Abstract

Introduction: Obesity is a gradually more important multifactorial disease in both children and adults. Obese children and adolescents are at higher risk of becoming obese in adulthood, which is associated with an increased risk of mortality and morbidity. There is subclinical systemic inflammation in obesity. The study aimed to evaluate the hematological parameters as an indicator of inflammation in obese adolescents and to show the relationship of monocyte/HDL-cholesterol ratio, having a lipid component, with other inflammatory hematological parameters.
Materials and methods: We retrospectively reviewed the medical files of 60 patients, 30 obese and 30 healthy controls, aged between 11 and 16 years, who applied to the pediatric outpatient clinic. Laboratory tests, hematological parameters, gender, age, and BMI were compared between the groups. Correlations between monocyte/HDL-cholesterol ratio and other laboratory parameters in the obese group were examined.
Results: BMI, Alanine aminotransferase (ALT), C-reactive protein (CRP), triglyceride, insulin, and HOMA-IR levels of the obese adolescent group were statistically significantly higher than the control group (p<0.05). There was no statistically significant difference between the obese and control groups in terms of inflammatory hematological ratios (NLR, PLR, MLR, and monocyte/HDL-cholesterol ratio) (p>0.05). There was no statistically significant relationship between monocyte/HDL-cholesterol and other inflammatory hematological rates (p>0.05). There was a positive, moderate (48.6%), and statistically significant relationship between monocyte/HDL-cholesterol and MLR (p<0.05).
Conclusions: In our study, the NLR, PLR, MLR, and monocyte/HDL-cholesterol values of the obese adolescent group were similar to the control group. There was correlation between monocyte/HDL-cholesterol and monocyte/lymphocyte values. There was no correlation between other rates. Our data do not support the utility of inflammatory hematological rates as a biomarker in adolescent obesity. However, we believe that our study can shed light on other studies to be conducted.

Resumen

Introducción: La obesidad es una enfermedad multifactorial cada vez más importante tanto en niños como en adultos. Los niños y adolescentes obesos tienen un mayor riesgo de volverse obesos en la edad adulta, lo que se asocia con un mayor riesgo de mortalidad y morbilidad. Hay inflamación sistémica subclínica en la obesidad. El estudio tuvo como objetivo evaluar los parámetros hematológicos como indicador de inflamación en adolescentes obesos y mostrar la relación de la relación monocitos/colesterol HDL, que tiene un componente lipídico, con otros parámetros hematológicos inflamatorios.
Materiales y métodos: Se revisaron retrospectivamente los expedientes médicos de 60 pacientes, 30 obesos y 30 controles sanos, con edades comprendidas entre los 11 y los 16 años, que acudieron a la consulta externa de pediatría. Se compararon las pruebas de laboratorio, los parámetros hematológicos, el sexo, la edad y el IMC entre los grupos. Se examinaron las correlaciones entre la proporción de monocitos/colesterol HDL y otros parámetros de laboratorio en el grupo de obesos.
Resultados: Los niveles de IMC, alanina aminotransferasa (ALT), proteína C reactiva (PCR), triglicéridos, insulina y HOMA-IR del grupo de adolescentes obesos fueron estadísticamente significativamente más altos que los del grupo de control (p<0.05). No hubo diferencias estadísticamente significativas entre los grupos de obesidad y de control en términos de proporciones hematológicas inflamatorias (NLR, PLR, MLR y proporción de monocitos/colesterol HDL) (p>0,05). No hubo una relación estadísticamente significativa entre monocitos/colesterol HDL y otras tasas hematológicas inflamatorias (p>0,05). Hubo una relación positiva, moderada (48,6%) y estadísticamente significativa entre monocitos/colesterol HDL y MLR (p <0,05).
Conclusiones: En nuestro estudio, los valores de NLR, PLR, MLR y monocitos/colesterol HDL del grupo de adolescentes obesos fueron similares a los del grupo control. Hubo correlación entre los valores de monocitos/colesterol HDL y monocitos/linfocitos. No hubo correlación entre otras tasas. Nuestros datos no apoyan la utilidad de las tasas hematológicas inflamatorias como biomarcador en la obesidad adolescente. Sin embargo, creemos que nuestro estudio puede arrojar luz sobre otros estudios que se realizarán.
