RESUMEN

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.

RESUMEN

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.

RESUMEN

INTRODUCTION: Persistent symptoms have recently emerged as a clinical issue in COVID-19. We aimed to assess the prevalence and risk factors in symptomatic non-hospitalized individuals with mild COVID-19. METHODS: We performed a prospective cohort study of symptomatic COVID-19 outpatients, from March to May 2020, with weekly phone calls from clinical onset until day 30 and up to day 60 in case of persistent symptoms. The main outcomes were the proportion of patients with complete recovery at day 30 and day 60 and factors associated with persistent symptoms. RESULTS: We enrolled 429 individuals mostly women (72.5%) and healthcare workers (72.5%), with a median age of 41.6 years [IQR 30-51.5]. Symptoms included: cough (69.7%), asthenia (68.8%), anosmia (64.8%), headaches (64.6%), myalgia (62.7%), gastrointestinal symptoms (61.8%), fever (61.5%), and ageusia (60.8%). Mean duration of disease was 27 days (95%CI: 25-29). The rate of persistent symptoms was 46.8% at day 30 and 6.5% at day 60 consisting in asthenia (32.6%), anosmia (32.6%), and ageusia (30.4%). The probability of complete recovery was 56.3% (95%CI: 51.7-61.1) at day 30 and 85.6% (95%CI: 81.2-89.4) at day 60. Factors associated with persistent symptoms were age>40 (HR 0.61), female sex (HR 0.70), low cycle threshold (HR 0.78), and ageusia (HR 0.59). CONCLUSIONS: COVID-19 - even in its mild presentation - led to persistent symptoms (up to one month) in nearly half of individuals. Identification of risk factors such as age, gender, ageusia and viral load is crucial for clinical management and argues for the development of antiviral agents.

RESUMEN

OBJECTIVES: To describe the characteristics, evolution and risk factors for long-term persistence of olfactory and gustatory dysfunctions (OGD) in COVID-19 outpatients. PATIENTS AND METHODS: We conducted a prospective study in SARS-CoV-2 infected outpatients with OGD. Weekly phone interviews were set up starting from COVID-19 onset symptoms and over the course of 60 days, using standardized questionnaires that included a detailed description of general symptoms and OGD. The primary outcome was the proportion of patients with complete recovery of OGD at D30. Rate and time to recovery of OGD, as well as risk factors for late recovery (>30 days), were evaluated using Cox regression models. RESULTS: Ninety-eight outpatients were included. The median time to onset of OGD after first COVID-19 symptoms was 2 days (IQR 0-4). The 30-day recovery rate from OGD was 67.5% (95% CI 57.1-75.4) and the estimated median time of OGD recovery was 20 days (95% CI 13-26). Risk factors for late recovery of OGD were a complete loss of smell or taste at diagnosis (HR=0.26, 95% CI 0.12-0.56, P=0.0005) and age over 40 years (HR=0.56, 95% CI 0.36-0.89, P=0.01). CONCLUSIONS: COVID-19 patients with complete loss of smell or taste and over age 40 are more likely to develop persistent OGD and should rapidly receive sensorial rehabilitation.

RESUMEN

BACKGROUND: In recent years, dolutegravir monotherapy has been explored as a drug-reduced regimen for HIV patients. METHODS: This was a retrospective observational study, including patients virologically suppressed for ≥6 months, without previous virological failure (VF) under integrase inhibitors (INIs), who had been switched to dolutegravir monotherapy (50 mg/day). The primary aim was to report the proportion of VF at week 48 (W48) and week 96 (W96) of dolutegravir monotherapy. The evolution from baseline to W48 of residual viraemia on ultra-deep sequencing and HIV DNA was also evaluated. RESULTS: Sixty-one patients were included. Prior to switching to dolutegravir monotherapy, they had a median (IQR) of 15.4 (6.5-19.9) years of antiretroviral exposure, 5.8 (3.2-10.3) years of viral suppression and 687 (461-848) CD4+ cells/mm3. They remained on dolutegravir monotherapy for a median (IQR) of 100 (29-148) weeks. Forty-two out of 61 patients (68.9%) reached W48 and 32 out of 61 patients (52.5%) reached W96. VF occurred in three patients, with the emergence of INI resistance. VF occurred before W24 and in patients pre-exposed to INIs. At W48, the probability of VF (Kaplan-Meier analysis) was 5.6% (95% CI = 1.8%-16.4%). The same result was obtained at W96. Detectable residual viraemia did not increase and median HIV DNA did not change significantly (2.4 log/106 cells at baseline and 2.3 log/106 cells at W48). Dolutegravir plasma concentration was above the IC90 in 41/41 samples, from 22 patients. CONCLUSIONS: Long-term follow-up showed a low risk of VF under dolutegravir monotherapy, in a selected population of patients with previous long-term virological suppression and low HIV reservoir.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Background: Darunavir/ritonavir is a potent PI with a high genetic barrier and pharmacological robustness favourably investigated as monotherapy. Whether darunavir could be dose reduced in the context of monotherapy deserves investigation. Methods: Patients with HIV suppressed viraemia (plasma viral load <50 copies/mL for 12 months) under ART who had switched to darunavir/ritonavir monotherapy at 600/100 mg/day between 2013 and 2015 were included in this observational 48 week single-centre study. The primary outcome was the proportion of patients with virological success (defined as plasma viral load <50 copies/mL) at week 24. Secondary outcomes included treatment strategy success and resistance. Results: Thirty-one patients were included with the following baseline characteristics [median (IQR)]: age 52 years (47-57), CD4+ 649 cells/mm3 (463-813), ART duration 16.3 years (9.2-22.3), nadir CD4+ 195 cells/mm3 (144-261) and duration of HIV suppression 7.8 years (4.8-9.7). Prior to switch, ART consisted of PI monotherapy for 28 of 31 patients [darunavir/ritonavir 800/100 mg/day (n = 26), lopinavir/ritonavir (n = 1) and atazanavir/ritonavir (n = 1)] and a triple drug regimen for 3 of 31 patients. Within the 48 weeks of follow-up, no virological failure occurred and two patients discontinued 600/100 mg of darunavir/ritonavir due to side effects at week 16 and 40, leading to a virological suppression rate of 100% (95% CI = 89-100) at weeks 24 and 48. Strategy success rates were 96.8% (95% CI = 83.3-99.9) at week 24 and 93.5% (95% CI = 78.6-99.2) at week 48. Median (IQR) Ctrough values of 800/100 mg of darunavir/ritonavir and 600/100 mg of darunavir/ritonavir were 1537 ng/mL (1286-1724) and 1255 ng/mL (873-2161), respectively. Conclusions: A lower dose of darunavir/ritonavir used as monotherapy (600/100 mg/day) was highly effective in virologically suppressed HIV-infected patients. Further studies are needed to confirm these data.

RESUMEN

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.

RESUMEN

Background: Surveillance of HIV-1 resistance in treated patients with a detectable viral load (VL) is important to monitor, in order to assess the risk of spread of resistant viruses and to determine the proportion of patients who need new antiretroviral drugs with minimal cross-resistance. Methods: The HIV-1 protease and reverse transcriptase (RT) and integrase genes were sequenced in plasma samples from 782 consecutive patients on failing antiretroviral regimens, seen in 37 specialized centres in 2014. The genotyping results were interpreted using the ANRS v24 algorithm. Prevalence rates were compared with those obtained during a similar survey conducted in 2009. Results: The protease and RT sequences were obtained in 566 patients, and the integrase sequence in 382 patients. Sequencing was successful in 60%, 78%, 78% and 87% of patients with VLs of 51-200, 201-500, 501-1000 and >1000 copies/mL, respectively. Resistance to at least one antiretroviral drug was detected in 56.3% of samples. Respectively, 3.9%, 8.7%, 1.5% and 3.4% of patients harboured viruses that were resistant to any NRTI, NNRTI, PI and integrase inhibitor (INI). Resistance rates were lower in 2014 than in 2009. Resistance was detected in 48.5% of samples from patients with a VL between 51 and 200 copies/mL. Conclusion: In France in 2014, 90.0% of patients in AIDS care centres were receiving antiretroviral drugs and 12.0% of them had VLs >50 copies/mL. Therefore, this study suggests that 6.7% of treated patients in France might transmit resistant strains. Resistance testing may be warranted in all treated patients with VL > 50 copies/mL.

RESUMEN

BACKGROUND: Recent studies have independently implicated the chemokine CXCL12 and its receptors, CXCR4 and CXCR7, in the pathophysiology of Kaposi sarcoma (KS). OBJECTIVES: We investigated whether the CXCL12/CXCR4-CXCR7 protein trio could constitute KS biomarkers. METHODS: Endothelial and spindle cells positive for CXCL12/CXCR4-CXCR7, human herpesvirus-8 latency-associated nuclear antigen (LANA), Ki67 antigen (proliferation) and vascular endothelial growth factor (VEGF) were quantitated in skin lesions from patients with AIDS-associated KS, patients with classic KS and patients with angiomas, using immunohistochemistry and quantitative image analysis (16, 21 and 20 skin lesions, respectively). Plasma CXCL12 concentrations were measured by enzyme-linked immunosorbent assay from 20 patients with AIDS-KS, 12 HIV-infected patients without KS and 13 healthy donors' samples. RESULTS: Cells positive for CXCL12, CXCR4, CXCR7, LANA, Ki67 and VEGF were significantly enriched in patients with AIDS-associated KS and classic KS vs. angiomas (P < 0·001), and in nodular vs. macular/papular KS lesions (P < 0·05). CXCL12, CXCR4 and CXCR7 detection correlated with LANA, Ki67 and VEGF detection (r > 0·4; P < 0·05). However, plasma CXCL12 concentrations did not differ between patients with AIDS-associated KS, HIV-infected patients without KS, and healthy donors. CONCLUSIONS: The CXCL12/CXCR4-CXCR7 trio is upregulated in KS and correlates with KS pathophysiological markers and the severity of skin lesions. Histological assessment of the CXCL12 axis could serve as a valuable biomarker for KS diagnosis and progression.

RESUMEN

OBJECTIVES: The aim of the study was to evaluate the performance of Quantiferon Gold-In-Tube(®) (QFN) for the diagnosis of tuberculosis (TB) during hospitalization in an infectious diseases department. PATIENTS AND METHODS: QFN was performed in 245 patients recently hospitalized for suspected TB. Subsets of patients underwent tuberculin skin tests (TST), and microbiological cultures were performed. RESULT: TB was diagnosed in 57 (23%) patients: pulmonary in 23 (40%), extrapulmonary in 16 (28%), and disseminated in 18 (32%). Seventeen (30%) of these TB patients were immunocompromised, including 12 with HIV infection. The sensitivity of QFN was 74%, its specificity 56%, its positive predictive value 43% and negative predictive value (NPV) 92%. The sensitivity was similar in pulmonary and extrapulmonary TB but lower in disseminated TB, although not significantly so. The sensitivity was also lower (P=0.04) in immunocompromised patients. The specificity was lower in migrants than in native French patients (P=0.01), and lower in patients with a history of TB than in those without (P<0.001). Finally, combining culture with QFN significantly increased the sensitivity (P=0.008), and produced a higher NPV, as for the combination with TST, but not significantly different than with QFN alone. CONCLUSION: The performance of QFN was weak in this context, especially in subgroups at high risk for latent TB. However, combined negative results of QFN or TST and culture could be useful to rule out active TB.

RESUMEN

BACKGROUND: Etravirine (ETR) is recommended as twice-daily dosing in pretreated patients. There are no data regarding the use of ETR once daily in HIV-experienced patients with prior resistance to first-generation non-nucleoside reverse transcripase inhibitors (NNRTIs). OBJECTIVES: To evaluate the capacity of once-daily ETR to maintain suppressed viremia over 48 weeks after switching from ETR twice daily in NNRTI-experienced patients. METHODS: In this pilot open-label study, patients with plasma viral load (pVL) <50 copies/mL on a stable ETR 200 mg bid regimen were enrolled to switch to ETR 400 mg qd and followed up over 48 weeks. The primary endpoint was the proportion of patients with pVL <50 copies/mL at week 24. Secondary endpoints included the rate of pVL< 50 copies/mL at week 48, ETR pharmacokinetic parameters, and tolerability and resistance profile. RESULTS: Twenty-four patients were included. They had extensive antiretroviral treatment for a median of 14 years (range, 1-19). All except for 2 had prior resistance to NNRTIs. Seven patients discontinued ETR once daily prior to week 48 for virological failure (3), protocol deviation (3), and side effects (1). At week 24, 95% of patients maintained pVL< 50 copies/mL (95% CI, 78.4-99.7) and 85% at week 48 (95%CI, 65.6-95.8). Two of the 3 patients with virological failure had ETR resistance mutations prior to initiation. The median ETR C(trough) level remained stable after switching from twice daily 515 ng/mL (340-758) to once daily 422 ng/mL (264-655). CONCLUSION: These results suggest that ETR is effective as a once-daily regimen in patients with prior NNRTI experience when HIV is sensitive to ETR. The stability of C(trough) concentrations on a once-daily regimen confirms the once-daily profile of the drug in experienced patients.
