Effectiveness of Probiotics in Patients of Mild to Moderate Rheumatoid Arthritis

Phase 3

Completed

• Conditions: Rheumatoid Arthritis

• Registration Number: NCT06594822
• Lead Sponsor: King Edward Medical University

Brief Summary

To assess the effectiveness of probiotics when given in combination with standard therapy in patients of mild to moderate rheumatoid arthritis

Detailed Description

This study was conducted on the patients presenting to the Rheumatology out-patients department of the Department of Medicine, King Edward Medical University, Mayo hospital, Lahore from 24th August, 2023 till 23rd February, 2024. A total of 88 patients of either sex, between the age group of 18 to 70 years and having an established diagnosis of rheumatoid arthritis (RA), \[as proved on history, X-rays and biologic markers like Rheumatoid Factor (RF) and Anti-cyclic citrullinated protein antibodies (anti-CCP antibodies), Erythrocyte Sedimentation Rate (ESR) and C- reactive protein (CRP)\] and having mild to moderate disease activity score (DAS-28 score between 2.6 to \<5.1) were selected via simple random sampling.

After approval from the Board of Studies (BOS) and Advanced Study Research Board (ASRB) of King Edward Medical University, Mayo Hospital, Lahore, all patients conforming to the selection criteria were enrolled in the study. Informed written and verbal consent was taken from all the participants. Patient's demographic data was obtained and recorded in a predesigned proforma. Patients were divided into two groups by computer generated method. Group A comprised 44 patients who received standard therapy \[analgesics, glucocorticoids, any Disease modifying anti-rheumatic drug (DMARD)\] alongwith probiotic (Bacillus clausii), whereas Group B also comprising 44 patients received standard therapy alone. Lab investigations like complete blood counts (CBC), C- reactive protein (CRP), liver function tests (LFTs) and renal function tests (RFTs) were done at baseline and then on follow up visits at 45 and 90 days. Disease activity score (DAS-28) was assessed on baseline then on each subsequent visit to monitor response to treatment. Mild RA patients had a DAS-28 score between 2.6 to 3.1 and moderate RA patients had a DAS-28 score between 3.1 to \<5.1. Effectiveness was defined in terms of reduction of DAS-28 score of ≥0.6 from the baseline based on European League against Rheumatism (EULAR) response rates. Pancytopenia, derangement in LFTs and RFTs twice from the baseline as a result of treatment resulted in exclusion from the study.

Data was analyzed using computer software Statistical Package for Social Sciences (SPSS) version 26.0. Quantitative variables like age, DAS-28 score were expressed as mean and standard deviation (Mean±SD). Qualitative variables including gender were expressed as frequency and percentages. Chi- square test was used to compare response between the two groups. P value ≤0.05 was considered statistically significant.
