Preliminary Report on HIV-1 Vaccine Preparedness in Nigeria: Advantages of Recruiting University Students
The national HIV seroprevalence in Nigeria has risen steeply from about 3% in 1993 to 5–8% in 2001 and now stands at 4.4%. HIV epidemic continues to be a serious threat to the most populous country in Africa with a population of 140 million, with limited use of antiviral drugs that is taken for life since it only suppresses the virus without completely eliminating the virus or leading to cure. Only a change in social behavior and an affordable vaccine can halt the epidemic in Africa. We report here results of a pilot study on the recruitment strategies, sociodemographic aspects and HIV risk behavior of a cohort of normal volunteers recruited at the University of Jos, Nigeria. Our study recorded a high degree of interest and zeal to participate in HIV vaccine studies by volunteers, and demonstrated the superiority of snowballing over invitation by mail, as a recruitment strategy. A cohort of university students may be particularly suitable for conducting HIV vaccine trials because of the assurance of prospective follow-up for up to four years (time to graduation), and a good understanding of the risks and benefits of participation as outlined in the informed consent. We had 100% retention during a follow-up period of two years. Most importantly, the cohort reflected a relatively low HIV seroprevalence, which gives preventive programs the potential to blunt or halt the epidemic

Reference Values of CD4 T Lymphocytes in Human Immunodeficiency Virus-Negative Adult Nigerians
A cross-sectional study that involved secondary analysis of data collected from 681 pregnant women and 183 miners (94 men and 89 women; ratio of men to women, 1:0.95) in Jos, Nigeria, was carried out to determine the reference ranges for CD4(+)-cell counts in healthy HIV-negative adult Nigerians. The main results of interest were CD4(+)-cell counts and odds ratios (ORs) of low CD4(+)-cell counts, defined as below 350 cells per μl. CD4(+)-cell counts were similar in men and nonpregnant women, with a mean (standard deviation) of 828 (203) cells per μl, but pregnant women had a lower value of 771 (250) cells per μl. None of the factors assessed was related to the odds of having a low CD4(+)-cell count among men and nonpregnant women, but age, age of marriage, and alcohol usage were significant predictors in pregnant women. Compared to pregnant women less than 20 years old, older women had significantly lower odds of a low CD4(+)-cell count (ORs were 0.06 for women aged 20 to 29 years and 0.22 for those aged 30 to 39 years). When compared with those pregnant women who were married before 20 years of age, those who married at 20 to 29 years and 30 to 39 years had odds ratios of 6.41 and 9.40, respectively. Previous alcohol use was also associated with low CD4(+)-cell counts (OR, 5.15). The 95% confidence interval for CD4(+)-cell counts in healthy adult Nigerians is 547 to 1,327 cells per μl, and this is the first time this has been determined
