Evaluation of post-COVID symptoms of the SARS-CoV-2 Delta and Omicron variants in children: a prospective study

The post-COVID-19 syndrome is a new syndrome defined in patients with a history of probable or confirmed SARS-CoV-2 infection, usually within three months of the onset of COVID-19, with symptoms and effects lasting at least 2 months. This study is aimed at comprehensively comparing symptoms of the post-COVID-19 syndrome in children with Delta and Omicron variants. This prospective study included children with COVID-19 followed in hospitalized or outpatient clinics in a tertiary hospital. We used a special questionnaire to ask about the presence of persistent symptoms more than 12 weeks after the initial diagnosis. Patients with positive SARS-CoV-2 PCR were selected randomly and grouped according to the dominant variants in our country at that time as follows: Omicron group (after December 16, 2021); Delta (B.1.617.2) group (August 15, 2021, and December 15, 2021). This study included 200 children, 71 of whom were in the Delta group and 129 of whom were in the Omicron group. Weakness (8.5% vs. 1.6%; p = 0.017), the impact of physical efforts (5.6% vs. 3.9%; p = 0.020), fatigue (22.5% vs. 8.5%; p = 0.009), anxiety disorder (12.7% vs. 0.8%; p = 0.001), and gastrointestinal changes (12.7% vs. 4.7%, p = 0.050) were statistically significantly higher in patients with the Delta variant compared to patients with the Omicron variant. There were no differences between the groups regarding anorexia, anosmia/ageusia, arthralgia, influenza-like symptoms, sleeping disorders, decreased physical activity daily, headache, need for analgesia, concentration and memory disorder, and weight loss (p > 0.05).Conclusion: This study showed that weakness, the impact of physical efforts, fatigue, anxiety disorder, and gastrointestinal changes were more frequent in the Delta group compared to the Omicron group. The incidence of post-COVID-19 syndrome is high in children as well as adults and affects several systems; therefore, it should be kept in mind that children should be followed for post-COVID-19 syndrome

Hemolytic Uremic Syndrome Following Influenza A (H1N1) pdm09 Virus in a 14-Month-Old Girl: Hemolytic Uremic Syndrome Following Influenza

Hemolytic Uremic Syndrome (HUS) is characterized by the clinical triad of microangiopathic non-immune hemolytic anemia, thrombocytopenia, and acute renal failure. There are infections, genetic causes, malignancies, autoimmune diseases, drugs, and many unexplained causes in the etiology of HUS. The most common cause of HUS in children is Shiga toxin-producing Escherichia coli (STEC). In the literature, few influenza A (H1N1) pdm09 virus-related HUS cases are reported. In this case report, a case with hemolytic uremic syndrome associated with influenza A (H1N1) pdm09 virus infection is presented

Pediatric-Onset Chronic Inflammatory Demyelinating Polyneuropathy: A Multicenter Study

Background: To evaluate the clinical features, demographic features, and treatment modalities of pediatric-onset chronic inflammatory demyelinating polyneuropathy (CIDP) in Turkey. Methods: The clinical data of patients between January 2010 and December 2021 were reviewed retrospectively. The patients were evaluated according to the Joint Task Force of the European Federation of Neurological Societies and the Peripheral Nerve Society Guideline on the management of CIDP (2021). In addition, patients with typical CIDP were divided into two groups according to the first-line treatment modalities (group 1: IVIg only, group 2: IVIg + steroid). The patients were further divided into two separate groups based on their magnetic resonance imaging (MRI) characteristics. Results: A total of 43 patients, 22 (51.2%) males and 21 (48.8%) females, were included in the study. There was a significant difference between pretreatment and post-treatment modified Rankin scale (mRS) scores (P 0.05); however, a significant decrease was found in the mRS scores of both groups with treatment (P < 0.05). The patients with abnormal MRI had significantly higher pretreatment mRS scores compared with the group with normal MRI (P < 0.05). Conclusions: This multicenter study demonstrated that first-line immunotherapy modalities (IVIg vs IVIg + steroids) had equal efficacy for the treatment of patients with CIDP. We also determined that MRI features might be associated with profound clinical features, but did not affect treatment response

Re-examining the characteristics of pediatric multiple sclerosis in the era of antibody-associated demyelinating syndromes.

Background: The discovery of anti-myelin oligodendrocyte glycoprotein (MOG)-IgG and anti-aquaporin 4 (AQP4)-IgG and the observation on certain patients previously diagnosed with multiple sclerosis (MS) actually have an antibody-mediated disease mandated re-evaluation of pediatric MS series. Aim: To describe the characteristics of recent pediatric MS cases by age groups and compare with the cohort established before 2015. Method: Data of pediatric MS patients diagnosed between 2015 and 2021 were collected from 44 pediatric neurology centers across Turkiye. Clinical and paraclinical features were compared between patients with dis-ease onset before 12 years (earlier onset) and >= 12 years (later onset) as well as between our current (2015-2021) and previous (< 2015) cohorts. Results: A total of 634 children (456 girls) were enrolled, 89 (14%) were of earlier onset. The earlier-onset group had lower female/male ratio, more frequent initial diagnosis of acute disseminated encephalomyelitis (ADEM), more frequent brainstem symptoms, longer interval between the first two attacks, less frequent spinal cord involvement on magnetic resonance imaging (MRI), and lower prevalence of cerebrospinal fluid (CSF)-restricted oligoclonal bands (OCBs). The earlier-onset group was less likely to respond to initial disease-modifying treatments. Compared to our previous cohort, the current series had fewer patients with onset < 12 years, initial presentation with ADEM-like features, brainstem or cerebellar symptoms, seizures, and spinal lesions on MRI. The female/male ratio, the frequency of sensorial symptoms, and CSF-restricted OCBs were higher than reported in our previous cohort. Conclusion: Pediatric MS starting before 12 years was less common than reported previously, likely due to exclusion of patients with antibody-mediated diseases. The results underline the importance of antibody testing and indicate pediatric MS may be a more homogeneous disorder and more similar to adult-onset MS than previously thought
