A prospective long-term evaluation of the ocular findings of children followed with the diagnosis of multisystem inflammatory syndrome (long-term evaluation of ocular findings following MIS-C)

Background/Objectives: The most frequently reported ocular finding in the acute phase of the multisystem inflammatory syndrome in children (MIS-C), is conjunctivitis. More rarely, punctuate epitheliopathy, anterior uveitis and optic disc oedema can be seen. We aimed to investigate the acute and long-term ocular effects of MIS-C. Subjects/Methods: Cases aged 1 month to 18 years who were diagnosed with MIS-C between January 2022 and June 2022 in the Department of Pediatric Infectious Diseases in our hospital were included in the study. Ophthalmological examinations were performed immediately after diagnosis, at one month, three months, and six months. Results: Males consisted of 64.7% of the 34 cases included in the study and the mean age was 8.68 ± 4.32 years (min-max:2–17). In the first examination, conjunctivitis was observed in 6 (17.6%), punctuate epitheliopathy in 4 (11.7%), and subconjunctival haemorrhage in 3 (8.8%) patients. Two patients (5.8%) had optic disc oedema. No pathological anterior or posterior segment findings were observed in the sixth-month examination. The relationship between subconjunctival haemorrhage and intensive care hospitalisation was statistically significant (p = 0.014). Also, all patients with subconjunctival haemorrhage were clinically classified as severe MIS-C (p = 0.002). Conclusion: Although pathological ocular findings were observed in the acute phase of the disease, all of them were found to be improved at the sixth-month follow-up. The most striking finding of our study is that cases with subconjunctival haemorrhage were clinically more severe, and all patients needed intensive care. This study may be informative in establishing ocular follow-up protocols that are expected to be carried out in the acute period and in the follow-up of these patients

Parental Attitudes About Lumbar Puncture in Children With Suspected Central Nervous System Infection

Objectives This study aimed to evaluate parents' attitudes toward lumbar puncture (LP) for their children with suspected central nervous system infection to determine the reasons for rejection and related factors. Methods The survey was provided to parents of children (1 month to 18 years old) for whom LP was recommended because of a concern for central nervous system infection. Sociodemographic characteristics and other related factors of parents who did and did not approve of LP were compared statistically. The reasons for the disapproval of parents who refused LP were revealed. Results A total of 100 parents were included in the study. Eighty-two percent of the participating parents were mothers, and the median age of the mothers was 31 years (min: 17 years; max: 70 years). The median age of the fathers was 37 years (min: 22 years; max: 60 years). Among the parents, 34% did not give consent for LP. The most common reason for the participants to refuse LP was fear of paralysis of their children due to the procedure (82.3%). There was a statistical difference between the approval of the LP procedure and the person who informed the parents about the LP procedure and read the informed consent form (P = 0.004 and P = 0.038, respectively). As a result of the binary logistic regression analysis, it was seen that the rate of acceptance of the LP procedure by the parents informed by the specialist doctors was 7.1-fold (P = 0.02; 95% confidence interval, 1.3-37.6) higher than the parents informed by the resident physicians. Conclusion The informed consent process mainly influenced parents' attitudes toward LP. To increase the acceptance rates of LP, we should standardize the informed consent process so that it is not affected by factors such as seniority of the physician

Multisystem inflammatory syndrome in children associated with COVID-19 in 101 cases from Turkey (Turk-MISC study)

Aim Multisystem inflammatory syndrome in children (MIS-C) may cause shock and even death in children. The aim of this study is to describe the clinical features, laboratory characteristics and outcome of children diagnosed with MIS-C in 25 different hospitals in Turkey. Methods The retrospective study was conducted between 8 April and 28 October 2020 in 25 different hospitals from 17 cities. Data were collected from patients' medical records using a standardised form. Clinical and laboratory characteristics and outcomes according to different age groups, gender and body mass index percentiles were compared using multivariate logistic regression analysis. Results The study comprised 101 patients, median age 7 years (interquartile range (IQR) 4.6-9.3); 51 (50.5%) were boys. Reverse-transcriptase polymerase chain reaction (PCR) assay was positive in 21/100 (21%) patients; 62/83 (74.6%) patients had positive serology for SARS-CoV-2. The predominant complaints were fever (100%), fatigue (n = 90, 89.1%), and gastrointestinal symptoms (n = 81, 80.2%). Serum C-reactive protein (in 101 patients, median 165 mg/L; range 112-228), erythrocyte sedimentation rate (73/84, median 53 mm/s; IQR 30-84) and procalcitonin levels (86/89, median 5 mu g/L; IQR 0.58-20.2) were elevated. Thirty-eight patients (37.6%) required admission to intensive care. Kawasaki disease (KD) was diagnosed in 70 (69.3%) patients, 40 of whom had classical KD. Most patients were treated with intravenous immunoglobulin (n = 92, 91%) and glucocorticoids (n = 59, 58.4%). Seven patients (6.9%) died. Conclusion The clinical spectrum of MIS-C is broad, but clinicians should consider MIS-C in the differential diagnosis when persistent fever, fatigue and gastrointestinal symptoms are prominent. Most patients diagnosed with MIS-C were previously healthy. Immunomodulatory treatment and supportive intensive care are important in the management of cases with MIS-C. Glucocorticoids and intravenous immunoglobulins are the most common immunomodulatory treatment options for MIS-C. Prompt diagnosis and prompt treatment are essential for optimal management

Serum Amyloid A Levels and Severity of COVID-19 in Children

Objective: The aim of this study was to determine the availability of serum amyloid A (SAA) in the diagnosis of coronavirus disease 2019 (COVID-19), to asses disease severity and to predict hospitalization status. Methods: Between March, 2020 and March, 2021, a total of 80 children (40 cases with COVID-19 and 40 cases in healthy group) were included in this study. Patients were divided into two groups (mild and moderate/severe) to evaluate SAA levels in terms of clinical severity and also hospitalization status. Results: Comparisons between the two groups revealed that median SAA values were significantly higher in children with COVID-19 than in their healthy peers (21.45vs3.05 mg/L, P=0.002). There was no significant difference in the median serum SAA levels between mild and moderate/severe clinical disease (P=0.837). The SAA difference between the two groups with regards to hospitalization was not statistically significant (P=0.098). Conclusions: Although SAA level was found to be higher in children with COVID 19 compared to healthy controls, the sensitivity of SAA for the disease was found to be low. In addition, there was no difference between the groups in terms of clinical severity

Influenza is more severe than our newest enemy (COVID-19) in hospitalized children: Experience from a tertiary center

Understanding differences in terms of clinical phenotypes and outcomes of coronavirus disease 2019 (COVID-19) compared with influenza is vital to optimizing the management of patients and planning healthcare. Herein, we aimed to investigate the clinical differences and outcomes in hospitalized patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza. We performed a retrospective study of hospitalized children who were positive for SARS-CoV-2 between March 2020 and March 2021 and for influenza between January 2016 and February 2020 in respiratory samples. The primary outcome of this study was pediatric intensive care unit (PICU) admission, and the secondary outcome was the need for respiratory support. A total of 74 patients with influenza and 71 who were positive for SARS-CoV-2 were included. The distribution among the sexes was similar, but patients with COVID-19 were older than patients with influenza (96 vs. 12, p < 0.001). In terms of underlying chronic diseases, the frequency was 26.7% in the COVID-19 group and 54% in the influenza group (p = 0.001). The comparison of symptoms revealed that fatigue, headache, nausea, vomiting, and abdominal pain occurred more frequently with COVID-19 (for all p < 0.05) and runny nose with influenza (p = 0.002). The frequency of admission to the PICU was relatively higher (18.9%) in the influenza group than with COVID-19 (2.8%) with a significant ratio (p = 0.001), secondary bacterial infections were observed more frequently in the influenza group (20.2% vs. 4.2%, p = 0.003). Some 88.7% of patients with COVID-19 did not need respiratory support, whereas 59.4% of patients with influenza did require respiratory support (p < 0.001). This study noted that influenza caused more frequent admissions to the PICU and a greater need for respiratory support in hospitalized pediatric patients than COVID-19

The diversity in the clinical features of children hospitalized with COVID-19 during the nonvariant, Alpha (B.1.1.7), Delta (B.1.617.2), and Omicron (B.1.1.529) variant periods of SARS CoV-2: Caution for neurological symptoms in Omicron variant

Since the COVID-19 pandemic began, various severe acute respiratory syndrome coronavirus 2 variants have been identified with different characteristics than the nonvariant strain. We retrospectively evaluated the demographic and clinical differences in the cohort of hospitalized COVID-19 children (1 month–18 years old) between March 11, 2020, and September 31, 2022, by the time the variants identified in our country predominate. Bonferroni post hoc analysis was performed to compare the differences between the periods. Of the 283 children in this study, 142 (50.2%) were females. The median age was 36 (interquartile range [IQR]: 7–132) months. Sixty-three (22.2%) patients were hospitalized in the nonvariant period, 24 (8.5%) in the Alpha period, 93 (32.9%) in the Delta period, and 103 (36.4%) in the Omicron period. Fever was the most common symptom in all groups, with no statistically significant differences (p = 0.25). In the Omicron period, respiratory and gastrointestinal symptoms decreased, and neurological symptoms increased significantly compared to other periods: [respiratory symptoms; nonvariant (65.1%) vs. Omicron (41.7%), (p = 0.024)], [gastrointestinal symptoms; Delta (41.9%) vs. Omicron (22.3%), (p = 0.018), [neurological symptoms; Delta (14.5%) vs. Omicron (31.1%), (p = 0.03]. Altered mental status and seizures were more common during the Omicron period compared to the pre-Omicron (nonvariant, Alpha, and Delta) period (p = 0.017 and p = 0.005, respectively). Although the main symptoms in children with COVID-19 were fever and respiratory symptoms, an increase in severe neurological manifestations was seen throughout the Omicron variant period

Does the Thymus Index Predict COVID-19 Severity?

BACKGROUND: The COVID-19 (coronavirus disease 2019) pandemic is a global health emergency that is straining health care resources. Identifying patients likely to experience severe illness would allow more targeted use of resources. This study aimed to investigate the association between the thymus index (TI) on thorax computed tomography (CT) and prognosis in patients with COVID-19. METHODS: A multicenter, cross-sectional, retrospective study was conducted between March 17 and June 30, 2020, in patients with confirmed COVID-19. The patients' clinical history and laboratory data were collected after receiving a signed consent form. Four experienced radiologists who were blinded to each other and patient data performed image evaluation. The appearance of the thymus was assessed in each patient using 2 published systems, including the TI and thymic morphology. Exclusion criteria were lack of initial diagnostic thoracic CT, previous sternotomy, pregnancy, and inappropriate images for thymic evaluation. A total of 2588 patients with confirmed COVID-19 and 1231 of these with appropriate thoracic CT imaging were included. Multivariable analysis was performed to predict the risk of severe disease and mortality. RESULTS: The median age was 45 (interquartile range, 33-58) years; 52.2% were male. Two hundred forty-nine (20.2%) patients had severe disease, and 60 (4.9%) patients died. Thymus index was significantly associated with mortality and severe disease (odds ratios, 0.289 [95% confidence interval, 0.141-0.588; P = 0.001]; and 0.266 [95% confidence interval, 0.075-0.932; P = 0.038]), respectively. Perithymic lymphadenopathy on CT imaging had a significantly strong association with grades of TI in patients with severe disease and death ( V = 0.413 P = 0.017; and V = 0.261 P = 0.002, respectively). A morphologically assessable thymus increased the probability of survival by 17-fold and the absence of severe disease by 12-fold. CONCLUSION: Assessment of the thymus in patients with COVID-19 may provide useful prognostic data for both disease severity and mortality

Evaluation of Attitudes and Knowledge of Influenza Diagnosis, Treatment and Vaccination Among Pediatric Residents

Objective: Influenza virus is common in children, especially in winter, causing hospitalization, admission to the intensive care unit, or even death. There are few studies on the attitudes or knowledge of influenza diagnosis, treatment, and vaccination among pediatricians. This study was planned to determine pediatric residents' attitudes and behaviors about recognizing the influenza virus, making treatment decisions, prophylaxis, and immunization
