Dear Editor,

Occurrence of congenital syphilis reflects a failure of antenatal care delivery systems. Recently reports from many developed nations have observed a spurt in the incidence of syphilis.[1] Diagnosis of congenital syphilis is problematic since more than half of all infants are asymptomatic at birth and the treatment delay can lead to irreversible sequelae.

A newborn male whose mother was a confirmed case of syphilis had Venereal Disease Research Laboratory (VDRL) (Institute of Serology, Calcutta, India) reactivity titre of 1:8 at birth and 1:16 at day 3 of life. Further the diagnosis was confirmed using Treponema pallidum haemagglutination assay (TPHA) (Plasmatec, Bridport Dorset, U.K). The biochemical and cytological results of cerebrospinal fluid (CSF) were within normal limits. CSF VDRL was non-reactive. X-ray showed normal bony skeleton. The baby apparently appeared normal. The mother had history of painless genital ulcer 2 years back and reactive VDRL test during pregnancy. She was advised benzathine penicillin, though it was not received by her. She was again tested at the time of delivery. The VDRL titre was significant (1:16). Father was a healthcare worker and tested reactive to VDRL (titre 1:32) and positive for TPHA. Newborn was given crystalline penicillin for 10 days and parents were administered 3 doses of 1.2 million units benzathine penicillin weekly.

The treatment response was monitored after 2½ months. The child was reactive to VDRL in serum without dilution, and the parents were reactive to VDRL in 1:2 dilutions showing a significant response to treatment. All of them tested positive for TPHA (1:640) and negative for HIV by serological methods.

This case highlights that despite education and awareness there can be such cases in the community. Though there is an overall decrease in seroprevalence of syphilis in India,[2],[3],[4] occurrence of these cases do challenge the on-going control programmes.
