Popis: Introduction : Low-level viraemia (LLV) is observed in some patients with HIV-1 infection on stable antiretroviral therapy (ART). The significance of these findings remains controversial as it conflicts with traditional optimal clinic outcome. This study aims to evaluate the effect of LLV on the establishment of virological failure (VF) and immune deterioration. Methods : Retrospective observational study of a cohort of HIV-1 infected patients of an Infectious Diseases Clinic, who presented an HIV-1 viral load of 20 to 200 cp/mL, during the year 2012. Patients who were not on ART or non-adherent in the previous 6 months were excluded. Compliance was quantified by clinical and pharmaceutical records. Adherence was defined as ≥95% compliance rate. Demographic, clinical, immunological and therapeutic data were collected from clinical records. LLV was defined as a range of 20–200 cp/mL and stratified as transient (T-LLV): only one measurement, persistent (P-LLV): 2 consecutive measurements with an interval ≥3 months and recurrent (R-LLV): ≥1 T-LLV during an 18-month follow-up. Statistical analysis was performed with Microsoft Office ® – Excel 2012. Kolmogorov – Smirnov test, t -test and chi-square test were performed for a significant p value
