BACKGROUND:Evidence regarding the association between HIV viral load (VL) and hypertension is inconsistent. In this study, we investigated the relationship using viremia copy-years (VCY), a cumulative measure of HIV plasma viral burden.,METHODS:Data were analyzed for 686 PLWH in the Florida Cohort Study who had at least five years of VL data before the baseline. VL data were extracted from Enhanced HIV/AIDS Reporting System (eHARS) and used to define peak VL (pVL), recent VL (rVL), and undetectable VL (uVL: rVL<50copies/mL). A five-year VCY (log10 copy × years/mL) before the baseline investigation was calculated and divided into 5 groups (<2.7, 2.7-3.7. 3.8-4.7, 4.8-5.7 and >5.7) for analysis. Hypertension was determined based on hypertension diagnosis from medical records. Multivariable logistic regression was used for association analysis.,RESULTS:Of the total sample, 277 (40.4%) participants were hypertensive. Compared to the participants with lowest VCY (<2.7 log10 copy × years/mL), the odds ratios (OR) and 95% confidence interval [95% CI] for hypertension of the remaining four groups, in order, were 1.91 [1.11, 3.29], 1.91 [1.03, 3.53], 2.27 [1.29, 3.99], and 1.25 [0.65, 2.42], respectively, controlling for confounders. The association was independent of pVL, rVL, and uVL, each of which was not statistically significant associations with hypertension.,CONCLUSION:Persistent HIV infection is a risk factor for hypertension among PLWH. Information provided by VCY is more effective than single time-point VL measures in investigating HIV infection-hypertension relationship. Findings of this study support the significance of continuous viral suppression in hypertension prevention among PLWH.


背景: 关于 HIV 病毒载量 (VL) 和高血压之间关系的证据是不一致的。在这项研究中,我们使用病毒血症拷贝-年 (VCY) 调查关系,VCY 是 HIV 血浆病毒负担的累积测量。,方法: 对佛罗里达队列研究中 686 例 PLWH 的数据进行了分析,该研究在基线前至少有 5 年的 VL 数据。从增强型艾滋病毒/艾滋病报告系统 (eHARS) 中提取 VL 数据,用于定义峰值 VL (pVL) 、近期 VL (rVL) 和不可检测的 VL (uVL: rVL<50 拷贝/mL)。计算基线调查前 5 年 VCY (log10 拷贝 × 年/mL),分为 5 组 (<2.7,2.7-3.7。3.8-4.7 、 4.8-5.7 和> 5.7) 进行分析。根据病历的高血压诊断确定高血压。使用多变量 logistic 回归进行关联分析。结果: 在总样本中,277 (40.4%) 参与者患有高血压。与 VCY 最低 (<2.7 log10 拷贝 × 年/mL) 的参与者相比,其余四组高血压的比值比 (OR) 和 95% 置信区间 [95% CI],依次为 1.91 [1.11,3.29],1.91 [1.03,3.53],2.27 [1.29,3.99],和 1.25 [0.65,2.42],分别控制混杂因素。该相关性独立于 pVL 、 rVL 和 uVL,三者与高血压的相关性无统计学意义。结论: 在 PLWH 中,HIV 持续感染是高血压的危险因素。VCY 提供的信息在调查 HIV 感染-高血压关系方面比单一时间点 VL 措施更有效。本研究结果支持持续病毒抑制在 PLWH 高血压预防中的意义。

METHODS:BACKGROUND:Hypertensive disorders of pregnancy (HDP) increase cardiovascular disease (CVD) risk. Pregnancy morbidities, including preeclampsia, and CVD are common in systemic lupus erythematosus (SLE). Possible connections are important to explore. In a population-based cohort, we investigated whether HDP is associated with a higher risk of cardiovascular outcomes separately in SLE and non-SLE to examine the role of SLE. METHODS:We identified first singleton births in the Medical Birth Register (1987-2012) among mothers with SLE and a large general population comparison group. Discharge diagnoses for HDP, cardiovascular outcomes, and hypertension in the Patient Register were identified using ICD codes. We estimated adjusted hazard ratios and 95% confidence intervals (HR, 95% CI) of the association between HDP and outcomes, in separate models in women with and without SLE. We then evaluated additive and multiplicative effect modification using relative excess risk due to interaction and Cox models jointly accounting for SLE and HDP, respectively. Mediation analysis estimated the proportion of the association between SLE and outcome explained by HDP. RESULTS:HDP were more common in SLE pregnancies (20% vs 7%). In SLE, HDP were associated with a two-fold higher rate of cardiovascular outcomes and three-fold higher rate of incident hypertension. HDP mediated 20% of the latter association. In women without SLE, HDP was associated with higher hypertension incidence later in life. CONCLUSION:In women with and without SLE, HDP were associated with a three-fold higher rate of hypertension. In SLE, women with HDP developed cardiovascular outcomes twice as often as women without HDP.

METHODS:BACKGROUND:'Neuronal precursor cell expressed developmentally down-regulated 4-like' (NEDD4L) is considered a candidate gene for hypertension-both functionally and genetically-through the regulation of the ubiquitination of the epithelial sodium channel (ENaC). This study explores the relationship between genetic variation in NEDD4L and hypertension with chronic kidney disease (CKD) in the southeastern Han Chinese population. METHODS:We recruited 623 CKD patients and measured ambulatory blood pressure monitoring (ABPM), and the rs4149601 and rs2288774 polymorphisms in NEDD4L were genotyped using qPCR. RESULTS:For rs4149601, significant differences in genotype frequencies in an additive model (GG vs GA vs AA) were observed between normotensive patients and hypertensive patients when hypertension was classified into ambulatory hypertension, clinical hypertension and ambulatory systolic hypertension (P = 0.038, 0.005 and 0.006, respectively). In a recessive model (GG+GA vs AA), the frequency of the AA genotype of rs4149601 in the hypertension groups were all higher than that in the normotensive groups. The genotype distribution of rs2288774 did not differ significantly between the normotensive and hypertensive patients. In both the full cohort and the propensity score matching (PSM) cohort, the AA genotype of rs4149601 (compared to the GG+GA genotype group) was independently correlated with ambulatory hypertension, clinical hypertension and ambulatory systolic hypertension by multivariate logistic regression analysis. CONCLUSIONS:The present study indicates that the AA genotype of rs4149601 associates with hypertension in CKD. Consequently, the rs4149601 A allele might be a risk factor for hypertension with CKD.

METHODS:BACKGROUND:The burden of hypertension in many low-and middle-income countries is alarming and requires effective evidence-based preventative strategies that is carefully appraised and accepted by key stakeholders to ensure successful implementation and sustainability. We assessed nurses' perceptions of a recently completed Task Shifting Strategy for Hypertension control (TASSH) trial in Ghana, and facilitators and challenges to TASSH implementation. METHODS:Focus group sessions and in-depth interviews were conducted with 27 community health nurses from participating health centers and district hospitals involved in the TASSH trial implemented in the Ashanti Region, Ghana, West Africa from 2012 to 2017. TASSH evaluated the comparative effectiveness of the WHO-PEN program versus provision of health insurance for blood pressure reduction in hypertensive adults. Qualitative data were analyzed using open and axial coding techniques with emerging themes mapped onto the Consolidated Framework for Implementation Research (CFIR). RESULTS:Three themes emerged following deductive analysis using CFIR, including: (1) Patient health goal setting- relative priority and positive feedback from nurses, which motivated patients to make healthy behavior changes as a result of their health being a priority; (2) Leadership engagement (i.e., medical directors) which influenced the extent to which nurses were able to successfully implement TASSH in their various facilities, with most directors being very supportive; and (3) Availability of resources making it possible to implement the TASSH protocol, with limited space and personnel time to carry out TASSH duties, limited blood pressure (BP) monitoring equipment, and transportation, listed as barriers to effective implementation. CONCLUSION:Assessing stakeholders' perception of the TASSH implementation process guided by CFIR is crucial as it provides a platform for the nurses to thoroughly evaluate the task shifting program, while considering the local context in which the program is implemented. The feedback from the nurses informed barriers and facilitators to implementation of TASSH within the current healthcare system, and suggested system level changes needed prior to scale-up of TASSH to other regions in Ghana with potential for long-term sustainment of the task shifting intervention. TRIAL REGISTRATION:Trial registration for parent TASSH study: NCT01802372. Registered February 27, 2013.
