Demographic characteristics of patients presented to pediatric emergency department with febrile seizure and identification of risk factors for recurrence
Objective: Febrile convulsion is the most frequently observed type of convulsion in childhood. Our aim in this study is to identify etiological factors, risk factors for recurrence and recurrence rate by determining demographic characteristics of the patients with febrile convulsions
Transient proteinuria in an infant born to a mother with HELLP syndrome
The syndrome of haemolysis, elevated liver enzymes and low platelet count (HELLP syndrome) is a severe form of pre-eclampsia and eclampsia associated with poor maternal and neonatal outcome. We report here the case of an infant born to a mother with HELLP syndrome. The infant was initially diagnosed as having nephrotic syndrome but after a follow-up period of 25 days proteinuria and oedema had disappeared. Conclusion: to our knowledge, transient proteinuria with maternal HELLP syndrome has not been previously described in the literature
Antibody response to influenza A vaccination in children with nephrotic syndrome
The aim of this study was to determine the antibody response to influenza vaccination in children with nephrotic syndrome (NS). Nineteen children with NS and 10 healthy controls were vaccinated with a 19992000 influenza vaccine. A dose of 0.25 ml was used for those under 6 years and 0.5 ml for those over 6 years. All children were given two doses with a month between each dose. Antibody titers were measured before vaccination and 1 month after vaccination in both groups and 6 months after vaccination in 8 patients with NS. The proportion of subjects in the nephrotic group with protective antibody titers before immunization (10.5%) was significantly lower than the proportion at 1 (78.9%) and 6 months (87.5%) post vaccination. The mean concentration of specific IgG antibodies to influenza A in the NS group increased 6-fold at 1 month and approximately 14-fold at 6 months. These results suggest that pediatric patients with NS have an adequate antibody response to influenza A vaccine. Protective antibody titers to influenza A were maintained at 6 months after immunization in 8 patients with NS
Body mass index at the presentation of premature adrenarche is associated with components of metabolic syndrome at puberty.
The aim of this study was to analyze the relationship between premature adrenarche (PA) and metabolic syndrome (MeS) parameters at presentation and during puberty. This study comprised 47 girls with PA. Age- and puberty-matched 22 healthy girls without PA were the control group. Patients were evaluated at admission (first evaluation) and later in puberty (second evaluation). Anthropometric measurements, lipid levels, and hormonal parameters were studied and oral glucose tolerance test was performed. Indices for insulin resistance (IR) were calculated. The study group was divided in subgroups according to body mass index (BMI) and compared with the control group. The age of the PA group at first evaluation was 8.01.1years; mean height SDS and BMI SDS were 0.4 +/- 1.2 and 0.6 +/- 0.9, respectively. Age of PA group at the second evaluation was 12.9 +/- 2.4years. Frequency of obesity and overweight was 14.9 and 23.4%. Dyslipidemia ratio was 28.3%. PA group had significantly higher BMI than controls. Mean insulin concentration was higher and mean glucose and FGIR were lower in PA group and also dyslipidemia ratio was 5.3 times higher in PA than controls (p=0.040). In PA group, overweight/obese subjects had still higher BMI at second evaluation and also higher fasting glucose, insulin, HOMA-IR. However, PA children with exaggerated DHEAS concentrations compared to those without had similar BMI SDS, insulin sensitivity, and secretion indices and lipid profile at second evaluation. BMI SDS at first evaluation was positively correlated with HOMA-IR at puberty; however, there is no correlation between DHEAS at first evaluation and HOMA-IR at puberty.p id=Par Conclusion: BMI at adrenarche is more important than prepubertal adrogen concentrations such as DHEAS, while predicting the IR in puberty. Long-term follow-up of children supports the observation that PA per se may be related to IR; however, the risk increases with obesity
Effects of recombinant human erythropoietin on physiological inhibitors of coagulation in children on continuous ambulatory peritoneal dialysis
The effects of recombinant human erythropoietin (rHuEPO) on plasma and peritoneal effluent levels of antithrombin III (AT-III), protein C (PC) activity and protein S (PS) activity were evaluated in 10 uremic children or? continuous ambulatory peritoneal dialysis (CAPD). The findings were compared with values obtained from ten healthy children. Levels of AT-III and of PC and PS activity in plasma ar td peritoneal effluent were measured before, and at 8 and 12 weeks after; rHuEPO treatment. Baseline levels of AT-III and PC activity in plasma were lower than the control values. Levels of PC activity increased during the trial, while levels of AT-III remained unchanged, and levels of PS activity decreased. Baseline levels of PC activity in peritoneal effluent were lower than those obtained during rHuEPO treatment, while no change in peritoneal levels of PS activity and AT-III was observed after rHuEPO treatment. A significant positive correlation was seen between plasma and peritoneal levels of PC activity at baseline. A significant positive correlation was also seen between? plasma levels of PS activity and hemoglobin at week 12, and a significant negative correlation between plasma levels of AT-III and albumin at week 8. No correlation was found between the plasma natural coagulation inhibitors and CAPD duration. These results suggest that plasma PS activity cart be decreased, and plasma PC activity increased, by rHuEPO treatment in children
Effects of recombinant human erythropoietin on fibrinolytic system in children on continuous ambulatory peritoneal dialysis
We studied tissue plasminogen activator (t-PA) and plasminogen activator inhibitor 1 (PAI-1) levels in plasma and peritoneal effluent in 10 children on continuous ambulatory peritoneal dialysis (CAPD) before. and 8 and 12 weeks after; treatment with recombinant human erythropoietin (rHuEPO). Plasma t-PA and PAI-1 levels It ere lower in patients than in controls during the study The plasma t-PA levels were increased by rHuEPO treatment. Although PAI-1 levels showed a tendency to increase in the early phase of rHuEPO treatment, they later returned to near baseline levels. Peritoneal effluent t-PA levels were decreased at week 8 of treatment, but returned ro baseline levels at week 12. Peritoneal effluent PAI-1 levels were not changed by the rHuEPO treatment. No can-elation was observed between levels of t-PA and PAI-1 in plasma and in peritoneal effluent. No correlation was seen between plasma PAI-1 levels and duration of CA PD. A significant negative correlation was found between the plasma PAI-I levels and hemoglobin levels at week 8 and week 12. These results suggest that plasma t-PA levels can be increased by rHuEPO treatment, while plasma PAI-1 levels are associated with hemoglobin levels
Humoral immunity and frequency of peritonitis in chronic peritoneal dialysis patients
This study was designed to investigate the humoral immune status and immunological abnormalities in relation to the pathogenesis of peritonitis in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). The levels of serum and dialysate total protein, immunoglobulins (IgG, I-A, I-M, and IgG subgroups), and C3 were measured at baseline and at the end of the study in 12 children and 10 adult patients on CAPD. The relationship between the levels of immunoglobulin and C3 and the frequency of peritonitis was investigated. Peritonitis occurred at a frequency of one episode every 3.9 and 6.3 patient-months in children at the beginning and at the end of the study, respectively; however, the respective rates for adult patients were one episode every 5.6 and 9.8 patient-months. The levels of serum immunoglobulin and C3 were normal in adults at the beginning and at the end of the study. However, the levels of serum IgG were low in 4 of 12 pediatric patients. Of the 4 patients with low total IgG, I-A was low in I and IgM was low in 2 patients. Of 4 patients with low total IgG, 2 also had low IgG1 and IgG2. However, 3 of the patients with normal IgG had low IgG2 levels at the end of the study. The levels of C3 were low in 6 of 12 and in 3 of 10 pediatric patients at the beginning and at the end of the study, respectively. The protein levels of dialysate were increased at 1-year follow-up in both groups, but the difference was only statistically significant in adult patients (P<0.05). No correlation was found between the levels of serum and dialysate immunoglobulin and the frequency of peritonitis in either group. In this study, hypogammaglobulinemia and hypocomplementemia were determined in pediatric patients undergoing CAPD. Although these immunological deficits are not major factors in the occurrence of CAPD-related peritonitis, they may contribute to the frequency of peritonitis
