Short- and mid-term outcomes of multisystem inflammatory syndrome in children: a longitudinal prospective single-center cohort study.

Background: Multisystem inflammatory syndrome in children (MIS-c) emerged during the coronavirus disease 2019 pandemic and is associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Despite the extensively studied clinical manifestation of acute condition, the short- and long-term effects of MIS-c on children's health are unknown.

Methods: This was a prospective longitudinal cohort study.

Comparison of Characteristics and Outcomes of Multisystem Inflammatory Syndrome, Kawasaki Disease and Toxic Shock Syndrome in Children.

Since the first cases of multisystem inflammatory syndrome in children (MIS-C) in April 2020, the diagnostic challenge has been to recognize this syndrome and to differentiate it from other clinically similar pathologies such as Kawasaki disease (KD) and toxic shock syndrome (TSS). Our objective is to compare clinical signs, laboratory data and instrumental investigations between patients with MIS-C, KD and TSS. This retrospective observational study was conducted at the Children's Clinical University Hospital, Latvia (CCUH).

Comparison of Persistent Symptoms After COVID-19 and Other Non-SARS-CoV-2 Infections in Children.

The data on long COVID in children is scarce since children and adolescents are typically less severely affected by acute COVID-19. This study aimed to identify the long-term consequences of SARS-CoV-2 infection in children, and to compare the persistent symptom spectrum between COVID-19 and community-acquired infections of other etiologies. This was an ambidirectional cohort study conducted at the Children's Clinical University Hospital in Latvia.

Clinical features of pediatric post-acute COVID-19: a descriptive retrospective follow-up study.

To date, information on COVID-19 long-term post-recovery sequelae in children and adolescents remains scarce. A retrospective descriptive cohort study was performed by collecting data on 92 patients (age ≤ 18 years). All were evaluated during a face-to-face visit following a specially designed post-COVID-19 symptom assessment protocol at the following stage: 1-3 months after COVID-19 onset.

Case Series of Multisystem Inflammatory Syndrome (MIS-C) in Children during the SARS-CoV-2 Pandemic in Latvia.

The total number of COVID-19 positive cases in Latvia has escalated rapidly since October 2020, peaking in late December 2020 and early January 2021. Children generally develop COVID-19 more mildly than adults; however, it can be complicated by multisystem inflammatory syndrome in children (MIS-C). This case study aims were to assess demographic characteristics and the underlying medical conditions, and clinical, investigative and treatment data among 13 MIS-C patients using electronic medical records.

Persistent clinical features in paediatric patients after SARS-CoV-2 virological recovery: a retrospective population-based cohort study from a single centre in Latvia.

The COVID-19 related state of emergency in Latvia was declared on 12 March 2020. Consequently, Children's Clinical University Hospital in Riga, Latvia, established a postacute outpatient service for individuals after recovery from COVID-19. Although information regarding the epidemiology and clinical features of COVID-19 in children has accumulated, relevant reports about persistent symptoms after recovery are lacking.

Impact of Pediatric COVID-19 on Family Health-Related Quality of Life: A Qualitative Study from Latvia.

Information on family health-related quality of life (FHRQoL) among families of children with the coronavirus disease 2019 (COVID-19) is limited. This qualitative study explores the impact of pediatric COVID-19 on FHRQoL from the parents' perspective. Semi-structured interviews were conducted with parents (n = 20) whose children had tested positive for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
