Who is at high risk? A comparison of the seroprevalence of human immunodeficiency virus in pregnant women and a high risk group

To compare the seroprevalence of HIV in Jamaican pregnant women with that in substance abusers, two groups of antenatal patients were studied, one (A) attending a public hospital clinic and the other (B) attending private clinics. The HIV seroprevalence in the antenatal patients was compared with that in the substance abusers, group C, in 1996 and five years later in 2001. HIV antibody was determined by enzyme immunoassay. The HIV seroprevalence in group A more than doubled (1.6-3.8) in five-years, 1996-2001. There were no seropositives in group B. In group C, the seroprevalence rose from 2.08 in 1996 to 5.76 in 2001. There was indication that group A might no longer be considered [quot ]low risk[quot ], as there was no significant difference from group C in HIV seroprevalence in 1996 and 2001. The trend seen in this study is worthy of further investigation

In vitro fertilization. The Jamaican experience

In June 2000, twenty-eight infertile couples were treated by in vitro fertilization and embryo transfer at our initial assisted reproduction programme carried out in conjunction with Midland Fertility Services, Aldridge, Birmingham, England. A pre-requisite for treatment was that on day 3 of the menstrual cycle the levels of follicle stimulating hormone (FSH) and oestradiol (E2) should be < 10 i mu/l and < 100 pg/ml respectively in the female partner. The ages of the women ranged from 26 to 42 years with a mean age of 35.5 years. Down regulation was carried out by using buserelin acetate 0.5 microgram subcutaneously from day 21 of the cycle for 21 days. This process was completed when the ovaries and pituitary gland were quiescent and the endometrial thickness < 4 mm in diameter. On completion of down regulation the gonadotrophin hormone, pergonal (dosage of 150-450 units) was used for ovarian hyperstimulation. A total of 294 oocytes (mean of 10.5, range 2-45) were retrieved of which 138 were fertilized (mean of 4.9, range of 0-28). Twenty-four patients each received a mean of two embryos. Five patients (20.8) had positive pregnancy tests. Three patients (0.1) developed ovarian hyperstimulation syndrome (OHSS), one had the severe, and two, the mild form of the syndrome. All three cases were treated successfully. The success at the initial IVF controlled ovarian hyperstimulation augers well for the future of infertile couples seeking treatment at the Fertility Management Unit, The University of the West Indies, Jamaica.

Prevalence of viral and bacterial sexually transmitted pathogens in Jamaican pregnant women

In this study we investigated the prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum, human immunodeficiency virus type I (HIV-I), human T cell lymphotropic virus type 1 (HTLV-1) and hepatitis B virus (HBV) infections in 200 pregnant women attending antenatal clinics at the University Hospital of the West Indies. 19of the women had at least one pathogen: C. trachomatis was found in 16, HTLV-1 in 2, HIV-1, HBV and N. gonorrhoeae each in 0.5C. trachomatis infection was more prevalent in women less than 20 years of age (31) than in those 20 years and older (16; OR = 0.43; chi 2 = 5.66; p < 0.05). The study demonstrates the need for identification of sexually transmitted pathogens in antenatal women for syndromic management of genital infections as part of the strategy for prevention and control of HIV/AIDS (acquired immunodeficiency syndrome) in Jamaica.
