Congenital toxoplasmosis Congenital cytomegalovirus (CMV) Use of certain drugs during pregnancy, especially alcohol and phenytoin Becoming infected with the Zika virus while pregnant can also cause microcephaly. Congenital infections are caused by pathogens transmitted from mother to child during pregnancy (transplacentally) or delivery (peripartum). (14 to 85%) develop chorioretinitis, strabismus, blindness, hydrocephalus or microcephaly, cerebral calcifications, developmental delay, epilepsy, or deafness months or years later. 57 Clinical manifestations of congenital toxoplasmosis consist of retinochoroiditis, hydrocephalus, microcephaly, cerebral calcifications, seizures, psychomotor retardation, organomegaly, jaundice, rash, and fever. The acronym TORCH stands for the causative pathogens of congenital infections: Toxoplasma gondii , others (including Treponema pallidum On the contrary, in the newborn, congenital toxoplasmosis can be responsible of hydrocephalus, microcephaly, intracranial calcifications, strabismus, blindness, epilepsy, mental retardation, thrombocytopenia, anemia and chorioretinitis. When there is bilateral involvement, 29% of the eyes have visual acuity worse than 20/40. The presence of chorioretinitis, intracranial calcifications, and hydrocephalus is considered the classic triad of congenital toxoplasmosis. However, infants with congenital toxoplasmosis have been born to immunocompetent women with prior histories of toxoplasmosis infection and with evidence of prior immunity (38).This can occur when a previously-infected pregnant mother is reinfected with a new and more virulent strain. 11). Congenital toxoplasmosis is a disease that occurs in fetuses infected with Toxoplasma gondii, a protozoan parasite, which is transmitted from mother to fetus.It can cause miscarriage or . Exposure to Toxoplasma is common, and in most children and adults, a Toxoplasma infection is harmless. Other causes of microcephaly, including severe microcephaly, can include the following exposures during pregnancy: Certain infections during pregnancy, such as rubella, toxoplasmosis, or cytomegalovirus Congenital toxoplasmosis is the consequence of transplacental hematogenous fetal infection by T gondii during primary infection in pregnant women. Microcephaly is a condition where a baby has a head size much smaller compared with other babies of the same age and sex. , others (including. About 10% of infants with congenital CMV infection will have health problems at birth, which include: Rash. Other problems that may lead to microcephaly include: Uncontrolled phenylketonuria (PKU) in the mother; Methylmercury poisoning; Congenital rubella; Congenital toxoplasmosis; Congenital cytomegalovirus (CMV) Use of certain drugs during pregnancy, especially alcohol and phenytoin; Becoming infected with the Zika virus while pregnant can also . Toxoplasmosis! Microcephaly is a head size (measured as the distance around the top of the head) significantly below the median for the infant's age and sex. Additional clinical tips: Always calculate the percentile of HC considering sex and gestational age. Clinical manifestations of congenital toxoplasmosis are different. The Toxoplasma parasite can live in cat feces (poop), water, soil, or certain foods. Infection with T gondii before pregnancy confers little or no risk to the fetus except in women who become infected up to 3 months before conception. Microcephaly (my-kroh-SEF-uh-lee) is a rare neurological condition in which an infant's head is significantly smaller than the heads of other children of the same age and sex. Toxoplasmosis does not usually give any symptoms to a pregnant woman and in most cases she does not realize to be infected. Primary infection in an otherwise healthy pregnant woman is asymptomatic in 60% of cases. Clinical findings in patients with congenital toxoplasmosis may include: chorioretinitis and other ocular findings, central nervous system abnormalities (such as microcephaly, hydrocephalus, encephalomyelitis, seizures and mental retardation), icterus, hepatosplenomegaly, rash . Congenital toxoplasmosis can have severe sequelae, including mental retardation, blindness, and epilepsy in infancy or much later in life. In addition to microcephaly, children with these intrauterine infections often have other abnormal clinical findings which can include . Microcephaly can be present at birth (congenital) or may develop postnatally (acquired). Congenital toxoplasmosis happens when a pregnant mother infected with Toxoplasma passes the parasite to the baby during pregnancy. Fig. The Zika virus is present in Brazil and other parts of South America, along with Mexico, Central America, and the Caribbean. The Toxoplasma parasite can live in cat feces (poop), water, soil, or certain foods. Congenital toxoplasmosis is a disease that occurs in fetuses infected with Toxoplasma gondii, a protozoan parasite, which is transmitted from mother to fetus. 9, 10 In the neonate, manifestations of congenital toxoplasmosis might include hydrocephalus, microcephaly, intracranial calcifications, retinochoroiditis, strabismus, blindness, epilepsy, psychomotor and mental retardation . The emergence of Zika-virus-associated congenital microcephaly has engendered renewed interest in the pathogenesis of microcephaly induced by infectious agents. It can cause miscarriage or. Newborns with microcephaly are more likely to be tested for congenital CMV than newborns without microcephaly, as are newborns with sensorineural hearing loss (SNHL) who fail the newborn hearing screen (or have other congenital CMV-related symptoms). Congenital toxoplasmosis is almost exclusively due to a primary maternal infection during pregnancy; however, there are exceptions, including reinfection with a new serotype of T. gondii or reactivation of toxoplasmosis in mothers with severe cell-mediated immunodeficiencies. Congenital Zika syndrome includes these five birth defects: Severe microcephaly with a partly collapsed skull. Head size is an important measurement to monitor a child's brain growth. Microcephaly is a birth defect in which a baby's head is smaller than expected, compared to babies of the same sex and age. Congenital toxoplasmosis happens when a pregnant mother infected with Toxoplasma passes the parasite to the baby during pregnancy. Congenital toxoplasmosis Author: Dr Elisabeth Robert-Gnansia1,2 Creation date: October 2003 1member of Editorial Committee of Orphanet Encyclopedia 2 Institut Européen des Génomutations, 86 Rue du docteur Edmond Locard, 69005 Lyon, France. Objective: Toxoplasmosis, cytomegalovirus (CMV), and Zika virus (ZIKV) are among the common infectious agents that may infect the fetuses vertically. Other causes may include: Craniosynostosis. Some babies have microcephaly because of changes in their genes. Congenital microcephaly may occur as an isolated structural birth defect or in combination with other birth defects. Microcephaly is a condition where a baby's head is much smaller than expected. However, his serological tests for congenital infections, including . The emergence of Zika-virus-associated congenital microcephaly has engendered renewed interest in the pathogenesis of microcephaly induced by infectious agents. It most often occurs because of failure of the . Congenital toxoplasmosis. They can have a substantial negative impact on fetal and neonatal health. Microcephaly has been associated with intellectual disability . The premature fusing of the joints (sutures) between the bony plates that form an infant's skull keeps the brain from growing. The severity of microcephaly ranges from mild to severe. Diagnosis - serology - IgM +ve, or IgG rise (or IgA +ve or low IgG avidity)! Congenital toxoplasmosis must be . Microcephaly may be genetic. Congenital toxoplasmosis can have severe sequelae, including mental retardation, blindness, and epilepsy in infancy or much later in life. Manifestations, if present, are prematurity, intrauterine growth restriction, jaundice, hepatosplenomegaly, myocarditis, pneumonitis, rash, chorioretinitis, hydrocephalus, intracranial calcifications, microcephaly, and seizures. Congenital toxoplasmosis. Significantly below is generally considered to be smaller than three standard deviations below the mean, or less than 42 cm in circumference at full growth. Sometimes detected at birth, microcephaly usually is the result of the brain developing abnormally in the womb or not growing as it should after birth. . 11.

Three of the original "TORCH" agents are associated with an appreciable incidence of congenital microcephaly: cytomegalovirus, rubella virus, and Toxoplasma gondii. Teratogenic conditions with microcephaly include congenital rubella, CMV, congenital Zika infection and congenital toxoplasmosis. Treatment Congenital toxoplasmosis has a wide spectrum of clinical manifestations, but it is subclinical in approximately 75% of infected newborns. What you need to know •Fetal microcephaly can be isolated or be associated with other congenital anomalies •Causes include genetic, chromosomal, infections, exposure to toxins (such as alcohol), metabolic, intrauterine growth restriction, or a normal variant The 2022 edition of ICD-10-CM P37.1 became effective on October 1, 2021. Three of the original "TORCH" agents are associated with an appreciable incidence of congenital microcephaly: cytomegalovirus, rubella virus, and Toxoplasma gondii. Toxoplasmosis had been suspected, but the treatment was withheld because of only a slightly elevated maternal Toxoplasma specific immunoglobulin M (IgM) antibody, 1.4 index by enzyme linked immnosorbent assay (ELISA) and a borderline IgG avidity index, 50% at 28 weeks . Exposure to Toxoplasma is common, and in most children and adults, a Toxoplasma infection is harmless. The size of the cranial vault is an indicator of the size of the underlying brain.

At 20 weeks pregnant, microcephaly had been detected by ultrasonography. elisabeth.robert@ieg.asso.fr Abstract Key words Disease name Environmental factors that are teratogenic must also be included in the differential diagnosis as common etiologies. Congenital Anomalies of the Nervous System: Microcephaly. Introduction: Microcephaly is a congenital anomaly associated with a wide range of etiological factors such as infections, medications/substances, genetic abnormalities and radiation. Involvement of the CNS is a hallmark of congenital Toxoplasmainfection. Family physicians may be confronted with a number of . Congenital infections causing microcephaly are known as TORCH infections (Toxoplasmosis, Other infections (Syphilis, Varicella Zoster, Parvovirus B-19), Rubella, Cytomegalovirus (CMV) and Herpes virus). Congenital toxoplasmosis is caused by transplacental acquisition of Toxoplasma gondii. Jaundice (yellowing of the skin or whites of the eyes) Microcephaly (small head) Low birth weight. The 2022 edition of ICD-10-CM P37.1 became effective on October 1, 2021. The causes of microcephaly in most babies are unknown. Microcephaly can occur because a baby's brain has not developed properly during pregnancy or has stopped growing after birth, which results in a smaller head size. • Most common congenital viral infection - Prevalence of congenital CMV infection of 0.48 - 1.3% • Symptoms: microcephaly, ventriculomeg, chorioretinitis, jaundice, HSM, thrombocytopenia, and petechiae • "Symptomatic" = infants with ≥ 1 symptoms at birth - High risk of epilepsy, delays, CP, vision loss, SNHL Congenital toxoplasmosis typically results from acquired infection in nonimmune women.
