ABSTRACT
<p><b>OBJECTIVE</b>To study the prevalence of antibody to hepatitis C virus (anti-HCV) among newly reported HIV infection cases in Henan province, 2012-2014.</p><p><b>METHODS</b>HIV-1 BED incidence test and anti-HCV test were conducted in newly diagnosed HIV infection cases in Henan, which were reported through national AIDS information system between 1 July 2012 and 30 June 2014.</p><p><b>RESULTS</b>The data of 4 267 newly reported HIV-1 infection cases were analyzed, the positive rate of anti-HCV was 13.19% (563/4 267). The anti HCV was highest in those infected with HIV through injection drug use (77.27%), the anti-HCV positive rates in those infected with HIV through blood donation/transfusion, heterosexual contact, homosexual contact and mother-to-child transmission were 15.06%, 15.81%, 3.74% and 8.96%, respectively. Kaifeng (32.04%), Nanyang (14.67%), Shangqiu (25.00%), Zhumadian (25.00%) and Zhoukou (18.86%) were the first five prefectures with the high anti-HCV positive rates. The anti-HCV positive rate in BED positive patients (recent HIV-1 infections) was 7.50% (86/1 146). The multivariate logistic regressions analysis revealed that BED negative, aged >40 years, being farmer, HIV infection though injection drug use and living in in Kaifeng, Nanyang, Shangqiu, Zhumadian and Zhoukou were the risk factors for HCV infection.</p><p><b>CONCLUSION</b>The positive rate of anti-HCV declined between 2012-2014 in newly reported HIV infection cases in Henan, but the positive rate of anti-HCV was high in risk population and in some areas.</p>

<p><b>OBJECTIVE</b>To evaluate the network reporting quality of hepatitis C cases in Henan province in 2014.</p><p><b>METHODS</b>The data of hepatitis C case reporting was collected from selected medical institutions in Henan province in 2014. According to current reporting standards, the evaluation of reporting rate, the timely reporting rate, the underreporting rate, the false reporting rate and the anti HCV positive and HCV-RNA positive reporting rate of hepatitis C cases were evaluated.</p><p><b>RESULTS</b>A total of 2 778 hospitalized hepatitis C cases in 170 medical and health institutions were surveyed, the reporting rate was 84.10%, the timely reporting rate was 100.00%, the underreporting rate was 15.90%, the false reporting rate was 13.17% and the anti-HCV positive and HCV-RNA positive reporting rate was 91.06%. The coincidence rate of diagnosis and reporting was 58.61%, the coincidence rate of acute or chronic cases was 30.93%. More clinical diagnosed cases were underreported. The coincidence rate of laboratory confirmed cases reporting were low. The diagnosis and reporting coincidence rate was low in provincial medical institutions.</p><p><b>CONCLUSION</b>In Henan, the hepatitis C case reporting rate was high, the anti-HCV positive and HCV-RNA positive reporting rate needs to be improved. The coincidence rate of hepatitis C reporting was low. Underreporting and false reporting still existed. The quality of hepatitis C reporting in provincial medical and health institutions needs to be improved.</p>

<p><b>OBJECTIVE</b>To study the condition of HIV-1 drug resistance mutation among failures of first-line antiretroviral therapy in Henan province.</p><p><b>METHOD</b>The sub platform of China's legal infectious disease monitoring information reporting system-HIV/AIDS integrated prevention and control data information management system was used to collect the information of patients experiencing first-line antiretroviral treatment failure (virus load ≥ 1 000 copies/ml) more than one year among nine cities of Henan in 2011. A total of 40 cases with no information and 212 cases with incomplete drug resistance results were deleted, and 1 922 cases were included in this study and genotype resistance testing was carried out. Non-conditional logistic regression analysis was used to analyse the influencing factors of drug resistance mutation.</p><p><b>RESULTS</b>A total of 1 922 cases were included in the analysis. 1 039 cases were males, 833 cases were females, the age was (45.7 ± 12.1) years, 82.73% (1 590) were married, and 87.93% (1 690) were transmitted by blood. 64.20% (1 234) patients acquired drug resistance. Nucleoside reverse transcriptase inhibitor (NRTI), non-nucleoside reverse transcriptase inhibitor (NNRTI) and protease inhibitor (PI) resistance mutations were found in 62.59% (1 203), 49.74% (956) and 0.94% (18) of subjects, respectively. 42.09% (809) of patients harbored NRTI and NNRTI resistance mutations synchronously. ≥ 1TAM was the most commonly emerged NRTI resistance mutation (41.94% (806)), the prevalences of TAM-1 and TAM-2 were 8.48% (163) and 4.24% (81), respectively. K65R/N and Q151M complex existed in 23 and 4 patients, respectively. K103N/S was the most commonly emerged NNRTI resistance mutation (34.32% (659)). Non-conditional logistic regression analysis showed that, factors associated with high drug resistance were the following: transmitted by mother to child (OR = 9.05, 95% CI: 1.14-72.12), clinical stage was IV (OR = 1.70, 95% CI: 1.09-2.66) and 5-year-treated (OR = 1.59, 95% CI: 1.03-2.47). Factors associated with low drug resistance were the following: 1-year-treated (OR = 0.19, 95% CI: 0.13-0.27).</p><p><b>CONCLUSION</b>Complex patterns of HIV-1 drug resistance mutations were identified among individuals experiencing failure of first-line antiretroviral therapy in Henan province. Factors associated with high drug resistance were lived in Luohe, Shangqiu, Nanyang, Xinyang, transmitted by mother to child, clinical stage was IV, and 5-year-treated.</p>

<p><b>OBJECTIVE</b>To understand the one-year effect of HCV/HIV co-infected patients who had received AIDS second-line antiretroviral treatment after failure virologically, on the first-line therapy.</p><p><b>METHODS</b>HCV and HIV antibody positive patients who had experienced virological failure but received at least one-year AIDS first-line treatment, were recruited from May to October 2012 in Xincai, Queshan and Weishi of Henan province. 6-months and 12-months follow-up programs were carried out after the regimen had been changed to AIDS second-line antiretroviral treatment, CD4⁺ T lymphocyte count, HIV-1 virus load and HIV-1 drug resistance were performed.</p><p><b>RESULTS</b>Eighty-one cases of eligible patients were selected and followed by an amelioration of CD4 median at 6-month and 12-month follow-up period. Data showed that the baseline, 6-months and 12-months CD4 medians were 266 cells/µl, 275 cells/µl and 299 cells/µl (χ² = 8.214, P = 0.009). The ratio of HIV virus load suppression patients at 6-months and 12-months follow-up increased to 46.84% and 50.00%, respectively. Frequencies of HIV drug resistance also decreased at the baseline, 6-months and 12-months, with ratios as 66.67%, 26.58% and 27.63% (χ² = 29.362, P = 0.000), respectively. Ratios of patients that holding NRTI and NNRTI drug resistance appeared coinstantaneous decrease at the baseline, 6-months and 12-months, as 51.85%, 18.99% and 17.11% (χ² = 14.230, P = 0.005). At the baseline, the ratios of patients resisted to 3TC, ABC and FTC were all more than 50%, with AZT, D4T and DDI between 41%-44% while TDF appeared as 33.33%, then all of them declined to 12%-18% at the 6-month and 12-month follow-up periods. 65.43% of the patients resisted to both NVP and EFV but declined to 24%-27% at 6 months and 12 months.</p><p><b>CONCLUSION</b>HCV/HIV co-infected patients experienced virological failure of AIDS first-line therapy were ameliorated after changing to use second-line antiretroviral treatment for 6-months, but did not show constant positive effect at the 12-month end point.</p>
