Abstract

RationaleThe relationship between leukocyte gene expression and recovery of respiratory function after injury may provide information on the etiology of multiple organ dysfunction.ObjectivesTo find a list of genes for which expression after injury predicts respiratory recovery, and to identify which networks and pathways characterize these genes.MethodsBlood was sampled at 12 hours and at 1, 4, 7, 21 and 28 days from 147 patients who had been admitted to the hospital after blunt trauma. Leukocyte gene expression was measured using Affymetrix oligonucleotide arrays. A linear model, fit to each probe-set expression value, was used to impute the gene expression trajectory over the entire follow-up period. The proportional hazards model score test was used to calculate the statistical significance of each probe-set trajectory in predicting respiratory recovery. A list of genes was determined such that the expected proportion of false positive results was less than 10%. These genes were compared to the Gene Ontology for 'response to stimulus' and, using Ingenuity software, were mapped into networks and pathways.Measurements and main resultsThe median time to respiratory recovery was 6 days. There were 170 probe-sets representing 135 genes that were found to be related to respiratory recovery. These genes could be mapped to nine networks. Two known pathways that were activated were antigen processing and presentation and JAK-signaling.ConclusionsThe examination of the relationship of gene expression over time with a patient's clinical course can provide information which may be useful in determining the mechanism of recovery or lack of recovery after severe injury.

Abstract

Maraviroc treatment for HIV-1 infected patients results in larger CD4(+) T cell rises than are attributable to its antiviral activity alone. We investigated whether this is due to modulation of T cell activation and inflammation.Thirty maraviroc-treated patients from the Maraviroc versus Efavirenz Regimens as Initial Therapy (MERIT) study were randomly selected from among those who had CCR5-tropic (R5) HIV on screening and achieved undetectable HIV RNA (2 µg/mL increased from 45% to 66% in the efavirenz arm, but remained constant in the maraviroc arm (P = 0.033). Decreases in CD38 expression on CD8(+) T cells were correlated with CD4(+) T cell rises for maraviroc treatment (r = -0.4, P = 0.048), but not for treatment with efavirenz.Maraviroc-treated patients had earlier, modest decreases in certain markers of immune activation and inflammation, although in this small study, many of the differences were not statistically significant. Levels of high-sensitivity C-reactive protein remained constant in the maraviroc arm and increased in the efavirenz arm. Decreases in immune activation correlated with increased CD4(+) T cell gains.ClinicalTrials.gov NCT00098293.

Abstract

Background: Despite advances in surgery and pharmacotherapy, there remains significant residual ischemic risk after coronary artery bypass grafting surgery. Methods: In REDUCE-IT (Reduction of Cardiovascular Events With Icosapent Ethyl–Intervention Trial), a multicenter, placebo-controlled, double-blind trial, statin-treated patients with controlled low-density lipoprotein cholesterol and mild to moderate hypertriglyceridemia were randomized to 4 g daily of icosapent ethyl or placebo. They experienced a 25% reduction in risk of a primary efficacy end point (composite of cardiovascular death, myocardial infarction, stroke, coronary revascularization, or hospitalization for unstable angina) and a 26% reduction in risk of a key secondary efficacy end point (composite of cardiovascular death, myocardial infarction, or stroke) when compared with placebo. The current analysis reports on the subgroup of patients from the trial with a history of coronary artery bypass grafting. Results: Of the 8179 patients randomized in REDUCE-IT, a total of 1837 (22.5%) had a history of coronary artery bypass grafting, with 897 patients randomized to icosapent ethyl and 940 to placebo. Baseline characteristics were similar between treatment groups. Randomization to icosapent ethyl was associated with a significant reduction in the primary end point (hazard ratio [HR], 0.76 [95% CI, 0.63–0.92]; P =0.004), in the key secondary end point (HR, 0.69 [95% CI, 0.56–0.87]; P =0.001), and in total (first plus subsequent or recurrent) ischemic events (rate ratio, 0.64 [95% CI, 0.50–0.81]; P =0.0002) compared with placebo. This yielded an absolute risk reduction of 6.2% (95% CI, 2.3%–10.2%) in first events, with a number needed to treat of 16 (95% CI, 10–44) during a median follow-up time of 4.8 years. Safety findings were similar to the overall study: beyond an increased rate of atrial fibrillation/flutter requiring hospitalization for at least 24 hours (5.0% vs 3.1%; P =0.03) and a nonsignificant increase in bleeding, occurrences of adverse events were comparable between groups. Conclusions: In REDUCE-IT patients with a history of coronary artery bypass grafting, treatment with icosapent ethyl was associated with significant reductions in first and recurrent ischemic events.

Abstract

ACROSTUDY is an open-label, non-interventional post-authorization safety study (PASS) that began in 2004 to evaluate safety in at least 1000 acromegaly patients treated for 5 years with the GH receptor antagonist pegvisomant (PEGV). This commitment was fulfilled in 2013 but ACROSTUDY was extended as a voluntary PASS, ultimately collecting data on 2221 patients who were followed through Dec 2017. Objectives: To monitor the long-term safety of PEGV including the pituitary tumor volume, as prescribed in clinical practice. Patients & Methods: 50.8% were male, 92.4% Caucasian with median age 41.1 years (1.7-83.7) at diagnosis and median age 49.7 years (3.9-85.6) at start of PEGV. Mean duration of PEGV treatment was 9.3 years (0.0-20.8); 80.8% of patients started PEGV on a daily schedule and patients came from fifteen countries. Safety data included adverse events, change in tumor volume and liver tests. Efficacy was measured by IGF-I control (Patients were considered ‘IGF-I Controlled’ if the most temporally-related IGF-I measurement was normal for the local reference laboratory). Patient-reported outcomes (PROs) were evaluated using the PatientAssessed Acromegaly Symptom Questionnaire (PASQ). Results: No new safety signals were identified in the study. IGF-I SDS >2 decreased progressively from 88.4% of patients at baseline to 34.8% at year 5 at a mean dose(±SD) of 19.2(±12.9) mg/day; 63.3% of patients with a documented normal IGF-I SDS had a mean dose of 16.2(±9.03), while 1.9% had IGF-I SDS < -2 at a mean dose of 16.5(±5.81). 1795 Patients had at least 1 local pituitary imaging result reported: 71.1% of patients reported no change, 17.3% reported a decrease and 7.1% reported an increase in tumor size while 4.5% reported both an increase and a decrease. Scans reported as showing a meaningful change in tumor volume (n=264) were re-evaluated centrally by an independent expert: 54 were corroborated enlarged, 84 were decreased, 12 were read as both increased and decreased, 23 were read as no change and 40 inconclusive; thus the overall incidence of (corroborated) tumor increases was 3.0% and decreases 4.7%. In the overall cohort, AST and/or ALT were >3 × ULN at any time during PEGV treatment in 3.2% of patients. PASQ score was 15 (0-46) at baseline and 10 (0-41) at year 8. Summary: In this real world international study, overall biochemical control (i.e. normal IGF-I) progressively improved with pegvisomant, and was achieved in 63.3% patients by year 5. Improved IGF-I control was associated with improved symptoms of acromegaly. Importantly, in this large cohort of patients the incidence of pituitary tumor increase and liver test elevations were low, and similar to previously reported rates. One limitation of this observational study was that the PEGV dose may not have been adequately titrated to achieve IGF-I normalization.

Abstract

For clinical studies of chronic diseases, patients are followed to determine whether treatment results in either improvement or decline in their clinical status. During periodic exams, laboratory specimens are collected that are believed to reflect both the progression and improvement in the disease status. Often patients miss visits and return with a changed disease status, resulting in interval-censored laboratory markers and indicators of disease status. The goal of this paper is to propose a single test that would evaluate the relationship between a longitudinal marker and clinical progression or recovery when missing visits result in interval-censored covariate and outcome data. We apply our test to evaluate the relationship between treatment compliance and progression and remission of renal disease in diabetic patients.

Abstract

OBJECTIVES: To determine factors associated with CD4 responses to maraviroc (MVC)-containing regimens in treatment-experienced patients. METHODS: Forty-eight-week data from MOTIVATE 1 and 2 was used to assess MVC once or twice daily versus placebo (PBO), each with optimized background therapy (N = 1047). A repeated measures model evaluated longitudinal CD4 changes, multivariate linear regression evaluated predictors of week 48 increases, and Cox proportional hazard modeling evaluated time to category C events. RESULTS: Median CD4 increases were greater on MVC once or twice daily than PBO (92, 103, and 24 cells/mm3, respectively; P < 0.05), and the difference remained significant among patients achieving less than 50 HIV-1 RNA copies/mL (126, 125, and 96 cells/mm3; P < 0.05) or when adjusted for other predictors of CD4 increase including change in HIV-1 RNA. Time to a category C event was longer on MVC; in multivariate models, higher on-treatment CD4 count, but not MVC treatment, was protective against new events (hazard ratio 0.8 per +25 cells/mm3; 95% confidence interval 0.78-0.87). CONCLUSIONS: MOTIVATE patients receiving MVC had larger CD4+ T-cell increases than those receiving PBO, even after adjusting for the greater virologic potency of MVC-containing regimens. This additional CD4 response was associated with a longer time to the development of AIDS-defining events on MVC.

Abstract

The NIH project 'Inflammatory and Host Response to Injury' (Glue) is being conducted to study the changes in the body over time in response to trauma and burn. Patients are monitored for changes in their clinical status, such as the onset of and recovery from organ failure. Blood samples are drawn over the first days and weeks after the injury to obtain gene expression levels over time. Our goal was to develop a method of selecting genes that differentially expressed in patients who either improved or experienced organ failure. For this, we needed a test for the association between longitudinal gene expressions and the time to the occurrence of ordered categorical outcomes indicating recovery, stable disease, and organ failure. We propose a test for which the relationship between the gene expression and the events is modeled using the cumulative proportional odds model that is a generalization of the pooling repeated observation method. Given the high-dimensionality of the microarray data, it was necessary to control for the multiplicity of the testing. To control for the false discovery rate (FDR), we applied both a permutational approach as well as Efron's empirical estimation method. We explore our method through simulations and provide the analysis of the multi-center, longitudinal study of immune response to inflammation and trauma (http://www.gluegrant.org).

Abstract

Biostatistics is not universally available in colleges/universities and is thus an attractive course to offer via distance education. However, evaluation of the impact of distance education on course enrollment and student success is lacking. We evaluated an “Introduction to Biostatistics” course at Harvard University that offered the distance option (Spring 2005).We assessed the effect on course enrollment and compared the grades of traditional students with non-traditional students, as well as with historical traditional students (Fall 2004). We further compared course evaluations from the inaugural semester with the distance option to evaluations from the prior semester. No evidence of dissimilarities was noted with respect to overall course grade averages or course evaluations. First published November 2007 at Statistics Education Research Journal: Archives

Abstract

Prevalence of hepatitis B virus (HBV) markers, including occult HBV, has not been described in diverse cohorts among HIV-infected patients. The objective of this study was to assess prevalence and significance of active and occult HBV infection in an HIV-positive US cohort. A random sample was taken from 2 prospective multicenter treatment intervention cohorts. The sample population (n = 240) was HIV-1 infected and highly active antiretroviral therapy-naive. Prevalence of HBV serologic markers and quantitative HBV DNA were determined. Serum alanine aminotransferase (ALT) levels were measured to evaluate correlates of hepatocyte injury. A total of 64.6% of subjects demonstrated reactivity for any marker of current or past HBV infection or prior vaccination. Chronic HBV infection characterized by hepatitis B surface antigen (HBsAg) reactivity was present in 7.1% while 15.8% exhibited HB anticore IgG only. Approximately 10% of the latter group was HBV DNA positive by a polymerase chain reaction-based assay. Only patients with a serologic pattern of HBsAg or HB anticore alone reactivity had HBV DNA. Occult HBV was observed in approximately 10% of HIV-infected patients with HB anticore IgG antibody in a geographically representative national cohort. Though viral titers and serum ALT levels were low, screening of this subset of HIV-infected patients may have implications in terms of antiretroviral therapy and risk of immune reconstitution-associated flares.

Abstract

In this international, noncomparative, randomized phase II trial, we evaluated the effectiveness and tolerance of atovaquone suspension (1500 mg orally twice daily) plus either pyrimethamine (75 mg per day after a 200-mg loading dose) or sulfadiazine (1500 mg 4 times daily) as treatment for acute disease (for 6 weeks) and as maintenance therapy (for 42 weeks) for toxoplasmic encephalitis (TE) in patients infected with human immunodeficiency virus. Twenty-one (75%) of 28 patients receiving pyrimethamine (95% lower confidence interval [CI], 58%) and 9 (82%) of 11 patients receiving sulfadiazine (95% lower CI, 53%) responded to treatment for acute disease. Of 20 patients in the maintenance phase, only 1 experienced relapse. Eleven (28%) of 40 eligible patients discontinued treatment as a result of adverse events, 9 because of nausea and vomiting or intolerance of the taste of the atovaquone suspension. Although gastrointestinal side effects were frequent, atovaquone-containing regimens are otherwise well tolerated and safe and may be useful for patients intolerant of standard regimens for toxoplasmic encephalitis.

Abstract

Background/Aims: Growth hormone (GH) treatment regimens for children with non-GH-deficient, idiopathic short stature (ISS) have not been optimized. To compare the efficacy, efficiency, and safety of an individualized, target-driven GH regimen with standard weight-based dosing after 4 years of treatment. Methods: This is a 4-year, open-label, multicenter, randomized trial comparing individualized, formula-based dosing of Genotropin® versus a widely used ISS dose of Genotropin®. Subjects were prepubertal, had a bone age of 3-10 years for males and 3-9 years for females, were naive to GH treatment, and had a height standard deviation score (Ht SDS) of -3 to -2.25, a height velocity 10 ng/ml. After the first 2 years, the individualized-dosing group was further randomized to either 0.18 or 0.24 mg/kg/week. Results: At 4 years, subjects in all treatment regimens achieved similar average height gains of +1.3 SDS; however, the individualized dosing regimen utilized less GH to achieve an equivalent height gain. Conclusion: Individualized, formula-based GH dosing, followed by a dose reduction after 2 years, provides a more cost-effective growth improvement in patients with ISS than currently employed weight-based regimens.

Abstract

OBJECTIVE To determine the efficacy and safety of amphotericin B oral suspension (ABOS) for the treatment of fluconazole refractory oral candidiasis in persons with HIV infection. DESIGN AND SETTING A prospective, multicenter, open label trial at 25 study centers within the AIDS Clinical Trials Group. PATIENTS AND METHODS Individuals with diffuse oral candidiasis after 14 days of treatment with 200 mg of fluconazole daily (more than five plaques or a single plaque > 3 cm largest length) were treated with ABOS, 100 mg/ml, 5 ml swish and swallow, four times daily for 14 days. Thereafter incomplete or non-responders received an additional 14 days of therapy and responders received maintenance ABOS twice daily for up to 6 months. Relapses during maintenance ABOS were treated by increasing the dose to four times daily. MAIN OUTCOME MEASURES To demonstrate an ABOS clinical response rate > 33% and a treatment-limiting toxicity rate < 50%. Clinical response was defined as the absence of mouth pain and the presence of less than five oral plaques, the largest being < 3 cm largest dimension. RESULTS Fifty-eight subjects with a median age of 39 years and a median CD4 count of 10 x 10(6) cells/l were enrolled. Four subjects were excluded from the analysis because of inadequate follow-up after randomization (n = 3) or the presence of active esophageal disease (n = 1). Of the remaining 54 subjects, 23 (42.6%; 95% lower confidence interval, 31.1%) were classified as responders after 28 days. Five subjects (9%) stopped treatment due to toxicity. Relapse occurred in 16 responders (70%). CONCLUSIONS Amphotericin B oral suspension is well tolerated but has limited efficacy for the treatment of fluconazole refractory oral candidiasis.

Abstract

We describe a value-driven approach to optimizing pharmaceutical portfolios. Our approach incorporates inputs from research and development and commercial functions by simultaneously addressing internal and external factors. This approach differentiates itself from current practices in that it recognizes the impact of study design parameters, sample size in particular, on the portfolio value. We develop an integer programming (IP) model as the basis for Bayesian decision analysis to optimize phase 3 development portfolios using expected net present value as the criterion. We show how this framework can be used to determine optimal sample sizes and trial schedules to maximize the value of a portfolio under budget constraints. We then illustrate the remarkable flexibility of the IP model to answer a variety of 'what-if' questions that reflect situations that arise in practice. We extend the IP model to a stochastic IP model to incorporate uncertainty in the availability of drugs from earlier development phases for phase 3 development in the future. We show how to use stochastic IP to re-optimize the portfolio development strategy over time as new information accumulates and budget changes occur.

Abstract

"We investigated the effects of maraviroc, the first approved CC-chemokine receptor 5 (CCR5) antagonist, on blood lipids in a post hoc analysis of the phase 3 MERIT study in treatment-naive patients. Methods: Patients received maraviroc 300 mg twice daily (n = 360) or efavirenz 600 mg once daily (n = 361), both in combination with zidovudine\/lamivudine, for up to 96 weeks. Baseline and on-treatment lipid profiles were analyzed according to National Cholesterol Education Program (NCEP) thresholds. Results: Baseline characteristics and lipid profiles were comparable between groups. Among patients with total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-c) below NCEP treatment thresholds at baseline, significantly more efavirenz- than maraviroc-treated patients exceeded those thresholds at 96 weeks (TC: 35% [74\/209] vs 11% [20\/188], P < .0001; LDL-c: 23% [47\/197] vs 8% [15\/183], P < .0001). Among patients exceeding NCEP thresholds at baseline, significantly more efavirenz- than maraviroc-treated patients exceeded the thresholds at 96 weeks (TC: 83% [24\/29] vs 50% [17\/34], P = .0084; LDL-c: 86% [19\/22] vs 55% [16\/29], P = .0314).

Abstract

Background: Improved ease of use of drug-delivery devices may enhance compliance. Development of an easier-to-use device for administration of recombinant human growth hormone (rhGH) may thus be beneficial for patients and their caregivers. Objective: This study compared ease of use and preference for a new disposable rhGH injection pen relative to previous experience with the currently available reusable pen in standard practice. Both pens deliver the same formulation of rhGH. Methods: This multicenter, single-arm, open-label study assessed ease of use and preference for the 2 injection pens in patient-caregiver dyads. Eligible children were aged 8 through 18 years, were currently being treated with rhGH, and had been compliant with use of the current reusable pen for ≥3 months before study entry. A validated self-reported Injection Pen Assessment Questionnaire was administered twice during the study—at baseline (to assess perceptions of the reusable pen) and after 2 months of use of the new disposable pen—to assess ease of use of the individual pens (rated on a 5-point Likert-type scale), the comparative ease of use of the 2 pens, and pen preference. The primary end point was the proportion of dyads who rated the new pen as no different or easier to use than the current pen. Regardless of treatment or suspected causal relationship to the investigational product, all observed or volun- teered adverse events (AEs) were recorded and rated as mild, moderate, or severe. Results: Of 137 screened dyads, 136 (91 boys, 45 girls) were included in the safety population and 133 were included in the efficacy population. The children had a mean age of 12.3 years, a mean weight of 42.2 kg, a mean height of 145.9 cm, and a mean body mass index of 19.3 kg/m 2 ; 84.6% of the children were white. The majority (82.4%) of adult dyad members were subjects' mothers. The adult dyad members were more likely than the child members to be responsible for preparing the injection (82.0%) and administering the injection (72.9%). Overall, 73.7% of dyads rated the new disposable pen no different or easier to use than the reusable pen (95% CI, 66.2%–81.2%), and 65.2% rated the disposable pen no different or preferable to the reusable pen (95% CI, 57.0%–73.3%). Overall, 60 all-causality AEs occurred in 28 subjects (20.6%), most of them (93.3%) either mild or moderate in intensity. Eight device-related AEs occurred in 7 subjects (5.1%) (injection-site hematoma in 3 and injection-site pain in 5). The most common AEs were headache (7 events), injection-site pain (5), upper respiratory tract infection (4), and pyrexia (4). No deaths or serious AEs were reported. Conclusions: Nearly three quarters of patients and caregivers reported that the new disposable pen was no Accepted for publication October 1, 2010. different or easier to use than the reusable pen, and nearly two thirds preferred the disposable pen. No safety concerns were identified. The findings suggest that the improvements in the new pen were recognized by patients and caregivers.

Abstract

The NIH project ”Inflammatory and Host Response to Injury” (Glue) is being conducted to study the changes in the body over time in response to trauma and burn. Patients are monitored for changes in their clinical status, such as the onset of and recovery from organ failure. Blood samples are drawn over the first days and weeks after the injury to obtain gene expression levels over time. Our goal was to develop a method of selecting genes that differentially expressed in patients who either improved or experienced organ failure. For this, we needed a test for the association between longitudinal gene expressions and the time to the occurrence of ordered categorical outcomes indicating recovery, stable disease, and organ failure. We propose a test for which the relationship between the gene expression and the events is modeled using the cumulative proportional odds model that is a generalization of the Pooling Repeated Observation (PRO) method. Given the high-dimensionality of the microarray data, it was necessary to control for the multiplicity of the testing. To control for the false discovery rate (FDR), we applied both a permutational approach as well as Efron's empirical estimation methods. We explore our method through simulations and provide the analysis of the multi-center, longitudinal study of immune response to inflammation and trauma (http://www.gluegrant.org).

Abstract

BACKGROUND: Normalization of IGF-I in patients with acromegaly is associated with a decrease in mortality. Pegvisomant may be more effective in lowering IGF-I than octreotide. SUBJECTS AND METHODS: The efficacy and safety of pegvisomant and octreotide long-acting release (LAR) were compared in 118 patients with acromegaly in this 52-week, multicenter, open-label, randomized study. The primary endpoint was IGF-I normalization at week 52. Secondary endpoints included mean changes from baseline in IGF-I, IGF binding protein 3, acromegaly signs and symptom scores, ring size, acromegaly quality of life questionnaire scores, and safety. RESULTS: Fifty-six patients received pegvisomant and 57 received octreotide LAR. IGF-I normalized in 51% of pegvisomant patients and 34% treated with octreotide LAR (p=0.09, ns). Patients with baseline IGF-I > or = 2x upper limit of normal had a higher rate of IGF-I normalization with pegvisomant vs octreotide LAR (p=0.05). Among the patients who did not achieve a normalized IGF-I, pegvisomant-treated patients were more likely to be receiving < 30 mg of study drug (71% vs 16%). Treatment-related adverse events were mild-to-moderate in both groups. Mean fasting glucose decreased in diabetic and non-diabetic patients on pegvisomant whereas octreotide LAR was associated with an increase at week 52 (p=0.005 and p=0.003 between groups, respectively). Mean change in tumor volume during treatment was similar between groups. CONCLUSIONS: Pegvisomant and octreotide LAR were equally effective in normalizing IGF-I in the overall population, and pegvisomant was more effective in patients with higher baseline IGF-I levels. Pegvisomant had a more favorable effect on parameters of glycemic control.

Abstract

Motivation: The development of methods for linking gene expressions to various clinical and phenotypic characteristics is an active area of genomic research. Scientists hope that such analysis may, for example, describe relationships between gene function and clinical events such as death or recovery. Methods are available for relating gene expression to measurements that are categorized or continuous, but there is less work in relating expressions to an observed event time such as time to death, response or relapse. When gene expressions are measured over time, there are methods for differentiating temporal patterns. However, methods have not yet been proposed for the survival analysis of longitudinally collected microarrays. Results: We describe an approach for the survival analysis of longitudinal gene expression data. We construct a measure of association between the time to an event and gene expressions collected over time. Statistical significance is addressed using permutations and control of the false discovery rate. Our proposed method is illustrated on a dataset from a multi-center research study of inflammation and response to injury that aims to uncover the biological reasons why patients can have dramatically different outcomes after suffering a traumatic injury ().

Abstract

Although activation of human innate immunity after endotoxin administration is well established, in vivo endotoxin effects on human T cell responses are not well understood. Most naive human T cells do not express receptors for LPS, but can respond to endotoxin-induced mediators such as chemokines. In this study, we characterized the in vivo response of peripheral human T cell subsets to endotoxin infusion by assessing alterations in isolated T cells expressing different phenotypes, intracellular cytokines, and systemic chemokines concentration, which may influence these indirect T cell responses. Endotoxin administration to healthy subjects produced T cell activation as confirmed by a 20% increase in intracellular IL-2, as well as increased CD28 and IL-2R α-chain (CD25) expression. Endotoxin induced indirect activation of T cells was highly selective among the T cell subpopulations. Increased IL-2 production (36.0 ± 3.7 to 53.2 ± 4.1) vs decreased IFN-γ production (33.8 ± 4.2 to 19.1 ± 3.2) indicated selective Th1 activation. Th2 produced IL-13 was minimally increased. Differentially altered chemokine receptor expression also indicated selective T cell subset activation and migration. CXCR3+ and CCR5+ expressing Th1 cells were decreased (CXCR3 44.6 ± 3.2 to 33.3 ± 4.6 and CCR5 24.8 ± 2.3 to 12 ± 1.4), whereas plasma levels of their chemokine ligands IFN-γ-inducible protein 10 and MIP-1α were increased (61.4 ± 13.9 to 1103.7 ± 274.5 and 22.8 ± 6.2 to 55.7 ± 9.5, respectively). In contrast, CCR4+ and CCR3 (Th2) proportions increased or remained unchanged whereas their ligands, eotaxin and the thymus and activation-regulated chemokine TARC, were unchanged. The data indicate selective activation among Th1 subpopulations, as well as differential Th1/Th2 activation, which is consistent with a selective induction of Th1 and Th2 chemokine ligands.

Abstract

Objective To assess the safety, tolerability and effect of cidofovir for HIV-1 associated progressive multifocal leukoencephalopathy. Design Prospective, open-label study in nine AIDS Clinical Trials Units. Patients and methods Twenty-four HIV-1-infected individuals, with neuroimaging and clinical findings consistent with PML, and symptoms for 90 days or less, whose diagnosis was confirmed by the detection of JC virus DNA in the cerebrospinal fluid or brain biopsy, received cidofovir 5 mg/kg intravenously at baseline and 1 week, followed by infusions every 2 weeks with the dose adjusted for renal function. Follow-up continued to 24 weeks. The safety of cidofovir and changes in neurological examination scores between baseline and week 8 were assessed. Results Seventeen subjects were receiving potent antiretroviral agents. Survival at 12 weeks was 54%. The CD4 cell count at entry was significantly associated with survival (P = 0.02). Five subjects discontinued treatment because of toxicity: a 50% or greater decrease in intraocular pressure in either eye in four, and proteinuria in one. Overall, magnetic resonance imaging abnormalities and neurological examination scores worsened. Only two subjects experienced a 25% or greater improvement in neurological examination scores at week 8, which were significantly better in subjects with HIV-1-RNA levels of 500 copies/ml or less at entry compared with those with HIV-1-RNA levels over 500 copies/ml (P = 0.05). Conclusion Cidofovir did not improve neurological examination scores at week 8. However, such scores were significantly better in subjects who entered with suppressed plasma HIV-1-RNA levels, which could be the result of control of HIV-1 infection itself or cidofovir.

Abstract

In this international, noncomparative, randomized phase II trial, we evaluated the effectiveness and tolerance of atovaquone suspension (1500 mg orally twice daily) plus either pyrimethamine (75 mg per day after a 200-mg loading dose) or sulfadiazine (1500 mg 4 times daily) as treatment for acute disease (for 6 weeks) and as maintenance therapy (for 42 weeks) for toxoplasmic encephalitis (TE) in patients infected with human immunodeficiency virus. Twenty-one (75%) of 28 patients receiving pyrimethamine (95% lower confidence interval [CI], 58%) and 9 (82%) of 11 patients receiving sulfadiazine (95% lower CI, 53%) responded to treatment for acute disease. Of 20 patients in the maintenance phase, only 1 experienced relapse. Eleven (28%) of 40 eligible patients discontinued treatment as a result of adverse events, 9 because of nausea and vomiting or intolerance of the taste of the atovaquone suspension. Although gastrointestinal side effects were frequent, atovaquone-containing regimens are otherwise well tolerated and safe and may be useful for patients intolerant of standard regimens for toxoplasmic encephalitis.

Abstract

Hepatitis C virus (HCV) has emerged as an important etiologic agent of liver injury and failure in patients infected with human immunodeficiency virus (HIV). The prevalence and characteristics of HCV in a representative cohort of HIV-infected patients have not been described. Therefore, a representative sample of 1687 HIV-infected patients was studied; a 213-sample subcohort was selected by use of risk-based sampling from 2 large prospective US Adult AIDS Clinical Trials Group clinical trials. HCV prevalence, HCV RNA level, and genotype were determined. The weighted overall estimate of HCV prevalence in the study cohort was 16.1% (95% weighted confidence interval, 14.3%-17.8%), with significant variability depending on risk factors and HIV RNA levels. Among patients defined as being "at risk", 72.7% were HCV positive, whereas, among low-risk patients, the positivity rate was 3.5%. Genotype 1 was found in 83.3% of infected patients. Median HCV RNA level was 6.08x106 IU/mL. High virus loads and genotype 1 prevalence may be important to interferon-based antiviral response rates among coinfected patients.

Abstract

Background: Maraviroc treatment for HIV-1 infected patients results in larger CD4 + T cell rises than are attributable to its antiviral activity alone. We investigated whether this is due to modulation of T cell activation and inflammation. Methods and Findings: Thirty maraviroc-treated patients from the Maraviroc versus Efavirenz Regimens as Initial Therapy (MERIT) study were randomly selected from among those who had CCR5-tropic (R5) HIV on screening and achieved undetectable HIV RNA (,50 copies/mL) by Week 48. Efavirenz-treated controls were matched for baseline characteristics to the maraviroc-treated patients selected for this substudy. Changes in immune activation and inflammation markers were examined for associations with CD4 + T cell changes. Maraviroc treatment tended to result in more rapid decreases in CD38 expression on CD4 + T cells and in plasma D-dimer concentrations than did treatment with efavirenz. The proportion of patients with high-sensitivity C-reactive protein .2 mg/mL increased from 45% to 66% in the efavirenz arm, but remained constant in the maraviroc arm (P=0.033). Decreases in CD38 expression on CD8 + T cells were correlated with CD4 + T cell rises for maraviroc treatment (r= 20.4, P=0.048), but not for treatment with efavirenz. Conclusions: Maraviroc-treated patients had earlier, modest decreases in certain markers of immune activation and inflammation, although in this small study, many of the differences were not statistically significant. Levels of highsensitivity C-reactive protein remained constant in the maraviroc arm and increased in the efavirenz arm. Decreases in immune activation correlated with increased CD4 + T cell gains. Trial Registration: ClinicalTrials.gov NCT00098293

Abstract

Background Certain infections occur more frequently in HIV-infected patients some of which are classified as AIDS-defining events. Theoretical concerns have been raised that CCR5 antagonists may have an adverse effect on the immune system. A 4-week immunotoxicology study in cynomolgous monkeys did not demonstrate any adverse effects of MVC on the immune system. MOTIVATE 1 and MOTIVATE 2 are randomized, double-blind, placebo (PBO)-controlled, Phase III studies assessing the safety and efficacy of MVC in TE patients with CCR5-tropic HIV1. In both studies, MVC+OBT demonstrated significantly greater virologic and immunologic efficacy and a similar safety profile compared with PBO+OBT at 48 weeks.
