Factores asociados con la no realizacion de la prueba de la tuberculina en una cohorte de pacientes VIH positivos / Factors related to non-prescription of tuberculin skin testing in a cohort of HIV-infected people

Introduccion Dada la asociacion entre tuberculosis (TB) e infeccion por VIH, la realizacion del Mantoux esta indicada en todo paciente infectado con VIH. Este articulo analiza la frecuencia de no realizacion de la prueba de la tuberculina y sus factores asociados en una cohorte de infectados con VIH. Pacientes y metodos Entre 2000-C2002 se identifico en 10 hospitales a todos los pacientes infectados con VIH y no seguidos previamente, de forma regular, en consultas especificas. Se recogio informacion de la historia clinica sobre realizacion del Mantoux y otras variables. Se calculo el porcentaje de no realizacion del Mantoux y los factores asociados mediante la utilizacion como medida de asociacion de la odds ratio (OR) y su intervalo de confianza (IC) del 95%. Para el analisis multivariante se ajusto un modelo de regresion logistica. Resultados Mil doscientos cuarenta y dos pacientes cumplieron criterios de inclusion y a 185 pacientes no se les realizo el Mantoux (el 17,6% de aquellos en los que estaba indicado). La probabilidad de no realizacion del Mantoux fue mayor en usuarios de drogas (OR: 2,6; IC del 95%: 1,1¨C6,5) y menor entre los desempleados (OR: 0,6; IC del 95%: 0,3¨C1,0), aquellos con mas de 200 CD4 (CD4 200¨C499: OR: 0,5; IC del 95%: 0,3¨C0,9; CD4 ¡Ý500: OR: 0,3; IC del 95%: 0,2¨C0,6) y los contactos con enfermos tuberculosos (OR: 0,2; IC del 95%: 0,1¨C0,5).ConclusionesEl porcentaje de no realizacion del Mantoux es bastante elevado. La no realizacion del Mantoux parece asociarse con las expectativas del medico, tanto sobre el resultado de la prueba como sobre la correcta cumplimentacion del tratamiento preventivo anti-TB por el paciente ( AU)

Introduction Tuberculin skin testing (TST) for tuberculosis (TB) is recommended for all patients with HIV infection because of the known relationship between these two conditions. In this report we analyze the incidence and variables associated with non-prescription of TST in a cohort of HIV-infected people. Patients and methods Longitudinal study conducted between 2000 and 2002 at 10 HIV hospital-based clinics. All HIV-infected patients who had not been regularly followed-up previously in dedicated clinics were identified. Data about TST and other variables related to TB were obtained from the clinical records. We calculated the percentage of patients who did not undergo TST and the associated factors, using odds ratios (ORs) and the 95% CI to investigate associations. A multivariate logistic regression analysis was performed. Results A total of 1242 patients met the inclusion criteria. TST was not performed in 185 patients (17.6% of those eligible). The fact of being an intravenous drug abuser was associated with a higher probability of TST non-prescription (OR: 2.6, 95% CI 1.1¨C6.5), whereas being unemployed (OR: 0.6, 95% CI 0.3¨C1.0), having a CD4 cell count >200 (CD4 200¨C499: OR 0.5, 95% CI 0.3¨C0.9. CD4¡Ý500: OR 0.3, 95% CI 0.2¨C0.6), and contact with persons with TB (OR 0.2, 95% CI 0.1¨C0.5) were associated with a lower probability. ConclusionsIn this study, the percentage of TST non-prescription was quite high. The results suggest that TST non-prescription in this population is related to the clinicians¡¯ expectations regarding the results of the test and the patients¡¯ adherence to treatment for latent TB infection(AU)

INTRODUCTION: Tuberculin skin testing (TST) for tuberculosis (TB) is recommended for all patients with HIV infection because of the known relationship between these two conditions. In this report we analyze the incidence and variables associated with non-prescription of TST in a cohort of HIV-infected people. PATIENTS AND METHODS: Longitudinal study conducted between 2000 and 2002 at 10 HIV hospital-based clinics. All HIV-infected patients who had not been regularly followed-up previously in dedicated clinics were identified. Data about TST and other variables related to TB were obtained from the clinical records.

The fact of being an intravenous drug abuser was associated with a higher probability of TST non-prescription (OR: 2.6, 95% CI 1.1-6.5), whereas being unemployed (OR: 0.6, 95% CI 0.3-1.0), having a CD4 cell count >200 (CD4 200-499: OR 0.5, 95% CI 0.3-0.9. CD4> or =500: OR 0.3, 95% CI 0.2-0.6), and contact with persons with TB (OR 0.2, 95% CI 0.1-0.5) were associated with a lower probability. CONCLUSIONS: In this study, the percentage of TST non-prescription was quite high. The results suggest that TST non-prescription in this population is related to the clinicians' expectations regarding the results of the test and the patients' adherence to treatment for latent TB infection.

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)

Treatment-limiting toxicities associated withnucleoside analogue reverse transcriptase inhibitor therapy: A prospective, observational study.

BACKGROUND: The Recover Study is an ongoing, prospective study designed 10 to assess toxicity associated with the use of nucleoside analogue reverse transcriptase inhibitors (NRTIs) (stavudine, zidovudine, lamivudine, didanosine, abacavir) in HIV-1-infected patients receiving highly active antiretroviral therapy (HAART) in routine clinical practice. This project is being conducted at 120 HIV units at teaching hospitals across Spain. OBJECTIVE: The aim of this study was to identify the most common treatment-limiting 10 moderate to severe clinical and laboratory adverse effects (AEs), and the individual NRTIs involved in the development of these effects, in HIV-1-infected patients receiving HAART who discontinued use of an NRTI in the Recover Study. METHODS: Patients eligible for participation in the Recover Study are aged10 ≥18 years; have virologically documented HIV-1 infection; have sustained viral suppression (viral load <200 cells/mL or stable, heavily experienced [ie, have received ≥3 antiretroviral regimens] patients with viral load <5000 cells/mL) for ≥6 months; are receiving HAART; are undergoing active follow-up; and have developed 2:1 NRTI-associated AE that, in the opinion of a study investigator and under the conditions of routine clinical practice, justified discontinuation of treatment with the offending drug (principal AE/offending NRTI). The present study included patients recruited for the Recover Study between September 2002 and May 2003. RESULTS: A total of 1391 patients were enrolled (966 men, 425 women; mean 1 age, 42 years [range, 18-67 years]). Five hundred six patients (36.4%) had been diagnosed with AIDS. The mean duration of treatment with the offending NRTI was 74 months (range, 6-156 months). Seven hundred nine patients (51.0%) were receiving fourth-line (or more) therapy. Eight hundred twenty-one patients (59.0%) were receiving nonnucleoside analogues, and 552 patients (39.7%), protease inhibitors, as components of their HAART regimens. The NRTIs with the highest discontinuation rates were stavudine (914 patients [65.7%]) and zidovudine (177 [12.7%]). The most frequent NRTI-related AEs were lipoatrophy (550 patients [39.5%]) and peripheral neuropathy (170 [12.2%]). Lipoatrophy was most commonly associated with stavudine (480/550 cases [87.3%]); periph eral neuropathy, with stavudine and didanosine (107/170 [62.9%] and 48/170 [28.2%] cases, respectively); and anemia, with zidovudine (70/77 cases [90.9%]). CONCLUSIONS: The results of this study in patients with HIV-1 recruited in the10 Recover Study and undergoing HAART suggest that long-term treatment with NRTIs is associated with AEs (lipoatrophy, peripheral neuropathy, and lipodystrophy), with morphologic disorders (lipoatrophy, lipodystrophy) being the most common AEs leading to discontinuation. Minimizing these AEs by switching to an NRTI not associated with these AEs (eg, tenofovir) would contribute to adherence and hence efficacy of long-term HAART.
