Serum Immunoglobulin E and Vitamin D Levels in Asthma Patients in Enugu, Nigeria: Association with Asthma Control.

Background: Asthma symptoms are often mediated by changes in immune responses to allergens measured by the levels of immunoglobulin E (IgE) and non-protein regulators such as 25-hydroxycholecalciferol (25 (OH) vitamin D3). The relationship between serum levels of IgE, 25 (OH) Vitamin D3, and asthma control in asthma patients remains unclear.

Objective: To measure the serum IgE and 25 (OH) vitamin D3 levels in asthma patients and determine their relationship with patient's asthma control.
