It is used in cases of previous loss, high maternal titers, known aggressive antibodies, and in cases where religion prevents blood transfusion. IVIG can be more effective than IUT alone. Fetal mortality was reduced by 36% in the IVIG and IUT group than in the IUT alone group. IVIG and plasmapheresis together can reduce or eliminate the need for an IUT. Plasmapheresis – Plasmapheresis aims to decrease the maternal titer by direct plasma replacement and physical removal of antibody. Plasmapheresis and IVIG together can even be used on women with previously hydropic fetuses and fetal losses.Mid- to late- pregnancy

IUT – Intrauterine Transfusion (IUT) is done either by intraperitoneal transfusion (IPT) or intravenous transfusion (IVT). IVT is preferred over IPT. IUTs are only done until 35 weeks. After that, the risk of an IUT is greater than the risk from post birth transfusion. Steroids – Steroids are sometimes given to the mother before IUTs and early delivery to mature the fetal lungs. Phenobarbital – Phenobarbital is sometimes given to the mother to help mature the fetal liver and reduce hyperbilirubinemia. Early Delivery – Delivery can occur anytime after the age of viability. Emergency delivery due to failed IUT is possible, along with induction of labor at 35–38 weeks.Rhesus-negative mothers who are pregnant with a rhesus-positive infant are offered Rho(D) immune globulin (RhIG, or RhoGam) at 28 weeks during pregnancy, at 34 weeks, and within 48 hours after delivery to prevent sensitization to the D antigen.
Chromosomal translocation and extra chromosomes help create abnormally high activity of certain proto-oncogenes, which caused by these genetic abnormalities and include those encoding c-myc, HRAS, and vav. The activity of proto-oncogenes is not the only cellular function that is affected; tumour suppressor genes are affected by the chromosomal changes induced by mycoplasma, as well. Partial or complete loss of chromosomes causes the loss of important genes involved in the regulation of cell proliferation. Two genes whose activities are markedly decreased during chronic infections with mycoplasma are the Rb and the p53 tumour suppressor genes. Another possible mechanism of carcinogenesis is RAC1 activation by a small GTPase-like protein fragment of Mycoplasma. A major feature that differentiates mycoplasmas from other carcinogenic pathogens is that the mycoplasmas do not cause the cellular changes by insertion of their own genetic material into the host cell. The exact mechanism by which the bacterium causes the changes is not yet known. Partial reversibility of malignant transformationsThe malignant transformation induced by Mycoplasma species is also different from that caused by other pathogens in that the process is reversible. The state of reversal is, however, only possible up to a certain point during the infection. The window of time when reversibility is possible varies greatly; it depends primarily on the Mycoplasma involved. In the case of M. fermentans, the transformation is reversible until around week 11 of infection and starts to become irreversible between weeks 11 and 18. If the bacteria are killed using antibiotics (i.e.
