- Brief Summary
The purpose of this study is to investigate the potential therapeutic effects of the cardiac glycoside digoxin and the secondary bile acid ursodeoxycholic acid (UDCA) on synovial inflammation and disease activity when administered as add-on treatments to the current DMARDs treatments for rheumatoid arthritis patients with variant disease activity.
- Detailed Description
This study is a randomized, open-labeled, controlled prospective study to evaluate the potential therapeutic effects of the cardiac glycoside digoxin and the secondary bile acid ursodeoxycholic acid (UDCA) on synovial inflammation and disease activity when administered as add-on treatments to the current DMARDs treatments for rheumatoid arthritis patients with variant disease activity. The study population will be rheumatoid arthritis patients attending the Physical Medicine, Rheumatology and Rehabilitation Department at Menoufia University Hospital, Menoufia, Egypt. A total of 90 rheumatoid arthritis patients who will meet the inclusion criteria will be enrolled in this study. The 90 participants will be divided into 30 rheumatoid arthritis patients who will receive placebo + the current DMARDs treatments of rheumatoid arthritis for 24 weeks and serve as the control group, 30 rheumatoid arthritis patients who will receive DMARDs + digoxin 25 mg every other day for 24 weeks and the last 30 rheumatoid arthritis patients who will receive DMARDs + ursodeoxycholic acid (UDCA) 500 mg/day for 24 weeks. Clinical Examinations and laboratory parameters will be performed and measured at the beginning of the study, 12 weeks and 24 weeks after randomization to evaluate the efficacy of digoxin and UDCA in the treatment of rheumatoid arthritis.

Group Intervention Description Ursodeoxycholic acid (UDCA) Ursodeoxycholic acid (UDCA) 500 mg Participants in this arm will receive ursodeoxycholic acid (UDCA) 500 mg/day + DMARDs for 24 weeks. Control Placebo Participants in this arm will receive Placebo with the current DMARDs treatments for rheumatoid arthritis for 24 weeks. Digoxin Digoxin 0.25 mg Participants in this arm will receive digoxin 0.25 mg every other day + DMARDs for 24 weeks.
- Primary Outcome Measures
Name Time Method Changes from Baseline in Clinical Disease Activity Index (CDAI) Score Baseline, after 12 weeks, after 24 weeks To evaluate the effect of the use of digoxin and UDCA as an add-on therapy in patients with rheumatoid arthritis by evaluating the change from baseline in the clinical findings as measured by Clinical Disease Activity Index (CDAI) scores. A lower CDAI score from Baseline would mean improvement in disease activity and an increase in CDAI score from Baseline would mean an increase in disease activity or a worsening in disease activity. Scores: 0.0-2.8 = Range for Remission; 2.9-10.0 = Range for Low disease activity; 10.1-22.0 Range for Moderate disease activity; 22.1-76 Range for High disease activity. Total range is from 0-100, with the high scores representing high disease activity.
Changes in C-Reactive Protein (CRP) Values and Erythrocyte Sedimentation Rates (ESR) Baseline, after 12 weeks, after 24 weeks C- reactive Protein (CRP) values and Erythrocyte Sedimentation Rate (ESR) will be made at baseline and after 12 as well as 24 weeks to determine the number of patients whose test result improved or worsened CRP value (normal range \<1.0 mg/dl). ESR (normal range 0-28 mm/hr) . If the value is increased, the disease activity worsened. If the value is reduced the disease activity is improved.
- Secondary Outcome Measures
Name Time Method Changes from baseline Measurement of IL-17A and HIF-1α at 12 and 24 weeks Baseline, after 12 weeks, after 24 weeks Serum IL-17A and HIF-1α levels will be measured by means of the human enzyme-linked immunosorbent assay (ELISA) technique according to the manufacturer's protocol.
Numbers of participants with treatment-related adverse events Baseline, after 12 weeks, after 24 weeks The adverse events in each group will be observed and documented during the whole procedure to show the safety of the treatment.
