A 77-year-old woman underwent endovascular abdominal aortic repair (EVAR) for an abdominal aortic aneurysm (AAA).Five years after surgery, she visited the hospital with the chief complaint of a fever. Enhanced computed tomography (CT) showed enlargement of the AAA around the stent-graft and a mass, which was suspected to be an abscess, outside the aneurysm. A blood test revealed a high level of inflammatory response. The patient was diagnosed with infectious AAA. She received antibiotics; however, the inflammatory response did not completely improve. A second CT scan revealed that the suspected abscess had a spreading tendency. The patient was referred to our hospital for a highly suspected stent-graft infection. We performed Y-graft replacement using a rifampicin-immersed graft, and as much as possible of the wall around the aortic aneurysm was removed. The inflammatory response improved rapidly after the operation, and the patient was discharged 15 days later. According to the results of a pathological examination, a diagnosis of xanthogranulomatous inflammation and fibrosis was made. Here, we report a rare case of xanthogranulomatous inflammation of the aortic aneurysm wall after EVAR.

Purpose: This study aimed to investigate the current status and related factors of End of Life discussions between heart failure patients and medical professionals. Method: We conducted a survey of medical records of patients who died between April 2015 and March 2020 in the Department of Cardiology, Kyoto University Hospital. We examined the presence or absence of discussions about prognosis and end-of-life care and their associated factors. Result: Of the 109 patients, prognosis was explained to 40 (36.7%) and discussion of end-of-life care was provided to 25 (22.9%). Age (younger), number of hospitalizations, palliative care team intervention, and end-of-life care discussions were associated with the prognostic explanations. Gender (male), number of hospitalizations, history of heart failure hospitalization, palliative care team intervention, and prognosis explanation were associated with the end-of-life care discussions. Conclusion: The study suggested that End of Life discussions in heart failure patients are currently focused on patients with severe and end-stage heart failure.

Although the descriptions of shigyakukachotanto in “Waitaimiyaofang” and tsumyakushigyakukachotanjuto in “Songban Shanghanlun” are quite similar to each other, the specifications of the dosages of crude drugs and the water volume in the books were considerably different. Focused on the specified water volume to decoct these formulas, each reasonable decocting period was estimated, then the decoctions were prepared using hard water that was common in mainland China. The dosages of aconite root were 2-fold different between these two formulas, but the contents of aconitine-type diester alkaloids (ADA) in both decoctions were found in the range of 1.2—1.4-fold. It was suggested that in order to control the efficacy and the safety of aconite, the decocting period was well regulated by the specification of water volume for decocting at this ancient era. Moreover, the dosages of aconite root and glycyrrhiza in bukuryoshigyakuto (BSGT) formula of “Songban Shanghanlun” are equal to those of shigyakuto (SGT) but the specified water volume to begin decocting is as about twice as that of SGT. When prepared using hard water, BSGT resulted to make the contents of ADA lower and those of non-ester alkaloids higher compared with those of SGT decoction. It was suggested the specific water volume for each formula prescribed in classical Chinese medicine had considerable significance to determine the dosages of chemical ingredients in the decoctions especially in the circumstances using hard water to prepare them.

BACKGROUND/AIMS: Although daclatasvir with asunaprevir was approved in Japan for interferon ineligible or intolerant patients, patients aged ≥75 years were excluded in the phase III trial. The present study aimed to evaluate the safety and efficacy of this therapy for elderly patients aged ≥75 years and to clarify whether an extremely high sustained virological response (SVR) rate can be achieved, even in a real-world setting when patients with resistance-associated substitutions (RASs) to nonstructural protein 5A (NS5A) inhibitors or prior simeprevir failure are excluded. METHODS: Daclatasvir (60 mg) and asunaprevir (100 mg) were orally administered daily for 24 weeks. Patients without pre-existing NS5A RASs and simeprevir failure were enrolled in this study. RESULTS: Overall, 110 patients were treated. The median age was 73 years old. The SVR rates of total patients, those aged ≥75 years, and those aged < 75 years were 97% (107/110), 98% (46/47), and 97% (61/63), respectively. The treatment of two patients (2%) was discontinued because of adverse events. CONCLUSIONS: Daclatasvir with asunaprevir was a safe treatment, even in patients aged ≥75 years. When patients without pre-existing NS5A RASs and prior simeprevir failure were selected, an extremely high SVR rate could be achieved irrespective of age.

The decoctions of unprocessed aconite root (uzu) were prepared with the tap water samples collected in Tianjin and Shanghai in China, and the contents of alkaloids in the decoctions were compared to those prepared with purified water or with tap water collected in Niigata, Japan. The contents of aconitine-type diester alkaloids (ADA) in the decoctions prepared with tap water collected in China were significantly lower than those with purified water or tap water in Niigata. It was speculated that this difference appeared by buffering effect of bicarbonic anion in tap water in China to decline pH of the decoction. When uzu was decocted with glycyrrhiza, ginger, or jujube, the contents of ADA in the decoctions exhibited the tendency to have higher levels than those prepared using unprocessed aconite root singly, and also this tendency was observed more remarkably when the decoctions were prepared with tap water collected in China. It was suggested that even the decocting period was fixed, unexpected change of the contents of ADAs might be induced by the differences in the properties of water used for decoction or the crude drugs decocted with aconite root. The physicians in the era when “Songban Shanghanlun” had established may have adjusted the contents of ADA in the decoction by carefully choosing the crude drugs combined to aconite root.

BACKGROUND/AIMS: The present study aimed to evaluate the safety and efficacy of simeprevir-based triple therapy with reduced doses of pegylated interferon (PEG-IFN) and ribavirin for interferon (IFN) ineligible patients, such as elderly and/or cirrhotic patients, and to elucidate the factors contributing to a sustained virologic response (SVR). METHODS: One hundred IFN ineligible patients infected with genotype 1b hepatitis C virus (HCV) were treated. Simeprevir (100 mg) was given orally together with reduced doses of PEG-IFN-α 2a (90 μg), and ribavirin (200 mg less than the recommended dose). RESULTS: The patients’ median age was 70 years, and 70 patients were cirrhotic. Three patients (3%) discontinued treatment due to adverse events. The SVR rate was 64%. Factors that significantly contributed to the SVR included the γ-glutamyl transferase and α-fetoprotein levels, interleukin-28B (IL28B) polymorphism status, and the level and reduction of HCV RNA at weeks 2 and 4. The multivariate analysis showed that the IL28B polymorphism status was the only independent factor that predicted the SVR, with a positive predictive value of 77%. CONCLUSIONS: Simeprevir-based triple therapy with reduced doses of PEG-IFN and ribavirin was safe and effective for IFN ineligible patients infected with genotype 1b HCV. IL28B polymorphism status was a useful predictor of the SVR.

BACKGROUND/AIMS: Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) has been used to diagnose gastrointestinal submucosal tumors (SMTs). Although rapid on-site evaluation (ROSE) has been reported to improve the diagnostic accuracy of EUS-FNA for pancreatic lesions, on-site cytopathologists are not routinely available. Given this background, the usefulness of ROSE by endosonographers themselves for pancreatic tumors has also been reported. However, ROSE by endosonographers for diagnosis of SMT has not been reported. The aim of this study was to evaluate the diagnostic accuracy of EUS-FNA with ROSE by endosonographers for SMT, focusing on diagnosis of gastrointestinal stromal tumor (GIST), compared with that of EUS-FNA alone. METHODS: Twenty-two consecutive patients who underwent EUS-FNA with ROSE by endosonographers for SMT followed by surgical resection were identified. Ten historical control subjects who underwent EUS-FNA without ROSE were used for comparison. RESULTS: The overall diagnostic accuracy for SMT was significantly higher in cases with than without ROSE (100% vs. 80%, p=0.03). The number of needle passes by FNA with ROSE by endosonographers tended to be fewer, although accuracy was increased (3.3±1.3 vs. 5.9±3.8, p=0.06). CONCLUSIONS: ROSE by endosonographers during EUS-FNA for SMT is useful for definitive diagnosis, particularly for GIST.

BACKGROUND/AIMS: Transpapillary forceps biopsy is an effective diagnostic technique in patients with biliary stricture. This prospective study aimed to determine the usefulness of the wire-grasping method as a new technique for forceps biopsy. METHODS: Consecutive patients with biliary stricture or irregularities of the bile duct wall were randomly allocated to either the direct or wire-grasping method group. In the wire-grasping method, forceps in the duodenum grasps a guide-wire placed into the bile duct beforehand, and then, the forceps are pushed through the papilla without endoscopic sphincterotomy. In the direct method, forceps are directly pushed into the bile duct alongside a guide-wire. The primary endpoint was the success rate of obtaining specimens suitable for adequate pathological examination. RESULTS: In total, 32 patients were enrolled, and 28 (14 in each group) were eligible for analysis. The success rate was significantly higher using the wire-grasping method than the direct method (100% vs 50%, p=0.016). Sensitivity and accuracy for the diagnosis of cancer were comparable in patients with the successful procurement of biopsy specimens between the two methods (91% vs 83% and 93% vs 86%, respectively). CONCLUSIONS: The wire-grasping method is useful for diagnosing patients with biliary stricture or irregularities of the bile duct wall.

BACKGROUND/AIMS: This study aimed to predict sustained viral response (SVR) to low-dose pegylated interferon (PEG-IFN) plus ribavirin of elderly and/or cirrhotic patients with genotype 2 hepatitis C virus (HCV) using viral response within 2 weeks. METHODS: Low-dose PEG-IFN-α-2b plus ribavirin was administered to 50 elderly and/or cirrhotic patients with genotype 2 HCV for 24 weeks. The dynamics of HCV RNA and HCV core antigen levels within 2 weeks were measured. RESULTS: The patients' median age was 66 years. There were 21 male and 29 female patients. The median baseline HCV RNA level was 5.7 log IU/mL. Rapid viral response was achieved in 17 patients (34%), SVR in 28 (56%), and two (4%) discontinued treatment. Univariate analysis of factors contributing to SVR showed significant differences for sex, baseline virus level, and response within 4 weeks. When 40 fmol/L was set as the cutoff value for the core antigen level at 1 week, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for predicting SVR were 93%, 75%, 84%, 88%, and 85%, respectively. CONCLUSIONS: Low-dose PEG-IFN plus ribavirin was a safe and cost-effective treatment for elderly and/or cirrhotic patients with genotype 2 HCV, and the viral response within 2 weeks was a useful predictor of SVR.

BACKGROUND/AIMS: The present study aimed to clarify whether virological response within 2 weeks after therapy initiation can predict a null response to pegylated interferon alpha-2b plus ribavirin therapy in patients with high viral load genotype 1b hepatitis C. METHODS: The participants consisted of 72 patients with high viral load genotype 1b. The dynamics of viral load within 2 weeks were measured. RESULTS: Significant differences between null responders and nonnull responders were noted for interleukin (IL)-28B genotype, amino acid 70 substitution, alpha-fetoprotein, low-density lipoprotein cholesterol, hyaluronic acid, and viral response. The area under the curve (AUC) for the receiver operating characteristic curve of the hepatitis C virus (HCV) RNA level decline at 2 weeks (AUC=0.993) was the highest among the factors predicting the null response. When the cutoff value for the HCV RNA level decline at 2 weeks was set at 0.80 log, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in predicting a null response were 82%, 96%, 82%, 96%, and 94%, respectively. In comparison, values for the non-TT and mutant type of amino acid 70 substitution were similar to those for HCV RNA level decline at 2 weeks. CONCLUSIONS: Virological response at 2 weeks or the combination of IL-28B and amino acid 70 substitution are accurate predictors of a null response.
