Short course of systemic corticosteroids in wheezy children: still an open question

Introduction: We performed a real-life clinical study to identify the main indications for the prescription of short-course treatment with systemic glucocorticosteroids (GCS) for steroid naive children with acute virus-induced wheezing as well as to analyze the influence of such treatment on patients’ serum cortisol level, other blood tests results and the length of stay in the hospital.Material and methods: The data of 44 patients who had acute wheezing, had no bacterial infection and were otherwise healthy were analyzed: 26 children received treatment with GCS and 18 children did not. Full blood count, biochemistry tests (Na, K, glucose) and blood cortisol levels of all patients were analyzed during treatment.Results: The main indications for the short-term administration of systemic GCS were increased work of breathing, recurrent wheezing, clinical signs of atopy and a family history of asthma. Systemic GCS increased a sodium concentration (p = 0.014), decreased a cortisol level (p = 0.038), leukocyte (p = 0.043), neutrophil (p = 0.045), and eosinophil (p < 0.001) count in blood serum. The major reduction in the eosinophil count was observed in allergic children (p = 0.023). Older age was a risk factor for cortisol suppression (p = 0.018). The average length of stay in the hospital was longer in the intervention group (p = 0.039).Conclusion: Even short-course treatment with systemic GCS decreases the serum cortisol level and has a significant effect on other blood tests results. Systemic GCS used for acute virus-induced wheezing treatment did not prove to reduce the average length of stay in the hospital. Objective criteria for initiation of such treatment are still lacking, which might consequently lead to the overuse of corticosteroids

Induced mild hypothermia in children

The objective of this study was to measure outcomes and to determine the safety and effectiveness of mild induced hypothermia in children after traumatic and posthypoxic brain injury. Methods. Forty patients, following traumatic or posthypoxic brain injury, were involved in the study. Mean age was 10.7 ± 0.8 years. Median GCS (Glasgow Coma Scale) was 6.0 (4-7) and mean PIM2 (Pediatric Index of Mortality) 14.6 ± 3.8 %. Results. GOS (Glasgow Outcome Scale) of 5 was assigned for 15 (37.5%) patients, GOS 4 for 14 (35.0%), GOS 3 for 7 (17.5%) and GOS 2 for 4 (10%) patients. The average GOS in patients after severe head trauma was 3.6 ± 0.9 points and in patients with posthypoxic brain injury 5 points, (p < 0.05). No life threatening complications occurred. Conclusion. Mild induced hypothermia can be safely used in pediatric patents after severe traumatic or posthypoxic brain injury. This method may be of benefit while improving outcomes in children

A prognostic value of early urinary biomarkers NGAL and IL-18 in critically ill children: a 10-year literature review

Introduction. Acute kidney injury (AKI) is a life-threatening syndrome caused by a sudden and rapidly progressing impairment of renal function. It is a common and complicated clinical entity among hospitalized children, occurring in 2%-4.5% of children treated in a pediatric intensive care unit. Mortality among such patients remains high (from 8% to 89%) despite improving patient care and technical possibilities. Te stage of renal damage is a reversible process, and its timely detection would prevent the progression of renal damage and thus reduce pediatric mortality rates. Terefore, modern medicine necessitates the identifcation of novel AKI biomarkers that would correlate with renal cell damage and could be detected earlier than a rise in serum creatinine (sCr). Neutrophil gelatinase-associated lipocalin (NGAL) and interleukin 18 (IL-18) are one of such early markers of AKI. Aim. To carry out a literature review of studies on changes in NGAL and IL-18 levels in the urine of critically ill patients and to determine a prognostic value of these biomarkers in the detection of renal injury and impact on disease outcomes. Material and methods. Tis literature review includes the publications of biomedical studies assessing early biomarkers of AKI in urine (uNGAL or uIL-18) of critically ill children, published in English during the 10-year period. Search for publication was performed in the PubMed database. Results. Analysis included 10 studies that investigated early biomarkers of AKI(NGAL or IL-18) in urine of critically ill children and compared them with sCr. Among the biomedical studies analyzed in our literature review, 9 measured the NGAL level in urine or both in urine and serum, while 2measured IL-18 in urine. It was determined that uNGAL and uIL18 were good early diagnostic biomarkers of AKI, which increased 48 h earlier than Cr in serum (P<0.005). Te meta-analysis carried out by Haase et al. showed that uNGAL predicted the development of AKI better in critically ill children than in adults (OR, 25.4; ROC, 0.930 vs. OR, 10.6; ROC, 0.782). Tree studies reported that the uNGAL level in study populations with AKI directly depended on disease severity and AKI degree (P<0.005). Four studies found that uNGAL and one study that uIL18 are good predictive factors of mortality (P<0.005). Conclusions. uNGAL and uIL-18 are early predictive biomarkers of AKI in critically ill children. uNGAL and uIL-18 level correlated well with disease severity and are independent predictive biomarkers of mortality

One or two doses of live varicella virus-containing vaccines: Efficacy, persistence of immune responses, and safety six years after administration in healthy children during their second year of life

Abstract Background This phase III B follow-up of an initial multicenter study (NCT00226499) will evaluate the ten-year efficacy of two doses of the combined measles-mumps-rubella-varicella vaccine (MMRV) and one dose of the live attenuated varicella vaccine (V) versus a measles-mumps-rubella control group (MMR) for the prevention of clinical varicella disease. Here we present efficacy results for six years post-vaccination. Methods In phase A of the study, healthy children aged 12–22 months from ten European countries were randomized (3:3:1) and received either two doses of MMRV, or one dose of combined MMR and one dose of monovalent varicella vaccine (MMR+V), or two doses of the MMR vaccine (control), 42 days apart. Vaccine efficacy against all and against moderate or severe varicella (confirmed by detection of viral DNA or epidemiological link) was assessed from six weeks up to six years post-dose 2 for the MMRV and MMR+V groups, and was calculated with 95% confidence intervals (CI). The severity of varicella was calculated using the modified Vazquez scale (mild ≤ 7; moderately severe = 8–15; severe ≥ 16). Herpes zoster cases were also recorded. Results 5289 children (MMRV = 2279, mean age = 14.2, standard deviation [SD] = 2.5; MMR+V = 2266, mean age = 14.2, SD = 2.4; MMR = 744, mean age = 14.2, SD = 2.5 months) were included in the efficacy cohort. 815 varicella cases were confirmed. Efficacy of two doses of MMRV against all and against moderate or severe varicella was 95.0% (95% CI: 93.6–96.2) and 99.0% (95% CI: 97.7–99.6), respectively. Efficacy of one dose of varicella vaccine against all and against moderate or severe varicella was 67.0% (95% CI: 61.8–71.4) and 90.3% (95% CI: 86.9–92.8), respectively. There were four confirmed herpes zoster cases (MMR+V = 2, MMR = 2), all were mild and three tested positive for the wild-type virus. Conclusions Two doses of the MMRV vaccine and one dose of the varicella vaccine remain efficacious through six years post-vaccination

Heart Rate Variability and Atria Function in Children at Late Follow-Up Evaluation After Atrioventricular Node Slow-Pathway Radiofrequency Ablation

This study was designed to assess the changes in the conductive system, autonomic dysfunction, and global and regional function of the atria and ventricles in children late after slow-pathway radiofrequency ablation (RFA). The study enrolled 22 children, who has successfully undergone RFA 2 to 5 years previously (RFA group) and 20 healthy children (control group). Electrophysiologic study was performed for the RFA group. Holter monitoring and echocardiography were performed for all the children. At a late follow-up assessment, the RFA children were free of paroxysms, whereas 8 of the 22 children (36%) reported transient palpitations. Both mean and maximal heart rates (HR) were significantly increased, whereas indices of HR variability (% of succesive normal sinus RR intervals exceeding 50 ms [pNN50], root mean square of the succesive normal sinus RR interval difference [rMSSD], high-frequency component [HFC]) were significantly decreased in the RFA group compared with preablation and control data. Left atrial (LA) and right atrial (RA) volumes were significantly higher, and atria deformation indices were significantly lower in the RFA group. Correlations were found between the mean HR and the volumes of LA (r = 0.477; p < 0.001) and RA (r = 0.512; p < 0.001). A negative correlation between the maximal LA volume and the longitudinal strain rate (SR) during relaxation (r = –0.476; p = 0.03) and a positive correlation between the minimal LA volume and both longitudinal SR (r = 0.361; p = 0.03) and strain (ε) (r = 0.375; p = 0.024) during contraction were shown. These data suggest a possible link between atrial dysfunction and the hyperadrenergic state after RFA

T-cell-based diagnosis of tuberculosis infection in children in Lithuania: a country of high incidence despite a high coverage with bacille Calmette-Guerin vaccination

<p>Abstract</p> <p>Background</p> <p>Lithuania is a country with a high incidence of tuberculosis (TB), despite a high coverage with bacille Calmette-Guerin (BCG) vaccination. Until now the only method used to detect latent TB infection was the tuberculin skin test (TST). However, TST may have a cross reactivity to the BCG vaccine and to environmental mycobacteria. The aim of this study was to conduct assessments of the diagnostic accuracy of the T-cell based test (T SPOT TB) for TB in children who had previously been BCG vaccinated and compare these with the results of the TST.</p> <p>Methods</p> <p>Between January 2005 and February 2007, children with bacteriologically confirmed TB, children having contacts with a case of infectious pulmonary TB and children without any known risk for TB were tested with both the TST and T SPOT TB.</p> <p>Results</p> <p>The TST and T SPOT TB tests were positive for all patients in the „culture-confirmed TB“ group. Whereas, in the „high risk for TB“ group, the TST was positive for 60%, but the T SPOT TB test, only for 17.8%. Meanwhile the results for the „low risk for TB“ group were 65.4% and 9.6%, respectively. A correlation between the TST and T SPOT TB was obtained in the "culture-confirmed TB" group where the TST ≥15 mm (r = 0.35, p < 0.001).</p> <p>Conclusion</p> <p>The T-cell based method is more objective than the TST for identifying latent TB infection in children who had been previously BCG vaccinated. This method could be useful in countries like Lithuania where there is a high incidence of TB despite a high coverage with BCG vaccination. It may also help to avoid unnecessary chemoprophylaxis when TST reactions are false-positive.</p

The Impact of Tobacco Smoke Exposure on Wheezing and Overweight in 4–6-Year-Old Children

eISSN: 2314-6141. Article ID 240757Aim. To investigate the association between maternal smoking during pregnancy, second-hand tobacco smoke (STS) exposure, education level, and preschool children's wheezing and overweight. Methods. This cohort study used data of the KANC cohort—1,489 4–6-year-old children from Kaunas city, Lithuania. Multivariate logistic regression was employed to study the influence of prenatal and postnatal STS exposure on the prevalence of wheezing and overweight, controlling for potential confounders. Results. Children exposed to maternal smoking during pregnancy had a slightly increased prevalence of wheezing and overweight. Postnatal exposure to STS was associated with a statistically significantly increased risk of wheezing and overweight in children born to mothers with lower education levels (OR 2.12; 95% CI 1.04–4.35 and 3.57; 95% CI 1.76–7.21, accordingly). Conclusions. The present study findings suggest that both maternal smoking during pregnancy and STS increase the risk of childhood wheezing and overweight, whereas lower maternal education might have a synergetic effect.
