ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Background: Patients diagnosed with advanced HIV infection have a poor prognosis despite initiation of combined antiretroviral therapy (c-ART). Objective: To assess the benefit of adding maraviroc, an antiretroviral drug with immunologic effects, to standard c-ART for patients with advanced disease at HIV diagnosis. Design: Randomized controlled trial. (ClinicalTrials.gov: NCT01348308). Setting: Clinical sites in France (n = 25), Italy (n = 5), and Spain (n = 20). Participants: 416 HIV-positive, antiretroviral-naive adults with CD4 counts less than 0.200 × 109 cells/L and/or a previous AIDS-defining event (ADE). Intervention: C-ART plus placebo or maraviroc (300 mg twice daily with dose modification) for 72 weeks. Measurements: The primary end point was first occurrence of severe morbidity (new ADE, selected serious infections, serious non-ADE, immune reconstitution inflammatory syndrome, or death). Prespecified secondary outcomes included primary outcome components, biological and pharmacokinetic measures, and adverse events graded 2 or higher. Results: 409 randomly assigned participants (207 in the placebo group and 202 in the maraviroc group) who received more than 1 dose were included in the analysis. During 72 weeks of follow-up, incidence of severe morbidity was 11.1 per 100 person-years in the maraviroc group and 11.2 per 100 person-years in the placebo group (hazard ratio, 0.97 [95% CI, 0.57 to 1.67]). Incidence of adverse events graded 2 or higher was 36.1 versus 41.5 per 100 person-years (incidence rate ratio, 0.87 [CI, 0.65 to 1.15]). Limitations: Sixty-four participants discontinued therapy during follow-up. The study was not designed to evaluate time-dependent outcomes or effect modification. Conclusion: Addition of maraviroc to standard c-ART does not improve clinical outcomes of patients initiating therapy for advanced HIV infection. Primary Funding Source: INSERM-ANRS (French National Agency for Research on AIDS).

ABSTRACT

We investigated the presence of stop codons (SC) and/or hypermutation (HM) in HIV-1 DNA sequences generated for routine drug resistance testing in proviral HIV-1 DNA, and sought for associated factors. At least one SC was identified in 6.2% of HIV-1 DNA sequences, among which 54.8% were hypermutated. The defective virus group (SC w/o HM) was similar to the non-SC group regarding the characteristics of HIV-1 infection, and before drug exposure. In addition, the HIV-1 DNA levels were not different between both groups. Sequences with SC/HM displayed a higher proportion of RAMs. The impact of the SC/HM associated RAMs on clinical responses requires further investigation.

ABSTRACT

OBJECTIVES: Since February 2017, an increase of acute hepatitis A (AHA) cases has been notified in North of France. We aimed to report clinical and virological features of 49 cases treated in three hospitals in Lille European Metropolis (LEM). METHODS: All adult patients treated for AHA in 3 LEM hospitals between 20 February and 5 July 2017 were included. Demographic characteristics, exposure risk factors to hepatitis A virus (HAV), AHA manifestations and concomitant sexually transmitted infections (STI) were retrospectively recorded. RESULTS: Forty-nine cases of AHA were diagnosed among which 34 (69%) were hospitalised. Severe AHA occurred in 7 (14%) patients. The median age of cases was 36 years. All cases except 1 were men and 32 (65%) were identified as men having sex with men (MSM). Eleven (23%) patients were HIV-infected, 5 were under HIV pre-exposure prophylaxis (PrEP), 6 had a history of HIV postexposure prophylaxis and 19 had a history of at least one STI. Only three patients had received HAV vaccine. Proportion of patients tested for syphilis, chlamydial and gonococcal infections was 75% (18/24) in those seen by sexual health specialists and 21% (6/29) in those seen by other specialists. At least one concomitant STI was diagnosed in 13 out of 24 tested patients (54%). RT-PCR sequencing was available for 38 cases and confirmed co-circulation of 3 different strains of subgenotype IA (VRD 521 2016: n=24, RIVM-HAV16-090: n=13, V16-25801: n=1), already identified in several European countries. CONCLUSIONS: We are facing an outbreak of AHA among MSM in the North of France with a high rate of hospitalisation. Analysis of cases highlighted missed opportunities of vaccination and lack of concomitant STI screening. Awareness among healthcare providers and MSM should be increased and HAV vaccination promoted.

ABSTRACT

BACKGROUND: The circumstances of prescription of tropism tests clinically relevant in treatment-experienced patients are unclear. METHODS: We performed a monocentric retrospective analysis of all tropism tests performed between 2006 and 2015 in HIV-infected patients on antiretroviral therapy (ART) without MVC. The motivation of tropism determination was collected. Factors associated with MVC prescription were determined using logistic regression analysis. RESULTS: Five hundred sixty-three tests were performed in experienced patients not receiving MVC. Reasons for tropism performance were: virological failure (44%), side effects or drug-interactions (37%), simplification or sparing strategies (11%), immunological failure (5%), and improvement of neurological diffusion (3%). MVC was prescribed in 110 cases (20%), though 366 tests (65%) revealed a tropism CCR5. MVC was more often prescribed before 2011 (OR 3.65, 95% CI 2.17-6.13) and in patients with multiple previous ART regimens (less than 4 ART regimens compare to more than 10 ART regimens (OR 0.34, 95% CI 0.15-0.74)). CONCLUSIONS: In experienced patients not receiving MVC, tropism test prescription should be restricted to patients with virological failure and limited therapeutic options such as patients already treated with a wide range of ART regimens.

ABSTRACT

INTRODUCTION: Mycobacterium mucogenicum is a rare but emerging cause of infections, especially in immunocompromised patients. CASE PRESENTATION: We describe a new case of M. mucogenicum catheter-related bloodstream infection in a 34-year-old woman with ovarian cancer. M. mucogenicum was at first considered as a contaminant, and susceptibility testing was not performed. Usual susceptibility of M. mucogenicum motivated prescription of clarithromycin and moxifloxacin. Finally, our isolate was confirmed susceptible to both drugs. Clinical outcome was favorable with no relapse of infection after antibiotics discontinuation despite concomitant chemotherapy. CONCLUSION: Our case illustrates the need for a clinician-microbiologist dialogue in case of suspected M. mucogenicum infection to avoid delaying appropriate management.

ABSTRACT

BACKGROUND: Community-onset candidemia constitute a distinct clinical entity the incidence of which is increasing. Contribution of non-albicans Candida species is rising. CASE PRESENTATION: We describe here the first reported case of community acquired fungemia due to Candida pulcherrima. Identification to the species level was performed by MALDI-TOF mass spectrometry. Treatment with fluconazole was successful. CONCLUSION: This case confirms the pathogenic role of C. pulcherrima and the contribution of MALDI-TOF mass spectrometry for identification of rare Candida species.

ABSTRACT

BACKGROUND: Mortality associated with aortic graft infection is considerable. The gold standard for surgical treatment remains explantation of the graft. However, prognostic factors associated with early mortality due to this surgical procedure are not well-known. METHODS: Retrospective analysis of patients admitted in our center between January 2006 and October 2011 for aortic graft infection. The primary endpoint was in-hospital mortality. A bivariate analysis of characteristics of patients associated with in-hospital outcome was performed. RESULTS: Twenty five evaluable patients were studied. All patients were male. Their mean age was 67 ± 8.4 years. Most of them (92%) had severe underlying diseases. An in situ prosthetic graft replacement, mainly using cryopreserved arterial allografts, was performed in all patients, excepted one who underwent extra-anatomic bypass. Causative organisms were identified in 23 patients (92%). The in-hospital mortality rate was 48%. Among pre-operative characteristics, age ≥ 70 years, creatinine ≥ 12 mg/L and C reactive protein ≥ 50 mg/L were significantly associated with in-hospital mortality. Hospital mortality rates increased with the number of risk factor present on ICU admission, and were 0%, 14.3%, 85.7% and 100% for 0, 1, 2 and 3 factors, respectively. The only intra-operative factor associated with prognosis was an associated intestinal procedure due to aorto-enteric fistula. SAPS II, SOFA score and occurrence of medical or surgical complications were postoperative characteristics associated with in-hospital mortality. CONCLUSION: Morbidity and mortality associated with surgical approach of aortic graft infections are considerable. Age and values of creatinine and C Reactive protein on hospital admission appear as the most important determinant of in hospital mortality. They could be taken into account for guiding the surgical strategy.

ABSTRACT

OBJECTIVES: We aimed to assess the frequency, management, and burden of enterococcal-related vascular graft infection. PATIENTS AND METHODS: From 2008 to 2021, data regarding all episodes of vascular graft infections initially managed or secondarily referred to our referral center were prospectively collected. We described the history and management of the infection, depending on the type of prosthesis used. RESULTS: The frequency of enterococcal-related vascular graft infections was 29/249 (12 %). Most of them were early infections (22/29, 76 %). Infections were polymicrobial (26/29, 90 %), mostly associated with Enterobacterales. Among patients with positive blood cultures, 7/8 (88 %) involved enterococci. Patients with enterococcal-related vascular graft infections were mainly (22/29, 76 %) treated with an association of antibiotics. Mortality and relapse occurred in 28 % and 7 % respectively of the cases. CONCLUSIONS: Enterococcal-related vascular graft infections occurred in patients with comorbidities, during the early period following surgery and were more frequent in cases of intra-cavitary prosthesis. Their potential virulence needs to be considered, especially in polymicrobial infections.

ABSTRACT

OBJECTIVES: The vast majority of ICU patients require some form of venous access. There are no evidenced-based guidelines concerning the use of either central or peripheral venous catheters, despite very different complications. It remains unknown which to insert in ICU patients. We investigated the rate of catheter-related insertion or maintenance complications in two strategies: one favoring the central venous catheters and the other peripheral venous catheters. DESIGN: Multicenter, controlled, parallel-group, open-label randomized trial. SETTING: Three French ICUs. PATIENTS: Adult ICU patients with equal central or peripheral venous access requirement. INTERVENTION: Patients were randomized to receive central venous catheters or peripheral venous catheters as initial venous access. MEASUREMENTS AND RESULTS: The primary endpoint was the rate of major catheter-related complications within 28 days. Secondary endpoints were the rate of minor catheter-related complications and a composite score-assessing staff utilization and time spent to manage catheter insertions. Analysis was intention to treat. We randomly assigned 135 patients to receive a central venous catheter and 128 patients to receive a peripheral venous catheter. Major catheter-related complications were greater in the peripheral venous catheter than in the central venous catheter group (133 vs 87, respectively, p=0.02) although none of those was life threatening. Minor catheter-related complications were 201 with central venous catheters and 248 with peripheral venous catheters (p=0.06). 46% (60/128) patients were managed throughout their ICU stay with peripheral venous catheters only. There were significantly more peripheral venous catheter-related complications per patient in patients managed solely with peripheral venous catheter than in patients that received peripheral venous catheter and at least one central venous catheter: 1.92 (121/63) versus 1.13 (226/200), p<0.005. There was no difference in central venous catheter-related complications per patient between patients initially randomized to peripheral venous catheters but subsequently crossed-over to central venous catheter and patients randomized to the central venous catheter group. Kaplan-Meier estimates of survival probability did not differ between the two groups. CONCLUSION: In ICU patients with equal central or peripheral venous access requirement, central venous catheters should preferably be inserted: a strategy associated with less major complications.

ABSTRACT

BACKGROUND: The present study was performed to assess the prognosis of patients admitted to the intensive care unit (ICU) for community acquired pneumonia (CAP) after implementation of new processes of care. METHODS: Two groups of patients with CAP were admitted to a 16-bed multidisciplinary ICU in an urban teaching hospital during two different periods: the years 1995-2000, corresponding to the historical group; and 2005-2010, corresponding to the intervention group. New therapeutic procedures were implemented during the period 2005-2010. These procedures included a sepsis management bundle derived from the Surviving Sepsis Campaign, use of a third-generation cephalosporin and levofloxacin as the initial empirical antimicrobial regimen, and noninvasive mechanical ventilation following extubation. RESULTS: A total of 317 patients were studied: 142 (44.8%) during the historical period and 175 (55.2%) during the intervention period. Sequential Organ Failure Assessment scores were higher in patients in the intervention group (7.2 ± 3.7 vs 6.2 ± 2.8; p=0.008). Mortality changed significantly between the two studied periods, decreasing from 43.6% in the historical group to 30.9% in the intervention group (p < 0.02). A restrictive transfusion strategy, use of systematic postextubation noninvasive mechanical ventilation in patients with severe chronic respiratory or cardiac failure patients, less frequent use of dobutamine and/or epinephrine in patients with sepsis or septic shock, and delivery of a third-generation cephalosporin associated with levofloxacin as empirical antimicrobial therapy were independently associated with better outcomes. CONCLUSION: Positive outcomes in ICU patients with CAP have significantly increased in our ICU in recent years. Many new interventions have contributed to this improvement.

ABSTRACT

INTRODUCTION: Since 2017, pre-exposure prophylaxis (PrEP) has been one of the tools in combination HIV prevention strategies. The objective of our questionnaire was to analyze the knowledge and the position of general practitioners in Hauts-de-France on PrEP. METHOD: This quantitative, observational, cross-sectional study was conducted in 2020 using an anonymous questionnaire sent by post to a sample of 3007 GPs. RESULTS: Four hundred and forty-four questionnaires (14.8 %) were included. The GPs were predominantly male (n = 253, 57 %) with a median age of 47 years. The median interest shown by respondents was 7/10. One hundred and sixty participating GPs (36%) were aware of the principles of PrEP, one hundred and sixty were only aware of the title (36%) and 124 (28%) showed no awareness at all. Out of the 160 GPs who knew about PrEP, 72 % considered it effective, 30 % knew about it from a patient and 34 % declared having at least one patient using PrEP. GPs who knew about PrEP were more likely to: have graduated less than 10 years before, having seen in consultation men who have sex with men (MSMs) and, lastly; using screening practices for sexually transmitted infections that were better aligned with the recommendations than those who reported not knowing about PrEP. CONCLUSION: Although PrEP remains insufficiently known to GPs, many expressed eagerness to be involved. The training of health professionals and the highlighting of GPs' role in prevention could help to optimize the fight against HIV.

ABSTRACT

National and international guidelines were recently published regarding the treatment of Enterobacteriaceae resistant to third-generation cephalosporins infections. We aimed to assess the implementation of the French guidelines in critically ill patients suffering from extended-spectrum ß-lactamase-producing Enterobacteriaceae bloodstream infection (ESBL-E BSI). We conducted a retrospective observational cohort study in the ICU of three French hospitals. Patients treated between 2018 and 2022 for ESBL-E BSI were included. The primary assessment criterion was the proportion of adequate empirical carbapenem prescriptions, defined as prescriptions consistent with the French guidelines. Among the 185 included patients, 175 received an empirical anti-biotherapy within 24 h of ESBL-E BSI onset, with a carbapenem for 100 of them. The proportion of carbapenem prescriptions consistent with the guidelines was 81%. Inconsistent prescriptions were due to a lack of prescriptions of a carbapenem, while it was recommended in 25% of cases. The only factor independently associated with adequate empirical carbapenem prescription was ESBL-E colonization (OR: 107.921 [9.303-1251.910], p = 0.0002). The initial empirical anti-biotherapy was found to be appropriate in 83/98 patients (85%) receiving anti-biotherapy in line with the guidelines and in 56/77 (73%) patients receiving inadequate anti-biotherapy (p = 0.06). Our results illustrate the willingness of intensivists to spare carbapenems. Promoting implementation of the guidelines could improve the proportion of initial appropriate anti-biotherapy in critically ill patients with ESBL-E BSI.

ABSTRACT

Pulmonary multiplex polymerase chain reaction (m-PCR) allows rapid pathogen detection. We aimed to assess its impact on initial antibiotic prescriptions in ventilated patients with suspected pneumonia. Between November 2020 and March 2022,ventilated patients with suspected pneumonia hospitalized in our ICU who benefited from respiratory sampling simultaneously tested using conventional microbiological methods and m-PCR were included. The proportion of appropriate changes in the initial antibiotic therapy following m-PCR results was assessed. We analyzed 104 clinical samples. Of the 47 negative m-PCR results, 16 (34%) led to an appropriate antibiotic strategy: 8 cessationsand 8 lack of initiation. Of the 57 positive m-PCR results, 51 (89%) resulted in an appropriate antibiotic strategy: 33 initiations, 2 optimizations, and 9 de-escalations. In the multivariate analysis, a positive m-PCR was associated with an appropriate antibiotic change (OR: 96.60; IC95% [9.72; 960.20], p < 0.001). A higher SAPS II score was negatively associated with an appropriate antibiotic change (OR: 0.96; IC95% [0.931; 0.997], p = 0.034). In our cohort, a positive m-PCR allowed for early initiation or adjustment of antibiotic therapy in almost 90% of cases. A negative m-PCR spared antibiotic use in onethird of cases. The impact of m-PCR results was reduced in the most severe patients.

ABSTRACT

PURPOSE OF REVIEW: This review provides a focus on infections of prosthetic vascular grafts used to treat peripheral arterial diseases. RECENT FINDINGS: The incidence of infections varies between 1 and 6%. Risk factors of infection are not well identified. Main causative pathogens are Gram-negative bacilli, Staphylococcus aureus, and coagulase-negative staphylococci, without clear differences according to location of graft and time of onset of infection. There is no consensual diagnostic criterion. The basic principles for management of graft infections have been known for many years. A surgical approach combining graft excision, complete debridement, and maintaining distal vascular flow is required. Antimicrobial therapy is always instituted to reduce sepsis and prevent secondary graft infection, but there are no evidence-based data to recommend any regimen. However, antibiotics should have bactericidal activity whatever the bacteria growth phase, reduce the microbial burden, penetrate within the biofilm, and prevent further biofilm formation. Mortality and morbidity from these infections remain significant. SUMMARY: A multidisciplinary approach with a limited number of reference centres, recruiting sufficient numbers of patients to perform controlled trials, and to provide expert recommendations, could be the best way to answer unresolved questions and improve the prognosis.

ABSTRACT

We report the first case of extended-spectrum beta-lactamase producing E. coli community-acquired meningitis complicated with multiple aortic mycotic aneurysms. Because of the acute aneurysm expansion with possible impending rupture on 2 abdominal CT scan, the patient underwent prompt vascular surgery and broad spectrum antibiotic therapy but he died of a hemorrhagic shock. Extended-spectrum beta-lactamase producing E. coli was identified from both blood and cerebrospinal fluid culture before vascular treatment. The present case report does not however change the guidelines of Gram negative bacteria meningitis in adults.

ABSTRACT

BACKGROUND: The impact of highly active antiretroviral therapy (HAART) in HIV-infected patients admitted to the intensive care unit (ICU) remains controversial. We evaluate impact of HAART prescription in HIV-infected patients admitted to the ICU of Tourcoing Hospital from January 2000 to December 2009. RESULTS: There were 91 admissions concerning 85 HIV-infected patients. Reasons for ICU admission were an AIDS-related diagnosis in 46 cases (51%). Fifty two patients (57%) were on HAART at the time of ICU admission, leading to 21 immunovirologic successes (23%). During the ICU stay, HAART was continued in 29 patients (32%), and started in 3 patients (3%). Only one patient experienced an adverse event related to HAART. Mortality rate in ICU and 6 months after ICU admission were respectively 19% and 27%. Kaplan-Meier estimates of the cumulative unajusted survival probability over 6 months were higher in patients treated with HAART during the ICU stay (Log rank: p = 0.04). No benefit of HAART in ICU was seen in the adjusted survival proportion at 6 months or during ICU stay. Prescription of HAART during ICU was associated with a trend to lower incidence of new AIDS-related events at 6 months (respectively 17% and 34% with and without HAART, p = 0.07), and with higher incidence of antiretroviral resistance after ICU stay (respectively 25% and 7% with and without HAART, p = 0.02). CONCLUSIONS: Our results suggest a lower death rate over 6 months in critically ill HIV-infected patients taking HAART during ICU stay. The optimal time to prescribe HAART in critically ill patients needs to be better defined.

ABSTRACT

BACKGROUND: Patients living with HIV (PLWHIV) can develop autoimmune diseases (AD) needing immunosuppressive treatments (IST). This study aims to describe the impact of IST in PLWHIV. METHODS: This was a multicentric retrospective observational study in six HIV referral centers on PLWHIV under IST for AD. Demographic factors, viral co-infections, immunovirological status before and under IST, infectious events, and their descriptions were collected and described focusing on infectious events, immunovirological variations, and IST effectiveness. RESULTS: 9480 PLWHIV were screened for inclusion. Among them, 138 (1.5%) had a history of auto-immune disease, among which 32 (23%) received IST. There was mainly spondyloarthropathy (28%) and the most commonly used IST was methotrexate. The median follow-up under IST was 3.8 years (2.7; 5.9). There were 15 infectious events (0.5 events/individuals) concerning nine patients. At the last medical follow-up, 81% of these were in remission of their AD. Under IST, there was an increase in CD4 during follow-up (629 vs. 827 CD4/mm3, p = 0.04). No HIV virological failure was noted. CONCLUSIONS: This study supports a growing evidence base that IST can be used safely and effectively in PLWHIV with careful monitoring.
