Vitamin D in the management of Childhood Atopic Dermatitis (eczema)

This study is testing whether daily vitamin D supplements can reduce the severity of moderate-to-severe eczema (atopic dermatitis) in children. Eczema is a common skin condition causing itchy, inflamed skin. Some research suggests low vitamin D levels may make eczema worse, and this study will compare 1000 IU of vitamin D3 daily with a placebo (inactive pill) over 3 months to see if there is a difference in eczema severity and quality of life. You may be eligible if: - Your child is between 2 and 16 years old - Your child has been diagnosed with atopic dermatitis (eczema) that meets standard diagnostic criteria - Your child has moderate-to-severe eczema at the time of entering the study (SCORAD score above 15) You may NOT be eligible if: - Your child is under 2 or over 16 years old - Your child has previously taken or is currently taking oral immunosuppressive medications (like cyclosporin, azathioprine, or methotrexate) - Your child has taken oral corticosteroids within the past 6 months - Your child has received intravenous immunoglobulin (IVIg) therapy within the past 2 years - Your child has hypercalcaemia (high calcium), high blood pressure, or takes anticonvulsant medications Talk to your doctor about whether this trial might be right for you.
