Рекомендації Зі Споживання Вітаміну D Для Здорового Населення Польщі Й Груп Ризику Дефіциту Вітаміну D

Abstract: Кальцитріол [1,25-дигідроксихолекальциферол (1,25(OH) 2 D)] є активною (гормональною) формою вітаміну D. За своєю дією він належить до широкої групи гормональних речовин, транскрипційних факторів генів білків-мішеней. На відміну від інших гормонів, що належать до цієї групи (андрогенів, естрогенів, глюкокортикоїдів, мінералокортикоїдів та прогестерону), синтез кальцитріолу обмежується наявністю/відсутністю його субстрату, 25-гідроксивітаміну D (25(OH)D). 25(OH)D є найбільш поширеним метаболітом вітаміну D.

“…However, high-dose supplementation without monitoring can lead to overdosing despite the lack of consensus in vitamin D toxicity threshold (100 or 150 ng/mL) [10][11]29 ]. Some experts suggest lower levels, such as 75-80 ng/mL 11,15 ], due to the increased risk of hypercalcemia in preterm infants 15,32 ]. Our results provide important information on why preterm infants present with isolated hypercalciuria, which can lead to nephrocalcinosis aggravated by high vitamin D levels 28,33 and a relatively 25(OH)D long half-life 11 .…”

“…Vitamin D dosage, safety, and effectiveness in preterm infants remain controversial and clear criteria for adequate supplementations have not been established. Some experts have suggested a new approach to vitamin D supplementation-monitored therapy 8,10,[14][15] ]. However, this approach's clinical significance and long-term effect have not been studied in most preterm populations.…”

“…However, if these conditions are not met, supplementation is recommended. The supply of vitamin D should be individually adjusted to each person, depending on various factors, such as age, body weight, sun exposure, diet, and the other factors of lifestyle [11].…”

“…According to the latest recommendations, the normal concentration of 25(OH)D in the plasma ranges from 20 to 80 ng/mL depending on location and age. A concentration below 10 ng/mL is referred to as severe vitamin D deficiency and above 100 ng/mL is considered toxic [11]. Severe deficiency can lead to the onset of rickets (especially in children), osteomalacia, myopathy, and hyperparathyroidism.…”

“…For this reason, a primary hypothesis of reverse causation is widely accepted and supported by a systemic meta-analysis and randomized controlled trials [8,9]. Ongoing studies point out potential benefits and minimal risks of Vitamin D supplementation, maintaining optimal and safe 25-hydroxy Vitamin D concentration in those groups unable of synthesizing enough Vitamin D in their skins [10].…”
