ABSTRACT
ABSTRACT

Background:

During the first pandemic wave, Covid-19 reached Latin America cities.

Aim:

To report clinical features and outcomes of a group of patients with Covid-19 admitted to a Chilean regional reference Center. Material and

Methods:

Cases were identified by a compatible clinical picture and a positive PCR or serological test. Clinical features of patients were retrieved from medical records.

Results:

Forty-seven adult patients (45 diagnosed by PCR, 2 by serology) were admitted between epidemiological weeks 13 to 33, corresponding to 4.4% of total regional cases. Hospitalization occurred at a median of 10 days after onset of symptoms. Fifty one percent of patients had 60 years or more. Hypertension, obesity and diabetes mellitus were present in 57, 45 and 32 % of cases, respectively. Nineteen percent of patients had no comorbid condition nor were elderly. Two cases were women in their second trimester of pregnancy. Positive IgM or IgM/IgG results obtained by rapid serological testing, had limited sensitivity during the first week (67%). Seventeen patients (36.2%) were transferred to an intensive care unit (ICU) due to respiratory failure. Chest imaging demonstrated a classical COVID-19 pattern in 87%. By univariate analysis, admission to ICU was significantly associated with tachypnea and higher CALL (comorbidity, age, lymphocyte count and lactate dehydrogenase) score. Four patients died (rendering a hospital mortality of 8.5%) and length of stay was ≥ 14 days in 46.8% of patients. By univariate analysis, mortality was associated with immunosuppression and ICU admission.

Conclusions:

In our regional Center, patients admitted with COVID-19 had usual risk factors and had a prolonged stay. Hospital mortality was associated with immunosuppression and ICU admission.
RESUMEN
Antecedentes Durante la primera ola pandémica, COVID-19 llegó a las ciudades de América Latina.

Objetivos:

Informar las características clínicas y los resultados asociados a COVID-19 en un grupo de pacientes ingresados en un Centro de referencia regional en el sur de Chile. Material y

Métodos:

Los casos fueron identificados por un cuadro clínico compatible asociado a RT-PCR positiva o prueba serológica. La información clínica de los pacientes se obtuvo de sus fichas.

Resultados:

Entre las semanas epidemiológicas 13 y 33 ingresaron 47 pacientes adultos (45 diagnosticados por PCR, 2 por serología), lo que representa el 4,4% del total de casos regionales. La hospitalización se produjo con una mediana de 10 días después del inicio de los síntomas. El 51% de los pacientes tenía 60 años o más. La hipertensión arterial (57,4%), la obesidad (44,7%) y la diabetes mellitus 2 (31,9%) fueron prevalentes, pero el 19% no presentaba comorbilidades ni era un adulto mayor. Dos casos ocurrieron en mujeres embarazadas en el segundo trimestre. Los resultados positivos de IgM o IgM / IgG obtenidos mediante pruebas serológicas rápidas tuvieron una sensibilidad limitada durante la primera semana (66,7%). Diecisiete pacientes (36,2%, grupo crítico) fueron trasladados a UCI por insuficiencia respiratoria. Las imágenes de tórax demostraron un patrón COVID-19 clásico en el 87% de los casos. Por análisis univariado, el ingreso en UCI se asoció significativamente con taquipnea y puntuaciones CALL (comorbidity, age, lymphocyte count and lactate dehydrogenase) elevadas. Cuatro pacientes fallecieron (mortalidad hospitalaria 8,5%) y la estadía hospitalaria fue ≥ 14 días en el 47% de los pacientes. Por análisis univariado la mortalidad se asoció a inmunodepresión y al ingreso a UCI.

Conclusiones:

En nuestro Centro regional, COVID-19 se asoció a factores de riesgo conocidos y tuvo una estadía prolongada. La mortalidad hospitalaria se asoció con inmunosupresión o ingreso a UCI.
