The study was conducted on 32 HIV positive patients (24 males and 8 females, over 15 years old, with CD4 T-cell counts <350 cell/mm3) who were treated with antiretrovirus therapy (Videx and Zerit) at Dong Da Hospital from Nov 2002 to Oct 2003. The results showed that ARV therapy is effective. The weight, Kanofsky scores, and T CD4 counts of patients were increased significantly after 6 months of treatment. Side effects included fatigue, headache, nausea, but only on first week. Enzyme amylase was increased slightly after 6 months of treatment

OBJECTIVE: To determine the prevalence of otorhinolaryngologic (ENT) manifestations in people living with Human Immunodeficiency Virus (HIV) infection seen in our institutions and to determine the association of these manifestations with age, sex, CD4 count and antiretroviral treatment.

METHODS:
Study Design: Cross-sectional study

Setting: Two Tertiary Government Hospitals

Subjects: Adult patients (>19 years old) confirmed to be HIV- infected  were seen at Jose R. Reyes Memorial Medical Center and San Lazaro Hospital from February to July 2014. A data sheet regarding ENT manifestations was filled upon examination. Age, sex, CD4 count and antiretroviral treatment data were recorded. Independent samples t-test was used to determine age association with manifestations. Fischer's exact test was used to determine association of sex and manifestations. Chi-square test of independence was used to determine association of CD4 count and antiretroviral treatment with manifestations. Association was considered statistically significant if p< 0.05.

RESULTS: Three hundred one (301) patients participated with 287 males (95.3%) and 14 females (4.7%). The mean age was 31.7 ± 8. One hundred ninety seven (197 or 65.4%) had ENT manifestations. The most common areas of manifestations came from the oral cavity-oropharyngeal area (n=104, 37%), nasal cavity-nasopharyngeal area (n=73, 26%) and ear (n=43, 15%). The most frequent manifestations were cervical lymphadenopathy, aphthous stomatitis and acute rhinitis. There was no significant difference in the age (p=0.31) and sex (p=0.15) of patients with and without manifestations. However, there was a direct association of manifestations with low CD4 count (p<0.001) and inverse association with antiretroviral treatment (p=0.036).

CONCLUSION: Our findings emphasize the importance of screening for ENT manifestations, regular CD4 monitoring and enrollment to antiretroviral therapy in persons with HIV. Baseline otorhinolaryngologic examination upon HIV diagnosis and prior to initiating treatment should be followed by regular surveillance. Conversely, physicians should also be aware that patients with ENT manifestation may have HIV infection.

BACKGROUNDThis study was aim to explore the characteristics of phenotypic resistance of resistant strains of HIV type-1 (HIV-1) subtype B and to compare the concordance between the phenotypic resistance and genotypic resistance.

METHODSThe genotypic resistance assay for the HIV-1 clinical isolates was performed. One isolate without resistance mutation was chosen as a drug-sensitive reference strain and seven subtype B isolates with resistance mutations were phenotypically tested. Fifty percent inhibitory concentrations (IC50) between resistant and sensitive viruses were compared. The resistance extent was determined by the folds of the increased IC50. The concordance between the phenotypic resistance and genotypic resistance was also analyzed.

RESULTSIC50 of resistant isolates were 0.0006 - 0.1300 micromol/L for zidovudine (AZT), 0.0016 - 0.0390 micromol/L for lamivudine (3TC), 0.0104 - 0.4234 micromol/L for nevirapine (NVP), and 0.0163 - 0.1142 micromol/L for indinavir (IDV), respectively. Genotypic and phenotypic resistance assays indicated that the resistant strains were intermediately and highly resistant to nucleotide analog reverse transcriptase inhibitors and non-nucleotide analog reverse transcriptase inhibitors. The phenotypic assay was consistent with the genotypic assay. For measuring the potential resistance, the genotypic assay was more sensitive than the phenotypic. In evaluating the resistance to protease inhibitors, these two assays were discrepant.

CONCLUSIONSBoth the phenotypic and genotypic assays indicate that the resistant viruses exist in HIV-infected patients in China who have received treatment. Phenotypic and genotypic assays have high concordance, and the genotypic assay could replace the phenotypic assay to predict the HIV-1 resistance.

OBJECTIVETo analyze the key indicators of China Comprehensive AIDS Response Program (China CARES) and the effects of this program during 2008 and 2011.

METHODSData were obtained from National AIDS Comprehensive Prevention and Control Information System. The general population HIV test rate and spouse of people living with HIV or AIDS (PLWHA) HIV test rate were chosen as the indicators for HIV testing expansion; anti-retroviral therapy (ART) coverage and PLWHA CD4 test rate during the past 6 months as the indicators for treatment expansion; femal sex worker (FSW) intervention coverage and injection drug users (IDU) intervention coverage as the Indicators for behavior intervention expansion. The Key working quality indicators of 309 program sites were calculated and the results were compared.

RESULTSDuring 2008 and 2011, for China CARES, the Median of general population HIV test rate were 1.8%, 2.5%, 3.2% and 5.5%, the Median of spouse of PLWHA HIV test rate were 80.9%, 85.7%, 91.8% and 100.0%, the Median of ART coverage were 60.0%, 66.7%, 76.1% and 92.0%, the Median of PLWHA CD4 test rate during the past 6 months were 27.7%, 45.4%, 58.6% and 75.3%, the Median of FSW intervention coverage were 43.8%, 67.8%, 73.3% and 90.9%, the Median of IDU intervention coverage were 18.2%, 24.0%, 34.0% and 72.4%. The indicators of China CARES increased steadily from 2008 to 2011 in HIV testing expansion, treatment expansion and behavior intervention expansion; Compared to 2008, the percentage of the China CARES which had great progress of the 6 indicators were 98.4% (304/309), 98.3% (286/291), 94.0% (281/299), 93.5% (288/308), 91.8% (279/304) and 90.0% (223/247). in 2008, 3 indicators which were ART coverage, PLWHA CD4 test rate during the past 6 months and FSW intervention coverage were lower than national average (6.9%, 17.9% and 30.9%), the general population HIV test rate, spouse of PLWHA HIV test rate and IDU intervention coverage were higher than national average (3.4%, 64.3% and 22.8%), with the China CARES project going on, in 2011, key indicators which were general population HIV test rate, spouse of PLWHA HIV test rate, ART coverage, PLWHA CD4 test rate during the past 6 months, FSW intervention coverage and IDU intervention coverage were all higher than national average (6.5%, 80.6%, 81.9% and 55.9%).the proportions of China CARES sites whose 6 indicators were higher than national average in 2008 were 32.7% (101/309), 60.6% (149/246), 37.4% (99/265), 61.1% (181/296), 64.0% (174/270) and 45.3% (73/161), and the proportions increase annually to 2011 were 44.0% (136/309), 89.3% (260/291), 76.6% (229/299), 77.9% (240/308), 91.4% (278/304) and 64.8% (160/247).

CONCLUSIONAn obvious achievements have been made in the areas of HIV/AIDS prevention and control among China CARES sites during 2008 and 2011 than the national average.

As the severity of the HIV epidemic in China grew, National Free Antiretroviral Treatment (ART) Program was announced since 2003. Even though there still were many difficulties, China had obtained great achievements in fighting against HIV. Over 52 000 adult patients had received first-line HAART thus far and the mortality of AIDS in China decreased significantly. This paper presents an overview of the HIV/AIDS epidemic in China; the status of national free ART program, the difficulties suffered and the achievements made since the initiation of program and the challenges ahead for continued progress for China. This paper also provides suggestions to overcome these challenges.
