RESUMO
OBJECTIVES: Suppressive antibiotic therapy (SAT) is a long-term antibiotic strategy at times applied when an indicated surgical management of infective endocarditis (IE) is not possible. Our aim was to describe the characteristics and outcomes of patients having received SAT for IE. METHODS: We conducted a retrospective, observational study at Strasbourg University Hospital, France between January 2020 and May 2023. We reviewed all medical files taken into consideration at weekly meetings of the local Multidisciplinary Endocarditis Team (MET) during the study period. We included patients having received SAT following the MET evaluation. The primary endpoint was all-cause mortality at most recent follow-up. Secondary endpoints included all-cause mortality at 3 and 6 months, infection relapse, and tolerance issues attributed to SAT. RESULTS: The MET considered 251 patients during the study time, among whom 22 (9 %) had received SAT. Mean age was 77.2 ± 12.3 years. Patients were highly comorbid with a mean Charlson index score of 6.6 ± 2.5. Main indication for SAT was surgery indicated but not performed or an infected device not removed (20/22). Fourteen patients had prosthetic valve IE, including 9 TAVIs. Six patients had IE affecting cardiac implantable electronic devices. Staphylococcus aureus and enterococci were the main bacteria involved (6/22 each). Median follow-up time was 249 days (IQR 95-457 days). Mortality at most recent follow-up was 23 % (5/22). Three patients (14 %) presented tolerance issues attributed to SAT, and two patients suffered late infectious relapse. CONCLUSION: Mortality at most recent follow-up was low and tolerance issues were rare for patients under SAT, which might be a palliative approach to consider when optimal surgery or device removal is not possible.

Social science studies on the controversy surrounding Lyme disease (LD) focused on the opposition between the "mainstream" and biomedical approach on one side and the "Lyme-literate" one on the other side, the latter claiming the existence of the chronic form of LD. The qualitative and exploratory study 'C18-48 Quali-Explo-PIQTIQ' (2019) investigated the social representations of LD in patients bitten by a tick. Twenty-four semi-structured interviews were conducted in three French medical units. Thematic and patient trajectory analyses were performed. Our results showed that, after the tick bite, some patients presented an "illness without disease" condition, characterised by uncertainty. In some cases, they consulted "Lyme-literate" health providers and received a diagnosis of chronic LD. This diagnosis was obtained by prescribing unassessed biological testing, providing an objective result and clinical categorisation. Unlike literature on the "Lyme-literate" approach, this diagnostic procedure involved some biomedical operations.

This study aimed to assess the proportion of carbapenemase-producing Enterobacterales (CPE) infections among all infectious episodes in CPE carriers, compare the time-to-onset of CPE infections with that of other infections, assess the mortality of patients with CPE infections, and identify risk factors for CPE infections in CPE carriers. A retrospective cohort study was performed over a 10-year period in our University Hospital, and 274 CPE carriers were identified. All infectious episodes within the first 6 months following the diagnosis of CPE rectal carriage were considered. Risk factor analysis for CPE infections in CPE carriers was performed by univariate and multivariate analyses. This study revealed an incidence of 24.1% (66/274) of CPE infection within 6 months of CPE carriage diagnosis. The 28-day all-cause mortality due to CPE infections was 25.7%. CPE infections represented 52.6% (70/133) of all infectious episodes in CPE carriers in the first 6 months following CPE carriage detection, and these significantly occurred earlier than non-CPE infections, with a median time of 15 versus 51 days, respectively (P < 0.01). Based on the multivariate analysis, prior neurological disease was the only risk factor associated with CPE infections in CPE carriers. CPE infections have an early onset, accounting for a large proportion of infections in CPE carriers, and are associated with high mortality. IMPORTANCE Carbapenemase-producing Enterobacterales (CPE) infections are emerging infections and may represent a therapeutic challenge, while effective antibiotic therapy is likely to be delayed. We aimed to assess the proportion of CPE infections in CPE carriers and to identify risk factors of CPE infections among this population that could guide empirical antibiotic therapy. We showed that CPE infections are frequent in CPE carriers, have an early onset after CPE carriage diagnosis, and represent a significant proportion of all infectious episodes in CPE carriers. No significant risk factors for CPE infections could be identified. Overall, this study suggests that empirical antibiotic treatment covering CPE might be initiated in CPE carriers at least in the first month after its diagnosis and in severe infections due to the high frequency and early occurrence of CPE infections in these patients.

OBJECTIVES: Diagnosis of COVID-19 is essential to prevent the spread of SARS-CoV-2. Nasopharyngeal swabs (NPS) remain the gold standard in screening, although associated with false negative results (up to 30%). We developed a 3D simulator of the nasal and pharyngeal cavities for the learning and improvement of NPS collection. PATIENTS AND METHODS: Simulator training sessions were carried out in 11 centers in France. A questionnaire assessing the simulator was administered at the end of the sessions. The study population included both healthcare workers (HCW) and volunteers from the general population. RESULTS: Out of 589 participants, overall satisfaction was scored 9.0 [8.9-9.1] on a scale of 0 to 10 with excellent results in the 16 evaluation items of each category (HCWs and general population, NPS novices and experienced). The simulator was considered very realistic (95%), easy to use (97%), useful to understand the anatomy (89%) and NPS sampling technique (93%). This educational tool was considered essential (93%). Participants felt their future NPS would be more reliable (72%), less painful (70%), easier to perform (88%) and that they would be carried out more serenely (90%). The mean number of NPS conducted on the simulator to feel at ease was two; technical fluency with the simulator can thus be acquired quickly. CONCLUSION: Our simulator, whose 3D printing can be reproduced freely using a permanent open access link, is an essential educational tool to standardize the learning and improvement of NPS collection. It should enhance virus detection and thus contribute to better pandemic control.

OBJECTIVES: To compare two learning methods for Lyme disease (e-learning versus face-to-face training) to assess knowledge and know-how. METHODS: The study population was volunteer general medicine residents and family physicians (FP). Face-to-face training on Lyme disease was offered to each group. E-learning training was then offered to those who had not attended the face-to-face training. Theoretical knowledge was assessed by an identical pre- and post-test questionnaire and know-how by a script concordance test. RESULTS: Seventy learners (47 FPs and 23 general medicine residents) were included in the face-to-face training group and 61 (33 FPs and 28 general medicine residents) in the e-learning group. The pre- and post-test scores were significantly improved in the FP group (difference of 29.3±1.9 [P<0.0001] out of 100) as well as in the general medicine resident group (difference of 38.2±2.7 [P<0.0001] out of 100). E-learning was more effective than face-to-face training, particularly among general medicine residents (progression of mean difference of 44.3±3.4/100 vs. 30.9±4.0/100; P=0.0138) and to a lesser extent among FPs (progression of 25.3±2.3/100 vs. 31.9±2.7/100; P=0.0757). Forty-six script concordance tests were completed by FPs and 20 by general medicine residents. Script concordance test results did not seem significant between the subgroups. CONCLUSIONS: E-learning seems to be a good alternative to face-to-face training for Lyme disease. It seems to be more effective than face-to-face training for the acquisition of theoretical knowledge. The script concordance test evaluation of know-how did not show any difference between the two learning methods.

OBJECTIVES: Human babesiosis is a rare parasitic anthropozoonosis transmitted to humans by tick bites. Fifty-six cases of human babesiosis have been recorded in Europe. Two cases of babesiosis were reported in Alsace, France, in 2009. We performed a retrospective observational descriptive study to assess the epidemiology of the disease in Alsace. METHODS: Patients were included if they had a positive serology result for Babesia and/or a positive blood smear and/or a positive PCR result. The tests were performed in the microbiology laboratories of the university hospitals of Strasbourg, the civil hospitals of Colmar, and the hospital of Mulhouse between January 1, 2005 and December 31, 2015. Included patients were divided into three groups: definite case group (positive PCR or positive blood smear or seroconversion), possible case group (positive serology results without seroconversion with a compatible clinical picture and without other confirmed diagnoses), and incompatible case group (positive serology results without seroconversion, without compatible clinical picture and/or with other confirmed diagnoses). The compatible clinical picture was defined by the presence of flu-like symptoms and fever (≥38°C). RESULTS: Fifty-one patients had at least one positive result. Three cases were excluded (missing files). There were six definite cases, 12 possible cases, and 30 incompatible cases. All patients in the definite case group were immunocompetent. No deaths occurred. CONCLUSIONS: Human babesiosis is probably underdiagnosed due to its non-specific symptoms, lack of awareness about the disease, and the difficulty in making a diagnosis.

OBJECTIVE: Risk factors associated with treatment failure after the infectious disease specialist's (IDS) advice remain unknown. We aimed to identify these risk factors. METHODS: We included patients hospitalized in our tertiary care center who consulted an infectious disease specialist between January 2013 and April 2015. Treatment failure was defined by a composite criterion: signs of sepsis beyond Day 3, ICU admission, or death. Treatment success was defined by the patient's sustained clinical improvement. RESULTS: A total of 240 IDS recommendations were made. Diagnosis was changed for 64 patients (26.7%) and 50 patients experienced treatment failure after the IDS advice. In multivariate analysis, compliance with the IDS advice was associated with a higher rate of success (OR=0.09, 95%CI [0.01-0.67]). Variables associated with treatment failure in the multivariate analysis were Charlson comorbidity score at admission (OR=1.24, 95%CI [1.03-1.50]), a history of infection or colonization with multidrug-resistant bacteria (OR=8.27, 95%CI [1.37-49.80]), and deterioration of the patient's status three days after the IDS advice (OR=12.50, 95%CI [3.16-49.46]). CONCLUSION: Reassessing IDS recommendations could be interesting for specific patients to further adapt and improve them.

INTRODUCTION: Multidrug-resistant tuberculosis (MDR-TB) is a major public health problem with great regional disparities. The aim of this study was to describe the epidemiological, clinical, and therapeutics aspects of MDR-TB in Alsace, France. PATIENTS AND METHODS: A 10 years retrospective study, conducted for the years 2006 to 2016, of all MDR-TB cases diagnosed in Alsace and particularly in Strasbourg University Hospitals. RESULTS: We included 22 patients with MDR-TB of whom 90% originated from Eastern Europe, 13.6% had extensively-resistant strains, and 41% reported previously treated tuberculosis. Clinically, 86,4% had a pulmonary form of tuberculosis. The mean length of antibiotic treatment was 21 months with several changes of drugs because of severe side effects. The mean follow-up was 48 months, during which time 2 patients were lost from contact and the 20 remaining patients were cured. CONCLUSIONS: Management of MDR-TB is a real social and medical challenge. Our study shows that the therapeutic protocols used in the management of these patients lead to an unusually high rate of success despite the occurrence of several, sometimes severe, side effects.

The serodiagnosis of Lyme borreliosis is based on a two-tier strategy: a screening test using an immunoenzymatic technique (ELISA), followed if positive by a confirmatory test with a western blot technique for its better specificity. Lyme serology has poor sensitivity (30-40%) for erythema migrans and should not be performed. The seroconversion occurs after approximately 6 weeks, with IgG detection (sensitivity and specificity both>90%). Serological follow-up is not recommended as therapeutic success is defined by clinical criteria only. For neuroborreliosis, it is recommended to simultaneously perform ELISA tests in samples of blood and cerebrospinal fluid to test for intrathecal synthesis of Lyme antibodies. Given the continuum between early localized and disseminated borreliosis, and the efficacy of doxycycline for the treatment of neuroborreliosis, doxycycline is preferred as the first-line regimen of erythema migrans (duration, 14 days; alternative: amoxicillin) and neuroborreliosis (duration, 14 days if early, 21 days if late; alternative: ceftriaxone). Treatment of articular manifestations of Lyme borreliosis is based on doxycycline, ceftriaxone, or amoxicillin for 28 days. Patients with persistent symptoms after appropriate treatment of Lyme borreliosis should not be prescribed repeated or prolonged antibacterial treatment. Some patients present with persistent and pleomorphic symptoms after documented or suspected Lyme borreliosis. Another condition is eventually diagnosed in 80% of them.

INTRODUCTION: Mesenteric lymph node cavitation is an exceptional complication of celiac disease. We report four original observations of this syndrome, completed by a literature review. DISCUSSION: The analysis of 38 cases showed that this complication occurred exclusively in adults, with a mean age at diagnosis of 54 years. It revealed the celiac disease in the majority of cases. Hyposplenism was almost systematically associated. The risk of lymphoma appeared higher, especially enteropathy-associated T-cell lymphoma. The prognosis was poor with nearly 50% mortality and seemed related to the clinical response to the gluten-free diet. CONCLUSION: The severity of this complication deserves to be known and should lead to its research in celiac patients, especially in cases diagnosed in adulthood or in case of refractory disease.

Lyme borreliosis is transmitted en France by the tick Ixodes ricinus, endemic in metropolitan France. In the absence of vaccine licensed for use in humans, primary prevention mostly relies on mechanical protection (clothes covering most parts of the body) that may be completed by chemical protection (repulsives). Secondary prevention relies on early detection of ticks after exposure, and mechanical extraction. There is currently no situation in France when prophylactic antibiotics would be recommended. The incidence of Lyme borreliosis in France, estimated through a network of general practitioners (réseau Sentinelles), and nationwide coding system for hospital stays, has not significantly changed between 2009 and 2017, with a mean incidence estimated at 53 cases/100,000 inhabitants/year, leading to 1.3 hospital admission/100,000 inhabitants/year. Other tick-borne diseases are much more seldom in France: tick-borne encephalitis (around 20 cases/year), spotted-fever rickettsiosis (primarily mediterranean spotted fever, around 10 cases/year), tularemia (50-100 cases/year, of which 20% are transmitted by ticks), human granulocytic anaplasmosis (<10 cases/year), and babesiosis (<5 cases/year). The main circumstances of diagnosis for Lyme borreliosis are cutaneous manifestations (primarily erythema migrans, much more rarely borrelial lymphocytoma and atrophic chronic acrodermatitis), neurological (<15% of cases, mostly meningoradiculitis and cranial nerve palsy, especially facial nerve) and rheumatologic (mostly knee monoarthritis, with recurrences). Cardiac and ophtalmologic manifestations are very rarely encountered.

Ticks are a major group of arthropod vectors, characterized by the diversity of pathogens they transmit, by their impact on human and animal health, and by their socioeconomic implication especially in countries of the Southern Hemisphere. In Europe, Ixodes is the most important tick due to its wide distribution in the ecosystems and the variety of transmitted pathogens, in particular Borrelia (responsible for Lyme borreliosis), but also the tick-borne encephalitis virus. Their increased presence in the environment since the beginning of the 20th century is undeniable, because of major modifications in the biodiversity caused by humans. Increasing the awareness of health professionals and the general population is required to achieve better control of these infections. Thus, "a better understanding of these tick-borne diseases for a better control" is a simple but effective approach, considering their ubiquity in the environment and their particular mode of pathogen transmission (long-lasting blood meal for hard ticks and delayed transmission for bacteria and parasites). Finally, these ectoparasites are problematic due to the potential allergic reactions and other damages caused by their saliva, in humans and animals.

Lyme disease is a tick-borne bacterial disease with polymorphic clinical manifestations (cutaneous, rheumatological, and neurological). In recent years the issue of the diagnosis of this infection has been highly publicized on the Internet and other media in Europe and America. Some patients and physicians may share the perception that the diagnosis of the infection is not reliable in France. We reviewed current European and American guidelines on Lyme disease and performed a methodological evaluation of all guidelines. We retrieved 16 guidelines from seven countries. Our analysis revealed a global consensus regarding diagnosis at each stage of the infection. All guidelines indicate that the diagnosis is currently based on a two-tier serology at all stages of the infection, except for the early localized dermatological presentation known as Erythema migrans. One text of so-called guidelines has discordant recommendations when compared with the other guidelines, possibly explained by its low quality score. Contrary to the intense debate taking place on the Internet and in the European and American media, our analysis shows that the great majority of medical scientific guidelines with a high quality score, agree on the clinical diagnostic methods of Lyme disease.
