ABSTRACT
Abstract

Introduction:

In this study, we aimed to detect the cytokine that is involved in the early stage of chronic kidney disease and associated with cardiovascular disease.

Methods:

We included 50 patients who were diagnosed with predialytic chronic kidney disease and 30 healthy pediatric patients in Ege University Medical Faculty Pediatric Clinic, İzmir/Turkey. Interleukin-8 (IL-8), interleukin-10 (IL-10), interleukin-13 (IL-13), and transforming grow factor-β1 (TGF-β1) levels (pg/mL) were measured by ELISA. Carotid-femoral pulse wave velocity (PWV), augmentation index (Aix), carotid intima media thickness (cIMT), and left ventricular mass index (LVMI) were evaluated as markers of cardiovascular disease. The presence of a cardiovascular disease marker was defined as an abnormality in any of the parameters (cIMT, PWV, Aix, and left ventricular mass index (SVKI)). The patient group was divided into two groups as with and without cardiovascular disease.

Results:

Mean Aix and PWV values were higher in CKD patients than controls (Aix CKD 32.8±11.11%, healthy

subjects:

6.74±6.58%, PWV CKD 7.31±4.34m/s, healthy

subjects:

3.42±3.01m/s, respectively; p=0.02, p=0.03). The serum IL-8 levels of CKD were significantly higher than of healthy subjects 568.48±487.35pg/mL, 33.67±47.47pg/mL, respectively (p<0.001). There was no statistically significant difference between IL-8, IL-10, IL-13, TGF-1, in CKD patients with and without cardiovascular disease (p> 0.05).

Discussion:

IL-8 is the sole cytokine that increases in pediatric patients with chronic kidney disease among other cytokines (IL-10, IL-13 and TGF-β1). However, we did not show that IL-8 is related to the presence of cardiovascular disease.
RESUMO
Resumo

Introdução:

Neste estudo, o objetivo foi detectar a citocina envolvida no estágio inicial da doença renal crônica e associada à doença cardiovascular.

Métodos:

Incluímos 50 pacientes diagnosticados com doença renal crônica pré-dialítica e 30 pacientes pediátricos saudáveis na Clínica Pediátrica da Faculdade de Medicina, Universidade de Ege, İzmir/Turquia. Níveis de interleucina-8 (IL-8), interleucina-10 (IL-10), interleucina-13 (IL-13), fator de transformação do crescimento -β1 (TGF-β1) (pg/mL) foram medidos por ELISA. Velocidade de onda de pulso carotídeo-femoral (VOP), índice de amplificação (AIx), espessura da camada íntima-média da carótida (cIMT), índice de massa do ventrículo esquerdo (IMVE) foram avaliados como marcadores de doença cardiovascular. A presença de marcador de doença cardiovascular foi definida como uma anormalidade em qualquer dos parâmetros (cIMT, VOP, AIx, índice de massa do ventrículo esquerdo (IMVE)). Os pacientes foram divididos em dois grupos como com e sem doença cardiovascular.

Resultados:

Valores médios de AIx e VOP foram maiores em pacientes com DRC que nos controles (AIx DRC 32,8±11,11%, indivíduos saudáveis 6,74±6,58%, VOP DRC 7,31±4,34m/s, indivíduos saudáveis 3,42±3,01m/s, respectivamente; p=0,02, p=0,03). Níveis séricos de IL-8 de DRC foram significativamente maiores que de indivíduos saudáveis 568,48±487,35pg/mL, 33,67±47,47pg/mL, respectivamente (p<0,001). Não houve diferença estatisticamente significativa entre IL-8, IL-10, IL-13, TGF-1, em pacientes com DRC com e sem doença cardiovascular (p> 0,05). Discussão IL-8 é a única citocina que aumenta em pacientes pediátricos com doença renal crônica entre outras citocinas (IL-10, IL-13 e TGF-β1). Entretanto, IL-8 não se associou à presença de doença cardiovascular.
