RESUMO

Resumen: Los pacientes con infección por VIH tienen una mayor incidencia de eventos cardiovasculares en comparación con la población general; los factores que contribuyen al incremento del riesgo de eventos cardiovasculares son la prevalencia de factores de riesgo cardiovascular tradicionales (FRCV), la infección por VIH que condiciona tanto un proceso de inflamación crónica como alteración de la función endotelial y la exposición a los antirretrovirales. Los factores que deben ser objeto de intervención son los FRCV tradicionales, en especial la alta tasa de fumadores entre este grupo de pacientes, la tamización y tratamiento de HTA, el síndrome metabólico y el acceso temprano a la terapia antirretroviral con medicamentos con mayor perfil de seguridad . Esta guía pretende proveer información y recomendaciones en el ámbito nacional acerca de la relación entre la infección por VIH/SIDA (Síndrome de Inmunodeficiencia Adquirida), uso de antirretrovirales y riesgo cardiovascular.


Abstract: Patients with VIH infection have greater risk for cardiovascular diseases compared to general population. Risk factors that increase the frequency of cardiovascular events are: presence of cardiovascular traditional risk factors, chronic inflammation by HIV that impairs endothelial function and the exposure to antiretrovirals. The factors that should be the target for intervention are the traditional know cardiovascular factors such, especially high rate of smokers, screening and treatment for hypertension, metabolic syndrome and early access to HAART. The present guidelines provides information about the use of antiretrovirals in patients with HIV and its relation with cardiovascular risk.

RESUMO

PURPOSE: To analyze the prognostic role of positive cultures in patients with sepsis. METHODS: A prospective cohort study in a tertiary referral hospital in Medellín, Colombia. Adults older than 18 years of age with a bacterial infection diagnosis according to Centers for Disease Control criteria and sepsis (evidence of organ dysfunction) were included. A logistic regression model was used to determine the association between positive cultures and hospital mortality, and a Cox regression with a competing risk modeling approach was used to determine the association between positive cultures and hospital stay as well as secondary infections. RESULTS: Overall, 408 patients had positive cultures, of which 257 were blood culture, and 153 had negative cultures. Patients with positive cultures had a lower risk of mortality (odds ratio [OR], 0.43; 95% confidence interval [CI], 0.27-0.68), but this association was not maintained after adjusting for confounding factors (OR, 0.56; 95% CI, 0.31-1.01). No association was found with the hospital stay (adjusted subhazard ratio [SHR], 1.06; 95% CI, 0.83-1.35). There was no association between positive cultures and the presence of secondary infections (adjusted SHR, 0.99; 95% CI, 0.58-1.71). CONCLUSION: Positive cultures are not associated with prognosis in patients with sepsis.

RESUMO

Resumen Objetivo: evaluar la mejor evidencia actual disponible para generar recomendaciones con respecto a la efectividad y seguridad del uso de tigeciclina en adultos con infección de piel y tejidos blandos (IPTB). Materiales y métodos: se realizó una revisión sistemática de la literatura, seleccionando los metaanálisis y experimentos clínicos controlados (ECCs), los cuales se valoraron utilizando la herramienta SIGN (Scottish Intercollegiate Guidelines Network.), con el fin de generar tablas de evidencia según GRADE de los estudios de tigeciclina en la indicación de IPTB, para posteriormente utilizar un proceso Delphi modificado para calificar las diferentes recomendaciones. Resultados: la revisión sistemática se incluyeron 9 metaanálisis que incluyeron 5 estudios clínicos aleatorizados con 1873 pacientes, y de ellos 952 asignados al brazo de tigeciclina, no mostró inferioridad frente a los comparadores en curación clínica (RR= 0.76 IC95% 0,57 - 1.03), curación microbiológica (RR= 0.92 IC95% 0,61 - 1.38), eventos adversos serios RR 1,41 (IC95%0,97 a 2,35), ni mortalidad RR 1,9 (IC95%0,84 a 4,3). La tigeciclina puede relacionarse con mayor frecuencia de eventos adversos leves de origen gastrointestinal. Conclusión: en pacientes adultos con IPTB, se considera que el uso de tigeciclina en monoterapia en pacientes no críticamente enfermos es equivalente en eficacia a otras opciones terapéuticas antimicrobianas. Se debe considerar especialmente como terapia de ajuste en pacientes con infecciones polimicrobianas.


Abstract Objective: To assess current best evidence available to generate recommendations regarding the effectiveness and safety of tigecycline use in adults with skin and soft-tissue infections (SSTIs). Materials and methods: A systematic review of the literature was conducted by selecting meta-analyzes and controlled clinical trials (CCTs), which were assessed using the SIGN tool (Scottish Intercollegiate Guidelines Network) in order to generate evidence tables according to GRADE of studies of tigecycline in the SSTIs indication, and then using a modified Delphi Method to score the different recommendations. Results: Nine meta-analyzes were included compounded by five randomized clinical trials with a sample size of 1873 patients, where 952 patients were assigned to tigecycline. The group of patients with tigecycline showed no inferiority to the comparator in clinical cure (RR = 0.76 95% CI 0.57 - 1.03), microbiologic cure (RR = 0.92 95% CI 0.61 - 1.38), serious adverse events RR 1, 41 (95% CI 0.97 to 2.35) or mortality RR 1.9 (95% CI 0.84 to 4.3). Tigecycline may be related to increased frequency of minor adverse events of gastrointestinal origin. Conclusion: In adult patients with SSTIs, it is considered that the use of tigecycline in monotherapy in non-critically ill patients is equivalent in effectiveness to other antimicrobial treatment options. It should be especially considered as an adjustment therapy in patients with polymicrobial infections.

Abstract Objective: To assess current best evidence available to generate recommendations regarding the effectiveness and safety of tigecycline use in adults with complicated intra-abdominal infection (cIAIs). Materials and methods: We conducted a systematic review of published meta-analysis that evaluated tigecycline compared to other antimicrobials and included the indication of cIAI. Quality of the evidence was evaluated by using the SIGN tool (Scottish Intercollegiate Guidelines Network) according to GRADE, and final recommendations were assessed by a modified Delphi Method in order to develop a consensus. Results: Five meta-analyzes met the selection criteria comparing tigecycline with other antibiotic treatments in complicated intra-abdominal infection. Five randomized clinical trials comprised in these meta-analysis included 2711 patients that received at least one dose of antibiotic (1382 tigecycline and 1389 the comparator regimen), We found no statistically significant differences in the evaluated outcomes by comparing tigecycline with other antibiotics, including clinical and microbiologic efficacy, safety and drug related mortality Conclusion: In adult patients with cIAIs, the use of tigecycline as monotherapy is equivalent in effectiveness to other antimicrobial therapeutic options and does not represent an increase in mortality compared to other antibiotics.

RESUMO

Resumen: El citomegalovirus es una de las principales causas de infección y enfermedad en receptores de trasplante renal, con un notorio impacto en términos de morbilidad, mortalidad y costos. Sin embargo, no existe en Colombia una práctica clínica estandarizada entre los centros de trasplante, por lo cual, es de suma importancia disponer de guías con el fin de orientar la estratificación, el diagnóstico de laboratorio, el tratamiento y la prevención de la infección y enfermedad por citomegalovirus en pacientes adultos con trasplante renal. A través de la metodología ADAPTE para la evaluación de calidad y transculturización de guías de práctica clínica a nuestro medio, un grupo multidisciplinario realizó una revisión sistemática de la literatura: se seleccionaron las guías internacionales, las cuales fueron evaluadas con el instrumento AGREE II en términos de calidad. Con la guía base seleccionada se buscó la evidencia existente para contestar a las preguntas, de acuerdo con el método de desarrollo de recomendaciones GRADE. Se realizaron recomendaciones para la estratificación, el diagnóstico, el tratamiento y la prevención de la infección y enfermedad por citomegalovirus en pacientes adultos con trasplante renal en Colombia.


Abstract: Cytomegalovirus is a primary cause of infection and illness in patients who have had renal transplantation, with a significant impact on morbidity, mortality and economic costs. However, there is no standardized clinical practice in transplant centers in Colombia, and it is important to have guidelines to stratify, diagnose, treat and prevent cytomegalovirus infection and disease. Through ADAPTE's methodology for the quality evaluation and adaptation of clinical practice guidelines in our setting, a multidisciplinary group carried out a systematic review of the medical literature, selecting international guidelines that were evaluated with the AGREE-II instrument in terms of quality. With each selected guideline, an evidence table was constructed and the GRADE strategy was performed to develop recommendations. Recommendations related to stratification, laboratory diagnosis, treatment and prevention of infections and disease caused by cytomegalovirus in adult transplant patients were developed.

RESUMO

Tuberculous lymphadenitis is the most common extrapulmonary manifestation of disseminated tuberculosis (TB). It is considered to be the local manifestation of the systemic disease that has disseminated to local lymph nodes, but a high index of suspicion is needed for the diagnosis, because there are several infectious and noninfectious diseases that can mimic the same clinical picture. In recent years, different diagnostic methods have been introduced, including fine-needle aspiration cytology, which has emerged as a simple outpatient diagnostic procedure that replaced the complete excisional node biopsy, and a number of molecular methods which have greatly improved diagnostic accuracy. This chapter covers the most actual knowledge in terms of epidemiology, clinical manifestations, pathogenesis, and treatment and emphasizes current trends in diagnosis of tuberculous lymphadenitis. TB parotid gland involvement is extremely rare, even in countries in which TB is endemic. Because of the clinical similarity, parotid malignancy and other forms of parotid inflammatory disease always take priority over the rarely encountered TB parotitis when it comes to differential diagnosis. As a result, clinicians often fail to make a timely diagnosis of TB parotitis when facing a patient with a slowly growing parotid lump. This chapter highlights the most important features of this uncommon disease.

RESUMO

The use of biological therapy has been linked with an increased risk of tuberculosis (TB) reactivation. The aim of this study was to present the follow-up results for isoniazid (INH) chemoprophylaxis in patients receiving different biological therapies. In this prospective observational study, patients with latent tuberculosis infection (LTBI) were given INH chemoprophylaxis between 2 and 9 months prior to the beginning of biological therapy. All patients were followed up monthly for any signs or symptoms of active TB or INH toxicity. A total of 221 patients, 122 females (55.2 %), with a mean age of 46.8 ± 11.3 years (16-74) were enrolled. LTBI was identified in 218 patients (98.7 %), all of whom received INH chemoprophylaxis. Seven patients (3.2 %) developed active tuberculosis, and 32 (17.2 %) patients developed intolerance or toxicity related to INH. Chemoprophylaxis with INH seems to be effective and safe for the prevention of most TB reactivation in individuals with LTBI, but toxicity must be monitored during follow-up.

RESUMO

A 39 year-old man came to our institution because of a five-year history of a progressive painful growing mass on his left nostril, which cause airway obstruction with ulceration. Because of a suspicion of malignancy, surgery (mass resection and subtotal nasal reconstruction) was performed. Histologic samples ruled out malignancy, and tissue cultures for fungus and mycobacteria were negative, but regular aerobic cultures were positive for Klebsiella rhinoscleromatis. The patient was given a six-month regimen of ciprofloxacin, and a dramatic improvement was observed.
