Brief Summary

Rheumatoid arthritis (RA) is a long-term inflammatory condition that leads to gradual damage of joints lined by synovial membranes, along with various potential effects outside of the joints. While RA can affect any joint, it typically involves the metacarpophalangeal, proximal interphalangeal, and metatarsophalangeal joints, as well as the wrists and knees. Symptoms related to the joints and surrounding tissues include swelling, tenderness upon touch, morning stiffness, and significant difficulty moving the affected joints

Outcome Measures

Primary Outcomes (1)

  • change in Disease Activity Score (DAS28)

    Calculation of 28-joint count Disease Activity Score (DAS28) using C- reactive protein level (CRP) according to the following formula: DAS28-CRP = \[0.56\*√ (tender joint count) + 0.28\*√ (swollen joint count) + 0.36\*ln (CRP+1)\] \*1.10 + 1.15\] will be done where sever disease activity ≥ 5.1, moderate disease activity from 3.2 to 5.1, mild disease activity from 2.6 to 3.2, and remission \<2.6.

    3 months

Study Arms (2)

Control group

ACTIVE COMPARATOR

will receive the traditional therapy of RA for three months.

Drug: Methotrexate

Pentoxifylline group

ACTIVE COMPARATOR

will receive 400 mg pentoxifylline two times daily plus the traditional therapy of RA for three months.

Drug: MethotrexateDrug: Pentoxifylline

Interventions

Methotrexate (MTX) is a chemotherapy agent and immune-system suppressant. It is used to treat cancer, autoimmune diseases, and ectopic pregnancies. Types of cancers it is used for including breast cancer, leukemia, lung cancer, lymphoma, gestational trophoblastic disease, and osteosarcoma. Methotrexate is also used to treat rheumatoid arthritis and other inflammatory conditions.

Control groupPentoxifylline group

Pentoxifylline (also known as oxpentifylline) is a methylxanthine derivative with strong hemorrheologic effects. In the United States, it is primarily used to treat intermittent claudication. Studies in both humans and animals have demonstrated that pentoxifylline therapy induces various physiological changes at the cellular level
