RESUMO
OBJECTIVES: HIV pre-exposure prophylaxis (PrEP) is effective in preventing HIV, but some seroconversions occur due to poor adherence or PrEP discontinuation. Our objective was to estimate the incidence of PrEP discontinuation and describe the reasons and factors associated with discontinuations. METHODS: A retrospective cohort was conducted in three French hospitals between January 2016 and June 2022. PrEP users who attended at least twice within 6â months during study period were included and followed up until December 2022. The incidence rate of PrEP discontinuation was estimated by censoring lost to follow up individuals. Factors associated with PrEP discontinuations were identified using a multivariate Cox model. RESULTS: A total of 2785 PrEP users were included, with 94% men and 5% transgender people. Median age was 35â years. By December 2022, 653 users had stopped PrEP (24%). The incidence rate was 10.8 PrEP discontinuations for 100 person-years (PY). The main causes of discontinuation were being in a stable relationship (32%), and not judging the treatment useful anymore (12%). Individuals who discontinued PrEP were younger [<29, HRâ=â1.45 (1.17-1.80)], and more likely to be women [HRâ=â2.44 (1.50-3.96)] or sex workers [HRâ=â1.53 (0.96-2.44)]. They were more likely to report PrEP side effects [HRâ=â2.25 (1.83-2.77)] or ≥2 sexually transmitted infections [HRâ=â1.87 (1.53-2.27)] during the last year. CONCLUSION: The incidence of PrEP discontinuations was quite low compared to rates observed in other cohorts. Users who stopped PrEP were sometimes still exposed to HIV, emphasizing the need for targeted interventions to prepare and support PrEP discontinuations and limit seroconversion risk.

BACKGROUND: Real-world evidence is an essential component of evidence-based medicine. The aim of the BICSTaR (BICtegravir Single Tablet Regimen) study is to assess effectiveness and safety of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in antiretroviral treatment-naïve (TN) and treatment-experienced (TE) people with HIV. METHODS: BICSTaR is a prospective, observational cohort study. Participants (≥18 years) are being followed for 24 months. A pooled analysis is presented at 12 months, with the primary endpoint of effectiveness (HIV-1 RNA <50 copies/mL) and secondary endpoints of safety and tolerability (as per protocol). An exploration of patient-reported outcome measures using standardized questionnaires is included. RESULTS: Between June 2018 and May 2021, 1552 people with HIV were enrolled across 12 countries. The analysed population comprised 1509 individuals (279 TN, 1230 TE); most were white (76%), male (84%) and had one or more comorbid conditions (68%). Median age was 47 years. After 12 months of B/F/TAF treatment, HIV-1 RNA was <50 copies/mL in 94% (221/236) of TN participants and 97% (977/1008) of TE participants. Median CD4 cell count increased by 214 cells/µL (p < 0.001) in TN participants and 13 cells/µL (p = 0.014) in TE participants; median CD4/CD8 ratios increased by 0.30 and 0.03, respectively (both p < 0.001). Persistence was high at 12 months (TN, 97%; TE, 95%). No resistance to B/F/TAF emerged. Study drug-related adverse events occurred in 13% of participants through 12 months, leading to B/F/TAF discontinuation in 6%. CONCLUSIONS: The findings of this study provide robust real-world evidence to support the broad use of B/F/TAF in both TN and TE people with HIV.

OBJECTIVES: The impact of the systematic screening of Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) in men having sex with men (MSM) on these pathogens' epidemiology remains unclear. We conducted a modelling study to analyse this impact in French MSM. METHODS: We modelled NG and CT transmission using a site-specific deterministic compartmental model. We calibrated NG and CT prevalence at baseline using results from MSM enrolled in the Dat'AIDS cohort. The baseline scenario was based on 1 million MSM, 40 000 of whom were tested every 90 days and 960 000 every 200 days. Incidence rate ratios (IRRs) at steady state were simulated for NG, CT, NG and/or CT infections, for different combinations of tested sites, testing frequency and numbers of frequently tested patients. RESULTS: The observed prevalence rate was 11.0%, 10.5% and 19.1% for NG, CT and NG and/or CT infections. The baseline incidence rate was estimated at 138.2 per year per 100 individuals (/100PY), 86.8/100PY and 225.0/100PY for NG, CT and NG and/or CT infections. Systematically testing anal, pharyngeal and urethral sites at the same time reduced incidence by 14%, 23% and 18% (IRR: 0.86, 0.77 and 0.82) for NG, CT and NG and/or CT infections. Reducing the screening interval to 60 days in frequently tested patients reduced incidence by 20%, 29% and 24% (IRR: 0.80, 0.71 and 0.76) for NG, CT and NG and/or CT infections. Increasing the number of frequently tested patients to 200 000 reduced incidence by 29%, 40% and 33% (IRR: 0.71, 0.60 and 0.67) for NG, CT and NG and/or CT infections. No realistic scenario could decrease pathogens' incidence by more than 50%. CONCLUSIONS: To curb the epidemic of NG and CT in MSM, it would not only be necessary to drastically increase screening, but also to add other combined interventions.

Many patients affected by COVID-19 suffer from debilitating persistent symptoms whose risk factors remained poorly understood. This prospective study examined the association of depression and anxiety symptoms measured before and at the beginning of the COVID-19 pandemic with the incidence of persistent symptoms. Among 25,114 participants [mean (SD) age, 48.72 years (12.82); 51.1% women] from the SAPRIS and SAPRIS-Sérologie surveys nested in the French CONSTANCES population-based cohort, depression and anxiety symptoms were measured with the Center for Epidemiologic Studies-Depression scale and the 12-item General Health Questionnaire before the pandemic, and with the 9-item Patient Health Questionnaire and the 7-Item Generalized Anxiety Disorder scale at the beginning of the pandemic (i.e., between April 6, 2020 and May 4, 2020). Incident persistent symptoms were self-reported between December 2020 and January 2021. The following variables were also considered: gender, age, educational level, household income, smoking status, BMI, hypertension, diabetes, self-rated health, and SARS-CoV-2 infection according to serology/PCR test results. After a follow-up of seven to ten months, 2329 participants (9.3%) had been infected with SARS-CoV-2 and 4262 (17.0%) reported at least one incident persistent symptom that emerged from March 2020, regardless of SARS-CoV-2 infection. In multi-adjusted logistic regression models, participants in the highest (versus the lowest) quartile of depressive or anxiety symptom levels before or at the beginning of the pandemic were more likely to have at least one incident persistent symptom (versus none) at follow-up [OR (95%CI) ranging from 2.10 (1.89-2.32) to 3.01 (2.68-3.37)], with dose-response relationships (p for linear trend <0.001). Overall, these associations were significantly stronger in non-infected versus infected participants, except for depressive symptoms at the beginning of the pandemic. Depressive symptoms at the beginning of the pandemic were the strongest predictor of incident persistent symptoms in both infected and non-infected participants [OR (95%CI): 2.88 (2.01-4.14) and 3.03 (2.69-3.42), respectively]. In exploratory analyses, similar associations were found for each symptom taken separately in different models. Depression and anxiety symptoms should be tested as a potential target for preventive interventions against persistent symptoms after an infection with SARS-CoV-2.

Implant-related infections may need suppressive antibiotic therapy (SAT). We describe a SAT strategy using dalbavancin with therapeutic drug monitoring (TDM). This is a retrospective bicentric study of patients with implant-related infection who received dalbavancin SAT between January 2021 and September 2023. Fifteen patients were included. Median number of injections was 4 (IQR: 2-7). Median time between two reinjections was 57 days (IQR 28-82). Dalbavancin plasma concentrations were above 4 mg/L for 97.9% of dosages (93/95) and above 8 mg/L for 85% (81/95). These results support the use of dalbavancin SAT for implant-related infections.

PURPOSE: We aimed to assess risk factors of candida-related Vascular Graft Infections (VGIs). METHODS: We did a case-control study (1:4) matched by age and year of infection, nested in a cohort of patient with a history of VGIs. Cases were defined by a positive culture for Candida spp. in biological samples and controls were defined by a positive culture for bacterial strains only in biological samples. Risk factors for Candida-related VGIs were investigated using multivariate logistic regression. Mortality were compared using survival analysis. RESULTS: 16 Candida-related VGIs were matched to 64 bacterial-related VGIs. The two groups were comparable regarding medical history and clinical presentation. Candida-related VGIs were associated with bacterial strains in 88% (14/16). Gas/fluid-containing collection on abdominal CT scan and the presence of an aortic endoprosthesis were risk factors for Candida spp.-related VGIs [RRa 10.43 [1.81-60.21] p = 0.009 RRa and 6.46 [1.17-35.73] p = 0.03, respectively]. Candida-related VGIs were associated with a higher mortality when compared to bacterial-related VGIs (p = 0.002). CONCLUSIONS: Candida-related VGIs are severe. Early markers of Candida spp. infection are needed to improve their outcome. The suspicion of aortic endoprosthesis infection may necessitate probabilistic treatment with antifungal agents.

COVID-19 pandemic can affect people using HIV preexposure prophylaxis (PrEP). To assess its consequences on PrEP users' sexual behaviour and welfare, we conducted a mixed-method study. A self-administered questionnaire was given to PrEP users during scheduled consultation in Tourcoing Hospital from February to May 2021. In addition, a qualitative study included 14 participants who took part in semi-structured in-depth interviews (IDIs). Ninety-four PrEP users completed the questionnaire. During lockdown, 62% of participants continued PrEP. After lockdown release, the average number of sexual intercourses and partners increased from 6 ± 12 to 13 ± 17 intercourses/month (p < 0.001) and from 3 ± 11 to 11 ± 34 partners/month (p < 0.001). Similarly, the proportion of PrEP users who engaged in group sex, sex with alcohol or chemsex increased respectively from 28% to 55% (p < 0.001), 28% to 45% (p < 0.001) and 28% to 38% (p < 0.001). Analysis of IDIs revealed emotional deprivation and sexual frustration during the lockdown. After its release, frequent clandestine chemsex parties and curfew forcing overnight stay increased fears of intimate violence and overdoses. In conclusion, PrEP users reduced their sexual activity during the lockdown. Its release led to an increase in sexual risk-taking. Social distancing measures could favour medical and social harm of sexual risk-taking.

BACKGROUND: Group B streptococci (Streptococcus agalactiae) (GBS) is a rare cause of prosthetic joint infection (PJI) occurring in patients with comorbidities and seems to be associated with a poor outcome. Depiction of GBS PJI is scarce in the literature. METHODS: A retrospective survey in 2 referral centers for bone joint infections was done Patients with a history of PJI associated with GBS between 2014 and 2019 were included. A descriptive analysis of treatment failure was done. Risk factors of treatment failure were assessed. RESULTS: We included 61 patients. Among them, 41 had monomicrobial (67%) infections. The median duration of follow-up was 2 years (interquartile range 2.35) Hypertension, obesity, and diabetes mellitus were the most reported comorbidities (49%, 50%, and 36% respectively). Death was observed in 6 individuals (10%) during the initial management. The rate of success was 63% (26/41). Removal of the material was not associated with remission (p = 0.5). We did not find a specific antibiotic regimen associated with a better outcome. CONCLUSION: The results show that S. agalactiae PJIs are associated with high rates of comorbidities and a high treatment failure rate with no optimal treatment so far.

INTRODUCTION: Polypharmacy can lead to drug-drug interactions (DDIs), especially with ART. The burden of co-medications, including over-the-counter (OTC) drugs and self-medications, could be underestimated. We aimed to investigate the proportion of people living with HIV (PLHIV) with declared and undeclared co-medications, as well as their potential burden. METHODS: We conducted a national, multicentre, 1 week cross-sectional study between 10 December and 16 December 2019 in 23 French hospitals amongst consecutive adult PLHIV presenting for a routine outpatient visit. A standardized questionnaire filled in by the physicians assessed all medications and other active chemical substances taken by the PLHIV. RESULTS: Overall we enrolled 496 participants from 23 centres. Median age was 50.6 years; ART regimens included an integrase inhibitor in 61% (nâ=â302), an NNRTI in 34% (nâ=â169) and a PI in 14% (nâ=â70) of the cases. Co-medications involved 392 (79%) PLHIV, among which 85 (17%) received polypharmacy (≥5 medications). Previously unknown co-medications or other active substances were found for 32% (nâ=â159) of the participants. Corticosteroids (9%, nâ=â46) and proton pump inhibitors (10%, nâ=â50) were frequently administered. These co-medications did not differ according to age range. Illegal drug use was declared by 11% (nâ=â54) and OTC drugs by 23% (nâ=â113) of PLHIV. Potential DDIs were discovered for 11% (nâ=â53), leading to treatment modifications in 47% (25/53) of cases. CONCLUSIONS: Potential DDIs that lead to therapeutic modifications remain significant whatever the age of PLHIV. More devoted time to identify co-medications and OTC treatment is needed in all PLHIV.

The ongoing outbreak of monkeypox virus (MPXV) is the largest one in historically non-endemic countries. Early reports described atypical epidemiological and clinical presentations. We investigated MPXV DNA detection in oropharyngeal samples (OPS), and compared the viral load to that in lesion samples at diagnosis in patients infected with MPXV. We retrospectively included patients suspected to have monkeypox in Northern France, who underwent a MPXV PCR in the Virology Laboratory, University Hospital of Lille, from May 23 to August 18, 2022. Overall, a total of 228 patients (376 samples) were included. A positive result in at least one sample was found in 138 patients (60.5%). We compared PCR results between OPS and lesion samples (i.e., cutaneous or anal/rectal samples) in patients with both samples. A positive result in OPS was observed in 54 out of 60 patients (90%). The viral load in OPS (median Ct value = 29.5; interquartile range [IQR] = 24.7-34) was significantly lower than that in lesion samples (median Ct value = 17.8; IQR = 16.3 and 19.7) (p < 0.0001). This report shows that pharyngeal sampling does not bring additional information for the initial diagnosis in patients presenting with typical lesions.

BACKGROUND: Taste or smell disorders have been reported as strongly associated with COVID-19 diagnosis. We aimed to identify subject characteristics, symptom associations, and antibody response intensity associated with taste or smell disorders. METHODS: We used data from SAPRIS, a study based on a consortium of five prospective cohorts gathering 279,478 participants in the French general population. In the analysis, we selected participants who were presumably infected by SARS-CoV-2 during the first epidemic wave. RESULTS: The analysis included 3,439 patients with a positive ELISA-Spike. Sex (OR = 1.28 [95% CI 1.05-1.58] for women), smoking (OR = 1.54 [95% CI 1.13-2.07]), consumption of more than 2 drinks of alcohol a day (OR = 1.37 [95% CI 1.06-1.76]) were associated with a higher probability of taste or smell disorders. The relationship between age and taste or smell disorders was non-linear. Serological titers were associated with taste or smell disorders: OR = 1.31 [95% CI 1.26-1.36], OR = 1.37 [95% CI 1.33-1.42] and OR = 1.34 [95% CI 1.29-1.39] for ELISA-Spike, ELISA-Nucleocapsid and seroneutralization, respectively. Among participants with taste or smell disorders, 90% reported a wide variety of other symptoms whereas 10% reported no other symptom or only rhinorrhea. CONCLUSIONS: Among patients with a positive ELISA-Spike test, women, smokers and people drinking more than 2 drinks a day were more likely to develop taste or smell disorders. This symptom was strongly associated with an antibody response. The overwhelming majority of patients with taste or smell disorders experienced a wide variety of symptoms.

BACKGROUND: Staphylococci account for approximately 60% of periprosthetic joint infections (PJIs). Rifampicin (RMP) combination therapy is generally considered to be the treatment of choice for staphylococcal PJIs but carries an important risk of adverse events and drug-drug interactions. Rifabutin (RFB) shares many of the properties of rifampicin but causes fewer adverse events. OBJECTIVES: To compare the minimal inhibitory concentration (MIC), the minimum bactericidal concentrations (MBC), and the minimum biofilm eradication concentrations (MBEC) of rifabutin and rifampicin for staphylococcal clinical strains isolated from PJIs. METHODS: 132 clinical strains of rifampicin-susceptible staphylococci [51 Staphylococcus aureus (SA), 48 Staphylococcus epidermidis (SE) and 33 other coagulase-negative staphylococci (CoNS)] were studied. The MBC and the MBEC were determined using the MBEC® Assay for rifabutin and rifampicin and were compared. RESULTS: When compared with the rifampicin MIC median value, the rifabutin MIC median value was significantly higher for SA (P < 0.05), but there was no statistically significant difference for SE (P = 0.25) and CoNS (P = 0.29). The rifabutin MBC median value was significantly higher than that of rifampicin for SA (P = 0.003) and was lower for SE (P = 0.003) and CoNS (P = 0.03). Rifabutin MBEC median value was statistically lower than that of rifampicin for all strains tested. CONCLUSIONS: Using the determination of MBEC values, our study suggests that rifabutin is more effective than rifampicin against clinical strains of Staphylococcus spp. obtained from PJIs. Using MBECs instead of MICs seems to be of interest when considering biofilms. In vivo higher efficacy of rifabutin when compared with rifampicin needs to be confirmed.

AIMS: Conservative surgery (CS) for diabetic foot osteomyelitis (DFO) consists in removing all or part of the infected bone tissues without amputation, in complement with antibiotic therapy. Data on CS for DFO therapy are scarce. MATERIAL AND METHODS: We performed a retrospective analysis of all DFO episodes treated with CS between 06/2007 and 12/2017. Remission was defined by the absence of soft-tissue infection, complete sustained (i.e. > 1 month) healing of the foot ulcer, favourable (i.e., stabilisation or improvement) radiological outcome, and no need for additional surgery during a 1-year follow-up. RESULTS: During the study period, 47 episodes (in 41 patients) were analysed. Excluding deaths (all unrelated to the DFO; n = 3) or loss to follow-up before 1 year (n = 5), the remission rate was 64.2%. Most failures occurred during the first 6 months (79%, 11/14). Patients who experienced failure had a higher rate of peripheral arterial disease with arterial stenosis than patients in remission (57% vs. 24%, P = 0.03), a higher C-reactive protein rate at admission (116 ± 112 mg/L vs. 48 ± 46 mg/L, P = 0.02), and a trend for a higher rate of abscesses (29% vs. 4%, P = 0.06). At 1-year follow-up, foot ulcers related to transfer lesion were identified in 25.5% of the cases. At the last follow-up (mean 3 ± 2 years), the remission rate was 23/25 (92%). CONCLUSIONS: Our results suggest that CS is a therapeutic option in patients with localised but severe DFO. Clinicians should, however, consider the necessity of revascularisation, and higher risk of failure if surgery is performed in patients presenting with acute foot infections.

BACKGROUND: The optimal length of the intravenous antibiotic treatment of periprosthetic joint infections (PJIs) generally ranges from one to six weeks and is a matter of debate. Most antibiotics active against Gram-positive cocci (GPC) exhibit both high oral bioavailability and bone diffusion. Thus, early oral therapy may be a reasonable option in GPC-related PJIs. METHODS: A 2 year before and after monocentric study that aimed to compare two antibiotic strategies. Empirical intravenous postoperative antibiotic treatment was followed by 7 to 10 days of intravenous targeted therapy ('before' group) or by full orally targeted antibiotic treatment ('after' group). The primary outcome was a treatment failure during follow-up. RESULTS: A total of 93 patients were analysed, 43 and 50 in the before and the after groups, respectively. Both groups were comparable in terms of surgical procedures, comorbidities, microbiological documentation and infection site. Antibiotics prescribed to our patients had high oral bioavailability and bone diffusion with rifampicin/fluoroquinolone combinations being the most frequent antibiotic regimens. Both hospital stay and intravenous antibiotic treatment mean durations were shorter in the before group than in the after group [15.0 versus 11.0 days; (Pâ<â0.01) and 13.0 versus 7.0 days; Pâ<â0.001, respectively]. The remission rate assessed after at least a year of follow-up was comparable in the before and the after groups (hazard ratioâ=â0.70; 95% CI 0.30-1.58). CONCLUSIONS: Full oral targeted antibiotic therapy using a drug regimen with high oral bioavailability and good bone diffusion is an option for the treatment of patients with GPC-related PJIs.

BACKGROUND: Maintenance ART with dolutegravir-based dual regimens have proved their efficacy among HIV-1-infected subjects in randomized trials. However, real-life data are scarce, with limited populations and follow-up. OBJECTIVES: We assessed virological failure (VF) and resistance-associated mutations (RAMs) on dolutegravir maintenance regimens in combination with rilpivirine or with lamivudine or emtricitabine (xTC) and analysed the factors associated with VF. METHODS: Between 2014 and 2018, all HIV-1-infected adults included in the Dat'AIDS cohort and starting dolutegravir/rilpivirine or dolutegravir/xTC as a maintenance dolutegravir-based dual regimen were selected. VF was defined as two consecutive HIV RNA values >50 copies/mL or a single value >400 copies/mL. We compared cumulative genotypes before initiation of a maintenance dolutegravir-based dual regimen with genotype at VF. RESULTS: We analysed 1374 subjects (799 on dolutegravir/rilpivirine and 575 on dolutegravir/xTC) with a median follow-up of 20 months (IQR = 11-31) and 19 months (IQR = 11-31), respectively. VF occurred in 3.8% (n = 30) of dolutegravir/rilpivirine subjects and 2.6% (n = 15) of dolutegravir/xTC subjects. Among subjects receiving dolutegravir/rilpivirine, two genotypes harboured emerging RAMs at VF: E138K on NNRTI (n = 1); and E138K+K101E on NNRTI and N155H on INSTI (n = 1). Among subjects receiving dolutegravir/xTC, no new RAM was detected. The only predictive factor of VF on dolutegravir/rilpivirine was the history of failure on an NNRTI-based regimen (adjusted HR = 2.97, 95% CI = 1.28-6.93). No factor was associated with VF on dolutegravir/xTC. CONCLUSIONS: In this large real-life cohort, dolutegravir/rilpivirine and dolutegravir/xTC sustained virological suppression and were associated with a low rate of VF and RAM emergence. Careful virological screening is essential before switching to dolutegravir/rilpivirine in virologically suppressed patients with a history of NNRTI therapy.

BACKGROUND AND OBJECTIVES: HIV-1 drug resistance testing can be performed in proviral DNA. The non-homogenous distribution of viral variants in cells can impact the performance of this method. We assessed the variability of HIV-1 DNA genotyping results in the same blood sample using a next-generation sequencing (NGS) method. METHODS: For each included patient, a blood sample from a single venipuncture was split into five 1 mL aliquots, which were independently tested in the same run. HIV-1 DNA was quantified in blood samples using real-time PCR, and NGS was performed with the Sentosa platform combined with the Sentosa SQ HIV genotyping Assay. RESULTS: A total of 60 aliquots from 12 samples (12 patients) were tested. The median age was 45.50 years old, and all patients were treated with antiretrovirals. A significant variability can sometimes be observed in HIV-1 DNA quantification between aliquots from the same sample, with a coefficient of variation ranging from 23% to 89%. The analysis of resistance-associated mutations (RAMs) with a 20% cut-off found some discordances in RAMs profile between aliquots from the same sample for 5, 3 and 3 patients in the reverse transcriptase, protease and integrase genes, respectively. The analysis with a lower cut-off (10%) showed additional mutations, but did not improve the intra-sample concordance. CONCLUSIONS: There is an intra-sample variability in HIV-1 DNA resistance test results, and repetition may sometimes bring additional information, but the extent of its clinical impact still requires further investigation.

The process of human immunodeficiency virus (HIV) diagnosis disclosure for vertically infected young people living with HIV has proven decisive for acceptance/adherence to treatment. Herein, we present a cross-sectional study aiming at evaluating how individual and network related variables are associated with reactions to HIV disclosure among them. We used the egocentric approach with a structured questionnaire applied to individuals aged 15-25 years in an HIV referral center in Rio de Janeiro, Brazil. Outcome variable referred to adoption or not of risk behavior after diagnostic disclosure, was classified as "good"/"bad" reactions. Results showed that, of the 80 study participants, 25% reported a "bad reaction" to diagnostic disclosure, an outcome that was more common for patients with at least one friend in their social support network (OR 4.81; 95%CI [1.05-22.07]). In conclusion, a "bad reaction" to HIV serological disclosure may be associated with inadequate structure of the individual's social support network.
RESUMEN: El proceso de divulgación del diagnóstico del virus de inmunodeficiencia humana (VIH) es decisivo para la aceptación/adhesión a tratamiento de los jóvenes infectados verticalmente que viven con VIH. Presentamos un estudio transversal con el objetivo de evaluar cómo variables individuales y de red están asociadas con reacciones a la divulgación del VIH entre ellos. Utilizamos el enfoque egocéntrico por medio de un cuestionario estructurado aplicado a personas de 15-25 años en un Centro de Referencia para VIH en Río de Janeiro, Brasil. La variable de resultado se refiere a la adopción o no de comportamiento de riesgo después de la divulgación del diagnóstico, clasificadas como reacciones "buena"/"mala". Los resultados mostraron que, de los 80 participantes del estudio, el 25% reportó una "mala reacción" a la divulgación diagnóstica. Este resultado fue más común en pacientes con al menos un amigo en su red de apoyo social (OR:4.81; IC95% [1.05-22.07]). Como conclusión, una "mala reacción" a la divulgación serológica del VIH puede estar asociada con una estructura inadecuada de la red de apoyo social del individuo.

BACKGROUND: We assessed prevalence of multimorbidity (MM) according to year of human immunodeficiency virus (HIV) diagnosis in elderly people living with HIV (PLWH). METHODS: This was a cross-sectional study of MM in PLWH aged ≥70 years from the Dat'AIDS French multicenter cohort. MM was defined as at least 3 coexistent morbidities of high blood pressure, diabetes mellitus, osteoporosis, non-AIDS cancer, chronic renal failure, cardiovascular and cerebrovascular disease, obesity, undernutrition, or hypercholesterolemia. Logistic regression models evaluated the association between MM and calendar periods of HIV diagnosis (1983-1996, 1997-2006, and 2007-2018). The secondary analysis evaluated MM as a continuous outcome, and a sensitivity analysis excluded PLWH with nadir CD4 count <200 cells/µL. RESULTS: Between January 2017 and September 2018, 2476 PLWH were included. Median age was 73 years, 75% were men, median CD4 count was 578 cells/µL, and 94% had controlled viremia. MM prevalence was 71%. HBP and hypercholesterolemia were the most prevalent comorbidities. After adjustment for age, gender, smoking status, hepatitis C and hepatitis B virus coinfection, group of exposure, nadir CD4 count, CD4:CD8 ratio, and last CD4 level, calendar period of diagnosis was not associated with MM (Pâ =â .169). MM was associated with older age, CD4/CD8 ratio <0.8, and nadir CD4 count <200 cells/µL. Similar results were found with secondary and sensitivity analyses. CONCLUSIONS: MM prevalence was high and increased with age, low CD4/CD8 ratio, and nadir CD4 count <200 cells/µL but was not associated with calendar periods of HIV diagnosis. Known duration of HIV diagnosis does not seem to be a criterion for selecting elderly PLWH at risk of MM.

BACKGROUND: Integrase strand transfer inhibitors (INSTIs) are increasingly used in patients living with HIV due to their safety, effectiveness and high genetic barrier. However, an association with weight gain has recently been suggested and several cases of diabetes mellitus have been reported with raltegravir and dolutegravir. The long-time metabolic impact of these recent molecules remains unclear. OBJECTIVES: To assess if an INSTI as a third agent is statistically associated with new-onset diabetes mellitus compared with an NNRTI or a PI. PATIENTS AND METHODS: Patients undergoing first-line combined ART (cART) without diabetes at baseline were retrospectively included from the Dat'AIDS French cohort study (ClinicalTrials.gov NCT02898987). Incident diabetes mellitus was defined as a notification of new diabetes in the medical history, a glycated haemoglobin (HbA1c) level superior to 7.5% or the start of a diabetes therapy following the initiation of ART. RESULTS: From 2009 to 2017, 19 462 patients were included, among which 265 cases of diabetes mellitus occurred. Multivariate and survival analyses did not highlight an increase in new-onset diabetes in patients undergoing cART with an INSTI as a third agent compared with an NNRTI or a PI. BMI >30 kg/m2, age >37 years old (in survival analysis), black race or Hispanic ethnicity, arterial hypertension and AIDS were associated with a higher proportion of incident diabetes. CONCLUSIONS: INSTIs were not statistically associated with new-onset diabetes. However, clinicians should remain aware of this possible metabolic comorbidity, particularly in patients with a high BMI and older patients.

For people living with HIV, determinants of immunological non-response (INR) to combined antiretroviral therapy (cART) have not been fully elucidated. In a case-control study, we evaluated the influence of the nutritional and antioxidant status in HIV-1 adults whose cART was initiated between January 2001 and December 2013. Cases had persistent CD4 counts < 350/µL vs. > 350/µL for controls, after at least 2 years of cART with persistent viral loads (VL) < 50 copies/mL. Twelve cases and twenty-eight control subjects with the same CD4 count at cART initiation were compared for their nutritional and antioxidant status after age adjustment at dosage assessment. Patients were predominantly male (70%), Caucasian (82%) and at AIDS stage (62%). The median age was 53, and the median CD4 count was 245/mm3 for cases and 630/mm3 for controls after a median time of 7 years on cART. Despite higher energy intakes in cases, anthropometric data was comparable between groups who had similar vitamins B9/B12/C/D/E, zinc, citrulline and glutamine levels. Nine cases (75%) and 8 controls (29%) had hypervitaminosis A (> 2.70 µmol/L) (p = 0.030). Cases had lower erythrocyte resistance when exposed to a controlled free radical attack (p = 0.014). Most cases had hypervitaminosis A and altered antioxidant capacities that could affect immunological response. Wide-scale studies are required, but in the meantime, screening of their vitamin A status must be encouraged in these patients.
