ABSTRACT

INTRODUCTION:

The prevalence of HIV-1 non-B variants is increasing in Spain, showing a higher number of transmitted drug resistance mutations (TDR) since 2002. This study presents the features of non-B-infected patients enrolled in the cohort of antiretroviral treatment (ART) naïve HIV-infected patients included in the Research Network on HIV/AIDS (CoRIS).

METHODS:

The study includes a selected group of HIV-1 non-B-infected subjects from 670 subjects with pol sequences collected from 2004 to 2008 in the CoRIS cohort. Epidemiological-clinical-virological data were analyzed since cohort entry until October 2011, considering the presence or absence of treatment failure (TF).

RESULTS:

Eighty two non-B infected subjects with known HIV-1 variants were selected from 2004 to 2008 in the CoRIS cohort, being mainly female, immigrants, infected by recombinant viruses, and by heterosexual route. They had an intermediate TDR rate (9.4%), a high rate of TF (25.6%), of losses to follow-up (35%), of coinfections (32.9%), and baseline CD4+ counts ≥350 cells/mm3 (61.8%). Non-B subjects with TF showed higher rates of heterosexual infection (85.7% vs. 69.5%, p < 0.05), tuberculosis (30.8%vs. 9.1%, p = 0.10) and hepatitis C (23.8% vs. 13.9%, p = 0.34) coinfections and lower rates of syphilis (0% vs. 21.9%, p < 0.05), and had more frequently received first-line ART including protease inhibitors (PIs) than patients without TF (70% vs. 30%, p < 0.05). Interestingly, infection with non-B variants reduced the risk of TDR to nucleoside reverse transcriptase inhibitors and increased the risk to PIs.

CONCLUSION:

HIV-1 non-B-infected patients in Spain had a particular epidemiological and clinical profile that should be considered during their clinical management
RESUMEN

INTRODUCCIÓN:

La prevalencia de variantes no-B del VIH-1 está aumentando en España, mostrando un incremento de las mutaciones de resistencia transmitidas (TDR) desde 2002. Este estudio muestra las características de los pacientes infectados por variantes no-B de la cohorte de infectados por VIH sin tratamiento antirretroviral de la Red de Investigación sobre VIH/SIDA (CoRIS).

MÉTODOS:

De 670 individuos en CoRIS con secuencias pol recogidas entre 2004 y 2008, se seleccionaron los pacientes infectados por variantes no-B. Se analizaron los datos epidemiológicos, clínicos y virológicos desde su inclusión hasta octubre de 2011, considerando la existencia de fracaso terapéutico (FT).

RESULTADOS:

Los 82 pacientes infectados por variantes no-B entre 2004 y 2008 fueron principalmente mujeres, inmigrantes, infectados por variantes recombinantes y transmisión heterosexual. Presentaron una tasa intermedia de TDR (9,4%) y elevada frecuencia de FT (25,6%), pérdidas de seguimiento (35%), coinfecciones (32,9%) y recuento basal de CD4+ ≥350 células/mm3 (61,8%). Los pacientes no-B con FT vs. sin FT mostraron mayor porcentaje de transmisión heterosexual (85,7% vs. 69,5%, p < 0,05), coinfecciones por tuberculosis (30,8% vs. 9,1%, p = 0,10), hepatitis C (23,8% vs. 13,9%, p = 0,34) y menores tasas de sífilis (0% vs. 21,9%, p < 0,05). Además recibieron con mayor frecuencia tratamiento de primera línea con inhibidores de la proteasa (IP) (70% vs. 30%, p < 0,05). La infección con variantes no-B redujo el riesgo de TDR a inhibidores de la transcriptasa inversa análogos de nucleósido y aumentó el riesgo a IP.

CONCLUSIÓN:

Los pacientes infectados por variantes no-B del VIH-1 en España presentan un perfil epidemiológico-clínico característico que deberá ser considerado durante su seguimiento
