[Preliminary results on blood carnitine levels in children with hepatic pathology]
Insights
Children with acute hepatitis show low serum carnitine levels, which correlate with illness severity and improve with recovery. Chronic hepatitis patients had normal carnitine levels, suggesting a link to the absence of steatosis.
Area of Science:
- Biochemistry
- Pediatric Hepatology
- Nutritional Science
Background:
- Carnitine deficiency is linked to weakness and steatosis in certain pathologies.
- Carnitine plays a crucial role in fatty acid metabolism and energy production.
Purpose of the Study:
- To investigate serum carnitine levels in children with various forms of liver disease.
- To explore the correlation between carnitine levels, clinical status, and biochemical markers in pediatric hepatitis.
Main Methods:
- Serum carnitine levels were measured in 14 children diagnosed with hepatic diseases, including acute HAV hepatitis, acute HBV hepatitis, toxic hepatitis, and chronic hepatitis.
- Serial blood tests were conducted in 5 patients to monitor carnitine levels throughout their illness and recovery.
- Liver biopsy findings were considered, particularly the presence or absence of steatosis.
Main Results:
- Children with acute, infective, and toxic hepatitis exhibited significantly lower serum carnitine levels (25.71 +/- 2.14 nM/ml) compared to normal controls (50.87 +/- 1.46 nM/ml).
- In cases of acute hepatitis, serial testing revealed a positive correlation between clinical improvement, decreasing aminotransferase levels, and increasing serum carnitine.
- Patients with chronic hepatitis presented with normal serum carnitine levels, which may be associated with the absence of hepatic steatosis.
Conclusions:
- Serum carnitine deficiency is a characteristic finding in children suffering from acute forms of hepatitis.
- Carnitine levels serve as a potential biomarker for disease activity and recovery in pediatric hepatitis.
- The absence of steatosis in chronic hepatitis might be linked to preserved carnitine homeostasis.
Abstract:
A deficiency of exogenous and endogenous carnitine is present in those pathologies in which the most important clinical sign is represented by weakness and steatosis. We have studied the serum levels of carnitine in 14 children with hepatic disease (8 with acute HAV hepatitis, 2 with acute HBV hepatitis, 2 with toxic hepatitis, 2 with chronic hepatitis). In patients with acute, infective and toxic hepatitis we have found levels of carnitine (25.71 +/- 2.14 nM/ml) below normal (50.87 +/- 1.46 nM/ml). In 5 cases we have performed two blood tests, at admittance to the hospital and at the end of the illness. The variability in carnitine levels in these two blood exams shows a clear correlation with clinical improvement, decrease in aminotransferase and increase in serum carnitine. In chronic hepatitis we have found normal levels of carnitine. Probably it is correlated with the absence of steatosis seen at hepatic biopsy.
