The MDR project (HIV multidrug resistance pathways in the EuResist Integrated DataBase) aims at estimating the prevalence and trend over time of MDR (multidrug resistance) in HIV patients, using descriptive statistics, retaining high value because of the large sample size and wide representativeness of the EIDB.
In addition, the project aims at identifying factors associated with development of MDR and deriving successful treatment strategies in MDR patients, based on GSS of possible rescue therapies: these challenging and ambitious tasks will benefit from machine learning approaches and the use of probabilistic models, under the responsibility of a multidisciplinary team with excellent specific and cross-talk capability, well-established through decennial cooperation within the EuResist consortium.
The MDR project started at March 2019. The study group includes clinicians, virologists and modelers with specific strong expertise in HIV drug resistance: Dr. A. Sönnerborg (KI), Dr. M. Zazzi (UNISI), Dr. R. Kaiser (UNIKOELN), : Dr. A.M. Vandamme (Rega Institute)
The Poster "Analysis of mutational history of multi-drug resistance with a mutagenetic tree model" will be presented at the next European Meeting on HIV & Hepatitis 2022 in Paris.
Project supported by a grant from ViiV Healthcare S.r.l.
The Poster "Declining incidence of HIV multidrug resistance in Europe" has won the Best Poster Award at the 18th European AIDS Conference held Online & London, United Kingdom on October 27–30, 2021.
