Journal ArticleDOI

Jorge F. Vázquez-Castellanos,Sergio Serrano-Villar,Amparo Latorre,Alejandro Artacho,María Loreto Ferrús,Nadia Madrid,A. Vallejo,Talia Sainz,Javier Martínez-Botas,Sara Ferrando-Martinez,Mar Vera,Fernando Dronda,Manuel Leal,J del Romero,Santiago Moreno,Vicente Estrada,María José Gosalbes,Andrés Moya +17 more
TL;DR: Systemic markers of innate and adaptive immunity in a cohort of HIV-infected individuals on successful antiretroviral therapy without comorbidities and in healthy non-HIV- infected subjects are determined.
Journal ArticleDOI
Mycosis fungoides and Sezary syndrome are not associated with HTLV-I infection: an international study.
Ali Bazarbachi,Vincent Soriano,R Pawson,A. Vallejo,T. Moudgil,Estela Matutes,J. Peries,Arturo Molina,Thomas F. Schulz,Daniel Catovsky,P. S. Gill +10 more
TL;DR: Molecular analyses were performed on 215 DNA samples by PCR amplification using HTLV‐I and ‐II gag, pol, env, pX and LTR specific primers, and Reverse transcriptase (RT) assay was performed in 26 cases using an RT‐PCR‐based method of high sensitivity.
Journal ArticleDOI
Changes in the rate of genotypic resistance to antiretroviral drugs in Spain.
Oscar Gallego,Lidia Ruiz,A. Vallejo,E. Ferrer,Amalia Rubio,Bonaventura Clotet,Manuel Leal,Vincent Soriano +7 more
TL;DR: Genotypic resistance to antiretroviral drugs was examined in 684 individuals attending 18 outpatient clinics distributed across Spain in June 2000, finding the prevalence of resistance to nucleosides has declined significantly and resistance among naive chronic HIV carriers has increased.
Journal ArticleDOI
Thymic volume is associated independently with the magnitude of short- and long-term repopulation of CD4+ T cells in HIV-infected adults after highly active antiretroviral therapy (HAART)
Ezequiel Ruiz-Mateos,Amalia Rubio,A. Vallejo,R. de la Rosa,Armando Sánchez-Quijano,Eduardo Lissen,Miguel C. Leal +6 more
TL;DR: Baseline thymic volume was associated independently with the magnitude of short‐ and long‐term recovery of CD4+ T cells after HAART, despite the patients’ viral phenotype, which could have important clinical implications not only in HIV‐infected patients, but also in other scenarios of T cell depletion such as bone marrow transplantation and chemotherapy.
Journal ArticleDOI
Rate of Virological Treatment Failure and Frequencies of Drug Resistance Genotypes among Human Immunodeficiency Virus-Positive Subjects on Antiretroviral Therapy in Spain
TL;DR: The findings suggest that drug resistance mutations are very prevalent among subjects who have experienced several treatment failures, and facilitating the arrival of compounds belonging to new drug classes should be considered a priority.
