Empirical Comperative Study Of Variation Blood Level Antibody Vitamin D at Different Groups Of Patients Compared Healthy Peoples
Empirical Comperative Study Of Variation Blood Level Antibody Vitamin D at Different Groups Of Patients Compared Healthy Peoples
The aim of this study is to detect antibodies to vitamin D in the serum at Different Groups
 of patients and healthy volunteer. A second goal is to find the relation between Vitamin D
 Antibody and Vitamin D level.
Vitamin D and its metabolites have a significant role in the calcium homeostasis and bone
 metabolism. Vitamin D deficiency as measured by serum 25(OH)D below 20 ng/mL (50 nmol/L) may
 contribute to the development of osteoporosis and Osteomalacia.

 Several studies have clearly demonstrated that low 25(OH)D levels are associated with more
 comorbidities, higher estimated cardiovascular risk and autoimmune diseases.

 Exposure to the ultraviolet (UV) rays in sunlight is the major source of vitamin D. other
 sources are dairy products enriched with vitamin D.

 Vitamin D deficiency can result from inadequate exposure to sunlight, malabsorption including
 inflammatory bowel disease, celiac disease and patients undergone resection of the small
 intestine and inadequate intake of dairy products enriched with vitamin D.

 Another possible explanation for vitamin D deficiency is the presence of neutralizing
 autoantibodies to vitamin D.

 The aim of this study is to detect antibodies to vitamin D in the serum at Different Groups
 of patients and healthy volunteer

 At least 64 Blood samples of Patients and healthy volunteer will be tested for the presence
 of auto-antibodies using an ELISA reader.

 The result will compare antibody-positive and antibody-negative individuals with respect of
 serum 25(OH)D level and other variables and to find the relation between Vitamin D Antibody
 and Vitamin D level.
