Increased Interleukin-6 as Infl ammatory Response and Magnesium Defi ciency in Pre-dialysis Chronic Kidney Disease of Indonesian Children

Chronic kidney disease (CKD) is a serious health problem in children, with increasing morbidity and mortality rates throughout the world. Children with CKD tend to experience magnesium (Mg) defi ciency that can stimulate an infl ammatory response in the body. One of the infl ammatory responses is an increase of Interleukin-6 (IL-6).  Study to analyze the correlation between Mg and IL-6 in pre-dialysis CKD children. The methods a cross sectional study was conducted in Dr Soetomo General Academic Hospital from November 2018 to April 2019. Children with pre-dialyis CKD were included in this study. Variables of serum Mg level (mg/dL) and infl ammatory marker (IL-6) were measured from the blood and analyzed by ELISA method. The correlation between Mg and IL-6 was analyzed with Spearman’s correlation test with p <0.05.  Result a total of 47 children (27 boys vs 20 girls) between 3 months to 18 years old, with pre-dialysis CKD and no history of magnesium supplementation were included. The primary disease that causes of CKD were lupus nephritis (38.3%), nephrotic syndrome (23.4%), urologic disorder (23.4%),  tubulopathy (10.6%) and others (4.3%). The average IL-6 level was 55.42±43.04 pg/dL and Mg level was 2.06±1.54 mg/dL. There were no signifi cant correlation between IL-6 level and Mg level with staging of CKD and duration of illness (p>0.05), but there was a signifi cant correlation between serum Mg level and IL-6 level (r=-0.748; p<0.001). Magnesium levels have a signifi cant inverse correlation with IL-6 levels in pre-dialysis CKD children. The lower the Mg levels in the blood, the higher IL-6 levels and vice versa.
