HIV disclosure among adults living with HIV 总被引:1,自引:0,他引:1
Research on disclosure among heterosexual adult person(s) living with HIV (PLH) was reviewed, omitting disclosure of parental HIV to children. Disclosure has been studied within five additional relational contexts: with partners, family members, friends, healthcare professionals and in work settings. Disclosure is higher among women than men, among Latino and white compared to African-American families, and among younger compared to older HIV-positive adults. Most PLH disclose to their sexual partners and family members, yet there is a significant minority who do not disclose. Similarly, rates of disclosure to employers range from 27-68%, suggesting broad variability in perceived consequences of employment disclosures. Of concern, 40% of PLH do not consistently disclose to their healthcare professionals. Rather than examine HIV disclosures in the context of relationships, it is possible to understand disclosures around personal identity. Disclosure decisions are often made to tell everyone (making HIV status a central attribute of one's identity), no one (requiring strategies for securing social support while remaining anonymous) or some people (requiring strategic decisions based on context). Given that disclosure decisions are central to personal identity, future data on disclosure and interventions designed to increase disclosure or comfort with disclosure must focus on communication strategies adopted by PLH to present a coherent identity. 相似文献

Tuberculosis (TB) is the frequent major opportunistic infection in HIV-infected patients, and is the leading cause of mortality among HIV-infected patients. Genetic susceptibility to TB in HIV negative subjects is well documented. Since coinfections can influence the way in which immune system respond to different pathogens, genetic susceptibility to TB in HIV patients might also change. Studies from India and other parts of the world have shown that genetic susceptibility to TB is influenced by HIV infection. In the present review, we emphasize the role of genetic factors in determining susceptibility to HIV infection, disease progression and development of TB in HIV-infected patients. Polymorphisms in human leukocyte antigen (HLA), MBL2, CD209, vitamin D receptor, cytokine, chemokine and chemokine receptor genes have been shown to be associated with development of TB in HIV patients. However, the results are inconclusive and larger well-defined studies with precise clinical data are required to validate these associations. Apart from candidate gene approach, genome-wide association studies are also needed to unravel the unknown or to establish the previously reported genetic associations with HIV associated TB. Despite the preliminary status of the reported associations, it is becoming clear that susceptibility to development of TB in HIV patients is influenced by both environmental and genetic components. Understanding the genetic and immunologic factors that influence susceptibility to TB in HIV patients could lead to novel insights for vaccine development as well as diagnostic advances to target treatment to those who are at risk for developing active disease. 相似文献

The HIV Prevention Act of 1997 proposes mandatory, confidential reporting of HIV infection, mandatory partner notification, and a provision that would allow providers to refuse to perform invasive treatment to patients who refuse an HIV test. The bill has been endorsed by the American Medical Association, and denounced by AIDS activists as punitive and detrimental to existing HIV prevention efforts. 相似文献

In Spain little research has focused on assessment of health indicators, both physical and psychological, in people living with HIV. The aim of this study is to evaluate a set of different indicators that allow us to identify psychological factors that may be influencing the quality of life of these people. The sample consist of 744 people infected with HIV aged between from 18 to 82 years (M = 43.04; SD = 9.43). Results show that factors such as self-esteem and leading a healthy lifestyle act as protectors in both, physical and mental health. On the other hand, financial problems, body disfigurement, and depressive mood could have harmful effects on both, physical and mental health. The structural model reveals depressed mood as the factor with greatest influence upon mental health, which in turn can be largely explained by factors such as the stress generated by HIV and personal autonomy. This work has allowed us to identify the vulnerability and protective factors that play a significant role in the physical and mental HRQOL of persons with HIV, providing guidelines for design and implementation of psychological intervention programs aimed to improve HRQOL in this population. 相似文献

HIV therapy is able to achieve complete viral suppression in up to 90% of patients. Thus, most patients will benefit from long-term effective and tolerable therapy combinations. Antiretroviral therapy, however, can still lead to side effects, is costly, and its success is dependent on sufficient health system resources and access to different drug combinations. Established tools in prevention and novel approaches to avoid spread of HIV infection are crucial to combat the epidemic. Recent advances in research about how drug regimens stop viral transmission (“treatment as prevention”), how the immune system defends against HIV (natural killer cells, broad neutralizing antibodies), and how cellular factors restrict viral replication are import milestones on the long way to stopping the global epidemic and to fostering vaccine development. 相似文献

In summary, the development of HIV vaccines has progressed from simple first-generation env subunit vaccines to second-generation vaccines containing multiple subunits. Vaccines with epitopes for CMI and Ab responses have broadened the immune response and the potential efficacy of these vaccines. It is hoped that newer technologies including the development of adjuvants, new types of vaccines, such as naked DNA, and new delivery systems, such as liposomes, will evoke stronger immune responses with longer duration. Improved schedules for dosing and combinations of HIV vaccines may result in longer lasting immune responses. A phase III trial is anticipated to begin within the next 2 years. After a temporary lull, the outlook for HIV vaccine development is being met once again with strong enthusiasm and encouragement for the future. 相似文献

Perinatal HIV is often associated with babies, but a large number of children infected perinatally are now 13 to 18 years old. Health care professionals are now looking at the special needs and challenges this group faces. In September 1997, more than 7,000 perinatal AIDS cases were reported in the United States, about one percent of the total number of AIDS cases. Improved treatments increase the likelihood of survival until adulthood. Youth infected at birth are more likely to be at an advanced stage of the illness and often suffer from multiple physical disabilities. They are also more likely to have lost a parent to the disease, and they often find themselves in the role of caretaker with younger siblings. Like children with other chronic illnesses, the perinatally infected miss more school and have more problems managing relationships. Many learn about their infection accidentally and the disclosure can have a serious effect on them. Behavioral problems and counseling approaches for this group are described. 相似文献

Worldwide, 16 cases of HIV-1 superinfection in humans have been reported since 2002. Superinfection is defined as the reinfection of an individual who already has an established infection with a heterologous HIV strain. Controversy exists surrounding superinfection, because it has implications concerning our understanding of worldwide HIV diversity, individual immunity and disease progression, and vaccine development. Here, we review the current understanding of HIV superinfection. 相似文献

Combined antiretroviral therapy results in extraordinary decrease of morbidity and mortality of HIV-infected patients and in an essential change of the HIV/AIDS disease prognosis. However, long-term intake of antiretroviral medicaments is related to occurrence of metabolic and morphological abnormalities, of which some have been combined into a new syndrome--the so called HIV lipodystrophy. The HIV lipodystrophy syndrome covers metabolic and morphological changes. Metabolic changes include dyslipidaemia with hypercholesterolaemia and/or hypertriglyceridaemia, insulin resistance with hyperinsulinaemia and hyperlaktataemia. Morphological changes have the nature of lipoatrophia (loss of subcutaneous fat--on the cheeks, on extremities, on buttocks and marked prominence of surface veins) or lipohypertrophia (growth of fat tissue--on the chest, in the dorsocervical area, lipomatosis of visceral tissues and organs, fat accumulation in the abdominal area). Several HIV lipodystrophy features are very similar to the metabolic syndrome of the general population. That is why this new syndrome represents a prospective risk of premature atherosclerosis and increase of the cardiovascular risk in young HIV positive individuals. The article mentions major presented studies dealing with the relation of antiretroviral treatment and the cardiovascular risk. The conclusions of the studies are not unequivocal--this is, among others, given by the reason that their length is short from the viewpoint of atherogenesis. The major risk of subclinical atherosclerosis acceleration seems to be related to the deep immunodeficiency and low number of CD4+ lymphocytes and florid, uncontrolled HIV infection with a high number of HIV-1 RNA copies actually circulating in the plasma. The question, whether metabolic and morphological changes related to HIV and cART carry a similar atherogenic potential as in the general population, remains open for future. 相似文献

A presentation at the 39th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) noted that people with genital warts have significantly higher levels of semen viral load than those without warts. Genital warts are caused by the human papillomavirus (HPV) and are very common among the general population. Higher levels of HIV in semen may expose partners of HIV-positive men with genital warts to a greater risk of becoming infected. Another session presented statistics showing that rectal gonorrhea is increasing among gay men in New York and Paris, and cautioned that a corresponding increase in HIV rates could follow. Researchers are worried that the increase will include drug resistant strains of the virus. 相似文献
