Nowadays, there is a trend of HIV prevalence transmitting from high-risk group to average-risk group in China. Rural China is the weak link of HIV prevention, and rural areas of Henan province which is one of the most high-risk regions in China have more than 60% of the AIDS patients in the province. Thus, improving the HIV awareness and implementing health education become the top-priority of HIV/AIDS control and prevention. A multistage sampling was designed to draw 1129 people living with HIV/AIDS (PLWHAs) and 1168 non-PLWHAs in 4 prevalence counties of Henan province. A health promoting and social-psychological support model was constructed to improve the health knowledge of participants. Chi-square tests and unconditional logistic regression were performed to determine the intervention effect and influencing factors. All groups had misunderstandings towards the basic medical knowledge and the AIDS transmission mode. Before the intervention, 59.3% of the HIV/AIDS patients and 74.6% of the healthy people had negative attitudes towards the disease. There was statistically significant difference in the improvement of knowledge, attitude and action with regards to HIV prevention before and after intervention (P<0.05). PLWHAs who were males (OR=1.731) and had higher education level (OR=1.910) were found to have better HIV/AIDS health knowledge, whereas older PLWHAs (OR=0.961) were less likely to have better HIV/AIDS health knowledge. However, the intervention effect was associated with the expertise of doctors and supervisors, the content and methods of education, and participants' education level. It was concluded that health education of HIV/AIDS which positively influences the awareness and attitude of HIV prevention is popular in rural areas, therefore, a systematic and long-term program of HIV control and prevention is urgently needed in rural areas. © 2013 Huazhong University of Science and Technology and Springer-Verlag Berlin Heidelberg.

CD4 count is the standard method for determining eligibility for highly active antiretroviral therapy (HAART) and monitoring HIV/AIDS disease progression, but it is not widely available in resource-limited settings. This study examined the correlation between total lymphocyte count (TLC) and CD4 count of HIV-infected patients before and after HAART, and assessed the thresholds of TLC for making decisions about the initiation and for monitoring HAART. A retrospective study was performed, and 665 HIV-infected patients with TLC and CD4 count from four counties (Shangcai, Queshan, Shenqiu and Weishi) were included in the study. Pearson correlation and receiver operating characteristic (ROC) were used. TLC and CD4 count after HAART was significantly increased as compared with pre-HAART (P<0.01). An overall positive correlation was noted between TLC and CD4 count (pre-HAART, r=0.73, P=0.0001; follow-up HAART, r=0.56, P=0.0001). The ROC curve between TLC and CD4 count showed that TLC ≤ 1200 cells/mm3 could predict CD4 < 200 cells/mm3 with a sensitivity of 71.12%, specificity of 66.35% at pre-HAART. After 12-month HAART, the optimum prediction for CD4 count < 200 cells/mm3 was a TLC ≤ 1300 cells/mm3, with a sensitivity of 63.27%, and a specificity of 74.84%. Further finding indicated that TLC change was positively correlated to CD4 change (r=0.77, P=0.0001) at the time point of 12-month treatment, and the best prediction point of TLC change for CD4 increasing was 135 cells/mm3. TLC and its change can be used as a surrogate marker for CD4 count and its change of HIV-infected individuals for making decisions about the initiation and for monitoring HAART in resource-limited settings. © 2011 Huazhong University of Science and Technology and Springer-Verlag Berlin Heidelberg.

A retrospective study was conducted, and 576 human immunodeficiency virus-infected children with total lymphocyte count (TLC) and CD4 count were recruited from China. Spearman rank order correlation and receiver-operating characteristic were used. An overall positive correlation was noted between TLC and CD4 count (prehighly active antiretroviral therapy [pre-HAART], r = 0.789, 6 months of HAART, r = 0.642, 12 months of HAART, r = 0.691, P = 0.001). TLC ≤ 2600 cells/mm 3 predicted a CD4 count of ≤350 cells/mm 3 with 82.9% sensitivity, 79.6% specificity pre-HAART. Meanwhile, the optimum prediction for CD4 count of ≤350 cells/mm 3 was a TLC of ≤2400 cells/mm 3 at 6 months (73.6% sensitivity and 74.1% specificity) and 12 months (81.7% sensitivity and 76.5% specificity) of HAART. TLC can be used as a surrogate marker for predicting CD4 count of human immunodeficiency virus-infected children before and during HAART in resource-limited countries. © 2012 Lippincott Williams & Wilkins.
