Background/Aims@#This study evaluated the incidence of venous thromboembolism (VTE) in patients with advanced pancreatic ductal adenocarcinoma (PDAC) at the authors’ institution and analyzed the risk factors associated with VTE and the overall survival (OS). @*Methods@#One hundred and seventy patients with locally advanced or metastatic PDAC who received palliative chemotherapy at Daegu Catholic University Medical Center from January 2011 to December 2020 were included. @*Results@#During a median follow-up period of 341 days, 24 patients (14.1%) developed VTE. Cumulative incidence values of VTE were 4.7% (95% confidence interval [CI], 2.39-9.22) at 90 days, 9.9% (95% CI, 6.14-15.59) at 180 days, and 16.9% (95% CI, 11.50-24.36) at 360 days. Multivariate analysis showed that a carbohydrate antigen 19-9 (CA 19-9) level over 1,000 U/mL (hazard ratio [HR], 2.666; 95% CI, 1.112-6.389; p=0.028) and a history of alcohol consumption (HR, 0.327; 95% CI, 0.109-0.981; p=0.046) were significant factors associated with VTE. Patients with VTE showed a shorter median survival (347 days vs. 556 days; p=0.041) than those without VTE. Multivariate analysis revealed VTE (HR, 1.850; 95% CI, 1.049-3.263; p=0.033) and CA 19-9 level over 1,000 U/mL (HR, 1.843;95% CI, 1.113-3.052; p=0.017) to be significant risk factors associated with OS. @*Conclusions@#The cumulative incidence of VTE in patients with advanced PDAC was 16.9% at 360 days. While a history of alcohol consumption was a protective factor, a high CA19-9 level was a risk factor for VTE. In addition, the occurrence of VTE was associated with poor prognosis.

Background/Aims@#Increasing resistance to clarithromycin (CAM) of Helicobacter pylori (H. pylori) is one of the main causes of recent decrease in eradication rate of standard triple therapy. The aim of this study was to evaluate the usefulness of 7-day tailored therapy based on the existence of CAM resistance. @*Methods@#From January 2017 to May 2022, a total of 481 consecutive patients with H. pylori infection were recruited in Daegu Catholic University Medical Center. Treatment regimen was selected based on the result of CAM resistance test. Patients with CAM resistance (R group) were treated with bismuth-based quadruple therapy for 7 days. Patients without CAM resistance (S group) were treated with standard triple therapy for 7 days. @*Results@#The overall H. pylori eradication rate was 89.4% (379 of 424) by per-protocol (PP) analysis. Patients with CAM resistance mutation included 166 patients (34.5%). The eradication rates of each group were 88.8% (135 of 152) and 89.7% (244 of 272) by PP analysis, for R and S group respectively. By intention-to-treat (ITT) analysis, the eradication rates were 81.3% (135 of 166) and 77.5% (244 of 315) for R and S group. CAM resistance was identified with a dual-priming oligonucleotide-based multiplex PCR. @*Conclusions@#In spite of this high CAM resistance (34.5%), the eradication rate of 7-day tailored therapy based on the existence of CAM resistance was 89.4%. The 7-day tailored therapy based on CAM resistance could be an acceptable treatment selection strategy for H. pylori eradication.

The prognosis for pancreatic cancer is still poor with a 5-year survival rate around 10%. We report a case of complete remission after palliative chemotherapy for pancreatic cancer in a 61-year-old-female. She presented with indigestion and weight loss. A computed tomography scan revealed a 1.8 cm mass in the pancreatic head. Carbohydrate antigen 19-9 (CA 19-9) and carcinoembryonic antigen (CEA) levels were elevated. The patient underwent endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) and the pathologic examination showed adenocarcinoma. Positron emission tomography (PET) and magnetic resonance imaging (MRI) of the pancreas showed a metastatic nodule in the S6 segment of the liver and a metastatic portocaval lymph node. The final diagnosis was stage IV pancreatic cancer. The patient received 24 cycles of palliative FOLFIRINOX regimen. Response evaluation demonstrated disappearance of all the lesions. She underwent pyloruspreserving pancreatoduodenectomy (PPPD). The pathologic examination of the surgical specimen showed complete remission of the pancreatic cancer. The patient is currently undergoing adjuvant chemotherapy.

Lactococcus garvieae is a Gram-positive cocci that has been known to be a fish pathogen, and considered as a low virulence organism rarely associated with human infection. We report a case of acute cholangitis with common bile duct (CBD) stone and bacteremia by L. garvieae bacteremia in a 70-year-old male. The patient presented with epigastric pain and was diagnosed with two CBD stones. Blood culture obtained prior to empiric antimicrobial therapy with ceftizoxime sodium showed growth with Escherichia coli and L. garvieae. The bacteria were confirmed by matrix-assisted desorption/ionization time-of-flight mass spectrometry. Initial attempt at endoscopic biliary drainage failed, and the patient underwent percutaneous transhepatic biliary drainage and subsequent stone removal. He occasionally ingested raw fish and had a history of gastric ulcer with acid suppression therapy, which could be possible risk factors for L. garvieae infection. This is the first case of L. garvieae bacteremia in acute cholangitis.
