Integrase strand transfer inhibitors (INSTIs) are the cornerstone of modern antiretroviral therapy (ART), achieving durable plasma HIV-1 suppression in most people living with HIV (PLWH). Previous comparisons of INSTI- and non-INSTI-based regimens have largely focused on HIV reservoir proviral assessments— typically total HIV DNA —without assessing reservoir activity. In this first functional comparison, we measured cell-associated (CA) short HIV-1 RNA transcripts, a marker of active transcription, alongside HIV-1 DNA in white blood cells from 92 virally suppressed individuals on INSTI-based (n = 73) or non-INSTI-based (n = 19) ART. CA short RNA transcripts were detected in all participants and HIV-1 DNA in 99 %, despite undetectable plasma viremia in >93 %. Individuals with prior “blips” — defined as a maximum of two episodes with 20–200 copies/mL plasma HIV-1 RNA over more than two years — had significantly higher CA RNA and HIV DNA than non-blip participants, confirming our previous findings. However, reservoir size and transcriptional activity did not differ significantly between INSTI and non-INSTI groups. These findings indicate that while INSTIs effectively block new integration events, they do not suppress ongoing transcription from the latent reservoir. Therapeutic strategies directly targeting HIV transcription should therefore be prioritized in cure-oriented research for PLWH on long-term suppressive ART.
整合酶链转移抑制剂(intis)是现代抗逆转录病毒治疗(ART)的基石,在大多数HIV感染者(PLWH)中实现持久的血浆HIV-1抑制。以前对基于INSTI和非基于INSTI的方案的比较主要集中在HIV病毒库的预先评估上——通常是HIV病毒的总DNA——而没有评估病毒库的活性。在第一个功能比较中,我们测量了细胞相关(CA)短的HIV-1 RNA转录物(一种活性转录标记物)和HIV-1 DNA,这些转录物来自92个病毒抑制个体的白细胞,这些个体接受基于inist (n = 73)或非基于inist (n = 19)的抗逆转录病毒治疗。在所有参与者中检测到CA短RNA转录物,99%的参与者检测到HIV-1 DNA,尽管93%的参与者检测不到血浆病毒血症。先前有“突变”的个体(定义为两年以上最多两次出现20-200拷贝/mL血浆HIV-1 RNA)的CA RNA和HIV DNA明显高于无突变的参与者,证实了我们之前的发现。然而,储层大小和转录活性在INSTI组和非INSTI组之间没有显著差异。这些发现表明,尽管iniss有效地阻断了新的整合事件,但它们并不抑制潜伏库正在进行的转录。因此,在以治疗为导向的长期抑制性抗逆转录病毒治疗的PLWH研究中,应优先考虑直接针对HIV转录的治疗策略。

Background

Integrase strand transfer inhibitors (INSTIs) are widely used in HIV treatment, yet few large-scale studies have examined acquired resistance (AR) at the population level. This study assessed the prevalence, patterns, and clinical implications of AR to INSTIs in Chile over a 12-year period.

Methods

We analyzed 5266 genotypic sequences from ART-experienced individuals with confirmed virological failure and INSTI-based regimens between 2012 and 2023. Resistance-associated mutations were classified using the Stanford HIVdb algorithm. Resistance trends were compared between pre-pandemic (2012–2019) and post-pandemic (2020–2023) periods.

Results

High AR rates were observed for first-generation INSTIs: raltegravir (28 %) and elvitegravir (27.7 %). Lower resistance levels were found for dolutegravir (8.3 %), bictegravir (8.3 %), and cabotegravir (18.7 %). Major resistance mutations included N155H (25.2 %), Q148 H/K/R (17.2 %), and Y143R (14.3 %). Notably, Q148 H/K/R mutations were always found in combination with other major mutations. Subtype-specific differences were observed, with higher first-generation INSTI resistance in subtype F (55.6 %) than in subtype B (23.9 %). Post-pandemic resistance increased significantly for first-generation INSTIs (25 % vs. 31 %, p < 0.05). The mutation N155H, while not impacting DTG or BIC significantly, conferred intermediate resistance to CAB. CAB resistance was detected despite its absence in treatment protocols, likely due to cross-resistance pathways.

Conclusions

Acquired INSTIs resistance in Chile is high, especially for first-generation drugs. These findings highlight the need for nationwide molecular surveillance and pre-treatment genotyping, particularly before initiating long-acting regimens such as CAB-LA. Strategic monitoring will be critical to maintaining the efficacy of current and next-generation INSTIs.
整合酶链转移抑制剂(iniss)广泛用于HIV治疗,但很少有大规模的研究在人群水平上检测获得性耐药(AR)。本研究评估了智利12年来急性呼吸道感染患者的患病率、模式和临床意义。方法分析2012年至2023年间确诊病毒学失败的抗逆转录病毒治疗个体和基于inst的治疗方案的5266个基因型序列。使用Stanford HIVdb算法对抗性相关突变进行分类。比较了大流行前(2012-2019年)和大流行后(2020-2023年)期间的耐药性趋势。结果第一代inis的AR发生率较高:雷替重力韦(28%)和韦替重力韦(27.7%)。多替格拉韦(8.3%)、比替格拉韦(8.3%)和卡替格拉韦(18.7%)的耐药水平较低。主要耐药突变为N155H(25.2%)、Q148 H/K/R(17.2%)和Y143R(14.3%)。值得注意的是,Q148 H/K/R突变总是与其他主要突变组合发现。观察到亚型特异性差异,F亚型(55.6%)的第一代耐药率高于B亚型(23.9%)。第一代insis大流行后耐药性显著增加(25%对31%,p < 0.05)。突变N155H虽然对DTG或BIC没有显著影响,但对CAB具有中等抗性。尽管在治疗方案中没有检测到CAB耐药性,但可能是由于交叉耐药途径。结论智利获得性药物耐药较高,尤其是第一代药物。这些发现强调了在全国范围内进行分子监测和治疗前基因分型的必要性,特别是在开始长效方案(如CAB-LA)之前。战略监测对于维持当前和下一代信息系统的效力至关重要。

Background

Multiple analyses have suggested that osteopontin (OPN) is involved in acute and chronic liver disease. We aimed to investigate the value of serum OPN in predicting the short-term prognosis of patients with hepatitis B-related acute-on-chronic liver failure (HBV-ACLF).

Methods

A total of 205 patients with HBV-ACLF were enrolled in a retrospective study and stratified into survivors and non-survivors according to their 90-day prognosis. Multivariate Cox regression and receiver operating characteristic curves were used to evaluate the predictive value of serum OPN levels for the 90-day prognosis of patients with HBV-ACLF.The prevalence of different OPN levels (<36.8 ng/ml; ≥36.8 ng/ml) and their relationship with 90-day prognosis were investigated.

Results

Patients with HBV-ACLF had significantly higher serum OPN levels than patients with HBV-LC, patients with CHB, and healthy subjects. Patients were assigned to low- and high-level OPN groups according to the cut-off value of OPN (36.8 ng/ml). Survival curves revealed that patients with high OPN levels had significantly poorer survival than those with low OPN levels, as determined using Kaplan-Meier analysis. Importantly, Multivariate Cox regression analysis revealed that OPN levels were an independent risk factor for 90-day adverse outcomes in patients with HBV-ACLF according to the fully adjusted Model IV.

Conclusions

Our results demonstrated that plasma OPN level is a clinically meaningful biomarker for predicting the short-term prognosis of patients with HBV-ACLF.
多项分析表明,骨桥蛋白(OPN)参与急性和慢性肝脏疾病。我们的目的是研究血清OPN在预测乙型肝炎相关急性-慢性肝衰竭(HBV-ACLF)患者短期预后中的价值。方法对205例HBV-ACLF患者进行回顾性研究,并根据患者90天预后将其分为幸存者和非幸存者。采用多因素Cox回归和受试者工作特征曲线评价血清OPN水平对HBV-ACLF患者90天预后的预测价值。观察不同OPN水平(<36.8 ng/ml;≥36.8 ng/ml)的患病率及其与90天预后的关系。结果HBV-ACLF患者血清OPN水平明显高于HBV-LC患者、CHB患者和健康人。根据OPN的临界值(36.8 ng/ml)将患者分为低、高水平OPN组。根据Kaplan-Meier分析,生存曲线显示,高OPN水平的患者比低OPN水平的患者生存期明显较差。重要的是,多因素Cox回归分析显示,根据完全调整的模型iv,血浆OPN水平是HBV-ACLF患者90天不良结局的独立危险因素。结论血浆OPN水平是预测HBV-ACLF患者短期预后的有临床意义的生物标志物。

Evaluation of CD4 T cell status in early HIV infection is critical for developing strategies targeting HIV replication. In this study, we infected CD4 T cells with HIV-1 and investigated the cell survival mechanisms in HIV-infected versus uninfected cells during early HIV infection. Notably, HIV-infected CD4 T cells exhibited elevated levels of phosphorylated eukaryotic translation initiation factor 2-alpha (p-eIF2α) compared to uninfected cells. Importantly, inhibition of protein kinase R (PKR) in HIV-infected cells significantly suppressed HIV p24 protein expression by disrupting HIV reverse transcription and integration. These results suggest that targeting PKR could be a promising therapeutic approach against HIV infection.
评估CD4 T细胞在早期HIV感染中的状态对于制定针对HIV复制的策略至关重要。在这项研究中,我们用HIV-1感染CD4 T细胞,并研究了HIV感染和未感染细胞在HIV感染早期的细胞存活机制。值得注意的是,与未感染的细胞相比,hiv感染的CD4 T细胞表现出磷酸化的真核翻译起始因子2- α (p-eIF2α)水平升高。重要的是,抑制HIV感染细胞中的蛋白激酶R (PKR)通过破坏HIV逆转录和整合显著抑制HIV p24蛋白的表达。这些结果表明,靶向PKR可能是一种有希望的治疗HIV感染的方法。

Objective

Analytical treatment interruption (ATI) is crucial for assessing the efficacy of HIV-1 cure strategies. Recent cure studies have implemented more flexible ART restart criteria, permitting higher plasma viral loads (pVLs) for longer periods, which could potentially impair CD4+ T cell recovery even following ART resumption.

Design

We conducted a pooled analysis of six clinical HIV cure trials that included an ATI to evaluate the impact of magnitude and duration of plasma viremia during ATI on CD4+ T cell dynamics.

Methods

Wilcoxon signed-rank or rank-sum test was used to analyze differences in CD4+ T cell counts from 3 time points: 1) pre-ATI, 2) ART resumption, and 3) ART-induced viral re-suppression, with analyses stratified by peak pVL (≤10,000 or >10,000 copies/mL) or by duration of viremia (0–14, 15–28, or >28 days).

Results

Among 114 participants, we found no change in CD4+ T cell counts from pre-ATI to post-ATI (at viral re-suppression, P = 0.80). We also found no impact of low (≤10,000 copies/mL) versus high (>10,000 copies/mL) peak viremia on CD4+ T cell counts at the time of ART resumption or viral re-suppression (P = 0.48, P = 0.88, respectively). Similarly, the change in CD4+ T cell count from pre-ATI to viral re-suppression did not differ significantly between individuals with viremia lasting 0–14 days versus those with >28 days.

Conclusion

In our pooled analysis, high peak rebound pVLs and longer duration of viremia did not impair CD4+ T cell recovery following the resumption of ART, supporting the safety of more flexible ATIs in HIV-1 cure trials.
目的分析治疗中断(ATI)对评估HIV-1治愈策略的疗效至关重要。最近的治疗研究实施了更灵活的抗逆转录病毒治疗重启标准,允许更长时间内较高的血浆病毒载量(pvl),即使在抗逆转录病毒治疗恢复后,这也可能损害CD4+ T细胞的恢复。我们对包括ATI在内的六项临床HIV治愈试验进行了汇总分析,以评估ATI期间血浆病毒血症的程度和持续时间对CD4+ T细胞动力学的影响。方法采用swilcoxon符号秩和或秩和检验分析3个时间点(1)ati前、2)ART恢复和3)ART诱导病毒再抑制)CD4+ T细胞计数的差异,并按峰值pVL(≤10,000或10,000拷贝/mL)或病毒血症持续时间(0-14、15-28或28天)进行分层分析。在114名参与者中,我们发现从ati前到ati后CD4+ T细胞计数没有变化(在病毒再抑制时,P = 0.80)。我们还发现低(≤10,000拷贝/mL)和高(>10,000拷贝/mL)峰值病毒血症在ART恢复或病毒再抑制时对CD4+ T细胞计数没有影响(P = 0.48, P = 0.88)。同样,从ati前到病毒再抑制的CD4+ T细胞计数的变化在持续0-14天的病毒血症个体与持续28天的病毒血症个体之间没有显著差异。在我们的综合分析中,高峰值反弹pvl和更长的病毒血症持续时间不会损害抗逆转录病毒疗法恢复后CD4+ T细胞的恢复,支持更灵活的ATIs在HIV-1治愈试验中的安全性。

尽管全球努力消除作为公共卫生威胁的艾滋病毒,但撒哈拉以南非洲(SSA)仍然是该流行病负担最重的地区,约有70%的艾滋病毒感染者居住在这里,在艾滋病毒治疗研究领域的贡献有限,特别是在西非和中非(WCA)。这一差距主要是由于该地区的研究人员在当地发起和推进艾滋病毒治疗研究方面面临挑战,而法语国家的承诺较少。此外,由于对现有机会的认识有限和语言障碍,早期职业科学家在艾滋病毒治愈研究方面的能力建设仍然受到限制。尽管艾滋病毒非B亚型占全球循环亚型的89%,但治疗研究一直广泛关注B亚型(在美国和欧洲流行)。有趣的是,WCA(被称为具有广泛遗传多样性的艾滋病毒大流行中心)为治疗研究提供了独特的景观,有可能在各种艾滋病毒亚型中推广。这一观点讨论了为WCA建立艾滋病治疗学院的重要性,以支持来自法语国家的科学家、政策制定者和社区利益相关者为全球艾滋病治疗做出贡献。在讨论的基础上,建立“艾滋病毒治愈学院”成为以下方面的标志:(i)提高认识,(ii)建设能力,(iii)解决科学差距,(iv)发展网络,以及(v)促进将艾滋病毒治愈研究纳入国家艾滋病毒议程的宣传和政策简报。该学院被设想为一个中心,促进社区组织、艾滋病毒感染者、研究机构和决策者之间的关系。该中心还将支持该次区域的“倡导治愈”议程,加强多学科方法,以确定解决全球问题的当地艾滋病毒治愈研究重点。最重要的是,WCA的研究重点包括:(i)病毒库的测量和表征;(ii)免疫应答的研究,包括bNAbs、t细胞功能、细胞因子谱和宿主遗传因素;(iii)鉴定精英控制者和后处理控制者;(iv)开发无障碍技术,用于即时艾滋病毒DNA检测、生物标志物检测和潜伏期修饰剂,以支持功能性治愈战略;创新适合低资源环境的具有成本效益和可扩展的治疗干预措施;(vi)通过公民科学加强社区参与,解决伦理问题,并让艾滋病毒感染者参与治疗研究计划的共同设计;(七)建立区域培训平台,如以研究促治疗学院,以加强西非和中非的科学能力和合作。按照国际艾滋病协会(IAS)研究治疗学院的模式,世界艾滋病协会艾滋病毒治疗学院是实现艾滋病毒治疗目标的关键中心,通过地方行动有助于解决全球问题。

Background

Guidelines for Hepatitis B treatment released by the World Health Organization in 2024 include the potential for use of dual therapy, combining tenofovir with either emtricitabine or lamivudine. These fixed-dose combinations are also used for Pre-Exposure Prophylaxis (PrEP) in people at risk of Human Immunodeficiency Virus (HIV). We hypothesize that pre-existing HIV PrEP programmes can support access to HBV testing and treatment.

Methods

At the Africa Health Research Institute (AHRI) in KwaZulu Natal, South Africa, we evaluated PrEP uptake and retention amongst adolescents and young adults aged 15–30 years. We reviewed HBV status, acceptance of PrEP and retention in follow-up between June 2022–Sept 2024.

Results

15847 adolescents and young adults received an assessment in the community, of whom 3481/15847 (21.9 %) were eligible for sexual health prevention interventions. 3431/3481 (98.6 %) accepted HBV screening, of whom 21/3431 (0.6 %) tested positive for HBsAg. These 21 individuals had not previously been aware of their HBV status, but one was already on antiretroviral therapy for HIV infection. Amongst the others, 16/20 (80 %) were considered eligible for PrEP, and 15/16 started PrEP. When investigating retention in care, among 15 individuals due for a refill, 8/15 (53.3 %) returned at least once.

Conclusion

Sexual reproductive health and PrEP programmes provide an opportunity for HBV testing and treatment. However, attrition from the care cascade at each step highlights the pressing need for interventions that address barriers to sustainable delivery of long-term care.
世界卫生组织于2024年发布的乙型肝炎治疗指南包括使用双重治疗的可能性,将替诺福韦与恩曲他滨或拉米夫定联合使用。这些固定剂量组合也用于人类免疫缺陷病毒(HIV)风险人群的暴露前预防(PrEP)。我们假设预先存在的HIV PrEP规划可以支持获得HBV检测和治疗。方法在南非夸祖鲁-纳塔尔省的非洲卫生研究所(AHRI),我们评估了15-30岁的青少年和年轻人服用和保留PrEP的情况。我们回顾了2022年6月至2024年9月随访期间的HBV状态、PrEP接受情况和保留情况。结果15847名青少年和年轻人接受了社区评估,其中3481/15847人(21.9%)符合性健康预防干预的要求。3431/3481(98.6%)接受HBV筛查,其中21/3431 (0.6%)HBsAg阳性。这21个人之前并不知道自己的HBV状态,但其中一人已经在接受HIV感染的抗逆转录病毒治疗。在其他人中,16/20(80%)被认为符合PrEP的条件,15/16开始了PrEP。在调查护理保留情况时,在15名应补药的个人中,8/15(53.3%)至少返回一次。结论性生殖健康和预防规划为HBV检测和治疗提供了机会。然而,每一步护理级联的损耗突出表明,迫切需要采取干预措施,解决可持续提供长期护理的障碍。

Innate, cellular and humoral immunity in acute HIV infection (AHI) play crucial roles in dictating immunological and pathological outcomes. However, understanding immune cell dynamics in different compartments during AHI is limited. In this study, we characterized immune cells from matched blood and lymph node samples in the RV254 Thai AHI cohort, the RV304 Thai chronic HIV infection cohort, and HIV-negative individuals, using flow cytometry. Our results showed a significant loss of the CD4:CD8 ratio in both PBMCs and LNMCs during AHI. Similarly, we observed increased immune activation of CD4+ and CD8+ T cells in both blood and lymph node compartments during AHI. In contrast, we found no increase in T follicular helper cells (Tfh) and a lack of association between circulating Tfh and lymph node Tfh during AHI. Furthermore, early B cell depletion, particularly in resting memory B cells, was observed in blood but not in lymph nodes during AHI. Additionally, during AHI, plasmacytoid dendritic cell activation was increased in lymph nodes but not in blood. These findings suggest that certain immune cell phenotypes and dynamics are unique in lymph nodes compared to blood during AHI. Understanding the immune cell alteration in these compartments during AHI may help define the mechanisms leading to lack of immune control in natural HIV infection.
急性HIV感染(AHI)的先天、细胞和体液免疫在决定免疫和病理结果中起着至关重要的作用。然而,对AHI期间不同区室免疫细胞动力学的了解是有限的。在这项研究中,我们使用流式细胞术对来自RV254泰国AHI队列、RV304泰国慢性HIV感染队列和HIV阴性个体的匹配血液和淋巴结样本的免疫细胞进行了表征。我们的结果显示,在AHI期间,pbmc和lnmc的CD4:CD8比值显著下降。同样,我们观察到AHI期间血液和淋巴结室中CD4+和CD8+ T细胞的免疫激活增加。相反,我们发现在AHI期间,T滤泡辅助细胞(Tfh)没有增加,循环Tfh和淋巴结Tfh之间缺乏关联。此外,AHI期间在血液中观察到早期B细胞耗竭,特别是静息记忆B细胞耗竭,但在淋巴结中未见。此外,AHI期间,淋巴结浆细胞样树突状细胞活化增加,但血液中没有。这些发现表明,与AHI期间的血液相比,淋巴结中的某些免疫细胞表型和动力学是独特的。了解AHI期间这些区室中免疫细胞的改变可能有助于确定导致自然HIV感染中缺乏免疫控制的机制。

Antiretroviral therapy (ART) has transformed HIV from a fatal disease into manageable circumstance. However, the HIV reservoirs remain a main barrier to complete cure. This review emphasized when, where and how the latency is established, with focus on various host factors and viral proteins. We highlight the importance of Tat and Rev in facilitating the export and stability of HIV latency. We discuss how transcription factors such as NFκB, NFAT, and Sp1 regulate HIV gene expression during T cell activation, while other factors like MRTFB, BACH2, FOXO1, HMGB1, SAMHD1, APOBEC3, TRIM5, Wnt/β-catenin and LEDGF/p75 also contribute to the persistence of reservoirs. Recent studies have also identified novel restriction and immune regulatory factors such as, LAPTM5, KRT72, and CARD8, directly or indirectly influencing HIV 1 latency. The advancements in CRISPR screening technology have also identified novel host factors, such as FBXO34, FTSJ3, TMEM178A, NICN1, PEBP1, ZNF304 and ORC1, that are associated with HIV-1 latency. These findings underscore the multifaceted nature of viral latency and ongoing need for research to develop effective strategies for viral eradication.
抗逆转录病毒疗法(ART)已将艾滋病毒从一种致命疾病转变为可控制的情况。然而,艾滋病毒储存库仍然是完全治愈的主要障碍。这篇综述强调了何时、何地以及如何建立潜伏期,重点是各种宿主因子和病毒蛋白。我们强调Tat和Rev在促进HIV潜伏期输出和稳定方面的重要性。我们讨论了转录因子如NFκB、NFAT和Sp1如何在T细胞活化过程中调节HIV基因表达,而其他因子如MRTFB、BACH2、fox01、HMGB1、SAMHD1、APOBEC3、TRIM5、Wnt/β-catenin和LEDGF/p75也有助于储存库的持久性。最近的研究还发现了新的限制和免疫调节因子,如LAPTM5、KRT72和CARD8,直接或间接影响HIV 1潜伏期。CRISPR筛选技术的进步还发现了与HIV-1潜伏期相关的新型宿主因子,如FBXO34、FTSJ3、TMEM178A、NICN1、PEBP1、ZNF304和ORC1。这些发现强调了病毒潜伏期的多面性,以及研究开发有效的病毒根除策略的持续需求。
