Aim: Until now, the association between subepicardial adipose tissue (SAT), insulin resistance and intima-media thickness (IMT) has not been evaluated in obese children. In this study, we evaluated whether echocardiographic SAT is related to insulin resistance and IMT in obese children. Subjects and Methods: A total of 46 obese subjects (10.2 ± 2.5 years of age, 25 male patients) and 30 age-and gendermatched lean subjects (10.8±3.1 years of age, 13 male patients) were included in this study. The criterion for diagnosing obesity was defined as the body mass index (BMI) being over 97% percentile of the same gender and age. Serum triglyceride (TG), low-and high-density lipoprotein, cholesterol, glucose and insulin levels were measured during the fasting state. Each subject underwent a transthoracic echocardiogram and the SAT thickness was measured during end-diastole from the parasternal long-axis views. Results: The obese subjects had significantly higher SAT thickness and IMT values compared with the subjects in the control group (5.7±1.4 vs 3.0±0.7 mm, 0.78±0.15 vs 0.51±0.11 mm, P ¼ 0.001, respectively). Simple linear regression analysis showed no significant correlation between SAT and insulin resistance (r ¼ 0.170, P ¼ 0.253), whereas there was significant correlation between SAT and BMI, age and IMT (r ¼ 0.625, P ¼ 0.02, r ¼ 0.589, P ¼ 0.001, r ¼ 0.343, P ¼ 0.02, respectively). As an optimal cutoff point, a SAT thickness of 4.1 mm determined insulin resistance with 90% sensitivity and 61% specificity. Conclusions: Our study showed that SAT was significantly correlated with age, BMI and IMT, but not insulin resistance. However, our findings suggest that a 4.1 mm cutoff of SAT thickness might be used as a simple, inexpensive and non-invasive screening method because of its ability to predict insulin resistance with high sensitivity in obese children.
Rheumatic fever (RF) is an inflammatory disease caused by autoimmune response to a preceding group A streptococcal infection. Mean platelet volume (MPV) reflects the platelet size and the rate of platelet production in bone marrow, and it may be used as an indicator of platelet activation and severity of inflammation. Fifty-three consecutive patients diagnosed with acute rheumatic carditis and 53 control subjects were enrolled into this study. Leukocyte and platelet counts were significantly higher in patients with acute carditis before treatment compared with controls, whereas MPV and platelet distribution width (PDW) values were not significantly different between groups. Platelet counts, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) values were decreased significantly in patients with RF after treatment. There was not a significant difference in terms of platelet count between the controls and the patient group after treatment. ESR was found to be correlated with CRP in patients before and after treatment. In conclusion, the results of our study showed that MPV and PDW levels do not change during acute rheumatic carditis before and after treatment.
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 μg/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.
