Vitamin D Deficiency in Patients with Pancreatitis: Is Vitamin D Replacement Required?

Clinical findings have shown that approximately 40% of patients with pancreatitis, acute or chronic, have severe vitamin D deficiency; this can reach up to 60% of patients with chronic pancreatitis.

These findings raise an important question: Is vitamin D deficiency a cause or a result of pancreatitis? The answer(s) to this question is clinically important given that high oral doses of vitamin D supplementation are widely prescribed for individuals with vitamin D deficiency.

Considering that there is active conversion of 25(OH)D3 to 1,25(OH)2D3 by activated macrophages in tissues undergoing inflammation, that elevation of the blood levels of 1,25(OH)2D3 levels can cause hypercalcemia, that hypercalcemia can precipitate pancreatitis, that excessive use of vitamin D supplementation can cause acute pancreatitis.
