Background: Pemphigus is an autoimmune bullous disease and it is unclear what triggers and deteriorates it. The current study aimed to evaluate whether increasing the IgG antibody titer represents a good indicator of the pemphigus recurrence. Objectives: The current study aimed to evaluate whether increasing IgG titer is an indicator of the expected recurrence. Patients and Methods: The current...

Newborn infants, especially preterm infants, have an immature immune system, which is not capable to actively protect against vaccine-preventable infections. Therefore, the newborn is dependent on transplacental transport of Immunoglobulin G (IgG), an active, FcRn receptor mediated process. Fetal IgG rises from approximately 10% of the maternal concentration at 17-22weeks of gestation to 50% at...

A clinical study of lyophilized intravenous human immunoglobulin containing high-titer cytomegalovirus-neutralizing antibody for the treatment cytomegalovirus viremia after allogeneic hematopoietic stem cell transplantation

BACKGROUND Whereas disease surveillance for infectious diseases such as rubella is important, it is critical to identify pregnant women at risk of passing rubella to their offspring, which can be fatal and can result in congenital rubella syndrome (CRS). The traditional centralized model for diagnosing rubella is cost-prohibitive in resource-limited settings, representing a major obstacle to th...

OBJECTIVE To compare antibody responses and side-effects of aerosolized and injected measles vaccines after revaccination of children enrolling in elementary schools. METHODS Vaccines for measles (Edmonston-Zagreb) or measles-rubella (Edmonston-Zagreb with RA27/3) were given by aerosol or injection to four groups of children. An additional group received Schwarz measles vaccine by injection. ...

BACKGROUND Probiotics have been shown to be immunomodulatory and can affect antibody responses following vaccination. Several immunisations are associated with suboptimal seroconversion rates leaving a substantial part of the population exposed to infection. OBJECTIVES To evaluate the influence of probiotic supplementation on the immune response of infants following mumps, measles, rubella an...

Kinetics of maternal rubella and varicella antibodies in 213 mother-infant pairs are described in a longitudinal study in Belgium. Blood samples are taken at 7 time points (week 36 of pregnancy, birth (cord), 1, 3, 6, 9, and 12 months), and analyzed for anti-rubella IgG and anti-varicella IgG by enzyme linked immunosorbent assay (ELISA). A generalized exponential model is used to analyse matern...

Background: Rubella infection with in the first trimester of pregnancy may lead to adverse pregnancy outcomes. The present study was conducted to evaluate the immunity against rubella among pregnant Iranian women. Materials and Methods: The steps of meta-analyses were conducted based on the PRISMA guidelines. To review the associated English and Persian literature, a comprehensive search was co...

Conventional serum antibody titer, which expresses level, does not provide antigen binding avidity of the variable region antibody, is essential for defense response to infection. Here, we quantified anti-SARS-CoV-2 receptor-binding domain (RBD) by competitive binding-inhibition activity (IC50) between SARS-CoV-2 S1 immobilized on DCP microarray and various RBD doses added expressed as 1/IC50 n...
