HIV-associated nephropathy is a late, not early, manifestation of HIV-1 infection. (2/7501)

BACKGROUND: Human immunodeficiency virus-associated nephropathy (HIVAN) can be the initial presentation of HIV-1 infection. As a result, many have assumed that HIVAN can occur at any point in the infection. This issue has important implications for appropriate therapy and, perhaps, for pathogenesis. Since the development of new case definitions for acquired immunodeficiency syndrome (AIDS) and better tools to assess infection, the relationship of HIVAN to the time of AIDS infection has not been addressed. In this study, we reassessed the stage of infection at the time of HIVAN diagnosis in 10 patients, and we reviewed all previously published cases applying the new case definitions to assess stage of infection. METHODS: HIVAN was confirmed by kidney biopsy in HIV seropositive patients with azotemia and/or proteinuria. CD4+ cell count and plasma HIV-1 RNA copy number were measured. We also reviewed all published cases of HIVAN to determine if AIDS-defining conditions, by current Centers for Disease Control definitions, were present in patients with biopsy-proven HIVAN. RESULTS: Twenty HIV-1 seropositive patients with proteinuria and an elevated creatinine concentration were biopsied. HIVAN was the single most common cause of renal disease. CD4+ cell count was below 200/mm3 in all patients with HIVAN, fulfilling Centers for Disease Control criteria for an AIDS-defining condition. HIV-1 plasma RNA was detectable in all patients with HIVAN. In reviewing previous reports, an AIDS-defining condition was present in virtually all patients with HIVAN. CONCLUSION: HIVAN develops late, not early, in the course of HIV-1 infection following the development of AIDS. This likely accounts for the poor prognosis noted in previous publications and has implications for pathogenesis. In addition, given the detectable viral RNA levels, highly active antiretroviral therapy is indicated in HIVAN. Highly active antiretroviral therapy may improve survival as well as alter the natural history of HIVAN.  (+info)

Clinical experience and choice of drug therapy for human immunodeficiency virus disease. (3/7501)

To determine if providers experienced in the management of human immunodeficiency virus (HIV) disease preferred different treatment regimens than providers with less experience, we analyzed data from a national survey of primary care providers' preferred regimens for the management of 30 HIV-related medical conditions. We mailed questionnaires to 999 correct addresses of providers in > 20 cities in the United States in May 1996. We received 524 responses (response rate, 52%). We found a statistically significant association between the number of HIV-infected patients cared for by the provider and the likelihood that the provider would report prescribing highly active antiretroviral therapy and multidrug combinations for treatment of opportunistic infections. Providers with few HIV-infected patients were substantially less likely to report using new therapeutic regimens or new diagnostic tools. We concluded that the preferred regimens of experienced providers are more likely to be consistent with the latest information on treatment for HIV disease than are those of less experienced providers.  (+info)

Issues in the treatment of active tuberculosis in human immunodeficiency virus-infected patients. (4/7501)

Most HIV-infected patients with tuberculosis can be treated satisfactorily with standard regimens with expectations of good results. Treatment of tuberculosis in these patients has been complicated by the introduction of HAART, which relies on drugs that interfere with the most potent class of antituberculous medications. Rifampin-free regimens or regimens that employ rifabutin may be acceptable strategies for patients who are receiving protease inhibitors, although these regimens have not been rigorously evaluated in patients with AIDS. At present, there is good reason to believe that a 6-month course of a rifabutin-containing regimen or a 9-12-month course of a regimen of streptomycin, isoniazid, and pyrazinamide should be adequate therapy for most patients with drug-susceptible disease. As the treatment of HIV infection with antiretroviral agents evolves, the treatment of tuberculosis in patients with AIDS is likely to evolve as well. This will require careful coordination of antituberculosis and antiretroviral therapies.  (+info)

Inhibition of human immunodeficiency virus type 1 replication by combination of transcription inhibitor K-12 and other antiretroviral agents in acutely and chronically infected cells. (5/7501)

8-Difluoromethoxy-1-ethyl-6-fluoro-1,4-dihydro-7-[4-(2-methoxyp hen yl)-1- piperazinyl]-4-oxoquinoline-3-carboxylic acid (K-12) has recently been identified as a potent and selective inhibitor of human immunodeficiency virus type 1 (HIV-1) transcription. In this study, we examined several combinations of K-12 and other antiretroviral agents for their inhibitory effects on HIV-1 replication in acutely and chronically infected cell cultures. Combinations of K-12 and a reverse transcriptase (RT) inhibitor, either zidovudine, lamivudine, or nevirapine, synergistically inhibited HIV-1 replication in acutely infected MT-4 cells. The combination of K-12 and the protease inhibitor nelfinavir (NFV) also synergistically inhibited HIV-1, whereas the synergism of this combination was weaker than that of the combinations with the RT inhibitors. K-12 did not enhance the cytotoxicities of RT and protease inhibitors. Synergism of the combinations was also observed in acutely infected peripheral blood mononuclear cells. The combination of K-12 and cepharanthine, a nuclear factor kappa B inhibitor, synergistically inhibited HIV-1 production in tumor necrosis factor alpha-stimulated U1 cells, a promonocytic cell line chronically infected with the virus. In contrast, additive inhibition was observed for the combination of K-12 and NFV. These results indicate that the combinations of K-12 and clinically available antiretroviral agents may have potential as chemotherapeutic modalities for the treatment of HIV-1 infection.  (+info)

A multiple drug interaction study of stavudine with agents for opportunistic infections in human immunodeficiency virus-infected patients. (6/7501)

The effects of multiple opportunistic infection medications on stavudine pharmacokinetics were evaluated. Ten patients with CD4 counts of less than 200 cells/mm3 received stavudine (40 mg twice daily) in combination with one to three other drugs used to treat opportunistic infections. Serial blood samples for stavudine concentrations were collected after 1 week of therapy on each regimen and assayed for stavudine by using a validated high-pressure liquid chromatography method. Although the maximum concentration of drug in serum was significantly decreased when the drug was given in combination with three opportunistic infection medications, the area under the concentration-time curve did not significantly differ across various treatment regimens. Stavudine exposure was not significantly altered by multiple concomitant medications. Side effects were minor throughout the 3-month study period. The tolerability of stavudine, combined with its lack of drug interactions, makes it an attractive agent for use as part of a combination regimen.  (+info)

Lack of absorption of didanosine after rectal administration in human immunodeficiency virus-infected patients. (7/7501)

The feasibility of rectal administration of didanosine (DDI) was studied in six human immunodeficiency virus-infected patients. After oral intake of a DDI solution (100 mg/m2 of body surface area) combined with an antacid (Maalox), pharmacokinetic parametric values were in accordance with previously published data; the mean +/- standard deviation for terminal half-life was 59.5 +/- 15.0 min, that for peak concentration was 5.2 +/- 3.9 mumol/liter, and that for the area under the time-concentration curve (AUC) was 494 +/- 412 min.mumol/liter. After rectal administration of a similarly prepared DDI solution (100 mg/m2 of body surface area), plasma DDI levels were below the detection limit (0.1 mumol/liter) at all time points in five of the six patients, and in the remaining patient the AUC after rectal application was only 5% of that after oral administration. We conclude that oral administration of DDI cannot be easily replaced by rectal application.  (+info)

Suppression of replication of multidrug-resistant HIV type 1 variants by combinations of thymidylate synthase inhibitors with zidovudine or stavudine. (8/7501)

The replication of recombinant multidrug-resistant HIV-1 clones modeled on clinically derived resistant HIV-1 strains from patients receiving long-term combination therapy with zidovudine (AZT) plus 2',3'-dideoxycytidine was found to regain sensitivity to AZT and stavudine (D4T) as a consequence of a pharmacologically induced decrease in de novo dTMP synthesis. The host-cell system used was phytohemagglutinin-stimulated peripheral blood mononuclear cells; dTMP and dTTP depletion were induced by single exposures to a low level of the thymidylate synthase inhibitor 5-fluorouracil (5-FU) or its deoxynucleoside, 2'-deoxy-5-fluorouridine. The host-cell response to the latter was biphasic: a very rapid decrease in the rate of de novo dTMP formation and, consequently, in intracellular dTTP pools, followed by slower recovery in both indices over 3 to 24 h. With the additional presence of AZT or D4T, however, replication of the multidrug-resistant HIV-1 strains remained inhibited, indicating dependence of HIV DNA chain termination by AZT-5'-monophosphate or 2',3'-didehydro-2', 3'-dideoxythymidine-5'-monophosphate in these resistant strains on simultaneous inhibition of host-cell de novo synthesis of thymidine nucleotides. No effect on viability of control (uninfected) phytohemagglutinin-stimulated/peripheral blood mononuclear cells was noted on 6-day exposures to 5-FU or 2'-deoxy-5-fluorouridine alone or in combination with AZT or D4T, even at drug levels severalfold higher than those used in the viral inhibition studies. These studies may provide useful information for the potential clinical use of AZT/5-FU or D4T/5-FU combinations for the prevention or reversal of multidrug resistance associated with long-term dideoxynucleoside combination therapy.  (+info)

This study compared the efficacy of efavirenz versus ritonavir-boosted protease inhibitor based initial antiretroviral therapy in patients with high plasma
The discovery of medicinal agents capable of specifically inhibiting human immunodeficiency virus (HIV) is urgently needed due to its globally widespread infection. Most of clinically useful anti-HIV agents are nucleosides but their use is limited due to their severe toxicity and emerging drug resistance. More than 50% of world marketed drugs have their origin of the nature. Natural products, of which structural diversity is so broad, are good sources for the effective discovery of anti-HIV agents with decreased toxicity. Over the past decade, substantial progress has been made in research on the natural products for the anti-HIV agents. New natural products that have potent anti-HIV activities with novel structures were reviewed in this article. These compounds, isolated mainly from medicinal plants, in this review have been classified as secondary metabolites such as terpenes, phenolics, and naturally scarce peptides and sugars. Especially, terpenes and phenol substances have gained much ...
HIV-1 infection is associated with B cell dysregulation and dysfunction. In HIV-1-infected patients, we previously reported preservation of intestinal lymphoid structures and dendritic cell maturation pathways after early combination antiretroviral therapy (e-ART), started during the acute phase of the infection, compared with late combination antiretroviral therapy started during the chronic phase. In this study, we investigated whether the timing of combination antiretroviral therapy initiation was associated with the development of the HIV-1-specific humoral response in the gut. The results showed that e-ART was associated with higher frequencies of functional resting memory B cells in the gut. These frequencies correlated strongly with those of follicular Th cells in the gut. Importantly, frequencies of HIV-1 Env gp140-reactive B cells were higher in patients given e-ART, in whom gp140-reactive IgG production by mucosal B cells increased after stimulation. Moreover, IL-21 release by PBMCs stimulated

N2 - Interruption of all antiretroviral therapy for HIV-1 infection when therapy is failing and antiretroviral resistance has emerged is frequently associated with the disappearance of detectable resistance-associated protease and reverse transcriptase substitutions. However, the effect that discontinuation of treatment with a particular antiretroviral class has on resistance to that class when other antiretroviral therapy is continued is unknown. We investigated differences in detectable genotypic resistance to protease inhibitors (PI) and nonnucleoside reverse transcriptase inhibitors (NNRTI) among two populations: patients ...
OBJECTIVES: No randomized controlled trials have yet reported an individual patient benefit of initiating combination antiretroviral therapy (cART) at CD4 counts , 350 cells/muL. It is hypothesized that earlier initiation of cART in asymptomatic and otherwise healthy individuals may lead to poorer adherence and subsequently higher rates of resistance development. METHODS: In a large cohort of HIV-positive individuals, we investigated the emergence of new resistance mutations upon virological treatment failure according to the CD4 count at the initiation of cART. RESULTS: Of 7918 included individuals, 6514 (82.3%), 996 (12.6%) and 408 (5.2%) started cART with a CD4 count ...
The purpose of this study was to find a safe and tolerable dose of the protease inhibitor (PI) atazanavir (ATV), with or without a low-dose boost of the PI ritonavir (RTV), when taken with other anti-HIV drugs in HIV infected infants, children, and adolescents.. Advancements in anti-HIV drugs for HIV infected children and adolescents have been hard to make, in part because these patients often do not take the drugs as prescribed. ATV may be a better option because it is available in the form of powder which children and adolescents may be more willing to take regularly. Using a low dose of RTV as a boosting agent for ATV may also increase the chances of virologic response of highly active antiretroviral treatment (HAART)-experienced patients. This study aimed to find safe and tolerable doses of ATV with or without low-dose RTV boost in infants, children, and adolescents. For this study, participants were enrolled in the United States and South Africa. ...

Objectives: To determine HIV-1 RNA in cerebrospinal fluid (CSF) of successfully treated patients and to evaluate if combination antiretroviral treatments with higher central nervous system penetration-effectiveness (CPE) achieve better CSF viral suppression. Methods: Viral loads (VLs) and drug concentrations of lopinavir, atazanavir, and efavirenz were measured in plasma and CSF. The CPE was calculated using 2 different methods. Results: The authors analyzed 87 CSF samples of 60 patients. In 4 CSF samples, HIV-1 RNA was detectable with 43-82 copies per milliliter. Median CPE in patients with detectable CSF VL was significantly lower compared with individuals with undetectable VL: CPE of 1.0 (range, 1.0-1.5) versus 2.3 (range, 1.0-3.5) using the method of 2008 (P = 0.011) and CPE of 6 (range, 6-8) versus 8 (range, 5-12) using the method of 2010 (P = 0.022).

A systematic review and meta-analysis from China finds that transmitted drug resistance (TDR) - when people who have never been on antiretroviral treatment (ART) before are already resistant to first-line ART - was found at 3% of cases overall, with significant regional variation. The analysis also found this type of drug-resistant HIV has been accelerating in China since 2012, mainly due to resistance to a class of ART known as non-nucleoside reverse transcriptase inhibitors (NNRTI).. The review, published in The Lancets E-Clinical Medicine, analysed 170 studies to assess the level, trend and geographical distribution of HIV drug resistance between 2001 and 2017, and the most common genetic mutations that cause it.. Studies included in this analysis, the most comprehensive of its kind to date, relate to 21,450 people living with HIV who had not been on antiretroviral treatment (ART) before (otherwise known as treatment or ART-naïve), and 30,475 people who had previously been on ...

BOSTON, Feb 11, 2003 (BUSINESS WIRE) --. 48-Week Data from Alize Trial Presented Today at 10th Conference on Retroviruses and Opportunistic Infections. French researchers presented new 48-week data from a Phase III clinical trial today. These data demonstrate that emtricitabine (FTC), an investigational once-daily nucleoside reverse transcriptase inhibitor (NRTI), suppresses HIV when taken as part of a once-daily, protease inhibitor (PI)-sparing antiretroviral regimen. Emtricitabine is being developed by Triangle Pharmaceuticals, which was acquired by Gilead Sciences (Nasdaq:GILD) in January 2003. Dr. Jean-Michel Molina presented the 48-week results of the ANRS 099 Alize trial (Abstract #551) at the 10th Conference on Retroviruses and Opportunistic Infections in Boston, Massachusetts. The ANRS 099 Alize trial is an ongoing three-year, open-label, multicenter study involving 355 patients who at baseline had to have HIV RNA less than 400 copies/mL while receiving PI-based antiretroviral therapy. ...
By several parameters known to be associated with HIV disease progression, children who are treated with protease inhibitor-containing antiretroviral therapy and reconstitute their CD4 T cells despite viral rebound have similar outcomes to those who optimally suppress viral replication. In our study, discordant viral and immune response outcome groups showed sustained increases in CD4 T-cell counts and displayed growth parameters, prevalence of HIV-associated illnesses, and levels of functional immunity that were equivalent to VS/IS children. The substantial restoration of CD4 T-cell counts in the VS/IS and VF/IS response groups during the initial 24 weeks of treatment was sustained over the subsequent 72 weeks in both outcome groups. The durability of CD4 reconstitution in VF/IS children who were enrolled in our study is in contrast to previous examinations of CD4 T-cell reconstitution in HIV-infected adults in which 30% to 40% of patients who displayed discordant viral and immune responses ...

© 2020 The Author(s) Background: Early combination antiretroviral therapy (cART) reduces the size of the viral reservoir in paediatric and adult HIV infection. Very early-treated children may have higher cure/remission potential. Methods: In an observational study of 151 in utero (IU)-infected infants in KwaZulu-Natal, South Africa, whose treatment adhered strictly to national guidelines, 76 infants diagnosed via point-of-care (PoC) testing initiated cART at a median of 26 h (IQR 18-38) and 75 infants diagnosed via standard-of-care (SoC) laboratory-based testing initiated cART at 10 days (IQR 8-13). We analysed mortality, time to suppression of viraemia, and maintenance of aviraemia over the first 2 years of life. Findings: Baseline plasma viral loads were low (median 8000 copies per mL), with 12% of infants having undetectable viraemia pre-cART initiation. However, barely one-third (37%) of children achieved suppression of viraemia by 6 months that was maintained to |12 months. 24% had died or were

The Botswana national treatment guidelines for adults recommend two nucleoside reverse transcriptase inhibitors (NRTIs), zidovudine/lamivudine, and one non-nucleoside reverse transcriptase inhibitor (NNRTI). Typically, the NNRTI is efavirenz or, for women of reproductive age, nevirapine. The regimen consisted of 200 mg of Combivir (lamzid, once available) twice daily. Nevirapine began with a two-week lead-in period of 200 mg once a day followed by a maintenance regimen of 200 mg twice a day. Efavirenz was dosed at 600 mg each day.. Patients experiencing virologic failure on first-line therapy were switched to a protease inhibitor-based regimen (lopinavir/ritonavir) coupled with two NRTIs (didanosine and stavudine or tenofovir or abacavir and lamivudine). When virologic failure occurred with second-line therapy or when there were complicated first-line therapy failures, genotypic resistance testing was undertaken.. At the initial visit, all patients underwent a comprehensive physical examination ...

Objectives: To assess how developing knowledge surrounding combination antiretroviral treatment for people living with HIV infection since mid-1 996 has altered how drugs are used in Australia. Methods: Time trends in use of antiretroviral treatment were calculated on patients recruited to the Australian HIV Observational Database. For each six month period, patients were on one or more antiretroviral drugs for at least two weeks. Other patients were in the no-treatment group. Patients receiving antiretrovirals for more than two weeks were allocated to the category of treatment (mono, double or triple-plus therapy) they received for the longest period. Results: 1476 patients were recruited by September 2000. Of patients currently receiving antiretroviral therapy, 32 per cent took three or more antiretrovirals including an HIV protease inhibitor (PI) and 27 per cent took triple-plus therapy including a nonnucleoside reverse transcriptase inhibitor (NNRTI). The proportion of patients receiving ...
The National Institutes of Health (NIH) has launched a large international trial called IMPAACT 2010 or VESTED to evaluate three antiretroviral treatment regimens in HIV-infected pregnant women.. The trial aims to investigate the safety and efficacy of these regimens in the 639 participants who are 14 to 28 weeks into their pregnancies, along with safety for their infants.. It will compare the existing World Health Organisation (WHO) recommended, first-line maternal efavirenz (EFV) / emtricitabine (FTC) / tenofovir disoproxil fumarate (TDF) regimen with two other regimens containing newer antiretroviral drugs dolutegravir (DTG) or tenofovir alafenamide (TAF).. The mothers viral load at delivery will be measured to compare the virologic efficacy of these three regimens. The viral load is the amount of HIV in the blood.. In addition, effectivity rates of the regimens on adverse pregnancy outcomes will be monitored such as preterm delivery and low infant birth weight, maternal and infant adverse ...

ABSTRACT: BACKGROUND: Structured interruptions of antiretroviral therapy of HIV-1 infected individuals are currently being tested in clinical trials to study the effect interruptions have on the immune responses and control of virus replication. OBJECTIVE: To investigate the potential risks and benefits of interrupted therapy using standard population dynamical models of HIV replication kinetics. METHODS: Standard population dynamical models were used to study the effect of structured therapy interruptions on the immune effector cells, the latent cell compartment and the emergence of drug resistance. CONCLUSIONS: The models suggest that structured therapy interruption only leads to transient or sustained virus control if the immune effector cells increase during therapy. This increase must more than counterbalance the increase in susceptible target cells induced by therapy. The risk of inducing drug resistance by therapy interruptions or the risk of repopulating the pool of latent cells during ...
During the last three decades, HIV/AIDS has become the threat to the world. Almost 75 million people have been infected, and about 36 million people have died of HIV [1]. The introduction of antiretroviral therapy (ART) changes HIV/AIDS from diseases with a high mortality rate to manageable chronic diseases by decreasing the progression of AIDS and reducing HIV-related illness and deaths. Researches revealed that improved access to ART is helping to drive a decline in HIV-related morbidity and mortality [2-5]. In the USA and Canada, a person in his or her 20s who contracts HIV can now expect to live into the 70s if initiated ART early [6].. The standard therapy consists of two nucleoside reverse transcriptase inhibitors (NRTIs) and one non-nucleoside reverse transcriptase inhibitor (NNRTI) [7]. In 2010, these guidelines were revised and recommended less toxic drugs in first-line therapy by replacing stavudine (d4T) with tenofovir (TDF) [8]. In resource-limited countries, World Health ...
BACKGROUND: Etravirine (ETR), a non-nucleoside reverse transcriptase inhibitor (NNRTI) available in France since 2006, is indicated for antiretroviral-experienced HIV-infected adults, in combination with a ritonavir-boosted protease inhibitor (PI). To assess its clinical impact in routine care, we compared hospitalization rates according to ETR + PI prescription or not, among heavily treated HIV-1 infected individuals on failing regimens between 2005 and 2011. METHODS: From the French Hospital Database on HIV (ANRS CO4), we selected heavily treated individuals (prior exposure to at least 2 nucleoside reverse transcriptase inhibitor (NRTI), 2PI and 1 NNRTI) with viral load (VL) | 50 copies/mL who started a new antiretroviral (ARV) regimen between 2005 and 2011. Using an intention-to-continue-treatment approach, hospitalization rates were calculated for the individuals who received ETR + PI, during the months after initiating ETR + PI (ETR + PI) or for the individuals who received ETR + PI, in the
In 2013, WHO published the first consolidated guidelines on the use of antiretroviral (ARV) drugs for HIV treatment and prevention across all age groups and populations. A comprehensive revision of these guidelines based on new scientific evidence and lessons from implementation is being undertaken in 2015.. This early-release guideline makes available two key recommendations that were developed during the revision process in 2015. First, antiretroviral therapy (ART) should be initiated in everyone living with HIV at any CD4 cell count. Second, the use of daily oral pre-exposure prophylaxis (PrEP) is recommended as a prevention choice for people at substantial risk of HIV infection as part of combination prevention approaches. The first of these recommendations is based on evidence from clinical trials and observational studies released since 2013 showing that earlier use of ART results in better clinical outcomes for people living with HIV compared with delayed treatment. The second ...

In previously untreated patients, combinations that include efavirenz compare favorably with regimens that include either other nonnucleoside reverse transcriptase inhibitors or components from other antiretroviral classes.. Two parallel randomized, placebo-controlled Phase III studies in antiretroviral-naive adults compared efavirenz with rilpivirine, each in combination with 2 NRTIs (predominantly tenofovir + emtricitabine). By ITT analysis of pooled data from the 2 studies, 82% of efavirenz recipients and 84% of rilpivirine recipients had HIV RNA levels of ,50 copies/mL at 48 weeks; the difference was not statistically significant. In patients with HIV RNA ,100,000 copies/mL, the efavirenz regimen resulted in higher rates of virologic suppression. The mean increase in CD4 count was 176 cells/µL in the efavirenz group (compared with 192 cells/µL in the rilpivirine group).(13) A randomized trial comparing efavirenz with nevirapine, each given with lamivudine + stavudine in initial therapy, ...
Among 100 children on first-line cART followed for a median 49 months, 34% experienced virologic failure. Twenty-three (68%) of the 34 children with viral failure had detectable resistance mutations, of whom 14 (61%) had multi-class resistance. Fourteen (14%) children were switched to second-line regimens and followed for a median of 28 months. Retrospective analysis revealed that virologic failure had occurred a median of 12 months prior to the switch to second-line. During prolonged first-line treatment in the presence of viral failure, additional resistance mutations accumulated, however, only 1 (7%) of 14 children had persistent viremia during second-line treatment ...
Several studies intensively evaluated the effect of antiretroviral therapy initiated during acute HIV infection has on the size of the cellular reservoir. One such study compared the reservoir as measured by HIV DNA as total, integrated and 2-long terminal repeat (LTR) in those treated during acute infection (n=9), chronic infection (n=26) and amongst elite controllers (n=37) (15). It was not surprising that HIV DNA was detectable regardless of how early therapy was initiated and amongst the elite controllers. Nevertheless, they did find that the levels were significantly lower in those treated during acute infection than during chronic. Moreover, the levels in the early treatment group were similar to the elite controller. While early treatment did not eliminate the reservoir, even amongst those with 10 years of follow-up, it is conceivable that the success of any future strategies to target the reservoir may be more successful in those with a smaller reservoir, such as those initiating therapy ...
We investigated the evolution of HIV reverse transcriptase (RT)- and protease-associated antiretroviral (ARV) drug resistance mutations during the time taken to perform genotypic drug resistance testing. Thirty treatment-experienced patients who were adherent to therapy and who underwent genotypic drug resistance testing provided blood samples at randomization and when reviewing the test results (baseline). Patients remained on their existing therapy between randomization and baseline. The predominant HIV strains in 10 patients (33%) either lost and/or gained primary RT inhibitor (RTI) or protease inhibitor (PI) associated resistance mutations during the testing period. Of the 9 patients with RT mutations, 2 lost, 5 gained, and 2 both lost and gained RTI resistance mutations. One patient gained a significant PI-associated resistance mutation on an existing PI-resistant background. The evolution that occurred in the RT may have altered the effectiveness of subsequent ARV therapy in some patients ...

This combination of antiretrovirals was well-tolerated. Pharmacokinetic values were similar to those observed in a previous study ...
Title: Metabolic and Cardiovascular Complications of Highly Active Antiretroviral Therapy for HIV Infection. VOLUME: 4 ISSUE: 1. Author(s):Giuseppe Barbaro. Affiliation:Viale Anicio Gallo 63,00174 Rome, Italy.. Keywords:Human immunodeficiency virus, highly active antiretroviral therapy, nucleoside reverse transcriptase inhibitors, protease inhibitors, metabolic syndome, cardiovascular disease. Abstract: Highly active antiretroviral therapy (HAART) regimens, especially those including protease inhibitors have been shown to cause, in a high proportion of HIV-infected patients, a metabolic syndrome (lipodystrophy/lipoatrophy, dyslipidemia, type 2 diabetes mellitus, insulin resistance) that may be associated with an increased risk of cardiovascular disease. A careful stratification of the cardiovascular risk of HIVinfected patients under HAART is needed according to the most recent clinical guidelines. ...
2015 Elsevier Ltd. Background Tenofovir disoproxil fumarate can cause renal and bone toxic effects related to high plasma tenofovir concentrations. Tenofovir alafenamide is a novel tenofovir prodrug with a 90% reduction in plasma tenofovir concentrations. Tenofovir alafenamide-containing regimens can have improved renal and bone safety compared with tenofovir disoproxil fumarate-containing regimens. Methods In these two controlled, double-blind phase 3 studies, we recruited treatment-naive HIV-infected patients with an estimated creatinine clearance of 50 mL per min or higher from 178 outpatient centres in 16 countries. Patients were randomly assigned (1:1) to receive once-daily oral tablets containing 150 mg elvitegravir, 150 mg cobicistat, 200 mg emtricitabine, and 10 mg tenofovir alafenamide (E/C/F/tenofovir alafenamide) or 300 mg tenofovir disoproxil fumarate (E/C/F/tenofovir disoproxil fumarate) with matching placebo. Randomisation was done by a computer-generated allocation sequence (block ...

OBJECTIVE: To examine the effect of different antiretroviral treatment regimens on viral load, CD4 lymphocyte counts, and rates of progression to clinical acquired immunodeficiency syndrome events among treatment-naive human immunodeficiency virus (HIV)-infected patients enrolled in a large community cohort study. METHODS: Based in 7 outpatient clinics, the Swiss HIV Cohort Study is a cohort with national coverage. Virological, immunologic, and clinical results of 755 treatment-naive patients (median age, 36 years; 28.2% female) who initiated antiretroviral therapy between July 1, 1995, and June 30, 1997, were analyzed. Patients started undergoing monotherapy with 1 reverse transcriptase inhibitor (RTI), combination therapy with at least 2 RTIs, or highly active antiretroviral therapy (HAART) with RTIs and protease inhibitors. RESULTS: Antiretroviral treatment led to a mean reduction of viremia of 1.8 log10 copies per milliliter with HAART, 1.2 log10 copies per milliliter with RTI comb

N2 - Circulating immune complexes (CIC) were analyzed in a cohort of 30 children infected with the human immunodeficiency virus. Elevated CIC were detected by the C1 q assay in 70% (21/30) of all patients and by the Raji cell assay in 93% (28/30) of all patients. While only less than one third of patients with elevated CIC had free serum antibodies to Epstein-Barr virus, 80% (16/20) of them had detectable antibodies to Epstein-Barr virus associated with CIC. Enriched CIC in human immunodeficiency virus-infected children contained low levels of complement. These findings document that, as an expression of the humoral immunodeficiency, CIC in human immunodeficiency virus-infected children are deficient in complement and can thus be underestimated if complement-precipitating methods are used for their ...

Background: New WHO guidelines recommend initiation of antiretroviral therapy for HIV-positive adults with CD4 counts of 500 cells per μL or less, a higher threshold than was previously recommended. Country decision makers have to decide whether to further expand eligibility for antiretroviral therapy accordingly. We aimed to assess the potential health benefits, costs, and cost-effectiveness of various eligibility criteria for adult antiretroviral therapy and expanded treatment coverage.. Methods: We used several independent mathematical models in four settings-South Africa (generalised epidemic, moderate antiretroviral therapy coverage), Zambia (generalised epidemic, high antiretroviral therapy coverage), India (concentrated epidemic, moderate antiretroviral therapy coverage), and Vietnam (concentrated epidemic, low antiretroviral therapy coverage)-to assess the potential health benefits, costs, and cost-effectiveness of various eligibility criteria for adult antiretroviral therapy under ...
To describe the early response to World Health Organization (WHO)-recommended nonnucleoside reverse transcriptase inhibitor (NNRTI)-based first-line highly active antiretroviral therapy (HAART) in HIV-1-infected Kenyan children unexposed to nevirapine. Observational prospective cohort. HIV-1 RNA level, CD4 lymphocyte count, weight for age z score, and height for age z score were measured before the initiation of HAART and every 3 to 6 months thereafter. Children received no nutritional supplements. Sixty-seven HIV-1-infected children were followed for a median of 9 months between August 2004 and November 2005. Forty-seven (70%) used zidovudine, lamivudine (3TC), and an NNRTI (nevirapine or efavirenz), whereas 25% used stavudine (d4T), 3TC, and an NNRTI. Nevirapine was used as the NNRTI by 46 (69%) children, and individual antiretroviral drug formulations were used by 63 (94%), with only 4 (6%) using a fixed-dose combination of d4T, 3TC, and nevirapine (Triomune; Cipla, Mumbai, India).

Objective: Some HIV patients treated with highly active antiretroviral therapy (HAART) do not resolve their plasma viraemia or HIV RNA can reappear after a period of virological control. We investigate whether polymorphisms in cytokine genes affect the control of plasma HIV RNA over 5 years on HAART. Design: The study utilized adult HIV-infected patients in Western Australia. Plasma HIV-RNA levels were assessed from commencement of HAART in patients who had a CD4 T-cell count less than 100 cells/μl before HAART and achieved immune reconstitution assessed by CD4 T-cell counts. Results: Control of plasma viraemia could be predicted from carriage of allele 2 at position -889 in the IL1A gene (IL1A-889*2). This was significant when assessed by the proportion of patients with a plasma HIV-RNA level of 400 copies/ml or less (P = 0.002). At 48 months post-HAART, proportions were approximately 0.76, 0.51 and 0.32 for IL1A (1,1), (1,2) and (2,2) patients, respectively. The outcome was independent of the ...

Primary HIV-associated thrombocytopenia (PHAT) typically improves with highly active antiretroviral therapy (HAART); however, cases continue to occur. Data comparing the epidemiology of PHAT between the pre-HAART and HAART eras are limited. We retrospectively examined the incidence of PHAT over 28 years in the US Military HIV Natural History Study (NHS) from 1986 to 2013. Subjects had a nadir platelet count |100 × 109/l with no other identifiable cause. Time periods were categorized as pre-HAART (1986-1995), early HAART (1996-2001), and later HAART (2002-2013). Incidence, demographic data, and CD4 count were compared across the three eras. A generalized estimating equations model was used to assess any association of platelet count and HIV viral load in cases diagnosed during the HAART eras. 218 participants met the case definition. 86.2 % of cases occurred prior to 2002. The incidence of PHAT per 1000 person-years of follow-up was 16.3, 4.6, and 1.9 during pre-HAART, early HAART and later HAART eras

Age ,50 years was associated with earlier treatment discontinuation.. ...
We next isolated highly purified populations of resting CD4+ T cells from the peripheral blood of these donors. After depletion of monocytes by adherence, negative selection with monoclonal antibodies and magnetic beads was used to remove CD8+ T cells, B cells, monocytes, and natural killer cells. In addition, activated CD4+ T cells, which represented an average of 10% of the CD4+ T cell populations in these individuals (Table 1), were removed by bead depletion with antibodies to CD25, CD69, and human lymphocyte antigen (HLA)-DR. Additional purification was achieved by flow cytometric sorting of small lymphocytes expressing CD4 but not HLA-DR, which is expressed on all activated T cells. This multistep purification gave populations of resting CD4+ HLA-DR− T cells that were, on average, 97% pure (Table 1). Most importantly, the sorted populations were typically contaminated with ,1% activated CD4+ T cells.. Specialized PCR approaches have shown that a low frequency of resting CD4+ T cells from ...
A pilot longitudinal study was conducted for 3 months on HIV positive and AIDS patients on antiretroviral therapy, at a day care clinic at the Yaoundé Central Hospital, Cameroon, between April and July 2008. A total of 223 HIV patients were recruited following initiation and each patient benefited from pretherapeutic tests. Social-demographic, clinical and biological data were recorded for each subject and finally analyzed using standard statistical procedures. Out of the 223 subjects on highly active antiretroviral therapy (HAART) in the study, 153 were females (68. 6%) and 70 were males (31. 6%). The age group that was most represented was 30 - 39 (37.7%). The mean age of patients was 39.34 ± 11.31 years.
