AI Article Synopsis
- Cardiovascular diseases and infectious diseases are leading causes of death among patients with chronic kidney disease (CKD), with traditional risk factors for CVD not fully explaining their increased risk.
- Vitamin D deficiency is highlighted as a significant and potentially modifiable risk factor for CVD in CKD patients.
- The review examines emerging evidence linking low levels of 25-hydroxyvitamin D to higher risks of adverse cardiovascular outcomes and infections, while also discussing the non-calcemic roles of vitamin D in various tissues.
Article Abstract
Cardiovascular diseases (CVD) and infectious diseases represent the two most important causes of death in patients with chronic kidney disease (CKD). The traditional risk factors of CVD do not appear to account sufficiently for the increased risk of CVD in patients with CKD, and vitamin D deficiency appears to be an important non-traditional, and potentially modifiable, CVD risk factor in this patient population. 25-Hydroxyvitamin D (25(OH)D) is converted to its biologically active form, 1,25-dihydroxyvitamin D (1,25(OH)(2)D), by the enzyme 1α-hydroxylase in the kidneys. The recent discovery that many extrarenal tissues also possess both the 1α-hydroxylase enzyme and the vitamin D receptors has provided new insights into the important physiologic autocrine and paracrine roles of vitamin D in various tissues and organs that are mainly dependent on the availability of 25(OH)D from the circulating plasma. Accordingly, the present review focuses on the rapidly expanding body of clinical and experimental evidence that supports a strong association between 25(OH)D deficiency/insufficiency and the risk of adverse CVD outcomes and infectious diseases as well as on the non-calcemic autocrine and paracrine actions of vitamin D both in the general population and in patients with CKD.

Background: Vitamin D is thought to play a role in the development of migraine, but the nature of the relationship is still not fully understood. Although some studies have shown an association between vitamin D deficiency and migraine, other studies have had inconsistent or inconclusive results. Therefore, further research is needed to better understand the relationship between vitamin D and migraine headaches.

Autosomal recessive hypophosphatemic rickets type 2 (ARHR2) is an uncommon hereditary form of rickets characterised by chronic renal phosphate loss and impaired bone mineralisation. This results from compound heterozygous or homozygous pathogenic variants in ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), a key producer of extracellular inorganic pyrophosphate (PPi) and an inhibitor of fibroblast growth factor23 (FGF23). ENPP1 deficiency impacts FGF23 and increases its activity.

Background: Diagnosis of Alzheimer's disease (AD) via MRI is costly and can be limited by regional availability. With the recent advancements and discovery of amyloid in the retina, diagnosis of AD and the effect of AD pathology on the retina is becoming well characterized. However, the prevalence of vascular contributions to cognitive impairment and dementia (VCID) and its effects on the retina are less well known.

Background: Brain endothelial cell (EC) stress, including that induced by vascular amyloid β (Aβ) deposits in cerebral amyloid angiopathy (CAA) and Alzheimer's disease (AD), contributes to cerebral blood flow impairment, blood brain barrier (BBB) damage, neurovascular unit dysfunction, microhemorrhages and hypoperfusion, precipitating neurodegeneration and neuroinflammation processes. Epidemiological and experimental evidence suggests that hyperhomocysteinemia (Hhcy) contributes to increasing AD risk as well as CAA pathology. However, the cellular and molecular mechanisms through which Aβ and Hhcy drive EC and BBB dysfunction, whether the molecular effects of these challenges are additive or independent, and possible therapeutic strategies, remain to be determined.
