RESUMO

PURPOSE: To assess prospectively long-term results of doxorubicin-loaded HepaSphere 30-60 µm in consecutive patients with hepatocellular carcinoma (HCC) not amenable to curative treatments. PATIENTS AND METHODS: Single-center study from June 2011 to December 2015 in 151 patients treated with 75 mg of doxorubicin per HepaSphere vial. Baseline: Barcelona Clinic Liver Cancer BCLC A/B was 49.3%/50.7%, and median diameter 6.1 cm (mean 6.7 ± 2.0). Liver function, local response (mRECIST), liver time to progression (LTTP), progression-free survival (PFS), overall survival (OS) and adverse events (AEs) were recorded. RESULTS: Final analysis included 142 patients with median follow-up of 46.8 months (range 4-72) without grade 4/5 AEs, and 30-day mortality was 0%. Mean number of scheduled treatments was 2.6 (range 1-3) and on demand 3 (range 1-8). Complete response for single tumor ≤ 5 cm was 75.0% and 66.7% for Child A and Child B, while for > 5 cm was 28.6% and 11.8%, respectively. OS was 31.0 months (mean 33.3 ± 15.2; range 8-69), notably for BCLC A 41 months (mean 41.1 ± 15.3; range 13-69) and for BCLC B 26.0 (mean 26.0 ± 10.5; range 8-51). OS at 1, 3 and 5 years: 95.8%, 75.7% and 21.4% for BCLC A, and 94.4%, 36.1% and 2.7% for BCLC B. Median LTTP for BCLC A was 11 months (mean 11.9 ± 4.7; range 3-24) and 7.5 for BCLC B (mean 7.9 ± 2.9). Local response was significant for OS and LTTP (p < 0.0001), while size and lesion number affected LPFS and OS (p < 0.001). CONCLUSIONS: HepaSphere 30-60 µm loaded with doxorubicin provides a safe and effective treatment option for patients with HCC.

RESUMO

Infections due to drug-resistant (DR) bacteria are increasingly recognized as an emerging problem worldwide. Asymptomatically colonized patients may contribute to the reservoir in the hospital setting, causing both horizontal transmission and endogenous infections. We aimed to evaluate the prevalence of intestinal colonization with DR bacteria on subsequent clinical infection development and prognosis in patients with decompensated cirrhosis. One hundred seven patients without infection at baseline were screened and prospectively followed-up for 3 months. Among the patients screened, DR bacteria were isolated in 47 (43.9%), 14 colonized with multidrug- (MDR) and 33 with extensively drug (XDR)-resistant bacteria or a mixture of MDR/XDR bacteria. Severity of liver disease and demographic characteristics were similar among groups. The 20 (42.6%) with DR vs 14 (23.3%) without had hepatic encephalopathy and/or spontaneous bacterial peritonitis episodes over the past 6 months (p = 0.034). One third of both DR and non-DR groups developed infection during follow-up but in only 7 and 5, respectively, the infection was microbiologically documented. In a 3-month-follow-up period, mortality was higher in patients colonized with XDR compared to those without (log rank p = 0.027). In multivariate analysis, colonization with XDR bacteria [HR = 1.074, (CI:1.024-1.126), p = 0.003] and MELD score [HR = 2.579 (1.109-5.996), p = 0.028] were independently associated with low survival. Asymptomatic GI colonization with DR bacteria is a risk factor for increased mortality in decompensated cirrhosis. Frequent hospitalizations for complications of the underlying disease and selective pressure induced by the use of antimicrobials are probably the main determinants.

RESUMO

In the WHO-EURO region, around 28 million people are currently living with chronic viral hepatitis, and 120,000 people die every year because of it. Lack of awareness and understanding combined with the social stigma and discrimination exacerbate barriers related to access to prevention, diagnosis and treatment services for those most in need. In addition, the persisting economic crisis has impacted on public health spending, thus posing challenges on the sustainable investment in promotion, primary and secondary prevention, diagnosis and treatment of viral hepatitis across European countries. The Hepatitis B and C Public Policy Association in cooperation with the Hellenic Center for Disease Prevention and Control together with 10 partner organizations discussed at the Athens High Level Meeting held in June 2014 recent policy developments, persisting and emerging challenges related to the prevention and management of viral hepatitis and the need for a de minimis framework of urgent priorities for action, reflected in a Call to Action (Appendix S1). The discussion confirmed that persisting barriers do not allow the full realisation of the public health potential of diagnosing and preventing hepatitis B and C, treating hepatitis B and curing hepatitis C. Such barriers are related to (a) lack of evidence-based knowledge of hepatitis B and C, (b) limited access to prevention, diagnosis and treatment services with poor patient pathways, (c) declining resources and (d) the presence of social stigma and discrimination. The discussion also confirmed the emerging importance of fiscal constraints on the ability of policymakers to adequately address viral hepatitis challenges, particularly through increasing coverage of newer therapies. In Europe, it is critical that public policy bodies urgently agree on a conceptual framework for addressing the existing and emerging barriers to managing viral hepatitis. Such a framework would ensure all health systems share a common understanding of definitions and indicators and look to integrate their responses to manage policy spillovers in the most cost-effective manner, while forging wide partnerships to sustainably and successfully address viral hepatitis.

RESUMO

BACKGROUND: Copper (Cu) and Zinc (Zn) are essential trace elements which play an important role in various biological processes. Zn deficiency is common in liver diseases while Cu deficiency is rarely reported. To determine whether serum Cu and Zn concentrations differed in acute hepatitis, compared to controls and investigate possible correlations of Cu and Zn values with etiology and severity of liver diseases. METHODS: Serum Cu and Zn concentrations were determined by air acetylene flame atomic absorption spectrometer in 40 patients (acute hepatitis A, B, C, autoimmune and drug induced hepatitis) and 150 healthy controls. RESULTS: Compared to healthy controls, significantly higher Zn levels were found in patients (106.5 µg/dl, P <0.01). Abnormal levels of either Cu and/or Zn were found in 48% of patients vs 23.3% of the controls (P =0.01). Ten patients had abnormal Zn and fourteen had abnormal Cu levels. There was a trend for the severe hepatitis cases to have abnormal Cu values and in this subgroup Cu and Zn were positively correlated with prothrombin time and alanine aminotransferase (ALT) levels, respectively. Cu and Zn levels did not differ statistically across groups of different etiologies. CONCLUSIONS: Abnormalities in Cu and Zn concentrations are common in acute hepatitis. Cu and Zn exhibited positive correlations with prothrombin time and ALT respectively, in severe cases.

RESUMO

Chronic hepatitis C (CHC) and end-stage liver disease are becoming an increasingly common cause of mortality in patients with congenital bleeding disorders, especially in the HIV-coinfected group. Combination of pegylated interferon (Peg-IFN) and ribavirin has recently become the treatment of choice for CHC. In this study, we evaluated the safety and efficacy of combination therapy with Peg-IFN plus ribavirin for the treatment of CHC in human immunodeficiency virus (HIV)- and HIV+ patients with congenital bleeding disorders. Between 2000 and 2004, 50 (18-68 years old) patients with CHC (19 HIV+) from two hemophilia centers were included in the study. They were treated with weekly subcutaneous administration of Peg-INF-alpha combined with 800-1,200 mg ribavirin daily, for 24-48 weeks depending on viral genotype. Response was evaluated at weeks 12, 24, 48 (end of treatment response) and 72 had sustained virological response). Overall, 22/50 patients (43.8%) had end of treatment response and 20/50 (40%) sustained virological response. HIV- patients responded similarly to the general population (58.1%), while HIV+ patients had very low response rates (10.5%). The high rate of discontinuation (36.9%) as a result of side effects contributed to the observed low response rate in the HIV+ group. The only factor strongly associated with sustained virological response in the HIV- patients was the reduction of HCV RNA at 12 weeks (p = 0.001). Patients with viral genotypes other than 1 had higher SVR rates, but this was not found to be statistically significant. Peg-INF plus ribavirin is safe for the treatment of CHC monoinfected patients with inherited bleeding disorders, with similar response rates to nonhemophiliacs. On the contrary, in HIV coinfected hemophilic patients under highly active antiretroviral therapy it is associated with severe toxicity and very poor sustained virological response rates. Careful evaluation and several considerations are needed before starting treatment in this population.

RESUMO

Of 22 patients with symptomatic giant liver hemangiomas referred for embolization, two females (52 and 74 years) had Kasabach-Merritt syndrome (KMS). Hematocrit values were observed to be 33% and 29%, platelets 4000 and 5400/mm(3), and fibrinogen 98 and 77 mg/dl, respectively. Lesion diameters were 7 and 14 cm, respectively. Hepatic angiography revealed excessive vascular lakes typical of cavernous hemangiomas. Microspheres of 40-300 microm were superselectively injected under fluoroscopic guidance until cessation of flow. Coil packing of the feeding hepatic artery was additionally used in one patient. The procedure was uneventful in both. Partial restoration of platelet count was observed immediately; fibrinogen levels and platelets were restored completely in one patient and partially in the other, without remissions at 2-year follow-up.

RESUMO

Hepatitis B virus (HBV) strains carrying the precore stop-codon mutation (A1896) have been considered among the predisposing factors for reactivation during chemotherapy for malignancies. The role of the T1762/A1764 basic core promoter (BCP) mutations has not been fully evaluated. We aimed to record any changes in HBV serological markers after reactivation, detect the presence of A1896 and BCP mutations and evaluate the type of cytotoxic drugs involved. We retrospectively screened eight patients presenting with HBV reactivation following chemotherapy for malignancies. The chemotherapy regimens used included corticosteroids (CSs), fludarabine and cyclophosphamide/adriamycine. The INNO-LiPA HBV PreCore kit was used for the detection of the A1896 and BCP mutations. Six patients who were hepatitis B surface antigen (HBsAg)-(+)/hepatitis B e antigen (HBeAg)-(-) before chemotherapy, had disease reactivation following a mean of four cycles of chemotherapy. Four survived and two died of hepatic failure. At the time of reactivation, all six patients carried the A1896 and five of them the BCP mutations. The remaining two patients were HBsAg-(-)/anti-HBs-(+)/anti-hepatitis B core (HBc)-(+)/HBeAg-(-) before chemotherapy. One of them reverted to HBeAg-(+) status but remained HBsAg-(-), while the other became HBsAg-(+)/HBeAg-(+), following three and eight cycles of fludarabine treatment, respectively. The former carried the A1896 and the latter the wild-type virus. Both died from causes associated with their haematological disease. All but one of our patients with HBV reactivation during chemotherapy carried the precore stop-codon and BCP mutations. Whether this occurs more frequently in such patients than those carrying the wild-type virus needs further investigation. Fludarabine should be added to the list of drugs inducing HBV reactivation. HBV reactivation following fludarabine treatment occurred in HBsAg-(-) patients who had been anti-HBs-(+).

RESUMO

The genetic heterogeneity of hepatitis B virus (HBV) (8 genotypes A-H) has been applied for tracing the route of HBV transmission and the geographical migration of HBV carriers but it also appeared to have clinical implications. The secondary structure of e encapsidation signal could explain why the precore mutant virus prevails in Mediterranean countries, where genotype D is most prevalent, while the wild type virus is frequent in Western countries, where genotype A is most prevalent. There is increasing evidence that patients infected with genotype C have more severe outcome of chronic liver disease than those infected with genotype B. Genotype B was associated with fulminant hepatitis and more severe episodes of acute exacerbation of chronic HBV infection. Patients infected with genotype B appeared to seroconvert earlier than those infected with genotype C. The hepatitis delta virus (HDV) has 3 genotypes (I, II, III) which are associated with different disease patterns. Genotype III is the most distantly related HDV genotype and is associated with the most severe outcome while genotype II with relatively mild liver disease. The most geographically widespread genotype is I and is associated with a broad spectrum of chronic liver disease. The hepatitis C virus (HCV) displays high genetic heterogeneity with six genotypes (1-6), multiple subtypes and quasispecies. This viral diversity has epidemiological and clinical implications and has been associated with the severity of liver disease, prognosis, response to treatment and failure to generate an effective protective vaccine. HCV genotype 1 is the predominant genotype in Western countries and has been associated with a low response rate to interferon-alpha (IFN-alpha) or to the combination of ribavirin and IFN-alpha. Consequently the duration of treatment has been tailored according to HCV genotype.

RESUMO

Immune thrombocytopenic purpura is an acquired disorder characterized by severe thrombocytopenia and caused by one or more antiplatelet autoantibodies. We present a case of a 20-year-old woman referred to our Unit for chronic hepatitis C virus (HCV) infection. At week 28 of treatment with interferon (alfacon-1), undetectable HCV RNA and transaminase levels within normal limits, the patient presented with immune thrombocytopenic purpura, which was successfully treated with immunoglobulin and methylprednisolone. Despite the high doses and long life of corticosteroid treatment HCV RNA remained undetectable.

RESUMO

The autoimmune lymphoproliferative syndrome (ALPS) or Canale-Smith syndrome is a recently described clinical entity consisting of chronic, non-malignant lymphadenopathy and hepatosplenomegaly together with hypergammaglobulinemia, positive autoantibodies and/or overt autoimmune diseases. It is caused by a genetic defect in the mechanism of programmed cell death (apoptosis) and is characterized by the presence of double-negative (TCR alpha/beta CD4- CD8-) T lymphocytes (DNT). Although well known in pediatric patients, ALPS is an unusual diagnosis in adults. The oldest reported patient was aged 54. We describe another two adult patients in whom a presenting autoimmune disease led to the diagnosis of ALPS.

RESUMO

Intestinal pseudo-obstruction (IPO) is a rare complication of systemic lupus erythematosus (SLE). We present a 32-year old female with SLE for seven years. She was admitted with profound fatigue, frequent vomiting, colicky abdominal pain, diarrhoea and intermittent dysuria for the past 12 months. Imaging studies revealed dilated small and large bowel loops with thickened intestinal wall and multiple fluid levels. Urinary tract involvement was also demonstrated. The patient responded well to immunosuppressive treatment. IPO in the context of SLE has been described only in anecdotal case reports. Half of the cases developed this complication during the course of lupus as in the present case. Concomitant ureterohydronephrosis was present in approximately two-thirds of the cases. Early recognition of the syndrome is necessary for the institution of the appropriate medical treatment and prevention of inappropriate surgical intervention.
