The Role of Vitamin D, A, and Beta Carotene in Tuberculosis Patients With Vitamin D Receptor Gene Polymorphism

October 13, 2020 updated by: DINA KEUMALA SARI, Universitas Sumatera Utara
Recent studies showed that vitamin D and A has an effect in improving sputum conversion in tuberculosis. This study aims to find out the effect of vitamin D 1000 IU and A 6000 IU supplementation on Tuberculosis patients with vitamin D receptor gene polymorphism, who live in North Sumatera, Indonesia. This study is a randomized control clinical trial, with 48 tuberculosis patients with vitamin D receptor gene polymorphism which are TaqI and FokI participating, divided into two groups, each with 24 participants, which are treatment group (I) which receives nutritional counseling, vitamin D 1000 IU, vitamin A 6000 IU, and control group (C) which only receives nutritional counseling for 28 days. Patients who participated was found to be heterozygous with TaqI (T>C) or FokI (C>T) genotype variants.

Detailed Description

Recent studies showed that vitamin D and A has an effect in improving sputum conversion in tuberculosis. This study aims to find out the effect of vitamin D 1000 IU and A 6000 IU supplementation on Tuberculosis patients with vitamin D receptor gene polymorphism, who live in North Sumatera, Indonesia. This study is a randomized control clinical trial, with 48 tuberculosis patients with vitamin D receptor gene polymorphism which are TaqI and FokI participating, divided into two groups, each with 24 participants, which are treatment group (I) which receives nutritional counseling, vitamin D 1000 IU, vitamin A 6000 IU, and control group (C) which only receives nutritional counseling for 28 days. Patients who participated was found to be heterozygous with TaqI (T>C) or FokI (C>T) genotype variants. The result of this study showed that at the start, serum 25(OH)D levels in group I were lower compared to group C (19.746.59 ng/mL vs 25.21±7.57 ng/mL). Group I showed significant correlation between vitamin D level categories with sputum conversion (mean: standard deviation= 2.25±0.68 weeks). Supplementation of vitamin D 1000 IU provides an accelerated sputum conversion in tuberculosis patients with vitamin D receptor gene polymorphism.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 60 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study
