Human immunodeficiency virus type 1 (HIV-1) non-B subtype infections occurred in Belgium since the 1980s, mainly amongst migrants and heterosexuals, whereas subtype B predominated in men-having-sex-with-men (MSM). In the last decade, the diagnosis of F1 sub-subtype in particular has increased substantially, which prompted us to perform a detailed reconstruction of its epidemiological history. To this […]

The effect of primary drug resistance on CD4 cell decline and the viral load set-point in HIV-positive individuals before the start of antiretroviral therapy

OBJECTIVE: To evaluate the effect of primary resistance and selected polymorphic amino-acid substitutions in HIV reverse transcriptase and protease on the CD4 cell count and viral load set point before the start of antiretroviral treatment. DESIGN: Prospective cohort study. METHODS: A total of 6180 individuals with a resistance test prior to starting antiretroviral treatment accessing […]

HIV-1 non-B subtype infections have been observed in Belgium since the 1980s. However, subtype B predominates amongst men having sex with men (MSM), whereas other subtypes are mainly associated with sub-Saharan African migrants and heterosexual risk behavior. In the last decade, subtype F1 diagnoses have increased substantially in Belgium, representing 9% of newly diagnosed and […]

MOTIVATION: Clinicians, health officials and researchers are interested in the epidemic spread of pathogens in both space and time to support the optimization of intervention measures and public health policies. Large sequence databases of virus sequences provide an interesting opportunity to study this spread through phylogenetic analysis. To infer knowledge from large phylogenetic trees, potentially […]

International travel plays a role in the spread of HIV-1 across Europe. It is, however, not known whether international travel is more important for spread of the epidemic as compared to endogenous infections within single countries. In this study, phylogenetic associations among HIV of newly diagnosed patients were determined across Europe.
