Squires K, Kityo C, Hodder S, et al. Elvitegravir (EVG)/cobicistat (COBI)/emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) is superior to ritonavir (RTV) boosted atazanavir (ATV) plus FTC/TDF in treatment naive women with HIV-1 infection (WAVES study).
What are the guidelines for the treatment of HIV infection?
Patients should understand the goals of treatment and be willing to initiate therapy. Baseline resistance testing is recommended for all patients, but initiating therapy prior to availability of the results may be appropriate in some cases.

What is the goal of antiretroviral therapy for an HIV patient?
The guidelines state that the primary goals of antiretroviral therapy are to maintain maximal suppression of the viral load (i.e., fewer than 50 copies per mL), restore or preserve immunologic function, improve quality of life and reduce HIV-related morbidity and mortality.
What are the five goals of antiretroviral therapy?
Thus, once initiated, ART should be continued, with the following key treatment goals:Maximally and durably suppress plasma HIV RNA;Restore and preserve immunologic function;Reduce HIV-associated morbidity and prolong the duration and quality of survival; and.Prevent HIV transmission.
What is the target of antiretroviral therapy?
Current targets for antiretroviral therapy (ART) include the viral enzymes reverse transcriptase and protease. The use of a combination of inhibitors targeting these enzymes can reduce viral load for a prolonged period and delay disease progression.
What is antiretroviral treatment and what are the benefits?
Antiretroviral therapy (ART) is the treatment for the human immunodeficiency virus (HIV) infection using a combination of Antiretroviral (ARV) drugs. ARV drugs do not 'kill' HIV virus but prevents HIV virus from multiplying and destroying infection fighting CD4 (soldier of the body) cells.
Which are the two main goals of antiretroviral therapy ART )?
Introduction. The primary goal of antiretroviral therapy (ART) is to prevent HIV-associated morbidity and mortality.
Which is usually the most important consideration in the decision to initiate antiretroviral therapy?
[17,18] Regardless of CD4 cell count, the decision to initiate ART should always include consideration of any co-morbid conditions, the willingness and readiness of the patient to initiate therapy, and the availability of resources.
What are the classes of antiretroviral drugs?
Classes of antiretroviral agents include the following:Nucleoside or nucleotide reverse transcriptase inhibitors (NRTIs)Protease inhibitors (PIs)Nonnucleoside reverse transcriptase inhibitors (NNRTIs)Fusion inhibitors.CCR5 co-receptor antagonists (entry inhibitors)HIV integrase strand transfer inhibitors.
What is the importance of antiretroviral therapy?
Effective antiretroviral therapy is the most important intervention in terms of improving longevity and preventing opportunistic infections in patients with human immunodeficiency virus (HIV) infection. Therapy should involve combinations of drugs recommended by current guidelines.
What is the next step in the HIV-1 life cycle?
Formation of Infectious Virons by HIV Proteases –After successful integration of viral DNA into the host genome and formation of proviral proteins, the next step of the HIV-1 life cycle is the cleavage of these polyproteins and formation of infectious virions.
What happens after HIV enters the cell?
Reverse Transcription– After cell entry as HIV is a retrovirus, the virus’s RNA template transcribes into a double-stranded viral DNA in the presence of the enzyme reverse transcriptase. Integration –The viral double-stranded DNA produced after reverse transcription is then transported into the cellular nucleus.
What cells do HIV enter?
HIV virions enter the CD4+ T- cells and utilize the CD4 cells as the machinery for reproduction of new virions. The currently approved antiretroviral drugs aim at halting viral replication at 6 different stages of the HIV life cycle. Table 2lists the drugs approved by the FDA within each drug class. Table 2.
How long does it take for rash to occur with Darunavir?
Rash occurred in 10% patients treated with darunavir and occurred within the first 4 weeks of therapy. Hepatotoxicity, namely acute hepatitis has also been associated with darunavir use in both clinical trials (0.5%) and in post marketing reports.
How many active agents should be in a drug resistance regimen?
a combination regimen should consist of preferably 3 (but at least 2) active agents based on genotype resistance test results.
Why are older drugs no longer used?
Several of the older agents are no longer used in clinical practice, as they are replaced by newer drugs that are more potent, less toxic, with lower pill burden, and less dosing frequency. This large armamentarium of drugs provides the clinicians with ample options to individualize therapy.
Does raltegravir increase or decrease UGT1A1?
Its concentrations may increase/decrease if given with concomitantly with potent inhibitors or inducers of UGT1A1, such as rifampin. It is excreted into both feces (51%) and urine (32%) as unchanged drug. Raltegravir is well tolerated with the most common side effects reported being headache, nausea, and fatigue.
What are the goals of antiretroviral therapy?
Goals of Antiretroviral Therapy. The guidelines state that the primary goals of antiretroviral therapy are to maintain maximal suppression of the viral load (i. e., fewer than 50 copies per mL), restore or preserve immunologic function, improve quality of life and reduce HIV-related morbidity and mortality. While a reduction in plasma viremia ...
What factors are considered when changing antiretroviral therapy?
The guidelines stress that the decision to change the antiretroviral regimen requires consideration of such factors as HIV RNA and CD4 levels and the changes in these measurements, the remaining treatment options in terms of potency, potential resistance patterns from previous antiretroviral therapy and the possibility of side effects, drug interactions, dietary requirements and the need to alter concomitant medications. According to the guidelines, the need to change therapy may arise in three different situations: (1) incomplete suppression of the viral load despite potent antiretroviral therapy, (2) a return of detectable HIV RNA after having achieved undetectable viremia with potent antiretroviral therapy and (3) persistently detectable viremia despite potent combination antiretroviral therapy.
How many CD4 cells are needed for antiretroviral therapy?
In general, antiretroviral therapy should be offered to any patient with fewer than 500 CD4 cells per mm 3 or more than 10,000 copies of HIV RNA per mL by bDNA assay or more than 20,000 copies per mL by RT polymerase chain reaction. Two measurements of the CD4 and HIV RNA are recommended to ensure accuracy of the test results.
How long does it take for HIV to decrease?
In most patients, a large decrease in the viral load should occur after two to eight weeks of therapy. The viral load should continue to decline, with the levels becoming undetectable (less than 50 HIV RNA copies per mL) after 16 to 20 weeks of therapy.

What is a strongly recommended agent?
Strongly recommended agents are those that the panel members believe can accomplish many of the therapeutic goals while causing minimal negative effects on quality of life. Drugs that are effective in viral suppression but greatly interfere with quality of life are now categorized as “recommended as alternatives.”.
