ABSTRACT

PURPOSE: To provide information about which pneumococcal vaccine could have greater coverage in Colombia. METHODS: This is a retrospective analysis of patients diagnosed with invasive pneumococcal disease (IPD) between 2015 and 2019 in Bogotá, Colombia. We compared the theoretical serotype coverage of the available anti-pneumococcal vaccines (i.e., PCV-10, PCV-10 SII, PCV-13, PCV-15, PCV-20, PCV-21, PCV24, PPSV-23) and the non-vaccine-covered serotypes stratified by age. RESULTS: 690 IPD cases were included. In children ≤5 y/o, of the approved vaccines PCV-20 showed the most theoretical protection (71.3 % [149/209]), while in adults aged 18-64 y/o was PCV-20 (61.8 % [164/265]), and in those ≥65 y/o was PPSV-23 (58.1 % [100/172]) followed by PCV-20 (55.2 % [95/172]). The non-covered serotypes represented one-third of the cohort (33.9 % [234/690]), being 6C (20.5 % [48/234]), 15A (12.8 % [30/234]), and 23A (11.5 % [27/234]) the most prevalent. CONCLUSION: Introducing PCV-20 for children and PCV-20 along with a PPSV-23 booster in adults may reduce IPD frequency in all ages in Colombia. The inclusion of non-covered serotypes is required for future vaccines.

ABSTRACT

La evaluación del estado ácido base y de la oxigenación de un paciente es fundamental en cualquier escenario clínico, sea en consulta externa, en un servicio de urgencias, hospitalización, en cirugía o en la unidad de cuidado intensivo. El conocimiento de las bases fisiopatológicas es de suma importancia para el entendimiento y adecuada interpretación de estas condiciones. El objetivo de esta revisión es proveer las bases de conocimiento necesarias para el abordaje adecuado de los gases arteriovenosos y proponer un modelo para la compresión e interpretación de estos. Este artículo aborda las bases fisiopatológicas de las alteraciones ácido base, los modelos existentes en su compresión, el modelo propuesto para su abordaje diagnóstico, sus diagnósticos diferenciales, el enfoque de la hipoxemia, la interpretación de los gases arteriovenosos y las variables que se pueden obtener de estos, el enfoque de la acidosis láctica y unos ejemplos del modelo propuesto.


The evaluation of the acid-base status and the oxygenation of a patient is fundamental in any clinical setting, be it in an outpatient clinic, in an emergency service, hospitalization, in surgery or in the intensive care unit. Knowledge of the pathophysiological bases is of the utmost importance for the understanding and adequate interpretation of these conditions. The objective of this review is to provide the necessary knowledge for the adequate understanding of arteriovenous gases and to propose a model for their comprehension and interpretation. This article addresses the pathophysiological bases of acid-base disorders, the existing models in their comprehension, the model proposed for their diagnostic approach, their differential diagnoses, the diagnostic approach to hypoxemia, the interpretation of arteriovenous gases and the variables that can be obtained from them, the diagnostic approach of lactic acidosis and some examples of the proposed model.

ABSTRACT

INTRODUCTION: Lemierre's syndrome refers to the septic thrombophlebitis of the internal jugular vein, secondary to a pharyngeal infection. Although it mainly affects the internal jugular vein, isolated cases have been described of involvement of the external jugular vein. The main etiological agent is Fusobacterium necrophorum. CASE REPORT: A 27-year-old male, previously healthy, presented with a 7-day history of sore throat and fever. He was diagnosed with Lemierre's syndrome, coinfection by Bacillus circulans, F. nucleatum and Staphylococcus aureus with an atypical presentation due to the involvement of the external jugular vein and the internal jugular vein. CONCLUSIONS: As far as we are aware, we present the first case of Lemierre's syndrome with these characteristics.

ABSTRACT

BACKGROUND: Invasive pneumococcal disease (IPD) is the leading cause of infectious death worldwide. This study aimed to describe the epidemiology of IPD and the impact of pneumococcal conjugate vaccine-10 (PCV-10) over a 10-year period in Bogotá, Colombia. METHODS: This was a laboratory-based surveillance study of Streptococcus pneumoniae isolated from patients with IPD from 82 hospitals over 10 years in Bogotá, Colombia. Data were compared between two periods: 2007-2011 (before the introduction of PCV-10) and 2012-2017 (after the introduction of PCV-10). RESULTS: In total, 1670 patients with IPD were included in the study between 2007 and 2017. Between 2007 and 2011, the most common serotypes were 14, 1, 6B, 6A and 3. Between 2012 and 2017, the most common serotypes were 19A, 3, 14 and 1. A decrease in the incidence of IPD, particularly in children aged 0-4 years, was noted after the introduction of PCV-10. Importantly, this reduction in incidence was not observed in patients aged ≥50 years. CONCLUSIONS: The IPD burden in Bogotá remained stable between 2007 and 2017. The incidence of IPD decreased in children but not in older adults. The introduction of PCV-10 led to a change in the most prevalent serotypes to serotypes that are not included in PCV-10.

ABSTRACT

Resumen Se presenta el caso de una mujer de 78 años de edad con fibrosis pulmonar idiopàtica, quien consultó por exacerbación de sus síntomas respiratorios, a quien se le realizan estudios radiológicos, donde se evidencia dilatación de la vía aérea, previamente no descrita, y se realiza diagnóstico de síndrome de Mounier Kuhn. Hasta donde el conocimiento alcanza, es el primer caso reportado en Colombia y la tercera persona de mayor edad reportada en el mundo. Este es un hallazgo incidental, dado que desde el punto de vista fisiopatológico no hay ninguna relación causal entre la fibrosis pulmonar idiopática y el síndrome de Mounier Kuhn. Sin embargo, su presencia puedo afectar aún más el compromiso funcional, dado el eventual colapso de la vía aérea, lo cual puede llevar a intervenciones terapéuticas adicionales, como colocación de stent. (Acta Med Colomb 2017: 42-198-201).


Abstract The case of a 78-year-old woman with idiopathic pulmonary fibrosis who consulted for exacerbation of her respiratory symptoms is presented. Radiologic studies showed dilation of the airway that was not previously described, and for this reason the diagnosis of Mounier Kuhn Syndrome was made. To our knowledge, this is the first case reported in Colombia and the third oldest person reported in the world. This is an incidental finding, since from the pathophysiological point of view there is no causal relationship between idiopathic pulmonary fibrosis and Mounier Kuhn's syndrome. However, its presence may further affect the functional compromise, given the eventual collapse of the airway, which may lead to additional therapeutic interventions, such as stent placement.
