ABSTRACT

Hepatitis E virus (HEV) infection has a worldwide distribution and represents an important cause of acute hepatitis. This study aims to investigate the occurrence of HEV infection and factors associated with this infection in patients with acute non-A, non-B, non-C hepatitis in Central Brazil. From April 2012 to October 2014, a cross-sectional study was conducted among 379 patients with acute non-A, non-B, non-C hepatitis in the City of Goiania, Central Brazil. Serum samples of all patients were tested for serological markers of HEV infection (anti-HEV IgM and IgG) by ELISA. Positive samples were confirmed using immunoblot test. Anti-HEV IgM and IgG positive samples were tested for HEV RNA. Of the 379 serum samples, one (0.3%) and 20 (5.3%) were positive for anti-HEV IgM and IgG, respectively. HEV RNA was not found in any sample positive for IgM and/or IgG anti-HEV. After multivariate analysis, low education level was independently associated with HEV seropositivity (p = 0.005), as well as living in rural area, with a borderline p-value (p = 0.056). In conclusion, HEV may be responsible for sporadic self-limited cases of acute hepatitis in Central Brazil.

ABSTRACT

@#Twelve compounds were isolated and purified from ethyl acetatefraction of Cynanchum stauntonii by silica gel, Sephadex LH-20 and ODS column chromatography. Their structures were identified by spectral techniques and physicochemical properties as syringaresinol(1), (-)-(7R, 7′R, 7″R, 8S, 8′S, 8″S)-4′, 4″-dihydroxy-3, 3′, 3″, 5-tetramethoxy-7, 9′ ∶7′, 9-diepoxy-4, 8″-oxy-8, 8′-sesquineolignan-7″, 9″-diol(2), prinsepiol(3), 4-hydroxyacetophenone(4), baishouwubenzophenone(5), 2, 4-dihydroxyacetophenone(6), benzoic acid(7), 1, 4-benzenediol(8), 6-O-[E]-sinapoyl-α-D-glucopyranoside(9a), 6-O-[E]-sinapoyl-β-D-glucopyranoside(9b), 1-O-methyl-α-D-cymadropyranoside(10), β-daucosterol(11), and β-sitosterol(12). Compounds 1-3, 5 and 7-11 were firstly isolated from this plant.

ABSTRACT

Totally 56% of occurrence was observed from 6 types of sources. Among them highest prevalence was observed from urinary catheter (68%) next in line is intravenous tubes (66.66%), venflon needles (65%), and blood bags (53.33%) respectively. Four types of Candida species were identified by using selective media and biochemical tests. The Candida albicans was predominant isolates in all sources especially in urinary catheter. In this study, 60.2% of non Candida albicans were observed. All isolates were subjected to antifungal stability test, 6 antifungal agents were used. Among the 6 antifungal agents Itraconazole had highly resistance activity and Fluconazole had highly sensitive activity against the isolates. The antifungal resistance of isolates were highly observed in non Candida albicans such as Candida tropicalis (83.3%) and followed by Candida glabrata (74.5%). All isolates were have the ability to produce biofilm, among them 37.4% of isolates were strong biofilm producer and 100% of protease producing isolates were observed in the last part of the study.

ABSTRACT

Introduction: Hepatocellular carcinoma (HCC) is the most common primary malignant liver tumour, which commonly occurs in those with underlying chronic liver problems mainly cirrhoric liver with viral hepatitis (HBV and HCV) as the most common aetiological agent. HCC could also arise from non-chronic liver, which include non-B non-C (NBNC) hepatitis, which is different in pathogenesis, epidemiology and prognosis. This disease entity would include the commonly benign fatty liver leading to non-alcoholic steatohepatitis (NASH) and HCC as sequale. Methods: We present a case of non-B non-C HCC arising from a fatty liver in a non-alcoholic patient. Literature search was done with special emphasis on this disease. Conclusion: The incidence of NBNC HCC demonstrates an increasing trend, making it an important entity to be recognised early. A good understanding of this incidence would make it possible to predict the outcome, especially as the prognosis of non-B non-C HCC is fairly good if the HCC is found at an early stage

ABSTRACT

PURPOSE: Non-A, B, C viral hepatitis is the name given to the disease with clinical viral hepatitis, but in which serologic evidence of A, B, C hepatitis has not been found. Little is known about the etiology and clinical features of non-A, B, C viral hepatitis in children. METHODS: A clinical analysis of 45 cases with non-A, B, C viral hepatitis who were admitted to the Department of Pediatrics, Pusan National University Hospital, from January 2001 to June 2004 was carried out retrospectively. Patients who were positive for HBsAg, anti-HAV and anti-HCV and had toxic, metabolic, autoimmune, or neonatal hepatitis were excluded in this study. RESULTS: Among 45 cases of non-A, B, C viral hepatitis, the etiology was unknown in 26 (57.8%), CMV (cytomegalovirus) in 14 (31.1%), EBV (Epstein Barr virus) in 2 (4.4%), HSV (herpes simplex virus) in 2 (4.4%) and RV (rubella virus) in 1 (2.2%). Twenty seven out of 45 (60.0%) patients were under 1 year of age. Sixteen (33.3%) patients had no specific clinical symptoms and were diagnosed incidentally. On physical examination, twenty seven out of 45 patients (60.0%) had no abnormal findings. Forty three out of 45 patients (95.6%) showed classic clinical course of acute viral hepatitis, whereas fulminant hepatitis developed in two patients. Mean serum ALT (alanine aminotransferase) level was 488.7+/-771.9 IU/L. Serum ALT level was normalized in 31 out of 45 patients (81.6%) within 6 months and all patients within 18 months. Aplastic anemia was complicated in a case. CONCLUSION: Although most patients with non-A, B, C viral hepatitis showed a good prognosis, a careful follow-up would be necessary because some of them had a clinical course of chronic hepatitis, fulminant hepatitis and severe complication such as aplastic anemia.

ABSTRACT

BACKGROUND/AIMS: About 15% of Korean hepatocellular carcinoma (HCC) are negative both of Hepatitis B surface antigen (HBsAg) and anti-hepatitis C virus (anti-HCV) in their sera. They can be classified as a non-B, non-C hepatocellular carcinoma group (NBNC group). The aims of our study were, firstly, to describe the clinical characteristics of Korean NBNC HCC and compare them with those of HBsAg-positive HCC (HBV group) and anti-HCV-positive HCC (HCV group). Secondly we wanted to assess the frequency of viremia of HBV, HCV and transfusion-transmitted virus (TTV) in NBNC HCC patients. METHODS: We prospectively collected clinical data and sera from 113 NBNC HCC patients and performed PCR for HBV DNA, HCV RNA and TTV DNA. We also collected clinical data from 125 HBsAg-positive HCC patients and 61 anti-HCV-positive HCC patients during a similar period. RESULTS: The mean age of the NBNC HCC group was 59 years, in-between that of the HBV and the HCV groups. A History of heavy alcohol drinking was found in 48% of the NBNC HCC group. This was significantly higher than that of the HBV group, but similar to that of the HCV group. Serum alphaFP level in the NBNC HCC group was more frequently in the normal range compared to that in the HBV and HCV groups. The detection rates of HBV DNA, HCV RNA and TTV DNA in the NBNC HCC group were 17%, 13%, and 67% respectively. CONCLUSIONS: The NBNC HCC patients seemed to comprise a heterogeneous group of various etiologies and clinical presentations. About one third of these patients displayed evidence of viremia of HBV or HCV.
