[Toxoplasmosis as a risk factor in pregnant women after renal transplantation]

Toxoplasmosis is an anthropo-zoonosis caused by the protozoa Toxoplasma gondii. The frequency of infection in the population of adults is estimated at 30-50%. Acquired toxoplasmosis takes a differentiated clinical course. It is usually symptomless or the symptoms are indistinct. In case of immunosuppressive treatment of the host severe Toxoplasma gondii infections can occur. There also is a possibility of transmission of the protozoa via transplant from the donor to the recipient as well as the possibility of reinfection of the acquired infection. In perinatal medicine toxoplasmosis plays a particularly important part due to the possibility of the transmission from mother to foetus. It seems therefore that women who are chronically treated with immunosuppressive eg after a renal transplant deserve special medical attention.
