Safety, efficacy, and persistence of emtricitabine/tenofovir versus other nucleoside analogues in naive subjects aged 50 years or older in Spain: the TRIP study.

OBJECTIVES: Current antiretroviral guidelines state that being older than 50 to 55 years of age is an indication to start antiretroviral therapy (ART), regardless of CD4 status. However, no references to the preferred combination ART (cART) for these patients have been described. Our study compares emtricitabine and tenofovir disoproxil fumarate (FTC/TDF) versus other nucleoside reverse transcriptase inhibitor (NNRTI) regimens in HIV ART-naïve patients who are ≥50 years. DESIGN: National, retrospective cohort analysis of patients who were ≥50 years old when they began the first cART (January 1, 2006 to December 31, 2009). METHODS: We compared safety, effectiveness, and persistence of treatment in FTC/TDF versus non-FTC/TDF users. Among FTC/TDF users, we compared protease inhibitor (PI) versus NNRTI users and lopinavir/r versus efavirenz users. RESULTS: We included 161 patients: median age was 54.6 years, 83% were men, median CD4 count was 191 cells/µL, median viral load was 4.7 log, and median follow-up was 19 months (maximum, 48 months). Of these participants, 112 started with FTC/TDF and 49 with other nucleotide reverse transcriptase inhibitors (NRTIs). During follow-up, 21.9% of subjects developed at least one laboratory event ≥grade 3, 5.6% interrupted cART due to adverse events,19.3% had virologic failure, and 49.1% modified cART. There were no statistically significant differences between FTC/TDF and non-FTC/TDF users for any output except for persistence: The proportion of subjects who changed cART was 71.4% for non-FTC/TDF users and 38.6% for FTC/TDF users (log rank 0.001; adjusted hazard ratio, 2.10; 95% CI, 1.34-3.29). CONCLUSIONS: In a population of HIV-infected subjects who were ≥50 years old, our study suggests that the use of FTC/TDF is generally safe and effective, with a longer persistence as compared to other regimens.

Educational gradient in HIV diagnosis delay, mortality, antiretroviral treatment initiation and response in a country with universal health care.

BACKGROUND: The aim of this study was to analyse associations between educational level and delayed HIV diagnosis (DD), late initiation of combined antiretroviral therapy (cART), overall and in subjects with timely HIV diagnosis, virological and immunological responses to cART, and mortality from HIV diagnosis and cART initiation. METHODS: This was a multicentre cohort study of HIV-positive treatment-naive subjects in Spain between 2004-2009. Logistic and Cox regression analyses were used. RESULTS: Of 4,549 subjects, 44.5% had low education level (LOW), 34.4% medium education level (MED) and 21.1% high education level (HIG). In men, DD was more common in MED (OR 1.3 [95% CI 1.0, 1.7]) or LOW [OR 1.8 (95% CI 1.4, 2.3)] compared to HIG. In women, the opposite was observed; women with HIG were 40% more likely to have DD than those with LOW (OR 1.4 [95% CI 0.8, 2.5]). In individuals with timely HIV diagnoses, percentages of late cART initiators were similar (LOW 9.5%, MED 11.4% and HIG 7.0%; P=0.114). Immunological (LOW 68%, MED 76% and HIG 84%) and virological (LOW 76%, MED 83% and HIG 86%) responses to cART increased significantly with educational level; these increases remained significant in multivariate analyses. Mortality for LOW subjects was higher than for HIG, from HIV diagnosis (hazard ratio [HR] 2.3 [95% CI 1.1, 4.9]) and from cART initiation (HR 1.8 [95% CI 0.8, 3.9]). CONCLUSIONS: We found important differences by educational level in diagnosis delay, virological and immunological responses to cART and mortality in a country with universal health care. Women with high educational level are at higher risk of having delayed HIV diagnoses. Educational level should be taken into account when designing HIV testing and clinical management strategies.

Association of Patients' Geographic Origins with Viral Hepatitis Co-infection Patterns, Spain.

To determine if hepatitis C virus seropositivity and active hepatitis B virus infection in HIV-positive patients vary with patients' geographic origins, we studied co-infections in HIV-seropositive adults. Active hepatitis B infection was more prevalent in persons from Africa, and hepatitis C seropositivity was more common in persons from eastern Europe.

HIV-1-related Hodgkin lymphoma in the era of combination antiretroviral therapy: incidence and evolution of CD4⁺ T-cell lymphocytes.

The risk of Hodgkin lymphoma (HL) is increased in patients infected with HIV-1. We studied the incidence and outcomes of HL, and compared CD4⁺ T-cell trajectories in HL patients and controls matched for duration of combination antiretroviral therapy (cART). A total of 40 168 adult HIV-1-infected patients (median age, 36 years; 70% male; median CD4 cell count, 234 cells/µL) from 16 European cohorts were observed during 159 133 person-years; 78 patients developed HL. The incidence was 49.0 (95% confidence interval [CI], 39.3-61.2) per 100,000 person-years, and similar on cART and not on cART (P = .96). The risk of HL declined as the most recent (time-updated) CD4 count increased: the adjusted hazard ratio comparing more than 350 with less than 50 cells/µL was 0.27 (95% CI, 0.08-0.86). Sixty-one HL cases diagnosed on cART were matched to 1652 controls: during the year before diagnosis, cases lost 98 CD4 cells (95% CI, -159 to -36 cells), whereas controls gained 35 cells (95% CI, 24-46 cells; P < .0001). The incidence of HL is not reduced by cART, and patients whose CD4 cell counts decline despite suppression of HIV-1 replication on cART may harbor HL.

Infección por el virus de la inmunodeficiencia humana en diferentes grupos de edad: implicaciones potenciales para la prevención. Cohorte CoRIS, España, 2004–2008 / HIV infection in different age groups: Potential implications for prevention. CoRIS Cohort, Spain, 2004–2008

Fundamento y objetivo: Describir las características de pacientes adultos con infección por el virus de la inmunodeficiencia humana (VIH) según su edad al momento de la inclusión en la Cohorte de la Red de Investigación en Sida (CoRIS). Pacientes y métodos: Análisis de una cohorte abierta, prospectiva, multicéntrica de adultos con infección por el VIH sin tratamiento antirretroviral previo, atendidos por primera vez entre enero de 2004 y noviembre de 2008, en 28 hospitales españoles (CoRIS). Se analizaron sus características en la primera visita y la distribución de las enfermedades definitorias de sida (EDS) a lo largo de la vida, según la edad al momento de la inclusión. El retraso diagnóstico se definió como pacientes con diagnóstico de sida o cifra de CD4+ inferior a 200 cel/μl durante el año posterior al diagnóstico de la infección por el VIH. Resultados: Participaron 4.418 personas; el 30,4% con 30 años o menos, el 60,6% de entre 31 y 50 años y el 8,9% de mayores de 50 años. El 31,6% de los pacientes eran inmigrantes (el 44,1% entre los jóvenes), el 79,6% correspondía a transmisión sexual y el 15,2% tenía diagnóstico de sida en la primera visita (el 28,1% entre los mayores de 50 años). El 34,6% de los pacientes tenía retraso diagnóstico (el 53,3% en los mayores de 50 años). La distribución de las EDS varió con la edad: las tuberculosis son más frecuentes en jóvenes y la neumonía por Pneumocystis jiroveci, la leucoencefalopatía multifocal progresiva, la encefalopatía por VIH, la neumonía recurrente y el linfoma cerebral primario son más frecuentes en los mayores. Conclusiones: Las características inmunológicas y las EDS varían con la edad. El porcentaje de personas con retraso diagnóstico es inaceptablemente alto, lo que indica que deben diseñarse intervenciones dirigidas a efectuar un diagnóstico más precoz (AU)

Background and objective: To describe the characteristics of HIV infected adults according to their age at recruitment in CoRIS. Patients and methods: Analysis of an open, prospective, multicentric cohort of HIV+ adults without previous antiretroviral treatment, attended for the first time from January/2004 to November/2008, in 28 Spanish hospitals (CoRIS). We analyzed their characteristics at recruitment and the distribution of AIDS defining illnesses (ADI) prior to cohort entry and during follow up, according to their age at recruitment. Delayed diagnosis was defined as a patient with AIDS diagnosis and/or CD4+ cell count lower than 200 cells/μl within the first year after HIV diagnosis. Results: Of 4,418 patients included, 30.4% were <=30 years old, 60.6% between 31 and 50 and 8.9% older than 50 at cohort entry; 31.6% of patients were immigrants (44.1% in the youngest group), 79.6% had been sexually transmitted and 15.2% had an AIDS diagnosis at cohort entry (28.1% between those older than 50). In 34.6% of cases there was a late diagnosis (53.3% in the oldest group). The ADIs varied according to age; tuberculosis was more frequent in the youngest. Pneumocystis jiroveci pneumonia, progressive multifocal leukoencephalopathy, HIV related encephalopathy, recurrent pneumonia and primary lymphoma of brain were more frequent among the oldest. Conclusions: The immunological characteristics and the distribution of ADIs varied according to age. The proportion of late diagnosis was unacceptably high, suggesting the need of specific interventions designed to promote earlier diagnosis (AU)

HIV infection in immigrants in Spain: Epidemiological characteristics and clinical presentation in the CoRIS Cohort (2004–2006)

Introducción En España, la proporción de inmigrantes en los servicios clínicos de infección por virus de la inmunodeficiencia humana (VIH) es creciente. El objetivo del presente artículo es describir las características sociodemográficas, epidemiológicas y clínicas de una cohorte de personas con infección por VIH de la Red de Investigación en Sida (CoRIS) según su lugar de origen. Métodos CoRIS es una cohorte abierta, prospectiva y multicéntrica de adultos con infección por VIH sin tratamiento antirretrovírico previo, que se atendieron en 19 hospitales de 9 Comunidades Autónomas españolas entre enero de 2004 y octubre de 2006. Se describen las características por región de origen y se comparan con los casos españoles Resultados Se incluyeron 2.507 pacientes: el 76,3% fueron varones, con una mediana de edad de 36 años. Por el lugar de origen, el 71,5% fueron españoles; el 16,0% fueron latinoamericanos; el 5,8% fueron de África Subsahariana; el 3,7% fueron de Europa occidental; el 1,7% fueron de Europa del este, y el 1,4% fueron de África del norte. En comparación con los españoles, hubo diferencias significativas en sexo, edad y categoría de transmisión. La mediana de linfocitos CD4 al ingreso a la cohorte fue de 352×106/l, sin que hubiera diferencias según el origen. La mediana de carga vírica fue de 48,962 copias/ml, significativamente menor en el grupo de África subsahariana. Tras 11,4 meses de seguimiento, el 57,9% había iniciado tratamiento, sin que hubiera diferencias por origen. La prevalencia de coinfección con hepatitis C fue del 29,9% en españoles, del 7,3% en latinoamericanos, del 11,7% en los sujetos de África subsahariana y del 45,7% en los sujetos de Europa del este (p-60;0,05). El 13,4% tuvo prueba de tuberculina positiva; el 28,6% en los sujetos del África subsahariana y el 30,8% en los sujetos de África del norte. La tuberculosis fue más frecuente entre los sujetos de Europa del este (9,5%) y del África subsahariana (8,3%) que en españoles (4,8%) (p-60;0,05). Conclusiones Casi un tercio de las personas con infección por VIH que se atendieron recientemente en España fueron extranjeros. Sus características sociodemográficas, epidemiológicas y clínicas reflejan la epidemia en sus lugares de origen. Sin embargo, su situación inmunológica cuando acceden al hospital y en el inicio del tratamiento no difiere de la de los pacientes españoles (AU)

Introduction A growing number of immigrants are using the public health services for HIV in Spain. We describe the sociodemographic, epidemiological, and clinical characteristics of a cohort of naïve HIV-infected subjects (CoRIS cohort) according to their place of origin. Methods CoRIS is an open, hospital-based cohort of naïve, HIV-infected persons attended in 19 hospitals from 9 of the 19 autonomous regions in Spain. We describe the characteristics of the cohort members by place of origin, and compare them with the Spanish cases identified from January 2004 to October 2006, using the chi-square and Fisher exact tests. Results Of 2507 patients, 76.3% were men and median age was 36 years. By origin, 71.5% were Spanish, 16.0% Latin Americans (LA), 5.8% sub-Saharan Africans (SSA), 3.7% Western Europeans (WE), 1.7% Eastern Europeans (EE) and 1.4% North Africans (NA). Compared to Spaniards, there were significant differences by origin in sex, age, and transmission category. Median CD4 count at cohort entry was 352 cell/μL, with no differences according to origin. Median viral load was 48 962 copies/mL and was significantly lower for SSA. Over 11.4 months of follow-up, 57.9% initiated HAART with no differences by origin. Hepatitis C prevalence was 29.9% in Spaniards, 7.3% in Latin Americans, 11.7% in SSA, and 45.7% in EE (P-60;0.05). Overall, 13.4% were Mantoux-positive (28.6% in SSA and 30.8% in NA). Tuberculosis was more common among cases from EE (9.5%) and SSA (8.3%) compared to Spaniards (4.8%) (P-60;0.05).ConclusionsAlmost one third of naïve HIV-infected patients in CoRIS are foreign-born. Their sociodemographic, epidemiological and clinical characteristics reflect the epidemic in their places of origin. However, their immunological status at cohort entry and initiation of HAART is no different from that of Spaniards(AU)

Prognosis of HIV-associated non-Hodgkin lymphoma in patients starting combination antiretroviral therapy.

OBJECTIVE: We examined survival and prognostic factors of patients who developed HIV-associated non-Hodgkin lymphoma (NHL) in the era of combination antiretroviral therapy (cART). DESIGN AND SETTING: Multicohort collaboration of 33 European cohorts. METHODS: We included all cART-naive patients enrolled in cohorts participating in the Collaboration of Observational HIV Epidemiological Research Europe (COHERE) who were aged 16 years or older, started cART at some point after 1 January 1998 and developed NHL after 1 January 1998. Patients had to have a CD4 cell count after 1 January 1998 and one at diagnosis of the NHL. Survival and prognostic factors were estimated using Weibull models, with random effects accounting for heterogeneity between cohorts. RESULTS: Of 67 659 patients who were followed up during 304 940 person-years, 1176 patients were diagnosed with NHL. Eight hundred and forty-seven patients (72%) from 22 cohorts met inclusion criteria. Survival at 1 year was 66% [95% confidence interval (CI) 63-70%] for systemic NHL (n = 763) and 54% (95% CI: 43-65%) for primary brain lymphoma (n = 84). Risk factors for death included low nadir CD4 cell counts and a history of injection drug use. Patients developing NHL on cART had an increased risk of death compared with patients who were cART naive at diagnosis. CONCLUSION: In the era of cART two-thirds of patients diagnosed with HIV-related systemic NHL survive for longer than 1 year after diagnosis. Survival is poorer in patients diagnosed with primary brain lymphoma. More advanced immunodeficiency is the dominant prognostic factor for mortality in patients with HIV-related NHL.

[Evaluation of the surveillance system for human immunodeficiency virus infections of Navarra, Spain, 1985-2003]. / Evaluación del sistema de información de Navarra sobre diagnósticos de infección por el VIH, 1985-2003.

BACKGROUND: Navarra has an information system of HIV diagnoses working since the beginning of the epidemic up to the present day. This study aims at describing and evaluating this system, focusing on its sensitivity. METHODS: The updated guidelines for evaluating public health surveillance systems from the CDC were used to describe the purpose and operation of the system and to analyse its attributes for the period 1985-2003. For the evaluation of the sensitivity the regional database of antiretrovirals distribution was used. RESULTS: The HIV surveillance system of Navarra is confidential and name-based, and includes all HIV-infection cases diagnosed each year. The information sources of the system are: (a) all the laboratories in the public health system that perform the western blot test, and (b) hospital discharge registries. The system covers the entire population of Navarre (584,734 inhabitants). It uses the HIV case definition proposed by the European Centre for the Epidemiological Monitoring of AIDS. The system is well-accepted by the community and by all the stakeholders, including those providing data. By the end of 2003 it included 2302 HIV cases, and 98.8% of all patients who had ever received antiretrovirals in Navarra. CONCLUSIONS: The HIV information system of Navarra is simple, useful, well-accepted and highly sensitive. The information about antiretroviral distribution was useful for this evaluation.

El objetivo de este trabajo es describir y evaluar su funcionamiento y sus atributos, haciendo énfasis en el estudio de su sensibilidad. Métodos: Siguiendo las directrices para la Evaluación de Sistemas de Vigilancia en Salud Pública de los Centros para el Control y Prevención de Enfermedades de Atlanta, describimos el sistema de información sobre diagnósticos de infección por VIH de Navarra (el sistema) y analizamos sus atributos cualitativos y cuantitativos entre 1985 y 2003. Para valorar la sensibilidad se utilizó como referencia el registro de dispensación de antirretrovirales de los hospitales de Navarra. Resultados: El sistema de información sobre diagnósticos de infección por VIH de Navarra es nominal y confidencial, e incluye los casos nuevos diagnosticados cada año. Sus fuentes de información son todos los laboratorios que realizan la prueba de confirmación de Western blot en el sistema público, y el registro de altas hospitalarias de la Comunidad Autónoma. Cubre a toda la población de Navarra (584.734 habitantes), y utiliza la definición de caso de infección por VIH del Centro Europeo para la Vigilancia Epidemiológica del VIH y el sida. Es un sistema bien aceptado por la comunidad y por los responsables de suministrar los datos. Hasta diciembre de 2003 se habían incluido 2.302 casos, incluyendo al 98,8% de los pacientes que reciben o han recibido antirretrovirales en Navarra. Conclusiones: Este sistema de información es sencillo, útil, bien aceptado y altamente sensible. La información sobre uso de antirretrovirales ha sido de utilidad para su evaluación

[Spanish cohort of naïve HIV-infected patients (CoRIS): rationale, organization and initial results]. / Cohorte RIS de pacientes con infección por VIH sin tratamiento antirretroviral previo (CoRIS): metodología y primeros resultados.

OBJECTIVE: To describe the methodology and baseline results of the Spanish cohort of naïve HIV-infected patients included in the Research Network on HIV/AIDS (CoRIS). METHODS: CoRIS is a multicenter, hospital-based prospective cohort of HIV sero-prevalent, retroviral-naïve subjects, over 13 years old, and seen at 17 hospitals in 8 of the 17 Autonomous Regions in Spain from January 2004 to October 2005. The socio-demographic characteristics, as well as epidemiological, clinical, laboratory and treatment data were recorded, and biological samples were collected at baseline and during follow-up. RESULTS: A total of 1,591 subjects have been included in CoRIS; 24% are women, median age at cohort entry is 36 years, and 74% were diagnosed during 2004 or 2005. Twenty-seven percent came from countries other than Spain, mainly Latin-America (16%) and sub-Saharan Africa (5%). Thirty-two percent had completed secondary education and 16% university studies. The most frequent categories of transmission were men having sex with men (37%) and heterosexual sex (36%); only 21% were injection drug users. At cohort entry, median CD4 count was 317 cells/mm 3 and median viral load was 52,300 copies/mL; 18% were diagnosed with AIDS. Main AIDS-defining illnesses were Pneumocystis jiroveci pneumonia (6.1%), esophageal candidiasis (3.3%) and tuberculosis (extrapulmonary, 3.0% and pulmonary 2.7%). There were 35 deaths (2.2%). Thirty-three percent of patients gave a baseline sample to the BioBank. CONCLUSIONS: CoRIS offers relevant information about the current epidemiological profile of HIV infection in Spain, where sexual transmission has become predominant. The type and amount of information obtained from clinical and epidemiological data collection together with biological samples demonstrate the viability of the project, which offers many possibilities for future research.

Cohorte RIS de pacientes con infección por VIH sin tratamiento antirretroviral previo (CoRIS): metodología y primeros resultados / Spanish cohort of naïve HIV-infected patients (CoRIS): Rationale, organization and initial results

At cohort entry, median CD4 count was 317 cells/mm 3 and median viral load was 52,300 copies/mL; 18% were diagnosed with AIDS. Main AIDS-defining illnesses were Pneumocystis jiroveci pneumonia (6.1%), esophageal candidiasis (3.3%) and tuberculosis (extrapulmonary, 3.0% and pulmonary 2.7%). There were 35 deaths (2.2%). Thirty-three percent of patients gave a baseline sample to the BioBank. Conclusions. CoRIS offers relevant information about the current epidemiological profile of HIV infection in Spain, where sexual transmission has become predominant. The type and amount of information obtained from clinical and epidemiological data collection together with biological samples demonstrate the viability of the project, which offers many possibilities for future research (AU)
