Association between phospholipids and free cholesterol in high-density lipoprotein and the response to hepatitis C treatment in Japanese with genotype 1b.

Pegylated interferon and ribavirin combination therapy is the standard treatment for patients with chronic hepatitis C (CHC), but treatment failure can be difficult to predict. We and others have reported a relation between lipid values and sustained viral responses in patients with CHC. However, the relationship between lipid values and treatment failure has not been previously reported. The present study investigated the association between the profiles of phospholipids and free cholesterol (FC), the main constitutive ingredients of the surface of lipoprotein, classified according to particle size and hepatitis C treatment, and determined the usefulness of these parameters for predicting the outcome of treatment. Fifty-five patients with CHC (33 men and 22 women) were included in the study. The serum total cholesterol, triglyceride, phospholipids, and FC levels in the lipoprotein subclasses were determined using high-performance liquid chromatography with gel permeation columns, enabling the lipoproteins to be classified into 13 subclasses according to particle size. According to a univariate analysis, the treatment failure group had a significantly higher serum phospholipid level overall in the high-density lipoprotein (HDL) and medium HDL fractions as well as a higher serum FC level in the HDL fraction and all HDL subclass fractions compared with the corresponding values in the non-nonvirological response group. Higher serum phospholipid and FC concentrations in the HDL subclasses were predictive of a failure to respond in patients with genotype 1b.

Association between lipoprotein subfraction profile and the response to hepatitis C treatment in Japanese patients with genotype 1b.

Pegylated interferon and ribavirin combination therapy is the standard treatment for patients with chronic hepatitis C (CHC). Some groups have reported a relation between lipid values and response while others have reported that microsomal triglyceride transfer protein, a key enzyme in the assembly and secretion of lipoproteins, was related to hepatitis C virus (HCV). The aim of this study was to investigate the association between the lipoprotein profiles, classified according to size, and hepatitis C treatment and the usefulness for predicting the outcome of treatment. Forty-four patients with CHC (27 men and 17 women) were included in the study. The serum cholesterol and triglyceride (TG) levels in the lipoprotein subclasses were determined using high-performance liquid chromatography with gel permeation columns, which classified lipoproteins into 20 subfractions based on particle size. According to a univariate analysis, those who achieved an sustained viral response (SVR) had a significantly higher serum total cholesterol level, higher cholesterol levels in the low-density lipoprotein subfraction (25.5 nm in diameter) and the very low-density lipoprotein (VLDL) subfraction (44.5 and 36.8 nm), and a higher serum TG level in the VLDL subfraction (44.5 nm), compared with the corresponding values in the non-SVR group. Higher serum cholesterol and TG concentrations in the lipoprotein subfractions were predictive of an SVR to therapy for HCV infection with genotype 1b prior to the start of interferon treatment.

Gastric variceal rupture successfully treated with repeated EIS and EVL.

A 68-year-old female with liver cirrhosis presented at the Emergency Room of our hospital with copious tarry stools. Upper gastrointestinal endoscopy showed an isolated gastric variceal rupture, and we performed endoscopic injection sclerotherapy using cyanoacrylate, on four occasions, resulting in successful hemostasis. Injection of CA is a useful emergency treatment option for gastric variceal bleeding without gastro-renal shunt.
