RESUMEN
BACKGROUND: During the first pandemic of COVID-19, early empirical antibiotic use rates for pneumonia varied widely. The benefit remains hypothetical. METHODS: We assessed the benefit of empirical antibiotic use at admission in patients hospitalized with COVID-19 pneumonia. We enrolled all adults admitted from 1 March to 30 April 2020 with symptoms for ≤14â days, a positive nasopharyngeal PCR or a highly suggestive CT scan. The primary outcome was mortality at Day 28. The secondary outcomes were transfer to the ICU, mechanical ventilation and length of hospital stay. To handle confounding-by-indication bias, we used a propensity score analysis, expressing the outcomes in the original and overlap weighted populations. RESULTS: Among 616 analysed patients, 402 (65%) received antibiotics. At Day 28, 102 patients (17%) had died, 90 (15%) had been transferred to the ICU and 24 (4%) had required mechanical ventilation. Mortality in patients who received antibiotics was higher before but not after weighting (OR 2.7, 95% CI 1.5-5.0, Pâ<â0.001 and OR 1.4, 95% CI 0.8-2.5, Pâ=â0.28, respectively. Antibiotic use had no benefit on: transfer to ICU before and after weighting (OR 1.3, 95% CI 0.8-2.3, Pâ=â0.30 and OR 1.1, 95% CI 0.6-1.9, Pâ=â0.78, respectively); mechanical ventilation before and after weighting (OR 0.5, 95% CI 0.2-1.1, Pâ=â0.079 and OR 0.75, 95% CI 0.3-2.0, Pâ=â0.55, respectively); and length of hospital stay before and after weighting (mean difference -0.02â±â0.5â days, Pâ=â0.97 and mean difference 0.54â±â0.75â days, Pâ=â0.48, respectively). CONCLUSIONS: We did not find any benefit of antibiotic use in patients hospitalized with COVID-19 pneumonia.
RESUMEN
Eosinophilic fasciitis is a rare connective tissue disease with a clinical presentation of scleroderma-like disease. We report a case of a 36-year-old female patient with a 6-month history of progressive stiffness involving her forearms and legs with joint pain. Laboratory examinations showed hypereosinophilia and elevated C-reactive protein. 18F FDG PET/CT showed diffuse and symmetrical increased uptake in the fasciae of the upper and lower limbs, sparing both muscles and fat tissues. Guided biopsy and histologic examination confirmed the diagnosis of eosinophilic fasciitis. 18F FDG PET/CT is of great help in the diagnosis of eosinophilic fasciitis, as it can guide the biopsy where FDG uptake is strongest and also help rule out possible associated neoplasms.

Hyperferritinemia can be the result of inflammation, infection, iron overload, or other uncommon pathologies including hemophagocytic lymphohistiocytosis (HLH). The significance of its elevation and its association with poor prognosis and critical clinical situations is unclear. To study the spectrum of diagnosis associated with elevated serum ferritin, we made a retrospective review of patients admitted to our center from 2015 and 2017 with serum ferritin levels above 2000 µg L-1. The H score was retrospectively assessed in all cases to evaluate the possible presence of HLH. The degree of ferritinemia found was compared with the evaluation of the undelying diagnosis and the results of laboratory examinations. A total of 77 patients were identified with a serum ferritin level >2000 µg L-1. Hematological malignancy was the most prevalent diagnosis with n=20; severe infection was next with n=14. Eleven patients were diagnosed with HLH. The hemophagocytosis pictures on bone marrow smear and mortality rate were significantly correlated with ferritin level above 6000 µg L-1 (p<0.01). The comparison of the HLH subgroup with the rest of the cohort showed that fever, cytopenia (anemia, leucopenia, neutropenia and thrombocytopenia), hemophagocytosis pictures, and major liver disturbances were significantly increased in the HLH subgroup. The H score was significantly elevated in the subgroup of patients with ferritin above 6000 µg L-1, with a significatively higher probability of HLH (p<0.01). The mortality rate at 3 months was significantly increased in the HLH subgroup. Extreme hyperferritin cannot be considered as a specific marker for the diagnosis. The cut off of 6000 µg L-1 is significantly associated with HLH diagnosis. The H score is an interesting screening tool that physicians should use to rule out the probability of HLH when facing critical clinical situations.

Wells' syndrome, also called eosinophilic cellulitis, is a rare eosinophilic dermatosis characterized by an unspecific inflammatory erythematous eruption often associated with systemic symptoms. Here we report the case of a 57-year-old female with bilateral painful pitting and pruritic feet progressive for two weeks despite one week of oral antibiotics. Skin biopsy was performed showing dermal eosinophilic infiltration. The patient showed a spontaneous progressive improvement of the condition. The presented case demonstrates both clinical and histologic presence of lesions of Wells' syndrome in the course of the disease. A careful diagnostic approach is needed because of the lack of specific signs. The global outcome is favorable and spontaneous resolution is possible.

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

BACKGROUND: Disseminated Histoplasmosis (DH) is a rare manifestation of Acquired Immune Deficiency Syndrome (AIDS) in European countries. Naso-maxillar osteolysis due to Histoplasma capsulatum var. capsulatum (Hcc) is unusual in endemic countries and has never been reported in European countries. Differential diagnoses such as malignant tumors, cocaine use, granulomatosis, vasculitis and infections are more frequently observed and could delay and/or bias the final diagnosis. CASE PRESENTATION: We report the case of an immunocompromised patient infected by Human Immunodeficiency Virus (HIV) with naso-maxillar histoplasmosis in a non-endemic country. Our aim is to describe the clinical presentation, the diagnostic and therapeutic issues. A 53-year-old woman, originated from Haiti, was admitted in 2016 for nasal deformation with alteration of general condition evolving for at least 6 months. HIV infection was diagnosed in 2006 and classified at AIDS stage in 2008 due to cytomegalovirus infection associated with pulmonary histoplasmosis. At admission, CD4 cell count was 9/mm3. Surgical biopsies were performed and ruled out differential or associated diagnoses. Mycological cultures identified Hcc and Blood Polymerase Chain Reaction (PCR) for Hcc was positive. The patient was given daily Amphothericin B liposomal infusion during 1 month. Hcc PCR became negative in the blood under treatment, and then oral switch by itraconazole was introduced. Antiretroviral treatment was reintroduced after a 3-week histoplasmosis treatment. Normalization of naso-maxillar mucosa enabled a palatal prosthesis. CONCLUSION: Naso-maxillar histoplasmosis is extremely rare; this is the first case ever reported in a non-endemic country. Differential diagnoses must be ruled out by conducting microbiologic tools and histological examinations on surgical biopsies. Early antifungal treatment should be initiated in order to prevent DH severe outcomes.

OBJECTIVES: Adequacy of imported malaria management with respect to guidelines in emergency departments (ED) is low. We aimed to identify factors associated with this non-compliance, and a potential impact of the SARS-CoV-2 pandemic. PATIENTS AND METHODS: Patients presenting with imported malaria at the ED of the hospital of Melun (France), from January 1, 2017 to February 14, 2022 were retrospectively included. RESULTS: Among 205 adults and 25 children, biological criteria of severity were fully assessed in 10% of cases; lactates (40%) and blood pH (21%) levels were the main missing variables. Of 74 patients (32%) with severe malaria, 13 were misclassified as uncomplicated malaria. The choice and dosage of treatment were adequate in 85% and 92% of cases, respectively. Treatment conformity was lower in severe malaria cases than in non-severe malaria cases (OR 0.15 [95% CI 0.07-0.31]), with oral treatment in 17 patients with severe malaria; conformity was higher in the intensive care unit (OR 4.10 [95% CI 1.21-13.95]). Patients with severe malaria were more likely to start treatment within 6hours than patients with uncomplicated malaria (OR 1.97 [95% CI 1.08-3.43]), as were patients infected by P.falciparum compared to other species (OR 4.63 [95% CI 1.03-20.90]). Consulting during the SARS-CoV-2 pandemic was the only organizational factor associated with a lower probability of adequate management (OR 0.42 [95% CI 0.23-0.75]). CONCLUSION: Initial evaluation of malaria severity and time to treatment administration could be improved. These have been adversely impacted by the SARS-CoV-2 pandemic.

OBJECTIVES: Infectious disease (ID) advice is a major part of antimicrobial stewardship programs. The objective of this study was to assess general practitioners' (GPs)' opinions and compliance with advice given by ID hotlines. PATIENTS AND METHODS: This multicenter survey was based on the 7-day assessment of initial advice requested by GPs to a hotline set up by volunteer hospital ID teams to record advice for 3 years. The primary endpoint was the GPs' satisfaction with the advice given by ID specialists. RESULTS: Ten ID teams participated in the study and recorded 4138 requests for advice, of which 1325 requests included a proposal for antibiotic therapy and justified a follow-up call at seven days. Only 398 follow-up calls (30%) were carried out because many GPs were not reachable. GPs were very satisfied with ID hotlines: 58% considered them indispensable and 38% very useful. The recommendations provided by ID specialists were followed by GPs in more than 80% of cases. The two main motivations for GPs to call the hotline were to get quick advice (86%) and to receive help in managing a patient (76%). CONCLUSIONS: The ID telephone consultations and advice systems for GPs are highly appreciated and are effective in terms of following the recommendations.

Hospital antibiotic management teams (AMTs) have been recommended, but, in France, their concrete implementation remains scarce and their effectiveness largely unevaluated. The objective of this investigation was to evaluate the appropriateness of antibiotic therapy (AT) for bloodstream infections (BSIs) at a 950-bed university teaching hospital, and assess the role of an AMT in improving it. A prospective analysis of all significant BSIs occurring outside of the intensive care unit (ICU) during an 18-month period was carried out. AT was deemed effective if at least one prescribed antibiotic was effective in vitro, and appropriate if it was consistent with local recommendations. Out of 574 BSIs, 512 were evaluated: 231 community-acquired, 206 nosocomial, and 75 healthcare-associated. For 219 (42.8%) BSIs, the AT initiated prior to AMT intervention proved to be effective and appropriate, inappropriate but effective in 136 (26.5%), and ineffective or absent in 157 (30.7%). In the multivariate analysis, hospital-acquired and other healthcare-associated BSIs, as well as catheter-borne (CB) infections, were associated with inappropriate or absent AT. A recommendation from the AMT was given and followed in 233 (94%) out of 249 BSIs requiring intervention. Initially, two-thirds of BSIs outside the ICU did not receive appropriate AT. Healthcare-associated BSIs should, therefore, be the priority target of AMTs.

Over several decades, the economic situation and consideration of patient quality of life have been responsible for increased outpatient treatment. It is in this context that outpatient antimicrobial treatment (OPAT) has rapidly developed. The availability of elastomeric infusion pumps has permitted prolonged or continuous antibiotic administration by dint of a mechanical device necessitating neither gravity nor a source of electricity. In numerous situations, its utilization optimizes administration of time-dependent antibiotics while freeing the patient from the constraints associated with infusion by gravity, volumetric pump or electrical syringe pump and, more often than not, limiting the number of nurse interventions to one or two a day. That much said, the installation of these pumps, which is not systematically justified, entails markedly increased OPAT costs and is liable to expose the patient to a risk of therapeutic failure or adverse effects due to the instability of the molecules utilized in a non-controlled environment, instability that necessitates close monitoring of their use. More precisely, a prescriber must take into consideration the stability parameters of each molecule (infusion duration, concentration following dilution, nature of the diluent and pump temperature). The objective of this work is to evaluate the different means of utilization of elastomeric infusion pumps in intravenous antibiotic administration outside of hospital. Following a review of the literature, we will present a tool for optimized antibiotic prescription, in a town setting by means of an infusion device.

Background: The outbreak of SARS-CoV-2 has resulted in anxiety, depression and post-traumatic stress disorder (PTSD) among hospital staff. The factors associated with this psychological impact remain to be determined. Methods: A cross-sectional study using an online questionnaire completed by the staff of a French hospital, two months after the SARS-CoV-2 outbreak. Results: Among the 353 participants (of whom 67% were healthcare professionals), 32% had symptoms of anxiety, 16% of depression and 16% of PTSD. Eleven per cent had initiated or increased treatment with sleeping pills, and 6% with anxiolytics. In a multivariate analysis, factors independently associated with anxiety were: change of professional team, having a relative infected by SARS-CoV-2 and a new/increased treatment with sleeping pills or anxiolytics. The only factor associated with depression was the feeling of risk during professional practice. The factors associated with PTSD were: having a relative infected by SARS-CoV-2, the feeling of risk during professional practice, the increase in smoking and treatment with sleeping pills. The observance of transmission preventive measures (TPM) was not associated with the psychological impact of SARS-CoV-2. A personal history of SARS-CoV-2 infection and age < 36 years were associated with insufficient use of protective equipment. Age < 36 years, and being a healthcare professional were associated with the non-observance of social distancing. Conclusion: The hospital staff displayed psychological consequences, resulting in the use of anxiolytics and sleeping pills. Belonging to a group with low-risk of severe disease was associated with lower observance of TPM.
RESUMEN
OBJECTIVE: We aimed to determine the proportion of elderly patients hospitalised for community-acquired pneumonia (CAP) in whom a 5-day antibiotic therapy would achieve clinical stability according to American Thoracic Society (ATS) criteria. METHODS: Patients aged≥75 years, hospitalised for CAP between November 2018 and August 2019, were analysed retrospectively. The American Thoracic Society (ATS) clinical stability criteria (temperature≤37°C, heart rate≤100/min, respiratory rate≤24/min, systolic blood pressure≥90mmHg, oxygen saturation≥90% in room air) were assessed after five days of antibiotic therapy. RESULTS: Seventy-five patients (mean age 88 years, 49% requiring oxygen therapy) were included. Six died, and at day 5, 36/69 (52%) fulfilled 4/5 stability criteria. The median duration of treatment was 9 days. In 28 patients (41%), it was ≤7 days. CONCLUSION: In 52% of elderly patients with CAP, a 5-day treatment regimen resulted in clinical stability.

A 50-year-old man had a sudden severe abdominal pain. An abdominal enhanced computed tomographic scan revealed irregular stenosis of the celiac artery, dissection of the hepatic artery and of the left common iliac artery, and mid stenosis of the right renal artery with extended renal parenchymal hypodensity. After careful evaluation, the patient was diagnosed with fibromuscular dysplasia. Systematic head and neck CT angiography revealed right vertebral arterial stenosis and saccular aneurysm of the left vertebral artery. We have chosen conservative medical treatment for the multifocal fibromuscular dysplasia.

OBJECTIVES: Reducing antibiotic consumption has now become a major public health priority. Reducing treatment duration is one of the means to achieve this objective. Guidelines on the therapeutic management of the most frequent infections recommend ranges of treatment duration in the ratio of one to two. The Recommendation Group of the French Infectious Diseases Society (SPILF) was asked to collect literature data to then recommend the shortest treatment durations possible for various infections. METHODS: Analysis of the literature focused on guidelines published in French and English, supported by a systematic search on PubMed. Articles dating from one year before the guidelines publication to August 31, 2015 were searched on the website. RESULTS: The shortest treatment durations based on the relevant clinical data were suggested for upper and lower respiratory tract infections, central venous catheter-related and uncomplicated primary bacteremia, infective endocarditis, bacterial meningitis, intra-abdominal, urinary tract, upper reproductive tract, bone and joint, skin and soft tissue infections, and febrile neutropenia. Details of analyzed articles were shown in tables. CONCLUSION: This work stresses the need for new well-conducted studies evaluating treatment durations for some common infections. Following the above-mentioned work focusing on existing literature data, the Recommendation Group of the SPILF suggests specific study proposals.

Cases of subcutaneous fat necrosis of the newborn (SCFN) and neonatal cold panniculitis have been reported most often secondary to perinatal distress or hypothermia. We present a case of a newborn infant who developed erythematous, indurated plaques on both cheeks and right shoulder following ice pack application for supraventricular tachycardia. The distinction between SCFN and cold panniculitis is important as SCFN may have complications such as hypercalcemia, whereas cold panniculitis is not associated with such sequelae. Clinicians should be aware of the diagnostic similarities and differences between these two conditions because of differences in potential serious sequelae.

The emergence of bacterial resistance and the lack of new antibiotics in the pipeline represent a public health priority. Maximizing the quality of antibiotic prescriptions is therefore of major importance in terms of adequate preparation and administration modalities. Adequate preparation prevents the inactivation of antibiotics and is a prerequisite to maximizing their efficacy (taking into account the pharmacokinetic/pharmacodynamic relationship) and to minimizing their toxicity. Many antibiotic guidelines address the choice of drugs and treatment duration but none of them exclusively address preparation and administration modalities. These guidelines are based on the available literature and offer essential data for a proper antibiotic preparation and administration by physicians and nurses. They may lead to a better efficacy and to a reduced antibiotic resistance. Such guidelines also contribute to a proper use of drugs and improve the interaction between inpatient and outpatient care for a better overall management of patients.
