RESUMO
INTRODUCTION: Health care-associated infections (HAIs) contribute to morbidity and mortality and to the dissemination of multidrug-resistant organisms. Children admitted to the intensive care unit undergo invasive procedures that increase their risk of developing HAIs and sepsis. The aim of the study was to analyse factors associated with mortality due to sepsis arising from HAIs. PATIENTS AND METHODS: We conducted a case-control study in a 7-bed multipurpose paediatric intensive care unit in a tertiary care teaching hospital. The sample consisted of 90 children admitted between January 2014 and December 2018. The case group consisted of patients who died from sepsis associated with the main health care-associated infections; the control group consisted of patients who survived sepsis associated with the same infections. RESULTS: Death was associated with age less than or equal to 12 months, presence of comorbidity, congenital disease, recurrent ventilator-associated pneumonia and septic shock. In the multiple regression analysis, heart disease (OR, 12.48; CI 2.55-60.93; P = .002), infection by carbapenem-resistant bacteria (OR, 31.51; CI 4.01-247.25; P = .001), cancer (OR, 58.23; CI 4.54-746.27; P = .002), and treatment with adrenaline (OR, 13.14; CI 1.35-128.02; P = .003) continued to be significantly associated with death. CONCLUSIONS: Hospital sepsis secondary to carbapenem-resistant bacteria contributed to a high mortality rate in this cohort. Children with heart disease or neoplasia or who needed vasopressor drugs had poorer outcomes.

Understanding the proportion of SARS-CoV-2 patients with Mycoplasmapneumoniae coinfection is crucial for treating patients suffering from coronavirus disease (COVID-19), help to ensure responsible use of antibiotics and minimize the negative consequences of overuse. In addition, this knowledge could have an impact on empirical antibiotic management guidelines for patients with COVID-19. This systematic review aimed to identify the prevalence of M. pneumoniae in patients with coronavirus disease 2019 (COVID-19). A bibliographic search of studies published in Spanish or English was conducted using the PubMed search engine. Fourteen articles from different continents (America, Asia and Europe) were included, involving a total of 5855 patients in these studies. The mean age of COVID-19 patients with M. pneumoniae was 48 years old (range 1-107), most of whom were male. The detection of laboratory-confirmed M. pneumoniae infection varied between 0 and 33.3%. Most of patients referred fever, cough, and dyspnea, and received empirical antibiotic treatment. Bacterial coinfection was not associated with increased ICU admission and mortality. The prevalence of coinfection showed extremely dissimilar figures according to the population studied and diagnostic criteria. However, it is important to develop Latin American studies, given the heterogeneity observed in the studies conducted in different countries. Standardized definitions should be developed in order to be able to assess the impact of coinfections in patients with a diagnosis of COVID-19.

Desde 2007, el Servicio de Epidemiología e Infectología, ha implementado un programa de transición que busca optimizar la atención de los adolescentes con infección por el HIV durante el paso de la atención pediátrica a la de adultos. Objetivo: Describir las características clínicas, epidemiológicas, virológicas y psicosociales de los adolescentes con infección HIV atendidos en el Programa y analizar el proceso de transición. Materiales y Métodos: Estudio de cohorte retrospectivo. Se incluyeron a los adolescentes, atendidos en el Programa de Transición entre enero de 2019 y diciembre de 2023, en el Hospital Garrahan, con al menos un resultado de CV y CD4+ en ese período. Se obtuvo la información de la historia clínica electrónica y se analizaron variables clínicas, epidemiológicas, virológicas, terapéuticas y psicosociales. Resultados: Se incluyeron 124 pacientes. La vía de transmisión fue vertical en el 92,74% y el estadio clínico e inmunológico era avanzado. En el momento de la transición 77,4% se encontraban con supresión virológica y con recuperación inmunológica. El 55,6% ya realizó la transición a un centro de adultos, 31,4% continúan en el programa, 11,3% se perdieron en el seguimiento y 1,7% fallecieron. Se recopilaron los datos de 31 pacientes transferidos. La mediana de seguimiento fue de 2 años; 25 pacientes (80,6%) continúan en seguimiento. Conclusiones: A pesar de la pandemia de COVID-19, el programa logró la retención de los adolescentes con infección por HIV y una transferencia sostenida en el tiempo. Además de un programa de transición estructurado para garantizar una atención continua y de calidad, es necesario continuar evaluando la evolución postransición (AU)
Since 2007, the Epidemiology and Infectious Diseases Department has implemented a transition program to optimize the care of adolescents with HIV infection during their transition from pediatric to adult care. Objective: To describe the clinical, epidemiological, virological, and psychosocial characteristics of adolescents with HIV infection treated in the program and to analyze the transition process. Materials and Methods: A retrospective cohort study was conducted. Adolescents followed in the Transition Program at Garrahan Hospital between January 2019 and December 2023, with at least one viral load and CD4+ result during that period, were included. Information was obtained from electronic medical records, and clinical, epidemiological, virological, therapeutic, and psychosocial variables were analyzed. Results: A total of 124 patients were included. The route of transmission was vertical in 92.74%, and the clinical and immunologic stage was advanced. At the time of transition, 77.4% were virologically suppressed and had achieved immunologic recovery. Of the patients, 55.6% had already transitioned to an adult center, 31.4% were still in the program, 11.3% were lost to follow-up, and 1.7% died. Data were collected from 31 transferred patients, with a median follow-up of 2 years; 25 patients (80.6%) remain in follow-up. Conclusions: Despite the COVID-19 pandemic, the program successfully retained HIVinfected adolescents and ensured sustained transition over time. In addition to a structured transition program to ensure continuous and quality care, it is necessary to continue evaluating post-transition outcomes (AU)

El parto prematuro (PP) es la principal causa de morbilidad/mortalidad perinatal en el mundo. La infección intrauterina es el origen más frecuente del PP espontáneo (PPE) en un hospital público de Chile. Existe evidencia de que la infección bacteriana ascendente (IBA) produce la infección/inflamación intraamniótica, el PPE y los resultados adversos maternos y perinatales. Esta revisión narrativa incluye revisiones sistemáticas y estudios de cohorte o de caso-control sobre la microbiota y el perfil inmunológico existente en el tracto genital inferior (TGI) de la embarazada propensa a PPE por IBA. Existe consenso en que en la microbiota del TGI de esta gestante hay colonización vaginal con baja abundancia de lactobacilos y/o disminución de su calidad, por diferencias raciales y/o geográficas o genéticas y una desregulación de los mecanismos inmunológicos del TGI. Estas respuestas se presentan con mayor intensidad en pacientes con factores de riesgo del huésped, como diabetes, obesidad, estrés, ansiedad y depresión, originando infecciones recurrentes del TGI, responsables del PPE y de los resultados perinatales. El conocimiento del comportamiento de la microbiota y del sistema inmunitario en estos casos permitirá tener terapias eficaces para prevenir el PPE y la morbilidad/mortalidad neonatal por IBA.
Preterm delivery (PD) is the leading cause of perinatal morbidity/mortality in the world. Intrauterine infection is the most frequent origin of spontaneous PD (SPD) in a public hospital in Chile. There is evidence that vaginal ascending bacterial infection (ABI) causes intra-amniotic infection/inflammation, SPD, and adverse maternal and perinatal outcomes. This narrative review includes systematic reviews and cohort or case-control studies on the microbiota and immunological profile existing in the lower genital tract (LGT) of pregnant women prone to SPD due to ABI. There is consensus that in the LGT microbiota of this pregnant woman there is vaginal colonization with low abundance of Lactobacilli and/or decreased quality, due to racial and/or geographic, or genetic differences and dysregulation of immunological mechanisms of the LGT. These responses occur with greater intensity in patients with host risk factors, such as diabetes, obesity, stress, anxiety, and depression, causing recurrent LGT infections responsible for SPD and perinatal outcomes. Knowledge of the behavior of the microbiota and the immune system in these cases will allow effective therapies to prevent SPD and neonatal morbidity/mortality due to ABI.
RESUMO
INTRODUCTION: Percutaneous nephrostomy tubes (PNT), which are used in some cancer hospitals, are associated with an increase in urinary tract infections (UTI). OBJECTIVE: To determine the impact of a standardized care program on the incidence of UTIs requiring hospitalization (UTI-RH). MATERIAL AND METHODS: Retrospective study that included patients with a first PNT inserted. The incidence, relative risk (RR), costs and outcomes of patients with UTI-RH were compared during the period before (P0) vs. after the intervention (P1). RESULTS: 113 PNTs were inserted during P0, and 74 at P1. During P0, 61 patients (53.9%) experienced 64 UTI-RH events in 22,557 PNT days. At P1, four patients (5.4%) had a UTI-RH in 6,548 PNT days (IRR: 0.21, 95% CI: 0.05-0.57). The RR was 0.09 (95% CI: 0.03-0.25). Monthly cost per day/bed was USD 3,823 at P0 and USD 1,076 at P1, and for antibiotics, it was USD 790 at P0 and USD 123.5 at P1. CONCLUSIONS: This study highlights the importance of a standardized care program for permanent percutaneous devices, since this reduces antibiotic use, hospitalization, and the cost of care.
ANTECEDENTES: Los catéteres de nefrostomía percutánea (CNP) que se utilizan en algunos hospitales oncológicos condicionan un incremento en las infecciones del tracto urinario (ITU). OBJETIVO: Determinar el impacto de un programa estandarizado de atención en la incidencia de ITU que requiere hospitalización (ITU-RH). MATERIAL Y MÉTODOS: Estudio retrospectivo que incluyó pacientes con un primer CNP. Se comparó la incidencia, riesgo relativo (RR), costos y evolución de los pacientes con ITU-RH durante el período previo a la intervención (P0) versus posterior a ella (P1). RESULTADOS: Se instalaron 113 CNP durante P0 y 74 durante P1. Durante P0, 61 pacientes (53.9 %) presentaron 64 episodios de ITU-RH, en 22 557 días de uso de CNP. Durante P1, cuatro pacientes (5.4%) cursaron con ITU-RH en el transcurso de 6548 días de uso del CNP (razón de tasa de incidencia de 0.21, IC 95 % = 0.05-0.57). El RR fue de 0.09 (IC 95 % = 0.03-0.25). El costo mensual por día-cama fue de 3823 USD en P0 y de 1076 USD en P1; el de los antibióticos, de 790 USD en P0 y 123.5 USD en P1. CONCLUSIONES: Este estudio resalta la importancia de un programa estandarizado del cuidado de los dispositivos permanentes, el cual disminuye el uso de antibióticos, la hospitalización y el costo de la atención.

La infección por Neisseria gonorrhoeae (NG) es considerada de alta prioridad en salud pública, por su capacidad para desarrollar resistencia a la mayoría de los antibióticos empleados para tratarla. La presentación anorrectal suele ser asintomática y frecuente en hombres que tienen sexo con hombres (HSH). En Argentina, se recomienda terapia antibiótica dual (ceftriaxona+azitromicina/doxiciclina) como primera línea empírica. Este estudio observacional y retrospectivo se realizó para evaluar el porcentaje de positividad de NG anorrectal, el perfil de sensibilidad a penicilina, tetraciclina, ciprofloxacina, ceftriaxona, cefixima y azitromicina, así como los aspectos clínicos-epidemiológicos de los pacientes atendidos entre 20/10/2015 y 20/03/2020 en consultorios coloproctológicos de un hospital público. Se detectaron 55/436 hisopados rectales positivos para NG (13%). El 95% era HSH y 71%, VIH+. En 18/55 NG fue la única infección. Las co-infecciones más frecuentes: HPV (38%) y C. trachomatis (35%). La sensibilidad a cefalosporinas de espectro extendido (CEE) y a azitromicina fueron 100% y 98%, respectivamente. Se observó la emergencia local de los primeros cinco aislamientos de NG anorrectal con sensibilidad reducida (SR) a CEE, el primer aislamiento con categoría no-sensible a azitromicina y otro con SR a azitromicina concomitantemente con SR a CEE. Aunque el uso de terapia empírica dual sigue siendo adecuado para nuestra institución, se observó la emergencia de aislamientos con SR y NS a las drogas de primera línea, evidenciando la importancia de la vigilancia epidemiológica a nivel local para definir los tratamientos empíricos.
Neisseria gonorrhoeae (NG) infection is considered a high public health priority because of its ability to develop resistance to most of the antibiotics used to treat it.The anorectal presentation is generally asymptomatic and frequent in men who have sex with men (MSM). In Argentina, dual therapy (ceftriaxone+azithromycin/doxycycline) is recommended as first line empiric therapy.This observational and retrospective study was conducted to evaluate the percentage of anorectal NG positivity, the susceptibility profile to penicillin, tetracycline, ciprofloxacin, ceftriaxone, cefixime and azithromycin, as well as the clinical-epidemiological aspects of patients attended between 20/10/2015 and 20/03/2020 in coloproctology of a public hospital.We detected 55/436 positive rectal swabs for NG (13%). 95% were MSM and 71% were PLHIV. In 18/55 NG was the only infection. The most frequent co-infections: HPV (38%) and C. trachomatis (35%).Susceptibility to extended-spectrum cephalosporins (ESCs) and azithromycin was 100% and 98%, respectively. Local emergence of the first five anorectal NG isolates with decreased susceptibility (DS) to ESCs, the first isolate with nonsusceptible category to azithromycin and another with DS to azithromycin concomitantly with DS to ESCs were observed.Although the use of dual empirical therapy continues to be adequate for our institution, the emergence of isolates with DS and NS to first-line drugs was observed, evidencing the importance of epidemiological surveillance at the local level to define empirical treatments

ntroducción: Las infecciones de piel y partes blandas (IPPB) constituyen la tercera causa de consulta en nuestro centro. S.aureus es el agente etiológico más frecuente en este tipo de infecciones y la meticilino resistencia es clínicamente el mecanismo de resistencia más importante. El objetivo de este trabajo fue analizar la prevalencia de los distintos agentes etiológicos en IPPB en pacientes ambulatorios, así como también estudiar su sensibilidad a los antibióticos y resistencias acompañantes más frecuentes. Materiales y métodos: Estudio descriptivo y retrospectivo que incluyó todas las muestras provenientes de IPPB de pacientes ambulatorios desde octubre de 2017 a abril de 2022. Resultados: Se obtuvieron 180 cultivos positivos de muestras provenientes de IPPB durante el periodo estudiado, 12 fueron infecciones polimicrobianas. En total se obtuvieron 307 aislamientos: el microorganismo aislado con mayor frecuencia fue S.aureus (111; 36,2%). Se hallaron 71 SAMR (64%) y 40 SAMS (36%). De los SAMR, 67 (95%) fueron comunitarios (SAMRC) por criterios microbiológicos, y 4 SAMR hospitalarios (5%). De las cepas SAMRC, 44 (66%) no presentaron resistencias acompañantes, 15 (22% ) fueron resistentes a eritromicina, 12 (18%) a gentamicina y 7 (10%) a clindamicina. Conclusiones: El microorganismo más frecuentemente aislado en IPPB en pacientes ambulatorios fue el S.aureus y 67 aislamientos fueron categorizados como SAMRC por lo cual es necesario considerar al SAMRC como un patógeno frecuente. Debido a la baja resistencia hallada para CLI y TMS ambos podrían ser de elección en el tratamiento empírico en las IPPB en pacientes ambulatorios
Background:S. aureus is the main cause of skin and soft tissues infections (SSTIs) in immunocompetent patients. This type of infection is the third cause of medical consultation in our center. Our objective was to evaluate the prevalence of S. aureus, as well as its sensitivity to antimicrobials, isolated from skin and soft tissue samples from outpatients at an interzonal general acute care hospital located in Buenos Aires, Argentina.Methods: Descriptive and retrospective study that included all outpatient SSTIs samples from October 2017 to April 2022.Results: We obtained 215 positive cultures of samples from SSTIs during the study period. Of a total of 276 isolates: the most frequently isolated microorganism wasS. aureus (111; 40.22%). The prevalence of S. aureuswas 51.63%. We found 71 MRSA (63.96%). Of the SAMR strains, 60.56% did not present accompanying resistance, and only 8 isolates (11.27%) showed resistance to clindamycin. All SAMRs remained sensitive to minocycline and trimethoprim-sulfamethoxazole.Conclusions: The most frequently isolated microorganism in SSTIs was S. aureus and 71 isolates were categorized as SAMR, therefore it is necessary to consider SAMR as a frequent pathogen. Due to the low resistance found for CLI and TMS, they should be considered for empirical treatment in SSTIs in outpatients
