Objective To investigate mother-to-child transmission of HIV-1 and the factors that affect transmission. Methods 136 children who were born to HIV positive mothers in a high HIV prevalence region were interviewed and blood samples were examined for anti-HIV anti-HGV and HIV RNA or HIV DNA. Results Among 136 children who were born to HIV positive mothers, 50 were infected with HIV. The MTCT rate was 36.8% (50/136). Thirty eight DNA fragments of HIV-1 gag gene P17 obtained from HIV-1 seropositive mothers were amplified by PCR from uncultured peripheral blood mononuclear cells (PBMCs). Sequence analyses showed that all of them were HIV-1 B subtype. The HIV vertical transmission rate among mothers with AIDS (67.4%, 31/46) was significantly greater than among those with HIV alone (21.1%, 19/90), P

Objection To investigate the spectrum and survival status of HIV positive cancer in HuBei province, China. Methods HIV positive cancer patients were added up and followed up who had registered in Zhongnan Hospital between January 2004 and June 2009. The prognostic features were determined for HIV patients with cancer. Results The average age of HIV positive and HIV negative group who suffered with malignant neoplasm were 42.5±8.8 years and 55.1±13.7 years respectively (P <0.05), mean CD4 counts were (220.9±142.3)/μl and (554.4±174.3)/μl, respectively (P <0.05), the types of common cancer were NHL, cervical cancer, liver cancer and lung cancer, colon cancer, breast cancer, respectively. Anticancer and/or ART treatment were the important positive prognostic factors. Additional factors such as age and CD4 count were associated with survival of cancer patients with HIV infection. Conclusion Mean age of HIV positive cancer patients is about 42 years old. NHL, cervical cancer and liver cancer are HIV associated malignant tumor. ART and anticancer can effectively prolong the survival of HIV infected patients with cancer.

Objective To evaluate the therapeutic effects of antiretroviral therapy(ART)on human immunedeficiency virus (HIV)-1-infected children. Methods Twenty-two HIV-1-infected children who met World Health Organization (WHO) criteria for treatment received ART and were prospectively enrolled in this study. ART contained two kinds of nucleoside reverse transcriptase inhibitor (NRTI) combined with one kind of non-nucleoside reverse transcriptase inhibitor (NNRTI).Before ART and 1-36 months after ART, height, body weight, blood routine, peripheral CD4+ and CD8+ T cell counts and plasma viral load were followed up regularly. Comparison between groups was done by test. Results Among the 22 pediatric AIDS patients, 19 cases (86.4%) achieved clinical improve, whose height and body weight increased significantly 6 months after ART (height = 1 :1.04±0. 02, t=2. 356, P<0. 05; body weight= 1: 1. 14±0. 01,t=2. 567,P< 0. 05) and opportunistic infection rate decreased (72.7 % vs. 27.3 %) ; 3 patients (13.6 % ) deteriorated, whose height and body weight increased slowly and even decreased, 2 of them died. In the 19 improved patients, viral load declined to <2.7 lg copy/mL at month 3 of ART, CD4+ T cell counts and CD4+/CD8+ ratio significantly increased at month 3 of ART (CD4+ T cell counts: 145.50±86.72 vs. 262.80±213.62,t=2. 668, P<0.05; CD4+/CD8+ ratio: 0. 14±0. 11 vs. 0.23±0. 21,t=2. 607, P<0. 05) and CD4+/CD8+ ratio peaked at month 9 and absolute number of CD4+ T cell counts peaked at month 12 and maintained at high level until month 36, peripheral white blood cells (WBC) and red blood cells (RBC) both decreased, while hemoglobin (Hb) contents increased significantly (107.29 ± 13.74 vs. 112. 15±11.20,t=2. 325,P<0. 05). Conclusion ART is an effective strategy for inhibition of HIV-1 replication,reconstruction of immune responses and improvement of clinical symptoms in AIDS children.
