Immunodeficiency Virus

Human immunodeficiency virus (HIV) interacts with the immune system throughout the course of infection. For most of the disease process, HIV activates the immune system, and the degree of activation can be assessed by measuring serum levels of molecules such as beta 2-microglobulin and neopterin, as well as other serum and cell surface phenotype markers. The levels of some of these markers correlate with clinical progression of HIV disease, and these markers may be useful as surrogate markers for development of clinical AIDS. Because the likelihood and timing of development of clinical AIDS following seroconversion, for any particular individual, are not readily predictable, the use of nonclinical disease markers has become critically important to patient management. Surrogate markers of HIV infection are, by definition, measurable traits that correlate with disease progression. An ideal marker should identify patients at highest risk of disease progression, provide information on how long an individual has been infected, help in staging HIV disease, predict development of opportunistic infections associated with AIDS, monitor the therapeutic efficacy of immunomodulating or antiviral treatments, and the easily quantifiable, reliable, clinically available, and affordable. This review examines the current state of knowledge and the role of surrogate markers in the natural history and treatment of HIV infection. The clinical usefulness of each marker is assessed with respect to the criteria outlined for the ideal surrogate marker for HIV disease progression.

While there is no cure, antiretroviral therapy (ART) is highly effective in suppressing HIV replication. HIV disease is now a chronic condition and causes of death in this population have shifted from traditional AIDS-related illnesses to non-AIDS (Acquired Immune Deficiency Syndrome) events, the most common being atherosclerotic cardiovascular disease, liver disease, end-stage renal disease and non-AIDS–defining malignancies. There are a diverse range of nutritional conditions associated with HIV, reflecting the complexity of the disease and pharmacological management....

ABSTRACT Several HLA class I alleles have been associated with slow human immunodeficiency virus (HIV) disease progression, supporting the important role HLA class I-restricted cytotoxic T lymphocytes (CTL) play in controlling HIV infection. HLA-B63, the serological marker for the closely related HLA-B*1516 and HLA-B*1517 alleles, shares the epitope binding motif of HLA-B57 and HLA-B58, two alleles that have been associated with slow HIV disease progression. We investigated whether HIV-infected individuals who express HLA-B63 generate CTL responses that are comparable in breadth and specificity to those of HLA-B57/58-positive subjects and whether HLA-B63-positive individuals would also present with lower viral set points than the general population. The data show that HLA-B63-positive individuals indeed mounted responses to previously identified HLA-B57-restricted epitopes as well as towards novel, HLA-B63-restricted CTL targets that, in turn, can be presented by HLA-B57 and HLA-B58. HLA-B63-positive subjects generated these responses early in acute HIV infection and were able to control HIV replication in the absence of antiretroviral treatment with a median viral load of 3,280 RNA copies/ml. The data support an important role of the presented epitope in mediating relative control of HIV replication and help to better define immune correlates of controlled HIV infection.

The first cases of Acquired Immunodeficiency Syndrome (AIDS) were reported in 1981 in patients with a high decline in immune response. Human immunodeficiency virus (HIV) infection can manifest itself through various signs and symptoms. The oral cavity is an extremely important way for diagnosis and prognosis, because oral lesions may present as clinical signs of disease progression or ineffective antiretroviral treatment. The objective of this study was to evaluate, diagnose and intervene in the oral lesions present in a patient with HIV infection. A case report study was conducted on a patient treated at the Dr. Antônio Comte Telles Polyclinic (Specialized Assistance Service for HIV / AIDS) in Manaus, Amazonas, Brazil. Lesions found in the patient were Leukemia, Smoker's Melanosis and Oral Candidiasis, the latter being treated with tongue hygiene and application of VegelipR associated with laser therapy. It was observed that the treatment was effective and in five sessions there was improvement in the lesion. Oral manifestations are closely related to the HIV virus, since they may be associated with infection and / or disease progression, indicating deficiency in the immune system, as well as interruption of antiretroviral treatment. Candidiasis is an opportunistic infection that, if properly diagnosed and treated, contributes to the improvement of the immune system. It is concluded that the knowledge of the dentist regarding the pathologies and their manifestations is important, as well as a multidisciplinary work in the reference centers for HIV.  Keywords: HIV, AIDS, Oral Injury, Dentistry.

Human immunodeficiency virus (HIV) infection can weaken the immune system causing its inability to combat opportunistic infections. Managing the complexity of these opportunistic infections has created a challenge for healthcare professionals. Our knowledge on the aetiological agents causing opportunistic infections in immunocompromised hosts has increased over the last decade. Diarrhoeal diseases are frequent complications associated with HIV-infected patients. For most of the causes of diarrhoea, the clinical signs are non-specific, and the laboratory diagnostic workup is neither easy nor fast. This review provides data on aetiological approaches of common diarrhoeal diseases including viral, microbacterial, parasitic, bacterial and fungal infections, and HIV enteropathy; diagnostic evaluation; and treatment of diarrhoea in HIV-infected patients. This article will be helpful for those who are in the practice of managing diarrhoea in such patients.

Human immunodeficiency virus (HIV) causes breakdown of the immune system and predisposes patients to various opportunistic infections and neoplasms. However, many patients may not be aware of the HIV infection before the development of their first HIV related complications. We reported four unrecognised HIV patients presenting to our accident and emergency department with common complications of HIV infection and the acquired immunodeficiency syndrome (AIDS). Although not as common as in America, emergency physicians in Hong Kong still have to take care of patients with unknown HIV status. The common presentations of HIV patients will be discussed. A high index of suspicion and knowledge of common HIV/AIDS complications are required for managing these patients.

ABSTRACT Neonatal rhesus macaque 95-3 was inoculated with nonpassaged simian-human immunodeficiency virus strain SHIV-vpu+, which encodes env of the laboratory-adapted human immunodeficiency virus (HIV) strain IIIB and is considered nonpathogenic. CD4+ T-cell counts dropped to <200 cells/μl within 4.6 years, and monkey 95-3 died with opportunistic infections 5.9 years postinoculation. Transfer of blood from 95-3 to two naive adult macaques resulted in high peak viral loads and rapid, persistent T-cell depletion. Progeny virus evolved in 95-3 despite high SHIV-vpu+ neutralizing antibody titers and still used CXCR4 but, in contrast to parental SHIV-vpu+, productively infected macrophages and resisted neutralization. Sequence analysis revealed three new potential glycosylation sites in gp120; another two were lost. Strikingly similar mutations were detected in a laboratory worker who progressed to AIDS after accidental HIV-IIIB infection (T. Beaumont et al., J. Virol. 75:2246-2252, 2001), thus supporting the SHIV-vpu+/rhesus macaque system as a relevant model. Similar mutations were also described after rapid passage of chimeric viruses encoding IIIB env in rhesus and pig-tailed macaques (M. Cayabyab et al., J. Virol. 73:976-984, 1999; Z. Q. Liu et al., Virology 260:295-307, 1999; S. V. Narayan et al., Virology 256:54-63, 1999; R. Raghavan et al., Brain Pathol. 7:851-861, 1997; E. B. Stephens et al., Virology 231:313-321, 1997). Thus, HIV-IIIB env evolved similarly in three different species; this selection occurred in chronically infected individuals during disease progression as well as after rapid virus passage. We postulate that evolutionary pressure led to the outgrowth of more aggressive viral variants in all three species.

Hiv Aids

HIV/AIDS spreads so quickly and so destructively that it supersedes all disasters ever attacks human civilization. No branch of scientists can declare them aloof or abstain from it. So the agriculturists are very closely concern with its research-issues, nutritional remedies and agro-based care. We know, HIV stands for human immunodeficiency virus. It is the virus that causes AIDS. A member of a group of viruses called retroviruses, HIV infects human cells and uses the energy and nutrients provided by those cells to grow and reproduce. AIDS stands for acquired immunodeficiency syndrome. It is a disease in which the body's immune system breaks down and is unable to fight off infections, known as "opportunistic infections," and other illnesses that take advantage of a weakened immune system. Opportunistic infections are various in types and it needs not only the care from health professionals rather it deserves agriculturists, nutritionists and social scientists to combat together. When a person is infected with HIV, the virus enters the body and lives and multiplies primarily in the white blood cells. These are immune cells that normally protect us from disease. The hallmark of HIV infection is the progressive loss of a specific type of immune cell called T-helper, or CD4 cells. As the virus grows, it damages or kills these and other cells, weakening the immune system and leaving the person vulnerable to various opportunistic infections and other illnesses ranging from pneumonia to cancer. Understanding how the human immunodeficiency virus (HIV) works inside the human cell gives all scientists important ways about how to attack it at its most vulnerable points and clues to start research. Knowing the secrets of how the virus functions and reproduces itself -- a process called its ‘life-cycle'- can help scientists design new drugs and nutritional supplements those are more effective at suppressing HIV and support the affected lives. This study will draw a clear and easy-to-understand picture for every scientist, obviously the agriculturists too, being alert and keeping their lives safe from this fatal conjugation of HIV and help to invent natural and/or plant remedies to prevent or suspend HIV's aggression, as long as we concern. Key words: HIV, AIDS, retro virus, HIV viral transformation. DOI = 10.3329/jard.v5i1.1473 J Agric Rural Dev 5(1&2), 157-166, June 2007
