[Demonstration of specific IgM antibody in cases of suspect congenital toxoplasmosis: interpretation of results (author's transl)]. 1976

H Werner, and C Schöning, and B Neuhaus, and I Maute

From the aspect of laboratory Toxoplasmosis examination, a series of clinically and parasitologically confirmed cases of congenital Toxoplasmosis (CT) were selected. Serological findings (CFT, DT, IgM-IFAT) in infants and mothers were critically examined. The IgM titers in CT as a rule lay between 1:16 and 1:64, the highest recorded being 1:256. The serum IgM globulin levels showed no dependence on the high CFT titers. T recognize unspecific reactions amongst infants with positive IgM values, the serological testing of mothers was indispensable. It is also absolutely necessary with infants to repeatedly test serologically at intervals to clearly bring out the results of all the three serological reactions. The technical problems encountered for a definative diagnosis of CT and the clinical picture in the present critical examination are discussed.

UI	MeSH Term	Description	Entries
D007075	Immunoglobulin M	A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin.	Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM
D007223	Infant	A child between 1 and 23 months of age.	Infants
D007231	Infant, Newborn	An infant during the first 28 days after birth.	Neonate,Newborns,Infants, Newborn,Neonates,Newborn,Newborn Infant,Newborn Infants

D003168	Complement Fixation Tests	Serologic tests based on inactivation of complement by the antigen-antibody complex (stage 1). Binding of free complement can be visualized by addition of a second antigen-antibody system such as red cells and appropriate red cell antibody (hemolysin) requiring complement for its completion (stage 2). Failure of the red cells to lyse indicates that a specific antigen-antibody reaction has taken place in stage 1. If red cells lyse, free complement is present indicating no antigen-antibody reaction occurred in stage 1.

D014125	Toxoplasmosis, Congenital	Prenatal protozoal infection with TOXOPLASMA gondii which is associated with injury to the developing fetal nervous system. The severity of this condition is related to the stage of pregnancy during which the infection occurs; first trimester infections are associated with a greater degree of neurologic dysfunction. Clinical features include HYDROCEPHALUS; MICROCEPHALY; deafness; cerebral calcifications; SEIZURES; and psychomotor retardation. Signs of a systemic infection may also be present at birth, including fever, rash, and hepatosplenomegaly.
