RegaDB: Community-driven data management and analysis for infectious diseases

  • Authors: Alcantara LC, Assel M, Ayouba A, Beheydt G, Boucher C, Camacho RJ, Carvalho AP, Cavaco-Silva J, De Bel A, De Munter P, De Oliveira T, Deforche K, Ferreira F, Grossman Z, Imbrechts S, Kaiser R, Lacor P, Lapadula G, Libin P, Otelea D, Paraschiv S, Peeters M, Ruelle J, Sloot P, Snoeck J, Theys K, Torti C, Van Laethem K, Van Wijngaerden E, Vandamme AM, Wesner S, Zazzi M
  • Journal: Bioinformatics
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/23645815

RegaDB is a free and open source data management and analysis environment for infectious diseases. RegaDB allows clinicians to store, manage and analyse patient data, including viral genetic sequences. Moreover, RegaDB provides researchers with a mechanism to collect data in a uniform format and offers them a canvas to make newly developed bioinformatics tools available to clinicians and virologists through a user friendly interface.

Appearance of a single amino acid insertion at position 33 in HIV type 1 protease under a lopinavir-containing regimen, associated with reduced protease inhibitor susceptibility.

  • Authors: Camacho RJ, Detsika MG, Hatzakis A, Imbrechts S, Lazanas M, Lu L, Magiorkinis E, Magiorkinis G, Molla A, Paraskevis D, Pilot-Matias T, Van Laethem K, Vandamme AM
  • Journal: AIDS Research and Human Retroviruses

HIV drug resistance is a multifactorial phenomenon and constitutes a major concern as it results in therapy failure. The aim of this study was to assess the impact of an amino acid insertion identified at position 33 of the protease gene, derived from samples from three patients under lopinavir therapy, on viral fitness and protease inhibitor (PI) resistance.

Comparative performance of the REGA subtyping tool version 2 versus version 1

  • Authors: Abecasis AB, Camacho RJ, De Oliveira T, Imbrechts S, Libin P, Vandamme AM, Wang Y
  • Journal: Infection Genetics and Evolution
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Comparative+performance+of+the+REGA+subtyping+tool+version+2+versus+version+1

The REGA HIV-1 subtyping tool is a phylogenetic-based method for subtyping HIV-1 genomic sequences that was published in 2005. The subtyping tool combines phylogenetic approaches with recombination detection methods.
