Clinical, epidemiological and treatment failure data among HIV-1 non-B-infected patients in the Spanish AIDS Research Network Cohort / Datos clínicos, epidemiológicos y fracaso terapéutico en los pacientes VIH-1 infectados por variantes no-B incluidos en la Cohorte de la Red española de Investigación en Sida (CoRIS)

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

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

[Patients' understanding of the dietetic and pharmacological treatment of hypercholesterolaemia and its relationship with the achievement of objectives in patients receiving statins: OPINA study]. / Conocimiento sobre el tratamiento dietético y farmacológico de la hipercolesterolemia y su relación con el control de objetivos en pacientes que reciben estatinas: estudio OPINA.

OBJECTIVE: To evaluate the understanding of patients receiving statins about the dietary and therapeutic measures taken to control their cholesterol and to relate this to the achievement of therapy objectives. DESIGN: Transversal, multi-centre study, conducted between March and November, 2004. SETTING: Three-hundred seventy six primary care and specialist doctors from all over the country. PARTICIPANTS: A total of 2347 patients, with an average age of 59 (12) and 48% women, being treated with statins. METHOD: Survey to evaluate understanding of lipid-lowering diet and pharmacological treatment. The percentage of patients achieving therapy objectives in line with ATP III guidelines was determined. RESULTS: Understanding of diet was adequate only for foods with negative effects on the concentration of cholesterol. Overall, understanding was better in the young, those with a higher level of education, those with hyperlipaemia originating in the family, those under treatment for longer, and in those attended in primary care or internal medicine clinics; it was worse in diabetic patients and in those with cardiovascular disease. Patients with more understanding of their treatment reached their therapy objectives to a greater extent. CONCLUSION: Patients receiving statins treatment have an adequate understanding of diet, but little information on pharmacological treatment. This understanding is associated with the achievement of therapy objectives.

Conocimiento sobre el tratamiento dietético y farmacológico de la hipercolesterolemia y su relación con el control de objetivos en pacientes que reciben estatinas: estudio OPINA / Patients’ understanding of the dietetic and pharmacological treatment of hypercholesterolaemia and its relationship with the achievement of objectives in patients receiving statins: OPINA study

Objetivo. Evaluar el conocimiento de los sujetos que reciben tratamiento con estatinas sobre las medidas dietéticas y terapéuticas dirigidas a su control, relacionándolo con la consecución de objetivos terapéuticos. Diseño. Estudio transversal, multicéntrico, realizado entre marzo y noviembre de 2004. Emplazamiento. En total, 376 médicos de atención primaria y especializada distribuidos por toda la geografía nacional. Participantes. Se incluyó a 2.347 sujetos, con una edad media de 59 ± 12 años, el 48%, mujeres, y en tratamiento con estatinas. Método. Encuesta dirigida a evaluar el conocimiento sobre la dieta hipolipidemiante y el tratamiento farmacológico. Se determinó el porcentaje de sujetos que alcanzó los objetivos terapéuticos según el ATP III. Resultados. El conocimiento de la dieta era adecuado sólo para los alimentos con efectos negativos sobre la concentración de colesterol. Globalmente, el conocimiento fue mejor en los sujetos jóvenes, con un superior nivel de educación, con una hiperlipidemia de origen familiar, con más tiempo en tratamiento y que eran atendidos en consultas de atención primaria o medicina interna, y peor en los pacientes diabéticos y con enfermedad cardiovascular. Los sujetos con un mayor nivel de conocimientos sobre el tratamiento alcanzaron en mayor proporción los objetivos terapéuticos. Conclusión. Los pacientes que reciben tratamiento con estatinas tienen un adecuado conocimiento de la dieta y escasa información sobre el tratamiento farmacológico. Este conocimiento se asocia con la consecución de objetivos terapéuticos
