Fasting hyperglycaemia following trans-catheter arterial chemo-embolization for hepatocellular carcinoma in cirrhosis

Following a hyperosmolar diabetic coma in a cirrhotic patient with hepatocellular carcinoma undergoing transcatheter arterial chemo-embolization, we assessed the prevalence, severity, causes and prognostic impact of impaired glucose metabolism following transcatheter arterial chemo-embolization.

Plasma glucose, pancreatic and thyroid hormones, cortisol, growth hormone, ACTH and TSH concentrations were determined before and after transcatheter arterial chemo-embolization in 98 patients (70 with a normal fasting glucose, 7 with mild fasting hyperglycaemia and 21 diabetics) undergoing 226 transcatheter arterial chemo-embolization procedures. Child status, body temperature, serum ALT and amylase levels, tumour size, gelfoam embolization and disease aetiology were recorded. Liver function was assessed before and after transcatheter arterial chemo-embolization by measuring monoethylglycinexylidide formation after i.v. lidocaine.

A significant rise in glucose levels (p < 0.0001) was observed in 30/98 patients. Hyperglycaemia was more frequent in diabetics (67%) and patients with mild fasting hyperglycaemia (71%). Glucose concentrations doubled in 12 patients; 4 required long-term insulin. Fever, a previously altered carbohydrate metabolism and raised ALT levels were prognostic factors for hyperglycaemia (p < 0.01). Plasma C-peptide, glucose/insulin and glucose/C-peptide ratios, were increased after transcatheter arterial chemo-embolization (p < 0.05). Transcatheter arterial chemo-embolization was followed by a reduction in the monoethylglycinexylidide formation capacity (p < 0.05), particularly in hyperglycaemia patients (p < 0.02).

Transcatheter arterial chemo-embolization is frequently followed by a derangement in glucose metabolism which is potentially severe, associated with preceding glucose imbalance, fever and a transient deterioration in liver function.
