Invasive fungal disease (IFD) in immunocompromised patients remains a major cause of morbidity and mortality and there is a pressing need for studies of novel antifungal agents and strategies to improve outcomes. Trial design details often determine not only the appropriate interpretation of the results, but also their translation into clinical practice. However, the conduct of IFD clinical trials remains challenging due to the rarity of IFD, heterogeneity of underlying diseases, and the lack of clear and standardized response criteria. Response assessments are influenced by host, underlying disease and treatment factors as well as eligibility criteria. In addition, the criteria used to assess response, when response is assessed and the type of antifungal therapy under study can impact response evaluations. This article will discuss recent trials of primary, salvage, empiric, and prophylactic antifungal therapy with specific attention to the design of these antifungal therapy trials and how their designs influence their interpretation. The potential role of surrogate markers, such as the galactomannan index, fungal deoxyribonucleic acid polymerase chain reaction assay, and (18F) fluorodeoxyglucose positron emission tomography scans in establishing the early diagnosis of IFD, as well as enhancing the ability to assess outcomes to antifungal therapy, and thereby the optimal duration of antifungal therapy, will be discussed.

Smut is a fungal disease with widespread prevalence in sugarcane planting areas. Early detection and proper identification of Sporisorium scitamineum are essential in smut management practices. In the present study, four specific primers targeting the core effector Pep1 gene of S. scitamineum were designed. Optimal concentrations of Mg(2+), primer and Bst DNA polymerase, the three important components of the loop-mediated isothermal amplification (LAMP) reaction system, were screened using a single factor experiment method and the L16(4(5)) orthogonal experimental design. Hence, a LAMP system suitable for detection of S. scitamineum was established. High specificity of the LAMP method was confirmed by the assay of S. scitamineum, Fusarium moniliforme, Pestalotia ginkgo, Helminthospcrium sacchari, Fusarium oxysporum and endophytes of Yacheng05-179 and ROC22. The sensitivity of the LAMP method was equal to that of the conventional PCR targeting Pep1 gene and was 100 times higher than that of the conventional PCR assay targeting bE gene in S. scitamineum. The results suggest that this novel LAMP system has strong specificity and high sensitivity. This method not only provides technological support for the epidemic monitoring of sugarcane smut, but also provides a good case for development of similar detection technology for other plant pathogens.
