输血后肝炎病例中丙型肝炎的分析 总被引:2,自引:0,他引:2
73例输血后肝炎经血清学检测,乙型肝炎病毒表面抗原和/或抗HBc阳性21例,抗丙型肝炎病毒抗体阳性62例,显示输出后肝炎以丙型肝炎为主,在62例输后血丙肝中,82.26%的患者输血或输血浆后6个月血清抗HCV阳转;输血血组与输血浆组比较,输注量与输血后丙型肝炎的发生无关。提示血浆比全血更易传播丙型肝炎。部分随访病例说明丙型肝炎慢性化趋势较高。 相似文献

Objective: This study aimed to explore clinical and virological characteristics of chronic hepatitis B (CHB) patients with hepatic steatosis in order to provide a theoretical basis for the prevention and control of hepatic steatosis.Methods: A total of 360 CHB inpatients were recruited from Affiliated Dongnan Hospital of Xiamen University and divided into hepatic steatosis group and non- hepatic steatosis group. The body mass index (BMI), waist-to-hip ratio (WHR), fasting blood glucose (FBG), triglyceride (TG), total cholesterol (TC), aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGT), hepatitis B e antigen (HBeAg), hepatitis B virus DNA (HBV DNA) and hepatic histological changes were detected and compared between the two groups. The association of these factors with hepatic steatosis was evaluated in CHB patients.Results: BMI, FPG, TG, TC, GGT, AST and HBV DNA showed statistically significant differences between two groups (P<0.01). The patients with hepatic steatosis had markedly higher BMI, FBG, TG and TC than those without steatosis did. No significant differences were found in ALT and HBeAg between two groups (P>0.05). In male patients, there was marked difference in the WHR between two groups (P < 0.01), which was not found in female patients (P > 0.05). The severity of hepatic steatosis increased in patients with hepatic steatosis, compared to those without steatosis (P < 0. 01), but the severities of inflammation and fibrosis in the non-hepatic steatosis group were dramatically higher than those in the hepatic steatosis group (P < 0. 01).Conclusions: BMI, WHR, FBG, TG and TC appeared to be influencing factors of CHB combined with hepatic steatosis. Hepatic steatosis in CHB patients was closely related to changes in anthropometric indices and metabolic factors but not HBV. It is necessary to improve these factors to effectively prevent hepatic steatosis in CHB patients. 相似文献

Purpose: Identification of hepatitis C virus (HCV) genotypes is very important in the selection of antiviral treatment, dose adjustment of antiviral agents, determining the treatment duration and following-up of treatment response. We aimed to determine the distribution pattern of HCV genotypes in chronic hepatitis C infection (CHC) patients. Materials and Methods: We have included 106 CHC patients who were positive in the anti-HCV and HCV-RNA tests performed in our hospital during the 16-month period. Anti-HCV assays were performed on device using a chemiluminescent microparticle immunoassay, while HCV-RNA tests and HCV genotyping assays were performed by real-time polymerase chain reaction. Results: Of the 106 cases; genotype 1b was detected in 67.0%, genotype 3 was detected in 16.0%, genotype 1a was detected in 14.2% and genotype 2 was detected in 2.8% patients. Genotypes 4, 5 and 6 were not detected in our study group. There were no statistically significant differences between the gender and age groups according to the HCV genotype distribution. The genotype 3 detection rate (16%) was the highest rate among the studies compared with the other studies in our country. Conclusions: Events that cause social changes such as war and immigration and intense commercial and touristic activities affect and alter the HCV genotype distribution in HCV-infected patients. For this reason, further multicentre studies are required reflecting all the regions in order to determine the genotype distribution in HCV-infected patients at regular intervals. 相似文献

Patients on maintenance hemodialysis (HD) are at increased risk of infection with hepatitis C virus (HCV). A prospective follow-up study on HCV infection from November 1999 to February 2003 was conducted in nine hemodialysis (HD) units in Hiroshima. A total of 2,744 HD patients were surveyed regularly for HCV RNA in serum. The prevalence of HCV RNA decreased from 15.7% (262/1,664) on the first survey to 12.9% (242/1,882) in the last one (P<0.05). This decrease may be attributed to the inclusion of patients with a lower prevalence of HCV RNA compared to patients leaving dialysis centers (111/1,080 [10.3%] vs. 132/862 [15.3%], P<0.01). During the 40 months of this study, 16 de novo HCV infections were documented in the nine HD units corresponding to an incidence of 0.33% per year. These cases included eight new HCV infections, three re-infections, and five infections that presumably occured in the window period when tested during the first survey. Our study shows that the annual incidence of de novo HCV infection during HD was 0.33%, and emphasizes the need for frequent serum HCV RNA testing and for stringent disinfection procedures in order to prevent the transmission of HCV in these settings. 相似文献

Hepatitis, a significant cause of mortality worldwide, results in around 1.34 million deaths each year globally. Africa is not exempt from the plague of Hepatitis. Around 100 million estimated individuals are infected with Hepatitis B or C. Egypt has the highest prevalence of cases of Hepatitis followed by Cameroon and Burundi. The continent is severely affected by the onset of the COVID-19 pandemic, as the virus has added an additional burden on the already fragile continent. With the pandemic, it is presumable that Hepatitis like other viral diseases will pose a threat to collapsing healthcare system. Therefore, for Africa to become more resilient in the face of such menaces, including Hepatitis, further prevention policies are required to be implemented 相似文献

One hundred and seven patients with acute viral hepatitis (AVH) were studied prospectively regarding the viral aetiological agent HAV, HBV and NANB (by exclusion) using radioimmunoassay. Acute HAV infection occurred in 43 patients, and acute HBV infection in 34 patients, while HDS occurred in two patients only. Acute, presumably NANB, infection occurred in 28 patients. Ten out of 28 sera of patients with AHBV infection were positive for smooth muscle antibody by immunofluorescence. Important findings include: (1) presence of delta superinfection in the absence of HBsAg; (2) HBsAg as the only marker in two patients with AHBV infection; (3) concurrent presence of HBsAg and anti-HBsAg in three patients with AHBV infection. 相似文献

To our knowledge, there are no published data on hepatitis C virus (HCV) genotypes in Angola. This study aimed at assessing the distribution of HCV genotypes in seropositive hemodialysis patients in Luanda. Among 51 HCV-positive subjects included, viremia was detected in 27 (53%). HCV genotyping was performed by bidirectional sequencing of the 5'-untranslated region by the Sanger method. HCV genotype 4 was largely predominant (20 cases; 74%), followed by genotypes 1b (5 cases; 18.5%), 1a and 2 (one case each; 3.7%). These results suggest that the distribution of HCV genotypes in Angola is similar to that reported from other Central African countries. 相似文献
