AIM: Metabolic risk factors are poorly documented for the first generation of young adults who have lived with HIV since childhood. We compared their metabolic profile with that of adults of same age from the general population. METHODS: We conducted a cross-sectional analysis of data from two populations: (1) COVERTE (ANRS-CO19), a French national cohort of 18 to 30-year-old patients HIV-infected since childhood, and (2) ENNS, a national cross-sectional population-based household survey on nutrition. Body mass index (BMI), blood pressure, waist circumference, fasting glucose, triglycerides, and HDL-, LDL- and total cholesterol were measured in both studies. Direct standardization on overweight and education level and logistic regression were used to compare the prevalence of metabolic abnormalities between the two populations. RESULTS: Data from 268 patients from COVERTE and 245 subjects from ENNS were analyzed. Tobacco use was similar in both groups. HIV-infected patients had increased mean waist-to-hip ratio and triglycerides to HDL-cholesterol ratio and decreased mean HDL-cholesterol as compared to their counterparts from the general population in both genders. In HIV-infected patients, metabolic syndrome was identified in 13.2% of men (95% confidence interval [CI]: 7.1-19.2) and 10.4% (95% CI: 5.4-15.3) of women versus 10.6% (95%CI: 1.5-19.7) and 1.7% (95%CI: 0-4.1) in subjects from the general population, respectively. CONCLUSION: Young adults infected with HIV since childhood had a higher prevalence of dyslipidemia and metabolically detrimental fat distribution than adults of same age of the general population, supporting close monitoring for cardiometabolic diseases

Meat consumption and mortality -results from the European Prospective Investigation into Cancer and Nutrition

Abstract Background: Recently, some US cohorts have shown a moderate association between red and processed meat consumption and mortality supporting the results of previous studies among vegetarians. The aim of this study was to examine the association of red meat, processed meat, and poultry consumption with the risk of early death in the European Prospective Investigation into Cancer and Nutrition (EPIC). Methods: Included in the analysis were 448,568 men and women without prevalent cancer, stroke, or myocardial infarction, and with complete information on diet, smoking, physical activity and body mass index, who were between 35 and 69 years old at baseline. Cox proportional hazards regression was used to examine the association of meat consumption with all-cause and cause-specific mortality. Results: As of June 2009, 26,344 deaths were observed. After multivariate adjustment, a high consumption of red meat was related to higher all-cause mortality (hazard ratio (HR) = 1.14, 95% confidence interval (CI) 1.01 to 1.28, 160+ versus 10 to 19.9 g/day), and the association was stronger for processed meat (HR = 1.44, 95% CI 1.24 to 1.66, 160+ versus 10 to 19.9 g/day). After correction for measurement error, higher all-cause mortality remained significant only for processed meat (HR = 1.18, 95% CI 1.11 to 1.25, per 50 g/d). We estimated that 3.3% (95% CI 1.5% to 5.0%) of deaths could be prevented if all participants had a processed meat consumption of less than 20 g/day. Significant associations with processed meat intake were observed for cardiovascular diseases, cancer, and 'other causes of death'. The consumption of poultry was not related to all-cause mortality. Conclusions: The results of our analysis support a moderate positive association between processed meat consumption and mortality, in particular due to cardiovascular diseases, but also to cancer

HIV-mediated immune aging in young adults infected perinatally or during childhood

International audienceBACKGROUND: HIV-infected patients progressing towards disease present a premature immune aging profile, characterized by the exhaustion of lymphopoiesis. The development of these anomalies may be prevented in young HIV-infected patients owing to their robust immune resources and lymphocyte regeneration capacities.METHODS: An immunomonitoring substudy was designed for young adults aged between 18 and 25 years, living with HIV since childhood included in the national ANRS Co19 COVERTE Cohort. We compared markers associated with immune aging, including the frequency of circulating hematopoietic progenitors and the phenotype of lymphocyte populations, with those of patients infected with HIV in adulthood.RESULTS: HIV-infected young adults displayed decreasing numbers of CD34 hematopoietic progenitors and mature lymphocytes, indicative of general lymphopenia and reminiscent of the alterations found in patients infected in adulthood or uninfected elderly people. This highlights the strong impact of HIV on the immune system despite patient's young age at infection. Immune aging-related alterations were particularly obvious in young patients who presented high viral loads.CONCLUSION: HIV-infected young adults can present increased markers of immune activation and senescence, related to uncontrolled viral replication. This highlights the issue of noncompliance to antiretroviral therapy in patients at a young age, resulting in loss of viral control, premature immunosenescence, and potentially irreversible damage of their lymphopoietic system

Brief Report: frailty in aging people living with HIV: a matched controlled study

International audienceBackground: We compared the prevalence of frailty among aging people living with HIV (PLHIV) with people without HIV from the ANS EP58 HAND 55–70 Study.Methods: Cross-sectional multicentric study which consecutively included 200 PLHIV and 1000 people without HIV from the French national CONSTANCES cohort, matched on age, sex, and education level. PLHIV were aged 55–70 years, with a HIV viral load 200 cells/µL for the last 24 and 12 months, respectively. We measured frailty (>2 items) and prefrailty (one or 2 items) using a proxy of the 5-item Fried score. Multivariate logistic regression was performed to assess the association between HIV and frailty/prefrailty, adjusting for demographic, social, behavioral, and comorbidity confounders.Results: Outcome measures were available for 192 PLHIV and 822 people without HIV. The median age was 62 years, and 84.9% were men. Among PLHIV, the median CD4 cell count was 645.5 cells/µL. Prevalence of frailty/prefrailty was 5.73%/57.3% in PLHIV vs. 1.73%/52.2% in people without HIV, respectively. HIV was associated with prefrailty/frailty [odds ratio = 1.89; 95% confidence interval = 1.37 to 2.61), but after adjusting for social and behavioral factors and comorbidities, HIV was not significantly associated with prefrailty/frailty (odds ratio = 1.24; 95% confidence interval: = 0.84 to 1.81). In PLHIV only, frailty/prefrailty was associated with depressive symptomatology, kidney disease, and time since HIV infection.Conclusions: Prevalence of frailty is increased in aging PLHIV with well-controlled HIV disease, but other factors than HIV are predominant, particularly depression and comorbidities

Sotrovimab to Prevent Severe COVID-19 in High-Risk Patients Infected with Omicron BA.2

International audienceBefore the Omicron era, the neutralizing antibody targeting the SARS-CoV2 Spike protein Sotrovimab has been shown to reduce the risk of COVID-19-related hospitalization in patients who are at high risk for progression (1, 2). We recently showed that early administration of Sotrovimab in Omicron-infected patients with very high-risk for progression was associated with a low rate of COVID-19-related hospitalization within one month after treatment administration (3%), and with no death (1). However, the dominance of the Omicron sublineage BA.2 led health agencies to suspend Sotrovimab emergency use authorizations because of its lower neutralizing ability in vitro compared to BA.1 sublineage (3, 4). Clinical efficiency of Sotrovimab to prevent COVID-19 related complications in high-risk patients with mild-to-moderate COVID-19 Omicron BA.2 remains unknown. Our aim was to compare the clinical and virological outcomes of Omicron BA.1 and BA.2-infected patients with mild-to-moderate COVID-19 who received 500 mg of Sotrovimab IV to prevent COVID-19-related complications

Time to negative PCR conversion amongst high-risk patients with mild-to-moderate Omicron BA.1 and BA.2 COVID-19 treated with sotrovimab or nirmatrelvir

International audienceObjectives: Our aim was to compare the clinical and virological outcomes of Omicron BA.1 and BA.2-infected patients who received Sotrovimab or Nirmatrelvir to prevent severe COVID-19.Methods: In the multicentric prospective ANRS 0003S CoCoPrev cohort study, patients at high-risk for progression with mild-to-moderate BA.1 or BA.2 COVID-19 who received Sotrovimab or Nirmatrelvir were included. Proportion of patients with progression to severe COVID-19, time between the start of treatment to negative PCR, SARS-CoV-2 viral decay, and characterization of resistance variants were determined. A multivariable Cox proportional hazard model was used for time to negative PCR and a mixed effect model for the dynamics of viral decay.Results: Among the 255 included patients, of whom 199/255 (80%) received ≥3 vaccine doses, 195/255 (76%) received Sotrovimab and 60/255 (24%) received Nirmatrelvir. At day 28, new COVID-19-related hospitalization occurred in 4/193 (2%, 95%CI 1-5%) Sotrovimab-treated patients, and 0/55 Nirmatrelvir-treated patient (p=0.24). One out of 55 Nirmatrelvir-treated patients died (2%, 95%CI 0-10%). The median time to negative PCR was 11.5 days (95%CI 10.5-13) in Sotrovimab-treated patients vs. 4 days (95% CI 4-9) in Nirmatrelvir-treated patients (p<0.001). Viral decay was faster in patients who received Nirmatrelvir (p<0.001). In multivariable analysis Nirmatrelvir and nasopharyngeal PCR cycle threshold value were independently associated with a faster conversion to negative PCR (HR 2.35, 95%CI 1.56-3.56, p<0.0001, and HR 1.05, 95%CI 1.01-1.08, p=0.01, respectively).Conclusions: Early administration of Nirmatrelvir in high-risk patients, compared to Sotrovimab, was associated with a faster viral clearance. This may participate to decrease transmission and prevent viral resistance

Challenges in estimating the validity of dietary acrylamide measurements

Acrylamide is a chemical compound present in tobacco smoke and food, classified as a probable human carcinogen and a known human neurotoxin. Acrylamide is formed in foods, typically carbohydrate-rich and protein-poor plant foods, during high-temperature cooking or other thermal processing. The objectives of this study were to compare dietary estimates of acrylamide from questionnaires (DQ) and 24-h recalls (R) with levels of acrylamide adduct (AA) in haemoglobin. In the European Prospective Investigation into Cancer and Nutrition (EPIC) study, acrylamide exposure was assessed in 510 participants from 9 European countries, randomly selected and stratified by age, sex, with equal numbers of never and current smokers. After adjusting for country, alcohol intake, smoking status, number of cigarettes and energy intake, correlation coefficients between various acrylamide measurements were computed, both at the individual and at the aggregate (centre) level. Individual level correlation coefficient between DQ and R measurements (r (DQ,R)) was 0.17, while r (DQ,AA) and r (R,AA) were 0.08 and 0.06, respectively. In never smokers, r (DQ,R), r (DQ,AA) and r (R,AA) were 0.19, 0.09 and 0.02, respectively. The correlation coefficients between means of DQ, R and AA measurements at the centre level were larger (r &gt; 0.4). These findings suggest that estimates of total acrylamide intake based on self-reported diet correlate weakly with biomarker AA Hb levels. Possible explanations are the lack of AA levels to capture dietary acrylamide due to individual differences in the absorption and metabolism of acrylamide, and/or measurement errors in acrylamide from self-reported dietary assessments, thus limiting the possibility to validate acrylamide DQ measurements
