Abstract
Backgroud and objectives

As patients with diabetes are at a significantly higher risk of cardiovascular diseases than those without diabetes, it is important to gain a clinical understanding of the differential effects of smoking cessation on several risk factors between patients with and without diabetes.

Materials and methods

Patients who participated in a smoking cessation program received an assessment of the outcomes of interest. The outcomes were changes in metabolic parameters and renal function from baseline to 6-month follow-up after the smoking cessation program.

Result

A total of 1954 patients joined the smoking cessation program, and 1381 patients were in the smoking cessation failure (SCF) group and 573 were in the smoking cessation success (SCS) group. The decrease in HbA1c after smoking cessation was only observed in patients with diabetes. Smoking cessation was also associated with a significant decrease in LDL cholesterol in patients with diabetes. In terms of renal function, smoking cessation was associated with an improvement in eGFR, and the trend was similar in patients with and without diabetes.

Conclusion

Successful smoking cessation was associated with improvement in renal function. Moreover, it was associated with improvements in HbA1c and LDL cholesterol in patients with diabetes, despite significant weight gain.

Resumen
Antecedentes y objetivos

Dado que los pacientes con diabetes tienen un riesgo significativamente mayor de sufrir enfermedades cardiovasculares que aquellos sin diabetes, es importante obtener una comprensión clínica de los efectos diferenciales de dejar de fumar sobre varios factores de riesgo entre pacientes con y sin diabetes.

Materiales y métodos

Los pacientes que participaron en un programa para dejar de fumar recibieron una evaluación de los resultados de interés. Los resultados fueron cambios en los parámetros metabólicos y la función renal desde el inicio hasta el seguimiento de 6 meses después del programa para dejar de fumar.

Resultado

Un total de 1.954 pacientes se unieron al programa para dejar de fumar, 1.381 pacientes estaban en el grupo de fracaso para dejar de fumar (SCF) y 573 estaban en el grupo de éxito para dejar de fumar (SCS). La disminución de la HbA1c tras dejar de fumar sólo se observó en pacientes con diabetes. Dejar de fumar también se asoció con una disminución significativa del colesterol LDL en pacientes con diabetes. En términos de función renal, dejar de fumar se asoció con una mejora en la TFGe, y la tendencia fue similar en pacientes con y sin diabetes.

Conclusión

Dejar de fumar exitosamente se asoció con una mejora en la función renal. Además, se asoció con mejoras en la HbA1c y el colesterol LDL en pacientes con diabetes, a pesar de un aumento de peso significativo.
