Time to Revise ImproveCareNow Micronutrient Recommendations

With ImproveCareNow, there have been efforts to minimize variation in care.  As such, there have been suggestions to monitor labs like vitamin D, vitamin B12, and folate routinely. I have voiced concern that some of this testing is unnecessary.  For vitamin B12, deficiency in pediatrics is rare; at risk populations include those with extensive small bowel resections, gastric resections or strict vegan diet.

A recent article (J Fritz et al. Inflamm Bowel Dis 2019; 25: 445-59) which is a systematic review of micronutrients in pediatric inflammatory bowel disease provides further support for the approach of less testing.

Key points:

  • A total of 39 studies were included in the final review (2903 subjects, 1115 controls)
  • Iron deficiency and vitamin D deficiency are common in pediatric patients with IBD
  • Vitamin B12 and folate deficiency are rare
  • Zinc deficiency is uncommon but increased in patients with Crohn’s disease compared to healthy controls.
  • The authors recommend routine (at least yearly) testing for iron, vitamin D and zinc and that there is “insufficient evidence to support routine screening for other micronutrient deficiencies.”

My take: Except in patients with surgical resections and in those with unusual diets (eg. vegan), routinely checking vitamin B12, folate and most other micronutrients is unnecessary & low value care.
