ABSTRACTWith continuing occurrence of varicella despite increasing vaccine coverage for the past 20 years, a case-based study, a case-control study, and an immunogenicity and safety study were conducted to address the impact of varicella vaccination in South Korea. Varicella patients under the age of 16 years were enrolled for the case-based study. For the case-control study, varicella patients between 12 months and 15 years of age were enrolled with one control matched for each patient. For the immunogenicity and safety study, otherwise healthy children from 12 to 24 months old were immunized with Suduvax (Green Cross, South Korea). Fluorescent antibody to membrane antigen (FAMA) varicella-zoster virus (VZV) antibody was measured before and 6 weeks after immunization. In the case-based study, the median age of the patients was 4 years. Among 152 patients between 1 and 15 years of age, 139 children received varicella vaccine and all had breakthrough infections. Clinical courses were not ameliorated in vaccinated patients, but more vaccinated patients received outpatient rather than inpatient care. In the case-control study, the adjusted overall effectiveness of varicella vaccination was 54%. In the immunogenicity and safety study, the seroconversion rate and geometric mean titer for FAMA antibody were 76.67% and 5.31. Even with increasing varicella vaccine uptake, we illustrate no upward age shift in the peak incidence, a high proportion of breakthrough disease, almost no amelioration in disease presentation by vaccination, and insufficient immunogenicity of domestic varicella vaccine. There is need to improve the varicella vaccine used in South Korea.

ObjectiveKawasaki disease (KD) is an acute form of febrile vasculitis that occurs in early childhood. The multisystemic vasculitis common in patients with KD may influence blood perfusion in the brain, and thus caregivers of children with KD may feel stress with regard to caring for them. Intravenous immunoglobulin (IVIG) infusion is the standard treatment for acute KD, and the most serious complication of KD is coronary artery aneurysms (coronary artery lesion (CAL)). This study aimed to investigate the relationships between KD heterogeneity and the risk of patients’ cognitive impairment or caregivers’ parenting stress.DesignA case–control study with consecutive sampling.SettingA medical centre (Kaohsiung Chang Gung Memorial Hospital, Taiwan).ParticipantsThis study consisted of 176 patients with KD (mean age: 5.5 years, 60.8% boys) and 85 healthy children (mean age: 6.4 years, 54.1% boys).Primary and secondary outcome measuresBased on the children’s age, each patient with KD and control subject was administered an assessment using the Mullen Scales of Early Learning or the Wechsler Intelligence Scale, and parenting function of their caregivers was assessed using the Parenting Stress Index (PSI)-Short Form.ResultsWe observed no significant differences in any developmental index, cognitive function or parenting stress between patients with KD and controls. Among the children with KD, IVIG administration nor CAL was associated with children’s cognitive scores. However, the caregivers of patients who had CAL suffered from greater PSI total scores than those of patients without CAL. Furthermore, the caregivers who had education levels of a master’s degree or above showed less parenting stress than those who had an education level of college or lower.ConclusionCaregivers’ education is associated to parenting stress, and caregivers of patients with KD who developed CAL may feel stress about the unpredictable sequela caused by CAL for their children. Such caregivers may require support to fulfil their parenting roles.

Kawasaki disease (KD) is the most common cause of pediatric acquired heart disease. KD patients have spontaneously high plasma/serum levels of IL-10 during the acute phase. Therefore, two independent studies were carried out to investigate the association between genetic variants in IL-10 promoter (−1082, −819, and −592) and risk of KD. A total of 134 trios were included for the family-based association study. A significantly preferential transmission of the C allele at loci −819 T > C and −592 A > C for KD cases was observed (Ppermutation= 0.029 and Ppermutation= 0.034, respectively). There was a significant increase in the transmission of haplotype CC (p= 0.016) at the above two loci (OR, 1.632; 95% CI, 1.090–2.443; Ppermutation= 0.019). We also carried out a follow-up case-control study that included 146 KD cases and 315 unrelated healthy children. {The haplotype CC (−819, −592) showed an increased risk of KD (but statistically non-significant; OR, 1.332; 95% CI, 0.987–1.797;p= 0.061). In diplotype analysis, a trend was found between number of CC haplotype and risk of KD (but non-significant,p= 0.061). In conclusion, CC genotype and CC/CC diplotype at IL-10-819T > C and −592A > C were significantly associated with risk of KD in case-parent trio study, which were replicated partially in our follow-up case-control study.

A temperature-related seizure is a febrile seizure that affects the QT interval. The purpose of this study was to evaluate the changes in the QT interval caused by febrile convulsion compared with healthy children. Method This case-control study considered the distribution of 180 children equally shared between patients and controls. The study was conducted at the "Ali Ebne Abi Talib" Hospital in Zahedan, Iran. The disease diagnosed and confirmed based on standard definitions of febrile convulsion. QT interval measured by ECG and interpreted by a pediatric cardiologist and collected data were analyzed with SPSS 19 considering 0.05 as significant error. Results Among the ECG parameters, HR, R in aVL, S in V3, LVM, QTd, QTc and QTcd were significantly different in children with febrile convulsion compared to the peers. From those who had abnormal QTd, FC children were more frequented but not significant (CHI SQUARE=1.053, p=0.248), when children with FC were more in abnormality regarding QTc (CHI SQUARE=13.032, p<0.001) and QTcd (CHI SQUARE=21.6, P<0.001) significantly. In children with FC, those who were aged less than 12 months, had the highest level of HR but not significant (CHI SQUARE=4.59, p=0.101). Similar trends occurred for R in aVL and S in V3 that were higher in the age group >24 months (p>0.05). LVM had the highest value in the age group of >24 months significantly (CHI SQUARE= 52.674, P<0.001) and the other QT parameters were same in Fc children with different age groups (P>0.05). Conclusion From the study concluded that dispersion corrected QT, corrected QT and dispersion QT changed significantly in children with febrile convulsion in comparing with the healthy children but with constant values in children with FC in different age groups.

Abstract Background: Lipoprotein(a) [Lp(a)] is a plasma lipoprotein that has been implicated in both atherogenesis and thrombophilia. A few reports in recent years, principally in European populations, have suggested that elevated plasma Lp(a) level may constitute a risk factor for ischemic arterial stroke (IAS) in children. However, the ELISA assays used in these studies are technically limited by their ability to provide accurate Lp(a) values independently of apo(a) size. Objective: To determine the prevalence of elevated plasma Lp(a) concentration among children with non-neonatal IAS and healthy children in a U.S. population using the current gold-standard laboratory methodology, toward the evaluation of Lp(a) as a risk factor for pediatric IAS. Methods: In a case-control study, children from 1 month to 21 years of age with a history of radiologically-confirmed IAS (case group, n=22) and healthy children (contemporaneous control group, n=41) were consecutively recruited from The Children’s Hospital, Denver, and the Mountain States Regional Hemophilia and Thrombosis Center (Aurora, CO). Children with IAS who were receiving drugs that affect Lp(a) level, such as niacin or statins, were excluded. Fasting plasma samples were obtained by peripheral venipuncture into EDTA with susequent centrifugation to yield platelet-poor plasma. Lp(a) assay was performed in the Northwest Lipid Metabolism and Diabetes Research Laboratories at the University of Washington, Seattle, using a double monoclonal antibody-based ELISA validated to be sensitive to apo(a) size heterogeneity. Results were expressed in nmol/L of Lp(a) protein, with corresponding race-appropriate percentiles. In accordance with NHLBI recommendations, values above the 75th percentile were considered to indicate increased risk, and were hence designated as elevated. Results: Median Lp(a) concentration did not significantly differ between the two groups (cases: 16.9 nmol/L, controls: 24.7 nmol/L; P=0.96). While the prevalence of elevated Lp(a) levels was increased among children with IAS (cases: 36%, controls: 24%), this difference did not reach statistical significance (P=0.32). The odds of having elevated Lp(a) were nearly two times that of healthy controls (OR=1.8, 95% CI=0.50–6.3); however, this also was not statistically significant. Conclusions: The present study demonstrates a qualitatively increased prevalence of elevated plasma Lp(a) concentration among children with non-neonatal IAS when compared to healthy children, using the gold-standard methodology for Lp(a) assessment. Expansion of the study to a larger population via multicenter collaboration will be necessary to definitively determine whether Lp(a) is a risk factor for IAS in children. Furthermore, given that genetic variation in the apo(a) gene is the major determinant of plasma Lp(a) concentration, apo(a) phenotyping may be useful to better define risk strata. These efforts are an important precursor to interventional studies evaluating Lp(a) management strategies in the secondary prevention of IAS in children.

Objective Acute organ embolism in children with Mycoplasma pneumoniae pneumonia (MPP) has been reported, but changes in coagulation are unclear. This study aimed to investigate changes in coagulation in children with MPP. Methods A total of 185 children with MMP (cases) and 117 healthy children (controls) were recruited. We measured prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), and plasma fibrinogen (FIB) and D-dimer levels. Results Plasma FIB (3.39 ± 0.96 g/L vs 2.93 ± 0.6 6g/L, t = 4.50) and D-dimer (326.45 ± 95.62mg/L vs 263.93 ± 103.32mg/L, t=5.36) in MPP children were higher than controls and PT (9.54 ± 4.97S vs 11.48 ± 5.96S, t=3.05) and APTT (31.41 ± 12.01S vs 38.38 ± 11.72S, t=4.95) were shorter than controls. FIB, D-dimer, PT, and APTT were not different between the high IgM-titre and low-titre groups. The areas under the receiver operating characteristic curves in cases and controls for plasma FIB and D-dimer levels were 0.654 (95% confidence interval [CI], 0.593–0.716, P = 0.031) and 0.682 (95% CI, 0.619–0.744, P = 0.032), respectively. Conclusions Children with MPP have a higher risk of blood coagulation and thrombosis. Controlling these problems should be considered as soon as possible.

Abstract Introduction The clinical complications of congenital hypothyroidism such as brain disorders are very subtle and are not recognizable in infancy period. They are recognizable when it is too late for treatment or prevention. General screening of newborns is effective in diagnosing congenital hypothyroidism and initiating initial treatment. The aim of this study is to compare the physical and mental growth pattern of children with congenital hypothyroidism with healthy ones. Methods This case–control study was performed on 34 patients and 68 healthy children who were matched in terms of inclusion and exclusion criteria. Children development screening test (ASQ), children development assessment test (Bayley), preschool Wechsler intelligence scale (WPPSI) and age and steps questionnaire of emotional social development (ASQ-SE) were completed by trained questioners. Data were analyzed using STATA software. Results The results indicated that there was no significant difference between the mean of verbal (P = 0.77), non-verbal (P = 0.81) and general (P = 0.66) IQ in permanent and transient patients and healthy individuals. Also, there was no significant difference between the mean of different ranges of ASQ test (including communication, delicate and large movements, problem solving and social) at 12 months and 42 months (P < 0.05). According to Bayley test, there was no significant difference between the cases (permanent and transient) and controls in the cognitive (P = 0.42) and expressive (P = 0.38) categories. The difference was significant in the perceptual (P = 0.011), large (P = 0.03) and delicate (P = 0.04) movements categories. Conclusion This study emphasized on the high effectiveness of neonate hypothyroidism screening program, so that the difference between 3.5 years old children with and without this disease has decreased significantly. Early diagnosis of the patients, while creating beneficial effects for patients and increasing quality of life, cause reduction in the long-term costs of the health system.
