Few studies have directly compared the long-term clinical outcomes of entecavir (ETV) and tenofovir disoproxil fumarate (TDF). This study aimed to compare the risk of mortality, liver transplantation and hepatic complications including hepatocellular carcinoma (HCC) and hepatic decompensation between these drugs in treatment-naïve chronic hepatitis B (CHB). We performed a longitudinal observational analysis of data from 1325 consecutive adult CHB patients with a cumulative adherence of ≥80% to treatment with ETV (n = 721) or TDF (n = 604) at a tertiary referral hospital in Ulsan, Korea, from 1 January 2007 through 31 April 2017. Among the patients, 708 were analysed using propensity score matching with a ratio of 1:1. In the follow-up period of up to 5 years, five patients (0.4%) died, three patients (0.2%) underwent liver transplantation (LT) and 54 patients (4.1%) developed HCC. Hepatic decompensation occurred in 24 (1.8%) patients. ETV therapy did not significantly differ from TDF therapy regarding the risk of liver-related death or LT (HR 0.96; 95% CI, 0.23-4.07; log-rank P = 0.955), HCC (HR, 1.36; 95% CI, 0.72-2.56; log-rank P = 0.340) and hepatic decompensation (HR, 1.64; 95% CI, 0.67-4.00; log-rank P = 0.276). In the 708 propensity-matched pairs, ETV and TDF were also not significantly different with respect to the risk of mortality, LT and hepatic complications. In this longitudinal observational study of 1325 patients with CHB, ETV and TDF therapies were not significantly different regarding the risk of mortality, HCC, LT and hepatic decompensation.
Endoscopic enucleation of gastric SETs originating in the muscularis propria layer was a safe and effective method for the histologic diagnosis and removal of small gastric SETs, especially those located in the cardia and the high body of the stomach.
SUMMARY BackgroundTapentadol is a mu-opioid receptor agonist and norepinephrine reuptake inhibitor. In clinical trials, tapentadol provided somatic pain relief comparable to muopioids such as oxycodone, with significantly less gastrointestinal adverse effects. The acute effects of tapentadol on gastrointestinal and colonic transit are unclear.
Background/Aims: Low-level viremia (LLV) after nucleos(t)ide analog treatment was presented as a possible cause of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B (CHB). However, detailed information on patients’ adherence in the real world was lacking. This study aimed to evaluate the effects of LLV on HCC development, mortality, and cirrhotic complications among patients according to their adherence to entecavir (ETV) treatment.Methods: We performed a retrospective observational analysis of data from 894 consecutive adult patients with treatment-naïve CHB undergoing ETV treatment. LLV was defined according to either persistent or intermittent episodes of <2,000 IU/mL detectable hepatitis B virus DNA during the follow-up period. Good adherence to medication was defined as a cumulative adherence ≥90% per study period.Results: Without considering adherence in the entire cohort (n=894), multivariate analysis of the HCC incidence showed that LLV was an independent prognostic factor in addition to other traditional risk factors in the entire cohort (<i>P</i>=0.031). Good adherence group comprised 617 patients (69.0%). No significant difference was found between maintained virologic response and LLV groups in terms of the incidence of liver-related death or transplantation, HCC, and hepatic decompensation in good adherence group, according to multivariate analyses.Conclusions: In patients with treatment-naïve CHB and good adherence to ETV treatment in the real world, LLV during treatment is not a predictive factor for HCC and cirrhotic complications. It may be unnecessary to adjust their antiviral agent for patients with good adherence who experience LLV during ETV treatment.
Gastrointestinal stromal tumor (GIST) represents the most common kind of mesenchymal tumor that arises from the alimentary tract. GIST is currently defined as a gastrointestinal tract mesenchymal tumor showing CD117 (c-kit protein) positivity at immunohistochemistry. Throughout the whole length of the gastrointestinal tract, GIST arises most commonly from the stomach followed by the small intestine, the colorectum, and the esophagus. Only 3%-5% of GISTs occur in the duodenum, and especially, if GIST arises from the C loop of the duodenum, it can be difficult to differentiate from the pancreas head mass because of its anatomical proximity. Here, we report a case of duodenal GIST, which was assessed as a pancreatic head tumor preoperatively.
Quantitative hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) assays are emerging as effective tools of on-treatment predictors of response to antiviral agents, in addition to monitoring serum HBV DNA levels. However, the dynamic relationship between quantitative HBsAg, as well as HBeAg and HBV DNA, and the predictability of subsequent clinical outcomes during entecavir (ETV) therapy remain unclear. Eighty-two patients with HBeAg-positive chronic hepatitis B (CHB) received ETV therapy for ≥3 years. Virologic response (VR) after 3 years of ETV therapy was achieved in 73 (89.0%) patients. Among baseline and on-treatment factors, on-treatment HBV DNA levels performed better with respect to the prediction of response than HBsAg and HBeAg levels. Especially, the performance of absolute values of HBV DNA with respect to response was superior to HBV DNA decline from the baseline. The best predictive value was an absolute HBV DNA level of 2.3 log(10) IU/mL at month 6 (areas under the curve [AUROC], 0.977; 95% CI, 0.940-1.000; P < 0.001). HBeAg seroconversion after 3 years of therapy was achieved in 26 (31.7%) patients. On-treatment HBeAg levels performed better with respect to the prediction of seroconversion than HBsAg and HBV DNA levels. The best cut-off value for the HBeAg level at month 12 for the prediction of seroconversion was 0.62 log(10) PEIU/mL. Although the HBsAg level at baseline is often used to predict the antiviral potency of entecavir, on-treatment HBV DNA and HBeAg levels are more helpful for prediction of subsequent clinical outcomes in HBeAg-positive CHB patients with entecavir treatment.
Background/Aims
Patient education has been shown to be beneficial in several diseases. To properly educate patients with gastroesophageal reflux disease (GERD), it is necessary to understand how much they already know about their disease. However, no study has examined the degree of disease knowledge in Korean patients with GERD. Therefore, we conducted this study to assess the degree of knowledge in such patients.
Methods
This multicenter prospective study was conducted from January 2014 to January 2015. A total of 746 patients (mean age, 52 years; 57.6% female) were enrolled from 7 hospitals in Korea. Inclusion criteria were diagnosis of GERD and ability to properly complete a survey. Degree of disease knowledge was assessed using the translated, validated Korean Urnes questionnaire, which consists of 22 items related to GERD.
Results
Mean percentage of correct answers was 46.3% and mean GERD knowledge score was 9.6. Degree of knowledge (mean percentage of correct answers) regarding etiology, prognosis, and treatment of GERD were 49.5%, 36.7%, and 37.5%, respectively. Degree of disease knowledge differed significantly according to age (
P
< 0.001), education (
P
< 0.001), income (
P
= 0.028), and occupation (
P
< 0.001). In multivariate analysis, using multiple logistic regression, the higher knowledge score group tended to have higher education and professional occupation.
Conclusions
The surveyed Korean patients had relatively low disease knowledge, suggesting that a GERD educational program may be beneficial in Korea. Formulation of a program is underway.
