Insights
Elevated serum transforming growth factor-beta1 (TGF-beta1) and epidermal growth factor (EGF) indicate a good therapeutic outcome in children with biliary atresia (BA). These growth factors were also positively correlated in BA patients.
Area of Science:
- Pediatric Hepatology
- Gastroenterology
- Biomarker Discovery
Background:
- Biliary atresia (BA) is a severe pediatric liver disease impacting hepatic repair.
- Transforming growth factor-beta1 (TGF-beta1) and epidermal growth factor (EGF) are implicated in liver healing processes.
Purpose of the Study:
- To investigate the association between serum TGF-beta1 and EGF levels and therapeutic outcomes in pediatric BA patients.
- To explore the correlation between TGF-beta1 and EGF in the context of BA treatment success.
Main Methods:
- Serum TGF-beta1 and EGF levels were quantified using ELISA in 67 postoperative BA patients and 10 healthy controls.
- BA patients were stratified into good (jaundice-free) and poor (persistent jaundice) outcome groups for comparative analysis.
- Clinical data and growth factor levels were compared; correlation analysis between TGF-beta1 and EGF was performed.
Main Results:
- Serum TGF-beta1 levels were significantly higher in BA patients compared to controls (p=0.0362).
- No significant difference in serum EGF was observed between BA patients and controls (p=0.744).
- Patients with good BA outcomes exhibited significantly higher serum TGF-beta1 (p=0.002) and EGF (p=0.02) levels compared to those with poor outcomes.
- A significant positive correlation was found between serum TGF-beta1 and serum EGF levels (r=0.3418, p=0.0046).
Conclusions:
- Elevated serum TGF-beta1 and EGF levels are associated with favorable therapeutic outcomes in pediatric BA.
- The positive correlation suggests a potential interplay between TGF-beta1 and EGF pathways in postoperative BA.
- These findings highlight TGF-beta1 and EGF as potential biomarkers for assessing BA treatment efficacy.
Background And Aim:
Biliary atresia (BA) is a serious liver disease in children. Since transforming growth factor-beta1 (TGF-beta1) and epidermal growth factor (EGF) are involved in the hepatic reparative process, our objective was to investigate whether serum TGF-beta1 and serum EGF levels were associated with therapeutic outcomes in BA.
Methods:
Serum levels of TGF-beta1 and EGF were determined with the ELISA method in 67 postoperative BA patients with a median age of 7 years and in 10 age-comparable healthy children. The BA patients were then divided into two groups depending on their therapeutic outcome: good outcome (jaundice-free) and poor outcome (persistent jaundice). Clinical data, serum TGF-beta1 and serum EGF levels were compared between the two groups of BA patients. Correlation analysis of serum TGF-beta1 with serum EGF was carried out. Data are expressed as mean +/- SD.
Results:
Serum TGF-beta1 levels of BA patients were higher than those of controls (86.6 +/- 15.7 vs. 75.7 +/- 8.8 ng/ml, p = 0.0362). However, there was no difference in serum EGF between BA patients and controls (133.1 +/- 66.6 vs. 125.4 +/- 88.9 pg/ml, p = 0.744). Further subgroup analysis showed that patients with good outcomes (n = 40) had higher serum TGF-beta1 and serum EGF levels than patients with poor outcomes (TGF-beta1: 91.2 +/- 16.5 vs. 79.6 +/- 11.7 ng/ml, p = 0.002; EGF: 148.5 +/- 65.0 vs. 110.3 +/- 63.4 pg/ml, p = 0.02). In addition, serum TGF-beta1 was positively correlated with serum EGF (Pearson's r = 0.3418, p = 0.0046).
Conclusion:
Elevated serum TGF-beta1 and serum EGF levels were associated with a good outcome in BA patients. There was a positive correlation between serum TGF-beta1 and serum EGF. This suggests that the resultant TGF-beta1 and EGF pathways may be involved in the pathophysiological process in postoperative BA.
