RESUMO

Hypoxia is involved in the development of chronic inflammatory processes. Under hypoxic conditions HIF1A, VEGF and VEGFR2 are expressed and mediate the course of the resultant disease. The aim of the present study was to define the associations between tSNPs in these genes and COPD susceptibility and progression in a Spanish cohort. The T alleles in rs3025020 and rs833070 SNPs (VEGFA gene) were less frequent in the group of COPD cases and were associated with a lower risk of developing the disease (OR = 0.60; 95% CI = 0. 39-0.93; p = 0.023 and OR = 0.60; 95% CI = 0.38-0.96; p = 0.034, respectively) under a dominant model of inheritance. The haplotype in which both SNPs presented the T allele confirmed the association found (OR = 0.02; 95% CI = 0.00 to 0.66; p = 0.03). Moreover, patients with COPD carrying the T allele in homozygosis in rs3025020 SNP showed higher lung function values and this association remained constant during 3 years of follow-up. In conclusion, T allele in rs833070 and rs3025020 may confer a protective effect to COPD susceptibility in a Spanish population and the association of the SNP rs3025020 with lung function may be suggesting a role for VEGF in the progression of the disease.

RESUMO

Determinar la concordancia entre las escalas PROCAM (Prospective Cardiovascular Münster) y Framingham en pacientes receptores de tratamiento antirretroviral. Materiales y métodos. Estudio transversal analítico en población masculina VIH positiva que recibe tratamiento antirretroviral en un hospital de referencia nacional en Lima, Perú. Para evaluar la concordancia entre ambas escalas se empleó el método gráfico de Bland y Altman, correlación con el coeficiente de Pearson y acuerdo entre pruebas mediante el coeficiente de Kappa. Resultados. Enrolamos 111 personas, con edad promedio de 47,0 años. La distribución de pacientes en riesgo cardiovascular bajo, moderado y alto fue de 81,2%, 13,6% y 5,4%, según PROCAM y de 71,2%, 25,2% y 3,6% según Framingham, respectivamente. Según el método de Bland y Altman, la concordancia fue adecuada en valores bajos y se fue perdiendo en riesgos altos. El coeficiente de Pearson mostró fuerte correlación (r=0,87 y p<0,05) y el coeficiente de Kappa fue de 0,56 (p<0,001). Conclusiones. La concordancia existente a riesgos bajos se va perdiendo a medida que el riesgo se va incrementando. Existe fuerte correlación entre ambas escalas. Se recomienda realizar más estudios que permitan conocer qué escala es la más óptima para ser utilizada en población adulta VIH positiva que recibe tratamiento antirretroviral...


Objectives. The aim of the study is to determine the concordance between the PROCAM (Prospective Cardiovascular Münster) and Framingham scales in patients receiving highly active antiretroviral therapy (HAART). Materials and methods. A cross sectional study was conducted in HIV-positive male population who use HAART in a national reference hospital located in Lima, Peru. To evaluate the concordance between the two scales the graphic method of Bland and Altman was used, for the evaluation of the correlation we used the Pearson coefficient and to measure the agreement we use the kappa coefficient. Results. 111 patients were enrolled, with an average age of 47.0 years. The distribution of patients according to the risk was low, moderate and high, 81.2%, 13.6% and 5.4% respectively for PROCAM and 71.2%, 25.2% and 3.6% for Framingham. According to the graphic method of Bland and Altman, the concordance was adequate in low values and was lost as the risk score increased. PearsonÆs test found a strong correlation (r=0.87 and p<0.05) and the kappa coefficient was 0.56 (p<0,001). Conclusions. The agreement we found at low risk decreases as the risk increases. Strong correlation was found between the two scales. We recommend further studies in order to know which scale of cardiovascular risk is the most optimal scale for clinical practice among HIV population who receive HAART...

RESUMO

OBJECTIVES: The aim of the study is to determine the concordance between the PROCAM (Prospective Cardiovascular Münster) and Framingham scales in patients receiving highly active antiretroviral therapy (HAART). MATERIALS AND METHODS: A cross sectional study was conducted in HIV-positive male population who use HAART in a national reference hospital located in Lima, Peru. To evaluate the concordance between the two scales the graphic method of Bland and Altman was used, for the evaluation of the correlation we used the Pearson coefficient and to measure the agreement we use the kappa coefficient. RESULTS: 111 patients were enrolled, with an average age of 47.0 years. The distribution of patients according to the risk was low, moderate and high, 81.2%, 13.6% and 5.4% respectively for PROCAM and 71.2%, 25.2% and 3.6% for Framingham. According to the graphic method of Bland and Altman, the concordance was adequate in low values and was lost as the risk score increased. Pearson’s test found a strong correlation (r=0.87 and p<0.05) and the kappa coefficient was 0.56 (p<0,001). CONCLUSIONS: The agreement we found at low risk decreases as the risk increases. Strong correlation was found between the two scales. We recommend further studies in order to know which scale of cardiovascular risk is the most optimal scale for clinical practice among HIV population who receive HAART.
