During a year an overall serological examination of 1,200 children hospitalized with the diagnosis of viral hepatitis was carried out with a view to establish the presence of hepatitis A and hepatitis B markers (anti-HAV IgM, HBsAg, anti-HBs, anti-HBc and anti-HBe IgM) by means of the enzyme immunoassay and radioimmunoassay. The average annual proportion of cases of hepatitis A (61.4%), hepatitis B (20.4%), hepatitis non A, non B (11.2%) and mixed infection (7.0%) among children, as well as seasonal and age-group fluctuations of this proportion, were established. The etiological structure of viral hepatitides, based on commonly accepted clinico-epidemiological diagnostic criteria, was shown to differ from their true etiological structure as determined in accordance with specific serological markers detected in this investigation. 相似文献

The results of epidemiological, clinical and laboratory studies revealed that the sharp rise of morbidity in viral hepatitides in Osh Province, the Kirghiz SSR in autumn 1987 was caused by hepatitis non A, non B virus with fecal-oral transmission. At this period the results of the enzyme immunoassay showed the absence of the markers of hepatitides A, B and Delta in 72.2% of viral hepatitis patients. Hepatitis non A, non B occurred only in 2.4% of viral hepatitis patients of preschool age (of these, 83.3% had hepatitis A) and was diagnosed in autumn 1987 in 50% of the patients aged 7-14 years and in 97.4% of the patients aged 15-29 years (in the latter age group 95-98% of the patients had IgG to hepatitis A virus in their blood). The appearance of the outbreak of the above-mentioned infection in Kirghizia is linked with the water route of the transmission of the infective agent. The epidemiological and clinical signs, characteristic of fecal-oral hepatitis non A, non B in Kirghizia, were not different from those registered earlier in other republics of the Central Asia and could be used for the identification of this infection. 相似文献

The etiological structure of viral hepatitides (VH) in one of the towns of the Gorky region was studied with the use of specific methods for diagnosing hepatitis A (detection of IgM to hepatitis A virus) and hepatitis B (detection of HBsAg in the passive hemagglutination test). The study revealed that hepatitis A was the major nosological from in the structure of VH among children and adults in the area under survey, which was documented by the detection of IgM to hepatitis A virus. The form, second in importance among VH cases, was hepatitis B. The ratio of these two forms of VH was determined by the epidemiological situation in the area. The proportion of hepatitis B cases increased at the period between epidemics. Nondifferentiated hepatitis constituted 6.8% of all cases of sporadic hepatitis among adults. In 90% of cases clinical diagnosis coincided with the serological one. 相似文献

A survey for the presence of markers of viral hepatitis B, delta, C and E among different groups of the population of the arctic and agricultural zones of the Republic of Sakha (Yakutia), as well as in Yakutsk, was carried out. The survey revealed that viral hepatitides with the parenteral mechanism of the transmission of infective agents were widely spread among the population. In the arctic zone HBsAg was detected in persons aged 20 years and older in 10.8-17.1% of cases. On the average, in the arctic zone antibodies to virus delta were detected in 2.4% of cases. In different regions of the agricultural zone the detection rate of HBsAg was also high (10.4-23.8%). In the Namsk and Vilyui regions delta infection was registered among adolescents (15-19 years of age) in 8.7 and 22.4% of cases respectively. In the Mountainous region anti-delta antibodies were detected among persons aged 20 years and older in 31% of cases. The survey showed the presence of considerable differences in the detection rate of the markers of hepatitis B, depending on the ethnic origin of the examined patients. Similar tendencies were found to exist with respect to delta infection. 相似文献

The determination of markers of virus hepatitides B, C and D in 63 registered HIV-infected persons was made. The use of Russian and foreign EIA systems permitted the detection of markers of virus hepatitides 30.1% of HIV-infected persons, including 26.3% of children. Markers of hepatitis B virus were found to occur in children and adults with the same frequency. Out of 65 persons registered in the Center, 3 persons (4.6%) were drug addicts; of these, 2 were found to have antibodies to antigens of hepatitis viruses. Such persons constituted 3.8% of the total number of HIV-infected persons. Among 8 newly detected and registered HIV-infected adults, 2 were found to have antibodies to hepatitis B virus (of these, 1 used drugs intravenously). 相似文献

The etiological structure of viral hepatitides in three cities of the Volga region was studied. The proportion of hepatitis non A, non B was established: it varied from 3.6% to 18.1% at different territories and depended on the total morbidity level, on the season, as well as on the age of patients. A suggestion was made concerning the role of the parenteral mechanism of the transfer of hepatitis non A, non B at the territory under study. 相似文献

Official annual statistical data on morbidity in acute viral hepatitides (AVH), including the number of lethal cases, for 1985-1995 were analyzed. Mortality rates per 100,000 of the population at the period of 11 years were calculated for different age groups, sex and the place of residence. 396 and 99 patients were examined for the presence of serological markers of hepatitides A, B and E, respectively, at the periods of epidemic rises in morbidity and satisfactory epidemic situation. In the course of 11 years AVH caused the death of 22,405 persons. In 1985-1987 the average mortality level (ML) reached 12.3-17.8 per 100,000 of the population (with morbidity being 1,200-1,400 and was essentially higher among the rural population in comparison with the urban population. During these years the highest ML, was registered among children aged 0-2 years (190-50 per 100,000) and, among adults, mainly among women aged 20-29 years (21.4-19.6 per 100,000). During the years when the epidemic of AVH was absent, ML among these groups was essentially lower: 40-20 among children aged 0-2 years and 4-5 among women aged 20-29 years. In 1987 in the Fergana Valley hepatitis E was detected in 72.2% of all examined patients, and in the southern areas of the country in 68.7%. A sharp rise on mortality among women of the productive age at the period of the epidemic rise of AVH morbidity in the endemic region indicated that this epidemic was linked with hepatitis E. High ML among young children may be indicative of a highly unfavorable course of hepatitis E in the group of infants, which had never been registered before. This newly established regularity may be used for the retrospective diagnostics of the outbreak of hepatitis E. 相似文献

Blood serum samples from 1,087 patients with acute viral hepatitis were studied. HBsAg was detected in 36.6% of cases. The study of anti-HBc IgM made it possible to diagnose hepatitis B in 6.6% of cases. The study of blood serum samples from 362 donors, 2,356 pregnant women and 163 medical workers in Rustavi for the presence of the markers of hepatitis B infection revealed a wide spread of hepatitis B in Rustavi. 相似文献

OBJECTIVE: To evaluate the prevalence of antibodies to hepatitis C virus and serological markers for hepatitis B virus infection in patients with HIV. DESIGN: Cross sectional survey. SETTING: Aquitaine, southwestern France, 1991-94. SUBJECTS: 1935 HIV positive patients seen at least once since June 1991. MAIN OUTCOME MEASURES: Presence of antibodies to hepatitis C virus were detected by second or third generation enzyme linked immunosorbent assay (ELISA) and recombinant immunoblot assay (RIBA) and markers for hepatitis B virus detected by ELISA. RESULTS: The prevalence was 42.5% (823) for antibodies to hepatitis C virus, 56.4 (507) for antibodies to hepatitis B core antigen, 6.9% (133) for hepatitis B surface antigen, 30.2% (584) for antibodies to hepatitis B core and surface antigen with no detectable surface antigen, 26.2% (507) for antibodies to core antigen only, and 4.8% (92) for antibodies to surface antigen only. The prevalence of antibodies to hepatitis C virus was 86.1% (726/843) in subjects who had bloodborne HIV infection and 7.3% (66/899) in those with sexually acquired infection. The prevalence of markers for hepatitis B was higher among homosexuals than in the other groups of patients, except for antibodies to surface antigen alone. The relation between markers for hepatitis B and hepatitis C virus was negative among men but positive among women. CONCLUSIONS: The results favour the hypothesis that hepatitis C virus is sexually transmitted much less commonly than either HIV or hepatitis B virus. 相似文献

Sera of 426 adult persons were examined to assess the prevalence of SEN virus (SENV) infection in Slovakia and to determine the importance of different risk factors for parenteral transmission. SENV prevalence was determined by the PCR method using primers of SENV-D and SENV-H strains. Positive results were found in 10 of 37 patients with acute hepatitis of unknown etiology, 7 of 38 with acute hepatitis B, 17 of 44 with chronic hepatitis B, 29 of 102 with chronic hepatitis C, 36 of 72 hemodialysis patients, 2 of 33 health care workers and 24 of 100 persons from the control group. The highest prevalence of SENV was among hemodialysis patients, significantly higher than in the groups of health care workers, acute hepatitis B and controls. The lowest prevalence was in health care workers group, significantly lower also in comparison with groups of chronic hepatitis B and C. Among the possible risk factors of virus transmission the average duration of hemodialysis (1.15 vs. 0.50 years), number of surgeries (1.60 vs. 1.10) and transfusions (1.34 vs. 0.94) showed notable differences in terms of SENV infection. Bilirubin and aminotransferase levels did not differ between SENV-positive and -negative groups. No pathogenetic role of SEN virus in liver injury was confirmed. 相似文献

Background
Human immunodeficiency virus (HIV) infection and acquired immune deficiency syndrome (AIDS) cause serious health problems and have an impact on the Indonesian economy. In addition, the rapid epidemic growth of HIV is continuing in Indonesia. Commercial sex plays a significant role in the spread of HIV; therefore, in order to reveal the current HIV prevalence rate among commercial sex workers (CSWs), we conducted an epidemiological study on HIV infection among CSWs residing in Surabaya, the capital of East Java province of Indonesia with large communities of CSWs.Methodology/Principal Findings
The prevalence of HIV infection among 200 CSWs was studied. In addition, the subtype of HIV type 1 (HIV-1) and the prevalence of other blood-borne viruses, hepatitis B virus (HBV), hepatitis C virus (HCV) and GB virus C (GBV-C), were studied. The prevalence rates of HIV, hepatitis B core antibody, hepatitis B surface antigen, anti-HCV antibodies and anti-GBV-C antibodies were 11%, 64%, 4%, 0.5% and 0% among CSWs involved in this study, respectively. HIV-1 CRF01_AE viral gene fragments were detected in most HIV-positive samples. In addition, most CSWs showed low awareness of sexually transmitted diseases and had unprotected sex with their clients.Conclusions/Significance
The HIV prevalence rate among CSWs was significantly higher than that among the general population in Indonesia (0.2–0.4%). In addition, CSWs were at a high risk of exposure to HBV, although chronic HBV infection was less frequently established. Our results suggest the necessity of efficient prevention programs for HIV and other blood-borne viral infections among CSWs in Surabaya, Indonesia. 相似文献12.
Information on viral hepatitis A, B and C morbidity in Russia is presented. A distinct trend to decreased viral hepatitis B and C morbidity in 2001-2002 in comparison with the 1990-ies is noted. Nevertheless, there is still unfavorable prognosis regarding high hepatitis B morbidity among the population of reproductive age, as well as among adolescents, which increases the risk for children at an early age. In addition, a new specific feature of hepatitis A spread is observed: morbidity in this infection is shifted to older age groups. The role of vaccinal prophylaxis in the decrease of hepatitis A and B morbidity, virus safety of blood and its components, the quality of the diagnostics of chronic hepatitis, especially hepatitis C, are discussed. The complex of measures for the prophylaxis of viral hepatitis is proposed. 相似文献

In this cross-sectional study, 207 hepatitis B surface antigen
(HBsAg)-negative kidney transplant recipients were evaluated based on
demographic and epidemiological data and on the levels of serological markers of
hepatitis B virus (HBV) and hepatitis C virus infection and liver enzymes.
Patients with HBV or human immunodeficiency virus infection were excluded. Sera
were analysed for the presence of HBV-DNA. HBV-DNA was detected in two patients
(1%), indicating occult hepatitis B (OHB) infection (the HBV-DNA loads were 3.1
and 3.5 IU/mL in these patients). The results of the liver function tests were
normal and no serological markers indicative of HBV infection were detected. The
prevalence of OHB infection was low among kidney transplant recipients, most
likely due to the low HBsAg endemicity in the general population of the study
area. 相似文献

611 patients with acute parenteral virus hepatitis (VH) were studied with a view to find out markers indicating the presence of hepatitis B and hepatitis C virus infection (HB, HC, HB + C, HC + HBsAg). Of these, 166 patients (27.2%) systematically used narcotic drugs intravenously. Essential differences between drug users and VH patients without drug addiction were established regarding the distribution of patients by age and sex, the etiological structure and severity of the disease. Thus, in the group of drug users the prevalence of males, young people (15-29 years of age) and the mixed form of hepatitis B + C was noted. In VH patients using drug the disease took a more severe course than in such patients without drug addiction. The highest proportion of intravenously drug users with a severe and moderate course of the disease was found among patients with HB + C and HB. 相似文献

During recent 10 years (1990-1999) essential changes occurred the epidemiology of viral hepatitis A (VHA) in Estonia: simultaneously with a decreased level of morbidity (morbidity rate per 100,000 of the population was 78.4 in 1990 and 7.7 in 1996, or 1,241 and 112 cases, respectively), a shift in the age structure of patients from children of preschool age to older age groups took place. Everyday contacts were the main established route of VHA transmission in recent years, but in more than 80% of cases the risk factors of the virus transmission remained obscure. During the regional outbreak of VHA in North Estonia in 1998 (937 out of 989 cases registered in the country) a rise in morbidity was observed among young people aged 15-29 years, when a wide spread of parenteral viral hepatitides B and C and drug addiction were registered in this region. During this outbreak VHA was transmitted mainly through everyday contacts. Still the considerable prevalence of injection drug users who practiced the group use of syringes and needles and took drugs from common containers, a sufficiently high level of the mixed forms of the disease (more than 18% of all registered cases of VHA), detected for the first time, make it possible to suggest that the parenteral transmission route could appear among persons belonging to the above mentioned group. Vaccination is regarded as the most effective measure for the prophylaxis of VHA. 相似文献

A seroprevalence study was carried out among a group of women in Rio de Janeiro to determine the prevalence of different markers for viral hepatitis given the limited data among healthy populations. Blood samples collected and tested from 874 women before or after delivery in a public county maternity hospital demonstrated age to be directly related to markers for hepatitis A virus and hepatitis B virus (HBV) infection. The prevalence of HBV and hepatitis C virus infection were lower than that observed in the blood donor population and might be explained by the younger age group and gender. 相似文献

A survey was conducted in the hemodialysis population of the state of Tocantins, Brazil, aiming to assess the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, to analyze associated risk factors, and also to investigate these viruses genotypes distribution. During January and March 2001, all patients (n = 100) were interviewed at the unique dialysis unit in Tocantins. Blood samples were collected and serum samples were screened for HBV serological markers. Hepatitis B surface antigen positive samples were tested for HBV DNA. All samples were also tested for anti-HCV antibodies and HCV RNA. An overall prevalence of 45% was found for HBV infection (4% were HBsAg/anti-HBc positive, 2% were anti-HBc only and 39% had anti-HBc/anti-HBs markers). Concerning HCV infection, anti-HCV and HCV RNA were detected in 13% and 14% of the subjects, respectively. Three patients were HCV RNA positive and anti-HCV negative, resulting in an overall HCV prevalence of 16%. Univariate analysis of risk factors showed that only shift and length of tile on hemodialysis were associated with HBV and HCV positivity respectively. Among the four HBsAg-positive samples, HBV DNA was detected in three of them, which were identified as genotype A by restriction fragment length polymorphism (RFLP) analysis. All 14HCV RNA-positive samples were genotyped by INNO-LiPA. Genotypes la and 3a were found in 85% and 15%, respectively. The present data show low HBsAg and HCV prevalence rates. The risk factors associated with HBV and HCV positivity suggest that nosocomial transmission may influence in spreading these viruses in the dialysis unit studied. 相似文献

The dynamic study of 198 patients having virus hepatitides B and C was carried out. The etiological diagnosis in these patients had been made on the basis of serological investigation and the determination of markers with the use of the polymerase chain reaction. The manifestations of the disease were compared in 98 drug addicts and 100 patients stating they used no drugs. In addicts practicing the parenteral introduction of drugs acute virus hepatitides took, in most cases, the moderate course with the pain syndrome in the liver, abstinence symptoms, hepatomegaly, the elevated level of ALT in the blood. The convalescence period is characterized by the prolonged course with the slow restoration of the liver function. 相似文献

The spread of viral hepatitides on the territory of Central Asia has been analyzed, taking into account regional and territorial factors and using the Fergana Valley as an example. The analysis, based on the use of modern immunochemical, clinico-epidemiological and biochemical criteria, has made it possible to determine the etiological structure of viral hepatitides on the territory of the Fergana Valley. The epidemic outbreak on this territory has been proved to be caused by viral hepatitis E. The necessity of organizing constant epidemiological monitoring on the interstate and territorial level has been substantiated. 相似文献
