Also, we want to evaluate the causes of the increased number of cases of sporotrichosis in the pediatric population such as environmental changes in endemic areas, the biodiversity, and virulence among the pathogenic clade causing sporotrichosis in different areas of the globe, and especially the progression of the zoonotic transmission of infections caused by <i>Sporothrix brasiliensis</i> infections, associated to zoonotic transmission in Brazil and other endemic sporotrichosis countries.</p><p><strong>Recent findings: </strong>After evaluating a case series of 40 patients, we found that pediatric sporotrichosis in Mexico is mainly caused by <i>Sporothrix schenckii</i> which prevails in rural areas and is mainly sapronotically transmitted. In Brazil, the longest and largest pediatric sporotrichosis outbreak is caused by <i>Sporothrix brasiliensis</i>, etiologically related to sick cats, directly from lesions containing a high yeast cell burden. When affecting children <i>S. schenckii</i> and <i>S. brasiliensis</i> may cause distinct clinical manifestations especially in the onset of the disease and affected anatomical site. In Mexico, most of the patients are successfully treated with potassium iodide, whereas in Brazil, all patients respond to itraconazole.</p><p><strong>Summary: </strong><i>Sporothrix schenckii</i> is the major etiologic agent in Mexico, being sapronotically transmitted, while in Brazil, <i>Sporothrix brasiliensis</i> is only transmitted by cats. In Mexico, the disease prevails in male patients (60%) from rural areas; in Brazil, the disease is more frequent in females (60%) from an urban region. Due to the zoonotic sporotrichosis outbreak in Brazil, the time of evolution seems to be shorter in Brazilian patients than in Mexican patients. Most Brazilian patients presented with facial lesions, including ocular involvement, while in Mexico, most of the children presented upper limbs involvement. In Mexico, treatment with potassium iodide in children was observed to induce faster remission than itraconazole, but controlled studies are lacking to evaluate this versus itraconazole, due to the low number of cases. A comparative study should be designed to evaluate the best and safest antifungal therapy for pediatric sporotrichosis.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s12281-022-00429-x.</p>","PeriodicalId":10813,"journal":{"name":"Current Fungal Infection Reports","volume":"16 2","pages":"33-46"},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8902271/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9178690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Systemic glucocorticoids are a double-edged sword, on the one hand, life-saving in treating COVID-19 complications while on the other hand, potentially leading to life-and-limb-threatening opportunistic fungal infections. Mucormycosis (MM) is caused by the mucormycetes family. Although rare, it is characterized by high mortality and significant morbidity. The gross similarities observed with other fungal infections which respond to different treatment regimens have made it all the more imperative to quickly and sensitively diagnose and treat MM. This review discusses the epidemiology of MM before and during the COVID-19 pandemic, associated risk factors, COVID-19-associated MM, diagnosis, and current therapeutic interventions.</p><p><strong>Recent findings: </strong>There has been a widespread and worrisome trend of rising in cases of MM, worldwide, but more so in the Indian subcontinent, where it is nicknamed the \"black fungus.\" This upsurge has picked up the pace ever since the start of the COVID-19 pandemic. Necrosis is secondary to the angio-invasive and pro-thrombotic nature of the mold resulting in extensive lesions presenting mostly as rhino-orbital MM (ROM) and rhino-orbito-cerebral MM (ROCM). Infection is mostly observed in subjects with underlying risk factors such as uncontrolled diabetes, those receiving hematopoietic stem cell transplant, and/or on corticosteroid or immunosuppressive therapy, although it is widely suspected that other factors such as iron and zinc may play a role in the pathogenesis of MM. The \"One world one guideline\" strategy advocates both prophylactic anti-fungal therapy along with aggressive, prompt, and individualized treatment with anti-fungal drugs such as amphotericin B in addition to vigorous surgical intervention. High-risk groups need particularly rapid diagnosis although empirical anti-fungal therapy may not be delayed. Speeding diagnostic turnaround times are essential to institute early therapy, and there is much scope for newer modalities such as PCR, matrix-assisted laser desorption ionization-time of flight mass spectrometry, and whole-genome sequencing in such endeavors. The results of strict monitoring of blood glucose levels along with rational and limited use of steroids and immunomodulatory drugs have proven to be a significant preventive measure.</p><p><strong>Summary: </strong>The significant rise in cases of MM worldwide has necessitated viewing each case with a strong index of suspicion. Adoption of rapid diagnostics, early antifungal therapy, and prompt surgical interventions are essential, while high-risk groups need particular focused care which may include prophylactic anti-fungal therapy, limited steroid use, and meticulous control of the underlying disease.
