RESUMO

PURPOSE: The present study investigates the long-term effects of intravenous immunoglobulin (IVIg) therapy for the treatment of moderate to severe childhood atopic dermatitis (AD). Previous research indicates that IVIg can treat severe AD; however, the effectiveness of IVIg has not been confirmed in prospective, blinded clinical trials. METHODS: Forty eligible children with moderate to severe AD, as defined by the criteria of Hanifin and Rajka, were enrolled in a randomized, placebo-controlled study. After the completion of an initial screening visit (V0), the patients were randomly allocated into therapy (n=30) and control (n=10) groups (V1). Thirty children were each treated with three injections of 2.0 g/kg IVIg at 1-month intervals over a 12-week period. Ten children were treated with placebo. Assessments were conducted after each injection (V2, V3, and V4) and at 3 (V5) and 6 months (V6) after completed treatment. RESULTS: The disease severity index was significantly decreased at V5 compared with the value at V1 (P<0.05). There were no significant changes in the total IgE level or total eosinophil count in peripheral blood at the last injection (V4) compared with the value at V1. The interleukin (IL)-5/interferon (IFN)-gamma ratio was assessed in T-helper 1 (Th1) and Th2 cells. The ratio significantly decreased between V1 and V5, after which it increased, such that the ratio at V6 was not significantly different from that at V1. Compared with the level at V1, the intercellular cell adhesion molecule-1 level at V4 did not differ significantly, but the level at V5 was lower. CONCLUSIONS: This study suggests that IVIg therapy may clinically improve AD in patients after 3 months of therapy, but the improvement may decline by 6 months after therapy.

RESUMO

BACKGROUND/AIMS: Nonalcoholic steatohepatitis (NASH) is the progressive form of non-alcoholic fatty liver disease (NAFLD), and its prevalence is increasing worldwide. Liver biopsy remains the best way to diagnose NASH and establish the presence of fibrosis, but has not been performed easily in children because of its invasiveness. We analyzed the ultrasonographic and histopathologic findings of pediatric NAFLD patients, and studied to find their association with clinical characteristics and laboratory findings. METHODS: The study involved 18 obese children ranging from 7 to 15 years of age, who were diagnosed with NASH by liver biopsy. We performed the abdomen ultrasonography before the liver biopsy. We reviewed their pathology slides and classified them by NASH CRN (Clinical Research Network) scoring system. We also reviewed the abdomen ultrasonographic findings of the patients and classified them into grade of 1, 2, and 3. We reviewed the medical records of the patients and investigated their clinical characteristics and laboratory findings. RESULTS: The ultrasonographic grades had significant association with NAFLD activity score, grade of steatosis amount, ballooning change, and portal inflammation. Serum triglyceride level was significantly higher in patients who showed high grade steatosis and high NAFLD activity score. CONCLUSIONS: This study showed that serum triglycerides and ultrasonographic findings are highly correlated with pathologic findings in children with NAFLD.
