There are no standard choices on antifungal drugs for talaromycosis due to various factors, and related studies are also limited. This study summarizes and analyzes efficacy of different antifungal drugs for patients with talaromycosis, which can provide more reference evidence for drugs' choices in practice. We conducted a meta-analysis on prognostic impacts of different antifungal drugs against talaromycosis, and primary outcome was all-cause mortality. ⋯ Initial treatment with amphotericin B for talaromycosis in different regions (internal and external) and studies (sample size<100) had no obvious prognostic advantages over itraconazole (RR: 0.60, 95% CI: 0.32-1.13; P=0.11; I2=44%; RR: 0.61, 95% CI: 0.37- 1.00; P=0.05; I2=0%; RR: 0.71, 95% CI: 0.39-1.29; P=0.26; I2=0%, respectively). However, when study's sample size was ≥ 100, the mortality of amphotericin B group was significantly reduced (RR: 0.54, 95% CI: 0.32- 0.92; P=0.02; I2=46%). In conclusion, amphotericin B is a better choice as initial therapeutic drug for talaromycosis.

As aspergillosis is a well-known complication of severe influenza, we suggest that SARS-CoV-2 might be a risk factor for invasive aspergillosis (IA). We report the case of an 87 year-old woman, with no history of immune deficit, admitted in our emergency room for severe respiratory distress. Coronavirus disease 2019 (COVID-19) diagnosis was confirmed by a SARS-CoV-2 reverse transcriptase polymerase chain reaction (PCR) on nasal swab. ⋯ Considering SARS-CoV-2 acute respiratory distress syndrome (ARDS) as an acquired immunodeficiency, we report here a new case of "probable" IA based on clinical and biological arguments, in accordance with the last consensus definition of invasive fungal disease. On a routine basis, we have detected 30% of aspergillosis carriage (positive culture and antigen in tracheal secretions) in critically ill patients with COVID-19 in our centre. Further studies will have to determine whether sputum or tracheal secretions should be systematically screened for fungal investigations in intensive care unit (ICU) COVID-19 patients to early diagnose and treat aspergillosis.

Invasive pulmonary aspergillosis in an ICU patient with Legionnaires' disease: A diagnostic challenge.
Aspergillus fumigatus can cause a wide range of diseases, from hypersensitivity to invasive infection. Invasive disease usually occurs in severely immunocompromised patients with deep and prolonged neutropenia. ⋯ In addition to commonly accepted risk factors for IPA in ICU patients, we hypothesis that L. pneumophilia pneumonia could enhance this type of infection. We also reviewed all published cases of coinfection with L. pneumophila and A. fumigatus to assess whether Legionnaires' disease could be a risk factor for IPA.

Chromoblastomycosis is defined as a chronic cutaneous and subcutaneous fungal infection caused by melanized or brown-pigmented fungi. A 63-year-old man farmer showed on external and internal part of the right arm, a well-delimited verrucous and hyperkeratotic plaque, with atrophic and cicatricial areas. Direct examination of skin scrapings samples showed the presence of muriform cells, a classic feature of chromoblastomycosis. ⋯ Fonsecaea pedrosoi was identified from paraffin-embedded skin samples and fungal colonies. A combined therapy with terbinafine and itraconazole, plus cryotherapy was applied with an important improvement. Herein, we report an impressive case of chromoblastomycosis due to Fonsecaea pedrosoi with a successful outcome.
