Vitamin D Status in Inflammatory Bowel Disease (vdsinibd)

April 5, 2018 updated by: mohammed ragab, Assiut University
Inflammatory bowel disease (IBD), comprising crohn's disease (CD) and ulcerative colitis (UC), is a a chronic, relapsing-remitting systemic disease. Vitamin D is a secosteroid hormone that possesses immunomodulatory properties and has been demonstrated to potentially influence inflammatory bowel disease (IBD) pathogenesis and activity.

Study Overview

Detailed Description

Inflammatory bowel disease (IBD), comprising crohn's disease (CD) and ulcerative colitis (UC), is a a chronic, relapsing-remitting systemic disease and it is increasing sharply with rapidly increasing proportion in developing countries., and the common medications are not effective for most patients.The key underlying pathogenic mechanisms for both diseases is a dysregulated host immune response to commensal intestinal flora in genetically susceptible individuals.Vitamin D is a fat-soluble vitamin, a secosteroid hormone whose active form, calcitriol or 1,25-dihydroxyvitaminD3 (1,25(OH)2D3) plays important roles in immune regulation, particularly involving the innate immune system, cell differentiation and intercellular adhesion, promotes the production of anti-microbial peptides, including β-defensins and cathelicidins, the shift towards Th2 immune responses, and regulates autophagy and epithelial barrier integrity.The relationship between vitamin D deficiency and IBD is bidirectional that vit D with its immunomodulatory effects influence IBD pathogenesis and activity and IBD itself can lead to vitamin D deficiency.Vitamin D deficiency has associated with increased IBD activity scores, lower quality-of-life, an increased risk of IBD-related surgery and increased hospitalizations.[4]. Vitamin D downregulate powerful proinflammatory cytokines, such as TNF, which enhance the durability of anti-TNF therapy in IBD and its deficency has been found to be associated with earlier cessation of anti-TNFα therapy( loss of response to biologic therapy.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
ACTIVE_COMPARATOR: Group A
patients with vitamin D deficiency are investigated for serum total 25 hydroxycholecalciferol 25(OH) vitamin D,complete blood count (CBC),serum calcium level ,serum phosphurus level,erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),serum creatinine ,serum albumin level,seum alanine aminotransferase and serum potassium level.
Quantitative measurement of serum total 25(OH) vitamin D by ELISA. Fasting (6-8 hours), venous blood samples(10ml) are collected from participants in the morning and after centrifugation, the serum are preserved in the deep freezer at -20 c. Serum levels will be determined by using commercially available kits.
for measurement of hemoglobin level and white blood cell count percent of neutrophils ,lymphocytes and esoinphils
measurement of total calcium level after correction with albumin level as it is closely related to vitamin d with its effects on its level
it is an indicator of activity in inflammatory bowel disease
it is an indicator for increased possibility of infections
for assessment of renal function
for possibility of malabsorbtion in patients with inflammatory bowel disease
for assessment of liver function
indicator for hypokalemia increased in patients with diarrhea as result of inflammatory bowel disease
measurement of phosphurus level as it is closely related to vitamin d with its effects on its level
ACTIVE_COMPARATOR: Group B
patients with vitamin D insufficiency are investigated for serum total 25 hydroxycholecalciferol 25(OH) vitamin D,complete blood count (CBC),serum calcium level ,serum phosphurus level,erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),serum creatinine ,serum albumin level,seum alanine aminotransferase and serum potassium level.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
vitamin D deficency in Inflammatory Bowel Disease
Time Frame: one day
serum total 25(OH) vitamin D is measured in patients with Inflammatory Bowel Disease (either ulcerative colitis or crohns disease) by Quantitative measurement by ELISA with Fasting (6-8 hours), venous blood samples will be collected from participants in the morning. Serum 25(OH)D levels of less than 20 ng/mL indicate vitamin D deficiency.
one day
vitamin D insufficiency in Inflammatory Bowel Disease
Time Frame: one day
by Quantitative measurement of serum total 25(OH) vitamin D by ELISA with Fasting (6-8 hours), venous blood samples will be collected from participants in the morning. Serum 25(OH)D levels between 21 and 29 ng/mL indicate vitamin D insufficiency.
one day

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
the severity of Inflammatory Bowel Disease with its relation to vitamin D level the severity is detected by a composite clinical and biomarker index called the Seo index
Time Frame: one day

severity of Inflammatory Bowel Disease is detected by a composite clinical and biomarker index that combines the clinical symptoms including fever, bleeding and stool frequency with biomarkers including C-reactive protein (CRP), erythrocyte sedimentation rate(ESR),complete blood count (CBC), serum electrolytes.

we will investigate the relation between vitamin D deficiency and severity of Inflammatory Bowel Disease
