High calcitriol level
WebParathyroid hormone stimulates calcitriol production in the kidney by increasing the synthesis of 1-α hydroxylase. Calcitriol has several important functions in the body. It maintains serum calcium levels by increasing calcium absorption in the gastrointestinal tract. It promotes healthy bone formation by the calcification of osteoid tissue. Web5 de abr. de 2024 · In addition, FGF23 decreases the serum levels of calcitriol by a double mechanism. On the one hand, it suppresses the expression of the CYP27B1 gene, thus limiting the synthesis of 1α-hydroxylase, and, on the other hand, it increases the expression of CYP24A1 and the synthesis of 24-hydroxylase, its main catabolic pathway.

In granulomatous disorders, the calcitriol level is not suppressed due to an atypical production of 1-alpha-hydroxylase by macrophages.
WebLow calcitriol levels is one of the earliest changes to occur in persons with early kidney failure. A high level of vitamin D 25-dihydroxy may occur when there is excess parathryoid hormone or when there are diseases, such as sarcoidosis or some lymphomas, that can make calcitriol outside of the kidneys. Medically Reviewed by: Colleen Ryan, MD WebJak1/Stat3 activation led to very high intact FGF23 levels in the plasma and lower PTH and total iron levels and higher calcitriol levels in female Jak1 S645P+/− mice (Fig. 1C‒F). Despite the very high intact FGF23 levels, female Jak1 S645P+/− mice showed normophosphaturia and a similar fractional excretion of phosphate to WT mice (Fig. 1 G, H).
