Abstract:
Objective To investigate the correlation and predictive value of serum ferritin(SF),25(OH)D and early renal damage in children with new type 1 diabetes mellitus(T1DM).Methods A total of 102 newly diagnosed T1DM children admitted to the Department of Endocrinology,Genetics and Metabolism of our hospital from January 2020 to June 2023 were collected as the study objects.According to UACR,the study subjects were divided into T1DM group<30 mg/g(n=50),microalbuminuria group 30～300 mg/g(MUAlb)group(n=32),and macroalbuminuria group>300 mg/g(CUAlb)group(n=20).Another 65 healthy children who underwent physical examination during the same period were selected as normal control(NC)group.General data and biochemical indexes of all groups were compared to analyze the correlation and predictive value of changes in SF and 25(OH)D levels with early renal damage.Results The levels of SF and TG in NC,T1DM,MUAlb and CUAlb groups increased in turn(P<0.05),while 25(OH)D decreased in turn(P<0.05).The levels of TC,FC-P,FPG and HbA1c in the T1DM,MUAlb and CUAlb groups were higher than those in the NC group(P<0.05),and the levels of FIns was lower than that in the NC group(P<0.05).The level of LDL-C in MUAlb and CUAlb groups were higher than in NC group(P<0.05),the levels of TC,FPG and HbA1c in MUAlb and CUAlb groups were higher than those in T1DM group(P<0.05),and UACR was higher than that in NC and T1DM groups(P<0.05).LDL-C in MUAlb group was higher than that in T1DM group(P<0.05).Blood urea in the CUAlb group were higher than those in the NC group(P<0.05),Scr and UACR was higher than that in the MUA1b group(P<0.05),and eGFR was higher than that in the T1DM,MUAlb,and CUAlb groups(P<0.05).Spearman correlation analysis showed that SF were positively correlated with TC,LDL-C,TG,UACR and HbA1c(P<0.05)and negatively correlated with 25(OH)D(P<0.05).25(OH)D was negatively correlated with TC,LDL-C,TG,UACR,HbA1c(P<0.05).Logistic regression analysis showed that SF and 25(OH)D were the influencing factors of early renal injury in children with T1DM.ROC curve analysis showed that the area under the curve of SF and 25(OH)D was 0.813 and 0.808,with the sensitivity 67.3%and 78.8%,the specificity 80.0%and 72.0%,and the cut-off values were 113.6 ng/ml and 54.17 nmol/L,respectively.Conclusions The changes in serum SF and 25(OH)D levels are associated with different stages of early renal damage and may be involved in the occurrence and development of early renal damage in children with T1DM.
