Intestinal colonization with resistant bacteria: a prognostic marker of mortality in decompensated cirrhosis.

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.

Addressing barriers to the prevention, diagnosis and treatment of hepatitis B and C in the face of persisting fiscal constraints in Europe: report from a high level conference.

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.

Five-Years Outcome Analysis of 142 Consecutive Hepatocellular Carcinoma Patients Treated with Doxorubicin Eluting Microspheres 30-60 µm: Results from a Single-Centre Prospective Phase II Trial.

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.

Pegylated interferon plus ribavirin combination therapy for chronic hepatitis C in patients with congenital coagulation disorders.

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.

Genetic heterogeneity of hepatitis viruses and its clinical significance.

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.

Iron overload in multiply transfused patients who are HIV seropositive.

AIMS: To assess histologically the amount of iron deposited in liver biopsy specimens from HIV positive patients; and to perform estimations of liver iron on tissue from patients with an increase in parenchymal stainable iron. To correlate the amount of blood transfused and the degree of iron overload. METHODS: Liver biopsy specimens (n = 120) from 109 HIV positive patients, 74 of whom had AIDS, were examined retrospectively and the amount of iron, as visualised with Perls's stain, was graded. Fibrosis was assessed using connective tissue stains. Estimations of liver iron were performed on tissue retrieved from paraffin wax blocks in cases with histological grade 3 or 4 iron overload. The amount of blood transfused before liver biopsy was determined from the notes for each patient. RESULTS: Fifteen of the 120 liver biopsy specimens had significantly increased amounts of iron in their hepatocytes, as assessed histologically, and this was confirmed in seven cases by measurement of liver iron. There was a close correlation between the amount of blood transfused and the degree of iron overload. In the initial biopsy specimens only one case showed portal tract expansion. Three of the five patients who had repeat biopsies, however, showed progressive fibrosis. CONCLUSION: Multiply transfused HIV positive patients may develop clinically important iron overload and are at risk of developing progressive fibrosis. Superimposed liver disease, especially viral hepatitis, in these high risk patients may exacerbate the effects of the iron overload.

Pleural effusion and pulmonary injury as an unusual complication to chemotherapy in non-small cell lung cancer patients.

We report the appearance of pleural effusion, or pulmonary failure after chemotherapy, followed by tumor reduction, in a small number of patients. Five hundred and fifty-four patients with lung cancer have undergone chemotherapy at our Institute during the last ten years. Three patients with non-small cell lung cancer (NSCLC), with locally advanced disease, exhibited an unusual consequence following cytotoxic drug treatment. Two patients with NSCLC had pleural effusion which improved within 2-3 weeks, together with tumor reduction, which allowed the continuation of treatment. One patient had pulmonary failure with pleural effusion and recovered within two weeks. Two of the three patients had positive cytology for cancer cells in the fluid. All three patients achieved partial remission with no repetition of the complication. The patients' recovery, response to treatment and the tumor reduction suggest that this complication was not due to disease progression.

Splenic infarct as a late complication of liver transplantation.

Splenic infarct is a rare complication of portal hypertension. It has been reported as an early complication after successful liver transplantation when portal pressure returns to normal and the splenic size progressively declines. It has not been reported as a late complication of liver transplantation. We describe the case of a 19-year-old patient with a splenic infarct which occurred 11 months after successful orthotopic liver transplantation for decompensated cryptogenic liver cirrhosis. Following transplantation, the patient was in excellent general health, liver function tests were normal, there was no clinical evidence of portal hypertension and the splenic size had decreased significantly compared to the pre-transplantation period, although it remained increased. The patient presented with high fever, left pleuritic pain and vomiting. The splenic size had not changed and left pleuritic exudate fluid collection was detected. A hypoechoic region of the spleen was demonstrated in the ultrasound examination corresponding to a hypodense lesion in the computerized tomography scanning. The patient recovered completely, with the disappearance of the infarct in the imaging studies in 2 months time. This case report indicates that a symptomatic splenic infarct can occur late following successful liver transplantation for liver cirrhosis despite lack of any evidence of residual portal hypertension at a time that splenomegaly has not yet regressed. The differential diagnosis from a splenic abscess in transplanted patients can be difficult but the final prognosis seems to be good.

A case of haemosuccus pancreaticus.

Haemosuccus pancreaticus (Wirsungorrhagia or pseudohaemobilia) is a rare complication of chronic pancreatitis. We describe a 48-year-old patient with alcohol-induced chronic calcific pancreatitis and recurrent episodes of severe upper gastrointestinal bleeding but without abdominal pain. Upper gastrointestinal endoscopy revealed fresh blood oozing from the ampulla of Vater. No pseudoaneurysms or pseudocysts were detected by arteriography or computerized tomography. The bleeding was attributed to pancreatic lithiasis. Following conservative treatment, there was no evidence of recurrence during a 24-month follow-up period. In conclusion, although a rare occurrence, haemosuccus pancreaticus should be considered in the differential diagnosis of all cases of obscure upper gastrointestinal bleeding in patients with chronic pancreatitis, whether or not accompanied by pain. A highly suggestive clinical history or X-ray findings and an endoscopic visualization of blood coming from the ampulla of Vater may suffice for the diagnosis, thus avoiding diagnostic and therapeutic errors. When haemosuccus pancreaticus occurs in patients without pseudoaneurysms or pseudocysts, it can be treated conservatively, thus obviating the need for pancreatectomy or arteriographic embolization.

Gliclazide-induced acute hepatitis.

There are few reports in the literature related to sulfonylurea-induced hepatotoxicity. We describe the case of acute hepatitis induced by gliclazide, a second generation sulfonylurea. A 60-year-old woman with diabetes mellitus (type 2) developed an acute icteric hepatitis-like illness 6 weeks after the initiation of gliclazide therapy. Other causes of acute hepatocellular necrosis were excluded. Liver histology showed marked portal inflammation with lymphocytes, monocytes and eosinophils, associated with lobular inflammation (indicative of a histological pattern consistent with drug-induced hepatitis). The drug was immediately withdrawn and the patient was given glibenclamide. The patient recovered clinically and, in less than 4 weeks, her serum bilirubin and aminotransferases returned to normal levels. We believe that this is the first description of acute hepatitis caused by an idiosyncratic adverse reaction to gliclazide or to one of its metabolites. In conclusion, this case strongly suggests that gliclazide can induce acute icteric liver necro-inflammation which may be misdiagnosed clinically as acute viral hepatitis. In patients who show abnormal liver function tests, the immediate discontinuation of gliclazide is recommended.

Fulminant hepatic failure as a presenting paraneoplastic manifestation of Hodgkin's disease.

Malignancies may uncommonly present as fulminant hepatic failure and, due to the rarity of such an occurrence, they may easily be overlooked as one of its possible causes. An unusual case of Hodgkin's disease presenting as a fulminant hepatic failure is reported. A 34-year-old man presented with an acute onset of liver failure characterized by jaundice, ascites, encephalopathy and bleeding diathesis. Chemotherapy was initiated, resulting in a dramatic improvement not only in the patient's level of consciousness, but also in prothrombin time. Unfortunately, he succumbed shortly after to disseminated candidiasis. A post-mortem needle liver sample revealed massive hepatocellular necrosis, but no liver infiltration by the neoplastic disease. We conclude that in Hodgkin's disease, involvement of the liver can be manifested as a syndrome of paraneoplastic fulminant hepatic failure. In such cases, liver transplantation is an absolute contraindication but urgent chemotherapy under antifungal surveillance can be life saving.

Cholestatic jaundice as a paraneoplastic manifestation of renal cell carcinoma.

Malignant diseases may cause cholestatic jaundice through either main bile duct obstruction or widespread hepatic metastasis. Renal cell carcinoma (hypernephroma, RCC) can cause a variety of paraneoplastic manifestations which can be the main presenting symptoms. Cholestasis, as a paraneoplastic syndrome, has been well described in patients with malignant lymphohyperplastic diseases. Non-metastatic nephrogenic hepatic dysfunction syndrome without jaundice has often been described in patients with hypernephroma (Stauffer's syndrome). Paraneoplastic cholestatic jaundice has not yet been described. We report, for the first time, two patients who presented with pruritus and cholestatic jaundice. During the diagnostic work-up, RCC was diagnosed. The renal tumour was an unexpected finding during computed tomographic (CT) scan. No clinical manifestations of hypernephroma, short of microscopic haematuria, were detected. Conjugated bilirubin, alkaline phosphatase and gamma-glutamyltranspeptidase were markedly increased. No hepatic metastasis or main bile duct obstruction were detected by appropriate investigations. After radical nephrectomy, liver abnormalities disappeared rapidly. We conclude that RCC should be included among neoplasms causing not only anicteric intrahepatic cholestasis but also frank jaundice as part of a paraneoplastic syndrome. The differential diagnosis from hepatic metastasis, main bile duct obstruction or other causes of jaundice is of clinical importance and of prognostic value. Patients with unexplained cholestasis should be investigated for malignant diseases including hypernephroma.

Autoimmune hepatitis associated with the antiphospholipid syndrome.

The antiphospholipid syndrome has rarely been described in patients with autoimmune hepatitis. Two cases with type I autoimmune hepatitis and antiphospholipid syndrome are presented. The first case is that of a 53-year-old Caucasian female with a history of arterial thrombosis and fetal loss who was submitted to clinical and laboratory testing due to persistent transaminasaemia and was found to have autoimmune hepatitis. Antiphospholipid antibodies (anticardiolipin antibodies and lupus anticoagulant) were positive. The second case is that of a 31-year-old Caucasian woman with a history of autoimmune hepatitis who was submitted to laboratory testing due to a second-trimester fetal death, revealing an increased activated partial thromboplastin time and positive antiphospholipid antibodies. In conclusion, secondary antiphospholipid syndrome may accompany autoimmune hepatitis.

Polymyositis associated with primary biliary cirrhosis.

The coexistence of polymyositis (PM) and primary biliary cirrhosis (PBC) is rare; only nine cases have been described in English literature. We report a case of a 46-year-old woman presenting with these two autoimmune diseases. The diagnosis of PM was based on the symmetrical, proximal limb muscle weakness, elevated muscle enzymes and was confirmed with the electromyography and muscle biopsy. The diagnosis of PBC was based on the increased serum levels of alkaline phosphatase, gamma glutamyltransferase, IgM immunoglobulin, the presence of antimitochondrial antibodies and diagnostic liver biopsy.

The autoimmune lymphoproliferative syndrome (Canale-Smith) in adulthood.

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.

Pituitary non-secreting macroadenoma apoplexy in an adolescent. patient report and review of the literature.

Pituitary macroadenomas are rare in children and adolescents, and when encountered are usually hormone secreting. Symptomatic pituitary non-secreting macroadenoma apoplexy in an adolescent is rare and potentially life-threatening. A 15 year-old patient is described, hospitalized due to headache, fever and photophobia 4 days prior to admission. A meningeal syndrome was postulated, based on clinical examination and cerebrospinal fluid testing. However, clinical examination and hormone testing revealed partial failure of the anterior pituitary. Computed tomography of the brain demonstrated a space-occupying lesion of the pituitary. Magnetic nuclear resonance imaging suggested the presence of a pituitary macroadenoma. Hypophysectomy was performed. Histological examination revealed an extensive infarction of a pituitary adenoma. Hormonal substitution with thyroxine and corticosteroids was administered. This report emphasizes that pituitary non-secreting macroadenoma apoplexy may rarely be the cause of headache and fever in an adolescent, thus causing difficulties in differential diagnosis from acute meningitis.

Prolonged cholestatic jaundice after endoscopic retrograde cholangiography.

The main complications of endoscopic retrograde cholangiography and sphincterotomy are bleeding, pancreatitis, perforation and sepsis. Two cases of unexplained prolonged cholestatic jaundice in patients who underwent endoscopic retrograde cholangiography (ERC) for biliary obstruction due to choledocholithiasis are reported. The patients were admitted because of right upper quadrant pain, vomiting and jaundice. Laboratory tests showed increased levels of total and conjugated serum bilirubin and increased alkaline phosphatase. Ultrasound examination showed cholelithiasis and choledocholithiasis with bile duct dilatation. ERC with sphincterotomy was performed and gallstones obstructing the common bile duct were removed endoscopically. Following ERC and despite complete patency of the biliary tree, a progressive increase of total and conjugated bilirubin and of alkaline phosphatase was noted, associated with itching and total stool discoloration. The insertion of nasobiliary drain did not improve the jaundice. Prednisolone treatment for 12 days was associated with progressive restoration of serum bilirubin alkaline phosphatase to normal levels. It was postulated that the radiocontrast material used may have acted toxically on the liver with disruption of the canalicular plasma membrane. It is proposed that intrahepatic cholestasis should be added in the list of complications of endoscopic retrograde cholangiography.

Clinical significance of quantitative anti-HBc IgM assay in acute and chronic HBV infection.

The applicability and clinical usefulness of anti-HBc IgM quantification in acute and chronic hepatitis type B by a single run of undiluted sera is largely unknown. Serum anti-HBc IgM concentrations were measured in 153 patients with various forms of acute and chronic HBV infection by a new commercially available qualitative ELISA/2-step capture assay applying streptavidin technology. The absorbance values were expressed in anti-HBc IgM U/ml using a calibration curve produced by a series of anti-HBc IgM standards. The results were compared with those obtained with another second generation qualitative anti-HBc IgM method also in undiluted sera applying the Microparticle Enzyme Immune Assay (MEIA). In acute hepatitis B, anti-HBc IgM was always > 600 U/ml (median: > 800 U/ml) declining to median values of 135 and 85 U/ml at months 3 and 6, respectively. Values above 600 U/ml were seen in 4 out of 20 (20%) HBsAg carriers with episodes of severe HBV-induced liver damage resembling acute hepatitis B (group 2) and in 2 out of 35 (5.6%) patients with HBV induced chronic active hepatitis (group 3). Values above 100 U/ml, representing the cutoff levels for the diagnosis of acute hepatitis B in the qualitative assays, were detected in 55% (11/20) and 45.7% (16/35) of the above patients of groups 2 and 3, respectively. Anti-HBc IgM was negative or under 20 U/ml in 96.7% (29/30) of HBsAg carriers with acute or chronic liver damage unrelated to HBV (HDV, HCV or drug-induced) and in 91% (41/45) of HBsAg carriers with persistently normal ALT levels.(ABSTRACT TRUNCATED AT 250 WORDS)

Zinc deficiency in mild hypertensive patients treated with diuretics.

Mean hair zinc was found to be significantly lower in 20 mild hypertensive patients treated with thiazides for 6-36 months than in 19 mild hypertensive patients who had not been given diuretics for at least six months before study. Mean serum zinc did not differ significantly between the two groups. Chronic diuretic treatment can result in zinc deficiency through enhanced urinary excretion of zinc.

Abnormalities in Cu and Zn levels in acute hepatitis of different etiologies.

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.
