Study Notes
TORCH Infections Overview
- TORCH refers to a group of infections transmitted from mother to fetus, primarily during pregnancy.
- Key pathogens include Toxoplasma gondii, Rubella, Cytomegalovirus, HIV, Herpes simplex virus-2, and Syphilis.
Toxoplasma gondii
- Transmission via cat feces or ingestion of undercooked meat.
- Usually asymptomatic in the mother, with rare cases exhibiting lymphadenopathy.
- Neonatal impact includes a classic triad: chorioretinitis, hydrocephalus, and intracranial calcifications. Possible "blueberry muffin" rash.
Rubella
- Transmitted through respiratory droplets.
- Maternal symptoms may present as rash, lymphadenopathy, polyarthritis, and polyarthralgia.
- In infants, classic triad includes eye abnormalities (cataracts), ear anomalies (deafness), and congenital heart disease (patent ductus arteriosus). "Blueberry muffin" rash may also be observed.
Cytomegalovirus
- Spread through sexual contact and organ transplants.
- Often asymptomatic during pregnancy; some may experience mononucleosis-like symptoms.
- Neonatal findings can include hearing loss, seizures, petechial rash, "blueberry muffin" rash, and chorioretinitis.
HIV
- Transmitted via sexual contact or needlestick injuries.
- Maternal symptoms vary significantly based on CD4+ T cell count.
- Neonatal outcomes may involve recurrent infections, chronic diarrhea, and meningoencephalitis.
Herpes Simplex Virus-2
- Spread through skin or mucous membrane contact.
- Typically asymptomatic in mothers, may present with herpetic vesicular lesions.
- Infected neonates may show herpetic lesions, potentially leading to stillbirth or hydrops fetalis.
Syphilis
- Two primary stages of infection: primary chancre and secondary disseminated rash. These stages can lead to fetal infection.
- Surviving infants may display facial abnormalities (e.g., notched teeth, saddle nose), saber shins, and CN VIII deafness.
Additional Infections
- Other significant pathogens that may affect neonates include:
- Streptococcus agalactiae - group B streptococci linked to meningitis.
- E. coli - also a common cause of neonatal meningitis.
- Listeria monocytogenes - associated with severe outcomes in neonates.
- Parvovirus B19 - known to cause hydrops fetalis.
Common Neonatal Signs
- Nonspecific signs such as hepatosplenomegaly, jaundice, thrombocytopenia, and growth restriction can occur among multiple TORCH infections.
