Abstract
Saliva may be an alternative biological specimen to expand HCV detection. This study aims to evaluate an in-house quantitative RT-PCR for HCV RNA quantification in saliva. A total of 80 individuals (56 anti-HCV/HCV RNA + and 24 negative controls) donated serum and saliva, that were tested using an in-house quantitative PCR for HCV RNA. The median viral load was 4.77 log10 copies/mL (1.04-7.0 log10 copies/mL) in serum and 2.31 log10 copies/mL (1.0-3.84 log10 copies/mL) in saliva. A sensitivity and specificity of 80 % was observed for HCV detection in saliva, which demonstrates the usefulness of in-house real-time PCR to quantify HCV RNA in saliva samples, which might increase the access of molecular diagnosis of HCV in laboratories that lack complex infrastructures for molecular testing and in individuals with poor venous access.

Abstract
Hepatitis C virus (HCV) RNA can be detected in body fluids such as urine. However, because of deficiencies in established isolation and detection methods, the actual prevalence and form of HCV RNA in the urine of patients with hepatitis C remain unclear. To more sensitively and accurately measure urine HCV RNA levels, a novel real-time PCR assay with a modified isolation method and short amplicon designed for short HCV RNA fragments was developed in this study. The limit of detection, precision, linearity, and specificity of the assay was evaluated and demonstrated high-quality performance. The prevalence of HCV RNA in the urine of viremic patients infected with HCV was 60% (36/60), as determined by a 62-bp assay. The HCV RNA detection rate and concentration were much lower with a 157-bp assay, and were undetectable with 222- and 304-bp assays. With the 62-bp assay, patients with detectable urine HCV RNA had significantly higher plasma HCV RNA levels ( P < 0.001), and plasma and urine concentrations were significantly positively correlated ( R 2 = 0.708, P < 0.001). The method not only increased the detection rate of urine HCV RNA but also revealed the presence of short HCV RNA fragments in urine, indicating that urine from CHC patients with normal kidney function should not be infectious. In addition, it raised the possibility of urinary HCV RNA as a potential noninvasive marker for therapeutic monitoring of patients with hepatitis C.

Abstract
BACKGROUND & AIMS Hepatitis E virus (HEV) is known to be excreted in the stool but there has been no report of its presence in urine. This study investigated the presence of HEV RNA and antigen (HEV-Ag) in urine and its possible transmission. METHODS Serum and urine samples from patients with chronic or acute HEV infection and HEV infected monkeys were tested for viral and biochemical markers. Liver and kidney biopsies from the infected monkeys were analyzed by histopathology and immunohistochemistry. The infectivity of HEV from urine was assessed by inoculation into monkeys. RESULTS HEV RNA and HEV-Ag were detected persistently in the urine of a patient with chronic HEV infection. Subsequently, HEV RNA was detected in the urine of three of the eight (37.5%) acute patients, all of whom had detectable HEV-Ag in their urine. HEV RNA and HEV-Ag were also detectable in the urine of HEV infected monkeys. The ratio of HEV-Ag to RNA in the urine of the infected monkeys was significantly higher than in their sera and feces. The parameters of routine urinalysis remained within the normal ranges in the hepatitis E patients and infected monkeys, however, pathological changes and HEV-Ag were observed in the kidneys of the infected monkeys. Furthermore, one of two monkeys became infected with HEV after inoculation with urine from another infected monkey. CONCLUSIONS HEV infection may result in kidney injury and the urine may pose a risk of transmission. HEV-Ag detection in urine may be valuable for diagnosis of ongoing HEV infection.

Abstract
PURPOSE To obtain aqueous humor and tear fluid samples during cataract surgery of the hepatitis C virus (HCV)-antibody-positive patients in order to analyze them for HCV RNA and compare these measurements with serum HCV RNA levels. METHODS Twenty-nine anti-HCV-positive patients were included this study. HCV RNA viral load levels were determined by commercial real-time polymerase chain reaction system. Antibodies to HCV were screened with the enzyme-linked immunosorbent assay (ELISA) using anti-HCV test kit. RESULTS Log10 HCV RNA levels were found to be 6.00 ± 1.06 IU/mL in serum, 2.76 ± 0.36 IU/mL in the aqueous humor, and 1.91 ± 0.93 IU/mL in tear fluid. No correlation was detected between samples for HCV RNA positivity (p = .390, κ = .102). We have observed that, viral RNA was detected in the aqueous humor, while not in serum in one case, whereas viral RNA was detected in tear fluid but not in serum in another case. CONCLUSIONS Although viral load detected in aqueous humor and tear fluid samples was considerably lower compared to the serum samples, it can still be important in terms of infectivity.

Detection of hepatitis C virus RNA in saliva of patients with active infection not associated with periodontal or liver disease severity. BMC Infect Dis 2014; 14:72. [PMID: 24512371 PMCID: PMC3925132 DOI: 10.1186/1471-2334-14-72] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2013] [Accepted: 02/03/2014] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND Hepatitis C virus (HCV) is mainly transmitted by parenteral route, being blood transfusion and intravenous drug use the most frequent risk factors. However, it has been suggested that there are other routes of transmission. There are several studies where HCV RNA has been detected in saliva of patients infected with HCV, and epidemiological studies have proposed the dental treatments as possible risk factors for HCV transmission. The purpose of this study was to detect the presence of HCV RNA in saliva of patients with active infection and associating with periodontal or liver disease. METHODS Patients with quantifiable HCV-RNA in serum were enrolled in the study. Periodontal disease was assessed using the modified gingival index (MGI). Presence of dental plaque was assessed with the use of disclosing tablets. Patients were clinically and laboratory evaluated to identify the stage of liver disease, the HCV RNA was determinate in saliva by nested RT-PCR. To determine associations between different parameters univariate and multivariate analysis were used. RESULTS A total of 45 patients were included. Of these patients, 21 (46.6%) had hepatitis, 23 (51.1%) had cirrhosis and one patient (2.4%) presented hepatocellular carcinoma (HCC). Viral loads in serum ranged from 2.31-6.68 log IU/ml with a mean of 5.46 log IU/ml (95% CI 5.23-5.70). HCV RNA was positive in saliva of 29 patients (64.4%) and was not detected in 16 (35.6%). For univariate analysis three independent variables were associated with the detection of HCV-RNA in saliva: gender, viral load and dental plaque and multivariate analysis only one independent variable viral load >5.17 log IU/mL remained significantly associated with the detection of HCV in saliva (p = 0.0002). A statistical difference was observed when viral load was analyzed, log 5.85 IU/mL (95% CI 5.67-6.02) for patients with HCV in saliva vs. log 4.77 IU/mL (95% CI 4.35-5.19) for patients without HCV in saliva (p = 0.0001). The detection of HCV-RNA in saliva was more frequent in patients with relatively high serum viral loads. CONCLUSION HCV-RNA in saliva was associated with the level of serum viral load but not with periodontal or liver disease severity.

Abstract
BACKGROUND An estimated 130-170 million people worldwide are chronically infected with HCV.(1) In Europe the highest prevalence of HCV infections is in the IDU population.(2) As traditional HCV screening relies on the detection of HCV antibody or HCV RNA in blood, screening in high-risk groups such as IDU is difficult due to poor venous access caused by damaged veins. OBJECTIVES In this study DBS was evaluated as an alternative sample type to blood for the detection of HCV RNA. STUDY DESIGN The endpoint detection limit, inter-assay and intra-assay variability of the method were determined. The DBS method was compared to our routine frontline assay using a panel of paired DBS and blood samples. The effect of different storage temperatures and length of storage time on the stability of HCV RNA in DBS was also assessed. RESULTS The endpoint detection limit of the method based on results from mock DBS was 250 IU/ml. The method was shown to be precise and robust. The sensitivity and specificity of the method was found to be 100% and 95.8%, respectively. No significant variation in the stability of HCV RNA in DBS over a 1 year period at a range of different temperatures was observed. CONCLUSIONS A sensitive and stable method was developed for the detection of HCV RNA in DBS. Screening high-risk populations using DBS as a sample type may improve uptake of HCV testing by increasing opportunity for patients to be tested and consequently increasing access to treatment.

Abstract
BACKGROUND AND AIMS Viral hepatitis is a significant global health problem that, depending upon the virus, affects individuals of the developing and/or developed world. In recent years, there has been renewed interest in whether oral fluids can be considered as a source of viral hepatitis transmission and whether oral fluid, in particular, whole saliva, may be a useful source for viral detection as part of the diagnosis and monitoring of viral hepatitis. The aim of this article was to review current data concerning the possible carriage of the hepatitis A, B and C viruses within saliva and gingival crevicular fluid. Such knowledge will indicate if (i) oral fluid is a possible source of infection and (ii) whether oral fluid can be used for diagnosis and monitoring of viral hepatitis. DATA AND SOURCES A literature search was conducted using PubMed (Medline), EMBASE/Excerpta medica, the Cochrane database and Scopus. The results were limited to published material after 2000. Relevant material was evaluated and reviewed. CONCLUSION There is some evidence that hepatitis viruses A, B and C are present in oral fluids, particularly whole saliva and gingival crevicular fluid and may thus be possible sources of viral detection in clinical diagnosis and monitoring. However, the data are inconsistent and warrant the need for well-planned longitudinal studies to explore the precise frequency of oral carriage of such viruses and to determine the virological and host factors that may influence the oral presence of hepatitis A, B and C viruses.

Abstract
BACKGROUND Hepatitis C can lead to liver fibrosis and cirrhosis. We compared readily available non-invasive fibrosis indexes for the fibrosis progression discrimination to find a better combination of existing non-invasive markers. METHODS We studied 157 HCV infected patients who underwent liver biopsy. In order to differentiate HCV fibrosis progression, readily available AAR, APRI, FI and FIB-4 serum indexes were tested in the patients. We derived a new fibrosis-cirrhosis index (FCI) comprised of ALP, bilirubin, serum albumin and platelet count. FCI = [(ALP × Bilirubin) / (Albumin × Platelet count)]. RESULTS Already established serum indexes AAR, APRI, FI and FIB-4 were able to stage liver fibrosis with correlation coefficient indexes 0.130, 0.444, 0.578 and 0.494, respectively. Our new fibrosis cirrhosis index FCI significantly correlated with the histological fibrosis stages F0-F1, F2-F3 and F4 (r = 0.818, p < 0.05) with AUROCs 0.932 and 0.996, respectively. The sensitivity and PPV of FCI at a cutoff value < 0.130 for predicting fibrosis stage F0-F1 was 81% and 82%, respectively with AUROC 0.932. Corresponding value of FCI at a cutoff value ≥1.25 for the prediction of cirrhosis was 86% and 100%. CONCLUSIONS The fibrosis-cirrhosis index (FCI) accurately predicted fibrosis stages in HCV infected patients and seems more efficient than frequently used serum indexes.
