[Clinical features, risk factors and susceptibility profile of mycobacterial infections documented by culture in a university hospital of high complexity in Medellin (Colombia)]. / Características clínicas, factores de riesgo y perfil de susceptibilidad de las infecciones por micobacterias documentadas por cultivo, en un hospital universitario de alta complejidad en Medellín (Colombia).

INTRODUCTION: Tuberculosis (TB) remains an entity of high prevalence and mortality worldwide. The rising drug resistance is a public health problem. Besides, non-tuberculosis mycobacterial (NTM) infections are described with increasing frequency in areas of high prevalence of TB. OBJECTIVES: To determine epidemiological, clinical and microbiological characteristics of mycobacterial infections documented by culture. MATERIALS AND METHODS: An observational, descriptive study in hospitalized patients. RESULTS: M. tuberculosis complex was identified in 90,9% of 187 patients; 9,1% had NTM, 64% were male and the mean age was 40 years (range 1-88 years). The main co-morbidities were HIV / AIDS (23.5%), use of corticosteroids (13.3%) and chronic kidney disease (9.6%). Clinical forms were pulmonary (56.6%), extra-pulmonary (23.9%) and disseminated (19.2 The most common extra-pulmonary compromise was nodal (7.4%) and gastrointestinal (7%). 10.6% of M. tuberculosis were multi-drug resistant (MDR) and 2.12% had extended drug resistance (XDR). Mycobacterium avium andM. abscessus were the most frequent NTM. Overall mortality was 10%. CONCLUSIONS: In our study immune suppression is the main risk factor for extrapulmonary and disseminated disease. Resistance, MDR and XDR is higher in inpatients with TB. MNT infections are not uncommon in our country.

Effectiveness and safety of once-weekly semaglutide: findings from the SEMACOL-REAL retrospective multicentric observational study in Colombia.

Introduction: Diabetes stands as one of the leading causes of death worldwide. Glucagon-like peptide-1 receptor agonists rank among the most effective medications for lowering blood glucose and body weight, as well as reducing cardiovascular risk in individuals with diabetes. Observational studies complement experimental evidence in new settings, different populations, and real-world healthcare practices. Methods: A multicentric observational study of adults with type 2 diabetes treated with once-weekly subcutaneous semaglutide in four health centers in Colombia was conducted. The protocol for the present study was not pre-registered. Results: Data from 186 patients were included. Most patients were women (57%) with a mean age of 62.8 ± 12.1 years. One year of once-weekly semaglutide usage was associated with a mean reduction in HbA1C of -1.47% (95% CI -1.76, -1.17), weight loss of -4.23 kg (95% CI -5.34, -3.12), and albumin/creatinine ratio of -18.6 mg/g (95% CI -60.2, -5.9). Approximately half the treated patients achieved a level of HbA1c ≤7% by the end of follow-up. Adverse events were rare and consistent with clinical trial safety profiles. Conclusion: In Colombia, administering semaglutide subcutaneously once a week over a 1-year period led to an average weight loss of 4.2 kg and a decrease of 1.4% in HbA1c.

Posterior Reversible Encephalopathy Syndrome as an Adverse Effect of Lenvatinib in a Patient with Papillary Thyroid Carcinoma: A Case Report.

Posterior reversible encephalopathy syndrome (PRES) is an uncommon transient neuroradiological phenomenon that develops vasogenic cerebral edema and could be caused by some pharmacological agents, such as molecular-specific target agents. Lenvatinib belongs to the tyrosine kinase inhibitors and was approved in 2015 for progressive locally advanced or metastatic thyroid cancer refractory to radioactive iodine (I-131) treatment. Herein, we present the case of a 65-year-old woman who, while receiving treatment with lenvatinib for radioiodine-refractory metastatic papillary thyroid carcinoma, developed PRES without hypertension at the initial evaluation. Her clinical and radiological findings improved after withdrawing from the mentioned therapy, and later it was possible to re-incorporate lower doses of the medication, as described in the other three case reports found in the worldwide medical literature. The recognition of this entity is essential to timely suspend the drug and avoid greater comorbidity. This is the first paper reporting this kind of adverse event using lenvatinib in a Hispanic population.

COVID-19 y tiroides. Revisión de la literatura y recomendaciones para pacientes con enfermedad tiroidea / Thyroid and COVID-19. Review and recommendations for patients with thyroid disease

Resumen Las enfermedades de la tiroides, tanto benignas como malignas, son altamente prevalentes a nivel mundial, por lo que es muy probable que durante la pandemia por SARS-CoV-2 veamos pacientes con ambas enfermedades. Esto exige el conocimiento de las implicaciones potenciales de este nuevo virus en el funcionamiento de la glándula, en los tratamientos usuales para estas enfermedades y en consideraciones especiales para este grupo poblacional. A la fecha no hay evidencia que soporte que las enfermedades tiroideas aumenten el riesgo de infección o severidad de la enfermedad; sin embargo, es posible que durante infecciones severas por SARS-CoV-2 en personas con o sin antecedente de enfermedad tiroidea puedan presentar alteración de las pruebas tiroideas, aunque transitoriamente y sin requerimiento de tratamiento específico. Es fundamental que los pacientes continúen con sus tratamientos ambulatorios y se difiera, en la medida de lo posible, los procedimientos quirúrgicos o la administración de yodo radioactivo hasta que se considere seguro realizarlos.

Abstract Both benign and malignant thyroid diseases are highly prevalent worldwide, so it is highly likely that during the COVID-19 pandemic we will see patients with this comorbidity. This requires knowledge of the potential implications of this new virus in the functioning of the gland, the usual treatments for these diseases and special recommendations in this population. To date, there is no evidence to support that thyroid diseases increase the risk of infection or the disease severity. However, it is possible that during severe SARS-CoV-2 infections in people with or without history of thyroid disease, the thyroid tests may be altered, although transitory and does not require specific treatment. It is essential for patients to continue with their outpatient treatments and defer as far as possible surgical procedures or administration of radioactive iodine until it is considered safe to perform.

Experiencia clínica con infecciones causadas por Klebsiella pneumoniae productora de carbapenemasa, en una institución de enseñanza universitaria en Medellín, Colombia / Clinical experience with infections caused by carbapenemase-producing Klebsiella pneumoniae in a tertiary care teaching institution in Medellin, Colombia

Antecedentes: Las infecciones por Klebsiella pneumoniae productora de carbapenemasa (KPC) son un problema de salud pública mundial. Desde 2008 nuestra institución experimenta casos endémicos de infecciones por KPC posteriores a un brote cuyo caso índice fue un paciente de Israel admitido para trasplante hepático. Objetivo: Describir características clínicas y mortalidad en pacientes hospitalizados con infecciones nosocomiales por KPC. Métodos: Estudio observacional retrospectivo, descriptivo. Resultados: Un total de 52 pacientes fueron incluidos, la edad media fue 45,7 ± 27 años, 65,4% fueron hombres. Uso de inmunosupresores, cirugía gastrointestinal, hepatopatía crónica y trasplante de órgano sólido fueron las comorbilidades importantes. El 100% recibió antibióticos antes de la infección por KPC. Las principales infecciones fueron bacteriemia (30,7%), infección intraabdominal (23,1%) y neumonía (17,3%). El tratamiento fue dirigido por antibiograma en 50,7%. Tigeciclina fue administrada en el 51,9% y colistina en el 32,7%, ambas en terapia combinada con otros antibióticos. En el 15,4% se utilizó tigeciclina más colistina. La duración del tratamiento fue 15,7 ± 7,5 días. El 51,9% desarrolló bacteriemia y falla renal aguda y el 76,9% requirió atención en UCI. La mortalidad fue 48,1% y fue significativamente mayor en pacientes con bacteriemia vs. sin bacteriemia (74,1 vs. 20%; p = 0,01). No hubo diferencias significativas en mortalidad cuando se comparó uso de tigeciclina vs. colistina (45 vs. 52%; p = 0,609). Conclusión: La inmunosupresión, cirugía gastrointestinal, tratamiento previo con antibióticos y estancia en UCI son factores importantes para la infección por KPC. La mortalidad es alta a pesar de la terapia dirigida, especialmente en pacientes con bacteriemia.

Background: Carbapenemase-producing Klebsiella pneumoniae (KPC) infections are a worldwide public health problem. Since 2008, our institution has experienced endemic cases of KPC infection after an outbreak whose index case was a patient from Israel admitted for liver transplantation. Objective: To describe the clinical characteristics and mortality of inpatients with nosocomial KPC infections. Methods: Retrospective, descriptive observational study. Results: A total of 52 patients were included, with an average age of 45.7 ± 27 years; 65.4% were men. Use of immunosuppressants, gastrointestinal surgery, chronic liver disease and solid organ transplantation were significant comorbidities. All the patients had received antibiotics before the KPC infection. The primary infections were bacteraemia (30.7%), intra-abdominal infections (23.1%) and pneumonia (17.3%). Treatment was directed by antibiogram in 50.7% of cases. Tigecycline was administered in 51.9% of cases and colistin in 32.7%, both in combination therapy with other antibiotics. Colistin plus tigecycline was used in 15.4% of cases. The treatment duration was 15.7 ± 7.5 days, with 51.9% of patients developing bacteraemia and acute renal failure and 76.9% requiring ICU care. Mortality was 48.1% and was significantly higher in the patients with bacteraemia compared with those without (74.1 vs. 20%, respectively, p = 0.01). There were no significant differences in mortality between tigecycline and colistin use (45 vs. 52%, respectively, p = 0.609). Conclusion: Immunosuppression, gastrointestinal surgery, previous treatment with antibiotics and ICU stay are important factors for infection with KPC. Mortality is high despite targeted therapy, particularly in patients with bacteraemia.

Introducción: Tuberculosis (TBC) es aún una entidad de alta prevalencia y mortalidad en el mundo. La resistencia ascendente a fármacos es un problema de salud pública. Además se describen con mayor frecuencia infecciones por micobacterias no tuberculosas (MNT) en áreas de alta prevalencia de TBC. Objetivos: Determinar características epidemiológicas, clínicas y microbiológicas de las infecciones por micobacterias documentadas por cultivo. Materiales y Métodos: Estudio observacional, descriptivo, en pacientes hospitalizados. Resultados: De 187 pacientes, en 90,9% se identificó complejo M. tuberculosis y en 9,1% MNT; 64% fueron hombres. Edad promedio 40 años (rango 1-88 años). Las principales co-morbilidades fueron infección por VIH/SIDA (23,5%), uso de corticoesteroides (13,3%) y enfermedad renal crónica (9,6%). Las formas clínicas fueron pulmonares (56,6%), extra-pulmonares (23,9%) y diseminadas (19,2%). El compromiso extra-pulmonar más frecuente fue ganglionar (7,4%) y gastrointestinal (7%). En M. tuberculosis 10,6% fueron multidrogoresistentes (MDR) y 2,12% con resistencia extendida (XDR). Mycobacterium avium y M. abscessus fueron las MNT más frecuentes. La mortalidad general fue 10%. Conclusiones: Inmuno-supresión es el principal factor de riesgo para enfermedad extrapulmonar y/o diseminada y la resistencia a fármacos en pacientes hospitalizados con TBC es llamativa, con mayor incidencia de MDR y XDR. Las infecciones por MNT no son infrecuentes en nuestro medio.
