The state of health of the Minister of the General Secretariat of the Presidency (Segpres), Ana Lya Uriarte, who presented a medical leave due to Long COVID or Long COVID, has generated alarm around this phenomenon that makes her know little scientifically and which is related to symptoms such as sleep changes, low saturation, tiredness, fatigue, shortness of breath, others
The director of the immunology program at the University of Chile and a doctor in biomedical sciences, Mercedes López Nitsche, says that this long COVID is “a post-infectious syndrome next to infection by COVID-19, or by the sea, by SARS infection. “. -CoV-2”. It is clear that “post-infectious or post-viral syndromes are nothing new, it is not something exclusive to SARS-COV2, not even very rare”. 2 and other viruses. And other viruses are also characterized by variable frequency and diversified syntax. ” In this feeling, there are those who face “Ebola, dengue, polio, chikungunya and other pathogens that are not their virus. ” For H1N1 flu, it also describes post-infectious syndromes. “
“In the case of the SARS-CoV-2 virus, this post-infectious syndrome is characterized through those 3 years of pandemic that we have lived through and now we know a lot about this subject. But it is true that what does occur are at least two basic things: a dysregulation of the immune reaction that produces a tissue disease – on the day of the lesions – and/or autoimmunity and/or a prolonged inflammatory or subinflammatory syndrome related or not to viral persistence. In context, there is an alteration of the immune formula produced through viral infection, which is due to the viral infection or because the virus is well controlled by Americans in space.
La doctora López agrega que “lo segundo es que es efectivamente una condición que es clínicamente muy diversa. Hay algunos síntomas que son más frecuentes entre los pacientes, como -por ejemplo- la fatiga, el cansancio, los dolores musculares, alteraciones en el sueño, y algunos que son menos frecuentes, como alteraciones metabólicas o alteraciones cardiovasculares”, los cuales pueden tener gran impacto en la calidad de vida de las y los pacientes, en sus relaciones personales o familiares y a sus relaciones laborales”.
La doctora López explica que hay cuatro cosas en las que debemos fijarnos. La primera es tener un antecedente previo cercano de una infección por COVID agudo, estando vacunados o no vacunados. Lo segundo es que estos síntomas permanezcan entre dos a tres meses después de terminar el COVID agudo. Lo tercero, que haya una gama de síntomas característicos como fatiga, disnea, tos persistente, dolores musculares, cansancio, alteraciones cognitivas, alteraciones del sueño, pero que también existan muchos otros que tienen que ser buscados en estos pacientes y que ninguno de estos síntomas tenga una razón, que no tengan ninguna otra causa y que no vengan de antes.
Finally, the specialist adds, most importantly, “it is also important what influences, what influences the lives of patients. ” Explains why other people suffer and the quality of life.
What is known to the point of being consistently resistant to COVID is that “the prevalence has been replaced over time. Early studies imply a very high prevalence, probably because they are closely related to the early years. Some studies say that they may have a prevalence of 30 or 40 percent of those infected, but they have been slow over time and today the most conservative studies have said that they will not have a trend towards a more significant prevalence in 2 consistent cent.
Regarding the implications of vaccination, the doctor says that “vaccines can reduce the prevalence of long COVID, or we know that a vaccinated user has a lower chance of contracting long COVID, but not zero. The option exists and we have patients who are vaccinated and who are presenting long COVID today.
La doctora de la Universidad de Chile explica que “el virus produce, además de la infección aguda, alteraciones en el sistema inmune, ya sea porque alteró el sistema inmune o porque, de alguna manera, persiste en el organismo el virus y se traduce en este síndrome o en esta condición”.
It is because of this explanation that “it has cost a lot and it is very complicated today (to diagnose it), because long COVID is a condition with many different symptoms, that is, patients start with many different symptoms and they themselves with different symptoms. “It is very complicated to synthetically outline long COVID and the other thing, which is very vital for you, which are the symptoms that regularly come from you, the sea, the symptoms that the patient may be fine, they spend a while and then it looks like symptoms again. , and so is the vintage of long COVID. “
Regarding the data of the cases that were presented to the press through Minister Uriarte, Dr. Mercedes López indicates that “persistent COVID, in general, lasts a quarter of a length. When one enjoys its symptoms, something like this, like As time goes by, I have learned for a few months, not a day, that patients visit to decrease their symptoms and over the year or two years, there is a small fraction of patients who continue to have symptoms. conscious for several months, so it is not It is rare that the data is similar to the need for extended leaves for these patients, because the symptoms are complex to bring to light a high-level job.
