Abstract

Background: Currently, no data are available on the burden of morbidity and mortality in people with HIV-1 (PWH) harboring a 4-class drug-resistant (4DR) virus (nucleoside reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, protease inhibitors, integrase strand transfer inhibitors). The study aimed to assess the incidence of clinical events and death in this population. Methods: This was a cohort study on PWH from the PRESTIGIO Registry with a documented 4DR virus. Burden of disease was defined as the occurrence of any new event including an AIDS-defining event (ADE) or non-AIDS-defining event (NADE) or death from any cause after 4DR evidence (baseline). Cox regression models evaluated factors associated with the risk of new clinical events/death. Results: Among 148 PWH followed for a median (interquartile range) of 47 (32-84) months after 4DR evidence, 38 PWH had 62 new events or died from any cause (incidence rate, 9.12/100 person-years of follow-up; 95% CI = 6.85-11.39): 12 deaths (6 AIDS-related and 6 non-AIDS-related), 18 ADEs, 32 NADEs; 20 of the 38 NADEs (45%) of the incident clinical events were malignancies. The 4-year cumulative incidence of death was 6% (95% CI, 3%-13%), and that of ≥1 event or death was 22% (95% CI, 16%-31%). A higher risk of new clinical events/death was more likely in PWH with previous clinical events (adjusted hazard ratio [aHR], 2.67; 95% CI, 1.07-6.67) and marginally associated with lower baseline CD4+/CD8+ ratio (aHR, 0.82; 95% CI, 0.65-1.02). Conclusions: PWH harboring 4DR have a high burden of disease with a worrying incidence of malignancies, strongly advising for close prevention and monitoring interventions as well as access to innovative therapeutic strategies, especially in people with a history of clinical events and low CD4+/CD8+ ratio.

Abstract

BACKGROUND: The level of evidence for HIV transmission risk through condomless sex in serodifferent gay couples with the HIV-positive partner taking virally suppressive antiretroviral therapy (ART) is limited compared with the evidence available for transmission risk in heterosexual couples. The aim of the second phase of the PARTNER study (PARTNER2) was to provide precise estimates of transmission risk in gay serodifferent partnerships.METHODS: The PARTNER study was a prospective observational study done at 75 sites in 14 European countries. The first phase of the study (PARTNER1; Sept 15, 2010, to May 31, 2014) recruited and followed up both heterosexual and gay serodifferent couples (HIV-positive partner taking suppressive ART) who reported condomless sex, whereas the PARTNER2 extension (to April 30, 2018) recruited and followed up gay couples only. At study visits, data collection included sexual behaviour questionnaires, HIV testing (HIV-negative partner), and HIV-1 viral load testing (HIV-positive partner). If a seroconversion occurred in the HIV-negative partner, anonymised phylogenetic analysis was done to compare HIV-1 pol and env sequences in both partners to identify linked transmissions. Couple-years of follow-up were eligible for inclusion if condomless sex was reported, use of pre-exposure prophylaxis or post-exposure prophylaxis was not reported by the HIV-negative partner, and the HIV-positive partner was virally suppressed (plasma HIV-1 RNA FINDINGS: Between Sept 15, 2010, and July 31, 2017, 972 gay couples were enrolled, of which 782 provided 1593 eligible couple-years of follow-up with a median follow-up of 2·0 years (IQR 1·1-3·5). At baseline, median age for HIV-positive partners was 40 years (IQR 33-46) and couples reported condomless sex for a median of 1·0 years (IQR 0·4-2·9). During eligible couple-years of follow-up, couples reported condomless anal sex a total of 76 088 times. 288 (37%) of 777 HIV-negative men reported condomless sex with other partners. 15 new HIV infections occurred during eligible couple-years of follow-up, but none were phylogenetically linked within-couple transmissions, resulting in an HIV transmission rate of zero (upper 95% CI 0·23 per 100 couple-years of follow-up).INTERPRETATION: Our results provide a similar level of evidence on viral suppression and HIV transmission risk for gay men to that previously generated for heterosexual couples and suggest that the risk of HIV transmission in gay couples through condomless sex when HIV viral load is suppressed is effectively zero. Our findings support the message of the U=U (undetectable equals untransmittable) campaign, and the benefits of early testing and treatment for HIV.FUNDING: National Institute for Health Research.

Abstract

HIV-1 drug resistance represents a major obstacle to infection and disease control. This retrospective study analyzes trends and determinants of resistance in antiretroviral treatment (ART)-exposed individuals across 7 countries in Europe. Of 20 323 cases, 80% carried at least one resistance mutation: these declined from 81% in 1997 to 71% in 2008. Predicted extensive 3-class resistance was rare (3.2% considering the cumulative genotype) and peaked at 4.5% in 2005, decreasing thereafter. The proportion of cases exhausting available drug options dropped from 32% in 2000 to 1% in 2008. Reduced risk of resistance over calendar years was confirmed by multivariable analysis. © 2013 The Author.

Abstract

Introduction: This study aimed at defining protease (PR) resistance mutations associated with darunavir (DRV) failure and PR resistance evolution at DRV failure in a large database of treatment-experienced human immunodeficiency virus (HIV) patients. Results: Overall, 1,104 patients were included: 118 (10.7%) failed at a median observation time of 16 months. The mean number of PR mutations at baseline was 2.7, but it was higher in patients who subsequently failed DRV. In addition, the number of PR mutations increased at failure. The increase in the mean number of mutations was completely related to mutations considered to be associated with DRV resistance following the indications of the main DRV clinical trials. Discussion The higher statistical difference at baseline between failing versus non-failing patients was observed for the V32I and I84V mutations. At DRV failure, the major increase was still observed for V32I; I54L, V11I, T74P and I50V also increased. Despite the increment in the mean number of mutations per patient between baseline and failure, in 21 patients (17.8%) at baseline and 36 (30.5%) at failure, no PR mutation was detected. Conclusion: The HIV-DB interpretation algorithm identified few patients with full DRV resistance at baseline and few patients developed full resistance at DRV failure, indicating that complete resistance to DRV is uncommon. © Springer-Verlag 2011.

Abstract

An investigation was undertaken to determine whether specific pol mutations hinder long-term immune recovery regardless of virological response. In total, 826 patients with >50 HIV RNA copies/ml, who underwent genotypic resistance testing between 1 January 2000 and 31 December 2003 after >3 years of antiretroviral treatment, and were followed up for >3 years after genotypic resistance testing, were analyzed retrospectively. The outcome of the study was the lack of immune recovery after >3 years of follow-up, defined as a slope by linear regression 50 copies/ml divided by the number of HIV RNA measurements during follow-up. Logistic regression was used for univariable and multivariable analysis. Median (Q1, Q3) values at baseline were the following: age 40 (37, 45) years, years on antiretroviral therapy 4.45 (3.65, 5.47), HIV RNA 3.91 (3.39, 4.53) log 10 copies/ml, CD4+ T-cell 358 (211, 524)/μl. After 3.13 years of follow-up, 375 patients (45.4%) showed a lack of immune recovery. The risk of lack of immune recovery increased independently with increasing baseline CD4+ counts (OR=1.104 per 50-cell increase, 95% CI=1.069-1.142, P

Abstract

Protease inhibitor (PI)-resistant HIV-1 has hardly ever been detected at failed boosted PI-based first-line antiretroviral regimens in clinical trials. However, this phenomenon has not been investigated in clinical practice. To address this gap, data from patients starting a first-line lopinavir/ritonavir (LPV/rtv)-based therapy with available baseline HIV-1 RNA load, a viral genotype and follow-up viral load after 3 and 6 months of treatment were extracted from the Italian Antiretroviral Resistance Cohort Analysis (ARCA) observational database. Based on survival analysis, 39 (7.1%) and 43 (7.8%) of the 548 examined patient cases had an HIV-1 RNA >500 and >50 copies/ml, respectively, after 6 months of treatment. Cox proportional hazard models detected baseline HIV-1 RNA (RH 1.79, 95%CI 1.10-2.92 per 1 - log10 increase, P = 0.02) and resistance to the nucleoside backbone (RH 1.04, 95%CI 1.02-1.06 per 10-point increase using the Stanford HIVdb algorithm, P < 0.001) as independent predictors of HIV-1 RNA at >500 copies/ml, but not at the >50 copies/ml cutoff criteria. Higher baseline viral load, older patient age, heterosexual route of infection and use of tenofovir/emtricitabine were predictors of failure at month 3 using the 50-copy and/or 500-copy threshold. Resistance to LPV/rtv did not occur or increase in any of the available 36 follow-up HIV-1 genotypes. Resistance to the nucleoside backbone (M184V) developed in four cases. Despite the likely differences in patient population and adherence, both the low rate of virological failure and the lack of development of LPV/rtv resistance documented in clinical trials are thus confirmed in clinical practice.

Abstract

Objectives: To test retrospectively the ability of four freely available rules-based expert systems to predict short- and medium-term virological outcome following an antiretroviral treatment switch in pre-treated HIV-1 patients. Methods: The HIV-1 genotype interpretation systems (GISs) HIVdb, ANRS, Rega and AntiRetroScan were tested for their accuracy in predicting response to highly active antiretroviral therapy using 8 week (n = 765) and 24 week (n = 634) follow-up standardized treatment change episodes extracted from the Italian Antiretroviral Resistance Cohort Analysis (ARCA) database. A genotypic sensitivity score (GSS) was derived for each genotype-treatment pair for the different GISs and tested as a predictor of virological treatment outcome by univariable and multivariable logistic regression as well as by receiver operating characteristic curve analysis. The two systems implementing drug potency weights (AntiRetroScan and Rega) were evaluated with and without this correction factor. Results: All four GSSs were strong predictors of virological treatment outcome at both 8 and 24 weeks after adjusting for baseline viro-immunological parameters and previous drug exposure (odds ratios ranging from 2.04 to 2.43 per 1 unit GSS increase; P < 0.001 for all the systems). The accuracy of AntiRetroScan and Rega was significantly increased by drug potency weighting with respect to the unweighted versions (P ≤ 0.001). HIVdb and ANRS also increased their performance with the same drug potency weighting adopted by AntiRetroScan and Rega, respectively (P < 0.001 for both analyses). Conclusions: Currently available GISs are valuable tools for assisting antiretroviral treatment choices. Drug potency weighting can increase the accuracy of all systems. © The Author 2009.

Abstract

Understanding the determinants of virus transmission is a fundamental step for effective design of screening and intervention strategies to control viral epidemics. Phylogenetic analysis can be a valid approach for the identification of transmission chains, and very-large data sets can be analysed through parallel computation. Here we propose and validate a new methodology for the partition of large-scale phylogenies and the inference of transmission clusters. This approach, on the basis of a depth-first search algorithm, conjugates the evaluation of node reliability, tree topology and patristic distance analysis. The method has been applied to identify transmission clusters of a phylogeny of 11,541 human immunodeficiency virus-1 subtype B pol gene sequences from a large Italian cohort. Molecular transmission chains were characterized by means of different clinical/demographic factors, such as the interaction between male homosexuals and male heterosexuals. Our method takes an advantage of a flexible notion of transmission cluster and can become a general framework to analyse other epidemics. © 2011 Macmillan Publishers Limited. All rights reserved.

Abstract

Background and objectives: Guidelines indicate a plasma HIV-1 RNA load of 500-1000 copies/mL as the minimal threshold for antiretroviral drug resistance testing. Resistance testing at lower viral load levels may be useful to guide timely treatment switches, although data on the clinical utility of this remain limited. We report here the influence of viral load levels on the probability of detecting drug resistance mutations (DRMs) and other mutations by routine genotypic testing in a large multicentre European cohort, with a focus on tests performed at a viral load

Abstract

Background HIV-1 genotypic susceptibility scores (GSSs) were proven to be significant prognostic factors of fixed time-point virologic outcomes after combination antiretroviral therapy (cART) switch/initiation. However, their relative-hazard for the time to virologic failure has not been thoroughly investigated, and an expert system that is able to predict how long a new cART regimen will remain effective has never been designed. Methods We analyzed patients of the Italian ARCA cohort starting a new cART from 1999 onwards either after virologic failure or as treatment-naïve. The time to virologic failure was the endpoint, from the 90th day after treatment start, defined as the first HIV-1 RNA > 400 copies/ml, censoring at last available HIV-1 RNA before treatment discontinuation. We assessed the relative hazard/importance of GSSs according to distinct interpretation systems (Rega, ANRS and HIVdb) and other covariates by means of Cox regression and random survival forests (RSF). Prediction models were validated via the bootstrap and c-index measure. Results The dataset included 2337 regimens from 2182 patients, of which 733 were previously treatment-naïve. We observed 1067 virologic failures over 2820 persons-years. Multivariable analysis revealed that low GSSs of cART were independently associated with the hazard of a virologic failure, along with several other covariates. Evaluation of predictive performance yielded a modest ability of the Cox regression to predict the virologic endpoint (c-index≈0.70), while RSF showed a better performance (c-index≈0.73, p < 0.0001 vs. Cox regression). Variable importance according to RSF was concordant with the Cox hazards. Conclusions GSSs of cART and several other covariates were investigated using linear and non-linear survival analysis. RSF models are a promising approach for the development of a reliable system that predicts time to virologic failure better than Cox regression. Such models might represent a significant improvement over the current methods for monitoring and optimization of cART.

38. Vindesine effect in myeloid leukemia.

Author

Baccarani, Michele, Zaccaria, Alfonso, Corbelli, Giovanna, Tura, Sante, Baccarani, M, Zaccaria, A, Corbelli, G, and Tura, S

Abstract

Vindesine (VDS), a semisynthetic vinca alkaloid derivative, was given weekly at a dose of 3 mg/m2 as single-agent chemotherapy to seven patients with chronic myeloid leukemia (CML), 17 patients with chronic myeloid leukemia in blastic metamorphosis (CML/BM), and 12 patients with acute nonlymphocytic leukemia (ANLL). A substantial and rapid decrease of leukemic cells was obtained in 31 of 36 patients, and this was independent of cell phenotype and morphology. VDS may improve the results of polychemotherapy of ANLL, and is useful for palliative treatment of CML/BM. [ABSTRACT FROM AUTHOR]

Abstract

The prognostic value of nine clinical and haematological features, recorded at diagnosis in chronic myeloid leukaemia (CML), was analysed in two distinct series of patients. One series (116 cases) was collected at a single hospital over a 12-year period. The second series (139 cases) was collected from a multicentre trial over a 20-month period. Six features were associated with a poor prognosis: splenomegaly (more than 15 cm below the costal margin), hepatomegaly (more than 6 cm below the costal margin), thrombocytopenia (150 X 10(9)/l) or thrombocytosis (500 X 10(9)/l), a leucocyte count above 100 X 10(9)/l, peripheral blood non-granulated precursors (blast cells) above 1%, and peripheral blood granulated precursors (promyelocytes and myelocytes) above 20%. Depending on the number of negative prognostic factors, patients were divided into three categories: group I (0 or 1 factor), group II (2 or 3 factors) and group III (4,5 or 6 factors). Survival was significantly different in the three groups (P0.0005), and this was independent of age (below and above 50). The prognostic value of the classification was confirmed in a third series of 153 patients. We suggest that this classification provides a useful tool to identify prognostic categories in CML, and thus allows a proper allocation of patients to different therapies.

41. Rectal absorption of some glycosaminoglycan sulphates and heparin in rats

Author

STANZANI, L, MASCELLANI, G, CORBELLI, G P, and BIANCHINI, P

Abstract

A standardized extract of glycosaminoglycan sulphates containing heparin, with a low affinity for antithrombin III, and a commercial heparin were administered to rats, by the rectal route. When the glycosaminoglycan sulphates were given in oil emulsion with sodium laurylsarcosinate as surfactant, 1 mg kg−1and 3 mg kg−1were sufficient for the clearing and anticoagulant activities respectively. The rectal absorption of glycosaminoglycans after dosing with a suitable ‘promoter' produced dose-dependent effects and their kinetics were comparable to those obtained after intramuscular administration. The oil emulsion improved the bioavailability of glycosaminoglycan sulphates at least 20 times.

42. Adolescent and adult acute lymphoblastic leukemia: prognostic features and outcome of therapy. A study of 293 patients

Author

Baccarani, M, Corbelli, G, Amadori, S, Drenthe-Schonk, A, Willemze, R, Meloni, G, Cardozo, PL, Haanen, C, Mandelli, F, and Tura, S

Abstract

The case histories of 293 adolescent and adult patients with acute lymphoblastic leukemia (ALL) first seen and treated between 1969 and 1979 are reviewed. A complete remission (CR) was achieved in 79% of cases. Male sex, advanced age (greater than or equal to 30 yr old), and early CNS involvement were the major determinants of remission failure. Median duration of first CR was 16 mo, with 23 patients (actuarial proportion 25%) alive and relapse-free at 5 yr. The major determinant of first CR length was white blood cell (WBC) count (best cut-off value at 35 X 10(9)/liter). First CR length was also negatively affected by early CNS involvement, morphological FAB L3 subtype, and B-cell (Smlg+) leukemia, but these features were significantly associated with a high WBC count. First CR length in patients 11–15 yr old did not differ significantly from that of patients 16–59 yr old. The negative prognostic value of T-cell (E+) leukemia was not confirmed in this adult series. CNS prophylaxis provided an effective protection against CNS relapse. Maintenance chemotherapy was apparently more effective when 4 or more than 4 drugs were employed. “Low risk” patients (WBC count less than 35 X 10(9)/liter still relapsed rather frequently (32% at 1 yr, 49% at 2 yr), with 33% of them alive and relapse-free at 5 yr. “High risk” patients (WBC count greater than or equal to 35 X 10(9)/liter +/- early CNS involvement +/- morphological L3 subtype +/- B-cell leukemia) relapsed very quickly (50% at 6 mo. 70% at 1 yr), with only 6% of them relapse-free at 5 yr.

44. The microwave spectrum of trifluoroacetonitrile in excited vibrational states

Author

Whittle, M.J., Baker, J.G., and Corbelli, G.

Abstract

The microwave transitions J→ J+ 1 have been observed in the symmetric top molecule trifluoroacetonitrile, CF3CN, for molecules excited into several of the low-lying vibrational states. Measurements made in the degenerate states v7= 1 v8= 1 have been fitted to the formula derived by Grenier-Besson and Amat (1)for transitions J→ J+ 1 in degenerate vibrational states of molecules with C3vsymmetry. The measurements for the state v8= 1 have been extended to 150 GHz where it is shown that the above formula becomes inadequate to describe accurately the observed spectrum.

Abstract

Defibrination is a rare event in acute lymphoblastic leukaemia (ALL). This paper describes four cases of acute defibrination in a series of 52 adult patients with ALL. All four patients had blood clotting tests consistent with or suggesting defibrination prior to therapy, but haemorrhages and unequivocal laboratory evidence of defibrination developed only after leukaemic blast cells had been destroyed early during therapy for remission induction. All patients received supportive therapy, and three of them were also given a continuous IV heparin infusion. Haemorrhages were controlled and blood clotting tests were improved within 12--48 h.
