Combinations of antiretroviral nucleoside reverse transcriptase inhibitors, and methods for their use in treating retroviral infections, are provided. In one embodiment, the combinations include non-thymidine nucleoside antiretroviral agents, such as tenofovir-DF, abacavir, APD and DAPD, that select for the K65R mutation and relatively low doses of zidovudine (AZT) or other thymidine nucleoside antiretroviral agents. The thymidine nucleoside antiretroviral agents retard development of the K65R mutation, and at the low doses, are less likely to produce side effects. In another embodiment, the combinations include DAPD and AZT. DAPD retards the development of TAMs, and AZT retards the development of the K65R mutation. In a third embodiment, the combinations include adenine, cytosine, thymidine, and guanine nucleoside antiviral agents, in further combination with at least one additional antiviral agent that works via a different mechanism than a nucleoside analog. This combination has the potential to eliminate the presence of HIV in an infected patient.

A novel single-cell-level phenotypic assay is described, which can simultaneously analyze HIV-1 drug susceptibility and intrinsic replication capacity. This allows quantitative dissection of the functions of antiretroviral drugs into suppression of viral replication and selection of resistant viruses with diminished replication capacities. The disclosed assay provides a tool for the rational evaluation of treatment decisions for patients failing antiretroviral therapy and is expected to be an important part in clinical management of HIV.

A method of treating or preventing SHIV or HIV infection in a subject comprising administering a therapeutically effective amount of a antisense IL-4. The antisense IL-4 inhibits viral replication in the liver, lungs, spleen, and even the lymph nodes of the subject. Further, the antisense IL-4 can be used in combination with other antiretroviral agents or vaccines.

The invention relates to an antibody, a fragment or a derivative thereof, for use as an antiretroviral drug targeting a virus belonging to human endogenous retroviruses type W (HERV-W), wherein said antibody, fragment or derivative thereof is directed against HERV-W Envelope protein (HERV-W Env). The invention also relates to a composition comprising said antibody and a retroviral reverse-transcriptase inhibitory drug, for use as an antiretroviral drug targeting a virus belonging to HERV-W.

A method for the prevention or treatment of human immunodeficiency virus infection by administering an effective amount of amifostine, phosphonol, or similar compound to an individual in need is provided.

Human Immunodeficiency virus causes depletion of CD4 cells. The depletion of CD4 cells results in decrease in immunity of an infected individual. Due to decrease immunity various opportunistic infections occur. These infections are cause for morbidity and mortality in HIV infected individuals. The treatment of HIV these includes antiretroviral drugs. These drugs have their own side effects and immune reconstitution achieved is delayed and slow. Various attempts have been made to improve CD4 count, use of IL-2 is one of them. It is associated with systemic side effects during the period of its administration. The present invention provides method of using mycobacterium w for the management of HIV. According to present invention mycobacterium w when given intradermally is effective in prophylaxis and treatment of AIDS or AIDS related complex (ARC). It is found to improve immunity as well as CD4 count. It is found to eliminate symptoms like fever, diarrhea. The effect is seen even when no antiretrovirals are used.

The present invention relates to pharmaceutical antiretroviral compositions comprising a combination of antiretroviral agents, the manufacturing process thereof and use of the said compositions for the prevention, treatment or prophylaxis of diseases caused by retro viruses, specifically acquired immune deficiency syndrome or an HIV infection.

Disclosed is a method for treating infection with a pathogen. The method involves administration of: (1) a substance which induces active pathogen replication in a cell latently infected with HIV and (2) an anti-pathogen drug. Also disclosed are methods for expanding CD4+ T cells from peripheral blood mononuclear cells isolated from human subjects in the presence of an antiretroviral drug and for treating HIV infection by infusing the expanded CD4+ cells into HIV-infected patients.

Provided herein are nanoparticles and methods for using nanoparticles. The nanoparticles include at least three antiretroviral agents. When introduced to cells the nanoparticles cause an increase in the intracellular concentration of the antiretroviral agents to a level that is at least the IC50 against HIV-I or HIV-2. This concentration may be maintained for at least 21 days after the cells are contacted with the nanoparticle. When administered to a subject the nanoparticles cause the concentration of the antiretroviral agents to increase to at least 100 ng / ml in the serum of the subject, at least 0.5 μg / gram tissue in an organ of the subject, or a combination thereof. Such a concentration may be maintained for at least 21 days after the administration.

The present invention provides a method of predicting the risk of a patient for developing cutaneous adverse drug reaction to non-nucleoside reverse transcriptase inhibitors such as nevirapine by using HLA-B*3505 allele and / or polymorphisms in the CCHCR1 gene.

The present invention provides a pharmaceutical solid oral sprinkle composition comprising one or more antiretroviral drugs, and a method of manufacturing the same. The present invention is particularly useful for treatment of an HIV infection, AIDS related complex, or AIDS.

The present invention relates to methods of monitoring, via polymerase chain reaction, the clinical progression of human immunodeficiency virus infection and its response to antiretroviral therapy. According to the invention, polymerase chain reaction assays may be used to predict immunological decline and to identify, at an early stage, patients whose infection has become resistant to a particular antiretroviral drug regimen.

The present invention relates to pharmaceutical antiretroviral compositions comprising a combination of antiretroviral agents (darunavir, dolutegravir and ritonavir), the manufacturing process thereof and use of the said compositions for the prevention, treatment or prophylaxis of HIV infection.

The invention discloses a novel application of myricetin and derivatives thereof and an anti-HIV infection microbicide. The myricetin can inhibit formation of SEVI, destroy a mature SEVI structure and directly block off HIV infection enhancement caused by the SEVI; and in addition, the myricetin, which also has a good anti-HIV activity, can be developed into the dual-function microbicide capable of antagonizing the SEVI and resisting HIV, so as to prevent possibility that a poor clinical curative effect is caused due to existence of amyloid fibers in seminal fluid to the greatest extent; with the presence of the seminal fluid, the myricetin can coordinate with any one anti-retroviral agent, which is selected from azidothymidine, raltegravir, maraviroc, tenofovir, nevirapine and efavirenz, so as to resist the HIV; the multi-component anti-HIV infection microbicide, which contains the myricetin and the anti-retroviral agent, can be developed; and the microbicide can simultaneously act on two aspects, namely the seminal fluid and viruses, so that a better anti-HIV infection clinical curative effect can be developed.

The invention discloses the use of tripterygium wilfordii in the preparation of a functional drug for curing AIDS. By using high-efficiency antiretroviral drugs combined with tripterygium wilfordii to treat patients from the acute stage of AIDS, no plasma appears within 12 months after the drug is stopped. The rebound of HIV RNA, thus achieving a functional cure for AIDS.
