Partial splenic embolization prior to combination therapy of interferon and ribavirin in chronic hepatitis C patients with thrombocytopenia

Aim:  A low platelet count leads to dose reduction of interferon (IFN) and is associated with failure to achieve a sustained virological response (SVR) in chronic hepatitis C patients. However, partial splenic embolization (PSE) is effective for treating thrombocytopenia resulting from hypersplenism.

Large waist circumference is a risk factor for reflux esophagitis in Japanese males.

Background/Aims: The prevalence of reflux esophagitis, which might lead to development of Barrett’s esophagus and esophageal adenocarcinoma, has been increasing. The aim of this study was to assess risk factors for reflux esophagitis. Methods: We conducted a cross-sectional study of 1,495 Japanese subjects undergoing health checkups (822 males and 673 females; median age 50 years) at a tertiary care center. Results: One hundred and twenty-seven subjects (8%) had reflux esophagitis and hiatal hernia was observed in 292 subjects (20%). Reflux esophagitis (13 vs. 3%) and hiatal hernia (28 vs. 9%) were more frequent in males than females. Significant differences in clinical backgrounds were observed between females and males. Multivariate logistic regression analyses revealed that hiatal hernia (OR 6.63, 95% CI 2.47–17.8; p = 0.0002) was associated with reflux esophagitis in females. In males, age (per 1-year increment: OR 0.96, 95% CI 0.94–0.99; p = 0.007), hiatal hernia (OR 3.16, 95% CI 2.05–4.87; p < 0.0001) and waist circumference (per 1-cm increase: OR 1.09, 95% CI 1.02–1.15; p = 0.006) were associated with reflux esophagitis. Conclusions: Abdominal obesity may be an important risk factor for reflux esophagitis in males compared with females.
