RESUMO
INTRODUCTION: Anti-retroviral therapy (ART) in HIV patients has shown reduction in morbidity and mortality, and decrease in contagious risk. International recommendations include early initiation of ART, irrespectively of CD4 cell count. OBJECTIVE: To describe the impact of ART initiation in CD4 cell count and viral load at the end of the first year of HIV treatment, for patients who entered the program at 2013 and 2015. METHODOLOGY: Descriptive study. The sample comprehends all patients who started their ART treatment in the indicated years, at HCVB. RESULTS: 78 and 100 patients initiated ART treatment in 2013 and 2015, respectively. In 2013, 48 out of 78 patients (61.5%), and in 2015, 55 (55%) patients started therapy with CD4 > 200 cell/mm3. The follow-up in the first group resulted on 43 (55%) patients with an undetectable CV at the end of first year of treatment, meanwhile in the second group 72% achieved this target (p = 0.001). CONCLUSIONS: Early ART initiation increased the proportion of patients with undetectable CV. However, we must improve strategies to optimize results.

BACKGROUND: Cryptococcosis is a severe opportunistic mycotic infection, caused mainly by Cryptococcus neoformans. It can present as meningitis, pneumonia or cryptococcemia. AIM: To characterize patients with Cryptococcus infection between January 1°, 2013 and June 30, 2016, in Hospital Carlos van Buren, Valparaíso, Chile. METHODS: We identified retrospectively those cultures with Cryptococcus sp. growth, and then obtained their clinical files which were analyzed by two independent reviewers. RESULTS: We were able to obtain data from 13 of 15 patients who presented with Cryptococcus neoformans infection. Out of all, 11 (84.6%) were males, with a median age of 35 years old. 11 (84,6%) were HIV positive, 1 (7,7%) had chronic lymphocytic leukemia, and 1 (7,7%) refered alcohol abuse. Out of the 15 episodes, 9 (60%) had meningeal infection; 5 (33.3%) were cryptococcemia without meningeal involvement and 1 (6.6%) presented as a pulmonary infection. Eight patients were deceased at one year follow up. CONCLUSIONS: Cryptococcus sp. infection must be suspected in patients with cellular immunodeficiencies. Meningeal involvement is the most frequent form of clinical presentation. It still has a high mortality rate.

Resumen Introducción: La criptococcosis es una infección micótica oportunista grave, Cryptococcus neoformans es la principal especie de importancia médica, pudiendo manifestarse como meningitis, neumonía o criptococcemia. Objetivo: Caracterizar a los pacientes con infección por Cryptococcus sp. entre el 01/01/13 y 30/06/16, en el HCVB. Materiales y Métodos: Se identificaron los cultivos con desarrollo de Cryptococcus sp., y a partir de éstos se obtuvo los registros de los pacientes, los que fueron analizados por dos revisores independientes. Resultados: Se recopiló la información de 13 pacientes, que presentaron 15 casos de infección por C. neoformans. De los 13 pacientes, 11 (84,6%) eran de sexo masculino, con una mediana de edad de 35 años. 11 pacientes (84,6%) padecían infección por VIH, uno (7,7%) tenía el antecedente de leucemia linfática crónica, y uno (7,7%) de etilismo crónico. De los 15 casos, nueve (60%) presentaron infección meníngea; cinco (33,3%) presentaron criptococcemia sin compromiso del LCR; y uno (6,6%) presentó infección pulmonar. De los 13 pacientes, ocho (53,3%) se encontraban fallecidos al año de seguimiento. Conclusiones: La infección por Cryptococcus sp. es una patología que debe ser sospechada en pacientes con inmunodeficiencia de predominio celular. La infección meníngea fue la forma más frecuente de presentación. Persiste presentando una elevada mortalidad.

Resumen Introducción: La terapia anti-retroviral (TARV) en pacientes con infección por VIH ha causado una disminución de la morbimortalidad y del riesgo de transmisión. Las recomendaciones internacionales actuales sugieren un inicio precoz de TARV, independiente del recuento de linfocitos T CD4. Objetivo: Describir el impacto del inicio de TARV en el recuento de CD4 y carga viral (CV) al año de tratamiento en pacientes que ingresaron al Programa de VIH del HCVB en los años 2013 y 2015. Métodos: Estudio descriptivo que incluyó a todos los pacientes que iniciaron TARV durante los años mencionados. Resultados: 78 y 100 pacientes iniciaron TARV el año 2013 y 2015; respectivamente. El año 2013, 48 (61,5%) pacientes, y el año 2015, 55 (55%) pacientes iniciaron terapia con un recuento de CD4 > 200 céls/mm3. En el primer grupo, al año de seguimiento, 43 (55%) pacientes tuvieron una CV indetectable; mientras que en el segundo grupo, esta meta se logró en 72% de los casos (p = 0,001). Conclusiones: El inicio temprano de TARV aumentó la proporción de pacientes con CV indetectable. Sin embargo, debemos mejorar las estrategias para optimizar los resultados.

INTRODUCCIÓN: la meningitis bacteriana es una enfermedad infecciosa aguda grave, que por su letalidad y costos en atención de salud genera un alto impacto en Salud Pública. Los agentes causales más frecuentes son Streptococcus pneumoniae, Neisseria meningitidis, Haemophilus influenzae y Listeria monocytogenes, pero poco conocemos de nuestra realidad local. MATERIALES Y MÉTODOS: estudio descriptivo, con revisión de base de datos del laboratorio de microbiología del Hospital Carlos Van Buren, obteniendo datos de los cultivos de líquido céfalo raquídeo de pacientes mayores de 15 años entre marzo de 2013 y noviembre de 2016. RESULTADOS: 128 casos de meningitis bacteriana aguda, de los cuales 17 fueron por los microorganismos objetivos del estudio, siendo el más frecuente S. pneumoniae, clínicamente un 58% se presentó sin signos meníngeos. A 30 días del diagnóstico un 35% había fallecido, la mitad de ellos inició el tratamiento antibiótico pasadas las 24 horas desde su ingreso al hospital. En el 46% la tinción gram no evidenció bacterias. DISCUSIÓN: los microorganismos clásicamente descritos como agentes causales parecen no explicar la totalidad de los cuadros de meningitis bacteriana aguda en la población adulta estudiada, la ausencia de signos meníngeos no permite descartar la sospecha diagnóstica. La mitad de los pacientes fallecidos inició el tratamiento antibiótico pasadas las primeras 24 horas.
INTRODUCTION: bacterial meningitis is a serious acute infectious disease whose lethality and elevated health costs have a serious impact on public health. The most frequent causes are Streptococcus pneumoniae, Neisseria meningitidis, Haemophilus influenza and Listeria monocytogenes, but we know little of the local situation. MATERIALS AND METHODS: A descriptive study reviewing Carlos van Buren Hospital´s microbiology laboratory data base, and obtaining the details of cerebrospinal fluid cultures of patients over the age of 15 between March 2013 and November 2016. RESULTS: 128 cases of acute bacterial meningitis of which 17% were caused by the micro-organisms of study, the most frequent being Streptococcus pneumoniae. 58% of patients had no meningeal signs. At 30 days from diagnosis 35% had died, half of these having started antibiotic treatment over 24 hours after admission. 46% of the Gram stains showed no bacteria. DISCUSSION: the classical infectious agents do not appear to account for the totality of acute bacterial meningitis in the population studied. The absence of meningeal signs should not rule out the diagnosis. Half of the patients who died started antibiotic treatment after the first 24 hours.

Background: Chilean AIDS Cohort is the oldest and extensive in Latin America and one of most numerous and with longer follow up time to international level. Records information from 14,873 patients out of approximately 22,000 in antiretroviral therapy in the public system and its results have allowed to know the national reality and have contributed to the adoption of public policies. Aim: To describe the demographic, clinical and immunological characteristics of patients who have started ART in Chile and its evolution over the past 15 years. Patients and Methods: The cases were stratified by five-year periods: 2001-2005, 2006-2010 and 2011-2015. The data analysis included calculating proportions, their respective confidence intervals 95% and X² test for significance analysis was applied. Results: 17.4% of patients starting ART are women and the proportion has remained relatively constant. The highest proportion of new HIV cases are 30 and 39 years old, nevertheless the layer of 15-29 years demonstrates a significant increase from 21.7 to 36.4% in 2011-2015 especially in men. 12.1% of new cases are older than 50 years old with a stable trend over time; however, women over 50 have increased from 11.0 to 15.6%. Antiretroviral therapy initiation with CD4+ T lymphocytes less than 200 cells/mm³ has decreased from 79.7 to 42.4% and in stage C from 45.4 to 22.6%. Late presentation to antiretroviral therapy is higher in men but this gap has narrowed in the last five years. Pneumocystis jiroveci, wasting syndrome, tuberculosis, Kaposi’s sarcoma and esophageal candidiasis are the most common opportunistic diseases without significant changes in the three-year periods analyzed. In the last five years, 15.5% of opportunistic diseases occurs in patients with CD4+ TL > 200 cells/mm3. Discussion: Despite the limitations of observational studies present report describes the characteristics and evolution of the epidemics in Chile in the last 15 years. The infection occurs at younger ages in men, whereas in women there is an increase over 50 years old. Despite advances in treatment access have reduced late presentation to therapy, important challenges remain to achieve more timely initiation of antiretroviral therapy in accordance with WHO 90-90-90 goals.
Introducción: La Cohorte Chilena de SIDA es la más antigua y extensa de Latinoamérica y una de las más numerosas y con mayor tiempo de seguimiento a nivel internacional. Registra información de 14.873 pacientes de los aproximadamente 22.000 en TARV en el sistema público y sus resultados han permitido conocer la realidad nacional y han contribuido a la adopción de políticas públicas. El objetivo de este estudio es describir las características demográficas, clínicas e inmunológicas de los pacientes que han comenzado TARV en Chile y su evolución en los últimos 15 años. Pacientes y Métodos: Los casos fueron estratificados por quinquenios: 2001-2005, 2006-2010 y 2011-2015. El análisis de los datos incluyó el cálculo de proporciones, sus respectivos intervalos de confianza 95% y se aplicó test de X² para análisis de significación. Resultados: El 17,4% de los casos que inician TARV corresponde a mujeres y la proporción se ha mantenido relativamente constante. Por edad, destaca el grupo de adultos entre 30 y 39 años aunque el estrato de 15-29 años evidencia un importante aumento desde 21,7 a 36,4% en 2011-2015, especialmente en hombres. Un 12,1% del total de los inicios de TARV son mayores de 50 años con una tendencia estable en el tiempo; sin embargo, las mujeres mayores de 50 años han aumentado de 11,0 a 15,6%. El inicio de TARV con LT CD4 menor de 200 céls/mm³ ha disminuido desde 79,7 a 42,4% y en etapa C desde 45,4 a 22,6%. La presentación tardía a TARV es mayor en hombres pero esta diferencia se ha reducido en el último quinquenio. Neumonía por Pneumocystis jiroveci, síndrome consuntivo, tuberculosis, sarcoma de Kaposi y candidiasis esofágica son las enfermedades oportunistas más frecuentes sin cambios significativos en los tres quinquenios analizados. En el último quinquenio, 15,5% de las enfermedades oportunistas se presenta en pacientes con LT CD4 > 200 céls/mm³. Discusión: Pese a las limitaciones de los estudios observacionales el presente reporte describe las características y evolución de la epidemia en Chile en los últimos 15 años. La infección se presenta a edades más jóvenes en hombres, mientras que en mujeres hay un aumento en mayores de 50 años. Pese a los avances en acceso a tratamiento que han permitido reducir la presentación a tardía a terapia, aún persisten importantes desafíos para alcanzar un inicio de TARV más oportuno, en concordancia con las metas 90-90-90 de OMS.

BACKGROUND: Thyroid dysfunction is common among patients infected with human immunodeficiency virus (HIV). It presents in different forms and has a multifactorial etiology. AIM: To determine the prevalence and features of thyroid dysfunction among patients infected with HIV. MATERIAL AND METHODS: A cross-sectional study of 127 patients infected with HIV aged 19 to 75 years (85% males). Patients with previous diagnoses of endocrine diseases and pregnant women were excluded. Participants responded a questionnaire about symptoms and the evolution of HIV infection. A blood sample was obtained to measure thyroid stimulating hormone, free thyroxin, viral load and CD4 count. RESULTS: Hypothyroidism was found 13 cases, hyperthyroidism in one case and hypothyroxinemia in eight cases. No difference in symptoms was found between patients with or without thyroid dysfunction. No significant differences were observed in CD4 count or the prevalence of co-infection with Hepatitis B virus among patients with thyroid dysfunction. No association between antiretroviral agents and thyroid dysfunction was observed. CONCLUSIONS: The thyroid abnormalities found in this group of HIV infected patients were usually asymptomatic. It may be advisable to systematically assess thyroid function in HIV infected patients.

INTRODUCTION: Invasive fungal diseases (IFD) by filamentous fungi are a common cause of morbidity and mortality in immunocompromised patients, especially those with myeloid leukemia. In 2011 a protocol for the rapid diagnosis of IFD by filamentous fungi was implemented in Valparaiso Region. OBJECTIVES: To describe cases of IFD by filamentous fungi of the Valparaíso Region, since the implementation of rapid diagnosis and to compare results with the period 2004-2009. MATERIALS AND METHOD: Descriptive and prospective study conducted in two public hospitals: Carlos van Buren at Valparaiso and Gustavo Fricke at Viña del Mar. We selected patients with a diagnosis of filamentous fungal diseases considering the EORTC/MSG criteria. Demographics, underlying diseases, risk factors for EFI, galactomannan (GM) results in blood and bronchoalveolar lavage, cultures and biopsies, treatment and overall lethality rates at 30 days were registered. RESULTS: Eighteen patients were detected, 6 with proven and 12 probable IFD. Nine were diagnosed by GM, 8 by culture and two with both methods. In cases which the agent (9/18) was isolated from Rhizopus oryzae was the most frequent. When comparing overall lethality with the period 2004-2009, there was a reduction of 47.8%, which was statistically significant. CONCLUSIONS: Compared to data previously published in the region, demographic and comorbidities of patients with IFD caused by filamentous fungi are similar, however the currently rapid diagnosis protocol has improved survival of patients and lethality experienced overall decrease.
