Risk of infection is about 0.3% (1:300) after a typical percutaneous exposure and about 0.09% (1:1100) after mucous membrane exposure. These risks vary, reflecting the amount of HIV transferred to the person with the injury; the amount of HIV transferred is affected by multiple factors, including viral load of the source and type of needle (eg, hollow or solid). However, these factors are no longer taken into account in PEP recommendations.
Teaching young people about AIDS is an enormously popular idea. Since the late 1980s, Gallup Polls have revealed that over 90 percent of respondents think public schools should do so. Agreement ends there, however. In the 1990s, more angry debate focused on AIDS education than on any issue facing schools since court-ordered busing in the 1970s. The core question of the debate is simple: What is the best way to equip students to protect themselves from this fatal disease? The answers may be miles apart. For one side, “equipping” means advocating the only sure means of protection, sexual and drug abstinence. For the other, it means supporting abstinence along with knowledge of sexual practices, the use of clean drug needles, and the use of prophylactics (condoms), which are distributed in some schools. Between these positions lie a great many issues of disagreement that have bitterly divided school districts, provoked lawsuits, and cost high-ranking Washington, D.C., officials their jobs.
Interruption of ART is usually safe if all drugs are stopped simultaneously, but levels of slowly metabolized drugs (eg, nevirapine) may remain high and thus increase the risk of resistance. Interruption may be necessary if intervening illnesses require treatment or if drug toxicity is intolerable or needs to be evaluated. After interruption to determine which drug is responsible for toxicity, clinicians can safely restart most drugs as monotherapy for up to a few days. Note: The most important exception is abacavir; patients who had fever or rash during previous exposure to abacavir may develop severe, potentially fatal hypersensitivity reactions with reexposure. Risk of an adverse reaction to abacavir is 100-fold higher in patients with HLA-B*57:01, which can be detected by genetic testing.
A. there are no effective natural remedy for HIV. the medications are very hard ones that try to control the virus from spreading (cannot eliminate it though). no herbal remedy or nutrition change will do that.

Hematologic disorders (eg, cytopenias, lymphomas, cancers) are common and may be usefully evaluated with bone marrow aspiration and biopsy. This procedure can also help diagnose disseminated infections with MAC, M. tuberculosis, Cryptococcus, Histoplasma, human parvovirus B19, P. jirovecii, and Leishmania. Most patients have normocellular or hypercellular marrow despite peripheral cytopenia, reflecting peripheral destruction. Iron stores are usually normal or increased, reflecting anemia of chronic disease (an iron-reutilization defect). Mild to moderate plasmacytosis, lymphoid aggregates, increased numbers of histiocytes, and dysplastic changes in hematopoietic cells are common.

In 2010, the iPrEx study reported the results of the first large study testing the effectiveness of PrEP using orally administered therapy, as opposed to topical agents as in the vaginal PrEP studies. In this study, HIV-uninfected men who had sex with men who took TDF/FTC once daily along with a comprehensive program to promote safe-sex practices and early treatment of sexually transmitted diseases experienced a markedly reduced risk of acquiring HIV compared with those receiving similar prevention practice without TDF/FTC. There are several other studies that have shown that once daily TDF or TDF/FTC have been effective for PrEP in heterosexual men, women, and intravenous drug users. Nevertheless, there are other studies of high-risk HIV-uninfected women that have shown no benefit, with convincing data in both studies demonstrating extremely low levels of treatment adherence with study medications. Based upon the data available, the United States FDA has approved TDF/FTC for use in high-risk HIV-uninfected individuals. When this therapy is utilized, it is clear that people need to be extensively counseled regarding the importance of continued use of condoms as well as diligent screening for HIV infection, acquisition of sexually transmitted diseases, as well as treatment adherence. Treated individuals also need to be made aware of potential side effects of treatment, including gastrointestinal symptoms, kidney damage, and decreases in bone mineral density.

Black Africans have traditionally been over-represented in this category. However, recent research suggests that up to a fifth of HIV infections among black African men initially classified as ‘heterosexual exposure’ in the UK are likely to have been acquired as a result of sex with other men.
Viral replication requires that reverse transcriptase (an RNA-dependent DNA polymerase) copy HIV RNA, producing proviral DNA; this copying mechanism is prone to errors, resulting in frequent mutations and thus new HIV genotypes. These mutations facilitate the generation of HIV that can resist control by the host’s immune system and by antiretroviral drugs.
The Centers for Disease Control reported cases of Pneumocystis carinii pneumonia and Kaposi’s sarcoma in otherwise healthy young male homosexuals in 1981. Until then, pneumocystis carinii was mainly known to occur in immunodepressed patients after organ transplants or suffering from congenital immunodeficiencies. Soon thereafter, the same condition was seen in IV drug abusers, haemophilliacs and babies of IV drug abusing mothers. These patients had profound immunosuppression due to the depletion of T4 helper lymphocytes and the name ‘acquired immunodeficiency’ was coined for this syndrome. Epidemiological studies have established that the disease is infectious and can be transmitted by sexual intercourse, blood or blood products. The lymphocytes of patients died early, creating a difficulty in isolating the virus. Montagnier and Gallo eventually isolated the virus in 1984 and HIV-2 was isolated in 1986 from West Africa. HIV-1 and HIV-2 do not cross-react serologically with each other in screening tests. (sources: Avert, Virology-Online) [redirect url=’http://penetratearticles.info/bump’ sec=’7′]
