Using RIBA NS5 antibody was measured in 31 HCV RNA positive serotype 1 patients, and the serum levels of ALT were monitored for an average of three years. As a result, 22 asymptomatic HCV carriers (group A) were found to be NS5 antibody negative (-) and nine to be NS5 antibody positive (4+). By contrast, in 25 patients with chronic inactive hepatitis C (group B), three patients were NS5 antibody negative (-), and 22 patients were NS5 antibody positive (4+), indicating a significant difference between the two groups (p<0.01 chi square test).Furthermore, in group A, 22 NS5 antibody (-) patients (group I) maintained normal serum levels of ALT significantly longer than the 9 NS5 antibody (4+) patients (group II) (p<0.01, Kaplan-Meier Method). Therefore, the measurement of NS5 antibody of RIBA was clinically useful in identifing asymptomatic (HCVRNA positive, serotype 1) HCV carriers.

We examined the usefulness of serum leptin concentration as an index for the diagnosis of fatty liver. Twenty-two patients diagnosed with fatty liver by abdominal ultrasonography, participated in this study together with 7 indinduels as controls. As laboratory findings showed, body fat percentage (29.5±1.4 vs 19.1±1.6%, P<0.001), BMI (25.7±0.7 vs 20.8±1.0 kg/m2, P<0.005), procollagen III peptide (P III P) (0.58±0.04 vs 0.42±0.04 U/ml, P<0.05), and serum leptin levels (7.3±1.0 vs 2.9±0.5 ng/ml, P<0.001) were significantly higher in the fatty liver group than in the control group. Serum leptin levels were correlated significantly with body fat percentage (r=0.76, P<0.0001) and BMI (r=0.61, P<0.001), though there was a significant correlation between serum leptin levels and liver-kidney contrast (r=0.47, P<0.05) only in males. In addition, when the fatty liver group was classified into two groups by GPT levels, m-GOT (mitochondrial glutamate-oxaloacetate transaminase) (8.6±1.0 vs 5.7±1.0 IU/l/37°C, P<0.05) and P III P (0.65±0.06 vs 0.49±0.04 U/ml, P<0.05) were significantly higher in the elevated GPT group than in the normal GPT group.These results suggest that serum leptin levels may be indicative of fatty liver and that fatty liver is not always a reversible disease.

A 65-year-old man was referred to our hospital in April 2003 with a pancreas tumor detected by a thorough medical checkup. Computed tomography (CT) showed swelling of the pancreatic body and tail, and magnetic resonance cholangiopancreatography (MRCP) showed only the main pancreatic duct in the head of the pancreas. Diagnosing autoimmune pancreatitis, we observed the patient without medication. However, one year later CT showed stenosis of the splenic artery and portal vein accompanied by development of collateral circulation around the pancreas. He had no symptoms, and CT showed no changes in the pancreatic swelling.;;He was admitted to our hospital on January 6, 2005, presenting with a history of jaundice which first appeared on January 1, 2005, and increased collateral circulation around the pancreas with pancreatic swelling were seen on CT. We started prednisolone therapy at 40 mg/day for exacerbation of autoimmune pancreatitis. Serum bilirubin levels improved from 11.9 mg/dl to 2.5 mg/dl, and pancreatic swelling also improved four weeks after starting therapy.;;We present a rare case of autoimmune pancreatitis that developed marked collateral circulations.
