Investigation
Exposure and response relationship in antifungal treatment
Research Lines
Content with Investigacion .
The prophylactic and empirical use of antifungal agents in general, and azoles and echinocandins in particular, has contributed to the emergence of strains with elevated MICs (microbiological resistance), whose clinical impact and relevance are increasingly concerning. Moreover, therapeutic failure or clinical resistance is frequently observed even in the absence of microbiological resistance.
One of the factors that may explain clinical resistance in the absence of microbiological resistance is inadequate drug exposure at the site of infection, together with the pathogen’s adaptive response to host defences or to the administered antifungal therapy.
This research line, active since 2010, aims to advance the understanding of clinical resistance in Aspergillus fumigatus infection through the study of antifungal dose–response relationships by evaluating PK/PD parameters and their role in treatment efficacy. In addition, it investigates the role of biofilms as adaptive strategies that enhance fungal resistance to antifungal agents and to host immune cells.
Exposure: Pharmacokinetics of Antifungal Agents
There is now substantial evidence that the administration of an effective antifungal agent at the appropriate dose is essential to achieve adequate drug concentrations at the site of infection. Through the development of this research line (active since 2009), our group has gained extensive expertise in the development and application of chromatographic methods (HPLC/UPLC–UV/fluorescence) for antifungal quantification, which are useful for therapeutic drug monitoring (TDM).
Techniques that allow monitoring of blood drug concentrations constitute essential tools in patient management, enabling dose optimization by determining whether drug exposure is inadequate—potentially contributing to therapeutic failure and the emergence of resistance—or, conversely, excessive, thereby increasing the risk of significant toxicity.
In addition, the application of disciplines such as pharmacogenetics to antifungal therapy is promoting personalized treatment approaches and improving the management of severe invasive fungal infections (IFIs).
The use of alternative animal models, with ethical approval and under regulatory frameworks, together with methodological advances, has facilitated the preliminary study of dose–response relationships for both established antifungal agents and newly developed compounds.
Response: Monitoring Treatment Efficacy
An aspect of major relevance in the management of severe invasive fungal infections (IFIs) is the evaluation of the efficacy of the administered therapy. This research line further explores the characterization of circulating fungal-specific biomarkers that may help distinguish infection from fungal colonization and assess the effectiveness of the established treatment.
Within this framework, our efforts have focused on the study and characterization of compounds related to fungal secondary metabolism, such as gliotoxin and its derivative bis(methylthio)gliotoxin, detected in tissue and blood samples from patients with aspergillosis and in animal models, as well as other metabolites associated with fungal virulence (e.g., fumagillin and pseurotin A).
More recently, this research line has expanded to investigate adaptive strategies such as the formation of complex biofilm structures—often multispecies in nature and involving intricate interaction mechanisms—which may explain fungal resistance to antifungal agents and host immune cells, thereby contributing to therapeutic failure (clinical resistance).

Alicia Gómez López
Research Scientist
ORCID code: 0000-0003-2780-5039
Doctor of Pharmacy from the Complutense University of Madrid and specialist in Microbiology and Parasitology via FIR (La Paz Hospital, Madrid). He completed his doctoral thesis at the Reference and Research Laboratory in Mycology under the supervision of Manuel Cuenca-Estrella. Currently a career civil servant in the Scientific Scale of O.P.I. at the Reference and Research Laboratory in Mycology.
Since 2010, he has been leading a line of research that seeks to advance clinical resistance in fungal infection through the study of dose/response relationships, the evaluation of PK/PD parameters of antifungals and their role in efficacy, as well as the study of biofilms as strategies that favour the resistance of fungal cells to the action of antifungals and immune cells. This line of research has resulted in the development and application of chromatographic methods (UPLC-UV) for antifungal monitoring and the characterisation of fungal biomolecules indicative of infection progression, which are useful for evaluating treatment response and diagnosis. Some of these methodologies have been validated according to protocols defined by the EMA and have been recognised by ENAC as valid methods for monitoring azoles in clinical samples. They are currently part of LRIM's portfolio of services and are in high demand as this methodology is not always available in clinical laboratories.
This line of research has been active since 2009, with continuous funding through various competitive calls from the AES as well as other collaborative private funding projects (9 Research Projects as IP in the period 2010-2025, Strategic Action in Health, AES FIS-ISCIII, calls for proposals 2009, 2013, 2016, 2021 and 2025; 22 research projects leading/collaborating in experimental or technological developments in the period 2000-2025).

In 2016, she completed a Postgraduate Diploma in Promotion and Management of International Projects (Technical University of Madrid) and undertook a research stay at the Microbiology and Infection Research Domain, Life and Health Sciences Research Institute (ICVS), School of Health Sciences, University of Minho (Braga, Portugal). She was subsequently appointed as a PhD researcher within the Biomedical Research Networking Center in Infectious Diseases (CIBERINFEC). Since 2024, she serves as Specialist Scientist at the Carlos III Health Institute (ISCIII) and is responsible for the Diagnostic and Serology Section for Endemic Fungi at the Mycology Reference and Research Laboratory.
Dr. Bernal-Martínez has authored more than 30 peer-reviewed scientific publications and two book chapters. She has actively participated in over 12 research projects and has presented her work at numerous national and international scientific conferences. Her research has focused on human fungal infections, antifungal resistance, therapeutic drug monitoring, genetic variants associated with antifungal metabolism, and the identification of predictive biomarkers of invasive fungal infections. However, her primary expertise lies in the diagnostic field, particularly in the design, optimization, and validation of real-time PCR–based methodologies.
She is currently Principal Investigator of a research project aimed at improving current diagnostic techniques for invasive fungal infections, evaluating emerging diagnostic technologies, and studying primary fungal pathogens. A substantial part of her work has been transferred to the Spanish National Health System and to research centers in Latin America. Many of the diagnostic methodologies developed have been incorporated into the official service portfolio of ISCIII. She has collaborated with multiple hospitals through research projects and clinical trials applying these technologies, as well as with the ISCIII spin-off company Micomol S.L.
Dr. Bernal-Martínez has supervised several Master’s and Undergraduate Final Degree Projects from students at the Complutense University of Madrid and the University of Alcalá. She is a member of the teaching staff of the UNED-ISCIII PhD Program in Biomedical Sciences and Public Health and serves as lecturer in the Master’s Program in Public Health and Research in Infectious Diseases at the University of Alcalá.
