Iron deficiency/anemia due to iron deficiency in CD children and adolescents
Brief summary
Celiac disease in children is frequently associated with iron deficiency and/or iron deficiency anemia due to intestinal malabsorption and chronic inflammation. Although a gluten-free diet is the standard treatment and can restore iron balance over time, there is currently no clear evidence or consensus on the role and timing of iron supplementation in pediatric patients at diagnosis. Given the potential impact of anemia on growth and neurodevelopment, strategies that enable a faster correction of iron deficiency are clinically relevant. Sucrosomial® iron has shown improved absorption and gastrointestinal tolerability compared to conventional oral iron in adult celiac patients. This study aims to evaluate whether Sucrosomial® iron supplementation, in addition to a gluten-free diet, is more effective and safe than diet alone in achieving a faster normalization of hemoglobin and iron stores in children with newly diagnosed celiac disease. The primary objective of this randomized, double-blind, placebo-controlled, parallel-group study is to assess whether oral supplementation with Sucrosomial® iron, when added to a gluten-free diet (GFD), accelerates the normalization of iron stores and hemoglobin levels compared with GFD alone in school-age children and adolescents newly diagnosed with celiac disease presenting with hypoferritinemia and/or iron deficiency anemia. Target Study Population: Children and adolescents with celiac disease and iron deficiency or anemia due to iron deficiency. Study Duration Total study duration (per patient) will be about 6 months; total treatment duration (per patient) will be 6 months. Number of Patients: 60 planned Two typologies of patients will be included: with hypoferritinemia and with anemia due to iron deficiency. The randomization process will be stratified, so that: * 15 patients with hypoferritinemia receive active treatment and 15 patients receive placebo; * 15 patients with anemia due to iron deficiency receive active treatment and 15 patients receive placebo. The age of patients will also be considered for the randomization (to assign the correct number of product bottles).
Interventions
Patients with hypoferritinemia (no anemia): * From 8 years until development (Tanner stage \<=3): 1 ml of Sideral forte® VERUM drops, equal to 14 mg of iron element; * From development (Tanner stage \>3) up to 18 years: 2 ml of Sideral forte® VERUM drops, equal to 28 mg of iron element.
Patients with hypoferritinemia (no anemia): * From 8 years until development (Tanner stage \<=3): 1 ml/day of PLACEBO drops; * From development (Tanner stage \>3) up to 18 years: 2 ml/day of of PLACEBO drops.

Masking description
Patients will be randomly assigned to one of the following treatment groups: * Sideral forte verum drops for oral intake in addition to GFD. * Sideral forte matching placebo drops for oral intake in addition to GFD. Randomization will be stratified in order to reach a balanced enrolment between patients with hypoferritinemia and patients with anemia due to iron deficiency. Patients will start the study treatment simultaneously with GFD start, after their eligibility is confirmed at Visit 1 (screening) and will continue for 6 months. All patients will be treated with GFD that, so far, is considered the Standard of Care for CD. The Principal Investigator will receive a study treatment identification key in the form of a sealed envelope containing the kit number (i.e. Kit code A-004 or Kit code B-001, etc.) and the corresponding treatment. The envelope may be opened only in case of an emergency where the identification of the study treatment assigned to the patient needs to be disclosed
Intervention model description
