Both the humoral and cell mediated immunities are involved in the pathogenesis of JIA. It is reported that overall immunoglobulin levels in JIA patients are significantly higher than their control during the active state of disease. Methodology: This prospective observational study was conducted over a period of 18 months All the newly diagnosed oligo-articular and poly-articular JIA patients having active disease were included by purposive sampling. Data were collected by a semi-structured predesigned questionnaire. Result: Most of the study subjects (57.6%) belonged to age group > 3 - 9 years. Oligo JIA was diagnosed in 66.7% and poly JIA in 33.3% of JIA children. The difference in mean (±SD) ESR (33.52 ± 21.29 and 15.09 ± 7.71 mm in 1st hour) at active and inactive states was highly significant. Mean (±SD) difference of IgG, IgM and IgA in active and inactive states of disease were highly significant. Conclusion: Higher and abnormal levels of immunoglobulin (IgG, IgM, and IgA) were present among JIA patients in active disease state which became normal during inactive disease state after treatment.展开更多

文摘Hepatitis B virus(HBV)infection is a major public health burden.In HBV endemic regions,high prevalence is also correlated with the infections acquired in infancy through perinatal transmission or early childhood exposure to HBV,the socalled mother-to-child transmission(MTCT).Children who are infected with HBV at a young age are at higher risk of developing chronic HBV infection than those infected as adults,which may lead to worse clinical outcome.To reduce the incidence of HBV MTCT,several interventions for the infants or the mothers,or both,are already carried out.This review explores the newest information and approaches available in literature regarding HBV MTCT prevalence and its challenges,especially in high HBV endemic countries.This covers HBV screening in pregnant women,prenatal intervention,infant immunoprophylaxis,and postvaccination serological testing for children.
