RESUMEN

Objetivo:

El síndrome de apnea obstructiva del sueño (SAOS) puede fomentar la hiperglucemia y la resistencia a la insulina. Nuestro objetivo es investigar el efecto del SAOS sobre la glucosa plasmática en ayunas, la hemoglobina glucosilada (HbA1c) y la proteína C reactiva (PCR) en pacientes no diabéticos. Material y

métodos:

Se determinaron los parámetros de analítica hemática de 90 pacientes no diabéticos consecutivos en los que se realizaron evaluaciones polisomnográficas en nuestro laboratorio del sueño. Un total de 61 de estos pacientes con una glucemia en ayunas normal fueron clasificados según el índice de apnea-hipopnea (IAH) como casos leves (n = 16, 26,2%), moderados (n = 18, 29,5%) o graves (n = 27, 44,2%) de SAOS. Se efectuaron determinaciones de la glucosa plasmática en ayunas, la HbA1c y la PCR.

Resultados:

La media de edad de los pacientes fue de 47,7 ± 11,2 años, y el 72% eran varones. Los niveles de HbA1c y de glucosa en ayunas presentan una correlación positiva con el IMC (r = 0,503, p = 0,00; r = 0,258, p = 0,045). No se detectó relación alguna de la HbA1c con el índice de apnea ni con el IAH, mientras que sí se observó una correlación positiva de la glucosa en ayunas con la PCR (r = 0,262, p = 0,042; r = 0,258, p = 0,045). Los niveles de HbA1c, glucosa en ayunas y PCR muestran una correlación negativa con los valores de SpO2 mínima (con valores de r = –0,302, p = 0,018; r = –0,368, p = 0,004; r = –0,365, p = 0,004, respectivamente). Los niveles de HbA1c, glucosa en ayunas y PCR muestran una correlación positiva con el índice de desaturación medio (tiempo durante el que la SpO2 es < 90% según la pulsioximetría) (r = 0,263, p = 0,041; r = 0,311, p = 0,015; r = 0,283, p = 0,027) (AU)
ABSTRACT

Aim:

Obstructive sleep apnea syndrome (OSAS) may promote hyperglycemia and insulin resistance. Our aim is to investigate the effect of OSAS on the fasting plasma glucose, glycosylated hemoglobin (HbA1c), and C reactive protein (CRP) in nondiabetic patients. Materials and

methods:

Blood parameters of consecutive 90 non diabetic patients whom polysomnografic evaluations were done in our sleep laboratory was evaluated. Among these 61 patients with normal fasting blood glucose were classified due to their apne-hipopnea index (AHI) as mild (n=16, 26.2%), moderate (n=18, 29.5%) and severe (n=27, 44.2%) OSAS. The fasting plasma glucose, HbA1c and CRP were measured.

Results:

Mean age of the patients was 47.7±11.2 years, 72% male. HbA1c, fasting glucose levels show positive correlation with BMI (r=0.503, P=0.00; r=0.258, P=0.045). No relation of HbA1c to apnea index nor AHI was detected while positive correlation of fasting glucose and CRP was detected (r=0.262, P=0.042; r=0.258, P=0.045). HbA1c, fasting glucose and CRP levels show negative correlation with minimum SpO2 levels (by order of r=–0.302, P=0.018; r=–0.368, P=0.004; r=–0.365, P=0.004). HbA1c, fasting glucose levels and CRP levels show positive correlation with mean desaturation index (time duration in which SpO2<90% by pulse oxymeter) (r=0.263, P=0.041; r=0.311, P=0.015; r=0.283, P=0.027).

Conclusions:

Although no relation in between increased HbA1c or glucose levels and severity of OSAS was detected in nondiabetic OSAS patients, the correlation with the night hypoxia was detected. This could also show the effect of night time hypoxia on glucose metabolism in OSAS patients (AU)
