RESUMEN

Herpes zoster is a painful dermatomal cutaneous eruption resulting from reactivation of the latent varicella-zoster virus. Patients with inflammatory bowel diseases have an increased risk of shingles compared with the general population and this risk can be increased with the use of immunosuppressive therapy. Live zoster vaccine and recombinant zoster vaccine have shown efficacy for the prevention of herpes zoster. The recombinant zoster vaccine seems to offer greater efficacy and long-term protection profile compared with the life zoster vaccine. However, their use in clinical practice still is unclear and updated vaccination recommendations are lacking. This review discusses the risk for shingles in patients with inflammatory bowel diseases, available vaccines, and their efficacy and safety profiles. We also provide guidance on who, when, and how to vaccinate for herpes zoster in routine clinical practice among patients with inflammatory bowel diseases.

RESUMEN

BACKGROUND AND AIMS: Inflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), and human immunodeficiency virus (HIV) both impact innate and adaptive immunity in the intestinal mucosa. As it is a rare situation, the intersection between HIV and IBD remains unclear, especially the impact of HIV infection on the course of IBD, and the drug safety profile is unknown. METHODS: We conducted a multicenter retrospective cohort study between January 2019 and August 2020. All adult patients with IBD and concomitant HIV infection were included. Each IBD patient with HIV was matched to two HIV-uninfected IBD patients. RESULTS: Overall, 195 patients with IBD were included, including 65 HIV-infected patients and 130 without HIV infection. Of the 65 infected patients, 22 (33.8%) required immunosuppressants and 31 (47.7%) biologics. In the HIV-infected group, the need for immunosuppressants (p = 0.034 for CD and p = 0.012 for UC) and biologics (p = 0.004 for CD and p = 0.008 for UC) was significantly lower. The disease course, using a severity composite criterion, was not significantly different between the two groups for CD (hazard ration (HR) = 1.3 [0.7; 2.4], p = 0.45) and UC (HR, 1.1 [0.5; 2.7], p = 0.767). The overall drug safety profile was statistically similar between the two groups. CONCLUSION: Although HIV-infected patients receive less treatments, the course of their IBD did not differ than uninfected, suggesting that HIV infection might attenuate IBD. The drug safety profile is reassuring, allowing physician to treat these patients according to current recommendations.

RESUMEN

Despite group A streptococci being an infrequent cause of pharyngitis in adult outpatients, sore throat remains a common indication for antibiotic prescription. This prospective multicentre non-randomised study describes a community pharmacy-based antimicrobial stewardship intervention consisting in the implementation of rapid antigen testing (RAT) for the management of adults with sore throat. Trained pharmacists triaged patients presenting with symptoms of pharyngitis using the modified Centor score. Those at risk for streptococcal infection were tested with RAT. Patients with a positive RAT were invited to consult a physician, whereas others were offered a symptomatic treatment. All patients received educational leaflets and were asked to fill in a follow-up form 7 days later. Ninety-eight pharmacies in one French region participated, and 559 patients were included over 6 months. RAT was proposed in 367 (65.7%) cases, and it was positive in 28 (8.3%). The follow-up form was returned by 140 (38.5%) participants. Of these, 10/10 patients with positive RAT further consulted a physician and were prescribed an antibiotic treatment, whereas 96.5% (110/114) of patients with negative results and not having any other reason to seek for doctor's advice did not consult. All participants found the intervention useful. Pharmacists spent 6-15 min to perform the intervention, and 98.6% (73/74) of pharmacists giving a feedback declared to be ready to implement this intervention in daily practice, if endorsed and reimbursed. Our results suggest that a pharmacy-based programme for the management of sore throat is feasible and could increase adherence to guidelines.

RESUMEN

Occupational blood and body fluids exposure. Occupational blood and body fluids exposure (BBFE) is a serious daily risk to healthcare workers (HCW) wherever they work (i.e. hospital, nursing home or private care). The knowledge of BBFE epidemiology over these 3 sectors of care allows HCF to be aware of BBFE circumstances and can enhance prevention in order to improve overall BBFE prevention. The improvement for compliance with standard precautions and protocols to prevent exposure to BBFE and the increase of safety device disposal use are the main keys of HCW safety.


Accidents exposant au sang en france Les professionnels de santé, quel que soit leur lieu d'activité (hôpital, établissement médico-social et ville), sont, au quotidien, susceptibles d'être victimes d'accidents exposant au sang. La connaissance des données épidémiologiques de ces accidents dans les trois secteurs de l'offre de soins permet aux professionnels de santé d'être conscients des circonstances de ces accidents pour mettre en place les mesures de prévention ad hoc. L'amélioration du respecter des précautions standard et des protocoles pour prévenir l'exposition au sang et aux liquides biologiques ainsi que la mise à disposition croissante des dispositifs médicaux de sécurité sont les principales clefs de la sécurité d'exercice des professionnels.

RESUMEN

This study's objective was to explore the factors associated with the belief (or not) by people living with HIV that it is easier to talk about their seropositivity 10 years after initiating a protease inhibitor-containing ART. All patients in the ANRS CO8 APROCO-COPILOTE cohort who completed a self-administered questionnaire at 10 years of follow-up were included in this study. Forty-four percent of patients declared that discussing their seropositivity with their family was easier 10 years later, while 28 % declared this was true for discussing their status with a new sexual partner. Having a low socioeconomic status, not receiving social support from a steady partner and declaring a low number of discomforting symptoms 12 months after PI initiation were all independently associated with less difficulty in discussing seropositivity. This study highlights the difficulties in disclosing HIV 10 years after PI initiation, and the important influence of psychosocial factors and patients' daily-life experience on disclosure.

RESUMEN

BACKGROUND: Recent studies have shown a decrease in the incidence of herpes zoster (HZ) among human immunodeficiency virus (HIV)-infected patients since the combined antiretroviral therapy (cART) era, but more data are needed on a possible increase in the risk early after cART initiation. METHODS: We studied HZ incidence and risk factors among patients followed in the French Hospital Database on HIV (FHDH) between 1992 and 2011. Standardized incidence ratios (SIRs) were used for comparison with the general population between 2005 and 2008. The risk of HZ following cART initiation (0-5 and ≥6 months) was studied with Poisson regression models. RESULTS: A total of 7167 cases of incident HZ were diagnosed among 91 044 individuals (583 125 person-years [PY]). The incidence declined significantly, from 2955 per 100 000 PY in 1992-1996 to 628 per 100 000 PY in 2009-2011. This decline was mainly explained by cART (relative risk [RR], 0.60; 95% confidence interval {CI}, .57-.64). The risk of HZ was associated with low CD4 cell counts, high HIV RNA levels, low CD4/CD8 ratios, and prior AIDS. Compared to the general population, the risk of HZ was higher in HIV-infected patients (overall SIR, 2.7; 95% CI, 2.6-2.9), particularly those aged 15-44 years (SIR, 4-6). In ART-naive patients, a moderate increase in the HZ risk was observed during the first 6 months of cART, with a peak at 3 months (RR, 1.47; 95% CI, 1.26-1.73), a finding that disappeared after adjustment for the current CD4 cell count (RR, 1.03; 95% CI, .81-1.32). CONCLUSIONS: The risk of HZ has declined markedly among HIV-infected patients in the cART era, but remains 3 times higher than in the general population. The risk increases moderately during the first 6 months of cART.

RESUMEN

BACKGROUND: Concerns have recently emerged about the efficacy and the quality of antibacterial generic products approved for use in humans. METHODS: We searched Medline and Embase for original research articles on antibacterial generic products published in English or French before July 2013. RESULTS: We selected 37 original research articles: 15 on ß-lactams, 10 on glycopeptides, and 12 on other antibacterial agents. The majority of articles (73.0%) were published during 2008-2012. Study designs included analytical chemistry (n = 9), in vitro susceptibility studies (n = 14), animal experiments (n = 6, including 5 using the neutropenic mouse thigh infection model), and clinical studies in humans (n = 15). Of the 37 studies, 14 (37.8%) suggested that some generic products may be inferior to the innovator in terms of purity (n = 2), in vitro activity (n = 3), in vivo efficacy in experimental models (n = 4), clinical efficacy (n = 2), taste (n = 2), or compliance and acceptability in children (n = 1). The majority of in vitro studies (78.6%) found no significant difference between generic products and the innovator. Most (5/6) in vivo studies suggesting a difference between generic products and the innovator were performed in an animal model that is not validated for the evaluation of the efficacy of antibacterial agents. The level of evidence was constantly low in clinical studies. CONCLUSIONS: Published data on antibacterial generic products are limited and heterogeneous, thus precluding any attempt to generalize the study results. This systematic review suggests that additional evidence would be needed before considering a revision of the marketing authorization process for antibacterial generic products.

RESUMEN

BACKGROUND: Current recommendations for empirical antimicrobial therapy in spontaneous bacterial peritonitis (SBP) are based on quite old trials. Since microbial epidemiology and the management of patients have changed, whether these recommendations are still appropriate must be confirmed. METHODS: An observational study that exhaustively collected the clinical and biological data associated with positive ascitic fluid cultures was conducted in four French university hospitals in 2010-2011. RESULTS: Two hundred and sixty-eight documented positive cultures were observed in 190 cirrhotic patients (median age 61.5 years, 58.5% Child score C). Of these, 57 were classified as confirmed SBP and 140 as confirmed bacterascites. The predominant flora was Gram-positive cocci, whatever the situation (SBP, bacterascites, nosocomial/health-care related or not). Enteroccocci (27.7% E. faecium) were isolated in 24% of the episodes, and in 48% from patients receiving quinolone prophylaxis. E. coli were susceptible to amoxicillin-clavulanate and to third-generation cephalosporins in 62.5% and 89.5% of cases, respectively. No single antibiotic allowed antimicrobial coverage of more than 60%. Only combinations such as amoxicillin + third-generation cephalosporin or cotrimoxazole allowed coverage close to 75-80% in non-nosocomial episodes. Combinations based on broader spectrum antibiotics should be considered for empirical therapy of nosocomial infections. CONCLUSIONS: Our study confirmed the changing spectrum of pathogens in SBP and bacterascites, and the need for more complex antibiotic strategies than those previously recommended. Our findings also underline the need for new clinical trials conducted in the current epidemiological context.

RESUMEN

BACKGROUND AND AIMS: Advanced therapies for inflammatory bowel disease [IBD] could potentially lead to a state of immunosuppression with an increased risk of opportunistic infections [OIs]. We aimed to provide an update on the incidence of OIs among adult IBD patients in randomized controlled trials [RCTs] of approved biologics and small-molecule drugs [SMDs]. Also, we aimed to describe OI definitions utilized in RCTs, to ultimately propose a standardized definition. METHODS: Electronic databases were searched from January 1, 1990, until April 16, 2022. Our primary outcome was incidence rate of overall OIs among IBD patients exposed and unexposed to biologics or SMDs. We also describe specific OIs reported in included trials, as well as definitions of OIs within studies when provided. RESULTS: Ninety studies were included. The incidence rates of reported OIs were 0.42 and 0.21 per 100 person-years in patients exposed to advanced therapies and placebo, respectively. This was highest for anti-tumour necrosis factors [0.83 per 100 person-years] and Janus kinase inhibitors [0.55 per 100 person-years] and lowest for anti-integrins and ozanimod. On meta-analysis, no increased risk of OIs was observed. None of the studies provided a detailed definition of OIs, or a comprehensive list of infections considered as OIs. CONCLUSION: Different mechanisms of action may have specific OI profiles. In the absence of a uniform definition of OIs, these estimates are less reliable. We propose a definition to be used in future studies to help provide standardized reporting. When using this definition, we saw significant differences in incidence rates of OIs across mechanisms of action.

RESUMEN

OBJECTIVES: This study of fluoroquinolone use was carried out before and after an educational intervention run by Antibiolor, a regional network to all hospitals in the Lorraine region of France. METHODS: The relevance of fluoroquinolone prescription according to regional guidelines was assessed using a standard card filled out by physicians and pharmacists at the voluntarily participating hospitals. A therapeutic index of adequacy was established for each card. The initial survey took place in January 2008, with feedback and proposals for corrective measures in January 2009. The second survey was organized in June 2009. The results of the 2 surveys were compared. RESULTS: Twenty-four hospitals completed a total of 1336 cards in the first survey (S1) and 944 cards in the second (S2). The appropriateness of indications for fluoroquinolone use improved by 57% between the 2 surveys. All the criteria analyzed (choice of drug, dosage, treatment duration) were significantly improved in S2 compared to S1, as was the adequacy index (70% improvement). CONCLUSIONS: In view of the consequences of fluoroquinolone use, many hospitals in Lorraine were keen to participate in this study, confirming its feasibility over a large area. In view of the study results, the book of guidelines was re-examined and republished at the conclusion of S2. Greater adherence to guidelines was noted in S2, demonstrating the benefit of assessing the situation thoroughly before proposing corrective measures and evaluating their impact.

RESUMEN

France remains one of the European countries with the highest antibiotic use. It is a matter of emergency to use less antibiotics and in a more wisely manner, given the current worldwide bacterial resistance crisis. The following points are key in order to better prescribe antibiotics: use of a structured approach when prescribing an antibiotic, use of diagnostic tests when needed, compliance to recommendations, request for specialist advice in complicated cases, education of patients and continuous medical education/assessment of practice for the physicians.

RESUMEN

BACKGROUND: Exposure of healthcare workers (HCW) to SARS-CoV-2 is a public health concern. Not only are HCWs particularly exposed to SARS-CoV-2, but their contamination can also weaken the healthcare system. METHODS: We analyzed exposure of French University Hospital HCWs to SARS-CoV-2 through history of positive RT-PCR test and SARS-CoV-2 seroprevalence. Potential risk factors, such as age, BMI, having children or not, working in a COVID-19 unit, or smoking were explored. RESULTS: From May to June 2020, among the 8960 employees of the University Hospital of Nancy, a serological test was performed in 4696 HCWs. The average (SD) age was 40.4 (11.4) years, and the sample included 3926 women (83.6%). Of the 4696 HCWs, 1050 were smokers (22.4%). Among them, 2231 HCWs had a history of COVID-19 symptoms and/or flu-like syndrome (47.5%) and 238 were seropositive (5.1%). Neither gender, sex, BMI, nor having children were associated with a history of positive RT-PCR test or seropositive status. Previous work in a COVID-19 unit was associated with a history of positive RT-PCR test (p = 0.045), but not with seroprevalence (p = 0.215). As expected, history of COVID-19 clinical manifestations was more frequent in HCWs with positive serology than in HCWs with negative serology (adjusted OR = 1.9, 95%CI [1.4-2.5], p < 0.001). Less expected, smoking was associated with a reduced risk of seropositivity among HCWs (adjusted OR = 0.6, 95%CI [0.4-0.9], p = 0.019). CONCLUSION: HCW are patently exposed to SARS-CoV-2. Care to COVID-19 patients was not associated with a higher SARS-CoV-2 seroprevalence. Smoking appears here associated to a lower seroprevalence.

RESUMEN

OBJECTIVES: To describe the epidemiology of COVID-19 in French professional football players, and to compare the infection incidence with the general population across the first three waves. METHODS: During the 2020-2021 season, all professional football players (n = 1217) in the two primary French leagues underwent weekly testing for SARS-CoV-2 infection by nasopharyngeal PCR, in combination with rigorous infection control measures. RESULTS: Among all players, 572 (47%) tested positive at least once, with no COVID-19-related death or hospital admission. Monthly incidence estimates in players ranged from 1486 to 6731 per 100,000 individuals, i.e. 2-17 times higher than incidence estimates in the general population in France during the study period. CONCLUSION: Almost 50% of professional football players developed SARS-CoV-2 infection during the 2020-2021 season in France, with no severe complication.

RESUMEN

BACKGROUND: Some subjective symptoms may be reported at all stages of Lyme borreliosis (LB) and may persist for several months after treatment. Nonspecific symptoms without any objective manifestation of LB are sometimes attributed by patients to a possible tick bite. The aim of our study was to explore the perceptions, representations, and experiences that these patients had of their disease and care paths. METHODS: We performed a qualitative study through individual interviews (October 2017-May 2018), based on grounded theory, following the COREQ checklist. A balanced sample of patients with diverse profiles was recruited at consultations with general practitioners and infectious disease physicians. RESULTS: Twelve patients were interviewed. Data saturation was reached at the twelfth interview. For codes, 293 were identified, and classified into 5 themes: (1) the experience of disabling nonspecific symptoms, especially pain, causing confusion and fear, (2) long and difficult care paths for the majority of the patients, experienced as an obstacle course, (3) a break with the previous state of health, causing a negative impact on every sphere of the patient's life, (4) empowerment of the patients and the self-management of their disease, and (5) the strong expression of a desire for change, with better listening, greater recognition of the symptoms, and simpler care paths. CONCLUSIONS: This study allows for the understanding of a patient's behaviours and the obstacles encountered, the way they are perceived, and the necessary solutions. The patients' expectations identified here could help physicians better understand the doctor-patient relationship in these complex management situations, which would reduce the burden of the disease. The current development of specialised reference centres could help meet the patients' demands and those of family physicians.

RESUMEN

We investigated the impact of probiotics on the intestinal carriage of vancomycin-resistant enterococci (VRE). Administration of Lactobacillus rhamnosus Lcr35 but not Escherichia coli Nissle reduced, although not significantly, the density of VRE colonization in a murine model. No effect of Lcr35 was observed in a double-blind placebo randomized study, involving nine patients.

RESUMEN

Acetic acid bacteria (AAB) are broadly used in industrial food processing. Among them, members of the genera Asaia, Acetobacter, and Granulibacter were recently reported to be human opportunistic pathogens. We isolated AAB from clinical samples from three patients and describe here the clinical and bacteriological features of these cases. We report for the first time (i) the isolation of a Gluconobacter sp. from human clinical samples; (ii) the successive isolation of different AAB, i.e., an Asaia sp. and two unrelated Gluconobacter spp., from a cystic fibrosis patient; and (iii) persistent colonization of the respiratory tract by a Gluconobacter sp. in this patient. We reviewed the main clinical features associated with AAB isolation identified in the 10 documented reports currently available in the literature. Albeit rare, infections as well as colonization with AAB are increasingly reported in patients with underlying chronic diseases and/or indwelling devices. Clinicians as well as medical microbiologists should be aware of these unusual opportunistic pathogens, which are difficult to detect during standard medical microbiological investigations and which are multiresistant to antimicrobial agents. Molecular methods are required for identification of genera of AAB, but the results may remain inconclusive for identification to the species level.

RESUMEN

The bacterial epidemiology of bacterascites and spontaneous bacterial peritonitis is evolving. Four hundred and eleven strains isolated from ascites in cirrhotic patients from 5 French hospitals were isolated in 2006 and 2007. Of these, 114 were definitely associated with spontaneous bacterial peritonitis. The proportion of Gram-positive and Gram-negative agents was quite similar, even after excluding coagulase-negative staphylococci, or when considering only definite spontaneous bacterial peritonitis or community-acquired strains. Staphylococci and Escherichia coli were the most frequent pathogens, but enterococci were also involved in nearly 15% of the cases. Among the E. coli, 28% were intermediate or resistant to amoxicillin+clavulanate, 5.3% expressed cephalosporinases or extended beta-lactamases and 17.3% were intermediate or resistant to fluoroquinolones. Resistance to methicillin was observed in 27% of Staphylococcus aureus. Cefotaxime and amoxicillin-clavulanate remained the most effective 'single' agents, however on less than 70% of isolates. Some combinations (such as cefotaxime+amoxicillin) extended coverage to a further 15% of strains. Since inadequate empiric antibiotic therapy is associated with increased mortality, these combinations may be of great interest as first-line treatment, even though they may also lead to the development of antimicrobial resistance.
