A Tale of Two Hospitals: Comparing CAPA Infections in Two ICUs During the Spanish Fourth Pandemic Wave.

PURPOSE: COVID-19 associated pulmonary aspergillosis (CAPA) is a new clinical entity linked to SARS-CoV-2 infection that is causing a rise on the risk of complications and mortality, particularly in critical patients. METHODS: We compared diagnostic and clinical features in two cohorts of patients with severe COVID-19 admitted in the intensive care units (ICU) of two different hospitals in Madrid, Spain, between February and June 2021. Clinical and microbiological relevant aspects for CAPA diagnosis were collected for further classification. CAPA was classified as colonization, possible, probable, proven, and tracheobronchial aspergillosis according to the ECMM/ISHAM consensus, with some modifications to consider tracheobronchial aspirate as sample comparable to non-bronchoscopic lavages (NBL). RESULTS: 56 patients admitted in HULP (Hospital Universitario La Paz) ICU and 61 patients admitted in HEEIZ (Hospital de Emergencias Isabel Zendal) ICU had clinical suspicion of invasive fungal disease in the context of COVID-19 infection. Cultures were positive for Aspergillus spp. in 32 patients. According to 2020 European Confederation of Medical Mycology and the International Society for Human and Animal Mycology (ECMM/ISHAM) consensus, 11 patients were diagnosed with possible CAPA and 10 patients with probable CAPA. Global incidence for CAPA was 6.3%. Global median days between ICU admission and diagnosis was 14 day. Aspergillus fumigatus complex was the main isolated species. Antifungal therapy was used in 75% of patients with CAPA suspicion, with inter-hospital differences in the administered antifungals. Global overall mortality rate for CAPA patients was 66.6% (14/21). All-cause mortality in non-CAPA cohorts were of 26.3% in HULP group (34/129) and 56.8% (104/183) in HEEIZ group. CONCLUSIONS: There were no significant differences in incidence between the two hospitals, and differences in antifungal therapy did not correlate with differences in mortality, reflecting that both first-line azoles and Amphotericin B could be effective in treating CAPA infections, according to the current guideline indications.

Traqueotomías en pacientes críticos durante la pandemia por COVID-19. Estudio preliminar de nuestra experiencia en el Hospital Universitario La Paz de Madrid / Tracheotomies in critical patients during the COVID-19 pandemia. Preliminary study of our experiences at La Paz University Hospital of Madrid

El brote epidémico causado por el virus SARS-CoV-2 se encuentra plenamente activo en España. Alrededor del 10-15 % de los pacientes ingresados precisan cuidados en unidades de críticos, siendo intubados de forma prolongada y precisando la realización de traqueotomías. Se realiza un estudio observacional de las traqueotomías realizadas por nuestro Servicio de Cirugía Oral y Maxilofacial a pacientes COVID-19 de unidades de cuidados intensivos realizadas entre el 17 de marzo y el 17 de abril de 2020. El estudio analiza aspectos epidemiológicos y clínicos de los pacientes, el tipo de técnica quirúrgica empleada, el tiempo quirúrgico, el tipo de cánula empleada, las complicaciones postquirúrgicas y el seguimiento clínico de los pacientes. Un total de 22 pacientes fueron sometidos a traquetomía reglada abierta. Fueron dieciocho hombres y cuatro mujeres de edades entre 40 y 77 años (64,9 años de media). En todos los casos la realización de traqueotomía fue como consecuencia del proceso pulmonar por la neumonia bilateral COVID-19. Dos pacientes presentaron un neumotórax en el postoperatorio inmediato como complicación, un paciente falleció durante la realización del procedimiento y otro tras su llegada a la Unidad de Cuidados Intensivos tras la realización de la traqueotomía. A pesar de que la traqueotomía es una técnica quirúrgica reglada, las características especiales de los pacientes COVID-19 hacen de este procedimiento una situación crítica por la inestabilidad pulmonar y la rápida desaturación del paciente. Todo ello obliga a la realización del procedimiento por facultativos con experiencia para disminuir el tiempo quirúrgico y poder enfrentarse a cualquier eventualidad

The outbreak caused by the SARS-CoV-2 virus is currently very active in Spain. Many infected people still require to be hospitalized. Around 10-15 % of hospitalized patients require intensive care, where they are intubated for a prolonged period, needing tracheotomies some weeks after the intubation. We will be conducting an observational study of the tracheotomies performed by our oral and maxillofacial Department to COVID-19 patients on intensive care units between March 17th and April 17th, 2020. This study will be analyzing the patients' epidemiological and clinical aspects, surgical technique employed, surgical time, type of cannula used, postoperative complications and the patients' clinical monitoring. A total of 22 patients underwent open elective tracheotomy. There were twenty-two males and three females aged between 40 and 77 (mean: 64,9 years-old). In all cases tracheotomy was carried out due to pulmonary process caused by COVID-19 bilateral pneumonia. Two patients presented pneumothorax in the immediate postoperatory care as a complication, one perished during the procedure and another did so after arriving to the Intensive Care Unit after the tracheotomy surgery. Even though tracheotomy is a ruled surgical technique, the special characteristics of COVID-19 patients make of this procedure a critical situation, mainly due to lung instability and quick desaturation of the patients. This requires the surgery to be carried out by experienced physicians in order to reduce operative time and to be able to react to any eventualities that may arise
