RESUMEN
OBJECTIVE: To evaluate the therapeutic effect of highly active anti-retroviral therapy (HAART) in treatment-naïve Chinese patients with AIDS, to provide evidences for standardizing HAART. METHODS: Seventy-four treatment-naive AIDS patients were initiated with HAART and followed up regularly for 3 years. The clinical and laboratory data, side effects and drug resistance were observed and analyzed during the follow-up period. RESULTS: Of the 74 patients, 46 were males and 28 were females, with the average age being 42 years. The mean HIV viral load was (2.2 ± 2.0) × 10(5) copies/ml and the baseline mean CD(4)(+)T lymphocyte count was (62 ± 71) cells/µl before treatment. After treatment for 3, 6, 12, 18, 24, 30 and 36 months, the percentage of undetectable HIV viral road (less than 50 copies/ml) was 71.6%, 83.8%, 75.7%, 77.0%, 82.4%, 81.1% and 79.7% respectively, and CD(4)(+)T lymphocyte count ascended to (167 ± 105), (177 ± 129), (238 ± 137), (290 ± 158), (304 ± 191), (331 ± 175) and (352 ± 202) cells/µl. The increase in amplitude of CD(4)(+)T lymphocyte count in different periods examined was different, with the period of 0-3 months post-treatment demonstrating the most obvious augmentation (P < 0.01). The most common adverse reactions were liver function injury (52/74, 70.3%), hyperlipemia (52/74, 70.3%), hematopoietic inhibition of the bone marrow (33/74, 44.6%), peripheral neuritis (32/74, 43.2%) and lipoatrophy (26/74, 35.1%). Clinical drug resistance were found in nine patients and HIV gene mutations were detected in these patients. CONCLUSIONS: Chinese treatment-naive AIDS patients have achieved good virological and immunological response to generic-drug-predominant HAART regimes with low drug resistance, but relatively more side effects.

Dual therapy with lopinavir/ritonavir (LPV/r) plus lamivudine (3TC) has been demonstrated to be non-inferior to the triple drug regimen including LPV/r plus two nucleoside reverse transcriptase inhibitors (NRTIs) in 48-week studies. However, little is known about the long-term efficacy and drug resistance of this simplified strategy. A randomized, controlled, open-label, non-inferiority trial (ALTERLL) was conducted to assess the efficacy, drug resistance, and safety of dual therapy with LPV/r plus 3TC (DT group), compared with the first-line triple-therapy regimen containing tenofovir (TDF), 3TC plus efavirenz (EFV) (TT group) in antiretroviral therapy (ART)-naïve HIV-1-infected adults in Guangdong, China. The primary endpoint was the proportion of patients with plasma HIV-1 RNA < 50 copies/ml at week 144. Between March 1 and December 31, 2015, a total of 196 patients (from 274 patients screened) were included and randomly assigned to either the DT group (n = 99) or the TT group (n = 97). In the primary intention-to-treat (ITT) analysis at week 144, 95 patients (96%) in the DT group and 93 patients (95.9%) in the TT group achieved virological inhibition with plasma HIV-1 RNA <50 copies/ml (difference: 0.1%; 95% CI, -4.6-4.7%), meeting the criteria for non-inferiority. The DT group did not show significant differences in the mean increase in CD4+ cell count (247.0 vs. 204.5 cells/mm3; p = 0.074) or the CD4/CD8 ratio (0.47 vs. 0.49; p = 0.947) from baseline, or the inflammatory biomarker levels through week 144 compared with the TT group. For the subgroup analysis, baseline high viremia (HIV-1 RNA > 100,000 copies/ml) and genotype BC did not affect the primary endpoint or the mean increase in CD4+ cell count or CD4/CD8 ratio from baseline at week 144. However, in patients with genotype AE, the DT group showed a higher mean increase in CD4+ cell count from baseline through 144 weeks than the TT group (308.7 vs. 209.4 cells/mm3; p = 0.038). No secondary HIV resistance was observed in either group. Moreover, no severe adverse event (SAE) or death was observed in any group. Nonetheless, more patients in the TT group (6.1%) discontinued the assigned regimen than those in the DT group (1%) due to adverse events. Dual therapy with LPV/r plus 3TC manifests long-term non-inferior therapeutic efficacy, low drug resistance, good safety, and tolerability compared with the first-line triple-therapy regimen in Guangdong, China, indicating dual therapy is a viable alternative in resource-limited areas.

RESUMEN
BACKGROUND: The prevalence of hepatitis B virus (HBV) infection is high among individuals infected with human immunodeficiency virus (HIV) in China. Both HIV and HBV can be treated with tenofovir disoproxil fumarate (TDF) and lamivudine (3TC), so we evaluated the safety and efficacy of combination antiretroviral therapy (ART) that included TDF, 3TC, and efavirenz (EFV) among ART-naive individuals who were co-infected with HIV and HBV. METHODS: One hundred HIV/HBV co-infected ARV-naive individuals were started on the regimen of TDF, 3TC, and EFV, and the levels of plasma HBV DNA, HIV RNA, and biochemical evaluation related to the function of liver and kidney were analyzed. RESULTS: Concerning efficacy, this study found that by week 48, the vast majority co-infected participants receiving this ART regimen had undetectable HBV DNA levels (71%) and/or HIV RNA levels (90%). Concerning safety, this study found that the median estimated glomerular filtration rate of participants decreased from baseline (109 ml·min-1·1.73 m-2) to week 12 (104 ml·min-1·1.73 m-2) but was almost back to baseline at week 48 (111 ml·min-1·1.73 m-2). CONCLUSION: This combination ART regimen is safe and effective for patients with HIV/HBV co-infection.

AIM: To investigate the clinical significance of expression of tissue factor (TF) and tissue factor pathway inhibitor (TFPI) in ulcerative colitis (UC). METHODS: Thirty UC specimens taken by colonoscopy from patients with active UC treated at the Department of Pathology, Central Hospital Affiliated to Shenyang Medical College from February 2010 to January 2012 were included in an experimental group, and 30 normal colon tissue samples taken by colonoscopy from non-UC patients were included in a control group. Expression of TF and TFPI in UC and normal colon tissue samples was detected by immunohistochemistry. RESULTS: The positive rate of TF in UC was significantly higher than that in normal colon tissue (63% vs 33%, χ(2) = 5.41, P < 0.05). The positive rate of TFPI in UC was also significantly higher than that in normal colon tissue (43% vs 17%, χ(2) = 5.08, P < 0.05). CONCLUSION: Positive rates of TF and TFPI expression in UC are significantly higher than those in normal colon tissue. TF and TFPI may play an important role in the pathogenesis of UC.

OBJECTIVE: In this study, researchers investigated the demographic and clinical characteristics of AIDS patients who died in hospitals, analyzed the specific causes of death, and looked for the correlation between specific cause of death and their clinical characteristics. METHODS: Data of clinical characteristics of patients and their specific causes AIDS of death who died in the seven hospitals from 2009 to 2010 were collected retrospectively. All the specific causes of death were classified according to the Cause of Death (CoDe) project protocol. Univariate analysis and multivariate logistic regression analysis were used to find the association between some categorical variables and the risk for AIDS patients died from AIDS related illnesses. RESULTS: Clinical characteristics and the cause of death of the 381 deceased in seven hospitals in this study were collected. 82.4% were male, with priority as 30-45 years old. 123 (32.3%) death patients had received ART before death. In all death cases, the cause of death of 252 patients (66.1%) were due to AIDS related diseases, with opportunistic infections the most (92.4%). Tubercle bacillus, infection of Penicillium marneffei and Pneumocystis jiroveci were the three leading causes of opportunistic infection deaths. Of 129 patients who died of non-AIDS related disease, non-AIDS infection (29.5%), hepatitis (22.5%), and non-AIDS malignancy(10.1%)were the first three causes of death. The cause of death in patients who had injecting drug use behavior within one year, had not received ART or not long enough, with opportunistic infections, without hepatitis, with the last low CD4 cell counts before death etc. were tend to due to AIDS related disease. CONCLUSION: Opportunistic infections, non-AIDS related infections and hepatitis were the three leading causes of death in this study. The duration of time on ART had impact on the patient's cause of death. The HIV infected patients who had received ART before death had more risk to die of non-AIDS related disease, compared to patients who had not. The longer time they had accessed to ART, the less likely they would die on non-AIDS related illnesses.
