Background: The diagnostic and treatment approaches for schistosomiasis in individual patients, outside endemic areas, are not standardised. This study aimed to appraise the reference documents that the experts from the TropNet and GeoSentinel networks use in practice as guidance for the clinical management of their patients with (suspect) schistosomiasis., Methods: We systematically appraised the following data from the referenced guidance documents: i) document type, ii) case definitions, iii) diagnostic techniques envisaged; iv) treatment recommendations; v) follow-up recommendations; vi) screening recommendations, and vii) symptom-based diagnostic suspicion., Results: Twenty-two of the 30 responders (73.3%) indicated 19 reference documents, three of which were WHO material not intended for individual clinical management. Only 4/19 (21.1%) documents were national recommendations; no international guideline was indicated. Case definitions were explicitly presented in only one document (1/19; 5.3%). Diagnostic tools were detailed in 11/16 (68.8%) and follow-up guidance in 8/16 (50%) documents. Treatment guidance was provided in 14/16 (87.5%) documents., Conclusions: Heterogeneity in clinical guidance was evident, although with noticeable overlap at least for chronic schistosomiasis. This confirms the need to formalise case definitions, which should be used to design trials to rigorously assess diagnostic tools and treatment schemes, and eventually come to harmonisation of clinical management guidance., Competing Interests: Declaration of Competing Interest ☒ The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2025.

Rationale for Review: Travel-related skin problems are a common reason for healthcare consultations. We present a clinical approach to diagnosing skin diseases in travellers, emphasizing clinical examination and epidemiological clues such as travel history, incubation time and at-risk behaviours., Key Findings: Skin problems or manifestations of systemic infections are the third most common health issue encountered by travellers, though their causes and frequency may vary based on the season and destination. The four most frequent skin conditions affecting travellers include arthropod bites, sunburns, hookworm-related cutaneous larva migrans (CLM) and bacterial skin and soft tissue infections. Dengue fever is the leading cause of febrile exanthema in travellers returning from Asia, Latin America and the Caribbean, while hookworm-related CLM is the most common cause of creeping dermatitis. Notable travel-related infections associated with pruritus include cercarial dermatitis, scabies, creeping dermatitis and urticaria. Acute schistosomiasis is the most common parasitic cause of acute urticaria in travellers. African tick-bite fever is the most frequently encountered rickettsiosis, typically presenting with single or multiple eschars., Conclusions: Diagnostic approaches emphasize the importance of travel history, at-risk activities during travel and lesion distribution. At-risk activities include sun exposure, walking barefoot, exposure to sea and fresh water, hiking in forested or jungle areas, exposure frequency to mosquitoes and sandflies, poor hygiene and food intake, drug history and sexual behaviour. Morphological characteristics (vesicula, bullae, pustule, papule, nodule, plaque, oedema and ulcer), distinguishing between single and multiple skin lesions, localized or generalized, and whether mucosa, scalp, palmar or plantar surfaces are affected, provide further clinical clues. Systemic signs and symptoms such as fever and pruritus will aid in the differential diagnosis algorithms. With a thorough clinical assessment and knowledge of geographic and exposure-related risk factors, the differential diagnosis of travel-associated skin conditions can be narrowed down allowing for timely clinical management., (© International Society of Travel Medicine 2024.

Objectives: Cutaneous tuberculosis (CTB) may be over-diagnosed due to imprecise diagnostic criteria or overlooked where mycobacterial investigations are negative. We evaluated the distinction between multibacillary and paucibacillary forms of CTB, as well as drug resistance and cure rates according to the results of mycobacterial investigations., Methods: We included retrospectively all patients diagnosed with CTB from 1995 to 2018 in two hospitals in Paris. Clinical forms were classified according to dermatological descriptions, into multibacillary (e.g. gumma, scrofuloderma, orificial TB) and paucibacillary forms (lupus vulgaris, verrucous tuberculosis, papulonecrotic tuberculids, nodular panniculitis). A distinction was made between microbiologically confirmed CTB and presumed CTB forms, which were treated presumptively. Cure was defined as the complete resolution of CTB in patients who completed anti-tuberculosis treatment., Results: Among the 124 patients with CTB, the most common forms were nodular panniculitis (30.6%), scrofuloderma (22.6%), gumma (18.6%), and lupus vulgaris (12.1%). Tuberculosis was confirmed in 78 patients (62.9%), among whom 13 (16.7%) exhibited resistance to anti-tuberculous drugs, and 46 were presumptively treated. Mycobacterial investigations were significantly more frequently positive for multibacillary (88.2%) than for paucibacillary CTB (39.3%) (p < 10 -6 ). Patients with mycobacterial evidence of CTB exhibited significantly better cure rates than patients without (96.7% vs. 66.7%, p < 10 -4 ), particularly among those with nodular panniculitis (100% vs. 63.0%, p < 10 -3 )., Conclusion: The distinction between paucibacillary and multibacillary CTB is relevant. Resistant strains may be isolated. Antituberculosis drugs should be prescribed with caution in cases of panniculitis in the absence of evidence of mycobacterial infection., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Masson SAS.

Terminology in schistosomiasis is not harmonised, generating misunderstanding in data interpretation and clinical descriptions. This study aimed to achieve consensus on definitions of clinical aspects of schistosomiasis in migrants and returning travellers. We applied the Delphi method. Experts from institutions affiliated with GeoSentinel and TropNet, identified through clinical and scientific criteria, were invited to participate. Five external reviewers revised and pilot-tested the statements. Statements focusing on the definitions of acute or chronic; possible, probable, or confirmed; active; and complicated schistosomiasis were managed through REDCap and replies managed in a blinded manner. Round 1 mapped the definitions used by experts; subsequent rounds were done to reach consensus, or quantify disagreement, on the proposed statements. Data were analysed with percentages, medians, and IQRs of a 5-point Likert scale. The study was terminated on the basis of consensus or stability-related and time-related criteria. 28 clinicians and scientists met the criteria for experts. 25 (89%) of 28 experts replied to Round 1, 18 (64%) of 28 to Round 2, 19 (68%) of 28 to Round 3, and 21 (75%) of 28 to at least two rounds. High-level consensus (79-100% agreement and IQRs ≤1) was reached for all definitions. Consensus definitions will foster harmonised scientific and clinical communication and support future research and development of management guidelines for schistosomiasis., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2024 Elsevier Ltd.

Lyme borreliosis (LB) existence in South America is debated, especially in the Amazon region. The infection with Lyme borreliae has never been reported in French Guiana where Borrelia burgdorferi sensu lato is not found in ticks. We describe the final diagnosis and presumed place of acquisition in patients consulting for suspicion of LB. We retrospectively collected data from all consecutive patients consulting for a suspicion of LB between 2010 and 2021 at Cayenne Hospital, French Guiana. Patients were classified by an adjudication committee as confirmed LB if they met the criteria of the French consensus, as possible LB if they had compatible symptoms and a good outcome after appropriate treatment, or excluded when a differential diagnosis was found. The place of acquisition was discussed in case of possible or confirmed case. Twenty-six patients were included. Rheumatologic symptoms were the most reported (88 %) followed by neurological symptoms (61 %). Twenty-four (92 %) of these patients were born out of French Guiana. Diagnosis of LB was considered as confirmed in 2 patients (8 %), for whom the place of acquisition was likely mainland France, and as possible in 3 patients (11 %) with early localized LB presumably acquired in French Guiana. Functional somatic disorders were diagnosed in 13 (50 %) patients whereas 9 (35 %) were found with another disease. This study did not confirm the acquisition of LB in French Guiana. However, three possible autochthonous cases encourage clinicians working in the Amazon area to stay aware of LB., Competing Interests: Declaration of Competing Interest Paul Le Turnier is currently benefiting from a grant from the Agence Nationale de Recherche sur le SIDA, les Hépatites et Maladies Infectieuses Emergentes (ANRS-MIE)., (Copyright © 2023 The Author(s).

Objectives: Positive direct antiglobulin tests (DATs) have been reported in cases of post-artesunate delayed hemolysis (PADH), but the causal role of auto-immune hemolysis remains unclear. We aimed to analyze a cohort of patients with PADH and DAT during severe malaria., Methods: We describe PADH and DAT results in a 7-year multi-center retrospective cohort of patients receiving artesunate for severe imported malaria., Results: Of 337 patients treated with artesunate, 46 (13.6%) had at least one DAT result within 30 days of treatment initiation, and 25/46 (54.3%) had at least one positive DAT. Among 40 patients with available data, 17 (42.5%) experienced PADH. Patient characteristics were similar for patients with a positive or negative DAT, and DAT positivity was not associated with PADH occurrence (P = 0.36). Among patients, 5/13 (38.5%) with a positive DAT after day 7 experienced PADH, compared to 10/13 (76.9%) of those with a negative DAT after day 7 (P = 0.11). Overall, 41% of patients required blood transfusions, and outcome was favorable without corticosteroids, even in cases of PADH., Conclusions: DAT does not appear to be a marker of PADH, but rather an indirect marker of an immune-mediated mechanism. DAT positivity should not lead to the administration of systemic corticosteroids during PADH., Competing Interests: Declarations of competing interest The authors have no competing interests to declare., (Copyright © 2023 The Author(s).

Objective: Among patients attending a multidisciplinary day-hospital program for persistent symptoms after COVID-19, we aimed i) to describe their characteristics ii) to present the medical conclusions (diagnoses and recommendations) and iii) to assess the patients' satisfaction and its correlates., Methods: For this retrospective chart review study, frequent symptoms were systematically assessed. Standardized questionnaires explored fatigue (Pichot scale), physical activity (Ricci & Gagnon scale), health-related quality of life (Short-Form Health Survey), anxiety and depressive symptoms (Hospital Anxiety and Depression scale) and associated psychological burden (Somatic-Symptom-Disorder B criteria Scale). Medical record conclusions were collected and a satisfaction survey was performed at 3-months follow-up., Results: Among 286 consecutive patients (median age: 44 years; 70% women), the most frequent symptoms were fatigue (86%), breathlessness (65%), joint/muscular pain (61%) and cognitive dysfunction (58%), with a median duration of 429 days (Inter-quartile range (IqR): 216-624). Questionnaires revealed low levels of physical activity and quality of life, and high levels of fatigue, anxiety, depression, and psychological burden, with 32% and 23% meeting the diagnostic criteria for a depressive or anxiety disorder, respectively. Positive arguments for a functional somatic disorder were found in 76% of patients, including 96% with no abnormal clinical or test findings that may explain the symptoms. Physical activity rehabilitation was recommended for 91% of patients. Patients' median satisfaction was 8/10 (IqR: 6-9)., Conclusion: Most patients attending this program presented with long-lasting symptoms and severe quality of life impairment, received a diagnosis of functional somatic disorder, and reported high levels of satisfaction regarding the program., Competing Interests: Declaration of Competing Interest The authors have no competing interests to report., (Copyright © 2023 Elsevier Inc.

Background: In endemic foci, the use of an aquaphilic cream containing paromomycin with/without gentamicin to treat cutaneous leishmaniasis (CL) is safe, painless and cures 78-82% of patients with New and Old World CL. Self-application in travelers requires evaluation., Methods: Travelers with 1-10 lesions of confirmed CL were prospectively treated with the paromomycin-gentamicin formulation (WR279396, 2012-2017, Group 1) and carefully follow up, or treated with a locally produced paromomycin-only cream (2018-2022, Group 2). The cream was applied once under supervision, then self-applied daily for 20-30 days. A cured lesion was defined as 100% re-epithelialization at day 42 without relapse at three months., Results: Medical features were similar in Group 1 (17 patients), and Group 2 (23 patients). Patients were infected with either Leishmania major, L. infantum, L. killicki, L. guyanensis, L. braziliensis, or L. naiffi. Intention-to-treat and per-protocol cure rates were 82% (95% confidence interval (CI) [64.23;100.00]) and 87% (95% CI [71,29;100.00]) in Group 1, and 69% (95% CI [50.76; 88.37]) and 76% (95% CI [57.97; 94.41]) in Group 2. In the pooled Group 1&2, 75% (95% CI [61.58;88.42]) (30/40) and 81% (95% CI [68,46;93.6]) (30/37) of patients were cured in intention-to-treat and per-protocol, respectively. There were no significant differences observed in the success rates between Old World and New World CL (83.3% vs. 60%, p = 0.14). Prospective observations in Group 1 showed that adverse events were mainly pruritus (24%) and pain (18%) on lesions (all mild or moderate). No mucosal involvement was observed in either group., Discussion: In this representative population of travelers who acquired CL either in the Old or New World, the 81% per-protocol cure rate of a self-applied aminoglycoside cream was similar to that observed in clinical trials., Competing Interests: I have read the journal’s policy and the authors of this manuscript have the following competing interests : PB is member of the scientific advisory committee of Drugs for Neglected Diseases initiative., (Copyright: © 2023 Mouri et al.

Rationale for Review: Chikungunya outbreaks continue to occur, with changing epidemiology. Awareness about chikungunya is low both among the at-risk travellers and healthcare professionals, which can result in underdiagnosis and underreporting. This review aims to improve awareness among healthcare professionals regarding the risks of chikungunya for travellers., Key Findings: Chikungunya virus transmission to humans occurs mainly via daytime-active mosquitoes, Aedes aegypti and Aedes albopictus. The areas where these mosquitoes live is continuously expanding, partly due to climate changes. Chikungunya is characterized by an acute onset of fever with joint pain. These symptoms generally resolve within 1-3 weeks, but at least one-third of the patients suffer from debilitating rheumatologic symptoms for months to years. Large outbreaks in changing regions of the world since the turn of the 21st century (e.g. Caribbean, La Réunion; currently Brazil, India) have resulted in growing numbers of travellers importing chikungunya, mainly to Europe and North America. Viremic travellers with chikungunya infection have seeded chikungunya clusters (France, United States of America) and outbreaks (Italy in 2007 and 2017) in non-endemic countries where Ae. albopictus mosquitoes are present. Community preventive measures are important to prevent disease transmission by mosquitoes. Individual preventive options are limited to personal protection measures against mosquito bites, particularly the daytime-active mosquitos that transmit the chikungunya virus. Candidate vaccines are on the horizon and regulatory authorities will need to assess environmental and host risk factors for persistent sequelae, such as obesity, age (over 40 years) and history of arthritis or inflammatory rheumatologic disease to determine which populations should be targeted for these chikungunya vaccines., Conclusions/recommendations: Travellers planning to visit destinations with active CHIKV circulation should be advised about the risk for chikungunya, prevention strategies, the disease manifestations, possible chronic rheumatologic sequelae and, if symptomatic, seek medical evaluation and report potential exposures., (© International Society of Travel Medicine 2023.

We aimed to describe the clinical characteristics, management, and residual symptoms (RS) in patients with definite and possible Lyme neuroborreliosis (LNB). We conducted a retrospective French multicenter cohort study (2010-2020). Cases of LNB were defined as clinical manifestations attributed to LNB and a positive Borrelia-specific intrathecal antibody index (AI) ("possible" LNB) and with pleocytosis ("definite" LNB). Risk factors of RS were determined using a logistic regression model. We included 138 adult patients with a positive AI. Mean age was 59.5 years (± 14.7). The median duration of symptoms before diagnosis was 1.0 [0.5-4.0] months. The most frequent manifestation was radicular pain (n = 79, 57%). Complete cerebrospinal fluid (CSF) leukocyte analysis was available in 131 patients, of whom 72 (55%) had pleocytosis. Patients with definite LNB had a shorter duration of symptoms (median 1.0 [0.5-2.6] vs. 3.0 [0.6-7.0] months, p < 0.01) and more radicular pain (74% vs 44%, p < 0.01) than patients with possible LNB. At the last visit (median duration of follow-up: 70 [30-175] days), 74/124 patients (59.7%) reported RS, mostly radicular pain (n = 31, 25%). In multivariate analysis, definite LNB (OR = 0.21 [0.05-0.931], p = 0.039) and duration of symptoms less than 3 months (OR = 0.04 [0.01-0.37], p = 0.005) were protective factors against RS at last follow-up. Our study highlights the challenges of LNB management, especially for patients with a positive AI without pleocytosis, questioning whether LB is still ongoing or not. Early diagnosis and treatment are important to improve outcomes and to lower potential RS., (© 2023. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Background: Treatment of multidrug-resistant (MDR) tuberculosis with linezolid is characterized by high rates of adverse events. Evidence on therapeutic drug monitoring to predict drug toxicity is scarce. This study aimed to evaluate the association of linezolid trough concentrations with severe toxicity., Methods: We retrospectively assessed consecutive patients started on linezolid for MDR tuberculosis between 2011 and 2017. The primary outcome was severe mitochondrial toxicity (SMT) due to linezolid, defined as neurotoxicity or myelotoxicity leading to drug discontinuation. The impact of plasma linezolid trough concentrations >2 mg/L was assessed in multivariate Cox proportional hazards models including time-varying covariates., Results: SMT occurred in 57 of 146 included patients (39%) at an incidence rate of 0.38 per person-year (95% confidence interval, .30-.49). A maximum linezolid trough concentration >2 mg/L was detected in 52 patients (35.6%), while the mean trough concentration was >2 mg/L in 22 (15%). The adjusted hazard ratio for SMT was 2.35 (95% confidence interval, 1.26-4.38; P = .01) in patients with a mean trough concentration >2 mg/L and 2.63 (1.55-4.47; P < .01) for SMT after the first detection of a trough concentration >2 mg/L. In an exploratory analysis, higher maximum trough concentrations were dose-dependently associated with toxicity, while lowering elevated trough concentrations did not restore baseline risk., Conclusions: Linezolid trough concentrations >2 mg/L are strongly associated with the development of severe treatment-emergent toxicity in patients treated for MDR tuberculosis. Pending further prospective evidence, an individual risk-benefit assessment on the continuation of linezolid treatment is warranted in any patient with trough concentrations >2 mg/L., Competing Interests: Potential conflicts of interest.

The use of herbal tea with Artemisia annua by travelers and traditional communities in Africa has increased in recent years as a supposed form of malaria prophylaxis, although its use is not recommended due to lack of efficacy. The risk of severe malaria complications that can lead to death is real regarding said behavior, and awareness needs to be raised. We report a case of severe Plasmodium falciparum malaria imported in the Amazon rainforest by a traveler returning from Cameroon who treated himself with Artemisia annua herbal tea.

Strongyloidiasis is a frequent and often unrecognized parasitic disease because of the frequently asymptomatic nature and lack of sensitivity of diagnostic tests. Under conditions of immunosuppression (particularly systemic corticosteroid treatment), potentially fatal dissemination may occur. Thus, prevention and early diagnosis are important. Larva currens is a rare and pathognomonic cutaneous sign of strongyloidiasis, but is poorly described because of its unpredictable and fleeting occurrence. We report seven imported cases of larva currens seen in Paris between 1990 and 2020. We illustrate the clinical and biological features of this specific but uncommon sign of strongyloidiasis with clinical pictures. There were three males and four females, aged between 29 and 58 years. There were five migrants from endemic countries, one tourist and one expatriate. Digestive disorders were the main extracutaneous signs. All patients had eosinophilia above 0.5 G/L. All cases were confirmed by stool tests. All were cured with ivermectin. The rapidity and the short duration of the creeping eruption distinguish it from other parasitoses. Ivermectin is a treatment of choice. The key point is to think about preventing disseminated strongyloidiasis before giving corticosteroids not only among migrants but also among expatriates and tourists in endemic countries.

Objective: To identify factors associated with posttraumatic stress symptoms (PTSS) 3 and 6 months after the discharge of patients hospitalized for COVID-19., Methods: Patients hospitalized for COVID-19 between March 1 and July 31, 2020, were included in a longitudinal study. Clinical assessments were conducted with online auto-questionnaires. PTSS were assessed with the Posttraumatic Stress Disorder Checklist Scale (PCLS). We screened for several putative factors associated with PTSS, including socio-demographic status, hospitalization in an intensive care unit, history of psychiatric disorder, the Hospital Anxiety and Depression Scale, the Peritraumatic Dissociative Experiences Questionnaire, and the home-to-hospital distance. Bivariate and multilinear regression analyses were performed to evaluate their association with PTSS., Results: 119 patients were evaluated 3 months after hospital discharge, and a subset of 94 were evaluated 6 months after discharge. The prevalence of PTSS was 31.9% after 3 months and 30.9% after 6 months. Symptoms of anxiety and depression and history of psychiatric disorder were independently associated with PTSS. Additionally, dissociative experiences during hospitalization (β = 0.35; P  < .001) and a longer home-to-hospital distance (β = 0.07; P  = .017) were specifically associated with PTSS 3 and 6 months after discharge, respectively., Conclusions: Patients with COVID-19 showed persistent high scores of PTSS up to 6 months after discharge from the hospital. In this specific pandemic setting, PTSS were associated with high rates of dissociative experiences during hospitalization and a longer home-to-hospital distance due to the saturation of health care facilities. These results can foster early identification and better prevention of PTSS after hospitalization for COVID-19., Trial Registration: ClinicalTrials.gov identifier: NCT04362930., (© Copyright 2022 Physicians Postgraduate Press, Inc.)

The optimal treatment for osteoarticular infection due to multidrug-resistant tuberculosis strains (MDR-OATB) remains unclear. This study aims to evaluate the diagnosis, management and outcome of MDR-OATB in France. We present a case series of MDR-OATB patients reviewed at the French National Reference Center for Mycobacteria between 2007 and 2018. Medical history and clinical, microbiological, treatment and outcome data were collected. Twenty-three MDR-OATB cases were reported, representing 3% of all concurrent MDR-TB cases in France. Overall, 17 were male, and the median age was 32 years. Six patients were previously treated for TB, including four with first-line drugs. The most frequently affected site was the spine ( n = 16). Bone and joint surgery were required in 12 patients. Twenty-one patients (91%) successfully completed the treatment with a regimen containing a mean of four drugs (range, 2-6) for a mean duration of 20 months (range, 13-27). Overall, high rates of treatment success were achieved following WHO MDR-TB treatment guidelines and individualized patient management recommendations by the French National TB Consilium. However, the optimal combination of drugs, duration of treatment and role of surgery in the management of MDR-OATB remains to be determined.

Background: In addition to general measures, pharmacological treatment is the basis of the management of scabies. No recent data in real-life are available on the efficacy and safety of 10% benzyl benzoate emulsion for skin application administered as monotherapy., Method: This prospective, multicenter, French observational study comprised a registry and a prospective cohort with a follow-up at 28 days and a telephone call at week 12. To participate in the registry, patients had to be over 1 month old, ambulatory, presenting common, nonhyperkeratotic, untreated scabies. To be included in the cohort, patients had to be included in the registry and treated with two applications of 10% benzyl benzoate emulsion 8 days apart. The primary endpoint was cure at day 28., Results: Of the 186 patients included in the registry, 116 were included in the cohort. Fourteen patients were included in the cohort without being included in the registry, which led to a total of 130 patients in the cohort. At day 28, 119/130 (91.5%; 95% CI 85.4-95.6%) were clinically cured. The cure was confirmed by dermoscopy in 44/47 patients (93%). Among the 130 patients, the cure rate was 82% at week 12. Of the 119 patients cured at day 28, the rate of cure at week 12 was 89.9%., Conclusion: In real life, two applications of 10% benzyl benzoate emulsion 8 days apart provides high cure rates in patients with common scabies., (© 2021 the International Society of Dermatology.)

Introduction: Persistent symptoms have recently emerged as a clinical issue in COVID-19. We aimed to assess the prevalence and risk factors in symptomatic non-hospitalized individuals with mild COVID-19., Methods: We performed a prospective cohort study of symptomatic COVID-19 outpatients, from March to May 2020, with weekly phone calls from clinical onset until day 30 and up to day 60 in case of persistent symptoms. The main outcomes were the proportion of patients with complete recovery at day 30 and day 60 and factors associated with persistent symptoms., Results: We enrolled 429 individuals mostly women (72.5%) and healthcare workers (72.5%), with a median age of 41.6 years [IQR 30-51.5]. Symptoms included: cough (69.7%), asthenia (68.8%), anosmia (64.8%), headaches (64.6%), myalgia (62.7%), gastrointestinal symptoms (61.8%), fever (61.5%), and ageusia (60.8%). Mean duration of disease was 27 days (95%CI: 25-29). The rate of persistent symptoms was 46.8% at day 30 and 6.5% at day 60 consisting in asthenia (32.6%), anosmia (32.6%), and ageusia (30.4%). The probability of complete recovery was 56.3% (95%CI: 51.7-61.1) at day 30 and 85.6% (95%CI: 81.2-89.4) at day 60. Factors associated with persistent symptoms were age>40 (HR 0.61), female sex (HR 0.70), low cycle threshold (HR 0.78), and ageusia (HR 0.59)., Conclusions: COVID-19 - even in its mild presentation - led to persistent symptoms (up to one month) in nearly half of individuals. Identification of risk factors such as age, gender, ageusia and viral load is crucial for clinical management and argues for the development of antiviral agents., (Copyright © 2021 Elsevier Masson SAS.

Objectives: We report the characteristics of Mycoplasmagenitalium (MG) infection in patients from a STI center in Paris. We evaluated outcomes after treatment., Methods: We included all patients tested for MG, Chlamydiatrachomatis (CT) and Neisseria gonorrhoeae (NG) infection in our center from January 2017 to December 2018, using multiplex PCR on urine specimen, vaginal or rectal swabs. We collected data regarding sex, age, HIV status, PrEP use, sexual behavior, NG and CT co-infection, symptoms and treatment., Results: MG infection prevalence was 7% (397/5586) (95% CI 6.4-7.8). It ranged from 4.6% in patients consulting for routine STI testing (3.9% in women, 5% in men), to 16% in HIV-positive patients and 25% in PrEP users. Among the 397 MG infected patients, 351 (88%) were asymptomatic and 87 (22%) were co-infected with NG or CT. Among the 270 (68%) treated patients, 249 (92%) received azithromycin. Failure rate was 74% in the 103 patients tested post-treatment. Treatment failure tended to be higher with azithromycin single dose than with 5-day azithromycin (88% vs. 70%; P=0.07). Azithromycin and moxifloxacin were used as second-line treatment in 24 and 23 patients, respectively. Post-treatment PCR remained positive in 55% of the 44 tested patients with a better eradication rate with moxifloxacin than with azithromycin (70% vs. 33%; P=0.04)., Conclusion: MG infection is highly prevalent in PrEP users and HIV-positive patients and is mostly asymptomatic. Management of MG infection should be tailored and adapted to the risk of antibiotic resistance and reinfection., (Copyright © 2021 Elsevier Masson SAS. All rights reserved.)

Background: Identification of prognostic factors in COVID-19 remains a global challenge. The role of smoking is still controversial. Methods: PCR-positive in- and outpatients with symptomatic COVID-19 from a large French University hospital were systematically interviewed for their smoking status, use of e-cigarette, and nicotinic substitutes. The rates of daily smokers in in- and outpatients were compared using the same smoking habit questionnaire to those in the 2019 French general population, after standardisation for sex and age. Results: The inpatient group was composed of 340 patients, median age of 66 years: 203 men (59.7%) and 137 women (40.3%), median age of both 66 years, with a rate of 4.1% daily smokers (CI 95% [2.3-6.9]) (5.4% of men and 2.2% of women). The outpatient group was composed of 139 patients, median age of 44 years: 62 men (44.6%, median age of 43 years) and 77 women (55.4%, median age of 44 years). The daily smoker rate was 6.1% (CI 95% [2.7-11.6], 5.1% of men and 6.8% of women). Amongst inpatients, daily smokers represented 2.2 and 3.4% of the 45 dead patients and of the 29 patients transferred to ICU, respectively. The rate of daily smokers was significantly lower in patients with symptomatic COVID-19, as compared to that in the French general population after standardisation by age and sex, with standardised incidence ratios (SIRs) of 0.24 [0.12-0.48] for outpatients and 0.24 [0.14-0.40] for inpatients. Conclusions: Daily smoker rate in patients with symptomatic COVID-19 is lower as compared to the French general population., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Miyara, Tubach, Pourcher, Morélot-Panzini, Pernet, Haroche, Lebbah, Morawiec, Gorochov, Caumes, Hausfater, Combes, Similowski and Amoura.)

Introduction: Corynebacterium striatum is a non- Diphteriae commensal bacterium with a wide range of pathogenicity. The identification of multidrug-resistant (MDR) C. striatum is concerning because drug susceptibility testing is not usually performed in microbiology laboratories. There is no consensus yet on the treatment of septic thrombophlebitis in this situation., Case Report: We report here the first case of a quinquagenarian patient with a history of AIDS and fungic endocarditis, who was diagnosed with a nosocomial thrombophlebitis in the right jugular vein caused by C. striatum . Bitherapy with daptomycin for 12 days and linezolid for 23 days was combined with a therapeutic anticoagulant. The follow-up included weekly cervical ultrasound controls. The efficiency of the treatment and the stability of the lesions allowed us to alleviate the medication with a prophylactic dose of anticoagulant. The patient was discharged from hospital and showed no signs of recurrence after 12 months., Conclusion: The lack of consensus relative to the management of septic thrombophlebitis precludes the validation of a specific treatment for the condition. Our results suggest that a combination that includes removal of the medical device is needed. A total of 6 weeks of antibiotherapy should be applied, starting with 2 weeks of vancomycin or a combination of antibiotitherapy with daptomycin in order to reduce the bacterial load and avoid resistance. Six weeks of anticoagulation therapy is effective., Competing Interests: The authors declare that there are no conflicts of interest., (© 2021 The Authors.)

Background: Data from nonrandomized studies have suggested that hydroxychloroquine could be an effective therapeutic agent against coronavirus disease 2019 (COVID-19)., Methods: We conducted an observational, retrospective cohort study involving hospitalized adult patients with confirmed, mild to severe COVID-19 in a French university hospital. Patients who received hydroxychloroquine (200 mg 3 times daily dosage for 10 days) on a compassionate basis in addition to standard of care (SOC) were compared with patients without contraindications to hydroxychloroquine who received SOC alone. A propensity score-weighted analysis was performed to control for confounders: age, sex, time between symptom onset and admission ≤ 7 days, Charlson comorbidity index, medical history of arterial hypertension, obesity, National Early Warning Score 2 (NEWS2) score at admission, and pneumonia severity. The primary endpoint was time to unfavorable outcome, defined as: death, admission to an intensive care unit, or decision to withdraw or withhold life-sustaining treatments, whichever came first., Results: Data from 89 patients with laboratory-confirmed COVID-19 were analyzed, 84 of whom were considered in the primary analysis; 38 patients treated with hydroxychloroquine and 46 patients treated with SOC alone. At admission, the mean age of patients was 66 years, the median Charlson comorbidity index was 3, and the median NEWS2 severity score was 3. After propensity score weighting, treatment with hydroxychloroquine was not associated with a significantly reduced risk of unfavorable outcome (hazard ratio, 0.90 [95% confidence interval, .38-2.1], P = .81). Overall survival was not significantly different between the 2 groups (hazard ratio, 0.89 [0.23; 3.47], P = 1)., Conclusion: In hospitalized adults with COVID-19, no significant reduction of the risk of unfavorable outcomes was observed with hydroxychloroquine in comparison to SOC. Unmeasured confounders may have persisted however, despite careful propensity-weighted analysis and the study might be underpowered. Ongoing controlled trials in patients with varying degrees of initial severity on a larger scale will help determine whether there is a place for hydroxychloroquine in the treatment of COVID-19. In hospitalized adults with COVID-19, no significant reduction of the risk of unfavorable outcomes was observed with hydroxychloroquine in comparison to SOC., (© The Author(s) 2020.

Background: Intravenous artesunate is the World Health Organization-recommended first-line treatment for severe malaria worldwide, but it is still not fully licensed in Europe. Observational studies documenting its safety and efficacy in imported malaria are thus essential., Methods: We prospectively collected clinical and epidemiological features of 1391 artesunate-treated patients among 110 participant centers during the first 7 years (2011-2017) of a national program implemented by the French Drug Agency., Results: Artesunate became the most frequent treatment for severe malaria in France, rising from 9.9% in 2011 to 71.4% in 2017. Mortality was estimated at 4.1%. Treatment failure was recorded in 27 patients, but mutations in the Kelch-13 gene were not observed. Main reported adverse events (AEs) were anemia (136 cases), cardiac events (24, including 20 episodes of conduction disorders and/or arrhythmia), and liver enzyme elevation (23). Mortality and AEs were similar in the general population and in people with human immunodeficiency virus, who were overweight, or were pregnant, but the only pregnant woman treated in the first trimester experimented a hemorrhagic miscarriage. The incidence of post-artesunate-delayed hemolysis (PADH) was 42.8% when specifically assessed in a 98-patient subgroup, but was not associated with fatal outcomes or sequelae. PADH was twice as frequent in patients of European compared with African origin., Conclusions: Artesunate was rapidly deployed and displayed a robust clinical benefit in patients with severe imported malaria, despite a high frequency of mild to moderate PADH. Further explorations in the context of importation should assess outcomes during the first trimester of pregnancy and collect rare but potentially severe cardiac AEs., (© The Author(s) 2021.

We present a case of Erysipelothrix rhusiopathiae spondylodiscitis in an otherwise healthy man, occurring 1 year after exposure. The patient was cured after 6 weeks of treatment with amoxicillin followed by ciprofloxacin without surgery. Erysipelothrix rhusiopathiae can cause severe osteoarticular infections with a delayed presentation following exposure to the pathogen., (© The Author(s) 2021.

Introduction: Neisseria elongata (NE), a Gram-negative, rod-shaped organism, was previously thought to be non-pathogenic. However, in recent years it has become increasingly recognized as a rare cause of infective endocarditis. In this paper, we report a case of NE infective endocarditis and provide a review of the literature., Objectives: To describe a case of NE endocarditis, and to review the literature in search of any similar cases of this rare condition., Case Report: Our patient is a 77-year-old, otherwise healthy female patient who was found to have mitral valve endocarditis with valve regurgitation., Discussion: NE endocarditis is a rare condition that typically affects the left cardiac chambers and is associated with high risk of embolization. A literature review retrieved 35 other cases., Conclusions: Our report underlines the rarity of NE endocarditis, insofar as relatively few cases have been reported. The bacterium presents similarities with HACEK organisms and can potentially cause infective endocarditis., (Copyright © 2021 Elsevier Masson SAS. All rights reserved.)

Background: Early detection of imported multidrug-resistant tuberculosis (MDR-TB) is crucial, but knowledge gaps remain about migration- and travel-associated MDR-TB epidemiology. The aim was to describe epidemiologic characteristics among international travellers and migrants with MDR-TB., Methods: Clinician-determined and microbiologically confirmed MDR-TB diagnoses deemed to be related to travel or migration were extracted from GeoSentinel, a global surveillance network of travel and tropical medicine clinics, from January 2008 through December 2020. MDR-TB was defined as resistance to both isoniazid and rifampicin. Additional resistance to either a fluoroquinolone or a second-line injectable drug was categorized as pre-extensively drug-resistant (pre-XDR) TB, and as extensively drug-resistant (XDR) TB when resistance was detected for both. Sub-analyses were performed based on degree of resistance and country of origin., Results: Of 201 patients, 136 had MDR-TB (67.7%), 25 had XDR-TB (12.4%), 23 had pre-XDR TB (11.4%) and 17 had unspecified MDR- or XDR-TB (8.5%); 196 (97.5%) were immigrants, of which 92 (45.8%) originated from the former Soviet Union. The median interval from arrival to presentation was 154 days (interquartile range [IQR]: 10-751 days); 34.3% of patients presented within 1 month after immigration, 30.9% between 1 and 12 months and 34.9% after ≥1 year. Pre-XDR- and XDR-TB patients from the former Soviet Union other than Georgia presented earlier than those with MDR-TB (26 days [IQR: 8-522] vs. 369 days [IQR: 84-827]), while patients from Georgia presented very early, irrespective of the level of resistance (8 days [IQR: 2-18] vs. 2 days [IQR: 1-17])., Conclusions: MDR-TB is uncommon in traditional travellers. Purposeful medical migration may partly explain differences in time to presentation among different groups. Public health resources are needed to better understand factors contributing to cross-border MDR-TB spread and to develop strategies to optimize care of TB-infected patients in their home countries before migration., (© International Society of Travel Medicine 2021.

Objectives: Since the 2000s, there has been an increase in prevalence of neurosyphilis (NS) and ocular syphilis (OS). As data about symptomatic NS/OS is limited, this study aims to assess the characteristics of symptomatic NS/OS, according to HIV status., Methods: We compared the clinical and biological presentation of early symptomatic NS/OS and its outcome in HIV-positive and HIV-negative patients., Results: Ninety-six patients (93% men, 49% HIV-positive) were included from 2000 to 2016 in two centers, with 67 (69%) having OS, 15 (16%) NS, and 14 (14%) both. HIV-positive patients were younger (P=0.006) and more likely to be males having sex with males (P=0.00048) or to have a history of syphilis (P=0.01). Among 81 OS, there were 43 posterior uveitis (57%), and bilateral involvement was more common in HIV-positive patients (62% versus 38%, P=0.045). Among 29 NS there were 21 cases of cranial nerve involvement (72%), seven meningitis (24%) and 11 paresthesia (38%). Involvement of the VIII th cranial nerve was the most common (16 cases). Treponemal tests were more commonly found positive in cerebrospinal fluid in HIV-positive patients (88% versus 76%, P=0.04). Visual acuity (VA) always improved after treatment (initial VA logMAR 0.8±0.8 versus 0.1±0.1 at 3 months), but 32% and 18% of the patients still had neurological or ocular impairment respectively six and 12 months after treatment. Non-treponemal serological reversion was observed in 43/50 patients (88%) at six months., Conclusion: HIV infection has no consequence on the outcome of NS and OS. Sequelae are common, emphasizing the importance of prevention, and screening, and questioning enhanced treatment., (Copyright © 2020 Elsevier Masson SAS. All rights reserved.)

Objectives: Overdiagnosis of lyme borreliosis leads to unnecessary and increasingly common antimicrobial treatments. We aimed to evaluate patients receiving long-term antimicrobial treatment for lyme borreliosis., Methods: We included patients referred to a Parisian teaching hospital between January 1st, 2014 and June 30th, 2019, with a presumed diagnosis of lyme borreliosis for which they were treated with antimicrobials for at least 6 months., Results: Fifteen patients were included (11 women and mean age 44 years). The mean antimicrobial treatment duration was 476 days (180-942). The mean number of antimicrobials was 6.8 per patient (1-18). None of the 15 patients had lyme borreliosis. Nine patients were diagnosed with a mental disorder., Conclusion: Overdiagnosis and overtreatment of lyme borreliosis put patients at risk of undiagnosed illnesses and multiple adverse effects of unjustified treatments. The clinical management of such patients requires a comprehensive approach including expertise in mental disorders., (Copyright © 2020 Elsevier Masson SAS. All rights reserved.)

Background: Pulmonary tuberculosis (TB) is the most frequent site of TB and the one leading its spread worldwide. Multiple specimens are commonly collected for TB diagnosis including those requiring invasive procedures. This study aimed to review the sampling strategy for the microbiological diagnosis of pulmonary TB., Methods: A retrospective analysis of collected samples from September 1st 2014 to May 1st 2016 in the Bacteriology laboratory of Pitié-Salpêtrière Hospital (Paris, France) was performed. All the samples collected in patients aged over 18 years for the bacteriological diagnosis of pulmonary TB were included., Results: A total of 6267 samples were collected in 2187 patients. One hundred and twenty-six patients (6%) had a culture confirmed pulmonary TB. Among them, multiple sputum collections were sufficient for TB diagnosis in 63.5%, gastric lavages permitted to avoid bronchoscopy in only 7.1%, and bronchoscopy was necessary in 29.4%. The culture positivity of sputa (8.6%) was higher than that of bronchial aspirations (3.1%), bronchiolo-alveolar lavages (BAL) (2.3%) or gastric lavages (4.8%) (P<0.001). From its 70.0% theoretical PPV value, the 46.1% selection in bronchial aspirations allocated to molecular test increased PPV up to 88.9%., Conclusions: Based on our data, we suggest to collect sputum consistently. If smear negative a bronchoscopy should be performed and molecular diagnosis be performed on a subset of bronchial aspirations based on expertise of the bronchoscopist., (Copyright © 2021 SPLF and Elsevier Masson SAS.

Anecdotal evidence rapidly accumulated during March 2020 from sites around the world that sudden hyposmia and hypogeusia are significant symptoms associated with the SARS-CoV-2 pandemic. Our objective was to describe the prevalence of hyposmia and hypogeusia and compare it in hospitalized and non-hospitalized COVID-19 patients to evaluate an association of these symptoms with disease severity. We performed a cross-sectional survey during 5 consecutive days in March 2020, within a tertiary referral center, associated outpatient clinic, and two primary care outpatient facilities in Paris. All SARS-CoV-2-positive patients hospitalized during the study period and able to be interviewed (n = 198), hospital outpatients seen during the previous month (n = 129), and all COVID-19-highly suspect patients in two primary health centers (n = 63) were included. Hospitalized patients were significantly more often male (64 vs 40%) and older (66 vs 43 years old in median) and had significantly more comorbidities than outpatients. Hyposmia and hypogeusia were reported by 33% of patients and occurred significantly less frequently in hospitalized patients (12% and 13%, respectively) than in the health centers' outpatients (33% and 43%, respectively) and in the hospital outpatients (65% and 60%, respectively). Hyposmia and hypogeusia appeared more frequently after other COVID-19 symptoms. Patients with hyposmia and/or hypogeusia were significantly younger and had significantly less respiratory severity criteria than patients without these symptoms. Olfactory and gustatory dysfunction occurs frequently in COVID-19, especially in young, non-severe patients. These symptoms might be a useful tool for initial diagnostic work-up in patients with suspected COVID-19.

Infections are a frequent cause of cerebral vasculitis, important to diagnose because a specific treatment may be required. Infection-associated vasculitis can be caused by angiotropic pathogens (varicella zoster virus, syphilis, aspergillus). They can be associated with subarachnoidal meningitis (tuberculosis, pyogenic meningitis, cysticercosis). They can appear contiguously to sinuses or orbital infection (aspergillosis, mucormycosis). Finally, they also may be due to an immune mechanism in the context of chronic infections (hepatitis B virus, hepatitis C virus, human immunodeficiency virus). Cerebral vasculitis are severe conditions and their prognosis is directly linked to early recognition and diagnosis. Infectious causes must therefore be systematically considered ahead of cerebral vasculitis, and the appropriate investigations must be determined according to the patient's clinical context. We propose here an update on the infectious causes of cerebral vasculitis, their diagnosis modalities, and therapeutic options., (Copyright © 2020. Published by Elsevier Masson SAS.)

Objectives: Emerging infectious diseases are a public health issue of international concern. Identifying methods to limit their expansion is essential. We assessed the feasibility of a screening strategy in which each traveler would actively participate in the screening process after an intercontinental flight by reporting their own health status via a web-based self-administered questionnaire., Patients and Methods: In 2015 and 2017, we invited passengers arriving at or departing from Pointe-à-Pitre international airport to answer an online health questionnaire during the four days following their arrival from or at Paris-Orly international airport. SPIRE 1 was intended for passengers arriving at Pointe-à-Pitre and was conceived as a pilot study. SPIRE 2 was an improved version of SPIRE 1 and consisted in three parts, which permitted to further assess the benefits of pre-flight request and email follow-up. Endpoints were the connection rates and response rates to online health questionnaire., Results: For SPIRE 1, 4/1038 travelers (0.4%) completed the two steps of the online health questionnaire. In SPIRE 2, response rates ranged from 3/1059 (0.3%) to 19/819 (2.3%). Response rates were significantly better when passengers were approached before their flight., Conclusions: The yield of an online health questionnaire was unexpectedly low., (Copyright © 2020 Elsevier Masson SAS.

Background: Tuberculosis is associated with a risk of immune reconstitution inflammatory syndrome (IRIS) after ART initiation., Methods: Data from all patients with newly diagnosed tuberculosis disease and uncontrolled HIV infection from 1997 to 2017 in a French center were retrospectively collected. We evaluated the incidence of tuberculosis-IRIS in patients initiating ART with or without integrase inhibitors (INSTI) RESULTS: Fifty-five patients were included: 21 receiving an INSTI regimen and 34 a non-INSTI regimen. Except with regard to ART regimen, the two groups were comparable (median CD4 of 85/mm 3 ). The overall percentage of IRIS was 34% (19/55), with 52% IRIS in INSTI regimen and 23% in non-INSTI regimen respectively (P=0.04). In a multivariate logistic model, we observed an increased risk of IRIS in the INSTI regimen compared to the non-INSTI, with an OR at 3.33 [95% CI, 1.01-11.1] (P=0.05) CONCLUSIONS: ART containing integrase inhibitors could be associated with increased incidence of TB-associated IRIS., (Copyright © 2020 Elsevier Masson SAS.

Abdominal tuberculosis (ATB) is uncommon and not very well known by clinicians. We describe the characteristics, evolution, and treatment of patients with ATB in two large hospitals in the Paris region. We reviewed all records of patients treated for ATB, from January 01, 2010 to December 01, 2016, diagnosed by bacteriological and/or histological methods or highly suspected because of clinical/radiological features. We included 80 patients, with a median (IQR) age of 39 (29-50) years, with 56.2% being males. Among them, 63.7% had African origins, 15% Asian, and 11.2% European. Twenty-nine had a cause of immunosuppression ( n = 21 HIV infection). The main abdominal localizations were lymph nodes (72.5%), peritoneum (62.5%), and solid organs (25%). Extra-abdominal localizations were recorded in 65 (81.2%) patients. Tuberculosis was proven bacteriologically in 71%, histologically in 50%, and solely clinical/radiological in 10% of cases. Patients received standard therapy for a median duration of 9 months, with a favorable outcome. Corticosteroid therapy was used in 15 cases, either for paradoxical reaction or to prevent complications. Abdominal TB was mainly represented by lymphatic and peritoneal localizations, proven bacteriologically, and associated with extra-abdominal localizations in most cases. The use of steroids remains controversial, but it does not seem systematically needed in case of abdominal involvement.
