E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Oral glucocorticoid (GC) therapy leads to a rapid and profound effects on bone metabolism.The gut microbiota is involved in regulating bone metabolism.Lactobacillus reuteri (LR) has been shown to have probiotic, health-promoting effects.The aim of this randomized, double-blind, placebo-controlled trial is to investigate if daily supplementation with LR, compared to placebo, can prevent the negative effects of oral GC on bone turnover and on blood glucose regulation in healthy young adults. |

E.1.1.1 | Medical condition in easily understood language |
The aim of this trial is to investigate if daily supplementation with Lactobacillus reuteri, can prevent the negative effects of oral glucocorticoid on bone turnover in healthy young adults. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary outcome: between group per cent change in bone turnover markers between baseline (day 16, prior to GC treatment start) and day 23 (7 days after starting oral GC). 1. Serum osteocalcin 2. Serum CTX 3. Serum P1NP
|
|
E.2.2 | Secondary objectives of the trial |
1. Change in blood glucose levels (area under the curve) using continuous glucose monitoring (CGM) between baseline (day 14-16) and days 16-23. 2. Change between baseline (day 16) and day 23 in serum markers of intestinal permeability (endotoxin levels). 3. Change between baseline (day 16) and day 23 in serum and feces markers of intestinal inflammation (lipocalin-2 and calprotectin) 4. Change in the gut microbiota composition between baseline (day 16) and day 23.
