Immunoglobulin IgG, IgM, and IgA amounts normalized at 4 weeks of age, but IgG3 and IgG1 subclasses were reduced until six months of age. analysis showed a big change in the distribution of IgA concentrations compared to the normal ideals Rabbit polyclonal to CXCL10 (p<0.05), aswell as mean IgA (p<0.05) and IgM concentrations (p<0.05) based on the kind of immunosuppressive treatment of the mom (tacrolimus or cyclosporin treatment routine). == Conclusions == Evaluation of the sort of immunosuppressive therapy utilized during being pregnant revealed a feasible influence of the sort of calcineurin inhibitor on chosen parameters from the disease fighting capability of the kids; however, further study is required to confirm these results. MeSH Keywords:Kid, DISEASE FIGHTING CAPABILITY, Immunosuppressive Agents, Liver organ Transplantation, Being pregnant == History == Since the first successful transplantation in 1954, there has been a dynamic development of clinical transplantology and immunosuppressive therapy. In women, organ insufficiency preceding transplantation leads to menstrual disorders and infertility, but the level of medical knowledge now has increased the chance of these women to have children. Several months after transplantation, reproductive ability is restored [1]. The optimal time for conception after transplantation is 2 years, although some sources say that it is possible to shorten this time to 1 1 year [1]. The immunosuppressive agents most commonly used by patients after organ transplantation are tacrolimus, cyclosporine, azathioprine, glucocorticoids, mycophenolate mofetil, everolimus, H3B-6545 Hydrochloride and sirolimus. The main drugs used in the treatment regimens are calcineurin inhibitors: tacrolimus or cyclosporine [2]. Most of these drugs have been classified as Category C according to the FDA (Food and Drug Administration). These drugs pass through the H3B-6545 Hydrochloride placenta and can have a negative effect on the fetus, including lymphatic system damage, but the literature on this problem is still scarce [26]. The immune system evolved to protect the body against infections. Despite some differences among adults, children, and newborns, protection of the newborn against infection is sufficient if the mothers condition was good, the duration and the method of pregnancy termination were adequate, and the newborn was breastfed after delivery, but this rarely happens in children born to mothers after organ transplantation. One of the main tests that may be used to assess the immune system is serum immunoglobulin (IgG, IgM, IgA) levels [7]. Recurrent bacterial infections are manifestations of antibody deficiencies. In congenital immune deficiencies, infections typically occur between about 4 and 6 months of life, which is when maternal IgG disappears [8]. Slow physiological development of the immune system in children results in the normal values of immunoglobulin levels in the blood that vary depending on the age of the child [7]. == Aim == The aim of this study was to evaluate the effect of different types of immunosuppressive therapy on selected immune system parameters in children born to mothers after liver transplantation. == Material and Methods H3B-6545 Hydrochloride == The study group (LT) consisted of 52 children born to mothers after liver transplantation, aged between 1 and 10 years, born between December 2001 and July 2013, and examined in the period between December 2010 and July 2013, in the 1stDepartment of Obstetrics and Gynecology, Medical University of Warsaw. The control group involved 52 children born between March 2001 and July 2013, at similar gestational ages as the children in the study group, whose mothers consented to participate in the study. Immunosuppressive drugs used by mothers in the study group were tacrolimus, cyclosporine, glucocorticosteroid, and azathioprine. The characteristics of children in the study and control group included their age at the time of examination, gestational age, birth weight, and the type of termination of pregnancy (Table 1). == Table 1. == Characteristics of children from the study and control group. LT children born to mothers after liver transplantation; LT-control control group. All mothers of the examined children signed consent for participation in the study, and the study protocol was approved by the Bioethics Committee of the Medical University of Warsaw (KB/174/2009). The research funded by a grant (No. N N407 534938) from the Ministry of Science and Higher Education. To assess immunity, antibody IgG, IgM, and IgA levels were used. Venous blood samples were taken during a visit to the clinic. After clotting and centrifugation, immunoglobulin IgG, IgM, and IgA concentrations were determined by the immunoturbidimetric method on a Cobas 6000 (Roche) analyzer. The tests were done at the Central Laboratory of the Hospital of Baby Jesus in Warsaw. To evaluate antibodies, concentration reference values for immunoglobulin concentrations.
