Abstract
BACKGROUND The new definitions of antimicrobial susceptibility categories proposed by EUCAST in 2020 require the definition of standard and high dosages of antibiotic. For injectable β-lactams, standard and high dosages have been proposed for short-infusion regimens only. OBJECTIVES To evaluate dosages for β-lactams administered by prolonged infusion (PI) and continuous infusion (CI). METHODS Monte Carlo simulations were performed for seven injectable β-lactams: aztreonam, cefepime, cefotaxime, cefoxitin, ceftazidime, piperacillin and temocillin. Various dosage regimens based on short infusion, PI or CI were simulated in virtual patients. Pharmacokinetic (PK) profiles and PTAs were obtained based on reference population PK models, as well as PK/pharmacodynamic targets and MIC breakpoints proposed by EUCAST. Alternative dosage regimens associated with PTA values similar to those of recommended dosages up to the breakpoints were considered acceptable. RESULTS Adequate PTAs were confirmed for most EUCAST short-infusion dosage regimens. A total of 9 standard and 14 high dosages based on PI (3 to 4 h) or CI were identified as alternatives. For cefepime and aztreonam, only PI and CI regimens could achieve acceptable PTAs for infections caused by Pseudomonas spp.: 2 g q8h as PI of 4 h or 6 g/24 h CI for cefepime; 2 g q6h as PI of 3 h or 6 g/24 h CI for aztreonam. CONCLUSIONS These alternative standard and high dosage regimens are expected to provide antibiotic exposure compatible with new EUCAST definitions of susceptibility categories and associated MIC breakpoints. However, further clinical evaluation is necessary.

Abstract
LYME BORRELIOSIS. Lyme borreliosis (LB) is the most common vector-borne disease in the Northern Hemisphere, caused by the bacterium Borrelia burgdorferi sensu lato, transmitted to humans by a bite of ticks Ixodes. Prevention is based on simple measures to evict ticks, and on their rapid extractionin the event of a bite. The diagnosis of LB is based on 3 arguments: an exposure to tick bites; clinically compatible symptoms (cutaneous, neurological or rheumatological manifestations, +/- functional symptoms such as fatigue or polyarthromyalgia), evolving in 3 stages (early localized or erythema migrans, early or late disseminated LB); a positive two-tier serological test (ELISA +/- Western-Blot). Serology can be negative for the first 6 weeks, without excluding the diagnosis. Since serology can remain positive for life, evolution is only evaluated clinically. LB treatment is mainly based on doxycycline for 14 to 28 days, depending on the clinical stage and manifestations, without demonstrated interest in prolonging it, even if symptoms persist. Nonetheless their management is crucial as often responsible for medical wandering. Attentive listening to the patient is essential. The prognosis of LB in the medium-term is favorable, especially if they beneficiate of an early management.

Abstract
OBJECTIVES Isoniazid-monoresistant tuberculosis (HR-TB) is the most prevalent form of drug-resistant TB worldwide and in France and is associated with poorer treatment outcomes compared with drug-susceptible TB (DS-TB). The objective of this study was to determine the characteristics of HR-TB patients in France and to compare outcomes and safety of treatment for HR-TB and DS-TB. METHODS We performed a case-control multicenter study to identify risk factors associated with HR-TB and compare treatment outcomes and safety between HR-TB patients and DS-TB patients. RESULTS Characteristics of 99 HR-TB patients diagnosed and treated in the university hospitals of Paris, Lille, Caen and Strasbourg were compared with 99 DS-TB patients. Female sex (OR = 2.2; 1.0-4.7), birth in the West-Pacific World Health Organization region (OR = 4.6; 1.1-18.7) and resistance to streptomycin (OR = 77.5; 10.1-594.4) were found to be independently associated with HR-TB. Rates of treatment success did not differ significantly between HR-TB and DS-TB. CONCLUSIONS Factors associated with HR-TB are not significant enough to efficiently screen TB patients at risk of HR-TB. The systematic implementation of rapid molecular testing on clinical samples remains the only effective way to make the early diagnosis of HR-TB and adapt treatment.

Abstract
Background PCRs targeting 16S ribosomal DNA (16S PCR) followed by Sanger’s sequencing can identify bacteria from normally sterile sites and complement standard analyzes, but they are expensive. We conducted a retrospective study in the Strasbourg University Hospital to assess the clinical impact of 16S PCR sequencing on patients’ treatments according to different sample types. Methods From 2014 to 2018, 806 16S PCR samples were processed, and 191 of those were positive. Results Overall, the test impacted the treatment of 62 of the 191 patients (32%). The antibiotic treatment was rationalized in 31 patients (50%) and extended in 24 patients (39%), and an invasive procedure was chosen for 7 patients (11%) due to the 16S PCR sequencing results. Positive 16S PCR sequencing results on cerebrospinal fluid (CSF) had a greater impact on patients’ management than positive ones on cardiac valves (p = 0.044). The clinical impact of positive 16S PCR sequencing results were significantly higher when blood cultures were negative (p < 0.001), and this difference appeared larger when both blood and sample cultures were negative (p < 0.001). The diagnostic contribution of 16S PCR was higher in patients with previous antibiotic treatment (p < 0.001). Conclusion In all, 16S PCR analysis has a significant clinical impact on patient management, particularly for suspected CSF infections, for patients with culture-negative samples and for those with previous antibiotic treatments.

Abstract
BACKGROUND Lyme borreliosis in humans results in a range of clinical manifestations, thought to be partly due to differences in the pathogenicity of the infecting strain. This study compared European human clinical strains of Borreliella afzelii (previously named Borrelia afzelii) using multilocus sequence typing (MLST) to determine their spatial distribution across Europe and to establish whether there are associations between B. afzelii genotypes and specific clinical manifestations of Lyme borreliosis. For this purpose, typing was performed on 63 strains, and data on a further 245 strains were accessed from the literature. RESULTS All 308 strains were categorized into 149 sequence types (STs), 27 of which are described here for the first time. Phylogenetic and goeBURST analyses showed short evolutionary distances between strains. Although the main STs differed among the countries with the largest number of strains of interest (Germany, the Netherlands, France and Slovenia), the B. afzelii clinical strains were less genetically structured than those previously observed in the European tick population. Two STs were found significantly more frequently in strains associated with clinical manifestations involving erythema migrans, whereas another ST was found significantly more frequently in strains associated with disseminated manifestations, especially neuroborreliosis. CONCLUSIONS The MLST profiles showed low genetic differentiation between B. afzelii strains isolated from patients with Lyme borreliosis in Europe. Also, clinical data analysis suggests the existence of lineages with differential dissemination properties in humans.

Abstract
Objectives We investigated the epidemiological, clinical, microbiological and genetic characteristics of linezolid-resistant (LZR) Staphylococcus capitis isolates from French ICUs, and compared them with LZR S. capitis isolates from other European countries. Methods All LZR isolates were subjected to antimicrobial susceptibility testing (AST) and the presence of cfr and optrA genes as well as mutations in the 23S rRNA and ribosomal proteins were investigated using specific PCR with sequencing. The genetic relationship between isolates was investigated using PFGE and WGS. Epidemiological data concerning LZR S. capitis were collected retrospectively in French microbiology laboratories. Results Twenty-one LZR isolates were studied: 9 from France, 11 from Greece and 1 from Finland. All were resistant to methicillin and aminoglycosides. In addition, this unusual AST profile was identified in S. capitis isolates from seven French hospitals, and represented up to 12% of the S. capitis isolates in one centre. A G2576T mutation in 23S rRNA was identified in all isolates; cfr and optrA genes were absent. All isolates belonged to the same clone on the basis of their PFGE profiles, whatever their geographical origin. WGS found at most 212 SNPs between core genomes of the LZR isolates. Conclusions We identified and characterized an LZR S. capitis clone disseminated in three European countries, harbouring the same multiple resistance and a G2576T mutation in the 23S rRNA. The possible unrecognized wider distribution of this clone, belonging to a species classically regarded as a low-virulence skin colonizer, is of major concern not least because of the increasing use of oxazolidinones.

Abstract
INTRODUCTION Few studies have evaluated the promising role of 18F-fluoro-2-deoxy-D-glucose positron emission tomography (PET) and PET/computed tomography FDG PET/CT in evaluating and monitoring treatment response in patients with lymph node tuberculosis (LNTB). The aim of this clinical investigation was to assess the clinical usefulness of FDG PET/CT for initial tuberculosis staging and to determine the prognostic value of the decrease of 18F-FDG uptake during antibiotic treatment in LNTB patients. METHODS We retrospectively reviewed 18 cases of LNTB admitted at a single center from 2004 to 2014. Medical records of patients who underwent two FDG PET/CT (>6 months interval), at initial staging and at the end of therapy were reviewed to determine the impact of FDG PET/CT on initial management of LNTB and response to therapy. Statistical analysis was performed using linear mixed-effects model. RESULTS Thirteen cases of disseminated LNTB and five cases of localized LNTB were included in the study. Initial FDG PET/CT allowed guided biopsy for initial diagnosis in 5 patients and identified unknown extra-LN TB sites in 9 patients. Visual analysis follow-up of FDG PET/CT showed a complete metabolic response in 9/18 patients (all of whom were cured), a partial response in 7/18 (5 of whom were cured) and no response in 2/18 (all of whom were not cured). The semi-quantitative evaluation of 18F-FDG intensity decrease based on the maximum standardized uptake value (SUVmax), compared to targeted estimated decrease allowed to predict correctly a complete response to treatment in 14/18 cases. CONCLUSION FDG PET/CT allows an accurate pre-therapeutic mapping of LNTB and helps for early TB confirmation. The SUVmax follow up is a potential tool for monitoring the treatment response.

Abstract
In Lyme borreliosis, the skin is the key site for bacterial inoculation by the infected tick and for cutaneous manifestations. We previously showed that different strains of Borrelia burgdorferi sensu stricto isolated from tick and from different clinical stages of the Lyme borreliosis (erythema migrans, and acrodermatitis chronica atrophicans) elicited a very similar transcriptional response in normal human dermal fibroblasts. In this study, using whole transcriptome microarray chips, we aimed to compare the transcriptional response of normal human dermal fibroblasts stimulated by 3 Borrelia burgdorferi sensu lato strains belonging to 3 main pathogenic species (B. afzelii, B. garinii and B. burgdorferi sensu stricto) in order to determine whether “species-related” inflammatory pathways could be identified. The three Borrelia strains tested exhibited similar transcriptional profiles, and no species-specific fingerprint of transcriptional changes in fibroblasts was observed. Conversely, a common core of chemokines/cytokines (CCL2, CXCL1, CXCL2, CXCL6, CXCL10, IL-6, IL-8) and interferon-related genes was stimulated by all the 3 strains. Dermal fibroblasts appear to play a key role in the cutaneous infection with Borrelia, inducing a homogeneous inflammatory response, whichever Borrelia species was involved.

Abstract
The aim of this study was to compare the in vitro susceptibility of Klebsiella pneumoniae, Pseudomonas aeruginosa and Stenotrophomonas maltophilia to three fluoroquinolones. The minimum inhibitory concentrations (MICs) to ciprofloxacin, levofloxacin and moxifloxacin were examined by E-test® for a total of 40 K. pneumoniae strains, 40 S. maltophilia strains and 40 P. aeruginosa strains. Then, the bactericidal activity of these fluoroquinolones was investigated on five strains of each bacterial species by means of time-kill curves. For K. pneumoniae and P. aeruginosa, the distance of the measured MIC from the clinical break-point is a good indicator of the bactericidal activity for ciprofloxacin and levofloxacin as obtained in our experiments. The lower the MIC, the better the bactericidal activity in term of CFU Log decreases. If MIC of ciprofloxacin and levofloxacin against the considered bacteria are far from clinical breakpoint, these two antibiotics are equivalent. According to our MIC50 and modal MIC, the breakpoints of both ciprofloxacin and levofloxacin seem to be somewhat high and data suggest reducing them. On S. maltophilia, none of the tested antibiotics showed a satisfactory activity.

Abstract
Broad range PCR targeting the 16S rRNA gene is widely used to test clinical samples for the presence of bacterial DNA. End-point 16S PCR is both time-consuming and at high risk of cross-contamination. Prior to the replacement of the 16S end-point PCR assay routinely used in our clinical laboratory by a new 16S real-time PCR assay, we aimed to compare the performances of both techniques for the direct diagnosis of bacterial infections in clinical samples. In this prospective study, 129 clinical samples were included for direct comparison of both techniques. The sensitivity of 16S real-time PCR assay (76%) was significantly higher than that of end-point 16S PCR assay (41%) (p<0.01). Specificities of both PCR assays did not differ significantly (p=0.43). The 16S real-time PCR assay yielded an etiological diagnosis in 19% of culture-negative samples. It constitutes a reliable and complementary diagnostic tool to the bacterial culture.

Abstract
The hard tick Ixodes uriae parasitises a wide range of seabird species in the circumpolar areas of both Northern and Southern hemispheres and has been shown to be infected with Borrelia burgdorferi sensu lato, the bacterial agents of Lyme borreliosis. Although it is assumed that seabirds represent viable reservoir hosts, direct demonstrations of infection are limited to a single study from the Northern hemisphere. Here, the blood of 50 tick-infested adult king penguins (Aptenodytes patagonicus halli) breeding in the Crozet Archipelago (Southern Indian Ocean) was examined for B. burgdorferi sl exposure by serology and for spirochetemia by in vitro DNA amplification. Four birds were found positive by serology, whereas B. burgdorferi sl DNA was detected in two other birds. Our data therefore provide the first direct proof of Borrelia burgdorferi sl spirochetes in seabirds of the Southern hemisphere and indicate a possible reservoir role for king penguins in the natural maintenance of this bacterium. Although the bacterial genetic diversity present in these hosts and the infectious period for tick vectors remain to be elucidated, our results add to a growing body of knowledge on the contribution of seabirds to the complex epizootiology of Lyme disease and the global dissemination of B. burgdorferi sl spirochetes.

Abstract
ZusammenfassungVor dem Hintergrund einer Neugestaltung des Eltern-Kind-Vorsorgeprogramms in Österreich, welche auch eine elektronische statt papierbasierte Umsetzung beinhalten könnte, soll ein Überblick internationaler Pilotierungen elektronischer Eltern-Kind-Vorsorge Initiativen (eEKVI) gegeben, und für die Umsetzung relevanten Grenzen, Möglichkeiten und Zielsetzungen dieser Projekte aufgezeigt werden.Datenbankrecherche sowie Handsuche nach internationalen (Pilot-) Projekten.Von 30 ausgewählten eEKVI können 9 als elektronische Eltern- bzw. Kinder-Gesundheitsakten angesehen werden, welche entweder im Kontext einer umfassenden elektronischen Gesundheitsakte, als elektronische Umsetzung eines papierbasierten Dokuments oder als an eine Einrichtung gebundene IT-Lösung realisiert wurden. eEKVI sind bislang international noch kaum flächendeckend implementiert, einige wenige bedienen neben klassischen Kern-Zielen (Abwicklung und Administration der Versorgung usw.) auch planerische Zielsetzungen und ermöglichen dadurch ein systemisches Lernen aufgrund von Feedback und Evaluationszyklen.Basierend auf Erfahrungen internationaler eEKVI sollten Kernaspekte einer erfolgreichen Planung und Umsetzung, wie beispielsweise die Definition von erwarteten Nutzen-Zielen und deren Monitoring oder die Bildung eines für Planung und Konzeption verantwortlichen Teams unter früher Einbeziehung von Endnutzern und Akteuren, berücksichtigt werden, um vermeidbare Fehler zu minimieren. Eine konsequente Technikfolgenabschätzung – auch von IT-basierten Interventionen im Gesundheitswesen – ist jedenfalls zu fordern, um ein reflektiertes Vorgehen zu ermöglichen.

Abstract
OBJECTIVE To describe a relapse of Whipple disease revealed by isolated limbic encephalitis with no other signs of systemic involvement. DESIGN Case report. SETTING University Hospital of Strasbourg, Strasbourg, France. Patient A 41-year-old patient. MAIN OUTCOME MEASURES Cognitive functions and results of cerebrospinal fluid analysis and brain magnetic resonance imaging. RESULTS A 41-year-old patient was hospitalized for headache associated with anterograde amnesia and temporospatial disorientation. Whipple disease with systemic manifestations was diagnosed 4 years previously and insufficiently treated. The neuropsychological evaluation showed impaired episodic memory and executive functions. Analysis of the cerebrospinal fluid showed increased lymphocytes and a positive Tropheryma whipplei polymerase chain reaction result. Cerebral magnetic resonance imaging revealed a typical pattern of limbic encephalitis with an intense signal in the amygdalae and hippocampi. The outcome under antibiotic treatment was marked by partial improvement of the cognitive disorders, disappearance of the positive T whipplei polymerase chain reaction result in cerebrospinal fluid, and a clear decrease of inflammation on brain magnetic resonance imaging. CONCLUSIONS Whipple disease can present as limbic encephalitis. Few cases have been previously described in the literature. Such diagnosis is of importance because of the specific treatment.

Abstract
BACKGROUND Nonrandom distribution of hepatitis C virus (HCV) quasispecies (compartmentalization between blood plasma and leukocytes) suggests the presence of HCV leukotropic variants. HCV compartmentalization in the setting of liver transplantation (LT) is poorly understood. To study HCV leukotropic variants, we investigated the evolution of HCV compartmentalization after immunosuppression in liver transplant recipients. METHODS Plasma and peripheral blood mononuclear cell (PBMC) samples were collected from 5 liver transplant recipients before and after LT. We used clone sequencing to analyze the hypervariable region 1 (HVR1)-E2(384-419) region, which plays a key role in HCV entry and the induction of neutralizing responses, and assessed compartmentalization through phylogenetic analyses and Mantel's test. RESULTS Compartmentalization was frequent in the LT setting. HCV quasispecies were more homogeneous after LT in both the plasma and PBMC compartments, with a significant decrease in quasispecies complexity (P = .003) and genetic distances (P = .004) after transplantation. Our analysis identified 8 PBMC-related amino acid residues in HVR1. CONCLUSIONS HCV compartmentalization between plasma and PBMCs and the emergence of leukotropic variants could be potentiated by immunosuppression in liver transplant recipients. The identification of defined leukotropic variants may contribute to the understanding of virus-host interactions after transplantation.

Abstract
Besides hepatocytes, representing the main replication site of hepatitis C virus, peripheral blood mononuclear cells also represent a crucial target for viral infection. Hepatitis C virus compartmentalization (i.e., non-random distribution) of viral variants between plasma and peripheral blood mononuclear cells, more frequently observed in liver transplant patients compared to non-transplanted patients, makes liver transplantation an interesting model for the analysis of hepatitis C leukotropism. This article aims to present, firstly, in clinical and biological features arguing favour of hepatitis C virus infection leukotropism and, secondly, to review current knowledge about compartmentalization between plasma and peripheral blood mononuclear cells, especially in the liver transplantation setting.

Abstract
Short-term studies have shown that histamine is involved, via its H2 receptors (H2R), in the mediator network regulating trabecular bone loss in long bones of ovariectomized (OVX) rats. It is not known whether this effect of histamine persists over time or involves other skeletal sites. In this study, rats were maintained for 6 months postOVX and treated daily with saline or famotidine (10 mg kg(-1)), an H2R antagonist. At the end of the experimental period, femur trabecular bone mass was markedly decreased in OVX rats, whether or not they were treated with famotidine. In contrast, in the fourth lumbar vertebra, where bone loss starts later than in the femur, famotidine treatment attenuated the decline in trabecular bone volume, protected the trabecular architecture, maintained the thickness of the cortices and reduced the numbers of osteoclasts and tartrate-resistant acid phosphatase-positive preosteoclasts, whereas it had no influence on bone formation parameters. In vertebral bone marrow of OVX rats, the numbers of mast cells (MCs) and non-MC histamine-producing cells increased, while famotidine treatment significantly diminished both cell populations. These data show that H2R antagonism does not protect trabecular bone mass in the long term, and that short-term protection involves all bones. Histamine is involved during the early phase of strong osteoclastic resorption but not during the late phase of slower resorption, suggesting that different mediator networks control the two phases of destruction. Histamine would be part of the network mediating the early phase.

Abstract
Regulations of Integrated Health Care are capable of overriding the barriers of separated outpatient and inpatient health care. These regulations create a situation of competition among health care providers, but not among payers. Since the laws exclude common regulations of competition laws, antitrust laws and public procurement laws from Integrated Health Care, insurance companies gain a relatively strong position in the competition for contracts. This is even enforced by the fact that no health care provider is entitled to request a contract with a specific insurance company. The main result is that insurance companies can determine the contracts deliberately.
