Conditions

Rheumatoid Arthritis

Brief summary

Rheumatoid arthritis (RA) is a systemic chronic auto-inflammatory disorder which imposes a remarkable burden of morbidity and mortality on global health. The complex interaction between genetics, environment, and immunological response contribute to RA pathogenesis. Current treatment comprises conventional disease-modifying anti-rheumatic drugs (DMARDs) followed by biological DMARDs, if necessary, to achieve low disease activity or remission. Therapeutics used in RA had limitations in tolerability, access, and response duration and magnitude. Consequently, implementation of safe adjunctive treatment for RA is urgently needed to boost the therapeutic response.

Interventions

DRUGMethotrexate

Methotrexate (MTX) is an anti-metabolite most commonly used in chemotherapy and immunosuppressant in auto-immune diseases. This activity describes the indications, action, and contraindications for Methotrexate as a valuable agent in treating a wide variety of diseases.

DRUGParoxetine

Paroxetine is a type of antidepressant known as a selective serotonin reuptake inhibitor (SSRI). It's often used to treat depression, and sometimes obsessive compulsive disorder (OCD), panic attacks, anxiety or post-traumatic stress disorder (PTSD).

Inclusion criteria

* Aged 23-57 years fulfilling 2010 American College of Rheumatology - European League against Rheumatism (ACR-EULAR) classification criteria for RA (12) and had active inflammatory RA with no limit in disease duration. * Patients received MTX, nonsteroidal anti-inflammatory drugs, selective cyclooxygenase-2 inhibitors, acetaminophen, and low dose of oral corticosteroids will be allowed to enroll the trial * Intravenous, intra-articular or intramuscular corticosteroids; intra-articular hyaluronate sodium; biological DMARDs; and other DMARDs will not be permitted less than 4 weeks before the first dose of paroxetine.

Exclusion criteria

Design outcomes

Primary

MeasureTime frameDescription
The primary efficacy end point will be the change in the 28-joints disease activity score (DAS28).3 monthsA DAS28 value of greater than 5.1 indicates high disease activity. The values of 3.2 \< DAS28 ≤ 5.1 and DAS28 ≤ 3.2 are indicative of moderate and low disease activities, respectively. If DAS28 value is less than 2.6, the patients may be considered to be in remission phase
