Correlation between vitamin D metabolites and rheumatoid arthritis with osteoporosis by ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).

Introduction: Our aim is to study the correlation between vitamin D metabolites and osteoporosis in rheumatoid arthritis (RA) by ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). At the same time, other influencing factors and serum biomarkers of osteoporosis in patients with RA were studied.

Materials And Methods: Patients with RA admitted from January 2020 to December 2020 were selected at our hospital.

The Role of Vitamin D in Combination Treatment for Patients With Rheumatoid Arthritis.

The aim of this study is to evaluate the clinical efficacy of vitamin D (VitD) supplementation in terms of response to treatment and improvement of disease activity in rheumatoid arthritis (RA). This study analyzed 1180 RA patients' records treated at Mianyang Central Hospital from February 2015 to July 2019. The patients were allocated into VitD group and control group based on their medical regimens.
