Ferreira, Maria Angelica; Gazzana, Marcelo Basso; Barreto, Sergio Saldanha Menna; Knorst, Marli Maria

2001-01-01

Hepatopulmonary syndrome is characterized by a triad consisting of liver disorder, pulmonary vascular dilatation, and hypoxaemia. No case of hepatopulmonary syndrome associated with AIDS has been reported so far. In this study, the authors report the case of a 43-year woman with AIDS and virus C cirrhosis taking prophylactic cotrimoxazole for pneumocystosis and retroviral therapy. Upon admission, the patient presented dyspnoea, cyanosis, digital clubbing, vascular spiders, and normal chest examination. Chest X-ray revealed bilateral interstitial infiltration and evidenced increased alveolar-arterial gradient and liver function impairment. Intrapulmonary shunt was evidenced by contrast-enhanced echocardiography and radionuclide perfusion scanning, thus confirming hepatopulmonary syndrome. (author)

The paper reviews data on drug use in relation to the spread of human immunodeficiency virus and AIDS in South America and the Caribbean. Information was gathered by thoroughly reviewing major bibliographic databanks, web sites of international institutions and regional networks working with substance misuse or human immunodeficiency virus and AIDS, and abstracts from conferences and meetings. Although some gaps remain, a growing body of evidence documents the significant role of injected cocaine in the Brazilian and Southern Cone epidemics. The Caribbean and the Andean areas have thus far been spared in large part from the spread of injection drug use and its consequences, but the situation has been changing in Southern Cone countries towards a higher prevalence of harmful injection habits. Additional challenges have been posed by the increasing availability of heroin in the Andean Area and the abuse of crack cocaine and its impact on the sexual transmission of human immunodeficiency virus in many cities. Harm reduction strategies have been established in most areas of Brazil and are gaining momentum in Argentina. Other countries in the Region still face serious limitations due to restrictive legislation and lack of broader support. Greater participation of Latin American and Caribbean countries in research protocols and continued debate on both successful and failed experiences should be encouraged in order to minimize existing barriers to the full adoption of effective measures to curb the human immunodeficiency virus and AIDS epidemic in this Region.

Use of etanercept in human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) patients.

Ting, Patricia T; Koo, John Y

Etanercept (Enbrel, Amgen, Thousand Oaks, CA), a soluble p75 tumor necrosis factor receptor:FC (TNFR:FC) fusion protein for plasma cytokines, specifically tumor necrosis factor-alpha (TNF-alpha), is used in the treatment of immune-mediated rheumatic diseases. To our knowledge, the use of etanercept in patients with human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) is relatively uncommon. The main purpose of this short review is to examine the safety of etanercept in patients with HIV/AIDS. A Medline search was conducted using the keywords etanercept and HIV and/or AIDS for any published articles between 1966 to the present (September 2004). A case report, one case series, and one clinical trial pertained to the use of etanercept in HIV patients. No reports were found on the use of etanercept in AIDS. In addition, two case reports were found documenting the use of infliximab in HIV patients. Preliminary reports indicate that the administration of etanercept does not appear to increase the morbidity or mortality rates in HIV. The inhibition of TNF-alpha may actually improve the symptoms of HIV/AIDS-associated aphthous ulcers, cachexia, dementia, fatigue, and fever, as well as help manage concomitant rheumatic diseases and psoriasis. The use of etanercept shows promise for applications in disease management in patients with HIV/AIDS. Continued research efforts are necessary to establish the long-term safety and efficacy of etanercept and other biologic agents in this patient population.

An international colloquium on AIDS held near Paris from October 26-28, 1989, unlike the World Conference on AIDS in Montreal the year before, was able to find reasons for optimism. Significant progress was reported in immunotherapy and in chemotherapy. Successful experiments in vaccinating monkeys against the AIDS virus were reported from the US, France, and Zaire. Time is needed to prove the efficacy of the vaccines because of the slow development in AIDS. A vaccine is being tested by Jonas Salk and collaborators in 75 seropositive volunteers who do not yet show full blown disease but who have very low levels of T4 lymphocytes. Plans are underway for a larger test on 500 seropositive patients at different stages of infection. According to Salk, the new chemical and logical approach toward AIDS will allow combinations of immunotherapy and chemotherapy to destroy the virus. R. Gallo of France listed as accomplishments of the past year a better understanding of the virus, improved case management techniques, increased ability to control Kaposi's sarcoma, considerable progress in the search for a vaccine, and detection of immune proteins that affect the virus. New biological markers permit establishment of correlations between cellular modifications and the progress of the disease as well as the precise effects of treatment. The new immune system drugs immuthiol and DDI are expected to reach the market soon. Patients very soon will be able to receive less toxic alternative treatments, which can be combined for greater efficacy once their toxic interactions are understood.

Full Text Available Abstract Background Studies have shown that the immunosuppression induced by the human immunodeficiency virus (HIV accelerates the natural history of liver disease associated with hepatitis C virus (HCV, with 3- to 5-fold higher odds of coinfected individuals developing cirrhosis. However, estimates of the seroprevalence of hepatitis C among people living with HIV/acquired immune deficiency syndrome (AIDS (PLHA in Latin America and the Caribbean (LAC are widely variable. Methods We performed a systematic review to estimate the seroprevalence of HCV among PLHA. We searched studies on HIV and HCV infections in LAC included in the PubMed, LILACS and Embase databases in December of 2014 with no time or language restrictions. The following combinations of search terms were used in the PubMed and Embase databases: (HIV OR Acquired Immunodeficiency Syndrome Virus OR AIDS OR HTLV OR Human Immunodeficiency Virus OR Human T Cell AND (HCV OR HEPATITIS C OR HEPATITIS C VIRUS OR HEPACIVIRUS AND (name of an individual country or territory in LAC. The following search terms were used in the LILACS database: (HIV OR AIDS OR Virus da Imunodeficiencia Humana AND (HCV OR Hepatite C OR Hepacivirus. An additional 11 studies were identified through manual searches. A total of 2,380 publications were located, including 617 duplicates; the remaining articles were reviewed to select studies for inclusion in this study. Results A total of 37 studies were selected for systematic review, including 23 from Brazil, 5 from Argentina, 3 from Cuba, 1 from Puerto Rico, 1 from Chile, 1 from Colombia, 1 from Mexico, 1 from Peru and 1 from Venezuela. The estimated seroprevalence of HCV infection varied from 0.8 to 58.5 % (mean 17.37; median 10.91, with the highest in Argentina and Brazil and the lowest in Venezuela and Colombia. Conclusions Investigation of HCV infection among PLHA and of HIV infection among people living with HCV is highly recommended because it allows for better

A novel role for APOBEC3: Susceptibility to sexual transmission of murine acquired immunodeficiency virus (mAIDS) is aggravated in APOBEC3 deficient mice

Science.gov (United States)

2012-01-01

Background APOBEC3 proteins are host factors that restrict infection by retroviruses like HIV, MMTV, and MLV and are variably expressed in hematopoietic and non-hematopoietic cells, such as macrophages, lymphocytes, dendritic, and epithelia cells. Previously, we showed that APOBEC3 expressed in mammary epithelia cells function to limit milk-borne transmission of the beta-retrovirus, mouse mammary tumor virus. In this present study, we used APOBEC3 knockout mice and their wild type counterpart to query the role of APOBEC3 in sexual transmission of LP-BM5 MLV – the etiological agent of murine AIDs (mAIDs). Results We show that mouse APOBEC3 is expressed in murine genital tract tissues and gametes and that genital tract tissue of APOBEC3-deficient mice are more susceptible to infection by LP-BM5 virus. APOBEC3 expressed in genital tract tissues most likely plays a role in decreasing virus transmission via the sexual route, since mice deficient in APOBEC3 gene have higher genitalia and seminal plasma virus load and sexually transmit the virus more efficiently to their partners compared to APOBEC3+ mice. Moreover, we show that female mice sexually infected with LP-BM5 virus transmit the virus to their off-spring in APOBEC3-dependent manner. Conclusion Our data indicate that genital tissue intrinsic APOBEC3 restricts genital tract infection and limits sexual transmission of LP-BM5 virus. PMID:22691411

The Sun article, "Employers finding that AIDS in the workplace is a managerial nightmare" (April 3), did not accurately portray the status of AIDS in the workplace. The AIDS virus, HTLV III, is transmitted by body fluids, primarily semen and blood, and there is no known risk of transmitting the virus by casual contact in the workplace. The Center for Disease Control (CDC) released guidelines for child care workers last August. Guidelines on preventing transmission of AIDS in the workplace were issued by CDC in November 1985. These guidelines specifically discussed health care, personal service, and food service workers. The recommendations were against routine screening. Furthermore, employment should not be restricted on the basis of a positive HTLV III antibody test. A person with HTLV III infection should be exempt from the workplace only if there are circumstances interfering with job performance. In Maryland, the Governor's Task Force on AIDS has gone on record as endorsing CDC guidelines related to employment. Furthermore, the task force condemns discrimination based on the disease AIDS, AIDS Related Complex (ARC), or HTLV III infection. Increasingly AIDS patients are being considered legally disabled and therefore are protected by federal and state laws prohibiting discrimination on the basis of a handicap. Marylanders who are subjected to mandatory HTLV III screening in the workplace, or if discriminated against on the basis of HTLV III inefction, should contact the Maryland Commission on Human Relations, the Maryland Department of Health and Mental Hygiene, or the Health Education Resource Organization (HERO). All 3 of these resources guarantee confidentiality. It is only by employees reporting incidents that a nightmare in the workplace can be avoided in Maryland. full text

Full Text Available HIV infection and AIDS is increasingly becoming a major public health problem in our country. Currently, the reported cases represent only the 'tip of the iceberg' of the problem. In view of the fact that no cure or vaccine for the disease has yet been found, spreading knowledge and removing misconceptions is about the only way that AIDS can be effectively tackled.This handbook, developed by Prof. Shankar Chowdhury and associates, seeks to address all levels of medical and non-medical AIDS workers, as well as the layman. It deals with topics ranging from biology of the virus, symptoms and transmission of disease, to prevention, counselling for infected persons and action plan for AIDS education.The biology of the virus and the immune system is described in simple terms, as well as methods of testing for HIV, and what these test results mean. The progression of disease in adults and children, development of symptoms, diagnostic criteria for AIDS, treatment and outcome of disease is dealt with. How AIDS spreads between people, and the health risk for health workers and families is examined. The various ways in which transmission of HIV can be prevented is looked at in detail, including public health measures, national and internatonal action, and ethical and human rights issues involved.

1985-05-01

Human T-cell lymphotropic viruses designated HTLV III or LAV are considered to represent the causative agents of the acquired immunodeficiency syndrome (AIDS). Therefore a simple direct RIA or ELISA method for antibodies to distinct epitopes of HTLV III/LAV structural components would be of great value. The authors describe RIA and ELISA assays which obviate the need for purified virus or virus proteins, do not utilize infected cells and thus do not diminish the source for continuous production of viral antigens and are specific for a major core protein of HTLV III/LAV.

Computer-Aided Design of an Epitope-Based Vaccine against Epstein-Barr Virus

Directory of Open Access Journals (Sweden)

Julio Alonso-Padilla

2017-01-01

Full Text Available Epstein-Barr virus is a very common human virus that infects 90% of human adults. EBV replicates in epithelial and B cells and causes infectious mononucleosis. EBV infection is also linked to various cancers, including Burkitt’s lymphoma and nasopharyngeal carcinomas, and autoimmune diseases such as multiple sclerosis. Currently, there are no effective drugs or vaccines to treat or prevent EBV infection. Herein, we applied a computer-aided strategy to design a prophylactic epitope vaccine ensemble from experimentally defined T and B cell epitopes. Such strategy relies on identifying conserved epitopes in conjunction with predictions of HLA presentation for T cell epitope selection and calculations of accessibility and flexibility for B cell epitope selection. The T cell component includes 14 CD8 T cell epitopes from early antigens and 4 CD4 T cell epitopes, targeted during the course of a natural infection and providing a population protection coverage of over 95% and 81.8%, respectively. The B cell component consists of 3 experimentally defined B cell epitopes from gp350 plus 4 predicted B cell epitopes from other EBV envelope glycoproteins, all mapping in flexible and solvent accessible regions. We discuss the rationale for the formulation and possible deployment of this epitope vaccine ensemble.

Mononuclear cells were obtained from 71 human immunodeficiency virus type 1 (HIV-1) seropositive subjects presenting and first visit either as asymptomatic or with minor symptoms and with CD4 lymphocytes greater than 550 per mm3 (group A, 35 patients) or as patients with AIDS, AIDS-related illnesses, or CD4 lymphocytes less than 400 per mm3 (group B, 36 patients). After 1-5 years of follow-up, 13 patients of group A had essentially retained their initial status (asymptomatics); the 22 others had suffered clinical or immunological deterioration (progressors). Frozen cells were thawed and submitted to lethal gamma-irradiation in vitro (4500 rads; 1 rad = 0.01 Gy) before they were cultured with normal phytohemagglutinin-stimulated lymphocytes to determine radiation-resistant HIV expression ex vivo (R-HEV). HIV antigenemia correlated with R-HEV values in 142 samples (r = 0.92, P less than 0.001) but was a less sensitive predictor of disease than R-HEV. R-HEV was detected in all specimens from patients with major AIDS-related illnesses or HIV-associated CD4 lymphopenia. In 77% of the progressors from group A, R-HEV detection preceded the onset of AIDS-associated disease or CD4 lymphopenia by 1 year (average). Conversely, R-HEV was low or was not detected in 36 sequential specimens from the 13 patients who remained asymptomatic over the following 2-5 years. Thus, persistently low HIV expression in vivo predicted a nondiseased state, whereas higher HIV expression levels seemed necessary for disease to occur. These data indicate that R-HEV is related to productive HIV infection in vivo, the latter acting as a determinant of AIDS-related illnesses. In view of this, measurement of HIV expression levels in the patient should be useful in antiviral efficacy trials

AIDS and its effects on the advancement of women.

Science.gov (United States)

1989-01-01

This document gives an overview of the worldwide spread of acquired immune deficiency syndrome (AIDS), the means of its prevention, and its effects on women who are not infected. It also explains how the AIDS virus is not spread, and why it is important not to be afraid of those infected with the AIDS virus. It stresses the need for information at a time when a vaccine or cure are not yet available, and education is the only means of prevention. The global mobilization being conducted to fight the AIDS crisis is discussed. Different ways in which women are at risk to infection by the HIV virus are reviewed, especially the subordination of women. This denies them the same education, legal rights, training, health, and independent incomes, all of which reduces their chance for access to information about AIDS. It considers risk of being infected by a partner, from a blood transfusion, increased susceptibility in someone who already has a sexually transmitted disease, increased susceptibility in a woman who has been circumcised, risk of infection from rape, and how women are coerced into prostitution, putting them at risk for AIDS. It also covers HIV infection and contraception, the danger to professional health-care workers, transmission of HIV infection from mother-to-infant, and discrimination that is AIDS-related. Women who are not infected are impacted by AIDS because they suffer stress as caretakers. The document also discusses the social and economic consequences of AIDS.

Acute meningoencephalomyelitis due to varicella-zoster virus in an AIDS patient: report of a case and review of the literature

Marcelo Corti

2011-12-01

Full Text Available Varicella-zoster virus (VZV meningoencephalomyelitis is a rare but severe neurological complication of VZV reactivation in immunocompromised patients. We report the case of an HIV-infected individual who developed an acute and severe meningoencephalomyelitis accompanied by a disseminated cutaneous eruption due to VZV. The presence of VZV DNA in cerebrospinal fluid was confirmed by polymerase chain reaction (PCR technique. The patient started undergoing an intravenous acyclovir therapy with a mild recovery of neurological manifestations. Varicella-zoster virus should be included as a cause of acute meningoencephalomyelitis in patients with AIDS. Early diagnosis followed by specific therapy should modify the rapid and fulminant course for this kind of patients.

Comparative virology and AIDS (review).

Kodama, M; Kodama, T

1996-03-01

The scientific debate between pros and cons of the HIV criminal theory of AIDS still remains unsettled. The purpose of this review is to promote resolution of the problem by extracting a common principle of the host-virus relation using data resources for each of 4 viruses as follows: a) polyoma virus, b) Marek's disease virus, c) Ebola virus, d) Korean hemorrhagic fever virus. Conclusions drawn from this study are given as follows: i) Environment emerged as the cardinal factor to modify the process of virus infection in all of the 4 viruses studied. Above all, an accelerating effect of environmental stress on the progression of virus infection was noted in vivo in the majority of viral diseases. ii) Evidence is available to indicate that a healthy cell (or a healthy individual) may harbor virus genes of multiple species without manifesting any pathologic sign. iii) Evidence also suggests that the biological property as well as morphological structure of a virus may vary in reponse to a change of the bioenvironment. On the basis of the above information, we propose to renounce 2 assumptions of classical infection model: a) the hereditarily determined virulence of a microorganism (including virus) be the sole determinant of infection to the effect that its invasion into the host should automatically complete the programmed course of infection; b) virus, a quasi-living creature, should reserve its behavioral independence irrespective of a change of the bioenvironment. The new infection model was constructed on the basis of the selfish gene concept that had been invented by Richard Dawkins to explain the altruistic behavior of an individual. That is, the fate of an exogenous or endogenous virus is under the dual control of the host genome (selfish gene) and the outer environment. The progression of virus infection is conditioned by a crosstalk between them. The selfish gene may use virus (a lifeless substance) as a magic bullet to induce a designated host response. In

Full Text Available Human immunodeficiency virus (HIV/AIDS is a manageable infectious disease by the effectiveness of highly active antiretroviral therapy. AIDS-related stigma and conflict may create distress and deteriorate quality of life (QoL of people living with HIV/AIDS (PLWHA. This cross-sectional, descriptive, correlational study using structural questionnaires aimed to explore the stress, needs, QoL, and associated factors of PLWHA in Taiwan. A total of 200 PLWHA participating in this study needed most on treatment of HIV and prevention of AIDS, and health maintenance. They had worse QoL in physical, psychological, and social domains (all p < 0.001 than the general population. Stress was the most significant predictor (β = −0.25 to −0.54, p < 0.01 for all four domains of QoL. Needs was not significantly associated with QoL. The QoL of PLWHA can be explained by demographics, self-perception on health, needs, and stress for 25.3–40.7% of variances. No association existed between CD4+ counts and QoL in Taiwanese PLWHA. It is important to recognize the perception of PLWHA on their health status, which is significantly associated with their QoL, besides monitoring their physical indicators of health (CD4+ counts. To recognize the stress and needs that PLWHA experience and to develop intervention programs targeting strategies on HIV disclosure, prevention and health maintenance are crucial for PLWHA's QoL.

South Africa is known to have one of the highest prevalence rates of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) globally, with one in seven healthcare workers being HIV-positive. An HIV-positive healthcare workforce is less equipped to respond to the increasing spread of the epidemic. Assessment of the factors contributing to high HIV prevalence rates among healthcare workers is important in planning the development of human resources. This review sought to identify and understand predominant risky sexual behaviours among healthcare workers in HIV and AIDS-affected countries. This study reviewed articles focusing on sexual behaviour among healthcare workers. Major health science databases (e.g. ProQuest, Cochrane, PubMed and CINAHL) were searched for combinations of keywords including 'healthcare workers', 'risky sexual behaviour' and 'HIV and AIDS'. Articles from a range of countries met inclusion and exclusion criteria. Findings of the study revealed three main contributing factors: unprotected sex, multiple sex partners and sexual violence. Sexual violence emerged as the dominant risk factor in the majority of the studies. Most research was conducted in developed countries where the HIV infection rate is much lower than it is in developing countries. More research needs to be conducted in developing countries and appropriate strategies should be implemented to reduce sexual violence among healthcare workers. Appropriate procedures on reporting sexual violence coupled with education on HIV and AIDS as well as influencing attitudes and belief systems could assist in reducing the spread of HIV and AIDS within the healthcare workforce while minimising the effect on patient care.

HIV/AIDS has become a chronic disease since anti-retroviral therapy has reduced the related rates of morbidity and mortality and maintained the immunity of people living with the human immunodeficiency virus / AIDS (PLWHA). PLWHA have psychological needs and many hope to improve their quality of life (QoL) over the long course of their treatment. Despite the large number of AIDS cases, there are limited reports addressing the issue of QoL among PLWHA in China. The present study aims to explore the stress, needs, QoL, and related factors among PLWHA in China. This cross-sectional, descriptive study used a structural questionnaire to assess the stress, needs, and QoL of 100 PLWHA in Shenyang, China. The most stressful issues faced by the participants were admitting HIV/AIDS status publicly and explaining their illness to others. Their needs were mainly related to receiving adequate information about HIV-related medical services, examination, and treatment and learning how to prevent disease progression. Among the four domains of QoL, the score in the physical domain was the lowest. The stress, needs, and QoL of the participants were significantly inter-correlated. However, only stress was found to predict QoL (β = -.25 to -.60, p stress, meet the needs, and improve the QoL of PLWHA, healthcare providers should work to lower the risk of divulgence, provide adequate healthcare information, and work to reduce the stigma and discrimination that is associated with having HIV/AIDS.

Bone Marrow Gene Therapy for HIV/AIDS

Directory of Open Access Journals (Sweden)

Elena Herrera-Carrillo

2015-07-01

Full Text Available Bone marrow gene therapy remains an attractive option for treating chronic immunological diseases, including acquired immunodeficiency syndrome (AIDS caused by human immunodeficiency virus (HIV. This technology combines the differentiation and expansion capacity of hematopoietic stem cells (HSCs with long-term expression of therapeutic transgenes using integrating vectors. In this review we summarize the potential of bone marrow gene therapy for the treatment of HIV/AIDS. A broad range of antiviral strategies are discussed, with a particular focus on RNA-based therapies. The idea is to develop a durable gene therapy that lasts the life span of the infected individual, thus contrasting with daily drug regimens to suppress the virus. Different approaches have been proposed to target either the virus or cellular genes encoding co-factors that support virus replication. Some of these therapies have been tested in clinical trials, providing proof of principle that gene therapy is a safe option for treating HIV/AIDS. In this review several topics are discussed, ranging from the selection of the antiviral molecule and the viral target to the optimal vector system for gene delivery and the setup of appropriate preclinical test systems. The molecular mechanisms used to formulate a cure for HIV infection are described, including the latest antiviral strategies and their therapeutic applications. Finally, a potent combination of anti-HIV genes based on our own research program is described.

Psychiatric interventions for AIDS-spectrum disorders.

Perry, S W; Markowitz, J

1986-10-01

Although the medical and psychosocial problems posed by acquired immune deficiency syndrome (AIDS) are unique, interventions to treat AIDS-related psychiatric disorders are currently available. The depression, delirium, and denial that occur in medically hospitalized patients with AIDS respond to standard psychotherapeutic and psychopharmacological approaches. Outpatients with AIDS or AIDS-related complex benefit from clarification, abreaction, and support if the therapist accepts the regression associated with the sick role, focuses initially on somatic rather than on psychological concerns, and overcomes unwarranted fears of contagion. Patients with AIDS-related dementia are helped considerably by early diagnosis and planning, and patients with antibodies to the AIDS virus require a psycho-educational approach that includes stress inoculation and problem-solving techniques. The authors describe the above interventions as well as common countertransference responses that impede their implementation.

Virus-host interaction in feline immunodeficiency virus (FIV) infection.

Science.gov (United States)

Taniwaki, Sueli Akemi; Figueiredo, Andreza Soriano; Araujo, João Pessoa

2013-12-01

Feline immunodeficiency virus (FIV) infection has been the focus of several studies because this virus exhibits genetic and pathogenic characteristics that are similar to those of the human immunodeficiency virus (HIV). FIV causes acquired immunodeficiency syndrome (AIDS) in cats, nevertheless, a large fraction of infected cats remain asymptomatic throughout life despite of persistent chronic infection. This slow disease progression may be due to the presence of factors that are involved in the natural resistance to infection and the immune response that is mounted by the animals, as well as due to the adaptation of the virus to the host. Therefore, the study of virus-host interaction is essential to the understanding of the different patterns of disease course and the virus persistence in the host, and to help with the development of effective vaccines and perhaps the cure of FIV and HIV infections.

AIDS and adolescents: why should we be concerned?

Science.gov (United States)

1987-11-01

AIDS most often strikes people aged 20-40 years old. However, due to the long period of incubation from initial infection with HIV to the development of AIDS, many young adults with AIDS may have been infected with the virus while they were teenagers. Many adolescents could be unsuspecting carriers of the virus. It is normal for developing adolescents to experiment with their bodies and those of their peers. Inherent to this experimentation and growth is risk taking with sex and drugs. Sexual intercourse without condom use and IV drug use with non-sterile injecting equipment are risk factors for contracting and transmitting HIV. Without creating undue fear, teenagers must be taught how AIDS is spread, how it is not spread, and how they can protect themselves from HIV. They need to understand that certain behaviors are risky, not belonging to a certain population subgroup. This article describes efforts underway in Finland, Mexico, Chile, the US, and Thailand to teach adolescents about AIDS. At the start of Finland's AIDS education campaign in early January 1987, the use of a condom was demonstrated on national television news. The country's National Board of Health also distributed a booklet on AIDS and a sample condom to all 16-21 year olds in Finland. Teens themselves can also be effective AIDS educators. Efforts to teach adolescents about HIV/AIDS and promote behavior change should be the product of comprehensive community involvement.

A thorough understanding of the role of human immunodeficiency virus (HIV) intrahost evolution in AIDS pathogenesis has been limited by the need for longitudinally sampled viral sequences from the vast target space within the host, which are often difficult to obtain from human subjects. CD8 + lymphocyte-depleted macaques infected with simian immunodeficiency virus (SIV) provide an increasingly utilized model of pathogenesis due to clinical manifestations similar to those for HIV-1 infection and AIDS progression, as well as a characteristic rapid disease onset. Comparison of this model with SIV-infected non-CD8 + lymphocyte-depleted macaques also provides a unique opportunity to investigate the role of CD8 + cells in viral evolution and population dynamics throughout the duration of infection. Using several different phylogenetic methods, we analyzed viral gp120 sequences obtained from extensive longitudinal sampling of multiple tissues and enriched leukocyte populations from SIVmac251-infected macaques with or without CD8 + lymphocyte depletion. SIV evolutionary and selection patterns in non-CD8 + lymphocyte-depleted animals were characterized by sequential population turnover and continual viral adaptation, a scenario readily comparable to intrahost evolutionary patterns during human HIV infection in the absence of antiretroviral therapy. Alternatively, animals that were depleted of CD8 + lymphocytes exhibited greater variation in population dynamics among tissues and cell populations over the course of infection. Our findings highlight the major role for CD8 + lymphocytes in prolonging disease progression through continual control of SIV subpopulations from various anatomical compartments and the potential for greater independent viral evolutionary behavior among these compartments in response to immune modulation. IMPORTANCE Although developments in combined antiretroviral therapy (cART) strategies have successfully prolonged the time to AIDS onset in HIV-1

2017-01-01

Cancer is a significant cause of morbidity and mortality in people infected with the human immunodeficiency virus (HIV). In fact, 30–40% of people with this condition will develop a malignancy during their lifetime. The majority of cancers affecting HIV positive people are those established as AIDS defining: Kaposi’s sarcoma (KS), non-Hodgkin’s lymphoma (NHL) and invasive cervical cancer. However, other types of cancer also appear to be more common among those infected with HIV. While not classified as AIDS defining, these malignancies are affecting the HIV/AIDS community greatly and have been referred to as ‘AIDS-associated malignancies’ or ‘opportunistic’ cancers. Two analyses have revealed a two to three fold increase in the overall risk of developing these cancers. The introduction of highly active antiretroviral therapy (HAART) has resulted in decreased mortality and morbidity, and the majority of people in developed countries infected with HIV are living with only mild to moderate immunosuppression because of wide access to antiretroviral therapy. HIV positive persons have a markedly elevated risk for two malignancies: KS and NHL, which are themselves considered sufficient to signify progression to AIDS. KS and NHL are caused by a loss of immune control of latent infection with oncogenic viruses (human herpes virus 8 (HHV-8) for KS, Epstein–Barr virus for certain NHL subtypes). Other cancers caused by viruses (e.g. cervical and anal canal cancers caused by human papillomavirus (HPV), liver cancer caused by hepatitis B and C) also occur with increased frequency in this population, although for them, the importance of immune suppression is less clear.

Risky sexual behaviour and human immunodeficiency virus (HIV and acquired immune deficiency syndrome (AIDS among healthcare workers

Directory of Open Access Journals (Sweden)

Natasha Khamisa

2018-01-01

Full Text Available Background: South Africa is known to have one of the highest prevalence rates of human immunodeficiency virus (HIV and acquired immune deficiency syndrome (AIDS globally, with one in seven healthcare workers being HIV-positive. An HIV-positive healthcare workforce is less equipped to respond to the increasing spread of the epidemic. Objectives: Assessment of the factors contributing to high HIV prevalence rates among healthcare workers is important in planning the development of human resources. This review sought to identify and understand predominant risky sexual behaviours among healthcare workers in HIV and AIDS-affected countries. Methods: This study reviewed articles focusing on sexual behaviour among healthcare workers. Major health science databases (e.g. ProQuest, Cochrane, PubMed and CINAHL were searched for combinations of keywords including ‘healthcare workers’, ‘risky sexual behaviour’ and ‘HIV and AIDS’. Articles from a range of countries met inclusion and exclusion criteria. Results: Findings of the study revealed three main contributing factors: unprotected sex, multiple sex partners and sexual violence. Sexual violence emerged as the dominant risk factor in the majority of the studies. Most research was conducted in developed countries where the HIV infection rate is much lower than it is in developing countries. Conclusion: More research needs to be conducted in developing countries and appropriate strategies should be implemented to reduce sexual violence among healthcare workers. Appropriate procedures on reporting sexual violence coupled with education on HIV and AIDS as well as influencing attitudes and belief systems could assist in reducing the spread of HIV and AIDS within the healthcare workforce while minimising the effect on patient care.

Epidemiology of AIDS in Africa--part 2.

Cigielski, J P

1988-03-01

A recently completed study involving over 10,000 people from 6 Central African countries found seroprevalence rates generally under 1% for the acquired immunodeficiency syndrome (AIDS); however, rates were significantly higher for urban residents, prostitutes and their sexual contacts, and patients attending sexually transmitted disease clinics. The 4 major modes of transmission of AIDS in Africa are sexual contact, perinatal transmission, transfusion of infected blood or blood products, and the reuse of equipment such as needles and syringes. In 1985, a 2nd AIDS virus, human immunodeficiency virus (HIV)-2, was discovered in West Africa--a finding with important implications for epidemiologic surveillance, screening programs, and clinical diagnostic testing. Although 45 of the 50 African countries have developed concrete public health policies and strategies for the prevention and control of AIDS, most nations of sub-Saharan Africa lack the economic and social resources to implement these programs effectively. Thus, international cooperation and a commitment on the part of the US and Western Europe to provide assistance will be essential. Needs must be addressed on 2 fronts: treatment of those already infected or suffering from the disease and containment of the AIDS epidemic. Public health efforts should focus initially on high risk behaviors through health education. At the same time, it should be recognized that AIDS is not the largest health issue facing Africans, and there is a complex interaction between AIDS and other health problems such as malnutrition, genital ulcers, diarrhea, and tuberculosis. An approach to AIDS requires an expansion of public health initiatives in areas such as clean water supplies, maternal-child health programs, nutrition and immunization programs, and sexually transmitted disease clinics.

1986-01-01

A cell culture system was developed for the continuous and efficient production of acquired immune deficiency syndrome (AIDS) retrovirus. After infection of a human T-cell line Molt-4 with HTLV-III and LAV the cells grow permanently and produce large amounts of virus continuously. The yields of production of virus were assessed either with reverse transcriptase activity or a newly established biological quantitation assay of active virus. The amounts of virus with this cell system were much higher than those of the H9 cell system. This procedure enabled us first to compare the two viral isolates HTLV-III and LAV directly in the same cell lines. Establishment of the culture system, allowing efficient production of AIDS retroviruses, provides a useful tool for the isolation of the virus from patients with AIDS and for more basic research, such as the mechanisms of immune destruction caused by the virus leading to the occurence of various malignancies (author)

2009-01-01

After the diagnosis of the AIDS symptoms, in 1981, and after the discovery of the virus that causes AIDS, in 1983, the virologists have formulated different theories about its origin. Some of them involved natural causes, e.g., HIV origin from SIV strains. Other theories go further to the possibility of a deadly man-made virus escaped from laboratories or voluntary spread by some conspirative organisations. At this moment, the scientists limits themselves to search proofs to sustain the zoonotic origin of HIV from SIV and its accomodation to human body conditions.

Dermatology and HIV/AIDS in Africa

2011-01-01

Full Text Available Human immunodeficiency virus and the acquired immunodeficiency syndrome (HIV/AIDS have greatly complicated dermatologic disease and the required care in most regions of Africa. Opportunistic infections, ectoparasites, Kaposi sarcoma, and skin manifestations of systemic infections are exceedingly common in patients with HIV/AIDS. Dermatologists have contributed significantly to our knowledge base about HIV/AIDS and have played an important educational role regarding the clinical manifestations historically. Because of the increased burden of skin disease in Africa due to the HIV/AIDS epidemic we must redouble our efforts to provide dermatology education to care providers in Africa. We review the burden of skin disease in Africa, how it relates to HIV/AIDS and global infectious disease, current educational strategies in Africa to address this need, and suggest potential solutions to move these efforts forward.

Human immunodeficiency virus-associated disruption of mucosal barriers and its role in HIV transmission and pathogenesis of HIV/AIDS disease

Tugizov, Sharof

2016-01-01

Abstract Oral, intestinal and genital mucosal epithelia have a barrier function to prevent paracellular penetration by viral, bacterial and other pathogens, including human immunodeficiency virus (HIV). HIV can overcome these barriers by disrupting the tight and adherens junctions of mucosal epithelia. HIV-associated disruption of epithelial junctions may also facilitate paracellular penetration and dissemination of other viral pathogens. This review focuses on possible molecular mechanisms of HIV-associated disruption of mucosal epithelial junctions and its role in HIV transmission and pathogenesis of HIV and acquired immune deficiency syndrome (AIDS).

1988-01-01

Without a medical miracle, it seems inevitable that the Acquired Immune Deficiency Syndrome (AIDS) pandemic will become not only the most serious public health problem of this generation but a dominating issue in 3rd world development. As a present-day killer, AIDS in developing countries is insignificant compared to malaria, tuberculosis, or infant diarrhea, but this number is misleading in 3 ways. First, it fails to reflect the per capita rate of AIDS cases. On this basis, Bermuda, French Guyana, and the Bahamas have much higher rates than the US. Second, there is extensive underreporting of AIDS cases in most developing nations. Finally, the number of AIDS cases indicates where the epidemic was 5-7 years ago, when these people became infected. Any such projections of the growth of 3rd world AIDS epidemics are at this time based on epidemiologic data from the industrialized rations of the north and on the assumption that the virus acts similarly in the south as it does in the US and Europe. Yet, 3rd world conditions differ. Sexually transmitted diseases usually are more prevalent, and people have a different burden of other diseases and of other stresses to the immune system. In Africa, AIDS already is heavily affecting the mainstream population in some nations. Some regions will approach net population declines over the next decade. How far their populations eventually could decline because of AIDS is unclear and will depend crucially on countermeasures taken or not taken over the next 1-2 years. In purely economic terms, AIDS will affect the direct costs of health care, expenses which are unrealistic for most 3rd world countries. Further, the vast majority of deaths from AIDS in developing countries will occur among those in the sexually active age groups -- the wage earners and food producers. Deaths in this age group also will reduce the labor available for farming and industry. AIDS epidemics also may have significant effects on foreign investment in the 3rd

2015-04-03

In late October 2014, Ebola virus disease (Ebola) was diagnosed in a humanitarian aid worker who recently returned from West Africa to New York City (NYC). The NYC Department of Health and Mental Hygiene (DOHMH) actively monitored three close contacts of the patient and 114 health care personnel. No secondary cases of Ebola were detected. In collaboration with local and state partners, DOHMH had developed protocols to respond to such an event beginning in July 2014. These protocols included safely transporting a person at the first report of symptoms to a local hospital prepared to treat a patient with Ebola, laboratory testing for Ebola, and monitoring of contacts. In response to this single case of Ebola, initial health care worker active monitoring protocols needed modification to improve clarity about what types of exposure should be monitored. The response costs were high in both human resources and money: DOHMH alone spent $4.3 million. However, preparedness activities that include planning and practice in effectively monitoring the health of workers involved in Ebola patient care can help prevent transmission of Ebola.

1988-01-01

The CT scans of 55 patients with acquired immunodeficiency syndrome (AIDS) were reviewed for evidence of pulmonary emphysema. While the average age of patients in this series was 38 years, 25 of the 55 patients, or 45%, demonstrated CT evidence of emphysema. CT findings suggestive of emphysema included areas of low-attenuation, blebs and/or vascular disruption. The authors conclude there is an increased incidence of CT-detectable pulmonary emphysema that is premature for age in patients with AIDS. Destruction of pulmonary parenchyma may represent the response of the lung to repeated pulmonary infections or may be a direct result of the human immunodeficiency virus

2015-10-01

Full Text Available Women in Sub-Saharan Africa are disproportionately affected by the virus and constitute 60% of the total HIV/AIDS infections in this region. Current recommendations endorse the involvement of people living with HIV in the development of programmes for people living with the virus. The purpose of the study was to explore and describe the health literacy needs of women living with HIV. The research design was qualitative, explorative, descriptive and contextual. After women living with HIV/AIDS were sampled purposively, semi-structured interviews were conducted with eight women and qualitative content analysis done. The findings revealed that the women expressed a need to increase their knowledge about HIV/AIDS. The knowledge they needed ranged from basic pathophysiology about HIV/AIDS, to the impact of HIV/AIDS on their health, to an awareness of the modes of HIV transmission and methods of protecting others from being infected. Other important health literacy needs related to self-care and correct antiretroviral use. A need for psychosocial skills was also identified in order for women to build and maintain their relationships. Recommendations were made for nursing practice, education and further research, based on these findings.

Differences in gay men's AIDS risk knowledge and behavior patterns in high and low AIDS prevalence cities.

St Lawrence, J S; Hood, H V; Brasfield, T; Kelly, J A

1989-01-01

Several studies have found reductions in acquired immunodeficiency syndrome (AIDS) risk practices among gay men in high AIDS-prevalence cities since the start of the AIDS crisis. Much less is known about risk behavior patterns among gay men in smaller cities, where AIDS cases are less common and the prevalence of human immunodeficiency virus infection is relatively lower. In the study, men entering gay bars in three cities, one large and two small, completed anonymous surveys of sexual practices and AIDS risk knowledge. Men in high AIDS-prevalence areas were found to have had a greater number of sexual partners, were more knowledgeable about AIDS, were much more likely to engage in low-risk practices (such as mutual masturbation or body rubbing), and had unprotected anal intercourse less frequently than gay men in smaller cities. The most common sexual activity among gay men in the larger city was mutual masturbation, a low-risk practice. The most common sexual activity among gay men in the smaller cities was unprotected anal intercourse. Increased efforts are needed to educate gay men and to promote risk behavior changes among those living in smaller cities and in communities outside the prominent AIDS epicenters.

The risk of cancer is substantially increased in HIV-infected patients. However, little is known about non-AIDS-defining cancers (NADCs) without an infectious etiology. A total of 5,090 HIV-infected patients registered in the Local Health Authority (LHA) of Brescia and receiving primary care at our clinic were included in a retrospective (1999-2009) analysis. The cancer diagnoses were obtained through a record-linkage procedure between our database and the LHA general database and population-based Cancer Registry of LHA. We compared risks of these malignancies with those of the general population living in the same health area by using age-standardized incidence ratios (SIRs). Poisson regression analysis was used to assess factors associated with non-virus-related NADCs. We recorded an increase in the SIR of non-virus-related NADCs over time, with 138 cancers diagnosed in 131 patients. The mean incidence rate was 42.6/10,000 person years and the median age at the diagnosis was 49 (range, 28-78) years old. Stratifying for gender, only HIV-infected males had an increased risk of non-virus-related NADCs [SIR=1.86; 95% confidence interval (CI), 1.55-2.26]. Risk was higher for lung (SIR=3.59; 95% CI, 2.36-5.45) and testis cancer (SIR=3.11; 95% CI, 1.48-6.52). However,, cancers of the prostate and breast in HIV-positive men and women were null (SIR=1.10; 95% CI, 0.53-2.32 and SIR=0.91; 95% CI, 0.47-1.74, respectively). The only predictors of non-virus-related NADCs included older age [incidence rate ratio (IRR)=1.10; 95% CI, 1.08-1.12 per each additional year, prisk of non-virus-related NADCs compared to the general population. However, the use of cART appeared to be beneficial in protecting against the development of these malignancies.

Transforming growth factor (TGF)-β inhibits hepatitis B virus (HBV) replication although the intracellular effectors involved are not determined. Here, we report that reduction of HBV transcripts by TGF-β is dependent on AID expression, which significantly decreases both HBV transcripts and viral DNA, resulting in inhibition of viral replication. Immunoprecipitation reveals that AID physically associates with viral P protein that binds to specific virus RNA sequence called epsilon. AID also binds to an RNA degradation complex (RNA exosome proteins), indicating that AID, RNA exosome, and P protein form an RNP complex. Suppression of HBV transcripts by TGF-β was abrogated by depletion of either AID or RNA exosome components, suggesting that AID and the RNA exosome involve in TGF-β mediated suppression of HBV RNA. Moreover, AID-mediated HBV reduction does not occur when P protein is disrupted or when viral transcription is inhibited. These results suggest that induced expression of AID by TGF-β causes recruitment of the RNA exosome to viral RNP complex and the RNA exosome degrades HBV RNA in a transcription-coupled manner.

For the medical diagnostic imaging specialist in general, and for the nuclear medicine physician specifically, the AIDS epidemic has generated an enormous demand to develop a means of making early diagnoses of the complications of AIDS. For the most part this has meant the early detection, and when possible, the characterization of the opportunistic infections and neoplasms that are a major source of morbidity and mortality for the AIDS patient. Detection of opportunistic infections has been helpful in reclassifying HIV-seropositive patients as having AIDS. This paper reports on nuclear medicine used to evaluate the efficacy and the complications of treatment in human immunodeficiency virus infection. Most recently, functional brain imaging has been used for the diagnosis and follow-up of the AIDS dementia complex

We analysed cumulative disease frequencies in the first 231 adult Danish AIDS patients with life tables. There was a certain hierarchical pattern in the occurrence of complicating diseases. Herpes zoster, Kaposi's sarcoma and Pneumocystis carinii pneumonia were early manifestations, whereas...... diseases caused by cytomegalovirus and atypical mycobacteria tended to occur later in the course of AIDS. Compared with all other AIDS patients, homosexual men were more likely to develop Kaposi's sarcoma, cytomegalovirus chorioretinitis and mucocutaneous herpes simplex virus infection. The proportion...... of patients who developed particular diseases changed with calendar time. Most striking was a three to fourfold decrease in diseases caused by cytomegalovirus. In conclusion, the study showed that disease frequencies in patients with AIDS may vary with the patients risk behaviour and duration of AIDS...

AIDS (acquired immune deficient syndrome) is a deadly human viral infectious disease caused by HIV (human immune-deficient virus) infection. Almost every AIDS patient losses his/her life before mid 1990s. AIDS was once the 1st disease killer in US (1993). After one decade hard work, antiviral drug cocktails-high active anti-retroviral therapy (HAART) have been invented for almost all HIV infection treatments. Due to the invention of HAART, 80-90% HIV/AIDS patients still effectively response to HAART for deadly AIDS episode controls and life saving. Yet, this type of HIV therapeutics is incurable. HIV/AIDS patients need to take HAART medications regularly and even life-long. To counteract this therapeutic drawback, more revolutionary efforts (different angles of therapeutic modes/attempts) are urgently needed. In this article, the major progresses and drawbacks of HIV/AIDS chemotherapy (HAART) to HIV/AIDS patients have been discussed. Future trends (updating pathogenesis study, next generations of drug developments, new drug target discovery, different scientific disciplinary and so on) are highlighted.

Human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) had a major impact on health problemin Indonesia. HIV type 1 (HIV-1) epidemic is currently infected with HIV viruses developing rapidly in Indonesia.Papua provinces have the highest prevalence rate of human immunodeficiency virus type 1 (HIV-1) infection in Indonesia; however, data on opportunistic infection of HIV-1 are limited. The study using medical records as a research sample was conducted among HIV patients from January 2013 - December 2014 in Sele be Solu hospital among 49 patients. Opportunistic infections commonly occur in HIV-infected patients. The aim of the study was to know theprevalence of opportunistic infection among HIV positive patients in West Papua. Forty-nine HIV-1 patients were collected in Sele be Solu Hospital, West Papua.Opportunistic infection was identified such as tuberculosis, tuberculosis Pulmo, tuberculosis and candidiasis, candidiasis and diarrhea. The clinical sign appeared in HIV infected patients such as itchy, cough and loss weight. The prevalence of opportunistic infection indicated the necessity of monitoring the opportunistic infection of HIV/AIDS patients in Indonesia.

Oral health care of patients with human immunodeficiency virus (HIV)/acquired immune-deficiency syndrome (AIDS) is a growing area of concern. Information on HIV- and AIDS-related knowledge among dental students provides a crucial foundation for efforts aimed at developing an appropriate dental curriculum on HIV and AIDS. The purpose of this study was to assess the knowledge and attitude of Indian clinical dental students towards the treatment of patients with HIV/AIDS and perceived sources of information regarding HIV-related issues. Data were collected from clinical dental students (third year, fourth year and internship) from three dental institutions in Delhi National Capital Region (NCR). The questions assessed the knowledge and attitude towards treatment of patients with HIV and the perceived source of information related to HIV. The willingness to treat HIV-positive patients among dental students was 67.0%, and 74.20% were confident of treating a patient with HIV/AIDS. The potential problems in rendering treatment to these patients were effect on the attitude of other patients (49.90%) and staff fears (52.50%). The correct knowledge regarding the infection-control practice (barrier technique) was found among only 15.50% of respondents. The respondents had sufficient knowledge regarding the oral manifestations of HIV/AIDS. There was no correlation between the knowledge and attitude score, demonstrating a gap between knowledge and attitude among dental students regarding treatment of HIV-infected patients. Appropriate knowledge has to be delivered through the dental education curriculum, which can instil confidence in students about their ability to manage HIV-positive patients. © 2014 FDI World Dental Federation.

Herfst, S; Imai, M; Kawaoka, Y; Fouchier, R A M

2014-01-01

Influenza A viruses cause yearly epidemics and occasional pandemics. In addition, zoonotic influenza A viruses sporadically infect humans and may cause severe respiratory disease and fatalities. Fortunately, most of these viruses do not have the ability to be efficiently spread among humans via aerosols or respiratory droplets (airborne transmission) and to subsequently cause a pandemic. However, adaptation of these zoonotic viruses to humans by mutation or reassortment with human influenza A viruses may result in airborne transmissible viruses with pandemic potential. Although our knowledge of factors that affect mammalian adaptation and transmissibility of influenza viruses is still limited, we are beginning to understand some of the biological traits that drive airborne transmission of influenza viruses among mammals. Increased understanding of the determinants and mechanisms of airborne transmission may aid in assessing the risks posed by avian influenza viruses to human health, and preparedness for such risks. This chapter summarizes recent discoveries on the genetic and phenotypic traits required for avian influenza viruses to become airborne transmissible between mammals.

There is little detailed information on human immunodeficiency virus (HIV) amongst older adults in Singapore. A retrospective study of 121 consecutive referrals of patients presenting for HIV care was conducted. Demographic, clinical and laboratory variables were collected. A prognostic model derived from the North American Veterans' Affairs Cohort Study (VACS) was used to estimate prognosis. The median age at presentation was 43 (range, 18 to 76). Thirty-eight patients (31%) were aged 50 or older and 106 patients (88%) were male. Older patients were more likely to be of Chinese ethnicity (P = 0.035), married (P = 0.0001), unemployed or retired (P = 0.0001), and to have acquired their infection heterosexually (P = 0.0002). The majority of patients in both groups were symptomatic at presentation. Eighty-one (67%) had CD4 counts less than 200 at baseline with no observable differences in HIV ribonucleic acid (RNA) or clinical stage based on age. Non-Acquired Immunodeficiency Syndrome (AIDS) morbidity was observed more frequently amongst older patients. The estimated prognosis of patients differed significantly based on age. Using the VACS Index and comparing younger patients with those aged 50 and above, mean 5 year mortality estimates were 25% and 50% respectively (P HIV/AIDS cases and present with more non-AIDS morbidity. This confers a poor prognosis despite comparable findings with younger patients in terms of clinical stage, AIDS-defining illness, CD4 count and HIV viral load.

In this paper, we present an Human Immunodeficiency Virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS) drug-resistant model using an ordinary differential equation (ODE) model on scale-free networks. We derive the threshold for the epidemic to be zero in infinite scale-free network. We also prove the stability of disease-free equilibrium (DFE) and persistence of HIV/AIDS infection. The effects of two immunization schemes, including proportional scheme and targeted vaccination, are studied and compared. We find that targeted strategy compare favorably to a proportional condom using has prominent effect to control HIV/AIDS spread on scale-free networks.

The article describes the progress of medical knowledge which has been observed since the finding and discovery of the first case of the immune deficiency syndrome in the world in 1981. During this period the methods of diagnosis and treatment of HIV/AIDS has changed significantly. The progress in this area of examinations which is presently achieved allows unambiguous diagnosis of the virus and the disease. The recognition of the pathogenesis of the HIV and AIDS enabled the beginning of the studies on the medicines having antiretroviral properties. The utilization of the potential of the currently used medicines inhibits the progress of the disease and, in consequence, the elongation of the patients' life span. However, despite excessive clinical experiments in numerous research centres world-wide, until now there has not been found an effective medicine which could totally eradicate this virus from the body nor the vaccine which could prevent the further spread of this virus in the world.

Olsen, W.L.; Longo, F.; Norman, D.

1987-01-01

Autopsy reports have shown white-matter abnormalities from infection of the brain by the human immunodeficiency virus (HIV), the agent that causes acquired immunodeficiency syndrome (AIDS). The authors observed abnormal signal on T2-weighted images in the white matter of approximately one third of all AIDS patients. Of 50 patients with white-matter lesions, approximately two thirds had no clinical or biopsy evidence of cytomegalovirus, toxoplasmosis, PML, or lymphoma. Several patients were shown at autopsy to have isolated evidence of HIV encephalitis. The authors conclude that white-matter lesions are common in AIDS and are frequently caused by infection with HIV. Some MR findings may be helpful in characterizing these lesions, but the various etiologies are often indistinguishable

Morphological imaging, based on the use of various techniques including ultrasound, X-ray computed tomography (CT), and magnetic resonance imaging (MRI), plays an important role in the characterization, diagnosis and follow-up of patients with Human Immunodeficiency Virus (HIV) infection and Acquired Immunodeficiency Syndrome (AIDS). While the presence of thoracic infections, the most frequently observed illnesses in AIDS patients, can best be performed by using conventional chest films and CT, the assessment of cerebral involvement in AIDS patients - characterized by the presence of focal masses, demyelination, meningitis, and infarction - is best achieved using MRI. The work-up of patients with gastrointestinal symptoms should include the use of ultrasound for the evaluation of visceral involvement and lymphadenopathy, completed by CT to further characterize pathologic conditions in either the bowel or visceral organs. Ultrasound is the screening exam of choice in AIDS patients with suspected renal disease, but other methods may be necessary for the assessment of the complications due to pharmacological treatment. Musculoskeletal complications may require the combined use of all the above methods, since they may be caused by infections, tumors and rheumatologic illness. The use of the radiographic methods for the detection of the numerous forms of infections and malignancies in AIDS patients is described in detail for the various body districts

Full Text Available Objectives. To assess participants’ knowledge about HIV/AIDS and to identify the factors associated with HIV/AIDS in Sudan. Methods. Observational cross-sectional study carried out at Omdurman National Voluntary Counseling and Testing Centre, Sudan covered 870 participants. Sociodemographic data as well as information related to sexual behavior were collected. Results. Most of the respondents were knowledgeable about the true transmission modes for AIDS virus. Very few respondents knew someone infected with AIDS (4.5%, died of AIDS (8.1%, accepted to live with someone infected with AIDS (4.7% or to work with someone infected with AIDS (2.1%. Regarding sexual behavior, 96.5% had reported their first sexual experience between 20 and 30 years, with 85.7% reporting one or two partners, and only 1.8% reported using condom. Multivariate logistic regression showed that circumcision, religion, marital status, age at first sex, number of sexual partners, education level, and misconception of knowledge are the main risk factors associated with HIV/AIDS. Conclusion. Our results showed that a number of diversity risk factors were associated with HIV/AIDS. It is unlikely that a holistic approach will be found to immediately change sexual-risk-relating behavior. Interventions including sustained educational programs, promotion of condom, and encouragement of voluntary testing and active involvement of the country’s political and religious leaders will be needed to alleviate this problem.

Human immunodeficiency virus type 1 (HIV-1) is the major cause of acquired immunodeficiency syndrome (AIDS) in humans, where the immune system totally succumbs to the virus. A large proportion of the AIDS infected belong to developing countries and AIDS prevalence is intensified by severe poverty, malnutrition, and famine; fatal illnesses with a scorn shortage of medical amenities complemented with the lack of education and development. Current Pakistani health system setting is in a dire need of improvement. Low literacy rates, high birth rates, and associated maternal mortality plus a lack of clean drinking water and appropriate sanitation system have a serious impact on general living conditions contributing to a relatively short lifespan. HIV is, therefore, becoming a growing health concern in Pakistan with a rapid rise in the reported cases. AIDS is most prevalent among injection drug users (IDUs), male/female sex workers, and unchecked deported migrant workforce. To combat this virus, the Pakistan Government has been working hard over the past few years with local bodies and international organizations in an effort to combat this menace. This review aims to discuss the risk factors for the rise of this epidemic in the country and the recommendations, efforts to be done to address this alarming issue.

Human immunodeficiency virus (HIV) infection is an epidemic worldwide, despite the marked benefits of antiretroviral therapy (ARV) in reducing severe HIV-associated dementia. A milder form of neurocognitive disorders are still prevalent and remain a challenge. This study aimed to determine the correlation between plasma cluster of differentiation 4 (CD4) lymphocyte, duration of ARV treatment, opportunistic infections, and cognitive function in HIV-AIDS patients. A cross-sectional study involving 85 HIV-AIDS patients was conducted at Adam Malik General Hospital Medan, Indonesia. All subjects were subjected to physical, neurologic examination and Montreal Cognitive Assessment-Indonesian Version (MoCA-INA) to assess cognitive function and measurement of lymphocyte CD4 counts. Out of the 85 subjects evaluated, the proportion concerning sexes include 52 males (61.2 %) and 33 females (38.8%). The mean age was 38.53 ± 9.77 years old. There was a significant correlation between CD4 lymphocyte counts and MoCA-INA score (r = 0.271, p = 0.012), but there was no significant correlation between duration of ARV treatment and MoCA-INA score. There was also no difference in MoCA-INA score based on the presence of opportunistic infection. Lymphocyte CD4 count was independently correlated with cognitive function in HIV-AIDS patients.

1987-01-01

A mathematical computer model of the spread of the AIDS epidemic in the US is being developed at Los Alamos National Laboratory. This model predicts the spreading of the HIV infection, and subsequent development of clinical AIDS in various population groups. These groups are chosen according to age, frequency and type of sexual contact, population density, and region of the country. Type of sexual contact includes not only the heterosexual, homosexual differentiation but also repeated contacts with such primary partners as spouses. In conjunction with the computer model, we are developing a database containing relevant information on the natural history of the viral infection, the prevalence of the infection and of clinical AIDS in the population, the distribution of people into sexual behavior groups as a function of age and information on interregional contacts. The effects of variable infectiousness and sexual activity during the long period from infection to disease are found to have a major impact on the predictions of the model. 24 refs., 5 figs.

Here we review recent genetic advances that have questioned traditional wisdom regarding the origins of virulent Feline infectious peritonitis (FIP) diseases, the pathogenic potential of Feline Immunodeficiency Virus (FIV) in wild non-domestic Felidae species, and the restriction of Feline Leukemia Virus (FeLV) mediated immune impairment to domestic cats rather than other Felidae species. The most recent interpretations indicate important new evolutionary conclusions implicating these deadly infectious agents in domestic and non-domestic felids.

The spectrum of pathology affecting the central nervous system (CNS) in patients suffering from acquired immunodeficiency syndrome (AIDS) includes not only the human immunodeficiency virus (HIV) infection itself but also opportunistic infections and tumors secondary to AIDS. Despite progress in antiretroviral therapy and the subsequent decrease in the incidence of associated diseases, opportunistic infections and tumors secondary to the HIV infection continue to be the limiting factor in terms of survival with AIDS. Therefore, the therapeutic aim is permanent antiretroviral therapy as well as early diagnosis and treatment of opportunistic infections. Magnetic resonance imaging is often the diagnostic method of choice in suspected CNS pathology of HIV patients. In the following, the typical clinical and radiological features of several AIDS-related pathologies are presented and discussed. (orig.)

The spectrum of pathology affecting the central nervous system (CNS) in patients suffering from acquired immunodeficiency syndrome (AIDS) is broad and comprises predominantly opportunistic infections and neoplasms. It is estimated that approximately one-third of all patients with AIDS develop neurological complications. The organisms responsible for AIDS are human retroviruses: primarily the human immunodeficiency virus type 1 (HIV). In this review we shall focus on the neurological complications of HIV and AIDS which are applicable to the more frequently occurring intracranial infective organisms. Attention will be paid specifically to those CNS manifestations occurring in the adult HIV and AIDS population as infection in the paediatric HIV and AIDS group, although bearing some similarities, demonstrates some important differences.

Youths aged 13 to 24 years old living with human immunodeficiency virus (HIV) are less likely than adults to receive the health and prevention benefits of HIV treatments, with only a small proportion having achieved sustained viral suppression. These age-related disparities in HIV continuum of care are owing in part to the unique developmental issues of adolescents and young adults as well as the complexity and fragmentation of HIV care and related services. This article summarizes a national, multiagency, and multilevel approach to HIV care for newly diagnosed youths designed to bridge some of these fragmentations by addressing National HIV/AIDS Strategy goals for people living with HIV. Three federal agencies developed memoranda of understanding to sequentially implement 3 protocols addressing key National HIV/AIDS Strategy goals. The goals were addressed in the Adolescent Trials Network, with protocols implemented in 12 to 15 sites across the United States. Outcome data were collected from recently diagnosed youth referred to the program. Cross-agency collaboration, youth-friendly linkage to care services, community mobilization to address structural barriers to care, cooperation among services, proportion of all men who have sex with men who tested, and rates of linkage to prevention services. The program addressed National HIV/AIDS Strategy goals 2 through 4 including steps within each goal. A total of 3986 HIV-positive youths were referred for care, with more than 75% linked to care within 6 weeks of referral, with almost 90% of those youths engaged in subsequent HIV care. Community mobilization efforts implemented and completed structural change objectives to address local barriers to care. Age and racial/ethnic group disparities were addressed through targeted training for culturally competent, youth-friendly care, and intensive motivational interviewing training. A national program to address the National HIV/AIDS Strategy specifically for youths can

How to develop a company AIDS policy.

Bompey, S H

1986-07-01

It is for most businesses only a matter of time before they will have experience with Acquired Immune Deficiency Syndrome (AIDS), and the experience could be very costly for companies which fail to implement an effective AIDS policy. Potential AIDS problems include: antidiscrimination suits based on firing or failing to hire an individual who had AIDS or carries the AIDS virus antibodies; defamation suits from employees who are wrongly identified; disability claims that do not fit the pattern for other diseases; civil rights penalties in some situations when AIDS victims are prevented from working; and run-ins with the Occupational Safety and Health Administration or the National Labor Relations Board if healthy workers refuse to work alongside AIDS victims. A company needs to think through its AIDS policy, but that does not mean establishing a "special" AIDS policy which may create paranoia among employees. The best approach is to develop a health policy that includes all catastrophic illnesses, not just AIDS. There have been few court decisions involving AIDS because AIDS is a recent illness, victims often do not live long enough to pursue the matter, and it often pays to settle AIDS cases out of court. Employers need to know that judges, administrative agencies, and arbitrators take the position that AIDS is a disability. As such, AIDS is treated under the anti-handicap discrimination laws on the books of most states. Additionally, the Federal Rehabilitation Act of 1973 prohibits discrimination against the disabled by companies that contract with the federal government or receive federal financial assistance. It usually is illegal to discriminate against the disabled workers, and in some states against workers who are perceived to have a disability. The best defense against the fear of working alongside and AIDs sufferer is education.

Although considerable attention has been placed on the role of prostitutes in the AIDS epidemic, little attention has been directed to features of prostitutes' work lives which are relevant to the control of AIDS. This article reviews several aspects of prostitution in the United States which have implications for control of the epidemic. The article first reviews the epidemiology of human immunodeficiency virus (HIV) infection among prostitutes. The legalized system of prostitution in Nevada serves as a basis for comparison to illegal prostitution. This article examines the effectiveness of mandatory testing of prostitutes for monitoring and controlling the epidemic. And finally, a peer education approach as a means to control HIV infection among prostitutes is explored.

AIDS: there's hope.

1993-06-01

In 1993, 10 years after realizing that AIDS posed a threat to the future of mankind, social mobilization will improve the odds against AIDS. The objective is to create awareness about the virus, and to affect positive behavioral change through advocacy, communication, and grass-roots actions. The first goal is to change the societal attitude about the status of youth and women in order to understand that gender inequality fuels the pandemic. They are the most vulnerable groups, therefore their economic and social power must be improved. The Convention on the Rights of the Child and the Convention on the Elimination of All Forms of Discrimination against Women constitute a platform for broader action by governmental, nongovernmental, and religious institutions. In addition, these organizations need strong allies in society: 1) the media, which can communicate the importance of youth, women, and attitudes in the epidemic; 2) religious leaders, who can be powerful sources of advocacy for change in attitudes as well as support and care for AIDS-affected individuals and families; 3) policy makers, who can be crucial in changing existing policies and altering the allocation of government resources to youth and women; 4) human rights organizations, which play an important role in promoting the concept of health as a human right and for enhancing the understanding of AIDS in the context of discrimination and poverty; 5) the private sector, including commerce and industry, which can promote changes in attitude within the work force and AIDS prevention initiatives; and 6) parent-teacher groups and models for youth, who can educate them about socially acceptable and unacceptable behavior and can empower them to make responsible behavior choices.

Full Text Available HIV infection is associated with immune-compromised and rising in opportunistic infection (secondary infection. Therefore, the number of mortality caused by HIV/AIDS is increasing. The use of ARV and development of HIV/AIDS management are expected to suppress the progress of HIV infection into AIDS and, therefore, the mortality can be diminished, while in fact most of the patients eventually suffer from AIDS due to secondary infection that commonly causes death. There should be a management by analysing microorganisms that trigger secondary infection. The method of this study was observational descriptive with cross sectional design. HIV infected blood samples were using ELISA Antibody (IgG and IgM and Polymerase Chain Reaction (PCR on laboratory test. The result showed correlation between HIV/AIDS severity and the amount and types of secondary infection. The most common secondary infections were toxoplasm (96.77%, hepatitis C (22.58%, tuberculosis (19.35%, and hepatitis B (3.22%. Other less frequent secondary infections, which were quite difficult to diagnose and not commonly found in Indonesia, were West Nile Virus (25.81%, Japanese Encephalitis Virus (3.22%, and Enterovirus (3.22%. Due to MDGs (Millenium Development Goals target and the results above, researchers are highly demanded to contribute in decreasing mortality related to AIDS through early detection of secondary infection,including type of infection which have not been commonly found in Indonesia, such as West Nile Virus and Nipah Virus. The discovery of secondary infection in this study was not enough to suppress the occurrence of infection in HIV/AIDS patients. Antimicrobes and good nutrition are required. Moreover, there should be either a primary or secondary prophylaxis to prevent secondary infection that raises the number of mortality and morbidity of HIV/AIDS patients. The result of this study was to meet the target of MDGs by establishing new policies in handling HIV/AIDS

Currently, there is no cure and no preventive vaccine for HIV/AIDS. Combination antiretroviral therapy has dramatically improved treatment, but it has to be taken for a lifetime, has major side effects and is ineffective in patients in whom the virus develops resistance. Nanotechnology is an emerging multidisciplinary field that is revolutionizing medicine in the 21st century. It has a vast potential to radically advance the treatment and prevention of HIV/AIDS. In this review, we discuss the challenges with the current treatment of the disease and shed light on the remarkable potential of nanotechnology to provide more effective treatment and prevention for HIV/AIDS by advancing antiretroviral therapy, gene therapy, immunotherapy, vaccinology and microbicides.

Stepping toward a Macaque Model of HIV-1 Induced AIDS

Directory of Open Access Journals (Sweden)

Jason T. Kimata

2014-09-01

Full Text Available HIV-1 exhibits a narrow host range, hindering the development of a robust animal model of pathogenesis. Past studies have demonstrated that the restricted host range of HIV-1 may be largely due to the inability of the virus to antagonize and evade effector molecules of the interferon response in other species. They have also guided the engineering of HIV-1 clones that can replicate in CD4 T-cells of Asian macaque species. However, while replication of these viruses in macaque hosts is persistent, it has been limited and without progression to AIDS. In a new study, Hatziioannou et al., demonstrate for the first time that adapted macaque-tropic HIV-1 can persistently replicate at high levels in pigtailed macaques (Macaca nemestrina, but only if CD8 T-cells are depleted at the time of inoculation. The infection causes rapid disease and recapitulates several aspects of AIDS in humans. Additionally, the virus undergoes genetic changes to further escape innate immunity in association with disease progression. Here, the importance of these findings is discussed, as they relate to pathogenesis and model development.

Faith-based organizations are in a unique position to provide resilience-enhancing efforts for persons living with human immunodeficiency virus/AIDS. Many persons living with human immunodeficiency virus/AIDS report having a strong faith or religious affiliation, with a large percentage attending church services on a regular basis. Faith-based organizations can use these factors to reach out to these individuals and effectively promote health, well-being, education, and support.

Critical amino acids within the human immunodeficiency virus type 1 envelope glycoprotein V4 N- and C-terminals contribute to virus entry.

Directory of Open Access Journals (Sweden)

Yan Li

Full Text Available The importance of the fourth variable (V4 region of the human immunodeficiency virus 1 (HIV-1 envelope glycoprotein (Env in virus infection has not been well clarified, though the polymorphism of this region has been found to be associated with disease progression to acquired immunodeficiency syndrome (AIDS. In the present work, we focused on the correlation between HIV-1 gp120 V4 region polymorphism and the function of the region on virus entry, and the possible mechanisms for how the V4 region contributes to virus infectivity. Therefore, we analyzed the differences in V4 sequences along with coreceptor usage preference from CCR5 to CXCR4 and examined the importance of the amino acids within the V4 region for CCR5- and CXCR4-tropic virus entry. In addition, we determined the influence of the V4 amino acids on Env expression and gp160 processing intracellularly, as well as the amount of Env on the pseudovirus surface. The results indicated that V4 tended to have a shorter length, fewer potential N-linked glycosylation sites (PNGS, greater evolutionary distance, and a lower negative net charge when HIV-1 isolates switched from a coreceptor usage preference for CCR5 to CXCR4. The N- and C-terminals of the HIV-1 V4 region are highly conserved and critical to maintain virus entry ability, but only the mutation at position 417 in the context of ADA (a R5-tropic HIV-1 strain resulted in the ability to utilize CXCR4. In addition, 390L, 391F, 414I, and 416L are critical to maintain gp160 processing and maturation. It is likely that the hydrophobic properties and the electrostatic surface potential of gp120, rather than the conformational structure, greatly contribute to this V4 functionality. The findings provide information to aid in the understanding of the functions of V4 in HIV-1 entry and offer a potential target to aid in the development of entry inhibitors.

The rapid emergence of AIDS in humans during the period between 1980 and 2000 has led to extensive efforts to understand more fully similar etiologic agents of chronic and progressive acquired immunodeficiency disease in several mammalian species. Lentiviruses that have gene sequence homology with human immunodeficiency virus (HIV) have been found in different species (including sheep, goats, horses, cattle, cats, and several Old World monkey species). Lentiviruses, comprising a genus of the Retroviridae family, cause persistent infection that can lead to varying degrees of morbidity and mortality depending on the virus and the host species involved. Feline immunodeficiency virus (FIV) causes an immune system disease in domestic cats (Felis catus) involving depletion of the CD4+ population of T lymphocytes, increased susceptibility to opportunistic infections, and sometimes death. Viruses related to domestic cat FIV occur also in a variety of nondomestic felids. This is a brief overview of the current state of knowledge of this large and ancient group of viruses (FIVs) in South America.

More than decades have already elapsed since human immunodeficiency virus (HIV) was identified as the causative agent of acquired immunodeficiency syndrome (AIDS). The HIV has since spread to all parts of the world with devastating effects. In sub-saharan Africa, the HIV/AIDS epidemic has reached unprecedented proportions. Safe, effective and affordable HIV/AIDS vaccines for Africans are therefore urgently needed to contain this public health problem. Although, there are challenges, there are also scientific opportunities and strategies that can be exploited in the development of HIV/AIDS vaccines for Africa. The recent RV144 Phase III trial in Thailand has demonstrated that it is possible to develop a vaccine that can potentially elicit modest protective immunity against HIV infection. The main objective of this review is to outline the key scientific opportunities, challenges and strategies in HIV/AIDS vaccine development in Africa. PMID:26185576

Gendered differences in AIDS and AIDS-related cause of death among youth with secondary education in South Africa, 2009-2011.

De Wet, Nicole

2016-12-01

The prevalence of human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) is higher among females than males in Sub-Saharan Africa. Education is associated with better health outcomes. For this and other reasons, African countries have made a concerted effort to increase youth education rates. However, in South Africa males have lower secondary education rates than females, yet females have a higher prevalence of HIV/AIDS. This study examines if a gender disparity exists in AIDS mortality rates among youth with secondary education in South Africa. This study uses descriptive statistics and life table techniques. A sample of 4386 deaths of youth with secondary education is used. Of this total sample, 987 deaths were among males and 340 were among females with secondary education. This study shows that AIDS mortality is higher among females than males in South Africa. Males and females with secondary education have lower AIDS mortality than all males and females in the population, yet the rates are higher for females. Using cause-deleted life tables, the probability of youth dying from HIV/AIDS practically disappears for both males and females. Odds ratio calculations show that secondary education does not have a protective effect from AIDS mortality among male and female youth. Given the gendered difference in AIDS mortality among youth with secondary education, efforts to increase secondary education among males and further research into other factors exacerbating AIDS mortality among females with secondary education is needed in the country.

Neurological complications in patients with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) are still common, even in the era of highly active antiretroviral therapy. Opportunistic infections, immune reconstitution, the virus itself, antiretroviral drugs and neurocognitive disorders have to be considered when establishing the differential diagnosis. Toxoplasmic encephalitis remains the major cause of space-occupying lesions in the brain of patients with HIV/AIDS; however, spinal cord involvement has been reported infrequently. Here, we review spinal cord toxoplasmosis in HIV infection and illustrate the condition with a recent case from our hospital. We suggest that most patients with HIV/AIDS and myelitis with enhanced spine lesions, multiple brain lesions and positive serology for Toxoplasma gondii should receive immediate empirical treatment for toxoplasmosis, and a biopsy should be performed in those cases without clinical improvement or with deterioration.

The Indian Health Organization projected the number of deaths per day due to AIDS by the year 2000 at 10,000. An interdisciplinary international conference was held in New Delhi to draft an international law governing the issues related to AIDS. Human freedom and public health policies are the most affected by this disease. In the absence of an international AIDS law, judicial verdicts set precedents and could have serious ramifications. A participant from the John Marshall Law School, Chicago, suggested that instead of making new laws, the existing ones from the colonial past should be repealed. This includes Section 377 of the Indian Penal Code, which provides criminal sanctions against those who indulge in unnatural relations with man, woman, or animal. Penalizing homosexuality will only perpetuate clandestine relations and spread the virus into their families. Another participant seconded this motion stating that even a sex worker must be protected from abuse and indignity. The National AIDS Control Organization responded to the criticism that the government had not utilized all the World Bank funds allocated for anti-AIDS projects. The trends of the epidemic were the most important indicators not just the numbers. In Manipur and Mizoram, infection was almost entirely due to injecting drug use. The Saheli project undertaken in the red-light areas of Bombay encompassed brothel owners and prostitutes, which could be replicated in other areas. Because existing government policies were focusing on prevention, there was no protection of an HIV-infected individual's privacy, one participant from Madras stated. The confidentiality issue was also echoed by a US participant. The New Delhi Declaration and Action Plan on HIV/AIDS was also discussed. It forbids discrimination in employment, education, housing, health care, social security, travel, and marital and reproductive rights. Providing sterile needles and ensuring the safety of the blood supply were other concerns

1988-06-01

Acquired immunodeficiency syndrome (AIDS) was selected as the subject for the 1st annual George H Gallup Memorial Survey. This survey, conducted in August 1987-April 1988 in 35 countries, measured the level of awareness of AIDS, the extent of concern about AIDS, knowledge, changes in behavior resulting form the AIDS epidemic, and attitudes toward people with AIDS. Overall, the poll's findings attest to the effectiveness of the health education efforts of governmental and nongovernmental organizations. Awareness that AIDS poses an urgent international health problem was almost universal in the 35 samples. In about half of these countries, AIDS was identified as the most important national health problem; in the remaining countries, AIDS was ranked 2nd to cancer. The proportion of respondents expressing a fear of personally contracting the AIDS virus ranged from lows of under 10% in most of Europe to a high of 45% among South African blacks. A majority of respondents in the US, Colombia, the Philippines, Brazil, Nigeria, Ecuador, El Salvador, and Chile believed that AIDS will soon spread beyond current risk groups to the general population. Despite widespread awareness of the grave threat posed by AIDS, insufficient numbers of respondents reported that they had made specific behavioral changes intended to protect themselves form HIV infection. Overall, about half of those interviewed indicated they are now more cautious in their choice of sexual partners; similarly, about half are using condoms more or for the 1st time.

Background Human parvovirus B19 (B19) is a common pathogen which causes a variety of diseases. Persistent B19 infection is related to the degree of host immunodeficiency in patients with human immunodeficiency virus (HIV) infection. However, the existence, loading, virus evolution and distribution of B19 in Chinese HIV-positive patients have not been determined. Materials and methods. We investigated 573 HIV-positive blood donors and AIDS patients in Sichuan, China in the last two decades. Bl9-specific serology and quantitative polymerase chain reaction were used to determine the prevalence of B19/HIV co-infection. Viral genome fragments were subjected to phylogeny and haplotype analysis. Results B19 genomic DNA was found in 26 of 573 (4.5%) HIV-positive individuals, a higher prevalence than in blood donors. DNA levels ranged from 5.3×102–1.1×105 copies/mL. The seroprevalence of IgG was significantly lower in HIV-positive samples than in HIV-negative blood donors, indicating deficient production of B19-specific IgG in the former. The B19 isolates were genotype-1 subtype B19-1A which formed a monophyletic group; seven distinct haplotypes were discovered with 60% of the B19/HIV co-infected variants sharing one central haplotype. Discussion. This study on the prevalence, phylogeny and distribution of human parvovirus B19 in Sichuan, China, demonstrates the persistence of B19 in the circulation of both immunocompetent and immunocompromised subjects, with implications for blood safety.

Increasing knowledge is an important goal of human immunodeficiency virus (HIV) prevention strategies, although increased knowledge may not be associated with increased preventive behaviors. This study examines the association of (1) objective and subjective acquired immunodeficiency syndrome (AIDS) knowledge, and (2) both objective and subjective AIDS knowledge with HIV testing use. Data are from the 1988 National Health Interview Survey. Objective and subjective knowledge were only moderately correlated. In regression analyses, higher subjective knowledge was significantly associated with higher testing use, but objective knowledge was not. The results are relevant to other preventive behaviors for which knowledge is an important factor.

Full Text Available Abstract HIV (Human immunodeficiency virus transmission has been reduced by protected sex and screening of blood products and other body fluids in the developed countries. It has been reported that Pakistan is at high risk of HIV/AIDS infection but presently the prevalence rate is considerably low. The number of reported cases of HIV/AIDS in Pakistan has been continuously increasing since 1987. By 2010 the total number of registered cases has reached to 6000 and this figure is on the rise with the passage of time. Some serious strategies must be implemented to control this deadly disease.

Urgent action is needed to fight the alarming spread of HIV/AIDS that infected 1.3 million people in Southeast Asia last year alone, Malaysia's foreign minister said July 24, 2000. Syed Hamid said the Association of Southeast Asian Nations (ASEAN) should tackle at regional and national level an epidemic that was taking its most drastic toll among the region's youth. "HIV/AIDS not only represents a major public health and social problem but is a serious challenge to development as well," Syed Hamid told the opening ceremony of ASEAN's 33rd annual foreign ministers' meeting. The crisis requires commitment at the "highest political level," he said, warning that HIV/AIDS could become a transnational problem within the 10-member group. Foreign ministers have recommended their leaders discuss the crisis later this year at an informal summit in Singapore and hold a summit on HIV/AIDS in conjunction with the 7th ASEAN Summit in Brunei next year. "I think people recognized the importance and the adverse impacts on our social development," Syed Hamid told reporters later. "I think it is a real issue that we cannot run away from." Among ASEAN members, Thailand, Cambodia, and Myanmar have some of the highest infection rates in Asia of HIV, the virus that causes AIDS. full text

HIV/AIDS Pandemia — a Problem Requiring Rethinking On the 30th Anniversary of the Discovery of Human Immunodeficiency Virus

Directory of Open Access Journals (Sweden)

Full Text Available Hazard of HIV/AIDS pandemia is greatly underestimated due to lack of understanding of its role in the processes that are not related to medicine. The principal difference between HIV/AIDS pandemia and the pandemic processes, against which the advances were made in the ХХ century, lies in the fact that it is caused by a virus of the retrovirus family. Retroviruses are ancient tools of evolution. They cause epidemia (epizooty, which are the main mechanism of discontinuous evolution of species. This mechanism is implemented by endogenization of retroviruses in the genome of the surviving species and amplification of their genome through the formation of new copies of retroelements; complexity of the genome by the formation of new exons from introns and/or increased number of genes that are alternatively spliced. Evolutionary past of the immune system of multicellular organisms suggests securing her in the process of natural selection as the reservoir with respect to retroviruses. Thanks to the cells of the immune system there is the multiplication and accumulation of exogenous retroviruses to a certain critical mass, which allows some of them to endogenize in the germline of some specimens of infected species and further transmitted vertically, changing its evolutionary trajectory. HIV/AIDS pandemia among the species homo sapiens — a common manifestation of this process in the evolution of primate taxon. Infectious and epidemic processes caused by HIV, are multicomponent non-cyclic processes that have no mechanisms for termination. To fight with them, experience gained in the XX century during smallpox eradication or in when controlling outbreaks of influenza, plague and other cyclical infections is inapplicable. Given in the article data indicate the need to develop self-control strategy to fight against non-cyclic multicomponent epidemic processes.

Judgeo, N; Moalusi, K P

2014-01-01

This study uses Goffman's [1963. Stigma: Notes on the Management of Spoiled Identity, New Jersey, Prentice-Hall] theory of stigma as an intellectual scaffold to help understand the social meaning of HIV/AIDS stigma from People Living with HIV/AIDS. The study adopts a qualitative approach because of its appropriateness for unravelling subjective phenomena such as the experiences of HIV/AIDS stigma. In-depth interviews were conducted with 10 HIV-positive employees of a retailing company located in the Western Cape province of South Africa who volunteered to participate in the study. The participants with the discreditable stigma internalised society's prejudice towards those living with the virus. As a result, the participants relied on self-isolation and social withdrawal to cope with enacted stigma. Managing information about one's status and deciding whether, who, when, etc., to tell are crucial questions. The participants feared being devalued by family, friends, co-workers and the community. In concurrence with Goffman [1963], the HIV/AIDS stigma is seen as about relationships.

Gender and HIV/AIDS: Exploring Men and Vulnerability Towards Effective HIV/AIDS Policy Interventions and Sub-Saharan Africa

Directory of Open Access Journals (Sweden)

2012-06-01

Full Text Available This article examines the dynamics between HIV/Aids gender policy strategies and the socio-political demands on HIV/Aids interventions in sub-Saharan Africa. Gender in HIV/Aids intervention seems inescapable. Nowhere else is this more marked than in the social dimensions of HIV/Aids prevention in sub-Saharan Africa. This has resulted in prevention strategies, which are encumbered by the reality of poverty, gender, access, power and the various debates on behavioural change. The social constructions of gender roles and power relations play a significant role in the region’s HIV /Aids dynamic. To this end, the mainstreaming of gender issues into national political, social and economic agenda and policies has been championed by international development and economic institutions. In developing HIV/Aids intervention policies, gender has also been mainstreamed, especially where epidemiological data show the disparity in infection rates between men and women, where women are seen as more susceptible to infection. The gendered approach to HIV/Aids appears to typecast women as the vulnerable and suffering face of HIV/Aids, while men, as ‘the other’, are generally regarded as the perpetuators and spreaders of the virus. While there is no doubt that women’s vulnerability in this milieu has been proven within known research evidence to exist, the neglect of institutional (social, cultural and economic and historical vulnerabilities of African men’s realities are sometimes overlooked. Recently, greater focus has shifted to curbing infection rates in men based on new scientific evidence that shows that risk of transmission in circumcised men is reduced. The article argues that such movement towards showing areas of men’s vulnerability as a focus in HIV/Aids policy interventions may have the potential to shift the observed burden that current HIV/Aids policy thrusts inadvertently place on African women. The article will put forward an argument for

Feline Immunodeficiency Virus in South America

2012-03-01

Full Text Available The rapid emergence of AIDS in humans during the period between 1980 and 2000 has led to extensive efforts to understand more fully similar etiologic agents of chronic and progressive acquired immunodeficiency disease in several mammalian species. Lentiviruses that have gene sequence homology with human immunodeficiency virus (HIV have been found in different species (including sheep, goats, horses, cattle, cats, and several Old World monkey species. Lentiviruses, comprising a genus of the Retroviridae family, cause persistent infection that can lead to varying degrees of morbidity and mortality depending on the virus and the host species involved. Feline immunodeficiency virus (FIV causes an immune system disease in domestic cats (Felis catus involving depletion of the CD4+ population of T lymphocytes, increased susceptibility to opportunistic infections, and sometimes death. Viruses related to domestic cat FIV occur also in a variety of nondomestic felids. This is a brief overview of the current state of knowledge of this large and ancient group of viruses (FIVs in South America.

Risk analysis. HIV / AIDS country profile: Senegal.

Science.gov (United States)

1996-12-01

Since the first acquired immunodeficiency syndrome (AIDS) case was confirmed in 1986, Senegal has conducted an aggressive prevention campaign. Senegal's National AIDS Committee has noted the contributions of poverty and migration to the spread of AIDS. By June 1994, 1297 AIDS cases had been reported and an estimated 500,000 people (1.4% of the population) were infected with human immunodeficiency virus (HIV)-1 and 2. The highest rate of HIV infection (14%) exists among commercial sex workers. At present, HIV/AIDS cases are concentrated in Dakar, Kaolack, the Matam region, and Ziguinchor; however, the growing importance of inter-regional trading is expected to spread HIV to the smaller towns and rural areas. Also salient is the recent devaluation by 50% of the CFA franc, which has reduced the public sector workforce and led many poor urban residents into commercial sex work. CFA devaluation has made Senegal attractive to tourists and business visitors--another factor responsible for growth of the legalized commercial sex industry. Although sex workers are instructed in condom use and tested annually for HIV, only 850 of the 2000 registered sex workers have reported for check-ups, and the majority of prostitutes are unregistered. Senegal's AIDS Plan for 1994-98 focuses on care of AIDS patients, pressures placed on family structures by HIV, and AIDS-related erosions in the status of women. Each health service region has its own local plan for AIDS/HIV and sexually transmitted diseases, supervised by a regional committee. Public education has involved outreach to religious leaders, promotion of affordable condoms, and distribution of over 75,000 leaflets to key target populations. About US $16 million of the $25,688,875-budget HIV/AIDS program for 1994-98 was pledged by external donors.

Association of TLR7 variants with AIDS-like disease and AIDS vaccine efficacy in rhesus macaques.

Directory of Open Access Journals (Sweden)

Roman A Siddiqui

Full Text Available In HIV infection, TLR7-triggered IFN-α production exerts a direct antiviral effect through the inhibition of viral replication, but may also be involved in immune pathogenesis leading to AIDS. TLR7 could also be an important mediator of vaccine efficacy. In this study, we analyzed polymorphisms in the X-linked TLR7 gene in the rhesus macaque model of AIDS. Upon resequencing of the TLR7 gene in 36 rhesus macaques of Indian origin, 12 polymorphic sites were detected. Next, we identified three tightly linked single nucleotide polymorphisms (SNP as being associated with survival time. Genotyping of 119 untreated, simian immunodeficiency virus (SIV-infected male rhesus macaques, including an 'MHC adjusted' subset, revealed that the three TLR7 SNPs are also significantly associated with set-point viral load. Surprisingly, this effect was not observed in 72 immunized SIV-infected male monkeys. We hypothesize (i that SNP c.13G>A in the leader peptide is causative for the observed genotype-phenotype association and that (ii the underlying mechanism is related to RNA secondary structure formation. Therefore, we investigated a fourth SNP (c.-17C>T, located 17 bp upstream of the ATG translation initiation codon, that is also potentially capable of influencing RNA structure. In c.13A carriers, neither set-point viral load nor survival time were related to the c.-17C>T genotype. In c.13G carriers, by contrast, the c.-17C allele was significantly associated with prolonged survival. Again, no such association was detected among immunized SIV-infected macaques. Our results highlight the dual role of TLR7 in immunodeficiency virus infection and vaccination and imply that it may be important to control human AIDS vaccine trials, not only for MHC genotype, but also for TLR7 genotype.

A serious challenge in cancer treatment is to reposition the activity of various already known drug candidates against cancer. There is a need to rewrite and systematically analyze the detailed mechanistic aspect of cellular networks to gain insight into the novel role played by various molecules. Most Human Immunodeficiency Virus infection-associated cancers are caused by oncogenic viruses like Human Papilloma Viruses and Epstein-Bar Virus. As the onset of AIDS-associated cancers marks the severity of AIDS, there might be possible interconnections between the targets and mechanism of both the diseases. We have explored the possibility of certain antiviral compounds to act against major AIDS-associated cancers: Kaposi's Sarcoma, Non-Hodgkin Lymphoma, and Cervical Cancer with the help of systems pharmacology approach that includes screening for targets and molecules through the construction of a series of drug-target and drug-target-diseases network. Two molecules (Calanolide A and Chaetochromin B) and the target "HRAS" were finally screened with the help of molecular docking and molecular dynamics simulation. The results provide novel antiviral molecules against HRAS target to treat AIDS defining cancers and an insight for understanding the pharmacological, therapeutic aspects of similar unexplored molecules against various cancers.

Whole transcriptome sequencing enables discovery and analysis of viruses in archived primary central nervous system lymphomas.

Directory of Open Access Journals (Sweden)

Christopher DeBoever

Full Text Available Primary central nervous system lymphomas (PCNSL have a dramatically increased prevalence among persons living with AIDS and are known to be associated with human Epstein Barr virus (EBV infection. Previous work suggests that in some cases, co-infection with other viruses may be important for PCNSL pathogenesis. Viral transcription in tumor samples can be measured using next generation transcriptome sequencing. We demonstrate the ability of transcriptome sequencing to identify viruses, characterize viral expression, and identify viral variants by sequencing four archived AIDS-related PCNSL tissue samples and analyzing raw sequencing reads. EBV was detected in all four PCNSL samples and cytomegalovirus (CMV, JC polyomavirus (JCV, and HIV were also discovered, consistent with clinical diagnoses. CMV was found to express three long non-coding RNAs recently reported as expressed during active infection. Single nucleotide variants were observed in each of the viruses observed and three indels were found in CMV. No viruses were found in several control tumor types including 32 diffuse large B-cell lymphoma samples. This study demonstrates the ability of next generation transcriptome sequencing to accurately identify viruses, including DNA viruses, in solid human cancer tissue samples.

Consultation on AIDS and the workplace.

Science.gov (United States)

1988-12-01

The 1988 Consultation on Acquired Immunodeficiency Syndrome (AIDS) and the Workplace, organized by the World Health Organization (WHO), addressed 3 issues: 1) risk factors associated with human immunodeficiency virus (HIV) infection in the workplace, 2) the response of businesses and workers to the AIDS epidemic, and 3) use of the workplace for AIDS education. There is no evidence to suggest that HIV can be transmitted by casual, person-to-person contact in the workplace. The central policy issue for businesses concerns protection of the human rights of workers with HIV infection. Most workers with HIV/AIDS want to continue working as long as they are able to, and they should be enabled to contribute their creativity and productivity in a supportive occupational setting. Consistent policies and procedures should be developed at national and enterprise levels before HIV-related questions arise in the workplace. Such policies should be communicated to all concerned, continually reviewed in the light of scientific and epidemiologic evidence, monitored for their successful implementation, and evaluated for their effectiveness. Pre-employment HIV/AIDS screening, whether for assessment of fitness to work or for insurance purposes, should not be required and raises serious concerns about discrimination. Moreover, there should be no obligation on the worker's part to inform his or her employer if HIV infection develops. Information and educational activities at the workplace are essential to create the climate of collective responsibility and mutual understanding required to protect individuals with HIV or AIDS from stigmatization and discrimination by co-workers, employers or clients, and unions.

HIV INFECTION AND AIDS: EPIDEMIOLOGY AND PREVENTION

Full Text Available Human Immune-deficiency Virus (HIV was first discovered in 1981 in the United States of America and the day of December 1, was announced as ?World AIDS Day? by WHO (World Health Organization. In Turkey, the first announcement of the people living with HIV was made in 1985. HIV/AIDS has killed more than 20 millions people and more than 16,000 people become newly infected each day since the first cases were diagnosed in 1981. It is estimated that 39.4 million people would have been infected with HIV at the end of 2004, with 4.9 million new cases that year. Sub-Saharan Africa is the worst-hit region, with 70 percent of all people living with HIV. In Africa alone, 10,000 people become infected each day. This year?s main theme is ?Women, Girls, HIV and AIDS,? which reflects a focus on how the effects of HIV/AIDS have significantly increased among women. Women now make up half of all people living with HIV worldwide with the number of 17,6 million. [TAF Prev Med Bull 2004; 3(11.000: 280-290

2013-01-01

Non-AIDS-defining cancers in HIV-infected patients in the highly active antiretroviral therapy era have increased. To our knowledge a comprehensive review of non-AIDS-related malignancies in New Orleans has not yet been conducted. Databases from main institutions in New Orleans were queried retrospectively for the years 2001 to 2011. The International Classification of Diseases, Ninth Revision codes were used to search for HIV infection and cancer comorbidity. A total of 16 patients were diagnosed with lung cancer (mean age 50 years) with 81% of the patients presenting with advanced stages. In all, 20 (mean age 47 years) were diagnosed with anal cancer, and 35% presented in late stages. In all, 14 patients (mean age 42 years) were diagnosed with Hodgkin Lymphoma, and 64% were diagnosed at late stage. A total of 5 women (mean age 44 years) were diagnosed with breast cancer with 40% of them presenting at late stage. Malignancies were diagnosed at late stages in the majority of the cases, presented with worse outcomes, and had higher recurrence rates. The role of HIV and other viruses (Epstein Barr virus, human papillomavirus) and the potential mechanisms or pathways of oncogene activation also need to be clarified.

Illicit drug users sustain the epidemics of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), hepatitis C (HCV), and sexually transmitted infections (STIs). Substance abuse treatment programs present a major intervention point in stemming these epidemics. As a part of the "Infections and Substance Abuse" study, established by the National Drug Abuse Treatment Clinical Trials Network, sponsored by National Institute on Drug Abuse, three surveys were developed; for treatment program administrators, for clinicians, and for state and District of Columbia health and substance abuse department administrators, capturing service availability, government mandates, funding, and other key elements related to the three infection groups. Treatment programs varied in corporate structure, source of revenue, patient census, and medical and non-medical staffing; medical services, counseling services, and staff education targeted HIV/AIDS more often than HCV or STIs. The results from this study have the potential to generate hypotheses for further health services research to inform public policy.

Cell lines derived from Kaposi sarcoma lesions of patients with AIDS (AIDS-KS cells) produce several cytokines, including an endothelial cell growth factor, interleukin 1β, and basic fibroblast growth factor. Since exposure to human immunodeficiency virus increases interleukin 6 (IL-6) production in monocytes and endothelial cells produce IL-6, the authors examined IL-6 expression and response in AIDS-KS cell lines and IL-6 expression in AIDS Kaposi sarcoma tissue. The AIDS-KS cell lines (N521J and EKS3) secreted large amounts of immunoreactive and biologically active IL-6. The authors found both IL-6 and IL-6 receptor (IL-6-R) RNA by slot blot hybridization analysis of AIDS-KS cells. The IL-6-R was functional, as [ 3 H]thymidine incorporation by AIDS-KS cells increased significantly after exposure to human recombinant IL-6 (hrIL-6) at >10 units/ml. When AIDS-KS cells (EKS3) were exposed to IL-6 antisense oligonucleotide, cellular proliferation decreased by nearly two-thirds, with a corresponding decrease in the production of IL-6. These results show that both IL-6 and IL-6-R are produced by AIDS-KS cells and that IL-6 is required for optimal AIDS-KS cell proliferation, and they suggest that IL-6 is an autocrine growth factor for AIDS-KS cells

[Rejecting or prioritizing life? The ambiguities of AIDS biopolitics in Uruguay].

Science.gov (United States)

Reihling, Hanspeter

2010-06-01

The biopolitics of aids in Uruguay could be seen between two big poles: the investment and the rejection of life. The productive mode can be expressed in the treatment of children who contracted HIV through mother to child transmission. For these children the infection in many cases becomes an asset until they reach adolescence. Except of some efforts of forced detention and mandatory testing, the public health system as well as NGOs show little interest in assisting adolescence infected or affected by HIV/aids. This is the result of a moral economy which marks people who are able to transmit the virus sexually or who have contracted it through sexual intercourse. Especially HIV positive mothers are seen as irresponsible and dangerous in contraposition to their "pure" offspring. However, this moral discourse hardly takes into account the larger social and economic context in which those mothers contracted the virus and as they faced Antiretroviral Therapy (ART). The life history of an adolescent boy will be told in order to reflect upon the modes of inclusion and exclusion of people living with HIV/aids since the beginning of the epidemic in Uruguay. Although the case is not representative, it identifies dynamics within the Uruguayan health system which are difficult to discern through conventional statistical methods.

HIV/AIDS is one of the worst pandemics in history. According to the World Health Organization, 26 million people have died since 1981 - 1.6 million in 2012 alone. The dramatic rise in HIV/AIDS mobilized a swift and impressive coordination among governmental, academic and private sector organizations to identify the virus and develop new treatments. Herein, we assess the arsenal of 28 new molecular entities (NMEs) targeting HIV/AIDS. These data demonstrate that the first approval of zidovudine presaged an expansion of the antiviral repertoire over the following years. Whereas the rate of HIV/AIDS NMEs is rapidly declining, so is the number of organizations developing NMEs. We speculate that decisions to abandon further research reflect, in part, growing costs and time required for development. Copyright © 2014 Elsevier Ltd. All rights reserved.

Determinants of HIV/AIDS in armed conflict populations.

Omare, Danvas; Kanekar, Amar

2011-03-01

More than 40 million people worldwide have been infected with human immunodeficiency virus (HIV) since it was first reported in 1981. Over 25 million of these have lost their lives to the disease. Most of the studies related to HIV/AIDS have been conducted in stable populations across the globe. Few of these studies have been devoted to displaced populations, particularly those in areas of conflict. Displaced populations that are forced to leave their homes in most cases find themselves in unfamiliar territories, often poor and hungry. Many of them become refugees and internally displaced people (IDPs). The objective of this review was to address a number of different social determinants of HIV/AIDS in displaced populations in areas of conflict. A comprehensive review of peer reviewed literature published in English between 1990 and 2010 obtained through an open search of PUBMED database using key words such as HIV and war , HIV/AIDS and conflict , AIDS and security was conducted. Twelve different studies that looked at the implications of HIV/AIDS in conflict or displaced populations were retrieved. The review revealed that there were various factors influencing conflict and HIV/AIDS such as forced population displacement, breakdown of traditional sexual norms, lack of health infrastructure, and poverty and powerlessness of women and children. Social determinants of increased HIV/AIDS prevalence in displaced populations are scarcity of food, poverty, insecurity of displaced populations and gender power differentials.

Full Text Available More than 40 million people worldwide have been infected with human immunodeficiency virus (HIV since it was first reported in 1981. Over 25 million of these have lost their lives to the disease. Most of the studies related to HIV/AIDS have been conducted in stable populations across the globe. Few of these studies have been devoted to displaced populations, particularly those in areas of conflict. Displaced populations that are forced to leave their homes in most cases find themselves in unfamiliar territories, often poor and hungry. Many of them become refugees and internally displaced people (IDPs. The objective of this review was to address a number of different social determinants of HIV/AIDS in displaced populations in areas of conflict. A comprehensive review of peer reviewed literature published in English between 1990 and 2010 obtained through an open search of PUBMED database using key words such as “HIV and war”, “HIV/AIDS and conflict”, “AIDS and security” was conducted. Twelve different studies that looked at the implications of HIV/AIDS in conflict or displaced populations were retrieved.

The spectrum of pathology affecting the central nervous system (CNS) in patients suffering from acquired immunodeficiency syndrome (AIDS) includes not only the human immunodeficiency virus (HIV) infection itself but also opportunistic infections and tumors secondary to AIDS. Despite progress in antiretroviral therapy and the subsequent decrease in the incidence of associated diseases, opportunistic infections and tumors secondary to the HIV infection continue to be the limiting factor in terms of survival with AIDS. Therefore, the therapeutic aim is permanent antiretroviral therapy as well as early diagnosis and treatment of opportunistic infections. Magnetic resonance imaging is often the diagnostic method of choice in suspected CNS pathology of HIV patients. In the following, the typical clinical and radiological features of several AIDS-related pathologies are presented and discussed. (orig.)

There is very little known about the prevalence and distribution of respiratory viruses, other than influenza, in international air travellers and whether symptom screening would aid in the prediction of which travellers are more likely to be infected with specific respiratory viruses. In this study, we investigate whether, the use of a respiratory symptom screening tool at the border would aid in predicting which travellers are more likely to be infected with specific respiratory viruses. Data were collected from travellers arriving at Christchurch International Airport, New Zealand, during the winter 2008, via a symptom questionnaire, temperature testing, and respiratory sampling. Respiratory viruses were detected in 342 (26.0%) of 1313 samples obtained from 2714 symptomatic travellers. The most frequently identified viruses were rhinoviruses (128), enteroviruses (77) and influenza B (48). The most frequently reported symptoms were stuffy or runny nose (60%), cough (47%), sore throat (27%) and sneezing (24%). Influenza B infections were associated with the highest number of symptoms (mean of 3.4) followed by rhinoviruses (mean of 2.2) and enteroviruses (mean of 1.9). The positive predictive value (PPV) of any symptom for any respiratory virus infection was low at 26%. The high prevalence of respiratory virus infections caused by viruses other than influenza in this study, many with overlapping symptotology to influenza, has important implications for any screening strategies for the prediction of influenza in airline travellers.

Magnetic resonance imaging is the most sensitive and the most specific technique for the study of the neurological complications of AIDS. The analysis of the images must be aimed at recognizing the specific lesions produced by the human immunodeficiency virus (HIV), in order to identify the opportunistic lesions, which are often multiple. For each major opportunistic disease, a number of arguments likely to guide the treatment can be pointed out [fr

Pharmacological inhibition of feline immunodeficiency virus (FIV).

Mohammadi, Hakimeh; Bienzle, Dorothee

2012-05-01

Feline immunodeficiency virus (FIV) is a member of the retroviridae family of viruses and causes an acquired immunodeficiency syndrome (AIDS) in domestic and non-domestic cats worldwide. Genome organization of FIV and clinical characteristics of the disease caused by the virus are similar to those of human immunodeficiency virus (HIV). Both viruses infect T lymphocytes, monocytes and macrophages, and their replication cycle in infected cells is analogous. Due to marked similarity in genomic organization, virus structure, virus replication and disease pathogenesis of FIV and HIV, infection of cats with FIV is a useful tool to study and develop novel drugs and vaccines for HIV. Anti-retroviral drugs studied extensively in HIV infection have targeted different steps of the virus replication cycle: (1) inhibition of virus entry into susceptible cells at the level of attachment to host cell surface receptors and co-receptors; (2) inhibition of fusion of the virus membrane with the cell membrane; (3) blockade of reverse transcription of viral genomic RNA; (4) interruption of nuclear translocation and viral DNA integration into host genomes; (5) prevention of viral transcript processing and nuclear export; and (6) inhibition of virion assembly and maturation. Despite much success of anti-retroviral therapy slowing disease progression in people, similar therapy has not been thoroughly investigated in cats. In this article we review current pharmacological approaches and novel targets for anti-lentiviral therapy, and critically assess potentially suitable applications against FIV infection in cats.

Full Text Available The epidemic of human immunodeficiency virus / acquired immunodeficiency syndrome (HIV / AIDS in the elderly in Brazil has emerged a public health problem. When we refer to aging and AIDS we must consider the sexuality of older people. Research aimed to characterize and identify through the viewpoint of senior knowledge and sentiment against the HIV / AIDS. The methodology of the study was descriptive and quantitative descriptiveanalysis. The results of this study have said that older people have knowledge about HIV / AIDS. Only 22.2% use condoms. We conclude that prevention campaigns are not reaching the elderly. For we know that many seniors have active sex life, with more than one partner. Prevention campaigns and actions of the nursing staff should pay special attention to this fact and increase the information, so that older people can understand and adhere to the means of prevention of this disease.

Abstract This study uses Goffman's [1963. Stigma: Notes on the Management of Spoiled Identity, New Jersey, Prentice-Hall] theory of stigma as an intellectual scaffold to help understand the social meaning of HIV/AIDS stigma from People Living with HIV/AIDS. The study adopts a qualitative approach because of its appropriateness for unravelling subjective phenomena such as the experiences of HIV/AIDS stigma. In-depth interviews were conducted with 10 HIV-positive employees of a retailing company located in the Western Cape province of South Africa who volunteered to participate in the study. The participants with the discreditable stigma internalised society's prejudice towards those living with the virus. As a result, the participants relied on self-isolation and social withdrawal to cope with enacted stigma. Managing information about one's status and deciding whether, who, when, etc., to tell are crucial questions. The participants feared being devalued by family, friends, co-workers and the community. In concurrence with Goffman [1963. Stigma: Notes on the Management of Spoiled Identity, New Jersey, Prentice-Hall] the HIV/AIDS stigma is seen as about relationships. PMID:24980478

Defining Moments in MMWR History: The AIDS Epidemic, Pneumocystis Pneumonia --- Los Angeles 1981

Centers for Disease Control (CDC) Podcasts

On June 5, 1981, MMWR published a report of Pneumocystis pneumonia in five previously healthy young gay men in Los Angeles, California. This report was later acknowledged as the first published account of what would become known as human immunodeficiency virus, or HIV, and acquired immunodeficiency syndrome, or AIDS. It was the first of many MMWR reports that led to a better understanding of this new condition. In this podcast, Dr. Harold Jaffe recalls CDC's investigation and response to the AIDS Epidemic.

Vaccination with exogenous antigens such as recombinant viral proteins, immunodeficiency virus-derived whole inactivated virus particles, or virus-like particles (VLP) has generally failed to provide sufficient protection in animal models for AIDS. Pseudotyping VLPs with the vesicular stomatitis virus G protein (VSV-G), which is known to mediate entry into dendritic cells, might allow more efficient stimulation of immune responses. Therefore, we pseudotyped noninfectious immunodeficiency virus-like particles with VSV-G and carried out a preliminary screen of their immunogenicity and vaccination efficacy. Incorporation of VSV-G into HIV-1 VLPs led to hundred-fold higher antibody titers to HIV-1 Gag and enhancement of T cell responses in mice. Repeated vaccination of rhesus monkeys for 65 weeks with VSV-G pseudotyped simian immunodeficiency virus (SIV)-like particles (VLP[G]) provided initial evidence for efficient suppression of viral load after mucosal challenge with the SIVmac239 virus. Challenge of monkeys after a 28 week vaccination regimen with VLP[G] led to a reduction in peak viremia, but persistent suppression of viral load was not achieved. Due to limitations in the number of animals available for this study, improved efficacy of VSV-G pseudotyped VLPs in nonhuman primates could not be demonstrated. However, mouse experiments revealed that pseudotyping of VLPs with fusion-competent VSV-G clearly improves their immunogenicity. Additional strategies, particularly adjuvants, should be considered to provide greater protection against a challenge with pathogenic immunodeficiency virus

Human immunodeficiency virus contains an epitope immunoreactive with thymosin α1 and the 30-amino acid synthetic p17 group-specific antigen peptide HGP-30

The authors have reported that an antiserum prepared against thymosin α 1 [which shares a region of homology with the p17 protein of the acquired immunodeficiency syndrome (AIDS)-associated human immunodeficiency virus] effectively neutralized the AIDs virus and prevented its replication in H9 cells. Using HPLC and immunoblot analysis, they have identified from a clone B, type III human T-lymphotropic virus (HTLV-IIIB) extracts a protein with a molecular weight of 17,000 that is immunoreactive with thymosin α 1 . In contrast, no immunoreactivity was found in retroviral extracts from a number of nonhuman species including feline, bovine, simian, gibbon, and murine retroviruses. Heterologous antiserum prepared against a 30-amino acid synthetic peptide analogue (HGP-30) does not cross-react with thymosin α 1 but does react specifically with the p17 protein of the AIDS virus in a manner identical to that seen with an HTLV-IIIB p17-specific monoclonal antibody. The demonstration that this synthetic analogue is immunogenic and that antibodies to HGP-30 cross-react not only with synthetic peptide but also with the HTLV-IIIB p17 viral protein provides an additional, and potentially more specific, candidate for development of a synthetic peptide vaccine for AIDS. In addition, the p17 synthetic peptide (HGP-3) may prove to be useful in a diagnostic assay for the detection of AIDS virus infection in seronegative individuals

Human immunodeficiency virus endocrinopathy

Uma Sinha

2011-01-01

Full Text Available Human immunodeficiency virus (HIV endocrinopathy encompasses a broad spectrum of disorders. Almost all the endocrine organs are virtually affected by HIV infection. HIV can directly alter glandular function. More commonly secondary endocrine dysfunction occurs due to opportunistic infections and neoplasms in immunocompromised state. The complex interaction between HIV infection and endocrine system may be manifested as subtle biochemical and hormonal perturbation to overt glandular failure. Antiretroviral therapy as well as other essential medications often result in adverse endocrinal consequences. Apart from adrenal insufficiency, hypogonadism, diabetes and bone loss, AIDS wasting syndrome and HIV lipodystrophy need special reference. Endocrinal evaluation should proceed as in other patients with suspected endocrine dysfunction. Available treatment options have been shown to improve quality of life and long-term mortality in AIDS patients.

HIV/AIDS: Knowledge, attitudes and practices among adolescents in Nimule, South Sudan

Full Text Available Background: HIV is an infectious virus commonly transmitted through body fluids mostly semen and blood. It causes a serious and non-curable disease with grave consequences especially in sub-Saharan Africa. In South Sudan the prevalence rate of HIV was estimated at 2.6% in 2016. The treatment options are scarce and educational programs limited. This is of great concern since limited knowledge and awareness of HIV is a major risk factor particularly, among young people. Method: A cross-sectional survey using self-administered questionnaires among adolescents was carried out in November 2016. Results: Sixty-five students participated in the study. In general they had good knowledge about HIV/AIDS with the majority having heard of HIV. Majority stated that HIV spreads through sex (82%, blood transfusion (95%, and from mother to child during pregnancy and delivery (66%. Several misconceptions were present with 43% responding that HIV can be transmitted through mosquito bites and 18% stating that the virus can be spread through shaking hands, hugging and living in the same house. Conclusion: Though the respondents showed fair knowledge about HIV/AIDS, there are still some areas in which they lack knowledge especially regarding spread of the disease and practice. More information about HIV/AIDS and sexual education should be made available.

Human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS) is pandemic. It has affected nearly 60 million people since the detection of the disease in 1981 to date. In this paper basic deterministic HIV/AIDS model with mass action incidence function are developed. Stability analysis is carried out. And the disease free equilibrium of the basic model was found to be locally asymptotically stable whenever the threshold parameter (RO) value is less than one, and unstable otherwise. The model is extended by introducing two optimal control strategies namely, CD4 counts and treatment for the infective using optimal control theory. Numerical simulation was carried out in order to illustrate the analytic results.

Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the central nervous system caused by the JC virus (JCV), a human papovavirus. PML is a relatively rare disease seen predominantly in immunocompromised individuals and is a frequent complication observed in AIDS patients. The significantly higher incidence of PML in AIDS patients than in other immunosuppressive disorders has suggested that the presence of human immunodeficiency virus type 1 (HIV-1) in the brain may directly or indirectly contribute to the pathogenesis of this disease. In the present study the authors have examined the expression of the JCV genome in both glial and non-glial cells in the presence of HIV-1 regulatory proteins. They find that the HIV-1-encoded trans-regulatory protein tat increases the basal activity of the JCV late promoter, JCV L , in glial cells. They conclude that the presence of the HIV-1-encoded tat protein may positively affect the JCV lytic cycle in glial cells by stimulating JCV gene expression. The results suggest a mechanism for the relatively high incidence of PML in AIDS patients than in other immunosuppressive disorders. Furthermore, the findings indicate that the HIV-1 regulatory protein tat may stimulate other viral and perhaps cellular promoters, in addition to its own

Full Text Available BACKGROUND: Although Chinese-origin Rhesus macaques (Ch RhMs infected with simian immunodeficiency virus (SIV have been used for many years to evaluate the efficacy of AIDS vaccines and therapeutics, the bio-clinical variability of such a nonhuman primate AIDS model was so far not established. METHODOLOGY/PRINCIPAL FINDINGS: By randomizing 150 (78 male and 72 female Ch RhMs with diverse MHC class I alleles into 3 groups (50 animals per group challenged with intrarectal (i.r. SIVmac239, intravenous (i.v. SIVmac239, or i.v. SIVmac251, we evaluated variability in bio-clinical endpoints for 118 weeks. All SIV-challenged Ch RhMs became seropositive for SIV during 1-2 weeks. Plasma viral load (VL peaked at weeks 1-2 and then declined to set-point levels as from week 5. The set-point VL was 30 fold higher in SIVmac239 (i.r. or i.v.-infected than in SIVmac251 (i.v.-infected animals. This difference in plasma VL increased overtime (>100 fold as from week 68. The rates of progression to AIDS or death were more rapid in SIVmac239 (i.r. or i.v.-infected than in SIVmac251 (i.v.-infected animals. No significant difference in bio-clinical endpoints was observed in animals challenged with i.r. or i.v. SIVmac239. The variability (standard deviation in peak/set-point VL was nearly one-half lower in animals infected with SIVmac239 (i.r. or i.v. than in those infected with SIVmac251 (i.v., allowing that the same treatment-related difference can be detected with one-half fewer animals using SIVmac239 than using SIVmac251. CONCLUSION/SIGNIFICANCE: These results provide solid estimates of variability in bio-clinical endpoints needed when designing studies using the Ch RhM SIV model and contribute to the improving quality and standardization of preclinical studies.

The beginning of the second century of research in the field of virology (the first virus was discovered in 1898) was marked by its amalgamation with bioinformatics, resulting in the birth of a new domain--viroinformatics. The availability of more than 100 Web servers and databases embracing all or specific viruses (for example, dengue virus, influenza virus, hepatitis virus, human immunodeficiency virus [HIV], hemorrhagic fever virus [HFV], human papillomavirus [HPV], West Nile virus, etc.) as well as distinct applications (comparative/diversity analysis, viral recombination, small interfering RNA [siRNA]/short hairpin RNA [shRNA]/microRNA [miRNA] studies, RNA folding, protein-protein interaction, structural analysis, and phylotyping and genotyping) will definitely aid the development of effective drugs and vaccines. However, information about their access and utility is not available at any single source or on any single platform. Therefore, a compendium of various computational tools and resources dedicated specifically to virology is presented in this article. Copyright © 2015, American Society for Microbiology.

The long-term effectiveness of human immunodeficiency virus (HIV) treatments containing integrase inhibitors is unknown. We use observational data from the Centers for AIDS Research Network of Integrated Clinical Systems and the Centers for Disease Control and Prevention to estimate 4-year risk of AIDS and all-cause mortality among 415 patients starting a raltegravir regimen compared to 2646 starting an efavirenz regimen (both regimens include emtricitabine and tenofovir disoproxil fumarate). We account for confounding and selection bias as well as generalizability by standardization for measured variables, and present both observational intent-to-treat and per-protocol estimates. At treatment initiation, 12% of patients were female, 36% black, 13% Hispanic; median age was 37 years, CD4 count 321 cells/µL, and viral load 4.5 log10 copies/mL. Two hundred thirty-five patients incurred an AIDS-defining illness or died, and 741 patients left follow-up. After accounting for measured differences, the 4-year risk was similar among those starting both regimens (ie, intent-to treat hazard ratio [HR], 0.96 [95% confidence interval {CI}, .63-1.45]; risk difference, -0.9 [95% CI, -4.5 to 2.7]), as well as among those remaining on regimens (ie, per-protocol HR, 0.95 [95% CI, .59-1.54]; risk difference, -0.5 [95% CI, -3.8 to 2.9]). Raltegravir and efavirenz-based initial antiretroviral therapy have similar 4-year clinical effects. Vigilance regarding longer-term comparative effectiveness of HIV regimens using observational data is needed because large-scale experimental data are not forthcoming. © The Author 2017.

[GESIDA/National AIDS Plan: Consensus document on antiretroviral therapy in adults infected by the human immunodeficiency virus (Updated January 2015)].

Science.gov (United States)

2015-10-01

This consensus document is an update of combined antiretroviral therapy (cART) guidelines and recommendations for HIV-1 infected adult patients. To formulate these recommendations, a panel composed of members of the AIDS Study Group and the AIDS National Plan (GeSIDA/Plan Nacional sobre el Sida) reviewed the efficacy and safety advances in clinical trials, and cohort and pharmacokinetic studies published in medical journals (PubMed and Embase) or presented in medical scientific meetings. The strength of the recommendations, and the evidence that supports them, are based on modified criteria of the Infectious Diseases Society of America. In this update, cART is recommended for all patients infected by type 1 human immunodeficiency virus (HIV-1). The strength and level of the recommendation depends on the CD4+T-lymphocyte count, the presence of opportunistic diseases or comorbid conditions, age, and prevention of transmission of HIV. The objective of cART is to achieve an undetectable plasma viral load. Initial cART should always comprise a combination of 3 drugs, including 2 nucleoside reverse transcriptase inhibitors, and a third drug from a different family. Three out of the ten recommended regimes are regarded as preferential (all of them with an integrase inhibitor as the third drug), and the other seven (based on a non-nucleoside reverse transcriptase inhibitor, a ritonavir-boosted protease inhibitor, or an integrase inhibitor) as alternatives. This update presents the causes and criteria for switching cART in patients with undetectable plasma viral load, and in cases of virological failure where rescue cART should comprise 3 (or at least 2) drugs that are fully active against the virus. An update is also provided for the specific criteria for cART in special situations (acute infection, HIV-2 infection, and pregnancy) and with comorbid conditions (tuberculosis or other opportunistic infections, kidney disease, liver disease, and cancer). These new guidelines

Full Text Available Background & Objective: The immune system of Patients with Acquired Immune Deficiency Syndrome (AIDS is weekend because of Human immunodeficiency virus (HIV infection, and they become vulnerable to several opportunistic and non-opportunistic pathogens and different carcinomas. IV drug abuse, sexual contact, occupational transmission, blood transfusion and maternal-fetal transmission are well known transmission routes for HIV infection. This study was under taken to investigate the prevalence of HIV transmission routs in the HIV infected population of Sirjan, and their knowledge about the disease, in order to plan better preventive strategies. Materials & Methods: A cross sectional study was planned. During a 6-month period in 2010, all of the HIV infected people in Sirjan (old and new cases who had a file at the consultation center for high risk behavior, completed a valid and reliable questionnaire. Results: The definite route of transmission was not clear in any of the patients because they had more than one suspicious route. Injected drug abusers were the most common (88.4% followed by those who got tattoos (79.1%, invasive therapeutic procedures, dentistry, surgery and endoscopy (56.1%, high risk sexual behavior (62.8%, bloodletting (9.3%, injuries in the barbershop (9.3% and blood transfusion (2.3%. Conclusion: All of the HIV infected cases in Sirjan were involved with several high risk behaviors, but the major route of transmission, similar to other parts of the country was injected drug abuse. Educational programs for prevention of AIDS should be followed seriously and special attention should be paid to groups with multiple high risk behaviors.

Full Text Available Feline immunodeficiency virus (FIV is a member of the retroviridae family of viruses and causes an acquired immunodeficiency syndrome (AIDS in domestic and non-domestic cats worldwide. Genome organization of FIV and clinical characteristics of the disease caused by the virus are similar to those of human immunodeficiency virus (HIV. Both viruses infect T lymphocytes, monocytes and macrophages, and their replication cycle in infected cells is analogous. Due to marked similarity in genomic organization, virus structure, virus replication and disease pathogenesis of FIV and HIV, infection of cats with FIV is a useful tool to study and develop novel drugs and vaccines for HIV. Anti-retroviral drugs studied extensively in HIV infection have targeted different steps of the virus replication cycle: (1 inhibition of virus entry into susceptible cells at the level of attachment to host cell surface receptors and co-receptors; (2 inhibition of fusion of the virus membrane with the cell membrane; (3 blockade of reverse transcription of viral genomic RNA; (4 interruption of nuclear translocation and viral DNA integration into host genomes; (5 prevention of viral transcript processing and nuclear export; and (6 inhibition of virion assembly and maturation. Despite much success of anti-retroviral therapy slowing disease progression in people, similar therapy has not been thoroughly investigated in cats. In this article we review current pharmacological approaches and novel targets for anti-lentiviral therapy, and critically assess potentially suitable applications against FIV infection in cats.

UNICEF estimates that the streets are now the home of some 5 million African children aged 7-15 who are victims of rapid population growth and urbanization as well as the disintegration of traditional family structure. These children, deprived of a home and of all parental control, are potentially very vulnerable to the threat of AIDS. Prostitution, which is almost institutionalized in the most impoverished urban areas, represents for young girls the most immediate means of survival and occasionally even of helping their families. Male prostitution is highly tabu and marginal in sub-Saharan Africa, and is only slightly developed around the tourist hotels. Homeless children are somewhat protected against contamination through the blood by their lack of access to health care. Intravenous drugs are rare in Africa, and drug use is at most an indirect risk factor for AIDS to the extent that in increases the need for money and weakens the immune system. The frequency of sexually transmitted diseases, deplorable hygienic conditions, and poor general health of homeless children increase their risk of contracting the virus. Many homeless children do not even know of the existence of condoms and in any event condoms are usually inaccessible or too costly for them. Homeless children, like the general population, have false ideas about AIDS that discourage self-protective behaviors. In addition they are cut off from the activities of existing prevention programs. In a context of permanent daily insecurity, AIDS appears as just 1 more menace among others. According to an anthropologist working with the UNESCO program to help homeless children, the only way of making such children aware of the threat of AIDS in the large African cities will be to increase the number of prevention programs targeted at them. At the same time, the children need to be educated and taught an income-generating skill; in short, they need to be given a reason to believe in the future.

The AIDS pandemic continues to present us with unique scientific and public health challenges. Although the development of effective antiretroviral therapy has been a major triumph, the emergence of drug resistance requires active management of treatment regimens and the continued development of new antiretroviral drugs. Moreover, despite nearly 30 years of intensive investigation, we still lack the basic scientific knowledge necessary to produce a safe and effective vaccine against HIV-1. Animal models offer obvious advantages in the study of HIV/AIDS, allowing for a more invasive investigation of the disease and for preclinical testing of drugs and vaccines. Advances in humanized mouse models, non-human primate immunogenetics and recombinant challenge viruses have greatly increased the number and sophistication of available mouse and simian models. Understanding the advantages and limitations of each of these models is essential for the design of animal studies to guide the development of vaccines and antiretroviral therapies for the prevention and treatment of HIV-1 infection.

2014-01-01

A wide range of influenza A viruses of pigs and birds have infected humans in the last decade, sometimes with severe clinical consequences. Each of these so-called zoonotic infections provides an opportunity for virus adaptation to the new host. Fortunately, most of these human infections do not yield viruses with the ability of sustained human-to-human transmission. However, animal influenza viruses have acquired the ability of sustained transmission between humans to cause pandemics on rare occasions in the past, and therefore, influenza virus zoonoses continue to represent threats to public health. Numerous recent studies have shed new light on the mechanisms of adaptation and transmission of avian and swine influenza A viruses in mammals. In particular, several studies provided insights into the genetic and phenotypic traits of influenza A viruses that may determine airborne transmission. Here, we summarize recent studies on molecular determinants of virulence and adaptation of animal influenza A virus and discuss the phenotypic traits associated with airborne transmission of newly emerging influenza A viruses. Increased understanding of the determinants and mechanisms of virulence and transmission may aid in assessing the risks posed by animal influenza viruses to human health, and preparedness for such risks.

We have compared the variable region 3 sequences from 10 human immunodeficiency virus type 1 (HIV-1)-infected infants to virus sequences from the corresponding mothers. The sequences were derived from DNA of uncultured peripheral blood mononuclear cells (PBMC), DNA of cultured PBMC, and RNA from serum collected at or shortly after delivery. The infected infants, in contrast to the mothers, harbored homogeneous virus populations. Comparison of sequences from the children and clones derived from DNA of the corresponding mothers showed that the transmitted virus represented either a minor or a major virus population of the mother. In contrast to an earlier study, we found no evidence of selection of minor virus variants during transmission. Furthermore, the transmitted virus variant did not show any characteristic molecular features. In some cases the transmitted virus was more related to the virus RNA population of the mother and in other cases it was more related to the virus DNA population. This suggests that either cell-free or cell-associated virus may be transmitted. These data will help AIDS researchers to understand the mechanism of transmission and to plan strategies for prevention of transmission. PMID:8446584

The first confirmed case of HIV/AIDS in the Caribbean was reported in 1982, however a recent report by UNAIDS shows that the epidemic has risen to over 250,000 persons living with the virus with the highest prevalence rates shown to be in the Dominican Republic and Haiti. Various factors ranging from commercial sex trading to unsafe injection employed for drug abuse have been identified to play a contributing role in this increase. Also, the role and impact of tourism on the spread of HIV infection has been reported. Due to concerns shown by countries and territories who are dependent on tourism and that they rank amongst the most highly affected by HIV/AIDS in the region, this paper endeavours to examine the impact of HIV/AIDS and the contributing role of tourism to HIV/AIDS epidemic in the Caribbean.

The acquired immunodeficiency syndrome (AIDS) epidemic represents a modern-day plague that has not only resulted in a tragic loss of people from a wide spectrum of society but has reshaped our viewpoints regarding health care, the treatment of infectious diseases, and social issues regarding sexual behavior. There is little doubt now that the cause of the disease AIDS is a virus known as the human immunodeficiency virus (HIV). The HIV virus is a member of a large family of viruses termed retroviruses, which have as a hallmark the capacity to convert their RNA genome into a DNA form that then undergoes a process of integration into the host cell chromosome, followed by the expression of the viral genome and translation of viral proteins in the infected cell. This review describes the organization of the HIV-1 viral genome, the expression of viral proteins, as well as the functions of the accessory viral proteins in HIV replication. The replication of the viral genome is divided into two phases, the early phase and the late phase. The early phase consists of the interaction of the virus with the cell surface receptor (CD4 molecule in most cases), the uncoating and conversion of the viral RNA genome into a DNA form, and the integration into the host cell chromosome. The late phase consists of the expression of the viral proteins from the integrated viral genome, the translation of viral proteins, and the assembly and release of the virus. Points in the HIV-1 life cycle that are targets for therapeutic intervention are also discussed.

A moment in time: AIDS and business.

Bloom, D E; Rosenfield, A

Business has transformed the planet. But this gives it new responsibilities. People now expect business leaders to lead--and not just respond when things go wrong. HIV/AIDS is a global problem, with over 16.3 million people now thought to have died of the disease (Global Summary of HIV/AIDS Epidemic, UNAIDS, December 1999). Without action now, the pandemic will worsen, health services will come under relentless pressure and the number of people dying will increase exponentially. So why should business sit up and take notice? First: money. AIDS is slowly strangling many businesses and economies--and in a global market, everyone eventually suffers. Without profit, there is no business--so the business community needs to act to protect its bottom line. Second: people. Over 80% of those dying are in their 20s, 30s, and 40s. Businesses are losing workers and customers, and human networks that have taken decades to build. Third: imagination. Business is inventive, creative and fast-moving. It has the opportunity to use these strengths for the benefit of the wider community. It's time to pit business ideas (and some money, too) against the threat of AIDS. The course of the AIDS epidemic is not inevitable. The world's businesses have the skills and intensity to make a measurable difference, especially if they find public sector and NGO partners with whom they share a vision. A focused, coordinated, results-driven effort will hit AIDS hard. The HIV virus moves fast (and is mutating all the time). Business has the opportunity to make a difference. It must grasp this opportunity. And grasp if fast.

To evaluate the level of knowledge, attitudes, and risk perceptions of University Sains Malaysia final-year pharmacy students regarding human immunodeficiency virus (HIV) and acquired immunity deficiency syndrome (AIDS). A cross-sectional study among pharmacy students. Data were analyzed with Chi-square to find difference at p value AIDS patients. Students recommended HIV testing for health care professionals (69.4%) and patients (75.9%) before surgical procedures. Students knew little about Post Exposure Prophylaxis (18.5%) or about the time for HIV to develop into AIDS (57.4%). About 40% of students were unaware of the inability of antivirals to treat HIV/AIDS. Students had low awareness for opportunistic infections (18.5%), and low agreement on competency to treat and counsel HIV patients (12.9%). The study highlighted students' misconceptions, negative attitudes, and risk perceptions towards HIV/AIDS.

Evidence for a Euro-American origin of human immunodeficiency virus (HIV).

Recent reports of the nonspecificity of the enzyme-linked immunosorbent assay (ELISA) test in African populations, significant genomic differences between simian T-cell lymphotropic virus and human immunodeficiency virus (HIV), and the early appearance of clinical acquired immunodeficiency syndroME (AIDS) in the US and Europe are powerful arguments against the assumption that AIDS originated in Africa. The authors postulate that HIV infection has been endemic in the Euro-American population at least since the beginning of the 20th century and that sociocultural changes led to the introduction of the virus into Africa. A search of the literature reveals 28 cases of disseminated Kaposi's sarcoma in the pre-epidemic 1902-66 period. In none of these cases are notations made on intravenous drug abuse, homosexuality, or other risk factors for AIDS. The majority of cases involved men, however. It is pointed out that, in a population where the incidence of a virus such as HIV is low, the number of sexual partners is limited, and intravenous drug abuse is nonexistent, an infection with as long a latency period as HIV may not only be expressed sporadically, but would probably not be recognized as a transmissible infection. On the other hand, the significant changes in these social factors that occurred as a result of the sexual revolution of the late 1960s and early 1970s would be expected to increase the spread of infection and clinical disease so that recognition would be achieved. During the past decade, there have been marked increases in the number of sexually transmitted infections in the homosexual male population. The efficiency of anal intercourse as a mode of transmission probably accounts for the fact that HIV infection first expressed itself in this population.

Hendra virus is a highly pathogenic zoonotic paramyxovirus in the genus Henipavirus. Thirty-nine outbreaks of Hendra virus have been reported since its initial identification in Queensland, Australia, resulting in seven human infections and four fatalities. Little is known about cellular host factors impacting Hendra virus replication. In this work, we demonstrate that Hendra virus makes use of a microRNA (miRNA) designated miR-146a, an NF-κB-responsive miRNA upregulated by several innate immune ligands, to favor its replication. miR-146a is elevated in the blood of ferrets and horses infected with Hendra virus and is upregulated by Hendra virus in human cells in vitro. Blocking miR-146a reduces Hendra virus replication in vitro, suggesting a role for this miRNA in Hendra virus replication. In silico analysis of miR-146a targets identified ring finger protein (RNF)11, a member of the A20 ubiquitin editing complex that negatively regulates NF-κB activity, as a novel component of Hendra virus replication. RNA interference-mediated silencing of RNF11 promotes Hendra virus replication in vitro, suggesting that increased NF-κB activity aids Hendra virus replication. Furthermore, overexpression of the IκB superrepressor inhibits Hendra virus replication. These studies are the first to demonstrate a host miRNA response to Hendra virus infection and suggest an important role for host miRNAs in Hendra virus disease. PMID:23345523

An ongoing tragedy: the acquired immune deficiency syndrome (AIDS).

Desai, B T

1989-01-01

The AIDS epidemic has, to date, had only a minimal impact in India; however, given the low health status of the population and the lack of adequate health care facilities, the emergence of AIDS on a wider scale would be devastating. India's human immunodeficiency virus (HIV) seropositivity rate now stands at about 2-3/1000 people tested. In what is suspected to be a racially motivated move, the Government of India has embarked on testing all foreign students (most of whom are from Africa) for HIV and is returning all those who test seropositive to their countries of origin. Of concern is the steady increase in HIV infection in professional blood donors (1.5/1000 in late 1988). Mandatory screening of donated blood is prohibitively expensive in India, and none of the 9 companies that manufacture blood products in India test their donors for HIV infection. Another concern is the finding that 1 of every 6 prostitutes in Bombay is infected with HIV. The response of the Indian Government to the AIDS threat has tended to be punitive toward AIDS victims rather than based on a sound preventive strategy. For example, the 1989 AIDS Prevention Bill forces individuals who are infected with HIV to reveal their past sexual partners, empowers authorities to hospitalize AIDS victims and drug addicts, and contains no provisions to protect the human and civil rights of AIDS victims. The mass media have treated AIDS in a sensationalized manner rather than presenting scientific information about the prevention and transmission of the disease. It is essential that the Government of India--and all world governments--realize that punitive measures will do little to reduce the spread of AIDS. Needed, instead, is a global prevention and control effort based on generosity and compassion.

The 4 dengue serotypes (DENV) are mosquito-borne pathogens that are associated with severe hemorrhagic disease. DENV particles have a lipid bilayer envelope that anchors two membrane glycoproteins prM and E. Two E-protein monomers form head-to-tail homodimers and three E-dimers align to form "rafts" that cover the viral surface. Some human antibodies that strongly neutralize DENV bind to quaternary structure epitopes displayed on E protein dimers or higher order structures forming the infectious virus. Expression of prM and E in cell culture leads to the formation of DENV virus-like particles (VLPs) which are smaller than wildtype virus particles and replication defective due to the absence of a viral genome. There is no data available that describes the antigenic landscape on the surface of flavivirus VLPs in comparison to the better studied infectious virion. A large panel of well characterized antibodies that recognize epitope of ranging complexity were used in biochemical analytics to obtain a comparative antigenic surface view of VLPs in respect to virus particles. DENV patient serum depletions were performed the show the potential of VLPs in serological diagnostics. VLPs were confirmed to be heterogeneous in size morphology and maturation state. Yet, we show that many highly conformational and quaternary structure-dependent antibody epitopes found on virus particles are efficiently displayed on DENV1-4 VLP surfaces as well. Additionally, DENV VLPs can efficiently be used as antigens to deplete DENV patient sera from serotype specific antibody populations. This study aids in further understanding epitopic landscape of DENV VLPs and presents a comparative antigenic surface view of VLPs in respect to virus particles. We propose the use VLPs as a safe and practical alternative to infectious virus as a vaccine and diagnostic antigen.

Role of nuclear medicine and AIDS: Overview and perspective for future

The human immunodeficiency virus (HIV) is the causative agent for the expanding epidemic of the acquired immunodeficiency syndrome (AIDS). Sixteen million individuals were estimated to be infected worldwide with HIV by the World Health Organization in 1995, with over 10 million in Africa and one million in the USA. As the HIV cost in dollars and lives continues to rise it will become more important to understand AIDS and to foresee the potential role of nuclear medicine in HIV diseases. Nuclear medicine may have a role in the assessment of immune function, including the ability to predict if individuals can avoid progression to HIV+ status, if pre-AIDS to AIDS conversion can be prevented, and if an individual's immune status requires addition of prophylaxis. Also it can be used for disease detection at an early stage and determination of the extent of disease. It is especially useful to assist clinicians in optimizing therapy and assessing its efficacy. In the future new radiopharmaceuticals for detecting a specific infections and tumors will be needed. This will require collaborative efforts with basic scientists and clinicians working hand in hand to address specific issues related to AIDS

Background. Host genetic variation influences human immunodeficiency virus (HIV) infection and progression to AIDS. Here we used clinically well-characterized subjects from 5 pretreatment HIV/AIDS cohorts for a genome-wide association study to identify gene associations with rate of AIDS progression. Methods.  European American HIV seroconverters (n = 755) were interrogated for single-nucleotide polymorphisms (SNPs) (n = 700,022) associated with progression to AIDS 1987 (Cox proportional hazards regression analysis, co-dominant model). Results.  Association with slower progression was observed for SNPs in the gene PARD3B. One of these, rs11884476, reached genome-wide significance (relative hazard = 0.3; P =3. 370 × 10−9) after statistical correction for 700,022 SNPs and contributes 4.52% of the overall variance in AIDS progression in this study. Nine of the top-ranked SNPs define a PARD3B haplotype that also displays significant association with progression to AIDS (hazard ratio, 0.3; P = 3.220 × 10−8). One of these SNPs, rs10185378, is a predicted exonic splicing enhancer; significant alteration in the expression profile of PARD3B splicing transcripts was observed in B cell lines with alternate rs10185378 genotypes. This SNP was typed in European cohorts of rapid progressors and was found to be protective for AIDS 1993 definition (odds ratio, 0.43, P = .025). Conclusions. These observations suggest a potential unsuspected pathway of host genetic influence on the dynamics of AIDS progression. PMID:21502085

Feline immunodeficiency virus (FIV) is a naturally occurring lentivirus of domestic cats, and is the causative agent of feline AIDS. Similar to human immunodeficiency virus (HIV), the pathogenesis of FIV involves infection of lymphocytes and macrophages, and results in chronic progressive immune system collapse and death. Neuropathologic correlates of FIV infection have not yet been elucidated, and may be relevant to understanding HIV-associated neurologic disease (neuroAIDS). As in HIV, FIV strains have been shown to express differential tendencies towards development of clinical neuroAIDS. To interrogate viral genetic determinants that might contribute to neuropathogenicity, cats were exposed to two well-characterized FIV strains with divergent clinical phenotypes and a chimeric strain as follows: FIV(PPR) (PPR, relatively apathogenic but associated with neurologic manifestations), FIV(C36) (C36, immunopathogenic but without associated neurologic disease), and Pcenv (a chimeric virus consisting of a PPR backbone with substituted C36 env region). A sham inoculum control group was also included. Peripheral nerve conduction velocity, CNS imaging studies, viral loads and hematologic analysis were performed over a 12 month period. At termination of the study (350 days post-inoculation), brain sections were obtained from four anatomic locations known to be involved in human and primate lentiviral neuroAIDS. Histological and immunohistochemical evaluation with seven markers of inflammation revealed that Pcenv infection resulted in mild inflammation of the CNS, microglial activation, neuronal degeneration and apoptosis, while C36 and PPR strains induced minimal neuropathologic changes. Conduction velocity aberrations were noted peripherally in all three groups at 63 weeks post-infection. Pcenv viral load in this study was intermediate to the parental strains (C36 demonstrating the highest viral load and PPR the lowest). These results collectively suggest that (i) 3' C36

Full Text Available Abstract Introduction: Acquired immunodeficiency syndrome (AIDS is  a set of symptoms caused by decreases of the immune system that was infected by human immunodeficiency virus (HIV. Blood disorders often found in patient with HIV and associated with HIV infection. Mostly found disorders is anemia of chronic disease. The prevalence of anemia in HIV/AIDS patients reaches 70%. Oral manifestations of anemia are atrophy of the papillae on tongue, glossodynia, pallor, angular cheilitis, glossitis, aphthous ulcers/erosive lesions, candidiasis, and geographic tongue. There are many publications that uses anemia as indicator to determine the prognosis of HIV infection, thus the description of oral manifestation of anemia in the non-ARV HIV/AIDS patients is a necessity. The purpose of this study was to describe the oral manifestation of anemia in the non-ARV HIV/AIDS patients. Methods: The methods used were purposive random sampling. Samples were new HIV/AIDS patients who have not got antiretroviral (ARV treatment. The study included 40 patients in Teratai Clinic Hasan Sadikin Hospital Bandung. Results: Oral manifestations of anemia were found amongst non-ARV HIV/AIDS patients, which were candidiasis in  37 patients, glossodynia in 28 patients, glossitis in 10 patients, and angular cheilitis in 1 patient. Conclusion: From the study found that oral manifestations of anemia that found in non-ARV HIV/AIDS patients were candidiasis, glossodynia, glossitis and angular cheilitis. HIV/AIDS patients with anemia needed to treat more intensive for better prognosis and quality of life. Keywords: Anemia, HIV/AIDS, Candidiasis, Glossitis, Glossodynia

Defining Moments in MMWR History: The AIDS Epidemic, Pneumocystis Pneumonia --- Los Angeles 1981

Centers for Disease Control (CDC) Podcasts

2017-12-01

On June 5, 1981, MMWR published a report of Pneumocystis pneumonia in five previously healthy young gay men in Los Angeles, California. This report was later acknowledged as the first published account of what would become known as human immunodeficiency virus, or HIV, and acquired immunodeficiency syndrome, or AIDS. It was the first of many MMWR reports that led to a better understanding of this new condition. In this podcast, Dr. Harold Jaffe recalls CDC’s investigation and response to the AIDS Epidemic.  Created: 12/1/2017 by MMWR.   Date Released: 12/1/2017.

Human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) affects economic growths by reducing the human capitals are among the most poorly understood aspect of the AIDS epidemic. This article analyzes the effects of the prevalence of HIV and full-blown AIDS on a country's human capitals and economic growths. Using a fixed effect model for panel data 1990-2010 from the Asia, I explored the dynamic relationships among HIV/AIDS, economic growths, and human capitals within countries over time. The econometric effects concerned that HIV/AIDS plays an important role in the field of economic growths and it is measured as a change in real gross domestic product (GDP) per capita and human capitals. The modeling results for the Asian countries indicates HIV/AIDS prevalence that has a hurtful effect on GDP per capita by reducing human capitals within countries over time.

ABSTRACT The human body plays host to a wide variety of microbes, commensal and pathogenic. In addition to interacting with their host, different microbes, such as bacteria and viruses, interact with each other, sometimes in ways that exacerbate disease. In particular, gene expression of a number of viruses, including Kaposi's sarcoma-associated herpesvirus (KSHV), Epstein-Barr virus (EBV), and human immunodeficiency virus (HIV), is known to be regulated by epigenetic modifications induced by bacteria. These viruses establish latent infection in their host cells and can be reactivated by bacterial products. Viral reactivation has been suggested to contribute to periodontal disease and AIDS. In addition, bacterium-virus interactions may play a role in cancers, such as Kaposi's sarcoma, gastric cancer, and head and neck cancer. It is important to consider the effects of coexisting bacterial infections when studying viral diseases in vivo.

Interpersonal relationships and HIV/AIDS stigma in China

Full Text Available This study explores the implications of interpersonal relationships to HIV/AIDS stigma in Chinese society. The data were collected by 67 open-ended individual interviews. The study shows that HIV/AIDS stigma goes beyond fears about the risk of infection. Two interrelated themes, the social categorisation and bao, constitute the underlying principles in the structure of discourse. On the one hand, people with HIV/AIDS are typically represented as a deviant outgroup. They are believed to be retributed by the Heaven. However, the differentiation between ingroup and outgroup is not just simply based on HIV/AIDS infection. Instead, the boundary between the two is penetrable and is mediated by blood ties. One the other hand, the double-entendre of bao is called to play with respect to ingroup and outgroup. When a close kinship is taken into account, the belief of divine retribution fades out, and the belief of worldly reciprocation foregrounds. People with HIV/AIDS in this case straddle the very fine line between outgroup and ingroup. They are considered to be outgroup in the sense that HIV/AIDS as a virus/disease (a third party found in their body is contagious, and the physical boundary between “them” and “us” is therefore needed. Yet they are considered to be the part of ingroup, because either they are innocent, or they make use of the profit for righteousness. In both cases, they deserve to be reciprocally cared for by their family. The reciprocity hereby acts as an invisible binding force between the infected and the uninfected within a close kinship.

Full Text Available OBJECTIVE: The paper reviews data on drug use in relation to the spread of human immuno-deficiency virus and AIDS in South America and the Caribbean. METHODS: Information was gathered by thoroughly reviewing major bibliographic databanks, web sites of international institutions and regional networks working with substance misuse or human immunodeficiency virus and AIDS, and abstracts from conferences and meetings. RESULTS: Although some gaps remain, a growing body of evidence documents the significant role of injected cocaine in the Brazilian and Southern Cone epidemics. The Caribbean and the Andean areas have thus far been spared in large part from the spread of injection drug use and its consequences, but the situation has been changing in Southern Cone countries towards a higher prevalence of harmful injection habits. Additional challenges have been posed by the increasing availability of heroin in the Andean Area and the abuse of crack cocaine and its impact on the sexual transmission of human immunodeficiency virus in many cities. Harm reduction strategies have been established in most areas of Brazil and are gaining momentum in Argentina. Other countries in the Region still face serious limitations due to restrictive legislation and lack of broader support. CONCLUSION: Greater participation of Latin American and Caribbean countries in research protocols and continued debate on both successful and failed experiences should be encouraged in order to minimize existing barriers to the full adoption of effective measures to curb the human immunodeficiency virus and AIDS epidemic in this Region.RESUMEN OBJETIVO: En el trabajo se revisan los datos acerca del consumo de drogas en relación con la propagación del virus de la inmunodeficiencia humana y el sida en Amé-rica del Sur y el Caribe.

We assessed associations of herpes simplex virus types 1 and 2 (HSV-1 and -2), cytomegalovirus (CMV), and human herpesvirus 8 (HHV-8) infection with subclinical coronary atherosclerosis in 291 HIV-infected men in the Multicenter AIDS Cohort Study. Coronary artery calcium (CAC) was measured by non-contrast coronary CT imaging. Markers for herpesviruses infection were measured in frozen specimens collected 10-12 years prior to case identification. Multivariable logistic regression models and ordinal logistic regression models were performed. HSV-2 seropositivity was associated with coronary atherosclerosis (adjusted odds ratio [AOR]=4.12, 95% confidence interval [CI]=1.58-10.85) after adjustment for age, race/ethnicity, cardiovascular risk factors, and HIV infection related factors. Infection with a greater number of herpesviruses was associated with elevated CAC levels (AOR=1.58, 95% CI=1.06-2.36). Our findings suggest HSV-2 may be a risk factor for subclinical coronary atherosclerosis in HIV-infected men. Infection with multiple herpesviruses may contribute to the increased burden of atherosclerosis. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Background Antiretroviral therapy (ART) prevents human immunodeficiency virus (HIV) disease progression, mortality and transmission. We assess the impact of expanded HIV treatment for the prevention of Acquired Immunodeficiency Syndrome (AIDS)-related deaths and simulate four treatment scenarios for Nigeria and South Africa. Methods For 1990–2013, we used the Joint United Nations Programme on HIV/AIDS (UNAIDS) database to examine trends in AIDS deaths, HIV incidence and prevalence, ART coverage, annual AIDS death rate, AIDS death-to-treatment and HIV infections to treatment ratios for the top 30 countries with the highest AIDS mortality burden and compare them with data from high-income countries. We projected the 1990–2020 AIDS deaths for Nigeria and South Africa using four treatment scenarios: 1) no ART; 2) maintaining current ART coverage; 3) 90% ART coverage based on 2013 World Health Organization (WHO) ART guidelines by 2020; and 4) reaching the United Nations 90-90-90 Target by 2020. Findings In 2013, there were 1.3 million (1.1 million–1.6 million) AIDS deaths in the top 30 countries representing 87% of global AIDS deaths. Eight countries accounted for 58% of the global AIDS deaths; Nigeria and South Africa accounted for 27% of global AIDS deaths. The highest death rates per 1000 people living with HIV were in Central African Republic (91), South Sudan (82), Côte d’Ivoire (75), Cameroon (72) and Chad (71), nearly 8–10 times higher than the high-income countries. ART access in 2013 has averted as estimated 1,051,354 and 422,448 deaths in South Africa and Nigeria, respectively. Increasing ART coverage in these two countries to meet the proposed UN 90-90-90 Target by 2020 could avert 2.2 and 1.2 million deaths, respectively. Interpretation Over the past decade the expansion of access to ART averted millions of deaths. Reaching the proposed UN 90-90-90 Target by 2020 will prevent additional morbidity, mortality and HIV transmission. Despite progress

Feline immunodeficiency virus (FIV) is a lentivirus that causes AIDS in domestic cats, similar to human immunodeficiency virus (HIV)/AIDS in humans. The FIV accessory protein Vif abrogates the inhibition of infection by cat APOBEC3 restriction factors. FIV also encodes a multifunctional OrfA accessory protein that has characteristics similar to HIV Tat, Vpu, Vpr, and Nef. To examine the role of vif and orfA accessory genes in FIV replication and pathogenicity, we generated chimeras between two FIV molecular clones with divergent disease potentials: a highly pathogenic isolate that replicates rapidly in vitro and is associated with significant immunopathology in vivo, FIV-C36 (referred to here as high-virulence FIV [HV-FIV]), and a less-pathogenic strain, FIV-PPR (referred to here as low-virulence FIV [LV-FIV]). Using PCR-driven overlap extension, we produced viruses in which vif, orfA, or both genes from virulent HV-FIV replaced equivalent genes in LV-FIV. The generation of these chimeras is more straightforward in FIV than in primate lentiviruses, since FIV accessory gene open reading frames have very little overlap with other genes. All three chimeric viruses exhibited increased replication kinetics in vitro compared to the replication kinetics of LV-FIV. Chimeras containing HV-Vif or Vif/OrfA had replication rates equivalent to those of the virulent HV-FIV parental virus. Furthermore, small interfering RNA knockdown of feline APOBEC3 genes resulted in equalization of replication rates between LV-FIV and LV-FIV encoding HV-FIV Vif. These findings demonstrate that Vif-APOBEC interactions play a key role in controlling the replication and pathogenicity of this immunodeficiency-inducing virus in its native host species and that accessory genes act as mediators of lentiviral strain-specific virulence.

Full Text Available OBJECTIVE To identify vulnerabilities of elderly people with HIV/AIDS and the trajectory that they follow until reaching the diagnosis of the disease. METHOD Qualitative research conducted in specialized clinics in the state of São Paulo, from January to June 2011. Semi-structured interviews were conducted with 11 elderly people who were found to be infected with the virus at the age of 60 years or older. The interviews were analyzed using content analysis. RESULTS In this process four categories emerged, then analyzed with reference to the theoretical framework of vulnerability. CONCLUSION Late diagnosis of HIV infection or AIDS among the elderly happens in the secondary or tertiary service. Issues related to sexual life of the elderly are only questioned by health professionals after the diagnosis, also the time that condom use becomes absolute. It is believed that the investigation of the vulnerability of the elderly to HIV/AIDS allows for carrying out appropriate interventions for this population.

Full Text Available The incidence of Cherry necrotic rusty mottle virus (CNRMV and Cherry green ring mottle virus (CGRMV have recently been occurred in Korea, posing a problem for sweet cherry cultivation. Since infected trees have symptomless leaves or ring-like spots on the pericarp, it is difficult to identify a viral infection. In this study, the incidence of CNRMV and CGRMV in sweet cherry in Gyeongbuk province was surveyed using a newly developed duplex reverse transcriptase polymerase chain reaction (RT-PCR method that can detect both viruses in a single reaction. CNRMV and CGRMV co-infection rates were 29.6%, 53.6%, and 17.6%, respectively, in samples collected from three different sites (Daegu, Gyeongju and Gyeongsan in Gyeongbuk province during 2012 and 2013. This duplex RT-PCR method offers a simple, rapid, and effective way of identifying CNRMV and CGRMV simultaneously in sweet cherry trees, which can aid in the management of viral infections that could undermine yield.

A majority of pediatric patients and rare adult patients with the acquired immunodeficiency syndrome (AIDS) develop a chronic respiratory disorder referred to as lymphocytic interstitial pneumonitis (LIP). Efforts to identify an infectious agent responsible for this process so far have failed. In this study, frozen sections of lungs from patients with AIDS and pulmonary disease were tested by in situ molecular hybridization for the presence of cells infected with human T-cell lymphotropic virus type III (HTLV-III) and expressing viral RNA. In the case of an infant with LIP, a relatively high frequency (0.1%) of cells in the lung were found to be positive for HTLV-III RNA. This number is the lower limit of total cells infected since the in situ hybridization technique as applied in this study depends on expression of HTLV-III genes, and previous evidence indicates that a proportion of cells infected with HTLV-III may not express viral RNA. Moreover, this degree of infection of the lung is likely limited to LIP, since in ten patients with AIDS and pulmonary diseases other than LIP, only 0% to 0.002% of cells in lung were positive for viral RNA expression. Thus, HTLV-III may play a direct causal role in the development of LIP in infected patients, implicating its involvement in yet another of the diverse clinical diseases associated with this virus

Full Text Available Background: Adolescents knowledge with their safe practices pertaining to human immunodeficiency virus (HIV has a critical impact on the prevention of contracting and spreading HIV. Reports have shown that adolescents in the general setting engage in activities that enhance the spread of the virus. Aim: The study assessed school adolescent's HIV/acquired immune deficiency syndrome (AIDS knowledge, with its impact on their behaviors and attitudes regarding the infection. Materials and Methods: Two hundred randomly selected adolescent students from 10 different schools in the city metropolis were involved in the cross-sectional study. Primary data were collected using a validated self-administered questionnaire on students HIV/AIDS knowledge, attitude toward people living with HIV/AIDS (PLWHA, and safe practices preventing the spread of HIV/AIDS. Results: The study observed that majority of the students had good knowledge about HIV/AIDS, had good attitude toward PLWHA, and engaged in safe practices that prevent the spread of HIV. The sources of HIV/AIDS information were hospital, school, home, electronic, and print media. The study also found that HIV/AIDS knowledge instilled good attitudes and behavioral practices in the students. Conclusion: The study shows that school sex education, as well as health promotion campaigns through media platforms, could impact positively on the knowledge, attitude, and behavioral practices of adolescents in curbing the spread of HIV/AIDS.

Why we must keep up the war on AIDS.

A rebuttal is made to Neville Hodgkinson's article questioning the existence of the AIDS epidemic in view of the pressure on funds for overseas aid in order to explain why support is provided to international AIDS control programs. Some AIDS workers have questioned the reliability of AIDS statistics and challenged the conventional wisdom that the human immunodeficiency virus (HIV) causes illness and death. The British Medical Research Council and the Ugandan government have studied about 10,000 people in 15 villages in rural Masaka, southern Uganda. Adolescents and young adults infected with HIV-1 were 60 times more likely to die in the next year than those who were not infected. More than 50% of all adult deaths, and more than 80% of deaths in young adults, are associated with HIV-1. HIV-1 targets CD4 lymphocytes and kills them making people vulnerable to infections such as diarrhea and tuberculosis. In Africa, many of those infected with HIV die as a result of infections from which they would normally recover. In some parts of southern Uganda and northern Tanzania, the prevalence of adults infected with HIV has changed little over the past few years, hovering at 10-15%. In other areas, prevalence is nearer 30-40%. Condoms reduce infection risk and education and condom marketing is changing sexual behavior in Zaire, Zimbabwe, and Tanzania. British aid is designed to help countries tackle health issues in addition to HIV-AIDS faced by their people and to make the best use of cash. Predictions of drastic population decline across Africa, resulting from the relentless spread of HIV also undermined the efforts of African governments to restore both public and external confidence. Hundreds of medical and nursing staff working to improve the world's health draw attention to unnecessary expenditure and condemning waste. Yet none argue that the HIV epidemic is a myth.

The population of Middle Eastern immigrants in the US has been increasing dramatically over the past 30 years, growing from 200,000 in 1970 to 1.5 million in 2000. These immigrants and their descendants constitute an important new population of interest for public health and other social programmes. With this addition to the cultural diversity of American society, it is important for healthcare programmes to be responsive to the unique cultural needs of those of Middle Eastern origin and to include them in healthcare curricula. This need is particularly imperative for human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) intervention programmes, where the reduction of risky behaviours is essential to controlling the epidemic. When Middle Easterners emigrate to the US they must adjust to the American culture, which leads to preservation of some aspects of their culture and adjustment of behaviors to match American customs. This article aims to present sociocultural factors of HIV risk behaviours that are specific to Middle Eastern culture. The article also provides recommendations for HIV/AIDS-culturally appropriate intervention programmes.

Activation of human immunodeficiency virus by radiation

It was recently demonstrated that ultraviolet radiation (UVR) can induce the HIV promoter as well as activate the complete virus in cultured cells (Valerie et al., 1988). This and subsequent observations, reviewed in this article, suggest a possibility that radiation exposure may accelerate development of AIDS in HIV-infected individuals. They also indicate that studies on HIV activation by stressors, including radiation, may advance our understanding of some phenomena that follow HIV infection. (author)

Vacuolar myelopathy (VM) and tract pallor are poorly understood spinal tract abnormalities in patients with the acquired immunodeficiency syndrome (AIDS). We studied the ability of magnetic resonance imaging (MRI) to detect these changes in spinal cord specimens postmortem and whether criteria could be formulated which would allow these conditions to be differentiated from other lesions of the spinal cord in AIDS, such as lymphoma, cytomegalovirus (CMV) and human immunodeficiency virus (HIV) myelitis. We imaged 38 postmortem specimens of spinal cord. The MRI studies were interpreted blind. The specimens included cases of VM myelin pallor. CMV myeloradiculitis, HIV myelitis, lymphoma as well as normal cords, both HIV+ve and HIV-ve. MRI showed abnormal signal, suggestive of tract pathology, in 10 of the 14 cases with histopathological evidence of tract changes. The findings in VM and tract pallor on proton-density and T{sub 2}-weighted MRI were increased signal from the affected white-matter tracts, present on multiple contiguous slices and symmetrical in most cases. The pattern was sufficiently distinct to differentiate spinal tract pathology from other spinal cord lesions in AIDS. (orig.)

Full Text Available Feline immunodeficiency virus (FIV is widespread in feline populations and causes an AIDS-like illness in domestic cats. It is highly prevalent in several endangered feline species. In domestic cats FIV infection is a valuable small animal model for HIV infection. In recent years there has been a significant increase in interest in FIV, in part to exploit this, but also because of the potential it has as a human gene therapy vector. Though much less studied than HIV there are many parallels in the replication of the two viruses, but also important differences and, despite their likely common origin, the viruses have in some cases used alternative strategies to overcome similar problems. Recent advances in understanding the structure and function of FIV RNA and proteins and their interactions has enhanced our knowledge of FIV replication significantly, however, there are still many gaps. This review summarizes our current knowledge of FIV molecular biology and its similarities with, and differences from, other lentiviruses.

1989-01-01

In the case of Institut Pasteur v. United States, the Institut Pasteur (Pasteur) claimed that the National Cancer Institute (NCI) had breached express and implied contracts to share research on AIDS virus samples provided to NCI by Pasteur. NCI scientists allegedly used the samples to acquire information which allowed NCI to file patent applications for an AIDS blood test kit. The United States Claims Court dismissed the complaint by holding that the Institut Pasteur had not complied with certain administrative procedures required by the Contract Disputes Act before bringing its suit. The United States Court of Appeals for the Federal Circuit reversed the decision of the Claims Court by holding that the disputed contracts did not fit within the scope of the Contract Disputes Act. Soon after the Court of Appeals decision, President Reagan and Prime Minister Chirac announced a settlement agreement whereby the lawsuit was to be dropped, American and French scientists were to share credit for having discovered the AIDS virus, and both parties to the suit were to share the patent rights for the AIDS blood test kit. This settlement suggest that international legal disputes involving urgent scientific and medical matters may require dispute resolution techniques that serve as alternatives to national courts.

In consequence, an upsurge in the research on ZIKV was seen around the globe, with significant attainments over developing several effective diagnostics, drugs, therapies, and vaccines countering this life-threatening virus at an early step. State-of-art tools developed led the researchers to explore virus at the molecular level, and in-depth epidemiological investigations to understand the reason for increased pathogenicity and different clinical manifestations. These days, ZIKV infection is diagnosed based on clinical manifestations, along with serological and molecular detection tools. As, isolation of ZIKV is a tedious task; molecular assays such as reverse transcription-polymerase chain reaction (RT-PCR, real-time qRT-PCR, loop-mediated isothermal amplification (LAMP, lateral flow assays (LFAs, biosensors, nucleic acid sequence-based amplification (NASBA tests, strand invasion-based amplification tests and immune assays like enzyme-linked immunosorbent assay (ELISA are in-use to ascertain the ZIKV infection or Zika fever. Herein, this review highlights the recent advances in the diagnosis, surveillance, and monitoring of ZIKV. These new insights gained from the recent advances can aid in the rapid and definitive detection of this virus and/or Zika fever. The summarized information will aid the strategies to design and adopt effective prevention and control strategies to counter this viral pathogen of great public health concern.

A 35-years-old right-handed man admitted to our hospital with a worsening of dysarthria, left facial palsy and left hemiparesis for 2 days. Acquired immunodeficiency syndrome (AIDS) was diagnosed when he was 28 years old. At that time, he also was treated for syphilis. After highly active antiretroviral treatment (HAART) was introduced at the age of 35 years old, serum level of human immunodeficiency virus (HIV) was not detected, but the number of CD4+ T cells was still less than 200/μl. He had no risk factors of atherosclerosis including hypertension, diabetes and hyperlipidemia. He had neither coagulation abnormality nor autoimmune disease. Magnetic resonance imaging (MRI) showed acute ischemic infarction spreading from the right corona radiate to the right internal capsule without contrast enhancement. Stenosis and occlusion of intracranial arteries were not detected by MR angiography. Although argatroban and edaravone were administered, his neurological deficits were worsened to be difficult to walk independently. Cerebrospinal fluid (CSF) examination showed a mild mononuclear pleocytosis (16/μl).　Oligoclonal band was positive. The titer of anti-varicella zoster virus (VZV) IgG antibodies was increased, that indicated VZV reactivation in the central nervous system (CNS), although VZV DNA PCR was not detected. Therefore, acyclovir (750 mg/day for 2 weeks) and valaciclovir (3,000 mg/day for 1 month) were administered in addition to stroke therapy. He recovered to be able to walk independently 2 month after the admission.Angiography uncovered a saccular aneurysm of 3 mm at the end of branch artery of right anterior cerebral artery, Heubner artery, 28 days after the admission. We speculated that VZV vasculopathy caused by VZV reactivation in CNS was involved in the pathomechanism of cerebral infarction rather than HIV vasculopathy in the case.

A stochastic spatial model based on the Monte Carlo approach is developed to study the dynamics of human immunodeficiency virus (HIV) infection. We aim to propose a more detailed and realistic simulation frame by incorporating many important features of HIV dynamics, which include infections, replications and mutations of viruses, antigen recognitions, activations and proliferations of lymphocytes, and diffusions, encounters and interactions of virions and lymphocytes. Our model successfully reproduces the three-phase pattern observed in HIV infection, and the simulation results for the time distribution from infection to AIDS onset are also in good agreement with the clinical data. The interactions of viruses and the immune system in all the three phases are investigated. We assess the relative importance of various immune system components in the acute phase. The dynamics of how the two important factors, namely the viral diversity and the asymmetric battle between HIV and the immune system, result in AIDS are investigated in detail with the model.

West Africa occupies the third position with respect to the burden of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) globally, after Southern and East Africa. About 5 million adults and children are infected with the disease in the subregion, while HIV prevalence in the general population hovers around 2% and 5%. This paper attempts to investigate the impact of HIV/AIDS epidemic on human capital development in 11 West African countries over the period 1990 to 2011. The study used a dynamic panel data modeling approach, using first difference, difference generalized methods of moment, and system generalized methods of moment estimating techniques. Four measures of HIV/AIDS and 2 human capital measures were used in the study. The findings revealed that HIV/AIDS pandemic had negative and significant impact on human capital in West Africa. However, the statistical significance was more pronounced on life expectancy (a measure of human capital), while the negative impact on school enrolment (another human capital measure) was not significant. It is therefore recommended that the spread of HIV/AIDS disease in West Africa should be effectively controlled, while the number of infected persons undergoing antiretroviral therapy in the subregion should be increased to a near 100% coverage.

Mucosal immunity consists of innate and adaptive immune responses which can be influenced by systemic immunity. Despite having been the subject of intensive studies, it is not fully elucidated what exactly occurs after HIV contact with the female genital tract mucosa. The sexual route is the main route of HIV transmission, with an increased risk of infection in women compared to men. Several characteristics of the female genital tract make it suitable for inoculation, establishment of infection, and systemic spread of the virus, which causes local changes that may favor the development of infections by other pathogens, often called sexually transmitted diseases (STDs). The relationship of these STDs with HIV infection has been widely studied. Here we review the characteristics of mucosal immunity of the female genital tract, its alterations due to HIV/AIDS, and the characteristics of coinfections between HIV/AIDS and the most prevalent STDs.

This paper correlates changes in the brain demonstrated on F-18 fluorodeoxyglucose (FDG) positron emission tomographic (PET) scans and CT or MR images with disease severity in patients with acquired immunodeficiency syndrome (AIDS). Data from 30 patients who tested positive for human immunodeficiency virus (HIV) who were at various stages of AIDS, and who had undergone FDG PET, CT, and/or MR imaging were reviewed retrospectively. The average CD4 lymphocyte counts, an indicator of disease severity in AIDS, in 25 symptomatic (group I) and five healthy seropositive (group II) subjects were 300 and 694 cells/mm 3 , respectively. Cortical atrophy was present on CT and/or MR imaging in 92% in group I and only 20% in group II. Of the 17 patients in group I who underwent PET scans 11 demonstrated an elevated basal ganglia to frontal cortex (BG/FC) ratio of FDG uptake; only one of the four in group II had this finding

Full Text Available Abstract Background CCR5-restricted (R5 human immunodeficiency virus type 1 (HIV-1 variants cause CD4+ T-cell loss in the majority of individuals who progress to AIDS, but mechanisms underlying the pathogenicity of R5 strains are poorly understood. To better understand envelope glycoprotein (Env determinants contributing to pathogenicity of R5 viruses, we characterized 37 full-length R5 Envs from cross-sectional and longitudinal R5 viruses isolated from blood of patients with asymptomatic infection or AIDS, referred to as pre-AIDS (PA and AIDS (A R5 Envs, respectively. Results Compared to PA-R5 Envs, A-R5 Envs had enhanced fusogenicity in quantitative cell-cell fusion assays, and reduced sensitivity to inhibition by the fusion inhibitor T-20. Sequence analysis identified the presence of Asn 362 (N362, a potential N-linked glycosylation site immediately N-terminal to CD4-binding site (CD4bs residues in the C3 region of gp120, more frequently in A-R5 Envs than PA-R5 Envs. N362 was associated with enhanced fusogenicity, faster entry kinetics, and increased sensitivity of Env-pseudotyped reporter viruses to neutralization by the CD4bs-directed Env mAb IgG1b12. Mutagenesis studies showed N362 contributes to enhanced fusogenicity of most A-R5 Envs. Molecular models indicate N362 is located adjacent to the CD4 binding loop of gp120, and suggest N362 may enhance fusogenicity by promoting greater exposure of the CD4bs and/or stabilizing the CD4-bound Env structure. Conclusion Enhanced fusogenicity is a phenotype of the A-R5 Envs studied, which was associated with the presence of N362, enhanced HIV-1 entry kinetics and increased CD4bs exposure in gp120. N362 contributes to fusogenicity of R5 Envs in a strain dependent manner. Our studies suggest enhanced fusogenicity of A-R5 Envs may contribute to CD4+ T-cell loss in subjects who progress to AIDS whilst harbouring R5 HIV-1 variants. N362 may contribute to this effect in some individuals.

Full Text Available Viruses are pathogenic microorganisms that can inhabit and replicate in human bodies causing a number of widespread infectious diseases such as influenza, gastroenteritis, hepatitis, meningitis, pneumonia, acquired immune deficiency syndrome (AIDS etc. A majority of these viral diseases are contagious and can spread from infected to healthy human beings. The most important step in the treatment of these contagious diseases and to prevent their unwanted spread is to timely detect the disease-causing viruses. Gravimetric viral diagnostics based on quartz crystal microbalance (QCM transducers and natural or synthetic receptors are miniaturized sensing platforms that can selectively recognize and quantify harmful virus species. Herein, a review of the label-free QCM virus sensors for clinical diagnostics and point of care (POC applications is presented with major emphasis on the nature and performance of different receptors ranging from the natural or synthetic antibodies to selective macromolecular materials such as DNA and aptamers. A performance comparison of different receptors is provided and their limitations are discussed.

[No remedy for AIDS?].

Vila Mimosa, a site of street prostitution in Rio de Janeiro since the 1930s, is the place of work for over 2000 prostitution who charge an average of $3-4 per client. Several years ago the Association of Prostitutes of Rio de Janeiro (APRJ) was founded by Eunice Coelho Reis. APRJ membership has increased steadily and its list of accomplishments is impressive. A state hospital performs free medical examinations of APRJ members, and the Brazilian family planning association BEMFAM provides 180,000 condoms each month. AIDS control projects have also been successful, and no APRJ members have contracted HIV infection. In the country with the 4th highest rate of infection, the rigid norm of condom use adopted by the prostitutes of Vila Mimosa has led to effective prevention of sexually transmitted diseases. The prostitutes report however that a large proportion of their clients resist condom use, sometimes violently. The proportion of seropositive individuals who are women has been rising steadily. Family Health International estimates that the proportion of new cases among women has risen from 25% in 1990 to 40% at present. AIDS prevention campaigns are attempting to persuade women to "negotiate" condom use during sex. But power relations between the sexes place women at a disadvantage. Men often make the sexual decisions. Socialization patterns of females in Latin America are oriented to maternity. Passive sexual behavior has become a primary obstacle to adoption of safer sex practices. The World Health Organization estimates that currently 9-11 million persons are latent carriers of the HIV virus. Prostitution originating in poverty and unemployment, the vulnerability of adolescents who begin their sexual lives with little knowledge of contraception or sexually transmitted diseases, and the lack of sex education that transcends the biological to consider interpersonal relations are all factors that hinder AIDS prevention.

Previous studies demonstrated that immunization of macaques with simian immunodeficiency virus (SIV) Gag-Pol and Env recombinants of the attenuated poxvirus modified vaccinia virus Ankara (MVA) provided protection from high viremia and AIDS following challenge with a pathogenic strain of SIV. Although all animals became infected, plasma viremia was significantly reduced in animals that received the MVA-SIV recombinant vaccines compared with animals that received nonrecombinant MVA. Most importantly, the reduction in viremia resulted in a significant increase in median and cumulative survival. Continued analysis of these animals over the subsequent 9 years has shown that they maintain a survival advantage, although all but two of the macaques have progressed to AIDS. Importantly, improved survival correlated with preservation of memory CD4(+) T cells in the peripheral blood. The greatest survival advantage was observed in macaques immunized with regimens containing SIV Env, and the titer of neutralizing antibodies to the challenge virus prior to or shortly following challenge correlated with preservation of CD4(+) T cells. These data are consistent with a role for neutralizing antibodies in nonsterilizing protection from high viremia and associated memory CD4(+) T-cell loss.

Sexuality and Aging: discussions about AIDS

Full Text Available The aging population as well as the sexual liberation has caused many taboos to be broken, and even greater access to drugs that stimulate sexual activity provided for the elderly a sense of greater security to maintain sexual activity, this has generated an increase in cases of AIDS in these individuals. AIDS is a disease caused by the HIV virus that affects the body's immune system and presented as one of the most complex and challenging ever faced by mankind pandemics. Sexuality in the elderly that was neglected by researchers, professionals and society in general, until very recently, today is cause for concern. Based on this, the objective of this study was a reflection on the process of aging of the population and a rising rate of HIV infection among the elderly. It is intended to emphasize that, despite its increase, this segment still appears to be invisible to the eyes of society and the state and that the frequency and quality of sexual activity has not been accompanied by information and actions for the prevention of sexually transmitted diseases that portion of the population.

HIV-1 variants evolving in AIDS patients frequently show increased replicative capacity compared to those present during early asymptomatic infection. It is known that late stage HIV-1 variants often show an expanded coreceptor tropism and altered Nef function. In the present study we investigated whether enhanced HIV-1 LTR promoter activity might also evolve during disease progression. Our results demonstrate increased LTR promoter activity after AIDS progression in 3 of 12 HIV-1-infected individuals studied. Further analysis revealed that multiple alterations in the U3 core-enhancer and in the transactivation-response (TAR) region seem to be responsible for the enhanced functional activity. Our findings show that in a subset of HIV-1-infected individuals enhanced LTR transcription contributes to the increased replicative potential of late stage virus isolates and might accelerate disease progression

We assessed non-liver-related non-acquired immunodeficiency syndrome (AIDS)-related (NLR-NAR) events and mortality in a cohort of human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients treated with interferon (IFN) and ribavirin (RBV), between 2000 and 2008. The censoring date was May 31, 2014. Cox regression analysis was performed to assess the adjusted hazard rate (HR) of overall death in responders and nonresponders. Fine and Gray regression analysis was conducted to determine the adjusted subhazard rate (sHR) of NLR deaths and NLR-NAR events considering death as the competing risk. The NLR-NAR events analyzed included diabetes mellitus, chronic renal failure, cardiovascular events, NLR-NAR cancer, bone events, and non-AIDS-related infections. The variables for adjustment were age, sex, past AIDS, HIV transmission category, nadir CD4 + T-cell count, antiretroviral therapy, HIV RNA, liver fibrosis, HCV genotype, and exposure to specific anti-HIV drugs. Of the 1,625 patients included, 592 (36%) had a sustained viral response (SVR). After a median 5-year follow-up, SVR was found to be associated with a significant decrease in the hazard of diabetes mellitus (sHR, 0.57; 95% confidence interval [CI], 0.35-0.93; P = 0.024) and decline in the hazard of chronic renal failure close to the threshold of significance (sHR, 0.43; 95% CI, 0.17-1.09; P = 0.075). Our data suggest that eradication of HCV in coinfected patients is associated not only with a reduction in the frequency of death, HIV progression, and liver-related events, but also with a reduced hazard of diabetes mellitus and possibly of chronic renal failure. These findings argue for the prescription of HCV therapy in coinfected patients regardless of fibrosis stage. (Hepatology 2017;66:344-356). © 2017 The Authors.

This paper explores the impact that the presence of the Human Immunodeficiency Virus has had on the care of pregnant and childbearing women in Victoria and on my professional life as a midwife in private practice and a midwife educator. It provides an overview of my personal experience and discusses how the issues associated with HIV/AIDS have gradually infiltrated the area of midwifery care in our hospital system. The prejudices and practices of the dominant patriarchal medical system have resulted in women being oppressed and controlled in pregnancy and labour in institutions that are supposed to be there to serve their needs.

Kaposi's Sarcoma (KS) is a proliferation of aberrant vascular structures lined by spindle cells, and is caused by a gammaherpes virus (HHV8/KSHV). Its course is aggravated by co-infection with HIV-1, where the timing of infection with HIV-1 and HHV8 is important for the clinical outcome. In order to better understand the pathogenesis of KS, we have analysed tissue from two AIDS-KS lesions, and from normal skin by serial analysis of gene expression (SAGE). Semi-quantitative RT-PCR was then used to validate the results. The expression profile of AIDS-related KS (AIDS-KS) reflects an active process in the skin. Transcripts of HHV8 were found to be very low, and HIV-1 mRNA was not detected by SAGE, although it could be found using RT-PCR. Comparing the expression profile of AIDS-KS tissue with publicly available SAGE libraries suggested that AIDS-KS mRNA levels are most similar to those in an artificially mixed library of endothelial cells and leukocytes, in line with the description of KS lesions as containing spindle cells with endothelial characteristics, and an inflammatory infiltrate. At least 64 transcripts were found to be significantly elevated, and 28 were statistically downregulated in AIDS-KS compared to normal skin. Five of the upregulated mRNAs, including Tie 1 and sialoadhesin/CD169, were confirmed by semi-quantitative PCR to be elevated in additional AIDS-KS biopsies. Antibodies to sialoadhesin/CD169, a known marker of activated macrophages, were shown to specifically label tumour macrophages. The expression profile of AIDS-KS showed 64 genes to be significantly upregulated, and 28 genes downregulated, compared with normal skin. One of the genes with increased expression was sialoadhesin (CD169). Antibodies to sialoadhesin/CD169 specifically labelled tumour-associated macrophages, suggesting that macrophages present in AIDS-KS lesions belong to a subset of human CD169+ macrophages

A majority of human immunodeficiency virus type 1 (HIV-1) infected individuals display a rapid loss of CD4+ lymphocytes with fast progression towards overt acquired immunodeficiency syndrome (AIDS). However, a small proportion of individuals infected by HIV-1 remain immunologically intact for many years. In order to identify factors that might influence the pathogenesis of HIV-1 infection, 21 Italian mothers and 11 Swedish homosexual men were studied for the presence of autologous neutralizing antibodies in serum, biological phenotype of virus isolates and envelope variable region 3 (V3) sequences. The results were compared to the risk of mother-to-child transmission and progression of the disease. The presence of a neutralizing antibody response to the autologous virus as well as a virus with slow replicative capacity were linked both to low risk of mother-to-child transmission and non-progression of the disease. Patients whose peripheral blood mononuclear cells contained a mutation in the tip of the V3 loop (Arg318 to serine, lysine or leucine) significantly more often had neutralizing antibodies to autologous virus isolates containing arginine at this position. Thus, it appears that the interplay and balance between neutralizing antibody response of the host and the biological phenotype of HIV-1 strongly influence pathogenesis.

Background People with human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS), are at increased risk for cancer. Highly active antiretroviral therapy [(HAART), widely available since 1996] has resulted in dramatic declines in AIDS-related deaths. Methods We evaluated cancer as a cause of death in a U.S. registry-based cohort of 83,282 people with AIDS (1980–2006). Causes of death due to AIDS-defining cancers (ADCs) and non-AIDS-defining cancers (NADCs) were assessed. We evaluated mortality rates and the fraction of deaths due to cancer. Poisson regression assessed rates according to calendar year of AIDS onset. Results Overall mortality declined from 302 (1980–1989), to 140 (1990–1995), to 29 per 1,000 person-years (1996–2006). ADC mortality declined from 2.95 (1980–1989) to 0.65 per 1,000 person-years (1996–2006) (PAIDS-related deaths. Non-Hodgkin lymphoma was the commonest cancer-related cause of death (36% during 1996–2006). Likewise, NADC mortality declined from 2.21 to 0.84 per 1,000 person-years (1980–1989 vs. 1996–2006, PAIDS, cancers account for a growing fraction of deaths. Improved cancer prevention and treatment, particularly for non-Hodgkin lymphoma and lung cancer, would reduce mortality among people with AIDS. PMID:20825305

After the forest. AIDs as ecological collapse in Thailand.

Science.gov (United States)

Usher, A D

1992-01-01

Numerous parallels can be drawn between the systematic destruction of Thailand's forests and the emergence, in the same time period, of acquired immunodeficiency syndrome (AIDS) as an irreversible societal crisis. Both the disintegration of the body's defense system implicit in AIDS and the erosion of Thailand's ecosystem provoked by deforestation policies are examples of assaults by capitalist economic policies on previously self-regulating systems. Centralization and industrial development have driven a substantial proportion of young Thai villagers to the cities, where they sell their labor as sex workers (there may be as many as 2 million prostitutes in Thailand) or become heroin users. Conservative estimates project 1.6 million AIDS-infected Thais by the end of 1995. Just as generally benign conditions such as the common cold can annihilate a body ravaged by the AIDS virus, Thailand's ecosystem, degraded by unregulated logging and state-subsidized, for-profit rubber planting, is no longer able to absorb natural occurrences such as heavy rainfall. The loss of forestland--the traditional source of food, shelter, tools, and medicine and the repository of cultural icons--has forced villagers to obtain cash to meet their needs, and Thailand's sex industry offers one of the highest rates of remuneration. Legislation enacted in response to AIDS and deforestation shares an emphasis on the victims (e.g., the prostitutes and not their clients or the owners of sex establishments, and impoverished forest squatters rather than plantation companies and land speculators). A powerful, combative environmental movement is successfully resisting government attempts to destroy living communities. Needed as well is resistance on the part of women growing up in the age of AIDS to societal definitions that polarize females (virgins and prostitutes) and uphold one-sided monogamy.

The profile of the dermatoses in children with the HIV virus at the Fundação de Medicina Tropical do Amazonas.

Dias, Eleonora Dantas; Cunha, Maria da Graça Souza; Talhari, Sinésio

2012-01-01

The Acquired Immunodeficiency Syndrome (AIDS) constitutes a sub-epidemic in Brazil. Due to the increasing number of women infected by the virus, the vertical transmission increased substantially, and due to the lack of adequate prophylactic treatment, many children are infected and show manifestations of the disease in early ages. Multiple systems are affected by the HIV virus, and the skin is often the first organ to be involved. The objective of this study is to analyze the clinic, dermatological and epidemiological profiles of children carriers of the virus in the City of Manaus aiming at identifying the most frequent dermatoses that affect these children and try to relate these dermatoses to the immunologic deterioration. A study was conducted where children carriers of the HIV virus from the Fundação Alfredo da Matta and Fundação de Medicina Tropical were studied from March 2007 to July 2008. These children were submitted to dermatological and laboratorial exams such as viral load dosage and CD4+ and CD8+ counts. During the study period, 70 HIV + children were examined; all of them had AIDS and had been contaminated by vertical transmission. The average number of dermatoses by children was 1.73, and 95.5% had at least one dermatosis during the study period. The most frequent manifestations were atopic dermatitis (22.9%), childhood prurigo (20%) and warts (18,6%). Children with HIV/AIDS have more skin disorders than children without HIV/AIDS. There was no statistical difference between the children in the group using ARVT and the group that wasn't using it.

Hibiscus chlorotic ringspot virus is a positive-sense monopartite single-stranded RNA virus that belongs to the Carmovirus genus of the Tombusviridae family. Authentic virus harvested from infected host kenaf leaves was purified and virus crystals were grown in multiple conditions. One of the crystals diffracted to 3.2 Å resolution and allowed the collection of a partial data set. Hibiscus chlorotic ringspot virus (HCRSV) is a positive-sense monopartite single-stranded RNA virus that belongs to the Carmovirus genus of the Tombusviridae family, which includes carnation mottle virus (CarMV). The HCRSV virion has a 30 nm diameter icosahedral capsid with T = 3 quasi-symmetry containing 180 copies of a 38 kDa coat protein (CP) and encapsidates a full-length 3.9 kb genomic RNA. Authentic virus was harvested from infected host kenaf leaves and was purified by saturated ammonium sulfate precipitation, sucrose density-gradient centrifugation and anion-exchange chromatography. Virus crystals were grown in multiple conditions; one of the crystals diffracted to 3.2 Å resolution and allowed the collection of a partial data set. The crystal belonged to space group R32, with unit-cell parameters a = b = 336.4, c = 798.5 Å. Packing considerations and rotation-function analysis determined that there were three particles per unit cell, all of which have the same orientation and fixed positions, and resulted in tenfold noncrystallography symmetry for real-space averaging. The crystals used for the structure determination of southern bean mosaic virus (SBMV) have nearly identical characteristics. Together, these findings will greatly aid the high-resolution structure determination of HCRSV

Full Text Available Non-Hodgkin's lymphoma of B-cell type is the second most common neoplasm after Kaposi's sarcoma, among patients with human immunodeficiency virus infection. Most non-Hodgkin's lymphoma cases that are associated with acquired immunodeficiency syndrome involve extranodal sites, especially the digestive tract and the central nervous system. We report a case of primary lymphoma of the duodenum in a patient with AIDS. Upper gastrointestinal endoscopy revealed pseudopolypoid masses found in the second portion of the duodenum. A complete diagnostic study including histological, immunohistochemical and virological analyses showed high-grade B-cell Burkitt's lymphoma. The Epstein-Barr virus genome was detected in biopsies by immunohistochemical and in situ hybridization.O linfoma não-Hodgkin de células B é a segunda neoplasia mais comum em pacientes com infecção pelo vírus da imunodeficiência humana depois do sarcoma de Kaposi.

Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) is a complex healthcare problem. Research has demonstrated that negative attitudes affect healthcare provision. The purpose of this study was to compare nursing students' attitudes using the AIDS Attitude Scale (AAS). A descriptive, cross-sectional study was conducted in nursing schools in Istanbul, Turkey, and in Upstate New York (NY). Baccalaureate nursing students (n = 613) from both countries completed the questionnaire. Demographic data, overall AAS attitudes, and attitudes within each subscale were compared. Analyses included frequency and percentages of the grouped variables, arithmetic means and standard deviations, t-test for independent samples, and multiple analysis of variance. Upstate NY students' mean total AAS scores were significantly more positive toward HIV+ patients than Turkish students'. Scores for Professional Resistance and Emotions subscales were significantly more positive for the Upstate NY students, but Fear of Contagion was not. Upstate NY students had more negative attitudes in the contexts of job risk and eating in a restaurant where the chef has AIDS; more professional resistance to referring patients and training specialists for HIV/AIDS patients; and lower tender feelings for people with HIV/AIDS (p < .01 for each). Improvement in students' attitudes is beneficial for promoting nonjudgmental, compassionate care for the HIV+ population. © 2014 Wiley Periodicals, Inc.

Pragmatic Acts In HIV/AIDS Social Management Advertisements

Full Text Available Studies on the social management of HIV and AIDS have focused on how awareness about HIV and AIDS has been created through organised and interpersonal communication. These studies have not investigated context-constrained language use in the advertisements on the disease despite the wide coverage and potential effectiveness of the public sensitisation about HIV and AIDS. This study, therefore, investigated the pragmatic features of language in selected HIV and AIDS management advertisements with a view to identifying the pragmatic acts of the language. Aspects of pragmatic act theory, noted for negotiability of meaning context based interactional situations was adopted for the research. All the 25 advertisements broadcast between December 2006 and June 2009, to all African countries on both private and government-owned television stations in Nigeria by an International non-governmental agency known as 'it begins with you' (YOU constituted the data. Fifty–four utterances were generated from the adverts and were subjected to qualitative analysis and reported in simple percentages. Six pragmatic functions manifested in the advertisements: Co-opting and Projecting were realised through inference (INF, shared situational knowledge (SSK and relevance (REL to bring the audience into the war against HIV/AIDS. Encouraging and Emboldening were projected through SSK and INF to motivate the audience to go for HIV test and speak openly about the virus. Instigating was done using indirect speech act to empower the female against discrimination and stigmatisation. Advising was achieved through SSK and INF to promote fidelity and safe sexual behaviour. The analysis of YOU advertisements through pragmatic act theory presupposes that pragmatic functions were exploited by the advertisers to sensitise the audience, promote social ties and project into an HIV free generation.

Opportunistic esophagitis in AIDS: Radiographic diagnosis

International Nuclear Information System (INIS)

Levine, M.S.; Woldenberg, R.; Herlinger, H.; Laufer, I.

1987-01-01

Between 1983 and 1986, 35 of 90 patients with acquired immunodeficiency syndrome (AIDS) had double-contrast esophagograms to rule out opportunistic esophagitis. The radiographs were reviewed without knowledge of the clinical or endoscopic findings. Candida esophagitis was diagnosed radiographically in 17 patients who had varying degrees of plaque formation and viral esophagitis in three who had discrete ulcers without plaques. All three patients with viral esophagitis (herpes in 2 and cytomegalo virus in one) and 15 of 17 with Candida esophagitis had endoscopic and/or clinical corroboration of the radiographic diagnosis. Thus, the authors' experience suggests that fungal and viral esophagitis can often be differentiated on double-contrast esophagography, so that appropriate antifungal or antiviral therapy can be instituted without need for endoscopic intervention

Full Text Available Culture plays a significant role in people’s lives in Zambia and in Africa as a whole. Consequently, there is a need to take Zambian or African culture seriously in order to look at the salient elements of cultural practices in rites of passage that influence the spread of HIV and AIDS. This article analyses four rites of passage associated with birth, puberty, marriage and death. There are numerous rites of passage in Zambian culture. Some of these rites help to curb the spread of HIV and AIDS, whilst others exacerbate the spread of the virus. Using the Reformed Church in Zambia Bible Study Method of Subgroups, discussions were held that allowed victims of cultural practices to tell their stories using the narrative model. This article sought to shed light on cultural practices that exacerbate HIV and AIDS and more importantly, provide culturally sensitive alternatives to these harmful practices.

Global issues in pediatric nutrition: AIDS.

Science.gov (United States)

Ball, C S

1998-10-01

Nutrition is a final common pathway in chronic disease, and weight loss is a major manifestation of acquired immunodeficiency syndrome (AIDS). In sub-Saharan Africa, studies have shown that 25% of children with malnutrition have human immunodeficiency virus (HIV) infection, although patterns of malnutrition are indistinguishable from those who are HIV negative. Breast-feeding increases the risk of vertical transmission, and the overall risk versus benefit needs continuing careful consideration in relation to local mortality from gastroenteritis and malnutrition. Chronic diarrhea is much more common in HIV-infected children in Africa and may have a multiplicity of causes, including infection with adherent forms of Escherichia coli, protozoa, and even direct HIV infection of intestinal mucosal cells. The HIV wasting syndrome produces reduction in bioelectrical impedence, fat, lean body mass, and body cell mass, but the changes can be predicted from equations used in starvation states. Micronutrients may be important, but observed changes may be due to immune mediator activation, rather than malnutrition. Calorie supplementation is beneficial when delivered by any route, but is likely to produce the greatest positive change when CD4 counts are highest in relation to calorie intake. Paradoxically, HIV-infected children may be obese early in the disease until AIDS develops. There is an inextricable link between disease and nutritional status. In children with AIDS wasting syndrome, a low CD4 count and high viral load are likely so that effective antiviral treatment may ultimately produce the greatest improvement in health, including nutritional status.

Influenza A virus transmission via respiratory aerosols or droplets as it relates to pandemic potential

Science.gov (United States)

Richard, Mathilde; Fouchier, Ron A.M.

2015-01-01

Many respiratory viruses of humans originate from animals. For instance, there are now eight paramyxoviruses, four coronaviruses and four orthomxoviruses that cause recurrent epidemics in humans but were once confined to other hosts. In the last decade, several members of the same virus families have jumped the species barrier from animals to humans. Fortunately, these viruses have not become established in humans, because they lacked the ability of sustained transmission between humans. However, these outbreaks highlighted the lack of understanding of what makes a virus transmissible. In part triggered by the relatively high frequency of occurrence of influenza A virus zoonoses and pandemics, the influenza research community has started to investigate the viral genetic and biological traits that drive virus transmission via aerosols or respiratory droplets between mammals. Here we summarize recent discoveries on the genetic and phenotypic traits required for airborne transmission of zoonotic influenza viruses of subtypes H5, H7 and H9 and pandemic viruses of subtypes H1, H2 and H3. Increased understanding of the determinants and mechanisms of respiratory virus transmission is not only key from a basic scientific perspective, but may also aid in assessing the risks posed by zoonotic viruses to human health, and preparedness for such risks.

2003-01-01

To analyze the social representation of AIDS in a group of high school students aged 16 to 23 years in Mexico City. A non-probabilistic, cross-sectional research was carried out in a public high school in Mexico City. Students of all grades were invited to participate in the study, which took place between 1999 and 2000. Forty-six students participated; 28% male and 72% female. This exploratory field study consisted of three phases, each to address one of three dimensions: cognitive using free association techniques, representational field using semi-structured interviews; and context attitude by means of two discussion groups. In the latter, the information was previously collected for discussion. The cognitive nucleus on AIDS included the association between sex, disease, and death. The representational field of AIDS is constructed around the transmission-prevention unit. Construct elements are virus, contagion, sex, protection, and condom. An ambivalent attitude was identified towards HIV prevention and transmission: "We are only half responsible". Situations such as "rape, blood transfusions, infected syringes" were prominent in the discussion group, deemed beyond their control to prevent transmission, thus explaining the group's ambivalent attitude towards prevention. The usefulness of condoms was associated with prevention of pregnancy rather than with prevention of sexually transmitted infections. The social representation of HIV/AIDS in young students conforms a multidimensional corpus where different elements of scientific order and common sense converge and interact, such as beliefs, myths, taboos, and fears. All of these contribute to construct the meaning of AIDS. The English version of this paper is available at:http://www.insp.mx/salud/index.html.

Visceral leishmaniasis (VL) and human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) co-infection has been a research topic of interest worldwide. In Brazil, it has been observed that there is a relative underreporting and failure in the understanding and management of this important association. The aim of this study was to analyze epidemiological and clinical aspects of patients with VL with and without HIV/AIDS. We conducted an observational and analytical study of patients with VL followed in a Reference Service in the State of Maranhão, Brazil from 2007-2013. In total 126 patients were enrolled, of which 61 (48.4%) were co-infected with HIV/AIDS. There were more males among those with HIV/AIDS (85.2%, P>0.05) or with VL only (81.5%, P>0.05). These findings significantly differed based on age group (PHIV/AIDS co-infection, respectively. The incidence of diarrhea and splenomegaly significantly differed between the two groups (P=0.0014 and P=0.019, respectively). The myelogram parasitic examination was used most frequently among those with HIV/AIDS (91.8%), followed by those with VL only (69.2%). VL recurrences and mortality were significantly higher in the HIV/AIDS co-infected patients (PHIV/AIDS co-infection were mostly adult men. Diarrhea was more frequent in HIV/AIDS co-infected patients, whereas splenomegaly was more common in patients with VL only. In the group of HIV/AIDS co-infected patients, there was a higher rate of VL recurrence and mortality.

[Consensus statement on assistance to women with human immunodeficiency virus infection in the health care sector. National AIDS Plan (PNS) and AIDS Study Group (GeSIDA)].

2014-02-01

To develop a consensus document on clinical recommendations for the health care of women with human immunodeficiency virus (HIV) infection. We assembled a panel of experts appointed by the Secretariat of the National AIDS Plan and GeSIDA that included internal medicine physicians with expertise in the field of HIV infection, gynecologists, pediatricians and psychologists, and two panel members acting as coordinators. Scientific information was reviewed in publications and conference reports up to October 2012. In keeping with the criteria of the Infectious Disease Society of America, two levels of evidence were applied to support the proposed recommendations: the strength of the recommendation according to expert opinion (A, B, C), and the level of empirical evidence (i, ii, iii), already used in previous documents from SPNS/GeSIDA. We provide multiple recommendations for the clinical management of women with HIV infection, considering both the diagnostic and possible therapeutic strategies. The consensus recommends gender mainstreaming in health care, and promoting training for healthcare professionals in order to avoid gender bias. With currently available data it seems that the effectiveness of the treatment is the same in both men and women, there being no limitation as to the use of any antiretroviral for this reason. Women have more treatments suspended for reasons other than virological failure, thus they require better monitoring. This document presents recommendations for addressing women with HIV infection. This must be multidisciplinary, taking into account the differences that can be found in the diagnosis, disease development, and treatment between men and women.

In order to assess the applicability of multiplexed fluorescence in situ hybridization (FISH) assay for the clinical setting, we conducted retrospective analysis of 110 formalin-stored diarrheic stool samples from human immunodeficiency virus (HIV)/AIDS patients with intestinal microsporidiosis collected between 1992 and 2003. The multiplexed FISH assay identified microsporidian spores in 94 of 110 (85.5%) samples: 49 (52.1%) were positive for Enterocytozoon bieneusi, 43 (45.8%) were positive for Encephalitozoon intestinalis, 2 (2.1%) were positive for Encephalitozoon hellem, and 9 samples (9.6%) contained both E. bieneusi and E. intestinalis spores. Quantitative spore counts per ml of stool yielded concentration values from 3.5 × 103 to 4.4 × 105 for E. bieneusi (mean, 8.8 × 104/ml), 2.3 × 102 to 7.8 × 104 (mean, 1.5 × 104/ml) for E. intestinalis, and 1.8 × 102 to 3.6 × 102 for E. hellem (mean, 2.7 × 102/ml). Identification of microsporidian spores by multiplex FISH assay was more sensitive than both Chromotrope-2R and CalcoFluor White M2R stains; 85.5% versus 72.7 and 70.9%, respectively. The study demonstrated that microsporidian coinfection in HIV/AIDS patients with intestinal microsporidiosis is not uncommon and that formalin-stored fecal samples older than 10 years may not be suitable for retrospective analysis by techniques targeting rRNA. Multiplexed FISH assay is a reliable, quantitative fluorescence microscopy method for the simultaneous identification of E. bieneusi, E. intestinalis, and E. hellem, as well as Encephalitozoon cuniculi, spores in fecal samples and is a useful tool for assessing spore shedding intensity in intestinal microsporidiosis. The method can be used for epidemiological investigations and applied in clinical settings. PMID:17287331

The spread of human immunodeficiency virus(HIV)infection may result in an increased likelihood of surgery in patients with HIV infection. We treated a patient with intracranial malignant lymphoma associated with acquired immunodeficiency syndrome(AIDS)caused by HIV infection. The recommendations of the countermeasure manual for AIDS were followed. Only surgical staff without finger injury or inflammation were permitted to be involved in the operation. All staff were dressed in a waterproof, full-body surgical gown, and wore double gloves, double foot covers, and an N95 mask. The surgery could be performed safely with such infection control measures. Histological examination revealed a diffuse large B-cell lymphoma. The patient was referred to the Division of Infectious Diseases and Respiratory Medicine for chemotherapy.

HIV-1 Tat and AIDS-associated cancer: targeting the cellular anti-cancer barrier?

Directory of Open Access Journals (Sweden)

Daniel René

2008-05-01

Full Text Available Abstract The acquired immunodeficiency syndrome (AIDS is accompanied by a significant increase in the incidence of neoplasms. Several causative agents have been proposed for this phenomenon. These include immunodeficiency and oncogenic DNA viruses and the HIV-1 protein Tat. Cancer in general is closely linked to genomic instability and DNA repair mechanisms. The latter maintains genomic stability and serves as a cellular anti-cancer barrier. Defects in DNA repair pathway are associated with carcinogenesis. This review focuses on newly discovered connections of the HIV-1 protein Tat, as well as cellular co-factors of Tat, to double-strand break DNA repair. We propose that the Tat-induced DNA repair deficiencies may play a significant role in the development of AIDS-associated cancer.

Given the challenges in exploring lifelong therapy with little side effect for human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) cases, there is increasing interest in developing traditional Chinese medicine (TCM) treatments based on specific TCM syndrome. However, there are few objective and biological evidences for classification and diagnosis of HIV/AIDS TCM syndromes to date. In this study, iTRAQ-2DLC-MS/MS coupled with bioinformatics were firstly employed for comparative proteomic profiling of top popular TCM syndromes of HIV/AIDS: accumulation of heat-toxicity (AHT) and Yang deficiency of spleen and kidney (YDSK). It was found that for the two TCM syndromes, the identified differential expressed proteins (DEPs) as well as their biological function distributions and participation in signaling pathways were significantly different, providing biological evidence for the classification of HIV/AIDS TCM syndromes. Furthermore, the TCM syndrome-specific DEPs were confirmed as biomarkers based on western blot analyses, including FN1, GPX3, KRT10 for AHT and RBP4, ApoE, KNG1 for YDSK. These biomarkers also biologically linked with the specific TCM syndrome closely. Thus the clinical and biological basis for differentiation and diagnosis of HIV/AIDs TCM syndromes were provided for the first time, providing more opportunities for stable exertion and better application of TCM efficacy and superiority in HIV/AIDS treatment.

Sampling methods for recovery of human enteric viruses from environmental surfaces.

Science.gov (United States)

Turnage, Nicole L; Gibson, Kristen E

2017-10-01

Acute gastroenteritis causes the second highest infectious disease burden worldwide. Human enteric viruses have been identified as leading causative agents of acute gastroenteritis as well as foodborne illnesses in the U.S. and are generally transmitted by fecal-oral contamination. There is growing evidence of transmission occurring via contaminated fomite including food contact surfaces. Additionally, human enteric viruses have been shown to remain infectious on fomites over prolonged periods of time. To better understand viral persistence, there is a need for more studies to investigate this phenomenon. Therefore, optimization of surface sampling methods is essential to aid in understanding environmental contamination to ensure proper preventative measures are being applied. In general, surface sampling studies are limited and highly variable among recovery efficiencies and research parameters used (e.g., virus type/density, surface type, elution buffers, tools). This review aims to discuss the various factors impacting surface sampling of viruses from fomites and to explore how researchers could move towards a more sensitive and standard sampling method.

Immunization against Genital Herpes with a Vaccine Virus That has Defects in Productive and Latent Infection

da Costa, Xavier J.; Jones, Cheryl A.; Knipe, David M.

1999-06-01

An effective vaccine for genital herpes has been difficult to achieve because of the limited efficacy of subunit vaccines and the safety concerns about live viruses. As an alternative approach, mutant herpes simplex virus strains that are replication-defective can induce protective immunity. To increase the level of safety and to prove that replication was not needed for immunization, we constructed a mutant herpes simplex virus 2 strain containing two deletion mutations, each of which eliminated viral replication. The double-mutant virus induces protective immunity that can reduce acute viral shedding and latent infection in a mouse genital model, but importantly, the double-mutant virus shows a phenotypic defect in latent infection. This herpes vaccine strain, which is immunogenic but has defects in both productive and latent infection, provides a paradigm for the design of vaccines and vaccine vectors for other sexually transmitted diseases, such as AIDS.

Cox regression was employed to characterize survival while controlling for potential confounders in the study population.Women (n=27 had significantly poorer outcomes than men (n=198 in the statewide cohort (adjusted hazard ratio=2.31, 95% CI: 1.22 to 4.35, and a similar, non-significant trend was observed among university-based cases (n=17 women, 154 men. Secondary analyses suggested that this difference persisted over the course of the AIDS epidemic and was not attributable to differential antiretroviral therapy responses among men and women.The survival disadvantage of women compared to men should be confirmed and the mechanisms underlying this disparity elucidated. If this relationship is confirmed, targeted clinical and public health efforts might be directed towards screening, treatment, and support for women affected by neuro-AIDS.

Viruses tested included six HIV-1 and five HIV-2 isolates propagated in different cells, as well as infectious plasma from AIDS patients. The antiviral effect of anti-Tn MAbs occurred by specific binding of the MAb to the virus......; this binding was inhibitable by pure Tn antigen, and indications were found that this inhibition occurred at a pre-entry step.

This study assessed the preparedness of school health personnel to develop and deliver HIV/AIDS prevention education programmes for young people in China. A survey of 653 personnel working in secondary schools in 14 cities was conducted. More than 90% had basic knowledge of ways in which HIV can be transmitted, but knowledge of ways in which the virus is not transmitted needs improvement. Substantial numbers of teachers were not sure whether there was an effective preventive vaccine (42%) or did not know whether AIDS was a curable illness or not (32%). The great majority approved of AIDS prevention programmes in universities (98%) and secondary schools (91%), although fewer (58%) agreed that the topic was appropriate for primary schools. Currently, most classroom activities focuses on teaching facts about HIV/AIDS transmission, while less than half are taught about HIV/AIDS related discrimination and life skills to reduce peer pressure. Personnel with some prior training on HIV/ AIDS education (53%) had better factual knowledge, more tolerant attitudes and more confidence in teaching about HIV/AIDS than those without training. The majority of teachers indicated a need for more resource books, audiovisual products, expert guidance, school principal support and dissemination of national AIDS prevention education guidelines to schools.

Hospitalizations are an important indicator of healthcare quality and access for people with human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS). This study assesses hospitalization rates among people with HIV/AIDS in New York City. We performed a deterministic match between people in the New York City HIV surveillance registry alive as of 1 January 2013 and diagnosed with HIV as of 31 December 2013 and patient-level inpatient hospitalization records during 2013. Event-level data were analyzed to determine characteristics of and reasons for hospitalizations. Primary diagnoses were classified using the International Classification of Diseases, Ninth Revision, Clinical Modification. We estimated hospitalization rates as the number of hospitalizations per 100 person-years for all causes, AIDS-defining illnesses, and non-AIDS-defining infections. Nearly one-fifth of hospitalizations were attributed to non-AIDS-defining infections, whereas AIDS-defining illness diagnoses were infrequent (3.6% of hospitalizations). Other common causes were cardiovascular (10.9%) and substance use (9.8%). The estimated all-cause hospitalization rate was 36.7 per 100 person-years. Higher all-cause hospitalization rates were observed among females (46.8 per 100 person-years), Black and Latino/Hispanic people (41.8 and 39.5 per 100 person-years, respectively), people living in high-poverty neighborhoods (47.4 per 100 person-years), and people with a history of injection drug use (74.9 per 100 person-years). The estimated AIDS-defining illness and non-AIDS-defining infection hospitalization rates were 1.3 and 7.2 per 100 person-years, respectively. People with HIV in New York City were frequently hospitalized. While AIDS-defining illnesses were relatively rare, non-AIDS-defining infection hospitalizations were more common. Disparities in hospitalization rates indicate a need for targeted improved primary care and comorbid disease management. © The Author 2017

What can a teacher do with a cellphone? Using participatory visual research to speak back in addressing HIV&AIDS

Full Text Available The ubiquity of cellphones in South Africa, a country ravaged by HIV and AIDS, makes cellphones an easily accessible tool to use in participatory approaches to addressing HIV (Human Immunodeficiency Virus and AIDS (Acquired Immunodeficiency Syndrome issues, particularly in school contexts. In this article we explore a participatory visual approach undertaken with a group of rural teachers, to uncover and address HIV and AIDS related issues. Drawing on our experience in using participatory video, we used cellphones to produce cellphilms about youth and risk in the context of HIV and AIDS. Noting that the teachers brought highly didactic and moralistic tones into the cellphilms, we devised a "speaking back" approach to encourage reflection and an adjustment to their approaches when addressing HIV and AIDS issues with learners. We draw on the example of condom use in one cellphilm to demonstrate how a "speaking back" pedagogy can encourage reflection and participatory analysis, and contribute to deepening an understanding of how teachers might work with youth and risk in the context of HIV and AIDS.

Rationale for an HIV / AIDS prevention and mitigation strategy for Africa: combatting the multisectoral impact of the epidemic.

Unlike most infectious diseases in Africa, HIV/AIDS affects the urban elite as well as the rural poor, and generally during their most economically productive years. An increase in deaths among young adults of the magnitude predicted is likely to have substantial adverse effects on economic, political, and military/security stability throughout Africa. AIDS is causing increased stress on fragile African economic infrastructures as labor productivity declines, particularly in agricultural, labor-dependent economies. AIDS is causing obstacles to trade, foreign investment and tourism. Health systems and social coping mechanisms already are overburdened. High rates of HIV infection among police and military personnel threaten internal security. Furthermore, the demobilization of military forces in Africa may exacerbate the epidemic when HIV-infected soldiers return home and spread the virus. This presentation will illustrate why African AIDS Programs must be expanded to mitigate the multisectoral impact of the epidemic while preserving its spread.

To study the characteristics of traditional Chinese medicine (TCM) syndrome factors of patients from different areas of China with human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS). A cross-sectional investigation study was conducted in Henan, Guangdong and Yunnan Provinces and Xinjiang Uygur Autonomous Region of China from October 2008 to August 2010. Based on literature review and expert opinion, a clinical questionnaire of TCM syndromes was drawn up. This survey was carried out after the investigators were professionally trained. Wenfeng III Auxiliary Diagnosis and Treat System of TCM was used to analyze the frequencies of AIDS patients' signs and symptoms with scores above 70 of syndrome factors respectively. Based on this work, syndrome factors of AIDS were analyzed in different areas. There were 608 HIV/AIDS cases investigated from October 2008 to August 2010 in total; among them, 276 cases were from Henan, 126 cases from Guangdong, 120 cases from Xinjiang and 86 cases from Yunnan. The results of syndrome factor analysis indicated that the syndromes of four provinces were similar. HIV/AIDS patients in the four areas exhibited qi deficiency, blood deficiency, yin deficiency, yang deficiency, dampness, phlegm, qi stagnation and essence deficiency syndromes. Patients in each area also had their own characteristics, such as that the scores of dampness of Guangdong and yin deficiency of Xinjiang were higher than the other syndromes, whereas the scores of Henan Province were higher than the other areas. AIDS patients had higher scores of syndromes than HIV-infected patients. HIV/AIDS patients from different areas had similar syndrome elements. The theory of "AIDS toxin injuring primordial qi" can sum up the TCM etiology and pathogenesis of HIV/AIDS.

study period, and CRF01-AE and CRF07-BC intersubtype recombinant forms were predominant; however, a declining trend in the proportion of HIV-1 CRF01-AE recombinant virus and a significant rise in the proportion of HIV-1 CRF07-BC recombinant virus were observed. Over 90% HIV inhibition was found in all cases receiving antiretroviral therapy during the period from 2011 to 2015, indicating a low prevalence of HIV drug resistance. An increasing trend is still observed in the HIV/AIDS epidemics in Fujian Province, southeastern China. However, the epidemiological pattern of HIV/AIDS has recently changed in the province, and effective control interventions targeting the shift in the epidemiological features of HIV/AIDS should therefore be implemented to control the spread of the epidemic.

Changing patterns of human immunodeficiency virus-associated neuropathology

Directory of Open Access Journals (Sweden)

Gray Francoise

2007-01-01

Full Text Available This paper describes the evolution of the pathogenic concepts associated with the infection by the human immunodeficiency virus (HIV, with emphasis to the pathology of the nervous system. Although the first description of damage to the nervous system in the acquired immunodeficiency syndrome (AIDS only appeared in 1982, the dramatic diffusion of the epidemic worldwide, as well as the invariably rapidly fatal outcome of the disease before the introduction of efficient treatment, generated from the beginning an enormous amount of research and re-thinking on a number of pathogenetic concepts. Less than 25 years after the first autopsy series on AIDS patients were published and the virus responsible for AIDS was identified, satisfactory definition and classification of a number of neuropathological complications of HIV infection have been established. This has led to the establishment of accurate clinical and biological diagnosis of the main neurological complications of the disease, which remain a major cause of disability and death in patients. Clinical and experimental studies have provided essential insight into the pathogenesis of CNS lesions and the natural history of the disorder. The relatively recent introduction of effective antiretroviral therapy in 1995-6 dramatically improved the course of prognosis of HIV disease. However, there remain a number of unsolved pathogenetic issues, the most puzzling of which remains the precise mechanism of neuronal damage underlying the specific HIV-related cognitive disorder (HIV-dementia. In addition, although antiretroviral therapy has changed the course of neurological complications, new issues have emerged, such as the lack of improvement or even paradoxical deterioration of the neurological status in treated patients. Interpretation of these complications remains largely speculative, partly because of the small number of neuropathological studies related to the beneficial consequence of this

Australia to fund HIV / AIDS projects in Southeast Asia.

Australia will fund 23 new HIV-AIDS projects in Southeast Asian countries, the government announced. "Asia is predicted to be the major growth area for human immunodeficiency virus (HIV) infections over the next decade, " Minister for Development Cooperation Gordon Bilney said. "These projects, worth some $4.35 million over three years, will help meet the challenge of preventing the spread of the disease in the region." The projects--in Thailand, Vietnam, the Philippines, Indonesia, Malaysia and Cambodia--emphasize education and prevention activities as well as programs which focus on the care and support of people living with HIV, Bilney said. He also said a variety of Australian and overseas organizations will implement the projects, many of which will feature the significant involvement of communities at risk and people with HIV. "It is in keeping with the fundamental spirit of the aid program that we should seek to share this expertise with our neighbors in the region." Bilney said one Australian success story--the creative "Streetwize comics" (publications in Australia which help street kids and under privileged kids understand HIV/AIDS problems)--will be piloted in Vietnam in conjunction with the Vietnam Youth Federation. He said Vietnamese staff will be trained in the production of a series of bilingual mini-comics on HIV-AIDS prevention for youth. "This project will receive funding of $187,500 over three years," Bilney said. Bilney said the projects would help minimize the individual and social impact of the epidemic in the targeted countries. full text

The immunology of Zika Virus [version 1; referees: 2 approved

Full Text Available Zika virus (ZIKV was initially thought to cause only mild, self-limiting symptoms. However, recent outbreaks have been associated with the autoimmune disease Guillain-Barré syndrome and causally linked to a congenital malformation known as microcephaly. This has led to an urgent need for a safe and effective vaccine. A comprehensive understanding of the immunology of ZIKV infection is required to aid in the design of such a vaccine. Whilst details of both innate and adaptive immune responses to ZIKV are emerging, further research is needed. As immunopathogenesis has been implicated in poor outcomes following infection with the related dengue virus, identification of cross-reactive immune responses between flaviviruses and the impact they may have on disease progression is also of high importance.

Seroprevalence of Infections with Dengue, Rift Valley Fever and Chikungunya Viruses in Kenya, 2007.

Full Text Available Arthropod-borne viruses are a major constituent of emerging infectious diseases worldwide, but limited data are available on the prevalence, distribution, and risk factors for transmission in Kenya and East Africa. In this study, we used 1,091 HIV-negative blood specimens from the 2007 Kenya AIDS Indicator Survey (KAIS 2007 to test for the presence of IgG antibodies to dengue virus (DENV, chikungunya virus (CHIKV and Rift Valley fever virus (RVFV.The KAIS 2007 was a national population-based survey conducted by the Government of Kenya to provide comprehensive information needed to address the HIV/AIDS epidemic. Antibody testing for arboviruses was performed on stored blood specimens from KAIS 2007 through a two-step sandwich IgG ELISA using either commercially available kits or CDC-developed assays. Out of the 1,091 samples tested, 210 (19.2% were positive for IgG antibodies against at least one of the three arboviruses. DENV was the most common of the three viruses tested (12.5% positive, followed by RVFV and CHIKV (4.5% and 0.97%, respectively. For DENV and RVFV, the participant's province of residence was significantly associated (P≤.01 with seropositivity. Seroprevalence of DENV and RVFV increased with age, while there was no correlation between province of residence/age and seropositivity for CHIKV. Females had twelve times higher odds of exposure to CHIK as opposed to DENV and RVFV where both males and females had the same odds of exposure. Lack of education was significantly associated with a higher odds of previous infection with either DENV or RVFV (p <0.01. These data show that a number of people are at risk of arbovirus infections depending on their geographic location in Kenya and transmission of these pathogens is greater than previously appreciated. This poses a public health risk, especially for DENV.

Canine distemper virus commonly infects free-ranging, terrestrial mesopredators throughout the United States. Due to the immunosuppressive effects of the virus, concurrent opportunistic infections are also common. Among these, secondary systemic protozoal infections have been described in a number of species. We report an unusual presentation of necrotizing encephalitis associated withSarcocystissp in four raccoons and one skunk concurrently infected with canine distemper virus. Lesions were characterized by variably sized necrotizing cavitations composed of abundant mineral admixed with inflammatory cells and protozoa.Sarcocystissp was confirmed via immunohistochemistry using a monoclonal antibody toSarcocystis neurona The pathologic changes are similar to lesions in human AIDS patients infected withToxoplasma gondii. © The Author(s) 2015.

People infected with human immunodeficiency virus (HIV) have an increased risk of some malignancies, but little is known about the effects of infection on risk of cancers of the upper gastrointestinal tract. We evaluated the risks of different histologic and anatomic subtypes of carcinomas and non-Hodgkin lymphomas (NHLs) of the stomach and esophagus in people with acquired immunodeficiency syndrome (AIDS). We analyzed data from the HIV/AIDS Cancer Match Study, which links data collected from 1980 to 2007 for 16 US population-based HIV and AIDS and cancer registries. We compared risks of stomach and esophageal malignancies in people with AIDS (N = 596,955) with those of the general population using standardized incidence ratios (SIRs). We assessed calendar trends using Poisson regression. People with AIDS had increased risks of carcinomas of the esophagus (SIR, 1.69; 95% confidence interval [CI], 1.37-2.07; n = 95) and stomach (SIR, 1.44; 95% CI, 1.17-1.76; n = 96). Risk was increased for esophageal adenocarcinoma (SIR, 1.91; 95% CI, 1.31-2.70) and squamous cell carcinoma (SIR, 1.47; 95% CI, 1.10-1.92). People with AIDS had greater risks of carcinomas of the gastric cardia (SIR, 1.36; 95% CI, 0.83-2.11) and noncardia (SIR, 1.53; 95% CI, 1.12-2.05) than the general population. Although most stomach and esophageal NHLs that developed in people with AIDS were diffuse large B-cell lymphomas, these individuals also had an increased risk of stomach mucosa-associated lymphoid tissue lymphoma (SIR, 5.99; 95% CI, 3.19-10.2; n = 13). The incidence of carcinomas remained fairly constant over time, but rates of NHL decreased from 1980 to 2007 (P(trend) AIDS are at increased risk for developing esophageal and stomach carcinomas and NHLs. Although the incidence of NHL decreased from 1980 to 2007 as treatments for HIV infection improved, HIV-infected individuals face continued risks of esophageal and stomach carcinomas.

Adaptive evolution of simian immunodeficiency viruses isolated from two conventional progressor macaques with neuroaids

2008-01-01

Simian immunodeficiency virus infection of macaques may result in neuroAIDS, a feature more commonly observed in macaques with rapid progressive disease than in those with conventional disease. This is the first report of two conventional progressors (H631 and H636) with encephalitis in rhesus macaques inoculated with a derivative of SIVsmES43-3. Phylogenetic analyses of viruses isolated from the cerebral spinal fluid (CSF) and plasma from both animals demonstrated tissue compartmentalization. Additionally, virus from the central nervous system (CNS) was able to infect primary macaque monocyte-derived macrophages more efficiently than virus from plasma. Conversely, virus isolated from plasma was able to replicate better in peripheral blood mononuclear cells than virus from CNS. We speculate that these viruses were under different selective pressures in their separate compartments. Furthermore, these viruses appear to have undergone adaptive evolution to preferentially replicate in their respective cell targets. Analysis of the number of potential N-linked glycosylation sites (PNGS) in gp160 showed that there was a statistically significant loss of PNGS in viruses isolated from CNS in both macaques compared to SIVsmE543-3. Moreover, virus isolated from the brain in H631, had statistically significant loss of PNGS compared to virus isolated from CSF and plasma of the same animal. It is possible that the brain isolate may have adapted to decrease the number of PNGS given that humoral immune selection pressure is less likely to be encountered in the brain. These viruses provide a relevant model to study the adaptations required for SIV to induce encephalitis.

Addressing Ebola-related stigma: lessons learned from HIV/AIDS.

HIV/AIDS and Ebola Virus Disease (EVD) are contemporary epidemics associated with significant social stigma in which communities affected suffer from social rejection, violence, and diminished quality of life. To compare and contrast stigma related to HIV/AIDS and EVD, and strategically think how lessons learned from HIV stigma can be applied to the current EVD epidemic. To identify relevant articles about HIV/AIDS and EVD-related stigma, we conducted an extensive literature review using multiple search engines. PubMed was used to search for relevant peer-reviewed journal articles and Google for online sources. We also consulted the websites of the World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), and the National Institutes of Health to retrieve up-to-date information about EVD and HIV/AIDS. Many stigmatizing attitudes and behaviors directed towards those with EVD are strikingly similar to those with HIV/AIDS but there are significant differences worthy of discussion. Both diseases are life-threatening and there is no medical cure. Additionally misinformation about affected groups and modes of transmission runs rampant. Unlike in persons with EVD, historically criminalized and marginalized populations carry a disproportionately higher risk for HIV infection. Moreover, mortality due to EVD occurs within a shorter time span as compared to HIV/AIDS. Stigma disrupts quality of life, whether it is associated with HIV infection or EVD. When addressing EVD, we must think beyond the immediate clinical therapeutic response, to possible HIV implications of serum treatment. There are emerging social concerns of stigma associated with EVD infection and double stigma associated with EVD and HIV infection. Drawing upon lessons learned from HIV, we must work to empower and mobilize prominent members of the community, those who recovered from the disease, and organizations working at the grassroots level to disseminate clear and accurate

Verificou-se que esta doença afeta muito frequentemente os pacientes com AIDS e pode ser a primeira manifestação desta síndrome. O objetivo deste trabalho é o de comparar o resultado dos exames das amostras do LCR inicial na meningencefalite por criptococo entre pacientes com e sem AIDS. Este trabalho é baseado no estudo de 41 pacientes com neurocriptococose sem AIDS e de 23 pacientes com neurocriptococose e AIDS. Este estudo permitiu verificar que a reação inflamatória, no sistema nervoso, quando presente, foi de menor intensidade nos pacientes com AIDS; a reação inflamatória esteve presente em todos os pacientes sem AIDS e ausente em 21,7% dos pacientes com AIDS; o quadro inflamatório crônico, semelhante ao da meningencefalite tuberculosa, clássico nas meningencefalites por criptococo, ocorreu raramente nos pacientes com AIDS; em média, o número de criptococos no LCR foi maior nos pacientes com AIDS; pode ser feito diagnóstico presuntivo da AIDS quando o criptococo estiver presente no LCR que não apresenta alterações citológicas e bioquímicas.Neurocryptococcosis was a rare nervous system infection. With the rising number of patients with AIDS it became a very frequent disease. This infection is supposed to infect patients with some kind of immunodeficiency and the CSF alterations often simulate tuberculous meningitis. The purpose of this research was to compare the CSF changes in AIDS and non-AIDS patients with meningoencephalitis caused by Cr. neoformans. There were analysed 41 CSF samples from non-AIDS patients with neurocryptococcosis and 23 CSF samples from AIDS patients with neurocryptococcosis. The results of this research allowed to conclude that the inflammatory changes in the CSF from AIDS patients showed a lower intensity compared to those non-AIDS patients. These results showed as well, that the CSF samples from non-AIDS

Modeling HIV transmission and AIDS in the united states

Hethcote, Herbert W

1992-01-01

The disease that came to be called acquired immunodeficiency syndrome (AIDS) was first identified in the summer of 1981. By that time, nearly 100,000 persons in the United States may have been infected with human immunodeficiency virus (HIV). By the time the routes of transmission were clearly identified and HIV was established as the cause of AIDS in 1983, over 300,000 people may have been infected. That number has continued to increase, with approximately 1,000,000 Americans believed to be infected in 1991. The epidemic is of great public health concern because HlV is infectious, causes severe morbidity and death in most if not all of those infected, and often occurs in relatively young persons. In addition, the cost of medical care for a person with HIV disease is high, and the medical care needs of HIV-infected persons place a severe burden on the medical care systems in many areas. Understanding and controlling the HIV epidemic is a particularly difficult challenge. The long and variable period between H...

The Ebola and Marburg viruses are the sole members of the Filoviridae family of viruses. They are characterized by a long filamentous form that is unique in the viral world. Filoviruses are among the most virulent pathogens currently known to infect humans. They cause fulminating disease characterized by acute fever followed by generalized hemorrhagic syndrome that is associated with 90% mortality in the most severe forms. Epidemic outbreaks of Marburg and Ebola viruses have taken a heavy toll on human life in Central Africa and devastated large ape populations in Gabon and Republic of Congo. Since their discovery in 1967 (Marburg) and 1976 (Ebola), more than 2,300 cases and 1,670 deaths have been reported. These numbers pale in comparison with the burden caused by malnutrition or other infectious disease scourges in Africa such as malaria, cholera, AIDS, dengue or tuberculosis. However, due to their extremely high lethality, association with multifocal hemorrhaging and specificity to the African continent, these hemorrhagic fever viruses have given rise to great interest on the part not only of the international scientific community but also of the general public because of their perceived potential as biological weapons. Much research has been performed on these viruses and major progress has been made in knowledge of their ecology, epidemiology and physiopathology and in development of vaccine candidates and therapeutic schemes. The purpose of this review is to present the main developments in these particular fields in the last decade.

Of the first 395 attendees at the AIDS clinic in Jerusalem, 32% were homo/bisexuals, 4% i.v. drug abusers (IVDAs), 24% persons with minimal risk for AIDS and 38% were persons having no risk. Human immunodeficiency virus (HIV) antibody rates were 7% for homosexuals, 29% for IVDAs, 1% for persons with minimal risk and 0% for persons at no risk. Israeli homosexuals had a significantly greater risk for HIV infection (9 of 35) if they had sexual contact with non-Israelis as compared with homosexuals who had contact with local partners only (0/91, P less than 0.001). The mean number of attendees per month increased by 431% during the 4 months following the first prime-time television program on AIDS. The largest mean increases occurred among persons at no risk (1 to 27.2), those with minimal risk (2.5 to 16.5), and among women (1.25 to 20.0). This report indicates that HIV infection among Israeli homosexuals has not yet reached U.S. proportions. It also shows that the TV program raised anxiety concerning AIDS among the general public, and probably encouraged the public to use HIV testing as part of a general health screening program.

Full Text Available A virus antigenic characterization methodology using an indirect method of antibody detection ELISA with virus-infected cultured cells as antigen and a micro virus neutralisation test using EIA (NT-EIA as an aid to reading were used for antigenic characterization of Jatobal (BeAn 423380. Jatobal virus was characterized as a Bunyaviridae, Bunyavirus genus, Simbu serogroup virus. ELISA using infected cultured cells as antigen is a sensitive and reliable method for identification of viruses and has many advantages over conventional antibody capture ELISA's and other tests: it eliminates solid phase coating with virus and laborious antigen preparation; it permits screening of large numbers of virus antisera faster and more easily than by CF, HAI, or plaque reduction NT. ELISA and NT using EIA as an aid to reading can be applicable to viruses which do not produce cytopathogenic effect. Both techniques are applicable to identification of viruses which grow in mosquito cells.A caracterização antigênica do vírus Jatobal (BeAn 423380 foi efetuada utilizando uma técnica de ELISA para deteccão de anticorpos que utiliza culturas celulares infectadas como antígeno e um micro teste de neutralização para vírus que utiliza o método imunoenzimático como auxiliar para a leitura dos resultados (NT-EIA.

We conducted a retrospective chart review of human immunodeficiency virus (HIV)-infected patients who died in 1995 and in 1999-2000. We found an increase in the proportion of patients who died from an illness that was not related to acquired immunodeficiency syndrome (AIDS). Although there was a decrease in the prevalence of AIDS-defining illnesses, >85% of patients died with CD4 counts of 50% of HIV-infected patients who died were not receiving HAART. AIDS-defining illnesses continue to be a major cause of mortality in the HAART era in populations where access to care and adherence to HAART is limited.

Objective: To reveal the prevalence and the related factors of hepatitis B (HepB) virus infection among HIV/AIDS patients. Methods: We conducted a cross-sectional study in two HIV clinics, affiliated to local Centers of Disease Control and Prevention in Guangxi Zhuang Autonomous Regional. A face-to-face interview, with questionnaire was conducted to collect information on socio-demographic characteristics, drug use, and sexual behavior. Blood samples were used to test HBsAg. χ (2) test or Fisher's exact test and unconditional logistic regression models were used to identify the influencing factors. Results: The prevalence of HBV and HIV co-infection was 13.85% (113/816). Results from multivariate logistic regression analyses showed that age (25-45), family history of HBV and history of HepB vaccination were independent influencing factors for HBV and HIV coinfection, with OR (95% CI ) as 1.738 (1.031-2.931), 2.898 (1.678-5.005) and 1.744 (1.052-2.892), respectively. Conclusion: The prevalence of HBV among HIV/AIDS patients was significantly higher than that in general population. HIV/AIDS patients aged between 25 and 45 and with family history of HBV were more likely to be infected with HBV, while HepB vaccination was associated with the reduction of HIV/HBV coinfection. Specific comprehensive prevention and treatment programs on HIV/AIDS patients need to be set up.

In this study, the authors have investigated the potential mechanisms responsible for the loss of human immunodeficiency virus type 1 (HIV-1)-specific cytolytic activity in the advanced stages of HIV-1 infection. They have demonstrated that HIV-1-specific cytotoxic T lymphocytes are predominantly contained within the CD8 + DR + subset. Furthermore, they have shown by a redirected killing assay that there is a dichotomy between HIV-1-specific cytolytic activity and broad cytolytic potential since the cytolytic machinery of CD8 + DR + cells is still functioning even in patients with AIDS who have lost their HIV-1-specific cytolytic activity. In addition, by comparative analysis of these two types of cytolytic activity over time they have demonstrated a progressive loss of HIV-1-specific cytolytic activity in the advanced stages of the disease, whereas the cytolytic potential remained unchanged regardless of the clinical stage. On the basis of these results, they propose that the loss of HIV-1-specific cytolytic activity in HIV-1-infected individuals may result at least in part from a progressive decrease in the pool of HIV-1-specific cytotoxic T lymphocytes belonging to the CD8 + DR + subset whose ability to expand has been impaired

At present there is limited experience with MR imaging in infectious and inflammatory diseases of the brain. The purpose of this study was to compare the diagnostic sensitivity of MR imaging and CT in presumed or proved cases of cerebral infection, inflammation, or intracranial manifestation of the acquired immunodeficiency syndrome (AIDS). Third-generation CT scanners were used to obtain plain and Gd-DTPA-enhanced scans. A 0.5-T Magnetom MR imager was used to obtain plain and contrast-enhanced T1-weighted, T1/T2-weighted, and T2-weighted images with spin-echo and fast low-angle shot (FLASH) techniques. Group 1 (immunocompetent) included 35 patients (63 examinations), group 2 (AIDS), 78 (115 examinations). Diagnoses in both groups yielded a wide range of etiologies (e.g., group 1: sarcoidosis, herpes encephalitis, meningitis, neurocysticercosis, Jakob-Creutzfeldt disease, tuberculosis, virus encephalitis; group 2: toxoplasmosis, progressive diffuse leukoencephalopathia (PDL), progressive multifocal leukoencephalopathia (PML), meningitis

An estimated 35 million people are infected with HIV worldwide. Anti-retroviral therapy (ART) has reduced the morbidity and mortality of HIV-infected patients but efficacy requires strict adherence and the treatment is not curative. Most importantly, the emergence of drug-resistant virus strains and drug toxicity can restrict the long-term therapeutic efficacy in some patients. Therefore, novel treatment strategies that permanently control or eliminate the virus and restore the damaged immune system are required. Gene therapy against HIV infection has been the topic of intense investigations for the last two decades because it can theoretically provide such a durable anti-HIV control. In this review we discuss two major gene therapy strategies to combat HIV. One approach aims to kill HIV-infected cells and the other is based on the protection of cells from HIV infection. We discuss the underlying molecular mechanisms for candidate approaches to permanently block HIV infection, including the latest strategies and future therapeutic applications. Hematopoietic stem cell-based gene therapy for HIV/AIDS may eventually become an alternative for standard ART and should ideally provide a functional cure in which the virus is durably controlled without medication. Recent results from preclinical research and early-stage clinical trials support the feasibility and safety of this novel strategy.

Rift Valley fever virus (RVFV; Bunyaviridae; Phlebovirus) is an emerging human and veterinary pathogen causing acute hepatitis in ruminants and has the potential to cause hemorrhagic fever in humans. We report a three-dimensional reconstruction of RVFV vaccine strain MP-12 (RVFV MP-12) by cryo-electron microcopy using icosahedral symmetry of individual virions. Although the genomic core of RVFV MP-12 is apparently poorly ordered, the glycoproteins on the virus surface are highly symmetric and arranged on a T = 12 icosahedral lattice. Our RVFV MP-12 structure allowed clear identification of inter-capsomer contacts and definition of possible glycoprotein arrangements within capsomers. This structure provides a detailed model for phleboviruses, opens new avenues for high-resolution structural studies of the bunyavirus family, and aids the design of antiviral diagnostics and effective subunit vaccines.

gene exchange between influenza A and B viruses is not well understood. Nucleotides comprising the coding termini of each influenza A virus gene segment are required for specific segment incorporation during budding. Whether influenza B virus shares a similar selective packaging strategy or if packaging signals prevent intertypic reassortment remains unknown. Here, we provide evidence suggesting a similar mechanism of influenza B virus genome packaging. Furthermore, by appending influenza A virus packaging signals onto influenza B virus segments, we rescued recombinant influenza A/B viruses that could reassort in vitro with another influenza A virus. These findings suggest that the divergent evolution of packaging signals aids with the speciation of influenza A and B viruses and is in part responsible for the lack of intertypic viral reassortment.

Full Text Available The problem of HIV/AIDS was sort of a fairy tale and mere information till the immunological disorder was scientifically confirmed. Today, HIV/AIDS has continued to be a serious international health concern, and sub-Saharan Africa remains the most affected region. Over 25.6 million persons are currently living with HIV in sub-Saharan Africa. This accounts for two-thirds of the recent overall world HIV infections and more than 70 percent of all AIDSrelated deaths. In 2015, Eastern and Southern Africa had about 7.1% adult HIV prevalence rate (about 19 million HIV patients, while Western and Central Africa accounted for about 2.2% (about 6.5 million HIV patients. Few countries now boast of numerous signs of gradual to moderate declines in HIV occurrence. However, HIV prevalence rate has continued to increase in countries like Lesotho (22.7%, Botswana (22.2% and South Africa (19.2%. The nature, procedure and result of the scourge in this region have been fashioned by a mind-boggling interaction of traditional, behavioural, social and material factors. Even if there are notably strong prevention, treatment and care programmes, too many sexual partners are engaging in risky sexual practices. The aim of this article is to discuss the current trends of HIV/AIDS in sub-Saharan Africa, the factors that might have contributed to high prevalence of the virus in the region, the effect of the HIV/AIDS scourge, the prevention programmes and the way forward.

Virus-Vectored Influenza Virus Vaccines

Tripp, Ralph A.; Tompkins, S. Mark

2014-01-01

Despite the availability of an inactivated vaccine that has been licensed for >50 years, the influenza virus continues to cause morbidity and mortality worldwide. Constant evolution of circulating influenza virus strains and the emergence of new strains diminishes the effectiveness of annual vaccines that rely on a match with circulating influenza strains. Thus, there is a continued need for new, efficacious vaccines conferring cross-clade protection to avoid the need for biannual reformulation of seasonal influenza vaccines. Recombinant virus-vectored vaccines are an appealing alternative to classical inactivated vaccines because virus vectors enable native expression of influenza antigens, even from virulent influenza viruses, while expressed in the context of the vector that can improve immunogenicity. In addition, a vectored vaccine often enables delivery of the vaccine to sites of inductive immunity such as the respiratory tract enabling protection from influenza virus infection. Moreover, the ability to readily manipulate virus vectors to produce novel influenza vaccines may provide the quickest path toward a universal vaccine protecting against all influenza viruses. This review will discuss experimental virus-vectored vaccines for use in humans, comparing them to licensed vaccines and the hurdles faced for licensure of these next-generation influenza virus vaccines.

Lapidot, Moshe; Legg, James P; Wintermantel, William M; Polston, Jane E

2014-01-01

Whiteflies are a key pest of crops in open-field production throughout the tropics and subtropics. This is due in large part to the long and diverse list of devastating plant viruses transmitted by these vectors. Open-field production provides many challenges to manage these viruses and in many cases adequate management has not been possible. Diseases caused by whitefly-transmitted viruses have become limiting factors in open-field production of a wide range of crops, i.e., bean golden mosaic disease in beans, tomato yellow leaf curl disease in tomato, cassava mosaic disease and cassava brown streak disease in cassava, and cotton leaf crumple disease in cotton. While host resistance has proven to be the most cost-effective management solution, few examples of host resistance have been developed to date. The main strategy to limit the incidence of virus-infected plants has been the application of insecticides to reduce vector populations aided to some extent by the use of selected cultural practices. However, due to concerns about the effect of insecticides on pollinators, consumer demand for reduced pesticide use, and the ability of the whitefly vectors to develop insecticide-resistance, there is a growing need to develop and deploy strategies that do not rely on insecticides. The reduction in pesticide use will greatly increase the need for genetic resistance to more viruses in more crop plants. Resistance combined with selected IPM strategies could become a viable means to increase yields in crops produced in open fields despite the presence of whitefly-transmitted viruses.

Full Text Available The lentiviral envelope glycoproteins (Env mediate virus entry by interacting with specific receptors present at the cell surface, thereby determining viral tropism and pathogenesis. Therefore, Env incorporation into the virions formed by assembly of the viral Gag polyprotein at the plasma membrane of the infected cells is a key step in the replication cycle of lentiviruses. Besides being useful models of human immunodeficiency virus (HIV infections in humans and valuable tools for developing AIDS therapies and vaccines, simian and feline immunodeficiency viruses (SIV and FIV, respectively are relevant animal retroviruses; the study of which provides important information on how lentiviral replication strategies have evolved. In this review, we discuss the molecular mechanisms underlying the incorporation of the SIV and FIV Env glycoproteins into viral particles.

Executive summary of the Consensus Document of GeSIDA and Spanish Secretariat for the National Plan on AIDS on combined antiretroviral treatment in adults infected by the human immunodeficiency virus (January 2013).

Science.gov (United States)

2013-11-01

In the present update of the guidelines, a starting combination antiretroviral treatment (cART) is recommended in symptomatic patients, in pregnant women, in serodiscordant couples with a high risk of transmission, in patients co-infected with hepatitis B virus requiring treatment, and in patients with HIV-related nephropathy. Guidelines on cART are included in the event of a concurrent diagnosis of HIV infection with an AIDS-defining event. In asymptomatic naïve patients, cART is recommended if the CD4(+) lymphocyte count is 500cells/μL, cART can be delayed, although it may be considered in patients with liver cirrhosis, chronic infection due to hepatitis C virus, high cardiovascular risk, plasma viral load (PVL) >10(5)copies/mL, CD4(+) lymphocyte percentage 55 years. cART in naïve patients requires a combination of 3 drugs, and its aim is to achieve undetectable PVL. Treatment adherence plays a key role in sustaining a favorable response. cART can, and should be, changed if virological failure occurs, in order to return to undetectable PVL. Approaches to cART in acute HIV infection, in women, in pregnancy, in tuberculosis, and post-exposure prophylaxis are also examined. Copyright © 2013 Elsevier España, S.L. All rights reserved.

Homeless gay and bisexual (G/B) young men have multiple risk factors that increase their risk of contracting hepatitis B virus (HBV) and human immunodeficiency virus (HIV). This study used baseline information from structured instruments to assess correlates of knowledge to HIV and HBV infection from 267 young (18-39 year old) G/B active methamphetamine, cocaine, and crack-using homeless men enrolled in a longitudinal trial. The study is designed to reduce drug use and improve knowledge of hepatitis and HIV/AIDS in a community center in Hollywood, California. Regression modeling revealed that previous hepatitis education delivered to G/B men was associated with higher levels of HIV/AIDS and hepatitis knowledge. Moreover, higher HIV/AIDS knowledge was associated with combining sex and drinking alcohol. Associations with hepatitis B knowledge was found among G/B men who were engaging in sex while under the influence of marijuana, who were receiving support from non-drug users, and who had been homeless in the last 4 months. Although being informed about HIV/AIDS and hepatitis did not preclude risky sexual and drug use behavior, knowledge about the dangers of concurrent sex with substance use is important. As higher levels of knowledge of hepatitis was associated with more moderate drug use, early access to testing and teaching harm reduction strategies remain critical to reduce exposure and infection of HBV and HIV in this population.

Combinatorial RNA-based gene therapy for the treatment of HIV/AIDS.

Chung, Janet; DiGiusto, David L; Rossi, John J

2013-03-01

HIV/AIDS continues to be a worldwide health problem and viral eradication has been an elusive goal. HIV+ patients are currently treated with combination antiretroviral therapy (cART) which is not curative. For many patients, cART is inaccessible, intolerable or unaffordable. Therefore, a new class of therapeutics for HIV is required to overcome these limitations. Cell and gene therapy for HIV has been proposed as a way to provide a functional cure for HIV in the form of a virus/infection resistant immune system. In this review, the authors describe the standard therapy for HIV/AIDS, its limitations, current areas of investigation and the potential of hematopoietic stem cells modified with anti-HIV RNAs as a means to affect a functional cure for HIV. Cell and gene therapy for HIV/AIDS is a promising alternative to antiviral drug therapy and may provide a functional cure. In order to show clinical benefit, multiple mechanisms of inhibition of HIV entry and lifecycle are likely to be required. Among the most promising antiviral strategies is the use of transgenic RNA molecules that provide protection from HIV infection. When these molecules are delivered as gene-modified hematopoietic stem and progenitor cells, long-term repopulation of the patient's immune system with gene-modified progeny has been observed.

We report on a 8-month-old boy with AIDS, born of an asymptomatic mother with positive HTLV-III serology. He was hospitalized in the Intensive Care Unit because of anemia, fever and hepatosplenomegaly. Chest X-ray showed pneumonia and subsquent blood cultures were positive for Candida albicans. After 3 days of Amphotericine B treatment, the patient was transferred to Infectious Disease Department. After 30 days of hospitalization, the patient developed a rapid neurological impairment evolving into coma. CT scan showed a round, ring-shaped low density lesion with hyperdense and enhancing haemorragic centre in the left basal ganglia and a smaller hypodense lesion on the right. There was also evidence of cortical atrophy and mild ventricular dilatation. Such lesions are more commonly described in children with AIDS and congenital cytomegalic inclusion virus (CMV) encephalitis. In this case toxoplasma cysts were shown microscopically reinforcing the contention that in patients with AIDS, toxoplasma gondii infection may occur with atypical manifestation. (orig.).

We report on a 8-month-old boy with AIDS, born of an asymptomatic mother with positive HTLV-III serology. He was hospitalized in the Intensive Care Unit because of anemia, fever and hepatosplenomegaly. Chest X-ray showed pneumonia and subsquent blood cultures were positive for Candida albicans. After 3 days of Amphotericine B treatment, the patient was transferred to Infectious Disease Department. After 30 days of hospitalization, the patient developed a rapid neurological impairment evolving into coma. CT scan showed a round, ring-shaped low density lesion with hyperdense and enhancing haemorragic centre in the left basal ganglia and a smaller hypodense lesion on the right.

African American women, including adolescents and adults, are disproportionately affected by the transmission of Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS). HIV/AID is a health disparity issue for African American females in comparison to other ethnic groups. According to data acquired from 33 states in 2005, 64% of women who have HIV/ AIDS are African American women. It is estimated that during 2001-2004, 61% of African Americans under the age of 25 had been living with HIV/AIDS. This article is an analytical review of the literature emphasizing sexual assertiveness of African American women and the gap that exists in research literature on this population. The multifaceted model of HIV risk posits that an interpersonal predictor of risky sexual behavior is sexual assertiveness. The critical themes extracted from a review of the literature reveal the following: (a) sexual assertiveness is related to HIV risk in women, (b) sexual assertiveness and sexual communication are related, and (c) women with low sexual assertiveness are at increased risk of HIV As a result of this comprehensive literature, future research studies need to use models in validating sexual assertiveness interventions in reducing the risk of HIV/AIDS in African American women. HIV/AIDs prevention interventions or future studies need to target reducing the risk factors of HIV/AIDS of African Americans focusing on gender and culture-specific strategies.

The Difficulties of Feeling: The Role of Emotions in the Stigmatization of HIV/AIDS

Full Text Available The human immunodeficiency virus (HIV and the acquired immunodeficiency syndrome (AIDS have been a source of stigma for people who live with the disease. This stigmatization has been frequently studied from the perspective of stigmatizing agents focusing on opinions. This focus has systematically avoided exploring the role of emotions in the stigmatization process. We carried out this study in order to identify the role of emotions in the process of stigmatization of the people living with HIV and AIDS (PLWHA by health professionals. In order to achieve this objective we implemented an exploratory and qualitative design using in-depth semi-structured interviews. The sample consisted of 80 health professionals and health profession students from the following specialties: psychology, social work, medicine and nursing. The results reflected the existence of emotions associated to HIV/AIDS such as pity, compassion, disgust, and fear. Participants expressed the need to control their emotions when interacting with PLWHA. The results point to the need to explore factors that mediate emotions, such as the social context in which they are manifested and before whom they are revealed. This is a vital step in order to better understand the stigma surrounding HIV/AIDS. URN: urn:nbn:de:0114-fqs060428

With the first case of Human Immunodeficiency Virus infection/Acquired Immunodeficiency Syndrome (HIV/AIDS) identified in 1986, the management of HIV/AIDS in Nigeria has evolved through the years. The emergency phase of the HIV/AIDS program, aimed at containing the HIV/AIDS epidemic within a short time frame, was carried out by international agencies that built structures separate from hospitals' programs. It is imperative that Nigeria shifts from the previous paradigm to the concept of Commonization of HIV to achieve sustainability. Commonization ensures that HIV/AIDS is seen as a health condition like others. It involves making HIV services available at all levels of healthcare. Excellence & Friends Management Consult (EFMC) undertook this process by conducting HIV tests in people's homes and work places, referring infected persons for treatment and follow up, establishing multiple HIV testing points and HIV services in private and public primary healthcare facilities. EFMC integrated HIV services within existing hospital care structures and trained all healthcare workers at all supported sites on HIV/AIDS prevention, care and treatment modalities. Commonization has improved the uptake of HIV testing and counseling and enrolment into HIV care as more people are aware that HIV services are available. It has integrated HIV services into general hospital services and minimized the cost of HIV programming as the existing structures and personnel in healthcare facilities are utilized for HIV services. Commonization of HIV services i.e. integrating HIV care into the existing fabric of the healthcare system, is highly recommended for a sustainable and efficient healthcare system as it makes HIV services acceptable by all.

The National AIDS Committee was formed in 1985 to develop and support policies that prevent transmission of human immunodeficiency virus (HIV). In 1990, the Institute of Epidemiology, Disease Control and Research in the Ministry of Health began sero-surveillance for AIDS/HIV infection. Convenience sampling was conducted among prisoners, sailors, truckers, antenatal attendees, repatriated Bangladeshi workers, and brothel-based prostitutes in Dhaka. In 1994, commercial sex workers in other high-risk areas were included in surveillance activities. Among over 75,700 HIV tests through 1998, 119 have been confirmed positive for HIV. While the cumulative HIV prevalence rate was only 1.5/1,000 tests, it was significantly higher among men (p women. The rates among men were as high as 28/1,000 tests in 1996 and 21/1,000 tests in 1997. Almost 50% of the reported HIV cases are from cities on the border of India and Myanmar. It is anticipated that HIV transmission will increase further given the high prevalence of risk behaviors, core high-risk groups, and extreme poverty.

Feline immunodeficiency virus (FIV) causes AIDS in the domestic cat (Felis catus) but has not been explicitly associated with AIDS pathology in any of the eight free-ranging species of Felidae that are endemic with circulating FIV strains. African lion (Panthera leo) populations are infected with lion-specific FIV strains (FIVple), yet there remains uncertainty about the degree to which FIV infection impacts their health. Reported CD4+ T-lymphocyte depletion in FIVple-infected lions and anecdotal reports of lion morbidity associated with FIV seroprevalence emphasize the concern as to whether FIVple is innocuous or pathogenic. Here we monitored clinical, biochemical, histological and serological parameters among FIVple-positive (N=47) as compared to FIVple-negative (N=17) lions anesthetized and sampled on multiple occasions between 1999 and 2006 in Botswana. Relative to uninfected lions, FIVple-infected lions displayed a significant elevation in the prevalence of AIDS-defining conditions: lymphadenopathy, gingivitis, tongue papillomas, dehydration, and poor coat condition, as well as displaying abnormal red blood cell parameters, depressed serum albumin, and elevated liver enzymes and gamma globulin. Spleen and lymph node biopsies from free-ranging FIVple-infected lions (N=9) revealed evidence of lymphoid depletion, the hallmark pathology documented in immunodeficiency virus infections of humans (HIV-1), macaques, and domestic cats. We conclude that over time FIVple infections in free-ranging lions can lead to adverse clinical, immunological, and pathological outcomes in some individuals that parallel sequelae caused by lentivirus infection in humans (HIV), Asian macaques (SIV) and domestic cats (FIVfca).

ABSTRACT The H1 subtype of influenza A viruses (IAVs) has been circulating in swine since the 1918 human influenza pandemic. Over time, and aided by further introductions from nonswine hosts, swine H1 viruses have diversified into three genetic lineages. Due to limited global data, these H1 lineages were named based on colloquial context, leading to a proliferation of inconsistent regional naming conventions. In this study, we propose rigorous phylogenetic criteria to establish a globally consistent nomenclature of swine H1 virus hemagglutinin (HA) evolution. These criteria applied to a data set of 7,070 H1 HA sequences led to 28 distinct clades as the basis for the nomenclature. We developed and implemented a web-accessible annotation tool that can assign these biologically informative categories to new sequence data. The annotation tool assigned the combined data set of 7,070 H1 sequences to the correct clade more than 99% of the time. Our analyses indicated that 87% of the swine H1 viruses from 2010 to the present had HAs that belonged to 7 contemporary cocirculating clades. Our nomenclature and web-accessible classification tool provide an accurate method for researchers, diagnosticians, and health officials to assign clade designations to HA sequences. The tool can be updated readily to track evolving nomenclature as new clades emerge, ensuring continued relevance. A common global nomenclature facilitates comparisons of IAVs infecting humans and pigs, within and between regions, and can provide insight into the diversity of swine H1 influenza virus and its impact on vaccine strain selection, diagnostic reagents, and test performance, thereby simplifying communication of such data. IMPORTANCE A fundamental goal in the biological sciences is the definition of groups of organisms based on evolutionary history and the naming of those groups. For influenza A viruses (IAVs) in swine, understanding the hemagglutinin (HA) genetic lineage of a circulating strain aids

There are number of Non-Governmental Organisations (NGOs) in South Africa that use sport as a tool to respond to Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS), however, little is reported about the outcomes and impact of these programmes. The aim of this study is to contribute to a generic monitoring and evaluation framework by improving the options for the use of outcome indicators of sport-based HIV/AIDS awareness programmes of selected NGOs in South Africa. A qualitative method study was carried out with seven employees of five selected NGOs that integrate sport to deliver HIV/AIDS programmes in South Africa. The study further involved six specialists/experts involved in the field of HIV/AIDS and an official from Sport Recreation South Africa (SRSA). Multiple data collection instruments including desktop review, narrative systematic review, document analysis, one-on-one interviews and focus group interview were used to collect information on outcomes and indicators for sport-based HIV/AIDS awareness programmes. The information was classified according to the determinants of HIV/AIDS. The overall findings revealed that the sport-based HIV/AIDS awareness programmes of five selected NGOs examined in this study focus on similar HIV prevention messages within the key priorities highlighted in the current National Strategic Plan for HIV/AIDS, STIs and TB of South Africa. However, monitoring and evaluating outcomes of sport-based HIV/AIDS programmes of the selected NGOs remains a challenge. A need exists for the improvement of the outcome statements and indicators for their sport-based HIV/AIDS awareness programmes. This study proposed a total of 51 generic outcome indicators focusing on measuring change in the knowledge of HIV/AIDS and change in attitude and intention towards HIV risk behaviours. In addition, this study further proposed a total of eight generic outcome indicators to measure predictors of HIV risk behaviour. The selected

Shifting the burden: the private sector's response to the AIDS epidemic in Africa.

As the economic burden of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) increases in sub-Saharan Africa, allocation of the burden among levels and sectors of society is changing. The private sector has more scope to avoid the economic burden of AIDS than governments, households, or nongovernmental organizations, and the burden is being systematically shifted away from the private sector. Common practices that transfer the burden to households and government include pre-employment screening, reductions in employee benefits, restructured employment contracts, outsourcing of low skilled jobs, selective retrenchments, and changes in production technologies. Between 1997 and 1999 more than two-thirds of large South African employers reduced the level of health care benefits or increased employee contributions. Most firms also have replaced defined-benefit retirement funds, which expose the firm to large annual costs but provide long-term support for families, with defined-contribution funds, which eliminate risks to the firm but provide little for families of younger workers who die of AIDS. Contracting out previously permanent jobs is also shielding firms from benefit and turnover costs, effectively shifting the responsibility to care for affected workers and their families to households, nongovernmental organizations, and the government. Many of these changes are responses to globalization that would have occurred in the absence of AIDS, but they are devastating for the households of employees with HIV/AIDS. We argue that the shift in the economic burden of AIDS is a predictable response by business to which a deliberate public policy response is needed. Countries should make explicit decisions about each sector's responsibilities if a socially desirable allocation is to be achieved. PMID:12751421

Full Text Available The concepts, targets, tools, institutions and modes of operation of official development assistance have been overtaken by the pace of change in a world marked by the combined momentum of demography, technology and economic growth.Aid can however recover, as social consequences of the globalization call for new forms of regulation. It will then be necessary to modify and diversify our target-setting processes, to update operating procedures, and to find better ways of measuring policy implementation. Aid volumes will certainly continue to grow, and we must transform the way aid is financed. Public and private aid stakeholders must recognize the importance of these transformations and be ready to support them, by questioning the methods as well as the objectives of the policies they are implementing. Otherwise, they will severely impede the emergence of the policies we need if we are to build a better world.

A total of 23,40,000 blood samples were screened for the presence of antibodies against Human Immunodeficiency Virus (HIV) at various officially designated surveillance and diagnostic centers throughout the country, during the period of 12 years extending from 1986 to 1999. The reported positive cases screened before blood transfusion under the initiative launched in public sector hospitals during 1995 are also included in the total figure. A total of 1395 as symptomatic persons have been diagnosed and reported as HIV positive whereas 178 persons with signs and symptoms of full blown AIDS have been diagnosed. The tests were performed on selected categories of persons and include; persons with risky behavior, patients with sexually transmitted disease, professional blood donors, blood and blood product recipients intravenous drug injectors, patients with tuberculosis, women attending antenatal clinics, long distance drivers, and seaman. Apart from these identified groups, referred patients from the public and private hospitals, laboratories, clinics, nursing homes and HIV positive. The male to female ratio for HIV positive and AIDS cases as 7:1 and 8:1 respectively. Most of the cases acquired the disease through sexual contact including hetro, Homo and bisexual modes of transmission. Maximum numbers of the HIV positive individuals are between the age's 20-29 years. The data gives an overall prevalence rate of 0.07% which, although looking low, still deserves serious attention in view of system anomalies relating and under reporting and very long incubation period of the disease.

Addressing Ebola-related Stigma: Lessons Learned from HIV/AIDS

Directory of Open Access Journals (Sweden)

Mariam Davtyan

2014-11-01

Full Text Available Background: HIV/AIDS and Ebola Virus Disease (EVD are contemporary epidemics associated with significant social stigma in which communities affected suffer from social rejection, violence, and diminished quality of life. Objective: To compare and contrast stigma related to HIV/AIDS and EVD, and strategically think how lessons learned from HIV stigma can be applied to the current EVD epidemic. Methods: To identify relevant articles about HIV/AIDS and EVD-related stigma, we conducted an extensive literature review using multiple search engines. PubMed was used to search for relevant peer-reviewed journal articles and Google for online sources. We also consulted the websites of the World Health Organization (WHO, Centers for Disease Control and Prevention (CDC, and the National Institutes of Health to retrieve up-to-date information about EVD and HIV/AIDS. Results: Many stigmatizing attitudes and behaviors directed towards those with EVD are strikingly similar to those with HIV/AIDS but there are significant differences worthy of discussion. Both diseases are life-threatening and there is no medical cure. Additionally misinformation about affected groups and modes of transmission runs rampant. Unlike in persons with EVD, historically criminalized and marginalized populations carry a disproportionately higher risk for HIV infection. Moreover, mortality due to EVD occurs within a shorter time span as compared to HIV/AIDS. Conclusions: Stigma disrupts quality of life, whether it is associated with HIV infection or EVD. When addressing EVD, we must think beyond the immediate clinical therapeutic response, to possible HIV implications of serum treatment. There are emerging social concerns of stigma associated with EVD infection and double stigma associated with EVD and HIV infection. Drawing upon lessons learned from HIV, we must work to empower and mobilize prominent members of the community, those who recovered from the disease, and organizations

Many viruses have a lipid envelope derived from the host cell membrane that contributes much to the host specificity and the cellular invasion. This study puts forward a virus-inspired technology that allows targeted genetic delivery free from man-made materials. Genetic therapeutics, metal ions, and biologically derived cell membranes are nanointegrated. Vulnerable genetic therapeutics contained in the formed "nanogene" can be well protected from unwanted attacks by blood components and enzymes. The surface envelope composed of cancer cell membrane fragments enables host-specific targeting of the nanogene to the source cancer cells and homologous tumors while effectively inhibiting recognition by macrophages. High transfection efficiency highlights the potential of this technology for practical applications. Another unique merit of this technology arises from the facile combination of special biofunction of metal ions with genetic therapy. Typically, Gd(III)-involved nanogene generates a much higher T 1 relaxation rate than the clinically used Gd magnetic resonance imaging agent and harvests the enhanced MRI contrast at tumors. This virus-inspired technology points out a distinctive new avenue for the disease-specific transport of genetic therapeutics and other biomacromolecules. © 2018 WILEY-VCH Verlag GmbH & Co.

Full Text Available Human Immunodeficiency Virus type 1 (HIV-1 known to cause Acquired Immune Deficiency Syndrome (AIDS disease are divided into several subtypes (A, B, C, D, F, G, H, J, K and Circulating Recombinant Form (CRF. Different characteristics of subtype of the virus and its interaction with the host can affect the severity of the disease. This study was to analyze HIV-1 subtypes circulating in HIV/AIDS patients from the East Java region descriptively and to analyze its relationship with clinical stadiums of HIV/AIDS. Information from this research was expected to complement the data of mocular epidemiology of HIV in Indonesia. This study utilited blood plasma from patients who had been tested to be HIV positive who sected treatment to or were reffered to the Intermediate Care Unit of Infectious Disease (UPIPI Dr. Soetomo Hospital Surabaya from various area representing the East Java regions. Plasma was separated from blood samples by centrifugation for use in the the molecular biology examination including RNA extraction, nested PCR using specific primer for HIV gp120 env gene region, DNA purifying, DNA sequencing, and homology and phylogenetic analysis. Based on the nucleotide sequence of the HIV gp120 env gene, it was found that the most dominant subtypes in East Java were in one group of Circulating Recombinant Form (CRF that is CRF01_AE, CRF33_01B and CRF34_01B which was also found in Southeast Asia. In the phylogenetic tree, most of HIV samples (30 samples are in the same branch with CRF01_AE, CRF33_01B and CRF34_01B, except for one sample (HIV40 which is in the same branch with subtype B. HIV subtypes are associated with clinical stadiums (disease severity since samples from different stages of HIV disease have the same subtype.

The purpose of this cross-sectional study is to examine how personality traits such as sensation- seeking and impulsive decision-making affect Taiwanese college students' intentions to seek online information about sexually transmitted diseases (STDs) and human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS). Five hundred thirty-five (n = 535) junior and senior college students in Taiwan were recruited and completed self-report questionnaires. This study found high sensation-seekers were more likely to seek information about STDs and HIV/AIDS on the Internet than low sensation-seekers. Impulsive decision-makers were less likely than rational decision-makers to seek information about STDs and HIV/AIDS on the Internet. These findings suggest that personality needs to be considered as an exploratory factor which potentially influences intentions to seek STD and HIV/AIDS information on the Internet among Taiwanese college students.

The Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) pandemic has caused far-reaching effects in sub-Saharan Africa. The pandemic has effectively diminished the workforce, increased poverty rates, reduced agricultural productivity, and transformed the structure of many rural households. HIV/AIDS further strains the already fragile relationship between livelihood and the natural and social environments of these regions. Therefore, the objective of this review is to characterize the impact of HIV/AIDS on the environment and the social infrastructure of rural sub-Saharan Africa. There are many aspects of rural life that contribute to disease transmission of HIV/AIDS and that pose unique challenges to the population dynamics in sub-Saharan Africa. Widespread AIDS-related mortality has caused a decrease in population growth for many African countries. In turn, these alterations in population dynamics have resulted in a decrease in the percentage of prime-age working adults, as well as a gender disparity, whereby, females carry a growing burden of household responsibilities. There is a rising proportion of older adults, often females, who assume the role of provider and caretaker for other dependent family members. These changing dynamics have caused many to exploit their natural surroundings, adopting less sustainable land use practices and utilizing protected resources as a primary means of generating revenue.

In the absence of a cure or vaccine for acquired immune deficiency syndrome (AIDS) educational and social marketing efforts to reduce the transmission of Human T-lymphotropic type III/lymphadenopathy-associated virus (HTLV-III/LAV) are currently our best hope for controlling the disease. Since 1983, the Centers for Disease Control (CDC) has funded a series of research studies to determine whether education efforts can successfully motivate the adoption of key behaviors relevant to the control of a variety of sexually transmitted diseases (STDs). Analysis of the first two studies which are now completed, and preliminary data from a third study, have documented dramatic changes in behavior, knowledge, and attitudes among clients in inner-city public health clinics. The authors describe the principles and underlying assumptions that have guided the design of their STD initiatives, drawing special attention to the implications for AIDS health education efforts.

Paige, C Y; Johnson, M S

1997-10-01

This study examines social workers' perceptions of the needs of families coping with acquired immunodeficiency syndrome (AIDS). This research investigates the problems of family caregivers of children orphaned by human immunodeficiency virus (HIV)-related death of their parents. A qualitative semistructured interview format was used in a focus group of 18 social workers. Four questions were designed to assess family needs and resources, as well as to evaluate the social workers' perspectives of governmental policies affecting these families. A list of four problems and two recommendations for change evolved from the focus group. Inadequate finances to house and care for the children was the primary cause for distress in these families. The major governmental policy that hindered the social workers' ability to assist families pertained to the low financial entitlement for caregivers who are related to the orphaned child. It was noted that unrelated caregivers receive substantially more money for the care of these children than family caregivers receive. Recommendations were made to change this policy and to develop guardianship laws that facilitate families' abilities to provide care to AIDS orphans. Family caregivers of AIDS orphans are bombarded with great demands and limited resources. This analysis of their situation from the social workers' perspective is a positive step toward the improvement of support services for these families. Further research should include individual qualitative interviews assessing the needs of the caregivers and AIDS orphans.

The productivity of countries around the globe is adversely affected by the health-related problems of their labour force. This study examined the effect of the prevalence of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and life expectancy on the economic growth of 33 Sub-Saharan African (SSA) countries over a period of 11 years (2002-2012). The study employed a dynamic panel approach as opposed to the static traditional approach utilised in the literature. The dynamic approach became eminent because of the fact that HIV/AIDS is a dynamic variable as its prevalence today depends on the previous years. The result revealed that HIV/AIDS is negatively correlated with economic growth in the region, with a coefficient of 0.014, and significant at the 1% level. That is, a 10% increase in HIV/AIDS prevalence leads to a 0.14% decrease in the GDP of the region. Tackling HIV/AIDS is therefore imperative to the developing Sub-Saharan African region and all hands must be on deck to end the menace globally.

Full Text Available Abstract Background A legacy of colonial rule coupled with a devastating 16-year civil war through 1992 left Mozambique economically impoverished just as the human immunodeficiency virus (HIV epidemic swept over southern Africa in the late 1980s. The crumbling Mozambican health care system was wholly inadequate to support the need for new chronic disease services for people with the acquired immunodeficiency syndrome (AIDS. Methods To review the unique challenges faced by Mozambique as they have attempted to stem the HIV epidemic, we undertook a systematic literature review through multiple search engines (PubMed, Google Scholar™, SSRN, AnthropologyPlus, AnthroSource using Mozambique as a required keyword. We searched for any articles that included the required keyword as well as the terms 'HIV' and/or 'AIDS', 'prevalence', 'behaviors', 'knowledge', 'attitudes', 'perceptions', 'prevention', 'gender', drugs, alcohol, and/or 'health care infrastructure'. Results UNAIDS 2008 prevalence estimates ranked Mozambique as the 8th most HIV-afflicted nation globally. In 2007, measured HIV prevalence in 36 antenatal clinic sites ranged from 3% to 35%; the national estimate of was 16%. Evidence suggests that the Mozambican HIV epidemic is characterized by a preponderance of heterosexual infections, among the world's most severe health worker shortages, relatively poor knowledge of HIV/AIDS in the general population, and lagging access to HIV preventive and therapeutic services compared to counterpart nations in southern Africa. Poor education systems, high levels of poverty and gender inequality further exacerbate HIV incidence. Conclusions Recommendations to reduce HIV incidence and AIDS mortality rates in Mozambique include: health system strengthening, rural outreach to increase testing and linkage to care, education about risk reduction and drug adherence, and partnerships with traditional healers and midwives to effect a lessening of stigma.

Aid and good governance: Examining aggregate unintended effects of aid.

Dijkstra, Geske

2018-06-01

Although donors generally aim to improve governance in recipient countries by various means, critics claim that the aggregate effect of large aid flows is the deterioration of governance. Aid is said to weaken domestic accountability, sustain authoritarian regimes, increase political instability, weaken government capacities, and increase corruption. Conducting a systematic search in Web of Science, this paper reviews the empirical evidence for these unintended aggregate effects of aid on the political, administrative, and judicial dimensions of good governance. It finds that the negative effects of aid on governance are much exaggerated. The aggregate effect of aid on democracy has become more positive after the Cold War, and the effect of aid on government capacity and on reducing corruption has also improved over time. Furthermore, most studies show a positive effect of aid on political stability. These findings imply that donor intentions matter: donors that are serious about their intended effects on governance are able to mitigate the possible negative unintended effects of their aid.

Full Text Available Abstract Background Although pig-tailed macaques (Macaca nemestrina have been used in AIDS research for years, less is known about the early immunopathogenic events in this species, as compared to rhesus macaques (Macaca mulatta. Similarly, the events in early infection are well-characterized for simian immunodeficiency viruses (SIV, but less so for chimeric simian-human immunodeficiency viruses (SHIV, although the latter have been widely used in HIV vaccine studies. Here, we report the consequences of intrarectal infection with a CCR5-tropic clade C SHIV-1157ipd3N4 in pig-tailed macaques. Results Plasma and cell-associated virus was detectable in peripheral blood and intestinal tissues of all four pig-tailed macaques following intrarectal inoculation with SHIV-1157ipd3N4. We also observed a rapid and irreversible loss of CD4+ T cells at multiple mucosal sites, resulting in a marked decrease of CD4:CD8 T cell ratios 0.5–4 weeks after inoculation. This depletion targeted subsets of CD4+ T cells expressing the CCR5 coreceptor and having a CD28-CD95+ effector memory phenotype, consistent with the R5-tropism of SHIV-1157ipd3N4. All three animals that were studied beyond the acute phase seroconverted as early as week 4, with two developing cross-clade neutralizing antibody responses by week 24. These two animals also demonstrated persistent plasma viremia for >48 weeks. One of these animals developed AIDS, as shown by peripheral blood CD4+ T-cell depletion starting at 20 weeks post inoculation. Conclusion These findings indicate that SHIV-1157ipd3N4-induced pathogenesis in pig-tailed macaques followed a similar course as SIV-infected rhesus macaques. Thus, R5 SHIV-C-infection of pig-tailed macaques could provide a useful and relevant model for AIDS vaccine and pathogenesis research.

Additional recommendations to reduce sexual and drug abuse-related transmission of human T-lymphotropic virus type III/lymphadenopathy-associated virus.

Science.gov (United States)

1986-03-14

Previous US Public Health Service recommendations pertaining to sexual, IV drug abuse, and perinatal transmission of human-T-lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV) have been published. Reduction of sexual and IV transmission of HTLV-III/LAV should be enhanced by using available serologic tests to give asymptomatic, infected individuals in high-risk groups the opportunity to know their status so they can take appropriate steps to prevent the further transmission of this virus. Since the objective of these additional recommendations is to help interrupt transmission by encouraging testing and counseling among persons in high-risk groups, careful attention must be paid to maintaining confidentiality and to protecting records from any unauthorized disclosure. The ability of health departments to assure confidentiality, and the public confidence in that ability, are crucial to efforts to increase the number of persons requesting such testing and counseling. Persons at increased risk of HTLV-III/LAV infection include: homosexual and bisexual men; present or past IV drug abusers; persons with clinical or laboratory evidence of infection, such as those with signs or symptoms compatible with acquired immune deficiency syndrome (AIDS) or AIDS-related complex (ARC); persons born in countries where heterosexual transmission is thought to play a major role; male or female prostitutes and their sex partners; sex partners of infected persons or persons at increased risk; all persons with hemophilia who have received clotting-factor products; and newborn infants of high-risk or infected mothers. Recommendations include: community health education programs should be aimed at members of high-risk groups to increase knowledge of AIDS, to facilitate behavioral changes to reduce risks of HTLV-III/LAV infection, and encourage voluntary testing and counseling; counseling and voluntary serologic testing for HTLV-III/LAV should be routinely offered to

Development of vaccines capable of eliciting broadly neutralizing antibodies (bNAbs) is a key goal to controlling the global AIDS epidemic. To be effective, bNAbs must block the capture of HIV-1 to prevent viral acquisition and establishment of reservoirs. However, the role of bNAbs, particularly during initial exposure of primary viruses to host cells, has not been fully examined. Using a sensitive, quantitative, and high-throughput qRT-PCR assay, we found that primary viruses were captured by host cells and converted into a trypsin-resistant form in less than five minutes. We discovered, unexpectedly, that bNAbs did not block primary virus capture, although they inhibited the capture of pseudoviruses/IMCs and production of progeny viruses at 48h. Further, viruses escaped bNAb inhibition unless the bNAbs were present in the initial minutes of exposure of virus to host cells. These findings will have important implications for HIV-1 vaccine design and determination of vaccine efficacy. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

2013-01-01

The human immunodeficiency virus type-1 (HIV-1) is the etiological agent of the acquired immunodeficiency syndrome (AIDS), a disease highly lethal in the absence of combination antiretroviral therapy. HIV infects CD4+ cells of the immune system (T cells, monocyte-macrophages and dendritic cells) via interaction with a universal primary receptor, the CD4 molecule, followed by a mandatory interaction with a second receptor (co-receptor) belonging to the chemokine receptor family. Apart from som...

Securitizing HIV/AIDS: a game changer in state-societal relations in China?

Science.gov (United States)

Lo, Catherine Yuk-Ping

2018-05-16

China has experienced unprecedented economic growth since the 1980s. Despite this impressive economic development, this growth exists side by side with the human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and severe acute respiratory syndrome (SARS) crises and the persisting deficiencies in public health provision in China. Acknowledging the prevailing health problems, the Chinese government has encouraged the development of health non-governmental organizations (NGOs) to respond to the health challenges and address the gaps in public health provision of the government. HIV/AIDS-focused NGOs have been perceived as the most outstanding civil society group developed in China. Considering the low priority of health policies since the economic reform, the limitation of the "third sector" activity permitted in authoritarian China, together with the political sensitivity of the HIV/AIDS problem in the country, this article aims to explain the proliferation of HIV/AIDS-focused NGOs in China with the usage of the securitization framework in the field of international relations (IR). The research that underpins this article is based on a desk-based literature review as well as in-depth field interviews with individuals working in HIV/AIDS-focused NGOs in China. Face-to-face interviews for this research were conducted between January and May in 2011, and between December 2016 and January 2017, in China. Discourse analysis was in particular employed in the study of the security-threat framing process (securitization) of HIV/AIDS in China. This article argues that the proliferation of HIV/AIDS-related NGOs in China is largely attributed to the normative and technical effects of HIV/AIDS securitization ushered in by the United Nations Security Council (UNSC) and supported by the Global Fund to Fight AIDS, Tuberculosis, and Malaria (hereinafter Global Fund) observed in China. Despite depicting a positive scenario, the development of HIV/AIDS

Correlation of mental illness and HIV/AIDS infection

Full Text Available HIV/AIDS is among the leading causes of morbidity and mortality in world. There are more than 35 million people living with HIV/AIDS in the world. Although the annual incidence of HIV infection is decreasing globally, HIV prevalence is rising due to development of more effective treatment and higher survival. Iran suffers from concentrated HIV epidemics among injecting and non-injecting drug users. There are more than 27 thousand registered cases of HIV infection and it is estimated that there are above seventy eight thousand cases in the country. Regarding the burden of disease, it is projected that HIV/AIDS will have the highest growth during the next 10 years. The outcome of this epidemics will be determined by human behavior. HIV, psychiatric disorders and substance use disorders are closely correlated and are accompanied by similar risk factors. They also share common consequences such as stigma and discrimination. Correlation of psychiatric disorders, as one of the most influential determinants of our behavior, and HIV/AIDS infection is reviewed in this narrative article. Psychiatric disorders are associated with greater risk of HIV acquisition. Substance use disorders, both injecting and non-injecting, as well as severe mental illnesses put the individual at higher risk of acquiring HIV infection. Impaired judgment, diminished inhibition and control over behaviors, lack of insight and poor self-care have been proposed as the underlying mechanisms. On the other hand, HIV infection may put the individual at greater risk of developing a mental illness. Coping with a chronic and life-threatening illness, fear of stigma and discrimination, CNS invasion of the virus as well as the adverse neuropsychiatric side effects of anti-retroviral medications may all contribute to establishment of a psychiatric disorder. Although there exists a bi-directional correlation between mental health problems and HIV/AIDS infection, this reciprocity goes beyond

The highest prevalence of HIV infection occurs in Sub-Saharan Africa and hepatitis B virus (HBV), and hepatitis C virus (HCV) prevalence are the second highest in Sub-Saharan Africa including Malawi. Health-care workers (HCWs) play an important role in the prevention of, response to, and management of these infectious diseases. There is, however, no published research about the level of knowledge and attitudes toward HIV, HBV, and HCV infection among Malawian HCWs. The purpose of this study was to explore and determine the knowledge of and attitudes toward HIV, HBV, and HCV among a targeted population of Malawian HCWs. A cross-sectional community-based participatory research with 194 HCWs was completed employing health survey method. The project was a collaborative effort between nursing faculties in the USA and Malawian. A one-way analysis of variance (ANOVA) with the Bonferroni adjustment for multiple comparisons was used to assess the differences in knowledge and attitude among three subgroups of HCWs. Of 194 of Malawian HCWs surveyed, 41% were support staff, 37% were nursing students, and 22% were health-care professionals. Both health-care professionals and support staff had high knowledge scores related to HIV/AIDS, and their attitudes were mainly positive. However, a series of one-way ANOVAs revealed significant differences in knowledge and attitude toward HIV/AIDs, HBV, and HCV among HCWs ( P attitudes toward hepatitis. This study highlights the ongoing need for reducing negative attitudes toward HIV, HBV, and HCV; and providing health education among HCWs, especially focusing on HBV and HCV prevention. The findings of the research project can be used to develop interventions addressing low HBV- and HCV-related knowledge and attitudes.

To determine safety and efficacy of tumor necrosis factor (TNF) and interferon-gamma (IFN gamma) in the treatment of patients with acquired immunodeficiency syndrome (AIDS)-related complex, a randomized, double-blind study was conducted. Twenty-five patients with AIDS-related complex and CD4 lymphocytes less than or equal to 500 x 10(6)/L attended an AIDS Clinical Trials Unit of a tertiary referral center. Patients were administered tumor necrosis factor (TNF) (10 micrograms/m2) or IFN gamma (10 micrograms/m2), or both intramuscularly three times weekly for 16 weeks. Side effects from all three preparations included fever, constitutional symptoms, and local reactions. No significant hematologic, hepatic, renal, or coagulation abnormalities were observed. CD4 lymphocyte counts, beta 2-microglobulin, p24 antigen levels, and anti-p24 antibody did not change significantly during therapy. Similarly, no significant change was noted in rates of HIV isolation from peripheral blood mononuclear cells or plasma. TNF and IFN gamma were tolerable after premedication with acetaminophen; however, no significant change in markers of human immunodeficiency virus infection was demonstrated. These cytokines alone do not appear to be of benefit, nor do they appear to hasten the progression of HIV infection.

Despite advances made in recent years in medical first aid, psychiatric intervention, survival training and equipment design, many people still perish quickly during and immediately following a disastrous event. In this study, individuals and groups of survivors of life-threatening events were debriefed and the behavior of those who coped well during such a threat to life were compared with those who did not. The behaviors of those who coped well were distilled into a set of principles for psychological first aid; that is, a series of simple actions for use within a disaster which serves to recover victims to functional behavior as quickly as possible, thus increasing their chance for survival. These principles of psychological first aid have recently been introduced into basic first aid and survival training courses for both military and civilian units.

Full Text Available Orientation: In light of the human immunodeficiency virus (HIV pandemic, and in order to improve competitiveness in the South African private sector, many structures have implemented subsidised workplace programmes. Research purpose: The aim of this study was to collect baseline data regarding the knowledge, attitudes, practices and belief (KAPB of employees in the automotive industry in relation to HIV and AIDS, in order to assess the need for HIV and AIDS workplace programmes. Motivation for the study: Given the abundance of HIV and AIDS information, the question is whether these workplace programmes’ efforts are still relevant. Research design, approach and method: A quantitative descriptive study design was used using a self-administered questionnaire covering questions about KAPB with regard to HIV and AIDS. The data collection took place in seven automotive supplier companies in South Africa (n = 733 who were going to implement HIV and AIDS workplace programmes with the support of the Automotive Industry Development Centre in the Eastern Cape. Main findings: High-risk behaviour, as indicated by sexual relations with more than one partner in the last 12 months, occurred in between 12% (management and 42% (cleaners of employees. All risk behaviour indicators showed significant differences (p < 0.05 between management and administrative staff on the one hand and technicians, operators and cleaners on the other. Despite being aware of an HIV policy, more than 50% of employees indicated that they would not be willing to disclose their status. Practical/managerial implications: As HIV and AIDS risk behaviour and stigma remain a problem, HIV infection with associated health problems may threaten productivity in the automotive industry if no measures are taken to address the impact on employees and the company. Contribution: This study strongly supports the conclusion that KAPB studies can still provide important information to tailor HIV

Ranaviral disease has affected several species of reptiles, but disease progression and mortality in relation to environmental temperature has yet to be determined. In this study, two separate trials challenged adult female red-eared slider turtles (Trachemys scripta elegans) with a ranavirus (frog virus 3-like virus; FV3) isolate at environmental temperatures of 22 °C (n = 4) and 28 °C (n = 4). The mortality rates in the turtles in the 22 °C and 28 °C trials were 100% and 50%, respectively. Median survival time for turtles exposed to FV3 at 22 °C was 24 days, while it was 30 days in the group kept at 28 °C. Consistent microscopical lesions were observed only in the group inoculated at 22 °C and included fibrinoid necrosis of vessels in the spleen, vascular and sinusoidal thrombi in the liver, necrotizing myositis and a mild heterophilic interstitial pneumonia. Quantitative polymerase chain reaction, targeting a conserved portion of the major capsid protein, was able to detect virus copies in whole blood, oral and cloacal swabs, tongue, skeletal muscle, lung, heart, liver, spleen, ovary and kidney. Viral copy number in ante-mortem clinical samples was non-significantly highest in whole blood, while kidney had the highest viral copy number in post-mortem samples. All samples had higher virus copy number in turtles exposed to FV3 at 22 °C compared with 28 °C. This study determined that environmental temperature affects the survival and disease progression in ranavirus-infected red-eared slider turtles, which will aid in managing animals in a clinical or free-ranging setting.

To examine the occurrence, hydrologic variability, and seasonal variability of human and bovine viruses in surface water, three stream locations were monitored in the Milwaukee River watershed in Wisconsin, USA, from February 2007 through June 2008. Monitoring sites included an urban subwatershed, a rural subwatershed, and the Milwaukee River at the mouth. To collect samples that characterize variability throughout changing hydrologic periods, a process control system was developed for unattended, large-volume (56–2800 L) filtration over extended durations. This system provided flow-weighted mean concentrations during runoff and extended (24-h) low-flow periods. Human viruses and bovine viruses were detected by real-time qPCR in 49% and 41% of samples (n = 63), respectively. All human viruses analyzed were detected at least once including adenovirus (40% of samples), GI norovirus (10%), enterovirus (8%), rotavirus (6%), GII norovirus (1.6%) and hepatitis A virus (1.6%). Three of seven bovine viruses analyzed were detected including bovine polyomavirus (32%), bovine rotavirus (19%), and bovine viral diarrhea virus type 1 (5%). Human viruses were present in 63% of runoff samples resulting from precipitation and snowmelt, and 20% of low-flow samples. Maximum human virus concentrations exceeded 300 genomic copies/L. Bovine viruses were present in 46% of runoff samples resulting from precipitation and snowmelt and 14% of low-flow samples. The maximum bovine virus concentration was 11 genomic copies/L. Statistical modeling indicated that stream flow, precipitation, and season explained the variability of human viruses in the watershed, and hydrologic condition (runoff event or low-flow) and season explained the variability of the sum of human and bovine viruses; however, no model was identified that could explain the variability of bovine viruses alone. Understanding the factors that affect virus fate and transport in rivers will aid watershed management for minimizing

Full Text Available Background: Young people are most vulnerable to sexually transmitted diseases (STDs and human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS in Bangladesh. Lack of knowledge about reproductive health issues is also common in this group. Aims: This study aimed to assess the knowledge and perceptions of STDs, HIV/AIDS, and reproductive health of young female university students (19-27 years in Dhaka, Bangladesh. Methods: A cross-sectional study was carried out among 402 female students from seven universities in Dhaka, Bangladesh. Data were collected through face-to-face interviews using a structured questionnaire on sociodemographic information, knowledge, and perceptions of STDs, HIV/AIDS, and reproductive health. Descriptive analysis was used, and data were presented as frequencies and percentages. Results: The majority of the participants were young, unmarried, undergraduate students. Most of the participants reported that they knew about STDs (79% and HIV/AIDS (66%. However, knowledge about the modes of transmission and prevention of the diseases was poor. HIV/AIDS was considered by 90% participants as a public health threat to Bangladesh, mostly due to illiteracy (76%, increased mortality (20%, existence of risky sexual behavior (18%, and aggression of Western culture (31%. About 65% of the participants mentioned that AIDS can be prevented by safe sexual practice, 55% mentioned prevention through upholding religious values and moral education, and 59% mentioned that education about AIDS would help prevent transmission. Conclusions: Although a majority of young Bangladeshi female students reported knowing about HIV/AIDS, their knowledge regarding transmission and prevention of the diseases was poor. Strategies for creating reproductive health education targeted at young female students are essential for the prevention of STDs and HIV/AIDS.

Full Text Available There are number of Non-Governmental Organisations (NGOs in South Africa that use sport as a tool to respond to Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS, however, little is reported about the outcomes and impact of these programmes. The aim of this study is to contribute to a generic monitoring and evaluation framework by improving the options for the use of outcome indicators of sport-based HIV/AIDS awareness programmes of selected NGOs in South Africa. A qualitative method study was carried out with seven employees of five selected NGOs that integrate sport to deliver HIV/AIDS programmes in South Africa. The study further involved six specialists/experts involved in the field of HIV/AIDS and an official from Sport Recreation South Africa (SRSA. Multiple data collection instruments including desktop review, narrative systematic review, document analysis, one-on-one interviews and focus group interview were used to collect information on outcomes and indicators for sport-based HIV/AIDS awareness programmes. The information was classified according to the determinants of HIV/AIDS. The overall findings revealed that the sport-based HIV/AIDS awareness programmes of five selected NGOs examined in this study focus on similar HIV prevention messages within the key priorities highlighted in the current National Strategic Plan for HIV/AIDS, STIs and TB of South Africa. However, monitoring and evaluating outcomes of sport-based HIV/AIDS programmes of the selected NGOs remains a challenge. A need exists for the improvement of the outcome statements and indicators for their sport-based HIV/AIDS awareness programmes. This study proposed a total of 51 generic outcome indicators focusing on measuring change in the knowledge of HIV/AIDS and change in attitude and intention towards HIV risk behaviours. In addition, this study further proposed a total of eight generic outcome indicators to measure predictors of HIV risk behaviour

Full Text Available In many communities of South Africa, traditional healers are often the only means of health care delivery available. The level of knowledge and ability to recognize oral lesions of 32 traditional healers and 17 care-givers were assessed after a two-day workshop. The data collection instrument was a structured questionnaire, complimented by enlarged clinical photographs of the common oral manifestations of HIV/AIDS. Prior to the workshop, 46 (93.9% of the 49 respondents had never had any formal information on oral health and 43 (87.8% were unfamiliar with the symptoms of oral diseases. Thirty-five (71.4% recognized bleeding gums from A4-size photographs and 11 (22.4% recognized oral thrush. The recognition of other oral manifestations of HIV/AIDS were; oral hairy leukoplakia (41.0%, angular cheilitis (43.6%, herpes virus infection (56.4%, oral ulcerations (56.8%, and in children, parotid enlargement (27.3%, and moluscum contagiosum (56.8%. Traditional healers and caregivers constitute an untapped resource with enormous potential. A positive bridge should be built to link traditional healing with modem medicine in the struggle against HIV/AIDS.

Full Text Available Objectives: Infections caused by human immunodeficiency virus (HIV, hepatitis B virus (HBV and hepatitis C virus (HCV represent a significant health problem. Co-infection with these viral agents is not uncommon as a result of the similar transmission routes. Our study was planned to investigate the prevalence of HBV and HCV infections in HIV/Acquired Immune Deficiency syndrome (AIDS patients followed up at our institution. Materials and Methods: In this study conducted in the Department of Infectious Diseases and Clinical Microbiology at Izmir Tepecik Training and Research Hospital, medical records of patients followed at the HIV/AIDS outpatient clinic between August 2002 and December 2014 were evaluated. Demographic data, main route of HIV transmission, hepatitis B surface antigen (HBsAg, anti-hepatitis B core (HBc immunoglobulin G (IgG, anti-HBs and anti-HCV results were evaluated. Results: A total of 157 treatment-naïve patients who were followed up at our HIV/AIDS outpatient clinic were included in this study. Four patients (2.6%, had HBsAg positivity. Anti-HBc IgG and anti-HBs positivity were detected in 34% and 28.4% of the patients, respectively. No patients had anti-HCV positivity. Conclusion: The prevalence of HBsAg in HIV-positive individuals was found to be similar to that in other population-based studies in our country. Absence of anti-HCV positivity suggests that hepatitis C infection is not a major health problem in this population.

The brain may be affected by a variety of abnormalities in association with human immunodeficiency virus (HIV) infection. Knowledge of their existence and characteristic imaging features are important to radiologists for detection, diagnosis, and initiation of an appropriate treatment. Although there is a considerable overlap in the imaging characteristics of different entities, some findings are found to be very suggestive of a particular disease. The CT and MR imaging techniques are commonly used in the diagnosis of neurological disorders in acquired immunodeficiency syndrome (AIDS) patients, to verify treatment response and to guide brain biopsy. This review attempts to describe CT and MR features of infectious and malignant brain disorders in HIV-seropositive patients. (orig.). With 13 figs

Background. The compilation of previous genomewide association studies of AIDS shows a major polymorphism in the HCP5 gene associated with both control of the viral load and long-term nonprogression (LTNP) to AIDS. Methods. To look for genetic variants that affect LTNP without necessary control of the viral load, we reanalyzed the genomewide data of the unique LTNP Genomics of Resistance to Immunodeficiency Virus (GRIV) cohort by excluding “elite controller” patients, who were controlling the viral load at very low levels (<100 copies/mL). Results. The rs2234358 polymorphism in the CXCR6 gene was the strongest signal (P = 2.5 × 10−7; odds ratio, 1.85) obtained for the genomewide association study comparing the 186 GRIV LTNPs who were not elite controllers with 697 uninfected control subjects. This association was replicated in 3 additional independent European studies, reaching genomewide significance of Pcombined = 9.7 × 10−10. This association with LTNP is independent of the combined CCR2-CCR5 locus and the HCP5 polymorphisms. Conclusion. The statistical significance, the replication, and the magnitude of the association demonstrate that CXCR6 is likely involved in the molecular etiology of AIDS and, in particular, in LTNP, emphasizing the power of extreme-phenotype cohorts. CXCR6 is a chemokine receptor that is known as a minor coreceptor in human immunodeficiency virus type 1 infection but could participate in disease progression through its role as a mediator of inflammation.

This article describes the development and implementation of an acquired immune deficiency syndrome (AIDS) intervention program for female sex partners of male injection-drug users. Four psychoeducational workshops were designed to motivate personal risk reduction, provide participants with necessary cognitive and behavioral skills, and enhance participants' perceived ability to enact positive changes in their lives. The development of the workshop modules was guided by traditional theories of health behavior change and social learning. Also included in the intervention are referral and advocacy services, personal risk reduction counseling, and human immunodeficiency virus (HIV) antibody testing. Preliminary results indicate that the program has made a significant impact on the AIDS risk of participants--91 percent of women who completed the program reported that they had made positive changes in their lives to reduce their risk of HIV infection.

The association of Merkel cell polyomavirus (MCP y V) with Merkel cell carcinoma (MCC) in immunocompromised individuals has been revealed in a number of surveys. The study of MCP y V specific antibody titers and viral loads in such patients has a great attraction for research groups interested in viral reactivation. In this cross-sectional study to evaluate MCP y V antibody titer, DNA prevalence and viral load in peripheral blood mononuclear cells (PBMCs), we examined 205 HIV-1 infected patients and 100 un-infected controls. The HIV-1 infected patients divided into two groups (HIV/AIDS and non-AIDS) according to their CD4 status. Total IgG antibody titer against MCP y V was analyzed by virus like particle (VLP)-based enzyme linked immunosorbent assay (ELISA). Presence of MCP y V-DNA in subject's PBMCs was examined by quantitative real-time PCR assay. Levels of anti-MCP y V IgG in HIV/AIDS patients were significantly higher than those in non-AIDS HIV-infected and control subjects (p value = <0.001). The prevalence rate of MCP y V-DNA in PBMCs of HIV/AIDS, non-AIDS HIV-infected and un-infected controls were 17%, 16%, and 14% respectively. The MCP y V viral load among the groups ranged between 0.15 to 2.9 copies/10 3 cells (median, 1.9 copies/10 3 cells), with no significant difference between the studied populations (p value = 0.3).

Illinois court seeks new course in AIDS phobia cases.

Science.gov (United States)

1997-07-25

The Illinois Court of Appeals ruled that plaintiffs cannot be compensated for negligent infliction of emotional distress unless there is a substantial, medically-verifiable possibility of contracting HIV. The new standard will impact a growing body of case law requiring plaintiffs to show that the fear of AIDS was predicated on actual exposure to the virus. Under the actual exposure rule, a plaintiff who injures himself with a hypodermic needle that had been used on an HIV-positive hospital patient could recover damages; another plaintiff whose needle puncture cannot be traced to HIV contamination could not be compensated. In Doe v. Northwestern University, six plaintiffs who received dental care from a university dental student who tested positive for HIV antibodies sued the university, alleging negligence. Although the plaintiff's fears of HIV infection were reasonable, the court found that they were not severe enough to warrant tort compensation since the plaintiffs had nothing to support their claims. In the case of [name removed] v. [Name removed], a medical clinic office manager, cut herself on a bloodstained scalpel left in a trash can by Dr. [name removed]. Eight months following the incident, [name removed] died of AIDS-related causes. Mrs. [Name removed] would have been entitled to recover damages under the actual exposure test; however, the case would not have prevailed under the Northwestern standard because it was known that Mrs. [Name removed] tested negative twice prior to learning of [name removed]'s AIDS diagnosis. Controversy within the Illinois courts about the actual exposure rule continues.

Full Text Available Persons infected with the Human Immunodeficiency Virus (HIV are particularly susceptible to tuberculosis, either by latent infection reactivation or by a primary infection with rapid progression to active disease. This study was done to determine the frequency of tuberculosis infection among Iranian patients with HIV/AIDS. A total of 262 HIV/AIDS patients attending all three HIV/AIDS health care centers of Tehran, Iran were enrolled in this study. A detailed history and physical examination were obtained from all HIV patients suspected of having pulmonary M. tuberculosis. A positive PPD skin test was used as a diagnostic parameter for probability of TB infection. Out of 262 HIV/AIDS patients, a total of 63 (24% were shown to have the tuberculosis infection based on a positive PPD skin test. Of the patients with positive PPD skin test, 22 (35% had pulmonary Tuberculosis, 2 (3.2% had extrapulmonary tuberculosis, and 39 (53% had no evidence of M. tuberculosis infection (latent infection. Also 8 (12.7% had history of long term residence in a foreign country, 32 (50.8% were exposed to an index case, and 9 (14.3% had past history of pulmonary tuberculosis, while only 33.3% had clinical manifestations of TB (active disease. There was no resistant case of tuberculosis. Our study showed that near 24% of Iranian patients with HIV/AIDS were infected with M. tuberculosis. This finding denotes the need to improve the diagnostic and preventive measures, and also prompt treatment of this type of infection in the HIV infected individuals.

The Master Hearing Aid

Science.gov (United States)

Curran, James R.

2013-01-01

As early as the 1930s the term Master Hearing Aid (MHA) described a device used in the fitting of hearing aids. In their original form, the MHA was a desktop system that allowed for simulated or actual adjustment of hearing aid components that resulted in a changed hearing aid response. Over the years the MHA saw many embodiments and contributed to a number of rationales for the fitting of hearing aids. During these same years, the MHA was viewed by many as an inappropriate means of demonstrating hearing aids; the audio quality of the desktop systems was often superior to the hearing aids themselves. These opinions and the evolution of the MHA have molded the modern perception of hearing aids and the techniques used in the fitting of hearing aids. This article reports on a history of the MHA and its influence on the fitting of hearing aids. PMID:23686682

A multidisciplinary team of 20 researchers and research users from six countries - Canada, Jamaica, Barbados, Kenya, Uganda and South Africa - are collaborating on a 5-year (2007-12) program of research and capacity building project. This program of research situates nurses as leaders in building capacity and promotes collaborative action with other health professionals and decision-makers to improve health systems for human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) nursing care. One of the projects within this program of research focused on the influence of workplace policies on nursing care for individuals and families living with HIV. Nurses are at the forefront of HIV prevention and AIDS care in these countries but have limited involvement in related policy decisions and development. In this paper, we present findings related to the barriers and facilitators for nurses' engagement in policymaking. A participatory action research design guided the program of research. Purposive sampling was used to recruit 51 nurses (unit managers, clinic and healthcare managers, and senior nurse officers) for interviews. Participants expressed the urgent need to develop policies related to AIDS care. The need to raise awareness and to 'protect' not only the workers but also the patients were critical reason to develop policies. Nurses in all of the participating countries commented on their lack of involvement in policy development. Lack of communication from the top down and lack of information sharing were mentioned as barriers to participation in policy development. Resources were often not available to implement the policy requirement. Strong support from the management team is necessary to facilitate nurses involvement in policy development. The findings of this study clearly express the need for nurses and all other stakeholders to mobilize nurses' involvement in policy development. Long-term and sustained actions are needed to address

2011-01-01

The Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) pandemic has caused far-reaching effects in sub-Saharan Africa. The pandemic has effectively diminished the workforce, increased poverty rates, reduced agricultural productivity, and transformed the structure of many rural households. HIV/AIDS further strains the already fragile relationship between livelihood and the natural and social environments of these regions. Therefore, the objective of this review is to characterize the impact of HIV/AIDS on the environment and the social infrastructure of rural sub-Saharan Africa. There are many aspects of rural life that contribute to disease transmission of HIV/AIDS and that pose unique challenges to the population dynamics in sub-Saharan Africa. Widespread AIDS-related mortality has caused a decrease in population growth for many African countries. In turn, these alterations in population dynamics have resulted in a decrease in the percentage of prime-age working adults, as well as a gender disparity, whereby, females carry a growing burden of household responsibilities. There is a rising proportion of older adults, often females, who assume the role of provider and caretaker for other dependent family members. These changing dynamics have caused many to exploit their natural surroundings, adopting less sustainable land use practices and utilizing protected resources as a primary means of generating revenue.

Kolgiri, Vaishali; Patil, Vinayak Wamanrao

The major complications of "treated" Human Immunodeficiency Virus (HIV) infection are cardiovascular disease, malignancy, renal disease, liver disease, bone disease, and perhaps neurological complications, which are phenomena of the normal aging process occurring at an earlier age in the HIV-infected population. The present study is aimed to explore protein carbonyl content as a biomarker for detecting oxidative DNA damage induced ART toxicity and/or accelerated aging in HIV/AIDS patients. To investigate the potential of carbonyl content as a biomarker for detecting oxidative Deoxyribonucleic acid (DNA) damage induced Antiretroviral Theraphy (ART) toxicity and/or accelerated aging in HIV/AIDS patients. In this case-control study a total 600 subjects were included. All subjects were randomly selected and grouped as HIV-negative (control group) (n=300), HIV-infected ART naive (n=100), HIV-infected on first line ART (n=100), and HIV-infected on second line ART (n=100). Seronegative control subjects were age- and sex-matched with the ART naive patients and the two other groups. Carbonyl protein was determined by the method described in Levine et al. DNA damage marker 8-OH-dG was determined using 8-hydroxy-2-deoxy Guanosine StressXpress ELA Kit by StressMarq Biosciences. Protein carbonyl content levels and oxidative DNA damage were significantly higher (paging in HIV/AIDS patients. Larger studies are warranted to elucidate the role of carbonyl content as a biomarker for premature aging in HIV/AIDS patients. Copyright © 2016 Sociedade Brasileira de Infectologia.

The emergence and evolution of the research fronts in HIV/AIDS research.

Directory of Open Access Journals (Sweden)

David Fajardo-Ortiz

Full Text Available In this paper, we have identified and analyzed the emergence, structure and dynamics of the paradigmatic research fronts that established the fundamentals of the biomedical knowledge on HIV/AIDS. A search of papers with the identifiers "HIV/AIDS", "Human Immunodeficiency Virus", "HIV-1" and "Acquired Immunodeficiency Syndrome" in the Web of Science (Thomson Reuters, was carried out. A citation network of those papers was constructed. Then, a sub-network of the papers with the highest number of inter-citations (with a minimal in-degree of 28 was selected to perform a combination of network clustering and text mining to identify the paradigmatic research fronts and analyze their dynamics. Thirteen research fronts were identified in this sub-network. The biggest and oldest front is related to the clinical knowledge on the disease in the patient. Nine of the fronts are related to the study of specific molecular structures and mechanisms and two of these fronts are related to the development of drugs. The rest of the fronts are related to the study of the disease at the cellular level. Interestingly, the emergence of these fronts occurred in successive "waves" over the time which suggest a transition in the paradigmatic focus. The emergence and evolution of the biomedical fronts in HIV/AIDS research is explained not just by the partition of the problem in elements and interactions leading to increasingly specialized communities, but also by changes in the technological context of this health problem and the dramatic changes in the epidemiological reality of HIV/AIDS that occurred between 1993 and 1995.

As a first step in designing an AIDS prevention program at a large factory in Kinshasa, Zaire, we collected information on attitudes towards human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) from factory foremen and their wives. Trained moderators conducted twelve focus group discussions (from November through December 1987) that addressed knowledge, attitudes and beliefs about HIV infection and AIDS. In general, participants were familiar with HIV infection and AIDS and considered these conditions leading health problems in Kinshasa. Although participants had a fairly accurate understanding of the causes of HIV infection, modes of transmission and preventive measures, many myths and misconceptions existed. Many participants did not believe that condom use would consistently prevent infection through sexual intercourse. Participants strongly favored the counseling of seropositive persons but showed less consensus about whether the spouse of a seropositive person should be notified of the partner's test result. Participants predicted that couples in which one member is seropositive and the other is not would experience marital discord and friction with family, neighbors and co-workers. These findings were applied to the development of a counseling and educational program for seropositive factory employees and their spouses.

A critical assessment of theories/models used in health communication for HIV/AIDS.

Science.gov (United States)

Airhihenbuwa, C O; Obregon, R

2000-01-01

Most theories and models used to develop human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) communication are based on social psychology that emphasizes individualism. Researchers including communication and health scholars are now questioning the presumed global relevance of these models and thus the need to develop innovative theories and models that take into account regional contexts. In this paper, we discuss the commonly used theories and models in HIV/AIDS communication. Furthermore, we argue that the flaws in the application of the commonly used "classical" models in health communication are because of contextual differences in locations where these models are applied. That is to say that these theories and models are being applied in contexts for which they were not designed. For example, the differences in health behaviors are often the function of culture. Therefore, culture should be viewed for its strength and not always as a barrier. The metaphorical coupling of "culture" and "barrier" needs to be exposed, deconstructed, and reconstructed so that new, positive, cultural linkages can be forged. The HIV/AIDS pandemic has served as a flashpoint to either highlight the importance or deny the relevance of theories and models while at the same time addressing the importance of culture in the development and implementation of communication programs.

Women are disproportionally affected by human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) in sub-Saharan Africa (SSA). The determinants of gender inequality in HIV/AIDS may vary across countries and require country-specific interventions to address them. This study aimed to identify the socio-demographic and behavioral characteristics underlying gender inequalities in HIV/AIDS in 21 SSA countries. We applied an extension of the Blinder-Oaxaca decomposition approach to data from Demographic and Health Surveys and AIDS Indicator Surveys to quantify the differences in HIV/AIDS prevalence between women and men attributable to socio-demographic factors, sexual behaviours, and awareness of HIV/AIDS. We decomposed gender inequalities into two components: the percentage attributable to different levels of the risk factors between women and men (the "composition effect") and the percentage attributable to risk factors having differential effects on HIV/AIDS prevalence in women and men (the "response effect"). Descriptive analyses showed that the difference between women and men in HIV/AIDS prevalence varied from a low of 0.68 % (P = 0.008) in Liberia to a high of 11.5 % (P distributions of HIV/AIDS risk factors, particularly age at first sex between women and men. In the majority of countries, however, observed gender inequalities in HIV/AIDS were chiefly explained by differences in the responses to risk factors; the differential effects of age, marital status and occupation on prevalence of HIV/AIDS for women and men were among the significant contributors to this component. In Cameroon, Guinea, Malawi and Swaziland, a combination of the composition and response effects explained gender inequalities in HIV/AIDS prevalence. The factors that explain gender inequality in HIV/AIDS in SSA vary by country, suggesting that country-specific interventions are needed. Unmeasured factors also contributed substantially to the difference in HIV/AIDS

Nairobi sheep disease virus/Ganjam virus.

Science.gov (United States)

M D, Baron; B, Holzer

2015-08-01

Nairobi sheep disease virus (NSDV) is a tick-borne virus which causes a severe disease in sheep and goats, and has been responsible for several outbreaks of disease in East Africa. The virus is also found in the Indian subcontinent, where it is known as Ganjam virus. The virus only spreads through the feeding of competent infected ticks, and is therefore limited in its geographic distribution by the distribution of those ticks, Rhipicephalus appendiculata in Africa and Haemaphysalis intermedia in India. Animals bred in endemic areas do not normally develop disease, and the impact is therefore primarily on animals being moved for trade or breeding purposes. The disease caused by NSDV has similarities to several other ruminant diseases, and laboratory diagnosis is necessary for confirmation. There are published methods for diagnosis based on polymerase chain reaction, for virus growth in cell culture and for other simple diagnostic tests, though none has been commercialised. There is no established vaccine against NSDV, although cell-culture attenuated strains have been developed which show promise and could be put into field trials if it were deemed necessary. The virus is closely related to Crimean-Congo haemorrhagic fever virus, and studies on NSDV may therefore be useful in understanding this important human pathogen.

Macaque homologs of EBV and KSHV show uniquely different associations with simian AIDS-related lymphomas.

Full Text Available Two gammaherpesviruses, Epstein-Barr virus (EBV (Lymphocryptovirus genus and Kaposi's sarcoma-associated herpesvirus (KSHV (Rhadinovirus genus have been implicated in the etiology of AIDS-associated lymphomas. Homologs of these viruses have been identified in macaques and other non-human primates. In order to assess the association of these viruses with non-human primate disease, archived lymphoma samples were screened for the presence of macaque lymphocryptovirus (LCV homologs of EBV, and macaque rhadinoviruses belonging to the RV1 lineage of KSHV homologs or the more distant RV2 lineage of Old World primate rhadinoviruses. Viral loads were determined by QPCR and infected cells were identified by immunolabeling for different viral proteins. The lymphomas segregated into three groups. The first group (n = 6 was associated with SIV/SHIV infections, contained high levels of LCV (1-25 genomes/cell and expressed the B-cell antigens CD20 or BLA.36. A strong EBNA-2 signal was detected in the nuclei of the neoplastic cells in one of the LCV-high lymphomas, indicative of a type III latency stage. None of the lymphomas in this group stained for the LCV viral capsid antigen (VCA lytic marker. The second group (n = 5 was associated with D-type simian retrovirus-2 (SRV-2 infections, contained high levels of RV2 rhadinovirus (9-790 genomes/cell and expressed the CD3 T-cell marker. The third group (n = 3 was associated with SIV/SHIV infections, contained high levels of RV2 rhadinovirus (2-260 genomes/cell and was negative for both CD20 and CD3. In both the CD3-positive and CD3/CD20-negative lymphomas, the neoplastic cells stained strongly for markers of RV2 lytic replication. None of the lymphomas had detectable levels of retroperitoneal fibromatosis herpesvirus (RFHV, the macaque RV1 homolog of KSHV. Our data suggest etiological roles for both lymphocryptoviruses and RV2 rhadinoviruses in the development of simian AIDS-associated lymphomas and indicate that

The priority dispute between Robert C. Gallo and Luc Montagnier over the discovery of the human immunodeficiency virus is briefly addressed. The final confirmation of the French priority was provided by the fact that the Nobel Prize in Medicine 2008 was awarded to Luc Montagnier and Francoise Barré--Sinoussi from the Pasteur Institute in Paris.

Radiological study of the brain at various stages of human immunodeficiency virus infection: early development of brain atrophy

International Nuclear Information System (INIS)

Raininko, R.; Elovaara, I.; Virta, A.; Valanne, L.; Haltia, M.; Valle, S.L.

1992-01-01

One hundred and one persons infected with human immunodeficiency virus (HIV-1), in whom other central nervous system infections or diseases were excluded, underwent brain CT and/or MRI at various stages of HIV-1 infection: 29 were asymptomatic (ASX), 35 had lymphadenopathy syndrome (LAS), 17 had AIDS-related complex (ARC), and 20 had AIDS. A control group of 32 HIV-1-seronegative healthy persons underwent brain MRI. The most common finding was brain atrophy. The changes were bilateral and symmetrical, and they were more severe at later stages of infection. Non-specific small hyperintense foci were found on MRI in 13% of controls and 6-15% of the infected groups. Larger, diffuse, bilateral white matter infiltrates were detected in 4 demented patients with AIDS. Four patients with AIDS and 1 with LAS had focal hyperintense lesions in the internal capsules, lentiform nuclei or thalamus, often bilateral on MRI. One patient with AIDS examined with CT only, had low density in the lentiform nucleus. Loss of brain parenchyma can occur at an early stage of HIV-1 infection, and the atrophic process becomes more intense at later stages (ARC and AIDS). (orig./GDG)

In this article, we use data from the 2013 and 2015 Australian Aid Stakeholder Surveys to gauge the extent of the changes to the Australian Government Aid Program since the 2013 federal election. The two surveys targeted the same set of stakeholders of the aid program, and both gathered data on a wide range of aspects of its functioning. As we assess the findings that emerged from the surveys, we situate our work amongst recent academic studies that have looked at the post-2013 aid changes in Australia. Our key findings are that the post-2013 changes to Australian aid have had wide-ranging impacts and have led to deteriorating overall aid quality. However, changes have not affected all aspects of the aid program equally, and some changes are starting to be reversed. In discussion, we examine what these developments mean for the future of Australian aid.

The enhanced-sensitivity Trofile assay (Monogram Biosciences) was used to retest coreceptor use at both study screening and study entry for 118 treatment-experienced subjects in AIDS Clinical Trials Group A5211 who had CCR5-tropic (R5) virus detected by the original Trofile assay at study screening. Among 90 recipients of vicriviroc, a significantly (P< .001) greater mean reduction in HIV-1 RNA was observed in 72 subjects with R5 virus versus 15 subjects reclassified as having dual/mixed-tropic viruses at screening: -1.11 versus -0.09 log(10) copies/mL at day 14 and -1.91 versus -0.57 log(10) copies/mL at week 24, respectively. Results suggest that the enhanced-sensitivity assay is a better screening tool for determining patient eligibility for CCR5 antagonist therapy.

With international funding decreasing, determining the total cost of HIV/AIDS treatment is necessary in order to develop a master plan for the transition of ART services delivery and management. We analyzed the costs of HIV/AIDS treatment paid by both HIV programs and patients in a central outpatient clinic, and we explored factors associated with the capacity of patients to pay for this service. Methods: Patients (n=315 receiving ART in the Department of Infectious Diseases at Bach Mai Hospital, Hanoi, Vietnam, were interviewed. Patient records and expenses were reviewed. Results: The total cost of ART per patient was US$611 (75% from health care providers, 25% from patients or their families. The cost of a second-line regimen was found to be 2.7 times higher than the first-line regimen cost. Most outpatients (73.3% were able to completely pay for all of their ART expenses. Capacity to pay for ART was influenced by five factors, including marital status, distance from house to clinic, patient's monthly income, household economic condition, and health insurance status. Most of the patients (84.8% would have been willing to pay for health insurance if a copayment scheme for ART were to be introduced. Conclusion: This study provides evidence on payment capacity of HIV/AIDS patients in Vietnam and supplies information on ART costs from both provider and patient perspectives. In particular, results from this study suggest that earlier access to ART

Virus titration may constitute a drawback in the development and use of replication-defective viral vectors like Semliki Forest virus (SFV). The standardization and validation of a reverse transcription quantitative PCR (qRT-PCR) method for SFV titration is presented here. The qRT-PCR target is located within the nsp1 gene of the non-structural polyprotein SFV region (SFV RNA), which allows the strategy to be used for several different recombinant SFV constructs. Titer determinations were carried out by performing virus titration and infection assays with SFVs containing an RNA coding region for the rabies virus glycoprotein (RVGP) or green fluorescent protein (GFP). Results showed that the standardized qRT-PCR is applicable for different SFV constructs, and showed good reproducibility. To evaluate the correlation between the amount of functional SFV RNA in a virus lot and its infectivity in BHK-21 cell cultures, a temperature mediated titer decrease was performed and successfully quantitated by qRT-PCR. When used for cell infection at the same multiplicity of infection (MOI), the temperature treated SFV-RVGP samples induced the same levels of RVGP expression. Similarly, when different SFV-GFP lots with different virus titers, as accessed by qRT-PCR, were used for cell infection at the same MOI, the cultures showed comparable amounts of fluorescent cells. The data demonstrate a good correlation between the amount of virus used for infection, as measured by its SFV RNA, and the protein synthesis in the cells. In conclusion, the qRT-PCR method developed here is accurate and enables the titration of replication-defective SFV vectors, an essential aid for viral vector development as well as for establishment of production bioprocesses.

Infection with the Human Immunodeficiency Virus type 1 (HIV-1) may produce a variety of central nervous system (CNS) symptoms and signs. CNS involvement in patients with the Acquired Immunodeficiency Syndrome (AIDS) includes AIDS dementia complex or HIV-1 associated cognitive/motor complex (widely known as HIV encephalopathy), progressive multifocal leucoencephalopathy (PML), opportunistic infections such as Toxoplasma gondii, TB, Cryptococcus and infiltration by non-Hodgkin's B cell lymphoma. High resolution structural imaging investigations, either X-ray Computed Tomography (CT scan) or Magnetic Resonance Imaging (MRI) have contributed to the understanding and definition of cerebral damage caused by HIV encephalopathy. Atrophy and mainly high signal scattered white matter abnormalities are commonly seen with MRI. PML produces focal white matter high signal abnormalities due to multiple foci of demyelination. However, using structural imaging techniques there are no reliable parameters to distinguish focal lesions due to opportunistic infection (Toxoplasma gondii abscess) from neoplasm (lymphoma infiltration). It is studied the use of radionuclide brain imaging techniques in the investigation of HIV infected patients. Brain perfusion Single Photon Emission Tomography (SPET), neuroreceptor and Positron Emission Tomography (PET) studies are reviewed. Greater emphasis is put on the potential of some radiopharmaceuticals, considered to be brain tumour markers, to distinguish intracerebral lymphoma infiltration from Toxoplasma infection. SPET with 201 Tl using quantification (tumour to non-tumour radioactivity ratios) appears a very promising technique to identify intracerebral lymphoma

Multiorgan involvement due to cytomegalovirus infection in AIDS

Directory of Open Access Journals (Sweden)

Shounak Majumder

Full Text Available Cytomegalovirus (CMV infection is a relatively late complication of AIDS. Like other viruses contributing to co-morbidity of HIV infection, cytomegalovirus has the propensity to cause multiorgan involvement. We report the case of a 34-year-old seropositive man who presented with bilateral lower limb weakness and symptomatic pallor. He was already on antiretroviral drugs for a month prior to presentation. Detailed clinical examination and laboratory investigations revealed cytomegalovirus polyradiculoneuropathy associated with bone marrow dysplasia. Dysplasia of haematopoeitic cell lines occurs in 30% to 70% of HIV infected patients, and is often indistinguishable from myelodysplastic syndrome. However, in our case, the bone marrow picture reverted back to normal with treatment of the CMV infection, pointing to a possible role of CMV as the causative agent of bone marrow dysplasia. Moreover, CMV has been incriminated as a pathogen producing the immune reconstitution inflammatory syndrome. The onset of the disease in our case one month after initiation of HAART strongly raises the possibility of this being a case of CMV related IRIS. This is the first reported case where IRIS has presented with CMV polyradiculoneuropathy and bone marrow dysplasia. We would like to highlight that in today's era of HIV care, clinicians should be aware of the possibility of multiorgan involvement by CMV, for appropriate management of this disease in the background of AIDS.

This paper investigates whether aid flows to developing countries fit well with their development priorities. In particular, we examine aid allocation across sectors in a given recipient country by using sectoral data on aid and indicators that measure the recipient's need for aid in each sector. The data show that inter-recipient aid allocation reflects the recipient's need. However, we found no evidence that inter-sectoral allocation fits with national priorities except in high- and middle-...

Although highly active antiretroviral therapy (HAART) has greatly improved the life expectancy of HIV/AIDS patients, the treatment is not curative. It is a global challenge which fosters an urgent need to develop an effective drug or neutralizing antibody delivery approach for the prevention and treatment of this disease. Due to the low density of envelope spikes with restricted mobility present on the surface of HIV virus, which limit the antibody potency and allow virus mutation and escape from the immune system, it is important for a neutralizing antibody to form bivalent or multivalent bonds with the virus. Liposome constructs could fulfil this need due to the flexible mobility of the membrane with its attached antibodies and the capacity for drug encapsulation. In this study, we evaluated the neutralization activity of a range of liposome formulations in different sizes coated with anti-gp120 llama antibody fragments (Vhhs) conjugated via either non-covalent metal chelation or a covalent linkage. The non-covalent construct demonstrated identical binding affinity to HIV-1 envelope glycoprotein gp120 and neutralizing ability for HIV virus as free Vhh. Although covalently linked Vhh showed significant binding affinity to gp120, it unexpectedly had a lower neutralization potency. This may be due to the comparability in size of the viral and liposome particles restricting the number which can be bound to the liposome surface so involving only a fraction of the antibodies, whereas non-covalently attached antibodies dissociate from the surface after acting with gp120 and free the remainder to bind further viruses. Covalently conjugated Vhh might also trigger the cellular uptake of a liposome-virion complex. To explore the possible ability of the antibody-coated liposomes to have a further function, we encapsulated the hydrophobic antiviral drug dapivirine into both of the non-covalently and covalently conjugated liposome formulations, both of which revealed high
