High occurrence of HBV among STD clinic attenders in Bombay, India.

The pattern of sexually transmitted disease (STD) is the basis for designing surveillance of specific STD, their trends and syndromic management protocols. Two hundred and fifteen consecutive first-time STD clinic attenders at a teaching hospital in Bombay were recruited for the study in October 1995. Thorough clinical examination and the following investigations were done: wet mount, Gram stain, Giemsa stain, modified Thayer-Martin (MTM) medium culture, Fontana stain, Venereal Disease Research Laboratory (VDRL), Treponema pallidium haemagglutination test (TPHA), HBsAg and HIV. Ulcerative STD constituted 73.5% of total STD while 15.8% were discharges and 10.2% were genital growths. Ulcers in decreasing order of frequency were chancroid (51.9%), genital herpes (29.1%) and syphilis (14.5). 76.5% of genital discharges were due to gonococcal infection. The high rate of ulcerative STD is possibly an important co-factor for the high HIV prevalence of 31.2% in Bombay. Of 182 patients tested for HBV, 16 (8.8%) were reactive for HBsAg, revealing a high prevalence among STD attenders. A high co-relation of HBsAg positive with either HIV or VDRL requires urgent attention for HBV intervention strategies in this population.
