Human Immunodeficiency Virus Continuum of Care in 11 European Union Countries at the End of 2016 Overall and by Key Population: Have We Made Progress?

BACKGROUND: High uptake of antiretroviral treatment (ART) is essential to reduce human immunodeficiency virus (HIV) transmission and related mortality; however, gaps in care exist. We aimed to construct the continuum of HIV care (CoC) in 2016 in 11 European Union (EU) countries, overall and by key population and sex. To estimate progress toward the Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 target, we compared 2016 to 2013 estimates for the same countries, representing 73% of the population in the region. METHODS: A CoC with the following 4 stages was constructed: number of people living with HIV (PLHIV); proportion of PLHIV diagnosed; proportion of those diagnosed who ever initiated ART; and proportion of those ever treated who achieved viral suppression at their last visit. RESULTS: We estimated that 87% of PLHIV were diagnosed; 92% of those diagnosed had ever initiated ART; and 91% of those ever on ART, or 73% of all PLHIV, were virally suppressed. Corresponding figures for men having sex with men were: 86%, 93%, 93%, 74%; for people who inject drugs: 94%, 88%, 85%, 70%; and for heterosexuals: 86%, 92%, 91%, 72%. The proportion suppressed of all PLHIV ranged from 59% to 86% across countries. CONCLUSIONS: The EU is close to the 90-90-90 target and achieved the UNAIDS target of 73% of all PLHIV virally suppressed, significant progress since 2013 when 60% of all PLHIV were virally suppressed. Strengthening of testing programs and treatment support, along with prevention interventions, are needed to achieve HIV epidemic control.

The Human Immunodeficiency Virus Continuum of Care in European Union Countries in 2013: Data and Challenges.

BACKGROUND.: The Joint United Nations Programme on HIV/AIDS (UNAIDS) has set a "90-90-90" target to curb the human immunodeficiency virus (HIV) epidemic by 2020, but methods used to assess whether countries have reached this target are not standardized, hindering comparisons. METHODS.: Through a collaboration formed by the European Centre for Disease Prevention and Control (ECDC) with European HIV cohorts and surveillance agencies, we constructed a standardized, 4-stage continuum of HIV care for 11 European Union countries for 2013. Stages were defined as (1) number of people living with HIV in the country by end of 2013; (2) proportion of stage 1 ever diagnosed; (3) proportion of stage 2 that ever initiated ART; and (4) proportion of stage 3 who became virally suppressed (≤200 copies/mL). Case surveillance data were used primarily to derive stages 1 (using back-calculation models) and 2, and cohort data for stages 3 and 4. RESULTS.: In 2013, 674500 people in the 11 countries were estimated to be living with HIV, ranging from 5500 to 153400 in each country. Overall HIV prevalence was 0.22% (range, 0.09%-0.36%). Overall proportions of each previous stage were 84% diagnosed, 84% on ART, and 85% virally suppressed (60% of people living with HIV). Two countries achieved ≥90% for all stages, and more than half had reached ≥90% for at least 1 stage. CONCLUSIONS.: European Union countries are nearing the 90-90-90 target. Reducing the proportion undiagnosed remains the greatest barrier to achieving this target, suggesting that further efforts are needed to improve HIV testing rates. Standardizing methods to derive comparable continuums of care remains a challenge.

Second-line Treatment of Non-Small Cell Lung Cancer: Focus on the Clinical Development of Dacomitinib.

Dacomitinib is a second-generation, irreversible, covalent pan-HER tyrosine-kinase inhibitor (TKI). It showed potent EGFR signaling inhibition in experimental models, including first-generation TKI-resistant non-small cell lung cancer (NSCLC) cell lines. This preclinical efficacy did not translate into clinically meaningful treatment benefits for advanced, pretreated, molecularly unselected NSCLC patients enrolled in two parallel phase III trials. Dacomitinib and erlotinib showed overlapping efficacy data in chemotherapy-pretreated EGFR wild-type (WT) patients in the ARCHER 1009 trial. Similarly, it failed to demonstrate any survival benefits as compared to placebo in EGFR WT subsets progressing on chemotherapy and at least one previous first-generation TKI (erlotinib or gefitinib) in the BR.26 trial. In the case of EGFR-mutant NSCLCs, a pooled analysis of the ARCHER 1009 and ARCHER 1028 trials comparing the efficacy of dacomitinib vs. erlotinib in chemotherapy-pretreated, EGFR TKI-naïve patients showed a trend to a longer progression-free survival (PFS) and overall survival in favor of dacomitinib that did not reach statistical significance, with a higher rate of treatment related adverse events (mainly skin rash, paronychia, and gastrointestinal toxicities). On the other hand, the clinical activity in patients with EGFR-mutant NSCLCs with acquired TKI resistance that were included in phase II/III trials was equally poor (response rate <10%; PFS 3-4 months). Therefore, with the results of the ARCHER 1050 trial (NCT01774721) still pending, the current clinical development of dacomitinib is largely focused on EGFR-mutant, TKI-naïve patients. Here, we review the most relevant clinical data of dacomitinib in advanced NSCLC. We discuss the potential role of dacomitinib in pretreated EGFR WT and EGFR-mutant (TKI-naïve and TKI-resistant) patients. Finally, we briefly comment the available clinical data of dacomitinib in HER2-mutant NSCLC patients.

Epidemiologic trends of cancer diagnoses among HIV-infected children in Spain from 1997 to 2008.

BACKGROUND: The introduction of highly active antiretroviral therapy (HAART) has influenced the incidence of cancer in people with human immunodeficiency virus (HIV) infection. The aim of this study was to evaluate changes in the pattern of cancer rates in HIV-infected children on HAART during over a decade of follow-up. PATIENTS AND METHODS: We carried out a case-control study. Data were obtained from the records of the minimum basic data set of hospitals in Spain from 1999 to 2008. The epidemiologic trends of cancer diagnoses were evaluated through 3 calendar periods: early-period HAART: 1997-1999, midperiod HAART: 2000-2002, and late-period HAART: 2003-2008). RESULTS: HIV-infected children had higher rates of cancer diagnosis than HIV-negative children (P < 0.001) for both acquired immunodeficiency disease syndrome (AIDS)-defining malignancies (ADM) and non-AIDS-defining malignancies (non-ADM). The highest rates of cancer diagnosis in HIV-positive children were for non-Hodgkin lymphoma, malignant neoplasm of bone and articular cartilage, and Hodgkin lymphoma. When we compared the 3 calendar periods, we found that the rate of ADM diagnoses decreased (from 9.1 to 3.6 to 1.0 cancers per 1000 HIV-children/yr; P < 0.05) and that the rate of non-ADM diagnoses increased (from 0.6 to 5.0 to 8.7 cancers per 1000 HIV-children/yr; P < 0.05). Moreover, the overall rate of cancer diagnoses (ADM plus non-ADM) did not change during the study period (9.7, 8.7, and 9.7 cancers per 1000 HIV-children/yr). CONCLUSIONS: HIV-infected children had a dramatic decrease in the rate of ADM diagnoses and an increase in the rate of non-ADM diagnoses. The overall cancer diagnosis rate has not decreased during the past decade and the incidence of cancer still remains high in HIV-infected children in Spain.

Prevalence of maternal hepatitis C infection according to HIV serostatus in six Spanish regions (2003-2006).

The objective of this article is to describe the prevalence of maternal Hepatitis C infection globally and by HIV serostatus. Unlinked anonymous testing on 474,539 samples from newborn babies was carried out, selected through stratified sampling by year and HIV status, in six Spanish Autonomous Regions, from 2003 to 2006. Results were 0.15% for global anti-hepatitis C virus (HCV), 29.69% and 0.10% for HIV(+) and HIV(-) women, respectively. Anti-HCV prevalence rate is low in these regions compared to Hospital cohorts. Although a high prevalence rate in HIV co-infected women is found, it tends to decrease along the period studied.
