sirolimus and Hepatitis-B

Middle East Respiratory Syndrome (MERS) is a novel respiratory illness firstly reported in Saudi Arabia in 2012. It is caused by a new corona virus, called MERS corona virus (MERS-CoV). Most people who have MERS-CoV infection developed severe acute respiratory illness.. This work is done to determine the clinical characteristics and the outcome of intensive care unit (ICU) admitted patients with confirmed MERS-CoV infection.. This study included 32 laboratory confirmed MERS corona virus infected patients who were admitted into ICU. It included 20 (62.50%) males and 12 (37.50%) females. The mean age was 43.99 ± 13.03 years. Diagnosis was done by real-time reverse transcription polymerase chain reaction (rRT-PCR) test for corona virus on throat swab, sputum, tracheal aspirate, or bronchoalveolar lavage specimens. Clinical characteristics, co-morbidities and outcome were reported for all subjects.. Most MERS corona patients present with fever, cough, dyspnea, sore throat, runny nose and sputum. The presence of abdominal symptoms may indicate bad prognosis. Prolonged duration of symptoms before patients' hospitalization, prolonged duration of mechanical ventilation and hospital stay, bilateral radiological pulmonary infiltrates, and hypoxemic respiratory failure were found to be strong predictors of mortality in such patients. Also, old age, current smoking, smoking severity, presence of associated co-morbidities like obesity, diabetes mellitus, chronic heart diseases, COPD, malignancy, renal failure, renal transplantation and liver cirrhosis are associated with a poor outcome of ICU admitted MERS corona virus infected patients.. Plasma HO-1, ferritin, p21, and NQO1 were all elevated at baseline in CKD participants. Plasma HO-1 and urine NQO1 levels each inversely correlated with eGFR (. SnPP can be safely administered and, after its injection, the resulting changes in plasma HO-1, NQO1, ferritin, and p21 concentrations can provide information as to antioxidant gene responsiveness/reserves in subjects with and without kidney disease.. A Study with RBT-1, in Healthy Volunteers and Subjects with Stage 3-4 Chronic Kidney Disease, NCT0363002 and NCT03893799.. HFNC did not significantly modify work of breathing in healthy subjects. However, a significant reduction in the minute volume was achieved, capillary [Formula: see text] remaining constant, which suggests a reduction in dead-space ventilation with flows > 20 L/min. (ClinicalTrials.gov registration NCT02495675).. 3 组患者手术时间、术中显性失血量及术后 1 周血红蛋白下降量比较差异均无统计学意义（. 对于肥胖和超重的膝关节单间室骨关节炎患者，采用 UKA 术后可获满意短中期疗效，远期疗效尚需进一步随访观察。.. Decreased muscle strength was identified at both time points in patients with hEDS/HSD. The evolution of most muscle strength parameters over time did not significantly differ between groups. Future studies should focus on the effectiveness of different types of muscle training strategies in hEDS/HSD patients.. These findings support previous adverse findings of e-cigarette exposure on neurodevelopment in a mouse model and provide substantial evidence of persistent adverse behavioral and neuroimmunological consequences to adult offspring following maternal e-cigarette exposure during pregnancy. https://doi.org/10.1289/EHP6067.. This RCT directly compares a neoadjuvant chemotherapy regimen with a standard CROSS regimen in terms of overall survival for patients with locally advanced ESCC. The results of this RCT will provide an answer for the controversy regarding the survival benefits between the two treatment strategies.. NCT04138212, date of registration: October 24, 2019.. Results of current investigation indicated that milk type and post fermentation cooling patterns had a pronounced effect on antioxidant characteristics, fatty acid profile, lipid oxidation and textural characteristics of yoghurt. Buffalo milk based yoghurt had more fat, protein, higher antioxidant capacity and vitamin content. Antioxidant and sensory characteristics of T. If milk is exposed to excessive amounts of light, Vitamins B. The two concentration of ZnO nanoparticles in the ambient air produced two different outcomes. The lower concentration resulted in significant increases in Zn content of the liver while the higher concentration significantly increased Zn in the lungs (p < 0.05). Additionally, at the lower concentration, Zn content was found to be lower in brain tissue (p < 0.05). Using TEM/EDX we detected ZnO nanoparticles inside the cells in the lungs, kidney and liver. Inhaling ZnO NP at the higher concentration increased the levels of mRNA of the following genes in the lungs: Mt2 (2.56 fold), Slc30a1 (1.52 fold) and Slc30a5 (2.34 fold). At the lower ZnO nanoparticle concentration, only Slc30a7 mRNA levels in the lungs were up (1.74 fold). Thus the two air concentrations of ZnO nanoparticles produced distinct effects on the expression of the Zn-homeostasis related genes.. Until adverse health effects of ZnO nanoparticles deposited in organs such as lungs are further investigated and/or ruled out, the exposure to ZnO nanoparticles in aerosols should be avoided or minimised.

Hepatitis B reactivation can occur with cytotoxic chemotherapy in patients with hepatitis B and cancer. Reactivation can occur in a patient with chronic hepatitis, an inactive carrier, or one with resolved hepatitis. Clinical presentation may range from subclinical elevation of liver enzymes to fatal fulminant hepatic failure. Mammalian target of rapamycin inhibitors, which include everolimus, are a new generation of targeted agents that are currently approved for many cancers (since March 2009) including advanced hormone receptor positive, human epidermal growth factor receptor 2-negative breast cancer, in conjunction with exemestane (as of July 2012). We are therefore still learning the various adverse events that occur with this new class of agents. Here, we present an unfortunate case of fatal hepatitis B reactivation in a woman with metastatic breast cancer treated with everolimus and exemestane. We have detailed the controversies around hepatitis B screening prior to immunosuppressive therapy. Clinicians and patients should be aware of this rare but fatal complication prior to everolimus use, and a detailed history, screening for hepatitis B and prophylactic antiviral treatment should be considered.

Deregulation of mammalian target of rapamycin (mTOR) signalling is common in human hepatocellular carcinoma (HCC).. To determine the maximum tolerated dose (MTD) of the oral mTOR inhibitor everolimus in advanced HCC patients.. Patients with locally advanced or metastatic HCC (Child-Pugh class A or B) were enrolled in an open-label phase 1 study and randomly assigned to daily (2.5-10 mg) or weekly (20-70 mg) everolimus in a standard 3 + 3 dose-escalation design. MTD was based on the rate of dose-limiting toxicities (DLTs). Secondary endpoints included safety, pharmacokinetics and tumour response. In a post hoc analysis, serum hepatitis B virus (HBV) DNA levels were quantified.. Thirty-nine patients were enrolled. DLTs occurred in five of 21 patients in the daily and two of 19 patients in the weekly cohort. Daily and weekly MTDs were 7.5 mg and 70 mg respectively. Grade 3/4 adverse events with a ≥10% incidence were thrombocytopenia, hypophosphataemia and alanine transaminase (ALT) elevation. In four hepatitis B surface antigen (HBsAg)-seropositive patients, grade 3/4 ALT elevations were accompanied by significant (>1 log) increases in serum HBV levels. The incidence of hepatitis flare (defined as ALT increase >100 IU/mL from baseline) in HBsAg-seropositive patients with and without detectable serum HBV DNA before treatment was 46.2% and 7.1% respectively (P < 0.01, Fisher exact test). Disease control rates in the daily and weekly cohorts were 71.4% and 44.4% respectively.. The recommended everolimus dosing schedule for future hepatocellular carcinoma studies is 7.5 mg daily. Prophylactic anti-viral therapy should be mandatory for HBsAg-seropositive patients (ClinicalTrials.gov NCT00390195).

Some experimental trials have demonstrated that rapamycin (RAPA) is able to inhibit HIV-1 progression in three different ways: (1) reducing CCR5-gene transcription, (2) blocking interleukin-2 intracellular secondary messenger (mammalian target of rapamycin), and (3) up-regulating the beta-chemokine macrophage inflammatory protein (MIP; MIP-1alpha and MIP-1beta). We present the preliminary results of a prospective nonrandomized trial concerning the first HIV patient series receiving RAPA monotherapy after liver transplantation (LT).. Since June 2003, 14 HIV patients have received cadaveric donor LT due to end-stage liver disease (ESLD) associated or not associated with hepatocellular carcinoma, scored by the model for ESLD system. Patients were assessed using the following criteria for HIV characterization: CD4 T-cell count more than 100/mL and HIV-RNA levels less than 50 copies/mL. Primary immunosuppression was based on calcineurin inhibitors (CI), whereas switch to RAPA monotherapy occurred in cases of CI complications or Kaposi's sarcoma.. Mean overall post-LT follow-up was 14.8 months (range: 0.5-52.6). Six of 14 patients were administered RAPA monotherapy. Mean preswitch period from CI to RAPA was 67 days (range: 10-225 days). Mean postswitch follow-up was 11.9 months (range: 2-31 months). All patients were affected by ESLD, which was associated with hepatocellular carcinoma in seven patients. ESLD occurred due to hepatitis C virus (HCV)-related hepatopathy for nine patients, hepatitis B virus-related hepatopathy for one patient, and hepatitis B virus-HCV hepatopathy for four patients. Significantly better control of HIV and HCV replication was found among patients taking RAPA monotherapy (P=0.0001 and 0.03, respectively).. After in vitro and in vivo experimental evidence of RAPA antiviral proprieties, to our knowledge, this is the first clinical report of several significant benefits in long-term immunosuppression maintenance and HIV-1 control among HIV positive patients who underwent LT.

Hepatitis B virus (HBV) infection is a disease with high incidence and lack of effective treatment. In this study, we further explored the mechanism of resveratrol (RVT) in the inhibition of HBV replication. The effects of RVT on HBV replication were verified using in vitro and in vivo experiments.. HepG2 and HepG2.2.15 cell lines were cultured in vitro, and different concentrations of RVT were used to determine its effect on the proliferation of the two cell lines. Autophagy agonists and inhibitors were given, and whether RVT exerts its effect on the proliferation of HepG2 and HepG2.2.15 cells through autophagy was determined. Reverse transcription-quantitative polymerase chain reaction and Western blot were used to detect changes in autophagy-related factors LC3-II, LC3-I, Beclin 1, and p62. Through transfection of pmiR-155, shmiR-155, and the corresponding control group, the relevant mechanism of RVT in inhibiting the proliferation of HepG2 and HepG2.2.15 cells was analyzed. RVT inhibited the toxicity for HepG2.2.15 cells and reduced HBV replication in vitro (p < 0.05). This effect of RVT was enhanced by rapamycin (RAPA; autophagy activator; p < 0.05) but was partially reversed by 3-MA (autophagy inhibitor; p < 0.05). In addition, our results showed that miR-155 expression was higher in HepG2.2.15 cells than in HepG cells (p < 0.05). miR-155 expression in the RVT treatment group was significantly reduced (p < 0.05). We designed an miR-155 overexpression plasmid, low miR-155 expression plasmid, and the corresponding negative control for transfection and found that transfection of pmiR-155 can partially reverse the effect of RVT (p < 0.05), while transfection with shmiR-155 can enhance the effect of RVT (p < 0.05).. RVT inhibits miR-155, activates autophagy, inhibits the toxicity for HepG2.2.15 cells, and reduces HBV replication, providing a new research direction for the treatment of HBV infection.

A 34-year-old woman experiencing shortness of breath was referred to our hospital. The patient was diagnosed with sporadic lymphangioleiomyomatosis based on the observation of bilateral diffuse multiple thin-walled cysts on computed tomography of the chest, chylous effusion, elevated serum vascular endothelial growth factor-D levels and transbronchial biopsy findings. This patient was a hepatitis B virus (HBV) carrier. Treatment with 1 mg daily of sirolimus was started after HBV DNA was brought below the cut-off level using entecavir. Sirolimus was effective, as the chylous effusion resolved completely and the dyspnea improved. The sirolimus dosage was increased to 2 mg daily without causing HBV reactivation.

The replication of hepatitis B virus (HBV) may be modulated by a variety of cell signaling pathways, including the phosphatidylinositol 3‑kinase (PI3K)‑RAC‑α serine/threonine‑protein kinase (AKT)‑serine/threonine‑protein kinase mTOR (mTOR) pathway. The aim of the present study was to determine the regulatory effects of this pathway on the infection and replication of HBV. The results indicated that the HBV entry process may activate the AKT pathway, as demonstrated by AKT phosphorylation in HBV natural infection. However, inhibition of AKT phosphorylation by short‑term treatment with AKT inhibitors was unable to block HBV entry, which suggested that AKT activation induced by HBV infection is not essential for viral entry process. Prolonged treatment with PI3K‑AKT‑mTOR pathway inhibitors markedly promoted HBV replication in HBV replicating and natural infection models. The PI3K‑AKT‑mTOR pathway was therefore identified to be a negative regulator of HBV replication. These inhibitors enhanced the replication and transcription of HBV in an HBx‑dependent way. The results additionally indicated that a PI3K inhibitor, Ly294002, inhibited the secretion of the small surface antigen of HBV in a PI3K‑AKT‑independent manner. The inhibitor Ly294002 may be used as a tool for the drug development of surface antigen secretion inhibitors.

Current anti-hepatitis B virus (HBV) agents have limited effect in curing HBV infection, and thus novel anti-HBV agents with different modes of action are in demand. In this study, we applied AlphaScreen assay to high-throughput screening of small molecules inhibiting the interaction between HBV large surface antigen (LHBs) and the HBV entry receptor, sodium taurocholate cotransporting polypeptide (NTCP). From the chemical screening, we identified that rapamycin, an immunosuppressant, strongly inhibited the LHBs-NTCP interaction. Rapamycin inhibited hepatocyte infection with HBV without significant cytotoxicity. This activity was due to impaired attachment of the LHBs preS1 domain to cell surface. Pretreatment of target cells with rapamycin remarkably reduced their susceptibility to preS1 attachment, while rapamycin pretreatment to preS1 did not affect its attachment activity, suggesting that rapamycin targets the host side. In support of this, a surface plasmon resonance analysis showed a direct interaction of rapamycin with NTCP. Consistently, rapamycin also prevented hepatitis D virus infection, whose entry into cells is also mediated by NTCP. We also identified two rapamycin derivatives, everolimus and temsirolimus, which possessed higher anti-HBV potencies than rapamycin. Thus, this is the first report for application of AlphaScreen technology that monitors a viral envelope-receptor interaction to identify viral entry inhibitors.

Hepatitis B virus (HBV) infection plays a crucial role and is a major cause of hepatocellular carcinoma (HCC) in China. microRNAs (miRNAs) have emerged as key players in hepatic steatosis and carcinogenesis. We found that down-regulation of miR-384 expression was a common event in HCC, especially HBV-related HCC. However, the possible function of miR-384 in HBV-related HCC remains unclear. The oncogene pleiotrophin (PTN) was a target of miR-384. HBx inhibited miR-384, increasing PTN expression. The PTN receptor N-syndecan was highly expressed in HCC. PTN induced by HBx acted as a growth factor via N-syndecan on hepatocytes and further promoted cell proliferation, metastasis and lipogenesis. PTN up-regulated sterol regulatory element-binding protein 1c (SREBP-1c) through the N-syndecan/PI3K/Akt/mTORC1 pathway and the expression of lipogenic genes, including fatty acid synthesis (FAS). PTN-mediated de novo lipid synthesis played an important role in HCC proliferation and metastasis. PI3K/AKT and an mTORC1 inhibitor diminished PTN-induced proliferation, metastasis and lipogenesis. Taken together, these data strongly suggest that the dysregulation of miR-384 could play a crucial role in HBV related to HCC, and the target gene of miR-384, PTN, represents a new potential therapeutic target for the prevention of hepatic steatosis and further progression to HCC after chronic HBV infection.

The risks for transplant outcomes associated with baseline viral serostatus in kidney transplant recipients (KTR) on sirolimus have not been widely studied.. We performed a cohort-study of 61 590 adult KTR in 2000 to 2013. We used Cox regression models to determine the adjusted hazard ratio (aHR) of patient death, death-censored graft loss and posttransplant malignancy associated with the baseline serostatus (+ or -: hepatitis B core [HBc], hepatitis C virus [HCV], Epstein-Barr virus [EBV], or cytomegalovirus [CMV]) in KTR on sirolimus (SRL) + mycophenolate (MPA) or SRL + tacrolimus (Tac), relative to the control-regimen: Tac + MPA.. Compared with Tac + MPA, SRL + MPA, and SRL + Tac were associated with higher risks of 5-year mortality (aHR, 1.41; 95% CI, 1.23-1.60 and aHR, 1.59; 95% CI, 1.38-1.83, respectively) and death-censored graft loss (aHR, 1.41; 95% CI, 1.24-1.60 and aHR, 1.38; 95% CI, 1.21-1.57, respectively). In KTR with negative pretransplant EBV, CMV, HBc, or HCV serostatus, SRL + MPA not SRL + Tac was associated with a lower risk of posttransplant malignancy compared with control (aHR, 0.27; 95% CI, 0.10-0.72; aHR, 0.61; 95% CI, 0.43-0.88; aHR, 0.79; 95% CI, 0.64-0.97; and aHR, 0.80; 95% CI, 0.65-0.98, respectively, for SRL + MPA and aHR, 0.98: 95% CI, 0.52-1.80; aHR, 0.69; 95% CI, 0.46-1.06; aHR, 0.83; 95% CI, 0.66-1.06 and aHR, 0.85; 95% CI, 0.67-1.07, respectively, for SRL + Tac). In KTR with positive serostatus to any of the above viruses, SRL + MPA or SRL + Tac was not associated with a different malignancy risk compared with control.. Compared with Tac + MPA, SRL regimens were associated with higher risks for patient death and graft loss, although SRL + MPA was associated with a lower risk for posttransplant malignancy in kidney allograft recipients with negative pretransplant HBc, HCV, EBV, or CMV serology.

Immunosuppressive agents used postoperatively after liver transplantation (LT) for hepatocellular carcinoma (HCC) favor recurrence and metastasis. Therefore, new effective immunosuppressants are needed. This retrospective study assessed combined sirolimus and metformin on survival of HCC patients after LT. In 2001-2013, 133 HCC patients with LT were divided into four groups: sirolimus and metformin combination (Sir+Met), sirolimus monotherapy (Sir), other immunosuppressants in diabetes mellitus (DM) patients without metformin (No Sir with DM), and other immunosuppressants in patients without DM (No Sir without DM). Kaplan-Meier and Log-rank tests were used to assess survival. Cell proliferation and tumor xenograft assays were performed to disclose the mechanisms underlying the sirolimus and metformin effects. The Sir+Met group showed significantly prolonged survival compared to the other groups. The most significant cytotoxicity was seen in the Sir+Met group, with significantly decreased levels of phosphorylated PI3K, AKT, AMPK, mTOR, 4EBP1 and S6K, compared with the other groups. In agreement, Sir+Met had the highest suppressive effect on tumor growth among all groups (P<0.01). In summary, Sir+Met treatment significantly prolonged survival, likely by suppressing cell proliferation. Therefore, this combination could represent a potential routine-regimen for patients post LT.

Glycine N-methyltransferase (GNMT) is a tumor suppressor for hepatocellular carcinoma (HCC). High rates of Gnmt knockout mice developed HCC. Epigenetic alteration and dysregulation of several pathways including wingless-type MMTV integration site (Wnt), mitogen-activated protein kinase (MAPK) and Janus kinase and signal transducer and activator of transcription (JAK-STAT) are associated with HCC development in Gnmt knockout mice. We hypothesized that GNMT may regulate signal transduction through interacting with other proteins directly. In this report, we identified a mammalian target of rapamycin (mTOR) inhibitor (DEP domain containing MTOR-interacting protein [DEPDC6/DEPTOR]) as a GNMT-binding protein by using yeast two-hybrid screening. Fluorescence resonance energy transfer assay demonstrated that the C-terminal half of GNMT interact with the PSD-95/Dlg1/ZO-1 (PDZ) domain of DEPDC6/DEPTOR. Immunohistochemical staining showed that 27.5% (14/51) of HCC patients had higher expression levels of DEPDC6/DEPTOR in the tumorous tissues than in tumor-adjacent tissues, especially among HCC patients with hepatitis B viral infection (odds ratio 10.3, 95% confidence interval [CI] 1.05-11.3) or patients with poor prognosis (death hazard ratio 4.51, 95% CI 1.60-12.7). In terms of molecular mechanism, knockdown of DEPDC6/DEPTOR expression in HuH-7 cells caused S6K and 4E-BP activation, but suppressed Akt. Overexpression of DEPDC6/DEPTOR activated Akt and increased survival of HCC cells. Overexpression of GNMT caused activation of mTOR/raptor downstream signaling and delayed G2/M cell cycle progression, which altogether resulted in cellular senescence. Furthermore, GNMT reduced proliferation of HuH-7 cells and sensitized them to rapamycin treatment both in vitro and in vivo. In conclusion, GNMT regulates HCC growth in part through interacting with DEPDC6/DEPTOR and modulating mTOR/raptor signaling pathway. Both GNMT and DEPDC6/DEPTOR are potential targets for developing therapeutics for HCC.

Tumor recurrence represents the main limitation of liver transplantation in patients with hepatocellular carcinoma (HCC) and can be favored by exposure to calcineurin inhibitors.. We investigated the effect of an immunosuppressant schedule that minimizes the exposure to calcineurin inhibitors on patients transplanted for HCC to ascertain whether this can reduce the tumor recurrence rate. For this purpose, we conducted a matched-cohort study: 31 patients with HCC transplanted between 2004 and 2007 who received sirolimus as part of their immunosuppression (group A) were compared with a control group of 31 patients (group B) transplanted in the same period who had the same prognostic factors but were given standard immunosuppression based on tacrolimus.. Three-year recurrence-free survival was 86% in group A and 56% in group B (P=0.04). Although the prevalence of microvascular invasion G3-G4 grading and alpha-fetoprotein more than 200 ng/mL was identical in the two groups, exposure to tacrolimus was significantly higher in patients of group B (median, 8.54; range, 5.5-13.5) in comparison with those of group A (median, 4.6; range, 1.8-9.1) (P=0.0001).. By using sirolimus, exposure to calcineurin inhibitors can be minimized, reducing the risk of HCC recurrence.

We retrospectively analyzed the impact of sirolimus addition (SRL) with a 25% dosing reduction in calcineurin inhibitors on liver function among patients with or without hepatitis B virus (HBV) or hepatitis C virus (HCV) infection.. Forty-eight renal transplant recipients (HBsAg-positive, n = 5; anti-HCV-positive, n = 7) with allograft dysfunction (serum creatinine: mean 2.7, median 2.0 mg/dL) and normal liver function were enrolled. The duration of the SRL add-on therapy was 8.0 +/- 3.6 months. SRL trough levels were maintained within 6.5 +/- 3.7 ng/mL. The trough levels of tacrolimus and the 2-hour cyclosporine postdose levels were tapered to 4.6 +/- 1.9 ng/mL (24.6% reduction) and 650 +/- 170 ng/mL (24.3% reduction), respectively. SRL-related hepatitis was defined as a rise in liver transferase or alkaline phosphatase or bilirubin over twice the upper limit of normal. Thirty-six HBsAg-negative and anti-HCV-negative patients served as the controls.. Hepatotoxicity developed in 6 (12.5%) of the 48 patients and in 3 (8.3%) of 36 control subjects. One (20.0%) of five HBsAg-positive patients (P = .959) and two (28.6%) of seven anti-HCV-positive patients (P = .496) developed hepatotoxicity, respectively. Three (25.0%) of the 12 HBsAg-positive or anti-HCV-positive patients developed hepatotoxicity (P = .420).. Patients with seropositivity of HBsAg or anti-HCV had an insignificantly higher percentage of hepatitis. Use of SRL in the HBV/HCV patients is not contraindicated, but needs monitoring for HBV/HCV activation.

The phosphatidylinositol 3-kinase (PI3K)-protein kinase B (Akt) signaling pathway is one of the major oncogenic pathways and is activated in many types of human cancers, including hepatocellular carcinoma. It can also be activated by the hepatitis C virus (HCV) nonstructural 5A (NS5A) protein. In the present study, we set out to determine the regulatory effects of this pathway on the replication of hepatitis B virus (HBV). Our results demonstrate that the expression of a constitutively active Akt1 profoundly inhibited HBV RNA transcription and consequently reduced HBV DNA replication in HepG2 cells. This suppression of HBV gene transcription was apparently mediated by the activation of mTOR, as it was abolished by the mTOR inhibitor rapamycin. Moreover, treatment of HBV-expressing HepG2.2.15 cells with inhibitors of PI3K, Akt, and mTOR increased the transcription of 3.5-kb and 2.4-kb viral RNA as well as the replication of HBV DNA. This observation implies that the basal level activation of this pathway in HepG2 cells regulated HBV replication. Consistent with previous reports showing that the HCV NS5A protein could bind to the p85 subunit of PI3K and activate the PI3K-Akt signal transduction pathway, our results showed that expression of this protein could inhibit HBV RNA transcription and reduce HBV DNA replication in HepG2 cells. Taken together, our results suggest that the activation of the PI3K-Akt pathway during liver oncogenesis may be at least partially responsible for the elimination of HBV replication from tumor cells and may also provide an explanation for the observed suppression of HBV replication by HCV coinfection.

This 44-year-old woman developed multifocal hepatocellular carcinoma (HCC) within hepatitis B-induced liver cirrhosis. At the time of listing for transplantation the HCC had progressed beyond the Milan criteria. Due to her young age, high grade of histological differentiation according to biopsy, and lack of therapeutic alternatives, she was listed for transplantation. She received an organ from the Eurotransplant marginal liver list. Immunosuppression was reduced to tacrolimus monotherapy within 4 months. Five months after transplantation bilateral bulky ovarian metastases were seen on computed tomography (CT) scan. A bilateral salphingo-oophorectomy was performed and immunosuppression switched to sirolimus monotherapy. Fourteen months after this procedure and 19 months after transplantation, the patient is asymptomatic with stable liver function. She is free of recurrence as judged by CT scan, bone scan, and alpha-fetoprotein. In conclusion, radical surgical treatment and immunosuppression using sirolimus may achieve tumor-free survival in selected patients with advanced or recurrent HCC.
