<p><strong>Background: </strong>Adherence to daily oral pre-exposure prophylaxis (PrEP) is low among African young women, and layered support strategies are needed to improve PrEP adherence in this population. We aimed to evaluate potentially scalable adherence-support strategies for young women aged 18-25 years who initiated PrEP in Johannesburg, South Africa.</p><p><strong>Methods: </strong>We conducted a sequential multiple-assignment randomised trial at Ward 21 of the Wits Reproductive Health and HIV Institute clinical research site, affiliated with University of the Witwatersrand, Johannesburg, South Africa. Participants were eligible if they were assigned female sex at birth, aged 18-25 years, not living with HIV, sexually active, newly initiating PrEP, had regular access to a mobile telephone, and could read. Using sequentially numbered, sealed, opaque envelopes containing group allocation, a staff member assigned enrolled participants (1:1) to receive one of two adherence-support interventions: once per week two-way SMS communication or participation in a WhatsApp peer-support group. Participants assigned to WhatsApp were put into groups with approximately 25 participants, during which they were prompted by staff facilitators to discuss any challenges with PrEP use or other events happening in their lives. The allocation sequence was generated by the data manager using random numbers with variable block sizes between 10 and 14. Only trial investigators were masked to participant intervention assignments; participants, people giving interventions, people assessing outcomes, and people analysing data were not masked to group assignment. All enrolled participants were offered PrEP (ie, co-formulated, once per day oral emtricitabine 200 mg and tenofovir disoproxil fumarate 300 mg). The primary outcome was high PrEP adherence at month 9, defined as concentration of tenofovir diphosphate on dried blood sample of 700 fmol per punch or more. At month 3, participants with low PrEP adherence were randomly assigned to a secondary, intensified intervention of issue-focused counselling once per month or drug-level feedback counselling based on PrEP drug concentrations at months 3 and 6. The protocol was registered at ClinicalTrials.gov (NCT04038060) and the trial is complete.</p><p><strong>Findings: </strong>Participants were enrolled and followed up between May 16, 2019, and Jan 25, 2022. From May 16, 2019, to Jan 29, 2021, 401 participants were screened and 360 were enrolled and initiated PrEP. 180 (50%) were randomly assigned to two-way SMS and 180 (50%) were randomly assigned to WhatsApp support groups. At month 9, 34 (20%) of 174 participants in the two-way SMS arm had tenofovir diphosphate 700 fmol per punch or more, compared with 32 (18%) of 174 in the WhatsApp arm (relative risk 1·06, 95% CI 0·69-1·64; p=0·78). At month 9, four (5%) of 76 participants in the drug-level feedback arm had tenofovir diphosphate 700 fmol per punch or more, compared
背景:非洲年轻女性对每日口服暴露前预防药物(PrEP)的依从性较低,因此需要采取分层支持策略来提高该人群对 PrEP 的依从性。我们旨在评估针对南非约翰内斯堡 18-25 岁开始接受 PrEP 的年轻女性可能采取的可扩展的依从性支持策略:我们在南非约翰内斯堡威特沃特斯兰德大学下属的威特斯生殖健康与艾滋病研究所临床研究基地 21 号病房进行了一项连续多次分配随机试验。只要出生时性别为女性、年龄在 18-25 岁之间、未感染 HIV、性生活活跃、刚开始使用 PrEP、经常使用移动电话且识字,就有资格参加试验。工作人员使用按顺序编号、密封的不透明信封(内含小组分配表),将登记的参与者(1:1)分配到两种依从性支持干预措施中的一种:每周一次的双向短信通信或参加 WhatsApp 同伴支持小组。被分配到 WhatsApp 群组的参与者被编入约 25 人的小组,在此期间,工作人员会提示他们讨论使用 PrEP 所面临的任何挑战或生活中发生的其他事件。分配顺序由数据管理员使用随机数生成,组块大小在 10 到 14 之间。只有试验调查人员对参与者的干预分配进行了蒙蔽;参与者、提供干预的人员、评估结果的人员和分析数据的人员均不对分组分配进行蒙蔽。所有参与试验的人员都接受了 PrEP(即共同配制、每天口服一次的恩曲他滨 200 毫克和富马酸替诺福韦二吡呋酯 300 毫克)。主要研究结果是第 9 个月时 PrEP 的高度依从性,即干血样本中的二磷酸替诺福韦浓度达到或超过 700 fmol/punch。在第 3 个月,PrEP 依从性低的参与者被随机分配到次要的强化干预中,即每月一次以问题为重点的咨询或根据第 3 个月和第 6 个月的 PrEP 药物浓度提供药物级别的反馈咨询。该方案已在ClinicalTrials.gov(NCT04038060)上注册,目前试验已经完成:参与者于 2019 年 5 月 16 日至 2022 年 1 月 25 日期间注册并接受随访。从 2019 年 5 月 16 日到 2021 年 1 月 29 日,401 名参与者接受了筛查,360 名参与者注册并开始使用 PrEP。180人(50%)被随机分配到双向短信群组,180人(50%)被随机分配到WhatsApp支持群组。第9个月时,双向短信组的174名参与者中有34人(20%)的二磷酸替诺福韦达到或超过700 fmol/punch,而WhatsApp组的174名参与者中有32人(18%)达到或超过700 fmol/punch(相对风险1-06,95% CI 0-69-1-64;P=0-78)。第9个月时,药物水平反馈组的76名参与者中有4人(5%)的二磷酸替诺福韦达到或超过700 fmol/punch,而每月咨询组的76名参与者中有3人(4%)达到或超过700 fmol/punch(1-33,0-31-5-76;P=0-70)。试验期间共报告了22起严重不良事件,但均被认为与试验无关:在南非约翰内斯堡的年轻女性中,PrEP 在不同干预措施下的依从性并无差异。未来需要研究是否以及如何在资源有限的环境中扩大对年轻女性的 PrEP 支持:美国国立卫生研究院。

This target product profile (TPP) highlights the minimal and optimal characteristics for ex-vivo and in-vivo cell and gene therapy-based products aimed at achieving an HIV cure (ie, durable antiretroviral-free viral control). The need for an effective, safe, scalable, affordable, accessible, and acceptable cure for HIV infection remains a major global priority. The possibilities for cell and gene therapy-based products for an HIV cure are rapidly expanding. In a multi-stakeholder consensus process of clinical experts and civil society, including representatives from low-income and middle-income countries, participants generally agreed on the optimal targets, whereas consensus on the minimal targets was not reached on every parameter. There was less agreement on the minimal targets for ex-vivo than in-vivo therapies given the complexity of ex-vivo interventions. The TPP is planned to be updated at regular intervals. Building a TPP, such as this one, is an important process for stakeholder engagement and aligning ambitions for the development of products that are acceptable to both clinicians and civil society.

BACKGROUNDRisk estimation is an essential component of cardiovascular disease prevention among people with HIV. We aimed to characterise how well atherosclerotic cardiovascular disease (ASCVD) risk scores used in clinical guidelines perform among people with HIV globally.METHODSIn this prospective cohort study leveraging REPRIEVE data, we included participants aged 40-75 years, with low-to-moderate traditional cardiovascular risk, not taking statin therapy. REPRIEVE participants were enrolled from sites in 12 countries across Global Burden of Disease Study (GBD) regions. We assessed the performance of the pooled cohort equations (PCE) risk score for ASCVD and the data-collection on adverse effects of anti-HIV drugs (D:A:D) risk score. We calculated C statistics, observed-to-expected (OE) event ratios, and Greenwood-Nam-D'Agostino goodness-of-fit (GND) statistics, overall and in subgroups by race, sex, and GBD regions (clustering low-income and middle-income countries and high-income countries). We did a recalibration for PCE risk score among people with HIV in high-income countries. REPRIEVE was registered with ClinicalTrials.gov, NCT02344290.FINDINGSWe included 3893 participants, recruited between March 26, 2015, and July 31, 2019. The median age was 50 years (IQR 45-55), with 2684 (69%) male and 1209 (31%) female participants. 1643 (42%) were Black or African American, 1346 (35%) participants were White, 566 (15%) were Asian, and 338 (9%) were recorded as other race. Overall, discrimination of the PCE risk score was moderate (C statistic 0·72 [95% CI 0·68-0·76]) and calibration was good (OE event ratio 1·11; GND p=0·87). However, calibration suggested overprediction of risk in low-income and middle-income countries and corresponding underprediction in high-income countries. When restricted to high-income countries, we found underprediction (OE event ratio >1·0) among women (2·39) and Black or African American participants (1·64). Findings were similar for the D:A:D risk score (C statistic 0·71 [0·65-0·77]; OE event ratio 0·89; p=0·68). Improved calibration of the PCE risk score in high-income countries was achieved by multiplying the original score by 2·8 in Black or African American women, 2·6 in women who were not Black or African American, and 1·25 in Black or African American men.INTERPRETATIONAmong the global cohort of people with HIV in REPRIEVE, the PCE risk score underpredicted cardiovascular events in women and Black or African American men in high-income countries and overpredicted cardiovascular events in low-income and middle-income countries. Underprediction in subgroups should be considered when using the PCE risk score to guide statin prescribing for cardiovascular prevention among people with HIV in high-income countries. Additional research is needed to develop risk scores accurate in predicting ASCVD among people with HIV in low-income and middle-income countries.FUNDINGUS National Institutes of Health, Kowa Pharmaceuticals Am
背景:风险评估是艾滋病毒感染者预防心血管疾病的重要组成部分。我们的目的是描述临床指南中使用的动脉粥样硬化性心血管疾病(ASCVD)风险评分在全球艾滋病毒感染者中的表现。方法:在这项利用REPRIEVE数据的前瞻性队列研究中,我们纳入了年龄在40-75岁之间、具有中低传统心血管风险、未接受他汀类药物治疗的参与者。REPRIEVE参与者来自全球疾病负担研究(GBD)区域的12个国家。我们评估了ASCVD的合并队列方程(PCE)风险评分和抗hiv药物不良反应(D:A:D)风险评分的数据收集的表现。我们计算了总体和按种族、性别和GBD地区(低收入和中等收入国家和高收入国家)分组的C统计量、观察-期望(OE)事件比和Greenwood-Nam-D'Agostino拟合优度(GND)统计量。我们对高收入国家艾滋病毒感染者的PCE风险评分进行了重新校准。reeve已在ClinicalTrials.gov注册,注册号NCT02344290。研究结果:我们纳入了3893名参与者,于2015年3月26日至2019年7月31日招募。中位年龄为50岁(IQR 45-55岁),男性2684人(69%),女性1209人(31%)。1643人(42%)为黑人或非裔美国人,1346人(35%)为白人,566人(15%)为亚洲人,338人(9%)为其他种族。总体而言,PCE风险评分的判别性中等(C统计值为0.72 [95% CI为0.68 ~ 0.76]),校准良好(OE事件比为1.11;接地p = 0·87)。然而,校准表明,低收入和中等收入国家的风险被高估,而高收入国家的风险被相应低估。当仅限于高收入国家时,我们发现女性(2.39)和黑人或非裔美国人(1.64)的OE事件比低于预测(0.1.1)。D:A:D风险评分结果相似(C统计值为0.71 [0.65 ~ 0.77];OE事件比0·89;p = 0·68)。通过将黑人或非裔美国女性的原始评分乘以2.8,非黑人或非裔美国女性的原始评分乘以2.6,黑人或非裔美国男性的原始评分乘以1.25,实现了高收入国家PCE风险评分的改进校准。在全球HIV感染者队列中,PCE风险评分低估了高收入国家女性和黑人或非裔美国男性的心血管事件,而高估了低收入和中等收入国家的心血管事件。在高收入国家,当使用PCE风险评分来指导他汀类药物在艾滋病毒感染者中预防心血管疾病时,应考虑亚组的预估不足。需要进一步的研究来制定准确预测低收入和中等收入国家艾滋病毒感染者ASCVD的风险评分。美国国立卫生研究院、美国科华制药公司、吉利德科学公司和ViiV医疗保健公司。

Improved calibration of the PCE risk score in high-income countries was achieved by multiplying the original score by 2·8 in Black or African American women, 2·6 in women who were not Black or African American, and 1·25 in Black or African American men.INTERPRETATIONAmong the global cohort of people with HIV in REPRIEVE, the PCE risk score underpredicted cardiovascular events in women and Black or African American men in high-income countries and overpredicted cardiovascular events in low-income and middle-income countries. Underprediction in subgroups should be considered when using the PCE risk score to guide statin prescribing for cardiovascular prevention among people with HIV in high-income countries. Additional research is needed to develop risk scores accurate in predicting ASCVD among people with HIV in low-income and middle-income countries.FUNDINGUS National Institutes of Health, Kowa Pharmaceuticals Am","PeriodicalId":48725,"journal":{"name":"Lancet Hiv","volume":"10 1","pages":""},"PeriodicalIF":16.1,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142991815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BACKGROUNDDolutegravir plus lamivudine has emerged as a preferred treatment for HIV; however, initiating this regimen without baseline resistance testing raises concerns about the potential presence of pretreatment lamivudine resistance. We aimed to evaluate the efficacy of dolutegravir plus lamivudine in the absence of information on baseline resistance testing in treatment-naive people with HIV.METHODSWe did an open-label, non-inferiority, single-centre, phase 4, randomised controlled study (D2ARLING), designed to assess the efficacy and safety of dolutegravir plus lamivudine in treatment-naive people with HIV with no available baseline resistance testing. We included participants aged 18 years or older with HIV-1 diagnosis who were naive to antiretroviral therapy and had no baseline genotypic resistance testing result available. We randomly assigned (1:1) participants to receive dolutegravir 50 mg plus lamivudine 300 mg or a three-drug regimen including dolutegravir 50 mg plus tenofovir disoproxil fumarate 300 mg and either emtricitabine 200 mg or lamivudine 300 mg. Randomisation was stratified by baseline HIV-1 RNA (≤100 000 vs >100 000 copies per mL) and CD4 cell count (<200 vs ≥200 cells per μL). Per protocol, we performed genotypic drug-resistance testing on day 1 and it remained double-masked throughout the study, simulating a scenario of inaccessibility of baseline resistance testing. The primary endpoint was the proportion of participants with plasma HIV-1 RNA less than 50 copies per mL at week 48 (intention-to-treat exposed analysis via the Snapshot algorithm) with prespecified non-inferiority margin of 10%. This trial is registered with ClinicalTrials.gov (NCT04549467).FINDINGSBetween Nov 17, 2020, and Aug 31, 2022, 214 participants were randomly assigned to and treated with dolutegravir plus lamivudine (n=106) or dolutegravir plus tenofovir disoproxil fumarate and either emtricitabine or lamivudine (n=108). Median age of participants was 31 years (IQR 26-39) and 49 (23%) were female. At baseline, 66 (31%) of participants had an HIV-1 RNA viral load of more than 100 000 copies per mL, and 44 (21%) had a CD4 T-cell count of less than 200 cells per μL. At week 48, 97 (92%) of 106 participants in the dolutegravir plus lamivudine group and 96 (89%) of 108 participants in the dolutegravir plus tenofovir disoproxil fumarate with either emtricitabine or lamivudine group had HIV-1 RNA of less than 50 copies per mL (difference 2·62%; 95% CI -5·3 to 10·6), showing non-inferiority of dolutegravir plus lamivudine to the three-drug regimen. None of the participants in the dolutegravir plus lamivudine group and two in the control group had protocol-defined virological failure, and none developed treatment-emergent resistance mutations to any of the study drugs. Overall adverse event rates were similar between arms. Less than 1% of participants in both groups were discontinued due to adverse events.INTERPRETATIONThis study provides evidence supporti
dolutegravir +拉米夫定已经成为HIV的首选治疗方案;然而,在没有基线耐药试验的情况下启动该方案引起了对潜在的预处理拉米夫定耐药的担忧。我们的目的是在缺乏基线耐药检测信息的情况下,评估多替格拉韦加拉米夫定在未接受治疗的HIV感染者中的疗效。方法:我们进行了一项开放标签、非效性、单中心、4期随机对照研究(D2ARLING),旨在评估多替格拉韦联合拉米夫定在未接受治疗且无基线耐药检测的HIV感染者中的疗效和安全性。我们纳入了年龄在18岁或以上的HIV-1诊断患者,他们未接受抗逆转录病毒治疗,并且没有基线基因型耐药测试结果。我们随机分配(1:1)参与者接受多替重力韦50 mg +拉米夫定300 mg或三药方案,包括多替重力韦50 mg +富马酸替诺福韦二吡酯300 mg和恩曲他滨200 mg或拉米夫定300 mg。随机化通过基线HIV-1 RNA(≤100000 vs bb0 100000拷贝/ mL)和CD4细胞计数(<200 vs≥200细胞/ μL)分层。根据方案,我们在第1天进行基因型耐药测试,并在整个研究过程中保持双掩码,模拟无法获得基线耐药测试的情况。主要终点是48周时血浆HIV-1 RNA低于50拷贝/ mL的参与者比例(通过Snapshot算法进行意向治疗暴露分析),预设的非劣效边际为10%。该试验已在ClinicalTrials.gov注册(NCT04549467)。结果:在2020年11月17日至2022年8月31日期间,214名参与者被随机分配到多替重力韦加拉米夫定(n=106)或多替重力韦加富马酸替诺福韦二吡酯和恩曲他滨或拉米夫定(n=108)治疗。参与者的中位年龄为31岁(IQR 26-39), 49岁(23%)为女性。在基线时,66名(31%)参与者的HIV-1 RNA病毒载量超过100,000拷贝/ mL, 44名(21%)参与者的CD4 t细胞计数低于200个/ μL。在第48周,多替重力韦加拉米夫定组106名参与者中有97名(92%)和多替重力韦加富马酸替诺福韦二氧吡酯与恩曲他滨或拉米夫定组108名参与者中有96名(89%)的HIV-1 RNA小于50拷贝/ mL(差异为2.62%;95% CI为- 5.3 ~ 10.6),显示多替格拉韦联合拉米夫定对三药方案的非劣效性。dolutegravir +拉米夫定组的参与者和对照组的两名参与者没有出现协议定义的病毒学失败,也没有出现对任何研究药物的治疗产生的耐药突变。两组间总的不良事件发生率相似。两组中均有不到1%的受试者因不良事件而停药。解释:本研究提供了证据,支持在没有基线耐药测试的初始治疗个体中,与首选的三药方案相比,多替格拉韦加拉米夫定的非劣效性。这些发现表明,在低频率或怀疑对这些药物传播性耐药的环境中,基线耐药检测可能不是开始使用多替格拉韦加拉米夫定治疗的必要条件。FUNDINGViiV医疗保健。
