Information is very scarce on the prevalence of hepatitis-B virus (HBV) infection among blood donors and patients with human immunodeficiency virus (HIV) infection in Nigeria. Hepatitis-B surface antigen (HBsAg) ELISA was used to determined the prevalence of HBsAg among 175 blood donors (aged 20-40 years) and 490 HIV-infected patients (aged 17-60 years) in Jos, Nigeria. Twenty-five (14.3%) of the blood donors and 127 (25.9%) of the HIV-infected individuals were HBsAg seropositive, indicating a higher HBV infection among HIV-infected persons than among healthy blood donors. A slightly higher HBsAg seroprevalence was recorded in the males (14.6%) than females (12.9%) of the blood donors. Among the HIV-infected patients, the males had considerably higher HBsAg seroprevalence than the females (31.8 vs 22.1%) with the highest prevalence of HBsAg occurring in the 51-60 years age group (44%), followed by those of 31-40 years (28.2%). Results confirmed the high endemicity of HBV infection in Jos, Nigeria and the significantly greater prevalence of HBV infection among HIV-infected patients than among blood donors. 相似文献

The main tendencies in the development of drug addiction in the Ukraine, the dynamics of the spread of HIV among drug addicts introducing drugs intravenously, epidemiological data on HIV, AIDS and drug addiction, as well as prognoses on the development of HIV infection are presented. Since 1995 the number of HIV-infected persons grew 34-fold, the number of cases of HIV infection resulting from the intravenous use drugs rose to 70% simultaneously with the rise (about 34-fold) of the number of persons infected with HIV through sexual contacts (about 13 fold). In 1996-1997 such tendency increased. On the whole, the proportion of drug addicts introducing drugs by intravenous injection was 83% in the Ukraine. By April 1, 1998, official registration covered 18,800 HIV-infected persons, including 270 foreign nationals, as well as 499 AIDS patients, including 487 Ukrainian citizens, among them 28 children. Out of 18,800 HIV-infected persons, 78.3% were drug addicts, most of them young people aged 15-30 years; about 18% were young people under 20 years of age, 80% being males. According to the model the rapid spread of HIV from the group of drug addicts to the heterosexual population, the total number of HIV-infected persons reaching 1,500,000 is expected in the country by 2014. 相似文献

The presence of the epidemic of drug addiction in the Russian Federation is stated: for the recent 10 years the number of drug addicts increased 3.5-fold. The questioning of several thousand drug addicts has revealed that 60% of them have hepatitis B, 80% have hepatitis C, 10% have syphilis. The strategy of controlling HIV infection among drug addicts is proposed. It includes, in the first place, the prevention of the secondary infection from HIV-infected addicts; in the second place, the detection of HIV-infected persons in groups of drug addicts, difficult to establish contacts with; in the third place, the primary prophylaxis within the program "Harm reduction" in the most susceptible groups of drug addicts. The thesis that the prevention of HIV infection must become the prevention of drug addiction by rendering multi-stage assistance to HIV-infected persons, including mainly drug addicts, is substantiated. 相似文献

The study was aimed at anti-interferon activity of different components of the in vitro system cells MT-4--HIV-1 as well as the culture fluid of peripheral blood leukocytes from patients at different stages of HIV infection and from patients with mixed infection (HIV and chronic hepatitis C) in comparison with patients infected with hepatitis C virus alone and healthy persons. Anti-interferon activity was detected in all groups of patients, its detection rate varying within 33% and 68%. The tendency towards increased detection rate of anti-interferon activity in HIV-infected patients in parallel with decreased number of CD4+ lymphocytes was noted. These data made it possible to suggest that increased detection rate of anti-interferon activity in the culture fluid of peripheral blood leukocytes from HIV-infected patients in parallel with decreased number of CD4+ lymphocytes could result from pathogenetic processes in the body, leading to a decrease in therapy effectiveness of HIV-infected patients with the preparations of alpha-interferon, especially in patients with a low content of CD4+ cells. 相似文献

The status of vitamin D in individuals infected with human immunodeficiency virus (HIV), particularly in naïve as well as treated patients, has never been reported in the Pakistani population. A cross-sectional study was performed to measure vitamin D in individuals infected with HIV living in various districts of the Punjab, Pakistan. 1000 persons attending various treatment centers of the Punjab were screened for HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), and Syphilis. Total 398 patients met inclusion criteria and vitamin D level was measured in respective cases by using enzyme-linked immunosorbent assay (ELISA) technique. 232 samples from the healthy population were also included in present research. Demographic history and clinical parameters regarding HIV disease were evaluated. Comparison of variables was done to find out the link between vitamin D levels and characteristics of HIV infected persons and comparison to that of healthy individuals was performed. Among 398 HIV patients vitamin D deficiency and insufficiency was found among 15 % and 39 % while majority of the control participants had sufficient levels of vitamin D (78 %). Most of the HIV infected individuals were males (68.6 %) and had age between 24 and 47 years (67.8 %). A significant relationship was found for vitamin D level, lifestyle and CD4 count among HIV + ve non acquired immunodeficiency syndrome (AIDS) subjects (95 % CI; p < 0.001, p = 0.09). For HIV + ve AIDS patients vitamin D had a significant relationship with lifestyle along with HIV viral load and CD4 count. Hypovitaminosis D prevails among the HIV infected population of Punjab, Pakistan. 相似文献

Diarrhea remains one of the major causes of death in Bangladesh. We studied diarrheal disease risk and healthcare seeking behavior among populations at high risk for diarrhea in Dhaka, Bangladesh. Data were obtained from a cross-sectional survey conducted during April and September 2010. The prevalence of diarrhea was calculated by age-group and sex. A generalized estimating equation with logit link function was used to predict diarrheal disease risk and seeking care from a professional healthcare provider. Of 316,766 individuals, 10% were young children (<5 years). The prevalence of diarrhea was 16 per 1000 persons among all ages; young children accounted for 44 per 1000 persons. Prevalence of diarrhea was significantly higher (p=.003) among younger males (<15 years) compared to that among younger females. In contrast, prevalence of diarrhea was significantly higher (p<.0001) among older females (≥15 years) compared to that among older males. An increased risk for diarrhea was observed in young children, males, and those staying in rented houses, lower family members in the house, using non-sanitary toilets, living in the area for short times, living in a community with less educated persons, living in a community with less use of safe water source for drinking, or living close to the hospital. About 80% of those with diarrhea sought care initially from a non-professional healthcare provider. Choice of the professional healthcare provider was driven by age of the patient, educational status of the household head, and hygienic practices by the household. The study reaffirms that young children are at greater risk for diarrhea. Like other developing countries most people in this impoverished setting of Dhaka are less likely to seek care from a professional healthcare provider than from a non-professional healthcare provider, which could be attributed to a higher number of diarrheal deaths among young children in Bangladesh. Dissemination of information on health education, increasing the supply of skilled healthcare providers, and low-cost and quality healthcare services may encourage more people to seek care from professional healthcare providers, thus may help reduce child mortality in the country. Further studies are warranted to validate the results. 相似文献

A total of 176 hospital patients with chronic hepatitis C (CHC), among them 110 males and 66 females, were examined. The spectrum of antibodies to four hepatitis C virus (HCV) proteins (core, NS3, NS4, NS5) and in 142 patients --IgM antibodies to HCV (anti-HCV IgM) were determined. In 92% of the CHC patients antibodies to core, NS3 and NS4 proteins were simultaneously detected. Differences in the detection of antibodies to HCV in males and females were not statistically reliable. In CHC patients aged up to 20 years anti-NS4 and anti-NS5 were less frequently detected. Among males of different age groups reliable differences in the detection rate of anti-NS5 were registered, while among females of different age groups no such differences were observed. With the increase of age these antibodies were detected somewhat more often. In females over 60 years anti-HCV IgM occurred more often than in males of the same age. The levels of alanine aminotransferase (ALT) were higher in persons with the presence of anti-NS5 and anti-HCV IgM than in persons with their absence. In all groups of CHC patients with biochemical activity and liver cirrhosis the detection rate of anti-HCV IgM was significantly higher than in patients with normal ALT activity. The antibody spectrum with the simultaneous absence of HCV IgM and anti-NS5, while found to contain antibodies to other HCV antigens, was registered significantly less frequently in patients with moderate and high CHC activity and the liver cirrhosis induced by HCV infection. 相似文献

BackgroundHepatitis C virus (HCV) infection has been increasingly recognized among HIV-infected men who have sex with men (MSM) worldwide. We investigated the trend of and factors associated with acute hepatitis C (AHC) among HIV-infected individuals in Taiwan.MethodsThe National Disease Surveillance System collects characteristics of AHC, HIV, syphilis, and gonorrhea cases through mandatory reports and patient interviews. Reported AHC patients in 2014 were interviewed additionally on sexual and parenteral exposures. Information on HCV genotypes were collected from the largest medical center serving HIV-infected Taiwanese. We defined an HIV/AHC case as a documented negative HCV antibody test result followed within 12 months by a positive test in a previously reported HIV-infected individual. Each case was matched to two HIV-infected, non-AHC controls for age, age of HIV diagnosis, sex, transmission route, HIV diagnosis date, and county/city. Conditional logistic regression was used to identify associated characteristics.ResultsDuring 2001–2014, 93 of 6,624 AHC reports were HIV/AHC cases; the annual case count increased from one in 2009 to 34 in 2014. All were males (81 [87%] MSM) aged 21–49 years with AHC diagnosed 2–5,923 days after HIV diagnoses. Sixty-eight (73%) lived in the Taipei metropolitan area. Detected HCV genotypes were 2a (n = 6), 1b (n = 5), 1b + 2a (n = 1) and 2b (n = 1). Among 28 HIV/AHC patients interviewed in 2014, 13 (46%) reported engaging in unprotected sex ≤3 months before AHC diagnosis. Seventy-nine HIV/AHC cases were matched to 158 controls. HIV/AHC was associated with recent syphilis (adjusted odds ratio [aOR], 10.9; 95% confidence interval [CI], 4.2–28.6) and last syphilis >6 months (aOR, 2.9; 95% CI, 1.2–6.9).ConclusionsHIV/AHC cases continued to increase particularly among sexually active HIV-infected MSM with a syphilis diagnosis in northern Taiwan. We recommend surveillance of associated behavioral and virologic characteristics and HCV counseling and testing for HIV-infected men in Taiwan. 相似文献

The examination of all persons suspected in the use narcotics (including suppliers and vendors of drugs) in Svetlogorsk (Belarus) for the presence of antibodies to HIV revealed 811 cases of HIV infection, i.e. 1% of the whole population was found to be infected by HIV. More than 90% of all HIV-infected persons were drug addicts introducing narcotic intravenously; young people aged 18 to 29 years constituted 81% (of these, 76% were males and 24% were females). The rapid spread of HIV was caused by the use of a ready-made HIV-infected drug which had been supplied for sale and could have been infected in the process of manufacture or packing. 相似文献

The aim of this article was to investigate the prevalence of hypertension with selected anthropometric variables in a sample of hospitalized coronary heart disease (CHD) patients in Croatia. This study investigated patients hospitalized in the period of October 1st 2007 until January 7th 2010 because of acute or chronic CHD in various hospitals in Croatia (N = 1,298). Prevalence of hypertension in surveyed patient population was high: 70.1% of participants had raised blood pressure (BP) or previously diagnosed hypertension. Men had statistically significantly higher mean diastolic BP values than women (78.91 +/- 8.97 vs. 77.12 +/- 10.61 mmHg, p = 0.011). Prevalence of hypertension was statistically significantly more frequent in women (80.6% vs. 65.8%, p < 0.001). Hypertension still represents an important problem among hospitalized Croatian CHD patients. Its prevalence, unfortunately, continues to increase in this population, suggesting that there is still great potential for improvement of preventive cardiology standards and measures that have already been undertaken. 相似文献

The work deals with the results of the study of T-lymphocytes and their subpopulations (active, thermostable, theophylline-sensitive and theophylline-resistant) in 102 children with chronic viral hepatitis B, depending on the effectiveness of thymalin therapy. The sensitization of lymphocytes to specific antigens was studied. Among patients with chronic viral hepatitis B and cirrhosis of the liver the homozygous phenotype of haptoglobin is registered essentially more frequently (63.6% and 82.4% respectively) than among healthy persons (44.0%). The patients of this group showed a decrease in the number of T-lymphocytes, disturbances in the suppressor/helper ratio: hypersuppression in persisting hepatitis and hyposuppression in active hepatitis. In 71.6% of cases thymalin therapy produced an effect manifested by clinico-biochemical remission, an increase in the number of T-lymphocytes, thermostable cells and the normalization of the T-suppressor/T-helper ratio. In these patients sensitization to HBsAg essentially decreased (from 30.5% to 13.9%), while sensitization to human liver lipoprotein retained its high level even after treatment with thymalin. 相似文献

The clinical expression of infection with the human immunodeficiency virus (HIV) appears increasingly complex. It includes manifestations due to opportunistic diseases, as well as illness directly caused by HIV itself. Neurologic disease may include involvement of the brain, spinal cord and peripheral nerves and is probably directly caused by HIV, as is lymphocytic interstitial pneumonia. The etiology of the chronic diarrhea and a papular pruritic skin eruption associated with HIV infection is unclear. Between 2% and 8% of HIV-infected persons progress to the acquired immunodeficiency syndrome (AIDS) per year, with no apparent decrease in the rate of disease progression over time. A chronically activated state secondary to chronic microbial antigenic exposure may increase both the susceptibility to HIV infection and development of disease. Increased HIV gene expression, followed by persistent antigenemia, appear to be triggering factors in clinical deterioration. The role, if any, of environmental and/or genetic cofactors remains unclear. 相似文献

Introduction
Streptococcus pneumoniae is the commonest cause of bacteremic pneumonia among HIV-infected persons. As more countries with high HIV prevalence are implementing infant pneumococcal conjugate vaccine (PCV) programs, we aimed to describe the baseline clinical characteristics of adult invasive pneumococcal disease (IPD) in the pre-PCV era in South Africa in order to interpret potential indirect effects following vaccine use.Methods
National, active, laboratory-based surveillance for IPD was conducted in South Africa from 1 January 2003 through 31 December 2008. At 25 enhanced surveillance (ES) hospital sites, clinical data, including HIV serostatus, were collected from IPD patients ≥ 5 years of age. We compared the clinical characteristics of individuals with IPD in those HIV-infected and -uninfected using multivariable analysis. PCV was introduced into the routine South African Expanded Program on Immunization (EPI) in 2009.Results
In South Africa, from 2003–2008, 17 604 cases of IPD occurred amongst persons ≥ 5 years of age, with an average incidence of 7 cases per 100 000 person-years. Against a national HIV-prevalence of 18%, 89% (4190/4734) of IPD patients from ES sites were HIV-infected. IPD incidence in HIV-infected individuals is 43 times higher than in HIV-uninfected persons (52 per 100 000 vs. 1.2 per 100 000), with a peak in the HIV-infected elderly population of 237 per 100 000 persons. Most HIV-infected individuals presented with bacteremia (74%, 3 091/4 190). HIV-uninfected individuals were older; and had more chronic conditions (excluding HIV) than HIV-infected persons (39% (210/544) vs. 19% (790/4190), p<0.001). During the pre-PCV immunization era in South Africa, 71% of serotypes amongst HIV-infected persons were covered by PCV13 vs. 73% amongst HIV-uninfected persons, p = 0.4, OR 0.9 (CI 0.7–1.1).Conclusion
Seventy to eighty-five percent of adult IPD in the pre-PCV era were vaccine serotypes and 93% of cases had recognized risk factors (including HIV-infection) for pneumococcal vaccination. These data describe the epidemiology of IPD amongst HIV-infected and -uninfected adults during the pre-PCV era and provide a robust baseline to calculate the indirect effect of PCV in future studies. 相似文献16.
Serum guanase activity was measured in 20 healthy adults and in 62 patients with acute viral hepatitis, chronic active hepatitis, chronic persistent hepatitis, liver cirrhosis and fatty liver. Guanase and gamma-GT in patients were elevated in 87 and 64%, respectively. Elevated guanase activities were found in most cases of acute viral hepatitis, as well as in chronic hepatopathies. In patients with acute viral hepatitis pathologic activities of guanase were found following partial or total normalization of other liver function tests. 相似文献

39 patients with acute infectious endocarditis were observed; of these, 28 patients had HIV infection at different stages of the disease. The specific features of the course of acute infectious endocarditis in HIV-infected patients were established. The severe course of acute septic endocarditis was observed in those patients whose parameters of the cell-mediated immune system (cells CD4+) were in the state of compensation or subcompensation. At different stages of HIV infection different clinical syndromes of infectious endocarditis prevailed. In patients with HIV infection the combined lesions of the heart valve apparatus were observed and mixed microflora was isolated from the blood more frequently. The development of acute septic endocarditis negatively affected the course of HIV infection and was manifested by a rapid decrease in the amount of CD4 lymphocytes. 相似文献

The results obtained in the study of the characteristic features of the spread of viral hepatitis B under the conditions of family foci are presented. Children with viral hepatitis B have been found to infect 4-5 persons per 1,000 contacts, while adults infect not more than 1 person per 1,000 contacts. The results of the study have led to the conclusion that the idea of the potential danger of hepatitis B patients as the source of infection depends on the forms of the infectious process taken into account in evaluating its epidemiological significance. Latent cases of hepatitis B virus infection appear more frequently among the contacts of sick children than among those of sick adults, but the manifest forms of the disease are more frequently caused by infection contacted from sick adults. 相似文献

Despite the success of antiretroviral therapy (ART), it does not cure Human Immunodeficiency Virus (HIV) and discontinuation results in viral rebound. Follicular dendritic cells (FDC) are in direct contact with CD4+ T cells and they retain intact antigen for prolonged periods. We found that human FDC isolated from patients on ART retain infectious HIV within a non-degradative cycling compartment and transmit infectious virus to uninfected CD4 T cells in vitro. Importantly, treatment of the HIV+ FDC with a soluble complement receptor 2 purges the FDC of HIV virions and prevents viral transmission in vitro. Our results provide an explanation for how FDC can retain infectious HIV for extended periods and suggest a therapeutic strategy to achieve cure in HIV-infected humans. 相似文献

BackgroundDespite an increasing number of studies exploring prevalence of depression among hypertensive patients in high income countries, limited data is available from low and middle income countries, particularly Nepal. Our aim was to investigate the prevalence of undiagnosed (sub clinical) depression and associated risk factors among hypertensive patients attending a tertiary health care clinic in Nepal.MethodsThe study was based on a cross-sectional study design, with 321 hypertensive patients attending the Out-Patient Department of a central hospital in Nepal. Blood measure was recorded via a mercury column sphygmomanometer. Depression levels were assessed using the Beck Depression Inventory-Ia (BDI) scale. Demographics and risk factors were assessed.ResultThe proportion of participants with undiagnosed depression was 15%. Multivariable analyses demonstrated an increase in BDI scores with increased aging. Approximately a 1 point increase in the BDI score was observed for each additional decade of aging in hypertensive patients. Additional factors associated with increased risk of depression included being female (4.28 point BDI score increase), smoking (5.61 point BDI score increase), being hypertensive with no hypertensive medication (4.46 point BDI score increase) and being illiterate (4.46 point BDI score increase).ConclusionsAmong persons with hypertension in outpatient settings in Nepal, demographic (age, sex, education), behavioural (smoking,) and adherence factors (anti-hypertensive medication) were associated with undiagnosed depression. Screening programs in Nepal may assist early intervention in hypertensive patients with sub clinical depression. 相似文献
