BACKGROUND: Estimation of temporal changes in human immunodeficiency virus (HIV) transmission patterns can help to elucidate the impact of preventive strategies and public health policies. METHODS: Portuguese HIV-1 subtype B and G pol genetic sequences were appended to global reference data sets to identify country-specific transmission clades. Bayesian birth-death models were used to estimate subtype-specific […]

Drivers of HIV-1 transmission: The Portuguese case

  • Autores: Pineda-Peña AC, Pingarilho M, Li G, Vrancken B, Libin P, Gomes P, Camacho RJ, Theys K, Abecasis AB, Portuguese Hiv-1 Resistance Study Group
  • Ano de Publicação: 2019
  • Journal: PLoS One
  • Link: https://www.ncbi.nlm.nih.gov/pubmed/31568476

BACKGROUND: Portugal has one of the most severe HIV-1 epidemics in Western Europe. Two subtypes circulate in parallel since the beginning of the epidemic. Comparing their transmission patterns and its association with transmitted drug resistance (TDR) is important to pinpoint transmission hotspots and to develop evidence-based treatment guidelines. METHODS: Demographic, clinical and genomic data were […]

HIV-1 Infection in Cyprus, the Eastern Mediterranean European Frontier: A Densely Sampled Transmission Dynamics Analysis from 1986 to 2012

  • Autores: Pineda-Peña AC, Kostrikis LG, Stylianou DC, Demetriades I, SPREAD/ESAR Program, Abecasis AB, Theys K
  • Ano de Publicação: 2018
  • Journal: Scientific Reports
  • Link: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5786036/

Since HIV-1 treatment is increasingly considered an effective preventionstrategy, it is important to study local HIV-1 epidemics to formulate tailored preventionpolicies. The prevalence of HIV-1 in Cyprus was historically low until 2005. To investigatethe shift in epidemiological trends, we studied the transmission dynamics of HIV-1 in Cyprususing a densely sampled Cypriot HIV-1 transmission cohort that […]

Epidemiological history and genomic characterization of non-D1 HBV strains identified in Iran

  • Autores: Alavian SM, Amini-Bavil-Olyaee S, Faria NR, Lemey P, Maes P, Mina T, Pineda-Peña AC, Pourkarim MR, Van Ranst M

Hepatitis B virus (HBV) has been classified into eight genotypes and forty subgenotypes. Genotype D of HBV is the most worldwide distributed genotype and HBV subgenotype D1 has been isolated from Iranian patients. To characterize for the first time complete genomes of recently emerged non-D1 strains in Iran. HBV complete genomes isolated from 9 Iranian […]

CRF19_cpx is an Evolutionary fit HIV-1 Variant Strongly Associated With Rapid Progression to AIDS in Cuba

  • Autores: Abrahantes Y, Aleman Y, Khouri R, Kourí V, Megens S, Moutschen M, Pérez AB, Perez J, Perez L, Pfeifer N, Pineda-Peña AC, Theys K, Van Laethem K, Van Weyenbergh J, Vandamme AM, Vercauteren J

  • Link: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4484819/%20

Clinicians reported an increasing trend of rapid progression (RP) (AIDS within 3 years of infection) in Cuba. Recently infected patients were prospectively sampled, 52 RP at AIDS diagnosis (AIDS-RP) and 21 without AIDS in the same time frame (non-AIDS). 22 patients were sampled at AIDS diagnosis (chronic-AIDS) retrospectively assessed as > 3 years infected. Clinical, demographic, virological, epidemiological […]
