Late Identification of Perinatal Transmission of HIV in an Infant at High Risk.

The focus of this case study is the delayed diagnosis of a perinatal HIV transmission, which was identified when the infant reached 4 months of age, and the social conditions and structural determinants that contributed to the increased transmission risk. Despite adhering to the diagnostic testing protocols and neonatal antiretroviral (ARV) guidelines of the New York State Department of Health, this transmission still occurred. This transmission event prompted strategies to address criminalization of substance use during pregnancy and a reevaluation of the HIV testing and treatment protocols, including the timing of testing. Obtaining a diagnostic specimen at birth before initiating prophylactic or presumptive therapy, without causing delays in therapy, and incorporating HIV-1 DNA or RNA testing 2 to 6 weeks after discontinuing ARV therapy might have facilitated earlier detection and a quicker resumption of ARV therapy for this high-risk infant. Subsequently, the New York State HIV perinatal testing guidelines were updated. These changes included the recommendation to obtain a diagnostic specimen at birth before initiating ARV medications, whenever feasible, without causing delays in ARV initiation. Additionally, an extra virologic diagnostic test is recommended at 2 to 6 weeks after discontinuing ARVs for infants at high risk of perinatal HIV transmission, especially those with possible DNA or RNA suppression due to ARV prophylaxis or presumptive HIV therapy.

Effectiveness of JYNNEOS Vaccine Against Diagnosed Mpox Infection - New York, 2022.

In 2022, an international Monkeypox virus outbreak, characterized by transmission primarily through sexual contact among gay, bisexual, and other men who have sex with men (MSM), resulted in 375 monkeypox (mpox) cases in the state of New York outside of New York City (NYC).*,† The JYNNEOS vaccine (Modified Vaccinia Ankara vaccine, Bavarian Nordic), licensed by the U.S. Food and Drug Administration (FDA) against mpox as a 2-dose series, with doses administered 4 weeks apart,§ was deployed in a national vaccination campaign.¶ Before this outbreak, evidence to support vaccine effectiveness (VE) against mpox was based on human immunologic and animal challenge studies (1-3). New York State Department of Health (NYSDOH) conducted a case-control study to estimate JYNNEOS VE against diagnosed mpox in New York residents outside of NYC, using data from systematic surveillance reporting. A case-patient was defined as a man aged ≥18 years who received a diagnosis of mpox during July 24-October 31, 2022. Contemporaneous control patients were men aged ≥18 years with diagnosed rectal gonorrhea or primary syphilis and a history of male-to-male sexual contact, without mpox. Case-patients and control patients were matched to records in state immunization systems. JYNNEOS VE was estimated as 1 - odds ratio (OR) x 100, and JYNNEOS vaccination status (vaccinated versus unvaccinated) at the time of diagnosis was compared, using conditional logistic regression models that adjusted for week of diagnosis, region, patient age, and patient race and ethnicity. Among 252 eligible mpox case-patients and 255 control patients, the adjusted VE of 1 dose (received ≥14 days earlier) or 2 doses combined was 75.7% (95% CI = 48.5%-88.5%); the VE for 1 dose was 68.1% (95% CI = 24.9%-86.5%) and for 2 doses was 88.5% (95% CI = 44.1%-97.6%). These findings support recommended 2-dose JYNNEOS vaccination consistent with CDC and NYSDOH guidance.

Assessing the Impact of a PrEP Aware Week Campaign on PrEP Prescription Fills in NYS.

CONTEXT: The New York State (NYS) Department of Health AIDS Institute engaged stakeholders across NYS to participate in the state's first "PrEP Aware Week" (PAW). PAW sought to increase the knowledge, interest, and number of PrEP (pre-exposure prophylaxis) prescriptions filled across NYS. PAW activities were designed to be easy to implement, with minimal cost. Stakeholders were provided activities to implement, along with a social media tool kit featuring videos, graphic ads, and sample social media posts in English and Spanish to use as is or modify. PAW included more than 750 distinct events and activities undertaken by more than 250 participating providers. OBJECTIVE: To assess the impact of PAW on PrEP prescription filling patterns in NYS. DESIGN: An interrupted time-series analysis was conducted to estimate the impact of PAW on overall and new PrEP prescription filling patterns. Separate models were developed by sex (male, female), race and ethnicity (White non-Hispanic, Black non-Hispanic, Hispanic, other, unknown), and region (New York City, rest of NYS). SETTING: PAW took place across NYS during the week beginning October 20, 2019. PARTICIPANTS: PAW was undertaken by more than 250 health care providers, nonmedical health & human services providers, local and state health department staff, and colleges and universities. MAIN OUTCOME MEASURES: The number of overall and new PrEP prescriptions. RESULTS: PAW was associated with modest increases (6%-9%) in the number of PrEP prescription fills in NYS. The PAW impact lasted for about 2 months, generated an estimated 2727 additional PrEP prescription fills statewide, and was realized across sex, region, and racial and ethnic subgroups. Increased prescription fills were driven by those previously prescribed PrEP. Increases in new prescriptions were noted among Latinx individuals (21% increase, 55 additional prescriptions) but not overall or across other groups. CONCLUSION: NYS's PAW was effective at increasing PrEP prescription refills in NYS.

Investigation of Presumptive HIV Transmission Associated with Hospitalization Using Nucleotide Sequence Analysis - New York, 2017.

Since implementation of Standard Precautions* for the prevention of bloodborne pathogen transmission in 1985, health care-associated transmission of human immunodeficiency virus (HIV) in the United States has been rare (1). In October 2017, the New York City Department of Health and Mental Hygiene (NYCDOHMH) and the New York State Department of Health (NYSDOH) were notified by a clinician of a diagnosis of acute HIV infection in a young adult male (patient A) without recognized risk factors (i.e., he was monogamous, had an HIV-negative partner, and had no injection drug use) who had recently been hospitalized for a chronic medical condition. The low risk coupled with the recent hospitalization and medical procedures prompted NYSDOH, NYCDOHMH, and CDC to investigate this case as possible health care-associated transmission of HIV. Among persons with known HIV infection who had hospitalization dates overlapping those of patient A, one person (patient B) had an HIV strain highly similar to patient A's strain by nucleotide sequence analysis. The sequence relatedness, combined with other investigation findings, indicated a likely health care-associated transmission. Nucleotide sequence analysis, which is increasingly used for detecting HIV clusters (i.e., persons with closely related HIV strains) and to inform public health response (2,3), might also be used to identify possible health care-associated transmission of HIV to someone with health care exposure and no known HIV risk factors (4).

Notes from the Field: Increase in Reported Hepatitis A Infections Among Men Who Have Sex with Men - New York City, January-August 2017.

Since 2011, the New York City (NYC) Department of Health and Mental Hygiene (DOHMH) has typically been notified of three or fewer cases of hepatitis A virus (HAV) infection each year among men who have sex with men (MSM) who reported no travel to countries where HAV is endemic. This year, DOHMH noted an increase in HAV infections among MSM with onsets in January-March 2017, and notified other public health jurisdictions via Epi-X, CDC's communication exchange network. As a result, 51 patients with HAV infection involving MSM were linked to the increase in NYC.

Using computer-based monitoring and intervention to prevent harmful combinations of antiretroviral drugs in the New York State AIDS Drug Assistance Program.

BACKGROUND: Despite the growing number of HIV-infected people and the acknowledged complexity of HIV therapy, there are no standard safeguards in the outpatient setting against dangerous antiretroviral (ARV) therapy combinations in the publicly financed arena. METHODS: Using quarterly pharmacy claims data from the New York State AIDS Drug Assistance Program, a three-phase approach was developed: The extent of contraindicated ARV combinations was ascertained; prescriber alerts were developed; and, finally, the reimbursement of contraindicated ARV combinations was blocked at pharmacy. ARV dosages, the number of ARV medications in a regimen, clinical adequacy of the regimen, medication claim denials, clinician adjudication, and subsequent clinician prescribing patterns were analyzed. RESULTS: For the 27-month study period (October 1, 2006-December 31, 2009), 112,383 ARV regimens involving 396,303 ARV medications for 25,463 unique recipients were individually analyzed. A total of 1,089 interventions occurred; denials and interventions increased per quarter from a baseline of 129 to 217 by the study's end. All contraindicated combinations referred for adjudication during the study were upheld. More than 88.3% (range, 87.1% to 89.9%) of regimens per quarter were consistent with effective ARV as promulgated by current guidelines. The targeted dissemination of ARV drug interaction safety alerts to previous prescribers of contraindicated combinations during the first year of the review curtailed the practice by 77.3%. CONCLUSION: A systems-level intervention can be used on a state level to reduce ARV contraindicated medication errors in the outpatient setting through a coordinated approach of prescriber clinical education and electronic pharmacy and billing systems and provides an effective safety and quality monitoring model.

Factors associated with SARS-CoV-2-related hospital outcomes among and between persons living with and without diagnosed HIV infection in New York State.

BACKGROUND: Persons living with diagnosed HIV (PLWDH) are at increased risk for severe illness due to COVID-19. The degree to which this due to HIV infection, comorbidities, or other factors remains unclear. METHODS: We conducted a retrospective matched cohort study of individuals hospitalized with COVID-19 in New York State between March and June 2020, during the first wave of the pandemic, to compare outcomes among 853 PLWDH and 1,621 persons without diagnosed HIV (controls). We reviewed medical records to compare sociodemographic and clinical characteristics at admission, comorbidities, and clinical outcomes between PLWDH and controls. HIV-related characteristics were evaluated among PLWDH. RESULTS: PLWDH were significantly more likely to have cardiovascular (matched prevalence-ratio [mPR], 1.22 [95% CI, 1.07-1.40]), chronic liver (mPR, 6.71 [95% CI, 4.75-9.48]), chronic lung (mPR, 1.76 [95% CI, 1.40-2.21]), and renal diseases (mPR, 1.77 [95% CI, 1.50-2.09]). PLWDH were less likely to have elevated inflammatory markers upon hospitalization. Relative to controls, PLWDH were 15% less likely to require mechanical ventilation or extracorporeal membrane oxygenation (ECMO) and 15% less likely to require admission to the intensive care unit. No significant differences were found in in-hospital mortality. PLWDH on tenofovir-containing regimens were significantly less likely to require mechanical ventilation or ECMO (risk-ratio [RR], 0.73 [95% CI, 0.55-0.96]) and to die (RR, 0.74 [95% CI, 0.57-0.96]) than PLWDH on non-tenofovir-containing regimens. CONCLUSIONS: While hospitalized PLWDH and controls had similar likelihood of in-hospital death, chronic disease profiles and degree of inflammation upon hospitalization differed. This may signal different mechanisms leading to severe COVID-19.

COVID-19 Outcomes Among Persons Living With or Without Diagnosed HIV Infection in New York State.

Importance: New York State has been an epicenter for both the US coronavirus disease 2019 (COVID-19) and HIV/AIDS epidemics. Persons living with diagnosed HIV may be more prone to COVID-19 infection and severe outcomes, yet few studies have assessed this possibility at a population level. Objective: To evaluate the association between HIV diagnosis and COVID-19 diagnosis, hospitalization, and in-hospital death in New York State. Design, Setting, and Participants: This cohort study, conducted in New York State, including New York City, between March 1 and June 15, 2020, matched data from HIV surveillance, COVID-19 laboratory-confirmed diagnoses, and hospitalization databases to provide a full population-level comparison of COVID-19 outcomes between persons living with diagnosed HIV and persons living without diagnosed HIV. Exposures: Diagnosis of HIV infection through December 31, 2019. Main Outcomes and Measures: The main outcomes were COVID-19 diagnosis, hospitalization, and in-hospital death. COVID-19 diagnoses, hospitalizations, and in-hospital death rates comparing persons living with diagnosed HIV with persons living without dianosed HIV were computed, with unadjusted rate ratios and indirect standardized rate ratios (sRR), adjusting for sex, age, and region. Adjusted rate ratios (aRRs) for outcomes specific to persons living with diagnosed HIV were assessed by age, sex, region, race/ethnicity, transmission risk, and CD4+ T-cell count-defined HIV disease stage, using Poisson regression models. Results: A total of 2988 persons living with diagnosed HIV (2109 men [70.6%]; 2409 living in New York City [80.6%]; mean [SD] age, 54.0 [13.3] years) received a diagnosis of COVID-19. Of these persons living with diagnosed HIV, 896 were hospitalized and 207 died in the hospital through June 15, 2020. After standardization, persons living with diagnosed HIV and persons living without diagnosed HIV had similar diagnosis rates (sRR, 0.94 [95% CI, 0.91-0.97]), but persons living with diagnosed HIV were hospitalized more than persons living without diagnosed HIV, per population (sRR, 1.38 [95% CI, 1.29-1.47]) and among those diagnosed (sRR, 1.47 [95% CI, 1.37-1.56]). Elevated mortality among persons living with diagnosed HIV was observed per population (sRR, 1.23 [95% CI, 1.07-1.40]) and among those diagnosed (sRR, 1.30 [95% CI, 1.13-1.48]) but not among those hospitalized (sRR, 0.96 [95% CI, 0.83-1.09]). Among persons living with diagnosed HIV, non-Hispanic Black individuals (aRR, 1.59 [95% CI, 1.40-1.81]) and Hispanic individuals (aRR, 2.08 [95% CI, 1.83-2.37]) were more likely to receive a diagnosis of COVID-19 than White individuals, but they were not more likely to be hospitalized once they received a diagnosis or to die once hospitalized. Hospitalization risk increased with disease progression to HIV stage 2 (aRR, 1.29 [95% CI, 1.11-1.49]) and stage 3 (aRR, 1.69 [95% CI, 1.38-2.07]) relative to stage 1. Conclusions and Relevance: In this cohort study, persons living with diagnosed HIV experienced poorer COVID-related outcomes relative to persons living without diagnosed HIV; Previous HIV diagnosis was associated with higher rates of severe disease requiring hospitalization, and hospitalization risk increased with progression of HIV disease stage.

Evaluation of Algorithms Used for PrEP Surveillance Using a Reference Population From New York City, July 2016-June 2018.

OBJECTIVE: Daily tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) use as HIV preexposure prophylaxis (PrEP) is monitored by identifying TDF/FTC prescriptions from pharmacy databases and applying diagnosis codes and antiretroviral data to algorithms that exclude TDF/FTC prescribed for HIV postexposure prophylaxis (PEP), HIV treatment, and hepatitis B virus (HBV) treatment. We evaluated the accuracy of 3 algorithms used by the Centers for Disease Control and Prevention (CDC), Gilead Sciences, and the New York State Department of Health (NYSDOH) using a reference population in Bronx, New York. METHODS: We extracted diagnosis codes and data on all antiretroviral prescriptions other than TDF/FTC from an electronic health record database for persons aged ≥16 prescribed TDF/FTC during July 2016-June 2018 at Montefiore Medical Center. We reviewed medical records to classify the true indication of first TDF/FTC use as PrEP, PEP, HIV treatment, or HBV treatment. We applied each algorithm to the reference population and compared the results with the medical record review. RESULTS: Of 2862 patients included in the analysis, 694 used PrEP, 748 used PEP, 1407 received HIV treatment, and 13 received HBV treatment. The algorithms had high specificity (range: 98.4%-99.0%), but the sensitivity of the CDC algorithm using a PEP definition of TDF/FTC prescriptions ≤30 days was lower (80.3%) than the sensitivity of the algorithms developed by Gilead Sciences (94.7%) or NYSDOH (96.1%). Defining PEP as TDF/FTC prescriptions ≤28 days improved CDC algorithm performance (sensitivity, 95.8%; specificity, 98.8%). CONCLUSIONS: Adopting the definition of PEP as ≤28 days of TDF/FTC in the CDC algorithm should improve the accuracy of national PrEP surveillance.

Elevated COVID-19 outcomes among persons living with diagnosed HIV infection in New York State: Results from a population-level match of HIV, COVID-19, and hospitalization databases.

BACKGROUND: New York State (NYS) has been an epicenter for both COVID-19 and HIV/AIDS epidemics. Persons Living with diagnosed HIV (PLWDH) may be more prone to COVID-19 infection and severe outcomes, yet few population-based studies have assessed the extent to which PLWDH are diagnosed, hospitalized, and have died with COVID-19, relative to non-PLWDH. METHODS: NYS HIV surveillance, COVID-19 laboratory confirmed diagnoses, and hospitalization databases were matched. COVID-19 diagnoses, hospitalization, and in-hospital death rates comparing PLWDH to non-PLWDH were computed, with unadjusted rate ratios (RR) and indirect standardized RR (sRR), adjusting for sex, age, and region. Adjusted RR (aRR) for outcomes among PLWDH were assessed by age/CD4-defined HIV disease stage, and viral load suppression, using Poisson regression models. RESULTS: From March 1-June 7, 2020, PLWDH were more frequently diagnosed with COVID-19 than non-PLWDH in unadjusted (RR [95% confidence interval (CI)]: 1.43[1.38-1.48), 2,988 PLWDH], but not in adjusted comparisons (sRR [95% CI]: 0.94[0.91-0.97]). Per-population COVID-19 hospitalization was higher among PLWDH (RR [95% CI]: 2.61[2.45-2.79], sRR [95% CI]: 1.38[1.29-1.47], 896 PLWDH), as was in-hospital death (RR [95% CI]: 2.55[2.22-2.93], sRR [95%CI]: 1.23 [1.07-1.40], 207 PLWDH), albeit not among those hospitalized (sRR [95% CI]: 0.96[0.83-1.09]). Among PLWDH, hospitalization risk increased with disease progression from HIV Stage 1 to Stage 2 (aRR [95% CI]:1.27[1.09-1.47]) and Stage 3 (aRR [95% CI]: 1.54[1.24-1.91]), and for those virally unsuppressed (aRR [95% CI]: 1.54[1.24-1.91]). CONCLUSION: PLWDH experienced poorer COVID-related outcomes relative to non-PLWDH, with 1-in-522 PLWDH dying with COVID-19, seemingly driven by higher rates of severe disease requiring hospitalization.

Safety and efficacy of the HIV-1 integrase inhibitor raltegravir (MK-0518) in treatment-experienced patients with multidrug-resistant virus: a phase II randomised controlled trial.

BACKGROUND: Raltegravir (MK-0518) is an HIV-1 integrase inhibitor with potent in-vitro activity against HIV-1 strains including those resistant to currently available antiretroviral drugs. The aim of this study was to assess the safety and efficacy of raltegravir when added to optimised background regimens in HIV-infected patients. METHODS: HIV-infected patients with HIV-1 RNA viral load over 5000 copies per mL, CD4 cell counts over 50 cells per muL, and documented genotypic and phenotypic resistance to at least one nucleoside reverse transcriptase inhibitor, one non-nucleoside reverse transcriptase inhibitor, and one protease inhibitor were randomly assigned to receive raltegravir (200 mg, 400 mg, or 600 mg) or placebo orally twice daily in this multicentre, triple-blind, dose-ranging, randomised study. The primary endpoints were change in viral load from baseline at week 24 and safety. Analyses were done on a modified intention-to-treat basis. This trial is registered with ClinicalTrials.gov, with the number NCT00105157. FINDINGS: 179 patients were eligible for randomisation. 44 patients were randomly assigned to receive 200 mg raltegravir, 45 to receive 400 mg raltegravir, and 45 to receive 600 mg raltegravir; 45 patients were randomly assigned to receive placebo. One patient in the 200 mg group did not receive treatment and was therefore excluded from the analyses. For all groups, the median duration of previous antiretroviral therapy was 9.9 years (range 0.4-17.3 years) and the mean baseline viral load was 4.7 (SD 0.5) log10 copies per mL. Four patients discontinued due to adverse experiences, three (2%) of the 133 patients across all raltegravir groups and one (2%) of the 45 patients on placebo. 41 patients discontinued due to lack of efficacy: 14 (11%) of the 133 patients across all raltegravir groups and 27 (60%) of the 45 patients on placebo. At week 24, mean change in viral load from baseline was -1.80 (95% CI -2.10 to -1.50) log10 copies per mL in the 200 mg group, -1.87 (-2.16 to -1.58) log10 copies per mL in the 400 mg group, -1.84 (-2.10 to -1.58) log10 copies per mL in the 600 mg group, and -0.35 (-0.61 to -0.09) log(10) copies per mL for the placebo group. Raltegravir at all doses showed a safety profile much the same as placebo; there were no dose-related toxicities. INTERPRETATION: In patients with few remaining treatment options, raltegravir at all doses studied provided better viral suppression than placebo when added to an optimised background regimen. The safety profile of raltegravir is comparable with that of placebo at all doses studied.

Six-year follow-up of HIV-1-infected adults in a clinical trial of antiretroviral therapy with indinavir, zidovudine, and lamivudine.

OBJECTIVE: To assess virological and immunological responses and toxicity in subjects receiving combination antiretroviral therapy. DESIGN: Six-year follow-up of a single arm of a randomized study of combination antiretroviral therapy. METHODS: HIV-infected, zidovudine-experienced patients originally randomized to receive indinavir, zidovudine, and lamivudine had HIV RNA levels and CD4 cell counts assessed over 6 years. Information was collected by questionnaire from subjects who discontinued the study regimen before 6 years. Both on-study and post-study responses were assessed. RESULTS: Of 33 subjects, 16 (48%) discontinued before 6 years of follow-up. After 6 years, 16 (53%) and 14 (47%) of 30 contributing subjects had HIV RNA levels < 500 and < 50 copies/ml, respectively, and the median increase in CD4 cell count from baseline for 28 contributing subjects was 268 x 10(6) cells/l. Treatment-limiting nephrolithiasis occurred in four subjects. Of the 16 subjects who discontinued the study, 12 had post-study questionnaire data available and seven had HIV RNA < 500 copies/ml on a post-study regimen. In an exploratory analysis combining both on-study and post-study data at approximately 6 years, 26 (79%) and 19 (58%) of 33 had HIV RNA levels < 500 and < 50 copies/ml, respectively, and the median increase in CD4 cell count from baseline was 344 x 106 cells/l. CONCLUSIONS: Antiretroviral therapy with indinavir, zidovudine, and lamivudine suppressed HIV viremia and produced continued CD4 cell increases in a majority of subjects for 6 years. Most subjects who discontinued study medications had HIV RNA levels suppressed on post-study therapy. Though based on a small group, this study demonstrates the durable effects of antiretroviral therapy.

Evidence of immune reconstitution in antiretroviral drug-experienced patients with advanced HIV disease.

Highly active antiretroviral therapy (HAART) of HIV disease is associated with effective virologic control, immune reconstitution, and clinical improvements. This study addresses the potential for improvements in lymphocyte phenotype and virologic responses of HIV-infected persons with extensive experience with dual nucleoside reverse transcriptase (NRTI) treatment and advanced HIV disease after a change to a potent antiretroviral therapy (NRTI + protease inhibitor). The majority of participants achieved virologic success. There was a median rise in CD4+ lymphocytes of 99 cells/mm(3) by 48 weeks, because of an increase in memory CD4+ cells at 4 and 16 weeks, followed by a later increase in naive CD4+ cells between weeks 16 and 48. The proportion of activated, DR+ CD38+ CD8+ lymphocytes decreased during the 48 weeks of follow-up. The immunologic findings (increased memory and naive T cells and reduced activation levels) were significantly improved in participants with persistent suppression of viral replication over the 48 weeks of the study. Baseline HIV RNA copy number was lower (median, 14,784 copies/ml) in persons who responded virologically than in those not suppressing viral replication (median, 49,454 copies/ml). CD4+ cell counts above the median (125/mm(3)) at time 0 for the participants, was the only baseline immunologic marker significantly associated with viral suppression at week 48. Participants older than 40 years of age demonstrated less immunologic recovery. The results of the study show that patients with extensive experience with NRTIs respond both virologically and immunologically during the first 48 weeks of therapy with a potent antiretroviral regimen.

Long-term efficacy and safety of the HIV integrase inhibitor raltegravir in patients with limited treatment options in a Phase II study.

BACKGROUND: Raltegravir in combination therapy has demonstrated potent suppression of HIV-1 with a favorable safety profile. This report provides 96-week efficacy and safety data from Protocol 005, a Phase II study. METHODS: HIV-infected patients with very limited treatment options and failing antiretroviral therapy were randomized to raltegravir 200, 400, or 600 mg or placebo b.i.d., plus optimized background therapy for >or=24 weeks; all patients were then offered open-label raltegravir 400 mg b.i.d. Efficacy measurements included changes in viral load and CD4 count from baseline and percent of patients with HIV-1 RNA <400 and <50 copies/mL. RESULTS: One hundred and thirty-three patients received raltegravir and 45 received placebo. No dose-dependent differentiation in the safety or antiviral activity of raltegravir was observed during the double-blind phase. For the combined raltegravir groups, mean change in viral load from baseline was -1.60 log10 copies/mL at week 48 and -1.38 log10 copies/mL at week 96 (observed failure approach). At week 48, HIV-1 RNA levels were <400 copies/mL in 68% of raltegravir recipients and <50 copies/mL in 55%; these levels were maintained in 55% and 48% of raltegravir recipients, respectively, at week 96 (noncompleter = failure). There were few discontinuations of raltegravir (4%) due to adverse events. CONCLUSIONS: In patients with limited treatment options, raltegravir with OBT had a potent and sustained antiretroviral effect and was generally well tolerated through 96 weeks.
