Integrase inhibitors (INIs) are a class of antiretroviral drug designed to block the action of integrase, a viral enzyme that inserts the viral genome into the DNA of the host cell. Since integration is a vital step in retroviral replication, blocking it can halt further spread of the virus Integrase-Inhibitoren (auch bekannt als Integrase-Strangtransfer-Inhibitoren oder INSTIs) sind eine starke Klasse antiretroviraler Medikamente, die HIV daran hindern, seine genetische Kodierung (Genom) in die DNA der infizierten Wirtszelle zu integrieren. Dies geschieht durch die Blockade eines Enzyms namens Integrase und macht es dadurch für HIV unmöglich, sich zu replizieren
Antiretroviral (ARV) HIV drug class. Integrase strand transfer inhibitors (INSTIs) block integrase (an HIV enzyme). HIV uses integrase to insert (integrate) its viral DNA into the DNA of the host CD4 cell. Blocking integrase prevents HIV from replicating Integrase-Inhibitoren haben antivirale gegen HI-Viren. Sie hemmen die katalytische Aktivität der HIV-Integrase, die als HIV-kodiertes Enzym für die Virusreplikation benötigt wird. Die Integrasehemmung verhindert die Integration des HIV-Genoms in das Wirtszellgenom während der Frühphase der Infektion
Raltegravir is an INSTI integrase inhibitor which inhibits both HIV-1 and HIV-2 replication. It is more potent than other previously known integrase inhibitors as well as causing less side effects. Raltegravir, Elvitegravir, Dolutegravir, and Bictegravir are the only HIV-1 integrase inhibitor being used to treat HIV infections S/GSK1349572 (12)Department of Clinical Infection, Microbiology and Immunology, Institute of Infection and Global Health, University of Liverpool, Liverpool, UK. BACKGROUND: Integrase strand transfer inhibitors (INSTIs) are expected to be widely adopted globally, requiring surveillance of resistance emergence and transmission . EVG is always coadministered with COBI The development of HIV integrase (IN) strand transfer inhibitors (INSTIs) and our understanding of viral resistance to these molecules have been hampered by a paucity of available structural data. We recently reported cocrystal structures of the prototype foamy virus (PFV) intasome with raltegravir and elvitegravir, establishing the general INSTI binding mode. We now present an expanded set of.

Dolutegravir, one of the drugs within the integrase strand transfer inhibitor (INSTI) class, has been recommended by the 2018 WHO ARV guidelines as the preferred first-line ART. 5, 6 Several low- and middle-income countries have already transitioned to dolutegravir and many more are in the planning phase; it is therefore important to report the emergence or transmission of resistance to this. PWH initiating INSTI-based regimens gained, on average, more weight compared to NNRTI-based regimens. This phenomenon may reflect heterogeneous effects of ART agents on body weight regulation that require further exploration.

N2 - Updated guidelines for the treatment of antiretroviral therapy (ART)-negative patients with HIV recommend integrase strand transfer inhibitor (INSTI)-based regimens. HIV patients are tested for resistance to antiretrovirals, and the reported prevalence of transmitted INSTI resistance remains rare worldwide. However, no data related to INSTI resistance in Korean HIV patients have been. Integrase strand transfer inhibitors (INSTIs) Integrase strand transfer inhibitors, often abbreviated to integrase inhibitors, target an enzyme called Integrase, a protein essential for HIV replication. As a result, proviral DNA is unable to insert into the host cell genome. This terminates the life cycle of the virus (see figure on the right). Three INSTIs have been approved by the FDA. A majority of initial and salvage antiretroviral (ARV) regimens for HIV treatment now contain an integrase strand transfer inhibitors (INSTI).

A pretreatment genotype, including integrase sequencing, was obtained and showed three major INSTI mutations: E138A, G140S, and Q148H. These were also demonstrated on a repeat genotype. Subsequent genotypic sequencing of the presumed source patient, an HIV-infected sexual partner, revealed the same integrase mutations, confirming that this almost certainly represented transmitted integrase. Integrase (IN) strand transfer inhibitors (INSTIs) are recent compounds in the antiretroviral arsenal used against HIV. INSTIs work by blocking retroviral inte-gration; an essential step in the viral lifecycle that is catalyzed by the virally encoded IN protein within a nucleoprotein assembly called an intasome.

The proportion of time spent with residual viremia was comparable in the two.
All of our current INSTIs go to the active site of integrase and bind to (chelate) Mg2+. So they basically suck up the supply and leave integrase with none. This becomes an important counseling point for your patients taking INSTIs. Because the drugs are designed to bind to divalent cations, their dosing must be separated from anything with a +2 charge. The biggest players are calcium and. Sub-Saharan African countries are transitioning to dolutegravir-based regimens, even for patients with extensive previous drug exposure, including first-generation integrase strand-transfer inhibitors (INSTI) such as raltegravir. Such exposure might have implications on cross-resistance to dolutegravir-based antiretroviral therapies (ART). We report a 65 years old Cameroonian, previously.
Integrase strand transfer inhibitors (INSTIs) are one of the latest antiretroviral drug classes to be approved for use as part of combination antiretroviral therapy (ART) regimens to control HIV 1.

Wilder: Part of the conclusion in this paper was that there was a small but statistically significant advantage of integrase inhibitors [INSTIs] over the efavirenz and darunavir/ritonavir. Could this information influence what medical providers actually choose for an ART regimen for a newly diagnosed person with HIV? Urbina: Yes, absolutely. These INSTI-based regimens have, throughout the. • Integrase strand transfer inhibitors (INSTIs) are associated with body weight gain, particularly among women living with HIV (WLH)1,2 • Virally-controlled WLH enrolled in the Women's Interagency HIV Study (WIHS) who switched/added an INSTI were more likely to experience clinically significant (≥7%) weight gain compared to women staying on non- INSTI regimens3, but mechanisms remain. Integrase strand transfer inhibitor resistance (InSTI) rates are low. However, genotypic resistance test is not routinely performed in many centres. The aim of this study is to evaluate the prevalence of InSTI related mutations in our large Cohort. We examined all integrase genotypic resistance tests performed as part of routine clinical practice at Spedali Civili General Hospital, University.
Owing to higher potency, better efficacy and tolerability, recently WHO recommended integrase strand transfer inhibitor (INSTI) based first-line antiretroviral therapy (ART). There is lack of INSTI resistance surveillance data from India. Thus, there is a need to analyze integrase (IN) gene from primarily HIV-1 subtype C infected Indian population, before widespread introduction of INSTI in. HIV integrase genes of 13 patients were cloned and replication capacities (RCs) and phenotypic susceptibilities to dolutegravir, raltegravir and elvitegravir were determined with TZM-bl cells. Spearman's correlation coefficient was used to determine cross-resistance between INSTIs. RESULTS: INSTI DRMs were detected in 47% of patients. HIV. A focus of recent research has been metabolic changes associated with integrase strand transfer inhibitor (INSTI)-based ART, but most studies fail to consider other serious clinical outcomes linked to said weight gain. In findings presented at IDWeek 2019, investigators evaluated the impact of initial ART regimen class/drug on incident diabetes mellitus (DM) in a large North American HIV.
The intasome is the basic recombination unit of retroviral integration, comprising the integrase protein and the ends of the viral DNA made by reverse transcription. Clinical inhibitors preferentially target the DNA-bound form of integrase as compared with the free protein, highlighting the critical requirement for detailed understanding of HIV-1 intasome structure and function integrase.
