Systemic lupus erythematosus and inflammatory bowel disease

Area of Science:

• Rheumatology
• Gastroenterology
• Internal Medicine

Background:

• Systemic lupus erythematosus (SLE) and inflammatory bowel disease (IBD) are chronic autoimmune disorders.
• Co-occurrence of SLE and IBD is rare, necessitating further investigation into their relationship.

Purpose of the Study:

• To review and synthesize existing literature on patients diagnosed with both SLE and IBD.
• To characterize the clinical presentation, disease course, and specific features of patients with coexisting SLE and IBD.

Main Methods:

• Comprehensive literature search of English-language publications.
• Case series analysis of patients with documented SLE and IBD diagnoses.
• Comparative analysis of clinical features between patients with coexisting diseases and those with SLE alone.

Main Results:

• SLE typically precedes IBD, with ulcerative colitis being the most common IBD subtype.
• Patients with both conditions exhibited reduced photosensitivity, arthritis, and serositis compared to SLE-only patients.
• Absence of neurological disorders and overt nephritis was noted.
• Increased prevalence of anemia and thrombocytopenia observed.
• Patients demonstrated a generally benign clinical course for both SLE and IBD.

Conclusions:

• The coexistence of SLE and IBD may be associated with a distinct clinical phenotype and a more indolent disease progression.
• Further research is warranted to elucidate the underlying mechanisms and optimize management strategies for this patient cohort.
