Trichophyton mentagrophytes ITS genotype VII infections among men who have sex with men in France: An ongoing phenomenon.
Article in Journal of the European Academy of Dermatology and Venereology : JEADV, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 22 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTrichophyton mentagrophytes ITS genotype VII (TMVII) has recently been identified in France as the causative agent of dermatophyte infections transmitted during sexual activity among men who have sex with men (MSM).
objectivesOur objective was to provide new insights into the epidemiology, clinical presentation and treatment of TMVII infections based on cases diagnosed from October 2022 to September 2023 in three medical mycology laboratories in Paris. Additionally, we aimed to perform molecular characterization of TMVII strains collected in Paris, as well as in Switzerland.
methodsWe identified all isolates from skin and hair belonging to the T. mentagrophytes complex by sequencing the ITS region. For isolates corresponding to TMVII, clinical data were retrieved from medical records. For all available TMVII strains that we isolated since January 2021, we sequenced tef1α and tubb and determined the MAT locus idiomorph.
resultsWe identified 32 cases of TMVII Infections. All cases occurred in men, 30 of whom reported having sex with men. Fifteen cases were sporadic cases including four among sex workers. The other 17 cases belonged to a single cluster involving a tantric masseur who infected 15 clients and his roommate. The median time from massage to lesion onset was 16 [2-52] days. Except for one patient, all other patients received systemic antifungal treatment with terbinafine. We observed five patients whose cultures remained positive even after 3-4 weeks of treatment and five patients experienced a relapse of the infection after discontinuing antifungal treatment. All French isolates exhibited identical tef1α and tubb sequences, as well as the same MAT idiomorph locus. They displayed variations in the tef1α sequence compared to isolates from Switzerland and the Czech Republic.
conclusionsWe confirm the active circulation of TMVII among MSM in France, which is associated with challenges in diagnosis, treatment and prevention.
