Efficacy of Vonoprazan for 48-Week Maintenance Therapy of Patients with Healed Reflux Esophagitis.

AIMS: We aimed to evaluate the efficacy of vonoprazan (VPZ) as maintenance therapy for healed reflux esophagitis (RE). METHODS: We enrolled 74 patients diagnosed with RE with frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) total score ≥8 after at least 8 weeks of treatment with standard proton pump inhibitors (PPIs). These patients were switched to VPZ 20 mg for 4 weeks. We also enrolled 71 patients with no endoscopic evidence of erosive esophagitis who received maintenance therapy with VPZ 10 mg for 48 weeks. The primary end point was the proportion of patients who maintained healed RE refractory to PPIs after 48 weeks of maintenance therapy with on demand 10 mg VPZ. Secondary assessment included the proportion of patients with symptomatic nonrelapse at 48 weeks. RESULTS: Fifty patients successfully completed 48-week maintenance therapy. Maintenance therapy with VPZ 10 mg prevented the relapse of esophageal mucosal breaks in 43 (86.0%) of 50 patients at 48 weeks. During the 48-week maintenance therapy, symptomatic nonrelapse rate for acid reflux-related symptom score of FSSG and acid reflux score of Gastrointestinal Symptom Rating Scale at 48 weeks were 70.0 and 72.0%, respectively. No serious adverse events were reported during the study. CONCLUSION: VPZ 10 mg is clinically effective for maintenance of healed RE for 48 weeks.

Treatment patterns and outcomes of unresectable pancreatic cancer patients in real-life practice: a region-wide analysis.

BACKGROUND: FOLFIRINOX (FFX) and gemcitabine (GEM) plus nab-paclitaxel (GnP) have recently been available for treating pancreatic ductal adenocarcinoma (PDAC). We investigated trends in characteristics, treatment and outcomes of unselected patients with unresectable PDAC in real-life practice in Japan. METHODS: We retrospectively reviewed the medical records of 1085 patients diagnosed as having unresectable or recurrent PDAC in multiple centers in the Hokuriku area between January 2009 and July 2015. RESULTS: The incidence of pathologically proven PDAC had increased from 18.7% in 2009 to 56.2% in 2015. Oncological therapy was administered to 779 patients (71.8%): chemotherapy (n = 675), chemo-radiotherapy (n = 92) or radiotherapy (n = 12); the remaining patients were treated with best supportive care. Of 100 patients diagnosed in 2009, 62.0% received GEM as first-line chemotherapy; whereas 30.7% of the 75 patients diagnosed in 2015 received FFX, 25.3% GnP, 22.7% GEM and 17.3% S-1. The objective response rates of patients treated with FFX, GnP and GEM were 14.9%, 35.0% and 5.5%, respectively and the OS 10.3, 9.9 and 7.5 months after FFX, GnP and GEM, respectively. Grade 3 or greater any hematological toxicity occurred in 70.2%, 70.0% and 18.8% of the patients treated with FFX, GnP and GEM, respectively. The reasons for treatment discontinuation were adverse events in 9.8%, 26.7% and 24.1% of the patients treated with FFX, GnP and GEM, respectively. CONCLUSION: Chemotherapeutic protocols changed dramatically between 2009 and 2015. Continuous collection and analysis for our cohort with longer follow-up provides useful information about treatment selection and prediction of outcome.

[Effect of Japanese Traditional Medicine, Ninjin-Youei-To(TJ-108), on the Quality of Life of Patients with Non-Small Cell Lung Cancer Receiving Outpatient Chemotherapy].

An increasing number of patients with lung cancer are undergoing outpatient chemotherapy, and thus, it is very important to maintain the quality of life(QOL)of these patients. Ninjin-Youei-To(TJ-108), a Japanese traditional medicine, has been reported to improve the QOL of patients with advanced cancer. However, the effect of TJ-108 in patients with lung cancer undergoing outpatient chemotherapy is unknown. Therefore, we conducted this study. To investigate factors influencing the QOL of these patients, we administered a QOL questionnaire,"The QOL Questionnaire for Cancer Patients Treated with Anticancer Drugs"(QOL-ACD)to 15 patients with non-small cell lung cancer. Factors related to the overall QOL scores and other categories indicating"activity","physical condition","psychological condition","social relationship", and"face scale" were analyzed. No significant decrease in each of the evaluated factors was observed in this study.

Efficacy of vonoprazan for 24-week maintenance therapy of patients with healed reflux esophagitis refractory to proton pump inhibitors.

The aim of the present study was to evaluate the efficacy of a potassium-competitive acid blocker (P-CAB), vonoprazan, for the maintenance therapy of healed reflux esophagitis (RE). A total of 60 patients were enrolled in this open-label, single-center, prospective study. All patients were diagnosed with RE with a frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) total score ≥8 following treatment with standard proton pump inhibitors (PPIs) for a minimum of 8 weeks. Standard PPI treatment was switched to vonoprazan 20 mg once daily for 4 weeks. A total of 52 patients, who had no endoscopic evidence of erosive esophagitis following vonoprazan treatment, received maintenance therapy with vonoprazan 10 mg once daily for 24 weeks. Symptoms were evaluated using the FSSG and Gastrointestinal Symptom Rating Scale (GSRS). Upper gastrointestinal endoscopies were performed following 24 weeks of maintenance therapy. The primary endpoint was to determine the proportion of patients who exhibited maintenance of healed RE refractory to PPIs following 24 weeks of maintenance therapy with vonoprazan 10 mg once daily. Secondary endpoints included evaluation of the proportion of patients with symptomatic non-relapse at 24 weeks. Maintenance therapy with vonoprazan 10 mg once daily prevented relapse of esophageal mucosal breaks in 37/43 (86.0%) patients at 24 weeks. However, the number of patients with symptomatic relapse was 1 (1.9%) and 4 (7.7%) at 4 and 8 weeks, respectively. A total of 4 patients were withdrawn due to loss to follow-up. At the end of the 24-week maintenance period, the symptomatic non-relapse rate for acid reflux-associated and dysmotility symptom FSSG scores were 86.5 and 80.8%, respectively. Furthermore, the symptomatic non-relapse rate for reflux, abdominal pain, indigestion, diarrhea, and constipation GSRS scores at 24 weeks were 86.5, 80.8, 75.0, 71.2 and 76.9%, respectively. No serious adverse events were reported during the study. The mean gastrin level was 1,059 pg/ml. In conclusion, the results of the present study indicate that vonoprazan 10 mg once daily is effective for 24-week maintenance therapy of healed RE refractory to PPIs.

[Successful treatment of enterohemorrhagic Escherichia coli O111-induced hemolytic-uremic syndrome and acute encephalopathy].

We report a case of a woman in her twenties with enterohemorrhagic Escherichia coli O111-induced hemolytic-uremic syndrome who developed acute encephalopathy on day 5 of admission. She recovered after treatment with steroid pulse therapy, plasmapheresis, and recombinant thrombomodulin, without any adverse sequelae. We report this interesting case and provide a summary of the recent outbreak of enterohemorrhagic Escherichia coli O111.

[Nab-Paclitaxel with platinum chemotherapy as sixth-line therapy for a non-small cell lung cancer patient].

A 48-year-old woman was admitted to our hospital for sixth-line chemotherapy. A chest X-ray film and computed tomographic (CT) scan revealed a right-sided massive tumor with multiple lung tumors. Repeated treatment with carboplatin (AUC 6) on day 1 and nab-paclitaxel (100mg/m2) on days 1, 8, and 15, every 28 days were effective in this patient. Chemotherapy with nab-paclitaxel may be effective for patients with multi-recurrent adenocarcinoma.

[Analysis of factors associated with the quality of life in patients with non-small cell lung cancer who received outpatient pemetrexed maintenance therapy].

Increasing number of patients with advanced non-small cell lung cancer are receiving outpatient maintenance chemotherapy. It is very important to maintain these patients' quality of life(QOL). Pemetrexed has been reported to be an effective maintenance chemotherapy. However, its effects on the QOL of patients with non-small cell lung cancer who are undergoing outpatient maintenance chemotherapy are unknown; therefore, we conducted this study. To investigate factors that influence the QOL of these patients, we provided a QOL questionnaire,"The QOL Questionnaire for Cancer Patients Treated with Anticancer Drugs(QOL-ACD)"to 7 patients with non-small cell lung cancer. The medical factors related to the overall QOL scores, as well as other categories indicating"activity","physical condition","psychological condition","social relationship", and"face scale", were analyzed. No significant reductions in any of the factors were observed in this study.

Successful endoscopic management of fish bone embedded into the bladder wall.

We report a case of a pyogenous vesical abscess resulting from an ingested fish bone embedded in the bladder wall that was treated endoscopically in an asymptomatic man. Computed tomography of the abdomen showed a linear radiopaque structure in the thickened left anterolateral wall of the bladder. Cystoscopy revealed a protruding mass, covered with normal-appearing mucosa, with outflow of pus from a shallow recess. Histopathological findings indicated that the transurethrally removed linear structure, located in the submucosa, was compatible with fish bone. A high index of suspicion should be maintained for the correct diagnosis to be made.

Liver sarcoidosis that presented with dysphagia.

We report a case of liver sarcoidosis with dysphagia. Although akinesia of the soft palate, disappearance of the palatal reflex, and pyramidal signs indicated brainstem lesions, brain magnetic resonance imaging showed no lesion and the focus was obscure. Iritis, parotiditis, and hilar lymphadenopathy supported the diagnosis of sarcoidosis. However, lung biopsy was normal. Finally, sarcoidosis was diagnosed by liver biopsy. We speculated that microgranulomas in the brainstem that did not exhibit imaging abnormalities causing the neurological symptoms and that liver biopsy can be an effective diagnostic tool even for cases that presented with neurological signs, but no gastrointestinal symptom.
