RESUMEN
In this placebo-controlled phase II randomized clinical trial, 103 human immunodeficiency virus type 1 (HIV-1)-infected patients under cART (combined antiretroviral treatment) were randomized 2:1 to receive either 3 doses of DNA GTU-MultiHIV B (coding for Rev, Nef, Tat, Gag, and gp160) at week 0 (W0), W4, and W12, followed by 2 doses of LIPO-5 vaccine containing long peptides from Gag, Pol, and Nef at W20 and W24, or placebo. Analytical treatment interruption (ATI) was performed between W36 to W48. At W28, vaccinees experienced an increase in functional CD4+ T-cell responses (P < 0.001 for each cytokine compared to W0) measured, predominantly against Gag and Pol/Env, and an increase in HIV-specific CD8+ T cells producing interleukin 2 (IL-2) and tumor necrosis factor alpha (TNF-α) (P = 0.001 and 0.013, respectively), predominantly against Pol/Env and Nef. However, analysis of T-cell subsets by mass cytometry in a subpopulation showed an increase in the W28/W0 ratio for memory CD8+ T cells coexpressing exhaustion and senescence markers such as PD-1/TIGIT (P = 0.004) and CD27/CD57 (P = 0.044) in vaccinees compared to the placebo group. During ATI, all patients experienced viral rebound, with the maximum observed HIV RNA level at W42 (median, 4.63 log10 copies [cp]/ml; interquartile range [IQR], 4.00 to 5.09), without any difference between arms. No patient resumed cART for CD4 cell count drop. Globally, the vaccine strategy was safe. However, a secondary HIV transmission during ATI was observed. These data show that the prime-boost combination of DNA and LIPO-5 vaccines elicited broad and polyfunctional T cells. The contrast between the quality of immune responses and the lack of potent viral control underscores the need for combined immunomodulatory strategies. (This study has been registered at ClinicalTrials.gov under registration no. NCT01492985.)IMPORTANCE In this placebo-controlled phase II randomized clinical trial, we evaluated the safety and immunogenicity of a therapeutic prime-boost vaccine strategy using a recombinant DNA vaccine (GTU-MultiHIV B clade) followed by a boost vaccination with a lipopeptide vaccine (HIV-LIPO-5) in HIV-infected patients on combined antiretroviral therapy. We show here that this prime-boost strategy is well tolerated, consistently with previous studies in HIV-1-infected individuals and healthy volunteers who received each vaccine component individually. Compared to the placebo group, vaccinees elicited strong and polyfunctional HIV-specific CD4+ and CD8+ T-cell responses. However, these immune responses presented some qualitative defects and were not able to control viremia following antiretroviral treatment interruption, as no difference in HIV viral rebound was observed in the vaccine and placebo groups. Several lessons were learned from these results, pointing out the urgent need to combine vaccine strategies with other immune-based interventions.

OBJECTIVES: The aim of the study was to assess whether the timing of combination antiretroviral therapy (cART) initiation, the choice of cART and virological response differ in migrants versus European natives in the north and east of Paris area, after dissemination of French recommendations for universal treatment. METHODS: Antiretroviral therapy-naïve HIV-1-infected adults with at least two follow-up visits at one of 15 participating centres between 1 January 2014 and 31 March 2015 were included in the study. Factors associated with cART initiation before 31 March 2015, with protease inhibitor (PI)-containing cART among individuals initiating cART, and with 1-year virological success after cART initiation were assessed using multivariable logistic regression models. Sex, age, region of origin [Western Europe, sub-Saharan Africa (SSA) or other], HIV transmission group, baseline AIDS status, CD4 cell count and plasma viral load (VL), and hepatitis B and/or C virus infection were considered in the analyses. RESULTS: Among 912 individuals, only 584 (64%) started cART during the study period. After adjustment, migrants from SSA were half as likely to initiate cART and to have a subsequent virological response compared with individuals from Western Europe [adjusted odds ratio (aOR) 0.54; 95% confidence interval (CI) 0.36-0.82; and aOR 0.52; 95% CI 0.28-0.98, respectively]. PI-containing cART was more frequently prescribed in migrants from SSA, in people with lower CD4 cell counts and in people with higher VL. CONCLUSIONS: Even in the context of universal cART recommendations and of free access to care, migrants from SSA still have delayed access to cART and a lower virological response. Efforts are still necessary to provide immediate cART to all people living with HIV.

Staphylococcus aureus (SA) is the leading cause of bloodstream infection (BSI). The incidence of methicillin-resistant SA (MRSA) has decreased in France and Europe since one decade. Early and precise prediction of methicillin susceptibility is needed to improve probabilistic antibiotic therapy of MRSA-BSI. The aim of this study was to identify MRSA-BSI risk factors at admission and evaluate which patients need costly rapid diagnostic tests. A single-center retrospective descriptive study of all diagnosed SA-BSI was conducted in a French University Hospital between January 2015 and December 2016. All medical charts were reviewed. Univariate and multivariate analyses by a logistic regression model were performed on the data. We then build a prediction score of MRSA-BSI by assigning one point for each of the risk factor identified. During the study period, 151 SA-BSI were identified including 32 (21%) MRSA-BSI. In multivariate analysis, three factors were associated with MRSA-BSI: coming from long-term care facility, known previous MRSA colonization and/or infection, and chronic renal disease. Among our population, respectively, 5% and 100% had a MRSA-BSI when no or three risk factors were identified. Therefore, among the PCR performed, 43 (96%) could be avoided according to our clinical score. In our study, methicillin-susceptible SA and MRSA-BSI can be predictable by counting MRSA risk factors. This prediction rule could avoid the use of expensive rapid diagnostic tests. Prospective studies and prediction rules could help physicians to predict SA-BSI susceptibility to improve appropriate empiric therapy choice.

Tuberculous meningitis (TBM) is the most lethal and disabling form of tuberculosis. In 2017, approximately 10 million people developed TB worldwide, of whom more than 100,000 new cases of TBM are estimated to occur per year. In patients who are co-infected with HIV-1, TBM has a mortality approaching 50%. Diagnosis of TBM is often delayed by the insensitive and lengthy culture technique required for disease confirmation. GeneXpert represents the most significant advance in TBM diagnostics over the past decade, but it lacks sensitivity and cannot be used to rule out the diagnosis. Higher volume of cerebrospinal fluid (CSF) seems to be interesting to improve the diagnosis performances. New rapid and accurate diagnostic tools are necessary. Better advances have been made concerning the anti-tuberculosis chemotherapy of TBM, with the publication of clinical trials and pharmacokinetic studies exploring the use of higher rifampicin doses and fluoroquinolones. The rise of drug-resistant TBM is another challenge for management because TBM caused by multidrug resistant organisms results in death or severe disability in almost all sufferers.

Healthy travellers to countries where carbapenemases-producing Enterobacteriaceae (CPE) are endemic might be at risk for their acquisition, even without contact with the local healthcare system. Here, we report the acquisition of CPE (two OXA-181, one New Delhi metallo-beta-lactamase 1 (NDM-1)) in three healthy travellers returning from India. The duration of CPE intestinal carriage was less than one month. The results indicate that healthy travellers recently returning from India might be considered as at risk for CPE carriage.

OBJECTIVES: The aim of the study was to demonstrate the noninferiority of polyacrylamide hydrogel (PH) vs. polylactic acid (PLA) for the treatment of facial lipoatrophy in HIV-infected adults. METHODS: A randomized, blinded, multicentre, noninferiority 96-week study was carried out. Patients with facial lipoatrophy were randomly assigned to receive intradermal injections with PH or PLA, and were blinded to the filler. The primary efficacy endpoint was patient satisfaction at week 48 assessed using a visual analogue scale score (VAS). Secondary efficacy end-points included cheek thickness and skin-fold, lipoatrophy grading and quality of life. Safety was assessed by the reporting of adverse events. RESULTS: A total of 148 patients were included in the study; 93% were men, the median age was 47 years, the median CD4 count was 528 cells/µL, and the median duration of antiretroviral therapy was 12 years. Mean VAS increased from 2.8 at baseline to 7.1 and 7.5 in the PLA and PH arms, respectively, at week 48 (P=0.0002 for noninferiority) and was sustained at week 96 (6.7 and 7.9 in the PLA and PH arms, respectively; P=0.003 for noninferiority). Cheek thickness and skin-fold increases and lipoatrophy improvement were similar in the two arms. Quality of life remained unchanged or improved depending on the questionnaire used. In injected patients, subcutaneous nodules emerged in 28 (41%) and 26 (37%) patients in the PLA and PH arms, respectively (P=0.73). Four patients in the PH arm developed severe inflammatory nodules, a median of 17 months after the last injection. CONCLUSIONS: PH and PLA have similar efficacies in the treatment of facial lipoatrophy, but PH may be associated with more delayed inflammatory nodules.

BACKGROUND: Many HIV-treated patients travel to malaria-infected zones, but very few data are available on potential interactions between antiretroviral and antimalarial drugs. METHOD: We performed a pharmacokinetic study on the interaction of doxycycline (100 mg/d) on 2 protease inhibitors (PIs), atazanavir and lopinavir, and 2 non-nucleoside reverse transcriptase inhibitors (NNRTIs), efavirenz and nevirapine, given at usual daily doses in HIV-infected migrants native from sub-Saharan Africa included in the VIHVO ANRS-study before travelling to a sub-Saharan country. Antiretroviral trough plasma concentrations were measured at enrollment visit during the month preceding the travel before doxycycline introduction and on the week following the patients' return to France when they had been taking doxycycline for at least 15 days. Impact of doxycycline on antiretroviral concentrations was tested either with antiretroviral drugs separately or within the therapeutic classes (PI or NNRTI) in patients with an HIV RNA level <50 copies/mL at both visits and with good declared adherence. The Two One-Sided Test that was adapted to the Wilcoxon test was used to evidence the lack of interaction. Sixty-five patients receiving regimens containing atazanavir (n = 1), ritonavir-boosted atazanavir (n = 14), ritonavir-boosted lopinavir (n = 23), efavirenz (n = 17), nevirapine (n = 10) were included. RESULTS: Lack of pharmacokinetic interaction was statistically significant when tested by therapeutic class (PI, P = .02; NNRTI, P = .005) and was not demonstrated for each antiretroviral when tested separately. CONCLUSION: This study is the first to assess the interaction of doxycycline on PI and NNRTI. This lack of pharmacokinetic interaction supports the choice of doxycycline as the antimalarial drug in patients treated with PI or NNRTI.

PURPOSE: Data on the microbiological epidemiology of Intra-Abdominal Abscesses (IAAs) are very scarce. We aimed to study the microbiological epidemiology of these infections in order to optimize empirical antibiotic therapy. PATIENTS AND METHODS: Between January 2015 and December 2020, we retrospectively analyzed all IAAs files in our hospital. Clinical and microbiological data such as antibiotic susceptibilities were collected. RESULTS: We studied 243 IAA cases. All in all, 139 (57.2%) IAAs were healthcare-associated and 201 (82.7%) were drained. The highest risk situations for IAAs were appendicitis (n = 69) and diverticulitis (n = 37). Out of the 163 microbiologically documented infections, 136 (81.9%) were polymicrobial. Enterobacterales (n = 192, 36.1%), Enterococcus sp. (n = 84, 17.6%) and anaerobes (n = 66, 16.1%) were the most frequently identified bacteria. Gram-negative bacteria were susceptible to amoxicillin-acid clavulanic, piperacillin-tazobactam, cefotaxime, meropenem in 55.2%, 84.9%, 77.6% and 99.5% of cases, respectively. Concerning Gram-positive bacteria, the susceptibility rate was 81.8% for amoxicillin-clavulanic acid, piperacillin-tazobactam and meropenem, and decreased to 63.4% for cefotaxime. CONCLUSION: This study highlights the polymicrobial profile of IAAs and their low susceptibility to amoxicillin and clavulanic acid. The piperacillin-tazobactam association remained the most appropriate empirical antibiotic therapy.

OBJECTIVES: Patients lost to follow-up and treatment failure in tuberculosis disease (TB) are major public health issues. In the absence of appropriate treatment, approximately 70 % of smear-positive patients will die within 10 years of disease progression. This study, conducted in the French region with the highest incidence, aimed to assess tuberculosis treatment outcomes and its determinants. PATIENTS AND METHODS: A prospective, multicenter cohort study (CO1TB) of adults and children treated for TB was conducted in four hospitals in the North of Paris. Treatment outcome at 1 year and associated socioeconomic and clinical factors were studied by multivariate logistic regression. RESULTS: Among 145 TB cases included from May 2018 to January 2020, patients were mainly born abroad and most lived in difficult socioeconomic conditions. During treatment, 25/145 (17 %) patients experienced adverse effects, which were not significantly associated with discontinuation of treatment (p = 0.99). At 1 year, 114 (78 %) had completed treatments, 26 (19 %) were lost to follow-up, three (2.1 %) were still being treated and two (1.4 %) had died. In the multivariate analysis, a history of TB was significantly associated with unfavorable treatment outcome (aOR = 5.3, 95 %CI (1.5;18.6) and a trend towards significance (p < 0.2) was observed among patients aged under 24 years (aOR = 2.9, 95 %-CI 0.95;8.5). CONCLUSION: In this precarious population, socioeconomic conditions were not found to be associated with unfavorable treatment outcome, whereas history of tuberculosis and young age played a role. Increased monitoring is thus required for these patients.

OBJECTIVE: To identify tools that will result in faster diagnosis, making the current pulmonary tuberculosis strategy more efficient. PATIENTS AND METHODS: A 4-year (2015-2018) retrospective study. The gold standard for diagnosis was a positive culture from a respiratory specimen. All sputum, fibroscopy and post-fibroscopy specimens (for smear negative patients) were collected. Each specimen was analyzed through smear examination and culture. All nucleic acid amplification testing results were included. Analyses looked at the incremental yield of positive cases of each successive specimen collection, and time to diagnosis. RESULTS: A total of 354 patients had at least one positive culture. Sputum allowed a diagnosis in 92% of cases (including a gain in sensitivity of around 7% for the third sputum specimen), with 160 smear-positive patients (45%). Among smear-negative patients, 109 underwent a fibroscopy procedure (culture sensitivity of 75%), and 59 had a post-fibroscopy specimen collected, which together identified the rest of the patients (8%). Molecular testing was used in 237 specimens. Median time to diagnosis was 11 days, which was significantly reduced among smear-negative patients when molecular testing was used (P<0.001). Shortening the delay between sputum specimen collections did not alter procedure sensitivity. CONCLUSIONS: We identified several aspects of the French tuberculosis diagnosis algorithm that could be improved, and posed the basis for a prospective study. Centers in higher incidence areas could benefit from a dedicated, predefined procedure exploring suspicions of tuberculosis. A high suspicion score of tuberculosis could drive the reasoned use of molecular testing in such settings.

In late February-early April 2010, five cases of dengue fever were diagnosed in returning travellers in Europe in EurotravNet sites in Sweden and France in patients with travel history to the Comoros and/or Zanzibar, Tanzania. Four cases were non-complicated dengue fever and one case dengue hemorrhagic fever. Three patients were viraemic at the time of diagnosis and infected with Dengue type 3 virus.

In Burundi, like in many other resource-limited settings, HIV sector is mainly financed by international funding (IF). Through this way, HIV-infected people may have access to care, antiretroviral therapy and opportunistic infections medications free of charge. In addition, IF can also contribute to major the HIV-health care professionals (HCP) salary. Indeed, because of dramatically low incomes, public sector HCP move frequently through the country or migrate towards foreign countries, attracted by higher salaries and better working environment. To date, relatively large funding became available in some settings for HIV-care. Through illustrative examples from the field in Burundi, we are discussing why consequences are, in many cases, a worsening of inequities and disorganization of the public health sector, instead of leading this latter one towards a global improvement. Furthermore, we are suggesting that HIV-programs per se are not sufficient to provide a proper management of the epidemic at a global scale.

Prevention of malaria is based on personal vector-control measures (PVCMs) to avoid mosquito bites at night and chemoprophylaxis if justified by the risk of contracting the disease. The most effective PVCM is the use of insecticide-treated mosquito nets. The decision to prescribe chemoprophylaxis, mainly to prevent Plasmodium falciparum infection, depends on the benefit-risk ratio. Overall, the risk of contracting malaria is 1,000-fold lower during a stay in the tropical regions of Asia or the Americas than in sub-Saharan Africa. For "conventional" stays (less than one month with nights spent in urban areas) in low-risk settings in tropical Asia and America, the risk of being infected with Plasmodium parasites (≤1/100,000) is equivalent or lower than that of experiencing serious adverse effects caused by chemoprophylaxis. Preventive medication is therefore no longer recommended. By contrast, in other settings and particularly in sub-Saharan Africa, chemoprophylaxis is the most effective measure against malaria. However, it is worth noting that no single preventive measure provides full protection. Regardless of the level of risk or chemoprophylaxis-related indication, protection against mosquito bites and rapid management of febrile illness after returning from an endemic area are also critical to prevent malaria. Finally, migrants of sub-Saharan origin visiting friends and relatives in their country of origin form a high-risk group who should be recommended chemoprophylaxis in the same way as any other travelers-with a preference for the least expensive molecules (doxycycline).

Hyperreactive malarial splenomegaly (HMS) is the chronic stage of a long-term stimulation of the immune system secondary to plasmodial infections, more frequently in genetically predisposed patients. HMS is a leading cause of large tropical splenomegaly in endemic zones but has been described in immigrants from Africa and in some European expatriates living in endemic countries. Diagnostic criteria include: long-term stay in a endemic zone, often large splenomegaly, high IgM titer, high antiplasmodial antibody titer, regression by at least 40% of splenomegaly six months after curative antimalarial treatment. In tropical settings, B-cell lymphoma and splenic lymphoma are the main differential diagnoses, which may be identified by a clonality analysis. Recent studies suggest that HMS can be treated by a short-term antimalarial therapy as long as the patient resides out of a malarial endemic country.

OBJECTIVES: To describe the residual broncho-pulmonary lesions and evaluate the role of CT scanning at the end of treatment of pulmonary tuberculosis. MATERIALS AND METHODS: Analysis of the initial and end of treatment CT scans of 56 patients with pulmonary tuberculosis according to a reading grid including parenchymatous and airways lesions. The CT data at the end of treatment were analysed in relation to the clinical and microbiological data, and the original CT scan. RESULTS: Active lesions (thick walled cavities and/or centrilobular micronodules) persisted in 24 patients (43%) after a mean treatment period of 7 months. The persistence of these signs of activity was correlated with the initial presence of a cavitary syndrome (p=0.027), with predominant sub-segmentary bronchial involvement, with extensive micronodular spread (p=0.024) and with bronchiectasis (p=0.04). These residual lesions were not associated with an increased risk of relapse. CONCLUSION: The persistence of signs of activity on the CT scan at the end of treatment of tuberculosis do not necessarily correspond to an absence of cure but to a radiological delay. This imaging is nevertheless useful to make an assessment of any subsequent changes in the bronchial tree and to estimate the risk of later complications.

Immigrants living in France account for one third of new cases of infection and are a target population for prevention. Care givers should adapt their management practice, taking into account this population's specificities which are not restricted to cultural differences but include major socioeconomic factors. In addition to training on alien rights and basic sociocultural knowledge, care-givers (especially clinicians) must spend more time with the patient (especially at the beginning of the relationship) and accept sharing the "medical power" with other people with a better knowledge of other aspects of the patients' life in addition to the medical one. As in other chronic diseases, mediation is one of the available tools with evident benefits for any patient. Assuming compliance is the same for migrants as for other patients, using this mediation will warrant therapeutic success.

An observational prospective cohort study assessed malaria risk perception, knowledge and prophylaxis practices among individuals of African ethnicity living in Paris and travelling to their country of origin to visit friends or relatives (VFR). The study compared two groups of VFR who had visited a travel clinic (TC; n=122) or a travel agency (TA; n=69) before departure. Of the 47% of VFR citing malaria as a health concern, 75% knew that malaria is mosquito-borne and that bed nets are an effective preventive measure. Perception of high malaria risk was greater in the TA group (33%) than in the TC group (7%). The availability of a malaria vaccine was mentioned by 35% of VFR, with frequent confusion between yellow fever vaccine and malaria prevention. Twenty-nine percent took adequate chemoprophylaxis with complete adherence, which was higher among the TC group (41%) than the TA group (12%). Effective antivector protection measures used were bed nets (16%), wearing long clothes at night (14%) and air conditioning (8%), with no differences between the study groups except in the use of impregnated bed nets (11% of the TC group and none of the TA group). Media coverage, malaria chemoprophylaxis repayment and cultural adaptation of preventive messages should be improved to reduce the high rate of inadequate malaria prophylaxis in VFR.

BACKGROUND: Recommendations for improving traveler adherence address both the content of the advice given and the structure of the consultation. The objective of this article is to describe how travel health consultations are structured in France. METHODS: A questionnaire based on both theoretical foundations and recommendations in the literature was sent to health professionals who practice in travel clinics, all of them members of France's Société de Médecine des Voyages. RESULTS: The response rate was 78.5% (176/224). One hundred thirty nine respondents (78.9%) reported that treatment (vaccinations, in particular) and advising were done at separate times in the consultation. The majority of respondents questioned the traveler on his wishes, difficulties, expectations, experiences, and previous knowledge. A third explored the traveler's perceptions regarding the seriousness of diseases, the effectiveness of prevention measures and the latter's adverse effects with a difference when health professionals were practicing >5 years and/or had received specific training ( P < 0.05). At the end of the consultation, 92% of the respondents asked the traveler whether he understood the advice given. One hundred thirty seven respondents (77.8%) gave travelers a booklet with additional advice, and 66.5% gave them a website where they could find health advice on their destination. Travelers were almost never offered group consultations or the opportunity to work on real-life situations. When there were language barriers, the respondents were more likely to seek help from a French-speaking member of the traveler's entourage (48.9%) than from an interpreter (22.7%). CONCLUSIONS: While the majority of practitioners follow most of the recommendations regarding the structure of travel health consultations, some of the factors that enhance traveler learning are underutilized, reducing the likelihood that travelers will apply the advice given. The study illustrates the need to develop more educational intervention methods and to evaluate their impact on travelers.

To estimate rates and identify correlates of HIV disclosure in migrants from sub-Saharan Africa (SSA) successfully treated, a sub-analysis was conducted in HIV-1 native SSA migrants, living in France with undetectable viral load on antiretroviral, included in the VIHVO adherence study. Logistic regression models assessed factors associated with HIV disclosure. Among 246 individuals (40 % male, median age 41), 79 % of those in a steady heterosexual partnership (n = 167) had disclosed their status to their partner, 55 % of the total 246 to a relative, and 33 % to (an)other person(s). Disclosure to one's steady partner was associated with a follow-up duration since HIV diagnosis of more than 5 years, a higher literacy level, a better social context and marital status. Women were more likely to disclose their HIV status to relatives. Interventions targeting this population should be provided to improve disclosure which in turn ensures better social support, testing of the partner and lower rates of undiagnosed HIV.
