Syncope is a common chief complaint in emergency departments, and although causes in most patients with syncope are benign, some patients have a serious disease. Here we report a 50-year-old patient with facial trauma who had past history of alcoholic liver cirrhosis. He fell down by syncope due to portopulmonary hypertension (PPHTN) accompanied by portal hypertension. Oral ambrisentan, a potent ETA-selective receptor, 2.5 mg once a day was initiated. His ECG and the results of cardiac catheterization showed improvement in hemodynamic abnormality after the treatment. Also, the patient had no significant symptoms, including syncope, for nine months after receiving ambrisentan.

The current requirement for biomarkers to detect hepatitis B virus (HBV) infection is polarized. One is a fully-automated and highly sensitive measurement system; the other is a simple system for point-of-care testing (POCT) in resource-limited areas. Hepatitis B core-related antigen (HBcrAg) reflects intrahepatic covalently closed circular DNA and serum HBV DNA. Even in patients with undetectable serum HBV DNA or HBsAg loss, HBcrAg may remain detectable. Decreased HBcrAg levels are associated with reduction of the occurrence of hepatocellular carcinoma (HCC) in chronic hepatitis B. Recently, a fully-automated, novel high-sensitivity HBcrAg assay (iTACT-HBcrAg, cut-off value: 2.1 logIU/mL) has been developed. This attractive assay has been released in Japan very recently. iTACT-HBcrAg can be useful for monitoring HBV reactivation and prediction of HCC occurrence, as an alternative to HBV DNA. Moreover, monitoring HBcrAg may be suitable for determining the therapeutic effectiveness of approved drugs and novel drugs under development. Presently, international guidelines recommend anti-HBV prophylaxis for pregnant women with high viral loads to prevent mother-to-child transmission of HBV. However, >95% of HBV-infected individuals live in countries where HBV DNA quantification is not available. Worldwide elimination of HBV needs the scaling-up of examination and medication services in resource-limited areas. Based on this situation, a rapid and easy HBcrAg assay as a POCT is valuable. This review provides the latest information regarding the clinical use of a new surrogate marker, HBcrAg, in HBV management, based on iTACT-HBcrAg or POCT, and introduces novel agents targeting HBV RNA/protein.

BACKGROUND/AIMS: Noninvasive objective monitoring is advantageous for optimizing treatment strategies in patients inflammatory bowel disease (IBD). Fecal calprotectin (FCP) is superior to traditional biomarkers in terms of assessing the activity in patients with IBD. However, there are the differences among several FCP assays in the dynamics of FCP. In this prospective multicenter trial, we investigated the usefulness of FCP measurements in adult Japanese patients with IBD by reliable enzyme immunoassay using a monoclonal antibody. METHODS: We assessed the relationship between FCP levels and disease or endoscopic activity in patients with ulcerative colitis (UC, n=64) or Crohn’s disease (CD, n=46) compared with healthy controls (HCs, n=64). RESULTS: FCP levels in UC patients strongly correlated with the Disease Activity Index (rs =0.676, P < 0.0001) and Mayo endoscopic subscore (MES; rs =0.677, P < 0.0001). FCP levels were significantly higher even in patients with inactive UC or CD compared with HCs (P=0.0068, P < 0.0001). The optimal cutoff value between MES 1 and 2 exhibited higher sensitivity (94.1%). FCP levels were significantly higher in active UC patients than in inactive patients (P < 0.001), except those with proctitis. The Crohn’s Disease Activity Index tended to correlate with the FCP level (rs =0.283, P=0.0565). CONCLUSIONS: Our testing method using a monoclonal antibody for FCP was well-validated and differentiated IBD patients from HCs. FCP may be a useful biomarker for objective assessment of disease activity in adult Japanese IBD patients, especially those with UC.

Objectives High gestational weight gain (GWG) is associated with perinatal risks to mother and child. Research shows that non-Japanese Asian women have higher GWG than Japanese women. However, no studies have compared GWG in these two populations using GWG recommendations in accordance with Japanese and Institute of Medicine (IOM) guidelines. The study aim was to compare GWG in non-Japanese Asian and Japanese pregnant women.Methods This was a retrospective observational study. All participants were aged ≥20 years and gave birth between September 2019 and the end of October 2020 at one perinatal medical center in Japan. Medical record data were analyzed for 170 non-Japanese Asian and 316 Japanese pregnant women. We used t-tests and chi-square tests to examine differences in age, parity, smoking status, antenatal checkups, pre-pregnancy body mass index, and GWG. Logistic regression analysis was used to estimate odds ratios (95% confidence intervals) for above- and below-recommended GWG by non-Japanese Asian and Japanese status. We also analyzed differences in delivery type, abnormal blood loss, and birth size according to GWG.Results After adjustment for confounding factors, the multivariable-adjusted OR and 95% CI for GWG above the Japanese guidelines recommendations was 1.86 (1.23-2.81) and that for GWG above IOM guidelines recommendations was 2.46 (1.45-4.16) for non-Japanese Asian women, as compared with Japanese women. Conversely, the multivariable-adjusted OR and 95% CI for GWG below Japanese guidelines recommendations was 1.55 (1.03-2.32) and that for GWG below IOM guidelines recommendations was 1.87 (1.26-2.76) for Japanese women, compared with non-Japanese Asian women. Conclusion Because Japanese women tend to be below recommended GWG and non-Japanese Asian women tend to be above recommended GWG, midwives need to provide careful guidance to reduce perinatal risks.
