BACKGROUND: congenital infections are associated with a wide variety of clinical symptoms, including small for gestational age (SGA).
AIMS: to determine the co-occurrence of SGA and congenital TORCH infections, as diagnosed by TORCH serologic tests and/or cytomegalovirus (CMV) urine culture.
STUDY DESIGN: we performed a retrospective study of all neonates admitted to our neonatal intensive care unit from January 2004 to February 2010 in whom SGA was diagnosed and TORCH serologic tests and/or CMV urine cultures were performed.
RESULTS: TORCH serologic tests (in neonatal or maternal serum) and/or a CMV urine culture were performed in 112 neonates with SGA. None of the neonates tested positive for Toxoplasma gondii, Rubella, and Herpes simplex virus. Positive CMV urine culture was detected in 2% (2/112) of neonates, but their CMV IgM titers were negative.
CONCLUSIONS: the co-occurrence of TORCH congenital infection in infants with SGA is rare. Routine TORCH screening in neonates with isolated SGA does not seem warranted and should be limited to CMV urine cultures.
