[PMID: 34088274 PMCID: PMC8176711 DOI: 10.1186/s12872-021-02081-8] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Accepted: 05/25/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The morning blood pressure surge (MBPS) is related to an exaggerated risk of cardiovascular diseases and mortality. With increasing attention on circadian change in blood pressure and extensive use of ambulatory blood pressure monitoring (ABPM), chronotherapy that administration of medication according to biological rhythm, is reported to improve cardiovascular outcomes. The aim of this study is to evaluate the influence of chronotherapy of antihypertensive drugs upon MBPS in hypertensive patients. METHODS A search strategy was applied in Ovid MEDLINE, EMBASE, Cochrane (Wiley) CENTRAL Register of Controlled Trials, Cochrane Database of Systematic Reviews, and the Chinese Biomedical literature database. No language and date restrictions. Randomized controlled trials (RCT) assessing the efficacy of evening and morning administration of the same medications in adult patients with primary hypertension were included. RESULTS A total of ten trials, comprising 1724 participants with a mean age of 61 and 51% female, were included in this study. Combined analysis observed significant reduction of MBPS (- 5.30 mmHg, 95% CI - 8.80 to - 1.80), night-time SBP (- 2.29 mmHg, 95% CI - 4.43 to - 0.15), night-time DBP (- 1.63 mmHg, 95 %CI - 3.23 to - 0.04) and increase in night blood pressure dipping (3.23%, 95% CI 5.37 to 1.10) in evening dosage compared with traditional morning dosage of blood pressure-lowering drugs. No significant difference was found in the incidence of overall adverse effects (RR 0.65, 95% CI 0.30 to 1.41) and withdrawal due to adverse effects (RR 0.95, 95% CI 0.53 to 1.71). CONCLUSIONS Our study suggested that evening administration of antihypertensive medications exerted better blood pressure-lowering effect on MBPS compared with conventional morning dosage. Safety assessment also indicated that the evening regimen did not increase the risk of adverse events. However, endpoint studies need to be carried out to confirm the significance and feasibility of this treatment regimen in clinical practice.

[PMID: 33279870 DOI: 10.1016/j.coph.2020.10.014] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Revised: 10/12/2020] [Accepted: 10/16/2020] [Indexed: 12/12/2022]
Abstract
Circadian rhythms impact cardiac and vascular pathophysiology, resulting in 24-hour patterning of symptoms and life-threatening/ending events (chronopathology), plus kinetics and dynamics of medications (chronopharmacology), resulting in administration-time differences in efficacy and safety. Scheduling medications according to circadian rhythm determinants (chronotherapy) can improve treatment effects, for example, before dinner/bedtime ingestion of cholesterol-lowering medications and acetylsalicylic acid, respectively, exerts enhanced control of hypercholesterolemia and after-awakening peak of platelet aggregation; bedtime ingestion of conventional hypertension medications optimizes normalization of sleep-time blood pressure (BP)-strongest independent BP marker of cardiovascular disease (CVD) risk-and most effectively prevents (chronoprevention) CVD morbidity and mortality. Exploration of chronotherapeutic strategies to improve management of cardiac arrhythmias and vascular pathophysiology is still awaited.

Restoration of nocturnal blood pressure dip and reduction of nocturnal blood pressure with evening anti-hypertensive medication administration in pediatric kidney transplant recipients: A pilot randomized clinical trial. Pediatr Transplant 2020; 24:e13854. [PMID: 33026142 DOI: 10.1111/petr.13854] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Revised: 08/23/2020] [Accepted: 08/29/2020] [Indexed: 12/17/2022]
Abstract
Non-dipping and nocturnal hypertension are commonly found during ABPM in pediatric kidney transplant recipients. These entities are independently associated with increased cardiovascular disease risk in adults. Kidney transplant recipients aged 5-21 years with eGFR > 30 mL/min/1.73 m2 and ABPM demonstrating non-dipping status and normal daytime BP were randomized to intervention (short acting BP medication added in the evening) or control (no medication change) in this pilot, randomized, open-label, blinded end-point clinical trial. ABPM, echocardiography, and PWV were performed at baseline, 3 months, and 6 months. The trial included 17 intervention and 16 control participants. Conversion to dipper status occurred in 53.3% vs 7.7% (P = .01) at 6 months for intervention and controls, respectively. Systolic dip was greater in the intervention group compared to controls (10.9 ± 4.5 vs 4.2 ± 4.6, P = .001), and average systolic nighttime BP was significantly lower in the intervention group (106 ± 8.3 vs 114.9 ± 9.5 mm Hg, P = .01) at 6 months. There were no significant differences in LVMI, PWV, or eGFR between groups. Within-group changes in the intervention group demonstrated improvements in non-dippers, dipping, systolic nighttime BP and nighttime BP load. Restoration of nocturnal dip and improvement in nocturnal BP were observed in the population following chronotherapy. Future studies are needed with larger sample sizes over a longer period of time to delineate the long-term effect of improved nocturnal dip on target organ damage.

Abstract
INTRODUCTION Office blood pressure measurements (OBPM), still used today for diagnosis and management of hypertension, fail to reveal clinically important features of the mostly predictable blood pressure (BP) 24 h pattern, and lead to >45% of individuals being misclassified. Current hypertension guidelines do not provide recommendation on when-to-treat, despite multiple prospective clinical trials documenting improved normalization of 24 h BP pattern and significant reduction in cardiovascular disease (CVD) events when hypertension medications are ingested at bedtime rather than upon waking. AREAS COVERED In this review, the authors discuss current evidence on the: (i) most relevant attributes of the 24 h BP pattern deterministic of CVD risk; (ii) asleep systolic BP (SBP) mean as the most significant therapeutic target for CVD risk reduction; (iii) ingestion-time differences in pharmacodynamics of BP-lowering medications as reported with high consistency in multiple clinical trials; and (iv) enhanced prevention of CVD events achieved by bedtime hypertension chronotherapy. EXPERT OPINION Several prospective trials consistently document asleep SBP mean and sleep-time relative SBP decline (dipping) constitute highly significant CVD risk factors, independent of OBPM. Bedtime, compared to customary upon-waking, hypertension chronotherapy reduces risk of major CVD events. Collectively, these findings call for new definition of true hypertension and, accordingly, its proper diagnosis and management.

Abstract
Multiple physiological variables change over time in a predictable and repetitive manner, guided by molecular clocks that respond to external and internal clues and are coordinated by a central clock. The kidney is the site of one of the most active peripheral clocks. Biological rhythms, of which the best known are circadian rhythms, are required for normal physiology of the kidneys and other organs. Chronodisruption refers to the chronic disruption of circadian rhythms leading to disease. While there is evidence that circadian rhythms may be altered in kidney disease and that altered circadian rhythms may accelerate chronic kidney disease (CKD) progression, there is no comprehensive review on chronodisruption and chronodisruptors in CKD and its manifestations. Indeed, the term chronodisruption has been rarely applied to CKD despite chronodisruptors being potential therapeutic targets in CKD patients. We now discuss evidence for chronodisruption in CKD and the impact of chronodisruption on CKD manifestations, identify potential chronodisruptors, some of them uremic toxins, and their therapeutic implications, and discuss current unanswered questions on this topic.

Abstract
Aim. To assess and compare the efficacy of combination antihypertension drugs influence with various dosage regimens during 24 hour, on the parameters of daily blood pressure (BP) profile, central aortic pressure (CAP) and vessel wall stiffness in arterial hypertension (AH) patients with ischemic stroke (IS).Material and methods. To the study, 177 AH patients included, with IS within last 4 weeks. All patients were randomized to 3 groups depending on the regimen of antihypertensive drugs combination intake during 24 hours. At baseline and in 12 months of therapy all patients underwent 24 hour BP monitoring (ABPM), CAP measurement and vessel wall stiffness evaluation. Results. In 8 weeks of antihypertension therapy, target pressure level achievement was significantly more common in b. i.d. valsartan (group 3) comparing to once daily in the morning (group 1) or evening (group 2) (p<0,05). In all groups there were statistically significant positive changes in ABPM, CAP and stiffness. Also, in the group 2 there was significantly (p<0,05) more prominent decrease of the main ABPM, CAP and stiffness parameters than in the group 1. Valsartan b. i.d. led to significantly more prominent (p<0,05) improvement of the main ABPM, CAP and stiffness parameters improvement comparing to both variants of its once daily regimens. In 12 months of chronopharmacotherapy, in all groups, there was significant (p<0,05) increase of “dipper” 24 hour BP profile patients. Differences of the groups of “dippers” and “non-dippers” by the 12th month of treatment were significant for 3rd and 1st (p=0,0004), 3rd and 2nd (p=0,04) groups with the benefit for group 3.Conclusion. Two times a day or only evening intake of valsartan with thiazidelike diuretic in the morning facilitated more significant improvement of the main parameters of ABPM, CAP and vascular wall rigidity comparing to just morning intake. B.i.d. valsartan regimen led to significantly (p<0,05) more commonly reached target BP level, improved normalization of 24 hour BP in most of patients, led to more significant improvement of the main ABPM, CAP and vascular stiffness parameters comparing to once daily morning or evening regimen.

Abstract
Diagnosis of hypertension-elevated blood pressure (BP) associated with increased cardiovascular disease (CVD) risk-and its management for decades have been based primarily on single time-of-day office BP measurements (OBPM) assumed representative of systolic (SBP) and diastolic BP (DBP) during the entire 24-hours span. Around-the-clock ambulatory blood pressure monitoring (ABPM), however, reveals BP undergoes 24-hours patterning characterized in normotensives and uncomplicated hypertensives by striking morning-time rise, 2 daytime peaks-one ~2-3 hours after awakening and the other early evening, small midafternoon nadir and 10-20% decline (BP dipping) in the asleep BP mean relative to the wake-time BP mean. A growing number of outcome trials substantiate correlation between BP and target organ damage, vascular and other risks is greater for the ABPM-derived asleep BP mean, independent and stronger predictor of CVD risk, than daytime OBPM or ABPM-derived awake BP. Additionally, bedtime hypertension chronotherapy, that is, ingestion of ≥1 conventional hypertension medications at bedtime to achieve efficient attenuation of asleep BP, better reduces total CVD events by 61% and major events (CVD death, myocardial infarction, ischaemic and haemorrhagic stroke) by 67%-even in more vulnerable chronic kidney disease, diabetes and resistant hypertension patients-than customary on-awaking therapy that targets wake-time BP. Such findings of around-the-clock ABPM and bedtime hypertension outcome trials, consistently indicating greater importance of asleep BP than daytime OBPM or ambulatory awake BP, call for a new definition of true arterial hypertension plus modern approaches for its diagnosis and management.
