Systemic lupus erythematosus in the older age group: computer analysis

Area of Science:

• Rheumatology
• Immunology
• Internal Medicine

Background:

• Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with variable clinical manifestations.
• Age is a potential factor influencing SLE presentation, disease activity, and treatment outcomes.

Purpose of the Study:

• To investigate the impact of age on the clinical course of systemic lupus erythematosus (SLE).
• To compare disease characteristics, organ involvement, laboratory findings, therapeutic requirements, and prognosis between older and younger SLE patients.

Main Methods:

• Prospective study analyzing data from 234 SLE patients meeting ARA criteria.
• Comparison of 16 older patients (≥51 years) with 218 younger SLE patients.
• Evaluation of clinical signs, symptoms, organ system involvement, laboratory data, and treatment parameters.

Main Results:

• Older SLE patients exhibited increased discoid lupus, photosensitivity, and pulmonary fibrosis.
• Similar incidence of malar rash, alopecia, arthritis, arthralgia, myalgia, and serositis in both groups.
• Older patients had lower rates of oral ulcers, Raynaud's phenomenon, cutaneous vasculitis, neuropsychiatric manifestations, leukopenia, hypocomplementemia, and proteinuria.
• Older patients required lower corticosteroid doses and shorter azathioprine therapy durations.

Conclusions:

• Age influences the clinical phenotype of systemic lupus erythematosus (SLE).
• Older SLE patients may present with a milder disease form characterized by specific dermatologic and pulmonary manifestations.
• Older individuals with SLE demonstrate a potentially better response to therapy, necessitating adjusted treatment strategies.
