  • Kashuba ADM, Principal Investigator. Novel Mass Spectrometry Imaging Methods to Quantify Antiretroviral Adherence. It is important to identify if someone is taking a medication regularly and as prescribed to optimize their health and wellbeing. Sometimes, patients have trouble remembering if and when they miss doses; other times, even though patients are taking their medication, it is not getting into the body in the right amount. Quickly monitoring medications in 5-10 hair strands using our novel imaging technology called IR-MALDESI will allow patients and their doctors to see how much medication they are exposed to over 1 or more months, and help identify challenges to taking medication in both research and clinical settings. This proposal will optimize and explore the acceptability and feasibility of using IR-MALDESI for monitoring medications in hair. NIH/NIAID; 01/01/2016-12/31/2020; $711,764.

  • Lewin, Principal Investigator; Kashuba ADMConsortium PI. Long term persistence of HIV in the liver and the clinical impact on HIV-HBV co-infection. One of the main challenges in the management of HIV is that it has long lived forms that persist in the face of antiviral therapy. Several studies suggest that the liver may be a reservoir of HIV even on long term ART. To determine whether HIV persistence in the liver on ART is a consequence of sub therapeutic levels of ARV in liver, as previously described for lymphoid tissue and rectal tissue, we propose to measure ARV levels in human liver, plasma and PBMC samples both pre and following at least 2 years ART by both LC-MS/MS and IR-MALDESI IMS methods.

The Clinical Pharmacology Core has recently developed and validated a sensitive, multiplex LC-MS/MS assay to measure the intracellular metabolites of the 3 most commonly prescribed NRTIs (tenofovir, emtricitabine, and lamivudine) in dried blood spots collected from patients on therapy. This assay allows investigators to monitor adherence in clinical trials with the convenience of dried blood spot sampling, storage and shipping. The addition of lamivudine, which is generically available, opens up opportunity for international investigations. Our methods and findings are in press in the Journal of Pharmaceutical and Biomedical Analysis (Schauer et al. Validation of an LC-MS/MS Assay to Simultaneously Monitor the Intracellular Active Metabolites of Tenofovir, Emtricitabine, and Lamivudine in Dried Blood Spots. JPBA. In press).

Bryan Yam


We are investigating the use of a unique IR MALDESI technology to visualize drug concentrations in hair to determine whether patients are taking their medicines as prescribed. We are having good success with this technique, but need to understand how hair products affect the amount of drug that we see.  This summer, Bryan will experience both the laboratory and clinical side of the research process.  On the clinical side, Bryan will  gain a basic understanding of the regulatory aspects of clinical research, including patient safety, confidentiality and Good Clinical Practices, as well as the daily study activities managing human subjects.  In the laboratory, Bryan will learn how our technology, blending elements of chemistry and engineering, creates images of drug response along hair strands. He will test a variety of common hair treatments on samples of hair to see how they impact the measured drug response, and will also learn about the analytical methods we use to interpret the resulting images.
