Riesgo de COVID largo por síntomas previos a la infección y estado funcional: un estudio de cohorte retrospectivo de
medRxiv : the preprint server for health sciences
|August 20, 2025
Resumen
Los síntomas preexistentes y la peor salud mental antes de la infección aumentaron el riesgo de COVID prolongado. El COVID prolongado es un cambio significativo en la salud, incluso para aquellos con condiciones previas, lo que pone de relieve la necesidad de una evaluación del estado funcional.
Área de la Ciencia:
- Investigaciones médicas
- Salud pública
- Epidemiología
Sus antecedentes:
- Más de siete millones de adultos estadounidenses experimentan COVID prolongado, problemas de salud persistentes después de COVID-19.
- Las pautas sugieren incluir el estado funcional en los diagnósticos de COVID prolongados, pero la evidencia es limitada.
- Este estudio investiga los factores previos a la infección que influyen en el desarrollo de la COVID a largo plazo y la viabilidad de la evaluación del estado funcional.
Objetivo del estudio:
- Explorar las probabilidades ajustadas de desarrollar COVID largo en función de los síntomas previos a la infección y el estado funcional.
- Evaluar la viabilidad de estimar el estado funcional antes de la infección utilizando registros electrónicos de salud.
- Informar los criterios de diagnóstico para el COVID largo mediante la comprensión de los factores de riesgo.
Principales métodos:
- Estudio de cohorte retrospectivo utilizando la base de datos All of Us CDR 7.0.
- Incluyó a adultos estadounidenses con antecedentes de COVID-19, analizando registros de salud y datos de encuestas hasta julio de 2022.
- Síntomas y estado funcional examinados antes de la infección (5 años antes), ajustados por las covariables.
Principales resultados:
- N = 65.464 participantes cumplieron con los criterios de inclusión; 40.655 desarrollaron síntomas de COVID prolongados.
- El aumento de las probabilidades de COVID prolongado se correlacionó con una menor autoevaluación de la salud mental antes de la infección (AOR = 1,14) y una mayor carga de síntomas.
- No se encontró una asociación significativa entre los síntomas previos a la infección, la capacidad física autoevaluada o el deterioro funcional documentado y las probabilidades de COVID prolongado.
Conclusiones:
- Una mayor carga de síntomas previos a la enfermedad y una menor autoevaluación de la salud mental se asocian con mayores probabilidades de COVID prolongado.
- El COVID largo significa una disminución notable en la salud y el funcionamiento desde el punto de partida, incluso con condiciones previas.
- El uso de registros electrónicos de salud armonizados es factible para estimar el estado funcional antes de la infección, ayudando a los diagnósticos de COVID a largo plazo.

Stages of Infection
58.9K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Factors Affecting the Risk of Infection
12.2K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
2.9K
Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

COPD: Pathogenesis and Clinical Features
512
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Classification of Illness
7.9K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
