The study has not yet been peer reviewed and published as a preprint, one has already attracted the attention of the medical community. Scientists conducted a survey of the parents of 518 children under 18 years of age (average age 10 years), who were hospitalized at the D.G. Bashlyaeva from April to August last year.
The results showed that in a quarter of patients (24.3%) COVID-19 symptoms persisted for seven to nine months after discharge. Most often, parents reported constant fatigue (10%), sleep disturbances (7%), loss of smell and taste (6%). Complex symptoms were found in 8.4% of children in this cohort. It is noteworthy that children 12-18 years old, as well as those with a history of allergies, are at the greatest risk of postcoid manifestations.
“The most common problem is fatigue. You have to understand that we are not talking about fatigue for one or two days, we are talking about a persistent symptom, the cause of which must be determined, “The Guardian quotes one of the authors of the study, a pediatrician at Sechenov University, Daniel Moonblit.
According to the study, 16% of young patients began to experience chronic fatigue shortly after discharge, and within a few months this figure dropped to 12%. However, later the dynamics of the decline slowed down significantly and after seven months, 11% of children still suffered from a loss of strength and energy. In more than 8% of children, the sense of smell did not return after discharge and at the time of the survey did not recover in 6%.
Earlier, Italian and Russian scientists conducted a similar survey among educators and educators of 129 children, most of whom suffered the infection easily or asymptomatically. The total follow-up period from the moment of diagnosis was 163 days. Only 42% of patients recovered completely, more than half of the children had at least one symptom 120 days after COVID-19 was detected. 36% of them had one or two signs of postcoid syndrome, 23% – three or more.
Most often, children complained of insomnia (18.6%), chest tightness and pain (14.7%), nasal congestion (12.4%), muscle pain 10.1%). Also, teachers noted rapid fatigability (10%) and problems with concentration (10%). Some children reported persistent joint aches, headaches, and heart palpitations. In 43% of cases, the symptoms of PTS were so severe that they made it difficult to lead a fulfilling life.
It is noteworthy that the symptoms of the long covid syndrome were detected even in those young patients who were asymptomatic carriers of the infection.
