ABSTRACT

Aim:

to evaluate the serum concentration of NO in overweight women, smokers (SG) and nonsmokers (NSG).

Methods:

blood samples from smokers (n = 20) and nonsmokers (n = 18) were collected to obtain serum, and stored at -80 ºC until analysis. NO was assessed by measuring total nitrite, determined by Greiss method. It was adopted as reference 24.4 µmol/L, mean value found in a study with healthy subjects without excess weight. We used the Student t test to compare the means of age and waist circumference, and the Mann-Whitney U test to compare the median of concentrations of nitrite, number of cigarettes/day and Body Mass Index. We adopted a significance level of p<0.05.

Results:

the median nitrite in SG was 16.53 (2.79 - 69.72) µmol/L, whereas in NSG was 10.85 (1.44 - 43.25) µmol/L (p = 0.028). BMI median value to SG and NSG, was respectively 29.50 (25.00 - 38.14) kg/m2 and 30.68 (25.10 - 36.98) kg/m2 (p = 0.530), being classified as overweight. The data showing that the average nitrite was below the estimated value for healthy individuals.

Conclusion:

the results indicate a decrease of NO metabolites in women with excess weight, independently of being smoker. Despite the significant difference found between groups, these women had values well below the reference value of NO for healthy women. Therefore, it seems that smoking does not interfere in nitrite levels in patients already compromised by obesity (AU)
RESUMEN

Objetivo:

evaluar la concentración sérica de NO en las mujeres con sobrepeso, fumadoras (SG) y no fumadoras (GSN).

Método:

se recogieron muestras de sangre de las fumadoras (n = 20) y no fumadoras (n = 18) para obtener el suero, y se almacenaron a -80 °C hasta su análisis. NO se evaluó mediante la medición total de nitrito, determinado por el método Greiss. Fue adoptado como referencia de 24,4 µmol/L, valor medio que se encuentra en un estudio con sujetos sanos sin exceso de peso. Se utilizó la prueba t de Student para comparar las medias de edad y la circunferencia de la cintura, así como la prueba de Mann-Whitney para comparar la mediana de las concentraciones de nitrito, número de cigarrillos/día y el Índice de Masa Corporal. Hemos adoptado un nivel de significación de p<0.05.

Resultados:

la mediana de SG nitrito fue 16,53 (2,79- 69,72) mol/L, mientras que en NSG fue 10,85 (1,44-43,25) µmol/L (p = 0,028). El IMC valor de la mediana de SG y NSG fue, respectivamente, 29,50 (25,00-38,14) kg/m2 y 30,68 (25,10-36,98) kg/m2 (p = 0,530), siendo clasificado como sobrepeso. Los datos muestran que el nitrito promedio estuvo por debajo del valor estimado para individuos sanos.

Conclusiones:

los resultados indican una disminución de los metabolitos NO en las mujeres con exceso de peso, independientemente de si son fumadoras o no. A pesar de la diferencia significativa entre los grupos, estas mujeres tenían valores muy por debajo del valor de referencia del NO para las mujeres sanas. Por lo tanto, parece que el fumar no interfiere en los niveles de nitritos en pacientes que ya están comprometidas por la obesidad (AU)
