Eradication Rate Using a First-line Triple Therapy for Helicobacter pylori Infection in Yeongdong, Gangwon Province, Korea

Background/Aims@#The eradication success rate of Helicobacter pylori (H. pylori) infection with a first-line standard triple therapy (STT) has been decreasing in Korea. However, treatment outcomes of H. pylori infection in Yeongdong, Gangwon Province have been scarcely reported. This study aimed to investigate the treatment outcomes of H. pylori infection in a single tertiary care hospital with regional characteristics. @*Materials and Methods@#From July 2018 to June 2019, a total of 592 patients who underwent STT consisting of a proton pump inhibitor, amoxicillin, and clarithromycin for 7 to 14 days as a first-line H. pylori eradication therapy were included. Demographic data and treatment outcomes were retrospectively reviewed using medical records. @*Results@#The median age of 592 patients was 58 years (range 23 to 86) and 329 patients (55.6%) were men. The indication for eradication therapy included chronic atrophic gastritis (57.9%), peptic ulcer disease (19.6%), and gastric neoplasm after endoscopic resection (5.9%). Most patients (92.2%) received a 7-day course of STT. Eradication rate of STT was 64.0% (379/592). Rescue therapy was performed in 146 patients, and the final eradication rate reached 85.6% (507/592). @*Conclusions@#Eradication rate of STT in Yeongdong area of Gangwon Province was unsatisfactory, warranting the consideration of a first-line eradication regimen other than STT.

Reappraisal of sepsis-3 and CLIF-SOFA as predictors of mortality in patients with cirrhosis and infection presenting to the emergency department: A multicenter study

Background/Aims@#Sepsis-3 criteria and quick Sequential Organ Failure Assessment (qSOFA) have been advocated to be used in defining sepsis in the general population. We aimed to compare the Sepsis-3 criteria and Chronic Liver Failure-SOFA (CLIF-SOFA) scores as predictors of in-hospital mortality in cirrhotic patients admitted to the emergency department (ED) for infections. @*Methods@#A total of 1,622 cirrhosis patients admitted at the ED for infections were assessed retrospectively. We analyzed their demographic, laboratory, and microbiological data upon diagnosis of the infection. The primary endpoint was inhospital mortality rate. The predictive performances of baseline CLIF-SOFA, Sepsis-3, and qSOFA scores for in-hospital mortality were evaluated. @*Results@#The CLIF-SOFA score proved to be significantly better in predicting in-hospital mortality (area under the receiver operating characteristic curve [AUROC], 0.80; 95% confidence interval [CI], 0.78–0.82) than the Sepsis-3 (AUROC, 0.75; 95% CI, 0.72–0.77, P10%; this is the cutoff point for the definition of sepsis. @*Conclusions@#Among cirrhosis patients presenting with infections at the ED, CLIF-SOFA scores showed a better predictive performance for mortality than both Sepsis-3 criteria and qSOFA scores, and can be a useful tool of risk stratification in cirrhotic patients requiring timely intervention for infection.

Change in Portal Pressure and Clinical Outcome in Cirrhotic Patients with Gastric Varices after Plug-Assisted Retrograde Transvenous Obliteration

Background/Aims@#Plug-assisted retrograde transvenous obliteration (PARTO) is widely used to manage gastric varices with a portosystemic shunt. It is not clear whether portal pressure and the incidence of complications increase after PARTO. The aim of this study was to determine the changes in portal pressure and the associated changes in liver func-tion, ascites, hepatic encephalopathy, and especially esopha-geal varix (EV) after PARTO. @*Methods@#From March 2012 to February 2018, 54 patients who underwent PARTO were analyzed retrospectively. The parameters collected included liver function and episodes of cirrhotic complications before and at 1 and 6 months after PARTO. @*Results@#The analysis of 54 patients showed improvement in liver function during the 6-month follow-up period (Model for End-Stage Liver Disease score: change from 11.46±4.35 to 10.33±2.96, p=0.021).Among these 54 patients, 25 patients were evaluated for their hepatic venous pressure gradient (HVPG) before and after PARTO (change from 12.52±3.83 to 14.68±5.03 mm Hg; p<0.001). Twenty-five patients with portal pressure mea-sured before and after PARTO were evaluated for risk factors affecting liver function improvement and EV deterioration. No factor associated with portal pressure was affected by liver function improvement. Post-PARTO portal pressure was a risk factor affecting EV deterioration (HVPG-post: odds ratio, 1.341; 95% confidence interval, 1.017 to 1.767; p=0.037). @*Conclusions@#The artificial blockade of the portosystemic shunt evidently leads to an increase in HVPG. Liver function was improved over the 6-month follow-up period. Portal pres-sure after PARTO was a significant risk factor for EV deterioration. Portal pressure measurement is helpful for predicting the patient’s clinical outcome.

An Esophageal Squamous Cell Carcinoma with Lymph Node Metastasis Presenting as a Small Subepithelial Tumor

A subepithelial tumor-like esophageal carcinoma is rare. We report a case of an esophageal squamous cell carcinoma with lymph node metastasis presenting as a small subepithelial tumor. A 68-year-old man presented to our hospital complaining of hoarseness since last three months. Endoscopic examination revealed a 1 cm hard and fixed subepithelial tumor with surface erosion in the lower esophagus. A biopsy specimen was obtained using conventional forceps, and histopathological evaluation revealed few atypical squamous epithelial cells. Subsequent EUS demonstrated a homogeneous hypoechoic lesion in the deep mucosal layer. A CT scan of the chest showed a 3 cm mass in the right upper paratracheal area. EUS-guided fine needle biopsy of the lesion led to the diagnosis of squamous cell carcinoma with lymph node metastasis.

Platelet count is associated with sustained virological response rates in treatments for chronic hepatitis C

BACKGROUND/AIMS@#This study was conducted to clarify the sustained virological response (SVR) prediction ability of baseline and treatment-related factors in patients with chronic hepatitis C virus (HCV) infection.@*METHODS@#This retrospective study collected data at four tertiary referral hospitals between June 2004 and July 2012. Out of 476 patients, 330 treatment-naïve patients with chronic HCV infection were recruited. Pegylated interferon α-2a/-2b plus ribavirin was administered for either 24 or 48 weeks depending on the HCV genotype. The baseline and treatment-related predictive factors of SVR were evaluated by analyzing data measured before treatment (i.e., baseline) and during treatment.@*RESULTS@#SVR rates for genotypes 1 and 2 were 63% (97/154) and 79.5% (140/176), respectively (p = 0.001). Multivariate analysis for baseline factors revealed that young age (p = 0.009), genotype 2 (p = 0.001), HCV RNA level of 150 × 10³/µL (p 150 × 10³/µL. In multivariate analysis for treatment-related factors, SVR was associated with achievement of a rapid virological response (RVR; p < 0.001), treatment adherence of ≥ 80/80/80 (p < 0.001).@*CONCLUSIONS@#Young age, genotype 2, low HCV RNA level, RVR, and treatment adherence were significantly associated with SVR. In addition, platelet count was an independent predictive factor for SVR. Therefore, platelet count could be used to develop individualized treatment regimens and to optimize treatment outcomes in patients with chronic HCV infection.

Usefulness of External Carotid Artery Angiogram with Manual Carotid Compression in Ophthalmic Artery Aneurysm

OBJECTIVE: Identifying collaterals from external carotid artery (ECA) is necessary before treatment of ophthalmic artery (OphA) aneurysm. We present a manual carotid compression test to verify collaterals in ophthalmic artery aneurysms, and evaluate its usefulness.MATERIALS AND METHODS: From March 2013 to December 2017, endovascular coiling was performed 19 consecutive patients with 20 OphA aneurysms. We performed manual carotid compression test for patients who had aneurysms incorporating entry of OphA. Clinical and angiographic outcomes were investigated.RESULTS: Of 13 cases underwent manual carotid compression test, 12 cases were confirmed collateral flow from ECA to OphA. During the coil embolization, we tried to maintain the original OphA flow even if it has a collateral anastomosis. Among them, OphA occlusion occurred in one patient during coiling. Recurrence of aneurysm was occurred in a ruptured case and additional embolization was required.CONCLUSIONS: The manual carotid compression test is useful method to identify the collaterals from ECA in patients with OphA aneurysm. This test can be used as a screening test for confirming collateral flow in OphA aneurysms or as an alternative for patients who are difficult to perform BTO.

Follow-up Creatinine Level Is an Important Predictive Factor of In-hospital Mortality in Cirrhotic Patients with Spontaneous Bacterial Peritonitis

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is one of the severe complications of liver cirrhosis. Early detection of high-risk patients is essential for prognostic improvement. The aim of this study is to investigate the predictive factors related to in-hospital mortality in patients with SBP. METHODS: This was a retrospective study of 233 SBP patients (181 males, 52 females) who were admitted to four tertiary referral hospitals between August 2002 and February 2013. The patients' laboratory and radiologic data were obtained from medical records. The Child-Turcotte-Pugh (CTP) score and model for end-stage liver disease sodium model (MELD-Na) scores were calculated using the laboratory data recorded at the time of the SBP episode. RESULTS: The causes of liver cirrhosis were hepatitis B (44.6%), alcohol (43.8%), hepatitis C (6.0%), and cryptogenic cirrhosis (5.6%). The mean MELD-Na and CTP scores were 27.1 and 10.7, respectively. Thirty-one of the patients (13.3%) died from SBP in hospital. Multivariate analysis revealed that maximum creatinine level during treatment was a statistically significant factor for in-hospital mortality (P = 0.005). The prognostic accuracy of the maximum creatinine level during treatment was 78.0% (P < 0.001). The optimal cutoff point for the maximum serum creatinine was 2 mg/dL (P < 0.001). CONCLUSION: The follow-up creatinine level during treatment is an important predictive factor of in-hospital mortality in cirrhotic patients with SBP. Patients with SBP and a serum creatinine level during treatment of ≥ 2.0 mg/dL might have a high risk of in-hospital mortality.

Usefulness of the procalcitonin test in young febrile infants between 1 and 3 months of age / 소아과

PURPOSE: To study the usefulness of the procalcitonin (PCT) test in young febrile infants between 1 and 3 months of age. METHODS: We evaluated the medical records of 336 febrile infants between 1 and 3 months of age who visited the Emergency Department or outpatient department of Samsung Changwon Hospital from May 2015 to February 2017, and analyzed the clinical characteristics between infants in the serious bacterial infection (SBI) group and non-SBI group. RESULTS: Among the 336 infants, 38 (11.3%) had definitive SBI (bacteremia, n=3; meningitis, n=1; urinary tract infection, n=34). The mean PCT (6.4±11.9 ng/mL) and C-reactive protein (CRP) level (3.8±2.6 mg/dL), and the absolute neutrophil count (ANC) (6,984±4,675) for patients in the SBI group were significantly higher than those for patients in the non-SBI group (PCT, 0.3±1.2 ng/mL; CRP, 1.3±1.6 mg/dL; ANC, 4,888±3,661). PCT had lower sensitivity (43.6%), but higher specificity (92.6%) and accuracy (86.9%) than CRP (92.3%, 25.3%, and 33.0%) for identifying SBI. The area under the receiver operating characteristic curves (AUCs) for definitive SBI were PCT 77.0%, CRP 80.8%, WBC 56.8%, ANC 67.8%, and PLT 48.1%. The AUCs for definitive SBI were PCT+CRP 85.4%, PCT+WBC 77.2%, PCT+ANC 81.3%, CRP+WBC 80.1%, and CRP+ANC 81.6%. CONCLUSION: Our results suggest that the PCT test or a combination of PCT and CRP tests is a more accurate and specific biomarker to detect and rule out SBIs.

Clinical significance of radiation-induced liver disease after stereotactic body radiation therapy for hepatocellular carcinoma

BACKGROUND/AIMS: The aim of this study was to investigate parameters that predict radiation-induced liver disease (RILD) following stereotactic body radiotherapy (SBRT) in patients with hepatocellular carcinoma (HCC) and to identify the clinical significance of RILD. METHODS: We retrospectively reviewed the medical records of 117 HCC patients who were treated by SBRT from March 2011 to February 2015. RILD was defined as elevated liver transaminases more than five times the upper normal limit or a worsening of Child-Pugh (CP) score by 2 within 3 months after SBRT. All patients were assessed at 1 month and every 3 months after SBRT. RESULTS: Median follow-up was 22.5 months (range, 3 to 56) after SBRT. RILD was developed in 29 of the 117 patients (24.7%). On univariate analysis, significant predictive factors of RILD were pretreatment CP score (p < 0.001) and normal liver volume (p = 0.002). Multivariate analysis showed that CP score was a significant predictor of RILD (p < 0.001). The incidence of RILD increased above a CP score of 6 remarkably. The rate of recovery from RILD decreased significantly above a CP score of 8. Survival analysis showed that CP score was an independent prognostic factor of overall survival (p = 0.001). CONCLUSIONS: CP score is a significant factor to predict RILD in patients with chronic liver disease. RILD can be tolerated by patients with a CP score ≤ 7. However, careful monitoring of liver function is needed for patients with a CP score 7 after SBRT.

A Case of Small Hepatocellular Carcinoma Who Showed Complete Response by Combined Therapy of Transarterial Chemoembolization and Stereotactic Body Radiotherapy

In hepatocellular carcinoma (HCC), surgical resection or local ablation therapy is limited because of severe liver dysfunction or tumor location. Transarterial chemoembolization (TACE) has beed used widely as palliative treatment. Stereotactic Body Radiotherapy (SBRT) is a more recent and effective treatment for early stage HCC. We report a case with small HCC with complete response by TACE combined with SBRT.

Interrater Reliability among Endoscopists: Diagnosis of Laryngopharyngeal Reflux Based on the Reflux Finding Score Determined by Upper Endoscopy

BACKGROUND/AIMS: Laryngopharyngeal reflux (LPR) is an extraesophageal manifestation of gastroesophageal reflux disease. Endoscopic assessment of LPR is needed for convenient diagnosis and documentation of treatment efficacy. The aim of this study was to investigate the interrater reliability of LPR among endoscopists based on endoscopic laryngeal images. MATERIALS AND METHODS: Nineteen endoscopists participated in this study. Before the test, they completed an intensive education program by an otorhinolaryngologist on the reflux finding score (RFS), which is a validated laryngoscopic assessment of LPR. A total of 100 endoscopic laryngeal images were used for 3 tests of RFS. Cohen's and Fleiss' kappa coefficients were used to determine the degree of interrater agreement in the diagnosis of LPR. RESULTS: In the first test, the mean of Cohen's kappa coefficients for LPR diagnosis between the otorhinolaryngologist and each of the 19 endoscopists was 0.3. In the second test, after additional education, the mean kappa value was 0.32. Fleiss' kappa coefficients for diagnosis of LPR among the 19 endoscopists in the first and second tests were 0.30 and 0.26, respectively. CONCLUSIONS: A short-term education program for endoscopists did not result in an improvement of accuracy in the diagnosis of LPR. Further studies using advanced educational programs for endoscopists are required.

Mucosal Incision and Forceps Biopsy for Reliable Tissue Sampling of Gastric Subepithelial Tumors

BACKGROUND/AIMS: The diagnostic efficacy of current tissue sampling techniques for gastric subepithelial tumors (SETs) is limited. Better tissue sampling techniques are needed to improve pathological diagnosis. The aim of this study was to evaluate the safety and efficacy of a new technique, mucosal incision and forceps biopsy, for reliable tissue sampling of gastric SETs. METHODS: This study enrolled 12 consecutive patients who underwent mucosal incision and forceps biopsy of gastric SETs between November 2011 and September 2014 at Gangneung Asan Hospital. The medical records of patients were reviewed retrospectively. The safety and diagnostic yield of this method were evaluated. RESULTS: By performing mucosal incision and forceps biopsy, we were able to provide a definitive histological diagnosis for 11 out of 12 cases. The pathological diagnoses were leiomyoma (3/11), gastrointestinal stromal tumor (GIST; 2/11), lipoma (2/11), schwannoma (1/11), and ectopic pancreas (3/11). In cases of leiomyoma (n=3) and GIST (n=2), tissue samples were of sufficient size to allow immunohistochemical staining. In addition, the mitotic index was evaluated in two cases of GIST. There were no procedure-related complications. CONCLUSIONS: Mucosal incision and forceps biopsy can be used as one of several methods to obtain adequate tissue samples from gastric SETs.

Kawasaki Disease Shock Syndrome with Acute Kidney Injury and Hypertension

Kawasaki disease (KD) is an acute febrile mucocutaneous lymph node syndrome that commonly presents with stable hemodynamic status during the acute phase. An 8-year-old boy initially presented with severe hypotension and acute kidney injury. He was placed in the intensive care unit and was diagnosed with KD. Observed clinical features were defined as KD shock syndrome. His coronary artery was dilated during the subacute phase. Furthermore, he was given anti-hypertensive medications, owing to hypertension as an unusual complication of KD. We knew the importance of monitoring for blood pressure considering vasculitis as an aspect of the main pathogenesis of KD.

A Case of Cecal Endometriosis Presenting as Subepithelial Tumor / 대한소화기학회지

Endometriosis is a benign gynecologic disease, characterized by the presence and growth of functional endometrial-like tissue outside uterus. This ectopic endometrial tissue is most commonly found in the peritoneum, ovaries and uterosacral ligaments, but extremely rarely there is involvement of the appendix or cecum. Here we report a case of cecal endometriosis presenting as a subepithelial tumor diagnosed by surgical excision.

Clinical Significance of Newborn Gastric Inflammatory Mediators

PURPOSE: We performed this study to determine (1) whether the levels of inflammatory mediators, including matrix metalloproteinase-9 (MMP-9) and intercellular adhesion molecule-3 (ICAM-3), in gastric fluid (GF) in premature newborns are associated with those in amniotic fluid (AF) in their mothers and (2) whether the levels of the inflammatory mediators in newborn GF are associated with the presence of intrauterine inflammation (IUI). METHODS: Sixty-two pairs of pregnant women and their premature newborns born at <35 weeks' gestation by cesarean delivery were enrolled in this study. AF and newborn GFs were obtained during cesarean section procedures. Levels of MMP-9, ICAM-3, interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-alpha (TNF-alpha) were measured and compared between the AF and newborn GFs in each dyad, according to the presence or absence of chorioamnionitis (CA), preterm prelabor rupture of membranes (PPROM), and preterm labor (PTL). RESULTS: The levels of MMP-9, ICAM-3, IL-6, IL-8, and TNF-alpha in newborn GF were significantly correlated with those in AF in each dyad. The premature newborns and their mothers with CA had significantly higher GF MMP-9, IL-8, and TNF-alpha levels than those without CA. Those with PPROM or PTL showed similar findings in terms of GF MMP-9, IL-8, and TNF-alpha levels. CONCLUSION: The newborn GF immediately after birth can be a useful alternative source of information on whether a premature infant has been exposed to IUI at the time of delivery.

Spontaneous Rupture of Pancreatic Mucinous Cystadenocarcinoma: A Case Report and Review of Literature / 대한췌담도학회지

The pancreatic cystic lesions are known to be incidentally found up to 10-15% of patients undergoing cross-sectional imaging. And the prevalence of mucinous cystic neoplasm which has malignant potential is known to be up to 25% of all pancreatic cystic neoplasm in South Korea. The symptoms included abdominal pain, palpable mass, weight loss, loss of appetite, jaundice, asymptomatic and etc. However, spontaneous rupture of pancreatic mucinous cystadenocarcinoma (MCAC) is an extremely rare complication. Here we report a case of spontaneous rupture of pancreatic MCAC in a 72-year-old male with review of the literature. To the best of our knowledge, this is the first ruptured case of pancreatic MCAC in male patient.

Enoxaparin Therapy for Arterial Thrombosis After Umbilical Cord Catheterization in Preterm Infants

The incidence of symptomatic thrombosis of umbilical arterial catheterization is 1-3%. Therapeutic options may include: using heparin or low molecular weight heparin, using a thrombolytic agent, or surgical thrombectomy. However, there are insufficient data to recommend any one treatment over the others. Recently, enoxaparin, a low molecular weight heparin, has emerged as a drug of choice for the treatment of neonatal thrombosis due to pharmacologic stability over unfractionated heparin or thrombolytic agents. We report a case of successful treatment of aortic thrombosis after umbilical arterial catheterization with enoxaparin in preterm infants.

Relationship between 25-Hydroxyvitamin D Levels and Liver Fibrosis as Assessed by Transient Elastography in Patients with Chronic Liver Disease

BACKGROUND/AIMS: Deficiencies of 25-hydroxyvitamin D (25(OH)D) are prevalent in patients with chronic liver disease (CLD). Liver fibrosis is the main determinant of CLD prognosis. The present study was performed to evaluate the correlation between 25(OH)D levels and liver fibrosis as assessed by transient elastography (TE) in patients with compensated CLD. METHODS: Serum 25(OH)D levels and liver stiffness were determined in a total of 207 patients who were subjected to the following exclusion criteria: patients with decompensated CLD; patients who had malignancies; patients who were taking medications; and patients who were pregnant. RESULTS: The most common etiology was chronic hepatitis B (53.1%). Advanced liver fibrosis (defined by TE [≥9.5 kPa]) was present in 75 patients (36.2%). There was a significant correlation between 25(OH)D deficiency and liver stiffness. Based on the multivariate analysis, the following factors were independently associated with advanced liver fibrosis: 25(OH)D deficiency (odds ratio [OR], 3.46; p=0.004), diabetes mellitus (OR, 3.04; p=0.041), and fibrosis-4 index (OR, 2.01; p<0.001). CONCLUSIONS: Patients with compensated CLD exhibit a close correlation between vitamin D level and liver stiffness as assessed by TE. Vitamin D deficiency was independently associated with advanced liver fibrosis.

Predictive Factors for Sustained Remission after Discontinuation of Antiviral Therapy in Patients with HBeAg-positive Chronic Hepatitis B / 대한소화기학회지

BACKGROUND/AIMS: The optimal timing for discontinuing oral antiviral therapy in patients with HBeAg-positive chronic hepatitis B (CHB) is unclear. The aim of our study was to investigate sustained remission after stopping antiviral therapy in patients with HBeAg-positive CHB. METHODS: We analyzed the medical records of 58 patients who were HBeAg-positive and had discontinued antiviral therapy. Antiviral therapy was discontinued after HBeAg seroconversion and HBV DNA negativity for 6-12 months with consolidation therapy. Virologic relapse was defined as an increase in serum HBV DNA >2,000 IU/mL. RESULTS: No difference was observed between the virologic non-relapse and virologic relapse groups in baseline HBV DNA level (p=0.441) or duration of seroconversion (p=0.070). Time-to-undetectable HBV DNA during treatment was shorter in the virologic non-relapse group (29 patients) compared to the relapse group (29 patients) (4.9+/-2.6 vs. 13.2+/-12.7 months; p or =18 months, p=0.020) and early virologic response (HBV DNA <20 IU/mL) at six months during antiviral therapy (p=0.017) were significant predictors for sustained remission. CONCLUSIONS: A consolidation period of at least 18 months and early virological response at six months during antiviral therapy were associated with sustained remission in patients with HBeAg-positive CHB after treatment.
