Abstract
Background and Purpose— Alkaline phosphatase (ALP) is associated with risk of adverse cardiovascular events in patients with kidney failure. However, there is little data about effects of ALP on stroke outcomes in patients with preserved kidney function. The study aimed to explore the association between serum ALP level and clinical outcomes after stroke in patients with preserved kidney function. Methods— We included 16 367 stroke patients with preserved kidney function from the China National Stroke Registry for current analysis. Serum ALP levels were tested by automated enzymatic method using unfrozen samples in each center. Participants were divided into 5 groups according to ALP quintiles. Composite end point comprised of recurrent stroke, myocardial infarction, other ischemic vascular events, and all-cause mortality. Poor functional outcome is defined as modified Rankin Scale score of 3 to 6. Multivariable logistic regression was used to evaluate the independent association of serum ALP with 1-year all-cause mortality, recurrent stroke, composite end point, and poor functional outcome. Results— The mean age of the included 16 367 patients was 63.9 years, and 63.3% of them were men. Among the top ALP quintile (>98.0 U/L), 1-year incidences of all-cause mortality, recurrent stroke, composite end point, and poor functional outcome were 12.6%, 5.7%, 14.4%, and 27.0%, respectively. Compared with the lowest ALP quintile (≤59.0 U/L), the adjusted odds ratios of the top quintile were 1.36 (1.10–1.68) for all-cause mortality, 1.45 (1.11–1.90) for stroke recurrence, 1.35 (1.12–1.63) for composite end point, and 1.36 (1.17–1.60) for poor functional outcome. There was no significant interaction between age, sex, or alcohol consumption and ALP ( P for interaction ≥0.10) for all outcomes. Conclusions— In patients with preserved kidney function, ALP may be an independent predictor of all-cause mortality, stroke recurrence, composite end point, and poor functional outcome after stroke.

Objective. To determine the association between serum total alkaline phosphatase (TAP) and mortality in African maintenance haemodialysis patients (MHD). Patients and Methods. The study enrolled a total of 213 patients on MHD from two dialysis centers in Johannesburg between January 2009 and March 2016. Patients were categorized into a low TAP group (≤112 U/L) versus a high TAP group (>112 U/L) based on a median TAP of 112 U/L. Results. During the follow-up period of 7 years, there were 55 (25.8...

Summary Background The usefulness of estimated glomerular filtration rate (eGFR) and albuminuria for prediction of cardiovascular outcomes is controversial. We aimed to assess the addition of creatinine-based eGFR and albuminuria to traditional risk factors for prediction of cardiovascular risk with a meta-analytic approach. Methods We meta-analysed individual-level data for 637 315 individuals without a history of cardiovascular disease from 24 cohorts (median follow-up 4·2–19·0 years) included...

Chronic kidney disease (CKD) is associated with an increased risk of both ischemic and hemorrhagic stroke. In addition to shared risk factors, this higher cerebrovascular risk is mediated by several CKD-associated mechanisms including platelet dysfunction, coagulation disorders, endothelial dysfunction, inflammation, and increased risk of atrial fibrillation. CKD can also modify the effect of treatments used in acute stroke and in secondary stroke prevention. We review the epidemiology and patho...

Background The CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) creatinine equation estimates glomerular filtration rate (GFR) more precisely than the MDRD (Modification of Diet in Renal Disease) Study equation. The risk implications of this equation have been compared with the MDRD Study equation in different demographic and clinical characteristics. However, whether a Chinese modification of this equation performs better than a Chinese modification of the MDRD Study equation in risk...

Background and Purpose—Higher serum alkaline phosphatase (ALP) and phosphate levels are associated with atherosclerotic disease and an increased risk of cardiovascular events. However, the association of ALP/phosphate with cerebral atherosclerosis and prognosis in patients with acute stroke is not well known. Methods—In 1034 patients with first-ever acute cerebral infarction, levels of ALP and phosphate were compared with (1) cerebral atherosclerosis and (2) poor long-term functional outcomes as...

Although serum alkaline phosphatase (ALP) levels have been associated with mortality from all-cause and from either ischemic or hemorrhagic stroke, no study has been published of the associations between ALP and the incidence of stroke. We therefore examined the associations of ALP with risk of stroke among Japanese, stratified by drinking status because ALP is known as an enzyme affected by alcohol consumption. We conducted a prospective cohort study of 10,754 Japanese subjects (4098 men and 66...

Abstract Background Vascular calcification is believed to be due to the conversion of vascular smooth muscle cells into osteoblast-like cells and is associated with mortality. Since hypertension and related mortality in Africans is a concern, we investigated associations between a marker of osteoblastic activity, alkaline phosphatase (ALP), and measures of arterial structure and function in hypertensive African men. Methods This study included 79 participants. We conducted 24h ambulatory blood p...

AIMS Elevated serum alkaline phosphatase (ALP) levels are associated with an increased risk of cerebrocardiovascular diseases. However, the associations of ALP with peripheral arterial disease (PAD) and outcomes in patients with acute ischemic stroke (AIS) are not well-known. METHODS We examined the association between ALP levels and the ankle-brachial index (ABI) in 2111 consecutive patients with AIS. A poor functional outcome was defined as a modified Rankin Scale (mRS) score of 3-6 at 3 month...

Alkaline phosphatase (ALP) is an enzyme that is expressed in a variety of tissues. Among the isoforms of ALP, bone-specific alkaline phosphatase (BAP) is used as a marker for evaluating bone metabolism. We investigated the clinical usefulness of the ratio of serum BAP to total ALP for the diagnosis of various disorders in general practice. We retrospectively analyzed the cases of 107 Japanese patients whose serum BAP levels were exam-ined, focusing on clinical characteristics. We observed that t...

Cardiovascular calcification (CVC) is associated with increased morbidity and mortality. It develops in several diseases and locations, such as in the tunica intima in atherosclerosis plaques, in the tunica media in type 2 diabetes and chronic kidney disease, and in aortic valves. In spite of the wide occurrence of CVC and its detrimental effects on cardiovascular diseases (CVD), no treatment is yet available. Most of CVC involve mechanisms similar to those occurring during endochondral and/or i...

Objective Higher serum alkaline phosphatase (sALP) levels associate with a poor prognosis in maintenance hemodialysis patients. However, little is known about the meaning of lower sALP in this population. We hypothesized that lower sALP concentrations may express nutritional status and survival accordingly.

Here, we tested the hypothesis that TNAP (tissue nonspecific alkaline phosphatase) modulates vascular responsiveness to norepinephrine. In the isolated, Tyrode's-perfused rat mesentery, 50 µmol/L of L-p-bromotetramisole (L-p-BT; selective TNAP inhibitor, Ki=56 µmol/L) significantly reduced TNAP activity and caused a significant 9.0-fold rightward-shift in the norepinephrine concentration versus vasoconstriction relationship. At 100 µmol/L, L-p- BT further reduced mesenteric TNAP activity and cau...

Background Alkaline phosphatase (ALP) has been implicated to be associated with poor outcome in ischemic stroke patients, yet its role in aneurysmal subarachnoid hemorrhage (aSAH) patients is unknown. The current study aimed to investigate the on-admission and short-term variation trend of ALP levels in aSAH patients as well as its associations with vasospasm, delayed cerebral ischemia (DCI), and outcome after aSAH.

Abstract Object Ischemic stroke readmission within 90 days of hospital discharge is an important quality of care metric. The readmission rates of ischemic stroke patients are usually higher than those of patients with other chronic diseases. Our aim was to identify the ischemic stroke readmission risk factors and establish a 90-day readmission prediction model for first-time ischemic stroke patients. Methods The readmission prediction model was developed using the extreme gradient boosting (XGbo...
