Rheumatoid Arthritis in Sickle-Cell Population: Pathophysiologic Insights, Clinical Evaluation and Management.

Area of Science:

• Rheumatology
• Hematology
• Immunology

Background:

• Improved survival in Sickle Cell Disease (SCD) due to medical advancements.
• Prolonged survival in SCD patients is associated with an increased incidence of Rheumatoid Arthritis (RA).
• RA is a chronic inflammatory disorder rarely reported in SCD patients previously.

Purpose of the Study:

• To review the epidemiological association between SCD and RA.
• To discuss common pathogenetic mechanisms linking SCD and RA.
• To highlight diagnostic and therapeutic challenges in managing RA in SCD patients.

Main Methods:

• Literature review of epidemiological data on SCD-RA association.
• Analysis of common pathophysiological pathways including endothelial dysfunction, inflammatory cytokines, and oxidative stress.
• Discussion of clinical diagnostic challenges and therapeutic strategies for RA in SCD.

Main Results:

• Established epidemiological link between Sickle Cell Disease and Rheumatoid Arthritis.
• Identified shared mechanisms like endothelial dysfunction, inflammatory cytokines, and oxidative stress.
• Highlighted difficulties in diagnosing RA in SCD patients and risks associated with RA treatments.

Conclusions:

• SCD patients surviving longer are at increased risk for developing RA.
• Understanding shared pathogenetic mechanisms is crucial for management.
• Careful consideration of therapeutic options is needed to balance RA treatment efficacy with infection and immunosuppression risks.
