Safety and Effectiveness From the Cabotegravir and Rilpivirine Implementation Study in European Locations Study: Phase 3b Hybrid Type III Implementation Study Integrating Cabotegravir + Rilpivirine Long-Acting Into European Clinical Settings.

BACKGROUND: Cabotegravir + rilpivirine long-acting (CAB + RPV LA) dosed every 2 months (Q2M) is a complete regimen for the maintenance of HIV-1 virologic suppression. In this study, we report month 12 clinical outcomes in patient study participants (PSPs) in the CAB and RPV Implementation Study in European Locations (CARISEL) study. SETTING: CARISEL is a phase 3b implementation-effectiveness study. METHODS: CARISEL was designed as a 2-arm, unblinded study with centers randomized to either enhanced or standard implementation arms. For PSPs, this study is single arm, unblinded, and interventional; all PSPs switched from daily oral therapy to CAB + RPV LA dosed Q2M. The primary objective was to evaluate the perceived acceptability, appropriateness, and feasibility of CAB + RPV LA implementation for staff participants (presented separately). Clinical secondary endpoints assessed through month 12 included the proportion of PSPs with plasma HIV-1 RNA ≥50 and <50 copies/mL (Snapshot algorithm), incidence of confirmed virologic failure (CVF; 2 consecutive plasma HIV-1 RNA levels ≥200 copies/mL), adherence to injection visit windows, and safety and tolerability. RESULTS: Four hundred thirty PSPs were enrolled and treated; the mean age was 44 years (30% ≥50 years), 25% were women (sex at birth), and 22% were persons of color. At month 12, 87% (n = 373/430) of PSPs maintained HIV-1 RNA <50 copies/mL, with 0.7% (n = 3/430) having HIV-1 RNA ≥50 copies/mL. One PSP had CVF. The safety profile was consistent with previous findings. Overall, the results were similar between implementation arms. CONCLUSION: CAB + RPV LA Q2M was well tolerated and highly effective in maintaining virologic suppression with a low rate of virologic failure.

Low cabotegravir trough concentrations without oral lead-in in patients with HIV-1 switching to long-acting cabotegravir and rilpivirine.

In a cohort of 72 consecutive virologically-suppressed patients with HIV-1 switching to long-acting cabotegravir and rilpivirine, we observed low cabotegravir trough concentrations 1 and 3 months after the first injection, with a significant association with no oral lead-in at 1 month [odds ratio (OR) = 6.3 [95% confidence interval (CI) 1.7-29.5], P = 0.01] and three months (OR = 5.6 [95% CI 1.3-29.7], P = 0.03), and with high BMI at 1 month (OR = 1.3 [95% CI 1.1-1.6], P = 0.007).

Nonorgan-specific autoantibodies in HIV-infected patients in the HAART era.

Nonorgan-specific autoantibodies (AAbs) are used for diagnosing autoimmune diseases but can also be detected in other conditions. We carried out a cross-sectional study with the aim to screen HIV1-infected patients in the era of highly active antiretroviral therapy (HAART) for AAbs and to analyze the association of their presence with hypergammaglobulinemia and immunovirological status.Blood samples from HIV1-infected patients without major concomitant illnesses followed in 2 hospitals in Paris, France were tested for immunovirological status, serum immunoglobulin G (IgG) level, antinuclear antibodies (ANAs), anti-double-stranded DNA (anti-dsDNA), anti-extractable nuclear antigens (anti-ENAs), anticardiolipin (aCL), anti-ß2glycoprotein1 (anti-ß2GP1), and antineutrophil cytoplasmic antibodies (ANCAs). Clinically relevant AAbs were defined as ANAs with titers ≥1:160, anti-dsDNA or anti-ENA antibodies; aCL or anti-ß2GP1 antibodies with a level ≥40 U/ml; and ANCAs reacting with proteinase 3 or myeloperoxidase.We included 92 patients (mean age 47 years, men 55%, sub-Saharan African background 55%, HAART 85%, mean CD4 lymphocyte count 611/mm, viral load < 40 copies/mL 74%). At least 1 AAb was detected in 45% of patients, mostly ANAs (33%) and ANCAs (13%); 12% had ≥1 clinically relevant AAb. Above-normal IgG levels were found in 71% of patients. We found an inverse association between the presence of ≥1 AAb and CD4 lymphocyte count (P = 0.03) and between above-normal IgG levels and duration of virological control (P = 0.02) and non-sub-Saharan African background (P = 0.001).In sum, in HIV1-infected patients without any major concomitant illness in the HAART era, the prevalence of AAbs remains high but AAb patterns leading to high suspicion of autoimmune diseases are rather uncommon. AAb presence is associated with reduced CD4 lymphocyte count but not hypergammaglobulinemia.

Tenofovir DF/emtricitabine and efavirenz combination therapy for HIV infection in patients treated for tuberculosis: the ANRS 129 BKVIR trial.

BACKGROUND: HIV-infected patients with TB need simplified, effective and well-tolerated antiretroviral regimens. METHODS: The French ANRS 129 BKVIR open trial evaluated the once-daily tenofovir DF/emtricitabine and efavirenz combination, started within 12 weeks after TB treatment initiation, in antiretroviral-naive HIV-1-infected patients. Success was defined as an HIV-1 RNA <50 copies/mL and TB cure at 48 weeks. RESULTS: TB was confirmed microbiologically (90%) or histologically (10%) in 69 patients (71% male; median age 43 years; 54% born in Africa). The median time between TB treatment initiation and antiretroviral therapy was 8 weeks (range 1-22 weeks). At baseline, median HIV-1 RNA was 5.4 log10 copies/mL and median CD4 cell count 74 cells/mm(3). In the ITT analysis, combined success at week 48 was achieved in 57/69 patients (83%, 95% CI 74-92). Twelve patients did not achieve virological success, and TB was not cured in one of them. Among the 47 patients who fully adhered to the strategy, the success rate was 96% (95% CI 90-100) and was not affected by low rifampicin and isoniazid serum concentrations. Forty-nine serious adverse events were reported in 31 patients (45%), and 11 led to antiretroviral drug interruption. All adverse events resolved. The immune reconstitution inflammatory syndrome occurred in 23 patients (33%, 95% CI 22-44), and was associated with a low baseline BMI (P = 0.03) and a low haemoglobin level (P = 0.02). CONCLUSION: These results support the use of tenofovir DF/emtricitabine and efavirenz combination therapy for HIV infection in patients with TB.

High Soluble CD14 Levels at Primary HIV-1 Infection Predict More Rapid Disease Progression.

The soluble CD14 (sCD14) level was found associated with mortality during the chronic phase of human immunodeficiency virus (HIV) infection. Here we assessed its prognostic value in 138 patients with primary HIV infection. Higher sCD14 levels were associated with death, from myocardial infarction, but this was based on 3 deaths only. Among 68 untreated patients, those with higher sCD14 levels had more rapid spontaneous CD4 cell decline during the first 18 months following primary infection. This association persisted after adjustment for age, the CD4 cell count, and HIV viral load at diagnosis.

HIV-1 DNA levels in peripheral blood mononuclear cells and cannabis use are associated with intermittent HIV shedding in semen of men who have sex with men on successful antiretroviral regimens.

BACKGROUND: Few data exist on the efficacy of combined antiretroviral therapy (cART) in semen of human immunodeficiency virus type 1 (HIV-1) infected men who have sex with men (MSM) with sustained control of HIV replication in blood. METHODS: HIV-1 infected MSM on successful cART for >6 months were enrolled. HIV-RNA was quantified in seminal plasma (spVL) and in blood plasma (bpVL) from 2 paired samples collected 4 weeks apart. Relationship between spVL and bpVL (measured by an ultrasensitive assay, LOQ 10 copies/mL), total peripheral blood mononuclear cells (PBMC)-associated HIV-DNA, sexually transmitted infections (STIs), and self-reported socio-behavioral characteristics was assessed using GEE logistic regression. RESULTS: In total, 157 patients were included. Median time with bpVL <50 copies/mL was 3.3 years. spVL was detectable in 23/304 samples (prevalence 7.6%). Median spVL was 145 cp/mL (100-1475). spVL was detectable on the first, on the second, and on both samples in 5, 14, and 2 men, respectively. In sum, 33 individuals (21%) had STIs (asymptomatic in 24/33). Residual bpVL was undetectable by ultrasensitive assay in 225/300 samples (75%). After multivariable adjustments, PBMC-associated HIV-DNA (OR 2.6[1.2; 6.0], for HIV-DNA > 2.5 log10 cp/10(6) PBMC, P = .02), and cannabis use during sexual intercourse (OR 2.8[1.2; 6.7], P = .02) were the only factors associated significantly with spVL. CONCLUSION: We show that HIV-RNA can be detected intermittently in semen of HIV-1 infected MSM despite successful cART. The size of blood HIV-1 reservoir predicted spVL detection. Our results indicated also that the possible effect of cannabis should be taken into account when developing prevention interventions targeted toward HIV-infected MSM on successful cART.

Long-term immunogenicity of two doses of 2009 A/H1N1v vaccine with and without AS03(A) adjuvant in HIV-1-infected adults.

OBJECTIVE: In immunocompromised patients, alternative schedules more immunogenic than the standard influenza vaccine regimen are necessary to enhance and prolong vaccine efficacy. We previously reported that the AS03A-adjuvanted 2009 A/H1N1v vaccine yielded a higher short-term immune response than the nonadjuvanted one in HIV-1-infected adults. This study reports the long-term persistence of the immune response. DESIGN AND METHODS: In a prospective, multicenter, randomized, patient-blinded trial, two doses of AS03A-adjuvanted H1N1v vaccine containing 3.75 µg haemagglutinin (n = 155; group A) or nonadjuvanted H1N1v vaccine containing 15 µg haemagglutinin (n = 151; group B), were administered 21 days apart. Haemagglutination inhibition and neutralizing antibodies were assessed 6 and 12 months after vaccination. RESULTS: In group A and B, the seroprotection rates were 83.7 and 59.4% at month 6, and 70.4 and 49.3 at month 12, respectively. In a multivariate analysis, persistence of seroprotection 12 months after vaccination was negatively associated with current smoking (odds ratio = 0.6, P = 0.03) and positively related with the AS03A-adjuvanted H1N1v vaccine (odds ratio = 2.7, P = 0.0002). CONCLUSION: In HIV-1-infected adults, two doses of adjuvanted influenza vaccine induce long-term persistence of immune response up to 1 year after vaccination.

Long-term efficacy and safety of raltegravir, etravirine, and darunavir/ritonavir in treatment-experienced patients: week 96 results from the ANRS 139 TRIO trial.

Among 103 patients with multidrug-resistant HIV who initiated raltegravir, etravirine, and darunavir/ritonavir-containing regimen in the ANRS 139 TRIO trial, 100 participated in extended follow-up and continued study treatment until week 96. Among them, 87 (87%) received an optimized background therapy including either nucleoside reverse transcriptase inhibitors or enfuvirtide, they were 78 (78%) at week 96. At week 96, 88% achieved durable virologic response (<50 copies/mL). CD4 response was maintained (median change of +150 cells/mm(3)). No major toxicity was reported. This triple drug combination showed sustained efficacy and thus should be strongly considered for patients with multiclass-resistant virus.

[Venous thromboembolism risk and prophylaxis in the acute hospital care setting (ENDORSE study): results obtained in France]. / Risque thromboembolique veineux et pratique de prévention hospitalière : résultats obtenus en France de l'étude internationale ENDORSE.

AIM: Information about the variation in the risk for venous thromboembolism (VTE) and in prophylaxis practices in France and around the world is scarce. METHODS: The Epidemiologic International Day for the Evaluation of Patients at Risk for Venous Thromboembolism in the Acute Hospital Care Setting (ENDORSE) study is a multinational cross-sectional survey designed to assess the prevalence of VTE risk in the acute hospital care setting, and to determine the proportion of at-risk patients who receive effective prophylaxis, in accordance with the 2004 American College of Chest Physicians (ACCP) guidelines. This paper gives the results of the ENDORSE study in the French centres in comparison with the global worldwide results of the ENDORSE study and with other Western Europe countries. RESULTS: In France, 18 randomized hospitals participated to the study between august 2006 and January 2007. 2844 patients were evaluated (917 from chirurgical wards and 1927 from medical wards). One thousand four hundred and nineteen patients (49.9%) were at VTE risk (78.3% in chirurgical wards and 36.4% in medical wards). Of the 1419 patients at VTE risk, 62.4% received ACCP-recommended VTE prophylaxis (71.2% in chirurgical wards and 53.5% in medical wards). VTE Prophylaxis in France (62.4%) is more frequent than worldwide in the international ENDORSE study (50.2%) and similar to the majority of the other western European countries and the USA. It is also more used in university hospitals (66.9%) than in other hospitals (58.9%). Prophylaxis in patients at risk for VTE was presented in 43% patients with acute heart failure, 53% with non-infectious acute respiratory failure, 57% in patients with pulmonary infection, 56% in patients with stroke, 55% in patients with active cancer and 48% in patients with non-pulmonary sepsis. CONCLUSIONS: The ENDORSE study has shown a high level of patients at risk for VTE in the population of hospitalized patients in France. The rate of prophylaxis for VTE remained low, in particular in Medicine wards. Our data reinforced the rationale for the use of hospital-wide strategies to assess patients' VTE risk and to implement measures that ensure that at-risk patients receive appropriate prophylaxis, in particularly in medical patients.

Management and treatment of chronic hepatitis B virus infection in HIV positive and negative patients: the EPIB 2008 study.

BACKGROUND & AIMS: To compare the management and the virological and serological efficacy of treatments for chronic hepatitis B (CHB) in HIV positive and negative patients. METHODS: Two hundred and forty-six HIV positive and 205 HIV negative consecutive patients with past or present CHB, seen in October 2008 in participating departments, were included in a multicenter study. All the data were retrospectively collected from the first visit to October 2008 through a standardized questionnaire. RESULTS: Compared to HIV negative patients, HIV positive patients more often presented positive HBeAg (46.4% vs. 32.8%, p=0.01), HBV genotype A (54.8% vs. 17.1%, p<0.0001), co-infection with HCV (12.4% vs. 5.9%, p=0.0002) or HDV (12.6% vs. 2.9%, p=0.04). HIV positive patients were more often on HBV therapy (92.7% vs. 57.1%, p<0.0001), leading to undetectable serum HBV DNA levels (71.0% vs. 44.1%, p<0.0001). In HIV positive patients, multivariate analysis showed that older age, lower initial HBV DNA levels, and longer time on HBV therapy significantly correlated with undetectable HBV DNA. No difference in efficacy was observed between tenofovir used alone or in combination. HBsAg (but not HBe) loss was more often observed in HIV positive patients, sometimes followed by HBsAg re-appearance after withdrawal of HBV treatment. Excluding the 37 HBV-HCV-co-infected patients, the last clinical presentation and liver fibrosis scores were similar in HIV positive and negative patients. CONCLUSIONS: The assessment of CHB and the efficacy of HBV therapy have improved in HIV positive patients. HIV infection did not have a negative impact on the likelihood of HBV therapeutic success.
