What is the long-term effectiveness in people with celiac disease of following a gluten-free dietary pattern on hematological variables related to iron deficiency anemia?
For most children and adults with celiac disease, studies report that compliance with a gluten-free dietary pattern results in significant improvements in hematological parameters including serum hemoglobin, iron, ferritin, mean corpuscular volume, mean corpuscular hemoglobin and red cell distribution width. Recovery of anemia (normalization of hemoglobin concentrations) generally occurs within six months, while recovery from iron deficiency (normalization of ferritin concentrations) may take longer than one year. Iron supplementation in the form of a multi-vitamin with iron or additional therapeutic doses of iron may be necessary to achieve normal values of these hematological variables within these time periods.
- Grade I means there is Good/Strong evidence supporting the statement;
- Grade II is Fair;
- Grade III is Limited/Weak;
- Grade IV is Expert Opinion Only;
- Grade V is Not Assignable.
- High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
- Moderate (B) means we are moderately confident in the effect estimate;
- Low (C) means our confidence in the effect estimate is limited;
- Very Low (D) means we have very little confidence in the effect estimate.
- Ungraded means a grade is not assignable.
