Vitamin d Levels in Children With Bacterial Meningitis

June 5, 2015 updated by: Gang Liu

Association of Serum 25-hydroxyvitamin D Levels and Outcomes in Children With Bacterial Meningitis

The purpose of this study is to determine whether deficiency of Vitamin D has association with outcomes of children with bacterial meningitis.

Study Overview

Status

Unknown

Conditions

Detailed Description

Vitamin D deficiency has been proved in serious diseases patients, including patients in shock, however, few study have been done about association between deficiency of Vitamin D and outcomes of children with bacterial meningitis.

in our study, we will observe incidence of complication and severity of complication between patients who have different Vitamin D status.
