p = 0.001) and presence of varices (p < 10(-3)) were independently associated with HVPG. Azygos flow (AUC = 0.96 (95 % CI [0.91-1.00]) had significantly higher AUC than aortic (AUC = 0.64 (95 % CI [0.51-0.77]) or portal blood flow (AUC = 0.40 (95 % CI [0.25-0.54]). CONCLUSIONS: 2D-cine PC MRI is a promising technique to evaluate significant portal hypertension in patients with cirrhosis. KEY POINTS: • Noninvasive HVPG assessment can be performed with MRI azygos flow. • Azygos MRI flow is an easy-to-measure marker to detect significant portal hypertension. • MRI flow is more specific that varice grade to detect portal hypertension.

RESUMEN

RATIONALE: The occurrence of ventilator-associated pneumonia (VAP) is linked to the aspiration of contaminated pharyngeal secretions around the endotracheal tube. Tubes with cuffs made of polyurethane rather than polyvinyl chloride or with a conical rather than a cylindrical shape increase tracheal sealing. OBJECTIVES: To test whether using polyurethane and/or conical cuffs reduces tracheal colonization and VAP in patients with acute respiratory failure. METHODS: We conducted a multicenter, prospective, open-label, randomized study in four parallel groups in four intensive care units between 2010 and 2012. A cohort of 621 patients with expected ventilation longer than 2 days was included at intubation with a cuff composed of cylindrical polyvinyl chloride (n = 148), cylindrical polyurethane (n = 143), conical polyvinyl chloride (n = 150), or conical polyurethane (n = 162). We used Kaplan-Meier estimates and log-rank tests to compare times to events. MEASUREMENTS AND MAIN RESULTS: After excluding 17 patients who secondarily refused participation or had met an exclusion criterion, 604 were included in the intention-to-treat analysis. Cumulative tracheal colonization greater than 10(3) cfu/ml at Day 2 was as follows (median [interquartile range]): cylindrical polyvinyl chloride, 0.66 (0.58-0.74); cylindrical polyurethane, 0.61 (0.53-0.70); conical polyvinyl chloride, 0.67 (0.60-0.76); and conical polyurethane, 0.62 (0.55-0.70) (P = 0.55). VAP developed in 77 patients (14.4%), and postextubational stridor developed in 28 patients (6.4%) (P = 0.20 and 0.28 between groups, respectively). CONCLUSIONS: Among patients requiring mechanical ventilation, polyurethane and/or conically shaped cuffs were not superior to conventional cuffs in preventing tracheal colonization and VAP. Clinical trial registered with clinicaltrials.gov (NCT01114022).

RESUMEN

BACKGROUND: Recent studies have shown a decrease in the incidence of herpes zoster (HZ) among human immunodeficiency virus (HIV)-infected patients since the combined antiretroviral therapy (cART) era, but more data are needed on a possible increase in the risk early after cART initiation. METHODS: We studied HZ incidence and risk factors among patients followed in the French Hospital Database on HIV (FHDH) between 1992 and 2011. Standardized incidence ratios (SIRs) were used for comparison with the general population between 2005 and 2008. The risk of HZ following cART initiation (0-5 and ≥6 months) was studied with Poisson regression models. RESULTS: A total of 7167 cases of incident HZ were diagnosed among 91 044 individuals (583 125 person-years [PY]). The incidence declined significantly, from 2955 per 100 000 PY in 1992-1996 to 628 per 100 000 PY in 2009-2011. This decline was mainly explained by cART (relative risk [RR], 0.60; 95% confidence interval {CI}, .57-.64). The risk of HZ was associated with low CD4 cell counts, high HIV RNA levels, low CD4/CD8 ratios, and prior AIDS. Compared to the general population, the risk of HZ was higher in HIV-infected patients (overall SIR, 2.7; 95% CI, 2.6-2.9), particularly those aged 15-44 years (SIR, 4-6). In ART-naive patients, a moderate increase in the HZ risk was observed during the first 6 months of cART, with a peak at 3 months (RR, 1.47; 95% CI, 1.26-1.73), a finding that disappeared after adjustment for the current CD4 cell count (RR, 1.03; 95% CI, .81-1.32). CONCLUSIONS: The risk of HZ has declined markedly among HIV-infected patients in the cART era, but remains 3 times higher than in the general population. The risk increases moderately during the first 6 months of cART.
