    Management option of hepatic echinococcosis represents a major challenge for a surgeon. The aim of the study was to evaluate surgical treatment of patients with hepatic echinococcosis at the surgery department of the regional hospital in Prizren (Kosovo). The medical records of 22 patients operated for hepatic echinococcosis in our department during a four year study period (2009–2013) were retrospectively reviewed. Apart from the total of 5850 operated patients, 22 cases were diagnosed for liver echinococcosis (0.4%). The most affected age group was from 26 to 50 years (54.5%). Female gender, 16 cases (73%), and patients living in rural places, 14 patients (64%), dominated significantly. The most affected region was Municipality of Dragash. All patients underwent ultrasonography, 13 patients underwent CT scans and 5 patients MRI of abdomen. The mean preoperative ultrasonographic diameter of cysts was 9.5 cm and maximal 21 cm. Cysts were most often localized in right hepatic lobe (77%) and subcostal laparotomy was most commonly performed (82%). The performed surgical procedures were: endocystectomy and partial pericystectomy with omentoplication according to Papadimitris (73%), endocystectomy and capitonnage and endocystectomy with external drainage (14%). The laparoscopic approach was used only in one patient. In conclusion, hepatic echinococosis was not common among operated patients at our surgery department. Subcostal laparotomy with endocystectomy and partial pericystectomy with omentoplication according to Papadimitris was most commonly used. Exact distribution of echinococcosis is needed to be analyzed with a larger cohort study including all surgery units in the country and with a longer monitoring. PMID:25568800

    Full Text Available Hepatic echinococcosis has become a major threat to human health. Hepatic alveolar echinococcosis caused by Echinococcus multilocularis infection has the features of slow and insidious onset, a high probability of surgery, slow postoperative recovery, and many complications and thus does great harm to humans. Most of the patients with hepatic alveolar echinococcosis also have varying degrees of malnutrition on admission, which is closely associated with surgical tolerance, postoperative rehabilitation, and the development of complications. However, the pathogenesis of malnutrition in patients with hepatic alveolar echinococcosis remains unknown. This article elaborates on possible mechanisms and points out that malnutrition in such patients is a result of various factors and complex mechanisms.

    Three patients are described with hepatic involvement by Echinococcus granulosus, complicated by spontaneous rupture into the biliary tract. Abdominal computed tomography, showing the cystic wall, the presence of wall calcifications, daughter cysts and wall enhancement, provided a correct diagnosis of hepatic hydatidosis in all patients. Dilatation of the bile ducts with the presence of intraluminal material was clearly shown by sonography and endoscopic retrograde cholangiography. On sonography, the intraluminal material appeared as amorphous, sludge-like hydatid sand, and as daughter cysts. On ERCP, the intrabiliary parasitic material appeared as non-homogeneous, irregularly shaped and mobile filling defects. Other findings at ERCP were displacement and distortion of intrahepatic bile ducts by the hepatic cysts and a mild dilatation of the pancreatic duct. (Auth.)

    Full Text Available Hepatic alveolar echinococcosis (HAE is a zoonotic parasitic disease that seriously threatens the population in western China and compromises patients′ quality of life. With the continuous improvement in radical resection rate in recent years, late-stage HAE patients that were incurable in the past now have the opportunity for radical resection. However, patients who are not suitable candidates for radical resection still suffer from various complications and poor quality of life. Therefore, HAE is still considered a refractory and complex disease. The simple empirical treatment model provided by traditional professional discussion is unable to satisfy the treatment of advanced refractory HAE as it is unable to integrate specialized, standardized clinical skills for diagnosis and treatment. Multidisciplinary individualized treatment (MDT organically integrates the advantages of the available treatment into a reasonable individualized comprehensive treatment regimen. This review summarizes the advances in MDT for HAE as the best option to increase long-term survival, and suggests MDT as the first-line treatment for late-stage refractory hepatic alveolar echinococcosis.

    A total of 24 cases of hepatic alveolar echinococcosis (HAE) due to Echinococcus multilocularis was assessed by US and CT. The diagnosis was confirmed in all cases by immunologic and histologic study. Both US and CT patterns of HAE showed changes of liver morphology in both contour and size. Abnormal areas of parenchyma were nodular or in fields, irregular, heterogeneous, and basically echogenic. Clustered microcalcifications were encountered within the abnormal parenchymal fields in 50% of cases, and necrotized zones occurred in 40% of cases. Dilatation of intrahepatic bile ducts was commonly seen, especially on US; hilar involvement was frequent. Follow-up by both techniques can display increases of primary lesions, occurrence of new foci, and local or regional extensions. Precise evaluations of the lesions arising from correlative use of US and CT permits adequate therapeutic management.

    Full Text Available Hepatic alveolar echinococcosis (HAE is a parasitic disease characterized by invasive growth. Major treatment methods include pharmacotherapy and surgical treatment, and surgical treatment mainly includes radical hepatectomy and palliative surgery. Radical hepatectomy is the first choice, and palliative surgery is mainly used to alleviate disease conditions and complications. Pharmacotherapy also plays an important role in the delay and control of HAE. In recent years, autologous liver transplantation has been used in the treatment of HAE and has become an effective therapy for end-stage HAE patients who cannot be cured by routine surgery. This article introduces the indications and advantages/disadvantages of radical hepatectomy and palliative surgery, as well as the experience in the application of multidisciplinary treatment, the concept of fast-track surgery, and autologous liver transplantation in the treatment of HAE patients, in order to provide a reference for the treatment of HAE.

    Little is known about the long-term effectiveness of albendazole in the medical therapy of non-complicated hepatic cystic echinococcosis (HCE) in resource-constrained settings. We performed a retrospective review of patients starting albendazole for HCE in Lima, Peru from January 1997 to December 2007. Patients successfully recontacted underwent chart abstraction and clinical and ultrasonographic reevaluation. Descriptive statistics were used to delineate patient characteristics and treatment effectiveness at the conclusion of albendazole and after reevaluation. Patients (N = 27) were primarily female, mean age was 51. Initial treatment success at albendazole conclusion was 26% (N = 7) per patient and 37.5% (N = 24) per cyst. After 3.8 ± 2.5 years, albendazole success was 34% (N = 9) per patient and 40% (N = 24) per cyst. We found a gap in the effectiveness of albendazole HCE therapy compared with the efficacy reported in clinical trials. This underscores the need for further investigation into alternate therapeutic strategies for this neglected disease. PMID:22144447

    Purpose: To analyze the CT features and evaluate albendazole chemotherapy of hepatic alveolar echinococcosis with computed tomography (CT). Methods: Twenty-one patients of hepatic alveolar echincoccosis were diagnosed by epidemiological, clinical, serological tests, and studied with US and CT. Twenty patients were followed up by CT scanning from 1 to 9 years (mean 3.9 years) after albendazole chemotherapy. Results: CT scanning of liver before treatment displayed heterogeneous hypodense lesions, with irregular, obscure contour and calcifications According to CT features, the hepatic lesions were divided into 3 forms: solid mass in 7 cases, pseudocyst in 6 cases and mixed in 8 cases. Three patients had contrast study. The hepatic lesions were not markedly enhanced, but the lesions were seen more clearly and appeared more extensive. In follow-up examination of 20 cases, 4 were apparently cured, 5 improved, 5 stabilized, and 6 cases remained pseudocyst. Conclusion: CT scanning was of value not only for diagnosis of hepatic alveolar echinococcosis, but also useful in evaluation of chemotherapeutic efficacy

    Objective: To analyze the multi-slices spiral CT (MSCT) findings of hepatic alveolar echinococcosis (HAE), and to evaluate the value of MSCT for diagnosis of HAE. Methods: Twenty-six cases with HAE were scanning by MSCT. The raw data were transmitted to advanced workstation for reconstruction imaging. Correlated studies were made between the CT features and pathology or other imaging results. Results: Altogether 28 lesions were detected. They all revealed as heterogeneous hypodense mass with ill-defined boundary in plain CT but were easily being distinguished from surrounding parenchyma after contrast medium injection. Characteristics of the lesions include different amount of calcification (26/26), liquefied necrosis in center area (20/26), peripheral lacunae or alveolar signs (15/26 ), compensatory hypertrophy of healthy hepatic part (18/26) and the retraction in the involved hepatic lobe or segment (12/26). The lesions that located at or extended to hepatic hilum caused dilatation of intra-hepatic biliary ducts (9/26), splenomegaly (12/26 ), and ascites (1/26). MSCT angiography (CTA) depicted signs of abnormalities of hepatic vessels such as compression, displacement, encasement and occlusion. Compared with findings of operation, the sensitivity, specificity and positive prediction value of CTA for evaluating the hepatic artery system disorders were 88%, 96% and 93%, respectively; and for portal venous system were 95%, 100% and 95%, respectively; while for hepatic venous system were 96%, 86% and 96%, respectively. Conclusion: MSCT is able to comprehensive display the CT features and vessels complication of HAE. It provides reliable imaging for both accuracy diagnosis and proper treatment of the disease.

    Objective: Alveolar echinococcosis (AE) is a rare life-threatening parasitic infection. Computed tomography perfusion (CTP) imaging has the potential to provide both quantitative and qualitative information about the tissue perfusion characteristics. The purpose of this study was the examination of the characteristic features and feasibility of CTP in AE liver lesions. Material and Methods: CTP scanning was performed in 25 patients who had a total of 35 lesions identified as AE of the liver. Blood flow (BF), blood volume (BV), portal venous perfusion (PVP), arterial liver perfusion (ALP), and hepatic perfusion indexes (HPI) were computed for background liver parenchyma and each AE lesion. Results: Significant differences were detected between perfusion values of the AE lesions and background liver tissue. The BV, BF, ALP, and PVP values for all components of the AE liver lesions were significantly lower than the normal liver parenchyma (p<0.01). Conclusions: We suggest that perfusion imaging can be used in AE of the liver. Thus, the quantitative knowledge of perfusion parameters are obtained via CT perfusion imaging. PMID:29531482

    In this study, we aimed to compare the clinical efficacy of liposomal albendazole (L-ABZ) and tablet-albendazole (T-ABZ) for the treatment of human hepatic cystic echinococcosis (CE). Sixty patients with single cyst (CE1) or daughter cyst (CE2) were included in this study and were nonrandomly divided into the L-ABZ group (n = 30, 10  mg/kg per day, p.o., b.i.d.) and T-ABZ group (n = 30, 12-20 mg/kg per day, p.o., b.i.d.), respectively. The treatment duration lasted for 6 months, during which dynamic follow-up was carried out to evaluate the clinical efficacy through calculating the total effective rates (TERs). Measurement data and numerous data were analyzed by the chi-square test. Two-sided tests were performed for all the statistical tests. In our study, 2 patients were lost in the follow-up in the L-ABZ group. One patient was lost in the follow-up in the T-ABZ group, and 1 patient was withdrawal from the study due to receiving surgery. Significant difference was identified in the 3-month TERs of L-ABZ group and T-ABZ group (33.3% vs 76.7%, P  0.05). Based on our study, both T-ABZ and L-ABZ are effective for treating human CE. The TER in the L-ABZ group is superior to that of T-ABZ.

    Objective: To explore the correlation of CT perfusion imaging with microvessel density (MVD) and vascular endothelial growth factor (VEGF) in hepatic alveolar echinococcosis (HAE). Methods: Multi-slice spiral CT perfusion imaging was performed in 27 patients with HAE. Time-density curves(TDC) of the HAE peripheral area was drawn from the region of interest (ROI) with perfusion functional software. CT perfusion parameters including blood flow (BF), blood volume (BV), mean transit time (MTT) and permeability surface area product (PS) were calculated. MVD and VEGF expression of pathological specimens were examined by immunohistochemical staining with anti-CD34, anti-VEGF monoclonal antibody. The CT perfusion parameters, MVD and VEGF were compared in different types of TDC with t test. The correlation of CT perfusion parameters with MVD and VEGF were analyzed with Spearman test. Results: In this group, 21 cases which TDC lower than that of the liver were classified as type Ⅰ, the others 6 cases TDC higher than the liver were of type Ⅱ TDC. TDC perfusion parameters of the two types were as follows, BF: (111.7±27.6), (158.9±39.5) ml · 100 g -1 · min -1 , BV: (15.1±6.2) , (26.8±8.4) ml/100 g, MTT: (7.0±4.4), (7.7±3.1) s, PS: (51.7±17.3), (51.0±20.5) ml ·100 g -1 · min -1 . The significant differences of BF, BV and MVD [(20.5±5.4)/HP, (37.2±7.5)/HP, respectively] were found between two types (t=-7.897, -18.783, -5.223, P 0.05). The correlation was found between the MVD and BF and BV in the type Ⅱ TDC group (r=0.789 and 0.878, respectively) and no correlation was found between MVD and each CT perfusion parameters in the type Ⅰ TDC group (P>0.05). There was no correlation between the VEGF expression and CT perfusion parameters in two types of TDC (P>0.05). Conclusion: CT perfusion imaging with different type of TDC reflected different situation of angiogenesis in HAE peripheral area, which could be a potential technique to illustrate the

    The current study was carried out to evaluate the prophylactic and therapeutic effects of Allium sativum on experimental cystic echinococcosis by measuring the serum nitric oxide level and studying hepatic histopathological changes. The experimental animals were divided into five groups, ten mice in each, group (I): prophylactic; group (II): therapeutic; group (III): prophylactic and therapeutic; group (IV): infected nontreated; group (V): non infected non treated. The results showed that serum nitric oxide was significantly increased as a result of infection in all infected groups compared to group V. Statistical significant difference was noted in serum nitrate level in group I at 1st and 8th week post infection compared to the same time interval in group IV. In group II, statistical significance was noticed only at the 1st week post infection. Statistical significant difference was noted in serum nitrate level in group III at 1st, 4th, 6th and 8th week post infection compared to same time interval in group IV. Hydatid cysts developed in livers of mice of group IV as early as 4 weeks of infection while no cysts were found in groups I,II and III. Histopathologically there were moderate pathological changes in group I and group II as hepatocytes showed moderate steatosis, moderate venous congestion and inflammatory cellular infiltrate with foci of degeneration and necrosis. While livers of mice of group III showed mild steatosis, mild venous congestion, mild inflammatory cellular infiltrate, no necrosis and no biliary hyperplasia. Accordingly, that garlic (Allium sativum) may be a promising phototherapeutic agent for cystic echinococcosis.

    Full Text Available The problem of echinococcosis, despite the progress made in its diagnosis and treatment, currently remains poorly understood and highly relevant in pediatric Parasitology. Studies of many authors show that in recent years the number of patients with echinococcosis not only universally recognized endemic foci, but also among people in the European region, including in countries such as Romania, Germany, Austria. However, studies on the prevalence and structure of echinococcosis among children in Ukraine, are not held. Despite the large number of papers devoted to the treatment of echinococcosis, the problem of the treatment of this disease in children is still far from its final decision. Usually offered surgical treatment, which is not possible with multiple lesions of the liver or other organs. All this shows the relevance and importance for practical public health issues for further study of diagnosis and treatment of echinococcosis in children. The purpose of the study. A comparative analysis of the diagnostic efficacy of X-ray and ultrasound method in the diagnosis of echinococcosis in children. Material & methods. This work is based on a survey of 39 children with hepatic echinococcosis, were examined at the Department of Medical Parasitology and Tropical Diseases Kharkiv Medical Academy of Postgraduate Education from 2005 to 2015. Boys was 1.5 times greater (59.5% than girls - 40.5%. Children under five years of age accounted for only 4.0% of all patients, due to their limited contact with the environment when compared with older age. The greatest risk of disease was in the 10- 13 years of age, the number of children in the group reached 40.3% of the patients. The vast majority of patients (89.6% lived in rural areas. In this case, the parents of sick children from the village were engaged in farming, were in personal use livestock, dogs, which probably contributed to the invasion.

    Cystic echinococcosis is a chronic, complex, and neglected disease. The need for a simple classification of cyst morphology that would provide an accepted framework for scientific and clinical work on cystic echinococcosis has been addressed by two documents issued by the WHO Informal Working Group on Echinococcosis in 2003 (cyst classification) and in 2010 (Expert consensus for the diagnosis and treatment of echinococcosis). Here we evaluate the use of the WHO Informal Working Group on Echinococcosis classification of hepatic cystic echinococcosis, the acceptance by clinicians of recommendations regarding the use of albendazole, and the implementation of the long-term follow-up of patients with hepatic cystic echinococcosis in the scientific literature since the WHO Informal Working Group on Echinococcosis recommendations were issued. Of the publications included in our review, 71.2% did not indicate any classification, whereas 14% used the WHO Informal Working Group on Echinococcosis classification. Seventy-four percent reported the administration of peri-interventional albendazole, although less than half reported its modality, and 51% the length of patient follow-up. A joint effort is needed from the scientific community to encourage the acceptance and implementation of these three key issues in the clinical management of cystic echinococcosis.

    In order to ascertain the typical computed tomographic findings of hepatic alveolar echinococcosis, 24 computed tomograms of 19 patients were evaluated. The liver was involved in all cases whereas the diaphragma was infiltrated in 32%, and the retroperioteneal area in 42%. The right liver lobe was affected in 65%. Both before and after intravenous bolus contrast medium administration, the lesions were mainly inhomogeneous and of low density; a masking of the lesions due to the contrast medium administration was not observed; the enhancement pattern was irregular. Calcifications were detected in 96% of the cases, cystic structures in 50%, and cholestasis in 54%. On the basis of the crucial finding of calcifications in combination with the other typical observations, CT seems to be very suitable for the evaluation of hepatic alveolar echinococcosis. (orig.)

    Full Text Available Echinococcosis, commonly called as hydatid disease, is a parasitic infestation caused by the larva of the genus Echinococcus in human. Isolated occurrence of Echinococcosis without any evidence of visceral disease is very rare. A thorough search of the literature revealed only 11 cases of isolated cervical Echinococcosis. We report here a very rare case of isolated hydatid cyst in a 45-year-old female patient, who presented with swelling in right cervical region about 5 cm below the angle of mandible with no evidence of the disease elsewhere in the body. The case was diagnosed on fine needle aspiration cytology. The diagnosis was further supported by histopathology. We propose that the treating physician should also consider the differential diagnosis of Echinococcosis in the presence of an asymptomatic soft tissue mass, especially when the patient lives in an endemic area.

    To compare the value of MRI and CT in evaluating hepatic alveolar echinococcosis a study was conducted on 30 patients. The liver was initially affected in all patients. At the time of examination, 15 patients had undergone partial liver resection. MRI showed no advantage over CT in demonstrating an echinococcal mass lesion. MRI was superior in identifying concomitant pathological changes of the intrahepatic and extrahepatic venous system due to the intrinsic contrast of vascular structures. However, CT was superior in identifying calcifications, an important attribute of the disease. MRI should only be used in imaging alveolar echinococcosis of the liver if diagnostic questions remain open after CT, in particular questions concerning venous pathology. MRI may also be used to replace CT in patients with a contraindication to urographic contrast material. (orig.) [de

    The computer tomographic appearances and differential diagnosis in 22 patients with echinococcosis are described; of these, twelve were of the cystic and ten of the alveolar type. The computer tomographic appearances are characterised by the presence of daughter cysts (66%) within the sharply demarkated parasitic cyst of water density. In the absence of daughter cysts, a definite aetiological diagnosis cannot be made, although there is a tendency to clasification of the occassionally multiple echinococcus cysts. The computer tomographic appearances of advanced alveolar echinococcosis are characterised by partial collequative necrosis, with clacification around the necrotic areas (90%). The absence of CT evidence of partial necrosis and calsification of the pseudotumour makes it difficult to establish a specific diagnosis. The conclusive and non-invasive character of the procedure and its reproducibility makes computer tomography the method of choice for the diagnosis and follow-up of echinococcosis.

    Full Text Available Hydatidosis is a common infestation caused by Echinococcus spp. Solitary hydatid cyst of the lung is not uncommon but coexistence of two or more pulmonary cysts are less common. These cysts may drain into the bronchial tree or very rarely into the pleural cavity which causes a poor outcome. Certain people such as slaughters, tanners, stockbreeders, shepherds, butchers, veterinarians and all whose job makes them to work closely with animals are at higher risk of the infection and developing echinococcosis. Herein, we present a 14-year-old shepherd who developed severe chest pain and hydropneumothorax following a minor trauma to his chest. He had two pulmonary hydatid cysts, one of which drained to the left pleural cavity and caused the symptoms. Another cyst was complicated during his hospital course. The patient was treated surgically, received albendazole and discharged home uneventfully. A high index of suspicion is of utmost importance for the correct diagnosis and treatment of hydatid disease in hyperendemic areas and in those whose occupation might put them at a higher risk of contraction of hydatid disease.

    Echinococcosis has a worldwide geographical distribution with endemic foci on every inhabited continent. Due to the frequent outbreaks in different parts of Pakistan in the recent past, echinococcosis is being described as a neglected tropical disease and is considered one of the most neglected parasitic diseases in the country. In endemic regions, predominantly settings with limited resources, there are high numbers of echinococcosis patients, as these communities do not have access to appropriate treatment. In Pakistan, there are limited reports on echinococcosis. The disease is prevalent in human and livestock, but this has not been sufficiently explored yet. Pakistan is an agricultural country and due to the disease's zoonotic mode of transmission, there is a dire need of future research on it. The present paper is an effort to highlight the importance of echinococcosis in Pakistan. There is a dire need for future research on echinococcosis in Pakistan as very few investigations had been carried out on this topic thus far. The prevalence of the disease in neighbouring countries highlights that Pakistan might be at severe risk of this zoonotic infection and further supports the need for more research. In Pakistan, the majority of the population lives in rural areas with limited acess to proper hygienic/sanitary facilities. These conditions favour the outbreak of diseases such as echinococcosis. The limited available data could result in higher outbreaks in the future, and thus cause the already weak healthcare system to overburden. The country has a meagre annual budget for health, which is being spent on known infections such as polio, dengue fever and hepatic viral infections. A proper surveillance system for echinococcosis is required across the country as treatment is usually expensive, complicated and may require extensive surgery and/or prolonged drug therapy. Development of new/novel drugs and other treatment modalities receives very little, if any

    Paul R Torgerson

    Full Text Available BACKGROUND: Human alveolar echinococcosis (AE is known to be common in certain rural communities in China whilst it is generally rare and sporadic elsewhere. The objective of this study was to provide a first estimate of the global incidence of this disease by country. The second objective was to estimate the global disease burden using age and gender stratified incidences and estimated life expectancy with the disease from previous results of survival analysis. Disability weights were suggested from previous burden studies on echinococcosis. METHODOLOGY/PRINCIPAL FINDINGS: We undertook a detailed review of published literature and data from other sources. We were unable to make a standardised systematic review as the quality of the data was highly variable from different countries and hence if we had used uniform inclusion criteria many endemic areas lacking data would not have been included. Therefore we used evidence based stochastic techniques to model uncertainty and other modelling and estimating techniques, particularly in regions where data quality was poor. We were able to make an estimate of the annual global incidence of disease and annual disease burden using standard techniques for calculation of DALYs. Our studies suggest that there are approximately 18,235 (CIs 11,900-28,200 new cases of AE per annum globally with 16,629 (91% occurring in China and 1,606 outside China. Most of these cases are in regions where there is little treatment available and therefore will be fatal cases. Based on using disability weights for hepatic carcinoma and estimated age and gender specific incidence we were able to calculate that AE results in a median of 666,434 DALYs per annum (CIs 331,000-1.3 million. CONCLUSIONS/SIGNIFICANCE: The global burden of AE is comparable to several diseases in the neglected tropical disease cluster and is likely to be one of the most important diseases in certain communities in rural China on the Tibetan plateau.

    2014-01-01

    Objectives The present study was designed to gain information about the ultrasonographic features of livers with cystic echinococcosis, as well as to evaluate the use of ultrasonography for diagnosis of such disease in sheep. Design This was a retrospective study during the period April 2011 to March 2013. Participants A total of 22 Baladi sheep (aged three to six years) were included in this study. Based on clear hepatic ultrasonographic findings, all animals were classified into two groups: those with hepatic cysts (n=9) and without liver cysts (healthy liver, n=13). Results Biochemically, serum concentrations of γ-glutamyl transferase, aspartate aminotransferase, total bilirubin and globulins were significantly increased (P<0.01), while albumin was lowered (P<0.01) in sheep with cystic livers. Ultrasonographic findings of diseased sheep livers revealed the presence of rounded, anechoic and unilocular hydatid cysts with ellipse circumference ranged from 6–10 cm. The borders of cysts were mostly well defined. The interior of cysts contained echogenic particulate materials, septations, or fine echoes. At the 10th intercostal space, the ventral margin, size, thickness and angle of livers were higher (P<0.01), while the diameter of portal vein was lower (P<0.01) in sheep with liver cysts than control ones. Furthermore, at the 9th intercostal space, the circumference of the gall bladder was decreased in sheep with hepatic cysts (P<0.01). The sensitivity, specificity, and positive and negative predictive values of ultrasonography for diagnosis of hepatic hydatid cysts were 80 per cent and 100 per cent, and 100 per cent and 83 per cent, respectively. Conclusions Cystic echinococcosis is associated with a number of anatomical alterations in the liver tissues that can be easily recognised by ultrasound. Furthermore, ultrasonography alone or in combination with analysis of biochemical parameters reflecting liver function could be helpful for diagnosis of hepatic

    Objective: To analyze the CT findings of pelvic cystic echinococcosis, and to assess the value of CT examination. Methods: Twenty-one cases of pelvic cystic echinococcosis, confirmed by clinical and pathological results, underwent CT scanning. CT characters were analyzed and compared with pathology. Results: Simple cystic echinococcosis appeared as single or multiple cystic lesions with round or oval shape, smooth boundary, and no enhancement after contrast medium administration in 3 cases; Different number and size of daughter cysts were detected inside the lesion in 17 cases; Ruptured lesions showed 'double wall', 'water snake', or 'flow ribbon' signs in 4 cases; Increase density of contents and enhanced cystic wall were demonstrated in 2 cases with companied infections. In 8 cases, calcification occurred on the cystic wall or extended inside the content. Conclusion: CT could accurately demonstrate the location, appearance, internal structure, and adjacent situation of the cystic echinococcosis, providing valuable information for correct diagnosis and treatment

    Full Text Available The lack of specificity of clinical and laboratory manifestations of echinococcosis allocates to the fore diagnostic tool methods of research, which are at present leading in identifying the disease.The widespread introduction into clinical practice of modern highly informative instrumental methods such as ultrasonography (US and computed tomography (CT, significantly improved the early detection of liver echinococcosis. In conjunction with the serological reactions to echinococcosis they allow in most cases the diagnosis of the disease. However, false-negative results of serological tests in more than 10–20 % of the patients and the difficulty of differential diagnosis with small brush size and "pseudotumoral" forms of ultrasound often lead to delayed diagnosis, and thus to a deterioration of treatment results. Moreover, failure to identify at an early stage of echinococcosis virtually eliminates the possibility of conservative treatment of echinococcosis without performing surgery.It is given the profound immune disorders in patients with echinococcosis, treatment should be complex and along with the surgical removal of hydatid cyst should be included in it and biostimulating.

    The application of modern immunodiagnostic or molecular diagnostic techniques has improved the diagnosis of the taeniid cestode infections, echinococcosis and taeniasis. One particularly promising approach is the detection of parasite-specific antigens in faeces (coproantigens). This approach has been applied to both Echinoccocus and Taenia species and it has gained increasingly widespread use. Taeniid coproantigen tests are based on either monoclonal or polyclonal antibodies raised against adult tapeworm antigens. These tests have the following common characteristics; they are largely genus-specific, specificity is high (>95%), parasite antigen can be detected in faeces weeks prior to patency, levels of coproantigen are independent of egg output, coproantigen is stable for days at a range of temperatures (-80 degrees C to 35 degrees C), for several months in formalin-fixed faecal samples, and coproantigen levels drop rapidly (1-5 days) following successful treatment. In the genus Taenia, most work has been done on Taenia solium and coproantigen tests have reliably detected many more tapeworm carriers than microscopy. For Echinococcus species, there is a broad positive correlation between test sensitivity and worm burden with a reliable threshold level for the test of >50 worms. Characterisation of taeniid coproantigens in order to further improve the tests is ongoing. Studies indicate taeniid coproantigens to include high molecular weight (>150 kDa), heavily glycosylated molecules with carbohydrate moieties contributing substantially to the levels of antigen detected in faeces. Application of the existing coproantigen tests in epidemiological and control programmes for Echinococcus and Taenia species infection has begun to contribute to an improved understanding of transmission and of surveillance of these important zoonotic cestodes.

    Serological diagnosis of alveolar echinococcosis (AE) is a key element for efficient patient treatment management. A rapid immunochromatography test kit (ICT) using the recombinant Em18 antigen (rEm18) was recently developed. The aim of our study was to assess this test on a panel of sera from French patients with alveolar echinococcosis and control patients. In a blind test, a total of 112 serum samples were tested including samples of AE (n = 30), cystic echinococcosis [CE] (n = 15), and polycystic echinococcosis [PE] (n = 1). For the comparison, 66 sera from patients with hepatocarcinoma, fascioliasis, toxocariasis, Caroli's disease, or autoimmune chronic active hepatitis were used. The diagnostic test sets we used were the rEm18-ICT and two validated ELISAs with rEm18 and Em2-Em18 antigens, respectively. For the ICT, 27/30 sera from AE patients, 4/15 sera from CE patients and the PE patient serum were positive. One serum from the control panel (toxocariasis) was positive for the ICT. The rEm18-ICT sensitivity (90.0%) and specificity (92.7%) for detection of Em18-specific antibodies confirmed it as a relevant tool for AE diagnosis. The rEm18-ELISA had a sensitivity of 86.7% and specificity of 91.5%, and the Em2-Em18-ELISA had a sensitivity of 96.7% and specificity of 87.8%. However, when AE patient sera are recorded as weak in intensity with the ICT, we recommend a double reading and use of a reference sample if the ICT is used for patient follow-up. © J.

    Full Text Available Introduction: The pathogen of multivisceral echinococcosis is the same agent as for single-organ echinococcosis: Echinococcus granulosus.According to the consensus of experts under the aegis of the WHO-IWGE - WHO-Informal Working Group on Echinococcosis options of treatment should be: (1 percutaneous treatment, (2 surgery, (3 anti-infective drug treatment or (4 watch and waitapproach or combinations thereof. Case report: The presented case was a seven-year-old Caucasian boy, a permanent resident of rural region near Tuzla, Bosnia and Herzegovina, who had a history of asymptomatic giant liver and small lung hydatid cyst (multivisceral echinococcosis. We consider that the patient was in the phase of secondary hydatidosis even before undergoing the first treatment PAIR method of liver and continued with adjunctive chemotherapy. Two weeks after discharge, during the adjunctive chemotherapy he had one of possible complication where pre-existed smal lung hydatid cyst gotinflamed and performed an abscess massand potential septic risk, which required surgical and antibiotic treatment. Surgery and early postoperative course were normal and the patient was discharged with recommendation to continue with previously started adjunctive chemotherapy (Albendazol according to treatment protocol. Conclusion: Most infected persons are asymptomatic and clinical manifestations vary according to the anatomic location of the cyst, so we want to indicate the importance of routine ultrasound screening of preschool children, and eventually X ray chest scan.This case report highlights the necessity of caution with choosing appropriate treatment, even though size of cyst can be irrelevant to take surgical treatment in first line instead of medical therapy.

    Purpose: To evaluate the CT findings of skeletal cystic echinococcosis. Material and Methods: CT findings of 7 patients with pathologically confirmed skeletal cystic echinococcosis were evaluated. Results: There were 4 men and 3 women, aged 36-75 years. Hydatid cysts were located in the spine (n=2), a rib (n=3), the pelvis and a vertebra (n=1), the pelvis and the left femur (n=1). The size of the lesions varied from 1 cm to 15 cm. CT showed well defined, single or multiple cystic lesions with no contrast enhancement, no calcification, no daughter cysts, and no germinal membrane detachment. The cystic lesion had a honeycomb appearance in 2 cases, there was pathologic fracture in 2 cases, bone expansion in 5 cases, cortical thinning in 6 cases, cortical destruction in 6 cases, bone sclerosis in 1 case, and soft tissue extension in 6 cases. Conclusion: Preoperative differential diagnosis of skeletal cystic lesions should include cystic echinococcosis, especially in endemic areas, since this diagnosis may easily be missed unless kept in mind.

    Purpose: To determine and compare the imaging features of hepatic alveolar Echinococcosis using color Doppler US, CT, and MRI. Material and Methods: Abdominal CT and MRI with and without contrast agents and color Doppler US were performed on seven patients with hepatic alveolar Echinococcosis. The lesions were evaluated for location, features of echogenicity, intensity and density, calcification, and vascular, hilar, and perihepatic involvement. The diagnosis was confirmed histopathologically in all patients. Results: Six patients had solitary lesions, and one displayed multiple lesions. The lesions were generally seen as heterogeneous and hyper- or hypoechoic when imaged with color Doppler US, hypodense with CT, and hypointense with MRI, in comparison with the liver parenchyma. Calcification, central necrosis, and small peripheral cysts were observed in six, seven, and four patients, respectively. Vascular flow or contrast enhancement was not observed in any of the cases. A look at the respective advantages of each method reveals that calcification was best rendered visible via CT, small peripheral cysts with T2-weighted MRI, central necrosis with CT and MRI, and perihepatic invasion with multiplanar MRI. Vascular involvement was revealed by all methods. Conclusion: Color Doppler US, CT, and MR imaging function extremely well as complementary methods in the diagnosis of HAE. Color Doppler US should be performed in these patients owing to its ability to efficiently detect the disease. Knowledge of imaging characteristics makes it possible to radiologically ascertain an early diagnosis

    Full Text Available Cystic echinococcosis (CE is caused by the tapeworm, Echinococcus granulosus. The tapeworms resides in the small intestines of canids and the lifecycle involves both intermediate and definitive hosts. Humans are accidental intermediate hosts. Cystic echinococcosis is an economically important infection constituting a threat to public health, and is considered an emerging disease around the world. There are at least 10 Echinococcus strain types (G1 – G10, each exhibiting diversity of morphology, development and host range. The epidemiology of CE is poorly understood in South Africa. A retrospective data analysis of the National Health Laboratory Service (NHLS laboratory information system on echinococcosis serology, microscopy and histopathology results in eight provinces (excluding KwaZula-Natal showed an overall positivity rate in submitted diagnostic samples of 17.0% (1056/6211, with the Eastern Cape (30.4%, North West (19.0% and Northern Cape (18.0% provinces showing highest rates. The data showed considerable variability between provinces. The review also showed that most proven cases were negative on serology, implying that the actual number of patients could be underestimated. To our knowledge, no data exist about the prevalent strains of E. granulosus and this prospective study will attempt to fill that gap. The aim is to genotype strains causing the disease in South Africa. Two different polymerase chain reaction (PCR methods will be used to respectively target the 12S rRNA and nad 1 genes. To date, three samples have been genotyped as G1, G5 and G6; suggesting diversity of strains prevalent in the country, but more data is needed for a clearer picture.

    An attempt has been made to estimate the diagnostic importance of computerized tomography (CT) in cases of hepatic echinococcosis and alveococcosis to outline the semiotics of these lesions and to establish an order of using CT in a general diagnostic complex. 73 patients at the age of 15-70 (49 with echinococcosis, 24-alveococcosis) have been supervised. The analysis of the results of clinical CT application in cases of parasitic hepatic lesions has shown that CT permits not only to reveal parasitic nodes up to 2 cm size in the liver and other organs but give also their topographoanatomic characteristic. By means of CT one can determine interrelations of parasitic formation with vessels and hepatic bileducts, vena cava inferior, other organs. One can judge at the same time on their compression and germination, remote echinococcosis residues, other complications

    Human cystic echinococcosis (CE) caused by infection with a larval stage of Echinococcus granulosus is a serious public health problem in Turkey. Echinococcosis is a zoonotic disease; dogs and livestock are important hosts in transmission. The aim of this study is to evaluate the rate of CE in Kayseri Rural Area, Central Anatolia, Turkey. At the present study, we planned to evaluate the rate of CE in Kayseri rural area in Central Anatolia between 2000 and 2002. We investigated 2,242 subjects using enzyme-linked immunosorbent assay (ELISA) and indirect fluorescence antibody (IFA), and we examined the seropositivity by using Western blotting (WB). The seropositivity rate was 2.7% by ELISA and IFA. We retested seropositive serum samples and 200 seronegative sera by WB. Seropositive serum samples were studied using abdominal ultrasound and chest x-ray to confirmed the presence of hydatid cyst and we found 10 (0.5%) different localized cysts. The results of our study indicate that Kayseri rural area has a high endemicity of human CE. (author)

    Taeniasis is one of the major food-borne parasitic zoonoses in Thailand. During the years 1957-1997, the prevalence was low in most parts of the country. Recent (2000-2005) country prevalence was lower than 1%. A high prevalence (5.9%) was found among 1450 villagers from 30 villages in the North, and among 1233 stool samples from 19 provinces in the Northeast (2.8%). Taenia saginata was the dominant species. Cysticercosis in Thailand is somewhat under-reported/recorded. During the period 1965-2005, diagnosis was based on techniques other than serodiagnosis, giving a total of cysticercosis cases of less than 500. However, an immunoblot technique using delipidized cyst antigen showed 314 positive cases out of 754 samples tested in 2000-2005. Reports of neurocysticercosis appeared more often than cutaneous cysticercosis. A total of 24 cases of echinococcosis, mostly hydatid cysts (only 2 cases of alveolar cysts), were recorded during 1936-2005. These records included 3 cases of foreigners seeking surgery in hospitals in Bangkok. Most Thai patients were migrant workers from the Middle East, and only a few cases were indigenous. The prevalence of cysticercosis and echinococcosis is increasing resulting from sensitive modern diagnostic tests. Taeniasis will persist in Thailand as the consumption of raw/half-cooked meat dishes is still a normal practice for Thai people.

    Echinococcosis is a neglected zoonotic disease, causing great morbidity and mortality due to the wide distribution of its endemic areas. China holds a high percentage in the global burden of both cystic and alveolar echinococcosis. A national survey conducted between 2012 and 2016 showed that an estimated 50 million people are at risk of contracting the disease in western China, of whom about 0.17 million are cases with echinococcosis.Despite this, research and development on echinococcosis in China is greatly inadequate compared to that in other countries. In this paper, we argue that there is a need for more research and work to be conducted in China on echinococcosis, including researching techniques in regards to diagnosis, treatment, and vaccination, and developing products through technical transformation and piloting strategies to control and even elimination.However, great opportunities exist for China to strengthen the research and development on this disease through initiatives such as Health China 2030, the Belt and Road Initiative, the China-Africa cooperation, as well as through further cooperation between China and the World Health Organization. All of these can bring us closer to controlling echinococcosis in China as well as in other countries. One element of crucial importance will be the training and development of professionals, which can be strengthened through international cooperation.

    Full Text Available The objective of the study was to examine the manifestations of the epidemic process of echinococcosis in the population of the Orenburg region. The incidence has been studied for the period of 1994–2012 according to various sources — the official data and the data of healthcare institutions of the region, in which the surgery for echinococcosis was carried out. A serological study of serum samples of persons who hadn’t echinococcosis previously, and genetic typing of echinococci by polymerase chain reaction were carried out. The difference in incidence rates has been obtained according to different sources. The incidence of echinococcosis among the population of the Orenburg region, according to the data of medical surgical facilities, significantly exceeded the notification rate and tended to increase. There were no significant differences between the incidence in adult and child population. The incidence of echinococcosis among individual groups and professions (breeders, shepherds, hunters and their families had no significant differences with the incidence of the rest adult population. In the districts of the region, where the incidence rate was significantly higher than average regional one, echinococcosis seroprevalence was also significantly higher than in the other territories. From humans and animals one strain of echinococcus — G1 (total, domestic sheep — has been isolated.

    Cystic echinococcosis (CE) constitutes an important public health problem in Peru. However, no studies have attempted to estimate the monetary and non-monetary impact of CE in Peruvian society. We used official and published sources of epidemiological and economic information to estimate direct and indirect costs associated with livestock production losses and human disease in addition to surgical CE-associated disability adjusted life years (DALYs) lost. The total estimated cost of human CE in Peru was U.S.$2,420,348 (95% CI:1,118,384-4,812,722) per year. Total estimated livestock-associated costs due to CE ranged from U.S.$196,681 (95% CI:141,641-251,629) if only direct losses (i.e., cattle and sheep liver destruction) were taken into consideration to U.S.$3,846,754 (95% CI:2,676,181-4,911,383) if additional production losses (liver condemnation, decreased carcass weight, wool losses, decreased milk production) were accounted for. An estimated 1,139 (95% CI: 861-1,489) DALYs were also lost due to surgical cases of CE. This preliminary and conservative assessment of the socio-economic impact of CE on Peru, which is based largely on official sources of information, very likely underestimates the true extent of the problem. Nevertheless, these estimates illustrate the negative economic impact of CE in Peru.

    Full Text Available Three cDNAs, termed EpC1, TPxEg and EgG5, were isolated by immunoscreening from an Echinococcus granulosus cDNA library. The recombinant phages exhibited strong reactivity with sera from humans with confirmed cystic echinococcosis (CE and with sera from mice infected with E. granulosus oncospheres. The cDNAs were subcloned into a pET vector, expressed as fusion proteins tagged with GST and affinity purified against the GST tag. Of the three recombinant proteins, EpC1 achieved the highest performance for serodiagnosis of CE in Western blot analysis using a panel of clinically defined human sera to initially address the sensitivity and specificity of the molecules. The protein yielded an overall sensitivity of 92.2% and specificity of 95.6%, levels unprecedented taking into account the large panel of 896 human sera that were tested. The strategy used may also prove suitable for improved immunodiagnosis of other parasitic infections.

    Full Text Available Cystic echinococcosis is endemic in Argentina. The standard pharmacological treatment for the disease is albendazole, but surgery is a common alternative. Even though primary infection occurs mainly in the pediatric population, the optimal therapeutic option in pediatrics is not clearly defined and few pediatric cohorts with cystic echinococcosis treated with albendazole have been described to date.To describe therapeutic response to albendazole in a cohort of pediatric patients with abdominal cystic echinococcosis.Patients (0-18 years old with abdominal cystic echinococcosis who were treated with albendazole between January 1998 and August 2013. Diagnosis of abdominal cystic echinococcosis was made by ultrasound. All patients received albendazole, 10-15 mg/kg/day. Epidemiological data, symptoms, number, location and outcome of the cysts, serology and treatment received were analyzed. The parameter used to assess treatment response was cyst changes evaluated by ultrasound follow up using the WHO-IWGE classification.A total of 28 patients (with 46 abdominal cysts were included in the cohort. Mean age at enrolment was 9.4 years and mean duration of follow-up, 23.8 months. All patients resided in rural areas and had had contact with dogs. The asymptomatic form of the disease was the most common presentation. All patients received albendazole (mean duration: 142.5 days, with low incidence of adverse events. Albendazole had a positive effect on most of the cysts. Surgery was performed in 13 patients.Treatment with albendazole for uncomplicated cystic echinococcosis cysts is safe and effective, and can potentially reduce the need for surgical intervention.

    Described are the characteristics of the polycystic larval cestodes found in an endemic area of echinococcosis in the Easter Plains of Colombia and the tissue reaction evoked in infected rodents. Of 848 free-ranging animals examined, polycystic hydatids were found in 44/93 Cuniculus paca and 1/369 Proechimys sp. None of 20 Dasyprocta fuliginosa examined was infected, but hunters provided a heart with hydatid cysts and information about two additional animals with infected livers. Recognition of an endemic area of polycystic echinococcosis provides a means to investigate the life cycle of the parasites and to study the histogenesis of the larval cestodes in susceptible laboratory animals.

    The prevalence of calcified cysts and the significance of calcification as a sign of cyst inactivity in cystic echinococcosis (CE) was evaluated. Seventy-eight patients (36 females, 42 males, mean age 40.8 {+-} 16.9 years) with CE, having a total of 137 abdominal cysts (116 hepatic, three splenic, one renal and 17 peritoneal cysts), were diagnosed and followed-up by ultrasound during and after albendazole treatment or as part of the watch-and-wait approach recording changes in the cyst wall and content. In 48 patients with 94 cysts, computed tomography (CT) imaging was additionally available and was correlated with ultrasound findings. Cyst wall calcification was classified into (1) ''sprinkled'', (2) ''eggshell-like'', and (3) ''circular''. Calcification of the cyst wall and/or cyst content was detected in 67 echinococcal cysts (48.9% of all cysts) in 39 patients (15 females, 24 males, mean age 40.8 {+-} 14.8 years). Of the total of 67 calcified cysts, only 23 were compatible with WHO type CE5, 18 with WHO type CE4. Judged by cyst content, the remaining 26 were of WHO type CE1, CE2 and CE3 (n = 1, n = 8, and n = 17, respectively). During a mean period of 34.3 months ({+-}21.3 months) the majority of cysts (n = 32) did not exhibit any change in cyst content and wall properties. Fourteen cysts showed signs of progressive involution, five cysts (all of WHO type CE3) of renewed activity defined by recurring fluid collection. In 16 cysts, no follow-up was available due to surgery or drop out. Calcification of the cyst is not restricted to the inactive WHO cyst types CE4 and CE5, but occurs in all stages and in up to 50% of cysts. The completeness and, most importantly, the stability of consolidation of cyst content over time predicts cyst inactivity more reliably. (orig.)

    Alveolar echinococcosis is a zoonotic parasitic disease causing a severe clinical condition and is known as the most deadly of all helminth infections. Moreover, this disease is also an increasing concern in Northern and Eastern Europe due to its spread in the wildlife animal host. An asymptomatic 70-year-old woman from south-western Hungary was diagnosed with multiple liver lesions. Imaging techniques (ultrasound, computed tomography and magnetic resonance imaging), serology (ELISA, indirect hemagglutination and Western blot), and conventional staining methods (hematoxylin-eosin and periodic acid-Schiff) were used for the detection of the disease. A histopathological re-evaluation of formalin-fixed paraffin block by immunohistochemical staining with the monoclonal antibody Em2G11 definitively confirmed the diagnosis of alveolar echinococcosis. To our knowledge, this is the first confirmed autochthonous case of human alveolar echinococcosis in Hungary. To what extent diagnostic difficulties may contribute to underestimate this zoonosis in Eastern Europe is unknown. Differential diagnosis with alveolar echinococcosis should be considered for patients with multiple, tumor-like cystic lesions of the liver, in countries where this parasite is emerging.

    Serial computed tomographic (CT) examinations of 37 rats infected with Echinococcus multilocularis were reviewed. In all cases the diagnosis was confirmed by pathologic examination. Small low density areas like hepatic cysts were visualized in the early stage. Honey comb appearance was characteristic in the late stage. Calcifications and central liqueation were also demonstrated. We must give specific attention to these findings to detect the alveolor echinococcal lesions of the liver. (author)

    Full Text Available Echinococcus granulosus sensu lato is a zoonotic agent with a life cycle consisting of definitive hosts (dogs and wild carnivores, and intermediate hosts (usually ungulates. Other animals and humans may accidentally ingest eggs and contract cystic echinococcosis, acting as aberrant hosts. A 3-year-old neutered female cat was brought to a veterinary practice in Sassari (Italy with abdominal distension. Ultrasound showed multiple intraperitoneal vesicles, which on laparotomy were found to be metacestodes of E. granulosus. Videos of the extraction of cysts are provided. Phylogenetic analysis based on a fragment of the cytochrome oxidase subunit 1 (cox1 mitochondrial gene identified the isolate as E. granulosus sensu stricto genotype G1, the most common genotype circulating in Europe and the Mediterranean basin. This is the first case report of cystic echinococcosis in domestic cats from Italy.

    The larval stage of Echinococcus granulosus causes cystic echinococcosis, a neglected infectious disease that constitutes a major public health problem in developing countries. Despite being under constant barrage by the immune system, E. granulosus modulates antiparasite immune responses and persists in the human hosts with detectable humoral and cellular responses against the parasite. In vitro and in vivo immunological approaches, together with molecular biology and immunoproteomic technologies, provided us exciting insights into the mechanisms involved in the initiation of E. granulosus infection and the consequent induction and regulation of the immune response. Although the last decade has clarified many aspects of host-parasite relationship in human cystic echinococcosis, establishing the full mechanisms that cause the disease requires more studies. Here, we review some of the recent developments and discuss new avenues in this evolving story of E. granulosus infection in man. PMID:22110535

    We review the imaging findings in seven children with alveolar echinococcosis of the liver. Calcification was seen on plain abdominal films in five of seven patients (66.6 %); the calcifications were small or coarse with irregular margins. Ultrasound was performed in four cases, identifying the lesions in all four as small calcifications with or without cysts. Computed tomography (CT) was performed in four cases and showed small calcifications, calcifications surrounding a cyst, or an aggregate of calcifications. Angiography was performed in all seven patients and showed changes of intrahepatic arterial stretching, overgrowth of small arteries, and a honeycomb pattern in the capillary phase. Venography revealed compression of the inferior vena cava in two patients. Serum screening together with ultrasonography and CT are useful for diagnostic imaging of alveolar echinococcosis. (orig.).

    The purpose of the present study was to evaluate the findings of MR imaging obtained in patients with Echinococcus multilocularis involving the liver. For 10 patients with alveolar echinococcosis of the liver, the MR findings were compared with the histopathologic findings after biopsy or surgery. Conventional T1-weighted spin echo, T2-weighted spin echo and T1-weighted spin echo after Gd-DTPA were employed. The signal from the lesions of alveolar liver echinococcosis on T1-weighted images was hypointense in 16 of 23 lesions (69.6%), hyperintense in 4 (17.4%), and isointense in 3 (13.0%). The signal from the lesions on T2-weighted images was hyperintense in 20 lesions (87.0%), hypointense in 2 (8.7%), and isointense in one (4.3%). On using Gd-DTPA, 7 of 21 lesions (33.3%) were observed with rim enhancement, and 14 lesions (66.7%) were non-enhanced. We describe our clinical experience together with the various findings of MR imaging as observed in the patients with alveolar echinococcosis of the liver. MR imaging excels in visualizing a low-intensity rim and small cystic foci, with liquefaction necrotic foci displaying a variety of signal intensities. After Gd-DTPA administration, the surrounding inflammatory granulomatous foci could be more clearly visualized. (author).

  16. The reconsideration of natural history of echinococcosis at Rebun Island.

    Minagawa, T

    1999-03-01

    It has been believed that the outbreak of echinococcosis at Rebun Island had ceased by 1970. The first patient was diagnosed in 1936 and 131 patients have been authorized as echinococcosis so far. The conference of measures against the outbreak had been organized in 1948 and started to eradicate Echinococcus multilocularis from the Island. Medical examination to detect the patients and the capture and autopsy of dogs and cats had been carried out hard till 1970. At that time, foxes imported from Simusiru Island in the middle Kuriles during the years 1924 to 1926 had already disappeared and it has seemed to be sure that stray dogs and cats might carry E. multilocularis and excrete infectious eggs in stead of foxes. Since we have had no real data concerning the natural history of patients with echinococcosis without any treatments, it can not be recognized the time of infection and the role of dogs or cats on the spread of echinococcosis at Rebun Island. From the new data, it is concluded that the active life cycle of E. multilocularis between foxes and vole might be closed by 1940, since the last patient infected with E. multilocularis was born in 1940 and died in 1945. Furthermore, it is estimated that more than 200 patients (3 to 4% of people at the island) might die from echinococcosis, because of the fact of the unusual increase of mortality of liver disorders and oldness observed during the years of 1940 to 1960. 81 patients with the high possibility of echinococcosis detected from 1937 to 1963 can be added to 131 authorized patients. Surprisingly, it is noticed that the standard deviations of ages of death of 94 patients born in Meiji era (1880-1912) and 59 in Taisho and Showa eras (1912-1940) are 63.16 +/- 11.68, and 34.32 +/- 11.87, respectively. It means that both old and young people might be infected simultaneously but for the long period. There was no difference between the susceptibility of young and old men to E. multilocularis.

    Human alveolar echinococcosis (AE) is a severe hepatic disease caused by Echinococcus multilocularis. In France, the definitive and intermediate hosts of E. multilocularis (foxes and rodents, respectively) have a broader geographical distribution than that of human AE. In this two-part study, we describe the link between AE incidence in France between 1982 and 2007 and climatic and landscape characteristics. National-level analysis demonstrated a dramatic increase in AE risk in areas with very cold winters and high annual rainfall levels. Notably, 52% (207/401) of cases resided in French communes (smallest French administrative level) with a mountain climate. The mountain climate communes displayed a 133-fold (95% CI: 95-191) increase in AE risk compared with communes in which the majority of the population resides. A case-control study performed in the most affected areas confirmed the link between AE risk and climatic factors. This arm of the study also revealed that populations residing in forest or pasture areas were at high risk of developing AE. We therefore hypothesised that snow-covered ground may facilitate predators to track their prey, thus increasing E. multilocularis biomass in foxes. Such climatic and landscape conditions could lead to an increased risk of developing AE among humans residing in nearby areas.

    The lack of knowledge regarding polycystic hydatid disease results in delayed or even incorrect diagnosis. The lack of systematic information regarding treatment also makes it difficult to assess the results and prognosis in patients with peritoneal and hepatic lesions caused by Echinococcus vogeli. Here we describe the clinical features of patients, propose a radiological classification protocol and describe a therapeutic option for the treatment of hydatid disease that previously had only been used for cases of cystic echinococcosis (Echinococcus granulosus). A prospective cohort study was initiated in 1999 and by 2009 the study included 60 patients. These patients were classified according to the PNM classification (parasite lesion, neighbouring organ invasion and metastases) and placed in one of three therapeutic modalities: (i) chemotherapy with albendazole at a dose of 10 mg/kg/day, (ii) surgical removal of cysts or (iii) percutaneous puncture of the cysts via puncture, aspiration, injection and re-aspiration (PAIR). The results were stratified according to therapeutic outcome: "cure", "clinical improvement", "no improvement", "death" or "no information". The PNM classification was useful in indicating the appropriate therapy in cases of polycystic hydatid disease. In conclusion, surgical therapy produced the best clinical results of all the therapies studied based on "cure" and "clinical improvement" outcomes. The use of PAIR for treatment requires additional study. PMID:23903966

    Full Text Available Cystic echinococcosis (CE is a widespread chronic endemic helminthic disease caused by infection with metacestodes of the tapeworm Echinococcus granulosus. CE affects humans and has a worldwide prevalence of approximately six million. In this review, we discuss current findings in diagnosis and clinical management of CE and new concepts relating to E. granulosus molecules that directly modulate the host immune responses favouring a strong anti-inflammatory response and perpetuating parasite survival in the host. New insights into the molecular biology of E. granulosus will improve considerably our knowledge of the disease and will provide new potential therapeutic applications to treat or prevent inflammatory immune-mediated disease.

  20. Treatment of echinococcosis: albendazole and mebendazole – what else?

    Full Text Available The search for novel therapeutic options to cure alveolar echinococcosis (AE, due to the metacestode of Echinococcus multilocularis, is ongoing, and these developments could also have a profound impact on the treatment of cystic echinococcosis (CE, caused by the closely related Echinococcus granulosus s.l. Several options are being explored. A viable strategy for the identification of novel chemotherapeutically valuable compounds includes whole-organism drug screening, employing large-scale in vitro metacestode cultures and, upon identification of promising compounds, verification of drug efficacy in small laboratory animals. Clearly, the current focus is targeted towards broad-spectrum anti-parasitic or anti-cancer drugs and compound classes that are already marketed, or that are in development for other applications. The availability of comprehensive Echinococcus genome information and gene expression data, as well as significant progress on the molecular level, has now opened the door for a more targeted drug discovery approach, which allows exploitation of defined pathways and enzymes that are essential for the parasite. In addition, current in vitro and in vivo models that are used to assess drug efficacy should be optimized and complemented by methods that give more detailed information on the host-parasite interactions that occur during drug treatments. The key to success is to identify, target and exploit those parasite molecules that orchestrate activities essential to parasite survival.

    Echinococcosis is a rare but endemic condition in people in Canada, caused by a zoonotic cestode for which the source of human infection is ingestion of parasite eggs shed by canids. The objectives of this study were to identify risk factors associated with infection and to measure the cost-utility of introducing an echinococcosis prevention program in a rural area. We analyzed human case reports submitted to the Canadian Institutes for Health Information between 2002 and 2011. Over this 10 year period, there were 48 cases associated with E. granulosus/E. canadensis, 16 with E. multilocularis, and 251 cases of echinococcosis for which species was not identified (total 315 cases). Nationally, annual incidence of echinococcosis was 0.14 cases per 100 000 people, which is likely an underestimate due to under-diagnosis and under-reporting. Risk factors for echinococcosis included female gender, age (>65 years), and residing in one of the northern territories (Nunavut, Yukon, or Northwest Territories). The average cost of treating a case of cystic echinococcosis in Canada was $8,842 CAD. Cost-utility analysis revealed that dosing dogs with praziquantel (a cestocide) at six week intervals to control cystic echinococcosis is not currently cost-effective at a threshold of $20,000-100,000 per Quality Adjusted Life Year (QALY) gained, even in a health region with the highest incidence rate in Canada ($666,978 -755,051 per QALY gained). However, threshold analysis demonstrated that the program may become cost-saving at an echinococcosis incidence of 13-85 cases per 100,000 people and therefore, even one additional CE case in a community of 9000 people could result in the monetary benefits of the program outweighing costs.

    Alveolar echinococcosis is a rare parasitic disease caused by Echinococcus multicularis and most commonly involves the liver. Early diagnosis and accurate evaluation of the effect of the treatment are essential to improve the prognosis of patients with alveolar echinococcosis of the liver (AEL). The aim of this study was to demonstrate the characteristic imaging of AEL by contrast-enhanced Dynamic Flow (CE-DF) employing a wide-band Doppler technique for the diagnosis and the accurate evaluation of the effect of the treatment. Four patients with five AEL lesions before treatment or during medication were examined by CE-DF. All of the five AEL lesions examined by CE-DF revealed a defect with an irregular and distinct margin like a worm-eaten defect appearance, which was never observed on other hepatic lesions, in liver perfusion image during post-vascular phase. In addition, CE-DF made it possible to measure the size of AEL lesions accurately because the margin was detected distinctly. These data suggest that CE-DF is clinically useful for the diagnosis of AEL and the evaluation of the effect of the treatment.

  4. Imaging techniques in the diagnosis of liver echinococcosis

    Liver echinococcosis, the most frequently occuring form of parasitosis, is caused by the following two types of tapeworm: echinococcus granulosus and echinococcus multilocularis. Both types are to be found in Austria, the latter even being endemic. Imaging techniques such as computed tomography and sonography enable the diagnosis to be made easily, quickly and accurately, although the number of conditions to be considered in the differential diagnosis is considerable. A comparison of the two methods in 32 patients, 25 with echinococcus multilocularis and 7 with echinococcus granulosus demonstrates that ultrasound is slightly inferior to computed tomography. However, ultrasound should be the primary method of investigation and is of great importance in followup, whilst computed tomography is necessary pre-operatively to assess the extrahepatic involvement.

    A 23-years old man, complaining of two weeks febrile period, general weakness, easy fatigue, breathlessness and lost of weight was admitted. Hepatomegaly, ascite, leg edema were observed. Abdominal computed tomography revealed a great number of hydatid cysts in the liver, spleen and peritoneum. The patient was treated with Albendazole, given at a dose of 10 mg/kg/day for six months. After one and half month of therapy the clinical status of the patient considerably improved, US and Computed tomography examination showed a decrease in size of the larger cysts, changes in cyst structure and disappearance of the smaller cysts. One and half year later almost ail cysts disappeared completely, the remaining represented some irregular spots with marked density. The results showed that Albendazole has rapid curative effect in patients with multiple abdominal echinococcosis. (authors)

    2008-05-01

    Full Text Available Abstract Background Cystic echinococcosis (CE is caused by the larva of tapeworm Echinococcus granulosus. Dogs and other canids are the primary definitive hosts for this parasite. CE may develop after accidental ingestion of tapeworm eggs, excreted with the feces of these animals. In the intestine, the larvae released from the eggs are nested in the liver, lungs or other organs of livestock as intermediate hosts and humans as aberrant hosts. The aim of this study was to examine serologically whether some of the patients in Slovenia, suspected of CE by imaging findings in the liver or lungs had been infected with the larva of Echinococcus granulosus. Methods Between January 1, 2002 and the end of December 2006, 1323 patients suspected of having echinococcosis were screened serologically by indirect haemagglutination assay (IHA. For confirmation and differentiation of Echinococcus spp. infection, the sera of IHA-positive patients were then retested by western blot (WB. Results Out of 127 IHA-positive sera, 34 sera were confirmed by WB and considered specific for CE. Of 34 sera of CE-positive patients sera, 32 corresponded to the characteristic imaging findings of a liver cysts and 2 to those of lung cysts. The mean age of CE-positive patients was 58.3 years. No significant differences were found between the CE-positive patients in regard to their sex. Conclusion In the study, it was found out that CE was mostly spread in the same area of Slovenia as in the past, but its prevalence decreased from 4.8 per 105 inhabitants in the period 1956–1968 to 1.7 per 105 inhabitants in the period 2002–2006. In spite of the decreased prevalence of CE in the last years, it is suggested that clinicians and public health authorities, especially in the eastern parts of Slovenia where the most CE patients come from, should pay greater attention to this disease in the future.

    Echinococcosis is a serious parasitic disease caused by Echinococcus tapeworms. Protoscoleces are sometimes released during surgical treatment for hydatid cysts, causing the recurrence of echinococcosis. Protoscoleces may be susceptible to radiation therapy. In this study Echinococcus protoscoleces were cultured in vitro and then divided into four different γ-ray irradiation dose groups (10 Gy, 20 Gy, 40 Gy, and 80 Gy) and a blank group. The protoscoleces were then implanted into the abdominal cavity of mice. Four months later, we observed that the incidence and weight of cysts declined with the increase of irradiation dose. γ-ray irradiation can suppress the generation of Echinococcus originated from protoscolex, the reason of which is due to the damaging to the structure of Echinococcus. Irradiation may prevent echinococcosis recurrence after surgical removal of hydatid cysts.

    Medical imaging and laboratory parameters permit a reliable detection and differentiation of cases of echinococcosis. Computerized tomography is a particularly valuable diagnostic tool here. In cases of liver infestation the resulting calcified foci are less readily revealed by magnetic resonance imaging than by CT, even though the former method has its merits in the diagnosis of concomitant vascular changes. If E. cysticus has invaded the lungs, the X-rays will show a sharply delineated round-to-oval cyst of uniform density, preferably in the lower and central compartments of that organ. In 1-4% of all organ infestations with E. cysticus it is the bone that has been parasitically invaded. In those cases, X-ray pictures of the osseous tissue show a light patch of a cyst-like appearance. Computerized tomography and nmr imaging are also able to visualize any soft tissue invasion beyond the limits of the diseased bony structures. Magnetic resonance imaging is the most sensitive method to detect bone marrow infestation. (orig./MG)

    We aim to determine the efficiency of CT in identification of cystic echinococcosis in sheep. Fifty-three sheep with liver cysts confirmed by ultrasonography were subject to CT scan to evaluate the number, size, and type of the cysts in liver and lung, confirmed using necropsy. The correlation of numbers between liver cysts and lung cysts was calculated using Pearson analysis. Necropsy indicated a 98% consensus on size, location, number, and activity compared with CT scan. The viable cysts were 53.1% and 50.6% in the liver and lung, respectively. Among the cysts in liver, 35.5%, 9.5%, 5.7%, 10.2%, and 39.1% were Types CE1, CE2, CE3, CE4, and CE5, respectively. The cysts in the lungs, 17.4%, 26.9%, 12.1%, 11.6%, and 32.1%, were Types CE1, CE2, CE3, CE4, and CE5, respectively. A significant correlation was noticed between the number of cysts in liver and those in lung ( R = 0.770, P < 0.001). CT scan is a suitable tool in determining the size and type of cystic hydatid cysts in both liver and lung of sheep. A significant correlation was noticed between the numbers in liver and lung, indicating that lung infection was likely due to the expansion of liver cyst burden pressure.

    2017-08-01

    Full Text Available ABSTRACT Cystic echinococcosis (CE or hydatidosis, a parasitic zoonosis caused by a cestode of the family Taeniidae, species Echinococcus granulosus, is endemic in Argentina, Chile, Peru, Uruguay, and southern Brazil. This report presents CE figures for these five countries in 2009 – 2014 and proposes indicators to measure national control programs. Nearly 5 000 new CE cases were diagnosed annually in the five countries during the study period. The average case fatality rate was 2.9%, which suggests that CE led to approximately 880 deaths in these countries during the 6-year period. CE cases that required secondary or tertiary health care had average hospital stays of 10.6 days, causing a significant burden to health systems. The proportion of new cases (15% in children less than 15 years of age suggests ongoing transmission. Despite figures showing that CE is not under control in South America, the long-standing implementation of national and local control programs in three of the five countries has achieved reductions in some of the indicators. The Regional Initiative for the Control of CE, which includes the five countries and provides a framework for networking and collaboration, must intensify its efforts.

    PurposeCystic echinococcosis (CE) in the spleen is a rare disease even in endemic regions. The aim of this study was to examine the efficacy of percutaneous treatment for splenic CE.Materials and MethodsTwelve patients (four men, eight women) with splenic CE were included in this study. For percutaneous treatment, CE1 and CE3A splenic hydatid cysts were treated with either the PAIR (puncture, aspiration, injection, respiration) technique or the catheterization technique.ResultsEight of the hydatid cysts were treated with the PAIR technique and four were treated with catheterization. The volume of all cysts decreased significantly during the follow-up period. No complication occurred in seven of 12 patients. Abscess developed in four patients. Two patients underwent splenectomy due to cavity infection developed after percutaneous treatment, while the spleen was preserved in 10 of 12 patients. Total hospital stay was between 1 and 18 days. Hospital stay was longer and the rate of infection was higher in the catheterization group. Follow-up period was 5–117 months (mean, 44.8 months), with no recurrence observed.ConclusionThe advantages of the percutaneous treatment are its minimal invasive nature, short hospitalization duration, and its ability to preserve splenic tissue and function. As the catheterization technique is associated with higher abscess risk, we suggest that the PAIR procedure should be the first percutaneous treatment option for splenic CE.

Registered 141 cases of echinococcosis in humans, incl. In children — 22 cases (15,6%. Among all the sick children, echinococcosis was more often reported in school-age persons — 90,9%. From the preschool age group, echinococcosis was recorded in two (9,1% unorganized children aged 5 and 6 years. The main complaints in the majority of invasive children were pain and a feeling of heaviness in the right hypochondrium — 40,9%, periodically arising cramping pain in the area of localization of the parasite — 31,8%. In rare cases, complaints of weakness and a feeling of bursting at the site of echinococcal cyst localization were noted — 4,5% each. A part of patients — 18,2% of the complaints were absent. When diagnosing, both laboratory and instrumental diagnostic methods were used. In most cases — 90,9%, the diagnosis of echinococcosis was confirmed by the enzyme immunoassay (ELISA method. Thus, recently in the territory of the Astrakhan region there has been an increase in the number of cases of human infection with echinococcus, incl. аnd children of school age. The parasite is located, as a rule, in the liver and lung. The disease was susceptible to those who had a history of permanent contact with non-undelminthic dogs. In the diagnosis of echinococcosis, the main role is played by the complex methods of ELISA, CT, ultrasound, x-ray and histological methods.

    Cystic echinococcosis is caused by the larval stage of the dog tapeworm, Echinococcus granulosus . The disease is recognized as one of the world's major zoonoses affecting human beings and domestic animals apart from its economic and public health importance. Development of the cysts in the intermediate host such as buffaloes occurs in the lungs, liver and other organs. In this study, detection of circulating antigen in the diagnosis of cystic echinococcosis in buffaloes was done using enzyme linked immunosorbent assay and Dot-Enzyme immunoassay (Dot-EIA). The sensitivity and specificity were determined as 89 and 92 % respectively, whereas those of Dot-EIA were determined as 94 and 96 %.

    Full Text Available BACKGROUND: Cystic echinococcosis (CE can affect the heart and the vena cava but few cases are reported. METHODS: A retrospective case series of 11 patients with cardiac and/or endovascular CE, followed-up over a period of 15 years (1995-2009 is reported. RESULTS: Main clinical manifestations included thoracic pain or dyspnea, although 2 patients were asymptomatic. Cysts were located mostly in the right atrium and inferior vena cava. Nine patients were previously diagnosed with disseminated CE. Echocardiography was the diagnostic method of choice, although serology, electrocardiogram, chest X-ray, computed tomography/magnetic resonance imaging and histology aided with diagnosis and follow-up. Nine patients underwent cardiac surgery and nine received long-term antiparasitic treatment for a median duration of 25 months (range 4-93 months. One patient died intra-operatively due to cyst rupture and endovascular dissemination. Two patients died 10 and 14 years after diagnosis, due to pulmonary embolism (PE and cardiac failure, respectively. One patient was lost to follow-up. Patients who had cardiac involvement exclusively did not have complications after surgery and were considered cured. There was only one recurrence requiring a second operation. Patients with vena cava involvement developed PEs and presented multiple complications. CONCLUSIONS: Cardiovascular CE is associated with a high risk of potentially lethal complications. Clinical manifestations and complications vary according to cyst location. Isolated cardiac CE may be cured after surgery, while endovascular extracardiac involvement is associated with severe chronic complications. CE should be included in the differential diagnosis of cardiovascular disease in patients from endemic areas.

  3. Anthelminthic activity of glibenclamide on secondary cystic echinococcosis in mice.

    2017-11-01

    Full Text Available Cystic echinococcosis (CE is a worldwide parasitic zoonosis caused by the larval stage of Echinococcus granulosus. Current chemotherapy against this disease is based on the administration of benzimidazoles (BZMs. However, BZM treatment has a low cure rate and causes several side effects. Therefore, new treatment options are needed. The antidiabetic drug glibenclamide (Glb is a second-generation sulfonylurea receptor inhibitor that has been shown to be active against protozoan parasites. Hence, we assessed the in vitro and in vivo pharmacological effects of Glb against the larval stage of E. granulosus. The in vitro activity was concentration dependent on both protoscoleces and metacestodes. Moreover, Glb combined with the minimum effective concentration of albendazole sulfoxide (ABZSO was demonstrated to have a greater effect on metacestodes in comparison with each drug alone. Likewise, there was a reduction in the cyst weight after oral administration of Glb to infected mice (5 mg/kg of body weight administered daily for a period of 8 weeks. However, in contrast to in vitro assays, no differences in effectiveness were found between Glb + albendazole (ABZ combined treatment and Glb monotherapy. Our results also revealed mitochondrial membrane depolarization and an increase in intracellular Ca2+ levels in Glb-treated protoscoleces. In addition, the intracystic drug accumulation and our bioinformatic analysis using the available E. granulosus genome suggest the presence of genes encoding sulfonylurea transporters in the parasite. Our data clearly demonstrated an anti-echinococcal effect of Glb on E. granulosus larval stage. Further studies are needed in order to thoroughly investigate the mechanism involved in the therapeutic response of the parasite to this sulfonylurea.

    Background Alveolar echinococcosis (AE) caused by Echinococcus multilocularis infections is a dangerous old disease in the Northern Hemisphere. The aim of the paper was to collect and analyze data on human AE in Poland in the last two decades. Methodology/Principal Findings The sources of data were both the cases officially registered and detected by an active field and laboratory surveillance. The cases were verified by clinical, epidemiological, and laboratory criteria. Altogether 121 human cases of AE were detected. Among these 83 (68,6%) cases were classified as confirmed, 16 as probable and 22 as possible. During the two decades a continuous increase in detection rate was noticed. The cases were 6–82 years old at the time of diagnosis (mean - 47.7 years). Sex ratio M/F was 0.86/1.0. The AE was fatal in 23 (19%) patients (mean age at death - 54.1 years). Family agglomeration of AE was found in 4 foci, involving 9 patients. Seventy six of the cases were diagnosed in an advanced stage of disease. In all cases the liver was the primary location of AE. In 30 (24.8%) patients a spread to other organs was observed. Ninety four of the patients were treated with albendazole. In 73 (60%) patients a surgical operation was performed, including 15 liver transplantations. Conclusions/Significance The studies confirmed that AE is an emerging disease in Poland, which is the fourth country in Europe with over 120 cases detected. The results also indicate the need of a wider national programme for implementation of screening in the highest AE risk areas (north-eastern Poland) with an effort to increase the public awareness of the possibility of contracting E. multilocularis, and above all, training of the primary care physicians in the recognition of the risk of AE to allow for an early detection of this dangerous disease.

    To predict the monthly reported echinococcosis cases in China with the autoregressive integrated moving average (ARIMA) model, so as to provide a reference for prevention and control of echinococcosis. SPSS 24.0 software was used to construct the ARIMA models based on the monthly reported echinococcosis cases of time series from 2007 to 2015 and 2007 to 2014, respectively, and the accuracies of the two ARIMA models were compared. The model based on the data of the monthly reported cases of echinococcosis in China from 2007 to 2015 was ARIMA (1, 0, 0) (1, 1, 0) 12 , the relative error among reported cases and predicted cases was -13.97%, AR (1) = 0.367 ( t = 3.816, P ARIMA (1, 0, 0) (1, 0, 1) 12 , the relative error among reported cases and predicted cases was 0.56%, AR (1) = 0.413 ( t = 4.244, P ARIMA models as for the same infectious diseases. It is needed to be further verified that the more data are accumulated, the shorter time of predication is, and the smaller the average of the relative error is. The establishment and prediction of an ARIMA model is a dynamic process that needs to be adjusted and optimized continuously according to the accumulated data, meantime, we should give full consideration to the intensity of the work related to infectious diseases reported (such as disease census and special investigation).

    Echinococcosis, which can seriously harm human health and animal husbandry production, has become an endemic in the Xinjiang Uygur Autonomous Region of China. In order to explore an effective human Echinococcosis forecasting model in Xinjiang, three grey models, namely, the traditional grey GM(1,1) model, the Grey-Periodic Extensional Combinatorial Model (PECGM(1,1)), and the Modified Grey Model using Fourier Series (FGM(1,1)), in addition to a multiplicative seasonal ARIMA(1,0,1)(1,1,0)₄ model, are applied in this study for short-term predictions. The accuracy of the different grey models is also investigated. The simulation results show that the FGM(1,1) model has a higher performance ability, not only for model fitting, but also for forecasting. Furthermore, considering the stability and the modeling precision in the long run, a dynamic epidemic prediction model based on the transmission mechanism of Echinococcosis is also established for long-term predictions. Results demonstrate that the dynamic epidemic prediction model is capable of identifying the future tendency. The number of human Echinococcosis cases will increase steadily over the next 25 years, reaching a peak of about 1250 cases, before eventually witnessing a slow decline, until it finally ends.

    This article focuses on understanding epidemiological features of alveolar echinococcosis and discussing its prevention and control, especially from a viewpoint of the ecosystem and risk management. Publications on alveolar echinococcosis throughout the world were systematically reviewed with special reference to ecology, epidemiology and countermeasures. Alveolar echinococcosis, caused by accidental infection with larva of the parasite Echinococcus multilocularis is fatal to humans unless diagnosed at an early stage. No effective control measures have been identified so far because it is difficult to fully understand the ecology of the parasite and its intermediate and definitive hosts. It is also not easy to determine the precise infection route to humans mainly because of the long latent period. In Hokkaido, infection rates among red foxes have recently risen even in low endemic districts. Not only stray and domestic dogs but also some pigs in Hokkaido have been found to be infected. While the number of reported human cases is still small, around 10 cases per year, local residents seem to be threatened with the risk of infection. We predict that the incidence of alveolar echinococcosis among humans in Japan will increase in the near future if no effective preventive measures are conducted. In addition, Echinococcus multilocularis infection has the potential to affect the economy of Hokkaido because of its impact on the agricultural and tourist industries. Well-designed epidemiological surveys are therefore urgently required, in the context of ecosystem and risk management prior to large outbreaks. International collaboration is also desired.

    Full Text Available Human echinococcosis is a neglected zoonosis caused by parasites of the genus Echinococcus. The most frequent clinical forms of echinococcosis, cystic echinococcosis (CE and alveolar echinococcosis (AE, are responsible for a substantial health and economic burden, particularly to low-income societies. Quantitative epidemiology can provide important information to improve the understanding of parasite transmission and hence is an important part of efforts to control this disease. The purpose of this review is to give an insight on factors associated with echinococcosis in animal hosts by summarising significant results reported from epidemiological studies identified through a systematic search.The systematic search was conducted mainly in electronic databases but a few additional records were obtained from other sources. Retrieved entries were examined in order to identify available peer-reviewed epidemiological studies that found significant risk factors for infection using associative statistical methods. One hundred studies met the eligibility criteria and were suitable for data extraction. Epidemiological factors associated with increased risk of E. granulosus infection in dogs included feeding with raw viscera, possibility of scavenging dead animals, lack of anthelmintic treatment and owners' poor health education and indicators of poverty. Key factors associated with E. granulosus infection in intermediate hosts were related to the hosts' age and the intensity of environmental contamination with parasite eggs. E. multilocularis transmission dynamics in animal hosts depended on the interaction of several ecological factors, such as hosts' population densities, host-prey interactions, landscape characteristics, climate conditions and human-related activities.Results derived from epidemiological studies provide a better understanding of the behavioural, biological and ecological factors involved in the transmission of this parasite and hence

    Alveolar echinococcosis (AE) is life-threatening and reports on surgical procedures and results are rare, but essential. Longitudinal surveillance and long-term follow-up of patients surgically treated for AE during the periods 1982-1999 (group A) and 2000-2006 (group B). University hospital within an endemic area. The median (min-max) follow-up period was 141 (5-417) months. Forty-eight surgical procedures were performed in 36 patients with AE: 63% were partial resections of the liver (additional extrahepatic resection in ten of them), 17% just extrahepatic resections, 10% biliodigestive anastomosis, and 10% exploratory laparotomies. Seventy-five percent of the operations were first-time procedures, 25% done due to a relapse. Forty-two percent of the operations were estimated to be curative (R0), whereas 58% were palliative (R1, R2). All patients had additional medical treatment and periodical follow-up. Two out of 18 (11%) patients, estimated to have had curative surgery, developed a relapse 42 and 54 months later. R0-resection rates depended on the primary, neighboring, metastasis stage of AE (S1, 100%; S2, 100%; S3a, 33%; S3b, 27%; S4, 11%). During the period 2000-2006 elective radical surgery for AE was done only if a safe distance of at least 2 cm was attainable. This concept was associated with an increased R0-resection rate of 87% for group B compared to 24% for group A. Operative procedures done to control complicated courses of AE (jaundice, cholangitis, vascular compression, bacterial superinfection) have not been curative (R2) in 82% because the disease had spread into irresectable structures. Morbidity was 19%. All patients with curative resections are alive. Fifty-six percent of the patients with palliative treatment are alive as long as 14-237 months, 28% died from AE 164-338 months after diagnosis (late lethality), and 17% died due to others diseases 96-417 months after diagnosis of AE. One out of seven (14%) patients suffering from suppurative

    Objective: To investigate the characteristics of proton magnetic resonance spectroscopy ( 1 H MRS) in patients with cerebral alveolar echinococcosis (CAE). Methods: Thirteen patients with 33 lesions proven to be CAE histologically and clinically were examined by conventional MRI and 2D multi-voxel spectroscopy with a 3.0 T double gradient superconductivity magnetic resonance scanner. Concentrations of the metabolites containing N-acetyl-aspartic-acid (NAA), Choline (Cho), Creatine (Cr), lipids and lactic acid (Lip + Lac), myo-Inositol (mI) were detected and the value of Cho/Cr, NAA/Cr, (Lip + Lac)/Cr, mI/Cr were calculated. The values of Cho/Cr, NAA/Cr, (Lip + Lac)/Cr, mI/Cr were compared between the lesions and the contralateral normal brain parenchyma. Statistical analysis was performed using the Wilcoxon signed-rank test. Results: CAE 1 H MRS in the lesions was characterized by the decrease of Cho, NAA to varying degrees, and a visible lipid with or without lactate peak. Compared with the control group, the ratio of NAA/Cr was decreased markedly, whereas Cho/Cr, mI/Cr increased mildly and (Lip + Lac)/Cr increased markedly in the lesions. The medians and interquartile ranges of Cho/Cr, NAA/Cr, (Lip + Lac)/Cr and mI/Cr in the lesions were: 1.88 (1.24-2.23), 1.32 (1.07-1.58), 32.96 (24.59-47.30) and 0.91 (0.67-1.08), respectively. The medians and interquartile ranges of Cho/Cr, NAA/Cr, (Lip + Lac)/Cr and mI/Cr of control group were 0.84 (0.704-0.98), 2.00 (1.80-2.18), 0.90 (0.74-0.99) and 0.26 (0.18-0.31), respectively. There were statistically significant differences of the measures between the lesions and the control regions (Z=-5.932, -6.086, -6.946, -6.984, P<0.01). Conclusions: Multi-voxel 1 H MRS can reflect pathological characteristics of CAE. 1 H MRS provides metabolic information for diagnosis of CAE and may be a supplement to conventional magnetic resonance examination.

    Full Text Available Alveolar echinococcosis (AE is an endemic zoonosis in France due to the cestode Echinococcus multilocularis. The French National Reference Centre for Alveolar Echinococcosis (CNR-EA, connected to the FrancEchino network, is responsible for recording all AE cases diagnosed in France. Administrative, epidemiological and medical information on the French AE cases may currently be considered exhaustive only on the diagnosis time. To constitute a reference data set, an information system (IS was developed thanks to a relational database management system (MySQL language. The current data set will evolve towards a dynamic surveillance system, including follow-up data (e.g. imaging, serology and will be connected to environmental and parasitological data relative to E. multilocularis to better understand the pathogen transmission pathway. A particularly important goal is the possible interoperability of the IS with similar European and other databases abroad; this new IS could play a supporting role in the creation of new AE registries.

    In urban populations of South America, dogs with free access to public areas represent a public health concern. The primary consequence of roaming dogs on human health is the transmission of infectious and parasitic diseases mainly through feces contamination. The main diseases likely to be transmitted are hydatidosis or echinococcosis, larva migrans, and giardiasis. In Argentina, hydatidosis ranks among the most prevalent zoonosis. Although it is considered a rural disease, the circulation o...

  5. Human and canine echinococcosis infection in informal, unlicensed abattoirs in Lima, Peru.

    Directory of Open Access Journals (Sweden)

    Full Text Available Echinococcus granulosus infections are a major public health problem in livestock-raising regions around the world. The life cycle of this tapeworm is sustained between dogs (definitive host, canine echinococcosis, and herbivores (intermediary host, cystic hydatid disease. Humans may also develop cystic hydatid disease. Echinococcosis is endemic in rural areas of Peru; nevertheless, its presence or the extension of the problem in urban areas is basically unknown. Migration into Lima, an 8-million habitant's metropolis, creates peripheral areas where animals brought from endemic areas are slaughtered without veterinary supervision. We identified eight informal, unlicensed abattoirs in a peripheral district of Lima and performed a cross-sectional study in to assess the prevalence of canine echinococcosis, evaluated by coproELISA followed by PCR evaluation and arecoline purge. Eight of 22 dogs (36% were positive to coproELISA, and four (18% were confirmed to be infected with E. granulosus tapeworms either by PCR or direct observation (purge. Later evaluation of the human population living in these abattoirs using abdominal ultrasound, chest X-rays and serology, found 3 out of 32 (9.3% subjects with echinococcal cysts in the liver (two viable, one calcified, one of whom had also lung involvement and a strongly positive antibody response. Autochthonous transmission of E. granulosus is present in Lima. Informal, unlicensed abattoirs may be sources of infection to neighbouring people in this urban environment.

    The Xinjiang Uyghur Autonomous Region in northwest China is one of the world's most important foci for cystic echinococcosis. Domestic dogs are the main source for human infection, and previous studies in Xinjiang have found a canine Echinococcus spp. coproELISA prevalence of between 36% and 41%. In 2010 the Chinese National Echinococcosis Control Programme was implemented in Xinjiang, and includes regular dosing of domestic dogs with praziquantel. Six communities in Hobukesar County, northwest Xinjiang were assessed in relation to the impact of this control programme through dog necropsies, dog Echinococcus spp. coproantigen surveys based on Lot Quality Assurance Sampling (LQAS) and dog owner questionnaires. We found that 42.1% of necropsied dogs were infected with Echinococcus granulosus, and coproELISA prevalences were between 15% and 70% in the communities. Although approximately half of all dog owners reported dosing their dogs within the 12 months prior to sampling, coproELISA prevalence remained high. Regular praziquantel dosing of owned dogs in remote and semi-nomadic communities such as those in Hobukesar County is logistically very difficult and additional measures should be considered to reduce canine echinococcosis.

    We focused on the epidemiology of alveolar echinococcosis especially in Japan and discussed control measures to prevent an epidemic. No effective control measures against alveolar echinococcosis have been identified thus far because it is difficult to fully understand the ecology of the parasite and its hosts, i.e. the precise infection route to humans. In Hokkaido, Japan, infection rates among red foxes have recently risen even in low endemic districts. Infection seems to be spreading not only among wild foxes but also among domestic dogs. Despite only sporadic reports of human cases in Japan, we predict that the incidence of alveolar echinococcosis will increase in the near future if no effective preventive measures are put in place. An Echinococcus multilocularis epidemic would have the potential to affect the economy of Hokkaido, due to its impact on the agricultural and tourist industries. Well-designed epidemiological surveys are, therefore, urgently required prior to large outbreaks, based on understanding of the ecosystem around E. multilocularis.

    Objective: To evaluate the image features of lung echinococcosis under chemotherapy with liposome-entrapped albendazole. Methods: Sixteen patients with lung echinococcosis who took orally liposome-entrapped albendazole (10 mg/kg, Bid, 3 to 10 months) were examined by X-ray film, CT or MR before therapy and followed-up by those imaging studies after therapy. The morphological changes of the lesions as reflected on imaging findings were reviewed, with correlation of the clinic check-ups and laboratory tests, to judge effectiveness of the treatment. Results: Five cases were completely cured. The treatment was effective in 6 cases, partially effective in 4 and invalid in 1 case. The imaging findings included: cavity formation in 7 cases due to hydatid cyst degeneration and absorption of cyst liquid; reduction in lesion size in 6 cases; disappearance of lesion or decrease in lesion numbers in 2 cases; increase in lesion density and blurring of cyst wall in 6 cases duo to cyst consolidation; rupture, shrinkage, collapse of cyst inner membrane in 3 cases; calcification of the cyst wall or contents in 6 cases. Conclusions: It is shown that liposome-entrapped albendazole chemotherapy has curative effect for lung echinococcosis. Imaging examinations are effective for monitoring the evolution of the disease by depicting the morphologic-pathologic changes of the lesions. (authors)

In a large percentage, E. cysticus demonstrated typical cystic and expansive signs; atypical vessels were rarely seen. How the 'rim sign' develops is demonstrated. Usual signs of E. alveolaris are incomplete solid and necrotic space occupying lesions, as seen also in malignancy.

    Echinococcosis is a re-emerging zoonotic disease in Kyrgyzstan. In 2012, an echinococcosis control scheme was started that included dosing owned dogs in the Alay Valley, Kyrgyzstan with praziquantel. Control programmes require large investments of money and resources; as such it is important to evaluate how well these are meeting their targets. However, problems associated with echinococcosis control schemes include remoteness and semi-nomadic customs of affected communities, and lack of resources. These same problems apply to control scheme evaluations, and quick and easy assessment tools are highly desirable. Lot quality assurance sampling was used to assess the impact of approximately 2 years of echinococcosis control in the Alay valley. A pre-intervention coproELISA prevalence was established, and a 75% threshold for dosing compliance was set based on previous studies. Ten communities were visited in 2013 and 2014, with 18-21 dogs sampled per community, and questionnaires administered to dog owners. After 21 months of control efforts, 8/10 communities showed evidence of reaching the 75% praziquantel dosing target, although only 3/10 showed evidence of a reduction in coproELISA prevalence. This is understandable, since years of sustained control are required to effectively control echinococcosis, and efforts in the Alay valley should be and are being continued.

Antiparasitic treatment with albendazole remains the primary choice for the great majority of patients in this resource-poor remote area, though surgery is the most common approach for CE therapy that has the potential to remove cysts and lead to complete cure. The current prospective study aimed to assess the effectiveness of community based use of cyclic albendazole treatment in Tibetan CE cases, and concurrently monitor the changes of serum specific antibody levels during treatment.Ultrasonography was applied for diagnosis and follow-up of CE cases after cyclic albendazole treatment in Tibetan communities of Sichuan Province during 2006 to 2008, and serum specific IgG antibody levels against Echinococcus granulosus recombinant antigen B in ELISA was concurrently monitored in these cases. A total of 196 CE cases were identified by ultrasound, of which 37 (18.9% showed evidence of spontaneous healing/involution of hepatic cyst(s with CE4 or CE5 presentations. Of 49 enrolled CE cases for treatment follow-up, 32.7% (16 were considered to be cured based on B-ultrasound after 6 months to 30 months regular albendazole treatment, 49.0% (24 were improved, 14.3% (7 remained unchanged, and 4.1% (2 became aggravated. In general, patients with CE2 type cysts (daughter cysts present needed a longer treatment course for cure (26.4 months, compared to cases with CE1 (univesicular cysts (20.4 months or CE3 type (detached cyst membrane or partial degeneration of daughter cysts (9 months. In addition, the curative duration was longer in patients with large (>10 cm cysts (22.3 months, compared to cases with medium (5-10 cm cysts (17.3 months or patients with small (<5 cm cysts (6 months. At diagnosis, seven (53.8% of 13 cases with CE1 type

  7. Cystic echinococcosis in Spain: current situation and relevance for other endemic areas in Europe.

    Francisco A Rojo-Vazquez

    Full Text Available Cystic echinococcosis (CE remains an important health problem in many regions of the world, both where no control measures have been implemented, and where control programs have been incompletely successful with ensuing re-emergence of the disease. In Spain, official data on CE show an increase in the proportion of intermediate hosts with CE during the last few years, and autochthonous pediatric patients have been reported, a sign of active local transmission of disease. A similar picture emerges from data reported to the European Food Safety Authority by other European countries. Nevertheless, several crucial aspects related to CE that would help better understand and control the disease have not been tackled appropriately, in particular the emergence of infection in specific geographical areas. In this respect, while some data are missing, other data are conflicting because they come from different databases. We review the current situation of CE in Spain compared with areas in which similar problems in the CE field exist, and offer recommendations on how to overcome those limitations. Specifically, we believe that the introduction of national registries for CE with online data entry, following the example set by the European Registry for Alveolar Echinococcosis, would help streamline data collection on CE by eliminating the need for evaluating and integrating data from multiple regions, by avoiding duplication of data from patients who access several different health facilities over time, and by providing much needed clinical and epidemiological data that are currently accessible only to clinicians.

    Full Text Available Abstract Objective A commercial cysticercosis Western blot was evaluated for serological cross-reactivity of sera from patients with alveolar (AE and cystic echinococcosis (CE. Methods A total of 161 sera were examined, including 31 sera from AE-patients, 11 sera from CE-patients, 9 sera from patients with other parasitic diseases and 109 sera from patients with unrelated medical conditions. All AE-and CE-sera were also examined by the echinococcosis Western blot. Results More sera from patients with AE than with CE showed cross-reactivity in the form of ladder-like patterns ("Mikado aspect" and untypical bands at 6-8 kDa (71% and 77.4% versus 27.3% and 45.5%, respectively. In contrast, triplets of bands in the area above 50 kDa and between 24 and 39-42 kDa were more frequent in CE than in AE sera. The fuzzy band at 50-55 kDa typical for cysticercosis was absent in all AE and CE sera. Conclusions Atypical banding patterns in the cysticercosis Western blot should raise the suspicion of a metacestode infection different from Taenia solium, i.e. Echinococcus multilocularis or E. granulosus, especially when the Mikado aspect and an altered 6-8 kDa band is visible in the absence of a fuzzy 50-55 kDa band.

  9. Non-surgical and non-chemical attempts to treat echinococcosis: do they work?

    Tamarozzi Francesca

    2014-01-01

    Full Text Available Cystic echinococcosis (CE and alveolar echinococcosis (AE are chronic, complex and neglected diseases. Their treatment depends on a number of factors related to the lesion, setting and patient. We performed a literature review of curative or palliative non-surgical, non-chemical interventions in CE and AE. In CE, some of these techniques, like radiofrequency thermal ablation (RFA, were shelved after initial attempts, while others, such as High-Intensity Focused Ultrasound, appear promising but are still in a pre-clinical phase. In AE, RFA has never been tested, however, radiotherapy or heavy-ion therapies have been attempted in experimental models. Still, application to humans is questionable. In CE, although prospective clinical studies are still lacking, therapeutic, non-surgical drainage techniques, such as PAIR (puncture, aspiration, injection, re-aspiration and its derivatives, are now considered a useful option in selected cases. Finally, palliative, non-surgical drainage techniques such as US- or CT-guided percutaneous biliary drainage, centro-parasitic abscesses drainage, or vascular stenting were performed successfully. Recently, endoscopic retrograde cholangiopancreatography (ERCP-associated techniques have become increasingly used to manage biliary fistulas in CE and biliary obstructions in AE. Development of pre-clinical animal models would allow testing for AE techniques developed for other indications, e.g. cancer. Prospective trials are required to determine the best use of PAIR, and associated procedures, and the indications and techniques of palliative drainage.

    Echinococcosis is a zoonotic disease that is widely spread across Argentina and worldwide. It is acquired during childhood but it is more common during adulthood. The pediatric population accounts for 10-20% of all cases. This study included 47 children diagnosed with echinococcosis over a 20-year period. Their median age was 8 years old (range: 3-17); most patients had some epidemiological history, such as having lived or living in an endemic or rural area and/ or having dogs that are fed with viscera. Findings included 85% of single cysts in only one parenchyma. Cysts were most commonly located in the liver and lungs. Medical/surgical treatment was carried out in 45 patients (96%). Subsequent complications were observed in 13 patients (28%), which were more common in those with lung cysts. Three patients (6%) relapsed 1-24 months later and required a new surgery. No patient died as a result of the parasitic disease. Sociedad Argentina de Pediatría.

  11. Impact of Echinococcosis on Quality of Sheep Meat in the South Eastern Kazakhstan

    Directory of Open Access Journals (Sweden)

    Z. Valieva

    2014-03-01

    Full Text Available A survey of 2,123 slaughtered adult sheep in markets of the south-east Kazakhstan established that the average contamination of animals by Echinococcus granulosus is 9.1% with primary localization of cysts in livers and lungs. The histologic structure of the muscle tissue of infected sheep displayed destructive changes with a prevalence of granular dystrophy. The amount of protein, fat, calcium and energetical value of such meat considerably decreased. Besides in the muscle tissue of the animals infected with echinococcosis there was a substantial increase of humidity and amount of ash as well as qualitative and quantitative changes of the amino acids profile. Along with damage to the synthesis of proteins and sharp insufficiency of vitamins A, E, B1, and B2 there was a shift in a lipidic exchange that was expressed as a noticeable reduction in the level of monounsaturated and polyunsaturated fatty acids. The data support the conclusion that the meat from the sheep infected with echinococcosis is of inferior quality and quantity compared to that of healthy animals.

    During the period from March 2006 to July 2009 a total of 2040 slaughtered donkeys were examined for cystic echinococcosis (CE). CE prevalence in donkeys was 8.48% and the infection pressure (0.0088 infections per year) and infection rate (0.0448 cysts per year) appeared to be lower than those previously reported for cattle, sheep, dromedaries and goats in Tunisia. However, the number of cysts per infection was relatively high (5.07 cysts per infection). Among the 901 collected hydatid cysts the majority were located in the liver (89.9%), 10.09% in the lungs and 4.77% were fertile (43/901). The amplification of a fragment within the mitochondrial gene coding for cytochrome c oxidase subunit 1 (cox1) revealed that donkeys were infected with both Echinococcus equinus (horse strain, G4 genotype) and Echinococcus granulosus (sheep strain, G1 genotype). E. granulosus G1 developed into fertile cysts (15,112 protoscoleces/ml) with a protoscoleces viability of 65.78%.

    Cystic echinococcosis is a chronic, complex, and still neglected disease. Although albendazole has demonstrated efficacy, only about one-third of patients experience complete remission or cure and 30-50% of treated patients develop some evidence of a therapeutic response. Different strategies have been developed in order to improve the albendazole water solubility and dissolution rate. The aim of the current work was to investigate the chemoprophylactic and clinical efficacy of an albendazole:poloxamer 188 solid dispersion formulation on mice infected with Echinococcus granulosus metacestodes. Albendazole formulated as solid dispersion had greater chemoprophylactic and clinical efficacy than albendazole alone. The improved in therapeutic efficacy could be a consequence of the increase in the systemic availability of albendazole sulfoxide. The work reported here demonstrates that in vivo treatment with albendazole:poloxamer 188 impairs the development of the hydatid cysts. This new pharmacotechnically based strategy could be a suitable alternative for treating cystic echinococcosis in humans. Copyright © 2014 Elsevier B.V. All rights reserved.

    Human cystic echinococcosis is a zoonosis caused by the larval stage of the tapeworm Echinococcus granulosus sensu lato (s. l.). Although benzimidazole compounds such as albendazole (ABZ) and mebendazole have been the cornerstone of chemotherapy for the disease, there is often no complete recovery after treatment. Hence, new strategies are required to improve treatment of human cystic echinococcosis. The goals of the current study were as follows: (i) to evaluate the in vitro efficacy of the 5-fluorouracil (5-FU) and ABZ combination against E. granulosus s. l. protoscoleces and cysts, (ii) to compare the clinical efficacy of 5-FU alone or in combination with ABZ in infected mice. The combination of 5-FU+ABZ had a stronger in vitro effect against larval stage than that did both drugs alone. Even at the lowest concentration of 5-FU+ABZ combination (1μg/ml), the reduction of the viability of protoscoleces and cysts was greater than that observed with drugs alone at 10μg/ml. The results were confirmed at the ultrastructural level by scanning electron microscopy. These data helped to justify the in vivo investigations assessing the therapeutic potential of the combination of 5-FU and ABZ suspension in CF-1 mice infected with E. granulosus sensu stricto (s. s.) metacestodes. Treatment with 5-FU (10mg/kg) or 5-FU (10mg/kg) + ABZ suspension (5mg/kg) reduced the weight of cysts recovered from mice compared with control groups. Interestingly, the effect of 5-FU given weekly for 5 consecutive weeks was comparable to that observed with ABZ suspension under a daily schedule during 30days. Co-administration of 5-FU with ABZ did not enhance the in vivo efficacy of drugs alone calculated in relation to cysts weights. However, the combination provoked greater ultrastructural alterations compared to the monotherapy. In conclusion, we demonstrated the efficacy of 5-FU either alone or co-administrated with ABZ against murine experimental cystic echinococcosis. Since 5-FU treatments

    2011-03-01

    A 10-year (1998-2008) retrospective study was carried out to investigate the prevalence and long-term trend of hydatid disease in slaughtered herbivores in the large complex abattoir of Ahwaz (the capital of Khuzestan province, south-western Iran). A total of 3,583,417 animals including 2,815,982 sheep, 427,790 goats and 339,645 cattle were inspected macroscopically for hydatid cysts in the 10-year period, and overall 155,555 (4.24%) livers and 228,172 (6.37%) lungs were condemned. Cystic echinococcosis (CE) was responsible for 36.08% and 48.04% of total liver and lung condemnations, respectively. The prevalence of pulmonary hydatid disease in sheep, goats and cattle was 2.22, 5.43 and 6.99%, respectively; on the other hand, the prevalence of hepatic hydatid disease for those animals was 1.26, 2.57 and 2.80%, respectively. Data showed an overall downward long-term trend for CE in all livestock slaughtered during the study period (P trend was still observed. The total annual economic loss incurred due to hydatidosis in all ruminants slaughtered at Ahwaz municipal abattoir was estimated to be US$459,659.6, based on the market prices in the year 2008. This number corresponds to a loss of US$300,620.4 for cattle, US$123,490.0 for sheep and US$35,549.2 for goats. The current results provide baseline data for the future monitoring of this potentially important disease in the region, and also suggest that a thorough investigation leading to a disease control strategy is required to reduce the economic and public health consequences of CE.

    Cost-benefit analyses, run before the commencement of a programme to control a parasitic disease, should include estimates of the economic losses attributable to the disease. Uruguay, a middle-income, developing country, has a recent history of persistent problems with cystic echinococcosis, in both its human population and livestock. The economic effects in Uruguay of this disease, caused by the larval stage of the canine tapeworm Echinococcus granulosus, have now been evaluated. Data on the incidence of the disease, in humans and livestock, were used to construct cost estimates. The estimated minimum cost (U.S.$2.9 million/year) was based on the condemnation costs of infected offal together with the actual costs of the hospital treatment of the human cases. The estimate of the maximum cost (U.S.$22.1 million/year) also included the production losses resulting from lower livestock efficiency and the reduced income of individuals with morbidity attributable to the disease.

    2017-03-01

    Full Text Available Echinococcosis is a cosmopolitan zoonotic parasitic disease caused by infection with the larval stage of tapeworms from the Echinococcus genus, most commonly Echinococcus granulosus. According to WHO, more than 1 million people are affected by hydatid disease at any time.1 About 10% of the annual cases are not officially diagnosed.2 In humans, the disease is characterized by development of three-layered cysts. The cysts develop primarily in the liver and the lungs, but can also affect any other organ due to the spreading of the oncospheres. Cardiac involvement is very uncommon - only about 0.01-2% of all cases.4,5 In most cases, the cysts develop asymptomatically, but heart cysts could manifest with chest pain, dyspnea, cough, hemophtisis and can complicate with rupture. Diagnosis is based on a number of imaging techniques and positive serological tests. Treatment for cardiac localization is almost exclusively surgical.

    The World Health Organization (WHO) treatment protocols for cystic echinococcosis (CE) are based on the standardized ultrasound (US) classification. This study examined whether the classification reflected the natural history of CE in untreated and albendazole-treated patients. Data were collected during mass US screenings in CE endemic regions among transhumant populations, the Turkana and Berber peoples of Kenya and Morocco. Cysts were classified using the WHO classification. Patient records occurring prior to treatment, and after albendazole administration, were selected. 852 paired before/after observations of 360 cysts from 257 patients were analyzed. A McNemar-Bowker χ 2 test for symmetry was significant (palbendazole-treated patients was significant (palbendazole-induced changes. Regressions may reflect the stability of CE3B cysts.

    2011-03-01

    Full Text Available Background: Echinococcosis/hydatidosis is considered endemic in Mauritania. The aim of this study is to present an epidemiological study on the echinococcosis in man and animals in the Nouakchott region. Methods: The internal organs from livestock carcasses were inspected for research of hydatid cysts. The hydatid fluid was examined for research of the protoscoleces. Dogs were necropsied for the collect of Echinococcus granulosus.Results: In the Nouakchott Hospital, 24 surgical operation of human hydatid cysts have been per­formed, out of which 50% were localised in the lung, 33% in the liver and 17% elsewhere. Then, the incidence rate would be of 1.2% per 100 000 inhabitants in Mauritania. In the dog, the prevalence rate is 14%. The average number of E. granulosus on the whole dogs is 172 and 1227 on the positive dogs. Concerning the livestock, hydatid cysts found in 30.1% of the dromedary, 5.5% of the cattle and 6.5 of the sheep. The fertility rate of hydatid cysts in humans (75% and camels (76% was significantly higher than that of sheep (24% and cattle (23% (P<0.0001. Hydatid infestation is characterized globally by the dominance of pulmonary localiza­tions in hu­mans (50% and camels (72.7% and in the liver in sheep (76.1% and cattle (82.3%.Conclusion: The differences between prevalence rates, the fertility of hydatid cysts and diversity sites localization observed in humans and camels of one hand and the sheep and cattle on the other hand, depends possibly the strain(s diversity of E. granulosus.

    Canids, particularly dogs, constitute the major source of cystic echinococcosis (CE) infection to humans, with the majority of cases being caused by Echinococcus granulosus (G1 genotype). Canine echinococcosis is an asymptomatic disease caused by adult tapeworms of E. granulosus sensu lato (s.l.). Information on the population structure and genetic variation of adult E. granulosus is limited. Using sequenced data of the mitochondrial cytochrome c oxidase subunit 1 (cox1) we examined the genetic diversity and population structure of adult tapeworms of E. granulosus (G1 genotype) from canid definitive hosts originating from various geographical regions and compared it to that reported for the larval metacestode stage from sheep and human hosts. Echinococcus granulosus (s.s) was identified from adult tapeworm isolates from Kenya, Libya, Tunisia, Australia, China, Kazakhstan, United Kingdom and Peru, including the first known molecular confirmation from Gaza and the Falkland Islands. Haplotype analysis showed a star-shaped network with a centrally positioned common haplotype previously described for the metacestode stage from sheep and humans, and the neutrality indices indicated population expansion. Low Fst values suggested that populations of adult E. granulosus were not genetically differentiated. Haplotype and nucleotide diversities for E. granulosus isolates from sheep and human origin were twice as high as those reported from canid hosts. This may be related to self-fertilization of E. granulosus and/or to the longevity of the parasite in the respective intermediate and definitive hosts. Improved nuclear single loci are required to investigate the discrepancies in genetic variation seen in this study.

  13. Knowledge, Awareness and Practices Regarding Cystic Echinococcosis among Livestock Farmers in Basrah Province, Iraq

    2018-02-01

    Full Text Available Cystic echinococcosis (CE is an endemic neglected parasitic zoonosis in many of the countries of the Middle East. The disease poses a remarkable economic burden for both animals and humans. In this study, we conducted a questionnaire survey among livestock farmers in Basrah province, southern Iraq, in order to evaluate their knowledge and awareness about CE, and to understand some of the risky practices that could contribute to spread and persistence of such disease. Of the interviewed participants (N = 314, 27.4% owned dogs on their farms. Among farmers owning dogs, 76.7% (66/86 never tied up their dogs, and 43% (37/86 indicated feeding uncooked animal viscera to their dogs. The majority (96.5% of the farmers indicated that they did not de-worm their dogs at all. Only 9.8% (31/314 of the respondents indicated eating raw leafy vegetables without washing. Added to that, 32% of the interviewees indicated that they source water for domestic use from a river; meanwhile 94.3% (296/314 of them do not boil water before using it for domestic purposes. Half of the interviewed livestock farmers in Basrah were not aware about how humans get infected with CE disease, and 41.4% (130/314 did not even realize that CE is a dangerous disease to human health. Almost one in three of the respondents who owned dogs on their farms viewed de-worming of their dogs as a low priority practice. This study highlights the gap in knowledge and awareness about CE among the study population. Risky practices associated with dog keeping management and food and water handling practices were identified. The insight from this research could be used to improve the delivery of a health education message relevant to cystic echinococcosis control at the human-animal interface in Iraq.

  14. On the importance of targeting parasite stem cells in anti-echinococcosis drug development

    Directory of Open Access Journals (Sweden)

    Brehm Klaus

    2014-01-01

    Full Text Available The life-threatening diseases alveolar and cystic echinococcoses are caused by larvae of the tapeworms Echinococcus multilocularis and E. granulosus, respectively. In both cases, intermediate hosts, such as humans, are infected by oral uptake of oncosphere larvae, followed by asexual multiplication and almost unrestricted growth of the metacestode within host organs. Besides surgery, echinococcosis treatment relies on benzimidazole-based chemotherapy, directed against parasite beta-tubulin. However, since beta-tubulins are highly similar between cestodes and humans, benzimidazoles can only be applied at parasitostatic doses and are associated with adverse side effects. Mostly aiming at identifying alternative drug targets, the nuclear genome sequences of E. multilocularis and E. granulosus have recently been characterized, revealing a large number of druggable targets that are expressed by the metacestode. Furthermore, recent cell biological investigations have demonstrated that E. multilocularis employs pluripotent stem cells, called germinative cells, which are the only parasite cells capable of proliferation and which give rise to all differentiated cells. Hence, the germinative cells are the crucial cell type mediating proliferation of E. multilocularis, and most likely also E. granulosus, within host organs and should also be responsible for parasite recurrence upon discontinuation of chemotherapy. Interestingly, recent investigations have also indicated that germinative cells might be less sensitive to chemotherapy because they express a beta-tubulin isoform with limited affinity to benzimidazoles. In this article, we briefly review the recent findings concerning Echinococcus genomics and stem cell research and propose that future research into anti-echinococcosis drugs should also focus on the parasite’s stem cell population.

  15. Echinococcosis and other parasitic infections in domestic dogs from urban areas of an Argentinean Patagonian city

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available In urban populations of South America, dogs with free access to public areas represent a public health concern. The primary consequence of roaming dogs on human health is the transmission of infectious and parasitic diseases mainly through feces contamination. The main diseases likely to be transmitted are hydatidosis or echinococcosis, larva migrans, and giardiasis. In Argentina, hydatidosis ranks among the most prevalent zoonosis. Although it is considered a rural disease, the circulation of this parasite in urban areas has been documented. The aim of this work was to survey intestinal parasites in canine feces from two low-income urban neighborhoods of Bariloche city, Argentina, and to assess their seasonal variation. During 2016, 188 fresh dog feces were collected from sidewalks in 40 randomly selected blocks from the neighborhoods. Each sample was processed by Sheater flotation and tested for a coproantigen (CAg by ELISA. The percentage of parasitized feces was 65.3% (95% CI: 55.9%-73.8%. Eleven parasite species were found, 3 protozoan, 3 cestodes, and 5 nematodes. Echinococcus sp. was present in 9.3% of the samples (95% CI: 4.7%-16.1%. Canine echinococcosis rates resulted similar to rates found previously in other neighborhoods of the city. The life cycle of Echinococcus sp. is sustained in urban areas by the entry of parasitized livestock, domiciliary slaughtering, and inadequate deposition of offal. The risk of Echinococcus sp. transmission to people in these neighborhoods is very high, due to high density of free-roaming dogs and high percentages of infected feces, similar to percentages observed in rural areas.

    Full Text Available Cardiac hydatid disease is rare. We report on an uncommon hydatid cyst localized in the right ventricular wall, right atrial wall tricuspid valve left atrium and pericard. A 33-year-old woman was treated for cough, fever and chest pain. Cardiac echocardiograpic examination revealed a round tumor (5.8 x 4 cm in the right ventricular free wall and two smaller cysts behind that tumor. There were cysts in right atrial wall and tricuspidal valve as well. Serologic tests for hydatidosis were positive. Computed tomography finding was consistent with diagnosis of hydatid cyst in lungs and right hylar part. Surgical treatment was rejected due to great risk of cardiac perforation. Medical treatment with albendazole was unsuccessful and the patient died due to systemic hydatid involvement of the lungs, liver and central nervous system.

    Autoimmune hepatitis is chronic liver disease with two subtypes, type 1 with anti nuclear or smooth muscle antibodies and type 2 with LKM1 or LC1 antibodies, and both with hypergammaglobulinemia and typical histology. Prevalence of AIH is between 10 to 17 per 100000 in Europe. Up to 20-40 % of cases present with acute hepatitis. Budesonide can be used as a first line induction therapy in non-cirrhotic patients, and tiopurines, mercaptopurine or mycophenolic acid as maintenance therapies. Patients not responding to conventional therapy can be treated with ciclosporin, tacrolimus or rituximab or finally with liver transplantation.

  16. Subcutaneous infection model facilitates treatment assessment of secondary Alveolar echinococcosis in mice.

    Directory of Open Access Journals (Sweden)

    Tatiana Küster

    Full Text Available Alveolar echinococcosis (AE in humans is a parasitic disease characterized by severe damage to the liver and occasionally other organs. AE is caused by infection with the metacestode (larval stage of the fox tapeworm Echinococcus multilocularis, usually infecting small rodents as natural intermediate hosts. Conventionally, human AE is chemotherapeutically treated with mebendazole or albendazole. There is, however still the need for improved chemotherapeutical options. Primary in vivo studies on drugs of interest are commonly performed in small laboratory animals such as mice and Mongolian jirds, and in most cases, a secondary infection model is used, whereby E. multilocularis metacestodes are directly injected into the peritoneal cavity or into the liver. Disadvantages of this methodological approach include risk of injury to organs during the inoculation and, most notably, a limitation in the macroscopic (visible assessment of treatment efficacy. Thus, in order to monitor the efficacy of chemotherapeutical treatment, animals have to be euthanized and the parasite tissue dissected. In the present study, mice were infected with E. multilocularis metacestodes through the subcutaneous route and were then subjected to chemotherapy employing albendazole. Serological responses to infection were comparatively assessed in mice infected by the conventional intraperitoneal route. We demonstrate that the subcutaneous infection model for secondary AE facilitates the assessment of the progress of infection and drug treatment in the live animal.

    The direct and indirect economic burden of human cystic echinococcosis (CE) was investigated in the five specialist hydatid hospitals in Xinjiang, PR China, to provide information for health policy in the future. A total of 2018 CE patients (age range 2-88 years) attending the hospitals were studied between 2004 and 2008. The per-person direct medical cost was US$1493.12 (95% CI 1438.43-1547.80) and the per-person direct non-medical cost was US$19.67. The indirect economic cost was US$1435.96 per person, and the disability-adjusted life-years (DALY) lost was approximately 1.03 DALY/person. This study is the first to combine the human capital method with DALYs to analyse the indirect CE economic burden in northwest China. Factors such as age, occupation and hospital level should be considered when developing polices to reduce the economic burden of CE. Copyright © 2012 Royal Society of Tropical Medicine and Hygiene.

    Alveolar echinococcosis (AE), a parasitic disease primarily of the liver caused by the larval stage of Echinococcus multilocularis, is highly endemic in Switzerland. In contrast to well-established management protocols in people, little is known with regard to optimal treatment strategies in dogs. The objective of this study was to describe the clinical signs and diagnostic procedures in dogs with AE and to evaluate outcome following medical treatment alone or surgery and medical treatment. Of 23 putative AE cases between 2004 and 2014, 20 were classified as confirmed (n=18) or probable (n=2) AE, based on abdominal ultrasound, serology, cytology, histology and/or PCR. Most dogs presented with abdominal distension in an advanced stage of disease. Dogs receiving specific treatment (radical or debulking surgery together with medical treatment, or medical treatment alone) survived longer than dogs left untreated, but no difference was found between treatment types. Survival at one year was associated with absence of free abdominal fluid, absence of abdominal distension and treatment of any type. However, dogs treated with debulking surgery all faced relapse. Findings of this study suggest that in AE-affected dogs for which a therapeutic approach is regarded appropriate by owners and veterinarians, radical surgical resection and medical treatment or, if total resection is not possible, medical treatment alone should be considered. However, studies on larger numbers of dogs are necessary before definitive treatment recommendations can be made. British Veterinary Association.

    Acute fascioliasis (FA), cystic echinococcosis (CE) and neurocysticercosis (NCC) are three endemic parasitic diseases in Chile for whom there is scarce information about the economic impact they represent during management at the hospital. To quantify and compare hospital care expenses caused by these three endemic helminth infections in a Chilean hospital. Retrospective analysis of hospital costs at a referral hospital in Santiago between 2006 and 2010. Hospital databases were used to identify patients with the corresponding infections, and those with sufficient data on hospital costs were included. A total of 16 patients representing 21 cases were identified and analyzed: four with AF, eleven with CE, and six with NCC. Median hospital expenses for cases with AF were US$ 1799 and mainly caused by bed-day costs. Median hospital costs for cases of CE were US$ 4707 and the most important costs components were medications, bed-day costs and consumables. NCC patients had median costs of US$ 1293, which were mainly due to bed-day costs. Non-parenchymatous or mixed forms of NCC showed a trend toward higher hospital costs compared with parenchymatous forms. Although helminth infections in Chile, an upper middle income country, are declining and considered rare in routine clinical practice, hospital care expenses caused by patients with AF, CE, and NCC are high and might still present an important economic burden to the Chilean healthcare system.

    The Coquimbo Region in Chile has the highest incidence of hydatidosis in central and northern Chile. To analyze the incidence of human cystic echinococcosis (CE) in the Coquimbo Region between 2008 and 2012. Official records of reported cases were analyzed. The association of the location, age and sex with the presence/absence of CE was analyzed by means of logistic regressions. The incidence was reported as cases per 100,000 inhabitants. The mean annual incidence was 2.6 cases per 100,000 inhabitants, which ranged from 3.1 (2010) to 1.9 (2012) cases. The districts with higher incidence were Punitaqui (21.2 cases), Paihuano (9 cases), Rio Hurtado (8 cases), Canela (8.1 cases), Monte Patria (7.9 cases), Vicuña (6.9 cases) and Combarbalá (6.9 cases). The incidence in these locations was significantly higher than elsewhere in the region. Males had a significantly higher incidence than females (3.3 and 1.8 respectively). Incidence increased significantly with age, notably increasing after 45 years of age. Rural locations had the highest incidences of CE in the Coquimbo Region. The disease was reported more commonly in adults and mainly in men.

    The most highly developed radioimmunoassay test system in medical virology is proving of exceptional value in research aimed at controlling and eventually eradicating the scourge of human hepatitis. The use of radioimmunoassay in detecting hepatitis A (HAV) and hepatitis B (HBV) viruses is discussed. The hepatitis A virus is an enterovirus which infects the gastrointestinal tract and is usually transmitted by contaminated food, milk or water. Hepatitis B spreads mainly by the parenteral rate. Bedbugs and ticks are considered as possible transmitters of HBV. Another important contribution of radioimmunoassay is the ability to monitor the immune response of persons at risk who are vaccinated against hepatitis B.

Semua usia dan jenis kelamin dapat dikenai dengan insiden tertinggi pada anak perempuan usia prepubertas, meskipun dapat didiagnosis pada usia 6 bulan. Hepatitis autoimun dapat diklasifikasikan menjadi 2 bagian berdasarkan adanya antibodi spesifik: Smooth Muscle Antibody (SMA dengan anti-actin specificity dan/atau Anti Nuclear Antibody (ANA pada tipe 1 dan Liver-Kidney Microsome antibody (LKM1 dan/atau anti-liver cytosol pada tipe 2. Gambaran histologisnya berupa “interface hepatitis”, dengan infiltrasi sel mononuklear pada saluran portal, berbagai tingkat nekrosis, dan fibrosis yang progresf. Penyakit berjalan secara kronik tetapi keadaan yang berat biasanya menjadi sirosis dan gagal hati.Tipe onset yang paling sering sama dengan hepatitis virus akut dengan gagal hati akut pada beberapa pasien; sekitar sepertiga pasien dengan onset tersembunyi dengan kelemahan dan ikterik progresif ketika 10-15% asimptomatik dan mendadak ditemukan hepatomegali dan/atau peningkatan kadar aminotransferase serum. Adanya predominasi perempuan pada kedua tipe. Pasien LKM1 positif menunjukkan keadaan lebih akut, pada usia yang lebih muda, dan biasanya dengan defisiensi Immunoglobulin A (IgA, dengan durasi gejala sebelum diagnosis, tanda klinis, riwayat penyakit autoimun pada keluarga, adanya kaitan dengan gangguan autoimun, respon pengobatan dan prognosis jangka panjang sama pada kedua tipe.Kortikosteroid yang digunakan secara tunggal atau kombinasi azathioprine merupakan terapi pilihan yang dapat menimbulkan remisi pada lebih dari 90% kasus.

    Autoimmune hepatitis (AIH) is characterised histologically by interface hepatitis, and serologically by the presence of non-organ and liver specific autoantibodies and increased levels of immunoglobulin G. Its onset is often ill-defined, frequently mimicing acute hepatitis. AIH usually responds to immunosuppressive treatment, which should be instituted as soon as diagnosis is made. Two types of AIH are recognized according to seropositivity for smooth muscle and/or antinuclear antibody (SMA/ANA, type 1 AIH) or liver kidney microsomal type 1 antibody (LKM1, type 2 AIH). There is a female predominance in both. LKM1 positive patients tend to present more acutely, at a younger age and commonly have immunoglobulin A deficiency, while duration of symptoms before diagnosis, clinical signs, family history of autoimmunity, presence of associated autoimmune disorders, response to treatment and long-term prognosis are similar in the 2 groups. Susceptibility to AIH type 1 is conferred by possession of HLA DR3 and DR4, while to AIH type 2 by possession of HLA DR7. Liver damage is likely to derive from an immune reaction to liver cell antigens, possibly triggered by a mechanism of molecular mimicry, where immune responses to external pathogens, e.g. viruses, become directed towards structurally similar self-components. In AIH this process would be perpetuated by impairment in immune regulation.

    Cystic echinococcosis (CE) is a widespread zoonosis caused by the species complex Echinococcus granulosus. Albendazole (ABZ)-the first-line anthelminthic drug for medical treatment of CE-is metabolized in vivo to the active derivative ABZ-sulphoxide (ABZ-SO). Target-site ABZ-SO concentrations in the hydatid cyst mediate the anthelminthic effect in CE. Primary outcome of this systematic review of individual patient data was the intra-cystic ABZ-SO concentration stratified by cyst size, location, calcification status and use of praziquantel. Studies reporting intra-cystic ABZ-SO concentrations in humans were identified by a systematic search. A pooled analysis of individual patient data was performed to assess intra-cystic concentrations. Pharmacokinetic data of 121 individual cysts were analysed. There was no correlation between plasma and intra-cystic ABZ-SO concentrations (rho = -0.03, p = 0.76). Intra-cystic drug concentrations were also not associated with sex and treatment duration. Use of praziquantel in combination with ABZ was associated with higher plasma (median 540 vs. 240 μg/L; p = 0.04) but not intra-cystic ABZ-SO concentrations (median 220 vs. 199 μg/L; p = 0.36). Relative drug concentrations in hepatic cysts were higher than in other cysts (0.8 vs. 0.4; p = 0.05). Intra-cystic concentrations were higher in calcified than non-calcified cysts (median 897 vs. 245 μg/L; p = 0.03). There was a trend towards higher intra-cystic concentrations in smaller sized cysts (β = -17.2 μg/L/cm; 95th CI, -35.9 to 1.6; p = 0.07). This study demonstrates that mean intra-cystic drug concentrations are similar to plasma concentrations on a population level. However, in individual patients plasma concentrations are not directly predictive for intra-cystic concentrations. The use of booster drugs was not associated with higher intra-cystic ABZ-SO concentrations in this analysis.

    Full Text Available Cystic echinococcosis (CE is an important health problem in many areas of the world including the Mediterranean region. However, the real CE epidemiological situation is not well established. In fact, it is possible that CE is a re-emerging disease due to the weakness of current control programs.We performed a retrospective observational study of inpatients diagnosed with CE from January 2000 to December 2012 in the Western Spain Public Health-Care System.During the study period, 5510 cases of CE were diagnosed and 3161 (57.4% of the cases were males. The age mean and standard deviation were 67.8 ± 16.98 years old, respectively, and 634 patients (11.5% were younger than 45 years old. A total of 1568 patients (28.5% had CE as the primary diagnosis, and it was most frequently described in patients 70 year old associated with other causes of comorbidity. The period incidence rate was 17 cases per 105 person-years and was significantly higher when compared to the incidence declared through the Notifiable Disease System (1.88 cases per 105 person-years; p<0.001.CE in western Spain is an underestimated parasitic disease. It has an active transmission, with an occurrence in pediatric cases, but has decreased in the recent years. The systematic search of Hospital Discharge Records of the National Health System Register (HDR may be a more accurate method than other methods for the estimation of the incidence of CE in endemic areas.

    Human cystic and alveolar echinococcosis are helmintic zoonotic diseases caused by infections with the larval stages of the cestode parasites Echinococcus granulosus and E. multilocularis, respectively. Both diseases are progressive and chronic, and often fatal if left unattended for E. multilocularis. As a treatment approach, chemotherapy against these orphan and neglected diseases has been available for more than 40 years. However, drug options were limited to the benzimidazoles albendazole and mebendazole, the only chemical compounds currently licensed for treatment in humans. To compensate this therapeutic shortfall, new treatment alternatives are urgently needed, including the identification, development, and assessment of novel compound classes and drug targets. Here is presented a thorough overview of the range of compounds that have been tested against E. granulosus and E. multilocularis in recent years, including in vitro and in vivo data on their mode of action, dosage, administration regimen, therapeutic outcomes, and associated clinical symptoms. Drugs covered included albendazole, mebendazole, and other members of the benzimidazole family and their derivatives, including improved formulations and combined therapies with other biocidal agents. Chemically synthetized molecules previously known to be effective against other infectious and non-infectious conditions such as anti-virals, antibiotics, anti-parasites, anti-mycotics, and anti-neoplastics are addressed. In view of their increasing relevance, natural occurring compounds derived from plant and fungal extracts are also discussed. Special attention has been paid to the recent application of genomic science on drug discovery and clinical medicine, particularly through the identification of small inhibitor molecules tackling key metabolic enzymes or signalling pathways.

    Although cystic echinococcosis (CE) is highly endemic in Bulgaria, there is still scarce information about species and/or genotypes of the Echinococcus granulosus complex that infect humans. Our study tackled the genetic diversity of E. granulosus complex in a cohort of 30 Bulgarian CE patients. Ten animal E. granulosus isolates from neighboring Greece were additionally included. Specimens were comparatively analyzed for partial sequences of five mitochondrial (mt) (cox I, nad I, rrnS, rrnL, and atp6) and three nuclear (nc) genes (act II, hbx 2, and ef-1α) using a PCR-sequencing approach. All 30 Bulgarian isolates were identified as E. granulosus sensu stricto (s.s.) and were showing identical sequences for each of the three examined partial nc gene markers. Based upon concatenated sequences from partial mtDNA markers, we detected 10 haplotypes: 6 haplotypes (H1-H6) clustering with E. granulosus s.s. (G1) and 4 haplotypes (H9-H13) grouping with E. granulosus s.s. (G3), with H1 and H10 being the most frequent in Bulgarian patients. The haplotypes H1, H4, and H11 were also present in Greek hydatid cyst samples of animal origin. In conclusion, E. granulosus s.s. (G1 and G3 genotypes) is the only causative agent found so far to cause human CE in Bulgaria. However, further studies including larger sample sizes and other additional geographic regions in Bulgaria will have to be performed to confirm our results.

    A study monitoring cystic echinococcosis (CE) in adult dairy cattle from intensive livestock farms located in the municipality of Arborea (Sardinia, Italy) was carried out between 2012 and 2015. A retrospective study of veterinary reporting forms of post-mortem inspections in 10 different Italian slaughterhouses was also performed. In addition, data on viability and molecular characterisation of hydatid cysts removed from parasitised organs in cattle was carried out. A geographical information system (GIS) with data layers of the study area and the geo-referenced points of 160 cattle farms was constructed. CE was found in 21.9% (35/160) of the surveyed farms. The retrospective study revealed that 0.05% (13/23,656) of adult slaughtered animals (over one year of age) from Arborea had tested positive to CE. The results stratified per year showed the following CE prevalences: 0.09% (5/5673) in 2012; 0.02% (1/5682) in 2013; 0.08% (5/6261) in 2014; and 0.03% (2/6040) in 2015 (χ2 with 3 degrees of freedom=3.81; P=0.282). The E. granulosus sensu stricto (formerly called G1 or sheep strain) was detected in all cysts subjected to molecular analysis. The GIS analysis showed that CE is fairly resilient in the Arborea territory where most of cattle farms are located, while a small cluster of cases was found located in the southeastern part of Arborea, close to districts where sheep farms are situated. The present survey reports the presence of CE in Sardinian dairy cattle intensive farms and suggests that the parasitic pressure of CE in the island continues to be very strong.

    Full Text Available The aim of the present study was to examine serum cytokines and nitric oxide (NO levels in patients with cystic echinococcosis (CE. 28 patients with CE were studied and all underwent surgery. Serum levels of tumour necrosis factor-alpha (TNF-α, interleukin IL- 1β, receptor of soluble IL-2R (sIL-2R, IL-6, IL-8, nitrate/nitrite, and C-reactive protein (CRP were determined before and after induction of treatment. Data were compared with those obtained from 28 healthy volunteers. IL-6 was elevated in all CE patients (100%. IL-8 was increased in 11/28 (39.3%. Increased levels of IL-2R and TNF-α were found in a limited number of them particularly those showing cysts in the central area of the liver (5/28, 6/28. IL-1β level was not elevated in any patient except in secondary severe CE. CRP and nitrate/nitrite levels were also increased. A positive correlation between CRP and IL-6 (r = 0.74; p < 0.001 was found confirming the link between inflammation due to CE and activation of monocytes. All patients completely recovered and the levels of the studied parameters reverted to normal levels except one patient in whom severe recurrent disease occurred two years after the first operation. These results suggest that there are different immunoregulatory events and cytokines response during CE and may be in part related to slight monocytosis and in part to Th2 activation. IL-6, NO and CRP were unambiguously involved in the host parasite interaction and therefore may be useful markers in monitoring CE management and evaluating surgical stress.

    Full Text Available Cystic echinococcosis (CE, a zoonotic parasitic infection caused by the metacestode (larvae stage of dog tapeworm Echinococcus granulosus and recognized as a major economic and public health concern in the world. This study aimed to investigate the in vitro scolicidal effect of methanolic extract of Berberis vulgaris L. roots and its main compound, berberine against protoscoleces of hydatid cysts.For this purpose, protoscoleces were aseptically aspirated from sheep livers having hydatid cysts. Various concentrations of the methanolic extract (0.25-2 mg/ml and berberine (0.062- 0.5 mg/ml were used for 5 to 30 min. Viability of protoscoleces was confirmed by eosin exclusive test.In the present study, all of the various concentrations of the B. vulgaris methanolic extract (0.25, 0.5, 1 and 2 mg/ml and berberine (0.062, 0.125, 0.25 and 0.5 mg/ml revealed significant (P<0.05 scolicidal effects against protoscoleces of E. granulosus in a dose-dependent manner. Both berberine and methanolic extract exhibited 100% inhibition against protoscoleces of E. granulosus at the concentration of 2.0 and 0.5 mg/ml after 10 min incubation, respectively.According to the results, both B. vulgaris methanolic extract and berberine alone demonstrated high scolicidal activities against protoscoleces of hydatid cysts in low concentration and short exposure time on in vitro model. However, in vivo efficacy of B. vulgaris and berberine also requires to be evaluated using an animal model with hydatid infection.

    In the present study we investigated cytokine mRNA expression by peripheral blood mononuclear cells (PBMC) from patients with cystic echinococcosis (CE) after stimulation with different antigens. By using reverse transcriptase polymerase chain reaction (RT-PCR) we could demonstrate that restimulation with crude Echinococcus granulosus antigen (Eg-Ag) induced or enhanced Th2 cytokine mRNA expression, especially IL-5 (by using antigen from sheep cyst fluid) in 23 out of 26 investigated CE patients and IL-10 (by using antigen from camel cyst fluid) in 10 out of 10 investigated CE patients. In contrast, IL-5 mRNA expression was absent in PBMC of healthy controls after Eg-Ag stimulation. To determine the specificity of this reaction we stimulated PBMC from 11 CE patients with crude Echinococcus multilocularis antigen (Em-Ag) and PBMC from 8 CE patients with Toxocara canis antigen (Tc-Ag). We found that the PBMC of patients showed a similar mRNA cytokine pattern on stimulation with Em-Ag when compared with Eg-Ag stimulation. The cytokine mRNA pattern on stimulation with Tc-Ag, however, resembled the cytokine mRNA pattern of unstimulated PBMC. Furthermore, the stimulation of PBMC with crude Mycobacterium tuberculosis antigen (H37Ra) and purified protein derivative (PPD) of M. tuberculosis revealed distinct IL-5 mRNA expression in all investigated CE patients, whereas in healthy controls IL-5 mRNA expression was very weak or totally absent. Thus, our results indicate an induction of Th2 cytokine mRNA expression in CE patients, which is frequently observed in parasite infections. Interestingly, this response persists after stimulation with tuberculosis antigens, which normally induce Th1 response.

    To determine the susceptibility genes and resistance genes in HLA-DRB1 alleles in Tibetan patients with cystic and alveolar hydatid diseases, so as to provide the references for the research of the genetic characteristics and infection mechanism of Tibetan hydatid diseases. The case control method was applied. The Tibetan patients with cystic and alveolar hydatid diseases (63 and 73 cases respectively) in Yushu and Guoluo Tibetan Autonomous Prefecture, and unrelated healthy people (60 cases) in this area were selected as the study subjects. The polymerase chain reaction-sequence based typing (PCR-SBT) technique was applied for genotyping of HLA-DRB1, and the comparison of the gene frequency. The frequency of HLA-DRB1*04 in the alveolar/cystic echinococcosis group was lower than that in the control group ( χ 2 = 4.71, 4.31, both P < 0.05). HLA-DRB1*04 genotypes may be associated with the resistance of cystic and alveolar echinococcosis and its resistance genes.

    Cystic echinococcosis caused by the larval stages of Echinococcus granulosus sensu lato s.l is endemic in Turkey with a high public health impact particularly in rural areas. The aim of this study was to investigate the genetic variation and population structure of E. granulosus s.s using metacestode isolates removed from surgically confirmed patients originating from several regions in Turkey and to investigate the occurrence of autochthonous transmission. Using DNA extracted from a total of 46 human-derived CE isolates, we successfully analysed an 827-bp fragment within the cox1 mitochondrial gene and confirmed the causative agent of human cystic echinococcosis in patients included in this study to be Echinococcus granulosus s.s (G1 and G3 genotypes). The haplotype parsimony network consisted of 28 haplotypes arranged within three main clusters and the neutrality indices were both negative and significant indicating negative selection or population expansion. The assessment carried out in this study using GenBank nucleotide sequence data from Turkey for sheep and cattle hosts demonstrated the importance of autochthonous transmission with sheep, cattle and humans harbouring the same haplotypes. Further studies are required to investigate the biological significance, if any, of E. granulosus s.s haplotypes and the genetic variability of CE from human patients using longer nucleotide sequences and a larger sample set.

    Cystic echinococcosis (CE) is a chronic zoonosis which presents with variable clinical manifestations. Currently the diagnosis of this disease is based on radiological findings and serological tests which lack specificity. Although antigen detection from the cyst fluid is the most specific, it is seldom done due to the complications involved. Detecting the presence of Echinococcus granulosus specific deoxyribonucleic acid (DNA) by the polymerase chain reaction (PCR) could provide a definitive diagnosis of CE. An in-house PCR assay was devised to detect E. granulosus specific DNA in serum, urine and hydatid cyst fluid. The ability of the PCR to detect E. granulosus in the above mentioned samples were observed in comparison with other antigen and antibody detection tests. Serum samples from surgically confirmed patients of CE with ruptured cysts contained the corresponding DNA while the in the majority of cases who had an intact cyst had no DNA of E. granulosus in their serum. DNA of E. granulosus was not found to be excreted in urine. PCR performed equal to antigen detection ELISA while testing hydatid cyst fluid samples. Serum and urine might not serve as useful samples for the molecular diagnosis of cystic echinococcosis. However, PCR can be useful on serum samples to detect ruptured hydatid cysts and on hydatid cyst fluid to confirm the parasitic diagnosis.

    Human alveolar echinococcosis (AE) is a severe zoonotic disease caused by the metacestode stage of Echinococcus multilocularis. AE is commonly associated with a long incubation period that may last for more than ten years. The objective of this systematic literature review was to identify and summarize the current knowledge on statistically relevant potential risk factors (PRFs) associated with AE in humans. Six bibliographic databases were searched, generating a total of 1,009 publications. Following the removal of duplicate records and the exclusion of papers that failed to meet the criteria of a previously agreed a priori protocol, 23 publications were retained; however, 6 of these did not contain data in a format that allowed their inclusion in the meta-analysis. The remaining 17 publications (6 case-control and 11 cross-sectional studies) were meta-analysed to investigate associations between AE and PRFs. Pooled odds ratios (OR) were used as a measure of effect and separately analysed for case-control and cross-sectional studies. In the case-control studies, the following PRFs for human AE showed higher odds of outcome: "dog ownership", "cat ownership", "have a kitchen garden", "occupation: farmer", "haymaking in meadows not adjacent to water", "went to forests for vocational reasons", "chewed grass" and "hunting / handling foxes". In the cross-sectional studies, the following PRFs showed higher odds of outcome: "dog ownership", "play with dogs", "gender: female", "age over 20 years", "ethnic group: Tibetan", "low income", "source of drinking water other than well or tap", "occupation: herding" and "low education". Our meta-analysis confirmed that the chance of AE transmission through ingestion of food and water contaminated with E. multilocularis eggs exists, but showed also that food- and water-borne PRFs do not significantly increase the risk of infection. This systematic review analysed international peer-reviewed articles that have over the years

    Full Text Available Cystic echinococcosis (CE is an important neglected zoonotic parasitic infection belonging to the subgroup of seven Neglected Zoonotic Disease (NZDs included in the World Health Organization's official list of 18 Neglected Tropical Diseases (NTDs. CE causes serious global human health concerns and leads to significant economic losses arising from the costs of medical treatment, morbidity, life impairments and fatality rates in human cases. Moreover, CE is endemic in several Italian Regions. The aim of this study is to perform a detailed analysis of the economic burden of hospitalization and treatment costs and to estimate the Disability Adjusted Life Years (DALYs of CE in Italy.In the period from 2001 to 2014, the direct costs of 21,050 Hospital Discharge Records (HDRs belonging to 12,619 patients with at least one CE-related diagnosis codes were analyzed in order to quantify the economic burden of CE. CE cases average per annum are 901 (min-max = 480-1,583. Direct costs include expenses for hospitalizations, medical and surgical treatment incurred by public and private hospitals and were computed on an individual basis according to Italian Health Ministry legislation. Moreover, we estimated the DALYs for each patient. The Italian financial burden of CE is around € 53 million; the national average economic burden per annum is around € 4 million; the DALYs of the population from 2001 to 2014 are 223.35 annually and 5.26 DALYs per 105 inhabitants.In Italy, human CE is responsible for significant economic losses in the public health sector. In humans, costs associated with CE have been shown to have a great impact on affected individuals, their families and the community as a whole. This study could be used as a tool to prioritize and make decisions with regard to a surveillance system for this largely preventable yet neglected disease. It demonstrates the need of implementing a CE control program aimed at preventing the considerable economic

    The past several years have seen significant advances in diagnostic and interventional radiology. These advances have been particularly rewarding for the study of liver disease. Improved imaging and therapeutic procedures in oncology have generated changes in treatment protocols and in evaluating the results of therapy for hepatic malignancies. The enriched understanding of the anatomic and hemodynamic aspects of the portal system has greatly benefited patients with portal hypertension. Now physicians are confidently more aggressive in the therapeutic approach to the variceal bleeder, and they have modified their approach to the preservation of portal flow following shunt. All of the diagnostic modalities used to evaluate the liver are represented in this book. In its structure and organization this volume goes beyond a historical overview of imaging to present greater insight into the current state of the art, as well as possible future developments. Each chapter is designed to elucidate the advantages and weaknesses of the various diagnostic modalities

    Few molecular studies have identified the current status of cystic echinococcosis in Egypt. The present study aimed to ascertain the genotype(s) of Echinococcus granulosus responsible for human hydatidosis in different Egyptian governorates (regions). Animal isolates were collected from 40 camels, 5 pigs and 44 sheep. 27 human isolates were included in the present study. Specific PCR was performed and followed by DNA sequencing for mitochondrial 12S ribosomal RNA gene and BLAST analysis.The sheep cysts were not hydatid cysts. G6 genotype (camel starin) predominates in human, camel and pig isolates. G7 genotype (pig strain) was detected in two human isolates and one pig isolate. G1 genotype (sheep strain) was detected in one human isolate from Yemen and in no animal isolates. This is the first record of G7 in Egypt and G1 in Yemen.

    Full Text Available Overdiagnosis and overtreatment are rarely discussed in the context of NTDs despite their relevance for patients under the care of health services with limited resources where the risks of therapy induced complications are often disproportionate to the benefit. The advantages of cyst staging-based management of patients with cystic echinococcosis (CE are not yet fully explored. Questions are: Do inactive cysts (CE 4 and CE 5 need treatment and is there a difference between cysts which reach CE4 and CE5 naturally or by benzimidazole therapy?Analysis of long-term follow-up data from a prospective CE patient cohort of 223 patients of a national clinical center for echinococcosis. The event of interest "relapse" was defined as the reversal of a cyst from an inactive stage (CE4, CE5 back to an active stage. The watch &wait (ww group included 30 patients with 46 inactive cysts who never received medical treatment. The benzimidazole-treated (med group included 15 patients with 17 cysts. There was no relapse in the ww-group whereas 8/17 cysts showed relapse within 18 months after treatment in the med-group. Loss to follow-up was 15.5%.Data from the watch & wait group impressively show how stable naturally inactivated cysts are in contrast to cysts which reach inactivity through treatment with benzimidazoles. A substantial proportion of patients can be spared from treatment through cyst staging. Cysts which inactivated through a natural course do not relapse with very high likelihood. We recommend follow up of 5 years to confirm the stability of the inactive stage. Cysts driven into inactivity through benzimidazole therapy instead need careful monitoring to identify those which reactivate (around 50% within 18 months. 5 years follow-up appears safe to make a final decision on the need for further monitoring.

    Considering the geographical asymmetric distribution of viral hepatitis A, B and E, having a much higher prevalence in the less developed world, travellers from developed countries are exposed to a considerable and often underestimated risk of hepatitis infection. In fact a significant percentage of viral hepatitis occurring in developed countries is travel related. This results from globalization and increased mobility from tourism, international work, humanitarian and religious missions or other travel related activities. Several studies published in Europe and North America shown that more than 50% of reported cases of hepatitis A are travel related. On the other hand frequent outbreaks of hepatitis A and E in specific geographic areas raise the risk of infection in these restricted zones and that should be clearly identified. Selected aspects related with the distribution of hepatitis A, B and E are reviewed, particularly the situation in Portugal according to the published studies, as well as relevant clinical manifestations and differential diagnosis of viral hepatitis. Basic prevention rules considering enteric transmitted hepatitis (hepatitis A and hepatitis E) and parenteral transmitted (hepatitis B) are reviewed as well as hepatitis A and B immunoprophylaxis. Common clinical situations and daily practice "pre travel" advice issues are discussed according to WHO/CDC recommendations and the Portuguese National Vaccination Program. Implications from near future availability of a hepatitis E vaccine, a currently in phase 2 trial, are highlighted. Potential indications for travellers to endemic countries like India, Nepal and some regions of China, where up to 30% of sporadic cases of acute viral hepatitis are caused by hepatitis E virus, are considered. Continued epidemiological surveillance for viral hepatitis is essential to recognize and control possible outbreaks, but also to identify new viral hepatitis agents that may emerge as important global health

    2014-10-01

    Alcoholic hepatitis (AH) is an acute inflammatory syndrome causing significant morbidity and mortality. The prognosis is strongly dependent on disease severity, as assessed by clinical scoring systems. Reliable epidemiological data as well as knowledge of the clinical course of AH are essential for planning and resource allocation within the health care system. Likewise, individual evaluation of risk is desirable in the clinical handling of patients with AH as it can guide treatment, improve patient information, and serve as strata in clinical trials. The present PhD thesis is based on three studies using a cohort of nearly 2000 patients diagnosed with AH in Denmark from 1999 to 2008 as a cohort, in a population-based study design. The aims of this thesis were as follows. (1) To describe the incidence and short- and long-term mortality, of AH in Denmark (Study I). (2) To validate and compare the ability of the currently available prognostic scores to predict mortality in AH (Study II). (3) To investigate the short- and long-term causes of death of patients with AH (Study III). During the study decade, the annual incidence rate in the Danish population rose from 37 to 46 per 106 for men and from 24 to 34 per 106 for women. Both short- and long-term mortality rose for men and women, and the increase in short-term mortality was attributable to increasing patient age and prevalence of cirrhosis. Our evaluation of the most commonly used prognostic scores for predicting the mortality of patients with AH showed that all scores performed similarly, with Area under the Receiver Operator Characteristics curves giving values between 0.74 and 0.78 for 28-day mortality assessed on admission. Our study on causes of death showed that in the short-term (thesis provides novel warranted epidemiological information about AH that shows increasing incidence and mortality rates. Consequently, it reiterates the fact that AH is a life-threatening disease and suggests that AH is an

    Hepatic encephalopathy occurs in patients with chronic hepatic insufficiency and can produce abnormalities in the central nervous system, which can be observed in MRI studies. Traditionally, these imaging findings include symmetrical hyper intensities in T1-weighted sequences in the basal ganglia (mainly globus pallidus), involving also the substantia nigra, mesencephalic tegmentum, frontal and occipital cortex. These areas appear of normal intensity in T2-weighted imaging sequences. Other entities that can lead to similar findings include manganese intoxication and type-1 neurofibromatosis. Currently, with the advent of MR spectroscopy, abnormalities in patients with clinical and subclinical hepatic encephalopathy have been described. After hepatic transplantation, hyper intensities of the basal ganglia and the MR spectroscopic findings may disappear within 3 months to 1 year, suggesting a functional, more than a structural damage. This article will demonstrate the MR findings of patients with hepatic encephalopathy due to chronic hepatic insufficiency.

    Cystic echinococcosis (CE) is a globally distributed zoonosis caused by the Echinococcus granulosus sensu lato species complex. Four approaches are available for treatment of abdominal CE: surgery, percutaneous aspiration, chemotherapy with albendazole, and watch-and-wait. Allocation of patients to these different treatment options mainly depends on the stage of the cystic lesion. However, as available guidelines are not widely followed, surgery is often applied even without the correct indication outside referral centers. This is not only a disadvantage for the patient, but also a waste of money. In this study, we evaluated the cost of the surgical approach for abdominal CE by analyzing hospitalization costs for 14 patients admitted to the General Surgery Ward at the "San Matteo" Hospital Foundation in Pavia, Italy, from 2008 through 2014. We found that the total cost of a single hospitalization, including hospital stay, surgical intervention, personnel, drugs, and administrative costs ranged from €5,874 to 23,077 (median €11,033) per patient. Our findings confirm that surgery can be an expensive option. Therefore, surgical intervention should be limited to cyst types that do not benefit from nonsurgical therapies and appropriate case management can best be accomplished by using a cyst stage-specific approach. © The American Society of Tropical Medicine and Hygiene.

    Therapeutic failures attributed to medical management of cystic echinococcosis (CE) with albendazole (ABZ) have been primarily linked to the poor drug absorption rate resulting in low drug level in plasma and hydatid cysts. Lipid nanocapsules (LNCs) represent nanocarriers designed to encapsulate lipophilic drugs, such as ABZ. The goals of the current work were: (i) to characterize the plasma and cyst drug exposure after the administration of ABZ as ABZ-LNCs or ABZ suspension (ABZ-SUSP) in mice infected with Echinococcus granulosus, and ii) to compare the clinical efficacies of both ABZ formulations. Enhanced ABZ sulphoxide (ABZ-SO) concentration profiles were obtained in plasma and cysts from ABZ-LNC treated animals. ABZSO exposure (AUC0-LOQ) was significantly higher in plasma and cyst after the ABZ-LNC treatments, both orally and subcutaneously, compared to that observed after oral administration of ABZ-SUSP. Additionally, ABZSO concentrations measured in cysts from ABZ-LNC treated mice were 1.7-fold higher than those detected in plasma. This enhanced drug availability correlated with an increased efficacy against secondary CE in mice observed for the ABZ-LNCs, while ABZ-SUSP did not reach differences with the untreated control group. This new pharmacotechnically-based strategy could be a potential alternative to improve the treatment of human CE. Copyright © 2015 Elsevier B.V. All rights reserved.

    Renewed interest in hepatic artery infusion has been stimulated by the development of a totally implantable pump which eliminates many of the problems encountered by the external pumps and catheters. As the potential benefit of hepatic artery infusion would be greater if either all gross disease were removed by prior resection, or alternatively, if non-resectable disease were irradiated in conjunction with hepatic artery infusion, the authors initiated a phase I-II trial to evaluate combined modality therapy

    Isolated hepatic tuberculosis without pulmonary or bowel involvement is a diagnostic challenge and can cause considerable morbidity. A young lady from Lahore presented with fever, pain in right hypochondria, nausea and weight loss. CT scan of abdomen showed multiple small hypodense non-enhancing lesions and a heterogeneous texture of liver. Biopsy confirmed the diagnosis of hepatic tuberculosis. It was concluded a case of isolated hepatic tuberculosis without evidence of other primary sites involvement. It is important to consider tuberculosis in the differential diagnosis when suspecting lymphoproliferative or metastatic diseases in a patient with vague symptoms and abnormal hepatic texture on CT.

    A description is presented of a radioimmunoassay designed to prove the presence of the antibody against the hepatitis A virus (HA Ab, anti-Ha) using an Abbott HAVAB set. This proof as well as the proof of the antibody against the nucleus of the hepatitis B virus is based on competition between a normal antibody against hepatitis A virus and a 125 I-labelled antibody for the binding sites of a specific antigen spread all over the surface of a tiny ball; this is then indirect proof of the antibody under investigation. The method is described of reading the results from the number of impulses per 60 seconds: the higher the titre of the antibody against the hepatitis A virus in the serum examined, the lower the activity of the specimen concerned. The rate is reported of incidence of the antibody against the hepatitis A virus in a total of 68 convalescents after hepatitis A; the antibody was found in 94.1%. The immunoglobulin made from the convalescents' plasma showed the presence of antibodies in dilutions as high as 1:250 000 while the comparable ratio for normal immunoglobulin Norga was only 1:2500. Differences are discussed in the time incidence of the antibodies against the hepatitis A virus, the antibodies against the surface antigen of hepatitis B, and the antibody against the nucleus of the hepatitis V virus.

    Full Text Available Introduction: Hepatic hydatid cyst is caused by echinococcosis granulosis. It is a major health problem in endemic areas. The modern treatment of hydatid cysts of the liver varies from surgical intervention to percutaneous drainage or medical therapy. A high rate of complications following percutaneous drainage, and ineffectiveness of medical therapy have shown not to be the definitive treatments for the disease. Thus, surgery is still the best choice for the treatment of hydatid cyst of the liver. Surgical treatment methods can be divided into radical and conservative approaches. There is controversy regarding efficacy of the two surgical methods. In this study, we aimed to present a retrospective evaluation of the two surgical methods in patients treated for the hepatic hydatid cyst. Methods: This retrospective study reviewed medical records of 135 patients who underwent surgery for hepatic hydatid cyst from 1997 to 2007. Surgery comprised conservative methods (evacuation of the cyst content and excision of the inner cyst layers and radical methods (total excision of the cyst and removal of its outer layer. Results: One hundred thirty five patients underwent liver surgery. Conservative surgery was performed for 71 (53%, whereas, the remaining 64 patients (47% underwent radical surgery. Postoperative complications were 28% and 19%, respectively. Recurrence of the cyst in the conservative and radical surgery groups was noted to be 12.5 and 1.5%, respectively. The mean length of hospital stay was shorter in the radical surgery group (5 vs. 15 days. Conclusion: Radical surgery may be the preferred treatment for the hepatic hydatid cyst because of its low rate of postoperative complications and recurrence, as well as short hospital stay. Selection of the most appropriate treatment depends on the size, number, and location of the cyst(s, and presence of cystobiliary communications, and the availability of an experienced surgeon.

    To systematically review publications on Echinococcus granulosus sensu lato species/genotypes reported in domestic intermediate and definitive hosts in South America and in human cases worldwide, taking into account those articles where DNA sequencing was performed; and to analyse the density of each type of livestock that can act as intermediate host, and features of medical importance such as cyst organ location. Literature search in numerous databases. We included only articles where samples were genotyped by sequencing since to date it is the most accurate method to unambiguously identify all E. granulosus s. l. genotypes. Also, we report new E. granulosus s. l. samples from Argentina and Uruguay analysed by sequencing of cox1 gene. In South America, five countries have cystic echinococcosis cases for which sequencing data are available: Argentina, Brazil, Chile, Peru and Uruguay, adding up 1534 cases. E. granulosus s. s. (G1) accounts for most of the global burden of human and livestock cases. Also, E. canadensis (G6) plays a significant role in human cystic echinococcosis. Likewise, worldwide analysis of human cases showed that 72.9% are caused by E. granulosus s. s. (G1) and 12.2% and 9.6% by E. canadensis G6 and G7, respectively. E. granulosus s. s. (G1) accounts for most of the global burden followed by E. canadensis (G6 and G7) in South America and worldwide. This information should be taken into account to suit local cystic echinococcosis control and prevention programmes according to each molecular epidemiological situation. © 2015 John Wiley & Sons Ltd.

    Full Text Available Aim: Echinococcosis or hydatidosis (due to the larval stage of Echinococcus spp. and cysticercosis (due to the larval stage of Taenia hydatigena pose a significant economic losses due to slaughter condemnation and risk to public health in developing countries such as Tanzania where sanitation is poor and people live in close proximity with each other and with animals. This study was conducted to determine the prevalence of and to identify the predisposing factors for echinococcosis and cysticercosis in sheep and goats at three slaughter slabs located in the livestock-wildlife interface areas of Ngorongoro, Tanzania. Materials and Methods: A cross-sectional based survey was conducted, from January 2013 to April 2013, whereby a total of 180 animals comprising 90 goats and 90 sheep of both sexes were examined at postmortem for the evidence of larval stages of Echinococcus spp. (hydatid cyst and T. hydatigena (Cysticercus tenuicollis through visual inspection, incision and palpation of organs and viscera. Results: The prevalence of echinococcosis was 22.2% and 16.6%, in goats and sheep, respectively, while the overall infection rates for cysticercosis were 61.1% in goats and 42.2% in sheep. The result of this study revealed that goats and sheep in Malambo slaughter slab had significantly higher prevalence of T. hydatigena (C. tenuicollis and hydatid cysts (p<0.05 compared to other slab points. T. hydatigena (C. tenuicollis cysts were more frequently detected in the omentum than other visceral organs among the animals examined. Conclusion: In conclusion, the observed high prevalence of the two metacestodes larval stages leads to high condemnation rates of edible offals and raises significant public health concerns. This underscores for the need to undertake more extensive epidemiological investigations to better determine the causal factors, economic impact, and public health importance of the disease in this livestock-wildlife interface setting.

    The hepatic bridge forms a tunnel of liver parenchyma that may obscure peritoneal metastases associated with the round ligament. Visualization and then resection of nodules associated with this structure is necessary. The incidence of a hepatic bridge and the extent that it covered the round ligament was determined in consecutive patients. Extent of coverage of the round ligament by the hepatic bridge was determined: Class 1 indicates up to one-third of the round ligament obscured, Class 2 up to two-thirds and Class 3 more than two-thirds. In 102 patients in whom the round ligament of the liver could be completely visualized, 50 had a hepatic bridge. Class 1 was 22 (44%) of the bridges, Class 2 was 16 (32%) and Class 3 was 12 (24%). A hepatic bridge was more frequently present in 28 of 45 male patients (62%) vs. 22 of 57 female patients (38%). Approximately one-half of our patients having cytoreductive surgery for peritoneal metastases were observed to have a hepatic bridge. Up to 56% of these patients have Class 2 or 3 hepatic bridge and may require division of the hepatic bridge to completely visualize the contents of the tunnel created by this structure.

    2010-01-01

    The history of viral hepatitis goes back thousands of years and is a fascinating one. When humans were first infected by such agents, a natural repetitive cycle began, with the capacity to infect billions of humans, thus decimating the population and causing sequelae in thousands of lives. This article reviews the available scientific information on the history of viral hepatitis. All the information was obtained through extensive bibliographic review, including original and review articles and consultations on the internet. There are reports on outbreaks of jaundice epidemics in China 5,000 years ago and in Babylon more than 2,500 years ago. The catastrophic history of great jaundice epidemics and pandemics is well known and generally associated with major wars. In the American Civil War, 40,000 cases occurred among Union troops. In 1885, an outbreak of catarrhal jaundice affected 191 workers at the Bremen shipyard (Germany) after vaccination against smallpox. In 1942, 28,585 soldiers became infected with hepatitis after inoculation with the yellow fever vaccine. The number of cases of hepatitis during the Second World War was estimated to be 16 million. Only in the twentieth century were the main agents causing viral hepatitis identified. The hepatitis B virus was the first to be discovered. In this paper, through reviewing the history of major epidemics caused by hepatitis viruses and the history of discovery of these agents, singular peculiarities were revealed. Examples of this include the accidental or chance discovery of the hepatitis B and D viruses.

Modern management strategies for patients with cholestasis are desperately needed. The aim is proof of principle of serial ERC (endoscopic retrograde cholangiography) balloon dilation for AE biliary pathology. Methods Retrospective case series of seven consecutive patients with AE-associated biliary pathology and ERC treatment in an interdisciplinary endoscopy unit at a University Hospital which hosts a national echinococcosis treatment center. The AE patient cohort consists of 106 patients with AE of the liver of which 13 presented with cholestasis. 6/13 received bilio-digestive anastomosis and 7/13 patients were treated by ERC and are reported here. Biliary stricture balloon dilation was performed with 18-Fr balloons at the initial and with 24-Fr balloons at subsequent interventions. If indicated 10 Fr plastic stents were placed. Results Six patients were treated by repeated balloon dilation and stenting, one by stenting only. After an acute phase of 6 months with repeated balloon dilation, three patients showed “sustained clinical success” and four patients “assisted therapeutic success,” of which one has not yet reached the six month endpoint. In one patient, sustained success could not be achieved despite repeated insertion of plastic stents and balloon dilation, but with temporary insertion of a fully covered self-expanding metal stent (FCSEMS). There was no loss to follow up. No major complications were observed. Conclusions Serial endoscopic dilation is a standard tool in the treatment of benign biliary strictures. Serial endoscopic intervention with balloon dilation combined with benzimidazole treatment can re-establish and maintain biliary duct patency in AE associated pathology and probably contributes to avoid or postpone bilio-digestive anastomosis.

    Full Text Available Cystic echinococcosis (CE is a neglected parasitic zoonosis with considerable socioeconomic impact on affected pastoral communities. CE is endemic throughout the Mediterranean, including Morocco, where the Mid Atlas is the most prevalent area for both human and animal infection. The highest hospital annual incidence of human CE is recorded in the provinces of Ifrane and El Hajeb. However, hospital-based statistics likely underestimate the real prevalence of infection, as a proportion of cases never reach medical attention or official records.In 2012, a project on clinical management of CE in Morocco was launched with the aims of estimating the prevalence of human abdominal CE in selected rural communes of the above mentioned provinces using ultrasound (US screening and training local physicians to implement US-based focused assessment and rational clinical management of CE according to the WHO-IWGE Expert Consensus. A total of 5367 people received abdominal US during four campaigns in April-May 2014. During the campaigns, 24 local general practitioners received >24 hours of hands-on training and 143 health education sessions were organized for local communities. We found an overall CE prevalence of 1.9%, with significantly higher values in the rural communes of Ifrane than El Hajeb (2.6% vs 1.3%; p<0.001. CE cysts were predominantly in inactive stage, especially in older age groups. However, active cysts were present also in adults, indicating acquisition of infection at all ages. Province of residence was the only risk factor consistently associated with CE infection.Our results show a high prevalence and on-going, likely environmental transmission of CE in the investigated provinces of Morocco, supporting the implementation of control activities in the area by national health authorities and encouraging the acceptance and divulgation of diagnosis and treatment algorithms based on imaging for CE at both national and local level.

    2017-07-06

    The parasitic disease, cystic echinococcosis (CE), is prevalent in low-income, livestock-raising communities and 2000 new people will be diagnosed this year in South America alone. The disease usually passes from livestock to dogs to humans, making it a zoonotic disease and part of the One Health Initiative. Control of CE has been infamously difficult; no endemic areas of South America have succeeded in maintaining sustainable eradication of the parasite. For the current study, we aimed to gain a better understanding of the knowledge, attitudes, and practices of rural sheep farmers and other community leaders regarding their sheep herding practices and perspectives about a control program for CE. We also hope to identify potential barriers and opportunities that could occur in a control program. The authors conducted Knowledge, Attitude and Practices (KAP) surveys and semi-structured interviews in rural communities in the highlands of Peru. The KAP surveys were administered to 51 local shepherds, and the semi-structured interviews were administered to 40 individuals, including shepherds, community leaders, and health care providers. We found that the shepherds already deworm their sheep at a median of 2 times per year (N = 49, range 2-4) and have a mean willingness-to-pay of U.S. $ 0.60 for dog dewormer medication (N = 20, range = 0.00- $2.00 USD). We were not able to learn the deworming agent or agents that were being used, for neither sheep nor dogs. Additionally, 90% of shepherds slaughter their own sheep (N = 49). We also learned that the main barriers to an effective control program include: lack of education about the cause and control options for CE, accessibility to the distant communities and sparse grazing pastures, and a lack of economic incentive. Findings suggest it may be feasible to develop an effective CE control program which can be used to create an improved protocol to control CE in the region.

  19. Long-term follow-up of metabolic activity in human alveolar echinococcosis using FDG-PET

    Aim: [ 18 F]fluoro-deoxyglucose positron-emission-tomography (FDG-PET) detects metabolic activity in alveolar echinococcosis (AE). The slow changes in metabolic and morphological characteristics require long-term follow-up of patients. This is the first study to evaluate metabolic activity over may years, hereby assessing the utility of FDG-PET for the evaluation of disease progression and response to treatment. Patients, methods: 15 patients received a follow-up FDG-PET combined with computed tomography (integrated PET/CT) with a median of 6.5 years after the first PET in 1999. Number and location of enhanced metabolic activity in the area of AE lesions was determined. Quantification of intensity of metabolic activity was assessed by calculation of mean standardized uptake values. Results: AE lesions in 11/15 patients had been metabolically inactive initially, but only two showed permanent inactivity over the course of 81 months. Interestingly, in two patients metabolic activity was newly detected after 80 and 82 months. Benzimidazole treatment was intermittently discontinued in seven cases. Persisting activity at FDG-PET demanded continued benzimidazole treatment in four patients. Neither treatment duration, lesional size, calcifications nor regressive changes correlated with metabolic activity. Conclusion: treatment responses are heterogeneous and vary from progressive disease despite treatment to long-term inactive disease with discontinued treatment. Lack of metabolic activity indicates suppressed parasite activity and is not equivalent to parasite death. However, metabolic activity may remain suppressed for years, allowing for temporary treatment discontinuation. Relapses are reliably detected with PET and restarting benzimidazole treatment prevents parasite expansion. (orig.)

  20. Screening of the Open Source Malaria Box Reveals an Early Lead Compound for the Treatment of Alveolar Echinococcosis.

    2016-03-01

    Full Text Available The metacestode (larval stage of the tapeworm Echinococcus multilocularis causes alveolar echinococcosis (AE, a very severe and in many cases incurable disease. To date, benzimidazoles such as albendazole and mebendazole are the only approved chemotherapeutical treatment options. Benzimidazoles inhibit metacestode proliferation, but do not act parasiticidal. Thus, benzimidazoles have to be taken a lifelong, can cause adverse side effects such as hepatotoxicity, and are ineffective in some patients. We here describe a newly developed screening cascade for the evaluation of the in vitro efficacy of new compounds that includes assessment of parasiticidal activity. The Malaria Box from Medicines for Malaria Venture (MMV, comprised of 400 commercially available chemicals that show in vitro activity against Plasmodium falciparum, was repurposed. Primary screening was carried out at 10 μM by employing the previously described PGI assay, and resulted in the identification of 24 compounds that caused physical damage in metacestodes. Seven out of these 24 drugs were also active at 1 μM. Dose-response assays revealed that only 2 compounds, namely MMV665807 and MMV665794, exhibited an EC50 value below 5 μM. Assessments using human foreskin fibroblasts and Reuber rat hepatoma cells showed that the salicylanilide MMV665807 was less toxic for these two mammalian cell lines than for metacestodes. The parasiticidal activity of MMV665807 was then confirmed using isolated germinal layer cell cultures as well as metacestode vesicles by employing viability assays, and its effect on metacestodes was morphologically evaluated by electron microscopy. However, both oral and intraperitoneal application of MMV665807 to mice experimentally infected with E. multilocularis metacestodes did not result in any reduction of the parasite load.

    Both cysticercosis and echinococcosis are potentially among the most serious helminth zoonoses threatening human health worldwide. However, due to the lack of reliable tools for confirmation or identification of patients or infected animals, epidemiological data are expected to be underestimated. Conversely, sometimes, such data are over estimated due to the lack of specificity. The most important issue for doing field surveys is that they use evidence based science. In this communication, advanced immunological and molecular tools for detection of individuals infected with either metacestodes or adult tapeworms are briefly overviewed, and the applications of such tools for epidemiological surveys in Indonesia, China and other countries are introduced. As immunological tools are based on antigen-antibody responses, there may exist some cross-reactions. Therefore, immunodiagnostic tools are expected to be useful for primary screening, and should be combined with confirmation of direct parasitological evidence (morphology or DNA), and imaging techniques for cysts. As a risk factor for human cysticercosis is the presence of tapeworm carriers, detection of taeniasis cases and differentiation of the three human Taenia species (Taenia solium, T. saginata and T. asiatica) in Asia and the Pacific requires consideration. Similarly, in northwest China, Echinococcus granulosus and E. multilocularis are coendemic and differentiation of these species is required in humans and definitive hosts. It is stressed that combination of several tools for identification of the parasite and for confirmation of diseases is important for obtaining highly reliable data before consideration of control of these zoonoses. Recent projects coordinated by Asahikawa Medical College have concentrated on immunological and molecular diagnostic techniques transferable to colleagues from endemic regions of Asia and the Pacific, and on organization of two international symposia to establish a platform

    Trichinellosis and cystic and alveolar echinococcosis are serious parasitic diseases transmissible between animals and humans. Moreover, alveolar echinococcosis is considered one of the most dangerous of human helminthoses. Roma communities are particularly numerous in Central and Eastern Europe. They are often concentrated in economically undeveloped regions and live in segregated localities with unsatisfactory housing and sanitary conditions. The study aimed to find out the seroprevalence of Trichinella and Echinococcus infections in the Roma population of segregated settlements and to compare it with the seropositivity of the non-Roma population of eastern Slovakia. Out of 823 samples, three sera showed seropositivity to Trichinella in the ELISA (Enzyme-linked immunosorbent assay) test. Subsequent Western blot reaction (WB) confirmed seropositivity in two Roma women. ELISA seropositivity to E. multilocularis was recorded in six persons (0.73%), and five (0.61%) respondents were seropositive to E. granulosus , but WB confirmed the presence of antibodies to Echinococcus spp. in one Roma participant. Positive persons suffered from unspecific clinical symptoms; Trichinella -positive persons reported headache, cough, fatigue, and muscle pain. The Echinococcus -positive participant suffered from headache and back pain. The study showed that the worse living conditions of the Roma community did not significantly influence the occurrence of Trichinella and Echinococcus infections in this minority.

    Diagnosis of cystic echinococcosis (CE) is at present mainly based on imaging techniques. Serology has a complementary role, partly due to the small number of standardized and commercially available assays. Therefore we examined the clinical performance of the SERION ELISA classic Echinococcus IgG test. Using 10 U/ml as a cut-off point, and serum samples from 50 CE patients and 105 healthy controls, the sensitivity and specificity were 98.0% and 96.2%, respectively. If patients with other infectious diseases were used as negative controls, the specificity decreased to 76.9%, which causes poor positive predictive values. However, if results between 10 and 15 U/ml are classified as indecisive, the specificity of positive results (≥15 U/ml) increased to 92.5% without greatly affecting the sensitivity (92.0%). Using this approach in combination with imaging studies, the SERION ELISA classic Echinococcosis IgG test can be a useful aid in the diagnosis of CE.

    2017-05-01

    Feline hepatic lipidosis (FHL) is a common and potentially fatal liver disorder. Although the pathophysiologic mechanisms of FHL remain elusive, there is an imbalance between the influx of fatty acids from peripheral fat stores into the liver, de novo liposynthesis, and the rate of hepatic oxidation and dispersal of hepatic TAG via excretion of very-low density lipoproteins. The diagnosis of FHL is based on anamnestic, clinical, and clinicopathologic findings, associated with diagnostic imaging of the liver, and cytology, or histological examination of liver biopsies. Fluid therapy, electrolyte correction and adequate early nutrition are essential components of the therapy for FHL. Copyright © 2016 Elsevier Inc. All rights reserved.

    The detection of diagnostic autoantibodies such as antinuclear antibodies (ANA), anti-smooth muscle antibodies (SMA), anti-liver/kidney microsomal type 1 (anti-LKM1), anti-liver cytosol type 1 (anti-LC1) and anti-soluble liver antigen (anti-SLA) is historically associated with the diagnosis of autoimmune hepatitis. When autoimmune hepatitis is suspected, the detection of one or any combination of diagnostic autoantibodies, by indirect immunofluorescence or immuno-enzymatic techniques with recombinant antigens, is a pivotal step to reach a diagnostic score of probable or definite autoimmune hepatitis. Diagnostic autoantibodies (ANA, SMA, anti-LKM1, anti-LC1, anti-SLA) are a cornerstone in the diagnosis of autoimmune hepatitis. Other ancillary autoantibodies, associated with peculiar clinical correlations, appear to be assay-dependent and institution-specific, and validation studies are needed. © 2015 S. Karger AG, Basel.

    The diagnosis of hepatic rupture in patients with pregnancy-induced hypertension (preeclampsia and eclampsia) is rarely made preoperatively. Diagnostic imaging can be utilized in some patients to confirm the preoperative diagnosis. Since hematoma formation precedes hepatic rupture, then, when diagnostic modalities such as sonography and computed tomography identify patients with hematomas, these patients are at risk of rupture, and should be hospitalized until the hematomas resolve

The disease can be considered primary or idiopathic when its underlying cause is unknown, or secondary when there is another concomitant disease lipidosis. Cats with hepatic lipidosis have anorexia usually ranging from several days to weeks and weight loss, followed by jaundice and varying degrees of dehydration, diarrhea and vomiting episodes may occur. A worsening of the disease shows signs of hepatic encephalopathy, drooling and retroflexion of the neck. In clinical examination can be observed depression, lethargy and hepatomegaly. The definitive diagnosis of the disease can be performed by fine needle aspiration biopsy guided by ultrasound and cytology or biopsy. The treatment of hepatic lipidosis is based on stabilizing the patient by supplying water and electrolyte losses and provide adequate nutritional support. The diet is usually provided through feeding tubes for a period ranging from 4 to 6 weeks may occur depending on the patient's condition. The prognosis for cats with hepatic lipidosis is favored in cases of identification followed by intensive treatment of underlying causes and for patients receiving therapy necessary in cases of idiopathic hepatic lipidosis.

  10. MHC-DQB1 Variation and Its Association with Resistance or Susceptibility to Cystic Echinococcosis in Chinese Merino Sheep

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available Cystic echinococcosis (CE, one of the world’s most geographically widespread diseases, still represents a considerable economic and public health significance, although a variety of methods has been used to control the disease. It has been demonstrated that genetic factors, especially variations in MHC loci, can influence the outcome of CE infection in the human population. The study described here was designed to determine whether variation in MHC-DQB1 was associated with susceptibility or resistance to CE in sheep. If so, it would lay a theoretical foundation for breeding disease resistance sheep in future. This study was carried out on 204 Chinese Merino sheep, including 101 CE sheep and 103 healthy controls. The polymorphism of MHC-DQB1 exon 2 was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP method, and x2 test was used to compare genotype frequencies between CE sheep and healthy controls. A total of 22 alleles and 42 genotypes were identified in DQB1 exon 2 in Chinese Merino sheep. In addition, x2 test showed that frequencies of DQB1-TaqIaa and DQB1-HaeIIInn genotypes were significantly higher in the healthy group (82.5% and 57.3%, respectively than that in the CE group (57.4% and 28.9%, respectively (both p values = 0, OR = 0.286, 0.303, respectively, suggesting that these genotypes appeared to be associated with resistance to CE. Whereas, frequencies of DQB1-TaqIab and DQB1-HaeIIImn genotypes were significantly higher in the CE group (36.9% and 32.0%, respectively, as compared with the healthy group (16.5% and 11.15%, respectively (p = 0.001, 0.001 and OR = 2.963, 3.629, respectively, indicating that these genotypes might be associated with susceptibility to CE. It is concluded that the genetic polymorphism within MHC-DQB1 might influence immune responses to pathogens, thus leading to the development of CE or protection against CE in Chinese Merino sheep, which would pave the way for breeding

    2013-01-01

    Hepatic encephalopathy has been listed as a differential for llamas displaying neurologic signs, but it has not been histopathologically described. This report details the neurologic histopathologic findings associated with 3 cases of hepatic lipidosis with concurrent neurologic signs and compares them to 3 cases of hepatic lipidosis in the absence of neurologic signs and 3 cases without hepatic lipidosis. Brain from all 3 llamas displaying neurologic signs contained Alzheimer type II cells, which were not detected in either subset of llamas without neurologic signs. Astrocytic immunohistochemical staining intensity for glial fibrillary acid protein was decreased in llamas with neurologic signs as compared to 2 of 3 llamas with hepatic lipidosis and without neurologic signs and to 2 of 3 llamas without hepatic lipidosis. Immunohistochemical staining for S100 did not vary between groups. These findings suggest that hepatic encephalopathy may be associated with hepatic lipidosis in llamas.

  17. Primary hepatic artery embolization in pediatric blunt hepatic trauma.

    Ong, Caroline C P; Toh, Luke; Lo, Richard H G; Yap, Te-Lu; Narasimhan, Kannan

    2012-12-01

    Non-operative management of isolated blunt hepatic trauma is recommended except when hemodynamic instability requires immediate laparotomy. Hepatic artery angioembolization is increasingly used for hepatic injuries with ongoing bleeding as demonstrated by contrast extravasation on the CT scan. It is used primarily or after laparotomy to control ongoing hemorrhage. Hepatic angioembolization as part of multimodality management of hepatic trauma is reported mainly in adults, with few pediatric case reports. We describe our institution experience with primary pediatric hepatic angioembolization and review the literature with regard to indications and complications. Two cases (3 and 8 years old), with high-grade blunt hepatic injuries with contrast extravasation on the CT scan were successfully managed by emergency primary hepatic angioembolization with minimal morbidity and avoided laparotomy. To date, the only reports of pediatric hepatic angioembolization for trauma are 5 cases for acute bleeding and 15 delayed cases for pseudoaneurysm. The role of hepatic angioembolization in the presence of an arterial blush on CT in adults is accepted, but contested in a pediatric series, despite higher transfusion rate and mortality rate. We propose that hepatic angioembolization should be considered adjunct treatment, in lieu of, or in addition to emergency laparotomy for hemostasis in pediatric blunt hepatic injury.

    Pheochromocytomas are uncommon tumors that represent a potentially curable cause of hypertension. They are usually located in the adrenal glands, but 10% arise from extra-adrenal sites, located along the paravertebral sympathetic chains. We report a case of primary hepatic pheochromocytoma responsible for a severe hypertension in a 24-year-old man. Echotomography showed a lightly heterogeneous mass located in the segment 8 of the liver. Iodine 131 -metaiodobenzylguanidine scintigraphy showed a large hepatic concentration of the tracer and no other localization. This tumor appeared highly vascularized on enhanced CT scan and on aortic angiography. Magnetic resonance imaging revealed a hepatic tumor with a high signal intensity on T2-weighted images and with a signal isointense to the liver on T1-weighted images. The hepatic venous sampling contained the highest catecholamine level, whereas the adrenal venous samping was normal. After surgical resection of the hepatic tumor, the tension level and catecholamines plasmatic level normalized. No recurrent symptoms appeared during a 3-year follow-up. (orig.)

    Full Text Available Hepatitis B (Hepatitis B is a hepatitis B virus (HBV -based liver disease. This virus has an affinity for liver cells, it can cause both acute and chronic viral infections of varying severity. The consequences of chronic HBV infection can be cirrhosis and liver cancer. In Poland in 1989 a preventive program was implemented to reduce HBV infection. Universal vaccinations have been introduced to reduce the prevalence of Type B hepatitis B from 40.3 / 100,000 in 1989 to 7/100 in 2000. In the last 20 years in Poland there has been huge progress in the prevention and suppression of HBV infections. Decrease in the incidence of hepatitis B is mainly the result of the introduction of compulsory vaccination and improving hygiene procedures and improve sanitation aimed at aborting the pathways of the virus. However, still a large part of society is not immune on HBV infection acting potential group of the risk of infection. In addition, in the era of a growing group of followers. movements of the anti vaccine it is necessary to continue to promote knowledge of HBV and the efficacy and safety of vaccination.

    Excess alcohol consumption can worsen the course and outcome of chronic hepatitis C. It is important to distinguish between alcohol abuse, which must be treated on its own merits, and the effect of alcohol use on progression, severity, and treatment of hepatitis C. Most studies on the effects of alcohol on hepatitis C have focused on patients, with high levels of daily alcohol intake. Indeed, the adverse effects of light and moderate amounts of alcohol intake on hepatitis C virus (HCV) infect...

  7. Hepatic angiography: Portal hypertension

    International Nuclear Information System (INIS)

    Oliver, T.W. Jr.; Sones, P.J. Jr.

    1985-01-01

    Portal hypertension is usually a manifestation of underlying hepatic parenchymal disease, although it may be secondary to portal or hepatic venous thrombosis and rarely to hyperdynamic portal states. Portal hypertension may present as encephalopathy, ascites, jaundice, hepatic failure, or catastrophic upper gastrointestinal hemorrhage. Radiologic investigation should include indirect or direct measurements of portal pressure, assessment of portal venous perfusion, visualization of collaterals, and demonstration of arterial and venous anatomy for potential shunt procedure. Following survival of initial variceal bleeding, the most effective procedure to prevent recurrent hemorrhage is a shunt to decompress the varices. The decision whether to intervene medically or surgically during the acute hemorrhagic episode as well as the type of shunt used to prevent future hemorrhage is the subject of continuing controversy

  8. Prophylactic Hepatitis E Vaccine.

    Zhang, Jun; Zhao, Qinjian; Xia, Ningshao

    2016-01-01

    Hepatitis E has been increasingly recognized as an underestimated global disease burden in recent years. Subpopulations with more serious infection-associated damage or death include pregnant women, patients with basic liver diseases, and elderly persons. Vaccine would be the most effective means for prevention of HEV infection. The lack of an efficient cell culture system for HEV makes the development of classic inactive or attenuated vaccine infeasible. Hence, the recombinant vaccine approaches are explored deeply. The neutralizing sites are located almost exclusively in the capsid protein, pORF2, of the virion. Based on pORF2, many vaccine candidates showed potential of protecting primate animals; two of them were tested in human and evidenced to be well tolerated in adults and highly efficacious in preventing hepatitis E. The world's first hepatitis E vaccine, Hecolin ® (HEV 239 vaccine), was licensed in China and launched in 2012.

    2011-01-01

    The hepatitis E virus (HEV) the causative agent of hepatitis E, is a non-enveloped RNA virus. HEV is transmitted through oral consumption of contaminated food and water According to the currently knowledge now be considered as zoonosis. The main reservoir of HEV are pigs, boars and deer. For the first time HEV was isolated from animals (pigs) in 1997 in the U.S. Genetic analysis of strains isolated from pigs showed high similarity to strains HEV isolated from humans. This was the first evidence showing that HEV is a zoonosis. Further studies have shown that occupational groups e.g. veterinarians, swine breeders with close contact to pigs have an increased risk for HEV infections. The additional evidence supported the zoonotic potential of HEV were reports of acute hepatitis E after the consumption of undercooked meat from deer and wild boar. Infection of HEV in the domestic pig and wild boar population in Europe is widespread.

    The hepatic artery aneurysms are rare, especially in interahepatic branches, The frequency consists of 75-80% extrahepatic and 20-25% intrahepatic. Catheterization is achieved usually from common femoral artery, other methods implemented in the case of unsuccessful catheterization from femoral artery, are translumbar and brachial catheterization. The study consist of 565 patients that were referred to the angiography ward, During seven years of assessment, five cases of hepatic artery aneurysm were found; this is a rare condition reported in the English literature. In the literature as well as in this case report the hepatic artery aneurysms are rare. In reported series the extrahepatic artery aneurysms are found more often than in the intrahepatic artery aneurysm but in this case report intrahepatic artery aneurysms are more than extrahepatic one.

The subjects who had liver lesion or hepatic vascular abnormalities were excluded. Couinaud classified accessory hepatic veins into inferior and middle right hepatic veins. Our major interests were evaluation of the incidence, morphology, and location of the accessory hepatic vein. Inferior right hepatic vein was demonstrated in 43 out of 87 patients (49%). The morphology was linear in 35 patients (80.5%), and V-shaped in 8 patients (19.5%). In 40 patients (93%), the inferior right hepatic vein was located in the posteroinferior aspect of the right lobe. Middle right hepatic vein was demonstrated in 7 out of 87 patients (8%). All were single linear in morphology, combined with the inferior right hepatic vein, and located between the right hepatic vein and inferior right hepatic vein. The accessory hepatic vein was demonstrated in 49% among the Korean adult population, and was located in posteroinferior portion of the liver, in 93%

    To compare the ABZ and its metabolites concentration in cyst tissue of hepatic alveolar echinococcosis administered by different routes, forty male Wistar rats receiving albendazole nanoparticles from tail vein and portal vein were divided into two groups, the concentration of ABZ and its metabolites ABZSO, ABZSO2, in the cyst tissue, were analyzed by HPLC at 2, 4, 8, 24, 36 h after administration. The parent drug and its metabolites were detected in plasm and the cyst tissue after portal cannulation and intravenous administration. The last results were the concentration of ABZ in the portal cannulation group was higher than in the intravenous group at every time point (p < 0.05). Compared to the intravenous group, the portal cannulation administration of ABZ led to a lower plasm concentration of ABZ. The concentration of ABZ and the active ABZSO were significantly higher in the portal cannulation group than that of the intravenous group. Copyright © 2015 Elsevier Inc. All rights reserved.

    2012-01-01

    Full Text Available UNLABELLED: Cystic echinococcosis (CE is a chronic, complex and neglected disease caused by the larval stage of Echinococcus granulosus. The effects of this neglect have a stronger impact in remote rural areas whose inhabitants have no chances of being diagnosed and treated properly without leaving their jobs and travelling long distances, sometimes taking days to reach the closest referral center. BACKGROUND: In 1980 our group set up a control program in endemic regions with CE in rural sections of Rio Negro, Argentina. Since 1997, we have used abdominopelvic ultrasound (US as a screening method of CE in school children and determined an algorithm of treatment. OBJECTIVES: To describe the training system of general practitioners in early diagnosis and treatment of CE and to evaluate the impact of the implementation of the field program. MATERIALS AND METHODS: In 2000, to overcome the shortage of radiologists in the area, we set up a short training course on Focused Assessment with Sonography for Echinococcosis (FASE for general practitioners with no previous experience with US. After the course, the trainees were able to carry out autonomous ultrasound surveys under the supervision of the course faculty. From 2000 to 2008, trainees carried out 22,793 ultrasound scans in children from 6 to 14 years of age, and diagnosed 87 (0.4% new cases of CE. Forty-nine (56.4% were treated with albendazole, 29 (33.3% were monitored expectantly and 9 (10.3% were treated with surgery. DISCUSSION: The introduction of a FASE course for general practitioners allowed for the screening of CE in a large population of individuals in remote endemic areas with persistent levels of transmission, thus overcoming the barrier of the great distance from tertiary care facilities. The ability of local practitioners to screen for CE using US saved the local residents costly travel time and missed work and proved to be an efficacious and least expensive intervention tool for

    Objective: To investigate the correlationship between blood hepatic fibrosis markers and blood lipids levels. Methods: Serum hepatic fibrosis markers (HA, PC III, IV-C, LN) levels were determined with RIA and serum lipids (TG, TCh HDL; LDL, apoA1, apoB) were measured with biochemical methods in 98 patients with hepatitis in various stages and 50 controls. Liver biopsy was done in all the hepatitis patients. Results: Hepatic fibrosis was classified into 5 grades (S0-S4) according to the pathology shown in the biopsy specimen. The serum lipid levels decreased along with the increase of severity of fibrosis from S0 to S4. Levels in S4 patients were significantly lower than those in controls (P 0.05). Conclusion: The serum hepatic fibrosis markers levels increased and lipids levels decreased along with the progress of hepatitis from acute to cirrhosis. (authors)

  18. Echinococcus granulosus infection and options for control of cystic echinococcosis in Tibetan communities of Western Sichuan Province, China.

    Directory of Open Access Journals (Sweden)

    Yu Rong Yang

    Full Text Available BACKGROUND: Human cystic echinococcosis (CE is highly endemic in the Tibetan regions of Sichuan where most families keep guard dogs and where there are considerable numbers of ownerless/stray dogs. Strong Buddhist beliefs do not allow for elimination of stray dogs, and many strays are actually fed and adopted by households or monasteries. On account of the high altitude (3900-5000 m, pasturage is the major agricultural activity in this area. The harsh mountainous climate often leads to many grazing animals dying on the pasture at the end of a hard winter. The skin and some meat are taken, and the rest of the animal is left for scavenging birds and animals. The poor sanitation and hygiene, the Buddhist doctrine of allowing old livestock to die naturally, plus the unrestricted disposal of animal viscera post-slaughter may be responsible for the high prevalence of human CE in this setting. METHODS AND FINDINGS: As part of a large collaborative control program for CE in Ganzi County, situated in the west of Sichuan Province, surveillance for Echinococcus infection in domestic dogs using a coproantigen method and necropsy of unwanted dogs was carried out prior to (in 2000 and after (in 2005 dog anthelminthic treatment (5 mg/kg oral praziquantal at 6 month intervals to determine the efficacy of the treatment for control. The prevalence of E. granulosus only in dogs by necropsy was 27% and 22%, and prevalence of both Echinococcus spp. by necropsy was 63% and 38%; prevalence of both Echinococcus spp. by coproantigen analysis was 50% and 17%. Necropsy of sheep/goats (age <1 to 12 years (prevalence of E. granulosus in 1-6-year-old animals was 38% and in 10-12-year-old animals was 70% and yaks (age 4 years (prevalence of E. granulosus was 38% was undertaken to determine the baseline transmission pressure. Protoscoleces were only found in very old sheep/goats and yaks. Necropsy of dogs in the Datangma district indicated that there was no apparent

    2017-04-01

    Full Text Available Congenital hepatic cyst is a rare and nonsymptomatic condition in infants and children. Its incidence is 2.5% in the postnatal life with a much lower incidence in the prenatal period. Incidental finding on antenatal imaging is the most common presentation. We present a case of a newborn in whom fetal ultrasound detected a cyst within the fetal liver. Postnatal imaging revealed a liver cyst in the right lobe of the liver, with no other intrahepatic structure affected. Liver function tests were abnormal, but the patient was asymptomatic. Posterior follow-up imaging showed a minor decrease in size. Management of congenital hepatic cyst is usually conservative, done with periodic ultrasound monitoring. However, surgical treatment is the mainstay of treatment when hydrops, progressive enlargement, hemorrhage, torsion, or compression of adjacent structures occurs. Malignant transformation can occur, but it is extremely rare. Partial or total removal of the cyst is the preferred treatment in neonates with a large lesion.

    Two flocks of 14,000 twenty-week-old turkey hens each experienced increased mortality due to hepatic lipidosis. Some hens showed signs of dyspnea and cyanosis before death. Necropsy revealed dark muscles and enlarged livers with pale areas and numerous hemorrhages. Petechial and ecchymotic hemorrhages were also found on the abdominal fat and epicardium. Lung congestion and edema were prominent. In the heart and blood vessels, the blood was uncoagulated. Mortality was elevated for 12 days and resulted in the death of 0.7% of the turkey hens in one flock and 1.7% in the other. Vitamin E administered in water at a dose of 25 IU per hen appeared to reduce mortality. The nutritional and environmental factors that may contribute to the development of hepatic lipidosis in turkeys are discussed.

    1995-03-01

    Feline IHL is a severe hepatopathy that can be treated by aggressive nutritional support. Until the underlying mechanisms of protein and lipid metabolism are understood in both healthy and ill cats, dietary therapy remains supportive. It is likely that the pathogenesis of IHL in cats is multifactorial, involving both increased fatty acid mobilization to the liver and a defect in oxidation of fatty acids or removal of VLDL. It is also possible that individual variation may play a role in the development of this disease in cats undergoing starvation. Continued studies will focus on the unique pathways of hepatic metabolism in the cat, and how these pathways are altered, leading to hepatic lipid accumulation and clinical disease. Hopefully, these studies can be applied to the prevention or treatment of IHL in cats.

    1983-01-01

    Twenty-five patients with hepatic injury from blunt upper abdominal trauma were examined by computed tomography (CT). The spectrum of CT findings was recorded, and the size of the hepatic laceration and the associated hemoperitoneum were correlated with the mode of therapy used in each case (operative vs nonoperative). While the need for surgery correlated roughly with the size of the hepatic laceration, the size of the associated hemoperitoneum was an important modifying factor. Fifteen patients with hepatic lacerations but little or no hemoperitoneum were managed nonoperatively. CT seems to have significant advantages over hepatic scintigraphy, angiography, and diagnostic peritoneal lavage. By combining inforamtion on the clinical state of the patient and CT findings, therapy of hepatic injury can be individualized and the incidence of nontherapeutic laparotomies decreased

    Autoimmune hepatopathies (AIHT) including autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and autoimmune cholangitis (AIC), represent an impressive entities in clinical practice. Their pathogenesis is not perfectly elucidated. Several factors are involved in the initiation of hepatic autoimmune and inflammatory phenomena such as genetic predisposition, molecular mimicry and/or abnormalities of T-regulatory lymphocytes. AIHT have a wide spectrum of presentation, ranging from asymptomatic forms to severe acute liver failure. The diagnosis of AIHT is based on the presence of hyperglobulinemia, cytolysis, cholestasis, typical even specific circulating auto-antibodies, distinctive of AIH or PBC, and histological abnormalities as well as necrosis and inflammation. Anti-F actin, anti-LKM1, anti-LC1 antibodies permit to distinguish between AIH type 1 and AIH type 2. Anti-SLA/LP antibodies are rather associated to more severe hepatitis, and particularly useful for the diagnosis of seronegative AIH for other the antibodies. Due to the relevant diagnostic value of anti-M2, anti-Sp100, and anti-gp210 antibodies, the diagnosis of PBC is more affordable than that of PSC and AIC. Based on clinical data, the immunological diagnosis of AIHT takes advantage of the various specialized laboratory techniques including immunofluorescence, immunodot or blot, and the Elisa systems, provided of a closer collaboration between the biologist and the physician.

    Full Text Available Objectives : Epidemiologic data of HIV and viral hepatitis coinfection are needed in sub-Saharan Africa to guide health policy for hepatitis screening and optimized antiretroviral therapy (ART. Materials and Methods: We screened 323 HIV-infected, ART-eligible adults for hepatitis B surface antigen (HBsAg and hepatitis C antibody (HCV Ab at a tertiary hospital in Lusaka, Zambia. We collected basic demographic, medical, and laboratory data to determine predictors for coinfection. Results: Of 323 enrolled patients, 32 (9.9%; 95% CI=6.7-13.2% were HBsAg positive, while 4 (1.2%; 95% CI=0.03-2.4% were HCV Ab positive. Patients with hepatitis B coinfection were more likely to be 200 IU/L was uncommon and did not differ between the two groups (3.4% vs. 2.3%; P=0.5. We were unable to determine predictors of hepatitis C infection due to the low prevalence of disease. Conclusions: HIV and hepatitis B coinfection was common among patients initiating ART at this tertiary care facility. Routine screening for hepatitis B should be considered for HIV-infected persons in southern Africa.

    2017-05-01

    Hepatic lipodystrophy in Galloway calves is a fatal liver disease affecting a small proportion of the Galloway breed described in different parts of Europe and North America during the past decades. The clinical findings include a diversity of neurological signs. Clinical pathology findings frequently indicate hepatobiliary disease. Postmortem examination reveals an enlarged, pale yellow, and firm liver. Histologic lesions include hepatic fibrosis, hepatic lipidosis, and bile duct hyperplasia. To date, the etiopathogenesis remains obscure. Infectious causes, intoxications, and a hereditary origin have been considered. We describe hepatic lipodystrophy in Galloway calves from an extensively farmed cow-calf operation in southern Germany. Main clinical findings in 6 calves were consistent with hepatic encephalopathy. Clinical pathology findings in 5 of 6 tested animals revealed increased concentration of total bilirubin (maximum value [MV], 54 μmol/l; reference range [RR], 250 U/g Hb). Postmortem examination in 6 calves revealed a firm, diffusely enlarged yellow liver with a finely nodular surface. Histologic lesions included hepatic fibrosis, hepatic lipidosis, and bile duct hyperplasia. Our findings add to the existing data on hepatic lipodystrophy in the Galloway breed and outline a protocol to aid in the diagnosis of this disorder.

  9. Autoimmune hepatitis vs. pregnancy

    Directory of Open Access Journals (Sweden)

    2017-07-01

    Full Text Available Introduction Autoimmune hepatitis (AIH is a disease of unknown etiology. In pregnancy, it may have mild clinical course as well as can lead to liver failure, or exacerbation of clinical symptoms. In pregnant women the severity of symptoms is often observed between the second and third trimester, and in the puerperium. The disease is marked by enhanced activity of Th lymphocytes, which hepatocytes recognize as foreign antigens. This results in interleukin production activating B lymphocytes, and the production of specific antibodies attacking and destroying the hepatocytes. Case report A 35-year old patient, CII PII, 7 Hbd, with autoimmune hepatitis reported for a check-up. Her first pregnancy was 18 years ago, without history of underlying disease, carried to term without complications. The woman gave birth to a baby-son weighing 3,280g, 10 points Apgar. The delivery was spontaneous and uneventful. The patient got pregnant after an 18-year break. When she twice-tested positively for pregnancy, the treatment with azathioprine was switched to prednisolone. Over the pregnancy the patient was hospitalized 4 times, in 25, 29, 35, and 37 week of gestation due to a threat of preterm delivery, and pregnancy-related cholestasis associated with AIH. In 37 week of gestation, delivery was induced, and she gave birth to a healthy male, weighing 2,650 g, body height of 49 cm, 10 points Apgar scale. The liver function improved and stabilized after the delivery. Treatment with prednisolone has been continued, and the patient’s condition is still controlled. Pregnant patients with autoimmune hepatitis often experience exacerbation of the disease, especially in the third trimester, and in the postpartum period. This case shows that with proper care it is possible to continue and terminate pregnancy safely for the mother and her newly born baby.

    2016-08-01

    Alcoholic hepatitis (AH) causes great morbidity and mortality in the United States and throughout the world. Advances in therapy have proven difficult. In part, this reflects challenges in diagnosis, including the distinction between AH and acute-on-chronic liver failure. Liver biopsy is the best method to clarify the cause in circumstances whereby conflicting clinical data confound the diagnosis. All treatment of AH begins with abstinence from alcohol. All patients with AH should be given sufficient nutrition. Prednisolone has become the principal agent for treating patients with severe AH. Copyright © 2016 Elsevier Inc. All rights reserved.

    Five cases of iterative liver resections are presented, out of a total of 150 hepatectomies performed between 1.01.1995-1.01.1998. The resections were carried out for recurrent adenoma (one case), cholangiocarcinoma (two cases), hepatocellular carcinoma (one case), colo-rectal cancer metastasis (one case). Only cases with at least one major hepatic resection were included. Re-resections were more difficult than the primary resection due, first of all, to the modified vascular anatomy. Intraoperative ultrasound permitted localization of intrahepatic recurrences. Iterative liver resection appears to be the best therapeutical choice for patients with recurrent liver tumors.

    AbstractLatin America is among the highly endemic regions for cystic echinococcosis (CE). In Peru, an estimated 1,139 disability-adjusted life years are lost annually from surgical treatment of CE. This is comparable with the combined total for Argentina, Brazil, Uruguay, and Chile. The prevalence of human infection has been investigated in the central Peruvian Andes, but there are no community-based screening data from other regions of Peru. We carried out a population survey in January 2015 using abdominal ultrasound to estimate the prevalence of abdominal CE in the Canas and Canchis provinces, in the Cusco region of Peru. Among 1,351 subjects screened, 41 (3%) had CE. There was significant variation between communities with similar socioeconomic features in a small geographical area. A history of CE was reported by 4.1% of the screened subjects, among whom 30.3% still had CE on ultrasound. Among patients reporting previous CE treatment, 14.9% had CE in active stages. Limited education, community of residence, and knowing people with CE in the community were associated with CE. These results demonstrate a significant burden of CE in the region and suggest the need for further investigations, control activities, and optimization of clinical management for CE in this area.

    Cystic echinococcosis is one of the most important zoonotic diseases affecting humans and livestock worldwide, and is endemic in Poland. A set of six isolates on larval stages of Echinococcus granulosus sensu lato tapeworms collected from three humans, two pigs and one sheep from Polish foci of CE was examined by DNA sequencing of two mitochondrial genes (cox1, rrnS). The results demonstrated the presence of E. canadensis and E. granulosus sensu stricto in the investigated hydatid cysts. The former species was found in all five isolates from pigs and humans derived from central Poland. In a sheep hydatid cyst originating from Lesser Poland Voivodeship in southern Poland, E. granulosus s. s. (G1 genotype) was identified. This is the first report of an unambiguously autochthonous infection with E. granulosus s. s. in Poland. The global distribution and host affiliations of the commonly occurring G1 microvariant with nucleotide change 56C/T in cox1, detected here in Polish sheep, are discussed. The finding that sheep harboured E. granulosus s. s. may have important consequences for developing effective hydatid control programmes in Poland due to its longer maturation rate in dogs compared with E. canadensis G7. This may lead to greater expenditures for purchasing anthelmintics to provide an appropriate dosing regime in sheep-raising areas of the country.

    Echinococcus multilocularis is a parasite that causes highly pathogenic zoonoses and is maintained in foxes and rodents on Hokkaido Island, Japan. Detection of E. multilocularis infections in swine is epidemiologically important. In Hokkaido, administrative information is provided to swine producers based on the results of meat inspections. However, as the current criteria for providing administrative information often results in delays in providing information to producers, novel criteria are needed. Time series models were developed to monitor autocorrelations between data and lags using data collected from 84 producers at the Higashi-Mokoto Meat Inspection Center between April 2003 and November 2015. The two criteria were quantitatively compared using the sign test for the ability to rapidly detect farm-level outbreaks. Overall, the time series models based on an autoexponentially regressed zero-inflated negative binomial distribution with 60th percentile cumulative distribution function of the model detected outbreaks earlier more frequently than the current criteria (90.5%, 276/305, ppart model with autoexponential regression can adequately deal with data involving an excessive number of zeros and that the novel criteria overcome disadvantages of the current criteria to provide an earlier indication of increases in the rate of echinococcosis.

    Cystic echinococcosis (CE) is a zoonotic disease of humans with variable clinical manifestations. Imaging and immunological methods are currently the mainstay of diagnosis of this disease. Although the immunological tests for detection of anti-echinococcal antibodies have several disadvantages, they are widely being used. Antigen is far more superior than antibody detection test as they can provide a specific parasitic diagnosis. A sandwich enzyme linked immunosorbent assay (ELISA) was designed using antibodies to 24 kDa urinary hydatid antigen for the detection of hydatid antigens in urine, serum and cyst fluid specimens. The performance of this novel test was compared with that of other hydatid antibody detection ELISA and enzyme immune transfer blot (EITB) using radiological and surgical confirmation as the gold standard. The antigen detection ELISA showed 100% sensitivity and specificity when tested with cyst fluid. On testing urine and serum, the antigen detection ELISA was found to be more specific than antibody detection ELISA. EITB was found to be the most sensitive and specific test. ELISA using polyclonal antibodies against 24 kDa urinary hydatid protein was moderately sensitive to detect hydatid antigen in serum and urine. Hence polyclonal antibodies to 24 kDa urinary hydatid antigen can be used as an alternative source of antibody to detect hydatid antigen in serum, urine and cyst fluid. In the present study, EITB was found to be highly specific test for detection of hydatid antibodiesin serum. 24 kDa protein was found to be specific and of diagnostic value in CE.

    Full Text Available Introduction : Infections caused by metacestode stage of the Echinococcus granulosus in humans result in disease named cystic echinococcosis. Aim: To present the outcomes of patients treated surgically for cystic echinococcosis of the liver. Material and methods : One hundred and nineteen patients treated in the period between 1989 and 2014 due to E. granulosus infection in the Department of General, Transplant, and Liver Surgery, Medical University of Warsaw were selected for this retrospective study. Diagnostic protocol included imaging examinations, i.e. ultrasonography and computed tomography of the abdomen. Blood samples where used to proceed sequential enzyme-linked immunosorbent assay (ELISA using Em2plus antigen as well as polymerase chain reaction (PCR to detect E. granulosus . Results : Surgery was the choice for treatment for almost all of the patients (98.3%. In 40 (34.2% patients right hemihepatectomy, in 19 (16.2% patients left hemihepatectomy, and in 21 (17.9% patients bisegementectomy were performed. Postoperative complications occurred in 4 (3.4% patients. In 3 patients biliary fistula requiring endoscopic treatment was observed, and 1 patient had subdiaphragmatic abscess successfully treated with drainage under ultrasound guidance. None of the patients died in the postoperative period, and the 1-, 5-, and 10-year survival rates were 100.0%, 90.9%, and 87.9%, respectively. Conclusions : Surgical treatment of the symptomatic cystic echinococcosis is the modality of choice for E. granulosus infection of the liver. Despite substantial development of diagnostic methods and new management opportunities, echinococcal infection still presents a challenge for epidemiologists, pharmacologists, and clinicists.

    Full Text Available Peracute infectious canine hepatitis (ICH was diagnosed in two young male dogs out of 56 dead canines presented for necropsy examination during the period of April 2009 to June 2010. These dogs were purebred, one- month old Alsatian and 5-month old Labrador. None of the dogs had received any vaccination or deworming treatment; both had died after illness lasting for six hours and twenty four hours respectively. The dogs had shown signs of depression, anorexia and fever. At necropsy, lymph nodes were swollen, edematous and congested; livers were enlarged, bright red and mottled with numerous small white foci. Petechial hemorrhages were seen in the mucosa. Excessive serosanguinous fluid was present in the abdominal cavities. Histologically, the most significant lesion was necrohemorrhagic hepatitis with single cell necrosis of hepatocytes, lacunose dilation of sinusoids filled with blood and numerous large, solid intranuclear inclusion bodies (IIBs in the hepatocytes and macrophages. Both eosinophilic and basophilic (amphophilic inclusions were seen. It has been observed that ICH is re-emerging in some endemic countries. Pet dogs should be regularly protected by effective vaccination.

  5. Liver scintigraphy of fulminant hepatitis

    Tamaki, Nagara; Ishihara, Takashi; Mori, Toru

    1980-01-01

    The liver scintigraphies of five patients with fulminant hepatitis were examined. Scintiphotos using sup(99m)Tc-phytate were taken within two weeks after the onset. Scintiphotos of 12 normal subjects, 11 cases with acute hepatitis, 17 cases with liver cirrhosis were served as control. Their scintiphotos showed reduction of the size, well-maintained uptake, mostly homogenous RI distribution, and no left lobe enlargement, which could differentiate them from the chronic liver dysfunction. In one of the cases chronological changes in liver scintigraphy were observed. The size of the liver was reduced progressively until the 16th day and re-enlarged at the 30th day and thereafter. Three indices [S/W, (R + L)/W, and L/R] were calculated. S: area of liver, R or L: longitudinal length of the right or left lobe, W: body width. Relative size of the liver expressed by S/W or (R + L)/W showed significant reduction in fulminant hepatitis compared with acute hepatitis. However, they were not different significantly from those of normal subjects. Except for liver cirrhosis, L/R (left lobe swelling index) did not show significant differences among fulminant hepatitis, normal subjects, and acute hepatitis. These indices were also useful in follow-up study of the liver scintigraphy. The liver scintigraphy in the early phase of fulminant hepatitis seems to reflect the degree of massive hepatic necrosis. It is also useful to differentiate chronic hepatic failure. Apparant reduction in scintigraphical liver size seems to suggest poor prognosis, however, it should also kept in mind that the size of the liver in this condition might change quite rapidly and greatly.

    Hepatic fibrosis (HF) is the pathological component of a variety of chronic liver diseases. Hepatic stellate cells (HSC) are the main collagen-producing cells in the liver and their activation promotes HF. If HSC activation and proliferation can be inhibited, HF occurrence and development can theoretically be reduced and even reversed. Over the past ten years, a number of studies have addressed this process, and here we present a review of HSC modulation and HF reversal. - Highlights: • We present a review of the modulation of hepatic stellate cells (HSC) and reversibility of hepatic fibrosis (HF). • HSC are the foci of HF occurrence and development, HF could be prevented and treated by modulating HSC. • If HSC activation and proliferation can be inhibited, HF could theoretically be inhibited and even reversed. • Prevention or reversal of HSC activation, or promotion of HSC apoptosis, immune elimination, and senescence may prevent, inhibit or reverse HF.

  11. Autoimmune hepatitis in children.

    Science.gov (United States)

    Mieli-Vergani, Giorgina; Vergani, Diego

    2002-08-01

    AIH, ASC, and de novo AIH after liver transplantation are childhood liver diseases of an autoimmune nature. The mode of presentation of AIH in childhood is variable, and the disease should be suspected and excluded in all children presenting with symptoms and signs of prolonged or severe acute liver disease. Although corticosteroids are effective in all types of childhood AIH, patients with LKM1 have a higher frequency of acute hepatic failure and relapse after corticosteroid withdrawal than do patients with ANA/SMA. ASC occurs commonly in the absence of inflammatory bowel disease, requires cholangiography for diagnosis, and improves during corticosteroid therapy. The development of AIH de novo in children who undergo liver transplantation for nonautoimmune liver disease may reflect interference with the maturation of T cells by immunosuppressive drugs.

    Full Text Available Viral hepatitis is a major public health problem in many countries all over the world and especially in Middle East, Asia, East-Europe, and Africa. The aim of our study was to assess the incidence of viral hepatitis A, B and C in Qatar and compare it with other countries. This is a retrospective cohort study, which was conducted at Hamad General Hospital, State of Qatar from 2002-2006. Patients who were screened and diagnosed with viral hepatitis were included in this study. The diagnostic classification of definite viral hepatitis was made in accordance with criteria based on the International Classification of Disease tenth revision (ICD-10. A total of 527 cases of hepatitis C, 396 cases of hepatitis B, 162 cases of hepatitis A and 108 cases of unspecified were reported during the year 2006. Reported incidence rate per 10,000 populations during the year 2006 for hepatitis A was 1.9, hepatitis B 4.7, and Hepatitis C 6.3. The proportion of hepatitis B and C was significantly higher in male population than females across the years (2002-2006. Hepatitis A was more prevalent in children below 15 years (72.3%, hepatitis B in adults aged above 15 years, and hepatitis C in the population above 35 years of age. The incidence of hepatitis A has been declining in Qataris and increasing in expatriates. There was a significant relationship in gender and age group of the patients with hepatitis A, B and C. We conclude that hepatitis has become a national health issue in Qatar. The incidence rate of hepatitis in Qatar is comparable to its neighboring countries, United Arab Emirates and Saudi Arabia. There is a need for further research on hepatitis and the associated risk factors.

    Viral hepatitis is a serious global public health problem. It is also a common cause of jaundice and gestational complications in pregnant women. Moreover, infected mothers can transmit the virus to their fetus or neonate, which may increase disease burden and decrease quality of life. To date, commercial vaccines have been developed for hepatitis A, B, and E and are available to the general population. The Advisory Committee on Immunization Practices currently accepts emergency vaccination against hepatitis A and B during pregnancy due to benefits that overweight the potential risks. While there are limited data from trials with limited numbers of samples that suggest the efficacy or safety of hepatitis B and E vaccines in pregnant women, additional data are necessary to provide evidence of vaccination during pregnancy.

    BACKGROUND: Patients with hepatic encephalopathy may present with extrapyramidal symptoms and changes in basal ganglia. These changes are similar to those seen in patients with Parkinson's disease. Dopamine agents (such as bromocriptine and levodopa, used for patients with Parkinson's disease) have...... therefore been assessed as a potential treatment for patients with hepatic encephalopathy. OBJECTIVES: To evaluate the beneficial and harmful effects of dopamine agents versus placebo or no intervention for patients with hepatic encephalopathy. SEARCH METHODS: Trials were identified through the Cochrane...... hepatic encephalopathy that were published during 1979 to 1982 were included. Three trials assessed levodopa, and two trials assessed bromocriptine. The mean daily dose was 4 grams for levodopa and 15 grams for bromocriptine. The median duration of treatment was 14 days (range seven to 56 days). None...

    Liver histology is characterized by T cell infiltrating the parenchyma as reported in acute hepatitis. Recently in HAA it has been demonstrated intrahepatic  and blood lymphocytes with  T cell repertoire similar to that of confirmed viral acute hepatitis. The expanded T cell clones return to a normal distribution after response to immunosuppressive treatment, suggesting the antigen or T cell clearance. Therapeutic options are the same as acquired aplastic anemia.

    Echinococcus multilocularis, Toxoplasma gondii and Toxocara spp. are foodborne parasites whose eggs or oocysts are spread in the environment via canid or felid faeces. They can cause infections in humans following the raw consumption of contaminated fruit or vegetables. In this study, their occurrence was investigated by quantitative polymerase chain reaction (qPCR) in 254 carnivore faeces deposited in 94 kitchen gardens of northeastern France that were sampled between two and six times from October 2011 to April 2013. Less than 25% of the sampled kitchen gardens contained more than 75% of the collected faeces. Of the 219 faeces that could be attributed to an emitter, cat accounted for 58%, fox for 32% and dog for 10%. Echinococcus multilocularis was detected in 35%, 11% and 7% of fox, dog and cat faeces, respectively, and Toxocara spp. in 33%, 12% and 5.5% of cat, fox and dog faeces, respectively. Toxoplasma gondii was detected in 2/125 cat faeces and 2/21 dog faeces. The 34 faeces that tested positive for E. multilocularis were found in only 19 out of the 94 sampled kitchen gardens, and the 40 faeces that tested positive for Toxocara spp. were found in 28 of them. Consequently, some kitchen gardens appeared particularly at risk of human exposure to foodborne parasites, including E. multilocularis responsible for alveolar echinococcosis (AE), which is a serious zoonosis. In endemic areas, kitchen garden owners should be informed about the zoonotic risk linked to carnivore faeces deposits and encouraged to set up preventive measures. © M.-L.

    Cystic echinococcosis (CE) is a highly endemic parasitic zoonosis in Iraq with substantial impacts on livestock productivity and human health. The objectives of this study were to study the abattoir-based occurrence of CE in marketed offal of sheep in Basrah province, Iraq, and to estimate, using a probabilistic modelling approach, the direct economic losses due to hydatid cysts. Based on detailed visual meat inspection, results from an active abattoir survey in this study revealed detection of hydatid cysts in 7.3% (95% CI: 5.4; 9.6) of 631 examined sheep carcasses. Post-mortem lesions of hydatid cyst were concurrently present in livers and lungs of more than half (54.3% (25/46)) of the positive sheep. Direct economic losses due to hydatid cysts in marketed offal were estimated using data from government reports, the one abattoir survey completed in this study, and expert opinions of local veterinarians and butchers. A Monte-Carlo simulation model was developed in a spreadsheet utilizing Latin Hypercube sampling to account for uncertainty in the input parameters. The model estimated that the average annual economic losses associated with hydatid cysts in the liver and lungs of sheep marketed for human consumption in Basrah to be US$72,470 (90% Confidence Interval (CI); ±11,302). The mean proportion of annual losses in meat products value (carcasses and offal) due to hydatid cysts in the liver and lungs of sheep marketed in Basrah province was estimated as 0.42% (90% CI; ±0.21). These estimates suggest that CE is responsible for considerable livestock-associated monetary losses in the south of Iraq. These findings can be used to inform different regional CE control program options in Iraq.

    Anorexia nervosa (AN) has the highest mortality rate of all psychiatric illnesses due to the widespread organ dysfunction caused by the underlying severe malnutrition. Starvation causes hepatocyte injury and death leading to a rise in aminotransferases. Malnutrition-induced hepatitis is common among individuals with AN especially as body mass index decreases. Acute liver failure associated with coagulopathy and encephalopathy can rarely occur. Liver enzymes may also less commonly increase as part of the refeeding process due to hepatic steatosis and can be distinguished from starvation hepatitis by the finding of a fatty liver on ultrasonography. Individuals with AN and starvation-induced hepatitis are at increased risk of hypoglycemia due to depleted glycogen stores and impaired gluconeogenesis. Gastroenterology and hepatology consultations are often requested when patients with AN and signs of hepatitis are hospitalized. It should be noted that additional laboratory testing, imaging, or liver biopsy all have low diagnostic yield, are costly, and potentially invasive, therefore, not generally recommended for diagnostic purposes. While the hepatitis of AN can reach severe levels, a supervised increase in caloric intake and a return to a healthy body weight often quickly lead to normalization of elevated aminotransferases caused by starvation.

    The ''Dimple sign'' has been coined by Baltaxe et al. in 1974 and was said to be useful angiographic sign of avascular tumor. Similar dimple can be seen in the margin of the liver on CT examination of the hepatic tumors. We called this hepatic dimple sign and its clinical usefulness on CT examination was studied with 133 cases of hepatic tumors. Among 133 cases, there were 68 cases of hepatocellular carcinoma, 57 cases of metastatic liver tumor, 5 cases of hemangioma of the liver and 3 cases of hepatoblastoma. Hepatic dimple sign was recognized on 2 cases of metastatic liver tumor, 1 case of hemangioma, and 1 case of carcinoma of the gallbladder with hepatic infiltration. Cases experienced in the affiliated hospitals were also studied. A case of hepatocellular carcinoma and a case of metastatic liver tumor were evaluated. These tumors were relativly large measuring over 5cm in the greatest diameter and low density areas were apparent on plain CT. Therefore, dimples in the hepatic margin seen in CT scan did not contribute to the diagnostic accuracy of the liver tumor in these cases. (author).

    Hepatic encephalopathy describes the array of neurological alterations that occur during acute liver failure or chronic liver injury. While key players in the pathogenesis of hepatic encephalopathy, such as increases in brain ammonia, alterations in neurosteroid levels, and neuroinflammation, have been identified, there is still a paucity in our knowledge of the precise pathogenic mechanism. This review gives a brief overview of our understanding of the pathogenesis of hepatic encephalopathy and then summarizes the significant recent advances made in clinical and basic research contributing to our understanding, diagnosis, and possible treatment of hepatic encephalopathy. A literature search using the PubMed database was conducted in May 2017 using “hepatic encephalopathy” as a keyword, and selected manuscripts were limited to those research articles published since May 2014. While the authors acknowledge that many significant advances have been made in the understanding of hepatic encephalopathy prior to May 2014, we have limited the scope of this review to the previous three years only.

    The Danish Committee on Adverse Drug Reactions received 1100 reports of suspected drug-induced hepatic injury during the decade 1978-1987. The causal relationship between drug and hepatic injury was classified as definite in 57 (5.2%) reports, probable in 989 (89.9%) reports, possible in 50 (4.......5%) reports and unclassifiable in four (0.4%) reports. Hepatic injuries accounted for 5.9% of all adverse drug reactions reported, and 14.7% of the lethal adverse drug reactions. A total of 47.2% were classified as acute cytotoxic, 16.2% as acute cholestatic and 26.9% as abnormal hepatic function. In 52 (4.......7%) cases the hepatic injury was lethal; only 14 (1.3%) cases were chronic. Halothane accounted for 25% of the cases. The incidence of halothane-induced hepatic injury is decreasing, and only one lethal case has been reported since 1981. Next to halothane, sulfasalazine was the drug most often suspected...

    Objective: To evaluate the angiographic feature of hepatic vein obstruction. Methods Forty-five patients (male 23, female 22, age 9-54 years) suffered from hepatic vein obstruction. The inferior vena cavography and the hepatic venography were performed in all cases. Results: IVC was free in 37 patients with hepatic vein obstruction, both IVC and HV were obstructed in 8 patients. The local or long stenosis of IVC was found in 31 inferior vena cavography. The diameter of IVC was normal in 12 patients. The sign of membranous dome was found in hepatic vein orifice in 5 cases and in accessory hepatic vein orifice in 4 cases. Intrahepatic venous collaterals were found in 45 cases. Conclusion: Hepatic vein obstruction can be reproached primarily in inferior vena cavography, the membranous dome is a direct sign of membranous obstruction of HV and AHV in inferior vena cavography. The selected hepatic venography can provide reliable evidence to diagnose hepatic vein obstruction

    The most highly developed radioimmunoassay test system in medical virology is proving of exceptional value in research aimed at controlling and eventually eradicating the scourge of human hepatitis. The use of radioimmunoassay in detecting hepatitis A (HAV) and hepatitis B (HBV) viruses is discussed. The hepatitis A virus is an enterovirus which infects the gastrointestinal tract and is usually transmitted by contaminated food, milk or water. Hepatitis B spreads mainly by the parenteral rate. Bedbugs and ticks are considered as possible transmitters of HBV. Another important contribution of radioimmunoassay is the ability to monitor the immune response of persons at risk who are vaccinated against hepatitis B

    Twenty-nine patients with hepatic artery occlusion were treated with additional hepatic infusion or embolization through extrahepatic collaterals. Seventeen courses of hepatic infusion were performed in 13 patients through the inferior pancreaticoduodenal artery, left gastric artery, or right gastric artery. Twenty-five hepatic embolization procedures were performed in 16 patients through the right and left phrenic arteries, left and right gastric arteries, pancreaticoduodenal artery, gastroduodenal artery, or omentoepiploic artery. In one patient gastric ulcers developed following left gastric artery infusion. No complication related to the embolization procedure was observed in the embolization group. The extrahepatic collaterals are important alternative routes for continuous transcatheter management of hepatic neoplasms following hepatic artery occlusion.

    Lemon, Stanley M; Walker, Christopher M

    2018-05-07

    Over the past two decades, progress in understanding human infections with hepatitis A virus (HAV) and hepatitis E virus (HEV) has been eclipsed by the priority of combating persistent hepatitis B virus (HBV) and hepatitis C virus (HCV) infections. During that time, the global burden of liver disease caused by enteric hepatitis viruses has not abated. Because of vaccines, hepatitis A has become increasingly a disease of adults instead of early childhood in many regions of the world, resulting in an age-related shift toward more severe disease. HEV has remained endemic in many developing countries, and in well-developed, economically advanced countries it is now recognized as a cause of chronic, progressive liver disease in individuals with compromised immunity. The goal of this collection of articles is to review recent progress and to shine a bright light on gaps in our understanding of how these viruses replicate, cause disease, interact with the liver and host immune system, and are transmitted, along with prospects for improved control in human populations. Renewed efforts to study and compare HAV and HEV biology in humans and animal models have high potential to enhance our understanding of host-pathogen balance in the liver, and may contribute ultimately to the control of other infectious diseases of the liver.

    Objective: To assess and compare the severity of depression in chronic hepatitis B (CHB), chronic hepatitis C (CHC) and healthy subjects. Study Design: Comparative study. Place and Duration of Study: Shifa International Hospital, Islamabad from July 2011 to February 2012. Methodology:A total of 206 subjects were divided in three groups. Group-I (chronic hepatitis C, n = 95), group-II (chronic hepatitis B, n = 29) and group-III (healthy subjects, n = 82). They were matched for age, gender and socioeconomic status and were compared for frequency and severity of depression as measured by Hospital Anxiety and Depression Scale (HADS). Results: Some degree of depression was noted in all groups. Frequency of depression was 72.6% in group-I, 58.6% in group-II and 37.8% in group-III (p value < 0.001). Conclusion: Both CHC and CHB had high frequency of some degree of depression. Hepatitis C patients had more depressive features than CHB. It is worthwhile to do more close mental health observation in them. A multidisciplinary team including a psychiatric specialist can help in this approach. (author)

    A region of interest angiohepatogram was obtained with intravenous injection of 10mCi of sup(99m)Tc-Sn-colloid and a data processing system. Furthermore, the ratio of hepatic arterial blood flow volume to total hepatic blood flow volume was calculated according to Ueda's method, and the correlation of this calculated ratio and the degree of extrahepatic distribution of sup(99m)Tc-Sn-colloid (spleen to liver, and bone marrow to liver activity ratio) was examined. Most cases of liver cirrhosis and Banti's syndrome showed the increased hepatic arterial blood flow ratio (liver cirrhosis: 43.5+-9.5%, Banti's syndrome 48.8+-4.9%) in contrast with 18.1+-4.6% in normal cases, and its ratio showed much higher values in the presence of portal hypertension manifestations (esophageal varix and ascites). The hepatic arterial blood flow ratio showed increased values in the case of markedly increased extrahepatic activity, e.g. liver cirrhosis, and the correlation of the ratio and extrahepatic activity degree of sup(99m)Tc-Sn-colloid was significant statistically. From these results, a region of interest angiohepatogram was supposed to be useful for the prediction of the hemodynamic change, as well as, the improvement of diagnostic accuracy with radioisotope in diffuse hepatic disease, especially liver cirrhosis. Moreover, the hemodynamic change of liver, especially the reduction of the effective hepatic blood flow volume via the portal vein was considered to be closely concerned in the mechanism of increased extrahepatic activity of RI colloid in diffuse hepatic disease.

    Organ and region-selective intra-arterial chemotherapy have been used for more than two decades to treat malignant neoplasms in the extremities, head and neck region, pelvis, liver, and other areas. Substantial evidence of improved response to regional chemotherapy now exists, but there are stringent requirements for successful application of the regional technique. First, the chemotherapeutic agent employed must have appropriate pharmacokinetic and pharmacodynamic properties. Second, the drug must be reliably delivered to the tumor-bearing area. This typically requires an arteriographic assessment of the vascular supply of the tumor, followed by placement of a therapeutic catheter and confirmation that the ''watershed'' perfusion distribution from the catheter truly encompasses the tumor. Optimal catheter placement also minimizes perfusion of nontarget organs. Radionuclide perfusion imaging with technetium 99m-labeled particles, either microspheres or macroaggregates of albumin, has become the method of choice for making these assessments. Catheter placement itself is considered by many to represent a type of ''therapeutic'' intervention. However, once the catheter is in the hepatic artery the radionuclide perfusion technique can be used to assess adjunctive pharmacologic maneuvers designed to further exploit the regional approach to chemotherapy. This chapter presents the technetium Tc 99m macroaggregated albumin method for assessing catheter placement and the pharmacokinetic rationale for regional chemotherapy, and discusses two promising avenues for further intervention

    After the discovery of HCV in 1989 a great amount of data has been produced in order to identify a possible aetiology for a number of idiopathic diseases, especially those with a suspected immune origin. Many associations have not been confirmed by prospective studies (as in the case of autoimmune hepatitis); other immune abnormalities, such as the emergence of non organ-specific autoantibodies and cryoglobulins, have been reported by many specific studies. To date, the link between HCV and autoreactivity is tentatively explained on the basis of sequence homologies shared by the HCV polyprotein and "self" proteins (such as CYP 2D6, target of anti-LKM1) (molecular mimicry mechanism); a second interpretation relies on the demonstration that the HCV - B lymphocyte interaction is able to induce a polyclonal B cell activation, an important cofactor for the development of clinically relevant B-lymphocyte autoimmune disorders. In this review we will focus on the major aspects of the autoimmune phenomena in HCV-infected patients, their clinical and therapeutical implications.

    Infection with hepatitis viruses can lead to acute hepatitis with the risk of developing liver failure. Chronic viral hepatitis may evolve into liver cirrhosis and hepatocellular carcinoma. Thus, prevention of viral hepatitis and its sequels is essential. Vaccination against hepatitis A is successful in almost all individuals. Protective antibodies maintain for at least 20 years. Booster vaccinations are not necessary. Since the introduction of hepatitis A vaccines, the incidence of new HAV-infections has declined significantly. Hepatitis B vaccines are safe and highly effective. Special populations such as dialysis patients or immunocompromised patients require special vaccine schedules. New vaccines with improved adjuvants are currently being tested in clinical trials. So far there is no hepatitis C vaccine on the horizon. Prophylaxis of HCV-infections relies primarily on hygiene measures. Early therapy of acute hepatitis C can prevent chronic hepatitis C. HDV-infection can only be established if HBsAg is present. Thus, prevention of hepatitis B or elimination of HBsAg means prevention of hepatitis delta. Hepatitis E vaccines have been evaluated in phase III studies. The development of HEV vaccines becomes more relevant since chronic HEV infections have been reported in immunosuppressed individuals.

    Parvovirus B19 infection can present with myriads of clinical diseases and syndromes; liver manifestations and hepatitis are examples of them. Parvovirus B19 hepatitis associated aplastic anemia and its coinfection with other hepatotropic viruses are relatively underrecognized, and there is sufficient evidence in the literature suggesting that B19 infections can cause a spectrum of liver diseases from elevation of transaminases to acute hepatitis to fulminant liver failure and even chronic hepatitis. It can also cause fatal macrophage activation syndrome and fibrosing cholestatic hepatitis. Parvovirus B19 is an erythrovirus that can only be replicate in pronormoblasts and hepatocytes, and other cells which have globosides and glycosphingolipids in their membrane can also be affected by direct virus injury due to nonstructural protein 1 persistence and indirectly by immune mediated injury. The virus infection is suspected in bone marrow aspiration in cases with sudden drop of hemoglobin and onset of transient aplastic anemia in immunosuppressed or immunocompetent patients and is confirmed either by IgM and IgG positive serology, PCR analysis, and in situ hybridization in biopsy specimens or by application of both. There is no specific treatment for parvovirus B19 related liver diseases, but triple therapy regimen may be effective consisting of immunoglobulin, dehydrohydrocortisone, and cyclosporine.

    Haga, Yuki; Kanda, Tatsuo; Sasaki, Reina; Nakamura, Masato; Nakamoto, Shingo; Yokosuka, Osamu

    2015-12-14

    Nonalcoholic fatty liver disease (NAFLD) including nonalcoholic steatohepatitis (NASH) is globally increasing and has become a world-wide health problem. Chronic infection with hepatitis B virus or hepatitis C virus (HCV) is associated with hepatic steatosis. Viral hepatitis-associated hepatic steatosis is often caused by metabolic syndrome including obesity, type 2 diabetes mellitus and/or dyslipidemia. It has been reported that HCV genotype 3 exerts direct metabolic effects that lead to hepatic steatosis. In this review, the differences between NAFLD/NASH and viral hepatitis-associated steatosis are discussed.

    Hepatic steatosis is one of the most common liver disorders in the general population. The main cause of hepatic steatosis is nonalcoholic fatty liver disease (NAFLD), representing the hepatic component of the metabolic syndrome, which is characterized by type 2 diabetes, obesity, and dyslipidemia. Insulin resistance and excess adiposity are considered to play key roles in the pathogenesis of NAFLD. Although the risk factors for NAFLD are well established, the genetic basis of hepatic steatos...

    Full Text Available Estima-se que cerca de 3% da população mundial esteja infectada pelo vírus da hepatite C. Todos os que receberam transfusão de sangue ou seus componentes e os usuários de drogas podem estar infectados. Procedimentos odontológicos, médicos, tatuagem ou acupuntura também constituem fatores de risco. A infecção se cronifica em até 85% dos indivíduos, com evolução assintomática durante anos ou décadas e apresentação clínica variada. Para o diagnóstico, a determinação do anti-VHC revela-se muito sensível e a confirmação se faz pela determinação do RNA-VHC no sangue; o estadiamento da doença e a avaliação da atividade inflamatória pela biópsia hepática. O tratamento objetiva deter a progressão da doença hepática através da inibição da replicação viral. Devido à baixa eficácia terapêutica aliada a importantes efeitos colaterais do interferon e da ribavirina, esses medicamentos encontram indicações e contra-indicações específicas. Vários fatores preditivos de resposta ao tratamento, principalmente a carga viral e o genótipo do VHC, mostram-se úteis na avaliação dos pacientes.It has been estimated that 3% of the world population is infected with the hepatitis C virus. Those who are blood product recipients or have been illicit drug users are at risk. Dental and medical procedures as well as tattooing and acupuncture are also risk factors. Chronic infection occurs in up to 85% of infected cases but they may remain without symptoms during years or even decades, and clinical presentation varies. Determination of anti-HCV in sera is a fairly sensitive tool for the diagnosis, and confirmation requires the identification of HCV-RNA. Staging of the liver disease as well as definition of its present activity can be graded by liver biopsy. The aim of treatment is to stop the progression of the hepatic disease by inhibiting viral replication. Due to the low therapeutic efficacy combined with important side

  14. Biliary Stricture Following Hepatic Resection

    Directory of Open Access Journals (Sweden)

    Jeffrey B. Matthews

    1991-01-01

    Full Text Available Anatomic distortion and displacement of hilar structures due to liver lobe atrophy and hypertrophy occasionally complicates the surgical approach for biliary stricture repair. Benign biliary stricture following hepatic resection deserves special consideration in this regard because the inevitable hypertrophy of the residual liver causes marked rotation and displacement of the hepatic hilum that if not anticipated may render exposure for repair difficult and dangerous. Three patients with biliary stricture after hepatectomy illustrate the influence of hepatic regeneration on attempts at subsequent stricture repair. Following left hepatectomy, hypertrophy of the right and caudate lobes causes an anteromedial rotation and displacement of the portal structures. After right hepatectomy, the rotation is posterolateral, and a thoracoabdominal approach may be necessary for adequate exposure. Radiographs obtained in the standard anteroposterior projection may be deceptive, and lateral views are recommended to aid in operative planning.

  15. Viral hepatitis in the elderly.

    Science.gov (United States)

    Carrion, Andres F; Martin, Paul

    2012-05-01

    As life expectancy continues to rise, elderly adults represent a rapidly growing proportion of the population. The likelihood of complications of acute and chronic liver disease and overall mortality are higher in elderly populations. Several physiological changes associated with aging, greater prevalence of co-morbid conditions, and cumulative exposure to hepatotropic viruses and environmental hepatotoxins may contribute to worse outcomes of viral hepatitis in the elderly. Although pharmacotherapy for hepatitis B and C continues to evolve, the efficacy, tolerability, and side effects of these agents have not been studied extensively in elderly adults. Immunization against hepatitis A and B in naïve elderly adults is an important public health intervention that needs to be revised and broadened.

    DEFF Research Database (Denmark)

    Risør, Louise M; Fenger, Mogens; Olsen, Niels Vidiendal

    2016-01-01

    The main function of erythropoietin (EPO) is to maintain red blood cell mass, but in recent years, increasing evidence has suggested a wider biological role not solely related to erythropoiesis, e.g. angiogenesis and tissue protection. EPO is produced in the liver during fetal life, but the main...... production shifts to the kidney after birth. The liver maintains a production capacity of up to 10% of the total EPO synthesis in healthy controls, but can be up-regulated to 90-100%. However, the hepatic EPO synthesis has been shown not to be adequate for correction of anemia in the absence of renal......, which lead to arterial hypotension, hepatic nephropathy and anemia. An increase in EPO due to renal hypoperfusion, hypoxia and anemia or an EPO-mediated hepato-protective and regenerative mechanism is plausible. However, poor hepatic synthesis capacity, a decreasing co-factor level and inflammatory...

    Full Text Available Introduction: The association of acute viral hepatitis and acute pancreatitis is well described. This study was conducted to find out the frequency of pancreatic involvement in acute viral hepatitis in the Nepalese population. Methods: Consecutive patients of acute viral hepatitis presenting with severe abdominal pain between January 2005 and April 2010 were studied. Patients with history of significant alcohol consumption and gall stones were excluded. Acute viral hepatitis was diagnosed by clinical examination, liver function test, ultrasound examination and confirmed by viral serology. Pancreatitis was diagnosed by clinical presentation, biochemistry, ultrasound examination and CT scan. Results: Severe abdominal pain was present in 38 of 382 serologically-confirmed acute viral hepatitis patients. Twenty five patients were diagnosed to have acute pancreatitis. The pancreatitis was mild in 14 and severe in 11 patients. The etiology of pancreatitis was hepatitis E virus in 18 and hepatitis A virus in 7 patients. Two patients died of complications secondary to shock. The remaining patients recovered from both pancreatitis and hepatitis on conservative treatment. Conclusions: Acute pancreatitis occurred in 6.5 % of patients with acute viral hepatitis. Cholelithiasis and gastric ulcers are the other causes of severe abdominal pain. The majority of the patients recover with conservative management. Keywords: acute viral hepatitis, acute pancreatitis, pain abdomen, hepatitis E, hepatitis A, endemic zone

    A region of interest angiohepatogram was obtained with intravenous injection of 10mCi of sup(99m)Tc-Sn-colloid and a data processing system. Furthermore, the ratio of hepatic arterial blood flow volume to total hepatic blood flow volume was calculated according to Ueda's method, and the correlation of this calculated ratio and the degree of extrahepatic distribution of sup(99m)Tc-Sn-colloid (spleen to liver, and bone marrow to liver activity ratio) was examined. Most cases of liver cirrhosis and Banti's syndrome showed the increased hepatic arterial blood flow ratio (liver cirrhosis: 43.5+-9.5%, Banti's syndrome 48.8+-4.9%) in contrast with 18.1+-4.6% in normal cases, and its ratio showed much higher values in the presence of portal hypertension manifestations (esophageal varix and ascites). The hepatic arterial blood flow ratio showed increased values in the case of markedly increased extrahepatic activity, e.g. liver cirrhosis, and the correlation of the ratio and extrahepatic activity degree of sup(99m)Tc-Sn-colloid was significant statistically. From these results, a region of interest angiohepatogram was supposed to be useful for the prediction of the hemodynamic change, as well as, the improvement of diagnostic accuracy with radioisotope in diffuse hepatic disease, especially liver cirrhosis. Moreover, the hemodynamic change of liver, especially the reduction of the effectivehepatic blood flow volume via the portal vein was considered to be closely concerned in the mechanism of increased extrahepatic activity of RI colloid in diffuse hepatic disease.

    2015-06-28

    Although only a single serotype of hepatitis E virus (HEV), the causative agent of hepatitis E, has been identified, there is great genetic variation among the different HEV isolates reported. There are at least four major recognized genotypes of HEV: genotypes 1 and 2 are mainly restricted to humans and linked to epidemic outbreaks in nonindustrialized countries, whereas genotypes 3 and 4 are zoonotic in both developing and industrialized countries. Besides human strains, genotype 3 and 4 strains of HEV have been genetically characterized from swine, sika deer, mongooses, sheep, and rabbits. Currently, there are approximately 11,000 human and animal sequences of HEV available at the International Nucleotide Sequence Database Collaboration. HEV is the major cause of waterborne outbreaks of hepatitis in areas of poor sanitation. Additionally, it is responsible for sporadic cases of viral hepatitis in not only endemic but industrialized countries as well. Transmission of HEV occurs predominantly by the fecal-oral route, although parenteral and perinatal routes have been reported. HEV infection develops in most individuals as a self-limiting, acute, icteric hepatitis; with mortality rates around 1%. However, some affected individuals will develop fulminant hepatic failure, a serious condition that is frequently fatal without a liver transplant. This complication is particularly common when the infection occurs in pregnant women, where mortality rates rise dramatically to up to 25%. Among the preventive measures available to avoid HEV infection, two separate subunit vaccines containing recombinant truncated capsid proteins of HEV have been shown to be highly effective in the prevention of disease. One of them, HEV 239, was approved in China, and its commercialization by Innovax began in November 2012 under the name Hecolin(®).

  7. Adipokines and Hepatic Insulin Resistance

    Science.gov (United States)

    Hassan, Waseem

    2013-01-01

    Obesity is a major risk factor for insulin resistance and type 2 diabetes. Adipose tissue is now considered to be an active endocrine organ that secretes various adipokines such as adiponectin, leptin, resistin, tumour necrosis factor-α, and interleukin-6. Recent studies have shown that these factors might provide a molecular link between increased adiposity and impaired insulin sensitivity. Since hepatic insulin resistance plays the key role in the whole body insulin resistance, clarification of the regulatory processes about hepatic insulin resistance by adipokines in rodents and human would seem essential in order to understand the mechanism of type 2 diabetes and for developing novel therapeutic strategies to treat it.

    2006-06-01

    We evaluated the clinical and virological characteristics of hepatitis A virus infection in persons concomitantly infected with hepatitis B virus (HBV) or hepatitis C virus (HCV). We enrolled 21 patients with acute hepatitis A and chronic hepatitis with no sign of liver cirrhosis, 13 patients who were positive for hepatitis B surface antigen (case B group), 8 patients who were anti-HCV positive (case C group), and 21 patients with acute hepatitis A without a preexisting liver disease (control A group). Two control groups of patients with chronic hepatitis B (control B group) or C (control C group) were also chosen. All control groups were pair-matched by age and sex with the corresponding case group. Fulminant hepatitis A was never observed, and hepatitis A had a severe course in 1 patient in the case B group and in 1 patient in the control A group. Both patients recovered. On admission, HBV DNA was detected in 1 patient in the case B group (7.7%) and in 13 patients (50%) in the control B group; HCV RNA was found in no patient in the case C group and in 16 patients (81.2%) in the control C group. Of 9 patients in the case B group who were followed up for 6 months, 3 became negative for hepatitis B surface antigen and positive for hepatitis B surface antibody, 2 remained positive for hepatitis B surface antigen and negative for HBV DNA, and 4 became positive for HBV DNA with a low viral load [corrected] Of 6 patients in the case C group who were followed up for 6 months, 3 remained negative for HCV RNA, and 3 had persistently low viral loads. Concomitant hepatitis A was always self-limited, associated with a marked inhibition of HBV and HCV genomes, and possibly had a good prognosis for the underlying chronic hepatitis.

    Hepatitis B and C are two potentially life threatening liver infections. Lebanon is ranked as a zone of moderate endemicity. This study aimed to determine the prevalence of hepatitis B and C in Lebanon and their distribution according to age, region and sex. This national prospective cross-sectional study was conducted from January 2011 till December 2012 in the six Lebanese Governorates in collaboration with municipalities, the Ministry of Public Health, Health Centres and dispensaries. An upcoming screening for hepatitis B and C was announced? in different districts of each Governorate. All individuals presenting to local laboratory, not known to have chronic hepatitis, were asked for a blood sample and answered a questionnaire addressing sex, age, place of birth and residence. Screening tests were "Abbots" for hepatitis B and "Human Hexagon" for hepatitis C. PCR testing was used to confirm the positivity of the previous tests. Of 31147 individuals screened, 542 had a rapid test positive for HBV (prevalence 1.74%, 95% CI 1.6-1.89) with a male to female ratio of 1.08. This prevalence was higher in the South and Nabatieh (1.9%) compared to Beirut (0.73%). Of 31,147 individuals screened, 64 had a rapid test positive for HCV (prevalence 0.21%, 95% CI 0.16-0.27) with a male to female ratio of 0.85. This prevalence was higher in Nabatieh (0.61%) compared to Mount Lebanon (0.08%). The prevalence of HBV and HCV in Lebanon is 1.74% and 0.21%, respectively with a higher prevalence in South and Nabatieh districts. These data rank Lebanon amongst countries with low endemicity for both viruses. Decrease in the prevalence of HBV is due to awareness campaign as well as success of the MOPH National Hepatitis Program in vaccinating all new born since 1998 and in screening and vaccinating high risk groups.

    2005-01-01

    Objective: To investigate the value of CT perfusion in the early diagnosis of hepatic diffuse disease. Methods: Fourteen male Wistar rats of control group and 14 of test group at stages of hepatitis, hepatic fibrosis, hepatic cirrhosis which were induced with diethylnitrosamine (DEN), were studied with CT perfusion respectively. CT perfusion data of different stages were compared and pathologic analysis were performed. Results: Density-time curves of CT perfusion were satisfactory and all perfusion data could be obtained. During the period of hepatitis developing into early stage of hepatic cirrhosis, hepatic artery flow (HAF) trended to increase in test group, mean transmit time (MTT) prolonged obviously, blood flow (BF) and volume (BV) declined. While in control group, HAF declined slightly, MTT, BV and BF increased. Statistic analysis showed the differences of HAF and MTT at different stages between control and test groups were significant (P<0.05 ); the differences of BV and BF between hepatitis and hepatic cirrhosis, hepatic fibrosis and early stage of hepatic cirrhosis in test group were significant (P<0.05), but no significant difference between hepatitis and hepatic fibrosis. The corresponding pathologic changes at stage of hepatitis was swelling of hepatic cells; sinusoids cap illarization and deposition of collagen in the extravascular Disse's spaces were the main changes relating to hepatic blood perfusion at stage of fibrosis and early stage of cirrhosis. Conclusion: The method of CT scan can reflect some changes of hepatic blood perfusion in rats with hepatitis, hepatic fibrosis and early stage of cirrhosis. The data of CT perfusion, especially the changes should be valuable for clinical early diagnosis, treatment and follow-up. (authors)

Nowadays there are three different etiologic big groups for HE: type A associated with acute liver failure; type B associated with portosystemic bypass; and type C associated with cirrhosis of the liver. The staging of HE is still based on classic West Haven system, but a latent Grade 0 was introduced (the so called minimal HE; remaining the aggra- vating HE from Grade 1 (subtle changes at clinical examination to Grade 4 (coma. In this work a bibliographic review was made on 30 of the most pertinent and recent papers, focusing in psychopathology, physiopathology, etiology and staging of this clinical entity transversal to Psychiatry and Gastroenterology. Alterations are described in vigility and conscience like temporal, spatial and personal disorientation. Attention, concentration and memory are impaired very early, on latent phase and can be accessed through neuropsychological tests. Mood oscillates between euphoric and depressive. Personality changes begin obviously and abruptly or in a subtle and insidious way. There can be changes in perception like visual hallucinations or even of acoustic-verbal. The thought disorders can be of delusional type, paranoid, systematized or not, but also monothematic ala Capgras Syndrome. Speech can be accelerated, slowed down or completely in

    There are discrepant data on whether men or women have a higher risk for hepatic steatosis. To examine the influence of gender on hepatic adiposity in teenagers and young adults. We measured subcutaneous abdominal fat (SAF), intra-abdominal fat (IAF) and hepatic tissue density (a surrogate measure of hepatic fat) using CT in 505 healthy teenagers and young adults (254 males, 251 females; ages 15-22.9 years). Overall, compared to men, women had higher values of SAF (P 0.05). When compared to overweight and obese young women, overweight and obese young men are at greater risk for hepatic steatosis, independent of IAF. (orig.)

    Objective: To assess CT manifestations and diagnostic value in patients with hepatic tuberculosis. Methods: Ten cases of hepatic tuberculosis proved by hepatic biopsy or surgical specimens were analyzed retrospectively. Results: This group of hepatic tuberculosis included three types. (1) Five cases of miliary hepatic tuberculosis demonstrated that the liver swelled diffusely associated with multiple miliary low attenuations, and showed no enhancement after contrast agents administration. (2) Three cases of tubercle hepatic tuberculosis depicted multiple hypodensity areas or mixed density regions in the liver. The extension of lesions reduced in arterial phase, and a ring-like enhancement was displayed in the portal phase. (3) One case of hepatic tuberculoma illustrated solitary space occupying lesion accompanied with central necrosis. The envelope was thin and smooth which enhanced slightly after injecting Gd-DTPA. Another one was hepatic abscess and depicted fluid-fluid level inside the lesion. Conclusions: The CT manifestations of miliary hepatic tuberculosis lack of characteristics, it is hard to make the diagnosis clear-cut unless integrating the medical history and lab test. The 'powder calcification' findings of tubercle hepatic tuberculosis is propitious to draw a qualitative diagnosis. And the feature of hepatic tuberculomas with fluid- fluid level is in favor of making a differential diagnosis against parallel tumors. (authors)

    Hepatitis has gone along with human history since its origins, due to its prompt identifiability linked to jaundice as a symptom. Written evidence of outbreaks of epidemic jaundice can be tracked back a few millenniums before Christ. Unavoidable confusion arises due to the overlap of different sources possibly linked to different aetiologies, identified over time as epidemic jaundice (HAV or HEV hepatitis?) and serum hepatitis (HBV or HCV hepatitis?). The journey that brought to recognize viruses as the main cause of jaundice was long and started midway during the last century, when the infectious hypothesis, which had taken place step by step, was finally confirmed by epidemiological investigations of an outbreak occurring in the US army in 1942, after a yellow fever immunization campaign. Further research identified two clinically different types of hepatitis, called for the first time hepatitis A and hepatitis B.

    To review the nonoperative and operative management of blunt hepatic injury in the adult trauma population. Although liver injury scale does not predict need for surgical intervention, a high-grade complex liver injury should alert the physician to a patient at increased risk of hepatic complications following nonoperative management. Blunt hepatic injury remains a frequent intraabdominal injury in the adult trauma population. The management of blunt hepatic injury has undergone a major paradigm shift from mandatory operative exploration to nonoperative management. Hemodynamic instability with a positive focused abdominal sonography for trauma and peritonitis are indications for emergent operative intervention. Although surgical intervention for blunt hepatic trauma is not as common as in years past, it is imperative that the current trauma surgeon be familiar with the surgical skill set to manage complex hepatic injuries. This study represents a review of both nonoperative and operative management of blunt hepatic injury.

    Liver scintigraphy was performed in 12 cases with fulminant hepatitis, in 8 cases with severe acute hepatitis and in 44 cases with acute hepatitis. Scintiphotoes of severe hepatitis showed reduction of liver size, marked visualization of the bone marrow and the spleen, so this pattern was useful to differentiate from acute hepatitis. Relative size of the liver calculated by A.L.I. (anterior liver index) showed significant reduction in severe hepatitis compared with that of acute hepatitis. Three of five patients with died of severe hepatitis showed high uptake in the lung and ribs, but none of fifteen patients with severe hepatitis who recovered showed the abnormal accumulation in the lung and in the ribs.

    The impact of chronic hepatitis B on the clinical outcome of acute hepatitis A remains controversial. The aim of present study was to evaluate the clinical characteristics of acute hepatitis A in cases with underlying chronic hepatitis B compared to cases of acute hepatitis A alone. Data on 758 patients with acute hepatitis A admitted at two university-affiliated hospitals were reviewed. Patients were classified into three groups: group A, patients with both acute hepatitis A and underlying chronic hepatitis B (n = 27); group B, patients infected by acute hepatitis A alone whose sexes and ages were matched with patients in group A (n  = 54); and group C, patients with acute hepatitis A alone (n = 731). None of the demographic features of group A were significantly different from those of group B or C, except for the proportion of males and body weight, which differed from group C. When comparing to group B, clinical symptoms were more frequent, and higher total bilirubin and lower albumin levels were observed in group A. When comparing to group C, the albumin levels were lower in group A. There were no differences in the duration of hospital stay, occurrence of acute kidney injury, acute liver failure, prolonged cholestasis, or relapsing hepatitis. This study revealed that clinical symptoms and laboratory findings were less favorable for patients with acute hepatitis A and chronic hepatitis B compared to those with acute hepatitis A alone. However, there were no differences in fatal outcomes or serious complications. Copyright © 2012 Wiley Periodicals, Inc.

    To evaluate the usefulness of screening liver ultrasonography (US) for hepatocellular carcinoma (HCC) detection in patients with chronic hepatitis or hepatic cirrhosis caused by hepatitis B virus (HBV). A retrospective study was performed with 1,189 patients with clinical hepatopathy caused by HBV who underwent screening liver US for HCC detection at least twice. All patients were followed up with liver US examinations (mean, 8.3 times), CT, or MR for at least 3 months (range, 3-102 months; mean, 47 months) for the detection of HCC. The study population was divided into two groups: chronic hepatitis (n=492) and hepatic cirrhosis (n=697), which was further divided into two groups with (n=156) or without (n=541) evident shrinkage. The radiologic examinations that had detected HCC for the first time were analyzed and compared between the groups. Among 20 (4.1%) patients with chronic hepatitis and 132 (18.9%) patients with hepatic cirrhosis diagnosed as HCC, screening US was the modality of detection in 17 (85.0%) of 20 patients with chronic hepatitis and 76 (57.6%) of 132 patients with hepatic cirrhosis (p=0.038, Chi-square test). The detection rate of HCC on screening US between the chronic hepatitis and hepatic cirrhosis with evident shrinkage (51.4%, 19/37) showed a significant difference (p=0.027, Chi-square test). For chronic liver disease caused by HBV, screening US for HCC detection is more useful in patients with chronic hepatitis than with hepatic cirrhosis with evident shrinkage

    Tracer quantities of colloidal 198 Au were used to estimate the hepatic blood flow in normal children and in children with active or progressive chronic hepatitis and also to obtain scintigrams of the liver. In active chronic hepatitis a significant decrease in HBF values was observed, suggesting that the method may be used as a diagnostic criterion which is superior to hepatic scintigraphy. In progressive chronic hepatitis HBF values even lower than those in active hepatitis were observed. Together with more characteristic clinical findings and abnormal results of biochemical function tests, they underline the value of the method in estimating the severity and the evolution of the disease.

    Acquired aplastic anemia(aAA is a severe and rare disease, characterized by hematopoietic bone marrow failure and peripheral cytopenia. The pathophysiology is immune mediated in most cases, activated T1 lymphocytes have been identified as effector cells . The disease can be successfully treated with combined immunosuppressive therapy or allogeneic hematopoietic stem cell transplantation.

    Hepatitis-associated aplastic anemia (HAA  is a syndrome of bone marrow failure following the development of acute seronegative hepatitis. HAA syndrome most often affects young males who presented severe pancytopenia two to three months after an episode of acute hepatitis. The clinical course of hepatitis is more frequently benign but a fulminant severe course is also described. The bone marrow failure can be explosive and severe and it is usually fatal if untreated, no correlations have been observed between severity of hepatitis and AA.

    In none of the  studies a specific virus could be identified and most cases are seronegative for known hepatitis viruses. The clinical characteristics  and response to immunotherapy indicate a central role for immune-mediated mechanism in the pathogenesis of HAA. The initial

    Hepatitis B virus (HBV) and hepatitis C virus (HCV), discovered as causative viruses of post-transfusion hepatitis, become persistent infections, leading to chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). For HCV, recent IFN-free direct-acting antiviral (DAA) therapies have increased sustained virological response (SVR) rates and reduced adverse events. IFN-based therapies, still the standard of care in Asian countries, are influenced by IL28B genetic variants and the liver fibrosis stage, but the DAA combinations obscure the influence of these factors. These new therapies can eradicate HCV and prevent HCC development. On the other hand, it is difficult to eradicate HBV completely. Although HBV infection can be prevented by vaccination, reactivation of HBV following anti-cancer chemotherapy and immunosuppressive therapy is a well-known complication. HBV reactivation has been reported to be associated with anti-CD20 monoclonal antibody rituximab-containing chemotherapy and TNF-α inhibitor-containing immunosuppressive therapy in HBV-resolved patients. Our prospective observational study revealed that monthly monitoring of HBV DNA was useful for preventing HBV reactivation-related hepatitis among B-cell non-Hodgkin lymphoma patients with resolved HBV infection following rituximab-steroid-chemo, suggesting that preemptive therapy guided by serial HBV DNA monitoring should be recommended. Recently, highly sensitive HBsAg detection by Lumipulse HBsAg-HQ may be useful for several clinical applications. The sensitivity of this assay (5 mIU/mL) was approximately 10-fold higher than Abbott ARCHITECT, but still lower than HBV-DNA assays. The convenient HBsAg-HQ may be useful for detecting occult HBV infection and HBV reactivation in relatively low-risk groups except for those receiving rituximab-steroid-chemo. [

It can be defined as a neuropsychiatric syndrome caused by portosystemic venous shunting, ranging from minimal to overt hepatic encephalopathy or coma. Its pathophysiology is still unclear, although increased levels of ammonia play a key role. Diagnosis of hepatic encephalopathy is currently based on specific tests evaluating the neuropsychiatric state of patients and their quality of life; the severity of hepatic encephalopathy is measured by the West Haven criteria. Treatment of hepatic encephalopathy consists of pharmacological and corrective measures, as well as nutritional interventions. Rifaximin received approval for the treatment of hepatic encephalopathy in 2010 because of its few side effects and pharmacological benefits. The aim of this work is to review the use and efficacy of rifaximin both in acute and long-term management of hepatic encephalopathy. Treatment of overt hepatic encephalopathy involves management of the acute episode as well as maintenance of remission in those patients who have previously experienced an episode, in order to improve their quality of life. The positive effect of rifaximin in reducing health care costs is also discussed.Keywords: acute hepatic encephalopathy, recurrent hepatic encephalopathy, rifaximin, lactulose, cost, health-related quality of life

    The accuracy of measurement of the functional hepatic volume by single photon emission computed tomography (SPECT) with 99m Tc-galactosyl serum albumin ( 99m Tc-GSA) was evaluated. 99m Tc-GSA planar scintigraphic images were obtained dynamically and the hepatic SPECT imaging was then performed in 25 patients with hepatobiliary tumors. The patients were divided into 4 groups with normal hepatic function, mild, moderate and severe hepatic dysfunction. The functional hepatic volume determined by SPECT was compared with the morphological hepatic volume determined by computed tomography. The ratio of the hepatic volumes obtained by the two methods was calculated. The mean hepatic volume ratio was 96.6±2.3% in the normal hepatic function group and 95.9±2.2% in the mild dysfunction group (n.s.). In both the moderate and severe hepatic dysfunction groups, the hepatic volume ratio was smaller than that in the normal group (87.9±5.2%, p 15 (r=0.83, p 15 (r=0.74, p 15 (r=0.75, p 99m Tc-GSA faithfully reflects the functioning hepatocyte mass. 99m Tc-GSA scintigraphy and hepatic SPECT therefore provide information regarding global and regional reserve hepatic function.

    Hepatic surgery has been performed on condition that the liver regenerates after hepatic resection, and the development of liver anatomy due to Glisson, Rex, and Couinaud has thrown light on hepatic surgery Understanding of feeding and drainage vessels became feasible for systemic hepatic resection; however, it seems to have been the most important problem to control the bleeding during hepatic resection. New types of devices such as cavitron ultrasonic surgical aspirator (CUSA) and Microwave coagulation were exploited to control blood loss during hepatic surgery. Pringle maneuver for exclusion feeding vessels of the liver and the decrease of central venous pressure during anesthesia enabled further decrease of blood loss. Nowadays, 3D-CT imaging may depict feeding and drainage vessels in relation to liver mass, and surgeons can simulate hepatic surgery in virtual reality before surgery, allowing hepatectomy to be performed without blood transfusion. Thus, hepatic resection has been a safe procedure, but there's been a significant research on how much of the liver can be resected without hepatic failure. A prediction scoring system based on ICGR15, resection rates, and age is mostly reliable in some criteria. Even if hepatectomy is performed with a good prediction score, the massive bleeding and associated infection may induce postoperative hepatic failure, while the criteria of postoperative hepatic failure have not yet established. Hepatic failure is supposed to be induced by the apoptosis of mature hepatocytes and necrosis originated from microcirculation disturbance of the liver. Prostaglandin E1 for the improvement of microcirculation, steroid for the inhibition of cytokines inducing apoptosis, and blood purification to exclude cytokines have been tried separately or concomitantly. New therapeutic approaches, especially hepatic regeneration from the stem cell, are expected. (author)

    Full Text Available Fulminant hepatitis (FH is a life-threatening liver disease characterised by intense immune attack and massive liver cell death. The common precore stop codon mutation of hepatitis B virus (HBV, A1896, is frequently associated with FH, but lacks specificity. This study attempts to uncover all possible viral nucleotides that are specifically associated with FH through a compiled sequence analysis of FH and non-FH cases from acute infection. We retrieved 67 FH and 280 acute non-FH cases of hepatitis B from GenBank and applied support vector machine (SVM model to seek candidate nucleotides highly predictive of FH. Six best candidates with top predictive accuracy, 92.5%, were used to build a SVM model; they are C2129 (85.3%, T720 (83.0%, Y2131 (82.4%, T2013 (82.1%, K2048 (82.1%, and A2512 (82.1%. This model gave a high specificity (99.3%, positive predictive value (95.6%, and negative predictive value (92.1%, but only moderate sensitivity (64.2%. We successfully built a SVM model comprising six variants that are highly predictive and specific for FH: four in the core region and one each in the polymerase and the surface regions. These variants indicate that intracellular virion/core retention could play an important role in the progression to FH.
