RESUMO

Fundamento: Existen pocos datos sobre la eficacia de etravirina (ETV) en la práctica clínica. Métodos Estudio observacional retrospectivo para evaluar su uso, su eficacia y su tolerabilidad. Resultados Los principales motivos de uso de ETV en 151 pacientes pretratrados fueron toxicidad y fracaso virológico. La tolerancia fue buena, y tras 16 meses, el 76,16% tienen carga viral indetectable. Los pacientes con carga viral detectable al inicio tuvieron mayor riesgo de fracaso (31,7% vs 18%; p = 0,05).Conclusiones ETV puede considerarse un fármaco seguro, eficaz y duradero (AU)


Background: There are limited data on etravirine (ETV) use in routine clinical practice. Methods: The reasons, efficacy and tolerability of its use are retrospectively reviewed. Results: Overall, 151 patients started a regimen containing ETV. The main reasons for prescription were toxicity and virological failure. After a median follow-up of 16 months 76.2% of the patients had an undetectable viral load. Patients with detectable HIV-RNA at baseline had a greater risk of failure (31.7% vs18%; P = .05).Conclusion: ETV is safe, effective and durable (AU)

RESUMO

BACKGROUND AND OBJECTIVE: Since the introduction of highly active antiretroviral therapy (HAART), the natural history of HIV infection has been altered by an increasing survival. Following this, neoplastic diseases have become more common in HIV positive patients. The purpose of this study was to describe the types of tumor, clinical features and prognosis of HIV infected patients with malignant diseases. PATIENTES AND METHODS: A descriptive study of epidemiological and clinical features was undertaken at Hospital Carlos III, in Madrid. Information was collected on age, sex, risk factors for HIV, HBV/HCV coinfection, malignancies, diagnosis of AIDS, viral load and CD4 cell counts at diagnosis, antiretroviral therapy and mortality. A total of 139 HIV-infected patients were identified who had at least one malignancy. Statistical analysis was performed using SPSS 15.0 package. RESULTS: Types of malignancy were Kaposi's Sarcoma (n=43, 30.9%); non-Hodgkin lymphoma (n=42, 30.2%); gynecologic malignancy (n=16, 11.5%); Hodgkin's disease (n=15, 10.8%); hepatocellular carcinoma (n=7, 5%) and others (n=16, 11.5%). Mean age at diagnosis was 40 years (IC 95% 38.51-1.50). Male/female ratio was 3.63. Patients with HBV or HCV coinfection were 1.4% and 35.3% respectively. Risk factor for HIV was MSM (n=64;46%), IDUs (n=48; 34.5%) and heterosexual (n=26; 18.7%). Viral load was undetectable in 27 cases (19.4%); CD4 cell count was<200 cell/mcl in 58 cases (41.7%). There were 77 (55.4%) patients on HAART when cancer was diagnosed. Mean time on HAART was 23.31 months. Ten patients (7.2%) developed a secondary tumor. Twelve years survival was 20%. CONCLUSIONS: Increased survival of HIV-infected patients receiving HAART makes it possible the development of secondary tumors and AIDS- unrelated malignancies, sometimes related to another virus.

RESUMO

Fundamento y objetivos: Desde la introducción del tratamiento antirretroviral de gran actividad (TARGA), la historia natural de la infección por el virus de la inmunodeficiencia humana (VIH) se ha modificado, por lo que ha aumentado la supervivencia. Por esto, el diagnóstico de una enfermedad neoplásica es cada vez más frecuente en estos pacientes. El objetivo de este estudio es describir las características clínicas y el pronóstico de un grupo de pacientes infectados por VIH que desarrollan enfermedades tumorales. Pacientes y método: Se realizó un estudio descriptivo sobre las características clínicas y epidemiológicas en el Hospital Carlos III de Madrid. La información recogida incluía edad, sexo, factores de riesgo para el VIH, coinfección con virus de la hepatitis B o C, tumores, diagnóstico de sida, carga viral y recuento de CD4 en el momento del diagnóstico, tratamiento antirretroviral y mortalidad. Se identificaron 139 pacientes infectados por VIH, diagnosticados de, al menos, un tumor. El análisis estadístico se realizó con el programa estadístico SPSS 15.0. Resultados: Los tumores encontrados fueron sarcoma de Kaposi (n=43 [30,9%]), linfoma no hodgkiniano (n=42 [30,2%]), ginecológicos (n=16 [11,5%]), enfermedad de Hodgkin (n=15 [10,8%]), carcinoma hepatocelular (n=7 [5%]) y otros (n=16 [11,5%]). La edad media al diagnóstico fue de 40 atildemos (intervalo de confianza del 95%: 38,51¨C1,50). La proporción varón/mujer fue de 3,63. El porcentaje de pacientes coinfectados por virus de la hepatitis B o C fue del 1,4 y del 35,3%, respectivamente. Las conductas de riesgo más frecuentes para la adquisición del VIH fueron las relaciones homosexuales (n=64 [46%]), la drogadicción parenteral (n=48 [34,5%]) y las relaciones heterosexuales (n=26 [18,7%]). La carga viral era indetectable en 27 casos (19,4%); el recuento de CD4 era menor de 200 células/mm3en 58 casos (41,7%) (…) (AU)

RESUMO

BACKGROUND AND OBJECTIVE: To analyse the characteristics and HIV-1 subtype in a group of HIV+ hospitalised immigrants in our Infectious Diseases Unit. PATIENTS AND METHOD: Clinical reports of 78 immigrants HIV+ were reviewed. HIV-1 subtyping was carried out examining the protease and transcriptase genes by phylogenetic analysis. Statistical study was done by SPSS 11.0 program. RESULTS: 57% of patients come from sub-Saharian Africa. Mainly they had been infected by heterosexual contact. HIV was diagnosed at the hospitalisation time in 35 cases. Only 28% were receiving highly active antiretroviral therapy and 48,7% had CD4+ cells less than 200/microl. The more frequent diagnosed diseases were: tuberculosis (20.5%), candidiasis (24.4%), bacterial pneumonia (19.2%) and malaria (21.8%). HIV-1 subtype B was isolated in 26 patients, none Africans. Twenty nine individuals (52.8%) were infected with HIV-1 non-B subtypes. Relationship between HIV-1 subtype, immunodepression, diagnosed diseases and origin countries was not found apart from malaria. CONCLUSIONS: Most HIV-1 infected immigrants are from Africa, being predominantly infected with HIV-1 non-B subtypes. No relationship between HIV subtype and diagnosed diseases was found.

RESUMO

Fundamento y objetivo: Analizar las características y el subtipo del virus de la inmunodeficiencia humana tipo 1 (VIH-1) en un grupo de inmigrantes seropositivos que ingresaron en nuestro Servicio de Enfermedades Infecciosas. Pacientes y método: Se revisaron los informes de alta de 78 inmigrantes infectados por el VIH. La caracterización del subtipo genético de las variantes del VIH-1 que los infectaron se realizó por análisis filogenético de los genes de la proteasa y de la retrotranscriptasa en el 70,5% de ellos. Para el estudio estadístico se utilizó el programa SPSS, versión 11.0. Resultados: El 57% de los pacientes procedían del África subsahariana, y la transmisión heterosexual fue la vía más frecuente de contagio. La infección por el VIH se diagnosticó en el momento del ingreso en 35 casos. Sólo el 28% recibía tratamiento antirretroviral de gran actividad y un 48,7% tenía menos de 200 linfocitos CD4/µl. Las enfermedades más frecuentes fueron: tuberculosis (20,5%), candidiasis (24,4%), neumonía bacteriana (19,2%) y paludismo (21,8%). El subtipo B del VIH-1 se aisló en 26 de los 78 pacientes, ninguno africano. Se encontraron subtipos diferentes del B en 29 casos (52,8%). No hubo relación entre el subtipo genético del VIH-1, la inmunodepresión, las enfermedades diagnosticadas y el país de origen, excepto en el caso del paludismo. Conclusiones: La mayoría de los inmigrantes con infección por el VIH ingresados en nuestro centro son africanos y en su mayor parte están infectados por subtipos del VIH-1 diferentes del B. No se observó relación entre el subtipo genético y las enfermedades diagnosticadas

RESUMO

Fundamento: En pacientes positivos para el virus de la inmunodeficiencia humana (VIH) se han descrito casos de hipertensión arterial pulmonar y cor pulmonale con hallazgos similares a los observados en la hipertensión arterial pulmonar primaria. Población y métodos: Se analizaron retrospectivamente 14 enfermos positivos para el VIH con datos ecocardiográficos de hipertensión arterial pulmonar diagnosticados durante 9 años (1991-1999). Resultados: El tiempo medio hasta el diagnóstico fue de 4 meses (límites, 1 semana-1 año). La hipertensión arterial pulmonar se consideró leve en 3 casos (23 por ciento), moderada en siete (54 por ciento) y grave en cuatro, con un valor medio del gradiente VD-AD de 57,96 mmHg (límites, 35-87). Se realizó terapia convencional en 10 casos, con progresión de la enfermedad en cinco. En éstos se empleó carvedilol con respuesta favorable en cuatro. Tres enfermos no requirieron tratamiento farmacológico. La evolución a largo plazo fue buena con mejoría clínica y ecocardiográfica en 11 casos (78 por ciento). El tiempo medio de seguimiento fue de 2 años (límites, 1-8 años) y fallecieron 3 pacientes (22 por ciento). Conclusiones: La hipertensión arterial pulmonar en los pacientes con infección por el VIH suele ser de grado moderado-grave y, sin un alto índice de sospecha, se produce un acusado retraso en el diagnóstico. El carvedilol podría ser una buena alternativa terapéutica en los casos de hipertensión arterial pulmonar refractaria a otros tratamientos. (AU)
