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

Abstract Background Patients with suspected Middle East respiratory syndrome coronavirus (MERS-CoV) infection should be hospitalized in isolation wards to avoid transmission. This suspicion can also lead to medical confusion and inappropriate management of acute respiratory syndrome due to causes other than MERS-CoV. Methods We studied the characteristics and outcome of patients hospitalized for suspected MERS-CoV infection in the isolation wards of two referral infectious disease departments in the Paris area between January 2013 and December 2016. Results Of 93 adult patients (49 male (52.6%), median age 63.4 years) hospitalized, 82 out of 93 adult patients had returned from Saudi Arabia, and 74 of them were pilgrims (Hajj). Chest X-ray findings were abnormal in 72 (77%) patients. The 93 patients were negative for MERS-CoV RT-PCR, and 70 (75.2%) patients had documented infection, 47 (50.5%) viral, 22 (23.6%) bacterial and one Plasmodium falciparum malaria. Microbiological analysis identified Rhinovirus (27.9%), Influenza virus (26.8%), Legionella pneumophila (7.5%), Streptococcus pneumoniae (7.5%), and non-MERS-coronavirus (6.4%). Antibiotics were initiated in 81 (87%) cases, with two antibiotics in 63 patients (67.7%). The median duration of hospitalization and isolation was 3 days (1–33) and 24 h (8–92), respectively. Time of isolation decreased over time (P

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.
