OBJECTIVE: To investigate the efficacy of chemotherapy combined with antivirals in adult T-cell leukemia/lymphoma (ATLL) patients and the prognostic factors. METHODS: Forty nine patients with previously treated or treatment-nave ATLL from January 2018 to January 2021 were included in our study. The patients were divied into two groups according to whether they received antiviral treatment, twenty-seven patients were treated with chemotherapy combined with antivirals, including thirteen patients treated with recombinant interferon alpha-2b and CHOP therapy, eight patients treated with zidovudine combined with CHOP therapy, and 6 patients treated with CHOP regimen combined with interferon and zidovudine. Twenty-two patients were treated with CHOP therapy. The changes of symptom, hematological parameters, lactic dehydrogenase, β2-microglobulin, and the Ki-67 positive rate were compared between the two groups before and after treatments. The clinical efficacy of chemotherapy combined with antiviral therapy for ATLL was evaluated. The antiviral effect was assessed by detecting HTLV-1 virus copy number, and prognostic factors were analyzed. RESULTS: The median follow-up time was 14 months. Compared with the patients treated with chemotherapy alone, the patients treated with chemotherapy combined with antivirals had lower tumor and virus loads, lower white blood cell count, lower lactate dehydrogenase level, lower β2-microglobulin lever, and lower Ki-67 positive rate (all P<0.05). The total effective rate of patients treated with chemotherapy combined with antivirals was significantly higher than those of patients treated with chemotherapy alone (63.0% vs 31.8%, P=0.035). The one-year overall survival (OS) rates of chemotherapy combined with antivirals groups and chemotherapy alone group were (74.1±2.9)％ and (40.9±2.1)％ (P=0.021), respectively. The one-year progress free survival (PFS) rates were (51.9±3.3)％ and (13.6±2.8)％ (P=0.017), respectively. Multivariable Cox regression analysis showed that HTLV-1 virus load (HR=7.518, 95%CI: 2.517-36.192, P=0.013) and antiviral therapy ［HR=5.617 (95%CI 1.803-11.293), P=0.027］ were independent prognostic factors for the long-term efficacy. CONCLUSION Addition of antivirals to chemotherapy can prolong PFS and OS in ATLL patients. HTLV-1 virus load and antiviral therapy are independent prognostic factors for ATLL patients.

OBJECTIVETo investigate the survival rate of AIDS patients after receiving antiretroviral therapy(ART) in Henan province and to determine factors associated with survival status.

METHODSDatabase of AIDS patients receiving ART were downloaded from China Information System for Disease Preventioin and Control-AIDS, retrospective study method was conducted to analyze the information.

INCLUSION CRITERIAinitially received national free ART during January, 2005 to December, 2014; aged 15 years or above; and with relatively complete baseline information and follow-up information. The accumulated survival rate of AIDS patients was calculated by life table method and the influencing factors were analyzed by Cox proportional hazard model.

RESULTSTotal 30 376 AIDS patients were enrolled in this study. During the follow-up period, a total of 3 927 cases died from HIV/AIDS related diseases. The mortality of all patients was 3.2/100 person year. After 1, 5, 10 years after the initiation of ART, the rates of accumulate survival rate were 93.7%, 85.3%, and 78.4%, respectively. Stepwise regression was used to conduct the time multiple factors analysis, the results showed that man (HR=1.28, 95%CI: 1.20-1.37), older age (HR=1.20, 95% CI: 1.16-1.24), others marital status except marrage or cohabitation (HR=1.20,95% CI: 1.12-1.29), more number of symptoms (HR=1.11, 95%CI: 1.07-1.14), initial treatment were main stavudine (D4T) or zidovudine (AZT)+ didanosine(DDI)+ nevirapine (NVP) or efevirenz (EFV) (HR=1.12, 95% CI: 1.04-1.20), missing drug in the past 7 days (HR=18.36,95%CI: 17.08-19.74) among AIDS patients had high mortality risk, homosexuality sexual transmission (HR=0.59, 95% CI: 0.40-0.87), higher baseline count of CD4(+)T lymphocyte (relative to 0-200 cells/µl group, HR (95%CI) were 0.57 (0.53-0.62), 0.43(0.37-0.49), 0.33 (0.27-0.40) in 201-350 cells/µl group, 351-500 cells/µl group, and ≥501 cells/µl group, respectively), higher educations (HR=0.89, 95% CI: 0.83-0.95) had low mortality risk.

CONCLUSIONSurvival rate was higher after initial antiretroviral treatment among AIDS patients in Henan province. AIDS patient will have shorter survival time after antiviral treatment under one or more following conditions: higher age, male, initial treatment with D4T or AZT + DDI + NVP or EFV, lower baseline CD4 (+) T lymphocyte count, ever missed antiviral drugs in past 7 days of latest follow-up.

BACKGROUNDIn the era of highly active antiretroviral therapy (HAART), the use of antiretrovirals as post-exposure prophylaxis (PEP) was the most important strategy for preventing occupational exposure to blood or fluids containing human immunodeficiency virus (HIV). The objective of this study was to retrospectively evaluate the tolerability, safety, and side effects of a HAART regimen containing three antiretroviral drugs, consisting of zidovudine, lamivudine, and lopinavir/ritonavir, in healthcare personnel (HCP) who experienced occupational exposure to HIV.

METHODSThe tolerability, safety, and side effects in 26 HCPs who experienced PEP and in 27 HIV/AIDS patients with HAART regimen, AZT+3TC+Lpv/r, were evaluated between January 2010 and December 2012.

RESULTSThe most frequent clinical side effect was fatigue (in 23 cases, 88.5%), and gastroenterological symptoms were the second most common side effects in HCP with PEP. Liver dysfunction was found in 10 cases (38.5%), while drug rash was found in 18 cases (69.2%) after PEP. The prevalence of side effects in HCPs who experienced PEP was higher than that in HIV/AIDS patients P < 0.05. One nurse (3.8%) experienced severe gastrointestinal symptoms, which led to withdrawal of PEP. No HIV infection was found during 6-month follow-up period.

CONCLUSIONHCPs who received occupational PEP with triple-drug regimen, AZT+3TC+Lpv/r, experienced different side effects, and the tolerability and safety of PEP regimen were good in this cohort.

BACKGROUNDAn zidovudine (AZT)-substitution regimen containing 24-week stavudine (d4T) followed by long-term AZT for HIV therapy is potential to trade off short-term AZT-related anemia and long-term risks associated with d4T in resource-limited settings. However, evidence is scarce. This study aims to assess the efficacy and safety of AZT-substitution regimen, aiming to find a regimen with better efficacy, less adverse events, and more affordability in resource-limited settings.

METHODSThis prospective, multicenter study enrolled 499 (190 on d4T regimen, 172 on AZT regimen, and 137 on AZT-substitution regimen) HIV-1-infected subjects who initiated combined antiretroviral therapy and attended follow-up visits over 96 weeks from 2009 to 2011. Lamivudine (3TC) and either nevirapine (NVP) or efavirenz (EFV) were the other two drugs in the antiretroviral regimens. Virologic and immunologic responses and adverse events were monitored at baseline and at weeks 4, 12, 24, 36, 48, 60, 72, 84, and 96.

RESULTSIn terms of hematological adverse effects, AZT-substitution group had similar safety profiles to d4T group and was superior to AZT group. In comparison with AZT-substitution group, AZT group was associated with higher risk of developing anemia (adjusted hazard ratio (aHR) for anemia ≥ grade II, 8.44, 95% CI 1.81-39.46) and neutropenia (aHR for neutropenia ≥ grade II, 1.86, 95% CI 1.19-2.93). The prevalence of lipodystrophy in d4T group was 19.5%, while that in AZT-substitution group was zero. As to antiretroviral efficacy, these three groups showed no differences.

CONCLUSIONAZT-substitution regimen provides a relatively safe and effective first-line antiretroviral strategy in resource-limited settings.

Low bone mineral density (BMD) is common in HIV-infected patients. We aimed to describe the prevalence of low BMD and risk factors in Korean HIV-infected patients and to assess the effects of antiretroviral therapy (ART) on BMD. We retrospectively evaluated 224 HIV infected-patients. The prevalence of osteopenia and osteoporosis were 41.5% and 12.9%. These were much higher in 53 patients aged 50 yr and older (52.8% and 34.0%). Older age, lower body mass index, and ART > 3 months were independent risk factors for low BMD. Osteoporosis was more prevalent in patients on the abacavir-based regimen for < 1 yr than > or = 1 yr; however, it was more prevalent in patients on the zidovudine-based regimen for > or = 1 yr than < 1 yr (P = 0.017). Osteoporosis in patients on the abacavir-based regimen was more common in the spine than in the femur (P = 0.01). Given such a high prevalence of low BMD, close monitoring of BMD for HIV-infected patients on ART is required. The different prevalence of osteoporosis over time and affected areas between two regimens suggest they may play roles in different mechanisms in bone loss.

BACKGROUNDThe pharmacokinetics of zidovudine (AZT) are possibly influenced by weight, age, sex, liver and renal functions, severity of disease, and ethnicity. Currently, little information is available on the steady-state pharmacokinetics of AZT in Chinese HIV-infected patients. The current study aimed to characterize the steady-state pharmacokinetics of AZT in a Chinese set-up.

METHODSEleven Chinese HIV-infected patients were involved in the steady-state pharmacokinetic study. In total, 300 mg of AZT, as a part of combination therapy, was given to patients, and serial blood samples were collected for 12 hours. The samples were measured by a high-performance liquid chromatography (HPLC) assay, and the results were analyzed by both the non-compartment model and the one-compartment model.

RESULTSThe C(max) of AZT in Chinese patients was higher than that in non-Asian patients. The half-life of AZT, analyzed by the non-compartment model (P = 0.02), in male patients ((1.02 ± 0.22) hours) was shorter than that of AZT in female patients ((1.55 ± 0.29) hours). The AZT clearance, analyzed by the one-compartment model (P = 0.045), in male patients ((262.60 ± 28.13) L/h) was higher than that in female patients ((195.85 ± 60.51) L/h).

CONCLUSIONThe present study provides valuable information for the clinical practice of AZT-based highly active antiretroviral therapy in a Chinese set-up.

In the two decades since AZT was first approved for clinical use in 1987, 24 additional antiretroviral agents have been approved. They include 7 nucleoside analogs, a nucleotide analog and 4 non-nucleoside reverse transcriptase inhibitors, 10 protease inhibitors, 2 entry inhibitors and an integrase inhibitor. More than 20 investigational agents are currently being studied in clinical trials. Highly active antiretroviral therapy (HAART), which involves a combination of anti-HIV-1 drugs, is extremely effective in suppressing HIV-1 replication and increasing CD4+ number and results in substantial reductions in HIV-1-related morbidity and mortality. In last 20 years, much has been learned about resistance to antiretroviral drugs, drug interactions and metabolic complications of antiviral drug use. Drugs are now selected on the basis of resistance tests and on the risk of specific drug complications in individual patients. As a result, decisions about the therapy of HIV/AIDS have become personalized and are made on a patient-by-patient basis. With appropriate medical management, a person with HIV-1 now has the possibility of a nearly normal life expectancy.

OBJECTIVETo explore the impacts of traditional Chinese medicine (TCM) on CD4 + T cell counts and human immunodeficiency virus (HIV) viral loads during the course of structured treatment interruption (STI) in highly active antiretroviral therapy (HAART).

METHODSNineteen HIV/ADIS patients were treated for 14 months as follows: initiated with zidovudine/lamivudine + efavirdine for 6 months, then discontinued the therapy and treated with TCM instead for 2 months. HAART was then reinitiated for another 3 months, and then discontinued and replaced with TCM for another 3 months. The changes of CD4 + T cell counts and HIV viral loads were measured.

RESULTSDuring the first STI of HAART, 43.8% of patients had no viral rebounds one month later, and 62.6% had stable or increased immune functions; 18.8% had no viral rebounds two months later, and 43.8% had stable or increased immune functions. Changes of viral loads were not significantly different between these two months (P = 0.097), while CD4 + T cell counts significantly decreased two months later compared with one month later (P = 0.043). During the second STI of HAART, 33.3% of patients had no viral rebounds one month later, and 64.3% had stable or increased immune functions; 13.3% had no viral rebounds 3 months later and 46.6% had stable or increased immune functions. Changes of viral loads had significant difference (P = 0. 017), while CD4 + T cell counts at month 12 elevated significantly compared with the baseline (P = 0.014).

CONCLUSIONSTCM can suppress the viral rebounds during STI-HAART, maintain immune functions. However, this effect may decrease along with the prolongation of STI-HAART.
