Aim: A patient with severe type Ⅲ hyperlipoproteinemia and familial hypercholesterolemia (FH) was previously reported (Metabolism, 44,1995:460-465). In the current study, the patient's apolipoprotein (apo) E gene was analyzed. Methods: An apo E isoform analysis was performed using isoelectric focusing and immunoblotting. In addition, after DNA preparation, a restriction fragment length polymorphism analysis and DNA sequence analysis were performed. Results: The patient's apo E phenotype was E2/E1, and the genotype was ε2/ε2. The sequence analysis of the patient's DNA revealed a new variant of apo E, which involves a single substitution of one serine (AGC) for one arginine (CGC) at position 142, thereby adding one negatively charged unit to apo E2. Therefore, the patient was compound heterozygous for apo E1 (Arg142Ser) and apo E2 (Arg158Cys). Conclusions: A novel mutation, apo E1 Nagoya (Arg142Ser) in a patient with severe type Ⅲ hyperlipoproteinemia with heterozygous FH was characterized. Since the presence of arginine at the amino acid residue 142 of apo E is considered to play an important role in binding to LDL receptors, the mutation apo E1 Nagoya (Arg142Ser) likely contributed to the expression of severe type Ⅲ hyperlipoproteinemia in this patient.

Background and Aims Radiofrequency ablation (RFA) has replaced percutaneous ethanol injection (PEI) as the treatment of choice for hepatocellular carcinoma (HCC); however, control of local tumor progression (LTP) remains a challenge in perivascular HCC. The aim of this study is to determine whether PEI added to RFA can reduce the LTP rate in perivascular HCC patients. Methods We retrospectively analyzed 167 patients, with 197 newly diagnosed HCC nodules with peritumoral vessels, who underwent either RFA plus PEI or RFA monotherapy as the first-line treatment between June 2001 and April 2015. Ethanol was injected inside the tumor close to the peritumoral vessels in the combination therapy group. Patients were matched 1:1 according to their propensity scores to reduce selection bias; cumulative LTP was then analyzed using log-rank tests and Cox proportional hazard regression analyses. Results The two matched groups comprised 62 tumors each. The overall median follow-up period was 34 months (range, 1–140 months). In the RFA plus PEI group, the cumulative LTP rates were 5.7%, 15.5%, and 20.4% at 1, 3, and 5 years, respectively; in the RFA monotherapy group, the rates were 13.2%, 32.0%, and 40.2%, respectively. The rates were significantly lower in the RFA plus PEI group (P = 0.032). Cox proportional hazard regression analysis showed that PEI combination treatment was significantly associated with a reduced risk of local HCC recurrence (hazard ratio, 0.44; 95% confidence interval, 0.19–0.93; P = 0.031). Discussion/Conclusion The risk of LTP after RFA for perivascular HCC can be significantly reduced by injecting ethanol close to the peritumoral vessels.

We report a case of anorexia nervosa (AN) with gastroesophageal varices (GEV) in a 36-year-old woman. The patient presented to our hospital with progressive bloating due to severe ascites. She had no history of alcohol intake. Esophagogastroduodenoscopy and enhanced computed tomography revealed GEV and multiple hepatic nodules, respectively. The histological examination of a liver biopsy specimen revealed similar features to nonalcoholic fatty liver disease and showed hyperplastic nodules that were suspected to be related to the uneven distribution of portal blood flow in the liver. In conclusion, patients with long-term AN should undergo abdominal imaging to detect signs of portal hypertension.
