The Stanford HIV Resistance Database is a comprehensive resource that tracks and analyzes the emergence of HIV resistance to antiretroviral therapies. Established in 1998, the database has become a crucial tool for researchers, clinicians, and public health officials to monitor and understand the evolving landscape of HIV drug resistance. As a repository of HIV-1 genomic sequences and associated clinical data, the Stanford database provides valuable insights into the molecular mechanisms underlying resistance development and the impact of resistance on treatment outcomes.
Understanding HIV Resistance
HIV resistance occurs when the virus mutates in response to the selective pressure exerted by antiretroviral drugs, leading to a reduction in the effectiveness of these therapies. The development of resistance is a major concern in the management of HIV infection, as it can compromise treatment efficacy and limit treatment options. The Stanford HIV Resistance Database plays a critical role in addressing this challenge by providing a centralized platform for the collection, analysis, and dissemination of resistance data.
The database contains a vast array of genotypic and phenotypic data, including HIV-1 genomic sequences, drug resistance mutations, and clinical information such as treatment regimens and viral load measurements. By analyzing these data, researchers can identify patterns and trends in resistance emergence, inform the development of new antiretroviral therapies, and optimize treatment strategies to minimize the risk of resistance.
Key Features of the Stanford HIV Resistance Database
The Stanford database is distinguished by its comprehensive and curated dataset, which is updated regularly to reflect the latest advances in HIV research and treatment. Some of the key features of the database include:
- A large and diverse collection of HIV-1 sequences, representing a wide range of viral subtypes and circulating recombinant forms
- A standardized system for annotating resistance mutations, ensuring consistency and accuracy in the interpretation of genotypic data
- A user-friendly interface for querying and analyzing data, enabling researchers to easily explore the database and extract relevant information
