RESUMO

Background and aim: In patients with chronic hepatitis C, 8 weeks of glecaprevir and pibrentasvir (GLE/PIB) treatment for chronic hepatitis (non-cirrhosis) and 12 weeks for cirrhosis have been approved in Japan. However, whether 8 weeks of treatment for cirrhosis may reduce treatment efficacy has not been adequately investigated. Methods: This prospective, nationwide, multicenter cohort study enrolled 1275 patients with chronic hepatitis C who received GLE/PIB therapy. The effect of liver fibrosis and treatment periods on the efficiency of GLE/PIB therapy was investigated. The primary endpoint was the sustained virological response (SVR) rate in patients with chronic hepatitis (non-cirrhosis) and cirrhosis. The association between treatment periods and liver fibrosis on the SVR after 12 weeks of treatment rate was investigated. Results: The SVR rates in patients with chronic hepatitis with 8 weeks of treatment, chronic hepatitis with 12 weeks of treatment, cirrhosis with 8 weeks of treatment, and cirrhosis with 12 weeks of treatment were 98.9% (800/809), 100% (87/87), 100% (166/166), and 99.1% (211/213), respectively, and were was not different among these groups (P = 0.4). Conclusion: GLE/PIB therapy for chronic hepatitis C had high efficacy regardless of liver fibrosis status and treatment periods. Periods of GLE/PIB therapy could be chosen with available modalities, and high SVR rates could be achieved regardless of the decision.

RESUMO

INTRODUCTION: Pulsed lavage irrigation (PLI) is a procedure used to wash contaminated soft tissues and prevent infection in orthopedic surgery. We applicated PLI for surgical treatment of infective endocarditis( IE). SUBJECTS AND METHODS: From January 2017 to June 2021, 6 cases underwent surgical treatment IE using PLI. We investigated an efficacy of PLI. RESULTS: Infected valves were mitral valve in 4 cases, aortic valve in 1 case, and aortic prosthetic valve in 1 case. The performed procedures were mitral valve plasty in 4 cases, aortic valve replacement in 1 case, and 1 removal of vegetation on the aortic prosthetic valve. No recurrence of IE or no deterioration of the native valve or the prosthetic valve was observed in follow-up periods. CONCLUSION: PLI was useful for surgical treatment of IE because of no recurrence of IE or no deterioration of native mitral valves or the aortic prosthetic valve.

RESUMO

BACKGROUND: Oral immunotherapy (OIT) can ameliorate cow's milk allergy (CMA); however, the achievement of sustained unresponsiveness (SU) is challenging. Regarding the pathogenesis of CMA, recent studies have shown the importance of gut microbiota (Mb) and fecal water-soluble metabolites (WSMs), which prompted us to determine the change in clinical and gut environmental factors important for acquiring SU after OIT for CMA. METHODS: We conducted an ancillary cohort study of a multicenter randomized, parallel-group, delayed-start design study on 32 school-age children with IgE-mediated CMA who underwent OIT for 13 months. We defined SU as the ability to consume cow's milk exceeding the target dose in a double-blind placebo-controlled food challenge after OIT followed by a 2-week-avoidance. We longitudinally collected 175 fecal specimens and clustered the microbiome and metabolome data into 29 Mb- and 12 WSM-modules. RESULTS: During OIT, immunological factors improved in all participants. However, of the 32 participants, 4 withdrew because of adverse events, and only 7 were judged SU. Gut environmental factors shifted during OIT, but only in the beginning, and returned to the baseline at the end. Of these factors, milk- and casein-specific IgE and the Bifidobacterium-dominant module were associated with SU (milk- and casein-specific IgE; OR for 10 kUA/L increments, 0.67 and 0.66; 95%CI, 0.41-0.93 and 0.42-0.90; Bifidobacterium-dominant module; OR for 0.01 increments, 1.40; 95%CI, 1.10-2.03), and these associations were observed until the end of OIT. CONCLUSIONS: In this study, we identified the clinical and gut environmental factors associated with SU acquisition in CM-OIT.

RESUMO

BACKGROUND AND AIMS: Accurate risk stratification for hepatocellular carcinoma (HCC) after achieving a sustained viral response (SVR) is necessary for optimal surveillance. We aimed to develop and validate a machine learning (ML) model to predict the risk of HCC after achieving an SVR in individual patients. METHODS: In this multicenter cohort study, 1742 patients with chronic hepatitis C who achieved an SVR were enrolled. Five ML models were developed including DeepSurv, gradient boosting survival analysis, random survival forest (RSF), survival support vector machine, and a conventional Cox proportional hazard model. Model performance was evaluated using Harrel' c-index and was externally validated in an independent cohort (977 patients). RESULTS: During the mean observation period of 5.4 years, 122 patients developed HCC (83 in the derivation cohort and 39 in the external validation cohort). The RSF model showed the best discrimination ability using seven parameters at the achievement of an SVR with a c-index of 0.839 in the external validation cohort and a high discriminative ability when the patients were categorized into three risk groups (P <0.001). Furthermore, this RSF model enabled the generation of an individualized predictive curve for HCC occurrence for each patient with an app available online. CONCLUSIONS: We developed and externally validated an RSF model with good predictive performance for the risk of HCC after an SVR. The application of this novel model is available on the website. This model could provide the data to consider an effective surveillance method. Further studies are needed to make recommendations for surveillance policies tailored to the medical situation in each country. IMPACT AND IMPLICATIONS: A novel prediction model for HCC occurrence in patients after hepatitis C virus eradication was developed using machine learning algorithms. This model, using seven commonly measured parameters, has been shown to have a good predictive ability for HCC development and could provide a personalized surveillance system.

RESUMO

BACKGROUND: Platelet (PLT) transfusion was the most practical way to increase patients' PLT counts before invasive hepatic procedures such as radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). A novel drug that raises the PLT count by acting on the thrombopoietin receptor has recently become available. METHODS: Lusutrombopag 3 mg was administered daily for 7 days to patients who underwent RFA for liver tumors with low PLT counts (< 50,000 PLT µL- 1). We collected demographic data concerning the patients' liver function and PLT counts. RESULTS: Lusutrombopag was administered to 91 patients, with a median age of 71 years (range 51-86). Forty-two patients had hepatitis C, 12 had hepatitis B, 21 had alcoholic liver disease, 11 had nonalcoholic steatohepatitis, and five had other diseases. The median Child-Pugh score was 7 (range 5-11). Thirty-seven patients had stage I tumors, 41 had Stage II, 12 had stage III, and one had stage IV. PLT count was elevated from 4.4 × 104 ± 1.4 × 104 to 8.6 × 104 ± 2.5 × 104 PLT µL- 1. Lusutrombopag administration prevented PLT transfusions in 84/91 patients (92%). No patient had bleeding complications after RFA. One had portal thrombosis after lusutrombopag administration. Patients who achieved PLT counts of > 50,000 PLT µL- 1 had higher PLT counts before lusutrombopag administration. The degree of splenomegaly did not affect the rate of PLT count elevation. There was no specific adverse effect by administrating lusutrombopag for patients with PLT counts of around 50,000 µL- 1 but > 50,000 µL- 1. CONCLUSIONS: Lusutrombopag administration before RFA was effective and seemed to be relatively safe for hepatocellular carcinoma patients with low PLT counts. TRIAL REGISTRATION: This study was approved by Japanese Red Cross Medical Center Institutional Reseach Comittie (#862, 07/03/2016), and was registered in a publically accessible primary register (#UMIN000046629, registered date: 14/01/2022).

RESUMO

Background and Aim: Hepatocellular carcinoma (HCC) surveillance in low-risk patients (annual incidence <1.5%) is not recommended per the American Association for the Study of Liver Diseases guidelines. Because patients with chronic hepatitis C with non-advanced fibrosis who have achieved sustained virological response (SVR) have a low risk of HCC, HCC surveillance is not recommended for them. However, aging is a risk factor for HCC; threfore, the necessity for HCC surveillance in older patients with non-advanced fibrosis needs to be verified. Methods: This multicenter, prospective study enrolled 4993 patients with SVR (1998 patients with advanced fibrosis and 2995 patients with non-advanced fibrosis). The HCC incidence was examined with particular attention to age. Results: The 3-year incidence of HCC in patients with advanced and non-advanced fibrosis was 9.2% (95% CI: 7.8-10.9) and 2.9% (95% CI: 2.1-3.7), respectively. HCC incidence was significantly higher in patients with advanced fibrosis (P < 0.001). HCC incidence stratified by age and sex was investigated in patients with non-advanced fibrosis. The HCC incidence in the 18-49, 50s, 60s, 70s, and ≥80 age groups were 0.26, 1.3, 1.8, 1.7, and 2.9 per 100 person-years in men, and 0.00, 0.32, 0.58, 0.49, and 0.57 per 100 person-years in women, respectively. Conclusions: Male patients with non-advanced fibrosis aged ≥60 years have a higher risk of developing HCC and, thus, require HCC surveillance.

RESUMO

A 72-year-old female had persistent severe chest pain while climbing stairs. She was diagnosed as having acute coronary syndrome, and underwent an emergency coronary angiography (CAG). The right coronary artery (RCA) ostium was sub-totally occluded. Echocardiography revealed a 10 mm mobile mass at the right coronary cusp of the aortic valve. To avoid total obustruction on two drug eluting stents were placed at the RCA ostium so as to have the proximal end protrude into the right Valsalva sinus. Thus, her hemodynamic condition was stabilized. The tumor was surgically resected and the stents were easily removed. Pathologically, the tumor was papillary fibroelastoma. Postoperative aortic regurgitation was minimal echocardiography, and CAG showed normal RCA.

RESUMO

This study aimed to analyze the effects of photosynthetic photon flux density (PPFD) on fruit biomass radiation-use efficiency (FBRUE) of the dwarf tomato cultivar 'Micro-Tom' and to determine the suitable PPFD for enhancing the FBRUE under LED light at the reproductive growth stage. We performed four PPFD treatments under white LED light: 200, 300, 500, and 700 µmol m-2 s-1. The results demonstrated that a higher PPFD led to higher fresh and dry weights of the plants and lowered specific leaf areas. FBRUE and radiation-use efficiency (RUE) were the highest under 300 µmol m-2 s-1. FBRUE decreased by 37.7% because RUE decreased by 25% and the fraction of dry mass portioned to fruits decreased by 16.9% when PPFD increased from 300 to 700 µmol m-2 s-1. Higher PPFD (500 and 700 µmol m-2 s-1) led to lower RUE owing to lower light absorptance, photosynthetic quantum yield, and photosynthetic capacity of the leaves. High source strength and low fruit sink strength at the late reproductive growth stage led to a low fraction of dry mass portioned to fruits. In conclusion, 300 µmol m-2 s-1 PPFD is recommended for 'Micro-Tom' cultivation to improve the FBRUE at the reproductive growth stage.

RESUMO

BACKGROUND: Vonoprazan, a potassium-competitive acid blocker (VPZ), significantly reduces postoperative bleeding after gastric ESD; however, there is no consensus on the appropriate treatment duration. We conducted a randomized controlled study to demonstrate that the 3-week administration of VPZ is not inferior to the 8-week administration for ulcer healing. METHODS: This is a prospective, open-label multicenter randomized controlled trial. Patients aged 20-85 years undergoing gastric ESD were included in this study. The key exclusion criteria were patients with bleeding tendencies and those taking NSAIDs, steroids, PPIs, or VPZ medications. Eligible patients were randomly assigned to the VPZ 3w or 8w treatment group. The primary endpoint was the proportion of patients with complete closure of the post-ESD wound at 24 weeks after ESD. The key secondary endpoints included the proportion of patients with complete closure of the post-ESD wound at 8 weeks and the proportion of bleeding or perforation more than 3 weeks after ESD. RESULTS: From May 2018 to October 2020, 234 patients were included. The proportion of patients with complete ulcer closure was significantly lower in the 3w group than in the 8w group (70.8% vs. 90.6%) at 8 weeks post-treatment. The complete closure rates at 24 weeks in the 3w and 8w groups were 99.1% and 99.2%, respectively. The absolute difference in the closure rate at 24 weeks was - 0.059% [95% confidence interval (CI) -3.4% to 3.2], and the lower limit of the 95% CI exceeded -10%, the preset threshold. None of the patients developed delayed bleeding 3 weeks after ESD. CONCLUSION: This multicenter randomized study demonstrated that 3 weeks of treatment with VPZ is sufficient for ulcer healing.

RESUMO

Nucleos(t)ide analogs (NAs) cannot completely suppress the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B (CHB). This study aimed to identify the risk factors for HCC development in naïve CHB patients treated with current NA. Patients receiving NA (n = 905) were recruited retrospectively from the 17 hospitals of the Japanese Red Cross Liver Study Group. All treatment-naïve patients had been receiving current NA continuously for more than 1 year until the end of the follow-up. We analyzed the accuracy of predictive risk score using the area under receiver operating characteristic curve. The albumin-bilirubin (ALBI) score was significantly improved by NA therapy (-0.171 ± 0.396; p < 0.001 at Week 48). A total of 72 (8.0%) patients developed HCC over a median follow-up of 6.2 (1.03-15.7) years. An independent predictive factor of HCC development was older age, cirrhosis, lower platelet counts at baseline and ALBI score, and alpha-fetoprotein (AFP) at 1 year after NA therapy according to multivariate analysis. The accuracy was assessed using the PAGE-B, mPAGE-B, aMAP, APA-B, and REAL-B scores that included these factors. Discrimination was generally acceptable for these models. aMAP and REAL-B demonstrated high discrimination with 0.866/0.862 and 0.833/0.859 for 3- and 5-year prediction from the status of 1 year after NA therapy, respectively. Baseline age and platelet count, as well as ALBI and AFP one year after NA, were useful for stratifying carcinogenesis risk. The aMAP and REAL-B scores were validated with high accuracy in Japanese CHB patients.

RESUMO

In the present study, we found that EZH1 depletion in MYCN-amplified neuroblastoma cells resulted in significant cell death as well as xenograft inhibition. EZH1 depletion decreased the level of H3K27me1; the interaction and protein stabilization of MYCN and EZH1 appear to play roles in epigenetic transcriptional regulation. Transcriptome analysis of EZH1-depleted cells resulted in downregulation of the cell cycle progression-related pathway. In particular, Gene Set Enrichment Analysis revealed downregulation of reactome E2F-mediated regulation of DNA replication along with key genes of this process, TYMS, POLA2, and CCNA1. TYMS and POLA2 were transcriptionally activated by MYCN and EZH1-related epigenetic modification. Treatment with the EZH1/2 inhibitor UNC1999 also induced cell death, decreased H3K27 methylation, and reduced the levels of TYMS in neuroblastoma cells. Previous reports indicated neuroblastoma cells are resistant to 5-fluorouracil (5-FU) and TYMS (encoding thymidylate synthetase) has been considered the primary site of action for folate analogues. Intriguingly, UNC1999 treatment significantly sensitized MYCN-amplified neuroblastoma cells to 5-FU treatment, suggesting that EZH inhibition could be an effective strategy for development of a new epigenetic treatment for neuroblastoma.

RESUMO

Environmental stimuli modulate plant metabolite accumulation, facilitating adaptation to stressful conditions. In this study, the effects of blue and red light, photoperiod, CO2 concentration, and air temperature on the chlorogenic acid (CGA) and rutin contents of lettuce (Lactuca sativa L.) were evaluated. Under continuous blue light and a high CO2 concentration (1000 ppm), the CGA level increased. The increased expression of phenylalanine ammonia-lyase (PAL) and activity of its product were correlated with high expression of cinnamate 4-hydroxylase (C4H) and coumarate 3-hydroxylase (C3H). Furthermore, changes in PAL activity altered the CGA content in lettuce exposed to the three environmental factors, blue light, continuous lighting and high CO2 concentration. In addition, the expression levels of genes related to flavonoid biosynthesis increased in accordance with the promotion of CGA accumulation by the environmental factors. Under continuous blue light, 400 ppm CO2 promoted rutin accumulation to a greater degree compared to 1000 ppm CO2, by downregulating DFR expression. Low air temperature induced CGA accumulation in lettuce grown under continuous blue light and 1000 ppm CO2. Therefore, light quality, photoperiod, CO2 concentration, and air temperature exert synergistic effects on the CGA and rutin contents of lettuce by modulating activity in the corresponding biosynthesis pathways.

RESUMO

Ophiorrhiza pumila is a medicinal plant that grows in subtropical forests and produces camptothecin (CPT). To determine an optimal harvest time of O. pumila in a plant factory with artificial light (PFAL), we investigated the CPT distribution in each organ and at the developmental stage and estimated the annual CPT production. For this study, the O. pumila plants were grown in controlled environments (16 h light period, photosynthetic photon flux density of 100 µmol m-2 s-1 under white light-emitting diode lamps, air temperature of 28 °C, relative humidity of 80%, and CO2 concentration of 1000 µmol mol-1). First, the stem, root, and seed pod had higher CPT contents than the leaves, flower, and ovary. The optimal harvest time of O. pumila in a PFAL was 63 days after transplanting (DAT), because the CPT content in the whole organs was the highest at the seed-ripening stage. Second, based on these results, the estimated annual CPT production of O. pumila cultivated in a PFAL was 380 mg m-2 y-1 (63 DAT). This value was 4.3 times greater than the annual CPT production by Camptotheca acuminata in a greenhouse. We concluded that the CPT production by O. pumila in a PFAL throughout the year has many advantages, although the demand for electrical energy was high compared to that of Camptotheca acuminata in a greenhouse.

RESUMO

Background and Aim: To validate a composite predictive model for hepatocellular carcinoma (HCC) development in patients with advanced liver fibrosis associated with chronic hepatitis C virus (HCV) who have received direct-acting antiviral (DAA) therapy and achieved sustained virologic response (SVR). Methods: This study included 1258 patients with advanced liver fibrosis associated with HCV genotype 1, 2, or both. General evaluation score (GES), which is based on sex, age, fibrosis stage, albumin, and α-fetoprotein, was used as a composite predictive model. Results: There were 645 (51.3%) patients in the low-risk group, 228 (18.1%) in the intermediate-risk group, and 385 (30.6%) in the high-risk group based on GES categories. The 12-, 36-, and 60-month cumulative incidence of HCC was 0.7%, 5.3%, and 13.0%, respectively. Multivariable analysis with Cox proportional hazards models showed that male sex (hazard ratio [HR], 1.863; 95% confidence interval [CI], 1.204-2.883), F4 fibrosis stage (HR, 3.199; 95% CI, 1.696-6.036), and albumin (HR, 0.489; 95% CI, 0.288-0.828) are independently associated with HCC development. The incidence of HCC differed significantly by GES-based risk category (P < 0.001). Cox proportional hazards models showed that, with the low-risk group as the referent, the HR for HCC development was 1.875 (95% CI, 1.000-3.514) in the intermediate-risk group and 2.819 (95% CI, 1.716-4.630) in the high-risk group. GES had better predictive ability for HCC development than fibrosis-4 index according to time-dependent receiver operating characteristic analysis. Conclusion: GES is useful for predicting HCC development in patients with advanced liver fibrosis after SVR.

RESUMO

Improvements in the hepatocellular carcinoma (HCC) recurrence rate and survival have been frequently reported following virus eradication after hepatitis C virus (HCV)-related HCC cure. However, the efficacy of direct-acting antiviral (DAA) therapy in patients who included those with advanced HCC and decreased hepatic functional reserve is unknown. A comparative examination was retrospectively conducted of 141 patients with hepatitis C who started DAA therapy within 1 year after undergoing curative HCC treatment and showed a sustained viral response (SVR) and 327 patients who underwent curative treatment for HCV-related HCC and did not subsequently receive antiviral therapy. Whether DAA therapy was given was identified as an independent factor related to both HCC recurrence and survival. Both the recurrence and survival rates improved significantly with DAA therapy in Child-Pugh (CP)-A, whereas no difference in the recurrence rate was seen with DAA therapy in CP-B. However, the survival rate was significantly higher in the DAA group in this class. Similarly, dividing the patients by the Milan criteria showed significant improvements in the recurrence rate and survival with DAA therapy in patients within the Milan criteria. Patients with HCC beyond the Milan criteria showed no difference in recurrence rates, but the DAA group tended to have higher survival rates. Thus, DAA after curative therapy for HCC can be expected to improve survival in patients with advanced HCC or decreased hepatic functional reserve. HCV should be aggressively eradicated in all patients eligible for curative treatment of HCC.

RESUMO

Post-stroke antiplatelet therapy has been proved to reduce the risk of recurrent stroke; however, it may also increase the incidence of intracranial hemorrhage that could offset any benefits. Therefore, the balance between the benefits and risks of antiplatelet drugs is a critical issue to consider. In the present study, we have compared the effects of post-stroke administration of antiplatelet agents on functional outcomes in the stroke-prone spontaneously hypertensive rat (SHRSP), an established animal model that mimics human lacunar stroke and cerebral small vessel disease. We confirmed that a potent phosphodiesterase 3 (PDE3) inhibitor, K-134, significantly improved post-stroke survival rate and survival time, attenuated stroke-induced neurological deficits, and decreased the incidence of cerebral lesion caused by intracerebral hemorrhage and softening. Similarly, cilostazol showed beneficial effects, though to a lower extent with respect to the survival outcome and neurological symptoms. On the other hand, a P2Y12 inhibitor, clopidogrel significantly improved survival outcomes at the higher dose but caused massive bleeding in the brain at both low and high doses. In contrast, no hemorrhagic lesion was observed in K-134-treated SHRSPs despite its antiplatelet activity. Our findings indicate that K-134 may have a superior post-stroke therapeutic outcome in comparison to other antiplatelet drugs.

BACKGROUND AND AIM: The pathogenic process underlying the development of hepatocellular carcinoma (HCC) is not yet clear in patients with hepatitis C virus (HCV) who have received direct-acting antiviral (DAA) therapy and achieved sustained virological response (SVR). This study validated a composite predictive model for HCC in these patients. METHODS: This study included 3058 patients in whom HCV was eradicated with DAA therapy. After DAAs recommendation for surveillance (ADRES) score, which is based on sex, FIB-4 index, and α-fetoprotein, was used as a composite predictive model for HCC development. RESULTS: The 1-, 3-, and 5-year cumulative incidence rates of HCC were 0.9, 4.5, and 15.2%, respectively. Multivariate analysis with Cox proportional hazards models showed that male sex (hazard ratio [HR], 2.646; 95% confidence interval [CI], 1.790-3.911), FIB-4 index >3.25 (HR, 2.891; 95% CI, 1.947-4.293), and α-fetoprotein >5 ng/mL (HR, 2.835; 95% CI, 1.914-4.200) are independently associated with HCC development. The incidence of HCC differed significantly by ADRES score (P < 0.001). Cox proportional hazards models showed that compared to the ADRES score 0 group, the HR for HCC development was 2.947 (95% CI, 1.367-6.354) in the ADRES score 1 group, 9.171 (95% CI, 4.339-19.380) in the ADRES score 2 group, and 20.630 (95% CI, 8.641-49.230) in the ADRES score 3 group. ADRES score had superior predictive power for HCC development compared with the FIB-4 index and α-fetoprotein according to time-dependent receiver operating characteristic analysis. CONCLUSION: The ADRES score is useful for predicting HCC development after SVR.

RESUMO

The identification of patients with advanced fibrosis who do not need any further hepatocellular carcinoma (HCC) surveillance after the eradication of hepatitis C is pivotal. In this study, we developed a simple serum-based risk model that could identify patients with low-risk HCC. This was a nationwide multicenter study involving 16 Hospitals in Japan. Patients with advanced fibrosis (1,325 in a derivation cohort and 508 in a validation cohort) who achieved sustained virological responses at 24 weeks after treatment (SVR24) were enrolled. The HCC risk model at any point after SVR24 and its change were evaluated, and subsequent HCC development was analyzed. Based on the multivariable analysis, patients fulfilling all of the factors (GAF4 criteria: gamma-glutamyl transferase < 28 IU/L, alpha-fetoprotein < 4.0 ng/mL, and Fibrosis-4 Index < 4.28) were classified as low-risk and others were classified as high-risk. When patients were stratified at the SVR24, and 1 year, and 2 years after SVR24, subsequent HCC development was significantly lower in low-risk patients (0.5-1.1 per 100 person-years in the derivation cohort and 0.9-1.1 per 100 person-years in the validation cohort) than in high-risk patients at each point. HCC risk from 1 year after SVR24 decreased in patients whose risk improved from high-risk to low-risk (HCC incidence: 0.6 per 100 person-years [hazard ratio (HR) = 0.163 in the derivation cohort] and 1.3 per 100 person-years [HR = 0.239 in the validation cohort]) than in those with sustained high risk. Conclusion: The HCC risk model based on simple serum markers at any point after SVR and its change can identify patients with advanced fibrosis who are at low HCC risk, and these patients may be able to reduce HCC surveillance.

RESUMO

A 78-year-old woman presenting with severe acute liver failure was admitted to our hospital. On screening for the etiology of acute liver failure, it was diagnosed as being due to idiopathic hypereosinophilic syndrome (eosinophil count reported as 4766/µL; 33.8% of the white blood cells). Her medical history included marked eosinophilia, as observed six months prior to this admission. Corticosteroid therapy was initiated. During the clinical course, duodenal perforation occurred but was managed promptly by appropriate surgery. A liver biopsy, following the initiation of corticosteroid therapy, revealed degenerating hepatic cells with mild eosinophilic infiltration. With corticosteroid therapy, the liver function improved.

RESUMO

INTRODUCTION AND IMPORTANCE: While the number of SAVR cases has been increasing for patients below their sixties due to the improvement of bioprosthetic valves, some early structural valve deterioration (SVD) in Trifecta valves has been reported. CASE PRESENTATION: We present a case of a female who presented with sudden shortness of breath. Ultrasonography diagnosed SVD. We performed redo aortic valve replacement due to SVD in Trifecta valve. With our surgical technique we could remove the bioprosthetic valve easily. CLINICAL DISCUSSION: We could easily remove the mounted prosthetic valve along with the titanium band. These cases may emerge with acute heart failure due to sudden massive aortic regurgitation, not like the gradual progression of stenosis due to calcification. CONCLUSION: The postoperative course in Trifecta recipients must be followed carefully.
