ABSTRACT
ABSTRACT The precise pathogenesis of COVID-19-related multisystem inflammatory syndrome remains largely elusive, despite its rarity. The syndrome symptoms often overlap with those of other infections, posing challenges for prompt diagnosis. A male patient, 34 years old, was admitted with suspicion of severe dengue, rapidly progressing to multiple organ dysfunction. Dengue tests resulted negative, and he passed away after four days. This case occurred approximately four weeks after the initial onset of COVID-19 and met all diagnostic criteria as defined by the Centers for Disease Control and Prevention. This report presents the first documented case of fatal multisystem inflammatory syndrome in adult (MIS-A) in Brazil. Recognizing the significance of suspecting this syndrome and promptly initiating treatment at an early stage are essential for minimizing damage and mortality.
ABSTRACT
ABSTRACT This study aimed to evaluate the COVID-19 hospitalizations in a tertiary hospital by age group and month, considering the introduction and the advance of the vaccination against the disease. The laboratory-confirmed COVID-19-associated hospitalizations among people aged 20 years or older, that occurred between March 2020 and June 2021, were distributed by month of symptom onset and age group. The proportion of hospitalizations by age group was calculated for the year 2021. The proportions were compared using the chi-square test for trends. The marks of vaccination advances among different age groups were taken from the official website LocalizaSUS. In 2020, hospitalizations among people aged 60-80 years old were the most frequent (39.1%). From January-June 2021, when the vaccination commenced, while hospitalizations of patients aged 20 to < 40 and 40 to 60 years old showed an increasing trend, the older age groups and those with vaccination recommendations (from 60 to < 80 and from 80 or over) showed a downward trend. As of June 2021, with widespread vaccination, a drop in hospitalizations was observed in > 60 years old. At 20 to <40 and 40 to < 60, an increase in hospitalizations was observed. It demonstrates the important role of vaccination in combating the COVID-19 pandemic.
