Relation between Vitamin D and Uterine Fibroid

Abstract

Background: Uterine fibroids (UFs) are the most common benign tumors affecting women of reproductive age]. patients with uterine fibriod suffer from pelvic pain, menorrhagia, dysmenorrhea/dyspareunia, pressure-related symptoms, miscarriage, and subfertility. The aim of this study was to assess the relationship between occurrence, size, and clinical symptoms of uterine fibroid and the serum level of Vitamin D.
 Methods: The study was designed as an observational case control study.
 This study was conducted at Tanta University Maternity Hospital at the department of obstetric and Gynecology from March 2020 to September 2020.This study was conducted on 75 women in their reproductive age (20-45 yrs) recruited at Tanta obstetric and gynecology department (inpatient wards), they were subdivided into two groups:Group A: case group: 50 Women with uterine fibroid. Group B: control group: 25 Women with normal uterine examination and transvaginal ultrasound. Measuring the level of serum vitamin D3 in both control and women with uterine fibroid.
 Results: The age, in case group, ranged from 20-45 yrs with mean level 30.50± 4.56 yrs and in control group ranged from 20-45 with mean value 31.01+ 5.11 yrs. the diagnostic performance of vitamin D test in diagnosing uterine fibroid through illustrating sensitivity and specificity of vitamin D level to predict uterine fibroid. Area under the curve was 0.881with cut off value 14.3 ng/ml, the sensitivity of vitamin D to predict the fibroid was 79.3%, the specificity was 66.7 and test accuracy was 74.4%.
 Conclusions: The current study showed a significant association between vitamin D3 deficiency in reproductive age women and the occurrence of uterine fibroid, the mean vitamin D3 level in the case group was 13.8±7.93 ng/ml and in the control group was 20.79+8.95 ng/ml.
 
 There is correlation between vitamin D3 level and the size of uterine fibroid.
 Vitamin D3 deficiency is widely spread among the study population with 80 % prevalence while vitamin D3 insufficiency is prevalent in 14% among study participants
